The pressure cooker is mainly composed of a pressure cooker cover and a cooker body, and the pressure cooker cover and the cooker body are connected by a clamp, and the clamp can move relative to the cooker body to achieve the purpose of clamping the pressure cooker cover and the cooker body at the same time or canceling the clamp. However, the existing clamp device has a complex structure, is not easy to disassemble and assemble, and has a high cost. Utility Model Content

[0003] The present application provides a pressure cooker cover and a pressure cooker to solve the technical problems in the above-mentioned prior art that the clamp assembly has a complex structure, is difficult to disassemble and assemble, and has a high cost.

[0004] In a first aspect, the present application provides a pressure cooker cover, which comprises a detachably connected cover body and a clamp device, wherein the clamp device comprises:

[0005] A support member, used for connecting the cover body;

[0006] At least two clamps, slidably connected to the support member and capable of sliding along the radial direction of the cover body;

[0007] A driving member is rotatably connected to the supporting member, and the driving member is provided with a driving portion corresponding to each of the clamps, the driving portion deviates from the rotation center of the driving member, and the driving portion abuts against one end of the clamp close to the axis of the cover body to force the clamp to move away from the cover body to cancel the clamping.

[0008] The pressure cooker lid provided by the present application comprises a detachably connected lid body and a clamp device, wherein the clamp device comprises a support, at least two clamps and a driving member; the support is used to connect the lid body, and the other components of the clamp device are installed on the support, so that the clamp device can be used as a whole and can be detachably connected with the lid body, thereby facilitating disassembly, assembly, cleaning and maintenance; the clamp is slidably connected to the support, and can slide along the radial direction of the lid body, thereby achieving clamping and canceling the clamping; the driving member is rotatably connected to the support, and the driving member is provided with a driving part corresponding to each clamp, the driving part deviates from the rotation center of the driving member, and the driving part abuts against one end of the clamp close to the axis of the lid body to force the clamp to move in a direction away from the lid body to cancel the clamping. On the one hand, the driving part and the clamp are in contact and abut with each other, and there is no need to set a special driving matching structure on the clamp, which simplifies the mutual cooperation between the driving part and the clamp, thereby simplifying the overall structure of the clamp device and reducing the production cost of the clamp device; on the other hand, the driving member directly interacts with the clamp, and there is no need to transmit through other intermediate components, thereby improving the force transmission efficiency and the stability of the clamp action.

[0009] Optionally, the clamp device further comprises an elastic member, which is connected to one end of the clamp close to the axis of the cover body to force the clamp to move in a direction close to the axis of the cover body to achieve clamping. Under the action of the elastic member, it is possible to ensure that the clamp and the driving part maintain a state of contact with each other, preventing the driving part from idling or collision between the driving part and the clamp.

[0010] Optionally, there are two clamps, which are arranged opposite to each other and connected to each other through the elastic member, so as to force the two clamps to move closer to each other to achieve clamping. On the one hand, the two clamps are driven to move by one elastic member at the same time, which reduces the number of parts and makes the overall structure more concise; on the other hand, the expansion and contraction direction of the elastic member is parallel to the movement direction of the clamps, which can improve the effective utilization of force and make the movement of the clamps more sensitive and efficient.

[0011] Optionally, when the two clamps are clamped, the two opposite sides of the driving part respectively press against the two clamps. On the one hand, the distance between the two clamps can be reduced as much as possible, so that the overall structure is more compact; on the other hand, the two sides of the driving part are stressed at the same time, so that the driving part and the clamps can stay stably in the current position, thereby preventing the position of the clamps from changing during use and affecting the safety of use.

[0012] Optionally, each of the clamps is connected to two elastic members, which are arranged along the width direction of the clamps and are symmetrically arranged. Both sides of the clamps are subjected to force synchronously to prevent the clamps from shaking or tilting along their own width direction, causing accidents such as jamming during the movement of the clamps, and affecting the normal use of the clamp device.

[0013] Optionally, the clamp includes: a first extension portion, the first extension portion extends along the radial direction of the cover body; a second extension portion, the second extension portion is located at one end of the first extension portion close to the axis of the cover body, and the driving portion abuts against the second extension portion; the second extension portion extends along the width direction of the first extension portion, and both ends of the second extension portion extend beyond the edge of the first extension portion. The width of the second extension portion is greater than that of the first extension portion, so as to increase the eccentric distance of the driving portion, thereby increasing the convenience of operation and the sensitivity of the clamp action.

[0014] Optionally, one of the driving member and the supporting member is provided with a locking member, and the other is provided with a locking groove, and the locking member is inserted into or slides out of the locking groove as the driving member rotates. When the locking member is inserted into the locking groove, the driving member and the supporting member are locked with each other, the driving part is fixed, and the driving part and the clamp are pressed against each other, thereby limiting the position of the clamp to prevent the state of the clamp from changing during use and affecting the normal operation of the user; when the locking member slides out of the locking groove, the driving member and the supporting member can rotate relative to each other, the driving part can rotate freely, and the clamp can slide freely, so that the state of the clamp can be switched as needed.

[0015] Optionally, within the rotational stroke of the driving member, the driving portion has a clamping position, a releasing position and a disassembly position arranged in sequence;

[0016] When the driving part rotates to the clamping position, the clamp is clamped, thereby realizing a reliable connection between the pressure cooker cover and the cooker body, thereby ensuring the safety of the pressure cooker;

[0017] When the driving part rotates to the release position, the clamp cancels the clamping, so that the pressure cooker cover can be separated from the cooker body to open the cover;

[0018] When the driving part rotates to the disassembly position, the clamp is separated from the edge of the cover body, avoiding interference or collision between the clamp and the edge of the cover body during the disassembly of the clamp device, so that the clamp device can be disassembled smoothly, thereby meeting the disassembly and cleaning requirements of the clamp device.

[0019] Optionally, the cover body is provided with a detachable check valve, the check valve is passed through the cover body and can be raised and lowered along the cover body; the clamp is provided with an avoidance groove, the check valve is passed through the avoidance groove and can slide along the avoidance groove; when the driving member rotates to the release position, the check valve and the groove wall of the avoidance groove abut against each other. Under normal use, the check valve limits the farthest position of the clamp. After the clamp slides to the position where the clamp is unclamped, it cannot slide further in the direction away from the axis of the cover body, thereby ensuring that the clamp device will not accidentally fall off when in use; when the clamp device needs to be disassembled, the check valve needs to be removed first. After the clamp slides to the position where the clamp is unclamped, it can slide further in the direction away from the axis of the cover body, thereby achieving smooth disassembly of the clamp device.

[0020] A second aspect of the present application provides a pressure cooker, comprising a cooker body and any one of the pressure cooker covers provided in the present application, wherein when the pressure cooker cover is connected to the cooker body, the clamping device can clamp the pressure cooker cover and the cooker body simultaneously.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0056] like Figure 1-Figure 8 As shown, the embodiment of the present application provides a pressure cooker, which includes a pressure cooker cover 01 and a pot body 02, and the pressure cooker cover 01 is detachably connected to the pot body 02. The pressure cooker cover 01 includes a detachably connected cover body 1 and a clamp device 2, for example, the clamp device 2 can be connected to the cover body 1 by means of screws or buckles, and when the pressure cooker cover 01 is connected to the pot body 02, the clamp device 2 can clamp the pressure cooker cover 01 and the pot body 02 at the same time, so as to achieve a reliable connection between the pressure cooker cover 01 and the pot body 02; the cover body 1 is provided with a sealing ring, a pressure limiting valve and a non-opening valve 11; the sealing ring can form a sealing state between the pressure cooker cover 01 and the pot body 02 to prevent the gas in the pot from leaking between the pressure cooker cover 01 and the pot body 02; the pressure limiting valve is used to limit the maximum pressure in the pot; the non-opening valve 11 is penetrated by the pressure cooker cover 01, and can rise or fall along the pressure cooker cover 01.

[0057] like Figure 2-Figure 5As shown, further, the clamp device 2 includes a support member 21, at least two clamps 22 and a driving member 23. The support member 21 is used to connect the cover body 1, that is, the support member 21 forms the main part of the clamp device 2, and the other parts of the clamp device 2 are installed on the support member 21, so that the clamp device 2 can be used as a whole and can be detachably connected with the cover body 1, thereby facilitating disassembly, assembly, cleaning and maintenance; the clamp 22 is slidably connected to the support member 21, and can slide along the radial direction of the cover body 1, so as to achieve clamping and canceling; the driving member 23 is rotatably connected to the support member 21, and the driving member 23 is provided with a driving part 231 corresponding to each clamp 22, that is, the driving part 231 is arranged one by one with the clamp 22, the driving part 231 deviates from the rotation center of the driving member 23, and the driving part 231 abuts against one end of the clamp 22 close to the axis of the cover body 1, so as to force the clamp 22 to move away from the cover body 1 to cancel the clamping. On the one hand, the driving part 231 and the clamp 22 are in contact and abutment with each other, and there is no need to set a special driving matching structure in the clamp 22, which simplifies the mutual cooperation between the driving member 23 and the clamp 22, thereby simplifying the overall structure of the clamp device 2 and reducing the production cost of the clamp device 2; on the other hand, the driving member 23 directly interacts with the clamp 22 without the need for transmission through other intermediate components, thereby improving the force transmission efficiency and the stability of the clamp 22 action.

[0058] Specifically, the support member 21 is centered on the axis of the cover body 1, and the edge of the support member 21 is provided with a cavity extending radially along the cover body 1, and a part of the clamp 22 is accommodated in the cavity and can slide along the cavity; when the clamp 22 moves along the cavity toward the axis of the cover body 1, the clamp 22 is clamped, and the check valve 11 can rise freely, ensuring the safety of closing the cover; when the clamp 22 moves along the cavity toward the axis away from the cover body 1, the clamp 22 cancels the clamping, and the check valve 11 is blocked from rising by the clamp 22, ensuring the safety of opening the cover. To facilitate the installation of the clamp 22, the support member 21 can be configured as a first part 21a and a second part 21b that are assembled with each other, and the above-mentioned cavity is formed between the first part 21a and the second part 21b, and the first part 21a and the second part 21b can be fixed by screws or the like.

[0059] Furthermore, the driving member 23 is stacked and arranged above the support member 21, and the rotating shaft of the driving member 23 is parallel to the axis of the cover body 1. The driving member 23 can be connected to the support member 21 by means of screws or the like, so as to realize the connection between the driving member 23 and the cover head. The driving part 231 is convexly arranged at the bottom of the driving member 23, and the driving part 231 passes through the support member 21 and abuts against the clamp 22, so as to push the clamp 22 to move in the direction away from the axis of the cover body 1. The support member 21 can be provided with an arc guide groove 212, and the driving part 231 is passed through the arc guide groove 212 and can slide along the arc guide groove 212, so as to guide the driving part 231 and increase the stability of the action of the driving member 23.

[0060] Furthermore, one of the driving member 23 and the supporting member 21 is provided with a locking member 232 (for example, an elastic pin or a protrusion, etc.), and the other is provided with a locking groove 211. The number of the locking grooves 211 can be reasonably set as needed. For example, the locking grooves 211 can be respectively set corresponding to the above-mentioned clamping position 231a, the release position 231b and the disassembly position 231c, and the locking member 232 is inserted into or slides out of the locking groove 211 as the driving member 23 rotates. When the locking member 232 is inserted into the locking groove 211, the driving member 23 and the supporting member 21 are locked with each other, the driving portion 231 is fixed, and the driving portion 231 and the clamp 22 are pressed against each other, thereby limiting the position of the clamp 22 and preventing the state of the clamp 22 from changing during use and affecting the normal operation of the user; when the locking member 232 slides out of the locking groove 211, the driving member 23 and the supporting member 21 can rotate relative to each other, the driving portion 231 can rotate freely, and the clamp 22 can slide freely, so that the state of the clamp 22 can be switched as needed.

[0061] like Figure 2 , Figure 6-Figure 8 As shown, further, the clamp device 2 also includes an elastic member 24, such as a pre-tensioned spring, etc. The elastic member 24 is connected to one end of the clamp 22 close to the axis of the cover body 1 to force the clamp 22 to move in the direction close to the axis of the cover body 1 to achieve clamping. Under the action of the elastic member 24, it can ensure that the clamp 22 and the driving part 231 maintain a state of contact with each other to prevent the driving part 231 from idling or collision between the driving part 231 and the clamp 22. It can be understood that the clamp 22 can also be moved in the direction close to the cover body 1 by other appropriate driving methods, for example, the user directly pushes the clamp 22 to move in the direction close to the axis of the cover body 1 to achieve clamping, etc.

[0062] Furthermore, each clamp 22 is connected to two elastic members 24, which are arranged along the width direction of the clamp 22 and are symmetrically arranged with respect to each other, so that both sides of the clamp 22 are subjected to force synchronously, thereby preventing the clamp 22 from shaking or tilting along its own width direction, causing accidents such as jamming during the movement of the clamp 22, and affecting the normal use of the clamp device 2.

[0063] In one embodiment, there are two clamps 22, which are arranged opposite to each other and connected to each other by an elastic member 24, so as to force the two clamps 22 to move close to each other to achieve clamping. On the one hand, the two clamps 22 are driven to move by one elastic member 24 at the same time, which reduces the number of parts and makes the overall structure more concise; on the other hand, the expansion and contraction direction of the elastic member 24 is parallel to the movement direction of the clamps 22, which can improve the effective utilization of force and make the movement of the clamps 22 more sensitive and efficient. It can be understood that when the number of clamps 22 is more than two, at least two clamps 22 can also be connected to each other by an elastic member 24, so that the two clamps 22 are driven to move by the same elastic member 24 at the same time.

[0064] Furthermore, the clamp 22 includes a first extension portion 221 and a second extension portion 222. The first extension portion 221 extends along the radial direction of the cover body 1 to guide and limit the clamp 22; the second extension portion 222 is located at one end of the first extension portion 221 close to the axis of the cover body 1, and the driving portion 231 abuts against the second extension portion 222 to push the clamp 22 to move in a direction away from the axis of the cover body 1.

[0065] Furthermore, the second extension portion 222 extends along the width direction of the first extension portion 221, and both ends of the second extension portion 222 extend beyond the edge of the first extension portion 221, that is, the width of the second extension portion 222 is greater than the width of the first extension portion 221, so as to increase the eccentric distance of the driving portion 231, thereby increasing the convenience of operation and the sensitivity of the action of the clamp 22. Specifically, due to the increase in the eccentric distance of the driving portion 231, the rotation radius of the driving portion 231 increases, and the deflection angle required when the driving portion 231 pushes the clamp 22 is reduced. The user only needs to rotate the driving member 23 by a smaller angle, and the clamp 22 can move a larger distance in the radial direction.

[0066] Further, when each clamp 22 is connected to two elastic members 24, the two ends of the second extension 222 are respectively connected to an elastic member 24, and the end of the elastic member 24 away from the second extension 222 can be connected to the support member 21, or connected to the second driving portion 231 of the other clamp 22 opposite to the elastic member 24, and the elastic member 24 forces the clamp 22 to move in a direction close to the axis of the cover 1 to achieve clamping. By arranging the elastic member 24 at the two ends of the second extension 222, the span between the two elastic members 24 is increased, so that the movement of the clamp 22 is more stable.

[0067] Furthermore, when the two clamps 22 are clamped, the two opposite sides of the driving part 231 are respectively pressed against the two clamps 22 (refer to Figure 6 ), that is, the same driving part 231 contacts and presses against the two clamps 22 at the same time, and the driving part 231 is clamped by the two clamps 22. On the one hand, the distance between the two clamps 22 can be reduced as much as possible, so that the overall structure is more compact; on the other hand, both sides of the driving part 231 are stressed at the same time, so that the driving part 231 and the clamps 22 can stay stably at the current position, thereby preventing the position of the clamps 22 from changing during use, which affects the safety of use.

[0068] Furthermore, within the rotation stroke of the driving member 23, the driving part 231 has at least a clamping position 231a and a loosening position 231b to meet the requirements of opening and closing the lid of the pressure cooker. When the driving part 231 rotates to the clamping position 231a, the clamp 22 is clamped, thereby realizing a reliable connection between the pressure cooker lid 01 and the pot body 02, ensuring the safety of the pressure cooker; when the driving part 231 rotates to the loosening position 231b, the clamping is canceled, so that the pressure cooker lid 01 can be separated from the pot body 02 to realize opening.

[0069] Furthermore, within the rotational stroke of the driving member 23, the driving part 231 has a disassembly position 231c, and the disassembly position 231c is located on the side of the release position 231b away from the clamping position 231a, that is, the clamping position 231a, the release position 231b and the disassembly position 231c are arranged in sequence, and when the driving part 231 rotates to the release position 231b, further rotating the driving member 23 can move the driving part 231 to the disassembly position 231c. When the driving part 231 rotates to the disassembly position 231c, the clamp 22 is completely separated from the edge of the cover body 1, avoiding interference or collision between the clamp 22 and the edge of the cover body 1 during the disassembly process of the clamp device 2, so that the clamp device 2 can be smoothly disassembled, thereby meeting the disassembly and cleaning requirements of the clamp device 2.

[0070] Furthermore, the cover body 1 is provided with a detachable check valve 11, which is disposed through the cover body 1 and can be raised and lowered along the cover body 1; the clamp 22 is provided with an escape groove 223, and the check valve 11 is disposed through the escape groove 223 and can slide along the escape groove 223; when the driving member 23 rotates to the release position 231b, the check valve 11 and the groove wall of the escape groove 223 abut against each other. Under normal use, the check valve 11 limits the farthest position of the clamp 22, and after the clamp 22 slides to the position of canceling the clamping, it cannot slide further in the direction away from the axis of the cover body 1, thereby ensuring that the clamp device 2 will not accidentally fall off in the use state; when the clamp device 2 needs to be disassembled, the check valve 11 needs to be removed first, and after the clamp 22 slides to the position of canceling the clamping, it can slide further in the direction away from the axis of the cover body 1, thereby realizing the smooth disassembly of the clamp device 2.

[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
