What causes vacuum cleaners to eat dust?

The vacuum cleaner has a huge suction power in it, so it can suck all these substances into the machine. The working principle of the vacuum cleaner is to use the huge attraction to melt all the dust on the ground into the container, and on the contact surface of the vacuum cleaner, it has a filter The existence of this filter can distinguish the dust from some substances larger than the dust. <>

You will find that the suction power generated by the vacuum cleaner in the process of working is very large, such a powerful suction, it can. Anything can be accommodated, so in the process of work, this powerful suction can completely suck all the dust in our home. The vacuum cleaner can be said to be an indispensable cleaning tool in the home, maybe when you use cleaning tools like brooms or sweeping robots to clean up, some relatively large garbage in the home is easy to find, and it is also relatively easy to be cleaned.

But relatively speaking, some fine dust is difficult to clean, because these fine dust itself is relatively small in size and weight, so you can't completely clean it. At this time, if there is a vacuum cleaner, then this problem can be solved very well. Because the vacuum cleaner has a huge suction power in it, then this suction power can encompass all the substances.

The principle of its work is actually to use this series to produce an attraction to these dusts, and then absorb all of them into the vacuum cleaner, which is relatively simple, a bit like using the wind direction to work. It's just that it's not going outward, it's the inward direction of the wind that translates into a huge attraction to bring the dust in. Therefore, you will find that in the process of working with the vacuum cleaner, if you come into contact with him, you will feel that he has a very large suction.

Generally, there is some pressure inside, and the greater the pressure difference, the more powerful the vacuum cleaner will become. The passing pressure is also caused by using the speed of the motor to rotate the fan blades.

In fact, there is wind, because the pressure inside and outside is different, so there is a flow of air, so that you can inhale dust.

This is because the suction power of the vacuum cleaner is very large, so it can suck out dust and garbage on the ground or in some places.

Under normal circumstances, it is connected to the circuit, and some dust can be removed by means of electrical energy, and it also has a strong adsorption capacity, so it can be adsorbed.

Because the suction power of the vacuum cleaner is very strong, it can instantly suck up all the dust, so the cleaning ability is very strong, and it is very easy to use furniture and good things.

This is because the pressure inside the vacuum cleaner is relatively small during transportation, so it can "eat" dust.

A vacuum cleaner is a household cleaning appliance that can be sucked off the ground. Dust and dirt, as long as it is connected to the power supply, it can be used, so why can a vacuum cleaner suck up dust? How does a vacuum cleaner work?

Let me help you answer your doubts.

In the vacuum cleaner, there is a small electric motor and an impeller. As soon as the electricity is connected, the electric motor drives the impeller to rotate very quickly, driving the air out of the vacuum cleaner.

At this time, the outside air comes in to replenish, and at the same time, the dust on the ground is brought into the vacuum cleaner.

The vacuuming capacity of a vacuum cleaner is related to the pressure difference between the inside and outside of the vacuum cleaner.

The greater the pressure difference, the greater the suction capacity. This pressure difference is generated by the high-speed rotation of the vacuum cleaner to drive the fan group to rotate, so that a local vacuum is generated inside the vacuum cleaner. Obviously, the degree of vacuum inside the vacuum cleaner is closely related to the speed of the motor.

Therefore, the higher the speed of the motor of the same power, the stronger the suction power generated. Vacuum cleaners generally use a series motor. The magnetic field windings of a series motor are connected in series with the armature, and the current in the magnetic field windings varies with the load.

In a vacuum cleaner, the lighter the load on the motor, the greater its starting torque and the higher the rotation speed, up to 8,000 to 25,000 revolutions per minute, so that a large vacuum can be generated inside the vacuum cleaner. With this vacuum, the vacuum cleaner can be used to vacuum with the pressure difference between the inside and outside.

The vacuum cleaner removes dust, mainly because it has an electric exhaust fan mounted on its "head". There is an air impeller on the rotating shaft of the exhaust fan, after the power is on, the exhaust fan will produce extremely strong suction and pressure at a speed of 5000 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 action of this pressure difference, the air containing dust is inhaled. Dust and other debris enter the dust filter bag through carpet or floor brushes, long pipes, elbows, hoses, and hose joints in turn, and dust and other debris are trapped in the dust filter bag, and the air is purified by the filter and discharged by the tail of the body.

Because the gas is heated as it passes through the motor, the gas discharged from the tail of the vacuum cleaner is hot.

The vacuum cleaner's vacuum bin is equipped with a dust collection box, and the dirt is left in the dust box, and when the box is full, it can be taken out and cleaned with water. The vacuum cleaner is equipped with different parts to complete different cleaning tasks, such as a floor brush to clean the floor, a flat brush to clean sofa tops, bed sheets, curtains, etc., and a small nozzle to remove dust in small corners and dirt in some household appliances.
