Description

Smoke detector structure

technical field

The utility model relates to a structure of a smoke detector, which uses two adjustment screws and two elastic components to adjust its horizontal position, so that when the smoke detector is set on a wall or ceiling, it can achieve the function of horizontal setting.

Background technique

With the development of science and technology, buildings are constantly being built, and the structure of the building's fire protection system is also much more sophisticated, and the structure of the fire alarm system is also more flexible and diverse. Especially with the development of communication software, the fire alarm system is more combined with the Internet to launch an intelligent system. With the function of central monitoring, the current fire alarm system will develop towards an intelligent system.

There are four types of detection basis for alarms in case of fire. The first fire is usually accompanied by smoke, fire, high temperature and gas generated after combustion, so these are usually the basis for measuring and judging whether a fire is on or not. The second fire is in a smoldering state at the initial stage, and usually the temperature is not high but accompanied by a lot of smoke. The inductive sensor uses this feature to detect the fire. In the middle and late stages of the third fire, with the high temperature and fire light, the flame sensor and temperature sensor are made into fire alarms with this feature. The fourth is to prevent fires in advance from the cause and medium of fires, such as gas and natural gas and other flammable gases that may cause fires to be detected to further prevent fires.

There are many types of general fire detectors, which can be roughly divided into temperature detection fire detectors, smoke detectors, flame detectors, combustible gas detectors and composite fire detectors, among which temperature detection fire detectors It can also be divided into two types: point type and line type detectors, and the point type and line type are subdivided into constant temperature type, differential type and differential constant temperature type detectors, smoke detection type detectors and temperature detection type fire detection Similar to detectors, it is divided into point-type and linear detectors. The point-type detectors are divided into two types: ion smoke detectors and photoelectric smoke detectors. Linear detectors are divided into laser and separate detectors. There are two types of photoelectric smoke detectors, and flame detectors are divided into ultraviolet (UV) and infrared (IR) detectors.

At present, most of the smoke detectors on the market are smoke detectors. Smoke detectors sense fire alarms through the smoke generated by the fire. They can be subdivided into two types: ionization (ionization) and photoelectric. Among them, ionization smoke There is an ionization chamber and americium-241 inside the sensor, and the ionization chamber will be connected with positive and negative voltages. Americium-241 will produce alpha atoms, which can ionize nitrogen and oxygen atoms in the air. When oxygen or nitrogen atoms are electrolyzed into positive ions and electrons, the positive ions will be attracted by the negative voltage ionization chamber, and the negative ions will be attracted by the positive voltage The ionization chamber attracts and generates current through the movement of positive and negative ions. When there is smoke in the air, the oxygen concentration will drop, and the current will also drop. It aims at the characteristics of local smoke and produces the principle of ion current change. When the surrounding air contains smoke When the concentration is above a certain level, it will act. One side of the photoelectric smoke sensor uses a light sensor, and there is a light source at an angle of 90 degrees to the sensor. When there is no light source, the light will directly shoot out. When the smoke enters the smoke sensor, The light is partially reflected to the sensor by the particles of the smoke, thus generating an alarm. In other words, the photoelectric smoke sensor operates according to the principle that the amount of light received by the photoelement changes due to the characteristics of the smoke. , and the effect of sensing fires with smoke is better. Smoke detectors can catch fire signals earlier and more effectively than thermal detectors in the process of indoor fires. They are currently used in general indoor places or residences, so smoke detectors are very effective for early warning of fires. , is also the most widely used.

However, the smoke sensor of the present invention is a utility model for photoelectric smoke sensors. Most of the photoelectric smoke sensors on the market today are installed on walls or ceilings, but none of them have the function of level correction. The photoelectric smoke sensors are used for sensing During the smoke process, there will often be misjudgments or the reflected infrared rays cannot be sensed, or during the installation process, the relative position of the main body of the photoelectric smoke sensor and the reflector is incorrect, resulting in poor sensing effect As a result, it is impossible to send an alarm in real time when a fire occurs.

In summary, there are many unfinished structures in the structure of the smoke sensor described above. Therefore, after long-term research and utility model, the utility model has developed a structure of a smoke detector with multi-directional adjustment inside. structure and positioning device, when the smoke detector is installed on the wall or ceiling, it can be precisely adjusted to be parallel to the relative position of the reflector, so that its infrared sensing device can accurately emit infrared rays and be reflected The infrared ray is reflected by the sheet to the receiving part of the smoke detector, so that it can be judged whether there is a fire.
