Description

An anti-interference smoke alarm

Technical Field

The utility model relates to the technical field of smoke alarms, in particular to an anti-interference smoke alarm.

Background Art

Smoke alarms are mainly used in fire protection systems and are also used in security system construction. Smoke detectors mainly prevent fires by monitoring the concentration of smoke. The principle is that the infrared beam of the infrared transmitting tube is scattered by smoke particles, and the intensity of the scattered light is proportional to the concentration of smoke.

For example, the authorization announcement number "CN215814427U" is an anti-interference wireless smoke alarm. Although it is designed with an anti-insect net installation structure to resist interference, the smoke alarm is installed on the ceiling and encounters high temperature environment, which is transmitted to the smoke alarm and interferes with its normal operation.

DETAILED DESCRIPTION

Please refer to Figures 1-2. The utility model provides a technical solution: an anti-interference smoke alarm, 1. a smoke sensor body 2, a protective shell 3, an atomizer 31, an air outlet pipe 32, an air outlet 4, a camera 41, a main panel 42, and a lens. The smoke sensor body 1 also includes a protective shell 2 covering the smoke sensor body 1 for heat insulation. The sensing surface of the smoke sensor body 1 is higher than the outer surface of the protective shell 2. The inner surface of the protective shell 2 is provided with a plurality of atomizers 3 for cooling and a camera 4 for real-time monitoring.

Six atomizers 3 are installed at equal intervals. The output end of the atomizer 3 is connected to the air outlet pipe 31 at the bottom. The air outlet pipe 31 is in a "7" shape. The other end of the air outlet pipe 31 is connected to the air outlet 32 on the outer ring surface of the protective shell 2.

The camera 4 is on the same horizontal line as the atomizer 3 , the lens of the camera 4 faces the bottom surface of the protective shell 2 , and an anti-fog lens 42 is provided at the lens.

The real-time image of the camera 4 is transmitted to the main panel 41 on the top, and the main panel 41 is connected to control the atomizer 3. The main panel 41 transmits the image to the host through the wireless network to detect the environment of the smoke sensor body 1 in real time.

The protective shell 2 is a round box, and the protective shell 2 is made of heat-insulating and fire-proof material.

Working principle: When the new smoke alarm is used, the protective shell 2 covers the smoke sensor body 1 inside, and the sensing surface of the smoke sensor body 1 is higher than the outer surface of the protective shell 2. The inner surface of the protective shell 2 is provided with a plurality of atomizers 3 for cooling and a camera 4 for real-time monitoring. There are 6 atomizers 3 installed at equal distances, and the output end of the atomizer 3 is connected to the air outlet pipe 31 at the bottom. The air outlet pipe 31 is in the shape of a "7", and the other end of the air outlet pipe 31 is connected to the air outlet 32 on the outer surface of the protective shell 2. The camera 4 is on the same horizontal line as the atomizer 3, and the lens of the camera 4 faces the bottom surface of the protective shell 2, and there is an anti-fog lens 42 at the lens. The real-time image of the camera 4 is transmitted to the main panel 41 on the top, and the main panel 41 is connected to the control atomizer 3. The main panel 41 transmits the image to the host through the wireless network to detect the environment of the smoke sensor body 1 in real time. The protective shell 2 is a round box, and the protective shell 2 is made of heat-insulating and fire-proof material.

When the camera 4 monitors in real time that the smoke alarm is in a high temperature environment, the atomizer 3 is started, and the atomizer 3 sprays the mist through the output end connected to the outlet pipe 31 to the area around the smoke alarm to cool it down.
