DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a blower and a main body having a built-in heater.
The present invention relates to a foldable hair dryer having a grip rotatably connected thereto, and more particularly to a structure of a rotary connection portion thereof.

[Prior art]

In foldable hair dryers, the grip is rotatably connected to the main body.
Some of them take the form shown in FIG. In the figure, reference numeral 10 denotes a connecting portion protruding from the main body 1 containing a blower and a heater, and a boss 13 is protruding from one side surface thereof. 3 is attached. The click body 3 has protrusions 30, which engage with a pair of notches 14, 14 formed on the boss 13, protruding from the inner peripheral surface. The click body 3 is detented. On the other hand, the grip 2 has a housing which is divided into left and right housings 25 and 26 in the direction of the rotation axis, and has a boss for screwing from the inner surface of one end of one housing 26.
27, and from the inner surface of the other housing 25,
A cylindrical shaft 40 and an annular rib 28 are provided to protrude. The boss 27 protruding from the housing 26 is connected to the connecting portion of the main body 1.
10 through one side, and the cylindrical shaft 40 of the other housing 25 is fitted into the other side of the connecting portion 10 to form a cylindrical shaft.
The body 1 and the grip 2 are connected by screwing the tightening screw 41 into the boss 27 from the side of the cylinder shaft 40 with the 40 positioned inside the boss 13. Click protrusion 31 formed on the outer peripheral surface of
And a click engagement portion 29 formed on the inner peripheral surface of the rib 28.
With this engagement, a click is given to the rotation of the grip 2 with respect to the main body 1. A detent projection 45 projecting from one side surface of the connecting portion 10 is located in an annular groove 46 on the outer peripheral side of the rib 28 in the housing 25 of the grip 2, and a detent 47 that partitions the groove 46. , The rotation range of the grip 2 with respect to the main body 1 is regulated.

[Problems to be solved by the invention]

In this case, since the member for regulating the rotation range is on the outer peripheral side of the click body, the connecting portion between the main body and the grip is necessarily increased, and there is a problem that it is difficult to form a small grip. If the size of the click body is reduced to reduce the size, a reliable click cannot be obtained. The present invention has been made in view of such a point, and an object of the present invention is to make sure that a click is given and to reduce a connecting portion between a main body and a grip, so that a small and easy-to-grip is possible. It is an object of the present invention to provide a foldable hair dryer from which a grip can be easily obtained.

[Means for Solving the Problems]

Thus, in the present invention, a grip is rotatably connected to a main body provided with a blower and a heater, and a cylindrical bearing boss protrudes from a side surface of a connecting portion provided on the main body. A stopper is protruded from the tip of the boss, and a ring-shaped click body engaged with and fixed to the boss is disposed on the outer periphery of the boss, and on the inner surface of the grip divided in the axial direction of the rotating shaft, A shaft portion that fits with the boss and a click engaging portion that engages with a click projection that is integrally provided from the click body, and is gripped with respect to the main body by engagement with a stopper at the tip of the boss. It is characterized in that a projection for restricting the rotation range of is formed on the inner surface of the grip at the root of the shaft. [Operation] According to the present invention, it is possible to perform a detent that restricts the rotation range on the inner peripheral side, not on the outer peripheral side of the click body that gives a click for the rotation of the grip with respect to the main body. EXAMPLES The present invention will be described below in detail based on the illustrated examples. As shown in FIGS. 2 to 4, the hair dryer includes a blower including a motor M and a fan F and a main body 1 in which a heater H is disposed, and a connection protruding from the main body 1. A grip 2 whose one end is rotatably connected to the part 10 has a cylindrical nozzle cover 19 attached to the discharge port side at the tip of the main body 1, and the suction port side at the other end of the main body 1. Has a filter 18 attached thereto. The grip 2 has a main switch button 21 of a push button type disposed on the front surface thereof, and a main switch 22 which is switched by the main switch button 21 is mounted inside the grip 2. Has been pulled out. In this hair dryer, the switches 16, 17 are also provided on the front side of the connecting portion 10.
Is attached. The main switch button 21 switches off and switches the amount of heat of the heater, the switch 16 switches the amount of air, and the switch 17 switches on and off the heater. The main body 1 has a housing which is divided in the left-right direction and includes a housing 11 and a housing 12, and a connecting portion 10 is also formed of the two housings 11, 12, and one side of the connecting portion 10 As shown in FIGS. 5 and 6, a boss 13 is protrudingly provided. The boss 13 has two notches 14, 14, and a portion sandwiching the notch 14 is formed as a stopper 15, 15, which protrudes more than other portions. In the figure, reference numeral 3 denotes a click body, and this ring-shaped click body 3 has a pair of engaging projections 30, 30 integrally projecting from the inner peripheral surface thereof, and a click projection 31 integrally from the outer peripheral surface thereof. And is fitted on the outer periphery of the boss 13 of the connecting portion 10 of the main body 1. At this time, a pair of engaging projections
Numerals 30 are located in the cutouts 14 of the boss 13 to prevent rotation of the main body 1, and the click body 3 extends between the inner peripheral surface of the click body 3 and the outer peripheral surface of the boss 13. A void is formed to allow On the other hand, the grip 2 has a housing divided into left and right housings 25 and 26 in the direction of the rotation axis, and an inner surface of one end of one of the housings 26 having an arc-shaped cross section is shown in FIG. Boss for screw tightening as shown in)
27 are protruding. As shown in FIGS. 1, 5 and 7, a cylindrical shaft 40 and an annular rib 28 surrounding the cylindrical shaft 40 protrude from the inner surface of one end of the other housing 25. In addition, in the dead space at the root of the cylinder shaft 40,
A pair of fan-shaped projections 42 are formed. As shown in FIG. 1, the boss 27 protruding from the housing 26 is passed through the connecting portion 10 of the main body 1 from one side, and the cylindrical shaft 40 of the other housing 25 is connected to the connecting portion.
10, the fastening screw 41 is screwed into the boss 27 from the cylinder shaft 40 while the tip of the boss 27 is positioned in the cylinder shaft 40 fitted in the boss 13. By
The main body 1 and the grip 2 are connected. The rotation of the grip 2 with respect to the main body 1 is achieved by the click projection 31 of the click body 3 and the rib of the grip 2.
A click is given at a required rotational position by engagement with a click engagement portion 29 formed on the inner peripheral surface of the inner peripheral surface of the boss 13. By engaging with the stoppers 15, 15 projecting more than 3, the rotation range is restricted. Fig. 1 (a)
Α in the figure indicates the rotation range.

【The invention's effect】

As described above, in the present invention, the rotation range of the grip with respect to the main body is restricted in the dead space on the inner peripheral side of the click body for causing a click at a required rotation position in this rotation. As compared with the conventional example in which a member for restricting the rotation range is provided on the outer peripheral side of the member for applying the click, the size can be reduced, and the size of the click body can be reduced. Therefore, a reliable click can be given, and a small and easy-to-grip grip can be obtained without difficulty.
