[0002] A composite fire detector is a detector that responds to two or more fire parameters. It has several types, including smoke and temperature sensing, smoke and light sensing, and temperature and light sensing. Composite fire detectors are installed in existing indoor buildings, shopping malls and other large public places.

[0003] Although the existing composite fire detectors can be used for daily detection operations in public places, in actual use, due to the low frequency of use of the composite fire detectors and the long-term installation in a fixed position, there will be a lot of dust blocking the detection holes of the composite fire detectors. Therefore, staff need to clean them regularly. The composite fire detectors are mostly installed on the top of the building, and it is very inconvenient to climb up and down when cleaning, which makes the cleaning of the composite fire detectors less convenient. Moreover, since the staff need to climb up when cleaning, it is inconvenient to carry too many tools, so they simply use a brush to brush them off. However, some fine dust and impurities are difficult to brush off, causing the fine dust and impurities to remain on the composite fire detector, which easily affects the normal use of the composite fire detector, thereby making the use effect of the composite fire detector not good enough.

When the indicator light 2 is in normal working condition, the light on the detector may serve as an indicator light 2 to display the power status, working mode, connection status and other information of the detector. When the detector detects an abnormal situation or triggers an alarm condition, the light will become an alarm light and emit light of a specific color, flashing frequency or brightness to remind people to pay attention. A number of filter holes 3 are opened in the middle of the detector body 1; a rotating groove 4 is opened in the middle of the detector body 1, and a connecting structure is provided on the inner wall of the rotating groove 4. The connecting structure includes a fixed rod 5, a limit disk 6 is fixed at the lower end of the fixed rod 5, and a rotating frame 7 is rotatably connected to the outer surface of the fixed rod 5.

[0029] When the utility model is in use: a manual handheld fan is aimed at the detector body 1 for blowing operation, so that when the air flow generated by the fan passes through the fan blades 9, due to the special shape and angle design of the fan blades 9, the air flow will generate a force on the fan blades 9, and the generated force drives the fan blades 9 to rotate, so that the fixing ring 8 fixed to the fan blades 9 can rotate. The rotating fixing ring 8 drives the rotating frame 7 fixed at the upper end to rotate on the inner wall of the rotating groove 4 under the limited stability of the fixing rod 5 and the limit plate 6.
