How to make a vacuum cleaner from a hair dryer. How to make a construction vacuum cleaner with your own hands with minimal costs? How does a mini vacuum cleaner work?

When conducting construction works, or during processing wooden products(this is not uncommon even in modern apartment), rises into the air a large number of dust. It settles on all horizontal surfaces, it is impossible to remove this debris with a broom and a wet rag.

The best way to clean up dirt is a vacuum cleaner.

It is not realistic to use a household vacuum cleaner during repairs or construction work, a filter instantly clogs in a conventional unit. At one time, a cyclone-type vacuum cleaner was invented, which works on the principle of a separator: heavy particles of debris are separated from the air of medium pollution, and settle in containers, bypassing the filter element.

Relatively fresh air passes through the filter without getting dirty too quickly. This technology has found its application both in stationary ventilation systems(for example, in sawmills or flour mills), and in household electrical appliances.

It is more convenient to remove construction dust with a cyclone vacuum cleaner, but a household unit will only help to clean the floor after drilling several holes in the wall. For large-scale construction, a professional device is needed.

It is possible to remove cement dust, or prepare the surface for pouring a liquid floor, only with the help of a construction vacuum cleaner.

This technique does an excellent job of its task, but you have to pay a lot of money for it. If professional cleaning is needed irregularly, you can make a construction vacuum cleaner with your own hands.

Two concepts of construction vacuum cleaners

The task of any vacuum cleaner, especially a construction one, is to remove dust and debris as much as possible and at the same time not to raise dust into the air. In this regard, the designers are struggling with various filters, the two directions of which are the main ones. We will consider them.

Apparatus with water filter

Water vacuum cleaners are manufactured industrially, including for the home. The essence of the work is as follows: the input stream of polluted air passes through a container with water, the dust remains in the liquid, and we get purified air from the outlet pipe.

Homemade water filter k ordinary vacuum cleaner- video

Advantages this method: perfect cleaning of even the smallest particles. Disadvantages: high power of the unit is required (a significant part of the energy is lost in overcoming water resistance), water vapor has a detrimental effect on the electric motor.

Important! If you remove building dust containing gypsum or cement with such a vacuum cleaner, you must immediately pour out dirty water after cleaning. Otherwise, the precipitate may solidify.

For manufacturing, you will need the following materials:

plastic container with a tight-fitting lid
plastic sewer pipes suitable diameter
sealant
aluminum tape(You can use tape to connect floor insulation or linoleum).

How to make a vacuum cleaner? A homemade unit assumes a 6,000 rpm engine. This part can be removed from the juicer. Please note that not all electrical appliance motors are designed for long-term service. Therefore, when choosing an engine, be guided by the rule: the motor must endure a heavy load and have protection against overheating.

What to do if you cannot find anything other than a juicer part?

In this case, it is advisable to equip it with a thermal fuse rated at 126 ° C. The copper cross-section must correspond to the dissipation power, so this temperature may not be suitable for the motor you choose. It should be noted that the 130 ° C limit is the average for which most transformers are designed.

What can you take as the basis of a homemade unit?

Many are interested in how to make a vacuum cleaner with their own hands.

You can take as a basis:

The hood motor with the Axial model will not work, since it is used in models in the low-cost segment and does not have the required power.
Disused vacuum cleaner motor.
Engine washing machine.
Refrigeration compressor motor.

Refrigerator Engine Application

How to make a vacuum cleaner from It will be difficult to pick up a part, since the speed of rotation of the shaft is at different models refrigerated trucks varies. If you are assembling a vacuum cleaner, then a strict 6000 rpm will be required. The old rocker type compressors are rated for 3000 rpm.

Crank-connecting rod modifications have a speed half as much, and linear inverter units are not at all suitable for assembly.

There is an electric motor inside the reciprocating compressor. If you cut open the case and remove the motor, then it will be suitable for any purpose. It has high power and quiet operation.

Asynchronous motors are rarely used. For example, the manifold configuration is plugged in if speed control is not required.

Using a washing machine motor

The design of washing machines assumes the presence of a collector motor. Its speed is regulated by a thyristor key. If the motor is powered directly from the outlet, then the rpm will be high, but they will not reach 6000 in the absence of a belt gear. In this case, the spin function is quite achievable.

How to make the unit suck in dust?

Commercials often talk about the vacuum created in a vacuum cleaner. The engine supposedly contributes to the discharge, into which the drawn in air stream rushes. But is it really so? Rather not, because at negative pressure, a bypass valve is connected to ensure equilibrium. But this is not the essence of the work. A hermetically sealed housing is used to suck in dust, thanks to which the flow of nitrogen and oxygen molecules rushes in the desired direction. The container does not play any role in this case.

If you adhere to the factory configuration, then a steel or plastic bucket is required, the bottom of which has an opening for air intake. The motor is mounted on the axle, and something like a squirrel cage is installed on the shaft. The air stream is captured by the blades and thrown out onto the perimeter. This provides traction. A hose is sealed to the bottom. We will assume that the assembly of the vacuum cleaner with your own hands is complete.

How does a mini vacuum cleaner work?

How to make a mini vacuum cleaner? The unit speed regulation is performed according to the thyristor circuit. Any electronic part from an old vacuum cleaner, washing machine, or food processor will come in handy.

The main thing is the slicing method, not the engine power. But the key is also overheating. It is easy to understand whether it matches if we compare the power of the device from which the diagram was taken with the power of the engine. If the thyristor index is low, then it is advised to attach a radiator to it, and forced cooling is already available.

How to make a container for a homemade vacuum cleaner?

The vacuum cleaner is designed in such a way that it will not work without a container.

Suitable for a homemade unit:

ordinary bag;
container filled with water;
cyclone chamber.

Filtration of the bag is problematic. If you will be vacuuming crumbs off the table, this will work. The type of container is selected according to the type of waste. For example, dust collection is best done with a water filter or cyclone chamber. Both container types are easy to design. The unit itself turns out to be stationary. If such a device is used by a gardener, then it can be hoisted on a cart and moved around the garden.

The cost of stationary models of vacuum cleaners is high, so a home-made design will be very useful.

The simplest container model is a large tank filled with water. It plays the role of an aquafilter. In this case, the dust will sink. The inlet of the hose is made with a view so that the flow collides with a water obstacle. A typical flat-bottomed box is two-thirds filled with water. In addition, a partition hangs from the ceiling above the filter surface. All dust settles in the water and drowns. Such a device requires periodic cleaning. This design will not be suitable for gardening, as the weight of the water is large. Therefore, it is replaced with air.

When assembling do-it-yourself garden vacuum cleaners, adhere to the following rules:

Air enters the tall barrel tangentially.
Along the axis of the container, up to about two-thirds of the height, there is a pipe that provides an outlet.
Garbage settles to the bottom due to the fact that it is carried to the periphery by centrifugal force.
The air flow comes out in the center.
The smallest particles enter the engine anyway. Therefore, it is recommended to equip the container with a HEPA filter at the outlet. It is not worth saving on this. Otherwise, you will have to constantly expose the engine to lubrication. If the vacuum cleaner sucks in the water, it will end up in the barrel.

Such a homemade vacuum cleaner for a gardener is great. The unit can be made versatile. For example, cut the barrel to fit the diameter of the tank with standard sizes and equip the device with a van for movement. This will clean up the whole park.

How to make a mini vacuum cleaner from a plastic bottle?

Today, almost everyone has a computer at home. As you know, its body is periodically clogged with dust, which interferes with the cooling of many parts. The circuits should be vacuumed from time to time. To facilitate the process, you can use a homemade mini vacuum cleaner.

For the manufacture of the unit you need:

fan from the computer;
plastic bottle;
hose;
polystyrene;
power supply unit 220 V / 14 V;
insulating tape;
paralon.

Progress

The plastic bottle is cut in half. The part that remains with the cork is taken. A filter is cut out of the foam rubber. It is inserted into the neck. The material should fit snugly.
A hole is made in the plug into which the hose is inserted.
The cork is screwed onto the bottle.
The fan is taken from the computer (its corners are smoothed). It is inserted into the bottle in such a way that during operation the air flow is directed towards the wide side of the bottle.
The place where the cooler is located is wrapped with insulating tape. A wire is used for a strong fixation.
The power supply is connected to the fan. The red wire goes to the plus side and the black wire to the minus side.

How to make a do-it-yourself industrial vacuum cleaner?

How to make appointments? One of these units is based on the Ural PN-600 model.

You will need:

Bulgarian;
a branch pipe with a diameter of 4 cm and a length of 20 cm;
plastic bucket with handle and lid;
Scotch;
insulating tape;
drill;
self-tapping screws;
glue;
medical bandage.

Stages of work

First of all, it is necessary to modify the "Ural" waste bin. For this purpose, the wheels are unscrewed from the very bottom with a screwdriver. The holes are sealed with tape.
Then you need a grinder, with which the latches and fasteners are removed. A plug is installed, rewound with insulating tape.
A hole with a diameter of 43 mm is drilled into the bottom.
Gaskets are cut from the seal, the thickness of which is 4 mm.
The gasket, bucket lid and centering pipe are placed in the bin.
Using a drill, a hole with a diameter of 2 mm is made.
The cover is fixed with self-tapping screws 4.2x10 mm.
An external opening is made for the suction inlet. It is outlined at an angle of 15 degrees. The hole is cut with metal scissors.
The branch pipe is fixed with self-tapping screws. An ordinary medical bandage is used for sealing, which is impregnated with Titan glue. The bandage is wound around the nipple.

Second way

To assemble the unit in the second way, you will need:

old home vacuum cleaner;
oil-based filter;
20 L bucket with tight-fitting lid;
PP corners 90º and 45º with a diameter of 40 mm;
meter of plastic pipe with a diameter of 45 mm (suitable corrugated pipe 2 m long and 40 mm in diameter).

Assembling the device

To begin with, take the lid of the bucket. A hole is cut in it at an angle of 90º. Then a corner of the same size is inserted.
When a corner is inserted into the lid, all the cracks are covered with glue using a construction gun.
A slot is made in the side of the bucket, into which a 45º corner is inserted. All cracks are also covered with glue.
To connect the corrugation to the corner, it is necessary to cut a piece of pipe with a diameter of 40 mm. The corrugation should fit snugly. If it does not fit on the inlet pipe, then you can resort to using the model from the siphon on the kitchen sink.
The narrow end of the corrugation is fitted to the 40 mm pipe. The other end connects to the opening of the vacuum cleaner.
To extend the service life of the filter, pull a nylon stocking over it.

Can an old vacuum cleaner come in handy?

There is an old vacuum cleaner at home. What can be done from an unnecessary unit?

If the device works, then it can be used for another purpose. Some methods require technical training, since alteration of equipment is dangerous. In particular, you should understand the principle of operation of motors.

This article will describe the safest methods.

Air blower

If you connect the hose to the outlet, which is available in most models, you can get a unit for inflating rubber mattresses, pools for children and other similar things. At the same time, the vacuum cleaner container needs preliminary cleaning of debris residues.

What can a Typhoon vacuum cleaner do?

What to make of an old Typhoon vacuum cleaner? The principle of operation of the unit is characterized by a high level of performance.

The body of a Soviet-made vacuum cleaner is the best fit for creating a device for chopping grass. It has a top hole of a suitable diameter. Typhoon is a great option, but not the only one.

What else can you apply?

The body of the device can be replaced with a cylinder-shaped container. For example, a pot, a bucket, or a piece of pipe is used.
The 180 watt motor comes from an old washing machine.
A hacksaw blade is used as knives. For the rack, you will need a rectangular profile with a size of 15x15 mm.
The sleeve for fastening the knives is turned on lathe... Its height is 40 mm.
The motor, with the pulley removed, is attached to the container by means of studs from the bottom.
To clamp the knives, use 32 mm water pipe nuts.
A hole is cut for the motor shaft.
For reliable fixation on the shaft, a pair of holes with a diameter of 7 mm and an M8 thread for locking bolts are made in the bushing.
On the motor shaft, from the reverse side, platforms are machined to increase the level of reliability of fastening the sleeve with locking bolts.

Making a grain crusher

To make a grain crusher, a person must have experience with technology. Self-production devices without relevant knowledge are not recommended.

A sheet of plywood is taken in a square shape. An electric motor is fixed on it so that the shaft goes down 40 mm.
The steel plate is mounted on a threaded shank. It is secured with nuts, bushings and washers.
The leading edges are sharpened on both sides of the axle.
An axial hole is made in the middle of the insert.
To create the working chamber of the future unit, a body is made in the form of a ring. It is based on the correct design of the part assumes the bending of the edges of the rings outward. They should form 10 mm flanges. It is with their help that the body is attached to the base. A sieve is screwed onto them.

Making an attraction for children

What can be made from an old kids vacuum cleaner? If the motor of the unit is running, then it can be used for the attraction.

For this purpose, the tennis ball is pierced through with a pin, so that the ends of the pin are on either side of the ball.

After that, the propeller is made. A jar made of polystyrene is used. The propeller is attached to the top of the ball. One strip is enough for him. It is cut out with scissors.

The propeller is pierced in the middle and pushed onto the pin shaft. For speed and ease of rotation, it is advised to make bearings from beads. They are attached to both sides of the strip.

The upper edge of the pin is folded in such a way that there is no large backlash on the axis.

Such a ball can be launched into the air through the outlet. If desired, the ball is decorated with sparkles.

Conclusion

This article has described how to make a vacuum cleaner. There are many assembly options. It has also been described what can be done from a vacuum cleaner.

Remember that without appropriate technical knowledge it's not worth getting down to business. In this case, it will be difficult to make a vacuum cleaner yourself. It is better to seek help from a specialist.

Many of us often sit in front of the computer: some work, others play games, but in any case, sometimes it is necessary to clean the work or play space, namely computer desk, keyboard, which accumulate dust, crumbs, and so on. Especially for such cases can be purchased at specialized stores mini USB vacuum cleaner, but you can make it yourself from improvised means.

Watch the manufacturing process of a mini USB vacuum cleaner in the video clip:

So, to make our own mini vacuum cleaner, we need a 50 ml syringe, a piece of tin plate, a motor, a felt-tip pen, scissors, a glue gun and a USB cable from the old charger, mouse or keyboard.

The first step is to take care of the turbine that will suck in the dust. To do this, you need to cut a circle from a tin plate under the inner diameter of the syringe, which by the way is equal to the diameter of the syringe plunger. To cut a circle, you just need to put the piston on a plate, circle it with a felt-tip pen and cut the resulting circle with scissors.

After that, you need to divide the circle into eight equal parts, draw another small circle in the middle using a toothpaste or healing gel lid.

After that, it remains only to make radial cuts and slightly bend the turbine blades, making another hole in the very middle for mounting on the motor.

The next step is to take a regular disc holder and cut off all the excess parts, leaving the middle one and glue the turbine to it with a glue gun. After that, it remains only to attach the turbine to the motor.

In order for the air to pass freely through the body of the mini vacuum cleaner, and the engine is not overloaded, you need to make two small slots in the syringe piston and glue the engine strictly in the center.

There are no special difficulties with the upper part of the vacuum cleaner: you just need to glue the neck of the plastic bottle along with the cork, on which you need to make a hole and insert a tube through it.

To quickly remove dust from hard-to-reach areas of the workplace in the workshop, son's computer and other household appliances, made a mini vacuum cleaner with my own hands... It took only two to make it. plastic containers, small drive and one free evening. The design turned out to be not only useful, but also easy to use.

On a DC motor with a voltage of 12 V, from the side of the axis, a protective casing made of sheet metal (photo 1) d 100 mm was fixed.

I made an impeller from plastic (photo 2) - I cut out a circle d 95 mm with a jigsaw and glued to it on one side perpendicular ribs measuring 30 × 15 mm. The finished part was fixed on the motor axis with glue from a heat gun.

I assembled a waste bin from a cut PET bottle and a plastic bucket. In the upper part of the case, I mounted a tube from a syringe for attaching a hose.

From a tin can required diameter(must match the diameter of the PET bottle) made an air intake (photo 3). In the walls of the container, I drilled several holes d 5 mm, and in the bottom in the center I fixed the cut tube from the syringe.

Fixed the part on protective casing bolts so that the clearance between the impeller and the bottom of the intake is approximately 7 mm.

I installed the finished unit (motor with intake) in the housing and drilled holes in the plastic at the level of the holes on the intake. The junction for the reliability and rigidity of the attachment missed with superglue.

To connect the device to the network, I soldered the wires of the 12 V power supply to the motor contacts. Using a metal adapter, I fixed the hose to the tube in the housing.

Making a homemade vacuum cleaner with your own hands is very easy. Such a device will come in handy in various everyday situations.

Need a vacuum cleaner urgently? And it broke or was not at hand? Did you know that you can do it yourself? For this, it is enough to have the most common objects that are present in any apartment: empty bottles, wires, scraps of tubes, hoses, broken toys that you were sorry to throw away. First of all, you need to get somewhere a small working electric motor. This is the backbone of the basics. It can be borrowed from a broken children's toy or some unnecessary electrical appliance. Having obtained it, you can start making a small vacuum cleaner.

Take plastic bottle from under the lemonade and cut off the neck in the place where it expands. Measure the excess part from the neck cut and cut it off so that the remaining space is enough for the dust collector and motor.
Fan. You can borrow an old fan from the computer system unit. If not, find a piece of soft metal of the right size. Can be from under a can of beer. The main thing is that it can be easily cut with scissors and then bent. The diameter of the fan wings must match the inside diameter of the bottle. Cut out a circle, mark it into 6-8 equal parts. Cut the scribing lines, leaving 5-10 mm to the center of the circle.
In the center, make a hole for the motor rotor, and bend the fan blades at an angle so that they suck in air during rotation, and not vice versa. Fasten the fan and motor rotor with glue, being careful not to distort the connection.
Make holes in the bottom of the bottle to let the air flow out. Attach the motor to the bottom of the bottle. A plastic cover comes in handy for this. Glue it to the motor, after passing the wires from it into the hole on the side.
Place a fan inside the bottle and glue it to the bottom. To the top of the bottle on inner side glue the seal.
Make a ring out of any wire. Place the ring on top of the gasket and glue a circle of thin fabric onto it. Close the structure with the top of the bottle. Then glue a small hose to it. The attachment can be made from half of an unnecessary plastic vial.

As you can see, making a homemade vacuum cleaner with your own hands is quite easy. Such a device will come in handy in various everyday situations. The power of a small vacuum cleaner, for example, is quite enough to clean the keyboard from dust and bread crumbs. The made device can be easily carried from place to place, not only in the house. It can be used to clean seats and panels in the vehicle interior.
