Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a foldable hair dryer.

2. Background Art

Conventionally, as a foldable hair dryer, one shown in FIG. 1 has been proposed. In the figure,
Reference numeral 1 denotes a main body, to which a handle 2 is bendably connected via a support shaft 3. 4 is a motor, 5 is a fan, and 6 is a heater. The lead wire 7 extends from inside the main body 1 through the bent portion into the handle 2 and is connected to the cord 8. However, as the handle 2 is bent, the lead wire 7 expands, contracts, or bends, and the core wire therein may break, making it impossible to conduct electricity.

[Purpose of invention]

The object of this invention is to provide a hair dryer in which the lead wire does not break even when the handle is repeatedly rotated.

[Disclosure of invention]

In the hair dryer of this invention, a pair of terminals each having a spindle insertion hole are passed through a spindle that rotatably supports the main body and the handle, and a lead wire on the main body side and a lead wire on the handle side are connected to each other. is connected. The support shaft is a cylindrical member that projects integrally with the handle split pieces, and both handle split pieces are fixed with screws. Each pair of terminals and a separator and spring washer disposed between each pair of terminals are tightened between the handle halves.

〔Example〕

An embodiment of this invention is shown in FIGS. 2 to 8. In the figure, reference numeral 10 denotes a cylindrical main body, in which a motor 12 with a fan 11 attached and a heater 13 are built in.
5 is provided. A handle connection piece 16 is integrally provided at the bottom of the main body 10 to project, and a handle 19 is connected to the handle 19 so as to be rotatable around a support shaft 18 inserted into a bearing hole 17 of the connection piece 16. The handle 19 is formed into two parts in the thickness direction. The support shaft 18 is integrally provided on one handle split piece 19A and protrudes from an annular protrusion 20 on the other handle split piece 19B.
The tip is stuck in. The spindle 18 is formed into a hollow shaft, and both handle pieces 1 are connected to each other by a tatu pin screw 21 screwed into the spindle 18 from the other handle split piece 19B.
9A and 19B are fixed to each other. Support shaft 18
A hollow connecting shaft 22 similar to that shown in FIG. is being carried out. A pair of terminals 24 and 25 having a support shaft insertion hole 23 are inserted into the support shaft 18 in an overlapping state, and a ring-shaped insulating separator 26 is interposed between each pair of terminals 24 and 25. . The separator 26 is also inserted through the base end of the support shaft 18 , and the separator 26 at the base end is fitted into the bearing hole 17 of the main body 10 . A wave-shaped spring washer 27 is interposed at a portion where the separator 26 and the terminals 24, 25 overlap, and the terminals 24, 25 are elastically pressed into contact with each other by tightening the tassel pin screw 21. Each terminal 24, 25 has a caulking piece 24a, 2
5a, to which lead wires 28 and 29 are crimped. Two lead wires 28 on the main body 10 side are connected to the motor 12 and the heater 13, and two lead wires are connected to the handle 19.
The side lead wire 29 is connected to a switch 30. Each lead wire 28, 29 is held between a holding protrusion 31 integrally provided on the main body 10 and the handle 19. The switch 30 has a sliding operation button 30a, and is connected to two cords 32 led out from the lower end of the handle 19. code 3
2 is caulked with a cord fastener 33 with the connecting shaft 22 in between. 34 is a simultaneous molding bushing. Note that the handle 19 is provided with a locking projection 35, and the locking projection 35 fits into the recess 36 of the main body 10 when the handle 19 is erected.

Operation When the handle 19 is rotated in the direction of the arrow in FIG.
8 and 29 are held and rotated together with the handle 19 around the support shaft 18, and the terminals 2 overlap each other.
4 and 25 rotate while the contact pressure is maintained by tightening the spring washer 27 and the tuft pin screw 21. Therefore, even if the handle 19 is rotated repeatedly, there is no fear that the core wires of the lead wires 28 and 29 will break. Furthermore, the lead wires 28 and 29 can be easily processed and assembled easily. Furthermore, due to the repulsion force of the spring washer 27, the handle 1
A braking force against the rotation of the handle 19 is also obtained.
It is easy to use as it can be rotated with moderate resistance. The cord 32 is connected to the connecting shaft 22 and the cord stopper 3
3 to prevent the cord from coming off, which allows the cord 32 to be held securely in a small space.

[Effect of idea]

The hair dryer of this invention does not have the problem of breakage of the lead wire even if the handle is rotated repeatedly. In particular, the shaft for rotating the handle is a cylindrical shaft that projects integrally with the handle split piece, and both handle split pieces are fixed with screws. Each pair of terminals and a separator and spring washer disposed between each pair of terminals are tightened between the handle halves. Therefore, the terminal can be rotatably joined by joining the handle split pieces, and the number of parts is small and the structure is simple.
