In the present embodiment, an exhaust pipe 16 is further disposed inside the air collecting base 10, a top end of the exhaust pipe 16 is in sealed communication with the exhaust interface 12, and a bottom end of the exhaust pipe 16 is used for being inserted into the mounting interface 15. As shown in fig. 8, in the present embodiment, the exhaust pipe 16 is integrally formed with the exhaust interface 12, and the exhaust pipe 16 is also in a circular pipe shape. In order to avoid the situation that the flow cross section is reduced easily due to the arrangement of the exhaust duct 16 because air is to flow through the mounting interface 15, the exhaust duct 16 in the present embodiment includes a large diameter section with a larger diameter and a small diameter section with a smaller diameter, wherein the diameter of the large diameter section is the same as that of the exhaust interface 12. The small diameter section of the exhaust pipeline 16 is inserted into the installation interface 15, and the diameter of the small diameter section is reduced, so that the annular space between the small diameter section and the installation interface 15 is enlarged, and the condition that the flow cross section is too small is avoided.

The working process of the invention is as follows: when the water heating furnace 1 is connected with a coaxial double-channel exhaust chimney, the coaxial double-channel exhaust chimney is directly communicated with a reserved interface arranged on the water heating furnace 1 in a sealing way without installing a conversion joint 9; when the two chimneys are connected to water heater 1, adapter 9 needs to be installed this moment, during the installation, the bottom port of exhaust pipe 16 and the sealed intercommunication of 6 air outlets of fan, the pipeline that corresponds of 6 air outlets of fan department only need insert in exhaust pipe 16's the bottom port can, simultaneously, installation interface 15 can cover the periphery side of reserving interface 4, it needs to explain, reserve interface 4 and be equivalent to the one section pipe that sets up on water heater 1, during the installation, the terminal surface of installation interface 15 can with reserve 1 top surface laminating contact of interface 4 periphery side of water heater, thereby play the sealed effect of intercommunication, also can adopt seal structure to seal the intercommunication between installation interface 15 and the reservation interface 4 in other embodiments. And then the exhaust chimney 8 is inserted into the exhaust interface 12, and the air inlet chimney 7 is inserted into the air inlet interface 11, so that the installation of the double chimneys is completed. During use, exhaust gas generated by natural gas is conveyed into the exhaust chimney 8 through the exhaust pipeline 16 and the exhaust interface 12, and outside air is pumped into the water heater 1 through the air inlet interface 11, the inner cavity of the gas collecting base 10 and the mounting interface 15.
To sum up, the embodiment of the invention provides a chimney adapter for a gas heating water heater, which enables the water heater 1 to be simultaneously suitable for installation of a coaxial double-channel exhaust chimney and a double chimney by adopting the adapter of the invention, avoids the situation that a reserved port 5 and an additional pipeline for installing the double chimney need to be reserved in the water heater 1, simplifies the structural design of the water heater 1, and avoids the waste of related accessories.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
