Description

Technical Field

[0001] The present invention relates to the technical field of tea making, in particular to an automatic tea making machine. Background Art

[0002] With the accelerating pace of modern life and rising consumer health awareness, the market demand for milk tea and various teas, which combine leisure, socializing, and thirst quenching, has seen explosive growth. However, as the tea industry rapidly develops, inherent problems in traditional tea production have gradually emerged, particularly in the tea brewing process. These problems have seriously hindered the further development and quality improvement of the tea industry.

[0003] Currently, many tea shops rely primarily on manual labor for brewing tea. This manual brewing method has numerous drawbacks, including low efficiency and difficulty meeting the demands of large customer bases during peak hours. Furthermore, due to the instability of manual operation, product quality cannot be consistently and standardized, resulting in variations in taste and quality between batches of tea. While automated tea brewing devices exist, these devices typically require weighing the tea leaves before brewing to achieve precise brewing. This method requires a weighing device to obtain a fixed amount of tea leaves, which are then brewed with hot water. However, weighing not only complicates the hardware structure, requiring a dedicated weighing device to contact the tea leaves or expose them to the environment, but also adds an additional weighing step to the operational process, which undoubtedly increases operational complexity. Furthermore, since the tea leaves are easily affected by environmental factors during weighing and subsequent handling, as well as the limitations of weighing accuracy, it is difficult to ensure the stability and consistency of the tea soup quality, thus affecting the overall quality of the tea and the consumer experience.

[0148] See also Figures 1 to 22 The present invention provides an automatic tea making machine, comprising: a tea bag supplying device 1, which can store multiple tea bags and can output a number of tea bags in a quantitative manner; a tea making device 2, which can receive the tea bags output from the tea bag supplying device 1 and make tea, and can discharge the obtained hot tea soup and tea bag residues; a tea soup cooling device 3, which can receive the tea soup discharged from the tea making device 2 and cool it; a hot water supplying device 4, which is connected to the tea making device 2 and can supply hot water to the tea making device 2; a control system, which can receive various control signals and is control-connected to the tea bag supplying device 1, the tea making device 2, the tea soup cooling device 3 and the hot water supplying device 4.

[0149] The main operating principle of the automatic tea brewing machine disclosed herein is as follows: During operation, a tea bag supply device 1 stores multiple tea bags, each packaged according to a certain weight specification from tea ingredients. A control system determines the required number of tea bags based on tea brewing needs and controls the operation of the tea bag supply device 1, dispensing a corresponding amount of tea bags, which are then delivered to the tea brewing device 2. Based on the tea brewing needs, the control system controls the hot water supply device 4 to deliver a corresponding amount of hot water to the tea brewing device 2, where the tea bags are brewed, producing hot tea soup and residual tea bags. The hot tea soup is then conveyed to the tea soup cooling device 3, where it is promptly cooled to preserve the original tea flavor as much as possible. The cooled tea soup can then be transported to a designated location for storage or use. The automatic tea brewing machine disclosed herein facilitates automatic tea brewing using tea bags and can obtain a specific amount of tea as needed. Compared to automatic tea brewing using bulk tea ingredients, it does not require a weighing mechanism or other device for quantitatively obtaining bulk tea. Its structure is simpler, and the required operation and control procedures are also simpler.

[0150] See also Figures 1 to 22 The present invention will be further described below with reference to specific embodiments:

[0151] Tea bag supply device 1:

[0152] See also Figures 5 to 9 , is a schematic structural diagram of the tea bag supply device 1 in this embodiment. In this embodiment, the tea bag supply device 1 includes a conveyor belt mechanism 11, a conveyor drive mechanism 13, and a tea placing mechanism 12. The conveyor belt mechanism 11 includes two parallel belt shafts 112 and a conveyor belt 111 mounted on each of the two belt shafts 112 at both ends. The two belt shafts 112 support and drive the conveyor belt 111. The conveyor belt mechanism 11 can specifically adopt an existing design structure. The conveying drive mechanism 13 is connected to the conveyor belt mechanism 11 in a transmission manner and can drive the conveyor belt 111 to move; the plane on which the axis lines of the two belt shafts 112 of the conveyor belt mechanism 11 are located is the conveying positioning plane 114, the angle between the conveying positioning plane 114 and the vertical plane is 0 to 60 degrees, and the angle between the belt shaft 112 and the horizontal plane is 0 to 30 degrees. There are multiple tea placing mechanisms 12, which are fixedly arranged on the conveyor belt 111 at intervals. Tea placing structures 121 for placing tea bags are provided on opposite sides of the tea placing mechanism 12 along the movement direction of the conveyor belt 111.

[0153] The main working principle of the automatic tea brewing device is: Figure 4The section of the conveyor belt 111 between the two belt shafts 112 is stretched and flat. When the belt shafts 112 of the conveyor belt mechanism 11 rotate, the belt shafts 112 drive the conveyor belt 111 to move, causing one side of the stretched and flat section of the conveyor belt 111 to rise. For ease of explanation, this side is referred to as the left side, and the upwardly stretched and flat section is referred to as the ascending section 1111. Correspondingly, the other side (i.e., the right side) descends, and the downwardly stretched and flat section is referred to as the descending section 1112. Tea bags can be placed on the upwardly facing tea placement structures 121 of the tea placement mechanisms 12 located on the ascending section 1111 and the descending section 1112. The tea placement structures 121 can be surfaces capable of supporting tea bags (flat or concavely curved), or can be a container capable of holding and preventing tea bags from slipping out. The number of tea bags placed on each tea placement mechanism 12 is preferably the same, but can also be different. Before feeding, the tea bag supply device 1 can store multiple tea bags for subsequent continuous output of tea bags. When the tea bags need to be output, the conveying drive mechanism 13 is controlled to move, driving the conveyor belt 111 to move. Figure 4 When the tea placing mechanism 12 on the conveyor belt 111 moves from the descending section 1112 to the bottom of the conveyor belt 111, that is, the arc section where the conveyor belt 111 and the lower belt shaft 112 meet, the tea placing mechanism 12 gradually rotates 180 degrees around the lower belt shaft 112 and reaches the ascending section 1111. During this process, the tea placing structure 121, which was originally facing upward and holding a tea bag, becomes facing downward, causing the tea bag in the tea placing structure 121 to slide down. This movable range is denoted as the sliding discharge area 113. The sliding discharge area 113 is located below the descending section 1112. When passing through the sliding discharge area 113, the tea placing mechanism 12 rotates 180 degrees, enabling the tea bag to slide out. The empty tea placing mechanism 12 crosses the arc section at the bottom of the conveyor belt 111 and arrives on the left side, becoming the tea placing mechanism 12 on the ascending section 1111. The ascending section 1111 of the conveyor belt 111 drives the tea placing mechanism 12 thereon to move upward. Then, when the tea placing mechanism 12 crosses the arc section of the upper part of the conveyor belt 111 where the upper belt shaft 112 is in contact with the tea placing mechanism 12, the tea placing mechanism 12 will flip 180 degrees. During the flipping process of the tea placing mechanism 12, the tea bags in the tea placing mechanism 121 facing upward will move closer to the conveyor belt 111 and then fall onto the tea placing mechanism 121 facing upward on the descending section 1112. In other words, the tea bags are transferred from one tea placing mechanism 12 to another tea placing mechanism 12. Therefore, during the continuous movement of the conveyor belt 111, the tea bags on the tea placing mechanism 12 can be discharged one at a time. In this way, according to the required number of tea bags, the conveyor belt 111 can be controlled to move a specified stroke so that N tea placing mechanisms 12 pass through the sliding discharge area 113, thereby discharging N tea bags on the tea placing mechanisms 12.

[0154] join Figure 5 and Figure 8As a preferred design, the belt shaft 112 of the conveyor belt mechanism 1111 is horizontally arranged, that is, the angle between the belt shaft 112 and the horizontal plane is 0°. The angle between the conveyor positioning plane 114 in the conveyor belt mechanism and the vertical plane is 0. The ascending section 1111 and the descending section 1112 are located on both sides of the conveyor positioning plane 114 and are parallel to the conveyor positioning plane 114. In this case, the ascending section 1111 moves vertically upward, and the descending section 1112 moves vertically downward. This can better drive the movement of the tea placing mechanism 12 and complete the replacement and pouring of tea bags. Furthermore, the tea placing mechanism 12 can adopt a flat plate with flat surfaces on both sides, and tea bags can be placed thereon. That is, the tea placing structures 121 on both sides are mainly composed of a tea placing plane, which is parallel to the belt shaft 112, and the conveyor belt 1111 is perpendicular to the tea placing planes on both sides of the tea placing mechanism 12 when it is in a flattened state, so that the tea bags can be placed conveniently and stably. At this time, no enclosure is required around the tea placing plane, and the structure of the tea placing structure 121 is simple.

[0155] In other embodiments, the belt shaft 112 of the conveyor belt mechanism 1111 can also be tilted to a certain degree, and when the tilt angle between the belt shaft 112 and the horizontal plane is within 30 degrees, the corresponding functions can also be achieved. Its working principle is basically the same as when the belt shaft 112 is set horizontally. In this case, the linear motion directions of the rising section 1111 and the descending section 1112 of the conveyor belt 1111 are tilted. Similarly, the conveying positioning plane 114 where the axis lines of the two belt shafts 112 are located can also be tilted to a certain degree, and the angle between the belt shaft 112 and the vertical plane is within 60 degrees. The corresponding functions can also be achieved. In this case, the linear motion directions of the rising section 1111 and the descending section 1112 of the conveyor belt 1111 are tilted, and its working principle is basically the same as when the belt shaft 112 is set horizontally. When the ascending section 1111 and the descending section 1112 are inclined, the tea placing structure 121 of the tea placing mechanism 12 on the ascending section 1111 and the descending section 1112 can also be inclined at a certain angle. At this time, the tea placing structure 121 can be a accommodating box structure. For example, the tea placing structure 121 includes a tea placing plane and a circle of enclosure arranged around the tea placing plane to form a box-like structure, which can prevent the tea bag therein from slipping out due to the tilt of the tea placing structure 121.

[0156] In this embodiment, Figure 5 and Figure 8As a preferred design, the tea placing mechanisms 12 are evenly spaced along the extension direction of the conveyor belt 1111. The specific number of tea placing mechanisms 12 can be set according to actual needs, and the spacing L between adjacent tea placing mechanisms 12 is also set according to the number of tea bags. All tea placing mechanisms 12 are arranged along the extension direction of the endless conveyor belt 1111. Therefore, when controlling the output of tea bags, each movement of the conveyor belt 1111 by a distance L can complete the output of tea bags from one tea placing mechanism 12. To output N tea bags from the tea placing mechanisms 12, the conveyor belt 1111 is controlled to move a distance N*L. The control system is connected to the conveyor drive mechanism 13, and the control system controls the conveyor belt 1111 to automatically move a specific distance each time.

[0157] In this embodiment, Figure 5 、 Figure 8 and Figure 9As a preferred design, a pre-discharge inspection station is provided below the descending section 1112. As the descending section 1112 drives the tea placing mechanism 12 downward, it passes through the pre-discharge inspection station and then enters the sliding discharge area 113 below the descending section 1112. The teapot also includes a discharge inspection assembly 17, which includes a pre-discharge detector 172 disposed next to the pre-discharge inspection station. The pre-discharge detector 172 is capable of detecting tea bags on the tea placing mechanism 12 located at the pre-discharge inspection station. Since some tea placing mechanisms 12 may not have tea bags placed on them, that is, they are empty tea placing mechanisms 12, before controlling a tea placing mechanism 12 to move through the sliding discharge area 113, the pre-discharge detector 172 is first used to detect whether there is a tea bag on the tea placing mechanism 12, and the signal is fed back to the control system. If a tea bag is detected, the tea placing mechanism 12 can be recorded as a valid output. If no tea bag is detected, the tea placing mechanism 12 can be recorded as an empty output. The control system controls the conveyor belt 1111 to continue moving the stroke L to discharge the tea bag on the next tea placing mechanism 12. Furthermore, a post-discharge detection station is provided below the bottom of the conveyor belt 1111. The post-discharge detection station is located at the position of the sliding discharge area 113. The discharge detection assembly 17 includes a post-discharge detector 171, which can be specifically located at the rear side of the post-discharge detection station. The post-discharge detector 171 can detect the tea bag on the tea placing mechanism 12 located at the post-discharge detection station and feed back the signal to the control system to ensure whether the tea bag on the tea placing mechanism 12 slides down and is discharged smoothly, thereby monitoring whether the problem of unsuccessful discharge occurs due to the tea bag sticking to the tea placing mechanism 12 or getting stuck in the discharge position. The pre-discharge detector 172 and the post-discharge detector 171 can both use infrared or other photoelectric detectors. When the tea bag blocks its detection light, it can be detected by the pre-discharge detector 172 and the post-discharge detector 171. The pre-discharge detector 172 and the post-discharge detector 171 can specifically use existing mature detection products, and their working principles will not be described in detail. The pre-discharge detector 172 and the post-discharge detector 171 can also adopt the visual detection principle, by photographing the tea placing structure 121 and judging whether there is a tea bag inside. The visual detection principle can also adopt the existing design, and its working principle will not be described in detail.

[0158] In this embodiment, Figure 5 、 Figure 8 and Figure 9As a preferred design, a position calibration detector 16 is also included to calibrate the position of the tea placing mechanism 12 when the conveyor belt mechanism 1111 is stopped. When tea bags need to be added to the tea bag supply device 1, the conveyor belt mechanism 1111 is first controlled to move, driving the tea placing mechanism 12 to move. This allows one tea placing mechanism 12 to be detected by the position calibration detector 16, and the conveyor belt mechanism 1111 stops. This ensures that the number of tea placing mechanisms 12 located on the upper and lower arc sections of the conveyor belt 1111 is minimized, while the number of tea placing mechanisms 12 located on the ascending section 1111 and descending section 1112 is maximized. This ensures that as many tea placing mechanisms 12 as possible are in a horizontal position, facilitating the insertion of more tea bags. The specific position of the position calibration detector 16 is determined based on the spacing L between the tea placing mechanisms 12 and the diameter of the output shaft.

[0159] In this embodiment, Figure 5 、 Figure 6 and Figure 8 As a preferred design, it also includes a support frame 14 and a lifting and adjusting mechanism 15 installed on the support frame 14. The conveyor belt mechanism 1111 is installed on the support frame 14, and at least one belt shaft 112 is installed on the lifting and adjusting mechanism 15. The lifting and adjusting mechanism 15 can move the height position of the belt shaft 112 and stabilize it. The conveyor belt 1111 is ensured to remain taut by adjusting the height of the belt shaft 112. In this embodiment, specifically, the upper belt shaft 112 is rotatably installed on the support frame 14, the height position is fixed, and it is connected to the conveying drive mechanism 13 as the active shaft to drive the conveyor belt 1111 to move. The lower belt shaft 112 is a driven shaft, which is installed on the lifting and adjusting mechanism 15 and can adjust the upper and lower positions.

[0160] In this embodiment, Figure 5 、 Figure 6 and Figure 8As a preferred design, the lifting adjustment mechanism 15 includes a slider 152, a lifting adjustment block 151, and a locking assembly. The slider 152 and the lifting adjustment block 151 are both mounted on the support frame 14 and can move up and down in a direction parallel to the conveying positioning plane 114 and perpendicular to the belt shaft 112 (i.e., vertically in this embodiment). The locking assembly can lock the lifting adjustment block 151 to the support frame 14; the two ends of the belt shaft 112 are respectively mounted on the slider 152 and the lifting adjustment block 151. The lifting adjustment block 151 is provided with a vertically extending strip hole 1511, and the locking assembly includes a locking bolt (not shown in the drawings) that passes through the strip hole 1511 and is screwed to the support frame 14. When the height needs to be adjusted, loosen the locking bolt to release the locking fixation of the lifting adjustment block 151. At this time, the lifting adjustment block 151 can be moved up and down, and the locking bolt slides up and down in the bar hole 1511. The lifting adjustment block 151 drives the belt shaft 112 to move up and down, and the slider 152 also slides up and down. After the height adjustment is completed, tighten the locking bolt and fix the lifting adjustment block 151 on the support frame 14. The lifting adjustment mechanism 15 can easily adjust and stabilize the position of the belt shaft 112. In other embodiments, the locking component can also adopt other existing suitable structures, such as a circular hole + spring locating pin. In addition, the lifting adjustment mechanism 15 as a whole can also adopt other existing suitable structures.

[0161] In this embodiment, Figure 5 and Figure 6 As a preferred design, the conveying drive mechanism 13 includes a motor, which is directly or through an intermediate transmission structure connected to the upper belt shaft 112 in the conveyor belt mechanism 1111, and can well control the rotation angle of the belt shaft 112, and accurately control the movement stroke of the conveyor belt 1111. In this embodiment, the conveyor belt mechanism 1111 can adopt an existing conventional structure, and the two belt shafts 112 play the role of supporting the conveyor belt 1111, and the upper belt shaft 112 serves as a driving shaft for driving the conveyor belt 1111. The lower belt shaft 112 can rotate and serve as a driven shaft, and the lower belt shaft 112 can also not rotate. Depending on the axial length, the belt shaft 112 can also be called a pulley in some occasions, and the two are essentially the same.

[0162] In this embodiment, see Figure 5 and Figure 9 As a preferred design, the tea bag ...

[0163] In this embodiment, see Figure 5 and Figure 9As a preferred design, it also includes a hatch panel 18 disposed below the bottom of the conveyor belt mechanism 111, and a hatch opening and closing mechanism 19 that drives the hatch panel 18 to flip up and down. The hatch panel 18 is disposed at the discharge port, and the operation of the hatch opening and closing mechanism 19 is controlled by a control system. When the hatch opening and closing mechanism 19 drives the hatch panel 18 to a horizontal position, the hatch panel 18 blocks the discharge port. At this time, the hatch is closed. Tea bags that slide off the inclined storage mechanism 12 will land on the hatch panel 18, preventing misoperation and incorrect discharge. When the hatch opening and closing mechanism 19 drives the hatch panel 18 to flip downward, preferably to a certain tilt angle, the hatch is open. Tea bags that slide off the inclined storage mechanism 12 will fall through the discharge port and onto the hatch panel 18. They will then slide down along the inclined hatch panel 18 and finally fall. At this time, the hatch panel 18 also serves as a buffer transition and guide. The hatch opening and closing mechanism 19 includes a motor, and the motor output shaft is connected to the hatch plate 18 for driving the hatch plate 18 to flip. The hatch opening and closing mechanism 19 can also adopt other suitable designs to drive the hatch plate 18 to flip up and down.

[0164] In this embodiment, see Figure 5 and Figure 9 Furthermore, the hatch opening and closing mechanism 19 includes two position detectors 191 for detecting the position of the hatch panel 18. One position detector 191 detects when the hatch panel 18 rotates to the hatch-door closed position, while the other position detector 191 detects when the hatch panel 18 rotates to the hatch-door open position. This ensures automatic detection and control of the position of the hatch panel 18. The position detectors 191 can be conventional contact or non-release position switches. They can directly detect the hatch panel 18 or detect a detection plate fixed to the hatch panel 18. When material feeding is not in progress, the position detectors 191 signal is used to determine whether the hatch panel 18 has rotated to the hatch-door closed position. When material feeding is required, the hatch panel 18 is first controlled to rotate. The position detectors 191 signal ensures that the hatch panel 18 stops rotating when it reaches the hatch-door open position. This signal then activates the conveyor drive mechanism 13 to drive the conveyor belt mechanism 1111.

[0165] join Figure 1 and Figure 2 As a preferred design, the automatic tea making machine is provided with a plurality of tea bag supply devices 1, each tea bag supply device 1 can store different types of tea bags. According to the needs of tea making, the type of tea bag is determined and the corresponding tea bag supply device 1 is selected to output the tea bag.

[0166] Tea brewing device 2:

[0167] See also Figures 10 to 14, is a schematic diagram of the structure of the tea brewing device 2 in this embodiment. In this embodiment, the tea brewing device 2 includes a teapot 21, a tea bag dewatering basket 23, a basket movement mechanism 24, a tea bag pressing member 25, and a tea draining mechanism 27. The tea bag dewatering basket 23 is capable of holding tea bags. The basket movement mechanism 24 is connected to the tea bag dewatering basket 23 and is capable of driving the tea bag dewatering basket 23 to move. The tea bag dewatering basket 23 has two movable positions: a tea brewing position within the teapot 21, a pouring position outside the teapot 21, and a tea receiving position. When in the pouring position, the tea bag dewatering basket 23 can pour out the tea bags therein. When in the tea receiving position, the tea bag dewatering basket 23 can receive tea bags dropped from the tea bag supply device 1. The tea receiving position and the tea brewing position may overlap. The tea bag pressing member 25 can move to extend into the teapot 21 and press the tea bags in the tea bag dewatering basket 23 in the tea brewing position. The movement of the tea bag press 25 can be actively driven or passively driven. Specifically, a driving mechanism can be set to actively drive the tea bag press 25 to move. After the tea bag water filter basket 23 moves to the tea brewing position, the tea bag press 25 is driven by the driving mechanism to move and enter the tea bag water filter basket 23; the tea bag press 25 can also establish a linked movement with the tea bag water filter basket 23. When the tea bag water filter basket 23 moves to the tea brewing position, the tea bag press 25 moves with the tea bag water filter basket 23 and enters the tea bag water filter basket 23; the hot water supply device 4 is connected to the teapot 21; and the soup discharge mechanism 27 is connected to the teapot 21.

[0168] The main operating principle of the tea brewing device 2 is as follows: the tea bag dewatering basket 23 is a mesh structure with an internal storage space and an inlet and outlet for inserting and removing tea bags. When tea is brewed, the basket movement mechanism 24 moves the tea bag dewatering basket 23 to a tea receiving position, preferably coinciding with the tea brewing position. At this point, the tea bag dewatering basket 23 has entered the teapot 21, with the inlet and outlet facing upward and located below the output position of the tea bag supply device 1 (i.e., the hatch panel 18). The tea bag falls into the tea bag dewatering basket 23. The hot water supply device 4 is then controlled to inject hot water into the teapot 21. The hot water enters the tea bag dewatering basket 23 through the mesh and soaks the tea bag. The tea bag pressing member 25 extends into the teapot 21 and presses the tea bag in the tea bag dewatering basket 23 in the tea brewing position, preventing it from floating on the water surface. The tea bag pressing member 25 can extend through the inlet and outlet of the tea bag filter basket 23, pressing the tea bag in the tea bag filter basket 23 downward to prevent it from floating on the water surface. The tea bag pressing member 25 can also block the inlet and outlet of the tea bag filter basket 23 when in the tea brewing position. During tea brewing, the hot water will not cover the inlet and outlet of the tea bag filter basket 23, thus pressing the tea bag and preventing it from floating on the water surface. The tea bag pressing member 25 ensures a good tea brewing effect. The tea bag pressing member 25 can enter the teapot 21 and press the tea bag before, during, or after adding hot water. After the tea brewing time is complete, the tea bag needs to be discharged. The basket movement mechanism 24 drives the tea bag filter basket 23 to move, causing it to leave the teapot 21 and reach the dumping position. Before or during the movement of the tea bag strainer 23, the tea bag pressing member 25 can preferably be moved away from the interior of the teapot 21, without interfering with the movement of the tea bag strainer 23 into and out of the teapot 21 or the emptying of tea bags from the tea bag strainer 23. In the emptying position, the tea bag strainer 23 is tilted with its inlet and outlet facing downward, allowing for smooth emptying of any remaining tea bags. The tea in the teapot 21 is then drained by the drain mechanism 27 and sent to the tea cooling device 3.

[0169] In this embodiment, see Figure 10 、 Figure 12 and Figure 14 As a preferred design, the tea brewing device 2 also includes a cylinder cover 22. When brewing tea, the cylinder cover 22 covers the upper end of the teacup 21, thereby achieving a simmering and good tea brewing effect. The tea bag pressing piece 25 is installed on the cylinder cover 22 and is used to face the inner side of the teacup 21. It moves with the movement of the cylinder cover 22. When the cylinder cover 22 covers the upper end of the teacup 21, the tea bag pressing piece 25 extends into the teacup 21 and is inserted into the tea bag water filter basket 23 located at the tea brewing position, or is blocked at the inlet and outlet of the tea bag water filter basket 23. After the cylinder cover 22 leaves the upper end of the teacup 21, it drives the tea bag pressing piece 25 out of the teacup 21. With the above arrangement, the movement of the tea bag pressing piece 25 can be driven only by the movement of the cylinder cover 22, which can simplify the mechanism and operation process.

[0170] In this embodiment, see Figure 10 、 Figure 12 and Figure 14 As a preferred design, the cylinder cover 22 adopts a passive drive mode that moves with the movement of the tea bag water filter basket 23. The cylinder cover 22 is rotatably connected to the tea cup 21. When it is flipped upward, it can open the upper end of the tea cup 21. When it is flipped downward, it can cover the upper end of the tea cup 21. When the tea bag water filter basket 23 is in the tilted position, the cylinder cover 22 is in a tilted state, and the tea bag pressing piece 25 rests on the tea bag water filter basket 23. Figure 12 In the illustrated state, the tea bag dewatering basket 23, tea bag pressure piece 25, and lid 22 are all at appropriate tilt angles. As the tea bag dewatering basket 23 tilts downward into the teapot 21, the lid 22 and its tea bag pressure piece 25 tilt downward under the force of gravity. When the tea bag dewatering basket 23 is in the tea brewing position, the lid 22 precisely covers the upper opening of the teapot 21, while the tea bag pressure piece 25 enters the tea bag dewatering basket 23 through the basket inlet and outlet. After brewing is complete, the tea bag dewatering basket 23 tilts upward, simultaneously supporting the tea bag pressure piece 25 and lid 22, until it reaches the tilted position. Furthermore, the contact surface of the tea bag pressing member 25 with the tea bag dewatering basket 23 during rotation has a smooth transition, and can be configured as an arcuate surface, or a composite shape of an arcuate surface and a flat surface. Similarly, the outer surface of the tea bag dewatering basket 23 where it contacts the tea bag pressing member 25 during rotation also has a smooth transition, preferably configured as an arcuate surface, or a composite shape of an arcuate surface and a flat surface, thereby reducing friction between the tea bag dewatering basket 23 and the tea bag pressing member 25. With this approach, the movement of the cylinder cover 22 and the tea bag pressing member 25 can be achieved automatically without the need for an additional drive mechanism, requiring only the tea bag dewatering basket 23 to move, thereby simplifying the structure and operational control process.

[0171] In this embodiment, see Figure 10 、 Figure 12 and Figure 14Furthermore, one side of the tea bag pressing member 25 is rotatably connected to the inner side of the cylinder lid 22. When the tea bag dewatering basket 23 is in the tilted position, the cylinder lid 22 is tilted, and the tea bag pressing member 25 rests against the tea bag dewatering basket 23. As the tea bag dewatering basket 23 begins to rotate downward into the teapot 21, the tea bag pressing member 25 remains against the tea bag dewatering basket 23. Simultaneously, the inner side of the cylinder lid 22 abuts against the tea bag pressing member 25, causing both to tilt downward synchronously. When the cylinder lid 22 covers the upper end of the teapot 21, it ceases movement. However, under the action of gravity, the tea bag pressing member 25 can further rotate downward relative to the cylinder lid 22 a certain distance, thereby further pressing the tea bag downward. As the tea bag dewatering basket 23 tilts upward, it pushes against the tea bag pressing member 25, causing both the tea bag pressing member 25 and the cylinder lid 22 to rotate upward. In other embodiments, the tea bag pressing piece 25 can also be fixedly installed on the cylinder cover 22 to always maintain synchronous rotation. Correspondingly, the inner side surface of the cylinder cover 22 can also be abutted against the tea bag water filter basket 23 to achieve the movement effect of the tea bag water filter basket 23 driving the cylinder cover 22 and the tea bag pressing piece 25.

[0172] In other embodiments, the cover 22 may be actively driven, with a drive mechanism connected to the cover 22. The drive mechanism may comprise a motor and a reducer assembly 245, connected to the cover 22 via an intermediate transmission structure, thereby driving the cover 22 to rotate and, in turn, the tea bag pressing member 25 to automatically close and open the cover. In this manner, the cover 22 is first flipped over to open the cover before the tea bag strainer 23 rotates to pour the tea bags. During tea brewing, after the tea bag strainer 23 enters the teapot 21, the cover 22 is flipped over to close the cover.

[0173] In this embodiment, see Figure 10 、 Figure 12 and Figure 14 Furthermore, a pouring guide plate 231 is provided on one side of the tea bag dewatering net basket 23, while the remaining surfaces are a grid structure, collectively forming a net basket structure. When the tea bag dewatering net basket 23 is in the tea brewing position, the pouring guide plate 231 is located below and to the side of the tea bag dewatering net basket 23, and the pouring guide plate 231 is tilted. At this time, the tea bags in the tea bag dewatering net basket 23 will enter the pouring guide plate 231 and slide down along the pouring guide plate 231, thereby more smoothly pouring out the tea bags. Furthermore, the bottom end of the pouring guide plate 231 extends to the very bottom of the tea bag dewatering net basket 23 and is provided with multiple holes at the very bottom. The top end of the pouring guide plate 231 extends beyond the inlet and outlet of the tea bag dewatering net basket 23, thereby better guiding the tea bags to slide out.

[0174] In this embodiment, see Figure 10 、 Figure 12 and Figure 14As a preferred design, the tea bag presser 25 is a thin plate structure. Its width is slightly smaller than the width of the inlet and outlet of the tea bag strainer 23, and slightly smaller than the width of the inner cavity of the tea bag strainer 23. This ensures that the tea bag is more securely pressed and prevents it from floating through the gap in the width direction. Furthermore, a water-permeable opening is provided in the middle of the tea bag presser 25 to reduce resistance when the tea bag presser 25 moves up and down in hot water.

[0175] In this embodiment, see Figure 10 and Figure 14 As a preferred design, the tea brewing device 2 also includes a cleaning water injection mechanism, which is mounted on the teapot 21 and is capable of injecting cleaning water into the teapot 21. The cleaning water injection mechanism includes a cleaning water inlet frame 26 mounted on the upper end of the teapot 21. A water channel is provided within the cleaning water inlet frame 26. A cleaning water outlet 262 is provided on the inner side of the cleaning water inlet frame 26, communicating with the water inlet channel and located above the upper end of the teapot 21. A cleaning water inlet pipe 261 is also connected to the outer side of the cleaning water inlet frame 26, communicating with the water channel. Multiple cleaning water outlets 262 are arranged at different locations along the edge of the upper end of the teapot 21. Specifically, in this embodiment, the upper end of the teapot 21 is square. The cleaning water inlet frame 26 can be a U-shaped frame or a quadrilateral frame. Frame beams 264 are provided on three or four sides of the upper end of the teapot 21, each of which is provided with multiple cleaning water outlets 262. During use, the cleaning water inlet pipe 261 is connected to the cleaning water supply mechanism. Cleaning water enters the water channel within the cleaning water inlet frame 26 through the cleaning water inlet pipe 261, then flows out of the various cleaning water outlets 262 and falls into the teapot 21, effectively cleaning the interior of the teapot 21, as well as the tea bag filter basket 23 and tea bag press 25 located therein. Furthermore, the cleaning water outlets 262 located on opposite sides of the upper end of the teapot 21 are staggered relative to each other, that is, the cleaning water outlet 262 on one side is located between the two cleaning water outlets 262 on the opposite side. This staggered arrangement prevents convection and counteraction between the cleaning water outlets 262 on both sides, and also allows for staggered flushing. In other embodiments, the cleaning water injection mechanism can also adopt an existing suitable mechanism that can inject cleaning water into the teapot 21.

[0176] In this embodiment, see Figure 10 and Figure 14Furthermore, two guide side plates 263 are arranged opposite to each other at the upper end of the cleaning water inlet frame 26. The two guide side plates 263 are respectively arranged on the left and right sides of the upper end of the cylinder mouth of the teapot 21. The width of the space between the two guide side plates 263 gradually decreases from top to bottom, forming a trapezoidal gathering space with a larger top and a smaller bottom. The tea bag water filtering net basket 23 and the cylinder cover 22 are respectively rotatably connected to the front and rear sides of the upper end of the cylinder mouth of the teapot 21. The upper end width of the trapezoidal gathering space between the two guide side plates 263 is larger than the width of the tea bag water filtering net basket 23 and the cylinder cover 22 in the left and right directions. When the tea bag water filtering net basket 23 and the cylinder cover 22 rotate to enter the teapot 21, they will first enter between the two guide side plates 263. The two guide side plates 263 can play a guiding role to avoid the tea bag water filtering net basket 23 and the cylinder cover 22 from being offset in the left and right directions and causing collision problems.

[0177] In this embodiment, see Figure 10 and Figure 12 As a preferred design, the tea draining mechanism 27 includes a drain pipe 271 connected to the bottom of the teapot 21 and a drain control valve 272 disposed on the drain pipe 271. The control system is connected to the drain control valve 272. By controlling the opening and closing of the drain control valve 272, the tea in the teapot 21 can be automatically drained. The drain pipe 271 is connected to the tea cooling device 3 via a pipeline, and the hot tea is delivered to the tea cooling device 3. In other embodiments, the draining mechanism 27 may also adopt other suitable mechanisms.

[0178] In this embodiment, see Figure 10 、 Figure 12 and Figure 13 As a preferred design, the basket movement mechanism 24 includes a swing arm 241, a rotating shaft 242, and a rotating drive assembly. The rotating shaft 242 is rotatably mounted on the teapot 21 and is in a horizontal position. The two ends of the swing arm 241 are fixedly connected to the rotating shaft 242 and the tea bag water filter basket 23, respectively. The rotating drive assembly is connected to the rotating shaft 242. The rotating drive assembly includes a driven gear 243 coaxially fixed to the rotating shaft 242, a driving gear 244 meshing with the driven gear 243, and a motor and reducer assembly 245 connected to the driving gear 244. The motor and reducer assembly 245 drives the driving gear 244 and the driven gear 243 to rotate, further driving the rotating shaft 242 and the swing arm 241 to rotate, thereby driving the basket movement mechanism 24 to rotate about the rotating shaft 242, allowing the basket movement mechanism 24 to enter the teapot 21 more smoothly. In other embodiments, the net basket movement mechanism 24 may also adopt other existing suitable mechanisms, and the tea bag water filter net basket 23 may also have other movement trajectories. In addition to the flipping movement, it can also enter and exit the teacup 21 by lifting and lowering, and then perform a flipping movement outside the teacup 21.

[0179] In this embodiment, see Figure 10 and Figure 13 As a preferred design, the teapot 21 is equipped with a hot water inlet pipe 211, which is connected to the hot water supply device 4 to inject hot water into the teapot 21. A shower head 28 for hot water injection is provided in the teapot 21. The shower head 28 is connected to the hot water inlet pipe 211 and can disperse the injected hot water evenly onto the tea bag while preventing splashing. The hot teapot 21 is also equipped with various sensors, including temperature sensors and liquid level sensors, to monitor the teapot 21 during tea brewing and dispensing, enabling intelligent monitoring.

[0180] In this embodiment, the automatic tea brewing machine's control system is connected to the basket motion mechanism 24, thereby controlling the automatic movement of the basket motion mechanism 24 and, consequently, the movement of the tea bag strainer basket 23 according to a set time and trajectory. The control system is also connected to various detectors within the tea brewing device 2, receiving detection signals and performing corresponding actions based on these signals, thus achieving intelligent control. This control system enables the intelligent and automatic operation of the tea brewing device 2.

[0181] In this embodiment, as a preferred design, there are multiple tea brewing devices 2, the same number as the tea bag supply devices 1, and they correspond one to one and work in conjunction with each other. Each tea brewing device 2 receives tea bags from the corresponding tea bag supply device 1 to brew tea. In other embodiments, one tea brewing device 2 may correspond to multiple tea bag supply devices 1.

[0182] Tea cooling device 3:

[0183] See also Figures 15 to 18 , which is a schematic diagram of the structure of the tea soup cooling device 3 in this embodiment. In this embodiment, the tea soup cooling device 3 includes a cooling box 31 and a tea soup circulation coil 32. The cooling box 31 has a cooling working chamber containing a cooling medium. The cooling box 31 is provided with a tea soup inlet pipe 311 and a tea soup outlet pipe 312. The tea soup inlet pipe 311 is used to receive tea soup discharged from the tea brewing device 2. The tea soup circulation coil 32 is disposed in the cooling working chamber of the cooling box 31 and contacts the cooling medium. The tea soup circulation coil 32 extends in a curved manner, with its ends connected to the tea soup inlet pipe 311 and the tea soup outlet pipe 312, respectively.

[0184] The tea cooling device 3 is used to cool the hot tea discharged from the tea brewing device 2. During operation, the cooling medium in the cooling chamber of the cooling box 31 is preferably a liquid medium such as water, which provides a good cooling effect. Alternatively, a gaseous medium such as cooling air can be used. The low temperature of the cooling medium can be achieved by a cooling component within the cooling box 31 itself, such as a refrigerator with built-in refrigeration. Alternatively, the cooling medium can be provided externally and input into the cooling chamber of the cooling box 31. The hot tea enters the tea circulation coil 32 through the tea inlet pipe 311 and exchanges heat with the cooling medium through the pipe wall. Because the tea circulation coil 32 is curved and extends for a long length within the cooling box 31, the flow rate of the tea in the tea circulation coil 32 is slowed and the path is long. Therefore, the hot tea is fully cooled while flowing through the tea circulation coil 32 and is promptly discharged through the tea outlet pipe 312. This provides excellent cooling effect and high efficiency, enabling continuous cooling of large quantities of hot tea.

[0185] See also Figure 15 and Figure 17 In this embodiment, as a preferred design, the tea soup cooling device 3 further includes a liquid mixing mechanism 34 comprising a tea soup connection pipe 346, a purified water connection pipe 346, and an output connection pipe 348. The tea soup connection pipe 346 is used to receive the tea soup to be cooled and is specifically connected to the tea soup discharge pipe 271 of the tea brewing device 2 via a pipeline. The purified water connection pipe 346 is used to receive cold purified water, and the output connection pipe 348 is connected to the tea soup inlet pipe 311. The liquid mixing mechanism 34 is capable of mixing the delivered tea soup and purified water and outputting the mixed tea soup through the output connection pipe 348. During cooling operation, hot tea soup enters the tea soup connection pipe 346, which is connected to the purified water supply device 6 in the automatic tea brewing machine. The cold purified water and hot tea soup provided by the purified water supply device 6 are mixed in the liquid mixing mechanism 34, promptly performing the first stage of cooling of the tea soup, preserving the original taste as much as possible. The tea soup then enters the tea soup circulation coil 32 for further cooling, thereby improving the cooling effect.

[0186] See also Figure 15 and Figure 17In this embodiment, as a preferred design, the liquid mixing mechanism 34 includes a clean water delivery pump 341, a clean water flow meter 342, a tea soup delivery pump 343, a tea soup detector 344, and a mixing tee 345. The mixing tee 345 has three outlets. A clean water connection pipe 346 is connected to the first outlet of the mixing tee 345. The clean water delivery pump 341 and the clean water flow meter 342 are disposed on the clean water connection pipe 346. The tea soup connection pipe 346 is connected to the second outlet of the mixing tee 345. The tea soup delivery pump 343 and the tea soup detector 344 are disposed on the tea soup connection pipe 346. The third outlet of the mixing tee 345 is connected to the output connection pipe 348. The clean water delivery pump 341 is used to pump clean water. The clean water flow meter 342 monitors the clean water flow rate and controls the delivery volume of the clean water delivery pump 4 accordingly. The tea soup delivery pump 343 is used to pump hot tea soup, and uses the tea soup detector 344 to detect whether tea soup is flowing through the tea soup pipe 346, thereby determining whether the tea soup input has stopped, and starting and stopping the input of purified water according to the signal.

[0187] See also Figure 15 and Figure 16 In this embodiment, as a preferred design, the cooling chamber of the cooling box 31 is equipped with multiple independent tea soup circulation coils 32. The cooling box 31 is provided with multiple tea soup inlet pipes 311 and multiple tea soup outlet pipes 312. Each tea soup circulation coil 32 is connected to a tea soup inlet pipe 311 and a tea soup outlet pipe 312. Each tea soup circulation coil 32 is connected to a mixing mechanism 34. Each tea soup circulation coil 32 and mixing mechanism 34 operate independently. Each mixing mechanism 34 is connected to a tea brewing device 2 and works in conjunction with it to cool the hot tea from each tea brewing device 2.

[0188] See also Figure 16 and Figure 18In this embodiment, as a preferred design, the tea soup circulation coil 32 is arranged in a spiral from top to bottom in the cooling working chamber of the cooling box 31, forming a cylindrical structure similar to a coil. This can effectively increase the length of the tea soup circulation coil 32 and improve the cooling effect. Multiple tea soup circulation coils 32 are arranged at intervals within the cooling box 31 and arranged in one or more rows. The tea soup circulation coil 32 is firmly installed in the cooling working chamber using a coil fixing mechanism 33. The tea soup circulation coil 32 can also adopt other bending extension methods. For example, it can also be arranged in a back-and-forth manner on a plane. Specifically, it includes multiple straight sections that are parallel to each other and located in the same plane, with arc-shaped transition sections between adjacent straight sections. The entire tea soup circulation coil 32 has a flat structure and is a planar coil. When arranged in the cooling working chamber of the cooling box 31, the planar tea soup circulation coil 32 can be arranged horizontally or vertically. Multiple tea soup circulation coils 32 are parallel to each other and arranged at intervals.

[0189] See also Figure 16 In this embodiment, as a preferred design, the cooling medium in the cooling box 31 is cooling water. The cooling box 31 is provided with an injection pipe 316 connected to the cooling working chamber for injecting the cooling medium into the cooling working chamber. The cooling box 31 is provided with a medium circulation inlet pipe 313 and a medium circulation outlet pipe 314, both of which are connected to the cooling working chamber. It also includes a circulation pump (not shown in the drawings) connected to both the medium circulation inlet pipe 313 and the medium circulation outlet pipe 314. When the tea soup circulation coil 32 is cooling the tea soup, the problem of inconsistent cooling medium temperature will occur in different locations. The closer to the tea soup circulation coil 32, the higher the temperature. The temperature unevenness problem is more obvious when only part of the tea soup circulation coil 32 is working. By circulating the cooling medium through the circulation pump, the cooling medium temperature can be made more uniform, and the cooling effect on the tea soup circulation coil 32 can be better. The cooling medium drawn from the cooling working chamber by the circulation pump then passes through the refrigeration equipment 10 (including the compressor, etc.), where it is cooled, and then returns to the cooling working chamber through the medium circulation inlet pipe 313, thereby achieving a constant temperature of the cooling medium in the cooling working chamber. Furthermore, in this embodiment, a partition 377 is provided between two adjacent tea soup circulation coils 32. Multiple partitions 377 are arranged to drain and spaced apart along the length of the cooling working chamber. The circulation inlet pipe 13 and the medium circulation outlet pipe 314 are respectively provided on both sides of the cooling working chamber along the length direction, that is, the partitions 377 are both provided between the circulation inlet pipe 13 and the medium circulation outlet pipe 314. The partitions 377 can prevent the cooling medium from directly entering from the circulation inlet pipe 13 and flowing directly to the medium circulation outlet pipe 314. They can also increase the medium circulation distance, play a slowing role, and make the temperature of each area more uniform.

[0190] See also Figure 16In this embodiment, as a preferred design, a drain pipe 315 connected to the bottom of the cooling working chamber is provided at the bottom of the cooling box 31 for discharging the residual cooling medium or cleaning water inside the cooling working chamber. The cooling box 31 is also provided with an overflow port 317 connected to the cooling working chamber. When there is too much liquid cooling medium in the cooling working chamber, it flows out through the overflow port 317. The tea soup cooling device 3 also includes a medium temperature detector 35 and a medium liquid level detector 36 provided on the cooling box 31. The medium temperature detector 35 is used to monitor the temperature of the cooling medium in the cooling working chamber, and the medium liquid level detector 36 is used to monitor the liquid level of the liquid cooling medium in the cooling working chamber. When the cooling medium is injected into the cooling working chamber to a specified height, it can be detected by the medium liquid level detector 36 to avoid too little or too much cooling medium.

[0191] The control system is connected to the clean water delivery pump 341 and the tea soup delivery pump 343 of the mixing mechanism 34, thereby controlling the automatic operation of the mixing mechanism 34, and the control system receives detection signals from various detectors such as the clean water flow meter 342, the tea soup detector 344, the medium temperature detector 35 and the medium liquid level detector 36, thereby realizing automatic control and monitoring of the operation of the tea soup cooling device 3.

[0195] In this embodiment, the hot water supply device 4 monitors the water level in the hot water tank 41 during tea brewing. High and low level sensors 48 and 46 monitor the water level in the hot water tank 41. When the water level falls below a set value, the control system opens the water inlet control valve 44 to replenish the water. When the water level exceeds the set value, the control system closes the water inlet control valve 44, allowing excess water to drain from the hot water overflow port 49. The control system controls the heating mechanism 43 to heat the water in the hot water tank 41 according to tea brewing needs, and monitors the temperature via the hot water temperature sensor 47 to maintain the hot water at a specified temperature.
