Abstract

The utility model relates to a fan structure. Wherein, a lamp tube is mounted on a fan body. The lamp tube can give out light in certain wave length. On the lamp tube, a filter screen is mounted. On the filter screen, a light catalyst is coated. At front of the filter screen, vanes coated with the light catalyst are provided. When the fan is started, the vanes rotate and drive air to enter from back of the fan, and exhaust from front of the fan; meanwhile, the lamp tube gives out light in certain wave length to illuminate the filter screen and the light catalyst of the vanes, which can deodorize and suppress bacteria. With combined function from the filter screen and the vanes, odd odor and viruses in air can be filtered efficiently. In addition, the setting of the filter screen allows any dust and fiber in air to attach to the filter screen, so as to maintain the operation of the fan.

Description

Fan structure

Technical field

The utility model is relevant for a kind of fan structure, refers to the fan structure of the pollutant such as peculiar smell, bacterium, dust, impurity in a kind of effectively filtered air especially.

Background technique

Because of lifestyle due to the industrial and commercial society changes, people's most time is all treated indoor, and the interior space is comparatively airtight, cause indoor air often to be in dirty carrier state, contained Formalin in the Ruo Jiazhu building materials, volatilization gas in toluene or the coating etc., long term exposure is at environment like this, easily cause the discomfort of health, in view of this, the dealer is that daylighting catalyst technology is to subdue harmful substances in air, common person is in product coating photo catalysis, this photo catalysis promptly is with the light source of sunlight or the specific wavelength energy source as chemical reaction, and utilize titanium dioxide (TiO2) as the catalyst catalytic materials, quicken the redox reaction of material in the atmosphere, oxygen around making and water molecule are excited into the splendid free radicals of oxidizing force to decompose human body or harmful organic substance and the part inorganic substances of environment, make astable and the rapid oxidation Decomposition of harmful matter restores and is combined into stable and innoxious substance, with the filtration, purification air, so generally have the fan of filtering function, be fluorescent tube to be set in fan body, this fluorescent tube can send the light source of the following wavelength of 400nm, and the blade surface application titanium dioxide (TiO2) of fan, the light that this titanium dioxide (TiO2) is sent by fluorescent tube shines and produces photocatalyst reaction, blows out the air of cleaning via fan; So, this general fan that filters is only in blade application titanium dioxide, and the dust that is scattered in the air, smog, peculiar smell, dirt mite, bacterium and other virus etc., all can be attached on the blade and cover the titanium dioxide of this blade institute application, and the filtering effect of this fan that detracts, again in the fan running process, impurity such as dust in air, cotton-wool and fiber fines also can adhere to and accumulate on its place of blade and fan, as the axle center etc., and reduce the operational effectiveness of fan.

Summary of the invention

The utility model main purpose provides a kind of fan structure, be in fan body installing fluorescent tube, this fluorescent tube can send the light source of specific wavelength, continue and filter screen is set at the fluorescent tube place, application photo catalysis on this filter screen, the blade of coating photo catalysis is set in this filter screen the place ahead again, when starting fan, the light source that this fluorescent tube sends specific wavelength shines photo catalysis in filter screen and blade to produce photocatalyst reaction, discharge by fan the place ahead again after blade rotation makes air be entered by the fan rear simultaneously, so dirt mite of being scattered in this air, smog, peculiar smell, bacterium and other virus etc. promptly can be adsorbed in filter screen, and after filter screen is filtered only in advance, this air continues and flows to the capable again filter in blade place only, in view of the above, it is peace and quiet making the air of discharging via this fan, odorless, virus-free, and also can make dust in air by the setting of this filter screen, cotton-wool, impurity such as bacterium and fiber is attached to this filter screen, to keep the operational effectiveness of this fan.

Embodiment

At first, see also Fig. 1, shown in Figure 2, filtration fan structure of the present utility model, it is installing fluorescent tube 2 on the back protecting wire net that fan body 1 and preceding protecting wire net mutually combine, this fluorescent tube 2 can send the specific wavelength light source of 365nm, continue and filter screen 3 is set at the place, front side of fluorescent tube 2, the material of this filter screen 3 can be adopted the synthetic fiber cloth of good air permeability, and in these filter screen 3 application photo catalysiss 4, this photo catalysis 4 can be titanium dioxide (TiO2), establish tool blade 5 in filter screen 3 the place aheads again, also be coated with photo catalysis 4 in blade 5 surfaces.

See also shown in Figure 3, when in starting fan, fluorescent tube promptly can send the ultraviolet of 365nm to excite the photo catalysis 4 of filter screen 3 and 5 applications of blade, cause photocatalyst reaction, produce antibacterial, filtrations such as deodorization, in this simultaneously, blade 5 revolutions drive is discharged by fan body 1 the place ahead after air is entered by fan body 1 rear again, the dirt mite of in air, being scattered, smog, peculiar smell, bacterium and other virus promptly are adsorbed in filter screen 3 also earlier after filter screen 3 is done filter only in advance, continue this air again row flow to blade 5 places to do other time filter clean, the clean effect of common in view of the above filter, it is aseptic making the air of discharging via this fan, odorless, virus-free peace and quiet air; Moreover impurity such as the also adsorbable dust in air of the setting of this filter screen 3, cotton-wool, fiber fines make its place of the blade 5 of this fan and fan, as: axle center etc., unlikely being subjected to adhering to of these impurity is to keep good operational effectiveness.

Such as above-mentioned structure, the following advantage of the true tool of the utility model as can be known:

1. the set filter screen of the utility model, it is the coating photocatalyst, causes this filter screen and sent by fluorescent tube The effect of specific wavelength light source can produce the photocatalyst effect of the functions such as tool is antibacterial, deodorization, and with application light The blade of catalyst cooperates jointly, with the dirt mite in effective filtered air, peculiar smell, bacterium, virus etc., and prevention Many diseases such as asthma, bronchitis provide odorless, aseptic pure and fresh environment.

2. the set filter screen of the utility model, be located at the blade rear, air is entered by the fan rear when fan rotates, discharge by fan the place ahead again, so impurity such as dust in air, cotton-wool, fiber fines can be adsorbed in filter screen in advance, can significantly reduce all this impurity in view of the above and be attached to its place of blade and fan, as: axle center etc., the good operational effectiveness of this fan is kept in order.

Claims (3)

1. fan structure is characterized in that: in fan body installing fluorescent tube, continuing is provided with filter screen at the fluorescent tube place, in this filter screen application photo catalysis, the blade of coating photo catalysis is set in this filter screen the place ahead again.

2. fan structure as claimed in claim 1 is characterized in that: the material of this filter screen can be the synthetic fiber cloth.

3. fan structure as claimed in claim 1 is characterized in that: this photo catalysis can be titanium dioxide.
