[0002] Smoke alarm devices, also known as smoke detectors, prevent fires by monitoring the concentration of smoke. They use ionization smoke sensors, are stable and reliable in operation, and are widely used in various fire alarm systems.

[0003] In this regard, the existing technology patent announcement number: CN220730930U discloses a smoke alarm device, also known as a smoke detector, which prevents fires by monitoring the concentration of smoke. It uses an ionization smoke sensor inside, which is stable and reliable in operation and is widely used in various fire alarm systems.

[0004] However, in actual use, smoke alarm devices can only serve as alarms and cannot simultaneously ventilate the internal environment. In addition, existing smoke alarm devices have poor stability during installation. Therefore, improving and perfecting these issues is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide an alarm and ventilation linkage smoke alarm device to solve the problems mentioned in the background art, which can only play the role of alarm when working and cannot simultaneously perform ventilation operation on the internal environment. At the same time, the existing smoke alarm devices have poor stability during installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an alarm and ventilation linkage smoke alarm device, including a mounting frame, a fixing plate installed inside the mounting frame, a ventilation fan installed inside the fixing plate, a rotating column inserted into the inner side wall of the mounting frame, and a shielding plate installed on the outer surface of the rotating column.

[0007] A bidirectional motor is mounted on the back of a rotating column and is located inside a mounting frame. A rotating shaft is mounted on the output end of the back of the bidirectional motor. A stabilizing ring is fixedly connected to the outer surface of the rotating shaft. A connecting plate is mounted on the outer surface of the stabilizing ring. A striking block is mounted on the outer surface of the connecting plate.

[0008] Preferably, two sets of stabilizing rings and two sets of connecting plates are provided.

[0009] Preferably, a mounting plate and an adapter plate are installed sequentially from top to bottom on the right side surface of the mounting frame, and a base frame is installed at the lower end of the mounting plate.

[0010] Preferably, a metal alarm plate is installed at the lower end of the base frame, and the left side of the metal alarm plate abuts against the right side surface of the striking block.

[0011] Preferably, the adapter plate has an internal mounting groove, and the smoke alarm device body is installed inside the mounting groove.

[0012] Preferably, the inner wall of the adapter plate has a groove, and a miniature electric push rod is installed on the inner wall of the adapter plate, the miniature electric push rod being installed inside the adapter plate.

[0013] Preferably, a connecting post is installed on the right side of the miniature electric actuator, and an anti-slip pad is installed on the outer surface of the connecting post.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This alarm and ventilation-linked smoke alarm device, consisting of a fixed plate, ventilation fan, rotating column, baffle plate, bidirectional motor, rotating shaft, stabilizing ring, connecting plate, knocking block, mounting plate, base frame, and metal alarm plate, operates by first sensing smoke through the device itself. Upon sensing smoke, the smoke sensor electrically connects with the bidirectional motor, causing it to rotate. This rotation rotates the rotating column, which in turn rotates the baffle plate counter-clockwise, releasing it from its obstruction of the fixed plate and ventilation fan. The bidirectional motor then drives the rotating shaft, which in turn rotates the stabilizing ring and connecting plate. The connecting plate then causes the knocking block to contact the left side of the metal alarm plate, triggering an alarm. Simultaneously, the ventilation fan is activated, drawing air out of the room, thus achieving both ventilation and alarm functions.

[0016] 2. This alarm and ventilation-linked smoke alarm device, through the provided adapter plate, mounting slot, smoke alarm device body, groove, miniature electric push rod, connecting column, and anti-slip pad, allows for strong stability during installation. The smoke alarm device body contains a smoke sensor. It is then installed into the mounting slot, and the miniature electric push rod inside the groove is activated. This push rod moves the connecting column and anti-slip pad to the right, causing the anti-slip pad to press against the left side of the smoke alarm device body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 One embodiment provided by this utility model:

[0024] An alarm and ventilation-linked smoke alarm device is disclosed. The bidirectional motor 6, smoke alarm device body 16, and miniature electric push rod 18 used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be elaborated upon here. The device includes a mounting frame 1, with a fixing plate 2 installed inside the mounting frame 1. A ventilation fan 3 is installed inside the fixing plate 2. A rotating column 4 is inserted into the inner wall of the mounting frame 1, and a shielding plate 5 is installed on the outer surface of the rotating column 4. A mounting plate 11 and an adapter plate 14 are installed sequentially from top to bottom on the right side surface of the mounting frame 1. A base frame 12 is installed at the lower end of the mounting plate 11, and a metal alarm plate 13 is installed at the lower end of the base frame 12. The left side of the metal alarm plate 13 abuts against the right side surface of the striking block 10. An installation groove 15 is formed inside the adapter plate 14. The smoke alarm device body 16 is installed inside the mounting slot 15. The inner wall of the adapter plate 14 has a groove 17. A miniature electric push rod 18 is installed on the inner wall of the adapter plate 14. The miniature electric push rod 18 is installed inside the adapter plate 14. A connecting post 19 is installed on the right side of the miniature electric push rod 18. An anti-slip pad 20 is installed on the outer surface of the connecting post 19. When installing the smoke alarm device body 16, a smoke sensor is installed inside the smoke alarm device body 16. Then, the smoke alarm device body 16 is installed into the inside of the mounting slot 15. At the same time, the miniature electric push rod 18 inside the groove 17 is activated. Then, the miniature electric push rod 18 drives the connecting post 19 and the anti-slip pad 20 to move to the right. At this time, the anti-slip pad 20 will abut against the left side surface of the smoke alarm device body 16, so the smoke alarm device body 16 is more stable during installation.

[0025] A bidirectional motor 6 is mounted on the back of the rotating column 4 and is located inside the mounting frame 1. A rotating shaft 7 is mounted on the output end of the back of the bidirectional motor 6. A stabilizing ring 8 is fixedly connected to the outer surface of the rotating shaft 7. A connecting plate 9 is mounted on the outer surface of the stabilizing ring 8. A striking block 10 is mounted on the outer surface of the connecting plate 9. There are two sets of stabilizing rings 8 and two sets of connecting plates 9. A smoke sensor is installed inside the smoke alarm device body 16. Its working principle is the same as that in the prior art. At the same time, the smoke alarm device body 16 is electrically connected to the bidirectional motor 6 and the ventilation fan 3. When the smoke alarm device body 16 detects smoke, it activates the bidirectional motor 6 and the ventilation fan 3. Meanwhile, the metal alarm plate 13 is a metal plate. A sharp sound is emitted by striking the left side of the metal alarm plate 13 with the striking block 10, thereby completing the alarm operation. The smoke alarm device 16 senses smoke. When smoke is detected, the smoke sensor is electrically connected to the bidirectional motor 6, causing the bidirectional motor 6 to start rotating. This rotates the rotating column 4, which in turn drives the shielding plate 5 to rotate counterclockwise. This releases the shielding plate 5 from obstructing the fixed plate 2 and the ventilation fan 3. The bidirectional motor 6 then drives the rotating shaft 7 to rotate, which in turn drives the stabilizing ring 8 and the connecting plate 9 to rotate. This causes the connecting plate 9 to cause the striking block 10 to contact the left side of the metal alarm plate 13, causing the metal alarm plate 13 to emit a sound and automatically trigger an alarm. At the same time, the ventilation fan 3 is activated to extract air from the indoor environment, thus achieving both ventilation and alarm functions simultaneously.

[0026] Working Principle: When using this device, the operator first connects it to an external power source to provide power. The smoke alarm device body 16 first senses smoke. When smoke is detected, the smoke sensor is electrically connected to the bidirectional motor 6, causing the motor to rotate. This rotation rotates the rotating column 4, which in turn drives the baffle plate 5 to rotate counter-clockwise, releasing it from its obstruction of the fixed plate 2 and ventilation fan 3. The bidirectional motor 6 then drives the rotating shaft 7, which in turn drives the stabilizing ring 8 and connecting plate 9. This causes the connecting plate 9 to cause the striking block 10 to contact the left side of the metal alarm plate 13. The metal alarm panel 13 will emit a sound when the surface is exposed, thus automatically triggering an alarm. At the same time, the ventilation fan 3 will be activated to extract air from the indoor environment. When installing the smoke alarm device body 16, a smoke sensor is installed inside the smoke alarm device body 16. The smoke alarm device body 16 is then installed into the mounting groove 15. Simultaneously, the miniature electric push rod 18 inside the groove 17 is activated. The miniature electric push rod 18 then drives the connecting column 19 and the anti-slip pad 20 to move to the right. At this time, the anti-slip pad 20 will abut against the left side surface of the smoke alarm device body 16, thus ensuring strong stability when the smoke alarm device body 16 is installed. The above is the working principle of this utility model.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
