[0002] With the improvement of people's living standards, various cooking devices in modern kitchens are increasingly widely used, such as sugar removal electric rice cookers, pressure cookers, lifting chafing dishes, electric steamers, etc. In these cooking devices, in order to achieve more convenient operation experience and strengthen functionality, push rod (top rod) lifting devices are widely used. The lifting mechanism of the push rod is mainly used to adjust the height of the lifting basin in the pot body to adjust the height of the food materials in the pot body to meet different cooking needs. However, the push rod lifting device on the market still has some problems that need to be optimized in terms of structure design and user experience.

[0003] The push rod lifting mechanism in the current cooking device usually adopts a motor drive method to complete the lifting action of the push rod. The working principle is to convert the rotary motion of the motor into the linear motion of the push rod through the driving power output of the motor, using gears, pulleys or other transmission devices. Although this design achieves the lifting function of the push rod, it also has the following disadvantages and limitations.

[0004] Among them, the motor must be closely combined with the push rod device, and the power transmission can only be completed through the bridging of gears or other mechanical connecting pieces. This integrated design increases the complexity of the device, which is not conducive to the separation operation of the device, limits the user's convenience, and at the same time, this integrated design cannot meet the demand of functional modularization, which is not conducive to the expansion and compatibility of functions.

[0005] In addition, in some cooking scenarios, the push rod lifting device needs to be in contact with liquid. In the traditional structure, the integrated design of the motor and the push rod device makes it difficult to achieve effective waterproof sealing of the motor, which may cause water leakage hazards and even cause electric shock problems, posing a great safety hazard.

[0006] And because the motor and the push rod part are closely coupled, any damage to any part will affect the normal operation of the entire device, making maintenance and replacement more troublesome. In addition, this design may cause wear and tear of the gear or pulley transmission parts due to friction, aging, etc. during long-term use, increasing the subsequent maintenance cost, and being not conducive to the user's quick disassembly and cleaning. The forced combination of the motor part and the push rod also limits the flexibility of the device operation, which is not conducive to improving the user experience.

[0007] The utility model is proposed to solve the problems in the prior art. UTILITY MODEL CONTENTS

[0032] The embodiment of the utility model will be described in detail below with reference to the drawings.

[0033] Example 1:

[0034] As Figures 1 to 3 The magnetic drive mechanism of the embodiment includes a drive assembly 1 and a lifting assembly 2, which are independent of each other. The drive assembly 1 is located on the outside of the bottom of the pot 3, and the lifting assembly 2 is located on the inside of the bottom of the pot 3. The lifting assembly 2 includes an assembly housing 21, and a magnetically controlled component 22 is arranged in the assembly housing 21. The magnetically controlled component 22 is located at the bottom of the assembly housing 21.

[0035] The assembly housing 21 is movably connected with a lifting rod 23, and the lifting rod 23 is in transmission connection with the magnetically controlled component 22.

[0036] The drive assembly 1 includes a drive motor 11 and a magnetic drive element 12 arranged on the output end of the drive motor 11. The magnetic drive element 12 is correspondingly arranged with the magnetically controlled component 22, and the assembly housing 21 can be assembled in the pot 3 through the magnetic attraction between the magnetic drive element 12 and the magnetically controlled component 22.

[0037] The drive motor 11 can drive the magnetic drive element 12 to rotate, so that the magnetic drive element 12 drives the magnetically controlled component 22 to rotate, so that the magnetically controlled component 22 drives the lifting rod 23 to ascend and descend on the assembly housing 21.

[0038] The embodiment proposes a push rod (lifting rod) lifting device based on a magnetic drive mechanism, which mainly includes two independent components of a drive assembly and a lifting assembly. The power is transmitted in the air through magnetic drive technology. This design avoids the inherent shortcomings of mechanical connection between the motor and the lifting rod in the traditional push rod lifting device, and has obvious innovation and advantages.

[0039] Specifically, the drive motor 11 in the drive assembly 1 drives the magnetic drive element 12 to rotate, and the magnetic drive element 12 and the magnetically controlled component 22 in the lifting assembly 2 interact with each other through magnetic force, so that the magnetically controlled component 22 moves in the assembly housing 21. The magnetically controlled component 22 drives the lifting rod 23 to ascend and descend along the assembly housing 21, thereby realizing the lifting function in the pot.

[0040] The driving assembly and the lifting assembly are independent of each other, the driving assembly is located outside the pot body, and power transmission is achieved through magnetic force between the driving assembly and the lifting assembly without mechanical connection. Such a split design avoids the mechanical coupling problem between the motor and the push rod in the traditional push rod lifting device, facilitates separation operation and independent maintenance.

[0041] Moreover, power is transmitted through magnetic attraction between the magnetic driving member and the magnetic controlled component, avoiding the problems such as wear, noise and complex maintenance that may occur in the traditional gear and pulley transmission, while the reliability and durability of the device are enhanced.

[0042] Specifically, the driving motor 11 and the electrical components are completely located outside the pot body, and the magnetic controlled component is located inside the pot body, avoiding the risk of direct contact of the motor with the internal environment of the cooking device, eliminating safety hazards such as water leakage and electric shock, and being particularly suitable for application scenarios that need to be in direct contact with liquid, such as lifting hot pot, desugar electric rice cooker, pressure cooker, etc.

[0043] Specifically, the lifting assembly is assembled in the pot body through magnetic attraction, without the need for complex mechanical fixing tools, and users can quickly disassemble, clean, maintain or replace it.

[0044] The split design of the driving assembly and the lifting assembly has high modularity, facilitating the development of lifting devices of different specifications and functions to meet diversified application needs. For example, by adjusting the design parameters of the magnetic driving member and the magnetic controlled component, higher lifting precision or greater lifting force can be achieved.

[0045] The magnetic drive mechanism is suitable for various cooking scenarios that require lifting function, such as food material lifting adjustment in lifting hot pot, rice and water lifting in desugar electric rice cooker, steaming plate height adjustment in steamer or pressure cooker, etc.

[0046] As shown in Figures 1 to 3 The magnetic controlled component 22 of the present embodiment includes a controlled magnet 221, and the bottom of the controlled magnet 221 is connected to the inside of the bottom of the assembly housing 21 by a point connection. Specifically, at least a single point connection is used between the controlled magnet 221 and the assembly housing 21 to minimize friction between them during movement.

[0047] Specifically, the bottom surface of the controlled magnet 221 only contacts the assembly housing 21 through one or a few points, and by reducing the physical contact area between the controlled magnet 221 and the assembly housing 21 instead of large-area contact, the friction surface is minimized, the friction resistance between them is reduced, and the contact friction between the controlled magnet 221 and the assembly housing 21 during movement is significantly reduced, thereby reducing power loss and improving the energy efficiency ratio of the lifting device.

[0048] The point connection design reduces the mechanical resistance caused by large-area contact in traditional designs, enabling the magnetic driving part 12 to more efficiently drive the controlled magnet 221 to rotate and in turn move the lifting rod 23.

[0049] Further, the point connection structure maintains the stability of the main body while enhancing the flexibility of the moving part, enabling the magnetically controlled part to more smoothly respond to the rotation or movement of the magnetic driving part 12.

[0050] Preferably, the connection point can be achieved by designing a small number of support bumps or rolling parts (such as small balls) at the bottom of the assembly shell 21, thereby defining the movement trajectory of the controlled magnet 221.

[0051] Preferably, the bottom of the controlled magnet 221 can also be designed with specific bumps or treated with wear-resistant materials to further reduce friction.

[0052] Further, due to the significant reduction in frictional contact area, the wear between the controlled magnet 221 and the assembly shell 21 is reduced, thereby prolonging the service life of both. In particular, in long-term use or high-frequency lifting scenarios, this point connection structure significantly reduces maintenance requirements, improving the stability and durability of the device.

[0053] The point connection method has the advantages of simpler structure and lower manufacturing cost, not only reducing the overall production cost of the device, but also reducing the complexity of subsequent maintenance.

[0054] Preferably, the controlled magnet 221 is in the shape of a sphere (such as a round ball or an oval ball) or a gyroscope, etc., to form a point connection with the assembly shell 21.

[0055] Preferably, the controlled magnet 221 is designed as a sphere (such as a standard round ball or an oval ball), which only contacts the bottom of the assembly shell 21 at a single point. The curved surface structure of the sphere naturally adapts to forces in different directions. The curved surface of the sphere makes it have less resistance when rotating or moving, reduces friction, and the point contact is more accurate, enabling the magnetically controlled part to have a more stable movement trajectory in the assembly shell.

[0056] In other embodiments, the controlled magnet 221 is designed as an oval ball, which is a design similar to a sphere but slightly flattened. The oval ball can maintain point connection while increasing contact stability. The oval ball has higher stability when subjected to forces in multiple directions, especially in larger load scenarios.

[0057] In other embodiments, the controlled magnet 221 is designed in a shape similar to a gyroscope, with a pointed or conical bottom, so that it forms a point contact with the assembly shell 21, while the overall has good rotational balance. The pointed bottom of the gyroscope-shaped design has a smaller contact area, further reducing friction, making rotation or linear motion more smooth and easy. The gyroscope-shaped design also naturally forms a self-guiding function, improving the accuracy of movement. The appropriate design can be selected according to actual needs.

[0058] As shown in Figures 1 to 3 The magnetic controlled component 22 of the embodiment includes a controlled magnet 221 and a drive rod 222, which is threadedly connected with the lifting rod 23.

[0059] Specifically, the threaded part of the drive rod 222 is threadedly connected with the lifting rod 23, and the rotation of the controlled magnet 221 is converted into linear motion of the lifting rod 23 through the drive rod 222. This threaded transmission mechanism converts rotary motion into linear motion, achieving the lifting adjustment of the lifting rod. The threaded transmission converts rotary motion into linear motion, which has a more precise motion ratio and can effectively control the height of the lifting rod.

[0060] Preferably, the threaded transmission has high mechanical efficiency and can withstand large load pressure. Even if the lifting rod needs to carry heavy objects, the device can still maintain stable lifting performance.

[0061] Moreover, the threaded structure naturally has self-locking performance (especially when using trapezoidal threads or ball screws), which can keep the position of the lifting rod unchanged without external driving force, preventing accidental sliding and improving the safety of the device.

[0062] Preferably, in other embodiments, the controlled magnet 221 and the lifting rod 23 can also use other forms to achieve driving and lifting, such as:

[0063] The inclined groove-guide pin mechanism is designed with a helical inclined groove distributed circumferentially on the side or top of the drive rod 222, and a guide pin is fixed on the lifting rod 23. The guide pin is embedded in the helical inclined groove of the drive rod 222. When the drive rod 222 rotates, the helical inclined groove pushes the guide pin to move along the inclined groove, thereby driving the lifting rod 23 to move vertically.

[0064] The eccentric wheel-slide block mechanism connects the bottom or middle of the lifting rod 23 through the eccentric structure of the drive rod 222, and designs a guide rail or sliding groove on the lifting rod 23 to restrict its movement only in the vertical direction. When the drive rod 222 rotates, the eccentric wheel moves up and down due to the change of eccentric distance, driving the lifting rod 23 to move up and down.

[0065] Gear-rack mechanism, part of the driving rod 222 is designed as a gear, one side or inside of the lifting rod 23 is designed as a rack shape, when the driving rod 222 rotates, the gear drives the rack to move in the vertical direction, thereby driving the lifting rod 23 to lift.

[0066] Chute-slide mechanism, an inclined or curved chute is designed on the top or side of the driving rod 222, a slide block is designed on the bottom of the lifting rod 23, which is in contact with the chute, when the driving rod 222 rotates, the inclined angle of the chute drives the slide block to move in the vertical direction, thereby achieving the lifting of the lifting rod 23.

[0067] Not limited to the above design, suitable design can be selected according to actual needs.

[0068] As shown in Figures 1 to 3 , the assembly housing 21 and the lifting rod 23 of the embodiment are provided with a limiting assembly 226 capable of limiting the circumferential rotation of the lifting rod 23, to ensure that the rotation of the driving rod 222 can normally drive the lifting rod 23 to lift.

[0069] As shown in Figures 3 to 5 , the limiting assembly 226 of the embodiment includes a positioning clamping groove 2261 and a positioning clamping block 2262 corresponding thereto, when the lifting rod 23 is assembled into the assembly housing 21, the positioning clamping block 2262 is clamped into the positioning clamping groove 2261, to realize that the circumferential rotation freedom of the lifting rod 23 is constrained, and only axial sliding is allowed.

[0070] In other embodiments, the limiting assembly 226 includes two parallel guide rods arranged in the vertical direction on the assembly housing 21, and the lifting rod 23 is designed with a corresponding sliding sleeve or guide hole, which is sleeved on the guide rod, to realize that the circumferential rotation freedom of the lifting rod 23 is constrained, and only axial sliding is allowed, and suitable design can be selected according to actual needs.

[0071] Preferably, in other embodiments, the limiting assembly 226 includes a special-shaped hole provided on the assembly housing 21, the shape of the special-shaped hole is polygonal or elliptical, and the cross-sectional shape of the lifting rod 23 matches the shape of the special-shaped hole, to realize that the circumferential rotation freedom of the lifting rod 23 is constrained, and only axial sliding is allowed.

[0072] As shown in Figure 6 , the cooking device of the embodiment includes a pot body 3, a base 4, a lifting disc, and a magnetic driving mechanism as described in any of the above, the lifting assembly 2 is located in the pot body 3, the driving assembly 1 is provided in the base 4, and the top of the lifting rod 23 abuts against the lifting disc.

[0073] Through the magnetic driving non-contact structure, the lifting disc can be smoothly lifted to meet the cooking state adjustment needs of different food materials.

[0074] The driving assembly and the lifting assembly are driven through magnetic coupling, without mechanical penetration structure, improving the sealing of the lifting device, preventing water vapor or oil stains from entering the base, and the lifting disc and the pot body can be designed in a modular manner, facilitating disassembly and cleaning, without threaded connection, reducing sanitary dead angles, and meeting the cleaning requirements of modern kitchens.

[0075] In combination with the pot body design, various cooking functions such as steaming, boiling and stewing can be realized, and the lifting disc can be matched with different accessories (such as a steaming drawer and a tray), further expanding the application scenarios of the device.

[0076] The cooking device is a lifting hot pot, a sugar-removing electric rice cooker, a steamer or a pressure cooker, and a suitable design can be selected according to actual needs.

[0077] Embodiment 2:

[0078] As shown in Figure 4 The difference between this embodiment and embodiment 1 is that:

[0079] The magnetically controlled component 22 of this embodiment further includes a rotating assembly 223, which is located between the controlled magnet 221 and the assembly shell 21.

[0080] Preferably, the rotating assembly 223 of this embodiment includes a rotating disc 224, the bottom of which is connected to the inner wall of the bottom of the assembly shell 21, and the top of which is connected to the bottom of the controlled magnet 221.

[0081] Specifically, the driving assembly 1 is located in the base 4, generates a rotating magnetic field through a rotating driving magnet, and the magnetic coupling between the driving magnet and the controlled magnet 221 synchronously rotates the controlled magnet.

[0082] The rotating disc 224 serves as a support and rotating component of the controlled magnet, carries the controlled magnet and realizes stable rotation through connection with the assembly shell 21, and the bottom of the rotating disc is connected to the assembly shell through a bearing or a friction interface, reducing the rotating resistance; the top is connected to the controlled magnet through a fixed manner, transmitting the rotating force generated by magnetic coupling to the controlled magnet.

[0083] The rotation of the controlled magnet 221 drives the lifting rod 23 to move up and down through a mechanical transmission structure (such as a driving screw 222 or other transmission mechanism).

[0084] The rotating assembly ensures smooth and stable rotation of the controlled magnet in the assembly shell, while maintaining the smoothness and stability of the lifting process.

[0085] Preferably, the rotating disc 224 in the rotating assembly is connected to the inner wall of the assembly shell through the bottom, providing stable support and avoiding shaking or deviation of the controlled magnet during rotation.

[0086] Preferably, the bottom of the turntable 224 can be connected to the assembly housing through a high-performance bearing or a low-friction material, which can effectively reduce rotational friction and improve transmission efficiency.

[0087] The design of turntable 224 cleverly connects the controlled magnet 221 to the assembly housing 21, forming a compact rotating unit without increasing the additional assembly volume.

[0088] Furthermore, the turntable 224 can further restrict the controlled magnet 221, preventing it from moving up and down along the axial direction of the assembly housing 21, ensuring that the controlled magnet 221 can normally drive the drive rod 222, thereby driving the lifting rod 23 to move up and down.

[0089] Example 3:

[0090] like Figure 5 As shown, the difference between this embodiment and Embodiment 2 is that:

[0091] In this embodiment, the rotating assembly 223 is located between the drive rod 222 and the assembly housing 21.

[0092] Preferably, the rotating assembly 223 includes a bearing 225, and the drive rod 222 includes a threaded section 2221 and a bearing connecting section 2222 arranged sequentially from top to bottom. The bearing 225 is located between the outer wall of the bearing connecting section 2222 and the inner wall of the assembly housing 21.

[0093] When the drive assembly 1 drives the controlled magnet 221 to rotate through the magnetic coupling mechanism, the rotational force is further transmitted to the drive rod 222. The drive rod 222 converts the rotational motion into the linear motion of the lifting rod 23 through the threaded engagement of its threaded section 2221 with the lifting rod 23, thereby driving the lifting plate to move up and down.

[0094] The bearing connection section 2222 of the drive rod 222 is connected to the assembly housing 21 through the bearing 225. The bearing 225 supports the rotation of the drive rod 222 through rolling friction, while reducing frictional resistance during rotation and improving transmission efficiency.

[0095] Furthermore, the use of bearing 225 to support the rotation of drive rod 222 effectively avoids shaking and deviation, ensuring a smoother driving process for lifting rod 23.

[0096] Furthermore, the outer side of the bearing 225 is fixedly connected to the inner wall of the assembly housing 21, so that the bearing 225 can further restrict the drive rod 222 to restrict the controlled magnet 221, prevent the controlled magnet 221 from rising and falling along the axial direction of the assembly housing 21, and ensure that the controlled magnet 221 can normally drive the drive rod 222, thereby driving the lifting rod 23 to rise and fall.

[0097] Example 4:

[0098] The difference between the embodiment and embodiment 1 is that:

[0099] The outer side of the assembly shell 21 is further provided with a connecting member capable of being connected with the pot body 3, the main function of the connecting member is to assist the magnetic driving member 12 and the magnetic controlled part 22, and further firmly fix the assembly shell 21 in the pot body 3, so as to prevent the loosening or falling of the assembly shell due to vibration, high temperature or other external force during the lifting operation or the cooking process.

[0100] The connecting member can adopt various connection modes, for example:

[0101] The buckle type connection is that the outer side of the assembly shell 21 is designed with elastic buckles, which can be buckled with the inner wall or special clamping groove of the pot body 3, so as to realize quick installation and tight fixing.

[0102] The threaded connection is that the outer side of the assembly shell 21 is designed with threads, which are screwed and connected with the corresponding threaded interfaces of the pot body 3.

[0103] The clamping groove connection is that the outer side of the assembly shell 21 is designed with an annular clamping groove, and a groove with a sealing ring is designed at the corresponding position of the pot body 3, after the assembly shell is inserted into the pot body, the clamping groove is tightly combined with the groove.

[0104] The user can select the appropriate design according to the actual needs.

[0105] The above is only to further illustrate the technical content of the utility model by means of embodiments, so as to make the reader more easily understand, but it does not mean that the embodiments of the utility model are limited to this, any technical extension or re-creation made according to the utility model is also protected by the utility model.
