The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed, and the air is sucked from the suction port to make the dust box generate a certain vacuum. 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 from being sucked into the motor. The air entering the motor flows out through the motor. wear, so 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 poorer the air permeability, which affects the air volume sucked by the motor and reduces the efficiency of the vacuum cleaner. But for the user, comfort and cleanliness is the main thing.
Its air permeability is low, so it is made into a wave shape to increase the air permeability. Some of this filter material can also be washed repeatedly. Any filter material has a "life", that is, the pores of the filter material have been blocked by small particles of dust after long-term use.
Most small household appliances are series motors, such as vacuum cleaners and soymilk machines, which have carbon brushes. The advantage of this motor is that it can obtain large torque at low speed. It can also be used for AC and DC 2.
The vacuum cleaner motor (VACUUM CLEANER MOTOR) is the heart of the vacuum cleaner. The main types of vacuum cleaner motors are: dry vacuum cleaner motor (THRU-FLOW), dry and wet vacuum cleaner motor (BY-PASS). The vacuum cleaner motor consists of two parts: the motor part and the fan part. Since the vacuum cleaner motor has high requirements on the speed, generally 20,000-30,000 rpm, the motor mainly uses a series motor, also known as a series motor.
The motors used in vacuum cleaners are divided into copper wire motors and aluminum wire motors. Copper wire motors have the advantages of high temperature resistance, long life, long single operation time, etc., but the price is higher than that of aluminum wires; Aluminum wire motors have the characteristics of low price, but poor temperature resistance, low melting point, and life is not as long as copper wires .
