Description

[Detailed description of the invention] The present invention relates to an electric hair clipper.

Conventionally, this type of electric hair clipper has a power switch button 25 on one side of the housing 1', as shown in FIG.
', and a movable blade operating button 25 was disposed on the front of the housing 1', making it inconvenient to operate because it had to be operated at two places.

The present invention eliminates the above-mentioned drawbacks, and is configured so that the power supply and the movement of the movable blade can be performed with a single operation button.
The purpose is to provide an easy-to-use electric hair clipper.

The electric hair clipper of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 1, reference numeral 1 denotes a housing, and one end portion of a driver 4 is mounted and fixed to mounting columns 2, 2 provided inside on both sides via screws 3, 3.

The side walls 5, 5 of the drive element 4 are provided with sufficient flexibility and are provided with a passive arm part 6 on the inner surface of the other end. , the drive arm portion 9 extending to the outer surface of the other end vibrates in a direction perpendicular to its extending direction.

For example, two pins 10 are fixedly installed at the tip of the drive arm portion 9, and are inserted into fitting holes 12 and 12 in the front portion of the movable blade 11.

The movable blade 11 is held in a slidable manner while being pressed against the fixed blade 13 by the force of a spring 14.14.
An engagement hole 17 for receiving a movable pin 16 at the tip of the movable arm 15 is provided at the rear, and the movable arm 15 is provided so as to be movable forward.

In this case, the teeth of the movable blade 11 are formed uniformly, while the teeth of the fixed blade 13 have a small tooth portion 1 that is approximately the same as the tooth pitch of the movable blade 11.
8 and a canine tooth portion 19 formed by cutting a large tooth groove into the small tooth portion 18.

Therefore, when the movable blade 11 retreats, the movable blade 11 moves back to the fixed blade 1.
Since it only engages with the canine tooth portion 19 of No. 3 and cuts only the hair that has entered the tooth groove that is relatively widely spaced, it is possible to perform a spacing (loose cutting) action on the hair, and when the movable blade 11 moves forward, the movable blade 11 meshes with the small teeth 18 of the fixed blade 13 to realize a cutting (close cutting) operation.

Further, the movable arm 15 itself has sufficient flexibility in the vibration direction of the driver 4, and has a driven pin 20 protruding from its base. It is provided so as to protrude outward from the housing 1 from an elongated hole 21 extending in a direction perpendicular to the vibration direction of the driver 4, that is, the sliding direction of the movable blade 11.

Furthermore, the movable arm 15 has screws 23.22 inserted into protrusions 22.22 provided inside the Ujifugu 1, sandwiching the elongated hole 21.
A presser plate 24 fixedly attached via a holder 23 prevents it from coming off.

Reference numeral 25 is an operation button, which is inserted into the drive element 4 through the elongated hole 21 on both side edges.
It is provided with an engaging membrane 27.27 that can be engaged in a guide groove 26.26 extending parallel to the vibration direction of the movable blade 11, that is, the sliding direction of the movable blade 11, and is slidably mounted on the outer surface of the housing 1.

A contact plate 28 is attached to the inner surface of the operation button 25, and a movable long groove 29 into which the driven pin 20 is engaged is formed.

The movable long groove 29 includes a horizontal portion 30 extending in the vibration direction of the drive element 4 and an inclined portion 31 extending diagonally toward the movable blade 11 with respect to the horizontal portion 30 .

Reference numeral 32.32 denotes a connection terminal suitably connected to the motor 8 and a power source (not shown), which is inserted through the hole 33.33, bent and fixed, so that its outer surface is connected to the contact plate 28 when the operation button 25 is slid. It is designed to be in contact with.

Further, the operation of the present invention will be explained in detail.

When the operation button 25 is not slid and is in the OFF position shown in FIG. 6, the contact plate 28 of the east operation button 25 does not come into contact with the connection terminals 32, 32, and the motor 8 etc. are not driven.

On the other hand, the operation button 25 is moved from the position shown in FIG. 7a to the position shown in FIG.
6 by a distance corresponding to the horizontal portion 30 of the movable long groove 29, the contact plate 28 and the connecting terminals 32, 32 are brought into contact and the motor 8 is driven.

At this time, the driven pin 20 is in the elongated hole 21 extending in the direction of extension of the guide grooves 26, 26, that is, in the direction perpendicular to the sliding direction of the operating button 25, and movement of the operating button 25 in the sliding direction is prevented. At the same time, since the horizontal portion 30 of the movable long groove 29 prevents the operation button 25 from moving in a direction perpendicular to the sliding direction, the movable blade 11 is positioned at a retracted position with respect to the fixed blade 13.

Therefore, the driving force from the motor 8 is applied to the eccentric cam 7 and the driver 4.
When the information is transmitted to the movable blade 11 via the movable blade 11, the movable blade 11 slides on the fixed blade 13, and a skiving operation is performed.

If the operation button 25 is further moved along the guide groove 26.26, the contact plate 28 and the connection terminal 32.32 will continue to be in contact with each other, as shown in FIG.
is moved within the elongated hole 21 of the housing 1 by the inclined portion 31 of the moving elongated groove 29 .

Accordingly, the movable blade 11 takes an advanced position on the fixed blade 13 via the °C moving arm 15, and a cutting operation is realized.

According to the electric hair clipper of the present invention configured as described above, it is possible to change the power supply and skid/cut operations with a single operation button, achieving remarkable effects such as extremely convenient usability. do.
