Description

Technical Field

[0001] The present application relates to the technical field of pressure regulating valves for cookers, and in particular to a pressure regulating valve, a container cover and a cooking container. Background Art

[0002] The pressure cookers currently on the market generally control the pressure inside the cooker through a pressure regulating valve thereon to maintain a fixed pressure inside the cooker, thereby steaming and cooking the food inside the pressure cooker.

[0003] However, existing pressure regulating valves are mostly designed with two levels of high pressure and low pressure, which cannot meet the different food cooking requirements. Utility Model Content

[0004] The present application provides a pressure regulating valve, a container cover and a cooking container, which are intended to adjust the pressure of the pressure regulating valve according to the cooking requirements of the food.

[0005] The present application provides a pressure regulating valve in a first aspect for use in a cooking container, wherein the cooking container has a cooking cavity; the pressure regulating valve comprises:

[0006] A valve seat, wherein the valve seat is provided with an exhaust hole;

[0007] A valve body, wherein the valve body is connected to the valve seat to form a valve cavity, and the valve cavity is communicated with the exhaust hole;

[0008] A valve core assembly, the valve core assembly is disposed in the valve cavity and is rotatably connected to the valve body, and the valve core assembly can block the exhaust hole;

[0009] A pressure regulating member, which is sleeved on the valve body and can rotate relative to the valve body;

[0010] A connecting piece, wherein the connecting piece connects the pressure regulating piece and the valve core assembly, and the pressure regulating piece drives a part of the structure of the valve core assembly to rotate through the connecting piece, and at the same time drives a part of the structure of the valve core assembly to move up and down along the valve body to adjust the working state of the pressure regulating valve.

[0011] In the present application, the pressure regulating valve can be adjusted according to the cooking requirements of the food materials, so that the pressure regulating valve maintains different pressure states, thereby allowing the cooking cavity of the cooking container to maintain different pressure states.

[0012] When cooking hard-to-cook food in the cooking container, the pressure regulating member can be rotated clockwise, and the pressure regulating member drives part of the valve core assembly to rotate synchronously through the connecting member, and at the same time, part of the valve core assembly moves downward along the valve body toward the exhaust hole, increasing the sealing pressure of the valve core assembly on the exhaust hole. That is, the thrust that needs to be overcome when the gas in the cooking container is discharged outward along the exhaust hole is increased, so that the cooking container has a higher air pressure value, thereby speeding up the cooking time of hard-to-cook food.

[0013] When the gas pressure in the cooking container is increased to a level that can overcome the blocking pressure of the valve core assembly on the exhaust hole, the gas pressure can lift up part of the structure of the valve core assembly, so that part of the gas is discharged to the external environment through the exhaust hole, reducing the internal pressure of the cooking container, avoiding excessive pressure in the cooking container, and effectively preventing dangerous situations caused by excessive pressure in the cooking container. When the gas pressure in the cooking container is lower than the blocking pressure of the valve core assembly on the exhaust hole, the valve core assembly can block the exhaust hole again, so that the gas pressure in the cooking container is maintained within a certain range (such as high pressure).

[0014] When the cooking container is used to cook easy-to-cook food, the pressure regulating member can be rotated counterclockwise, and the pressure regulating member drives part of the valve core assembly to rotate synchronously through the connecting member, and at the same time, part of the valve core assembly moves upward along the valve body in a direction away from the exhaust hole (at this time, the valve core assembly still blocks the exhaust hole) to reduce the blocking pressure of the valve core assembly on the exhaust hole. That is, the thrust that the gas in the cooking container needs to overcome when it is discharged outward along the exhaust hole is reduced, so that the cooking container has a slightly higher air pressure value to prevent the food from being cooked too soft.

[0015] Afterwards, when the gas pressure in the cooking container is increased to a level that can overcome the blocking pressure of the valve core assembly on the exhaust hole, the gas pressure can lift up part of the valve core assembly, so that part of the gas is discharged to the external environment through the exhaust hole, reducing the internal pressure of the cooking container, avoiding excessive pressure in the cooking container, and effectively preventing dangerous situations caused by excessive pressure in the cooking container. When the gas pressure in the cooking container is lower than the blocking pressure of the valve core assembly on the exhaust hole, the valve core assembly can block the exhaust hole again, so that the gas pressure in the cooking container is maintained within a certain range (such as micro pressure).

[0016] In a possible design, the valve core assembly includes a first valve core, a second valve core and an elastic member;

[0017] The first valve core is connected to the pressure regulating member through the connecting member, one end of the elastic member is connected to the first valve core, and the other end is connected to the second valve core, and the second valve core blocks the exhaust hole;

[0018] When the first valve core is rotated, the first valve core can move relative to the second valve core, and the elastic member can be compressed or released to adjust the pressure applied to the second valve core.

[0019] In the present application, by rotating the pressure regulating member, the pressure regulating member drives the first valve core to rotate through the connecting member, and at the same time drives the first valve core to move up and down along the valve body to adjust the distance between the first valve core and the second valve core, thereby changing the compression ratio of the elastic member, and changing the pressure applied by the elastic member to the second valve core, so as to achieve the purpose of adjusting different pressures.

[0020] In a possible design, the first valve core is provided with a sleeved portion, and the second valve core is provided with a sleeved portion. The sleeved portion is sleeved on the outside of the sleeved portion, and the sleeved portion can move along the sleeved portion.

[0021] In the present application, the first valve core and the second valve core are matched by slidingly matching the sleeved portion of the first valve core and the sleeved portion of the second valve core. In addition, the travel of the second valve core can be limited by matching the sleeved portion and the sleeved portion, thereby reducing the risk of the second valve core tilting after being lifted by air pressure and being unable to block the exhaust hole again.

[0022] In a possible design, the first valve core is provided with a first limiting portion protruding along the sleeved portion, and the second valve core is provided with a second limiting portion protruding along the sleeved portion;

[0023] The elastic member is sleeved on the outer sides of the sleeved portion and the sleeved portion, one end of the elastic member abuts against the first limiting portion, and the other end abuts against the second limiting portion.

[0024] In the present application, by sleeved the elastic member on the outside of the sleeved part and the sleeved part, and pressing the elastic member between the first limiting part and the second limiting part, the first valve core is closer to or farther away from the second valve core, and the compression ratio of the elastic member is adjusted by compressing or releasing the elastic member. The structure is simple and maintenance is convenient.

[0025] In a possible design, the first valve core is further provided with a first connecting portion, and the second connecting portion is provided with an external thread;

[0026] The valve body is provided with a second connecting portion, and the second connecting portion is provided with an internal thread matching the external thread;

[0027] When the first valve core is rotated, the external thread can rotate along the internal thread to drive the first valve core to move relative to the second valve core.

[0028] In the present application, the first valve core and the valve body are screwed together to realize the spiral transmission of the two, which has a simple structure and stable transmission. That is, when the first valve core rotates, the external thread of the first valve core rotates along the internal thread of the valve body, generating a transmission effect, so that the first valve core moves along the valve body.

[0029] In addition, due to the pressure exerted by the elastic member on the first valve core, the external thread of the first valve core and the internal thread of the valve body are tightly matched, increasing the friction between the two when they rotate relative to each other, limiting the rotation of the first valve core relative to the valve body, so as to limit the movement of the first valve core along the valve body, thereby making the cooperation between the first valve core and the valve body self-locking, thereby ensuring the working stability of the pressure regulating valve.

[0030] In a possible design, the pressure regulating member is provided with a cavity, and the cavity is communicated with the valve cavity;

[0031] The first valve core is provided with a limiting portion, and at least a part of the limiting portion can extend into the cavity;

[0032] The limiting portion is provided with an avoidance hole, the pressure regulating member is provided with a connecting hole, the connecting holes are located on both sides of the avoidance hole, and the connecting member connects the connecting hole and the avoidance hole;

[0033] During the movement of the first valve core, the connecting member can move relative to the avoidance hole.

[0034] In the present application, the connecting member is sequentially inserted into the connecting hole on one side, the avoidance hole and the connecting hole on the other side to connect the first valve core and the pressure regulating member. The pressure regulating member is sleeved on the valve body, the valve core assembly is rotatably connected to the valve body, and the connecting member connects the pressure regulating member and the valve core assembly, that is, the relative position of the pressure regulating member and the valve body is fixed.

[0035] The avoidance hole is a long hole structure, and when the first valve core moves along the valve body, the connecting piece can move relative to the avoidance hole to avoid the movement of the first valve core.

[0036] In a possible design, the second valve core is provided with a sealing portion, the sealing portion is conical, and a partial structure of the sealing portion can extend into the exhaust hole.

[0037] In the present application, the sealing structure is set as a conical structure. When the exhaust hole is blocked and opened, part of the structure of the sealing part can be inside the exhaust hole to limit the movement of the second valve core.

[0038] In a possible design, the pressure regulating valve further includes a sealing member;

[0039] The valve seat is provided with a sealing groove, a part of the structure of the sealing member is arranged in the sealing groove, and the sealing member is used to seal the matching position of the valve seat and the cover body.

[0040] In the present application, when the valve seat and the cover body are matched, the sealing member can be compressed so that the sealing member seals the matching position of the valve seat and the cover body to reduce the risk of gas leakage along the matching position of the valve seat and the cover body.

[0041] A second aspect of the present application provides a container cover, the container cover comprising:

[0042] Cover body;

[0043] A pressure regulating valve is installed on the cover body, and the pressure regulating valve is the pressure regulating valve described above.

[0044] In the present application, since the pressure regulating valve has the above-mentioned technical effects, the container cover including the pressure regulating valve should also have the corresponding technical effects, which will not be described in detail here.

[0046] container body;

[0047] A container cover, which can be covered on the container body, and the container cover is the container cover described above.

[0048] In the present application, since the pressure regulating valve has the above-mentioned technical effects, the cooking container including the pressure regulating valve should also have the corresponding technical effects, which will not be described in detail here.

[0092] 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.

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.

[0095] 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.

[0096] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0097] This embodiment provides a cooking container, which may be a pressure cooker. The cooking container comprises a container body and a container cover, wherein the container cover can be covered on the container body, and the container cover and the container body form a closed cooking cavity.

[0098] The container cover includes a cover body and a pressure regulating valve 1, and the cover body is provided with a through hole, which is connected to the cooking cavity. The pressure regulating valve 1 is installed on the cover body, and the exhaust hole 111 of the pressure regulating valve 1 is connected to the through hole. That is, the exhaust hole 111 is connected to the cooking cavity through the through hole. When the cooking container is initially working, part of the structure of the pressure regulating valve 1 can block the exhaust hole 111, so that the air pressure in the cooking cavity is higher than the external atmospheric pressure, so as to speed up the cooking time. When the air pressure in the cooking cavity is higher than the pressure limit value of the pressure regulating valve 1, the air pressure can push open the structure of the pressure regulating valve 1 that blocks the exhaust hole 111, so that the gas in the cooking cavity is discharged to the external environment along the through hole and the exhaust hole 111, so that the air pressure in the cooking container is maintained within a certain range.

[0099] The pressure limit value of the pressure regulating valve 1 refers to the blocking pressure of the pressure regulating valve 1 on the exhaust hole 111, that is, the pressure value overcome by the gas in the cooking container when the gas pushes open part of the structure of the pressure regulating valve 1 to exhaust outward along the exhaust hole 111. The user can adjust the pressure limit value of the pressure regulating valve 1 according to the degree of cooking of the ingredients. The structure of the pressure regulating valve 1 will be described in detail below with reference to the accompanying drawings.

[0100] like Figure 1 The figure shows a cross-sectional schematic diagram of a pressure regulating valve 1, which includes a valve seat 11, a valve body 12, a valve core assembly 13, a pressure regulating member 14 and a connecting member 15. The valve body 12 is connected to the valve seat 11 to form a valve cavity 121. The valve seat 11 is provided with an exhaust hole 111, and the valve cavity 121 is connected to the exhaust hole 111. The valve core assembly 13 is arranged in the valve cavity 121 and is rotatably connected to the valve body 12. Part of the structure of the valve core assembly 13 can block the exhaust hole 111. The pressure regulating member 14 is sleeved on the valve body 12 and can rotate relative to the valve body 12. The connecting member 15 connects the pressure regulating member 14 and the valve core assembly 13. Among them, the pressure regulating member 14 is sleeved on the valve body 12, the valve core assembly 13 is rotatably connected to the valve body 12, and the connecting member 15 connects the pressure regulating member 14 and the valve core assembly 13, that is, the relative position of the pressure regulating member 14 and the valve body 12 is fixed.

[0101] When adjusting the pressure limit value of the pressure regulating valve 1, it is necessary to rotate the pressure regulating member 14. The pressure regulating member 14 drives part of the structure of the valve core assembly 13 to rotate through the connecting member 15, and at the same time drives part of the structure of the valve core assembly 13 to move up and down along the valve body 12 to adjust the pressure of the pressure regulating valve 1 and maintain the pressure regulating valve 1 in different working states.

[0102] Specifically, in this embodiment, the pressure regulating valve 1 can be adjusted according to the cooking requirements of the food, so that the pressure regulating valve 1 maintains different pressure states, thereby maintaining the cooking cavity of the cooking container at different pressure states.

[0103] For example, when the cooking container is used to cook hard-to-cook food, the pressure regulating member 14 can be rotated clockwise, and the pressure regulating member 14 drives part of the structure of the valve core assembly 13 to rotate synchronously through the connecting member 15, and at the same time, part of the structure of the valve core assembly 13 moves downward along the valve body 12 toward the exhaust hole 111, thereby increasing the blocking pressure of the valve core assembly 13 on the exhaust hole 111. That is, the thrust that needs to be overcome when the gas in the cooking container is discharged outward along the exhaust hole 111 is increased, so that the cooking container has a higher air pressure value, thereby speeding up the cooking time of hard-to-cook food.

[0104] Thereafter, when the gas pressure in the cooking container is increased to a level that can overcome the blocking pressure of the valve core assembly 13 on the exhaust hole 111, the gas pressure can lift up part of the structure of the valve core assembly 13, so that part of the gas is discharged to the external environment through the exhaust hole 111, reducing the internal pressure of the cooking container, avoiding excessive pressure in the cooking container, and effectively preventing dangerous situations caused by excessive pressure in the cooking container. When the gas pressure in the cooking container is lower than the blocking pressure of the valve core assembly 13 on the exhaust hole 111, the valve core assembly 13 can block the exhaust hole 111 again, so that the gas pressure in the cooking container is maintained within a certain range (such as high pressure).

[0105] When the cooking container is used to cook easy-to-cook food, the pressure regulating member 14 can be rotated counterclockwise, and the pressure regulating member 14 drives part of the structure of the valve core assembly 13 to rotate synchronously through the connecting member 15. At the same time, part of the structure of the valve core assembly 13 moves upward along the valve body 12 in a direction away from the exhaust hole 111 (at this time, the valve core assembly 13 still blocks the exhaust hole 111) to reduce the blocking pressure of the valve core assembly 13 on the exhaust hole 111. That is, the thrust that the gas in the cooking container needs to overcome when it is discharged outward along the exhaust hole 111 is reduced, so that the gas pressure in the cooking container is slightly higher, so as to prevent the food from being cooked too soft.

[0106] Thereafter, when the gas pressure in the cooking container is increased to a level that can overcome the blocking pressure of the valve core assembly 13 on the exhaust hole 111, the gas pressure can lift up part of the valve core assembly 13, so that part of the gas is discharged to the external environment through the exhaust hole 111, thereby reducing the internal pressure of the cooking container, avoiding excessive pressure in the cooking container, and effectively preventing dangerous situations caused by excessive pressure in the cooking container. When the gas pressure in the cooking container is lower than the blocking pressure of the valve core assembly 13 on the exhaust hole 111, the valve core assembly 13 can block the exhaust hole 111 again, so that the gas pressure in the cooking container is maintained within a certain range (such as micro pressure).

[0107] Furthermore, the side wall of the valve body 12 is provided with a vent hole 123 connecting the external environment and the valve cavity 121 . When the valve core assembly 13 opens the exhaust hole 111 , the gas can be discharged to the external environment along the exhaust hole 111 , the valve cavity 121 and the vent hole 123 .

[0108] It should be noted that the pressure regulating valve 1 can adjust the pressure limit value according to the cooking requirements of different ingredients. Specifically, corresponding marks can be set on the pressure regulating member 14 and the outer wall of the valve body 12, and the approximate cooking pressure corresponding to the ingredients can be given on each mark. The user can rotate the pressure regulating member 14 according to the ingredients to point to the corresponding mark on the outer wall of the valve body 12, so that the pressure regulating valve 1 forms a corresponding pressure limit value, thereby maintaining the corresponding air pressure range inside the cooking container.

[0109] It should also be noted that when adjusting the pressure regulating valve 1, the pressure regulating member 14 can be rotated counterclockwise to drive part of the valve core assembly 13 to move downward, and the pressure regulating member 14 can be rotated clockwise to drive part of the valve core assembly 13 to move upward. The specific setting can be based on actual conditions and is not limited in this embodiment.

[0110] Furthermore, if Figure 2 The figure shows a cross-sectional view of the valve core assembly 13. In order to adjust the pressure regulating valve 1 to achieve different pressures, the valve core assembly 13 includes a first valve core 131, a second valve core 132 and an elastic member 133. Figure 1 and Figure 2 The first valve core 131 is connected to the pressure regulating member 14 through the connecting member 15 , one end of the elastic member 133 is connected to the first valve core 131 , and the other end is connected to the second valve core 132 , and the second valve core 132 blocks the exhaust hole 111 .

[0111] Please continue to refer to Figure 1 and Figure 2 When the first valve core 131 is rotated, the first valve core 131 can move relative to the second valve core 132 , and the elastic member 133 can be compressed or released to adjust the pressure applied to the second valve core 132 .

[0112] That is, in this embodiment, the pressure regulating member 14 is rotated, and the pressure regulating member 14 drives the first valve core 131 to rotate through the connecting member 15, and at the same time drives the first valve core 131 to move up and down along the valve body 12 to adjust the distance between the first valve core 131 and the second valve core 132, thereby changing the compression ratio of the elastic member 133, and changing the pressure applied by the elastic member 133 to the second valve core 132, so as to achieve the purpose of adjusting different pressures.

[0113] For example, Figure 3 The figure shows a cross-sectional view of the pressure regulating valve 1 in the maximum pressure state. By rotating the pressure regulating member 14, the first valve core 131 is driven to move to the position where the distance between the first valve core 131 and the second valve core 132 is the smallest. At this time, the distance S1 between the first valve core 131 and the second valve core 132 is the smallest. The first valve core 131 and the second valve core 132 compress the elastic member 133, and the elastic member 133 is subjected to the maximum pressure in the compressed state. Therefore, at this time, the pressure applied by the elastic member 133 to the second valve core 132 is the largest, so that the blocking pressure applied by the second valve core 132 to the exhaust hole 111 is the largest.

[0114] At this time, when the gas in the cooking cavity is exhausted to the outside along the exhaust hole 111, the pressure applied by the elastic member 133 to the second valve core 132 and the gravity of the second valve core 132 need to be overcome to push the second valve core 132 to move away from the exhaust hole 111 to open the exhaust hole 111. At this time, the position of the first valve core 131 remains unchanged. Figure 4 It is a cross-sectional schematic diagram showing that the valve core assembly 13 is lifted up by air pressure when the pressure regulating valve 1 is in the maximum pressure state.

[0115] like Figure 5 The figure shows a cross-sectional view of the pressure regulating valve 1 in the minimum pressure state. By rotating the pressure regulating member 14, the first valve core 131 is driven to move to the position where the distance between the first valve core 131 and the second valve core 132 is the largest. At this time, the distance S2 between the first valve core 131 and the second valve core 132 is the largest. The first valve core 131 and the second valve core 132 compress the elastic member 133, and the elastic member 133 bears the smallest pressure in the compressed state. Therefore, at this time, the pressure applied by the elastic member 133 to the second valve core 132 is the smallest, so that the blocking pressure applied by the second valve core 132 to the exhaust hole 111 is the smallest.

[0116] At this time, when the gas in the cooking cavity is exhausted to the outside along the exhaust hole 111, the pressure applied by the elastic member 133 to the second valve core 132 and the gravity of the second valve core 132 need to be overcome to push the second valve core 132 to move away from the exhaust hole 111 to open the exhaust hole 111. At this time, the position of the first valve core 131 remains unchanged. Figure 6 It is a cross-sectional schematic diagram showing that the valve core assembly 13 is lifted up by air pressure when the pressure regulating valve 1 is in the minimum pressure state.

[0117] Of course, the first valve core 131 can also be driven to move to the position where the pressure regulating member 14 is rotated. Figure 3 and Figure 5 The position between the two first valve cores 131 shown can be adjusted according to actual conditions.

[0118] like Figure 7 The figure shows a cross-sectional schematic diagram of the first valve core 131, and the first valve core 131 is provided with a sleeved portion 131a, a first limiting portion 131b, a first connecting portion 131c and a limiting portion 131d, and the sleeved portion 131a, the first limiting portion 131b, the first connecting portion 131c and the limiting portion 131d are integrally formed.

[0119] like Figure 8 The figure is a cross-sectional schematic diagram of the second valve core 132. The second valve core 132 is provided with a sleeve portion 132a, a second limiting portion 132b and a sealing portion 132c. The sleeve portion 132a, the second limiting portion 132b and the sealing portion 132c are integrally formed.

[0120] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The sleeve portion is provided with a receiving groove 132a1, the sleeve portion 132a is sleeved on the outside of the sleeved portion 131a, and part of the sleeved portion 131a is located in the receiving groove 132a1. When the first valve core 131 moves along the valve body 12, the sleeved portion 131a can move along the sleeve portion 132a, so that the first valve core 131 moves relative to the second valve core 132.

[0121] In this embodiment, the sleeved portion 131a of the first valve core 131 and the sleeved portion 132a of the second valve core 132 are slidably matched to achieve the matching of the first valve core 131 and the second valve core 132. In addition, the matching of the sleeved portion 131a and the sleeved portion 132a can limit the stroke of the second valve core 132, thereby reducing the risk of the second valve core 132 tilting after being lifted by air pressure and failing to block the exhaust hole 111 again.

[0122] Please continue to refer to Figure 7 The first limiting portion 131b protrudes around the sleeved portion 131a, and the first limiting portion 131b is located on the side of the sleeved portion 131a away from the sleeved portion 132a. Please continue to refer to Figure 8 The second limiting portion 132b protrudes around the sleeve portion 132a, and the second limiting portion 132b is located on the side of the sleeve portion 132a away from the sleeved portion 131a. Figure 2 , Figure 7 and Figure 8 The elastic member 133 is sleeved on the outside of the sleeve portion 132a and the sleeved portion 131a, and one end of the elastic member 133 abuts against the first limiting portion 131b, and the other end abuts against the second limiting portion 132b, thereby realizing the connection between the elastic member 133 and the first valve core 131 and the second valve core 132.

[0123] In this embodiment, the elastic member 133 is sleeved on the outer sides of the sleeved portion 131a and the sleeved portion 132a, and the elastic member 133 is pressed between the first limiting portion 131b and the second limiting portion 132b. When the first valve core 131 approaches or moves away from the second valve core 132, the elastic member 133 is compressed or released to adjust the compression ratio of the elastic member 133. The structure is simple and maintenance is convenient.

[0124] Please continue to refer to Figure 7 The first connection portion 131c is located on a side of the first limiting portion 131b away from the sleeved portion 131a, and an outer wall of the first connection portion 131c is provided with an external thread 131c1. Fig. 9The figure shows a cross-sectional view of the valve body 12. The valve body 12 is provided with a second connecting portion 122. The second connecting portion 122 is provided with an internal thread 122a that matches the external thread 131c1. Figure 1 , 7 and Fig. 9 When the first valve core 131 is rotated, the external thread 131c1 can rotate along the internal thread 122a to drive the first valve core 131 to move along the valve body 12, thereby realizing the movement of the first valve core 131 relative to the second valve core 132.

[0125] In this embodiment, the first valve core 131 and the valve body 12 are screwed together to realize the spiral transmission of the two, which has a simple structure and stable transmission. That is, when the first valve core 131 rotates, the external thread 131c1 of the first valve core 131 rotates along the internal thread 122a of the valve body 12, generating a transmission effect, so that the first valve core 131 moves along the valve body 12.

[0126] In addition, due to the pressure exerted by the elastic member 133 on the first valve core 131, the external thread 131c1 of the first valve core 131 is tightly matched with the internal thread 122a of the valve body 12, thereby increasing the friction of the two rotating relative to each other and limiting the rotation of the first valve core 131 relative to the valve body 12, so as to limit the movement of the first valve core 131 along the valve body 12, thereby making the cooperation between the first valve core 131 and the valve body 12 self-locking, thereby ensuring the working stability of the pressure regulating valve 1.

[0127] like Fig.10 The figure shows a cross-sectional view of the pressure regulating member 14. The pressure regulating member 14 can be a screw cap structure. The pressure regulating member is provided with a cavity 141 and a connecting hole 142. Please continue to refer to Figure 7 The limiting portion 131d is provided with an avoidance hole 131d1, and the avoidance hole 131d1 is a long hole structure. Figure 1 , Figure 7 and Fig.10 The pressure regulating member 14 is sleeved on the valve body 12, and the cavity 141 is connected to the valve cavity 121. At least part of the structure of the limit portion 131d can extend into the cavity 141. The connecting hole 142 is located on both sides of the avoidance hole 131d1, and the connecting member 15 is inserted into the connecting hole 142 on one side, the avoidance hole 131d1 and the connecting hole 142 on the other side in sequence to connect the first valve core 131 and the pressure regulating member 14.

[0128] The avoidance hole 131d1 is designed as a long hole structure. When the first valve core 131 moves along the valve body 12 , the connecting member 15 can move relative to the avoidance hole 131d1 to avoid the movement of the first valve core 131 .

[0129] Please continue to refer to Figure 8The sealing portion 132c is located on the side of the second limiting portion 132b away from the sleeve portion 132a, and the sealing portion 132c is conical. Figure 3 , Figure 5 and Figure 8 When the second valve core 132 blocks the exhaust hole 111 , a portion of the sealing portion 132 c can extend into the exhaust hole 111 and seal with the exhaust hole 111 .

[0130] Please refer to Figure 4 , Figure 6 and Figure 8 When the air pressure pushes the second valve core 132 open, part of the structure of the sealing portion 132c is still located in the exhaust hole 111, that is, the sealing portion 132c with a conical structure can gradually open the exhaust hole 111, reducing the risk of accidentally injuring the user due to rapid discharge of a large amount of gas.

[0131] In addition, the sealing portion 132 c is configured as a conical structure, and when the exhaust hole 111 is blocked or opened, a portion of the sealing portion 132 c can be within the exhaust hole 111 to limit the movement of the second valve core 132 .

[0132] It should be noted that when the air pressure in the cooking container is too high, the air pressure may also completely push the sealing portion 132 c out of the exhaust hole 111 .

[0133] like Fig.11 The figure shows a cross-sectional schematic diagram of the valve seat 11 and the sealing member 16. The valve seat 11 is further provided with an extension portion 113, and the exhaust hole 111 is provided through the extension portion 113. Part of the structure of the extension portion 113 can pass through the through hole of the cover body, and the outer side of the extension portion 113 is provided with a thread, and the nut can be threadedly connected with the extension portion 113 passing through the cover body to fix the valve seat 11 on the cover body, thereby realizing the connection between the pressure regulating valve 1 and the cover body.

[0134] Please refer to Figure 1 and Fig.11 The valve seat 11 is provided with a sealing groove 112, and the pressure regulating valve 1 further comprises a sealing member 16, and a part of the structure of the sealing member 16 is provided in the sealing groove 112. When the valve seat 11 is matched with the cover body, the sealing member 16 can be compressed so that the sealing member 16 seals the matching position of the valve seat 11 and the cover body, so as to reduce the risk of gas leakage along the matching position of the valve seat 11 and the cover body.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
