Description

Technical Field

[0001] This invention relates to a precision electronic device, specifically a precision electronic device for testing, belonging to the field of electronic device application technology. Background Technology

[0002] Electronic equipment refers to devices composed of electronic components such as integrated circuits, transistors, and vacuum tubes, which utilize electronic technology and software to function. This includes electronic computers and robots, numerical control or programmable control systems controlled by electronic computers. Alcohol testing devices are a type of electronic equipment, typically used to detect whether a driver is driving under the influence of alcohol. There are generally two methods for detecting drunk driving: one is to test the blood alcohol concentration, and the other is to test the breath alcohol concentration. Theoretically, the most accurate method to determine whether someone is driving under the influence of alcohol is to check the driver's blood alcohol content.

[0003] Currently, people rarely carry alcohol testing devices in their daily lives, resulting in extremely low usage. Therefore, people often rely on their own feelings to judge their breath, which is not only unsafe for driving but also leads to significant trouble if caught driving under the influence. Most existing alcohol testing devices are placed directly inside the car, making them prone to damage from shaking. Furthermore, the lingering smell of alcohol inside the device after use is difficult to dissipate, leading to inaccurate results. Therefore, this paper proposes a precision electronic device for alcohol detection to address these issues. Summary of the Invention

[0034] In use, all electrical components mentioned in this application are electrically connected to the battery 1 and the control button 26. When the alcohol electronic device is installed in a car, firstly, the rotating rod 12 is rotated, causing the rotating rod 12 to drive the pad 27 to rotate. The rotating pad 27 presses against the mounting plate 28, thereby causing the mounting plate 28 to move the sleeve 32 away from the housing 2 under the action of the pad 27. This allows the sleeve 32 to move the suction cup 33 out of the mounting box through the through hole 31 via the sliding rod 34 and the clamping plate 36. On the surface of the 30, rotate the locking post 35 to engage with the locking post 37. Then, attach the suction cup 33 to the surface of the car's center console, thus completing the installation of the alcohol electronic device. Next, control the micro-fan 23 via the control button 26, which in turn controls the micro-fan 5 to draw gas from inside the car into the housing 2 through the nozzle 7. When there is no alcohol odor inside the car, the alcohol sensor 10 transmits a signal to the micro-fan 5, which then controls the electronic control system. When switch 22 is turned on, the gas inside housing 2 is discharged through exhaust pipe 21. If there is an alcohol smell inside the vehicle, the alcohol sensor 10 transmits a signal to the microcontroller 5, which then controls the buzzer 3 to sound, thus alerting the driver and passengers that there is alcohol in the vehicle. When removing alcohol from the alcohol electronic device, the micro motor 11 is first turned on, causing the output of the micro motor 11 to drive the threaded sleeve 14 to move back and forth in the vertical direction through the threaded rod 13. The threaded sleeve 14 drives the square piston 17 to reciprocate inside the square cylinder 18 through the connecting rod 15. This causes the square piston 17 to repeatedly press the air freshener inside the square cylinder 18, thus spraying the air freshener out through the drain pipe 19 and the atomizing nozzle 20. The sprayed atomized air freshener cleans the gas inside housing 2 and is discharged through exhaust pipe 21. Then, the microcontroller 5 controls the heating tube 9 to turn on, causing the heating tube 9 to dry the moisture inside housing 2, thus completing the removal of alcohol from the alcohol electronic device.
