Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hair cutting device, and more specifically, a comb tooth portion having a pair of comb tooth plates facing each other at intervals, and a comb tooth plate disposed between the comb tooth plates. The present invention relates to a hair cutting device comprising a heater wire that burns in contact with the hair that has been inserted in between.
[0002]
[Prior art]
In general, this type of hair cutting device is used, for example, for treating waste hair before wearing a high-leg swimsuit or leotard. As this type of hair cutting device, for example, Japanese Utility Model Publication No. 4-37521 or a special hair cutting device is used. Those described in Japanese Laid-Open Patent Application No. 8-289814 are known. Among them, (1) The technology described in Japanese Utility Model Publication No. 4-37521 is a method in which a heater cassette in which a heater wire is stretched between conductive terminals protruding from both ends of a substantially arcuate base is inserted into and removed from the processor body. It can be formed. (2) In the technique described in Japanese Patent Application Laid-Open No. 8-289814, the comb tooth portion is made detachable from the head, the head is made detachable from the handle portion, and the heater wire is interposed between the electrode members. In the state where the stretched heater cartridge is mounted on the main body of the hair treatment device or the head, it is provided with a pulling means that always applies a pulling force to the heater wire of the heater cartridge.
[0003]
According to the hair cutting apparatus configured as described above, when the heater wire between the comb teeth plates is brought into contact with the appropriate length portion of the hair while the hairs are combed at the comb teeth portion, When the heater wire is energized, it generates heat, and the hair portion in contact with the heater wire can be easily burned out. In addition, the ends of the burned body hair are not sharp unlike the case of cutting with a blade such as a razor or razor, and become rounded, resulting in cracks at the hair tip as in the case of the blade. There is no fault.
[0004]
[Problems to be solved by the invention]
However, (1) the former, that is, the hair cutting device described in Japanese Utility Model Publication No. 4-37521, makes it possible to insert and remove a heater cassette in which a heater wire is stretched between conductive terminals between both comb teeth plates of the processing device body. Since it is formed, there is a problem that contact failure between the conductive terminal and the power supply terminal on the power source side is likely to occur. Further, in order to facilitate the mounting and dismounting of the heater cassette, it is necessary to provide guide strips that engage with each other on the comb tooth plate and the heater cassette, so that the heater cassette becomes larger and the comb tooth portion becomes larger, and fine body hair treatment. There was a problem that it was difficult to do. Furthermore, since the heater wire is simply stretched between the conductive terminals, the heater wire that generates heat due to energization expands and loosens, and the hair cannot be cut smoothly. (2) In the latter, that is, the hair cutting device described in JP-A-8-289814, a heater cartridge in which a heater wire is stretched between electrode members is attached to the body of the hair processing device or the head. In the heater cartridge, the heater wire of the heater cartridge is always provided with a pulling means, so that the heater wire that generates heat due to energization does not loosen due to thermal expansion. Since it is formed by a coil spring that is stretched over the main body of the processor or the head, there are problems that the number of parts increases, the assembly becomes troublesome, and the replacement when the heater wire is cut or damaged is troublesome.
