[0014] Implementing the embodiments of this utility model will have the following beneficial effects:
[0015] In this utility model, the cooking device includes a pot lid assembly and a float valve. The pot lid assembly has a first through hole, and the float valve is disposed in the first through hole. The float valve includes a valve seat and a float structure. The valve seat has a valve cavity. The upper and lower end walls of the valve cavity are respectively provided with a first vent hole and a second vent hole. The first vent hole, the valve cavity, and the second vent hole are connected to form an exhaust channel. The float structure is moved up and down in the valve cavity to abut or disengage from the lower end wall of the second vent hole, thereby closing or opening the exhaust channel. The float structure extends or retracts in the first through hole. When there is pressure inside the pot, the high-pressure gas flow enters the valve cavity through the first vent and impacts the float structure, causing it to move upward and abut against the lower wall of the second vent, sealing the second vent and closing the venting channel. At this time, the float structure extends from the first perforation, alerting the user that there is pressure inside the pot and preventing the user from opening the lid assembly before the pressure is fully released, which could lead to potential hazards. When it is necessary to accelerate venting, the float structure is pressed, causing it to move downward and disengage from the lower wall of the second vent, allowing the high-pressure gas entering the valve cavity to escape through the second vent, thus opening the venting channel. Once the high-pressure gas inside the pot has been completely released, the float structure falls onto the bottom wall of the valve cavity under its own weight, at which point it retracts into the first perforation. This float valve can be used for both venting and depressurizing, as well as to indicate to the user whether there is still pressure inside the pot, thus achieving multiple functions.

[0027] See Figures 1-4 This utility model provides a cooking device, including a pot lid assembly 2 and a float valve. The pot lid assembly 2 has a first through hole, and the float valve is disposed in the first through hole. The float valve includes a valve seat 1 and a float structure 3. The valve seat 1 has a valve cavity 11. The upper and lower end walls of the valve cavity 11 are respectively provided with a first vent hole 121 and a second vent hole 131. The first vent hole 121, the valve cavity 11 and the second vent hole 131 are connected to form an exhaust channel. The float structure 3 is moved up and down in the valve cavity 11 to abut or disengage from the lower end wall of the second vent hole 131 to close or open the exhaust channel. The float structure 3 extends or retracts in the first through hole. When there is pressure inside the pot, the high-pressure gas flow enters the valve chamber 11 through the first vent 121 and impacts the float structure 3, causing the float structure 3 to move upward and abut against the lower end wall of the second vent 131, sealing the second vent 131 and closing the venting channel. At this time, the float structure 3 extends out from the first perforation, alerting the user that there is pressure inside the pot and preventing the user from opening the pot lid assembly 2 before the pressure is completely released, which could lead to potential hazards. When it is necessary to accelerate the venting, the float structure 3 is pressed, causing it to move downward and disengage from the lower end wall of the second vent 131, allowing the high-pressure gas entering the valve chamber 11 to be discharged from the second vent 131, thus opening the venting channel. When the high-pressure gas inside the pot is completely discharged, the float structure 3 falls onto the bottom wall of the valve chamber 11 under its own weight, at which point the float structure 3 retracts into the first perforation. The float valve of this invention can be used for both venting and depressurizing, as well as for alerting the user whether there is still pressure inside the pot, thus achieving multiple functions.
[0028] Furthermore, the float structure 3 includes a float body and a guide post 35 disposed on the float body. The float body is located within the valve cavity 11, and the guide post 35 penetrates the second vent hole 131. The guide post 35 extends out of or retracts within the first through hole. Specifically, the diameter of the guide post 35 is smaller than the aperture of the second vent hole 131, and the distance between the outer wall of the guide post 35 and the inner wall of the second vent hole 131 is greater than 0.5 mm, allowing gas in the valve cavity 11 to be smoothly discharged from the second vent hole 131.
[0029] Furthermore, the float body includes a float connecting part 31 and a blocking part 32, the blocking part 32 is arranged around the float connecting part 31, and the guide post 35 is arranged on the top wall of the float connecting part 31.
[0030] Furthermore, the upper end of the guide post 35 is provided with a float cap 34. When the float structure 3 moves downward to a preset position, the float cap 34 retracts into the first through hole; when the float structure 3 moves away from the preset position, the float cap 34 extends out of the first through hole. The preset position is the lowest position after the float structure 3 moves downward. When there is no pressure in the pot, the float structure 3 falls to the lowest position under its own weight, at which time the float cap 34 retracts into the first through hole; when there is pressure in the pot, the pressure in the pot will impact the float structure 3, causing the float structure 3 to move upward away from the lowest position, at which time the float cap 34 extends out of the first through hole. By observing the state of the float cap 34, the user can intuitively judge whether there is pressure in the pot, avoiding the user opening the pot lid assembly 2 when there is pressure in the pot, which may cause hidden dangers.
[0031] Furthermore, the blocking part 32 includes a blocking part body 321, a first directional section 322 disposed at the upper end of the blocking part body 321, and a second directional section 323 disposed at the lower end of the blocking part body 321. The first directional section 322 and the second directional section 323 protrude from the upper and lower end walls of the float connecting part 31, respectively. The first directional section 322 is provided with at least one first venting notch 324, and the second directional section 323 is provided with at least one second venting notch 325. By designing the first venting notch 324 and the second venting notch 325, the high-pressure gas in the pot can quickly pass through the venting gap between the blocking part 32 and the inner wall of the valve chamber 11 after entering the valve chamber 11, and then be discharged to the outside from the second exhaust port 131, so that the pressure in the pot is rapidly reduced, achieving the effect of rapid pressure reduction.
[0032] Furthermore, there are multiple second venting gaps 325, which are circumferentially spaced on the sidewall of the second section 323 to form a serrated structure at the end of the second section 323; there are also multiple first venting gaps 324, which are circumferentially spaced on the sidewall of the first section 322 to form a serrated structure at the end of the first section 322, with each first venting gap 324 corresponding to one second venting gap 325. This facilitates the faster passage of high-pressure gas through the venting gap between the baffle 32 and the inner sidewall of the valve chamber 11, further accelerating the pressure relief of the pressure cooker.
[0033] Furthermore, the cooking device includes a sealing gasket 4. A sealing mounting portion 33 is formed between the first section 322 and the guide post 35. The sealing gasket 4 is sleeved on the guide post 35 and located within the sealing mounting portion 33. The sealing gasket 4 is used to abut against the lower end wall of the second vent 131 to seal the second vent 131. Specifically, the sealing gasket 4 is an annular gasket, and the outer diameter of the sealing gasket 4 is larger than the diameter of the second vent 131. The sealing gasket 4 is fixedly connected to the top wall of the float connecting portion 31. Specifically, it can be embedded in the sealing mounting portion 33, with the annular gasket clamped between the inner side wall of the first section 322 and the outer side wall of the guide post 35; or it can be fixed by adhesive to the top wall of the float connecting portion 31.
[0034] Furthermore, the valve seat 1 includes a valve seat body 12 and a valve core 13. The valve seat body 12 has an opening, and the valve core 13 covers the opening to form the valve cavity 11. The first vent hole 121 is provided on the valve seat body 12, and the second vent hole 131 is provided on the valve core 13.
[0035] Furthermore, the valve core 13 includes a valve core body and a valve core connecting part 133. The valve core connecting part 133 is disposed on the outer periphery of the valve core body. The bottom wall of the valve core body is provided with a boss 132 extending into the valve cavity 11. The boss 132 is disposed around the second exhaust hole 131. The float structure 3 can abut against the bottom wall of the boss 132 to seal the second exhaust hole 131.
[0036] Furthermore, the pot lid assembly 2 includes an inner liner 21 and an upper shell 22. The upper shell 22 covers the inner liner 21 and forms an installation cavity. The float valve is installed in the installation cavity. The inner liner 21 is provided with a first through hole 211, and the upper shell 22 is provided with a second through hole 221. The bottom wall of the valve core connecting part 133 is pressed against the top wall of the inner liner 21. The first through hole 211 and the second through hole 221 together form the first through hole.
[0037] Furthermore, the cooking device also includes a sealing ring 5, which is disposed on the top wall of the valve seat body 12. The top of the sealing ring 5 abuts against the bottom wall of the inner liner 21, and the inner peripheral wall of the sealing ring 5 abuts against the outer peripheral wall of the valve core body. The sealing ring 5 simultaneously achieves a sealed connection between the valve seat body 12, the inner liner 21, and the valve core body, preventing high-pressure gas inside the pot from escaping through the connection gaps into the pot lid and damaging the internal components of the pot lid.
[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit the scope of protection of the utility model.
