Description

Medical garbage can with disinfectant spraying function Technical Field The invention relates to the field of medical garbage cans, in particular to a medical garbage can with a disinfectant spraying function. Background Many medical wastes are provided with germs, and when the medical wastes are put into the garbage can, the medical wastes are preferably sprayed with disinfectant for disinfection so as to prevent the subsequent bacterial breeding and environmental pollution. For example, in the treatment of norovirus diarrhea and clostridium difficile diarrhea, it is clearly required that a certain concentration of chlorine-containing disinfectant is sprayed when articles such as diaper used by patients are treated. The common medical garbage can has no function of spraying disinfectant, and when the medical garbage is thrown, a disinfectant spraying device can be carried, and the disinfectant is sprayed by the carried disinfectant spraying device after the medical garbage is thrown. But this mode is not very convenient, and if medical waste bin has the automatic disinfectant function of spraying after the rubbish drops into, it is certainly more convenient. Through searching, some patents disclose medical waste cans with a disinfectant spraying function. The China patent with the application number 201810801959.3 discloses an environment-friendly garbage can with a disinfection function for hospitals, and a disinfection liquid storage is arranged on the garbage can, so that disinfection liquid can be sprayed out to disinfect garbage in a manual pressing mode, but the automation degree is still low. The Chinese patent with the application number 202020793952.4 discloses a self-disinfection type dustbin, which comprises a dustbin body, a dustbin cover and a disinfection device, wherein the dustbin cover is rotationally connected with one side of the dustbin body, so that the dustbin cover can be opened and closed with the dustbin body around the connection part, the disinfection device is in pressing suction type, the disinfection device comprises a spraying opening and a pressing plate, the pressing plate is rotationally connected with the dustbin body and the dustbin cover respectively, and when the dustbin cover is opened, the pressing plate enables the spraying opening of the disinfection device to spray disinfectant towards the inside of the dustbin body. The dustbin is opened, and meanwhile, disinfectant is sprayed out to disinfect the inside of the dustbin, so that the risk of infection of the dustbin to personnel is reduced. The dustbin can automatically spray the disinfectant when the dustbin cover is opened, and the spraying time is questionable although the disinfectant is automatically sprayed. The disinfectant needs a certain action time for disinfection, and when the barrel cover is opened, the disinfectant is sprayed, and the disinfectant can not kill germs immediately, so that the risk of germ overflow is still larger. And the newly input garbage is not disinfected, and germs can grow in the garbage can. Disclosure of Invention The invention aims to solve the technical problem of providing the medical dustbin with the function of spraying the disinfectant, which can automatically spray the disinfectant for disinfection after throwing the garbage. The medical garbage can with the function of spraying disinfectant comprises a garbage can body, a garbage can shell, a garbage can cover and a can cover driving structure, wherein the garbage can body is placed in the garbage can shell, the garbage can cover is covered on the garbage can shell, the can cover driving structure comprises a pedal and a push rod, the pedal can drive the push rod to jack up the garbage can cover, and the medical garbage can also comprises a disinfectant bottle, a spraying structure, a spraying driving structure, a piston rod positioner, a sprayer and a disinfectant pipeline; The disinfectant bottle is connected with the garbage can shell, the spraying structure is arranged in the up-down direction and comprises a spraying cylinder, a piston and a piston rod, the piston is positioned in the spraying cylinder and matched with the spraying cylinder, the piston rod is connected with the piston, and the piston rod is provided with a first flange, a second flange and a third flange which are sequentially arranged at intervals from bottom to top; the sterilizing liquid pipeline comprises a suction pipe and a discharge pipe, the suction pipe and the discharge pipe are both connected with the spraying cylinder, the suction pipe is inserted into the sterilizing liquid bottle, the discharge pipe is connected with the sprayer, a suction one-way valve capable of being opened unidirectionally towards the spraying cylinder is arranged on the suction pipe, and a discharge one-way valve capable of being opened unidirectionally towards the sprayer is arranged on the discharge pipe; the injection driving structure comprises a spring top p
