Description

Technical Field

[0001] The utility model belongs to the technical field of smoke alarms, and particularly relates to a smoke alarm with a protective cover structure. Background Technique

[0002] A smoke alarm is a fire warning device used to detect smoke particles in the air. Once smoke is detected, it will immediately sound an alarm to remind people of the possible fire risk. An ion-type smoke sensor is usually adopted inside the smoke alarm. This is a sensor with advanced technology, stable and reliable operation, and is widely used in various fire alarm systems. The smoke alarm is usually installed at positions such as the ceiling to ensure that the largest detection area can be covered, which is an important measure to protect personnel safety and reduce property losses.

[0003] The following problems exist when the existing smoke alarms on the market are applied:

[0004] 1. During the actual use of traditional smoke alarms, the smoke alarms are usually directly installed at positions such as the ceiling. Once a user uses a knocking tool to knock on the bottom of the alarm body, it is very easy to cause damage to the bottom of the smoke alarm. Therefore, it does not have a protective effect during use.

[0005] 2. When most smoke alarms are applied, multiple sets of fasteners are often required to fix the position of the smoke alarm. Since most of them are directly installed on the top plate, the installation difficulty is increased, so the installation is relatively inconvenient during application. Content of the Utility Model

[0006] The purpose of the utility model is to provide a smoke alarm with a protective cover structure to solve the technical problems raised in the background technique.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A smoke alarm with a protective cover structure includes a smoke alarm body and an air inlet hole.
