Description

Technical Field

[0001] The utility model relates to the technical field of pressure cookers, and particularly relates to a lid assembly and a floating pressure cooker. Background Art

[0002] When in use, a pressure cooker generally includes an exhaust valve as the main air release path. During use, the high-pressure gas in the pot is discharged through the exhaust valve. In some cases, the exhaust valve may fail and cannot exhaust air, which will cause the pressure in the pot to rise sharply and pose a safety risk.

[0003] In the prior art, an exhaust device is provided between the lid and the pot body as a secondary pressure relief path. When the exhaust valve does not work properly, the air pressure can push the lid open for exhaust and pressure relief. When the pressure relief device in the related technology is performing pressure relief, problems such as uneven force on the lid during the upward floating of the lid may cause the lid to be stuck and unable to float upward, resulting in slow and uneven pressure relief efficiency during pressure relief, and there is also a safety risk. Summary of the Utility Model

[0004] The utility model aims to solve one of the technical problems in the related technology to a certain extent. For this purpose, the utility model provides a lid assembly and a floating pressure cooker, which can make the upward floating of the lid smoother and ensure sufficient upward floating space, so that the exhaust is smoother.

[0005] To achieve the above object, the first aspect of the utility model discloses a lid assembly. The lid assembly includes a lid body and a pressure relief bracket. The pressure relief bracket is arranged on the back of the lid body. The pressure relief bracket includes a connecting portion and a deformation unit extending towards the two side edges of the lid body. The connecting portion and the lid body are mutually attached and fixedly connected through at least one connecting member. The end of the deformation unit away from the connecting portion forms a pressure-bearing portion, and the pressure-bearing portion is used to be pressed against the pot body through a locking member; the deformation unit can elastically deform under the action of a set external force, so as to generate a gap between the lid assembly and the pot body.

[0006] In this technical solution, a pressure relief bracket integrated with the pot lid is provided. During the cooking process of the pressure cooker, when the pressure in the pot body is too high, the pot lid can float upward and form a gap with the pot body, and the gas in the pot body can escape from this gap to achieve pressure relief, improving the safety during the use of the pressure cooker. In addition, there is a gap between the deformation unit and the pot lid body, and this gap can accommodate the deformation of the pot lid body itself and the deformation generated by the deformation unit, avoiding the interference between the pot lid and the pressure relief bracket caused by the irregular deformation of the pot lid and the deformation unit when the pot lid floats, resulting in problems such as the pot lid being unable to float or having difficulty floating to the predetermined gap, enabling the pot lid to float smoothly and ensuring the gap between the floating pot lid and the pot body, improving the pressure relief effect.

[0007] Further, the gap is not less than the maximum allowable floating amount of the pot lid body, and the maximum allowable floating amount of the pot lid body is 3 - 5 mm.

[0008] Further, the deformation unit includes a deformed section arranged obliquely and a flat section connected to the end of the deformed section. The flat section forms the pressure-bearing part. There is a gap between the deformation unit and the pot lid body, and the gap gradually increases from the connecting part to the pressure-bearing part. The middle part of the pressure relief bracket forms the connecting part, and the connecting part is in planar contact with the pot lid body. The connecting part and the pot lid body are connected by a connecting piece passing through the central positions of the connecting part and the pot lid body. The pressure-bearing part is more convenient to be fixed, improving the fixing effect; the obliquely arranged deformed section and the pot lid body can improve the overall strength and also reduce the overall volume of the pot lid.

[0009] Further, both ends of the pressure relief bracket extend towards the edges on both sides of the pot lid body and form two symmetrically distributed deformation units. During use, the pot lid assembly can float up and down as a whole, making the gap between the circumferential direction of the pot lid assembly and the pot body uniform, improving the stability of pressure relief and the pressure relief efficiency.

[0010] In the second aspect of the present utility model, a floating pressure cooker is disclosed. The pressure cooker includes a pot body and the pot cover assembly of the first aspect. The pressure cooker further includes a locking mechanism for locking the pot cover assembly and the pot body. The locking mechanism includes a first locking member disposed on the pot body and a second locking member disposed on the pot cover assembly. The locking mechanism can fix the pressure-bearing part. The pot cover assembly further includes a control member for switching the second locking member between a locking position and an unlocking position. In the locking position, the first locking member and the second locking member are locked with each other so that the pot cover assembly can be fixed to the pot body. In the unlocking position, the first locking member and the second locking member are disengaged from each other so that the pot cover assembly can be detached from the pot. Through the locking mechanism, a stable connection between the pot cover assembly and the pot body can be achieved, and the fixing of the pressure-bearing part can also be realized. In this way, when the air release bracket deforms, the detachment of the air release bracket from the pot body can be avoided, thereby improving the safety of using the pressure cooker.

[0011] Further, the first locking member includes a flange extending outward from the open end of the pot body, and the second locking member includes a movable hook. The movable hook includes a hook body movably mounted on the air release bracket and a hook provided on the hook body. The hook extends toward the edge of the pot cover body. In the locking position, the hook can hook the lower end of the flange from the outside of the pot body so that the pot cover assembly is locked on the pot body, and the end of the deformation unit away from the connecting part is clamped and fixed by the hook body and the flange.

[0012] Further, the first locking member includes a through hole provided on the side wall of the pot body, and the second locking member includes a movable insertion plate. The movable insertion plate includes an insertion plate body movably mounted on the air release bracket and an insertion end provided at one end of the insertion plate body. The insertion end extends toward the edge of the pot cover body. In the locking position, the insertion end can be inserted into the through hole from the inside of the pot body so that the pot cover assembly is locked on the pot body, and the pressure-bearing part is clamped and fixed by the movable insertion plate and the through hole. Locking the pot cover assembly and the pot body from the inside of the pot body reduces the risk of the pressure-bearing part detaching from the pot body when the deformation unit of the air release bracket deforms, improving the safety risk.

[0013] Further, a first mounting portion for slidably mounting the second locking member is provided on the side of the air release bracket facing away from the pot body. The air release bracket includes baffles protruding from both side edges of the air release bracket. The two baffles are located on both sides of the first mounting portion. The protruding ends of the baffles are formed with bent portions folded toward the first mounting portion. The main body of the second locking member is slidably mounted on the first mounting portion. Improve the stability of the installation and movement of the second locking member.

[0014] Further, the control component includes a first turntable and a knob fixedly connected to the first turntable. A second mounting portion for mounting the first turntable is formed on the connecting portion of the air release bracket. The first turntable is rotatably mounted on the second mounting portion. A driving groove is formed on the first turntable. One end of the second locking member is provided with a protrusion inserted into the driving groove. The driving groove includes a locking section for making the second locking member in the locking position and an unlocking section for making the second locking member in the unlocking position. The locking section and the unlocking section are smoothly transitioned. The rotation of the first turntable can make the protrusion slide between the locking section and the unlocking section, so that the second locking member can be switched between the locking position and the unlocking position. Setting the locking position and the unlocking position to cover a certain width area can make the operation more convenient and improve the locking stability.

[0015] Further, the pot lid assembly further includes a stop valve provided on the pot lid body. The stop valve is placed below the first turntable. A stop valve hole is formed on the first turntable. The stop valve hole is set as an arc structure around the center of the first turntable. The first valve hole end of the stop valve hole corresponds to the locking section. The second valve hole end of the stop valve hole corresponds to the position between the locking section and the unlocking section. When the valve core of the stop valve is placed at the first valve hole end, the second locking member is placed at the end position of the locking section. When the valve core of the stop valve is placed at the second valve hole end, the second locking member is placed at the middle of the locking section. When the pressure in the pot body is too high, the movement of the second locking member towards the unlocking position is restricted, avoiding the safety risks that may occur when opening the pot lid under high pressure.

[0016] Further, the pot lid assembly is also provided with an exhaust valve. The exhaust valve includes a movably mounted exhaust valve core and a pushing member connected to one side of the exhaust valve core. A groove opposite to the end of the pushing member is provided on the first turntable. The side wall of the groove is provided with an inclined surface. When the second locking member is in the locking section, the rotation of the first turntable can push the pushing member through the inclined surface to drive the movement of the exhaust valve core. Combining the actions of the exhaust valve and the first turntable makes the connection between the components closer and makes the overall structure more compact.

[0017] Further, the control component includes a button and a movable plate assembly. The movable plate assembly is slidably mounted on the back of the air release bracket. The movable plate assembly includes a movable plate and an inclined tooth block corresponding to the movable plate. The first end of the movable plate is connected to the second locking member, and the second end of the movable plate is connected to the inclined tooth block by a first return spring. The inclined tooth block is provided with a passive inclined surface, and the button is disposed on the upper part of the inclined tooth block and is provided with an active inclined surface corresponding to the passive inclined surface. Pressing the button can push the second locking member to slide through the mutual extrusion of the active inclined surface and the passive inclined surface, and the first return spring can reset the second locking member.

[0018] Further, the control component includes a pinching assembly and a second turntable. The second turntable is fixed on the air release bracket. A driving groove is formed on the second turntable. The second locking member includes a protrusion inserted into the driving groove. The rotation of the second turntable drives the second locking member to slide along the air release bracket. The pinching assembly includes two pinching blocks symmetrically distributed on both sides of the center of the second turntable. The second turntable is provided with two long grooves corresponding to the pinching blocks respectively. The pinching block includes a connecting column inserted into the long groove. Squeezing the two pinching blocks can drive the second turntable to rotate through the cooperation of the connecting column and the long groove. Two second return springs symmetrically distributed on both sides of the center of the second turntable are connected between the two opposite pinching blocks. The second return spring is used to reset the second turntable and the pinching block when the pinching block loses external driving force.

[0019] Further, the pot lid assembly further includes a panel. The panel covers the pot lid body and can cover the first turntable, the air release bracket and the second locking member. The knob and the exhaust valve have parts protruding from the panel.

[0020] Further, a concave connecting portion is formed in the middle of the air release bracket. The two ends of the air release bracket extend towards both sides of the pot lid body respectively to form the bearing portions. The bottom surface of the connecting portion is attached to and fixedly connected to the top surface of the pot lid body. The two bearing portions can be fixed synchronously relative to the pot body. This improves the strength of the air release bracket, enables the pot lid assembly to float stably as a whole when floating, and can evenly release air in the circumferential direction of the pot lid body after floating, improving the air release efficiency.

[0021] Further, the pot body includes a first straight cylinder, a conical cylinder, a second straight cylinder and a bottom plate connected in sequence. One end of the first straight cylinder forms the opening of the cooking cavity of the pot body. An annular seal is provided at the edge of the pot lid body; the inner side wall of the conical cylinder can be in sealing cooperation with the seal. Through the design of the conical cylinder, the bonding property with the seal can be improved, and the sealing effect can be improved.

[0052] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Based on the embodiments in the implementation mode, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0053] As used in this specification, the phrase "in one embodiment" or "example" or "instance" means that the specific features, structures, or characteristics described in connection with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" at various positions in the specification does not necessarily refer to the same embodiment.

[0054] See the attached Figure 1 、 2 Referring to the attached drawings, one embodiment of the present utility model discloses a pot lid assembly 20. The pot lid assembly 20 includes a pot lid body 21 and a pressure relief bracket 22. The pressure relief bracket 22 is disposed on the back of the pot lid body 21 (the side facing away from the pot body 10 when the pot lid body 21 cooperates with the pot body 10). The pressure relief bracket 22 includes a connecting portion 221 connected to the pot lid body 21 and a deformation unit 222 extending toward the edges on both sides of the pot lid body 21. The end of the deformation unit 222 away from the connecting portion 221 forms a pressure-bearing portion 223. The pressure-bearing portion 223 is used to be fixed relative to the pot body 10 when the pot lid assembly 20 is buckled on the pot body 10. The connecting portion 221 and the pot body 10 are mutually attached and fixedly connected through at least one connecting member 26. The deformation unit 222 can elastically deform under the action of a set external force, so as to generate a gap between the pot lid assembly 20 and the pot body 10.

[0055] When the pot lid assembly 20 in this embodiment is buckled on the pot body 10, when the air pressure in the pot body 10 is greater than the set pressure, the pot lid body 21 will float in the direction away from the pot body 10, and drive the deformation unit 222 to generate elastic deformation, thereby generating a gap between the pot lid body 21 and the side wall of the pot body 10.

[0056] In this embodiment, the pressure relief bracket 22 of the pressure cooker is used as a second-stage pressure relief device. During use, an exhaust valve 62 for exhausting gas is further provided on the pot lid assembly 20. The exhaust valve 62 is used as a first-stage pressure relief device. During use, when the air pressure in the pot body 10 is between 60 - 80 KPa, the exhaust valve 62 is used for exhausting gas; when the air pressure in the pot body 10 increases to 90 - 110 KPa, at this time, the pot lid assembly 20 can be used for pressure relief by floating.

[0057] The working principle of the floating pressure cooker in this embodiment during use is as follows: When cooking is required, first cover the lid assembly 20 on the pot body 10. A sealed area will be formed between the lid bodies 21 to achieve high-pressure cooking of the food in the pot body 10. When the pressure in the pot body 10 increases to a certain value (>90 KPa), the lifting force of the lid body 21 caused by the air pressure in the pot body 10 is greater than the tensile force generated by the deformation of the air release bracket 22. At this time, the lid body 21 will move upward. Since the connecting part 221 between the lid body 21 and the air release bracket 22 is fixedly connected, it will drive the connecting part 221 of the air release bracket 22 to move upward. And the pressure-bearing part 223 of the air release bracket 22 is relatively fixed to the pot body 10. In order to adapt to the upward floating of the pot body 10 and the connecting part 221, the deformation unit 222 of the air release bracket 22 will produce elastic deformation. It can be seen that during the upward floating process, the lid assembly 20 is always connected to the pot body 10, avoiding the safety risk of the lid bursting due to excessive pressure.

[0058] In this embodiment, by providing an air release bracket 22 integrated with the lid, during the cooking process of the pressure cooker, when the pressure in the pot body 10 is too high, the lid can float upward and form a gap with the pot body 10, and the gas in the pot body 10 can escape from this gap to achieve pressure relief, improving the safety during the use of the pressure cooker.

[0059] It should be noted that since when the pressure in the pot body 10 is too high, the air pressure in the pot body 10 will first act on the lid body 21. In actual use, the lid body 21 may also produce a certain amount of deformation under the action of the air pressure in the pot body 10. At the same time, the deformation unit 222 of the air release bracket 22 will produce a large deformation (it should be noted that the whole of the air release bracket 22 in the present utility model can be set to be made of elastic material, but since in actual design, the connecting part 221 and the pressure-bearing part 223 of the air release bracket 22 will be fixed, so in actual use, the main part that actually plays the deformation effect is the deformation unit 222. Of course, based on this, in actual setting, only the deformation unit 222 of the air release bracket 22 can be set to be made of elastic material). In addition, when the air release bracket 22 of the present utility model is actually set, a metal sheet structure with elasticity can be adopted.

[0060] Since during the upward floating process of the lid assembly 20 of the pressure cooker, the irregular deformation of the lid and the deformation unit 222 may cause the upper end surface of the lid body 21 to abut against the deformation unit 222. At this time, the deformation unit 222 will block the upward movement of the lid body 21, making it difficult for the lid body 21 to float upward and unable to obtain an ideal dimensional gap between the lid body 21 and the pot body 10, which will further cause the problem of slow discharge speed of the high-pressure gas in the pot body 10 and easily lead to safety risks.

[0061] Between the connecting part 221 of the air leakage bracket 22 of the present utility model and the pot lid body 21, there are respectively provided parts that are flatly attached. In this way, during installation, the stability of the installation of the air leakage bracket 22 can be ensured, and at the same time, the strength of the pot lid body 21 can be enhanced, and the installation is convenient. When specifically connecting, the two are fixed through the connecting piece 26. Of course, in actual setting, the attached parts of the two can also adopt the form of arc surface attachment, or can be set as multiple concave and convex planes attached to each other, which can further improve the overall strength and the stability of installation.

[0062] The present utility model is provided with a spacing 25 between the deformation unit 222 and the pot lid body 21, see the appendix Figure 1 、 8 , this spacing 25 can accommodate the deformation of the pot lid body 21 itself and the deformation generated by the deformation unit 222, avoiding the contact interference between the pot lid and the deformation unit 222 caused by the irregular deformation of the pot lid when the pot lid floats upward, resulting in the problem that the pot lid cannot float upward or the pot lid floats upward with difficulty and cannot reach the predetermined gap, so that the pot lid can float smoothly and can ensure the gap between the floating pot lid and the pot body 10, improving the air leakage effect.

[0063] In actual setting, the size of this spacing 25 can also be designed to be not less than the floating amount of the pot lid body 21. The floating amount of the pot lid body 21 in the present utility model during use is ~mm. Since the seal 23 has a certain elasticity, if the floating amount of the pot lid body 21 is too small, it may still be within the sealing range of the seal 23 at this time. If the floating amount of the pot lid body 21 is too large, it is easy to generate safety risks and is also easy to cause plastic deformation of the air leakage bracket 22. Therefore, when designing and setting, the spacing 25 between the deformation unit 222 and the pot lid body 21 should also take into account the sealing deformation amount of the seal 23 and the elastic deformation amount of the air leakage bracket 22. Generally, the spacing 25 is set to be greater than the sealing deformation amount of the seal 23 but not greater than the maximum elastic deformation amount of the air leakage bracket 22.

[0064] In addition, it should be noted that when setting this spacing 25, since the space between the pot lid body 21 and the air leakage bracket 22 has a certain width in the radial direction, then this spacing 25 can be designed to be evenly distributed throughout the width, and of course, it can also be set to be non-uniformly distributed. In one embodiment of the present utility model, the deformation unit 222 includes a deformed section arranged obliquely and a flat section connected to the end of the deformed section, and the flat section forms the pressure-bearing part 223, and a smooth transition is provided between the flat section and the deformed section.

[0065] The spacing 25 gradually increases from the connecting portion 221 to the pressure-bearing portion 223. The pressure-bearing portion 223 in this embodiment is arranged as a planar structure, making it more convenient to be fixed and improving the stability of fixation; the inclined deformation section and the pot lid body 21 can, on the one hand, improve the overall strength, and on the other hand, reduce the overall volume of the pot lid. The spacing 25 gradually increases from the connecting portion 221 to the pressure-bearing portion 223. Since during the actual use of the pressure cooker, during the floating process, the amount of deformation generated by each part of the deformation unit 222 is different. By reasonably designing the spacing 25 between each part and the pot lid body 21, it can also ensure that the deformation unit 222 does not contact the pot body 10 during the floating process, which can further save space and reduce the volume of the pot lid assembly 20.

[0066] Among them, the connecting portion 221 in this embodiment is arranged as a planar structure (mutually fitting and connecting with the planar part on the pot lid body 21 to achieve a more stable connection effect), and a connecting hole is provided on the connecting portion 221 for passing through the connecting piece 26 to realize the connection between the air release bracket 22 and the pot lid body 21.

[0067] The pressure-bearing portion 223 of the air release bracket 22 in the present utility model can be directly fixed on the pot body 10. In this way, during use, the versatility of the pot lid assembly 20 can be improved, making the pot lid assembly 20 applicable to any pressure cooker body 10 with the same caliber.

[0068] Both ends of the air release bracket 22 of the present utility model extend towards the edges on both sides of the pot lid body 21 and form two symmetrically distributed deformation units 222. During use, the pot lid assembly 20 can float up and down as a whole (not deflect to one side), making the gap between the circumferential direction of the pot lid assembly 20 and the pot body 10 uniform, improving the stability of air release and the air release efficiency.

[0069] The second aspect of the present utility model discloses a floating pressure cooker, including a pot body 10 and the pot lid assembly 20 of the first aspect. The pressure cooker further includes a locking mechanism for locking the pot lid assembly 20 and the pot body 10. The locking mechanism includes a first locking member provided on the pot body 10 and a second locking member provided on the pot lid assembly 20. The locking mechanism can fix the pressure-bearing portion 223; the pot lid assembly 20 further includes a control component for switching the second locking member between the locking position and the unlocking position; in the locking position, the pot lid assembly 20 can be locked on the pot body 10 through the locking mechanism; in the unlocking position, the pot lid assembly 20 can be disengaged from the pot body 10.

[0070] The locking mechanism of the present invention can not only realize the locking of the pot cover assembly 20 and the pot body 10, but also fix the pressure-bearing portion 223 of the air-release bracket 22 on the pot body 10. In this way, when the pressure in the pot body 10 is too high, the pressure-bearing portion 223 of the air-release bracket 22 is equivalent to providing a deformation fixing point for the air-release bracket 22, thereby preventing the air-release bracket 22 from being separated from the pot body 10 due to the elastic deformation tension caused by the air pressure rise, thereby improving the safety of the pressure cooker.

[0071] The locking mechanism of the present invention has various forms. The present invention provides the following embodiments: 1. See the attached Figure 1 , 4 , 6, 7, the first locking member of one embodiment of the locking mechanism of the utility model includes a flange 31 extending outward from the open end of the pot body 10, and the second locking member includes a movable hook 32, the movable hook 32 includes a hook body 321 movably mounted on the air release bracket 22 and a hook 322 arranged on the hook body 321, and the hook 322 extends toward the edge of the pot cover body 21; in the locked position, the hook 322 can be hooked on the lower end of the flange 31 from the outside of the pot body 10 to lock the pot cover assembly 20 on the pot body 10, and the pressure-bearing portion 223 of the deformation unit 222 is clamped and fixed by the hook body 321 and the flange 31.

[0072] The first locking member in this embodiment adopts the flange 31 structure formed by the pot body 10 itself, and there is no need to add other accessories or structures to the pot body 10. The second locking member on the pot cover assembly 20 is set to a structure of a movable hook 32 adapted to the flange 31. The movable hook 32 in this embodiment is installed on the top surface of the air-release bracket 22. Of course, in actual settings, the first locking member can also be installed on other components (for example, an intermediate component for installing the first locking member is added to the air-release bracket 22). The first locking member is a movable member, and the unlocking position and the locking position are realized through the activity of the first locking member. It should be noted that the structure of the movable hook 32 and the flange 31 in the present embodiment is fixed to the pot body 10 from the outside of the pot body 10, and the pressure-bearing portion 223 of the air-release bracket 22 is clamped and fixed by the hook body 321 and the flange 31. When the pressure cooker floats and the air-release bracket 22 is stretched, since the air-release bracket 22 and the movable hook 32 are connected as a whole, the greater the elastic deformation of the air-release bracket 22, the greater the force applied to the main body of the movable hook 32 in the vertical direction. In this way, the clamping effect of the movable hook 32 on the air-release bracket 22 is more stable, further improving the safety.

[0073] In addition, it should be noted that when the movable hook 32 and the flanging 31 are hooked and fixed, when the lid assembly 20 floats upward, deformation will occur at the locking position, causing the contact surface to change from a surface to a point, which will result in the risk of unhooking. In actual setting of this embodiment, the hook 322 of the movable hook 32 can be set to a structure with a certain width as shown in the attached Figure 5 , 6 . In this way, when floating, the contact surface will become a line contact, increasing the contact area and reducing the risk of unhooking. Of course, the hook 322 can be further set to an arc structure that conforms to the flanging 31 of the pot body 10, which can further enhance the connection effect.

[0074] II. Refer to the attached Figure 8 . In one embodiment of the locking mechanism of the present utility model, the first locking member includes a through hole 41 provided on the side wall of the pot body 10, and the second locking member includes a movable insertion plate 42. The movable insertion plate 42 includes an insertion plate main body 421 movably installed on the air release bracket 22 and an insertion end 422 provided at one end of the insertion plate main body 421. The insertion end 422 extends towards the edge of the lid body 21; in the locked position, the insertion end 422 can be inserted into the through hole 41 from the inside of the pot body 10 to lock the lid assembly 20 on the pot body 10, and the pressure-bearing part 223 is clamped and fixed by the movable insertion plate 42 and the through hole 41.

[0075] In this embodiment, the first locking member is set as the through hole 41 opened on the side wall of the pot body 10. Similarly, no additional accessories need to be added to the pot body 10. The position of the through hole 41 is generally located between the end of the open end of the pot body 10 and the sealing area between the lid assembly 20 and the pot body 10. The second locking member on the lid assembly 20 is set as a structure of a movable insertion plate 42 adapted to the through hole 41. Similarly, the movable insertion plate 42 in this embodiment is set as a structure directly connected to the air release bracket 22. During use, the movement of the movable insertion plate 42 enables it to be inserted into or disengaged from the through hole 41, thereby realizing the switching between the locked position and the unlocked position. Similarly, during the stretching process of the air release bracket 22 when the pressure cooker floats, since the air release bracket 22 and the movable insertion plate 42 are connected as a whole, the greater the elastic deformation of the air release bracket 22, the greater the force applied to the movable insertion plate 42 in the vertical direction, which makes the clamping effect of the movable insertion plate 42 on the air release bracket 22 more stable, further improving the safety. In addition, in this embodiment, the lid assembly 20 and the pot body 10 are locked from the inside of the pot body 10. When the deformation unit 222 of the air release bracket 22 deforms, the pressure-bearing part 223 of the air release bracket 22 is less likely to disengage from the pot body 10, further improving the safety effect.

[0076] Refer to the attached Figure 8 , 9, 10, 11, in order to better adapt to the connection between the through hole 41 and the movable plug 42 in this embodiment, a positioning hole is provided on the handle 64 of the pot body 10, and a positioning block corresponding to the positioning hole is provided at the edge of the pot cover assembly 20. When the pot cover assembly 20 is buckled on the pot body 10, the positioning block is inserted into the positioning hole to realize the relative fixation of the positions of the pot cover assembly 20 and the pot body 10. At this time, the positions of the movable plug 42 and the through hole 41 on the pot body 10 correspond to each other, avoiding the problem that the movable plug 42 cannot be inserted into the through hole 41 due to installation errors.

[0077] Since the second locking member of the present utility model is a movable member, the installation stability and firmness thereof are directly related to the locking effect of the pot cover assembly 20 and the pot body 10. In order to improve the installation stability of the second locking member, a first installation portion for slidably installing the second locking member is provided on the side of the air release bracket 22 facing away from the pot body 10. The air release bracket 22 includes baffles 224 protruding from both side edges of the air release bracket 22. The two baffles 224 are located on both sides of the first installation portion. A bent portion 225 that folds toward the first installation portion is formed at the protruding end of the baffle 224. The main body of the second locking member is slidably installed in the first installation portion. During installation, the positions of the two sides of the second locking member are defined by the baffles 224 on both sides, the bottom of the second locking member is defined by the top surface of the air release bracket 22, and the top is defined by the bent portion 225, thereby realizing a stable installation effect of the second locking member and improving the installation and movement stability of the second locking member.

[0078] It should be noted that, during actual use, the bent portion 225 or the baffle 224 provided on the air release bracket 22 can not only improve the installation stability of the second locking member, but also improve the structural strength of the air release bracket 22 itself (at this time, the baffle 224 and the bent portion 225 are equivalent to the structure of a reinforcing rib).

[0079] It should be noted that the number of the second locking members in the present utility model is set to two, and the two second locking members are symmetrically distributed. Refer to the attached Figure 4 、 5 、8. A concave connecting portion 221 can be formed in the middle of the air release bracket 22. The two ends of the air release bracket 22 extend toward both sides of the pot cover body 21 to form the bearing portions 223. The bottom surface of the connecting portion 221 is in close contact with and fixedly connected to the top surface of the pot cover body 21. The two bearing portions 223 can be fixed synchronously relative to the pot body 10. The strength of the air release bracket 22 is improved, and the pot cover assembly 20 can float stably as a whole when floating, and can uniformly release air in the circumferential direction of the pot cover body 21 after floating, improving the air release efficiency.

[0080] The movement of the second locking member of the present utility model is realized through a control member. In actual settings, the control member has various forms. The following are several examples of commonly used control members:

[0081] 1. Refer to Attachments Figure 1 、 4 、 6, and 7. The control member includes a first turntable 51 and a knob 512 fixedly connected to the first turntable 51. A second mounting portion for mounting the first turntable 51 is formed on the connecting portion 221 of the air release bracket 22. The first turntable 51 is rotatably mounted on the second mounting portion. A driving groove 511 is formed on the first turntable 51. One end of the second locking member is provided with a protrusion 513 inserted into the driving groove 511. The driving groove 511 includes a locking section 511a for making the second locking member in the locked position and an unlocking section 511b for making the second locking member in the unlocked position. The locking section 511a and the unlocking section 511b are smoothly transitioned. The rotation of the first turntable 51 can make the protrusion 513 slide between the locking section 511a and the unlocking section 511b, so that the second locking member can be switched between the locked position and the unlocked position.

[0082] In the use of the control member in this embodiment, when the user rotates the knob 512 (the knob 512 protrudes from the pot lid assembly 20, refer to Attachments Figure 2 、 9 ), the knob 512 will drive the first turntable 51 to rotate. The rotation of the first turntable 51 drives the reciprocating movement of the second locking member through the cooperation of the driving groove 511 and the protrusion 513. By setting the shape of the driving groove 511, the movement range of the second locking member can be well controlled. In the present utility model, by setting the shape of the driving groove 511, the locked position and the unlocked position are set to cover a certain width area. In this way, when the second locking member and the first locking member on the pot body 10 are locked, unlocking will not be caused by the slight shaking of the second locking member, and the locking stability can be improved.

[0083] 2. Refer to Attachments Figure 12a 、 12b, the control component includes a button 52 and a movable plate assembly. The movable plate assembly is slidably mounted on the back of the air release bracket 22. The movable plate assembly includes a movable plate and an inclined tooth block corresponding to the movable plate. The first end of the movable plate is connected to the second locking member, and the second end of the movable plate is connected to the inclined tooth block through a first return spring 523. The inclined tooth block is provided with a passive inclined surface 515, and the button 52 is arranged on the upper part of the inclined tooth block and is provided with an active inclined surface 515 corresponding to the passive inclined surface 515. Pressing the button 52 can push the second locking member to slide through the mutual extrusion of the active inclined surface 515 and the passive inclined surface 515, and the first return spring 523 can reset the second locking member.

[0084] This embodiment is applicable to the synchronous movement of two symmetrically distributed second locking members. The control component includes a button 52, and the movable plate assembly includes a first movable plate 521 and a second movable plate 522. When setting, the first movable plate 521 and the second movable plate 522 are respectively connected to two symmetrically distributed second locking members. Among them, a first inclined tooth block with a first inclined surface 515 and a second inclined tooth block with a second inclined surface 515 are arranged at the bottom of the button 52; the first movable plate 521 is provided with a third inclined tooth block with a third inclined surface 515, and the second movable plate 522 is provided with a fourth inclined tooth block with a fourth inclined surface 515. Among them, the first inclined tooth block and the third inclined tooth block are arranged oppositely, and the second inclined tooth block and the fourth inclined tooth block are arranged oppositely; when pressing the button 52 downward, the first inclined surface 515 abuts and cooperates with the third inclined surface 515 so that the button 52 can drive the first movable plate 521, and the second inclined surface 515 abuts and cooperates with the fourth inclined surface 515 so that the button 52 can drive the second movable plate 522, so that the synchronous telescopic movement of two symmetrically distributed second locking members can be realized. Among them, a first return spring 523 can be arranged between the first movable plate 521 and the second movable plate 522 to facilitate the reset of the second locking member.

[0085] III. Refer to the appendix Figure 13 , 14, 15, 16, the control component includes a pinching assembly and a second turntable 531. The second turntable 531 is fixed on the air release bracket 22. A driving groove 511 is formed on the second turntable 531. The second locking member includes a protrusion 513 with one end inserted into the driving groove 511. The rotation of the second turntable 531 drives the second locking member to slide along the air release bracket 22. The pinching assembly includes two pinching blocks 53 symmetrically distributed on both sides of the center of the second turntable 531. Two elongated slots 533 corresponding to the pinching blocks 53 are provided on the second turntable 531. The pinching block 53 includes a connecting column 534 inserted into the elongated slot 533. Squeezing the two pinching blocks 53 can drive the second turntable 531 to rotate through the cooperation of the connecting column 534 and the elongated slot 533. Two second return springs 532 symmetrically distributed on both sides of the center of the second turntable 531 are connected between the two opposite pinching blocks 53. The second return spring 532 is used to reset the second turntable 531 and the pinching block 53 when the pinching block 53 loses external driving force.

[0086] The control component in this embodiment is configured with two pinching blocks 53 and a second turntable 531. Both pinching blocks 53 are connected to the second turntable 531. The two pinching blocks 53 approach or move away from each other to rotate the first turntable 51.

[0087] In this embodiment, when the user squeezes the two pinching blocks 53 towards the middle, the two pinching blocks 53 will apply a rotational torque to the second turntable 531 (through the interaction of the elongated slot 533 and the connecting column 534), causing the second turntable 531 to rotate counterclockwise or clockwise. This rotational movement will drive other components connected to the second turntable 531 (the first locking member is connected to the driving groove 511 of the second turntable 531 through the protrusion 513) to perform corresponding movements, so as to realize the switching of the first locking member between the unlocking position and the locking position. A second return spring 532 can also be arranged between the two pinching blocks 53. When the user operates the pinching block 53 to drive the second turntable 531 to rotate, the second return spring 532 will be compressed or stretched. Once the user releases the pinching block 53, the second return spring 532 will quickly return to its original shape, thereby driving the pinching block 53 back to the initial position. The control component in this embodiment is applicable to the structure where the first locking member is the flanging 31 and the second locking member is the movable hook 32 in the present invention.

[0088] Of course, there are many other forms of the control component that can drive the first locking member to slide reciprocally. See the appendix Figure 17, for example, through the structure of a rotatable rotary handle 54 cooperating with a turntable 51. The rotary handle 54 and the turntable are connected by a pushing block. The forward rotation of the rotary handle 54 drives the rotation of the turntable 51 through the pushing block. Further, the rotation of the turntable 51 drives the second locking member to slide towards the locking position. The reverse rotation of the rotary handle drives the second locking member to slide towards the unlocking position, thereby realizing the control of the second locking member. In addition, there are many other possible implementation manners, which will not be elaborated here.

[0089] One embodiment of the present utility model corresponding to the control components being the knob 512 and the first turntable 51 structure is as follows: The pot lid assembly 20 further includes a check valve 61 provided on the pot lid body 21. The check valve 61 is disposed below the first turntable 51. A check valve hole 514 is formed on the first turntable 51. The check valve hole 514 is arranged as an arc structure around the center of the first turntable 51; The first valve hole end 514a of the check valve hole 514 corresponds to the locking section 511a, and the second valve hole end 514b of the check valve hole 514 corresponds to the position between the locking section 511a and the unlocking section 511b; When the valve core of the check valve 61 is placed at the first valve hole end 514a, the second locking member is placed at the end position of the locking section 511a; When the valve core of the check valve 61 is placed at the second valve hole end 514b, the second locking member is placed at the middle of the locking section 511a.

[0090] The design of the check valve 61 in this embodiment is equivalent to adding a safety device. The check valve 61 can limit the movement of the second locking member towards the unlocking position when the pressure in the pot body 10 is too high, avoiding the safety risks that may occur when opening the pot lid under high pressure.

[0091] On the basis of the check valve 61, the pot lid assembly 20 of the present utility model further is provided with an exhaust valve 62. The exhaust valve 62 includes a movably installed exhaust valve core 62 and a pushing member 63 connected to one side of the exhaust valve core 62. A groove opposite to the end of the pushing member 63 is provided on the first turntable 51. The side wall of the groove is provided with an inclined surface 515; When the second locking member is in the locking section, the rotation of the first turntable 51 can push the pushing member 63 through the inclined surface 515 to drive the movement of the exhaust valve core 62.

[0092] In use, the exhaust valve 62 serves as the first-stage air release device, which is suitable for exhausting when the pressure in the pot body 10 is -KPa. When the exhaust valve 62 fails to exhaust, the lid body 21 will float upward. The exhaust of the exhaust valve 62 is carried out by the user independently. The user can drive the first turntable 51 to rotate by rotating the knob 512. The rotation of the first turntable 51 can push up the valve core of the exhaust valve 62 through the pusher 63, thereby realizing exhaust. In this embodiment, the actions of the exhaust valve 62 and the first turntable 51 are combined with each other, making the connection between the components closer and the overall structure more compact.

[0093] The lid assembly 20 of the present utility model further includes a panel 24, which covers the lid body and can cover the first turntable 51, the air release bracket 22, and the second locking member. The knob 512 and the exhaust valve 62 have parts protruding from the panel 24. The protruding structure design of the knob 512 facilitates the operation of the user, and the panel 24 cover can improve the overall appearance of the lid assembly 20 and the pressure cooker. A handle 64 can also be provided on the outer side wall of the pot body 10 of the present utility model.

[0094] The structure of the pot body 10 of the present utility model may include a first straight cylinder 11, a tapered cylinder 12, a second straight cylinder 13, and a bottom plate 14 connected in sequence. One end of the first straight cylinder 11 forms an opening of the cooking cavity of the pot body 10, and an annular seal 23 is provided at the edge of the lid body 21; the inner side wall of the tapered cylinder 12 can be hermetically fitted with the seal 23.

[0095] The structure of the pot body 10 of the present utility model can be set in different forms. Refer to the structure of the pot body 10 in Figure 2 、 3 、7. The handle 64 of the pot body 10 can be set in different forms. It can be set as a plate-shaped structure where the handle 64 in Figure 3 is close to the opening of the pot body 10, and a depression for accommodating the edge of the lid is provided on the front surface of the handle 64. It can also be set as a rod-shaped structure in Figure 7 , which is provided in the middle of the pot body 10. The combination of the pot body 10 and the lid assembly 20 all belongs to the protection scope of the present utility model.

[0096] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the function and structural principle of the present utility model will be included in the scope of the claims.
