A plurality of openings are arranged on the lower side of the inner cylinder 4, and the cleaning mixture sprayed onto the dental tray by the spherical nozzle 17 flows into the outer cylinder 2 through the openings.

[0027] The outer cylinder 2 is a cylindrical barrel which is gradually lowered from the outside to the inside and is tilted inside the shell 1. The opening side of the outer cylinder 2 is higher than the other side. The water collecting tank 3 is a rectangular tank body which is flat on the top and inclined on the bottom. The upper side is provided with an opening. The side of the water collecting tank 3 which is away from the opening is lower than the opening side. The water collecting tank 3 is arranged on the lower side of the outer cylinder 2. The side wall of the lower end of the outer cylinder 2 is provided with a channel connected to the opening on the upper side of the water collecting tank 3. The cleaning mixture in the outer cylinder 2 flows into the water collecting tank 3 through the channel.

[0028] The power device includes a motor 10, a motor fixing seat 11 and a motor fixing block 12. The two motor fixing blocks 12 are arranged parallel to each other on the upper side of the water collecting tank 3. The two motor fixing blocks 12 are arranged on one side of the bottom plate of the outer cylinder 2 and are symmetrically arranged with respect to the axis of the outer cylinder 2. The motor fixing seat 11 is arranged between the two motor fixing blocks 12, and the motor 10 is installed on the motor fixing seat 11. The fixed sleeve 8 is fixed to the bottom plate of the outer cylinder 2 by bolts, and the bearing 7 is arranged in the fixed sleeve 8 and connected to the rotating shaft 5. A Y-shaped sealing ring 24 is arranged between the bearing 7 and the bottom plate of the outer cylinder 2 to prevent water from flowing out through the through hole on the outer cylinder 2. The rotating shaft 5 passes through the through hole of the outer cylinder 2, and one end is matched and connected with the bearing 7, and the other end is connected with the motor 10 through the coupling 9.

[0029] The filtering structure includes a processing drawer 13, and guide rails 14 with gradually increasing thickness from the outside to the inside are arranged on both sides of the water collecting tank 3. The processing drawer 13 is slidably mounted on the guide rails 14, and a mesh water outlet 15 connected to the water collecting tank 3 is arranged on the bottom plate of the processing drawer 13. The lower side of the water collecting tank 3 is connected to the water outlet pipe 6, and all the cleaning mixture flowing down from the outer cylinder 2 falls into the processing drawer 13, and the cleaning water flows into the lower end of the water collecting tank 3 through the water outlet 15, and then flows out of the cleaning machine through the water outlet 15. The cleaned impression material remains on the processing drawer 13, and the processing drawer 13 is taken out to clean the residue after cleaning.

[0030] The drawer cover of the processing drawer 13 covers the opening of the water collecting tank 3, and a magnetic drawer lock assembly 16 is set at the same position on the drawer cover and the upper side of the inner plate of the water collecting tank 3. When the processing drawer 13 enters the water collecting tank 3 along the guide rail 14, the magnetic drawer lock assembly 16 is attracted to lock the processing drawer 13.

The outer panel of the door panel 19 covers the entrance of the outer cylinder 2, and the inner panel of the door panel 19 blocks the entrance of the outer cylinder 2. A rubber strip 20 is arranged around the inner panel to prevent the cleaning mixture from overflowing during the rotation of the inner cylinder 4. A hinge 21 is arranged on one side of the door panel 19 to connect with one side of the housing 1, and a magnetic door lock assembly 22 is arranged on the other side of the door panel 19 to connect with the other side of the housing 1. The door panel 19 swings up and down along the hinge 21. When the other side of the door panel 19 contacts the housing 1, the door panel 19 is attracted by the magnetic door lock assembly 22.

[0032] Working process:

[0033] During clinical use, first open the door panel 19, then place the dental tray to be cleaned into the inner cylinder 4, close the door panel 19, and then the magnetic door lock assembly 22 is closed. After clicking the run switch, the motor 10 works, driving the inner cylinder 4 to rotate, thereby driving the dental tray to rotate in the inner cylinder 4. At the same time, the external water source enters the water inlet pipe 18, and the water is evenly sprayed on the dental tray through the spherical nozzle 17. After the inner cylinder 4 rotates and the spherical nozzle 17 is flushed, the impression material fixed on the dental tray is cleaned and falls to the bottom of the processing drawer 13. The sprayed water directly flows into the water collection tank 3 through the mesh water outlet 15 at the bottom of the processing drawer 13, and is discharged through the water outlet pipe 6. After cleaning, open the door panel 19 and take out the cleaned dental tray. Then, pull out the processing drawer 13, pour the fallen impression material into the waste bucket, and finally put the processing drawer 13 back into the water collection tank 3.
