The clamping plate 51 is used to provide a connection carrier between the mounting frame 5 and the outer casing 1. The first delivery pipe 62 forms a delivery component for delivering cleaning liquid inside the first injection pipe 6 and the second injection pipes 61 under the cooperation of the connection 621. The micro vacuum 7 is used to provide a low-pressure environment inside the outer casing 1. The liquid inlet pipe 13 is used to provide a connecting channel for the bile to enter the outer casing 1.

In addition, a micro water pump is installed on the second delivery pipe 622.

[0025] The bottom of the mounting frame 12 is fixedly connected with a support plate 123; the support plate 123 plays a supporting role.
