Definitions

  • the present invention relates to electric hair clippers, and more particularly, to an improvement of an electric hair clippers in which a movable blade for cutting hair can move rightward and leftward and forward and backward so that hair cutting efficiency is enhanced.
  • Electric hair clippers are structured such that a movable blade, which is reciprocated in the lateral direction by a motor installed in a body and cuts hair, is closely installed on the upper side of a comb-shaped fixed blade so that when a power switch is manipulated, the movable blade eccentrically connected to a rotation shaft of the motor closely contacts the upper side of the fixed blade and reciprocates in the lateral direction to cut hair.
  • an adjusting ring is installed in the outer circumference of the body, a sliding member having a support protruded from the leading end thereof is provided in the body such that the support of the sliding member moves the movable blade forward and backward due to the manipulation of the adjusting ring to minutely adjust the cutting length of hair.
  • the conventional hair clippers are manually operated.
  • the movable blade is selectively moved forward and backward by the sliding member associated with the adjusting ring manipulated by a user, it is difficult to use the same.
  • the present invention has been made in view of the above and/or other problems, and it is an object of the present invention to provide an electric hair clipper capable of freely adjusting a cutting length of hair to be cut once so that cutting efficiency is enhanced, cutting time is reduced, and it is convenient to use.
  • an electric hair clipper including a fixed blade, a movable blade, and a moving device installed to the rear side of the movable blade to move the movable blade forward and backward such that the cutting length of hair is freely adjusted.
  • Figure 1 is a schematic view illustrating a conventional hair clipper
  • figure 2 is a plan view of an electric hair clipper according to a preferred embodiment of the present invention
  • figure 3 is a partially sectional view illustrating a major part of the electric hair clipper according to the preferred embodiment of the present invention
  • figure 4 is a perspective view illustrating a clutch holder of the electric hair clipper according to the preferred embodiment of the present invention
  • figures. 5a and 5b are reference views illustrating the assembly of the clutch holder and a clutch of the electric hair clipper according to the preferred embodiment of the present invention
  • figure 6 is a schematic perspective view illustrating an eccentric cam of the hair clipper according to the preferred embodiment of the present invention
  • figures. 7a to 7d are reference views illustrating the forward and backward movement of a movable blade generated by the eccentric cam of the hair clipper according to the preferred embodiment of the present invention.
  • the electric hair clipper includes a cylindrical body 10 in which a motor 30 and a rechargeable battery are installed, a manipulation switch and a pusher installed in the outer circumference of the body 10, a comb-shaped fixed blade 20 fixed to a front head of the body 10, and a movable blade 40 coupled with and closely contacting the upper side of the fixed blade 20 such that the movable blade 40 is reciprocated in the lateral direction by the motor 30 to cut hair.
  • the electric hair clipper includes a driving gear 60 of a reduction gear 50 for selectively transmitting driving force to a rotation shaft 31 of the motor 30 installed in the body 10 such that the movable blade 40 is moved forward and backward by the driving gear 60.
  • a clutch 62 having a plurality of cut-away portions radially cut away to penetrate a shaft assembly 61 is integrally installed.
  • the clutch 62 has an outer circumference surrounded by a bushing 63 made of a nonferrous metal and is accommodated in a clutch accommodating part 72 of a clutch holder 70.
  • the bushing 63 coupled with the outer circumference of the clutch 62 slides on the clutch 62 when the clutch 62 is rotated with the rotation shaft 31.
  • the clutch accommodating part 72 formed in a side of the clutch holder 70 has an opening formed by cutting away the lower side of the clutch accommodating part 72 such that the clutch accommodating part 72 is temporally contracted inward.
  • the shaft assembly 61 installed in the inner circumference of the clutch 62 has a saw tooth-shaped serration, and the rotation shaft 31 installed in the serration has also a saw tooth-shaped serration part 31a having a structure corresponding to the serration.
  • a wedge-shaped pusher accommodating part 74 is installed to allow a pusher 78 to enter and exit.
  • the pusher 78 is spread out when the pusher 78 is inserted into the pusher accommodating part 74 due to the vertical movement by a user so that the clutch accommodating part 72 purses inward to bite the clutch 62 and rotates together with the rotation shaft 31, and, conversely, when the pusher 78 exits from the pusher accommodating part 74, the clutch accommodating part 72 is spread out so that the external force applied to the clutch 62 is loosened, thereby preventing the clutch 62 from rotating together with the rotation shaft 31.
  • an auxiliary gear 54 installed to the reduction gear 50 is engaged with a gear 82 provided in an eccentric cam 80, an end of a pusher 90 assembled to the body 10 by a pin shaft 92 contacts the eccentric cam 80, and the other end of the pusher 90 contacts a fixed protrusion 42 installed the movable blade 40 to move the movable blade 40 forward using the pusher 90 moves relative to each other.
  • the eccentric cam 80 has a lozenge shape and corners 80a of the eccentric cam 80 are flat by a predetermined width such that the pusher 90 relatively moves due to the eccentric cam 80 to continuously push the fixed protrusion 42 of the movable blade for a predetermined period of time.
  • the body 10 includes an indicator 15 for indicating the movement of the movable blade 40 moved forward and backward by the pusher 90 associated with the eccentric cam 80 so that the forward movement of the movable blade is indicated.
  • the electric hair clipper operated as described above can adjust the cutting length of hair with a simple manipulation.
  • the clutch 62 includes the saw tooth-shaped serration formed in the shaft assembly 61 and the saw tooth-shaped serration part 31 a corresponding to the serration is formed in the outer circumference of the rotation shaft 31 assembled into the serration, when the external force is applied, the serration part 31 a is engaged with the serration so that the clutch 62 can rotate within the bushing 63.
  • the driving gear 60 for driving the reduction gear 50 also rotates.
  • the driving gear 60 sequentially transmits the driving force to the reduction gear 50, the auxiliary gear 54, and the gear 82 to rotate the eccentric cam 80, whereby the other end of the pusher 90 contacting the eccentric cam 80 exhibits seesaw movement about the pin shaft and repeatedly pushes the fixed protrusion 42 of the movable blade 40.
  • the driving gear 60 no longer rotates the reduction gear 50 so that the movable blade 40 does not move forward and backward, but stops, that is, is reciprocated in the lateral direction by the motor 30 to cut hair.
  • the electric hair clipper of the present invention since the movable blade reciprocates in the lateral direction and moves forward and backward, the cutting efficiency for hair is significantly enhanced. A user can easily cut hair so that cutting time is reduced and the uniform cutting length can be achieved. Moreover, the electric hair clipper of the present invention is easy to manipulate and convenient to use.
