With above technical scheme, following beneficial effect can be reached：
1, the present invention can be avoided the inaccurate type of the complicated and existing measurement means of the means of existing measurement, and energy
It is enough that underproof strainer is only measured by air velocity transducer.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the air purifier of strainer life testing method of the invention；
Fig. 2 is the uniformly distributed schematic diagram of the air quantity near a kind of ventilation shaft of strainer life testing method of the invention.
In attached drawing：1, air purifier；12, air inlet；13, air outlet；21, middle effect strainer；3, ventilation shaft；
A, five different locations of b, c, d and e, air outlet；
A, five different locations of B, C, D and E, air inlet.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Strainer is for imitating strainer 21 in being only arranged in Fig. 1 and Fig. 2.Fig. 1 is a kind of strainer life test of the invention
The schematic diagram of the air purifier of method；Fig. 2 is the wind near a kind of ventilation shaft of strainer life testing method of the invention
Measure uniformly distributed schematic diagram.
It is shown in Figure 1, in a kind of preferred embodiment, a kind of strainer life testing method, which is characterized in that packet
It includes：
Step 1: placing an air velocity transducer at the air inlet 12 of air purifier 1.
Step 2: imitating strainer 21 in test, middle effect strainer 21 is only set in air purifier 1, tester selects service life inspection
Survey mode reads air quantity data by air velocity transducer；If air quantity data are less than the specified minimum air quantity of middle effect strainer 21, replace
Middle effect strainer 21, conversely, then continuing to use middle effect strainer 21.
Step 3: testing efficient filter, efficient filter is set in air purifier 1, tester selects life tests mode,
Air quantity data are read by air velocity transducer；If air quantity data are less than the specified minimum air quantity of efficient filter, efficient filter is replaced,
Conversely, then continuing to use efficient filter.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention.
Further, in a kind of preferred embodiment, it is provided with adding thermal resistance in air velocity transducer, air velocity transducer is via adding
The heat losses of thermal resistance measure wind speed.Specifically, the flow of adding thermal resistance is lost, there are corresponding relationship, heats with wind speed size
Loss will lead to resistance variations, to change size of current.I.e. according to the change of electric current it can be concluded that wind speed.
Further, in a kind of preferred embodiment, air quantity data are equal to the product of wind speed and pipeline open area；Such as wind speed passes
Sensor is set to air inlet 12, then the air quantity data of air inlet 12 are equal to the product of the pipeline open area of wind speed and air inlet 12；Example
If air velocity transducer is set to air outlet 13, then the air quantity data of air outlet 13 are equal to the pipeline open area of wind speed and air outlet 13
Between.
Further, in a kind of preferred embodiment, air quantity can be adjusted to maximum gear automatically by life tests mode.
Further, in a kind of preferred embodiment, the principle of the invention lies in middle effect strainers 21 and efficient filter to use
Particulate pollutant can be all accumulated, in the process so as to cause resistance rising, air quantity decline.Therefore, it can use air volume to sentence
Whether the disconnected service life expires.
Further, in a kind of preferred embodiment, specified minimum air quantity, that is, air purifier of middle effect strainer 21 is only installed
Minimum air quantity when middle effect strainer 21 is without efficient filter；The measuring principle of minimum air quantity is as follows：Air purifier is only installed
In the case where middle effect strainer 21, when testing the CADR obtained and being reduced to the 50% of initial CADR, air quantity at this time be in effect filter
The specified minimum air quantity of net 21；The principle of the setting of the specified minimum air quantity of efficient filter is same as above, and details are not described herein.
Further, shown in Figure 2 in a kind of preferred embodiment；As can be seen that wind is passed through from ventilation shaft 3 in figure
Effect strainer 21 (Fig. 2 is by taking middle effect strainer 21 as an example) is crossed, wind concentrates on the middle and upper part point of middle effect strainer 21, wind is caused to be unevenly distributed
It is even, therefore measurement is to cause air measuring inaccurate, so that the reliability of strainer life testing method of the invention reduces.
For the case where avoiding the reliability of strainer life testing method described in a upper embodiment from reducing, the present invention couple
Being set to air inlet or air outlet also in air velocity transducer has following judgment method：
Step 1: air velocity transducer to be set to five different locations (A, B, C, D and E) of air inlet 12, five are measured
Different air inlet airflow values；Air velocity transducer is set to five different locations (a, b, c, d and e) of air outlet 13, measures five
A difference air outlet airflow value.
Step 2: first party difference is obtained via five different air inlet airflow values, via five different air outlet air quantity
It is worth second party difference.
Step 3: air velocity transducer is installed on air outlet 13 when first party difference is greater than second party difference；Work as first party
Difference is less than second party difference, and air velocity transducer is installed on air inlet 12.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention, right
For those skilled in the art, it should can appreciate that and all replace with being equal made by description of the invention and diagramatic content
It changes and obviously changes obtained scheme, should all be included within the scope of the present invention.
