In this embodiment, the piston rod 8 has various shapes, and may be formed by splicing a plurality of U-shaped frames, and sealing mechanisms are disposed among the piston rod, the piston, and the negative pressure tube.

The utility model discloses a concrete use and efficiency:

when the garbage bin is used, a medical worker steps on the pedal 5 firstly, the front end of the pedal 5 descends and the rear end of the pedal 5 ascends, the rear end of the pedal 5 props against the ejector rod 4, the upper end of the ejector rod 4 props against the end cover 3 and ascends, so that the end cover 3 is opened, infectious medical wastes are put into the feed inlet at the moment and then fall into a cavity formed by the two partition plates 13 and the side walls of the circular cavity, then the partition plates 13 rotate so as to drive the medical wastes to move until the infectious medical wastes fall into the bin body 1 from an opening at the lower end of the circular cavity, compared with a traditional foot-stepping garbage bin, in the process of putting the medical wastes, the interior of the bin body 1 is separated from the outside by the partition plates, so that the interior of the bin body 1 is relatively sealed, the diffusion of peculiar smell and bacteria is reduced, the probability of infection caused by the medical wastes in the bin body 1 is reduced, the two rotating shafts 2 rotate along with the opening of the end cover 3 so as to drive the two eccentric wheels 6 to rotate, the eccentric wheels 6 drive the connecting rod 7 to deflect so as to drive the piston rod 8 to move backwards, the piston moves backwards in the negative pressure tank, thereby the disinfectant in the negative pressure pipe 9 is squeezed into the spray pipe 11 and then is sprayed out from the atomizing nozzle at the tail end of the spray pipe 11, bacteria are further killed, peculiar smell diffusion is prevented, after the device is used for many times, all the partition plates 13 are kept still in the box body 1 for a period of time, the surface layers of the partition plates 13 are all contaminated by peculiar smell and bacteria in the box body 1, the sprayed disinfectant can sterilize the surface layers of the partition plates 13 at the moment, the bacteria contaminated on the partition plates 13 and the peculiar smell diffusion outside are reduced, and the atomizing nozzle atomizes the disinfectant, thereby the spraying area of the disinfectant is enlarged, the disinfecting effect is better, when the end cover 3 is closed, the two rotating shafts 2 are reset to drive the eccentric shaft to reset, thereby the connecting rod 7 drives the piston rod 8 to reset, the piston moves forwards to suck the disinfectant in the storage tank 12 into the negative pressure pipe 9, the device is convenient to use next time, when the device is just installed, the end cover 3 is closed, and no disinfectant water exists in the negative pressure pipe 9, so the device is required to be used for the first time, namely, the medical waste is not thrown in and the pedal 5 is stepped on, and then the device can be normally used, the box body 1 and the storage tank 12 are both made of transparent materials, after the fact that the inside of the box body 1 is fully thrown and the disinfectant water in the storage tank 12 is used up is sensed, even if the device is processed, the medical waste is transferred by opening a door, and the disinfectant water is filled in the device through the feeding pipe;

and when the ejector rod 4 rises, the side wall of the limiting rod 18 pushes against the round rod 19 to rise, and drives the lower clamping plate 15 to rise, the lower clamping plate 15 pushes against the sliding block through the driving plate to move towards the direction of the rotating shaft 14 of the principle separation plate 13, so that the upper clamping plate 15 is driven to fall through the driven rod 17, after the end cover 3 is completely opened, the rotating shafts 14 of the two clamping plates 15 and the main separation plate 13 are driven to brake the separation plate 13, after the pedal 5 is released, the two clamping plates 15 reset under the action of the tension spring, and the separation plate 13 is not limited, so that when medical waste is put in, the medical waste is prevented from being in direct contact with the side wall of the separation plate 13, the separation plate 13 directly rotates, for a larger piece of medical waste, the upper part is possibly clamped, and the existence of the braking mechanism, so that when the end cover 3 is opened, the separation plate 13 is braked until the medical waste falls between the two separation plates 13, medical waste is released by medical personnel, and the pedal 5 can move and fall into the box 1, thereby avoiding the problem that the separation plate 13 rotates due to being clamped.

If the partition plate 13 is opposite to the feeding hole, the pedal 5 can be slightly loosened, the two clamping plates 15 are not used for tightly clamping the rotating shaft 14 of the partition plate 13, the partition plate 13 is slightly moved, the pedal 5 is treaded down again after the movement, and the pedal 5 is loosened after medical waste is put in, so that the end cover 3 is closed.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
