Detailed implementation manners

[0039] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] Please refer to Figure 1 , a pressure cooking appliance 100 provided by the embodiment of the present application. The pressure cooking appliance 100 is a kitchen cooking tool, including a pot body 20 and a lid assembly 10.

[0041] The pot body 20 is the main part of the pressure cooking appliance 100, usually made of high-pressure-resistant metal materials such as stainless steel or aluminum alloy. A cooking space is formed inside the pot body 20 for accommodating food and water. The top of the pot body 20 has an opening. The circumferential side wall of the pot body 20 protrudes outward with pot teeth 201, and a plurality of pot teeth 201 are arranged at intervals along the circumferential direction of the pot body 20. The pot teeth 201 are located at the opening of the pot body 20.

[0042] The lid assembly 10 is used to cover the opening of the pot body 20, so that the lid assembly 10 and the pot body 20 are closely matched to form a sealed cooking space. The lid assembly 10 has a protection structure. The protection structure can lock the lid assembly 10 and the pot body 20 when there is pressure inside the pot body 20, preventing the user from forcibly opening the lid assembly 10 when there is pressure in the pot, and playing a role in preventing the user from being scalded by high temperature.

[0043] Please refer to Figure 2 and Figure 3 , a lid assembly 10 provided by the embodiment of the present application. The lid assembly 10 includes a lid body 1, a locking member 3, a float 2 and a protection structure.

[0044] The lid body 1 is usually made of the aluminum alloy material of the pressure cooking appliance 100 by casting. The lid body 1 can be covered on the opening of the pot body 20, so that the lid body 1 can open or close the pot body 20. When the lid body 1 closes the pot body 20, the lid body 1 can form a sealed cooking space with the pot body 20.

[0045] Optionally, a sealing ring is usually provided between the lid body 1 and the pot body 20, which can increase the sealing performance and prevent the pressure inside the pot body 20 from leaking.

[0046] Combined Figures 4 to 6 As shown, the locking member 3 is movably arranged on the lid body 1 in the horizontal direction, so that the locking member 3 can move horizontally relative to the lid body 1. One end of the locking member 3 is located above the lid body 1, and a limiting portion 7 can be provided at one end of the locking member 3. The other end of the locking member 3 is located on the periphery of the lid body 1, and a self-locking portion 8 is provided at the other end of the locking member 3. The self-locking portion 8 can be arranged opposite to the pot body 20, and the self-locking portion 8 can cooperate with the pot teeth 201 on the pot body 20 to lock the lid body 1 and the pot body 20, so that the user cannot open the pressure cooking appliance 100, preventing the user from opening the pressure cooking appliance 100 when there is pressure in the pot and causing the user to be scalded.

[0047] The float 2 can be movably arranged on the lid body 1 in the vertical direction, so that the float 2 can float up and down relative to the lid body 1, and the float 2 can switch between the floating position and the sinking position. In this embodiment, a float seat is provided on the lid body 1, and the float 2 is movably arranged on the float seat, so that the float 2 can float up and down.

[0048] Combined Figure 7 When there is pressure inside the pot body 20, it will drive the float 2 to float upward to the floating position. The float 2 at the floating position can cooperate with the limiting portion 7 to limit the freedom of horizontal movement of the locking member 3, or in other words, make the locking member 3 unable to move in the horizontal direction. At this time, the self-locking portion 8 is located in the groove between two adjacent pot teeth 201, and the self-locking portion 8 abuts against the pot teeth 201. Since the horizontal movement freedom of the locking member 3 is limited by the float 2, the self-locking portion 8 cannot be separated from the abutting state with the pot teeth 201, so that the self-locking portion 8 can lock the lid body 1 and the pot body 20. Therefore, when there is pressure inside the pot body 20, the user cannot open the lid body 1, which can prevent the user from being injured by high temperature.

[0049] Combined Figure 6, when there is no pressure inside the pot body 20, the float 2 will fall to the sinking position due to its own gravity. When the float 2 is in the sinking position, it will be disengaged from the limiting part 7, enabling the locking member 3 to move freely in the horizontal direction. When the user needs to open the pot lid body 1, the user can rotate the pot lid body 1. Since the locking member 3 can move freely in the horizontal direction, during the rotation of the pot lid body 1, the self-locking part 8 can move along the pot teeth 201, so that the user can rotate the pot lid body 1 relative to the pot body 20, thereby opening the pot lid body 1.

[0050] However, some users will try to press down the float 2 and forcefully open the pot lid body 1 when there is pressure inside the pot, resulting in self-injury from high temperature. The protection structure is arranged above the float 2, and the protection structure can prevent the user from forcefully opening the pot lid body 1 when there is pressure inside the pot, playing a protective role. And during a long cooking process, viscous liquid will adhere to the surface of the float 2, causing the float 2 to fail to fall normally. Through the protection structure, the float 2 can be easily driven to move, and the viscous liquid on the surface can be removed during the movement of the float 2, enabling the float 2 to float up and down normally relative to the pot lid body 1.

[0051] Please refer to Figure 2 and Figure 3 , a protection structure provided by an embodiment of the present application. The protection structure includes a float cover 4. The float cover 4 can be arranged above the float 2, and a stop-opening convex block 401 is provided on the side of the float cover 4 facing the locking member 3. The float cover 4 is movably installed on the pot lid body 1, enabling the float cover 4 to move relative to the pot lid body 1 and switch between a limiting position and an avoidance position. Optionally, the float cover 4 can be slidably connected to the pot lid body 1.

[0052] Combined with Figures 7 to 9 , specifically, when the float 2 is adhered to the pot lid body 1 due to the attached viscous liquid, resulting in the float 2 being unable to float up and down relative to the pot lid body 1, the user can press the float cover 4 downward by hand to the limiting position. At this time, the float cover 4 can drive the float 2 to fall to the sinking position, and the viscous liquid on the surface can be removed during the movement of the float 2, enabling the float 2 to float up and down normally relative to the pot lid body 1.

[0053] In addition, combined with Figure 9 , when the float cover 4 is in the limiting position, the stop-opening convex block 401 can cooperate with the locking member 3, making the locking member 3 unable to move in the horizontal direction. Thus, the self-locking part 8 on the locking member 3 can cooperate with the pot teeth 201 to lock the pot lid body 1 and the pot body 20.

[0054] Combined with Figure 7, when the float cover 4 is in the avoidance position, there is a gap between the float cover 4 and the float 2 in the vertical direction, so that the float cover 4 will not interfere with the float 2, or in other words, when the float cover 4 is in the avoidance position, it will not affect the normal up and down floating of the float 2.

[0055] Therefore, by setting the float cover 4, the float 2 can be easily driven to move. And when the float cover 4 drives the float 2 to move downward to the sinking position, although the float 2 loses the function of limiting the locking member 3, or in other words, the float 2 no longer functions to lock the pot cover body 1, but the anti-opening convex block 401 on the float cover 4 can cooperate with the locking member 3, so that the locking member 3 locks the pot cover body 1. Thus, the float cover 4 can prevent the user from forcibly opening the pot cover body 1 when there is pressure in the pot, playing a protective role.

[0056] Combined with Figures 7 to 9 , in some embodiments, when the float cover 4 is in the limiting position, it will drive the float 2 to disengage from the limiting portion 7, and the anti-opening convex block 401 can cooperate with the limiting portion 7, so that the locking member 3 cannot move horizontally. Thus, the anti-opening convex block 401 and the float 2 can alternately cooperate with the limiting portion 7, so that setting a limiting portion 7 on the locking member 3 can meet the requirements.

[0057] Of course, in some other embodiments, the locking member 3 can also be provided with an anti-opening concave portion, which is adapted to the anti-opening convex block 401. When the float cover 4 is in the limiting position, the anti-opening convex block 401 can cooperate with the anti-opening concave portion, so that the locking member 3 cannot move horizontally. By setting a specific anti-opening concave portion, it can better cooperate with the anti-opening convex block 401, making the structure for limiting the locking member 3 more stable.

[0058] Please refer to Figure 3 , in some embodiments, the float cover 4 can include a cover shell 41. An accommodation groove 410 is formed inside the cover shell 41 for the float 2 to be inserted, facilitating driving the float 2 to move downward.

[0059] Specifically, the cover shell 41 is generally in a cylindrical structure, and an accommodation groove 410 is formed inside the cover shell 41. The opening of the accommodation groove 410 faces the float 2. The inner contour shape of the accommodation groove 410 is similar to the outer contour shape of the float 2, and the inner contour size of the accommodation groove 410 is larger than the outer contour size of the float 2, so that the float 2 can be inserted into the accommodation groove 410.

[0060] Combined with Figure 8When the user presses the float cover 4 downward, the bottom surface of the accommodating groove 410 will contact the float 2 and exert a downward force to drive the float 2 to move downward. Since the shape and size of the accommodating groove 410 match the float 2, the float cover 4 can prevent the float 2 from shaking during the process of driving the float 2 to move downward, so that the float 2 can remain stable.

[0061] See also Figure 3 In some embodiments, the float cover 4 can further include a cover plate 42 , which is connected to the peripheral side of the cover shell 41 , and a stopper protrusion 401 is provided on the side of the cover plate 42 facing the locking member 3 .

[0062] Optionally, the cover plate 42 can be integrally formed on the peripheral side of the cover shell 41, and the cover plate 42 can protrude toward the locking piece 3 to form a stop-opening protrusion 401, and the stop-opening protrusion 401 can be arranged opposite to the limiting portion 7. When the float cover 4 moves toward the limiting position, the cover plate 42 gradually approaches the locking piece 3 until the stop-opening protrusion 401 can cooperate with the limiting portion 7. The cover plate 42 is a flat plate structure, and the side of the cover plate 42 facing the locking piece 3 is only provided with the stop-opening protrusion 401, which can facilitate the cooperation between the stop-opening protrusion 401 and the limiting portion 7.

[0063] See also Figure 3 In some embodiments, the float cover 4 may further include a sliding plate 43, which may be connected to the cover shell 41, and the sliding plate 43 may be slidably connected to the pot cover body 1, so that the sliding plate 43 may drive the cover shell 41 and the cover plate 42 to move up and down relative to the pot cover body 1, so that the cover shell 41 and the cover plate 42 may switch between the limit position and the avoidance position.

[0064] Optionally, the sliding plate 43 and the cover plate 42 are respectively connected to the opposite sides of the cover shell 41, and the sliding plate 43 can be slidably connected to the pot cover body 1, so that the cover shell 41 and the cover plate 42 can move up and down relative to the pot cover body 1 through the sliding plate 43. By setting the sliding plate 43, the cover shell 41 and the cover plate 42 can switch more smoothly between the limit position and the avoidance position.

[0065] See also Figure 3 and Figure 6 In some embodiments, the sliding plate 43 is provided with at least one of the guide column 5 and the guide hole 430, and the pot cover body 1 is provided with at least another of the guide column 5 and the guide hole 430, and the guide column 5 and the guide hole 430 are slidably matched.

[0066] Optionally, the sliding plate 43 is provided with two guide holes 430 at intervals, and the pot cover body 1 is provided with two guide columns 5 at intervals, the guide columns 5 are arranged vertically, and the two guide columns 5 are respectively inserted into the two guide holes 430, so that the sliding plate 43 can move up and down along the guide columns 5, so that the sliding plate 43 can drive the cover shell 41 and the cover plate 42 to move up and down relative to the pot cover body 1. By setting the guide columns 5 and the guide holes 430, the sliding plate 43 can move up and down stably.

[0067] Of course, the sliding plate 43 may be provided with two guide posts 5 at intervals, and the pot cover body 1 may be provided with two guide holes 430 at intervals, or the sliding plate 43 may be provided with one guide post 5 and one guide hole 430, and the pot cover body 1 may be provided with another guide hole 430 and another guide post 5, and each guide post 5 may be plugged into and matched with a corresponding guide hole 430.

[0068] See also Figure 2 and Figure 6 In some embodiments, the protection structure may further include a reset member 6, which can be disposed between the float cover 4 and the pot cover body 1, and is used to drive the float cover 4 to move away from the pot cover body 1 to an avoidance position.

[0069] The reset member 6 is usually made of a material with good elasticity and durability, such as a spring or elastic rubber. The reset member 6 is arranged between the float cover 4 and the pot cover body 1. The main function of the reset member 6 is to drive the float cover 4 to move away from the pot cover body 1 to an avoidance position, that is, to drive the float cover 4 to reset.

[0070] Specifically, when the user needs to remove the viscous liquid on the surface of the float 2, the float cover 4 can be pressed downward. At this time, the reset member 6 is compressed, the float cover 4 moves downward and drives the float 2 to fall to the sinking position. After the viscous liquid on the surface of the float 2 is processed, the pressure on the float cover 4 is released. Under the action of the reset member 6, the float cover 4 gradually returns to the initial position, that is, the avoidance position. The reset member 6 can prevent the float cover 4 from interfering with the normal movement of the float 2.

[0071] Optionally, in some embodiments, the reset member 6 is a reset spring 61, which is sleeved on the guide column 5, and the opposite ends of the reset spring 61 are respectively abutted against the float cover 4 and the pot cover body 1. When the user presses the float cover 4 downward, the reset spring 61 is compressed. When the user releases the float cover 4, the reset spring 61 can drive the float cover 4 to reset to the avoidance position.

[0072] See also Figure 2 and Figure 4, in some embodiments, the pot lid assembly 10 may further include a guide member 9. The guide member 9 can be disposed on the pot lid body 1, and the guide member 9 is in sliding fit with the locking member 3 to guide the locking member 3 to slide in the horizontal direction, so as to be able to drive the self-locking portion 8 to engage or disengage with the pot body 20, so that the pot lid body 1 and the pot body 20 are locked or unlocked.

[0073] Optionally, the guide member 9 is fixed to the pot lid body 1. The guide member 9 is formed with a guide cavity. The locking member 3 can be movably disposed in the guide cavity. The guide cavity can limit the degree of freedom of the locking member 3 in the up-and-down direction and the degree of freedom of horizontal swing, so that the locking member 3 can move linearly in the horizontal direction in the guide cavity. It can also be said that the locking member 3 moves in the guide cavity in the horizontal direction toward or away from the pot body 20, and the locking member 3 can drive the self-locking portion 8 to engage or disengage with the pot body 20.

[0074] Therefore, by providing the guide member 9, the locking member 3 can move relative to the pot lid body 1 in the horizontal direction, so that the locking member 3 can drive the self-locking portion 8 to move toward or away from the pot body 20, facilitating the engagement or disengagement of the self-locking portion 8 with the pot body 20.

[0075] Please refer to Figure 2 , in some embodiments, the locking member 3 can include a first limiting end 31, a second limiting end 32, and a connecting arm 33 connecting the first limiting end 31 and the second limiting end 32.

[0076] Specifically, the first limiting end 31 is located above the pot lid body 1, and the first limiting end 31 can be disposed opposite to the float 2. The first limiting end 31 is provided with a limiting portion 7. The limiting portion 7 can be a protrusion, a groove or other structures that can cooperate with the float 2, and is used to trigger a certain action when the float 2 reaches a specific position, so that the float 2 can cooperate with the limiting portion 7. For example, when the float 2 floats upward to the floating position due to high pressure in the pot, the float 2 will cooperate with the limiting portion 7 of the first limiting end 31 to limit the degree of freedom of horizontal movement of the first limiting end 31.

[0077] The second limiting end 32 is connected to the first limiting end 31 through the connecting arm 33. The connecting arm 33 can be movably disposed in the pot lid body 1 in the horizontal direction, so that the connecting arm 33 can drive the first limiting end 31 and the second limiting end 32 to move synchronously in the horizontal direction. And the second limiting end 32 is located on the periphery of the pot lid body 1, so that when the pot lid body 1 is covered on the pot body 20, the second limiting end 32 is located on the side of the pot body 20. The second limiting end 32 is provided with a self-locking portion 8. The self-locking portion 8 can be a lock catch, a card slot or other structures that can cooperate with the pot body 20, and is used to lock the pot lid body 1 and the pot body 20 when the pot lid body 1 is in the closed state.

[0078] When the self-locking portion 8 of the second limiting end 32 is locked with the pot body 20 and there is high pressure inside the pot body 20, at this time, the float 2 will float to the floating position and cooperate with the limiting portion 7 to limit the freedom of horizontal movement of the first limiting end 31. At the same time, the freedom of horizontal movement of the second limiting end 32 is also limited, so that the self-locking portion 8 cannot move relative to the pot cover body 1. Thus, the self-locking portion 8 can lock the pot cover body 1 and the pot body 20, and can prevent the user from opening the pot cover body 1 when there is high pressure in the pot body 20.

[0079] Please refer to Figure 2 , in some embodiments, the limiting portion 7 includes a limiting hole 701, the limiting hole 701 is disposed opposite to the float 2. When the float 2 is in the floating position, the float 2 can cooperate with the limiting hole 701 to limit the freedom of horizontal movement of the locking member 3. When the float cover 4 moves down to the limiting position, it can drive the float 2 to disengage from the limiting hole 701, and the anti-opening convex block 401 can cooperate with the limiting hole 701 to limit the freedom of horizontal movement of the locking member 3.

[0080] Optionally, the limiting hole 701 includes a first sub-hole and a second sub-hole that are communicated with each other. The aperture of the first sub-hole is larger than that of the second sub-hole. The float 2 includes a first cylinder and a second cylinder that are connected to each other. The diameter of the first cylinder is smaller than that of the second cylinder, and the diameter of the second cylinder is adapted to the aperture of the first sub-hole.

[0081] Specifically, in combination with Figure 7 , when the float 2 floats to the floating position, the second cylinder is inserted into the first sub-hole, so that the second cylinder is in interference fit with the first sub-hole, thereby limiting the freedom of horizontal movement of the locking member 3 and locking the locking member 3 with the pot body 20. When the float 2 sinks to the sinking position, the first cylinder is inserted into the first sub-hole or the second sub-hole, and the first cylinder can move back and forth between the first sub-hole and the second sub-hole, so that the locking member 3 can freely move in the horizontal direction within the moving range.

[0082] Therefore, by providing the limiting hole 701, it can be conveniently matched with the float 2, so that when there is high pressure in the pot body 20, the pot cover body 1 and the pot body 20 are locked to prevent the user from being injured by high temperature after accidentally opening the pot cover body 1.

[0083] In combination with Figure 9, when the float cover 4 moves downward to the limit position, the float cover 4 can drive the float 2 to sink to the sinking position, and the anti-opening bump 401 can cooperate with the second sub-hole to limit the degree of freedom of the horizontal movement of the locking member 3, so that the locking member 3 is locked with the pot body 20. Thus, the float cover 4 can easily drive the float 2 to move downward, so that the float 2 can also move downward relative to the lid body 1 when it is stuck, and when the float 2 is in the sinking position, the float cover 4 can cooperate with the locking member 3 to lock the lid body 1 and the pot body 20, preventing the user from forcibly opening the lid body 1 when there is pressure in the pot, playing a protective role.
