The end of the first sliding rod 26 located on the outside of the fixed sleeve 25 is fixedly connected with the extrusion disk 27. The outer peripheral side of the first sliding rod 26 located on the outer side of one end of the fixed sleeve 25 is provided with a second sealing rubber ring 28, and the extrusion disk 27 and the second sealing rubber ring 28 are fitted. The fixed sleeve 2 A second sliding rod 29 is gap-fitted at one end of the inner side away from the second ventilation slot, and one end of the second sliding rod 29 close to the first sliding rod 26 is plug-fitted with the first sliding rod 26. Four fixed push blocks 30 are fixedly connected and arranged in a circumferential array on the outer side of the second sliding rod 29. A spring 31 is arranged on the outer side of the first sliding rod 26 located on the inner side of the fixed sleeve 25, and one end of the spring 31 is fixedly connected to one end of the inner side of the fixed sleeve 25, and the other end of the spring 31 is fixedly connected to one end of the four fixed push blocks 30 close to the fixed sleeve 25. A push rod 32 is arranged at one end of the second sliding rod 29 away from the fixed sleeve 25, and the end of the push rod 32 close to the second sliding rod 29 is extruded and fitted with the second sliding rod 29, and the end of the push rod 32 away from the second sliding rod 29 extends to the outer side of the gun body 1.

[0046] Specifically: by pulling the push handle 9, the push handle 9 can drive the push rod 8 to slide inside the air pumping tube 6, and through the setting of the push rod 8, the air inside the air pumping tube 6 is squeezed to the inside of the air storage tube 10;

[0047] During the extrusion process, the air inside the air pumping tube 6 will first pass through the inner side of the fixed hollow column 23 plugged into the air outlet of the air pumping tube 6, and push the sliding blocking column 24 inside the fixed hollow column 23 to a state of being in contact with the first ventilation groove of the sliding extrusion ring 22. Due to the different sizes of the two ends of the holes inside the fixed hollow column 23, the sliding blocking column 24 is close to the first ventilation groove and is located at the end with the larger hole inside the fixed hollow column 23, thereby not causing a blocking effect on the inner side of the fixed hollow column 23. At the same time, when there is airflow pushing back and driving the sliding blocking column 24, the sliding blocking column 24 can be moved back to the inner side of the fixed hollow column 23 and block the smaller hole inside the fixed hollow column 23, thereby achieving the effect of preventing air from returning. At the same time, through the setting of the first sealing rubber ring 21, a sealing effect can be played between the sliding extrusion ring 22 and the second connecting tube 16, thereby preventing air from leaking from the inner side of the air storage tube 10 and affecting the pressure inside the air storage tube 10.

[0048] At this time, the air squeezed from the inside of the air pumping pipe 6 will pass through the first ventilation slots formed by the fixed hollow column 23 and the sliding squeeze ring 22, and flow to the inside of the sliding cylinder 15 with a clearance fit inside the first connecting pipe 14. The air squeezes the notch formed inside the sliding cylinder 15, so that the sliding cylinder 15 can move inside the first connecting pipe 14 toward the end away from the fixed cap 13. Then, the end of the sliding cylinder 15 close to the exhaust pipe 11 will fit the port of the exhaust pipe 11 and block the port of the exhaust pipe 11. At the same time, the end of the sliding cylinder 15 away from the exhaust pipe 11 is not completely separated from the inside of the first connecting pipe 14.

[0049] At the same time, by setting the outer peripheral side of the sliding cylinder 15 away from one end of the exhaust pipe 11 with a smaller diameter, at this time, the end of the sliding cylinder 15 located inside the first connecting pipe 14 will leave a gap with the first connecting pipe 14, and the air will enter the inner side of the air storage pipe 10 through the gap between the sliding cylinder 15 and the first connecting pipe 14. Since the sliding cylinder 15 blocks the exhaust pipe 11, the inner side of the air storage pipe 10 can become a closed space. As the air push rod 8 continues to push the air into the inner side of the air storage pipe 10, the air pressure inside the air storage pipe 10 will gradually increase, and the strong air pressure will fix the position of the sliding cylinder 15, so that the sliding cylinder 15 can continue to block the exhaust pipe 11.

[0050] At this time, the bottom of the barometer 19 will detect the air pressure inside the air storage pipe 10 through the connection setting of the connecting hose 20, the third connecting pipe 17 and the fixing cap 13, and display it to the staff;

[0051] At the same time, the air pressure inside the air storage tube 10 will also pass through the connecting position between the fourth connecting tube 18 and the fixed cap 13, and push the extrusion plate 27. At this time, the second sealing rubber ring 28 can produce a sealing effect on the second ventilation groove opened by the first sliding rod 26 and the fixed sleeve 25, so as to prevent the air inside the air storage tube 10 from leaking through the fixed sleeve 25 and the fourth connecting tube 18, thereby further improving the sealing effect of the air inside the air storage tube 10.

[0052] At the same time, by setting the spring 31, the second sliding rod 29 can be continuously pushed toward the end away from the first sliding rod 26 through the extrusion setting between the spring 31 and the fixed push block 30, so as to achieve the effect of limiting the second sliding rod 29, and avoid the second sliding rod 29 approaching the first sliding rod 26 and pushing the first sliding rod 26 to affect the air sealing of the second sealing rubber ring 28 during use;

[0053] When the barometer 19 shows that the air pressure inside the air storage tube 10 has reached a usable level, the push rod 32 on the outside of the gun body 1 can be pushed and the push rod 32 can be pushed toward the inside of the gun body 1. At this time, the end of the push rod 32 close to the second sliding rod 29 will drive the second sliding rod 29 to move synchronously toward the inside of the fixed sleeve 25, and the end of the second sliding rod 29 close to the first sliding rod 26 will be plugged into the first sliding rod 26. Then, the first sliding rod 26 is driven by the second sliding rod 29 to move synchronously, so that the first sliding rod 26 can drive the extrusion plate 27 to move toward the end away from the fixed sleeve 25. At this time, the extrusion plate 27 loses the squeezing effect on the second sealing rubber ring 28, which will cause the second sealing rubber ring 28 to loosen, thereby reducing the sealing effect of the loose second sealing rubber ring 28 on the gap. When the air passes through the second ventilation groove opened by the fixed sleeve 25, the air inside the air storage tube 10 will be turbulent, and drive the sliding cylinder 15 to move to the inside of the first connecting tube 14. At this time, the exhaust pipe 11 will become a larger ventilation hole inside the air storage tube 10, and guide the air inside the air storage tube 10, and then discharge it through the spherical port at the end of the air storage tube 10, so as to achieve the effect of clearing the pipeline through high-intensity air.

Specifically, Figure 10-11 As shown, the unclogging end assembly 5 includes a first unclogging head 33, which includes a first hollow connecting tube 35 and a sealing film 36. A first spherical slot is opened on the inner side of one end of the first hollow connecting tube 35, and a plurality of sealing films 36 are fixedly connected from large to small on the outer side of the end of the first hollow connecting tube 35 away from the first spherical slot.

[0057] The first hollow connecting pipe 35 is set to be 210mm in length, 104mm in outer diameter, and 8mm in inner diameter. It is made of a soft material, such as rubber, and can adapt to the curvature of the pipe.

[0058] At the same time, the plurality of plugging soft sheets 36 are configured as soft discs gradually smaller in diameter from 110 mm to 62 mm, and the material is the same as that of the first hollow connecting tube 35, and the interval between each two plugging soft sheets 36 is the same;

[0059] By setting a plurality of plugging soft films 36, compared with the traditional spherical dredging ports on the market, it can be applied to pipes of different thicknesses, improve the airtightness between pipes, and thus improve the effect of dredging the pipes;

[0060] At the same time, by providing a plurality of plugging soft films 36, the splash caused by the airflow pushing the liquid in the pipeline during the pipeline dredging can be greatly reduced, thereby improving the overall cleanliness during the use of the pipeline dredging device.
