Description

Technical Field

[0001] This utility model relates to the field of tea brewing machine technology, specifically to a multi-head expandable tea brewing system. Background Technology

[0002] Existing tea brewing machines are typically independent, vertical units with a built-in main unit, paired with a brewing tank and a dispensing tank to control the temperature and quantity of tea. However, in commercial settings such as milk tea shops, businesses often need to precisely control the temperature and volume of various types of tea. Purchasing multiple separate units would be too costly. While there are currently tea brewing systems with one main unit and multiple sub-units, such as the one disclosed in Chinese Patent Publication No. CN221012912U, this system has several shortcomings. On the one hand, it is difficult to individually control the temperature of each sub-unit, and it is also difficult to achieve timed and quantitative operation. On the other hand, due to the varying distances between the sub-units and the main unit, in low temperatures during winter, the exposed pipes result in significant heat loss, making it difficult to achieve the required brewing temperature. These problems make the system unsuitable for the parallel operation of multiple tea brewing devices in commercial settings, thus affecting the quality and taste of the tea. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-head expandable tea brewing system.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A multi-head expandable tea brewing system includes a main unit and at least two sub-units. The main unit has built-in heating pipes and room temperature water pipes, and the sub-units have built-in tea dispensing mechanisms and detection mechanisms.

[0006] The heating system includes a hot water tank and a water pump. One end of the hot water tank is connected to the water inlet pipe, and the other end of the hot water tank is connected to the hot water solenoid valve through the water pump.

[0007] The ambient temperature water pipeline includes an ambient temperature water solenoid valve and an ambient temperature water sensor. One end of the ambient temperature water solenoid valve is connected to the water inlet pipe, and the other end of the ambient temperature water solenoid valve is connected to the hot water solenoid valve and then connected to the tee pipe.

[0008] The tea dispensing mechanism includes a solenoid valve, a motor push rod, and a tea brewing barrel. One end of the solenoid valve is connected to a three-way pipe, and the solenoid valve is connected to the water outlet at the top of the tea brewing barrel. The motor push rod drives the water outlet at the bottom of the tea brewing barrel. Space is reserved below the tea brewing barrel for the tea barrel itself.

[0009] The testing mechanism includes infrared sensor I and infrared sensor II. Infrared sensor I is located on the back of the tea brewing barrel on the sub-unit, and infrared sensor II is located on the back of the tea dispensing barrel on the sub-unit.

[0010] This technical solution utilizes a multi-head expansion method, allowing one main unit to brew tea for different sub-units. Heating and ambient temperature water pipes enable quantitative and temperature control of the sub-units; a motor push rod, in conjunction with the sub-unit's solenoid valve, allows for timed dispensing of tea. This solution is suitable for commercial milk tea shops and other scenarios requiring multiple tea brewing devices to operate in parallel. For example, if one sub-unit brews 3L of 95℃ black tea and another brews 1L of 80℃ green tea, 100℃ hot water heated by the main unit can be mixed with ambient temperature water and pumped separately to the corresponding sub-units.

[0011] In addition, the multi-head extended tea brewing system proposed above according to this utility model may also have the following additional technical features:

[0012] According to one embodiment of the present invention, the sub-unit is further provided with a return water pipeline, which includes a three-way solenoid valve. The inlet end of the three-way solenoid valve is connected to the solenoid valve of the sub-unit, the outlet end of the three-way solenoid valve is connected to the outlet above the tea brewing barrel, and the return end of the three-way solenoid valve is connected to the hot water tank of the main unit through the return water outlet.

[0013] In this technical solution, since the distance between the main unit and different sub-units varies, the greater the distance, the longer the exposed pipe length, especially in winter, which causes heat loss. Therefore, the return water pipe needs to periodically heat the water inlet section of the sub-unit. For example, if the sub-unit is not in use every half hour, the three-way solenoid valve of that sub-unit is opened to preheat part of the return water pipe with hot water.

[0014] According to one embodiment of the present invention, the three-way solenoid valve is a two-position solenoid valve, with its normally open end located at the return water port and its normally closed end located at the outlet water port.

[0015] In this technical solution, the three-way solenoid valve is located in the tea dispensing mechanism. It extends a pipeline along the pipeline where the sub-unit solenoid valve is located towards the hot water tank, thereby periodically returning water to the pipeline and preventing cooled water from remaining in the sub-unit.

[0016] According to one embodiment of the present invention, the lower part of the hot water tank is connected to tap water through an inlet solenoid valve. The hot water tank has a built-in heating tube, and the hot water heated by the heating tube is pumped into a three-way pipe through a water pump. The bottom of the hot water tank is also provided with a drain pipe, and a drain valve is provided on the drain pipe.

[0017] In this technical solution, a drain overflow valve is also installed on the top of the hot water tank, and a temperature sensor for detecting temperature is also installed in the hot water tank.

[0018] According to one embodiment of the present invention, a flow meter is also installed on the ambient temperature water pipeline.

[0019] In this technical solution, the flow meter detects the flow rate of room temperature water, thereby controlling the opening and closing degree of the room temperature water solenoid valve, and working with hot water to achieve temperature control of room temperature water.

[0020] According to one embodiment of the present invention, the motor push rod includes a push rod, a hinge shaft, a lever, and a spring piece, wherein: the push rod is located inside the sub-unit, the bottom of the push rod is connected to the lever through the hinge shaft, the middle part of the lever is movably mounted on the sub-unit, and the end of the lever abuts against the outlet of the tea brewing barrel through the spring piece; the tea slurry in the tea brewing barrel falls into the tea dispensing barrel below through the water outlet.

[0021] In this technical solution, the motor push rod is used to realize the timed discharge of tea slurry from the tea brewing barrel, saving manual waiting time.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] (1) Through the multi-head expansion structure of one to many, one host can control multiple sub-units to brew tea in parallel. The heating pipeline and the normal temperature water pipeline are used to realize the quantitative and constant temperature control of the sub-units, meet the brewing needs of different tea drinks, and are suitable for commercial scenarios such as milk tea shops, thus improving work efficiency.

[0024] (2) The sub-unit is equipped with a return water pipeline. The pipeline is preheated at regular intervals by a three-way solenoid valve to avoid heat loss. This can effectively reduce energy waste, especially in winter, and at the same time ensure that the water temperature of the sub-unit is suitable, thus improving the quality of tea brewing.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, this embodiment provides a multi-head expandable tea brewing system, including a main unit 1 and at least two sub-units 2. The main unit 1 has built-in heating pipes and room temperature water pipes, and the sub-units 2 have built-in tea dispensing mechanisms and detection mechanisms, wherein:

[0032] The heating pipeline includes a hot water tank 11 and a water pump 12. One end of the hot water tank 11 is connected to the water inlet pipe, and the other end of the hot water tank 11 is connected to the hot water solenoid valve 13 through the water pump 12.

[0033] The ambient temperature water pipeline includes an ambient temperature water solenoid valve 14 and an ambient temperature water sensor 15. One end of the ambient temperature water solenoid valve 14 is connected to the water inlet pipe, and the other end of the ambient temperature water solenoid valve 14 is connected to the hot water solenoid valve 13 and then connected to the three-way pipeline.

[0034] The tea dispensing mechanism includes a solenoid valve 21, a motor push rod, and a tea brewing tank 22. One end of the solenoid valve 21 is connected to a three-way pipe, and the solenoid valve 21 is connected to the water outlet 212 at the top of the tea brewing tank 22. The motor push rod drives the water outlet 212 at the bottom of the tea brewing tank 22. A space is reserved below the tea brewing tank 22 for the location of the tea tank 29.

[0035] The detection mechanism includes infrared sensor I 23 and infrared sensor II 24. Infrared sensor I 23 is located on the back of the tea brewing barrel 22 on the sub-unit 2, and infrared sensor II 24 is located on the back of the tea dispensing barrel 29 on the sub-unit 2.

[0036] like Figures 1 to 3 As shown, this technical solution utilizes a multi-head expansion method, enabling one main unit 1 to brew tea for different sub-units 2. It achieves quantitative and temperature control of sub-units 2 using heating and ambient temperature water pipes; and uses a motor push rod in conjunction with the sub-unit's solenoid valve 21 to time the dispensing of tea. This technical solution is applicable to commercial milk tea shops and other scenarios requiring multiple tea brewing devices to operate in parallel. For example, if one sub-unit 2 brews 3L of 95℃ black tea and another sub-unit 2 brews 1L of 80℃ green tea, then 100℃ hot water heated by the main unit 1 can be mixed with ambient temperature water and pumped separately into the corresponding sub-units 2.

[0037] In addition, the multi-head extended tea brewing system proposed above according to this utility model may also have the following additional technical features:

[0038] According to one embodiment of the present invention, the sub-unit 2 is further provided with a return water pipeline, which includes a three-way solenoid valve 210. The inlet end of the three-way solenoid valve 210 is connected to the sub-unit solenoid valve 21, the outlet end of the three-way solenoid valve 210 is connected to the outlet 212 above the tea brewing barrel 22, and the return end of the three-way solenoid valve 210 is connected to the hot water tank 11 of the main unit 1 through the return water port 211.

[0039] In this technical solution, since the distances between the main unit 1 and the different branch units 2 vary, the greater the distance, the longer the exposed pipe length, especially in winter, which will cause heat loss. Therefore, the return water pipe needs to be used to heat the water inlet of the branch unit 2 at regular intervals. For example, if the branch unit 2 is not in use every half hour, the three-way solenoid valve 210 of the branch unit 2 is opened to preheat part of the return water pipe with hot water.

[0040] According to one embodiment of the present invention, the three-way solenoid valve 210 is a two-position solenoid valve, with its normally open end located at the return port 211 and its normally closed end located at the outlet 212.

[0041] In this technical solution, the three-way solenoid valve 210 is located in the tea dispensing mechanism. It extends a pipeline along the pipeline where the sub-unit solenoid valve 21 is located toward the hot water tank 11, thereby periodically returning water to the pipeline and preventing cooled water from remaining in the sub-unit 2.

[0042] According to one embodiment of the present invention, the lower part of the hot water tank 11 is connected to tap water through the water inlet solenoid valve 17. The hot water tank 11 has a built-in heating tube. The hot water heated by the heating tube is pumped into the three-way pipe through the water pump 12. The bottom of the hot water tank 11 is also provided with a drain pipe, and a drain valve 18 is provided on the drain pipe.

[0043] In this technical solution, a drain overflow valve is also provided on the top of the hot water tank 11, and a temperature sensor for detecting temperature is also provided in the hot water tank 11.

[0044] According to one embodiment of the present invention, a flow meter 16 is also provided on the ambient temperature water pipeline.

[0045] In this technical solution, the flow meter 16 detects the flow rate of room temperature water, thereby controlling the opening and closing degree of the room temperature water solenoid valve, and cooperating with hot water to achieve temperature control of room temperature water.

[0046] According to one embodiment of the present invention, the motor push rod includes a push rod 25, a hinge shaft 26, a lever 27, and a spring piece 28, wherein: the push rod 25 is located inside the sub-unit 2, the bottom of the push rod 25 is connected to the lever 27 through the hinge shaft 26, the middle part of the lever 27 is movably mounted on the sub-unit 2, and the end of the lever 27 abuts against the outlet of the tea brewing barrel 22 through the spring piece 28; the tea in the tea brewing barrel 22 falls into the tea dispensing barrel 29 below through the water outlet 212.

[0047] In this technical solution, the motor push rod is used to realize the timed discharge of tea slurry from the tea brewing tank 22, saving manual waiting time.

[0048] The usage process of the above embodiments is as follows: Figures 1 to 3 As shown, the main unit 1 is connected to tap water through the inlet pipe. The heating element in the hot water tank 11 heats the water, and the water pump 12 pumps the hot water to the hot water solenoid valve 13. Room temperature water flows into the three-way pipe through the inlet pipe and the room temperature water solenoid valve 14. The flow meter 16 detects the flow rate of the room temperature water and controls the opening and closing degree of the room temperature water solenoid valve 14 to achieve a constant temperature with the hot water. According to the needs, the hot water and room temperature water are mixed in the three-way pipe and then flow into the tea brewing tank 22 through the distributor solenoid valve 21. In the tea dispensing mechanism, the motor push rod passes through the push rod 25, the hinge shaft 26, the lever 27 and the spring 2. The system coordinates with the following: The bottom outlet 212 of the tea brewing tank 22 is pushed periodically, causing the tea to fall into the tea dispensing tank 29 below; Infrared sensor I 23 of the detection mechanism monitors the status of the tea brewing tank 22, and infrared sensor II 24 monitors the status of the tea dispensing tank 29; The three-way solenoid valve 210 of the return water pipe opens periodically. If the interval between brewing sessions exceeds the set time, the return water pipe must be preheated before brewing again to prevent heat loss; The hot water tank 11 is also equipped with a drain pipe, a drain overflow valve, and a temperature sensor to ensure stable system operation. This invention is suitable for scenarios where multiple units 2 operate in parallel, achieving quantitative and temperature-controlled tea brewing while saving labor.
