Description

Air purification and sterilization dual-purpose device

This creation is about an air purification and sterilization device.

Hand-held UV lamps, such as the Republic of China new patents M284393, M397829 or, for example, the sterilizing rods disclosed in the commercially available mites, can use ultraviolet light to sterilize various items such as sheets, pillows, sofas, toys, etc. The chemical and odorless benefits of using a safety switch, etc., make the UV lamp only illuminate at a certain angle, for example, only when it is facing down, to prevent the user's eyes from looking directly at the UV rays.

In addition, various odors, dusts, and the like are present in the air, and the use of photocatalysts to purify the air can quickly and effectively improve the indoor air quality and provide a healthy living environment free from pollution and bacteria. Under the action of ultraviolet light, the photocatalyst shifts electrons (e) on the valence band to the conduction band, and generates corresponding holes (h+) on the valence band to generate superoxide ion radicals and hydroxyl radicals with extremely strong oxidation. Superoxy hydroxyl radicals can not only oxidize and decompose toxic and harmful gases such as formaldehyde, benzene, toluene, xylene, ammonia, TVOC, etc., pollutants, odors, bacteria, etc. into harmless CO ₂ and H ₂ O, The pathogenic bacteria have a good inhibition and killing effect, so the photocatalyst material, the ultraviolet lamp and the filtering system can be combined to effectively achieve the effect of the photocatalyst to purify the air.

Etc., when placed on the charging stand, the ambient air purification can be performed by the photocatalyst in the device.

Furthermore, one of the purposes of this creation is to provide a water-to-air purification and sterilization device that can effectively achieve air purification regardless of the humidity in the environment.

In order to achieve the above object, according to an embodiment of the present invention, an air purifying and sterilizing device is disclosed, comprising: a hand-held rod body including a casing and an ultraviolet illuminating window disposed on one side surface of the casing; The module is disposed in the casing of the hand-held bar body, and the light emitted from the ultraviolet module is emitted from the hand-held bar through the ultraviolet irradiation window; the plurality of glass beads are disposed in the casing of the hand-held bar body Surrounding the ultraviolet module, a part of the light emitted from the ultraviolet module can be received, but the light emitted from the ultraviolet module is not shielded from the surface of the hand-held bar through the ultraviolet irradiation window, and the surface of the plurality of glass beads a battery unit, disposed on the hand-held rod body, electrically connected to the ultraviolet module, having a charging socket for connecting an external power source; a rod fan disposed on the hand-held a rod body for circulating air inside and outside the hand-held rod; the charging base having an electrical connection with a charging socket of the battery unit of the hand-held rod And a plug connector may be connected to the external power source, the charging cradle and the handset is provided with a bar separating member but may be held by hand with the rod The rod body is combined and seated on the charging base.
