[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0066] Vehicle exhaust systems typically utilize heaters 200 to heat exhaust gases before they enter the catalyst, thereby reducing the content of harmful substances in vehicle exhaust gases under cold start conditions. In related technologies, a heater 200 is installed inside the vehicle exhaust pipe 100 to heat the exhaust gases under cold start conditions. Regardless of whether the exhaust gases are heated, they continuously pass through the heater 200, which operates under high temperature and high pressure for extended periods. Furthermore, as the exhaust gas temperature rises, the heater 200 remains in a high-efficiency operating state, and the excess heat from the heater 200 also keeps it under high temperature and high pressure. This can cause the heater 200 to easily deform, leading to short circuits. Simultaneously, acidic substances in the exhaust gases further accelerate the aging of the heater 200, shortening its lifespan.

[0067] To address the problems of the heater 200 mentioned above, this application provides an exhaust gas treatment system 10. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 5 , Figure 1 This is a schematic diagram of a vehicle 20 equipped with an exhaust gas treatment system 10 provided in an exemplary embodiment of this disclosure; Figure 3 This is a schematic diagram of the structure of the diversion component 300 in the exhaust gas treatment system 10 provided in the exemplary embodiment of this disclosure; Figure 4 This is a cross-sectional view of the hydraulic converter 313 of the diversion assembly 300 provided in an exemplary embodiment of this disclosure; Figure 5 This is a partial cross-sectional view of the heater 200 provided in an exemplary embodiment of this disclosure, installed within the second tube 160.

[0068] An exhaust gas treatment system 10 includes an exhaust pipe 100, a heater 200, and a first monitoring and control device. The exhaust pipe 100 includes an inlet end 110 and an exhaust end 120, and the heater 200 is installed inside the exhaust pipe 100 between the inlet end 110 and the exhaust end 120. The heater 200 is connected to the first monitoring and control device, which is configured to adjust the operating state of the heater 200 based on monitored current operating information of the heater 200 when exhaust gas is discharged through the heater 200.

[0069] When exhaust gas passes through heater 200, the first monitoring and control device automatically adjusts the operating status of heater 200 based on the monitored current operating information. For example, it increases the operating power of heater 200 when the exhaust gas temperature is insufficient and decreases the operating power when the exhaust gas temperature is too high. This ensures that heater 200 operates under optimal conditions, thereby improving the efficiency of exhaust gas treatment and reducing harmful emissions.

[0070] In some embodiments, the discharge pipe 100 includes an inlet end 110 and an exhaust end 120, as well as a first channel 130 and a second channel 140 connected in parallel between the inlet end 110 and the exhaust end 120, and a heater 200 is disposed in the second channel 140.

[0071] In this embodiment of the application, a first channel 130 and a second channel 140 are provided in parallel between the air inlet end 110 and the exhaust end 120, and the heater 200 is disposed in the second channel 140 to facilitate the installation of the heater 200.

[0072] In some embodiments, a diversion assembly 300 is also included, which is connected to the discharge pipe 100 and is configured to control the exhaust gas flowing into the intake end 110 to be discharged from the exhaust end 120 through the first channel 130 or the second channel 140.

[0073] During a cold start, the splitter assembly 300 is in the second position, which closes the first channel 130 and opens the second channel 140, directing exhaust gas from the intake end 110 into the second channel 140. After being heated by the heater 200, the exhaust gas is discharged from the exhaust end 120. A cold start refers to the first start of the engine after a prolonged period of low temperature. As the engine gradually reaches its normal operating temperature, the exhaust gas temperature rises, and the splitter assembly 300 switches to the first position, opening the first channel 130 and closing the second channel 140. Exhaust gas enters the first channel 130 and is directly discharged from the exhaust end 120. When heating is not required, the exhaust gas flows out through the first channel 130, preventing the heater 200 from prolonged contact with the exhaust gas, thus protecting the heater 200.

[0074] In some embodiments, the first monitoring and control device includes a first monitoring device 400 and a power supply controller. The first monitoring device 400 is configured to monitor the operating information of the heater 200. The first monitoring device 400 may be a temperature sensor. The first monitoring device 400 and the power supply device 500 are respectively connected to the power supply controller, which is configured to control the power supply device 500 according to the operating information to adjust the voltage of the heater 200. The power supply device 500 is a power source. The heater 200 and the first monitoring device 400 are respectively connected to the power supply controller, which is configured to control the power supply device 500 according to the operating information of the heater 200 when the exhaust gas is discharged through the second channel 140, and adjust the voltage applied to the heater 200 by the power supply device 500.

[0075] Specifically, if the operating information indicates that heater 200 is overheating, the power supply controller controls the power supply equipment 500 to reduce the voltage applied to heater 200. If the operating information indicates that heater 200 is underheating, the power supply controller controls the power supply equipment 500 to increase the voltage applied to heater 200. If the operating status indicates that the temperature of heater 200 is rising rapidly or about to exceed the set temperature, the power supply controller controls the power supply equipment 500 to reduce the voltage applied to heater 200. The power supply controller flexibly adjusts the voltage applied to heater 200 by the power supply equipment 500 based on real-time monitoring of heater 200's operating information, ensuring that heater 200 operates at a suitable temperature. This not only optimizes energy efficiency and equipment lifespan but also improves system efficiency and reliability, supporting more environmentally friendly vehicle emissions.

[0076] In some embodiments, the power supply device 500 may be an external power source or an on-board power source. The external power source typically includes a battery that can provide a stable power supply, while the on-board power source utilizes the vehicle 20's electrical system to provide convenient power support for the device while it is in motion.

[0077] In some embodiments, the power supply controller may be placed inside the power supply device 500. The assembly of the power supply controller with the power supply device 500 facilitates overall installation and disassembly.

[0078] In some embodiments, please refer to Figure 5 and Figure 9 The heater 200 includes an insulating support 210 and a heating wire 220, the heating wire 220 being mounted on the insulating support 210.

[0079] In this embodiment, the insulating support 210 can be made of ceramic material, which has excellent insulation properties and high-temperature resistance. The heating wire 220 is typically made of a high-resistance alloy material, possessing excellent high-temperature resistance and a long service life, suitable for various types of electric heating equipment. The heating wire 220 is wound around a ceramic body; the ceramic has good thermal conductivity, ensuring uniform heat conduction. The insulating support 210 is installed within the second channel 140, effectively isolating the heating wire 220 from the discharge pipe 100, significantly improving the safety performance of the equipment.

[0080] In some embodiments, please refer to Figure 5 The insulating support 210 includes a connecting shaft 212 and a plurality of insulating discs 211. The plurality of insulating discs 211 are mounted on the connecting shaft 212. Along the axial direction of the connecting shaft 212, the plurality of insulating discs 211 are spaced apart. The heating wire 220 is wound sequentially on the insulating discs 211.

[0081] Specifically, please refer to Figure 5The insulating support 210 comprises a connecting shaft 212 and multiple insulating discs 211, which are uniformly mounted on the connecting shaft 212. The shape of the insulating discs 211 is the same as the cross-sectional shape of the second channel 140, such as being circular. These insulating discs 211 are spaced apart along the axial direction of the connecting shaft 212, ensuring structural stability and functionality. The connecting shaft 212 is made of metal, a material choice that not only gives it excellent structural strength but also significantly improves the overall strength and durability of the entire insulating support 210. To ensure uniform stress distribution on the connecting shaft 212 during operation, the axis of the connecting shaft 212 is concentric with the center of the second channel 140, optimizing stress distribution on the connecting shaft 212 and reducing stress concentration.

[0082] The heating wire 220 is wound on an insulating disc 211, which is made of ceramic material. The insulating disc 211 isolates the heating wire 220 from the connecting shaft 212, preventing direct contact between the heating wire 220 and the connecting shaft 212, thus improving the safety and service life of the heater 200. The overall structure of the insulating support 210 is compact, allowing for easy installation within the second channel 140 while saving space. This design balances ease of installation and maintenance, ensuring optimal performance within a limited space.

[0083] In some embodiments, please refer to Figure 5 and Figure 9 The heating wire 220 is a spiral heating wire 220. The spiral shape increases the heating area of ​​the heating wire 220, thereby improving the heating efficiency and uniformity of the heater 200. Furthermore, the spiral structure helps improve the mechanical strength and durability of the heating wire 220, allowing it to maintain stable performance during long-term use.

[0084] In some embodiments, please refer to Figure 9 The pitch of the spiral heating wire 220 is P, where 6mm ≤ P ≤ 8mm. The value of P can be 6mm, 7mm, 8mm, or other unlisted values. The pitch refers to the axial distance between corresponding points on the pitch diameter line of two adjacent threads of the spiral heating wire 220.

[0085] In this embodiment, the pitch of the spiral heating wire 220 is carefully designed to achieve optimal thermal efficiency and durability. The reasonable pitch design not only improves the heating efficiency of the heating wire 220 but also extends its service life, ensuring stable heat output during use.

[0086] In some embodiments, the heating wire 220 is wound into a helical structure along the axial direction of the connecting shaft 212. By winding the heating wire 220 into a helical structure along the axial direction of the connecting shaft 212, the surface area of ​​the heating wire 220 is maximized within a limited space, thereby improving thermal efficiency. Furthermore, the helical structure helps to distribute heat evenly, thus achieving a more efficient heating effect.

[0087] In some embodiments, please refer to Figure 9 The diameter of the spiral structure formed by the 220-winding heating wire is D, where 45mm ≤ D ≤ 65mm. The value of D can be 45mm, 47mm, 50mm, 52mm, 56mm, 60mm, 62mm, 65mm, or other unlisted values. The diameter of the spiral structure refers to the radial distance from the axis of its winding to the outermost layer of the helix.

[0088] In the embodiments of this application, the diameter design of the spiral structure of the heating wire 220 not only considers matching the diameter of the discharge pipe 100, but also takes into account the ease of winding the heating wire 220 on the insulating support 210. This ensures the stability and efficiency of the heating wire 220 during use, while also improving the overall performance of the system and the ease of installation.

[0089] In some embodiments, please refer to Figure 9 The spiral diameter of the spiral heating wire 220 is d, where 3mm ≤ d ≤ 5.5mm. The value of d can be 3mm, 4mm, 5mm, or other unlisted values. The spiral diameter of the spiral heating wire 220 refers to the radial distance from the axis around which it is wound to the outermost layer of the spiral.

[0090] In this embodiment, the total spiral diameter of the spiral heating wire 220 is reasonable, enabling the heating wire 220 to provide more efficient heating performance in a limited space, optimizing the heat output of the heating wire 220, improving energy efficiency, and meeting the needs of different applications.

[0091] In some embodiments, a second monitoring and control device is further included, connected to the diversion assembly 300, and configured to control the diversion assembly 300 to operate based on the monitored temperature of the exhaust gas, so that the exhaust gas flowing into the intake end 110 is discharged from the exhaust end 120 through the first channel 130 or the second channel 140. Automated control of the diversion assembly 300 facilitates adjustment and provides high control efficiency.

[0092] In some embodiments, a second monitoring and control device and a controller are provided. The second monitoring device is used to monitor the temperature information of the exhaust gas. The second monitoring device can be a temperature sensor. The second monitoring device and the diversion assembly 300 are respectively connected to the controller, which is configured to control the diversion assembly 300 to operate according to the temperature information of the exhaust gas, so that the exhaust gas flowing into the intake end 110 is discharged from the exhaust end 120 through the first channel 130 or the second channel 140.

[0093] Specifically, the controller has a temperature threshold. If the temperature detected by the second monitoring device is lower than the threshold, the controller activates the diversion component 300, causing the exhaust gas from the intake end 110 to be heated by the heater 200 in the second channel 140 before being discharged from the exhaust end 120. This ensures that the low-temperature exhaust gas is sufficiently heated to avoid affecting subsequent emission treatment due to excessively low temperatures. If the temperature detected by the second monitoring device is higher than the threshold, the controller activates the diversion component 300, causing the exhaust gas from the intake end 110 to pass through the first channel 130 and be directly discharged from the exhaust end 120. This ensures that the high-temperature exhaust gas can be discharged quickly and reduces unnecessary energy consumption.

[0094] In this embodiment, a second monitoring device monitors the temperature of the exhaust gas before it enters the inlet 110. The controller automatically controls the flow diversion component 300 based on the exhaust gas temperature, allowing gases of different temperatures to exit through corresponding channels. This design enables the selection of suitable channels under different temperature conditions, significantly improving the system's automation level, simplifying the operation process, and enhancing the efficiency and accuracy of gas processing.

[0095] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 The discharge pipe 100 also includes a first pipe body 150, a second pipe body 160, and a distributor 170. The distributor 170 includes an inlet end 110, a first open end 174, and a second open end 175. The distributor assembly 300 is partially installed inside the distributor 170. The first pipe body 150 has a first channel 130 and is connected to the first open end 174. The end of the first pipe body 150 facing away from the distributor 170 is the exhaust end 120. The second pipe body 160 has a second channel 140. One end of the second pipe body 160 is connected to the second open end 175, and the other end is connected to the pipe body of the first pipe body 150 near the exhaust end 120.

[0096] In this embodiment, the flow divider 170 of the discharge pipe 100 adopts a three-way structure design, which not only effectively connects the first pipe body 150 and the second pipe body 160, but also provides ample installation space for the flow divider assembly 300. This design makes the discharge pipe 100 more compact, reduces space occupation, and improves the convenience of installation and maintenance.

[0097] In some embodiments, please refer to Figure 6 The first open end 174 is inserted into the first tube body 150. The end of the first tube body 150 is inserted into the first open end 174, and a tight connection is ensured through an interference fit. This fitting method not only achieves an effective seal between the first tube body 150 and the distributor 170, but also enhances the stability of the connection. Because the connection structure between the distributor 170 and the first tube body 150 is simple, the installation process is quicker and more convenient, greatly improving assembly efficiency.

[0098] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 The second open end 175 is connected to the second pipe body 160 via a flange structure. The first open end 174 is provided with a flange, and the end of the second pipe body 160 is provided with a flange. The flange of the first open end 174 and the flange of the end of the second pipe body 160 are connected by bolts.

[0099] In this embodiment, the connection between the second open end 175 and the second pipe body 160 employs a flange structure to ensure stability and sealing. The two flanges are tightly connected by bolts, forming a reliable mating interface. This design not only effectively prevents gas leakage but also facilitates installation and disassembly, making it suitable for applications requiring frequent maintenance.

[0100] In some embodiments, please refer to Figure 2 and Figure 6 The first pipe body 150 has a bend 180 connected to it near the exhaust end 120. A flange is fitted at the end of the bend 180 away from the first pipe body 150, and a flange is also fitted at the end of the second pipe body 160 away from the fluid distributor 170. The bend 180 and the second pipe body 160 are connected by a flange structure. This design not only simplifies the installation and disassembly of the second pipe body 160 and the bend 180, but also facilitates the rapid overall installation and removal of the second pipe body 160. Furthermore, this structure provides convenient maintenance conditions for the heater 200 inside the second pipe body 160, improving the efficiency of equipment maintenance and repair.

[0101] In some embodiments, the angle formed by the first pipe body 150 and the bend 180 is θ, where 45° ≤ θ < 90°. The angle formed by the first pipe body 150 and the bend 180 is the angle formed by the line connecting the midpoints of the two ends of the bend 180 and the axis of the first pipe body 150. The value of θ can be 45°, 50°, 60°, 65°, 70°, 85°, or other unlisted values.

[0102] In the embodiments of this application, if the angle between the first pipe body 150 and the bend 180 is small, it will lead to an increase in the size of the bend 180, thereby increasing material costs. Furthermore, a small angle may reduce fluid flow efficiency. Conversely, if the angle is too large, it may cause exhaust gas to flow back from the first pipe body 150 to the second pipe body 160, resulting in exhaust gas backflow. This backflow not only affects the normal operation of the system but may also lead to reduced equipment efficiency and even safety hazards. Therefore, in designing the angle between the first pipe body 150 and the bend 180, the embodiments of this application comprehensively consider material costs, fluid dynamics performance, and system safety to achieve the best design effect.

[0103] In some embodiments, please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 The flow divider 170 includes a main body 171, a transition section 172, and a hemispherical section 173. The main body 171 has a cylindrical structure and connects the transition section 172 and the hemispherical section 173. The diameters at both ends of the main body 171 are the same as the diameter of the end of the transition section 172 away from the air inlet 110 and the diameter of the end of the hemispherical section 173. The air inlet 110 is located at the end of the transition section 172 away from the main body 171, and the diameter of the transition section 172 gradually decreases along the direction away from the main body 171. The hemispherical section 173 has a first opening end 174 and a second opening end 175 on the side away from the main body 171. The flow divider assembly 300 is partially located inside the hemispherical section 173 to block the openings inside the hemispherical section 173 corresponding to the first opening end 174 and the second opening end 175.

[0104] In the embodiments of this application, after the exhaust gas enters the gradient section 172 through the inlet end 110, it flows through the main body section 171 and the hemispherical section 173, and finally exits from the first opening end 174 or the second opening end 175. During the exhaust gas flow process, the design of the gradient section 172 enables the exhaust gas to effectively diffuse after entering the distributor 170, reducing concentration and lowering flow resistance. In addition, the hemispherical section 173 provides ample space, allowing the distributor assembly 300 to rotate freely and avoiding jamming, thereby significantly improving the reliability of the distributor assembly 300 and the stability of the entire system.

[0105] In some embodiments, please refer to Figure 2 and Figure 3 The diversion assembly 300 includes a drive mechanism 310 and a plugging member 320. The drive mechanism 310 is connected to the plugging member 320, which is located inside the diversion fluid 170. The drive mechanism 310 is installed outside the diversion fluid 170. The drive mechanism 310 is used to drive the plugging member 320 to switch between a first position and a second position.

[0106] Specifically, in the first position, exhaust gas flowing into the intake end 110 is discharged from the exhaust end 120 through the first channel 130. In the first position, the sealing member 320 seals the opening corresponding to the second opening end 175. In the second position, exhaust gas flowing into the intake end 110 is discharged from the exhaust end 120 through the second channel 140. In the second position, the sealing member 320 seals the opening corresponding to the first opening end 174.

[0107] In this embodiment, the drive mechanism 310 is disposed outside the distributor 170. This design increases the installation space of the drive mechanism 310 and avoids occupying scarce internal space resources of the distributor 170, thereby providing greater flexibility and convenience for the product's structural design. Through precise control, the drive mechanism 310 realizes the switching of the sealing component 320 between a first position and a second position, thereby realizing the switching between the first channel 130 and the second channel 140. The design of the sealing component 320 maintains simplicity and efficiency, reducing the number of parts and thus effectively utilizing the internal space of the distributor 170. This not only simplifies the internal structure but also promotes the miniaturization design of the distributor 170.

[0108] In some embodiments, please refer to Figure 3 The sealing element 320 has an arc-shaped sealing surface 321, which has the same curvature as the hemispherical portion 173, so as to seal the openings in the hemispherical portion 173 that correspond to the first opening end 174 and the second opening end 175.

[0109] Specifically, please refer to Figure 3 and Figure 6 The sealing element 320 is designed with an arc-shaped sealing surface, the curvature of which is consistent with the curvature of the hemispherical portion 173, thereby effectively sealing the openings inside the hemispherical portion 173 corresponding to the first opening end 174 and the second opening end 175. Specifically, the sealing element 320 has an arc-shaped structure. The output end of the drive mechanism 310 is connected to one end of the sealing element 320 via the distributor 170, and the other end is connected to the bottom of the distributor 170. The bottom of the distributor 170 is provided with a platform 176, and the lower end of the sealing element 320 is equipped with a screw, which fixes the sealing element 320 to the platform 176 of the distributor 170. In addition, the sealing element 320 and the screw are connected by rotation, allowing the sealing element 320 to operate flexibly. The curvature of the arc surface around the openings inside the hemispherical portion 173 corresponding to the first opening end 174 and the second opening end 175 is exactly the same as the arc curvature of the sealing element 320, thereby ensuring the effectiveness of the seal.

[0110] In the embodiments of this application, the arc-shaped sealing surface 321 of the sealing member 320 has the same curvature as the hemispherical portion 173. This design ensures that the sealing portion can completely seal the openings corresponding to the first opening end 174 and the second opening end 175, significantly improving the sealing performance. The arc-shaped structure design of the sealing member 320 not only effectively saves space but also allows rotation along the inner surface of the hemispherical portion 173, avoiding jamming and potential damage, and significantly improving the reliability and durability of the sealing member 320.

[0111] In some embodiments, please refer to Figure 3 The drive mechanism 310 includes a hydraulic control component 311, a hydraulic pipe 312, a hydraulic converter 313, and a transmission component 314. The hydraulic pipe 312 connects the hydraulic control component 311 and the hydraulic converter 313. The hydraulic control component 311 can be a solenoid valve. The hydraulic control component 311 is connected to the hydraulic converter 313 via the hydraulic pipe 312, thus keeping the hydraulic control component 311 away from the discharge pipe 100. This reduces the impact of heat emitted from the exhaust gas in the discharge pipe 100 on the hydraulic control component 311, improving its reliability and service life. The transmission component 314 connects the hydraulic converter 313 and the transmission component 314, with its end passing through the distributor 170 and connecting to the sealing component 320. The hydraulic control component 311 controls the flow of liquid from the hydraulic pipe 312 into or out of the hydraulic converter 313, thereby driving the transmission component 314 to rotate the sealing component 320.

[0112] The hydraulic control component 311 can precisely regulate the fluid flow within the hydraulic pipe 312, ensuring accurate delivery of the fluid to the hydraulic conversion component 313. By utilizing the changes in fluid flow, the hydraulic conversion component 313 converts the fluid's kinetic energy into mechanical energy, thereby driving the transmission component 314. Once the transmission component 314 receives sufficient driving force, it rotates the connected sealing component 320, thus switching between the first channel 130 and the second channel 140. This improves the system's operational efficiency and increases the reliability and durability of the drive mechanism 310, making it suitable for various complex operating conditions.

[0113] In some embodiments, please refer to Figure 3 and Figure 4The hydraulic conversion component 313 includes a sealed housing 3131 and a rotor 3132. The rotor 3132 is installed inside the sealed housing 3131 and is connected to the transmission component 314. The sealed housing 3131 is connected to a hydraulic pipe 312, which is used to supply or discharge liquid into the sealed housing 3131 to drive the rotor 3132 to rotate the transmission component 314. The rotor 3132 has blades distributed circumferentially. The hydraulic pipe 312 supplies liquid to the sealed housing 3131, which acts on the blades. The blades convert the kinetic energy of the liquid into mechanical energy, which drives the rotor 3132 to rotate. The rotor 3132 then drives the transmission component 314 to rotate.

[0114] In this embodiment, the hydraulic converter 313 can effectively convert the pressure of the liquid into mechanical energy, realizing energy transfer and conversion, and is suitable for various mechanical and industrial applications. The sealing design of the entire system ensures the high efficiency and safety of liquid transmission, prevents liquid leakage, and improves the efficiency of energy conversion.

[0115] In some embodiments, please refer to Figure 2 and Figure 3 The transmission component 314 includes a first gear 3141 and a second gear 3142 that mesh with each other. The axis of the first gear 3141 intersects the axis of the second gear 3142. The second gear 3142 is closer to the sealing component 320 than the first gear 3141. The first gear 3141 is connected to the hydraulic conversion component 313, and the second gear 3142 is connected to the sealing component 320.

[0116] In the embodiments of this application, the transmission component 314 adopts a vertical gear set structure to realize the conversion of input and output directions, making the arrangement of the transmission component 314, the sealing component 320 and the hydraulic conversion component 313 more convenient and enabling optimal configuration within a limited space.

[0117] In some embodiments, please refer to Figure 2 and Figure 3 The hydraulic pipe 312 includes a first inlet pipe 3121 and a second inlet pipe 3122. The first inlet pipe 3121 and the second inlet pipe 3122 are connected between the hydraulic control component 311 and the hydraulic conversion component 313. One of the first inlet pipe 3121 and the second inlet pipe 3122 serves as an inlet pipe, and the other as an outlet pipe. The inlet pipe's function is to deliver liquid through the hydraulic control component 311 to the hydraulic conversion component 313. The outlet pipe is responsible for returning the liquid in the hydraulic conversion component 313 to the hydraulic pump or the vehicle's hydraulic system, completing the liquid circulation.

[0118] In this embodiment, when the first infusion tube 3121 is used as the inlet tube and the second infusion tube 3122 is used as the outlet tube, the hydraulic control component 311 drives the transmission component 314 to rotate in the first direction; when the first infusion tube 3121 is used as the outlet tube and the second infusion tube 3122 is used as the inlet tube, the hydraulic control component 311 drives the transmission component 314 to rotate in the opposite direction to the first direction, thereby realizing the forward and reverse rotation of the sealing component 320.

[0119] In some embodiments, a hydraulic pump or automotive hydraulic system is also included, and the hydraulic control unit 311 is connected to the hydraulic pump or automotive hydraulic system.

[0120] In this embodiment, the hydraulic control component 311 is mainly used to regulate the fluid flow rate in the hydraulic pump or automotive hydraulic system, as well as other related parameters. Utilizing the existing automotive hydraulic system not only improves the system's functionality and reliability but also significantly saves resources and reduces costs.

[0121] In some embodiments, please refer to Figure 2 and Figure 3 The diversion assembly 300 also includes a cooling mechanism 330 located next to the hydraulic pipe 312 for cooling the liquid inside the hydraulic pipe 312. The cooling mechanism 330 can be a fan, which removes heat from the liquid inside the hydraulic pipe 312 by air cooling, reducing the impact of heat on the hydraulic control component 311 and improving the reliability of the hydraulic control component 311.

[0122] In other embodiments, the hydraulic pipe 312 is connected to the air outside the vehicle body, so that the airflow generated during the movement of the vehicle 20 convects with the hydraulic pipe 312 to cool the liquid inside the hydraulic pipe 312.

[0123] In some embodiments, please refer to Figure 2 and Figure 11 The power supply device 500 is cleverly positioned outside the discharge pipe 100 and electrically connected to the heater 200 via a wire 510. Specifically, the positive terminal of the power supply device 500 is connected to the positive terminal of the heater 200 via the wire 510, while the negative terminal of the power supply device 500 is connected to the negative terminal of the heater 200 via the wire 510. For ease of installation and maintenance, a terminal block 420 is designed at the end of the wire 510 connected to the heater 200, ensuring ease of operation and reliability.

[0124] In the embodiments of this application, by using a wire 510 to connect the power supply device 500 to the integrated terminal 230 on the heater 200, the power supply device 500 can be kept away from high-temperature areas, thereby effectively avoiding the potential impact of high temperatures on the power supply device 500. This design not only improves the operational reliability of the power supply device 500 but also extends its service life. Furthermore, the separate design of the power supply device 500 and the heater 200 facilitates flexible adjustment and adaptation in different environments.

[0125] In some embodiments, please refer to Figure 2 and Figure 10 The first monitoring device 400 is installed outside the discharge pipe 100, connected to the heater 200 via a signal line 410, and connected to the power supply equipment 500 via a wire 510. One end of the signal line 410 connected to the heater 200 has a terminal block 420, which connects to the integrated terminal block 230 on the heater 200 for easy operation. The main function of this monitoring device is to monitor the current and voltage parameters of the heater 200 in real time. Based on the thermal resistance characteristic curve of the heating wire 220, the operating information of the heater 200 can be accurately obtained by calculating the relationship between the voltage and current of the heater 200. The operating information includes whether the heater 200 is overheating, underheating, heating too quickly, or approaching its limit temperature. After obtaining the operating information, the first monitoring device 400 transmits it to the power supply controller via the wire 510. The power supply controller then controls the power supply equipment 500 to adjust the voltage of the heater 200 according to its operating status. This protects the heater 200 and extends its service life.

[0126] According to a second aspect of this disclosure, a vehicle 20 is provided, which includes the exhaust gas treatment system 10 described above, and the vehicle 20 has all the beneficial effects of the exhaust gas treatment system 10 described above, which will not be repeated here.

[0127] The vehicle 20 may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.

[0128] This disclosure exemplarily describes the operation of the exhaust gas treatment system 10:

[0129] During the cold start phase of vehicle 20, the splitter assembly 300 moves to the second position, at which point the intake end 110 is connected to the second channel 140, and the first channel 130 is closed. The heater 200 is activated to heat the exhaust gas in the second channel 140, and the heated exhaust gas is discharged through the exhaust end 120. During the operation of the heater 200, the first monitoring device 400 monitors the operation of the heater 200 in real time and transmits the collected information to the power supply controller. The power supply controller controls the power supply equipment 500 based on this information and adjusts the voltage of the heater 200.

[0130] If the monitored information indicates that heater 200 is overheating, heating up too quickly, or approaching its limit temperature, power supply device 500 will reduce the voltage of heater 200. If heater 200 is not warm enough, power supply device 500 will increase its voltage.

[0131] When the engine starts, the exhaust gas temperature reaches a level where it can be directly discharged. The splitter assembly 300 switches to the first position. At this time, the intake end 110 is connected to the first channel 130, the second channel 140 is closed, and the gas is discharged directly through the first channel 130.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0133] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0134] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0135] The above are merely preferred embodiments of this application and are not intended to limit this application in any way.
