Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, and particularly relates to a pot cover and a clamp-type pressure cooker. Background Art

[0002] A clamp-type pressure cooker is a kitchen utensil that uses high-pressure steam to speed up the cooking process. After the pot body and the pot cover are combined, a sealed space is formed. Its characteristic is that by increasing the pressure inside the pot, the boiling point of water is raised, thereby realizing high-temperature cooking and greatly improving the cooking efficiency. The clamp-type pressure cooker mainly includes two parts: a pot body and a pot cover, and the pot cover realizes unlocking and locking with the pot body through the opening and closing of the clamp.

[0003] In the related art, the structure for controlling the opening and closing of the clamp has a high failure rate, which affects the normal use of the pressure cooker. Summary of the Utility Model

[0012] Optionally, the body is provided with an actuating member for driving the first clamp to move; the actuating member includes a slider slidable relative to the body. The first clamp is provided with a mounting hole for mounting the slider. The slider has an abutting end and a connecting end arranged oppositely. The connecting end is connected to the side wall of the mounting hole close to the second clamp through an elastic member, and the elastic member keeps the abutting end in abutment with the side wall of the mounting hole far from the second clamp.

Based on the embodiments in the implementation manners, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0027] As used in this specification, the phrase "in one embodiment" or "instance" or "example" means that the specific features, structures, or characteristics described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" at various positions in the specification does not necessarily refer to the same embodiment.

[0028] Embodiment:

[0029] As Figure 1 and Figure 2 shown, this embodiment provides a pot lid, including a main body 1 and a clamp assembly 2 that opens and closes along the radial direction of the main body 1. The clamp assembly 2 includes a first clamp 21 and a second clamp 22. The main body 1 is provided with a transmission part 4 that can rotate relative to the main body 1. The first clamp 21 and the second clamp 22 are respectively connected to the transmission part 4. The movement of one of the first clamp 21 and the second clamp 22 can drive the other to move synchronously in the opposite direction through the rotation of the transmission part 4.

[0030] In this embodiment, the pot lid includes a body 1 and a clamp assembly 2 that opens and closes radially along the body 1. The unlocking or locking of the pot lid and the pot body is achieved by the opening and closing of the clamp assembly 2. The clamp assembly 2 includes a pair of first clamps 21 and second clamps 22 arranged in pairs. When it is necessary to unlock the pot lid and the pot body, the first clamps 21 and the second clamps 22 move away from each other and separate from the pot body. When it is necessary to lock the pot lid and the pot body, the first clamps 21 and the second clamps 22 move closer to each other and clamp the pot body. In this embodiment, the clamp assembly 2 only includes a pair of first clamps 21 and second clamps 22. In other embodiments, the clamp assembly 2 may also include multiple pairs of first clamps 21 and second clamps 22 that move in opposite directions, which is not limited here. Specifically, the body 1 is provided with a transmission member 4 for linking the first clamps 21 and the second clamps 22. When the first clamps 21 move, one end of the transmission member 4 rotates relative to the first clamps 21, and the second clamps 22 at the other end of the transmission member 4 move synchronously in a direction opposite to the moving direction of the first clamps 21. In the related art, the first clamps 21 and the second clamps 22 are generally driven by a gear assembly, but the gear structure is fragile and prone to breakage. In this embodiment, through the rotation of the transmission member 4, the first clamps 21 and the second clamps 22 achieve reverse synchronous movement, improving the smoothness of the clamp opening and closing action. Compared with the gear transmission method, the structure of the transmission member 4 has good stability, preventing the clamp assembly 2 from accidentally opening and improving the safety of the pot body. Compared with the gear transmission method, the reverse synchronous movement achieved by the transmission member 4 has better smoothness. Gear transmission may generate impacts and vibrations during the meshing process, while the transmission member 4 does not require meshing transmission, and its structure is more concise, effectively reducing these adverse factors. Therefore, the transmission member 4 in this application makes the opening and closing actions of the clamps more smooth and fluent, improving the user experience. Moreover, the transmission member 4 reduces the risk of failures caused by gear wear, improving the overall safety of the pot body. In addition, by using the transmission member 4 to replace the traditional gear transmission method, not only the number and complexity of the transmission components are reduced, but also the overall structure is simplified, the manufacturing cost and maintenance difficulty are reduced, and the reliability and economy of the equipment are improved.

[0031] In other embodiments, it may also be that the second clamps 22 drive the transmission member 4 to rotate, and the transmission member 4 then drives the first clamps 21 to move in the opposite direction.

[0032] As Figure 2 and Figure 3 shown, both ends of the transmission member 4 are respectively provided with a first transmission shaft 41 and a second transmission shaft 42 that protrude from the surface of the transmission member 4; the first clamps 21 include a first transmission part 211 provided with a first shaft hole 2111, and the second clamps 22 include a second transmission part 221 provided with a second shaft hole 2211. The first transmission shaft 41 passes through the first shaft hole 2111, and the second transmission shaft 42 passes through the second shaft hole 2211, so that the transmission member 4 links the first clamps 21 and the second clamps 22.

[0033] In this embodiment, the transmission member 4 is configured in a plate shape. Both the first transmission shaft 41 and the second transmission shaft 42 protrude from the surface of the transmission member 4. The first transmission portion 211 of the first clamp 21 is linked with the transmission member 4 through the first shaft hole 2111, and the second transmission portion 221 of the second clamp 22 is linked with the transmission member 4 through the second shaft hole 2211. The shape of the first shaft hole 2111 matches the shape of the first transmission shaft 41, and the shape of the second shaft hole 2211 matches the shape of the second transmission shaft 42. Additionally, the transmission member 4 is not parallel or coincident with the first clamp 21 and the second clamp 22, so that when the first clamp 21 moves, it drives the transmission member 4 to rotate, and the transmission member 4 then drives the second clamp 22 to move in the opposite direction relative to the first clamp 21. In other embodiments, the transmission member 4 can also be configured in a shaft shape or the like.

[0034] As Figure 3 and Figure 4 shown, the first transmission portion 211 and the second transmission portion 221 are overlapped. The first transmission portion 211 is provided with a first guiding groove 2112 corresponding to the position of the second shaft hole 2211, and the second transmission portion 221 is provided with a second guiding groove 2212 corresponding to the position of the first shaft hole 2111. The first transmission shaft 41 passes through the first shaft hole 2111 and the second guiding groove 2212 and moves along the second guiding groove 2212. The second transmission shaft 42 passes through the second shaft hole 2211 and the first guiding groove 2112 and moves along the first guiding groove 2112. The first guiding groove 2112 and the second guiding groove 2212 are parallel to each other and are both configured as oblong.

[0035] In this embodiment, the first transmission portion 211 and the second transmission portion 221 are overlapped, making the overall structure more compact and facilitating connection and transmission through the transmission member 4. The first transmission shaft 41 passes through the first shaft hole 2111 of the first clamp 21 and the second guiding groove 2212 of the second clamp 22 at the same time, and the first transmission shaft 41 can move within the second guiding groove 2212. Then, while transmitting the power from the first clamp 21, the first transmission shaft 41 can also guide the first clamp 21 to move in a specific direction (i.e., the direction of the second guiding groove 2212). Similarly, the second transmission shaft 42 passes through the second shaft hole 2211 and the first guiding groove 2112 at the same time, and the second transmission shaft 42 can move within the first guiding groove 2112. Then, while transmitting the power, the second transmission shaft 42 can also guide the second clamp 22 to move in a specific direction (i.e., the direction of the first guiding groove 2112). Additionally, since the first guiding groove 2112 and the second guiding groove 2212 are parallel to each other and are both configured as oblong, the moving trajectories of the first clamp 21 and the second clamp 22 are both straight. In other embodiments, the first guiding groove 2112 and the second guiding groove 2212 can also be set as arc-shaped grooves or the like.

[0036] As Figure 5 and Figure 6As shown in the figure, the transmission member 4 includes a bottom plate 43. The first transmission shaft 41 and the second transmission shaft 42 are respectively arranged at both ends of the bottom plate 43. A central hole 431 penetrating the bottom plate 43 is formed between the first transmission shaft 41 and the second transmission shaft 42. A central shaft 432 fixedly connected to the body 1 is inserted into the central hole 431.

[0037] In this embodiment, since the central shaft 432 fixedly connected to the body 1 is inserted into the central hole 431, the bottom plate 43 can rotate around the central shaft 432 to realize the rotation of the first transmission shaft 41 and the second transmission shaft.

[0038] As Figure 3 and Figure 4 shown in the figure, a pressure relief valve 11 is inserted through the body 1 along its thickness direction. The first clamp 21 is provided with a first through hole 212, and the second clamp 22 is provided with a second through hole 222 corresponding to the position of the first through hole 212. The pressure relief valve 11 passes through the first through hole 212 and the second through hole 222.

[0039] In this embodiment, a pressure relief valve 11 is inserted through the body 1 along its thickness direction. When the pressure in the pot body rises to a certain level, the pressure relief valve 11 also rises. Specifically, a part of the first clamp 21 overlaps with the second clamp 22. In this overlapping part, the first clamp 21 is provided with a first through hole 212, and the second clamp 22 is provided with a second through hole 222 which is vertically opposite to the first through hole 212, that is, the pressure relief valve 11 passes through the overlapping part of the first clamp 21 and the second clamp 22 while passing through the body 1 to prevent the first clamp 21 and the second clamp 22 from moving away from each other and releasing the locking of the pot body when the pressure in the pot body is relatively high. And the pressure relief valve 11 passes through both the first clamp 21 and the second clamp 22, which can further prevent the first clamp 21 and the second clamp 22 from shaking or misaligning, improve safety and prevent accidental opening. In addition, in this embodiment, the pressure relief valve 11 is eccentrically arranged on the body 1, that is, closer to the end of the second clamp 22. Therefore, in order for the pressure relief valve 11 to pass through both the first clamp 21 and the second clamp 22 at the same time, the length of the first clamp 21 is greater than that of the second clamp 22. In other embodiments, when the pressure relief valve 11 is arranged at the middle position of the body 1, the lengths of the first clamp 21 and the second clamp 22 may also be the same.

[0040] As Figure 4 shown in the figure, the pressure relief valve 11 includes a pressure relief rod 111. The first through hole 212 is formed with a first relief portion 2121 adapted to the pressure relief rod 111, and the second through hole 222 is formed with a second relief portion 2221 adapted to the pressure relief rod 111.

[0041] In this embodiment, the anti-opening rod 111 also extends into the first through hole 212 and the second through hole 222 when the pressure in the pot body is not high. Therefore, a first relief portion 2121 adapted to the shape of the anti-opening rod 111 is formed in the first through hole 212, and a second relief portion 2221 adapted to the shape of the anti-opening rod 111 is formed in the second through hole 222 to prevent the anti-opening rod 111 from affecting the opening and closing of the clamp assembly 2.

[0042] The body 1 is provided with an actuator 3 for driving the movement of the first clamp 21; the actuator 3 includes a slider 31 slidable relative to the body 1. The first clamp 21 is provided with a mounting hole 213 for mounting the slider 31. The slider 31 has an abutting end 311 and a connecting end 312 arranged oppositely. The connecting end 312 is connected to the side wall of the mounting hole 213 close to the second clamp 22 through an elastic member 32, and the elastic member 32 keeps the abutting end 311 in abutment with the side wall of the mounting hole 213 away from the second clamp 22.

[0043] In this embodiment, the slider 31 is installed in the mounting hole 213 of the first clamp 21. The slider 31 has two oppositely arranged ends, namely the abutting end 311 and the connecting end 312. The connecting end 312 is connected to the side wall of the mounting hole 213 close to the second clamp 22 through an elastic member 32. The elastic member 32 has a tendency to extend towards the slider 31 so that the abutting end 311 of the slider 31 abuts against the side wall of the mounting hole 213 away from the second clamp 22, facilitating the user to apply force to the slider 31 and slide to push the first clamp 21 away from the second clamp 22.

[0044] The actuator 3 includes a push block 33 rotatably connected to the slider 31. The slider 31 is provided with a receiving groove 313, and one end of the push block 33 facing the slider 31 is rotatably arranged in the receiving groove 313.

[0045] In this embodiment, the push block 33 is received in the receiving groove 313 of the slider 31. When the push block 33 rotates relative to the slider 31, it can drive the slider 31 to translate. When it is necessary to control the opening and closing of the clamp, an external force can be applied to the push block 33 to drive the movement of the slider 31. Since the push block 33 and the slider 31 are rotatably connected, the movement (rotation) of the push block 33 will be converted into a linear movement (sliding) of the slider 31 in a certain direction.

[0046] As Figure 2 and Figure 5 shown, the actuator 3 includes a handle 34. The handle 34 has a free end 341 and a hinged end 342 connected to the push block 33; the body 1 is provided with a seat box 12. A cavity 121 is formed in the seat box 12, and the hinged end 342 extends into the cavity 121 and is hinged to the seat box 12.

[0047] In this embodiment, the handle 34 is the part directly operated by the user, which has a free end 341 and a hinged end 342 connected to the push block 33. The free end 341 facilitates the user's grip, while the hinged end 342 is connected to the push block 33 to achieve the transmission and conversion of force. Specifically, there is an angle between the hinged end 342 and the free end 341. When the user lifts the handle 34, the hinged end 342 rotates and drives the push block 33 to rotate, ultimately causing the slider 31 to translate. A seat box 12 is provided on the body 1, and an accommodation cavity 121 is formed inside the seat box 12. This accommodation cavity 121 provides support and positioning for the handle 34.

[0048] As Figure 3 shown, the first clamp 21 includes a first clamping portion 214, and the second clamp 22 includes a second clamping portion 223. The first clamping portion 214 is provided at one end of the first clamp 21 away from the second clamp 22, and the second clamping portion 223 is provided at one end of the second clamp 22 away from the first clamp 21.

[0049] In this embodiment, the first clamping portion 214 and the second clamping portion 223 are used to perform the clamping action on the pot body. The first clamping portion 214 is detachably connected to the first transmission portion 211, and the second clamping portion 223 is detachably connected to the second transmission portion 221. In other embodiments, the first clamping portion 214 can also be welded or integrally provided with the first transmission portion 211, and the second clamping portion 223 can also be welded or integrally provided with the second transmission portion 221.

[0050] It should be noted that after the handle 34 is lifted, the first clamp 21 and the second clamp 22 open and release the locking of the pot body. When it is necessary to close the first clamp 21 and the second clamp 22, manually bringing the first clamp 21 and the second clamp 22 closer to each other can lock the first clamp 21 and the second clamp 22 with the pot body.

[0051] This embodiment also provides a clamp-type pressure cooker, which includes a pot lid and a pot body. The pot lid includes the aforementioned pot lid.

[0052] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
