The first protrusion structure 212 and the second protrusion structure 213 make contact between the connection part 210 and the insulation cover 100 more tight, thereby improving sealing effect.
Preferably, as shown in fig. 5, a positioning portion 214 is further disposed on the connecting portion 210, and the positioning portion 214 cooperates with the seal ring positioning structure 303 on the cover bracket 300 to position the installation of the seal ring 200. In this embodiment, the positioning portion 214 is a protruding structure formed on the connecting portion 210 towards the radial outer side thereof, and when installed, the positioning portion 214 is located in the seal ring positioning structure 303, and performs positioning and foolproof functions, so as to ensure that the seal ring 200 and the cover plate bracket 300 have a unique relative positional relationship.
The sealing part 220 is used for forming sealing contact with the pot body, the sealing part 220 comprises a first part 221 and a second part 222, and the first part 221 and the second part 222 are connected. The first portion 221 extends radially outward of the sealing portion 220 for contact with the rim of the opening; the second portion 220 extends along the axial direction of the sealing portion 220 in a direction away from the connecting portion 210, so as to form a sealing fit with the inner wall of the pot, the first portion 221 is connected with the second portion 222, and has an inverted L-shaped cross section, and the intersecting position of the first portion 221 and the second portion 222 is connected with the connecting portion 210, so that in order to improve the sealing effect between the sealing portion 220 and the pot body, a part of each of the first portion 221 and the second portion 222 is connected with the connecting portion 210, thereby improving the strength of the connecting portion, and enabling the connecting portion to apply a larger pressing force to the pot body, so as to obtain a better sealing effect. When the cover plate assembly is covered on the pot body, the first part 221 is pressed on the edge of the pot opening, and the second part 222 extends into the pot body and is in sealing contact with the inner wall of the pot body. Preferably, a plurality of protruding structures are formed on the surface of the first portion 221 contacting the rim of the pot, and the protruding structures play a supporting role when the first portion 211 contacts the rim of the pot, so that the second portion 222 can be turned over or turned over, so that the second portion 222 can be pressed against the inner wall of the pot, thereby improving the sealing effect.
The sealing part 220 is further provided with a venting part which does not vent under normal conditions, and when the venting hole 111 on the heat-insulating cover plate 100 cannot vent normally to cause the pressure in the pot to be too high, the venting part can vent the gas in the pot, for example, when the pressure reaches or exceeds a preset pressure, the venting part starts to vent, and when the pressure is lower than the preset pressure, the venting part does not vent any more, preferably, the preset pressure is 35-45KPa, preferably 40KPa.
Preferably, the thickness of the partial area of the sealing part 220 is smaller, for example, the thickness of the first part 221 and/or the second part 222 can be reduced, so that the pressing force between the partial area and the pot body is smaller, and when the pressure value in the pot body is higher than the normal pressure, the high-pressure gas can separate the partial area of the sealing part 220 with smaller thickness from the pot body to form an exhaust channel for exhausting gas, so that the pressure in the pot is reduced. When the pressure in the cooker is restored to a normal value, the sealing part 220 and the cooker body can restore the sealing, and the gas can not flow out from the sealing part. Alternatively, the thickness of the connection portion between the sealing portion 220 and the connection portion 210 may be reduced, where the thickness is greater than the thickness of the first portion 221 and the second portion 222, so that the reduction of the thickness does not greatly affect the overall strength of the sealing portion 220. Further, as shown in fig. 7, the first portion 221 is not directly connected to the connection portion 210, the connection portion 210 is connected to the second portion 222, the second portion 222 is connected to the first portion 221, and a gap is formed between the first portion 221 and the connection portion 210, thereby reducing the thickness of the connection portion 210 between the sealing portion 220 and the connection portion 210. This allows the high pressure gas to push the second portion 222 and the first portion 221 to move in a direction approaching the connection portion 210 when the pressure in the pot body is excessively high, thereby forming an exhaust passage for gas discharge.
The smaller thickness of the sealing part 220 forms the exhaust part, preferably, the exhaust part is provided with one exhaust part, and further, the exhaust part is located at the connection position of the cover body and the pot body during installation, that is, the exhaust part is located at the rear side of the cooking device, so as to ensure that when the exhaust part is used for exhausting, gas is exhausted towards the rear side of the pot body, and the condition that the forward exhaust of the gas can cause scalding to a user is avoided.
As shown in fig. 8, the cover plate assembly 10 is arranged on the cover body of the cooking appliance, and when the cover body is covered on the pot body 10, the cover plate assembly 10 is in sealing contact with the pot body 20, so that certain pressure can be provided in the pot body 20. Preferably, the cooking vessel comprises a pressure cooker, an electric cooker and the like.
According to the cover plate assembly provided by the invention, the exhaust part is arranged on the sealing ring, so that the exhaust part can exhaust the pressure in the pot when the pressure is too high, the cover body can be prevented from being washed away or other parts can be prevented from being damaged when the pressure is too high in China, and the safety of the cooking utensil is improved.
It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.
It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
