Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to an adjustable fabric air duct. Background Art

[0002] The creation of indoor environment plays a vital role in human comfort and health. People's attention to indoor environment is no longer limited to comfort, but also puts forward requirements for indoor air quality. Various air-conditioning equipment and air supply forms have also emerged. Fiber fabric air duct is one of the new air supply systems; fiber fabric air duct is an air flow distribution system woven from fiber fabric. It is not only a fiber fabric pipe or fiber fabric air duct, but also shoulders the role of air flow evacuation. It is a flexible mixing device suitable for air flow distribution and system air supply in air-conditioned rooms. The fiber fabric air distributor has a high degree of integration and is a terminal device that integrates air duct and air material.

[0003] However, in some places where the air volume needs to be changed and adjusted, the diameter and air supply volume of the existing fiber fabric air duct cannot be flexibly adjusted accordingly. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable fabric air duct to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable fabric air duct, comprising an air duct body, one end of the air duct body is provided with an air inlet, the other end of the air duct body is connected to a plug, and a ventilation hole is provided on the air duct body; the air duct body is also provided with a first connecting part and a plurality of second connecting parts with the same structure; the first connecting part is connected to the farthest second connecting part to minimize the diameter of the air duct body; the first connecting part is connected to the nearest second connecting part to maximize the diameter of the air duct body.

[0018] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: an adjustable fabric duct, comprising a duct body 2, one end of the duct body 2 is provided with an air inlet 1, and the other end of the duct body 2 is connected to a plug 7, and a ventilation hole 4 is provided on the duct body 2; the duct body 2 is also provided with a first connecting portion 5 and a plurality of second connecting portions 6 with the same structure; the first connecting portion 5 is connected to the farthest second connecting portion 6 to minimize the diameter of the duct body 2; the first connecting portion 5 is connected to the nearest second connecting portion 6 to maximize the diameter of the duct body 2.

[0020] In summary, by connecting the first connection part 5 with the second connection part 6 at different positions, the diameter of the air duct body 2 can be adjusted, thereby adjusting the air volume. Based on this, when the air enters the air inlet 1, because there is a plug 7 at the end, the air can only be discharged from the ventilation hole 4; by connecting the first connection part 5 with the corresponding second connection part 6, the diameter of the air duct body 2 can be adjusted to adjust the air supply volume; so that the device can adapt to places where the air volume needs to be changed and adjusted.

[0021] In addition, when the first connection part 5 on the surface of the air duct body 2 is connected to the second connection part 6 at a different position, the diameter of the air duct body 2 can be adjusted. When the air volume changes, it can be adjusted accordingly to avoid the mismatch between the diameter of the air duct body 2 and the air supply volume and the fan when the fan adjusts the air volume.

[0022] Furthermore, since the first connection portion 5 and the second connection portion 6 are both arranged in the length direction of the air duct body 2, the diameter of the entire air duct body 2 is unified after adjustment, thereby avoiding bulging due to inconsistent diameters after air enters the air duct body 2.

[0023] Furthermore, since the first connection part 5 and the second connection part 6 are zippers, the connection or separation of the first connection part 5 and the second connection part 6 is completed by the provided zipper head 10. Therefore, the diameter of the duct body 2 can be easily adjusted while reducing the use cost of the two connection parts, and the zipper can be easily sewn on the duct body 2, so that the diameter adjustment is simpler and more convenient. Specifically, when the first connection part 5 is a male zipper, the second connection part 6 is a female zipper.

[0024] Based on the above scheme, since air outlets 9 are provided between the first connection part 5 and the second connection part 6 and between two adjacent second connection parts 6, the air outlets 9 can be used to adjust the internal air pressure of the air duct body 2 to extend the service life of the air duct body 2.

[0025] Based on this, when the air volume decreases, the first connection part 5 and the second connection part 6 are closed, the diameter of the air duct body 2 is shrunk, and part of the air outlets 9 are stored inside the air duct body 2, thereby reducing the number of air outlets 9 and preventing the rear section of the air duct body 2 from being windless.

[0026] When the air volume increases, the first connection part 5 and the second connection part 6 are opened to expand the diameter of the duct body 2, prevent the wind speed in the duct body 2 from being too high, reduce wind resistance, increase the number of air outlets 9, prevent the air flow from being squeezed in the pipe, effectively reduce the pressure in the pipe, and delay the service life of the fabric duct.

[0027] Furthermore, since the air duct body 2 is also provided with a hook 3, it is convenient to hang the air duct body 2 on the wall.

[0028] In addition, since the plug 7 is connected to the duct body 2 through the connector 8, a plug 7 of a suitable diameter can be selected according to the diameter of the duct body 2; wherein the connector 8 is preferably a zipper. Thus, the device can better adapt to places where the air volume needs to be changed and adjusted.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
