Preferably, the axial projection of each blade 71 forms a 180 ° fan-shaped projection, so that the overall flow efficiency of the spiral duct is higher, and the wind pressure, flow rate and noise are improved obviously.

Alternatively, the water mist head 63 comprises a shell assembly, an ultrasonic atomization sheet and an electrode assembly. The shell assembly comprises a front shell, a middle shell and a rear shell which are sequentially connected along the fluid flowing direction, the front shell, the middle shell and the rear shell jointly form a fluid channel in the axial direction, a port on the side of the front shell is used as a water inlet, a port on the side of the rear shell is used as a mist outlet, and the water inlet and the mist outlet are communicated with the fluid channel so that fluid enters from the water inlet and flows through the fluid channel and then flows out from the mist outlet; the ultrasonic atomization sheet is arranged in a fluid channel between the front shell and the middle shell and is used for atomizing an entering fluid to form water mist; an electrode assembly is disposed in the fluid passageway between the center housing and the rear housing for applying an electrical charge to the passing water mist to form an electrically charged water mist.

Specifically, the front shell, the middle shell and the rear shell are all provided with through holes in the flowing direction of fluid, namely the front shell, the middle shell and the rear shell are all annular parts with the through holes, and after the front shell, the middle shell and the rear shell are sequentially connected, the through holes in the front shell, the through holes in the middle shell and the through holes in the rear shell are communicated, so that a fluid channel is jointly constructed. The fluid may be pure water, tap water, etc., and flavoring agent, freshener, etc. may also be added into the fluid. It is understood that the fluid is not limited to water.

Fluid gets into the fluid passage of shell subassembly from the water inlet in, is atomized and forms water smoke when the ultrasonic atomization piece, and water smoke is exerted electric charge formation lotus electric water smoke when passing through electrode subassembly, and the back is spouted from the fog outlet to lotus electric water smoke, can carry out the humidification to the room air on the one hand, and on the other hand can adsorb pollutants such as particulate matter in the air, realizes the purification to the air.

The flow and treatment of the fluid in the water mist head 63 is as follows: the water mist enters the fluid channel through the water inlet of the front shell, then forms water mist through the atomization effect of the ultrasonic atomization sheet, the water mist flows through the middle shell, then is charged through the electrode assembly to form charged water mist, and the charged water mist passes through the rear shell and finally flows out of the mist outlet in the rear shell.

The shell component fixes the ultrasonic atomization sheet and the electrode component in a space where fluid flows through the arrangement mode of the front shell, the middle shell and the rear shell, and the ultrasonic atomization sheet and the electrode component are sequentially arranged along the flowing direction of the fluid, so that the process of atomizing water flow firstly and then charging is realized, and finally, charged water mist is formed.

The ultrasonic atomization piece is provided with a positive terminal and a negative terminal, and can utilize electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz and exceeds the hearing range of people, and the electronic oscillation has no harm to human bodies and animals) after the ultrasonic atomization piece is connected with a circuit through the positive terminal and the negative terminal, and break up a liquid water molecule structure through the high-frequency resonance of the ceramic atomization piece to generate naturally elegant water mist.

The electrode assembly is capable of generating an electric field and the water mist is capable of carrying an electric charge when passing through the electrode assembly. The charged water mist has charges on the surfaces of the fog drops, and can adsorb suspended particles in the air, such as PM2.5, pollen, dust, catkins and the like, so that the air is purified. Furthermore, by adjusting the amount of spray, the radius of the electrode assembly, and the voltage applied to the electrode assembly, the droplets can be further ionized to form hydrogen ion and hydroxyl radical plasma, which can kill viruses and bacteria in the air. In addition, because formaldehyde is dissolved in water, the air entering the humidifying device is humidified in an atomizing mode, the contact area of the formaldehyde and the water can be increased, and the formaldehyde is soluble in the water, so that the formaldehyde removing device also has a certain effect on removing the formaldehyde in the air.

Optionally, the electrode assembly is connected to a negative high voltage power supply. Thus, the electrode assembly can form a strong electric field. The ultrasonic atomization sheet is connected with a grounding wire, and specifically, the grounding wire is connected with a negative binding post of the ultrasonic atomization sheet; when micron-sized water mist generated by the ultrasonic atomizing sheet passes through an electric field generated by the electrode assembly, negative charges in the mist droplets are repelled based on the same polarity repelling effect, and the negative charges run off along a grounding wire and are retained through the conduction effect of the water mist because the water mist is dispersed in a fluid passage between the electrode assembly and the ultrasonic atomizing sheet, so that positive charges are carried by air flow jetted by the water mist nozzle 63.

Optionally, the electrode assembly comprises a first electrode and a second electrode. The first electrode is annular, so that the water mist passes through the area surrounded by the first electrode and charges with a first charge amount are applied to the water mist; the second electrode is annular, has a diameter larger than that of the first electrode, and is arranged adjacent to the first electrode in the flowing direction of the fluid, so that the water mist passes through the area surrounded by the second electrode and charges with a second electric charge quantity are applied to the water mist; and the first amount of charge is greater than the second amount of charge.

The water mist can be acted by the electric field when passing through the first electrode or the second electrode. As is well known, the smaller the radius of the electrode, the stronger the electric field intensity generated, and the larger the diameter of the second electrode is than that of the first electrode, so the electric field intensity generated by the first electrode is larger than that generated by the second electrode; the amount of electric charge applied to the mist when passing through the first electrode is larger than the amount of electric charge applied to the mist when passing through the second electrode. Thus, the electric charge quantity applied to the water mist by the electrode can be adjusted by controlling the first electrode and the second electrode to be switched to be electrified. When the amount of electric charge carried by the water mist is different, the purifying effect on the air is also different.

When the radius of the first electrode is smaller or the applied voltage is higher, the electric field generated by the first electrode is stronger, the stronger electric field ionizes the water mist to generate hydrogen ions, hydroxyl radicals or active oxygen ions, and the hydroxyl radicals and the active oxygen ions have strong oxidation effect and can damage cell membranes on the surfaces of bacteria, so that the sterilization effect is achieved; when the radius of the second electrode is larger or the applied voltage is smaller, the electric field generated by the second electrode is weaker, the weak electric field cannot ionize the water mist, the water mist is not electrified integrally, but the weak electric field can enable the electric charges on the surface of the water mist to be classified and gathered, and therefore dust can be adsorbed. It will be appreciated that in some cases, when the electric field generated by the second electrode is increased to a certain extent, water molecules in the water mist will be ionized.
