[0002] In automotive exhaust systems, especially catalytic converter systems containing GPF, a variety of sensors are typically required, such as oxygen sensors, differential pressure sensors, and temperature sensors. These sensors are numerous and their placement is complex. Under EGR (exhaust gas recirculation) conditions, the sensors occupy a large space, making their placement difficult and costly. The placement of sensors is often limited by space and design requirements, leading to difficulties in placement or increased costs to meet the requirements. Summary of the Invention

Detailed Implementation

[0011] Reference Figures 1-4 The highly adaptable sensor structure is characterized by comprising a catalyst 1 and an intake cone end 2 connected to the center of the left side surface of the catalyst 1. A differential pressure pipe 3 is inserted at the outer edge of the left side surface of the intake cone end 2. An exhaust cone end 4 is connected to the center of the right side surface of the catalyst 1. An exhaust pipe 5 is connected to the center of the right side surface of the exhaust cone end 4. A protective jacket 6 is welded to the outer edge of the right side surface of the exhaust cone end 4. A sensor probe 7 is inserted at the center of the outer surface of the protective jacket 6.

[0012] During use, because the differential pressure pipe 3 is lower than the height of the intake cone end 2 when it is connected to the intake cone end 2, the pressure inside the catalyst 1 is too high and backflow occurs. When the protective cover 6 is on, the angle between the protective cover 6 and the exhaust cone end 4 increases, so that the workers will not touch the exhaust cone end 4 and the protective cover 6 during welding. Then, the sensor probe 7 is inserted into the protective cover 6. Finally, the car exhaust gas enters the catalyst 1 and is discharged through the exhaust pipe 5.

[0013] Furthermore, the intake cone end 2 includes an end cover 2-1, a flange 2-2, a sleeve 2-3, and a gasket 2-4. The flange 2-2 is connected to the center of the left side surface of the end cover 2-1, the sleeve 2-3 is connected to the outer edge of the left side surface of the end cover 2-1, and the gasket 2-4 is connected to the four edges of the left side surface of the flange 2-2. The end cover 2-1 is conical in shape, and the sleeve 2-3 forms a downward angle with the differential pressure pipe 3. The end cover 2-1 is connected to the left side of the catalyst 1.

[0014] During use, due to the upward angle of the sleeve 2-3 and the flange 2-2, when the differential pressure pipe 2 is inserted into the sleeve 2-3, the differential pressure pipe 3 is at a downward angle. During use, water will not accumulate or ice blockage will occur at the inflection point of the differential pressure pipe 3. The flange 2-2 is connected to the car air pipe and the rubber gasket 2-4 is sealed. The exhaust gas is injected into the catalyst 1 through the end cap 2-1.

[0015] Furthermore, the exhaust cone end 4 includes a cone cover 4-1, a locking block 4-2, a welding ring 4-3, and a welding end 4-4. The locking block 4-2 is connected to the lower edge of the right side surface of the cone cover 4-1, the welding ring 4-3 is connected to the center of the right side surface of the cone cover 4-1, and the welding end 4-4 is connected to the upper edge of the right side surface of the cone cover 4-1. The locking block 4-2 is concave in shape, the welding ring 4-3 is welded to the exhaust pipe 5, the welding end 4-4 is at a forward and upward angle, the cone cover 4-1 is conical in shape, and the differential pressure pipe 3 is inserted into the locking block 4-2.

[0016] In use, the vehicle exhaust gas is injected into the exhaust pipe 5 through the cone cover 4-1 and the welding ring 4-3 and discharged, while the differential pressure pipe 3 is inserted into the clamp block 4-2 for fixation.

[0017] Furthermore, the protective outer casing 6 includes a protective tube 6-1, an insert 6-2, a rubber ring 6-3, and a nut 6-4. The insert 6-3 is connected to the center of the lower surface of the protective tube 6-1, and the rubber ring 6-3 is connected to the four edges of the upper surface of the protective tube 6-1. The nut 6-4 is inserted into the center of the upper surface of the protective tube 6-1. The lower surface of the protective tube 6-1 is sloping. The insert 6-2 is inserted into the welding end 4-4. The nut 6-4 is T-shaped and is tightened onto the upper surface of the protective tube 6-1.

[0018] In use, insert the insertion rod 6-2 into the welding end 4-4 while the protective tube 6-1 is secured to the outer surface of the welding end 4-4. Then, rotate the protective tube 6-1. Since the lower surface of the protective tube 6-1 is sloping, the distance between the protective tube 6-1 and the cone cap 4-1 can be adjusted while rotating the protective tube 6-1. After adjustment, weld the protective tube 6-1 to the welding end 4-4. During welding, the welding torch will not touch the cone cap 4-1 or the protective tube 6-1. Finally, insert the sensor probe 7 into the protective tube 6-1 and tighten it with the nut 6-4. Seal it with the rubber ring 6-3 before use.

[0019] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
