The crushing mechanism 5 is used to crush medical waste and transport the crushed medical waste to the feeding area 3A, the conveying mechanism 4 is used to pull the medical waste in the feeding area 3A through the irradiation area 3B and the spraying area 3C in sequence and output it outward from the discharge area 3D, the No. 1 disinfection mechanism 6 is used to emit ultraviolet rays to the medical waste in the irradiation area 3B, and the No. 2 disinfection mechanism 7 is used to spray disinfectant to the medical waste in the spraying area 3C. The crushing mechanism 5 is a prior art in the mechanical field and will not be described in detail here.

[0031] Furthermore, the conveying mechanism 4 includes a rotating shaft 41 and a rotating ring 43. The rotating shaft 41 is rotatably installed at the center of the lower supporting plate 3. The surface of the rotating shaft 41 is fixedly connected to a sleeve 42. The rotating ring 43 has a circular ring structure. The surface of the sleeve 42 and the inner wall of the rotating ring 43 are fixedly connected by a connecting plate 44. There are multiple connecting plates 44, and the multiple connecting plates 44 are distributed in an array in the circumferential direction of the rotating shaft 41. A flip assembly 45 is provided between two adjacent connecting plates 44. A servo motor 46 is fixedly installed at the bottom of the lower supporting plate 3. The output end of the servo motor 46 is fixedly connected to the bottom end of the rotating shaft 41. The servo motor 46 is used to control the overall intermittent rotational movement of the conveying mechanism 4.

[0032] The lower supporting plate 3 is a circular plate structure. The outer surface of the lower supporting plate 3 is fixedly connected to a support frame 31. The top of the support frame 31 is fixedly connected to a gear ring 32. A through-hole 33 is opened in the discharge area 3D. The bottom of the through-hole 33 is fixedly connected to a discharge nozzle 35. A weighing module 34 is provided in the injection area 3C. The top of the upper supporting plate 2 is fixedly connected to a feed nozzle 21. The feed nozzle 21 is located directly above the feed area 3A. The feed nozzle 21 is fixedly connected to the output end of the crushing mechanism 5. A collecting cylinder 8 is provided at the bottom of the discharge nozzle 35.

[0033] The flip assembly 45 includes a fixed rod 451, which is fixedly connected to the rotating ring 43, and one end of the fixed rod 451 passes through the rotating ring 43 and extends to the outside of the rotating ring 43. A transmission rod 452 is rotatably installed inside the fixed rod 451, and one end of the transmission rod 452 passes through one end of the fixed rod 451 and extends outward. One end of the transmission rod 452 is fixedly connected to a bevel gear 1 457, and the bevel gear 1 457 is meshed with the ring gear 32. A transmission cavity is opened inside the fixed rod 451, and the transmission cavity is provided with multiple A rotating rod 453 is rotatably installed in the transmission cavity, and two rotating rods 453 are symmetrically arranged in each transmission cavity. The rotating rod 453 passes through the inner wall of the transmission cavity and extends outward. A blade 454 is fixedly connected to the surface of the rotating rod 453. One end of the rotating rod 453 is fixedly connected to a bevel gear three 456. The bevel gear three 456 is located in the transmission cavity. A bevel gear two 455 is also provided in the transmission cavity. The bevel gear two 455 is fixedly installed on the surface of the transmission rod 452, and the bevel gear two 455 is meshed with the bevel gear three 456.

[0034] During use, the servo motor 46 drives the rotating shaft 41 to rotate around its own axis. The rotating shaft 41 rotates and drives the entire conveying mechanism 4 to rotate synchronously and intermittently around the axis of the rotating shaft 41. The staff puts medical waste into the input end of the pulverizing mechanism 5, and the pulverizing mechanism 5 pulverizes the medical waste. After that, the medical waste enters the feeding area 3A through the feeding nozzle 21 and is located between two adjacent connecting plates 44. When the conveying mechanism 4 rotates, the medical waste is pushed by the connecting plates 44 and moves synchronously therewith, so that the medical waste passes through the irradiation area 3B and the injection area 3C in sequence.

[0035] During the rotation of the conveying mechanism 4, since the bevel gear 1 457 and the ring gear 32 are meshed with each other, the bevel gear 1 457 rotates synchronously around its own axis. The bevel gear 1 457 rotates and drives the transmission rod 452 to rotate synchronously around its own axis. The transmission rod 452 rotates and drives the rotating rod 453 to rotate synchronously around its own axis through the bevel gear 2 455 and the bevel gear 3 456. The rotating rod 453 rotates and drives the blades 454 to rotate synchronously around the axis of the rotating rod 453. The blades 454 stir the medical waste.

[0036] After leaving the injection area 3C, the medical waste enters the discharge area 3D. Finally, under the action of its own gravity, the medical waste passes through the penetration port 33 and the discharge nozzle 35 and enters the collection tube 8.

[0037] In summary, the conveying mechanism 4 can pull the medical waste through the irradiation area 3B and the spraying area 3C in sequence. The No. 1 disinfection mechanism 6 and the No. 2 disinfection mechanism 7 cooperate with each other to effectively improve the antibacterial disinfection effect. In addition, the staff can put in medical waste at any time without waiting for the antibacterial disinfection of one batch of medical waste to be completed before putting in the next batch, which improves the operating efficiency. In addition, when the medical waste passes through the irradiation area 3B, the blades 454 stir the medical waste by flipping, so that the medical waste can receive ultraviolet rays more fully and evenly. When the medical waste passes through the spraying area 3C, the blades 454 stir the medical waste by flipping, so that the medical waste can receive the disinfectant more fully and evenly.

[0038] Furthermore, the first disinfection mechanism 6 includes an extension shell 61, which is fixedly mounted on the top of the upper supporting plate 2. An ultraviolet lamp 62 is provided in the extension shell 61, and the ultraviolet lamp 62 is located directly above the irradiation area 3B.

[0039] The second disinfection mechanism 7 includes a liquid storage tank 71 for storing disinfectant, a metering pump 72 and an atomizing nozzle 73. The liquid storage tank 71 and the atomizing nozzle 73 are both fixedly installed on the top of the upper supporting plate 2. The input end of the metering pump 72 is fixedly connected to the liquid storage tank 71 through a guide pipe 74, and the output end of the metering pump 72 is fixedly connected to the input end of the atomizing nozzle 73. The atomizing nozzle 73 is located directly above the spraying area 3C.

[0040] During use, when medical waste passes through the irradiation area 3B, the ultraviolet light emitted by the ultraviolet lamp 62 irradiates the medical waste;

[0041] When medical waste passes through the spraying area 3C, the weighing module 34 senses the weight of the medical waste and controls the metering pump 72 to open through the single-chip microcomputer. Under the action of the metering pump 72, the disinfectant in the liquid storage tank 71 is sprayed onto the medical waste through the atomizing nozzle 73. In addition, the weighing module 34 determines the amount of medical waste in the spraying area 3C based on the weight of the medical waste and controls the metering pump 72 to output different amounts of disinfectant according to the amount of medical waste. (If the weighing module 34 does not sense the weight, it means that no medical waste has entered the spraying area 3C, and the metering pump 72 remains closed.

[0042] In summary, the ultraviolet rays emitted by the ultraviolet lamp 62 first destroy the DNA structure of the microorganisms and weaken their activity, and then the disinfectant is sprayed through the atomizing nozzle 73, making it easier for the disinfectant to penetrate and kill residual pathogens. In addition, through the induction of the weighing module 34 and the precise control of the metering pump 72, the medical waste receives the most appropriate amount of disinfectant, effectively avoiding the influence of too much or too little disinfectant on the antibacterial disinfection effect.

[0043] Working principle of the present invention:

[0044] The servo motor 46 drives the rotating shaft 41 to rotate around its own axis. The rotating shaft 41 rotates and drives the entire conveying mechanism 4 to rotate synchronously and intermittently around the axis of the rotating shaft 41 .

[0045] The staff puts medical waste into the pulverizing mechanism 5 through the input end, and the pulverizing mechanism 5 pulverizes the medical waste. Then, the medical waste enters the feeding area 3A through the feeding nozzle 21 and is located between two adjacent connecting plates 44. When the conveying mechanism 4 rotates, the medical waste moves synchronously with it under the push of the connecting plates 44, so that the medical waste passes through the irradiation area 3B and the injection area 3C in sequence.

[0046] During the rotation of the conveying mechanism 4, since the bevel gear 1 457 and the ring gear 32 are engaged with each other, the bevel gear 1 457 rotates synchronously around its own axis, the bevel gear 1 457 rotates and drives the transmission rod 452 to rotate synchronously around its own axis, the transmission rod 452 rotates and drives the rotating rod 453 to rotate synchronously around its own axis through the bevel gear 2 455 and the bevel gear 3 456, the rotating rod 453 rotates and drives the blade 454 to rotate synchronously around the axis of the rotating rod 453.

[0047] When the medical waste passes through the irradiation area 3B, the ultraviolet light emitted by the ultraviolet lamp 62 irradiates the medical waste, and the blades 454 stir the medical waste by turning over, so that the medical waste is more fully and evenly exposed to the ultraviolet light.

[0048] When the medical waste passes through the spraying area 3C, the weighing module 34 senses the weight of the medical waste and controls the metering pump 72 to open through the single-chip microcomputer. Under the action of the metering pump 72, the disinfectant in the liquid storage tank 71 is sprayed to the medical waste by the atomizing nozzle 73, and the blades 454 stir the medical waste by flipping, so that the medical waste can receive the disinfectant more fully and evenly. In addition, the weighing module 34 determines the amount of medical waste in the spraying area 3C based on the weight of the medical waste, and controls the metering pump 72 to output different amounts of disinfectant according to the amount of medical waste (if the weighing module 34 does not sense the weight, it means that no medical waste has entered the spraying area 3C, and the metering pump 72 remains closed).

[0049] After leaving the injection area 3C, the medical waste enters the discharge area 3D. Finally, under the action of its own gravity, the medical waste passes through the penetration port 33 and the discharge nozzle 35 and enters the collection tube 8.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
