[0080] In the prior art, the risk of icing of the differential pressure sensor is usually solved by heating the air intake pipe, heating the start-up control unit, or monitoring the volume flow and pressure difference changes in the differential pressure sensor. However, the solutions in the prior art fail to effectively prevent water vapor from entering the differential pressure sensor, and condensation water may accumulate, causing the performance of the differential pressure sensor to deteriorate or cause failure.

[0081] In order to solve the above problems, the core concept of the present application is to provide an air intake pipe assembly including a first air intake pipe, a second air intake pipe and a buffer bottle; the first air intake pipe is connected to the particle collector for transmitting the high-temperature gas flowing out of the particle collector; the second air intake pipe is connected to the air intake port of the differential pressure sensor; the buffer bottle includes a accommodating cavity, the bottom end of the buffer bottle is connected to the first air intake pipe, the top end of the buffer bottle is connected to the second air intake pipe, and the orthographic projection of the end of the first air intake pipe located in the buffer bottle in the first direction is staggered with the orthographic projection of the end of the second air intake pipe located in the buffer bottle in the first direction, wherein the first direction is from the top of the buffer bottle to the bottom of the buffer bottle; wherein the accommodating cavity is used to condense and store the high-temperature gas flowing out of the first air intake pipe to prevent the high-temperature gas from entering the differential pressure sensor after condensation, thereby improving the stability and reliability of the differential pressure sensor.

[0086] Alternatively, in a cold or humid environment, moisture in the air may enter the particle trap. When the temperature of the particle trap is increased, the moisture in the air is converted into water vapor and transmitted through the first air intake pipe 101 .

[0087] The second air intake pipe 102 is used to communicate with the air intake port of the differential pressure sensor 201 .

[0088] Optionally, a heating element 104 is provided outside the second air extraction pipe 102;

[0089] The heating element 104 is used to be connected to a heating device, and the high-temperature gas flowing through the second gas extraction pipe 102 is heated by the heating device.

[0097] In this embodiment, the first air intake pipe 101 and the second air intake pipe 102 are staggered with each other, which can prevent the refluxed condensed water from dripping into the first air intake pipe 101 and causing the condensed water to flow back to the particulate trap.

[0098] The accommodating chamber 1031 is used to condense and store the high-temperature gas flowing out of the first gas extraction pipe to prevent the high-temperature gas from entering the differential pressure sensor 201 after condensation.

[0099] In this embodiment, when the water vapor input from the first air intake pipe 101 and the second air intake pipe 102 condenses into condensed water, it is stored in the accommodating cavity 1031 , which can effectively prevent the condensed water from entering the differential pressure sensor 201 and affecting the performance of the differential pressure sensor 201 .

[0100] Optionally, the second air extraction pipe 102 includes a first section and a second section, and the first section and the second section are connected;

[0110] The control component 107 is used to adjust the state of the accommodating chamber 1031 .

[0111] In this embodiment, the detection component 106 includes a liquid level sensor and a temperature sensor; the control component 107 includes a heater and an alarm control component; and both the detection component 106 and the control component 107 are connected to a control device.

[0112] For example, the exhaust switch 1051 on the exhaust pipe 105 can be a solenoid valve, which is connected to the control component 107; the liquid level sensor is connected to the control component 107, and when the liquid level sensor detects that the water level in the buffer bottle 103 reaches a preset water level, the alarm control component in the control component 107 generates an alarm and controls the solenoid valve switch to allow the exhaust pipe 105 to remove the condensed water in the buffer bottle 103.

[0113] The heater in the control component 107 is arranged at the bottom of the buffer bottle 103, and the control component 107 is connected to the temperature sensor. When the temperature sensor detects that the temperature in the buffer bottle 103 is at a preset temperature threshold, the heater in the control component 107 performs a heating operation to prevent the condensed water in the buffer bottle 103 from freezing due to the low temperature.

[0114] The air intake pipe assembly provided in the present application is used to transmit the high-temperature gas flowing out of the particle collector through the first air intake pipe 101 and the second air intake pipe 102, respectively, and to transmit the water vapor of the pressure difference sensor 201 to the accommodating cavity 1031 in the buffer bottle 103; and the bottom end of the buffer bottle 103 is connected to the first air intake pipe 101, and the top end of the buffer bottle 103 is connected to the second air intake pipe 102, and the orthographic projection of the end of the first air intake pipe 101 located in the buffer bottle 103 in the first direction is aligned with the second air intake pipe 102 located in the buffer bottle 103. The orthographic projections of the end portions in the first direction are staggered with each other, wherein the first direction is the direction from the top of the buffer bottle 103 to the bottom of the buffer bottle 103; wherein the accommodating cavity 1031 is used to condense and store the high-temperature gas flowing out of the first air intake pipe to prevent the high-temperature gas from condensing and entering the differential pressure sensor 201; it effectively prevents water vapor from the first air intake pipe 101 from entering the differential pressure sensor 201 via the second air intake pipe 102, and also prevents water vapor from condensing into condensed water and entering the particulate collector, thereby improving the reliability and stability of the air intake pipe assembly.

[0116] The first flow guide component 301 is arranged in the accommodating cavity 1031, and the orthographic projection of the center of the first flow guide component 301 in the first direction is arranged opposite to the orthographic projection of the end of the first air intake pipe 101 located in the buffer bottle 103 in the first direction. The first flow guide component 301 is used to condense the high-temperature gas flowing out of the first air intake pipe 101 and guide it to the bottom of the buffer bottle so as to be discharged through the drain pipe 107.

[0119] The vertical head 3015 is arranged at the lower end of the guiding hose 3014 to prevent the liquid from overflowing when the buffer bottle 103 is tilted.

[0120] In this embodiment, if Figure 3 As shown, the first guide assembly 301 further includes a connecting plate 3013 , which connects the second end of the first guide plate 3011 and the second end of the second guide plate 3012 , and the connecting plate 3013 is provided with a plurality of drainage ports 3016 .

[0121] The guide hose 3014 is connected to the drain port 3016 on the connecting plate 3013, and is used to discharge the condensed water collected by the first guide component 301 to the bottom of the accommodating chamber 1031; and the first guide component 301 and the bottom of the accommodating chamber 1031 form a relatively closed space, which effectively prevents the condensed water from flowing back and entering the differential pressure sensor 201;
