[0026] The trash can 1 includes a trash can body 11 and a flip-top cover 12 that can be flipped and installed on the upper part of the trash can body 11. Specifically, a damper can be installed between the flip-top cover 12 and the trash can body 11 to prevent the flip-top cover 12 from flipping and affecting the dumping of medical waste when it is dumped. The installation of a damper in the trash can 1 is a conventional technology in the field of trash can 1. The installation of the damper and its specific working principle will not be described in detail here.

[0027] The processing unit 3 includes a processing component 5 for crushing and disinfecting medical waste, a protective shell 6 covering the outer perimeter of the processing component 5, a feeding port 7 located on the top of the protective shell 6 opposite to the processing component 5, and a bin-turning machine 8 located on one side of the protective shell 6 to lift and turn the waste bin 1. The waste bin 1 is lifted upwards and turned downwards by the bin-turning machine 8, allowing the medical waste inside to enter the processing component 5 through the feeding port 7. Specifically, the protective shell 6 can be used in conjunction with negative pressure equipment and a multi-stage exhaust gas purification system to isolate toxic gases and pathogens during the processing, eliminating the risk of infection and health hazards to workers. The bin-turning machine 8 is a commonly used device in the lifting and turning of waste bin 1, and its specific structure and working principle will not be further described here.

[0028] Processing assembly 5 includes a processing frame 51 disposed in a protective shell 6, a processing barrel 52 disposed on the processing frame 51, a processing chamber 53 disposed in the processing barrel 52 opposite to the feed port 7, a crushing component 54 rotatably disposed in the processing chamber 53, a sealing cover 55 disposed on the upper end of the processing barrel 52 to seal the upper end of the processing chamber 53, a rotating component 56 disposed on the processing frame 51 and connected to and driving the crushing component 54 to rotate, a wear-resistant liner 57 disposed on the inner wall of the processing chamber 53 opposite to the crushing component 54, and a discharge valve disposed on the outer side of the lower end of the processing barrel 52. The feed inlet 58 and the sealing plate 59 for sealing the discharge port 58 are provided. When the tipper 8 operates and drives the garbage bin 1 to rise, the sealing cover 55 flips upward to open the upper end of the processing chamber 53, allowing the medical waste inside the garbage bin 1 to enter the processing chamber 53. Specifically, a tipping component 50 can be set on the side of the processing bin 52 so that the sealing cover 55 and the sealing plate 58 can automatically flip to open the upper end of the processing chamber 53 or the discharge port 58. The tipping component 50 can adopt a cylinder and linkage mechanism, and the linkage mechanism is connected to the sealing cover 55 or the sealing plate 59.

[0029] The processing tank 52 includes a processing tank body 521 supported on the processing frame 51 and a support edge 522 disposed on the upper end of the processing tank body 521, wherein the support edge 522 is supported on the edge of the feed port 7, and the sealing cover 55 is flipped and disposed on one side of the upper end of the processing tank body 521 to open or seal the processing chamber 53.

[0030] The crushing component 54 includes a crushing frame 541 rotatably disposed in the processing chamber 53, a rotating main shaft 542 rotatably disposed at the bottom of the processing bucket 52 and connected to the crushing frame 541, and crushing blades 543 disposed on the crushing frame 541. The lower end of the rotating main shaft 542 extends downward to the outside of the processing bucket 52, and a rotating component 56 connects to and drives the rotating main shaft 542 to rotate. Specifically, the crushing frame 541 includes a main crushing frame 544 connected to the upper end of the rotating main shaft 542 and two crushing sub-frames 545 disposed opposite to each other on both sides of the main crushing frame 544. The crushing blades 543 include a first crushing blade 546 disposed on the main crushing frame 544 and two second crushing blades 547 disposed on the two crushing sub-frames 545 respectively. Further, the second crushing blades 547 are arranged around the outer side of the crushing sub-frames 545. Through the cooperation of the first crushing blades 546 and the second crushing blades 547, the medical waste entering the processing chamber 53 is crushed.

[0031] The rotating component 56 includes a rotating motor 561 mounted on the processing frame 51 on one side of the processing barrel 52, a first rotating gear 562 connected to the output shaft of the rotating motor 561, a second rotating gear 563 mounted on the lower end of the rotating main shaft 542 opposite to the first rotating gear 562, a transmission toothed belt 564 mounted between the first rotating gear 562 and the second rotating gear 563, a guide sleeve 565 extending downward from the bottom of the processing barrel 52, and multiple guide bearings 566 mounted in the guide sleeve 565. The rotating main shaft 542 extends downward through the multiple guide bearings 566 in the guide sleeve 565 and is connected to the second rotating gear 563.

[0032] The wear-resistant liner 57 includes a first liner section 571, a second liner section 572, and a third liner section 573 arranged sequentially from bottom to top. The thickness of the first liner section 571 is greater than the thickness of the second liner section 572, and the thickness of the third liner section 573 is less than the thickness of the second liner section 572. The first liner section 571 is opposite to the crushing frame 541 and the crushing blade 543. By setting the wear-resistant liner 57 on the inner wall of the processing chamber 53, the impact force on the inner wall of the processing chamber 53 during the rotation and crushing of medical waste is absorbed. The structure of the wear-resistant liner 57 is further defined. Since the first liner section 571, which is opposite to the crushing frame 541 and the crushing blade 543, will bear a large impact force, its thickness is limited to the maximum to extend its wear resistance time. Together with the second liner section 572 and the third liner section 573, the service life of the wear-resistant liner 57 is effectively extended, saving processing costs.

[0033] The handling robot 4 includes a walking unit 41, a lifting seat 42 that can move up and down in the walking unit 41, and a lifting component that drives the lifting seat 42 to move up and down in the walking unit 41. The lifting seat 42 can move upward and support the bottom of the trash can 1 to move the trash can 1 in conjunction with the walking unit 41. Specifically, the handling robot 4 with the lifting seat 42 is a common robot in the field of handling robots and is existing technology. Its specific structure and working principle will not be described in detail here.

[0034] The specific steps involved in disposing of medical waste are as follows:

[0035] Step 1: The staff moves the trash can 1, which is full of medical waste, to the temporary storage area 2 and flips the lid 12 upward to open the trash can body 11.

[0036] Step 2: The transport robot 4 moves along the preset trajectory to the bottom of the trash can 11, and then controls the lifting seat 42 to move upward to lift the trash can 11. The walking unit 41 continues to work to move the trash can 1 to the tipping machine 8, and then controls the lifting seat 42 to move downward to reset so that the trash can 1 is connected to the tipping machine 8.

[0037] Step 3: The sealing cover 55 is flipped upward to open the upper end of the processing chamber 53. The tipping machine 8 works to lift the trash can 1 upward and, after being lifted into place, flips the trash can 1 downward to pour the medical waste inside the trash can 1 into the processing bin 52.

[0038] Step 4: The tipper 8 moves downwards and resets the empty trash can 1. The sealing cover 55 flips downwards to seal the upper end of the processing chamber 53. The rotating part 56 controls the rotating main shaft 542 to rotate, which drives the crushing frame 541 to rotate. This causes the crushing blade 543 to crush the medical waste in the processing chamber 53. During the high-speed rotation of the crushing frame 541 and the crushing blade 543, the medical waste in contact with it will collide with each other between the crushing part 54 and the wear-resistant liner 57, generating displacement and converting mechanical energy into heat energy, which will cause the medical waste to heat up, so as to achieve the effect of crushing and disinfection.

[0039] Step 5: After the medical waste is crushed and disinfected, the sealing plate 59 opens the discharge port 58 to discharge the processed medical waste from the processing chamber 53.

[0040] This application defines the structure of the processing device, which is set in the temporary storage area 2 of the temporary waste bin 1. During processing, the transport robot 4 moves the waste bin 1, which is full of medical waste in the temporary storage area 2, to the processing unit 3. The bin tipping machine 8, together with the transport robot 4, lifts the waste bin 1 upward and flips it downward, so that the medical waste is dumped into the processing component 5, thereby realizing the automatic dumping of medical waste. The empty waste bin 1 can also be transferred to the disinfection area by the transport robot 4 for disinfection without the need for staff intervention, thus isolating the spread of toxic gases and pathogens and reducing the harm to staff during the medical waste processing.

[0041] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
