In this embodiment, a rectifier circuit formed by a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) is used to supply power to the filter cleaning apparatus 100.

In the present embodiment, the sub-controller 50 is electrically connected to the driving motor 22 in the filter cleaning apparatus 100 to control the rotation of the driving motor 22. The sub-controller 50 includes a sub-control unit 501, a communication circuit 502, and a driving circuit 503; the sub-control unit 501 is configured to receive a control signal sent by the main controller 40, and send a start-stop control instruction and a rotation direction control instruction according to the control signal; the communication circuit 502 is used for realizing communication with the main controller 40; the driving circuit 503 is configured to receive a control instruction provided by the sub-control unit 501 and provide a driving current to the driving motor 22. In this embodiment, the rotation direction control instruction includes a forward rotation control instruction and a reverse rotation control instruction, which can control the driving circuit 503 to provide currents in different directions to the driving motor 22, so that the driving motor 22 is in a forward rotation working state and a reverse rotation working state; the driving circuit 503 may specifically adopt a power supply circuit form of an H-bridge circuit. By the forward rotation and the reverse rotation of the driving motor 22, the dust on the filter 200 can be cleaned more deeply.

Further, in the present embodiment, in order to reasonably control the operation of the filter cleaning apparatus 100, a dust sensor 60 is further disposed on the dust suction device 30, the dust sensor 60 is configured to detect the amount of dust in the filter cleaning apparatus 100 and feed a detection signal back to the main controller 40, and the main controller 40 determines the start-stop state of the filter cleaning apparatus 100 according to the detection signal. Specifically, a minimum threshold value of the dust amount is set in the dust sensor 60 in advance, when the filter 200 is cleaned, the dust sensor 60 will detect a large amount of dust first, and the corresponding dust amount value will be large; after a period of cleaning, the dust amount will decrease, the corresponding dust amount will also decrease, when the current dust amount is lower than the minimum threshold, it indicates that the filter cleaning apparatus 100 has cleaned the dust in the filter 200, at this time, the dust sensor 60 feeds back the detection signal to the main controller 40, and the main controller 40 determines the shutdown state of the filter cleaning apparatus 100 according to the detection signal. That is, when the dust sensor 60 cannot detect dust, the dust suction device 30 is automatically powered off, so that the power of the battery of the dust suction device 30 is not consumed due to continuous operation after the user leaves the dust suction device 30; secondly, the safety of power utilization is also ensured.

It should be noted that the dust sensor 60 not only detects only dust in the filter cleaning apparatus 100, but also detects the amount of dust when the dust suction apparatus 30 corresponds to another apparatus. The detection of the amount of dust of other devices based on the dust sensor 60 is not the gist of the invention of the present application, and therefore, is not specifically explained herein; one possible implementation scheme is that the infrared emitter and the infrared receiver are arranged on two opposite sides of a dust suction pipeline of the dust collector, and the dust quantity related information is obtained by detecting pulse signals of the infrared receiver. Of course, the dust sensor 60 may be provided in the filter cleaning apparatus 100, and then only the amount of dust in the filter cleaning apparatus 100 is detected.

The control system 300 for cleaning the filter provided by the embodiment of the application comprises: a dust suction device 30, a main controller 40, a sub-controller 50, and a filter cleaning device 100; the main controller 40 is arranged on the dust suction device 30, and the sub-controller 50 is arranged on the filter cleaning device 100; the dust suction device 30 is electrically connected with the filter cleaning device 100, and the main controller 40 controls the start and stop of the filter cleaning device 100 through the sub-controller 50. The control system can realize the automatic cleaning of the filter cleaning device 100, thereby improving the cleaning efficiency; and under the condition of no user supervision, the automatic power-off can be realized, the electric quantity exhaustion of the dust suction device 30 due to continuous work is avoided, the energy is saved, the power utilization safety is improved, and the user experience is further improved.

Although the present application has been described with reference to the preferred embodiments, it is not intended to limit the present application, and those skilled in the art can make variations and modifications without departing from the spirit and scope of the present application, therefore, the scope of the present application should be determined by the claims that follow.
