Smoke recognition devices are also relatively important devices in smart fire protection. Smoke recognition devices are smoke alarms that prevent fires by monitoring the concentration of smoke.

[0003] Smoke alarms are usually installed on the ceiling for use. Dust in the air will enter the interior of the smoke alarm through the smoke inlet, which will affect the smoke alarm and reduce its sensitivity. When a fire occurs, the alarm may be given too late, which will lead to increased property losses. In order to ensure the sensitivity of the smoke alarm, it is necessary to regularly open the outer casing to clean the dust inside. The current smoke alarm casing is more troublesome to connect, and it is more troublesome to disassemble and install, which will waste a lot of time, thereby reducing the dust cleaning efficiency of the smoke alarm.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 3 The utility model provides a new technical solution: an intelligent fire smoke detection identification device, including a connecting base 1, a fixing ring 2 is fixedly sleeved on the outer surface of the connecting base 1, the lower side of the fixing ring 2 is connected to the ceiling, and a plurality of fixing bolts 3 are arranged on the upper side of the fixing ring 2, the fixing ring 2 is fixedly connected to the ceiling through the fixing bolts 3, and a smoke sensor 4 is fixedly connected to the upper side of the connecting base 1. The connecting base 1 and the smoke sensor 4 are existing structures, so no further explanation is given. A shell 10 is sleeved on the outer surface of the smoke sensor 4, and a clamping mechanism is arranged on the connecting base 1 and the shell 10. The connecting base 1 and the shell 10 can be simply and quickly clamped together through the clamping mechanism. The clamping mechanism includes a sliding ring groove 5, a sliding ring 6, a connecting ring groove 8, two clamping block grooves 9, a connecting ring 12 and two clamping blocks 13.

[0031] Further, the sliding ring groove 5 is provided inside the connecting base 1, the sliding ring 6 is slidably connected inside the sliding ring groove 5, the lower side of the sliding ring 6 is fixedly connected with a spring 7, the lower end of the spring 7 is fixedly connected to the bottom wall of the sliding ring groove 5, the connecting ring groove 8 is provided on the upper side of the connecting base 1, the connecting ring groove 8 is connected to the inside of the sliding ring groove 5, two clamping block grooves 9 are provided on the upper side of the connecting base 1, the two clamping block grooves 9 are symmetrically arranged, the two clamping block grooves 9 are connected to the connecting ring groove 8 and the inside of the sliding ring groove 5, and the connecting ring 12 is fixedly connected to the outer shell On the lower side of 10, the connecting ring 12 is matched with the connecting ring groove 8, and the two clamping blocks 13 are respectively fixedly connected to the outer surface of the connecting ring 12, and the two clamping blocks 13 are symmetrically arranged. The two clamping blocks 13 are respectively matched with the two clamping block grooves 9. The outer surface of the shell 10 is provided with a plurality of smoke inlets 11 connected with the interior. The upper side of the shell 10 is fixedly connected with a connecting plate 14, and the connecting plate 14 is provided with a smoke inlet hole, which is connected with the interior of the shell 10. A rubber pad 15 is fixedly connected to the top wall of the sliding ring groove 5, and the rubber pad 15 can contact with the clamping block 13.

[0032] Furthermore, during the use of the smoke alarm, dust will enter the interior through the smoke inlet 11 and the smoke inlet holes on the connecting plate 14, thereby affecting the sensitivity of the smoke sensor 4. At this time, the dust needs to be cleaned. At this time, the staff pushes the shell 10 upwards and then rotates the shell 10. The shell 10 drives the connecting ring 12 to rotate synchronously, and the connecting ring 12 drives the two clamping blocks 13 to rotate. Then the two clamping blocks 13 will move to the positions of the two clamping block grooves 9 respectively, and then the clamping state of the clamping blocks 13 and the clamping block grooves 9 will be released, and then the shell 10 can be pulled off. At the same time, the shell 10 will drive the connecting ring 12 and the two clamping blocks 13 and the connecting plate 14 to be removed synchronously, and then the staff can clean the dust on the smoke sensor 4. When the cleaning is completed and the installation is carried out, the clamping block 13 is aligned with the clamping block groove 9 and then the shell 10 is pushed. The shell 10 drives the connecting ring 12 and The two clamping blocks 13 move toward the inside of the sliding ring groove 5, and then the clamping blocks 13 will push the sliding ring 6 to move. At this time, the spring 7 begins to become a compressed state, and finally the shell 10 is rotated. The shell 10 drives the connecting ring 12 and the two clamping blocks 13 to rotate, so that the two clamping blocks 13 are misaligned with the two clamping block grooves 9. After release, the shell 10 will not fall from the inside of the sliding ring groove 5. At the same time, the spring 7 will reset from the compressed state and push the sliding ring 6 to reset. The sliding ring 6 pushes the connecting ring 12 and the clamping blocks 13 to reset, and then pushes the clamping blocks 13 to contact with the rubber pad 15. The larger friction force of the rubber pad 15 will make the clamping blocks 13 no longer move. In this way, the shell 10 of the smoke alarm can be clamped, so that the shell 10 is easier to disassemble and install, thereby improving the efficiency of cleaning dust inside the smoke alarm.

[0033] Working principle: During the use of the smoke alarm, dust will enter the interior through the smoke inlet 11 and the smoke inlet holes on the connecting plate 14, thereby affecting the sensitivity of the smoke sensor 4. At this time, the dust needs to be cleaned. At this time, the staff pushes the outer shell 10 upwards, and then rotates the outer shell 10. The outer shell 10 drives the connecting ring 12 to rotate synchronously, and the connecting ring 12 drives the two clamping blocks 13 to rotate. Then, the two clamping blocks 13 will move to the positions of the two clamping block grooves 9 respectively, and then the clamping state of the clamping blocks 13 and the clamping block grooves 9 will be released, and then the outer shell 10 can be pulled off, and at the same time, the outer shell 10 will drive the connecting ring 12 and the two clamping blocks 13 and the connecting plate 14 to be removed synchronously, and then the staff can clean the dust on the smoke sensor 4. When the cleaning is completed and the installation is carried out , align the clamping block 13 with the clamping block groove 9 and then push the shell 10. The shell 10 drives the connecting ring 12 and the two clamping blocks 13 to move toward the inside of the sliding ring groove 5, and then the clamping block 13 will push the sliding ring 6 to move. At this time, the spring 7 begins to become compressed. Finally, the shell 10 is rotated. The shell 10 drives the connecting ring 12 and the two clamping blocks 13 to rotate, so that the two clamping blocks 13 are misaligned with the two clamping block grooves 9. After release, the shell 10 will not fall from the inside of the sliding ring groove 5. At the same time, the spring 7 will reset from the compressed state and push the sliding ring 6 to reset. The sliding ring 6 pushes the connecting ring 12 and the clamping block 13 to reset, and then pushes the clamping block 13 to contact with the rubber pad 15. The larger friction force of the rubber pad 15 will make the clamping block 13 no longer move.
