By changing the angle between the water outlet and the fixed tube 602, the sewage discharge can be controlled. The O-type valve ball 604 can be rotated 90 degrees. The O-type valve ball 604 is mainly used to cut off, distribute and change the flow of the medium. It only needs to be rotated 90 It can be closed tightly with only a small amount of operation and torque.

[0021] An extension pipe 7 is connected to the top of the main pipe 1 and below the control component 6, and a water outlet pipe 701 is provided below the extension pipe 7. The diameters of the extension pipe 7 and the water outlet pipe 701 are both smaller than the main pipe 1, and the diameter of the water outlet pipe 701 is smaller than that of the extension pipe 7, so that the water outlet pipe 701 can drain water centrally. An annular belt 702 is connected to the outer circle of the extension pipe 7, and the annular belt 702 is fixedly connected with a top cap 703 to prevent the top cap 703 from separating from the water outlet pipe 701 and causing the top cap 703 to be lost. The top cap 703 is connected to the water outlet pipe 701 with a threaded rotation matching connection.

[0022] In summary, the use process of the device is as follows: when a dirt remover is needed, first, the main body tube 1 and the tube cap 2 on the device are rotated and separated through the external thread 101 and the internal thread 202, and then the matching filter barrel net 3 is connected through the connecting mechanism 4 on the connecting tube 301, and the thread head 402 on the part of the tube cap 2 extending from the top cover thread 401 on the connecting tube 301 and the positioning block 201 is rotated and connected, and at the same time, the fixing block 403 on the connecting tube 301 is clamped into the groove 404, and the filter barrel net 3 is double fixed to prevent the filter barrel net 3 from loosening, and then the filter barrel net 3 is connected to the inside of the tube cap 2, Then the main pipe 1 is threadedly connected with the pipe cap 2, and finally the water inlet pipe 5 on the device is rotationally connected to the HVAC pipe. At the same time, the water outlet pipe 701 is perpendicular to the ground, so that the device is fixed to the HVAC pipe. When the HVAC pipe needs to be filtered and decontaminated, the valve stem 603 connected to the handle 601 is manually controlled to rotate the O-type valve ball 604, and finally the water outlet hole of the O-type valve ball 604 is parallel up and down, so that sewage can be discharged. At the same time, the angle between the water outlet hole and the fixed pipe 602 is changed, so the sewage discharge amount can be controlled, and finally the HVAC pipe filtration and decontamination treatment is completed.
