Problems solved by technology

However, our experimental analysis results show that if fans are used in a polluted environment, the concentration of dust particles, toxic and harmful gases, viruses and bacteria in the air flow will be several times that of the surrounding environment, which will endanger human health
[0003] In recent years, some people have provided devices that use activated carbon adsorption and filtration and photocatalysts to degrade organic pollutants under ultraviolet light. Such devices are generally only used as special air purifiers with relatively single functions. If the air purification function is applied to purify the airflow of electric fans It can not only improve the practicability of the air purifier, but also reduce the harm of the fan airflow to the human body, which has never been reported in such patent documents
[0004] In the existing air purifiers with photocatalytic purification function, the purification carrier of the photocatalytic layer is generally designed to use airflow guide plate or porous block structure (such as CN98810034.7, etc.) to increase the contact area between catalyst and pollutants, However, the light from such a light source can only irradiate its surface, and the utilization rate is low, which cannot meet the basic requirements of rapid air purification.
[0005] On the other hand, fans and air purifiers in the past are often only designed for applications in a specific environment, and cannot overcome the differences in climate between the north and the south and the four seasons, and the scope of application is narrow

Embodiment Construction

[0033] Such as figure 1 As shown, the embodiment of the present invention adopts the way of back air intake and front air exhaust to circulate air. The power of air circulation comes from the rotation of two coaxial wind blades 6 driven by the motor 14 . The rotation of the first-stage blades on the back generates positive pressure, which pushes the air forward and penetrates the purification layer 12-8; the rotation of the second-stage blades on the front generates negative pressure, which discharges the airflow passing through the purification layer; therefore, the coaxial double-blade structure Increased efficiency of air flow through the purge layer.

[0034] Along with airflow direction, gas first passes through the primary filter layer 15 of the present invention, and primary filter layer is to be made up of double-layer high-strength steel wire 20 clip coarse-pore activated carbon felts 21, as Figure 5 As shown, the primary filter layer 15 can primarily filter out la...

Abstract

Photo-catalytic multifunctional air clean fan comprises by turns initial filter net, first class blade, strong absorption filter layer, humidification layer, catalytic cleaning layer contented light source, active carbon resistant layer, second blade, resistance wire heating layer and shutter-type wind guiding layer. The motor connects and drives with first and second blades, wherein, the former generates positive pressure to push air forward and penetrate all clean layers and the latter is just opposite; besides, the photo-accelerating agent layer uses glass fiber carried accelerating agent to coat the ring light source structure, add cold-air leading cover on front of air inlet. It makes good use of source beam, cleans air flow, kills virus and bacteria in air, fits to north and south and four seasons; the structure is simple and easy to realize.

Description

technical field [0001] The invention relates to a dual-purpose cooling and heating fan with the functions of air purification, humidification and fragrance, in particular to a photocatalyst multifunctional air purification fan. Background technique [0002] Existing fans in the past are generally composed of motors, single fan blades, decorative lights and control circuits, and only have the function of air circulation. However, our experimental analysis results show that if fans are used in a polluted environment, the concentration of dust particles, toxic and harmful gases, viruses and bacteria in the air flow will be several times that of the surrounding environment, which will endanger human health. [0003] In recent years, some people have provided devices that use activated carbon adsorption and filtration and photocatalysts to degrade organic pollutants under ultraviolet light. Such devices are generally only used as special air purifiers with relatively single funct...
