[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an atomizer which vibrates an ultrasonic vibrator to atomize water in an atomizing chamber and discharges the water from a nozzle together with an air flow.

[0002]

2. Description of the Related Art FIG. 8 shows a conventional atomizer, in which an atomizing tank 3 is formed via a diaphragm 4 on an ultrasonic working tank 1 provided with an ultrasonic vibrator 2. The vibration of the vibrator 2 is transmitted to the water in the atomization tank 3 via the water in the ultrasonic action tank 1 to generate mist. The outside air taken in by the fan 5 through the intake port 6 as shown by the arrow A by the fan 5 is guided to the atomization tank 3 from the air duct 6a, the horizontal passage (not shown) and the inflow port 7 as shown by the arrow B. The mist generated in the atomization tank 3 is discharged from the front nozzle 9 through the horizontal passage 8 by this air flow. Nozzle 9 has horizontal axis L
It has a structure in which the tilt can be adjusted to rotate around and the discharge direction of the fog can be adjusted.

[0003]

However, in the above-mentioned conventional atomizer, since the air flow flows into the nozzle 9 from the horizontal passage 8 through the rear end opening 9a of the nozzle, the nozzle 9 is indicated by a virtual line. When the nozzle 9 is tilted as described above, the size (opening area) of the opening 9a at the rear end of the nozzle is reduced, and the discharge amount of the mist from the nozzle 9 is reduced accordingly.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide an atomizer in which the discharge amount does not change even when the nozzle is tilted.

[0005]

In order to achieve the above object, in the atomizer according to the present invention, a horizontal passage extending from the atomization chamber and a horizontal axis crossing the horizontal passage in front of the horizontal passage are provided. An atomizer having a discharge port constituted by a nozzle supported so that tilt adjustment is possible, while closing the rear end of the nozzle corresponding to the discharge port, and protruding to the left and right outside of the nozzle rear end. A pair of rotatably supported pipe-shaped horizontal support shafts are used as inlets for airflow from the horizontal passage, and an airflow flowing from each of the inlets into a central portion between the pair of inlets on the discharge port side. An airflow guide is provided for the airflow.

[0006]

The size (opening area) of the inlet of the pipe-shaped horizontal support shaft at the rear end of the nozzle with respect to the horizontal passage does not change even when the nozzle is tilted, and a constant amount of mist is secured. Since a pair of air flowing into the nozzle from the left and right inlets facing each other is guided to the discharge port of the nozzle by the airflow guide, they do not collide with each other and lose energy.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 7 show an embodiment of the present invention, FIG. 1 is a perspective view of an atomizer, FIG. 2 is a longitudinal sectional view of the atomizer, FIG. 3 is an exploded longitudinal sectional view of the atomizer, FIG. 4 is a cross-sectional view of the atomizer (FIG. 2).
5 is a horizontal sectional view of the atomizer (a sectional view taken along line VV shown in FIG. 2), FIG. 6 is a perspective view around the cooling chamber, and FIG. FIG. 3 is a perspective view of a nozzle.

In these figures, reference numeral 10 denotes an atomizer main body, and reference numeral 40 denotes an upper cover which is assembled and integrated on the upper portion of the main body 10, and as shown in FIG.
It is assembled to the main body 10 by a locking means made of Ob. Reference numeral 11 is formed inside the atomizer body 10,
An atomization chamber in which fog is generated by ultrasonic vibration.
Below, a bottle 20 containing deionized water as an interlocking liquid is connected and integrated. An ultrasonic vibrator 22 is provided at the bottom of the bottle 20, and a thin diaphragm 12 is interposed between the bottle 20 and the atomizing chamber 11 so that the inside of the bottle 20 is sealed. 22
Is transmitted to the water to be atomized in the atomization chamber 11 via the water in the bottle 20. Diaphragm 12
Has a structure in which the connection between the opening of the bottle 20 and the lower end of the atomization chamber forming wall is closely adhered through rubber packing to seal the inside of the bolt 20, so that the water in the bottle 20 is atomized and the water level is lowered. There is no risk of lowering, and there is no hygiene problem that bacteria and the like propagate in the bottle 20.

Above the atomizing chamber 11, a transparent dome 41 assembled and integrated with the upper lid 40 is arranged, and through the transparent dome 41 it is possible to observe the state of generation of mist in the atomizing chamber 11. . Inside the transparent dome 41, a fog diffusion preventing wall 44 extending in a cylindrical shape is formed, and the air flow flowing into the atomization chamber 11 from the air inlet 11a (see FIG. 5) is swirled to form the inside of the atomization chamber 11. Has a structure in which fog does not spread. That is, the air guided through the air duct 37 to be described later and flowing into the atomization chamber 11 from the air supply guide path 42 flows along the outside of the fog diffusion prevention wall 44, and spirally turns into the atomization chamber. The fog in the inside 11 is sent to a horizontal passage 45 in front.

A heater 46 is provided in the horizontal passage 45 in front of the atomization chamber 11, and the fog is heated by the heater 46 and guided to the nozzle 50. As shown in FIG.
As shown in the figure, the partition wall 47 is formed of a pair of partition walls 47, 47 protruding upward in the air sending direction (perpendicular to the plane of FIG. 4). It is formed to have low energy loss and good thermal efficiency. The mist guided forward from the horizontal passage 46 is discharged through a nozzle 50 from a discharge port 50b which is a front open end of the nozzle.

At the rear end of the nozzle 50, as shown in FIGS. 5 and 7, there is formed a pipe-shaped horizontal support shaft 52 extending outward in the left and right directions. It is rotatable by engaging with the arcuate engagement recess 54 on the side. A flange 53 is provided around the horizontal support shaft 52, and a recess 55 is provided around the engagement recess 54 so as to engage with the flange 53. The engagement of these 53 and 54 reduces the area of the engagement portion. Has been enlarged. The nozzle 50 is incorporated in the upper lid 40, and by attaching the upper lid 40 to the atomizer main body 10, the horizontal support shaft 52 is sandwiched by the engaging recess 54 of the atomizer main body 10. 52 can be retained at a predetermined position in the circumferential direction. That is, the degree of inclination of the nozzle 50 (fog discharge direction) can be freely adjusted.

An air inlet 50a from the horizontal passage 45 to the nozzle 50 is formed by a pipe-shaped horizontal support shaft 52 that opens into a semi-cylindrical branched vertical passage 47 rising upward from the horizontal passage 45. The opening area of the air inlet 50a (the opening state of the vertical branch passage 47 of the horizontal support shaft) does not change even if the nozzle 50 is tilted, and a constant flow rate into the nozzle 50 is always ensured. The airflow flowing into the nozzle 50 from the horizontal support shaft 52 is directed to the discharge port 50b by a triangular airflow guide 56 formed in the center of the rear end of the nozzle in the width direction and protruding inward and forward. The airflows flowing in opposite directions from each other do not collide with each other and have a structure with little energy loss.

A cooling chamber 30 surrounding the bottle 20 is formed at the bottom of the container body 10. The cooling chamber 30 is provided with a fan 32 driven by a motor 31,
0 through the air inlet 34 provided on the side wall of the air filter 3.
The bottom of the bottle 20 is cooled by the outside air taken in through the 4a, and the temperature rise of the ultrasonic vibrator 22 and the water in the bottle 20 is suppressed, and the decrease in the atomization efficiency is suppressed. An exhaust chamber 35 is provided inside the cooling chamber 30 and includes a fan 32.
A part of the outside air sent from the air passages 30a and 30b above the cooling chamber to the exhaust chamber 35 is discharged to the lower part of the container body 10 from the exhaust port 35a provided on the bottom surface of the exhaust chamber 35. As shown in FIGS. 4 and 7, a water receiving chamber 38 is formed adjacent to the cooling chamber 30 and has an opening 37a of a blow duct 37 extending straight upward.
Numeral 8 is separated from the cooling chamber 30 by a waterproof plate 39a (see FIGS. 2, 4 and 7), and a water receiving chamber 38 is provided with a drain hole 39b.
8 can be drained. That is, in a state where the upper lid 40 is removed, the upper opening 37b of the air duct 37 is provided adjacent to the atomizing chamber 11, and when the atomizing water is injected into the atomizing chamber 11, the water is erroneously inserted into the air duct 37. There are cases. A motor 31 for driving a fan 32 is accommodated in the cooling chamber 30, and a printed wiring board B and other electrical components are accommodated and arranged near the cooling chamber 30. This is not preferable because it may lead to the occurrence of a failure or a failure. However, in the present embodiment, the water that has entered the water receiving chamber 38 is retained in the water receiving chamber 37 by the waterproof plate 39a, and cannot enter the area other than the water receiving chamber 37, for example, the cooling chamber 30. It is structured to be discharged outside.

The outside air that has passed through the air duct 37 above the water receiving chamber 37 is guided to the atomizing chamber 11 via an air feeding guide path 42 formed on the side of the atomizing chamber 11.

[0015]

As is apparent from the above description, according to the atomizer according to the present invention, the size (opening area) of the inflow port of the pipe-shaped horizontal support shaft at the rear end of the nozzle with respect to the horizontal passage is equal to that of the nozzle. Even if the nozzle is tilted, it does not change, and a constant mist discharge amount is secured, so that an atomizer in which the discharge amount does not change even when the nozzle is tilted can be obtained.

Further, a pair of air flowing into the nozzle from the left and right inlets facing each other is guided to the discharge port of the nozzle by the airflow guide, so that they do not collide with each other and lose energy. An atomizer with high efficiency is obtained.
