Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

When being installed, the fresh air pipe used in the existing air conditioner is usually fixed together with a copper pipe structure of the air conditioner and then penetrates out of a machine and a wall body to be connected with an outdoor exchanger. On the basis, in order to utilize the pipe running space to the maximum extent, the design of the special-shaped fresh air pipe is provided.

And in the part passing through the wall body, in order to improve the air quantity of the fresh air pipe as much as possible, the special-shaped fresh air pipe can be enlarged into a circular fresh air pipe under the condition of sufficient space. Therefore, switching of different shapes of pipelines needs to be realized through pipeline adapters.

The existing pipeline adapter is a hard pipe, the size of the pipe body is large, the pipe body cannot be bent, the space required by installation is large, the pipeline adapter cannot be suitable for different installation scenes, and the utilization rate is low.

Example one

Referring to fig. 1 to 4, the present embodiment provides a duct adapter, which includes a connection pipe 1, a first communication joint 2, and a second communication joint 3. The first communication joint 2 is arranged at one end of the connecting pipe 1 and is communicated with the connecting pipe 1, and the first communication joint 2 is used for connecting a first air pipe; the second communicating joint 3 is arranged at the other end of the connecting pipe 1 and is communicated with the connecting pipe 1, the second communicating joint 3 is used for connecting a second air pipe, and the radial cross-sectional shapes of the first air pipe and the second air pipe are different;

the first communicating joint 2 and the second communicating joint 3 are used for communicating with the air pipe, so that the reliable connection between the air pipe adapter and the air pipe is guaranteed. In addition, as the radial cross-sectional shapes of the first air pipe and the second air pipe are different, the transition of different cross-sectional shapes can be realized through the air pipe adapter.

The first and

second communication joints

2 and 3 are configured to have the same shape as the opening of the air duct to be connected, for example, when one of the communication joints is used to connect a profile pipe, the shape of the communication joint needs to match the shape of the end opening of the profile pipe, or when the communication joint is used to connect a circular pipe, the communication joint is correspondingly configured to be circular and match the size of the opening of the circular pipe, so as to ensure reliable connection.

On this basis, connecting pipe 1 is because flexible pipe material, consequently can realize buckling at optional position along the pipe extending direction to the size of the contained angle that forms between the open orientation in both ends of messenger's tuber pipe crossover sub changes.

For the connection mode between the air pipe adapter and the air pipe, the connection between the connecting pipe 1 and the air pipe can be realized by matching corresponding connecting parts, and the connecting pipe 1 can be integrally arranged at the end part of the air pipe, so that the installation steps are reduced, and the installation efficiency is improved.
