Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

When using this device for air purification, the air to be purified is introduced into the purifier through the air inlet, and its power comes from the exhaust fan 16 in the air outlet 15; the air entering the interior of the purifier is first filtered by replaceable activated carbon air. Net 11 utilizes the double adsorption of the hole surface of activated carbon air filter screen 11, the characteristics of large material adsorption capacity, to filter harmful particles such as dust, smog, stink, peculiar smell, toluene, methyl alcohol, bacteria in the air. The activated carbon air filter screen 11 can be replaced at any time by the activated carbon filter screen replacement port 10.

The air through the active carbon air filter 11 reaches the irradiated area of the far ultraviolet lamp 19. The far ultraviolet lamp 19 uses the far ultraviolet wave band with strong bactericidal ability to irradiate microorganisms with ultraviolet rays to change and destroy the organizational structure (DNA-nucleic acid) of microorganisms. , leading to nucleic acid structure mutations, organisms lose their ability to replicate and reproduce, and their functions are destroyed, so as to achieve the purpose of disinfection and sterilization.

The air after the far-ultraviolet lamp 19 irradiation area reaches the photocatalyst air purification net 18, filters the air again, and directly oxidizes the organic pollutants in the air into non-toxic and harmless substances. Carbon tetrachloride and hexachlorobenzene can be effectively decomposed. Photocatalysts are effective for many types of organic substances from hydrocarbons to carboxylic acids, even for atomic organic substances such as halogenated hydrocarbons, dyes, nitrogen-containing organic substances, and organophosphorus pesticides. It also has a good removal effect. Generally, the effect of complete purification can be achieved after continuous reaction.

In order to make the output air fresh, a negative ion generator 17 is added in the device. The negative ion generator 17 produces high pressure to ionize the air and generate negative ions, which are used to absorb dust and kill bacteria.

In order to achieve the reasonable combination of the work of various air purification methods such as active carbon air filter screen 11, far ultraviolet lamp 19, photocatalyst air purification screen 18, negative ion generator 17, wind speed sensor 12, humidity sensor 13, detection control circuit 14.

The detection control circuit completes wind speed detection, ambient humidity detection and air purification time, ambient humidity, air volume cycle display, and internal control of the ultraviolet lamp, negative ion generator 17 and peripheral humidifier connected to the device in the device.

On the surface of the shell 1, there are far-ultraviolet working indicator lights 2, an activated carbon filter replacement port 10, a keyboard 5 on the front, a wind speed adjustment knob 6, an air inlet 7, a status display indicator 8, a display 9, and an external connection on the side. Humidifier control interface 4 and power cord 3, inside the housing 1, there is a wind speed sensor 12 and a humidity sensor 13 arranged side by side between the air inlet 7 and the activated carbon filter 11, and the activated carbon filter 11 is installed sequentially inward from the air inlet 7 , far ultraviolet lamp 19, photocatalyst air purification net 18, negative ion generator 17, exhaust fan 16, they are all independent components, are fixed on the inner bottom surface of housing 1 by screws, exhaust fan 16 is a cylindrical axial flow fan, tight Close to the air outlet 15 on the back side of the housing 1, the left end in the housing 1 is equipped with a detection control circuit (14), and the inner top surface of the housing 1 and the bottom of the far ultraviolet lamp 19 are pasted with tinfoil for reflection.

The single-chip microcomputer is the core of the detection control circuit part. The single-chip microcomputer receives the pulse signal of the wind speed sensor 12 through the comparator circuit, calculates the air volume, and sends it to the display 9 for display, so as to determine the required purification time according to the size of the room volume; (Voltage Controlled Oscillator) and the amplifier receive the signal of the humidity sensor 13 to obtain the humidity value of the indoor air, send it to the display 9 for display, and control the power supply of the humidifier through the triode T2 and the relay J2 according to the set value, so that according to the setting The external air humidifier is opened and closed by value; the internal program control of the single-chip microcomputer receives the input of the keyboard 5, and its input data is purification time and humidity setting value; the internal program of the single-chip microcomputer also controls the work of the far ultraviolet lamp 19 and the exhaust fan 16 motor.
