Description

The present invention relates to a suction type electric hair clipper.

2. Description of the Related Art In recent years, with the progress of an aging society, an increasing number of people spend most of their days lying on their backs in hospitals, nursing homes, homes, and the like. In the case of such a so-called "bedridden" person, it is often difficult to keep the body upright on the bed. For some people, even the slightest awakening of the condition can be difficult.

In general, when haircutting (so-called haircutting) of a person lying on the bed, a beautician or barber (hereinafter referred to as a "haircutter") treats the person to be haircut (hereinafter referred to as a "haircut person"). By supporting the head of the person to be styled, the hair of the person to be styled is often performed while securing a space between the bed and the head of the person to be styled. When the person to be styled is lying on the bed, the height of the back of the head of the person to be styled with respect to the upper surface of the bed is usually about 15 to 20 cm at most. It is not preferable to lift the head of the person whose hair is to be styled higher than this, considering that the burden on the person whose hair is to be styled increases.

Moreover, in hospitals or nursing homes, the person whose hair is to be styled may suffer from dementia or mental illness. In such a case, the hairdresser uses an electric suction clipper instead of the scissors for hairdressing used in beauty salons and barber shops in consideration of the safety of the hairdresser.

The electric suction clipper can be connected to a household electric vacuum cleaner by attaching an attached suction cover to the main body of the electric clipper. The person to be styled cuts the hair of the person to be styled with an electric hair clipper while sucking the hair with the electric vacuum cleaner, so that the cut hair is collected in the electric vacuum cleaner. The applicant has already invented a suction type electric hair clipper shown in Patent Document 1 and Patent Document 2.

Since both of the electric suction clippers of Patent Documents 1 and 2 have a built-in power source section, the electric clipper main body has a large shape correspondingly. If the structure is large, the handling (operability) of the electric suction clipper is not good, so there has been a demand for improvement.

Japanese Patent No. 6429302 Japanese Patent No. 6688515

An embodiment of an electric suction clipper will be described below with reference to the attached drawings. In addition, the same code|symbol was used for the same member in the figure. Also, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may differ from the actual ratios.

FIG. 1 is a side view showing the overall configuration of the electric suction clipper according to the embodiment. The electric suction clipper 100 is a handy device that is lightly gripped with one hand to trim (cut) the hair of a person to be trimmed. As shown in FIG. 1 , the hair clipper main body of the electric suction hair clipper 100 is composed of an upper case (first case) 110 , an intermediate case 120 and a lower case (second case) 130 . Top case 110, middle case 120, and bottom case 130 are plastic. The hair clipper main body is integrally formed by coupling the intermediate case 120 onto the lower case 130 and coupling the upper case 110 onto the intermediate case 120 .

A hair clipper blade 140 is detachably attached to one end of the lower case 130 . A space portion 150 is formed between the cutting edge portion 140 a of the hair clipper blade portion 140 and one end portion 110 a of the upper case 110 . The space 150 is a hair suction port.

When viewed from the side shown in FIG. 1, the suction width h between the edge portion 140a forming the space 150 and the end portion 110a is substantially equal to the length in the depth direction R of the edge portion 140a. The depth of the space portion 150 is longer than the cutting edge portion 140a of the hair clipper blade portion 140 and has the length of the end portion 110a of the upper case 110 in the lateral direction. 3 and 4, the width of the space 150 has the length in the longitudinal direction of the end portion 110a of the upper case 110 (the width of the cutting edge portion 140a).

As shown in FIGS. 3 and 4, the end portion 110a of the upper case 110 serves as a suction port for the cut hair through the space portion 150. As shown in FIG. When hair is trimmed, the hair of the person to be trimmed is sucked from the space 150 , and the sucked hair is cut by the cutting edge 140 a of the hair clipper blade 140 . The cut hair passes through a suction passage 160 (see FIG. 2) formed between the upper case 110 and the intermediate case 120 and is sucked into a suction hose 200 which will be described later. Therefore, according to the electric suction clipper 100, the clipped hair is not scattered around and is sucked by the vacuum cleaner (not shown) via the suction hose 200. FIG.

The cutting edge portion 140a of the hair clipper blade portion 140 includes a movable blade and a fixed blade (both not shown) that are formed vertically in a comb shape. The hair sucked into the end portion 110a of the upper case 110 via the space 150 is supported by the fixed blade. The movable blade horizontally reciprocates while in contact with the fixed blade. As a result, the hair is pinched and cut between the blade edges of the movable blade and the fixed blade.

FIG. 2 is a view of the electric suction hair clipper 100 viewed from the rear side, and a drawing showing a suction hose connected to the electric suction hair clipper 100, showing the shape of the electric suction hair clipper device. A suction passage 160 is formed between the upper case 110 and the intermediate case 120 to communicate with the space 150 in FIG. A connection opening 170 is formed at the end of the suction passage 160 . A pair of power terminals (power connection portions) 180 are provided inside the connection opening portion 170 of the suction passage 160 . In addition, an inclined member 190 is provided in front of the power terminal 180 inside the connection opening 170 (in the direction opposite to the suction direction). The inclined member 190 acts to attract the cut hair toward the upper wall side so that the cut hair does not get entangled with the power terminal 180 .

The right side of FIG. 2 shows the suction hose 200 connected to the connection opening 170 . One end of the suction hose 200 is connected to a vacuum cleaner (not shown), and the other end is provided with a hose cover 210 . In addition, the suction hose 200 is provided with a power connector 230 to which an external power line 220 is connected together with the hose cover 210 .

The hose cover 210 attached to the other end of the suction hose 200 is held by the first hose connection cover 550 and the opposing second hose connection cover 560 so as not to come off the suction hose 200 . Plunger mounting portions (not shown) are provided on both sides of the hose cover 210, into which the plungers 580 are press-fitted.

The hose cover 210 of the suction hose 200 and the power connector 230 are inserted into the connection opening 170 and are internally coupled by the plunger 580 . The power connector 230 is connected to the pair of power terminals 180 when inserted into the connection opening 170 . The electric suction clipper 100 of the embodiment does not incorporate a power supply unit. Therefore, the external power line 220 is connected to the substrate 440 (see FIG. 7), which will be described later, via the power connector 230 and the pair of power terminals 180 . As described above, the electric suction clipper 100 does not have a built-in power supply unit, so it has a compact shape.

Note that the configuration for supplying power may be changed in design as appropriate. For example, the power line 220 may be routed inside the suction hose 200 (eg, along wires in the hose) instead of being externally attached. Alternatively, a power connector (concave side) may be attached to the inside of the connection opening 170, and a pair of power terminals (convex side) may be attached to the suction hose 200 side.

A power switch 195 is provided on the back of the electric suction clipper 100 . The power switch 195 is operated by a user (for example, a hairdresser). The power switch 195 operates ON/OFF control of the motor 400 and ON/OFF control of the LED lighting unit 460, which will be described later. The user can perform an ON/OFF operation with a finger (for example, index finger) holding the hair clipper main body. The power switch 195 is, for example, a slide switch.
