[0026] A pressure sensor 8 is fixed on the upper side of the outer wall of the storage box 7, and the sensor head of the pressure sensor 8 is arranged upward, opposite to the lifting plate 6. In the present embodiment, the lifting plate 6 is supported and lifted by a cylinder (not shown in the drawing) at the bottom end of the vertical frame 1, and a hole (not shown in the drawing) is provided on the storage box 7 for the cylinder to be fixed to the bottom end of the vertical frame 1 and located outside the storage box 7 at the same time.

[0027] When the test tubes are not cleaned and dried, the lifting plate 6 is at the lowest position in the stand 1, the jet pump 10 is in a stopped state, the scraper 15 and the scraper 2 16 are located between the cylinder 5 and the fixed column 4 and are in contact with the cleaning sponge at the upper end of the inner wall of the cylinder 5 and the cleaning sponge at the upper end of the outer wall of the fixed column 4 respectively, and one end of the lower side of the lifting plate 6 is located on the upper side of the pressure sensor 8, which constantly detects the pressure on the lifting plate 6. In the utility model, the pressure sensor 8 serves as a limiter to prevent the lifting plate 6 from descending too low, and cooperates with the cylinder to make the lifting plate 6 descend to a suitable position and stop.

[0028] When the test tube is installed on the test tube positioning plate 3 and needs to be cleaned, the cylinder will drive the lifting plate 6 to move vertically upward. During the vertical upward movement of the lifting plate 6, the protective shell 18 will be driven to slide, and at the same time, the lifting plate 6 drives the fixed column 4 to move vertically upward synchronously through the linkage plate 19, so that the cleaning sponges of the cylinder 5 and the fixed column 4 respectively clean the outer wall and inner wall of the test tube, absorb excess moisture and wipe off impurities, and then the cylinder moves downward. At this time, during the downward movement of the cylinder, the scraper 15 and the scraper 2 16 will gradually squeeze and scrape the cleaning sponge in the cylinder 5 and the fixed column 4 from bottom to top, and the clean sea The moisture absorbed in the cotton and the impurities attached to the surface will be cleaned up and enter the storage box 7 from the opening 23 for storage. When the scraper 15 and the scraper 2 16 respectively scrape to the lower ends of the cylinder 5 and the fixed column 4 and are located below the jet pipe 1 11 and the jet pipe 2 12, the personnel can control the jet pump 10 to start through the control system, and the jet pump 10 starts to supply air to the jet pipe 1 11 and the jet pipe 2 12. The jet pipe 1 11 and the jet pipe 2 12 start to spray the upper ends of the scraper 15 and the scraper 2 16 to remove the moisture and impurities on the scraper 15 and the scraper 2 16.

[0029] When the lifting plate 6 rises, scraper 1 15 and scraper 2 16 will still squeeze the cleaning sponge on the cylinder 5 and the fixed column 4 from top to bottom, but moisture impurities will be located between the inner wall of the cylinder 5 and scraper 1 15 and between scraper 2 16 and the fixed column 4, and flow into the storage box 7 through hole 13 and hole 2 14.

[0030] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
