Description

[Detailed description of the invention] The present invention relates to the case body of a hair dryer, and in particular, the case constituting the outer shell of the hair dryer body is formed into a nearly symmetrical shape from a molded synthetic resin material, and the left and right cases are mutually connected to each other. The present invention relates to an improved structure of a hair dryer in which, after abutting, a cap body is fitted and fixed to one end side of the cap body to form a rod-shaped case body.

The outer shell of this type of dryer body, which is rod-shaped, is generally made of a molded synthetic resin material. The two cases are integrated by forming a hook piece on one case and a hook receiving piece on the other case so that the cases mesh with each other, and a cap body is attached to each end of the rod-shaped body. The assembly is completed by covering the cap body and fixing it to the rod-shaped body by passing a screw or the like through the cap body.

Fixing such a cap body with screws not only unnecessarily increases the number of parts but also complicates assembly man-hours, which is not suitable for mass production.

The present invention has been devised in view of this point, and an embodiment of the present invention will be described below with reference to the drawings. 1 is a long rod-shaped body of a hair dryer commonly called a curl dryer, and a heating element 2 is provided in the internal space. An electric blower 3 for blowing air to the heating element is installed inside, and by energizing these, outside air is sucked in from an air intake port 4 formed at one end, and hot air is discharged from an outlet 5 opened at the other end. I have to.

Reference numeral 6 is a switch attached to the outer surface of the rod-shaped main body 1 to control energization of the heating element 2, electric blower 3, etc., and is electrically connected to a power cord 7 introduced from the one end side.

Reference numeral 8 denotes a brush body which can be attached to and detached from the discharge port 5, and is used when curling the hair or the like.

The outer shell of the rod-shaped main body 1 is made of a molded synthetic resin material, and consists of a left case 9 and a right case 9' that can be divided into left and right parts along the axis. As shown in FIG. 7, for example, hook pieces 11, 11 are formed on the left case 9 side, and hook receiving pieces 12, 12 are provided on the right case 9' side, so that the left and right cases 9, By abutting 9', the hook piece 11 and the hook receiving piece 12 are engaged and locked.

The power cord 7 provided on one end side of the rod-shaped main body 1
A rod-shaped main body 1 is provided at the introduction part of the main body 1 to enclose the power cord 7.
A cylindrical portion 13 having a diameter smaller than that of the cylindrical portion is formed as a guide, and an annular groove 14 is carved on the inner surface of the cylindrical portion so that the power cord 7 can freely rotate along the annular groove 14. There is.

Reference numeral 15 denotes a cap body which is fitted around the outer periphery of the cylindrical portion 13 and holds the cylindrical portion 13 so that it does not separate into left and right sides.

For example, the outer wall 16 of the cylindrical portion 13 on the right case 9' side has a fitting groove 17a extending along the length direction and a bending groove 17b that bends slightly in the circumferential direction at the inner part of the fitting groove. The cylindrical portion 13 has different height dimensions H and H' at the base 18 and at the abutting surface 10 of both cases.

That is, the height H of the part facing the deep part of the fitting groove 17a is made smaller, and the height H' of the part facing the bending groove 17b is reduced.
Notches 19, 19' with larger sizes are provided, and by abutting these left and right cases 9, 9', the notches 19, 19' are enlarged.
19' forms a stepped opening 20.

The cap body 1 is fitted over the cylindrical portion 13.
5 has the fitting groove 17a and the bending groove 17b on its inner surface.
A protruding piece 21 that can be inserted into the cap body is formed, and an elastic tongue piece 22 is formed at the open end of the cap body, projecting forward and slightly bent outward, so that the cylindrical part 13 is attached to the root part 18. It can be inserted into a stepped opening 20 formed therein.

In such a configuration, after the left and right cases 9, 9' are brought together, the cap body 15 is made to face the cylindrical body 13 as shown in FIG. After fitting, the elastic tongue piece 22 of the cap body 15 is inserted by pressing the elastic tongue piece 22 bent outwardly inward in order to insert the elastic tongue piece 22 into the stepped opening 20.

When the cap body 15 is rotated in one direction, the protruding piece 21 is located at the inner part of the bent groove 17b, and the elastic tongue piece 22 is also located at the side of the notch 19, which is larger in height, in the stepped opening 20. At the same time, the elastic tongue piece 22 is elastically returned to the outside and is locked in the stepped opening 20, completing the assembly.

Conversely, during disassembly, the elastic tongue piece 22 of the cap body 15 is pressed with a tapered tool such as a pin, and then rotated a little, so that the elastic tongue piece 22 moves into the notch 19' having a small height dimension. After that, by pulling out the cap body 15, the rod-shaped body 1 is removed.
separated from

Of course, in order to divide the rod-shaped main body 1 into left and right, the left and right cases 9
, 9' and apply force in the separation direction, the engagement between the hook piece 11 and the hook receiving piece 12 is forcibly released and separated.

As described above, the hair dryer of the present invention has a rod-shaped main body that is equipped with a heating element and an electric blower, and has a suction port at one end and a discharge port at the other end, and is divided into a left case and a right case. In the hair dryer, the left and right cases are connected by fitting a cap body over a cylindrical portion formed by a small diameter and extending along the length direction on the outer wall of the cylindrical portion and at a deep portion. A bending groove that can be slightly bent in the circumferential direction is carved at the base of the cylindrical part, and on the extension line of the outer wall of the cylindrical part that spans the left and right cases. A stepped opening is formed by cutouts having different heights, and a protruding piece that engages with the bending groove is inserted into the inner surface of the cap body, and into the stepped opening at the open end of the cap body. When assembling, the cap body is fitted with the cylindrical body with its protrusion along the fitting groove, and the protrusion is inserted into the bending groove by pressing and rotating. , and the elastic tongue piece is located within the notch having a small height dimension and the notch having a large height dimension.

Therefore, tools such as a screwdriver are not required, and the number of parts is minimized, making it possible to provide a practical hair dryer suitable for mass production at low cost.
