Description

Technical Field

[0002] A trap refers to a fitting with a water seal installed inside a sanitary appliance or on the drainage pipe section of the appliance. Traps are divided into S-type traps, P-type traps, and U-shaped traps. S and P, and U can vividly illustrate the shape of the trap.

[0003] In drainage pipes, in order to ensure fluidity, the inner diameter of the drainage main pipe is generally set larger than the inner diameter of each discharge input pipe. However, in order to prevent the odor from the sewer from flowing back, a trap pipe is generally installed between the discharge input pipe and the drainage main pipe. When the water flows through the trap, it will be decelerated. This makes it easy for many debris that can pass through the discharge input pipe and the drainage main pipe to be decelerated inside the trap pipe and cause blockage.

[0042] Working principle:

[0043] When performing common dredging, firstly, the input end of the connecting pipe head 106 is blocked, and the pumping and pushing dredging hydraulic conduit 406 is connected to the main hydraulic conduit 407 through the electromagnetic distribution valve 405, and the precision dredging hydraulic conduit 408 is closed, and the annular electromagnet 506 and the cylindrical electromagnet 511 are energized. After the annular electromagnet 506 and the cylindrical electromagnet 511 are energized, magnetic force will be generated. By changing the current direction of the annular electromagnet 506, the polarity of the annular electromagnet 506 can be changed. When the polarity of the annular electromagnet 506 is consistent with the polarity of the cylindrical electromagnet 511, attraction is generated. When the polarity of the annular electromagnet 506 is opposite to the polarity of the cylindrical electromagnet 511, repulsion is generated. When attraction is generated, the cylindrical electromagnet 511 drives the pump piston 507 to pump. When the pump piston 507 is pulled, the hydraulic transmission drives the push piston 204 to produce a pulling action. When the push piston 204 is pulled, the negative pressure generated will pull the blockage back. When the repulsive force is generated, the cylindrical electromagnet 511 drives the pump piston 507 to push. When the pump piston 507 is pushed, the hydraulic transmission drives the push piston 204 to produce a pushing action. When the push piston 204 is pushed, the positive pressure generated will push the blockage out. The cylindrical electromagnet 506 periodically pulls the cylindrical electromagnet 511, so that the blockage can continuously move inside the water trap 101, thereby gradually loosening or crushing, until it can move smoothly and be discharged by the impacting water flow, and then the blockage at the input end of the connecting pipe head 106 is opened, thereby achieving dredging;

[0044] When precise dredging is performed, the precise dredging hydraulic conduit 408 is connected to the main hydraulic conduit 407 through the electromagnetic distribution valve 405, the push-pull dredging hydraulic conduit 406 is closed, the annular electromagnet 506 and the cylindrical electromagnet 511 are energized, and when attraction is generated, the cylindrical electromagnet 511 drives the pump piston 507 to pull, and when the pump piston 507 is pulled, the impact piston 411 is driven to produce a pulling action through hydraulic transmission, and the negative pressure generated when the impact piston 411 is pulled will draw waste water or air into the dredging external joint 301 through the flushing hole 305, and when repulsion is generated, the cylindrical electromagnet 511 drives the pump piston 507 to push, and when the pump piston 507 is pushed, the impact piston 411 is driven to produce a pushing action through hydraulic transmission, and the impact piston 411 pushes the airflow or water flow to impact the blockage at the bottom, so that the blockage moves until it is crushed or the clamping connection between the water trap 101 is released, and then the blockage is flushed away using a common dredging method, thereby achieving dredging.
