[0026] The working principle of this utility model:
[0027] Water is added to the water storage tank 301 through the inlet 302, and a measured amount of tea leaves are placed into the steeping tank 202. The vacuum assembly 1 is then placed above the support plate 201. At this time, the output of the water pump 303 draws water from the water storage tank 301 into the steeping tank 202 through the pump pipe 304. As the water level rises, the level gauge 205 rises. Once it reaches the designated position, the level gauge 205 defines this signal as a standard signal and sends it to the controller 106. The controller 106 receives the signal and controls the water pump 303 to stop working. The heating coil 203 then provides heat to the steeping tank 202. The output of the air pump 107 extracts air from the outer casing 101, creating a vacuum inside the device. After the device has been working for a period of time, the output of the multi-stage electric actuator 501 lowers the lower components. The process involves extracting the steeped tea water into the sampling tube 504. After extraction, the output end of the multi-stage electric actuator 501 drives the lower component to rise. Once it reaches a certain position, the output end of the drive motor 406 drives the second gear 407 to rotate. The rotation of the second gear 407 drives the meshing first gear 405 to rotate. The rotation of the first gear 405 drives the threaded rod 402 to rotate. The rotation of the threaded rod 402 drives the threaded moving block 404 to move horizontally, thus sending the sampling tube 504 above the tea polyphenol detector 6. The output end of the multi-stage electric actuator 501 drives the lower component to descend, thus pouring the water in the sampling tube 504 into the tea polyphenol detector 6 for analysis. The analysis results are displayed on the display of the tea polyphenol detector 6.
