Dust collector control device and dust collector

Abstract

The invention discloses a dust collector control device and a dust collector. The dust collector control device comprises a microcontroller, a load detection module, an air volume detection module anda brushless DC motor. The input end of the load detection module is connected with the input end of the brushless DC motor. The output end of the load detection module and the output end of the air volume detection module are connected with the input end of the microcontroller. The output end of the microcontroller is connected with the input end of the brushless DC motor. The load detection module is used for detecting the counter electromotive force of the brushless DC motor in real time. The air volume detection module is used for collecting the suction force of the dust collector during working. The microcontroller controls the voltage output to the brushless DC motor according to the counter electromotive force of the brushless DC motor detected by the load detection module and the collected suction force of the dust collector during working, so as to control the rotating speed of the brushless DC motor to be constant in a preset rotating speed interval. The reliability of the dust collector is improved.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a vacuum cleaner control device and a vacuum cleaner. Background technique [0002] Vacuum cleaners are a common cleaning tool that can assist personnel to efficiently clean up and collect fine garbage or dust. Compared with traditional brooms suitable for similar tasks, vacuum cleaners are obviously more convenient, faster and more effective. [0003] At present, some vacuum cleaners have the function of adjusting the suction power, and the suction power can be adjusted according to the amount of dust on the ground to be cleaned to achieve cleaning and energy saving effects. Part of it automatically adjusts the size of the suction through infrared detection of the amount of dust. However, the cost of infrared sensors is relatively high, which puts a greater pressure on the cost of enterprises. Another part of the vacuum cleaner adjusts the size of the suction by manually ...

AI Technical Summary

Problems solved by technology

Part of the suction is automatically adjusted by infrared detection of the amount of dust. However, the cost of infrared sensors is relatively high, which puts greater pressure on the cost of enterprises.

Another part of the vacuum cleaner adjusts the suction power by manually adjusting the high and low gears. This type of vacuum cleaner is complicated to operate and inconvenient to use, and it is inaccurate to adjust the suction power by judging the amount of dust with human eyes.
