In some embodiments of the utility model the fresh air duct 1 further comprises a mounting structure 111 extending in the length direction of the first edge 11, the mounting structure 111 protruding from the inner and/or outer surface of the duct wall 10, the mounting structure 111 being in contact with the space wall of the telescopic space when located therein. When the diameter of the new air pipe 1 is manually increased by a user, the first edge 11 is driven to abut against the space wall of the telescopic space when moving towards the opening direction in the telescopic space, so that the first edge 11 is prevented from separating from the telescopic space, and the new air pipe 1 is stable in structure and difficult to leak air due to the arrangement.
Referring to fig. 1, in some embodiments of the present utility model, a clamping structure is disposed at the opening, and the clamping structure is used to prevent the mounting structure 111 from being separated from the telescopic space. Specifically, the engagement structure is provided on a space wall for forming an opening in the expansion space, and the mounting structure 111 abuts against the engagement structure on the space wall of the expansion space.
In some embodiments of the present utility model, the snap-fit mechanism includes a stop bar 121 disposed within the opening, an inner surface of the stop bar 121 being configured to contact the mounting structure 111 to prevent the mounting structure 111 from being disengaged from the telescoping space.
In some embodiments of the utility model, the number of stop strips 121 is two, one on each of two side edges of the opening parallel to the length of the first edge 11. The two stop strips 121 are spaced apart such that there is a gap between the two stop strips 121 such that the first edge 11 can enter the telescoping space from the gap.
When the first edge 11 is in the telescopic space and is close to the opening, the inner surface of the stop strip abuts against the part of the mounting structure 111 protruding from the inner surface and/or the outer surface of the pipe wall 10, so that the first edge 11 is prevented from being separated from the telescopic space, and the arrangement is convenient to operate.
Referring to fig. 2, in some embodiments of the present utility model, the fresh air duct 1 further includes a guide 112 having a gradually decreasing thickness along the insertion direction of the first edge 11, the guide 112 being disposed at the first edge 11. Specifically, the engagement structure is provided on the rear side of the guide portion 112 along the insertion direction of the first edge 11. Since the thickness of the guide portion 112 along the insertion direction of the first edge 11 becomes gradually smaller, the guide portion 112 is easy to enter the expansion space from the opening, and the first edge 11 is driven to enter the expansion space.
In some embodiments of the present utility model, the guide 112 is connected to the mounting structure 111, and the guide 112 and the mounting structure 111 form a single body with a triangular cross section. The mounting structure 111 protrudes from both the inner and outer surfaces of the tube wall 10. Specifically, the base of the triangle is directed towards the first edge 11 and the apex angle of the triangle is arranged towards the second edge 12. This arrangement makes it easy for the first edge 11 to enter the telescopic space and difficult to exit the telescopic space.
Referring to fig. 3, in some embodiments of the present utility model, both the inner and outer surfaces of the tube wall 10 are provided with steel wires 13 to form a layer of steel wires 13 on the inner and outer surfaces of the tube wall 10. Specifically, when the new branch pipe is bent or the outside is extruded, the steel wire 13 layers arranged on the inner surface and the outer surface of the new branch pipe can provide support for the new branch pipe 1, so that the cross section shape of the new branch pipe is guaranteed when the whole pipeline is bent, and the influence of dead bending on the flow of fresh air is avoided.
In some embodiments of the present utility model, the tube wall 10 includes a first tube wall region 101 having a first edge 11 and a second tube wall region 102 having a second edge 12. The thickness of the first tube wall region 101 becomes progressively greater from the first edge 11 towards the second edge 12.
In some embodiments of the present utility model, the thickness of the second tube wall region 102 is gradually increased from the first edge 11 toward the second edge 12, such that the thickness of the tube wall 10 is gradually increased from the first edge 11 toward the second edge 12. In some alternative embodiments, the thickness of the second tube wall region 102 is constant.
That is, the pipe wall 10 near the first edge 11 is thinner, the pipe wall 10 near the second edge 12 is thicker, and when the first edge 11 enters the expansion space, the pipe wall 10 near the first edge 11 overlaps with the pipe wall 10 near the second edge 12, and the difference between the thicknesses of the pipe wall 10 near the first edge 11 and the pipe wall 10 near the second edge 12 makes the difference between the thicknesses of the overlapping parts smaller than the thickness of the pipe wall 10 at other parts of the pipe wall 10, thereby reducing the influence of the overlapping parts on ventilation of the fresh air duct 1.
In some embodiments of the present utility model, the structure of the pipe wall 10 for defining the expansion space and the inner surface of the pipe wall 10 is that the pipe wall 10 is spaced, and the thickness of the pipe wall 10 is gradually increased from the opening from the second edge 12 to the first edge 11 to the preset position, so that the thickness of a part or all of the area of the pipe wall 10 is gradually increased, so that no step is formed on the inner wall of the fresh air pipe as much as possible, the air supply smoothness is improved, and the air supply noise is reduced.
The utility model also provides an indoor unit of an air conditioner, which comprises the fresh air pipe 1 in any embodiment.
