[0035] The cleaning bin 31 is provided with a collection groove 313 below the air hole disc 11, and at least one column of radial air collecting holes 111 of the air hole disc 11 is located in the area of the cleaning bin 31 and aligned with the collection groove 313 when the air hole disc 11 rotates.

[0036] The pot cover 1 is also provided with a driving device 12 for driving the air hole disc 11 to rotate, the driving device 12 comprises a driving wheel 121, a spiral spring 122 and a steam channel 123, the steam channel 123 is fixedly arranged on the cleaning bin 31, and the two ends thereof are rotatably connected with the upper passage air hole 114 and the lower passage air hole 115 of the air hole disc 11, respectively, so that the high-pressure steam collected by the air hole disc 11 flows into the steam channel 123 from the lower passage air hole 115, and then flows out from the upper end opening of the upper passage air hole 114, and the pressure valve 2 is arranged on the upper passage air cylinder 114 to adjust the pressure in the pressure cooker by its own weight.

[0037] The lower passage air hole 115 is separated from the upper passage air hole 114 on the air hole disc 11, the lower passage air hole 115 is connected with the steam channel 123 through a rotary joint, the steam channel 123 is connected with the upper passage air hole 114 through a through hole opened in the circumferential direction of the upper passage air hole 114, the air hole disc 11 is rotatably arranged on the steam channel 123, and the through hole in the circumferential direction of the upper passage air hole 114 is connected with the steam channel 123, so as to realize steam communication.

[0038] The driving wheel 121 is arranged on the pot cover 1 in one-way rotation, and the fan blades 1211 are uniformly arranged on the outer wall of the driving wheel 121 in the circumferential direction, and the rotation area of the fan blades 1211 is located in the steam channel 123, so that the high-pressure steam flowing in the steam channel 123 drives the fan blades 1211 to move, thereby driving the driving wheel 121 to rotate, and one end of the spiral spring 122 is connected to the inner wall of the driving wheel 121, and the other end of the spiral spring 122 is connected to the air hole disc 11.

[0039] Wherein the driving wheel 121 rotates the spiral spring 122, and the spiral spring 122 drives the air hole disc 11 to rotate, and the air hole disc 11 is arranged on the pot cover 1 in a damping rotation mode, so that when the pressure cooker discharges steam outward, the rotation speed of the driving wheel 121 is greater than that of the air hole disc 11, so that the spiral spring 122 is started to be tightened, and when the spiral spring 122 is completely tightened, the driving wheel 121 is no longer driven to rotate, and the high-pressure steam flows through the gap between the fan blade 1211 and the steam passage 123 and is discharged outward, so that during the time when the spiral spring 122 is tightened, the rotation speeds of the driving wheel 121 and the air hole disc 11 are consistent, and the spiral spring 122 is energized, and when all the air collecting holes 111 on the air hole disc 11 are blocked, that is, when there is no high-pressure steam flowing from the steam passage, the energy stored in the spiral spring 122 can also drive the air hole disc 11 to continue to rotate.

[0040] The cleaning bin 31 is further provided with a long strip-shaped first magnetic attraction member 311 covering the entire radius range of the air hole disc 11, and the first magnetic attraction member 311 is located above the cleaning notch 312, that is, above the air hole disc 11, and the second magnetic attraction member 1121 is arranged at the upper end of the push-out member 112, and the second magnetic attraction member 1121 has the same magnetic pole as the first magnetic attraction member 311, so that when the air hole disc 11 rotates and the second magnetic attraction member 1121 on the push-out member 112 passes below the first magnetic attraction member 311, the push-out member 112 slides downward under the action of magnetic repulsion, and the particles in the air collecting hole 111 are pushed downward, and at the same time the air hole disc 11 continues to rotate, so that the pushed particles are scraped into the collection groove 313 by the scraping member 32 arranged in the collection groove 313, and the air hole disc 11 continues to rotate, and the cleaning bin 31 continues to clean the air collecting hole 111 on the air hole disc 11.

[0042] The lower sliding stroke of the third magnetic attraction element 113 is less than that of the push-out element 112, and the third magnetic attraction element 113 enters below the first magnetic attraction element 311 before the second magnetic attraction element 1121, so that the third magnetic attraction element 113 pushes the pin element 1114 inserted on the screen element 1113 first, and then the push-out element 112 slides downward, thereby synchronously pushing the particles outside the screen element 1113 to the lower end surface of the gas collecting hole 111, which are aligned and cleaned by the scraping element 32.

[0043] The working principle or method of use is as follows: After the food to be cooked is put into the pressure cooker, the cover is closed and the pressure valve 2 is loaded on the upper passage air cylinder 114 of the cover 1.

[0044] After the pressure cooker starts heating, the internal gas pressure increases, and the gas is gathered to the lower passage air hole 115 of the air hole disc 11 through the gas collecting hole 111, and is discharged outward from the upper passage air cylinder 114 through the steam passage 123. When the steam gas pressure in the pressure cooker is greater than the gravity of the pressure valve 2, the upper passage air cylinder 11 starts to discharge gas outward.

[0045] At the beginning of the gas discharge, the steam drives the driving wheel 121 to rotate, thereby driving the air hole disc 11 to rotate and tightly stirring the volute spring to store energy.

[0046] The air hole disc 11 rotates, the cleaning bin 31 scrapes the bottom of the air hole disc 11, at the same time, the push-out element 112 slides downward to push the particles in the gas collecting hole 111 outward, and the particles are aligned and cleaned by the scraping element 32, thereby realizing cleaning while cooking, ensuring that the channel for discharging steam outward in the pressure cooker is unobstructed, thereby improving the safety of the pressure cooker.

[0047] At the same time, when the gas collecting hole 111 is completely blocked, i.e. there is no steam flowing through the steam passage, the volute spring can still drive the air hole disc 11 to rotate to clean the gas collecting hole 111, further ensuring the safety of the pressure cooker.

[0048] Example 2:

[0049] Referring to Figures 1-7 , compared with example 1, the difference is that the third magnetic attraction element 113 of the air hole disc 11, the rest are the same. The air hole disc 11 is provided with a third magnetic attraction element 113 between every two gas collecting holes 111 in the radial direction, and the third magnetic attraction element 113 is provided with two connecting rods connected with the pin elements 1114 on the left and right first passages 1111, thereby one third magnetic attraction element 113 controls the transverse movement of two pin elements 1114, thereby reducing the arrangement of the third magnetic attraction element 113 and reducing the production cost.
