Description

Smoke pipe connection structure for gas heating water heater Technical Field The utility model relates to the technical field of water heaters, in particular to a smoke pipe connecting structure for a gas heating water heater. Background The gas heating water heater is widely applied in the aspects of modern household heating and hot water supply, generates heat by burning gas so as to meet the demands of people on indoor heating and domestic hot water, and in the operation process of the gas heating water heater, the smoke tube plays a vital role and is responsible for discharging waste gas generated by burning outdoors, meanwhile, the outside air can be ensured to normally enter the furnace body to maintain the combustion process, and the stability and the tightness of the smoke tube connection are directly related to the safe operation and the use efficiency of the gas heating water heater. In traditional tobacco pipe connected mode, often adopt simple grafting mode, for example, with two tobacco pipes direct insertion connection, this kind of connected mode lacks effectual fixed knot and constructs, in the gas heating water heater operation in-process, because the vibration of machine or receive the circumstances such as external slight collision, pull, the phenomenon that drops very easily takes place for the tobacco pipe, in case the tobacco pipe drops, can not only lead to the unable normal work of gas heating water heater, can make the waste gas that the burning produced leak indoor moreover, cause serious threat to indoor personnel's health and safety, and in actual use, because the grafting position is difficult to reach totally inseparable laminating, and then lead to waste gas to leak out very easily from the junction. Thus, the smoke pipe connecting structure for the gas heating water heater is provided for solving the problems. Disclosure of utility model The utility model aims to provide a smoke pipe connecting structure for a gas heating water heater, which aims to solve the problems that the smoke pipe connection is not tight enough and the sealing effect is poor in the prior art. In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model relates to a smoke pipe connecting structure for a gas heating water heater, which comprises a water heater body, wherein a first smoke pipe is arranged on the upper surface of the water heater body, a threaded connecting pipe is fixedly arranged on the outer surface of the first smoke pipe, a first abutting ring is fixedly arranged on the outer surface of the first smoke pipe, the first abutting ring is arranged at one end of the first smoke pipe, a first sealing ring is fixedly arranged in the first abutting ring, a second smoke pipe is arranged above the first smoke pipe, a connecting mechanism is fixedly arranged on the outer surface of the second smoke pipe, a second abutting pipe is fixedly arranged on the outer surface of the second smoke pipe, and a second sealing ring is fixedly arranged in the second abutting pipe.
