Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair curl device in which an attachment is detachably attached to a main body capable of blowing air, and in particular, an electric component to which power is supplied to the attachment from the main body side. The present invention relates to a hair curling device. As a hair curling device comprising a main body capable of blowing air and an attachment equipped with electric parts and detachably attached to a blower opening of the main body, JP-A-55-12.
There is one disclosed in Japanese Patent No. 5806. The attachment with a built-in heater for auxiliary heating has a pair of connection pins protruding from the end on the side of connection with the main body, and when the attachment is connected to the blower opening of the main body, it is provided on the periphery of the blower opening. Power is supplied from the main body side to the heater by inserting and connecting the connection pins to the pair of connection jacks. In the above-mentioned electrical connecting portion, a pair of connecting pins are arranged at a position 180 degrees apart from one end of the attachment, and a pair of connecting jacks have a blower port of the main body. Since it is provided on one end face, it has the following problems. First, since a pair of connection jacks to which a pair of connection pins are connected are located on both sides of the main body, internal wiring must be routed to both sides of the main body.
In addition to the difficulty of wiring work, each wiring portion increases the ventilation resistance. Secondly, since the connection jack is arranged on one end surface of the main body where the air outlet is provided, the air outlet is narrowed due to the connection jack, resulting in a large air loss. Of course, if the connection jack is provided so as to project outside the main body, air loss will be reduced, but the appearance of the main body will be large. Furthermore, when connecting the main body and the attachment, it is necessary to connect while looking at both of the pair of connecting portions separated from each other on both sides, which makes it difficult to connect the main body and the attachment. The present invention has been made in view of the above circumstances, and an object thereof is to prevent the electrical connection between the main body and the attachment from causing a blowing loss, and further, to prevent the main body from being blown. It is to provide a hair curling device that does not make connection work with the attachment difficult. SUMMARY OF THE INVENTION The present invention, however, comprises a main body having blower means built therein and an attachment detachably attached to the blower opening of the main body, and the connection end portion between the main body and the attachment is formed. Is provided with an electrical connection portion including a pair of connection pins and a connection jack.
The attachment is a heater that is supplied with power from the body side.
A hair curling device provided in the center of the inside, characterized in that a pair of connection pins arranged in proximity and a pair of connection jacks arranged in proximity are arranged on the outer peripheral side of the blower opening. . Since the pair of connecting pins and the pair of connecting jacks are arranged close to each other, the internal wiring can be gathered and the portion which becomes a ventilation resistance can be reduced.
Further, since it is arranged on the outer peripheral side of the blower opening, the opening area of the blower opening does not become small. The main body and the attachment are provided with a fitting tubular portion that fits to each other at the connection portion, and the connection jack provided on the main body is provided on the attachment with the opening facing the rear end side of the fitting tubular portion. When the connecting pin projects from the front end of the fitting tubular portion, it is preferable that the fitting tubular portions are fitted together as a guide when the connecting pin and the connection jack are connected.

A pusher 37 is installed between the fixed plate 35 and the holding body 41 and presses the holding body 41 to the inner side of the holder 31 via a spring 38 by a screw 36 screwed to the fixed plate 35. It is arranged. Because of the wedge shape, the electrical contact between the electrode plate 43 and the heat generating member 30 and the heat contact between the heat generating member 30 and the holder 31 are reliably maintained. Is. As shown in FIG. 5, the connecting member 13 attached to one end of the body 1 has ribs in which a large-diameter cylindrical portion 13a and a small-diameter cylindrical portion 13b are axially spaced from each other. 1
It has a shape connected by 3c, and a small-diameter cylindrical portion 13b is fixed to the body 1. A pair of connecting pins 48a and 48b, to which the lead wires 44 drawn out from the electrode plates 43 and 43 are connected, project from the end surface of the large-diameter cylindrical portion 13a. The water supply member 2 arranged at the other end of the body 1 is arranged in the tank case 21, a cylindrical cylindrical portion 22 which is detachable from the tank case 21, and the cylindrical portion 22. The water absorbent body 20 and the tank case 21 are provided with a valve 24 for adjusting the internal pressure.
A seal 23 is arranged on the outer peripheral surface of the cylindrical portion 22 to be inserted therein, and a projection 26 for preventing slipping out is provided in a protruding manner. The water absorbent body 20 having one end located inside the water supply member 2 has the other end located on the inner surface of the V-shaped notch formed on the tip surface of the tubular portion 22. A projection 2 is formed on a cap 16 which is rotatably held by a cylinder 15 screwed to the tip of the body 1.
The water supply member 2 which is prevented from coming off from the body 1 by engaging 6 is attached in the direction away from the heater 3 by the spring 25 whose one end is held by the projection 32 on the tip surface of the holder 31 of the heater 3. Therefore, the water absorbing body 20 of the water supply member 2 faces the outer surface of the heater 3 as shown in FIG. 2, but is kept in a non-contact state. However, if the water supply member 2 is pushed in against the spring 25, the outer surface of the heater 3 and the inner surface of the water absorbing body 20 come into contact with each other, as shown in FIGS.
When 0 heats up, the holder 31, which is heated by this heat, heats the water contained in the water absorbing body 20 into steam, which is used as the groove 33 and the small hole 10 provided in the body 1.
