Description

The bleed-off passage structure and surface processing equipment of surface processing equipment

Technical field

The utility model relates to surface processing equipment technical field more particularly to a kind of bleed-off passages of surface processing equipment Structure and surface processing equipment.

Background technique

The surfaces such as glass, construction wall are easy to be polluted by the particle in air, it is therefore desirable to often cleaning, in the related technology The surfaces such as glass, construction wall are cleaned using cleaner.

In the related technology, Chinese patent CN102920393B discloses a kind of cleaner and its controlling of path thereof, this is clear Clean machine includes an at least cleaning element, a pump mould group, a driving mould group and a control system.An at least cleaning element and the plate Define an at least space.Pump mould group extracts the air in an at least space, so as to making the cleaning element be adsorbed on the plate On.Driving mould group drives an at least cleaning element.Control system is coupled to the pump mould group and the driving mould group, and controls and driven A dynamic at least cleaning element is in one displacement of generation on the plate.

Referring to the attached drawing 1 of Chinese patent CN102920393B, the air between mould group extraction cleaning element and plate is pumped, but As shown in the patent accompanying drawing 1, cleaning element is fixedly linked with driving mould group, in being rotated by for driving mould group.Mould group is pumped to take out It takes the airflow channel of air to be made of the lower casing of the cover board of driving mould group and cleaner, there are multiple air inlets, clearly on lower casing There are multiple air inlets on clean element and connect with lower casing, so that the air between cleaning element and plate is extracted by pump mould group. However, cause lower casing and cleaning element coupling part leakproofness not strong since cleaning element wants the lower casing of relative clean machine to rotate, So that pumping effect reduces and is difficult to form effective suction；And the coupling part is easy to be influenced by micronic dust etc., causes clear The rotation of clean element is unsmooth, and then influences cleaning effect.As shown in the patent accompanying drawing 1, which is exposed to outside cleaner Portion so that micronic dust more easily enters the interconnecting piece, and then influences the rotation of cleaning element.In addition, such as 1,2 institute of patent accompanying drawing To show, the pump mould group of the patent extracts the airflow channel of air, so that the shell of cleaner and driving mould group integrated level are very high, it is unfavorable In mass production and fault repair.

To solve this problem, common practice is to improve the power of pump mould group in the related technology, using high-revolving motor, But this settling mode improves the cost of pump mould group, and high-revolving motor also brings along noise pollution；In order to avoid under Shell and cleaning element coupling part are influenced by micronic dust etc., are realized in the related technology by improving connection effect, and so this Mode makes connection type excessively complicated.

Further, referring to the attached drawing 2 and 3 of Chinese patent CN102920393B, which includes two cleaning elements, In order to guarantee cleaning effect, it usually needs plate is wiped repeatedly, but being wiped repeatedly causes cleaning efficiency to reduce, the time required to cleaning Multiplication needs user to wait the longer time, but also cleaner needs to increase to battery capacity thus.How to guarantee clearly Cleaning efficiency is improved while cleanliness becomes urgent problem.
