Self-hair clipper
A self-hair clipper includes a housing ( 1 ), a motor ( 29 ) in the housing ( 1 ) for driving a blade ( 18 ); and a comb adjusting mechanism that forms a space for receiving the motor ( 29 ) therein, the comb adjusting mechanism includes two cam wheels ( 3 ), and wherein the motor ( 29 ) is positioned between the two cam wheels ( 3 ).
1. A self-hair clipper including:
a motor for driving a blade; and
an adjusting mechanism for an associated comb, wherein the adjusting mechanism defines a space for receiving the motor therein, and wherein the adjusting mechanism comprises:
two cam wheels, wherein the motor is positioned between the two cam wheels, and wherein each cam wheel includes a cam and a gear integrally formed;
a comb control that includes a rack, the rack having teeth; and
a slider that includes two separated holders for supporting the two cam wheels;
wherein the gears of the two cam wheels engage the teeth of the rack of the comb control, and the space for receiving the motor is formed between the two holders.
2. The self-hair clipper according to claim 1 , wherein the motor is obliquely positioned between the two cam wheels.
3. The self-hair clipper according to claim 1 , further including:
a comb for controlling hair length during cutting;
the slider includes two separated attaching legs extending downwardly for fixing the slider to the comb.
4. The self-hair clipper according to claim 3 , wherein the two cam wheels rotate synchronously in the same direction when the comb control is actuated.
5. The self-hair clipper according to claim 1 , wherein the two cam wheels rotate synchronously in the same direction when the comb control is actuated.
6. The self-hair clipper according to claim 1 , wherein the rack has a gear modulus (m) of 0.5, a pitch circle diameter of 184 mm, a number of teeth of 368 and a gear pitch (t) of 1.57 mm,
the gear of the cam wheel has a gear modulus (m) of 0.5, a pitch circle diameter of 15 mm, a number of teeth of 30 and a gear pitch (t) of 1.57 mm.
7. The self-hair clipper according to claim 1 , wherein
the blade projects towards a projection side of the self-hair clipper for cutting hair; and
the self-hair clipper further includes a housing that defines a space to receive components of the self-hair clipper therein,
characterized in that the housing includes two surfaces adjacent to the blade, the two surfaces are tilted towards a side of the self-hair clipper opposite to the projection side at an obtuse angle.
8. The self-hair clipper according to claim 7 , wherein the obtuse angle is 153 degrees.
