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 up 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, this elastomeric material long-time high temperature oil invade bubble perishable distortion down, hardness and other performances also can change, through after the cold cycling repeatedly, the sealing reduction of rubber.Oil leakage phenomenon takes place easily.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem that the present invention will solve provides a kind of cleaner of good sealing effect.
For this reason; The present invention adopts following technical scheme to realize: a kind of filter element, comprise end cap, filter paper and sealing ring, and said end cap scalds the two ends of knot at filter paper; Said end cap is provided with sealing ring, it is characterized in that said sealing ring adopts nonwoven cloth material to process; Be provided with wavy impression above said end cap and the nonwoven weld, said nonwoven is provided with wavy impression, the said wavy circular arrangement on the said nonwoven that is stamped in; The present invention also can said end cap end face be provided with wavy groove, said waveform groove circular arrangement on the end face of said end cap; Said nonwoven cloth material adopts the ultrasonic bonding mode to be bonded on the said 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 not firm problem of welding that the solder side injustice causes has prolonged life of product and the percent defective that reduces in the process more.

The specific embodiment
With reference to accompanying drawing, this filter element comprises end cap 2, filter paper 1, central tube 5 and sealing ring 3; Said central tube 5 places in the filter paper 1, and said end cap 2 scalds the two ends of knot at filter paper 1 and central tube 5, is provided with said sealing ring 3 in the central hole of said end cap 2; Said sealing ring 3 adopts nonwoven cloth materials to be welded on the said end cap 2 by ultrasonic welding process, adopt this nonwoven cloth material after, it is corrosion-resistant to have improved much than the rubber in the tradition with resistance to elevated temperatures; And receive can not be out of shape under the corrosion of high temperature oil; Keep 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 said end cap, the mode of its processing has two kinds, and a kind of is that said 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 said end cap 2; This wavy groove 4 also circumference on said end cap 2; Nonwoven also is close to end cap 2 after by ultrasonic bonding; This dual mode can solve owing to solder side is uneven and produce nonwoven and the not firm problem of end cap 2 welding, has prolonged life of product and the percent defective that reduces in the process more.
Claims (1)
1. filter element; Comprise end cap (2), filter paper (1) and sealing ring (3), said end cap scalds knot at the two ends of filter paper (1), and said end cap (2) is provided with sealing ring (3); Said sealing ring (3) adopts nonwoven cloth material to process; It is characterized in that said nonwoven cloth material adopts the ultrasonic bonding mode to be welded on the said end cap (2), said nonwoven is provided with wavy impression, the said wavy circular arrangement on the said nonwoven that is stamped in; Or the end face of said end cap (2) is provided with wavy groove, said wavy groove circular arrangement on the end face of said end cap (2).
