[0061] The top suction type tea making kettle provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] Referring to Figures 1 to 10 As shown in the drawings, the top suction type tea making kettle provided by the embodiments of the present application comprises a kettle body 10, a tea bin assembly 20 and a kettle cover 30.

[0063] Specifically, the kettle body 10 is usually made of glass, ceramic, metal or the like, has a certain volume, and is used to hold the tea water after brewing. The kettle body 10 can be provided with a spout for pouring out the tea water.

[0064] The tea bin assembly 20 comprises a tea bin 201, a water outlet nozzle 202 and a magnetic valve core 203. The tea bin 201 is arranged in the spout of the kettle body 10. The tea bin 201 is used for containing tea and brewing tea. The tea bin 201 can be configured in various shapes, for example, the tea bin 201 is cylindrical, and a hanging rim is arranged at the upper end of the tea bin 201 to hang on the spout of the kettle body 10, or the tea bin 201 is conical, and the conical tea bin 201 is stacked in the spout of the kettle body 10. The tea bin 201 is made of high-temperature-resistant food-grade materials, such as glass, ceramic, stainless steel, etc. The top of the tea bin 201 is provided with an opening for adding tea and warm water.

[0065] The water outlet nozzle 202 is arranged at the bottom of the tea bin 201 and used for discharging tea water in the tea bin 201. The upper end of the water outlet nozzle 202 is located in the tea bin 201 and has a first central hole H2c. The lower end of the water outlet nozzle 202 is located outside the tea bin 201 and has a second central hole H2d and a water outlet hole H2b. The peripheral wall of the water outlet nozzle 202 is provided with a water inlet hole H2a for allowing tea water in the tea bin 201 to flow into the water outlet nozzle 202.

[0066] Tea water in the tea bin 201 can flow into the water outlet nozzle 202 through the water inlet hole H2a and then flow out of the water outlet hole H2b at the lower end of the water outlet nozzle 202 into the kettle body 10 below. The water outlet nozzle 202 and the bottom of the tea bin 201 can be sealingly connected or integrally designed to ensure that tea water flows out of the water outlet nozzle 202 during use.

[0067] The magnetic valve core 203 is arranged in the water outlet nozzle 202 and has magnetic poles arranged oppositely in the up-down direction. The oppositely arranged magnetic poles in the up-down direction can form a stable magnetic coupling relationship with the magnetic control on the kettle cover 30, facilitating the driving of the magnetic valve core 203 by the magnetic control. In addition, the magnetic valve core 203 is located inside the water outlet nozzle 202, and the water outlet nozzle 202 only allows tea water to flow in. Therefore, during use, the magnetic valve core 203 moves completely inside the water outlet nozzle 202 and is not interfered or hindered by tea, ensuring the stability and reliability of the opening and closing of the magnetic valve core 203 to the water outlet hole H2b.

[0068] The upper end of the magnetic valve core 203 has a first positioning column 2033a, and the lower end of the magnetic valve core 203 has a second positioning column 2031a; the first positioning column 2033a is in sliding fit with the first center hole H2c, and the second positioning column 2031a is in sliding fit with the second center hole H2d. Through the sliding fit of the first positioning column 2033a with the first center hole H2c and the second positioning column 2031a with the second center hole H2d, the magnetic valve core 203 has good guiding and positioning effects during the upward and downward movement in the water outlet nozzle 202, thereby ensuring the stable and reliable upward and downward movement of the valve core.

[0069] The kettle cover 30 is arranged on the top of the tea bin 201, and the kettle cover 30 is provided with a magnetic control device configured to form a magnetic attraction force with the magnetic valve core 203 under the operation of a user, so as to drive the magnetic valve core 203 to move upward to open the water outlet nozzle 202 by the magnetic attraction force, and when the magnetic attraction force is removed, the magnetic valve core 203 can automatically fall under the action of gravity to close the water outlet hole H2b.

[0070] The magnetic control device also has a magnetic effect and forms a magnetic coupling relationship with the magnetic valve core 203, and the magnetic effect between the magnetic control device and the magnetic valve core 203 can be changed by operating the magnetic control device, for example, rotating the magnetic control device to change the magnetic pole direction. When the magnetic attraction force is generated between the magnetic control device and the magnetic valve core 203, the magnetic valve core 203 can slide upward to open the water outlet hole H2b, so that the tea flows into the kettle body 10 below. After the tea is discharged, the magnetic control device can be operated to reset, so that the magnetic attraction force between the magnetic control device and the magnetic valve core 203 is switched to the magnetic repulsion force, at this time, the magnetic valve core 203 automatically falls under the action of gravity to reseal and close the water outlet hole H2b. In this way, the opening and closing control of the water outlet hole H2b can be realized.

[0071] According to the embodiment of the utility model provides top suction type tea making kettle, magnetic valve core 203 is built -in in water outlet 202, and the upper end of magnetic valve core 203 is equipped with first locating post 2033a, the lower end of magnetic valve core 203 is equipped with second locating post 2031a, the upper end of water outlet 202 is equipped with the first center hole H2c of sliding cooperation with first locating post 2033a, and the lower end of water outlet 202 is equipped with the second center hole H2d of sliding cooperation with second locating post 2031a. Magnetic control is equipped on the kettle cover 30, by operating the magnetic control on the kettle cover 30, make its to magnetic valve core 203 produce magnetic attraction, drive magnetic valve core 203 to slide upwards and open water hole H2b, in addition, magnetic valve core 203 can also fall automatically under the action of gravity and close water hole H2b. Since magnetic valve core 203 is completely in water outlet 202, prevent the interference of tea to magnetic valve core 203, simultaneously, the sliding cooperation of first locating post 2033a and first center hole H2c, second locating post 2031a and second center hole H2d, guarantee that magnetic valve core 203 slides stably and reliably in water outlet 202, thereby, can significantly improve the stability and reliability of the opening and closing of water hole H2b, improve user experience and the overall performance of product.

[0072] Referring to Figure 6 As shown in the utility model, in some embodiments, the water outlet 202 has a valve cavity, and the magnetic valve core 203 is arranged in the valve cavity.

[0073] The valve cavity includes a cylindrical cavity P2a and a conical cavity P2b connected together. The diameter of the cylindrical cavity P2a is greater than the outer diameter of the magnetic valve core 203. When the magnetic valve core 203 is installed in the valve cavity, an annular gap cavity is formed between the outer circumferential surface of the magnetic valve core 203 and the inner circumferential surface of the cylindrical cavity P2a. The tea water in the tea bin 201 enters the annular gap cavity through the water inlet hole H2a on the peripheral wall of the water outlet 202.

[0074] The conical cavity P2b is located below the cylindrical cavity P2a, and the water outlet hole H2b is located below the conical cavity P2b and communicates with the cylindrical cavity P2a through the conical cavity P2b. That is, the cylindrical cavity P2a, the conical cavity P2b and the water outlet hole H2b are sequentially connected from top to bottom. The tea water in the cylindrical cavity P2a needs to pass through the conical cavity P2b to flow out from the water outlet hole H2b.

[0075] The lower end of the magnetic valve core 203 has a conical water sealing surface S2 matched with the inner wall of the conical cavity P2b. When the magnetic valve core 203 falls under its own gravity, the conical water sealing surface S2 is in close contact with the inner wall of the conical cavity P2b to block the communication between the cylindrical cavity P2a and the water outlet hole H2b.

[0076] In specific use, in the initial state, the magnetic control and the magnetic valve core 203 are in magnetic repulsion, at this time, the magnetic valve core 203 keeps falling and sealing state under the gravity and the magnetic repulsion, in the sealing state, the conical water sealing surface S2 at the lower end of the magnetic valve core 203 is attached to the inner wall of the conical cavity P2b, the conical cavity P2b is sealed, and the communication between the water outlet hole H2b and the cylindrical cavity P2a is blocked, at this time, the water outlet hole H2b is closed, and the tea water in the cylindrical cavity P2a cannot flow into the water outlet hole H2b. When it is needed to open the water outlet hole H2b, the magnetic control can be operated to switch the magnetic repulsion between the magnetic control and the magnetic valve core 203 to magnetic attraction, the magnetic valve core 203 moves upward under the action of the magnetic attraction, and then the conical water sealing surface S2 at the lower end of the magnetic valve core 203 is separated from the inner wall of the conical cavity P2b, the conical cavity P2b is opened, and the tea water in the cylindrical cavity P2a can flow into the water outlet hole H2b through the conical cavity P2b, and then flow out from the water outlet hole H2b to the kettle 10 below, so that the tea water is discharged.

[0077] In the embodiment, the conical cavity P2b realizes automatic sealing and closing by the conical structure. When the user drives the magnetic valve core 203 to slide upward by the magnetic control, the conical water sealing surface S2 is separated from the inner wall of the conical cavity P2b, so that the water outlet hole H2b and the cylindrical cavity P2a realize water communication; and after the magnetic valve core 203 naturally falls under the action of gravity, the conical water sealing surface S2 quickly restores the sealing state, so as to prevent the tea water from flowing out accidentally. The structure design can automatically center during the gravity falling process, better attachment is realized, and the reliability of automatic water sealing is improved.

[0078] Referring to Figures 4 to 6 As shown in the figure, in some embodiments of the utility model, the magnetic valve core 203 includes a valve shell and an axial magnet 2032 packaged in the valve shell, the valve shell can adopt food-grade stainless steel material, on the one hand, the stainless steel material has the characteristics of high strength, corrosion resistance and meeting the food-grade hygiene requirements, on the other hand, the stainless steel material has large mass, and can realize the function of falling water sealing by the gravity of the stainless steel material itself.

[0079] The axis of the axial magnet 2032 extends in the up-down direction, and the axial magnet 2032 refers to a magnet with two magnetic poles arranged opposite in the axial direction. The axial magnet 2032 can better cooperate with the magnetic control, for example, the magnetic control can also adopt magnetic poles arranged opposite in the up-down direction, in this way, the magnetic control and the axial magnet 2032 can change the magnetic force between them by rotating the magnetic control to change the direction of the magnetic pole, for example, rotating the magnetic control by 180° to exchange the N pole and the S pole, and then switching the magnetic force between the magnetic control and the axial magnet 2032 between repulsion and attraction.

[0080] The first positioning column 2033a is located at the top of the valve shell, and the second positioning column 2031a is located at the bottom of the valve shell. The first center hole H2c at the upper end of the water outlet nozzle 202 and the second center hole H2d at the lower end of the water outlet nozzle 202 are conveniently and slidably matched, so that the magnetic valve core 203 can smoothly and stably slide in the water outlet nozzle 202.

[0081] In the embodiment, the axial magnet 2032 is encapsulated in the valve shell, so that the axial magnet 2032 cannot be in contact with tea water, and the hygiene and safety are improved. In addition, the reliability of the movement of the magnetic valve core 203 in the water outlet nozzle 202 is improved, and the reliability and stability of the switch control of the water outlet nozzle 202 are improved.

[0096] Referring to Figures 1 to 2 and Figures 9 to 10 In some embodiments of the utility model, the magnetic control device comprises a radial magnet 302 and a driving member, the radial magnet 302 is arranged in the kettle cover 30, and the radial magnet 302 has an axis extending in the horizontal direction and opposite magnetic poles in the radial direction. This arrangement makes the N and S poles of the radial magnet 302 change direction when it rotates in the vertical plane, and thus can more reliably switch the magnetic force between the magnetic valve core 203 at the bottom of the tea bin 201.

[0097] A driving member is arranged on the lid 30 and connected with the radial magnet 302, to drive the radial magnet 302 to rotate a predetermined angle along the axis to change the magnetic pole direction of the radial magnet 302, so that the magnetic attraction and magnetic core repulsion between the radial magnet 302 and the magnetic valve core 203 is switched. The driving member can adopt an electric driving structure such as a motor, or a structure such as a knob or a lever which is convenient for manual operation.

[0098] That is, the radial magnet 302 is driven by the driving member to rotate a predetermined angle around its horizontal axis, so as to change the direction of the N pole and S pole of the radial magnet 302. When the magnetic pole direction of the radial magnet 302 is changed, the magnetic action between the radial magnet 302 and the magnetic valve core 203 at the bottom of the tea bin 201 is changed, for example, from magnetic repulsion to magnetic attraction, and then under the magnetic attraction, the magnetic valve core 203 moves upward, so as to open the water outlet nozzle 202 at the bottom of the tea bin 201. When the driving member drives the radial magnet 302 to reset, the N pole and S pole of the radial magnet 302 return to the initial state, at this time, the magnetic action between the radial magnet 302 and the magnetic valve core 203 at the bottom of the tea bin 201 is switched to magnetic repulsion again, under the dual action of magnetic repulsion and the gravity of the magnetic valve core 203, the magnetic valve core 203 resets downward, so as to close the water outlet nozzle 202 at the bottom of the tea bin 201.

[0099] In actual application, when the magnetic valve core 203 in the water outlet nozzle 202 needs to be controlled, the operator only needs to control the driving member on the lid 30. The rotation of the driving member drives the radial magnet 302 to rotate, so that the direction of the N pole and S pole of the radial magnet 302 is changed, so as to control the action of the magnetic valve core 203 at the bottom of the tea bin 201 through magnetic force, and then realize the opening or closing of the water outlet nozzle 202. This control mode is intuitive and simple, and convenient and reliable to operate.

[0100] In this embodiment, the radial magnet 302 is arranged in the lid 30 and adopts a horizontal rotation control mode, and the lid 30 is located above the tea bin assembly 20, so the direction of the magnetic action between the radial magnet 302 and the magnetic valve core 203 is vertical, and then the upward and downward movement of the magnetic valve core 203 can be controlled, and the reliability of the opening and closing of the magnetic valve core 203 is improved. At the same time, the axial magnet 2032 and the driving member and other control components are integrated in the lid 30, which is simple in structure and convenient to operate.

[0101] Reference Figure 9 and Figure 10As shown in the utility model, in one embodiment of the utility model, the driving member comprises a driving motor 303, a circuit board 304, an operation button 306 and a battery 305, the driving motor 303 is fixed in the kettle cover 30, and the output shaft of the driving motor 303 is connected with the radial magnet 302, to drive the radial magnet 302 to rotate around the axis. Exemplarily, the driving motor 303 can adopt a micro motor, and is fixedly installed in the internal space of the kettle cover 30, rotates through the output shaft of the driving motor 303, thereby driving the radial magnet 302 to rotate around the horizontal axis thereof.

[0102] The circuit board 304 is arranged in the kettle cover 30, and is electrically connected with the driving motor 303, to control the driving motor 303. The operation button 306 is electrically connected with the circuit board 304, to be operated by a user to control the driving motor 303. The battery 305 is electrically connected with the circuit board 304, to supply power for the circuit board 304. Exemplarily, the operation button 306 can adopt a touch button or a mechanical button, and the battery 305 can adopt a rechargeable battery 305, and a charging interface 308 for charging the rechargeable battery 305 is arranged on the kettle cover 30, and an interface cover 309 can be arranged on the charging interface 308.

[0103] In use, the user only needs to touch or press the operation button 306, to generate a control signal, and the circuit board 304 controls the start-stop and steering of the driving motor 303 according to the control signal, thereby driving the radial magnet 302 to rotate by a predetermined angle, changing the direction of the N pole and the S pole of the radial magnet 302, to control the action of the magnetic valve core 203, to realize the opening or closing control of the water outlet nozzle 202, and the operation is simple and convenient, and the control is reliable and stable.

[0104] Reference Figure 10 As shown in the utility model, in one embodiment of the utility model, the driving member further comprises a limiting member, the limiting member is connected on the output shaft of the driving motor 303, to limit the predetermined angle to 180 degrees.

[0105] One magnetic pole of the radial magnet 302 faces upward, and the other magnetic pole faces downward, to form the magnetic line distribution in the vertical direction. The rotation angle of the radial magnet 302 can be limited to 180 degrees by the limiting member. When the driving member drives the radial magnet 302 to rotate by 180 degrees, the upper and lower magnetic pole positions 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. The 180-degree reversal design ensures the complete switching of the magnetic force, that is, from the strongest attraction state to the strongest repulsion state, or vice versa.

[0106] The embodiment realizes switching of opening or closing of the magnetic valve core 203 through 180° magnetic pole reversal, and the switching action is crisp and neat, and the reliability of switching is improved.

[0107] Exemplarily, the limiting piece is a shaft connecting limiter 307 connected between an output shaft of the driving motor 303 and the radial magnet 302. The shaft connecting limiter 307 has a limiting protrusion 3071 on an outer periphery thereof, and the kettle cover 30 is provided with a stop portion. When the radial magnet 302 rotates 180° along the axis, the limiting protrusion 3071 abuts against the stop portion. The stop portion can adopt various forms, can be a separate component provided in the kettle cover 30, or can be an inner wall or other protruding structure in the kettle cover 30, as long as it can stop the limiting protrusion 3071.
