In the inner cover of the pressure cooking appliance, the rotation stopping structure comprises a rotation stopping hole arranged on the clamping seat and a rotation stopping boss arranged on the connecting seat, and the rotation stopping boss is in non-circular fit with the rotation stopping hole.

In the inner cover of the pressure cooking appliance, the inner cover body is provided with an assembly hole, and the rotation stopping boss penetrates through the assembly hole and is in non-circular fit with the assembly hole so as to limit the relative rotation of the connecting seat and the inner cover body.

In the inner cover of the pressure cooking appliance, the inner cover body is partially recessed to form a platform, and the clamping seat and the connecting seat are connected to the platform.

In the inner cover of the pressure cooking appliance, the outer side surface of the inner cover body is provided with a convex positioning part, and the clamping seat is abutted to the positioning part.

In the inner lid of the pressure cooking appliance, the fastening member is a screw, and the screw penetrates through the clamping seat from outside to inside and is locked on the connecting seat.

In the inner cover of the pressure cooking appliance, a counter bore for accommodating the head of the screw and a sealing plug for plugging the counter bore are arranged on the clamping seat.

In the inner cover of the pressure cooking appliance, the bottom surface of the clamping seat is provided with a supporting bulge which is abutted against the inner cover body.

In the inner lid of the above pressure cooking appliance, a sealing member is provided between the clamping seat and the inner lid body and/or between the connecting seat and the inner lid body.

The utility model also provides a pressure cooking appliance, which comprises a pot body and a pot cover, wherein the pot cover comprises an upper cover and the inner cover in any technical scheme, and the inner cover is detachably connected with the upper cover.

The utility model has the beneficial effects that:

according to the inner cover, the clamping seat and the connecting seat are connected through the fastening piece and are fixed on the inner cover body in an internal-external clamping manner, and the clamping seat, the connecting seat and the inner cover are assembled at one time, so that unnecessary independent assembly procedures of parts are reduced, and the assembly efficiency of a production line is improved; the rotation stopping structure for limiting relative rotation is arranged between the clamping seat and the connecting seat, the fastener between the clamping seat and the connecting seat is more convenient to connect and operate, the assembling difficulty is reduced, the problem that the fastener is loosened due to relative rotation of the clamping seat and the connecting seat can be avoided in use, and the use reliability is improved.

Furthermore, the rotation stopping structure comprises a rotation stopping hole formed in the clamping seat and a rotation stopping boss arranged on the connecting seat, and the rotation stopping boss is in non-circular fit with the rotation stopping hole. The rotation stopping structure is simple and easy to process and assemble.

Furthermore, be equipped with the pilot hole on the inner cup body, the boss that splines runs through the pilot hole and with the pilot hole non-circular cooperation, in order to restrict the connecting seat with the relative rotation of inner cup body. Because the rotation stopping structure between the clamping seat and the connecting seat limits the relative rotation of the clamping seat and the connecting seat, when the connecting seat and the inner cover body are limited to rotate relatively, the clamping seat cannot rotate relative to the inner cover body, the clamping seat, the connecting seat and the inner cover are circumferentially relatively fixed, the assembly difficulty is further reduced, and the clamping seat and the connecting seat can be prevented from rotating relative to the inner cover in use to influence the installation of the inner cover.

Furthermore, the lateral surface of inner cup body is equipped with convex location portion, the joint seat supports and leans on location portion. When the clamping seat is installed, the positioning portion guides the clamping seat to be installed at the preset position of the preset inner cover body, the assembling efficiency is improved, and the clamping seat is abutted against the positioning portion to better prevent the clamping seat from rotating during use.

Furthermore, the fastener is a screw, and the screw penetrates through the clamping seat from outside to inside and is locked on the connecting seat. The fixing mode of screw connection is simple, easy to operate and low in cost; the screw outside-in runs through the clamping seat and locks to the connecting seat, so the connecting seat does not need to be punched in the installation, and the increase of the air leakage risk caused by the punching of the connecting seat is avoided.

Furthermore, a counter bore for accommodating the head of the screw and a sealing plug for plugging the counter bore are arranged on the clamping seat. The screw head is hidden in the clamping seat and is shielded by the sealing plug, so that the screw head is prevented from being exposed to influence attractiveness, a waterproof and dustproof effect is achieved, and the situation that the screw is rusted and food residues enter the counter bore to increase the cleaning difficulty due to the fact that liquid such as water enters the counter bore is avoided.

Furthermore, the bottom surface of the clamping seat is provided with a supporting bulge which is abutted against the inner cover body. When there is the position installation joint seat of curved surface or other unevennesses at inner cup body lateral surface, can't guarantee that the joint seat installation is steady, this scheme sets up the support arch at joint seat bottom surface, through the lateral surface of the protruding butt inner cup body of support, reduces joint seat and inner cup body area of contact, makes the joint seat steadily be fixed in on the inner cup body.

The pressure cooking appliance provided by the utility model comprises the inner cover in any technical scheme, so that the pressure cooking appliance has the technical effects brought by any technical scheme.

These features and advantages of the present invention will be disclosed in more detail in the following detailed description and the accompanying drawings.
