[0022] The filtering mechanism 2 includes a filtering housing 21. On the inner surface of one side of the filtering housing 21, a filter screen 22 is fixedly connected. The filter screen 22 can filter debris in water. On the outer surface of one side of the filtering housing 21, two movable blocks 211 are fixedly connected. On the inner surface of one side of the pressure water pipe 13, two movable grooves 131 adapted to the movable blocks 211 are provided. On the outer surface of one side of the pressure water pipe 13, a fixed ring 23 is fixedly connected. On the inner surface of one side of the filtering housing 21, an extension plate 212 is fixedly connected. On the outer surface of one side of the extension plate 212, a connecting plate 24 is fixedly connected. On the outer surface of one side of the fixed ring 23, a through hole 231 adapted to the connecting plate 24 is provided.

[0023] On the outer surface of one side of the fixed ring 23, two fixing plates 25 are fixedly connected. On the outer surface of one side of each of the two fixing plates 25, a sliding groove 251 is provided. Inside each of the two sliding grooves 251, a sliding block 252 is slidably connected. Between the outer surfaces of one side of the two sliding blocks 252, a movable plate 26 is fixedly connected. On the top of the movable plate 26, a handle 261 is fixedly connected. The handle 261 facilitates the staff to drag the movable plate 26. On the bottom of the movable plate 26, a limiting rod 262 is fixedly connected.

When the filter housing 21 is sent into the pressure water pipe 13, one end of the connecting plate 24 will pass through the opening 231 of the fixing ring 23, and then the staff can drag the movable plate 26 through the handle 261 so that the limiting rod 262 at the bottom of the movable plate 26 can be inserted into the limiting hole 241 of the connecting plate 24, thereby fixing the position of the filter housing 21 in the pressure water pipe 13. In order to filter the water entering the pressure water pipe 13 and prevent debris from entering the subsequent pipes and causing blockage, which would affect the normal use of the foam liquid storage tank, the staff can drag the movable plate 26 by the handle 261 during use, so that the movable plate 26 can move with the limiting rod 262, and pull the limiting rod 262 out of the limiting hole 241 of the connecting plate 24, thereby not affecting the movement of the connecting plate 24. The staff can then pull the connecting plate 24, so that the connecting plate 24 can be pulled out of the pressure water pipe 13 with the filter housing 21, thereby facilitating the staff to inspect and maintain the filter housing 21 and the filter screen 22 in the filter housing 21.
