Abstract
The utility model discloses an oil filter. The oil filter comprises a filter part and is characterized in that the filter part comprises two layers of filter paper cores in interface fit with each other. The end surfaces of the two layers of filter paper cores, on the opposite sides thereof, are respectively provided with a plurality of semi-spherical bumps. The semi-spherical bumps are uniformly arranged on the end surfaces of the filter paper cores. According to the technical scheme of the utility model, the oil filter is larger in the filtering area of the filter paper cores, so that the filtering accuracy is improved.
Description
Technical field
The utility model relates to a kind of auto parts machinery, and more particularly, it relates to a kind of oil filter.
Background technique
At present, known filter element consists of upper and lower end cap, filter cylinder and center tube and other auxiliary component, its filter cylinder is along circumference, become some plane foldings and form on center tube by filter paper core, and the important performances such as the resistance of filter cleaner flow and working life are directly relevant with filter paper core.In known technology, above-mentioned folding is flat, if the folding of this flat is too much in order to increase filter area folding number on the circumference of center tube, squeezes overstockedly, can increase on the contrary the resistance of machine oil.And current often some supporting producer and client require under identical specification, make the filter cleaner that filter area is large, with cost-saving, so under same size, rely on increase folding number to increase filter area and be difficult to accomplish.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of oil filter that improves filter paper core filter area, reaches the object that improves filter precision.
For achieving the above object, the utility model provides following technological scheme: a kind of oil filter, comprise filter house, described filter house comprises the two-layer filter paper core that gap arranges that is, the relative side end face of described two-layer filter paper core is provided with some hemispherical projections, and described hemispherical projection is evenly arranged on filter paper core end face.
By adopting technique scheme, be provided with on the opposing end surface of two-layer filter paper core and two-layer filter paper core and be provided with some hemispherical projections, described hemispherical projection has improved the filter area of filter paper core, machine oil enters oil filter inside and need to filter through the hemispherical projection filtration of first layer filter paper core and the hemispherical projection of second layer filter paper core from outside, when improving filter area, also increased filtration number of times, improve in all its bearings the filter precision of this oil filter, reduced the content that machine oil enters impurity in automobile.
The utility model is further set to: the hemispherical projection on described two-layer filter paper core mutually conflict arrange and described arbitrary filter paper core on the summit of hemispherical projection on the gap between two hemispherical particles of another filter paper core.
By adopting technique scheme, the setting of mutually conflicting of the hemispherical projection of two-layer filter paper core, make the structure of this filter house compacter, and in two-layer filter paper core wherein the hemispherical projection on one deck be plugged in the gap between two hemispherical projection of another layer, so design can prevent some local smaller situations of filter area filter area larger and other ground of this filter house, guarantees that each local filter precision of this filter house is identical.
The utility model is further set to: the filter precision that is positioned at outer field filter paper core is less than the filter precision of the filter paper core that is positioned at internal layer.
By adopting technique scheme, make inside and outside two-layer filter precision different, carry out stepped filtration, can improve the rate of filtration, avoid because outer filter precision is too high, making the too slow situation of the machine oil rate of filtration, and can reduce production costs like this.
Accompanying drawing explanation

Fig. 2 is the utility model oil filter embodiment's A portion enlarged view.
Drawing reference numeral explanation:
1, filter house; 11, filter paper core; 12, hemispherical projection.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model oil filter embodiment is described further.
A kind of oil filter, comprise filter house 1, described filter house 1 comprises the two-layer filter paper core 11 that gap arranges that is, and the relative side end face of described two-layer filter paper core 11 is provided with some hemispherical projections 12, and described hemispherical projection 12 is evenly arranged on filter paper core 11 end faces.
By adopting technique scheme, be provided with on the opposing end surface of two-layer filter paper core 11 and two-layer filter paper core 11 and be provided with some hemispherical projections 12, described hemispherical projection 12 has improved the filter area of filter paper core 11, machine oil enters oil filter inside and need to filter through hemispherical projection 12 filtrations of first layer filter paper core 11 and the hemispherical projection 12 of second layer filter paper core 11 from outside, when improving filter area, also increased filtration number of times, improved in all its bearings the filter precision of this oil filter, reduced the content that machine oil enters impurity in automobile.
The summit of the mutual hemispherical projection 12 on setting and described arbitrary filter paper core 11 of conflicting of hemispherical projection 12 on described two-layer filter paper core 11 is on the gap between two hemispherical particles of another filter paper core 11.
By adopting technique scheme, the hemispherical projection 12 of two-layer filter paper core 11 is mutually conflicted and is arranged, make the structure of this filter house 1 compacter, and in two-layer filter paper core 11 wherein the hemispherical projection 12 on one deck be plugged in the gap between two hemispherical projection 12 of another layer, so design can prevent this filter house 1 some local smaller situations of filter area filter area larger and other ground, guarantees that this filter house 1 each local filter precision is identical.
The filter precision that is positioned at outer field filter paper core 11 is less than the filter precision of the filter paper core 11 that is positioned at internal layer.
By adopting technique scheme, make inside and outside two-layer filter precision different, carry out stepped filtration, can improve the rate of filtration, avoid because outer filter precision is too high, making the too slow situation of the machine oil rate of filtration, and can reduce production costs like this.
