Description

Technical Field

[0001] This utility model relates to teaware, and more particularly to a top-suction tea canister sealing structure and a magnetic teapot having the same structure. Background Technology

[0002] Teapots with tea-water separation design are increasingly favored by consumers because they allow for controlled separation of tea leaves and water. This type of teapot includes a body, a tea compartment, and a lid. The tea compartment is located in the spout of the body, and the lid is placed on top of the tea compartment. A switch at the bottom of the tea compartment can be controlled to open or close. After the required brewing time, the switch is opened, allowing the tea in the tea compartment to flow into the body of the teapot.

[0003] To achieve control over the opening and closing of the switch, the inventors proposed a magnetic tea container sealing structure, including a tea container, a spout, and a magnetic valve core. The spout is located at the bottom of the tea container. The magnetic valve core includes a valve stem and a magnet at the upper end of the valve stem. The lower end of the valve stem has a sealing head. The valve stem slides through the spout. The magnet has a diameter larger than the valve stem and stops above the upper end of the spout. In practical applications, a magnetic control is installed on the lid. The user operates the magnetic control, which, through the magnetic attraction between the control and the magnet of the magnetic valve core, controls the upward movement of the valve core, thereby opening the water outlet at the bottom of the spout.

[0004] However, in actual use, this tea container sealing structure has a problem. When the magnetic valve core moves upward to open the water outlet, a certain gap is formed between the magnet and the upper end of the spout. In some cases, tea leaves in the tea container may enter this gap. When it is necessary to close the water outlet later, the magnetic valve core falls under gravity, but due to the obstruction of the tea leaves, it may not fall completely, potentially preventing the magnetic valve core from fully closing the water outlet. Therefore, this structure suffers from unstable and unreliable spout opening and closing functions, thus affecting the user experience. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this utility model is to propose a top-suction tea caddy water-sealing structure and a magnetic teapot with it.

[0006] To achieve the above objectives, on the one hand, the top-suction tea canister sealing structure according to an embodiment of the present invention includes:

[0007] Tea storage;

[0008] A water outlet is provided at the bottom of the tea container. The upper end of the water outlet is located inside the tea container and has a first central hole. The lower end of the water outlet is located outside the tea container and has a second central hole and a water outlet hole. The peripheral wall of the water outlet is provided with a water inlet hole for allowing tea water in the tea container to flow into the water outlet.

[0009] A magnetic valve core is disposed inside the water outlet. The magnetic valve core has magnetic poles arranged opposite each other in the vertical direction. The upper end of the magnetic valve core has a first positioning post, and the lower end of the magnetic valve core has a second positioning post. The first positioning post is slidably engaged with the first central hole, and the second positioning post is slidably engaged with the second central hole. The magnetic valve core can slide upward inside the water outlet and can automatically fall under the action of gravity to open or close the water outlet.

[0010] In addition, the top-suction tea canister sealing structure according to the above embodiments of this utility model may also have the following additional technical features:

[0011] According to one embodiment of the present invention, the water outlet nozzle has a valve cavity, and the magnetic valve core is disposed inside the valve cavity;

[0012] The valve chamber includes a cylindrical chamber and a conical chamber connected together. The diameter of the cylindrical chamber is larger than the outer diameter of the magnetic valve core. The conical chamber is located below the cylindrical chamber. The water outlet is located below the conical chamber and communicates with the cylindrical chamber through the conical chamber. The lower end of the magnetic valve core has a conical sealing surface that is adapted to the inner wall of the conical chamber.

[0013] When the magnetic valve core falls under its own weight, the conical sealing surface fits against the inner wall of the conical cavity, thereby blocking the connection between the cylindrical cavity and the outlet hole.

[0014] According to one embodiment of the present invention, the magnetic valve core includes a valve housing and an axial magnet encapsulated within the valve housing. The axis of the axial magnet extends in a vertical direction. The first positioning post is located at the top of the valve housing, and the second positioning post is located at the bottom of the valve housing.

[0015] According to one embodiment of the present invention, a filter cylinder is also included. The filter cylinder is located inside the tea compartment and coaxially sleeved on the upper end of the water outlet. The filter cylinder has filter holes on its circumferential surface, and the water inlet is located inside the filter cylinder.

[0016] According to one embodiment of the present invention, the valve housing includes a cylindrical shell and a cover. The top of the cylindrical shell has a receiving groove, and the axial magnet is embedded in the receiving groove. The cover is welded and sealed to the top of the cylindrical shell to seal the receiving groove. The first positioning post is located at the top of the cover, and the second positioning post is located at the bottom of the cylindrical shell.

[0017] According to one embodiment of the present invention, the water outlet includes:

[0018] The tea container has a mounting hole on its bottom wall, and the tea container passes through the mounting hole; the outer circumferential surface of the tea container has a radially outwardly protruding annular shoulder, which stops above the bottom wall of the tea container.

[0019] A nut, located below the bottom wall of the tea container and threadedly connected to the lower end of the spout, is used to fix the spout to the bottom of the tea container.

[0020] A sealing ring is fitted onto the spout; the sealing ring is located between the nut and the bottom wall of the tea container, or the sealing ring is located between the annular shoulder and the bottom wall of the tea container.

[0021] The nozzle cylinder contains a valve cavity, and the upper end of the nozzle cylinder has an opening communicating with the valve cavity. The magnetic valve core is inserted into the valve cavity through the opening, and the opening is sealed by a plug. The first central hole is located on the plug, and the water outlet and the second central hole are located at the bottom of the nozzle cylinder.

[0022] According to one embodiment of the present invention, the plug has an external thread, and the opening has an internal thread that mates with the external thread.

[0023] According to one embodiment of the present invention, the upper end of the plug has an annular retaining edge protruding radially outward, the annular retaining edge is provided with a first groove, the annular shoulder is provided with a second groove, the filter cylinder is sandwiched between the annular shoulder and the annular retaining edge, and the upper end of the filter cylinder is engaged in the first groove, and the lower end of the filter cylinder is engaged in the second groove.

[0024] According to one embodiment of the present invention, the first central hole is a blind hole and is located on the bottom surface of the plug.

[0025] On the other hand, the magnetic teapot according to an embodiment of the present invention includes:

[0026] The top-suction tea canister water-sealing structure described above;

[0027] A magnetic control device is located above the water sealing structure of the tea chamber and can move under the operation of the user to form a magnetic attraction between the magnetic control device and the magnetic valve core, and the magnetic attraction drives the magnetic valve core to move upward to open the water outlet.

[0028] According to the top-suction tea hopper sealing structure and magnetic teapot with it provided in this embodiment of the utility model, the magnetic valve core is built into the spout. The upper end of the magnetic valve core has a first positioning post, and the lower end has a second positioning post. The upper end of the spout has a first central hole that slides with the first positioning post, and the lower end has a second central hole that slides with the second positioning post. Thus, in practical applications, the magnetic attraction generated by the magnetic control on the lid causes the magnetic valve core to slide upwards to open the spout, and then automatically falls down to close the spout under gravity. Since the magnetic valve core is completely inside the spout, interference from tea leaves is prevented. Simultaneously, the sliding cooperation between the first positioning post and the first central hole, and between the second positioning post and the second central hole, ensures stable and reliable up-and-down sliding of the magnetic valve core within the spout. Therefore, the stability and reliability of opening and closing the spout can be significantly improved, enhancing the user experience and overall product performance.

[0067] The following describes in detail, with reference to the accompanying drawings, the top-suction tea hopper 10 water-sealing structure and the magnetic teapot having it as embodiments of the present invention.

[0068] Reference Figures 1 to 5 As shown, the top-suction tea chamber 10 water sealing structure provided according to the embodiment of this utility model includes a tea chamber 10, a water outlet 20, and a magnetic valve core 30.

[0069] Specifically, the tea container 10 is used to hold tea leaves and warm water for steeping. The tea container 10 can be made of high-temperature resistant food-grade materials, such as glass, ceramic, or stainless steel.

[0070] A spout 20 is located at the bottom of the tea container 10 and is used to discharge tea water from the tea container 10. The upper end of the spout 20 is located inside the tea container 10 and has a first central hole H203. The lower end of the spout 20 is located outside the tea container 10 and has a second central hole H204 and a water outlet H202. The peripheral wall of the spout 20 has a water inlet H201 for allowing tea water from the tea container 10 to flow into the spout 20. Tea water in the tea container 10 can flow into the spout 20 through the water inlet H201 and then flow out from the water outlet H202 at the lower end of the spout 20. The spout 20 and the bottom of the tea container 10 can be sealed together, or the spout 20 and the bottom of the tea container 10 can be integrated into a single design to ensure that tea water flows out from the spout 20 during use.

[0071] A magnetic valve core 30 is disposed within the spout 20. The magnetic valve core 30 has magnetic poles arranged opposite each other in the vertical direction. These opposing magnetic poles can form a stable magnetic coupling with the magnetic control 50 on the lid, facilitating the actuation of the magnetic valve core 30 using the magnetic control 50. Furthermore, since the magnetic valve core 30 is located inside the spout 20, which only allows tea to flow in, the magnetic valve core 30 moves entirely within the spout 20 during use, unaffected by tea leaves. This ensures the stability and reliability of the magnetic valve core 30's opening and closing action on the spout H202.

[0072] The upper end of the magnetic valve core 30 has a first positioning post 3031, and the lower end of the magnetic valve core 30 has a second positioning post 3011. The first positioning post 3031 is slidably engaged with the first central hole H203, and the second positioning post 3011 is slidably engaged with the second central hole H204. The magnetic valve core 30 can slide upward within the water outlet 20 and can automatically fall under the action of gravity to open or close the water outlet H202.

[0073] The sliding fit between the first positioning post 3031 and the first central hole H203, and the second positioning post 3011 and the second central hole H204, ensures that the magnetic valve core 30 has a good guiding and positioning function during its vertical movement within the water outlet 20, thereby ensuring that the vertical movement of the valve core is stable and reliable.

[0074] In practical applications, the tea container 10 can be assembled into the spout of the teapot. A lid can be installed on the top of the tea container 10, and a magnetic control 50 is mounted on the lid. This magnetic control 50 also has magnetic properties and forms a magnetic coupling relationship with the magnetic valve core 30. Furthermore, the magnetic force between the magnetic control 50 and the magnetic valve core 30 can be changed by operating the magnetic control 50, for example, by rotating the magnetic control 50 to change its magnetic pole direction. When a magnetic attraction occurs between the magnetic control 50 and the magnetic valve core 30, the magnetic valve core 30 slides upward, opening the water outlet H202 and allowing tea to flow out. After the tea is discharged, the magnetic control 50 can be reset, changing the magnetic attraction between the magnetic control 50 and the magnetic valve core 30 to a magnetic repulsion. At this time, the magnetic valve core 30 automatically falls back down under gravity, resealing and closing the water outlet H202. In this way, the opening and closing of the water outlet H202 can be controlled.

[0075] According to the top-suction tea container 10 water-sealing structure provided in this embodiment of the utility model, the magnetic valve core 30 is built into the water outlet 20, and the upper end of the magnetic valve core 30 is provided with a first positioning post 3031, and the lower end of the magnetic valve core 30 is provided with a second positioning post 3011. The upper end of the water outlet 20 is provided with a first central hole H203 that slides and cooperates with the first positioning post 3031, and the lower end of the water outlet 20 is provided with a second central hole H204 that slides and cooperates with the second positioning post 3011. Thus, in specific applications, the magnetic attraction generated by the magnetic control 50 on the lid on the magnetic valve core 30 causes the magnetic valve core 30 to slide upward to open the water outlet H202, and automatically fall down to close the water outlet H202 under the action of gravity. Since the magnetic valve core 30 is completely inside the water outlet 20, it prevents tea leaves from interfering with the magnetic valve core 30. At the same time, the sliding fit between the first positioning post 3031 and the first central hole H203, and the second positioning post 3011 and the second central hole, ensures that the magnetic valve core 30 slides up and down stably and reliably within the water outlet 20. As a result, the stability and reliability of opening and closing the water outlet H202 can be significantly improved, enhancing the user experience and the overall performance of the product.

[0076] Reference Figure 3 As shown, in some embodiments of this utility model, the water outlet 20 has a valve cavity, and the magnetic valve core 30 is disposed in the valve cavity.

[0077] The valve cavity includes a cylindrical cavity P201 and a conical cavity P202 connected together. The diameter of the cylindrical cavity P201 is larger than the outer diameter of the magnetic valve core 30. Thus, when the magnetic valve core 30 is installed in the valve cavity, an annular gap cavity is formed between the outer circumferential surface of the magnetic valve core 30 and the inner circumferential surface of the cylindrical cavity P201. The tea water in the tea container 10 enters the annular gap cavity through the water inlet hole H201 on the peripheral wall of the water outlet 20.

[0078] The conical cavity P202 is located below the cylindrical cavity P201, and the water outlet H202 is located below the conical cavity P202 and communicates with the cylindrical cavity P201 through the conical cavity P202. In other words, the cylindrical cavity P201, the conical cavity P202, and the water outlet H202 are connected sequentially from top to bottom, and the tea in the cylindrical cavity P201 must pass through the conical cavity P202 to flow out through the water outlet H202.

[0079] The lower end of the magnetic valve core 30 has a conical sealing surface S30 that is adapted to the inner wall of the conical cavity P202. When the magnetic valve core 30 falls under its own weight, the conical sealing surface S30 fits against the inner wall of the conical cavity P202 to block the communication between the cylindrical cavity P201 and the outlet hole H202.

[0080] In practical applications, in the initial state, there is a magnetic repulsion between the magnetic control unit 50 and the magnetic valve core 30. At this time, the magnetic valve core 30 remains in a falling and blocking state under its own gravity and magnetic repulsion. In this blocking state, the conical sealing surface S30 at the lower end of the magnetic valve core 30 is in contact with the inner wall of the conical cavity P202, thereby sealing the conical cavity P202 and blocking the connection between the water outlet H202 and the cylindrical cavity P201. At this time, the water outlet H202 is closed, and the tea in the cylindrical cavity P201 cannot flow into the water outlet H202. When it is necessary to open the water outlet H202, the magnetic control 50 can be operated to switch the magnetic repulsion between the magnetic control 50 and the magnetic valve core 30 to a magnetic attraction. Under the action of the magnetic attraction, the magnetic valve core 30 moves upward, thereby separating the conical sealing surface S30 at the lower end of the magnetic valve core 30 from the inner wall of the conical cavity P202. The conical cavity P202 is opened, and the tea in the cylindrical cavity P201 can flow into the water outlet H202 through the conical cavity P202 and then flow out from the water outlet H202, thus realizing the discharge of tea.

[0081] In this embodiment, the conical cavity P202 utilizes its conical structure to achieve automatic sealing and closure. When the user drives the magnetic valve core 30 to slide upward using the magnetic control 50, the conical sealing surface S30 separates from the inner wall of the conical cavity P202, allowing water to flow between the water outlet H202 and the cylindrical cavity P201. When the magnetic valve core 30 naturally falls under gravity, the sealing action of the conical sealing surface S30 quickly restores the sealing state, preventing accidental leakage of tea. This structural design allows for automatic centering during gravity-induced descent, achieving better adhesion and improving the reliability of automatic sealing.

[0082] Reference Figures 1 to 3 As shown, in one embodiment of this utility model, the magnetic valve core 30 includes a valve housing and an axial magnet 302 encapsulated in the valve housing. The valve housing can be made of food-grade stainless steel. On the one hand, stainless steel has the characteristics of high strength, corrosion resistance, and meeting food-grade hygiene requirements. On the other hand, stainless steel has a large mass and can make good use of its own gravity to achieve the function of falling and sealing water.

[0083] The axis of the axial magnet 302 extends in the vertical direction. The axial magnet 302 refers to a magnet with two magnetic poles arranged opposite each other in the axial direction. This axial magnet 302 can better cooperate with the external magnetic control 50. For example, the magnetic control 50 can also use magnetic poles arranged opposite each other in the vertical direction. In this way, by rotating the magnetic control 50 to change the direction of the magnetic poles, the magnetic force between the magnetic control 50 and the axial magnet 302 can be changed. For example, rotating the magnetic control 50 by 180° will swap the N pole and the S pole, thereby switching the magnetic force between the magnetic control 50 and the axial magnet 302 between repulsive and attractive forces.

[0084] The first positioning post 3031 is located at the top of the valve housing, and the second positioning post 3011 is located at the bottom of the valve housing. This facilitates sliding engagement with the first central hole H203 at the upper end of the water outlet 20 and the second central hole H204 at the lower end of the water outlet 20, respectively, ensuring that the magnetic valve core 30 slides smoothly and stably within the water outlet 20.

[0085] In this embodiment, by encapsulating the axial magnet 302 inside the valve housing, it is ensured that the axial magnet 302 will not come into contact with the tea, thus improving hygiene and safety. Furthermore, it also improves the reliability of the movement of the magnetic valve core 30 within the spout 20, thereby enhancing the reliability and stability of the spout 20's on / off control.

[0086] Reference Figures 1 to 5 As shown, in some embodiments of this utility model, the top-suction tea chamber 10 water sealing structure further includes a filter cylinder 40. The filter cylinder 40 is located inside the tea chamber 10 and coaxially sleeved on the upper end of the water outlet 20. The circumferential surface of the filter cylinder 40 is provided with filter holes H40, and the water inlet hole H201 is located inside the filter cylinder 40.

[0087] In this embodiment, the filter cylinder 40, which is sleeved on the outer side of the water outlet 20, has filter holes H40 located on the outer side of the filter cylinder 40 relative to the cover structure covering the water outlet 20. The filter cylinder 40 has a certain height at the bottom of the tea container 10, making it difficult for tea leaves to completely cover it. As a result, the filter holes H40 are not completely covered, and at least some of the filter holes H40 remain unobstructed. Therefore, the smooth flow of tea water can be improved.

[0088] Reference Figure 3 As shown, in one embodiment of the present invention, the valve housing includes a cylindrical shell 301 and a cover 303. The top of the cylindrical shell 301 has a receiving groove, and the axial magnet 302 is embedded in the receiving groove. The cover 303 is welded and sealed to the top of the cylindrical shell 301 to seal the receiving groove. The first positioning post 3031 is located at the top of the cover 303, and the second positioning post 3011 is located at the bottom of the cylindrical shell 301.

[0089] In this embodiment, the valve housing, consisting of a cylindrical shell 301 and a welded and sealed cap 303, can achieve a sealed encapsulation of the axial magnet 302. Its structure is simple and the sealing is reliable and stable.

[0090] Reference Figures 1 to 3As shown, in one embodiment of this utility model, the spout 20 includes a spout cylinder 201, a nut 202, and a sealing ring 203. The bottom wall of the tea container 10 is provided with a mounting hole, and the spout cylinder 201 passes through the mounting hole. The outer peripheral surface of the spout cylinder 201 has a radially outwardly protruding annular shoulder 2011, which stops above the bottom wall of the tea container 10 to ensure that the spout cylinder 201 is held on the tea container 10.

[0091] Nut 202 is located below the bottom wall of the tea container 10 and is threadedly connected to the lower end of the spout 201 to fix the spout 201 to the bottom of the tea container 10. Sealing ring 203 is fitted onto the spout 201; the sealing ring 203 is located between the nut 202 and the bottom wall of the tea container 10, or the sealing ring 203 is located between the annular shoulder 2011 and the bottom wall of the tea container 10.

[0092] The nozzle cylinder 201 has the valve cavity formed inside, and the upper end of the nozzle cylinder 201 has an opening communicating with the valve cavity. The magnetic valve core 30 is inserted into the valve cavity through the opening, and the opening is sealed by the plug 204. The first central hole H203 is located on the plug 204, and the water outlet hole H202 and the second central hole H204 are located at the bottom of the nozzle cylinder 201.

[0093] During assembly, the magnetic valve core 30 is first inserted into the nozzle cylinder 201 through the opening at the upper end of the nozzle cylinder 201, and the second positioning pin 3011 at the lower end of the magnetic valve core 30 is inserted into the second central hole H204 at the lower end of the nozzle cylinder 201. Then, the plug 204 is sealed in the opening of the water outlet nozzle 20, and the first positioning pin 3031 is inserted into the first central hole H203 on the plug 204, thus completing the installation between the magnetic valve core 30 and the water outlet nozzle 20.

[0094] After the magnetic valve core 30 is installed into the spout cylinder 201, the spout cylinder 201 is inserted from top to bottom into the mounting hole at the bottom of the tea chamber 10, so that the annular shoulder 2011 on the outer circumference of the spout cylinder 201 is evenly pressed against the bottom wall of the tea chamber 10, thereby fixing the longitudinal position of the spout cylinder 201. Next, the sealing gasket is fitted onto the lower end of the spout cylinder 201 from below the bottom wall of the tea chamber 10, and then the nut 202 is connected to the external thread at the lower end of the spout cylinder 201. By tightening the nut 202, the spout cylinder 201 is firmly fixed to the tea chamber 10, ensuring that the sealing ring 203 is firmly pressed against the bottom wall of the tea chamber 10, thereby achieving a sealed connection between the tea chamber 10 and the spout 20, and completing the assembly between the spout 20 and the tea chamber 10.

[0095] The water outlet nozzle 20 employs a modular structure, utilizing the nozzle tube, nut 202, sealing ring 203, and plug 204 to achieve a detachable design, facilitating installation, maintenance, and cleaning. It also facilitates the assembly of the magnetic valve core 30 with the water outlet nozzle 20.

[0096] Preferably, the plug 204 has an external thread, and the opening has an internal thread that mates with the external thread. In this way, the plug 204 is threadedly connected to the upper end of the nozzle 201, making assembly and disassembly simple and convenient.

[0097] Reference Figure 3 As shown, in one embodiment of the present invention, the upper end of the plug 204 has an annular retaining edge 2041 that protrudes radially outward. The annular retaining edge 2041 is provided with a first groove, and the annular shoulder 2011 is provided with a second groove. The filter cylinder 40 is sandwiched between the annular shoulder 2011 and the annular retaining edge 2041, and the upper end of the filter cylinder 40 is engaged in the first groove, and the lower end of the filter cylinder 40 is engaged in the second groove.

[0098] During assembly, after the magnetic valve core 30 is installed into the nozzle cylinder 201, the filter cylinder 40 is first fitted onto the outside of the nozzle cylinder 201, ensuring that the lower end of the filter cylinder 40 is engaged with the second slot on the annular shoulder 2011. Then, the plug 204 is screwed into the opening at the upper end of the nozzle cylinder 201. Finally, when the plug 204 is fully tightened, the upper end of the filter cylinder 40 is engaged with the first slot on the annular retaining edge 2041. In this way, the rapid assembly of the filter cylinder 40, the magnetic valve core 30, and the nozzle cylinder 201 is achieved. This structure ensures that the filter cylinder 40 is easy and convenient to install, and that the filter cylinder 40 and the water outlet nozzle 20 are reliably assembled.

[0099] Preferably, the first central hole H203 is a blind hole and is located on the bottom surface of the plug 204. In this way, the tea leaves in the tea compartment 10 will not enter the first central hole H203, and will not interfere with the movement of the magnetic valve core 30 in the water outlet 20, thereby improving the reliability of the movement of the magnetic valve core 30.

[0100] This utility model embodiment also provides a magnetic teapot, including a top-suction tea chamber 10 water-sealing structure and a magnetic control unit 50 as described in the above embodiment.

[0101] The magnetic control 50 is located above the water sealing structure of the tea chamber 10 and can move under the operation of the user so that a magnetic attraction is formed between the magnetic control 50 and the magnetic valve core 30, and the magnetic force drives the magnetic valve core 30 to move upward to open the water outlet 20.

[0102] Understandably, the magnetic teapot also includes a body and a lid. The tea compartment 10 is located in the spout of the body, and the lid is placed on top of the tea compartment 10. The magnetic control 50 can be mounted on the lid. Preferably, the magnetic poles of the magnetic control 50 and the magnetic valve core 30 are arranged opposite each other in the vertical direction.

[0103] In use, the user operates the magnetic control 50 (e.g., rotates the magnetic control 50) to change the magnetic force between the magnetic control 50 and the magnetic valve core 30, creating a magnetic attraction between them. Under this force, the magnetic valve core 30 slides upwards, thus opening the water outlet H202 at the bottom of the water outlet 20. When it is necessary to close the water outlet H202, the magnetic control 50 is rotated 180°, reversing the N and S poles. This switches the force between the magnetic control 50 and the magnetic valve core 30 to a repulsive force. The magnetic valve core 30 then quickly returns to its original position under the combined effect of its own weight and the repulsive force, closing the water outlet H202.

[0104] According to the magnetic teapot provided in this embodiment, the magnetic valve core 30 is built into the spout 20. The upper end of the magnetic valve core 30 is provided with a first positioning post 3031, and the lower end of the magnetic valve core 30 is provided with a second positioning post 3011. The upper end of the spout 20 is provided with a first central hole H203 that slides with the first positioning post 3031, and the lower end of the spout 20 is provided with a second central hole H204 that slides with the second positioning post 3011. Thus, in practical applications, the magnetic attraction generated by the magnetic control 50 on the lid on the magnetic valve core 30 causes the magnetic valve core 30 to slide upwards to open the spout H202, and then automatically falls down to close the spout H202 under gravity. Since the magnetic valve core 30 is completely inside the water outlet 20, it prevents tea leaves from interfering with the magnetic valve core 30. At the same time, the sliding fit between the first positioning post 3031 and the first central hole H203, and the second positioning post 3011 and the second central hole, ensures that the magnetic valve core 30 slides up and down stably and reliably within the water outlet 20. As a result, the stability and reliability of opening and closing the water outlet H202 can be significantly improved, enhancing the user experience and the overall performance of the product.
