DETAILED DESCRIPTION

[0025] The utility model will be further described in combination with the drawings and specific implementation schemes:

The tea barrel 2 is used for containing tea water, that is, tea leaves and hot water can be put into the tea barrel 2, so as to realize tea leaf brewing and obtain tea water.

[0027] The water tank 7 is fixedly or detachably installed in the inside of the tea machine box 1, the water inlet electromagnetic valve 9 is installed on the water tank 7, and the output end of the water inlet electromagnetic valve 9 is connected in communication with the inside of the water tank 7, and the input end of the water inlet electromagnetic valve 9 is used to be connected in communication with the external water source, for example, connected in communication with the external water source (such as a bucket of water) through a hose, so as to deliver the drinking water into the water tank 7.

[0028] The heating assembly is installed in the water tank 7, and is used to heat the drinking water in the water tank 7.

[0029] The water pump 8 is further included, which is installed on the water tank 7, for example, installed on the outer wall of the water tank 7. The input end of the water pump 8 is connected in communication with the inside of the water tank 7, the output end of the water pump 8 is connected in communication with the input end of the flow meter 11, the output end of the flow meter 11 is connected in communication with the input end of the instant heater 5, the output end of the instant heater 5 is connected in communication with the input end of the lifting water outlet assembly 4, and the output end of the lifting water outlet assembly 4 is connected in communication with the tea outlet nozzle of the tea barrel 2, so as to input the drinking water into the tea barrel 2, so that the drinking water is mixed with the tea leaves pre-stored in the tea barrel 2 and is brewed, so as to obtain the tea water.

[0030] The instant heater 5 is used to reheat the water flowing out of the water tank 7, and deliver the heated drinking water into the tea barrel 2. That is, the drinking water in the tea barrel 2 is heated twice. The flow meter 11 is used to measure the current water flow rate flowing into the tea barrel 2.

[0031] The flow meter 11 is connected with the instant heater 5 together, and forms a flow heating assembly, which is fixedly or detachably installed in the inside of the tea machine box 1. The lifting water outlet assembly 4 and the controller 6 are both installed in the inside of the tea machine box 1.

[0032] The controller 6 is electrically connected with the lifting water outlet assembly, the instant heater 5, the flow meter 11 and the water pump 8 respectively, and controls the opening and closing and working time length of the lifting water outlet assembly, the instant heater 5 and the water pump 8 based on the flow signal received from the flow meter 11, the flow signal representing the current flow size of the drinking water flowing through the flow meter 11. For example, the controller 6 controls whether the instant heater 5 needs to be started to heat the drinking water and maintains the heating time length. Similarly, whether the water pump 8 needs to be started to deliver the drinking water into the tea barrel 2 and maintains the starting time length can be controlled.

When the tea caddy 2 is placed on the weighing assembly 3, the tea caddy 2 can contact the extension, that is, the gravity of the tea caddy 2 can act on the scale pan support 31, and the gravity of the tea caddy 2 acts on the strain gauge 32 through the extension, so that the strain gauge 32 deforms. Different degrees of deformation of the strain gauge 32 are caused by different sizes of gravity, that is, a mapping relationship between the deformation and the gravity is established, so the gravity can be measured according to the degree of deformation, thereby completing the weighing.
