Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail specific embodiment of the utility model below in conjunction with accompanying drawing.
See Fig. 3, the utility model embodiment provides a kind of air conditioner filter 100, comprises Wrinkled filter core 110 and bundle limit 120, and filter core 110 is along fold direction X fold and form multiple interconnective continuous ruffle, filter 100 and the contact area of air can be strengthened like this, improve filter effect.
In Wrinkled filter core, multiple continuous ruffle forms multiple v-shaped structure by fold, in the present embodiment, the half of each v-shaped structure is defined as a ruffle.
Ruffle comprises multiple middle pleat 111 and two last pleats 112.Wherein, being positioned at filter core 110 along two ruffles of two ends of fold direction X is last pleat 112, and all the other are middle pleat 111, have connecting portion between last pleat 112 and middle pleat 111.That is, in all ruffles, the ruffle between last pleat 112 is all called middle pleat 111 (only having marked pleat in the middle of part in Fig. 3).
Bundle limit 120 is positioned at the both sides of filter core 110 along ruffle length direction Y, and is tightly connected with all middle pleat 111 in ruffle.The effect of fixing middle pleat 111, for being linked together by all middle pleats 111, is played in bundle limit 120, and the middle pleat 111 of restriction is along the movement of fold direction X, thus defines the bulk of described filter core 110.Can not be changed by the angle between the ruffle that bundle limit 120 is fixing, and ruffle can be prevented so loose and cause the distortion of filter.
Shown in Fig. 3 composition graphs 4, in the present embodiment, whole last pleat 112 is not connected with bundle limit 120, and, the connecting portion of two last pleats 112 and adjacent middle pleat 111 is positioned at the same surface (or filtering surface) of filter core 110, and namely two last pleats 112 are identical with the opening direction of angle between adjacent middle pleat 111.That is, in ruffle, only, pleat 111 is connected with bundle limit 120, and two last pleats 112 are free end, and this free end can move relative to middle pleat 111.Wherein, all middle pleats 111 are bonded together by viscose glue with bundle limit 120.
With reference to shown in Fig. 5, there is in air conditioning for automobiles the housing 200 for mounting filter 100, there is in housing 200 the track (not shown) for sliding for filter 100, filter 100 adopts the mounting means of drawer type to be installed in housing 200: filter 100 has the outlet air surface b of air intake surface a towards air intake direction and described air intake surface a dorsad, during installation, filter 100, towards air inlet, loads in housing 200 along track along the direction (direction as perpendicular to paper in Fig. 5) parallel with air intake surface a by air intake surface a.
When filter 100 is installed in housing 200, make last pleat 112 away from one end of connecting portion towards air intake surface a, namely between last pleat 112 and adjacent middle pleat 111 opening direction of angle towards air intake surface a.Because two last pleats 112 are not connected with bundle limit 120, mean that last pleat 112 is in loose condition (of surface).In working order, under the effect of the air-flow entered from air intake surface a, end pleat 112 can be expanded to further relative to adjacent middle pleat 111 and contact with housing 200, and that is, two last pleats 112 can launch to the direction away from air intake surface a as free end is lower in working order.
As in background technology, conveniently install, the size of size slightly larger than filter 100 of housing 200 is set usually.After installing, the angle launched under last pleat 112 nature is θ 1, now, also has certain gap D (as Fig. 5) between last pleat 112 and housing 200.
With reference to Fig. 6, when outside air passes filter 100 along wind direction W, the air contacted with last pleat 112 can form certain pressure to last pleat 112, this pressure is applied to the surface of last pleat 112 towards adjacent middle pleat 111, impel last pleat 112 to launch further relative to adjacent middle pleat 111, the angle between last pleat 112 with adjacent middle pleat 111 becomes large until contact with housing 200.Now, the angle between last pleat 112 and adjacent middle pleat 111 is θ 2, θ 2> θ 1.
It should be noted that, if under nature, even if having gap D between last pleat 112 and housing 200, this gap D is also very little, only needs less air-flow that last pleat 112 just can be made to be deformed into and contacts with housing 200.When air-flow increases, the pressure between last pleat 112 and housing 200 also can increase, and makes close contact between last pleat 112 and housing 200, thereby enhances the sealing between filter 100 and housing 200.
In other embodiments, if the angle that last pleat launches in its natural state is enough large, after installing, the end meeting of last pleat and body contact, at this time just do not have above-mentioned gap.So in like manner, under the effect of air-flow, the pressure between last pleat and housing can increase further, makes the contact between last pleat and housing tightr, strengthens the sealing between filter and housing further.
As can be seen here, in the present embodiment, whole last pleat 112 with bundle limit 120 be not connected, last pleat 112 can be launched relative to adjacent middle pleat 111, and can under the effect of air-flow with the close contact of housing 200, increase with housing 200 between sealing.Further, air-flow is larger, and last pleat 112 is tightr with the contact of housing 200, and sealing is stronger.
In the present embodiment, filter core 110 is non-woven fabrics filter core, is compounded with adsorbent in non-woven fabrics filter core, and adsorbent can choose activated carbon etc.
In other embodiments, different according to seal request between filter from housing, also can arrange free end and only have one, be positioned at one end of filter core.
In other embodiments, according to needing last pleat, the requirement of expanded angle is different, can arrange the part that free end is last pleat, and be positioned at last pleat one end away from connecting portion.That is, last pleat, in the one end away from connecting portion, has one section not to be connected with bundle limit.Wherein, free end can be one and be arranged in one of them last pleat, also can be two and lay respectively in two last pleats.
In other embodiments, according to the difference required free end, can arrange in the ruffle at filter core two ends, one end is had at least to have and the unconnected free end in bundle limit, this free end can not only comprise last pleat, also comprises a part for one or more middle pleat or the middle pleat adjacent with last pleat, and two bundle limits are connected with all the other ruffles outside free end, identical with the present embodiment, free end can move relative to all the other ruffles and can launch to the direction away from air intake surface down in working order.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
