When the first tube body 101 is connected to the second tube body 201 and the first valve 104 is opened, the first tube body 101 and the second tube body 201 form a ring. The hydrogen peroxide circulates inside the first tube body 101 and the second tube body 201, so that the hydrogen peroxide continuously passes through the reverse osmosis filter membrane 204 and the macroporous adsorption resin column 205 to continuously perform reverse osmosis filtration and impurity filtration, thereby improving the filtering effect of the hydrogen peroxide. When the first valve 104 is closed and the second valve 105 is opened, the hydrogen peroxide can be introduced into the first tube body 101 through the liquid inlet pipe 102. When the first valve 104 is closed and the third valve 106 is opened, the hydrogen peroxide is discharged through the liquid outlet pipe 103, thereby facilitating the feeding and discharging of the hydrogen peroxide.

[0024] The clamping and fixing assembly 3 includes a fixing plate 301 fixedly installed on the first tube body 101 and the second tube body 201, wherein a plug plate 302 is fixedly installed on one of the fixing plates 301, and a plug sleeve 303 is fixedly installed on the other fixing plate 301, the plug plate 302 is inserted into the plug sleeve 303, and a clamping slot 304 is symmetrically provided on the plug plate 302, and a fixing box 305 is fixedly installed on the plug sleeve 303, and a movable plate 306 is movably installed inside the fixing box 305, and a clamping rod 307 is symmetrically installed on one side of the movable plate 306, and the clamping rod 307 is clamped with the clamping slot 304, and the movable plate 306 is away from the side of the clamping rod 307 A spring 308 is symmetrically installed, one end of which is fixedly connected to the inner wall of the fixed box 305 away from the plug plate 302, and a pull rod 309 is fixedly installed on the side of the movable plate 306 away from the clamping rod 307.

When all the hydrogen peroxide is introduced, the second valve 105 is closed, and the first valve 104 is opened, and the pump body 203 is turned on.

[0027] When the filtration is finished, the first valve 104 is closed and the third valve 106 is opened, so that the hydrogen peroxide is discharged from the liquid outlet pipe 103;

[0028] When the reverse osmosis filter membrane 204 and the macroporous adsorption resin column 205 need to be replaced, the first tube body 101 and the second tube body 201 can be disassembled to replace the reverse osmosis filter membrane 204 and the macroporous adsorption resin column 205 .
