Description

Technical Field

[0002] An air filtration device is a device used to purify air and remove impurities and pollutants from it. It is widely used in industrial, commercial and household fields.

[0003] Normally, air needs to flow through the filter element of an air filtration device to achieve filtration. For example, air is rapidly passed through the filter element when a vehicle is in motion, or air is forced through the filter element by creating negative pressure. At this time, the air has a certain kinetic energy, and during the air flow, it is easy to cause structural vibration and collision, thereby generating a large amount of noise.

Detailed Implementation

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0058] According to a first aspect of this application, this application provides an air filtration device 100, please refer to... Figures 1-9 As shown.

[0059] An air filtration device 100 according to an embodiment of this application includes a housing 101, a filter element 102, and a sound-absorbing structure 111. The housing 101 forms an inner cavity 141. The filter element 102 is used to filter air and is disposed in the inner cavity 141. The sound-absorbing structure 111 is part of the housing 101.

[0060] It is understood that the filter element 102 is used for air filtration. Specifically, dirty external air can enter the inner cavity 141 of the housing 101 and be filtered by the filter element 102. Air can be introduced into the inner cavity 141 of the housing 101 through a pipe and then filtered by the filter element 102. Alternatively, an air inlet 121 can be provided on the housing 101 to allow air to enter. The silencing structure 111 is used to process air and sound. For example, when air flows through it, the silencing structure 111 can counteract the kinetic energy of the air, thereby reducing structural vibrations and collisions caused by the air's impact on other structures, thus achieving noise reduction. The silencing structure 111 can also process existing noise, such as absorbing sound or canceling it through sound wave reflection, or a combination of both can achieve a better noise reduction effect.

[0061] In the case where the noise reduction structure 111 achieves noise reduction by reducing air kinetic energy, the noise reduction structure 111 can treat dirty air before filtration. For example, if the noise reduction structure 111 is located at the housing 101, the air first passes through the noise reduction structure 111 and then enters the inner cavity 141 and is filtered by the filter element 102. Alternatively, the noise reduction structure 111 can be located in the inner cavity 141, and the air enters the inner cavity 141, is treated by the noise reduction structure 111, and then is filtered by the filter element 102. The silencer structure 111 can also process the filtered clean air. Similarly, the silencer structure 111 can be located in the housing 101. The air that enters the inner cavity 141 and is filtered by the filter element 102 is first exported from the inner cavity 141, and then processed by the silencer structure 111 before being exported from the air filter device 100. The silencer structure 111 can also be located in the inner cavity 141. After the air enters the inner cavity 141, it is filtered by the filter element 102, then processed by the silencer structure 111 in the inner cavity 141, and then exported from the inner cavity 141 to the outside of the air filter device 100.

[0062] Therefore, the air filtration device 100 in this embodiment has a filter element 102 and a noise reduction structure 111, which can achieve both air filtration and noise reduction. In addition, the noise reduction structure 111 is part of the housing 101, which helps to reduce the space occupied by the overall structure. When there are requirements on the size of the air filtration device 100, it is easy to increase the size of the filter element 102 to ensure or even improve the air filtration effect.

[0063] In some embodiments of this application, the air filter device 100 is applied in a vehicle and supplies air intake to the vehicle engine. The air is treated by the filter element 102 and the noise reduction structure 111 to provide clean air to the engine and reduce air-induced noise. At the same time, the noise reduction structure 111 is integrated into the housing 101 as part of the air filter device 100, so that the air filter device 100 can maintain a relatively small volume while ensuring the size of the filter element 102. This reduces the space occupied in the engine compartment, thereby freeing up more engine compartment space and improving the freedom of arrangement of front compartment system components.

[0064] In some embodiments of this application, the air filter 100 is used for a front-end module of a vehicle, and the housing 101 is adapted to serve as a beam of the front-end module.

[0065] The front-end module of the vehicle in this application is the basic frame component of the vehicle, usually located in front of the vehicle's engine. It is used to realize various functions of the vehicle and to ensure vehicle safety and aesthetics. For example, it is a frame component for installing components such as the car's cooling module, headlights, and water tank, as well as frame components such as bumpers and anti-collision beams. In one embodiment of this application, the front-end module is a rectangular frame component with two parallel crossbeam structures and columns 200 on both sides of the crossbeam structures. The housing 101 of the air filter device 100 in this embodiment of the application constitutes the upper crossbeam of the front-end module, and the other crossbeam structure is the bottom crossbeam 300.

[0066] Reference Figure 1 and Figure 2 As shown, in this embodiment, the air filter 100 can be used in a vehicle, specifically in the front-end module of the vehicle. In an optional embodiment, the housing 101 of the air filter 100 is adapted to serve as a beam of the front-end module, and specifically as a crossbeam of the front-end module, to filter the air before it enters the vehicle's engine. The clean air processed by the silencing structure 111 and the filter element 102 can be introduced into the vehicle's engine through the engine intake pipe 400 to achieve engine intake. Thus, when applied in a vehicle, it can reduce NVH (Noise, Vibration, Harshness) risks. When used as a beam structure and integrated into the front-end module of the vehicle, it eliminates the need to place the air filter 100 in the engine compartment, thereby simplifying the use of braided tubing and independent broadband mufflers for noise reduction in the vehicle's engine compartment, improving integration, freeing up more engine compartment space, and increasing the freedom of arrangement of front compartment system components. Similarly, since the silencing structure 111 is part of the housing 101, the size of the filter element 102 can be increased to ensure the filtering effect on the engine intake air when the size of the vehicle's crossbeam structure and the front module of the vehicle is limited, thereby achieving a balance between air filtration effect and noise control.

[0067] In some embodiments of this application, the housing 101 includes a main body portion 151, the main body portion 151 having a receiving groove 151a, and the end face 1114 of the sound-absorbing structure 111 serving as a cover plate for the housing 101 and forming the inner cavity 141 with the receiving groove 151a.

[0068] Reference Figure 2 and Figure 3As shown, in this embodiment, the main body 151 and the sound-absorbing structure 111 are separable and are part of the housing 101. The two form an inner cavity 141 through the receiving groove 151a formed by the main body 151, which also provides for the placement and installation of the filter element 102. This improves the internal integration of the air filtration device 100 and makes it easier to maximize the size of the filter element 102 in a limited space to improve the filtration effect.

[0069] In some embodiments of this application, the filter element 102 divides the inner cavity 141 into a first inner cavity 141a and a second inner cavity 141b, and the filter element 102 is used to filter the air flowing from the first inner cavity 141a to the second inner cavity 141b.

[0070] Reference Figures 4-6 As shown, in this embodiment, the filter element 102 includes a flat plate filter element, so that the opposing surfaces of the filter element 102 can be regarded as the clean side and the dirty side after filtering the air. The filter element 102 divides the inner cavity 141 into a first inner cavity 141a and a second inner cavity 141b. During air filtration, air enters the first inner cavity 141a, passes through the surface of the filter element 102 facing the dirty side, and flows out from the surface of the filter element 102 facing the clean side. After being processed by the sound-absorbing structure 111, it flows out, thereby completely separating the clean side and the dirty side. When using and disassembling and maintaining the air filter structure, it is avoided that impurities on the dirty side contaminate the clean side.

[0071] In some embodiments of this application, the silencing structure 111 is located above the filter element 102 and forms the second inner cavity 141b with the air outlet surface of the filter element 102.

[0072] Reference Figure 2 and Figure 3 As shown, in this embodiment, the silencing structure 111 and the air outlet surface of the filter element 102 form a second inner cavity 141b. At this time, the silencing structure 111 is located above the filter element 102. When disassembling and maintaining the filter element 102, the upper silencing structure 111 can be disassembled first, and then the filter element 102 can be disassembled. This avoids the dust and other impurities of the filter element 102 falling onto the silencing structure 111 when the filter element 102 is moved, which would affect the subsequent noise reduction effect and air filtration effect.

[0073] In some embodiments of this application, the silencing structure 111 is detachably connected to the main body 151, for example, by means of clips, bolts, etc., so as to facilitate the disassembly and assembly of the silencing structure 111 and thus facilitate the maintenance of the filter element 102.

[0074] In some embodiments of this application, the housing 101 is provided with an air inlet 121, and the filter element 102 is used to filter the air entering the inner cavity 141 through the air inlet 121.

[0075] Reference Figures 1-6 As shown, in this embodiment, the housing 101 is provided with an air inlet 121, which is connected to the inner cavity 141. Specifically, the air inlet 121 is connected to the first inner cavity 141a, so that after the air enters the first inner cavity 141a through the air inlet 121, it is filtered by the filter element 102 and flows into the second inner cavity 141b.

[0076] In other embodiments, air can also be introduced by setting a tube and inserting it into the housing 101 with one end located in the inner cavity 141.

[0077] In some embodiments of this application, the silencing structure 111 is provided with an air outlet 131, which is used to allow the air filtered by the filter element 102 to flow out.

[0078] Reference Figures 1-6 As shown, in this embodiment, an air outlet 131 is provided at the housing 101. The air outlet 131 communicates with the inner cavity 141, and specifically, the air outlet 131 communicates with the second inner cavity 141b. Thus, air enters the first inner cavity 141a through the air inlet 121, is filtered by the filter element 102, flows into the second inner cavity 141b, and then flows out through the air outlet 131 after being processed by the sound-absorbing structure 111. When applied to a vehicle, the air outlet 131 can be connected to the vehicle's engine intake pipe 400.

[0079] The sound-absorbing structure 111 can form a pipe interface, and the pipe interface has the air outlet 131, so as to facilitate connection with external pipelines, such as the engine intake pipe 400.

[0080] In other embodiments, the air in the second inner cavity 141b can also be directly discharged from the pipe body, such as the engine intake pipe 400 being directly inserted into the muffler structure 111 and communicating with the second inner cavity 141b.

[0081] In some embodiments of this application, the main body 151 is provided with an air inlet 121, a connecting hole 151b, and a front cavity 151c that is spaced apart from the inner cavity 141. The air inlet 121 is located at the main body 151 and communicates with the front cavity 151c. The connecting hole 151b is used to connect the front cavity 151c and the inner cavity 141.

[0082] Reference Figure 3As shown, in this embodiment, a front cavity 151c is formed at the main body 151, separated from the inner cavity 141. For example, the two cavities are separated by a plate, and a connecting hole 151b is provided on it to connect the front cavity 151c and the inner cavity 141. An air inlet 121 is located at the main body 151 and communicates with the front cavity 151c. It can be understood that when air enters through the air inlet 121, it first enters the front cavity 151c and then the inner cavity 141, and is then filtered by the filter element 102. Based on the preliminary filtration of the front cavity 151c, some larger impurities or liquids in the air can be processed first, thereby extending the service life of the filter element 102 and saving user operating costs.

[0083] In some embodiments of this application, the main body 151 includes a first housing 1511 and a second housing 1512, the first housing 1511 and the second housing 1512 forming the front cavity 151c, the air inlet 121 being disposed at the first housing 1511, the receiving groove 151a being formed at the second housing 1512, and the communicating hole 151b being disposed at the side wall of the receiving groove 151a to communicate the front cavity 151c and the inner cavity 141.

[0084] Reference Figure 3 As shown in the embodiment of this application, the main body 151 is surrounded by two separable first housings 1511 and second housings 1512 to form a front cavity 151c, thereby improving the structural integration. An air inlet 121 is located at the first housing 1511, and a connecting hole 151b is located at the side wall of the receiving groove 151a, so as to achieve sequential communication between the inner cavity 141, the front cavity 151c, and the air inlet 121. It can be understood that the receiving groove 151a, i.e., the inner cavity 141, is fixedly installed with a filter element 102 for air filtration, while the front cavity 151c performs preliminary filtration. When maintenance and cleaning of the front cavity 151c are required, the second housing 1512 can be removed first. At this time, the filter element 102 installed in this part is also removed simultaneously. Subsequently, when cleaning impurities in the front cavity 151c, the filter element 102 will not be contaminated.

[0085] In one specific embodiment, the second housing 1512 is located above the first housing 1511, and the two together form a front cavity 151c. During subsequent air filtration, most of the contaminants are contained in the front cavity 151c, specifically on the upper surface of the first housing 1511.

[0086] The first housing 1511 and the second housing 1512 are detachably connected, for example, by means of clips, bolts or other detachable connections, so as to facilitate the assembly and disassembly of the first housing 1511 and the second housing 1512, and thus also facilitate the maintenance of the filter element 102 and the pre-cavity 151c.

[0087] Reference Figure 3 As shown, in some embodiments of this application, the first housing 1511 is provided with a sound-absorbing tile 103 near the bottom surface of the receiving groove 151a, so as to perform targeted noise reduction when the filter element 102 in the receiving groove 151a filters the air, and further improve the noise reduction effect of the overall structure.

[0088] In some embodiments of this application, the front cavity 151c is provided with an air guiding structure 104, which is used to guide the air entering through the air inlet 121 into the inner cavity 141.

[0089] In this embodiment, by providing an air guiding structure 104 in the front cavity 151c of the air filtration device 100, the air from the air inlet 121 is guided to the inner cavity 141 so that it can be filtered by the filter element 102 in the inner cavity 141. This reduces the noise generated and ensures better airflow and filtration effect.

[0090] The air guiding structure 104 can be a guide vane, a wind deflector 104a, etc.

[0091] In some embodiments of this application, the air guiding structure 104 includes an air guide plate 104a.

[0092] Reference Figures 3-5 As shown, air is guided by a guide plate 104a, which has a simple structure and is easy to manufacture. In addition, when the air entering through the air inlet 121 impacts the guide plate 104a, it can be better pre-filtered due to the obstruction of the guide plate 104a, such as blocking impurities or liquids before they reach the inner cavity 141, thereby ensuring a better subsequent filtration effect.

[0093] In some embodiments of this application, the air guide plate 104a divides the front cavity 151c into an air circulation cavity 151c1 and a resonant cavity 151c2, and the air guide plate 104a is provided with a single-pass pipe 114 for unidirectional communication between the air circulation cavity 151c1 and the resonant cavity 151c2.

[0094] Reference Figures 3-5As shown in the embodiment, the air guide plate 104a divides the front cavity 151c into two parts. One part forms an air circulation cavity 151c1 for smooth airflow and guidance to the inner cavity 141, and the other part forms a resonant cavity 151c2. A one-way pipe 114 is set at the air guide plate 104a to form a one-way communication between the air circulation cavity 151c1 and the resonant cavity 151c2. During the airflow process, the air molecules entering the resonant cavity 151c2 reciprocate within the resonant cavity 151c2, thereby generating a certain vibration frequency in the resonant cavity 151c2. When the frequency of the sound wave outside the resonant cavity 151c2 is the same as the vibration frequency of the resonant cavity 151c2, resonance occurs, thereby absorbing the sound wave and achieving noise reduction. Based on this structural form, low-frequency noise during airflow can be reduced to a certain extent, thereby improving the overall noise reduction effect.

[0095] In some embodiments of this application, the air guide surface of the air guide plate 104a is curved.

[0096] In this embodiment, the surface of the air guide plate 104a is curved to improve the air conduction effect.

[0097] In some embodiments of this application, there are multiple air guide plates 104a.

[0098] In this embodiment, there are multiple air guide plates 104a, which guide the air and improve the air conduction effect, ensuring that the air flows accurately into the inner cavity 141.

[0099] In some embodiments of this application, at least two of the air guide plates 104a are spaced apart within the front cavity 151c to form an air guide channel 124.

[0100] Reference Figure 5 As shown, in this embodiment, two curved air guide plates 104a are spaced apart, forming an air guide channel 124 between them. Thus, when air enters the air filter device 100 through the air inlet 121, it is guided by the air guide channel 124 to improve the air conduction effect.

[0101] In some embodiments of this application, the main body portion 151 is provided with a sound-absorbing tile 103 near the surface of the front cavity 151c.

[0102] Reference Figure 3 As shown, specifically, a sound-absorbing tile 103 is provided on the top surface of the main body 151 above the front cavity 151c, so that when air enters the front cavity 151c, targeted noise reduction is performed, further improving the overall noise reduction effect of the structure.

[0103] In some embodiments of this application, the main body portion 151 has a drainage hole 105 on its bottom surface located below the front cavity 151c.

[0104] Reference Figure 4 and Figure 5 As shown, a drain hole 105 is provided on the bottom surface of the main body 151 below the pre-cavity 151c, that is, a drain hole 105 is provided between the inner cavity 141 where the filter element 102 is located and the air inlet 121, so as to discharge the liquid during the initial filtration of air, and slow down the process of the liquid causing the filter element 102 to become damp and contaminated. Furthermore, a guide plate 104a is provided. Based on the obstruction of the guide plate 104a, the liquid drips to the bottom of the housing 101. The drain hole 105 is specifically provided here to improve the drainage efficiency.

[0105] In some embodiments of this application, the bottom surface of the housing 101 located below the inner cavity 141 is provided with a drain hole 105.

[0106] Reference Figure 4 and Figure 5 As shown, a drain hole 105 is provided on the bottom surface of the housing 101 below the inner cavity 141 to drain the liquid at the filter element 102, slow down the process of the liquid causing the filter element 102 to become damp, and improve the service life of the filter element 102 and the air filtration device 100 as a whole.

[0107] In an optional embodiment, a sound-absorbing tile 103 is provided on the housing 101 below the inner cavity 141, and a drainage hole 105 is provided at the sound-absorbing tile 103 for drainage.

[0108] In some embodiments of this application, the silencing structure 111 includes a perforated plate 1111 and a silencing cavity 1112, wherein the through holes of the perforated plate 1111 are connected to the silencing cavity 1112.

[0109] Reference Figure 2 as well as Figures 7-9 As shown, in this embodiment, the silencing structure 111 has a silencing cavity 1112 and a perforated plate 1111 so that the inside and outside of the silencing cavity 1112 can be connected through the through holes of the perforated plate 1111. The filtered clean air can flow to the silencing structure 111, pass through the through holes of the perforated plate 1111 and repeatedly enter and exit the silencing cavity 1112 to reduce kinetic energy and achieve the effect of silencing, thereby reducing the noise generated by the subsequent air flow interfering with other structures.

[0110] In some embodiments of this application, the silencing structure 111 further includes a plurality of partitions 1113, which are spaced apart within the silencing cavity 1112 to divide the silencing cavity 1112 into a plurality of sub-silencing cavities 1112a.

[0111] Reference Figures 7-9 As shown, in this embodiment, multiple partitions 1113 divide the anechoic chamber 1112 into multiple sub-anechoic chambers 1112a, that is, a sub-anechoic chamber 1112a is formed between two adjacent partitions 1113, thereby restricting the airflow to a certain extent, further reducing the kinetic energy of the airflow, and weakening the generation of noise. The partitions 1113 can be set at an angle to the direction of airflow to further reduce the kinetic energy of the airflow and weaken the noise generated subsequently.

[0112] In some embodiments of this application, the perforated plate 1111 is disposed opposite to the air outlet surface of the filter element 102.

[0113] In this embodiment, the perforated plate 1111 and the air outlet surface of the filter element 102 are arranged opposite to each other so that the clean air filtered by the filter element 102 can directly enter the above-mentioned silencing cavity 1112 through the through holes of the perforated plate 1111 to reduce kinetic energy and achieve noise reduction, thereby ensuring the noise reduction effect.

[0114] In some embodiments of this application, the silencing structure 111 further includes an upper end face 1114, one end of the perforated plate 1111 is connected to the upper end face 1114, the other end of the perforated plate 1111 extends away from the upper end face 1114, and the silencing cavity 1112 is formed between the perforated plate 1111 and the upper end face 1114.

[0115] In this embodiment, the silencing cavity 1112 in the silencing structure 111 is formed by the upper end face 1114 of the silencing structure 111 and the perforated plate 1111. The upper end face 1114 of the silencing structure 111 is also part of the top surface of the shell 101. One end of the perforated plate 1111 is connected to the upper end face 1114, and the other end extends away from the upper end face 1114. That is, the perforated plate 1111 is inclined relative to the upper end face 1114, thereby forming the silencing cavity 1112 between the two. The other end away from the upper end face 1114 can be connected to the upper end face 1114 through the partition 1113, thereby forming a silencing cavity 1112 structure with gradually increasing cross-sectional size. Its interior can also be divided into multiple sub-silencing cavities 1112a by the partition 1113. The volume of these sub-silencing cavities 1112a changes sequentially, so that when air enters the silencing cavity 1112 through the perforated plate 1111, a better noise reduction effect can be achieved.

[0116] In some embodiments of this application, the filter element 102 includes a filter element body 112 and a binding strip 122 surrounding the filter element body 112, the binding strip 122 being used to fit against the surface of the housing 101.

[0117] Reference Figure 2As shown, in this embodiment, the filter element 102 includes a filter element body 112 to achieve air filtration. A binding strip 122 is provided around the outer periphery of the filter element body 112 to achieve the installation and fixation of the filter element body 112. During installation and fixation, the filter element 102 is airtight by adhering to the surface of the housing 101, thereby separating the two sides of the filter element 102 to avoid contamination of the clean side by the dirty side.

[0118] Among them, the edge banding strip 122 can be a PU (Polyurethane) strip.

[0119] In some embodiments of this application, a connecting edge 106 is provided at the housing 101, and the sound-absorbing structure 111 is used to cooperate with the connecting edge 106 to press the edge strip 122.

[0120] Reference Figure 2 As shown, in this embodiment, a connecting edge 106 is provided at the housing 101. Specifically, the connecting edge 106 can be provided around the outer periphery of the receiving groove 151a at the second housing 1512. So when the filter element 102 is installed in the inner cavity 141 formed by the receiving groove 151a, the edge strip 122 fits with the connecting edge 106. When the sound-absorbing structure 111 is installed, the edge of the sound-absorbing structure 111 cooperates with the connecting edge 106 to press the edge strip 122, thereby ensuring airtightness.

[0121] In some embodiments of this application, the filter element 102 is disposed at an angle in the inner cavity 141.

[0122] Reference Figure 2 As shown, by arranging the filter element 102 at an angle, the external surface area of ​​the filter element 102 can be increased within the housing 101 of the same size, thereby ensuring a higher degree of structural integration while improving the air filtration effect.

[0123] In some embodiments of this application, the housing 101 is provided with sound-absorbing tiles 103 to further improve the sound absorption and noise reduction effect of the overall structure.

[0124] In some embodiments of this application, the sound-absorbing tile 103 has a porous structure.

[0125] In this embodiment, the sound-absorbing tile 103 is made of PET (Polyethylene Terephthalate) plastic, which has a dense porous structure, thereby improving the noise reduction effect.

[0127] The crossbeam of this embodiment has the same or similar technical effects as the air filter device 100 described above, and will not be described again here.

[0128] In addition, the air filter device 100 in this application serves as a crossbeam of the vehicle, specifically, the crossbeam is applied to the front-end module of the vehicle.

[0129] The housing 101 of the air filter device 100, serving as the beam of the crossbeam, integrates the aforementioned structures for air filtration and noise reduction while meeting structural strength requirements. This improves vehicle integration; when applied to engine intake air filtration in vehicles, it simplifies the use of braided tubing and independent wideband mufflers while maintaining filtration and noise reduction effects; and it frees up more engine compartment space, increasing the flexibility of front compartment system component placement.

The air filter device 100, which serves as the vehicle crossbeam in this application, constitutes the top crossbeam of the vehicle's front-end module. This improves vehicle integration; when applied to engine intake air filtration in vehicles, it simplifies the use of braided tubing and independent wideband mufflers while maintaining noise reduction, and frees up more engine compartment space, increasing the flexibility of front compartment system component placement.
