Here, FIG. 1 is a cross-sectional view of the pipe cleaning apparatus according to the present invention, FIG. 2 is a cross-sectional view of another state of the pipe cleaning apparatus, and FIG. 3 is an enlarged cross-sectional view of a main part of the pipe cleaning apparatus.

In this pipe cleaning apparatus, one end of an outer tube 2 is fixed to a block 1, and the inner tube 3 is inserted into the outer tube 2 at a distance from the inner peripheral surface of the outer tube 2 through the block 1. One end is fixed. A cleaning liquid supply passage 4 is provided between the inner and outer double outer tubes 2 and the inner tube 3, and an air supply passage 5 is provided inside the inner tube 3.

A cleaning liquid injection nozzle 6 is screwed to the distal end of the outer tube 2, and a holder collar 7 is fitted on the inner peripheral surface of the base of the cleaning liquid injection nozzle 6. An air injection nozzle 8 is fitted into the distal end of the inner tube 3 and screwed into the distal end of the cleaning liquid injection nozzle 6. The outer diameter of the cleaning liquid injection nozzle 6 is set so that a gap between the inner diameter of the cleaning pipe 11 and the inner diameter of the pipe 11 to be cleaned can secure the flow velocity of air.

The cleaning liquid jet nozzle 6 has a jet port 6a for jetting the cleaning liquid to the rear side, a jet port 6b for jetting the cleaning liquid substantially to the front side, and an jet port 6b for jetting the cleaning liquid substantially in the front center direction. And a jet port 6d for jetting the cleaning liquid forward. A jet port 8a for jetting air forward in the center of the air jet nozzle 8;
The air outlets 8b and 8c for blowing air substantially forward and to both sides are formed.

A valve 9 is slidably fitted between the inner peripheral surface of the cleaning liquid injection nozzle 6 and the outer peripheral surface of the tip of the inner tube 3. The valve 9 closes the supply path 6e to the jet ports 6b to 6d of the cleaning liquid jet nozzle 6 when air is blown from the air jet hole 3a at the tip of the inner tube 3, and the jet ports 8a to 8c of the air jet nozzle 8 To open the supply path to the

In the pipe cleaning apparatus configured as described above, the cleaning liquid supply passage 4 between the block 1 and the outer tube 2 and the inner tube 3 as shown by an arrow in FIG.
When the cleaning liquid (for example, water) is supplied to the air supply passage 5 in the inner tube 3 and the air is not supplied, the valve 9 is pushed by the pressure of the cleaning liquid as shown in the right half of FIG. Outlet 6 of cleaning liquid spray nozzle 6
Since the supply path 6e to b to 6d is opened and the supply path to the ejection ports 8a to 8c of the air ejection nozzle 8 is closed, the ejection paths 6a to 6d of the cleaning liquid ejection nozzle 6 move in the respective directions as shown in FIG. A cleaning liquid is injected.

Therefore, by inserting the pipe cleaning device into the pipe 11, the inner peripheral surface of the pipe 11 is cleaned with the cleaning liquid jetted from the cleaning liquid jet nozzle 6, and the jet port 6b near the bottom 11a of the pipe 11. 6d, the cleaning liquid is sprayed to the front side.
