[0025] like Figure 1-Figure 4 As shown:

[0026] Embodiment 1:

[0027] The heater includes an outer shell 2, an inner shell 20 and a base 21. The inner shell 20 is inserted into the inner shell 2, and the base 21 is arranged on one side of the outer shell 2. A rear plate 4 is arranged at one end of the inner shell 20. The rear plate 4 is assembled with a burner 5 and one end of an ejector tube 7, and the other end is assembled with one end of a gas pipe 7. The combination of the ejector tube 7 and the gas pipe 70 forms a Z-shape. The ejector tube 7 and the gas pipe 70 are an integrated structure, which improves the safety of the gas heater. A burner 50 is arranged around the burner 5, and the heater realizes a gas heating structure.

[0028] A protruding burner head 5 is provided in the middle of the rear plate 4, and a burner 50 is provided around the burner head 5, which is an adjacent structure. The burner 50 has a structure for igniting the gas discharged from the burner head 5, so that the heater realizes gas heating.
