AI Technical Summary
Self-inflating products are prone to back-inflating during storage, making them difficult to store. Existing valve core flipping requires users to insert their fingers into the valve, which is difficult to achieve.
A valve is designed such that a protrusion is set on the support plate of the valve core, and the user can flip the valve core by moving the protrusion outside the valve port. Combined with the limiting structure and the sealing structure, a one-way sealing effect is ensured.
It enables convenient valve core flipping and valve miniaturization, reduces structural complexity, and improves service life and sealing effect.

Abstract
Claims
1. A valve, characterized in that The valve includes: Valve seat, wherein the valve seat is provided with a fluid passage; The valve core includes a support disk and a one-way diaphragm. The support disk is rotatably mounted in the fluid channel. The support disk has a protrusion on at least one surface and a through hole. The one-way diaphragm is mounted on the support disk and covers the through hole.
2. The valve of claim 1, wherein The protrusion includes a connecting part and a toggle part. One end of the connecting part is connected to the support plate, and the toggle part is connected to the other end of the connecting part. The connection position between the connecting part and the support plate is located at the edge of the support plate.
3. The valve of claim 2, wherein The actuating part extends from the end away from the connecting part toward the center of the fluid channel.
4. The valve of claim 2, wherein The connecting part includes a first connecting part and a second connecting part, the first connecting part and the second connecting part are respectively connected to the edge of the bracket plate, and the actuating part is respectively connected to the first connecting part and the second connecting part.
5. The valve of claim 1, wherein The protrusions are provided on both surfaces of the support plate.
6. The valve according to any one of claims 1 to 5, characterized in that, The protrusion and the support plate are integrally formed; or The protrusion and the support plate are detachably connected; or The protrusion includes a connecting part and a toggle part. The connecting part includes a connecting ring plate and a connecting block connected to the connecting ring plate. The connecting ring plate is fixedly connected to the support plate, and the toggle part is connected to the connecting block.
7. The valve according to any one of claims 1 to 5, characterized in that The support plate includes a first support plate and a second support plate, both of which are provided with the through hole. The first support plate and the second support plate are detachably connected, and the unidirectional diaphragm is disposed between the first support plate and the second support plate.
8. The valve according to any one of claims 1 to 5, characterized in that The sidewall of the fluid channel and the support plate are provided with a mutually cooperating limiting structure to limit the valve core and maintain the unidirectional closure of the fluid channel.
9. The valve according to any one of claims 1 to 5, characterized in that The valve also includes a valve cover, which is detachably connected to the valve seat. The valve cover includes an abutment portion located on the side near the valve seat. When the valve cover closes the fluid passage, the abutment portion abuts against the support plate.
10. The valve according to any one of claims 1 to 5, characterized in that, The valve also includes a valve cover, which includes a limiting member extending to the fluid channel. The limiting member includes a first limiting surface and the protrusion includes a second limiting surface. When the valve cover closes the fluid channel, the first limiting surface and the second limiting surface are in contact.
11. The valve of claim 10, wherein The protrusion includes a connecting portion and a pushing portion. The connecting portion includes a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are respectively connected to the edge of the support plate. The pushing portion is respectively connected to the first connecting portion and the second connecting portion. The second limiting surface is close to the side wall of the fluid channel and is an arc surface. The limiting member is cylindrical. The first limiting surface is located inside the limiting member and is spherical.
12. The valve according to any one of claims 1 to 5, characterized in that The distance between the unidirectional diaphragm and the rotating axis of the support disk is no greater than 5mm.
13. The valve of any one of claims 1 to 5, wherein, A sealing structure is provided between the support plate and the valve seat.
14. The valve of claim 13, wherein The side wall of the support plate is provided with an annular groove. The sealing structure includes a sealing ring. The sealing ring includes a sleeve portion and a first sealing thin plate ring and a second sealing thin plate ring connected to the sleeve portion. The sleeve portion is disposed in the annular groove. The first sealing thin plate ring and the second sealing thin plate ring are spaced apart along the central axis of the sleeve portion. The first sealing thin plate ring and the second sealing thin plate ring are interference-fitted with the valve seat.
15. An aerated product characterised in that, The inflatable product includes a body and a valve of any one of claims 1 to 14 mounted on the body, wherein the outer side of the valve seat of the valve is connected to the body.
