For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The structural representation of a kind of fuel filter that Fig. 2 provides for the utility model embodiment, Fig. 3 is the structural representation of center tube shown in Fig. 2.As shown in Figures 2 and 3, described fuel filter comprises filter bowl, and filter bowl is mainly comprised of housing 1 and housing gland 2, is provided with filter core 3 in described filter bowl, and the center portion of filter core 3 hollows place is provided with center tube 5, and center tube 5 is provided with the hole 51 of passing through for fuel oil.
By the place, center portion in filter core 3 hollows, center tube 5 is set, can effectively improves filter core 3 and easily towards center, produce the problem of inner side depression.This be because current filter core normally papery or nonwovens, the strength and stiffness of self are less, in the center of filter core 3, arrange after center tube 5, by the matching relationship of filter core 3 and center tube 5, can improve bulk strength and the rigidity of filter core 3, and center tube 5 arranges the inner side of filter core 3, the possibility of therefore having avoided filter core 3 to cave in to the inside.And, on center tube 5, be provided with the hole 51 of passing through for fuel oil, so center tube 5 is when improving filter core 3 strength and stiffness, can also meet the requirement that fuel oil is passed through smoothly.
After in use core barrel 5 improves the strength and stiffness of filter cores 3, can make fuel filter within the longer time in normal operating condition, thereby make the replacing time shorten of fuel filter, this has improved the overall quality of vehicle.Especially more applicable for top-of-the-range version, this is because not only the core component of top-of-the-range version (as motor) need to have higher quality, its detailed design, especially some important accessory (as fuel filter) designs more will meet the configuration of top-of-the-range version, so that these accessories can with core component fit, thereby core component is played a role better.
In the present embodiment, center tube 5 can be made of metal, for example, by sheetmetal, made.During making, can first on metal plate, make hole 51, guarantee that on the basis of center tube 5 self strength and stiffness, the size in hole 51 is the bigger the better, the quantity in hole 51 is The more the better, to guarantee preferably the circulation of fuel oil; Then the flat board that is shaped with hole 51 is curled into tubular, can obtain the center tube 5 in the present embodiment.
Particularly, while using metal to make center tube 5 in the present embodiment, can select electrolytic tinplate or electrolytic galvanized sheet, thereby improve the corrosion resistance of center tube to fuel oil.Conventionally, the thickness of metal center pipe can be between 0.5mm to 0.6mm.
Or in the present embodiment, center tube 5 can also be made of plastics, for example, use rigid plastics to make, to guarantee the strength and stiffness of center tube 5.Because rigid plastics is not flexible, while therefore specifically making, can adopt the method for injection moulding that hole 51 and the tube wall one of center tube 5 are made.The thickness of plastics center tube also can be between 0.5mm to 0.6mm.And for metal, plastics can be better to the corrosion resistance of fuel oil.
In order to strengthen better the strength and stiffness of filter core 3, can the gap between filter core 3 and center tube 5 be arranged smallerly, be for example between 0.5-2mm.This gap is less, and the laminating meeting between filter core 3 and center tube 5 is tightr, thereby can be more obvious to the enhancing effect of the strength and stiffness of filter core 3.
In a modified embodiment of the present utility model, specifically refer again to shown in Fig. 2, one end of filter core 3 (state shown in Fig. 2 lower time be upper end) pressing has upper end cap 6, as shown in Figure 4, the outer periphery of upper end cap 6 are provided with radially towards outside a plurality of the first flanges 61 that extend of described upper end cap, and the plurality of the first flange 61 is uniformly distributed along the outer periphery of upper end cap 6.After in the filter core pressing together 3 is encased in to filter bowl together with upper end cap 6, the first flange 61 on upper end cap 6 has almost contacted, has reduced the gap between upper end cap 6 and housing 1 sidewall with the sidewall of housing 1, so that restriction filter core 3 tilts towards housing 1, add the restriction of 5 pairs of filter cores 3 of center tube, therefore can be from outside and inner two mounting points that aspect limits filter core 3, be that the first flange 61 and 5 pairs of filter cores 3 of center tube on upper end cap 6 have formed the form that outer inner clip is forced, thereby guaranteed the axial direct dimension of filter core 3.
As shown in Figure 4, the structural type of the first flange 61 can be for trapezoidal, and the outer side of trapezoidal like this first flange 61 and the sidewall of housing 1 can form that line contacts or face contact, thereby make the restriction effect of filter core 3 axial direct dimensions better, is also convenient to make simultaneously.
Further, refer again to shown in Fig. 2, the other end of filter core 3 (state shown in Fig. 2 lower time be lower end) pressing has lower end cap 7, the outer periphery of lower end cap 7 are provided with radially towards outside a plurality of the second flanges 71 that extend of described lower end cap, and a plurality of the second flanges 71 are uniformly distributed along the outer periphery of described lower end cap.Equally, the second flange 71 also can be for trapezoidal.The second flange 71 also can guarantee the axial direct dimension of filter core 3 together with center tube 5.But with the first flange 61 differences be the axial direct dimension on the first flange 61 principal security filter core 3 tops, and the axial direct dimension of the second flange 71 principal security filter core 3 bottoms.Like this, by the acting in conjunction of the first flange 61 and the second flange 71, can guarantee the axial direct dimension of filter core 3 in the whole short transverse shown in Fig. 2.
