It not only has high detection sensitivity and wide detection range, but also works very reliably, generally without false alarms, and can work stably in the temperature range of -15 to +60 degrees. It is incomparable to the alarm circuits composed of infrared rays, ultrasonic waves, pyroelectric elements and conventional microwave circuits in the past. It is the best product for security prevention and automatic monitoring. A protective slider 11 is plugged into the lower surface of the protective cabinet 2. A protective plate 12 is plugged into one side of the protective cabinet 2. A fireplace 13 is plugged into the upper surface of the protective slider 11.The upper surface of the fireplace 13 is plugged with a sprinkler head 14, and one side of the fireplace 13 is plugged with a smoke exhaust component 15. The smoke exhaust component 15 includes a smoke exhaust pipe 1501, a smoke exhaust base 1502, a second alarm 1503, a fan pipe 1504, and a smoke exhaust fan 1505. The surface of the smoke exhaust pipe 1501 is plugged with the smoke exhaust base 1502, the upper surface of the smoke exhaust base 1502 is plugged with the second alarm 1503, one side of the smoke exhaust pipe 1501 is plugged with the fan pipe 1504, and one end of the fan pipe 1504 is sleeved with the smoke exhaust fan 1505.

The smoke exhaust hole of the connection seat fixes the smoke exhaust pipe 1501, and the fan hole of the connection seat fixes the fan pipe 1504. The second alarm 1503 is a smoke sensor alarm. In fact, the smoke sensor alarm is another name for a smoke sensor or a smoke detector. The smoke sensor alarm realizes fire prevention by monitoring the concentration of smoke. It adopts an ionization type smoke sensor inside. The ionization type smoke sensor is a sensor with advanced technology and stable and reliable operation. It is widely used in various fire alarm systems and has far better performance than the gas-sensitive resistor type fire alarm. The top of one side of the protection plate 12 is plugged with a flap motor 16. One end of the flap motor 16 is sleeved with an alarm bell 17. There is a flap shaft on one side of the alarm bell 17. The flap shaft of the alarm bell 17 is adapted to the flap motor 16. The material of the alarm bell 17 is stainless steel. The bottom of one side of the protection plate 12 is plugged with a moving motor 18. One end of the moving motor 18 is sleeved with a moving lead screw 19. A moving slide rail is provided at the bottom inside the protection cabinet 2. The moving slide rail of the protection cabinet 2 fixes the moving lead screw 19. A lead screw hole is provided inside the protection slider 11. The lead screw hole of the protection slider 11 is adapted to the moving lead screw 19. During use, there is clear water in the water tank 6. The water pipe of the water pump 7 is connected to the connecting pipe of the sprinkler head 14. The water pump 7 rotates to pump the clear water in the water tank 6. The water pipe is connected to the connecting pipe to connect the sprinkler head 14 to spray water into the fireplace 13. Thus, when people need to go out, they can quickly extinguish the open fire in the fireplace 13 to avoid the open fire in the fireplace 13 burning unattended when going out and causing a fire. The detector 3 always detects whether there is smoke in the air around the fireplace 13. When the detector 3 detects smoke, the first alarm 4 gives an alarm to prompt people to deal with it to avoid smoke poisoning. The smoke generated in the fireplace 13 is exhausted through the smoke exhaust pipe 1501. After the fire is extinguished with clear water, the smoke increases and the smoke exhaust pipe 1501 cannot quickly exhaust the smoke. The smoke exhaust fan 1505 on the fan pipe 1504 rotates to extract the smoke in the fireplace 13 for exhaustion. Thus, the smoke can be quickly exhausted, avoiding the smoke being unable to be quickly exhausted and entering the house, affecting the air quality in the house. When the second alarm 1503 senses that there is smoke at the connection between the smoke exhaust component 15 and the fireplace 13, it gives an alarm to prompt people that there is smoke. The closing motor 502 drives the closing lead screw 503 to rotate,The closing door 504 slides on the closing rod 501. The two closing doors 504 slide on the closing rod 501 to open and close on one side of the protection cabinet 2. The collecting pump 9 rotates to extract the smoke in the protection cabinet 2 into the collecting box 8. Thus, after the second alarm 1503 alarms, the two closing doors 504 close on one side of the protection cabinet 2 to block the smoke from entering the inner chamber. Then, the collecting pump 9 rotates to pump the smoke into the collecting box 8 for collection, avoiding the smoke unconsciously entering the room and affecting the health of the personnel. The moving motor 18 drives the moving lead screw 19 to rotate, so that the fireplace 13 on the protection slider 11 slides back and forth in the protection cabinet 2. When the sensor 10 senses that someone is approaching, the fireplace 13 slides into the interior of the protection cabinet 2 and presses to trigger the alarm bell 17 to indicate that someone is approaching the fireplace 13. After the alarm bell 17 alarms, the flap motor 16 drives the alarm bell 17 to rotate to turn off the alarm bell 17, so as to indicate to the people in the house that someone is approaching the fireplace 13, avoiding the situation that when adults are doing other things, children climb to the side of the fireplace 13 and curiously touch the fireplace 13, resulting in burns.,

[0029] The working principle of this utility model:

[0030] There is clear water in the water tank 6. The water pipe of the water pump 7 is connected to the connecting pipe of the nozzle 14. The water pump 7 rotates to pump the clear water in the water tank 6. The water pipe is connected to the connecting pipe to connect the nozzle 14 to spray water into the fireplace 13. The detector 3 continuously detects whether there is smoke in the air around the fireplace 13. When the detector 3 detects smoke, the first alarm 4 gives an alarm to prompt personnel to handle it to avoid smoke poisoning. The smoke generated in the fireplace 13 is exhausted through the exhaust pipe 1501. After extinguishing the fire with clear water, the smoke increases and the exhaust pipe 1501 cannot quickly exhaust the smoke. The exhaust fan 1505 on the fan pipe 1504 rotates to extract the smoke in the fireplace 13 for exhaust. When the second alarm 1503 senses smoke at the connection between the exhaust component 15 and the fireplace 13, it gives an alarm to prompt personnel that there is smoke. The closing motor 502 drives the closing lead screw 503 to rotate, so that the closing door 504 slides on the closing rod 501. The two closing doors 504 slide on the closing rod 501 to open and close on one side of the protective cabinet 2. The collection pump 9 rotates to extract the smoke in the protective cabinet 2 into the collection box 8. The moving motor 18 drives the moving lead screw 19 to rotate, so that the fireplace 13 on the protective slider 11 slides back and forth in the protective cabinet 2. When the sensor 10 senses that someone is approaching, the fireplace 13 slides into the interior of the protective cabinet 2 and presses the trigger alarm bell 17 to prompt that someone is approaching the fireplace 13. After the alarm bell 17 gives an alarm, the flap motor 16 drives the alarm bell 17 to rotate to close the alarm bell 17. This device can quickly extinguish the open fire in the fireplace 13 when people need to go out, avoiding the open fire in the fireplace 13 burning unattended and causing a fire when going out. It can quickly exhaust the smoke, avoiding the smoke being unable to be quickly exhausted and entering the house, affecting the air quality in the house. After the second alarm 1503 gives an alarm, the two closing doors 504 close on one side of the protective cabinet 2 to block the smoke from entering the inner room. The collection pump 9 rotates to pump the smoke into the collection box 8 for collection, avoiding the smoke unconsciously entering the room and affecting the health of personnel. It can prompt the people in the house that someone is approaching the fireplace 13, avoiding children climbing to the side of the fireplace 13 when adults are doing other things. Children are curious and may touch the fireplace 13 and get burned.
