Description

Technical Field

[0001] The utility model belongs to the technical field of detectors, and in particular relates to an indoor smoke fire detector. Background Art

[0002] Indoor smoke fire detectors, also known as smoke detectors or smoke-type fire detectors, are a type of safety equipment used for fire early warning. Its main working principle is to achieve fire early warning by detecting smoke or other combustion products in the air. This type of detector is widely used in fire protection systems and plays a good role in safeguarding people’s lives and property.

[0003] The indoor smoke fire detectors currently on the market have the following problems when used:

[0004] 1. In the actual use of traditional indoor smoke fire detectors, the detector body and the air intake grille structure are usually an integrated structure. After long-term use, dust in the air will directly adhere to and accumulate on the outside of the air intake grille, which is also inconvenient to clean the grille structure later. Therefore, it is inconvenient to disassemble and assemble the grille structure during use;

[0005] 2. When most indoor smoke detectors are used, the detector bodies are often installed in different environments. Since smoke detectors may be sensitive to things other than fire, such as water vapor, if the detectors installed in a humid environment give a false alarm, it will not only waste resources, but may also cause unnecessary trouble and impact to the users. Therefore, the drying effect is weaker when used. Utility Model Content

Induction is performed, and the drying effect is strong during application. Then the film on the top of the adhesive surface 10 is torn off, and then it is first bonded to the wall, and then the fasteners are taken out to fix it, so that the detector body 1 can be used. Secondly, the detector body 1 is exposed to the air for a long time, so that the dust in the air can easily block the air intake mesh. By installing the lower ring seat 3, damping plate 8, vertical plate 4, card block 6, and air intake mesh cover 7 at the bottom of the detector body 1, in order not to affect the subsequent use, first push the resistance plate on the top of the push block 9 in the opposite direction, and then take out the card block 6 on the inner side of the air intake mesh cover 7 from the card slot 5 inside the vertical plate 4, so that the air intake mesh cover 7 can be disassembled and cleaned. The operation is relatively simple during cleaning. After cleaning, the card block 6 on the inner side of the air intake mesh cover 7 is inserted into the card slot 5, and then the push block 9 is pushed outward, so that the damping plate 8 supports the air intake mesh cover 7, so that it is convenient to disassemble and assemble the air intake mesh cover 7 during use.
