[0029] Please refer to the attached Figure 1 - attached Figure 9 , the embodiment of the present invention provides a rice cooker with micro pressure, including a cooking pot body 1. An air pressure generating mechanism 4 is fixedly connected to the outside of the cooking pot body 1. A jet mechanism 5 is arranged in the middle of the cooking pot body 1. A liquid collection mechanism 6 is arranged at the bottom end of the outside of the cooking pot body 1. The air pressure generating mechanism 4 is used to output gas for the jet mechanism 5 and the liquid collection mechanism 6. The gas is ejected through the jet mechanism 5. At the same time, the liquid collection mechanism 6 is used to collect water vapor. A sealing cover 2 is rotatably connected to the top of the cooking pot body 1. A handle 3 is fixedly connected to the top of the sealing cover 2. The handle 3 is used to open the sealing cover 2.

[0030] The air pressure generating mechanism 4 includes an air cylinder 401. The bottom of the air cylinder 401 is fixedly connected to the outside of the pot body 1. A tension spring 402 is arranged and connected inside the air cylinder 401. The tension spring 402 can use its own pulling force to pull the movable plug 403 downward, and then can prevent the sealing cover 2 from rotating to the top of the pot body 1 without external force. The movable plug 403 is slidably connected inside the air cylinder 401. The movable plug 403 can play a role in limiting and can also adjust the internal air pressure of the air cylinder 401. The top of the movable plug 403 is fixedly connected with an extension rod 404. One end of the outside of the air cylinder 401 is fixedly connected with a check valve 405. The other end of the outside of the check valve 405 is fixedly connected with a check valve 406. One end of the tension spring 402 is fixedly connected inside the air cylinder 401, and the other end of the tension spring 402 is fixedly connected to the bottom of the movable plug 403. When opening the lid, hold the handle 3 and rotate it upward, which can drive the sealing cover 2 to rotate upward, and then can drive the extension rod 404 to enter the inside of the air cylinder 401, so as to drive the movable plug 403 to move toward the bottom of the air cylinder 401. At this time, the check valve 406 is closed and the check valve 405 is opened. At this time, the air in the air cylinder 401 will enter the inside of the jetting mechanism 5. When closing the sealing cover 2, the handle 3 can be used to drive the extension rod 404 to move upward, and then can drive the movable plug 403 to move upward. At this time, the check valve 405 is closed and the check valve 406 is opened, so as to pump the air out of the liquid collection mechanism 6.

[0031] The jet mechanism 5 includes an air storage box 501 which provides an air storage space. The inner side of the air storage box 501 is fixedly connected to the outside of the pot body 1. An air pipe 502 is fixedly connected to the outside of the air storage box 501, and the air pipe 502 serves to connect and install. The top of the air pipe 502 is fixedly connected to an installation housing 503. A movable housing 504 is slidably connected inside the installation housing 503. A driving spring 505 is fixedly connected to the side of the movable housing 504 away from the pot body 1. One end of the driving spring 505 away from the movable housing 504 is fixedly connected inside the installation housing 503. A push rod 506 is fixedly connected to the side of the movable housing 504 away from the pot body 1. An air leakage hole 508 is opened at the bottom of the installation housing 503, and the movable housing 504 can block the air leakage hole 508. An exhaust hole 509 is opened at the bottom of the movable housing 504. When the exhaust hole 509 is aligned with the air leakage hole 508, exhaust can be achieved. A ventilation pipe 511 is fixedly connected to the outside of the air storage box 501. One end of the ventilation pipe 511 away from the air storage box 501 is fixedly connected to the side of the one-way valve 405 away from the air cylinder 401. An air outlet pipe 507 is fixedly connected to the side of the movable housing 504 away from the push rod 506. One end of the push rod 506 away from the air outlet pipe 507 is fixedly connected to a round handle 510. The driving spring 505 is sleeved outside the push rod 506, and one end of the driving spring 505 away from the movable housing 504 is fixedly connected inside the installation housing 503. The air outlet pipe 507 is slidably connected to the end of the installation housing 503 away from the push rod 506. The push rod 506 penetrates through the end of the installation housing 503 away from the air outlet pipe 507. When the air inside the air cylinder 401 enters the inside of the air storage box 501, if there is cooked rice inside the pot body 1 when the sealing cover 2 is opened, at this time, the push rod 506 can be moved towards the pot body 1, thereby being able to push the movable housing 504 and the air outlet pipe 507 towards the pot body 1, and then being able to stretch the driving spring 505. When the exhaust hole 509 is aligned with the air leakage hole 508, the gas in the air storage box 501 enters the inside of the movable housing 504 through the air pipe 502, the air leakage hole 508 and the exhaust hole 509, and the air inside the air storage box 501 is ejected through the air outlet pipe 507, so as to be able to blow away the hot air on the rice and prevent the hot air from scalding the user.

[0032] The liquid collection mechanism 6 includes a water storage ring 601 which functions to store water. The inner side of the water storage ring 601 is fixedly connected to the outer bottom end of the pot body 1. An adjusting rod 602 is fixedly connected to the outer side of the water storage ring 601, and the adjusting rod 602 serves as a connection function. A drainage tube 603 is fixedly connected to the side of the adjusting rod 602 away from the water storage ring 601. A blocking sleeve 604 is slidably connected inside the drainage tube 603, and the blocking sleeve 604 functions to prevent gas from flowing out. An installation frame 605 is fixedly connected inside the blocking sleeve 604, and the installation frame 605 provides an installation position. A connection column 606 is fixedly connected to the top of the installation frame 605. A pushing spring 607 is sleeved outside the connection column 606. A circular plate 608 is fixedly connected to the top of the connection column 606. A water pipe 609 is fixedly connected to the outer side of the water storage ring 601, and the top of the water pipe 609 is fixedly connected to the top of the pot body 1. A water collecting groove 610 is formed at the top of the pot body 1. A pressure tube 611 is fixedly connected between the water storage ring 601 and the air storage box 501, and an electric valve 612 is fixedly connected to the middle of the pressure tube 611. A waterproof ventilation valve 613 is fixedly connected to the outer side of the water storage ring 601. An air suction tube 614 is fixedly connected between the waterproof ventilation valve 613 and the check valve II 406. One end of the pushing spring 607 is fixedly connected to the bottom of the circular plate 608, and the other end of the pushing spring 607 is fixedly connected to the top of the drainage tube 603. The top of the water pipe 609 is communicated with the water collecting groove 610. The connection column 606 penetrates through the top of the drainage tube 603. When the air pressure generating mechanism 4 pumps out the air in the water storage ring 601, the air pressure inside the water storage ring 601 becomes smaller, thus generating suction. When the sealing cover 2 is opened, water vapor will fall into the water collecting groove 610 and accumulate inside the water collecting groove 610. At this time, since the water storage ring 601 has suction, the water flow in the water collecting groove 610 will be sucked into the inside of the water storage ring 601, preventing the water flow inside the water collecting groove 610 from accumulating. When it is necessary to drain the water flow inside the water storage ring 601, the electric valve 612 is opened and gas is introduced into the inside of the water storage ring 601 through the pressure tube 611 to increase the air pressure, pressing the circular plate 608 downward, thereby driving the connection column 606 and the installation frame 605 to move downward, and then driving the blocking sleeve 604 to move downward. At this time, it is convenient for the water to enter the drainage tube 603 from the adjusting rod 602 under the action of air pressure, and since there is no blockage by the blocking sleeve 604, the water flow will flow out from the drainage tube 603.

[0033] Working principle: When opening the cover, hold the handle 3 and rotate it upward, which can drive the sealing cover 2 to rotate upward, and then drive the extension rod 404 into the interior of the air cylinder 401, thereby driving the movable plug 403 to move towards the bottom of the air cylinder 401. At this time, the check valve II 406 closes, and the check valve I 405 opens. At this time, the air in the air cylinder 401 will enter the interior of the jet mechanism 5. When closing the sealing cover 2, the extension rod 404 can be driven to move upward by the handle 3, and then the movable plug 403 can be driven to move upward. At this time, the check valve I 405 closes, and the check valve II 406 opens, so that the air can be pumped out from the liquid collection mechanism 6;

[0034] When the air in the air cylinder 401 enters the interior of the air storage box 501, if there is cooked rice in the pot body 1 when the sealing cover 2 is opened, the push rod 506 can be moved towards the pot body 1 at this time, so as to drive the movable shell 504 and the air outlet pipe 507 to move towards the pot body 1, and then the spring 505 can be driven to stretch. When the exhaust hole 509 is aligned with the air release hole 508, the gas in the air storage box 501 enters the interior of the movable shell 504 through the gas pipe 502, the air release hole 508 and the exhaust hole 509, and the air inside the air storage box 501 is ejected through the air outlet pipe 507, so as to blow away the heat on the rice and prevent the user from being scalded by the heat;

[0035] When the air pressure generating mechanism 4 pumps out the air in the water storage ring 601, the air pressure inside the water storage ring 601 becomes smaller, so that suction can be generated. When the sealing cover 2 is opened, the water vapor will fall into the interior of the water collecting tank 610 and gather inside the water collecting tank 610. At this time, the water storage ring 601 has suction, so the water flow in the water collecting tank 610 will be sucked into the interior of the water storage ring 601, which can prevent the water flow from gathering inside the water collecting tank 610. When the water flow inside the water storage ring 601 needs to be discharged, the electric valve 612 is opened and gas is introduced into the interior of the water storage ring 601 through the air pressure pipe 611 to increase the air pressure, and the disc 608 is pressed downward, so as to drive the connecting column 606 and the mounting bracket 605 to move downward, and then drive the blocking sleeve 604 to move downward. At this time, it is convenient for the water to enter the drain cylinder 603 from the connecting rod 602 under the action of air pressure, and since there is no blocking of the blocking sleeve 604, the water flow will flow out from the drain cylinder 603.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
