Description

Technical Field

[0001] The invention relates to the technical field of tea making machines, in particular to a capsule tea making machine. Background Art

[0002] Tea capsules are a new form of tea brewing that encapsulates pre-processed tea leaves in capsules. Its core advantage is that it is easy to operate and saves time and energy. The tea brewed with tea capsules can still maintain high quality, so it is deeply favored by consumers.

[0003] However, in traditional tea brewing machines, the brewing mechanism pierces the upper and lower surfaces of the tea capsule, and a water pipe is set inside the piercing device. Water flows unidirectionally from top to bottom into the capsule to extract tea leaves. This unidirectional water flow brewing method affects the final taste and flavor characteristics of oolong tea, Pu'er tea, and other teas that require specific brewing conditions to fully release the substances contained in them, and it is difficult to fully meet consumers' pursuit of the best taste experience. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the single-direction water flow brewing method in the prior art cannot meet the brewing conditions of oolong tea, Pu'er tea, etc., and to propose a capsule tea brewing machine.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A capsule tea making machine comprises a body and a control panel installed on the body, the body is provided with a water storage chamber, a tea outlet portion is integrally connected to the body, a first cover body is magnetically installed on the top of the water storage chamber, a second cover body is magnetically installed on the top of the tea outlet portion, a water outlet portion is arranged between the first cover body and the second cover body, a limiting ring for carrying tea capsules is fixedly connected to the inner wall of the tea outlet portion, a puncturing needle is fixedly connected to the bottom end of the second cover body, a drain outlet is provided at the bottom end of the tea outlet portion, a motor is fixedly connected to the bottom end of the tea outlet portion, a cylinder is fixedly connected to the output end of the motor, a tea extraction portion is fixedly connected to the output end of the cylinder, and a heating portion is arranged correspondingly to the position of the body below the tea outlet portion.

[0006] Preferably, a resistance ring is fixedly connected to the bottom end of the second cover body and cooperates with the limiting ring to limit the tea capsule.

[0007] Preferably, the water outlet portion comprises: a water pump, the water pump being fixedly mounted on the first cover; A first handle, wherein the first handle is fixedly disposed on the top of the first cover body; a water pipe, one end of which extends to the outside of the water storage cavity through the first handle, and the other end of which extends to the inside of the water storage cavity through the water pump and the first cover; A second handle, which is fixedly arranged at the top of the second cover body; A through hole, which is opened at the center of the second handle; A nozzle, which is fixedly connected to the other end of the water pipe; A water outlet pipe, which is fixedly connected to the nozzle, and the connecting pipe is slidably fitted in the through hole.

[0008] Preferably, both the first handle and the second handle are composed of a cylinder and a disc.

[0009] Preferably, a connecting pipe communicating with the water storage cavity is fixedly connected to the machine body, a water level detector is fixedly installed on the inner wall of the water storage cavity, and an alarm electrically connected to the water level detector is fixedly installed on the outer wall of the machine body.

[0010] Preferably, the puncturing needle is composed of a cone and a frustum of a cone, and the height value of the frustum of the cone at the upper end is three times the height value of the cone at the lower end.

[0011] Preferably, the drain port is composed of two semi-circular ring-shaped through holes, and the bottom end of the tea outlet part is an annular inclined slope.

[0012] Preferably, the tea extraction part includes: A tea filter plate, which is fixedly connected to the cylinder, and the tea filter plate is in movable contact with the inner wall of the tea outlet part; A cutting blade, which is fixedly connected to the tea filter plate; A stirring rod, which is fixedly connected to the center of the tea filter plate; Flow guiding grooves, which are symmetrically opened on the stirring rod.

[0013] Preferably, the tea filter plate is in the shape of a frustum of a cone, the top end of the stirring rod is in the shape of a cone, and the cross section of the flow guiding groove is an isosceles trapezoid with a wider upper part and a narrower lower part.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention is equipped with a water level detector to monitor the water level state in real time. When the water level is lower than the preset threshold, the system will trigger the alarm to send an alarm, so as to prompt the user to supplement mountain spring water and filtered water in time, enabling the user not to frequently check the water level. At the same time, a reminder is sent before the water level is too low (which may cause problems such as dry burning of the device, interruption of water supply, or other issues), and it is ensured that the device has sufficient and appropriate water sources to continuously operate normally. The user only needs to respond after hearing / seeing the alarm, which improves the convenience of use and maintenance.

[0015] 2. In the present invention, the teacup is pre-heated by the heating part, which can avoid affecting the flavor of the tea soup due to too low temperature of the cup wall. For the pre-heated teacup, the temperature of its 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 heat transfer speed, reduces heat loss, and enables the tea soup to maintain an ideal drinking temperature for a longer time. This provides a stable thermal environment for the volatilization of aroma substances and the full dissolution of taste substances.

[0016] 3. In the present invention, the stirring rod generates centrifugal force, and combined with the carefully designed diversion groove, the disordered rotating water flow is transformed into an orderly and controllable spiral water flow. By adjusting the rotation speed of the stirring rod, the speed and intensity of the spiral water flow can be precisely controlled, so as to specifically meet the different brewing kinetic requirements of oolong tea (high speed and strong flow), black tea (medium speed and moderate), and pu-erh tea (low speed and slow flow). The core value of the diversion groove lies in guiding the water flow to form a stable and orderly spiral path, which maximally avoids the direct impact and intense friction of the water flow and mechanical components on the tea leaves, realizes the physical protection of the tea leaves, and the ultimate goal is to obtain a tea soup with a more complete form, purer flavor, and better taste.

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-9 , a capsule tea brewing machine, including a body 1 and a control panel 26 installed on the body 1. There are five buttons representing different tea brewing modes on the control panel 26, namely green tea or white tea mode, oolong tea mode, black tea mode, dark tea or pu-erh tea mode, and herbal tea mode. Different modes correspond to different water temperatures and different brewing methods. A water storage cavity 2 is opened on the body 1, and a temperature control component is arranged in the water storage cavity 2. The control component integrates a sensor, a heater and a controller. The sensor selects a commercially available product with a model of PT100 + infrared temperature measurement module, the heater selects a commercially available product with a model of step-by-step stratified heating pipe, and the controller selects a commercially available product with a model of RKC FB900 + multi-segment PID parameter group to control the water temperature in the water storage cavity 2. Green tea / white tea / yellow tea / part of oolong tea: requires a lower water temperature (70 - 85 °C). Too high a water temperature will scald the tender leaves, produce a bitter taste, and destroy the freshness and fragrance. Black tea / dark tea / pu-erh ripe tea / part of oolong tea: requires a higher water temperature (90 - 95 °C or close to boiling). Only high temperature can fully stimulate its internal substances and release a mellow taste and aroma. Herbal tea: requires a higher water temperature (90 - 95 °C). A tea outlet part 3 is integrally connected to the body 1. A first cover body 4 is magnetically installed at the top of the water storage cavity 2, and a second cover body 5 is magnetically installed at the top of the tea outlet part 3. An outlet part is arranged between the first cover body 4 and the second cover body 5. The outlet part 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 settings of each component are as follows: The water pump 13 is fixedly installed on the first cover body 4 to control the output flow of water by using the water pump 13. The specific working process can be referred to in the appendix Figure 7The first handle 14 is fixedly arranged on the top of the first cover body 4, one end of the water pipe 15 extends to the outside of the water storage chamber 2 through the first handle 14, and the other end of the water pipe 15 extends to the water storage chamber 2 through the water pump 13 and the first cover body 4. The second handle 16 is fixedly arranged on the top position of the second cover body 5. The first handle 14 and the second handle 16 are both composed of a cylinder and a disc. The through hole 17 is opened at the center position 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, and the water outlet pipe 19 is slidably fitted in the through hole 17.

[0021] A connecting pipe 24 communicating with the water storage chamber 2 is fixedly connected to the body 1 , and other water replenishment equipment (such as an external intelligent water tank) can be connected through the connecting pipe 24 to increase the water storage capacity of the water storage chamber 2 .

[0022] 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 is used to sense the water level state, and the controller is used to process information and make decisions. The water level detector 25 uses a commercially available product with model AXTEK ANY01 chip + AX01-GY2 module. The alarm 11 receives instructions from the controller and sends out a visible, audible or remotely receivable warning signal when an alarm is required. The alarm 11 uses a commercially available product with model WEIKE CA-09X.

[0023] A limiting ring 6 for carrying tea capsules is fixedly connected to the inner wall of the tea outlet portion 3, and a resistance ring 27 for cooperating with the limiting ring 6 to limit the tea capsule is fixedly connected to the bottom end of the second cover body 5. The top of the limiting ring 6 is in contact with the bottom end of the outermost edge of the tea capsule. When the second cover body 5 completes the installation operation, the resistance ring 27 will move with the movement of the second cover body 5, so that the resistance ring 27 is in contact with the top end of the outermost edge of the tea capsule. At this time, the limiting ring 6 and the resistance ring 27 realize the installation of the tea capsule by the resistance limiting on the upper and lower sides of the outermost edge of the tea capsule. It should be noted that the inner wall of the tea outlet portion 3 and the outermost edge of the tea capsule are movably in contact with each other.

[0024] A puncturing needle 7 is fixedly connected to the bottom end of the second cover body 5. The puncturing needle 7 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 end with a larger diameter of the frustum at the upper end is connected to the end with a larger diameter of the cone at the lower end, after the puncturing needle 7 enters the tea capsule, a large gap exists between the tea capsule and the puncturing needle 7 to facilitate water to flow into the tea capsule.

[0025] The bottom of the tea outlet 3 is provided with a drain port 8, which is composed of two semicircular through holes. The bottom of the tea outlet 3 is a circular inclined slope, so as to guide the tea soup to be discharged from the drain port 8. The bottom of the tea outlet 3 is fixedly connected with a motor 9. The specific working process of the motor 9 can be referred to in the attached Figure 8 The output end of the motor 9 is fixedly connected to the cylinder 10, and the output end of the cylinder 10 is fixedly connected to the tea extraction unit, which includes a tea filter plate 20, a cutting blade 21, a stirring rod 22 and a guide groove 23. The components are arranged as follows: The tea filter plate 20 is fixedly connected to the cylinder 10. The tea filter plate 20 is a truncated cone structure. The tea filter plate 20 is made of non-porous ceramic material. The pore size of the non-porous ceramic surface is less than 0.1μm, which effectively prevents the adsorption of tea polyphenols, pigments, and aroma molecules, and avoids the problem of flavor residue and cross-flavor of traditional metal filters or gauze filters. At the same time, the chemical inertness of non-porous ceramics is used to block metal ion catalysis, so that the oxidation rate of tea soup is reduced. The surface finish Ra is ≤0.05μm, and bacteria have nowhere to attach. At the same time, a high-temperature sintering manufacturing process is used to form a stable α-alumina crystal phase, and the lead and cadmium dissolution amount is less than 0.001ppm. The tea filter plate 20 is in active contact with the inner wall of the tea outlet 3. The cutting blade 21 is fixedly connected to the tea filter plate 20. The cutting blade 21 is a conical blade. The conical edge gradually thickens from the tip to the bottom, so that the cutting force is released in a gradient. The radial force of the cone pushes the tea leaves to the surroundings, thereby preventing the tea leaves from being broken when the cutting blade 21 is working. 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 is a conical structure, the guide groove 23 is symmetrically opened on the stirring rod 22, the cross section of the guide groove 23 is an isosceles trapezoid that is wide at the top and narrow at the bottom, the depth of the guide groove 23 is h=0.3D (D is the diameter of the stirring rod 22), the top width of the guide groove 23 is W_top=1.5h, the bottom width of the guide groove 23 is W_bottom=0.7h, and the smooth slope of the guide groove 23 reduces the turbulent energy loss, so that the swirl stability is improved. The wide top and narrow bottom design of the guide groove 23 effectively prevents tea leaves from getting stuck. When water flows through the guide groove 23, the groove wall exerts a tangential force on the water flow, converting part of the axial kinetic energy into rotational kinetic energy, giving the water flow angular momentum. The guide groove 23 disturbs the boundary layer, breaks the symmetry of the laminar flow, and guides the fluid to rotate along the direction of the guide groove 23, thereby inducing the water to produce a stable spiral flow. The rotating water flow can make the tea leaves roll fully, so that the taste of oolong tea, black tea, dark tea or Pu'er tea after brewing will be improved.

[0026] The machine body 1 is provided with a heating unit 12 corresponding to the position below the tea dispensing unit 3. The heating unit 12 can preheat the tea cup to avoid affecting the flavor of the tea soup due to the excessively low temperature of the cup wall. The wall temperature of the preheated tea cup is close to the temperature of the tea soup, which greatly reduces the temperature difference when pouring the tea soup.

[0027] The present invention can be explained by the following operation mode: Open the first cover 4, put spring water or filtered water into the water storage chamber 2, cover the first cover 4 to close the water storage chamber 2, open the second cover 5, place the upper edge of the tea capsule on the limit ring 6, cover the second cover 5, the abutment ring 27 movably abuts against the top of the upper edge of the tea capsule, the piercing needle 7 pierces the top of the tea capsule, so that a plurality of through holes appear on the top of the tea capsule, and at the same time the stirring rod 22 enters the tea capsule, inserts the water outlet pipe 19 into the through hole 17, so that the water outlet pipe 19 extends to the tea outlet part 3, starts the cylinder 10 to drive the tea filter plate 20 to move vertically upward, so that the cutting blade 21 comes into contact with the tea capsule, so that a plurality of openings are cut at the bottom of the tea capsule, and the tea cup is placed below the drain port 8, and the heating part 12 is started to increase the temperature of the tea cup; When the tea capsules placed are 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 and direct manner, and the tea soup is discharged through the opening at the bottom of the tea capsule, so that the tea soup flows into the tea cup through the drain port 8; When the tea capsule put in is oolong tea, the control panel 26 controls the motor 9 to start, and uses the water pump 13 to flow water to the tea outlet 3, so that the motor 9 drives the stirring rod 22 to rotate at a high speed, and uses the guide groove 23 to make the tea leaves and the water flow to spirally move in the tea capsule, so that the oolong tea is brewed in the form of a strong spiral water flow, and 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 tea cup through the drain port 8; When the tea capsule put in is black tea, the control panel 26 controls the motor 9 to start, and uses the water pump 13 to flow water to the tea outlet 3, so that the motor 9 drives the stirring rod 22 to rotate at a medium speed, and uses the guide groove 23 to make the tea leaves and the water flow to spirally move in the tea capsule, so that the black tea is brewed in the form of a medium-speed spiral water flow, and 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 tea cup through the drain port 8; When the tea capsules put in are black tea or Pu'er tea, the control panel 26 controls the motor 9 to start, and the water pump 13 is used to make the water flow to the tea outlet 3, so that the motor 9 drives the stirring rod 22 to rotate at a low speed, and the guide groove 23 is used to make the tea leaves and the water flow to spirally move in the tea capsule, so that the black tea or Pu'er tea is brewed in the form of a low-speed spiral water flow, and 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 tea cup through the drain port 8; When the inserted 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 manner. 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 tea cup through the drain port 8.
