[0003] Through prior art search, the following known technical solutions exist: Prior Art 1: A smoke detector for building fire safety Application number: CN202221253048.X, application date: 2022.08.30, publication (announcement) date: 2022.08.30.

[0004] Prior art 1 belongs to the technical field of fire-fighting equipment, and specifically relates to a smoke detector for building fire safety, including a smoke detector shell, a mounting base connected to the top of the smoke detector shell, the mounting base having two downward-opening limit grooves, the limit grooves being located on opposite sides of the mounting base, the side walls of the limit grooves being provided with limit card slots connected thereto, a mounting shell connected to the top of the smoke detector shell, the mounting shell being externally connected to a retractable shell that can be plugged into the limit card slots, and also including a power component for driving the retractable shell to achieve retraction; the smoke detector for building fire safety disclosed in prior art 1 has the effect of being easy to disassemble and assemble and convenient to use.

[0005] However, the smoke detector housing and the power assembly in the prior art 1 cooperate with each other, making it difficult for the smoke detector to inhale when used indoors. As a result, when a fire occurs indoors, the smoke in the air cannot be monitored in time, and the monitoring and feedback immediacy are not ideal.

[0006] Through the above search, it was found that the above technical solutions do not affect the novelty of the present invention. Summary of the Invention

[0007] In order to avoid the above-mentioned deficiencies in the prior art, the present invention provides a smoke detector for building fire safety.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] The circumferential surface of the smoke detector body 1 is provided with an air hole 47 , and the function of the air hole 47 is to discharge the purified gas.

[0022] Activated carbon 48 is fixedly connected to the inner wall of the smoke detector body 1. The function of the activated carbon 48 is to remove harmful gases in the smoke.

[0023] The number of the ventilation holes 47 is set to be several, and they are arranged in a circular array along the circumference of the smoke detector body 1 , so that the ventilation effect is improved by the multiple ventilation holes 47 .

[0024] A cleaning mechanism 5 is provided inside the smoke detector body 1, and the cleaning mechanism 5 includes a threaded sleeve 51. The side of the threaded sleeve 51 is threadedly connected to the circumferential surface of the threaded rod 42, and the side of the threaded sleeve 51 is fixedly connected to a connecting rod 52. The end of the connecting rod 52 away from the side of the threaded sleeve 51 is fixedly connected to a cleaning scraper 53. An inlay groove 54 is provided at the bottom of the smoke detector body 1, and a collection box 55 is slidably connected inside the inlay groove 54. A spring telescopic rod 56 is fixedly connected to the side of the collection box 55. A locking hole 57 is provided on the circumferential surface of the smoke detector body 1. The function of the cleaning mechanism 5 is to clean the micropores on the surface of the activated carbon 48 to prevent the micropores on the surface of the activated carbon 48 from being blocked.

[0025] The circumferential surface of the threaded rod 42 is fixedly penetrated by a limit plate 58 , and the function of the limit plate 58 is to limit the displacement distance of the threaded sleeve 51 .

[0026] The side of the cleaning scraper 53 is in contact with the circumferential surface of the activated carbon 48, and the top of the collecting box 55 is located directly below the cleaning scraper 53.

[0027] During specific use, after the smoke detector body 1 is installed, the staff starts the micro motor 41, and the output end of the micro motor 41 rotates counterclockwise. The rotation of the micro motor 41 drives the rotating shaft 43 to rotate through the threaded rod 42, and the rotation of the rotating shaft 43 drives the suction body 44 to rotate counterclockwise, thereby causing the fan blades inside the suction body 44 to rotate to generate suction. When smoke or fire appears in the room, the suction body 44 increases the detection speed of the surrounding air, and the air enters the smoke detector body 1 through the air inlet 45 and the air inlet channel 46, and an alarm is sounded through the smoke detection element 2, turning on the alarm light 3, and the absorbed smoke removes harmful gases through the activated carbon 48 and is discharged through the air vent 47.

The cleaned impurities fall into the collection box 55. When the staff conducts regular inspections, they press the spring telescopic rod 56 to make it leave the locking hole 57 and disassemble the collection box 55.
