Homemade Vacuum Cleaner The principle of homemade vacuum cleaners

The working principle of the vacuum cleaner is that the vacuum cleaner motor rotates at high speed and sucks in air from the suction inlet, so that the dust box generates a certain vacuum. The dust enters the dust bag in the dust box through the floor brush, pipe, handle, hose and main straw, the dust is left in the dust bag, and the filtered air enters the motor through a layer of filter, which is a protective barrier to prevent the dust bag from breaking and the dust from being inhaled into the motor.

The air entering the motor flows out through the motor, and because the carbon brushes are constantly worn out during the operation of the motor, another filter is added before flowing out of the vacuum cleaner.

Hello dear, glad to answer for you. The concise principle of the vacuum cleaner made by science and technology is used and innovated: the principle of the homemade vacuum cleaner is also designed according to the principle of the vacuum cleaner sold on the market, mainly to make the internal air pressure lower than the air pressure of the external rough brigade, and with the help of this difference in air pressure, the dust existing in the air or on the ground is sucked into the inside of the vacuum cleaner and then filtered, leaving some dirt in the dust bag. But it is also good to clean the sheets, dust and paper scraps on the sofa.

When making your own vacuum cleaner, you first need to prepare materials, including a soap dish, a long round brush, the inner lid of an old plastic bottle, and tools such as drills, carving knives, pliers, and small screwdrivers. First, use a carving knife to carve a small rectangular hole in the old soap dish with a certain proportion, leave the hairs on the side of the brush, and remove the rest of the place, and then leave it for later use. Install the brush that is ready to shave into the soap tray with a dug hole, and bend the two ends, at this time, you can move the brush appropriately to see if the flexibility of the brush in the hole is enough, after the inspection is completed, the box of the soap box is covered, and such a simple homemade vacuum cleaner is completed.

After the self-made is completed, you can use it yourself to give it a try, put the made vacuum cleaner, put it on the bed sheet or some dusty places to rub back and forth, this is the dust part, see if there is dirt into the soap box, this is the part of vacuuming, and then turn the soap box upside down, see if there is dust inside, this is the dust collection part, if there is no problem with the inspection, then you can directly pour out the dust inside, clean it with water, and wait for the second use. Now the vacuum cleaner sold on the market is divided according to the structure, there are three ways, namely vertical, horizontal, portable, its working principle is to use its own motor to drive its blades to tell the rotation, in the sealed shell to produce a difference in air pressure, use this to absorb dust. The power of ordinary vacuum cleaners is within 400 to 1,000 watts or higher, while the power of portable vacuum cleaners is mostly below 250 watts.

If you want to buy in the market, you can buy according to your actual situation. When the vacuum cleaner is used, it must be cleaned up, otherwise when the dirt inside the filter bag is more and more tired, it will affect the entire heat dissipation effect, and also avoid accidents due to the rapid rise in temperature. When the vacuum cleaner is finished, be sure to let its temperature cool down before placing it to avoid damage due to excessive temperature.

Materials and tools needed: wooden boards, scissors, tape, electric drills, plastic bottles, metal plates.

1. First cut a round piece of wood from the board, and then drill a round hole in the circular position that can be placed on the electric drill.

2. Cut the next section of rubber liner and glue it on the side of the round hole.

3. Then use an electric drill to drill six small holes around this round hole.

4. Prepare a large empty bottle of mineral water, and then use a pen knife to cut off the shoulder and bottom of the bottle.

5. Cut two round pieces of metal on the metal cover.

6. Then make it into two fan blades of the same size.

7. Prepare a bolt of appropriate length and a few nuts, and then fix the two fan blades on the bolts.

8. Cut the lower shoulder from a smaller mineral water bottle and <>

9. Fix a piece of gauze on the incision and put it into the shoulder of the large water bottle.

10. Use a pen knife to dig a round hole in the cap of the water bottle, then insert a rubber catheter and fix it with hot melt glue.

11. When all the parts are made, start assembling the parts to the electric drill.

Working principle: the motor rotates at high speed to drive the fan to exhaust air from the hole in the tail to the outside of the cup, so that an instantaneous vacuum is formed inside and a negative pressure is formed in the cup; Under the action of this pressure difference, the outside air is drawn from the mouth of the straw to equalize the internal air pressure, and finally a suction force is generated at the mouth of the straw, and the waste is sucked into the bottle.

Here's how to make your own electric vacuum cleaner:

Operation guide, carefully adjust the position of the motor and fan blade so that the fan blade is in the center of the bottle, and when rotating, it does not touch any position on the side wall of the bottle, and then fixes. If there is a situation where parents find that they do not pump but blow the air outside after the assembly is completed, it is that the motor is connected in the opposite direction, and it is good to change the position of the two wires, which is the principle of forward and reverse rotation of the motor.

The homemade vacuum cleaner is based on Bernoulli's principle: the fan blades rotate to drive the air inside to flow backwards quickly, and the fast-flowing wind produces low air pressure, and the air pressure inside is small and the air pressure outside is large, so small objects are sucked in.

1.Preparation materials: small wooden square, propeller, battery box, No. 7 battery, small motor, gauze, screws, small switches, glue, double-sided tape, rubber bands, etc.

2.Make a bracket (fix the motor clamp and bracket with screws).

3.Glue the battery compartment and small motor.

4.Install the propellers and connect the wires.

5.Cut off the bottom of the bottle and fix the mesh to the bottle.

6.Attach the mineral water bottle to the frame and you're done.

The principle of making a simple vacuum cleaner for children is: to make the internal air pressure lower than the external air pressure, and with the help of this difference in air pressure, the dust existing in the air or on the ground is sucked into the inside of the vacuum cleaner and then filtered, leaving some dirt in the dust bag.

Extension of the basic definition of vacuum cleaner:

According to the structure, vacuum cleaners can be divided into vertical, horizontal and portable. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, and generate negative pressure of premature air in the sealed shell to suck up dust chips.

The vacuum cleaner is mainly composed of three parts: dust raising, dust vacuuming, and dust filtering, and generally includes a string commutator motor, a centrifugal fan, a dust filter and a dust collection accessory. Generally, the power of vacuum cleaners is 400-1000w or higher, and the power of portable vacuum cleaners is generally 250w and below.

The vacuum cleaner removes dust, mainly because it has an electric exhaust fan mounted on its head. There is a wind impeller on the rotating shaft of the exhaust fan, after the power is on, the exhaust fan will produce higher suction and pressure at a speed of 500 revolutions per second, under the action of suction and pressure, the air is discharged at high speed, and the air of the dust collection part at the front end of the fan continuously replenishes the air in the fan, resulting in an instantaneous vacuum inside the vacuum cleaner, and a negative pressure difference is formed with the outside atmospheric pressure, and under the effect of this pressure difference, the air containing dust is inhaled.

Prepare two plastic bags first, cover a small broom with a large plastic bag, and tie a knot at the mouth of the plastic bag. Then prepare a small plastic bag on your hand, use one hand with a small plastic bag, and rub the two with a small broom, rub for a while, then the plastic bag on the outside of the broom will produce static electricity, and the surface of the plastic bag will absorb a lot of dust.

How to choose a vacuum cleaner.

1. Consider the form and use: When purchasing a vacuum cleaner, you need to consider the purpose of buying a vacuum cleaner. If you are just cleaning the house, you can buy a regular vacuum cleaner, and if it is used to clean a large area of the ground, it is better to buy a handheld vacuum cleaner.

In addition, different types of vacuum cleaners have different shapes and different use efficiency, so you should consider them carefully when purchasing.

2. Consider the filtration form and suction: Secondly, the filtration form and suction power of the vacuum cleaner are also issues that need to be considered when buying a vacuum cleaner, because they will directly affect the actual use effect. Generally, choose a vacuum cleaner with large suction power and good filtration effect.

3. Consider the power and noise: if the filtration form is the same, the greater the power, the greater the suction power and the better the cleaning effect. However, high power also means that the louder the noise, the greater the energy consumption, so it is not necessarily necessary to have more power the better, and the impact of noise on daily life should be fully considered.

4. Consider the brand: Finally, you should also consider the brand, no matter what product should choose a high brand awareness. Because the quality of choosing a big brand is more advanced, the after-sales service is good, and the quality of different brands is not the same.

Before purchasing, you can first learn about different vacuum cleaner brands, and then choose according to your own needs.

Summary: The above is about how to make a powerful vacuum cleaner, I hope it will be helpful to everyone! A vacuum cleaner is a good helper for removing dust in your home, so it is important to choose a *** vacuum cleaner.
