Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, and specifically provides a cover assembly and a cooking utensil. Background Art

[0002] Currently, when cooking with a cooking utensil, liquid ingredients such as porridge and thick soup will form bubbles and be discharged from the cooking utensil through the exhaust end of the exhaust component, thereby causing the ingredients to overflow.

[0003] In the related art, in order to solve the problem of food overflow, a bubble breaker is installed at the air inlet end of the exhaust assembly to prevent overflow and break bubbles. However, since the cooking utensils need to meet the volume requirements of the cooking cavity, the space available for the bubble breaker to be installed in the cooking utensils is small, and thus only a smaller bubble breaker can be used for preventing overflow and breaking bubbles. The bubble breaking effect of a smaller bubble breaker is limited, resulting in a poor overall bubble breaking effect of the bubble breaker. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the present invention provides a cover assembly.

[0006] A second aspect of the present invention provides a cooking utensil.

[0007] In view of this, the first aspect of the utility model provides a cover assembly, the cover assembly is used for a cooking utensil, the cooking utensil includes a cooking cavity, and the cover assembly includes: a first cover body, an exhaust assembly, an anti-overflow component and a sealing component. The exhaust assembly is arranged on the first cover body, and the first end of the exhaust assembly faces the cooking cavity; the anti-overflow component has a first through hole and an anti-overflow cavity; the sealing component is arranged in the anti-overflow cavity and sleeved on the exhaust assembly, the sealing component and the inner wall of the anti-overflow cavity enclose a first channel, and the first channel is connected to the first through hole; the sealing component has a second channel, and the first channel is connected to the exhaust assembly through the second channel.

[0008] The cover assembly provided by the utility model is used for a cooking utensil, and the cooking utensil comprises a cooking cavity, and food materials such as porridge and thick soup can be accommodated in the cooking cavity.

[0009] The cover assembly comprises a first cover body, an exhaust assembly, an anti-overflow component and a sealing component. The first cover body can be located at the upper part of the cooking cavity, and the first cover body bears the pressure of the cooking cavity to maintain the pressure of the cooking cavity.

[0010] The exhaust component is arranged on the first cover body, the exhaust component is used for exhausting, and the first end of the exhaust component faces the cooking cavity. The overflow prevention component has a first through hole and an overflow prevention cavity, and the overflow prevention component is used for overflow prevention and bubble breaking. The sealing component is arranged in the overflow prevention cavity and sleeved on the exhaust component, the sealing component and the inner wall of the overflow prevention cavity enclose a first channel, the first channel is connected to the first through hole, and the sealing component has a second channel, and the first channel is connected to the exhaust component through the second channel.

[0011] During the operation of the cooking appliance, the temperature in the cooking cavity rises. Since the cover assembly seals the cooking cavity through the first cover body, the pressure in the cooking cavity rises. The pressure inside the cooking cavity is greater than the gas pressure outside the cooking appliance. At this time, the cooking speed is faster, and the exhaust assembly can be used to guide the air into the cooking cavity to adjust the air pressure in the cooking cavity, thereby enriching the working mode of the cooking appliance and improving the cooking effect.

[0012] When the cooking appliance is venting, the gas pressure in the cooking chamber drops in a short time. Since the temperature of the food in the cooking chamber drops slowly and the boiling point of the liquid decreases, the liquid food will boil in a short time and form bubbles. The bubbles formed by the sudden boiling liquid food can be destroyed by the overflow prevention component and the sealing component, thereby achieving overflow prevention of the exhaust component.

[0013] Specifically, during the exhaust process, bubbles formed by liquid food flow toward the first through hole, and in the process of passing through the first through hole, bubbles with larger diameters among the bubbles formed by the liquid food cannot pass through the first through hole, and are then squeezed and broken, achieving preliminary bubble breaking. In addition, solid food flowing toward the first through hole cannot pass through the first through hole either. The first through hole can screen food materials to prevent foreign matter from clogging the first through hole, the first channel or the second channel. Bubbles with smaller diameters pass through the first through hole into the first channel formed by the sealing component and the inner wall of the anti-overflow cavity, and then flow into the second channel connected to the first channel, and then flow from the second channel to the exhaust component.

[0014] The utility model extends the exhaust path by arranging the first through hole, the first channel and the second channel within the limited space of the cover assembly without increasing the volume of the overflow prevention component. The bubbles need to flow through the first channel and the second channel to reach the exhaust assembly. The movement path of the bubbles formed by the liquid food is longer, which increases the exhaust time and the time for the gas to dissolve in the liquid. The second channel improves the bubble breaking effect, and the longer exhaust path can also prevent the liquid food from directly rushing into the exhaust assembly, ultimately improving the overflow prevention effect, and ensuring that the gas exhausted by the exhaust assembly is pure steam, thus avoiding the overflow phenomenon and making the cooking appliance easy to use.

[0015] In addition, the cover assembly in the above technical solution provided by the utility model may also have the following additional technical features:

[0016] In some technical solutions of the utility model, optionally, the cover assembly further includes a second cover body, which is connected to the first cover body and is located on a side of the first cover body close to the cooking cavity; the sealing component includes: a first body, a first sealing portion, and a second sealing portion. The first body is connected to the second cover body and is sleeved on the exhaust assembly; the first sealing portion extends along the circumference of the exhaust assembly, the inner periphery of the first sealing portion is connected to the first body, and the outer periphery of the first sealing portion abuts against the inner wall of the anti-overflow cavity; the second sealing portion and the first sealing portion are arranged along the axial direction of the exhaust assembly, and the second sealing portion extends along the circumference of the exhaust assembly, the inner periphery of the second sealing portion is connected to the first body, and the outer periphery of the second sealing portion abuts against the inner wall of the anti-overflow cavity; the first body, the first sealing portion, the second sealing portion, and the inner wall of the anti-overflow cavity surround a first channel.

[0017] In this technical solution, the cover assembly also includes a second cover body, which is connected to the first cover body and is located on a side of the first cover body close to the cooking cavity. The cover assembly can be set on the pot assembly and other components of the cooking utensil through the second cover body. The first cover body is set more stably, and the first cover body and the second cover body bear the pressure of the cooking cavity to maintain the pressure of the cooking cavity.

[0018] As for the specific structure of the sealing component, the utility model is configured such that the sealing component includes a first body, a first sealing part, and a second sealing part. The first body, the first sealing part, the second sealing part, and the inner wall of the anti-overflow cavity are surrounded by a first channel, and the first channel is used for the flow of liquid food, thereby extending the flow path of the liquid food, and better realizing the anti-overflow effect. The sealing of the first sealing part and the second sealing part can prevent the liquid food from directly entering the second channel, ensuring that the liquid food can flow from the first channel to the second channel, and stably prevent bubbles from overflowing through the cooperation of the first channel and the second channel.

[0019] In some technical solutions of the present invention, optionally, the sealing component includes: a spoiler, which is arranged at one of the first sealing portion and the second sealing portion and extends toward the other of the first sealing portion and the second sealing portion.

[0020] In this technical solution, the sealing component also includes a spoiler, which is optimized for the flow characteristics of liquid food and effectively realizes the anti-overflow function.

[0021] The spoiler is disposed at one of the first sealing portion and the second sealing portion, and extends toward the other of the first sealing portion and the second sealing portion. The spoiler can effectively guide the flow direction of the liquid food, guide the liquid food to a designated area, and avoid the food from flowing randomly.

[0022] The spoiler further increases the flow path of the liquid food inside the sealing component on the basis of the first channel and the second channel, slows down the flow speed to a certain extent, gives the food more reaction time, eliminates the bubbles in the liquid food, and effectively reduces the possibility of overflow. The purpose is to ensure that the liquid food can flow stably inside the sealing component even under high pressure or high flow, break the bubbles, and prevent the liquid food from overflowing.

[0023] In some technical solutions of the utility model, optionally, the spoiler includes a first spoiler and a second spoiler, the first spoiler is connected to the first sealing portion and extends toward the second sealing portion; the second spoiler is connected to the second sealing portion and extends toward the first sealing portion; wherein, the number of the first spoilers is multiple, the number of the second spoilers is multiple, and the multiple first spoilers and the multiple second spoilers are arranged alternately.

[0024] In this technical solution, the spoiler specifically includes a first spoiler portion and a second spoiler portion, and the number of the first spoiler portions is plural, and the number of the second spoiler portions is plural.

[0025] A plurality of first spoilers are connected to the first sealing portion and extend toward the second sealing portion, and a plurality of second spoilers are connected to the second sealing portion and extend toward the first sealing portion. A plurality of first spoilers and a plurality of second spoilers extend oppositely, and a plurality of first spoilers and a plurality of second spoilers are alternately arranged. When the liquid food flows through the first channel, it will move in a serpentine manner in the curved channel formed by the plurality of first spoilers and the plurality of second spoilers, and the liquid food moves up and down, and the moving path is longer, the probability of bubbles being destroyed is greater, and the gas-liquid dissolution time is longer, which can further improve the anti-overflow effect of the cooking utensil.

[0026] In some technical solutions of the present utility model, optionally, the second channel is provided in the first body and arranged along the radial direction of the exhaust assembly.

[0027] In this technical solution, as to the specific arrangement of the second channel, the utility model is arranged such that the second channel is arranged in the first body and arranged along the radial direction of the exhaust component to meet the flow requirements of the fluid along the radial direction.

[0028] In addition, the first channel and the second channel work together to extend the moving path of the liquid food in the sealing component. Due to the extension of the moving path, the liquid food will encounter more obstacles and turns during the flow, so that its flow rate will naturally slow down. This slowdown helps prevent overflow problems caused by excessive flow rate and makes the probability of bubbles breaking higher, thereby preventing the cooking appliance from overflowing and breaking bubbles.

[0029] In some technical solutions of the present utility model, optionally, there are multiple first through holes, and the multiple first through holes are arranged along the circumference of the first channel.

[0030] In this technical solution, for the first through hole, the utility model is configured such that the number of the first through holes is multiple, and the multiple first through holes are arranged along the circumference of the first channel. The first through hole is configured as a bubble breaking hole for processing bubbles that may be generated in the liquid food.

[0031] The first through hole reduces the size and number of bubbles in the liquid food. A plurality of bubble breaking holes are arranged around the first channel, and bubbles in the fluid are effectively broken when passing through these holes before entering the first channel, thereby improving the anti-overflow bubble breaking effect.

[0032] In some technical solutions of the present invention, optionally, the sealing component and the anti-overflow component are interference fit.

[0033] In this technical solution, the connection between the sealing component and the anti-overflow component adopts an interference fit, thereby ensuring a tight connection and reliable sealing between the two. The interference fit design between the sealing component and the anti-overflow component can effectively prevent the overflow of liquid food, stably extend the flow path of the liquid food, and improve the anti-overflow effect.

[0034] In addition, interference fit can also improve the service life and stability of sealing components and anti-overflow components. Due to the close connection between them, the two components are not easy to move or deform relative to each other when subjected to external forces or pressures, thus reducing the possibility of wear and failure.

[0035] In some technical solutions of the present utility model, optionally, the sealing component and the exhaust assembly are interference fit, and the interference between the sealing component and the exhaust assembly is greater than or equal to 0.2 mm and less than or equal to 3 mm.

[0036] In this technical solution, the connection between the sealing component and the anti-overflow component adopts an interference fit, and under the interference fit, there is a certain amount of interference between the outer periphery of the sealing component and the inner periphery of the anti-overflow component. As for the specific range of the interference, the utility model comprehensively determines the interference within the range of greater than or equal to 0.2 mm and less than or equal to 3 mm based on actual application requirements and factors such as the material and precision of the components.

[0037] The minimum interference of 0.2 mm ensures that there is sufficient preload and friction between the sealing component and the exhaust assembly to achieve a reliable sealing effect. Even under certain pressure and vibration during operation, the two components can remain tightly connected to prevent gas or liquid leakage. The maximum interference of 3 mm avoids assembly difficulties or component damage caused by excessive interference.

[0038] In some technical solutions of the present utility model, optionally, there are multiple first channels, and the multiple first channels are arranged in parallel along the axial direction of the exhaust component.

[0039] In this technical solution, there are multiple first channels, and the multiple first channels are arranged in parallel along the axial direction of the exhaust component to improve the exhaust efficiency.

[0040] In some technical solutions of the present utility model, optionally, the anti-overflow cavity includes a first cavity and a second cavity, the first cavity can be connected to the cooking cavity through a first through hole, the second cavity is connected to the first cavity, and the sealing component is arranged in the second cavity.

[0041] In this technical solution, the anti-overflow cavity is designed to include a first cavity and a second cavity, and the first cavity and the second cavity work together to prevent food from overflowing during the cooking process.

[0042] The first cavity, as a part of the anti-overflow cavity, can be connected with the cooking cavity through the first through hole. The first cavity can promptly receive and contain liquid food overflowing from the cooking cavity.

[0043] The second cavity is connected to the first cavity, which enhances the capacity of the anti-overflow cavity and prolongs the movement path of the liquid food. The liquid food in the first cavity flows into the second cavity, thereby avoiding the risk of overflow caused by excessive food. The existence of the second cavity also provides more buffer space for handling overflowing food.

[0044] The sealing component is arranged in the second cavity to ensure that the second cavity can remain sealed when receiving liquid food, and bubbles are broken in the second cavity to prevent the liquid food from leaking into the exhaust component.

[0045] In some technical solutions of the utility model, optionally, the anti-overflow component includes: a second body, the second body is provided with a first through hole and an anti-overflow cavity; a partition, the partition is arranged in the anti-overflow cavity and connected to the second body, the partition separates the anti-overflow cavity into a first cavity and a second cavity.

[0046] In this technical solution, the overflow prevention component includes a second body and a partition. The second body is the main body of the overflow prevention component, and is provided with a first through hole and an overflow prevention cavity.

[0047] A partition is provided in the anti-overflow cavity. The partition is connected to the second body, and the anti-overflow cavity is divided into a first cavity and a second cavity. The partition design helps to better manage and control the overflowed liquid food. When the food overflows from the cooking cavity, they are blocked by the partition and cannot directly enter the second cavity. They will first flow through the first cavity and then enter the second cavity, which prolongs the flow path of the food, slows down the overflow speed of the food, and provides users with more reaction time to deal with the overflow.

[0048] In addition, the setting of the partition also helps to optimize the overall performance of the overflow prevention component. By adjusting the position and shape of the partition, the flow path and distribution state of the food in the overflow prevention cavity can be further controlled, thereby improving the overflow prevention effect.

[0049] In some technical solutions of the utility model, optionally, the partition is provided with a second through hole, and the first cavity is connected with the second cavity through the second through hole; and / or there is a gap between the partition and the second cover body, and the first cavity is connected with the second cavity through the gap.

[0050] In this technical solution, on the one hand, the partition is provided with a second through hole, and the first cavity is connected to the second cavity through the second through hole. The second through hole on the partition allows the first cavity to be connected to the second cavity. This connection can enable liquid food to flow into the second cavity in a controlled manner under certain conditions, such as when the liquid level in the first cavity reaches a certain height, thereby avoiding excessive overflow of food. At the same time, the design of the second through hole also helps to balance the pressure between the two cavities and prevent accidental leakage caused by pressure difference.

[0051] On the other hand, there is a gap between the partition and the second cover, and the first cavity is connected to the second cavity through the gap. The gap between the partition and the second cover provides another way for the first cavity and the second cavity to communicate. This gap design can allow gas or a small amount of liquid to pass when needed.

[0052] On the other hand, the partition is provided with a second through hole, the first cavity is connected with the second cavity through the second through hole, there is a gap between the partition and the second cover, the first cavity is connected with the second cavity through the gap. The first cavity and the second cavity are connected through the second through hole and the gap, ensuring the effect of connection.

[0053] In summary, the design of the partition, the second through hole thereon, and the gap between the partition and the second cover body provide more functionality and flexibility for the anti-overflow component, enabling it to better adapt to different cooking needs and equipment conditions and effectively prevent the overflow of liquid ingredients.

[0054] In some technical solutions of the present invention, optionally, the second body is provided with a reflux hole, which is connected to the first cavity, and the liquid food in the first cavity can flow back to the cooking cavity through the reflux hole.

[0055] In this technical solution, the utility model further provides a reflux hole on the second body, and the reflux hole is connected with the first cavity. This connectivity enables the liquid food in the first cavity to effectively flow back to the cooking cavity through the reflux hole.

[0056] During the cooking process, especially when liquid ingredients are involved, ingredients may overflow. When the liquid ingredients in the first cavity reach a certain level or meet specific conditions, they will naturally flow back to the cooking cavity through the reflux hole, and the soup, reflux water, food, etc. that enter the first cavity during the cooking process will flow into the cooking cavity, thereby ensuring the effective use of ingredients during the cooking process and further improving the flavor of the ingredients.

[0057] In some technical solutions of the present utility model, optionally, the anti-overflow cavity includes a third cavity, the third cavity can be connected with the cooking cavity through the first through hole, and the sealing component is arranged in the third cavity.

[0058] In this technical solution, the anti-overflow cavity specifically includes a third cavity, which can be connected to the cooking cavity through a first through hole. The first through hole realizes the interaction between the third cavity and the cooking cavity, and liquid food can enter the third cavity through the first through hole.

[0059] The utility model is a single-cavity overflow prevention setting, in which a sealing component is set in the third cavity to prevent liquid food from overflowing. When steam or liquid increases in the cooking cavity, these gaseous or liquid substances will be discharged through the exhaust component, and these substances will first be guided to the third cavity when discharged, rather than being directly discharged to the exhaust component. The sealing component plays an intercepting role in the third cavity. It effectively prevents the passage of liquid food and only allows gas to be discharged through the exhaust component, so that even if a large amount of steam or liquid is generated during the cooking process, it can ensure that the liquid food will not leak out from the exhaust component, thereby keeping the cooking environment clean.

[0060] In addition, by limiting the flow of food in a single cavity, the single cavity structure can further reduce the possibility of liquid food being discharged from the exhaust assembly. This design not only improves the safety of the cooking device, but also optimizes the overall performance of the device.

[0061] A second aspect of the utility model provides a cooking utensil, comprising a cover assembly as in any of the above technical solutions.

[0062] The cooking utensil proposed in the utility model includes a cover assembly as in any of the above technical solutions, and thus has all the beneficial technical effects of the cover assembly as in any of the above technical solutions.

DETAILED DESCRIPTION

[0079] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0080] In the following description, many specific details are set forth to facilitate 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0081] Refer to the following Figures 1 to 12 A lid assembly 100 and a cooking appliance 10 according to some embodiments of the present invention are described.

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the utility model, a cover assembly 100 is provided. The cover assembly 100 is used for a cooking utensil 10. The cooking utensil 10 includes a cooking cavity 200. The cover assembly 100 includes: a first cover body 110, an exhaust assembly 130, an anti-overflow component 140, and a sealing component 170. The exhaust assembly 130 is arranged on the first cover body 110, and the first end of the exhaust assembly 130 faces the cooking cavity 200; the anti-overflow component 140 has a first through hole 142 and an anti-overflow cavity 144; the sealing component 170 is arranged in the anti-overflow cavity 144 and sleeved on the exhaust assembly 130. The sealing component 170 and the inner wall 151 of the anti-overflow cavity 144 enclose a first channel 172, and the first channel 172 is communicated with the first through hole 142; the sealing component 170 has a second channel 174, and the first channel 172 is communicated with the exhaust assembly 130 through the second channel 174.

[0083] In this embodiment, the cover assembly 100 proposed by the utility model is used for a cooking utensil 10, and the cooking utensil 10 includes a cooking cavity 200, in which food materials such as porridge and soup can be placed. The cover assembly 100 includes a first cover body 110, an exhaust assembly 130, an anti-overflow component 140 and a sealing component 170. The first cover body 110 is disposed on the upper part of the cooking cavity 200, and the first cover body 110 bears the pressure of the cooking cavity 200 to maintain the pressure of the cooking cavity 200.

[0084] The exhaust assembly 130 is disposed on the first cover body 110, and the exhaust assembly 130 is used for exhausting, and the first end of the exhaust assembly 130 faces the cooking cavity 200. The anti-overflow component 140 has a first through hole 142 and an anti-overflow cavity 144, and the anti-overflow component 140 is used for anti-overflow and bubble breaking. The sealing component 170 is disposed in the anti-overflow cavity 144 and sleeved on the exhaust assembly 130, and the sealing component 170 and the inner wall 151 of the anti-overflow cavity 144 enclose a first channel 172, and the first channel 172 is communicated with the first through hole 142, and the sealing component 170 has a second channel 174, and the first channel 172 is communicated with the exhaust assembly 130 through the second channel 174.

[0085] During the operation of the cooking appliance 10, the temperature in the cooking cavity 200 rises. Since the cover assembly 100 seals the cooking cavity 200 through the first cover body 110, the pressure in the cooking cavity 200 rises. The pressure inside the cooking cavity 200 is greater than the gas pressure outside the cooking appliance 10. At this time, the cooking speed is faster, and the exhaust assembly 130 can be used to guide the air in the cooking cavity 200 to adjust the air pressure in the cooking cavity 200, thereby enriching the working mode of the cooking appliance 10 and improving the cooking effect.

[0086] When the cooking appliance 10 is venting, the gas pressure in the cooking cavity 200 drops in a short time. Since the temperature of the food in the cooking cavity 200 drops slowly and the boiling point of the liquid decreases, the liquid food will boil in a short time to form bubbles. The bubbles formed by the sudden boiling of the liquid food can be destroyed by the overflow prevention component 140 and the sealing component 170, thereby achieving overflow prevention of the exhaust component 130.

[0087] Specifically, during the exhaust process, bubbles formed by the liquid food flow toward the first through hole 142, and in the process of passing through the first through hole 142, bubbles with larger diameters among the bubbles formed by the liquid food cannot pass through the first through hole 142, and are then squeezed and broken, thereby achieving preliminary bubble breaking. In addition, solid food flowing toward the first through hole 142 is also unable to pass through the first through hole 142. The first through hole 142 can screen the food and prevent foreign matter from clogging the first through hole 142, the first channel 172 or the second channel 174.

[0088] Bubbles with smaller diameters enter the first channel 172 defined by the sealing component 170 and the inner wall 151 of the anti-overflow cavity 144 through the first through hole 142 , then flow into the second channel 174 connected to the first channel 172 , and then flow from the second channel 174 to the exhaust assembly 130 .

[0089] The utility model extends the exhaust path by setting the first through hole 142, the first channel 172 and the second channel 174 within the limited space of the cover assembly 100 without increasing the volume of the overflow prevention component 140. The bubbles need to flow through the first channel 172 and the second channel 174 to reach the exhaust assembly 130. The movement path of the bubbles formed by the liquid food is longer, which increases the exhaust time and the time for the gas to dissolve in the liquid. The second channel 174 improves the bubble breaking effect, and the longer exhaust path can also prevent the liquid food from directly rushing into the exhaust assembly 130, ultimately improving the overflow prevention effect, and ensuring that the gas exhausted from the exhaust assembly 130 is pure steam, thus avoiding overflowing, and making the cooking appliance 10 easy to use.

[0090] Specifically, Figure 1 and Fig. 9 As shown, the cover assembly 100 also includes an anti-blocking component 190, which is arranged on the anti-overflow component 140, located in the anti-overflow cavity 144, and arranged on the peripheral side of the air inlet end of the exhaust assembly 130, thereby preventing the exhaust assembly 130 from being blocked.

[0094] In this embodiment, the cover assembly 100 also includes a second cover body 120, which is connected to the first cover body 110 and is located on a side of the first cover body 110 close to the cooking cavity 200. The second cover body 120 can be used to set the cover assembly on components such as the pot assembly of the cooking utensil 10, so that the first cover body 110 is more stably set to maintain pressure in the cooking cavity 200.

[0095] Specifically, the cooking device 10 includes a pot assembly, which is provided with a pot body, and the pot body is provided with the above-mentioned cooking cavity 200. When set, the second cover body 120 is tightly fitted with the open end of the pot body, and the first cover body 110 is located above the pot body and the second cover body 120. The second cover body 120 and the first cover body 110 cooperate to bear the pressure of the cooking cavity 200 and maintain the pressure of the cooking cavity 200.

[0096] As for the specific structure of the sealing component 170, the utility model is set as follows: the sealing component 170 includes a first body 178, a first sealing portion 180 and a second sealing portion 182, wherein the first body 178 is connected to the second cover 120 and is sleeved on the exhaust assembly 130, thereby realizing that the seal is set on the second cover 120 and the exhaust assembly 130 is connected to the sealing component 170. The first body 178 plays a role in supporting and connecting other components in the entire sealing component 170.

[0097] The first sealing portion 180 extends along the circumference of the exhaust assembly 130 ( Fig. 9The first sealing portion 180 extends in the direction indicated by the middle arrow D), the inner periphery of the first sealing portion 180 is connected to the first body 178, and the outer periphery of the first sealing portion 180 is against the inner wall 151 of the anti-overflow cavity 144. The first sealing portion 180 forms a sealing layer between the exhaust component 130 and the anti-overflow cavity 144 to prevent liquid food from leaking from the gap between the two.

[0098] Specifically, the first sealing portion 180 is a sealing ring.

[0099] The second sealing portion 182 and the first sealing portion 180 are located in the axial direction of the exhaust assembly 130 ( Fig. 9 The second sealing portion 182 is arranged along the circumferential direction of the exhaust assembly 130 ( Fig. 9 The second sealing portion 182 extends in the direction indicated by the middle arrow D, the inner periphery of the second sealing portion 182 is connected to the first body 178, the outer periphery of the second sealing portion 182 abuts against the inner wall 151 of the anti-overflow cavity 144, and the second sealing portion 182 and the first sealing portion 180 cooperate to achieve sealing at different positions along the circumference of the exhaust component 130.

[0100] Specifically, the second sealing portion 182 and the first sealing portion 180 seal the valve core portion of the exhaust assembly 130 .

[0101] The first body 178, the first sealing portion 180, the second sealing portion 182 and the inner wall 151 of the anti-overflow cavity 144 form a first channel 172. The first channel 172 is for liquid food to flow, thereby extending the flow path of the liquid food and better achieving the anti-overflow effect. The sealing of the first sealing portion 180 and the second sealing portion 182 can prevent the liquid food from directly entering the second channel 174, thereby ensuring the anti-overflow effect.

[0102] Specifically, Fig. 9 and Fig.10 As shown, the sealing component 170 further includes a first connecting member 181, which is arranged along the circumference of the first body 178. The first connecting member 181 and the first sealing portion 180 cooperate to form a connecting groove on the first body 178, and the second cover 120 can be inserted into the connecting groove to achieve the connection between the second cover 120 and the first body 178. The sealing component 170 is limited as a whole and is not easy to be displaced relative to the exhaust component 130, so that the exhaust component 130 can be better sealed. Specifically, the first connecting member 181 is a sealing ring.

[0103] Specifically, the second sealing portion 182 is a sealing ring.

[0104] Specifically, the inner periphery of the first sealing part 180 is connected to the first body 178, and the outer periphery of the first sealing part 180 is against the inner wall 151 of the anti-overflow cavity 144. The inner periphery of the second sealing part 182 is connected to the first body 178, and the outer periphery of the second sealing part 182 is against the inside of the anti-overflow cavity 144. Through the cooperation of the first sealing part 180, the first body 178, and the second sealing part 182 with the anti-overflow cavity 144, a first channel 172 is surrounded in the anti-overflow cavity 144, and this channel has a unique air inlet, namely the second channel 174, so as to improve the stability of the bubble breaking and overflow prevention of liquid food. Further, the second cover body 120 is detachably mounted on the first cover body 110, or the second cover body 120 is non-detachably mounted on the first cover body 110.

[0105] The cover assembly 100 may include a face cover and a steel cover. The face cover may be a plastic cover or a metal cover. The steel cover is non-detachably mounted on the face cover. The face cover is the first cover body 110 mentioned in this application, and the steel cover is the second cover body mentioned in this application.

[0106] The cover assembly 100 may also include a face cover, a steel cover and a cover plate. The face cover may be a plastic cover. The steel cover is fixedly mounted on the face cover. The cover plate is detachably mounted on the steel cover. The face cover and / or the steel cover is the first cover body 110 mentioned in this application. The cover plate is the second cover body 120 mentioned in this application.

[0107] The cover assembly 100 may also include a face cover, an inner cover and a steel cover. The face cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the face cover, and the steel cover is non-detachably mounted on the inner cover. The face cover and / or the inner cover are the first cover body 110 mentioned in the present application, and the steel cover is the second cover body mentioned in the present application.

[0108] The cover assembly 100 may also include a face cover, an inner cover, a steel cover and a cover plate. The face cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the face cover, the steel cover is non-detachably mounted on the inner cover, and the cover plate is detachably mounted on the inner cover. The face cover, the inner cover and / or the steel cover are the first cover body 110 mentioned in the present application, and the cover plate is the second cover body 120 mentioned in the present application.

[0109] The cover assembly 100 may also include a face cover, an inner cover, a lock and a cover plate. The face cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the face cover, the lock is non-detachably mounted on the inner cover, and the cover plate is detachably mounted on the inner cover.

[0111] like Fig.10As shown, in some embodiments of the present invention, optionally, the sealing component 170 includes: a spoiler 184, which is disposed at one of the first sealing portion 180 and the second sealing portion 182 and extends toward the other of the first sealing portion 180 and the second sealing portion 182.

[0112] In this embodiment, in the sealing component 170, in addition to the first body 178, the first sealing portion 180 and the second sealing portion 182, the sealing component 170 further includes a spoiler 184. The spoiler 184 guides the flow of the liquid food according to the flow characteristics of the liquid food, thereby effectively realizing the anti-overflow function.

[0113] The spoiler 184 is disposed on one of the first sealing portion 180 and the second sealing portion 182, and extends toward the other of the first sealing portion 180 and the second sealing portion 182. Specifically, on one hand, the spoiler 184 is disposed on the first sealing portion 180, and the spoiler 184 extends toward the second sealing portion 182. On the other hand, the spoiler 184 is disposed on the second sealing portion 182, and the spoiler 184 extends toward the second sealing portion 182. The spoiler 184 can effectively guide the flow direction of the liquid food. The liquid food is guided to a designated area, and the food is prevented from flowing randomly.

[0114] The presence of the spoiler 184 further increases the flow path of the liquid food inside the sealing component 170, slows down the flow speed of the liquid food to a certain extent, gives the liquid food more reaction time, eliminates bubbles in the liquid food, and effectively reduces the possibility of overflow. Even under high pressure or high flow conditions, the spoiler 184 can ensure that the liquid food flows stably inside the sealing component 170 without easily overflowing.

[0115] Specifically, the spoiler 184 is a spoiler rib.

[0116] Specifically, on one hand, the spoiler 184 is disposed on the first sealing portion 180 , and the spoiler 184 and the first sealing portion 180 are an integrated structure, and the structural stability between the spoiler 184 and the first sealing portion 180 is higher.

[0117] On the other hand, the spoiler 184 is disposed on the second sealing portion 182 , and the spoiler 184 and the second sealing portion 182 are an integrated structure, and the structural stability between the spoiler 184 and the second sealing portion 182 is higher.

[0118] like Fig.11As shown, in some embodiments of the present invention, optionally, the spoiler 184 includes: a first spoiler 186 and a second spoiler 188, the first spoiler 186 is connected to the first sealing portion 180 and extends toward the second sealing portion 182; the second spoiler 188 is connected to the second sealing portion 182 and extends toward the first sealing portion 180; wherein, the number of the first spoiler 186 is multiple, the number of the second spoiler 188 is multiple, and the multiple first spoilers 186 and the multiple second spoilers 188 are arranged alternately.

[0119] In this embodiment, the spoiler 184 specifically includes a first spoiler 186 and a second spoiler 188, and the number of the first spoiler 186 is multiple, and the number of the second spoiler 188 is multiple. Among them, the multiple first spoilers 186 are connected to the first sealing portion 180 and extend toward the second sealing portion 182, the multiple second spoilers 188 are connected to the second sealing portion 182 and extend toward the first sealing portion 180, the multiple first spoilers 186 and the multiple second spoilers 188 extend oppositely, and the multiple first spoilers 186 and the multiple second spoilers 188 are alternately arranged.

[0120] like Fig.11 As shown, when the liquid food flows through the first channel 172, it will move in a serpentine manner along the path shown by line A in the curved channel formed by the multiple first spoilers 186 and the multiple second spoilers 188. The movement path of the liquid food is longer, the probability of bubbles being destroyed is greater, and the dissolution time is longer, which can further improve the anti-overflow effect of the cooking utensil 10.

[0121] like Figure 2 As shown, in some embodiments of the present invention, optionally, the second channel 174 is disposed on the first body 178 and arranged along the radial direction of the exhaust assembly 130 .

[0122] In this embodiment, regarding the specific arrangement of the second channel 174, the utility model is arranged that the second channel 174 is arranged in the first body 178, along the radial direction ( Fig. 9 It is arranged in the direction indicated by the arrow C.

[0123] The second channel 174 meets the flow requirements of the fluid along the radial direction. In addition, the first channel 172 and the second channel 174 work together to significantly extend the movement path of the liquid food in the sealing component 170. Due to the extension of the path, the liquid food will encounter more obstacles and turns during the flow, thereby naturally slowing down its flow rate. This slowdown helps to prevent overflow problems caused by excessive flow rate, and also makes it possible to destroy a large number of bubbles in the liquid food.

[0124] like Figure 2As shown, in some embodiments of the present invention, optionally, there are multiple first through holes 142 , and the multiple first through holes 142 are arranged along the circumference of the first channel 172 .

[0125] In this embodiment, the utility model provides a plurality of first through holes 142, and the plurality of first through holes 142 are arranged along the circumference of the first channel 172. The first through holes 142 are configured as bubble breaking holes for processing bubbles that may be generated in liquid food.

[0126] The first through hole 142 reduces the size and number of bubbles in the liquid food. By arranging a plurality of bubble breaking holes around the first channel 172, the bubbles in the fluid will be effectively broken when passing through these holes and then enter the first channel 172, thereby improving the anti-overflow bubble breaking effect.

[0127] Specifically, the first through hole 142 is disposed on a side wall of the first body 178 .

[0128] Specifically, the first through hole 142 is a circular hole, an elliptical hole, a polygonal hole or a star-shaped hole.

[0129] When the cooking utensil 10 is venting, food bubbles will overflow with the steam, and some solid food will also overflow under the action of the pressure difference and steam. By setting the shape of the first through hole 142, the overflowing food bubbles can be destroyed, and the solid food can also be blocked, which can reduce the probability of food overflow and prevent solid food from entering the exhaust component 130 through the anti-overflow component 140, thereby reducing the probability of the exhaust component 130 being blocked due to the accumulation of solid food, thereby improving the anti-overflow effect of the cooking utensil 10 and the reliability of the cooking utensil 10. At the same time, the circular hole, elliptical hole, polygonal hole or star-shaped hole can play a role in aesthetics and convenience of stamping, thereby improving the processing and production efficiency of the anti-overflow component 140.

[0130] In some embodiments of the present invention, optionally, the sealing component 170 and the anti-overflow component 140 are interference fit.

[0131] In this embodiment, the connection between the sealing component 170 and the anti-overflow component 140 adopts interference fit. Interference fit means that the external dimensions of one component are designed to be slightly larger than the internal dimensions of the other component, so that the two need to apply a certain pressure or use methods such as thermal expansion and contraction to achieve a tight fit during assembly.

[0132] In the interference fit mode, there is a certain amount of interference between the outer periphery of the sealing component 170 and the inner periphery of the anti-overflow component 140. When the two components are assembled together, due to the existence of the interference, a certain preload and friction force will be generated between them, thereby ensuring a tight connection and reliable sealing between the two.

[0133] The interference fit design between the sealing component 170 and the anti-overflow component 140 can effectively prevent the overflow of liquid food, and can stably extend the flow path of the liquid food, thereby improving the anti-overflow effect.

[0134] In addition, the interference fit can also improve the service life and stability of the sealing component 170 and the anti-overflow component 140. Due to the tight connection between them, the two components are not prone to relative movement or deformation when subjected to external force or pressure, thereby reducing the possibility of wear and failure.

[0135] In some embodiments of the present invention, optionally, the sealing component 170 and the exhaust assembly 130 are interference fit, and the interference between the sealing component 170 and the exhaust assembly 130 is greater than or equal to 0.2 mm and less than or equal to 3 mm.

[0136] In this embodiment, the connection between the sealing component and the anti-overflow component 140 adopts an interference fit, and under the interference fit, there is a certain interference amount between the outer periphery of the sealing component 170 and the inner periphery of the anti-overflow component 140. As for the specific range of the interference amount, the utility model comprehensively determines the interference amount to be greater than or equal to 0.2 mm and less than or equal to 3 mm based on actual application requirements and factors such as the material and precision of the components.

[0137] The minimum interference of 0.2 mm ensures that sufficient preload and friction can be generated between the sealing component 170 and the exhaust assembly 130 to achieve a reliable sealing effect. Even if subjected to certain pressure and vibration during operation, the two components can remain tightly connected to prevent gas or liquid leakage. The maximum interference of 3 mm avoids assembly difficulties or component damage caused by excessive interference.

[0138] Specifically, the interference between the sealing component 170 and the exhaust assembly 130 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm, etc.

[0139] In some embodiments of the present invention, optionally, there are multiple first channels 172 , and the multiple first channels 172 are arranged in parallel along the axial direction of the exhaust assembly 130 .

[0140] like Fig.11 As shown, in this embodiment, there are multiple first channels 172, and the multiple first channels 172 are arranged in parallel along the axial direction of the exhaust component 130, which improves the exhaust speed and also improves the anti-overflow effect.

[0141] Specifically, the plurality of first channels 172 may be arranged in multiple layers.

[0142] Specifically, the plurality of first channels 172 may be arranged in parallel or in a spiral arrangement.

[0143] Specifically, when connected, the first through hole 142 can be connected to the first channel 172 located on the upper side. The gas passes through the first through hole 142, the first channel 172 located on the upper side and the first channel 172 located on the lower side in sequence, enters the second channel 174, and is then discharged by the exhaust assembly 130. The gas movement path is longer, and the cooking utensil 10 has a better anti-overflow and bubble-breaking effect.

[0144] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the anti-overflow cavity 144 includes a first cavity 146 and a second cavity 148. The first cavity 146 can be connected to the cooking cavity 200 through the first through hole 142, and the second cavity 148 is connected to the first cavity 146. The sealing component 170 is disposed in the second cavity 148.

[0145] In this embodiment, the anti-overflow cavity 144 is designed to include a first cavity 146 and a second cavity 148 , and the two cavities work together to prevent the overflow of food during the cooking process.

[0146] The first cavity 146 , as a part of the anti-overflow cavity 144 , can be connected to the cooking cavity 200 through the first through hole 142 . The first cavity 146 can promptly receive and contain liquid food overflowing from the cooking cavity 200 .

[0147] The second cavity 148 is connected to the first cavity 146. This design further enhances the capacity of the overflow prevention cavity 144 and prolongs the moving path of the liquid food. The liquid food in the first cavity 146 flows into the second cavity 148, thereby avoiding the risk of overflow caused by excessive food. The existence of the second cavity 148 also provides more buffer space for handling overflowing food.

[0148] The sealing component 170 is disposed in the second cavity 148 to ensure that the second cavity 148 can remain sealed when receiving liquid food, thereby preventing the food from further leaking into the exhaust assembly 130 .

[0149] like Figure 1 As shown, in some embodiments of the present invention, optionally, the anti-overflow component 140 includes: a second body 150, the second body 150 is provided with a first through hole 142 and an anti-overflow cavity 144; a partition 152, the partition 152 is arranged in the anti-overflow cavity 144 and connected to the second body 150, and the partition 152 separates the anti-overflow cavity 144 into a first cavity 146 and a second cavity 148.

[0150] In this embodiment, the overflow prevention component 140 is composed of a second body 150 and a partition 152. The second body 150 is the main body of the overflow prevention component 140, and is provided with a first through hole 142 and an overflow prevention cavity 144. The first through hole 142 is a passage for the overflow prevention component 140 to communicate with the cooking cavity 200 or other related components, and the overflow prevention cavity 144 is a space for accommodating liquid food that may overflow, thereby preventing these food from directly overflowing into the exhaust assembly 130.

[0151] A partition 152 is provided in the overflow prevention chamber 144. The partition 152 is connected to the second body 150, and divides the overflow prevention chamber 144 into a first cavity 146 and a second cavity 148. This partition design helps to better manage and control the overflowed liquid food.

[0152] When food overflows from the cooking cavity 200, the food is blocked by the partition 152 and cannot directly enter the second cavity 148. It will first flow through the first cavity 146 and then enter the second cavity 148. This design prolongs the flow path of the food, slows down the overflow speed of the food, and provides the user with more reaction time to deal with the overflow.

[0153] In addition, the provision of the partition 152 also helps to optimize the overall performance of the overflow prevention component 140. By adjusting the position and shape of the partition 152, the flow path and distribution state of the food in the overflow prevention cavity 144 can be further controlled, thereby improving the overflow prevention effect.

[0154] Specifically, the second cavity 148 is located below the exhaust assembly 130 .

[0155] like Figure 8 As shown, in some embodiments of the present invention, optionally, the partition 152 is provided with a second through hole 154, and the first cavity 146 is connected to the second cavity 148 through the second through hole 154; and / or there is a gap between the partition 152 and the second cover body 120, and the first cavity 146 is connected to the second cavity 148 through the gap.

[0156] In this embodiment, on the one hand, the partition 152 is provided with a second through hole 154, and the first cavity 146 is connected to the second cavity 148 through the second through hole 154. The second through hole 154 on the partition 152 enables limited communication between the first cavity 146 and the second cavity 148. This connectivity can enable liquid food to flow into the second cavity 148 in a controlled manner under certain conditions, such as when the liquid level in the first cavity 146 reaches a certain height, thereby avoiding excessive overflow of food. At the same time, the design of the second through hole 154 also helps to balance the pressure between the two cavities and prevent accidental leakage caused by the pressure difference.

[0157] On the other hand, there is a gap between the partition 152 and the second cover 120, and the first cavity 146 is connected to the second cavity 148 through the gap. The gap between the partition 152 and the second cover 120 provides another way of communication between the first cavity 146 and the second cavity 148. This gap design allows gas or a small amount of liquid to pass through when necessary, thereby maintaining the balance of airflow and liquid level between the two cavities and avoiding the overflow of food. At the same time, the existence of the gap also helps to reduce component deformation and stress concentration caused by physical phenomena such as thermal expansion and contraction, thereby improving the durability and reliability of the anti-overflow component 140.

[0158] On the other hand, the partition 152 is provided with a second through hole 154, and the first cavity 146 is connected to the second cavity 148 through the second through hole 154. There is a gap between the partition 152 and the second cover 120, and the first cavity 146 is connected to the second cavity 148 through the gap. The first cavity 146 and the second cavity 148 are connected through the second through hole 154 and the gap to ensure the effect of connection.

[0159] In summary, the design of the partition 152 and the second through hole 154 thereon and the gap between the partition 152 and the second cover body 120 provides more functionality and flexibility for the anti-overflow component 140, so that it can better adapt to different cooking needs and equipment conditions and effectively prevent the overflow of liquid ingredients.

[0160] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments of the present invention, optionally, the second body 150 is provided with a reflux hole 158 , which is connected to the first cavity 146 , and the liquid food in the first cavity 146 can flow back to the cooking cavity 200 through the reflux hole 158 .

[0161] In this embodiment, the utility model further provides a reflux hole 158 on the second body 150 , and the reflux hole 158 is connected to the first cavity 146 . This connectivity enables the liquid food in the first cavity 146 to effectively reflux to the cooking cavity 200 through the reflux hole 158 .

[0162] During the cooking process, especially when liquid ingredients are involved, the ingredients may overflow. When the liquid ingredients in the first cavity 146 reach a certain level or meet certain conditions, they will naturally flow back to the cooking cavity 200 through the reflux holes 158, and the soup, reflux water, food, etc. that enter the first cavity 146 during the cooking process will flow into the cooking cavity 200, thereby ensuring the effective use of the ingredients during the cooking process.

[0163] Specifically, the bottom wall 156 of the second body 150 is provided with the reflux hole 158 to ensure that the liquid food can reflux smoothly.

[0164] like Figure 7 As shown, in some embodiments of the present invention, optionally, the anti-overflow cavity 144 includes a third cavity 160 , the third cavity 160 can be connected to the cooking cavity 200 through the first through hole 142 , and the sealing component 170 is disposed in the third cavity 160 .

[0165] In this embodiment, the anti-overflow cavity 144 specifically includes a third cavity 160, which can be connected to the cooking cavity 200 through the first through hole 142. The first through hole 142 realizes the interaction between the third cavity 160 and the cooking cavity 200, and liquid food can enter the third cavity 160 through the first through hole 142.

[0166] The utility model is a single-cavity overflow prevention setting, and the sealing component 170 is arranged in the third cavity 160 to prevent liquid food from overflowing. When steam or liquid increases in the cooking cavity 200, these substances will first be guided to the third cavity 160 through the third cavity 160 and the sealing component 170, rather than being directly discharged to the exhaust component 130.

[0167] The sealing component 170 plays a blocking role in the third cavity 160. It can effectively prevent the passage of liquid food and only allow gas to be discharged through the exhaust component 130. In this way, even if a large amount of steam or liquid is generated during the cooking process, it can ensure that the liquid food will not leak out from the exhaust component 130, thereby maintaining the cleanliness of the cooking environment and the integrity of the food.

[0168] In addition, by limiting the flow of food in a single cavity, the single cavity structure can further reduce the possibility of liquid food being discharged from the exhaust assembly 130.
