Problems solved by technology

It is known that the strength and physical properties of such flame-retardant resins are lower than those of ordinary resins.
[0006] Therefore, in the structure in which the ring-shaped rib provided with the first convex part and the second convex part receiving the rotating ring is integrally formed on the handle part like the conventional hair care device, the use of flame-retardant resin improves safety. When the strength of the annular rib is also reduced, there is a possibility that the shape change or breakage may occur in the handle due to the stress generated in the annular rib when the second convex portion passes over the first convex portion.
Especially, in the case of a hair care device having various functions, such a problem becomes remarkable

Embodiment Construction

[0057] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, a hairbrush will be exemplified below as a hair care device. In addition, in Figure 1 to Figure 10 Among them, X represents the left, Y represents the front, and Z represents the top.

[0058] Regarding the hair dryer 1 of the present embodiment, such as figure 1 and figure 2 As shown, there is a handle part 5 as a part held by the user's hand, and a main body part 3 combined with the handle part 5 in a direction intersecting with the handle part 5. The handle 5 and the main body 3 have a substantially T-shaped or substantially L-shaped (substantially T-shaped in this embodiment) appearance. A power cord 7 is drawn out from the protruding end of the handle portion 5 . In addition, the handle part 5 is rotatably connected to the main body part 3 . In addition, the handle portion 5 can be folded to a position along the main body portion 3 .

Abstract

The invention provides a hair care device, which is capable of improving durability of a control mechanism. In the hair care device, the control mechanism (4) is formed by a first fastening body (10) and a second fastening body disposed on a main body housing (3H), the second fastening body (20) is formed by materials with strength higher than grab handle housing (5H), the second fastening body (20) can be relatively movably disposed on the grab handle housing (5H) relative to the first fastening body (10), and is fastened with the first fastening body (10) respectively at a use position and a folded position of the hair care device (1) to limit the grab handle housing (5H) to rotate relative to the main body housing (3H).

Description

technical field [0001] The present invention relates to hair care devices. Background technique [0002] Conventionally, there is known a foldable hair care device in which a handle portion is rotatably coupled to a coupling portion of a body portion in which a wind tunnel portion is formed (for example, refer to Patent Document 1). [0003] In this patent document 1, the rotating ring provided on the boss part formed on the main body part and protrudingly provided with the first convex part on the outer periphery; When the shank is relatively rotated relative to the main body, the ring-shaped rib of the second convex part that is engaged with the first convex part while elastically deforming the rotating ring forms a restraint mechanism. Rotation of the handle portion relative to the main body portion is restricted in the use position and the folded position. [0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2-77207 [0005] In recent years, there ar...
