Description

Water pipe cleaner

The present invention relates to a pipe cleaner, in particular to a water replenishing pipe cleaner.

The conventional pipe cleaners that utilize gas pressure differential are designed to squeeze the gas inside the disc because gas is compressible. The pressure exerted by the gas on the residual water and blockages inside the pipe is small, and it is difficult to remove blockages in the drainage pipe of the toilet, so this type of pipe cleaner is not very effective in practice.

Therefore, the applicant has designed a hydraulic pipe cleaner as disclosed in TW I292806 patent. Please refer to FIG. 1 and FIG. 2. The hydraulic pipe cleaner 1 has a piston 11 and a space 12 for containing water disposed in a pipe body 10. An impact plate 13 is disposed in the pipe body 10. The impact plate 13 is connected to a push tube 14 and passes through the top end of the pipe body 10. A force-applying handle 15 is disposed at the top end of the push tube 14. When the pipe is being cleaned, the piston 11 can be used to push the push tube 14 to the top end of the pipe body 10. The water previously contained in the pipe body 10 is first replenished and injected into the drainage pipe of the toilet, so that the drainage pipe to the pipe body 10 of the water pressure pipe cleaner 1 is filled with water. When the impact force of hitting or pushing the force-applying handle 15 directly hits or pushes the piston 11 through the impact plate 13, and then the piston 11 pushes the water inside the pipe body 10, so that the impact force can be transmitted to the drainage pipe through the water to push the blockage.

However, when the force-applying handle 15 is tapped or pushed, since the piston 11 in the tube body 10 is not completely airtight and there is still some air in the tube body 10, the water between the drainage pipe and the tube body 10 of the hydraulic pipe cleaner 1 is not completely full. A part of the air in the tube body 10 must be pressed out before the water can be pressed out, resulting in insufficient pressure of the pressed water and failure to smoothly pressurize and clear the blockage in the drainage pipe. Therefore, the hydraulic pipe cleaner 1 has the above-mentioned defects and needs further improvement.

The main purpose of the present invention is to solve the problem that the existing hydraulic pipe cleaner is prone to the problem that the piston in the pipe body is not completely airtight, so that part of the air in the pipe body cannot be completely filled with water, resulting in insufficient pressure of the squeezed water.

The connecting pipe 96 includes a first joint 961 that is sleeved on the second convex joint 952 and connected to the water outlet 9521, and a second joint 962 that is sleeved on the first convex joint 65 and connected to the water inlet 650, wherein the first joint 961 has a gasket 963 located between the first joint 961 and the second convex joint 952 and makes the first joint 961 sleeved tightly, and an internal thread 9621 is provided on the inner periphery of the second joint 962 and is threadedly connected to the external thread 651 of the first convex joint 65.

Referring again to the embodiment of FIG. 7 to FIG. 12 and FIG. 13, when the user uses the water supply pipe cleaner 2 to clear the blockage A2 inside the drainage pipe A1 of the toilet A, for example, the flow chart of the preparation action of the water supply pipe cleaner 2 before use is shown. The user holds the upper cover 84 and rotates the water supply pipe 71 in a counterclockwise direction until it stops. At this time, the venting pressure relief hole 811 is connected to the main pipe 4, and the upper cover 84 is removed. , inject tap water into the inner hollow 70 of the water supply pipe 71 until it is full of water (as shown in Figure 8), cover the upper cover 84 again, and the plug 846 covers the vent hole 844 (as shown in Figures 9 and 10), and place the suction nozzle 66 below the main pipe 4 into the drain port A11 of the toilet A. The vent pressure relief pipe 81 will allow the blocked residual water to smoothly enter the main pipe 4, and the blocked water level will not rise. The main pipe 4, and tightly block the drain outlet A11 of the toilet A. The upper cover 84 is rotated clockwise to the other side position, as shown in Figures 11 and 12. At this time, the outlets 912 at the bottom of the water supply pipe 71 will be aligned with the water outlet 9521 of the lower cover seat 95. The plug 846 of the vent hole 844 is removed and placed in the receiving hole 847. The water in the water supply pipe 71 can be smoothly discharged. After entering the inner hollow 41 of the main pipe 4 through the water outlet 9521 and the water inlet 650, the handle 52 is pulled up to a fixed position, and the remaining water in the water supply pipe 71 is injected into the extra space in the main pipe 4 due to the upward movement of the handle 52, until the water level of the main pipe 4 is aligned with the water level of the water supply pipe 71. At this time, the water supply pipe clearer 2 is ready for blocking, clearing and impacting.

Referring again to FIG. 13 and FIG. 14, when the preparation of the water supply pipe clearer 2 is complete, the pipe clearing process can be carried out. One hand holds the second gripping portion 5441 of the horizontal gripping handle 544 to stabilize the main pipe 4 and slightly press down. The other hand holds the first gripping portion 521 of the handle 52 and uses a momentary and rapid downward pressure to quickly hit the push piece 53 of the handle 52 against the piston 55. The main pipe 4 is then closed. The impact force on the horizontal surface of the pipe 4 is directly transmitted to the suction nozzle 66 at the bottom of the water supply pipe cleaner 2 through the water, and the pressure is transmitted to the deep part of the drainage pipe A1 of the toilet A where the blockage occurs. Since water is a substance that cannot be compressed, the impact force will be 100% transmitted to the deep part of the other end through the water, and the blockage A2 will be pushed inward and downward, and the blockage A2 does not know whether it is close to or far from the drainage outlet A11. If the water inside the main pipe 4 is not enough, the water supply pipe 71 must be used to supply water to the main pipe 4. When the water inside the main pipe 4 is full, the pressure generated by the water hitting the water surface through the handle 52 will be diverted to the outlets 912 at the bottom of the water supply pipe 71. At this time, the backflow of water will push the water blocker 92 upward and block the outlets 912 to prevent the backflow of water. The pressure is further increased to spray upward, and the impact action can be repeated until the drainage pipe A1 of the toilet A is blocked and cleared, or the water in the main body pipe 4 is used up by the impact. At this time, in conjunction with Figures 11 and 12, if there is still residual water in the water supply pipe 71, the preparation action can be repeated, and then the pipe can be continued to impact and open the blockage A2 in the drainage pipe A1 of the toilet A to achieve the unblocking effect.
