The cold water in the water tank 10 is pumped into the heater 7 through the water pump 17 and heated, and then the hot water is detected by the NTC temperature sensor 6 in the pipeline. If the temperature meets the brewing standard, it is controlled by the solenoid valve V1 5 and injected into the transparent glass brewing chamber through the interface A. 2. If the temperature does not meet the brewing standard, it will be controlled by the solenoid valve V1 5 and discharged as waste water through interface C.

The vacuum extraction function of this brewing system is that the air in the transparent glass brewing chamber 2 is sucked away by the vacuum pump 12 through the solenoid valve V2 15 and discharged through the solenoid valve V3 18. The vacuum degree of the transparent glass brewing chamber 2 is controlled by the control board The working time of the vacuum pump 12 is completed.

In order to allow the tea leaves to be fully heated in hot water, the brewing system adopts air-assisted circulation in the design, that is, a bottom air inlet 30 is provided on the lower side of the detachable filter screen 25 of the tea seat 1. When the transparent glass brews When the chamber 2 is in a vacuum state, the electromagnetic valve V4 13 is opened, and then the air is naturally sucked into the transparent glass brewing chamber 2 through the electromagnetic valve V4 13, and rising bubbles are generated. At the same time, the tea liquid and leaf bodies in the transparent glass brewing chamber 2 will circulate up and down continuously, making the temperature and extraction more uniform.

The tea seat 1 of this brewing system is provided with a detachable water outlet valve 29, and the valve body is made up of a valve head 26 made of silica gel, a valve head spring 27 and a valve seat 28. Under the action of elastic force, the bottom of the tea holder 1 is sealed.

Working principle: During operation, the user first puts tea leaves in the detachable filter 25 of the tea holder 1, and then installs it on the transparent glass brewing chamber 2.

First start the vacuum pump 12 and the electromagnetic valve V2 15, at this moment the air in the transparent glass brewing chamber 2 will be sucked away by the vacuum pump 12 through the intake and exhaust pipe 3 and the electromagnetic valve V2 15, and will be drawn from the exhaust port of the vacuum pump 12 through the pipeline from the electromagnetic Port B of the valve V3 18 enters the solenoid valve and exits from its port C.

After the vacuum is completed, the solenoid valve V2 15 and the vacuum pump 12 are closed, and the water pump 17 pumps water to the heater 7, and then the hot water flows through the solenoid valve V1 5. When the NTC temperature sensor 6 at the port B of the solenoid valve V1 5 detects that the water temperature does not meet the standard Timing, the hot water is discharged from the solenoid valve V1 5 port C, if the hot water is detected to meet the calibration, the hot water flows into the transparent glass brewing chamber 2 from the solenoid valve V1 5 port A until the water volume reaches the set value.

When the tea leaves are infiltrated for a certain period of time, the electromagnetic valve V4 13 is opened. At this time, the external air will be sucked into the transparent glass brewing chamber 2 by negative pressure, and a large number of steam drums will be formed to lift the infiltrated tea leaves upward. Start the solenoid valve V2 15 and the vacuum pump 12 again in the open state to form a continuous bubble circulation in the transparent glass brewing chamber 2. When the set time is reached, the air intake is closed, and the transparent glass brewing chamber 2 is pumped into negative pressure again state.

After the tea leaves stand under negative pressure, start the vacuum pump 12 and the solenoid valve V3 18. At this time, the external air will enter the valve body through the interface C of the solenoid valve V2 15 and enter the vacuum pump 12 through the interface B, and then the air will be pumped to the solenoid valve. V3 18 and reaches the transparent glass brewing chamber 2 through the intake and exhaust pipes 3, the water outlet valve 29 at the bottom of the tea seat 1 is pressed open under the continuous pressure supply, and the tea liquid is discharged immediately, and the brewing process is completed.
