Abstract
Description
本發明係與殺菌器有關,特別是一種紫外光光觸媒殺菌器。The present invention is related to sterilizers, especially an ultraviolet light photocatalyst sterilizer.
紫外線具有良好的殺菌消毒作用,且紫外線消毒燈目前已被廣泛的運用,是傳染性病毒消毒殺菌的最好方法,而光觸媒(photocataylst)是一種利用光能進行催化反應的觸媒,使用前會先把光觸媒塗布或噴灑在物體表面形成一層薄膜,在透過光能啟動與附在物體表面的外來物質產生氧化或還原作用,以達到除汙、殺菌、抑菌或使物體表面清潔的目的。Ultraviolet light has a good sterilization and disinfection effect, and ultraviolet disinfection lamps have been widely used at present. It is the best method for disinfection and sterilization of infectious viruses. Photocataylst is a catalyst that uses light energy to carry out a catalytic reaction. First, the photocatalyst is coated or sprayed on the surface of the object to form a thin film, which can activate the oxidation or reduction of the foreign substances attached to the surface of the object through the light energy, so as to achieve the purpose of decontamination, sterilization, antibacterial or clean the surface of the object.
常見的紫外線與光觸媒的結合方式如台灣TWI511768B號發明公告專利案描述一種過濾模組,將光觸媒材料包覆於金屬網後,提高紫外線有效照射於光觸媒的面積,提高過濾效果。然而在此配置中,鋸齒狀突出或弧狀突出的金屬網會使得紫外光線所散發的能源無法被有效的利用。A common combination of ultraviolet rays and photocatalysts, such as Taiwan TWI511768B Invention Announcement Patent Case, describes a filter module that covers the photocatalyst material on a metal mesh to increase the area where the ultraviolet rays are effectively irradiated on the photocatalyst and improve the filtering effect. However, in this configuration, the zigzag or arc-shaped metal mesh will make the energy emitted by the ultraviolet light unable to be effectively used.
