[0049] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0050] like Figure 1 Zhongzhi Figure 9As shown, a pressure cooking appliance is proposed according to an embodiment of this disclosure, including: a pot body assembly 100; and a pot lid assembly 200, including a first lid portion 210 and a second lid portion 220. The first lid portion 210 is disposed on the pot body assembly 100 and is used to lock and unlock with the pot body assembly 100. A transition cavity 201 is formed between the second lid portion 220 and the first lid portion 210, and a cooking cavity 101 is formed between the second lid portion 220 and the pot body assembly 100. A sealing ring is provided between the periphery of the 0 and the pot body assembly 100; an exhaust assembly 300 is provided in the first cover portion 210; an anti-blocking assembly 400 is provided in the transition cavity 201 and has a filter hole 401; wherein, the transition cavity 201 is connected between the filter hole 401 and the cooking cavity 101, the air inlet end of the exhaust assembly 300 is connected to the transition cavity 201 through the filter hole 401, the second cover portion 220 has an overflow hole 2201, and the transition cavity 201 is connected to the cooking cavity 101 through the overflow hole 2201.

[0051] The pressure cooking appliance provided in this embodiment includes a pot body assembly 100, a lid assembly 200, an exhaust assembly 300, and an anti-clogging assembly 400. A cooking chamber 101 is formed between the pot body assembly 100 and the lid assembly 200, which can be used to hold food to be cooked. A transition chamber 201 is formed within the lid assembly 200. The exhaust assembly 300 is disposed on the lid assembly 200 and can be used to connect the cooking chamber 101 with the external environment to allow the cooking chamber 101 to release pressure. The anti-clogging assembly 400 has a filter hole 401 and is disposed within the transition chamber 201. The air inlet of the exhaust assembly 300 can be connected to the transition chamber 201 through the filter hole 401, and the filter hole 401 can be connected to the cooking chamber 100 through the transition chamber 201. 1. Thus, when the exhaust assembly 300 is turned on, the gas in the cooking chamber 101 can flow sequentially through the transition chamber 201 and the filter hole 401 to the air inlet of the exhaust assembly 300. When flowing through the connection between the cooking chamber 101 and the transition chamber 201 and the aforementioned filter hole 401, it can come into contact with the lid assembly 200 and the anti-blocking assembly 400 respectively. Moreover, the air bubbles carried by the gas are also likely to come into contact with the lid assembly 200 and the anti-blocking assembly 400 at the corresponding positions, thereby increasing the probability of the air bubbles bursting. This reduces the possibility of air bubbles accumulating at or entering the air inlet of the exhaust assembly 300, ensuring the exhaust effect of the exhaust assembly 300 and reducing the risk of liquid overflowing through the exhaust assembly 300 after the air bubbles burst. This also reduces the cleaning burden of pressure cooking appliances and improves the user experience of the product.

[0052] The aforementioned lid assembly 200 may include a first lid portion 210 and a second lid portion 220. The aforementioned transition cavity 201 is formed between the first lid portion 210 and the second lid portion 220. When the lid assembly 200 covers the opening of the pot body assembly 100, the aforementioned cooking cavity 101 can be formed between the second lid portion 220 and the pot body assembly 100. Correspondingly, the second lid portion 220 is located between the cooking cavity 101 and the transition cavity 201. A sealing ring is provided between the periphery of the second lid portion 220 and the pot body assembly 100. Thus, when the aforementioned cooking cavity 101 is formed between the second lid portion 220 and the pot body assembly 100, the lid assembly 200 can form a circumferential sealing fit with the pot body assembly 100, and the aforementioned sealing ring seals the space between the lid assembly 200 and the pot body assembly 100. The circumferential fit clearance helps to improve the environmental stability of the cooking cavity 101 during cooking and reduce the risk of overflow from the pressure cooking appliance; the second cover part 220 has an overflow hole 2201, which can provide a conduction path for the cooking cavity 101 and the transition cavity 201. It is also convenient to constrain the conduction area between the cooking cavity 101 and the transition cavity 201 by controlling the size parameters of the overflow hole 2201, thereby reducing the conduction area between the cooking cavity 101 and the transition cavity 201. This helps to further increase the probability of bubbles contacting the lid assembly 200 when flowing through the connection between the cooking cavity 101 and the transition cavity 201, thereby improving the bubble breaking effect of the lid assembly 200, reducing the amount of bubbles in the transition cavity 201, and reducing the possibility of bubbles accumulating at or entering the air inlet of the exhaust assembly 300.

[0053] Furthermore, based on the aforementioned configuration, the aforementioned anti-blocking component 400 is located between the aforementioned first cover portion 210 and second cover portion 220. Thus, when the fluid in the cooking cavity 101 flows towards the air inlet of the exhaust component 300, it needs to pass through the second cover portion 220 and the anti-blocking component 400 in sequence. It is understood that the aforementioned fluid includes, but is not limited to, gas, liquid and air bubbles. Therefore, the pressure cooking appliance of this disclosure can intercept and break air bubbles in multiple layers during the exhaust process, enhance the effect of the pressure cooking appliance in intercepting and breaking air bubbles, and further reduce the possibility of air bubbles accumulating at or entering the air inlet of the exhaust component 300. Meanwhile, since the second cover portion 220 can form the aforementioned cooking cavity 101 with the pot body assembly 100, that is, the second cover portion 220 can cover the pot opening of the pot body assembly 100, the coverage area of ​​the second cover portion 220 over the cooking cavity 101 is relatively large. Therefore, compared with the method of specifically covering the air inlet end of the exhaust assembly 300 with a bubble-breaking cover, on the one hand, the second cover portion 220 can have a larger contact area with the fluid, and thus, during the exhaust and depressurization process, the second cover portion 220 can have a higher probability of contacting bubbles. It is understandable that during the exhaust and depressurization process of a pressure cooking appliance, a wide range and a large number of bubbles are easily generated in the cooking cavity 101, and the bubbles move towards the exhaust assembly 300. During the flow process, the second cover portion 220 is more likely to come into contact with the fluid first. As a result, with a larger contact area between the second cover portion 220 and the fluid, the second cover portion 220 can have a higher efficiency in intercepting and breaking bubbles, reducing the number of bubbles entering the transition cavity 201, which helps to reduce the bubble breaking burden on the anti-clogging component 400. On the other hand, it also makes it easier for the second cover portion 220 to distribute the force during use, so that the second cover portion 220 can have stronger pressure resistance and impact resistance. Compared with the aforementioned bubble breaking cover, it is more suitable for breaking and intercepting bubbles during the depressurization process of pressure cooking appliances, and can buffer the fluid flowing towards the anti-clogging component 400, which helps to reduce the impact of the fluid on the anti-clogging component 400.

[0054] It is understood that the aforementioned pot body assembly 100 has a pot opening, and the aforementioned pot lid assembly 200 can be used to cover or open the pot opening. The first lid portion 210 is used to lock and unlock with the pot body assembly 100. During cooking, the first lid portion 210 can be locked to the pot body assembly 100, thereby preventing the pot lid assembly 200 from opening and ensuring the stable and safe operation of the pressure cooking process. Correspondingly, after cooking, the first lid portion 210 can be unlocked to facilitate the user's consumption or cleaning of the pressure cooking appliance. When the pot lid assembly 200 covers the pot opening, the second lid portion 220 forms the aforementioned cooking cavity 101 with the pot body assembly 100, and can be sealed with the pot body assembly 100 by the aforementioned sealing ring.

[0055] It is understood that the connection between the aforementioned first cover portion 210 and the aforementioned pot body assembly 100 can take many forms, such as a movable connection or a detachable connection, etc., and no further limitations are imposed here. Correspondingly, there can also be many ways to lock and unlock the aforementioned first cover portion 210 and pot body assembly, and no further limitations are imposed here.

[0056] Understandably, in practical applications, the first cover portion 210 can be used as the outer cover of the pot lid assembly 200, thereby improving the aesthetics and structural reliability of the pot lid assembly 200. Correspondingly, the second cover portion 220 can be used as the inner cover of the pot lid assembly 200, so that the pot lid assembly 200 can use the second cover portion 220 to structurally cooperate with the pot body assembly 100 to form the aforementioned cooking cavity 101, and is conducive to ensuring the sealing of the cooking cavity 101 during the cooking process.

[0057] It is understandable that the aperture or cross-sectional area of ​​the aforementioned flow passage 2201 can be selected according to actual needs. For example, if the flow passage 2201 needs to have good passage, the aperture or cross-sectional area of ​​the flow passage 2201 can be set to be larger. If the second cover part 220 needs to have a high bubble breaking effect, the aperture or cross-sectional area of ​​the flow passage 2201 can be set to be smaller. The specific aperture or cross-sectional area values ​​are not limited here.

[0058] It is understandable that the shape of the aforementioned flow passage 2201 can be various, such as circular, elliptical, polygonal, waist-shaped, etc. The specific shape can be selected according to actual needs, and no further restrictions are imposed here.

[0059] It is understood that there can be multiple flow holes 2201, and the specific number of flow holes 2201 can be selected according to actual needs. No further restrictions are imposed here.

[0060] It is understandable that, based on the aforementioned transition cavity 201, the path of gas flow from the cooking cavity 101 to the air inlet of the exhaust assembly 300 can be extended, thereby increasing the probability of bubbles naturally bursting during their movement toward the exhaust assembly 300.

[0061] It is understood that the aforementioned anti-clogging component 400 may be in the form of, but is not limited to, a cover-shaped, annular, or tubular structure. Correspondingly, the air inlet end of the exhaust component 300 may be located inside the anti-clogging component 400. Thus, when the anti-clogging component 400 is located inside the transition chamber 201, the anti-clogging component 400 can isolate the transition chamber 201 and the air inlet end of the cooking component to a certain extent. The aforementioned filter hole 401 can connect the inner and outer sides of the anti-clogging component 400, so that the air inlet end of the exhaust component 300 can be connected to the transition chamber 201 through the filter hole 401, thereby improving the anti-clogging component 400's effect on breaking bubbles and reducing the possibility of bubbles accumulating at or entering the air inlet end of the exhaust component 300.

[0062] Understandably, when the exhaust assembly 300 is venting, if the solid food in the cooking cavity 101 is affected by pressure and moves towards the exhaust assembly 300, the anti-blocking assembly 400 can block the aforementioned solid food, preventing it from entering the exhaust assembly 300 and reducing the risk of blockage of the exhaust assembly 300.

[0063] It is understood that the aforementioned exhaust assembly 300 may include a pressure relief valve, so that after pressure cooking is completed, the exhaust assembly 300 can release the pressure of the cooking chamber 101 by venting through the pressure relief valve.

[0064] like Figure 2 and Figure 4 As shown, in some examples, the anti-blocking component 400 and the lid assembly 200 are an integral structure; or the anti-blocking component 400 and the lid assembly 200 are separate structures, with the anti-blocking component 400 connected to the venting component 300 or the lid assembly 200.

[0065] In this technical solution, such as Figure 2 As shown, the anti-blocking component 400 and the pot lid component 200 can be set as an integrated structure, which can reduce the installation difficulty of the anti-blocking component 400 and improve the positional stability of the anti-blocking component 400. This is conducive to maintaining a stable and reliable positional relationship between the anti-blocking component 400 and the exhaust component 300, thereby ensuring the anti-blocking component 400's effect on breaking bubbles and further reducing the possibility of bubbles accumulating at or entering the air intake end of the exhaust component 300.

[0066] Alternatively, the anti-blocking component 400 and the lid component 200 can be configured as separate structures, with the anti-blocking component 400 connected to the exhaust component 300 or the lid component 200. This can improve the layout flexibility of the anti-blocking component 400 and the structural flexibility of the lid component 200, and help save on the design and manufacturing costs of the lid component 200.

[0067] It is understood that the aforementioned anti-blocking component 400 and pot lid component 200 are an integral structure, meaning that at least a portion of the anti-blocking component 400 and pot lid component 200 are integral. In practical applications, the anti-blocking component 400 can be integrally formed into the pot lid component 200, for example, by processing the pot lid component 200 and the anti-blocking component 400 together through sheet metal, stamping, casting, or other processes; or, the anti-blocking component 400 can be connected to the pot lid component 200 as an integral unit through welding or other methods. There are multiple ways to achieve the integral structure of the anti-blocking component 400 and the pot lid component 200, and the specific implementation method can be selected according to actual needs, without further limitations here.

[0068] It is understood that the aforementioned anti-blocking component 400 and pot lid component 200 are separate structures, meaning that the anti-blocking component 400 and pot lid component 200 are structurally independent or detachable. Accordingly, the anti-blocking component 400 can be directly or indirectly connected to the exhaust component 300, or directly or indirectly connected to the pot lid component 200.

[0069] like Figure 2 As shown, in some examples, the anti-clogging component 400 includes: an annular rib 410 with a filter hole 401, one end of the filter hole 401 being located on the outer peripheral wall of the annular rib 410, and the other end of the filter hole 401 being located on the inner peripheral wall of the annular rib 410, the inner peripheral wall of the annular rib 410 being arranged around the air intake end of the exhaust component 300; wherein, the two ends of the annular rib 410 are respectively connected to the first cover portion 210 and the second cover portion 220.

[0070] In this technical solution, the aforementioned anti-clogging component 400 may include an annular rib 410, and the aforementioned filter hole 401 is formed on the aforementioned annular rib 410 with its two ends located on the inner and outer peripheral walls of the annular rib 410, respectively. Thus, the filter hole 401 can conduct the space on the inner and outer sides of the annular rib 410 in the circumferential direction. Correspondingly, the annular rib 410 can be disposed within the aforementioned transition cavity 201 and arranged around the air inlet end of the exhaust assembly 300, so that the air inlet end of the exhaust assembly 300 is located on the inner side of the annular rib 410 in the circumferential direction and can... The transition chamber 201 is connected via the aforementioned filter hole 401. When the exhaust assembly 300 exhausts air, the air inlet can access the airflow within the transition chamber 201 through the filter hole 401. If the airflow carries air bubbles, these bubbles are easily broken by the annular rib 410, reducing the likelihood of bubbles accumulating or entering the air inlet of the exhaust assembly 300. This ensures the pressure relief efficiency of the pressure cooking appliance and reduces the probability of liquid overflow from the exhaust assembly 300, improving the cleanliness and reliability of the pressure cooking appliance. The two ends of the annular rib 410 can be connected to the first cover portion 210 and the second cover portion 220, respectively. The first cover portion 210 and the second cover portion 220 can cover the open ends of the annular rib 410, further constraining and limiting the conduction path between the inner and outer spaces of the annular rib 410 in the circumferential direction. This allows more airflow in the transition chamber 201 to flow through the filter hole 401 to the air inlet of the exhaust assembly 300, thereby increasing the probability of air bubbles being broken by the annular rib 410.

[0071] It is understood that the two ends of the aforementioned annular rib 410 refer to the two ends of the annular rib 410 in the axial direction; the shape of the aforementioned annular rib 410 can be, but is not limited to, a circular ring, for example, it can also be a polygonal ring, an elliptical ring, etc. The specific shape of the annular rib 410 is not limited here.

[0072] like Figure 2 As shown, in some examples, the second cover portion 220 is detachably connected to the exhaust assembly 300, and the annular rib 410 and the second cover portion 220 are integrally formed; when the second cover portion 220 is connected to the exhaust assembly 300, the second cover portion 220 and the first cover portion 210 form a transition cavity 201, the end of the annular rib 410 away from the second cover portion 220 abuts against the first cover portion 210, and the inner peripheral wall of the annular rib 410 surrounds the air intake end of the exhaust assembly 300.

[0073] In this technical solution, such as Figure 2As shown, the second cover portion 220 can be connected to the first cover portion 210 via the exhaust assembly 300, and the second cover portion 220 and the exhaust assembly 300 can be detachably connected. Accordingly, when the second cover portion 220 is connected to the exhaust assembly 300, the aforementioned transition cavity 201 can be formed between the first cover portion 210 and the second cover portion 220. When the second cover portion 220 is removed from the exhaust assembly 300, the transition cavity 201 is opened, thereby facilitating the cleaning and maintenance of the first cover portion 210, the second cover portion 220, the exhaust assembly 300, and the anti-clogging assembly 400. The aforementioned annular rib 410 can be an integral structure with the second cover portion 220, so that the annular rib 410 can be integrated with the second cover portion 210. The second cover portion 220 is simultaneously installed and removed from the exhaust assembly 300. When the second cover portion 220 is connected to the exhaust assembly 300, the end of the annular rib 410 away from the second cover portion 220 can abut against the first cover portion 210. The inner peripheral wall of the annular rib 410 surrounds the air inlet end of the exhaust assembly 300. Based on this, on the one hand, the installation difficulty of the anti-clogging component 400 can be reduced, and when the second cover portion 220 is connected to the exhaust assembly 300, the positional stability of the anti-clogging component 400 can be improved, which is conducive to maintaining a stable and reliable positional relationship between the anti-clogging component 400 and the exhaust assembly 300. On the other hand, it can also facilitate the disassembly and cleaning of the annular rib 410, reduce the cleaning difficulty of the pressure cooking appliance, and ensure the cleanliness of the pressure cooking appliance.

[0074] It is understood that the aforementioned annular rib 410 and the second cover portion 220 are an integral structure, meaning that at least a portion of the annular rib 410 and the second cover portion 220 are integral. In practical applications, the annular rib 410 can be integrally formed into the second cover portion 220, for example, by sheet metal, stamping, casting, or other processes. Alternatively, the annular rib 410 can be connected to the second cover portion 220 by welding or other methods. There are various ways to achieve the integral structure of the annular rib 410 and the second cover portion 220, and the specific implementation method can be selected according to actual needs. No further limitations are imposed here.

[0075] like Figure 2 As shown, in some examples, an interlayer space 4101 is formed between the inner peripheral wall of the annular rib 410 and the outer peripheral wall of the annular rib 410, and the interlayer space 4101 is connected to the filter hole 401.

[0076] In this technical solution, an interlayer space 4101 can be formed between the inner peripheral wall and the outer peripheral wall of the annular rib 410. The aforementioned filter hole 401 can communicate with the interlayer space 4101. Based on the aforementioned arrangement, when the exhaust assembly 300 exhausts, the annular rib 410 can further utilize the aforementioned interlayer space 4101 to buffer the airflow flowing to the intake end of the exhaust assembly 300, and can increase the contact area between the annular rib 410 and the airflow, further enhancing the bubble-breaking effect of the annular rib 410 and reducing the possibility of bubbles accumulating at or entering the intake end of the exhaust assembly 300.

[0077] It is understandable that the cross-sectional area of ​​the interlayer space 4101 perpendicular to the conduction direction of the filter hole 401 is larger than the cross-sectional area of ​​the filter hole 401. Therefore, after the gas flows into the interlayer space 4101 through the end of the filter hole 401 located on the outer peripheral wall of the annular rib 410, it can diffuse to a certain extent within the interlayer space 4101, which can increase the contact area between the gas and the annular rib 410, further extend the gas flow path, and increase the probability of the bubble bursting at the annular rib 410.

[0078] like Figure 2 and Figure 4 As shown, in some examples, the exhaust assembly 300 includes: an exhaust valve 310 disposed on the first cover portion 210; a hanging shaft 320 connected between the exhaust valve 310 and the second cover portion 220, the hanging shaft 320 forming an air passage 3201, the input end of the air passage 3201 being located between the first cover portion 210 and the second cover portion 220, and the output end of the air passage 3201 being connected to the air inlet end of the exhaust valve 310; wherein, an anti-clogging assembly 400 is sleeved on the hanging shaft 320, and a filter hole 401 is connected to the air passage 3201.

[0079] In this technical solution, the aforementioned exhaust assembly 300 may include an exhaust valve 310 and a lifting shaft 320. The exhaust valve 310 is disposed on the aforementioned first cover portion 210. The outlet end of the exhaust valve 310 is used to connect to the external environment. In the open state, the inlet end and outlet end of the exhaust valve 310 are interconnected, and the inlet end can receive gas flowing through the aforementioned filter hole 401. Correspondingly, in the closed state, the inlet end and outlet end of the exhaust valve 310 are cut off. The lifting shaft 320 is connected to the aforementioned exhaust valve 310 and forms a gas passage 3201. The input end of the gas passage 3201 is also the inlet end of the exhaust assembly 300. Correspondingly, the gas passage 3201... The input end is located between the first cover portion 210 and the second cover portion 220, so that the air passage 3201 can be connected to the transition chamber 201 through the filter hole 401 of the anti-blocking component 400. The output end of the air passage 3201 is connected to the air inlet end of the exhaust valve 310 so as to guide the gas to the exhaust valve 310. The aforementioned second cover portion 220 can be connected to the aforementioned hanging shaft 320, thereby improving the installation stability of the second cover portion 220. The aforementioned anti-blocking component 400 can be sleeved on the aforementioned hanging shaft 320 so as to filter the airflow and break the air bubbles carried by the airflow during the exhaust process, reducing the possibility of bubbles accumulating in or entering the air passage 3201.

[0080] It is understandable that in this technical solution, the anti-blocking component 400 and the pot lid component 200 are separate structures.

[0081] like Figure 4 , Figures 6 to 9 As shown, in some examples, the anti-clogging component 400 includes: an anti-clogging cover 430 sleeved on the hanging shaft 320, the anti-clogging cover 430 having filter holes 401, and the air inlet end of the air passage 3201 located inside the anti-clogging cover 430.

[0082] In this technical solution, the aforementioned anti-clogging component 400 may include an anti-clogging cover 430. The anti-clogging cover 430 is sleeved on the aforementioned hanging shaft 320 and has a filter hole 401. The air inlet end of the aforementioned air passage 3201 is located inside the anti-clogging cover 430. Based on the aforementioned configuration, the anti-clogging cover 430 can isolate the transition cavity 201 and the air inlet end of the cooking component to a certain extent. The aforementioned filter hole 401 can connect the inner and outer sides of the anti-clogging cover 430, so that the input end of the air passage 3201 can be connected to the transition cavity 201 through the filter hole 401. This can improve the bubble breaking effect of the anti-clogging cover 430, reduce the possibility of bubbles accumulating in or in the air passage 3201, and the anti-clogging cover 430 and the pot lid assembly 200 can be a separate structure, which facilitates the independent processing and molding of the anti-clogging cover 430 and helps to reduce the processing difficulty of the pot lid assembly 200 and the anti-clogging cover 430.

[0083] It is understandable that, such as Figures 7 to 9As shown, the anti-blocking cover 430 may have an open end and a connecting hole arranged opposite to the open end. In practical applications, the hanging shaft 320 may pass through the aforementioned connecting hole, and the aforementioned open end may abut against the first cover portion 210 and be covered by the first cover portion 210, thereby facilitating the connection of the hanging shaft 320 to the second cover portion 220.

[0084] like Figure 1 , Figure 3 and Figure 5 As shown, in some examples, the air intake end of the exhaust assembly 300 is arranged corresponding to the middle of the second cover portion 220, and the flow hole 2201 is arranged close to the edge of the second cover portion 220; and / or the distance between the air intake end of the exhaust assembly 300 and the flow hole 2201 is greater than or equal to 20 mm.

[0085] In this technical solution, the air inlet of the exhaust assembly 300 can be arranged corresponding to the middle of the second cover portion 220, and the flow hole 2201 can be arranged close to the edge of the second cover portion 220. Based on the aforementioned arrangement, on the one hand, the distance between the air inlet of the exhaust assembly 300 and the flow hole 2201 can be increased, the flow distance of gas in the transition cavity 201 can be extended, and the probability of bubbles naturally bursting in the transition cavity 201 can be increased, which is conducive to further reducing the possibility of bubbles accumulating at or entering the air inlet of the exhaust assembly 300. On the other hand, while ensuring the distance between the air inlet of the exhaust assembly 300 and the flow hole 2201, multiple flow holes 2201 can be arranged circumferentially along the second cover portion 220 to improve the gas passage efficiency between the transition cavity 201 and the cooking cavity 101.

[0086] In this technical solution, the distance between the air inlet end of the exhaust assembly 300 and the flow passage 2201 can be set to be greater than or equal to 20mm, thereby increasing the distance between the air inlet end of the exhaust assembly 300 and the flow passage 2201, extending the flow distance of the gas in the transition chamber 201, increasing the probability of the bubbles naturally bursting in the transition chamber 201, and further reducing the possibility of bubbles accumulating at or entering the air inlet end of the exhaust assembly 300.

[0087] Understandably, in practical applications, the upper limit of the distance between the air inlet end of the exhaust assembly 300 and the flow passage 2201 can be selected based on actual needs or the size parameters of the lid assembly 200, and no further restrictions are imposed here. For example, the distance between the air inlet end of the exhaust assembly 300 and the flow passage 2201 can be set to be greater than or equal to 20mm and less than or equal to 200mm.

[0088] Understandably, in practical applications, the air intake end of the exhaust assembly 300 can be arranged corresponding to the middle of the second cover portion 220, and the flow passage 2201 can be arranged close to the edge of the second cover portion 220, while the distance between the air intake end of the exhaust assembly 300 and the flow passage 2201 can be greater than or equal to 20mm.

[0089] like Figure 2 As shown, in some examples, along the arrangement direction of the cooking cavity 101 and the transition cavity 201, the width H1 of the transition cavity 201 is greater than or equal to 5 mm.

[0090] In this technical solution, the width H1 of the transition cavity 201 can be set to be greater than or equal to 5mm along the arrangement direction of the cooking cavity 101 and the transition cavity 201, thereby improving the fluid passage of the transition cavity 201 and helping to ensure the exhaust efficiency of the pressure cooking appliance.

[0091] It is understood that, in practical applications, the upper limit of the width H1 of the transition cavity 201 along the arrangement direction of the cooking cavity 101 and the transition cavity 201 can be selected based on actual needs or the size parameters of the lid assembly 200, and no further limitations are imposed here. For example, the aforementioned size H1 can be set to be greater than or equal to 5 mm and less than or equal to 100 mm.

[0092] It is understood that the arrangement direction of the aforementioned cooking cavity 101 and transition cavity 201 refers to the arrangement direction when the lid assembly 200 covers the pot opening of the pot body assembly 100. Accordingly, the aforementioned arrangement direction is highly consistent with the height direction of the pressure cooking appliance.

[0093] In some examples, the pressure cooking appliance further includes: a temperature detection component for detecting temperature information within the cooking chamber 101, with at least a portion of the temperature detection component located within the transition chamber 201; and / or an image acquisition component for acquiring image information within the cooking chamber 101, with at least a portion of the image acquisition component located within the transition chamber 201; and / or a float assembly disposed on the lid assembly 200, with at least a portion of the float assembly located within the transition chamber 201.

[0094] In this technical solution, the pressure cooking appliance may also include a temperature detection component for detecting temperature information inside the cooking chamber 101, so as to facilitate the monitoring of the temperature inside the cooking chamber 101 during the cooking process and help ensure the cooking effect. Accordingly, at least part of the temperature detection component can be located inside the transition chamber 201, so that the pressure cooking appliance can further utilize the temperature detection component to contact the airflow inside the transition chamber 201 during the exhaust process, increasing the probability of the bubbles carried by the airflow breaking.

[0095] In this technical solution, the pressure cooking appliance may also include an image acquisition component for acquiring image information inside the cooking chamber 101, thereby facilitating the use of the aforementioned image information to determine the condition of the ingredients inside the cooking chamber 101 during the cooking process, which is beneficial to ensuring the cooking effect. Accordingly, at least part of the image acquisition component can be located inside the transition chamber 201, so that the pressure cooking appliance can further utilize the image acquisition component to contact the airflow inside the transition chamber 201 during the exhaust process, increasing the probability of the bubbles carried by the airflow breaking.

[0096] In this technical solution, the pressure cooking appliance may also include a float assembly disposed on the lid assembly 200. The float assembly is used to restrict the movement of the lid assembly 200 when pressure is applied in the cooking chamber 101, which helps to prevent the lid assembly 200 from opening during cooking and improves the safety of pressure cooking. Accordingly, at least part of the float assembly can be located in the transition chamber 201, so that the pressure cooking appliance can further utilize the float assembly to contact the airflow in the transition chamber 201 during the exhaust process, increasing the probability of the bubbles carried by the airflow breaking.

[0097] It is understandable that, in practical applications, pressure cooking appliances may include at least one of the aforementioned temperature detection components, image acquisition components, and float components.
