[0001] This utility model relates to the field of automotive testing technology, and in particular to an automotive VOC testing device. Background Technology

[0002] As people's living standards continue to improve, every household will have a car as a means of transportation. When a car is first purchased, or when purchasing auxiliary tools such as seat covers, it will inevitably emit VOC (volatile organic compound) gas due to the different materials used.

[0003] While existing VOC detection devices can detect VOC gases in cars, their structures are simple and lack the effect of purifying VOC gases. Moreover, most of them are single-test devices and cannot determine the VOC content in the gas discharged after filtration. Furthermore, when it comes to continuous testing, the existing devices have a single placement method and most of them need to be held by the user, which is quite inconvenient.

[0004] To address this issue, this utility model proposes a vehicle VOC detection device. Utility Model Content

[0027] like Figures 1 to 5 As shown, an automotive VOC detection device includes a housing 1. An air intake pipe 2 is rotatably connected to one side of the housing 1. A motor 3 is fixedly connected to one side of the housing 1. The motor 3 is electrically connected to a control button for control. A gear 4 is fixedly connected to the output end of the motor 3. The bottom of the air intake pipe 2 meshes with the gear 4. A cover plate 5 is fixedly connected to one side of the housing 1. An exhaust fan 6 is fixedly connected to the bottom of the cover plate 5. Two VOC detectors 7 are fixedly installed inside the housing 1. A filter plate 8 is installed between the two VOC detectors 7. An exhaust pipe 9 is fixedly connected to one side of the housing 1. A handle 10 is rotatably connected to one side of the housing 1. A replaceable power supply is provided inside the housing 1 to power the electrical devices. The specific details of the control connections of each electrical device are not described here, but refer to the technical features disclosed in CN211856524U.

[0028] A rotating shaft 101 is fixedly connected to each of the two sides of the outer casing 1. One of the rotating shafts 101 has a thread on its exterior and is threadedly connected to a locking knob 102.

[0029] A rotating hole 11 is provided on each side of the handle 10. The interior of the two rotating holes 11 is rotatably connected to the exterior of the two rotating shafts 101. The locking knob 102 fits against the side of the handle 10. The handle 10 is designed for easy carrying. Since there are few flat surfaces inside the vehicle, the angle of the handle 10 can be adjusted to support the outer shell 1 and keep it level. Tightening the locking knob 102 can fix the angle of the handle 10.

[0030] A through hole 103 is provided on one side of the outer casing 1. The diameter of one side of the air intake pipe 2 is adapted to the inner diameter of the through hole 103. One side of the air intake pipe 2 is rotatably connected to the inside of the through hole 103.

[0031] Two limiting rings 201 are fixedly connected to the bottom of the air intake pipe 2, and the limiting rings 201 are snapped into both sides of the through hole 103.

[0032] One of the limiting rings 201 is fixedly connected with several teeth 202, which mesh with the gear 4. The limiting ring 201 can prevent the intake pipe 2 from sliding up and down and shifting. The motor 3 drives the gear 4 to rotate, and under the meshing with the teeth 202, it will drive the intake pipe 2 to rotate and draw in air, covering a wider range.

[0033] A connecting pipe 104 is fixedly connected inside the outer casing 1, and the bottom of the air intake pipe 2 is inserted into the inside of the connecting pipe 104.

[0034] A first through groove 105 is provided on one side of the outer casing 1, and a cover plate 5 is fixedly connected to the inside of the first through groove 105. The exhaust fan 6 is inserted into the inside of the outer casing 1 and connected to the connecting pipe 104.

The filter plate 8 is an activated carbon adsorption filter plate. The exhaust fan 6, VOC detector 7 and filter plate 8 all adopt the model disclosed in CN211856524U.

[0036] Dustproof nets 12 are fixedly connected to one side of the intake pipe 2 and the exhaust pipe 9. Each VOC detector 7 is equipped with a display screen 13. The VOC value detected by the VOC detector 7 can be read through the display screen 13, so as to determine whether the VOC value in the vehicle is qualified. The dustproof nets 12 can prevent dust and debris from entering the interior of the intake pipe 2 and the exhaust pipe 9.

[0037] Instructions for use: Place this device inside the car and balance the outer casing 1 by rotating the handle 10. During testing, start the motor 3, exhaust fan 6, VOC detector 7, and display screen 13. The exhaust fan 6 draws air from the car through the intake pipe 2 and delivers it to the VOC detector 7. After the first test, the display screen 13 shows the result. Then, after being filtered by the filter plate 8, the air is tested by the second VOC detector 7 to detect the VOC content in the filtered air, which is also displayed on the display screen 13. Finally, the air is discharged from the exhaust pipe 9. The motor 3 drives the gear 4 to rotate, and when it meshes with the teeth 202, it drives the intake pipe 2 to rotate while drawing in air, thus covering a wider area.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] The handle 10 is designed for easy carrying. Since there are few flat surfaces inside the vehicle, the angle of the handle 10 can be adjusted to support the outer shell 1 and keep it level. Tightening the locking knob 102 can fix the angle of the handle 10. The motor 3 drives the gear 4 to rotate. When it meshes with the teeth 202, it will drive the air intake pipe 2 to rotate and draw in air, thus covering a wider range.
