Embodiment

Fig. 1, Fig. 2 are referred to, those shown is the first embodiment of filter structure provided by the utility model, and it mainly includes There is a filter screen body 1, the filter screen body 1 has a filter layer 11, and the wherein filter layer 11 can be made by adhesive-bonded fabric material.Should Filter layer 11 is wavy through being continuously bent to form, and thereby increases the filter screen body 1 in unit length and can be used to air filtering Area, increase filter effect.

Hold, on the surface of the filter layer 11 can visual position be covered with a judging part 21, the judging part 21 covers If area is less than the entire area of the filter layer 11, and can visually distinguish the judging part 21 and the filter layer 11, pass through dust The degree of the judging part 21 is covered using as judging the dirty foundation of the filter layer 11, and can be used to decide whether more for user Change the filter screen body.In this first embodiment, the judging part 21 is on the surface of the filter layer 11 by screen painting mode One is formed to be formed in strip and the printing layer that can substantially distinguish with the filter layer 11；Further, in order to for user The obvious interpretation filter layer 11 of energy and the judging part 21, more the judging part 21 that be made up of printing layer can be made and the filter layer 11 With different colors or the different depths, and can naked eyes fast resolution go out the filter layer 11 and the judging part, and judge it Degree of fouling.

The utility model formed with above-mentioned component and configuration mode can be used for air conditioner 3 as shown in Figure 3, such as Fig. 4 institutes The air cleaner 4 or air filter for vehicle 5 as shown in Figure 5 shown.And the filter screen body 1 is during use, by this The dust 9 that filter screen body 1 filters out can be accumulated in the filter layer 11, thus forms dust 9 as shown in Figure 6 and gradually cover the judging part 21 phenomenon；When using a period of time after, the dust 9 of accumulation gradually increases, thus the judging part 21 it is shielded degree it is gradual Increase, the degree that user can be shielded according to the judging part 21, to decide whether to change new product.For example, work as the judging part 21 is completely obscured by dust 9, and when causing to go beyond the visibility of the judging part 21, that is, represents the dust 9 of accumulation too much, enough To influence filter effect, then user can judge that the filter screen body 11 must be changed at once rapidly, in order to avoid influence body Health.Accordingly, the utility model by the judging part 21 by degree that dust 9 covers as judging whether dirty to need to change Standard, and good balance can be obtained between filtering efficiency and replacement cost.
