Description

Surface treatment equipment

Technical field

This application relates to the technical field of surface treatment equipment, in particular to a surface treatment equipment.

Background technique

Surfaces such as glass and building walls are easily polluted by particles in the air, so they need to be cleaned frequently. In related technologies, cleaning machines are used to clean glass, building walls and other surfaces.

In the related art, Chinese Patent CN102920393B discloses a cleaning machine and a path control method thereof. The cleaning machine includes 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 extracts air from 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 driven at least one cleaning element to generate a displacement on the plate.

Refer to Figure 1 of Chinese Patent CN102920393B, the pump module extracts 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 drive module and rotates under the drive of the drive module. . The airflow channel for pumping air from the pump module is composed of the cover plate of the driving module and the lower shell of the cleaning machine. The lower shell has multiple air inlet holes, and the cleaning element has multiple air inlet holes and is connected with the lower shell to make The air between the cleaning element and the plate is drawn by the pump module. However, since the cleaning element has to rotate relative to the lower housing of the cleaning machine, the sealing performance of the connecting part of the lower housing and the cleaning element is not strong, so that the suction effect is reduced and it is difficult to form an effective suction force; and the connecting part is easily affected by fine dust, etc. As a result, the rotation of the cleaning element is not smooth, thereby affecting the cleaning effect. As shown in Figure 1 of the patent, the connecting part is exposed to the outside of the cleaning machine, which makes it easier for dust to enter the connecting part, thereby affecting the rotation of the cleaning element. In addition, as shown in Figures 1 and 2 of the patent, the airflow channel through which the pump module of the patent extracts air makes the housing of the cleaning machine and the drive module highly integrated, which is not conducive to mass production and fault repair.

In order to solve this problem, the usual method in the related art is 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 will also bring noise pollution; In order to prevent the connecting part of the lower shell and the cleaning element from being affected by fine dust, the related art is achieved by improving the connection effect, but this method makes the connection method too complicated.

Further, referring to Figures 2 and 3 of Chinese Patent CN102920393B, the cleaning machine includes two cleaning elements. In order to ensure the cleaning effect, it is usually necessary to wipe the plate repeatedly, but repeated wiping causes the cleaning efficiency to decrease, and the cleaning time is doubled. This requires the user to wait longer, which also increases the need for battery power of the cleaning machine. How to improve cleaning efficiency while ensuring cleanliness has become an urgent problem to be solved.
