Description

Technical Field

[0001] The present invention belongs to the technical field of automobile exhaust pipes, and particularly relates to a multifunctional automobile exhaust pipe. Background Art

[0002] The automobile exhaust pipe is a key component of the automobile exhaust system. It is responsible for guiding the exhaust gas generated by the engine to the outside of the vehicle and ensuring that this process is as efficient and safe as possible. In the existing patent text with the publication number CN210599152U, an automobile tail pipe with a gas filtering function is disclosed, which includes an inner exhaust pipe. One end of the inner exhaust pipe is fitted with a pipe wall, and the other end of the inner exhaust pipe is provided with liquid. One side of the upper end of the pipe wall is fixedly connected with a liquid inlet pipe. By setting up a liquid inlet pipe, liquid and a liquid discharge pipe for liquid circulation, it can effectively filter the high-temperature and high-heat harmful solid particles in the automobile exhaust gas, improve the quality of exhaust gas emissions. By setting up a coarse filter screen and a fine filter screen in cooperation, it can effectively filter the small amount of solid particles that fail to precipitate in the exhaust gas. By setting up an activated carbon column, it can adsorb the harmful substances in the exhaust gas. The functions of the existing disclosed exhaust pipes are relatively single. The intake air flow of the exhaust pipe cannot be automatically adjusted, and it cannot effectively adapt to the working states with different intake air volumes, resulting in poor versatility. At the same time, the exhaust gas flow diffusion of the existing exhaust pipes is not sufficient enough, so that the exhaust gas cannot fully contact the activated carbon column and the filter screen, and the exhaust gas filtering effect is poor. Therefore, it is necessary to design a multifunctional automobile exhaust pipe to overcome the above difficulties. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the present invention designs a multifunctional automobile exhaust pipe. The present invention is provided with a flow regulating component in the inner core intake pipe of the main housing, which is convenient for adapting to the working states with different flow rates. Cooperating with the one-way valve component, the exhaust gas automatically discharges from the outlet pipe, and has good versatility. During the process of exhaust gas discharge, it is fully filtered by the filtering component, and has a good filtering effect.

[0004] The invention object of the present invention is realized by the following technical solutions: A multifunctional automobile exhaust pipe includes a main housing. The main housing is internally provided with a first chamber, a second chamber and a third chamber which are arranged adjacent to each other in sequence. The first chamber is internally provided with an inner core intake pipe, and a flow regulating component is installed on the inner core intake pipe. An outlet pipe is provided in the main housing.

The initial end of the first inner core pipe is arranged in the first chamber, and the end of the first inner core pipe is installed on the inner wall of the second chamber. The third chamber is filled with sound-absorbing cotton, and a filtering component facing the second chamber is provided in the sound-absorbing cotton.

[0005] Preferably, a first partition is provided between the first chamber and the second chamber, and a second partition is provided between the second chamber and the third chamber; an inner core transverse partition is fixedly installed at the end of the first partition facing the first chamber, and an inner core intake pipe is fixedly installed on the inner core transverse partition; the first inner core pipe is bent, one end of the first inner core pipe is inserted through the first partition, and the other end of the first inner core pipe is fitted and installed on the first partition; the air outlet pipe sequentially passes through the first partition and the second partition, and the sound-absorbing cotton is wrapped around the outer layers of the air outlet pipe and the first inner core pipe.

[0006] Preferably, a plurality of uniformly distributed air-permeable holes are provided on the inner core intake pipe, the first inner core pipe and the air outlet pipe, and a plurality of air-permeable holes are also provided on the second partition; a first channel for installing the first inner core pipe is provided on the sound-absorbing cotton, and the outer contour of the first channel is adapted to the outer contour of the first inner core pipe; a second channel for installing the air outlet pipe is further provided on the sound-absorbing cotton, and the outer contour of the second channel is adapted to the outer contour of the air outlet pipe; the air-permeable holes on the air outlet pipe are arranged close to the third chamber; a plurality of reinforcing ribs for fixing the two are provided between the first partition and the second partition.

[0007] A plurality of uniformly distributed air-permeable holes are provided on the inner core intake pipe, the first inner core pipe and the air outlet pipe, and a plurality of air-permeable holes are also provided on the second partition; the aperture of the air-permeable holes is small, which is convenient for changing the air intake mode; when the air flow rate is small, the air flow first enters the first chamber from the inner core intake pipe. At this time, the impact force of the air flow is small, and the one-way valve assembly is in a closed state; then the air flow will sequentially pass through the second chamber and the third chamber, and the air flow is silenced by the sound-absorbing cotton in the third chamber and fully filtered by the filter assembly; then the air flow returns to the first chamber along the first inner core pipe. At this time, the gas is compressed, and the one-way valve assembly is opened by the impact of the air flow, and then the air flow is discharged from the air outlet pipe. When the air flow rate is large, a part of the air flow enters the first chamber from the inner core intake pipe, then the air flow circulates to the second chamber and the third chamber along the first inner core pipe, then returns to the first chamber along the first inner core pipe, and is then discharged through the one-way valve assembly; another part of the air flow is directly discharged from the one-way valve assembly in the first chamber; therefore, through the air intake mode diffused by the air-permeable holes, the working state of various flow rates can be adapted, and the versatility is good. A first channel for installing the first inner core pipe is provided on the sound-absorbing cotton, and the outer contour of the first channel is adapted to the outer contour of the first inner core pipe; a second channel for installing the air outlet pipe is further provided on the sound-absorbing cotton, and the outer contour of the second channel is adapted to the outer contour of the air outlet pipe; in this way, the sound-absorbing cotton is in full contact with the first inner core pipe and the air outlet pipe, and the sound-absorbing effect is better.

[0008] Preferably, a first annular baffle perpendicular to the inner wall of the inner core intake pipe is provided on the inner wall of the inner core intake pipe, and a flow rate regulating assembly is provided on the inner core intake pipe; the flow rate regulating assembly includes an adjusting knob and a driving motor, the adjusting knob is rotatably connected to the inner core intake pipe, and when the driving motor operates, it drives the adjusting knob to rotate relative to the first annular baffle; a flow rate monitoring assembly is provided below the flow rate regulating assembly, and the flow rate monitoring assembly is disposed close to the first chamber.

[0009] Preferably, the flow rate regulating assembly further includes a first gear and a second gear, the adjusting knob includes a rotating shaft body and a second annular baffle, and the rotating shaft body and the second annular baffle are integrally formed; the flow rate regulating assembly further includes a mounting housing, and the mounting housing is disposed on the outer wall of the main housing; a driving motor is fixedly mounted on the mounting housing, a first gear is provided on the motor shaft of the driving motor, and a second gear synchronously rotating with it is provided on the rotating shaft body; the first gear and the second gear are meshed with each other, and when the driving motor operates, it drives the rotating shaft body to rotate.

[0010] Preferably, a first card slot is provided on the end face of the rotating shaft body facing the mounting housing, and a magnet is installed in the first card slot; two annularly distributed Hall sensors are provided on the inner wall of the mounting housing, and the included angle between the two Hall sensors is 90 degrees; in the default state, the second annular baffle is vertically disposed, and the magnet is disposed close to the Hall sensor in the lower position.

[0011] Preferably, the flow rate regulating assembly includes a magnetic rotor, an induction circuit board, and a pair of annular mounting brackets; the annular mounting brackets are respectively fixedly mounted adjacent to each other inside the inner core intake pipe, and the rotating shafts of the magnetic rotor are respectively mounted on the annular mounting brackets adjacent to it; a first partition is provided between the first chamber and the second chamber, and an inner core transverse partition is fixedly mounted on the first partition; a protective housing is provided on the inner core transverse partition, and the protective housing extends along the first chamber towards the outer wall of the main housing; an induction circuit board is provided inside the protective housing, and a wiring terminal electrically connected to it is provided on the induction circuit board, and the wiring terminal extends towards the outside of the main housing along the axial direction of the protective housing; the induction circuit board faces the magnetic rotor, and a transparent cover plate is provided on the inner wall of the protective housing close to the induction circuit board, and the transparent cover plate is fixedly connected to the protective housing; the magnetic rotor includes N poles and S poles alternately arranged in sequence, and both the N poles and S poles are provided in pairs.

[0012] The vehicle is equipped with a main control module, and the main control module is electrically connected to a drive motor, a Hall sensor, and an induction circuit board; in the default state, the opening of the inner core intake pipe is the largest, and at this time, the second annular baffle and the first annular baffle are perpendicular to each other; at this time, the magnet approaches the Hall sensor in the low position; when the flow rate needs to be adjusted, the main control module controls the drive motor to rotate, the drive motor drives the first gear to rotate, and when the first gear rotates, the second gear rotates, so that the rotating shaft body can drive the second annular baffle to rotate; since a flow rate monitoring component is provided below the flow rate adjustment component, the flow rate data can be displayed in real time on the main control module, which is convenient for the user to automatically adapt and adjust the flow rate. As the rotating shaft body rotates, the magnet approaches the Hall sensor in the high position. At this time, the Hall sensor in the high position sends an electrical signal to the main control module, and the main control module controls the drive motor to rotate in the reverse direction to prevent the second annular baffle from interfering with the first annular baffle; when the magnet moves from the high position to a position lower than it, the magnet will eventually approach the Hall sensor in the low position, so that the Hall sensor in the low position sends an electrical signal to the main control module, and the main control module controls the drive motor to rotate in the reverse direction again; therefore, by setting the Hall sensor, it is convenient to control the rotation angle of the second annular baffle.

[0013] When the air flow enters the inner core intake pipe, the flow rate monitoring component starts to work; when the air flow impacts the magnetic rotor, the magnetic rotor can rotate relative to the annular mounting bracket; since the magnetic rotor includes N poles and S poles arranged alternately in sequence, different electrical signals will be generated when the N poles and S poles approach the induction circuit board; the induction circuit board sends the electrical signal to the main control module. Since the cross-sectional area of the inner core intake pipe remains fixed, the main control module can calculate the number of rotations of the magnetic rotor through the conversion of the electrical signal; a timer is built into the main control module, so the main control module can calculate the gas flow rate per unit time. The user can adapt and adjust the flow rate according to the real-time flow rate data of the air flow through the flow rate adjustment component.

[0014] Preferably, an annular card slot is provided in the sound-absorbing cotton, and a filtering component is installed in the annular card slot; the filtering component includes a filtering housing, a heat-insulating ring, an activated carbon ring, and a number of uniformly distributed spiral activated carbons; the filtering housing is installed in the annular card slot, a heat-insulating ring is installed in the filtering housing, a cross baffle is fixedly installed in the heat-insulating ring, and the spiral activated carbons are arranged between the cross baffle and the bottom wall of the filtering housing; an activated carbon ring is arranged in the heat-insulating ring, and the activated carbon ring axially extends from the cross baffle to the bottom wall of the filtering housing.

[0015] Preferably, a wind blade rotatably connected thereto is further provided inside the heat insulation ring, and paired guiding brackets are fixedly installed inside the heat insulation ring; an annular step is provided at the open end of the heat insulation ring, one of the guiding brackets is installed on the annular step, and the other guiding bracket is installed on the cross baffle; a wind blade is provided between the two guiding brackets, and the rotating shaft of the wind blade is rotatably connected to the guiding bracket; a plurality of guiding plates are provided on the guiding bracket and are arranged in a circumferential array, and the end face of the guiding plate is inclined with respect to the heat insulation ring.

[0016] When the air flow enters the first chamber from the inner core air inlet pipe, the air flow will diffuse along the first inner core pipe to the second chamber and the third chamber; when the air flow diffuses to the third chamber, the air flow will impact the wind blade, and the wind blade rotates relative to the guiding bracket; by providing the guiding plate, it is convenient to guide the air flow, so that the air flow is concentrated and diffused inside the filter housing; the air flow is driven by the wind blade to diffuse, and the overall flow rate of the air flow is faster, so the contact effect between the air flow and the spiral activated carbon is better; the spiral activated carbon and the activated carbon ring are provided inside the filter housing, so that the air flow can fully contact the spiral activated carbon and the activated carbon ring, and the filtering effect is better. By providing the annular step and the cross baffle, it is convenient to position and install the guiding bracket; by providing the heat insulation ring, the heat insulation effect is better.

[0017] Preferably, the one-way valve assembly includes a valve body, an end cover, a blocking member and a return torsion spring; the valve body is connected to the initial end of the air outlet pipe, and an end cover is sleeved and installed on the open end of the valve body; a ventilation port is provided on the end cover, and a blocking member rotatably connected thereto is provided inside the end cover; a pin shaft for pivotally connecting the two is provided between the blocking member and the end cover, and a return torsion spring is sleeved and installed on the pin shaft; one pin of the return torsion spring abuts against the end cover, and the other pin of the return torsion spring passes through the bottom of the end cover.

[0018] In the default state, the blocking member abuts against the ventilation port of the end cover, and at this time the one-way valve assembly is in a closed state; due to the elastic force of the return torsion spring, the blocking member can reliably seal the ventilation port; when the air flow rate in the first chamber is large, the gas is compressed; then the air flow will overcome the elastic force of the return torsion spring, so that the blocking member moves away from the ventilation port, and at this time the one-way valve assembly is in an open state. When no air enters the first chamber, the return torsion spring controls the blocking member to automatically reset, and the one-way valve assembly will automatically close.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. By providing the first chamber, the second chamber and the third chamber, it is convenient for the air flow to exchange in the main housing, so that the air flow is fully filtered by the filter assembly, and after the air flow is treated by the sound-absorbing cotton, the sound-absorbing effect is better when it is discharged from the air outlet pipe; 2. By providing a flow regulation assembly in the inner core air inlet pipe, it is convenient for users to adjust the flow rate according to the actual working conditions, and the versatility is good; 3. The flow monitoring assembly can reliably test the real-time data of the intake air flow and intuitively feedback it to the user; in this way, it is convenient for the user to adjust the intake air flow through the flow regulation assembly; 4. By cooperating the one-way valve assembly with the flow regulation assembly, different working states with different flow rates can be adapted, and the versatility is good; 5. The air flow is driven by the fan blade in the filter assembly to accelerate the diffusion, so that the exhaust gas can fully contact the spiral activated carbon and the activated carbon ring, and the filtering effect is better.

[0040] The specific operation process of this embodiment is as follows. In the default state, the blocking member 83 abuts against the ventilation port 85 of the end cap 82, and at this time, the one-way valve assembly 8 is in the closed state; due to the elastic force of the return torsion spring 84, the blocking member 83 can reliably seal the ventilation port 85; when the gas flow rate in the first chamber 2 is large, the gas is compressed; then the air flow will overcome the elastic force of the return torsion spring 84, so that the blocking member 83 moves away from the ventilation port 85, and thus the one-way valve assembly 8 is in the open state. When no more gas enters the first chamber 2, the return torsion spring 84 controls the blocking member 83 to automatically reset, and thus the one-way valve assembly 8 will automatically close. A number of uniformly distributed ventilation holes are provided on the inner core intake pipe 5, the first inner core pipe 10, and the outlet pipe 7; a number of ventilation holes are also provided on the second partition plate 13; the aperture of the ventilation holes is small, which is convenient for changing the air intake mode; when the gas flow rate is small, the air flow first enters the first chamber 2 from the inner core intake pipe 5. At this time, the impact force of the air flow is small, and the one-way valve assembly 8 is in the closed state; then the air flow will pass through the second chamber 3 and the third chamber 4 in sequence. The air flow is silenced by the sound-absorbing cotton 11 in the third chamber 4 and is fully filtered by the filter assembly 9; then the air flow returns to the first chamber 2 along the first inner core pipe 10. At this time, the gas is compressed, and the one-way valve assembly 8 is in the open state due to the impact of the air flow, and then the air flow is discharged from the outlet pipe 7. When the gas flow rate is large, a part of the air flow enters the first chamber 2 from the inner core intake pipe 5, then the air flow flows along the first inner core pipe 10 to the second chamber 3 and the third chamber 4, then returns to the first chamber 2 along the first inner core pipe 10, and is then discharged through the one-way valve assembly 8; another part of the air flow is directly discharged from the one-way valve assembly 8 in the first chamber 2; therefore, through the air intake mode of diffusion through the ventilation holes, the working states of various flow rates can be adapted, and the versatility is good. The sound-absorbing cotton 11 is provided with a first channel 111 for installing the first inner core pipe 10, and the outer contour of the first channel 111 is adapted to the outer contour of the first inner core pipe 10; the sound-absorbing cotton 11 is also provided with a second channel 112 for installing the outlet pipe 7, and the outer contour of the second channel 112 is adapted to the outer contour of the outlet pipe 7; in this way, the sound-absorbing cotton 11 is in full contact with the first inner core pipe 10 and the outlet pipe 7, and the sound-absorbing effect is better.

[0041] The vehicle is equipped with a main control module, and the main control module is electrically connected to the drive motor 62, the Hall sensor 67, and the induction circuit board 162. In the default state, the opening of the inner core intake pipe 5 is the largest, and at this time, the second annular baffle 612 and the first annular baffle 51 are perpendicular to each other. At this time, the magnet 66 is close to the Hall sensor 67 in the low position. When the flow rate needs to be adjusted, the main control module controls the drive motor 62 to rotate. The drive motor 62 drives the first gear 63 to rotate. When the first gear 63 rotates, the second gear 64 rotates, so that the rotating shaft body 611 can drive the second annular baffle 612 to rotate. Since the flow rate monitoring component 16 is provided below the flow rate adjustment component 6, the flow rate data can be displayed in real time on the main control module, which is convenient for the user to automatically adapt and adjust the flow rate. As the rotating shaft body 611 rotates, the magnet 66 approaches the Hall sensor 67 in the high position. At this time, the Hall sensor 67 in the high position sends an electrical signal to the main control module, and the main control module controls the drive motor 62 to rotate in the reverse direction, so as to prevent the second annular baffle 612 from interfering with the first annular baffle 51. When the magnet 66 approaches from the high position to a position lower than, the magnet 66 will eventually approach the Hall sensor 67 in the low position. At this time, the Hall sensor 67 in the low position sends an electrical signal to the main control module, and the main control module controls the drive motor 62 to rotate in the reverse direction again. Therefore, by setting the Hall sensor 67, it is convenient to control the rotation angle of the second annular baffle 612.

[0042] When the air flow enters the inner core intake pipe 5, the flow rate monitoring component 16 starts to work. When the air flow impacts the magnetic rotor 161, the magnetic rotor 161 can rotate relative to the annular mounting bracket 163. Since the magnetic rotor 161 includes N poles 165 and S poles 166 arranged alternately in sequence, different electrical signals will be generated when the N poles 165 and S poles 166 approach the induction circuit board 162. The induction circuit board 162 sends the electrical signal to the main control module. Since the cross-sectional area of the inner core intake pipe 5 remains fixed, the main control module can calculate the number of rotations of the magnetic rotor 161 through the conversion of the electrical signal. A timer is built into the main control module, so the main control module can calculate the gas flow rate per unit time. The user can adapt and adjust the flow rate according to the real-time flow rate data of the air flow through the flow rate adjustment component 6.

[0043] When the air flow enters the first chamber 2 from the inner core air inlet pipe 5, the air flow will diffuse along the first inner core pipe 10 into the second chamber 3 and the third chamber 4; when the air flow diffuses into the third chamber 4, the air flow will impact the wind blade 96, and the wind blade 96 rotates relative to the guiding bracket 97; by arranging the guiding plate 99, it is convenient to guide the air flow, so that the air flow is concentrated and diffused inside the filter housing 91; the air flow is driven by the wind blade 96 to diffuse, and the overall flow rate of the air flow is faster, so the contact effect between the air flow and the spiral activated carbon 94 is better; the filter housing 91 is internally provided with the spiral activated carbon 94 and the activated carbon ring 93, so that the air flow can fully contact the spiral activated carbon 94 and the activated carbon ring 93, and the filtering effect is better. By arranging the annular step 98 and the cross baffle 95, it is convenient to position and install the guiding bracket 97; by arranging the heat insulation ring 92, the heat insulation effect is better.
