Fig. 2 show the structure diagram of filter screen life estimate device disclosed according to the present invention.
Specific embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and attached drawing clear
Chu, complete description, to be completely understood by the purpose of the present invention, scheme and effect.It should be noted that in situation about not conflicting
Under, the feature in embodiment and embodiment in the application can be mutually combined.The identical attached drawing mark used everywhere in attached drawing
Note indicates the same or similar part.
With reference to the flow chart of disclosed filter screen life estimation method according to the present invention shown in FIG. 1, the present invention's
In one embodiment, for the filter screen life estimation method of air purifier, comprise the following steps：Pass through sensor group convection current
Air through air intake vent and air outlet is sampled, and the sensor group is configured as calculating air quality ginseng according to sampled result
Number X；The air quality parameters X is responded, processor calculates the life factor K of filter screen and the working speed F of motor；Based on electricity
The working speed F of machine and the device parameter of air purifier, processor calculate the unit interval purge amount of air purifier；
And the life factor K based on filter screen, processor calculate the single use service life L of air purifier.
Wherein, air quality parameters X is under current environment, and filtered air pollutant weight is needed in unit volume.It crosses
The life factor K of strainer be with the relevant coefficient of filter screen depletion rate, be filter out that Unit Weight pollutant consumed when
Between.The pollutant being accumulated in since air quality is poorer, in the unit interval on filter screen is more；Therefore, in its external condition phase
With in the case of, life factor K and air quality parameters X is negatively correlated.Specifically, when air quality is poorer, (i.e. air quality is joined
Number X it is higher), and air flow speed it is constant in the case of, unit interval filtering net depletion rate is faster, the longevity of filter screen
It is smaller to order COEFFICIENT K.When filter screen works under best air quality, life factor K is 1；As air quality declines, the longevity
Life COEFFICIENT K reduces and is remained above 0.Usually, life factor K can be measured by the product to concrete model by experiment
It arrives.In one embodiment, when air quality is poorer, i.e., sensor group sample and calculate gained air quality parameters X it is higher when,
Air purifier just needs to be arranged on the working speed of motor in air purifier by improving, accelerate air from air intake vent to
The flowing velocity of air outlet so that more air streams pass through strainer in the unit interval.
The present invention the above method in, the air quality parameters X be based on acquired in sensor group include still
It is not limited to temperature, humidity, PM2.5, carbon dioxide, total volatile organic compounds (TVOC, Total Volatile Organic
Compound) data or its any combination.Specifically, due to the The concrete specification of filter screen and the difference of type, so filter screen
It is also different to the processing capacity of various pollutants.Therefore, the data for each pollutant that sensor group is obtained, will be according to specific
Air purifier model institute predetermined manner, calculate current air quality parameters X, i.e. unit volume filtering net needs to filter
Air pollutants weight.
In the above method of the present invention, the life factor K is at least divided into three according to the air quality parameters X
A grade.Further, the working speed F is at least divided into three grades according to the air quality parameters X.Although the longevity
The grade quantity for ordering COEFFICIENT K is not necessarily identical with the grade quantity of working speed F；But it is faster to represent filter screen depletion rate
Life factor K grade (i.e. air quality is poorer), the grade of corresponding working speed F represents the working speed F of motor
It is faster.In other words, when air quality poorer (i.e. air quality parameters X is bigger), the corresponding filter screen depletion rate faster longevity
The grade of the grade for ordering COEFFICIENT K and the faster working speed F of working speed F for representing motor.
In one embodiment, life factor is arranged to K1、K2And K3Totally 3 grades and for 1=K1>K2>K3>0.Work as sky
When gas mass parameter X is bigger, corresponding life factor is smaller.In the above-described embodiments, working speed is arranged to F1、F2And F3
Totally 3 grades and for 0<F1<F2<F3.When air quality parameters X is bigger, corresponding working speed is bigger.Air purifier can
With the actual air mass situation according to present vicinity region, the working speed of adjust automatically motor so that air can be with appropriate
Speed flow through filter screen, so as to filter screen can it is abundant cross air filtering in pollutant.Meanwhile the actual sky in present vicinity region
The lasting slight change of gas quality condition, will not cause the working speed of motor frequently to adjust so that air purifier is opposite
It works in the state of steady.
In the above method of the present invention, the device parameter includes at least outlet air open area S and wind speed coefficient N.Wherein,
Wind speed coefficient N is the speed for the air for flowing through filter screen and the ratio of the working speed F of motor at this time, so as to according to wind speed coefficient
The working speed F of N and current motor can calculate the speed of the current air for flowing through filter.Wind speed coefficient N can be by tool
The product experiment measurement of build number obtains.
Further, in the above method of the present invention, processor utilizes formulaSky is calculated
The single use service life L of gas purifier.It is consistent with above that each in above-mentioned formula meets representative meaning, that is, passes through calculating
The air quantity of filter screen is flowed through within the unit interval, and according to current air mass parameter X, calculates the single use of air purifier
Service life L.
In the above method of the present invention, processor according to filter screen it is current purify value WoldWith air purifier
Service life L is intended for single use, update filter screen purifies value Wnew=Wold-L.Wherein, it is that filter screen can filter out pollution that can purify value
The total weight of object.Specifically, before product export, manufacturer can be according to specific air purifier product type and filter screen
Type, set above equipment parameter and initialization can purify value Wold.User in use, WoldIt will be according to above-mentioned side
Formula is constantly updated.After replacing same type filter screen or cleaning up filter screen, value W can be purifiedoldIt will revert to original
Initial value, so as to carry out the filter screen life estimate of a new round.
In the above method of the present invention, sensor group is at least frequency once per minute to flowing through air intake vent and outlet air
The air of mouth is sampled, and with the actual air mass situation in the present vicinity region that upgrades in time, and is adjusted according to actual needs
The working speed of motor.
Further, in the above method of the present invention, processor is empty to be not less than the update of the frequency of the sampling of sensor
The unit interval purge amount of gas purifier and the single use service life L of air purifier.
Further, when purifying value less than default threshold value of filter screen after update, air purifier will pass through
The suggestion device being arranged on air purifier issues the user with prompting.Wherein, suggestion device may include but be not limited to buzzing
Device, emergency warning lamp, LED display or their any combination.
