[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0049] As Figures 1 to 18As shown, the embodiment of the present application provides a cooking utensil, which comprises a cover 10 and a pot body 20, the cover 10 is provided with a first buckling part 11, the pot body 20 comprises a shell 21 and an inner pot 22 arranged in the shell 21, and the cover 10 is arranged on the inner pot 22 in an openable and closable manner. Wherein, the upper end of the shell 21 is provided with a pressure bearing part 30, the pressure bearing part 30 comprises a first pressure bearing section 31 and a second pressure bearing section 32, the first pressure bearing section 31 is in a ring structure, the first pressure bearing section 31 is arranged at the upper end of the shell 21, and the upper end of the inner pot 22 is arranged on the first pressure bearing section 31, and the outer edge of the first pressure bearing section 31 is provided with a second buckling part 311 capable of buckling with the first buckling part 11, the second pressure bearing section 32 is in a cylindrical structure, the upper end of the second pressure bearing section 32 is connected with the inner edge of the first pressure bearing section 31, and the lower end of the second pressure bearing section 32 extends into the shell 21 downward.

[0050] By arranging the pressure bearing part 30 at the upper end of the shell 21, the first pressure bearing section 31 of the pressure bearing part 30 is arranged at the upper end of the shell 21, the upper end of the inner pot 22 is arranged on the first pressure bearing section 31, and the outer edge of the first pressure bearing section 31 is provided with the second buckling part 311 capable of buckling with the first buckling part 11 of the cover 10, so that the pressure is transmitted to the first pressure bearing section 31 after the inner pot 22 is pressed, the upper end of the shell 21 supports the first pressure bearing section 31, and the inner pot 22 does not need to be supported by the heat preservation cover, and since the pressure bearing part 30 further comprises the second pressure bearing section 32, the pressure can be transmitted to the second pressure bearing section 32 after the first pressure bearing section 31 starts to bear pressure, the pressure bearing strength of the pressure bearing part 30 can be further improved, and the cost of the cooking utensil can be reduced.

[0051] It should be noted that since the upper end of the inner pot 22 can be arranged on the first pressure bearing section 31 of the pressure bearing part 30, the first pressure bearing section 31 is arranged at the upper end of the shell 21, and the pressure bearing strength can be improved, the top pressure bearing can be realized by using the pressure bearing part 30, so that the structural strength can be improved, the heat preservation cover can be cancelled, and the cost can be reduced.

[0052] As shown in the accompanying drawings, Figure 2 , Figure 3 and Figure 8As shown, the inner side wall of the shell 21 is provided with a limiting surface 211 and a relief surface 212 below the limiting surface 211, the limiting surface 211 protrudes inward in the radial direction of the shell 21 than the relief surface 212, the outer side wall of the second pressure receiving section 32 is in limiting cooperation with the limiting surface 211, and the lower end of the second pressure receiving section 32 is higher than the lower end of the relief surface 212. With the above structure, after the first pressure receiving section 31 starts to receive pressure, the first pressure receiving section 31 can transmit the pressure to the second pressure receiving section 32, because the outer side wall of the second pressure receiving section 32 is in limiting cooperation with the limiting surface 211 of the inner side wall of the shell 21, so that the lower end of the second pressure receiving section 32 has a tendency to deform outward, at this time the second pressure receiving section 32 can be relieved by the relief surface 212 on the inner side wall of the shell 21, so that the second pressure receiving section 32 deforms smoothly. Therefore, under the cooperation of the first pressure receiving section 31 and the second pressure receiving section 32, the pressure receiving capacity of the pressure receiving part 30 can be improved.

[0053] That is, by supporting the inner pot 22 on the pressure receiving part 30, the pressure of the inner pot 22 after being pressed is transmitted to the first pressure receiving section 31 through the pot rim, and the force is evenly transferred to the diameter of the ring-shaped body of the second pressure receiving section 32, the second pressure receiving section 32 has a certain height, so that when the pressure is transmitted to the second pressure receiving section 32, it is evenly supported by the ring-shaped body, as the pressure increases, the diameter of the ring-shaped body will also increase slightly due to the increase in pressure, the closer to the first pressure receiving section 31, the smaller the change in diameter, the farther away from the first pressure receiving section 31, the greater the change, in the process of force, the second pressure receiving section 32 deforms into a slightly tapered circular ring, the diameter becomes larger as it goes down from the connection with the first pressure receiving section 31, and the relief surface 212 of the shell 21 is used to avoid the second pressure receiving section 32 after the diameter increases, preventing the shell from deforming under stress after being pressed.

[0054] With the above structure, the second pressure receiving section 32 achieves the purpose of pressure receiving along the radial circumference, changes the direction of a part of the force to radial stress deformation, and is connected in the circumferential direction, so that the whole is stable under pressure. Moreover, in this way, the pressure receiving requirement of the heat preservation cover can be reduced, or the heat preservation cover can be cancelled.
