[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: By arranging the sealing ring, when the liquid discharge hole is communicated with the communication hole, the soup in the pot body can enter the sealing cavity at the lower end of the piston ring, so that the meat and vegetables in the pot body are separated from the soup, which is convenient for the user to pick up the meat and vegetables and is convenient for eating without the need to stir laboriously to find the food to be eaten; when the oil filtering hole is communicated with the communication hole, the soup in the sealing cavity often mixes with seasoning residues, meat and vegetable debris, etc. During the process that the soup passes through the oil filtering hole and enters the pot body, the residues and debris cannot enter the pot body, so that the soup in the pot body is clean, the flavor of the soup is maintained, and the edible taste is improved.

[0025] In the present invention, by providing a stirring ring, when the stirring ring rotates in the reverse direction, the lead screw rotates in the reverse direction, and the piston ring moves downward to the lower limit position under the action of the thread guide. The soup in the pot body cannot flow into the sealing cavity, so that there is sufficient soup in the pot body. At the same time, when the stirring ring rotates in the reverse direction, the stirring rod placed on the stirring ring enters the driving hook, and the stirring rod moves synchronously with the stirring ring, so that the meat and vegetables in the soup are stirred, making the meat and vegetables evenly heated and improving the edible taste. When the stirring ring rotates in the forward direction, the piston ring moves to the upper limit position under the action of the thread guide, and the soup in the pot body flows into the sealing cavity. The meat and vegetables in the pot protrude. At the same time, when the stirring ring rotates in the forward direction, the stirring rod on the upper cover of the stirring ring is separated from the driving hook, and the stirring rod no longer moves synchronously with the stirring ring. The stirring rod is relatively fixed to the housing, which is convenient for using the meat and vegetables in the pot body. No new moving mechanism and operating steps are added, and it is simple and convenient to use.

[0026] In the present invention, by providing a knob, when the knob rotates, it drives the eccentrically arranged eccentric column to rotate, thereby causing the switching rod to rotate. The rotation of the switching rod drives the sliding of the reversing shaft, so that the rotation direction of the stirring ring is changed. At the same time, the rotation of the switching rod drives the sliding of the switching pipe, so that the communication hole is communicated with the drain hole or the oil filtering hole, so that the soup containing residues flows out of the pot body, and the pure soup flows into the pot body. No new operating steps and moving mechanisms are added, and it is simple and convenient to use.

[0027] The present invention can absorb the oil fume dissipated from the upper part of the pot body, so as to keep the drinking environment clean and hygienic; the present invention can automatically stir the meat and vegetables in the pot body, making the meat and vegetables evenly heated and improving the edible taste of the meat and vegetables; the present invention can automatically filter the vegetables, separating the soup from the meat and vegetables, which is convenient for the eater to pick up without having to search laboriously; the present invention can filter the soup, keeping the soup pure and with a good taste, thereby enhancing the taste experience.

[0042] When only the drain holes 211 communicate with the communication holes 201, the piston ring 43 slides upward to reduce the pressure in the sealing cavity, and the soup in the pot body 20 sequentially enters the sealing cavity through the communication holes 201 and the drain holes 211, separating the meat and vegetables in the pot body 20 from the soup, thereby facilitating the user to select the meat and vegetables to be picked up.

[0043] When only the oil filtering holes 212 communicate with the communication holes 201, the piston ring 43 slides downward to compress the sealing cavity, and the soup in the sealing cavity sequentially enters the pot body 20 through the oil filtering holes 212 and the communication holes 201. The oil filtering holes 212 filter the soup entering the pot body 20, so that the soup in the pot body 20 remains pure, improving the taste of eating.

[0047] When the stirring ring 46 rotates forward, the piston ring 43 can slide upward under the guidance of the thread. The pressure in the sealing cavity decreases, and the soup in the pot body 20 can flow into the sealing cavity, separating the meat and vegetables in the pot body 20 from the soup. At the same time, the stirring rod 6 can rotate relative to the stirring ring 46 under the obstruction of the meat and vegetables, thereby driving the driving hook 47 to rotate.

[0064] The driving part 5 also includes a worm 55 which is rotatably connected to the rotating shaft in the housing 10 and is longitudinally arranged and transmission-connected to the worm wheel 54; a worm synchronous wheel 551 is fixedly connected to the central position of the lower end of the worm 55; a centrifugal synchronous wheel 511 is fixedly connected to the central position of the lower end of the centrifugal wheel 51; a motor synchronous wheel 581 is fixedly connected to the output shaft of the driving motor 58; a synchronous belt 59 which is transmission-connected to the centrifugal synchronous wheel 511, the worm synchronous wheel 551 and the motor synchronous wheel 581 is respectively arranged on the periphery of the centrifugal synchronous wheel 511, the worm synchronous wheel 551 and the motor synchronous wheel 581.

[0065] An annular groove 522 is formed on the outer periphery of the reversing shaft 52 coaxially; one end of the switching rod 53 close to the annular groove 522 is formed with a U-shaped fork 531 for driving the axial sliding of the annular groove 522; a convex head for driving the axial sliding of the annular groove 522 and slidably connected to the annular groove 522 is formed inside the U-shaped fork 531; the reversing shaft 52 can rotate circumferentially inside the U-shaped fork 531, and the rotation of the reversing shaft 52 drives the axial sliding of the reversing shaft 52.

[0066] An outwardly protruding positioning block 562 is formed on the outer wall of the knob 56; a rotating seat 104 rotatably connected to the knob 56 is formed inside the housing 10 in the installation area 107; a plurality of positioning grooves 1041 for hindering the movement of the positioning block 562 are formed on the inner wall of the housing 10; when the knob 56 is in the left extreme position, the positioning block 562 is located in one of the positioning grooves 1041; when the knob 56 is in the right extreme position, the positioning block 562 is located in another positioning groove 1041, and when the knob 56 is in the middle, the positioning block 562 is located in other positioning grooves 1041.

[0067] A display screen 11 for displaying the working state is arranged on the outer wall of the housing 10; control buttons 12 for function switching are arranged on the outer wall of the housing 10.

[0068] A controller and a power module are arranged inside the housing 10; the power module can be inserted into a household socket; the power module, the display screen 11, the control buttons 12, the heater 31, the gravity sensor 32, and the drive motor 58 are electrically connected to the controller.

[0069] In the initial state, the sealing ring 21 seals the communication hole 201, and the piston ring 43 is located at the lower extreme position; the positioning block 562 is engaged with the positioning groove 1041 in the middle.

[0070] When using the present invention, the user places the housing 10 on the tabletop. Then, the stirring gear 49 in the piston part 4 is aligned with the reversing shaft 52, and at the same time, each air outlet 4111 is aligned with each flow guide pipe 1022 in turn. The piston part 4 is installed on the housing 10 so that each air outlet 4111 is respectively communicated with the corresponding flow guide pipe 1022. At this time, the reversing bevel gear 491 does not contact the forward bevel gear 521a and the reverse bevel gear 521b. Next, the pot body 20 is placed into the piston part 4, and the driven column 213 is aligned with the opening groove 572. The pot body 20 is released, and the pot body 20 will slide downward to the limit position under the action of gravity. The driven column 213 enters the opening groove 572. At this time, the piston ring 43 is in sealed sliding connection with the outside of the pot body 20, and a relatively sealed cavity is formed in the space below the piston ring 43. Then the power is turned on, and meat, vegetables, soup, etc. are placed into the pot body 20. The switch is turned on, and the controller controls the heater 31 to heat the pot body 20. The soup in the pot body 20 is heated and then the meat and vegetables are cooked.

[0071] The present invention can extract the oil fume emitted from the upper part of the pot body 20. After the soup boils, a large amount of water vapor, oil fume, etc. will escape from the upper part of the pot body 20. When extracting the oil fume, the "oil fume extraction" function is turned on by operating the control button 12, and the controller controls the driving motor 58 to work, so that the motor synchronous pulley 581 rotates. The rotation of the motor synchronous pulley 581 drives the centrifugal synchronous pulley 511 to rotate through the synchronous belt 59, and then the centrifugal wheel 51 rotates. The gas in the centrifugal chamber 102 escapes outward through the discharge pipe 1021 under the centrifugal action of the centrifugal wheel 51, so that the pressure in the centrifugal chamber 102 decreases. The external pressure causes the external air to flow through the air inlet hole 4112, the air collecting chamber 411, the air outlet 4111, and the flow guide pipe 1022 in turn and enter the centrifugal chamber 102, and so on. The air flowing through the air inlet hole 4112 will cause the oil fume and water vapor escaping from the upper part of the pot body 20 to flow into the centrifugal chamber 102 together with the air flow, and then escape outward through the discharge pipe 1021, and finally be purified by the purification device communicated with the discharge pipe 1021. The water vapor, oil fume, etc. on the upper part of the pot body 20 cannot contact the user, thereby improving the hygiene level and comfort of the dining environment, and thus improving the user experience.

[0072] The present invention can stir the meat and vegetables in the pot body 20, can effectively prevent the meat and vegetables from adhering to the pot wall, and can also make the meat and vegetables evenly heated, thereby improving the taste of the meat and vegetables. When stirring the meat and vegetables, the knob 56 is turned to the left to the limit position, and the knob 56 rotates to drive the positioning block 562 to rotate. The rotation of the positioning block 562 will overcome the obstruction of the positioning groove 1041 located in the middle, so that the positioning block 562 is engaged with the positioning groove 1041 located on the left, and the knob 56 is relatively fixed to the housing 10. The rotation of the knob 56 drives the eccentric column 561 to rotate, and the rotation of the eccentric column 561 drives the switching groove 532 to rotate, thereby rotating the switching rod 53, and the rotation of the switching rod 53 drives the U-shaped fork 531 to move, and the movement of the U-shaped fork 531 drives the annular groove 522 to move, thereby causing the reversing shaft 52 to slide, thereby causing the reverse bevel gear 521b to be transmission-connected with the reversing bevel gear 491. The motor synchronous wheel 581 rotates, and synchronously drives the worm synchronous wheel 551 to rotate through the synchronous belt 59, thereby causing the worm 55 to rotate. The rotation of the worm 55 drives the worm wheel 54 to rotate, thereby causing the inner driving column 5411 to rotate. The rotation of the inner driving column 5411 drives the outer driven groove 523 to rotate, thereby causing the reversing shaft 52 to rotate, that is, causing the reverse bevel gear 521b to rotate. The rotation of the reverse bevel gear 521b drives the reversing bevel gear 491 to rotate, thereby causing the stirring gear 49 to rotate in the reverse direction. The reverse rotation of the stirring gear 49 drives the inner ring gear 461 to rotate, thereby causing the stirring ring 46 to rotate in the reverse direction. Next, place the stirring rod 6 on the upper end of the stirring ring 46. The rotation of the stirring ring 46 drives the driving hook 47 to rotate. The rotation of the driving hook 47 causes the stirring rod 6 to enter the driving hook 47, thereby causing the stirring rod 6 to be relatively fixed to the stirring ring 46. The stirring ring 46 drives the stirring rod 6 to rotate synchronously, and the paddle 61 on the stirring rod 6 paddles the meat and vegetables back and forth, so that the meat and vegetables in the pot body 20 are stirred without manual intervention and without adding a new motion mechanism, which is simple and convenient to use.

[0073] During the process of stirring the vegetables, the rotation of the inner ring gear 461 drives the screw gear 422 to rotate, thereby causing the screw 42 to rotate in the opposite direction. The screw 42 rotates in the opposite direction, causing the piston ring 43 to move downward under the guidance of the thread. The piston ring 43 moves downward, causing the inner thread 431 to move to the outer periphery of the optical axis 421. At the same time, the piston ring 43 abuts against the lower spring 44, thereby causing the lower spring 44 to compress and store force, and the piston ring 43 is relatively fixed to the housing 10. At the same time, the rotation of the switching rod 53 synchronously drives the toggle slot 533 to rotate, and the toggle slot 533 drives the switching column 571 to move, thereby causing the switching tube 57 to slide to the right, that is, the opening slot 572 slides, and the sliding of the opening slot 572 drives the driven column 213 to move, thereby causing the sealing ring 21 to rotate. The rotation of the sealing ring 21 causes the oil filter hole 212 to communicate with the connecting hole 201, and the soup in the pot body 20 flows outward through the connecting hole 201 and the oil filter hole 212 to the sealing cavity at the lower end of the piston ring 43. The sealed cavity at the lower end of the piston ring 43 has a relatively small volume, so only a small portion of the soup in the pot body 20 flows out, which does not affect the consumption of the hot pot.

[0074] When having hot pot, since the meat and vegetables are submerged in the soup, the user cannot pick up the food they want to eat. The present invention can separate the meat and vegetables from the soup, thus facilitating the consumption of food. When separating, the user turns the knob 56 to the extreme position to the right. The rotation of the knob 56 drives the positioning block 562 to rotate. The rotation of the positioning block 562 will overcome the obstruction of the positioning groove 1041 on the left side, and then the positioning block 562 is engaged with the positioning groove 1041 on the right side, and the knob 56 is relatively fixed with the housing 10. The rotation of the knob 56 drives the switching rod 53 to rotate. The rotation of the switching rod 53 drives the switching pipe 57 to slide to the left and then drives the sealing ring 21 to rotate, so that the liquid discharge hole 211 is communicated with the communication hole 201, and the inside of the pot body 20 is communicated with the sealing cavity. At the same time, the rotation of the switching rod 53 drives the U-shaped fork 531 to move. The movement of the U-shaped fork 531 drives the reversing shaft 52 to slide, and then the positive bevel gear 521a is in transmission connection with the reversing bevel gear 491. The driving motor 58 drives the worm 55 to rotate. The rotation of the worm 55 drives the worm gear 54 to rotate and then the positive bevel gear 521a to rotate. The rotation of the positive bevel gear 521a drives the reversing bevel gear 491 to rotate and then the stirring gear 49 to rotate forward. The forward rotation of the stirring gear 49 drives the inner ring gear 461 to rotate and then the stirring ring 46 to rotate forward. The forward rotation of the stirring ring 46 drives the lead screw 42 to rotate forward. Under the elastic force of the lower spring 44, the piston ring 43 makes the internal thread 431 in transmission connection with the lead screw 42. The piston ring 43 slides upward under the action of the thread guide. The volume of the sealed space at the lower end of the piston ring 43 increases, and the pressure decreases. The external pressure causes the soup in the pot body 20 to enter the sealing cavity through the liquid discharge hole 211 under the pressure. The soup in the pot body 20 flows out, so that the meat and vegetables are separated from the soup, and then it is convenient for the user to pick up the food they want to eat.

[0075] During the forward rotation of the stirring ring 46, under the obstruction of the meat and vegetables, as the stirring ring 46 rotates forward, the stirring rod 6 will be separated from the driving hook 47. As the stirring ring 46 continues to rotate forward, the stirring rod 6 will abut against the driven arc surface 471, and the stirring ring 46 will rotate away from the driven arc surface 471, and the return torsion spring 48 will twist and store energy. When the driving hook 47 is not in contact with the stirring rod 6, the driving hook 47 returns to its original position under the elastic force of the return torsion spring 48. In this way, the rotation of the stirring ring 46 cannot drive the stirring rod 6 to move, and the meat and vegetables in the pot body 20 are convenient for the user to pick up. As the stirring ring 46 continues to rotate forward, the piston ring 43 will gradually move to the upper extreme position, the internal thread 431 will move to the outer periphery of the upper optical axis 421, and the upper spring 45 will be compressed and store energy. The piston ring 43 is relatively fixed with the housing 10.

[0076] When it is necessary to cook meat and vegetables again after clamping, the user turns the knob 56 to the left to the left extreme position, so that the reverse bevel gear 521b is in transmission connection with the stirring gear 49, and the driving motor 58 drives the stirring ring 46 to rotate in the reverse direction. The piston ring 43 moves to be in transmission connection with the lead screw 42 under the elastic force of the upper spring 45. At the same time, turning the knob 56 to the left drives the switching rod 53 to turn to the right, and further causes the switching pipe 57 to slide to the right. The sliding of the switching pipe 57 to the right drives the sealing ring 21 to rotate, and further causes the oil filtering hole 212 to communicate with the communication hole 201, that is, the inside of the pot body 20 communicates with the sealing cavity. The reverse rotation of the stirring ring 46 drives the reverse rotation of the lead screw 42, and further causes the piston ring 43 to move downward to the lower extreme position under the action of the thread guidance. The sealing cavity is compressed, and the soup in the sealing cavity enters the inside of the pot body 20 again through the oil filtering hole 212 and the communication hole 201 in sequence. The soup entering the sealing cavity often contains a lot of seasoning residues, meat and vegetable debris, etc. When the soup enters the pot body 20 through the oil filtering hole 212, the residues and debris cannot pass through the oil filtering hole 212, so that the soup entering the pot body 20 again is cleaner, maintaining the taste of the soup, that is, improving the user's taste experience.

[0077] After use, turn the knob 56 to the initial position, turn off the "oil extraction" function, turn off the switch and disconnect the power supply. Clean the soup, meat and vegetables in the pot body 20, take out the piston part 4 and the pot body 20 in sequence, clean the whole, and store it after cleaning.

[0078] By setting the sealing ring 21, when the liquid discharge hole 211 communicates with the communication hole 201, the soup in the pot body 20 can enter the sealing cavity at the lower end of the piston ring 43, so that the meat and vegetables in the pot body 20 are separated from the soup, which is convenient for the user to clamp the meat and vegetables and convenient for eating, without the need to stir hard to find the food to be eaten; when the oil filtering hole 212 communicates with the communication hole 201, the soup in the sealing cavity often contains seasoning residues, meat and vegetable debris, etc. When the soup passes through the oil filtering hole 212 and enters the pot body 20, the residues and debris cannot enter the pot body 20, so that the soup in the pot body 20 is clean, maintaining the flavor of the soup and improving the taste experience.

[0079] In the present invention, by providing a stirring ring 46, when the stirring ring 46 rotates in the reverse direction, the lead screw 42 rotates in the reverse direction, and the piston ring 43 moves downward to the lower limit position under the action of the thread guide. The soup in the pot body 20 cannot flow into the sealed cavity, ensuring that there is sufficient soup in the pot body 20. At the same time, the reverse rotation of the stirring ring 46 causes the stirring rod 6 placed on the stirring ring 46 to enter the driving hook 47, and the stirring rod 6 moves synchronously with the stirring ring 46, so that the meat and vegetables in the soup are stirred, making the meat and vegetables evenly heated and improving the eating taste. When the stirring ring 46 rotates in the forward direction, the piston ring 43 moves to the upper limit position under the action of the thread guide, and the soup in the pot body 20 flows into the sealed cavity, with the meat and vegetables in the pot body 20 protruding. At the same time, the forward rotation of the stirring ring 46 causes the stirring rod 6 covered on the stirring ring 46 to separate from the driving hook 47, and the stirring rod 6 no longer moves synchronously with the stirring ring 46. The stirring rod 6 is relatively fixed to the housing 10, facilitating the use of the meat and vegetables in the pot body 20. Without adding new motion mechanisms and operation steps, it is simple and convenient to use.

[0080] In the present invention, by providing a knob 56, when the knob 56 rotates, it drives the eccentrically arranged eccentric post 561 to rotate, thereby causing the switching rod 53 to rotate. The rotation of the switching rod 53 drives the sliding of the reversing shaft 52, thus changing the rotation direction of the stirring ring 46. At the same time, the rotation of the switching rod 53 drives the sliding of the switching tube 57, so that the communication hole 201 is communicated with the drain hole 211 or the oil filtering hole 212, enabling the soup containing residues to flow out of the pot body 20 and the pure soup to flow into the pot body 20. Without adding new operation steps and motion mechanisms, it is simple and convenient to use.

[0081] The present invention can extract the oil fume dissipated from the upper part of the pot body, thus keeping the drinking environment clean and hygienic; the present invention can automatically stir the meat and vegetables in the pot body, making the meat and vegetables evenly heated and improving the eating taste of the meat and vegetables; the present invention can automatically filter the vegetables, separating the soup from the meat and vegetables, facilitating the eater to pick up without having to search laboriously; the present invention can filter the soup, keeping the soup pure and with a good taste, thereby enhancing the taste experience.
