In this way, when brewing, the initial state of the compartment door is closed, and the tea bag capsule cup is placed in the capsule compartment so that the tea bag capsule cup is stuck in the guide groove. Then the coding recognition head scans and recognizes the invisible label code on the tea bag capsule cup, and the infrared detection module detects the installation status of the tea bag capsule cup. After confirmation, the reduction motor is started, and the reduction motor drives the screw rod to rotate, and the screw rod drives the compartment door away from the capsule compartment, so that the bottom of the capsule compartment opens, so that the tea bag capsule cup falls from the guide groove to the clamping block below, and then the reduction motor is started again, the screw rod is reversed, and the compartment door is driven back, thereby driving the brewing cavity to move forward together and push the tea bag capsule cup towards the water outlet. One end of the needle moves until the water inlet needle and the water outlet needle pierce the tea bag capsule cup from both sides, and water is drawn in through the water inlet needle to brew the original liquid in the tea bag capsule cup, and then the tea flows out through the water outlet needle to complete the automatic brewing. After the brewing is completed, the reduction motor is started again to drive the warehouse door to retreat, so that the water inlet needle and the water outlet needle are separated from the tea bag capsule cup, so that the tea bag capsule cup is unsupported, and the tea bag capsule cup will automatically fall out from the bottom of the fixed bracket to complete the automatic separation. The entire equipment recognizes and drops the capsule in one, and after placing the capsule, it can realize the functions of recognition + fully automatic capsule dropping + brewing + capsule discarding, thereby improving the user experience and facilitating operation.

[0007] Preferably, in order to install the tea bag capsule cup, a capsule mounting seat adapted to the capsule bin is fixedly mounted on the shell, and the capsule mounting seat is arranged to protrude from the plane of the shell, thereby ensuring that the tea bag capsule cup is stably supported when the tea bag capsule cup is installed to prevent it from rolling down.

[0008] Preferably, in order to receive water for brewing, a water inlet joint connected to the water inlet needle is fixedly installed on the brewing cavity, so that the original liquid in the tea bag capsule cup can be brewed quickly, and the operation is simple.

[0009] Preferably, in order to withdraw the tea bag capsule cup, the fixed bracket is provided with a reset spring chamber adapted to the clamping block, and a reset spring against the clamping block is fixedly installed in the reset spring chamber, so that the water inlet needle puncture and the tea bag capsule cup are separated, which is very stable.

[0010] Preferably, in order to ensure that the tea bag capsule cup is separated from the water outlet needle, the clamping block is provided with a clamping cavity with an arc surface in cross section adapted to 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 is provided with a gentle slope section, which is convenient for fixing or separating the tea bag capsule cup and avoiding jamming.

[0011] Preferably, for the convenience of maintenance, a flange is fixedly mounted at the connection between the end of the screw rod away from the reduction motor and the warehouse door. The screw rod and the warehouse door are connected through the flange, which is convenient for disassembly and maintenance.

[0012] Preferably, in order to push out the tea bag capsule cup, a push rod extending toward the water inlet needle is inserted on the side of the fixed bracket coplanar with the water outlet needle, and a push spring is fixedly installed between the fixed bracket and the tail end of the push rod to ensure that the tea bag capsule cup can be smoothly separated from the water outlet needle.

[0013] Preferably, in order to ensure stable brewing, the fixed bracket is symmetrically provided with movable grooves adapted to the compartment door and the brewing cavity, and a position sensor is fixedly installed on one side of the movable groove on the fixed bracket to ensure stable operation of the device.

[0014] Preferably, in order to ensure the brewing environment, a sealing rubber ring adapted to the tea bag capsule cup is fixedly installed on the fixed bracket on the side coplanar with the water outlet needle and facing the brewing cavity, thereby ensuring that there will be no leakage when the original liquid in the tea bag capsule cup is brewed, ensuring smooth brewing.

[0015] The brewing mechanism has a door that is initially in a closed state. The tea bag capsule cup is placed in the capsule compartment so that the tea bag capsule cup is stuck in the guide groove. The coding recognition head then scans and recognizes the invisible label code on the tea bag capsule cup. The infrared detection module detects the installation status of the tea bag capsule cup. After confirmation, the reduction motor is started, and the reduction motor drives the screw rod to rotate. The screw rod drives the compartment door away from the capsule compartment, so that the bottom of the capsule compartment opens, thereby allowing the tea bag capsule cup to fall from the guide groove onto the clamping block below. The reduction motor is then started again, the screw rod is reversed, and the compartment door is driven back, thereby driving the brewing cavity to move forward together and push the tea bag capsule cup toward the water outlet needle. The piercing end moves until the water inlet needle and the water outlet needle pierce into the tea bag capsule cup from both sides, and water is drawn in through the water inlet needle to brew the original liquid in the tea bag capsule cup, and then the tea flows out through the water outlet needle to complete the automatic brewing. After the brewing is completed, the reduction motor is started again to drive the warehouse door to retreat, so that the water inlet needle and the water outlet needle are separated from the tea bag capsule cup, so that the tea bag capsule cup is unsupported, and the tea bag capsule cup will automatically fall out from the bottom of the fixed bracket to complete the automatic separation. The entire equipment recognizes and drops the capsule in one, and after placing the capsule, it can realize the functions of recognition + fully automatic capsule dropping + brewing + capsule discarding, which improves the user experience and is convenient to operate.

[0016] In this brewing mechanism, when the brewing cavity is pulled back for water inlet needle, the back of the tea bag capsule cup loses pressure. At this time, the push spring pushes the push rod through elastic force, thereby pushing the tea bag capsule cup out from one end of the water outlet needle, ensuring that the tea bag capsule cup can be smoothly separated from the water outlet needle, thereby avoiding the problem that the tea bag capsule cup cannot be separated and ensuring the stable implementation of the capsule dropping function.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Example 1

[0030] This embodiment provides an automatic cup dropping 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 in 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 in the shell 1 and a motor bracket 32 ​​fixedly installed at one end of the fixed bracket 31, a capsule bin 34 is fixedly installed on the fixed bracket 31, a reduction motor 311 is fixedly installed on the motor bracket 32, a screw rod 312 penetrating the motor bracket 32 ​​is fixedly installed on the output end of the reduction motor 311, a bin door 314 adapted to the capsule bin 34 and located below the capsule bin 34 is screwed on the screw rod 312, a brewing cavity 315 adapted to the capsule bin 34 is fixedly installed on the bin door 314, and a brewing cavity 315 is fixedly installed on the brewing cavity 315. A water inlet needle 317 is fixedly installed with its end facing the brewing cavity 315, a water outlet needle 318 arranged opposite to the water inlet needle 317 is fixedly installed on the end of the fixed bracket 31 opposite to the motor bracket 32, a guide groove 35 adapted to the tea bag capsule cup 2 is fixedly installed at the top position on the capsule compartment 34, a clamping block 38 adapted to the guide groove 35 is movably installed at a position below the guide groove 35 on the fixed bracket 31, an infrared detection module 37 is fixedly installed on one side of the guide groove 35 on the fixed bracket 31, and a coding recognition head 36 is fixedly installed on one side of the infrared detection module 37.

[0032] When in use, the initial state of the compartment door 314 is closed, and the tea bag capsule cup 2 is placed in the capsule compartment 34 so that the tea bag capsule cup 2 is stuck in the guide groove 35. Then the coding recognition head 36 scans and recognizes the invisible label code on the tea bag capsule cup 2, and the infrared detection module 37 detects the installation state of the tea bag capsule cup 2. After confirmation, the reduction motor 311 is started, and the reduction motor 311 drives the screw rod 312 to rotate, and the screw rod 312 drives the compartment door 314 away from the capsule compartment 34, so that the bottom of the capsule compartment 34 opens, so that the tea bag capsule cup 2 falls from the guide groove 35 to the clamping block 38 below, and then the reduction motor 311 is started again, the screw rod 312 is reversed, and the compartment door 314 is driven to retreat, thereby driving the brewing cavity 315 to move forward together to push the tea bag capsule 2. The capsule cup 2 moves toward one end of the water outlet needle 318 until the water inlet needle 317 and the water outlet needle 318 pierce the tea bag capsule cup 2 from both sides, and the original liquid in the tea bag capsule cup 2 is brewed by the water inlet needle 317, and then the tea flows out through the water outlet needle 318 to complete the automatic brewing. After the brewing is completed, the reduction motor 311 is started again to drive the compartment door 314 to retreat, so that the water inlet needle 317 and the water outlet needle 318 are separated from the tea bag capsule cup 2, so that the tea bag capsule cup 2 is unsupported, and the tea bag capsule cup 2 will automatically fall out from the bottom of the fixed bracket 31 to complete the automatic separation. The entire device recognizes and drops the capsule in one, and after placing the capsule, the functions of recognition + fully automatic capsule dropping + brewing + capsule discarding can be realized, thereby improving the user experience and facilitating the operation.

[0033] Specifically, a capsule mounting seat 33 adapted to the capsule compartment 34 is fixedly mounted on the shell 1, and the capsule mounting seat 33 is arranged to protrude from the plane of the shell 1. When in use, the internal space of the capsule mounting seat 33 occupies one half of the entire tea bag capsule cup 2, thereby ensuring that the tea bag capsule cup 2 is stably supported when the tea bag capsule cup 2 is installed to prevent it from rolling down.

[0034] More specifically, a water inlet connector 316 connected to the water inlet needle 317 is fixedly mounted on the brewing cavity 315. When in use, the water inlet connector 316 is connected via an external hose, cold water or hot water is introduced, and then pressurized into the tea bag capsule cup 2 through the water inlet needle 317, so that the original liquid in the tea bag capsule cup 2 is quickly brewed, and the operation is simple.

[0035] Furthermore, the fixing bracket 31 is provided with a reset spring cavity 39 adapted to the clamping block 38, and a reset spring 310 is fixedly installed in the reset spring cavity 39 to abut against the clamping block 38. When in use, the clamping block 38 is elastic when supporting the tea bag capsule cup 2, which is convenient for fixing or detaching the tea bag capsule cup 2 to avoid getting stuck.

[0036] Furthermore, the clamping block 38 is provided with a clamping cavity 323 having an arc-shaped cross section and adapted to 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 sloped section. During use, when the brewing cavity 315 drives the tea bag capsule cup 2 to push toward the water outlet needle 318, the cup mouth of the tea bag capsule cup 2 will separate from the gentle slope of the clamping cavity 323, thereby separating from the clamping block 38, so that the tea bag capsule cup 2 can smoothly move to the water outlet needle 318 and contact and penetrate the water outlet needle 318. When the tea bag capsule cup 2 separates from the clamping block 38, the clamping block 38 automatically rebounds and resets due to the elastic force of the reset spring 310. When the brewing cavity 315 drives the tea bag capsule cup 2 to separate after the brewing is completed, the clamping block 38 will reset and press against the cup mouth ring of the tea bag capsule cup 2 from the back, so that the water-intake tea bag capsule cup 2 will not continue to be pushed back with the water inlet needle 317, and the water inlet needle 317 and the tea bag capsule cup 2 are separated, which is very stable.

[0037] Among them, a flange 313 is fixedly installed at the connection between the end of the screw rod 312 away from the reduction motor 311 and the warehouse door 314. When in use, the screw rod 312 and the warehouse door 314 are connected through the flange 313, which is convenient for disassembly and maintenance.

[0038] Example 2

[0039] Different from the first embodiment, when the tea bag capsule cup 2 is separated from the water outlet needle 318, the tea bag capsule cup 2 may be difficult to separate due to the puncture fixation of the water outlet needle 318. For this reason, a push rod 319 extending toward the water inlet needle 317 is inserted on the side of the fixed bracket 31 coplanar with the water outlet needle 318, and a push spring 320 is fixedly installed between the fixed bracket 31 and the tail end of the push rod 319. When in use, when the brewing cavity 315 pulls back the water inlet needle 317, the back of the tea bag capsule cup 2 loses pressure. At this time, the push spring 320 pushes the push rod 319 through 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 be separated from the water outlet needle 318 smoothly, thereby avoiding the problem that the tea bag capsule cup 2 cannot be separated, and ensuring the stable implementation of the capsule dropping function.

[0040] Furthermore, the fixed bracket 31 is symmetrically provided with a moving groove 322 adapted to the door 314 and the brewing cavity 315, and a position sensor 321 is fixedly installed on one side of the moving groove 322 on the fixed bracket 31. When in use, the position sensor 321 senses the moving position of the door 314 to determine the stable operation of the device.

[0041] Furthermore, a sealing rubber ring 324 adapted to the tea bag capsule cup 2 is fixedly installed on the fixed bracket 31 on the side coplanar with the water outlet needle 318 and facing the brewing cavity 315. When in use, when the tea bag capsule cup 2 is pushed to the side of the water outlet needle 318, the sealing rubber ring 324 squeezes and seals one side of the tea bag capsule cup 2, thereby ensuring that there is no leakage when the original liquid in the tea bag capsule cup 2 is brewed, ensuring smooth brewing.

[0042] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
