Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a sealing component, a sealing assembly, a valve body assembly, a cover assembly and a cooking utensil. Background Art

[0002] The sealing ring is generally made of natural rubber or synthetic rubber and has a certain degree of flexibility. The sealing ring can be placed on the shaft body and can achieve a seal between the shaft body and the hole body.

[0003] In the related art, the sealing ring is a sealing ring, and the side wall of the sealing ring can abut against the end wall of the hole body. However, due to the certain thickness of the sealing ring, the sealing ring cannot be effectively deformed when abutting against the end wall of the hole body, and thus the sealing effect cannot be guaranteed. Utility Model Content

[0004] The main purpose of the present invention is to provide a sealing component, a sealing assembly, a valve body assembly, a cover assembly and a cooking utensil to solve the problem of poor sealing effect of the sealing ring in the related art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a sealing component is provided, including: a base portion; an annular lip portion connected to the outer periphery of the first end of the base portion; wherein, in the direction from the first end of the base portion to the second end of the base portion, the distance between the annular lip portion and the axis of the base portion gradually increases.

[0006] Using the technical solution of the present invention, the annular lip portion is connected to the outer periphery of the first end of the base portion, and the distance between the annular lip portion and the axis of the base portion gradually increases from the first end of the base portion to the second end of the base portion. Through the above-mentioned arrangement, the base portion can improve the overall structural strength and positional stability of the sealing component. The arrangement of the annular lip portion can achieve sealing, and when sealing, the annular lip portion is more likely to deform, that is, the annular lip portion can fit more closely with the sealed component, thereby achieving a better sealing effect. Therefore, the technical solution of the present application can effectively solve the problem of poor sealing effect of the sealing ring in the related art.

[0007] Furthermore, the area surrounding the outer periphery of the annular lip is located between the first end and the second end of the base. This arrangement can prevent the annular lip from being too large and from being easily deformed. In other words, it can ensure the structural strength of the annular lip while ensuring that the annular lip has a certain degree of deformation, thereby ensuring a good sealing effect.

[0008] Furthermore, the angle between the tangent line of the surface of the annular lip away from the base and the center line of the base is less than 90° and greater than or equal to 45°. The above arrangement can achieve a better sealing effect of the annular lip.

[0009] Furthermore, the area a of the base projected on the predetermined surface and the area b of the annular lip projected on the predetermined surface satisfy the following relationship: 0.1 ≤ a / b ≤ 0.5, and / or both the base and the annular lip are made of flexible materials. This arrangement ensures the structural strength of the annular lip and a relatively stable position of the base. Furthermore, since both the base and the annular lip are made of flexible materials, they can deform to a certain extent, thereby ensuring a tight fit between the annular lip and the sealed component.

[0010] According to a second aspect of the present invention, a sealing assembly is provided, comprising: a connecting rod having a mounting portion disposed thereon; and a sealing component mounted on the mounting portion, the sealing component being the aforementioned sealing component. The aforementioned sealing component has a good sealing effect, so that when the sealing component is mounted on the connecting rod, the connecting rod can be effectively sealed. Therefore, the sealing assembly having the aforementioned sealing component has a good sealing effect.

[0011] Furthermore, the mounting portion includes an annular groove and a first stopper and a second stopper disposed on either side of the annular groove. The sealing component is mounted within the annular groove and positioned between the first stopper and the second stopper. The provision of the first stopper and the second stopper can effectively limit the position of the sealing component, thereby further stabilizing the position of the sealing component.

[0012] Furthermore, the sealing assembly further comprises a sealing ring which is mounted on the connecting rod and spaced apart from the sealing component. The provision of the sealing ring can achieve sealing of other positions.

[0013] According to a third aspect of the present invention, a valve body assembly is provided, comprising a sealing assembly, wherein the sealing assembly is the above-mentioned sealing assembly. The above-mentioned sealing assembly has a good sealing effect, and therefore the valve body assembly having the above-mentioned sealing assembly also has the above-mentioned effect.

[0014] According to a fourth aspect of the present invention, a cover assembly is provided, comprising a valve assembly, wherein the valve assembly is the valve assembly described above. The sealing assembly of the valve assembly described above has a good sealing effect and can prevent air or liquid leakage. Therefore, the cover assembly having the valve assembly described above also has the above advantages.

[0015] According to a fifth aspect of the present invention, a cooking utensil is provided, comprising a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The valve assembly in the above-mentioned cover assembly has a good sealing effect, so the cooking utensil having the above-mentioned cover assembly also has the above-mentioned effect.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the sealing component includes a base portion 10 and an annular lip portion 20. The annular lip portion 20 is connected to the outer periphery of the first end of the base portion 10. The distance between the annular lip portion 20 and the axis of the base portion 10 gradually increases from the first end to the second end of the base portion 10.

[0029] Using the technical solution of this embodiment, the annular lip portion 20 is connected to the outer periphery of the first end of the base portion 10. The distance between the annular lip portion 20 and the axis of the base portion 10 gradually increases from the first end of the base portion 10 to the second end of the base portion 10. Through this arrangement, the base portion 10 can improve the overall structural strength and positional stability of the sealing component. The provision of the annular lip portion 20 can achieve sealing. During sealing, the annular lip portion 20 is more likely to deform, that is, the annular lip portion 20 can fit more closely with the sealed component, thereby achieving a better sealing effect. Therefore, the technical solution of this embodiment can effectively solve the problem of poor sealing effect of the sealing ring in the related art.

[0030] Preferably, the base portion 10 is a cylinder. Of course, in other embodiments, the base portion may also be a cone, a frustum, a rectangle or other shapes.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the area surrounding the outer periphery of the annular lip portion 20 is located between the first end and the second end of the base portion 10. The above arrangement can prevent the annular lip portion 20 from being too large and prevent the annular lip portion 20 from being easily deformed. In other words, it can ensure the structural strength of the annular lip portion 20 while ensuring that the annular lip portion 20 has a certain degree of deformation, thereby ensuring a good sealing effect.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the angle between the tangent line of the surface of the annular lip portion 20 away from the base portion 10 and the center line of the base portion 10 is less than 90° and greater than or equal to 45°. The above arrangement can make the annular lip portion 20 have a better sealing effect.

[0033] It should be noted that the base portion 10 has a regular structure, and the center line of the base portion 10 refers to the axis of the base portion.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the area a projected by the base portion 10 on the predetermined surface and the area b projected by the annular lip portion 20 on the predetermined surface satisfy the relationship: 0.1 ≤ a / b ≤ 0.5. Both the base portion 10 and the annular lip portion 20 are made of flexible materials. This arrangement ensures the structural strength of the annular lip portion 20 and a relatively stable position of the base portion 10. Furthermore, since both the base portion 10 and the annular lip portion 20 are made of flexible materials, they can deform to a certain extent, thereby ensuring a tight fit between the annular lip portion 20 and the sealed component.

[0035] Specifically, in this embodiment, a / b=0.5. Of course, in embodiments not shown in the figures, a / b may also be 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45 or other ratios.

[0036] Preferably, the flexible material is silicone rubber. Of course, the flexible material can also be fluororubber, silicone rubber, polyurethane rubber, nitrile rubber or other materials.

[0037] According to a second aspect of the present application, a sealing assembly is provided, such as Figure 3 and Figure 4As shown, the sealing assembly of this embodiment includes a connecting rod 30 and a sealing component. The connecting rod 30 is provided with a mounting portion 31. The sealing component is mounted on the mounting portion 31. The sealing component is the aforementioned sealing component. The aforementioned sealing component provides a good sealing effect. Therefore, once the sealing component is installed on the connecting rod 30, the connecting rod 30 can be effectively sealed. Therefore, the sealing assembly with the aforementioned sealing component provides a good sealing effect.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, the mounting portion 31 includes an annular groove 311 and a first stopper 312 and a second stopper 313 provided on either side of the annular groove 311. The sealing component is mounted in the annular groove 311 and is located between the first stopper 312 and the second stopper 313. The provision of the first stopper 312 and the second stopper 313 can effectively limit the position of the sealing component, thereby making the position of the sealing component more stable.

[0039] Specifically, the first stopper 312, the second stopper 313, and the base 10 are all circular in shape. The diameter of the first stopper 312 is larger than that of the second stopper 313, which in turn is larger than that of the base 10, which in turn is larger than that of the second stopper 313. Through this arrangement, the second stopper 313 can avoid affecting the deformation of the annular lip portion 20, and the larger diameter of the first stopper 312 increases the contact area between the first stopper 312 and the base 10, thereby further stabilizing the position of the base 10.

[0040] like Figure 3 and Figure 4 As shown, in this embodiment, the second stopper 313 has a tapered surface on the side away from the first stopper 312. The distance between the tapered surface and the axis of the connecting rod 30 gradually increases from the second stopper 313 to the first stopper 312. As the connecting rod 30 moves, the tapered surface guides the mating hole. Specifically, the distance between the centerline of the tapered surface and the axis of the hole gradually decreases, thereby adjusting the positional correspondence between the connecting rod 30 and the hole, allowing the sealing component to effectively seal the hole.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, the sealing assembly further includes a sealing ring 40, which is mounted on the connecting rod 30 and spaced apart from the sealing component. The provision of the sealing ring 40 can achieve sealing at other locations.

[0042] The connecting rod 30 is also provided with a third stopper and a fourth stopper, which are spaced apart on the connecting rod 30. The sealing ring 40 is disposed between the third and fourth stoppers. The fourth stopper is located between the first and fourth stoppers 312 and 313. There is a space between the third and second stoppers 313. The third and fourth stoppers limit the position of the sealing ring 40, thereby further stabilizing the position of the sealing ring 40.

[0043] A tapered surface is provided on the side of the fourth stopper away from the third stopper. The distance between the tapered surface and the axis of the connecting rod 30 gradually increases from the fourth stopper to the third stopper. The tapered surface further enhances the guiding effect, ensuring a stable relative position between the connecting rod 30 and the hole when engaged with the tapered surface.

[0044] According to a third aspect of the present application, a valve body assembly is provided, such as Figure 6 As shown, the valve body assembly of this embodiment includes a sealing assembly, which is the above-mentioned sealing assembly. The above-mentioned sealing assembly has a good sealing effect, so the valve body assembly with the above-mentioned sealing assembly also has the above-mentioned effect.

[0045] The valve body assembly also includes a valve body.

[0046] The valve body has a valve cavity, an inlet communicating with the valve cavity, and a first outlet and a second outlet communicating with the valve cavity.

[0047] The valve body is provided with a mounting hole, and the valve body assembly also includes a mounting tube, which is installed in the mounting hole. The interior of the mounting tube forms a second outlet, and the sealing ring 40 can block the second outlet or avoid the second outlet. The sealing ring 40 is installed into the interior of the valve body through the mounting hole, and the mounting tube is then installed in the mounting hole. In this way, the sealing ring 40 can block or avoid the second outlet.

[0048] The mounting cylinder includes a cylinder body and a connecting portion connected to a first end of the cylinder body, the connecting portion being connected between the first end of the cylinder body and the valve body, and the second end of the cylinder body extending into the valve cavity and cooperating with the sealing ring 40. The provision of the connecting portion can make the connection between the mounting cylinder and the valve body more stable.

[0049] According to a fourth aspect of the present application, a cover assembly is provided, comprising a valve assembly, wherein the valve assembly is the valve assembly described above. The sealing assembly of the valve assembly described above has a good sealing effect and can prevent air or liquid leakage. Therefore, the cover assembly having the valve assembly described above also has the above advantages.

[0050] According to a fifth aspect of the present application, a cooking utensil is provided, comprising a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The valve assembly in the above-mentioned cover assembly has a good sealing effect, so the cooking utensil having the above-mentioned cover assembly also has the above-mentioned effect.

[0051] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
