Description

[Detailed explanation of the invention] This invention relates to a so-called hair collection type electric shaver that collects cut hair waste in a specific chamber, and aims to further improve hair collection efficiency. .

This invention will be explained below according to the illustrated embodiments. 1 is a cylindrical main body case, 2 is a motor housed in this case, and 3 is a cylindrical main body case.
is the rotating shaft of this motor, and its tip protrudes outside the main body case 1.

Reference numeral 4 denotes a storage section formed at one end of the main body case 1 to surround this axis, 5 a mounting frame with both ends open that engages with the outer periphery of this storage section, and 6 dividing the inner cylinder of this mounting frame into upper and lower halves. A partition wall, 7 is an inlet bored in the partition wall and communicates the upper and lower parts of the inner cylinder of the mounting frame 5, and 8 is a mesh blade that covers the opening at the end of the mounting frame 5 to form a cutting chamber 9. an outer blade body having a surface 10;
Reference numeral 11 denotes an inner blade whose upper end blade surface is in pressure contact with the inner surface of the blade surface 10 of this outer blade body, and 12 is a stand on which this inner blade is mounted, and its lower end is fitted and connected to the motor shaft 3 and inserted into the cutting chamber 9. Decorated.

Furthermore, for this mounting, a plurality of protrusions 13 are provided on the outer periphery of the stand 12 and extend radially from the axis thereof, and the protrusions 13 and the inner cutter 11 are rotated integrally with the stand 12. At this time, the rotation locus drawn by the protruding rim 13 and the inner cutter 11 has a cylindrical shape approximately similar to the shape and size of the cutting chamber 9 shown in the figure.

Reference numeral 14 designates an annular concave casing 15 inside which the motor shaft 3 is passed through in a hollow space formed when the storage part 4 of the main body case 1 and the lower end opening of the mounting frame 5 are fitted together, and the rest of the casing 14 is placed outside. A casing 16 which is exposed and rotatably attached to the main body case 1 is a flat surface that rises from the bottom of the annular concave casing 15 of this casing and has a sufficient area to open the opening of the introduction lower. The introduction lower can be opened and closed by the flat surface of the convex portion provided with part A by rotating the housing 14.

17, when the introduction lower is opened with this convex part engaged with the main body case 1 and the mounting frame 5, this introduction port is opened and a long cylinder with a bottom is opened along the rotational direction of the inner cutter 11. an annular hair waste accumulation chamber that terminates at one side B of the convex portion 16;
Reference numeral 18 denotes a vent hole that is bored at the end of this accumulation chamber, that is, one side B of the convex portion 16, and opens this accumulation chamber to the outside;
The recessed housing portion 15 is connected so that this vent communicates with the outside.
A notch 21 is formed to communicate with the internal space 20 of the convex part 16 at the outer lower end of the convex part 16 so that the hair in the hair waste collection chamber 17 does not leak out from the notch. The hair collecting filter is detachably installed in the air vent 18 and covers the ventilation opening 18, for example, by pasting a thin cloth that is highly breathable but sufficient to trap hair debris.

Note that 22 is a switch that opens and closes in opposition to the opening and closing of communication between the accumulation chamber 17 and the cutting chamber 9, and is engaged with the housing 14.

In the above configuration, the switch 22 is closed by rotating the housing 14 from the outside, the introduction lower is opened, and the motor 2 is
When driven, the inner cutter 11 and the mounting base 12 rotate.

As a result, when the beard is cut, the beard that has entered from the blade surface 10 of the outer cutter 8 is cut off by the shearing action between the inner cutter 11 and the outer cutter 8, and this cut hair waste is scattered by the inner cutter 11 and the cutting chamber 9 However, since the rotational locus of the inner cutter 11 and the mounting table 12 forms a can-shaped path across the cutting chamber 9, the fluff is wiped away and falls off due to this can-shaped trajectory. The hair debris is removed by the centrifugal action of the mounting base 12 that rotates on the top surface of the partition wall 6. In other words, the hair debris that has fallen onto the base 12 is blown away in the outer circumferential direction by the rotation of the base 12, and the inner blade 11
The hair is moved from the introduction lower to the hair waste accumulation chamber 17 by the fan action of the protruding line 13.

That is, as shown in FIG. 1, due to the fan action of the inner cutter 11 and the mounting base 12, the outside air sucked from the blade surface 10 of the outer cutter 8 is used to vent the cutting chamber 9, the introduction lower, the lint accumulation chamber 17, and the convex portion 16. Mouth 18, space 20, hair collection filter 21 and cutout 19
As a result, as shown in the developed view of the hair waste collection chamber 17 shown in FIG. As shown in the figure, due to both the centrifugal and fan action exerted by the inner cutter 11 and the mounting base 12, the hair particles move within the hair collection chamber 17 and collide with the hair collection filter 21 at the end of this collection chamber. Only air passes through, and the hair debris is gradually accumulated from this point toward the introduction lower side. Therefore, the hair debris collides with each other one after another and accumulates, so that it is compressed into the hair debris accumulation chamber 17. Hair is collected.

When a sufficient amount of hair waste has been compressed and collected in the hair waste collection chamber 17, the entire length of the long-tubular hair waste collection chamber 17 can be opened by releasing the engagement between the frame 5 and the main body case 1. Therefore, compressed hair waste can be discharged all at once.

Further, at this time, the hair waste accumulation chamber 17, the convex portion 16, and the hair collection filter 21 can also be opened to the outside at the same time, so that they can be cleaned at the same time.

As described above, this invention provides a hair waste collection chamber directly below the cutting chamber that can be fully opened and closed by attaching and detaching it to the main body case so as to communicate with the cutting chamber through the inlet, and the hair waste collection chamber 17
A vent that communicates the hair waste collection chamber with the outside is formed in a convex part that bulges inward, and a hair collection filter is attached to this vent, and the rotating inner blade and its installation are The structure is such that the hair waste is transferred from the cutting chamber to the collection chamber and compressed and collected by centrifugal action with the table and fan action, so the hair collection efficiency is improved because the hair waste is compressed and collected by the ventilation. Not only is it excellent, but it is also easy to structure and manufacture because the inside of the convex part serves as a ventilation path with the outside.
Moreover, the outer side of the convex portion blocks hair debris, which has the effect of promoting airflow and compression and collection of hair debris.
