Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cutting device and, more particularly, to a comb tooth portion having a pair of comb tooth plates facing each other at an interval, and between a comb tooth plate of the comb tooth portions. The present invention relates to a hair cutting device provided with a heater wire disposed and burned in contact with body hair combed between comb teeth.

[0002]

2. Description of the Related Art In general, this type of hair cutting device is used for treating waste hair before wearing a high-leg swimsuit or a leotard, for example. Japanese Patent Application Laid-Open No. 37521 or JP-A-8-289814 is known. Among them, the technique described in Japanese Utility Model Publication No. 4-37521 discloses a heater cassette in which a heater wire is stretched between conductive terminals protruding from both ends of a substantially bow-shaped base so as to be able to be inserted into and removed from the processing unit body. It is made. The technique described in Japanese Patent Application Laid-Open No. 8-289814 discloses a technique in which a comb tooth is detachably attached to a head, a head is detachably attached to a handle, and a heater wire is stretched between electrode members. And a pulling means for constantly applying a pulling force to the heater wire of the heater cartridge when the heater cartridge is mounted on the body hair treatment device main body or the head.

According to the hair cutting device configured as described above, the switch is turned on while the heater wire between the comb teeth plates is in contact with an appropriate length of the hair while combing the hair at the comb teeth. Then, the heater wire is energized and generates heat, so that the body hair portion in contact with the heater wire can be easily burned off. Also, unlike the case of cutting with a knife such as scissors or a razor, the tip of the burnt body hair does not become sharp, it becomes round, and the tip of the hair cracks as in the case of a knife. No defects.

[0004]

However, in the former, that is, the hair cutting device described in Japanese Utility Model Publication No. 4-37521, a heater cassette in which a heater wire is stretched between conductive terminals is connected to both comb teeth of the processing device main body. Since it is formed so as to be able to be inserted and removed between the plates, there is a problem that poor contact easily occurs between the conductive terminal and the power supply terminal on the power supply side. Further, it is necessary to provide guide strips which engage with each other on the comb tooth plate and the heater cassette in order to easily attach and detach the heater cassette.
For this reason, there has been a problem that the heater cassette becomes large and the comb teeth part becomes large, so that fine hair processing becomes difficult. Furthermore, since the heater wire is simply stretched between the conductive terminals, there is a problem that the heater wire, which has been heated by energization, expands and loosens, so that the hair cannot be cut smoothly. Further, in the latter, that is, in the hair cutting device described in JP-A-8-289814, the heater cartridge in which the heater wire is stretched between the electrode members is mounted on the body hair processing device main body or the head. Is provided with a pulling means for constantly applying a pulling force to the heater wire, so that the heater wire generated by energization does not become loose due to thermal expansion. However, the pulling means includes one of the electrode members on which the heater wire is stretched and the body hair treatment device main body. Alternatively, since it is formed by a coil spring wound around the head, there are problems in that the number of parts is increased, assembly is troublesome, and replacement when the heater wire is cut or damaged is troublesome.
