[0002] Severely ill patients need to eat some liquid food to provide nutrition due to their decreased physical functions. Moreover, they cannot eat by themselves and usually need the help of feeding devices to feed them. The most common liquid food feeding device is a liquid food booster.

[0003] The liquid food booster pushes the liquid food into the patient's mouth by squeezing. The liquid food tube for storing the liquid food on the existing liquid food booster is open at one end and closed at the other end. Although this arrangement improves the sealing and facilitates the injection of liquid food, the liquid food tube needs to be cleaned after use. Although a cup brush is used to reach into the liquid food tube for cleaning, there is an angle between the closed end of the liquid food tube and its tube body, and this angle cannot be reached by the cup brush, so there will be a dead corner for cleaning. The existing solution is usually to flush it for a long time on a rapid water faucet, which is not only time-consuming but also has a poor cleaning effect. Therefore, the present application provides a liquid food feeding device to meet the needs. Utility Model Content
