[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the cleaning mechanism 6 includes a fixing block 601, a second spring 602 fixedly connected to the inner cavity of the fixing block 601, a connecting frame 603 fixedly connected to one side of the second spring 602, a cleaning brush 604 fixedly connected to one side of the connecting frame 603, one side of the cleaning brush 604 contacting the protective cover 2, a pull rod 7 fixedly connected to the surface of the connecting frame 603, the surface of the pull rod 7 being provided with anti-slip texture, the top of the limiting rod 504 extending to the outside of the outer shell 501, a pull block 8 fixedly connected to the top of the limiting rod 504, a sliding rod 9 fixedly connected to the opposite side of the connecting block 402, sliding sleeves 10 slidably connected to both sides of the surface of the sliding rod 9, the top of the sliding sleeves 10 being fixedly connected to the threaded tube 404, the limiting clamp 405 being L-shaped, a rubber pad fixedly connected to one side of the limiting clamp 405, a mounting base fixedly connected to one side of the dual-axis motor 401, one side of the mounting base being fixedly connected to the alarm body 1, a sealing seat 11 fixedly connected to one side of the protective cover 2, and one side of the sealing seat 11 being sleeved on the surface of the alarm body 1.

[0031] Specifically: The movable cleaning brush 604 can be moved manually by the operator, and the cleaning brush 604 moves on the surface of the protective cover 2 to clean the dust accumulated on the surface of the diffusion groove 3, thereby improving the dustproof effect.
