In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

Certain assembly gaps are arranged at the opening of the top fan top cylinder 3 of the shell of the upper pumping forced exhaust type gas water heater. Because the actual use environments of the gas water heater are different, if the gas water heater is used in a relatively severe environment for a long time, the service life of the gas water heater can be greatly reduced. The design concept of the invention is that the existing gap is sealed by adding the sealing ring 4 on the top cylinder 3 of the fan of the gas water heater. As shown in fig. 1-2, the utility model discloses a gas water heater, including casing 1, fan subassembly 2 and top section of thick bamboo 3, fan subassembly 2 is arranged in casing 1, the air intake of fan is towards the bottom plate of casing 1, set up through-hole 11 on casing 1's the epipleural, fan subassembly 2's blast pipe passes through-hole 11 on the epipleural and stretches out casing 1 outside, the blast pipe is close to epipleural department and is equipped with sealing washer 4, set up seal structure on the epipleural of through-hole 11 department, make sealing washer 4 and seal structure, the blast pipe contact, in order to increase the area of contact of sealing washer 4 and epipleural, promote the sealed effect of sealing washer 4 greatly.

The sealing ring 4 is made of high-temperature-resistant silica gel or other high-temperature foaming materials, and the section of the sealing ring 4 can be circular, rectangular, T-shaped, semicircular and the like.

The sealing structure is a bending part 12 connected to the through hole 11, the bending part 12 protrudes out of the upper side plate of the shell 1, the bending part 12 is an annular structure with an open middle, and the inner wall of the bending part 12 is in surface contact or line contact with the sealing ring 4. In fig. 2, the bending portion 12 includes a top wall and a side wall, the top end of the side wall is fixedly connected to the outer ring of the top wall, and the bottom end of the side wall is fixedly connected to the through hole 11 of the upper side plate. The angle between the top wall and the side wall may be set to 90-120 or the inner wall of the bend 12 may match the outer wall of the sealing ring 4.

The bent portion 12 and the upper side plate are integrally formed by a stamping process, and as shown in fig. 2, the bent portion 12 is formed into a boss by using an arc punching. The process is simple, the bent part 12 and the upper side plate are formed in one step, and the production efficiency is improved.

In order to improve the sealing effect, the inner diameter of the sealing ring 4 is smaller than the outer diameter of the exhaust pipe, the outer diameter of the sealing ring 4 is larger than the inner diameter of the central hole of the annular bending part 12, and through the size design of key parts, the sealing ring 4, the upper side plate and the exhaust pipe are matched more reasonably, effectively sealed and mounted more efficiently.
