Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing a first embodiment of the mist generator of the present invention,
FIG. 2 is a sectional view taken along the line II-II. The mist generator includes a cylindrical housing 1, a nozzle 2 is inserted into one end of the housing 1, and a disk-shaped crushing member 3 is provided at the other end of the housing 1. I have. This mist generator generates mist by finely crushing hot water to use a bathroom or the like as a simple steam bath.

The nozzle 2 is connected to a hot water supply tap via a hose H with a joint J, and the hot water supplied from the tap can be jetted to the crushing member 3 through the jet hole 2a. The diameter D1 of the injection hole 2a is set so that the injection speed of hot water can be sufficiently secured.
Is narrowed by a predetermined amount with respect to the diameter D2 of, for example, when the diameter D2 of the nozzle body 2b is 6 to 8 mm, the diameter D1 of the injection hole 2a is set to 0.5 to 3 mm. The diameter D1 of the injection hole 2a is appropriately selected in consideration of the size of the pores 3a of the crushing member 3 described later, the amount and particle size of the mist to be generated, the distance between the nozzle 2 and the crushing member 3, and the like.

The crushing member 3 is attached to the housing 1 so as to cover the entire opening at the other end of the housing 1. The crushing member 3 is formed of a net made of a synthetic resin, and a large number of the meshes are configured as pores 3 a for allowing the liquid ejected from the nozzle 2 to permeate and form mist. The opening size of the pores 3a is appropriately selected in consideration of the amount and particle size of the mist to be generated, but setting to 0.05 to 2.0 mm makes the hot water mist efficiently. It is preferable because it can be performed. The crushing member 3 can be elastically deformed in the axial direction by being hit with hot water injected from the nozzle 2.
Micro vibration can be performed in the axial direction.

In the mist generator configured as described above, the hot water jetted from the nozzle 2 is applied to the crushing member 3 and penetrated through the pores 3a, thereby crushing the hot water and efficiently forming mist. With this mist formation, steam can be efficiently generated.
In particular, in the above embodiment, the crushing member 3
Since the minute vibration is caused by the collision of the hot water, the scattering direction of the hot water can be constantly changed, and the hot water can be miniaturized more efficiently. For this reason, a large amount of mist can be generated efficiently. This mist generation efficiency is superior to that using a conventional impeller. Further, since a rotating part such as an impeller is not required, the structure of the mist generator can be extremely simplified.

The hot water sprayed from the nozzle 2 is efficiently misted as the distance to the crushing member 3 increases, but the injection pressure can be reduced by reducing the diameter D1 of the injection hole 2a of the nozzle 2. Can be raised to shorten this distance. For example, the supply pressure of hot water to the nozzle 2 is 1 kg / cm
^{2. When} the diameter D1 of the injection hole 2a of the nozzle 2 is 1 mm, the distance between the nozzle 2 and the crushing member 3 is set to 10 to 50 mm, and when the diameter D1 of the injection hole 2a of the nozzle 2 is 2 mm, the nozzle The distance between 2 and the crushing member 3 is 100 to 3
It is set to 00 mm.

The diffusion member 4 has a conical shape made of metal or synthetic resin, and has a large-diameter end attached to the crushing member 3 concentrically. The point angle θ of the diffusion member 4 is set to about 10 ° to 30 ° so that the flow rate of the hot water from the nozzle 2 does not decrease due to the resistance. The large diameter end of the diffusion member 4 is
The outer diameter of the crushing member 3 is set to about ４ to に 対 し て. According to this embodiment, the hot water sprayed from the nozzle 2 is diffused by the diffusion member 4 and
Can be used. For this reason, when the distance between the nozzle 2 and the crushing member 3 is shortened, that is, even when the distance necessary for diffusing the hot water injected from the nozzle 2 cannot be secured, the liquid is sufficiently diffused to crush the member. 3 can be applied. For this reason, the nozzle 2 and the crushing member 3
Hot water can be efficiently crushed and miniaturized while shortening the distance to the hot water, that is, reducing the size.

FIG. 4 is a longitudinal sectional view showing a third embodiment of the mist generator according to the present invention. In this embodiment, a diffusion member 4 is disposed between a nozzle 2 and a crushing member 3, and a mist that has passed through the crushing member 3 collides against the back side (left side in the figure) of the crushing member 3. A collision plate 5 for further miniaturization is arranged. The collision plate 5 has a disk shape, and its outer peripheral side is fixed to the extension 1 a of the housing 1. Further, in the extension 1a of the housing 1, through holes 1b for discharging mist in the housing 1 to the outside are provided at predetermined intervals along the circumferential direction. According to this embodiment, the liquid crushed by the crushing member 3 can be made to collide with the collision plate 5 to be further finely miniaturized. Therefore, mist can be generated more efficiently. Further, the collision plate 5 can prevent relatively large water droplets from being ejected to the outside of the housing 1. The collision plate 5 is
Of course, it can also be used in the embodiment shown in FIG. Further, the collision plate 5 may be formed integrally with the housing 1.

The crushing member 3 may be made of a wire mesh made of stainless steel or the like, a punching metal having a large number of pores, a ceramic plate through which a liquid can pass, or the like. It can be implemented in various shapes such as a hemisphere. In addition, the crushing members 3 may be arranged in a plurality of rows along the hot water jetting direction. In this case, the coarseness of each crushing member 3 may be gradually reduced toward the hot water jetting direction. . The present invention can be applied to not only the above-described mist generator for a simple steam bath but also a mist generator used for a facial beauty device, a humidifier, a sprayer, and the like. Further, as the liquid to be mist, various liquids such as water, oil, solvent, detergent and the like can be used in addition to steam hot water.

[0018]

As described above, according to the mist generator according to the first aspect, the liquid ejected from the nozzle is crushed by impinging the crushing member on the crushing member and passing through the pores. Since a mist can be formed, a rotating member such as a conventional impeller is not required, and mist can be efficiently generated with an extremely simple structure.

According to the mist generator according to the second aspect, the liquid jetted from the nozzle can be crushed and miniaturized more efficiently by vibrating the crushing member. Therefore, mist generation efficiency can be further increased.

According to the mist generator of the third aspect, even when the distance between the nozzle and the crushing member is shortened, the liquid ejected from the nozzle can be diffused by the diffusion member and applied to the crushing member. Therefore, the mist generator can be made smaller.

According to the mist generator of the fourth aspect, the liquid crushed by the crushing member is caused to collide with the collision plate,
Since it is possible to further finely reduce the size, mist can be generated more efficiently.

According to the mist generator of the fifth aspect, since the crushing member is constituted by a net, the liquid can be more efficiently mist-formed with a simpler structure.

According to the mist generator of the sixth aspect, since the opening size of the mesh is 0.05 to 2.0 mm,
The liquid ejected from the nozzle can be more efficiently converted into mist.
