[0069] The top suction type tea kettle according to the embodiments of the utility model is described in detail below with reference to the drawings.

[0070] Referring to Figures 1 to 12 As shown in the drawings, the top suction type tea kettle provided by the embodiments of the utility model comprises a kettle body 100, a tea bin assembly 200 and a kettle cover 300.

[0071] Specifically, the kettle body 100 is usually made of glass, ceramic, metal or the like, has a certain volume, and is used for containing brewed tea water. A spout can be arranged on the kettle body 100, which is used for pouring out the tea water.

[0072] The tea bin assembly 200 includes a bin body 20, a water outlet nozzle 21, and a magnetic valve core 22. The bin body 20 is used for containing tea leaves and brewing tea water. The bin body 20 is arranged in the kettle opening of the kettle body 100. The bin body 20 is made of high-temperature-resistant food-grade materials such as glass, ceramic, stainless steel, etc. The bin body 20 has a proper capacity space. The top of the bin body 20 is provided with an opening for conveniently adding tea leaves.

[0073] The water outlet nozzle 21 is arranged at the bottom of the bin body 20 and is used for discharging liquid in the bin body 20. The water outlet nozzle 21 and the bottom of the bin body 20 can be sealingly connected, or the water outlet nozzle 21 and the bottom of the bin body 20 are designed in an integrated manner to ensure that the tea water flows out of the water outlet nozzle 21 into the kettle body 100 during use.

[0074] The magnetic valve core 22 is arranged on the water outlet nozzle 21 and can slide in a vertical direction between an open position and a closed position. When the magnetic valve core 22 is in the closed position, the magnetic valve core 22 closes the water outlet nozzle 21, so that the tea water is kept in the bin body 20, which is usually used for tea brewing. When the magnetic valve core 22 is in the open position, the magnetic valve core 22 opens the water outlet nozzle 21. After the tea water in the bin body 20 is brewed for the required time, the water outlet nozzle 21 is controlled to be opened, so that the tea water flows out into the kettle body 100 below and is then poured out from the kettle body 100 for drinking.

[0075] The kettle cover 300 includes a cover body 30, a first magnet 31, and a driving member 32. The cover body 30 is arranged on the top of the bin body 20. The cover body 30 can be made of glass, ceramic, metal, wood or the like, and has a disc-shaped structure with a size matching the opening of the top of the tea bin.

[0076] The first magnet 31 is arranged in the cover body 30, and has an axis extending in a horizontal direction and opposite magnetic poles in a radial direction. This arrangement allows the N and S poles of the first magnet 31 to change direction when the first magnet 31 rotates in a vertical plane. The first magnet 31 can be a cylindrical radial magnet. The magnetic strength of the first magnet 31 should be selected according to actual use requirements to ensure that it can form an effective magnetic force with the magnetic valve core 22 at the bottom of the tea bin.

[0077] The driving component 32 is disposed on the cover 30 and connected to the first magnet 31. It is used to drive the first magnet 31 to rotate along the axis by a predetermined angle to change the magnetic pole direction of the first magnet 31, so that the first magnet 31 and the magnetic valve core 22 generate a magnetic attraction force, driving the magnetic valve core 22 to move upward and switch to the open position.

[0078] The drive unit 32 can be an electrically driven structure such as a motor, or it can be a structure that is easy to operate manually, such as a knob or lever.

[0079] The first magnet 31 is driven by the drive unit 32 to rotate around its horizontal axis by a predetermined angle, thereby changing the orientation of the N and S poles of the first magnet 31. When the orientation of the magnetic poles of the first magnet 31 changes, the magnetic interaction between it and the magnetic valve core 22 at the bottom of the tank 20 changes, for example, from magnetic repulsion to magnetic attraction. Under the magnetic attraction force, the magnetic valve core 22 moves upward, thereby opening the water outlet 21 at the bottom of the tank 20. When the drive unit 32 drives the first magnet 31 to reset, the N and S poles of the first magnet 31 return to their initial state. At this time, the magnetic interaction between the first magnet 31 and the magnetic valve core 22 at the bottom of the tank 20 switches back to magnetic repulsion. Under the combined action of the magnetic repulsion force and the gravity of the magnetic valve core itself, the magnetic valve core 22 resets downward, thereby closing the water outlet 21 at the bottom of the tank 20.

[0080] In practical applications, when it is necessary to control the magnetic valve core 22 at the bottom of the container 20, the operator only needs to control the drive component 32 on the lid 300. The rotation of the drive component 32 drives the first magnet 31 to rotate, changing the direction of its N and S poles, thereby controlling the magnetic valve core 22 at the bottom of the container 20 through magnetic force, thus opening or closing the spout 21. This control method is intuitive, simple, convenient, and reliable.

[0081] According to the top-suction teapot provided in this embodiment, a rotatable first magnet 31 is provided inside the lid 300. A driving component 32 controls the first magnet 31 to rotate along a horizontal axis, changing its magnetic pole direction. This causes it to magnetically attract the magnetic valve core 22 on the water spout 21 at the bottom of the tea compartment, thereby driving the magnetic valve core 22 to slide vertically upwards to open the water spout 21. In this structure, since the first magnet 31 is located inside the lid 300 and uses a horizontal rotation control method, and the lid 300 is located above the tea compartment assembly 200, the magnetic force between the magnet and the magnetic valve core 22 at the bottom of the tea compartment is vertical. This allows the magnetic valve core 22 to move up and down instead of flipping, avoiding the instability of flipping control, simplifying the control structure, and improving operational reliability. Furthermore, integrating the magnet, driving component 32, and other control components into the lid 300 eliminates the need to arrange control components in the handle space, significantly reducing structural complexity and manufacturing costs, and improving product maintenance convenience. Furthermore, in the tea container assembly 200, the magnetic valve core 22 is configured to slide vertically in the spout 21, and its combination with the first magnet 31 on the lid 300 further improves the reliability and stability of opening and closing the magnetic valve core 22.

[0082] Reference Figure 10 and Figure 11 As shown, in some embodiments of this utility model, when the magnetic adsorption force is removed, the magnetic valve core 22 can be reset to the closed position under its own gravity.

[0083] In other words, the magnetic valve core 22 can slide freely in the vertical direction relative to the water outlet 21. For example, the diameter of the magnetic valve core 22 is slightly smaller than the inner diameter of the water outlet 21, so that it can slide freely up and down and can automatically return to the closed position under the action of gravity.

[0084] Based on a gravity-based reset structure, it achieves automatic reset from the open position to the closed position. The structure is simple and reliable, and the reset action is stable and responsive, ensuring the timeliness and reliability of tea and water control. No additional reset mechanism is required, reducing manufacturing costs and maintenance complexity.

[0085] Reference Figures 1 to 4 and Figures 10 to 11 As shown, in one embodiment of the present invention, the upper end of the water outlet 21 is located inside the chamber 20, and the side wall of the upper end of the water outlet 21 is provided with a water inlet hole H211.

[0086] The lower end of the water outlet 21 is fixed to the bottom wall of the chamber 20, and the lower end of the water outlet 21 has a water outlet hole H212; when the magnetic valve core 22 is in the closed position, the magnetic valve core 22 blocks the water outlet hole H212.

[0087] In other words, the upper end of the spout 21 extends into the interior of the chamber 20, while the lower end is fixedly installed on the bottom wall of the chamber 20. This structural design not only ensures a stable connection between the spout 21 and the chamber 20, but also facilitates the effective collection and dispensing of tea.

[0088] The water inlet H211 on the upper side wall of the spout 21 allows tea from the container 20 to enter the spout 21. Multiple water inlets H211 can be arranged circumferentially on the side wall of the spout 21, facilitating smooth flow of tea into the spout 21 and improving water intake efficiency. For example, the diameter of the water outlet H212 at the lower end of the spout 21 is smaller than the inner diameter of the spout 21, forming a constricted water outlet channel. When the magnetic valve core 22 is in the closed position, it reliably seals the water outlet H212.

[0089] During operation, when the magnetic valve core 22 moves upward under the magnetic attraction of the first magnet 31, the tea in the chamber 20 first flows into the spout 21 through the inlet hole H211 at the top of the spout 21, and then flows out through the open spout hole H212 into the lower pot body 100. When the first magnet 31 rotates and resets, the magnetic attraction between the first magnet 31 and the magnetic valve core 22 switches to a magnetic repulsion. Under the combined action of the magnetic repulsion and its own weight, the magnetic valve core 22 moves downward until its bottom is tightly fitted with the spout hole H212, returning to the closed state. This structural design makes the opening and closing process smoother and the sealing effect better.

[0090] Reference Figures 6 to 9 As shown, in one embodiment of this utility model, the driving component 32 includes a driving motor 321, a circuit board 322, and a battery 323. The driving motor 321 is fixed inside the cover 30, and the output shaft of the driving motor 321 is connected to the first magnet 31 to drive the first magnet 31 to rotate around the axis. Exemplarily, the driving motor 321 can be a micro motor, fixedly installed in the internal space of the cover 30. The rotation of the output shaft of the driving motor 321 drives the first magnet 31 to rotate around its horizontal axis.

[0091] A circuit board 322 is disposed inside the cover 30 and electrically connected to the drive motor 321 for controlling the drive motor 321. A battery 323 is electrically connected to the circuit board 322 for supplying power to the circuit board 322. The circuit board 322 can control the start, stop, and direction of the drive motor 321, thereby enabling the drive motor 321 to rotate the first magnet 31 by a predetermined angle, thus changing the direction of the N and S poles of the first magnet 31, thereby controlling the action of the magnetic valve core 22 at the bottom of the compartment 20. The battery 323 provides the necessary power to the circuit board 322, and a rechargeable battery 323 or a disposable battery of appropriate capacity can be selected according to actual usage requirements.

[0092] By adopting an electric drive structure, the rotation of the first magnet 31 is automatically controlled, improving the convenience and accuracy of operation. At the same time, the entire drive component 32 is integrated inside the lid 300, maintaining both structural compactness and ensuring the reliability of automatic control.

[0093] Preferably, the cover 30 is also provided with an operation button 303, which is electrically connected to the circuit board 322 for user operation to control the drive motor 321. For example, the operation button 303 can be a touch button or a mechanical button, and can be located on the top surface of the cover 30 for easy user operation. In use, the user only needs to touch or press the operation button 303 to control the opening or closing of the water outlet 21 of the chamber 20, making it simple and convenient to use.

[0094] Reference Figures 1 to 4 and Figure 6 and Figure 9 As shown, in a preferred embodiment of this invention, the magnetic poles of the first magnet 31 are arranged opposite each other in the vertical direction at a predetermined angle of 180°. That is, one magnetic pole of the first magnet 3120 faces upward and the other magnetic pole faces downward, forming a vertical magnetic field distribution. When the driving member 32 rotates the first magnet 31 180°, the positions of the upper and lower magnetic poles of the first magnet 31 are completely reversed, that is, the magnetic pole that was originally facing upward turns downward and the magnetic pole that was originally facing downward turns upward. This 180° reversal design ensures a complete switch of the magnetic force state, that is, from the strongest attractive force state to the strongest repulsive force state, or vice versa.

[0095] In actual operation, assuming the initial state is such that the N pole of the first magnet 31 faces downwards and is opposite to the N pole of the magnetic valve core 22 at the bottom of the tank 20, a repulsive force is generated between them, keeping the magnetic valve core 22 in the closed position. When it is necessary to open the water outlet 21, the drive unit 32 rotates the first magnet 31 180°, causing the N pole to face upwards and the S pole to face downwards. At this time, the S pole of the first magnet 31 is opposite to the N pole of the magnetic valve core 22, generating an attractive force. Under the action of this attractive force, the magnetic valve core 22 moves upwards, thereby opening the water outlet 21. When it is necessary to close the water outlet 21, the drive unit 32 rotates the first magnet 31 180° again to reset it, restoring the magnetic poles to the initial state. The magnetic valve core 22 returns to the closed position under the combined action of gravity and repulsive force.

[0096] This embodiment achieves the switching of the magnetic valve core 22 between opening and closing through a 180° magnetic pole reversal, and the switching action is crisp and clean. Furthermore, the vertical magnetic pole arrangement ensures that the direction of magnetic force is consistent with the direction of movement of the magnetic valve core 22, improving the force transmission efficiency and the reliability of the switching.

[0097] Reference Figures 10 to 12 As shown, in some embodiments of this utility model, the tea container assembly 200 further includes a filter element 23. The filter element 23 is disposed inside the container body 20 and fixed on the water outlet 21. An isolation cavity is defined between the filter element 23 and the bottom wall of the container body 20, and the water inlet H211 is located inside the isolation cavity. The filter element 23 adopts a mesh structure design and can be made of high-temperature resistant food-grade materials such as stainless steel filter mesh.

[0098] In this embodiment, a filter element 23 is provided, forming a closed isolation chamber between the filter element 23 and the bottom wall of the chamber 20. The function of the isolation chamber is to collect the filtered tea water and guide it to the inlet hole H211 of the spout 21. During operation, the tea water in the chamber 20 first needs to pass through the filter element 23, where larger tea leaves and tea debris are blocked at the top. After the filtered tea water enters the isolation chamber, it flows into the spout 21 through the inlet hole H211. When the magnetic valve core 22 moves upward to open the spout hole H212, the tea water can flow out from the spout 21.

[0099] The filter element 23 effectively intercepts tea leaves, preventing larger tea fragments from entering the isolation chamber. Furthermore, the isolation chamber provides a buffer space for the filtered tea, allowing for more even tea flow. Additionally, since the water inlet H211 is located within the isolation chamber, the risk of tea fragments clogging the inlet H211 is reduced, ensuring the reliability of tea flow into the water outlet 21.

[0100] In one embodiment of this utility model, the filter element 23 is a plate-shaped element or a cover-shaped element, and the filter element 23 is provided with a plurality of filter holes for filtering tea leaves.

[0101] When the filter element 23 is a plate-shaped element (such as...) Figure 10 When the filter element 23 is a cover-shaped element, the outer periphery of the plate-shaped element is close to or in contact with the peripheral wall of the chamber 20. When the filter element 23 is a cover-shaped element, the lower periphery of the cover-shaped element is close to or in contact with the bottom wall of the chamber 20.

[0102] In other words, the filter element 23 can be selected from two different structural forms: a plate-like element or a cover-like element. Both structural forms have multiple filter holes for effective filtration of tea leaves.

[0103] When a plate-shaped component is selected as the filter element 23, it has a horizontally placed circular plate structure. Multiple filter holes are evenly distributed on the plate-shaped component. The outer periphery of the plate-shaped component is close to or in direct contact with the inner peripheral wall of the chamber 20, forming a horizontal filter layer. This design ensures that all tea water must permeate downwards through the filter holes, thus achieving comprehensive filtration of the tea leaves. A mounting hole can be provided in the center of the filter element 23 for fixed connection with the water outlet 21, ensuring the stability of the filter element 23.

[0104] When a hood-shaped component is selected as the filter element 23, its overall structure is an inverted bowl shape. The top of the hood-shaped component is arc-shaped, and the lower part expands outward to form a ring-shaped lower circumference. The surface of the hood-shaped component is also provided with multiple filter holes, which can be distributed in different ways on the surface of the hood as needed. The lower circumference of the hood-shaped component is close to or in contact with the bottom wall of the chamber 20, forming a closed filtration space.

[0105] This embodiment increases the product's applicability by providing two optional filter element 23 structures. Both the plate-like and cover-like structures can form a complete filtration structure with the water outlet 21 and the isolation chamber, achieving effective separation of tea leaves.

[0106] Reference Figures 10 to 11 As shown, in one embodiment of this utility model, the peripheral wall of the chamber 20 is provided with an inwardly protruding annular retaining edge 201, and the outer peripheral edge of the plate-shaped member stops above the annular retaining edge 201. The annular retaining edge 201 forms a mating structure with the plate-shaped filter element 23, and is used to support and position the plate-shaped filter element 23.

[0107] The annular baffle 201 is integrally manufactured during the molding of the circumferential wall of the chamber body 20, and is a stepped structure that protrudes inward. The continuous circumferential arrangement of this annular baffle 201 ensures that a uniform supporting force can be formed on the plate-shaped filter element 23. This structural design allows the plate-shaped filter element 23 to be kept in a predetermined horizontal position and will not be displaced due to the weight of the tea leaves or the impact of water flow during the brewing process.

[0108] This embodiment solves the positioning and support problem of the plate-shaped filter element 23 by setting an annular baffle 201 inside the chamber 20. This structural design not only improves the reliability of the product but also ensures the stability of the filtration effect.

[0109] Reference Figures 10 to 12 As shown, in some embodiments of this utility model, the magnetic valve core 22 includes a core rod 221 and a magnet 222. The core rod 221 is slidably mounted on the water outlet 21 in the vertical direction, and the lower end of the core rod 221 is provided with a valve head 2211 for sealing the water outlet H212. The magnet 222 is disposed at the top of the core rod 221, and the magnetic poles of the magnet 222 are arranged opposite each other in the vertical direction.

[0110] In this embodiment, the magnetic valve core 22 mainly consists of a core rod 221 and a magnet 222. The core rod 221 is a slender member extending vertically, made of a metal material such as stainless steel, and can slide freely inside the water outlet 21. The lower end of the core rod 221 has a valve head 2211, the size and shape of which match the water outlet H212, enabling the sealing of the water outlet H212. Exemplarily, the valve head 2211 can have a structure with a sealing ring, or be made directly of a food-grade material with a certain degree of elasticity, to ensure a reliable seal with the water outlet H212 when in the closed position. The valve head 2211 can be designed in a conical or spherical shape, which not only facilitates sealing but also reduces water flow resistance.

[0111] A magnet 222 is mounted on the top of the core rod 221, with the N and S poles arranged vertically opposite each other. This pole arrangement determines the directionality of the magnetic force, allowing the first magnet 31 on the lid 300 to exert a precise upward magnetic attraction force on the magnetic valve core 22. For example, the magnet 222 can be made of a plated permanent magnet or an encapsulated permanent magnet to ensure safety during long-term use in tea-related environments.

[0112] The magnetic valve core 22 utilizes a structure where the core rod 221 provides guidance and support, the magnet 222 enables magnetic actuation, and the valve head 2211 ensures a tight seal. This modular structure simplifies manufacturing, facilitates maintenance and replacement, and the vertical magnetic pole arrangement ensures precise and reliable control.

[0113] Reference Figure 10 and Figure 11As shown, in one embodiment of this utility model, the valve head 2211 is a tapered structure with a diameter that gradually decreases from top to bottom. The upper end of the water outlet H212 has a tapered surface that is adapted to the tapered structure, so as to seal the water outlet H212 by contacting the tapered structure with the tapered surface.

[0114] In actual operation, when the magnetic valve core 22 descends under gravity, the conical structure of the valve head 2211 automatically guides and precisely falls into the conical surface of the outlet hole H212. This self-centering characteristic stems from the geometric features of the conical structure. Even if there is a slight eccentricity during the valve core's descent, the interaction between the conical surfaces S211 will cause the valve head 2211 to automatically return to the correct sealing position. Furthermore, the contact method between conical surfaces S211 and S211 differs from ordinary planar contact, enabling a more reliable sealing effect.

[0115] Reference Figures 10 to 12 As shown, in some embodiments of this utility model, the water outlet 21 includes a nozzle tube 211, a nut 212, and a sealing ring 213. The nozzle tube 211 is a tubular component. The bottom of the chamber 20 is provided with a mounting hole, and the nozzle tube 211 passes through the mounting hole. The outer circumferential surface of the nozzle tube 211 has a radially outwardly protruding annular shoulder 2111, which stops above the bottom wall of the chamber 20. That is, the annular shoulder 2111 serves a positioning and support function. When the nozzle tube 211 passes through the mounting hole at the bottom of the chamber 20, the annular shoulder 2111 will naturally stop above the bottom wall of the chamber 20, forming a stable support point.

[0116] Nut 212 is located below the bottom wall of the chamber 20 and is threadedly connected to the lower end of the nozzle tube 211 to fix the nozzle tube 211 to the bottom of the chamber 20. For example, the lower end of the nozzle tube 211 is machined with external threads for engaging with nut 212. Through the threaded connection between nut 212 and the lower end of nozzle tube 211, nozzle tube 211 can be firmly fixed to the bottom of the chamber 20. Sufficient tightening force is provided when nut 212 is tightened, while also facilitating disassembly and maintenance.

[0117] A sealing ring 213 is fitted onto the spout tube 211; the sealing ring 213 is located between the nut 212 and the bottom wall of the chamber 20, or the sealing ring 213 is located between the annular shoulder 2111 and the bottom wall of the chamber 20. This ensures a good seal between the spout tube 211 and the bottom of the chamber 20, allowing tea in the chamber 20 to be discharged only through the spout tube 211.

[0118] The magnetic valve core 22 is slidably mounted on the upper end of the nozzle tube 211. The water inlet H211 is located on the outer peripheral wall of the nozzle tube 211 and above the annular shoulder 2111. The water outlet H212 is located at the lower end of the nozzle tube 211. The upper end of the nozzle tube 211 serves as a sliding channel for the magnetic valve core 22. The diameter of the core rod 221 of the magnetic valve core 22 is slightly smaller than the inner diameter of the nozzle tube 211, ensuring smoother and more reliable up-and-down sliding of the magnetic valve core 22.

[0119] The modular structure of the water outlet 21, through the cooperation of the nozzle tube 211, nut 212, and sealing ring 213, achieves a detachable design, facilitating installation, maintenance, and cleaning. During actual installation, the nozzle tube 211 is inserted through the mounting hole at the bottom of the housing 20, ensuring the annular shoulder 2111 contacts the bottom wall. Then, the sealing ring 213 is installed, and finally, the nut 212 is tightened to complete the installation of the entire water outlet 21. The cooperation between the annular shoulder 2111 and the nut 212 ensures a secure connection, and the sealing ring 213 guarantees a reliable sealing effect.

[0120] Reference Figures 10 to 12 As shown, in one embodiment of this utility model, the water outlet nozzle 21 further includes a threaded plug 214. The threaded plug 214 has an external thread, and the upper end of the nozzle tube 211 has an internal thread that mates with the external thread. That is, the threaded plug 214 is threadedly connected to the upper end of the nozzle tube 211. The valve head 2211 is located below the threaded plug 214 to limit the stroke of the core rod 221, thereby preventing the magnetic valve core 22 from disengaging from the nozzle tube 211 and ensuring a stable assembly relationship between the two.

[0121] The threaded plug 214 has a vertically penetrating sliding hole, in which the core rod 221 slides. The magnet 222 is located above and blocked by the threaded plug 214. When the magnetic valve core 22 moves upward under magnetic force, the magnet 222 is blocked by the threaded plug 214, thus limiting the maximum rising height of the magnetic valve core 22. The magnet 222's location above the threaded plug 214 ensures reliable magnetic coupling between the magnet 222 and the first magnet 31 on the lid 300. This design ensures that the magnetic valve core 22 always moves within a predetermined height range, thereby guaranteeing the reliability of the magnetic valve core 22 switching between the open and closed positions.

[0122] This embodiment achieves reliable limitation and precise control of the movement stroke of the magnetic valve core 22 through the design of the threaded plug 214, thereby improving the stability and reliability of the magnetic valve core 22.

[0123] Preferably, the magnet 222 includes a housing 2221 and a second magnet 2222 disposed within the housing 2221. Exemplarily, the housing 2221 can be made of food-grade stainless steel. The fully sealed protection of the second magnet 2222 by the housing 2221 solves the safety hazards and lifespan issues that may arise from direct exposure of the magnet to tea or water. This structural design not only ensures the safety and durability of the product but also facilitates cleaning and maintenance, meeting the hygiene requirements for food contact products.

[0124] Reference Figures 6 to 9 As shown, in some embodiments of the utility model, the cover 30 includes an upper cover 301 and a lower cover 302, the lower cover 302 being connected to the upper cover 301, and a receiving cavity being defined between the upper cover 301 and the lower cover 302, the driving member 32 being fixed within the receiving cavity. Exemplarily, the upper cover 301 and the lower cover 302 are reliably connected by snaps, threads, or other detachable connection methods to form a complete cover 30.

[0125] After the upper cover 301 and the lower cover 302 are connected, they form a sealed receiving cavity. This receiving cavity can completely accommodate the drive component 32 and its related components. Inside the receiving cavity, different areas can be divided according to functional requirements, such as a motor mounting area, a circuit board 322 mounting area, and a battery 323 compartment, so that the various functional components can be rationally arranged, ensuring working space while avoiding mutual interference. The drive motor 321 can be pressed and fixed to the motor mounting area by the pressure plate 324, the circuit board 322 can be fixed to the circuit board 322 mounting area by screws, and the battery 323 can be embedded in the battery 323 compartment.

[0126] In this embodiment, the cover 30 adopts a split structure consisting of an upper cover 301 and a lower cover 302. On the one hand, this greatly simplifies the production and assembly process and improves production efficiency; on the other hand, it facilitates inspection and maintenance. When internal components need to be repaired or replaced, they can be easily operated by simply disassembling the upper cover 301 and the lower cover 302; furthermore, the design of the receiving cavity improves the waterproof performance and safety of the product, and ensures the stable operation of each functional component, thereby improving the overall performance and reliability of the product.

[0127] Preferably, the bottom of the upper cover 301 has a downwardly protruding annular portion, and the lower cover 302 is adapted to the upper cover 301 and is fitted onto the annular portion to form a closed receiving cavity. With this structure, the annular portion of the cover 30 can be easily inserted into the opening at the top of the tea container.

[0128] Reference Figures 6 to 9 As shown, in one embodiment of the present invention, the driving component 32 further includes a coupling limiter 325, which is connected between the output shaft of the driving motor 321 and the first magnet 31.

[0129] The coupling limiter 325 has a limiting protrusion 3251 on its outer periphery, and a stop portion is provided inside the cover 30. When the first magnet 31 rotates along the axis by a predetermined angle, the limiting protrusion 3251 abuts against the stop portion. The stop portion can take various forms; it can be an independent component provided inside the cover 30, or it can be the inner wall of the cover 30 or other protruding structures, as long as it can stop the limiting protrusion 3251.

[0130] The coupling limiter 325 not only transmits driving force but also has a limiting function. When the drive motor 321 drives the coupling limiter 325 and the first magnet 31 to rotate, once the predetermined rotation angle is reached, the limiting protrusion 3251 will contact the stop part, thereby preventing further rotation. This mechanical limiting method can accurately control the rotation angle of the first magnet 31, avoid excessive rotation, and ensure the reliability and accuracy of the magnetic pole direction switching during each operation.

[0131] Reference Figure 9 As shown, in one embodiment of the present invention, the first magnet 31 has an axial hole H31, and one side of the coupling limiter 325 has a plug-in portion 3252, which is plugged into the axial hole H31 and circumferentially fixed.

[0132] The other side of the coupling limiter 325 is provided with a positioning groove, and the output shaft of the drive motor 321 is provided with a drive end, which is inserted into the positioning groove and circumferentially fixed.

[0133] In this embodiment, the coupling limiter 325 is connected to the drive motor 321 and the first magnet 31 at both ends. One end is the insertion part 3252 of the coupling limiter 325, which mates with the axial hole H31 of the first magnet 31. The other end is the drive end of the output shaft of the drive motor 321, which mates with the positioning groove of the coupling limiter 325. Both ends of the connection adopt a structural design to prevent relative rotation in the circumferential direction. It can be in the form of splines, grooves, etc., as long as it can ensure circumferential fixation.

[0134] The double-ended plug structure facilitates assembly and disassembly, improving production and maintenance efficiency. The circumferentially fixed design ensures the reliability of power transmission.

[0135] Reference Figure 9As shown, in one embodiment of this utility model, the axial hole H31 has a first end and a second end, and the insertion part 3252 is inserted into the first end; a support part 304 is provided inside the cover 30, and a cylindrical part 3041 extending horizontally is provided on the support part 304. The cylindrical part 3041 passes through the second end, and the magnet is rotatable relative to the cylindrical part 3041. That is, the size of the cylindrical part 3041 matches the axial hole H31 of the first magnet 31 and passes through it.

[0136] In this structure, a revolute pair is formed between the second end of the axial hole H31 of the first magnet 31 and the cylindrical portion 3041, allowing the first magnet 31 to rotate freely relative to the fixed cylindrical portion 3041. During rotation, the first magnet 31 can rotate around the cylindrical portion 3041 as a pivot point, while the cylindrical portion 3041 also serves as a positioning support, effectively preventing the first magnet 31 from swaying during rotation and improving the stability and reliability of rotation.
