DETAILED DESCRIPTION OF THE INVENTION

First Embodiment First, a configuration principle of an example in which the present invention is applied to an electric razor will be briefly described with reference to FIG. The electric razor has a beard consisting of a net-shaped outer blade 2 having a large number of shaving holes installed in a semi-cylindrical shape on the head of a main body 1 and an inner blade body 3 having a large number of shaving blades sliding along its inner surface. It has a shaving portion. Further, in the substantially central portion of the main body 1, in this case, a drive device 4 for repeatedly swinging the inner blade body 3 in the axial direction of the semicylindrical outer blade 2 and a suction device 5 which is a blower for generating an air flow described later are provided. A drive unit including the drive unit is provided, and a power supply unit 6 including, for example, a dry battery, which supplies electric power to the devices 4 and 5 of the drive unit, is provided at the bottom of the main body 1. In addition to dry batteries, a rechargeable battery or a connection device with an AC power supply may be used for the power supply unit 6.

Further, inside the main body 1, a suction port 7 communicates with the internal space of the working portion which communicates with the outside air through a large number of shaving holes provided in the outer blade 2, and an outside air communicates with the discharge port 9 at the lower end of the main body. An air flow path 8 is provided. Therefore, if the suction device 5 is turned on simultaneously with or separately from the drive device 4 for the inner blade body 3, the shaving hole of the outer blade 2 passes through the suction port 7, the air flow path 8, and the discharge port 9 as shown by the arrow. The airflow emitted to the outside is generated by the blower, whereby the long beard hair near the shaving hole is sucked into the shaving hole together with the airflow sucked into the shaving hole, and is cut by the inner blade body 3.

In FIG. 1, a shaving blade having a substantially semicircular shape is used as the inner blade 3, but shaving blades having other shapes may be used.
In each case, there is sufficient space between adjacent shaving blades or shaving blade edges to draw in airflow and hair. Further, as for the shaving hole of the outer blade 2, since the shape thereof is already configured so as to be able to introduce long beard hair as described above, the shape of the outer blade shaving hole and the inner blade body of No special consideration is required for the configuration, but if a plurality of protrusions 2b are provided on the outer surface between the shaving holes 2a of the outer blade 2 as shown in FIGS. 2A and 2B, the skin 2c of the user can be Even when the outer blade 2 is pressed, a slight gap is generated around the protrusion 2b, so that smooth air suction is maintained. The same effect can be obtained by providing a ridge instead of the protrusion. If the suction device 5 is turned on and off separately from the inner blade drive device 4 as described above, the suction airflow is not used during normal shaving, and long shaving hairs and the like are shaved. Only the suction air flow can be used.

[0008]

Second Embodiment In a second embodiment of the present invention shown in FIGS. 3A and 3B, shaving of the beard hair by the outer blade and the inner blade body in the first embodiment, that is, the action of cutting the beard hair is replaced by a heating element. Utilizing the burning or burning action of the beard hair, it is possible to reliably treat not only ordinary short beard hair, but also long or long habitual, irregularly curved beard hair that has been inhaled by the inhalation airflow. It will be. In this case, since the cutting is not performed by the cutting blade, the shaving hole having the outer blade edge as the cutting blade may be a small hole for simply sucking in and introducing beard hair, and the inner shaving blade is not necessary.

Embodiment 1 in which the heating element is a movable cutting member
The movable inner member 13 corresponding to the inner blade body of the disk, in this case, a plurality of coil-shaped nichrome wires 13a between the pair of heat-resistant disks facing each other, are arranged in the circumferential direction of the disk. To the inner member 1 at equal intervals.
3 is formed in a substantially cylindrical shape as a whole. The disc is also preferably electrically insulating. On the other hand, Embodiment 1
The fixed outer member 12 corresponding to the outer blade is made of, for example, a thin plate of low thermal conductivity made of ceramic having a large number of small holes for simply introducing the hairs, and can be installed in the head of the main body 11 in a semi-cylindrical shape. . The cylindrical inner member 13 is arranged with its axis aligned along the inner surface of the semi-cylindrical outer member 12, and the drive device 14 rotates the cylindrical inner member 13 about its axis via the drive link 14a. If the power is supplied to the drive unit 14 from the power supply unit 16 and at the same time the power is supplied to the nichrome wire 13a of the inner member 13, the nichrome wire will be about 900 to 120.
The whiskers which generate heat at 0 ° C. and which are introduced from the small holes of the outer member 12 and come into contact with the circumferential surface of the nichrome wire or the entire space between the coils thereof are incinerated almost instantaneously by the heat. In this case, unlike the cutting by the cutting blade, the nichrome wire 13a does not necessarily need to have its peripheral surface in intimate contact with the inner surface of the outer member 12, and it is desirable that the nichrome wire 13a be rotatable with a slight gap. Although not shown for that purpose, a low ridge is provided on the inner surface of the outer member, or a disk added at both ends of the inner member or in the middle between both ends of the inner member slightly exceeds the peripheral surface of the nichrome wire. It can also be of diameter.

In the second embodiment, the air flow path 18 for sucking hair of the beard is slanted from the suction port 17 communicating with the inner space of the working portion inside the movable inner member 13 toward the side surface of the hair removing machine main body 11 as an example. Further, it extends along the side surface of the main body 11 and positions the discharge port 19 at the lower end of the main body 11 or in the vicinity thereof. The suction device 15, which is, for example, a blower, is provided in the oblique portion downstream of the suction port 17. The driving device 14 and the heating element 1
If power is supplied to the suction device 15 at substantially the same time as power is supplied to 3a, the outside air is sucked from the small holes of the outer member 12 to generate an air flow for introducing the beard hair as in the first embodiment, and the suction port 1
7 flows from the air passage 18 to the discharge port 19, while not only normal beard hair but also long beard hair is surely sucked into the small hole of the outer member and introduced, and as described above, the nichrome wire of the inner member. Incinerate at 13a.

Since the outer member 12 is made of a material having a low thermal conductivity, the high heat generated by the nichrome wire 13a is hardly transferred to the outer member, and the air flow generated by the suction device 15 first causes the outer air to flow to the outer member. The outer member 12 is always cooled by the outside air during the operation of the suction device because the outer member 12 is applied to the suction hole 12 and sucked through the rear small hole. Further, as described with reference to FIGS. 2A and 2B, when the outer member 12 has the protrusion or the protrusion 2b on the outer surface, the cooling effect by the outside air is enhanced. Therefore, it is possible to prevent the user's skin from being adversely affected by the heat generated by the heating element of the inner member during operation of the hair treatment device of this embodiment according to the present invention.

In the above-described second embodiment, the movable inner member 13 is described as being formed of a disk and a nichrome wire in a substantially cylindrical shape and rotated about the axis, but the structure of the inner member 13 is not limited to this. Not limited to this, for example, if the whole is formed in a substantially semi-cylindrical shape and oscillated around the axis, or if a number of short arc-shaped nichrome wires are arranged in a semi-cylindrical shape and reciprocally moved in the axial direction, the same result is obtained. The effect is obtained. In addition to the coiled nichrome wire, it goes without saying that if a plate-shaped or cylindrical electric heating element having a large number of holes can be manufactured by the fine ceramic technique, it can be effectively used as a movable inner member having a heat generating function. Yes.

[0013]

[Embodiment 3] In Embodiment 3 of the present invention shown in FIG. 4, the suction device 25 can be connected to the tip portion of the suction hose of an apparatus having an air flow suction function such as a vacuum cleaner other than the present hair treatment machine. It is formed of a rubber adapter, for example. In this case, the air flow path 28 extends from the suction port 27 inside the inner blade or the movable inner member 23 to the drive unit 24 and the power supply unit 26.
It is desirable that the discharge port 29 is provided so as to pass through the side portion of the main body 21 and to include the discharge port 29 that projects and opens on the bottom surface of the main body 21. This embodiment can be applied to both the case of using the shaving blade of the first embodiment and the case of using the movable inner member including the heating element of the second embodiment to achieve the same effect, and since the suction device can be omitted, the production cost can be reduced. Can be lowered.

[0014]

As described above, according to the present invention, the device for generating a beard sucking airflow, which is a remarkable feature of the present invention, is first incorporated into an electric razor for shaving with a conventional shaving blade. Long habit hair, downy hair, shin hair, axillary hair, etc. that are difficult to introduce inside from the shaving hole of the can be inhaled by the air stream inhaled from the shaving hole of the outer blade, and can be actively introduced. It becomes possible to disconnect. On the other hand, long hairs that have been positively sucked and introduced into the outer blade, especially habit hairs, cannot always be reliably captured and cut by the conventional inner blade. Therefore, by combining the beard hair suction airflow generation device according to the present invention with a movable inner member having a heat generating function, which is a further feature of the present invention, a long beard that is positively sucked and introduced by an intake airflow from the introduction hole of the fixed outer member. The hair can be reliably burned out by a heating element or completely burned.

The use of a beard sucking air stream also facilitates the cleaning of the beard waste, especially when combined with a shaving blade, and allows the beard waste that has been allowed to flow into the air flow passage without being stagnant at the shaving blade, for example at the outlet portion. It can be captured and collected. It is also possible to capture and collect the very small mustache produced when burning and burning with a heating element.
