[0002] The gas wall-mounted boiler has a powerful home central heating function and can meet the heating needs of multiple rooms. Each room can set a comfortable temperature as needed, and the heating of a certain room can be turned off as needed. It can also provide a large flow of constant temperature sanitary hot water for use in home bathing, kitchen and other places.

[0003] After searching, the patent announcement number CN214680718U discloses a filtering mechanism of a gas wall-mounted boiler flue filter, and its structure includes a box body, a display screen, a power switch, a temperature adjustment switch, a cold water inlet, a hot water outlet, a gas inlet, a smoke outlet, a smoke pipe and a filtering device. The filtering mechanism of the gas wall-mounted boiler flue filter described in the utility model is achieved by installing a semicircular clamp ring on the filtering mechanism of the gas wall-mounted boiler flue filter, so that the smoke pipe and the filtering device can be fixedly connected, and by arranging a spring, a sliding rod and a pull button on the upper end of the semicircular clamp ring, the semicircular clamp ring can provide an inward force through the spring when not in use, so that the two semicircular clamp rings are tightly closed and the fixed ring is clamped.
