The operation of the pump 15 causes the pressurized chamber 3 to be filled with liquid and circulated. Therefore, the liquid in the pressurizing chamber 3 flows while pulsating or vibrating. at the same time,
The liquid near the nozzle plate 5 also flows and moves. As a result, the local pressurization state of the liquid in the pressurizing chamber 3 due to the vibration of the nozzle plate 5 is disturbed, which has a significant effect such as deterioration of the atomization characteristics (particularly the flow rate, dispersion, etc.).

The rotation of the fan 21 produces a suction effect, thereby filling the pressurizing chamber 3 with liquid from the supply port 7 . At this time, a leveler 9 is required to maintain the positional relationship between the nozzle 4 position and the liquid level in order to maintain the atomization characteristics and function, and also the diameter of the supply port 7 and the path length from the liquid leveler 9. Since the resistance in the path changes depending on the diameter, fan 2
1, it is not easy to set the suction force, and a dedicated fan 21 for filling the pressurizing chamber 3 with liquid is also required.

A pressurizing chamber 3 is provided, and the pressurizing chamber 3
A nozzle plate 5 having one or a plurality of nozzles 4 and an electric vibrator 6 are sequentially mounted substantially concentrically on the holder. Further, a constant liquid level chamber 9 having a supply port 7 and a return port 8 is provided on the other side of the base body 1, separated from the pressurizing chamber 3 by a wall, and the two are communicated with each other through a communication hole 10. and the constant liquid level chamber 9
A pressure regulating hole 11 is provided above the pressure regulating hole 11, and a pressure regulating orifice 12 is provided in the communication hole 10, respectively. The supply port 7 and the liquid tank chamber 13 are connected via a supply pipe 14 and a supply pump 15. The return port 8 is located above the constant liquid level chamber 9, has a slope inside, and is connected to the liquid tank chamber 13 via a return pipe 16.

In the above configuration, gas is first supplied from a gas supply source such as a blower fan (not shown) and passes through the bench lily 19 . At this time, the gas converts a portion of the static pressure into a flow velocity at the throat portion 20, making it much lower than the static pressure on the upstream side. Subsequently, the supply pump 15 is energized to supply the liquid from the liquid tank chamber 13 to the constant liquid level chamber 9, and at the same time, it is also supplied to the pressurizing chamber 3 through the communication hole 10. At this time, the gas whose static pressure has increased before being converted to a flow rate flows into the constant liquid level chamber 9 from the pressure regulating hole 11, pressurizes the liquid level in the constant liquid level chamber 9, and transfers the liquid to the pressurizing chamber 3. At the same time, the ejector effect works by sucking the liquid from the exhaust port 2 of the adjacent base 1 due to the gas whose static pressure has decreased after passing through the throat part 20, and the liquid flows into the pressurizing chamber 3 more quickly. Try to fill with liquid. Then pressurize chamber 3 at a certain height (head).
Continue to maintain the liquid level inside. Blower fan (not shown)
Alternatively, after a certain period of time after the supply pump 15 is energized,
Or after detecting liquid etc. overflowing from the return port 8,
Drive voltage and the like are input from the control section to the electric vibrator 6 through lead wires 17 and 18 in accordance with the amount of atomization.

As a result, the electric vibrator 6 generates expansion and contraction movements in the diametrical direction, and at the same time, the adjacent and attached nozzle plate 5 is excited by bending vibration. Then, the liquid in the pressurizing chamber 3 is locally pressurized, and the liquid is atomized and sprayed from the nozzle 4. During this time, nozzle plate 5
The dissolved gas in the liquid in the pressurizing chamber 3 becomes bubbles due to the cavitation phenomenon due to the ultrasonic vibrations of the bubbles, which are either discharged from the nozzle 4 which is the part of maximum excitation, or coalesce to form large bubbles. It is then discharged to the outside from the exhaust port 2. Therefore, compressible gas (dissolved gas) is always discharged from the pressurizing chamber 3, and the liquid is continuously discharged from the constant liquid level chamber 9 in the same substrate 1 into the pressurizing chamber 3 by suppressing the propagation of pulsations and vibrations. The liquid is supplied as a smooth flow to the liquid, and at the same time is maintained at a constant liquid level. Then, the nozzle plate 5 is maintained in a stable vibrating state, and an atomization device with excellent atomization characteristics and a stable atomization amount variable can be obtained. Also, cooling and heating effects can be obtained by circulating the liquid.

In other words, since the pressure regulating hole is provided in the constant liquid level chamber, the liquid level in the constant liquid level chamber is pressurized at a constant pressure, liquid level fluctuations are suppressed, and a smoother flow is supplied to the pressurizing chamber. A stable atomization device is obtained.
