Abstract

The utility model relates to an air purifying device, which is composed of a catalytic bed, a draught fan, an ultraviolet lamp, a power switch, an indicating lamp, a housing, an anion generator, a filter, a spice box, spices, an alarm device, and an automatic opening device. The catalytic bed is split into an internal portion and an external portion; the internal catalytic bed is spiral, and the external catalytic bed is in corrugation-shaped. The utility model has the advantages of large light irradiation area, small air resistance, lowered requirement to the power of the draught fan, and reduced noise. The air purifying device can provide strong assurances for the further improvement of the air quality of the space and the improvement of the reliability of the air purifying device.

Description

Light catalytic air purifying machine

The utility model relates to a kind of device that purifies air.

The device that existing employing photocatalysis principle purifies air, " air purifier " that be total to company with Japan three is example, is made of blower fan, catalytic bed, uviol lamp, power switch, indicator lamp, shell; Catalytic bed is divided into inside and outside two parts, interior catalytic bed is the shape of a saddle, outer catalytic bed is a tubular, connect with securing member between the inside and outside catalytic bed, all scribble the titanium dioxide semiconductor catalyst on the inside and outside catalytic bed, blower fan is loaded in the shell, and links to each other with outer catalytic bed, uviol lamp is loaded in the catalytic bed, and links to each other with interior catalytic bed; Catalytic bed is loaded on the center of shell, and power switch, indicator lamp all are loaded on the lower right of shell, has air outlet and air inlet on the shell.Though this air purifier can reach the purpose that purifies air, because catalytic bed adopts the shape of a saddle in it, illuminating area is little, and air drag is big, installs also inconvenient.

The purpose of this utility model is to make a kind of illuminating area that can increase catalytic bed, reduce air drag, raise the efficiency, reduce the new air cleaning unit of noise.This device is of value in improving air cleanliness and dependability, increase air and also can contributes aspect the composition of human body.

The purpose of this utility model is achieved in that and changes interior catalytic bed 4 into spirality by the shape of a saddle, change outer catalytic bed 5 into corrugation shape by tubular, and in the utility model, increased spice box and anion generator 1, filter 13, carbon monoxide and flammable explosive gas exceed standard warning device 8, auto power on device 9.Spice box and anion generator 1, filter 13 are loaded on air outlet 11 places of shell, and exceed standard warning device 8 and auto power on device 9 of carbon monoxide and flammable explosive gas all is loaded on air inlet 10 places of shell.An exceed standard termination power of warning device 8 and auto power on device 9 of carbon monoxide and flammable explosive gas, the other end give a dinner for a visitor from afar machine 3 and uviol lamp 6, spices places spice box.

Further improvement of the utility model be its employed spices with santal, cloves, three how, essence makes.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model mesa structure schematic diagram;

Fig. 2 is the utility model console mode structural representation;

Fig. 3 is the wall-hanging structural representation of the utility model;

Fig. 4 is the utility model electronic circuit schematic diagram.

Wherein:

1--spice box and anion generator 2--micro machine

Catalytic bed in the 3--wind wheel 4--

The outer catalytic bed 6--uviol lamp of 5--

7--shell 8--warning device

9--auto power on device 10--air inlet

11--air outlet 12--switch and indicator lamp

The 13--filter

Accompanying drawing 1 and 4,2 and 4,3 and 4 constitutes the embodiment of three different profiles of the present utility model respectively, promptly keeping under the constant situation of the utility model internal structure, it can be designed to the different patterns of console mode (as Fig. 2), desk-top (as Fig. 1), wall-hanging (as Fig. 3), with the instructions for use of convenient different occasions.The utility model is work like this: power-on, and the indication lamp housing, uviol lamp is lighted thereupon, sends the ultraviolet ray irradiation catalytic bed of wavelength 25 μ m, and the titanium dioxide semiconductor catalyst that is coated on the catalytic bed is subjected to optical excitation to produce hole and electronics.Meanwhile, blower fan attracts air by catalytic bed from air inlet in rotation, is subjected to the light induced electron effect, and airborne pernicious gas molecule is broken down into the innocuous gas molecule.The air that purifies through above-mentioned way flows through filter and spice box at air outlet, and the dust that particle in the air is bigger filters away, brings nontoxic aroma gases into space.

If in power-on, open anion generator, also can in the air of inflow space, increase negative oxygen ion, thereby further improve the quality of the air of inflow space the human body beneficial.

If in the bedroom the utility model is installed, can before sleeping, be opened carbon monoxide and flammable explosive gas alarm.When indoor carbon monoxide and flammable explosive gas concentration surpass state-set standard, by the gas sensor perception that is contained in the air inlet place and produce voltage, control the utility model is opened automatically after alarm amplifies, meanwhile, buzzer sends alarm signal, thereby reliability of the present utility model is further improved.

Because the utility model catalytic bed architecture advances, thereby increased the illuminating area of catalytic bed, reduced air drag, reduced requirement, noise is reduced thereupon power of fan.Anion generator in the utility model, filter, spice box, spices, carbon monoxide and the flammable explosive gas warning device that exceeds standard, the increase of auto power on device, the utility model is not only had the ability when the photoactivation principle purifies air, contain the anion that is of value to human body and can refresh oneself and more high-quality air that nontoxic aromatic odor and the dust that particle is bigger filter away for the space provides, and under off-mode, when carbon monoxide in the space and flammable explosive gas surpass state specified standards, when can also send alarm signal, automatically open air cleaning unit, this has just further improved practicality of the present utility model and reliability.
