Description

Technical Field

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

[0002] The pressure cooker's exhaust port is equipped with an exhaust valve. When the pressure inside the cooker reaches a threshold, the gas inside pushes against the seal inside the exhaust valve, causing the valve to open and allow steam inside to escape through the valve, thereby reducing the pressure inside the cooker. In the prior art, the seal inside the exhaust valve is compressed by a spring. As the pressure inside the cooker rises, the spring deforms more, causing the seal to move upward, resulting in gas leakage when the pressure inside the cooker has not reached the threshold. Utility Model Content

[0003] The present application provides a container cover and a cooking container, which are used to solve the problem of gas leakage when the pressure does not reach a threshold.

[0004] An embodiment of the present application provides a container cover, comprising:

[0005] a cover body, the cover body including an exhaust hole;

[0006] an exhaust valve mounted on the lid, comprising a sealing member having a sealing protrusion on a side of the sealing member facing the lid, wherein the exhaust hole is located within the projection of the sealing protrusion when projected along the height direction of the container lid;

[0007] When the pressure on the side of the cover body away from the sealing member is less than a preset pressure, the sealing protrusion is compressed and abuts against the cover body; when the pressure on the side of the cover body away from the exhaust valve is greater than or equal to the preset pressure, the sealing protrusion returns to its initial state and separates from the cover body.

[0008] The side of the seal facing the cover body is used to block the exhaust hole. When the pressure on the side of the cover body away from the exhaust valve is higher, the gas on the side of the cover body away from the seal pushes the seal away from the cover body to release the blockage of the exhaust hole, allowing the gas to be discharged from the exhaust hole, thereby reducing the pressure on the side of the cover body away from the seal. When the pressure on the side of the cover body away from the exhaust valve reaches a preset pressure value, the gas on the side of the cover body away from the seal will push the seal away from the cover body until the sealing protrusion returns to its original shape and a gap is formed between the cover body and the seal, allowing the gas on the side of the cover body away from the seal to be discharged from the exhaust hole. The sealing protrusion provided on the side of the seal facing the cover body can form a pressure storage space, improve the stability of the exhaust valve's starting value, and reduce the influence of the power of the heating source on the side of the cover body away from the exhaust valve on the exhaust stability of the exhaust valve.

[0009] In a possible embodiment, the sealing protrusion includes a first main body portion and a second main body portion, and the second main body portion is located on a side of the first main body portion away from the sealing member; the width of the first main body portion is greater than the width of the second main body portion, and the width of the first main body portion gradually decreases along the direction approaching the second main body portion.

[0010] When the pressure on the side of the cover body away from the exhaust valve is less than the preset pressure, the sealing protrusion located between the cover body and the sealing member will be compressed. The second main body is located on the side of the first main body close to the cover body. The width of the second main body is smaller. As it approaches the second main body, the width of the first main body gradually decreases, making the sealing protrusion easy to deform and easy to be compressed.

[0011] In a possible embodiment, the relationship between the width d1 of the first main body portion and the width d2 of the second main body portion is: d1 ≥ d2.

[0012] When the seal moves toward the side away from the cover body, a pressure storage space is formed between the seal, the cover body and the sealing protrusion. The width of the first main body is greater than or equal to twice the width of the second main body, which can improve the pressure-bearing capacity of the pressure storage space and reduce the possibility of gas on the side of the cover body away from the seal leaking out of the pressure storage space.

[0013] In a possible embodiment, the sealing member and the sealing protrusion are made of silicone.

[0014] Silicone has good high-temperature resistance, allowing the seal and sealing protrusion to maintain their working performance in high-temperature environments. Silicone is also highly elastic and easily deformed. When the pressure on the side of the lid away from the exhaust valve is less than the preset pressure, the silicone sealing protrusion fits more tightly with the lid, reducing the possibility of air leakage. At the same time, silicone has a longer service life, which can also increase the service life of the container lid.

[0015] In a possible embodiment, the exhaust valve includes a mounting portion, a push rod and an elastic member, the sealing member is located between the mounting portion and the cover body, the push rod is connected to a side of the sealing member away from the cover body; one end of the elastic member is connected to a side of the push rod close to the sealing member, and the other end is connected to the mounting portion.

[0016] The push rod is connected to the sealing member. When the pressure on the side of the cover body away from the exhaust valve is less than a preset pressure, the elastic force of the elastic member is transmitted to the sealing member through the push rod, causing the sealing member to abut against the cover body, thereby blocking the exhaust hole. When the pressure on the side of the cover body away from the exhaust valve increases, the pressure on the side of the cover body away from the exhaust valve is transmitted to the elastic member through the sealing member and the push rod, compressing the elastic member. This in turn causes the push rod and the sealing member to move toward the side away from the cover body, thereby releasing the blockage of the exhaust hole and allowing the high-pressure gas on the side of the cover body away from the exhaust valve to be discharged.

[0017] In a possible embodiment, the sealing member includes a mounting groove, a clamping portion is provided in the mounting groove, and one end of the push rod is located in the mounting groove and is clamped with the clamping portion.

[0018] The clamping portion protrudes from the inner wall of the mounting groove, and the end of the push rod is located between the clamping portion and the bottom wall of the mounting groove, and is clamped with the clamping portion, limiting the relative position of the push rod and the seal along the height direction of the container cover. When the push rod drives the seal to move, the possibility of the push rod detaching from the mounting groove can be reduced.

[0019] In a possible embodiment, the sealing member includes a sealing portion, the sealing portion is connected to the mounting portion, and the push rod is located in the sealing portion.

[0020] The sealing portion is connected to the mounting portion, so that the sealing portion and the mounting groove form a closed space, thereby reducing the possibility of high-pressure gas discharged from the gap between the sealing member and the cover body entering the mounting groove.

[0021] In a possible embodiment, the sealing portion includes a bent section, and when the sealing member moves in a direction away from the cover body, the bent section is compressed.

[0022] By compressing or stretching the bent section, the installation groove can always be in a sealed state during the movement of the sealing member along the height direction of the container cover.

[0023] In a possible embodiment, a protrusion is further provided on a side of the sealing member facing the cover body, the protrusion passes through the exhaust hole, and a cross-sectional area of ​​the protrusion is smaller than or equal to a cross-sectional area of ​​the exhaust hole.

[0024] The raised portion is arranged on the sealing member and passes through the exhaust hole. When the raised portion moves with the sealing member, it can move relative to the exhaust hole, thereby reducing the possibility of the exhaust hole being blocked.

[0025] An embodiment of the present application further provides a cooking container, comprising a container body and a container cover, wherein the container cover is buckled onto the container body and is any one of the container covers described above.

[0026] The container lid is buckled onto the container body, so that the preset pressure can be maintained in the container body, which can speed up the cooking efficiency of the food in the container body. When the pressure in the container body is higher than the preset pressure, the high-pressure gas can be discharged through the exhaust valve to improve the safety of the cooking container.

[0027] The present application relates to a container lid and a cooking container. The container lid includes a lid body and an exhaust valve mounted on the lid body. The lid body includes an exhaust hole. A sealing protrusion is provided on the side of a sealing member in the exhaust valve that faces the lid body. When projected along the height direction of the container lid, the exhaust hole is within the projection of the sealing protrusion. When the pressure on the side of the lid body away from the exhaust valve is less than a preset pressure, the sealing protrusion is compressed and abuts against the lid body, allowing the exhaust valve to block the exhaust hole and reduce the possibility of high-pressure gas leakage. When the pressure on the side of the lid body away from the exhaust valve is greater than or equal to the preset pressure, the sealing protrusion returns to its initial state and separates from the lid body, allowing high-pressure gas to be discharged through the gap between the sealing protrusion and the lid body. When the sealing protrusion is not separated from the lid body, a pressure storage space is formed on the lid body, which improves the stability of the exhaust valve's discharge value and reduces the influence of the power of the heating source on the side of the lid body away from the exhaust valve on the exhaust valve's exhaust stability.

[0061] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cooking container, comprising a container body 3 and a container cover snapped onto the container body 3 .

[0062] The side of the container lid where the exhaust valve 2 is not provided is snapped onto the container body 3, so that the preset pressure can be maintained in the container body 3, which can speed up the cooking efficiency of the food in the container body 3. When the pressure in the container body 3 is greater than the preset pressure, the high-pressure gas can be discharged from the exhaust valve 2 to improve the safety of the cooking container.

[0063] like Figures 3 to 6As shown, an embodiment of the present application further provides a container lid, which includes a lid body 1 and an exhaust valve 2. The lid body 1 includes an exhaust hole 11, and the exhaust valve 2 is installed on the container lid to control the opening and closing of the exhaust hole 11. The exhaust valve 2 includes a sealing member 21. A sealing protrusion 22 is provided on the side of the sealing member 21 facing the lid body 1. When projected along the height direction of the container lid, the exhaust hole 11 is located within the projection range of the sealing protrusion 22, so that the sealing member 21 can block the exhaust hole 11. When the pressure on the side of the cover body 1 away from the exhaust valve 2 is less than the preset pressure, the sealing protrusion 22 is compressed and abuts against the cover body 1, reducing the possibility of gas leakage from the side of the cover body 1 away from the exhaust valve 2; as the pressure on the side of the cover body 1 away from the exhaust valve 2 increases, the sealing member 21 moves in the direction away from the cover body 1, and the sealing protrusion 22 gradually returns to its initial state; when the pressure on the side of the cover body 1 away from the exhaust valve 2 is greater than or equal to the preset pressure, the sealing protrusion 22 returns to its initial state and separates from the cover body 1, so that the gas on the side of the cover body 1 away from the exhaust valve 2 can be discharged from the gap between the sealing protrusion 22 and the cover body 1.

[0064] The side of the seal 21 facing the cover 1 is used to block the exhaust hole 11. When the pressure on the side of the cover 1 away from the exhaust valve 2 is high, the gas on the side of the cover 1 away from the seal 21 pushes the seal 21 away from the cover 1, thereby releasing the blockage of the exhaust hole 11 and allowing the gas to be discharged from the exhaust hole 11, thereby reducing the pressure on the side of the cover 1 away from the seal 21. When there is a certain pressure on the side of the cover 1 away from the exhaust valve 2 but the pressure value does not reach the preset pressure, the gas on the side of the cover 1 away from the seal 21 will also push the seal 21 away from the cover 1. The compressed sealing protrusion 22 will gradually return to its original shape as the seal 21 moves, forming a pressure storage space 4 between the cover 1 and the seal 21, reducing the possibility of gas leakage from the side of the cover 1 away from the exhaust valve 2 at this time. When the pressure on the side of the cover 1 away from the exhaust valve 2 reaches a preset pressure value, the gas on the side of the cover 1 away from the seal 21 will push the seal 21 away from the cover 1 until the sealing protrusion 22 returns to its original shape and a gap is formed between the cover 1, allowing the gas on the side of the cover 1 away from the seal 21 to be discharged through the exhaust hole 11. The sealing protrusion 22 provided on the side of the seal 21 facing the cover 1 can form a pressure storage space 4, thereby improving the stability of the exhaust value of the exhaust valve 2 and reducing the influence of the power of the heating source on the side of the cover 1 away from the exhaust valve 2 on the exhaust stability of the exhaust valve 2.

[0065] like Figures 3 to 6As shown, in one possible embodiment, the sealing protrusion 22 includes a first main portion 221 and a second main portion 222. The second main portion 222 is located on the side of the first main portion 221 away from the sealing member 21. When the pressure on the side of the cover body 1 away from the exhaust valve 2 is less than a preset pressure, both the first main portion 221 and the second main portion 222 are compressed. The width d1 of the first main portion 221 is greater than the width d2 of the second main portion 222, and the width of the first main portion 221 gradually decreases as it approaches the second main portion 222.

[0066] When the pressure on the side of the cover body 1 away from the exhaust valve 2 is less than the preset pressure, the sealing protrusion 22 located between the cover body 1 and the sealing member 21 will be compressed. The second main body portion 222 is located on the side of the first main body portion 221 close to the cover body 1. The width of the second main body portion 222 is smaller. Along the direction approaching the second main body portion 222, the width of the first main body portion 221 gradually decreases, making the sealing protrusion 22 easy to deform and easy to be compressed.

[0067] like Figure 3 As shown, in a possible embodiment, the width d1 of the first main body portion 221 is greater than the width d2 of the second main body portion 222 , and the relationship between d1 and 2d2 is: d1 ≥ 2d2.

[0068] When there is a certain pressure on the side of the cover body 1 away from the exhaust valve 2 but the pressure value does not reach the preset pressure, the seal 21 moves toward the side away from the cover body 1, so that a pressure storage space 4 is formed between the seal 21, the cover body 1 and the sealing protrusion 22. The width of the first main body 221 is greater than or equal to twice the width of the second main body 222, which can improve the ability of the pressure storage space 4 to withstand pressure and reduce the possibility of gas on the side of the cover body 1 away from the seal 21 leaking out of the pressure storage space 4.

[0069] The length, width, and other dimensions of the sealing protrusion 22 can be determined based on the preset pressure. For example, if the preset pressure is 35 kPa, the width d2 of the second main portion 222 can be 0.3 mm, and the height h of the second main portion 222 can be 0.3 mm to 0.8 mm. This ensures that the operating pressure on the side of the container lid away from the seal 21 is within a ±3 kPa tolerance of the preset pressure. When there is no pressure on the side of the lid body 1 away from the exhaust valve 2, the sealing protrusion 22 is compressed, and its deformation can be 0.5 mm. When pressure is applied to the side of the cover 1 away from the exhaust valve 2, but the pressure is less than 35 kPa, the seal 21 moves less than 0.5 mm away from the cover 1 as the pressure increases. The height of the second main portion 222 is 0.3 mm to 0.8 mm, ensuring that after the seal 21 moves, the second main portion 222 remains compressed and in contact with the cover 1, forming a pressure storage space 4 between the seal 21 and the cover 1. The width of the second main portion 222 is 0.3 mm, which improves the pressure storage capacity of the pressure storage space 4 and reduces the possibility of gas leakage from the pressure storage space 4. When the pressure on the side of the cover 1 away from the exhaust valve 2 is greater than 35 kPa, the seal 21 moves more than 0.5 mm away from the cover 1, causing the sealing protrusion 22 to return to its original shape and creating a gap between the seal 21 and the cover 1. This allows gas in the pressure storage space 4 to be discharged through the gap between the sealing protrusion 22 and the cover 1, thereby reducing the pressure on the side of the cover 1 away from the exhaust valve 2.

[0070] In a possible embodiment, the sealing member 21 and the sealing protrusion 22 are an integrally formed structure, and the sealing member 21 and the sealing protrusion 22 are both made of silicone.

[0071] Silicone has good high-temperature resistance, allowing the seal 21 and the sealing protrusion 22 to maintain their working performance in high-temperature environments. Silicone also has good elasticity and is easy to deform. When the pressure on the side of the cover 1 away from the exhaust valve 2 is less than the preset pressure, the silicone sealing protrusion 22 fits more tightly with the cover 1, reducing the possibility of gas leakage. At the same time, silicone has a long service life, which can increase the service life of the container cover. The seal 21 and the sealing protrusion 22 are an integrally formed structure, which can improve the pressure-bearing capacity of the pressure storage space 4 and reduce the possibility of gas in the pressure storage space 4 leaking out from the connection between the seal 21 and the sealing protrusion 22.

[0072] like Figure 3 and Figure 7 As shown, in a possible embodiment, a protrusion 26 is further provided on the side of the sealing member 21 facing the cover body 1, and the protrusion 26 is located inside the sealing protrusion 22. The protrusion 26 passes through the exhaust hole 11, and the cross-sectional area of ​​the protrusion 26 is less than or equal to the cross-sectional area of ​​the exhaust hole 11.

[0073] The protrusion 26 is provided on the sealing member 21 and passes through the exhaust hole 11. When the protrusion 26 moves with the sealing member 21, it can move relative to the exhaust hole 11, thereby reducing the possibility of the vent hole being blocked.

[0074] like Figure 3 As shown, in a possible embodiment, the exhaust valve 2 further includes a mounting portion 23, a push rod 24, and an elastic member 25. The sealing member 21 and the push rod 24 are both located between the mounting portion 23 and the cover body 1, and the push rod 24 is located on the side of the sealing member 21 away from the cover body 1. The elastic member 25 is located between the push rod 24 and the mounting portion 23. One end of the elastic member 25 is connected to the push rod 24, and the other end is connected to the mounting portion 23.

[0075] The push rod 24 is connected to the sealing member 21. The elastic member 25 can be a spring and is sleeved on the push rod 24. When the pressure on the side of the cover body 1 away from the exhaust valve 2 is less than a preset pressure, the elastic force of the elastic member 25 is transmitted to the sealing member 21 through the push rod 24, causing the sealing member 21 to abut against the cover body 1 to block the exhaust hole 11. When the pressure on the side of the cover body 1 away from the exhaust valve 2 increases, the pressure on the side of the cover body 1 away from the exhaust valve 2 is transmitted to the elastic member 25 through the seal 21 and the push rod 24, causing the elastic member 25 to compress, thereby causing the push rod 24 and the seal 21 to move toward the side away from the cover body 1, thereby releasing the blockage of the exhaust hole 11 and allowing the high-pressure gas on the side of the cover body 1 away from the exhaust valve 2 to be discharged.

[0076] like Figure 3 As shown, in one possible embodiment, the sealing member 21 includes a mounting groove 211, which is located on a side of the sealing member 21 away from the cover body 1. One end of the push rod 24 extends into the mounting groove 211 and engages with a clamping portion 212 provided in the mounting groove 211 to limit the relative position of the push rod 24 and the sealing member 21.

[0077] The clamping portion 212 protrudes from the inner wall of the mounting groove 211, and the end of the push rod 24 is located between the clamping portion 212 and the bottom wall of the mounting groove 211, and is clamped with the clamping portion 212, limiting the relative position of the push rod 24 and the sealing member 21 along the height direction of the container cover. When the push rod 24 drives the sealing member 21 to move, the possibility of the push rod 24 being separated from the mounting groove 211 can be reduced.

[0078] like Figure 3 and Figure 7 As shown, in a possible embodiment, the seal 21 includes a sealing portion 213, which is located on a side of the mounting groove 211 close to the mounting portion 23 and connected to the side wall of the mounting groove 211, and an end of the sealing portion 213 away from the mounting groove 211 is connected to the mounting portion 23, and the push rod 24 is located in the sealing portion 213.

[0079] The sealing portion 213 is connected to the mounting portion 23, forming a sealed space with the mounting groove 211. This reduces the possibility of high-pressure gas discharged from the gap between the sealing member 21 and the cover 1 entering the mounting groove 211. The exhaust valve 2 includes an exhaust passage 27, which is located outside the sealed space formed by the sealing portion 213 and the mounting groove 211. High-pressure gas discharged from the gap between the sealing member 21 and the cover 1 is discharged from the exhaust valve 2 through the exhaust passage 27.

[0080] like Figure 3 As shown, in a possible embodiment, the sealing portion 213 includes a bending section 213a, one end of the bending section 213a is connected to the mounting portion 23, and the other end is connected to the side wall of the mounting groove 211. When the sealing member 21 moves away from the cover body 1, the bending section 213a is compressed, and when the sealing member 21 abuts against the cover body 1, the bending section 213a is stretched.

[0081] By compressing or stretching the bent section 213 a , the mounting groove 211 can always be in a sealed state during the movement of the sealing member 21 along the height direction of the container cover.

[0082] The present application relates to a container lid and a cooking container. The container lid includes a lid body 1 and an exhaust valve 2 mounted on the lid body 1. The lid body 1 includes an exhaust hole 11. A sealing protrusion 22 is provided on the side of the sealing member 21 facing the lid body 1. When projected along the height direction of the container lid, the exhaust hole 11 is within the projection of the sealing protrusion 22. When the pressure on the side of the lid body 1 away from the exhaust valve 2 is less than a preset pressure, the sealing protrusion 22 is compressed and abuts against the lid body 1, allowing the exhaust valve 2 to block the exhaust hole 11 and reduce the possibility of high-pressure gas leakage. When the pressure on the side of the lid body 1 away from the exhaust valve 2 is greater than or equal to the preset pressure, the sealing protrusion 22 returns to its initial state and separates from the lid body 1, allowing the high-pressure gas to be discharged through the gap between the sealing protrusion 22 and the lid body 1. When the sealing protrusion 22 is not separated from the cover body 1, a pressure storage space 4 is formed on the cover body 1, which improves the stability of the exhaust value of the exhaust valve 2 and reduces the influence of the power of the heating source on the side of the cover body 1 away from the exhaust valve 2 on the exhaust stability of the exhaust valve 2.

[0083] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
