Abstract
Noiseless car air filter. Because filter paper compresses at vertical easy stretch, the scraps of paper of traditional car air filter filter core filter paper in the use can be tremble because of different production of air volume to produce great sound, this brings the unnecessary noise for the vehicle in traveling, influences driver's driving environment, easily covers other sound that produce simultaneously in the car. The utility model discloses constitute filter paper (1) including the rectangle, filter paper and polyurethane foam sealed frame (2) be connected filter paper with the sealed frame of polyurethane foam between be provided with and prevent supporting network (3) of filter paper shrink. The utility model discloses be applied to car air filter.
Description
Technical field：
This utility model is related to a kind of noiseless car air filtering core.
Background technology：
As filter paper is in the easily stretchable compression in longitudinal direction, the scraps of paper of traditional car air filtering core filter element filter paper in use
Can be because the different of ventilation produce shake, so as to produce larger sound, this brings unnecessary making an uproar to the vehicle in traveling
Sound, affects the driving environment of driver, while easily covering other sound of in-car generation.
Utility model content：
The purpose of this utility model is to provide a kind of noiseless car air filtering core.
Above-mentioned purpose is realized by following technical scheme：
A kind of noiseless car air filtering core, its composition include：The filter paper of rectangle, described filter paper are close with polyurethane foam
Envelope frame connection, being provided between described filter paper and described polyurethane foam sealing frame prevents propping up for described filter paper contraction
Support net.
Described noiseless car air filtering core, the surrounding of described supporting network are fixed in polyurethane foam sealing frame,
Described supporting network is iron net or plastic wire, described iron net 0.2 ~ 0.8mm of thickness.
Described noiseless car air filtering core, described filter paper are pasted with filter cotton.
The beneficial effects of the utility model：
1. the supporting network of this noiseless car air filtering core is attached to its surface, as supporting network has certain rigidity,
So as to prevent filter paper and polyurethane foam sealing frame from shrinking.
The manufacture method of this noiseless car air filtering core is as described below：First supporting network is layered on filter paper, is then placed
The mould of sealing frame, then polyurethane foam is poured into, so as to form polyurethane foam sealing frame.Polyurethane foam sealing frame will be supported
Four sides of net and filter paper be adhesively fixed so that the every a piece of scraps of paper of filter paper are firmly glued with polyurethane foam sealing frame respectively
Close, the compressional stiffness of polyurethane foam sealing frame is strengthened, so as to enhance deformation resistance of the filter paper per a piece of scraps of paper, when logical
When air quantity changes, as two ends of the filter paper per a piece of scraps of paper are fixed, the possibility of sounding is shaken so as to substantially reduce the scraps of paper
Property so that air filtering core no longer produces noise.
Description of the drawings：
Accompanying drawing 1 is main sectional view of the present utility model.
Accompanying drawing 2 is top view of the present utility model.
Specific embodiment：
Embodiment 1：
A kind of noiseless car air filtering core, its composition include：The filter paper 1 of rectangle, described filter paper and polyurethane foam
Sealing frame 2 connects, and being provided between described filter paper and described polyurethane foam sealing frame prevents described filter paper from shrinking
Supporting network 3.
Embodiment 2：
Noiseless car air filtering core according to embodiment 1, the surrounding of described supporting network are fixed on polyurethane and send out
In bubble sealing frame, described supporting network is iron net or plastic wire, described iron net 0.2 ~ 0.8mm of thickness.
Embodiment 3：
Noiseless car air filtering core according to embodiment 1 or 2, described filter paper are pasted with filter cotton 4.
Claims (1)
1. a kind of noiseless car air filtering core, its composition include：The filter paper of rectangle, is characterized in that：Described filter paper and poly- ammonia
Ester foaming sealing frame connects, and being provided between described filter paper and described polyurethane foam sealing frame prevents described filter paper
The supporting network of contraction, polyurethane foam sealing frame is by four sides of supporting network and filter paper be adhesively fixed so that filter paper it is every
The a piece of scraps of paper respectively with polyurethane foam sealing frame good bond；
The surrounding of described supporting network is fixed in polyurethane foam sealing frame, and described supporting network is iron net or plastic wire, institute
Iron net 0.2 ~ the 0.8mm of thickness for stating；
Described filter paper is pasted with filter cotton.
