[0021] The disassembly assembly comprises: a disassembly plate 2 arranged on the top of the smoke detector housing 101, a connecting ring 201 connected to the top of the disassembly plate 2 in a circular ring structure, a connecting block 202 connected to the bottom of the mounting plate 1, a connecting groove 203 in a circular ring structure provided at the bottom of the connecting block 202, and the connecting ring 201 is threadedly connected to the connecting groove 203. When the smoke detector housing 101 needs to be installed on a wall, first observe whether a hole can be opened on the wall. If a hole can be opened, the mounting hole 103 can be aligned with the hole, and then the expansion bolt can be inserted into the mounting hole 103 and the hole, so as to fix the mounting plate 1 on the wall. If a hole cannot be opened on the wall, the mounting plate 1 can be glued to the wall. When installing the smoke detector housing 101, the disassembly plate 2 is installed on the top of the smoke detector housing 101, and then the connecting ring 201 on one side of the disassembly plate 2 is inserted into the connecting groove 203, and then the smoke detector housing 101 is rotated to drive the connecting ring 201 to rotate, so that the connecting ring 201 is threadedly connected with the connecting groove 203, thereby fixing the smoke detector housing 101 on one side of the outer end of the connecting block 202. When the smoke detector housing 101 needs to be disassembled, the smoke detector housing 101 is rotated to drive the connecting ring 201 to rotate until the connecting ring 201 is rotated out of the connecting groove 203, and the smoke detector housing 101 and the disassembly plate 2 can be separated from the connecting block 202.

[0022] Wherein, both sides of the top of the smoke detector housing 101 are connected with plug blocks 3, both sides of the bottom of the disassembly plate 2 are provided with slots 301 slidably connected with the plug blocks 3, one side of the inner wall of the slot 301 is inclined, and one side of the outer end of the plug block 3 is provided with a movable slot 302, and both sides of the outer end of the disassembly plate 2 are provided with a card slot 303, and the two card slots 303 are respectively connected with the two slots 301. When the disassembly plate 2 and the smoke detector housing 101 need to be installed, the two plug blocks 3 are respectively aligned with the two slots 301, and then the plug block 3 is inserted into the slot 301. The side is inclined and the side of the inner wall of the slot 301 is inclined, so when the block 4 slides into the slot 301, the block 4 will be squeezed by the slot 301 to move into the movable slot 302 to compress the spring 402 until the plug 3 is completely inserted into the slot 301. At this time, the movable slot 302 is relative to the slot 303, and the rebound force of the spring 402 can push the block 4 to move in the direction of the slot 303 until one end of the block 4 is located in the slot 303, thereby engaging the plug 3 in the slot 301 and fixing the disassembly plate 2 on the top of the smoke detector housing 101.

[0023] Among them, a block 4 slidably connected to the slot 303 is arranged inside the movable slot 302, one side of the top of the block 4 is inclined, one end of the block 4 is connected to a limiting rod, one side of the inner wall of the movable slot 302 is provided with a limiting hole 401 slidably connected to the limiting rod, a spring 402 is arranged on the outside of the limiting rod, a push block 403 is arranged inside the slot 303, and one side of the outer end of the push block 403 is connected to a pressing plate 404. When it is necessary to disassemble the disassembly plate 2, the pressing plates 404 on both sides of the outer end of the disassembly plate 2 are pressed, so that the pressing plates 404 drive the push block 403 to move toward the block 4 until the push block 403 completely pushes one end of the block 4 located in the slot 303 out of the slot 303. At this time, the plug block 3 can be slid out of the slot 301 to disassemble the disassembly plate 2.

[0024] Among them, the monitoring component includes: a battery frame 5 arranged inside the smoke detector housing 101, a power sensor 501 installed on one side of the outer end of the battery frame 5, a voice announcer 502 installed on one side of the inner wall of the smoke detector housing 101, and multiple sound-permeable openings 503 opened on both sides of the bottom of the smoke detector housing 101. When the device is used, the power sensor 501, the voice announcer 502, the control button 703, the smoke sensor 601 and the buzzer 7 are powered by the battery 102, wherein the power sensor 501 can monitor the power of the battery 102. When the power of the battery 102 is too low, the power sensor 501 outputs a signal to the voice announcer 502, and the voice announcer 502 broadcasts a voice reminder that the power is too low and the battery 102 needs to be replaced.

[0025] The model of the power sensor 501 is KINAX WT707-143D. The working principle of the power sensor 501 is that it can sense the information of the measured power, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control.

[0026] Among them, support rods 6 are connected to both sides of the outer end of the battery frame 5, and one end of the two support rods 6 is respectively connected to the two sides of the inner wall of the smoke detector shell 101, and a smoke sensor 601 is installed at the bottom of the battery frame 5, wherein the support rods 6 are used to fix the battery frame 5 inside the smoke detector shell 101, and the battery 102 is located in the battery frame 5. When the battery 102 needs to be replaced, the smoke detector shell 101 is disassembled from one side of the outer end of the mounting plate 1, and then the disassembly plate 2 is separated from the smoke detector shell 101, and the battery 102 can be replaced.

[0027] The signal of smoke sensor 601 is M75118. The working principle of smoke sensor 601 is to detect smoke by detecting the influence of smoke particles on the current of the ionization chamber. When smoke particles enter the ionization chamber, they will affect the current signal in the ionization chamber. The principle of the ionization chamber method is that the positive and negative ions generated by ionization move to the positive and negative electrodes respectively under the action of the electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once smoke enters, it interferes with the normal movement of charged particles, the current and voltage will change, destroying the balance between the inner and outer ionization chambers, thereby triggering an alarm.

[0028] Among them, a buzzer 7 is installed on one side of the inner wall of the smoke detector housing 101, a bottom plate 701 is arranged at the bottom of the smoke detector housing 101, a plurality of vertical rods are connected between the top of the bottom plate 701 and the smoke detector housing 101, a filter screen 702 is installed between two adjacent vertical rods, a control button 703 is installed on one side of the inner wall of the bottom plate 701, a through hole is opened at the bottom of the bottom plate 701, and a pressing block 704 is arranged on one side of the inner wall of the through hole. When the device is used, the smoke sensor 601 is used to monitor whether smoke appears in the space. When the smoke sensor 601 detects smoke, the smoke sensor 601 outputs a signal to the buzzer 7, and an alarm sound is issued through the buzzer 7 to remind that a fire has occurred. The filter screen 702 is used for dust prevention to prevent dust from affecting the use of the smoke sensor 601, and the control button 703 can control the start and stop of the buzzer 7 and the voice announcer 502. The pressing block is made of flexible plastic, so the user can use the control button 703 by pressing the pressing block 704.

[0029] The model of buzzer 7 is ESZ-11-A. The working principle of buzzer 7 is that piezoelectric buzzers use the piezoelectric effect to generate sound. They usually contain a piezoelectric ceramic crystal. When an external voltage is applied to the piezoelectric crystal, the crystal generates mechanical vibrations, thereby generating sound. This vibration is amplified by the resonance cavity of the buzzer. Electromagnetic buzzers use the electromagnetic effect to generate sound. They contain a coil and an iron vibrating plate. When an alternating current passes through the coil, the coil generates a magnetic field, which attracts the iron vibrating plate to vibrate. The vibration of the vibrating plate forms periodic compression fluctuations in the air, thereby generating sound.
