Description

Ultraviolet LED air sterilization purifier

Technical Field

The utility model relates to an air sterilization purifies technical field, especially relates to an ultraviolet LED air sterilization purifier for interior space.

Background

At present, the technical field of air sterilization and purification of indoor space is generally carried out by using mercury lamp ultraviolet lamp tubes or instruments and equipment adopting an ozone generation technology. Because of the harmfulness of ultraviolet rays to human bodies and the irritation of ozone to the respiratory tracts of the human bodies, people who need to empty the field usually can not sterilize and disinfect the air at any time and any place during sterilization operation. In addition, as the mercury lamp contains harmful metal mercury, the subsequent recovery treatment needs to consume a large amount of resources, and has great potential threat to the environment, China signs and joins the water guarantee about mercury in 2013 to agree with the state of contracting of the public convention in China, the public convention in 2017 formally takes effect in China, and the public convention in 2020 will gradually and comprehensively forbid the production and use of products containing mercury. The mercury lamp tube usually adopts a direct irradiation method for air sterilization, and if no additional air circulation device is added, a dead zone of ultraviolet irradiation is easily caused by shielding of objects in the sterilization space, which is also one of the reasons that the ultraviolet lamp tube has poor sterilization effect.

In recent years, ultraviolet LED (light emitting diode) light emitting technology of UVC (ultraviolet light emitting diode) waveband is mature day by day, people are rapidly attracted attention due to the extremely small size, no harmful elements are generated and pure sterilization waveband, the ultraviolet LED light emitting technology is applied to the field of air sterilization only, and direct sterilization of air is carried out by using a direct irradiation mode of an ultraviolet lamp tube of a mercury lamp. However, due to the technical limitation of the ultraviolet LED lamp at present, the cost of the ultraviolet LED lamp is high, and compared with a mercury lamp, the ultraviolet LED single body has relatively low luminous power, so that the sterilization effect is poor, and the large-scale application of the ultraviolet LED in the air sterilization field is limited.
