Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an air filter with a high-dust-holding flow channel. Background Art

[0002] Air filters are mainly used to remove particulate impurities in the air, prevent the air inhaled during engine operation from containing impurities such as dust, and reduce the wear of parts. The structural forms of conventional air filter products are divided into two major 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 applied. However, the filter element of the existing air filter with a flat structure is generally made of folded filter paper, and no special design is made for the flow channel of the filter element. The filtering effect and dust-holding capacity are both average. Since the dust-holding capacity is small, the service life will be reduced, so improvement is needed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an air filter with a high-dust-holding flow channel. Through the structural design of the air flow channel in the filter element, the dust-holding capacity and filtering effect of the filter element can be enhanced, and thus the service life of the air filter can be improved.

[0004] To achieve the above technical solution, the utility model provides an air filter with a high-dust-holding flow channel, including: a bottom frame, a bottom net, and a high-dust-holding filter element. The bottom net is fixed on the bottom frame, the high-dust-holding filter element is installed on the bottom net, the high-dust-holding filter element is made of folded filter paper, and multiple rows of outer bulges or inner bulges are arranged at intervals in the up-and-down direction along the Z-axis on the high-dust-holding filter element, and the outer bulges and inner bulges are arranged in a staggered manner at intervals along the X-axis.

[0005] In the above technical solution, during actual processing, a runway-shaped bubble folding roller die arranged regularly is used to press raised indentations on the flat filter paper. After the filter paper is formed, the raised inner bubbles and outer bubbles are connected in the reverse direction every time to support the gaps between each layer of filter paper, so that a normal air flow channel is formed between each column of bubbles and each row of bubbles. When the air filter is working, air smoothly enters from the intake surface and sequentially passes through the filter paper, outer bubbles, filter paper, outer bubbles, filter paper, or sequentially passes through the filter paper, inner bubbles, filter paper, inner bubbles, filter paper, so that dust or impurities in the air cover the surface of the filter paper as much as possible (that is, the effective filtering utilization rate of the filter paper is as high as possible), thereby effectively improving the dust-holding capacity of the filter paper and ensuring a higher service life of the air filter. In addition, the staggered raised inner bubbles and outer bubbles pressed on the filter paper also play a role in strengthening the stiffness of the filter paper, so that the filter element has a stronger wind resistance effect.

[0006] Preferably, two parallel and spaced setting shaping hot melts are pasted on the bottom surface of the high-dust-holding filter element, and two parallel and spaced setting sealing hot melts are pasted on the top surface of the high-dust-holding filter element. By setting the shaping hot melts and the sealing hot melts, on the one hand, the shaping ability of the top and bottom surfaces of the high-dust-holding filter element can be enhanced, and on the other hand, it is also convenient for the docking and sealing installation with external equipment.

[0007] Preferably, the bottom net is a metal net, the end edges of the bottom net are fixed on the end edges of the bottom frame, and diamond-shaped mesh holes and rectangular bosses are evenly distributed on the bottom net. By setting the bottom net, the support for the high-dust-holding filter element can be strengthened and the shielding of the filter element by the bottom net can be reduced, thereby improving the impact resistance and air passing capacity of the high-dust-holding filter element.

[0008] Preferably, the bottom frame is a PU glue frame, and the high-strength PU glue frame is tightly connected with the high-dust-holding filter element and the metal bottom net.

[0009] The beneficial effects of an air filter with a high-dust-holding flow channel provided by the present utility model are as follows: The air filter with a high-dust-holding flow channel has a simple structure and a reasonable design. Through the structural design of the air flow channel in the filter element, the dust-holding capacity and filtering effect of the filter element can be enhanced, thereby improving the service life of the air filter. During actual processing, a runway-shaped bubbling origami roller die arranged regularly is used to press raised indentations on a flat filter paper. After the filter paper is formed, the raised inner bubbles and outer bubbles are connected in reverse every time to support the gaps between each layer of filter paper, so that a smooth air flow channel is formed between each column of bubbles and each row of bubbles. When the air filter is working, air smoothly enters from the air inlet surface and passes through the filter paper, outer bubbles, filter paper, outer bubbles, filter paper in sequence, or passes through the filter paper, inner bubbles, filter paper, inner bubbles, filter paper in sequence, so that dust or impurities in the air cover the surface of the filter paper as much as possible (that is, the effective filtration utilization rate of the filter paper is as high as possible), thereby effectively improving the dust-holding capacity of the filter paper and ensuring a higher service life of the air filter. In addition, the staggered distributed raised inner bubbles and outer bubbles pressed on the filter paper also play a role in strengthening the stiffness of the filter paper, so that the filter element has a stronger wind resistance effect.

[0018] Refer to Figures 1 to 5 As shown, an air filter with a high-dust-holding flow channel includes: a bottom frame 1, a bottom net 2, and a high-dust-holding filter element 3. The bottom net 2 is fixed on the bottom frame 1, and the high-dust-holding filter element 3 is installed on the bottom net 2. The bottom net 2 is a metal net, and 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 high-dust-holding filter element 3 can be strengthened, and the shielding of the bottom net 2 from the high-dust-holding filter element 3 can be reduced, improving the impact resistance and air passing capacity of the high-dust-holding filter element 3. The bottom frame 1 is a PU glue frame, and the high-strength PU glue frame is tightly connected to the high-dust-holding filter element 3 and the metal bottom net 2. The high-dust-holding filter element 3 is folded from filter paper 7. Two parallel and spaced fixed hot melt adhesives 4 are pasted on the bottom surface of the high-dust-holding filter element 3, and two parallel and spaced sealing hot melt adhesives 4 are pasted on the top surface of the high-dust-holding filter element 3. By setting the hot melt adhesive 4 on the surface, on the one hand, the shaping ability of the top and bottom surfaces of the high-dust-holding filter element can be enhanced, and on the other hand, it is also convenient for the docking and sealing installation with external equipment. Two rows of outer bulges 5 or inner bulges 6 are arranged side by side and spaced apart along the Z direction on the high-dust-holding filter element 3, and the outer bulges 5 and the inner bulges 6 are arranged side by side and spaced apart and staggered along the X direction. Through the structural design of the outer bulges 5 and the inner bulges 6, the stiffness of the high-dust-holding filter element 3 can be strengthened, and the dust-holding capacity and filtration effect of the high-dust-holding filter element 3 can be enhanced.

[0019] The air filter with a high dust-holding channel has a simple structure and a reasonable design. By designing the structure of the air channel in the high dust-holding filter element 3, the dust-holding capacity and filtration effect of the high dust-holding filter element 3 can be enhanced, thereby improving the service life of the air filter. During actual processing, a runway-shaped bubbling origami roller die arranged regularly is used to press raised indentations on the flat filter paper. After the filter paper is formed, the raised inner bubbles 5 and outer bubbles 6 are connected in reverse every time to support the gaps between each layer of filter paper, so that a smooth air channel is formed between each column and each row of bubbles. When the air filter is working, air smoothly enters from the intake surface and passes through the filter paper 7, outer bubble 6, filter paper 7, outer bubble 6, filter paper 7 in sequence, or passes through the filter paper 7, inner bubble 5, filter paper 7, inner bubble 5, filter paper 7 in sequence, so that as much dust or impurities in the air as possible cover the surface of the filter paper 7 (that is, the effective filtration utilization rate of the filter paper 7 is as high as possible), thereby effectively improving the dust-holding capacity of the filter paper 7 and ensuring a higher service life of the air filter. In addition, the staggered distribution of the raised inner bubbles 5 and outer bubbles 6 pressed on the filter paper 7 also plays a role in strengthening the stiffness of the filter paper 7, enabling the high dust-holding filter element 3 to have a stronger wind pressure resistance effect.
