Description

TECHNICAL FIELD

[0001] The application relates to the technical field of flux suction, in particular to a pressure distribution pipeline for flux suction, an air suction system and welding equipment. BACKGROUND

[0002] In the field of electronic manufacturing, surface mount technology (SMT) welding process is one of the key steps in producing printed circuit boards (PCBs). As one of the SMT welding processes, the welding quality of wave soldering directly affects the performance and reliability of PCB products. In the wave soldering process, the spraying of flux is a crucial step, which is responsible for cleaning the pads on the PCB and providing the necessary flux for welding.

[0003] The traditional flux spraying air suction system usually adopts a single hollow pipeline design, and the air suction effect is mainly concentrated in a small area near the pipeline opening. This design leads to low air suction efficiency and cannot effectively control the diffusion of flux, which makes the flux easy to overflow outside the production area and pollute the environment. At the same time, the problem of air suction port blockage also frequently occurs, which requires frequent cleaning and maintenance, not only increasing the operating cost, but also reducing the production efficiency. CONTENT OF THE INVENTION

[0011] In some embodiments, the first part comprises:

[0012] a negative pressure main chamber communicating with the negative pressure port;

[0013] a first negative pressure sub-chamber and a second negative pressure sub-chamber communicating with the negative pressure main chamber, the first negative pressure sub-chamber and the second negative pressure sub-chamber are located on both sides of the second part;

[0014] The first partition plate separates the first negative pressure sub-chamber and the second part, and the first partition plate separates the second negative pressure sub-chamber and the second part.

[0015] In some embodiments, the adsorption line groove is arranged in the length direction of the pipeline body, and in the width direction of the pipeline body, the first negative pressure sub-chamber and the second negative pressure sub-chamber are located on both sides of the second part.

[0016] In some embodiments, the first negative pressure sub-chamber and the second negative pressure sub-chamber are symmetrically arranged on both sides of the second part.

[0017] In some embodiments, the pressure distribution grid is further provided with a third partition plate, the third partition plate separates the second part into two rows of chambers, the first row of chambers communicates with the first negative pressure sub-chamber through the negative pressure hole, and the second row of chambers communicates with the second negative pressure sub-chamber through the negative pressure hole.

[0018] In some embodiments, the second partition plate is arc-shaped, the second partition plate smoothly transitions with the first partition plate, the second partition plate forms an arc-shaped chamber wall of the chamber, and the arc-shaped chamber wall curves away from the negative pressure port; and / or,

[0019] The pipeline body is cuboid-shaped.

[0020] In some embodiments, the pipeline body is provided with a mounting port communicating with the adsorption chamber, and the pressure distribution grid is mounted through the mounting port.

[0021] In some embodiments, the pressure distribution grid comprises:

[0022] a grid body slidingly assembled in the pipeline body;

[0023] a handle assembly arranged in the grid body, and when the grid body is assembled in the pipeline body, the handle assembly closes the mounting port.

[0024] The application also provides an air extraction system, comprising a driving device, an air extraction pipeline and the above-mentioned partial pressure pipeline for flux adsorption, which are sequentially connected.

[0025] The application also provides a welding device, comprising a welding machine and the above-mentioned air extraction system.

[0026] With respect to the above background technology, the partial pressure pipeline for flux adsorption provided by the application mainly comprises a pipeline main body and a partial pressure grid. The pipeline main body is internally provided with an adsorption cavity, and the surface of the pipeline main body is provided with a negative pressure port and an adsorption wire groove which are in communication with the adsorption cavity. The partial pressure grid is arranged in the adsorption cavity. The partial pressure grid is provided with a first partition plate which divides the adsorption cavity into a first part in communication with the negative pressure port and a second part in communication with the adsorption wire groove. The partial pressure grid is provided with a second partition plate which divides the second part into a plurality of chambers which are distributed along the length direction of the adsorption wire groove, and the chambers are in communication with the adsorption wire groove. The first partition plate is provided with a plurality of negative pressure holes which are correspondingly arranged with the chambers, and the negative pressure holes are in communication with the first part and the corresponding chambers. The plurality of negative pressure holes are arranged in a variable-diameter manner along the length direction of the adsorption wire groove, and the diameter of the negative pressure hole close to the negative pressure port is the smallest.

[0027] In the traditional flux spraying air extraction system, the air extraction effect is mainly concentrated in a small area near the pipeline port, resulting in low air extraction efficiency, which cannot effectively control the diffusion of flux, so that the flux is easy to overflow outside the production area and pollute the environment. In addition, the problem of blockage of the air extraction port also frequently occurs, which requires frequent cleaning and maintenance, which not only increases the operating cost, but also reduces the production efficiency.

[0028] In view of these problems, the partial pressure pipeline technical solution provided by the application realizes more uniform and efficient flux adsorption through innovative design. First, the pipeline main body is internally provided with an adsorption cavity, and the surface of the pipeline main body is provided with a negative pressure port and an adsorption wire groove which are in communication with the adsorption cavity. Such design enables the air extraction system to cover a wider area, thereby improving the air extraction efficiency.

[0029] Further, the partial pressure grid plays a key role in the adsorption cavity. The first partition plate divides the adsorption cavity into a first part in communication with the negative pressure port and a second part in communication with the adsorption wire groove. Such partition design enables the air extraction system to more effectively control the adsorption process of the flux. The second partition plate divides the second part into a plurality of chambers which are distributed along the length direction of the adsorption wire groove, so that the air extraction system can provide uniform adsorption force in the entire spraying area.

[0030] Most crucially, the first partition is provided with a plurality of negative pressure holes, which are correspondingly arranged with the chamber and through variable diameter design, so that the negative pressure hole close to the negative pressure port has the smallest diameter. Such design not only can ensure that the suction system provides uniform suction force on the entire length of the adsorption slot, but also can adjust the suction force according to the distance change, so as to realize more efficient flux adsorption.

[0031] Specifically, in the adsorption cavity, the gas first enters through the negative pressure holes with larger diameter, which are located away from the negative pressure port, so in this case the suction force of the negative pressure hole away from the negative pressure port is large; at the same time, close to the negative pressure port, the flow rate is large, which can produce greater negative pressure, so in this case the suction force of the negative pressure hole close to the negative pressure port is large; in combination with the above two cases, the suction force of the negative pressure hole is balanced by balancing the two cases, so as to realize the balance of the suction force of the chamber and the adsorption slot.

[0032] In combination with the above structure and process description, it can be seen that the pressure distribution pipeline for flux adsorption at least has the following beneficial effects: the pressure distribution pipeline for flux adsorption is designed through pressure distribution grid and variable diameter hole, which cooperates with longer adsorption slot to realize more uniform and efficient flux adsorption, effectively solving the problems of low efficiency and easy blockage of suction port of traditional suction system.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0043] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] Please refer to Figure 1 and Figure 2 wherein, Figure 1 a schematic diagram of a pressure distribution pipe for solder flux adsorption provided by the embodiments of the present application, Figure 2 a negative pressure flow direction diagram of the pressure distribution pipe for solder flux adsorption provided by the embodiments of the present application.

[0045] In a first specific embodiment, the pressure distribution pipe for solder flux adsorption provided by the embodiments of the present application mainly comprises a pipe body 1 and a pressure distribution grid 2.

[0046] The pipe body 1 is internally provided with an adsorption cavity 11, and the surface of the pipe body 1 is provided with a negative pressure port 12 and an adsorption line groove 13 in communication with the adsorption cavity 11.

[0047] The pressure distribution grid 2 is arranged in the adsorption cavity 11; the pressure distribution grid 2 is provided with a first partition 21, which divides the adsorption cavity 11 into a first part 201 in communication with the negative pressure port 12 and a second part 202 in communication with the adsorption line groove 13; the pressure distribution grid 2 is provided with a second partition 22, which divides the second part 202 into a plurality of cavities 23, which are distributed along the length direction of the adsorption line groove 13, and the cavities 23 are in communication with the adsorption line groove 13; the first partition 21 is provided with a plurality of negative pressure holes 24, which are arranged correspondingly to the cavities 23, the negative pressure holes 24 communicate the first part 201 and the corresponding cavities 23, and the plurality of negative pressure holes 24 are arranged in different diameters along the length direction of the adsorption line groove 13, and the diameter of the negative pressure hole 24 close to the negative pressure port 12 is the smallest.

[0048] In use, a negative pressure airflow is introduced into the pipeline body 1 through the negative pressure port 12, the negative pressure airflow is subjected to pressure division treatment by the pressure division grid 2, and is output through the adsorption line groove 13, thereby achieving adsorption of the flux on the board bottom of the PCB in the spraying area.

[0049] In the traditional flux spraying and air extraction system, the air extraction effect is mainly concentrated in a small area near the pipeline port, resulting in low air extraction efficiency, which cannot effectively control the diffusion of the flux, so that the flux is easy to overflow outside the production area and pollute the environment. In addition, the problem of blockage of the air extraction port also frequently occurs, which requires frequent cleaning and maintenance, which not only increases the operating cost, but also reduces the production efficiency.

[0050] To solve these problems, the pressure division pipeline technical solution provided by the present application realizes more uniform and efficient flux adsorption through innovative design. First, the pipeline body 1 is internally provided with an adsorption cavity 11, and the surface thereof is provided with a negative pressure port 12 and an adsorption line groove 13 in communication with the adsorption cavity 11. Such a design enables the air extraction system to cover a wider area, thereby improving the air extraction efficiency.

[0051] Further, the pressure division grid 2 is arranged in the adsorption cavity 11 and plays a key role. The first partition plate 21 divides the adsorption cavity 11 into a first part 201 in communication with the negative pressure port 12 and a second part 202 in communication with the adsorption line groove 13. Such a partition design enables the air extraction system to more effectively control the flux adsorption process. The second partition plate 22 divides the second part 202 into a plurality of chambers 23, which are distributed along the length direction of the adsorption line groove 13, so that the air extraction system can provide uniform adsorption force in the entire spraying area.

[0052] Most importantly, the first partition plate 21 is provided with a plurality of negative pressure holes 24, which are correspondingly arranged with the chambers 23 and are designed with variable diameters, so that the negative pressure holes 24 close to the negative pressure port 12 have the smallest diameter. Such a design not only ensures that the air extraction system provides uniform adsorption force along the entire length of the adsorption line groove 13, but also adjusts the adsorption force according to the distance, thereby realizing more efficient flux adsorption.

[0053] Specifically, in the adsorption cavity 11, the gas first enters through the negative pressure holes 24 with larger diameters, which are located away from the negative pressure port 12, so that the suction force of the negative pressure holes 24 away from the negative pressure port 12 is large in this case. At the same time, the flow rate is large near the negative pressure port 12, which will generate a larger negative pressure, so that the suction force of the negative pressure holes 24 close to the negative pressure port 12 is large in this case. In combination of the above two cases, the suction force of the negative pressure holes 24 is balanced by balancing the two cases, thereby balancing the suction force of the chambers 23 and the adsorption line groove 13.

[0054] In combination with the above structure and process, it can be seen that the pressure distribution pipeline for flux adsorption has at least the following beneficial effects: the pressure distribution pipeline for flux adsorption, through the design of the pressure distribution grid 2 and the variable-diameter round hole, in combination with the longer adsorption line groove 13, achieves more uniform and efficient flux adsorption, effectively solving the problems of low efficiency and easy clogging of the air suction port of the traditional air suction system.

[0055] In some cases, the orientation in Figure 2 , the negative pressure port 12 is located on the left, the adsorption line groove 13 is located on the right and extends to the right, the main part of the first part 201 is located on the left, the second part 202 is located on the right, the chambers 23 are distributed from left to right, the negative pressure holes 24 correspond one-to-one to the chambers 23, and the negative pressure holes 24 are also distributed from left to right. In the direction to the right, the hole diameter of the negative pressure holes 24 increases, the hole diameter of the negative pressure holes 24 on the left is the smallest, and the hole diameter of the negative pressure holes 24 on the right is the largest.

[0056] In Figure 2 , for the direction of the negative pressure airflow, it is in turn the negative pressure port 12, the first part 201, the first partition 21, the second part 202, and the adsorption line groove 13. Specifically, after the first part 201, it is in turn the negative pressure holes 24, the chambers 23, and the adsorption line groove 13.

[0057] Please refer to Figures 3 to 6 , wherein, Figure 3 is a top view of the pipeline body provided by the embodiment of the application, Figure 4 is a front view of the pipeline body provided by the embodiment of the application, Figure 5 is a top view of the pressure distribution grid provided by the embodiment of the application, Figure 6 is a front view of the pressure distribution grid provided by the embodiment of the application.

[0058] In some embodiments, the first part 201 includes:

[0059] the negative pressure main cavity 2011, which communicates with the negative pressure port 12;

[0060] the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013, which communicate with the negative pressure main cavity 2011, and are located on the two sides of the second part 202;

[0061] The first partition 21 separates the first negative pressure sub-cavity 2012 and the second part 202, and the first partition 21 separates the second negative pressure sub-cavity 2013 and the second part 202.

[0062] In this embodiment, the technical solution of the pressure distribution pipeline optimizes the adsorption efficiency of the flux through the careful design of the internal structure. Specifically, the first part 201 is composed of a negative pressure main cavity 2011, a first negative pressure sub-cavity 2012, and a second negative pressure sub-cavity 2013. The negative pressure main cavity 2011 is directly connected to the negative pressure port 12, ensuring that the airflow introduced from the negative pressure port 12 can directly enter the negative pressure main cavity 2011, thereby forming a stronger adsorption force in this area.

[0063] The first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013 are located on both sides of the second part 202, so that Figure 2 For example, the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013 are located on the front and back sides of the second part 202. This layout helps to achieve balanced distribution of adsorption force inside the entire pipeline. By separating these two negative pressure sub-cavities from the second part 202 through the first partition 21, the gas flow path and the distribution of adsorption force can be more accurately controlled. Such a design not only helps to improve the adsorption efficiency, but also helps to prevent the blockage of the suction port, as the gas and flux can be more evenly guided through the entire system.

[0064] In some embodiments, the adsorption line groove 13 is arranged to extend in the length direction of the pipeline body 1, and in the width direction of the pipeline body 1, the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013 are located on both sides of the second part 202.

[0065] In this embodiment, the adsorption line groove 13 is designed to extend along the length direction of the pipeline body 1. Such a layout helps to cover a wider area, thereby improving the adsorption capacity of the entire pipeline. By symmetrically arranging the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013 in the width direction of the pipeline body 1, the cross section of the pipeline body 1 is fully utilized, and the adsorption force on both sides is ensured to be uniform.

[0066] This design enables the adsorption line groove 13 to more effectively capture and adsorb flux particles that diffuse out during the flux spraying process, reducing their diffusion in the workshop and thus reducing environmental pollution and potential threats to the health of operating personnel. At the same time, due to the symmetrical layout of the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013, it can be expected that the adsorption performance on both sides of the pipeline body 1 is balanced, which helps to maintain the stability and reliability of the entire system.

[0067] In addition, the cooperation of the adsorption line groove 13 with the first negative pressure sub-cavity 2012 and the second negative pressure sub-cavity 2013 not only improves the adsorption efficiency, but also helps to reduce the possibility of system blockage. This is because the adsorption line groove 13 covers a wider area, and flux particles are more easily adsorbed rather than accumulated at the suction port to cause blockage. Therefore, this design not only improves the performance of the system, but also reduces maintenance costs and complexity.

[0068] In some embodiments, the first negative pressure sub-chamber 2012 and the second negative pressure sub-chamber 2013 are symmetrically arranged on both sides of the second part 202.

[0069] In this embodiment, the first negative pressure sub-chamber 2012 and the second negative pressure sub-chamber 2013 are symmetrically arranged on both sides of the second part 202, and this symmetrical layout helps to achieve balanced distribution of adsorption force inside the entire pipeline. By arranging symmetrical negative pressure sub-chambers in the width direction of the pipeline body 1, it can ensure that the adsorption efficiency on both sides is consistent, thereby improving the overall adsorption performance.

[0070] The symmetrically arranged first negative pressure sub-chamber 2012 and the second negative pressure sub-chamber 2013, in combination with the adsorption line groove 13, can more effectively control the flow and adsorption of flux. This design allows the airflow to be evenly distributed into the two negative pressure sub-chambers when passing through the adsorption line groove 13, thereby achieving more uniform adsorption effect across the entire pipeline cross-section.

[0071] In addition, the symmetrical layout also helps to reduce the instability of the system caused by structural asymmetry, improving the reliability and durability of the system. In actual application, this design can reduce the problem of flux residue or insufficient suction caused by excessive or insufficient local adsorption force, ensuring that the flux generated during welding can be effectively controlled and processed.

[0072] In some embodiments, the pressure distribution grid 2 is also provided with a third partition plate 25, which divides the second part 202 into two rows of chambers 23. The first row of chambers 23 communicates with the first negative pressure sub-chamber 2012 through the negative pressure hole 24, and the second row of chambers 23 communicates with the second negative pressure sub-chamber 2013 through the negative pressure hole 24.

[0073] In this embodiment, the pressure distribution grid 2 realizes further optimization of the space of the second part 202 by adding the third partition plate 25. The third partition plate 25 divides the second part 202 into two rows of chambers 23, so that Figure 2 For example, there is a row of chambers 23 close to the first negative pressure sub-chamber 2012 to the rear, and a row of chambers 23 close to the second negative pressure sub-chamber 2013 to the front. This design makes the layout of the chambers 23 more reasonable, improves the space utilization rate, and enhances the adsorption efficiency of the entire system.

[0074] In some embodiments, the second partition plate 22 is arc-shaped, the second partition plate 22 is smoothly transitioned with the first partition plate 21, the second partition plate 22 constitutes an arc-shaped chamber wall 231 of the chamber 23, and the arc-shaped chamber wall 231 is curved towards the direction away from the negative pressure port 12.

[0075] In this embodiment, the second partition 22 adopts an arc-shaped design, achieving a smooth transition with the first partition 21 and forming an arc-shaped cavity wall 231 of the cavity 23. This design not only makes the internal structure of the cavity 23 more fluent, optimizing the path of gas flow, but also bends the arc-shaped cavity wall 231 towards the direction away from the negative pressure port 12, helping to more evenly distribute the adsorption force. Such a design makes the adsorption effect of the entire cavity 23 more consistent, improving the adsorption efficiency of the entire air extraction system.

[0076] The design of the arc-shaped cavity wall 231 also helps to optimize the gas flow characteristics, reducing turbulence and vortex during gas flow, thereby reducing energy loss and improving the efficiency of the air extraction system. In addition, the arc-shaped structure can guide the gas to flow more smoothly, reducing the resistance of gas flow, so that the gas can pass through the cavity 23 more quickly, improving the response speed and adsorption capacity of the system.

[0077] The arc-shaped cavity wall 231 also helps to reduce the deposition of flux particles in the cavity, as the arc-shaped design reduces corners and right-angle structures, which reduces the risk of system blockage and simplifies maintenance and cleaning work. At the same time, the arc-shaped structure has good stability in mechanics and can withstand greater pressure without deformation, which helps to improve the durability and reliability of the entire pressure reduction pipeline, ensuring long-term stable operation of the entire system.

[0078] In some embodiments, the pipeline body 1 is in the shape of a cuboid.

[0079] In this embodiment, the pipeline body 1 adopts a cuboid shape, which provides a stable and structured space for the entire pressure reduction pipeline. The cuboid shape helps to maximize the internal volume of the pipeline body 1, thereby providing sufficient space for key components such as the adsorption cavity 11, the negative pressure port 12, and the adsorption line groove 13.

[0080] The geometric characteristics of the cuboid make the dimensions of the pipeline body 1 in each direction can be precisely controlled, which helps to optimize the distribution of internal airflow and the pressure field in the adsorption cavity 11. In addition, the cuboid design also simplifies the manufacturing and assembly process of the pipeline body 1, as the straight edges and right-angle connections of the cuboid are easier to achieve through standardized manufacturing techniques.

[0081] The cuboid shape of the pipeline body 1 also helps to improve the stability and durability of the entire system. The symmetry and uniform distribution of stress of the cuboid help the pipeline to withstand the pressure changes during the air extraction process, thereby reducing the risk of structural deformation. This shape also facilitates the docking and integration of the pipeline body 1 with other system components, for example, it can be easily connected with external air extraction pipelines and driving devices.

[0082] In some embodiments, the pipe body 1 is provided with a mounting port 14 that is in communication with the adsorption cavity 11, through which the partial pressure grid 2 is installed.

[0083] In this embodiment, the pipe body 1 is specifically designed with a mounting port 14, which primarily functions to communicate with the adsorption cavity 11 and allow the installation and assembly of the partial pressure grid 2. This design simplifies the installation process of the partial pressure grid 2, making maintenance and replacement work easier and faster.

[0084] Through the mounting port 14, the partial pressure grid 2 can be directly placed or fixed within the adsorption cavity 11, ensuring the correct alignment and installation between the partial pressure grid 2 and the pipe body 1. Such a design also helps to protect the partial pressure grid 2 from damage during installation, while also ensuring the air tightness of the entire partial pressure piping system.

[0085] In addition, the presence of the mounting port 14 also provides additional flexibility for the pipe body 1, allowing it to adapt to different installation requirements and conditions. For example, if adjustments or replacements need to be made to the partial pressure grid 2, it can be quickly done through the mounting port 14 without the need to disassemble the entire piping system, greatly reducing maintenance time and cost.

[0086] In some embodiments, the partial pressure grid 2 comprises:

[0087] A grid body 26 that is slidingly assembled in the pipe body 1, on which the first partition 21, the second partition 22, and the third partition 25 are arranged;

[0088] A handle assembly 27 provided on the grid body 26, which closes the mounting port 14 when the grid body 26 is assembled in the pipe body 1.

[0089] In this embodiment, the partial pressure grid 2 is composed of the grid body 26 and the handle assembly 27, where the grid body 26 is responsible for carrying the first partition 21, the second partition 22, and the third partition 25. These partitions collectively form the core structure of the partial pressure grid 2, responsible for dividing the adsorption cavity 11 into different functional areas to achieve more effective airflow distribution and flux adsorption.

[0090] The grid body 26 is installed in the pipe body 1 using a sliding assembly method, which allows the grid body 26 to move flexibly within the pipe body 1, facilitating installation and maintenance. The sliding assembly method also means that the partial pressure grid 2 can be easily adjusted or replaced without the need for complex modifications to the pipe body 1.

[0091] The handle assembly 27 is a part of the grid body 26, which plays a role in closing the installation port 14 after the grid body 26 is installed to the pipeline body 1. This design not only ensures the air tightness of the entire system, preventing external air interference, but also provides a convenient operation point, making the installation and removal of the pressure distribution grid 2 more convenient.

[0092] Through this design, the pressure distribution grid 2 can accurately control the negative pressure in different areas of the adsorption cavity 11, thereby optimizing the performance of the entire exhaust system. At the same time, the modular design of the pressure distribution grid 2 also improves the maintainability and upgradability of the entire system, making the system adaptable to future possible improvements and expansion needs.

[0093] The application also provides an exhaust system, comprising a driving device, an exhaust pipeline, and the above-mentioned pressure distribution pipeline for flux adsorption, the driving device, the exhaust pipeline, and the pressure distribution pipeline for flux adsorption are connected in sequence.

[0094] The exhaust system should have all the beneficial technical effects of the above-mentioned pressure distribution pipeline for flux adsorption, which will not be repeated here.

[0095] In this embodiment, the provided exhaust system is composed of three main parts: a driving device, an exhaust pipeline, and a pressure distribution pipeline for flux adsorption. The driving device usually adopts a centrifugal pump, which is widely used in exhaust systems due to its high efficiency and stable characteristics.

[0096] The working principle of the centrifugal pump is to generate centrifugal force through the rotation of the impeller inside the pump, thereby pumping liquid or gas from a low-pressure area to a high-pressure area, thereby providing a negative pressure airflow. In the exhaust system, the centrifugal pump provides sufficient power to effectively remove flux vapor and other contaminants from the welding area through the pressure distribution pipeline.

[0097] The exhaust pipeline connects the driving device and the pressure distribution pipeline, forming the channel of the entire exhaust system.
