In the long-time standby state of the device, the water absorbing sponge 1401 can absorb the nearby water and gas, so that the electronic elements in the fixing shell 201 are prevented from being corroded by the water and gas in the air, the device is damaged, the alarm capacity of the device is lost, the fire can not be treated for the first time after the fire occurs, and the monitoring capacity of the device is improved.
After the temperature of the environment where the device is located rises, in the process that the sliding shell 301 slides downwards along the fixed shell 201, the sliding shell 301 also drives a plurality of baffles 1404 to move downwards together, meanwhile, the boss of the sliding shell 301 also extrudes the water absorbing sponge 1401, water absorbed in the water absorbing sponge 1401 is extruded, the water absorbing sponge 1401 is prevented from absorbing water until the water absorbing sponge 1401 is saturated, the water absorbing capacity is lost, and therefore electronic elements in the fixed shell 201 are corroded by water vapor in the air, damage occurs, and the device loses the alarming capacity.
In the process of extruding the water absorbing sponge 1401 by the boss of the sliding shell 301, after the baffle 1404 moves downwards until the outer side of the baffle 1404 contacts with the inner wall of the extruding ring 1402, the boss of the sliding shell 301 continuously extrudes the water absorbing sponge 1401 along with the downward movement of the sliding shell 301, and the water in the water absorbing sponge 1401 begins to be extruded, at this time, the baffle 1404 shields the upper end part of the second strip hole 302, so that after the water in the water absorbing sponge 1401 is extruded, the flowing water cannot enter the sliding shell 301, thereby ensuring the mutually isolated state between the sliding shell 301 and the water absorbing sponge 1401 in the process of extruding the water in the water absorbing sponge 1401, further ensuring that the extruded water cannot influence the electronic elements in the sliding shell 301, thereby improving the protection of the electronic elements and further improving the alarm effect of the device.
In the process of extruding the water absorbing sponge 1401, extruded water passes through the drain hole 1403 and the adjacent diversion trenches and then is discharged out of the device, the extruded water is distributed with the adjacent first strip holes 202 in a staggered manner through the drain hole 1403, the probability of water flowing into the first strip holes 202 is reduced after the extruded water is separated from the drain hole 1403, the water is guided through the diversion trenches, the possibility of water flowing into the first strip holes 202 is avoided, the extruded water is prevented from entering the sliding shell 301 through the first strip holes 202 and the second strip holes 302, and therefore damage is caused to electronic elements in the sliding shell 301, the protection of the electronic elements is improved, and after fire treatment is completed, workers can overhaul the whole device.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
