Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an electric hair clipper, and its main purpose is to reduce power consumption.

[Prior art]

Conventionally, electric clippers can be used for plowing and border cutting in addition to round cutting.

However, even though the number of hairs cut during plowing and edge cutting is extremely small compared to round cutting, the motor is driven with the same power as for round cutting, so there is a corresponding waste of electricity. Ta. In addition, when finishing mowing such as edge mowing or plowing, it is preferable to reduce the vibration of the main body and perform the work with as little camera shake as possible.

[Purpose of the invention]

Focusing on this fact, this invention reduces the power of the motor when mowing other than round mowing, reducing power consumption and vibration, and also prevents erroneous operation of switching the motor power. It is intended to provide hair clippers.

〔Example〕

The details will be explained below based on the drawings.

1 to 6 illustrate an electric hair clipper according to the present invention, in which a hair clipper-type reaping device 2, a vibrator 3 for driving the same, a motor 4, and a battery 5 are installed in the main body case 1 in order from the front. The main body case 1 is also removably equipped with two types of cutting method adjustment attachments 6, one for high power and one for low power.

The reaping device 2 has a fixed blade 9 fixed to a fixed blade support 8 which is removably pivoted to the main body case 1 via a support shaft 7, and a movable blade 11 fixed to a movable blade support 10. A helical spring 13 attached to the movable blade support 10 via a support shaft 12 presses and biases the upper surface of the fixed blade 9 so that it can freely slide into contact with the upper surface of the movable blade support 10. The movable blade 11 is caused to vibrate in the left-right direction via the vibrator 3 by engaging the arm 15 at the tip of the movable blade 11 with the rotation of the motor 4.

A switch operation knob 16 is attached to the bottom wall of the main body case 1 so as to be slidable in the front and rear directions with the off position at the center. Switch 17.

The switch 17 connects its movable electrode 37 to the positive pole of the battery 5, connects the first contact 20 of the switch 17 directly to the motor 4, opens the second contact 18, and connects the third contact 21 to the positive terminal of the battery 5 through the diode 22. Connected to motor 4. Therefore, when the operation knob 16 of the switch 17 moves from the off position A at the center in the longitudinal direction to the on position B at the rear, the switch 17 enters the first contact 20 side, so the motor 4 is directly connected to the battery 5, and normally It rotates at high power with a rotation speed of . When moving from OFF position A to ON position C, switch 1
7 enters the third contact 21 side, and the battery 5 is connected to both ends of the motor 4 via a diode 22. At this time, a voltage lower than the output voltage of the battery 5 by the voltage drop caused by the diode 22 is applied to the motor 4, and the motor 4 rotates at a rotation speed slower than usual.

As the high-power cutting method adjustment attachment 6, a hair cutting height adjustment tool 24 is illustrated in the drawing, and this cutting height and height adjustment tool 24 has a comb board 25 that can be inserted and removed from the front end of the main body case 1. The comb board 25 has comb teeth 26 arranged in a row at the front end of the comb board 25. When the comb board 25 is inserted into the front end of the main body case 1, the comb teeth 26 face the fixed blade 9 at a constant interval, and the comb board 25 faces the fixed blade 9 at a constant interval. When the comb board 25 is attached, the operation knob 16 of the switch 17 is set to the low power switching position C.
The operating knob movement regulating portion 27 is formed in a recessed manner so as to be concealed and prevented from moving to the high power switching position.

On the other hand, as the low power mowing adjustment attachment 6, a plow cutting comb 28 is illustrated in the drawing, and this plow cutting comb 2B includes a comb board 29 that can be inserted into and removed from the front end of the main body case 1, and the comb board 29. When the comb board 29 is inserted into the front end of the main body case 1, the grooves 30 wrap with the cutting edge of the fixed blade 9, and the comb teeth 31 are arranged with grooves 30 in a row. A chisel is provided for mowing the plow, and when this is attached to the rear end of the comb board 29, movement of the operation knob 16 of the switch 17 to the high power switching position B is concealed and regulated, and a low power switching position C is also provided. This opens the operating knob movement restricting portion 27, which can be switched and moved only in this manner.

In such a case, when the cutting method adjustment tool 24, which is the high-power cutting method adjustment attachment 6, is attached as shown in FIGS. Movement to the switching position C is restricted and movement is possible only to the high power switching position B. At this time, when the operation knob 16 is moved to the high power switching position B, the motor 4 operates at a high power suitable for the load of circular cutting. The movable blade 11 is driven by rotating at a normal rotation speed. Remove the cutting height adjuster 24 and set it as shown in Figure 5 (1).
) (II) When the plow cutting comb 28, which is the low-power mowing adjustment attachment 6, is attached, the operation knob movement restriction section 27 allows the operation knob 16 to move only to the low-power switching position C. At this time, when the operating knob 16 is moved to the low power switching position C, the battery 5
is connected to the motor 4 via a diode 22 to form a low power circuit. Therefore, diode 2 is connected to motor 4.
A voltage that is lower than the output voltage of the battery 5 by the voltage drop caused by 2 is applied, and the motor 4 rotates at a rotation speed A at a steady state, for example, to drive the movable blade 11, which is slower than the normal rotation speed.

Note that the operating mode of the operating knob 16 of the switch 17 may be, for example, a rotating type in addition to the sliding type. In this case, the operation knob movement regulating section 27 of the cutting method adjustment attachment 6
The direction of switching to high power or low power is regulated.

Further, instead of setting the off position at the center of the operating knob 16 of the switch 17, the switch 17 may be switched to the low power side when advanced one step.

In this case, when using the attachment 6 for low power, the position of the operation knob 16 cannot be regulated, but after switching to the high power side and reaching a steady rotation speed, it will switch to the low power side. Even if the input power to the motor 4 at the time of switching is small, there is no risk of starting errors due to insufficient starting torque.

In addition to the above-mentioned plow comb, the low-power cutting method adjustment attachment 6 may be, for example, a edge cutting tool.

In the above embodiment, the rotational speed of the motor 4 can be switched in two stages, but as shown in FIG. 7, it may be switchable in three or more stages.

In this case, the number of diodes 22 and 38 inserted in series in the current-carrying circuit will be increased sequentially in accordance with the voltage to be lowered.

Furthermore, the switch 17 can be arranged separately for power switching and for power on/off.

In this case, the mowing method adjustment attachment 6 regulates the movement of the operating knob of the power changeover switch.

[Effect]

As described above, the electric hair clipper of the present invention is equipped with a switch 17 that can switch the power of the motor 4 between several high and low levels, and the power input to the motor 4 is controlled by the use of the detachable cutting style adjustment attachment 6. Since the size can be changed to match the weight or weight of the load applied to the motor 4, the usable life of the battery can be extended, especially in the case of a battery type. Moreover, by providing the operating knob movement regulating section 27 on the cutting method adjustment attachment 6 and attaching it, the operating knob movement regulating section 27 enables switching operation of the operating knob 16 only to a position corresponding to the load of the attachment 6. This eliminates operational mistakes such as switching to low power when installing the high power cutting adjustment attachment 6, or conversely switching to high power when installing the low power cutting adjustment attachment 6. Enable correct usage. In addition, by lowering the rotation speed of the motor 4 during plowing and edge cutting, the vibration transmitted to the main body is reduced, preventing camera shake, preventing cutting mistakes, alleviating the fear of over-cutting, and reducing the rotation speed. By reducing the sound volume of hair clipping due to the change in the sound, there are advantages such as less harshness and more comfortable usage.

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an electric hair clipper, and its main purpose is to improve the efficiency of haircutting using the hair clipper. [Prior Art] Conventionally, in addition to round cutting, electric hair clippers have been used to perform combing, edge cutting, etc. depending on the hair style, hair location, etc. However, in the case of plowing, edge cutting, or haircuts for infants and young children, the motor is driven to rotate with the same power as for round cutting, even though the number of hairs to be cut is extremely small compared to round cutting. There was a lot of wasted power consumption. Also, when finishing cutting such as edge cutting and plowing,
It is preferable to reduce the vibration of the main body and perform the work with as little camera shake as possible. Furthermore, it is preferable that the driving noise be as low as possible, and it should not cause fear especially in young children. [Object of the Invention] Focusing on this fact, the present invention aims to reduce power consumption and vibration by appropriately varying the rotation speed of the motor depending on the situation during haircutting, and also provides an operation for switching the rotation speed of the motor. The purpose of the present invention is to provide an electric hair clipper that is easy to handle and has excellent handling properties. [Example] The details will be explained below based on the drawings. 1 to 3 and 6 illustrate an electric hair clipper according to the present invention, in which a hair clipper-type reaping device 2, a vibrator 3 for driving the hair clipper, and a vibrator 3 for driving the electric hair clipper are shown in the main body case 1.
, a motor 4, and a battery 5 as a power source. The reaping device 2 has a fixed blade 9 fixed to a fixed blade support 8 which is removably pivoted to the main body case 1 via a support shaft 7, and a movable blade 11 fixed to a movable blade support 10. A helical spring 13 attached to the movable blade support 10 via a support shaft 12 presses and biases the upper surface of the fixed blade 9 so that it can freely slide into contact with the upper surface of the movable blade support 10. The movable blade 11 is caused to vibrate in the left-right direction via the vibrator 3 by engaging the arm 15 at the tip of the movable blade 11 with the rotation of the motor 4. A switch operation knob 16 is attached to the bottom wall of the main body case 1 so as to be slidable in the front and rear directions with the off position at the center. Switch 17. The switch 17 connects its movable electrode 37 to the positive pole of the battery 5, connects the first contact 20 of the switch 17 directly to the motor 4, opens the second contact 18, and connects the third contact 21 to the positive terminal of the battery 5 through the diode 22. Connected to motor 4. Therefore, when the operation knob 16 of the switch 17 is moved from the OFF position A at the center in the longitudinal direction to the rear ON position, the switch 17 enters the first contact 20 side, so the motor 4 is directly connected to the battery 5, and normally It rotates at high power with a rotation speed of . When moving from the off position A to the on position C, the switch 17 enters the third contact 21 side, and the battery 5 is connected to the diode 2.
2 to both ends of the motor 4. At this time, a voltage lower than the output voltage of the battery 5 by the voltage drop caused by the diode 22 is applied to the motor 4, and the motor 4 rotates at a rotation speed slower than usual. That is, the motor 4 can be switched between high-speed drive, low-speed drive, and stop using a single operation knob 16, and high-speed drive and low-speed drive can be selected with a single touch from the motor stopped state. The optimum motor drive can be selected as appropriate. [Other Embodiments] In addition, by linking such a single operation knob 16 with a cutting style adjustment attachment, it is possible to set the driving speed suitable for the cutting style without mistakes. As such means, for example, as the high-power cutting method adjustment attachment 6, a hair cutting height adjustment tool 24 is illustrated in the drawing, and this cutting height adjustment tool 24 is attached to the front end of the main body case 1. The seed board 25 has a seed board 25 that can be inserted and removed from the main body case 1, and comb teeth 26 are arranged in a row at the front end of the seed board 25. When the seed board 25 is inserted into the front end of the main body case 1, the comb teeth 26 are spaced apart from the fixed blade 9 by a certain distance. The rear end of the seed board 25 is provided so that the operation knob 16 of the switch 17 moves to the low power switching position C when the seed board 25 is installed. An operating knob movement regulating portion 27 is formed in a recessed manner so as to be concealed and restricted and to be able to switch and move only to the high power switching position B. On the other hand, as the low power mowing adjustment attachment 6, a plow cutting comb 28 is illustrated in the drawing, and the plow cutting comb 28 includes a seed board 29 that can be inserted into and removed from the front end of the main body case 1, and the seed board 29. When the seed substrate 29 is inserted into the front end of the main body case 1, the grooves 30 overlap with the cutting edge of the fixed blade 9, and the comb teeth 31 are arranged with grooves 30 arranged in a row. A chisel is provided for mowing, and when this is installed on the rear end of the seed board 29, movement of the operation knob 16 of the switch 17 to the high power switching position B is concealed and regulated, and a low power switching position C is also provided. This opens the operating knob movement restricting portion 27, which can be switched and moved only in this manner. In such a case, when the cutting height adjuster 24, which is the high-power cutting method adjustment attachment 6, is attached as shown in FIG. Movement to the switching position C is regulated and movement is possible only to the high power switching position 1FB.At this time, when the operation knob 16 is moved to the high power switching position B, the motor 4 operates at a high power suitable for the load of circular cutting. The movable blade 11 is driven by rotating at a normal rotation speed. After removing the cutting height adjuster 24, as shown in FIG. 5(1)(n), the low power cutting method adjustment attachment 6
When the plow cutting comb 28 is attached, the operating knob 16 is moved to the high power switching position B by the operating knob movement regulating section 27.
When the operating knob 16 is moved to the low power switching position C at this time, the battery 5 is connected to the motor 4 via the diode 22. to form a low power circuit. Therefore, a voltage lower than the output voltage of the battery 5 by the voltage drop caused by the diode 22 is applied to the motor 4.
The motor 4 has a rotation speed slower than normal, e.g. % at steady state.
It rotates at a rotational speed to drive the movable blade 11. Furthermore, the operation knob 16 of the switch 17 may be switched to the low power side when advanced one step, instead of having the off position located at the center. In this case, after switching to the high power side and reaching a steady rotation speed, it switches to the low power side, so even if the input power to the motor 4 is small when switching to the low power side, the starting torque will not be insufficient. There is no risk of a startup error. In each of the embodiments described above, the rotational speed of the motor 4 can be switched in two stages, but as shown in FIG. 7, it may be switchable in three or more stages. In this case, the number of diodes 22 and 38 inserted in series in the current-carrying circuit will be increased sequentially in accordance with the voltage to be lowered. Further, the power source section 5 may of course be an electric hair clipper using an AC power source other than the battery as shown in the above embodiment. [Operation and Effect] As explained above, according to the electric hair clipper of the present invention, by reducing the rotation speed of the motor 4 during plowing, edge cutting, etc., vibrations transmitted to the main body are reduced, and camera shake is prevented. It has the advantage of preventing cutting errors, alleviating the fear of over-cutting, and reducing the volume of hair trimming due to changes in the rotational speed, resulting in less harshness and more comfortable use. In addition, the operation knobs for the power switch and rotation speed switch are not separate,
Since it is controlled by a single operation knob 16, it has excellent operability, and can be switched between high speed drive, low speed drive, and stop with one touch, making it easy to handle during haircutting work. 4.
