Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0031] Embodiment: Refer to Figures 1-5 A smoke alarm based on the Internet of Things as shown, including a fixed cylinder 1 and a main chassis 4. An extension board 2 is fixedly sleeved on the circumferential side of the bottom of the fixed cylinder 1, and a set of spring buckles 3 are fixed on the circumferential side of the fixed cylinder 1;

[0032] The main chassis 4 is fixed inside the fixed cylinder 1. A number of permanent magnets 14 are fixedly embedded at the top of the main chassis 4. At the positions corresponding to the permanent magnets 14 on the inner top surface of the fixed cylinder 1, a number of end plates 11 are fixed. The end plates 11 are made of ferromagnetic materials, and the positions of the end plates 11 correspond to those of the permanent magnets 14. The end plates 11 can be adsorbed and fixed by the permanent magnets 14. A wire harness chamber is formed between the top of the main chassis 4 and the inner top surface of the fixed cylinder 1. External wires pass through the fixed cylinder 1 and are electrically connected to the connectors at the top of the main chassis 4. The plug connectors of the wiring terminals can be retained in the wire harness chamber, realizing the storage and arrangement of the wires, facilitating wiring and cabling, enabling the wires to be safely hidden, and also improving the aesthetics of the installation of the smoke alarm.

[0033] A smoke sensor 5, a buzzer 6, a warning light 16, and a switch button 7 are provided at the bottom of the main chassis 4.

[0034] When installing this smoke alarm, it is necessary to reserve a slot hole on the ceiling that is adapted to the fixing cylinder 1. Insert the fixing cylinder 1 into the slot hole so that the ceiling at the edge of the reserved slot hole is clamped between the spring buckle 3 and the extension plate 2 to achieve the fixed installation of the fixing cylinder 1. Subsequently, send the main chassis 4 with the wiring connected into the interior of the fixing cylinder 1. Through the adsorption and fixation of the permanent magnet 14 on the end plate 11, the main chassis 4 and the end plate 11 are fixed together. The top surface of the main chassis 4 does not contact the inner top surface of the fixing cylinder 1, and there is a certain distance between the end plate 11 and the inner top surface of the fixing cylinder 1. The existence of this distance forms a wiring harness chamber.

[0035] To facilitate the entry and exit of external wires into and out of the fixing cylinder 1, in this embodiment, a wire passing hole 8 is opened at the top of the fixing cylinder 1, and a wiring groove 15 is provided at the top of the main chassis 4. The external wire passes through the wire passing hole 8 and enters the interior of the fixing cylinder 1. The wiring end of the wire is inserted and fixed to the wiring groove 15, and thus the wiring operation of the main chassis 4 can be completed.

[0036] To ensure that the end face of the end plate 11 and the end face of the permanent magnet 14 can be completely fitted and fixed together, ensure that the permanent magnet 14 generates sufficient adsorption force on the end plate 11, and improve the high stability of the installation of the main chassis 4. In this embodiment, a number of docking grooves 13 are opened on the upper surface of the main chassis 4. The number of docking grooves 13 is distributed in a circular array on the upper surface of the main chassis 4. The permanent magnet 14 is fixed at the bottom of the docking groove 13, and the horizontal height of the upper surface of the permanent magnet 14 is lower than the horizontal height of the notch of the docking groove 13. The bottom of the end plate 11 enters the docking groove 13 and is adsorbed and fixed to the permanent magnet 14. The multiple end plates 11 and docking grooves 13 arranged in a circular array can enable the main chassis 4 to receive a uniformly upward pulling force, improve the stability of the main chassis 4 during fixation, and at the same time play a role in rapid positioning.

[0037] To ensure that the smoke sensors 5 on the main chassis 4 of different models can extend from the inside of the fixing cylinder 1, in this embodiment, a number of threaded holes 9 are opened at the top of the fixing cylinder 1, and a bolt column 10 is fixed on the upper surface of the end plate 11. The bolt column 10 passes through the threaded hole 9 and is threadedly connected to the threaded hole 9. A ribbed groove 12 is opened on the lower surface of the end plate 11. The ribbed groove 12 is a hexagonal prism groove. The end plate 11 can be rotated through the ribbed groove 12, thereby driving the bolt column 10 to rotate inside the threaded hole 9, and the horizontal height of the end plate 11 can be adjusted. The capacity of the wiring harness chamber formed between the main chassis 4 and the fixing cylinder 1 is changed. While facilitating the storage of the wiring harness, the horizontal installation height of the main chassis 4 of different models can be adjusted to ensure that the smoke sensors 5 can extend from the inside of the fixing cylinder 1, ensuring the agility of the smoke sensors 5 for smoke detection, being easy to adjust, and having strong applicability.

[0038] Further, in this embodiment, the main chassis 4 includes a control module, a communication module, and a power module. The switch button 7 is connected to the power module through a circuit. The power module is electrically connected to the output end of the external power cord, and the power module supplies power to the entire main chassis 4. The communication module is electrically connected to the control module. The smoke sensor 5, the buzzer 6, and the warning light 16 are all electrically connected to the control module. The output end of the communication module is electrically connected to the external main control module through a data transmission line. By pressing the switch button 7, the opening and closing of the power module can be controlled to realize the control of the power supply of the device. After the smoke sensor 5 detects smoke, it will transmit the detection signal to the control module. After receiving the signal, the control module controls the buzzer 6 and the warning light 16 to start. The control module transmits the smoke detection signal to the communication module, and the communication module then transmits the received signal to the external main control module through the data transmission line, realizing the Internet of Things of the smoke alarm and improving the accuracy and response speed of the fire alarm.

[0039] Specifically, the power module can adopt a built-in battery configured inside the smoke alarm or supply power to the smoke alarm by connecting a power supply. The control module and the communication module can adopt the corresponding modules on the existing Internet of Things smoke alarms in the prior art. The main control module can adopt the main control module of the Internet of Things devices used in households in the prior art or the main control module matching the aforementioned existing Internet of Things smoke alarms. The above modules all adopt products in the prior art, and those skilled in the art can obtain them through commercial means and complete their settings through the prior art.
