[ detailed description ] embodiments

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is the utility model provides a smoke detector shell structure schematic diagram in the embodiment one, this embodiment can be applicable to the technical field that the detector was felt to the smoke, and this smoke detector shell specifically includes following structure: including link plate 1, base 2 and cavity shell 3, link plate 1 is located the lower part of base 2, installs cavity shell 3 on the base 2, is used for laying the electronic components of smoke detector in the cavity shell 3.

As shown in fig. 2, a chimney 4 is disposed in the middle of the top of the chamber housing 3, and is used for allowing a smoke detection module in the chimney 4 to detect smoke.
