[0001]
BACKGROUND OF THE INVENTION
The present invention is a hair treatment that is performed by rotating a heater in order to irradiate the entire hair with infrared rays in hairdressing and beauty, when drying at the time of hair washing, promotion at the time of dyeing, permanent hair or waving the hair. The present invention relates to an improvement of a rotating power feeding device for feeding power to the rotating heater.
[0002]
[Prior art]
A conventional example of this type is disclosed in Japanese Patent Publication No. 4-645 filed by the present applicant. In this technology, a heater that emits infrared rays is attached to a reflector, and the reflector is rotated by a motor so that infrared rays are emitted along the top, rear, and both sides of the subject's head. There was a device.
[0003]
An example of a power feeding device for energizing the heater is shown in FIG. This power supply apparatus includes a brush support plate a that is rotated by a motor for rotating the reflector, a plate spring b that is an arch-shaped movable electrode plate having a central portion attached to the brush support plate a, and the plate It is composed of a brush b ₁ which is a sliding metal bonded to both ends of the spring b and a ring-shaped fixed electrode c which is in sliding contact.
[0004]
Here, d is a lead wire connected to the brush b, and e is a lead wire connected to the fixed electrode c. At least two leaf springs b and fixed electrodes c are attached.
[0005]
When the motor is rotated to rotate the reflector, the conventional power feeding device configured as described above rotates because the leaf spring b is also rotated and the brush b ₁ slides on the fixed electrode c. The power is supplied from the side to the fixed side, and thus the heater is energized.
[0006]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional example, since the spring plate b is used as the movable electrode plate, heat is generated when a current flows through the plate spring b, and the spring constant changes, so that contact failure occurs during long-term use. There was a problem such as causing.
[0007]
Further, if the leaf spring b is directly slidably contacted with the fixed electrode c, the life due to wear is shortened. Therefore, it is necessary to fix a sliding metal different from the leaf spring b with an adhesive. Alternatively, the spring plate b breaks when the sliding metal is removed from the leaf spring due to a mechanical change and becomes unusable, or when the friction surface is sharpened and the rotation direction is reversed. There was also a problem such as.
[0008]
Further, since it is impossible to make the rotating surface and the fixing surface completely parallel to each other, the distance between the rotating surface and the fixing surface changes during the rotation. In such a case, the bending of the arched spring plate b is not in the vertical direction, so that there is a problem that the contact portion with the fixed surface of the spring plate b comes off from the fixed surface.
[0009]
The present invention is intended to solve the above-mentioned problems, and the object of the present invention is to make a rod-shaped brush made of carbon or the like slide in contact with the ring-shaped electrode plate, so that contact failure due to heat generation is prevented. It is an object of the present invention to provide a rotary power feeding device for a hair treatment promoting device that can be prevented and that there is no risk of breakage and that can prevent the brush from being reduced by reversing the direction of rotation.
[0010]
[Means for Solving the Problems]
The rotary power feeding device of the hair treatment promoting apparatus of the present invention is intended to achieve the above-mentioned purpose, and means for the heater includes a heater that irradiates infrared rays, a reflector that reflects infrared rays from the heater, and the reflector. A body case attached with a motor that rotates to irradiate the infrared rays along the top, rear, and both sides of the head of the patient, and a concentric ring electrode fixed to the body case side was formed. One substrate, a brush support plate that is fixed to the rotation shaft of the motor and rotates with the rotation of the motor, and a cylindrical portion is formed at opposite positions sandwiching the rotation shaft for each ring electrode, A spring accommodated in the cylindrical portion of the brush support plate and a carbon that is accommodated in the cylindrical portion and in which the arc-shaped portion at the tip is in sliding contact with the ring-shaped electrode is sintered by the spring force of the spring. And rod-shaped brush with more configurations, characterized in that so as to reverse the direction of rotation of the motor at a predetermined timing.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a rotary power feeding device of a hair treatment promoting device according to the present invention will be described with reference to FIGS.
FIG. 1 is a cross-sectional view showing the entire hair treatment promoting device. Reference numeral 1 denotes a lifting / lowering rod that can be raised and lowered according to the height of the head of a person to be treated, and a main body case 2 is attached to the upper end. Reference numeral 3 denotes a motor fixed in the vertical portion of the main body case 2, and a reduction gear (not shown) is built therein.
[0013]
Reference numeral 4 denotes a fixed plate fixed in the inclined portion of the main body case 2, and the motor 3 is supported on one end of the fixed plate 4, and the rotary shaft 5 is supported on the other end. A pulley 5 a is fixed to the rotary shaft 5, and a belt 6 is wound around the pulley 3 a fixed to the output shaft of the motor 3.
[0014]
Reference numeral 7 denotes a bracket fixed to a portion of the rotary shaft 5 protruding from the main body case 2, and a cover 7 a is integrally formed on the bracket 7. A ring-shaped reflector (not shown) is also provided inside the cover 7a, and an infrared ray containing a heating wire such as a nichrome wire in a ring-shaped tube made of ceramic, quartz glass, or the like is also provided inside the reflector. A radiant heater (not shown) is attached.
[0015]
As a method for rotating the bracket 7, a method in which the rotational force of the motor 3 is transmitted by the belt 6 is shown. However, as another method, the motor 3 and the bracket 7 are connected by a gear so that the motor 3 can be rotated. You may make it transmit a rotational force. Further, the reflector and the heater are not necessarily ring-shaped, but may be arc-shaped or arm-shaped.
[0016]
Reference numeral 8 denotes a power supply device for supplying power to the heater that rotates the power source introduced into the main body case 2, and details are shown in FIG. In FIG. 2, 81 is a substrate fixed in the main body case 2, and two concentric rings of ring-shaped fixed electrodes 81a are formed on the back surface side. A lead wire 82 from a power source introduced into the main body case 2 is connected to each fixed electrode 81a.
[0017]
83 is a brush support plate fixed together when the bracket 7 fixed to the rotating shaft 5 by the nut 5b is fixed, and a cylindrical portion 83a to which a metal brush holder 84 is fitted and fixed at four positions. Is formed. The brush holder 84 is connected to a lead wire 85 for energizing the heater.
[0018]
86 is a cylindrical or prismatic brush formed by sintering carbon or the like, is formed in a size that can be moved into the brush holder 84, and the tip 86a that contacts the fixed electrode 81a of the brush 86 is: When the brush 86 is manufactured, it is formed in an arc shape as shown in FIG.
[0019]
Two or more brushes 86 are opposed to one fixed electrode 81a. For example, one brush 86 can be grounded and another brush 86 can be used as a sub-heater (not shown). is there.
[0020]
The tip of the lead wire 85 is integrated with the brush 86 during sintering. A spring 87 for biasing the tip of the brush 86 toward the fixed electrode 81a is inserted into the brush holder 84.
[0021]
Next, the operation will be described based on the above-described configuration. When the motor 3 rotates and the rotating shaft 5 rotates, the brush support plate 83 is rotated together with the bracket 7 to which the heater is attached. As a result, the tip of the brush 86 rotates while being in sliding contact with the fixed electrode 81a, so that the current from the lead wire 82 flows to the lead wire 85 via the brush 86, and thus the heater is energized.
[0022]
If the rotation direction of the brush 86 is the direction of the arrow shown in FIG. 3A, the brush 86 is tilted to the left, and when this rotation direction is continued, the tip 86a of the brush 86 is in a half-reduced state.

Therefore, contact failure due to the one-side reduction of the brush 86 does not occur.
[0024]
In the embodiment described above, the case where the brush 86 side is rotated and the substrate 81 side on which the fixed electrode 81a is formed is fixed, but the substrate 81 side is rotated and the brush 86 side is fixed. It may be what you did.

【The invention's effect】
As described above, according to the present invention, in a power feeding device that energizes from a fixed power source to a heater that is rotated by a reflector, a plurality of spring-biased rod-shaped brushes and concentric rings that are individually slidably contacted with the brushes By configuring the power feeding device with the electrode, there is no change in the spring constant as in the conventional power feeding device using the spring plate, displacement from the ring electrode, or contact failure due to breakage of the spring plate.
[0026]
Further, by disposing two or more rod-shaped brushes opposite to the one ring-shaped electrode, even if one brush is separated from the ring-shaped electrode, sufficient contact can be performed and reliable power feeding can be performed. One brush can be used as a power source for other purposes, and the rotation direction of the motor is reversed at a predetermined timing to prevent the brush from being reduced. The power supply can be stably supplied by the stable contact, and there is an effect that no failure occurs.
