Description

[Detailed Description of the Invention] The present invention relates to an ultrasonic spray device that generates mist by imparting vibrational energy to water using an ultrasonic vibrator, and sprays the mist to the outside by forced air blowing by an air blower.

In particular, the present invention uses a cylindrical body that surrounds a water column that rises on the water surface using vibrational energy, blows air into the cylinder through an opening at its lower end, and sends the mist generated by this air through the cylinder to the outside. The purpose of the present invention is to significantly reduce the dripping noise that occurs when water droplets attached to a cylinder drip into a water tank.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a sectional view of an ultrasonic spray device including an embodiment of the present invention, and FIG. 2 is a sectional view of a main part of a cylinder.

In the figure, 1 is a device main body that has a water tank 2 for storing water and a built-in blower 3;
It is fed into the tank 2 from the upper side through the ventilation path 4 by the outer circumferential wall, the water wall, and the bottom wall and side walls of the tank 2.

Reference numeral 5 denotes a cartridge type water supply tank, which is placed on the main body 1 of the apparatus in such a manner that water can always be supplied into the water tank 2, and acts to keep the water level in the water tank 2 constant at all times.

Reference numeral 6 denotes an ultrasonic vibrator attached to the inner bottom surface of the aquarium 2, which imparts vibrational energy to the water in the aquarium 2 when receiving high frequency energy oscillated by an ultrasonic oscillation circuit (not shown). This causes a column of water to rise above the water surface, and from that surface, finer water particles are emitted, in other words, a mist is emitted.

7 is a cylindrical body that penetrates the top plate of the main body 1 of the apparatus and is placed on the top plate, and the lower end is positioned to surround the water column rising above the water surface, and the upper end opening facing the outside has a spray nozzle 8. Form.

Wind from the blower 3 is sent into the cylindrical body 7 through the lower end opening 9, and the sent air is ejected from the spray port 8 along with the mist generated by the rising of the water column.

The inner circumferential wall of the lower end of the cylinder 7 is convex on the inside and the upper surface 10
a, 10 a' are formed substantially horizontally.
．． 10' is provided in a protruding manner and is inserted into the top plate of the apparatus main body 1 so as to be located above the constant water level of the water tank 2.

In such an embodiment, water given vibrational energy by the ultrasonic vibrator 6 produces a water column on the water surface, and the mist generated by this flows into the cylinder body 7 through the ventilation passage 4 and the lower end opening 9. The spray is ejected to the outside from the spray port 8 along with the wind from the blower 3, which contributes to the humidification of the room.

On the other hand, the mist remaining without being ejected to the outside and the large water droplets generated by the rising of the water column adhere to the inner surface of the cylinder 7, and when these adhered water droplets fall into the water tank 2, The upper surface 10 of a plurality of steps 10 and 10' protruding from the inner circumferential wall of the lower end
a, 10a', so the upper surfaces 10a, 10a
Since the falling speed of the water droplets can be significantly reduced by dispersing the water droplets along the water tank 2, it is possible to eliminate the considerable dripping noise that occurs when the water drops fall into the water tank 2.

Incidentally, since the cylindrical body 7 is usually molded with resin, there is no particular problem of increased cost even if the steps 10 and 10' are provided protrudingly.

As explained above, according to the present invention, the inner circumferential wall at the lower end of the cylinder is provided with a plurality of steps in which the inside is convex and the upper surface is approximately horizontal, so that when water droplets attached to the cylinder return to the aquarium, they make a dripping noise. The present invention is extremely useful as a spray device of this type because it does not cause any problem in blowing air into the cylinder, and a cylinder having a simple structure can be used.
