Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 6, an embodiment of the present invention provides an air duct, including an inner tube 2 and an outer sleeve 1, a fixing hole 21 is provided on a side wall of the inner tube 2, a fixing portion 11 is provided on an inner wall of the outer sleeve 1, when the outer sleeve is disposed on an outer wall of the inner tube 2, the fixing portion 11 is inserted into the fixing hole 21, the fixing portion 11 includes a deformable protruding portion 111, and a width of the protruding portion 111 is greater than a width of the fixing hole 21; the projection 111 is press-inserted through the fixing hole 21 with force, and the projection 111 is stuck against the inner wall of the inner cylinder 2, which is clamped by the projection and the inner wall of the outer sleeve. The inner cylinder 2 is clamped by the protruding part 111 and the inner wall of the outer sleeve 1, so that the outer sleeve 1 of the air duct is good in wrapping effect, and the outer sleeve 1 cannot be loosened when the air duct is used.
Specifically, the fixing portions 11 are bar-shaped, each fixing portion 11 is arranged along the axial direction of the jacket 1, and the plurality of fixing portions 11 are uniformly distributed on the inner wall of the jacket. The fixing parts 11 are uniformly distributed, so that the installation stress is ensured to be even, and the outer sleeve 1 is not easy to twist and separate.
Specifically, the protrusion 111 is disposed at one end of the fixing portion, and has an i-shaped cross section. The clamping of the inner cylinder wall can be realized.
Further, two ends of the outer wall of the outer sleeve 1 are respectively provided with an annular bulge 12, the annular bulge 12 can play a role in stabilizing the structure, and meanwhile, the purpose of increasing the handheld friction force can be achieved in the dismounting process.
Further, the end of the jacket 2 is provided with a raised rim 22 for preventing the jacket 1 from slipping out.
The utility model also provides a hair-dryer, including above-mentioned dryer.
The embodiments in the present specification are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
