Description
Technical Field
[0001] The present invention relates to the technical field of intake systems for vehicles, and specifically to a high-position intake pipe with a dust suction component. Background Art
[0002] The high-position intake pipe, also known as the "wading snorkel", is mainly used for the modification of off-road vehicles. Its function is to prevent water from entering the engine when the vehicle wades through water, thereby avoiding engine damage. The principle of this modification is to cut off the shunt pipeline originally located at the position of the vehicle grille, punch holes at the positions of the fenders on both sides of the vehicle, install a sealed and waterproof intake engineering plastic pipe, connect it to the original vehicle shunt pipeline of the engine and seal it. The design of the high-position intake pipe takes into account the operating principle of the internal combustion engine. During the operation of the internal combustion engine, especially during the compression stroke, the piston moves upward, compressing the air in the cylinder to generate high temperature, which is used to evaporate the liquid fuel into gas. If water is inhaled by the engine at this time, since water can hardly be compressed, the piston cannot reach the top dead center, which may lead to engine stalling or even damage. Therefore, the high position of the intake pipe can effectively prevent water from entering the engine through the air intake when driving on a waterlogged road.
[0003] Although the high-position intake pipe can prevent water from entering the engine, in order to prevent dust in the air from entering the engine when inhaling air, an air filter is usually installed at the shunt pipe and the engine intake end. Its function is to filter the air entering the engine to protect the inside of the engine from dust and other particulate matter.
[0004] In the prior art, with the long-term inhalation of air, the filter element of the air filter adsorbs a large amount of dust, resulting in a large filtration burden on the air filter. At the same time, the filter element of the air filter needs to be cleaned frequently. And the installation position of the air filter is usually inside the vehicle body, and it is troublesome to disassemble and clean, which will affect the normal use of the vehicle. If it is not cleaned frequently, it will affect the engine air intake volume, thereby affecting the engine power output.
[0005] The root cause of the above series of problems is that the dust entering the high-position intake pipe cannot be discharged independently.
[0006] Therefore, the present invention aims to propose a high-position intake pipe that can independently discharge the accumulated dust inside to the outside of the pipe through a dust suction component. The main purpose of the technical solution of the present invention is to discharge a part of the dust from the inside of the pipe to the outside to reduce the pressure of the air filter and assist in dust removal, rather than absolute dust removal. Summary of the Invention
[0007] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a high-position intake pipe with a dust suction component to solve the problem that dust is difficult to discharge into the high-position intake pipe in the above-mentioned background technology, thus causing the filter element of the air filter to be blocked and requiring frequent disassembly and cleaning.
[0008] To achieve the above object, the present invention provides the following technical solution: A high-position intake pipe with a dust suction component, including a main pipe and a rain shield installed on its top, further including an elastic rectifying plate arranged inside the intake end of the main pipe for blocking dust and discharging dust to the edge, a sliding ring located at the bottom of the elastic rectifying plate for collecting edge dust, and a dust suction mechanism for discharging the dust at the edge of the sliding ring out of the main pipe and collecting it again based on the bumpy state of the vehicle;
[0009] The elastic rectifying plate is arranged in a spiral structure inclined along the intake direction, and the outer edge of the sliding ring and the inner wall of the main pipe form a groove with an inclined surface facing the inner wall of the main pipe.
[0010] Preferably, a central column rotatably connected to the rain shield is arranged at the center of the elastic rectifying plate, and the inner edge of the elastic rectifying plate fits the outer wall of the central column, and the outer edge of the elastic rectifying plate is close to the inner wall of the main pipe. Filter holes are evenly arranged inside the elastic rectifying plate.
[0011] Preferably, a fixing rod fixed to one end of the elastic rectifying plate is fixed to the outer surface of the upper end of the central column, and a moving block fixed to the other end of the elastic rectifying plate is arranged on the outer surface of the lower end of the central column. The side wall of the outer wall of the moving block facing the upper surface of the elastic rectifying plate is inclined.
[0012] Preferably, a sliding column is fixed to the end face of the moving block, and a sliding groove slidably matched with the sliding column is arranged on the outer wall of the central column.
[0013] Preferably, the lower end of the sliding ring is slidably arranged on the inner wall of the main pipe, and a T-shaped slider is fixed to the bottom of the moving block inside the sliding ring, and an annular groove slidably matched with the T-shaped slider is arranged on the inner wall of the sliding ring.
[0014] Preferably, a counterweight ring slidably matched with the main pipe is arranged on the outer wall of the main pipe. A traction rope is fixedly connected between the bottom of the sliding ring and the top of the counterweight ring. The traction rope passes through the main pipe, and limiting rings are fixed to both ends of the outer wall of the main pipe where the counterweight ring is located.
[0015] Preferably, the dust suction mechanism includes dust collection cylinders evenly distributed at an equal angle outside the main pipeline. A detachable sealing cover is arranged at the top of the dust collection cylinder. An upper end of the dust collection cylinder is provided with a shunt pipe penetrating through an inner wall of the main pipeline, and a port of the shunt pipe is located above the sliding ring. An air outlet pipe for connecting and communicating the bottom of the dust collection cylinder and the main pipeline is arranged between the bottom of the dust collection cylinder and the main pipeline.
[0016] Preferably, a support ring is fixed to an inner wall of the dust collection cylinder. A filter screen plate slidably matched with the inner wall of the dust collection cylinder is arranged at the top of the support ring. A connecting column is fixedly connected between the filter screen plate and the sealing cover.
[0017] Preferably, a valve plate fitted to the port of the shunt pipe is arranged inside the port of the shunt pipe. A bottom rod penetrating through the bottom of the sliding ring is fixedly connected to the bottom of the valve plate. The bottom rod is in threaded connection with the sliding ring.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] (1) In the present invention, during the driving process of an automobile, air enters from the air inlet end of the main pipeline. If there is less dust on the upper surface of the elastic rectifying plate, most of the air passes through the elastic rectifying plate and is filtered through the filter holes. Since the elastic rectifying plate is inclined along the air inlet direction, a small amount of dust on the upper surface of the elastic rectifying plate will fall outward due to the air flow and the inclined surface and be collected in a groove formed between the outer side of the sliding ring and the inner wall of the main pipeline. Even when the dust moves along the upper surface of the elastic rectifying plate to the end under the drive of the air flow, it can also be guided to the edge of the elastic rectifying plate and slide into the groove outside the sliding ring for collection through the inclined surface on the side wall of the moving block. If there is more dust accumulated on the upper surface of the elastic rectifying plate, after the fluidity of the elastic rectifying plate decreases, under the driving action of the air, a certain centrifugal force will be generated when the elastic rectifying plate rotates, making the dust on its upper surface easier to slide to the outside. Thus, while blocking the dust, it prevents the elastic rectifying plate from being blocked, ensuring the air throughput of the main pipeline and enabling the collection of dust.
[0020] (2) In the present invention, when the vehicle is bumpy during driving, the counterweight ring will slide longitudinally. If the counterweight ring moves upward, the pulling force of the traction rope on the sliding ring is released, and the elastic rectifier plate can pull the sliding ring to slide upward. While sliding, the sliding ring will push the dust in the groove upward. While sliding, the bottom rod will rotate due to the thread on the outer wall of the bottom rod. The bottom rod will drive the valve plate to rotate in the shunt pipe. After the shunt pipe is connected, the airflow will flow with the dust collected in the groove outside the sliding ring. During the flow, the dust is filtered through the filter plate and retained on the upper surface of the filter plate. Even if the sliding ring causes a slight disturbance in the collected dust when sliding, the valve plate has already rotated while the sliding ring moves upward, so the dust can be absorbed. When the weight ring slides down and resets, the sliding ring slides down and resets under the action of the traction rope, and the bottom rod rotates and resets, so that the valve plate rotates and resets to close the diversion pipe. The ash suction mechanism distributed at equal angles can increase its ash collecting capacity. During regular maintenance, you only need to open the sealing cover on the top of the ash collecting cylinder to take out the filter plate through the connecting column to clean the dust on the surface. During the bumpy process, the weight ring slides longitudinally, which can continuously discharge the dust in the groove into the main pipe and collect it. Not only is the maintenance operation convenient, but the dust collected in the air entering the main pipe can be discharged out of the pipe, thereby reducing the burden on the air filter. The main purpose is to discharge part of the dust from the inside of the pipe to the outside of the pipe to reduce the pressure of the air filter element and assist in dust removal, rather than absolute dust removal.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0031] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a high-position intake pipe with an ash suction component, including a main pipeline 1 and a rain shield 2 installed on its top, and further including an elastic rectifying plate 5 arranged inside the intake end of the main pipeline 1 for blocking ash and discharging ash to the edge, a sliding ring 9 located at the bottom of the elastic rectifying plate 5 for collecting edge dust, and an ash suction mechanism for discharging the dust at the edge of the sliding ring 9 out of the main pipeline 1 and collecting it again based on the bumpy state of the vehicle;
[0032] The elastic rectifying plate 5 is arranged in a spiral structure inclined along the intake direction, and a groove is formed between the outer edge of the sliding ring 9 and the inner wall of the main pipeline 1 with an inclined surface facing the inner wall of the main pipeline 1.
[0033] A central column 3 rotatably connected to the rain shield 2 is arranged at the center of the elastic rectifying plate 5, and the inner edge of the elastic rectifying plate 5 is attached to the outer wall of the central column 3. The outer edge of the elastic rectifying plate 5 is close to the inner wall of the main pipeline 1, and filter holes are evenly formed inside the elastic rectifying plate 5.
[0034] A fixing rod 4 fixed to one end of the elastic rectifying plate 5 is fixed to the outer surface of the upper end of the central column 3, and a moving block 6 fixed to the other end of the elastic rectifying plate 5 is arranged on the outer surface of the lower end of the central column 3. The side wall of the moving block 6 facing the upper surface of the elastic rectifying plate 5 is inclined.
[0035] A sliding column 7 is fixed to the end face of the moving block 6, and a sliding groove 8 slidably matched with the sliding column 7 is formed on the outer wall of the central column 3.
[0036] The lower end of the sliding ring 9 is slidably arranged on the inner wall of the main pipeline 1, and a T-shaped slider 10 is fixed to the bottom of the moving block 6 inside the sliding ring 9. An annular groove 101 slidably matched with the T-shaped slider 10 is formed on the inner wall of the sliding ring 9.
[0037] A counterweight ring 11 that is slidably engaged with the outer wall of the main pipe 1 is provided on the outer wall of the main pipe 1. A towing rope 12 is fixedly connected between the bottom of the sliding ring 9 and the top of the counterweight ring 11. The towing rope 12 is arranged to pass through the main pipe 1. Limiting rings 13 are fixedly provided at both ends of the outer wall of the main pipe 1 where the counterweight ring 11 is located.
[0038] The dust suction mechanism includes dust collection cylinders 14 that are equally angularly distributed on the outside of the main pipe 1. A detachable sealing cover is provided at the top of the dust collection cylinder 14. A diversion pipe 15 that penetrates the inner wall of the main pipe 1 is provided at the upper end of the dust collection cylinder 14. And the port of the diversion pipe 15 is located above the sliding ring 9. An air outlet pipe 16 that communicates the two is connected between the bottom of the dust collection cylinder 14 and the main pipe 1.
[0039] A support ring 17 is fixed to the inner wall of the dust collection cylinder 14. A filter screen plate 18 that is slidably engaged with the inner wall of the dust collection cylinder 14 is provided at the top of the support ring 17. A connecting column is fixedly connected between the filter screen plate 18 and the sealing cover.
[0040] A valve plate 19 that fits with it is provided inside the port of the diversion pipe 15. A bottom rod 20 that penetrates to the bottom of the sliding ring 9 is fixedly connected to the bottom of the valve plate 19. The bottom rod 20 is threadedly connected to the sliding ring 9.
[0041] Working principle: When using this high-position intake pipe with a dust suction component, first, the bottom of the main pipe 1 is connected to the air filter inside the vehicle, and the air filter is connected to the engine intake end. The rain shield 2 located at the top of the main pipe 1 can prevent rainwater from entering the main pipe 1 on rainy days;
[0042] Then, during normal driving, when the vehicle does not pass through bumpy sections, the operation of the engine will use the intake end at the top of the main pipe 1 to suck air. Since the elastic rectifying plate 5 is made of a thin and light elastic material, and both the central column 3 and the sliding ring 9 are made of relatively light materials, when the air passes through the elastic rectifying plate 5, due to the filter holes evenly opened on the elastic rectifying plate 5, the dust in the air will be blocked on the upper surface of the elastic rectifying plate 5. As the dust on the upper surface of the elastic rectifying plate 5 increases and the fluidity decreases, under the driving action of the air, the spiral-structured elastic rectifying plate 5 will rotate by using the central column 3 to rotate on the rain shield 2. During the rotation process, since the sliding column 7 is stuck in the sliding groove 8, the central column 3 also drives the moving block 6 to rotate synchronously. The T-shaped slider 10 at the bottom of the moving block 6 then slides in the annular groove 101 on the inner wall of the sliding ring 9.
[0043] At this time, the counterweight ring 11 is in a static state and located on the limiting ring 13 at the bottom. Under the pulling action of the towing rope 12, the sliding ring 9 pulls the moving block 6 through the T-shaped slider 10, and the moving block 6 pulls the elastic rectifying plate 5 to deform. One end of the elastic rectifying plate 5 is fixed to the outer wall of the fixed rod 4, causing the elastic rectifying plate 5 to be stretched. The sliding column 7 on the outer wall of the moving block 6 is located at the bottom of the sliding groove 8;
[0044] Based on the above state, since the elastic rectifying plate 5 is inclined along the intake direction, a small amount of dust on the upper surface of the elastic rectifying plate 5 will fall to the outside along the airflow and the inclined surface into the groove formed between the outer side of the sliding ring 9 and the inner wall of the main pipe 1. At the same time, when the fluidity of the elastic rectifying plate 5 decreases and it rotates, a certain centrifugal force will be generated, making the dust on its upper surface easier to slide to the outside, preventing the elastic rectifying plate 5 from being blocked. Even when the dust moves along the upper surface of the elastic rectifying plate 5 to the end under the drive of the airflow, it can be guided to the edge of the elastic rectifying plate 5 by the inclined surface on the side wall of the moving block 6 and slide into the groove outside the sliding ring 9 for collection. Thus, while blocking the dust, the air flux of the elastic rectifying plate 5 is ensured, and most of the dust can be collected;
[0045] Finally, it is inevitable that the off-road vehicle will bump during driving. During the movement of the counterweight ring 11, the vehicle body will cause the counterweight ring 11 to slide on the outer wall of the main pipe 1 when bumping, and under the limit of the top limit ring 13, the moving distance of the counterweight ring 11 is short. During the sliding process of the counterweight ring 11, the pulling force of the traction rope 12 on the sliding ring 9 is released, so that the elastic rectifier plate 5 is deformed and reset, so that the sliding column 7 on the outer wall of the moving block 6 slides upward in the sliding groove 8, and the moving block 6 is driven to slide through the T-shaped slider 10. The ring 9 slides upward, and the dust in the groove is pushed upward while sliding. The thread on the outer wall of the bottom rod 20 drives the bottom rod 20 to rotate while sliding. The length of the slide groove 8 is limited so that the sliding distance of the sliding ring 9 is limited to the lower end of the outer edge of the sliding ring 9 being attached to the bottom of the shunt pipe 15. At the same time, the thread density on the bottom rod 20 is set so that when the sliding ring 9 moves to the highest point, the bottom rod 20 rotates ninety degrees, and the bottom rod 20 drives the valve plate 19 to rotate in the shunt pipe 15. The shunt pipe 15 After the conduction, part of the airflow will flow into the main pipeline 1 along the shunt pipe 15, the dust collecting cylinder 14 and the air outlet pipe 16, and the airflow will flow mixed with the dust collected in the groove outside the sliding ring 9. Through the inclined side design of the sliding ring 9, when the intake air contacts the inclined surface, the direction of the intake air will also be diverted to the intake end of the shunt pipe 15 under the compulsion of the inclined surface, so as to achieve the effect of diverting the intake air and discharging dust. During the flow, the dust is filtered through the filter plate 18 and retained on the upper surface of the filter plate 18. Even if the sliding ring 9 makes the collected dust The dust is slightly disturbed, but the valve plate 19 has rotated while the sliding ring 9 moves up. The dust collecting capacity can be increased by using the dust collecting mechanism with equal angle distribution. During regular maintenance, it is only necessary to open the sealing cover on the top of the dust collecting cylinder 14 to remove the filter plate 18 through the connecting column to clean the dust on the surface. The operation is convenient and can reduce the burden of the air filter. When the counterweight ring 11 slides down and resets, the sliding ring 9 slides down and resets under the action of the traction rope 12, and the bottom rod 20 rotates and resets, so that the valve plate 19 rotates and resets to close the shunt pipe 15.
[0046] During the bumping process, the counterweight ring 11 slides up and down, and the dust in the groove formed by the sliding ring 9 and the main pipe 1 can be continuously discharged from the main pipe 1 and collected.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
