DETAILED DESCRIPTION

[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figure 1-Figure 4 An embodiment of the utility model is a fire warning device, comprising a box body 1, a mounting plate 2 is arranged inside the box body 1, and an alarm module 3 for smoke alarm is arranged on the top of the mounting plate 2, and a smoke sensor 4 for sensing smoke is arranged at the bottom of the mounting plate 2, and a negative pressure component 5 for absorbing smoke is arranged at the bottom of the box body 1.

[0022] The specific problem targeted by this specific embodiment is to solve the problem that due to the slow floating speed of smoke, the probe takes a long time to sense the smoke, so that the fire warning can only be carried out after a period of time, thereby shortening the emergency rescue time. The utility model uses the setting of the negative pressure component 5. During the fire warning period, when a fire occurs, the smoke will float in the air under the influence of air flow. When the warning device is installed, the drive motor 54 is connected to the external power supply in advance, so that it drives the negative pressure fan 55 to rotate inside the smoking box 51. When the smoke passes through the bottom of the smoking box 51, it is affected by the suction of the negative pressure fan 55, and the smoke can be quickly sucked into the inside of the smoking box 51 and enter the inside of the box body 1 along the circular hole 521. The smoke sensor 4 can sense the existence of the smoke and then send out an alarm through the alarm module 3. Compared with the natural floating induction of the smoke, the active negative pressure absorption of the smoke can save a certain amount of smoke sensing time, thereby quickly taking emergency measures for the fire, avoiding the expansion of the fire, and thus improving the efficiency of the smoke warning.

[0023] The negative pressure assembly 5 includes a smoking box 51 arranged at the bottom of the box body 1, and a fixed plate 52 is fixedly connected to the top of the smoking box 51, and a motor slot 53 is opened in the middle of the surface of the fixed plate 52, and a driving motor 54 is fixedly connected inside the motor slot 53, and a negative pressure fan 55 for absorbing smoke is fixedly connected to the output end of the driving motor 54. In the present specific embodiment, a plurality of circular holes 521 for penetrating smoke are opened in a circular array on the surface of the fixed plate 52 and on one side of the motor slot 53, and a protective cover 511 for protection is set at the bottom of the smoking box 51. During the fire warning period, when a fire occurs, the smoke will float in the air due to the influence of air flow. When installing the warning device, the drive motor 54 is connected to an external power supply in advance so that it drives the negative pressure fan 55 to rotate inside the smoking box 51. When the smoke passes through the bottom of the smoking box 51, it is affected by the suction of the negative pressure fan 55 and can be quickly sucked into the smoking box 51 and enter the box body 1 through the circular hole 521. The smoke sensor 4 can sense the presence of smoke and then sound an alarm through the alarm module 3. Compared with the natural floating induction of smoke, the active negative pressure absorption of smoke can save a certain amount of smoke sensing time, thereby quickly taking emergency measures to the fire and avoiding the expansion of the fire, thereby improving the efficiency of the smoke warning.

[0024] In this specific embodiment, the outer surface of the smoking box 51 is provided with a plurality of long grooves for the entry of smoke, and the long grooves are distributed in a rectangular array, a box cover 6 is provided on the top of the box body 1, and a connecting plate 7 is provided on the top of the box cover 6, and a plurality of connecting plates 8 are provided on the side of the connecting plate 7, and a threaded hole is provided on the surface of the connecting plate 8, and a threaded nail 9 for installation and connection is provided inside the threaded hole, and the number of the threaded nails 9 is four.
