Description
Technical field:
Originally practical to be related to air purifier, and in particular to a kind of photocatalysis air purifying device with self-purification capacity.
Background technique:
At nearest several years, the gradual visual field for entering people, reason were the exposure of haze pollution to air purifier.Respectively
Air cleaning manufacturer is proposed the air purifier of many types, but all similar.Universal, air purifier includes
The filter screen that particle can be filtered generally includes two layers of filtration system of low efficient filter screen and high efficiency particulate air, to stop air
In dust particle such as dust, cotton-wool, PM10, PM2.5 etc.；Further include can be absorbed smell, removal air in part it is toxic
The active carbon net of gas such as formaldehyde；In order to pursue further air purification effect, the microorganism such as virus in air is killed
And bacterium, part of the manufacturer are additionally provided with negative ion generating device, usually by with photocatalysis effect photocatalyst and capable of emitting spy
The ultraviolet lamp composition of the long ultraviolet light of standing wave.Under the irradiation of ultraviolet lamp, photocatalyst can produce negative oxygen ion, the negative oxygen ion
The harmful microorganisms such as virus, the bacterium in air can be killed；Further include the blower for air-breathing, it is logical to generate enough wind-force
Cross filter net system and photocatalyst system.But filter screen has service life, the reason is that, the granular absorption in air
It can be accumulated on the net to thick effect and high efficiency filter, therefore adsorption effect can be reduced.Such as the efficient of 97% particle can be obstructed originally
Filter screen, after using the several months, obstructing capacity is reduced to 90%, and in seriously polluted environment, filter screen needs often cleaning
Or replacement, such as remove the dust being adsorbed on filter screen and particle using brush and be exposed to the sun in the sun, but this is relatively cumbersome.
Filter screen accounts for very big cost, if user is reluctant to replace, the long-term accumulated particles of filter screen and dust can become bacterium instead
Breeding ground, secondary pollution is caused, so that the effect of air purifier is had a greatly reduced quality.In addition, active carbon net also has the service life, activity
When charcoal adsorption moisture and remaining gas reach saturation, adsorption function is just lost, this is especially embodied under the wet weather in south
It obtains seriously.
Summary of the invention:
It is easily saturated for present air clarifier filter screen and active carbon net, loses and reduce detergent power, provide one
Kind has the photocatalysis air purifying device of self-purification capacity.
The technical solution is, the photocatalysis air purifying device with self-purification capacity, including, power supply, controller, shell,
Be fixed on the outer casing inner wall successively low efficient filter screen arranged in parallel, high efficiency particulate air, active carbon net, photocatalysis net, be located at
Ultraviolet lamp after the photocatalysis net, the first blower after the ultraviolet lamp；It further include filter screen disinfection and sterilization dress
It sets, is located in the shell, comprising: atomizing spray plate, water pipe, water tank, valve；The atomizing spray plate is located at the thick effect filtering
Net and the high efficiency particulate air side；Arrange that multiple atomizers, the atomizer pass through described on the atomizing spray plate
Water pipe is connected to the water tank, and the water tank is for containing thimerosal；The valve is set on the water pipe, and the valve is connected to institute
State controller；Active carbon drying device, comprising: heat-generating pipe, the second blower；The heat-generating pipe and the second blower are located at the activity
The side of charcoal net, the heat-generating pipe and second blower are connected to the controller.
Further, because increasing filter screen disinfecting device and active carbon drying device in filter screen and active carbon
The side of net can make part wind not to be cleaned so that having gap between filter screen, active carbon net and shell.In order to make
It obtains and is sealed between filter screen and shell, keep purifying rate, be also provided with mesospore, the shell is divided into the area Liang Ge by the mesospore
Domain, the low efficient filter screen, high efficiency particulate air, active carbon net, photocatalysis net, ultraviolet lamp, the first blower are located in one of area
Domain, the filter screen disinfector, the active carbon drying device are located at another region；
Further, the presence of mesospore has completely cut off filtration, purification system and self-purifying system, in order to enable the filter screen
The hot wind of disinfection atomized liquid and active carbon drying device can be transmitted to filter screen and active carbon net, and position is equipped on the mesospore
Opening in front of the shower plate, the active carbon drying device.
It further, further include electric push-and-pull closed plate, the electric push-and-pull closed plate is slidably connected on the mesospore
Close to the side of the filter screen sterilizing unit；The electric push-and-pull closed plate is connected to the controller, the electric push-and-pull
The opening can be closed under the control of the controller and be exposed to closed plate.
It further, further include ultraviolet light reflecting cover in order to enable light-catalysed utilization rate of ultraviolet light improves, it is described ultraviolet
Between the ultraviolet lamp and the blower, the ultraviolet light reflecting cover can be improved light reflecting cover with reflective portion ultraviolet light
The utilization rate of ultraviolet light.
Further, in order to adjust light-catalysed intensity, the ultraviolet lamp quantity be it is multiple, multiple ultraviolet lamps are connected to institute
Controller is stated, can control the quantity of ultraviolet lamp opening and closing by controller.
Its principle is, since filter screen, including low efficient filter screen and high efficiency particulate air are used for a long time, can all cause to filter
Net accumulates excessive dust, and filter screen is caused to block, and reduces the efficiency of filter screen, breeds bacterium, causes secondary pollution.This programme
Spray equipment is sterilized by the way that materialization is arranged in the side of filter screen, the thimerosal after atomization is sent to space locating for filter screen,
Effective killing effect is played for bacterium.Since active carbon uses under wet weather for a long time, active carbon absorbs moisture, non-
It often is easy to reach saturation, loses the effect of absorption.In order to make active carbon restore adsorptivity, by the way that active carbon drying device is arranged,
Using heat-generating pipe and blower, hot wind is blown to space locating for active carbon net, it is dry to facilitate active carbon.In order to enable filtering is net
Change system sealing, be also provided with mesospore, for completely cutting off filter screen and from disinfection and self-desiccation device, and passes through setting electric push-and-pull
Closed plate controls electric push-and-pull closed plate by controller, exposes the opening being located on mesospore when in use, so that atomization disappears
Venom and hot wind can be sent by opening to filter screen and active carbon net.In disinfection and after drying, controller pushes electronic
Closed plate closing opening is pushed and pulled, prevents wind from causing purifying rate to reduce by being open to leak out.
The advantageous effect of the invention is:
1, filter screen disinfecting device can effectively kill the bacterium that low efficient filter screen and high efficiency filter are bred on the net,
Secondary pollution is prevented, the number of manual cleaning filter screen is reduced.
2, the moisture adsorbed in active carbon can be effectively removed in active carbon drying device, so that active carbon recovered part is living
Property.
3, the utilization rate of ultraviolet light can be improved in ultraviolet light reflecting cover.
