[0003] However, during the exhaust process, especially during the exhaust and pressure reduction process after the pressure cooking is finished, due to the large difference between the internal and external air pressure, the gas in the cooking cavity will be discharged with high kinetic energy, and then the gas may carry part of the food to the exhaust assembly on the pot cover, so that the food may block the exhaust hole, resulting in that the gas in the cooking cavity cannot be discharged through the exhaust hole, and the gas pressure in the pot abnormally increases or cannot be normally exhausted and depressurized.

[0004] Therefore, the cooking utensil is usually provided with a blocking prevention cover on the pot cover, which is fixed to the lower side of the pot cover and located in the cooking cavity, and the blocking prevention cover is provided with a gas passing opening, so that the gas in the cooking cavity can reach the exhaust hole through the gas passing opening and be discharged, and the food can be blocked outside the blocking prevention cover and cannot reach the exhaust hole on the pot cover. The blocking prevention cover needs to have good high temperature resistance because it directly contacts the cooking environment in the cooking cavity, so the blocking prevention cover is mostly made of metal and is fixed to the inner cover which is also made of metal.

[0005] Firstly, the blocking prevention cover and the inner cover are both made of metal and will slightly deform under high temperature, so that the connection between the two is prone to loosening and then shaking. In addition, after the blocking prevention cover and the inner cover are installed, the two are prone to wear at the connection, and the connection structure of the two will loosen and the connection strength will decrease over time.

[0006] In addition, because the blocking prevention cover is located in the cooking cavity during the cooking process, when the blocking prevention cover is detached from the inner cover, on the one hand, the temperature of the blocking prevention cover is high, which is inconvenient for the user to hold, and on the other hand, the steam and oil in the cooking cavity are prone to adhere to the surface of the blocking prevention cover, so that the user is prone to slipping when holding the blocking prevention cover, which makes the user unable to apply force well, and then the blocking prevention cover cannot be detached in time and is difficult to detach, and the dirt is prone to solidification and accumulation.

Meanwhile, anti-blocking cover 2 is fixed with heat insulation piece 3, anti-blocking cover 2 is fixed with heat insulation piece 3, connecting portion 31 of heat insulation piece 3 is fixed with inner pot, so that anti-blocking cover 2 is fixed on inner cover 1 through heat insulation piece 3, and there is no direct connection between anti-blocking cover 2 and inner cover 1, so that wear of the two is avoided, and service life is improved. And because the heat transfer performance of heat insulation piece 3 is poor, heat insulation piece 3 is not prone to deformation under high temperature, so that the connecting effect and stability with inner cover 1 can be maintained, the stable connection and position stability of anti-blocking cover 2 are maintained, and the possibility of shaking of anti-blocking cover 2 is reduced. Meanwhile, heat insulation piece 3 can be made of flexible material, so that the connection between connecting portion 31 and inner cover 1 is more flexible, and connecting portion 31 can be elastically deformed to ensure reliable connection with inner cover 1, to reduce installation difficulty and requirement for machining precision, and to improve the convenience of user installation.

[0052] In addition, when anti-blocking cover 2 is disassembled, the user can hold holding portion 32 protruding from anti-blocking cover 2 of heat insulation piece 3 to disassemble heat insulation piece 3 and anti-blocking cover 2 from inner cover 1.

In a preferred embodiment, inner cover 1 is fixed on cover 5 in a detachable manner. Because inner cover 1 directly contacts the environment in cooking cavity 6, inner cover 1 is convenient for the user to clean. Specifically, after the user disassembles inner cover 1, anti-blocking cover 2 can be further disassembled from inner cover 1, so that inner cover 1 and anti-blocking cover 2 are cleaned respectively. Alternatively, anti-blocking cover 2 can be directly disassembled from inner cover 1 without disassembling inner cover 1, to clean anti-blocking cover 2 alone.

[0054] It should be noted that the material of the heat insulation piece 3 is not limited, as long as its thermal conductivity is weaker than that of the anti-blocking cover 2. Preferably, the heat insulation piece 3 is made of an elastic material. As a preferred embodiment, the heat insulation piece 3 is made of silica gel. On the one hand, it has better heat resistance, and on the other hand, it can be fixed to the anti-blocking cover 2 and the inner cover 1 in more ways, for example, the heat insulation piece 3 can be fixed by interference fit, and no matter how it is fixed, after the fixing is completed, the heat insulation piece 3 is elastically deformed by extrusion, and the connection can also be sealed, thereby simultaneously playing a sealing role, saving the use of sealing elements and saving costs.

[0057] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 , the fixing portion 12 is located at the center of the inner cover 1, the fixing portion 12 has a downward protruding annular protruding rib 123, the first clamping structure 124 is a clamping protruding rib arranged on the outer peripheral side of the annular protruding rib 123, the connecting portion 31 is arranged on the outer peripheral side of the annular protruding rib 123, and the second clamping structure 311 is a clamping hook arranged on the inner wall of the connecting portion 31. The clamping hook and the clamping protruding rib are clamped and cooperated to realize fixation.

[0058] The clamping protruding rib can be discontinuous and arranged in multiple sections along the circumferential direction of the annular protruding rib 123, or it can be a complete circle to surround the annular protruding rib 123, which is not limited here.

[0059] As shown in Figure 6As shown, the annular protrusions 123 are spaced apart circumferentially by gaps, so that the annular protrusions 123 are segmented circumferentially, and the first clamping structure 124 is arranged on each segment of the annular protrusions 123, so that each segment of the annular protrusions 123 can be deformed to a certain extent, to facilitate the cooperation and disengagement of the first clamping structure 124 and the second clamping structure 311.

[0060] Of course, the connecting portion 31 and the fixing portion 12 can also be fixed by other means, such as threaded fixing, interference fit, etc., which are not limited herein.

[0061] Further, the present embodiment does not limit the assembly method of the fixing portion 12 and the inner cover 1. In one embodiment, the fixing portion 12 and the inner cover 1 are integrally formed, so that the connecting portion 31 is directly connected to the inner cover 1, which has better connection stability and can simplify the structure of the pot cover assembly. The fixing portion 12 is formed by a downward protruding rib at the center of the inner cover 1, and the first clamping structure 124 is further processed on the fixing portion 12 for cooperation with the connecting portion 31.

[0062] In another embodiment, as shown in Figure 1 , Figure 2 , Figure 6 , Figure 7 The fixing portion 12 and the inner cover 1 are separate structures. During installation, the fixing portion 12 is first clamped and fixed to the inner cover 1, and then the connecting portion 31 is fixed to the fixing portion 12 to indirectly connect the connecting portion 31 and the inner cover 1. This not only ensures the connection effect, but also reduces the processing difficulty of the inner cover 1. Meanwhile, the fixing portion 12 can be made of different materials from the inner cover 1, thereby saving the material of the inner cover 1 and achieving the purpose of cost saving.

[0063] Further, as shown in Figure 1 , Figure 6 , Figure 7 The inner cover 1 is provided with an opening, the fixing portion 12 has a fastening portion 121 above the inner cover 1, and a cooperation portion 122 extending through the opening to below the inner cover 1, and the first clamping structure 124 is arranged on the cooperation portion 122. The pot cover assembly further comprises a valve body fixing seat 4 fixed to the upper side of the inner cover 1, and the valve body fixing seat 4 clamps the fastening portion 121 with the inner cover 1.

[0064] As shown in Figure 7 The fastening portion 121 on the fixing portion 12 has a flange, which is located between the valve body fixing seat 4 and the inner cover 1 and is clamped by the two. Further, the valve body fixing seat 4, the fastening portion 121 and the inner cover 1 can be fastened and connected by fasteners such as rivets and screws to improve the connection stability. The cooperation portion 122 extends through the opening of the inner cover 1 to below the inner cover 1, for cooperation and fixation with the connecting portion 31.

[0065] Preferably, as shown inFigure 3 , Figure 5 As shown, the anti-blocking cover 2 is provided with an installation port 22, the connecting part 31 is installed in the installation port 22, and the outer periphery of the connecting part 31 is provided with a slot 312. The edge of the installation port 22 is located in the slot 312 so that the heat insulation component 3 is fixed to the anti-blocking cover 2.

[0066] The anti-clogging cover 2 is snapped into and fixed to the connecting part 31. After forming an integral component with the heat insulation part 3, it can be installed into the inner cover 1 together with the heat insulation part. The two are fixed by snapping, which makes the installation and disassembly of the two simpler. Users can easily separate the heat insulation part and the anti-clogging cover 2 and clean them separately to ensure that both are clean.

[0067] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the connecting part 31 surrounds the fixing part 12 of the inner cover 1. The outer wall of the connecting part 31 is provided with a groove 312 for fixing to the anti-blocking cover 2.

[0068] Preferably, such as Figure 1 , Figure 4 , Figure 5 As shown, the connecting part 31 is fixed to the bottom wall of the anti-blocking cover 2, and the gripping part 32 has a fixed end 321 connected to the connecting part 31 and a gripping end 322 extending downward at an angle. There is an accommodating gap 323 between the gripping end 322 and the anti-blocking cover 2.

[0069] The heat insulation part is fixed to the bottom wall of the anti-clogging cover 2, which makes it easier to fix to the inner cover 1. It also makes it easier for the grip end 322 to extend downward for the user to grip. The accommodating gap 323 between the grip end 322 and the anti-clogging cover 2 not only facilitates the heat dissipation of the anti-clogging cover 2 and prevents the grip end 322 from contacting the anti-clogging cover 2 and causing the temperature to rise, but also leaves space for the user to grip the grip end 322. The user can put their fingers into the accommodating space to grip the grip end 322 for a better user experience.

[0070] Preferably, such as Figure 3 As shown, the mounting port 22 is opened at the center of the bottom wall of the anti-blocking cover 2, and the heat insulation component 3 is fixed at the center of the bottom wall of the anti-blocking cover 2.

[0072] Preferably, the holding part 32 is a structure made of flexible material such as silica gel, the fixed end 321 is connected with the connecting part 31, and the holding end 322 naturally hangs down under the gravity of itself, so as to form a containing gap 323 between the holding end 322 and the bottom wall of the anti-blocking cover 2.

[0073] In a preferred embodiment, the heat insulation part 3 is a structure made of elastic material as a whole, so as to have good heat resistance, facilitate processing and cleaning, and be low in cost.

[0074] In another preferred embodiment, an outer side of the holding part 32 is sleeved with a heat insulation sleeve, so as to reduce the temperature rise of the holding part 32 held by the user and improve the holding experience of the user. Meanwhile, the heat insulation sleeve is provided, so that the thickness of the holding end 322 is increased, thereby further reducing the temperature rise of the holding end 322 and facilitating the user to hold. In the embodiment, the part of the heat insulation part 3 other than the holding part 32 can be made of flexible material or hard structure, which is not limited here.

[0075] Further, as shown in Figure 4 、 Figure 5 , an anti-skid pattern 34 is arranged on the outer surface of the holding part 32 or the heat insulation sleeve.

[0076] By arranging the anti-skid pattern 34 on the outer surface of the holding part 32 or the heat insulation sleeve, the friction force when the user holds can be increased, especially when the surface of the heat insulation part 3 is attached with steam or grease, the phenomenon of slipping when the user holds can be reduced, so that the user can easily remove the anti-blocking cover 2.
