Detailed Description

It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

In addition, if directional indications (such as up, down, left, right, front, and rear … …) are involved in the embodiment of the present utility model, the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.

The utility model provides a smoke exhaust pipe and a protective cover for a gas water heater based on the problem that the existing gas water heater is used in a windy and rainy environment, and aims to solve the problem that the gas water heater is used in the windy and rainy environment, particularly solve the problem that the smoke exhaust pipe cannot be vertically installed, and improve the comfort and safety of use of users.

Referring to fig. 1, the utility model provides a smoke exhaust pipe for a gas water heater, which comprises a smoke exhaust pipe 1 body, wherein a plurality of smoke outlets 2 are formed at the tail end of the smoke exhaust pipe body, a protective cover 4 is externally arranged at the smoke outlets 2, the protective cover 4 comprises a cover body and a plurality of telescopic rod groups 5 arranged in the cover body, the diameter of the cover body is more than or equal to 1.23 times of the diameter of the smoke exhaust pipe 1, the length of the cover body is more than or equal to the maximum edge distance of the smoke outlets 2 plus twice the diameter of the smoke outlets in the radial direction of the smoke exhaust pipe 1, after the installation is finished, the protective cover 4 can effectively cover all the smoke outlets 2 under any condition, the number of the telescopic rods 5 is more than or equal to 6, the distribution interval of the telescopic rod groups is matched with the smoke outlets 1, and the telescopic rod groups are more than or equal to 2 layers of the telescopic rod groups are distributed in a circumferential direction. The extension part 6 of the telescopic rod 5 extends into the smoke outlet to lock the smoke exhaust pipe 1 under the action of the spring 7 in the telescopic rod 5, when the telescopic rod 5 is contracted, the smoke exhaust pipe 1 can pass through the space between the telescopic rods, and the linear distance between the smoke exhaust pipe and the protective cover which can relatively move is not more than the maximum distance of the smoke outlet.

When the tail end of the protection cover covers the tail end of the smoke exhaust pipe beyond 16mm, the protection net should be used at the tail end of the protection cover, the protection net should not affect the smoke exhaust effect, a sphere with the diameter of 16mm should not pass through the protection net under the action of 5N, the preferable structure is shown in figure 10, but the structure is not limited to the structure, and the telescopic rod stretches out into the smoke exhaust port to lock the smoke exhaust pipe under the action of the spring in the telescopic rod.
