Background

Surfaces such as glass and building walls are easily polluted by particles in the air, so that the surfaces need to be cleaned frequently, and in the related art, a cleaning machine is adopted to clean the surfaces of the glass and the building walls.

In the related art, chinese patent CN102920393B discloses a cleaning machine and a path control method thereof, wherein the cleaning machine comprises at least one cleaning element, a pump module, a driving module and a control system. At least one cleaning element and the plate define at least one space. The pump module pumps the air in the at least one space, so that the cleaning element is adsorbed on the plate. The driving module drives the at least one cleaning element. The control system is coupled with the pump module and the driving module and controls the at least one driven cleaning element to generate displacement on the plate.

Referring to figure 1 of chinese patent CN102920393B, the pump module pumps air between the cleaning element and the plate, but as shown in figure 1 of the patent, the cleaning element is fixedly connected to the driving module and driven by the driving module to rotate. The air flow channel for pumping air by the pump module is composed of a cover plate of the driving module and a lower shell of the cleaning machine, a plurality of air inlets are formed in the lower shell, and a plurality of air inlets are formed in the cleaning element and connected with the lower shell, so that air between the cleaning element and the plate is pumped by the pump module. However, since the cleaning member is rotated relative to the lower casing of the cleaning machine, the sealing performance of the connecting portion between the lower casing and the cleaning member is not strong, so that the suction effect is reduced and it is difficult to form an effective suction force; and the connection portion is easily affected by dust particles, etc., resulting in unsmooth rotation of the cleaning member, which in turn affects the cleaning effect. As shown in fig. 1 of the patent, the connecting portion is exposed to the outside of the cleaning machine, so that fine dust can more easily enter the connecting portion to affect the rotation of the cleaning member. In addition, as shown in fig. 1 and 2 of the patent, the pump module of the patent pumps the airflow channel of the air, so that the integration level of the housing and the driving module of the cleaning machine is high, which is not beneficial to mass production and fault repair.

To solve this problem, it is common practice in the related art to increase the power of the pump module and use a high-speed motor, but this solution increases the cost of the pump module, and the high-speed motor also causes noise pollution; in order to prevent the coupling part of the lower case and the cleaning member from being affected by fine dust, etc., the related art has achieved by improving the coupling effect, which, however, makes the coupling means complicated.

Further, referring to fig. 2 and 3 of chinese patent CN102920393B, the cleaning machine includes two cleaning elements, and in order to ensure the cleaning effect, it is usually necessary to repeatedly wipe the plate member, but the repeated wiping results in reduced cleaning efficiency and doubled cleaning time, and therefore, the user is required to wait for a longer time, which also increases the battery power requirement of the cleaning machine. How to improve the cleaning efficiency while ensuring the cleanliness is an urgent problem to be solved.
