DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] refer to Figure 1-5 The utility model provides a technical solution: it includes a heat preservation pot body 1, a threaded ring 2 is fixedly connected to the top of the heat preservation pot body 1, a pot cover 3 is sealed and connected to the top of the heat preservation pot body 1, a threaded groove 7 is provided on the lower end surface of the pot cover 3, the threaded ring 2 is threadedly connected in the threaded groove 7, and a vent 4 is provided on the upper end surface of the pot cover 3. By setting the vent 4, the heat preservation pot body 1 can be connected to the atmosphere through the vent 4, so that the air pressure is equal and it is convenient for the user to open the pot cover 3. A limiting groove 11 is provided in the pot cover 3, a sliding groove 5 is provided on the upper end surface of the pot cover 3, a sealing ring body 10 is provided in the threaded groove 7, the top of the threaded ring 2 is sealed and connected to the lower end surface of the sealing ring body 10, a sealing block 8 is slidably connected in the limiting groove 11, and a spring 9 is fixedly connected in the limiting groove 11. By setting the spring 9, the sealing block 8 can be pressed between the vents 4 by the elastic force of the spring 9 itself, one end of the spring 9 is fixedly connected to the front of the sealing block 8, and the upper end surface of the sealing block 8 is fixedly connected with a connecting rod 12.

[0022] The shape of the sealing block 8 matches the shape of the limiting groove 11 , and the diameter of the connecting rod 12 matches the width of the sliding groove 5 .

[0023] The vent hole 4 is connected to the inside of the thermos pot body 1 , and the vent hole 4 is also connected to the inside of the limiting groove 11 .

[0024] The slide groove 5 is connected to the limiting groove 11 , and the lower end surface of the shifting block 6 is slidably connected to the upper end surface of the pot cover 3 .

[0025] Among them, the top end of the connecting rod 12 is fixedly connected with a shift block 6. By setting the shift block 6, the user can drive the sealing block 8 to move forward through the shift block 6, so that the vent hole 4 is connected with the thermos pot body 1, and the air pressure in the thermos pot body 1 can be equal to the atmospheric pressure. The surface of the connecting rod 12 is slidably connected in the slide groove 5.

[0026] The shape of the thread ring 2 matches the shape of the thread groove 7 , and the shape of the sealing ring body 10 matches the shape of the thread ring 2 .

[0027] The working principle of the utility model is as follows: when using the device, the user can add boiling water into the thermos pot body 1, and then the user tightens the pot cover 3 on the threaded ring 2, which can increase the insulation time of the boiling water by the device. After the pot cover 3 is not opened for a long time to cool down the boiling water, the volume of the hot air in the thermos pot body 1 is reduced after cooling down, which will cause the air pressure in the thermos pot body 1 to be lower than the atmospheric pressure, making it difficult to open the pot cover 3. The user only needs to push the push block 6 forward, and the push block 6 drives the sealing block 8 to move forward through the connecting rod 12, so that the vent 4 can be connected with the thermos pot body 1. At this time, the outside air enters the thermos pot body 1, and the user can open the pot cover 3 smoothly.
