[0002] Working principle of combustible gas detector: When combustible gas leaks, the combustible gas detector installed at the site of the protection area converts the concentration parameters of the leaked combustible gas into electrical signals. After data processing, the combustible gas concentration parameter information is transmitted to the combustible gas alarm controller; or the combustible gas detector directly makes an alarm judgment that the concentration of the leaked combustible gas exceeds the limit, and transmits the alarm information to the combustible gas alarm controller. After receiving the combustible gas concentration parameter information or alarm information from the detector, the combustible gas alarm controller confirms and judges, displays the location of the leak alarm detector and the leaked combustible gas concentration information, records the time of the detector alarm, and drives the sound and light alarm device installed at the site of the protection area to sound an sound and light alarm to warn personnel to take corresponding disposal measures.

[0003] Existing combustible gas detectors, such as an online analysis combustible gas detection device with patent number CN215866577U, are provided with a protective plate, which facilitates the display screen and operation buttons of the detection device body when the detection device body is not in use; the external connection structure is disclosed, but the internal structure is not disclosed; in other existing detectors, the panel is welded to the lens, the lens is welded to the shell, the light guide is fixed to the panel, and the light guide is connected to the electronic unit through the light guide. The panel can display information related to the working status of the detector, which is relatively complicated to assemble and when the shell for installing the panel needs to be replaced, the panel, lens and light guide need to be replaced together, resulting in high maintenance costs.
