Description
Technical field
The present invention relates to air purifier technical field, particularly a kind of air purifier based on signal conditioning circuit
Automatic cleaning system.
Background technology
With being continually changing for global climate and frequently occurring for various extreme climates, air purifier has become people
Requisite household electrical appliance in daily life.But can assemble on the drainage screen inside commonly used air purifier
Substantial amounts of dust, antibacterial and mycete, are both unfavorable for divulging information and affecting to heat or refrigeration, are less useful for the health of human body.In
Center for Disease Control (CDC) of state data shows, if air purifier is seriously polluted to cause sub-health state and various diseases.But this
One problem does not cause the enough attention of people, many people that the custom of drainage screen is often cleaned without Jing.
With the improvement of people's living standards, people pay attention to all the more health.Air pollution at present is serious, IAQ (indoor air quality)
Increasingly it is subject to people's attention.What is played a major role in air purifier is drainage screen, and drainage screen has certain use longevity
Life.Drainage screen not only can collect dirt dust, as temperature, humidity are suitable, drainage screen can also grow big under condensed water effect
Amount antibacterial, mycete, acarid etc..When drainage screen is opened, these dusts and pathogenic bacteria are just produced by boasting by drainage screen, enter with respiratory tract
Human body, causes human body to occur dizzy weak, catches cold, allergic rhinitises, or even induction asthma.Environmental science association of state is indoor
Environment combines Shanghai man of man peace with healthy branch carries out tune of registering one's residence to the Household Air Purifier on the ground such as Shanghai, Beijing, Shenzhen
Research and development are existing, and 88% drainage screen total number of bacteria is exceeded, and 84% drainage screen total number of molds is exceeded, and antibacterial highest is detected on drainage screen
Up to 91259/cm2.In order to avoid drainage screen is excessively used, common way is the use time for counting drainage screen, once
Use time service life more than expected, will be prompted to user and is changed.This method is realized simply, while there is also substantially
Deficiency；Air quality due to have ignored use environment, in the preferable environment of air quality, possible use time reaches pre-
If value when, drainage screen can also continue to use, now change can cause waste；But in the poor environment of air quality,
Then occur that drainage screen has reached operating limit, but air purifier still will not be reminded, this will endanger the strong of people
Health.
Therefore, filtering network pollution becomes one of principal element of harm family health care.But at present, this problem is not
There is the enough attention for causing people.After long-term use, the airstrainer installed in air inlet position can glue air purifier
Upper many dusts, cause drainage screen air bound or obstructed, affect the working effect of air purifier.At present, it is most of empty
Gas purifier is required in use for some time removing drainage screen and carries out Manual-cleaning.For being unfamiliar with air purifier structure
User and for can not skillfully completing the user of Manual-cleaning air purifier, the affairs are into using air purifier
When a burden, or the personage of specialty can only be entrusted to assist operation, or simply ignore the drainage screen after life-time service
The problem of meeting secondary pollution air ambient is possible to, air purifier is continuing with and is not cleaned.It is total well known, if air is net
Change device to use daily and if irregularly cleaning, still have many antibacterials and micronic dust can be rested on drainage screen, make human body
Into very big injury, service life of a machine can be also shortened.
