Abstract
Description
Technical Field
[0001] The utility model relates to the structural improvement of a gas pressure relief valve, and a heating container adopting the gas pressure relief valve.
Background Art
[0002] Traditional gas pressure relief valves are composed of multiple components, with a relatively complex structure and not conducive to cost savings.
Content of the Utility Model
[0003] The utility model aims to provide a gas pressure relief valve with a simpler structure. For this purpose, the utility model adopts the following technical solutions:
[0004] A flexible pressure relief valve, which is an umbrella-shaped silica gel valve body, including an elastic umbrella handle part and an umbrella cover part integrally formed at the top of the elastic umbrella handle part. A plurality of radial clamping strips and a plurality of axial air guide grooves are annularly arranged on the outer peripheral wall of the elastic umbrella handle part.
[0005] As a preferred scheme, the plurality of radial clamping strips and the plurality of axial air guide grooves are evenly and alternately arranged on the outer peripheral wall of the elastic umbrella handle part.
[0006] As a preferred scheme, the plurality of axial air guide grooves communicate with the bottom end of the elastic umbrella handle part and the bottom surface of the umbrella cover part.
[0007] As a preferred scheme, the plurality of radial clamping strips are arranged at the bottom of the elastic umbrella handle part.
[0008] As a preferred scheme, a retracted blind hole is provided on the bottom surface of the elastic umbrella handle part, and the plurality of radial clamping strips are arranged around the retracted blind hole.
[0009] The elastic umbrella handle part of the above flexible pressure relief valve has elasticity. When contracting, it can pull the umbrella cover part downward to close the pressure relief hole. When stretching, the umbrella cover part can rise to open the pressure relief hole. This flexible pressure relief valve has only one component, and compared with traditional gas pressure relief valves, it has the advantages of simple structure and low cost.
[0010] The utility model also discloses a heating container adopting the above flexible pressure relief valve, and its technical solution is as follows:
[0011] The heating container includes a heating cup with an open top and a cup cover fixedly covered on the top of the heating cup to close its top opening. The heating cup is connected with a heating device. A pressure relief hole is provided on the top of the cup cover. The elastic umbrella handle part is arranged in the pressure relief hole so that the umbrella cover part closes the top opening of the pressure relief hole from above the cup cover. Four radial clamping strips are clamped outside the bottom opening of the pressure relief hole to fix the flexible pressure relief valve at the pressure relief hole.

Specific implementation manner
[0015] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Refer to Figures 1-3 :
[0017] A heating container 10 includes a heating cup 11 with an open top and a cup lid 12 fixedly covered on the top of the heating cup 11 to close its top opening. The heating cup 11 is connected with a heating device. A pressure relief hole 12.1 is provided on the top of the cup lid 12, and a flexible pressure relief valve 20 is arranged in the pressure relief hole 12.1.
[0018] The flexible pressure relief valve 20 is an umbrella-shaped silica gel valve body, including an elastic umbrella handle part 21 and an umbrella cover part 22 integrally formed at the top end of the elastic umbrella handle part 21. An inwardly retracted blind hole 21.1 is provided on the bottom surface of the elastic umbrella handle part 21. Four radial clamping strips 21.2 are integrally formed and evenly annularly arranged on the outer peripheral wall of the elastic umbrella handle part 21 outside the inwardly retracted blind hole 21.1. Four axial steam guiding grooves 21.3 communicating the bottom end of the elastic umbrella handle part 21 and the bottom surface of the umbrella cover part 22 are also evenly annularly arranged on the outer wall of the elastic umbrella handle part 21. The four axial steam guiding grooves 21.3 and the four radial clamping strips 21.2 are alternately arranged.
[0019] The elastic umbrella handle part 21 is arranged in the pressure relief hole 12.1 so that the umbrella cover part 22 closes the top opening of the pressure relief hole 12.1 from above the cup lid 12. The four radial clamping strips 21.2 are clamped outside the bottom opening of the pressure relief hole 12.1 to fix the flexible pressure relief valve 20 at the pressure relief hole 12.1.
[0020] During installation, the four clamping strips 21.2 are bent downward and brought together and then inserted into the pressure relief hole 12.1 from the top opening. Due to the provision of the inwardly retracted blind hole 21.1 to provide a retreat space, the four clamping strips 21.2 can pass through the pressure relief hole 12.1 and expose outside the bottom opening of the pressure relief hole 12.1 and expand, cooperating with the umbrella cover part 22 exposed outside the top opening of the pressure relief hole 12.1 up and down to seal the pressure relief hole 12.1.
[0021] During use, when the water in the heating cup 11 is heated and the air pressure in the cup rises to a certain value, the high-pressure gas in the cup can drive the umbrella cover part 22 upward along the four axial steam guiding grooves 21.3, and then drive the elastic umbrella handle part 21 to stretch. The umbrella cover part 22 can rise to open the pressure relief hole 12.1, and the high-pressure gas in the cup can be discharged outward.
