After the door body 13 is closed and sealed, the infusion solenoid valve switch (not shown) on the infusion main pipe 6 and the three-way solenoid valve 7 on the branch pipe 71 are started in turn through the control panel 12 (specifically the controller 120). After the infusion solenoid valve switch and the three-way solenoid valve 7 are turned on, the disinfectant is quickly pressed into the upper disinfection cavity 2 through the infusion main pipe 6, the three-way solenoid valve 7, the branch pipe 71 and the nozzle 70, and then the drive motor 11 is started to rotate, so that the disinfectant on the clamp 33 The clamped medical instruments are flushed and disinfected by the disinfectant during the circular rotation. When the disinfectant can be used for disinfection within the specified time, the electromagnetic valve switch on the start-up infusion main pipe 6 is closed to stop the delivery of the disinfectant. At this time, the controller 120 turns on the discharge electromagnetic valve switch (not shown) on the discharge pipe 10 to discharge the disinfection waste liquid. At this time, the water supply electromagnetic valve switch (not shown) of the water supply main pipe 5 is turned on by the controller 120, so that the cleaning liquid (pure water or negative ion water) is quickly pressed into the upper disinfection cavity 2 through the water supply main pipe 6, the three-way electromagnetic valve 7, the branch pipe 71 and the nozzle 70, and the medical instruments clamped by the clamp 33 are sprayed and rinsed clean by the cleaning liquid during the circular rotation.

An isolation grid frame 20 is arranged at the transition between the upper disinfection cavity 2 and the lower liquid storage cavity 4 to communicate with each other. The isolation grid frame 20 is used to bear the fall of heavy objects. The isolation grid frame 20 can prevent and block the sterilized medical instruments from falling into the bottom of the lower liquid storage cavity 4. A filter plate is arranged between the lower liquid storage cavity 4 and the isolation grid frame 20; as shown in FIG3, the filter plate includes an upper filter plate 40 and a lower filter plate 41 which are arranged in an up-and-down manner. The first end of the upper filter plate 40 is connected to the side wall of the lower liquid storage cavity 4 below the first end of the isolation grid frame 20. The second end of the upper filter plate 40 is connected to the side wall of the lower liquid storage cavity 4 below the second end of the isolation grid 20 on the opposite side at an angle downward, and is butted against the first end of the lower filter plate 41. The second end of the lower filter plate 41 is connected to the side wall of the lower liquid storage cavity 4 below the first end of the isolation grid 20 at an angle downward.

When the disinfectant or cleaning liquid drips from the upper disinfection cavity 2 into the lower liquid storage cavity 4, and then flows and is filtered on the upper filter plate 40, the solid impurities in the liquid are left on the upper filter plate 40. As the liquid continues to flow downward, the solid impurities on the upper filter plate 40 are washed to the second end (the rightmost end) of the upper filter plate 40, and the solid impurities are washed into the debris collection basket 42. The remaining liquid is filtered through the collection basket 42 or the upper filter plate 40 and then enters the lower filter plate 41 for re-filtration. The final filtered liquid is discharged from the drain pipe 10. A drain solenoid valve switch (not shown) is provided on the drain pipe 10. The solenoid valve switch is electrically connected to the controller 120. The controller 120 is a single-chip microcomputer controller or a PLC controller. The controller 120 opens the electromagnetic valve switch on the lower drain pipe 10 to discharge the outlet cleaning liquid or water of the liquid storage cavity 4, and then the controller 120 opens the heater 9 to heat the medical device, and the excess water is extracted from the exhaust hole 90, and the temperature and humidity sensor 34 and the ultraviolet disinfection lamp 80 are started at the same time, so that the medical device is disinfected by ultraviolet light under a certain temperature and humidity. When the specified humidity or humidity is reached, the controller 120 stops outputting the above control signal, thereby completing the disinfection and sterilization operation of the medical device. After the disinfection is completed, the door can be opened at any time to take out the disinfected medical device. The present invention is provided with disinfectant spraying (of course, water washing can be performed before disinfection spraying), flushing after disinfection, heating, drying, dehumidification, ultraviolet disinfection and discharge of waste liquid, etc., so that the medical device is fully disinfected by liquid, flushed, heated, dried, dehumidified, disinfected and sterilized, and the medical device is safely stored without transferring the medical device, thereby making the disinfection and sterilization operation of the medical device more comprehensive. It is not easy to cause scratches to the cleaner during the cleaning process, and after disinfection, it is very easy to use without causing scratches to the cleaner.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
