As preferably, between the internal face of described housing oil outlet tube one end in housing and bottom end face, chamfering connects.Be convenient to assembling.
As preferably, between described projection and end cover of filter element boss, seamlessly transit.Convenient formation, is easy to assembling, can increase the surface of contact with inner walls face, good sealing effect.
As preferably, described housing and housing oil outlet tube are structure as a whole.Convenient formation, simple in structure.
As preferably, described housing oil outlet tube comprises vertical section and horizontal segment, and described vertical section is positioned at housing and bottom and the socket of end cover of filter element boss, described horizontal segment run through housing inside and outside and its be positioned at one end of housing and be connected with top vertically section.
As preferably, between the internal face of described through hole and top end, seamlessly transit.
As preferably, described housing oil outlet tube inwall is provided with a circle step surface, and the diameter that described housing oil outlet tube is positioned at the above part of step surface equals through hole internal diameter, and described end cover of filter element boss is against on step surface after being sheathed in housing oil outlet tube.
Beneficial effect:
The diesel-oil filter that the present invention adopts technique scheme to provide, end cover of filter element boss and housing oil outlet tube are embedded assembly structure, can eliminate the flow resistance of fuel oil in filter element filtering process, thereby improve the filter efficiency of fuel oil, by being set, projection coordinates good airproof performance with housing oil outlet tube.

Embodiment
As shown in Figures 1 to 3, a kind of diesel-oil filter, comprise housing 1 and be located at the filter core in housing 1, wherein, filter core comprises end cover of filter element 21 and is located at the filter paper 22 of end cover of filter element 21 bottoms, end cover of filter element 21 end faces have end cover of filter element boss 211, end cover of filter element 21 is provided with through hole 212, through hole 212 runs through end cover of filter element boss 211, housing 1 is provided with and is communicated with the inside and outside housing oil outlet tube 11 of housing 1, housing oil outlet tube 11 is positioned at one end and 211 sockets of end cover of filter element boss of housing 1, end cover of filter element boss 211 is sheathed in housing oil outlet tube 11, end cover of filter element boss 211 outer wall have around the end cover of filter element boss projection of 211 1 weeks 213, inwall respective protrusions 213 places of housing oil outlet tube 11 have around the housing oil outlet tube groove of 11 1 weeks 111, described protruding 213 are embedded in groove 111, and interference fit between the two, be designed to boss groove embedded structure, can make fuel oil in filter flowing process, end cap boss inwall is produced to certain pressure, thereby end cap boss is outwards expanded, cause the assembling between end cap boss and housing oil outlet tube to form interference fit, thereby its better tightness, between the internal face of housing oil outlet tube 11 one end in housing 1 and bottom end face, chamfering connects, between projection 213 and end cover of filter element boss 211, seamlessly transit, moulding and assembling are all more convenient, housing 1 and housing oil outlet tube 11 adopt integrative-structure, its middle shell oil outlet tube 11 is comprised of vertical section 112 and horizontal segment 113, vertically section 112 is positioned at housing 1 and bottom and 211 sockets of end cover of filter element boss, horizontal segment 113 runs through inside and outside housing and its one end that is positioned at housing is connected with the top of vertical section 112, rational in infrastructure, be easy to moulding, be convenient to assembling.The present invention becomes embedded by end cover of filter element boss with the assembly structure design of housing oil outlet tube, during assembling filter core, end cover of filter element boss is embedded in housing oil outlet tube, both can reduce the resistance of runner, can strengthen again the sealing of filter core and the assembling of housing oil outlet tube, assembly structure is simple, good sealing effect, the resistance little (Fig. 1 direction of arrow represents fuel flow direction) of fuel flow, and filter efficiency is high.
As shown in Figure 4, between through hole 212 internal faces and top end, seamlessly transit.Adopt after this structure, the joint of end cover of filter element boss 211 and housing oil outlet tube 11 seamlessly transits, and when fuel oil flows through the joint of end cover of filter element boss 211 and housing oil outlet tube 11, whirlpool can not occur, and flow effect is good.Vertically between section 112 and horizontal segment 113, also can adopt round-corner transition.
Embodiment two:
As shown in Figure 5, be with embodiment one difference, housing oil outlet tube 11 inwalls are provided with a circle step surface 114, and end cover of filter element boss 211 is sheathed on housing oil outlet tube 11 and is against on step surface 114 after interior, and the diameter that housing oil outlet tube 11 is positioned at more than 114 part of step surface equals through hole 212 internal diameters.Adopt after this structure, the diameter that is positioned at more than 114 part of step surface due to housing oil outlet tube 11 equals through hole 212 internal diameters, and fuel oil had not both had resistance while flowing through the two joint, again whirlpool can occur, and flow effect is good, and the filter efficiency of fuel oil is high.
