Technical Field
[0001] The utility model relates to a bottle stopper, in particular to an automatic pressure-releasing thermal insulation bottle stopper. Background Art
[0002] For thermos, the commonly used bottle stoppers are corks or plastic bottle stoppers. When using the corks of thermos, the steam in the thermos often fumigates for a long time, which often causes the corks to burn people's hands when opening the bottle.
[0003] In addition, when the bottle is filled with hot water, as the steam pressure in the bottle increases, the cork may sometimes jump out due to a loose fit between the cork and the bottle body, making it impossible to keep warm. At the same time, after the cork is removed, it is easily contaminated by the table when placed on the table, which is extremely unhygienic. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide an automatic pressure-releasing thermos bottle plug.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is an automatic pressure relief thermos bottle stopper, comprising a bottle stopper, a pull ring, a lower valve body, an upper valve body, a plug, a connector, a connecting rod, a connecting rod, a stopper, and a spring. The bottle stopper comprises a lower cylinder and an upper hemispherical body. The bottle stopper is provided with a No. 1 pressure relief hole that penetrates the body in a vertical direction. The cylinder is provided with a lower valve body, the hemispherical body is provided with an upper valve body, the upper valve body is threadedly connected to the lower valve body, and the lower valve body is provided with a No. 2 pressure relief hole;
[0006] A pressure relief chamber is provided in the upper valve body, a plug is provided in the upper valve body which can block the No. 2 pressure relief hole, a connecting rod is provided on the upper part of the plug, a connecting piece and a limiting piece are provided on the connecting rod, the lower part of the connecting piece is threadedly connected to the plug, connecting holes are correspondingly provided on the limiting piece and the connecting rod, and the connecting rod passes through the connecting hole to connect the limiting piece and the connecting rod to form a connecting structure;
[0007] A spring is also sleeved on the connecting rod, the lower part of the spring abuts against the top of the limiting member, and the top of the spring abuts against the valve body at the top of the pressure relief chamber.
[0008] Furthermore, the cylinder and the hemisphere are an integrally formed structure.
[0009] Furthermore, a pull ring for fixed connection is provided at the top end of the connecting rod.
[0010] Furthermore, the cylinder is a variable diameter cylinder, and its radius gradually decreases from top to bottom.
[0011] Furthermore, an annular groove is provided on the circumference of the outer wall of the cylinder.
[0012] Furthermore, the No. 1 pressure relief hole, No. 2 pressure relief hole, and the pressure relief cavity are arranged correspondingly.
[0013] Furthermore, the cylinder and the hemisphere are both made of silicone.
[0014] Compared with the prior art, the advantages of the utility model are: the device has a reasonable structural design and is easy to use. The bottle plug includes a lower cylinder and an upper hemisphere, and the hemisphere is heavy and the cylinder is light. The overall configuration is a tumbler design. When placed on a desktop, the cylinder will not directly contact the desktop to avoid contamination. When the pressure in the thermos bottle is relatively large, the plug is lifted up, and the pressure in the thermos bottle will be released through the No. 1 pressure relief hole, the No. 2 pressure relief hole, and the pressure relief cavity in sequence. After the pressure in the thermos bottle is released, because a spring is provided on the connecting rod, under the action of the spring, the connecting rod pushes the plug to seal the No. 2 pressure relief hole. In addition, in order to avoid the situation where negative pressure in the bottle is caused by the decrease in water temperature in the thermos bottle, which makes it inconvenient to open the bottle plug, the device is also provided with a pull ring, through which the connecting rod can be manually pulled upward to lift the plug, so that the inside and outside of the bottle are connected, and the bottle plug is convenient to pull out after the pressure inside and outside the screen is consistent.
