Relates to an ultrasonic humidifier.

In general, the humidifier is installed in the home or office indoors to supply moisture to the air. Types of humidifiers include centrifugal spraying, which blows and blows inhaled water with centrifugal force to granulate it, and generates an electric signal of a frequency set in an electric circuit and transmits it to a vibrator in water to generate ultrasonic waves. And ultrasonic humidifiers that generate a thin mist due to the vibration phenomenon of the back, and an electrothermal humidifier that generates steam by heating water for a heater or an electrode.

In detail, the ultrasonic humidifier has a structure in which atomized particles penetrate water of 25 to 45 mm in depth, and ultrasonic waves generated by vibrating a piezoelectric vibrator with a 1.65 MHz to 2.45 MHz oscillator at an AC 48V voltage in a liquid. Radiating to the surface of the liquid causes the water in contact with the piezoelectric vibrator to resonate, increase in amplitude, and splash the droplets and droplets, causing the atomized particles to come out of the water.

However, the ultrasonic humidifier of such a structure has the following problems. First, since the atomized particles have to penetrate through the water, the atomized particles become larger and the rate of divergence at the surface decreases, causing condensation and dropping immediately after atomization. There was a problem that the noise generated by splashing water droplets. Second, as the splash and noise is generated, not only unnecessary energy is consumed, but also a separate blower is necessary to dissipate atomized particles into the air, thereby causing a complicated structure.

 In order to solve the above problems, the present invention not only reduces noise and power consumption caused by spraying water, but also places a microplate attached to the piezoelectric vibrator on the surface of water to remove the blower, and passes through the microplate. It is an object of the present invention to provide a buoy type ultrasonic humidifier using a microplate to allow the atomized particles to be emitted immediately into the air without passing through the water.

In order to achieve the above object, the ultrasonic humidifier of the buoy method using a micro-plate according to the present invention, the power switch on / off; A first bucket through which water is received; A lower limit level sensor for sensing a lower limit level of the first bucket; A pump for transporting water contained in the first bucket; A second water container containing water transported through the pump and having a support formed therein; A reference level sensor for detecting a reference level of the second bucket; It is installed so as to be rotatable on the support formed in the second bucket, the piezoelectric vibrator, the injection module having a micro-plate attached to one end of the piezoelectric vibrator and a plurality of fine holes formed and buoyancy member installed to act on the micro-plate ; When the switch is operated and the power is turned on, it generates a set frequency and transmits the set frequency to the piezoelectric vibrator of the injection module and applies the power to the piezoelectric vibrator. Controlling to generate atomized particles from the water, if the reference level sensor detects the reference level of the second bucket, the pump is operated to control the water in the first bucket is transported to the second bucket, the lower level detection When the sensor detects the low water level of the first bucket, it characterized in that the control module for stopping the generation of the set frequency and cut off the power to the piezoelectric vibrator.

Here, the reference water level sensor may be installed at a position where at least a part of the injection module microplate is submerged in water or the microplate is in contact with the water surface to generate a surface tension between the water and the microplate.

In addition, the first bucket, the second bucket and the injection module is preferably installed to be detachable, respectively attached to facilitate the cleaning and maintenance.

The ultrasonic humidifier may further include a display lamp for displaying a state of the water level of the first bucket and an operation state of the injection module so that a user may check the state of the humidifier.

In addition, the first bucket 120 may open and close the upper portion using a predetermined lid 122.

The second bucket 130 has a predetermined space formed therein to accommodate water, and a support 131 having a hinge groove 131a is formed at a predetermined position so that the injection module 140 can be installed. The sensor 132 is installed to detect the reference level of the water received in the open form. In addition, the second bucket 130 uses a predetermined injection guide tube 133 formed with a guide hole for protecting the installed injection module 140 and guiding atomized particles injected from the injection module 140 in a desired direction. The top can be opened and closed. At this time, the first bucket 120 and the second bucket 130 may be installed to be detachable from the main body 110 to facilitate the cleaning and maintenance.

The injection module 140 includes a hinge pin portion 144a that can be inserted into the hinge groove portion 131a of the support 131 formed in the second bucket 130 so that the rotation of the injection module 140 is freely performed as the water level is changed. It is installed with a hinge structure to make it possible. The injection module 140 is fixed to the piezoelectric vibrator 141, the piezoelectric vibrator 141 for generating ultrasonic waves by receiving a predetermined frequency, so that the ultrasonic wave generated in the piezoelectric vibrator 141 is not attenuated inside The micro-plate 143 is attached to one end of the fixing member 142, the piezoelectric vibrator 141 and formed with a plurality of fine holes to vibrate in accordance with the ultrasonic generation of the piezoelectric vibrator 141 to spray atomized particles into the air.
