[0022] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0023] Reference Figure 1-4 , an embodiment of a suction cup exhaust structure of the utility model is proposed:

[0024] A suction cup exhaust structure includes a suction cup shell 3 and an elastic suction cup body 4 located at the bottom of the suction cup shell 3. The elastic suction cup body 4 gradually tilts downward from the center to the periphery, and the lower surface of the elastic suction cup body 4 is a suction concave surface 22 formed by joining multiple arc surfaces. A connecting structure 5 is provided between the top center of the elastic suction cup body 4 and the center of the suction cup shell 3. Exhaust ribs 31 are evenly provided at the bottom of the suction cup shell 3, and the exhaust ribs 31 extend from the connecting structure 5 to the periphery of the suction cup shell 3. There is an exhaust spacing d1 between the exhaust ribs 31 and the elastic suction cup body 4, and the exhaust spacing d1 gradually increases from the connecting structure 5 to the periphery of the suction cup shell 3.

[0025] When the user applies pressure to the suction cup shell 3, since a connecting structure 5 is provided between the top center of the elastic suction cup body 4 and the center of the suction cup shell 3, the suction cup shell 3 first applies pressure to the center of the elastic suction cup body 4, causing the top center of the elastic suction cup body 4 to begin to deform, and at the same time, the suction cup shell 3 gradually approaches the elastic suction cup body 4; then the exhaust pressure rib 31 applies pressure to the elastic suction cup body 4, and since there is an exhaust spacing d1 between the exhaust pressure rib 31 and the elastic suction cup body 4, the exhaust spacing d1 gradually increases from the connecting structure 5 toward the periphery of the suction cup shell 3, and the exhaust pressure rib 31 will gradually apply pressure to the elastic suction cup body 4 from the connecting structure 5 toward the suction cup shell 3, further causing the elastic suction cup body 4 to deform from the center to the periphery, thereby causing the air between the center of the elastic suction cup body 4 and the wall to be discharged from the center to the periphery, and the air between the center of the elastic suction cup body 4 and the wall is discharged as much as possible, thereby increasing the suction strength of the suction cup.

[0026] like Figure 2As shown, the elastic suction cup body 4 includes a frame 1 and a soft rubber disc body 2. The soft rubber disc body 2 covers the lower surface and edge of the frame 1, and the frame 1 includes an arc pressure surface 11 made of a high-return material, and the arc pressure surface 11 gradually tilts downward from the center to the periphery. The connecting structure 5 is arranged between the top of the arc pressure surface 11 and the center of the suction cup shell 3, and the exhaust pressure rib 31 is used to apply pressure to the arc pressure surface 11.

[0027] Since the upper edge of the soft rubber disc body 2 is provided with a force-bearing protrusion 21, and the soft rubber disc body 2 covers the lower surface and edge of the frame 1, the force-bearing protrusion 21 is located at the periphery of the frame 1. The bottom of the suction cup shell 3 is provided with a convex tooth 32 for pressing the force-bearing protrusion 21. In the process of flattening the elastic suction cup body 4, since the distance d2 between the force-bearing protrusion 21 and the convex tooth 32 is greater than the exhaust spacing d1 when the suction cup shell 3 does not apply pressure to the elastic suction cup body 4, the convex tooth 32 applies pressure to the edge of the soft rubber disc body 2 only after the exhaust pressure rib 31 is completely pressed on the elastic suction cup body 4, that is, the convex tooth 32 applies pressure to the edge of the soft rubber disc body 2 only after the air between the center of the elastic suction cup body 4 and the wall is exhausted, so that the edge of the soft rubber disc body 2 is tightly attached to prevent air from entering the elastic suction cup body 4, and further make the soft rubber disc body 2 tightly attached to the wall.

[0028] like Figure 3 As shown, a plurality of protruding teeth 32 are arranged circumferentially at the bottom of the suction cup housing 3. The force-bearing protrusion 21 is an annular protrusion, which is arranged around the edge of the soft rubber disc body 2. The protruding teeth 32 can evenly apply pressure to the edge of the soft rubber disc body 2, which is conducive to pressing the edge of the soft rubber disc body 2 onto the wall.

[0029] like Figure 4 As shown, the connection structure 5 includes a card slot 51 provided on the suction cup housing 3 and a buckle 52 provided on the top of the arc pressure surface 11, and the buckle 52 is snapped into the card slot 51. A force-bearing boss 12 is provided on the top of the arc pressure surface 11, and the buckle 52 is provided on the force-bearing boss 12. A force-applying portion 33 pressed against the force-bearing boss 12 is provided at the bottom of the suction cup housing 3. When the user applies pressure to the suction cup housing 3, the force-applying portion 33 is closest to the arc pressure surface 11 and first applies force to the top center of the arc pressure surface 11, so that the center of the arc pressure surface 11 is first deformed and exhausted.

[0030] A pressing boss 34 is provided at the center of the upper surface of the suction cup shell 3 , and a clamping groove 51 is provided on the pressing boss 34 , which is conducive to the suction cup shell 3 to concentrate the force on the center of the upper surface of the elastic suction cup body 4 first.

[0031] The suction cup housing 3 is provided with a vent hole 35, and air can enter between the suction cup housing 3 and the elastic suction cup body 4 through the vent hole 35, so as to avoid the suction cup housing 3 and the elastic suction cup body 4 forming a negative pressure when the suction cup housing 3 presses the elastic suction cup body 4, thereby affecting the suction force of the suction cup. In addition, the suction cup housing 3 is provided with a vent hole 35, which can reduce the material of the suction cup housing 3, thereby reducing the production cost.

[0032] like Figure 3 As shown, in this embodiment, the exhaust ribs 31 are straight ribs, and in this embodiment, four pairs of exhaust ribs 31 are provided, and the exhaust ribs 31 in the same pair are parallel to each other, and the four pairs of exhaust ribs 31 are arranged in a cross shape, so that uniform pressure can be applied to the elastic suction cup body 4. In other embodiments, the arrangement of the exhaust ribs 31 is not limited, as long as uniform pressure can be applied to the elastic suction cup body 4.

[0033] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
