Description

Technical Field

[0001] This invention relates to the field of smoke detection technology, specifically a smoke detection alarm mechanism. Background Technology

[0002] Aspirating smoke detectors are a type of very early fire detector. These detectors can draw air from the protected area into the detector for analysis, thereby providing early warning of fires. Aspirating smoke detectors can identify fires when they are still in the smoldering stage, that is, when the combustion produces a small amount of smoke. They are one of the most widely used smoke detection and alarm devices.

[0003] Conventional smoke detectors are installed at fixed detection points. Over time, the detection chamber inside the detector easily becomes dirty due to long-term accumulation of smoke and impurities, affecting subsequent normal detection. Furthermore, conventional smoke detectors are inconvenient to clean. Additionally, ordinary suction-type structures are slow in drawing in smoke; by the time smoke is detected and an alarm is issued, the fire has already grown significantly, hindering rapid fire analysis and early warning. To improve the ease of use and optimize the detection effect of smoke detectors, those skilled in the art have proposed a smoke detection alarm mechanism to address the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a smoke detection alarm mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smoke detection alarm mechanism includes a main housing and a mounting frame. The mounting frame is for installation on a building. The main housing is detachably mounted on the mounting frame. An outer cover is detachably mounted on the bottom of the main housing, and a filter layer is provided at the bottom of the outer cover. A wiring board is mounted on the top of the main housing. A control cylinder is detachably mounted on the top of the inner cavity of the main housing. A main controller and a data analyzer are installed inside the control cylinder. An alarm is mounted on the side of the main housing. A detection cylinder is detachably mounted on the bottom of the control cylinder. A detector is installed inside the detection cylinder, and several detectors are connected to the bottom of the detector. The detector tube has a rotating cylinder movably connected to its bottom, and a fixed plate movably connected to its bottom. The fixed plate is detachably fixed via a fixing rod connected to the inner wall of the detector tube. An air inlet pipe is provided on the side of the rotating cylinder, and a fan is installed in the inner cavity of the end of the air inlet pipe away from the rotating cylinder. The rotating cylinder can rotate relative to the detector tube. The upper part of the detector tube is placed in the inner cavity of the rotating cylinder, and the lower part of the detector tube passes through the fixed plate and is placed in the inner cavity of the outer cover. The detector, wiring board, and alarm are all connected to the main controller and data analyzer.

[0009] As a further embodiment of the present invention: an annular gear ring is connected to the outer periphery of the top of the rotating cylinder, and a driving component is mounted on the outer wall of the bottom of the rotating cylinder through a mounting bracket. The output end of the driving component is connected to a drive gear, and the drive gear meshes with the annular gear ring.

[0010] As a further embodiment of the present invention: a pressure regulating component is provided on the fixed plate, the pressure regulating component including a storage tube installed in the middle of the fixed plate, a folding sleeve installed in the inner circumference of the storage tube, and a pressure plate connected to the top of the folding sleeve.

The detection cylinder is equipped with a detector, which detects smoke through multiple detection tubes. When a small amount of smoke is detected at the end of the detection tube, the air intake direction can be adjusted by the rotating cylinder and the air intake pipe, so that the air intake pipe can quickly draw air from the source of the small amount of smoke. The drawn-in air enters the inner cavity of the rotating cylinder to fully contact the middle of the detection tube, ensuring the contact effect between the suspected air and the detection tube. At this time, the air can be fully detected, and the smoke signal source can be accurately and efficiently determined. Based on the result, an alarm can be issued. Compared with conventional smoke detection alarms, this detection alarm mechanism has greater flexibility of use, is easier to clean and maintain, and can quickly make a detection judgment before a fire may occur, resulting in better performance.

[0027] Working Principle: During use, the mounting frame 2 is installed at the detection point on the building. The main housing 1 is then installed onto the mounting frame 2. Inside the main housing 1, the control cylinder 3, detection cylinder 4, rotating cylinder 5, and fixed plate 6 are sequentially installed. During detection, if a suspicious air source is present, the suspicious air enters below the detection cylinder 4 through the filter layer 801 of the outer casing 8. The suspicious air contacts the bottom end of the detection tube 402. The data analyzer 302 detects and obtains the direction and position of the detection tube 402 containing the suspicious air. The position of the rotating cylinder 5 is then adjusted so that the air inlet pipe 501 faces that direction. The drive component 410 drives the drive gear 411 to rotate, which in turn drives the ring gear 504 to rotate. The ring gear 504 drives the rotating cylinder 5 to rotate. During rotation, the two track plates 503 slide within the first track groove 408 and the second track groove 603, respectively. After the rotating cylinder 5 is adjusted, the fan 502 draws in air, removing a large amount of pollutants. Suspected air is drawn into the inner cavity of the rotating cylinder 5 and contacts the middle of the detection tube 402. By increasing the intake of suspected air, smoke detection is performed in advance. Initially, the inner cavity of the rotating cylinder 5 is in a pressure balance state. After the air inlet pipe 501 draws in air, the inner cavity of the rotating cylinder 5 increases and squeezes the pressure plate 702. The pressure plate 702 squeezes the folding sleeve 703 and moves downward, making the volume of the inner cavity of the rotating cylinder 5 larger. This ensures that the air inlet pipe 501 can continuously draw in suspected air and that the suspected air can remain fully in the inner cavity of the rotating cylinder 5. At this time, the suspected air is detected by the detection tube 402. After smoke is detected, the smoke content is analyzed by the data analyzer 302. When the smoke content reaches the alarm standard, the main controller 301 controls the alarm 105 to start and issue an alarm. After one round of detection, the control valve 704 is opened, and the suspected air in the rotating cylinder 5 is discharged through the control valve 704 and the air outlet pipe 705 for use in the next detection.
