[0025] Example

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] A security access control alarm includes a device body 201, the outer side of the device body 201 is covered with a protective shell 101, one side of the device body 201 extends outside the protective shell 101, a group of air inlet grilles 204 are provided on both sides of the device body 201, a group of air guide grilles 205 are provided on the top side of the device body 201, an air extraction frame 301 is fixedly connected to the top side of the protective shell 101, an air source is provided inside the air extraction frame 301, and two air guide frames 304 are connected on both sides of the air extraction frame 301, and the two air guide frames 304 are both connected to the inside of the device body 201. In this embodiment, an air outlet 102 corresponding to the air extraction frame 301 and an air return port 103 corresponding to the air guide frame 304 are provided on the top side of the protective shell 101, a group of heat conducting plates 303 are provided inside each air guide frame 304, and a filter drawer 306 is provided between the inner walls of the air extraction frame 301. A set of guide rails 308 are provided at the bottom of the inner walls on both sides of the air extraction frame 301. The top sides of the guide rails 308 are slidably connected to the filter drawer 306, and one side of the filter drawer 306 extends to the outside of the air extraction frame 301. The top and bottom sides of the filter drawer 306 are provided with air holes 307 connected to the inside of the filter drawer 306. In this embodiment, the upper air holes 307 are smaller and the lower air holes 307 are larger, so that dusty air can flow in from the lower air holes 307, and the inside of the filter drawer 306 is filled with filter materials, such as adsorbent cotton, activated carbon, etc., to filter the air. The top side of each group of heat conductive sheets 303 extends to the outside of the corresponding air guide frame 304, and each group of heat conductive sheets 303 is inclined in the direction away from the air extraction frame 301, and each group of heat conductive sheets 303 is staggered. After passing through the filter tray 306 , the air will naturally flow to the two air guide frames 304 and fully contact the heat conductive sheet 303 , so as to balance the heat in the air with the outside world, so that the air maintains a suitable temperature.

[0028] One side of each air guide frame 304 is rotatably connected with a limiting plate 305, and each limiting plate 305 facing the side of the air extraction frame 301 can contact the side of the filter drawer 306 extending out of the air extraction frame 301. Each limiting plate 305 is provided with a group of magnetic strips 302 on the side facing the air extraction frame 301 and the corresponding side of the air extraction frame 301, and each group of magnetic strips 302 can be magnetically attracted to each other.

The air source is a group of fan blades, which can rotate under the drive of a rotating drive source, and the rotating drive source is an air extraction motor 310, and the air extraction motor 310 is fixed to the top side of the air extraction frame 301. At the same time, in this embodiment, an alarm 203 is provided on the side where the device body 201 extends out of the protective shell 101, so that the alarm sound can be fully transmitted to the space outside the device to alert relevant personnel. At the same time, a bottom plate 104 is fixedly connected to the side of the bottom end of the protective shell 101 facing the device body 201. The top side of the bottom plate 104 can be flush with the bottom side of the device body 201, and a pair of sliding grooves are opened on the side where the device body 201 extends out of the protective shell 101, and a sliding cover 202 is slidably connected to protect the alarm 203.
