Description

Sealing ring structure, cover body assembly and cooking utensil

Technical Field

The utility model relates to the technical field of small household appliances, in particular to a sealing ring structure, a cover body assembly and a cooking utensil.

Background

In the related art, in the process of cooking food by using the electric pressure cooker, higher pressure can be provided in the cooking cavity, so that water in the cooking cavity can reach higher temperature to realize the purpose of accelerating the cooking of the food, and therefore, the electric pressure cooker is widely applied.

In order to ensure the pressure in the cooking cavity, a sealing ring structure needs to be arranged between the cover body and the pot body of the pressure cooking appliance, and when the cover opening operation is carried out after the cooking is finished, the lower sealing lip edge of the sealing ring structure needs to slide upwards along the inner wall surface of the pot body until the cover opening operation and the pot body are completely separated. However, because there is a vacuum cavity between the lower sealing lip and the pan body or grease viscosity is generated between the lower sealing lip and the pan body when grease enters in the cooking process, a large force is required to separate the lower sealing lip from the pan body, that is, a sucking phenomenon occurs, so that the operation experience of a user is poor.

The utility model mainly aims to provide a sealing ring structure, a cover body assembly and a cooking utensil, so as to solve the problem of poor operation experience when a user uncovers a cover in the related art.

In order to achieve the above object, according to one aspect of the present utility model, there is provided a seal ring structure comprising: an annular body portion; the pot mouth sealing lip is connected to the inner side of the annular main body part and comprises a supporting lip and a sealing lip, the supporting lip is connected with the annular main body part and extends downwards, the sealing lip is connected to the lower end of the supporting lip and extends upwards, and the sealing lip is positioned on the outer side of the supporting lip.

By applying the technical scheme of the utility model, the pot mouth sealing lip can be matched with the pot mouth of the pot body in a sealing way. Specifically, the pot mouth sealing lip comprises a supporting lip and a sealing lip, wherein the sealing lip can be pressed on the wall surface of the pot mouth position of the pot body and is in sealing fit with the wall surface of the pot mouth position of the pot body in the cooking process, and the sealing lip is connected with the annular main body part through the supporting lip; when the cover opening operation is performed after cooking is completed, the supporting lip edge moves upwards along with the annular main body part and the cover body, the lower end of the supporting lip edge pulls the sealing lip edge to turn upwards, and compared with the separation mode in the related art that the sealing lip edge slides upwards to be separated from the pot opening, the force required by the separation mode that the sealing lip edge is gradually separated from the pot opening from bottom to top is small by pulling the sealing lip edge in the embodiment, so that the phenomenon of sucking the pot can be avoided, and the operation experience of a user during cover opening is improved. Therefore, the technical scheme of the application can effectively solve the problem that the operation experience is poor when a user uncovers the cover in the related technology.

Further, the port sealing lip further includes an arcuate connecting lip connected between the support lip and the sealing lip. The arc-shaped connecting lip edge is used for connecting the supporting lip edge and the sealing lip edge, so that the integral structure of the sealing lip edge of the pot mouth is simpler and easy to process and manufacture.

Specifically, the seal ring structure of the present embodiment includes an annular body portion 10 and a port seal lip 20, wherein the port seal lip 20 is connected to the inner side of the annular body portion 10, the port seal lip 20 includes a support lip 21 and a seal lip 22, the support lip 21 is connected to the annular body portion 10 and extends downward, the seal lip 22 is connected to the lower end of the support lip 21 and extends upward, and the seal lip 22 is located on the outer side of the support lip 21.

By applying the technical scheme of the embodiment, the pot mouth sealing lip 20 can be matched with the pot mouth of the pot body 60 in a sealing way. Specifically, the port sealing lip 20 includes a supporting lip 21 and a sealing lip 22, wherein the sealing lip 22 can be pressed against and sealingly engaged with the wall surface of the port position of the pot 60 during cooking, and the sealing lip 22 is connected with the annular body portion 10 through the supporting lip 21; when the lid opening operation is performed after the cooking is completed, the supporting lip edge 21 moves upwards along with the annular main body 10 and the lid body 40, and the lower end of the supporting lip edge 21 pulls the sealing lip edge 22 to turn upwards, compared with the separation mode in the related art that the sealing lip edge slides upwards to separate from the pot opening, in the embodiment, the force required by the separation mode that the sealing lip edge 22 is pulled to gradually separate from the pot opening from bottom to top is small, so that the phenomenon of sucking the pot can be avoided, and the operation experience of a user in the lid opening process is improved. Therefore, the technical scheme of the embodiment can effectively solve the problem of poor operation experience when a user uncaps in the related technology.

As shown in fig. 1, in describing embodiments of the present application, the "inner" or "inboard" is used to refer to the side that is closer to the axial centerline of the seal ring structure, and the "outer" or "outboard" is used to refer to the side that is farther from the axial centerline of the seal ring structure.
