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 2 on one side of the housing 1', as shown in FIG.
5' is attached, and a movable blade operation button 25 is disposed on the front of the housing 1', and the operation must be performed at two places, making it inconvenient to use.

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 explained below along with the drawings.

In FIGS. 1 to 6, 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 a passive arm part 6 is installed inside the other end thereof, so that when receiving the driving force of the motor 8 via the eccentric cam 7, , the drive arm part 9 protruding from the outer surface of the other end vibrates in a direction perpendicular to its extension direction.

For example, two pins 10 are fixed to the tip of the drive arm portion 9, and are engaged in fitting holes 12.degree. 12 in the front portion of the movable blade 11.

The movable blade 11 is held so as to be slidable while being pressed against the fixed blade 13 by the spring force of a spring 14.14,
An engagement hole 17 for receiving the movable bottle 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 large tooth portion 19 of No. 3 and cuts only the hair that is in the tooth groove that is relatively widely spaced, it is possible to perform a sparse (sparse cutting) action on the hair, and it is movable when the movable blade 11 moves forward. The 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 a driven pin 20 is provided protruding from the base. It is provided so as to protrude outward from the elongated hole 21 extending perpendicularly to the vibration direction of the driver 4, that is, the sliding direction of the movable blade 11.

Further, the movable arm 15 is prevented from slipping off by a retaining plate 24 which is fixed to a protrusion 22.22 provided inside the elongated hole 21 via screws 23.23.

Reference numeral 25 denotes an operation plate which is provided on both side edges with the elongated hole 21 in between.
Guide grooves 26, 26 extending in parallel in the same direction as the extending direction of
It is provided with an engaging membrane 27.27 that can be engaged with the housing 1 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 plate 25, and an L-shaped protrusion 29 that extends upward and has a vertical portion 30 from which the driven pin 20 can be projected when the operation plate 25 slides is provided. One end of a leaf spring 31 is fixed to the outer edge of the vertical portion 30.

The leaf spring 31 is detoured in an L-shape along the inner edge of the protrusion 29 and curved upward in a U-shape, and the body portion 31a on the free end side is connected to the body portion 3 on the side along the inner edge of the protrusion 30.
1b and is given a spring force so as to come into contact with the body 31b, and the free end is curved in an arch shape so as to be engaged with the driven pin 20 protruding from the housing 1. The driven pin 20 is formed to prevent movement of the driven pin 20.

Reference numeral 32 designates an intermediate pin protruding from the outer surface of the housing 1, which is connected to the body portion 31a of the leaf spring 31 when the operation plate 25 is not slid.

31b.

33. Reference numeral 33 denotes a connection terminal suitably connected to the motor 8 and a power source (not shown), which is inserted through the hole 34, 34, bent and fixed. 28.

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 as shown in FIG.
33, and the motor 8 etc. are not driven.

On the other hand, the operation panel 25 is moved from the position shown in FIG. 6A to the position shown in FIG. 6S.

That is, when the operation plate 25 is slid along the guide groove 26.degree. 26, the contact plate 28 and the connection terminals 33,33 are brought into contact and the motor 8 is driven.

At this time, the intermediate pin 32 is detached from the body parts 31a, 31b of the leaf spring 31, and the body parts 31a, 31b are bent so as to come into contact, and a large spring force is applied to the free end of the leaf spring 31, so that the driven pin 20 can be moved within the elongated hole 21, and the movable blade 11 assumes a retracted position relative to the fixed blade 13.

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

If the operation plate 25 is further moved along the guide grooves 26, 26, the contact plate 28 and the connection terminal 33 will be connected to each other as shown in FIG. 6C.
．． 33, the driven pin 20 is pushed forward by the tip of the vertical portion 30 of the protrusion 29, and the driven pin 20 is pushed forward by the tip of the vertical portion 30 of the protrusion 29, and
It moves in the elongated hole 21 of.

Therefore, the movable blade 11 takes an advanced position on the fixed blade 13 via the movable 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.
