Description

[Detailed Description of the Invention] The present invention relates to a cleaning pump that uses water pressure to clean a clogged drainage pipe and allows water to flow therethrough.

Conventionally, drain pipes have been cleaned by inserting a flexible wire into the pipe or cleaning with chemicals, but the former method has the disadvantage that it is difficult to clean bent pipes and damages the inner wall of the pipe. In the latter case, chemicals must be selected depending on the material of the pipe, and large blockages require time.

Therefore, the inventor of the present invention discovered that by using water pressure and water from the tap water, it is possible to solve the drawbacks of the above-mentioned conventional technology and clean the clogged pipe.

As shown in FIG. 8, an abacus-shaped bulge 33 with a slightly larger diameter than the inner diameter of the insertion chamber 14 of the rubber cylinder 1 is provided to prevent this bulge. An annular protrusion 34 is connected to the lower side wall of the insertion chamber 14 of the rubber cylinder body 1 through a constriction part 35 below the part 33 to prevent the middle cylinder 6 from slipping out due to water pressure. It is cylindrical.

As shown in FIG. 1, the valve seat 7 is constantly pushed upward by the spring 8 and comes into contact with the upper contact edge 20 of the rubber cylinder 1 until the water pressure reaches a certain level. It comes into contact with the upper contact edge 20 of the cylindrical body 1 to store water in the water storage chamber 17, and when the water pressure exceeds a certain pressure, the valve seat 7 is pushed down by the water pressure and functions to discharge water. As shown in FIG. 9, a flange 36 having a slightly larger diameter than the inner diameter of the working chamber 19 of the rubber cylinder 1 is formed, and a spring 8 is screwed into the center of the lower part of the flange 36.

Next, a method for assembling the cleaning pump of the present invention will be explained.

Insert the valve seat 7 from the water outlet 24 of the rubber cylinder 1 with the flange 36 facing upward, and after installing the valve seat 7 into the working chamber 19, insert the spring 8 from the water outlet 24, and first insert the valve seat 7 into the working chamber 19. The spring 8 is screwed onto the leg 37 of the valve seat 7
The lower end of the spring 8 is locked to the projecting peripheral wall 23 of the storage chamber 22, and the spring 8 is installed inside the storage chamber 22. The lower cap 5 is inserted into the lower tube portion 18 of the cylinder body 1 until the bottom edge 32 of the lower cap 5 comes into contact with the lower end of the lower tube portion 18.

The middle tube 6 is inserted from the water inlet 12 of the rubber cylinder 1 with the annular projection 34 facing down, and the middle tube 6 is installed in the insertion chamber 14.

After inserting one end of the hose 9 into the fixed part 25 of the hose fitting 2, the fixed part 25 is caulked,
The hose 9 is fixed to the hose fitting 2.

The tightening fitting 4 is fitted into the constriction part 13 of the rubber cylinder 1, and the connecting fitting 3 is fitted into the crown part 11 of the cylinder 1 with the inner edge 30 facing down, and the inner edge 30 is inserted into the tightening fitting 4.
into the upper part of the fixing part 27. After that, the fixed part 27 of the fastening fitting 4 is caulked to form an annular groove 40 and a locking edge 28, so that the connecting fitting 3 does not come off.
The connecting fitting 3 is attached to the state in which it is fitted into the tightening fitting 4.

The male threaded part 26 of the hose fitting 2 to which the hose 9 is fixed is screwed onto the female threaded part 29 of the connecting fitting 3,
The hose 9 is attached to the rubber cylinder 1 to be in the state shown in FIG.

Next, a method of using the cleaning pump of the present invention will be explained.

After attaching the hose 9 to the water faucet, insert the cleaning pump into the clogged pipe 38 in the washroom, etc.
When you turn on the water faucet and pour water into the cleaning pump,
Water passes through the hose 9, the water inlet 12, and the middle tube 6, and accumulates in the water storage chamber 17 of the body 16 of the rubber tube 1. When the water injection is continued, the body 16 expands, the protruding peripheral part 15 of the body 16 comes into contact with the inner peripheral wall of the pipe 38, and the cleaning pump is fixed inside the pipe 38.
The state will be as shown in FIG.

If water is continued to be injected in this state, the valve seat 7 will eventually become unable to withstand the water pressure and will be pushed downward, and at the same time, the water will spread the peripheral wall of the working chamber 19.
The water is ejected through the storage chamber 22 and the water outlet 24.

When water spouts out to a certain extent, the water pressure on the valve seat 7 decreases more than the force of the spring 8 pushing the valve seat 7 up.
The valve seat 7 rises due to the elastic force of the spring 8, and the upper outer circumferential surface of the flange 36 of the valve seat 7 touches the upper contact edge 2 of the working chamber 19.
It is pressed to 0 and water stops gushing out. Then, water accumulates in the water storage chamber 17 again, the shell 16 expands to the full inner diameter of the pipe 38, and when the pressure exceeds a certain level, the valve seat 7 is lowered and water is injected again, causing the cleaning pump and the pipe 38 to become clogged. 39 is filled with water.

By repeating this operation, the filling 3 is pushed out by water pressure.
9 is washed away and the pipe 38 is cleaned so that water can pass through it.

After this cleaning, close the tap and stop the water injection.
While gradually loosening the hose 9 attached to the water faucet, the water accumulated in the water storage chamber 17 is gradually drained, the body 16 is made thinner, and the cleaning pump is pulled out from the pipe 38 to complete the cleaning work.

In this way, the cleaning pump of the present invention inflates the rubber cylindrical body 1 with water pressure and then injects water for cleaning. Therefore, the cleaning pump of the present invention can be easily cleaned without damaging the inner wall of the pipe 38. can.

Since a rubber cylinder 1 is used in which a valve seat 7 that is constantly pushed up by a spring 8 is housed in an operating chamber 19, the body 16 of the cylinder 1 expands due to water pressure, and the washing pump is connected to a pipe 38. The pipe 38 can be easily cleaned by disposing the pipe 38 at an arbitrary position.

Since the cleaning pump can be disposed at any arbitrary position on the pipe 38 to clean the pipe, it has an excellent effect of simplifying the cleaning of a pipe that has many bends.
