Description

Technical Field

[0001] This application relates to the technical field of tea brewing equipment, specifically to an automatic cup-dropping and brewing mechanism. Background Technology

[0002] Brewing is a unique procedure in the tea-making process. Different types of tea require different brewing methods to bring out their full aroma and flavor. Tea brewing equipment is a specialized appliance for brewing tea, available in various types and functions to meet the needs of different users. Traditional tea brewing equipment commonly includes gaiwans and teapots. However, with continuous technological advancements, automatic brewing equipment has been developed for convenient tea drinks such as tea bags and capsules. Currently, most similar products on the market have manually openable and closed brewing mechanisms, or the identification and motor structures are separate. This requires scanning the external barcode of the capsule, opening the door, inserting the capsule, closing the door, and then closing the capsule compartment. This multi-step operation is not user-friendly or convenient.

[0003] Therefore, this application provides an automatic cup-dispensing and brewing mechanism to solve the above problems. Utility Model Content

[0004] This application provides an automatic cup-dropping and brewing mechanism, aiming to solve the problems mentioned in the background art. Currently, similar products on the market mostly require manual opening and closing of brewing mechanisms, or the identification is separated from the motor structure, requiring external scanning of the capsule product, opening the compartment door after scanning, inserting the capsule, closing the compartment door, and closing the capsule compartment. This requires multiple steps during use, and the human-computer interaction is not user-friendly or convenient.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic cup-dispensing and brewing mechanism, including a housing and a cup-dispensing and brewing mechanism fixedly installed inside the housing for brewing the original liquid in the tea bag capsule cup:

[0006] The cup-dropping brewing mechanism includes a fixed bracket fixedly installed inside the housing and a motor bracket fixedly installed at one end of the fixed bracket. A capsule chamber is fixedly installed on the fixed bracket, and a geared motor is fixedly installed on the motor bracket. A lead screw is fixedly installed through the motor bracket at the output end of the geared motor. A chamber door adapted to the capsule chamber and located below the capsule chamber is screwed onto the lead screw. A brewing chamber adapted to the capsule chamber is fixedly installed on the chamber door. A water inlet needle with its end facing into the brewing chamber is fixedly installed on the brewing chamber. A water outlet needle opposite to the water inlet needle is fixedly installed on the fixed bracket at the opposite end of the motor bracket. A guide groove adapted to the tea bag capsule cup is fixedly installed at the top position of the capsule chamber. A clamping block adapted to the guide groove is movably installed on the fixed bracket at the position below the guide groove. An infrared detection module is fixedly installed on one side of the guide groove on the fixed bracket, and an encoding recognition head is fixedly installed on one side of the infrared detection module. Thus, during brewing, the door is initially closed. The tea bag / capsule is placed into the capsule compartment, locking it into the guide groove. The coding and identification head then scans and identifies the invisible tag on the tea bag / capsule, while the infrared detection module checks the installation status. Once confirmed, the reduction motor is activated, driving the lead screw to rotate. The lead screw moves the door away from the capsule compartment, opening the bottom of the compartment and allowing the tea bag / capsule to fall from the guide groove onto the clamping block below. The reduction motor is then activated again, reversing the lead screw and retracting the door. This, in turn, moves the brewing chamber forward, pushing the tea bag / capsule towards the water outlet. The needle moves until the inlet and outlet needles pierce the tea bag capsule cup from both sides. Water is introduced through the inlet needle to brew the original liquid in the tea bag capsule cup, and then the tea flows out through the outlet needle, completing the automatic brewing process. After brewing, the reduction motor is restarted, which drives the chamber door to move backward, causing the inlet and outlet needles to detach from the tea bag capsule cup. This leaves the tea bag capsule cup unsupported, and it will automatically fall out from the bottom of the fixed support, completing the automatic detachment. The entire device integrates recognition and capsule dropping, and after placing the capsule, it can realize recognition + fully automatic capsule dropping + brewing + capsule disposal functions, improving the user experience and making operation convenient.

[0007] Preferably, for installing the tea bag capsule cup, a capsule mounting seat adapted to the capsule compartment is fixedly installed on the shell, and the capsule mounting seat protrudes from the plane of the shell. This ensures stable support for the tea bag capsule cup during installation and prevents it from rolling off.

[0008] Preferably, for use in brewing, a water inlet connector that communicates with the water inlet needle is fixedly installed on the brewing chamber. This allows for rapid brewing of the original liquid in the tea bag capsule cup, and the operation is simple.

[0009] Preferably, to facilitate the ejection of the tea bag capsule, the fixing bracket has a reset spring cavity adapted to the clamping block, and a reset spring that abuts against the clamping block is fixedly installed inside the reset spring cavity. This ensures a very stable separation of the water inlet needle from the tea bag capsule.

[0010] Preferably, to ensure the tea bag capsule cup detaches from the water outlet needle, the clamping block has a clamping cavity with an arc-shaped cross-section that matches the tea bag capsule cup. The groove depth on the side of the clamping cavity facing the water outlet needle is lower than the groove depth on the side away from the water outlet needle, and the side of the clamping cavity facing the water outlet needle has a gently sloping cross-section. This facilitates fixing or detaching the tea bag capsule cup and prevents it from getting stuck.

[0011] Preferably, for ease of maintenance, a flange is fixedly installed at the connection point between the end of the lead screw away from the geared motor and the compartment door. Connecting the lead screw to the compartment door via the flange facilitates disassembly and maintenance.

[0012] Preferably, to eject the tea bag capsule cup, a push rod extending towards the water inlet needle is inserted into the fixed bracket on the same side as the water outlet needle. A push spring is fixedly installed inside the fixed bracket between the push rod and the end of the push rod. This ensures that the tea bag capsule cup can smoothly detach from the water outlet needle.

[0013] Preferably, to ensure stable brewing, the fixed support is symmetrically provided with movable slots that adapt to the door and brewing chamber, and a position sensor is fixedly installed on one side of the movable slot on the fixed support to ensure stable operation of the equipment.

[0014] Preferably, to ensure a safe brewing environment, a sealing ring compatible with the tea bag capsule cup is fixedly installed on the side of the fixed bracket that is coplanar with the water outlet needle and faces the brewing cavity. This ensures that no leakage occurs when brewing the original liquid in the tea bag capsule cup, guaranteeing a smooth brewing process.

[0015] The brewing mechanism starts with the door closed. When a tea bag / capsule is placed into the capsule compartment, it engages with the guide groove. A coding scanner then reads the invisible tag on the capsule, and an infrared detection module checks the installation status. Once confirmed, the geared motor is activated, driving a lead screw that moves the door away from the capsule compartment, opening the bottom and allowing the tea bag / capsule to fall from the guide groove onto the clamping block below. The geared motor is then activated again, reversing the lead screw and retracting the door. This, in turn, moves the brewing chamber forward, pushing the tea bag / capsule towards the water outlet needle. The device moves until the inlet and outlet needles pierce the tea bag capsule cup from both sides. The inlet needles draw water to brew the original liquid in the tea bag capsule cup, and the tea flows out through the outlet needles, completing the automatic brewing process. After brewing, the reduction motor is restarted, causing the door to retract, which detaches the inlet and outlet needles from the tea bag capsule cup. This leaves the tea bag capsule cup unsupported, and it will automatically fall out from the bottom of the fixed support, completing the automatic detachment. The entire device integrates recognition and capsule dropping, enabling recognition, fully automatic capsule dropping, brewing, and capsule disposal functions after capsule placement, improving user experience and making operation convenient.

[0016] In this brewing mechanism, when the inlet needle is pulled back in the brewing chamber, the back of the tea bag capsule cup loses pressure. At this time, the push spring pushes the push rod through its elasticity, thereby pushing the tea bag capsule cup out from the outlet needle end. This ensures that the tea bag capsule cup can be smoothly separated from the outlet needle, thus avoiding the problem of the tea bag capsule cup being unable to detach and ensuring the stable implementation of the capsule dropping function.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Example 1

[0030] This embodiment provides an automatic cup-dispensing and brewing mechanism, such as Figure 1-9 As shown, the brewing mechanism includes a housing 1 and a cup-dropping brewing mechanism 3 fixedly installed inside the housing 1 for brewing the original liquid in the tea bag capsule cup 2.

[0031] The cup-dropping brewing mechanism 3 includes a fixed bracket 31 fixedly installed inside the housing 1 and a motor bracket 32 ​​fixedly installed at one end of the fixed bracket 31. A capsule chamber 34 is fixedly installed on the fixed bracket 31, and a geared motor 311 is fixedly installed on the motor bracket 32. A lead screw 312, passing through the motor bracket 32, is fixedly installed on the output end of the geared motor 311. A door 314, adapted to and located below the capsule chamber 34, is screwed onto the lead screw 312. A brewing chamber 315, adapted to the capsule chamber 34, is fixedly installed on the door 314. The brewing chamber 315... A water inlet needle 317 with its end facing into the brewing chamber 315 is fixedly installed. A water outlet needle 318, which is opposite to the water inlet needle 317, is fixedly installed on the fixed bracket 31 at the end opposite to the motor bracket 32. A guide groove 35, which is adapted to the tea bag capsule cup 2, is fixedly installed at the top position on the capsule chamber 34. A clamping block 38, which is adapted to the guide groove 35, is movably installed on the fixed bracket 31 at the position below the guide groove 35. An infrared detection module 37 is fixedly installed on the fixed bracket 31 on one side of the guide groove 35. An encoding recognition head 36 is fixedly installed on one side of the infrared detection module 37.

[0032] In use, the door 314 is initially closed. The tea bag / capsule cup 2 is placed into the capsule compartment 34, causing it to snap into the guide groove 35. The coding and identification head 36 then scans and identifies the invisible tag code on the tea bag / capsule cup 2. The infrared detection module 37 detects the installation status of the tea bag / capsule cup 2. Once confirmed, the reduction motor 311 is activated, driving the lead screw 312 to rotate. The lead screw 312 moves the door 314 away from the capsule compartment 34, opening the bottom of the capsule compartment 34. This allows the tea bag / capsule cup 2 to fall from the guide groove 35 onto the clamping block 38 below. The reduction motor 311 is then activated again, reversing the lead screw 312 and causing the door 314 to retract. This, in turn, moves the brewing chamber 315 forward, pushing the tea bag / capsule cup... The tea bag cup 2 moves towards the end of the water outlet needle 318 until the water inlet needle 317 and the water outlet needle 318 pierce into the tea bag capsule cup 2 from both sides. Water is introduced through the water inlet needle 317 to brew the original liquid in the tea bag capsule cup 2, and then the tea flows out through the water outlet needle 318, completing the automatic brewing. After brewing, the reduction motor 311 is started again, which drives the door 314 to move backward, so that the water inlet needle 317 and the water outlet needle 318 detach from the tea bag capsule cup 2. Thus, the tea bag capsule cup 2 is unsupported and will automatically fall out from the bottom of the fixed bracket 31, completing the automatic detachment. The entire device integrates recognition and capsule dropping. After placing the capsule, it can realize recognition + fully automatic capsule dropping + brewing + capsule discarding functions, improving the user experience and making operation convenient.

[0033] Specifically, a capsule mounting base 33 adapted to the capsule compartment 34 is fixedly installed on the housing 1, and the capsule mounting base 33 protrudes from the plane of the housing 1. In use, the internal space of the capsule mounting base 33 occupies half of the entire tea bag capsule cup 2, thereby ensuring stable support for the tea bag capsule cup 2 when it is installed and preventing it from rolling off.

[0034] More specifically, a water inlet connector 316, which is connected to the water inlet needle 317, is fixedly installed on the brewing chamber 315. In use, cold or hot water is introduced through the water inlet connector 316 connected to the external hose, and then pressurized through the water inlet needle 317 and poured into the tea bag capsule cup 2 to quickly brew the original liquid in the tea bag capsule cup 2. The operation is simple.

[0035] Furthermore, the fixed bracket 31 is provided with a reset spring cavity 39 that is adapted to the clamping block 38, and a reset spring 310 that abuts against the clamping block 38 is fixedly installed in the reset spring cavity 39. In use, the clamping block 38 is elastic when supporting the tea bag capsule cup 2, which makes it easy to fix or detach the tea bag capsule cup 2 and avoid jamming.

[0036] Furthermore, the clamping block 38 has a clamping cavity 323 with an arc-shaped cross-section that is compatible with the tea bag capsule cup 2. The groove depth on the side of the clamping cavity 323 facing the water outlet needle 318 is lower than the groove depth on the side away from the water outlet needle 318. The side of the clamping cavity 323 facing the water outlet needle 318 is a gently sloping cross-section. In use, when the brewing chamber 315 pushes the tea bag capsule cup 2 toward the water outlet needle 318, the mouth of the tea bag capsule cup 2 will disengage from the gentle slope on the clamping chamber 323, thus disengaging from the clamping block 38. This allows the tea bag capsule cup 2 to move smoothly to the water outlet needle 318 and pierce it. After the tea bag capsule cup 2 disengages from the clamping block 38, the clamping block 38 automatically springs back to its original position under the elastic force of the return spring 310. When the brewing chamber 315 subsequently disengages the tea bag capsule cup 2 after brewing, the clamping block 38 will press against the mouth ring of the tea bag capsule cup 2 from the back, preventing the water inlet tea bag capsule cup 2 from being pushed back along with the water inlet needle 317. This completes the disengagement of the water inlet needle 317 from the tea bag capsule cup 2, ensuring a very stable disengagement.

[0037] A flange 313 is fixedly installed at the connection point between the lead screw 312, the end furthest from the geared motor 311, and the door 314. In use, the lead screw 312 and the door 314 are connected via the flange 313 for easy disassembly and maintenance.

[0038] Example 2

[0039] Unlike Embodiment 1, when detaching the tea bag capsule cup 2 from the water outlet needle 318, the tea bag capsule cup 2 may be difficult to detach due to the piercing and fixing effect of the water outlet needle 318. Therefore, a push rod 319 extending towards the water inlet needle 317 is inserted into the side of the fixing bracket 31 that is coplanar with the water outlet needle 318. A push spring 320 is fixedly installed between the fixing bracket 31 and the tail end of the push rod 319. During use, when the water inlet needle 317 is pulled back in the brewing chamber 315, the back of the tea bag capsule cup 2 loses pressure. At this time, the push spring 320 pushes the push rod 319 through its elastic force, thereby pushing the tea bag capsule cup 2 out from one end of the water outlet needle 318, ensuring that the tea bag capsule cup 2 can smoothly detach from the water outlet needle 318, thus avoiding the problem of the tea bag capsule cup 2 being unable to detach and ensuring the stable implementation of the capsule dispensing function.

[0040] Furthermore, the fixed bracket 31 is symmetrically provided with movable slots 322 that are adapted to the chamber door 314 and the brewing chamber 315. A position sensor 321 is fixedly installed on one side of the movable slot 322 on the fixed bracket 31. In use, the position sensor 321 senses the movement position of the chamber door 314 to ensure stable operation of the equipment.

[0041] Furthermore, a sealing ring 324, compatible with the tea bag capsule cup 2, is fixedly installed on the side of the fixed bracket 31 that is coplanar with the water outlet needle 318 and faces the brewing chamber 315. During use, when the tea bag capsule cup 2 is pushed to the side of the water outlet needle 318, the sealing ring 324 compresses and seals one side of the tea bag capsule cup 2, thereby ensuring that no leakage occurs when brewing the original liquid inside the tea bag capsule cup 2, ensuring smooth brewing.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
