[0002] Harmful gases refer to gases that have adverse effects on the health of humans or animals, or gases that have no effect on the health of humans and animals but make humans or animals feel uncomfortable and affect their comfort, such as ammonia, hydrogen sulfide, carbon monoxide, etc.; one of the common indoor gas detection equipment is used to detect harmful gases such as formaldehyde and benzene.

[0003] After searching, the Chinese patent publication number CN214473182U discloses a harmful gas detection device, including a detector, a fixing frame is sleeved on the rear surface of the detector, the detector includes a display, a detection head is screwed on the bottom end of the display, and an alarm is installed on the top of the display. The utility model provides a detector with a fixing frame. When in use, according to the installation position, an adhesive method is used on some smooth walls, and the adhesive is applied to the rear surface of the fixing plate, and then it is pasted on the wall for installation. Bolts, screws or expansion screws can also be used for installation in the column fixing holes. After the fixing frame is assembled and stabilized, the fixing claws at the rear end of the detector are sleeved on the inner surface of the slot. During the sleeve process, according to the different widths of the fixing claws, the fixing slot is first stretched outward to be freely adjusted, and the adaptability is high. It effectively solves the problems that the existing different types of gas detectors have different structures and different fixing methods, which make installation more troublesome, and the replacement of the detection head structure is also more troublesome.
