As shown in fig. 1 to 3, the cleaner 500 has one suction port, and the suction port of the cleaner 500 is connected to the second outlet 420b of the suction passage of the cleaner head 400.
Fig. 4 shows a sectional view of the first body 410 of the dust removing head 400 shown in fig. 3, in which the air blowing channel is formed.
As shown in fig. 4, in the illustrated embodiment, ultrasonic air flow generating devices 4101, 4102 are provided in the air blowing passage of the dust removing head 400. The ultrasonic air flow generating devices 4101, 4102 are adapted to convert the compressed air flow F1 input from the first inlet 410a into an ultrasonic air flow F2.
As clearly shown in fig. 3, the aforementioned ultrasonic air flow F2 is blown out from the first outlet 410b of the air blowing passage of the dust removal head 400. In this way, the surface of the device 10 to be cleaned can be struck with the ultrasonic air flow F2 blown out from the first outlet 410b of the air blowing passage of the dust removing head 400, thereby blowing up dust particles on the surface of the device 10 to be cleaned. In the embodiment, the high-frequency ultrasonic airflow generated by the dust removing head impacts the surface of the device at high frequency, so that dust on the surface of the device can be blown more effectively, and the dust removing effect is improved.
However, it should be noted that the air blowing passage of the dust removing head of the present invention is not limited to the illustrated embodiment, and for example, the ultrasonic air flow generating device may not be provided in the air blowing passage. In this way, the surface of the device to be cleaned can be directly impacted with the flow of compressed air blown out from the first outlet, and dust on the surface of the device can be blown up as well.
With continued reference to fig. 3, in the illustrated embodiment, the blown-up dust particles enter the suction passage of the cleaner 500 from the second inlet 420a along with the suction airflow F3 generated by the cleaner 500 under suction of the cleaner 500, and are sucked into the cleaner 500.
As shown in FIG. 3, in one embodiment of the present invention, the first outlet 410b of the air blowing channel of the cleaner head 400 is positioned in the second inlet 420a of the air suction channel of the cleaner head 400.

As shown in fig. 3-5, the outlet end 412 of the first body 410 at the first outlet 410b is centrally located in the second inlet 420 a. A smooth arc-shaped chamfer is formed at an outer side of the outlet end 412 of the first body 410 to reduce wind resistance when the cleaner 500 sucks, so that blown dust can be more easily sucked into the suction passage of the cleaner head 400.
As shown in fig. 4, in one exemplary embodiment of the present invention, the ultrasonic gas flow generating devices 4101, 4102 include first aperture portions 4101 and second aperture portions 4102 alternately arranged in the flow direction of the gas flow. The aperture of the first aperture part 4101 is set not to be equal to the aperture of the second aperture part 4102. For example, the ratio of the aperture of the second aperture part 4102 to the aperture of the first aperture part 4101 may be set to be greater than or equal to 50.
As shown in fig. 1 to 3, in the illustrated embodiment, the dust removing system further includes an air compressor 100, an outlet of the air compressor 100 being communicated with the first inlet 410a of the dust removing head 400 for delivering compressed air to the first inlet 410a of the dust removing head 400.

In one embodiment of the present invention, the filter 200 can filter out dust particles having a diameter equal to or greater than 0.3u from the compressed air to improve the cleanliness of the air supply.
As shown in fig. 1-3, in the illustrated embodiment, the dust removal system further includes a static eliminator 300 to eliminate static electricity on the device 10 before dust particles on the device 10 are blown off with the dust removal head 400. In this way, after eliminating static electricity on the device 10, the electrostatic attraction force between the dust particles on the surface of the device 10 and the surface of the device 10 can be eliminated, so that the dust particles on the surface of the device 10 can be more easily blown up.
As shown in fig. 1 to 3, in the illustrated embodiment, the static eliminator 300 communicates with the outlet of the filter 200, so that at least a part of the compressed air output from the air compressor 100 is delivered into the static eliminator 300. The static eliminator 300 is adapted to generate a high voltage corona discharge so as to ionize the compressed air inputted into the static eliminator 300 into a large number of positive and negative ions by the high voltage corona discharge and neutralize the static electricity on the surface of the device 10 with the ionized positive and negative ions.
Note that the static eliminator of the present invention is not limited to the foregoing embodiment, and may be any suitable device in the prior art capable of eliminating static electricity on the surface of a device.

In one embodiment of the present invention, in order to optimize the dust removal effect, the dust removal pressure, the dust removal time, and the moving speed of the device should be set reasonably.
It should be noted that the cleaning head of the present invention is not limited to the illustrated embodiment, and for example, the cleaning head 400 may be a molded integral piece.
In the foregoing embodiment of the present invention, the air blowing passage and the air suction passage are integrated on the same dust removal head 400, without separately providing one air suction head and one air suction head. Therefore, the integration level of the dust removal system is improved, and the dust removal system is more compact in structure, simpler and easy to use.
