[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] See also Figures 1 to 6 As shown, the utility model is an air inlet net rotating structure, comprising a hair dryer body 1, and an air inlet net 2 connected with the hair dryer body 1; the hair dryer body 1 is provided with an air inlet 3 and an air outlet 4, the air inlet net 2 cover is arranged at the air inlet 3 and is rotatably engaged with the hair dryer body 1; the air inlet net 2 is a cylindrical structure, and a baffle 18 is arranged at one end of the air inlet net 2 away from the hair dryer body 1, and the baffle 18 is used for limiting the contact with the hair dryer body 1; a buckle structure that can be engaged with each other is distributed between the hair dryer body 1 and the baffle 18, and a rotation-stopping rib 13 that cooperates with the hair dryer body 1 to limit the rotation of the air inlet net 2 is arranged on the buckle structure. The utility model provides a buckle structure that can be engaged with each other between the hair dryer body 1 and the air inlet net 2, and the baffle 18 contacts the hair dryer body 1, and the air inlet net 2 can be installed and removed blindly, which is more convenient to use, has a reliable structure, is easy to clean, and has a longer service life.

[0031] During installation, the air inlet net 2 is covered on the hair dryer body 1, and the air inlet net 2 rotates circumferentially along the air inlet 3 and is engaged with the hair dryer body 1 via the snap-fit ​​structure, so that the air inlet net 2 is movably installed on the hair dryer body 1. When the air inlet net 2 needs to be removed, it only needs to be rotated in the opposite direction to separate the engaged snap-fit ​​structure, and then the air inlet net 2 can be removed.

[0032] In a further technical solution, the air inlet net 2 is provided with a plurality of first mesh holes 20 penetrating through the wall of the air inlet net 2. The first mesh holes 20 are used for primary filtering to prevent large particles of dust and hair from entering the hair dryer.

[0033] In a further technical solution, the hair dryer body 1 is provided with an air inlet inner filter 17, which is placed in the air inlet net 2 and covered on the air inlet 3, and the air inlet metal cover is provided with a second mesh 21 penetrating the air inlet metal cover, and the diameter of the second mesh 21 is smaller than the diameter of the first mesh 20. The second mesh 21 is used for further filtering to prevent small particles of dust from entering the hair dryer.

[0034] The buckle structure includes an avoidance position 5, a clamping position 6, and a clamping part 7. One of the hair dryer body 1 and the air inlet net 2 is provided with the avoidance position 5 and the clamping position 6, and the other is provided with the clamping part 7. The clamping part 7 enters the clamping position 6 through the avoidance position 5. The clamping part 7 is installed in cooperation with the clamping position 6 via the avoidance position 5, so that the air inlet net 2 is movably installed on the hair dryer body 1, and the air inlet net 2 is quickly installed and removed. The avoidance position 5 and the clamping position 6 are adjacently distributed in the circumferential direction of the air inlet 3, so that the air inlet net 2 can be buckled into the hair dryer body 1 by rotating a small angle, which is convenient and quick.

[0035] The hair dryer body 1 is provided with an annular mounting groove 8 at one end close to the air inlet 3. The mounting groove 8 is formed by being recessed from the outer wall of the hair dryer body 1 along the circumference of the air inlet 3. The clamping position 6 is located in the mounting groove 8. The avoidance position 5 is an opening on the side of the mounting groove 8 close to the air inlet 3. The clamping part 7 extends from the avoidance position 5 and rotates circumferentially to the clamping position 6, so that the air inlet net 2 can be detachably mounted on the hair dryer body 1. After the air inlet net 2 is installed, the avoidance position 5, the clamping position 6, and the clamping part 7 are hidden in the mounting groove 8, and the contact area between the air inlet net 2 and the hair dryer body 1 is increased, which is used to further limit the air inlet net 2 and enhance the structural stability.

[0036] The clamping position 6 is provided with a protruding portion 9 protruding from the side wall of the installation groove 8, and the protruding portion 9 is provided with a limiting groove 10 for accommodating the clamping portion 7.

[0037] The clamping portion 7 is provided with a clamping slot 11, which extends along the circumference of the air inlet 3. A limiting protrusion 12 cooperating with the limiting groove 10 is provided in the clamping slot 11, and the anti-rotation rib 13 is adjacent to the limiting protrusion 12 along the circumference of the air inlet 3. When the air inlet net 2 is installed, the protrusion 9 extends into the clamping slot 11, and the limiting protrusion 12 cooperates with the limiting groove 10 to further limit the position of the air inlet net 2 and enhance the structural stability; the anti-rotation rib 13 is used to limit the rotation of the air inlet net 2 to prevent the limiting protrusion 12 from sliding out of the limiting groove 10 when the air inlet net 2 rotates too much.

[0038] The buckle structure is provided with two groups, and the two groups of buckle structures are symmetrically distributed around the central axis of the air inlet net 2. The two groups of buckle structures increase the clamping position 6 between the air inlet net 2 and the hair dryer body 1, and improve the installation stability of the air inlet net 2.

[0039] The end of the protrusion 9 close to the avoidance position 5 is provided with an angled section 14, which facilitates the clamping portion 7 of the air inlet net 2 to enter smoothly in the forward direction. The angled section 14 guides the sliding direction of the limiting protrusion 12, so that the limiting protrusion 12 slides into the limiting groove 10 more smoothly, which saves more effort and makes the disassembly and assembly of the air inlet net 2 more convenient.

[0040] The limiting groove 10 is provided with a first chamfer 15, which facilitates the smooth reverse removal of the air inlet net 2. The first chamfer 15 facilitates the limiting protrusion 12 to slide out of the limiting groove 10 more smoothly, saving more effort and making the disassembly and assembly of the air inlet net 2 more convenient.

[0041] The limiting protrusion 12 is provided with a second chamfer 16, which facilitates the smooth rotation of the air inlet net 2. The second chamfer 16 facilitates the limiting protrusion 12 to slide out or slide into the limiting groove 10 more smoothly, making the disassembly and assembly of the air inlet net 2 more convenient.

[0042] The hair dryer body 1 is provided with a mounting member 19, which is detachably connected to the hair dryer body 1. The air inlet net 2 is rotatably engaged with the hair dryer body 1 via the mounting member 19, and the buckle structure is connected to the hair dryer body 1 via the mounting member 19. The detachable connection between the mounting member 19 and the hair dryer body 1 facilitates replacement of the mounting member 19, thereby solving the problem that the buckle structure is difficult to replace due to wear and damage caused by long-term use.

[0043] In a further technical solution, the outer surface of the air inlet net 2 is a convex arc surface that rises away from the hair dryer body 1, so that more ventilation holes can be set on the convex arc surface, which can increase the air inlet area of ​​the air inlet 3, thereby reducing the air flow velocity at the air inlet 3, which is conducive to reducing the possibility of noise generated by excessive air flow velocity at the air inlet 3. At the same time, all ventilation holes are arranged on the convex arc surface, and the airflow flowing to the ventilation holes can slide along the convex arc surface to each air inlet 3, which can reduce the noise generated by the collision of the air intake airflow with the convex arc surface and the turbulence of the airflow.

[0044] In a further technical solution, the inner air inlet filter 17 is detachably connected to the hair dryer body 1, so that it is easy to disassemble and replace the inner air inlet filter 17 and to clean and maintain it.

[0045] When installing the air inlet net 2, first place the air inlet net 2 cover at the air inlet, and make the clamping part 7 extend into the avoidance position 5, then rotate the air inlet net 2 counterclockwise or clockwise to make the clamping part 7 move from the avoidance position 5 to the clamping position 6, when the protrusion 9 contacts the anti-rotation rib 13, the limiting protrusion 12 slides into the limiting groove 10, and the air inlet net 2 can be fixedly installed. When the air inlet net 2 needs to be removed, it only needs to rotate the air inlet net 2 in the opposite direction, so that the clamping part 7 moves from the clamping position 6 to the avoidance position 5, and the limiting protrusion 12 slides out of the limiting groove 10, and the back cover can be removed.

[0046] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
