Technical Field
[0001] This utility model relates to the field of hot pot technology, and in particular to a novel automatic lifting hot pot. Background Technology
[0002] Hot pot is a popular cooking method. When eating hot pot, ingredients are typically cooked in boiling broth and then removed by hand using chopsticks or a slotted spoon. However, manually removing food is often inconvenient. To address this issue, a new type of lifting hot pot has been developed. This lifting hot pot consists of a base, a pot body, and a hot pot frame. The base has an inner cavity, the pot body is located at the upper opening of the inner cavity, and the hot pot frame is located inside the pot body. The pot body holds the broth, and the hot pot frame holds the ingredients. By raising the hot pot frame, the cooked food is exposed in the broth, eliminating the need for manual removal. Currently, raising the hot pot frame usually requires manual operation, which is still inconvenient. There are also lifting hot pots on the market that can automatically raise the hot pot frame. Their power unit consists of a motor and multiple gear components. These gear components occupy a significant amount of space, resulting in a larger overall size for the lifting hot pot.
[0003] Therefore, further improvements are necessary. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of automatic lifting hot pot that is simple in structure, low in cost, occupies little space, is easy to use, and highly practical, so as to overcome the shortcomings of the existing technology.
[0005] A novel automatic lifting hot pot designed for this purpose includes a base, a pot body, and a hot pot frame. The base has an inner cavity, the pot body is located at the upper opening of the inner cavity, and the hot pot frame is located inside the pot body. The base is characterized by a lifting device comprising a motor, a crank assembly, a transmission assembly, and a lifting rod. The motor is connected to the transmission assembly via the crank assembly, and the transmission assembly engages with the lifting rod, which abuts against the hot pot frame. The motor drives the crank assembly to move, and the crank assembly, through the transmission assembly, drives the lifting rod to move up and down, thereby causing the lifting rod to move up and down the hot pot frame.
[0006] The crank assembly includes a wheel, a connecting rod, and a rotating arm. A motor drives and connects to the wheel. One end of the connecting rod is rotatably connected to the wheel, and the other end of the connecting rod is rotatably connected to one end of the rotating arm. The other end of the rotating arm is connected to a transmission assembly. The motor drives the wheel to rotate. When the wheel rotates, it drives the rotating arm to rotate through the connecting rod. When the rotating arm rotates, it drives the lifting rod to move up and down through the transmission assembly.
[0007] The lifting device also includes a micro switch and a switching switch. The switching switch is electrically connected to the micro switch. The motor is electrically connected to the micro switch and the switching switch respectively. The wheel is provided with a protrusion. When the wheel rotates, the protrusion periodically switches its action on the micro switch or does not act on it.
[0008] The transmission assembly includes a rotating shaft and a gear component. The other end of the rotating arm is connected to the rotating shaft, the rotating shaft is connected to the gear component, and the gear component is engaged with the lifting rod.
[0009] The other end of the rotating arm is provided with a first gear. The transmission assembly includes a second gear, a rotating shaft and a gear component. The first gear and the second gear mesh with each other. The second gear is connected to the rotating shaft. The rotating shaft is connected to the gear component. The gear component is engaged with the lifting rod.
[0010] The gear assembly includes a third gear and a fourth gear that mesh with each other. The third gear is connected to the rotating shaft. A rack is provided on the lifting rod. The fourth gear meshes with the rack.
[0011] The top of the hot pot rack extends upwards and is equipped with a lifting plate. The upper end of the lifting rod rests on the lifting plate. When the lifting rod moves up and down, it drives the hot pot rack to move up and down through the lifting plate.
[0012] The upper end of the lifting plate extends out of the pot body and is provided with an outwardly extending flange. The upper end of the lifting rod is provided with a first plane, and the bottom of the flange is provided with a second plane. The upper end of the lifting rod abuts against the second plane of the lifting plate through the first plane.
[0013] The gear components are respectively set at both ends of the rotating shaft, and the lifting plate and lifting rod are respectively set on both sides of the hot pot frame. The lifting plate, lifting rod and gear components correspond one to one.
[0014] The motor and crank assembly are located on one side of the inner cavity, the rotating shaft runs laterally through the inner cavity, and the gear assembly and lifting rod are located on both sides of the inner cavity.
[0015] This utility model of an automatic lifting hot pot utilizes a motor, crank assembly, transmission assembly, and lifting rod. The motor drives the crank assembly, which in turn drives the lifting rod to move up and down via the transmission assembly. This lifting rod, in turn, drives the hot pot frame to move up and down, thus achieving automatic lifting of the hot pot frame and making the lifting hot pot more convenient to use. Furthermore, the transmission via the crank assembly improves transmission efficiency, and the crank assembly is relatively small, thus occupying less space and reducing the overall size of the lifting hot pot.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] First embodiment:
[0027] See Figures 1-3 , Figures 6-12 This novel automatic lifting hot pot includes a base 1, a pot body 2, and a hot pot frame 3. The base 1 has an inner cavity 4, the pot body 2 is located at the upper opening of the inner cavity 4, and the hot pot frame 3 is located inside the pot body 2. The base 1 is equipped with a lifting device, which includes a motor 5, a crank assembly, a transmission assembly, and a lifting rod 8. The motor 5 is connected to the transmission assembly through the crank assembly, and the transmission assembly is engaged with the lifting rod 8. The lifting rod 8 abuts against the hot pot frame 3. The motor 5 drives the crank assembly to move, and the crank assembly drives the lifting rod 8 to move up and down through the transmission assembly. In turn, the lifting rod 8 drives the hot pot frame 3 to move up and down on the pot body 2, realizing the separation or immersion of food from the soup base. The pot body 2 is used to hold the soup base, and the hot pot frame 3 is used to hold the food.
[0028] The crank assembly includes a wheel 11, a connecting rod 12, and a rotating arm 15. A motor 5 drives and connects to the wheel 11. One end of the connecting rod 12 is rotatably connected to the wheel 11, and the other end of the connecting rod 12 is rotatably connected to one end of the rotating arm 15. The other end of the rotating arm 15 is connected to a transmission assembly. The motor 5 drives the wheel 11 to rotate. When the wheel 11 rotates, it drives the rotating arm 15 to rotate through the connecting rod 12. When the rotating arm 15 rotates, it drives the lifting rod 8 to move up and down through the transmission assembly.
[0029] When the motor 5 drives the crank assembly to rotate, the crank assembly first drives the lifting rod 8 to rise through the transmission assembly, and then the crank assembly continues to rotate, and then the crank assembly drives the lifting rod 8 to fall through the transmission assembly, and so on.
[0030] The transmission assembly 7 includes a rotating shaft 16 and a gear component. The other end of the rotating arm 15 is connected to the rotating shaft 16. The rotating shaft 16 is connected to the gear component. The gear component is engaged with the lifting rod 8. The rotating shaft 16 is rotatably mounted on the base 1.
[0031] The gear assembly includes a third gear 21 and a fourth gear 22 that mesh with each other. The third gear 21 is connected to the rotating shaft 16. A rack 23 is integrally provided at the lower part of the lifting rod 8. The fourth gear 22 meshes with the rack 23. The motor 5 drives the rotating wheel 11 to rotate. When the rotating wheel 11 rotates, it drives the rotating arm 15 to rotate back and forth through the connecting rod 13. The rotating arm 15 drives the third gear 21 to rotate back and forth through the rotating shaft 16. The third gear 21 drives the fourth gear 22 to rotate back and forth (the rotation directions of the third gear 21 and the fourth gear 22 are opposite). In turn, the fourth gear 22 drives the lifting rod 8 to move up and down. Figure 2 When the rotating arm 15 and the third gear 21 rotate in the direction of the solid arrow, they drive the lifting rod 8 to rise; when the rotating arm 15 and the third gear 21 rotate in the direction of the dashed arrow, they drive the lifting rod 8 to fall.
[0032] The lifting device also includes a micro switch 9 and a switching switch 10. The switching switch 10 is electrically connected to the micro switch 9. The motor 5 is electrically connected to the micro switch 9 and the switching switch 10 respectively. The edge of the rotating wheel 11 is provided with a protrusion 13. When the rotating wheel 11 rotates, the protrusion 13 periodically switches to act on or not act on the micro switch 9 to switch the micro switch 9. When the switching switch 10 and the micro switch 9 switch, the motor 5 is started or stopped, that is, the motor 5 is controlled to work or stop working.
[0033] When the wheel 11 rotates and the protrusion 13 does not act on the micro switch 9, the crank assembly drives the lifting rod 8 to rise through the transmission assembly, thereby driving the hot pot frame 3 to rise; when the wheel 11 rotates and the protrusion 13 acts on the micro switch 9, the crank assembly drives the lifting rod 8 to fall through the transmission assembly, thereby driving the hot pot frame 3 to fall.
[0034] The protrusion 13 extends along the edge of the rotating wheel 11 at an angle of 180°. The micro switch 9 is provided with a trigger part 14. When the rotating wheel 11 rotates, the protrusion 13 periodically switches between acting (pressing) or not acting (not pressing) on the trigger part 14, so that the micro switch 9 is periodically pressed or not pressed when the rotating wheel 11 rotates halfway 180 degrees. The rotating wheel is driven to rotate 360 degrees by the cyclically rotating motor 5. When the rotating wheel 11 rotates halfway 180 degrees, the micro switch 9 is periodically pressed or not pressed. The micro switch 9 and the switching switch 10 are connected by a double-hole wire. Its working mode is cyclic. This structure eliminates the need for a circuit board and a forward and reverse motor, which can greatly reduce costs and make the wiring of the automatic lifting hot pot simpler and easier to connect.
[0035] The changeover switch 10 is equipped with a switchable first contact A and a second contact B, and the micro switch 9 is equipped with a switchable third contact A' and a fourth contact B'. The first contact A is electrically connected to the third contact A', and the second contact B is electrically connected to the fourth contact B'. The changeover switch 10 and the micro switch 9 adopt the single-pole double-throw wiring principle and have a double-hole wiring. Manually controlling the changeover switch 10 can control the cyclic rotation of the motor 5, which is a 220V geared motor.
[0036] The switch 10 is either a rocker switch or an electronic switch, preferably a rocker switch.
[0037] The top of the hot pot frame 3 extends upward and is provided with a lifting plate 24. The upper end of the lifting rod 8 rests on the lifting plate 24. When the lifting rod 8 moves up and down, it drives the hot pot frame 3 to move up and down through the lifting plate 24. The lifting plate 24 is fixed to the top of the hot pot frame 3 with screws.
[0038] The upper end of the lifting plate 24 extends out of the pot body 2 and is provided with an outwardly extending flange 17. The upper end of the lifting rod 8 is provided with a first plane 27, and the bottom of the flange 17 is provided with a second plane 28. The upper end of the lifting rod 8 abuts against the second plane 28 of the lifting plate 13 through the first plane 27.
[0039] The gear components are respectively set at both ends of the rotating shaft 16, and the lifting plate 24 and the lifting rod 8 are respectively set on both sides of the hot pot frame 3. The lifting plate 24, the lifting rod 8 and the gear components correspond one to one.
[0040] The motor 5 and crank assembly are located on one side of the inner cavity 4, without occupying the space in the middle of the inner cavity 4. The space in the middle of the inner cavity 4 is used to install the heating plate. The rotating shaft 16 passes through the inner cavity 4 laterally. The gear component and the lifting rod 8 are respectively located on both sides of the inner cavity 4.
[0041] The outer side of the flange 17 is connected to a handle 29 for lifting the hot pot rack 3.
[0042] Motor 5 and micro switch 9 are fixed on base 1, and switch 10 is fixed on the side of base 1.
[0043] The lifting control method of this novel automatic lifting hot pot includes the following steps:
[0044] 1) When the automatic lifting hot pot is reset, the switch 10 switches to close the first contact A, the micro switch 9 switches to close the fourth contact B', the hot pot frame 3 descends to the lowest position, the circuit composed of switch 10, motor 5 and micro switch 9 is disconnected, the motor 5 stops working, and the automatic lifting hot pot is in the cooking state.
[0045] 2) Manually switch the switch 10 to close the second contact B, and keep the fourth contact B' closed. The circuit consisting of switch 10, motor 5 and micro switch 9 is connected. Motor 5 works and drives the wheel 11 to rotate, so as to drive the hot pot rack 3 to rise. The protrusion 13 does not act on the micro switch 9.
[0046] 3) The rotating wheel 11 rotates 180°, and the protrusion 13 acts on the micro switch 9. The micro switch 9 switches and closes the third contact A'. The circuit composed of the switching switch 10, the motor 5 and the micro switch 9 is disconnected. The motor 5 stops working, and the hot pot rack 3 rises to the highest position and remains in the raised state. The automatic lifting hot pot is in the food-picking state.
[0047] 4) Manually switch the switch 10 to close the first contact A, while keeping the third contact A' closed. The circuit consisting of switch 10, motor 5, and micro switch 9 is connected. Motor 5 operates and drives the rotating wheel 11 to rotate, thereby driving the hot pot rack 3 to begin descending. The protrusion 13 continues to act on the micro switch 9. The rotating wheel 11 rotates 180°, and the hot pot rack 3 descends to the lowest position. The automatic lifting hot pot returns to the reset state and returns to step 1).
[0048] 5) Repeat steps 1) to 4) in a loop.
[0049] The operation or stop of the motor 5 is controlled by turning on or off the circuit composed of switch 10, motor 5 and micro switch 9, so there is no need to use a circuit board to control the motor 5.
[0050] Second embodiment:
[0051] See Figure 1 , Figures 4-12 The difference between this novel automatic lifting hot pot and the first embodiment is that:
[0052] The other end of the rotating arm 15 is integrally provided with a first gear 19. The transmission assembly 7 includes a second gear 20, a rotating shaft 16 and a gear component. The first gear 19 and the second gear 20 mesh with each other. The second gear 20 is connected to the rotating shaft 16. The rotating shaft 16 is connected to the gear component. The gear component is engaged with the lifting rod 8. The rotating shaft 16 is rotatably mounted on the base 1.
[0053] The gear assembly includes a third gear 21 and a fourth gear 22 that mesh with each other. The third gear 21 is connected to the rotating shaft 16. A rack 23 is integrally provided at the lower part of the lifting rod 8. The fourth gear 22 meshes with the rack 23. The motor 5 drives the rotating wheel 11 to rotate. When the rotating wheel 11 rotates, it drives the rotating arm 15 to rotate back and forth through the connecting rod 13. The rotating arm 15 drives the first gear 19 to rotate back and forth. The first gear 19 drives the second gear 20 to rotate back and forth (the rotation directions of the first gear 19 and the second gear 20 are opposite). The second gear 20 drives the third gear 21 to rotate back and forth through the rotating shaft 16. The third gear 21 drives the fourth gear 22 to rotate back and forth (the rotation directions of the third gear 21 and the fourth gear 22 are opposite). In turn, the fourth gear 22 drives the lifting rod 8 to move up and down. Figure 4 When the rotating arm 15 and the third gear 21 rotate in the direction of the solid arrow, they drive the lifting rod 8 to rise; when the rotating arm 15 and the third gear 21 rotate in the direction of the dashed arrow, they drive the lifting rod 8 to fall.
