TECHNICAL FIELD

[0001] The present application relates to the technical field of beverage preparation devices, in particular to a top water injection type beverage brewing device and a control method thereof. BACKGROUND

[0002] Newborns need to be fed several times at night, and caregivers need to get up to prepare milk powder. The process of preparing milk powder includes: 1. heating cold water or cooling hot water to a suitable drinking temperature; 2. pouring a certain amount of water into a feeding bottle; 3. taking a certain amount of milk powder and putting it into the feeding bottle; 4. shaking the feeding bottle to mix the milk powder and water evenly. This series of processes not only consumes time, but also makes it difficult for caregivers to fall asleep. In view of this problem, some beverage brewing devices for brewing milk powder have appeared on the market.

[0003] For example, the patent document with the authorization announcement number CN218552085U discloses a milk powder brewing device for automatically brewing milk powder. The milk powder brewing device includes a main body, a water tank, a shaking assembly, and a powder box assembly, the powder box assembly is arranged in a containing groove; the powder box assembly includes an outer shell, an inner shell, and a driving member, the inner shell is arranged in the outer shell, the inside of the inner shell is divided into at least two cavities for placing milk powder, the lower part of the inner shell is provided with powder outlets corresponding to the at least two cavities and communicating with the at least two cavities, the powder outlets are provided with blocking members, the bottom of the outer shell is provided with an outlet, the outlet is opposite to the bottle opening of the feeding bottle, the driving member is arranged in the containing cavity and connected with the inner shell through the outer shell; when the driving member drives the inner shell to rotate in the outer shell, the blocking members are pushed open, and the powder outlets are rotated to be aligned with the outlet, so that the milk powder in the cavities falls into the feeding bottle. When using, the milk powder is pre-added into different cavities in the powder box assembly, then the powder box assembly is placed in the containing groove, and then the inner shell is driven to rotate in the outer shell by the driving member, so that the blocking members for blocking the powder outlets are pushed open by the protrusions, and when the powder outlets are rotated to be aligned with the outlet, the milk powder placed in the cavities falls into the feeding bottle through the powder outlets and the outlet, that is, the amount of milk powder for one time is completed, and then the water in the water tank is introduced into the feeding bottle through the water pump, so that the automatic brewing of the milk powder is completed.

[0004] The above-mentioned milk powder brewing device has the following problems in use.

[0005] 1. Powder floating problem: when using the milk powder brewing device, the bottle opening of the feeding bottle needs to be away from the outlet of the outer shell, otherwise it will be difficult to take out the feeding bottle due to interference, and the distance between the bottle opening and the outlet of the shell will cause the milk powder to float out of the feeding bottle, which not only causes waste of milk powder, but also causes the floating milk powder to stick to the feeding bottle, the milk powder brewing device, and even the table, which is difficult to clean.

[0006] 2. The problem of powder sticking: the powder box assembly is composed of an outer shell and an inner shell, and the chamber for placing milk powder is arranged on the inner shell. An outlet for communicating with the chamber is arranged on the inner shell. This structure can cause the milk powder to fall into the gap between the outer shell and the inner shell during the powder falling process. Meanwhile, the residual powder can be brought into the gap between the outer shell and the inner shell by the rotation of the inner shell, resulting in powder sticking.

[0007] 3. The problem of powder sticking at the outlet: the milk powder in each independent chamber needs to fall into the feeding bottle through the common outlet on the outer shell. The common outlet is prone to sticking milk powder, and the stuck milk powder is prone to damp clumping or even deterioration, which can contaminate the milk powder passing through next time.
