Description

Technical Field

[0001] This utility model relates to the field of pressure cooker technology, specifically to clamp assembly, pot lid and pressure cooker. Background Technology

[0002] The pot body and lid of a clamp-type pressure cooker are locked together by a clamp assembly. The clamp assembly is generally located on the lid. In related technologies, clamp assemblies are generally divided into integral and separate types. Integral clamp assemblies are inconvenient to assemble with the lid, while separate clamp assemblies generally require connection through connectors, which increases the number of parts on the lid and makes assembly inconvenient.

[0003] Therefore, it is essential to design a clamp structure that is easy to assemble. Utility Model Content

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a clamp assembly, a pot lid, and a pressure cooker, which have the advantage of convenient installation.

[0005] To achieve the above objectives, the first aspect of this utility model discloses a clamping assembly, including a clamping member and a sliding member. The clamping member is used to lock and engage with a pot body, and the sliding member is used to slide on a pot lid. A second mating portion is formed on the sliding member, and a clamping mating portion corresponding to the second mating portion is formed on the clamping member. The clamping mating portion and the second mating portion are engaged with each other so that the sliding member and the clamping member are detachably connected.

[0006] In this technical solution, by setting the clamp assembly as a split structure (slider and clamping component), compared with the integral type, the shape and material of the slider and clamping component can be reasonably designed according to different functions and usage scenarios during actual production, which can reduce production costs. In addition, the slider and clamping component are connected by a snap-fit ​​structure, eliminating the need for additional connecting parts and reducing the number of parts in the clamp assembly.

[0007] Furthermore, the second docking part includes a docking body and a snap-fit ​​boss protruding from the surface of the docking body. The clamping docking part includes a snap-fit ​​hole adapted to the snap-fit ​​boss. The snap-fit ​​boss is inserted into the snap-fit ​​hole. The length dimension of the snap-fit ​​hole and the snap-fit ​​boss is greater than the width dimension.

[0008] Furthermore, the second docking part also includes two limiting buckles, which are disposed on opposite sides of the snap-fit ​​protrusion. One end of each limiting buckle is connected to the docking body, and the other end forms a protrusion opposite to the surface of the docking body. The clamping docking part includes a clamping body, and the snap-fit ​​hole is disposed on the clamping body. The clamping body is disposed between the two limiting buckles and is clamped and fixed by the protrusion and the docking body.

[0009] Furthermore, the clamping member includes a clamping section and a connecting section. The clamping section is used to lock and engage with an external component. The connecting section has the clamping mating portion formed on it. The clamping section is arc-shaped, and the connecting section is located in the middle part of the arc of the clamping section.

[0010] Furthermore, the clamping section includes a top plate, a vertical plate, and a bottom plate. The top plate, vertical plate, and bottom plate are all constructed in an arc shape. The bottom plate is located at the bottom of the vertical plate and is spaced apart from the top plate. The connecting section is located at the middle position of the arc of the top plate. The vertical plate and the bottom plate have discharge ports corresponding to the connecting section.

[0011] Furthermore, the clamping member is made of metal, and the sliding member is made of plastic;

[0012] And / or, the slider further includes a sliding support portion and a first docking portion, the first docking portion and the second docking portion being respectively disposed at opposite ends of the sliding support portion, the sliding support portion being used to slide in connection with an external component, and the first docking portion being used to connect with a drive assembly.

[0013] The second aspect of this utility model discloses a pot lid, which includes an inner lid and an outer lid, the inner lid and the outer lid being stacked and connected, with an installation space formed between the inner lid and the outer lid. The pot lid also includes a driving assembly and a plurality of clamping assemblies circumferentially distributed around the axis of the pot lid. At least one of the clamping assemblies is the clamping assembly described in the first aspect. The sliding member is located within the installation space and is slidably disposed on the inner lid along the radial direction of the pot lid. The output end of the driving assembly is connected to the sliding member and is used to drive the plurality of clamping assemblies to move synchronously inward and outward along the radial direction of the pot lid, and to enable the clamping member to extend out of the installation space and lock with the outer wall of the pot body.

[0014] In this technical solution, the clamp assembly is designed as a split structure, which facilitates the assembly of the clamp assembly with the pot lid during use and allows for targeted structural design for different functions in different parts. The clamping and sliding parts in this application are snap-fitted together, which is different from the split structure of the clamp assembly in related technologies that uses a bolt connection. This eliminates the need for separate connecting parts, reduces the number of parts in the pot lid, and facilitates assembly.

[0015] Furthermore, one of the inner cover and the outer cover is provided with a guide mechanism located within the installation space. The guide mechanism includes two baffles that are arranged relatively apart, and a radial sliding channel is formed between the two baffles. The sliding member is slidably disposed between the two baffles, and the two sides of the sliding member are respectively attached to the two baffles.

[0016] Furthermore, the drive assembly includes an operating knob and a drive gear. The operating knob is rotatably disposed on the outer cover, and the top of the operating knob protrudes from the back of the outer cover. The drive gear is fixedly connected to the operating knob and is located between the two clamping assemblies. A rack is formed on the inner end of the sliding member that meshes with the drive gear. The racks on the two sliding members are located on opposite sides of the drive gear.

[0017] Furthermore, the drive assembly includes an operation knob and a drive disk. The operation knob is rotatably mounted on the outer cover, and the top of the operation knob protrudes from the back of the outer cover. The drive member is fixedly connected to the operation knob. Two circumferentially extending drive grooves are formed on the drive disk. The distance between each point on the drive groove and the axis of the drive disk gradually changes circumferentially. A connecting post is formed on the inner side of the sliding member, and the connecting post extends into the drive groove.

[0018] The third aspect of this utility model discloses a pressure cooker, including a pot body and a pot lid. The pot lid adopts the pot lid of the first aspect. An outer wall protrusion is formed on the outer wall of the open end of the pot body. When the pot lid is placed on the pot body, the driving assembly can drive the clamping assembly to move radially inward and outward along the pot lid, and can make the clamping member extend to the bottom side of the outer wall protrusion.

[0019] The reasoning process for the beneficial effects of the pressure cooker provided by this utility model and the aforementioned pot lid is similar, and will not be repeated here.

[0020] These features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings.

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0043] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0044] See appendix Figures 6 to 11 One embodiment of this utility model discloses a clamp assembly, including a clamping member 141 and a sliding member 142. The clamping member 141 is used to lock into a pot body, and the sliding member is used to slide with a pot lid. A second mating portion 1424 is formed on the sliding member 142, and a clamping mating portion corresponding to the second mating portion 1424 is formed on the clamping member 141. The clamping mating portion and the second mating portion 1424 are engaged with each other so that the sliding member 142 and the clamping member 141 are detachably connected.

[0045] The clamp assembly 14 in this embodiment is generally used on the lid of a clamp-type pressure cooker. In use, the clamp assembly is generally slidably connected to the lid via the sliding member 142. The clamping member 141 can lock or unlock with the pot body by sliding inward and outward on the lid. This embodiment does not specifically limit the specific structure of the lid. The lid can be a double-layer lid or a single-layer lid. As long as the clamp assembly mentioned in this embodiment is used, it should be considered to fall within the scope of this application.

[0046] In this embodiment, the clamping component 141 and the sliding component 142 are separate structures. This allows for the design of the specific structure of each component and the selection of appropriate materials during production, based on the actual scenario, to achieve their respective functions. For example, the main function of the clamping component 141 is to lock and engage with the pot body, requiring greater strength, so it can be made of metal. The main function of the sliding component 142 is to serve as the mounting base and for sliding, so it can be made of plastic. It can be seen that compared to the structure of an integral clamping assembly, the clamping assembly 14 in this embodiment allows for more targeted material selection, thereby reducing production costs.

[0047] Furthermore, in this embodiment, the clamping member 141 and the sliding member 142 are snapped together, which reduces the number of components compared to the separate clamping assemblies in the prior art that are connected by connectors (generally bolts, rivets, etc.).

[0048] As one embodiment of this utility model, see the appendix. Figures 6 to 11 The second docking part 1424 includes a docking body 14241 and a snap-fit ​​boss 14242 protruding from the surface of the docking body 14241. The clamping docking part includes a snap-fit ​​hole 14121 adapted to the snap-fit ​​boss 14242. The snap-fit ​​boss 14242 is inserted into the snap-fit ​​hole 14121. The length dimension of the snap-fit ​​hole 14121 and the snap-fit ​​boss 14242 is greater than the width dimension.

[0049] In this embodiment, the sliding member 142 and the clamping member 141 are detachably connected via the second mating part 1424 and the clamping member 141. The locking boss 14242 and the locking hole 14121 are interlocked, and the length of the locking hole 14121 and the locking boss 14242 is greater than the width, similar to an elongated hole structure. Thus, when they are interlocked, the sliding member 142 and the clamping member 141 will not move relative to each other in the circumferential direction. That is, the engagement between the locking hole 14121 and the locking boss 14242 in this embodiment not only has a connecting function but also a limiting function.

[0050] It should be noted that the shapes of the snap-fit ​​hole 14121 and the snap-fit ​​boss 14242 in this embodiment can be set as square or flat. Of course, matching keyways and key mating structures can also be provided on the snap-fit ​​hole 14121 and the snap-fit ​​boss 14242, as long as the two can be restricted to move relative to each other in the circumferential direction when they are inserted into each other.

[0051] As one embodiment of this utility model, see the appendix. Figures 6 to 11 The second docking part 1424 further includes two limiting buckles 14243. The two limiting buckles 14243 are disposed on opposite sides of the snap-fit ​​protrusion 14242. One end of the limiting buckle 14243 is connected to the docking body 14241, and the other end forms a protrusion opposite to the surface of the docking body 14241. The clamping docking part includes a clamping body. The snap-fit ​​hole 14121 is disposed on the clamping body. The clamping body is disposed between the two limiting buckles 14243 and is clamped and fixed by the protrusion and the docking body 14241.

[0052] In this embodiment, the limiting buckle 14243 can cooperate with the docking body 14241 to clamp and fix the docking part of the clamping member 141, thereby limiting the vertical movement of the clamping member 141 and the sliding member 142. The structure of the limiting buckle 14243 cooperating with the locking boss 14242 makes the connection between the sliding member 142 and the clamping member 141 more reliable. It also realizes that the clamping member 141 and the sliding member 142 are connected by their own structure without the need for additional connecting parts, thereby further reducing the number of parts required for the pot lid 10 in this utility model.

[0053] For example, when the slider 142 is made of plastic and the clamping member 141 is made of metal, the size of the snap-fit ​​hole 14121 can be set to be slightly smaller than the size of the snap-fit ​​boss 14242. During installation, the snap-fit ​​boss 14242 will deform to a certain extent (plastic parts are easily deformed) and then be inserted into the snap-fit ​​hole 14121, which can improve the stability of the connection. Moreover, the limiting buckle 14243 can also be set to be a structure that fits more tightly with the clamping member 141 (the plastic part will deform to a certain extent under force and assemble with the clamping member 141), which can improve the reliability of the assembly of the clamping member 141 and the slider 142.

[0054] In one embodiment of the present invention, the clamping member 141 includes a clamping section 1411 and a connecting section 1412. The clamping section 1411 is used to lock with an external component. The connecting section 1412 has the clamping mating part formed on it. The clamping section 1411 is arc-shaped, and the connecting section 1412 is located in the middle part of the arc of the clamping section 1411.

[0055] In this embodiment, the clamping member 141 is divided into a clamping section 1411 (for engaging and locking with the pot body 20) and a connecting section 1412 (for connecting with the sliding member 142). The clamping section 1411 is designed with an arc-shaped structure. Since the pot body is generally a rotating component, the arc-shaped structure can increase the engagement length between the clamping section 1411 and the pot body 20, making the locking between the pot lid 10 and the pot body 20 more stable. The connecting section 1412 is located in the middle part of the clamping section 1411, which can make the clamping member 141 be subjected to force balance during movement, making the movement more stable.

[0056] It is conceivable that, in actual setup, in order to further improve the stability of the movement of the clamping member 141, when the arc length of the clamping segment 1411 is large, multiple connection points with the connecting segment 1412 can be set in the circumferential direction of the clamping member 141, so as to realize the multi-point connection between the clamping member 141 and the sliding member 142, thereby improving the connection strength and the stability of the clamping member 141 as it moves with the sliding member 142.

[0057] As one embodiment of this utility model, see the appendix. Figure 8 The clamping section 1411 includes a top plate 14111, a vertical plate 14112, and a bottom plate 14113. The top plate 14111, the vertical plate 14112, and the bottom plate 14113 are all constructed in an arc shape. The bottom plate 14113 is located at the bottom of the vertical plate 14112 and is spaced apart from the top plate 14111. The connecting section 1412 is located at the middle position of the arc of the top plate 14111. The vertical plate 14112 and the bottom plate 14113 have a discharge port 1426 corresponding to the connecting section 1412.

[0058] In this embodiment, the clamping section 1411 includes a top plate 14111, a vertical plate 14112, and a bottom plate 14113, and the cross-sections of the top plate 14111, the vertical plate 14112, and the bottom plate 14113 are formed as shown in the attached figure. Figure 8 The U-shaped structure shown can improve the structural strength of the clamping member 141 itself, thereby improving the locking strength between the lid 10 and the pot body 20.

[0059] In this embodiment, the clamping member 141 can be formed by bending a flat plate structure to form the structure of the clamping member 141 in this embodiment (arc and U-shaped cross-section structure). In this embodiment, the positions of the feeding port 1426 and the connecting section 1412 are designed to correspond. When feeding materials during production, when making blanks, the connecting section 1412 of two adjacent clamping members 141 corresponds to the feeding port 1426. This can make full use of raw materials and avoid material waste.

[0060] As one embodiment of this utility model, see the appendix. Figure 6 ,7 The sliding member 142 further includes a sliding support portion 1422 and a first docking portion 1423. The first docking portion 1423 and the second docking portion 1424 are respectively disposed at opposite ends of the sliding support portion 1422. The sliding support portion 1422 is used to slide and connect with an external component, and the first docking portion 1423 is used to connect with a drive component.

[0061] In this embodiment, the clamp assembly 14 is generally slidably arranged along the radial direction of the pot lid during use. The clamping member 141 is arranged on the outside of the sliding member 142. One end of the inner side of the clamping member 141 is used to connect with the driving component. The driving component is used to drive the overall sliding of the clamp assembly 14. Therefore, the inner side of the clamping member 141 is generally configured to cooperate with the output end of the driving component.

[0062] For example, the rack structure and connecting column structure shown in the attached figure are specifically described in the embodiment of the pot lid.

[0063] See appendix Figure 1-11 One embodiment of this utility model discloses a pot lid 10, which includes an inner lid 11 and an outer lid 12. The inner lid 11 and the outer lid 12 are stacked and connected, and an installation space is formed between the inner lid 11 and the outer lid 12. The pot lid 10 also includes a driving assembly 15 and a plurality of clamping assemblies 14 circumferentially distributed around the axis of the pot lid 10. At least one clamping assembly 14 includes a clamping member 141 and a sliding member 142. The sliding member 142 is located within the installation space and is slidably disposed on the inner lid 11 along the radial direction of the pot lid 10. The sliding member 142 has a second docking portion 1424, and the clamping member 141 has a clamping docking portion corresponding to the second docking portion 1424. The clamping docking portion and the second docking portion 1424 are engaged with each other so that the sliding member 142 and the clamping member 141 are detachably connected. The output end of the driving assembly 15 is connected to the sliding member 142 and is used to drive multiple clamping assemblies 14 to move synchronously in and out of the radial direction of the pot lid 10, and to enable the clamping member 141 to extend out of the installation space and lock with the outer wall of the pot body 20.

[0064] In this embodiment, the pot lid 10 includes a clamping assembly 14 and a driving assembly 15. In use, the operator can control the movement of the clamping assembly 14 by operating the driving assembly 15, so that when the pot lid 10 is placed on the pot body 20, the pot lid 10 and the pot body 20 can be locked or unlocked.

[0065] The clamp assembly 14 in this embodiment includes a sliding member 142 and a clamping member 141. The clamping member 141 and the sliding member 142 are detachably connected. The sliding member 142 is disposed in the installation space and can be installed on the inner cover 11 or the outer cover 12. The sliding member 142 provides a stable motion environment for the movement of the clamp assembly 14 in the radial direction. The clamping member 141 is fixedly connected to the sliding member 142 for locking with the pot body 20.

[0066] This embodiment does not specify how the clamping member 141 and the sliding member 142 are connected. In actual design, they can be connected by screws, or a structure that interlocks or plugs into each other can be designed to achieve a detachable connection.

[0067] In this embodiment, the clamp assembly 14 is configured as a split structure (clamping member 141 and sliding member 142). This allows for the rational design of the specific structure of clamping member 141 and sliding member 142 and the selection of appropriate materials for different parts (for example, clamping member 141 needs to be locked with pot body 20 and needs to ensure sufficient strength, so it can be made of metal; sliding member 142 needs to provide stable movement and has no strength requirements, so it can be made of a larger plastic structure). This makes the design more targeted and reduces production costs.

[0068] In one embodiment of this utility model, the clamping member 141 is made of metal, and the sliding member 142 is made of plastic. The metal clamping member 141 can ensure its own structural strength and locking strength with the pot body 20, while the plastic sliding member 142 can reduce production costs and the overall weight of the pot lid 10.

[0069] In this embodiment, the clamp assembly 14 is easy to assemble with the pot lid 10 during use, and it is also convenient to carry out targeted structural design for different functions of different parts. The clamping member 141 and the sliding member 142 in this application are connected by a snap-fit. Compared with the split structure of the clamp assembly 14 in the related technology, which adopts a bolt-connected structure, there is no need to set a separate connecting member, which reduces the number of parts of the pot lid 10 and makes assembly convenient.

[0070] As one embodiment of this utility model, see the appendix. Figure 8 The clamping member 141 includes a clamping section 1411 and a connecting section 1412. The clamping section 1411 is used to lock the pot body 20. The connecting section 1412 has the snap-fit ​​hole 14121. The clamping section 1411 is constructed in an arc shape around the axis of the pot lid 10. The connecting section 1412 is located in the middle part of the arc of the clamping section 1411. The surface of the connecting section 1412 is in contact with the surface of the docking body 14241.

[0071] As one embodiment of this utility model, see the appendix. Figure 8 The clamping section 1411 includes a top plate 14111, a vertical plate 14112, and a bottom plate 14113. The top plate 14111, the vertical plate 14112, and the bottom plate 14113 are all constructed in an arc shape around the axis of the pot lid 10. The top plate 14111 is disposed on the top side of the vertical plate 14112 and is fitted against the upper end face of the inner cover 11. The bottom plate 14113 is disposed at the bottom of the vertical plate 14112 and is spaced apart from the top plate 14111. The bottom plate 14113 is used to extend into the bottom side of the outer wall protrusion 21 of the pot body 20 to lock the pot body 20. The connecting section 1412 is disposed at the middle position of the top plate 14111 in the circumferential direction. The vertical plate 14112 and the bottom plate 14113 are formed with a discharge port 1426 corresponding to the connecting section 1412.

[0072] As one embodiment of this utility model, see the appendix. Figure 4 One of the inner cover 11 and the outer cover 12 is provided with a guide mechanism located in the installation space. The guide mechanism includes two baffles 122 that are arranged relatively apart. A radial sliding channel is formed between the two baffles 122. The sliding member 142 is slidably disposed between the two baffles 122, and the two sides of the sliding member 142 are respectively attached to the two baffles 122.

[0073] In this embodiment, the inner cover 11 or the outer cover 12 is provided with a guide mechanism for guiding the movement of the clamp assembly 14. In use, the sliding member 142 is disposed between two baffles 122. The two baffles 122 can limit the sliding member 142, so that the sliding member 142 can only move within the set space, thereby avoiding the slippage of the clamp assembly 14 during the movement and improving the stability of the movement.

[0074] It should be noted that the guide mechanism of the two spaced baffles 122 in this embodiment is only one embodiment of the present invention. In actual installation, it can also be set as other types of guide structures, such as groove and matching structure set in slider, guide rod structure through slider 142, etc., as long as it can achieve stable movement of clamp assembly 14.

[0075] As one embodiment of this utility model, see the appendix. Figure 4The drive assembly 15 includes an operation knob 151 and a drive gear 152. The operation knob 151 is rotatably disposed on the outer cover 12, and the top end of the operation knob 151 protrudes from the back of the outer cover 12. The drive gear 152 is fixedly connected to the operation knob 151 and is located between the two clamp assemblies 14. One end of the inner side of the sliding member 142 is formed with a rack 14231 that meshes with the drive gear 152. The racks 14231 on the two sliding members 142 are located on opposite sides of the drive gear 152.

[0076] The drive assembly 15 in this embodiment includes an operation knob 151 and a drive gear 152. The operation knob 151 is rotatably mounted on the outer cover 12. The part of the operation knob 151 protruding from the outer cover 12 is convenient for the operator to operate. The operation knob 151 and the drive gear 152 are fixedly connected. Specifically, in the design, the operation knob 151 and the drive gear 152 can be connected by screws or fixedly connected by a snap-fit ​​structure.

[0077] In this embodiment, the drive gear 152 is connected to the clamp assembly 14 within the installation space and enables transmission. The moving parts of the pot lid 10 are hidden, which can improve the overall appearance of the pot lid 10 and avoid the fear caused to the user during use. At the same time, it can avoid the influence of impurities on the moving parts.

[0078] In this embodiment, the operating knob 151 and the drive gear 152 transmit driving force through the meshing of the gear and rack 14231. Moreover, through the design of the rack 14231 position on the two sliding members 142 (set on opposite sides of the drive gear 152), the rotation of the drive gear 152 can drive the two clamp assemblies 14 to move synchronously in opposite directions or towards each other.

[0079] As one embodiment of this utility model, see the appendix. Figure 5 The drive assembly 15 includes an operation knob 151 and a drive disk 153. The operation knob 151 is rotatably disposed on the outer cover 12, and the top of the operation knob 151 protrudes from the back of the outer cover 12. The drive disk 153 is fixedly connected to the operation knob 151. Two circumferentially extending drive grooves 1531 are formed on the drive disk 153. The distance between each point on the drive groove 1531 and the axis of the drive disk 153 gradually changes circumferentially. A connecting post 1427 is formed on the inner side of the sliding member 142, and the connecting post 1427 extends into the drive groove 1531.

[0080] The drive assembly 15 in this embodiment includes an operation knob 151 and a drive disk 153. The operation knob 151 is set in the same way as described above. The movement of the clamp assembly 14 in this embodiment is driven by the drive disk 153. The drive disk 153 is provided with drive grooves 1531 corresponding to the number of clamp assemblies 14. The sliding member 142 is provided with a connecting post 1427 that cooperates with the drive grooves 1531. The connecting post 1427 and the drive grooves 1531 are inserted and rotated together. Thus, when the drive disk 153 rotates, the drive grooves 1531 can drive the clamp assembly 14 to reciprocate linearly.

[0081] As one embodiment of the present invention, the sliding member 142 is provided with a clearance hole 1421 for avoiding the valve body assembly 13.

[0082] Because pressure cookers need to maintain high pressure within the pot body 20 and ensure safety during use, the lid 10 of the pressure cooker is generally equipped with a valve assembly 13 for adjusting the pressure within the pot body 20. The valve assembly 13 generally includes an exhaust valve, a pressure valve, and a safety valve. Due to the limited volume of the lid 10, and the presence of numerous components, how to rationally distribute the positional relationships between the components and improve the compactness of the lid 10 structure is an important indicator for improving the quality of the lid 10. In this embodiment, the sliding member 142 is provided with a clearance hole 1421. During use, the valve assembly 13 passes through the clearance hole 1421, allowing the components to be centrally located and improving the structural compactness.

[0083] It should be noted that, in order to further ensure the safety of the pressure cooker during use, the valve body assembly 13 in this invention includes a safety valve assembly, which includes a valve body 131 and a valve core 132. In actual installation, this invention also sets the safety valve assembly and the clamp assembly 14 to a structure with a linkage effect to improve the safety of the pressure cooker during use.

[0084] See appendix Figure 1 , 23. A notch 1311 can be formed on the side wall of the valve body 131 of the safety valve of this utility model. The notch 1311 communicates with the valve hole 133 inside the valve body 131. The valve core 132 is slidably disposed in the valve hole 133 of the valve body 131. When the pot lid 10 is covered on the pot body 20, the pressure of the top of the valve core 132 in the pot body 20 is greater than the preset pressure and higher than the notch 1311. When the pressure of the top of the valve core 132 in the pot body 20 is less than the preset pressure and lower than the notch 1311, a thrust member 1425 is formed on the sliding member 142. The thrust member 1425 is positioned opposite to the notch 1311. The thrust member 1425 can extend into the valve hole 133 with the movement of the sliding member 142 when the top of the valve core 132 is lower than the notch 1311, and can be blocked by the valve core 132 when the top of the valve core 132 is higher than the notch 1311.

[0085] The working principle of the safety valve is that when the pressure valve or exhaust valve on the pot lid 10 fails, the pressure inside the pot body 20 increases to a certain value, and the valve core 132 of the safety valve will move up and down in the valve hole 133 to open the valve hole 133 of the safety valve, thereby venting the gas inside the pot body 20.

[0086] When the pressure inside the pot body 20 is low, the valve core 132 of the safety valve is in a low position (the top of the valve core 132 is below the notch 1311). At this time, the thrust member 1425 can enter the valve hole 133 through the notch 1311, and the valve core 132 will not block the thrust member 1425. At this time, the clamp assembly 14 can slide with the operator's operation to lock or unlock. When the pressure inside the pot body 20 is too high, under the action of air pressure, the valve core 132 of the safety valve will be pushed up to the high position. (Valve core 132 is opposite to notch 1311). Due to the blocking effect of valve core 132 of safety valve, thrust member 1425 cannot enter valve hole 133 from notch 1311, which is equivalent to limiting the range of motion of clamp assembly 14. This prevents clamp assembly 14 from being released from locking with pot body 20, so that when the pressure cooker is in use, the pressure inside pot body 20 is too high and the lid 10 cannot be opened. This makes clamp assembly 14 and safety valve assembly work together to ensure the safety of pressure cooker use.

[0087] The second aspect of this utility model discloses a pressure cooker, see appendix. Figure 12 , 13 The container includes a pot body 20 and a pot lid 10. The pot lid 10 adopts a first aspect of the pot lid 10. A circumferential outer wall protrusion 21 is formed on the outer wall of the open end of the pot body 20. When the pot lid 10 is placed on the pot body 20, the driving assembly 15 can drive the clamping assembly 14 to move radially inward and outward along the pot lid 10, and can make the clamping member 141 extend to the bottom side of the outer wall protrusion 21.

[0088] In this embodiment, the lid 10 and the pot body 20 are locked together by the clamp assembly 14 and the outer wall boss 21 on the pot body 20. The bottom plate 14113 of the clamping member 141 of the clamp assembly 14 can extend from the outside of the pot body 20 into the bottom side of the outer wall boss 21 to form a snap-fit ​​with the outer wall boss 21. The outer wall boss 21 is set to be circumferential, so that the outer wall boss 21 and the clamp assembly 14 can be engaged at any position on the pot body 20 when the lid 10 is placed on it, without any limitation on the position of the lid, making it more convenient to use.

[0089] Of course, it is conceivable that a handle 22 could also be installed on the outer wall of the pot body 20, as shown in the attached figure. Figure 12 , 13 As shown, this makes the pressure cooker easy to move.

[0090] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
