In the present invention, the filter plate is one or more layers and is arranged in an up-down tilted manner. As an embodiment of the present invention, preferably, the filter plate is two layers, which includes an upper filter plate 50 and a lower filter plate 51 arranged in an up-down tilted manner. A filter groove 52 is horizontally arranged along the side wall of the lower liquid storage cavity 21. The first end of the upper filter plate 50 is connected to the side wall of the lower liquid storage cavity 21 below the first end of the support beam 42, and the second end of the upper filter plate 50 is connected to the lower side of the second end of the support beam 42 on the opposite side and is connected to the side wall of the lower liquid storage cavity 21. The first end of the lower filter plate 51 is connected to the side wall of the lower liquid storage cavity 21 at the filter tank 52, and the bottom of the filter tank 52 is close to (or tangentially in contact with) the first end of the lower filter plate 51, and the second end of the lower filter plate 51 is tilted downward and connected to the side wall of the lower liquid storage cavity 4 below the first end of the support beam 42; that is, the right end of the upper filter plate 50 is high (the first end is high) and the left end is low (the second end is low), and the left end of the lower filter plate 51 is high (the first end is high) and the right end is low (the second end is low). When the disinfectant or cleaning liquid drips from the upper disinfection cavity 20 The liquid falls into the lower liquid storage cavity 21, then flows and is filtered on the upper filter plate 50, and the solid impurities in the liquid are left on the upper filter plate 50. As the liquid continues to flow downward, the solid impurities on the upper filter plate 50 are washed to the second end (the rightmost end) of the upper filter plate 50, and the solid impurities are washed into the filter tank 52. The remaining liquid is filtered through the filter tank 52 or the upper filter plate 50 and then enters the lower filter plate 51 for re-filtration. The last filtered liquid is discharged from the drain pipe 9. In the specific implementation, between the first end of the upper filter plate 50 and the side wall of the lower liquid storage cavity 21 and A support platform 54 fixed on the side wall of the lower liquid storage cavity 21 is also provided between the first end of the lower filter plate 51 and the side wall of the lower liquid storage cavity 21, and the support platform 54 is also inclined in the inclination direction of the filter plate, and the first end of the upper filter plate 50 and the second end of the lower filter plate 51 are respectively fixedly connected to the edges of their respective corresponding support platforms 54, and the inclined arrangement of the upper filter plate 50 and the lower filter plate 51 makes it convenient for residues to not remain on the plate surface, and the upper filter plate 50 and the lower filter plate 51 and the support platform 54 are easier to install and disassemble, and the side wall of the disinfection cavity will not be damaged during the installation operation.

As another embodiment of the present invention, the filter plate is three-layered, including an upper filter plate 50 and a lower filter plate 51 which are arranged to be inclined upward and downward and an intermediate filter plate 53 which is horizontally arranged between the upper filter plate 50 and the lower filter plate 51. A filter groove 52 is horizontally arranged along the side wall of the lower liquid storage cavity 21. The first end of the intermediate filter plate 53 is connected to the side wall of one end of the lower liquid storage cavity 21, and the second end of the intermediate filter plate 53 horizontally passes through the filter groove 52 for connection. The first end of the upper filter plate 50 is connected to the side wall of the lower liquid storage cavity 21 below the first end of the support beam 42, and the second end of the upper filter plate 50 is tilted downward and connected to the support beam 42 on the opposite side. Below the second end of the support beam 42, and connected to the notch of the filter tank 52 set on the side wall of the lower liquid storage cavity 21, the first end of the lower filter plate 51 is connected to the side wall of the lower liquid storage cavity 21 at the outer side wall of the filter tank 52, and the bottom of the filter tank 52 is close to the first end of the lower filter plate 51, and the second end of the lower filter plate 51 is tilted downward and connected to the side wall of the lower liquid storage cavity 4 below the first end of the middle filter plate 53; the middle filter plate 53 is formed by a plurality of horizontal filter plates 530 and a plurality of straight slots 531 that are continuously and evenly spaced and staggered and connected as one body, and a notch at one end of the straight slot 530 horizontally passes through the filter tank 52 for connection.

That is, the right end of the upper filter plate 50 is high (the first end is high) and the left end is low (the second end is low), the left end of the lower filter plate 51 is high (the first end is high) and the right end is low (the second end is low), and the middle filter plate 53 is horizontally arranged on the horizontal plane between the filter tank 52 and the lower filter plate 51. When the disinfectant or cleaning liquid drips from the upper disinfection cavity 20 into the lower liquid storage cavity 21, and then flows and filters on the upper filter plate 50, the solid impurities in the liquid are left on the upper filter plate 50, and as the liquid continues to flow downward, the solid impurities on the upper filter plate 50 are removed. The liquid is washed to the middle filter plate 53. Since the middle filter plate 53 is provided with a straight groove body 530, the excess residual slag can be washed into the filter tank 52 along the straight groove body 530 again. The middle filter plate 53 can adopt the existing multi-layer filter plate and the metal mesh filter plate with amorphous alloy particles in the middle. The liquid reacts with the amorphous alloy particles to adsorb or partially ionize some harmful elements in the liquid, and continues to form precipitated residues that are filtered and collected by the filter tank 52 and filtered by the lower filter plate 51.

Therefore, the liquid flows to the second end (the leftmost end) of the upper filter plate 50 and flows into the filter tank 52, flushing the solid impurities into the filter tank 52. The remaining liquid is filtered through the filter tank 52 and the middle filter plate 53, and then enters the lower filter plate 51 for re-filtration. The last filtered liquid is discharged from the drain pipe 9. In the specific implementation, there are also liquids between the first end of the upper filter plate 50 and the side wall of the lower liquid storage cavity 21, between the second end of the middle filter plate 53 and the side wall of the lower liquid storage cavity 21, and between the first end of the lower filter plate 51 and the side wall of the lower liquid storage cavity 21.

The first end of the upper filter plate 50 and the first end of the lower filter plate 51 are respectively fixedly connected to the edges of their respective corresponding support platforms 54, and the upper filter plate 50 and the lower filter plate 51 are arranged in an inclined manner so that residue does not remain on the plate surface, and the upper filter plate 50, the lower filter plate 51 and the middle filter plate 53 are easier to install, connect and disassemble with the support platform 54, so as not to damage the side wall of the disinfection cavity during the installation operation.

When it is necessary to disinfect the medical instruments, the door body 12 is opened, and the medical instruments are clamped on the clamping member 501 in turn. The rotating shaft 4 is rotated by pushing the suspension arm 5 to clamp the medical instruments on the clamping member 501 in turn. After the door body 12 is closed and sealed, the infusion solenoid valve switch (not shown) on the infusion main pipe 6 and the three-way solenoid valve 72 on the branch pipe 71 are started in turn by the controller 11 in the control box 10. After the infusion solenoid valve switch and the three-way solenoid valve 72 are turned on, the disinfectant is quickly pressed into the upper disinfection cavity 2 through the infusion main pipe 7, the three-way solenoid valve 72, the branch pipe 71 and the nozzle 70, and then the drive motor 3 is started to rotate, so that the medical instruments clamped by the clamping member 501 are flushed and disinfected by the disinfectant during the circular rotation. When the disinfectant is used within the specified time, After the disinfection with the disinfectant is completed, the electromagnetic valve switch on the start-up infusion main pipe 7 is closed to stop the delivery of the disinfectant. At this time, the controller 11 outputs a control instruction to open the discharge electromagnetic valve switch 90 on the discharge pipe 9 to discharge the disinfectant waste liquid. At this time, the controller 11 outputs a control instruction to open the water supply electromagnetic valve (not shown) of the water supply main pipe 6, 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 72, the branch pipe 71 and the nozzle 70, and the medical instrument clamped by the clamp 501 is sprayed and rinsed by the cleaning liquid during the circular rotation; the three-way electromagnetic valve 72 adopts a two-position three-way electromagnetic valve, and is a two-in-one-out three-way electromagnetic valve 72, so that the disinfection and spray cleaning can be operated in time.

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