Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0017] The present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See also Figures 1 to 3 As shown, the efficient heating structure of a gas boiler involved in this embodiment includes a boiler body 1 with a pot mouth facing upward, a combustion tube 2 passing through the boiler body 1 is provided inside the boiler body 1, both ends of the combustion tube 2 are connected to the outside, one end of the combustion tube 2 is connected to an input pipe (not shown) for supplying gas, a venturi tube 3 is connected in series between the input pipe and the combustion tube 2, and a long open flame 4 is provided between the venturi tube 3 and the combustion tube 2.
