Abstract
The utility model discloses a ventilation fan, comprising a housing, a motor installed in the housing and a fan vane installed on the rotary shaft of the motor, the housing is coated with a photocatalyst coating, or photocatalyst is added in the material of the housing, and the photocatalyst coating is coated on the outer surface of the front panel of the housing. Because the housing of the ventilation fan is distributed with the photocatalyst, after the photocatalyst is irradiated by light namely under the irradiation of the ultraviolet light, the photocatalyst generates electron with strong oxidized and deoxidized abilities, the electron generates the action with the oxygen and water of the air contacted with the photocatalyst to generate free radical with strong oxidizing power, then the harmful substances of the air are oxygenized or decomposed and are killed, and the nicotine with bad odour is decomposed so as to effect sterilizing, disinfecting and deodorizing functions; meanwhile, organic substance and greasy dirt are decomposed, the lipophilic substance of the housing of the ventilation fan are changed into hydrotropic substance which can be easily removed by water, so that the ventilation fan is simple and easy to be cleaned.
Description
Technical field
The utility model relates to a kind of ventilation fan, is the ventilation fan of a kind of purification, sterilization, sterilization room air specifically.
Background technology
At present, common ventilation fan only plays discharges indoor air within doors or with the function in the outdoor air suction chamber, the more city of industrial and mining enterprises particularly when the air in the external world is relatively poor, people often close window in case extraneous air enters into indoor, but concentration of carbon dioxide did not obviously increase when indoor air did not circulate for a long time, and people have to again by ventilation fan indoor air be exchanged mutually with outdoor air.For making air in the inlet chamber satisfy people's requirement, people wish that urgently ventilation fan has the function that purifies air, in addition, after ventilation fan uses a period of time, can the many dust greasy dirts of absorption on the housing face-plate of ventilation fan, cleaning is wasted time and energy.
Summary of the invention
The purpose of this utility model provide a kind of have air is carried out sterilization, deodorizing, sterilizing function and can decompose the ventilation fan of greasy dirt in the air.
The utility model is achieved through the following technical solutions.
A kind of ventilation fan comprises shell, motor in the enclosure is installed and is installed in flabellum on the machine shaft, it is characterized in that: be coated with photocatalyst coating or photocatalyst on the described shell and be added in the material of shell.
Described photocatalyst coating is coated on the outer surface of shell front panel.
The utility model compared with prior art has the following advantages.
Owing to be distributed with photocatalyst on the ventilation fan shell, when photocatalyst under i.e. irradiation after the light irradiation at ultraviolet light, dissociate and to have the electronics of extremely strong oxidation and reducing power, the airborne oxygen G﹠W that is in contact with it is had an effect, produce oxidizing force extremely strong free radical, with being about to harmful substances in air oxidation or decomposition, kill harmful substance wherein, and will have the substance decomposition such as nicotine of stink, play sterilization, sterilization, the function of deodorizing, the while decomposing organic matter, impurity such as greasy dirt, make the lipophilicity substance on the ventilation fan shell change hydroaropic substance into, just can easily it be removed by washing, make the work of cleaning ventilation fan become easily simple.
Description of drawings
Fig. 1 is the front view of the utility model ventilation fan;
Fig. 2 is the cutaway view of the utility model ventilation fan;
Fig. 3 is the partial enlarged drawing at A place in the utility model ventilation fan cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model ventilation fan is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, ventilation fan mainly is made up of shell 1, motor and flabellum, flabellum is installed in the rotating shaft of motor, motor is fixedly mounted on the support in the shell 1, the front panel of shell 1 is provided with air inlet 11, air inlet 11 is a plurality of air intake apertures or strip air-inlet grille, adds photocatalyst being coated with on the front panel outer surface of shell 1 in one deck photocatalyst coating 2 or the material at shell.Photocatalyst can carry out sterilization, sterilization and deodorizing to air, can also decompose the dust greasy dirt that is adsorbed on shell 1 front panel.The operation principle of photocatalyst is: photocatalyst inspires the electronics with oxidation and reducing power under the irradiation of ultraviolet light, electronics and airborne oxygen G﹠W generation chemical reaction produce the extremely strong free radical of oxidizing force, free radical is with harmful substances in air oxidation or decomposition, kill harmful substance wherein, and the ammonia and the nicotine that will have stink decompose, impurity such as decomposing organic matter, greasy dirt make the edible vegetable oil material change into the clear water material simultaneously.Just because of photocatalyst has aforesaid characteristic, so when ventilation fan with outdoor air suction chamber in the time, photocatalyst coating 2 on air and shell 1 front panel or fully contact with the shell 1 that contains photocatalyst material, thereby kill harmful substances in air, remove airborne stink substance, make the air in the inlet chamber become pure and fresh, in addition, when dust or greasy dirt are adsorbed onto on the shell of ventilation fan, will soon be resolved into the clear water material by photocatalyst, clean by water and just can remove easily.
Claims (2)
1, a kind of ventilation fan comprises shell, motor in the enclosure is installed and is installed in flabellum on the machine shaft, it is characterized in that: be coated with photocatalyst coating or photocatalyst on the described shell and be added in the material of shell.
2, ventilation fan according to claim 1 is characterized in that: described photocatalyst coating is coated on the outer surface of shell front panel.
