| 20110010941 | NOSE HAIR TRIMMER WITH DUAL CUTTING EDGES - A nose hair trimmer with dual cutting edges which comprises a fixed blade with a plurality of teeth disposed on two opposite longitudinal sides thereof; a movable blade with a plurality of teeth disposed on two opposite longitudinal sides thereof, and the movable blade is driven by a driving unit to move in a linear reciprocating manner against the fixed blade so that the teeth on one side of the fixed blade and the teeth on one side of the movable blade cooperate with each other to define a first cutting edge, and the teeth on the other side of the fixed blade and the teeth on the other side of the movable blade cooperate with each other to define a second cutting edge; and a casing having a head portion in shape and size adapted to be inserted into a human nose, and the head portion is provided with two longitudinal openings disposed opposite to each other for exposing the first cutting edge and the second cutting edge respectively, so that the first cutting edge and the second cutting edge are positioned substantially parallel to a longitudinal axis of a nasal passage of a human nose when the head portion is inserted into the nose. | 01-20-2011 |
| 20090144988 | BLADE DRIVING ASSEMBLY FOR AN ADJUSTABLE HAIR CLIPPER - A blade driving assembly for an adjustable hair clipper of the present invention comprises a movable blade holder, a spring means, a spring holder and a push lever. The spring means is disposed with a coiled portion secured on the spring holder, a first portion which exerts pressure upon the movable blade holder to bias the movable blade towards the stationary blade and a second portion which biases the spring holder towards a retracted position. The spring holder is disposed with a connecting means at a front end thereof and a securing means at a rear end thereof for securing the coiled portion of the spring means, and the connecting means interlocks with the movable blade holder in such a way to allow the movable blade holder to move in a lateral reciprocating manner. The push lever is driven to move forward or backward by an external force, and a front end of the push lever abuts against the rear end of the spring holder in such a way to push the spring holder forward when the push lever is driven forward, and when the push lever is driven backward, the spring holder is biased by the spring means to retract until the rear end thereof abuts against the push lever. | 06-11-2009 |
| 20090119932 | Curved and toothed cutting blade for a trimmer and a grinding wheel for manufacturing therefor - A curved and toothed cutting blade for a trimmer comprising a base body having at least a connecting member for mounting onto a trimmer and a longitudinal cutting edge on one side which is symmetrically concave downward and has teeth, wherein the curve of the cutting edge is in the form of a segment of the interior of a circular arc of a lens with the two interior angles of any teeth not having different degrees of angle and the dent in between any two teeth being not perpendicular to the base pitch of the tips of the two teeth and slanted towards the center point of the curve of the cutting edge; and a grinding wheel for manufacturing the cutting blade, wherein the cutting blade is manufactured by a grinding wheel which is in the form of a lens with the two endpoints truncated with diameter being the largest in the middle and gradually decreasing towards the two ends and the surface of which has grooves of sizes and shapes which correspond to the sizes and shapes of the teeth of the cutting blade. The manufacturing process is simple and of low cost. | 05-14-2009 |
