Description

A kind of intelligent air freshener

Technical field

The present invention relates to the electric equipment of field of Environment Protection, be specifically related to a kind of intelligent air freshener.

Background technology

Along with industry and social development, the continuous increase of population, global air pollution is day by day serious, and human health is being faced with the threat of " room air pollution ".Present people's live and work is all mainly indoor, and our IAQ worse and worse.Research shows in room air, there is a large amount of pollutants.In our daily indoor life, also can produce a large amount of pollutants, such as result of combustion of tobacco, various solvent, paint, computer and printer, wallpaper, carpet etc. all can produce pollutant.Some places are coal combustion, can produce the pollutants such as sulfur dioxide.In room air, also have a lot as pellets such as dust, smog, bacterium, scurf, hairs etc.Meanwhile, the use due to increasing household appliances, makes airborne negative ion concentration more and more lower.These pollutants in Interior Space have very large harm to our health, various suspended particulate substances also can spread disease, and the favourable anion concentration of our human body is become still less.

Although many countries have tentatively set up air quality standard, examination criteria and analytical standard, on market, Development and Production goes out various Detection of Air Quality, collection, analysis and air cleaning unit, it is too complicated that but the air purifier on market has plenty of operation now, a large amount of mechanical operation; Have plenty of can not be real the effect that realizes air cleaning, or can not automatically detect air quality and operate accordingly.

Summary of the invention

Goal of the invention: in order to solve the deficiencies in the prior art, actuating air freshener is to intelligent, scientific future development, of the present inventionly provides a kind of intelligent air freshener.

Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is:

A freshener, the sensor group that comprises controller and be connected with controller respectively, anion generator, air circulation purifier, motor drive module and man-machine interface.

Described controller is the minimum system that ATmega8 forms, ATmega8 adopts 8 single-chip microcomputers based on AVR risc architecture of Low-Power CMOS explained hereafter, core is that 32 work registers and abundant instruction set are bound up, all work registers all with ALU(ALU) be directly connected, realized the operation that two independent register are accessed in an instruction of carrying out simultaneously within a clock cycle.This structure has improved code efficiency, and the time of implementation that makes most of instruction is only a clock cycle.Therefore ATmega8 can reach the performance that approaches 1MIPS/MHz, and the speed of service exceeds 10 times than common CISC single-chip microcomputer.

Described sensor group comprises peculiar smell sensor and sensor of dust concentration.Peculiar smell sensor is TGS2600, the smog of cigarette or cooking stink are had to very high sensitivity, this sensor is to utilize relative value to detect to realize more to approach the control that the mankind feel, when take air cleaner, be benchmark, by sensor electrical resistance, changed the pollution level that how much detects air during than air cleaner.Heater current is very little, only has 42mA, uses the fixed voltage of DC5V, very easy to use.

Described air circulation purifier comprises successively connected silver ion screen pack, filter cotton, activated charcoal strainer and ultraviolet-sterilization layer.Silver ion screen pack adopts melt spinning to improve technology, at net material, adds strong, the most most widely used metal antibacterial agent silver ion of performance, can effectively suppress all kinds of germs, mainly filters hair, fiber, pollutant that insect corpse equal-volume is larger; Filter cotton is to be interwoven mutually by polyster fibre, be network structure, can stop airborne bulky grain dust or foreign matter, mainly for suspension particulate more than 5um and settleability particulate more than 10um and various bulky grain foreign matter, prevent in its access arrangement, reach protection equipment, the object increasing the service life; It is raw material that activated charcoal strainer adopts charcoal, bamboo charcoal, various shell and fat coal etc., through fragmentation sieve, catalyst activation, rinsing, oven dry and screening process, there is efficient absorption property, the pernicious gases such as absorbing formaldehyde, benzene homologues, ammonia, TVOC, can effectively remove pernicious gas and the peculiar smell such as Ammonia in Air gas, acetic acid.

Anion generator output DC high voltage, ionized air produces high-concentration anion, can reach smoke elimination, dedusting, elimination peculiar smell, improve air quality, the effect promoting health.

Also comprise alarm module, when the indices in environment surpasses warning value, controller drives alarm module to report to the police.

Described motor drive module comprises single-phase asynchronous alternating current generator and fan.

The course of work of intelligent air freshener is as follows: the work of controller starter motor driver module, fan drives air circulation, by peculiar smell sensor and sensor of dust concentration, the air information collecting is uploaded to controller, information after collection drives air cleaning EGR and anion generator work after treatment, man-machine interface is for query-related information and input air quality warning value, when air quality surpasses warning value, controller drives alarm module to send alarm sound, and shows current information in man-machine interface.

Beneficial effect: the intelligent air freshener providing of the present invention, integrate single-chip microcomputer control technology, lcd technology, automatic data collection technology, sensor technology, electric machines control technology and sterilization technology, can realize indoor air purification, solved the series of problems of the aspects such as safety, environmental protection and effect, aim at home and use and make to measure, meet family disinfection standard, the advantage such as advanced, easy to operate, economical and effective of possessing skills, can wide popularization and application.
