[0025] It also contains:

[0026] A liquid passage 5, wherein the liquid passage 5 is movably arranged in the liquid discharge cylinder 3, and a rubber pad 16 is fixedly arranged on the upper end of the liquid passage 5. The rubber pad 16 can not only improve the sealing performance when the upper end of the liquid passage 5 conflicts with the connector 2, but also provide force buffering when the upper end of the liquid passage 5 conflicts with the connector 2. A stabilizing frame 15 is fixedly sleeved on the liquid passage 5, and the end of the stabilizing frame 15 is movably arranged in a guide groove provided on the inner wall of the liquid discharge cylinder 3. The stabilizing frame 15 can improve the stability of the liquid passage 5 in the liquid discharge cylinder 3. Two partitions 17 are fixedly arranged in the liquid passage 5, and a plurality of liquid passage ports 6 are provided on the upper and lower sides of the upper partition 17 on the outer ring wall of the liquid passage 5, and a No. 1 liquid passage groove 7 matching the liquid passage port 6 is provided in the bottom wall of the liquid discharge cylinder 3;

[0027] A cone head 8, wherein the cone head 8 is screwed on the lower end of the liquid passage pipe 5 through a sealed bearing, a No. 2 liquid passage groove 9 is provided in the cone head 8, a number of No. 1 liquid outlet holes 10 intersecting with the No. 2 liquid passage groove 9 are provided on the side wall of the cone head 8, and a number of No. 2 liquid outlet holes 11 intersecting with the No. 2 liquid passage groove 9 are provided on the outer ring wall of the liquid passage pipe 5 at a position above the lower partition plate 17;

[0028] The motor 12 is fixedly mounted on the inner bottom wall of the liquid passage tube 5. The output shaft of the motor 12 is movable through the bottom wall of the liquid passage tube 5 and connected to the cone head 8. The liquid passage tube 5 is provided with a clearing mode switching mechanism 13;

[0029] The blocking mode switching mechanism 13 comprises:

[0030] A fixed disk 13-1, wherein the fixed disk 13-1 is fixedly sleeved on the liquid pipe 5, and a spring 13-2 is movably sleeved on the liquid pipe 5, and the upper and lower ends of the spring 13-2 are respectively connected to the fixed disk 13-1 and the liquid discharge cylinder 3;

[0031] The induction switch 13-3 is fixedly arranged on the inner wall of the liquid discharge cylinder 3, and the induction switch 13-3 is matched with the lower part of the fixed disk 13-1 and is set in conflict. The induction switch 13-3 is electrically connected to the motor 12. A plurality of guide rods 13-4 are fixedly arranged on the upper end of the liquid passage tube 5. The guide rods 13-4 are movably inserted on the connector 2. A sealing ring 14 is fixedly sleeved in the annular groove provided on the outer ring wall of the fixed disk 13-1, and the sealing ring 14 is set in conflict with the inner wall of the liquid discharge cylinder 3. The sealing ring 14 can improve the sealing between the fixed disk 13-1 and the liquid discharge cylinder 3 to prevent water from penetrating into the lower position of the fixed disk 13-1 and affecting the induction switch 13-3.

[0032] When using the utility model, the cone head 8 and the liquid outlet cylinder 3 are extended into the pipeline of the evaporation crystallizer. At this time, the high-pressure water flows into the liquid outlet cylinder 3 through the water pipe 1 and the connector 2, and the liquid through port 6 below is not connected with the No. 1 liquid through slot 7, so that the high-pressure water flow will be sprayed out from the liquid outlet port 4 to clean the blockage in the pipeline. When a more stubborn blockage appears in the pipeline and cannot be quickly cleaned only by the high-pressure water flow, the cone head 8 can be made to contact the blockage, and pressure is applied to the water pipe 1 and the connector 2, so that the connector 2 drives the liquid outlet cylinder 3 to move closer to the cone head 8, and the fixed disk 13-1 drives the spring 13-2 to stretch, and the induction switch 1 3-3 will also break away from the conflict with the fixed disk 13-1 and start the motor 12. The motor 12 drives the cone head 8 to rotate, so that the cone head 8 can break and clean the blockage. In this process, the upper end of the liquid tube 5 will also conflict with the connecting head 2, and the liquid ports 6 on both sides will be connected with the No. 1 liquid tank 7. At this time, the high-pressure water flow will flow directly into the liquid tube 5 through the connecting head 2, and flow through the upper liquid port 6, the No. 1 liquid tank 7, the lower liquid port 6 and the No. 2 liquid outlet 11 to the No. 2 liquid tank 9 in turn, and finally spray out from the No. 1 liquid outlet 10, so as to assist the cone head 8 in cleaning the more stubborn blockages through the impact of the high-pressure water flow.

[0033] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0034] 1. Through the cooperation of the liquid pipe 5, the cone head 8, the motor 12 and the clearing mode switching mechanism 13, the blockages attached to the inner wall of the pipeline can be flushed only by the impact of the water flow, and the more stubborn blockages in the pipeline can be broken, so as to achieve the dredging of the pipeline and improve the clearing efficiency;

[0035] 2. The sealing ring 14 can improve the sealing between the fixed disk 13-1 and the liquid discharge cylinder 3, thereby preventing water from penetrating into the lower position of the fixed disk 13-1 and affecting the induction switch 13-3.

[0036] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
