Description

Technical Field

[0001] This invention relates to the field of tea brewing machine technology, and more particularly to a capsule tea brewing machine. Background Technology

[0002] Tea capsules are a new type of tea brewing method that encapsulates pre-processed tea leaves. Their core advantages lie in their ease of use and time-saving benefits. Tea brewed using tea capsules retains its high quality, making them popular with consumers.

[0003] However, in traditional tea brewing machines, the brewing mechanism punctures the top and bottom surfaces of the tea capsule, and a water pipe is installed inside the puncture device. Water flows unidirectionally into the capsule from top to bottom for tea extraction. This one-way water flow brewing method can affect the final taste and flavor profile of teas such as oolong and pu-erh, which require specific brewing conditions to fully release their internal substances, thus failing to fully satisfy consumers' pursuit of the best taste experience. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the existing single-direction water flow brewing method cannot meet the brewing conditions of oolong tea, pu-erh tea, etc., and proposes a capsule tea brewing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A capsule tea maker includes a body and a control panel mounted on the body. The body has a water storage cavity and a tea dispensing part integrally connected to the body. A first cover is magnetically attached to the top of the water storage cavity, and a second cover is magnetically attached to the top of the tea dispensing part. A water outlet is provided between the first and second covers. A limiting ring for carrying tea capsules is fixedly connected to the inner wall of the tea dispensing part. A puncturing needle is fixedly connected to the bottom of the second cover. A drain outlet is provided at the bottom of the tea dispensing part. A motor is fixedly connected to the bottom of the tea dispensing part. A cylinder is fixedly connected to the output end of the motor. A tea extraction part is fixedly connected to the output end of the cylinder. A heating part is provided on the body below the tea dispensing part.

[0007] Preferably, the bottom end of the second cover is fixedly connected to an abutment ring that cooperates with the limiting ring to limit the contact between the tea capsule and the cap.

[0008] Preferably, the water outlet includes:

[0009] A water pump, which is fixedly installed on the first cover;

[0010] The first handle is fixedly installed on the top of the first cover.

[0011] A water pipe, one end of which extends to the outside of the water storage cavity via the first handle, and the other end of which extends into the water storage cavity via the water pump and the first cover;

[0012] The second handle is fixedly installed at the top of the second cover.

[0013] A through hole is provided at the center of the second handle.

[0014] A nozzle, which is fixedly connected to the other end of the water pipe;

[0015] A water outlet pipe is fixedly connected to the nozzle, and a connecting pipe is slidably fitted into the through hole.

[0016] Preferably, both the first handle and the second handle consist of a cylinder and a disc.

[0017] Preferably, a connecting pipe connected to the water storage chamber is fixedly connected to the body, a water level detector is fixedly installed on the inner wall of the water storage chamber, and an alarm electrically connected to the water level detector is fixedly installed on the outer wall of the body.

[0018] Preferably, the puncture needle consists of a cone and a frustum, wherein the height of the frustum at the upper end is three times the height of the cone at the lower end.

[0019] Preferably, the drain outlet consists of two semi-circular annular through holes, and the bottom end of the tea outlet is an annular inclined slope.

[0020] Preferably, the tea extraction section includes:

[0021] A tea filter plate is fixedly connected to the cylinder, and the tea filter plate moves against the inner wall of the tea outlet section.

[0022] A cutting blade, which is fixedly connected to the tea filter plate;

[0023] A stirring rod, which is fixedly connected to the center of the tea filter plate;

[0024] The flow guide channels are symmetrically formed on the stirring rod.

[0025] Preferably, the tea filter plate has a frustum-shaped structure, the top of the stirring rod has a conical structure, and the cross-section of the guide channel is an isosceles trapezoid that is wider at the top and narrower at the bottom.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. This invention is equipped with a water level detector to monitor the water level in real time. When the water level is lower than a preset threshold, the system will trigger an alarm to remind the user to replenish spring water and filtered water in time. This eliminates the need for the user to frequently check the water level. At the same time, it provides a reminder before the water level is too low (which may cause the equipment to dry out, water supply interruption or other problems), and ensures that the equipment has a sufficient and suitable water source to operate normally. The user only needs to respond after hearing / seeing the alarm, which improves the convenience of use and maintenance.

[0028] 2. In this invention, the teacup is preheated by the heating element, which avoids affecting the flavor of the tea soup due to the cup wall temperature being too low. After preheating, the temperature of the cup wall is close to the temperature of the tea soup, greatly reducing the temperature difference when pouring the tea soup. This effectively slows down the rate of heat transfer, reduces heat loss, and allows the tea soup to maintain an ideal drinking temperature for a longer period of time. This provides a stable thermal environment for the volatilization of aroma substances and the full dissolution of flavor substances.

[0029] 3. This invention utilizes centrifugal force generated by a stirring rod, combined with a carefully designed guide channel, to transform disordered rotating water flow into an ordered and controllable spiral water flow. By adjusting the stirring rod's rotation speed, the speed and intensity of the spiral water flow can be precisely controlled, thereby specifically meeting the different brewing dynamics requirements of oolong tea (high-speed, strong flow), black tea (medium-speed), and pu-erh tea (low-speed, slow flow). The core value of the guide channel lies in guiding the water flow to form a stable and orderly spiral path, which minimizes the direct impact and intense friction between the water flow and mechanical components on the tea leaves, achieving physical protection for the tea leaves. The ultimate goal is to obtain a tea soup with more intact form, purer flavor, and better taste. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Reference Figures 1-9A capsule tea maker includes a body 1 and a control panel 26 installed on the body 1. The control panel 26 has five buttons representing different tea brewing modes: green tea or white tea mode, oolong tea mode, black tea mode, dark tea or Pu'er tea mode, and herbal tea mode. Different modes correspond to different water temperatures and different brewing methods. The body 1 has a water storage chamber 2, which contains a temperature control component. The control component integrates a sensor, a heater, and a controller. The sensor is a commercially available product with a PT100+ infrared temperature measurement module, the heater is a commercially available product with a step-type layered heating tube, and the controller is a commercially available product with an RKC FB900+ multi-segment PID parameter group. This controls the water temperature in the water storage chamber 2. Green tea / white tea / yellow tea / some oolong teas require a lower water temperature (70-85°C). Excessively high water temperatures will scald the tender leaves, producing a bitter taste and destroying the freshness and aroma. Black tea / dark tea / ripe Pu-erh tea / some oolong teas: require relatively high water temperatures (90-95°C or close to boiling) to fully activate their internal substances and release their mellow flavor and aroma. Herbal teas: require relatively high water temperatures (90-95°C). The main body 1 has an integrally connected tea dispensing section 3. A first cover 4 is magnetically attached to the top of the water storage chamber 2, and a second cover 5 is magnetically attached to the top of the tea dispensing section 3. A water outlet is located between the first cover 4 and the second cover 5. The water outlet includes a water pump 13, a first handle 14, a water pipe 15, a second handle 16, a through hole 17, a nozzle 18, and a water outlet pipe 19. The components are configured as follows:

[0042] Water pump 13 is fixedly installed on the first cover 4. The output flow rate of water is controlled by water pump 13. For specific working process, please refer to the appendix. Figure 7 The first handle 14 is fixedly installed on the top of the first cover 4. One end of the water pipe 15 extends through the first handle 14 to the outside of the water storage chamber 2, and the other end of the water pipe 15 extends through the water pump 13 and the first cover 4 to the inside of the water storage chamber 2. The second handle 16 is fixedly installed on the top of the second cover 5. Both the first handle 14 and the second handle 16 are composed of a cylinder and a disc. The through hole 17 is opened at the center of the second handle 16. The nozzle 18 is fixedly connected to the other end of the water pipe 15, and the water outlet pipe 19 is fixedly connected to the nozzle 18. The water outlet pipe 19 is slidably fitted in the through hole 17.

[0043] A connecting pipe 24, which is connected to the water storage chamber 2, is fixedly connected to the main body 1. Other water replenishment devices (such as an external smart water tank) can be connected through the connecting pipe 24 to increase the water storage capacity of the water storage chamber 2.

[0044] A water level detector 25 is fixedly installed on the inner wall of the water storage chamber 2, and an alarm 11 electrically connected to the water level detector 25 is fixedly installed on the outer wall of the body 1. The water level detector 25 integrates a detector and a controller. The detector senses the water level status, and the controller processes the information and makes decisions. The water level detector 25 is a commercially available product with the model AXTEK ANY01 chip + AX01-GY2 module. The alarm 11 receives instructions from the controller and emits a visible, audible or remotely received warning signal when an alarm is needed. The alarm 11 is a commercially available product with the model WEIKE CA-09X.

[0045] A limiting ring 6 for carrying tea capsules is fixedly connected to the inner wall of the tea dispensing part 3. An abutment ring 27 that cooperates with the limiting ring 6 to abut and limit the tea capsule is fixedly connected to the bottom of the second cover 5. The top of the limiting ring 6 abuts and limits the bottom of the outermost edge of the tea capsule. When the second cover 5 is installed, the abutment ring 27 will move with the movement of the second cover 5, so that the abutment ring 27 abuts and limits the top of the outermost edge of the tea capsule. At this time, the limiting ring 6 and the abutment ring 27 realize the installation of the tea capsule by abutting and limiting the upper and lower sides of the outermost edge of the tea capsule. It should be noted that the inner wall of the tea dispensing part 3 and the outermost edge of the tea capsule move against each other.

[0046] The bottom of the second cover 5 is fixedly connected to a puncture needle 7, which consists of a cone and a frustum. Since the height of the frustum at the upper end is three times the height of the cone at the lower end, and the larger diameter end of the frustum at the upper end is connected to the larger diameter end of the cone at the lower end, there is a large gap between the tea capsule and the puncture needle 7 after the puncture needle 7 enters the tea capsule, so that water can flow into the tea capsule.

[0047] The bottom of the tea dispensing section 3 has a drain outlet 8, which consists of two semi-circular annular through holes. The bottom of the tea dispensing section 3 has an annular inclined slope to guide the tea soup out of the drain outlet 8. A motor 9 is fixedly connected to the bottom of the tea dispensing section 3. The specific working process of the motor 9 can be found in the appendix. Figure 8 The output end of motor 9 is fixedly connected to cylinder 10, and the output end of cylinder 10 is fixedly connected to tea extraction unit. The tea extraction unit includes tea filter plate 20, cutting blade 21, stirring rod 22 and guide groove 23. The components are arranged as follows:

[0048] The tea filter plate 20 is fixedly connected to the cylinder 10. The tea filter plate 20 has a frustum-shaped structure and is made of non-porous ceramic material. The pore size of the non-porous ceramic surface is <0.1μm, which effectively prevents the adsorption of tea polyphenols, pigments, and aroma molecules, avoiding the flavor residue and cross-contamination problems of traditional metal or gauze filters. At the same time, the chemical inertness of the non-porous ceramic blocks the catalysis of metal ions, reducing the oxidation rate of the tea soup. The surface smoothness Ra≤0.05μm prevents bacteria from attaching. Simultaneously, a high-temperature sintering manufacturing process is used to form a stable α-alumina crystal phase, with lead and cadmium leaching <0.001ppm. The tea filter plate 20 moves in contact with the inner wall of the tea outlet section 3. The cutting blade 21 is fixedly connected to the tea filter plate 20. The cutting blade 21 is a conical blade with a tapered edge that gradually thickens from the tip to the bottom, allowing the cutting force to be released in a gradient. The radial component of the cone pushes the tea leaves outwards, thus preventing the tea leaves from breaking during the operation of the cutting blade 21. The stirring rod 22 is fixedly connected to the filter plate 20. At the center of the tea plate 20, the top of the stirring rod 22 has a conical structure, and the guide grooves 23 are symmetrically opened on the stirring rod 22. The cross-section of the guide grooves 23 is an isosceles trapezoid with a wider top and a narrower bottom. The depth of the guide grooves 23 is h = 0.3D (D is the diameter of the stirring rod 22), the top width of the guide grooves 23 is W_top = 1.5h, and the bottom width of the guide grooves 23 is W_bottom = 0.7h. At the same time, the smooth slope of the guide grooves 23 reduces turbulent energy loss and improves the stability of the swirling flow. The wide-top, narrow-bottom design of the guide channel 23 effectively prevents tea leaves from getting stuck. When water flows through the guide channel 23, the channel wall applies a tangential force to the water flow, converting some of the axial kinetic energy into rotational kinetic energy and giving the water flow angular momentum. The guide channel 23 disturbs the boundary layer, breaks the symmetry of laminar flow, and guides the fluid to rotate along the direction of the guide channel 23, thereby inducing the water to generate a stable spiral flow. The rotating water flow can make the tea leaves tumble fully, which will improve the taste of oolong tea, black tea, dark tea, or pu-erh tea after brewing.

[0049] The main body 1 is located below the tea dispensing section 3 and is equipped with a heating section 12. The heating section 12 preheats the teacup, which can prevent the tea soup from being affected by the low temperature of the cup wall. After preheating, the temperature of the cup wall of the teacup is close to the temperature of the tea soup, which greatly reduces the temperature difference when pouring the tea soup.

[0050] The functional principle of this invention can be explained through the following operational methods:

[0051] Open the first cover 4 and put spring water or filtered water into the water storage chamber 2. Cover the first cover 4 to seal the water storage chamber 2. Open the second cover 5 and place the upper edge of the tea capsule on the limiting ring 6. Cover the second cover 5. The contact ring 27 moves against the top edge of the upper edge of the tea capsule. The puncturing needle 7 will puncture the top of the tea capsule, making multiple through holes appear at the top of the tea capsule. At the same time, the stirring rod 22 enters the tea capsule and inserts the water outlet pipe 19 into the through hole 17, so that the water outlet pipe 19 extends to the tea outlet 3. Start the cylinder 10 to drive the tea filter plate 20 to move vertically upward, so that the cutting blade 21 contacts the tea capsule, making multiple openings cut at the bottom of the tea capsule. Place the tea cup below the drain outlet 8 and start the heating unit 12 to raise the temperature of the tea cup.

[0052] When the tea capsule is green tea or white tea, the control panel 26 controls the water pump 13 to enter the low output mode, and the water flows slowly to the tea outlet 3, so that the green tea and white tea are brewed in a gentle direct flow. At the same time, the tea soup is discharged through the opening at the bottom of the tea capsule, so that the tea soup flows into the teacup through the drain outlet 8.

[0053] When the tea capsule containing oolong tea is used, the control panel 26 controls the motor 9 to start, and the water pump 13 uses water to flow to the tea outlet 3, which causes the motor 9 to drive the stirring rod 22 to rotate at high speed. The guide channel 23 causes the tea leaves and water to move in a spiral motion in the tea capsule, so that the oolong tea is brewed in a strong spiral water flow. At the same time, the tea soup is discharged through the opening at the bottom of the tea capsule, and the tea soup flows to the teacup through the drain outlet 8.

[0054] When the tea capsule containing black tea is used, the control panel 26 controls the motor 9 to start, and the water pump 13 uses water to flow to the tea outlet 3, so that the motor 9 drives the stirring rod 22 to rotate at a medium speed. The guide channel 23 makes the tea leaves and water flow in a spiral motion in the tea capsule, so that the black tea is brewed in a medium-speed spiral water flow. At the same time, the tea soup is discharged through the opening at the bottom of the tea capsule, and the tea soup flows to the teacup through the drain outlet 8.

[0055] When the tea capsule is filled with black tea or Pu'er tea, the control panel 26 controls the motor 9 to start, and the water pump 13 uses water to flow to the tea outlet 3, so that the motor 9 drives the stirring rod 22 to rotate at a low speed. The guide groove 23 makes the tea and water flow in a spiral motion in the tea capsule, so that the black tea or Pu'er tea is brewed in a low-speed spiral water flow. At the same time, the tea soup is discharged through the opening at the bottom of the tea capsule, and the tea soup flows into the teacup through the drain outlet 8.

[0056] When the tea capsule is herbal tea, the control panel 26 controls the water pump 13 to enter the normal output mode, and the water flows to the tea outlet 3, so that the herbal tea is brewed in a direct current. At the same time, the tea soup is discharged through the opening at the bottom of the tea capsule, so that the tea soup flows to the teacup through the drain outlet 8.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
