[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figures 1 to 5 As shown, the automobile exhaust emission detection alarm device of this utility model includes a detection alarm device body 1, one end of the detection alarm device body 1 is connected to an intake pipe 2, the other end of the detection alarm device body 1 is connected to an exhaust pipe 3, an alarm 4 is fixed on one side of the top of the detection alarm device body 1, a first diverter seat 5 is distributed on the inner side of one end of the detection alarm device body 1, and a detection sensor 6 is distributed above the first diverter seat 5.

[0026] A drive motor 7 is distributed on one side of the exhaust pipe 3, and an eccentric wheel 8 is connected to the output end of the drive motor 7. A movable plate 9 is distributed on one side of the eccentric wheel 8, and a linkage rod 10 is fixedly connected to one side of the top of the movable plate 9. A filter plate 11 is fixedly connected to the other end of the linkage rod 10. A reset spring 12 is sleeved on the outer surface of the linkage rod 10. A flow guide seat 13 is distributed on the other side of the filter plate 11, and an adsorption plate 14 is fixedly connected to the inner side of the flow guide seat 13. A second flow divider seat 15 is distributed on the side of the adsorption plate 14 away from the filter plate 11.

[0027] During operation, vehicle exhaust gas is input into the inner side of the detection and alarm device body 1 through the intake pipe 2. The exhaust gas then undergoes diversion processing via the first diverter 5. The diverted exhaust gas then passes through the detection sensor 6, which detects and processes the exhaust gas. If excessive levels of harmful substances are detected, the alarm 4 is activated via the control terminal, triggering an alarm. The detected exhaust gas then passes through the heat exchanger 16 and is input into the inner side of the other end of the detection and alarm device body 1. There, it passes through the second diverter 15, which further diverts the exhaust gas. Multiple guide channels evenly spaced on the inclined surface of the second diverter 15 further divert the exhaust gas. The diverted exhaust gas then flows along the inclined surface of the guide seat 13. The airflow is facilitated by multiple arc-shaped grooves evenly spaced on the inclined surface of the guide seat 13, which cause the exhaust gas to flow back as it passes through. Under the action of air pressure, particulate matter is trapped in the arc-shaped grooves. Then, the adsorption plate 14 is used to further adsorb the exhaust gas. At the same time, the drive motor 7 works, causing the eccentric wheel 8 connected to its output end to rotate. The rotation of the eccentric wheel 8 pushes the movable plate 9. At this time, the movable plate 9 drives the linkage rod 10 to move on one side of the detection alarm device body 1. When the linkage rod 10 moves, it pulls the filter plate 11 and squeezes the return spring 12 to deform. The reverse force generated by the deformation of the return spring 12 can reset the filter plate 11 when the eccentric wheel 8 separates from the movable plate 9. This reciprocating motion of the filter plate 11 can achieve lateral reciprocating motion, thereby better filtering and purifying the exhaust gas.

[0028] Furthermore, a heat exchanger 16 is provided on the inner side of the middle section of the main body 1 of the detection alarm device, and a heat recovery pipe 17 is fixedly connected to the top of the heat exchanger 16, an air supply pipe 18 is fixedly connected to one side of the bottom of the heat exchanger 16, and a ventilation pipe 19 is fixedly connected to the side wall of the heat exchanger 16.

[0029] During operation, when the detected vehicle exhaust gas enters the inside of the heat exchanger 16 through the ventilation pipe 19, the heat energy in the vehicle exhaust gas can be stripped off by the heat exchanger 16. The stripped heat energy then enters the inside of the heat recovery pipe 17 and is transported through the heat recovery pipe 17 for subsequent heat energy recovery and reuse. The air supply pipe 18 facilitates the subsequent input of air into the inside of the heat exchanger 16.

[0030] Furthermore, the detection sensors 6 are equidistantly distributed at both ends of the first diversion seat 5, and the first diversion seat 5 is fixed to the inner side wall of the detection alarm device body 1;

[0031] During operation, vehicle exhaust gas is input into the inner side of the detection alarm device body 1 and is diverted through the first diverter seat 5. The diverted vehicle exhaust gas then passes through the detection sensors 6, and multiple detection sensors 6 are used to detect and process the vehicle exhaust gas.

[0032] Furthermore, the movable plate 9 is slidably connected to the detection alarm device body 1 via the linkage rod 10, and the movable plate 9 is symmetrically distributed along the vertical center line of the detection alarm device body 1.

[0033] When the movable plate 9 moves, the linkage rod 10 will also move, and the movement of the linkage rod 10 will drive the filter plate 11 to move synchronously, so that the filter plate 11 can be better used to filter and purify the vehicle exhaust.

[0034] Furthermore, the two ends of the return spring 12 are respectively fixedly connected to the outer wall of the detection alarm device body 1 and the side of the movable plate 9 near the detection alarm device body 1;

[0035] During operation, when the movable plate 9 moves under the action of the eccentric wheel 8, the movable plate 9 will pull the linkage rod 10, and then the movement of the linkage rod 10 will drive the return spring 12 to deform and generate a reverse force, which facilitates the subsequent rotation of the eccentric wheel 8 to realize the reciprocating motion of the movable plate 9.

[0036] Furthermore, the flow guide seat 13 is provided with an inclined surface on the side near the second flow divider seat 15, and multiple arc-shaped grooves are equally spaced on the inclined surface.

[0037] During operation, since the inclined surface of the guide seat 13 is provided with multiple arc-shaped grooves at equal intervals, when the vehicle exhaust flows along the inclined surface of the guide seat 13, the multiple arc-shaped grooves can be used to facilitate the effective removal of impurities in the vehicle exhaust.

[0038] Furthermore, the heat recovery pipe 17 penetrates the top of the detection alarm device body 1, and the air supply pipe 18 penetrates the bottom of the detection alarm device body 1.

[0039] During operation, the heat recovery pipe 17 and the air supply pipe 18 are connected to the external structure to facilitate the subsequent recovery and reuse of heat energy and the input of air into the inside of the heat exchanger 16.

[0040] Specific working principle:

[0041] Vehicle exhaust gas is input into the inner side of the detection and alarm device body 1 through the intake pipe 2. The exhaust gas then undergoes diversion processing via the first diversion seat 5. The diverted exhaust gas then passes through the detection sensor 6, which detects and processes the exhaust gas. If harmful substances in the exhaust gas exceed the standard, the alarm 4 is activated and an alarm is sounded via the control terminal. The detected exhaust gas then enters the heat exchanger 16, where heat energy is stripped from the exhaust gas. This stripped heat energy then enters the inner side of the heat recovery pipe 17 and is transported through it for subsequent heat energy recovery and reuse. An air supply pipe 18 facilitates the subsequent input of air into the inner side of the heat exchanger 16. The exhaust gas then passes through the second diversion seat 15, which further diverts the exhaust gas. Multiple equally spaced sections on the inclined surface of the second diversion seat 15 are used for this purpose. The guide channel further diverts the vehicle exhaust gas. After diversion, the exhaust gas flows along the inclined surface of the guide seat 13. Multiple arc-shaped grooves evenly spaced on the inclined surface of the guide seat 13 cause the exhaust gas to flow back. Under the action of air pressure, particulate matter is trapped in the arc-shaped grooves. Then, the adsorption plate 14 further adsorbs the exhaust gas. At the same time, the drive motor 7 operates, causing the eccentric wheel 8 connected to its output end to rotate. The rotation of the eccentric wheel 8 pushes the movable plate 9. At this time, the movable plate 9 drives the linkage rod 10 to move on one side of the detection alarm device body 1. When the linkage rod 10 moves, it pulls the filter plate 11 and causes the return spring 12 to deform. Then, the reverse force generated by the deformation of the return spring 12 can reset the filter plate 11 when the eccentric wheel 8 separates from the movable plate 9. This reciprocating motion of the filter plate 11 can achieve better filtration and purification of the vehicle exhaust gas.
