Description

Technical Field

[0001] The utility model relates to the technical field of filters, and particularly relates to a high-dust-holding oil-injected air filter. Background Art

[0002] Air filters are mainly used to remove particulate impurities in the air, prevent the air inhaled during the operation of the engine from containing impurities such as dust, and reduce the wear of parts. The structural forms of conventional air filter products are divided into two categories: flat and cylindrical. Among them, the air filter products with a flat structure have a simple structure, are easy to use, and are widely used. However, the existing air filter products with a flat structure have a single function, only have a simple filtering function, do not have a combustion-supporting function, have a low dust-holding capacity, and the filter element of the filter is prone to looseness under the impact of air flow during actual use, thereby resulting in a deterioration of the filtering effect. Therefore, improvement is needed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a high-dust-holding oil-injected air filter, which has a high dust-holding capacity and a good combustion-supporting effect, and the formed filter element has a stable structure and a good anti-impact effect.

[0004] To achieve the above technical solution, the utility model provides a high-dust-holding oil-injected air filter, including: a bottom frame, a bottom net, a formed filter element, and an end-edge shaping frame. The bottom net is fixed on the bottom frame, the formed filter element is installed on the bottom net, and the bottom end edge of the formed filter element is connected to the bottom frame through formed hot melt adhesive. The formed filter element is formed by folding a filter paper with a W shape and evenly sprayed with mineral oil on the surface, and is shaped by a plurality of formed hot melt adhesives at the top and bottom. The middle part of the formed filter element is constrained and shaped by the end-edge shaping frame.

[0005] In the above technical solution, by using a formed filter element formed by folding a filter paper with a W shape and evenly sprayed with mineral oil on the surface and shaped by a plurality of formed hot melt adhesives at the top and bottom, not only can the dust-holding capacity be enhanced, but also when the vehicle is running at high speed / accelerating suddenly, a very small amount of oil molecules on the surface of the formed filter element will enter the engine combustion chamber and fully participate in combustion, thereby improving the combustion effect. By using the end-edge shaping frame to constrain and shape the middle part of the formed filter element, the formed filter element can still maintain its original state under the impact of air flow and maintain the filtering effect.

[0006] Preferably, the bottom net is a metal net, the end edge of the bottom net is fixed on the end edge of the bottom frame, and diamond-shaped mesh holes are evenly distributed on the bottom net. By setting the bottom net, the support for the formed filter element can be strengthened, and the anti-impact ability of the formed filter element can be improved.

[0007] Preferably, two parallel and spaced forming hot melts are pasted on the bottom surface of the formed filter element, and three parallel and spaced forming hot melts are pasted on the top surface of the formed filter element. A side-edge shaping frame is sleeved around the middle of the side surface of the formed filter element. By providing the forming hot melts, on the one hand, the shaping ability of the top and bottom surfaces of the formed filter element can be enhanced, and on the other hand, it is also convenient for docking and installation with external equipment. By sleeving a side-edge shaping frame around the middle of the side surface of the formed filter element, the overall shaping restraint effect on the formed filter element can be enhanced, so that the formed filter element can still maintain its original state under the impact of a strong air flow.

[0008] Preferably, the bottom frame is a PU glue frame.

[0009] The beneficial effects of a high-dust-holding oil-injected air filter provided by the present utility model are as follows: The high-dust-holding oil-injected air filter has a simple structure and a reasonable design, has a high dust-holding capacity and a good combustion-supporting effect, and the formed filter element has a stable structure and a good anti-impact effect. The formed filter element adopts a W-shaped folding structure, and the surface of the formed filter element is evenly sprayed with mineral oil, which is beneficial to the filter element to fully adsorb tiny dust particles in the air during operation, and can fully improve the dust-holding capacity while improving the filtration efficiency; when the vehicle is running at high speed / under sudden acceleration, a very small amount of oil molecules on the surface of the formed filter element will enter the engine combustion chamber and fully participate in combustion, thereby improving the combustion effect. By using a side-edge shaping frame to bind and shape the middle of the formed filter element, the formed filter element can still maintain its original state under the impact of the air flow and maintain the filtering effect.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment: A high-dust-holding oil-injected air filter.

[0018] Refer to Figures 1 to 5 As shown, a high-dust-holding oil-injected air filter includes: a bottom frame 1, a bottom net 2, a formed filter element 3, and an end-edge shaping frame 4. The bottom net 2 is fixed on the bottom frame 1, and the formed filter element 3 is installed on the bottom net 2. The bottom frame 1 is a PU glue frame, and the bottom net 2 is a metal net. The end edges of the bottom net 2 are fixed on the end edges of the bottom frame 1. The bottom net 2 is evenly distributed with diamond-shaped mesh holes. By setting the bottom net 2, the support for the formed filter element 3 can be strengthened, and the impact resistance of the formed filter element 3 can be improved. The formed filter element 3 is formed by folding a filter paper with a W shape and evenly sprayed with mineral oil on the surface, and is shaped by multiple formed hot melt adhesives 5 at the top and bottom. Two parallel and spaced formed hot melt adhesives 5 are pasted on the bottom surface of the formed filter element 3, and three parallel and spaced formed hot melt adhesives 5 are pasted on the top surface of the formed filter element 3. An end-edge shaping frame 4 is sleeved around the middle of the side surface of the formed filter element 3. By setting the formed hot melt adhesives 5, on the one hand, the shaping ability of the top and bottom surfaces of the formed filter element 3 can be enhanced, and on the other hand, it is also convenient for docking and installation with external equipment. By sleeving an end-edge shaping frame 4 around the middle of the side surface of the formed filter element 3, the overall shaping restraint effect on the formed filter element 3 can be enhanced, so that the formed filter element 3 can still maintain its original state under the impact of a strong air flow and maintain the filtering effect.

[0019] This high-dust-holding oil-injected air filter has a simple structure and reasonable design, with a relatively high dust-holding capacity and good combustion-supporting effect. Moreover, the formed filter element 3 has a stable structure and good impact resistance. The formed filter element 3 adopts a W-shaped folding structure, and the surface of the formed filter element 3 is evenly sprayed with mineral oil, which is beneficial to the filter to fully adsorb tiny dust particles in the air during operation, improving the filtering efficiency while fully increasing the dust-holding capacity; when at high speed / rapid acceleration, a very small amount of oil molecules on the surface of the formed filter element 3 will enter the engine combustion chamber and fully participate in combustion, thereby improving the combustion effect. By using the end-edge shaping frame 4 to bind and shape in the middle of the formed filter element 3, the formed filter element 3 can still maintain its original state under the impact of the air flow and maintain the filtering effect.

[0020] The above is the preferred embodiment of the present utility model, but the present utility model should not be limited to the content disclosed in this embodiment and the drawings. Therefore, all equivalent or modified implementations completed without departing from the spirit disclosed by the present utility model fall within the protection scope of the present utility model.
