DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] like Figure 1-6 As shown, it includes a handle 10, a hair dryer body 20 and a folding assembly. The hair dryer body 20 is provided with an air outlet 21, a heater 22, a motor unit 23 and an air inlet 24. The air outlet 21 and the air inlet 24 are detachably mounted on the hair dryer body 20, and a number of through holes are provided on the air outlet 21 and the air inlet 24. All parts of the hair dryer body 20 are on the same central axis, which is convenient for wind to enter the body and take out heat. The heavier motor unit 23 is arranged at the corresponding position of the handle 10, so that its center of gravity is inside the handle 10, avoiding effort for the user. The handle 10 is connected to the outer peripheral side of the hair dryer body 20 through the folding assembly, so that it can be folded together for easy carrying and storage.
[0026] The folding assembly includes a bending block 30, a rotating shaft 33 and a slide plate 36, wherein the bending block 30 is fixed on the hair dryer body 20, the rotating shaft 33 is fixed in the handle 10, the rotating shaft 33 is rotatably connected to the bending block 30, and the slide plate 36 is detachably installed in the handle 10, the slide plate 36 wraps the bending block 30 and is slidably connected to it, wherein a wire cavity 31 is provided in the bending block 30, and a limiting hole 32 is opened on its surface, and a protective hole 37 is opened on the slide plate 36, and the protective hole 37 and the limiting hole 32 are on the same side.
[0027] The main buckle 34 is detachably provided on the side of the bending block 30 away from the limiting hole 32, and the auxiliary buckle 35 is installed in the main buckle 34. The rotating shaft 33 passes through the main buckle 34 and the auxiliary buckle 35, wherein the main buckle 34 is fixed in the bending block 30 through the limit block, and the auxiliary buckle 35 is fixed in the handle 10. The main buckle 34 and the auxiliary buckle 35 rotate relative to each other. The inner wall of the main buckle 34 is provided with at least four slots, and at least two blocks are fixed on the outer peripheral side of the auxiliary buckle 35. The rotation of the blocks in the slots can form a sense of frustration, which can be used to limit the position of the handle 10 so that the handle 10 will not be easily opened after folding, and the sense of frustration can enable the user to understand the current relative position of the handle 10 and the hair dryer body 20 by touch, thereby improving the user experience.
[0028] A circuit board 12 is provided inside the handle 10, and a switch button 11 is also installed on the circuit board 12. The switch button 11 controls the start and stop of the hair dryer. The circuit board 12 has several practical electronic components. A main line 13 is installed at the bottom of the handle 10. The main line 13 is connected to the circuit board 12. Several wires are connected to the circuit board 12. The wires enter the wire cavity 31 through the protective hole 37 and the limiting hole 32, and are connected to the motor group 23 and the heater 22 in the hair dryer body 20. The outer peripheral side of the bending block 30 is an arc surface. The setting is that the slide plate 36 is arc-shaped, and the slide plate 36 slides relatively on the bending block 30. The limiting hole 32 is arc-shaped, and its arc circumference is greater than the arc circumference of the protective hole 37. The arc angle of the limiting hole 32 is 0-90°, wherein the slide plate 36 is connected to the handle 10 and can be used to guide the handle 10, and then the protective hole 37 thereon can drive the wire to move synchronously, which is used to protect the wire and avoid the problem of wire jamming when the handle 10 and the hair dryer body 20 are folded against each other, thereby causing damage to the wire.
[0029] Working principle: One end of the wire inside the handle 10 is connected to the circuit board 12, and then passes through the protective hole 37, enters the limiting hole 32 through the wire cavity 31, and enters the hair dryer body 20 after circling the limiting hole 32 half a circle, and is connected to its internal electronic components. However, when the handle 10 needs to be folded, the handle 10 is directly bent with force so that the handle 10 and the hair dryer body 20 are folded in half. During the bending process, the wire is restricted by the protective hole 37 and slides in the wire cavity 31. At the same time, the rotation of the handle 10 will drive the auxiliary buckle 35 to rotate, and the main buckle 34 is fixed in the bending block 30, so at this time the auxiliary buckle 35 and the main buckle 34 produce relative rotation, and the card block on the auxiliary buckle 35 cooperates with other card slots in the main buckle 34 to achieve the purpose of just completing the folding.
[0030] In summary, the foldable hair dryer can be easy to carry and store through the foldable handle 10 and the hair dryer body 20. The main buckle 34 and the auxiliary buckle 35 can be used to limit the position of the handle 10 so that the handle 10 will not be easily opened after being folded, and the sense of frustration can allow the user to understand the current relative position of the handle 10 and the hair dryer body 20 by touch, thereby improving the user's experience; the slide plate 36 is connected to the handle 10 and can be used to guide the handle 10, and then the protective hole 37 thereon can drive the wire to move synchronously, which is used to protect the wire and avoid the problem of wire jamming when the handle 10 and the hair dryer body 20 are folded against each other, thereby causing the wire to be damaged.
