Description

Technical Field

[0001] The utility model relates to a suction cup capable of delaying the release of the adsorption state. Background Art

[0002] At present, the existing toilet seats are very limited in terms of convenience and hygiene performance. Because after using the toilet, under non-human factors, the seat ring is always horizontally placed on the toilet. Once the user forgets or is not used to lifting the seat ring, the seat ring may be frequently contaminated by urine, sewage, etc. Once the seat ring is quickly lifted, it is easy to collide with the upper cover or the water tank and generate noise, bringing a lot of troubles to people's actual use.

[0003] The bottom ring of commercial public toilets on the market can only be opened and erected manually to avoid contamination of the bottom ring during urination. Moreover, the bottom rings of commercial public toilets on the market are all bottom rings without a slow-lifting function. When the bottom ring collides with the ceramic, the noise is large, affecting the poor user experience of consumers.

[0004] Therefore, the present utility model is studied and proposed in view of the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a suction cup capable of delaying the release of the adsorption state. When the user presses down the toilet lid, it can be adsorbed on the toilet through the suction cup. When the user finishes using the toilet, the suction cup will automatically delay the release of the adsorption state.

[0006] The present utility model is realized through the following technical solutions:

[0028] The following will make a detailed description of the implementation manners of the present utility model with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] As Figures 1-6 shown, a suction cup of the present utility model that can delay the release of the adsorption state includes a mounting bracket 1 and a suction cup main body 2 that can be deformed and cooperate with the contact surface to form a sealed space. An elastically deformable deformation member 3 is provided on the suction cup main body 2, and a slit 321 that can isolate the inner cavity of the suction cup main body 2 from the outside is provided on the deformation member 3. When using the present utility model and moving the suction cup main body towards the contact surface side, the volume of the inner cavity of the suction cup main body gradually decreases, resulting in an air pressure difference between the air pressure in the inner cavity of the suction cup main body and the external air pressure. The existence of the air pressure difference causes the deformation member to deform accordingly, so that the slit becomes a slit opening that connects the inner cavity of the suction cup main body with the outside. Then, the gas in the inner cavity of the suction cup main body is blown out to the outside, facilitating the movement of the suction cup main body towards the contact surface side and improving the adsorption efficiency. When the air pressure in the inner cavity of the suction cup main body is the same as the external air pressure, the slit opening becomes a slit that isolates the inner cavity of the suction cup main body from the outside under the action of the deformation reset force of the deformation member, so that the suction cup main body and the contact surface are in a sealed state to ensure firm and reliable adsorption between the suction cup main body and the contact surface. When moving the suction cup main body towards the side away from the contact surface, the volume of the inner cavity of the suction cup main body gradually increases, resulting in an air pressure difference between the air pressure in the inner cavity of the suction cup main body and the external air pressure. The existence of the air pressure difference causes the deformation member to deform accordingly, so that the slit becomes a slit opening that connects the inner cavity of the suction cup main body with the outside. Then, external gas is sucked into the inner cavity of the suction cup main body, reducing the adsorption force of the suction cup main body on the contact surface to facilitate the separation of the suction cup main body from the contact surface, having the problems of convenient use and reasonable design.

[0031] Among them, the material of the mounting bracket 1 can be plastic. The materials of the suction cup main body 2 and the deformation member 3 can be silicone rubber or thermoplastic elastomer materials.

[0032] like Figures 1-6 As shown, the deformable member 3 includes a mounting portion 31 connected to the suction cup body 2, the mounting portion 31 is provided with an elastically deformable deformable portion 32, and the slit 321 is located on the deformable portion 32. The deformable portion 32 can be manufactured with different thicknesses to change the upper and lower lengths of the slit 321, thereby changing the time when the gas enters the inner cavity of the suction cup body, thereby realizing a suction cup device that releases the adsorption state at different times.

[0033] Furthermore, the suction cup body 2 includes a suction cup connecting part 21 which is connected to the mounting frame 1 and is hollow and has upper and lower openings, and an adsorption part 22 which is connected to the lower end of the suction cup connecting part 21 and can cooperate with the contact surface to form a sealed space; the mounting part 31 is embedded in the inner side of the suction cup connecting part 21, and the slit 321 is connected to the inner cavity of the adsorption part 22.

[0034] In order to facilitate disassembly and assembly, a clamping structure 4 is provided between the outer wall of the mounting portion 31 and the inner wall of the suction cup connecting portion 21. The clamping structure 4 includes a clamping groove 41 provided on the outer wall of the mounting portion 31 and a clamping protrusion 42 provided on the inner wall of the suction cup connecting portion 21 and clamped with the clamping groove 41.

[0035] In order to facilitate disassembly and assembly, a quick-installation structure 5 for quickly installing the suction cup body 2 on the mounting frame 1 is provided between the suction cup body 2 and the mounting frame 1. The quick-installation structure 5 includes a quick-installation convex ring 51 provided on the outer wall of the suction cup body 2 and a quick-installation buckle 52 provided on the mounting frame 1 and snap-fitted with the quick-installation convex ring 51.

[0036] like Figure 1 As shown, the quick-install undercut 52 or the mounting frame 1 is provided with a strip-shaped through hole / groove 521 which can facilitate the quick-install undercut 52 to undergo corresponding deformation.

[0037] like Figure 2 , 3 As shown in FIGS. 5 and 6, in order to prevent the suction cup from being crushed due to overpressure, the mounting frame 1 is provided with a protective pad 10 on one side of the suction cup body 2, which can contact the contact surface when the suction cup body 2 cooperates with the contact surface. The protective pad 10 can be made of plastic, silicone, rubber and other materials. In some embodiments, the protective pad 10 can be formed on the mounting frame 1 by secondary injection molding with an elastomeric material, or can be pasted on the mounting frame 1 with a foam elastic pad adhesive.

[0038] Embodiment 2:

[0039] The difference between Example 2 and Example 1 is that Figure 7 As shown, in order to reduce the number of assembly steps and ensure the connection strength, the deformable member 3 and the suction cup body 2 are integrally formed by elastically deformable material.
