The bristles of the hard bristle brush are harder and it is easier to remove surface stains and debris. When the waste liquid is poured into the chamber 12 When the waste liquid is filtered through the filter 26, during use, due to the continuous introduction of waste liquid, the filter 26 will filter larger solid particles and leave them on the surface of the filter 26.

[0028] Example 2

[0029] Reference Figures 1 to 4 , which is the second embodiment of the utility model, which is different from the first embodiment in that: the inner wall of the accommodating part 1 is provided with a heating component 28; the heating components 28 are distributed in a linear array around the inner wall of the chamber 12, and the heating components 28 are made of oxygen-free copper material, which has excellent thermal conductivity and good processability, does not react with the etching waste liquid during heating, and decomposes some harmful gases during heating; the opening and closing component 3 is used to control the fluid switch of the etching waste liquid; the disinfection plate is used to disinfect the harmful gases generated by the waste liquid discharge. The thick wall of the sealing ring 22 is provided with a slot 221 and a plug sheath 222, the plug sheath 222 is cylindrical at one end close to the sealing ring 22, and is conical at one end close to the slot 221; the plug sheath 222 can be plugged into the slot 221, and is sleeved on the output side of the motor 21.
