Abstract

PURPOSE:To uniformize sprayed particles and to increase a spray amount, by fixedly providing an ultrasonic vibrator to an atomizing container and vibrating the container in the direction almost at a right angle to the emitting direction of a liquid. CONSTITUTION:An ultrasonic vibrator 1 is fixedly provided to an atomizing container 2 having a large number of small holes 3 piercing from the inside thereof to the outside thereof and vibration is applied to the container 2 in the direction at a right angle to the emitting direction of a liquid. By this method, small atomizing holes can be made extremely small and a spray amount is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for atomizing liquids such as water and oil. Conventional methods include ■A spray nozzle type that uses liquid pressure to spray water through a simple small hole.■A two-fluid spray nozzle type that uses high-speed air to suck up and spray liquid.■An ultrasonic vibrator is installed at the bottom of the liquid tank to control the liquid level. Ultrasonic type that uses ultrasonic waves to resonate and atomize it. There are also centrifugal types that use centrifugal force to suck up the liquid in the liquid tank and apply it to a rotating disk to atomize it. However,■
Although the amount of atomization is very large, the atomized particle size is large and the variation is large. In addition, although the atomized particle diameter is very small, the amount of atomization is small. Method (2) has the disadvantage that although the atomized particle diameter is small to some extent, the amount of atomization is not so large, the size of the machine is large, and the noise is large.

The present invention overcomes these drawbacks.

The principles and effects of the present invention will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram of the atomization principle according to the present invention.

2 is a container for atomization, which is formed into a cylindrical shape, for example, and has a large number of small holes 3 in its side wall.The size of the small holes varies depending on the type of liquid, and in the case of water, it is about several dozen. Preferably around μ theory. Liquid flows into the container 2 by a liquid pump, an elevated water tank in the case of water, or water pressure. The pressure of the liquid in this case is set by the pressure reducing valve 4 to such an extent that the liquid is discharged in the form of a fountain from a large number of small holes. An ultrasonic vibrator (piezoelectric ceramic) 1 is installed in the container 2 and applies vibration to the container 2 in a direction perpendicular to the liquid discharge direction. In the illustrated example, the vibration is in the left-right direction, but torsional vibration with the left-right direction as the axis may also be used.If a high frequency in the range of several tens of KHz to several MHz is selected as the vibration frequency, the liquid discharged from the small hole disperses as a fine mist. Currently, commercially available ultrasonic humidifiers have a fine spray particle diameter of about 1μ, but the spray at is about 0.51/
However, in the present invention, since countless small holes are provided in the container 2, the dimensions can be made extremely small, and the amount of S to be sprayed can be evaluated to be an order of magnitude larger.

Now, if we assume that the diameter of the small hole is 10μ and the spray velocity from there is 1so/S, then v = 1100 (a/s), A = x /4 (0,0

Figure 2 shows an example of how the humidifier is installed in a duct. The control electrical equipment box 6 has a built-in relay for driving the ultrasonic vibrator 1 and the solenoid valve 5. When humidification is requested, the relay is activated, the solenoid valve 5 is opened, and water pressure is applied to the container 2. At the same time, the ultrasonic vibrator 1 also vibrates at a high frequency, and the container 2 similarly vibrates, and the water discharged from the small holes is atomized by the shear force of this high-frequency vibration.

If water pressure is used, the energy consumption is lower than that of an ultrasonic humidifier since only shear energy is required. In addition, current ultrasonic humidifiers require an aquarium, which limits installation space, and free chlorine for sterilization escapes, causing bacteria in the air to come into contact with the ice surface of the aquarium and breed inside the aquarium. There are some inconveniences.

The device of the present invention can be formed into a thin pipe shape, for example, and can be attached anywhere. Also, there is no risk of spores breeding inside the vibrator.

As described above, the present invention has many advantages and is very effective in practical use.
