Description

Technical Field

[0001] This invention relates to the field of tea brewing machine technology, and more particularly to a rising and rotating device for dispensing tea in a tea brewing machine. Background Technology

[0002] In tea culture, appreciating the flavor changes of the same tea leaves at different infusions (such as the richness of the first infusion, the mellowness of the second, and the sweet aftertaste of the third) is a core pleasure and a professional standard of evaluation. Traditional Gongfu tea ceremony uses a "fairness cup" to distribute the tea, aiming to ensure that the concentration of the tea soup in the same infusion is uniform. However, mixing tea soup from different infusions actually eliminates this vertical flavor gradient.

[0003] Most automatic tea makers on the market today focus on simulating and simplifying the process of "single brewing - even distribution of tea". For example, 1) Chinese patent document CN201711266173.8 discloses a multi-functional automatic tea maker that can dispense tea and its method of use, including a machine body. The machine body is characterized in that a tea brewing box and a water storage box are respectively arranged on the front and rear sides of the upper part of the machine body. The bottom of the tea brewing box is provided with a water outlet that extends out of the machine body. The upper part of the tea brewing box is provided with a tea box that extends into the tea brewing box for placing tea leaves and can be pulled out and closed. The lower part of the machine body and below the water outlet is provided with a teacup holder. The teacup holder is provided with a wastewater tank and a strip hole for inserting the wastewater tank is provided on the surface of the teacup holder. A rotating tea tray that is detachably connected to the teacup holder is provided on the front side of the teacup holder. The rotating tea tray includes a tea tray shell. A drainage storage chamber is located at the top of the tea tray shell, and a drainage hole is located at the rear of the drainage storage chamber for draining water into the teacup holder surface. A rotating teacup holder, rotatable around the central axis of the tea tray shell, is located above the tea tray shell, and several teacup placement rings are evenly distributed on the rotating teacup holder. A concave hole for inserting the teacup holder is located at the rear of the tea tray shell. Square holes are located on both sides of the concave hole, and a movable swing block is located within each square hole. One end of the movable swing block is hinged to the square hole and is equipped with a torsion spring for swinging the other end of the movable swing block into the concave hole. A base is located below the tea tray housing, and a motor is fixed on the base. A small bevel gear is located at the output end of the motor, meshing with a large bevel gear. The large bevel gear is connected to a worm gear fixed on a bearing seat. A rotating shaft passing through the tea tray housing is vertically arranged at the lower part of the rotating teacup holder, and a turbine cooperating with the worm gear is located at the lower end of the shaft. An angle control disc rotating with the turbine is located below the turbine. Spherical protrusions corresponding to the number of teacup placement rings are spaced around the periphery of the angle control disc. An angle control switch is located on the base next to the angle control disc. An electronic control unit for controlling the motor and angle control switch is also located on the base. The electronic control unit has a communication interface extending from the rear of the tea tray housing, which is used to connect to a teacup holder interface located on the front of the teacup holder. The water tank is equipped with a lid at its upper end. A heater and temperature sensor are installed inside the water tank. The lower part of the water tank is connected to a tea brewing tank via a pipe containing a water pump. The tea brewing tank is equipped with a lid at its upper end. A control panel is also installed on the external side wall of the machine body. The heater, temperature sensor, and water pump are connected to the control panel via an electronic control unit located inside the machine body. A first two-position three-way solenoid valve is installed below the water tank. The rear interface of the first two-position three-way solenoid valve is connected to the first solenoid water outlet valve at the lower part of the water tank. The upper interface of the first two-position three-way solenoid valve is connected to the input end of the water pump. The output end of the water pump is connected to the upper part of the tea brewing tank.The machine body has a three-position three-way solenoid valve located below the tea brewing box. The upper interface of the three-position three-way solenoid valve is connected to the bottom of the tea brewing box. The front interface of the lower end of the three-position three-way solenoid valve is connected to the water outlet. The rear interface of the lower end of the three-position three-way solenoid valve is connected to the upper interface of the second two-position three-way solenoid valve. The rear interface of the second two-position three-way solenoid valve is connected to the front interface of the first two-position three-way solenoid valve. The lower interface of the second two-position three-way solenoid valve is the wastewater drain outlet. The first two-position three-way solenoid valve, the second two-position three-way solenoid valve, and the three-position three-way solenoid valve are respectively connected to the electronic control unit. A method for using a multifunctional automatic tea brewing machine capable of dispensing tea, characterized by the following steps: (1) connecting the rotating tea tray to the teacup holder and placing a teacup on the teacup placement ring of the rotating tea tray; (2) removing the tea box, adding an appropriate amount of tea, and then pushing the tea box back into the brewing chamber; (3) pouring an appropriate amount of water into the water tank and covering the water tank lid; (4) pressing the button on the control panel located on the external side wall of the machine body, wherein the control panel is connected to the electronic control unit located inside the machine body for controlling the heater, temperature sensor, and pipeline connected to the water tank in the water tank. The water pump and outlet are activated simultaneously. Press the control button located in front of the rotating tea tray to select the number of teacups and the capacity of each cup. The tea brewing program will then begin. (5) The electronic control unit, in conjunction with the electronic control unit of the rotating tea tray, calculates the water output of the outlet based on the set capacity of each cup. After brewing one cup of tea, the electronic control unit controls the outlet to stop dispensing tea. (6) After brewing the first cup of tea, the electronic control unit controls the rotating teacup holder to rotate 60° and places the next empty cup below the outlet. Repeat step (5) to complete the brewing of the second cup of tea. This process continues until all teacups are brewed, thus completing the tea distribution process. 2) Chinese patent document CN201610543690.4 discloses a tea brewing machine, which includes: a base, a water tank, a water pump, a heating device, a tea brewing cup, a tea receiving cup, and a control device. The water pump and the heating device are electrically connected to the control device.

The control device is electrically connected to the first solenoid valve and the second solenoid valve respectively. The control device selectively activates either the first solenoid valve or the second solenoid valve. The water tank supplies water to the electrolytic cell, and the electrolytic cell is connected to the water pump through the first solenoid valve or the second solenoid valve. The water pump is connected to the heating device and the tea brewing cup in sequence.3) Chinese patent document CN202420490845.2 discloses a tea-dispensing driving device for a tea maker, including a support frame, a swinging component and a driving assembly mounted on the support frame. The swinging component is rotatably mounted on the support frame via a connecting shaft. The driving assembly includes a lifting seat, a screw, and a rotary motor. The lifting seat is slidably connected to the support frame and abuts against a first swing arm on the swinging component. The screw is threadedly connected to the lifting seat. The rotary motor can drive the lifting seat to move up and down via the screw, so that the lifting seat can press the first swing arm on the swinging component to rotate downwards and cause the second swing arm on the swinging component to rotate upwards to press against the water outlet valve on the tea maker. This invention adopts a screw structure. The rotary motor drives the swinging component to rotate through the cooperation of the screw and the lifting seat to open the water outlet valve, so that the impact force of the swinging component on the water outlet valve is small. At the same time, the screw and the lifting seat have a locking function to prevent the lifting seat from moving up and down freely and to turn off the rotary motor to reduce energy consumption.

[0004] Specifically, existing technologies have the following inherent drawbacks:

[0005] 1. Flavor confusion: Continuously pouring tea liquor from multiple infusions into the same fairness cup causes tea liquor from different infusions and with different flavors to mix together, destroying the tea's inherent layers of flavor and failing to meet the needs of tasting, comparing, or selecting one's favorite infusion.

[0006] 2. Inhumane Process: If users wish to savor the unique flavor of each brew, they must manually replace or label the different fairness cups or tasting cups after each brew. This forces users, who are focused on conversation or observation, to frequently interrupt their work, making the automated equipment "non-automatic."

[0007] 3. Lack of tasting support: The design philosophy of existing equipment remains focused on "quenching thirst" or "convenience," rather than "tasting." It cannot provide tea enthusiasts, tea judges, or ordinary consumers with an intuitive and orderly A / B (or multiple infusions) comparative experience.

[0008] Therefore, the industry urgently needs a revolutionary automatic tea brewing device whose core task is no longer simply "uniformly dispensing the tea," but rather upgrading to "the separation and presentation of flavor." This device should be able to automatically and accurately dispense each unique brew of tea independently, making it an independent sample for users to taste in parallel. This elevates automation technology from merely replacing manual labor to a new level that enhances sensory experience and cultural connotation. Summary of the Invention

[0009] The purpose of this invention is to provide a tea brewing machine with a rising and rotating device for dispensing tea, which can completely output the tea soup from each brewing into the corresponding fairness cup, in order to solve the problems mentioned in the background art.

[0010] To solve, or at least partially solve, the above-mentioned technical problems, the present invention provides a lifting and rotating device for dispensing tea in a tea brewing machine. The lifting and rotating device for dispensing tea in a tea brewing machine includes: a lifting drive mechanism for a tea-pouring cup and a water-blocking device of a tea-brewing container; the tea-pouring cup includes a tea outlet; the lifting drive mechanism includes a reduction motor; the lifting drive mechanism further includes a reduction gear, a functional gear, a driven gear, and a steering gear; the tea-pouring cup is also provided with a conical top for lifting the water-blocking device of the tea-brewing container; a steering positioning block is connected to the bottom of the tea-pouring cup; the steering positioning block has a groove; the steering gear has a buckle plate with its upper end being a latch; the buckle plate extends into the groove of the steering positioning block; when the steering positioning block moves upward, its groove can fit over the buckle plate without detaching from it; a spring-loaded ejector has its upper end passing through a cylindrical cavity provided under the steering gear and an opening at the center of the steering gear, and can then press against the bottom of the steering positioning block; the reduction motor is connected to the reduction gear, the reduction gear meshes with the functional gear, and the functional gear has a frustum; the frustum... The platform has two or more arc-shaped protrusions. A driven gear is located on the truncated cone on the functional gear. The driven gear meshes with the steering gear. The lower end of the ejector is placed on the truncated cone. The rotation of the functional gear causes the arc-shaped protrusions on it to rotate, which in turn drives the lower end of the ejector to rotate up and down with the truncated cone and the arc-shaped protrusions on it. The arc-shaped protrusions are used to raise or lower the ejector. The upward movement of the ejector causes the steering positioning block to move upward, which in turn moves the conical top of the tea cup to its position and lifts the water-blocking device of the tea brewing container. This allows the tea in the tea brewing container to flow out from the outlet and into the tilted boat-shaped tea cup. From the tea outlet, through the tea guide pipe or guide groove, and the tea guide pipe spout, the tea flows into the fairness cup located below the tea guide pipe spout. At the same time, the rotation of the functional gear causes the driven gear to drive the steering gear to rotate. The rotation of the steering gear, through the engagement of the buckle plate and the groove of the steering positioning block, drives the steering positioning block and the tea cup connected to it to rotate.

[0011] Furthermore, the teacup is an inclined boat-shaped teacup with a low front end and a high rear end. The inclined boat-shaped teacup has a cabin body and a tea outlet is provided at the lower front end of the cabin body. The rear part of the cabin body of the inclined boat-shaped teacup has a pointed top that protrudes from the conical top of the cabin body.

[0012] Furthermore, the upper part of the steering gear is provided with at least two buckle plates with snap-fit ​​ends. The buckle plates extend into the groove adjacent to and above the guide groove through the guide groove provided at the bottom of the steering positioning block, which is matched in size and shape to the buckle plates. When the steering positioning block moves upward, the buckle plates can hook onto the step formed between the groove and the guide groove in the steering positioning block, so that the steering positioning block does not detach from the buckle plates.

[0013] Furthermore, a cylindrical cavity is provided below the steering gear, the upper end of the ejector is a spherical body, the lower end of the spherical body is connected to a prism, and the lower end of the ejector is an arc-shaped protrusion; the prism of the ejector is covered with a spring, and its upper end passes through the cylindrical cavity provided below the steering gear, the opening in the center of the steering gear, and the cylindrical cavity on the base before hitting the bottom of the steering positioning block.

[0014] Furthermore, the upper end of the ejector is a spherical body, and a prism is connected to the lower end of the spherical body. The lower end of the ejector is an arc-shaped protrusion. A cylinder or barrel with a curved surface on one side and connected to the prism is provided on the lower part of the prism of the ejector. An annular limiting wall is provided on the frustum located on the functional gear. The curved surface on one side of the cylinder or barrel at the lower part of the ejector rests against the annular limiting wall provided on the frustum of the functional gear. At this time, the driven gear is located on the annular limiting wall.

[0015] Furthermore, contacts are distributed below the functional gear, and a micro switch is located below the functional gear that can contact the contacts. The micro switch is connected to the geared motor through the power supply. When the functional gear rotates, the contacts below the functional gear contact the micro switch. At this time, the micro switch disconnects the power supply to the geared motor, causing the geared motor to stop rotating, allowing the tea in the tea brewing container to flow out from the outlet for a certain period of time, eventually achieving complete outflow.

[0016] Furthermore, a reversing arm is provided on the functional gear, and a trigger switch is located on the side of the functional gear. The trigger switch is connected to the geared motor via a power source. When the tea soup from the first brewing in the tea brewing container is output to the first fairness cup, the tea soup from the second brewing is output to the second fairness cup, and so on, after the final number of brewing is completed, the trigger switch touches the reversing arm on the functional gear. The trigger switch is activated, causing the geared motor to reverse, the functional gear to rotate, and the tilted boat-shaped tea cup returns to the starting position, ready for the next brewing of new tea.

[0017] Furthermore, the contacts distributed below the functional gears are positioned corresponding to the positions of the arc-shaped bosses.

[0018] Compared with the prior art, the above-mentioned technical solution provided by the present invention has the following advantages: The present invention uses multiple fairness cups, and then outputs the tea soup of each brewing into the corresponding fairness cup, that is, the tea soup of the first brewing is output into the first fairness cup, the tea soup of the second brewing is output into the second fairness cup, and so on, so that the tea soup of different brewing times and different flavors will not mix with each other, allowing users to taste the flavor of the tea soup of each brewing, experience the layering of the tea itself, and thus meet the needs of tasting, comparing or selecting the number of brewing times that they like best.

[0042] Example 1

[0043] As shown in the attached figures, this embodiment of the invention provides a lifting and rotating device (also known as a tea dispensing cup dispenser) for dispensing tea in a tea brewing machine. It includes: a tea cup 1 and a water-blocking device for the tea brewing container (such as the water outlet valve disclosed in Chinese patent document CN202420490845.2) with a lifting drive mechanism. The tea cup includes a tea outlet 2. The lifting drive mechanism includes a reduction motor 3 (a reduction motor is an integrated unit composed of a reducer and a motor, also known as a gear motor). Its structural features include a reduction gear 4, a functional gear 5, a driven gear 6, and a steering gear 7. The tea cup 1 is an inclined, boat-shaped tea cup with a low front end and a high rear end. The inclined boat-shaped tea cup has a cabin body, and the tea outlet 2 is located below the front end of the cabin body. The inclined boat-shaped tea infuser has a conical top 8 at the rear of its cabin, with its pointed tip protruding from the cabin. The conical top is used to lift the water-blocking device of the tea brewing container, which blocks the bottom outlet of the tea brewing container 19. When the inclined boat-shaped tea infuser and its connected conical top rise, they can lift the water-blocking device of the tea brewing container (such as the water outlet valve disclosed in Chinese patent document CN202420490845.2), allowing the tea in the tea brewing container 19 to flow out from the outlet and into the inclined boat-shaped tea infuser. From its tea outlet 2, it flows through the tea guide pipe or guide channel and the tea guide pipe spout into the fairness cup 9 located below the tea guide pipe spout. The bottom of the inclined boat-shaped tea infuser has a steering positioning block groove 10 with an arc transition at the rear end. The steering positioning block 11 can be positioned... Inside, the steering positioning block 11 has two grooves 11-1. The steering gear 7 has a base with a cylindrical cavity (or prismatic cavity) at its bottom. The base also has a vertical plate 7-3 and two latching plates 7-1. The upper end of the latching plates is a snap fastener, preferably an inclined snap fastener, to prevent incorrect orientation when the steering positioning block is installed. Two or more latching plates (preferably two or three equally distributed) with snap fasteners at their upper ends are provided on the upper part of the steering gear. They extend into the grooves 11-1 adjacent to and above the guide grooves through guide grooves provided on the bottom of the steering positioning block 11 that match the size and shape of the latching plates. When the steering positioning block moves up and down, its grooves can move around the latching plates without detaching from them. At this time, the cross-sectional area of ​​the groove is larger than the cross-sectional area of ​​the guide groove. The large volume of the buckle is due to the fact that the buckle at the upper end of the buckle plate is an inclined buckle. After the inclined buckle is inserted into the groove of the steering positioning block through the guide groove, it is not easy to get out of the groove (when the steering positioning block moves upward, the inclined buckle will hook on the step formed between the groove and the guide groove and is not easy to get out of the groove). The steering gear 7 is provided with a cylindrical cavity 7-2 (preferably a cylindrical cavity or a prismatic cavity) below. The cylindrical cavity, the opening through the center of the steering gear, and the base of the cylindrical cavity provided on the steering gear can communicate with each other. Preferably, the vertical plate 7-3 on the base (cylindrical) extends into the guide groove 11-2 opened on the bottom surface of the steering positioning block 11. Due to the action of the vertical plate on the base, the steering positioning block and the connected teacup are not easy to swing when moving upward.The upper end of the ejector 12 is a spherical body 12-1, with a prism 12-2 connected to the lower end of the spherical body. The lower end of the ejector is an arc-shaped protrusion 12-3. The ejector is fitted with a spring 13, and its upper end passes through the cylindrical cavity 7-2 provided under the steering gear 7, the opening at the center of the steering gear, and the cylindrical cavity on the base before pressing against the bottom of the steering positioning block 11. The prism on the upper part of the ejector 12 is fitted with a spring 13 and extends into the cylindrical cavity 7-2 provided under the steering gear and the cylindrical cavity provided on the steering gear. Its spherical body can press against the bottom surface of the steering positioning block 11 provided on the steering gear 7. The steering gear 7 can drive the steering positioning block 11 and the tilted boat-shaped teacup 1 to rotate. The spherical body at the upper end of the ejector can press against the steering positioning block to make it rotate. The upward movement causes the tilted boat-shaped teacup and its conical top 8 to rise, lifting the water-blocking device of the tea brewing container. This allows the tea in the tea brewing container to flow out from the outlet into the tilted boat-shaped teacup, and then from its outlet 2 through the tea guide pipe or guide channel and the tea guide pipe spout into the fairness cup 9 located below the tea guide pipe spout. The reduction motor 3 is connected to the reduction gear 4, which meshes with the functional gear 5. The rotation of the reduction motor drives the reduction gear to rotate, which in turn drives the functional gear to rotate. The reduction gear can be a multi-stage gear system (single or more stages). A frustum 5 is provided on the functional gear 5. 1. Two or more arc-shaped bosses 5-2 are distributed on the frustum surface, generally evenly distributed. The arc-shaped protrusion 12-3 at the lower end of the ejector 12 rests on the frustum surface of the frustum 5-1. The rotation of the functional gear 5 causes the arc-shaped bosses 5-2 on it to rotate, driving the arc-shaped protrusion 12-3 at the lower end of the ejector to move up and down with the rotation of the frustum surface and the arc-shaped bosses 5-2 on it. At this time, the arc-shaped bosses 5-2 are used to raise or lower the ejector 12. A driven gear 6 is provided on the frustum located on the functional gear 5. The driven gear 6 meshes with the steering gear 7. The number of teeth of the driven gear is much smaller than the number of teeth of the steering gear. Its tooth ratio and module are achievable by general technicians. The rotation of the driven gear drives the steering gear to rotate very slowly. 5. Rotation causes the driven gear 6, which rotates synchronously, to rotate. The rotation of the driven gear drives the steering gear 7 to rotate very slowly. At this time, the tea outlet 2 of the tilted boat-shaped tea cup can still be aligned with the tea guide pipe or guide channel when the steering gear rotates. At this time, the inlet of the tea guide pipe or guide channel has a certain size and cannot be too small. Otherwise, the tea outlet of the tilted boat-shaped tea cup will not be aligned with the tea guide pipe or guide channel after rotation. Alternatively, the arc-shaped protrusion at the lower end of the ejector can be set to rotate with the arc-shaped boss and rise from one side of the arc-shaped boss along the uphill arc surface of the arc-shaped boss (at this time, the conical top does not lift the water blocking device of the tea brewing container when it rises). Only when the arc-shaped protrusion at the lower end of the ejector reaches the arc top of the arc-shaped boss and the conical top rises will it lift the water blocking device of the tea brewing container.When the functional gear rotates, causing its arc-shaped boss to rotate, it drives the arc-shaped protrusion at the lower end of the ejector to move up and down along with the rotation of the frustum surface and its arc-shaped boss. That is, the arc-shaped protrusion at the lower end of the ejector rotates with the arc-shaped boss, rising from one side of the arc-shaped boss along its uphill arc surface, reaching the apex, and then descending along its downhill arc surface. At this time, as the arc-shaped protrusion at the lower end of the ejector rises, the spherical body at the upper end of the ejector can press against the steering positioning block, causing it to move upwards. The steering positioning block then moves upwards. The tilted boat-shaped teacup and its conical top move upwards together, causing the tilted boat-shaped teacup and its connected conical top to rise into position, thus lifting the water-blocking device of the tea brewing container. This allows the tea in the tea brewing container to flow out from the outlet into the tilted boat-shaped teacup, and from its outlet, through the first tea guide pipe or guide channel, and the first tea guide pipe spout, into the first fairness cup located below the first tea guide pipe spout; the lower end of the ejector... As the arc-shaped protrusion rotates, it rises along the uphill arc surface of the arc-shaped protrusion from one side, and then descends along the downhill arc surface after reaching the top. When the ejector is lowered by the spring's return force, the conical top of the tilted boat-shaped teacup moves downwards under gravity. The water-blocking device of the tea brewing container also moves downwards, gradually blocking the water outlet of the tea brewing container until it is finally closed. During this rising and falling process, all the tea in the tea brewing container flows out into the fairness cup, simultaneously fulfilling its function. The rotation of the gear causes the driven gear to drive the steering gear to rotate very slowly. The rotation of the steering gear causes the steering positioning block and the tea cup connected to it to rotate very slowly. At this time, the tea outlet of the tilted boat-shaped tea cup can still be aligned with the first tea guide tube or guide channel. Therefore, the inlet of the first tea guide tube or guide channel is larger than the tea outlet of the boat-shaped tea cup. In this way, the inlet of the first tea guide tube or guide channel can completely catch the tea flowing out of the tea outlet of the boat-shaped tea cup, thus completing one brew. As the functional gear rotates for a sufficient period of time, the tilted boat-shaped tea infuser also rotates to the required angle, aligning with the second tea guide pipe or channel. The spout of the second tea guide pipe or channel aligns with the second fairness cup located below the spout. At this point, the tea in the brewing container has completed its second infusion. The functional gear then causes the arc-shaped protrusion at the lower end of the ejector to move upward for the second time, raising the tilted boat-shaped tea infuser and its connected conical top. This lifts the water-blocking device of the brewing container, allowing the second infusion of tea in the brewing container to flow out from the outlet and into the tilted boat-shaped tea infuser. From its outlet, through the second tea guide pipe or channel and the spout, the tea flows into the second fairness cup located below the spout, completing the second infusion. This process is repeated until the required number of infusions is completed. For example, if this application has 6 fairness cups, this completes 6 infusions, with each infusion flowing into its corresponding fairness cup. ;

[0044] Furthermore, the cylindrical cavity preferably located under the steering gear can be fitted with a bearing, and its base can also be fitted with a bearing, connected to the outer casing via the bearings. This allows the steering gear, its cylindrical cavity, and its base to rotate, while the outer casing remains stationary. The bearings enable flexible rotation of the steering gear, and the bearings, cylindrical cavity, base, and outer casing provide positioning, load-bearing capacity, and protection for the entire steering gear. The shafts of the functional gear and reduction gear can also be fitted with bearings, connected to the outer casing via the bearings. This allows the functional gear and reduction gear to rotate flexibly via the bearings, and the bearings and outer casing provide positioning, load-bearing capacity, and protection.

[0045] Furthermore, a cylinder or barrel is provided on the lower part of the prism of the ejector. One side of the cylinder or barrel has a curved surface 18, which is preferably a curved surface with anti-slip teeth. Preferably, the center line of the prism coincides with the center line of the cylinder or barrel. In order to prevent the curved surface on one side of the cylinder or barrel at the lower part of the ejector from swinging when the ejector moves up and down, an annular limiting wall 17 is provided on the circular platform on the functional gear 5. The curved surface on one side of the cylinder or barrel at the lower part of the ejector rests against the annular limiting wall 17 provided on the circular platform on the functional gear. At this time, the driven gear is located on the annular limiting wall. The lower end of the spring rests on the bottom of the cylinder or barrel at the lower part of the prism, and the upper end rests on the bottom surface of the steering gear located on the cylindrical cavity. The spring can be placed inside the cylinder or barrel. Alternatively, the spring can be placed inside or outside a cylindrical cavity, or inside or outside a cylindrical cavity. The upper end of the spring is fixed to the bottom surface of the steering gear or inside the cylindrical cavity, and the lower end is fixed to the cylinder or cylinder, so that the ejector part can return to its position and move downward under the action of the spring. The tilted boat-shaped teacup and its conical top also move downward under the action of gravity. Vertical guide teeth are provided on the curved surface to facilitate the up and down movement of the ejector part. At this time, the curved surface provided on the lower cylindrical side of the ejector part just touches the annular limiting wall provided on the truncated cone of the functional gear. The rotation of the functional gear causes the driven gear to rotate synchronously with it. The number of teeth of the driven gear is much smaller than the number of teeth of the steering gear. The rotation of the driven gear drives the steering gear to rotate very slowly, that is, the steering gear rotates slowly.

[0046] Furthermore, the ejector pin may have a cylindrical sleeve fitted over its prism. The cylindrical sleeve is fixed to the outer shell. The spring may be placed inside or outside the cylindrical cavity, or / and inside the cylindrical sleeve. The upper end is fixed to the bottom surface of the steering gear or inside the cylindrical cavity, and the lower end is fixed to the prism of the ejector pin. The prism of the ejector pin does not contact the cylindrical sleeve. The function of the cylindrical sleeve is to hold the prism of the ejector pin so that it is not easy to swing when moving up and down, so that the ejector pin can return to its position and move down under the action of the spring. The tilted boat-shaped teacup and its conical top also move down under the action of gravity.

[0047] Furthermore, the buckle plate, the upright plate, and the steering gear are integrally formed.

[0048] Furthermore, the frustum and the functional gear are integrally formed, and the arc-shaped bosses are evenly spaced along the circumference of the frustum.

[0049] Furthermore, the number of the arc-shaped protrusions is at least two, and the central angle between two adjacent arc-shaped protrusions is equal.

[0050] Furthermore, the output shaft of the geared motor is provided with a worm gear meshing with a reduction gear to realize the transmission connection between the geared motor and the reduction gear.

[0051] Furthermore, the conical top and the teacup are integrally formed, and the lifting end face of the conical top is designed as a smooth arc surface.

[0052] Furthermore, the lower end of the ejector is a smooth support end face, and the support end face is adapted to fit and conform to the table surface and the arc-shaped boss of the frustum.

[0053] Furthermore, the upper part of the steering gear is provided with at least two buckle plates with snap-fit ​​ends. These buckle plates extend into a groove adjacent to and above the guide groove, through a guide groove on the bottom of the steering positioning block that matches the size and shape of the buckle plate. When the steering positioning block moves upward, the buckle plates can hook onto the step formed between the groove and the guide groove in the steering positioning block, preventing the steering positioning block from detaching from the buckle plates. Assembly state: The buckle plate is inserted along the bottom guide groove of the positioning block, and the snap-fit ​​moves upward into the groove. At this time, the snap-fit ​​does not contact the step, and the positioning block can slide axially along the buckle plate. Upward anti-detachment: The steering positioning block moves upward until the snap-fit ​​is blocked by the step between the guide groove and the groove; the snap-fit ​​hooks onto the step, forming an axial limit, preventing the steering positioning block from moving further upward or detaching from the buckle plate. Downward reset: A downward reset force (the gravity of an inverted, tilted boat-shaped teacup) is applied, causing the steering positioning block to move downward, causing the snap-fit ​​to leave the step and return to the groove. The guide groove of the steering positioning block can then slide downward along the buckle plate to its initial position. Additional functions: The buckle plate constrains the guide groove throughout its entire length, allowing the steering positioning block to move up and down along the buckle plate while preventing radial swaying and ensuring motion accuracy. Buckle plate design, quantity: preferably 2 (symmetrically arranged) or 3 (triangularly distributed) to balance force and prevent swaying; must match the weight and operating load of the steering positioning block. Buckle: hook angle 15°-30° to avoid jamming; material selected is 65Mn spring steel to ensure elasticity and wear resistance; surface hardening treatment (HRC45-50) is required to extend service life. Steering positioning block design, guide groove: the gap between the buckle plate and its buckle is controlled at a certain distance to ensure that the buckle plate and its elastic buckle can pass through the guide groove. Too large a gap will cause swaying, and too small a gap will cause the buckle to jam; the surface roughness of the groove wall Ra≤1.6μm to reduce friction. Step: end face perpendicularity ≤0.02mm to ensure that the buckle fits snugly against the step surface; step height ≥1.2 times the buckle thickness to prevent the buckle from slipping out. Groove: Depth ≥ travel of the buckle and its clips + 1mm, allowing for upward movement allowance; width 0.1-0.2mm wider than the clips for easy clip insertion and removal. Assembly and tolerances, coaxiality: coaxiality between the buckle and the guide groove ≤0.03mm to avoid jamming.

[0054] Furthermore, the upper part of the steering gear is provided with at least two buckles. The upper end may not have a buckle. In this case, the steering positioning block is provided with a groove, so there is no need for a guide groove. The depth of the groove is less than the stroke of the buckle. In this way, the steering positioning block will not detach from the buckle when it moves up and down. The gap between the groove and the buckle is controlled at a certain distance to ensure that the buckle can pass through the groove. If the gap is too large, it will easily shake. If it is too small, the buckle will easily get stuck.

[0055] Furthermore, contacts 14 are evenly distributed below the functional gear 5. The number of contacts can be twice the number of arc-shaped bosses, and the positions of the contacts correspond to the positions of the arc-shaped bosses. For example, a contact is provided below the functional gear whose position corresponds to the frustum between every two adjacent arc-shaped bosses, and a contact is provided below the functional gear whose position corresponds to the arc apex of the arc-shaped boss. A micro switch 15 is provided below the functional gear that can contact the contacts. The micro switch is connected to the geared motor through a power supply. When the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector rises from one side of the arc-shaped boss along the arc surface of the arc-shaped boss and reaches the arc apex. At this time, the contacts below the functional gear contact the micro switch, and the micro switch disconnects the power supply to the geared motor, making... The geared motor stops rotating, allowing the tea in the brewing container to flow out of the spout for a certain period of time, eventually completing one infusion. At this point, pressing the power button for the second infusion starts the geared motor, causing the functional gear to rotate. The arc-shaped protrusion at the lower end of the ejector piece descends from the apex of the arc-shaped boss along its downward arc surface. At this moment, the water-blocking device in the brewing container closes, and the spout also closes. The second water pump button is then activated, drawing boiling water from the kettle into the brewing container used for the first infusion for the second. When the arc-shaped protrusion at the lower end of the ejector piece is positioned on the frustum between the first and second arc-shaped bosses, the contact point on the bottom of the functional gear contacts the microswitch. This microswitch then disconnects the power to the geared motor, causing the geared motor to... The motor stops rotating, allowing the tea in the brewing container to steep for a certain period. Then, pressing the second infusion button starts the geared motor. As the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector is carried by the gear, rising from one side of its arc-shaped protrusion along its curved surface. When it reaches the apex, the contact point below the functional gear engages with the microswitch, disconnecting the power to the geared motor and stopping it. This allows the tea in the brewing container to flow out of the spout for a certain period, eventually completing the second infusion. Pressing the third infusion button then starts the geared motor, and the functional gear rotates. The arc-shaped protrusion at the lower end of the ejector moves downwards along the curved surface of the arc-shaped protrusion, moving from the apex. At this point, the water-blocking device in the tea brewing container closes, and the water outlet of the tea brewing container also closes. The third water pump button is activated, and boiling water from the kettle is pumped into the tea brewing container (which has already undergone the second infusion) for the third infusion. When the arc-shaped protrusion at the lower end of the ejector is positioned on the frustum between the second and third arc-shaped protrusions, the contact point on the bottom of the functional gear contacts the microswitch. At this time, the microswitch disconnects the power to the geared motor, stopping its rotation and allowing the tea in the brewing container to steep for a certain period. Pressing the third infusion button then repeats the second infusion process, and so on, completing the second infusion and ultimately fulfilling the number of infusions set in this application. The tea leaves in the brewing container are then cleaned, and new tea can be brewed. A typical microswitch consists of a housing, actuator, contacts, and a spring mechanism.The housing is made of plastic or metal to protect the internal components; the actuator can take the form of a lever, button, roller, etc., and activates the switch through physical operation; the contacts include a common C terminal, a normally open NO terminal, and a normally closed NC terminal; the spring mechanism provides a rapid action function; the micro switch of this application can use a normally closed terminal.

[0056] Furthermore, a reversing arm 16 is provided on the functional gear 5, and a trigger switch is provided on the side of the functional gear. The trigger switch is connected to the geared motor via a power source. When the tea soup from the first brewing in the tea brewing container is output to the first fairness cup, the tea soup from the second brewing is output to the second fairness cup, and so on, after the number of brewing times is completed (e.g., 6 brews), the trigger switch touches the reversing arm 16 on the functional gear, triggering the switch to activate, causing the geared motor to reverse, the functional gear to rotate, and the tilted boat-shaped tea cup to return to the starting position, ready for the next brewing of new tea.

[0057] Furthermore, the water-blocking device can adopt a water outlet valve as disclosed in Chinese patent document CN202420490845.2, or a swing check valve as described below. These are existing technology products. The core components are: valve body, valve disc (or rocker arm with sealing ring), pin, valve seat, and spring (some models have springs). The valve disc rotates around the pin to seal the water outlet, or the rocker arm with sealing ring rotates around the pin to seal the water outlet. The sealing of the model depends on water pressure and the weight of the valve disc or the rocker arm with a sealing ring. In high-pressure conditions, a spring-loaded swing check valve can be selected. The spring assists the valve disc or the rocker arm with a sealing ring to press the outlet on the valve seat, improving the sealing effect. When working, the tilted boat-shaped teacup and its connected conical top rise and lift the valve disc or the rocker arm with a sealing ring of the water-blocking device of the tea brewing container to open the outlet, so that the tea in the tea brewing container can flow out from the outlet and into the tilted boat-shaped teacup.

[0058] Example 2 (Simple Tea Maker)

[0059] This embodiment is based on the rising and rotating device (also called a tea dispensing cup dispenser) for tea brewing machine in Embodiment 1, with the addition of various auxiliary structures, such as: a base for placing the fairness cup, a kettle and a main unit. The base has multiple cup sleeves distributed on it, each cup sleeve can hold the fairness cup, and a heat preservation device can be installed under the cup sleeve to keep each fairness cup warm. The heat preservation device has a heater inside, and the heater is connected to a power source through a switch to heat the water. The kettle is located on one side of the tea-brewing machine's tea-dispensing rising and rotating device. The kettle contains an instant heater, which is connected to a power source via a switch. This heater heats the cold water pumped into the kettle to boiling water. The boiling water is then pumped into the tea-brewing container through the hot water inlet. The tea-brewing container has a water outlet at its bottom, equipped with a water-blocking device. This device can be a swing-type check valve, a current technology. Its core components include: valve body, valve disc (or rocker arm with sealing ring), pin, valve seat, and spring (some models have springs). The valve disc rotates around the pin to seal the water outlet, or the rocker arm with sealing ring rotates around the pin to seal the water outlet. (Common models...) The sealing depends on water pressure and valve weight. In high-pressure conditions, a spring-loaded swing check valve can be used. The spring assists the valve disc in pressing the outlet of the valve seat, improving the sealing effect. During operation, the tilted boat-shaped teacup and its connected conical top rise into position, lifting the valve disc of the water-blocking device of the tea brewing container or the rocker arm with a sealing ring to open the outlet, allowing the tea in the tea brewing container to flow out from the outlet and into the tilted boat-shaped teacup. From the tea outlet, the tea flows through the tea guide pipe or guide channel and the tea guide pipe spout to the fairness cup located on the base below the tea guide pipe spout. The tea guide pipe or guide channel is covered with a kettle lid, and the kettle is located below the tea guide pipe or guide channel. The lifting and rotating device for dispensing tea in a tea maker can be located externally or internally. The main unit contains the required number of control buttons, each capable of controlling the power supply, heater startup and shutdown, instant heater startup and shutdown, water pump startup and shutdown, microswitch startup, trigger switch startup, and geared motor startup and shutdown. For example, the following process can be achieved: 1) When the tea maker / water boiling power button is activated, the water pump draws a certain amount of water into the kettle for boiling. A water level sensor in the kettle (such as a float switch, where the float rises and falls with the water level, directly driving a water pump switch such as a relay switch to turn the pump off or on; or a level gauge, where a certain water level is observed through the viewing window, and the power switch cuts off the power to stop the water pump).2) When the kettle's temperature control switch senses that the water inside is boiling water, or when the thermometer displays a specific temperature, you can see the thermometer showing 100 degrees Celsius through the viewing window. This activates the first water pump button, drawing boiling water from the kettle into the tea brewing container. Once a certain amount is reached, the water level sensor in the tea brewing container shuts off the water pump (e.g., a float switch; the float rises and falls with the water level, directly driving the water pump switch, such as a relay switch, to turn the water pump on or off). 3) Brew the tea leaves in the tea brewing container. After a certain brewing time, press the first brew power button. The reduction motor starts, driving the functional gear and the steering gear. As the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector rises along the arc surface of the protrusion, reaching the apex. At this point, the arc-shaped protrusion at the lower end of the ejector... During the upward movement, the spherical body at the top of the ejector can press against the steering positioning block, the tilted boat-shaped teacup, and the conical top of the tilted boat-shaped teacup, causing the tilted boat-shaped teacup and its connected conical top to rise into position. This lifts the valve of the water-blocking device of the tea brewing container or the rocker arm with a sealing ring to open the water outlet, allowing the tea in the tea brewing container to flow out from the water outlet and into the tilted boat-shaped teacup. From its tea outlet, through the first tea guide pipe or guide channel and the first tea guide pipe nozzle, the tea flows into the first fairness cup located on the base below the first tea guide pipe nozzle. At the same time, the contact point under the functional gear contacts the micro switch. At this time, the micro switch disconnects the power supply to the reduction motor, causing the reduction motor to stop rotating, allowing the tea in the tea brewing container to flow out from the water outlet for a certain period of time, eventually reaching the first fairness cup completely, completing the first brew.4) At this point, press the second power button. The reduction motor starts, the function gear rotates, and the arc-shaped protrusion at the lower end of the ejector piece descends from the top of the arc-shaped boss along the descending arc surface of the arc-shaped boss. The ejector piece returns to its original position and moves downward under the action of the spring. The tilted boat-shaped teacup and its conical top also move downward under the action of gravity. At this time, the water-blocking device in the tea brewing container closes, and the water outlet of the tea brewing container also closes (which can be seen through the viewing window). Turn on the second water pump button, and boiling water from the kettle is pumped into the tea leaves in the tea brewing container after the first infusion for the second infusion. After the water volume reaches a certain level, the water volume sensor in the tea brewing container (similar to the structure of a float switch) shuts off the water pump. The arc-shaped boss rotates, and when the arc-shaped protrusion at the lower end of the ejector piece is at the first arc... When the convex surface between the first and second arc-shaped protrusions is reached, the contact point on the bottom surface of the functional gear contacts the micro switch. At this time, the micro switch disconnects the power supply to the geared motor, causing the geared motor to stop rotating, allowing the tea in the tea brewing container to steep for a certain period of time. After steeping for a certain period of time, the second infusion button is pressed, and the geared motor starts. When the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector is carried by the functional gear from one side of its arc-shaped protrusion along the arc surface of the protrusion. When it reaches the top of the arc, the spherical body at the upper end of the ejector can press against the steering positioning block, the tilted boat-shaped teacup, and the conical top provided with the tilted boat-shaped teacup, causing the tilted boat-shaped teacup and its connected conical top to rise into position and lift the valve disc of the water-blocking device of the tea brewing container. The rocker arm with a sealing ring opens the water outlet, allowing the tea in the tea brewing container to flow out from the outlet and into the tilted boat-shaped teacup. From there, the tea flows through the second tea guide tube or guide channel and the second tea guide tube spout into the second fairness cup located on the base below the second tea guide tube spout. At the same time, the contact under the functional gear contacts the micro switch, which disconnects the power to the geared motor, stopping its rotation. This allows the tea in the tea brewing container to flow out from the outlet for a certain period of time, eventually completing the second infusion. 5) At this point, press the power button for the third infusion and repeat step 4). The geared motor starts, the functional gear rotates, and the arc-shaped protrusion at the lower end of the ejector part moves along the arc from the top of its arc-shaped protrusion as the functional gear rotates. The curved surface of the raised platform descends, at which point the water-blocking device in the tea brewing container closes, and the water outlet of the tea brewing container also closes (which can be seen through the viewing window). When the third water pump button is pressed, boiling water from the kettle is pumped into the tea leaves in the tea brewing container after the second infusion for the third infusion. The curved platform rotates, and when the curved protrusion at the lower end of the ejector is located on the frustum between the second and third curved platforms, the contact point on the bottom of the functional gear contacts the micro switch. At this time, the micro switch disconnects the power supply to the geared motor, causing the geared motor to stop rotating, allowing the tea in the tea brewing container to steep for a certain period of time. Then, the third infusion dispensing button is pressed, and the second infusion dispensing process is repeated, completing the third infusion. This process is repeated until the number of infusions set in this application is completed.When the trigger switch contacts the reversing arm on the functional gear, the switch activates, causing the geared motor to reverse. This rotates the functional gear, returning the tilted, boat-shaped teacup to its starting position. Alternatively, a reversing button for the geared motor can be activated to also rotate the functional gear and return the tilted, boat-shaped teacup to its starting position. Afterward, the tea leaves in the brewing container are removed, and the tea can be brewed for the next batch.

[0060] Example 3 (Tea maker based on a single-chip microcomputer)

[0061] This embodiment is based on the rising and rotating device (also called a tea dispensing cup dispenser) for tea brewing machine in Embodiment 1, with the addition of various auxiliary structures, such as: a base for placing the fairness cup, a kettle and a main unit. The base has multiple cup sleeves distributed on it, each cup sleeve can hold the fairness cup, and a heat preservation device can be installed under the cup sleeve to keep each fairness cup warm. The heat preservation device has a heater inside, and the heater is connected to a power source through a switch to heat the water. The kettle is located on one side of the tea-brewing machine's tea-dispensing rising and rotating device. The kettle contains an instant heater, which is connected to a power source via a switch. This heater heats the cold water pumped into the kettle to boiling water. The boiling water is then pumped into the tea-brewing container through the hot water inlet. The tea-brewing container has a water outlet at its bottom, equipped with a water-blocking device. This water-blocking device can be a swing-type check valve, a current technology product. Its core components include: valve body, valve disc (or rocker arm with sealing ring), pin, valve seat, and spring (some models have springs). The valve disc rotates around the pin to seal the water outlet, or the rocker arm with sealing ring rotates around the pin to seal the water outlet. The standard model has a sealing mechanism. Depending on the water pressure and valve weight, a spring-loaded swing check valve can be used in high-pressure conditions. The spring assists the valve disc in pressing the outlet of the valve seat, improving the sealing effect. During operation, the tilted boat-shaped teacup and its connected conical top rise into position, lifting the valve disc of the water-blocking device of the tea brewing container or the rocker arm with a sealing ring to open the outlet, allowing the tea in the tea brewing container to flow out from the outlet and into the tilted boat-shaped teacup. From the tea outlet, the tea guide pipe or guide channel flows through the tea guide pipe spout into the fairness cup located on the base below the tea guide pipe spout. The tea guide pipe or guide channel is covered with a kettle lid, and the kettle is located below the tea guide pipe or guide channel.The lifting and rotating device for dispensing tea in a tea maker can be located externally or internally. The main unit contains a microcontroller with a program that can be implemented by a technician. This program controls the power supply to start and stop the heater, the instant heater, the water pump, the microswitch, the trigger switch, and the geared motor. For example, it can achieve the following process: 1) When the tea-brewing button is pressed, the microcontroller's program controls the water pump to automatically draw a certain amount of water into the kettle for boiling; 2) When the microcontroller receives information from the kettle's temperature control switch that the water is boiling, it controls the water pump to draw a certain amount of water into the tea-brewing container; 3) The tea leaves in the tea-brewing container are brewed. After a certain brewing time, the microcontroller's program controls the geared motor to start working, driving the functional gear and the steering gear to rotate. The arc-shaped protrusion at the lower end of the ejector part then... When the functional gear rotates and the arc-shaped protrusion rises along the arc surface of the arc-shaped boss to the top of the arc, the lower end of the ejector part rises, and the spherical body at the upper end of the ejector part can press against the steering positioning block, the tilted boat-shaped teacup, and the conical top provided with the tilted boat-shaped teacup. This causes the tilted boat-shaped teacup and its connected conical top to rise into position, thereby lifting the valve disc of the water-blocking device of the tea brewing container or the rocker arm with a sealing ring to open the water outlet, allowing the tea in the tea brewing container to flow out from the water outlet. The tea flows into the tilted boat-shaped teacup, and from its outlet, through the first tea guide tube or guide channel, and the first tea guide tube spout, it flows into the first fairness cup located on the base below the first tea guide tube spout. At the same time, the contact under the functional gear contacts the micro switch. At this time, the micro switch sends a signal to the microcontroller, disconnects the power to the geared motor, and stops the geared motor from rotating. This allows the tea in the tea container to flow out from the outlet for a certain period of time, eventually flowing completely into the first fairness cup, completing the first brew.4) After the first infusion, the microcontroller starts the geared motor, the function gear rotates, and the arc-shaped protrusion at the lower end of the ejector descends from the top of the arc-shaped boss along the descending arc surface of the arc-shaped boss. The ejector returns to its original position under the action of the spring, and the tilted boat-shaped teacup and its conical top also move down under the action of gravity. At this time, the water-blocking device in the tea brewing container closes, and the water outlet of the tea brewing container also closes. The microcontroller then controls the water pump to work, and boiling water from the kettle is drawn into the tea brewing container after the first infusion. When the tea is steeped for the second time and the water level reaches a certain point, the water level sensor in the tea brewing container sends a signal to the microcontroller to shut off the water pump. When the arc-shaped protrusion at the bottom of the ejector is positioned on the frustum between the first and second arc-shaped protrusions, the contact point on the bottom of the functional gear contacts the microswitch. At this point, the microswitch sends a signal to the microcontroller to disconnect the power to the geared motor, causing it to stop rotating and allowing the tea in the brewing container to steep for a certain period of time. Then, the microcontroller controls the geared motor to start again. When the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector is carried by the functional gear from one side of its arc-shaped boss along the arc surface of the boss. When it reaches the top of the arc, the spherical body at the upper end of the ejector can press against the steering positioning block, the tilted boat-shaped teacup, and the conical top provided with the tilted boat-shaped teacup. This causes the tilted boat-shaped teacup and its connected conical top to rise into position, thereby lifting the valve disc of the water-blocking device of the tea brewing container or the rocker arm with a sealing ring to open the outlet, allowing the tea in the tea brewing container to flow out. The water flows out of the spout and into the tilted boat-shaped teacup. From the spout, it flows through the second tea guide tube or guide channel and the spout of the second tea guide tube into the second fairness cup located on the base below the spout. At the same time, the contact under the functional gear contacts the micro switch. At this time, the micro switch sends a signal to the microcontroller, disconnects the power to the geared motor, and stops the geared motor from rotating. This allows the tea in the brewing container to flow out of the spout for a certain period of time, eventually reaching complete flow, completing the second infusion. 5) The microcontroller controls the geared motor to drive the functional gear to continue rotating according to the number of fairness cups or the number of infusions requested by the user, repeating step 3) to achieve the number of infusions requested by the user; 6) After the number of infusions requested by the user is completed, the microcontroller program can request the geared motor to reverse back to its original position, or trigger the switch to contact the reverse arm on the functional gear and receive the signal from the trigger switch. The microcontroller program then controls the geared motor to reverse, the functional gear to rotate, and the tilted boat-shaped teacup to return to its starting position. Then clean the tea leaves from the tea container, and you can proceed with brewing the next batch of tea.

[0062] Example 4

[0063] The tea infusion rising and rotating device in this embodiment can be located outside or inside the main unit. The main unit is equipped with several control buttons, which can control the start, operation, heat preservation, and stop of the heater, instant heater, water pump, micro switch, trigger switch, and geared motor, respectively, realizing manual control of the entire tea brewing process. The specific working process is as follows:

[0064] 1. Turn on the power button for brewing tea and boiling water. The water pump will start and draw a certain amount of cold water into the kettle. The kettle is equipped with a water level sensor (such as a float switch, which rises and falls with the water level and can directly drive the relay switch of the water pump to start and stop the water pump; or a level gauge, which allows you to manually turn off the water pump after observing the water level through the window and reaching the preset value) to ensure that the water level in the kettle is sufficient for brewing tea.

[0065] 2. When the temperature control switch inside the kettle senses that the water temperature has reached boiling point (100℃), or when the thermometer in the viewing window shows that the water temperature is 100℃, the first water pump button is activated, and the water pump draws the boiling water from the kettle into the tea brewing container. When the water level in the tea brewing container reaches the preset value, the water level sensor (such as a float switch) in the tea brewing container automatically shuts off the water pump and stops the water supply.

[0066] 3. After the tea leaves have been steeped in the tea brewing container for a certain period of time, press the power button for the first brew. The reduction motor starts, driving the functional gear to rotate, which in turn drives the steering gear to rotate slowly. When the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector rises along the upper arc surface of the arc-shaped boss. When it reaches the top of the arc, the spherical body at the upper end of the ejector pushes the steering positioning block, the boat-shaped tea infuser, and the conical top to move upwards simultaneously. After the conical top rises to its position, it lifts the valve disc of the water-blocking device (or the rocker arm with a sealing ring), opening the water outlet. The tea in the tea brewing container flows into the boat-shaped tea infuser, then through the tea outlet, the first tea guide pipe (or guide groove), and the first tea guide pipe spout, into the first fairness cup on the base. At the same time, the contact point below the functional gear contacts the micro switch, which disconnects the power to the reduction motor, stopping the reduction motor from rotating and ensuring that the tea has sufficient time to flow out completely, thus completing the first brew.

[0067] 4. Press the second infusion power button. The reduction motor starts, the function gear rotates, and the arc-shaped protrusion at the lower end of the ejector descends along the downward slope of the arc-shaped boss. Under the action of the spring return force, the ejector moves downward, and the boat-shaped teacup and the conical top move downward simultaneously under the action of gravity. The water-blocking device closes, sealing the water outlet of the tea brewing container (the closing status can be observed through the viewing window). Turn on the second water pump button, and boiling water from the kettle is drawn into the tea brewing container for a second infusion of the tea leaves after the first infusion. When the water level in the tea brewing container reaches the preset value, the water... The metering sensor automatically shuts off the water pump; the functional gear continues to rotate, and when the arc-shaped protrusion at the lower end of the ejector is located on the frustum between the first and second arc-shaped protrusions, the contact point on the bottom of the functional gear contacts the micro switch, the micro switch disconnects the power supply to the geared motor, causing the geared motor to stop rotating, and the tea is left to steep for a certain period of time; after steeping, press the second infusion button, the geared motor starts, and the tea-dispensing process in step 3 is repeated, the tea flows through the second tea guide pipe (or guide channel) and the second tea guide pipe spout into the second fairness cup, completing the second infusion.

[0068] 5. Press the power button for the third infusion and repeat step 4 to complete the third infusion and subsequent preset infusions. After completing all infusions, the trigger switch contacts the reverse arm on the function gear, triggering the switch to reverse the geared motor and return the boat-shaped tea infuser to its starting position. Alternatively, a reverse button can be set for the geared motor to be manually activated to reset the boat-shaped tea infuser. After cleaning the tea leaves from the brewing container, you can proceed with the next round of brewing.

[0069] Example 5

[0070] This embodiment, based on the tea brewing machine tea infusion rising and rotating device (tea water dispensing cup dispenser) described in Embodiment 1, adds various auxiliary structures, including: a base for placing the fairness cup, a kettle, and a main unit, forming a single-chip microcomputer-based tea brewing machine; the mechanical parts of its auxiliary structures (base, cup sleeve, heat preservation device, kettle, instant heater, water blocking device, etc.) are the same as in Embodiment 2, the core difference being the use of a single-chip microcomputer to achieve fully automated control of the entire process, the specific structure and workflow are as follows.

[0071] The mechanical structures of the base, kettle, heat preservation device, and water-blocking device are exactly the same as in Embodiment 2, and will not be repeated here. The tea-pouring rising and rotating device can be located outside or inside the main unit. The main unit is equipped with a microcontroller with a built-in control program that can be conventionally implemented by those skilled in the art. This program can automatically control the start, operation, heat preservation, and stop of the heater, instant heater, water pump, micro switch, trigger switch, and geared motor, realizing the automated operation of the entire tea brewing process. The specific working process is as follows:

[0072] 1. When the tea brewing button is pressed, the program inside the microcontroller automatically controls the water pump to start, drawing a certain amount of cold water into the kettle to complete the preparation for boiling water; the water level sensor inside the kettle detects the water level in real time, and when the water level reaches the preset value, it sends a signal to the microcontroller, which then controls the water pump to stop working.

[0073] 2. The temperature control switch inside the kettle monitors the water temperature in real time. When it senses that the water temperature has reached boiling point (100℃), it sends a signal to the microcontroller. After receiving the signal, the microcontroller controls the water pump to start, drawing a certain amount of boiling water from the kettle into the tea brewing container. When the water level in the tea brewing container reaches the preset value, its water level sensor sends a signal to the microcontroller, which then controls the water pump to stop working.

[0074] 3. The microcontroller controls the tea to steep for a certain period of time according to a preset program. After steeping, the microcontroller controls the geared motor to start, which drives the functional gear to rotate, and then drives the steering gear to rotate slowly. When the functional gear rotates, the arc-shaped protrusion at the lower end of the ejector rises along the upper arc surface of the arc-shaped boss. When it reaches the top of the arc, the spherical body at the upper end of the ejector pushes the steering positioning block, the boat-shaped teacup, and the conical top to move upwards simultaneously. The conical top lifts the water blocking device, opens the water outlet, and the tea flows through the boat-shaped teacup, the first tea guide pipe (or guide channel), and into the first fairness cup. At the same time, the contact point below the functional gear contacts the micro switch, and the micro switch sends a signal to the microcontroller. The microcontroller controls the geared motor to stop rotating, ensuring that the tea flows out completely, completing the first steeping.

[0075] 4. After the first infusion, the microcontroller automatically starts the geared motor, the function gear rotates, and the arc-shaped protrusion at the lower end of the ejector descends along the downward slope of the arc-shaped boss. The ejector, the boat-shaped teacup, and the conical top move down simultaneously, closing the water-blocking device and sealing the water outlet of the tea brewing container. The microcontroller then controls the water pump to start, drawing boiling water from the kettle into the tea brewing container for the second infusion. When the water level in the tea brewing container reaches the preset value, the water level sensor sends a signal to the microcontroller, which then controls the water pump to stop. The function gear continues to rotate. When the arc-shaped protrusion at the lower end of the ejector is located on the frustum between two adjacent arc-shaped bosses, the contact point on the bottom of the function gear contacts the microswitch. The microswitch sends a signal to the microcontroller, which then controls the geared motor to stop rotating, allowing the tea to steep for a certain period. After the second infusion, the microcontroller controls the geared motor to start again, repeating the tea-pouring process in step 3 to complete the second infusion.

[0076] 5. The microcontroller automatically controls the geared motor to drive the function gear to rotate continuously according to the preset number of fair cups (or the number of bubbles set by the user), repeating the operation of steps 3-4 in sequence to complete all preset number of bubbles.

[0077] 6. After all the brewing times are completed, there are two reset methods: one is that the microcontroller program presets and controls the geared motor to reverse, driving the boat-shaped teacup back to the starting position; the other is that the trigger switch contacts the reverse arm on the function gear, the trigger switch sends a signal to the microcontroller, the microcontroller controls the geared motor to reverse, and realizes the reset of the boat-shaped teacup; after cleaning the tea residue in the tea brewing container, you can start brewing the next round of new tea.

[0078] Circuit design (including microswitch adapter)

[0079] The core of this circuit design is adapted to the above three embodiments, focusing on the signal transmission and control logic of the micro switch. It works in conjunction with components such as the geared motor, water pump, instant heater, and trigger switch. It is powered by a safe DC24V voltage and supports both manual control (Embodiment 2) and microcontroller automatic control (Embodiment 3) modes to ensure that the micro switch accurately controls the start and stop of the geared motor and is suitable for the need for multiple brewing and continuous tea production. The specific design is as follows.

[0080] I. Core Circuit Architecture

[0081] The circuit is divided into three main modules: main power supply circuit, control circuit, and execution circuit. All circuits are integrated into the control circuit board inside the host. The micro switch is the core detection and control component, connected to the control circuit, and linked with the geared motor, microcontroller (Example 3), and control button (Example 2). The core logic is: external mains power → power module step-down rectification → main power supply output → control circuit (including micro switch) trigger → execution circuit (geared motor, water pump, etc.) action. It achieves precise control throughout the process and is adapted to the workflow of each embodiment.

[0082] II. Detailed Design of Each Module (Focusing on Microswitch Compatibility)

[0083] 2.1 Main power supply circuit

[0084] 1. Power input: Connect to AC220V mains power, with an additional main power switch and 2A / 250V fuse for circuit overload and short circuit protection, preventing damage to core components such as microswitches and geared motors from abnormal mains power; the main power switch is integrated into the host control panel for easy operation.

[0085] 2. Step-down rectification: The isolated switching power supply module converts AC220V mains power to DC24V (powering the geared motor, water pump, and micro switch) and DC5V (powering the microcontroller, control buttons, and indicator lights). The power supply module is moisture-proof and anti-interference, suitable for the hot and humid working environment of the tea maker. The output voltage fluctuation is ≤±5%, ensuring the stable operation of components such as micro switches and microcontrollers and avoiding false signal triggering caused by voltage fluctuations.

[0086] 2.2 Control loop (core adapter micro switch)

[0087] The control loop consists of a microswitch, a trigger switch, control buttons (Example 2), a microcontroller (Example 3), and indicator lights. Its core function is to control the start and stop of the geared motor using the microswitch. It adapts to the working logic of each embodiment and is designed with two control modes:

[0088] 1. Microswitch Selection and Wiring: Select a normally closed microswitch (consistent with the descriptions in Examples 1, 2, and 3), model KW12-3Z, which is waterproof and wear-resistant, suitable for the installation environment below the functional gear; connect the common C terminal of the microswitch to a DC24V power supply, connect the normally closed NC terminal to the control terminal of the geared motor, and leave the moving NO terminal floating; the contacts below the functional gear correspond to the actuator of the microswitch. When the contacts touch the microswitch actuator, the microswitch actuates, the normally closed NC terminal opens, cutting off the power supply to the geared motor and stopping its rotation; when the contacts disengage from the microswitch actuator, the microswitch resets, the normally closed NC terminal closes, and the geared motor can start normally.

[0089] 2. Manual Control Mode (Adapted to Example 2): The main unit control panel has several control buttons, including a tea brewing and water boiling button, a water pump button, water dispensing buttons for each brew, and a geared motor reversal button. The buttons are waterproof and touch-sensitive. The control buttons and microswitches are connected in parallel to the control circuit. When a button is pressed, the geared motor can be forcibly started or stopped, forming a dual control system with the microswitch to ensure operational flexibility. For example, pressing the first brew dispensing button starts the geared motor, and the functional gear rotates. When the contact point touches the microswitch, the microswitch disconnects the power supply to the geared motor, completing one brew. If it is necessary to stop midway, the geared motor stop button can be manually pressed to forcibly cut off the power.

[0090] 3. Automatic Control Mode (Adapted for Example 3): The host is equipped with a microcontroller (such as STC89C52). The moving end (NO) of the microswitch is connected to the I / O port of the microcontroller, transmitting the microswitch's action signal to the microcontroller. The microcontroller has a built-in control program that, upon receiving the signal from the microswitch, automatically controls the start and stop of the geared motor and the operation of the water pump, eliminating the need for manual operation. For example, when the functional gear contact contacts the microswitch, the microswitch sends a "stop signal" to the microcontroller, which immediately cuts off the power to the geared motor and simultaneously controls the water pump to start, supplying water for the next brewing cycle, thus achieving full automation of the process.

[0091] 4. Trigger switch linkage: The trigger switch and micro switch are connected in parallel to the control circuit. One end of the trigger switch is connected to a DC24V power supply, and the other end is connected to the microcontroller (Example 3) or control button (Example 2). At the same time, it is linked with the reverse control terminal of the geared motor. When the preset number of teas is completed, the reverse arm on the functional gear contacts the trigger switch, the trigger switch is activated, and a "reset signal" is sent to the microcontroller (Example 3), or the geared motor is directly controlled to reverse (Example 2), which drives the boat-shaped teacup back to the starting position. At this time, the micro switch is in the reset state and waits for the next round of work.

[0092] 5. Indicator light linkage: A status indicator light is added to the control circuit, which is linked with the micro switch and the geared motor. When the geared motor is running, the indicator light is green. When the micro switch is activated and the geared motor stops, the indicator light turns yellow and an audible prompt (such as a buzzer) is triggered to inform the user that a brewing session has been completed or the process has entered the resting brewing stage, thus improving the ease of operation.

[0093] 2.3 Execution loop

[0094] The execution circuit consists of a geared motor, a water pump, an instant heater, and a heater (for heat preservation). All components are connected to a DC 24V power supply and are controlled by a control circuit (microswitch, microcontroller, control buttons) to start and stop. The core component is a microswitch that controls the geared motor, as detailed below:

[0095] 1. Gear motor control: The gear motor is connected in series with a micro switch, a microcontroller (Example 3) or a control button (Example 2). The micro switch serves as the core start-stop control point to achieve precise start and stop of the gear motor. The forward and reverse rotation of the gear motor is controlled by a trigger switch or a microcontroller. When reversing, it is used to reset the boat-shaped teacup. During the reversal process, the micro switch does not participate in the control to ensure smooth reset action.

[0096] 2. Control of other components: The water pump, instant heater, and heat preservation heater are all connected to the control circuit via relays and are controlled to start and stop by control buttons (Example 2) or microcontrollers (Example 3), working in conjunction with the action logic of the micro switch; for example, when the micro switch is activated and the geared motor stops (the tea water has completely flowed out), the microcontroller (Example 3) automatically controls the water pump to start, injecting boiling water into the tea brewing container to prepare for the next brewing; in manual mode, the user can manually press the water pump button to inject boiling water after the micro switch triggers the geared motor to stop.

[0097] III. Circuit Protection and Adaptor Design

[0098] 1. Safety Protection: In addition to the main circuit fuse, micro switches, geared motors, water pumps and other components are all connected in series with overcurrent protection resistors to prevent short circuits and burnout; the control circuit board is treated with a waterproof coating, and waterproof connectors are added to the wiring points of the micro switches to adapt to the hot and humid working environment of the tea maker and avoid moisture causing false signal triggering or short circuits; all circuit interfaces are designed to prevent incorrect wiring from damaging the micro switches and other components.

[0099] 2. Adaptability Design: The circuit has reserved expansion interfaces, which can be flexibly adapted according to the differences of the three embodiments; Embodiment 1 only uses the geared motor, micro switch, and trigger switch related circuits, without needing to connect the water pump and instant heater control circuits; Embodiment 2 uses the manual control button, micro switch, trigger switch and all actuator circuits; Embodiment 3 only needs to connect a microcontroller on the basis of Embodiment 2 to realize automatic control, without changing the wiring and control logic of the micro switch, which has strong versatility.

[0100] 3. Anti-interference design: The control circuit and the execution circuit are wired separately to reduce electromagnetic interference and prevent interference signals generated by the geared motor and water pump from affecting the signal transmission of the micro switch; a filter capacitor is added to the power supply terminal of the microcontroller to filter voltage fluctuations and ensure that the microcontroller accurately receives the signal from the micro switch; the wiring of the micro switch uses shielded wire to further improve anti-interference performance and avoid false triggering of signals.

[0101] IV. Circuit Control Logic (Focusing on the function of microswitches)

[0102] 1. Manual Mode (Example 2) Control Logic: Power on → Main power switch closed → DC24V / DC5V power output → Microswitch reset (normally closed terminal closed); Press the tea brewing / boiling button → Water pump starts, kettle boils water → Water temperature reaches 100℃, press the first brew dispensing button → Gear motor starts, function gear rotates → Ejector rises, conical top lifts water blocking device, tea flows to fairness cup → Function gear contact contacts microswitch → Microswitch actuates, normally closed terminal opens, gear motor stops. The indicator light turns yellow and a buzzer sounds → the tea has completely flowed out, completing one brew; press the power button for the second brew → the geared motor starts, the function gear rotates, the contacts disengage from the microswitch, the microswitch resets → the arc-shaped protrusion descends, the water-blocking device closes → press the water pump button to inject boiling water → the contacts contact the microswitch (between adjacent arc-shaped protrusions) → the geared motor stops, allowing the tea to steep → press the second brew dispensing button, repeating the above process until the preset number of brews is completed → the trigger switch contacts the reverse arm → the geared motor reverses and resets → power off.

[0103] 2. Automatic Mode (Example 3) Control Logic: Power on → Start tea brewing button → Microcontroller initialization → Control water pump to start, kettle boils water → Temperature control switch sends boiling water signal to microcontroller → Microcontroller controls water pump to inject boiling water into tea brewing container → Let steeping for preset time → Microcontroller controls geared motor to start, function gear rotates → Contact contacts micro switch → Micro switch sends signal to microcontroller → Microcontroller controls geared motor to stop, buzzer sounds → Tea is completely poured out, one brew is complete → Microcontroller controls water pump to start, injects boiling water → Contact contacts micro switch (between adjacent arc-shaped protrusions) → Microcontroller controls geared motor to stop, let steeping continue → Repeat the tea dispensing and brewing process until the preset number of brews is completed → Trigger switch sends reset signal to microcontroller → Microcontroller controls geared motor to reverse, reset → Wait for the next round of operation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
