Description

Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a brewing chamber structure and a capsule brewing machine. Background Technology

[0002] Dot matrix capsule beverage brewing machines are popular among users because they are more convenient and hygienic than manual brewing. The main reason why machine brewing is faster than manual brewing is that the brewing system formed by the machine and capsules applies pressure to the beverage ingredients placed inside the machine, promoting the extraction of beneficial substances. Pressurized brewing of capsule beverages is completed in the machine's brewing chamber. The brewing pressure of capsule beverages is mostly in the range of 3-12 bar. This requires the brewing chamber to have reliable pressure resistance. If the pressure resistance fails, there is a high possibility of the chamber bursting and leaking during brewing, causing hot water to splash, which poses a significant safety hazard.

[0063] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0064] like Figures 1 to 8As shown, this application provides a brewing chamber structure 100, including a main frame assembly 1, a sliding cover assembly 2, a capsule sealing chamber assembly 3, a motor assembly 4, and an electronic control assembly; the sliding cover assembly 2, the capsule sealing chamber assembly 3, and the motor assembly 4 are all mounted on the main frame assembly 1. The sliding cover assembly 2 includes a capsule dispensing port 221 and a sliding cover 21, which can slide in a horizontal direction to open and close the capsule dispensing port 221; the capsule sealing chamber assembly 3 includes a sealing chamber cover 31 and a sliding base 32 spaced apart, the sealing chamber cover 31... A brewing chamber is formed between the main frame assembly 1 and the capsule dispensing port 221; the sliding base 32 is provided with a receiving groove 321 for accommodating the capsule 200, the sealing chamber cover 31 is provided with a water inlet 312 that can communicate with the capsule 200, and the bottom of the receiving groove 321 is provided with a water outlet 323 that can communicate with the capsule 200; the motor assembly 4 is connected to the sliding base 32 and can drive the sliding base 32 to move horizontally in the brewing chamber toward the sealing chamber cover 31 to lock and seal the capsule 200;

[0065] The electronic control components include a main control electronic board, a micro switch, a magnetic induction switch, and a dot matrix recognition head 5. A magnet 211 that can cooperate with the magnetic induction switch is also provided on the sliding cover 21. The micro switch and the magnetic induction switch are used to detect the status of the sliding cover 21 and the motor assembly 4. The dot matrix recognition head 5 is located on the sealed compartment cover 31 and is used to identify the capsule 200. The main control electronic board can control the dot matrix recognition head 5 and the motor assembly 4 according to the signals from the micro switch and the magnetic induction switch.

[0066] Therefore, the brewing chamber structure 100 of this application utilizes the motor assembly 4 to move the sliding base 32, sealing and pressing the capsule 200 between the sliding base 32 and the sealing chamber cover 31. This provides a more reliable seal for the capsule 200, enabling both locking and easy opening of the brewing chamber. It achieves pressure-resistant, sealed brewing of the high-pressure capsule 200, preventing issues such as chamber bursting, leakage, and hot water splashing during brewing due to pressure-resistant measures failing. Simultaneously, through the cooperation of the main control electronic board, micro switch, magnetic induction switch, and dot matrix recognition head 5 in the electronic control assembly, not only can intelligent recognition of the capsule 200 be achieved, but the status of the sliding cover 21 and the motor assembly 4 can also be more accurately detected. This facilitates effective brewing of the high-pressure capsule 200, simultaneously satisfying the automated and intelligent recognition and brewing requirements of the capsule 200, and improving reliability.

[0067] Further optional, see Figure 7 and Figure 8The sliding cover assembly 2 also includes a sliding cover body located on top of the main frame assembly 1. The capsule dispensing port 221 is opened on the sliding cover body, and the sliding cover 21 is slidably mounted on the sliding cover body. A first micro switch 24 is provided on the sliding cover body, and a first magnetic induction switch 14 and a second magnetic induction switch 15 are provided on the main frame assembly 1. When the sliding cover 21 is in the fully open position, the sliding cover 21 can press the first micro switch 24 to make the first micro switch 24 open, and the magnet 211 can be located directly above the second magnetic induction switch 15. When the sliding cover 21 is in the fully closed position, the magnet 211 can be located directly above the first magnetic induction switch 14. The main control electronic board can activate the dot matrix recognition head 5 to identify the capsule 200 when the first micro switch 24 changes from the open state to the closed state and the second magnetic induction switch 15 changes from the open state to the closed state. It can also deactivate the dot matrix recognition head 5 and activate the motor assembly 4 when the first magnetic induction switch 14 changes from the closed state to the open state.

[0068] The sliding cover body is fixed to the main frame assembly 1. The first micro switch 24 is fixed to the sliding cover body. The magnet 211 is fixed to the inner side of the sliding cover 21 (i.e., the bottom surface of the sliding cover 21). The first magnetic induction switch 14 and the second magnetic induction switch 15 are both fixed to the main frame assembly 1. The second magnetic induction switch 15, the first magnetic induction switch 14, and the capsule dispensing port 221 are arranged sequentially at intervals along the aforementioned horizontal direction. The main control electronic board is electrically connected to the aforementioned first micro switch 24, first magnetic induction switch 14, second magnetic induction switch 15, dot matrix recognition head 5, and motor assembly 4. When the magnet 211 is directly above the magnetic induction switch, the magnetic induction switch is turned on; when the magnet 211 is away from the magnetic induction switch and no longer directly above it, the magnetic induction switch is turned off; the micro switch is turned on when it is pressed and turned off when it is released.

[0069] When the sliding cover 21 moves, the position of the sliding cover 21 can be determined by the different positional relationships between the magnet 211 and each magnetic induction switch and whether the first micro switch 24 is pressed. This allows the main control electronic board to control the dot matrix recognition head 5 and the motor assembly 4 based on the opening and closing states of the first micro switch 24 and each magnetic induction switch.

[0070] Optional, for ease of processing and installation, refer to Figure 1 and Figure 7The sliding cover body includes a sliding cover bracket 22 and a sliding cover top frame 23 fixed at the top and bottom, forming a sliding cover receiving cavity between them. The sliding cover bracket 22 is fixed to the top of the main frame assembly 1. The capsule dispensing port 221 is opened on the sliding cover bracket 22, and the sliding cover top frame 23 has an installation port 231 facing the capsule dispensing port 221. The length direction of the sliding cover body extends along the aforementioned horizontal direction. The shapes of the sliding cover top frame 23 and the sliding cover bracket 22 are matched. For example, both adopt a rectangular plate frame structure, the installation port 231 adopts a rectangular opening, the sliding cover 21 adopts a rectangular cover body, and the sliding cover receiving cavity is a rectangular cavity. The capsule dispensing port 221 and the sliding cover receiving cavity are spaced apart along this horizontal direction. The sliding cover 21 can be slidably inserted into the sliding cover receiving cavity. The head end of the sliding cover 21 extends out of the sliding cover receiving cavity, and the tail end of the sliding cover 21 is always located in the sliding cover receiving cavity. The aforementioned first micro switch 24 is fixed on the top surface of the sliding cover bracket 22. By manually sliding the sliding cover 21, the capsule dispensing port 221 can be opened or closed.

[0071] Further optional, see Figures 1 to 3 as well as Figure 6 The motor assembly 4 includes a motor 41, a gear pair structure, and two sets of linkage mechanisms 45 symmetrically arranged on both sides of the motor 41. The motor 41 is located inside the main frame assembly 1. The gear pair structure includes a meshing driving wheel 42 and a driven wheel 43. The driving wheel 42 is connected (fixed) to the output shaft of the motor 41. The driven wheel 43 is connected to the main frame assembly 1 through a gear transmission shaft 44. The first end of the linkage mechanism 45 is connected to the gear transmission shaft 44, and the second end of the linkage mechanism 45 is connected to the sliding base 32. The motor 41 can drive the driving wheel 42 to rotate, thereby driving the sliding base 32 to move in the horizontal direction.

[0072] Through the cooperation of motor 41, gear pair structure and linkage mechanism 45, the first end of linkage mechanism 45 is fixedly connected to gear transmission shaft 44, and the second end is lowerly connected to sliding base 32. By rotating the motor 41 forward or backward, the sliding base 32 moves closer to or further away from the sealing chamber cover 31, thereby locking or releasing capsule 200. Here, motor 41 can be, for example, a micro motor.

[0073] Specifically, refer to Figure 6 The connecting rod 452 structure includes a rocker arm 451 and a connecting rod 452. The first end of the rocker arm 451 is fixedly connected to the end of the gear drive shaft 44, and the second end of the rocker arm 451 is hinged to the first end of the connecting rod 452. The second end of the connecting rod 452 is hinged to the sliding base 32. The length of the connecting rod 452 is greater than the length of the rocker arm 451. Driven by the motor 41, the rocker arm 451 rotates and swings around the gear drive shaft 44, thereby driving the connecting rod 452 to pull the sliding base 32 to move back and forth in the horizontal direction.

[0074] Further optional, to facilitate the detection of the state of linkage 45, refer to Figures 1 to 3The active frame assembly is equipped with a second micro switch 16 and a third micro switch 17. The linkage mechanism 45 has a retracted position and an extended position. When the linkage mechanism 45 is in the extended position, the sliding base 32 is furthest from the sealing chamber cover 31 (at this time, the sliding base 32 abuts against the fixed seat 13 described below), and the linkage 452 can press the second micro switch 16 to make the second micro switch 16 open. When the linkage mechanism 45 is in the retracted position, the sliding base 32 can lock the capsule 200, and the linkage 452 can press the third micro switch 17 to make the third micro switch 17 open. The main control electronic board can control the motor 41 according to the state of the second micro switch 16 and the third micro switch 17.

[0075] When the sliding cover 21 is fully closed, the main control board controls the motor 41 to start and rotate forward, driving the sliding base 32 from the position furthest from the sealing chamber cover 31 towards the position closer to the sealing chamber cover 31. When the sliding base 32 moves to lock the capsule 200, the third micro switch 17 opens, and the main control board controls the motor 41 to stop. When the capsule 200 is brewed and the sliding cover 21 is fully open, the main control board controls the motor 41 to start and rotate, driving the sliding base 32 away from the sealing chamber cover 31. When the sliding base 32 moves to the position where the linkage mechanism 45 is extended, the second micro switch 16 opens, and the main control board controls the motor 41 to stop.

[0076] Furthermore, refer to Figure 2 and Figure 3 The second microswitch 16 and the third microswitch 17 are spaced apart in the horizontal direction, with the second microswitch 16 located between the sealing cover 31 and the third microswitch 17. A portion of the connecting rod 452 near its first end forms an upward-facing arc-shaped groove segment 4421. A protrusion 4422 is formed on the connecting rod 452, located between its second end and the arc-shaped groove segment 4421, and adjacent to the groove opening of the arc-shaped groove segment 4421. When the connecting rod mechanism 45 is in the extended position, the rocker arm 451 is in a horizontal state, with its second end located between its first end and the second end of the connecting rod 452, and the protrusion 4422 can press against the second microswitch 16. When the connecting rod 452 is in the retracted position, the rocker arm 451 is in a horizontal state, with its first end located between its second end and the second end of the connecting rod 452, the first end of the rocker arm 451 is engaged in the arc-shaped groove at the end of the arc-shaped groove, and the protrusion 4422 can press against the third microswitch 17.

[0077] Optionally, a limiting block 18 is also provided on the main frame assembly 1. When the linkage mechanism 45 is in the extended or retracted position, the limiting block 18 can abut against the linkage 452 to limit the movement of the linkage 452, so as to prevent the motor 41 from driving the linkage 452 to move when the linkage mechanism 45 is already in the extended or retracted position due to the failure of the second micro switch 16 or the third micro switch 17.

[0078] Optionally, the capsule 200 includes a cylindrical body and a guide ring disposed on the outer periphery of the cylindrical body. Two capsule grooves 19 are symmetrically arranged within the main frame assembly 1. The guide ring can slide along the two capsule grooves 19. The sliding base 32 can push the capsule 200 to seal against the sealing chamber cover 31 and disengage the guide ring from the capsule grooves 19. (Refer to...) Figure 2 Two capsule grooves 19 can be connected to both sides of the sealing chamber cover 31. The capsule grooves 19 can guide the capsule 200 and prevent the capsule 200 from being misaligned, which would affect the sealing and locking.

[0079] The cylindrical body can be cylindrical or conical. The shape of the capsule inlet 221 matches the shape of the longitudinal section of the capsule 200 along its axial direction. After fully opening the sliding cover 21, the capsule 200 is manually placed into the brewing chamber through the capsule inlet 221 and then inserted into the brewing chamber along the two capsule grooves 19. When the sliding base 32 moves towards the sealing chamber cover 31, the receiving groove 321 of the sliding base 32 fits onto the cylindrical body of the capsule 200, pushing the capsule 200 towards the sealing chamber cover 31 until the linkage mechanism 45 is in the retracted position, the capsule 200 is sealed and locked, and the guide ring is also forcibly disengaged from the capsule groove 19 under the pushing force of the sliding base 32.

[0080] It is understood that corresponding sealing rings are provided in both the sealing cover 31 and the fixing groove to ensure the sealing performance when the capsule 200 is locked. The specific structure of the capsule 200 can adopt any existing form. The two ends of the cylindrical body of the capsule 200 have sealing films, as shown in the figure. Figure 4 and Figure 5 A water inlet needle 311 is provided on the side of the sealed chamber cover 31 facing the sliding base 32, and a water outlet needle 322 is provided at the bottom of the receiving groove 321 of the sliding base 32. The water inlet needle 311 can communicate with the water inlet 312, and the water outlet needle 322 can communicate with the water outlet 323. When the capsule 200 is lowered into place along the capsule slide groove 19, the sliding base 32 moves closer to the sealed chamber cover 31, and the receiving groove 321 is fitted onto the cylindrical body. When the sliding base 32 seals and locks the capsule 200 against the sealed chamber cover 31, the water inlet needle 311 and the water outlet needle 322 pierce the sealing film at both ends of the capsule 200 respectively, realizing the conduction. The brewing water can enter the capsule 200 through the water inlet 312, and the brewed beverage fluid of the capsule 200 flows out through the water outlet 323.

[0081] Further optional, see Figure 2 and Figure 3The main frame assembly 1 includes a fixed horizontal plate 11 and a fixed base 13, as well as two side plates 12 arranged in parallel and spaced apart. The fixed horizontal plate 11 and the fixed base 13 are arranged at intervals in the horizontal direction. The fixed horizontal plate 11 is located at the first end of the two side plates 12, and the sealing chamber cover 31 is located at the second end of the two side plates 12. A plurality of sliding guide rods 33 are provided between the sealing chamber cover 31 and the fixed base 13, and the sliding base 32 is slidably sleeved on the plurality of sliding guide rods 33.

[0082] The fixed horizontal plate 11 and the fixed base 13 are arranged opposite each other at intervals. The surfaces of the fixed horizontal plate 11, the fixed base 13, and the two side plates 12 are all vertically arranged, and the surface of the side plates 12 is perpendicular to the surface of the fixed horizontal plate 11. The entire main frame assembly 1 roughly forms a rectangular frame. The two side plates 12 are fixed to the fixed horizontal plate 11 and the sealing chamber cover 31. Multiple sliding guide rods 33 are parallel to each other and arranged axially along the aforementioned horizontal direction. The two ends of the sliding guide rods 33 are fixedly connected to the sealing chamber cover 31 and the fixed base 13. The sliding base 32 is located between the sealing chamber cover 31 and the fixed base 13 and can reciprocate along the sliding guide rods 33 under the drive of the motor assembly 4. The area between the sealing chamber cover 31 and the fixed base 13 constitutes the aforementioned brewing chamber. The sliding guide rods 33 can be arranged according to... Figure 2 The diagram shows four sliding guide rods 33 connected to each side plate 12.

[0083] Reference Figure 3 The first magnetic induction switch 14 is installed (fixed) on the top of the sealed compartment cover 31, and the second magnetic induction switch 15 is installed (fixed) on the top of the fixed horizontal plate 11.

[0084] The aforementioned motor 41 is located between the two side plates 12. The housing of the motor 41 can be fixed to one of the side plates 12. The driven wheel 43 is sleeved and fixed on the gear drive shaft 44. Two through holes are opened on the two side plates 12. The axial direction of the gear drive shaft 44 is perpendicular to the aforementioned horizontal direction. The gear drive shaft 44 is located between the two side plates 12. Both ends of the gear drive shaft 44 pass through the two through holes and exit the two side plates 12, and are fixedly connected to the first ends of the two rocker arms 451. The second micro switch 16 and the third micro switch 17 are both fixed on one of the side plates 12. The aforementioned limiting block 18 is also fixed on the same side plate 12.

[0085] For more detailed information, please refer to the circuit control schematic of the brewing chamber structure 100. Figure 19 The working process of the brewing chamber structure 100 is as follows:

[0086] A. Manually open the sliding cover 21. When the sliding cover 21 is fully open, the first micro switch 24 is pressed and is in the open position, and the second magnetic induction switch 15 is in the open position. Manually insert the capsule 200 (such as a tea capsule) with a dot matrix identification code into the brewing chamber from the capsule inlet 221 along the capsule slide 19.

[0087] B. Manually begin closing the sliding cover 21. This triggers the first microswitch 24, causing it to change from a pressed state to a released state, thus closing the cover. Simultaneously, because the inner side of the tail end of the sliding cover 21 has a magnet 211, during the sliding closing process, the magnet 211 changes from an open state (facing the second magnetic induction switch 15) to an open state (moving away from the second magnetic induction switch 15). The changes in the first microswitch 24 and the second magnetic induction switch 15 are converted into electrical signals and transmitted to the main control electronic board. The main control electronic board then sends a command to activate the dot matrix recognition head 5 to begin recognizing the inserted capsule 200.

[0088] C. When the sliding cover 21 is completely closed, the first micro switch 24 and the second magnetic induction switch 15 are still in the completely closed state. At this time, the magnet 211 reaches the first magnetic induction switch 14 directly above the tail end of the sliding cover 21, triggering it to open. This change is transmitted to the main control electronic board through an electrical signal. The main control electronic board sends an instruction to control the dot matrix recognition head 5 to close. At this time, the capsule 200 has completed the recognition.

[0089] D. At the same time, the main control electronic board sends a command to the motor 41 to start rotating forward and lock the brewing chamber. The motor 41 drives the gear pair structure (driving wheel 42 and driven wheel 43) to rotate forward through its output shaft. The gear pair structure drives the rocker arm 451 in the linkage mechanism 45 (which is fixedly connected to the gear transmission shaft 44 and the driven wheel 43) to rotate forward (the rocker arm 451 and the connecting rod 452 are rotatably connected to form the linkage mechanism 45), thereby driving the connecting rod 452, which is rotatably connected to the rocker arm 451, to retract towards the sealing chamber cover 31.

[0090] E. The linkage mechanism 45 is rotatably connected to the sliding base 32. When the linkage mechanism 45 retracts, the sliding base 32 is pulled by the linkage 452 along the sliding guide rod 33 towards the sealing chamber cover 31. Until the linkage 452 and the rocker arm 451 are in a retracted and locked state, the protrusion 4422 on the linkage 452 presses against the third micro switch 17, causing the third micro switch 17 to open, and the limit block 18 abuts against the linkage 452 to form a limit. The third micro switch 17 sends an electrical signal to the main control electronic board, which then sends a command to the motor 41 to stop rotating forward. At this point, the brewing chamber is locked, and the capsule 200 is started for brewing.

[0091] F. After capsule 200 is brewed, manually open the sliding cover 21. During the opening of the sliding cover 21, the first magnetic induction switch 14 closes as the magnet 211 moves away; when the sliding cover 21 is fully opened, the second magnetic induction switch 15 opens as the magnet 211 moves closer, and simultaneously, the first micro switch 24 opens due to being pressed. The changes in the first magnetic induction switch 14, the second magnetic induction switch 15, and the first micro switch 24 are converted into electrical signals and transmitted to the main control electronic board. The main control electronic board then sends a command to control the motor 41 to start and reverse to open the brewing chamber.

[0092] G. When motor 41 reverses, it drives linkage mechanism 45 to unfold via gear pair structure. Linkage mechanism 45 pushes sliding base 32, which is rotatably connected to it, to move away from sealing chamber cover 31 along sliding guide rod 33 until linkage 452 unfolds to press the second micro switch 16. At this point, linkage mechanism 45 is fully unfolded, sliding base 32 is pushed into place, and brewing chamber is fully opened. At this time, the change of the second micro switch 16 is converted into an electrical signal and transmitted to the main control electronic board. The main control electronic board sends a command to motor 41 to stop flipping. After brewing, the waste capsule 200 falls into wastewater box 500 for recycling.

[0093] H. The entire brewing process is now complete.

[0094] Furthermore, refer to Figures 1 to 21 This application also provides a capsule brewing machine, comprising:

[0095] The main unit 300 has an opening 3021 on its top facing the capsule dispensing port 221, and a water outlet 303 on its side.

[0096] The aforementioned brewing chamber structure 100 is located at the top inside the main unit 300, and the water outlet 323 of the brewing chamber structure 100 can be connected to the water outlet 303.

[0097] The water tank 400 is located on the side of the main unit 300. The water tank 400 can be connected to the water inlet 312 of the brewing chamber structure 100 through the water pump 304 and the heating pot 305. The main control electronic board is electrically connected to the water pump 304 and the heating pot 305.

[0098] Wastewater box 500, located at the bottom of the main unit 300, is used to collect the discarded capsules 200 after brewing.

[0099] The capsule brewing machine uses the brewing chamber structure 100 described above and has the same advantages.

[0100] The aforementioned brewing chamber structure 100 is used to embed capsules 200 (such as tea capsules) and to identify and brew the capsules 200. It is a key component of the entire brewing machine. The entire brewing chamber structure 100 is fixed on the main unit bracket 301 of the main unit 300. The brewing chamber structure 100 enables pressure-resistant sealing and locking during high-pressure capsule brewing.

[0101] Reference Figures 9 to 11 The host 300 includes a host housing 302 and a host bracket 301 disposed within the host housing 302. The host 300 can be configured according to... Figure 9The main structure shown is roughly rectangular. The two side plates 12 and the mounting base 13 of the main frame assembly 1 are fixed to the main unit bracket 301 of the main unit 300. The water pump 304 and the heating element 305 are located inside the main unit 300. The outlet of the water pump 304 is connected to the inlet of the heating element 305 via corresponding pipes. The main control electronic board is also located inside the main unit 300 of the brewing machine. The opening 3021 is located on the top surface of the main unit housing 302, directly opposite the mounting opening 231 of the sliding cover top frame 23, facilitating manual opening and closing of the sliding cover 21 by the user. The water tank 400, mainly used for storing brewing water, is fixed to the side of the main unit housing 302.

[0102] Alternatively, a display screen 600 is provided on the side of the main unit 300. The main control electronic board is electrically connected to the display screen 600 to display the brewing progress of the capsules 200 and to allow users to control the brewing process. The display screen 600 can use existing touch technology for easy user operation. The screen of the display screen 600 can clearly display brewing information, allowing users to fully understand the brewing status.

[0103] Optionally, a water level sensor is installed inside the water tank 400, and the main control electronic board is electrically connected to the water level sensor to detect the water level in the water tank 400. When the water level in the water tank 400 is lower than the preset minimum water level, the main control electronic board controls the display screen 600 to display a water shortage warning to remind the user to add water.

[0104] Alternatively, a tea tray 700 is provided on the bottom side of the main unit 300, which is positioned directly opposite the water outlet 303. The tea tray 700 is used to place containers such as water cups.

[0105] Further optional, see Figure 10 and Figure 14 The main unit 300 is also equipped with a fan 306. The air outlet 3061 of the fan 306 is connected to the side air outlet 3022 of the main unit 300 and is located below the water outlet 303. The main control electronic board is electrically connected to the fan 306.

[0106] The aforementioned spout 303 is positioned downwards, with the display screen 600 located above it. The fan 306 is mounted on the main unit bracket 301. A long, narrow side air outlet 3022 is provided on the side of the main unit housing 302. The size and shape of the side air outlet 3022 match the air outlet 3061 of the fan 306. The air outlet 3061 of the fan 306 is directly opposite the side air outlet 3022, and the air outlet 3061 is positioned horizontally. The small fan 306 enables anti-fogging by blowing air through the air outlet 3061, dispersing the steam from the tea and preventing the display screen 600 from fogging up and becoming illegible.

[0107] Alternatively, an infrared sensor may be installed inside the wastewater box 500, and the main control electronic board may be electrically connected to the infrared sensor.

[0108] Infrared sensors can be used to detect the height of waste gas accumulation inside the wastewater box 500. When the height of the waste capsules 200 inside the wastewater box 500 reaches the preset height, the main control electronic board controls the display screen 600 to display a corresponding prompt based on the signal sent by the infrared sensor, so as to remind the user to clean the wastewater box 500.

[0109] Further optional, see Figure 11 as well as Figure 21 The main unit 300 is also equipped with an external water inlet 307. The water pump 304 can be connected to the water tank 400 or the external water inlet 307 through the first three-way solenoid valve. The main control electronic board is electrically connected to the first three-way solenoid valve.

[0110] The air outlet 3061, display screen 600 and water outlet 303 of the aforementioned fan 306 are all located on the same side (front) of the main unit 300. The external water inlet 307 can be located at the bottom of the other side (back) of the main unit 300, for example. The external water inlet 307 can be used to connect the external water outlet 308 to realize the external water inlet function.

[0111] Specifically, refer to Figure 16 , Figure 17 and Figure 20 An external water inlet 307 can be inserted into an external water nozzle 308. A fourth micro switch 3071 is provided on the external water inlet 307. The fourth micro switch 3071 is in the open state when the external water nozzle 308 is inserted into the external water inlet 307 and in the closed state when the external water nozzle 308 is pulled out of the external water inlet 307. The main control electronic board can control the first three-way solenoid valve according to the signal of the fourth micro switch 3071.

[0112] The main control electronic board is electrically connected to the fourth micro switch 3071. Depending on whether the external water nozzle 308 is inserted into the external water inlet 307 and whether the fourth micro switch 3071 is open, the active electronic board can control the first three-way solenoid valve to connect the water pump 304 to the external water nozzle 308 or to the water tank 400, so as to realize external water inlet or water supply from the water tank 400.

[0113] Alternatively, a flow meter is installed on the connecting pipeline between the first three-way solenoid valve and the water pump 304, and the main control electronic board is electrically connected to the flow meter to facilitate flow detection.

[0114] For more detailed information, please refer to the schematic diagram of the external water circuit on / off control. Figure 20 The external water connection control process is as follows:

[0115] A. When the external water nozzle 308 is inserted into the external water inlet 307 on the back of the main unit 300, the external water nozzle 308 presses the fourth micro switch 3071 to open it. This change is converted into an electrical signal and sent to the main control electronic board. The main control electronic board sends a command to the first three-way solenoid valve, and the external water inlet end of the first three-way solenoid valve (i.e., the port in the first three-way solenoid valve connected to the external water inlet 307) opens, while the water tank interface end (i.e., the port in the first three-way solenoid valve connected to the water tank 400) closes. At this time, the water inlet mode is external water inlet, and water inlet to the water tank 400 is disabled.

[0116] B. When the external water nozzle 308 is pulled out from the external water inlet 307 on the back of the main unit 300, the fourth micro switch 3071 changes from the pressed state to the released state and closes. This change is converted into an electrical signal and sent to the main control electronic board. The main control electronic board sends a command to the first three-way solenoid valve. The external water inlet end of the first three-way solenoid valve closes and the water tank interface end opens. At this time, the water inlet mode is water tank 400 water inlet, and the external water inlet is disabled.

[0117] Further optionally, the spout 303 includes a sleeve spout consisting of an inner ring tube and an outer ring tube. The outlet of the heating pot 305 can be connected to the inlet 312 of the brewing chamber or to a water outlet pipe through a second three-way solenoid valve. The main control electronic board is electrically connected to the second three-way solenoid valve. The water outlet pipe is connected to the outer ring tube, and the water outlet 323 of the brewing chamber can be connected to the inner ring tube.

[0118] The 303 spout uses a sleeve spout, with the inner ring tube for tea and the outer ring tube for water. The entire brewing mechanism is a dual system for tea and water, with the tea path and water path set up separately to prevent interference between them, resulting in an aesthetically pleasing design and no flavor mixing.

[0119] Alternatively, a check valve may be provided on the connection pipe between the outlet of the heating pot 305 and the second three-way solenoid valve, so that hot water flows only in the direction of the second three-way solenoid valve.

[0120] Further optional, see Figure 15 and Figure 21 The main unit 300 is also equipped with a water pump 309. The water outlet 303 can be connected to the water outlet 323 of the brewing chamber or the inlet of the water pump 309 through the third three-way solenoid valve. The main control electronic board is electrically connected to the third three-way solenoid valve. The outlet of the water pump 309 is connected to the wastewater box 500.

[0121] A small water pump 309 is installed on the main unit 300, which can be used to start water suction when the tea brewing is finished, so as to solve the problem of dripping water from the tea spout after the tea is finished.

[0122] For a more detailed schematic diagram of the entire water circuit, please refer to [link / reference]. Figure 21 The overall water circuit principle and flow are as follows:

[0123] A. The water tank 400 is connected to the external water nozzle 308 via a first three-way solenoid valve. When the external water nozzle 308 is not inserted into the external water inlet 307, that is, when it is not connected to the first three-way solenoid valve, the water tank interface end of the first three-way solenoid valve is open and the external water inlet end is closed. At this time, the water inlet method is water tank 400.

[0124] B. Water pump 304 starts. Water flowing from water tank 400 is pumped into water pump 304 through the first three-way solenoid valve and the flow meter (used to measure the water output to ensure the target output volume). After being heated, the hot water flows out of the heating pot 305 and through the one-way valve (function: to prevent hot water backflow) into the second three-way solenoid valve. When dispensing tea, the tea path outlet end of the second three-way solenoid valve (i.e., the port in the second three-way solenoid valve connected to the brewing chamber) opens, and the water path outlet end (i.e., the port in the second three-way solenoid valve connected to the water outlet pipe) closes. Hot water flows out from the tea path outlet end of the second three-way solenoid valve and enters the inlet 312 in the brewing chamber through the tea path pipe (i.e., the connecting pipe between the second three-way solenoid valve and the inlet 312 of the brewing chamber). It then enters the capsule 200 through the inlet needle 311 to brew the tea leaves inside the capsule 200. After brewing, the tea soup flows out of the capsule 200 through the water needle 322 and out of the water outlet 323 on the sliding base 32, and enters the third three-way solenoid valve.

[0125] C. One end of the third three-way solenoid valve is connected to the spout for dispensing tea or water, and is connected to the inner ring tube of the spout; the other end is connected to a small water pump 309 and the water outlet 323 of the brewing chamber. During normal tea dispensing, the end of the third three-way solenoid valve connected to the brewing chamber is open, and the end connected to the small water pump 309 is closed. The water outlet 303 (specifically, the inner ring tube) is connected to the outlet of the brewing chamber but not to the water pump 309. The tea flows from the tea outlet (the end of the inner ring tube) of the spout into the teacup below. When tea dispensing is complete, the end of the third three-way solenoid valve connected to the brewing chamber is closed, and the end connected to the small water pump 309 is open. The inner ring tube of the water outlet 303 is connected to the water pump 309 but not to the brewing chamber. The water pump 309 can then remove any remaining tea from the pipes and spout, preventing dripping after dispensing.

[0126] D. The entire tea-making process ends when the small water pump 309 finishes working.

[0127] E. When the external water nozzle 308 is inserted into the external water inlet 307, that is, when the first three-way solenoid valve is connected, the first three-way solenoid valve opens at the external water inlet end and closes at the water tank interface end. At this time, the water inlet method is external water inlet.

[0128] F. External water enters the first three-way solenoid valve 1 through the external water inlet 308, flows out of the first three-way solenoid valve, passes through the flow meter, and is pumped into the heating pot 305 by the water pump 304 for heating. Hot water enters the second three-way solenoid valve through the one-way valve. At this time, the water path end of the second three-way solenoid valve is open, and the tea path end is closed. The hot water flowing out of the water path end of the second three-way solenoid valve enters the water outlet end of the outer ring tube of the tea / water spout through the water outlet pipe, and flows out from the water outlet end into the water cup below. The dispensing of boiling water ends.

[0129] As an additional option, the main control board also integrates a WiFi module to enable the capsule brewing machine to connect to the cloud and communicate with WeChat mini-programs.

[0130] The device is connected to the cloud via WiFi and controlled via WeChat Mini Program. The cloud connection enables online upgrades of the device's parameters, while the WeChat Mini Program allows for control and status monitoring of the device.

[0131] Furthermore, for more specific details, please refer to the complete circuit control schematic diagram. Figures 18 to 20 The overall working process of the machine is as follows:

[0132] A. When brewing tea, place the water cup at the bottom of the tea / water spout 303 of the brewing machine, open the sliding cover 21, and put the tea capsule 200 into the brewing chamber through the capsule inlet 221.

[0133] B. Close the sliding cover 21, and the motor 41 will lock the brewing chamber.

[0134] C. At this point, capsule 200 has been recognized, and a successful recognition message will appear on display screen 600. The user touches the tea brewing function button on display screen 600 to start brewing tea. The brewing machine brews capsule 200 according to the matched parameters. The tea flows from the inner tube of the spout into the water cup below the spout.

[0135] D. At the same time, the small fan 306 starts working to blow air and disperse the mist from the brewed tea, preventing water vapor from adhering to the display screen 600 located directly above the spout 303 and making the display unclear.

[0136] E. Immediately after brewing, activate the small water pump 309 to draw out the remaining tea liquid and send it into the wastewater box 500 to avoid dripping from the tea spout after brewing.

[0137] F. When the small water pump 309 stops working, the brewing process of capsule 200 ends, and a brewing completion indicator will appear on the display screen 600. Manually open the sliding cover 21, and the motor 41 will open the brewing chamber. The used capsules 200 will fall into the wastewater box 500 below and be collected. The entire brewing process is now complete.

[0138] G. When the discarded capsules 200 accumulate to a predetermined height, the infrared sensor signal of the wastewater box 500 is triggered. This sends a command to the display screen 600 via the main control board, reminding the user to clean the wastewater box 500. The user manually removes the wastewater box 500 for cleaning. After cleaning, the wastewater box 500 is placed back into the brewing machine.

[0139] H. When boiling water, place the cup under the water spout 303 of the brewing machine and touch the water dispensing function button on the display screen 600. The brewing machine will then begin dispensing boiling water according to its built-in boiling water heating program. At the same time, the small fan 306 will start blowing air to disperse the steam. The small fan 306 will stop working once the water dispensing is complete.

[0140] In summary, this application not only achieves automated, pressure-resistant, and sealed brewing of tea capsules 200 through the combination of motor 41 and brewing chamber structure 100, but also realizes automated and convenient operation of the entire machine through identification functions and external water access detection functions. This solution is rationally designed and highly reliable. Furthermore, through dot matrix recognition functions, capsule brewing timeout reminders, water tank low water functions, wastewater box low water reminders, water-steam mixing and cleaning functions, water pump to remove residual tea, and small fan misting functions, the entire machine achieves intelligent and convenient brewing. In addition, the brewing machine of this invention has WiFi functionality, enabling cloud connection and WeChat mini-program control, improving the user experience. This invention is ingeniously designed, with a stable and reliable solution, and plays a promoting role in the development of small household appliances.

[0141] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
