Based on the above, a special-shaped shading wall is arranged between the infrared transmitting tube and the infrared receiving tube, and the cross section of the special-shaped shading wall is concave.
Based on the above, the infrared receiving tube is provided with the shielding case.
Based on the above, the maze upper cover sets up LED display screen and fire alarm indicator, the maze upper cover is detained through circular erection column and is established on the maze base, the mounting hole setting of circular erection column is on wherein two maze structure shade pieces.
Based on the above, still include the mounting panel, be provided with installation slot on the mounting panel, labyrinth base's outer wall be provided with the installation string post of installation slot adaptation.
Compared with the prior art, the utility model has substantive characteristics and progress, in particular to the smoke detector labyrinth, which can lead smoke to smoothly enter and exit the labyrinth cavity, and simultaneously prevent all light rays outside including infrared light from entering the labyrinth cavity, thereby reducing the false alarm rate; the mounting structure is simple to disassemble and assemble and easy to clean.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic side view of the present invention.
In the figure: 1. a labyrinth base; 2. a labyrinth upper cover; 3. an infrared emission tube; 4. an infrared receiving tube; 5. an insect-proof net; 6. a labyrinth structured shade; 61. a first labyrinth shade; 62. a second labyrinth shade; 63. a third labyrinth shade; 64. a fourth labyrinth shade; 7. a special-shaped shading wall; 8, LED display screen; 9. a fire alarm indicator light; 10. mounting holes; 11. and (5) mounting a hanging column.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1 and 2, a smoke detector labyrinth comprises a labyrinth base 1, an upper labyrinth cover 2, an infrared transmitting tube 3, an infrared receiving tube 4 and an insect-proof net 5, wherein the infrared transmitting tube 3 and the infrared receiving tube 4 are installed in the labyrinth base 1, the infrared transmitting tube 3 and the infrared receiving tube 4 are respectively welded with a printed board with components and parts on the back side of the labyrinth base 1 through a lead hole, and a shielding cover is arranged on the infrared receiving tube 4; a special-shaped shading wall 7 is arranged between the infrared transmitting tube 3 and the infrared receiving tube 4, and the cross section of the special-shaped shading wall 7 is concave;
a labyrinth base 1 is provided with a labyrinth structure shading sheet 6, and the labyrinth structure shading sheet comprises a first labyrinth shading sheet 61 arranged along the outer edge of the labyrinth base 1, a second labyrinth shading sheet 62 connected with the first labyrinth shading sheet at an obtuse angle, a third labyrinth shading sheet 63 connected with the second labyrinth shading sheet 62 at an obtuse angle, and a fourth labyrinth shading sheet 64 connected with the second labyrinth shading sheet 62 at an acute angle; the labyrinth cavity formed by the labyrinth base 1 and the labyrinth upper cover 2 is covered by the insect-proof net 5.
The structure that the first labyrinth shade and the second labyrinth shade are connected in an obtuse angle mode 62 can enable smoke to enter the cavity smoothly; the structure that second maze anti-dazzling screen 62 with third maze anti-dazzling screen 63 obtuse angle is connected, and the structure that second maze anti-dazzling screen 62 with fourth maze anti-dazzling screen 64 acute angle is connected can effectively reduce the speed that the air current got into the labyrinth cavity, blocks sand and dust, guarantees simple flue gas dispersion as far as possible and gets into the cavity, and keeps the certain time, and does not carry out the labyrinth cavity rapidly by the air current. Sufficient smoke inlet amount provides a good foundation for the infrared receiving tube 4 to acquire stable data in time, and is the key for the smoke detector to give an alarm in time and give out less false alarm.
