The safety pin 21c protrudes toward the operation bar 25 by the rotation operation, or is in close contact with the side of the handle 21b. In the state in which the safety pin 21c protrudes toward the operation bar 25, the operation bar 25 is interfered with when the operation bar 25 is rotated to prevent the operation bar 25 from being rotated and overlapped with the handle 21b.

Therefore, the high pressure liquid for cleaning is prevented from being sprayed by the inadvertent rotation of the operation bar 25.

In addition, the auxiliary handle 90 is provided on the main pipe (10).

The auxiliary handle 90 is coupled to the sleeve tube 91 inserted into the main tube 10 and slid, the pressure fixing bolt 92 is coupled through the outer surface of the sleeve tube 91 and pressurizes the outer surface of the main tube 10. ) And an auxiliary handle 93 extending from the sleeve tube 91.

Unexplained reference numeral 26 denotes a closure member for shielding the upper end of the communication hole 21a, and reference numeral 27 denotes a packing member for watertightness.

Referring to FIG. 3, the rotation force generating unit 40 is installed at the other side of the main tube 10, and has a second housing 41 having a hollow interior in communication with the first transfer path 11 of the main tube 10. And a rotating shaft 42 rotatably installed in the hollow interior of the second housing 41 to form a third transfer path 42a communicating with the first transfer path 11 of the main tube 10.

The first branch pipe 30 is connected to the second housing 41 so that the high pressure liquid transferred through the first branch pipe 30 flows into the second housing 41. A discharge port 42a is formed in the second housing 41 so that the high pressure liquid introduced into the second housing 41 is discharged to the outside of the second housing 41. The discharge port 42a is formed on the outer surface of the second housing in the axial direction of the rotation shaft 42.

An impeller 42b is formed on the outer surface of the rotating shaft 42 to interfere with the high pressure liquid transferred through the first branch pipe 30 connected to the second housing.

The injection nozzle 50 is fixed to the rotation shaft 42, and a plurality of injection holes 51 communicating with the third transfer path 42a of the rotation shaft 42 are formed radially.

Meanwhile, referring to FIGS. 1 and 4, when the first transport path 11 of the main pipe 10 is shielded by the opening and closing means 20, the high pressure liquid in the inflow pipe 60 is branched and discharged. The second branch pipe 70 is coupled to the first housing 21. In addition, a connection pipe 28 is formed in the first housing 21 to connect the inflow pipe 60 and the second branch pipe 70.

The pressure regulating valve 80 is installed in the first housing 21 to adjust the opening amount of the connection pipe 28 to adjust the amount of high pressure liquid transferred to the connection pipe 28.

Pressure control valve 80 is installed to be slidable through the first housing 21, the opening and closing control pin 81 to enter or withdraw in the connection pipe 28 to adjust the opening amount of the connection pipe 28 and The second elastic member 82 elastically supporting the opening / closing control pin 81 with respect to the first housing 21 and the opening / closing control pin 81 by pressing the opening / closing control pin 81 are connected to the connecting pipe ( 28) a plug 83 for controlling the moving distance to be drawn in or drawn out.

Hereinafter, the operation of the present embodiment configured as described above will be described.

The high pressure liquid for washing pumped by the pumping means is transferred through the inlet pipe 60 to reach the first housing 21. In this case, when the main pipe 10 and the first branch pipe 30 are shielded by the opening / closing means 20, the high pressure liquid passes through the connecting pipe 28 in the first housing 21 for the second minute. It is transferred to the engine 70 and discharged to the outside.

Then, the transfer amount of the high pressure liquid introduced into the connection pipe 28 by the pressure control valve 80 of the connection pipe 28 is adjusted to control the discharge pressure of the high pressure liquid.

On the other hand, in the state where the high pressure liquid reaches the first housing 21 through the inlet pipe 60, the operating bar 25 is rotated so as to overlap the handle 21b.

The extension bar 23 interferes with the rotation of the operation bar 25 and slides, and the opening / closing member 22 connected to the extension bar 23 slides in the communication hole 21a in the first housing 21.

At this time, the first, second and third through holes 22b, 22c, and 22d provided in the opening / closing member 22 are connected to the communication hole 21a of the first housing 21 and the first branch pipe ( 30), the inlet pipe 60 is located in line with each other, and the hydraulic pipe 60, the main pipe 10, and the first branch pipe 30 communicate with each other. Therefore, the high pressure liquid of the inlet pipe 60 passes through the third through hole 22d of the opening / closing member 22, and most of the high pressure liquid passes through the first through hole 22b to allow the first conveying path 11 of the main pipe 10 to be carried out. ), The remainder is passed through the central hollow portion 22a of the opening and closing member 22 and passing through the second through hole 22c to the first branch pipe 30.

The high pressure liquid introduced into the first conveying path 11 of the main pipe 10 passes through the third conveying path 42a of the rotary shaft 42 communicated with the first conveying path 11, and thus, the injection nozzle 50. It is injected at a predetermined injection pressure (approximately 1500 to 2000 bar) through the hole 51.

The high pressure liquid introduced into the first branch pipe 30 is discharged into the second housing 41 to interfere with the impeller 42b of the rotating shaft 42. At this time, the rotating shaft 42 is rotated. Then, the high pressure liquid introduced into the second housing 41 is discharged to the injection nozzle 50 through the discharge port 41a.

The injection nozzle 50 is rotated at approximately 2500 to 3000 rpm by the rotation of the rotary shaft 42. Therefore, the high pressure liquid injected through the injection hole 51 of the injection nozzle 50 forms a vortex type.

Therefore, the high pressure liquid sprayed in the vortex type hits the washing object in various directions, thereby improving the washing effect.

On the other hand, when the high pressure liquid is injected through the injection nozzle 50, as mentioned above, a portion of the high pressure liquid is branched from the inlet pipe 60 through the connecting pipe 28 in the first housing 21. It is transported to the second branch pipe 70 and discharged to the outside, by controlling the discharge amount by the pressure control valve 80, it is possible to adjust the injection amount of the high-pressure liquid discharged through the injection nozzle (50).

On the other hand, when the pressing force applied to rotate the operation bar 25 is removed, the extension bar 23 and the operation bar 25 is returned to its original position by the first elastic member 24. At this time, the opening and closing member 22 is moved in the reverse direction, the main pipe 10 is connected to the communication hole (21a) of the first, second and third through-holes 22b, 22c, 22d of the first housing 21 The first branch pipe 30 and the inlet pipe 60 are not located in line with each other, so that the hydraulic pipe 60, the main pipe 10, and the first branch pipe 30 are shielded.

At this time, the injection of the high pressure liquid through the injection nozzle 50 is stopped, as mentioned above, the high pressure liquid is transferred to the second branch pipe 70 through the connecting pipe 28 in the first housing 21. It is discharged to the outside.

The embodiments of the present invention described above should not be construed as limiting the technical spirit of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms.
