FIG. 2 is a plan view and FIG. 3 is a bottom view of an atomizing liquid tank receiver 3 having a bottom plate 3a , which is an embodiment of the waveguide member .
FIG. 4 is a sectional view taken along line AA in FIG. The atomizing liquid tank receiver 3 has a cylindrical portion 50 in which a notch 52 is formed. The cylindrical portion 50 extends downward, and an annular bottom plate 3a is continuously provided below the cylindrical portion 50. The bottom plate 3a has a circular opening 51 at the center. The bottom of the atomizing liquid tank 4 faces the upper side of the opening 51, and the vibrator 10 faces the lower side. The nebulizing liquid tank 4 is attached to the nebulizing liquid tank receiver 3 by fitting a hook-shaped upper edge of the nebulizing liquid tank 4 into the upper end edge 50a of the cylindrical part 50. The attachment of the atomizing liquid tank receiver 3 to the main body case 1 is performed by engaging the inner surface of the outer peripheral wall 53 extending somewhat downward around the cylindrical portion 50 with the outer surface of the corresponding wall of the main body case 1. Done. In addition, the atomization liquid tank receiver 3 has a hole 54 for air inflow and outflow.

Next, the atomizing action of the inhaler configured as described above will be described. First, a predetermined amount of water is put into the medium liquid tank 7, the atomizing liquid tank receiver 3 to which the atomizing liquid tank 4 is attached is fitted into the main body case 1, and a desired chemical liquid is put into the atomizing liquid tank 4. Then, the upper part of the main body case 1 is covered with the cover 2, and the preparation for atomization is completed. Here, when the power is turned on, the vibrator 10 vibrates with ultrasonic waves, and the ultrasonic waves are transmitted to the water in the medium liquid tank 7.
At this time, the ultrasonic wave is applied to the bottom plate 3 located immediately above the vibrator 10.
The aperture 51 is appropriately narrowed down by the opening 51, and is intensively guided to the bottom of the atomizing liquid tank 4 immediately above the opening 51. The ultrasonic wave transmitted to the bottom of the atomizing liquid tank 4 causes the microvibration of the atomizing liquid tank 4 to be finely vibrated, and the chemical in the atomizing liquid tank 4 is atomized accordingly. Further, the spray is sent from the suction pipe 6 through the spray guide 5 by blowing air generated by the fan motor 20 and the fan 24.

FIG. 6 shows another embodiment of the waveguide member.
The waveguide member shown here can be detachably attached to the main body case 1 by screwing, fitting, or the like, unlike any of the above-described embodiments. Here, a cylindrical member 71 having a circular opening 72 is screwed to a mounting portion of the vibrator 10 of the main body case 1. This tubular member 71
Also, the ultrasonic wave is concentrated on the bottom of the atomizing liquid tank 4 by the opening 72.

[0016]

As described above, in the ultrasonic inhaler of the present invention, the waveguide member is located between the vibrator and the atomizing liquid tank, and the atomizing liquid is sandwiched between the openings of the waveguide member. Since the vibrator is opposed to the center of the bottom of the tank, the ultrasonic waves from the vibrator are narrowed down by the opening and are intensively guided to the bottom of the atomizing liquid tank immediately above the opening. This has the effect of improving the vibration of the tank and improving the atomization efficiency. Therefore, the atomized liquid (chemical liquid) can be used without waste, and there is a benefit in terms of cost for the user.
