Description

Technical Field

[0001] The utility model relates to the technical field of alarm equipment, in particular to a smoke alarm with a dustproof structure. Background Art

[0002] Existing smoke alarms are not specially designed to isolate dust. Their main function is to detect smoke particles in the air to provide timely alarms when a fire occurs. However, this design often causes the alarm to be overly sensitive to dust and easily trigger false alarms due to dust accumulation. Although some products may be equipped with simple dust covers or filters, these measures often have limited effects and cannot effectively block the entry of fine dust particles. Over time, dust will gradually accumulate on the alarm's sensing elements, affecting its normal operation and even causing the alarm to malfunction. Utility Model Content

When too much dust accumulates on the fiber layer 9, the rotating brush 7 is used to brush the surface of the fiber layer 9 through the cooperation between the rotating shaft 4 and the rotating handle 5. A fixed frame 8 is fixedly connected to the inside of the dust cover 1, a fiber layer 9 is fixedly connected to the inside of the fixed frame 8, and a fixed frame 8 is fixedly connected to the inside of the fixed frame 8. The connected fiber layer 9 plays a role in preliminary filtering of dust in the air. When air passes through the dust cover 1, the fiber layer 9 can intercept and absorb larger dust particles to prevent them from entering the interior of the alarm. A smoke air inlet 10 is opened on the side of the dust cover 1. A filter 11 is fixedly connected to the smoke air inlet 10. There are four groups of smoke air inlet 10 and filter 11, which are opened around the outside of the dust cover 1. The apertures of these filter 11 are small, which can further filter out tiny dust particles in the air to ensure that only smoke can enter the sensing area of ​​the alarm.

[0021] Reference Figure 2 A dust cover internal thread 12 is provided at the lower inner side of the dust cover 1, a first external thread 13 is provided at the top of the socket 2, a second external thread 14 is provided at the lower side of the socket 2, and a mounting seat internal thread 15 is provided at the upper inner side of the mounting seat 3.

[0024] The working principle of the utility model is as follows: a fixed frame 8 is provided inside the dust cover 1, and a fiber layer 9 fixed inside the fixed frame 8 plays a role in preliminary filtering of dust in the air. When air passes through the dust cover 1, the fiber layer 9 can intercept and absorb larger dust particles to prevent them from entering the interior of the alarm. Four groups of smoke air inlets 10 are also provided on the side of the dust cover 1, and a filter screen 11 is fixed inside each air inlet. The apertures of these filter screens 11 are small, which can further filter out tiny dust particles in the air to ensure that only smoke can enter the sensing area of ​​the alarm. Through this double filtering mechanism, the utility model effectively isolates the influence of dust on the alarm. When too much dust accumulates in the fiber layer 9, the rotating brush 7 is used to brush the surface of the fiber layer 9 through the cooperation of the rotating shaft 4 and the rotating handle 5. When the smoke enters the alarm through the filter screen 11, the smoke alarm body 19 starts to filter the smoke. Detection is carried out. Once the smoke concentration is detected to exceed the preset threshold, the smoke alarm body 19 will immediately trigger the alarm mechanism. At this time, the buzzer sound outlet 17 will emit a loud alarm sound, and the warning light 18 will also light up to remind the user to pay attention to the fire risk. In addition, in order to facilitate the user to turn off the alarm in time in the event of a false alarm, the utility model also provides a mute button 16 above the dust cover 1. When the user confirms that there is no fire risk on the scene, the mute button 16 can be pressed to stop the alarm from emitting an alarm sound and a warning light. In terms of structural connection, the dust cover 1 is threadedly connected to the first external thread 13 above the receiving seat 2 through the dust cover internal thread 12 to achieve a stable fixation. At the same time, the second external thread 14 at the bottom of the side of the receiving seat 2 is threadedly connected to the mounting seat internal thread 15 above the inner side of the mounting seat 3, so that the entire smoke alarm can be stably installed in the desired position.
