In this case, a convex piece or the like may be provided in the engaging portion 24b, and a restricting portion for regulating the convex piece may be provided in the nozzle portion receiving hole of the tip portion 23 so that the rotation of 90 ° or more does not occur. .

  A check valve 23k is provided between the inflow pipe 23h and the liquid filling part 23j, and a check valve 23l is provided between the outflow pipe 23i and the liquid filling part 23j. The check valve 23k is filled with liquid from the inflow pipe 23h. The check valve 23l acts so that the liquid flows only in the direction from the liquid filling part 23j to the outflow pipe 23i.

  The liquid filling portion 23j is a cylindrical piston cylinder, and a piston portion 23m that slides in and out is disposed on one side of the liquid filling portion 23j. One end of the shaft portion 23n of the piston portion 23m is hooked to the finger of the operation portion 22. The pressing part 22b of the part 22a is in contact. The finger hook portion 22a is configured to rotate around a shaft 22c. A coil spring 23o that constantly urges the piston portion 23m toward the finger hooking portion 22a is disposed between the shaft portion 23n and the surrounding wall portion.

  The tightening portion 23c is rotated so that the screw thread portion of the mouth portion B1 of the container B filled with the cleaning liquid W or water is screwed into the screw groove portion of the tightening portion 23c, and the container B is drawn to the container mounting portion 23a. And fix. At this time, the container B is fixed in an upside-down oblique state with the mouth B1 facing downward. By the rotation of the tightening portion 23c, the mouth portion B1 of the container B comes into contact with the seal portion 23e, and liquid leakage is prevented. The inlet 23f and the air inlet 23g are located between the mouth portions B1. In addition, when there is an uneasy strength to support the container B containing the cleaning liquid W only on the fastening part 23 c, the container B may be held in contact with the outer wall of the tip part 23.

  In this state, when the gripping portion 21 is gripped with one hand and the index finger is pulled on the finger hooking portion 22a, the finger hooking portion 22a rotates around the shaft 22c as shown in FIG. By this rotation, the pressing portion 22b of the finger hook portion 22a is pushed into the rear end of the shaft portion 23n of the piston portion 23m. Then, against the biasing force of the internal pressure coil spring 23o of the liquid filling part 23j, the shaft part 23n is moved forward, and the piston part 23m is pushed into the liquid filling part 23j. As a result, the internal pressure of the liquid filling part 23j increases, the cleaning liquid W flows out from the liquid filling part 23j through the check valve 23l to the outflow pipe 23i, and the cleaning liquid W moves forward from the nozzle part 24 connected to the outflow pipe 23i. Is injected into.

  When the cleaning liquid W is sprayed from the nozzle portion 24, the cleaning liquid W that passes through the main injection hole 24c is ejected in the front direction, and the cleaning liquid W that passes through the sub-injection holes 24d on both sides is sprayed so as to spread in the lateral direction. As a result, the sprayed cleaning liquid W adheres to the surface to be cleaned in a substantially straight line. The sprayed cleaning liquid W spreads in the horizontal direction and is sprayed, and the cleaning liquid W adhering to the surface to be cleaned easily cleans the surface to be cleaned by spreading over the entire cleaning surface of the cleaning portion 31b that is long in the horizontal width direction. Can do.

  Note that the cleaning liquid W is sprayed widely and far if it is moved quickly, and the cleaning liquid W does not reach narrow and far if it is moved slowly by the finger adjustment to the finger hook 22a.

  When the finger is released from the finger hooking portion 22a after the cleaning liquid W is jetted, the piston portion 23m and the shaft portion 23n are retracted to the state shown in FIG. 6 by the restoring force of the coil spring 23o. Thereby, since the inside of the liquid filling part 23j becomes a negative pressure, the cleaning liquid W in the container B is drawn into the liquid filling part 23j from the inflow pipe 23h via the check valve 23k, and the cleaning liquid W is put into the liquid filling part 23j. Is filled again. The inside of the container B from which the cleaning liquid W has been discharged has a negative pressure, and the outside air in the tip 23 enters the container B through the air inlet 23g, and the inside pressure in the container B is balanced with the outside air.

  FIG. 8 shows a sectional view of a state in which the cleaning head portion 30 is replaced from the head 31 of FIG. 1 to the head 32 of FIG. 3 and the cleaning liquid W is jetted, and as shown in FIG. The nozzle portion 24 is rotated by 90 ° so that the arrangement of the two sub-injection holes 24d is directed in the vertical direction. The sprayed cleaning liquid W spreads in the vertical direction and is sprayed, and the cleaning liquid W adhering to the target surface to be cleaned spreads over the entire cleaning surface of the cleaning portion 32b that is long in the vertical direction. For example, when sprayed onto a window sash, the cleaning liquid W adheres only to the sash, and the sash can be easily cleaned without being applied to other places.

  Further, when the head 31 is used, the container B containing the cleaning liquid W for removing dirt on the glass surface is used. When the head 32 is used, the container containing the cleaning liquid W for removing mold, dirt and the like. It is preferable to use B according to the place to be cleaned, such as using B. Of course, tap water may be used instead of the cleaning liquid W.

  In the illustrated embodiment described above, the cleaning liquid W is sprayed with the nozzle portion 24 facing downward. However, when the room ceiling or the like is used as the surface to be cleaned, the mouth B1 of the container B is directed upward. Therefore, the cleaning liquid W accumulates at the bottom of the container B and cannot flow out. In this case, a flexible tube may be connected to the inlet 23f of the container attachment portion 23a, and the tube may be suspended in the container B so that the cleaning liquid W is sucked out from the bottom of the container B.

  Further, the cleaning liquid W does not necessarily use the container B, but the attachment of the container mounting portion 23a can be changed, and a tap water can be connected to use tap water as it is.

  Further, since the sprayed cleaning liquid W can be visually confirmed, cleaning can be performed while adjusting the supply amount of the cleaning liquid W to the surface to be cleaned.
