Description

Technical Field

[0001] This utility model relates to the field of hot pot technology, and in particular to a lifting hot pot. Background Technology

[0002] Chinese patent document CN217959665U, published on December 6, 2022, discloses a lifting hot pot, including a pot body, a filter basket, and a lifting mechanism. The filter basket is disposed within the pot body. The lifting mechanism includes a drive component, a lead screw, a nut, and a first lifting component. The lead screw is arranged along the vertical direction of the pot body. The drive component drives the lead screw to rotate. The nut is sleeved on the lead screw and can move along the lead screw when it rotates to achieve lifting and lowering. The first lifting component is connected to the nut and can rise and fall with the nut. The first lifting component supports the side of the filter basket to drive the filter basket to rise and fall. This lifting hot pot uses a lead screw, nut, and gear transmission method to achieve the lifting and lowering of the filter basket (i.e., the hot pot frame). The manufacturing cost is relatively high, and the lifting and lowering of the filter basket is not stable and is prone to shaking.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a lifting hot pot with a simple structure, low manufacturing cost, smooth lifting, convenient use, and strong practicality, so as to overcome the shortcomings of the existing technology.

[0005] A 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, which includes a motor, a crank assembly, a sliding member, a transmission assembly, and a lifting plate. The motor is connected to the sliding member via the crank assembly, and the sliding member is connected to the lifting plate via the transmission assembly. The lifting plate is connected to the hot pot frame. The motor drives the sliding member to slide linearly back and forth via the crank assembly. When the sliding member slides linearly back and forth, it drives the lifting plate to move up and down via the transmission assembly, thereby causing the hot pot frame to move up and down.

[0006] The inner cavity is provided with a guide groove, and the sliding part is provided with a sliding boss. The sliding part is slidably mounted on the guide groove through the sliding boss.

[0007] The crank assembly includes a wheel and a connecting rod. A motor drives 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 a slider. The motor drives the wheel to rotate in one direction, and when the wheel rotates, it drives the slider to slide linearly back and forth through the connecting rod.

[0008] The transmission assembly includes a transmission gear, a transmission shaft, and gear components. Transmission teeth are provided on the sliding boss, and the transmission teeth mesh with the transmission gear. The transmission gear is sleeved on the transmission shaft, and the gear components are respectively connected to both ends of the transmission shaft. The gear components are engaged with the lifting plate.

[0009] The gear assembly includes a first gear, a second gear, and a third gear that mesh in sequence. The two ends of the transmission shaft are connected to the first gear, and a rack is provided on the lifting plate. The third gear meshes with the rack.

[0010] The lifting device also includes a micro switch and a lifting switch that are electrically connected to each other. The motor is electrically connected to the micro switch and the lifting switch respectively. The rotating wheel is provided with a protrusion. When the rotating wheel rotates, the protrusion periodically switches its action on or off the micro switch to switch the state of the micro switch. The motor is started and stopped when the lifting switch and the micro switch switch switch.

[0011] The hot pot frame has lifting connecting plates on both sides, with insertion holes on the lifting connecting plates and insertion posts on the top of the lifting plates. The insertion posts and insertion holes are interlocked to connect the lifting plates and the hot pot frame.

[0012] An electrical box is installed in the inner cavity. The electrical box includes a box body and a cover that fits on the box body. The box body has a movable cavity and a mounting cavity. The sliding part and the transmission gear are located in the movable cavity. The motor is installed in the mounting cavity. The transmission shaft passes through the box body. The micro switch is fixed on the cover.

[0013] The inner cavity has mounting boxes on both sides. The lifting plate and gear components are installed in the mounting boxes. The mounting boxes are equipped with lifting guide grooves. The lifting plate moves up and down on the lifting guide grooves. When the lifting plate moves upward, it extends out of the mounting box.

[0014] A heating plate is installed at the bottom of the pot body, an electric control board is installed on the inner cavity, and a power switch for adjusting the heat of the heating plate is installed on the outside of the base. The electric control board is electrically connected to the heating plate and the power switch respectively.

[0015] This utility model of a lifting hot pot uses a crank assembly and gear rack transmission to achieve the up-and-down lifting of the hot pot frame, eliminating the traditional screw and nut transmission method, which can reduce the manufacturing cost of the lifting hot pot. In addition, by setting a sliding component, the motor drives the sliding component to slide linearly back and forth through the crank assembly. When the sliding component slides linearly back and forth, it drives the lifting plate to move up and down through the transmission assembly. The sliding component is slidably mounted on the guide groove through a sliding boss. The linear movement of the sliding component and the limiting of the guide groove can improve the stability of the transmission and avoid swaying and deviation when the hot pot frame is raised and lowered, thus ensuring the stability of the hot pot frame lifting.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See Figures 1-15This 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 sliding member 6, a transmission assembly, and a lifting plate 7. The motor 5 is connected to the sliding member 6 via the crank assembly, and the sliding member 6 is connected to the lifting plate 7 via the transmission assembly. The lifting plate 7 is connected to the hot pot frame 3. The motor 5 drives the sliding member 6 to slide linearly back and forth via the crank assembly. When the sliding member 6 slides linearly back and forth, it drives the lifting plate 7 to move up and down via the transmission assembly. In turn, the lifting plate 7 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.

[0030] The inner cavity 4 is provided with a guide groove 8, and the sliding member 6 is provided with a sliding boss 9. The sliding member 6 is slidably mounted on the guide groove 8 through the sliding boss 9, so that the sliding member 6 can only make horizontal linear reciprocating motion in one direction.

[0031] The crank assembly includes a wheel 10 and a connecting rod 11. A motor 5 drives and connects to the wheel 10. One end of the connecting rod 11 is rotatably connected to the wheel 10, and the other end of the connecting rod 11 is rotatably connected to the slider 6. The motor 5 drives the wheel 10 to rotate in one direction. When the wheel 10 rotates, it drives the slider 6 to slide linearly back and forth through the connecting rod 11, and the connecting rod 11 performs a reciprocating oscillating motion. The motor is a unidirectional rotary motor.

[0032] When the motor 5 drives the crank assembly to rotate, the crank assembly first drives the lifting plate 7 to rise through the sliding member 6 and the transmission assembly. Then the crank assembly continues to rotate, and then the crank assembly drives the lifting plate 7 to fall through the sliding member 6 and the transmission assembly, and so on.

[0033] The transmission assembly includes a transmission gear 12, a transmission shaft 13, and a gear component. A transmission tooth 38 is provided on the sliding boss 9. The transmission tooth 38 meshes with the transmission gear 12. The transmission gear 12 is sleeved on the transmission shaft 13. The gear component is connected to both ends of the transmission shaft 13. The gear component engages with the lifting plate 7. The transmission shaft 13 is rotatably mounted on the base 1. The sliding member 6 is equivalent to a rack.

[0034] The gear assembly includes a first gear 14, a second gear 15, and a third gear 16 that mesh in sequence. The two ends of the transmission shaft 13 are respectively connected to the first gear 14. A rack 17 is integrally provided on the lifting plate 7. The third gear 16 meshes with the rack 17. The motor 5 drives the rotating wheel 10 to rotate in one direction. When the rotating wheel 10 rotates, it drives the sliding member 6 to slide linearly back and forth through the connecting rod 11. The sliding member 6 drives the transmission gear 12 to rotate back and forth. The transmission gear 12 drives the transmission shaft 13 to rotate back and forth. The transmission shaft 13 drives the first gear 14 to rotate back and forth. The first gear 14 sequentially drives the second gear 15 and the third gear 16 to rotate back and forth. In turn, the third gear 16 drives the lifting plate 7 to move up and down. Figure 4 The arrows indicate the direction of movement of each component when the lifting plate 7 rises.

[0035] The lifting device also includes a micro switch 18 and a lifting switch 19 that are electrically connected to each other. The motor 5 is electrically connected to the micro switch 18 and the lifting switch 19 respectively. The edge of the wheel 10 is provided with a protrusion 31. When the wheel 10 rotates, the protrusion 31 periodically switches between acting on or not acting on the micro switch 18 to switch the state of the micro switch 18. When the lifting switch 19 and the micro switch 18 switch, the motor 5 is started or stopped, that is, the motor 5 is controlled to work or stop working.

[0036] When the wheel 10 rotates and the protrusion 31 does not act on the micro switch 18, the crank assembly drives the lifting plate 7 to rise through the sliding member 6 and the transmission assembly, thereby driving the hot pot frame 3 to rise; when the wheel 10 rotates and the protrusion 31 acts on the micro switch 18, the crank assembly drives the lifting plate 7 to fall through the sliding member 6 and the transmission assembly, thereby driving the hot pot frame 3 to fall.

[0037] The protrusion 31 extends along the edge of the rotating wheel 10 at an angle of 180°. A trigger part 32 is provided on the micro switch 18. When the rotating wheel 10 rotates, the protrusion 31 periodically switches between acting (pressing) or not acting (not pressing) on ​​the trigger part 32, so that the micro switch 18 is periodically pressed or not pressed when the rotating wheel 10 rotates halfway through 180 degrees. The rotating wheel 10 is driven to rotate 360 ​​degrees by the cyclically rotating motor 5. When the rotating wheel 10 rotates halfway through 180 degrees, the micro switch 18 is periodically pressed or not pressed. The micro switch 18 and the lifting switch 19 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.
