Smoke collector case

#1. Field of the Invention

#The invention relates to a smoke collector case and, more particularly, to a smoke collector case that can provide the smoke detection more effectively and quickly.

#2. Description of the Related Art

#The drawings included herein provide a further understanding of the invention. A brief introduction of the drawings is as follows:

#FIG. 1 is a schematic diagram of a smoke collector case known in the prior art;

#FIG. 2 is an exploded view of a smoke collector case according to the present invention;

#Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.

#Referring to FIG. 2, FIG. 3, and FIG. 4, the present invention provides a smoke collector case 20 that comprises a cylindrical hollow housing 21. The hollow housing 21 includes a base 22 and an upper cover 23. The base 22 is disk-shaped and further includes a plurality of first fastening members 24 and second fastening members 25, respectively protruding from the bottom and top surface thereof. The second fastening members 25 are for connecting with the upper cover 23. The base 22 includes a first fixation base 26 and a second fixation base 27 used for mounting the smoke detector.

#The upper cover 23 is cylindrical and opened at the bottom portion. Slots 28 are mounted on sidewall of the upper cover 23 and are for the purpose of being the passage of fire smoke. As this result, the fire smoke can be detected by the smoke detector 40 inside of the hollow housing 21 as shown as in FIG. 6. includes a plurality of slots 28 through which smoke can penetrate within the case 21 to the smoke detector 40. The upper cover 23 internally includes a plurality of first fins 29, like a “labyrinth”, that are spaced apart from one another and set near to the sidewall of the upper cover 23. The placement of first fins 29 hence defines a smoke path to guide the fire smoke is guided to the smoke detector 40. The first fins 29 are shaped in an “I” manner cross-sectionally. Each first fin 29 has an outer sidewall 30 and an inner sidewall 31 that are further connected to each other via a connecting portion 32 between the outer and inner sidewall 30 and 31. A second fin 33 is placed between every two first fins 29. The second fins 33 are shaped in a bar manner cross-sectionally. The upper cover 23 is fixedly fastened to the base 22 through the second fastening members 25, thereby defining a preferred embodiment of the invention.
