Description

Technical Field

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

[0002] Pressure cookers are commonly used cooking containers. The principle is to increase the pressure inside the pot, thereby increasing the boiling point of the water inside the pot, so that the water in the pot can be heated to a higher temperature, thereby speeding up the cooking speed. Pressure cookers are equipped with an air pressure valve to control the pressure inside the pot so that the cooking container can work safely. However, the current air pressure valve is easily blocked by food in the pot, resulting in the air pressure valve being unable to release pressure normally. The pressure inside the pot is too high, which is easy to cause safety accidents and has poor safety. Utility Model Content

[0003] In view of this, the present application provides a safety valve and a cooking container, so as to solve the problem of poor safety of the exhaust valve in the prior art.

[0004] The present application provides a safety valve, the safety valve comprising:

[0005] A valve body, the valve body comprising a main body, the main body having an installation cavity, a side wall of the installation cavity having an exhaust hole, a bottom wall of the installation cavity having a first vent hole and a second vent hole, the first vent hole and the second vent hole being in communication with the interior of the pot body;

[0006] A valve stem, the valve stem is installed in the installation cavity, and the valve stem includes a first sealing portion and a second sealing portion connected to each other;

[0007] The valve stem is capable of moving relative to the valve body. When the valve stem is located at a first position, the first sealing portion closes the first air vent, and the second sealing portion closes the second air vent. When the valve stem is in a second position, the first air vent and the second air vent are in an open state.

[0008] When the pressure inside the cooking container is high, the gas inside the pot body can push the first sealing part through the first air vent, and push the second sealing part through the second air vent, so that the valve stem moves relative to the valve body, and the valve body can move away from the pot body along the height direction of the safety valve. The valve stem is located at the second position, the first sealing part is separated from the first air vent, and the second sealing part is separated from the second air vent. The gas inside the pot body can enter the installation cavity from the first air vent and the second air vent, and is further discharged to the outside from the side wall of the installation cavity, thereby achieving a decompression effect inside the pot body.

[0009] When the safety valve is accidentally blocked, a safety accident occurs. For example, when the first vent is blocked, the gas inside the pot can push the second vent to drive the valve stem to move to achieve the ventilation function, timely reduce the pressure in the cooking container, and maintain a safe state. Therefore, the safety valve provided in the embodiment of the present application can reduce the possibility of being blocked and has good reliability and safety. The safety valve provided in the present application can be used in conjunction with a traditional pressure valve. The cooking container can be provided with the safety valve provided in the present application and the traditional pressure valve on the cover body at the same time. When the cooking container is working normally, the exhaust and pressure relief of the cooking container are completed by the traditional pressure valve. When the traditional pressure valve is blocked, the cooking container can no longer exhaust and reduce the pressure through the traditional pressure valve, and the pressure value inside the cooking container will continue to increase until the safety valve provided in the embodiment of the present application is triggered. The cooking container can exhaust and reduce the pressure in time through the safety valve provided in the embodiment of the present application to avoid the pressure value of the cooking container from further increasing and causing a safety accident.

[0010] In a possible implementation, the second sealing portion extends along the height direction of the safety valve, at least a portion of the second sealing portion can extend into the second air vent, the valve stem includes a second sealing member, the second sealing member is sleeved on the second sealing portion, and the second sealing member can abut against the inner wall of the second air vent.

[0011] In a possible implementation manner, the valve stem includes a plurality of the second sealing portions, the mounting cavity includes a plurality of the second ventilation holes, and the second sealing portions are arranged corresponding to the second ventilation holes.

[0012] In a possible embodiment, the safety valve includes a fixing member, the main body has a mounting portion, the mounting portion is located on the bottom wall of the mounting cavity and extends along the height direction of the safety valve, the first vent hole passes through the mounting portion, at least part of the mounting portion is located outside the mounting cavity, the fixing member is sleeved on the mounting portion, and the cover body can be installed between the fixing member and the valve body.

[0013] In a possible implementation, part of the mounting portion is located inside the mounting cavity, the first sealing portion abuts against the mounting portion, the first sealing portion has a protrusion, the protrusion protrudes toward the first ventilation hole, and the protrusion can extend into the first ventilation hole.

[0014] In a possible implementation manner, the valve body includes a valve bonnet, the valve bonnet is mounted on the main body, the valve bonnet has a guide hole, the valve stem has a guide portion, and at least a portion of the guide portion is located in the guide hole.

[0018] In a possible implementation manner, the cover body has an exhaust valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a safety valve, the safety valve comprises a valve body 1 and a valve stem 2, the valve body 1 comprises a main body 11, the main body 11 has an installation cavity 111, the side wall of the installation cavity 111 has an exhaust hole 112, and the installation cavity 111 can be provided with a plurality of exhaust holes 112 to improve exhaust efficiency. The bottom wall of the installation cavity 111 has a first vent hole 113 and a second vent hole 114. The safety valve is used to be installed in a cooking container such as a pressure cooker, and as a pressure control device, it can achieve a control effect on the pressure inside the cooking container. Specifically, the first vent hole 113 and the second vent hole 114 are connected to the inside of the pot body, and the first vent hole 113 and the second vent hole 114 are both connected to the exhaust hole 112. The valve stem 2 is installed in the installation cavity 111, and the valve stem 2 comprises a first sealing portion 21 and a second sealing portion 22 connected to each other. The valve stem 2 can abut against the inner wall of the installation cavity 111, and can move relative to the valve body 1 along the inner wall of the installation cavity 111. The valve stem 2 can control the opening and closing states of the first vent hole 113 and the second vent hole 114 by movement, thereby realizing the function of controlling the internal air pressure of the cooking container.

[0050] like Figure 3 As shown, when the gas pressure inside the cooking container is relatively low, the valve stem 2 is located at the first position, the first sealing portion 21 closes the first vent hole 113, and the second sealing portion 22 closes the second vent hole 114. The first sealing portion 21 can close the first vent hole 113 by abutting against the bottom wall of the installation cavity 111, or a portion of the first sealing portion 21 can extend into the first vent hole 113 to achieve a sealing effect, and the second sealing portion 22 also seals the second vent hole 114 by a principle similar to that of the first sealing portion 21. When the first vent hole 113 and the second vent hole 114 are closed, the gas inside the pot body cannot enter the installation cavity 111 from the first vent hole 113 and the second vent hole 114, nor can it be discharged to the outside from the exhaust hole 112, which is convenient for increasing the gas pressure inside the pot body.

[0051] like Figure 4 As shown, when the pressure inside the cooking container is relatively high, the gas inside the pot body can push the first sealing part 21 through the first air vent 113, and push the second sealing part 22 through the second air vent 114, so that the valve stem 2 moves relative to the valve body 1, and the valve stem 2 can move in the direction away from the pot body along the height direction of the safety valve. The valve stem 2 is located in the second position, the first sealing part 21 is separated from the first air vent 113, and the second sealing part 22 is separated from the second air vent 114. The gas inside the pot body can enter the installation cavity 111 from the first air vent 113 and the second air vent 114, and further be discharged to the outside from the exhaust hole 112 on the side wall of the installation cavity 111, thereby achieving a decompression effect inside the pot body.

[0052] The safety valve provided in the embodiment of the present application includes a first vent hole 113 and a second vent hole 114. When the safety valve is accidentally blocked by food in the pot, for example, when the first vent hole 113 is blocked, the gas inside the pot can push the second sealing portion 22 through the second vent hole 114, thereby driving the valve stem 2 to move to achieve the ventilation function, timely reduce the pressure in the cooking container, and maintain a safe state. Therefore, the safety valve provided in the embodiment of the present application can reduce the possibility of being completely blocked, and has good reliability and safety. The safety valve provided in the embodiment of the present application can be used in conjunction with a traditional pressure valve. The cooking container can be provided with the safety valve provided in the embodiment of the present application and the traditional pressure valve on the cover 5. When the cooking container is working normally, the exhaust and pressure relief of the cooking container are completed by the traditional pressure valve. When the traditional pressure valve is blocked, the cooking container can no longer exhaust and reduce the pressure through the traditional pressure valve, and the pressure value inside the cooking container will continue to increase until the safety valve provided in the embodiment of the present application is triggered. The cooking container can exhaust and reduce the pressure in time through the safety valve provided in the embodiment of the present application to avoid further increase in the pressure value of the cooking container and causing safety accidents.

[0053] The safety valve provided in the embodiment of the present application can adjust the pressure value required for exhaust by the mass of the valve stem 2. A pressure valve with appropriate weight can be selected according to actual needs, and its mass can be adjusted by changing the volume or material of the valve stem 2.

[0054] like Figure 3 As shown, in a possible implementation, part of the mounting portion 115 is located inside the mounting cavity 111, the first sealing portion 21 abuts against the mounting portion 115, the second sealing portion 22 extends along the height direction of the safety valve, and at least part of the second sealing portion 22 can extend into the second vent hole 114. The valve stem 2 includes a second sealing member 25, which is sleeved on the second sealing member 22 and can abut against the inner wall of the second vent hole 114.

[0055] The first sealing portion 21 extends in the radial direction of the safety valve, and the second sealing portion 22 extends in the axial direction of the safety valve. The mounting portion 115 extends in a direction close to the first sealing portion 21, and the first sealing portion 21 can abut against the mounting portion 115 to seal the first vent 113. The second sealing portion 22 extends in a direction close to the second vent 114, so that at least part of the second sealing portion 22 can extend into the second vent, so that the second sealing portion 22 can seal the second vent 114. Therefore, the solution provided in the embodiment of the present application can improve the air tightness of the safety valve.

[0056] The material of the second sealing member 25 can be a material with an elastic member, and the second sealing member 25 can improve the sealing performance of the second sealing portion 22. When the pressure in the pot body is relatively low, the gas inside the pot body will not enter the installation cavity 111 from the second vent hole 114 and then leak from the exhaust hole 112, which is convenient for increasing the pressure inside the pot body. When the cover body 5 of the cooking container is provided with the safety valve and the traditional exhaust valve provided in the embodiment of the present application, when the pressure inside the pot body is relatively high and needs to be relieved, and the traditional exhaust valve of the cooking container is blocked, or the first vent hole 113 of the safety valve is accidentally blocked, the gas inside the pot body can push the second sealing portion 22 to move to open the second vent hole 114 for exhaust.

[0057] When the valve stem 2 moves from the first position to the second position to release air and pressure, when the air pressure in the cooking container is low, the valve stem 2 can automatically fall back. Since the valve stem 2 is pushed by the gas and moves and falls back under the action of gravity, a certain deviation will occur. Therefore, the fallen valve stem 2 can no longer automatically close the first vent hole 113 and the second vent hole 114, and the cooking container can no longer be pressurized normally. After the traditional pressure valve is blocked, because the safety valve provided in the embodiment of the present application can realize the pressure relief function, the cooking container can continue to complete cooking normally, but the operator may not know that the traditional pressure valve is blocked. When the gas pressure in the cooking container is relatively low, the valve stem 2 can automatically fall back. Since the valve stem 2 is pushed by the gas to move and falls back under the action of gravity, a certain deviation will occur, and because the second sealing member 25 is provided, the fallen valve stem 2 can no longer automatically close the first air hole 113 and the second air hole 114 again, and the valve stem 2 can only be manually installed to the first position. During the subsequent use of the cooking container by the operator, since the valve stem 2 of the safety valve provided in the embodiment of the present application is in the second position, the first air hole 113 and the second air hole 114 cannot be closed, and the cooking container cannot be pressurized normally, thereby reminding the operator to repair the cooking container in time.

[0058] like Figure 3 As shown, in a possible implementation, the valve stem 2 includes a plurality of second sealing portions 22 , the mounting cavity 111 includes a plurality of second vent holes 114 , and the second sealing portions 22 are arranged correspondingly to the second vent holes 114 .

[0059] The provision of multiple second vent holes 114 can improve the reliability of the safety valve. When the first vent hole 113 or the second vent hole 114 is blocked, the other second vent holes 114 can still achieve the exhaust function. Multiple second sealing portions 22 can be arranged at intervals along the circumference of the first sealing portion 21. For example, the valve stem 2 can be provided with four second sealing portions 22, and the valve body 1 can be provided with four second vent holes 114 accordingly. The diameter of the second vent hole 114 can be smaller than the diameter of the first vent hole 113, so as to reduce the possibility of foreign matter entering the second vent hole 114.

[0060] like Figure 3 and Figure 4 As shown, in a possible embodiment, the safety valve includes a fixing member 4, the main body 11 has a mounting portion 115, the mounting portion 115 is located on the bottom wall of the mounting cavity 111 and extends along the height direction of the safety valve, the first vent hole 113 passes through the mounting portion 115, at least part of the mounting portion 115 is located outside the mounting cavity 111, the fixing member 4 is sleeved on the mounting portion 115, and the cover body 5 can be installed between the fixing member 4 and the valve body 1.

[0061] The mounting portion 115 is used to connect with the cover 5 of the cooking container. Specifically, the cover 5 has a through hole, and at least part of the mounting portion 115 extends into the interior of the pot body through the through hole, and the first vent hole 113 passes through the mounting portion 115, so that the interior of the pot body can be connected with the safety valve through the mounting portion 115. The fixing member 4 is installed at one end of the mounting portion 115 close to the interior of the pot body. The fixing member 4 can be connected to the mounting portion 115 by a thread. The pot body is located between the fixing member 4 and the main body 11 and is clamped and limited, so the safety valve is installed on the pot body.

[0062] In a possible embodiment, part of the mounting portion 115 is located inside the mounting cavity 111 , the first sealing portion 21 abuts against the mounting portion 115 , and the first sealing portion 21 has a protrusion 211 , which protrudes toward the direction close to the first ventilation hole 113 , and the protrusion 211 can extend into the first ventilation hole 113 .

[0063] At least part of the protrusion 211 can extend into the first vent hole 113, and the gas inside the pot body pushes the protrusion 211 to drive the valve stem 2 to move. In the direction close to the first vent hole 113, the cross-sectional area of ​​the protrusion 211 gradually decreases. For example, the protrusion 211 can be set to a cone, and the cross-sectional area of ​​the end close to the inside of the pot body is smaller, and the cross-sectional area of ​​the end connected to the first sealing part 21 is larger. The protrusion 211 can guide the movement of the valve stem 2, and the protrusion 211 can abut against the inner wall of the first vent hole 113, thereby improving the air tightness of the valve stem 2.

[0064] like Figure 2 and Figure 3 As shown, in a possible implementation, the valve body 1 includes a valve bonnet 12 , which is mounted on the main body 11 . The valve bonnet 12 has a guide hole 121 , and the valve stem 2 has a guide portion 23 , at least part of which is located in the guide hole 121 .

[0065] The installation cavity 111 may be provided with an opening to facilitate the installation of the valve stem 2 inside the installation cavity 111. The valve cap 12 may be installed on the top of the main body 11 in a sleeve-type manner to achieve a certain sealing function for the installation cavity 111 and protect the valve stem 2 and other structures inside the sealing cavity. The valve cap 12 has a guide hole 121 that passes through the valve cap 12 along the height direction of the safety valve. The valve stem 2 has a guide portion 23 that extends along the height direction of the safety valve. The guide portion 23 passes through the guide hole 121. When the valve stem 2 moves, the guide hole 121 can limit and correct the movement of the guide rod, thereby achieving a guiding effect on the movement of the valve stem 2, so that the valve stem 2 can move stably.

[0066] like Figure 3 and Figure 4 As shown, in a possible implementation manner, the safety valve includes an elastic member 3 , and the elastic member 3 connects the valve stem 2 and the valve body 1 .

[0067] The elastic member 3 connects the valve stem 2 and the main body 11, or the elastic member 3 connects the valve stem 2 and the valve cap 12. The elastic member 3 is used to elastically connect the valve stem 2 and the valve body 1, and can play a buffering role when the valve stem 2 moves. When the gas in the pot body pushes the valve stem 2 to move, the elastic member 3 can be compressed and elastically deformed, so that the valve stem 2 moves smoothly. When the air pressure in the pot body decreases, the elastic member 3 restores the deformation and pushes the valve stem 2 to move in the direction close to the pot body. According to actual needs, setting the elastic member 3 of reasonable size and material can make the elastic member 3 have different elasticities, and then control the pressure inside the pot body required for the valve stem 2 to move to open the exhaust hole 112. The elastic member 3 can be a spring made of metal material, and the elastic member 3 can be sleeved on the guide portion 23, one end of the elastic member 3 abuts against the valve cap 12, and the other end abuts against the connecting portion.

[0068] like Figure 3 As shown, in a possible implementation, the first sealing portion 21 has a protrusion 211, the protrusion 211 protrudes toward the direction close to the first vent hole 113, and the cross-sectional area of ​​the protrusion 211 gradually decreases along the direction close to the second sealing portion 22. When installing the valve stem 2, the protrusion 211 can play a guiding role to facilitate installation, and the protrusion 211 can abut against the inner wall of the first vent hole 113 to improve the sealing effect.

[0069] like Figure 3 As shown, in a possible implementation manner, the valve stem 2 includes a first sealing member 24 , the first sealing member 24 is sleeved on the valve stem 2 , and the first sealing member 24 abuts against the inner wall of the installation cavity 111 .

[0070] The side wall of the first sealing part 21 may be provided with a mounting groove, and the first sealing member 24 may be made of an elastic material, such as rubber and silicone, etc. The first sealing member 24 is sleeved on the first sealing part 21 and installed in the mounting groove. The first sealing member 24 can fit tightly with the inner wall of the mounting cavity 111, so that the mounting cavity 111 can maintain good air tightness. The first sealing part 21 can divide the mounting cavity 111 into two parts, the top and the bottom. The exhaust hole 112 is located on the side wall at the bottom of the mounting cavity 111. The first sealing member 24 can reduce the possibility of water vapor in the pot body entering the top of the mounting cavity 111 through the airflow.

[0071] A card groove can be provided on one side of the main body 11 close to the pot body, and a third sealing member 26 is installed in the card groove. The third sealing member 26 is arranged around the second air vent 114 to improve the sealing between the main body 11 and the cover body 5. When the gas inside the pot body enters the installation cavity 111 from the second air vent 114, the possibility of air leakage between the cover body 5 and the main body 11 is reduced.

[0072] like Figure 3 and Figure 4 As shown, in a possible implementation manner, the pressure cooker includes a cooker body and a cover body 5, the cover body 5 has a safety valve, and the safety valve is the safety valve provided in any of the above embodiments.

[0073] The cover body 5 is provided with a safety valve for realizing the pressure limiting function. The safety valve has a first vent hole 113 and a second vent hole 114. Exhausting air through multiple channels can improve the safety of the pressure cooker.

[0074] In a possible embodiment, the cover body 5 has an exhaust valve.

[0075] The pressure cooker provided in the embodiment of the present application may include a safety valve and an exhaust valve arranged on the cover body 5, wherein the safety valve is the safety valve provided in any of the above embodiments, and the exhaust valve is a traditional exhaust device. When the exhaust valve is accidentally blocked, the excessive pressure in the pot body triggers the safety valve to exhaust, thereby improving the safety of the cooking container.

[0076] 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.
