Description

[0001]
[Industrial application fields]
The present invention relates to a hair cutting device that cuts beards, hair, and the like using wind power generated by suction force of a vacuum cleaner or the like, and an impeller used in the hair cutting device.
[0002]
[Prior art]
As a conventional example of the present invention, there is JP-A-4-244183, which will be described. The suction-type complex container shown in this publication is provided with a clipper at one end of a rotating shaft extending from both ends of a windmill and a shaving at the other end. Since two types of cutting instruments are provided, not only the structure becomes complicated, but also a clipper and a shaving blade are replaced as needed.
In order to clarify the comparison with the present application, only the comparison with the shaving side will be described. It is the same that a rotating blade for shaving is provided on the rotating shaft of the windmill and the windmill is rotated using wind power such as a vacuum cleaner. However, the blade of the windmill uses a T-shaped blade that protrudes from the peripheral wall surface of the cylindrical body. The wind power adjustment is arranged in a suction hose extending from the main body, and a special hose is necessary.
[0003]
[Problems to be solved by the invention]
A windmill using T-shaped blades loses efficiency without effective utilization of wind power, because the wind force partly flows through the gap between the cylindrical body and the T-shaped blade, and the shape of the entire windmill Had the disadvantage of becoming large.
This is because the rotational force is increased by providing the blade at a position away from the center of the rotating body. This is because if the rotational force is small, the rotary blade may be stopped by a resistance force applied to the whiskers, and the rotational force must be strengthened for smooth cutting. In addition, the provision of wind power adjustment means on the suction hose not only requires a dedicated hose, but because it is away from the instrument body to be held, it cannot be adjusted with the hand holding the instrument body. There were also drawbacks.
The present invention has been made to solve such problems, and an object of the present invention is to provide a hair cutting device having a strong rotational force and good operability and an impeller used in the device.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has the following configuration.
The hair cutting device according to claim 1 is provided with a cutting blade for hair cutting inside a front cover that covers the opening of the cylindrical main body and has a plurality of suction ports, and the cutting blade is an impeller also serving as a spring wheel. Connected to. By providing a shielding plate in front of the impeller to block the wind force sucked from the suction port, and by providing a ventilation path to apply wind from a part of the outer periphery of the shielding plate to a part of the impeller. A hair cutting device was obtained.
The hair cutting device according to claim 2 is provided with a cutting blade for hair cutting inside a front cover that covers the opening of the cylindrical main body and has a plurality of suction ports, and the cutting blade is an impeller also serving as a spring wheel. Connected to.
While providing a ventilation path which consists of the 1st ventilation path which applies wind power to a part of this impeller, and rotates an impeller, and the 2nd ventilation path which does not contribute to rotation of the said impeller, a 2nd ventilation path A hair cutting device was provided by providing a slide cover as a wind force adjusting means so as to block the wind.
The impeller described in claim 3 is provided with a plurality of blades made of a belt-like plate disposed obliquely with respect to the peripheral wall surface of the cylindrical body having a rotation axis. By forming at least one of the blades or the cylindrical body with a heavy object made of iron or lead, an impeller with an action of a flywheel was added.
[0005]
[Action]
When the action of the spring wheel is added to the impeller, the rotation force increases and the rotational force increases. Therefore, the rotary blade can cut smoothly without losing the resistance force of the hair. In addition, since the rotational force is strong, there is no need to install the blades away from the center of rotation of the cylindrical body, and a windshield strip can be directly attached to the cylindrical body, so use a small impeller. Can do.
When the ventilation path in the instrument main body is divided into the first ventilation path and the second ventilation path, the wind power can be adjusted in the main body, and the operability is good.

As shown in FIG. 3, a shielding plate provided with a seat plate-shaped ring 30 for guiding the sucked wind power to the air passage and a small hole 39 for supporting the rotating shaft of the impeller in the opening 22 of the device main body 21. 38.
Further, a convex portion 23 that forms a first ventilation path, which will be described later, is disposed on the top of the instrument body 21, and a knob 36 that adjusts the wind force of the second ventilation path, which will be described later, is disposed on the side wall. The air volume adjusting means 33 is formed by sliding the knob 36 in the direction of the arrow.
The ring 30, the shielding plate 38, the machine main body 21, and the like will be described in more detail.
[0009]
The ring 30 will be described with reference to FIG. The ring 30 has a seat plate shape with an opening at the center thereof, and a first cut 31 is provided on the outer side of the ring in accordance with the convex portion 23 shown in FIG. Further, in accordance with the arrangement position of the knob 36 shown in FIG. 3, a slide groove 34 made of a concave slit is formed on the outer peripheral wall surface of the ring, and a second notch 32 is connected to the slide groove.

Note that a notch (not shown) is also provided on the shielding plate 38 shown in FIG. 3 in accordance with the first cut 31 provided in the ring 30 and is used as a ventilation path.
The wind force passing through the first cut 31 is always circulated, and the wind force passing through the second cut 32 is to block or increase / decrease the wind force by moving the slide cover 35. These ventilation paths 50 will be described later together with the structure of the device main body 21.
[0010]
The cutting blade 48 shown in FIG. 2 and the impeller 40 that rotates the cutting blade will be described with reference to FIG. FIG. 5 is a perspective view showing the cutting blade and the impeller connected together. As shown in FIG. 5, the cutting blade 48 is a well-known one consisting of three blades used for general shaving and the like, and detailed description thereof is omitted. The cutting blade 48 is disposed inside the front cover 25 shown in FIG. 2, and cuts the hair inserted from the suction hole 26 by the rotation of the impeller.
[0011]
The impeller 40 is obtained by attaching a plurality of blades 44 made of an arc-shaped strip to the peripheral wall surface of a cylindrical body 42 having a rotating shaft 43 protruding as shown in FIG.
The blades 44 and the cylindrical body 42 have the effect of a spring wheel by using a heavy material, for example, a material such as iron or lead, so that the centrifugal force is increased by rotation. Further, the blade 44 is attached so as to descend like a slide along the peripheral wall surface of the cylindrical body 42 so that the blade 44 is not parallel to the rotation shaft 43 but is inclined, so that the wind force hitting the blade increases the rotational force. In this way, consideration is given to the effective use of wind power by flowing along the blades.
[0012]
In this way, by adding the action of a spring wheel to the impeller 40 and arranging the blades in a slanting manner, smooth cutting with a strong centrifugal force is possible without losing the resistance of the hair hitting the cutting blade 48. In addition, the impeller can be miniaturized. The cutting blade 48 is fixed to the tip of the rotating shaft 43 of the impeller 40 and is rotated by the small hole 39 of the shielding plate 38 shown in FIG. 3 and the bearing 28 of the rear cover 27 shown in FIG. It is held in a possible state.
[0013]
A ventilation path 50 for rotating the impeller 40 formed in this way by wind power will be described with reference to FIG. FIG. 6 is an explanatory view showing an arrangement relationship between the impeller and the machine body.
As described above, the impeller 40 attached to the shielding plate 38 and the rear cover 27 can be rotated and its speed adjusted by the flow of wind as shown in FIG.
That is, the wind force taken from the opening by the suction force of a cleaner or the like (not shown) comes into contact with the shielding plate 38 disposed in front of the impeller 44, and the first notch 31 and the second notch 31 of the ring 30 shown in FIG. From the notch 32, it flows into the instrument main body 21.
When the knob 36 shown in FIGS. 3 and 4 is moved in the direction indicated by the arrow in the drawing with respect to the second notch 32 provided in the ring 30 shown in FIG. 4, the slide cover 35 integrated with the knob 36 is used. The second cut 32 is blocked. As a result, the wind force flows only from the first cut 31 side of the ring 30 as indicated by an arrow A in the figure.
The wind force abuts against a part of the wing to rotate the impeller 40 strongly and flows from the opening indicated by the arrow B in the drawing to the cleaner outside the instrument body. The flow flowing from the arrow A to the wing in contact with the wing is the first ventilation path.
The wind flowing through the first ventilation path 52 does not impinge on the entire impeller 40, but is set so as to concentrate and contact only on one side around which the wings should be rotated with the rotation shaft 43 as the center.
Further, when the slide cover 35 is moved and the wind flows into the second notch 32 indicated by the arrow C in the drawing, this flow does not contribute to the rotation of the impeller 40 and is cleaned outside the instrument main body 21. It flows to the aircraft side.
The flow indicated by the arrow C is the second ventilation path 54, and the rotation of the impeller is adjusted by moving the slide cover 35 as the air volume adjusting means 33.
[0014]
As shown in FIG. 6, the machine body 21 to which the cutting blade 48 and the impeller 40 are attached is provided with a front cover 25 and a rear cover 27 as shown in FIG. 2 to provide the cutting tool 20 shown in FIG.
From such a state, when the machine main body is attached to the tip of a suction hose of a vacuum cleaner (not shown) and the vacuum cleaner is operated, the impeller 40 and the rotary blade 48 are rotated by the wind force generated by the suction force. And it can be used as shaving by applying the suction hole 26 portion of the front cover 25 to the beard.
Further, by attaching the length adjuster 12 shown in FIG. 1 to the front cover 25 and applying it to the head while setting the cutting length, the hair can be cut. In this shaving and hair cutting, the cut hair is sucked by a vacuum cleaner, so that the hair can be treated without soiling the surroundings.
[0015]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained by adding the action of the spring wheel to the impeller to increase the centrifugal force.
In other words, since the centrifugal force of the impeller is increased, it is not necessary to separate the blade attachment position from the rotating shaft. Therefore, since the blades can be directly attached to the columnar rotating body, the impeller can be reduced in size.
By adding the action of a flywheel, the rotational force became stronger and the thick beard could be cut smoothly.
Due to the downsizing of the impeller, the device body can also be set to a small size and can be easily held by hand, so that an effect such as a hair cutting device with good operability was obtained.
