[0070] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a tea hopper assembly and a top-suction teapot having the same.

[0071] Reference Figures 1 to 3 As shown, the tea container assembly provided according to the embodiment of this utility model includes a container body 10, a water outlet 20, and a magnetic valve core 30.

[0072] Specifically, the tea bin 10 is used for containing tea leaves and brewing tea. The tea bin 10 is made of high-temperature-resistant food-grade material, such as glass, ceramic, stainless steel, etc. The tea bin 10 has a proper capacity space, and the top of the tea bin 10 is provided with an opening for facilitating the addition of tea leaves.

[0073] The water outlet 20 is arranged at the bottom of the tea bin 10 and used for discharging liquid in the tea bin 10. The water outlet 20 can be sealingly connected with the bottom of the tea bin 10, or the water outlet 20 and the bottom of the tea bin 10 are designed in an integrated manner to ensure that tea flows out of the water outlet 20 during use.

[0074] The magnetic valve core 30 is arranged on the water outlet 20 and can be switched between an open position and a closed position along the vertical direction. The magnetic valve core 30 is made of a material with magnetism and can form a magnetic coupling with the magnetic control assembly on the kettle cover 50. The magnetic control assembly can drive the magnetic valve core 30 to move upward by the magnetic adsorption force of the magnetic core, so as to switch from the closed position to the open position.

[0075] When the magnetic valve core 30 is in the closed position, the magnetic valve core 30 closes the water outlet 20. When the magnetic valve core 30 is subjected to the upward magnetic adsorption force, the magnetic valve core 30 moves upward to the open position to open the water outlet 20.

[0076] In actual use, when it is necessary to discharge tea, the user can operate the magnetic control assembly on the kettle cover 50 to make the magnetic control assembly generate an upward magnetic adsorption force on the magnetic valve core 30. Under the magnetic adsorption force, the magnetic valve core 30 overcomes the gravity and moves upward along the vertical direction until reaching the preset open position. At this time, the water outlet 20 is opened, and tea flows out of the tea bin 10 into the kettle body 40 under the action of gravity.

[0077] According to the tea bin assembly provided in the embodiment of the present application, the magnetic valve core 30 that can slide along the vertical direction is arranged on the water outlet 20, so as to realize the reliability of the opening and closing of the water outlet 20. When the magnetic valve core 30 is in the closed position, the water outlet 20 can be effectively closed to prevent tea leakage. When it is necessary to discharge tea, the magnetic control assembly on the kettle cover 50 is operated to generate an upward magnetic adsorption force, which drives the magnetic valve core 30 to move upward to the open position, so as to open the water outlet 20 and realize the discharge of tea. The vertical movement design not only simplifies the movement track of the valve core and improves the control precision, but also ensures the stability and reliability of the switching action through the directionality of the magnetic adsorption force, greatly improves the problem of uncertain movement of the magnetic ball head in the traditional tea bin, and makes the tea separation control more accurate and controllable.

[0078] In an embodiment of the present application, when the magnetic attraction force is removed, the magnetic valve core 30 can reset to the closed position under the action of its own gravity.

[0079] That is, the magnetic valve core 30 freely slides in the vertical direction relative to the water outlet nozzle 20, for example, the diameter of the magnetic valve core 30 is slightly smaller than the inner diameter of the water outlet nozzle 20, so that it can freely slide up and down, and can automatically recover to the closed position under the action of gravity.

[0080] Based on the gravity reset structure, automatic reset from the open position to the closed position is realized, the structure is simple and reliable, and the reset action is stable and responds quickly, ensuring the timeliness and reliability of tea control. No additional reset mechanism is needed, reducing manufacturing cost and maintenance difficulty.

[0081] In an embodiment of the present application, the upper end of the water outlet nozzle 20 is located in the bin body 10, and the side wall of the upper end of the water outlet nozzle 20 is provided with a water inlet hole H201.

[0082] The lower end of the water outlet nozzle 20 is fixed on the bottom wall of the bin body 10, and the lower end of the water outlet nozzle 20 has a water outlet hole H202; when the magnetic valve core 30 is located in the closed position, the magnetic valve core 30 blocks the water outlet hole H202.

[0083] That is, the upper end of the water outlet nozzle 20 extends to the inside of the bin body 10, and the lower end is fixedly installed on the bottom wall of the bin body 10. This structure design not only ensures the stable connection between the water outlet nozzle 20 and the bin body 10, but also facilitates effective collection and discharge of tea water.

[0084] The water inlet hole H201 of the upper end side wall of the water outlet nozzle 20 is used for the tea water in the bin body 10 to enter the water outlet nozzle 20. The water inlet hole H201 can be multiple, and the multiple water inlet holes H201 are distributed on the side wall of the water outlet nozzle 20 in a circumferential direction, facilitating smooth flow of tea water into the water outlet nozzle 20 and improving water inlet efficiency. The diameter of the water outlet hole H202 at the lower end of the water outlet nozzle 20 is smaller than the inner diameter of the water outlet nozzle 20, forming a contracted water outlet channel. When the magnetic valve core 30 is in the closed position, the magnetic valve core 30 can reliably block the water outlet hole H202.

[0085] When the magnetic valve core 30 moves upward under the action of the magnetic control assembly during operation, the tea water in the bin body 10 first flows into the water outlet nozzle 20 through the water inlet hole H201 at the upper end of the water outlet nozzle 20, and then flows out from the opened water outlet hole H202. When the magnetic attraction force of the magnetic control assembly is removed, the magnetic valve core 30 moves downward under the action of gravity until the bottom thereof tightly abuts against the water outlet hole H202, and returns to the closed state. This structure design makes the switching process more smooth and the sealing effect better.

[0086] In an embodiment of the present application, the tea bin assembly further comprises a filter 31, which is arranged in the bin body 10 and fixed on the water outlet nozzle 20, and a separation cavity is defined between the filter 31 and the bottom wall of the bin body 10, and the water inlet hole H201 is located in the separation cavity. The filter 31 is designed in a mesh structure and can be made of stainless steel filter mesh or other high-temperature-resistant food-grade materials.

[0087] In this embodiment, the filter 31 is arranged, and a closed separation cavity is formed between the filter 31 and the bottom wall of the bin body 10. The separation cavity is used to collect the filtered tea water and guide it to the water inlet hole H201 of the water outlet nozzle 20. In operation, the tea water in the bin body 10 first needs to pass through the filter 31, and the larger tea leaves and tea leaf debris are blocked above the filter 31. The filtered tea water enters the separation cavity and then flows into the water outlet nozzle 20 through the water inlet hole H201 on the water outlet nozzle 20. When the magnetic valve core 30 moves upward to open the water outlet hole H202, the tea water can flow out of the water outlet nozzle 20.

[0088] Through the filtration of the filter 31, the tea leaves can be effectively intercepted to prevent the larger tea leaf debris from entering the separation cavity. In addition, the separation cavity provides a buffer space for the filtered tea water, so that the tea water flows more uniformly. Moreover, since the water inlet hole H201 is located in the separation cavity, the risk of the tea leaf debris blocking the water inlet hole H201 is reduced, and the reliability of the tea water flowing into the water outlet nozzle 20 is ensured.

[0089] In an embodiment of the present application, the filter 31 is a plate-shaped member or a cover-shaped member, and a plurality of filter holes for filtering tea leaves are arranged on the filter 31.

[0090] When the filter 31 is a plate-shaped member, the outer peripheral edge of the plate-shaped member is close to or in contact with the peripheral wall of the bin body 10, and when the filter 31 is a cover-shaped member, the lower peripheral edge of the cover-shaped member is close to or in contact with the bottom wall of the bin body 10.

[0091] That is, the filter 31 can be selected in 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.

[0092] When the plate-shaped member is selected as the filter 31, it is in a horizontally placed circular plate structure. A plurality of filter holes are uniformly distributed on the plate-shaped member. The outer peripheral edge of the plate-shaped member is close to or directly in contact with the inner peripheral wall of the bin body 10, forming a horizontal filter layer. This design makes all tea water penetrate downward through the filter holes, thereby achieving comprehensive filtration of tea leaves. A mounting hole can be arranged at the central position of the filter 31 for fixed connection with the water outlet nozzle 20, ensuring the stability of the filter 31.

[0093] When the cover-shaped filter 31 is selected, the overall structure is a reversed bowl shape. The top of the cover-shaped filter is circular arc-shaped, and the lower part expands outward to form a ring-shaped lower periphery. The surface of the cover-shaped filter 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 filter is close to or in contact with the bottom wall of the bin body 10, forming a closed filter space.

[0094] The present embodiment increases the applicability of the product by providing two optional filter 31 structures. Whether it is a plate-shaped structure or a cover-shaped structure, it can form a complete filter structure with the water outlet nozzle 20 and the isolation chamber to achieve effective separation of tea leaves.

[0095] In an embodiment of the present application, the peripheral wall of the bin body 10 is provided with a ring-shaped stopper 101 protruding inward, and the outer periphery of the plate-shaped filter is stopped above the ring-shaped stopper 101. The ring-shaped stopper 101 forms a cooperating structure with the plate-shaped filter 31 for supporting and positioning the plate-shaped filter 31.

[0096] The ring-shaped stopper 101 is integrally formed when the peripheral wall of the bin body 10 is formed, and is a step-shaped structure protruding inward. The ring-shaped stopper 101 is continuously arranged in the circumferential direction, ensuring that the plate-shaped filter 31 can be uniformly supported. This structure design allows the plate-shaped filter 31 to be maintained at a predetermined horizontal position and will not be displaced due to the weight of the tea or the impact of the water flow during the brewing process.

[0097] The present embodiment solves the positioning and supporting problem of the plate-shaped filter 31 by providing a ring-shaped stopper 101 in the bin body 10. This structure design not only improves the use reliability of the product, but also ensures the stability of the filtering effect.

[0098] In some embodiments of the present application, the magnetic valve core 30 includes a core rod 301 and a magnet 302, the core rod 301 is slidably arranged on the water outlet nozzle 20 in the vertical direction, and the lower end of the core rod 301 is provided with a valve head 3011 for blocking the water outlet hole H202. The magnet 302 is arranged at the top of the core rod 301, and the N pole and the S pole of the magnet 302 are arranged opposite in the vertical direction.

[0099] In this embodiment, the magnetic valve core 30 is mainly composed of a core rod 301 and a magnet piece 302. The core rod 301 is an elongated member extending in the vertical direction and can freely slide inside the water outlet nozzle 20. The lower end of the core rod 301 is provided with a valve head 3011 which is matched in size and shape with the water outlet hole H202 and can realize the plugging of the water outlet hole H202. Exemplarily, the valve head 3011 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 realized in the closed position. The outer shape of the valve head 3011 can be designed as a cone or a sphere, which is not only beneficial to sealing but also can reduce the water flow resistance.

[0100] The magnet piece 302 is installed on the top of the core rod 301, and the arrangement of the magnetic poles of the magnet piece 302 is that the N pole and the S pole are oppositely arranged in the vertical direction. This arrangement of the magnetic poles determines the directionality of the magnetic force, so that the magnetic control assembly on the kettle cover 50 can generate an accurate vertical upward attractive force on the magnetic valve core 30. Exemplarily, the magnet piece 302 can select a plated permanent magnet or a coated permanent magnet to ensure the safety of long-term use in the tea water environment.

[0101] The structure of the magnetic valve core 30 is adopted, the core rod 301 provides guidance and support, the magnet piece 302 realizes magnetic force driving, and the valve head 3011 ensures the sealing effect. This combined structure not only simplifies the manufacturing process, but also is convenient for maintenance and replacement, and the vertical arrangement of the magnetic poles ensures the accuracy and reliability of the control.

[0102] In an embodiment of the present application, the valve head 3011 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 the contact between the conical structure and the conical surface.

[0103] In the actual working process, when the magnetic valve core 30 descends under the action of gravity, the conical structure of the valve head 3011 will automatically guide and accurately fall into the conical surface of the water outlet hole H202. This automatic centering feature is derived from the geometric characteristics of the conical structure. Even if there is a slight eccentricity in the falling process of the valve core, the interaction between the conical surfaces S201 will promote the valve head 3011 to automatically return to the correct sealing position. In addition, the contact mode of the conical surface to the conical surface is different from the ordinary plane contact, which can realize a more reliable sealing effect.

[0104] In an embodiment of the utility model, the water outlet nozzle 20 includes nozzle pipe 201, nut 202 and sealing ring 203, the nozzle pipe 201 is tubular part, the bottom of the bin body 10 is equipped with mounting hole, the nozzle pipe 201 is arranged in the mounting hole, and the outer circumferential surface of the nozzle pipe 201 has annular shoulder portion 2011 that protrudes radially outward, the annular shoulder portion 2011 is stopped above the bottom wall of the bin body 10. That is, the annular shoulder portion 2011 plays the role of positioning and supporting. When the nozzle pipe 201 passes through the mounting hole in the bottom of the bin body 10, the annular shoulder portion 2011 will be naturally stopped above the bottom wall of the bin body 10, forming a stable support point.

[0105] The nut 202 is located below the bottom wall of the bin body 10 and is threadedly connected with the lower end of the nozzle pipe 201 to fix the nozzle pipe 201 at the bottom of the bin body 10. Exemplarily, the lower end of the nozzle pipe 201 is machined with external threads for cooperation with the nut 202, and the nozzle pipe 201 can be firmly fixed at the bottom of the bin body 10 through the threaded connection between the nut 202 and the lower end of the nozzle pipe 201. In the tightened state of the nut 202, sufficient fastening force can be provided, and at the same time, disassembly and maintenance are facilitated.

[0106] The sealing ring 203 is sleeved on the nozzle pipe 201. The sealing ring 203 is located between the nut 202 and the bottom wall of the bin body 10, or the sealing ring 203 is located between the annular shoulder portion 2011 and the bottom wall of the bin body 10, so that a good sealing effect between the nozzle pipe 201 and the bottom of the bin body 10 can be ensured, and the tea water in the bin body 10 can only be discharged through the nozzle pipe 201.

[0107] The magnetic valve core 30 is slidably arranged in the upper end of the nozzle pipe 201, the water inlet hole H201 is arranged on the outer circumferential wall of the nozzle pipe 201 and located above the annular shoulder portion 2011, and the water outlet hole H202 is arranged on the lower end of the nozzle pipe 201. The upper end of the nozzle pipe 201 serves as a sliding channel of the magnetic valve core 30, and the diameter of the core rod 301 of the magnetic valve core 30 is slightly smaller than the inner diameter of the nozzle pipe 201, so that the magnetic valve core 30 slides up and down more smoothly and reliably.

[0108] The combined structure of the water outlet nozzle 20 realizes detachable design through cooperation of the nozzle pipe 201, the nut 202 and the sealing ring 203, facilitates installation, maintenance and cleaning, and in the actual installation process, the nozzle pipe 201 is inserted into the mounting hole in the bottom of the bin body 10, so that the annular shoulder portion 2011 contacts the bottom wall. Then the sealing ring 203 is installed, and finally the nut 202 is tightened, so that the installation of the entire water outlet nozzle 20 is completed. The cooperation of the annular shoulder portion 2011 and the nut 202 ensures stable connection, and the sealing ring 203 ensures reliable sealing effect.

[0109] In an embodiment of the utility model, the water outlet 20 further comprises a threaded plug 204, the threaded plug 204 has external threads, the upper end of the nozzle pipe 201 has internal threads matched with the external threads, that is, the threaded plug 204 is threadedly connected with the upper end of the nozzle pipe 201. The valve head 3011 is located below the threaded plug 204 to limit the stroke of the core rod 301 through the threaded plug 204, which can prevent the magnetic valve core 30 from being separated from the nozzle pipe 201 and ensure the stable assembly relationship therebetween.

[0110] The threaded plug 204 has a sliding hole penetrating in the vertical direction, the core rod 301 is slidably arranged in the sliding hole, and the magnet piece 302 is located above the threaded plug 204 and is blocked by the threaded plug 204. When the magnetic valve core 30 moves upward under the action of the magnetic force, the magnet piece 302 is blocked by the threaded plug 204, thereby limiting the maximum upward height of the magnetic valve core 30. The magnet piece 302 is located above the threaded plug 204, thereby ensuring the reliable magnetic coupling between the magnet piece 302 and the magnetic control assembly on the kettle cover 50. This design ensures that the magnetic valve core 30 always moves within a predetermined height range, thereby ensuring the reliability of switching of the magnetic valve core 30 between the open position and the closed position.

[0111] The embodiment realizes reliable limitation and accurate control of the movement stroke of the magnetic valve core 30 through the design of the threaded plug 204, and the stability and reliability of the magnetic valve core 30 are improved.

[0112] Preferably, the magnet piece 302 comprises an encapsulation shell 3021 and a first magnet 3022 arranged in the encapsulation shell 3021, and the encapsulation shell 3021 can be made of food-grade stainless steel, for example. The first magnet 3022 is fully sealed and protected by the encapsulation shell 3021, thereby solving the safety hazard and service life problem that the magnet is directly exposed to the tea 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 contact products.

[0113] Referring to Figure 4 The utility model embodiment further provides a top suction type tea kettle, which comprises a kettle body 40, a tea bin assembly and a kettle cover 50 as described in the above embodiment.

[0114] Specifically, the tea bin assembly is arranged in the spout of the kettle body 40.

[0115] The kettle cover 50 is covered on the bin body 10, and a second magnet 501 capable of changing the magnetic pole direction is arranged in the kettle cover 50.

[0116] When the second magnet 501 is operated by a user to change the magnetic pole direction, the magnetic attraction force between the second magnet 501 and the magnetic valve core 30 drives the magnetic valve core 30 to move upward to open the water outlet nozzle 20.

[0117] Preferably, the kettle cover 50 is further provided with a driving member for driving the second magnet 501 to rotate, the driving member and the second magnet 501 forming a magnetic control assembly, and the driving member can be a manual driving member or a driving motor. When the driving member drives the second magnet 501 to rotate by a predetermined angle, the directions of the N pole and the S pole can be changed. For example, the driving member drives the second magnet 501 to rotate by 180°, so that the N pole is turned upward and the S pole is turned downward. At this time, the S pole of the second magnet 501 is opposite to the N pole of the first magnet 3022 on the magnetic valve core 30, and an attractive force is generated, which drives the magnetic valve core 30 to move upward, so as to open the water outlet hole H202.

[0118] According to the top suction type tea kettle provided in the embodiment of the present application, the magnetic valve core 30 which can slide in the vertical direction is arranged on the water outlet nozzle 20 in the tea bin assembly, so as to realize the reliability of the opening and closing of the water outlet nozzle 20. When the magnetic valve core 30 is in the closed position, the water outlet nozzle 20 can be effectively closed to prevent tea water from leaking. When it is needed to discharge tea water, the second magnet 501 is operated to generate an upward magnetic attraction force, which drives the magnetic valve core 30 to move upward to the open position, so as to open the water outlet nozzle 20 to realize the discharge of tea water. The movement design in the vertical direction not only simplifies the movement track of the valve core and improves the control precision, but also ensures the stability and reliability of the opening and closing action through the directionality of the magnetic attraction force, greatly improves the problem of uncertain movement of the magnetic ball head in the traditional tea bin, and makes the control of tea water separation more accurate and controllable.
