[0002] Firefighting is the elimination of hidden dangers and prevention of disasters (i.e., the prevention and resolution of man-made and natural or accidental disasters encountered by people in their lives, work, and studies). Smoke detectors prevent fires by monitoring the concentration of smoke. They can be widely used in shopping malls, hotels, shops, warehouses, computer rooms, residences, and various fire alarm systems for fire safety detection. Smoke sensors have a built-in buzzer that emits a loud sound when an alarm is triggered. As a very important part of the fire protection field, smoke detectors are receiving increasing attention.

[0003] Smoke detectors operate in environments with a lot of dust, and long-term accumulation can affect the accuracy of the alarm. Therefore, regular cleaning and maintenance are necessary. Existing labyrinth smoke detectors require the removal of multiple components when cleaning and maintaining their built-in labyrinth parts, making it difficult to quickly and conveniently clean the dust inside the labyrinth parts.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model discloses a fire safety monitor, including a housing 1. The top of the housing 1 has a clearance hole 2. A circuit board 15 is installed in the inner cavity of the housing 1. A labyrinth component 3, which cooperates with the circuit board 15 and has its top end passing through the clearance hole 2, is installed in the inner cavity of the housing 1. A smoke inlet structure 4, which can cover the clearance hole 2 and cover the labyrinth component 3, is detachably connected to the top of the housing 1. The smoke inlet structure 4 includes a smoke inlet cylinder 5 and a mounting ring 6. The mounting ring 6 is fixedly connected to the bottom end of the smoke inlet cylinder 5 and covers the clearance hole 2. The outer wall of the smoke inlet cylinder 5 is uniformly provided with grooves 9 along its circumference. The bottom of the mounting ring 6 is uniformly connected with hooks 12 that can extend into the inner cavity of the clearance hole 2 along its circumference. The inner wall of the clearance hole 2 is provided with a groove that engages with the hooks 12.

[0019] The maze component 3 contains conventional components known in the prior art, such as light emitters and light receivers, which will not be described in detail here.

[0020] When the smoke inlet structure 4 is installed on the housing 1, the mounting ring 6 covers the clearance hole 2, and the hook 12 extends into the clearance hole 2 and can engage with the slot.

[0021] The bottom of the mounting ring 6 can be fixedly connected to the positioning post, and the housing 1 can be provided with positioning holes that cooperate with the positioning post.

[0022] Specifically, the smoke inlet structure 4 includes an insect-proof cover 7 and insect-proof holes 8. The insect-proof cover 7 is generally I-shaped and is fitted onto the smoke inlet cylinder 5. The outer wall of the insect-proof cover 7 is evenly provided with insect-proof holes 8.

[0023] In this embodiment, the insect-proof cover 7 is fitted onto the smoke inlet duct 5, and by opening the insect-proof hole 8, it can prevent insects from entering the inner cavity of the smoke inlet duct 5.

[0024] Specifically, the smoke inlet structure 4 also includes a top plate 10, which is detachably connected to the smoke inlet cylinder 5 and presses against the insect-proof cover 7.

[0025] The top opening of the smoke inlet duct 5 is provided, and the top of the inner wall of the smoke inlet duct 5 is formed with an internal thread.
