Description

Smoke detector structure

The invention relates to a structure of a smoke detector, which adjusts its horizontal position by adjusting screws and two elastic elements, so that the smoke detector can be horizontally arranged when it is placed on a wall or a ceiling.

With the development of technology, the building is constantly being built, the structure of the building fire protection system is also much improved, and the structure of the fire alarm system is more flexible and diverse. Especially with the development of communication software, the fire alarm system is combined with the network to introduce smart type. With the system and central monitoring functions, the current fire alarm system will be developed towards smart systems.

The sensing basis of the fire alarm can be divided into four types. The first fire is usually accompanied by smoke, flare, high temperature and gas generated after combustion, so these are usually used to measure and judge the fire. The second fire is in a state of smoldering at the beginning of the fire. Usually, the temperature is not high, but with a large amount of smoke, the inductive sensor uses this feature to detect the fire. In the middle and late third fire, with the high temperature and the fire, the flame sensor and the temperature sensor are used to make the fire alarm. Fourth, the cause and medium of the fire are prevented in advance, such as gas and natural gas, which may cause flammable gases to be detected, and further prevent fires.

There are many types of general fire detectors, which can be roughly classified into a fire detector, a smoke detector, a flame detector, a combustible gas detector, and a composite fire detector. The Detective Fire Detector can be divided into two types of point and line detectors, and the point type and line type are subdivided into fixed temperature, differential and differential fixed temperature detectors, and smoke detectors. The detector type fire detector is similar, and it is divided into a point type and a line type detector. The point type detector is further divided into an ion type smoke detector and a photoelectric type smoke detector. The line type detector is further divided into a laser type. There are two types of separate photoelectric detectors, and the flame detectors are divided into ultraviolet (UV) and infrared (IR) detectors.

At present, most of the detectors on the market are smoke detectors. The smoke detectors are alarms that fire alarms generated by fires. They can be subdivided into ionic (ionized) and photoelectric, ionic smoke. There is an ionization chamber and 鎇-241 inside the sensor, and the ionization chamber is connected with positive and negative voltages.鎇-241 produces alpha atoms, which can ionize nitrogen and oxygen atoms in the air. When oxygen or nitrogen atoms are electrolyzed into positive ions and electrons, positive ions are attracted to the negative ionization chamber, and negative ions are positively charged. The ionization chamber attracts, and the current is generated by the movement of positive and negative ions. When there is smoke in the air, the oxygen concentration will decrease and the current will also decrease. For the local range of smoke characteristics, the principle of ion current change is generated, when the ambient air contains smoke. When the concentration is above a certain concentration, the photoelectric sensor is used on the side of the photoelectric sensor, and the light source is at an angle of 90 degrees with the sensor. When there is no light source, the light is directly emitted outward when the smoke enters. When the smoke sensor is inside, the light is reflected by the particles of the smoke to the sensor, thus generating an alarm. In other words, the photoelectric smoke sensor acts according to the principle that the photoelectric property of the photoelectric element changes according to the smoke characteristic, and the advantages thereof are obtained. In order to prevent the light from being blocked, the wrong action is generated, and the fire that senses the smoke is better. The smoke detector detector can capture the fire signal earlier and more effectively than the heat sensitive detector during the indoor fire. It is currently used in general indoor places or residences, so the smoke detector is very effective for early warning of fire. The application is also the most extensive.

However, the smoke sensor of the present invention is invented for a photoelectric smoke sensor, and most of the photoelectric smoke sensors on the market today are installed on a wall or a ceiling, but none of them are horizontally corrected. The function of the photoelectric smoke sensor in the process of sensing smoke is often misjudged or undetectable of reflected infrared rays, or during the installation process, the photoelectric smoke sensor body and reflection The relative position of the board is set incorrectly, resulting in a less accurate sensing effect and an immediate alarm when a fire occurs.

Therefore, after long-term research and invention, the inventors have invented a structure of a smoke detector, which has a multi-directional adjustment structure inside. And the positioning device, when the smoke detector is installed on the wall or the ceiling, can be accurately adjusted to be parallel with the relative position of the reflection sheet, so that the infrared sensing device can accurately emit infrared rays and is reflected by the reflection sheet The infrared ray is sent to the receiving portion of the smoke detector to determine whether a fire has occurred.
