The pot body 20 is substantially in a rounded rectangular parallelepiped shape and has a cylindrical inner pot accommodating portion into or from which the inner pot 21 can be freely put or taken out to facilitate cleaning of the inner pot 21. The inner pot 21 is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. The pot body 20 may include therein heating means for heating the inner pot 21.

The lid body 10 has a substantially rounded rectangular parallelepiped shape and substantially corresponds to the shape of the pot body 20. The lid body 10 is pivotally connected to the pot body 20 in an openable and closable manner for covering the pot body 20. When the lid 10 is closed on the pot body 20, it covers the inner pot 21 and forms a cooking space with the inner pot 21. Also, the lid body 10 is usually provided with a sealing ring, which may be made of, for example, a rubber material, and is disposed between the lid body 10 and the inner pot 21 for sealing the cooking space when the lid body 10 is in a closed state. In the working process of the pressure cooking appliance, the cooking space of the pressure cooking appliance is filled with steam, so that the pressure in the cooking space is greater than the normal pressure, and food can be cooked better. The cooking space is also communicated with the outside through a steam passage (not shown in the figure), so that when the pressure in the cooking space is overlarge, partial steam can be discharged through the steam passage to adjust the pressure in the cooking space and prevent danger caused by the overlarge pressure. That is, the pressure in the cooking space can be adjusted by controlling the opening and closing of the steam passage. The steam passage may be provided on the pot body 20 or the lid body 10.

In the present embodiment, the steam channel is provided on the cover 10. In addition, the cover 10 is provided with a blocking device (for example, a heavy gravity ball, not shown in the figure) which can move between an open position and a closed position to adjust the opening and closing of the steam passage. In particular, the blocking means shut off the steam passage in the closed position, while the cooking space remains sealed; when the blocking means is in the open position, the cooking space may be in communication with the outside through the steam passage. In this embodiment, the blocking means is preferably spherical to facilitate movement between the closed position and the open position.

As shown in fig. 2, a pressure adjustment device 11 is provided on the cover 10 to control the movement of the blocking device. As shown in fig. 3 and 4, the pressure adjusting device 11 includes a fixed portion 12 and a movable portion 13. The fixed portion 12 is fixedly provided on the lid 10, and the movable portion 13 is a substantially rod-shaped movable shaft that is provided through the fixed portion 12 and is capable of reciprocating relative to the fixed portion 12 along the axis of the movable shaft itself. The pressure regulating means 11 controls the movement of the blocking means between the closed position and the open position by means of the movement of the movable part 13. The fixed part 12 functions to support the movable part 13 and to define a moving locus of the movable part 13. Therefore, it is understood that, in other embodiments, the fixed portion 12 may not be provided, but the movable portion 13 may be directly movably provided on the cover 10, as long as the movement of the stopper device by the movement of the movable portion 13 can be controlled. Preferably, the blocking means can be made of a magnetic material in the form of a sphere, and the movable part 13 can be provided in the form of an electromagnet, so that the blocking means can be better controlled by magnetic force.

As shown in fig. 4, the movable portion 13 configured as a movable shaft has a stopper portion 14 provided in a cylindrical shape coaxial with the movable shaft to prevent the movable portion 13 from coming off the fixed portion 12. The limiting part 14 is arranged to be cylindrical and coaxial with the movable shaft, so that interference between the limiting part 14 and parts arranged along the moving path of the movable part 13 can be avoided to the greatest extent in the moving process of the movable part 13, the structure is simple, and production and manufacturing are facilitated. When the pressure in the cooking space is adjusted, the movable portion 13 moves relative to the fixed portion 12 to control the movement of the stopper, and the stopper portion 14 inevitably collides with the fixed portion 12. And many parts are often arranged on the cover body 10 of the pressure cooking appliance, the layout is very compact, and the movement of the movable part 13 can collide with other parts. Which are undesirable. And collision between spare part can produce very big noise, causes noise pollution, influences user's use experience, and frequent collision still can lead to the damage of spare part easily, shortens its life. Therefore, the muffler device is provided at a position where the movable portion 13 easily collides with another component. The silencing device can be a part or material with a buffering effect, such as a spring, silicon rubber or plastic. When the movable part 13 collides with other parts, the muffler buffers the collision, so that the noise is reduced, and the damage degree of the parts caused by the collision can be reduced.

In the present embodiment, specifically, the muffler device 15 is provided on the stopper portion 14 of the movable portion 13. The concrete structure of the silencing device 15 is as shown in fig. 5, the silencing device 15 is cylindrical with a cavity, the side of the cylinder is provided with an opening communicated with the cavity, at least one end face of the cylinder is provided with a through hole, and the structure is favorable for conveniently coating the silencing device 15 on the limiting part 14. In a state where the muffler device 15 is connected to the stopper portion 14, a surface 151 of the muffler device 15 facing the fixing portion 12 and a surface 152 thereof away from the fixing portion 12 are provided as sound deadening surfaces, respectively. This is because in the present embodiment, the movable portion 13 is configured to move in the axial direction thereof, and therefore, only the surface 151 and the surface 152 of the muffler device 15 may collide with the fixed portion 12 or other parts along with the movement of the movable portion 13. The shape of the muffler device 15 is preferably similar to that of the stopper portion 14, however, the muffler device 15 may have other different shapes. It is understood that when the structure and the moving manner of the movable portion 13 are changed, the structure of the sound deadening surface of the sound deadening device 15 is also changed, and in short, a portion of the sound deadening device 15 which can collide with other parts with the movement of the movable portion 13 is set as the sound deadening surface. The muffler 15 may be made of a material capable of cushioning, such as silicone rubber, as a whole or only a portion provided as a sound-deadening surface. In addition, in the present embodiment, no silencing device is provided on the working surface where the movable portion 13 pushes the blocking device, so as not to affect the control accuracy of the blocking device by the movable portion 13.

It is to be understood that in other embodiments, the silencing device may be provided on a component that collides with the movable portion, for example, on the fixed portion or another component of the cover, or the silencing device may be provided on both components that collide with each other (for example, the movable portion and the fixed portion).
