Detailed Description

Referring to fig. 1 to 5, the present utility model provides a home gas alarm, comprising: the gas alarm comprises a mounting plate 1, wherein the mounting plate 1 is mounted on a wall surface, and a gas alarm body 2 and a filter screen 3 covering the gas alarm body 2 are mounted on the mounting plate 1.

The working principle and the beneficial effects of the technical scheme are as follows: as shown in fig. 2, the filter screen 3 integrally covers the gas alarm body 2, so that the throughput of gas passing through the gas alarm body 2 is not affected, and suspended particles in smoke in air can be adsorbed and filtered by the filter screen 3, and the phenomenon that oil stains adhere to and block a detection port is avoided.

In one embodiment of the utility model, the screen 3 is removably mounted on the mounting plate 1.

The working principle and the beneficial effects of the technical scheme are as follows: as shown in fig. 1, when the oil stain adhered to the filter screen 3 is more, the filter screen 3 is disassembled for cleaning or replacement so as to prevent the oil stain adhered to the filter screen 3 from influencing the passing of the fuel gas.

In one embodiment of the present utility model, the mounting plate 1 is provided with a plurality of clamping grooves 101 and mounting openings 102 circumferentially around the axial direction of the filter screen 3, the mounting openings 102 are disposed in communication with the clamping grooves 101, the filter screen 3 is provided with mounting blocks 301 that are engaged with the clamping grooves 101, and the mounting blocks 301 can enter the clamping grooves 101 from the mounting openings 102.
