Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a cookware. Background Technology

[0002] Pressure cookers and electric pressure cookers, as cooking appliances, require internal pressure to operate. Different foods require different pressures. Currently, the pressure relief valves on pressure cookers on the market can only provide a fixed working pressure, resulting in insufficient internal pressure to meet the cooking needs of different foods and thus failing to satisfy user requirements. Utility Model Content

[0003] This application provides a cookware that can adjust the working pressure inside the pot according to different working conditions to meet the user's cooking needs.

[0004] This application provides a cookware, the cookware comprising: a pot body; a pot lid, the pot lid being able to cover the pot body, the pot lid comprising a lid body, the lid body being provided with an air inlet and a first exhaust channel communicating with the outside;

[0005] An exhaust valve includes a sealing element, a first elastic element, and a movable element. Along the height direction, one end of the first elastic element is connected to the sealing element, and the other end is connected to the movable element. The sealing element can move along the height direction to connect the air inlet with the first exhaust channel, or to isolate the air inlet from the first exhaust channel.

[0006] The pot lid also includes a driving component, which is connected to the moving component and is used to drive the moving component to move along the height direction.

[0007] In this design, when the sealing element moves away from the air inlet along the height direction, the air inlet connects with the first exhaust channel, and the gas inside the pot is discharged to the outside through the air inlet and the first exhaust channel. At this time, the exhaust valve is in the exhaust state. When the sealing element moves towards the air inlet along the height direction, the sealing element isolates the air inlet from the first exhaust channel, forming a sealed environment inside the pot. At this time, the exhaust valve is in the sealing state. This embodiment uses the movement of the sealing element along the height direction of the pot body to switch the exhaust valve between the exhaust state and the sealing state.

[0008] The driving component is connected to the moving component, which can drive the moving component to move along the height direction, thereby changing the deformation of the first elastic component between the moving component and the sealing component, so that the exhaust valve has at least a first state and a second state. When the exhaust valve is in the first state and the second state, the preset pressure of the exhaust valve is different. That is, when the exhaust valve is in the first state, the exhaust valve switches from the sealing state to the exhaust state when the pressure inside the pressure cooker reaches the first pressure. When the exhaust valve is in the second state, the exhaust valve switches from the sealing state to the exhaust state when the pressure inside the pressure cooker reaches the second pressure.

[0009] Therefore, the exhaust valve in this embodiment has at least two exhaust pressures, and the user can adjust the exhaust valve to the first state or the second state according to actual needs, thereby improving the user experience of the exhaust valve.

[0010] In addition, in this embodiment, the moving part can be driven by the driving part to move along the height direction of the exhaust valve, so as to change the elastic force of the first elastic element between the sealing part and the moving part, thereby switching the exhaust valve to different states, and thus realizing different pressures of the pressure cooker to meet the user's needs for cooking different ingredients.

[0011] In one possible design, the exhaust valve further includes a connector, at least a portion of which is elastically deformable, and the sealing element is mounted on the connector.

[0012] In this design, the elastically deformable parts of the sealing component and the connecting component are connected. When the pressure inside the pressure cooker is high, under the action of steam pressure, the sealing component can move in a direction away from the air inlet, thereby connecting the air inlet and the first exhaust channel. During this process, the elastically deformable connecting component allows the sealing component to move along the height of the cooker, and this connecting component improves the reliability of the sealing component's movement and its sensitivity to pressure inside the cooker.

[0013] In one possible design, the outer peripheral wall of the sealing member has a groove, the connector is provided with a first mounting hole, the sealing member is embedded in the first mounting hole, and the side wall of the first mounting hole is engaged with the groove.

[0014] In this solution, by designing the outer peripheral wall of the sealing component with a slot, and engaging the side wall of the first mounting hole of the connector within the slot, rapid positioning and mechanical interlocking of the sealing component and the connector are achieved. This effectively prevents relative displacement or separation due to vibration or external forces during assembly or use. Simultaneously, the tight fit between the slot and the side wall of the first mounting hole evenly distributes the pressure on the side wall, avoiding component deformation or failure caused by localized stress concentration, further enhancing the stability and reliability of the overall structure. Furthermore, this snap-fit ​​design eliminates the need for additional fasteners, simplifying the assembly process and reducing manufacturing costs. It is particularly suitable for space-constrained or frequently disassembled environments, facilitating equipment maintenance.

[0015] In one possible design, the inner wall of the slot is arc-shaped, and the side wall of the first mounting hole is arc-shaped.

[0016] In this design, by setting both the inner wall of the slot and the side wall of the first mounting hole as arc-shaped structures, the matching curvature of the two can form continuous surface contact during the snap-fit ​​process. This ensures that the load transfer path between the connector and the sealing component is evenly distributed circumferentially, effectively reducing local stress concentration at the contact interface and preventing plastic deformation or cracks caused by stress concentration, thereby extending the service life of the component. Furthermore, the matching arc-shaped structure can guide the side wall of the first mounting hole tangentially into the slot during assembly, achieving automatic centering and positioning, reducing assembly tolerance sensitivity, and ensuring consistency in mass production.

[0017] In one possible design, the connector includes a main body with a second exhaust channel between the main body and the cover, the second exhaust channel communicating with the first exhaust channel, and the axis of the first exhaust channel and the axis of the second exhaust channel having a non-zero angle; during the movement of the sealing member along the height direction, it can isolate the air inlet from the second exhaust channel, or connect the air inlet from the second exhaust channel.

[0018] In this design, when the exhaust valve is in the exhaust state, the gas discharged from the inlet can smoothly enter the first exhaust channel through the second exhaust channel between the main body of the connector and the lid. The connection between the second and first exhaust channels alters the gas's direction of movement, reducing the requirements for the inlet's position during cookware manufacturing. This ensures that even with slight deviations in the inlet's position, the gas can still smoothly pass through the second exhaust channel into the first exhaust channel for successful discharge, reducing instability during production. Furthermore, the relative bends between the first and second exhaust channels reduce noise during exhaust, improving the user experience. And because the sealing element is located on the connector, it can easily isolate or connect the second exhaust channel, ensuring a rapid and reliable response.

[0019] In one possible design, the connector further includes a sealing portion connected to the main body, the sealing portion sealing the position where the first exhaust passage connects to the second exhaust passage.

[0020] In this design, the sealing section seals the connection between the first and second exhaust channels, ensuring that gas can reliably and accurately enter the first exhaust channel through the second exhaust channel. This prevents moisture from escaping from the connection point and corroding other components. Furthermore, the sealing section ensures smooth and reliable venting, and extends the lifespan of the cookware.

[0021] In one possible design, the connector is made of silicone.

[0022] In this solution, since the sealing component moves some of the connecting components along the height direction during the use of the cookware, the use of silicone material can reduce the risk of fatigue fracture of the connecting components during long-term use and extend the service life of the cookware.

[0023] In one possible design, the lid further includes a display element comprising an indicator portion and a rod portion connected to the bottom of the indicator portion. The indicator portion has at least two different colors, and at least a portion of the indicator portion is located within the drive element. One end of the rod portion opposite to the indicator portion extends to the bottom of the lid body. The end of the rod portion opposite to the indicator portion is connected to a drive valve, which passes through the connector and the lid body. The drive valve is used to drive the rod portion to move up and down along the height direction to change the color of the indicator portion exposed to the drive element.

[0024] In this design, different colors distributed along the height of the indicator are used to represent different exhaust pressures. This article describes an example where the indicator is provided with a first color, a second color, and a third color, with the first color located above the second color and the third color located above the second color.

[0025] During cooking, when the steam pressure inside the pot is low, below the first pressure corresponding to the first color, no color is revealed. When the pressure inside the pot increases to the first pressure, the steam pressure causes the rod to move the indicator upward a first distance, revealing the first color above the drive component, allowing the user to know that the pressure inside the pot has increased to the first pressure. When the pressure inside the pot continues to increase to the second pressure, the steam pressure causes the rod to move the indicator upward a second distance, revealing the second color above the drive component, allowing the user to know that the pressure inside the pot has increased to the second pressure. When the pressure inside the pot continues to increase to the third pressure, the steam pressure causes the rod to move the indicator upward a third distance, revealing the third color above the drive component, allowing the user to know that the pressure inside the pot has increased to the third pressure, thus prompting the user to turn off the heat to prevent danger.

[0026] In one possible design, the drive valve includes a valve seat, a third elastic element, and a deformable element. The valve seat is fixed to the cover, and the rod passes through the valve seat. One end of the third elastic element is connected to the valve seat, and the other end is connected to the rod. The deformable element is installed on the cover and sleeved on the end of the rod. The deformable element is located below the cover and is capable of elastic deformation.

[0027] In this design, when the pressure inside the pot increases, the deformable part is squeezed under the pressure, causing it to shrink and deform. When the deformable part shrinks to contact the rod, the pressure of the steam causes the rod to drive the indicator to move upward. During this process, the rod and the valve seat compress the third elastic element. When the pressure inside the pot decreases, the deformable part gradually returns to its initial state, and the rod descends under the rebound force of the third elastic element.

[0028] In one possible design, the drive valve further includes a nut, the valve seat is threadedly connected to the nut, the connector further includes a connecting portion having a second through hole through which the valve seat passes, and the cover is held between the connector and the nut.

[0029] In this design, the threaded connection between the valve seat and the nut, along with the clamping of the connecting part between the cover and the nut, allows for simultaneous adjustment of the axial preload of the valve seat on the cover and the connecting part during nut tightening, ensuring a stable connection between the connecting part, the cover, and the valve seat. The threaded connection between the nut and the valve seat also enables quick assembly and disassembly of the drive valve, facilitating maintenance and replacement of parts.

[0030] In one possible design, the movable member has a first through hole, and the exhaust valve further includes a guide member, one end of which is connected to the sealing member, the other end of which passes through the first through hole, and the end of the guide member passing through the first through hole has an extension that can abut against the movable member.

[0031] In this design, the guide component passes through the first through hole of the moving component and connects to the sealing component. Its extended end abuts against the upper surface of the moving component, preventing the guide component from disengaging from the first through hole during the moving component's vertical movement. The first through hole also serves as a guide, ensuring the moving component always moves along a preset path, preventing deviation or wobbling. Simultaneously, one end of the guide component connects to the sealing component, guiding its movement along the height direction and preventing tilting or misalignment during movement, thus improving the accuracy of the air inlet's opening and closing action. This structure, through the mechanical cooperation of the guide component, the moving component, and the sealing component, simplifies the number of parts while achieving motion constraints, making the overall operation of the exhaust valve more stable and reliable. Furthermore, the design of the guide component passing through the first through hole facilitates assembly and positioning, reducing installation errors.

[0032] In one possible design, the movable member has an abutment portion for connection with the first elastic member, the first through hole being disposed in the abutment portion, the abutment portion being perpendicular to the height direction.

[0033] In this design, the abutting portion of the moving part is perpendicular to the height direction of the cookware, so that the pressure of the abutting portion on the first elastic member is along the height direction. This allows the first elastic member to elastically deform along the height direction, improving the reliability of the exhaust valve switching between exhaust and blocking states. When the guide member passes through the first through hole, the abutting portion provides lateral constraint for the relative movement between the moving part and the guide member, ensuring that the moving part does not tilt or deviate when moving along the height direction.

[0034] In one possible design, the movable component further includes a first body connected to the abutment portion, the first body having a tapered cross-section.

[0035] In this design, the first body has a conical cross-section, and the cavity inside the first body reduces interference to the lower components when the moving part moves up and down along the height. The abutment part is located at the top of the cone, and there is sufficient space in the height direction below it, which provides deformation space for the first elastic element, making the elastic reset action smoother and more reliable.

[0036] In one possible design, the cover has a first mounting portion that protrudes along the height direction relative to the cover. The sealing member is movably mounted within the first mounting portion, and a notch is provided between the abutment portion and the first body to allow for clearance from the first mounting portion. In this design, by setting the first mounting portion of the cover to protrude along the height direction, the sealing member can move stably within the protruding structure. Its inner wall forms a circumferential limit on the sealing member, preventing sealing failure caused by the sealing member's misalignment. Furthermore, the protruding structure of the first mounting portion provides precise guidance for the sealing fit between the sealing member and the air inlet, ensuring that the sealing member maintains alignment accuracy during vertical movement and improving the reliability of airflow control. Simultaneously, the notch design between the abutment portion and the first body provides clearance space for the first mounting portion, ensuring that the moving member does not structurally interfere with the first mounting portion during vertical movement.

[0037] In one possible design, the cover is connected to a seal, the air inlet is disposed on the seal, and the plug can abut against the seal to isolate the second exhaust passage from the air inlet.

[0038] In this design, by placing the air inlet on the sealing element of the cover and having the sealing element abut against it during movement, the connection between the air inlet and the second exhaust channel can be directly blocked. When the sealing element is pressed against the sealing element, the two fit tightly together to form a reliable seal, ensuring that gas cannot enter the second exhaust channel from the air inlet; when the sealing element is detached from the sealing element, the air inlet and the second exhaust channel are connected, and the gas can be quickly discharged. Because the sealing element protrudes relative to the cover, the sealing element only needs to move a small distance to abut against the sealing element and block the air inlet, thus isolating the second exhaust channel from the air inlet. This design controls the air passage opening and closing through direct contact between the sealing element and the sealing element, which simplifies the sealing structure, avoids wear or leakage problems caused by additional sealing components, improves the accuracy of the sealing action and the sealing stability, and extends the service life of the components.

[0039] In one possible design, the drive member has an inner cavity, the movable member is located within the inner cavity, and the movable member is threadedly connected to the drive member so that the movable member can be driven to move along the height direction during the rotation of the drive member.

[0040] In this design, by connecting the moving part and the driving part with a threaded connection, the helical transmission of the threaded pair converts the rotational motion of the driving part into a linear displacement of the moving part along the height direction when the driving part rotates. This design allows the driving part to move the moving part to any position within its range of motion, thereby adjusting the distance between the sealing part and the moving part, and consequently adjusting the elastic deformation of the first elastic element between them. This adjusts the exhaust pressure of the exhaust valve, enabling it to regulate the pressure inside the pot as needed under different working conditions, thus improving the pot's versatility. Furthermore, the moving part's location within the driving part's cavity optimizes space utilization, resulting in a compact overall structure that is easy to modularly assemble. Additionally, adjusting the thread lead allows for adaptation to different pressure regulation requirements, enhancing the design's versatility.

[0041] In one possible design, the lid further includes a rolling element and a second elastic element, one end of which is connected to the rolling element and the other end of which is connected to the lid body. The outer wall of the driving element has multiple grooves, and the rolling element can be positioned in each of the grooves during the rotation of the driving element relative to the lid body.

[0042] In this design, when the drive component rotates to a position where the rolling element abuts against the outer wall of the drive component (excluding the groove), the rolling element and the cover can compress the second elastic element under the action of the outer wall of the drive component. When the drive component rotates to a position where the rolling element aligns with the groove, the rebound force of the second elastic element can drive the rolling element into the groove, causing it to engage with the groove. The user needs to apply a relatively large external force to disengage the rolling element from the groove, reducing accidental rotation of the drive component caused by accidental activation. Simultaneously, when the rolling element enters the groove, it collides with the side wall of the groove, producing a sound that allows the user to perceive the movement of the drive component, thus facilitating the user's awareness of changes in the exhaust valve's gear position and improving the user experience. Furthermore, during the rotation of the drive component, the second elastic element can press the rolling element firmly against the side wall of the drive component, providing a tactile feedback when rotating the drive component and improving the user experience.

[0043] In one possible design, the cover includes a second mounting portion, the drive member is rotatably mounted on the second mounting portion, one end of the second elastic member is connected to the second mounting portion, and the second mounting portion includes a first part and a second part that are detachably connected.

[0044] In this design, the second mounting section is designed as a detachable combination of the first and second parts. During assembly, the rolling element and the second elastic element can be placed in the first and second parts first, and the drive element can be pre-installed in the first part. Subsequently, the second part is docked and locked to the first part. This allows the installation of the drive element, rolling element, and second elastic element to be completed without complex tooling, greatly simplifying the assembly process. Furthermore, the modular design of the first and second parts facilitates the individual replacement of the drive element, rolling element, or second elastic element during later maintenance, reducing maintenance costs. The rigid connection structure of the mating surfaces of the two parts ensures the overall load-bearing strength of the second mounting section while eliminating radial movement during drive element rotation, further improving positioning accuracy and operational feel during gear shifting.

[0129] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0130] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0131] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0132] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0133] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0134] like Figure 1 , Figure 2 , Figure 3 , Figure 14 As shown, this application embodiment provides a cookware, which includes a pot body 1 and a pot lid 2. The pot lid 2 can cover the opening of the pot body 1. The cookware also includes a lid body 21 and a vent valve 3, as shown. Figure 3 As shown, the cover 21 includes an air inlet 51 for venting gas from the pot, such as... Figure 4 As shown, the lid 21 also includes a first exhaust channel 2121 that communicates with the outside; the exhaust valve 3 is provided on the lid 21 and is used to open when the pressure inside the pressure cooker reaches the preset pressure during the cooking process, so as to realize the exhaust of the pressure cooker.

[0135] Among them, reference Figure 3 The exhaust valve 3 includes a sealing element 31, a first elastic element 32, and a moving element 33. Along the height direction, one end of the first elastic element 32 is connected to the sealing element 31, and the other end is connected to the moving element 33. The connection between the first elastic element 32 and the sealing element 31 can be a fixed connection such as abutment or adhesion, and the connection between the first elastic element 32 and the moving element 33 can also be a fixed connection such as abutment or adhesion. This application does not specifically limit the connection method between the first elastic element 32 and the sealing element 31 and the moving element 33.

[0136] The sealing element 31 can move along the height direction of the pot body 1. When the sealing element 31 moves away from the air inlet 51 along the height direction, the air inlet 51 is connected to the first exhaust channel 2121, and the gas inside the pot is discharged to the outside through the air inlet 51 and the first exhaust channel 2121. At this time, the exhaust valve 3 is in the exhaust state. When the sealing element 31 moves towards the air inlet 51 along the height direction, the sealing element 31 isolates the air inlet 51 and the first exhaust channel 2121, and a sealed environment is formed inside the pot. At this time, the exhaust valve 3 is in the sealing state. In this embodiment, the movement of the sealing element 31 along the height direction of the pot body 1 is used to switch the exhaust valve 3 between the exhaust state and the sealing state.

[0137] The pot lid 2 provided in this embodiment also includes a driving member 22, which is connected to a moving member 33. The driving member 22 can drive the moving member 33 to move along the height direction, thereby changing the deformation of the first elastic member 32 between the moving member 33 and the sealing member 31. This allows the exhaust valve 3 to have at least a first state and a second state. When the exhaust valve 3 is in the first state and the second state, the preset pressure for exhaust is different. That is, when the exhaust valve 3 is in the first state, the exhaust valve 3 switches from the sealing state to the exhaust state when the pressure inside the pressure pot reaches the first pressure; when the exhaust valve 3 is in the second state, the exhaust valve 3 switches from the sealing state to the exhaust state when the pressure inside the pressure pot reaches the second pressure. The following description uses the example of the second pressure being greater than the first pressure.

[0138] When cooking easily cooked foods (such as porridge), the drive unit 22 drives the moving part 33 to the first position, where the distance between the moving part 33 and the sealing part 31 is relatively large. When the pressure inside the pressure cooker is low, the exhaust valve 3 is in the first state of sealing, and the sealing part 31 blocks the air inlet 51. Steam inside the pressure cooker does not accumulate at the air inlet 51, and the steam pressure acting on the sealing part 31 is small, insufficient to drive the sealing part 31 to move away from the air inlet 51. As the pressure inside the pressure cooker gradually increases during cooking, when the pressure reaches the first pressure, under the action of the first pressure, the sealing part 31 moves away from the air inlet 51 under the action of air pressure, thereby opening the air inlet 51, so that the air inlet 51 is connected to the first exhaust channel 2121, and then connected to the outside to achieve exhaust. At this time, the exhaust valve 3 is in the first state of exhaust.

[0139] When cooking foods that are not easily cooked (such as meat), the drive unit 22 drives the moving part 33 to the second position, in which the distance between the moving part 33 and the sealing part 31 is small. When the pressure inside the pressure cooker is low, the exhaust valve 3 is in the second state of sealing, and the sealing part 31 blocks the air inlet 51. Steam inside the pressure cooker does not accumulate at the air inlet 51, and the steam pressure acting on the sealing part 31 is small, insufficient to drive the sealing part 31 to move away from the air inlet 51. As the pressure inside the pressure cooker gradually increases during cooking, when the pressure reaches the second pressure, under the action of the second pressure, the sealing part 31 moves away from the air inlet 51 under the action of air pressure, thereby opening the air inlet 51, so that the air inlet 51 is connected to the first exhaust channel 2121, and then connected to the outside, realizing exhaust. At this time, the exhaust valve 3 is in the second state of exhaust.

[0140] When the pressure cooker has three or more exhaust pressures, it is only necessary to adjust the position of the moving part 33 by driving part 22. This embodiment will not be described in detail.

[0141] In summary, when the exhaust valve 3 switches from the blocking state to the exhaust state in the first state, the exhaust pressure (first pressure) of the exhaust valve 3 needs to overcome the gravity of the blocking member 31 and the first elastic force of the first elastic member 32. When the exhaust valve 3 switches from the blocking state to the exhaust state in the second state, the exhaust pressure (second pressure) of the exhaust valve 3 needs to overcome the gravity of the blocking member 31 and the second elastic force of the first elastic member 32. Since the distance between the blocking member 31 and the moving member 33 is different in the first and second states, the first elastic force and the second elastic force of the first elastic member 32 are different, allowing the exhaust pressure of the exhaust valve 3 in the second state to be different from that in the first state. Therefore, the exhaust valve 3 in this embodiment has at least two exhaust pressures, allowing the user to adjust the exhaust valve 3 to be in the first or second state according to actual needs, thus improving the user experience of the exhaust valve 3.

[0142] In addition, in this embodiment, the moving part 33 can be driven by the driving part 22 to move along the height direction of the exhaust valve 3, so as to change the elastic force of the first elastic part 32 between the sealing part 31 and the moving part 33, thereby switching the exhaust valve 3 to the second state or the first state, thereby realizing different pressures of the pressure cooker to meet the user's needs for cooking different ingredients.

[0143] In some embodiments, such as Figure 2 , Figure 3 As shown, the exhaust valve 3 also includes a connector 34, at least a portion of which is elastically deformable, and a sealing member 31 is installed on the connector 34.

[0144] In this embodiment, the sealing member 31 and the connecting member 34 are connected by elastically deformable portions. When the pressure inside the pressure cooker is high, under the action of steam pressure, the sealing member 31 can move in a direction away from the air inlet 51, thereby connecting the air inlet 51 and the first exhaust channel 2121. During this process, the elastically deformable connecting member 34 allows the sealing member 31 to move along the height direction of the cooker, and the connecting member 34 can improve the reliability of the movement of the sealing member 31 and the sensitivity to the pressure response inside the cooker.

[0145] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the outer peripheral wall of the sealing member 31 has a groove 311, and the connector 34 is provided with a first mounting hole 341. The sealing member 31 is embedded in the first mounting hole 341, and the side wall of the first mounting hole 341 is engaged with the groove 311.

[0146] In this embodiment, by configuring the outer peripheral wall of the sealing member 31 with a slot 311, and engaging the side wall of the first mounting hole 341 of the connector 34 within the slot 311, rapid positioning and mechanical interlocking of the sealing member 31 and the connector 34 are achieved, effectively preventing relative displacement or separation due to vibration or external forces during assembly or use. Simultaneously, the tight fit between the slot 311 and the side wall of the first mounting hole 341 evenly distributes the pressure on the side wall of the first mounting hole 341, avoiding component deformation or failure caused by localized stress concentration, further improving the stability and reliability of the overall structure. Furthermore, this snap-fit ​​design eliminates the need for additional fasteners to achieve self-locking, simplifying the assembly process and reducing manufacturing costs. It is particularly suitable for work environments with limited space or requiring frequent disassembly and assembly, providing convenience for equipment maintenance.

[0147] Specifically, the inner wall of the slot 311 is arc-shaped, and the side wall of the first mounting hole 341 is arc-shaped.

[0148] In this embodiment, by setting both the inner wall of the slot 311 and the side wall of the first mounting hole 341 as arc-shaped structures, the matching curvature of the two can form continuous surface contact during the snap-fit ​​process. This ensures that the load transfer path between the connector 34 and the sealing member 31 is evenly distributed circumferentially, effectively reducing local stress concentration at the contact interface and avoiding plastic deformation or cracks caused by stress concentration, thereby extending the service life of the component. In addition, the matching arc-shaped structure can guide the side wall of the first mounting hole 341 tangentially into the slot 311 during assembly, achieving automatic centering and positioning, reducing assembly tolerance sensitivity, and ensuring consistency in mass production.

[0149] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the connector 34 includes a main body 342, which forms a second exhaust channel 4 with the cover 21. The second exhaust channel 4 is connected to the first exhaust channel 2121, and the axis of the first exhaust channel 2121 and the axis of the second exhaust channel 4 have a non-zero angle. During the movement of the sealing member 31 along the height direction, it can isolate the air inlet 51 from the second exhaust channel 4, or connect the air inlet 51 and the second exhaust channel 4. The first exhaust channel 2121 and the second exhaust channel 4 are relatively bent, meaning that the axis of the first exhaust channel 2121 and the axis of the second exhaust channel 4 are located on different straight lines.

[0150] In this embodiment, when the exhaust valve 3 is in the exhaust state, the gas discharged from the air inlet 51 can smoothly enter the first exhaust channel 2121 through the second exhaust channel 4 between the main body 342 of the connector 34 and the cover 21 and then be discharged. The axis of the first exhaust channel 2121 and the axis of the second exhaust channel 4 have a non-zero angle, meaning that the second exhaust channel 4 is connected to the first exhaust channel 2121, which can change the direction of gas movement. This reduces the requirements for the position setting of the air inlet 51 during cookware manufacturing, allowing the gas to still smoothly pass through the second exhaust channel 4 and be discharged smoothly into the first exhaust channel 2121 even with slight deviations in the position of the air inlet 51, thus reducing instability during the manufacturing process. Furthermore, the relative bending of the first exhaust channel 2121 and the second exhaust channel 4 can also reduce noise during the exhaust process, improving the user experience of the cookware. And since the sealing member 31 is located on the connector 34, it is convenient for the sealing member 31 to isolate or connect the second exhaust channel 4, making its response rapid and reliable.

[0151] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the main body 342 is provided with a connecting port 3421, which is connected to the first exhaust channel 2121. When the steam pressure inside the pressure cooker reaches the exhaust pressure, under the action of the steam pressure, the sealing member 31 moves away from the air inlet 51, so that the steam enters the second exhaust channel 4 between the main body 342 and the cover 21 of the connector 34 through the air inlet 51, and then enters the first exhaust channel 2121 through the connecting port 3421, and is then discharged to the outside from the first exhaust channel 2121.

[0152] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the connector 34 may also include a sealing part 343 connected to the main body 342, which seals the position where the first exhaust channel 2121 and the second exhaust channel 4 are connected.

[0153] In this embodiment, the sealing part 343 seals the connection between the first exhaust channel 2121 and the second exhaust channel 4, allowing gas to enter the first exhaust channel 2121 stably and accurately through the second exhaust channel 4. This prevents moisture from escaping from the connection between the first exhaust channel 2121 and the second exhaust channel 4, which could corrode other components. Furthermore, the sealing part 343 ensures smooth and reliable exhaust flow and extends the lifespan of the cookware.

[0154] Among them, such as Figure 4 As shown, a receiving space 345 is formed between the sealing part 343 and the main body 342. A part of the cover 21 can be located in the receiving space 345, thereby clamping a part of the cover 21 by the sealing part 343 and the main body 342, thereby sealing the connection position between the first exhaust channel 2121 and the second exhaust channel 4.

[0155] In the above embodiments, as Figure 2 , Figure 7 As shown, the cover 21 includes a first cover 211 and a second cover 212, wherein the second cover 212 can be located above the first cover 211, and the two can be detachably connected. The aforementioned first exhaust channel 2121 is disposed on the second cover 212.

[0156] like Figure 8 As shown, the second cover 212 has a mounting groove 2122 on the side facing the first cover 211. The connector 34 can be embedded in the mounting groove 2122, thus ensuring the connector 34 is in a stable position and is less prone to displacement. This improves the stability and reliability of the cookware during long-term use and extends its service life. Furthermore, when the connector 34 is installed in the mounting groove 2122, the connecting port 3421 of the connector 34 connects with the 2121 of the second cover 212, enabling communication between the first exhaust channel 2121 and the second exhaust channel 4.

[0157] In the above embodiments, the connector 34 can be made of elastically deformable silicone material. Since the sealing component 31 drives part of the connector 34 to move along the height direction during the use of the cookware, using silicone material can reduce the risk of fatigue fracture of the connector 34 during long-term use, thus extending the service life of the cookware.

[0158] In some embodiments, such as Figure 3 , Figure 9 As shown, the cover 21 is connected to a sealing element 5, the air inlet 51 is disposed on the sealing element 5, and the sealing element 31 abuts against the sealing element 5 to isolate the second exhaust channel 4 and the air inlet 51.

[0159] In this embodiment, reference Figure 3By placing the air inlet 51 on the sealing element 5 of the cover 21 and having the sealing element 31 abut against the sealing element 5 when it moves, the connection between the air inlet 51 and the second exhaust channel 4 can be directly blocked. When the sealing element 31 abuts against the sealing element 5, the two fit tightly together to form a reliable seal, ensuring that gas cannot enter the second exhaust channel 4 from the air inlet 51; when the sealing element 31 detaches from the sealing element 5, the air inlet 51 connects with the second exhaust channel 4, and the gas can be quickly discharged. Since the sealing element 5 protrudes relative to the cover 21, the sealing element 31 only needs to move a small distance to abut against the sealing element 5 and block the air inlet 51, thus isolating the second exhaust channel 4 from the air inlet 51. This design controls the opening and closing of the air passage through the direct contact between the sealing element 31 and the sealing element 5, which simplifies the sealing structure, avoids wear or leakage problems caused by additional sealing components, improves the accuracy of the sealing action and the sealing stability, and extends the service life of the components.

[0160] The specific structure of the driving component 22 and the moving component 33 is described in detail below.

[0161] In some embodiments, such as Figure 3 , Figure 10 , Figure 11 As shown, the driving member 22 has an inner cavity 221, and the moving member 33 is located in the inner cavity 221 and is threadedly connected to the moving member 33. During the rotation of the driving member 22, it can drive the moving member 33 to move along the height direction.

[0162] In this embodiment, by connecting the movable part 33 and the driving part 22 with a threaded connection, the helical transmission of the threaded pair can convert the rotational motion of the driving part 22 into a linear displacement of the movable part 33 along the height direction when the driving part 22 rotates. Through this design, the driving part 22 can drive the movable part 33 to any position within its movement range, thereby adjusting the distance between the sealing part 31 and the movable part 33, and further adjusting the elastic deformation of the first elastic element 32 between the sealing part 31 and the movable part 33, thus adjusting the exhaust pressure of the exhaust valve 3. This allows the exhaust valve 3 to adjust the pressure inside the pot as needed under different working conditions, improving the versatility of the cookware under various conditions. Furthermore, the movable part 33 being located within the inner cavity 221 of the driving part 22 optimizes space utilization, resulting in a compact overall structure that is easy to modularly assemble. Simultaneously, by adjusting the thread lead, it can adapt to different pressure adjustment requirements, enhancing the design's versatility.

[0163] In some embodiments, such as Figure 11 , Figure 12 , Figure 14 , Figure 15As shown, the movable member 33 also has a first through hole 3311, and the exhaust valve 3 includes a guide member 35. One end of the guide member 35 is connected to the sealing member 31, and the other end passes through the first through hole 3311. The end passing through the first through hole 3311 has an extension 351, which can abut against the movable member 33 to limit the displacement of the guide member 35.

[0164] In this embodiment, the guide member 35 passes through the first through hole 3311 of the movable member 33 and connects to the sealing member 31. Its extended portion 351 at its end abuts against the upper surface of the movable member 33, thus preventing the guide member 35 from disengaging from the first through hole 3311 when the movable member 33 moves up and down. The first through hole 3311 also serves as a guide, ensuring the movable member 33 always moves along a preset path, preventing deviation or shaking. Simultaneously, one end of the guide member 35 connects to the sealing member 31, guiding the movement of the sealing member 31 along the height direction, preventing tilting or misalignment during movement, and improving the accuracy of the opening and closing of the air inlet 51. This structure, through the mechanical cooperation of the guide member 35 with the movable member 33 and the sealing member 31, simplifies the number of parts while achieving motion constraints, making the overall operation of the exhaust valve 3 more stable and reliable. Furthermore, the design of the guide member 35 passing through the first through hole 3311 facilitates assembly and positioning, reducing installation errors.

[0165] In some embodiments, such as Figure 11 , Figure 12 , Figure 14 As shown, the movable member 33 has an abutment portion 331 connected to the first elastic member 32, a first through hole 3311 is provided in the abutment portion 331, and the abutment portion 331 is perpendicular to the height direction of the pot.

[0166] In this embodiment, the abutment portion 331 of the movable member 33 is arranged perpendicular to the height direction of the cookware, so that the pressure of the abutment portion 331 on the first elastic member 32 is along the height direction, thereby enabling the first elastic member 32 to elastically deform along the height direction, improving the reliability of the exhaust valve 3 in switching between the exhaust state and the blocking state. When the guide member 35 passes through the first through hole 3311, the abutment portion 331 provides lateral constraint for the relative movement between the movable member 33 and the guide member 35, ensuring that the movable member 33 will not tilt or deviate when moving along the height direction.

[0167] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 As shown, the movable member 33 also includes a first body 332 connected to the abutment portion 331, and the cross-section of the first body 332 is conical.

[0168] In this embodiment, the cross-section of the first body 332 is conical. The cavity formed inside the first body 332 can reduce the interference of the moving part 33 to its lower part when it moves up and down along the height. The abutting part 331 is located at the top of the cone, and there is sufficient space in the height direction below it, which reserves deformation space for the first elastic member 32 to make the elastic reset action smoother and more reliable.

[0169] In some embodiments, such as Figure 11 , Figure 12 , Figure 14 , Figure 16 As shown, the cover 21 has a first mounting portion 23 that protrudes in the height direction relative to the cover 21. The sealing member 31 is movably disposed inside the first mounting portion 23, that is, the sealing member 31 can move in the height direction within the first mounting portion 23. The abutting portion 331 and the first body 332 have a notch 334 to avoid the first mounting portion 23.

[0170] In this embodiment, by protruding the first mounting portion 23 of the cover 21 along the height direction, the sealing member 31 can move stably within the protruding structure. Its inner wall provides circumferential restraint to the sealing member 31, preventing sealing failure caused by misalignment. Furthermore, the protruding structure of the first mounting portion 23 provides precise guidance for the sealing fit between the sealing member 31 and the air inlet 51, ensuring the sealing member 31 maintains alignment accuracy during vertical movement and improving the reliability of airflow control. Simultaneously, the notch 334 between the abutment portion 331 and the first body 332 provides clearance space for the first mounting portion 23, ensuring that the moving member 33 does not structurally interfere with the first mounting portion 23 during vertical movement.

[0171] Since the contact portion 331 is perpendicular to the height direction of the pot and the first body 332 is conical, the first body 332 gradually moves away from the contact portion 331 in a direction away from its center. The notch 334 is located between the contact portion 331 and the first body 332 in the height direction, and the notch 334 is located between the contact portion 331 and the first body 332 in the circumferential direction.

[0172] The specific structure of the drive component 22 is described in detail below.

[0173] In some embodiments, such as Figure 3 As shown, the pot lid 2 also includes a rolling element 24 and a second elastic element 25. One end of the second elastic element 25 is connected to the rolling element 24, and the other end is connected to the lid body 21. (Refer to...) Figure 10 The outer wall of the drive member 22 has multiple grooves 222. During the rotation of the drive member 22 relative to the cover 21, the rolling member 24 can be located inside each groove 222.

[0174] In this embodiment, when the drive member 22 rotates to a position where the rolling member 24 abuts against the outer wall of the drive member 22 (excluding the groove 222), the rolling member 24 and the cover 21 can compress the second elastic member 25 under the action of the outer wall of the drive member 22. When the drive member 22 rotates to a position where the rolling member 24 is aligned with the groove 222, the rebound force of the second elastic member 25 can drive the rolling member 24 into the groove 222, causing the rolling member 24 to engage with the groove 222. The user needs to apply a large external force to disengage the rolling member 24 from the groove 222, reducing the rotation of the drive member 22 caused by accidental activation. At the same time, when the rolling member 24 enters the groove 222, the rolling member 24 can collide with the side wall of the groove 222 to produce a sound, allowing the user to perceive the movement of the drive member 22, thereby facilitating the user's perception of the gear change of the exhaust valve 3 and improving the user experience. In addition, during the rotation of the drive member 22, the second elastic member 25 can press the rolling member 24 against the side wall of the drive member 22, providing a tactile feel for rotating the drive member 22 and improving the user experience.

[0175] In addition, such as Figure 10 As shown, an operating part 223 is connected to the outer wall of the drive member 22, which is used by the user to operate the drive member 22 to rotate.

[0176] In some embodiments, such as Figure 3 , Figure 17 As shown, the cover 21 may also include a second mounting portion 26, a driving member 22 is rotatably mounted on the second mounting portion 26, one end of the second elastic member 25 is connected to the second mounting portion 26, and the second mounting portion 26 includes a first part 261 and a second part 262 that are detachably connected.

[0177] In this embodiment, by designing the second mounting portion 26 as a detachable combination of the first part 261 and the second part 262, during assembly, the rolling element 24 and the second elastic element 25 can be first placed on the first part 261 and the second part 262, and then the driving element 22 can be pre-installed on the first part 261. Subsequently, the second part 262 is docked and locked to the first part 261. This allows the installation of the driving element 22, the rolling element 24, and the second elastic element 25 to be completed without complex tooling, greatly simplifying the assembly process. At the same time, the modular disassembly and assembly design of the first part 261 and the second part 262 facilitates the individual replacement of the driving element 22, the rolling element 24, or the second elastic element 25 during later maintenance, reducing maintenance costs. The rigid connection structure of the two mating surfaces ensures the overall load-bearing strength of the second mounting portion 26 while eliminating radial movement of the driving element 22 during rotation, further improving the positioning accuracy and operating feel during gear shifting.

[0178] The first part 261 and the second part 262 can be connected by snap-fit ​​or pin, etc. This application does not specifically limit the detachable connection method of the first part 261 and the second part 262. When the first part 261 and the second part 262 are connected, they can form a circular space, and the driving component 22 is placed in the circular space and can rotate in the circular space.

[0179] The second mounting part 26 can be detachably connected to the second cover 212, that is, the cover 21 includes a first cover 211, a second cover 212 and a second mounting part 26 that can be detachably connected, thereby facilitating the installation of components such as the drive unit 22, the exhaust valve 3, and the connector 34 on the cover 21.

[0180] In some embodiments, such as Figure 18 , Figure 19 , Figure 20 As shown, the pot lid 2 may also include a display element 27, on which an indicator 271 is provided. The indicator 271 has at least two different colors, and the at least two different colors are distributed along the height direction. A portion of the display element 27 is located inside the drive element 22, and a rod 272 is connected to the bottom of the display element 27. One end of the rod 272 away from the display element 27 extends to the bottom of the lid 21. The end of the rod 272 away from the display element 27 has a drive valve 6. The drive valve 6 passes through the connector 34 and the lid 21. The drive valve 6 is used to drive the rod 272 to move up and down along the height direction, so that the indicator 271 is exposed with different colors from above the drive element 22.

[0181] In this embodiment, different colors distributed along the height direction on the indicator 271 are used to represent different exhaust pressures. This article describes an example where the indicator 271 is provided with a first color, a second color, and a third color, with the first color located above the second color and the third color located above the second color.

[0182] During cooking, when the steam pressure inside the pot 1 is low, below the first pressure corresponding to the first color, no color is revealed. When the pressure inside the pot 1 increases to the first pressure, the steam pressure causes the rod 272 to move the indicator 271 upward a first distance, causing the first color to be revealed above the drive member 22, allowing the user to know that the pressure inside the pot 1 has increased to the first pressure. When the pressure inside the pot 1 continues to increase to the second pressure, the steam pressure causes the rod 272 to move the indicator 271 upward a second distance, causing the second color to be revealed above the drive member 22, allowing the user to know that the pressure inside the pot 1 has increased to the second pressure. When the pressure inside the pot 1 continues to increase to the third pressure, the steam pressure causes the rod 272 to move the indicator 271 upward a third distance, causing the third color to be revealed above the drive member 22, allowing the user to know that the pressure inside the pot 1 has increased to the third pressure, thus prompting the user to turn off the heat to prevent danger.

[0183] For example, the first color can be green, and the corresponding first pressure can be 85 kP for the first cover 211; the second color can be yellow, and the corresponding second pressure can be 105 kP for the first cover 211; the third color can be red, and the corresponding third pressure can be 120 kP for the first cover 211.

[0184] Therefore, the display 27 in this embodiment can indicate the pressure inside the pot 1 to the user, preventing danger.

[0185] In some embodiments, such as Figure 20 , Figure 21 As shown, the drive valve 6 includes a valve seat 61, a third elastic member 62, and a deformable member 63. The valve seat 61 is fixed to the cover 21, and the rod 272 of the display member 27 passes through the valve seat 61. One end of the third elastic member 62 is connected to the valve seat 61, and the other end is connected to the rod 272. The deformable member 63 is installed on the cover 21 and sleeved on the end of the rod 272. The deformable member 63 is located below the cover 21 and can be elastically deformed.

[0186] In this embodiment, when the pressure inside the pot increases, the deformable member 63 is squeezed under the pressure, causing it to contract and deform. When the deformable member 63 contracts to contact the rod 272, the pressure of the steam causes the rod 272 to drive the indicator 271 upward. During this process, the rod 272 and the valve seat 61 compress the third elastic member 62. When the pressure inside the pot 1 decreases, the deformable member 63 gradually returns to its initial state, and the rod 272 descends under the rebound force of the third elastic member 62.

[0187] Therefore, the drive valve 6 can automatically raise and lower the indicator 271 to indicate the pressure inside the pot 1. The deformable part 63 not only transmits the steam pressure to the rod 272, but also protects the rod 272 from corrosion caused by long-term contact with steam. The elastic preload of the third elastic part 62 and the deformation of the deformable part 63 form a dynamic balance, making the lifting stroke of the rod 272 and the pressure value have a relatively accurate linear correspondence. This allows for precise feedback on small displacements during low-pressure stages and ensures that the indicator 271 quickly rises to the warning position when high-pressure is triggered. The axial constraint of the valve seat 61 on the rod 272, combined with the sealing effect of the deformable part 63, ensures the integrity of the sealing interface while determining the direction of movement of the rod 272. This allows for accurate transmission of the pressure inside the pot, and the third elastic part 62 can react promptly to pressure changes, allowing the rod 272 to gradually return to its original position when the pressure decreases. This provides structural stability and accuracy for long-term use.

[0188] In some embodiments, such as Figure 20 As shown, the drive valve 6 may also include a nut 64, and the valve seat 61 and the nut 64 are connected by threads, in combination. Figure 4 , Figure 5 The connector 34 also includes a connecting part 344, on which a second through hole 3441 is provided. The valve seat 61 passes through the second through hole 3441, and the cover 21 is clamped between the connector 34 and the nut 64.

[0189] In this embodiment, the threaded connection between the valve seat 61 and the nut 64, and the clamping of the connecting part 344 between the cover 21 and the nut 64, allow for simultaneous adjustment of the axial preload of the valve seat 61 on the cover 21 and the connecting part 344 during the tightening of the nut 64. This ensures a stable connection between the connecting part 34, the cover 21, and the valve seat 61. The threaded connection between the nut 64 and the valve seat 61 also enables quick disassembly and assembly of the drive valve 6, facilitating the repair and replacement of parts during maintenance.

[0190] In one specific embodiment, such as Figure 21 As shown, the outer wall of the valve seat 61 has at least one abutment surface 611, which is a plane.

[0191] In this embodiment, the abutting surface 611 of the outer wall of the valve seat 61 abuts against the plane of the inner surface of the first fixing hole 2111 on the first cover 211 and the second fixing hole 2124 on the second cover 212. The plane of the inner surface of the first fixing hole 2111 and the second fixing hole 2124 provides a constraint for the valve seat 61, which can limit the valve seat 61 from rotating along its axial direction and ensure the reliability of the valve seat 61 during operation.

[0192] In one specific embodiment, such as Figure 1 , Figure 22As shown, the cover 21 is also provided with a pull rod 8, which includes a pivot part 812. The second cover 212 has a mating part 2125 that cooperates with the pivot. The pivot and the mating part 2125 cooperate to fix the pull rod 8 to the second cover 212 so that the pull rod 8 can move.

[0193] In this embodiment, the pull rod 8 can rotate along the pivot 812. After the pull rod 8 rotates to a certain angle, the user can easily grasp the pull rod 8 to pick up the entire pot. The design of the pull rod 8 allows the user to operate the pot with one hand, freeing up one hand and making operation convenient, thus improving the practicality and portability of the pot.

[0194] Specifically, the pull rod 8 is divided into an upper pull rod 81 and a lower pull rod 82. The pivot part 812 is provided on the upper pull rod 81. The upper pull rod 81 is provided with a protrusion 811 that extends radially outward along the pot. The lower pull rod 82 has a variety of optional colors, such as green, red, blue, yellow, etc.

[0195] The protrusion 811 on the lever 8 allows the user to easily separate the lever 8 from the cover 21 by pulling it up, facilitating operation. The pull rod 82 offers a variety of color options, providing both simple decoration and visual appeal. This aesthetically pleasing design aims to increase the user's willingness to purchase.

[0196] In some embodiments, such as Figure 2 , Figure 23 As shown, the cookware also includes an anti-clogging cover 7, which has multiple third through holes 71 and through grooves 72 with small cross-sectional areas.

[0197] In this embodiment, the anti-blocking cover 7 is located below the cover 21, between the pot body 1 and the air inlet 51. When the cookware is in operation, the gas inside the pot body 1 first passes through the anti-blocking cover 7, and then enters the exhaust channel through the air inlet 51 and is discharged. Because the anti-blocking cover has multiple small-section third through holes 71 and through grooves 72, and the cross-sectional area of ​​the third through holes 71 and through grooves 72 is small, the gas can be smoothly discharged through the third through holes 71 and through grooves 72, while larger food pieces inside the pot cannot pass through the third through holes 71 and through grooves 72. This reduces the occurrence of food pieces blocking the air inlet 51 and causing exhaust failure, thus improving the safety of the cookware during use and the reliability of the exhaust process.

[0198] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
