[0071] The utility model embodiment hand top suction type tea kettle is described in detail below with reference to the drawings.

[0072] Referring to Figs. 1 to 4 As shown in the figure, the hand top suction type tea kettle provided by the utility model embodiment comprises a kettle body 10, a tea bin 20 and a kettle cover 30.

[0073] Specifically, the kettle body 10 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 10 for pouring out the tea water.

[0074] The tea bin 20 is used for containing tea leaves and brewing tea water. The tea bin 20 is arranged in the kettle opening of the kettle body 10. The tea bin 20 is made of high-temperature-resistant food-grade materials such as glass, ceramic, stainless steel, etc. The tea bin 20 has a proper capacity space, and the top of the tea bin 20 is provided with an opening for conveniently adding tea leaves.

[0075] The bottom of the tea bin 20 is provided with a water outlet 21 for discharging liquid in the tea bin 20. The water outlet 21 and the bottom of the tea bin 20 can be sealingly connected, or the water outlet 21 and the bottom of the tea bin 20 are designed in an integrated manner to ensure that tea water flows out of the water outlet 21 into the kettle body 10 during use.

[0076] The water outlet 21 is provided with a magnetic valve core 22 capable of moving up and down. When the magnetic valve core 22 moves upward, the magnetic valve core 22 can open the water outlet 21. After the tea water in the tea bin 20 is brewed for a required time, the water outlet 21 is controlled to be opened, so that the tea water flows into the kettle body 10 below and is then poured out from the kettle body 10 for drinking.

[0077] The kettle cover 30 includes a cover body 301 and a radial magnet 302. The cover body 301 is arranged on the top of the tea bin 20 and is made of glass, ceramic, metal, wood or the like. The cover body 301 has a disc-shaped structure and is sized to fit the opening on the top of the tea bin 20.

[0078] The top surface of the cover body 301 is provided with a mounting groove H301 for mounting the radial magnet 302. The radial magnet 302 is arranged in the mounting groove H301 and can be rotated by a user along its own axis by a predetermined angle. The axis of the radial magnet 302 extends in the horizontal direction. That is, the user can directly manually operate the radial magnet 302 in the mounting groove H301 to rotate the radial magnet 302 around its own axis.

[0079] The radial magnet 302 has opposite magnetic poles in the radial direction. When the radial magnet 302 is rotated by a predetermined angle, a magnetic attraction force is generated between the radial magnet 302 and the magnetic valve core 22, which drives the magnetic valve core 22 to move upward and open the water outlet 21.

[0080] When the user rotates the radial magnet 302 around its own axis by a predetermined angle, the directions of the N and S poles of the radial magnet 302 are changed, and the magnetic interaction between the radial magnet 302 and the magnetic valve core 22 at the bottom of the tea bin 20 is changed, for example, from magnetic repulsion to magnetic attraction, so that the magnetic valve core 22 moves upward under the magnetic attraction force, thereby opening the water outlet 21 at the bottom of the tea bin 20.

[0081] The manual top suction type tea kettle provided by the embodiment of the present application effectively converts the rotation operation of the user into the up-down movement of the magnetic valve core 22 by arranging the radial magnet 302 that can rotate around its own axis in the cover 301 and using the magnetic attraction force between the radial magnet 302 and the magnetic valve core 22 at the bottom of the tea bin 20, thereby realizing the precise control of the opening and closing of the water outlet 21. In this structure, the magnetic valve core 22 slides up and down in the water outlet 21 in the vertical direction, and the combination of the magnetic valve core 22 and the radial magnet 302 on the cover 301 significantly improves the reliability and stability of the opening and closing of the magnetic valve core 22. At the same time, the radial magnet 302 is arranged in the cover 301, which discards the scheme of arranging the control assembly in the handle space, greatly reduces the structural complexity and manufacturing cost, and improves the maintenance convenience of the product. In addition, the radial magnet 302 is arranged in the mounting groove H301 on the cover 301, which facilitates the operation control of the user during use.

[0082] Preferably, when the radial magnet 302 is reset, the magnetic attraction force between the radial magnet 302 and the magnetic valve core 22 is converted into magnetic repulsion force, and the magnetic valve core 22 can be reset and fall down under the magnetic repulsion force and its own gravity to close the water outlet 21. In specific use, the user can operate the reverse rotation of the radial magnet 302 to reset it, and the N and S poles of the radial magnet 302 return to the initial state, at which time the magnetic interaction between the radial magnet 302 and the magnetic valve core 22 at the bottom of the tea bin 20 is switched to magnetic repulsion force again, and the magnetic valve core 22 is reset downward under the dual action of the magnetic repulsion force and the gravity of the magnetic core valve core, thereby closing the water outlet 21 at the bottom of the tea bin 20.

[0083] Based on the dual reset action of the magnetic repulsion force and the gravity, the magnetic core valve core is quickly and automatically reset, the structure is simple and reliable, the reset action is stable and the response is rapid, and the timeliness and reliability of the tea water control are ensured. Without additional reset mechanism, the manufacturing cost and maintenance difficulty are reduced.

[0084] Exemplarily, the diameter of the magnetic valve core 22 is slightly smaller than the inner diameter of the water outlet 21, so that it can freely slide up and down and automatically fall down under the action of gravity.

[0085] In some embodiments of the present application, the predetermined angle is 180°, and the magnetic poles of the radial magnet 302 are arranged oppositely in the vertical direction. That is, one magnetic pole of the radial magnet 302 faces upward, and the other magnetic pole faces downward, forming a vertical magnetic field line distribution. When the user rotates the radial magnet 302 by 180°, the positions of the upper and lower magnetic poles of the radial magnet 302 are completely reversed, that is, the originally upward magnetic pole is turned downward, and the originally downward magnetic pole is turned upward. This 180° reversal design ensures complete switching of the magnetic force action state, that is, from the strongest attractive force state to the strongest repulsive force state, or vice versa.

[0086] In actual operation, assuming that in the initial state, the S pole of the radial magnet 302 faces downward and is opposite to the S pole of the magnetic valve core 22 at the bottom of the tea bin 20, at this time, repulsive force is generated between the two, causing the magnetic valve core 22 to remain in the closed position. When it is necessary to open the water outlet spout 21, the radial magnet 302 is rotated by 180°, causing the S pole to turn upward and the N pole to turn downward. At this time, the N pole of the radial magnet 302 is opposite to the S pole of the magnetic valve core 22, generating an attractive force that causes the magnetic valve core 22 to move upward, thereby opening the water outlet spout 21. When it is necessary to close the water outlet spout 21, the radial magnet 302 is reversely rotated by 180° to reset, causing the magnetic poles to return to the initial state, and the magnetic valve core 22 falls downward under the combined action of gravity and repulsive force to close the water outlet spout 21.

[0087] This embodiment realizes switching of the opening or closing of the magnetic valve core 22 through 180° magnetic pole reversal, and the switching action is crisp and neat. Moreover, the vertical arrangement of the magnetic poles ensures that the direction of the magnetic force is consistent with the movement direction of the magnetic valve core 22, improving the force transmission efficiency and the reliability of the switching.

[0088] In an embodiment of the present application, the water outlet spout 21 is sealingly fixed to the bottom wall of the tea bin 20, the upper end of the water outlet spout 21 is located inside the tea bin 20, and the upper end of the water outlet spout 21 is provided with a water inlet hole H201; the lower end of the water outlet spout 21 is located outside the tea bin 20, and the lower end of the water outlet spout 21 has a water outlet hole H202 that is in communication with the water inlet hole H201.

[0089] This structure can ensure that the tea water in the tea bin 20 can enter the water outlet spout 21 through the water inlet hole H201 and then flow out of the water outlet hole H202 of the water outlet spout 21 into the kettle body 10, realizing the introduction of the tea water in the tea bin 20 into the kettle body 10. Preferably, the water inlet hole H201 is a plurality of water inlet holes H201, and the plurality of water inlet holes H201 are circumferentially distributed on the side wall of the water outlet spout 21, facilitating the full and smooth flow of the tea water into the water outlet spout 21 and improving the water inlet efficiency.

[0090] The magnetic valve core 22 can slide in the 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 blocks the water outlet hole H202, and when the magnetic valve core 22 is in the open position, the magnetic valve core 22 opens the water outlet hole H202. Exemplarily, the diameter of the water outlet hole H202 at the lower end of the water outlet nozzle 21 is smaller than the inner diameter of the water outlet nozzle 21, forming a constricted water outlet channel. When the magnetic valve core 22 is in the closed position, the magnetic valve core 22 can reliably block the water outlet hole H202.

[0091] In use, when the magnetic valve core 22 moves upward to the open position under the magnetic attraction force of the radial magnet 302, the tea water in the tea bin 20 first flows into the water outlet nozzle 21 through the water inlet hole H201 at the upper end of the water outlet nozzle 21, and then flows out from the opened water outlet hole H202 to the inside of the lower kettle body 10. When the radial magnet 302 rotates and resets, the magnetic attraction force between the radial magnet 302 and the magnetic valve core 22 is switched to a magnetic repulsion force, and the magnetic valve core 22 moves downward to the closed position under the dual action of the magnetic repulsion force and the weight, until the bottom of the magnetic valve core 22 tightly abuts against the water outlet hole H202, and the closed state is restored. This structure design makes the switching process more smooth and the sealing effect better.

[0092] In an embodiment of the utility model, the kettle cover 30 further comprises a support 304, the support 304 has two opposite elastic arms 3041, and each elastic arm 3041 is provided with a rotating shaft part 3042. The support 304 can adopt plastic material or metal material with certain elasticity, and it is only necessary to ensure that the two elastic arms 3041 have certain elasticity. The two elastic arms 3041 can be sheet-shaped members extending downward, and the rotating shaft part 3042 is a cylindrical structure protruding inward from the inner side of the elastic arm 3041.

[0093] The radial magnet 302 is located between the two elastic arms 3041, the rotating shaft part 3042 of one of the two elastic arms 3041 is pivotally connected with one end of the shaft hole H302, and the rotating shaft part 3042 of the other of the two elastic arms 3041 is pivotally connected with the other end of the shaft hole H302. That is, the two rotating shaft parts 3042 on the support 304 are pivotally connected with the shaft holes H302 at the two ends of the radial magnet 302, so that the radial magnet 302 is installed on the support 304, and the radial magnet 302 can rotate around its own axis, and the magnetic pole can be accurately reversed under the direct operation of the user, thereby effectively controlling the magnetic valve core 22.

[0094] The bracket 304 is detachably arranged in the mounting groove H301, and at least part of the radial magnet 302 is exposed outside the bracket 304 for user operation. The bracket 304 is detachably arranged in the mounting groove H301 of the cover body 301 to ensure the firmness of the overall structure. At least part of the radial magnet 302 is exposed outside the bracket 304, so that the user can easily and conveniently manually operate the radial magnet 302.

[0095] The embodiment adopts the structure of the bracket 304 and the double elastic arms 3041, and realizes the pivoting cooperation of the shaft hole H302 arranged on the radial magnet 302 and the rotating shaft part 3042 on the elastic arm 3041, thereby ensuring the accuracy and stability of the rotating operation of the radial magnet 302. The detachable design of the bracket 304 facilitates the assembly of components and the later maintenance. The partial exposure of the radial magnet 302 facilitates the direct operation of the user, improves the reliability of the operation of the radial magnet 302, and further ensures the response speed and reliability of the opening and closing of the magnetic valve core 22, thereby effectively realizing the accurate control of the tea water outflow and closure. In addition, the overall structure is simple, and the production cost is low.

[0096] In an embodiment of the utility model, the radial magnet 302 is sleeved with an anti-skid sleeve 303 to increase the friction force when the user operates and contacts. The anti-skid sleeve 303 can be fixed in a way of covering and tightening, adhering, buckling, etc. The anti-skid sleeve 303 is made of a material with high friction coefficient, such as rubber or silicone, and its surface is processed by fine texture or concave-convex design, which can significantly increase the friction force between the user's hand and the magnet sleeve during operation.

[0097] When the user operates the radial magnet 302, the anti-skid surface formed by the anti-skid sleeve 303 effectively prevents finger sliding, thereby improving the reliability of the rotating operation. The anti-skid sleeve 303 is sleeved on the radial magnet 302, and also takes into account the aesthetics and durability, so that the radial magnet 302 is not easy to be damaged.

[0098] In the embodiment, the setting of the anti-skid sleeve 303 significantly improves the holding stability and friction force of the user when operating the radial magnet 302, effectively prevents the hand sliding phenomenon in the rotating operation, thereby ensuring the accuracy of the magnetic pole conversion and the fast response of the magnetic valve core 22, and improving the overall reliability and use experience of the product.

[0099] In one embodiment of the utility model, two ends of radial magnet 302 are respectively provided with end cover 305, one of two end cover 305 is provided with limiting portion 3052, limiting portion 3052 is limited with support 304 or cover body 301 cooperation, to limit the predetermined angle. Preferably, end cover 305 has central shaft 3051, the central shaft 3051 of two end cover 305 is inserted into the both ends of radial magnet 302 shaft hole H302, realizes the stable and reliable assembly connection between end cover 305 and radial magnet 302.

[0100] The structure is through setting end cover 305 at the both ends of radial magnet 302, and setting limiting portion 3052 on one of end cover 305, and forms cooperation with support 304 or cover body 301, effectively limits the rotation angle of radial magnet 302, for example, guarantees that radial magnet 302 rotates within 180 °, and further ensures that the magnetic pole direction of radial magnet 302 can be reliably switched, so that the opening and closing control of magnetic valve core 22 is more stable and reliable.

[0101] In some embodiments of the utility model, filter piece 23 is further provided in tea bin 20, filter piece 23 is fixed on water outlet nozzle 21, and an isolation cavity is defined between filter piece 23 and the bottom wall of tea bin 20, and water inlet hole H201 is located in the isolation cavity. Filter piece 23 adopts a mesh structure design and can be made of stainless steel filter screen and other high-temperature-resistant food-grade materials.

[0102] In the embodiment, filter piece 23 is provided, and a closed isolation cavity is formed between filter piece 23 and the bottom wall of tea bin 20. The isolation cavity functions to collect filtered tea water and guide it to water inlet hole H201 of water outlet nozzle 21. In use, the tea water in tea bin 20 first needs to pass through filter piece 23, and larger tea leaves and tea leaf debris are blocked above filter piece 23. The filtered tea water enters the isolation cavity and then flows into water outlet nozzle 21 through water inlet hole H201 on water outlet nozzle 21. When magnetic valve core 22 moves upward to open water outlet hole H202, the tea water can flow out of water outlet nozzle 21.

[0103] Through the filtration of filter piece 23, tea leaves can be effectively intercepted to prevent larger tea leaf debris from entering the isolation cavity. Moreover, the isolation cavity provides a buffer space for the filtered tea water, making the tea water flow more uniformly. In addition, since water inlet hole H201 is located in the isolation cavity, the risk of tea leaf debris blocking water inlet hole H201 is reduced, ensuring the reliability of the tea water flowing into water outlet nozzle 21.

[0104] In one embodiment of the utility model, filter piece 23 is a plate-shaped piece or a cover-shaped piece, and a plurality of filter holes for filtering tea leaves are provided on filter piece 23.

[0105] When the filter 23 is a plate-shaped member, the outer periphery of the plate-shaped member is close to or in contact with the peripheral wall of the tea bin 20. When the filter 23 is a cover-shaped member, the lower periphery of the cover-shaped member is close to or in contact with the bottom wall of the tea bin 20.

[0106] That is, the filter 23 can be selected from two different structural forms: a plate-shaped member or a cover-shaped member. Both of the two structural forms are provided with a plurality of filter holes for effectively filtering tea leaves.

[0107] When the plate-shaped member is selected as the filter 23, the plate-shaped member has a horizontally placed circular plate structure. The plate-shaped member is uniformly provided with a plurality of filter holes. The outer periphery of the plate-shaped member is close to or directly in contact with the inner peripheral wall of the tea bin 20, forming a horizontal filter layer. This design makes all tea water penetrate downward through the filter holes, thereby achieving comprehensive filtration of tea leaves. The central position of the filter 23 can be provided with a mounting hole for fixed connection with the water outlet nozzle 21, ensuring the stability of the filter 23.

[0108] When the cover-shaped member is selected as the filter 23, the cover-shaped member has an overall inverted bowl structure. The top of the cover-shaped member is arc-shaped, and the lower part expands outward to form an annular lower periphery. The surface of the cover-shaped member is also provided with a plurality of filter holes, which can be distributed in different ways on the surface of the cover body according to needs. The lower periphery of the cover-shaped member is close to or in contact with the bottom wall of the tea bin 20, forming a closed filter space.

[0109] The embodiment provides two optional filter 23 structures, thereby increasing the applicability of the product. Whether the plate-shaped structure or the cover-shaped structure, both can form a complete filter structure with the water outlet nozzle 21 and the isolation cavity, thereby achieving effective separation of tea leaves.

[0110] In an embodiment of the utility model, the peripheral wall of the tea bin 20 is provided with an annular stopper 201 protruding inward, and the outer periphery of the plate-shaped member is stopped above the annular stopper 201. The annular stopper 201 forms a cooperation structure with the plate-shaped filter 23 for supporting and positioning the plate-shaped filter 23.

[0111] Preferably, the annular stopper 201 is integrally formed when the peripheral wall of the tea bin 20 is formed, which is a step-shaped structure protruding inward. The annular stopper 201 is continuously arranged in the circumferential direction, thereby ensuring that the plate-shaped filter 23 can be uniformly supported. This structural design enables the plate-shaped filter 23 to be kept at a predetermined horizontal position and prevents displacement due to the weight of tea leaves or water flow impact during brewing.

[0112] The embodiment solves the positioning and supporting problems of the plate-shaped filter 23 by arranging the annular stopper 201 in the tea bin 20. This structural design not only improves the use reliability of the product, but also ensures the stability of the filtering effect.

[0113] In one embodiment of the present application, the magnetic valve core 22 comprises a core rod 221 and an axial magnet 222, the core rod 221 is slidably arranged on the water outlet nozzle 21 in the vertical direction, and the lower end of the core rod 221 is provided with a valve head 223 for plugging the water outlet hole H202. The axial magnet 222 is arranged at the top of the core rod 221, and the magnetic poles of the axial magnet 222 are oppositely arranged in the vertical direction.

[0114] In the present embodiment, the magnetic valve core 22 mainly consists of the core rod 221 and the axial magnet 222. The core rod 221 is an elongated member extending in the vertical direction, which is made of metal materials such as stainless steel and can freely slide inside the water outlet nozzle 21. The lower end of the core rod 221 has a valve head 223, which is matched in size and shape with the water outlet hole H202 and can achieve plugging of the water outlet hole H202. Exemplarily, the valve head 223 can adopt a structure with a sealing rubber ring, or directly use a food-grade material with a certain elasticity to ensure that a reliable seal with the water outlet hole H202 can be achieved in the closed position. The outer shape of the valve head 223 can be designed as a cone or a sphere, which not only facilitates sealing but also can reduce water flow resistance.

[0115] The axial magnet 222 is installed at the top of the core rod 221, and the magnetic poles of the axial magnet 222 are oppositely arranged in the vertical direction, i.e. the N pole and the S pole. This arrangement of magnetic poles determines the directionality of the magnetic force, so that the radial magnet 302 on the kettle cover 30 can generate an accurate vertical upward magnetic attraction force on the magnetic valve core 22. Exemplarily, the axial magnet 222 can be selected from plated permanent magnets or encapsulated permanent magnets to ensure safety in long-term use in a tea and water environment.

[0116] The structure of the magnetic valve core 22 provides guidance and support through the core rod 221, realizes magnetic force driving through the axial magnet 222, and ensures sealing effect through the valve head 223. This combined structure not only simplifies the manufacturing process, but also facilitates maintenance and replacement, and the vertical arrangement of the magnetic poles ensures the accuracy and reliability of the control.

[0117] In one embodiment of the present application, the valve head 223 is a conical structure with a diameter gradually decreasing from top to bottom, and the upper end of the water outlet hole H202 has a conical surface matched with the conical structure, so as to seal the water outlet hole H202 by contacting the conical structure with the conical surface.

[0118] In actual use, when the magnetic valve core 22 falls under the magnetic repulsion force and gravity, the tapered structure of the valve head 223 will automatically guide and accurately fall into the tapered surface of the water outlet hole H202. This automatic centering feature is due to the geometric characteristics of the tapered structure. Even if there is a slight eccentricity during the falling process of the magnetic valve core 22, the interaction between the tapered surfaces will automatically return the valve head 223 to the correct sealing position. In addition, the contact mode of the tapered surface is different from the ordinary plane contact, which can achieve more reliable sealing effect.

[0119] In an embodiment of the present application, the upper end of the water outlet nozzle 21 is provided with a plug 24, the plug 24 has a sliding hole penetrating in the vertical direction, the core rod 221 is slidingly arranged in the sliding hole, and the axial magnet 222 is located above the plug 24 and is blocked by the plug 24. Preferably, the upper end of the water outlet nozzle 21 has an internal thread, the plug 24 has an external thread, and the plug 24 is threadedly connected to the upper end of the water outlet nozzle 21. In this way, the installation of the plug 24, the core rod 221 and the water outlet nozzle 21 is facilitated.

[0120] When the magnetic valve core 22 moves upward under the magnetic attraction, the valve head 223 is blocked by the plug 24, thereby limiting the maximum upward movement height of the magnetic valve core 22. The axial magnet 222 is located above the plug 24, which ensures the reliable magnetic coupling between the axial magnet 222 and the radial magnet 302 of the kettle cover 30. This design ensures that the magnetic valve core 22 always moves within a predetermined height range, thereby ensuring the reliability of the switching of the magnetic valve core 22 between the open position and the closed position.

[0121] The present embodiment realizes reliable limitation and accurate control of the movement stroke of the magnetic valve core 22 through the design of the plug 24, thereby improving the stability and reliability of the magnetic valve core 22.

[0122] Preferably, the axial magnet 222 has an encapsulation shell 224. The encapsulation shell 224 can be made of food-grade stainless steel, for example. The full-sealing protection of the axial magnet 222 by the encapsulation shell 224 solves the potential safety hazards and service life problems that may be caused by the direct exposure of the axial magnet 222 to the tea and water environment. This structural design not only ensures the safety and durability of the product in use, but also facilitates cleaning and maintenance, and meets the hygiene requirements of food-grade products.

[0123] The cover body 301 includes an upper cover 3011 and a lower cover 3012, and the lower cover 3012 is connected with the upper cover 3011. The upper cover 3011 and the lower cover 3012 are reliably connected by buckling, threading or other detachable connection methods to form a complete cover body 301. The upper cover 3011 can be made of plastic, and the lower cover 3012 can be made of food-grade stainless steel.
