It consists of 21 and. The emission part 20 is a direction control part with a frustum in cross section
With 22 as the center, the water discharge port 23 is on the inner peripheral side, and the cleaning liquid suction port
24 are opened on the outer peripheral side toward the mixing section 21, respectively. Water is a water supply path that reaches the water discharge nozzle 2 through the inside of the handle 7.
From 25, the cleaning liquid is supplied from a cleaning liquid supply passage 26 extending from the cleaning liquid tank 11, respectively. The mixing unit 21 includes a discharge unit 20,
A region surrounded by the peripheral wall surface 27 and the injection port 28 provided at a position facing the discharge portion 20 is formed. The injection port 28 is made of a metal mesh that is a mesh-like surface material through which water and bubbles pass, and discharges (injects) water and cleaning bubbles.

Collide with, are scattered, and are mixed with the air introduced from the air intake port 29 to form bubbles. Since the generation of bubbles due to the release and scattering of water continues as long as the water is released, the mixing section 21 is filled with bubbles. In the case of this example, since the cleaning bubbles are generated by the cleaning liquid, and the generated cleaning bubbles have a long disappearance time, the mixing section 21 is mainly filled with the cleaning bubbles. In this way, the cleaning foam filling the mixing space approaches the cleaning liquid suction port 24 and the air intake port 29.

進し、効率のよい洗浄泡の生成を実現する。The water collides with the peripheral wall surface 27 and scatters, but the flow in the discharge direction is not lost, and most of the water is discharged (jetted) from the jet port 28. At this time, the residual water forms convection in the mixing section 21 to circulate the cleaning bubbles, and the cleaning bubbles are placed on the majority of the water flow, and the cleaning bubbles are sequentially discharged from the injection port 28. In this way, a part of the cleaning bubbles filling the mixing section 21 is discharged, so that a negative pressure is generated in the space occupied by the discharged cleaning bubbles in a relative relationship with the surroundings. Even if the cleaning bubbles are discharged in the vicinity of the injection port 28, the negative pressure generated draws the bubbles and the cleaning bubbles around, so that the negative pressure reaches the periphery of the mixing section 21.
Thus, the negative pressure generated in the cleaning liquid suction port 26 and the air intake port 29 around the mixing section 21 sucks the cleaning liquid from the cleaning liquid suction port 26 and also takes in the air from the air intake port 29. Then, the scattering of water further promotes the mixing of the cleaning liquid and the air, and realizes efficient generation of cleaning bubbles.

生成しやすくしている。The swivel arm 30 has a center of gravity between a center part 33 and a tip part 32 which are always coaxial with the swivel axis 31, and swivels so that the center of gravity becomes the lowest position according to the inclination of the cleaning liquid tank 11. The arm 30 turns about the turning axis 31. Since the cleaning liquid also moves to the lowest position as the cleaning liquid tank 11 tilts,
The tip portion 32 of 30 always comes to be immersed in the cleaning liquid, and the cleaning liquid can be sent from the central portion 33 to the discharging portion 20 through the cleaning liquid supply path 26. In particular, since the water discharge nozzle 2 of this example is adapted to suck the cleaning liquid, the tip 32 of the swivel arm 30 is
As long as the cleaning liquid is in contact with the cleaning liquid, the cleaning liquid can be reliably delivered (sucked) to the discharge part 20 regardless of the inclination state of the cleaning liquid tank 11. In addition, in this example, the stirring projection 34 is erected from the injection port 28 of the mixing section 21 of the water discharge nozzle 2, and the suctioned cleaning liquid and the discharged water are dispersed in the mixing section 21, whereby water, cleaning liquid, and air are discharged. To facilitate the generation of washing bubbles.

In particular,
By using the water discharge nozzle of the present invention, it is not necessary to separately prepare a power supply for supplying the cleaning liquid necessary to generate the cleaning bubbles, while using the presence or absence of water discharge as an operation switch, while supplying an appropriate amount of cleaning liquid. It is possible to efficiently generate cleaning bubbles. In addition, the cleaning foam thus efficiently generated is filled in the flexible cover, and the cleaning foam is discharged from the gap between the slightly-formed interface cushioning portion and the surface to be cleaned. The cleaning bubbles can be reliably guided to the contact surface buffering part that contributes to polishing, and a high cleaning effect is exhibited. Furthermore, if a swivel arm having a built-in cleaning liquid supply path is provided in the cleaning liquid tank provided immediately above the water discharge nozzle, the cleaning liquid can be stably delivered regardless of the inclination of the cleaning liquid tank. As described above, the present invention has an effect of actively producing cleaning bubbles and providing a car wash tool exhibiting a high cleaning effect because the cleaning bubbles can be used without waste.
