Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a pot lid assembly and a pressure cooking appliance. Background Technology

[0002] Pressure cooking appliances typically consist of a pot body and a lid. The lid includes an inner lid and a liner located above the inner lid. When the lid is closed, the inner lid and the pot body form a cooking chamber. During pressure cooking, because the pressure inside the cooking chamber is higher than the external atmospheric pressure, the gas inside the pot exerts an upward pushing force on the inner lid, which in turn exerts an upward force on the liner. The inner lid, as the component directly exposed to the high-pressure environment and the high-temperature steam inside the pot, is usually made of metal. However, to save costs, the liner is mostly made of plastic, which has lower structural strength. Therefore, under the greater pushing force of the inner lid, there is a risk that the liner may deform or be damaged.

[0003] Therefore, some pressure cookers incorporate reinforcing plates and other structural components in their lids to provide structural support. To ensure the structural strength of the reinforcing plates, metal components are typically used. Thus, during assembly, the plastic lid must be fitted with the metal reinforcing plate. Additionally, the lid often houses many functional structural components, such as temperature sensors.

[0004] The liner has a relatively complex structure, with each functional component assembled relatively independently. However, due to the addition of a reinforcing plate, ensuring effective fit between the components and the liner and reinforcing plate is a significant challenge in the structural design. Current technologies often use clips, screws, or other methods to fix the functional components to the liner. This method not only results in high material costs and complex assembly procedures, but also makes it easy for components to interfere with the reinforcing plate, increasing the difficulty of installing the reinforcing plate and even affecting its supporting effect on the liner.

[0005] Therefore, improving the overall structural consistency and assembly feasibility of the liner is an urgent problem to be solved in this field. Utility Model Content

[0006] This utility model provides a pot lid assembly and a pressure cooking appliance to solve the problems of high assembly difficulty, high material cost, and low overall structural consistency and assembly feasibility of the pot lid, which are caused by the functional components on the pot lid being installed independently on the liner.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A pot lid assembly includes a liner and an inner cover located below the liner. The inner cover cooperates with the pot body to form a cooking cavity. The pot lid assembly also includes a reinforcing member and a temperature measuring member. The reinforcing member is used to support the liner to withstand the force exerted by the inner cover on the liner. The temperature measuring member is fixed to the upper side of the liner and passes downward through the liner. The reinforcing member is fixed to the side of the liner away from the inner cover and located above the temperature measuring member. The reinforcing member and the liner cooperate to clamp and fix the temperature measuring member.

[0009] The pot lid assembly of this utility model also has the following additional technical features:

[0010] The temperature measuring element includes a fixed base and a downwardly extending temperature probe. The fixed base is located above the liner, and the temperature probe passes through the liner. The upper surface of the liner is provided with a positioning groove, and the reinforcing member presses and fixes the fixed base in the positioning groove.

[0011] One of the bottom wall of the positioning sink and the fixed seat is provided with a limiting protrusion, and the other is provided with a limiting structure that plugs into the limiting protrusion to restrict the movement of the fixed seat relative to the positioning sink.

[0012] The liner has a mating groove on the side opposite to the inner cover. The pot lid assembly also includes a locking member and a pressure plate. The reinforcing member presses the pressure plate to cover the mating groove to form a mounting cavity. The locking member is located in the mounting cavity and can move within the mounting cavity to lock the inner cover to the liner, or to unlock the inner cover from the liner.

[0013] The liner is provided with an upwardly protruding fixing buckle, and the pressure plate is provided with a snap-fit ​​groove. The fixing buckle and the snap-fit ​​groove cooperate with each other. The pressure plate is also provided with an abutment part. The reinforcing member presses against the abutment part. The abutment part and the snap-fit ​​groove are located on opposite sides of the pressure plate.

[0014] The reinforcing member has a downwardly extending pressing protrusion, and the abutting part is provided with a receiving groove that mates with the pressing protrusion, with the pressing protrusion extending into the receiving groove.

[0015] The locking component includes a guide portion and a fixing groove located above the guide portion. The edge of the inner cover is accommodated in the fixing groove to be fixed with the liner. The lower surface of the guide portion is provided with a guide transition surface.

[0016] The temperature measuring element has a mounting base located above the cover, the mounting base has connecting terminals, and the reinforcing member has a wiring port corresponding to the connecting terminals.

[0017] The liner has a front region and a rear region. The rear region is provided with a connecting arm for rotating connection with the pot body, and the front region is provided with a snap-fit ​​part for locking with the pot body. The reinforcing member extends from the front region to the rear region.

[0018] This utility model also discloses a pressure cooking appliance, including a pot body and an inner pot placed inside the pot body, and also includes the aforementioned pot lid assembly. The inner lid covers the inner pot so that the inner lid and the inner pot cooperate to form a cooking cavity, and the lower end of the temperature measuring element passes through the inner lid to extend into the cooking cavity.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0020] 1. In this utility model, the temperature measuring element is placed on the upper side of the liner. The temperature measuring element is clamped between the reinforcing element and the liner, thus fixing the element in place. Firstly, it eliminates the need for separate assembly of the temperature measuring element with the liner or reinforcing element, saving the design of fasteners such as clips or screws, achieving a stable fixation of the temperature measuring element. Simultaneously, the pressing action of the reinforcing element ensures the temperature measuring element is tightly fitted to the upper surface of the liner, guaranteeing a compact assembly. Secondly, it greatly simplifies the assembly steps of the pot lid assembly. Only the reinforcing element and the liner need to be assembled; the clamping force between them fixes the temperature measuring element, thereby improving the structural consistency of the temperature measuring element, reinforcing element, and liner, significantly saving material costs and increasing assembly efficiency.

[0021] 2. In a preferred embodiment of this utility model, the temperature measuring element includes a fixed base and a downwardly extending temperature probe. The fixed base is located above the liner, and the temperature probe passes through the liner. A positioning groove is provided on the upper surface of the liner, and a reinforcing member presses and fixes the fixed base within the positioning groove. The positioning groove not only positions the temperature measuring element during installation but also limits its movement after assembly, preventing it from shifting under the pressure of the reinforcing member. Specifically, during assembly, the fixed base is first placed in the positioning groove, where the sidewall of the groove forms a stop, confining the fixed base within the groove. Then, the reinforcing member is fastened to the liner. Under the pre-tightening force between the reinforcing member and the liner, the reinforcing member firmly presses the temperature measuring element into the positioning groove, and the element does not undergo horizontal displacement during the pressure applied by the reinforcing member, ensuring positional stability. Meanwhile, since at least a portion of the mounting base is accommodated within the positioning groove, the fit between the reinforcing member and the liner is improved, enhancing the reinforcing member's support for the liner and reducing the overall thickness of the lid assembly, thus improving structural compactness.

[0022] 3. In a preferred embodiment of this utility model, one of the bottom wall of the positioning groove and the fixing seat is provided with a limiting protrusion, and the other is provided with a limiting structure that engages with the limiting protrusion to restrict the movement of the fixing seat relative to the positioning groove. The engagement of the limiting protrusion and the limiting structure further improves the positioning and fixing effect of the temperature measuring element. The engagement of the limiting protrusion and the limiting structure, once completed, restricts the movement of the fixing seat within the positioning groove, thus keeping the temperature measuring element in a fixed position.

[0023] 4. In a preferred embodiment of this utility model, the liner has a mating groove on the side opposite to the inner cover. The pot lid assembly also includes a locking member and a pressure plate. The reinforcing member presses the pressure plate to cover the mating groove to form an installation cavity. The locking member is disposed in the installation cavity and can move within the installation cavity to lock the inner cover to the liner or unlock the inner cover from the liner. In this embodiment, the liner is also provided with a locking member, which can lock the inner cover to the liner or unlock it from the inner cover, allowing the inner cover to be removed from the liner, thereby realizing the detachable design of the inner cover. By pressing the pressure plate down with the reinforcing member to mate with the mating groove of the liner to form an installation cavity for installing the locking member, the assembly of the pressure plate and other structures is also simplified. There is no need to design a separate fixing structure to fix the pressure plate to the liner. Instead, the pressure plate is fixed by the fastening force of the reinforcing member and the liner. Therefore, during assembly, it is only necessary to place the pressure plate in the preset position and then directly fasten the reinforcing member to the liner to fix the pressure plate, which simplifies the assembly steps and saves costs.

[0024] 5. In a preferred embodiment of this utility model, the liner has a front region and a rear region. The rear region is provided with a connecting arm for rotatably connecting with the pot body, and the front region is provided with a snap-fit ​​part for locking with the pot body. The reinforcing member extends from the front region to the rear region. The connecting arm in the rear region of the liner is used for rotatably connecting with the pot body, and the snap-fit ​​part in the front region is used for locking with the pot body. When the gas pressure inside the pot rises, the gas inside the pot pushes the lid to move upwards. However, because the snap-fit ​​part in the front region is locked with the pot body, and the connecting arm in the rear region is connected with the pot body, the front and rear of the liner are restricted. Therefore, the front and rear regions are also very prone to deformation or damage, requiring high structural strength. In this embodiment, the reinforcing member extends from the front region to the rear region. Therefore, the reinforcing member can not only provide structural reinforcement to the area where the inner cover acts on the liner, but also provide structural reinforcement to the snap-fit ​​part in the front region of the liner and the connecting arm in the rear region. This improves the overall strength of each stress point of the liner, giving the reinforcing member multiple uses without the need for additional reinforcing structures, simplifying the structure of the liner and saving costs.

[0044] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] Furthermore, it should be understood in the description of this utility model that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] like Figure 1 , Figure 2 , Figure 7 As shown, a pot lid assembly includes a liner 1 and an inner cover 6 located below the liner 1. The inner cover 6 cooperates with the pot body to form a cooking cavity. The pot lid assembly also includes a reinforcing member 2 and a temperature measuring member 3. The reinforcing member 2 is used to support the liner 1 to withstand the force exerted by the inner cover 6 on the liner 1. The temperature measuring member 3 is fixed to the upper side of the liner 1 and passes downward through the liner 1. The reinforcing member 2 is fixed to the side of the liner 1 away from the inner cover 6 and is located above the temperature measuring member 3. The reinforcing member 2 cooperates with the liner 1 to clamp and fix the temperature measuring member 3.

[0050] In this invention, the temperature measuring element 3 is placed on the upper side of the liner 1. The temperature measuring element 3 is clamped between the reinforcing element 2 and the liner 1, thus fixing the temperature measuring element 3. Firstly, it eliminates the need to separately assemble the temperature measuring element 3 with the liner 1 or the reinforcing element 2, saving the design of fasteners such as clips or screws, achieving a stable fixation of the temperature measuring element 3. Simultaneously, the pressing action of the reinforcing element 2 ensures that the temperature measuring element 3 is tightly fitted to the upper surface of the liner 1, guaranteeing a compact assembly. Secondly, it greatly simplifies the assembly steps of the pot lid assembly. Only the reinforcing element 2 and the liner 1 need to be assembled; the clamping force between them can then be used to fix the temperature measuring element 3, thereby improving the structural consistency of the temperature measuring element 3 with the reinforcing element 2 and the liner 1, significantly saving material costs and improving assembly efficiency.

[0051] In addition, the temperature measuring element 3 is fixed to the side of the liner 1 away from the inner cover 6, making it more difficult for steam and other substances in the pot to reach the fixed position of the temperature measuring element 3 during cooking. This reduces the erosion of the fixed position by steam, ensuring cleanliness and improving the reliability of the fixation.

[0052] It should be noted that, in addition to the temperature measuring component 3, other functional components can also be provided between the reinforcing component 2 and the liner 1, such as pressure holding and pressure relief components, buckle components for locking with the pot body, locking components for locking with the inner cover 6, etc. These functional components do not require additional fixing structures. Similarly, by using the fastening of the reinforcing component 2 and the liner 1, the reinforcing component 2 and the liner 1 can clamp and fix each functional component, so that the installation of each functional component can be completed simultaneously with only the assembly of the reinforcing component 2 and the liner 1, thereby further reducing the assembly difficulty and improving the assembly efficiency.

[0053] As a preferred embodiment of this utility model, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the temperature measuring element 3 includes a fixed base 32 and a downwardly extending temperature measuring probe 31. The fixed base 32 is located above the cover 1, and the temperature measuring probe 31 passes through the cover 1. The upper surface of the cover 1 is provided with a positioning groove 11, and the reinforcing member 2 presses and fixes the fixed base 32 in the positioning groove 11.

[0054] The positioning groove 11 not only positions the temperature measuring element 3 during installation but also limits its movement after assembly, preventing it from shifting under the pressure of the reinforcing member 2. Specifically, during assembly, the fixing seat 32 is first placed within the positioning groove 11. The sidewall of the positioning groove 11 then acts as a stop for the fixing seat 32, confining it within the groove. Next, the reinforcing member 2 is securely connected to the cover 1. Under the pre-tightening force between the reinforcing member 2 and the cover 1, the reinforcing member 2 firmly presses the temperature measuring element 3 into the positioning groove 11. Furthermore, the temperature measuring element 3 does not undergo horizontal displacement during the pressure applied by the reinforcing member 2, ensuring positional stability. Simultaneously, since at least a portion of the fixing seat 32 is housed within the positioning groove 11, the fit between the reinforcing member 2 and the cover 1 is improved, enhancing the support effect of the reinforcing member 2 on the cover 1. This also reduces the overall thickness of the pot lid assembly, improving structural compactness.

[0055] It should be noted that this embodiment does not limit the shape of the positioning groove 11 and the fixing seat 32. In a preferred embodiment, such as Figure 9 As shown, both the positioning groove 11 and the fixing base 32 are non-circular structures, for example... Figure 9 The square shape shown in the figure allows the fixed seat 32 to be placed in the positioning groove 11. The groove wall of the positioning groove 11 can not only limit the lateral movement of the fixed seat 32, but also restrict the rotation of the fixed seat 32 in the positioning groove 11, so as to further improve the positional stability of the temperature measuring element 3.

[0056] Of course, the positioning groove 11 and the fixing seat 32 can also be other shapes, such as circles, triangles, pentagons, etc., which are not limited here.

[0057] Furthermore, such as Figures 7 to 9 As shown, one of the bottom wall of the positioning groove 11 and the fixed seat 32 is provided with a limiting protrusion 111, and the other is provided with a limiting structure that is inserted and engaged with the limiting protrusion 111 to restrict the movement of the fixed seat 32 relative to the positioning groove 11.

[0058] By cooperating with the limiting protrusion 111, the positioning and fixing effect of the temperature measuring element 3 can be further improved. The limiting protrusion 111 and the limiting structure are inserted and cooperated. After the cooperation is completed, the fixed seat 32 can be restricted from moving in the positioning groove 11, so that the temperature measuring element 3 can be kept in a fixed position.

[0059] Specifically, such as Figure 9 As shown, there are two limiting structures and limiting protrusions 111, which are arranged opposite to each other on both sides of the temperature probe 31.

[0060] In one specific embodiment, such as Figure 7 , Figure 9As shown, the limiting protrusion 111 is disposed on the bottom wall of the positioning groove 11 and protrudes upward. The limiting structure is a limiting hole 321 that penetrates the fixing seat 32. When the fixing seat 32 is placed in the positioning groove 11, the limiting protrusion 111 and the limiting hole 321 are inserted and engaged. In other embodiments, the limiting structure can also be a groove structure or a column structure, as long as it can be inserted and engaged with the limiting protrusion 111, which is not limited here. Of course, the limiting protrusion 111 can also be disposed on the fixing seat 32, and the limiting structure can be disposed on the bottom wall of the positioning groove 11, which is also not limited.

[0061] Preferably, such as Figures 1 to 5 As shown, the liner 1 has a mating groove 12 on the side opposite to the inner cover 6. The pot lid assembly also includes a locking member 5 and a pressure plate 4. The reinforcing member 2 presses the pressure plate 4 to cover the mating groove 12 to form an installation cavity 121. The locking member 5 is disposed in the installation cavity 121 and can move in the installation cavity 121 to lock the inner cover 6 to the liner 1, or to unlock the inner cover 6 from the liner 1.

[0062] In this embodiment, the liner 1 is also provided with a locking member 5, which can lock the inner cover 6 to the liner 1 or unlock it, allowing the inner cover 6 to be removed from the liner 1. This achieves a detachable design for the inner cover 6, making it convenient for users to clean the inner cover 6 separately. By pressing down the pressure plate 4 with the reinforcing member 2, it mates with the mating groove 12 of the liner 1 to form an installation cavity 121 for installing the locking member 5. This also simplifies the assembly of the pressure plate 4 and other structures. There is no need to design a separate fixing structure to fix the pressure plate 4 to the liner 1. Instead, the pressure plate 4 is fixed by the fastening force between the reinforcing member 2 and the liner 1. Therefore, during assembly, it is only necessary to place the pressure plate 4 in the preset position and then directly fasten the reinforcing member 2 to the liner 1 to fix the pressure plate 4, which simplifies the assembly steps and saves costs.

[0063] Specifically, such as Figure 3 , Figure 5 As shown, the mounting cavity 121 extends radially along the cover 1, and the locking member 5 can reciprocate radially along the cover 1. Figure 5As shown, the center of the cover 1 has a mounting position for installing the inner cover 6, and the mounting cavity 121 and the locking member 5 are located outside the mounting position. The locking member 5 has a guide post 53 on the side facing the mounting cavity 121, and an elastic member 7 is sleeved on the outer periphery of the guide post 53. The elastic member 7 applies a radially inward force to the locking member 5 along the cover 1. A fixing groove 51 is provided on the side of the locking member 5 away from the mounting cavity 121. When the inner cover 6 is installed into the mounting position, the edge of the inner cover 6 pushes against the locking member 5, causing the locking member 5 to overcome the elastic force of the elastic member 7 and move radially outward along the cover 1, which is also moving into the mounting cavity 121. At this time, the locking member 5 avoids the inner cover 6, and the elastic member 7 is compressed. After the inner cover 6 is installed in place, its edge corresponds to the position of the fixing groove 51. At this time, the inner cover 6 loses its pushing force on the locking member 5. Under the action of the elastic member 7, the locking member 5 moves radially inward along the liner 1, so that the fixing groove 51 and the edge of the inner cover 6 are engaged. Under the elastic force of the elastic member 7, the inner cover 6 is clamped, thus locking the inner cover 6 and the liner 1. When removing the inner cover 6, control the locking member 5 to move radially outward along the liner 1 to loosen it from the inner cover 6. At this time, the inner cover 6 can be removed.

[0064] Furthermore, such as Figure 5 As shown, a guide portion is provided below the fixing groove 51, and a guide transition surface 52 is provided on the lower surface of the guide portion. The guide transition surface 52 gradually extends upward in a radially inward direction along the liner 1, so that when installing the inner cover 6, the inner cover 6 is aligned with the mounting position on the liner 1, and the inner cover 6 is simply pushed upward (towards the liner 1). After the edge of the inner cover 6 contacts the guide transition surface 52, the guide transition surface 52 will convert the upward force of the inner cover 6 into a lateral thrust, causing the locking member 5 to move outward. This makes the installation of the inner cover 6 simpler and more convenient, improving the user experience.

[0065] Specifically, the guide transition surface 52 can be an inclined surface, a circular arc surface, or other irregular curved surfaces, without limitation.

[0066] As a preferred embodiment of this implementation, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the cover 1 is provided with an upwardly protruding fixing buckle 13, the pressure plate 4 is provided with a snap-fit ​​groove 41, the fixing buckle 13 cooperates with the snap-fit ​​groove 41, the pressure plate 4 is also provided with an abutting part, the reinforcing member 2 presses the abutting part, and the abutting part and the snap-fit ​​groove 41 are located on opposite sides of the pressure plate 4.

[0067] One end of the pressure plate 4 is fixed by engaging with the fixing buckle 13 through the snap-fit ​​groove 41, while the other end is fixed by the pressure of the reinforcing member 2. Both ends are restricted, which makes the fixing of the pressure plate 4 more reliable and stable, reducing the probability of the pressure plate 4 tilting or loosening. Specifically, the snap-fit ​​groove 41 is located at the end away from the center of the cover 1, and the abutment part is located at the end closer to the center of the cover 1.

[0068] Furthermore, such as Figures 2 to 5 As shown, the reinforcing member 2 has a downwardly extending pressing protrusion 22, and the abutting part is provided with a receiving groove 42 that mates with the pressing protrusion 22, with the pressing protrusion 22 extending into the receiving groove 42.

[0069] The pressing protrusion 22 engages with the receiving groove 42, making their contact more stable, preventing slippage during pressing and improving pressing reliability. Specifically, for example... Figure 5 As shown, the receiving groove 42 extends in the horizontal plane in a direction perpendicular to the radial direction of the cover 1 to compensate for machining errors and assembly errors, and to ensure that the pressing protrusion 22 can extend into the receiving groove 42 to complete the fit.

[0070] As a preferred embodiment of this utility model, such as Figure 1 , Figure 4 , Figure 10 As shown, the temperature measuring element 3 has a fixing seat 32 located above the cover 1, the fixing seat 32 has a connecting terminal, and the reinforcing element 2 has a wiring port 21 corresponding to the connecting terminal.

[0071] The wiring port 21 allows the temperature sensor 3 to be connected via the wiring port 21 after the reinforcing member 2 is fixed to the cover 1. This facilitates wiring and allows the wires to run through the side space on the reinforcing member 2, preventing bending or damage due to pressure from the reinforcing member 2. Simultaneously, the wiring port 21 also facilitates heat dissipation from the mounting base 32, preventing excessive temperature rise at the connection terminals. Preferably, the area of ​​the wiring port 21 is larger than the wiring terminal but smaller than the mounting base 32.

[0072] Preferably, such as Figure 10 As shown, the liner 1 has a front region 14 and a rear region 15. The rear region 15 is provided with a connecting arm for rotating connection with the pot body, and the front region 14 is provided with a snap-fit ​​part for locking with the pot body. The reinforcing member 2 extends from the front region 14 to the rear region 15.

[0073] The connecting arm of the rear region 15 of the liner 1 is used for rotatable connection with the pot body, and the snap-fit ​​part of the front region 14 is used for locking with the pot body. When the gas pressure inside the pot rises, the gas inside the pot pushes the lid to move upward. Since the snap-fit ​​part of the front region 14 is locked with the pot body and the connecting arm of the rear region 15 is connected with the pot body, the front and rear of the liner 1 are restricted. Therefore, the front region 14 and the rear region 15 are also very prone to deformation or damage, requiring high structural strength. In this embodiment, the reinforcing member 2 extends from the front region 14 to the rear region 15. Therefore, the reinforcing member 2 can not only provide structural reinforcement for the area where the inner cover 6 acts on the liner 1, but also provide structural reinforcement for the snap-fit ​​part of the front region 14 and the connecting arm of the rear region 15 of the liner 1. This improves the overall strength of the liner 1 at each stress point, giving the reinforcing member 2 multiple uses without the need for additional reinforcing structures, simplifying the structure of the liner 1 and saving costs.

[0074] Preferably, the reinforcing member 2 is fixedly connected to the cover 1 by screws to further improve the connection stability and support stability of the two. Under the pre-tightening force of the screws, the reinforcing member 2 can be pressed tightly against the upper surface of the cover 1, which not only improves the fixing stability of components such as the temperature measuring element 3, but also improves the support of the reinforcing member 2 for the cover 1, effectively improving the structural strength of the cover 1.

[0075] This utility model also discloses a pressure cooking appliance, including a pot body and an inner pot placed inside the pot body, and also includes the aforementioned pot lid assembly. The inner lid 6 covers the inner pot so that the inner lid 6 and the inner pot cooperate to form a cooking cavity, and the lower end of the temperature measuring element 3 passes through the inner lid 6 to extend into the cooking cavity.

[0076] The temperature measuring element 3 extends into the cooking cavity and comes into direct contact with the cooking environment, thereby enabling direct detection of the temperature inside the pot and improving detection accuracy.

[0077] It should be noted that the pressure cooking appliance of this utility model can be a high-pressure cooking appliance, such as a pressure cooker, or a low-pressure cooking appliance, such as a low-pressure rice cooker, as long as it can cook in an environment with pressure higher than atmospheric pressure.

[0078] Preferably, such as Figure 10 As shown, the liner 1 has a connecting end located in the rear region 15 and an opening and closing end located in the front region 14. The connecting end is rotatably connected to the pot body, and the opening and closing end is provided with a buckle part, which can lock with the front end of the pot body. The pot lid assembly can be flipped up and down around the connecting point to open or close the lid.

[0079] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0080] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
