The motor of the vacuum cleaner rotates at a high speed, and the external air is sucked from the suction port, so that a certain vacuum is generated in the dust box. The dust enters the dust filter bag in the dust box through the floor brush, the connecting pipe, the handle, the hose and the main suction pipe, and the dust is left in the dust filter bag. , the filtered air enters the motor through a layer of filter. This layer of filter is a protective barrier to prevent the dust bag from breaking and dust being sucked into the motor. The air entering the motor flows out through the motor. Due to the constant wear and tear of the carbon brushes during the operation of the motor, a filter is added before it flows out of the vacuum cleaner. The finer the filter material, the cleaner the air can be filtered, but the lower the air permeability, which will affect the air volume sucked by the motor and reduce the efficiency of 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 stronger the vacuuming ability. This pressure difference is generated by the vacuum cleaner using the high-speed rotation of the motor to drive the fan blade group to rotate, so that a partial vacuum is generated inside the vacuum cleaner. Obviously, the degree of vacuum inside the vacuum cleaner is closely related to the rotational speed of the motor. Therefore, the higher the operating speed of the motor of the same power, the stronger the suction generated.
The finer the filter material inside the vacuum cleaner, the cleaner the air is filtered. If the quality of the vacuum cleaner itself is poor and the air permeability is not good, it will affect the suction air volume of the motor, thus affecting the efficiency of the vacuum cleaner, but for the user, the comfortable and clean material is very good. important. The air permeability of the vacuum cleaner is low and should be made into a wave shape, which can mainly increase the ventilation area, and the filter material can be cleaned repeatedly.
2. How to choose a vacuum cleaner
1. Choose a vacuum cleaner according to the size of the space
Most households will take care of them often, and there is no need for a vacuum cleaner with too much power. Usually between 1200w-2000w, do not pursue too high power, the higher the power, the more power consumption.
2. Pay attention to the noise level of the vacuum cleaner
Vacuum cleaners will make noise, and the size of the noise depends on the quality of the motor, the power, and the strength of the seal. It is not recommended to buy a vacuum cleaner with a decibel higher than 80db. If it exceeds 85db, it will be uncomfortable.
3. Choose a vacuum cleaner by details
The length of the vacuum cleaner wire is about 5 meters. If there are fewer sockets, it is recommended that the wire be longer. There is a vacuum cleaner with stepless speed regulation, which can control the power, and is environmentally friendly and energy-saving.
