[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] The specific embodiment of the vehicle environmental protection identification device provided by the utility model is as follows:

[0026] See also Figure 1-3 The vehicle environmental protection identification device includes an air duct 1 bent in the middle. In this embodiment, the bending angle of the middle part of the air duct 1 is ninety degrees; one end of the air duct 1 is an air intake end and the other end is an exhaust end. The air intake end of the air duct 1 is extended into the exhaust pipe of the vehicle, so that the exhaust gas of the vehicle enters from the air intake end of the air duct 1, passes through the air duct 1, and is discharged from the exhaust end.

[0027] A fixed ring 4, a first movable ring 5 and a second movable ring 6 are provided on the outer side of the air inlet end of the air guide tube 1. The first movable ring 5 and the second movable ring 6 are respectively placed on both sides of the fixed ring 4 and slide along the air guide tube 1; a plurality of connecting rods 7 are connected between the first movable ring 5 and the second movable ring 6, and the connecting rods 7 slide through the fixed ring 4, and the fixed ring 4 is provided with through holes for the connecting rods 7 to pass through; the first movable ring 5 is located on the side of the fixed ring 4 facing the pipe opening of the air inlet end of the air guide tube 1, and a rubber sealing cover 9 and a V-shaped elastic sheet 8 are connected between the first movable ring 5 and the fixed ring 4. The V-shaped elastic sheet 8 is an elastic steel sheet, and a plurality of them are arranged around the circumference, and the rubber sealing cover 9 is wrapped around the outside of the V-shaped elastic sheet 8; a handle 10 is connected to one side of the second movable ring 6.

[0028] A right-angle reinforcing rod 11 is connected to one side of the middle of the airway tube 1, and a rectangular frame is formed between the right-angle reinforcing rod 11 and the middle of the airway tube 1. A slide groove 12 is provided on the right-angle reinforcing rod 11 to be slidably connected to the end of the handle 10. The slide groove 12 provides a guide for the movement of the handle 10, so that the handle 10 can move back and forth stably. When in use, the middle of the airway tube 1 is held, and the driving handle 10 can be held by fingers, thereby moving the first movable ring 5 and the second movable ring 6.

[0029] The air inlet end of the air duct 1 is extended into the inner side of the vehicle exhaust pipe, and the second movable ring 6 is moved along the air duct 1 by moving the handle 10, thereby driving the connecting rod 7 and the first movable ring 5 to move. The first movable ring 5 moves toward the fixed ring 4 and compresses the V-shaped elastic sheet 8, so that the angle of the V-shaped elastic sheet 8 becomes smaller, thereby increasing the outer diameter of the rubber sealing cover 9; the rubber sealing cover 9 is tightly attached to the inner side of the vehicle exhaust pipe, so that the air duct 1 and the vehicle exhaust pipe are sealed, so that all the vehicle exhaust gas passes through the air duct 1.

[0030] When the handle 10 is released and no force is applied to the handle 10, the V-shaped elastic sheet 8 automatically increases in angle and resets under the elastic force, the first movable ring 5 moves away from the fixed ring 4, and the outer diameter of the rubber sealing cover 9 decreases, so that the air guide pipe 1 can be pulled out of the vehicle exhaust pipe. The outer diameter of the rubber sealing cover 9 can be changed, so it can adapt to vehicle exhaust pipes with different inner diameters.

[0031] The exhaust end of the air duct 1 is connected to a purification cartridge 13, in which activated carbon 14 is arranged. Filters 15 are arranged on the inner sides of both ends of the purification cartridge 13. The activated carbon 14 filters and absorbs harmful substances in the vehicle exhaust, thereby reducing the emission of harmful substances, which is beneficial to on-site workers. In some other embodiments, photocatalysts can be used instead of activated carbon 14.

[0032] In this embodiment, the purification cartridge 13 is connected to the air duct 1 through threads. Specifically, one end of the purification cartridge 13 is provided with an external thread, and the exhaust end of the air duct 1 is provided with an internal thread.

[0033] A probe 2 for detecting vehicle exhaust is provided in the middle of the air duct 1. The probe 2 detects the composition and concentration of vehicle exhaust. A detection host 3 is provided on the outside of the air duct 1. The probe 2 is connected to the middle wall of the air duct 1 by threads. A cable 16 is connected to the outside of the probe 2. A plug is provided at the end of the cable 16. The probe 2 includes a rod, a hexagonal column section is connected to the outer end of the rod, a sensor is provided at the inner end, the rod is provided with an external thread, and an internal thread hole is provided on the middle wall of the air duct 1. The rod is a tubular structure, which is convenient for connecting the cable 16 with the sensor.

[0034] The sensor is one or more of a hydrogen compound sensor, a nitrogen oxide sensor, a carbon monoxide sensor and a PM2.5 sensor, and is used to detect corresponding components and their concentrations in the exhaust gas.

[0035] The detection host 3 includes a shell, which is connected to the outside of the middle part of the air duct 1 by bolts. The outside of the air duct 1 is provided with a mounting seat for supporting the installation of the detection host 3; a controller 302 and a battery 301 are arranged in the shell, and a heat dissipation hole is arranged on the side wall of the shell, and a display 303 is inlaid on the upper wall of the shell; the controller 302 is connected to a socket for matching with the plug of the cable 16, and the socket is located on the side wall of the shell. When the vehicle exhaust passes through the air duct 1, the probe 2 detects the composition and concentration of the vehicle exhaust, and the controller 302 receives the information detected by the probe 2 and displays it on the display 303; the battery 301 supplies power to the controller 302 and the display 303, and the battery 301 is connected to a charging port and can be repeatedly charged, and the charging port is located on the side wall of the shell.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
