Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoke alarms, in particular to a smoke alarm for security engineering. Background Art
[0002] Smoke alarms prevent fires by monitoring the concentration of smoke, and use ion smoke sensors inside. Ion smoke sensors are technologically advanced, stable and reliable sensors with far superior performance to gas-sensitive resistor fire alarms. They are widely used in important fire prevention places such as homes, factories, office buildings, hospitals, schools, and museums.
[0003] The sensor of the ion alarm contains radioactive substances that can generate current. When smoke particles in the smoke enter the sensor, the current will be disturbed, causing the alarm to sound. Smoke alarms are suitable for places where there is a lot of smoke when a fire occurs, but there is no smoke under normal circumstances. However, they are not suitable for places where there is a lot of dust or water mist, places where steam and oil mist may be generated, and places where smoke is trapped under normal circumstances.
[0004] Security consists of three forms of protection: physical protection, human protection, and technical protection. Security engineering uses modern scientific and technological means to achieve security protection. Security engineering includes building intelligence (building intercom, etc.), video surveillance, access control and attendance, anti-theft alarm, parking lot management, smart home, computer room engineering, etc.
[0005] The patent document with publication number CN215495318U discloses a smoke alarm that is attached to a magnetic or iron surface inside a machine. Due to the effect of a strong magnet, the smoke alarm can be easily and conveniently attached to any magnetic or iron part, or directly placed in a small space. When damage occurs inside the machine and smoke is generated, the smoke enters the smoke alarm through an avoidance hole. After the smoke alarm component senses the smoke, it sounds an alarm to remind personnel to deal with it in time.
[0006] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0032] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0033] Embodiment 1:
[0034] This embodiment introduces a specific structure of a smoke alarm for security engineering. Figure 1-Figure 3 As shown, it comprises a smoke alarm body 1, a smoke alarm back cover 2 assembled on the bottom of the smoke alarm body 1, a magnet 3 received on the inner side of the bottom of the smoke alarm back cover 2 and an adhesive pad 5 located on the inner side of the magnet 3, a fixing frame ring 4 is arranged on the inner side of the magnet 3, the top of the fixing frame ring 4 is assembled and fixed to the inner wall of the smoke alarm back cover 2, and a back plate 6 is arranged on the inner side of the fixing frame ring 4;
[0035] like Figure 3 and Figure 4 As shown, the adhesive pad 5 includes foam 502, and the top and bottom surfaces of the foam 502 are processed with strong adhesive 501;
[0036] By adhering and fixing the surface of one strong adhesive sticker 501 to the surface of the back plate 6, the surface of another strong adhesive sticker 501 can be fixed to the target position when being adhered to the target position (cooperating with the magnet 3 to be adsorbed and fixed to the target position, it can be suitable for most installation environments);
[0037] Secondly, in order to fix the magnet 3 to the inside of the rear cover 2 of the smoke alarm, the fixing ring 4 is as follows: Figure 3 and Figure 4 As shown, the bottom inner wall of the magnet 3 is processed with a chamfer, and the bottom outer wall of the fixed frame ring 4 is formed with a limit ring 10. By making the limit ring 10 match the chamfer at the inner wall of the fixed frame ring 4, when the fixed frame ring 4 is assembled and fixed to the rear cover 2 of the smoke alarm, the magnet 3 can be encapsulated into the interior of the rear cover 2 of the smoke alarm with the help of the limit ring 10, so as to realize the storage of the magnet 3;
[0038] Furthermore, in order to facilitate the pasting of the adhesive pad 5 to the target position, the magnet 3 is separated from the non-metallic area. Figure 3As shown, the thickness of the adhesive pad 5 is greater than the thickness of the fixing frame ring 4. By making the strong adhesive 501 on one surface of the foam cotton 502 protrude from the inner side of the fixing frame ring 4 to the outside along the axial direction, the magnet 3 can be isolated from the target position when the adhesive pad 5 is attached and fixed to the target position.
[0039] Further, in order to facilitate the use of the back plate 6 to connect the fixing frame ring 4 to the rear cover 2 of the smoke alarm, as shown in FIG. Figure 5 As shown, a plurality of limiting bolts 7 are arranged inside the back plate 6. By threading one end of the plurality of limiting bolts 7 inside the rear cover 2 of the smoke alarm, the fixing frame ring 4 and the back plate 6 can be limited from being separated from the rear cover 2 of the smoke alarm.
[0040] By adopting the above technical solution:
[0041] The above design arranges a magnet 3 and an adhesive pad 5 inside the back cover 2 of the smoke alarm, and the magnet 3 is received inside the back cover 2 of the smoke alarm through a fixing ring 4 outside the adhesive pad 5. After a strong adhesive sticker 501 on the adhesive pad 5 is fixedly attached to the back plate 6 inside the fixing ring 4, another strong adhesive sticker 501 on the adhesive pad 5 can be attachedly attached to a target position (the magnet 3 is out of contact with the target position). At the same time, the magnet 3 is adsorbed on the target position, so that the foam cotton 502 is compressed after the strong adhesive sticker 501 on the adhesive pad 5 is attached to the target position. This design can adapt to most materials and facilitates fixing the smoke alarm body 1 and the back cover 2 of the smoke alarm to the target position to monitor the surrounding environment.
[0042] Embodiment 2:
[0043] Based on Example 1, this example introduces the specific structure of the back plate 6. The top surface of the back plate 6 is processed with a plurality of limit heads 9, and the outer parts of the plurality of limit bolts 7 are all sleeve-connected with springs 8.
[0044] By making the plurality of limit heads 9 interference fit inside the fixing frame ring 4, the back plate 6 can be restricted from rotating inside the fixing frame ring 4;
[0045] At the same time, by accommodating one end of the limiting bolt 7 inside the limiting head 9, when a strong adhesive sticker 501 on the adhesive pad 5 is attached to the surface of the back plate 6, it is possible to avoid partial protrusion of the adhesive pad 5;
[0046] Secondly, by supporting the spring 8 between the surface of one end of the stopper head 9 and the inner wall of the smoke alarm rear cover 2, after the stopper bolt 7 passes through the inside of the back plate 6 and is threadedly connected with the smoke alarm rear cover 2, the fixing frame ring 4 can be prevented from moving inside the smoke alarm rear cover 2;
[0047] Furthermore, in order to facilitate the control of the end surface of the adhesive pad 5 and the end surface of the magnet 3 being misaligned or flush, as Figure 3 , Figure 5 and Figure 6 As shown, an adjusting bolt 11 is provided inside the back plate 6, and a through hole is punched inside the adhesive pad 5. By movably connecting the adjusting bolt 11 to the inside of the through hole and threading one end of the adjusting bolt 11 to the inside of the smoke alarm back cover 2, the spring 8 between the inner wall of the smoke alarm back cover 2 and the limit head 9 can be compressed when adjusting the threaded connection between the adjusting bolt 11 and the smoke alarm back cover 2 to control the distance between the fixing frame ring 4 and the inner wall of the smoke alarm back cover 2. When the magnet 3 is fixed between the fixing frame ring 4 and the inner wall of the smoke alarm back cover 2, the distance between the adhesive pad 5 and the surface of the smoke alarm body 1 can be minimized.
[0048] By adopting the above technical solution:
[0049] The above design adjusts the threaded connection between one end of the adjusting bolt 11 and the rear cover 2 of the smoke alarm, and makes the back plate 6 drive the fixing frame ring 4 to approach the inner wall of the rear cover 2 of the smoke alarm. After the spring 8 is compressed by the limit head 9 on the back plate 6, one end of the adhesive pad 5 can be exposed outside the magnet 3 when the magnet 3 is fixed between the fixing frame ring 4 and the inner wall of the rear cover 2 of the smoke alarm.
[0050] At the same time, by adjusting the threaded connection between one end of the adjusting bolt 11 and the rear cover 2 of the smoke alarm, the fixing frame ring 4 moves with the limit head 9 and the back plate 6 to the side away from the inner wall of the rear cover 2 of the smoke alarm, so that the magnet 3 can be stored in the interior of the rear cover 2 of the smoke alarm, which is conducive to the magnet 3 sliding inside the rear cover 2 of the smoke alarm, so as to control the distance between one end of the magnet 3 and the surface of the smoke alarm body 1, and the distance between one end of the adhesive pad 5 and the surface of the smoke alarm body 1.
[0051] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
