Description

Fire alarm with dust keeper

Technical Field

The utility model relates to the technical field of fire alarms, in particular to a fire alarm with a dustproof device.

Background

Once a family fire happens, adverse factors such as untimely fire suppression, lack of fire extinguishing equipment, scare and misbehavior of bystanders, slow escape and the like easily occur, and finally, great life and property loss is caused, so that the fire alarm is applied, wherein the fire alarm is also called as a smoke alarm, is one of the most important means for preventing the fire, and has the function of detecting that a great amount of smoke causes the fire to generate an alarm, so that people can timely make a response and a remedial measure to avoid casualties when the fire happens;

although the existing fire alarm devices are very efficient in use, it is considered that in the face of long-term use, the probe of the fire alarm device is easy to reduce the detection sensitivity to smoke due to the adsorption of dust, so that the existing fire alarm device is generally provided with a dust screen at the outer side of the probe, the dust screen is utilized to effectively intercept and treat dust, in particular, the shell of the existing fire alarm is generally divided into an upper shell and a lower shell, the probe is arranged at the lower end of the upper shell, the side wall of the lower shell is usually provided with a plurality of notches for smoke inlet, and a dust screen with a ring structure is arranged inside the lower shell at the same time, and the dust screen and the lower shell are usually in an integral structure, when the probe is installed, the upper shell and the lower shell are fixedly connected through bolts, wherein the dustproof net with the annular structure is not contacted with the probe generally and only surrounds the outer side of the probe;

although the influence of dust on the smoke detection sensitivity of the probe can be effectively reduced through the existing improvement, similarly, after the dustproof net is installed in the face of long-time use, meshes of the dustproof net are very easily blocked by the dust, so that the smoke can be very easily blocked by the dust, and the probe cannot alarm and process the smoke in time in the first time, so that the personal safety of people cannot be effectively guaranteed to a certain extent, and the use efficiency and the practicability of the fire alarm are reduced to a certain extent, therefore, the dust attached to the dustproof net can be regularly and properly cleaned by people, and the normal use efficiency of the fire alarm is guaranteed; however, it is obvious that current dust screen is comparatively troublesome, time-consuming when needs clear up, need dismantle the separation with fire alarm's upper and lower casing, just later can suitably clear up the dust screen of casing inside down, and this makes this fire alarm unable the use of coming into operation in the short time of dust screen clearance equally, if the conflagration source that people can't in time catch appears in this time quantum, then very causes unnecessary casualties and loss of property easily.

Disclosure of Invention
