Abstract
The invention discloses a filter element which comprises an end closure (2), a filter paper (1), and a sealing ring (3). The end closure is connected on the two ends of the filter paper (1) in a hot way. The end closure (2) is provided with the sealing ring (3). The filter element is characterized in that the sealing ring (3) is made of non-woven fabric. The sealing ring made of non-woven fabric solves the problems that a rubber sealing ring is not resistant to high temperature and rusty in the traditional technology; the filter element has good sealing effect and simple manufacturing technique.
Description
Technical field
What the present invention relates to is the filter element that uses on a kind of motor vehicle, belongs to the motor vehicle fittings field.
Background technology
At present, the use amount of filter element is very big, basically, the structure of filter element is made of filter paper, central tube, end cap seal circle, central tube places in the filter paper, and end cap scalds knot at the two ends of filter paper, in conventional art, all be at the centre bore position of end cap sealing ring to be set, this sealing ring also adopts elastomeric material to make.When making, use special-purpose mould moldings formed therefrom, manufacture craft is comparatively complicated.And, the perishable distortion under the bubble of invading in long-time high temperature oil of this elastomeric material, hardness and other performances also can change, and through after the cold cycling repeatedly, the sealing of rubber reduces.Oil leakage phenomenon takes place easily.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved in the present invention provides a kind of cleaner of good sealing effect.
For this reason, the present invention realizes by the following technical solutions: a kind of filter element, comprise end cap, filter paper and sealing ring, and described end cap scalds the two ends of knot at filter paper, described end cap is provided with sealing ring, it is characterized in that described sealing ring adopts nonwoven cloth material to make; Be provided with wavy impression above described end cap and the nonwoven weld, described nonwoven is provided with wavy impression, the described wavy circular arrangement on the described nonwoven that is stamped in; The present invention also can described end cap end face be provided with wavy groove, described waveform groove circular arrangement on the end face of described end cap; Described nonwoven cloth material adopts the ultrasonic bonding mode to be bonded on the described end cap.
Among the present invention, after its sealing ring adopts nonwoven cloth material to be connected on the end cap with supersonic welding, the flexibility of nonwoven, corrosion-resistant and resistance and high temperature resistance property, and the characteristics that can not be out of shape, its sealing property and service life are greatly improved than the rubber seal in the tradition.The wave impression is set on nonwoven, perhaps after wavy groove is set on the end cap, can solves when ultrasonic bonding because the problem of the not prison welding that the solder side injustice causes has prolonged the percent defective in life of product and the reduction process more.

The specific embodiment
With reference to accompanying drawing, this filter element, comprise end cap 2, filter paper 1, central tube 5 and sealing ring 3, described central tube 5 places in the filter paper 1, described end cap 2 scalds the two ends of knot at filter paper 1 and central tube 5, central hole at described end cap 2 is provided with described sealing ring 3, described sealing ring 3 adopts nonwoven cloth material to be welded on the described end cap 2 by ultrasonic welding process, after adopting this nonwoven cloth material, its corrosion-resistant and resistance to elevated temperatures has improved much than the rubber in the tradition, and is subjected to can not be out of shape under the corrosion of high temperature oil, keeps original performance, reduced the weight of whole cleaner simultaneously, and technology is very simple.Among the present invention, when being welded on nonwoven on the described end cap, the mode of its processing has two kinds, and a kind of is that described nonwoven is provided with wavy impression 4, this wavy impression 4 circular arrangement on nonwoven; So after pushing down wavy impression 4 with ultrasonic broken welding, the point corresponding position, peak with wavy impression on its end cap 2 just forms indenture, makes nonwoven be close to end cap 2; Another kind of mode is that wavy groove 4 is set on described end cap 2, this wavy groove 4 also circumference on described end cap 2, nonwoven also is close to end cap 2 after by ultrasonic bonding, this dual mode can solve owing to the uneven problem that produces nonwoven and end cap 2 not prison weldings of solder side, has prolonged the percent defective in life of product and the reduction process more.
Claims (4)
1, a kind of filter element comprises end cap (2), filter paper (1) and sealing ring (3), and described end cap scalds knot at the two ends of filter paper (1), and described end cap (2) is provided with sealing ring (3), it is characterized in that described sealing ring (3) adopts nonwoven cloth material to make.
2, filter element according to claim 1 is characterized in that described nonwoven is provided with wavy impression (4), described wavy impression (4) circular arrangement on described nonwoven.
3, according to the described filter element that gets of claim 1, it is characterized in that the end face of described end cap (2) is provided with wavy groove (4), described waveform groove (4) circular arrangement on the end face of described end cap (2).
4, according to claim 1
-3 any one described cleaner is characterized in that described nonwoven cloth material adopts the ultrasonic bonding mode to be welded on the described end cap (2).
