[0002] An existing powder distribution device is used to distribute powder in an extraction container and then take it for extraction. It includes a driving mechanism, a powder storage chamber, a powder feeding channel and a powder distribution component. The powder distribution component includes a main body, and a rotating matching part is provided on the periphery of the main body. The driving mechanism is in transmission cooperation with the rotating matching part. A powder inlet is provided on the upper side of the main body, and a powder outlet is provided on the lower side of the main body. The powder outlet is centrally arranged along the main body, and a powder distribution channel is formed between the powder inlet and the powder outlet. The powder distribution rod is arranged on the lower side of the main body and spans the powder outlet. The powder feeding channel is connected between the powder placement chamber and the powder inlet. During the powder distribution process, the extraction container is placed on the main body. Below the body, the driving mechanism drives the main body to rotate along its central axis, and the powder in the storage chamber enters the powder inlet through the powder feeding channel, then enters the powder distribution channel from the powder inlet, and then enters the extraction container from the powder inlet, and the powder in the extraction container is scraped by the powder distribution rod to make it evenly distributed.

[0059] refer to Fig.13 , 14In the other embodiment 2 of the powder distribution component 100 of the present invention, the difference between it and the preferred embodiment of the powder distribution component 100 of the present invention is that the connection method between the cover body 5 and the powder distribution device 10 is different. Specifically, the powder distribution component 100 of the present invention also includes a bearing 103, and the bearing 103 includes an inner bearing ring 1031 and an outer bearing ring 1032. The inner bearing ring 1031 is sleeved on the outside of the side wall 14, and the outer bearing ring 1032 is fixedly connected to the cover body 5.

[0060] The working principle of the powder distribution component 100 of the present invention is as follows: the powder distribution component 100 is assembled on a beverage device that can distribute powder, the driving mechanism of the beverage device that can distribute powder is engaged with the gear teeth 131 of the transmission member 13, the beverage device that can distribute powder is started, the powder pressing portion 2 extends into the extraction container, and at the same time, the driving mechanism drives the powder distributor 10 to rotate, the grinding module transports the completely ground powder from the powder inlet 52 to the powder chamber 31, and then enters the extraction container from the powder inlet 52 through the powder lower channel 32. During the rotation of the powder distributor 10, the powder scraping portion 212 will promptly scrape the accumulated powder coming out of the powder outlet 211 so that the powder is evenly distributed throughout the extraction container. At the same time, the powder pressing surface 213 presses down the powder in the extraction container until the powder distribution is completed.

[0061] The beneficial effects of the technical solution of the present invention are as follows: by arranging the powder outlet to be located between the center of the bottom wall and the edge of the bottom wall, the powder scraping part extends from the center of the bottom wall to the edge of the side wall, and when the powder distributor performs powder distribution work, the powder distributor rotates along the rotating axis, and the powder entering the powder chamber enters the extraction container through the powder outlet. During the rotation of the powder distributor, the powder scraping part will promptly flatten the powder accumulated out of the powder outlet so that the powder is evenly distributed throughout the extraction container to avoid the powder outlet being blocked and affecting the powder discharge speed of the powder outlet. At the same time, by arranging the powder scraping part to protrude downward from the powder outlet, after the powder is evacuated by the powder scraping part, a space is maintained between the powder in the extraction container and the powder outlet, so that the powder discharges continuously and uninterruptedly from the powder outlet to ensure the powder discharge speed.

[0062] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
