Brewing operation:

the following description will be made by taking 100ml of brewing material liquid as an example: the operator removes the lid of the cup 20, then puts the cup 20 on the tray 16, and presses the lower key C, so that the control device 17 can know through analysis that the material taking rod 50 in the material taking device needs to be regulated and controlled to run 4 times, namely, the material taking is carried out 4 times, and the material taking rod is soaked in 100ml of water. The control device 17 specifically controls the one-key brewing operation as follows: the control device 17 regulates and controls the starting pump a to add 30-50 ml of water into the blending device, the blending device is started, then the material taking rod 50 is regulated and controlled to take the material for 4 times, after the material taking is finished, the pump a is started again to add the residual amount of water into the blending device, then the material powder is fully dissolved through mixing, and the blending device is stopped after blending. Because the aforesaid has put cup 20 on saddle 16, consequently cup 20 can be detected to sensor c, controlling means 17 can start pump b and adjust the a way export of three-way valve and be in the conducting state (if can't detect cup 20, then controlling means 17 can't start pump b and open the a way of three-way valve to adjust voice device and report voice prompt operating personnel and put into cup 20), move the feed liquid in the mixing device to cup 20, then regulate and control voice device and report voice prompt information, suggestion operating personnel takes off cup 20.

The material taking operation of the material taking rod 50 is as follows: at the beginning, the material taking rod 50 is at the material taking position, and the air cylinder A adjusts the rod B to move out of the material storage barrel 40, so that the material taking groove 51a is arranged corresponding to the tank opening of the mixing tank 60. Then the driving mechanism B (driving motor 37) adjusts the bar B to turn 180 degrees so that the material taking bar 50 is at the material discharging position, so that the material powder is poured into the mixing tank 60, then the driving mechanism B adjusts the material taking bar 50B to turn 180 degrees again, then the air cylinder A is started to adjust the material taking bar 50 to be inserted into the material storage barrel 40 to take the material again, and the operation is repeated for 4 times so as to finish the material taking.

The housing 10 may be made of injection molded parts, the housing 10 is mainly used for mounting the devices, the arrangement state and the position relationship of the devices in the housing 10 are shown in fig. 2, the mounting and fixing between the devices and the housing 10, which are not described in detail in the present invention, may be bolt assembly, snap assembly, plug assembly, injection molding, adhesive bonding, etc., and these conventional connection manners may all achieve the mounting and fixing between the devices and the housing 10.
