Problems solved by technology

like figure 1 As shown, in order to make the body of the window cleaning robot A tightly adsorbed on the glass surface B, a sufficient vacuum must be maintained, but as the vacuum increases, the friction between the rag 200 and the glass surface B will be caused. If the vacuum is too small, although it can reduce the friction between the rag 200 and the glass surface B, it will cause insufficient suction, which will cause the body to fall easily and affect normal use.

Embodiment 1

[0024] figure 2 and image 3 They are schematic diagrams of the positions of the window cleaning robot of the present invention in two states; Figure 4 for figure 2 Schematic diagram of the local structure of M; Figure 5 It is a schematic diagram of the bottom structure of the window cleaning robot of the present invention. Such as Figure 2 to Figure 5 As shown, in this embodiment, the adsorption type self-moving device is a window cleaning robot, including a robot body, the body includes an organic base 100, and the base 100 is provided with a walking unit 300 and an outer covering Timing belt 310. The bottom of the machine base 100 includes a cavity 110 , which communicates with a vacuum source 400 , and around the cavity 110 is a sealing assembly for sealing with the adsorption surface, ie, the glass surface B. After sealing between the sealing assembly and the adsorption surface, it forms a vacuum chamber with the cavity 110 , and the sealing assembly connects w...

Embodiment 2

[0027] Figure 6 It is a structural schematic diagram of the second embodiment of the window-cleaning robot of the present invention. Such as Figure 6 As shown, the structure of the window cleaning robot in this embodiment is basically the same as in Embodiment 1, the difference is that, as required, the straight portion 511 of the movable support 500 extends a skirt 550 toward the outside of the vacuum chamber, so The skirt 550 is attached and sealed to the adsorption surface. The setting length of the rag 200 can be the same as the length of the movable support 500, that is to say, in this embodiment, the rag 200 is pasted on the lower surface of the movable support 500, and the sticking length is the same as the flat surface of the movable support 500. The total lengths of the straight portion 511 , the raised portion 512 and the skirt 550 are the same.

[0028] The working principle of this embodiment will be described in detail below in conjunction with the embodiment...

Embodiment 3

[0031] Figure 7 It is a structural schematic diagram of a window-cleaning robot in Embodiment 3 of the present invention. Such as Figure 7 As shown, this embodiment is an improvement on the basis of the second embodiment above. In this embodiment, a skirt 550 is also attached to the adsorption surface on the outer edge of the movable support 500 , but the setting position of the rag 200 on the movable support 500 is different from that of the second embodiment. Specifically, as Figure 7 As shown, the setting length of the rag 200 is the same as the sum of the lengths of the straight portion 511 and the raised portion 512 of the movable bracket, and one end of the rag 200 is embedded in the inner side of the skirt 550, the rag 200 The bottom surfaces of 200 and skirt 550 are flush. As can be seen from the above, in this embodiment, the skirt structure is also used to increase the contact area, but the difference is that in this embodiment, the part in contact with the gl...

Abstract

An adsorption type self-moving device is provided with a machine base (100), a walking unit (300) and a functional unit, the bottom of the machine base includes a cavity (110), and the cavity communicates with a vacuum source (400). The outer periphery of the cavity is provided with a sealing assembly for sealing with the adsorption surface. After sealing between the sealing assembly and the adsorption surface, it forms a vacuum chamber with the cavity. The bottoms meet. In the present invention, elastic expansion parts are arranged between the sealing assembly and the machine base, and at the same time, through the setting of the skirt structure and the selection of flexible materials with a small friction coefficient, the skirt is directly affected by the adsorption surface on the poor sealing environment. The effect of atmospheric pressure improves the sealing of the vacuum chamber without hindering the walking of the adsorption self-moving device; the invention has a simple structure but can effectively absorb excess pressure, and balance the adsorption force and friction force during normal walking and safe adsorption.

Description

technical field [0001] The invention relates to an adsorption type self-moving device, which belongs to the technical field of manufacturing small household appliances for daily use. Background technique [0002] With the increasing intelligence of human life, the adsorption self-moving device represented by the window cleaning robot is more and more widely used. Therefore, how to make the window cleaning robot work safely and normally on different glass has become an important issue for the product. The top priority of the request. figure 1 It is a structural schematic diagram of an existing window cleaning robot. Such as figure 1 As shown, the existing window-cleaning robot A mainly includes a base 100 and a rag 200 arranged on the base 100, which is adsorbed on the glass surface under the action of a vacuum source 400, and relies on the walking unit 300 and the rag 200 arranged outside it. A synchronous belt (not shown) completes the walking action. From the perspecti...
