Description

Technical Field

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

[0002] A cooking utensil generally includes a container cover and a container body, such as a pressure cooker. The container cover can be covered on the container body, and a sealing ring is provided on the container cover. When the pressure cooker is in a sealed state, the sealing ring can seal the gap between the container cover and the container, so that the gas in the cooking utensil cannot be discharged, thereby ensuring the sealing of the cooking utensil. When the pressure in the pressure cooker is high, the existing container cover cannot be in a pressure relief state, resulting in a continuous increase in the pressure in the pressure cooker, causing a safety hazard. Utility Model Content

[0003] In view of this, the present application provides a sealing ring of a cooking utensil, a container cover and a cooking utensil, so as to solve the problem in the prior art that the container cover cannot be in a pressure relief state, resulting in a continuous increase in the pressure in the cooking container, causing a safety hazard.

[0004] In a first aspect, an embodiment of the present application provides a sealing ring, comprising: a connecting portion; a sealing portion, the sealing portion having an inner end portion and an outer end portion which are arranged opposite to each other in a radial direction of the sealing ring, the inner end portion being connected to the connecting portion, and at least the sealing portion being elastically deformable; wherein a first groove is provided on an inner wall of the sealing portion, the first groove passing through the inner end portion and the outer end portion.

[0005] In this embodiment, the sealing ring has a connecting portion, which can facilitate the assembly of the sealing ring and improve the connection reliability of the sealing ring. The sealing ring also has a sealing portion, and at least the sealing portion can be elastically deformed, so that the sealing portion can switch its state in different use environments, thereby improving the applicability of the sealing ring. At the same time, a first groove running through the inner end and the outer end is provided on the inner wall of the sealing portion, and the first groove can be used for exhaust when the internal pressure of the cooking utensil is too high.

[0006] In a specific embodiment, the sealing portion includes a main body and a deformation section. Along the radial direction of the sealing ring, the deformation section is located between the main body and the connecting portion, and the deformation section connects the main body and the connecting portion. The thickness of the deformation section is less than the thickness of the main body.

[0007] In this embodiment, since the thickness of the deformation section of the sealing part is smaller than the thickness of the main body, the deformation section is easier to deform when the sealing part is subjected to external force. When the pressure in the cooking utensil is relatively large, the deformation section undergoes relatively large elastic deformation under the action of the pressure, that is, the deformation section deforms radially outward along the container cover under the action of the pressure, so that the main body of the sealing part is located between the first contact part and the third contact part, so that at least part of the structure of the sealing part is squeezed out, and then the first groove provided on the sealing part is connected to the outside, so that the gas in the cooking utensil can be discharged through the first groove on the sealing part. In this embodiment, by providing a deformation section with a smaller thickness, at least part of the structure of the sealing part is easier to be squeezed out under the action of pressure, thereby further realizing the rapid exhaust of the cooking utensil.

[0008] In a specific embodiment, along the thickness direction of the main body, the main body is provided with a second groove on a side away from the first groove.

[0009] In this embodiment, when the cooking utensil is in the first state, the main body on the sealing part abuts against the second contact part along the height direction of the container cover, and the second groove is provided on the side of the main body away from the first groove, so that the contact position between the main body and the second contact part is arc-shaped, which can increase the contact area between the main body and the second contact part, thereby improving the sealing effect of the sealing ring. When the cooking utensil is in the second state, the main body is located between the first contact part and the third contact part, and the second groove is provided away from the first groove. When the pressure is high, the main body is deformed along the radial direction of the container cover toward the second groove, thereby increasing the flow cross-sectional area of ​​the first groove, increasing the exhaust volume of the first groove, and then improving the pressure relief rate.

[0010] In a specific embodiment, the sealing portion is provided with a plurality of first grooves spaced apart along the circumference of the sealing ring, and the plurality of first grooves are evenly distributed.

[0011] In this embodiment, when the cooking utensil is in the second state, part of the structure of the sealing ring will be elastically deformed under the action of pressure, so that at least part of the structure of the sealing ring is located between the first contact part and the third contact part, so that the gas in the accommodating cavity can be quickly discharged through the first groove. When a plurality of first grooves are arranged on the sealing part and are evenly distributed at intervals, when any position of the sealing ring is squeezed out to be located between the first contact part and the third contact part, the sealing part of the sealing ring of this part can communicate with the accommodating cavity and the outside through the first groove, so that the gas in the accommodating cavity can be quickly discharged, thereby ensuring the pressure relief rate of the cooking utensil.

[0012] In a specific embodiment, along the height direction of the sealing ring, both ends of the connecting portion are connected to the sealing portion; and the two sealing portions are symmetrical with respect to the connecting portion.

[0013] In this embodiment, by providing two sealing parts symmetrical to the connecting part, when the cooking utensil is in the first state, the two sealing parts are respectively in contact with the cover body and the container body, thereby preventing gas from leaking between the container cover and the sealing ring, and between the container body and the sealing ring, and can further improve the sealing effect of the sealing ring on the cooking utensil. At the same time, the sealing ring in this embodiment is a symmetrical structure, and when the sealing ring is installed on the cover body, the installation direction of the sealing ring is not limited, thereby reducing the difficulty of assembly, and there is no need to additionally provide an error-proofing device for the sealing ring during the assembly process, which can simplify the assembly steps and reduce costs.

[0014] In a specific embodiment, the outer end portion protrudes relative to the sealing portion along a height direction of the sealing ring.

[0015] In this embodiment, when the cooking utensil is in the second state, at least part of the structure of the sealing portion is located between the first contact portion and the third contact portion. At this time, when the outer end portion of the sealing portion protrudes along the height direction of the container cover, the outer end portion can abut against the third contact portion of the container body, thereby supporting the sealing ring, improving the reliability of the container cover fitting to the container body, and preventing the bottom wall of the first groove from abutting against the third contact portion to cause the first groove to be blocked, so that the cooking utensil can exhaust air through the first groove.

[0016] In a specific embodiment, the distance between adjacent first grooves is 2.5 mm-3.5 mm, and / or the width of the first groove is 1.8 mm-2.2 mm.

[0017] In this embodiment, the distance between adjacent first grooves should not be too large or too small. When it is too large, the sealing ring between the third contact part and the first contact part in the second state will not be provided with a first groove or the number of first grooves will be too small, affecting the pressure relief efficiency of the cooking utensil. When it is too small, the overall strength and rigidity of the sealing ring will decrease, affecting the sealing reliability of the cooking utensil in the first state. In this embodiment, when the distance between adjacent first grooves is 2.5mm-3.5mm, the sealing reliability of the cooking utensil in the first state is high, and the pressure can be quickly relieved in the second state.

[0018] The width of the first groove should not be too large or too small. When it is too large, the overall strength and rigidity of the sealing ring will decrease, affecting the sealing reliability of the cooking appliance in the first state. When it is too small, the flow cross-sectional area of ​​the first groove will be too small, making the exhaust volume of the first groove too small, affecting the pressure relief rate of the cooking appliance. In this embodiment, when the width of the first groove is 1.8mm-2.2mm, the sealing reliability of the cooking appliance in the first state is high, and the pressure relief can be quickly released in the second state.

[0019] In a second aspect, the present application provides a container cover, comprising: a cover body and a sealing ring, wherein the cover body has a mounting groove, wherein the connecting portion is mounted in the mounting groove.

[0020] In this embodiment, when the sealing ring is installed on the cover body, the cover body is provided with an installation groove, so that the connecting portion of the sealing ring can be installed in the installation groove, thereby improving the connection reliability between the sealing ring and the cover body, avoiding the phenomenon of the sealing ring falling off during the transportation or use of the container cover, and improving the safety of the container cover. At the same time, the sealing portion of the sealing ring can be elastically deformed, so that the container cover has at least a first state and a second state, the first state is a sealing state, and the second state is a pressure relief state, that is, the sealing ring enables the container cover to have at least a sealing state and a pressure relief state to meet the user's use requirements. The first groove of the sealing ring runs through the inner end and the outer end of the sealing ring. When the sealing ring is in the second state, the first groove connects the interior of the container cover with the outside, thereby ensuring that the container cover can be exhausted through the first groove in the second state.

[0021] In a specific embodiment, the connecting portion is interference fit or snap-fitted with the mounting groove.

[0022] In this embodiment, the connecting part and the mounting groove can be interference fit or snap-fit, making the connection between the connecting part and the mounting groove more reliable, avoiding the sealing ring from falling off during use or transportation, and reducing the difficulty of assembly and improving assembly efficiency.

[0023] In a third aspect, an embodiment of the present application provides a cooking utensil, comprising: a container body and a accommodating cover, wherein the container body has a accommodating cavity; the container cover can cover the container body, and in a first state, the outer end portion is located inside the container body, and in a second state, at least part of the structure of the outer end portion is located outside the container body, so that the accommodating cavity is connected to the outside through the first groove.

[0024] In this embodiment, when the container cover is closed on the container body, the pressure in the container body of the cooking utensil gradually increases during the cooking process, so that the cooking container has at least a first state and a second state. In the first state, the pressure in the cooking utensil is relatively small, and the sealing portion of the sealing ring of the container cover abuts against the container body, thereby sealing the opening of the container body through the sealing ring. At this time, the outer end of the sealing ring is located in the container body, and the steam in the cooking utensil cannot be discharged, so that the pressure in the cooking utensil is relatively high, which is convenient for quickly cooking the food. When the pressure inside the cooking utensil is relatively high, under the action of the air pressure, the sealing ring is elastically deformed, so that at least part of the structure of the outer end of the sealing ring is located outside the container body. At this time, a part of the first groove of the sealing ring is located inside the cooking utensil, and a part is located outside the cooking utensil, so that the inside of the cooking utensil is connected to the external environment through the first groove, so that the cooking utensil is in the second state, and the steam in the cooking utensil can be quickly discharged from the first groove, so as to achieve rapid pressure relief of the cooking utensil, reduce the safety hazard caused by excessive pressure in the cooking utensil, improve the safety of the cooking utensil, and reduce the exhaust noise.

[0056] The present application embodiment provides a sealing ring 12 of a cooking utensil, wherein: Figure 4 and Figure 5 As shown, the sealing ring 12 includes a connecting portion 123 and a sealing portion 124, the sealing portion 124 has an inner end portion 126 and an outer end portion 121 which are arranged opposite to each other along the radial direction of the sealing ring 12, the inner end portion 126 is connected to the connecting portion 123, at least the sealing portion 124 can be elastically deformed, and a first groove 122 is arranged on the inner wall of the sealing portion 124, and the first groove 122 passes through the inner end portion 126 and the outer end portion 121. When the container cover 1 with the sealing ring 12 installed is covered on the container body 2, the inner wall of the sealing portion 124 refers to the wall surface facing the inside of the cooking utensil.

[0057] In this embodiment, the sealing ring 12 has a connecting portion 123, which can facilitate the assembly of the sealing ring 12 and improve the connection reliability of the sealing ring 12. The sealing ring 12 also has a sealing portion 124, and at least the sealing portion 124 can be elastically deformed, so that the sealing portion 124 can switch its state in different use environments, thereby improving the applicability of the sealing ring 12. At the same time, a first groove 122 is provided on the inner wall of the sealing portion 124, which passes through the inner end 126 and the outer end 121, and the first groove 122 can be used for exhaust when the internal pressure of the cooking utensil is too high.

[0058] The present application also provides a container cover, such as Figure 1 and Figure 2 As shown, the container cover 1 includes a cover body 11 and a sealing ring 12 . The cover body 11 has a mounting groove 111 , and the sealing ring 12 is mounted in the mounting groove 111 .

[0059] In this embodiment, when the sealing ring 12 is installed on the cover body 11, the cover body 11 is provided with an installation groove 111, so that the connection portion 123 of the sealing ring 12 can be installed in the installation groove 111, thereby improving the connection reliability between the sealing ring 12 and the cover body 11, avoiding the phenomenon of the sealing ring 12 falling off during the transportation or use of the container cover 1, and improving the safety of the container cover 1. At the same time, the sealing portion 124 of the sealing ring 12 can be elastically deformed, so that the container cover 1 has at least a first state and a second state, the first state is a sealing state, and the second state is a pressure relief state, that is, the sealing ring 12 enables the container cover 1 to have at least a sealing state and a pressure relief state to meet the user's use requirements. The first groove 122 of the sealing ring 12 runs through the inner end 126 and the outer end 121 of the sealing ring 12. When the sealing ring 12 is in the second state, the first groove 122 connects the inside of the container cover 1 with the outside, thereby ensuring that the container cover 1 can be exhausted through the first groove 122 in the second state.

[0060] In this embodiment, the radial direction of the container cover 1 may be the same as the radial direction of the sealing ring 12 , and the height direction of the container cover 1 may be the same as the height direction of the sealing ring 12 .

[0061] The present application also provides a cooking utensil, which includes the above-mentioned container cover 1 and container body 2, wherein the container cover 1 can be covered on the container body 2. When the container cover 1 is covered on the container body 2, the pressure in the container body 2 of the cooking utensil gradually increases during the cooking process. Figure 1 and Figure 2 In the first state shown, the pressure inside the cooking utensil is relatively low, and the sealing portion 124 of the sealing ring 12 of the container cover 1 abuts against the container body 2, thereby sealing the opening of the container body 2 through the sealing ring 12. At this time, the outer end 121 of the sealing ring 12 is located inside the container body 2, and the steam inside the cooking utensil cannot be discharged, so that the pressure inside the cooking utensil is relatively high, which facilitates the rapid cooking of the food. Figure 3 As shown in FIG. 1 , when the pressure inside the cooking utensil is high, the sealing ring 12 is elastically deformed under the action of the air pressure, so that at least part of the structure of the outer end 121 of the sealing ring 12 is located outside the container body 2. At this time, part of the first groove 122 of the sealing ring 12 is located inside the cooking utensil, and part of it is located outside the cooking utensil, so that the inside of the cooking utensil is connected to the external environment through the first groove 122, so that the cooking utensil is in a state as shown in FIG. Figure 3 In the second state shown, the steam in the cooking utensil can be quickly discharged from the first groove 122, thereby achieving rapid pressure relief of the cooking utensil, reducing the potential safety hazard caused by excessive pressure in the cooking utensil, improving the safety of the cooking utensil, and reducing exhaust noise.

[0062] In a specific embodiment, Figure 2As shown, the container cover 1 has a first contact portion 112, and along the radial direction of the container cover 1, the first contact portion 112 is located outside the sealing ring 12, and the container body 2 may include a second contact portion 22 and a third contact portion 23, the second contact portion 22 is the side wall of the opening of the container body 2, and along the radial direction of the container body 2 (the radial direction of the container body 2 may be the same as the radial direction of the container cover 1), the third contact portion 23 is located outside the second contact portion 22. Figure 2 As shown, when the cooking utensil is in the first state, the sealing portion 124 of the sealing ring 12 of the container cover 1 abuts against the second contact portion 22, thereby sealing the opening of the container body 2 through the sealing portion 124 of the sealing ring 12. In the radial direction of the container cover 1, the first contact portion 112 is located outside the third contact portion 23, and there may be a gap between the two. When the pressure in the cooking utensil rises to the point where the sealing ring 12 is elastically deformed, the sealing portion 124 of the sealing ring 12 is squeezed into the gap between the first contact portion 112 and the third contact portion 23 under the action of the pressure. At this time, the first groove 122 of the sealing portion 124 communicates the gap with the interior of the cooking utensil to achieve pressure relief.

[0063] In a specific embodiment, the connection portion 123 and the installation groove 111 can be interference fit or snap-fit, so that the connection between the connection portion 123 and the installation groove 111 is more reliable, avoiding the sealing ring 12 from falling off during use or transportation, and can reduce assembly difficulty and improve assembly efficiency.

[0064] In a specific embodiment, Figure 3 and Figure 5 As shown, the sealing portion 124 may be provided with a plurality of first grooves 122 spaced apart along the circumference of the sealing ring 12 , and the plurality of first grooves 122 are evenly distributed.

[0065] In this embodiment, when the cooking appliance is in the second state, part of the structure of the sealing ring 12 will be elastically deformed under the action of pressure, so that at least part of the structure of the sealing ring 12 is located between the first contact portion 112 and the third contact portion 23, so that the gas in the accommodating cavity 21 can be quickly discharged through the first groove 122. When a plurality of first grooves 122 are arranged on the sealing portion 124 and are evenly distributed at intervals, when any position of the sealing ring 12 is squeezed out to be located between the first contact portion 112 and the third contact portion 23, the sealing portion 124 of the sealing ring 12 of this part can communicate with the accommodating cavity 21 and the outside through the first groove 122, so that the gas in the accommodating cavity 21 can be quickly discharged, thereby ensuring the pressure relief rate of the cooking appliance.

[0066] In a specific embodiment, the distance between adjacent first grooves 122 is 2.5 mm-3.5 mm, and / or the width of the first groove 122 is 1.8 mm-2.2 mm. For example, the distance between adjacent first grooves 122 may be 2.5 mm, 3.0 mm, 3.5 mm, etc., and / or the width of the first groove 122 may be 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, etc.

[0067] In this embodiment, the distance between adjacent first grooves 122 should not be too large or too small. When it is too large, the sealing ring 12 located between the third contact portion 23 and the first contact portion 112 in the second state will not be provided with the first groove 122 or the number of the first grooves 122 will be too small, affecting the pressure relief efficiency of the cooking utensil. When it is too small, the overall strength and rigidity of the sealing ring 12 will decrease, affecting the sealing reliability of the cooking utensil in the first state. In this embodiment, when the distance between adjacent first grooves 122 is 2.5mm-3.5mm, the sealing reliability of the cooking utensil in the first state is high, and the pressure relief can be quickly released in the second state.

[0068] The width of the first groove 122 should not be too large or too small. If it is too large, the overall strength and rigidity of the sealing ring 12 will decrease, affecting the sealing reliability of the cooking appliance in the first state. If it is too small, the flow cross-sectional area of ​​the first groove 122 will be too small, making the exhaust volume of the first groove 122 too small, affecting the pressure relief rate of the cooking appliance. In this embodiment, when the width of the first groove 122 is 1.8 mm-2.2 mm, the sealing reliability of the cooking appliance in the first state is high, and the pressure relief can be quickly released in the second state.

[0069] In a specific embodiment, Figure 6 As shown, the sealing portion 124 may include a main body 124a and a deformation section 124b, the deformation section 124b connects the main body 124a and the connecting portion 123, and the thickness of the deformation section 124b is smaller than the thickness of the main body 124a.

[0070] In this embodiment, since the thickness of the deformable section 124b of the sealing portion 124 is smaller than the thickness of the main body 124a, the deformable section 124b is more easily deformed when the sealing portion 124 is subjected to external force. Figure 3 and Figure 6As shown, when the pressure in the cooking utensil is relatively high, the deformation section 124b undergoes relatively large elastic deformation under the action of the pressure, that is, the deformation section 124b deforms radially outwardly along the container cover 1 under the action of the pressure, so that the main body 124a of the sealing portion 124 is located between the first contact portion 112 and the third contact portion 23, so that at least part of the structure of the sealing portion 124 is squeezed out, and then the first groove 122 provided on the sealing portion 124 is connected to the outside, so that the gas in the cooking utensil can be discharged through the first groove 122 on the sealing portion 124. In this embodiment, by providing the deformation section 124b with a relatively small thickness, at least part of the structure of the sealing portion 124 is more easily squeezed out under the action of the pressure, thereby further realizing the rapid exhaust of the cooking utensil.

[0071] In a specific embodiment, Figure 6 As shown, the body 124 a may be provided with a second groove 125 on a side facing away from the first groove 122 .

[0072] In this embodiment, Figure 2 and Figure 6 As shown, when the cooking appliance is in the first state, along the height direction X of the container cover 1, the main body 124a on the sealing portion 124 abuts against the second contact portion 22. By providing the second groove 125 on the side of the main body 124a away from the first groove 122, the contact position between the main body 124a and the second contact portion 22 is an arc, which can increase the contact area between the main body 124a and the second contact portion 22, thereby improving the sealing effect of the sealing ring 12. Figure 3 and Figure 6 As shown, when the cooking utensil is in the second state, the main body 124a is located between the first contact portion 112 and the third contact portion 23. By setting a second groove 125 that is away from the first groove 122, when the pressure is relatively high, the main body 124a is deformed radially along the container cover 1 toward one side of the second groove 125, thereby increasing the flow cross-sectional area of ​​the first groove 122, increasing the exhaust volume of the first groove 122, and thereby increasing the pressure relief rate.

[0073] In a specific embodiment, Figure 5 As shown, along the height direction X of the container cover 1 , both ends of the connection portion 123 may be connected to a sealing portion 124 , and the two sealing portions 124 are symmetrical with respect to the connection portion 123 .

[0074] In this embodiment, by providing two sealing portions 124 symmetrical to the connecting portion 123, when the cooking utensil is in the first state, the two sealing portions 124 are respectively in contact with the cover body 11 and the container body 2, thereby preventing gas from leaking between the container cover 1 and the sealing ring 12, and between the container body 2 and the sealing ring 12, and can further improve the sealing effect of the sealing ring 12 on the cooking utensil. At the same time, the sealing ring 12 in this embodiment is a symmetrical structure, and when the sealing ring 12 is installed on the cover body 11, the installation direction of the sealing ring 12 is not limited, thereby reducing the difficulty of assembly, and no additional error-proofing device for the sealing ring 12 is required during the assembly process, which can simplify the assembly steps and reduce costs.

[0075] In the above embodiments, Figure 3 and Figure 6 As shown, the outer end portion 121 is protruded relative to the sealing portion 124 along the height direction X of the container cover 1 .

[0076] In this embodiment, when the cooking utensil is in the second state, at least part of the structure of the sealing portion 124 is located between the first contact portion 112 and the third contact portion 23. At this time, when the outer end portion 121 of the sealing portion 124 protrudes along the height direction X of the container cover 1, the outer end portion 121 can abut against the third contact portion 23 of the container body 2, thereby supporting the sealing ring 12, improving the reliability of the container cover 1 covering the container body 2, and preventing the bottom wall of the first groove 122 from abutting against the third contact portion 23 to cause the first groove 122 to be blocked, so that the cooking utensil can exhaust air through the first groove 122.

[0077] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. 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.
