Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a pressure cooker cover and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking appliance. Its main function is to increase the heating temperature by increasing the air pressure in the pot, thereby increasing the heating speed. The pressure cooker is mainly composed of a pressure cooker lid and a pot body. The pressure cooker lid and the pot body are connected by a clamp. The clamp can move relative to the pot body to achieve the clamping or unclamping of the pressure cooker lid and the pot body at the same time. However, the existing clamp device usually adopts a rotating method to achieve clamping or unclamping. During operation, the pot lid or the pot body is easy to rotate synchronously, which makes it inconvenient to open and close the pressure cooker lid, affecting the user experience of the pressure cooker. Utility Model Content

[0003] The present application provides a pressure cooker cover and a pressure cooker, so as to solve the technical problem of inconvenient operation of opening and closing the pressure cooker cover and improve the user experience of the pressure cooker.

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

[0005] Supports;

[0006] Two clamps, the clamps are slidably connected to the support member and can slide along the radial direction of the cover body, the clamps are provided with a slide groove, and the extension direction of the slide groove is inclined relative to the movement direction of the clamps;

[0007] A driving member, pivotally connected to the supporting member, wherein the rotating shaft of the driving member is provided with a toggle block, and the toggle block protrudes from the surface of the rotating shaft along the radial direction of the rotating shaft;

[0008] The toggle block cooperates with the slide slot to convert the flipping motion of the driving member into the sliding motion of the clamp.

[0009] The pressure cooker cover provided in the present application includes a detachably connected cover body and a clamp device, and the clamp device includes a support member, two clamps and a driving member; the support member is used to connect the cover body, that is, the support member forms the main part of the clamp device, and the other components of the clamp device are installed on the support member, so that the clamp device can be used as a whole and can be detachably connected to the cover body, thereby facilitating disassembly, assembly, cleaning and maintenance; the clamp is slidably connected to the support member and can slide along the radial direction of the cover body to achieve clamping and unclamping, and the clamp is provided with a slide groove, and the extension direction of the slide groove is inclined relative to the movement direction of the clamp; the driving member is pivotally connected to the support member, and the rotating shaft of the driving member is provided with a toggle block, which protrudes from the surface of the rotating shaft along the radial direction of the rotating shaft; the toggle block cooperates with the slide groove to convert the flipping movement of the driving member into the sliding of the clamp, that is, the user only needs to flip the driving member up and down to drive the clamp to achieve clamping or unclamping, which is simple and labor-saving to operate, and improves the user experience of the pressure cooker.

[0010] Optionally, the toggle block is a columnar structure, and the toggle block and the rotating shaft are perpendicular to each other to ensure that the interaction force between the toggle block and the clamp is located in the planar extension direction of the cover body, thereby avoiding the toggle block from generating a component force along the axial direction of the cover body, thereby allowing the clamp to slide stably along the surface of the cover body.

[0011] Optionally, the driving member includes a gripping portion to facilitate a user to apply an external force to the driving member; the gripping portion and the toggle block are arranged at intervals around the circumference of the rotating shaft, and the angle α between the gripping portion and the toggle block is an obtuse angle, so that a larger gripping space can be formed on both sides of the gripping portion, thereby ensuring the convenience of user gripping.

[0012] Optionally, the angle α between the gripping portion and the toggle block is 130° to 140°, so that the swing amplitude of the toggle block to both sides is basically the same, so that the clamp is more evenly stressed along its own width direction, preventing unilateral wear of the clamp caused by uneven force, and effectively extending the service life of the clamp.

[0013] Optionally, a flange is provided around the edge of the slide slot. On the one hand, the effective matching depth between the toggle block and the slide slot is increased without increasing the overall thickness of the clamp, thereby further increasing the stability and reliability of the mutual cooperation between the toggle block and the clamp; on the other hand, the edge strength of the slide slot is increased to prevent the edge of the slide slot from being deformed or damaged, thereby increasing the stability of the mutual cooperation between the toggle block and the clamp.

[0014] Optionally, the slide groove penetrates the clamp along the thickness direction of the clamp. On the one hand, it can avoid the thickness of the clamp from limiting the movement stroke of the toggle block, prevent the bottom of the slide groove from interfering with the movement trajectory of the toggle block, and affect the normal flipping movement of the driving member; on the other hand, it can ensure that the effective matching depth of the toggle block and the slide groove remains unchanged, thereby increasing the stability and reliability of the mutual cooperation between the toggle block and the clamp, and preventing the toggle block and the clamp from slipping off each other.

[0015] Optionally, the cover includes a concave structure, the concave structure is located below the driving member, an escape space is formed above the concave structure, and at least a portion of the toggle block passes through the slide slot and extends into the escape space. Without changing the overall matching state of the clamp device and the cover, sufficient movement space is formed between the clamp device and the cover to prevent the cover surface and the movement trajectory of the toggle block from interfering with each other and affecting the normal flipping movement of the driving member.

[0016] Optionally, the clamp includes: an extension portion, the extension portion extends along the radial direction of the cover body; a transmission portion, the transmission portion is located at one end of the extension portion close to the axis of the cover body; the height of the transmission portion is higher than the height of the extension portion, and the slide groove is arranged on the transmission portion. On the one hand, the extension portion is close to the cover body, thereby improving the compactness of the fit between the clamp device and the cover body and reducing the overall volume of the pressure cooker cover; on the other hand, the transmission portion is far away from the cover body, which can reduce the distance between the clamp and the rotating shaft, ensuring that the toggle block and the clamp form a stable and reliable fit.

[0017] Optionally, the width of the transmission part is greater than the width of the extension part to increase the swing range of the toggle block and reduce the movement resistance of the toggle block, thereby making the operation of the drive member more labor-saving and preventing accidents such as jamming or self-locking between the toggle block and the slide slot.

[0018] Optionally, the cover body is provided with a check valve, which is passed through the cover body and can be raised and lowered along the axial direction of the cover body; the clamp is provided with a through slot, the check valve is passed through the through slot and can slide relatively along the through slot, and the through slot includes an avoidance section and a locking section connected to each other; when the clamp is clamped, the check valve is located in the avoidance section, and the check valve can pass through the avoidance section and rise and fall freely; when the clamp is unclamped, the check valve is located in the locking section, and the check valve stops at the locking section and cannot rise and fall. When the pressure cooker lid is tightly closed on the pot body, the clamp releases the check valve, so that high pressure can be normally formed in the pot, meeting the high-pressure cooking requirements of the pressure cooker; when the pressure cooker lid is not tightly closed on the pot body, the clamp locks the check valve, so that high pressure cannot be formed in the pot, ensuring the safety of the pressure cooker.

[0019] 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.

[0050] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0051] In order to make the objectives, technical solutions and advantages of this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0052] In the description of this application, unless otherwise clearly specified and defined, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "plural" means two or more; the terms "connection", "fixation", etc. should all be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in this application can be understood according to specific circumstances.

[0053] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the drawings and should not be construed as limitations on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0054] As Figures 1 - 8 shown, the embodiments of this application provide a pressure cooker lid that can be closed on the pot body and form a pressure cooker together with the pot body. The pressure cooker lid includes a detachable 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. When the pressure cooker lid is connected to the pot body, the clamp device 2 can simultaneously clamp the pressure cooker lid and the pot body, thereby realizing a reliable connection between the pressure cooker lid and the pot body; the cover body 1 is provided with a sealing ring, a pressure limiting valve 3 and a safety valve 4; the sealing ring can form a sealed state between the pressure cooker lid and the pot body to prevent gas in the pot from leaking between the pressure cooker lid and the pot body; the pressure limiting valve 3 is used to limit the maximum pressure in the pot; the safety valve 4 penetrates through the pressure cooker lid and can move up and down along the pressure cooker lid. When the safety valve 4 rises, a sealed state is formed and high pressure can be formed in the pot; when the safety valve 4 descends, a pressure relief state is formed and the pressure in the pot is released.

[0055] Further, the clamp device 2 includes a support member 21, two clamps 22 and a driving member 23. The support member 21 is used to connect the cover body 1. That is to say, the support member 21 forms the main body part of the clamp device 2, and other components of the clamp device 2 are all installed on the support member 21, so that the clamp device 2 can be used as a whole and is detachably connected to the cover body 1, thus facilitating disassembly, assembly, cleaning and maintenance; the clamps 22 are slidably connected to the support member 21 and can slide in the radial direction of the cover body 1 to realize clamping and releasing clamping; the driving member 23 is connected to the support member 21, and the driving member 23 drives the clamps 22 to move in the direction close to the axis of the cover body 1 to realize clamping, and the driving member 23 drives the clamps 22 to move in the direction away from the axis of the cover body 1 to release clamping. The driving member 23 directly interacts with the clamps 22 without being transmitted through other intermediate components, improving the force transmission efficiency and the stability of the movement of the clamps 22.

[0056] Specifically, the support member 21 is centered on the axis of the cover body 1. A cavity extending radially along the cover body 1 is provided at the edge of the support member 21. A part of the clamp 22 is accommodated in the cavity and can slide along the cavity. For the convenience of installing the clamp 22, the support member 21 can be set as a first part 21a and a second part 21b that are fitted together. 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 means such as screws.

[0057] As Figure 2 and Figure 3 shown, further, the clamp 22 is provided with a chute 221. The extending direction of the chute 221 is inclined with respect to the moving direction of the clamp 22. For example, the chute 221 can extend along an inclined direction or along an arc direction, so that the chute 221 can form a component motion parallel to the moving direction of the clamp 22 and a component motion perpendicular to the moving direction of the clamp 22. The driving member 23 is pivotally connected to the support member 21. A toggle block 232 is provided on the rotating shaft 231 of the driving member 23. The toggle block 232 protrudes radially from the surface of the rotating shaft 231 along the rotating shaft 231. The toggle block 232 cooperates with the chute 221 to convert the flipping motion of the driving member 23 into the sliding motion of the clamp 22. That is to say, the user only needs to flip the driving member 23 up and down to drive the clamp 22 to achieve clamping or cancel clamping, which is simple and labor-saving in operation and improves the use experience of the pressure cooker.

[0058] Specifically, the extending direction of the rotating shaft 231 of the driving member 23 is parallel to the moving direction of the clamp 22. The driving member 23 can perform a flipping motion relative to the support member 21, so that the driving member 23 can move toward the support member 21 to a storage state (the driving member 23 is substantially in a horizontal state), and the driving member 23 can move away from the support member 21 to an open state (the driving member 23 is substantially in a vertical state). The toggle block 232 is correspondingly arranged with the clamp 22. The chutes 221 of the two clamps 22 are symmetrically arranged, and the two toggle blocks 232 are symmetrically arranged, so that the two clamps 22 can move synchronously and in opposite directions, thereby achieving clamping and canceling clamping.

[0059] Further, the toggle block 232 is a columnar structure, which is simple in structure and easy to process and form, and can reduce the mutual contact area between the toggle block 232 and the chute 221, thereby reducing the resistance of the relative motion between the two, making the operation of the driving member 23 more labor-saving. The toggle block 232 is perpendicular to the rotating shaft 231 to ensure that the mutual acting force between the toggle block 232 and the clamp 22 is in the plane extension direction of the cover body 1, avoiding the generation of a component force along the axis of the cover body 1 by the toggle block 232, so that the clamp 22 can stably slide along the surface of the cover body 1. It can be understood that in other embodiments, the toggle block 232 can also be inclined with respect to the rotating shaft 231.

[0060] Furthermore, the slide groove 221 penetrates the clamp 22 along the thickness direction of the clamp 22. On the one hand, it can avoid the thickness of the clamp 22 from limiting the movement stroke of the toggle block 232, and prevent the groove bottom of the slide groove 221 and the movement trajectory of the toggle block 232 from interfering with each other, thereby affecting the normal flipping movement of the driving member 23; on the other hand, it can ensure that the effective matching depth of the toggle block 232 and the slide groove 221 remains unchanged, thereby increasing the stability and reliability of the mutual cooperation between the toggle block 232 and the clamp 22, and preventing the toggle block 232 and the clamp 22 from slipping off each other.

[0061] Furthermore, a flange 222 is provided around the edge of the slide groove 221. On the one hand, without increasing the overall thickness of the clamp 22, the effective matching depth between the toggle block 232 and the slide groove 221 is increased, thereby further increasing the stability and reliability of the mutual cooperation between the toggle block 232 and the clamp 22; on the other hand, the edge strength of the slide groove 221 is increased to prevent the edge of the slide groove 221 from being deformed or damaged, thereby increasing the stability of the mutual cooperation between the toggle block 232 and the clamp 22. In addition, by providing the flange 222, the slide groove 221 forms a smooth wall surface, reducing the contact stress between the toggle block 232 and the slide groove 221, thereby preventing the toggle block 232 from being deformed or damaged, and increasing the stability of the mutual cooperation between the toggle block 232 and the clamp 22.

[0062] Furthermore, the cover body 1 includes a concave structure 11, which is located below the driving member 23, and an escape space is formed above the concave structure 11, and at least a portion of the toggle block 232 passes through the slide slot 221 and extends into the escape space. Without changing the overall matching state of the clamping device 2 and the cover body 1, sufficient movement space is formed between the clamping device 2 and the cover body 1 to prevent the surface of the cover body 1 and the movement trajectory of the toggle block 232 from interfering with each other and affecting the normal flipping movement of the driving member 23. It can be understood that in other embodiments, sufficient movement space can also be formed between the clamping device 2 and the cover body 1 by raising the height of the clamping device 2 as a whole.

[0063] like Figures 4 - 8 As shown, further, the clamp 22 includes an extension portion 22a, a transmission portion 22b and a clamping portion 22c. The extension portion 22a extends along the radial direction of the cover body 1; the transmission portion 22b is located at one end of the extension portion 22a close to the axis of the cover body 1, and the slide groove 221 is provided on the transmission portion 22b, that is, the transmission portion 22b is used to connect the driving member 23; the clamping portion 22c is located at one end of the extension portion 22a away from the axis of the cover body 1, and the clamping portion 22c is used to clamp the pressure cooker cover and the cooker body.

[0064] Furthermore, the height of the transmission part 22b is higher than that of the extension part 22a, that is, the transmission part 22b and the extension part 22a are mutually staggered along the axial direction of the cover body 1, and the transmission part 22b is farther away from the cover body 1 than the extension part 22a. On the one hand, the extension part 22a is close to the cover body 1, thereby improving the compactness of the fit between the clamp device 2 and the cover body 1 and reducing the overall volume of the pressure cooker cover; on the other hand, the transmission part 22b is far away from the cover body 1, which can reduce the distance between the clamp 22 and the rotating shaft 231, ensuring that the toggle block 232 and the clamp 22 form a stable and reliable fit.

[0065] Specifically, a transition portion is provided between the extension portion 22a and the transmission portion 22b. Along the direction of the extension portion 22a pointing to the transmission portion 22b, the transition portion gradually tilts away from the cover body 1. For example, the transition portion can be provided as any appropriate structure such as an inclined surface, an arc surface or a stepped surface.

[0066] Furthermore, the width of the transmission portion 22b is greater than the width of the extension portion 22a, so as to increase the swing range of the toggle block 232 and reduce the movement resistance of the toggle block 232, thereby making the operation of the driving member 23 more labor-saving and preventing accidents such as jamming or self-locking between the toggle block 232 and the slide slot 221.

[0067] Furthermore, the driving member 23 includes a gripping portion 233, which can be configured in any shape such as an arcuate shape that is convenient for the user to grip, so as to facilitate the user to apply an external force to the driving member 23. The gripping portion 233 and the toggle block 232 are arranged at intervals around the circumference of the rotating shaft 231, and the angle α between the gripping portion 233 and the toggle block 232 is an obtuse angle (refer to Figure 5 , that is, 90°<α<180°), so that both sides of the grip portion 233 can form a larger gripping space to ensure the convenience of the user's grip. When the angle α between the grip portion 233 and the toggle block 232 is less than 90°, the grip portion 233 has a smaller space on the side where the angle α is located, and as the grip portion 233 flips, the space will further decrease, making it difficult for the user to grip the grip portion 233.

[0068] Furthermore, the angle α between the grip portion 233 and the toggle block 232 is 130° to 140° (refer to Figure 5 ), for example, the angle between the gripping portion 233 and the toggle block 232 can be 130°, 132°, 135°, 138° or 140°, etc., so that the swing amplitude of the toggle block 232 to both sides is basically the same, so that the force on the clamp 22 along its own width direction is more uniform, preventing unilateral wear of the clamp 22 caused by uneven force, and effectively extending the service life of the clamp 22.

[0069] Further, the pressure relief valve 4 is inserted through the cover body 1 and can move up and down along the axial direction of the cover body 1; the clamp 22 is provided with a through groove, and the pressure relief valve 4 is inserted through the through groove and can slide relative to the through groove. The through groove includes an avoidance section 223 and a locking section 224 which are connected to each other. The width of the locking section 224 is smaller than that of the avoidance section 223. When the clamp 22 is tightened (refer to Figure 4 and Figure 6 ), the pressure relief valve 4 is located in the avoidance section 223, and the pressure relief valve 4 can freely move up and down through the avoidance section 223. That is to say, when the pressure cooker cover tightly covers the pot body, the clamp 22 releases the pressure relief valve 4, so that high pressure can be normally formed in the pot, meeting the high-pressure cooking requirements of the pressure cooker; when the clamp 22 releases the tightening (refer to Figure 7 and Figure 8 ), the pressure relief valve 4 is located in the locking section 224, and the pressure relief valve 4 is blocked by the locking section 224 and cannot move up and down. That is to say, when the pressure cooker cover does not tightly cover the pot body, the clamp 22 locks the pressure relief valve 4, so that high pressure cannot be formed in the pot, ensuring the safe use of the pressure cooker.

[0070] In addition, the embodiment of the present application also provides a pressure cooker, which includes a pot body and any one of the pressure cooker covers provided by the embodiment of the present application. When the pressure cooker cover is connected to the pot body, the clamp device 2 can simultaneously clamp the pressure cooker cover and the pot body.

[0071] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. 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.
