[0002] With the continuous advancement of urbanization, fire safety becomes the focus of people's attention. Common fire detectors are generally a single monitoring point, which can only alarm on site when a fire occurs, and the structure and function are relatively simple. Once there is no one on site, it may cause significant losses due to fire. The traditional smoke detector can form an automatic alarm monitoring network, but most of them use wired connection, which is prone to communication line installation and maintenance difficulties. The traditional smoke sensor cannot be used when power is off, and has no early warning function for fires occurring during power-off time. In addition, the stability and durability of these devices in high temperature environment still need to be improved. In order to solve this problem, the present application provides an intelligent smoke sensor. SUMMARY

[0003] The utility model discloses an intelligent smoke sensor, which solves the problems of insufficient stability of traditional smoke sensors in high temperature environment, complex installation and maintenance, etc. through multi-level fire monitoring and alarm, application of high-temperature-resistant materials, airflow optimization design, real-time safety information transmission and comprehensive solution.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0031] See also Figures 1-6 As shown, the present invention is an intelligent smoke detector comprising a top plate 1, a main board 2, a ceramic housing 3, and a bottom plate 4. The top plate 1 is mounted on the roof surface, and the main board 2 is mounted on the top plate 1 with screws. The lower end of the ceramic housing 3 is buckled onto the bottom plate 4. The top plate 1, ceramic housing 3, and bottom plate 4 are fixed together by a single-headed slender bolt 5. The main board 2 is provided with a smoke detection module 6, an NB-IOT communication module 7, and a buzzer 8. The NB-IOT communication module 7 is connected to a communication antenna 10 via a cable. The communication antenna 10 is vertically fixed to the lower surface of the main board 2 with double-sided tape. A tower filter 9 for smoke to pass through is installed in the middle of the bottom plate 4. When the smoke detection module 6 detects that the smoke concentration exceeds the limit, it outputs a smoke signal to the NB-IOT communication module 7, which is then transmitted to the upper-level management platform via the communication antenna 10. The upper-level management platform transmits the signal to the user's PC or mobile phone or the fire command center to realize remote alarm. At the same time, the NB-IOT communication module 7 is also used to periodically send safety information to the network nodes in the area, and conduct long-distance fire monitoring and alarm in real time.

[0032] The top plate 1 and the bottom plate 4 are both made of metal. The parts of the entire smoke sensor that are exposed to the heat during use are the ceramic shell 3, the bottom plate 4 and the tower filter 9. The overall temperature resistance is good and does not hinder the transmission of wireless signals. It can extend the operating time of the smoke sensor under the heat of a fire and ensure that the fire information is effectively transmitted to the outside.

[0033] The top plate 1 comprises a circular ring plate body 101. The circular ring plate body 101 is provided with four circular long holes 102 for mounting and fixing. The circular ring plate body 101 is provided with four threaded holes 103 for threadedly connecting with the single-head elongated bolt 5. Two internally threaded pipes 104 are fixedly arranged on the lower surface of the circular ring plate body 101 and are connected with the screws. The top plate 1 is installed on the roof surface by using air nails, expansion bolts and the like.

[0034] In order to improve the smoothness of the airflow in the smoke sensor and to ensure that the smoke can quickly enter the smoke sensor from the tower filter screen 9 when the fire is out of control, the ceramic shell 3 is in a cylindrical structure. Four air holes 31 are arranged on the outer wall of the top of the ceramic shell 3. In order to avoid the flame entering the smoke sensor from the four air holes 31 and damaging the inner wall structure when the fire is out of control, a metal isolation net is fixed on the inner side wall corresponding to the air hole 31.

[0035] The bottom plate 4 comprises a circular plate 41. The middle part of the circular plate 41 is provided with a conical cylinder part 42 which is arched upward. The tower filter screen 9 is installed on the inner wall of the conical cylinder part 42. The upper surface of the circular plate 41 is provided with a limiting baffle ring 43 which is matched with the lower end inner wall of the ceramic shell 3. Four first circular through holes 44 are arranged on the circular plate 41 and are matched with the single-head elongated bolt 5. The tower filter screen 9 comprises a first metal wire circular mesh 91, a second metal wire circular mesh 92 and a third metal wire circular mesh 93 which are arranged in parallel from bottom to top. The first metal wire circular mesh 91, the second metal wire circular mesh 92 and the third metal wire circular mesh 93 are connected into one body through a metal column 94 which is located at the center. The first metal wire circular mesh 91 is matched with the lower end of the conical cylinder part 42. The third metal wire circular mesh 93 is matched with the upper end of the conical cylinder part 42. The main plate 2 is further electrically connected with an indicating lamp 12. A second circular through hole 45 is arranged on the conical surface of the conical cylinder part 42 and is matched with the indicating lamp 12. When the smoke detection module 6 detects that the smoke density exceeds the limit, the control indicating lamp 12 is turned on to send an alarm signal. The combination of the buzzer 4 and the indicating lamp 12 realizes the sound and light alarm.

[0036] The conical cylinder part 42 of the bottom plate 4 is arched upward to facilitate the upward gathering of the smoke into the smoke sensor. The conical cylinder part 42 cooperates with the multi-layer metal wire circular mesh of the tower filter screen 9 to ensure the upward flow of the smoke and prevent the flame from entering the smoke sensor, thereby effectively ensuring the stable operation of the internal components of the smoke sensor under high temperature.

[0037] In order to avoid the smoke sensor from being unable to be used for a period of time when the whole building is powered off, a storage battery 11 is further electrically connected to the main plate 2. The storage battery 11 is installed above the main plate 2.
