[0033] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0034] According to some embodiments of the present application, referring to FIGS. 1-3, the powder bin structure includes a powder storage bin 100, a powder falling bin 200, a stirring assembly 300, and a powder blocking assembly 400. The axial direction of the powder storage bin 100 is the up-down direction, and the bottom of the powder storage bin 100 is provided with a powder falling channel 110, which is coaxially arranged with the powder storage bin 100. The powder falling bin 200 is located below the powder storage bin 100 and is detachably connected to the powder storage bin 100. The bottom of the powder storage bin 100 is provided with a powder falling port 210, and the powder falling channel 110 is in communication with the powder falling port 210. The stirring assembly 300 is arranged in the powder storage bin 100, and the stirring shaft 310 of the stirring assembly 300 extends in the up-down direction. The stirring assembly 300 can be driven to rotate around the stirring shaft 310. The lower end of the stirring shaft 310 is provided with an arch breaking structure 321, and the arch breaking structure 321 is partially inserted into the powder falling channel 110. The powder blocking assembly 400 is used to block or open the powder falling port 210.

[0035] When the powder needs to fall, the powder blocking assembly 400 opens the powder falling port 210, and the milk powder in the powder storage bin 100 falls downward through the powder falling channel 110 and the powder falling port 210 in turn. The milk powder may form an arch in the falling channel and at the entrance of the falling channel. During the rotation of the stirring shaft 310, the arch breaking structure 321 can break the arch of the milk powder to ensure that the milk powder in the powder storage bin 100 can smoothly pass through the powder falling channel 110. At the same time, since the stirring shaft 310 is coaxially arranged with the powder storage bin 100, the milk powder in the powder storage bin 100 is concentrated from the periphery to the center, and the falling efficiency is faster than that of the traditional milk powder which needs to move to the powder grid around. Moreover, the powder storage bin 100 and the powder falling bin 200 are detachably connected, which facilitates mutual separation for separate cleaning, and facilitates cleaning of the powder falling port 210 and the falling channel.

One end of the stirring blade 320 is fixedly connected with the stirring shaft 310, and the plurality of stirring blades 320 are distributed in the circumferential direction of the stirring shaft 310.

[0038] Further, referring to FIG. 2, the stirring blade 320 is close to the tapered wall 122, so that the stirring blade 320 can sweep the tapered wall 122 under the rotation of the stirring shaft 310, avoiding the milk powder from adhering to the tapered wall 122.

[0039] According to some embodiments of the present application, referring to FIG. 2 and FIG. 3, the first support 330 is arranged in the powder storage bin 100 and extends in the horizontal direction, the inner wall of the powder storage bin 100 is provided with two clamping grooves 130, the two ends of the first support 330 are respectively clamped and connected with the two clamping grooves 130, and the stirring shaft 310 penetrates and is rotationally connected with the first support 330.

It can be understood that when the first powder outlet cylinder 140 is inserted downward into the second powder outlet cylinder 220, the protruding portion 150 passes through the first groove 231, and then the first powder outlet cylinder 140 is rotated relative to the second powder outlet cylinder 220, so that the protruding portion 150 moves relative to the second groove 232, and the protruding portion 150 moves to the other end of the second groove 232 and the buckle portion 240, the buckle portion 240 has elasticity, when the protruding portion 150 passes through the buckle portion 240 to be located between the buckle portion 240 and the other end of the second groove 232, the buckle portion 240 cooperates with the second groove 232 to limit the rotation of the protruding portion 150 relative to the second powder outlet cylinder 220, so as to relatively fix the powder storage bin 100 and the powder falling bin 200.

In the initial state, the powder blocking plate 410 blocks the powder falling opening 210. When an external force is applied to the powder blocking plate 410 to rotate the powder blocking plate 410 to open the powder falling opening 210, the torsion of the reset member 420 needs to be overcome. When the external force is cancelled, the powder blocking plate 410 is driven by the reset member 420 to block the powder falling opening 210 again.
