After the sterilization, the control valve 131 is opened, and the sterilized cleaning wastewater is discharged directly into the sewage through the drain pipe 13. The whole process is simple to operate and convenient to use, can effectively disinfect the cleaning wastewater, avoids polluting the environment and reduces the propagation risk of bacteria and viruses.

Referring to fig. 6, 7 and 8, in some embodiments of the present application, the medical waste disposal device 1 further comprises an agitation mechanism 14; the stirring mechanism 14 comprises a stirring motor 141, a stirring blade 142, a scraper 143, a mounting shaft 144, a ratchet wheel 145, a pawl 146 and an elastic member 147; the stirring motor 141 is arranged at the upper end of the tank body 11, and an output shaft of the stirring motor 141 penetrates into the tank body 11 and then is connected with the stirring blade 142; an accommodating cavity 1421 is formed at the upper end of the stirring blade 142, the ratchet wheel 145 is coaxially and rotatably arranged in the accommodating cavity 1421, and the pawl 146 is rotatably arranged in the accommodating cavity 1421; the elastic member 147 is disposed in the accommodating cavity 1421, and the elastic member 147 is used to force the pawl 146 to engage with the ratchet wheel 145; the upper end of the mounting shaft 144 is coaxially disposed on the ratchet wheel 145, and the lower end of the mounting shaft 144 is connected to the scraper 143. Referring to fig. 14 and 20, after the stirring motor 141 is started, the output shaft of the stirring motor 141 drives the stirring blade 142 to rotate, so that the washing wastewater is continuously stirred by the stirring blade 142 during the boiling process, thereby preventing the impurities in the washing wastewater from precipitating. As shown in fig. 21, when the stirring motor 141 drives the stirring blade 142 to rotate counterclockwise, the pawl 146 does not generate torque to the ratchet wheel 145, and at this time, the ratchet wheel 145 does not rotate, that is, the mounting shaft 144 and the scraper 143 do not rotate; when the stirring motor 141 drives the stirring blade 142 to rotate clockwise, the pawl 146 generates torque to the ratchet wheel 145, the ratchet wheel 145 rotates along with the stirring blade 142, and at this time, the scraper 143 scrapes the inner wall of the tank 11, so as to clean the sediment attached to the inner wall of the tank 11 in time.

As shown in fig. 14, under the action of the return spring 149, the mounting shaft 144 is forced to slide upwards to separate the scraper 143 from the inner bottom surface of the tank 11, when the inner bottom surface of the tank 11 needs to be scraped, the electromagnet 148 is gradually activated to gradually increase the magnetic force of the electromagnet 148, so that the mounting shaft 144 is forced to slide downwards slowly, so that the scraper 143 gradually contacts with the sediment to gradually scrape off the sediment attached to the inner bottom surface of the tank 11, and the instantaneous load of the stirring motor 141 and the abrasion caused by the scraper 143 can be reduced; otherwise, if the scraper 143 directly contacts with the inner bottom surface of the tank 11, the resistance of the scraper 143 to the sediment is the largest at the moment of starting the scraper 143, which not only increases the instantaneous load of the stirring power, but also increases the wear of the scraper 143, and even may cause the scraper 143 to be scrapped when it is serious. In addition, when the two ends of the scraper 143 along the radial direction of the mounting shaft 144 are respectively contacted with the inner side wall of the tank 11, the inner side wall of the tank 11 can be scraped and washed at the same time; under the action of the electromagnet 148 and the return spring 149, the scraper 143 can be driven by the mounting shaft 144 to slide up and down, so that the scraping area of the scraper 143 can be increased when the size of the scraper 143 is the same, and the size of the scraper 143 can be decreased when the size of the scraper 143 is the same. It should be noted that the present application does not limit the sliding installation manner between the mounting shaft 144 and the ratchet wheel 145, for example, as shown in fig. 21, a sliding groove 1451 may be provided on the axis of the ratchet wheel 145, a sliding block 1442 may be provided on the mounting shaft 144, and the sliding engagement between the sliding block 1442 and the sliding groove 1451 may realize the sliding connection between the mounting shaft 144 and the ratchet wheel 145, and may avoid the relative rotation between the mounting shaft 144 and the ratchet wheel 145. In addition, the way that the electromagnet 148 attracts the mounting shaft 144 is the prior art, for example, a limiting block 1441 may be disposed at the upper end of the mounting shaft 144, the limiting block 1441 itself is a magnet, or the limiting block 1441 is filled with a magnet; meanwhile, the limit block 1441 may also limit the return spring 149.

Referring to fig. 6 and 7, the stirring blade 142 is provided with a cylindrical shaft hole 1422 along the vertical direction, the mounting shaft 144 is slidably connected in the shaft hole 1422, the fixing effect on the mounting shaft 144 can be enhanced through the shaft hole 1422, and the stability of the mounting shaft 144 in the rotating process can be improved.
