Problems solved by technology
However, this treatment method is to suck the dusty air into the air path before processing. When the wall with a lot of dust is absorbed, a lot of dust will accumulate on the filter, which needs to be cleaned or replaced frequently.

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] The invention mainly includes a suction cup, a base, a vacuum pump, a two-position two-way solenoid valve, a screw rod, a conductive shrapnel, a brush and a spring. It is characterized in that before the adsorption, the adsorption device is vertically pressed down, the screw rod passes through the screw hole in the center of the suction cup base, and the linear motion is changed into a rotary motion, driving the brush to rotate and wipe the wall surface, when the screw rod rotates to When there is no screw position, the screw rod stops rotating, and the brush also stops rotating at this time. The downward pressure action continues to move the screw rod upward, compressing the conductive shrapnel, so that the two originally separated conductive shrapnel in the vacuum pump circuit contact each other, and the circuit is turned on.

The invention discloses a vacuum adsorption device adapted to a wall surface with dust. The vacuum adsorption device comprises suction cups, a suction cup base, a vacuum pump, a screw rod, brushes, a two-position two-way solenoid valve, electricity-conducting elastic pieces and a spring; before adsorption, the adsorption device is pressed perpendicularly downwards, the screw rod penetrates through a screw hole in the center of the suction cup base, linear movement is changed into rotational movement, the brushes are driven to wipe the wall surface rotationally, the screw rod stops rotating when being rotated to the position without a screw, the brushes stop rotating, the downward pressing action is continued, the screw rod moves upwards, and an upper electricity-conducting elastic piece and a lower electricity-conducting elastic piece deform to make contact with each other, so that an air pump circuit is on, and adsorption is started. According to the device, the downward pressing action during adsorption is converted into the rotational movement for wiping of the wall surface, the wall surface can be cleaned before adsorption is started, after fixed circles of wiping actions are conducted, the vacuum pump is automatically opened, additional control is not required, and the device is simple in structure and relatively good in practicability.
Description
technical field [0001] The invention relates to a vacuum adsorption device for a wall-climbing robot, in particular to a vacuum adsorption device capable of adapting to dusty walls, and belongs to the technical field of adsorption device design. Background technique [0002] The adsorption device of the wall-climbing robot is an important device for its stable and efficient operation. There are many kinds of adsorption technologies for wall-climbing robots, such as magnetic adsorption, vacuum adsorption and bionic adsorption, among which vacuum adsorption is the most widely used. Vacuum adsorption uses a vacuum pump to draw the air between the suction cup and the wall, so that a negative pressure is formed between the suction cup and the wall, and under the action of atmospheric pressure, the robot can resist the overturning moment. When working on a dusty wall surface, the dust will increase the gap between the suction cup and the wall surface, reducing the adsorption forc...
