[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0026] As Figure 1As shown in the figure, the present invention provides a fully automatic tea brewing device, which includes a tea leaf canister 1, a hot water canister 2 and a tea brewing cylinder 3. A tea leaf outlet is provided at the lower part of the tea leaf canister 1. When the tea brewing cylinder 3 rotates to the position of the tea leaf canister 1, the inlet 4 is aligned with the tea leaf outlet to ensure that tea leaves can fall into the tea brewing cylinder 3. The tea brewing cylinder 3 is of a fan-shaped structure. An inlet 4 is provided on the arc surface of the tea brewing cylinder 3, and a water outlet pipe 5 is provided at the center of the circle. A fixing part 9 is provided at the center position of the tea brewing cylinder 3, and the water outlet pipe 5 is inserted into the fixing part 9. A water leakage port 12 is provided at the upper part of the fixing part 9, and a central axis water outlet 10 is provided on the water outlet pipe 5. When the tea brewing cylinder 3 is aligned with the hot water canister 2, the central axis water outlet 10 is aligned with the water leakage port 12. When the water outlet pipe 5 rotates to the position of the tea leaf canister 1, the central water outlet is not corresponding to the water leakage port 12. Only when it is at the lower part of the hot water canister 2, the water leakage port 12 and the central axis water outlet 10 are corresponding, and the brewed tea can be discharged from the water outlet pipe 5. An electromagnetic valve 8 is provided on the water outlet pipe 5 to control the opening and closing. In order to prevent the tea leaves in the tea brewing cylinder 3 from falling into the water outlet pipe 5, a filter screen 11 is provided in the tea brewing cylinder 3.

[0027] An outlet end 7 is provided at the lower part of the hot water canister 2, and an arc-shaped sealing cover 6 is connected to the lower part of the outlet end 7. When the tea brewing cylinder 3 rotates along the water outlet pipe 5, it is pressed against the arc-shaped sealing cover 6 to seal the inlet 4. The shape of the arc-shaped sealing cover 6 is the same as the shape of the arc side of the tea brewing cylinder 3. When the tea brewing cylinder 3 rotates, it just cooperates with the arc-shaped sealing cover 6 to close the opening of the tea brewing cylinder 3 and reduce the heat loss during tea brewing. The outside of this device is provided with a machine shell. A high-pressure nozzle 13 is provided at the lower part of the tea brewing cylinder 3, and the high-pressure nozzle 13 is arranged at the bottom of the machine shell to blow away the tea dregs.

[0028] The working mode of this tea brewing device is as follows: When the tea brewing cylinder 3 rotates to the upper left inclined position, the tea leaves in the tea leaf canister 1 fall into the tea brewing cylinder 3. The tea brewing cylinder 3 continues to rotate clockwise to the directly above, the hot water valve is opened, and after the water is filled, the hot water valve is closed. At this time, tea brewing starts. After reaching the set tea brewing time, the tea water outlet electromagnetic valve 8 is opened to discharge the tea water. The tea brewing cylinder 3 rotates to the directly below, and at this time, the cylinder mouth faces down to pour out the tea dregs. Then the high-pressure gas nozzle is opened to blow away the tea dregs that adhere to it and have not fallen.

[0029] A fully automatic tea brewing system includes a single-chip microcomputer chip. A tea leaf dropping module, a power supply module, a tea brewing module, a water heater control module and a display control module are connected to the single-chip microcomputer chip, and the tea leaf dropping module...

[0030] A control method for a fully automatic tea brewing device includes the following steps:

[0031] S1: Tea leaf dropping. By rotating the tea brewing cylinder 3 to the position of the tea leaf canister 1, the tea leaves fall into the tea brewing cylinder 3;

[0032] S2: Fill with water, drive the tea brewing cylinder 3 to continue rotating to the lower part of the hot water tank 2, and align the water outlet of the hot water tank 2 with the inlet 4 of the tea brewing cylinder 3. At the same time, the arc-shaped sealing cover 6 seals the inlet 4.

[0033] S3: Brewing, open the solenoid valve 8 of the hot water tank 2, and hot water enters the tea brewing cylinder 3. Control the brewing time through the timer.

[0034] S4: Tea serving, open the solenoid valve 8 of the water outlet pipe 5 to control the water discharge.

[0035] S5: Residue discharging, drive the tea brewing cylinder 3 to continue rotating until the inlet 4 is downward, and the high-pressure nozzle 13 at the lower part jets air towards the inlet 4 to blow out the tea residues.

[0036] This device can preset various tea types of modes in advance. When making tea, just click a button to complete the whole tea-making process. For each type of tea made, an independent mode can be set separately; it has an automatic cleaning function. After switching the tea-making mode, it will be automatically cleaned. It is also equipped with a Bluetooth module or a Wi-Fi module to connect the tea maker to the mobile phone and has functions such as playing music.

[0037] Various modifications to the embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
