[0036] In the embodiment, the electromagnetic valve 4 is connected with the discharge pipeline of the filter unit 2 through the assembling structure 3, when the electromagnetic valve 4 is opened, the dirt in the discharge pipeline of the filter unit 2 is discharged from the electromagnetic valve 4, the time when the time delay relay 5 is energized to the electromagnetic valve 4 is controlled, that is, the opening of the electromagnetic valve 4 is timed, the dirt is discharged, and then the dirt accumulation caused by the staff operation is avoided.

[0037] Further, in the embodiment, the assembling structure 3 comprises a frame 31 and a first interface 32, the electromagnetic valve 4 is provided with a second interface 6, the frame 31 is connected with the discharge pipeline of the filter unit 2, the frame 31 has a mounting space for placing the electromagnetic valve 4, the first interface 32 is arranged on the frame 31, the first interface is communicated with the discharge pipeline of the filter unit 2, when the electromagnetic valve 4 is located in the mounting space, the second interface 6 is communicated with the first interface 32.

[0038] The structure of the frame 31 is shown in Figure 4 When the application is installed by the staff, a threaded pipe is arranged on the first interface 32, the frame is mounted on the filter unit 2 through the threaded pipe and the discharge pipeline of the filter unit 2, so that the dirt in the filter unit 2 can enter the frame 31 through the first interface 32, then the electromagnetic valve 4 is placed in the frame 31, and the first interface 32 is aligned with the second interface 6, so that the dirt enters the electromagnetic valve 4 through the second interface 6, when the electromagnetic valve 4 is energized, the dirt directly falls out of the electromagnetic valve 4, and the dirt is discharged.

[0039] Further, in the embodiment, the assembling structure 3 further comprises a plurality of telescopic rods 33, a plurality of clamping plates 34, a screw rod 35, a first gear 36, a second gear 37 and a knob 38, the plurality of telescopic rods 33 correspond to the plurality of clamping plates 34 one by one, the telescopic rod 33 is slidingly connected to the frame 31, one end of the telescopic rod 33 is located in the frame 31, and the other end of the telescopic rod 33 is located outside the frame 31, the clamping plate 34 is connected to the end of the telescopic rod 33 located outside the frame 31, the screw rod 35 is rotatably connected in the frame 31, the screw rod 35 is threadedly connected with the telescopic rod 33, the first gear 36 is connected with the screw rod 35, the second gear 37 is connected with the knob 38, the first gear 36 is engaged with the second gear 37, and the knob 38 is rotatably connected to the frame 31.

[0040] In order to fix the electromagnetic valve 4 more stably in the frame body 31, the application clamps the edge of the electromagnetic valve 4 through the clamping plate 34. In actual installation, the knob 38 needs to be rotated to control the rotation of the first gear 36 and the second gear 37, thereby driving the screw rod 35 to rotate, extending the telescopic rod 33, and facilitating the electromagnetic valve 4 to be put into the frame body 31. After the electromagnetic valve 4 is put in, the screw rod 35 is rotated, the telescopic rod 33 is retracted to drive the clamping plate 34 to move, and finally the clamping plate 34 is tightly attached to the outer wall of the electromagnetic valve 4, avoiding the electromagnetic valve 4 from sliding out of the frame body 31.

[0041] The assembly structure 3 further comprises a supporting plate 39, a plurality of sliding blocks 310, a plurality of positioning holes 311, a plurality of positioning members 312, and a plurality of fixing holes 313. The supporting plate 39 is arranged on the surface of the frame body 31 opposite to the first interface 32. The supporting plate 39 is connected with the sliding blocks 310. The sliding blocks 310 are slidingly connected to the frame body 31. The positioning holes 311 correspond to the sliding blocks 310 one by one.

The positioning members 312 can be inserted into the positioning holes 311 and the fixing holes 313.

[0042] The electromagnetic valve 4 has different sizes according to different models. Therefore, in order to be suitable for more models of electromagnetic valves 4, the application designs a telescopic supporting plate 39. When the size of the electromagnetic valve 4 is larger than that of the frame body 31, the positioning members 312 are pulled out of the positioning holes 311 and the fixing holes 313, and then the supporting plate 39 is moved to the appropriate position. It needs to be ensured that the first interface 32 and the second interface 6 are tightly attached to avoid dirt leakage. After the adjustment is completed, the positioning members 312 are inserted into the positioning holes 311, and the positioning members 312 are simultaneously inserted into the fixing holes 313 to fix the position of the supporting plate 39.
