Description
Technical field
The utility model relates to a kind of filter cleaner, particularly with a kind of gasoline filter.
Background technique
The effect of gasoline filter is with moisture in the gasoline and impurity filtering.Fuel oil gets into through oil inlet pipe in the sediment bowl of filter cleaner under the effect of petrol pump during engine operation.Because this moment, volume became big, flow velocity diminishes, and than the bottom that the heavy water of oil and impurity particle just are deposited in cup, light impurity flows to filter core with fuel oil, and the fuel oil of cleaning flows out through oil pipe from the inside that the micropore of filter core oozes people's filter core then.
At present, the gasoline filter that occurs on market and the data includes shell, and an axial end of shell is provided with end cap; The other end is provided with oil outlet, offers filler opening on the end cap, is provided with filtering cavity between its filler opening and the oil outlet; Be provided with filter core in the filtering cavity, be provided with spring between the oil outlet of shell and the filter core, usually; Oil outlet and filler opening place can be provided with the oil pipe of drainage respectively, with being connected of these convenient and car interior-exterior portion parts.Yet; Often be connected between oil pipe and the shell at present traditional gasoline filter through screw or link enforcement, above-mentioned Placement is just arranged after, need the joint of oil pipe and shell be sealed; Not only make the structure of gasoline filter become complicated; Be unfavorable for assembling, the seal point on the shell is too much, and sealing can not get guaranteeing.
Summary of the invention
To the deficiency that existing technology exists, the utility model provides the gasoline filter of a kind of good airproof performance, compact structure.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of gasoline filter includes shell; An axial end of shell is provided with end cap, and the other end is provided with oil outlet, offers filler opening on the end cap; Be provided with filtering cavity between its filler opening and the oil outlet, be provided with filter core in the filtering cavity, be provided with spring between the oil outlet of shell and the filter core; The oil outlet of shell and filler opening place are provided with oil inlet pipe and oil outlet tube respectively; It is characterized in that: the joint of said shell and end cap is provided with draw-in groove, and the edge card of end cap is located in this draw-in groove, and the middle part of end cap is towards the filtering cavity indent; Filler opening is the hole that the confession oil inlet pipe offered of interior recess inserts, between the outer circumferential face of oil inlet pipe and the hole through being welded to connect; The outer circumferential face of said oil outlet tube and the oil outlet of shell are and are welded to connect.
Adopt technique scheme; Oil inlet pipe and oil outlet tube adopt the mode of welding to be connected with end cap and shell, and after being provided with like this, the joint of oil inlet pipe and oil outlet tube and shell and end cap both can keep sealing; And installation is comparatively convenient; Need not to establish in addition other Sealing, reduced component, also reduced cost of production simultaneously in the joint of oil inlet pipe and oil outlet tube and end cap and shell.
The utility model further is set to: oil inlet pipe and oil outlet tube are provided with the dust cover that removably connects with respect to the other end place that is connected an end with filler opening and oil outlet.
Adopt technique scheme, the setting of dust cover can prevent that dust from being entered in the filtering cavity by oil inlet pipe or oil outlet tube place, and characteristics are applicable in transportation process.
The utility model further is set to: end cap is provided with Sealing, and the sealing part includes to press is located at the sealing gasket that reaches between end cap and the filter core between filter core and the spring.
Adopt technique scheme, after being provided with like this, sealing gasket receives the pressure of spring and conflicts, and has improved sealability.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
