Title:
SUCTION CUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/216728
Kind Code:
A1
Abstract:
A suction cup device, comprising: a suction cup body (100), wherein the suction cup body (100) is provided with a suction surface (210) which comes into contact with a surface on which the suction cup device is to be mounted; an air extraction channel (300), wherein an inlet of the air extraction channel (300) is positioned on the suction surface (210); and an air extraction assembly (400), which is arranged in the air extraction channel (300). The suction surface (210) is horn shaped, and is arranged in the circumferential direction of the air extraction channel (300); and the suction surface (210) can be gradually brought into contact, along an outer edge of the suction surface in a direction towards the air extraction channel (300), with the surface on which the suction cup device is to be mounted, so as to gradually discharge air between the suction surface (210) and the surface on which the suction cup device is to be mounted. When the suction cup device with the above structure is mounted on the surface on which the suction cup device is to be mounted, as the suction cup body is pressed or an air extraction operation is performed by the air extraction assembly, the horn-shaped suction surface (210) gradually comes into contact, along the outer edge of the suction surface (210) in the direction towards the air extraction channel, with the surface on which the suction cup device is to be mounted, so as to gradually discharge the air between the suction surface (210) and the surface on which the suction cup device is to be mounted. In this way, there are no bubbles generated between the suction surface (210) and the surface on which the suction cup device is to be mounted. The suction cup device has stable suction and a relatively strong load-bearing capacity.
