[0035] The protective box 3 is equipped with a cleaning component corresponding to the extraction tube 2 inside.
[0036] The cleaning assembly includes a connecting box 6 embedded at the bottom of the protective box 3. A cleaning and disinfection pipe 7 is embedded in the right side wall of the connecting box 6. The inlet end of the cleaning and disinfection pipe 7 is connected to an external steam pipe, and the outlet end of the cleaning and disinfection pipe 7 faces the outlet end of the extraction pipe 2. Ultraviolet sterilization lamps 8 are fixedly installed on the front and rear inner walls of the protective box 3.
[0037] It is worth noting that after milk collection, high-temperature steam is supplied to the end of the extraction tube 2 through the cleaning and disinfection tube 7, which can achieve the effect of cleaning and sterilizing the end of the extraction tube 2. In addition, during subsequent storage, the extraction tube 2 is continuously sterilized and protected by the ultraviolet sterilization lamp 8 to avoid secondary contamination and ensure the safety of the extraction tube 2 during use.
[0038] The bottom of the connecting box 6 is fitted with a drain pipe 9, and the outlet end of the drain pipe 9 is connected to the external sewer pipe.
