[0002] As an indispensable household item in people's daily life, the thermos flask has a very high usage frequency. However, during long-term use, activities such as making tea and coffee often cause scale and stains to remain inside the flask lid, which not only affects the hygiene of the lid but also poses a potential threat to the user's physical health. In addition, since thermos flasks usually have good sealing performance, when the flask is filled with hot water, a relatively high-pressure environment will be formed. In this case, if the user directly presses the water outlet button, the hot water and gas in the flask may spray out simultaneously, easily causing scalds to the user. Even more seriously, when the user tries to open the flask lid when the flask is filled with hot water, the high-temperature air pressure may splash out together with the hot water, causing injury to the user. Sometimes, just because of the high-pressure environment inside the flask, the user may also encounter noises and the flask lid jumping upwards when opening the lid, which not only affects the user experience but may also cause accidental injuries.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a detachable and cleanable air-releasable heat-insulating kettle lid, as Figures 1-4 shown, including a cover body 18, a water outlet body 9, and a water blocking valve body 19. The cover body 18 is slidably matched with the water outlet body 9 to form a water outlet channel. A space is provided at the bottom of the water outlet body 9 for installing the water blocking valve body 19. A linkage body 6 is installed inside the cover body 18. The water blocking valve body 19 includes a water blocking valve piece 17 and a valve core 13 for controlling the outflow of water and the release of gas. A small hole is provided inside the water blocking valve piece 17 for gas circulation to achieve the function of pressure release.

[0025] In this embodiment, a linkage body cover 5 is installed on the top of the linkage body 6. The cover body 18 includes an upper cover 1 and a lower cover 8. Buttons are installed on the upper cover 1. The buttons include a first button 2 and a second button 3, which are respectively used for pouring water and relieving pressure when opening the kettle lid. The buttons cooperate with the linkage body 6 and trigger the pressure relief mechanism by moving downward. The second button 3 is symmetrically arranged in two on the lower part of the first button 2.

[0026] Specifically, a first spring 4 is arranged between the two sides of the second button 3 and the linkage body cover 5, a second spring 7 is arranged between the linkage body 6 and the lower cover 8, and a third spring 12 is arranged between the valve cap 11 and the water blocking valve piece 17, which is used to provide elastic force to reset the water blocking valve piece after pressure relief.

[0027] Furthermore, the linkage body 6 has a lug structure for clamping with the water blocking valve body 19. The water blocking valve body 19 is fixed by rotating and clamping with the lug structure.

[0028] Furthermore, a guide rail 181 is arranged on the outside of the cover body 18, and a guide rail groove 91 is arranged on the inside of the water outlet body 9. The guide rail 181 is in sliding fit with the guide rail groove 91.

[0029] Furthermore, an air vent is arranged on the back of the water outlet body 9. After the water blocking valve piece 17 is pressed, the valve core 13 moves downward. After the gas enters, it passes through the small holes inside the water blocking valve piece 17 and then through the air vent on the back of the water outlet body 9. After pressure relief, the third spring 12 provides elastic force to reset the water blocking valve piece 17.

[0030] Furthermore, the linkage body 6 connects the button and the water blocking valve body 19, transmits the movement of the button, and realizes the cooperative pressure relief opening and closing movement among the water blocking valve piece 17, the valve core 13, and the third spring 12 under pressure.

[0031] Furthermore, a first silica gel 10 is installed on the outside of the water outlet body 9. Second silica gel 14, third silica gel 15, and fourth silica gel 16 are arranged between the valve core 13 and the water blocking valve piece 17. A valve cap 11 is installed at the end of the valve core 13.

[0032] When the detachable and cleanable air - releasable thermal insulation kettle lid of the present utility model is in use, when the user needs to pour water, the first button 2 is pressed. This button cooperates with the head of the linkage body 6, triggering its downward movement. The linkage body 6 is assembled and clamped with the valve core 13, so the entire water - blocking valve body 19 will also move downward accordingly. In a high - pressure environment, the area of the water - blocking valve piece 17 in contact with the air pressure is large, and the resistance it receives is also large; while the contact area of the valve core 13 is small, and the resistance it receives is relatively small. Therefore, the valve core 13 will open first. The downward movement of the valve core 13 will compress the third spring 12, and a gap will appear between the valve core 13 and the water - blocking valve piece 17, and the gas will flow in through the gap. There are small holes inside the water - blocking valve piece 17, and after the gas enters through the small holes, it flows to the outside through the air - release port provided on the back of the water - outlet main body 9, thus realizing the air - release and pressure - relief function. When the air pressure is released, the internal pressure of the kettle becomes smaller, the resistance received by the water - blocking valve piece 17 becomes smaller, and the third spring 12 rebounds to make the water - blocking valve piece 17 move downward, opening the water outlet to avoid splashing when pouring water.

[0033] When the user needs to open the kettle lid under a high - pressure environment inside the kettle, the second button 3 is pressed. The second button 3 contracts inward, and the sliding arc at its bottom contacts the four sliding arcs of the linkage body 6, causing the linkage body 6 to move downward. Similarly, the linkage body 6 is assembled and clamped with the valve core 13, and the entire water - blocking valve body 19 will also move downward. In a high - pressure environment, the area of the water - blocking valve piece 17 in contact with the air pressure is large and the resistance it receives is large; while the contact area of the valve core 13 is small and the resistance it receives is small, so the valve core 13 will open first. The downward movement of the valve core 13 compresses the third spring 12, exposing a gap for the gas to flow in. The gas enters through the small holes of the water - blocking valve piece 17 and then flows to the outside through the air - release port of the water - outlet main body 9, realizing the air - release and pressure - relief function. This can avoid the noise and the lid jumping when opening the kettle lid.

[0034] During this process, the first spring 4 provided between the second button 3 and both sides of the linkage body cover 5 provides a restoring force; the second spring 7 provided between the linkage body 6 and the lower cover 8 also provides a restoring force; and the third spring 12 provided between the water - blocking valve body 19 and the cover main body 18 is used for the reset of the water - blocking valve piece 17 and the realization of the pressure - relief function.

[0035] In addition, a guide rail 181 is provided on the inner side of the cover main body 18, and a guide rail groove 91 is provided on the inner side of the water - outlet main body 9. The guide rail 181 and the guide rail groove 91 are in sliding fit, ensuring the stability and smoothness of the water - outlet main body 9 during the opening and closing processes. A first silica gel 10 is installed on the outer side of the water - outlet main body 9, providing good sealing performance; second silica gel 14, third silica gel 15, and fourth silica gel 16 are provided between the valve core 13 and the water - blocking valve piece 17, ensuring the durability and reliability of the water - blocking valve body 19 during long - term use; a valve cap 11 is installed at the end of the valve core 13 to prevent external damage.

[0036] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
