Description

Technical Field

[0001] The utility model relates to the technical field of smoke detector test components, in particular to a smoke detector test component. Background Art

[0002] A smoke detector is a device used to detect fire smoke. They work by monitoring smoke particles in the air. Publication No. CN219978934U discloses a smoke detector, which includes a base and a protective cover fixedly connected to the base. An ionization chamber is provided on the inner side of the base, and an ionization area is formed between two conductor electrodes of the ionization chamber. A sealing cover is integrally formed on the protective cover, and an air inlet pipe is provided at the air inlet hole of the sealing cover. The air inlet pipe includes a tube body fixedly connected to the air inlet hole of the sealing cover, and a negative pressure fan installed on the inner side of the tube body. The tube body is located on one side of the negative pressure fan and is fixedly connected to a protective net. The utility model installs an air inlet pipe on the protective cover, which can quickly draw gas into the detector. The gas containing smoke particles enters the ionization chamber through the grid plate, and the smoke detection is quickly performed to increase the detection accuracy and sensitivity. At the same time, a drying and dehumidification structure is fixed in the base, which solves the problems of insufficient detection sensitivity of the current device and lack of moisture-proof and dehumidification function. Although the product has a good moisture-proof effect, it is inconvenient to clean the floating dust on the surface, which can easily cause the floating dust to block the smoke inlet, making it impossible for the smoke to quickly respond to the alarm. The practicality is poor and needs to be improved. Utility Model Content

One end of the spring 12 is fixedly connected to the limit block 9 so that the limit rod 10 can automatically recover.

[0024] Embodiment 2

[0025] See also Figure 1-3 5. A connecting frame 13 is fixedly installed on the surface of the shell 2, so that the shell 2 can rotate smoothly on the mounting plate 1. A connecting block 14 is fixedly installed on the surface of the shell 2, so that the connecting rod 15 can be installed. The connecting block 14 is slidably connected to the inside of the connecting rod 15, so that the connecting block 14 and the shell 2 can be clamped on the mounting plate 1. A pull head 16 is fixedly installed on one end of the connecting rod 15, which is convenient for pulling the connecting rod 15. A tension spring 17 is fixedly installed on the side of the pull head 16, so that the connecting rod 15 can automatically slide to the inside of the mounting plate 1.

[0026] Working principle: first, when the surface of the shell 2 needs to be cleaned, the handle 5 can be grasped and rotated, so that the handle 5 drives the rotating frame 3 to rotate on the surface of the shell 2. When the rotating frame 3 rotates, the brush block 6 can be driven to rotate, so that the smoke inlet on the shell 2 can be quickly cleaned, and the interior of the cover 7 is prevented from having a desiccant. The position of the brush block 6 is dried by the filter plate 8 to prevent the position of the brush block 6 from becoming moldy. When the desiccant needs to be replaced, the push plate 11 can be grasped and pulled to drive the limit rod 10 to slide inside the limit block 9. At the same time, the limit rod 10 slides inside the cover 7. When the limit rod 10 slides out from the inside of the cover 7, the cover 7 can be grasped and rotated. The interior can be replaced. After the replacement is completed, the cover 7 can be pressed to make the cover 7 stuck in the position of the rotating frame 3, and the push plate 11 and the limit rod 10 can be moved by the spring 12, so that the limit rod 10 slides to the inside of the cover 7 to jam the cover 7. When the interior needs to be maintained, the pull head 16 can be grabbed and pulled to make the pull head 16 drive the connecting rod 15 to slide. When the connecting rod 15 slides out from the inside of the mounting plate 1, the outer shell 2 can be rotated on the mounting plate 1 through the connecting frame 13, so as to maintain the interior. After the maintenance is completed, the outer shell 2 is rotated. When the connecting block 14 moves to the appropriate position, the connecting rod 15 can be driven by the tension spring 17 to slide from the inside of the connecting block 14 to the inside of the mounting plate 1.
