[0045] Referring to Figure 1 、 Figure 2 , one embodiment of the present utility model provides a scanning code tea-making control system for a tea-making machine, including:

[0046] A label recognition module 200, a control module 300, a water supply module 400, a heating module 500, and a soup outlet module 600;

[0047] The label recognition module 200, the water supply module 400, the heating module 500, and the soup outlet module 600 are all electrically connected to the control module 300;

[0048] The water supply module 400 is connected to the heating module 500 through a pipeline;

[0049] The label recognition module 200 is used to photograph and recognize a tea leaf label to decode and generate a digital signal corresponding to the label, and send it to the control module 300;

[0050] Specifically: The tea leaf label includes a two-dimensional code or a bar code. The label recognition module 200 includes a camera assembly, a decoder, and a memory; the camera assembly is used to photograph the two-dimensional code or the bar code, the memory is used to pre-store tea leaf information associated with the tea leaf label, the tea leaf information is the tea variety, the water temperature and the tea-making time when making tea with this tea variety, and the decoder is used to read the two-dimensional code or the bar code and generate a digital signal to send to the control module 300.

[0051] The control module 300 is used to receive the corresponding digital signal and convert it into an analog signal; the control module 300 is used to send a corresponding temperature control signal to the heating module 500 according to the analog signal to control the heating module 500 to heat to a preset temperature; the control module 300 is used to control the connection and disconnection between the heating module 500 and the soup outlet module 600, and to control the opening and closing of the soup outlet module 600.

[0052] Specifically, the control module 300 includes a temperature sensor 310, a digital-to-analog converter 320, a microcontroller 330, a switch unit 340, and a 555 timing unit 350. The 555 timing unit 350 is set with a first preset duration and a second preset duration;

[0053] The temperature sensor 310 is used to monitor the water temperature in the heating module 500 in real time. The temperature sensor 310 is preset with a plurality of temperature thresholds. The control module 300 is used to switch the temperature thresholds of the temperature sensor 310 according to the analog signal. When the water temperature in the heating module 500 is greater than the temperature threshold, the control module 300 issues a switch signal to turn off the heating module 500.

[0054] The digital-to-analog converter 320 is used to convert the received digital signal into an analog signal and send it to the microcontroller 330;

[0055] The microcontroller 330 is set with a temperature threshold for comparing the temperature signal fed back by the temperature sensor 310. The microcontroller 330 is used to set the temperature threshold of the temperature sensor 310 according to the analog signal, and issue a temperature control signal to the switch unit 340 according to the comparison result of the temperature signal and the temperature threshold. That is, a reference voltage for comparing the temperature threshold is set in the microcontroller 330. After converting the received digital signal into an analog signal, the analog signal refers to this reference voltage. Each time an analog signal is received, the reference voltage of the received analog signal is set as the temperature threshold. The temperature sensor 310 also feeds back the detected temperature to the microcontroller 330 as a voltage value. When the temperature sensor 310 feeds back the detected temperature to the microcontroller 330, it is compared with the reference voltage in the microcontroller 330. When the temperature exceeds the temperature threshold, a temperature control signal is issued to the switch unit 340 to stop heating.

[0056] The temperature control signal includes a heating start signal and a heating stop signal;

[0057] When the microcontroller 330 receives the corresponding analog signal, it issues a heating start signal to the heating module 500. The temperature sensor 310 monitors the water temperature in the heating module 500 in real time and sends a temperature signal to the microcontroller 330. When the temperature signal is greater than or equal to the temperature threshold signal, the microcontroller 330 issues a heating stop signal to the heating module 500.

[0058] When the heating module 500 receives a heating-off signal, the microcontroller 330 sends an on-control signal to the switch unit 340. When the switch unit 340 receives the on-control signal, it connects the heating module 500 and the soup-dispensing module 600, and the microcontroller 330 sends a start signal to the 555 timing unit 350 to enable the 555 timing unit 350 to start a countdown for a first preset duration;

[0059] When the countdown for the first preset duration ends, the microcontroller 330 sends an off-control signal to the switch unit 340. When the switch unit 340 receives the off-control signal, it disconnects the heating module 500 and the soup-dispensing module 600 and starts a countdown for a second preset duration;

[0060] When the countdown for the second preset duration ends, the microcontroller 330 sends a soup-dispensing control signal to the switch unit 340. When the switch unit 340 receives the soup-dispensing control signal, it turns on the soup-dispensing module 600.

[0061] The first preset duration is the time for the hot water in the heating module 500 to flow to the soup-dispensing module 600, and the second preset duration is the tea-brewing time.

[0062] Among them, the second preset duration is associated with the tea label. Different tea labels decode to generate corresponding digital signals that are different. The analog signals converted from different digital signals correspond to different temperature thresholds, and the second preset durations corresponding to the analog signals converted from different digital signals are also different. That is, different teas require different water temperatures and tea-brewing times. In this way, multiple different digital signals can be formed, and the digital signals received by the control module 300 are different.

[0063] Among them, when the same tea variety label is used, the digital signal includes n digital sub-signals, and the temperature thresholds and the second preset durations corresponding to each digital sub-signal are different. That is, in the same tea, the water temperature and the tea-brewing time required for each brewing are also different. In this way, there can be n digital sub-signals in the same digital signal, and the corresponding water temperature and tea-brewing time in each digital sub-signal are also different. n is the number of times of brewing for a certain variety of tea. For example, when a certain variety of tea is brewed for the first time, the required temperature is 90 °C and the tea-brewing time is 3 s. Then the temperature threshold of the corresponding digital sub-signal is 90 °C, and the time of the second preset duration is 3 s.

[0064] The specific water temperature and tea-brewing time are set according to actual needs in actual use, and the corresponding signal transmission is clear to those skilled in the art and will not be elaborated here.

[0065] In one of the embodiments, refer to Figure 3, the label recognition module 200, the control module 300, the water supply module 400, the heating module 500, and the tea dispensing module 600 are all installed in the tea-making machine 100. Figure 2 It is a schematic diagram of the positions of each module, which is convenient for those skilled in the art to understand the technical solution of the present application. The water supply module 400 includes a water inlet pipe 410 and a valve body 420 provided on the water inlet pipe 410. The valve body 420 is electrically connected to the control module 300; one end of the water inlet pipe 410 is connected to the heating module 500, and the other end is externally connected to a water source. The heating module 500 includes a heating tank 510 and a first water outlet 520 provided at the bottom of the heating tank 510; the heating tank 510 is electrically connected to the control module 300; a first valve 530 is provided on the first water outlet 520, and the first valve 530 is electrically connected to the control module 300. When the heating module 500 receives a heating-off signal, the first valve 530 opens. The tea dispensing module 600 includes a tea cup 610 and a second water outlet 620 provided at the bottom of the tea cup 610; the first water outlet 520 at the bottom of the heating tank 510 faces the tea cup 610; a second valve 630 is provided on the second water outlet 620, and the second valve 630 is electrically connected to the control module 300. When the tea dispensing module 600 receives a tea-dispensing control signal, the second valve 630 opens. A fair cup 700 is provided below the tea cup 610, and the second water outlet 620 at the bottom of the tea cup 610 faces the fair cup 700.

[0066] The valve body 420 is used to add the external water source into the heating tank 510 of the heating module 500 through the water inlet pipe 410. The valve body 420 can be a one-way pressure reducing valve or a water pump. The heating tank 510 is a commonly used heating tank in the art and is used to heat the connected water source. Among them, when the water source is connected, the heating tank 510 preheats the water and keeps it at 70 °C. The water temperature is monitored in real time through the temperature sensor 310, so that when making tea for subsequent use, it can be quickly heated to the specified temperature; the temperature sensor 310 is used to monitor the water temperature of the heating tank 510 during tea making and feedback it to the control module 300 in real time. Tea leaves are placed in the tea cup 610 for soaking. The first valve 530 and the second valve 630 are normally closed valves, and solenoid valves or other valves with the same function can be used. The first valve 530 opens after the water in the heating tank 510 is heated to the specified temperature, and the hot water flows into the tea cup 610. The second valve 630 opens after the tea leaves in the tea cup 610 are soaked for the corresponding time, and the tea water flows into the fair cup 700.

[0067] When the ordinary heating tank 510 uses stainless steel as the heating medium to heat water as needed, it is easy to produce a metallic odor, which affects the quality and taste of the tea. By providing a protective layer (not shown in the figure) inside the heating tank 510, the protective layer is a ceramic protective layer or other suitable materials or coatings to achieve the same protective effect and solve the problem of metallic odor generated during the boiling process of water.

[0068] One principle of this application is:

[0069] Enter the water temperature and brewing time information required for each type of tea when brewing in a small program or web page. Among them, the water temperature and brewing time required for each type of tea when brewing are different for each brewing, so as to form different QR code or barcode pictures.

[0070] Among them, when brewing tea, the distinction between the first brewing and the second brewing, the third brewing... can be made through the "start button" on the tea brewing machine 100. When the tea brewing machine 100 is powered on, the camera component scans the QR code or barcode, and the decoder reads the QR code or barcode and generates a digital signal to send to the digital-to-analog converter 320 of the control module 300. After the digital-to-analog converter 320 converts the received digital signal into an analog signal and sends it to the microcontroller 330, pressing the start button for the first time is the first brewing. After the first brewing ends, pressing the start button for the second time is the second brewing. Or a touch switch, slow infrared reflection instruction, ultrasonic reflection instruction, etc. can be used.

[0071] Taking the example of brewing the "English Black Tea No. 9 Golden Tip" tea, a total of five brews are set (the water temperature for the first brew is 90 °C and the brewing time is 2 s; the water temperature for the second brew is 85 °C and the brewing time is 1 s; the water temperature for the third brew is 88 °C and the brewing time is 3 s; the water temperature for the fourth brew is 90 °C and the brewing time is 3 s; the water temperature for the fifth brew is 90 °C and the brewing time is 7 s):

[0072] When pressing the start button for the first brew, when the microcontroller 330 receives the corresponding analog signal, it sends a heating start signal to the heating tank 510 of the heating module 500. The heating tank 510 of the heating module 500 heats the water, and the temperature sensor 310 monitors the water temperature in the heating tank 510 in real time and sends a temperature signal to the microcontroller 330. When the temperature signal is greater than or equal to the temperature threshold signal, that is, when the water temperature reaches 90 °C, the microcontroller 330 sends a heating off signal to the heating tank 510 to stop heating the water.

[0073] Meanwhile, when the heating tank 510 receives a heating-off signal, the microcontroller 330 sends an opening control signal to the switch unit 340. When the switch unit 340 receives the opening control signal, it connects the heating module 500 and the tea-serving module 600. That is, the first valve 530 opens, and hot water flows from the first water outlet 520 into the tea-making cup 610 of the tea-serving module 600. At the same time, the microcontroller 330 sends a start signal to the 555 timing unit 350 to enable the 555 timing unit 350 to start a countdown for the first preset duration, and the first preset duration countdown is the time for the hot water to flow to the tea-serving module 600. When the countdown of the first preset duration ends, the microcontroller 330 sends a closing control signal to the switch unit 340. When the switch unit 340 receives the closing control signal, it disconnects the heating module 500 and the tea-serving module 600 and starts a countdown for the second preset duration. That is, when the water addition is completed, the first valve 530 is closed to disconnect the heating module 500 and the tea-serving module 600 to stop the water addition and start making tea. The second preset duration countdown is the tea-making time (the first steep, 2 s). When the countdown of the second preset duration ends, it indicates that the tea-making is completed. The microcontroller 330 sends a tea-serving control signal to the switch unit 340. When the switch unit 340 receives the tea-serving control signal, it opens the tea-serving module 600. That is, when the tea-making is completed, the second valve 630 is opened to allow the tea soup in the tea-making cup 610 to flow into the fair cup 700, completing the first steep.

[0074] For the end of the first steep, press the start button again to start the second steep. The principles for the second, third, fourth, and fifth steeps are the same as above. The difference is that the water temperature and tea-making time required for each steep are different. When the five steeps are completed, the brewing of the tea is finished. Different teas can be obtained by scanning the code again for soaking.

[0075] In this embodiment, the variety information of the tea is obtained by scanning the code, and the control module 300 controls the heating module 500 to heat the water to the tea-making water temperature suitable for this tea variety, and the control module 300 controls the tea-serving module 600 to perform the appropriate tea-making time for this variety of tea, so that the tea-making machine 100 can select the tea-making water temperature and tea-making time suitable for this tea variety according to different tea varieties, without the need for the user to manually adjust, improving the user experience.

[0076] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
