Abstract

PURPOSE: To accurately and easily feed a liquid to the central part of the maximum amplitude of vibration and to dissolve defects in a complicated constitution of liquid feeding by the conventional nozzle, by installing a narrow pipe or the like for guiding the liquid to the central region of the tip part of a vibration body of an ultrasonic vibration transducer atomizing means from a stop valve. CONSTITUTION: In an atomizer body case 1, a liquid container 2 housing a liquid perfume 3 and a valve driving part 7 for a stop valve 8 are arranged. The liquid perfume 3 is dropped by gravity into a narrow pipe 9 opened and closed by the stop valve 8 and discharged to a vibration body 14 of an ultrasonic vibrator transducer atomizing means 13 from a discharge hole 9a of the narrow pipe 9. In such a mechanical constitution, it is easy that the discharge hole 9a of the narrow pipe 9 is accurately positioned at the center of the vibration body 14, and the position adjustment thereof is performed in a short time. After that, the atomized perfume particles are passed through a filter 15 and diffused to the outside from a vent hole 17 together with air taken in by a fan 16.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an atomizing device suitable for use as, for example, an aroma device for diffusing a trace amount of fragrance into the atmosphere.

[0002]

2. Description of the Related Art Conventionally, as a device for releasing a fragrance or the like, a solid fragrance is naturally volatilized to be atomized,
Alternatively, an atomizing device is used that atomizes a small amount of liquid fragrance sucked up by a pump into an atomized state by an ultrasonic vibrator. As a device for atomizing perfume into a room such as a hotel lobby or a showroom in a relatively large place to perfume the scent, there is a device that blows out a fragrance that a solid perfume stored in a perfume tank vaporizes and volatilizes naturally. However, it was difficult to supply the optimum concentration of fragrance in the case of natural evaporation of fragrance. Therefore, there is known a perfume atomizing device that atomizes a liquid perfume by vibration of an ultrasonic transducer and blows the atomized perfume particles by a blower. This atomizer of fragrance uses a fragrance supply pump with a timer to supply the fragrance consisting of liquid to the tip of the ultrasonic vibrator, and from this pump through the fragrance supply pipe, A structure was used in which a nozzle was placed at the position of maximum vibration amplitude with good atomization efficiency to discharge the fragrance.

[0003]

However, in the above-mentioned conventional atomizer for perfume, the nozzle is accurately arranged at the center of the maximum vibration amplitude position of the tip of the ultrasonic vibrator so as not to be displaced by vibration. In order to supply a certain amount of fragrance to that position for a predetermined time, a timer-controlled fragrance supply pump is used, and the configuration of the device becomes complicated,
There was a drawback that the case became large and expensive. Also, there is a problem that the perfume supply pipe from the perfume supply pump is clogged and smooth supply cannot be performed, so that the perfume supply pump must be cleaned regularly.
Further, even when the fragrance is replaced, the fragrance container and the pipe of the pump must be cleaned, which is complicated.

The present invention has been made in order to solve such a problem, and has a structure in which a liquid can be accurately and easily supplied to the central portion of the maximum vibration amplitude of an ultrasonic vibrator, and a conventional nozzle is used. Eliminates the disadvantages of the complicated configuration of liquid supply due to, and can diffuse a small amount of perfume efficiently into the atmosphere efficiently without using an expensive and space-consuming pump, and facilitate perfume exchange and cleaning. An object is to provide a compact atomizing device.

An ultrasonic transducer atomizing means disposed below the nozzle for atomizing the liquid; a thin tube for guiding the liquid from the opening / closing valve to the central region of the tip of the oscillator of the ultrasonic transducer atomizing means; And a blower that blows the atomized particles in a predetermined direction.

Further, the atomizing device according to the present invention comprises a compressor for feeding air into the liquid container from above, and a control means for opening the on-off valve and operating the compressor to pressurize the liquid in the liquid container. It is characterized by that.

[0007]

In the atomizing device of the present invention, the liquid in the liquid container is guided to the central region of the tip portion of the vibrating body of the ultrasonic vibrator atomizing means through the opening / closing valve by the thin tube, The liquid introduced onto the vibrating body of the ultrasonic vibrator atomizing means is atomized with high atomization efficiency by ultrasonic vibration, and is efficiently diffused into the atmosphere by the air blowing means without waste.

Further, in the atomizing device according to the present invention, the liquid in the liquid container is pressurized by the compressor to open the opening / closing valve, and the ultrasonic vibrator atomizing means moves to the central region of the tip portion of the vibrating body having the largest vibration amplitude. The liquid is guided, and the liquid guided onto the vibrating body of the ultrasonic vibrator atomizing means is atomized by ultrasonic vibration, and is efficiently diffused into the atmosphere by the blowing means without waste.
