[0009] As a further improvement of the above technical solution, a connecting piece is arranged at the bottom of the smoke exhaust shell, and the connecting piece is fixedly connected to the water tank by bolts.

[0010] As a further improvement of the above technical solution, a limiting groove is provided on the connecting piece, a coil pipe is provided outside the water tank, and the coil pipe is embedded in the limiting groove.

[0011] As a further improvement of the above technical solution, the burner is fixedly installed at the bottom of the water tank by bolts.

[0012] As a further improvement of the above technical solution, two connecting ears are provided at the bottom of the smoke exhaust shell, and mounting holes are provided on both sides of the support shell.

[0013] As a further improvement of the above technical solution, a first connecting plate and a second connecting plate are provided on one side of the support shell, a first threaded hole is opened on the water tank, the first connecting plate is fixed on the water tank by bolts in cooperation with the first threaded hole, a second threaded hole is opened on the burner, and the second connecting plate is fixed on the burner by bolts in cooperation with the second threaded hole.

[0014] As a further improvement of the above technical solution, both the first connecting plate and the second connecting plate are integrally formed on the support shell by stamping.

[0015] The beneficial effects of the present utility model are as follows: by providing a support shell to fixedly support the smoke exhaust shell, the water tank and the burner, the installation stability is improved; at the same time, since the support shell wraps the water tank and the burner, the heat insulation performance can be improved.
