Description

Technical Field

[0001] This utility model relates to the field of tea brewing technology, specifically an automatic tea brewing machine. Background Technology

[0002] Tea is a treasure of traditional Chinese culture, and modern people increasingly pursue a high-quality tea-drinking experience. The traditional tea-brewing process requires not only various utensils such as teapots, teacups, and tea trays, but also precise control of water temperature, time, and tea quantity, making it a complex process that demands a high level of skill from the operator. To simplify the process, various automatic tea-brewing machines have emerged on the market. Automatic tea-brewing heating systems are devices that can automatically complete the tea-brewing process. They use automation technology to achieve steps such as brewing, heating, and filtering of tea leaves, thereby improving the convenience and consistency of tea brewing.

[0003] A typical tea maker includes a main body, a water tank, a tea container, an intelligent control system, and a heating device. The main body is the basic structure of the automatic tea maker, supporting other components. The water tank supplies water to the tea container. The intelligent control system controls the operation of each part of the main body. The heating device provides water at different temperatures. Tea leaves are placed in the tea container, and the control system then controls the water from the water tank to enter the tea container, ensuring that the water flows into full contact with the tea leaves. The user places a cup under the main body, and after brewing, the tea will flow out from the water outlet of the main body.

[0004] However, since different teas require different steeping times, and the tea container does not have an automatic separation function, users may forget to let the tea steep for too long. If the tea leaves are soaked in the tea water for a long time, it will affect the taste of the tea soup.

[0005] Based on this, this utility model designs an automatic tea brewing machine to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: The tea container includes a thermos, a tea filter box, a support frame, a first filter screen, and a driving device. The thermos has a water inlet at its top. The tea filter box is rotatably disposed inside the thermos, with its top opening located below the water inlet. A second filter screen is disposed at the bottom of the tea filter box. The support frame is fixedly installed inside the thermos. The first filter screen is fixedly installed on the support frame and stacked opposite to the second filter screen at the bottom of the tea filter box. Both the first and second filter screens have mesh openings of different sizes. The driving device includes a motor and a rotating rod. One end of the rotating rod is connected to the tea filter box to drive its rotation, and the other end is coaxially connected to the output shaft of the motor. The motor is electrically connected to the controller, which is configured to start the motor and drive the tea filter box and its bottom second filter screen to rotate relative to the fixed first filter screen.

[0007] By adopting the above technical solution, the controller precisely controls the motor to drive the tea filter box to rotate, thereby changing the overlap area of ​​the mesh between the fixed first filter screen and the rotating second filter screen, achieving stepless and precise control of the tea filtration speed. This allows users to customize or automatically control the contact time between tea leaves and water according to the characteristics of different teas, fundamentally solving the technical problem of tea becoming bitter due to prolonged steeping. Furthermore, the fully automatic process requires no manual intervention, ensuring the best taste of the tea while improving ease of use and safety.

[0008] Preferably, the support frame has a limiting protrusion that contacts the outer peripheral wall of the tea filter box to limit its radial sway.

[0009] By adopting the above technical solution, the limiting protrusion contacts the outer peripheral wall of the tea filter box, effectively limiting the radial runout and swaying of the tea filter box during rotation, ensuring the stability and concentricity of the tea filter box during rotation. This not only makes the relative rotation of the two filter layers more precise and reliable, ensuring the consistency of the filtration effect, but also helps to reduce vibration and noise, and extend the service life of the motor and the entire drive device.

[0010] Preferably, the support frame has a shaft hole, and the rotating rod is rotatably inserted into the shaft hole via a bearing.

[0011] By adopting the above technical solutions, the bearings ensure smooth rotation of the rotating rod and low frictional resistance, resulting in lighter motor load, more precise control, improved product reliability and durability, and more convenient assembly and disassembly of the tea caddy.

[0012] Preferably, the top of the insulated container is detachably provided with an insulated cover, and an insulated ring extends from the lower surface of the insulated cover. When the insulated cover is closed, the insulated ring is inserted into and abuts against the inner wall of the tea filter box.

[0013] By employing the above technical solution, the heat-insulating ring is inserted into the inner wall of the tea filter box when closed, forming a physical barrier that greatly reduces heat loss from the inside of the tea filter box to the outside through convection and radiation. This design ensures that the tea leaves remain in a suitable temperature environment during brewing, which is conducive to the full release of the tea's flavor.

[0014] Preferably, the controller has multiple tea brewing programs pre-stored, each program corresponding to a different motor rotation angle and timing, to adapt to the steeping time required for different teas.

[0015] By adopting the above technical solution, the controller can automatically call the corresponding program, control the motor to execute precise rotation angles and timing, and intelligently reproduce the best brewing process for various teas, realizing the automation and popularization of professional-level tea art.

[0016] In summary, this application offers the following beneficial technical advantages: the controller precisely controls the rotation of the tea filter box driven by the motor, thereby changing the overlap area of ​​the mesh between the fixed first filter screen and the rotating second filter screen, achieving stepless and precise control over the tea filtration speed. This allows users to customize or automatically control the contact time between tea leaves and water according to the characteristics of different teas, fundamentally solving the technical problem of bitter tea caused by prolonged steeping. Furthermore, the fully automatic process requires no manual intervention, ensuring the best taste of the tea while improving ease of use and safety. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] An automatic tea brewing machine includes a body 1, a tea chamber 2 mounted on the body, and a controller 11. The tea chamber 2 includes a thermos jar 5, a tea filter box 6, a support frame 12, a first filter screen 9, and a drive device. The body 1 has an operating interface. The thermos jar 5 has a water inlet 4 at its top. The tea filter box 6 is rotatably mounted inside the thermos jar 5, with its top opening below the water inlet 4. A second filter screen 7 is located at the bottom of the tea filter box 6. The support frame 12 is fixedly installed inside the thermos jar 5, and the first filter screen 9 is fixedly installed on the support frame 12. The second filter screen 7 at the bottom of the tea box 6 is stacked and arranged opposite each other. Both the first filter screen 9 and the second filter screen 7 have mesh holes 8, and the mesh holes 8 on the first filter screen 9 and the second filter screen 7 are of different sizes. The driving device includes a motor 3 and a rotating rod 10. One end of the rotating rod 10 is connected to the tea filter box 6 to drive it to rotate, and the other end is coaxially connected to the output shaft of the motor 3. The motor 3 is electrically connected to the controller 11. The controller 11 is configured to control the motor 3 to start and drive the tea filter box 6 and the second filter screen 7 at its bottom to rotate relative to the fixed first filter screen 9.

[0023] The user places tea leaves into the tea filter box 6, selects the tea type through the operation interface on the main unit 1, and starts the machine. Hot water is injected into the tea filter box 6 through the water inlet 4, and the tea leaves begin to steep. At this time, the mesh 8 of the two filter screens are offset (minimum overlap), the effective area of ​​the filter holes is minimal, and the tea soup flows out very slowly, ensuring thorough steeping of the tea leaves. When the steeping time set by the current tea program is reached, the controller 11 sends a command to the motor 3, driving the rotating rod 10 to rotate the tea filter box 6 and the second filter screen 7 at its bottom by a predetermined angle. Since the first filter screen 9 is fixed, the rotation of the second filter screen 7 changes the overlap area of ​​the mesh 8 of the two filters. After rotation, the effective area of ​​the filter holes increases, and the tea soup quickly flows out into the insulated tank 5, thus achieving rapid "tea soup separation" and perfectly ending the steeping process. The user can control the degree of opening and closing of the filter screens through the program according to the characteristics of the tea leaves, thereby precisely controlling each stage of the steeping process.

[0024] The support frame 12 has protruding limiting protrusions 17 that contact the outer peripheral wall of the tea filter box 6 to limit its radial sway. The evenly distributed circumferential limiting protrusions 17 form a reliable positioning ring, completely constraining the radial movement freedom of the tea filter box 6. This ensures that the rotation axis of the tea filter box 6 always coincides with the axis of the rotating rod 10, thereby ensuring that the first filter screen 9 fixedly installed on the support frame 12 and the second filter screen 7 fixed to the bottom of the tea filter box 6 always remain parallel, with a uniform gap between them. This makes the relative rotation of the two filter screens more precise and smooth, avoiding problems such as misalignment of the mesh 8, friction wear, or even jamming caused by eccentric swaying, greatly improving the reliability and durability of the product.

[0025] The support frame 12 has a shaft hole 14, and the rotating rod 10 is rotatably inserted into the shaft hole 14 through the bearing 13. The sealed bearing 13 provides the main radial support, ensuring that the rotating rod 10 rotates smoothly and has high concentricity, thus improving the reliability of the product and making the tea bin 2 easier to disassemble and assemble.

[0026] The top of the insulated container 5 is detachably equipped with an insulated cover 15. An insulated ring 16 extends from the lower surface of the insulated cover 15. When the insulated cover 15 is closed, the insulated ring 16 is inserted into and abuts against the inner wall of the tea filter box 6. By setting the insulated cover 15 with the flexible insulated ring 16, a highly efficient physical heat insulation barrier is formed when closed. The close contact between the flexible insulated ring 16 and the inner wall of the tea filter box 6 greatly prevents the hot steam and heat inside the tea filter box 6 from being lost from the top through convection and radiation, retaining the heat in the tea filter box 6 to the maximum extent, which is conducive to the full release of tea flavor.

[0027] The controller 11 has multiple tea brewing programs pre-stored. Each program corresponds to a different rotation angle and timing of the motor 3 to adapt to the steeping time required for different teas. The program controls the motor 3 to drive the tea filter box 6 to rotate to a predetermined angle so that the mesh 8 of the two filter screens are in a state of minimum overlap. At this time, the tea soup can only seep out very slowly, and the tea leaves can be fully steeped. Through precise digital control of the rotation angle and timing of the stepper motor 3, precise management of the core steeping process is achieved.

[0028] The implementation principle of this embodiment is as follows: During use, the user opens the heat preservation cover 15, places tea leaves into the tea filter box 6, aligns the rotating rod 10 with the shaft hole 14, inserts it, and connects the rotating rod 10 to the support frame 12. The heat preservation cover 15 is then closed, and the user selects the tea type through the operating interface on the machine body 1 and starts the process. Hot water is injected into the tea filter box 6 through the water inlet 4, and the tea begins to steep. At this time, the mesh 8 of the two filter screens are staggered, the effective area of ​​the filter holes is minimized, and the tea soup flows out very slowly, achieving full steeping of the tea leaves. When the steeping time set by the current tea program is reached, the controller 11 sends a command to the motor 3, driving the rotating rod 10 to rotate the tea filter box 6 and its bottom second filter screen 7 by a predetermined angle. Since the first filter screen 9 remains stationary, the rotation of the second filter screen 7 changes the overlapping area of ​​the mesh 8 of both screens. After rotation, the effective area of ​​the filter holes increases, and the tea soup quickly flows out into the heat preservation tank 5, thus achieving rapid "tea soup separation" and perfectly terminating the steeping process. Users can control the degree of opening and closing of the filter screen through the program according to the characteristics of the tea, thereby precisely controlling each stage of the steeping process.
