Description
Technical Field
The invention relates to the technical field of surface treatment equipment, in particular to a gear speed change transmission device of surface treatment equipment and the surface treatment equipment.
Background
The surfaces of glass, building walls and the like are easily polluted by particles in the air, so that the surfaces of the glass, the building walls and the like need to be cleaned frequently, and a cleaning machine is adopted in the related art to clean the surfaces of the glass, the building walls and the like.
In the related art, chinese patent CN102920393B discloses a cleaning machine and a path control method thereof, 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 to the pump module and the driving module and controls the at least one cleaning element to generate a displacement on the plate.
Referring to fig. 1 of chinese patent CN102920393B, the pump module pumps air between the cleaning element and the plate, but as shown in fig. 1 of the patent, the cleaning element is fixedly connected to the driving module and is rotated by the driving module. The air flow channel for pumping air of the pump module is composed of a cover plate of the driving module and a lower shell of the cleaner, 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 case of the cleaning machine, the sealing property of the connection portion between the lower case 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 or the like, which results in the unsmooth rotation of the cleaning member, thereby affecting the cleaning effect. As shown in fig. 1 of the patent, the connection is exposed to the outside of the cleaner, so that dust particles more easily enter the connection and thus 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 an air flow channel of air, so that the integration level of the shell and the driving module of the cleaner is very high, which is not beneficial to mass production and fault repair.
In order to solve the problem, it is common practice in the related art to increase the power of the pump module and use a high-rotation motor, but this solution increases the cost of the pump module and the high-rotation motor also causes noise pollution, and in order to prevent the connection portion of the lower case and the cleaning member from being affected by dust particles or the like, the connection is performed by improving the connection effect in the related art, which makes the connection manner too 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 generally required to wipe the plate repeatedly, but the repeated wiping results in a reduction in cleaning efficiency, and the time required for cleaning is multiplied, which requires the user to wait for a longer time, and also increases the need for the battery power of the cleaning machine. How to improve the cleaning efficiency while ensuring the cleanliness is an urgent problem to be solved.
