Since the combustion space is located in the heat collecting cavity formed in the heat collecting member 32, in order to immediately discharge the exhaust gas generated in the combustion space, the heat collecting member 32 is formed with exhaust gas holes 34, and the combustion products are discharged from the exhaust gas holes 34. In this embodiment, the fuel used in the pumping device can be a gaseous fuel, such as butane, or a liquid fuel, such as gasoline.
The heat conducting member 31 includes a heat conducting core 35 and a heat conducting shell 33, the heat conducting core 35 is connected to the heat collecting member 32, and the heat conducting shell 33 is wrapped on the surface of the heat conducting core 35.
