Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention, i.e., the described embodiments are only some, but not all embodiments of the invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in FIG. 2, the smoke detector maze that relates to in this application includes maze base 1 and PCB circuit board 2, and PCB circuit board 2 embedding is installed on maze base 1, and maze base 1 is inside to be equipped with emission signal lamp 14 and to receive signal lamp 13, emission signal lamp 14 and to receive signal lamp 13 and PCB circuit board 2 electric connection. In the prior art, in order to improve the sensitivity, the emission signal lamp 14 and the reception signal lamp 13 are usually disposed at an angle, and in addition, a left light blocking sheet 11 and a right light blocking sheet 12 are symmetrically disposed between the emission signal lamp 14 and the reception signal lamp 13 to form a horn-shaped opening and form an air channel.
When smoke enters the interval of the labyrinth base 1 from the air passage, infrared light emitted by the transmitting signal lamp 14 is scattered when encountering the smoke, the receiving signal lamp 13 converts an optical signal into an electric signal through the photoelectric conversion circuit after receiving the electric signal and transmits the electric signal to the processing chip on the PCB 2, and the processing chip judges that the buzzer and the LED illuminator are started if the measured value exceeds a threshold value, and gives an alarm to attract attention of people.
Referring to fig. 1, in an embodiment of the present invention, a blocking structure of a labyrinth base 1 of a smoke detector for preventing moisture and heat fog from condensing includes a left light blocking sheet 11 and a right light blocking sheet 12, the left light blocking sheet 11 and the right light blocking sheet 12 are symmetrically disposed, and two crotch-shaped structures 15 are disposed at tops of the left light blocking sheet 11 and the right light blocking sheet 12.
Wherein, the left light blocking sheet 11 has a lower crotch near the side of the emission signal lamp 14, and the right light blocking sheet 12 has a lower crotch near the side of the right light blocking sheet 12, so as to prevent blocking the light signal.
Compared with the prior art, the embodiment of the utility model provides a pair of anti damp and hot water smoke detector maze base 1 shelters from structure in left light barrier 11 and right light barrier 12 top all have crotch column structure 15 for the drop of water that left light barrier 11 and right light barrier 12 top naturally condensed can fall into in the crotch seam along crotch column structure 15 among, prevent that the drop of water from producing the refraction to the optical signal, stopped the wrong report that the drop of water condenses and causes under the damp and hot environment, the interference killing feature is strong.
In one embodiment, the height difference Δ H between the two crotch-like structures 15 is favorable for condensed water drops to fall off.
In this embodiment, Δ H is in the range of 0.1-1mm, so that the line connecting the tops of the two ends of the fork forms a certain angle with the horizontal direction to conform to the angle between the emission signal lamp 14 and the reception signal lamp 13.
The foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
