Abstract
The invention belongs to the technical field of a car and particularly relates to a car air filter. The technical scheme is that the car air filter comprises an inner layer screen net and an outer layer screen net; a foldable filtering paper layer is arranged between the inner layer screen net and the outer layer screen net; a non-woven fabric filtering layer is arranged at the inner side of the filtering paper layer; and an active carbon layer is arranged between the filtering paper layer and the inner layer screen net. The active carbon layer is arranged between the filtering paper layer and the inner layer screen net so that a blocking phenomenon of the filtering paper layer is reduced and the filtering effect is improved. The invention provides the car air filter with the good filtering effect.
Description
Technical field
The invention belongs to automobile technical field, particularly relate to air filter for automobile.
Background technique
At present, air-strainer is mainly used in the fields such as pneumatic machinery, diesel machine, and effect is the air that cleaning is provided for these machinery, in case these machinery suck the probability that increases abrasion and damage with the air of impurity particle at work.The job requirement of air-strainer is to bear high efficiency air filtering work, do not increase too much resistance for Air Flow, and the energy long time continuous working, there is filter paper layer in existing air filter for automobile, and filter paper layer is easy to be blocked by impurity after using a period of time.
Summary of the invention
Technical problem to be solved is to overcome the defective that prior art exists, provide a kind of good filtration effect air filter for automobile.
The technology used in the present invention solution comprises nexine silk screen and outer silk screen, is provided with folding filter paper layer between nexine silk screen and the outer silk screen, and the inboard of filter paper layer is provided with the nonwovens filter layer, is provided with active carbon layer between filter paper layer and the nexine silk screen.
Compared with prior art, the beneficial effect that the present invention has is: the present invention is by arranging active carbon layer between filter paper layer and nexine silk screen, the choking phenomenon of the filter paper layer of slowing down has improved filtering effect.
Description of drawings
Fig. 1 is structure diagram of the present invention.
Among the figure:
1, nexine silk screen, 2, filter paper layer, 3, the nonwovens filter layer, 4, outer silk screen, 5, active carbon layer.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, air filter for automobile comprises nexine silk screen 1 and outer silk screen 4, is provided with folding filter paper layer 2 between nexine silk screen 1 and the outer silk screen 4, the inboard of filter paper layer 2 is provided with nonwovens filter layer 3, is provided with active carbon layer 4 between filter paper layer 2 and the nexine silk screen 1.
