[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6 This utility model provides the following technical solution: a medical and nursing waste recycling device, comprising a recycling device body, the recycling device body including a recycling box 1, a recycling trough 10, a drive mechanism 4, and a shielding component 5. A cavity 9 is provided at the bottom inner side of the recycling box 1, and the recycling trough 10 is provided at the top of the cavity 9. An electric heating wire 11 is embedded in the bottom surface of the recycling trough 10. The drive mechanism 4 is inserted into the top of the recycling box 1, and the shielding component 5 is sleeved on the surface of the drive mechanism 4. A slag removal mechanism 6 is connected to the bottom end of the drive mechanism 4, and the end of the slag removal mechanism 6 is used to fit against the inner wall of the recycling trough 10. This recycling device is used for a two-stage recycling process of medical and nursing waste.

[0026] In use, this invention allows users to choose between manually opening the cover 13 or opening it via the drive mechanism 4 by controlling the connection between the shielding component 5 and the drive mechanism 4. When the application requires frequent opening and closing of medical waste, the shielding component 5 can be manually opened and closed by pulling the top handle 16 to open the cover 13. Alternatively, when sufficient sealing is required or frequent opening is not necessary, the drive mechanism 4 can be used to control the movement of the shielding component 5, preventing manual operation errors that could cause the cover 13 to remain open for an extended period. In both states, when medical waste solution is present inside, the internal slag removal mechanism 6 can remove the residue generated after drying.

[0027] In this embodiment, the drive mechanism 4 includes a motor 23, a drive shaft 24, and an end plate 26. The output end of the motor 23 is connected to the drive shaft 24. An annular groove 25 is formed on the surface of the drive shaft 24. A positioning hole 27 is formed on one side of the end plate 26, and the end plate 26 has a semi-circular structure. The motor 23 is screwed onto the surface of one of the end plates 26. There are two annular grooves 25. The recycling bin 1 on one side of the drive shaft 24 is in a closed state. A shielding component 5 and a slag removal mechanism 6 are connected to the top of the drive mechanism 4. By locking the shielding component 5 to the drive mechanism 4, the drive mechanism 4 can control the shielding component 5 to open or close. Alternatively, the connection between the shielding component 5 and the drive mechanism 4 can be directly released, thereby achieving manual control and providing multiple control methods. Specifically, after starting the motor 23, the drive shaft 24 can be driven to rotate, and then the shielding component 5 and the slag removal mechanism 6 on the surface can be moved by the drive shaft 24. The motor 23 is directly supported by the end plate 26 on one side, while the drive shaft 24 is directly supported by the bearing embedded in the interior of the other end plate 26.

[0028] In this embodiment, the shielding assembly 5 includes a cover plate 13, a collar 14, and a handle 16. The collar 14 is welded to one end of the cover plate 13. A column 15 is integrally formed on the top of the collar 14, and a handle 16 is installed on the top of the column 15. A connecting rod 17 is inserted between the two columns 15. The collar 14 is fitted inside the annular groove 25, and a locking hole 18 is formed on its surface. The collar 14 is fixed in place by bolts passing through the locking hole 18 and embedding it into the annular groove 25. The cover plate 13 is pressed against the opening area on the top of the recycling bin 1. The initial opening angle of the shielding assembly 5 can be directly controlled, and the opening angle can be positioned and controlled during opening. This allows for adjustment of whether the opening is normally open or normally closed based on the current usage frequency of the recycling bin 1. It also allows for adjustment of the opening size based on the volume of medical and nursing waste to be processed, thereby balancing ease of placement with minimizing the exposed area.

[0029] Specifically, by manually pulling the handle 16, the column 15 can drive the bottom collar 14 and the side telescopic sleeve 19 to move. With the collar 14, the side cover 13 can be flipped, switching between covering the top of the recycling bin 1 and being open. At the same time, by controlling the rotation of the column 15, the ball bearings 22 at both ends can be rotated along the surface of the end plate 26, so that the ball bearings 22 are embedded in different positioning holes 27. By restricting the ball bearings 22 through the positioning holes 27, the opening angle of the cover 13 can be adjusted. The spring 20 structure can accommodate the extension and retraction of the ball bearings 22, so that the ball bearings 22 can be dislodged from one of the positioning holes 27 by the change in pulling force of the handle 16.

[0030] In this embodiment, both ends of the connecting rod 17 are integrally formed with telescopic sleeves 19. A connecting post 21 is inserted inside the telescopic sleeve 19. A spring 20 is welded to one end of the connecting post 21, and a ball bearing 22 is embedded at the other end of the connecting post 21. The ball bearing 22 is used to embed into the positioning hole 27. The slag removal mechanism 6 includes a push plate 2 and a scraper 3. A conveying interlayer 7 is provided at one end of the inside of the recovery box 1. The push plate 2 is welded to the surface of the drive shaft 24, and the scraper 3 is integrally formed at the end of the push plate 2. A slag discharge port 12 is provided at the top of the conveying interlayer 7, and a slag discharge channel 8 is provided at the bottom of the conveying interlayer 7. One end of the slag discharge channel 8 is connected to the external space after opening the sealing cover. The internal structure includes an arc-shaped recycling tank 10, and with the help of a slag removal mechanism 6 and an electric heating wire 11 at the bottom, it can quickly dry the medical waste liquid adhering to the tank during the recycling process. In addition, the drive mechanism 4 can scrape and discharge the residue formed after drying, providing a two-stage recycling process and reducing internal pollution.

[0031] Specifically, the motor 23 in the drive mechanism 4 drives the push plate 2 to rotate, which pushes the medical and nursing waste collected inside, and finally pushes it outward from the side near the cover plate 13. When there is medical and nursing waste liquid inside the recycling tank 10, the electric heating wire 11 at the bottom can be activated to dry the waste liquid adhering to the surface. Then, the scraper 3 is controlled to scrape along the inside of the recycling tank 10 to collect and push the dried residue toward the slag discharge port 12. Finally, the residue is discharged in a concentrated manner along the slag discharge channel 8 at the bottom inside the conveying jacket 7.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
