BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hair clipper with a hair absorption function that is optimal for pets such as dogs and cats.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a hair clipper with a hair absorption function for a pet that can cut the same hair while sucking hair and hair chips and trim the hair to a certain length has been known. As this type of hair clipper with a hair absorption function, for example, as shown in FIG. 11, a hair absorption case 2 is attached to the hair clipper main body 1, and the suction port 3 of the hair absorption case 2 is disposed close to the cutting blade 4 of the hair clipper main body 1. There was something to become. In this case, the suction port 3 is disposed close to the cutting blade 4 in the trimming direction front side, and guides the air flowing into the suction port 3 to the outer edge portion of the suction port 3 in the trimming direction front side and raises the guide cover. 5 is protrudingly extended.
[0003]
Therefore, in the hair clipper with a hair absorption function, the hair H to be cut is raised in advance by the suction action at the suction port 3 positioned on the cutting blade 4 in the trimming direction. At that time, air smoothly flows into the suction port 3 along the inner surface of the guide cover 5, and the hair H to be cut is surely raised by the force of the air flowing. The hair H in the raised state is cut by the cutting blade 4 and trimmed to a certain length. Here, by moving the tip edge of the guide cover 5 along the skin, the distance between the skin and the cutting blade 4 is kept constant, and the hair H has a constant length by the cutting blade 4. Disconnected. Moreover, the cut hair chips are sucked from the suction port 3 and sucked and removed into the hair absorption case 2 so as not to be scattered around.
[0004]
[Problems to be solved by the invention]
However, in the above conventional technique, in order to surely raise the hair H to be cut, the air passage area and the suction air volume at the suction port 3 are necessary, and in order to ensure these, the cutting blade 4 cannot enter and protrude into the suction port 3 too much. Therefore, the hair H raised along with the air flow along the inner surface of the guide cover 5 is biased away from the cutting blade 4 in the direction opposite to the cutting blade 4, and even though it has been raised, There was a problem that cutting efficiency was not good.
[0005]
The present invention was invented in order to solve the above-described problems in the prior art, and the problem was that a hair clipper with a hair absorption function with good cutting efficiency was obtained by raising the raised hair reliably with a cutting blade. Is to provide.

It was made to be characterized.
[0012]
Therefore, in this case, in particular, by performing the pruning operation with the attachment fitted, a gap is maintained between the skin and the cutting blade, and a predetermined length corresponding to the gap dimension is obtained. As described above, the hair can be safely cut leaving a long hair. Here, the peripheral wall portion of the attachment in the direction of trimming is the guide cover, and by moving the tip edge of the attachment along the skin, the distance between the skin and the cutting blade is kept constant, and the hair is the same. It is cut to a predetermined length by a cutting blade.
[0013]
Furthermore, a protruding line is projected on the inner surface along the edge of the suction port, and the protruding line is located behind the cutting blade, so that the raised hair is pushed and bent deeper than the cutting blade. In such a state, the cutting blade cuts more reliably. In addition, since the positions of the ridges and the cutting blades are shifted from each other, the air passage area and the suction air volume at the suction port are sufficiently secured, and the hair to be cut is raised more reliably. In addition, the trimming operation can be performed even with the attachment removed, and even at this time, there are ridges on the inner surface along the edge of the suction port, and the raised hair is securely cut by the cutting blade. The
[0014]
