DESCRIPTION OF EMBODIMENTS

[0021] This section will describe the specific embodiments of the present invention in detail. The preferred embodiments of the present invention are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the statement of the text part of the description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention. However, the accompanying drawings shall not be construed as a limitation to the protection scope of the present invention.

[0022] In the statement of the present invention, it should be understood that orientation statements, such as orientation or position relationships indicated by up, down, front, back, left, right, etc., are based on the orientation or position relationships shown in the accompanying drawings and are only to facilitate the statement of the present invention and simplify the statement, rather than indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0023] In the statement of the present invention, several means one or more, a plurality of means two or more, greater than, less than, and more than, etc. are understood to exclude the original number, and above, below, within, etc. are understood to include the original number. If there is a statement of first and second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the order of indicated technical features.

[0024] In the statement of the present invention, unless otherwise explicitly specified, words such as setting, mounting and connection should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0025] Referring to FIG. 1 to FIG. 3, a smoke exhaust pipe comprises: a pipe body 1, a mounting part 2 is inserted into one end of the pipe body 1, a rainproof pipe 3 is sealingly connected to the mounting part 2, and an outer end opening of the rainproof pipe 3 is inclined downward. During use, the mounting part 2 is inserted from the outdoors to the indoors through a pre-formed mounting hole, then the mounting part 2 is inserted into the pipe body 1, and the rainproof pipe 3 is mounted on the mounting part 2. By using the pipe body 1 to mount and support the mounting part 2, mounting is simple and convenient.

[0026] The pipe body 1 is composed of a plurality of pipelines that are inserted together, and the plurality of pipelines are fixed by pipe hoops 5.

[0027] The pipelines comprise straight pipes and elbow pipes (as shown in FIG. 3).

[0028] The mounting part 2 comprises a connecting pipe 21 and a fixing plate 22, the connecting pipe 21 is inserted into the pipe body 1 and then fixed by the pipe hoops 5, and the rainproof pipe 3 is movably mounted on the fixing plate 22.

[0029] A bottom and two sides of the fixing plate 22 are provided with a plurality of hooks 23 with upward openings, a left side of the rainproof pipe 3 is folded outward to form folded edges 31, the folded edges 31 located on two sides are provided with notches 32, and the folded edges 31 are able to be inserted into corresponding hooks 23. During mounting, the notches 32 are used to make the hooks 23 cross the corresponding folded edges, then the rainproof pipe 3 is moved downward, and the folded edges 31 are inserted into the corresponding hooks 23, such that mounting of the rainproof pipe 3 is realized. The operation is simple and convenient.

[0030] The hooks 23 are formed by stamping, thereby facilitating processing.

[0031] The rainproof pipe 3 is internally provided with a grille 4. Bugs or other small animals can be prevented from entering the smoke exhaust pipe.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Under the invention concept of the present invention, equivalent structural transformations made using the contents of the description and drawings of the present invention, or directly or indirectly used in other relevant technical fields are all included in the patent protection scope of the present invention.
