DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-6, An emergency drill alarm device provided by the utility model includes: a star-shaped shell 1, and further includes: round openings 2 formed on the outer walls of the upper and lower sides of the star-shaped shell 1, lower through pipes 3 fixed to the outer wall ports of the star-shaped shell 1 at equidistant intervals, and an air extraction assembly 4 installed at the top of the star-shaped shell 1. Suspension assemblies 5 are installed at the four corners of the outer part of the top of the air extraction assembly 4, and an alarm assembly 6 is installed on the outer wall of the bottom of the star-shaped shell 1.

[0019] In a specific application scenario, the device can be fixed on the ceiling of the factory building through the suspension assembly 5, and the installation height of the device can also be adjusted through the suspension assembly 5 to facilitate adaptation to the height of the factory building. The air extraction assembly 4 provided can draw the gas around the bottom of the device into the star-shaped shell 1 through the lower through pipes 3. If there is smoke generated by a small fire source nearby, it will also be drawn into the star-shaped shell 1. When the air flow is drawn into the star-shaped shell 1, it will pass through the alarm assembly 6. When the alarm assembly 6 detects the smoke, it will immediately give an alarm, with timely alarm and avoiding missing the best alarm time.

[0020] In a preferred embodiment, the air extraction assembly 4 includes an air extraction hood 401, an air extraction pipe 402 connected to the top end of the air extraction hood 401, and an air extraction fan 403 installed on the inner wall of the air extraction pipe 402.

[0021] In a specific application scenario, the blades of the air extraction fan 403 rotate to generate an air flow, blowing the air inside the air extraction hood 401 and the star-shaped shell 1 outwards, and at the same time forming a negative pressure to suck the air around the lower part of the device into the star-shaped shell 1 through the lower through pipes 3.

[0022] In a preferred embodiment, the suspension assembly 5 includes a connection seat 501, a threaded rod 502 fixed to the top of the connection seat 501, an internally threaded pipe 503 screwed onto the outer wall of the threaded rod 502, a connection frame 504 fixed to the outer wall of the internally threaded pipe 503, a fixing plate 505 fixed to the top of the connection frame 504, and fixing holes 506 formed at both ends of the outer wall of the top of the fixing plate 505.

[0023] In a specific application scenario, by rotating the internally threaded pipe 503, the internally threaded pipe 503 can move on the threaded rod 502, thereby adjusting the overall height of the suspension assembly 5. After adjustment, it can be fixed to the ceiling of the factory building by passing a bolt through the fixing hole 506.

[0024] In a preferred embodiment, the alarm assembly 6 includes a chassis 601, a mesh ring 602 installed on the outer wall of the top of the chassis 601, smoke sensors 603 installed on the outer wall of the mesh ring 602 at equidistant intervals, an alarm 604 installed on the outer wall of the bottom of the chassis 601, and a controller 605.

[0025] In a specific application scenario, when the air flow is pumped into the star-shaped housing 1, it will pass through the smoke sensor 603. When the smoke sensor 603 detects smoke in the air flow, it will transmit a signal to the controller 605, and the controller 605 will automatically activate the alarm 604 to issue an alarm.

[0026] In a preferred embodiment, the air extraction hood 401 and the outer wall of the chassis 601 are both provided with arc-shaped grooves distributed at equal distances, and the arc-shaped grooves correspond to the arc-shaped part of the star-shaped housing 1.

[0027] In a specific application scenario, the air extraction hood 401, the chassis 601 and the star-shaped housing 1 have higher integrity after installation.

[0028] In a preferred embodiment, both the smoke sensor 603 and the alarm 604 are connected to the controller 605 through signal lines, and both the controller 605 and the exhaust fan 403 are connected to an external power source through power lines.

[0029] In a specific application scenario, the controller 605 can control the smoke sensor 603 and the alarm 604.

[0030] Working principle: It can be fixed on the factory ceiling through bolts passing through the fixing holes 506. Before installation, the internally threaded tube 503 can be rotated to move the internally threaded tube 503 on the threaded rod 502, facilitating the adjustment of the installation height of the device. The exhaust fan 403 can be used to generate an air flow by the rotation of the blades, blowing the air inside the air extraction hood 401 and the star-shaped housing 1 outwards, and at the same time forming a negative pressure to suck the air around the lower part of the star-shaped housing 1 through the lower connecting pipe 3. If there is smoke generated by a small fire source nearby, it will also be sucked into the star-shaped housing 1. The air flow sucked into the star-shaped housing 1 will pass through the smoke sensor 603. When the smoke sensor 603 detects smoke in the air flow, it will transmit a signal to the controller 605, and the controller 605 will automatically activate the alarm 604 to issue an alarm, with timely alarm and avoiding missing the best alarm time.
