[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 In the embodiment of the utility model, a high-speed hair dryer with a foldable handle structure includes a hair dryer body 1 composed of a hair dryer shell 101, a fixing seat 102, a handle 103, and a rotating connection shell 104. The fixing seat 102 is fixed to the bottom of the hair dryer shell 101, the rotating connection shell 104 is symmetrically fixed to the top of the handle 103, the rotating connection shell 104 is symmetrically distributed on the outside of the fixing seat 102 and is rotatably connected to the fixing seat 102, and an L-shaped switch activity groove 1 is opened on the outside of the handle 103. 05, the L-shaped switch movable groove 105 penetrates to the top of the handle 103, a push block 106 is slidably installed inside the L-shaped switch movable groove 105, and a limit top block 107 is fixedly connected to the top of the push block 106. The limit top block 107 protrudes to the top of the handle 103 along the track of the L-shaped switch movable groove 105. When the handle 103 is folded to a state of being 90 degrees vertical to the fixed seat 102, the limit top block 107 is attached to the outer side of the fixed seat 102, which is used to limit and lock the movement of the push block 106;

[0024] A self-locking groove 2 is provided at the bottom of the fixing seat 102. When the handle 103 is rotated to be vertically aligned with the fixing seat 102, the limit top block 107 is located directly below the self-locking groove 2. The self-locking groove 2 is used to provide space for the limit top block 107 to move upward, and the limit top block 107 is inserted into the self-locking groove 2 to lock the rotation of the handle 103.

[0025] A rotating connection assembly 3 is provided between the fixing seat 102 and the rotating connection shell 104 . The rotating connection assembly 3 is used to realize the rotating connection between the rotating connection shell 104 and the fixing seat 102 , and is also used to provide a channel for the installation of the wire.

[0026] In this embodiment, it should be supplemented that: a push switch is installed inside the handle 103, and the push block 106 is connected to the sliding member of the push switch. The push switch can be opened or closed by moving the push block 106 to drive the sliding member of the push switch to move, thereby controlling the power on or off of the hair dryer (it should be noted that the handle 103 is also equipped with a start / stop button and a temperature control button. This is an existing structure, so it is not drawn or elaborated. The push switch corresponding to the push block 106 only controls the power on or off of the hair dryer);

[0027] When the handle 103 is rotated to a state of being 90 degrees vertical to the fixing seat 102, the handle 103 is in a retracted state, and its limiting top block 107 is in contact with the outer side of the fixing seat 102, leaving no space for movement, so that the push block 106 cannot move when the handle 103 is not unfolded or is unfolded, thereby preventing the hair dryer from being accidentally started when the handle 103 is unfolded;

[0028] When the handle 103 is unfolded and rotated to be vertically aligned with the fixing seat 102, the limiting top block 107 is aligned with the locking groove 2. At this time, the pushing block 106 can move up and push the limiting top block 107 to be inserted into the locking groove 2, which not only realizes the power connection operation of the hair dryer, but also fixes the upright state of the handle 103 to ensure stability during use. Similarly, when the handle 103 needs to be rotated and stored, it is also necessary to push the pushing block 106 downward to cut off the power to the hair dryer, and at the same time disengage the limiting top block 107 from the locking groove 2. Such operation can effectively improve the safety of the hair dryer.

[0029] Please refer to Figures 1 to 4 , the rotating connection assembly 3 includes an L-shaped annular groove 302 and a convex annular cylinder 304;

[0030] The L-shaped annular groove 302 is symmetrically formed on both sides of the outer wall of the fixing seat 102, and the convex annular cylinder 304 is fixed to the inner side of the rotating connection shell 104, and the convex annular cylinder 304 protrudes from the outer side of the rotating connection shell 104 and is rotatably connected to the L-shaped annular groove 302, so as to realize the rotatable connection between the rotating connection shell 104 and the fixing seat 102;

[0031] The rotating connection assembly 3 further includes a horizontal through hole 301, a vertical through hole 303, and a threading groove 305;

[0032] The horizontal through hole 301 is formed inside the fixing base 102 and penetrates both sides of the fixing base 102. The horizontal through hole 301 is located inside the L-shaped annular groove 302. The vertical through hole 303 is formed at the top of the inside of the horizontal through hole 301 and communicates with the inner cavity of the hair dryer housing 101.

[0033] The threading groove 305 is formed at the top of the convex annular cylinder 304 and is located inside the rotating connection shell 104;

[0034] The top of the handle 103 is in an open structure and is connected to the inner side of the rotating connection shell 104 , and the L-shaped switch movable groove 105 is connected to the inner cavity of the handle 103 .

[0035] In this embodiment, the power supply wire of the hair dryer can pass through the inner cavity of the handle 103, the inner cavity of the rotating connecting shell 104, the threading groove 305, the inner cavity of the convex annular cylinder 304, the horizontal through hole 301, and the vertical through hole 303 from the bottom of the handle 103 in sequence to enter the interior of the hair dryer housing 101 and connect with the electric wire of the motor inside it;

[0036] Through the threading trajectory of the wire, when the handle 103 is rotated and folded, the wire will only be twisted at a small angle, which is different from the traditional structure in which the wire is directly passed through the middle and bends at a large angle when folded. This can effectively reduce the damage to the wire and extend the service life of the wire.

[0037] Please refer to Figures 1 to 4 The two sides of the horizontal through hole 301 are in a trumpet-mouth structure, the threading groove 305 is distributed inside the rotating connection shell 104 and the inner wall size is larger than the wire diameter, and the distance between the outer wall of the small diameter part of the convex annular cylinder 304 and the inner wall of the rotating connection shell 104 is larger than the wire diameter.

[0038] In this embodiment, this structure allows the wire to easily pass through the wire threading groove 305 and the gap between the convex annular cylinder 304 and the connecting shell 104 .

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
