Technical Field

[0001] The utility model relates to CO alarm production equipment, in particular to a CO alarm iron tank water injection device. Background Art

[0002] Carbon monoxide (CO) is a colorless, tasteless, and odorless gas that is very difficult to detect. Therefore, when detecting carbon monoxide concentration, an electrochemical carbon monoxide sensor is required to detect the concentration. This type of sensor generally requires the use of a liquid electrolyte, and a certain amount of pure water is added to the electrolyte to ensure the stability and accuracy of the electrolyte. It can also help maintain the stability of the sensor. The requirement for the amount of pure water injected during the injection process is ±0.5ml. Patent document CN206085213U discloses a water injection device, which includes a fixed plate and a workpiece fixing mechanism and a water injection mechanism respectively installed on both sides of the fixed plate. The workpiece fixing mechanism includes a first guide device, a first drive device, and a workpiece fixing plate. The first drive device is installed above the first guide device, and the workpiece fixing plate is installed below the first guide device. The water injection mechanism includes a second drive device, a second guide device, and a water injection assembly. The second drive device is installed above the second guide device, and the water injection assembly is installed below the second guide device. The first drive device and the second drive device can respectively drive the workpiece fixing part and the water injection assembly to move up and down through the first guide device and the second guide device, and can move the water injection assembly to the top of the workpiece fixing part to perform water injection processing on the workpiece to be processed in the workpiece fixing part. However, the water injection process of this water injection device does not adopt a flow control structure, so that its water injection accuracy needs to be improved. Therefore, it is necessary to optimize the structure of this water injection device to overcome the above defects. Utility Model Content
