When it is necessary to clean the refrigeration crystals in the feed pipe 140, the threaded rod 240 is rotated to drive the connecting block 230 to slide in the slide groove 220, and then the telescopic cylinder 250 is driven to move and move it to the bottom of the feed pipe 140. At this time, the power switch is turned on, the output shaft of the servo motor 260 rotates to drive the scraper 270 to rotate, and the telescopic cylinder 250 drives the servo motor 260 to the feed pipe 140 by extending and retracting the telescopic end. The scraper 270 moves in the pipeline and rotates to break and scrape the refrigeration crystals in the discharge pipe 140, thereby cleaning the refrigeration crystals in the pipeline. This can prevent the refrigeration crystals from clogging the pipeline and affecting the use and working effect of the refrigerant preparation device. When the cleaning is completed, the threaded rod 240 is rotated in the opposite direction to move the servo motor 260 and the scraper 270 to the placement tube 310 through the telescopic cylinder 250, and the refrigeration crystals remaining on the scraper 270 are cleaned by the brush 320 to prevent them from adhering to the scraper 270 and affecting the cleaning effect of the discharge pipe 140 in the future.
