Line connection, or be wirelessly connected (such as bluetooth, wifi etc.), etc..
On the other hand, the present invention also provides a kind of control methods for air filter, with air above-mentioned
For filter device, as shown in figure 4, control method of the invention includes: to obtain the particle size of exceeded pollutant in air；Root
The distance between more vertical silk threads 22 of the distance between more lateral silk threads 21 are adjusted according to the particle size of exceeded pollutant.
The time of filtration of strainer 2 is adjusted according to the particle size of exceeded pollutant.Wherein, pollutant is provided on air filter
Detector obtains the particle size of exceeded pollutant in air by contaminant detector, then according to of exceeded pollutant
Particle size adjusts the time of filtration of strainer 2, for example, if the exceeded pollutant in air is PM2.5, by the filtering of strainer 2
Gap adjustment is to meet the size of filtering PM2.5, not only can guarantee effective filtering to PM2.5, but also can be improved the mistake to PM2.5
Filtering velocity rate；If exceeded pollutant is PM0.3 in air, the time of filtration of strainer 2 is adjusted to meet the ruler of filtering PM0.3
It is very little, it not only can guarantee effective filtering to PM0.3, but also can be improved the filtering rate, etc. to PM0.3.It is of course also possible to by empty
Gas filter device is connect with cloud server, and the particle size, etc. of exceeded pollutant in air is obtained by cloud server,
This adjustment and change to the concrete mode of the particle size of exceeded pollutant in acquisition air is without departing from original of the invention
Reason and range, should all limit within protection scope of the present invention.
On the other hand, the present invention also provides the control methods that another is used for air filter, with above-mentioned
For air filter, as shown in figure 5, control method of the invention includes: the concentration value for obtaining dust in air；According to powder
The concentration value of dirt adjusts the distance between more vertical silk threads 22 of the distance between more lateral silk threads 21.I.e. according to dust
The time of filtration of concentration value adjusting strainer 2.In a kind of possible situation, air filter above-mentioned is applied to smart window
On, under normal conditions, the pollutant in outdoor air enters interior in order to prevent, and the time of filtration of strainer 2 is typically small, and
When interior is fitted up or carries out general cleaning, a large amount of dust can be generated, so that the concentration value of house dust is caused to increase,
In order to avoid influencing the health of user, fast dust-removing is needed, at this time, it may be necessary to which the time of filtration of strainer 2 is tuned up, then is cooperated
The equipment such as blower or fan rapidly remove the dust in room air；Wherein it is possible to which setting dust concentration detects indoors
Device, and communicate dust concentration detector with the control system of smart window (communication mode uses wired connection, or such as
The wireless connection of bluetooth, wifi etc.), so as to the dust concentration into the control system of smart window feedback room air in time
Value.
Preferably, as shown in figure 5, " adjusting the distance between more lateral silk threads 21 according to dust concentration value among the above
The step of the distance between more vertical silk threads 22 ", specifically includes: dust concentration value is compared with preset value；If
Dust concentration value reaches preset value, then adjusts the distance between more lateral silk threads 21 to the first maximum distance and will be more
The distance between vertical silk thread 22 of root is adjusted to the second maximum distance.I.e. when dust concentration value reaches preset value, by strainer 2
Time of filtration adjust to maximum filtering gap, in this case, illustrate that dust concentration value has severely exceeded, for reality
Existing fast dust-removing, it should adjust the time of filtration of strainer 2 to maximum value.It should be noted that those skilled in the art can be with
The specific value of preset value is flexibly set in practical applications, as long as can by the dust concentration cut off value that preset value determines
Judge whether the dust concentration in air severely exceeds.
Preferably, as shown in figure 5, " the distance between more lateral silk threads 21 are adjusted to the first maximum distance and
The distance between more vertical silk threads 22 are adjusted to the second maximum distance " the step of after, control method of the invention is also wrapped
It includes: obtaining dedusting time；If dedusting time reaches preset time, the distance between more lateral silk threads 21 are adjusted to the
One pre-determined distance and the distance between more vertical silk threads 22 are adjusted to the second pre-determined distance；Wherein, the first pre-determined distance
Less than the first maximum distance, the second pre-determined distance is less than the second maximum distance.After dedusting time reaches preset time, illustrate air
Middle dust concentration value is normal, no longer needs to be dusted, and at this time adjusts the distance between more lateral silk threads 21 to the
One pre-determined distance and the distance between more vertical silk threads 22 are adjusted to the second pre-determined distance, with prevent outdoor pollutant into
Enter interior.It should be noted that those skilled in the art can flexibly set the specific number of preset time in practical applications
Value, as long as can judge whether the concentration value of dust in air returns normal value by the time separation that preset time determines
?.
On the other hand, the present invention also provides the control methods that another is used for air filter, with sky above-mentioned
For gas filter device, as shown in fig. 6, control method of the invention includes: to judge whether strainer 2 needs to be cleaned；If filter
The needs of net 2 are cleaned, then will the adjusting of the distance between more lateral silk threads 21 to the first maximum distance and by more vertical silks
The distance between line 22 is adjusted to the second maximum distance.I.e. when the needs of strainer 2 are cleaned, the time of filtration of strainer 2 is adjusted
Be conducive to maximum filtering gap by adjusting the time of filtration of strainer 2 to maximum filtering gap by the impurity on strainer 2
Quickly remove.Wherein it is possible to the time is used by acquisition air filter, if reaching preset time using the time,
Illustrate that the needs of strainer 2 are cleaned, it is of course also possible to whether judge strainer 2 by other modes such as the pressure differences of 2 two sides of strainer
Need to be cleaned, it is this to judge strainer 2 whether need by the adjustment of clean concrete mode and change without departing from the present invention
Principle and range, should all limit within protection scope of the present invention.It should be noted that can be on air filter
Automated cleaning component is set to clean to strainer 2, for example, dust catcher can be arranged on air filter, when strainer 2
When needing to be cleaned, it can star dust catcher and strainer 2 cleaned；Electric cleaning can also be set on air filter
Brush can star electric cleaning brush and clean to strainer 2, etc. when the needs of strainer 2 are cleaned；Alternatively, can be in air
Prompting device is set on filter device, when the needs of strainer 2 are cleaned, reminds user to carry out strainer 2 by prompting device artificial clear
Clean, etc., the adjustment and change of this specific cleaning mode to strainer 2, should all without departing from the principle and scope of the present invention
It limits within protection scope of the present invention.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
