[0029] 1. In the present invention, the tea brewing machine capable of rapid cooling stores water and tea leaves in the water tank and the tea box respectively by opening the top cover and the sealing plug, and then closes the top cover and the sealing plug to seal the water tank and the tea box. When drinking tea is needed, the user puts the teacup into the tea brewing machine housing, just below the tea outlet pipe, and sets the tea drinking temperature and starts the tea brewing operation by operating the control panel. After receiving the control command, the controller controls the cylinder to drive the valve plate to move forward so that the valve plate seals the opposite pipe, controls the switching motor to start and drives the valve core to rotate so that the curved hole is connected to the first water pumping pipe, and then controls the water pump to start, pumps out the water in the water tank, and introduces it into the tea brewing frame through the water inlet pipe and the water outlet pipe. After a certain amount of water is pumped out, the water pump is controlled The controller controls the electric heating rod to open, heats the water in the tea brewing frame, and controls the two servo motors to operate synchronously, driving the two screw rods to rotate synchronously. The screw rods drive the fixing frame and the tea brewing frame to move horizontally through the threaded transmission with the connecting plate, so that the tea brewing frame moves to the bottom of the tea outlet. The conveying motor is then started to drive one of the conveying rollers to operate, and the conveying belt is driven to operate. The conveying belt transports the tea leaves through the conveying protrusions, so that the tea leaves can be transported to the tea outlet, fall into the tea brewing frame, and then enter the tea brewing frame. The flipping motor is then started to drive the mounting shaft and the tea brewing frame to rotate back and forth in a small range, so that the tea leaves are mixed with the hot water, and the electric heating rod is kept open during this period to make the tea.

[0030] 2. In the present invention, the tea brewing machine capable of rapid cooling is described. After the tea is brewed, the servo motor is controlled to drive the tea brewing frame to move to the initial position so that it is located directly above the water receiving frame. Then, the cylinder is started to drive the valve plate to move backward, thereby releasing the closure of the square tube, and the tea leaves are blocked by the tea filter net, so that the tea water falls into the water receiving frame through the square tube. The temperature sensor in the water receiving frame monitors the temperature of the tea water. When the monitored tea water temperature is higher than the set tea drinking temperature, the controller controls the driving motor to start, and the driving motor drives one of the rotating shafts to rotate, and drives the other rotating shaft to rotate through the transmission of the two pulleys. The two rotating shafts drive the two fan blades to rotate, thereby accelerating the air from the rear side of the tea brewing machine housing through the two ventilation holes to the front side, and accelerating the cooling speed of the water falling from the square tube by blowing. At the same time, the flip motor is kept started during this period, and the tea brewing frame is controlled to rotate repeatedly within a small range, so that the square tube swings back and forth, so that the tea water is dispersed and better contacts with the air for cooling;

[0031] 3. In the present invention, the tea brewing machine capable of rapid cooling drives the cone frame to rotate through the rotating shaft, and the rotating frame drives the rotating frame to rotate synchronously and drives a plurality of linkage plates to perform circular motion. The plurality of linkage plates move away from each other under the action of centrifugal force and move to the side away from the fan blades along the direction of the inclined rod. The linkage plate drives the rotating frame to rotate and move backwards, and drives the connecting plate to move backwards through the circular shaft, and presses the control button through the varistor. After the control button is pressed, the water pump is controlled to start, so that the water in the water receiving frame is reintroduced into the tea brewing frame through the second pumping pipe, the water inlet pipe and the water outlet pipe, and then falls from the square pipe to continue cooling until the temperature sensor detects that the temperature of the tea reaches the preset tea drinking temperature, and the controller controls the electric control valve to open, so that the tea pipe discharges the tea and injects it into the teacup to facilitate the user to drink;

[0032] 4. In the present invention, the tea brewing machine capable of rapid cooling is configured to adjust the power of the driving motor according to the difference between the monitored tea temperature and the set tea drinking temperature through a controller. Specifically, when the difference between the monitored tea temperature and the set tea drinking temperature is greater, the power of the driving motor is controlled to be greater, so that the speed of the driving motor is greater, thereby increasing the rotation speed of the two fan blades to increase the wind force, thereby improving the cooling effect on the tea leaves;

[0033] 5. In the present invention, the tea brewing machine capable of rapid cooling drives the cone frame to rotate faster through the rotating shaft, thereby increasing the centrifugal force of the linkage plate, increasing the distance the connecting plate moves backward, and increasing the compression degree of the compression spring, thereby increasing the pressure on the varistor and reducing the resistance. Since the varistor is connected in series with the water pump, the power of the water pump is increased, thereby accelerating the water delivery speed, so as to further improve the cooling rate of the water, so that the user can drink the tea earlier;

[0034] 6. In the present invention, the tea-making machine capable of rapid cooling can realize automatic tea-making through the tea-making mechanism, and can realize cooling of tea through the water supply mechanism and air-cooling mechanism, and can automatically adjust the cooling speed according to the difference between the tea temperature and the preset tea drinking temperature in conjunction with the linkage adjustment mechanism, thereby achieving the effect of rapid cooling of the tea, reducing the user's waiting time, and improving the user's instant drinking experience. The water pump can be automatically started and the power adjusted according to the rotation speed of the fan blades through the cooperation of the control button and the varistor, thereby simplifying the control logic.

After a certain amount of water is extracted, the water pump 5 is controlled to be closed, and the switching motor 507 is controlled to drive the valve core 505 to reset. Then the controller 11 controls the electric heating rod 401 to open, heats the water in the tea brewing frame 4, and controls the two servo motors 408 to operate synchronously, drives the two screw rods 407 to rotate synchronously, and the screw rods 407 drive the fixing frame 8 and the tea brewing frame 4 to move horizontally through the threaded transmission with the connecting plate 406, so that the tea brewing frame 4 moves to the bottom of the tea outlet, and then starts the conveying motor 305 to drive one of the conveying rollers 303 to operate, and drives the conveying belt 304 to operate. The conveying belt 304 realizes the conveying of tea leaves through the conveying protrusion 3041, so that the tea leaves can be conveyed to the tea outlet and fall into the tea brewing frame 4, and then starts the flip motor 405 to drive the mounting shaft 404 and the tea brewing frame 4 to reciprocate in a small range, so that the tea leaves are mixed with hot water, and during this period, the electric heating rod 401 is kept open to realize tea brewing;

[0064] After the tea is brewed, the servo motor 408 is controlled to drive the tea brewing frame 4 to move to the initial position, so that it is located directly above the water receiving frame 7, and then the cylinder 415 is started to drive the valve plate 413 to move backward, thereby releasing the blockage of the square tube 412, and the tea leaves are blocked by the tea filter 402, so that the tea water falls into the water receiving frame 7 through the square tube 412, and the temperature sensor 701 in the water receiving frame 7 monitors the temperature of the tea water. When the monitored tea water temperature is higher than the set tea drinking temperature, the controller 11 controls the drive motor 804 to start, and the drive motor 8 04 drives one of the rotating shafts 802 to rotate, and drives the other rotating shaft 802 to rotate through the transmission of the two pulleys 803, and the two rotating shafts 802 drive the two fan blades 801 to rotate, thereby accelerating the air from the rear side of the tea brewing machine housing 1 to pass through the two ventilation holes to the front side, and accelerating the cooling speed of the water falling from the square tube 412 by blowing air. At the same time, the flip motor 405 is kept started during this period, and the tea brewing frame 4 is controlled to rotate repeatedly within a small range, so that the square tube 412 swings back and forth, so that the tea water is dispersed and better contacted with the air for cooling;

[0065] The cone frame 901 is driven to rotate by the rotating shaft 802, and the rotating frame 903 drives the rotating frame 903 to rotate synchronously and drives the multiple linkage plates 912 to perform circular motion. The multiple linkage plates 912 move away from each other under the action of centrifugal force and move to the side away from the fan blade 801 along the direction of the inclined rod. The linkage plate 912 drives the rotating frame 903 to rotate and moves backward, and drives the connecting plate 904 to move backward through the circular shaft 905, and presses the control button 908 through the piezoresistor 907. After the control button 908 is pressed, the water pump 5 is controlled to start, so that the water in the water receiving frame 7 is re-introduced into the tea brewing frame 4 through the second pumping pipe 503, the water inlet pipe 508 and the water outlet pipe 504, and then falls from the square pipe 412 to continue cooling until the temperature sensor 701 detects that the temperature of the tea reaches the preset tea drinking temperature, and the controller 11 controls the electric control valve to open, so that the tea pipe 702 discharges the tea and injects it into the teacup to facilitate the user to drink;

[0066] The controller 11 adjusts the power of the driving motor 804 according to the difference between the monitored tea temperature and the set tea drinking temperature. Specifically, when the difference between the monitored tea temperature and the set tea drinking temperature is larger, the power of the driving motor 804 is controlled to be larger, so that the speed of the driving motor 804 is larger, thereby increasing the rotation speed of the two fan blades 801 to increase the wind force, thereby improving the cooling effect on the tea leaves;

[0067] The cone frame 901 is driven to rotate faster by the rotating shaft 802, so that the centrifugal force of the linkage plate 912 is increased, the distance that the connecting plate 904 moves backward is increased, and the compression degree of the compression spring 906 is increased, so that the pressure on the varistor 907 is increased and the resistance is reduced. Since the varistor 907 is connected in series with the water pump 5, the power of the water pump 5 is increased, thereby accelerating the water delivery speed, so as to further improve the cooling rate of the water, so that the user can drink the tea earlier;

[0068] After the tea is brewed, the controller 11 controls the servo motor 408 to drive the tea brewing frame 4 to move to the top of the residue receiving frame 6, and the flip motor 405 drives the tea brewing frame 4 to flip, so that the tea waste residue is poured into the residue receiving frame 6 for collection, and the tea residue is separated into solid and liquid through the filter residue net 601 to avoid odor and deterioration.
