Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to an exhaust cover and a container cover. Background Art

[0002] A pot lid is usually composed of a lid body and a lid head. During use, the user can close the pot lid on the pot body or remove the pot lid from the pot body through the lid head. Therefore, the existing lid head only has the function of taking and placing the pot lid, and neither the lid body nor the lid head is provided with exhaust holes, so that after the pot lid is closed on the pot body, the inner cavity of the pot body is in a sealed state. During the process of heating the pot body, the food in the pot body gradually begins to boil as the temperature rises, but since the lid body and the lid head cannot vent, the food is easy to boil and overflow during the cooking process. Utility Model Content

[0003] In view of this, the present application provides a venting cover and a container cover to solve the technical problem in the prior art that the cover body and the cover are unable to vent, causing the food to easily boil over during the cooking process.

[0004] The first aspect of the present application provides an exhaust cover, which includes a main body and an operating member, the main body has an exhaust channel, and the operating member is rotatably connected to the main body through a rotating shaft; wherein the operating member includes a first blocking portion and an operating portion, the rotating shaft is located between the first blocking portion and the operating portion, and when the operating portion is pressed, the operating member can rotate relative to the main body to enable the first blocking portion to open the exhaust channel.

[0005] In the embodiment of the present application, the first blocking portion and the operating portion are respectively arranged at the two ends of the operating member along the second direction y. When the main body and the operating member are connected by the rotation shaft, the user can press the operating portion to make the operating portion move downward along the first direction x, and the operating member rotates around the rotation shaft, thereby driving the first blocking portion to move upward along the first direction x, thereby opening the exhaust channel. At this time, the exhaust cover is in an exhaust state. When the user cancels the pressing of the operating portion, the operating portion moves upward along the first direction x, and the operating member rotates around the rotation shaft, thereby driving the first blocking portion to move downward along the first direction x, thereby blocking the exhaust channel. At this time, the exhaust cover is in a sealed state. Therefore, the exhaust cover provided by the present application not only facilitates the user to take the container cover, but also has the functions of exhaust and sealing, so that the user can timely relieve pressure in the container body during the cooking process to prevent boiling food from overflowing, thereby improving safety during cooking.

[0006] In a possible implementation manner, the exhaust cover head further includes an elastic member, and two ends of the elastic member are respectively connected to the operating portion and the body.

[0007] In the embodiment of the present application, when the user presses the operating part, the operating part can move downward along the first direction x, and in the process of downward movement, the operating part and the main body apply pressure to the elastic member to cause the elastic member to elastically deform, and in the process of downward movement of the operating part, the operating member is driven to rotate around the rotating shaft. During the rotation process, the operating member drives the first blocking part to move upward along the first direction x, thereby opening the exhaust channel. At this time, the exhaust cover is in the exhaust state; when the user cancels the pressing force applied to the operating part, the elastic member releases the rebound force, and under the action of the rebound force of the elastic member, the operating part moves upward along the first direction x, causing the operating member to rotate around the rotating shaft. During the rotation process, the operating member drives the first blocking part to move downward along the first direction x, thereby blocking the exhaust channel. At this time, the exhaust cover is in a sealed state.

[0008] Therefore, the elastic member in the present embodiment will store rebound force when being squeezed. When the user no longer presses the operating part, the pressure on the elastic member will disappear and the elastic member will be able to recover its deformation, thereby driving the operating part and the first blocking part to automatically reset through the rebound force of the elastic member. There is no need to manually control the reset of the above-mentioned components, which simplifies the operating steps. At the same time, when the operating part rotates downward along the first direction x, the elastic member can prevent the operating part from colliding violently with the main body, thereby protecting the internal structure of the exhaust cover head and improving the service life of the exhaust cover head.

[0009] In a possible embodiment, the operating part has a mating surface connected to the elastic part, and the mating surface is inclined downward along the height direction of the exhaust cover head; the main body has a mounting groove, at least part of the elastic part is located in the mounting groove, and when the first blocking part opens the exhaust channel, the mating surface blocks the elastic part in the mounting groove.

[0010] In the embodiment of the present application, the main body is provided with a mounting groove for mounting the elastic member, which is used to limit the movement of the elastic member along the second direction y and the third direction z, so that the possibility of the occurrence of the phenomenon such as dislocation of the elastic member when being squeezed is reduced, and the user's experience when pressing is improved. When the elastic member is installed in the mounting groove, at least part of the elastic member can extend out of the mounting groove along the first direction x and connect with the matching surface of the operating part, and when the user presses the operating part to put the exhaust cover in the exhaust state, the operating part squeezes the elastic member through the matching surface and seals the elastic member in the mounting groove. At this time, the steam in the container body flows out to the external environment through the exhaust channel, and the matching surface can prevent part of the steam from flowing into the mounting groove, thereby reducing the possibility of the elastic member being corroded by moisture, which is conducive to improving the service life of the elastic member. At the same time, the matching surface is a plane inclined downward along the first direction x, so that it can fit with the surface of the mounting groove when the exhaust cover is exhausted, thereby improving the sealing effect, which is conducive to further reducing the possibility of steam flowing into the mounting groove.

[0011] In a possible embodiment, the operating member further includes a rotating portion connected to the first blocking portion and the operating portion, the rotating portion is rotationally connected to the main body via the rotating shaft, and the rotating portion has an arc surface, and when the operating member rotates relative to the main body, the arc surface abuts against the main body.

[0012] In the embodiment of the present application, after the operating member and the main body are rotatably connected by the rotating shaft, the rotating part of the operating member abuts against the main body, and the surface where the rotating part of the operating member abuts against the main body is an arc surface, which is beneficial to improve the smoothness of the user when driving the operating member to rotate, and reduce the possibility of wear between the two during relative movement, thereby increasing the service life of the operating member and the main body. At the same time, the rotating part with an arc surface makes it easier for the user to save effort and drive, so that the operating member can be easily rotated around the rotating shaft relative to the main body, thereby realizing the free conversion of the exhaust cover between the sealing state and the exhaust state, thereby improving the user experience.

[0013] In a possible embodiment, the main body has a accommodating cavity, the first blocking portion is located in the accommodating cavity, the exhaust cover head also includes an isolation portion connected to the main body and the operating member, the isolation portion divides the accommodating cavity into a first cavity and a second cavity, at least part of the structure of the first blocking portion is located in the first cavity, and at least part of the structure of the operating portion is located in the second cavity.

[0014] In the embodiment of the present application, after the exhaust cover is assembled, the isolation part divides the accommodating cavity into a first cavity and a second cavity. Specifically, the first blocking part and the exhaust channel are located in the first cavity, and the operating part, the elastic part and the mounting groove are located in the second cavity, wherein the first cavity and the second cavity are not connected. When the exhaust cover is in the exhaust state, the first blocking part in the first cavity opens the exhaust channel, and the steam in the container body flows into the first cavity through the exhaust channel. At this time, the isolation part can block the steam in the first cavity, reduce the possibility of steam flowing into the second cavity, improve the protection effect of the elastic part, and reduce the risk of the elastic part being affected by moisture and corroded. At the same time, when the exhaust cover is in the sealed state, the isolation part and the operating part can improve the sealing of the first cavity to reduce the possibility of steam leaking from the first cavity to the external environment, thereby helping to improve cooking efficiency.

[0015] In a possible embodiment, the exhaust cover also includes a second blocking portion located in the second cavity, and the side wall of the second cavity is provided with a groove, and the operating member also includes a limiting portion extending outward relative to the operating portion, and when the first blocking portion opens the exhaust channel, the second blocking portion is fitted with the main body to separate the second cavity from the external environment, and the limiting portion abuts against the bottom wall of the groove.

[0016] In the embodiment of the present application, the second blocking portion extends downward along the first direction x relative to the operating portion, and the limiting portion extends along the second direction y relative to the operating portion in a direction away from the first blocking portion. When the user presses the operating portion to make it move downward along the first direction x, the mating surface can squeeze the elastic part and retract it into the installation groove. The second blocking portion and the limiting portion move downward along the first direction x synchronously with the operating portion. When the mating surface is in contact with the upper end surface of the installation groove, the second blocking portion abuts against the main body to block the second cavity and reduce the possibility of steam leaking into the second cavity flowing out to the external environment through the groove, thereby reducing the risk of scalding the user. The limiting portion abuts against the bottom wall of the groove to further block the second cavity, improve the sealing effect of the second cavity, and at the same time limit the travel of the operating part to ensure that after the user removes the external force pressing the operating part, the operating part can be reset under the action of the elastic part, thereby improving the user experience.

[0017] In a possible implementation manner, the operating member has a third blocking portion, and when the first blocking portion blocks the exhaust passage, the third blocking portion blocks the first cavity.

[0018] In the embodiment of the present application, the third sealing portion extends relative to the first sealing portion along the second direction y in a direction away from the operating portion. When the exhaust cover is in a sealed state, the first sealing portion blocks the exhaust passage, and the third sealing portion abuts against the inner wall of the first cavity to seal the first cavity, thereby improving the sealing of the first cavity, thereby further reducing the possibility of air leakage from the exhaust cover in a sealed state during the cooking process, so as to ensure that the food can be cooked under a high temperature and high pressure environment, which is beneficial to improving cooking efficiency. At the same time, the third sealing portion can also prevent external impurities from flowing into the first cavity, thereby reducing the possibility of external impurities flowing into the interior of the container body through the exhaust passage when the exhaust cover is in the exhaust state, thereby reducing the risk of food contamination.

[0019] In a possible embodiment, the operating member also includes a main body, the first blocking part, the rotating part and the operating part are all connected to the main body, the main body has a accommodating cavity and an opening, and when the first blocking part blocks the exhaust channel, the main body blocks the opening, and the upper end surface of the main body is flush with the upper end surface of the main body.

[0020] In the embodiment of the present application, the first blocking part, the rotating part and the operating part are all connected to the main body to improve the structural stability of the operating part as a whole, so that the operating part has good stability and reliability during operation. The main body has a receiving cavity and an opening connected to the receiving cavity, at least part of the operating part is located in the receiving cavity, when the first blocking part blocks the exhaust passage, the main body of the operating part blocks the opening, so that when the first blocking part fails, the main body can block the steam in the receiving cavity, reducing the possibility of steam leakage, thereby further enhancing the sealing performance of the exhaust cover, which is conducive to improving the cooking efficiency of the user, and at the same time, when the exhaust cover is in a sealed state, the upper end surface of the main body is flush with the upper end surface of the main body, which can facilitate the user to distinguish the working state of the exhaust cover, improve the identification effect, and avoid the user from touching the exhaust cover when it is in the exhaust state, thereby reducing the risk of scalding the user and improving the user's experience.

[0021] In a possible implementation, the first blocking portion has a first inclined surface, the main body has a second inclined surface, the exhaust passage extends from the second inclined surface in a direction away from the operating member, and when the first inclined surface is in contact with the second inclined surface, the first blocking portion blocks the exhaust passage.

[0022] In the implementation manner of the present application, when the two surfaces that cooperate with the first sealing part and the main body are both inclined surfaces, they have a good guiding effect, which is convenient for the operating part to rotate and improves the tightness of the cooperation between the first sealing part and the main body. At the same time, when the first inclined surface and the second inclined surface cooperate with each other, the connection area between the first sealing part and the main body is larger, which is beneficial to improve the stability and reliability of the connection between the two, thereby improving the sealing effect of the first sealing part on the exhaust channel and further reducing the possibility of steam leakage.

[0023] A second aspect of the present application provides a container cover, comprising a cover body and an exhaust cover head, wherein the cover body is provided with a mounting hole, and the exhaust cover head is the exhaust cover head described above; wherein the exhaust cover head is mounted in the mounting hole.

[0024] In the embodiment of the present application, when the container lid is closed on the container body, during the cooking process, the exhaust cover in a sealed state will increase the pressure inside the container body so that the food can be cooked quickly, thereby shortening the cooking time and saving energy. When the user presses the operating part to put the exhaust cover in the exhaust state, the inner cavity of the container body can be connected to the external environment through the exhaust channel of the exhaust cover, which is beneficial to reduce the risk of boiling and overflow of food during the cooking process. There is no need to remove the container lid for pressure relief during the exhaust process, which can improve the safety of the user during the cooking process and reduce the possibility of being scalded by steam.

[0062] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0063] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0065] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0066] The embodiment of the present application provides a container cover for covering a container body, such as Figure 1-Figure 3 As shown, the container cover includes an exhaust cover head 1 and a cover body 2, the exhaust cover head includes a main body 11 and an operating member 12, the main body 11 has an exhaust channel 111, the operating member 12 is rotatably connected to the main body 11 through a rotating shaft 13, wherein the operating member 12 includes a first blocking portion 121 and an operating portion 124, the rotating shaft 13 is located between the first blocking portion 121 and the operating portion 124, when the operating portion 124 is pressed, the operating member 12 can rotate relative to the main body 11, so that the first blocking portion 121 opens the exhaust channel 111.

[0067] In the embodiment of the present application, the first blocking portion 121 and the operating portion 124 are respectively arranged at the two ends of the operating member 12 along the second direction y. When the main body 11 and the operating member 12 are connected by the rotating shaft 13, the user can press the operating portion 124 to make the operating portion 124 move downward along the first direction x, and the operating member 12 rotates around the rotating shaft 13, thereby driving the first blocking portion 121 to move upward along the first direction x, thereby opening the exhaust channel 111. At this time, the exhaust cover 1 is in an exhaust state. When the user cancels the pressing of the operating portion 124, the operating portion 124 moves upward along the first direction x, and the operating member 12 rotates around the rotating shaft 13, thereby driving the first blocking portion 121 to move downward along the first direction x, thereby blocking the exhaust channel 111. At this time, the exhaust cover 1 is in a sealed state. Therefore, the exhaust cover 1 provided in the present application not only facilitates the user to take the container cover, but also has the functions of exhaust and sealing, so that the user can timely relieve the pressure in the container body during the cooking process to prevent the boiling food from overflowing, thereby improving the safety during cooking.

[0068] It should be noted that the first direction x mentioned in the embodiment of the present application may be the height direction of the exhaust cover head 1 , and the second direction y may be a direction perpendicular to the height direction of the exhaust cover head 1 , such as the width direction of the exhaust cover head 1 .

[0069] In a specific embodiment, Figure 1 As shown, the cover body 2 of the container cover is provided with a mounting hole (not shown in the figure), and the exhaust cover head 1 can be mounted on the cover body 2 through the mounting hole. Specifically, as shown in FIG. Figure 2 , Figure 3 and Figure 6As shown, the exhaust cover head 1 also includes a sealing ring 3, and the main body 11 also includes a step 115. The sealing ring 3 is sleeved on the step 115, so that after the exhaust cover head 1 and the cover body 2 are assembled, the exhaust cover head 1 can clamp the cover body 2 along the first direction x through the sealing ring 3 to prevent the steam in the container body from leaking from the mounting hole of the cover body 2 to the external environment, thereby helping to improve the sealing of the container cover.

[0070] When the container lid is closed on the container body, during the cooking process, the exhaust cover 1 in a sealed state will increase the pressure inside the container body so that the food can be cooked quickly, thereby shortening the cooking time and saving energy. When the user presses the operating part 124 to put the exhaust cover 1 in the exhaust state, the inner cavity of the container body can be connected to the external environment through the exhaust channel 111 of the exhaust cover 1, which is beneficial to reduce the risk of boiling and overflow of food during the cooking process. There is no need to remove the container lid for pressure relief during the exhaust process, which can improve the safety of users during the cooking process and reduce the possibility of being scalded by steam.

[0071] In a specific embodiment, Figure 2 and Figure 3 As shown, the exhaust cover head 1 further includes an elastic member 14, and two ends of the elastic member 14 are respectively connected to the operating portion 124 and the body 11.

[0072] In the embodiment of the present application, when the user presses the operating part 124, the operating part 124 can move downward along the first direction x, and in the process of downward movement, it applies pressure to the elastic member 14 together with the main body 11, so that the elastic member 14 is elastically deformed, and in the process of downward movement of the operating part 124, it drives the operating member 12 to rotate around the rotating shaft 13, and in the process of rotation, the operating member 12 drives the first blocking portion 121 to move upward along the first direction x, thereby opening the exhaust channel 111, at this time, the exhaust cover head 1 is in the exhaust state; when the user cancels the pressing force on the operating part 124, the elastic member 14 releases the rebound force, and under the action of the rebound force of the elastic member 14, the operating part 124 moves upward along the first direction x, so that the operating member 12 rotates around the rotating shaft 13, and in the process of rotation, the operating member 12 drives the first blocking portion 121 to move downward along the first direction x, thereby blocking the exhaust channel 111, at this time, the exhaust cover head 1 is in the sealing state.

[0073] Therefore, the elastic member 14 in the present embodiment will store rebound force when being squeezed. When the user no longer presses the operating part 124, the pressure on the elastic member 14 will disappear and the elastic member 14 will be able to recover its deformation, thereby driving the operating part 124 and the first blocking part 121 to automatically reset through the rebound force of the elastic member 14. There is no need to manually control the reset of the above-mentioned components, which simplifies the operating steps. At the same time, when the operating part 124 rotates downward along the first direction x, the elastic member 14 can prevent the operating part 124 from colliding violently with the main body 11, thereby protecting the internal structure of the exhaust cover 1, thereby increasing the service life of the exhaust cover 1.

[0074] In a specific embodiment, Figure 2 and Figure 3 As shown, the operating portion 124 has a mating surface 124a connected to the elastic member 14, the mating surface 124a is inclined downward along the height direction of the exhaust cover head 1, the main body 11 has a mounting groove 112, at least part of the elastic member 14 is located in the mounting groove 112, and when the first blocking portion 121 opens the exhaust channel 111, the mating surface 124a blocks the elastic member 14 in the mounting groove 112.

[0075] In the embodiment of the present application, the main body 11 is provided with an installation groove 112 for installing the elastic member 14, which is used to limit the movement of the elastic member 14 along the second direction y and the third direction z, so as to reduce the possibility of dislocation of the elastic member 14 when being squeezed, thereby improving the user's experience when pressing. When the elastic member 14 is installed in the mounting groove 112, at least a portion of the elastic member 14 can extend out of the mounting groove 112 along the first direction x and be connected to the mating surface 124a of the operating portion 124. When the user presses the operating portion 124 to put the exhaust cover 1 in the exhaust state, the operating portion 124 squeezes the elastic member 14 through the mating surface 124a and seals the elastic member 14 in the mounting groove 112. At this time, the steam in the container body flows out to the external environment through the exhaust channel 111. The mating surface 124a can prevent part of the steam from flowing into the mounting groove 112, thereby reducing the possibility of moisture corrosion of the elastic member 14, which is beneficial to increasing the service life of the elastic member 14. At the same time, the mating surface 124a is a plane inclined downward along the first direction x, so that it can fit with the surface of the mounting groove 112 when the exhaust cover 1 is exhausting, thereby improving the sealing effect, which is beneficial to further reduce the possibility of steam flowing into the mounting groove 112.

[0076] In a specific embodiment, Figure 2 , Figure 3 and Figure 6 As shown, the operating member 12 also includes a rotating portion 125 connected to the first blocking portion 121 and the operating portion 124. The rotating portion 125 is rotatably connected to the body 11 via the rotating shaft 13, and the rotating portion 125 has an arc surface. When the operating member 12 rotates relative to the body 11, the arc surface abuts against the body 11.

[0077] In the embodiment of the present application, after the operating member 12 is rotatably connected to the body 11 by the rotating shaft 13, the rotating portion 125 of the operating member 12 abuts against the body 11, and the surface where the rotating portion 125 of the operating member 12 abuts against the body 11 is an arc surface, which is beneficial to improving the smoothness of the user when driving the operating member 12 to rotate, and reducing the possibility of wear between the two during relative movement, thereby increasing the service life of the operating member 12 and the body 11. At the same time, the rotating portion 125 with the arc surface is convenient for the user to save effort and drive conveniently, so that the operating member 12 can be easily rotated around the rotating shaft 13 relative to the body 11, and then the exhaust cover head 1 can be freely switched between the sealing state and the exhaust state, thereby improving the user's experience. Specifically, Figure 5 and Figure 6 As shown, the rotating parts 125 are distributed at both ends of the operating member 12 along the third direction z, so that during the assembly of the exhaust cover head 1, the operating member 12 can clamp at least a portion of the main body 11 through the rotating parts 125 to improve the stability and reliability of the connection between the two. The operating member 12 is installed on the main body 11 through two rotating parts 125, which can improve the stability of the operating member 112 when rotating, thereby improving the working stability of the exhaust cover head 1.

[0078] In a possible embodiment, the main body 11 is provided with an arc-shaped groove matching with the rotating portion 125. During the assembly of the exhaust cover head 1, the rotating portion 125 of the operating member 12 can be inserted into the arc-shaped groove of the main body 11, so that when the operating member 12 rotates, the arc-shaped groove can provide a guiding effect, thereby further enhancing the smoothness of the rotation.

[0079] In a specific embodiment, Figure 2 , Figure 3 and Figure 6 As shown, the operating member 12 also includes a main body 126, and the first blocking portion 121, the rotating portion 125 and the operating portion 124 are all connected to the main body 126 to improve the overall structural stability of the operating member 12, so that the operating member 12 has good stability and reliability during operation.

[0080] In a possible implementation, the operating member 12 is an integrally formed structure, so that the operating member 12 has better structural stability and longer service life, thereby reducing the risk of other abnormal problems such as the first blocking portion 121 falling off during operation of the exhaust cover head 1.

[0081] Specifically, Figure 4As shown, the main body 11 has a accommodating cavity 113 and an opening 116 connected to the accommodating cavity 113. At least a portion of the operating member 12 is located in the accommodating cavity 113. When the first blocking portion 121 blocks the exhaust channel 111, the main body 126 of the operating member 12 blocks the opening 116. When the first blocking portion 121 fails, the main body 126 can seal the steam in the accommodating cavity 113 to reduce the possibility of steam leakage, thereby further enhancing the sealing performance of the exhaust cover 1, which is beneficial to improving the cooking efficiency of the user. At the same time, when the exhaust cover 1 is in a sealed state, the upper end surface of the main body 126 is flush with the upper end surface of the main body 11, which can facilitate the user to distinguish the working state of the exhaust cover 1, improve the identification effect, and avoid the user from touching the exhaust cover 1 when it is in the exhaust state, thereby reducing the risk of scalding the user and improving the user's experience.

[0082] In a possible implementation, the body 11 includes: Figure 4 The housing shown and Figure 6 The base shown in the figure has a housing cavity 113 and an opening 116. At the same time, the shell also has a through hole 117. The through hole 117 and the opening 116 are arranged opposite to each other along the first direction x. The operating member 12 is installed in the housing cavity 113 of the shell through the opening 116. The base is installed in the housing cavity 113 of the shell through the through hole 117. At least the parts of the operating member 12 and the base located in the housing cavity 113 are connected to the shell through the rotating shaft 13, so that the operating member 12 can rotate relative to the shell and the base, thereby realizing the free conversion of the exhaust cover head 1 between the sealing state and the exhaust state.

[0083] In a specific embodiment, Figure 2 and Figure 3 As shown, the first blocking portion 121 is located in the accommodating cavity 113, and the exhaust cover head 1 also includes an isolating portion 15 connected to the main body 11 and the operating member 12, and the isolating portion 15 divides the accommodating cavity 113 into a first cavity 113a and a second cavity 113b, at least part of the structure of the first blocking portion 121 is located in the first cavity 113a, and at least part of the structure of the operating portion 124 is located in the second cavity 113b.

[0084] In the embodiment of the present application, after the exhaust cover head 1 is assembled, the isolation portion 15 separates the accommodating chamber 113 into a first cavity 113a and a second cavity 113b. Specifically, the first blocking portion 121 and the exhaust channel 111 are located in the first cavity 113a, and the operating portion 124, the elastic member 14 and the mounting groove 112 are located in the second cavity 113b. The first cavity 113a and the second cavity 113b are not connected. When the exhaust cover head 1 is in the exhaust state, the first blocking portion 121 in the first cavity 113a opens the exhaust channel 111, and the container body The steam inside flows into the first cavity 113a through the exhaust channel 111. At this time, the isolation part 15 can block the steam in the first cavity 113a, reduce the possibility of steam flowing into the second cavity 113b, improve the protection effect of the elastic member 14, and reduce the risk of the elastic member 14 being corroded by moisture. At the same time, when the exhaust cover 1 is in a sealed state, the isolation part 15 and the operating part 12 can improve the sealing of the first cavity 113a to reduce the possibility of steam leaking from the first cavity 113a to the external environment, which is beneficial to improve cooking efficiency.

[0085] In a specific embodiment, Figure 2 , Figure 3 and Figure 4 As shown, the exhaust cover 1 also includes a second blocking portion 122 located in the second cavity 113b, and the side wall of the second cavity 113b is provided with a groove 114. The operating member 12 also includes a limiting portion 127 extending outward relative to the operating portion 124. When the first blocking portion 121 opens the exhaust channel 111, the second blocking portion 122 is fitted with the body 11 to separate the second cavity 113b from the external environment, and the limiting portion 127 abuts against the bottom wall of the groove 114.

[0086] In the embodiment of the present application, the second blocking portion 122 extends downward along the first direction x relative to the operating portion 124, and the limiting portion 127 extends along the second direction y relative to the operating portion 124 in a direction away from the first blocking portion 121. When the user presses the operating portion 124 to make it move downward along the first direction x, the matching surface 124a can squeeze the elastic member 14 and retract it into the installation groove 112. The second blocking portion 122 and the limiting portion 127 move downward along the first direction x synchronously with the operating portion 124. When the matching surface 124a is in contact with the upper end surface of the installation groove 112, the second blocking portion 122 and the limiting portion 127 are in contact with the upper end surface of the installation groove 112. The portion 122 abuts against the body 11 to seal the second cavity 113b, reducing the possibility that the steam leaking into the second cavity 113b flows out to the external environment through the groove 114, thereby reducing the risk of scalding the user, and the limiting portion 127 abuts against the bottom wall of the groove 114 to further seal the second cavity 113b, thereby improving the sealing effect of the second cavity 113b and limiting the stroke of the operating portion 124 to ensure that after the user cancels the external force pressing the operating portion 124, the operating portion 124 can be reset under the action of the elastic member 14, thereby improving the user experience.

[0087] In a specific embodiment, Figure 6 As shown, the operating member 12 has a third blocking portion 123 . When the first blocking portion 121 blocks the exhaust passage 111 , the third blocking portion 123 blocks the first cavity 113 a .

[0088] In the embodiment of the present application, the third sealing portion 123 extends relative to the first sealing portion 121 along the second direction y in a direction away from the operating portion 124. When the exhaust cover 1 is in a sealed state, the first sealing portion 121 blocks the exhaust channel 111, and the third sealing portion 123 abuts against the inner wall of the first cavity 113a to seal the first cavity 113a, thereby improving the sealing of the first cavity 113a, thereby further reducing the possibility of air leakage in the exhaust cover 1 in a sealed state during the cooking process, so as to ensure that the food can be cooked under a high temperature and high pressure environment, which is beneficial to improving the cooking efficiency. At the same time, the third sealing portion 123 can also prevent external impurities from flowing into the first cavity 113, thereby reducing the possibility of external impurities flowing into the interior of the container through the exhaust channel 111 when the exhaust cover 1 is in the exhaust state, thereby reducing the risk of food contamination.

[0089] In a specific embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the first blocking portion 121 has a first inclined surface 121a, the body 11 has a second inclined surface 111a, the exhaust channel 111 extends from the second inclined surface 111a in a direction away from the operating member 12, and when the first inclined surface 121a is in contact with the second inclined surface 111a, the first blocking portion 121 blocks the exhaust channel 111.

[0090] In the embodiment of the present application, when the two surfaces that cooperate with the first sealing portion 121 and the main body 11 are both inclined surfaces, they have a good guiding effect, which facilitates the rotation of the operating part 12 and improves the tightness of the cooperation between the first sealing portion 121 and the main body 11. At the same time, when the first inclined surface 121a and the second inclined surface 111a cooperate with each other, the connection area between the first sealing portion 121 and the main body 11 is larger, which is beneficial to improve the stability and reliability of the connection between the two, thereby improving the sealing effect of the first sealing portion 121 on the exhaust channel 111, and further reducing the possibility of steam leakage.

[0091] In a possible implementation manner, the operating member 12 and the body 11 can be detachably connected via a rotating shaft 13 so as to clean the interior of the accommodating cavity and reduce the possibility of dirt and grime being trapped inside the exhaust cover head 1 .

[0092] The above describes in detail the structure, features and effects of the present application based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present application, but the present application does not limit the scope of implementation to what is shown in the drawings. Any changes made in accordance with the concept of the present application, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present application.
