Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand the invention and to implement the invention, and are not intended to limit the scope of the invention in any way.

Referring to fig. 1, an embodiment of the present invention provides an intelligent gas alarm, which includes a housing, where the housing includes an upper housing 1, a lower housing 2, and an installation accessory 3, which are detachably connected in sequence from top to bottom.

The upper case 1 is for accommodating an electric circuit part (not shown in the drawings) of the gas alarm, which is a main body part of the housing, and the lower end is detachably connected to the lower case 2. For example, the upper housing 1 and the lower housing 2 may be connected by a snap 4.

Gas detection air holes 11 are formed in the surface of the upper shell 1, the gas detection air holes 11 are uniformly distributed in the surface of the upper shell 1 in a concentric circle arrangement mode, and the space of the upper surface of the upper shell 1 is fully utilized. The cross section of the whole shell is in a square shape with four corners provided with chamfers.

The upper surface of the upper shell 1 is also provided with a self-checking switch 12 which can be arranged below the gas detection hole 11, so that the surface space of the upper shell 1 is further fully utilized. The interior of the upper shell 1 is also provided with a standby power supply (not shown in the figure), which can increase the cruising ability of the gas alarm.

The mounting fitting 3 is a sheet structure, and a mounting hole 31 for matching with a screw is formed on the surface of the mounting fitting. The lower housing 2 is provided in the middle with a connection area 21 adapted to the mounting fitting in shape, in this embodiment, the sheet-like structure is a circular plate, and the corresponding connection area 21 on the lower housing is a circular groove provided on the lower surface of the lower housing, and the circular plate can be just snapped into the circular groove. The outer edge of the wafer is provided with a plug 32 along the arc direction, a slot 22 matched with the plug 32 is arranged on the connecting area 21 of the lower shell 2, when the connecting area and the wafer are matched, the accessory is installed in a rotating mode by taking the circle center of the wafer as an axis, and the plug 32 is embedded into the slot 22 to be fixed.
