The movable iron core 23 of the electromagnet 21 separates from the flexible hose 9 to allow the wash water to move through the flexible hose 9, and when the electric power is cut off, the permanent magnet 22 and the movable iron core 23 of the electromagnet 21 move. The movable iron core 23 of the electromagnet 21 that has sucked and pressed the flexible hose 9 presses the flexible hose 9 and blocks the movement of the wash water through the flexible hose 9.

At this time, since the motor 3 continuously drives the pump 4 to pump the cleaning liquid to the flexible hose 9 side, when the movement of the cleaning liquid is blocked by the control valve 20, naturally, The cleaning liquid does not jet from the cleaning nozzle 6. During this time, the cleaning liquid blocked by the control valve 20 is compressed and stored in the flexible hose 9. Further, when the movement of the cleaning liquid is permitted by the control valve 20,

Can be strengthened. In particular, it is more effective to use the elastic force in the flexible hose 9. In this way, by intermittently spraying the cleaning liquid, the cleaning site is hit with the cleaning water, the cleaning power is improved, and the user can be given a sufficient sense of cleanliness. Further, in the present embodiment, a bellows-shaped expandable and contractible tank is used as the cleaning liquid tank 7, but in the case of carrying out the present invention, a predetermined capacity, for example, 100 cc.
Even if the cleaning liquid tank 7 has a fixed capacity equal to or less than that, the cleaning efficiency can be improved by increasing the cleaning efficiency, and the user can be given a sufficient sense of cleanliness.

When the cleaning is completed, the projection 11a of the operating member 11 is operated to turn off the slide switch 10,
The cleaning liquid remaining in the cleaning liquid tank 7 is discarded. When the slide switch 10 is turned off, the electric power of the motor 3 and the electromagnet 21 is cut off, the movable iron cores of the permanent magnet 22 and the electromagnet 21 are attracted, the flexible hose 9 is pressed by both, and the cleaning water passing through the flexible hose 9 is washed. Is blocked, and even if there is cleaning liquid remaining in the cleaning liquid tank 7,
Leakage of the cleaning liquid from the cleaning nozzle 6 is eliminated. In this state, the cleaning nozzle 6 is housed in the nozzle guide 5 of the case base 1A. In addition, the recessed line 14 of the case base 1A and the protruding line 13 of the case moving part 1B are in a fitted state or the recessed line 15 and the protruding line 1
