Description

Technical Field

[0001] The present invention relates to the technical field of high-position intake pipes, and particularly to a high-position intake pipe capable of absorbing dust. Background Art

[0002] The main function of the high-position intake pipe is to introduce the air from the air filter into the engine to provide the oxygen required for combustion. At the same time, the design of the high-position intake pipe can also reduce the gas flow resistance and improve the intake capacity. In addition, for some off-road vehicles or vehicles that often drive on rough roads, the high-position intake pipe (wading snorkel) can also raise the position of the intake port to prevent water from invading the engine, thereby protecting the core components of the vehicle from damage.

[0003] After retrieval, a Chinese patent with the publication number CN213510970U discloses a high-position intake pipe assembly for heavy trucks, including an intake cap body. A connecting pipe is arranged on the lower surface of the outer wall of the intake cap body. The lower end of the connecting pipe is provided with a main transportation pipe, and the lower end of the main transportation pipe is fixed on the outer wall of the intake box. The upper surface and the lower surface of the inner wall of the intake box are respectively provided with dust absorption components. Each dust absorption component includes a fixing module. On one side of each fixing module, a support frame is symmetrically arranged. At one end of each support frame away from the fixing module, an intermediate rotating shaft is arranged. An adapter ring body is arranged on each intermediate rotating shaft. Four connecting rods are equidistantly arranged around each adapter ring body. At one end of each connecting rod away from the connecting ring body, a rectangular graphene plate is arranged. Through the dust absorption components, the absorption of dust inside the high-position intake pipe assembly for heavy trucks is realized, thereby protecting the engine compartment, avoiding uneven heat dissipation caused by dust accumulation, preventing engine damage, and prolonging the service life of the engine. However, when this solution is actually used, there are still the following deficiencies: As an important part of the vehicle engine intake system, the high-position intake pipe is usually arranged outside the vehicle engine to introduce fresh air from a relatively clean and well-ventilated position. However, in actual applications, the production of high-position intake pipes often follows standardized length specifications. Once produced, their lengths are fixed, lacking flexibility. This fixed-length design shows low adaptability when facing different vehicle models, different engine layouts, and changing driving environments. At the same time, as the vehicle usage changes, such as in special scenarios like off-road driving and wading through water, new requirements may be put forward for the length and position of the high-position intake pipe. However, due to the non-adjustable length of the high-position intake pipe, in some cases, the length of the intake pipe may be too long or too short, which not only affects the intake efficiency but also may have an adverse impact on the driving performance and safety of the vehicle.

[0022] Refer to Figures 1-9 , a high-position intake pipe capable of sucking dust, including an intake pipe body 1 and a branch pipe 2. The branch pipe 2 is arranged at the top end of the intake pipe body 1. A connecting pipe 3 is fixedly installed at the bottom end of the intake pipe body 1. One end of the branch pipe 2 away from the intake pipe body 1 is fixedly installed with an intake hood 4. A plurality of flow guiding strips 5 arranged in a linear array are fixedly installed on the inner wall of the open end of the intake hood 4. An ash removing assembly is arranged inside the intake hood 4 for sucking the dust in the gas entering the intake hood 4. A connecting assembly is arranged at the connection between the intake pipe body 1 and the branch pipe 2 for adjusting the use height of the intake hood 4. A sealing ring sleeve 9 is fixedly sleeved on the outer wall of the connecting pipe 3. An annular cavity 10 is opened at the end of the sealing ring sleeve 9. A sealing assembly is arranged in the annular cavity 10 for sealing the connection between the connecting pipe 3 and the vehicle pipe body; During use, the connecting pipe 3 at the bottom end of the intake pipe body 1 can be connected to the pipe body of the vehicle. When connecting, the connecting pipe 3 can be inserted into the pipe body of the vehicle. The pipe body of the vehicle can be located between the sealing ring sleeve 9 and the connecting pipe 3. During the installation process, the sealing assembly in the annular cavity 10 can seal the gap between the vehicle pipe body and the connecting pipe 3 to avoid air leakage. Then, the overall length of the intake pipe can be adjusted through the connecting assembly according to the use scenario and the specific situation of the vehicle, so that the intake of the intake hood 4 is smoother. During use, the ash removing assembly in the intake hood 4 can remove dust from the gas entering the intake hood 4 and suck the dust to avoid the influence of dust on the engine.

[0023] The ash removal component includes a deflector plate 61 symmetrically and fixedly installed on the inner wall of the opening end of the air inlet hood 4, a fixing plate 62 symmetrically and fixedly installed on the inner wall of the air inlet hood 4, and a filter net 63 penetrating through the sides of the two fixing plates 62. The deflector plate 61 is set to be arc-shaped. Two ash collection shells 64 corresponding to the fixing plates 62 penetrate through the bottom surface of the air inlet hood 4. A knocking mechanism adapted to the filter net 63 is symmetrically arranged inside the air inlet hood 4; The knocking mechanism includes a shaft rod 65 rotatably installed between the fixing plate 62 and the inner wall of the air inlet hood 4, several blades 66 fixedly installed on the outer wall of one end of the shaft rod 65 in an annular array distribution, and a driving half gear 67 fixedly sleeved on the end of the shaft rod 65. A rotating shaft 68 is rotatably installed between the fixing plate 62 and the inner wall of the air inlet hood 4. A transmission gear 69 is fixedly sleeved on the end of the rotating shaft 68. The transmission gear 69 meshes with the driving half gear 67. A torsion spring 610 is sleeved on the end of the rotating shaft 68 away from the transmission gear 69. Several knocking plates 611 are fixedly installed on the outer wall of the rotating shaft 68 in a linear array distribution. A knocking head 7 is fixedly installed at the bottom end of the knocking plate 611. The knocking head 7 is made of rubber material; During the use of the intake pipe, gas can enter the air inlet hood 4. Under the action of the deflector plate 61, the gas can flow towards the fixing plates 62 at both ends of the air inlet hood 4. And under the action of density, since the density of dust is greater than that of air, the mass of dust is greater, that is, the inertia is greater. Therefore, when flowing at high speed, the dust can flow along the arc surface of the deflector plate 61 to the fixing plate 62 and is filtered by the filter net 63. The gas can enter the branch pipe 2 through the space between the two fixing plates 62 and the filter net 63 to achieve air intake. At the same time, during the air intake process, the blades 66 can be blown by the flowing gas to drive the shaft rod 65 to rotate. During the rotation of the shaft rod 65, the driving half gear 67 can be driven to rotate. When the driving half gear 67 rotates and meshes with the transmission gear 69, the transmission gear 69 and the rotating shaft 68 can be driven to rotate. When the driving half gear 67 is separated from the transmission gear 69, under the action of the torsion spring 610, the rotating shaft 68 can rotate in the reverse direction, so as to realize the reciprocating rotation of the rotating shaft 68. Thus, the filter net 63 can be knocked by the knocking plates 611 and the knocking heads 7 on the rotating shaft 68, so that the filter net 63 vibrates, so that the filtered dust can enter the ash collection shell 64, and the user can clean the ash collection shell 64 regularly.

[0024] The connecting component includes an annular groove 81 opened at the bottom end of the branch pipe 2, a sealed stretching sleeve 82 sleeved between the branch pipe 2 and the air inlet pipe body 1, and an adjusting ring 83 slidably mounted on the outer wall of the air inlet pipe body 1. A fixing ring 84 is fixedly sleeved on the outer wall of the branch pipe 2. The sealed stretching sleeve 82 is located between the adjusting ring 83 and the fixing ring 84. A plurality of ejector rods 85 distributed in an annular array are fixedly installed between the fixing ring 84 and the adjusting ring 83. An installation plate 86 is rotatably mounted on the outer wall of the adjusting ring 83, and an installation opening is formed on the installation plate 86; When adjusting the length of the air inlet pipe, first, the installation plate 86 can be pulled to drive the adjusting ring 83 to slide along the outer wall of the air inlet pipe body 1. During the sliding process of the adjusting ring 83, the fixing ring 84 and the branch pipe 2 can be driven through the ejector rods 85, so that the branch pipe 2 slides along the top end of the air inlet pipe body 1 through the annular groove 81, realizing the adjustment of the overall length of the air inlet pipe. After the adjustment is completed, the installation plate 86 can be fixed on the A-pillar of the vehicle body by screws. Through the fixing of the cable ties, the installation plate 86 and the screws, it is ensured that the branch pipe 2 can be used stably. At the same time, the sealed stretching sleeve 82 can be sleeved at the connection between the branch pipe 2 and the air inlet pipe body 1, ensuring the sealing performance of the connection.

[0025] The sealing component includes a sealed capsule ring 111 arranged inside the annular cavity 10, a plurality of connecting rods 112 distributed in an annular array and penetrating through the inner wall of the sealing ring sleeve 9, and a pressing plate 113 fixedly installed at one end of the connecting rod 112 located inside the annular cavity 10. The inside of the sealed capsule ring 111 is filled with sealing glue. A transmission plate 114 is fixedly installed at the end of the connecting rod 112 away from the pressing plate 113. The side of the transmission plate 114 away from the connecting rod 112 is provided with an inclined surface. A relief groove 115 corresponding to the transmission plate 114 is formed on the inner wall of the sealing ring sleeve 9. A plurality of glue outlet nozzles 116 distributed in an annular array and communicating with the annular cavity 10 are formed on the inner wall of the sealing ring sleeve 9. A sealed thread ring 117 is screwed at the opening end of the annular cavity 10, and a dial block 12 is symmetrically fixedly installed on the side surface of the sealed thread ring 117; When installing the intake pipe body 1, first, the sealing threaded ring 117 can be removed from the annular cavity 10 through the shift block 12, and the sealing capsule ring 111 filled with sealant can be installed in the annular cavity 10, and then the sealing threaded ring 117 can be reset, and then the vehicle pipe body can be inserted into the connecting pipe 3. During the insertion process, the vehicle pipe body can squeeze the transmission plate 114 so that the transmission plate 114 drives the connecting rod 112 and the extrusion plate 113 to move. During the movement of the extrusion plate 113, the sealing capsule ring 111 can be squeezed so that the sealing capsule ring 111 can be broken under the action of pressure, and the internal sealant can be discharged through the glue outlet nozzle 116 under the action of pressure into the gap between the sealing ring sleeve 9 and the vehicle pipe body, so as to seal the gap and avoid air leakage. After the installation is completed, the transmission plate 114 can enter the give way groove 115 to avoid the transmission plate 114 affecting the installation and insertion of the vehicle pipe body, and then the outer wall of the connection position between the vehicle pipe body and the connecting pipe 3 is fixed with a cable tie to complete the fixation of the connecting end.

[0026] The specific working principle of the present invention is as follows: When in use, the connecting pipe 3 at the bottom end of the intake pipe body 1 can be connected to the pipe body of the vehicle. When connecting, the connecting pipe 3 can be inserted into the pipe body of the vehicle. The pipe body of the vehicle can be located between the sealing ring sleeve 9 and the connecting pipe 3. During the installation process, the sealing component in the annular cavity 10 can seal the gap between the vehicle pipe body and the connecting pipe 3 to avoid air leakage. Then, the overall length of the intake pipe can be adjusted through the connecting component according to the usage scenario and the specific situation of the vehicle, so that the air intake of the intake hood 4 is smoother. During use, the dust removal component in the intake hood 4 can remove dust from the gas entering the intake hood 4 and absorb dust to avoid dust affecting the engine. Specifically, when installing the intake pipe body 1, first, the sealing threaded ring 117 can be removed from the annular cavity 10 through the shifting block 12, and the sealing capsule ring 111 filled with sealant can be installed in the annular cavity 10, and then the sealing threaded ring 117 can be reset, and then the vehicle pipe body can be inserted into the connecting pipe 3. During the insertion process, the vehicle pipe body can squeeze the transmission plate 114 so that the transmission plate 114 drives the connecting rod 112 and the extrusion plate 113 to move. During the movement of the extrusion plate 113, the sealing capsule ring 111 can be squeezed so that the sealing capsule ring 111 can be broken under the action of pressure, and the internal sealant can be discharged through the glue outlet nozzle 116 under the action of pressure into the gap between the sealing ring sleeve 9 and the vehicle pipe body, so as to achieve sealing of the gap and avoid air leakage. After the installation is completed, the transmission plate 114 can enter the clearance groove 115 to avoid the transmission plate 114 affecting the installation and insertion of the vehicle pipe body, and then the outer wall of the connection position between the vehicle pipe body and the connecting pipe 3 is fixed with a cable tie to complete the fixation of the connecting end; When adjusting the length of the intake pipe, first, the mounting plate 86 can be pulled to drive the adjusting ring 83 to slide along the outer wall of the intake pipe body 1. During the sliding process of the adjusting ring 83, the fixed ring 84 and the branch pipe 2 can be driven by the ejector rod 85 to slide, so that the branch pipe 2 slides along the top end of the intake pipe body 1 through the annular groove 81, realizing the adjustment of the overall length of the intake pipe. After the adjustment is completed, the mounting plate 86 can be fixed on the A-pillar of the vehicle body with screws. Through the fixation of the cable ties, the mounting plate 86 and the screws, the stable use of the branch pipe 2 is ensured. At the same time, the sealing stretch sleeve 82 can be sleeved at the connection between the branch pipe 2 and the intake pipe body 1 to ensure the sealing performance of the connection. During the use of the intake pipe, gas can enter the intake hood 4, and under the action of the flow guide plate 61, the gas can flow towards the fixing plates 62 at both ends of the intake hood 4. And under the action of density, since the density of dust is greater than that of air, the mass of dust is greater, that is, the inertia is greater. Therefore, when flowing at high speed, the dust can flow along the arc surface of the flow guide plate 61 to the fixing plate 62 and realize the filtration of dust under the action of the filter net 63, while the gas can enter the branch pipe 2 through between the two fixing plates 62 and the filter net 63 to realize air intake. At the same time, during the air intake process, the blades 66 can be blown by the flowing gas to drive the shaft rod 65 to rotate. During the rotation of the shaft rod 65, the driving half gear 67 can be driven to rotate. When the driving half gear 67 meshes with the transmission gear 69 during rotation, the transmission gear 69 and the rotating shaft 68 can be driven to rotate. When the driving half gear 67 is separated from the transmission gear 69, the rotating shaft 68 can be reversed under the action of the torsion spring 610 to realize the reciprocating rotation of the rotating shaft 68. Thus, the filter net 63 can be knocked by the knocking plate 611 and the knocking head 7 on the rotating shaft 68 to make the filter net 63 vibrate, so that the filtered dust can enter the dust collecting shell 64, and the user can clean the dust collecting shell 64 regularly.
