[0042] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0043] According to some embodiments of the present application, with reference to FIGS. 1-6, the milk mixing and flushing machine comprises a machine body 100, a milk powder bin 120, a powder blocking assembly 200, a first water tank 130 and a water outlet assembly 300. The machine body 100 is provided with a working area 101 for placing a feeding bottle 110. The milk powder bin 120 is detachably connected to the machine body 100, and is located above the working area 101. The bottom of the milk powder bin 120 is provided with a powder falling opening 122. The powder blocking assembly 200 comprises a blocking plate 210 and a restoring member 220. When the blocking plate 210 is located at a closed position, the blocking plate 210 blocks the powder falling opening 122. When the blocking plate 210 deviates from the closed position, the restoring member 220 applies a biasing force to the blocking plate 210 to move the blocking plate 210 towards the closed position. The first water tank 130 is detachably connected to the machine body 100. The water outlet assembly 300 comprises a water outlet pipe 310, a water pump 320 and a driving member 330 for driving the water outlet pipe 310 to swing. The water pump 320 is connected to the water outlet pipe 310 and the first water tank 130, respectively. When the driving member 330 drives the water outlet pipe 310 to move to a first position, the blocking plate 210 is located at the closed position to block the powder falling opening 122. At this time, the water pump 320 can inject water in the first water tank 130 into the feeding bottle 110 through the water outlet pipe 310. When the driving member 330 drives the water outlet pipe 310 to move to a second position, the water outlet pipe 310 drives the blocking plate 210 to move so that the blocking plate 210 deviates from the closed position. The powder in the milk powder bin 120 falls into the feeding bottle 110 through the powder falling opening 122.

[0044] It can be understood that, with reference to FIGS. 5 and 6, when milk needs to be prepared, the feeding bottle 110 is placed in the working area 101 with the bottle opening of the feeding bottle 110 facing the powder outlet 122, the driving member 330 drives the water outlet pipe 310 to move to the second position, the water outlet pipe 310 drives the baffle 210 to move to open the powder outlet 122 in the process of moving, the reset member 220 applies a biasing force to the baffle 210 to move towards the closed position, the water outlet pipe 310 overcomes the force applied by the reset member 220 to the baffle 210, and the milk powder in the milk powder bin 120 falls downwards into the feeding bottle 110 through the powder outlet 122. Then, the driving member 330 drives the water outlet pipe 310 to move to the first position, at this time, the water outlet of the water outlet pipe 310 faces downwards and is aligned with the bottle opening of the feeding bottle 110, the reset member 220 drives the baffle 210 to move to the closed position again to block the powder outlet 122, the water pump 320 pumps the water in the first water tank 130 to the water outlet pipe 310, and the water in the water outlet pipe 310 flows downwards into the feeding bottle 110. In this process, since the baffle 210 blocks the powder outlet 122, water vapor cannot enter the milk powder bin 120 through the powder outlet 122, so that the milk powder in the milk powder bin 120 is prevented from being damp and deteriorated.

[0045] According to some embodiments of the present application, with reference to FIG. 2, the milk preparation and preparation machine further comprises a second water tank 140, which is detachably connected to the machine body 100.

9. The formula preparation machine according to claim 2, wherein, The body (100) is provided with a receiving cavity (141) and a water inlet channel (142). The second water tank (140) can be placed in the receiving cavity (141). One end of the water inlet channel (142) is connected to the receiving cavity (141) and then to the second water tank (140). When the water outlet pipe (310) moves to the third position, it can be connected to the other end of the water inlet channel (142).

10. A control method, employing a milk preparation machine as described in any one of claims 1 to 9, wherein, The control method includes the following steps: S100: Control the drive component (330) so that the drive component (330) drives the water outlet pipe (310) to move to the second position, and the water outlet pipe (310) overcomes the force of the reset component (220) to drive the baffle (210) to move away from the closed position; S200: Control the drive component (330) so that the drive component (330) drives the water outlet pipe (310) to move to the first position, and the reset component (220) drives the baffle (210) to move to the closed position to block the powder outlet (122); S300: Control the water pump (320) to pump the water in the first water tank (130) to the outlet pipe (310).
