[0037] As Figure 3As shown, the second connecting rod 900 is arranged in the interior of the first connecting rod 600, one end of the second connecting rod 900 is in sliding connection with the first connecting rod 600, and the other end of the second connecting rod 900 is fixed on the outer shell 100.

[0038] Specifically, one end of the second connecting rod 900 is fixedly connected with the outer shell 100, and the other end of the second connecting rod 900 extends to the interior of the first connecting rod 600 and is in sliding connection with the first connecting rod 600.

[0039] Further, the second connecting rod 900 is arranged in a polygonal column structure, for example, a 6-sided structure. The interior of the first connecting rod 600 is also arranged in a corresponding structure, so that the second connecting rod 900 limits the first connecting rod 600, preventing the first connecting rod 600 from rotating, and further preventing the storage bin from rotating, avoiding the storage bin from rotating with the cylinder 400.

[0040] As shown, Figure 2 the drive assembly further includes a drive motor 110, and a drive gear 111 is further arranged on the cylinder 400, which is used to cooperate with the drive motor 110 to drive the cylinder 400 to rotate.

[0041] As shown, Figure 2 a protrusion is arranged above the cylinder 400, the drive gear 111 is arranged on the inner wall of the protrusion, the drive motor 110 is arranged in the interior of the connecting portion 119, the output shaft of the drive motor 110 extends from the interior of the connecting portion 119 to the interior of the outer shell 100, a driving gear 112 is arranged at the end of the output shaft of the drive motor 110, and the driving gear 112 is in meshing connection with the drive gear 111, which is used to drive the cylinder 400 to rotate by the drive motor 110.

[0042] Specifically, the drive gear 111 is arranged on the inner wall of the protrusion, and the second connecting rod 900 passes through the protrusion to be connected with the outer shell 100.

[0043] An installation cavity is arranged in the interior of the connecting portion 119, and a control module and a power module are arranged in the interior of the installation cavity; wherein the control module is used to receive the signal of the fire monitoring sensor, and the drive motor 110 is controlled to rotate by the control module, and the alarm lamp 200 and the loudspeaker 300 are controlled to issue an alarm.

[0044] Further, the control module adopts an existing device, for example, a single-chip microcomputer control chip with wireless transmission function.

[0045] Further, the power module is used to provide power supply for the control module, the drive motor 110, and the alarm lamp 200 and the loudspeaker 300, so as to ensure that the device can work normally when a fire occurs.

[0046] The inner wall of the outer shell 100 is provided with a mounting groove 113, and the cylinder body 400 is rotationally arranged in the mounting groove 113.

[0047] Specifically, by arranging the mounting groove 113, the cylinder body 400 is rotationally arranged in the mounting groove 113, and the mounting groove 113 limits the cylinder body 400, so that the cylinder body 400 can only rotate in the mounting groove 113 and cannot move, thereby ensuring the normal operation of the device.

[0048] As shown in Figure 2 , the bottom of the outer shell 100 is provided with a sealing film 114, and the sealing film 114 is used to seal the outer shell 100.

The extension cone 116 is detachably connected with the mounting disc 115.

[0051] Further, the extension cone 116 of the extension cone 116 is arranged downward, and when the pushing assembly pushes the storage bin to move downward, the extension cone 116 of the extension cone 116 will pierce the sealing film 114, so that the storage bin can be smoothly discharged.

[0052] Further, the extension cone 116 is detachably connected with the mounting disc 115 (for example, by bolt connection), and when a fire occurs, the extension cone 116 can be detached from the mounting disc 115 and used as a survival tool, thereby further improving the practicality of the device.

[0053] As shown in Figure 5 , the middle of the bin cylinder 800 is provided with a storage space 117, and the storage space 117 is used to store emergency supplies.

[0054] Specifically, the emergency supplies that can be placed in the storage space 117 include a strong light flashlight, a first-aid kit, an escape rope, a small fire extinguisher, a fireproof escape blanket, and a filter type fire self-rescue respirator; one or more can be placed according to actual conditions.

[0055] As shown in Figure 5 , a chute 118 is arranged in the bin cylinder 800, and the chute 118 is used to install a sealing plate 120. The sealing plate 120 is used to fix the emergency supplies in the bin cylinder 800.

[0056] Further, the emergency supplies are fixed by the sealing plate 120, so as to prevent the emergency supplies from falling out of the inside of the storage cylinder 800 when the storage cylinder 800 slides downward.

[0057] Further, in order to ensure that the cylinder body 400 does not rotate, the storage bin is not affected by gravity and does not fall downward, a groove is arranged at the upper end of the arc-shaped guide rail 500, and the groove is communicated with the arc-shaped guide rail 500.

[0058] When the alarm device does not act, the guide column 700 is arranged in the groove, the guide column 700 is limited by the groove, and the falling of the storage bin is prevented. When the fire occurs, the alarm device acts, the driving motor 110 rotates to drive the cylinder body 400 to rotate, the guide column 700 is extruded out of the groove, and the guide column 700 enters the arc-shaped guide rail 500, so that the guide column 700 is driven to move up and down by the arc-shaped guide rail 500.

[0059] The end of the storage cylinder 800 is rotationally connected with the first connecting rod 600, so that the storage cylinder 800 can be flexibly unfolded to expose the emergency supplies. The design ensures that the emergency supplies are safely stored in the storage bin, and the emergency supplies can be quickly and effectively presented to the user when needed, and the emergency supplies are convenient to take.

[0060] In the application, the alarm function is combined with the emergency supplies storage function, and the pushing assembly and the storage bin are arranged in the inside of the shell body 100, so that the overall structure is compact, a large amount of space is not occupied, the device is suitable for being installed in various places, such as corridors and rooms in buildings, the space utilization rate is improved, and the installation and maintenance of the device are facilitated.

[0061] The working principle of the application is as follows: when the fire occurs, the fire monitoring sensor signal is transmitted to the control module (such as a single-chip microcomputer control chip with wireless transmission function), the control module controls the alarm lamp 200 and the loudspeaker 300 to emit sound and light alarms on one hand, so as to attract the attention of people, and controls the driving motor 110 to rotate on the other hand.

[0062] The driving gear 112 at the output shaft end of the driving motor 110 is engaged with the driving teeth 111 on the convex inner wall of the cylinder body 400, so as to drive the cylinder body 400 to rotate. The arc-shaped guide rail 500 on the inner wall of the cylinder body 400 cooperates with the storage bin guide column 700, the guide column 700 slides in the arc-shaped guide rail 500, and the storage bin is driven to move downward. Since the second connecting rod 900 (a polygonal column structure, which cooperates with the corresponding structure in the inside of the first connecting rod 600 to limit) in the first connecting rod 600 is fixed to the shell body 100 and prevents the first connecting rod 600 from rotating, the stable downward movement of the storage bin is ensured.

[0063] The telescopic cone 116 on the end mounting disc 115 pierces the bottom sealing film 114 of the outer shell 100 during the descending process of the storage bin. When the storage bin extends outside the outer shell 100, the end of the bin cylinder 800 is rotationally connected with the first connecting rod 600 to unfold it, so as to expose the emergency supplies (such as a strong light flashlight, a first-aid kit, etc.) in the storage space 117 of the bin cylinder 800. The sealing plate 120 in the bin cylinder 800 can prevent the emergency supplies from falling out during the descending process. The whole device realizes fire alarm and rapid use of emergency supplies, and improves the ability of people to cope with fire.

[0064] In summary, the device in the application can not only alarm in time, but also provide emergency supplies, so as to enhance the safety of the place from the aspects of early warning and self-rescue in the initial stage of fire, and reduce the loss and harm caused by fire.
