Abstract
The utility model belongs to the technical field of automobile internal combustion engine parts, and discloses a filter element of an air filter, which comprises an inner support ring and an outer support ring, wherein end covers are arranged at the two ends of the inner support ring and the outer support ring; filter paper is arranged between the inner support ring and the outer support ring; the two end covers are bonded with the filter paper; the end cover positioned at the air outlet end of the filter element of the air filter is an air outlet end cover made of a high-molecular elastic material; the end surface of the air outlet end cover on the side away from the filter paper is provided with a sealing ring which is made of the same material as the air outlet end cover and is integrally formed by injection molding; a support skeleton is arranged in the air outlet end cover. As the air outlet end cover and the sealing ring are integrally formed by injection molding, the sealing ring does not drop from the air outlet end cover, thus the sealing is more reliable, the phenomenon of filtration failure of the air filter is avoided, the processes are reduced, the efficiency is improved, and the cost is lowered; moreover, since the support skeleton is arranged in the air outlet end cover, the strength of the air outlet end cover can be enhanced.
Description
Technical field
The utility model belongs to car combustion engine component technical field, relates in particular to a kind of filtering element for air filter.
Background technique
Filtering element for air filter is an important spare part on internal combustion engine part air filter, internal-combustion engine is in operation process, the air that need to absorb cleanly from the external world, for diesel oil, fully burn, so that outputting power, dirty air enters motor will make diesel combustion abundant not, will reduce emission standard, cause the wearing and tearing of gas engine part simultaneously, make motor generation premature wear, greatly reduce working life; The effect of filtering element for air filter is exactly the dust impurity of guaranteeing in the effective filtered air of air filter energy, make clean air enter motor, guarantee the abundant of diesel combustion, avoid the wearing and tearing of gas engine part simultaneously, thereby extend the working life of internal-combustion engine.
At present, the filtering element for air filter of using on air filter mainly contains two kinds of structural types, a kind of is PU radial seal filter core, another kind is the axial seal filter core that adopts irony end cap, the seal ring of this kind of filtering element for air filter sticks with glue and is connected on irony end cap, bonding not firm the coming off of seal ring that easily cause, cause filtering element for air filter sealing unreliable, air filter filters and lost efficacy, dirty air is entered in motor, cause the wearing and tearing of gas engine part, greatly reduce the working life of motor; On irony end cap, adhering and sealing circle need to adopt multiple working procedure to complete in addition, and efficiency is low, and cost is high.
Model utility content
Technical problem to be solved in the utility model is: a kind of filtering element for air filter is provided, to solve adhering and sealing circle on the irony end cap of conventional axial sealing air filter element, easily comes off, and the technical problem that operation is many, efficiency is low, cost is high.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Filtering element for air filter, comprise inner support circle and outer support circle, the two ends of described inner support circle and outer support circle are equipped with end cap, between described inner support circle and outer support circle, be provided with filter paper, described in two, end cap is connected with described filter paper is bonding, being positioned at the give vent to anger end cap of one end of described filtering element for air filter is the end cap of giving vent to anger that macromolecular material is made, the described end cap of giving vent to anger is provided with seal ring identical with described outlet side cover material and integrated injection molding on the end face away from described filter paper one side, described in the give vent to anger inside of end cap be provided with support frame.
As a kind of improvement, described support frame is provided with some mesh.
As a kind of improvement, described support frame is annular slice structure, the surface of described support frame with described in the give vent to anger end face of end cap parallel.
As a kind of improvement, described in give vent to anger end cap be that PU glue material is made, with the PU glue end cap of seal ring integrated injection molding.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because filtering element for air filter comprises inner support circle and outer support circle, the two ends of inner support circle and outer support circle are equipped with end cap, between inner support circle and outer support circle, be provided with filter paper, two end cap is connected with filter paper is bonding, being positioned at the give vent to anger end cap of one end of filtering element for air filter is the end cap of giving vent to anger that macromolecular material is made, the end cap of giving vent to anger is provided with seal ring identical with outlet side cover material and integrated injection molding on the end face away from filter paper one side, therefore seal ring can not cover and come off from outlet side, filtering element for air filter sealing is more reliable, there will not be air filter to filter the phenomenon losing efficacy, give vent to anger in addition end cap and seal ring integrated injection molding, compare with traditional irony end cap adhering and sealing circle, reduced production process, improved efficiency, also reduced cost, inside due to the end cap of giving vent to anger is provided with support frame again, can increase the intensity of the end cap of giving vent to anger, and the filter paper bonding with the end cap of giving vent to anger is not easy to come off.
Because support frame is provided with some mesh, support frame is annular slice structure, and the surface of support frame parallels with the end face of the end cap of giving vent to anger, and macromolecular material can inside and outside penetrate, be fused into one with support frame, further increase intensity and the bonding reliability of filter paper of the end cap of giving vent to anger.
Due to be positioned at filtering element for air filter give vent to anger the end cap of one end be that PU glue material is made, with the PU glue end cap of seal ring integrated injection molding, PU glue end cap is lightweight, good airproof performance, the better effects if bonding with filter paper, filter paper is not easy to come off from PU glue end cap, has extended the working life of filtering element for air filter.
