Wherein the pot cover 1 can be screwed on the pot body 2, when the screwing is started, the polygonal piston block 31 is firstly matched with the polygonal inner hole 22, so that the rotation of the polygonal piston block 31 is limited, the pot cover 1 is screwed and rotated to drive the tightly-stirring volute spring 42 to have elastic potential energy, so that the threaded sleeve 41 on the inner ring of the polygonal piston block is driven to rotate, because the rotation direction of the threaded rod 32 is limited at the moment, the threaded sleeve 41 rotates at the moment, the polygonal piston block 31 is driven to slide downwards, so that the space below the polygonal piston block 31 is compressed, the internal air pressure is increased, because the elastic potential energy released by the volute spring 42 at the moment is a trend force, the force at the moment is an elastic force, when the internal air pressure and the elastic potential energy of the volute spring 42 are balanced, the internal air pressure and the volute spring are static, when the internal air pressure is reduced along with the reduction of the temperature, the volute spring 42 continues to release the elastic potential energy, so that the internal air pressure and the volute spring are in a balanced state again, so that the air pressure inside the pot body 2 can be automatically maintained in a relatively stable state.
The pressurizing device 5 comprises an air cylinder 51, a first gear 52, a rack 53 and a guide rail 54, the air cylinder 51 comprises a piston sleeve 511, a piston rod 512, an air outlet 513 and an air inlet 514, the guide rail 54 and the piston sleeve 511 are arranged on the upper end surface of the polygonal piston block 31 and are arranged in parallel, one end of the piston rod 512 is arranged in the piston sleeve 511 in a sliding manner, the other end of the piston rod 512 is connected onto the rack 53, the rack 53 is arranged on the guide rail 54 in a sliding manner, an outward air outlet check valve is arranged on the air outlet 513 and is derived from the upper end surface of the polygonal piston block 31 to the position below the lower end surface thereof, an inward air inlet check valve is arranged on the air inlet 514, a laminated plate 11 is arranged in the middle of the pot cover 1, a hollow shaft 12 is arranged in the middle of the laminated plate 11, the outer wall of the lower end of the hollow shaft 12 is provided with the first gear 52, and is arranged in a meshing manner with the rack 53, the pot cover 1 is provided with the air holes 13, and external air can enter the space below the layered plate 11, so that when the cover is opened, the external air can enter the air inlet 514 through the air holes 13, and then enter the piston sleeve 511, and therefore the air entering the inside is fresh air each time.
When the cooker lid 1 is screwed, the first gear 52 is driven to rotate, and because the rotation of the polygonal piston block 31 is limited at the moment, the first gear 52 rotates to drive the rack 53 to slide on the guide rail 54, so that the piston rod 512 is driven to slide forwards, air is injected into the cavity below the polygonal piston block 31, the air pressure in the cooker is increased, the cooker lid 1 can be inflated and pressurized every time when being stewed, the internal air pressure is increased, and food is easier to stew when the cooker lid is used.
Since the cookware is braised with the energy of hot water, after the braising time is long, the internal temperature is reduced certainly, so that the internal air pressure is reduced, when the cookware is opened, the cookware cover 1 is reversely screwed, so that the volute spiral spring 42 is loosened, the elastic potential energy of the volute spiral spring 42 is reduced, so that the air pressure below the polygonal piston block 31 is greater than the external air pressure, the polygonal piston block 31 slides upwards, but the internal air volume is contracted due to the reduction of the temperature, when the internal and external air pressures are kept balanced, the position of the polygonal piston block 31 is lower than the position of the cookware cover 1, so that the air is injected inwards at the beginning, the total amount of the internal air is increased, and the cookware is more convenient to open the cookware cover after the cookware is used.
The working principle or the using method is as follows:
when the cooker cover is used, food and hot water are placed into the cooker body 2, the cooker cover 1 is covered on the cooker body 2, the polygonal piston block 31 is aligned with the polygonal inner hole 22, the cooker cover 1 starts to be screwed, the downward screwing of the cooker cover 1 can generate certain downward displacement, the polygonal piston block 31 is driven to be pressed into the polygonal inner hole 22 when the cooker cover is screwed down, the cooker cover 1 is screwed and rotated to drive the stirring volute spring 42 to have elastic potential energy, so that the threaded sleeve 41 on the inner ring of the volute is driven to rotate, and the threaded sleeve 41 rotates at the moment because the rotation direction of the threaded rod 32 is limited, so that the polygonal piston block 31 is driven to slide downwards, the space below the volute is compressed, and the internal air pressure is increased.
When the cooker lid 1 is screwed, the first gear 52 is driven to rotate, and because the rotation of the polygonal piston block 31 is limited at the moment, the first gear 52 rotates to drive the rack 53 to slide on the guide rail 54, so that the piston rod 512 is driven to slide forwards, air is injected into the cavity below the polygonal piston block 31, the air pressure in the cooker is increased, the cooker lid 1 can be inflated and pressurized every time when being stewed, the internal air pressure is increased, and food is easier to stew when being used.
When the cooker cover 1 is just covered, the spiral spring 42 is tightly stirred and releases elastic force, when the internal air pressure and the elastic potential energy of the spiral spring 42 are kept balanced, the two are static, and when the internal air pressure is reduced along with the reduction of the temperature, the spiral spring 42 continuously releases the elastic potential energy to enable the two to be in a balanced state again, so that the air pressure in the cooker body 2 can be automatically maintained in a relatively stable state, the automatic pressure maintaining function is realized, and food can be more easily braised and cooked during long-time stewing.
After the use, the pot cover 1 is reversely opened, so that the elastic potential energy of the spiral spring 42 is released, after the pot cover is taken away from the pot body 2, the rotation limitation of the polygonal piston block 31 disappears, and the threaded rod 32 rotates upwards and rises back under the action of the first elastic piece 33 to return to the initial state, so that the pot cover is convenient to use next time.
