Problems solved by technology

In this way, when the rotating ring is plastically deformed, the pressure between the ratchet protrusion and the ratchet engaging part is reduced, and the grip may become loose.
[0007] Therefore, if you want to suppress the plastic deformation of the rotating ring, you can consider forming the rotating ring with a more rigid material such as metal such as aluminum, but this becomes disadvantageous in terms of processability and cost

Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 to Figure 14 It is a figure which shows one Embodiment of the hair care device of this invention. Hereinafter, the hair dryer 1 will be described as a hair care device, but the hair care device of the present invention includes other appliances and devices such as a hairbrush. in addition, Figure 1 to Figure 8 Among them, X represents the left, Y represents the front, and Z represents the top.

[0042] Such as figure 1 and figure 2 As shown, the hair dryer 1 has a main body 3 having a hair care function and a handle 5 rotatably connected to a connecting portion 31 of the main body 3 .

[0043] The inside of the main body 3 is formed with the wind tunnel 2 from the air inlet 3a covered by the filter at the rear end (right side in the figure) to the air outlet 3b at the front end (left side in the figure). The fan F housed in the wind tunnel 2 rotates to f...

Abstract

The invention provides a hair care device capable of inhibiting plastic deformation with regard to repetitive bending and deformation of a rotary ring without changing materials of a rotary ring. The hair care device is provided with a control mechanism (4) limiting rotation of a grab handle housing (5Hr) relative to a main body housing (3Hr) respectively at a use position and a folding position. The control structure is provided with a first fastening body (10) and a second fastening body (20), the first fastening body is disposed on a part (main body housing), and is provided with a first protruding part (12) protruding in a direction proportional to a rotary central shaft, the second fastening body can be relatively rotatably disposed on an other part (grab handle housing) relative to the first fastening body, and is provided with a second protruding part (22) freely performing crossover with the first protruding part with crimping of the first protruding part; radial wall thickness (tl) of the first protruding part (10K) disposed on the first fastening body is formed to be higher than radial wall thickness (t2) of other parts (10N).

Description

technical field [0001] The present invention relates to a hair care device in which a handle housing is rotatably connected to a connecting portion of a main body housing. Background technique [0002] In the past, we know a hair care device with the following parts: a main body housing of a main body having a hair care function, a handle housing of a handle rotatably mounted on a connecting portion of the main body housing, respectively in use position and a restraint mechanism that restricts the rotation of the handle case relative to the main body case in the folded position (see, for example, Patent Document 1). [0003] At this time, the structure of the above-mentioned control mechanism includes a rotating ring (first engagement body) that is engaged with a hub portion provided on the main body housing and has a ratchet (click) protrusion (first protrusion) on the outer periphery. ), and the ratchet engaging part (second protruding part) protruding directly on the han...
