TECHNICAL FIELDThe present invention relates to the field of gas water heaters, in particular to a smoke exhaust pipe.
BACKGROUNDExisting gas water heaters discharge smoke gas generated by combustion through smoke exhaust pipes. A pipe opening at one end of the smoke exhaust pipe extends to the outdoors. In order to prevent rainwater from entering, pipe openings of some smoke exhaust pipes are provided with rain shields.
For example, a patent document with a publication number CN217421332U discloses a rainproof cap structure of a smoke exhaust pipe, comprising a right-angle elbow pipe and a beveled pipe. A lower end opening of the right-angle elbow pipe is oriented vertically and welded to the smoke exhaust pipe, and an upper end opening is oriented horizontally. An inner diameter of the beveled pipe is greater than an outer diameter of the upper end opening of the right-angle elbow pipe. A right end of the beveled pipe is an oblique cut with a downward opening, and a left end is a horizontal end that is sleeved on an outer side of the upper end opening of the right-angle elbow pipe and fixed by welding. In the technology, the rainproof structure is welded to a pipe opening. Since one end of a gas water heater is located outdoors, difficult mounting will be caused by welding in advance, and inconvenient operation will be caused by welding during mounting.
For another example, a patent document with a publication number CN219100608U discloses a rainproof device of a smoke exhaust pipe, comprising an arc-shaped top plate, a back plate and a positioning device. A top of the back plate is connected to an end part of the arc-shaped top plate. The positioning device comprises a clip strip, and the clip strip is fixedly mounted on the back plate and located on one side away from the arc-shaped top plate. The rainproof structure in the technology is inserted and mounted on a positioning plate, however, the positioning plate needs to be fixed on a wall, thus, increasing mounting difficulty.
Therefore, a smoke exhaust pipe is proposed to solve the above technical problems.

As a further improvement of the above technical solution, the mounting part comprises a connecting pipe and a fixing plate, the connecting pipe is inserted into the pipe body and then fixed by the pipe hoops, and the rainproof pipe is movably mounted on the fixing plate.
As a further improvement of the above technical solution, a bottom and two sides of the fixing plate are provided with a plurality of hooks with upward openings, a left side of the rainproof pipe is folded outward to form folded edges, the folded edges located on two sides are provided with notches, and the folded edges are able to be inserted into corresponding hooks.
As a further improvement of the above technical solution, the hooks are formed by stamping.
As a further improvement of the above technical solution, the rainproof pipe is internally provided with a grille.
Beneficial effects of the present invention are as follows: through arrangement of the rainproof pipe with the downward opening, an effective rainproof effect can be achieved; and meanwhile, the rainproof pipe is mounted through the mounting part, and the mounting part is inserted into the pipe body, such that mounting and disassembly are convenient.
