Description

  The present invention relates to a suction type electric hair clipper that can cut its own hair on a desired trimming surface with one hand and sucks hair that has been cut with an electric hair clipper blade portion into a suction machine without scattering it around.

As this type of clipper, the electric clipper is detachably attached to a cylindrical case with one end opening behind the blade of the electric clipper and the other end connected to a suction machine. There has been proposed one in which a plate-like lever that interlocks with this switch is provided so as to be tiltable (see, for example, Patent Document 1). In the case of the suction type electric hair clipper described in Patent Document 1, since the electric hair clipper blade portion disposed outside the suction port directly contacts the hair and cuts the hair, the hair cut length and the like are made uniform. It is difficult for the user to use, and the cut hair that has been sent from the suction port to the suction machine in the cylindrical case is entangled in the plate lever restoring mechanism and is likely to break down. It was.
In addition, a plurality of suction covers are selectively and detachably attached to one end opening of the suction cylinder portion so as to cover the electric clipper blade body, and a suction port is formed in each suction cover, and each suction cover is used for cutting height adjustment. Suction-type electric motors that have comb teeth that are integrally formed with different cutting heights, and the opening area of the suction cover with a low cutting height is narrower than the opening area of the suction cover with a high cutting height A clipper has been proposed (see, for example, Patent Document 2). In the invention described in Patent Document 2, there is a problem that the length of the hair is cut to a length corresponding to the length of the bottom surface of the comb teeth and the length of the comb teeth, and the length of the hair cannot be freely set.
Further, there has been proposed a suction type electric hair clipper in which a hair collection constriction portion is provided in a suction tube connected to a suction device, and the electric hair clipper is attached to the suction tube with the electric hair clipper blade portion facing the hair collection narrowing portion ( For example, see Patent Document 3). In the invention described in Patent Document 3, since the narrowed portion has already been formed in the suction cylinder, the cut hair cannot be fed into the suction cylinder unless it is a small amount of hair. There is a problem that the cut hair is clogged in the narrowed portion and causes failure.
Also, a suction air passage is provided on the outer surface of the electric hair clipper equipped with the hair clipper blade driving device and the hair accumulation container, the suction port end of the suction air passage is formed in the comb teeth, and the clipper blade is disposed in the suction mouth perpendicular to the comb teeth. An arranged portable electric hair clipper has been proposed (see, for example, Patent Document 4). With the invention described in Patent Document 4, hair can be cut only by the length from the outer end of the comb teeth to the tip of the clipper blade. In addition, since it is portable, the drive source must rely on electric power such as a dry cell, so that there is a problem that it is not suitable for full-scale cutting and is not suitable for actual use.
Moreover, although the thing of patent document 5 or 6 is proposed as a comb tooth with which a clipper is mounted | worn, since it is the structure which cannot change the outer edge edge inclination angle of a comb tooth, various cutting-up angles have it. It is not suitable as a required adult male hair clipper.
Moreover, since the comb tooth of patent document 7 or 8 does not form the inclination in the hair insertion side, there existed a problem that it cannot be used for the hairstyle which requires the steep slope of the adult male.
