[0006] The gas meter base meter and the lower shell are fixedly connected by screws, and the base meter sealing gasket is arranged between the two;

[0007] The lithium battery box is fixed inside the lower shell by buckles;

[0008] The dry cell box is fixed inside the lower housing by screws;

[0009] The upper shell and the transparent sheet are ultrasonically welded, and a transparent sheet sealing ring is provided between the two;

[0010] The circuit board is fixed inside the lower housing by screws;

[0011] The upper shell and the lower shell are fixed by screws, and a shell sealing ring is provided between the two;

[0012] The upper shell is provided with a button mounting hole;

[0013] The button is installed in the button installation hole provided in the upper shell, and is used in conjunction with the button provided on the circuit board;

[0014] One end of the dry cell compartment cover is connected to the upper shell by a rotating shaft, and the other end is fixedly connected to the upper shell by a buckle;

[0015] The dry cell compartment cover and the upper shell are fixed by screws, and the battery compartment sealing ring is arranged between the two.

[0016] Beneficial effects of the utility model:

[0017] (1) The utility model has a high sealing performance intelligent gas meter, and there is no need to seal the battery and the circuit board separately.
