Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, and particularly relates to a pressure cooker cover and a pressure cooker. BACKGROUND

[0002] A pressure cooker is a common cooking utensil, which mainly functions to increase the temperature of heating and the speed of heating by increasing the air pressure in the cooker. The pressure cooker mainly comprises a pressure cooker cover and a cooker body, and the pressure cooker cover and the cooker body are connected through a clamp assembly. The clamp assembly can move relative to the cooker body to clamp or unclamp the pressure cooker cover and the cooker body at the same time. However, the existing clamp assembly needs to be matched with the structure and shape of the pressure cooker cover, which leads to high manufacturing cost of the pressure cooker. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a pressure cooker cover and a pressure cooker to improve the versatility of the clamp assembly and reduce the manufacturing cost of the pressure cooker.

[0004] The first aspect of the present application provides a pressure cooker cover, which comprises a cover body and a clamp assembly, and the clamp assembly comprises:

[0005] At least two clamps, which are arranged at the edge of the cover body and can slide along the radial direction of the cover body;

[0006] At least two lock catchers, which are arranged at the side of the clamps close to the axis of the cover body and can slide along the radial direction of the cover body;

[0007] A flexible traction member, which connects the clamps and the lock catchers;

[0008] When the lock catchers are close to each other, the lock catchers can realize locking, the lock catchers tighten the flexible traction member, and the flexible traction member drives the clamps to realize clamping;

[0009] When the lock catchers are unlocked, the lock catchers can be away from each other, the lock catchers loosen the flexible traction member, and the clamps can be unclamped.

[0010] The pressure cooker cover provided by the application comprises a cover body and a clamp assembly, the clamp assembly comprises at least two clamps, at least two locking pieces and a flexible traction piece; the clamps are arranged at the edge of the cover body and can slide along the radial direction of the cover body to realize clamping or unclamping; the locking pieces are arranged at the side of the clamps close to the axis of the cover body and can slide along the radial direction of the cover body to realize locking or un-locking; the flexible traction piece connects the clamps and the locking pieces; when the locking pieces are close to each other, the locking pieces can realize locking, the locking pieces tighten the flexible traction piece, and the flexible traction piece drives the clamps to realize clamping; when the locking pieces are un-locked, the locking pieces can be away from each other, the locking pieces loosen the flexible traction piece, and the clamps can be un-clamped under the action of external force. On the one hand, the distance between the locking pieces and the clamps can be set according to the size of the cover body, and only the length of the flexible traction piece needs to be changed, so that the clamp assembly can be applied to cover bodies of various sizes; on the other hand, since the flexible traction piece can deform freely, the clamp assembly can adapt to cover bodies of various structural shapes. In addition, the application uses the locking pieces to keep the clamps in the clamped state, which can effectively improve the stability of the clamps in the clamped state and prevent the clamps from loosening accidentally due to external forces such as vibration or impact.

[0011] Optionally, the number of the locking pieces is two, the two locking pieces are arranged opposite to each other along the radial direction of the cover body, and the two locking pieces are buckled to each other to realize locking. The cover body and other components only provide installation and guiding actions for the locking pieces, and only need to adapt the shape of the locking pieces to the cover head and other components; the locking is formed between the two locking pieces, and does not depend on the cover head and other components, which can improve the reliability of the locking of the locking pieces. In addition, the user can simultaneously apply external force to the two locking pieces by pinching, so that the two locking pieces are close to each other to realize locking, thereby improving the convenience of operation.

[0012] Optionally, one of the locking pieces is a first locking piece, and the other is a second locking piece; the first locking piece is provided with a movable part, and the second locking piece is provided with a matching part; the movable part moves along the direction close to or away from the axis of the locking piece; when the first locking piece and the second locking piece are close to each other, the movable part and the matching part are stacked along the direction close to or away from the axis of the locking piece, and the movable part and the matching part are buckled to each other to realize locking. The matching part is located at one side of the movable part along the movement direction of the movable part, so that the movable part can move towards the matching part to realize buckling, and the movable part can move away from the matching part to cancel the buckling. The movement stroke of the movable part limits the buckling depth of the movable part and the matching part, which can prolong the service life of the locking piece while ensuring the reliability of the buckling.

[0013] Optionally, one end of the movable part is pivotally connected to the first locking member, and the other end extends towards the second locking member. The movable part rotates towards or away from the axis of the locking member to reduce the resistance of the movable part and increase the smoothness of the movable part.

[0014] Optionally, the movable part is provided with a clamping protrusion, and the matching part is provided with a clamping groove arranged through the through groove of the matching part. The pressure cooker cover further comprises an unlocking member, which is respectively located on the two opposite sides of the matching part. The unlocking member and the clamping protrusion are in abutment through the clamping groove. On the one hand, the unlocking member directly abuts and pushes the clamping protrusion, so that the clamping protrusion is out of the clamping groove, which can make the operation of the unlocking member more labor-saving and efficient. On the other hand, the unlocking member and the movable part are in abutment within the range of the matching part, which can make the external form of the locking member more regular and the overall structure of the pressure cooker cover more compact.

[0015] Optionally, the cover is provided with a stop valve which rises and falls along the axial direction of the cover. One side of at least one of the locking members extends a stop portion, at least a part of the stop portion is located above the stop valve, and the stop portion is provided with an avoiding opening. When the locking member is locked, the avoiding opening is opposite to the stop valve. When the locking member is unlocked, the avoiding opening and the stop valve are staggered with each other. When the clamp is clamped, the stop valve can form a sealing state, so that the pot can normally generate high pressure to meet the high pressure cooking demand. When the clamp is unclamped, the stop valve remains in a pressure relief state, so as to prevent the pot from generating high pressure when the pressure cooker cover is not closed in place, and to ensure the safety of the pressure cooker cover.

[0016] Optionally, the two oppositely arranged locking members are respectively provided with the stop portion, and the two stop portions are spaced apart along the direction away from the locking member, so that the two stop portions can be respectively stopped on the opposite sides of the stop valve, increasing the stability of the stop valve.

[0017] The side surface of the two stop portions facing each other is a first surface, and the avoiding opening is recessed inwardly formed by the first surface. The two avoiding openings are collectively arranged around the outer periphery of the stop valve, so as to guide and limit the stop valve to a certain extent, reduce the possible shaking of the stop valve, and increase the stability of the lifting of the stop valve.

[0018] Optionally, the pressure cooker cover further comprises a shroud, which is detachably connected to the top of the cover body, and a part of the clamp is clamped between the shroud and the cover body, so that the clamp is reliably connected to the cover body and is prevented from falling off the cover body during use; the shroud extends along the surface of the cover body towards the axis of the cover body, and a channel is formed between the shroud and the cover body, in which the flexible traction member is arranged, so as to limit and guide the flexible traction member and prevent the flexible traction member from being damaged due to exposure, and the appearance of the pressure cooker cover is improved.

[0019] Optionally, the clamp assembly further comprises a cover head, which is connected to the center of the cover body, and each of the locking members is slidingly connected to the cover head, so as to reduce the number of parts and make full use of the internal space of the cover head and improve the compactness of the overall structure.

[0020] The second aspect of the present application provides a pressure cooker, which comprises a pot body and any one of the pressure cooker covers provided by the present application, and when the pressure cooker cover is connected to the pot body, the clamp can clamp the pressure cooker cover and the pot body at the same time. On the one hand, the distance between the locking member and the clamp can be set according to the size of the cover body, and only the length of the flexible traction member needs to be changed, so that the clamp assembly can be applied to cover bodies of various sizes; on the other hand, the flexible traction member can deform freely, so that the clamp assembly can adapt to cover bodies of various structural shapes. In addition, the clamp is kept in a clamped state by the locking member, which can effectively improve the stability of the clamp in achieving clamping and prevent the clamp from loosening accidentally due to external forces such as vibration or impact.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0063] In the description of the present application, it should be understood that the "upper", "lower" and other orientation words described in the embodiments of the present application are described with the angle shown in the 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 referring to an element connected to another element "on" or "below", it can not only be directly connected to another element "on" or "below", but also indirectly connected to another element "on" or "below" through an intermediate element.

[0064] As Figure 1As shown, the embodiment of the present application provides a pressure cooker, which comprises a pressure cooker cover 10 and a cooker body 20, and the pressure cooker cover 10 is detachably connected to the cooker body 20. Wherein, the pressure cooker cover 10 comprises a cover body 1 and a clamp assembly. The cover body 1 forms the main structure of the pressure cooker cover 10, and the cover body 1 is used to cover the cooker body 20; when the pressure cooker cover 10 is connected to the cooker body 20, the clamp assembly can clamp the pressure cooker cover 10 and the cooker body 20 at the same time, so as to realize the reliable connection of the pressure cooker cover 10 and the cooker body 20.

[0065] Wherein, the cover body 1 can be provided with a sealing ring, a pressure limiting valve and a stop valve 11. The sealing ring can form a sealed state between the pressure cooker cover 10 and the cooker body 20, so as to avoid the leakage of gas in the pot between the pressure cooker cover 10 and the cooker body 20. The pressure limiting valve is used to limit the maximum pressure in the pot, so as to ensure the safety of the pressure cooker. The stop valve 11 is provided through the cover body 1 and can be lifted along the cover body 1; when the stop valve 11 is lifted, a sealed state is formed between the stop valve 11 and the cover body 1, and high pressure can be formed in the pot; when the stop valve 11 is lowered, a pressure relief state is formed between the stop valve 11 and the cover body 1, and the pressure in the pot is released.

[0066] As shown, Figures 1-9 The clamp assembly comprises at least two clamps 2. The clamps 2 are arranged at the edge of the cover body 1 and can slide along the radial direction of the cover body 1 to realize clamping or canceling clamping. Specifically, the clamps 2 move towards the axis of the cover body 1 to realize clamping, and when the clamps 2 realize clamping, the clamps 2 clamp the pressure cooker cover 10 and the cooker body 20 at the same time, so as to reliably fix the pressure cooker cover 10 on the cooker body 20; the clamps 2 move away from the axis of the cover body 1 to cancel clamping, and when the clamps 2 cancel clamping, the pressure cooker cover 10 can be covered on the cooker body 20 or taken off from the cooker body 20.

[0067] Further, the clamp assembly further comprises at least two locking pieces 3 and a flexible traction piece 4 (for example, a metal wire, etc.). The locking pieces 3 are arranged at one side of the clamps 2 close to the axis of the cover body 1, and the flexible traction piece 4 connects the clamps 2 and the locking pieces 3; the locking pieces 3 can slide along the radial direction of the cover body 1 to realize locking or canceling locking. When the locking pieces 3 are close to each other, the locking pieces 3 can realize locking, the locking pieces 3 tighten the flexible traction piece 4, and the flexible traction piece 4 drives the clamps 2 to realize clamping; when the locking pieces 3 cancel locking, the locking pieces 3 can be away from each other, the locking pieces 3 loosen the flexible traction piece 4, and the clamps 2 can cancel clamping under the action of external force, etc.

[0068] The flexible traction member 4 is arranged between the clamp 2 and the locking member 3 to play a transmission role, so that the universality of the clamp assembly is improved, and the manufacturing cost of the pressure cooker is reduced. Specifically, on the one hand, the distance between the locking member 3 and the clamp 2 can be set according to the size of the cover body 1, and only the length of the flexible traction member 4 needs to be changed, so that the clamp assembly can be applied to cover bodies 1 of various sizes; on the other hand, since the flexible traction member 4 can deform freely, the clamp assembly can adapt to cover bodies 1 of various structural shapes. In addition, the clamp 2 is kept in a clamping state by the locking member 3, which can effectively improve the stability of the clamp 2 in achieving clamping and prevent the clamp 2 from loosening accidentally due to external forces such as vibration or impact.

[0069] Specifically, the flexible traction member 4 is arranged in one-to-one correspondence with the clamp 2, that is, each clamp 2 is connected with one flexible traction member 4. The locking member 3 can be arranged in one-to-one correspondence with the clamp 2, that is, each locking member 3 drives one clamp 2 to move; or the number of locking members 3 can be less than the number of clamps 2, that is, each locking member 3 can drive at least two clamps 2 to move. The locking member 3 can be slidably connected to the fixed component such as the cover body 1 or the cover head 6.

[0070] As shown in Figure 3 The clamp 2 and the cover body 1 can be provided with a first elastic member 21 (such as a spring), and the two ends of the first elastic member 21 are elastically abutted on the clamp 2 and the cover body 1, respectively, to force the clamp 2 to move away from the axis of the cover body 1. The user only needs to operate the locking member 3 to cancel the locking of the locking member 3 and release the flexible traction member 4, so that the clamp 2 can automatically move away from the axis of the cover body 1 under the action of the first elastic member 21, thereby canceling the clamping and improving the convenience of the operation of the pressure cooker cover 10.

[0071] Further, the clamp 2 can be provided with a first guide groove 22, and the extension direction of the first guide groove 22 is parallel to the movement direction of the clamp 2; the surface of the cover body 1 can be provided with a first guide column 12, the first guide column 12 is inserted into the first guide groove 22 and can slide along the length direction of the first guide groove 22, thereby playing a guiding role on the clamp 2 and increasing the stability of the movement of the clamp 2.

[0072] Further, the surface of the cover body 1 is provided with a first supporting part 13, the clamp 2 is provided with a second supporting part 23, and the first supporting part 13 and the second supporting part 23 are arranged in a radial direction of the cover body 1. One of the first supporting part 13 and the second supporting part 23 is provided with a bolt, and the other is provided with a hole. The bolt and the hole extend in the radial direction of the cover body 1, and the bolt and the hole form a sliding fit. The first supporting part 13 and the second supporting part 23 can guide the clamp 2 in the radial direction of the cover body 1, increase the stability of the movement of the clamp 2, and limit the clamp 2 in the axial direction of the cover body 1, reduce or avoid the up-and-down vibration of the clamp 2. In addition, the first elastic member 21 can be sleeved on the bolt, and the two ends of the first elastic member 21 can be elastically abutted on the first supporting part 13 and the second supporting part 23, respectively. The bolt guides and supports the first elastic member 21.

[0073] Reference Figures 4-6 In an embodiment, the number of the locking members 3 is two, and the two locking members 3 are arranged opposite to each other in the radial direction of the cover body 1. The two locking members 3 are buckled to each other to realize the locking. The cover body 1 and other components only provide installation and guidance for the locking members 3, and only need to adapt the shape of the locking members 3 to the cover head 6 and other components. The locking is formed between the two locking members 3, and does not depend on the cover head 6 and other components, which can improve the reliability of the locking of the locking members 3. In addition, the user can simultaneously apply an external force to the two locking members 3 by pinching, so that the two locking members 3 are close to each other to realize the locking, which improves the convenience of operation.

[0074] In the embodiment, a second elastic member 34 (for example, a spring) can be arranged between the two locking members 3. When the two locking members 3 are unlocked, the two locking members 3 are automatically away from each other and release the flexible traction member 4 under the action of the second elastic member 34, which further improves the convenience of operation of the pressure cooker cover 10.

[0075] Further, one of the lock members 3 is a first lock member 3a, and the other is a second lock member 3b. The axis of the lock member 3 refers to the line connecting the first lock member 3a and the second lock member 3b. The first lock member 3a is provided with a movable part 31, and the second lock member 3b is provided with a matching part 32. The movable part 31 moves (for example, slides or rotates, etc.) along the direction close to or away from the axis of the lock member 3. When the first lock member 3a and the second lock member 3b are close to each other, the movable part 31 and the matching part 32 are stacked along the direction close to or away from the axis of the lock member 3. The movable part 31 and the matching part 32 are buckled to each other to achieve locking. That is, the matching part 32 is located on one side of the movable part 31 along the direction of its own movement, so that the movable part 31 can move towards the matching part 32 to achieve buckling, and the movable part 31 can move away from the matching part 32 to cancel the buckling. The buckling depth of the movable part 31 and the matching part 32 is limited by the movement stroke of the movable part 31, which can ensure the reliability of the buckling while avoiding large stress between the movable part 31 and the matching part 32, thereby prolonging the service life of the lock member 3. Understandably, in other embodiments, the first lock member 3a can be provided with a resilient buckle, which is close to or away from the matching part 32 by deforming itself, thereby achieving buckling or canceling buckling.

[0076] Further, one end of the movable part 31 is pivotally connected to the first lock member 3a, and the other end extends towards the second lock member 3b. That is, the movable part 31 rotates towards or away from the axis of the lock member 3 to reduce the movement resistance of the movable part 31 and increase the stability of the action of the movable part 31.

[0077] Among them, the first lock member 3a is provided with a third elastic member 35 (for example, a spring, etc.), which is arranged on the side of the movable part 31 away from the matching part 32. The third elastic member 35 elastically abuts against the movable part 31 to force the movable part 31 to move towards the matching part 32, so that when the first lock member 3a and the second lock member 3b are close to each other, the movable part 31 and the matching part 32 can automatically achieve buckling without manually operating the movement of the movable part 31, thereby improving the convenience of operation.

[0078] Specifically, among the movable part 31 and the matching part 32, one is provided with a clamping protrusion 311, and the other is provided with a clamping groove 321. The clamping protrusion 311 protrudes along the stacking direction of the movable part 31 and the matching part 32, and the clamping groove 321 is recessed along the stacking direction of the movable part 31 and the matching part 32. When the movable part 31 and the matching part 32 are stacked with each other, the clamping protrusion 311 buckles in the clamping groove 321, so that the lock member 3 achieves locking. The clamping groove 321 can be provided as a through groove to ensure that the clamping protrusion 311 can be completely clamped into the clamping groove 321, avoiding interference of the clamping groove 321 with the clamping protrusion 311 in the depth direction.

[0079] Further, one side of the at least one locking piece 3 extends a stop portion 33, the extending direction of the stop portion 33 is parallel to the moving direction of the locking piece 3; at least one part of the stop portion 33 is above the stop valve 11, and the stop portion 33 is provided with an avoiding opening 331. When the locking piece 3 realizes locking (see Figure 5 ), the avoiding opening 331 is opposite to the stop valve 11, and the stop valve 11 can pass through the avoiding opening 331 to rise, that is, when the clamp 2 realizes clamping, the stop valve 11 can form a sealing state, so that the pot can normally generate high pressure, meeting the high pressure cooking demand; when the locking piece 3 cancels the locking (see Figure 4 ), the avoiding opening 331 is staggered with the stop valve 11, and the stop valve 11 is stopped below the stop portion 33 and cannot rise, that is, when the clamp 2 cancels clamping, the stop valve 11 remains in a pressure relief state, thereby preventing the pot from generating high pressure when the pressure cooker cover 10 is not closed in place, and ensuring the use safety of the pressure cooker cover 10.

[0080] In addition, when the pot is in a high pressure state, the clamp 2 is in a state of realizing clamping, the stop valve 11 rises and is provided in the avoiding opening 331, at this time, the stop valve 11 is stopped on the inner wall of the avoiding opening 331, thereby playing a limiting role on the locking piece 3, so that the locking piece 3 cannot move away from each other, and the clamp 2 cannot cancel clamping, ensuring that the clamp 2 reliably remains in a clamping state under high pressure, preventing the pressure cooker cover 10 from being opened accidentally under high pressure.

[0081] Among them, the avoiding opening 331 can be provided in a closed structure, that is, the avoiding opening 331 is provided with a gap with the edge of the stop portion 33. The avoiding opening 331 can also be provided in an open structure, that is, the avoiding opening 331 is formed by the edge of the stop portion 33 being concave inwardly.

[0082] In one embodiment, the two locking pieces 3 arranged oppositely are respectively provided with the stop portion 33, and the two stop portions 33 are arranged in a spaced manner along the direction away from the locking piece 3, so that the two stop portions 33 can be respectively stopped on the opposite sides of the stop valve 11, increasing the stability of the stop valve 11. The side surface of the two stop portions 33 facing each other is a first surface, and the avoiding opening 331 is formed by the first surface being concave inwardly, and the two avoiding openings 331 are collectively arranged around the outer periphery of the stop valve 11, thereby playing a certain guiding and limiting role on the stop valve 11, reducing the possible shaking of the stop valve 11, and increasing the stability of the lifting of the stop valve 11.

[0083] As Figures 6-9As shown, the clamp assembly also includes an unlocking member 5. The unlocking member 5 is located on the side of the movable part 31 facing the mating part 32 and can move towards or away from the axis of the locking member 3. For example, the unlocking member 5 can be slidably connected to a fixed component such as the cover 1 or the cover head 6. When the movable part 31 and the mating part 32 are engaged, a portion of the movable part 31 protrudes outside the mating part 32. The unlocking member 5 abuts against the exposed portion of the movable part 31 to push the movable part 31 away from the mating part 32, thereby releasing the engagement between the movable part 31 and the mating part 32, and thus releasing the engagement between the first locking member 3a and the second locking member 3b. The unlocking member 5 is shaped for easy pressing, improving the user's ease of operation.

[0084] The unlocking member 5 has a fourth elastic element 51 (e.g., a spring) on ​​the side facing the movable part 31. The fourth elastic element 51 elastically abuts against the unlocking member 5, forcing the unlocking member 5 to move away from the movable part 31, thereby enabling the unlocking member 5 to automatically reset. The unlocking member 5 and the locking member 3 are connected to the same mounting base. For example, both the unlocking member 5 and the locking member 3 are slidably connected to the cover head 6, and the movement direction of the unlocking member 5 is perpendicular to the movement direction of the locking member 3, further improving the compactness of the overall structure.

[0085] In one embodiment, the movable part 31 is provided with a latching protrusion 311, and the mating part 32 is provided with a latching groove 321, which is configured as a through groove penetrating the mating part 32. The unlocking member 5 and the movable part 31 are respectively located on opposite sides of the mating part 32, and the unlocking member 5 and the latching protrusion 311 pass through the latching groove 321 and abut against each other. On the one hand, the unlocking member 5 directly abuts against and pushes the latching protrusion 311, causing the latching protrusion 311 to disengage from the latching groove 321, which makes the operation of the unlocking member 5 more effortless and efficient. On the other hand, the unlocking member 5 and the movable part 31 abut against each other within the range of the mating part 32, which can make the external shape of the locking member 3 more regular and the overall structure of the pressure cooker lid 10 more compact.

[0086] Furthermore, a notch 322 is provided on one side of the slot 321 to pass through the mating part 32, so as to avoid the unlocking member 5, ensuring that after the moving part 31 and the mating part 32 are released from the latch, the two locking members 3 can move away from each other smoothly, preventing the unlocking member 5 from interfering with the slot wall of the slot 321 during the movement of the locking member 3.

[0087] like Figures 7-9 As shown, the clamp assembly also includes a lid 6. The lid 6 can be connected to the center of the lid body 1 by means of screws or the like, so as to facilitate the user to hold and lift the pressure cooker lid 10. Each locking element 3 is slidably connected to the lid 6, and the lid 6 forms a mounting seat for the locking elements 3, which can reduce the number of parts and make full use of the internal space of the lid 6, thereby improving the compactness of the overall structure.

[0088] Further, the pressure cooker cover 10 further comprises a shroud 7. The shroud 7 is detachably connected to the upper portion of the cover body 1, for example, the shroud 7 is connected to the guide column of the cover body 1 by means of screws or other fasteners. A portion of the clamp 2 is clamped between the shroud 7 and the cover body 1, thereby reliably connecting the clamp 2 to the cover body 1 and preventing the clamp 2 from falling off the cover body 1 during use.

[0089] Further, the shroud 7 extends along the surface of the cover body 1 in a direction close to the axis of the cover body 1, and the shroud 7 and the surface of the cover body 1 jointly define a channel 71. The flexible traction member 4 is arranged in the channel 71, which can limit and guide the flexible traction member 4 and prevent the flexible traction member 4 from being exposed and damaged, and can also improve the appearance of the pressure cooker cover 10.

[0090] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
