The nano water ion module 9 includes a plurality of porous release needles with nano pores, and the porous release needles are connected to the high-voltage electrode. When the air passes through the nano water ion module 9, the water in the air is released by the porous release needles with nano pores. Absorption, thereby being differentiated into nano-scale water, and then into highly active charged nano-scale charged water particles under high-voltage excitation. The porous release needle uses a ceramic with high specific surface area as the inner core, and is wrapped with a high-porosity hydrophilic fiber material, and adds nano-platinum, which can efficiently absorb the water in the air and keep the water inside through the capillary principle. , under high-voltage excitation, nano-charged water particles with a diameter of 1-50 nm are released.

The advantages of the above settings are:

By setting the nanometer water ion module 9, the air coming out of the fan 2 is in full contact with the nanoscale charged water particles generated by the nanometer water ion module 9 installed at both ends of the air outlet 12, and through the periodical swing of the swing blade 8, the charged water particles The air flow is well mixed and enters the room with the air flow, actively capturing and purifying bacteria from the indoor air and all surfaces. The charged water particles have very high activity, can effectively antibacterial and deodorize, and the water particles are effective for a long time. In addition, the ionized hydroxyl radical (·OH)-based advanced oxidant can effectively decompose formaldehyde gas and odor pollution sources in the environment, and form CO2 and H2O without secondary pollution. When the charged water particles come into contact with the bacteria, they can destroy the bacteria's proteins and DNA, thereby killing the bacteria. Nanometer water particles are continuously released by the nanocharged particle generator, reaching every corner, effectively inhibiting the growth of bacteria in the air. For common bacteria such as Escherichia coli, Staphylococcus aureus and alba. In addition, the material of the nano water ion module 9 has no loss and no secondary pollutants, and the nano-scale charged water particles can exist in the air for a long time, and the user does not need to worry about the reduction of the sterilization effect due to time. In the breeze mode, through the action of the swing blade 8 and the wind deflector 7, the nano-charged water particles and hydroxyl radicals ( OH) can be more evenly mixed into the air flow, which completely realizes the air supply, sterilization and odor removal of the air conditioner. In the non-breezy mode and the operating wind speed of the fan 2 is high, even if the uniform mixing of nano-scale charged water particles and air cannot be achieved in the air conditioner, the charged water particles can be effectively discharged into the room to sterilize the indoor air. Purify.

By arranging the two nano water ion modules 9 on the two inner side walls of the air outlet 12 respectively, and one is arranged at the top of the inner side wall and the other is arranged at the bottom of the inner side wall, the connection between the nano water ion module 9 and the air flow can be improved. Contact area to improve the mixing effect of charged water particles and air flow.

The wind speed can realize the breeze supply, achieve the effect of cool but not cold, warm but not hot, and improve the somatosensory comfort of the human body. Since the natural wind is generally softer after decelerating through the shaded leaves, the swing leaf 8 is biomimetic to the shape of the natural leaves, and the swing rod drives the motor to drive the left and right swing, so that the wind from the volute is closer to the natural wind under the action of the swing leaf 8 , the wind adjusted left and right through the swing blade 8 is then adjusted up and down through the wind deflector 7, so that the wind blown by the air conditioner is more gentle. The cross-sectional areas of the first micro-hole 71 and the second micro-hole 81 diverge outward from the middle to both ends, which is not only conducive to the mold release of the structural process, but also can be diverged outward by the wind of the micro-porous structure, so that the first micro-hole 71 and the /or the wind directions of the second micro-holes 81 are different, and are closer to the natural wind.

The arrangement of the first transverse reinforcement rib 52 and the second transverse reinforcement rib 72 improves the overall strength of the panel body 5, and the first transverse reinforcement rib 52 and the second transverse reinforcement rib 72 are arranged in a strip shape, so that the entire strip-shaped panel The main body 5 has simple lines, which optimizes the structure of the panel main body 5 .
