LASH BRUSH
A lash brush includes a case, a rotatable shaft, a plurality of bristles and a reciprocating transmission mechanism, the rotatable shaft is driven into reciprocal motion along an axial line by the reciprocating transmission mechanism, a first unit of the reciprocating transmission mechanism comprises an actuating surface having a plurality of spacing members, a second unit of the reciprocating transmission mechanism comprises a contacting terminal contacting against each of the spacing terminals in sequence to make the rotatable shaft vibrate back and forth instantaneously along the axial line.
The present invention is generally related to a lash brush, which particularly relates to the lash brush for making a rotatable shaft instantaneously vibrate back and forth along an axial line.
BACKGROUND OF THE INVENTIONA conventional lash brush 10 as illustrated in
The primary object of the present invention is to provide a lash brush for making a rotatable shaft coupled to a plurality of bristles vibrate back and forth instantaneously along an axial line. When the mascara applies onto the eyelashes, the lash brush prevents the mascara attached onto the eyelashes from forming as patch-shaped or ball-shaped solidification.
A lash brush in accordance with the present invention includes a case, a rotatable shaft, a plurality of bristles and a reciprocating transmission mechanism, wherein the case comprises a ring wall, a bottom portion and an accommodating slot surrounded by the ring wall, the rotatable shaft comprises a first end portion and a second end portion, and the bristles are coupled to the first end portion of the rotatable shaft. The reciprocating transmission mechanism means for driving the rotatable shaft and includes a first unit and a second unit contacting against the first unit. The first unit comprises an actuating surface having a base surface and a plurality of spacing members alternately formed on the base surface, and the second unit comprises a contacting terminal sequentially contacting against each of the spacing members.
In this invention, by means of the contacting terminal in contact against each of the spacing members in sequence, when the rotatable shaft is driven to rotate by the reciprocating transmission mechanism, the rotatable shaft vibrates back and forth instantaneously. Accordingly, when a user holds the lash brush and applies the mascara onto the eyelashes, the motion of the rotatable shaft prevents glutinous mascara attached onto the eyelashes from forming into block-shaped or globular solidification.

When the user holds the lash brush 100 and applies the mascara to the eyelash, for the reason that the bristles 130 vibrate instantaneously along the axial line X, the time for the bristles 130 of the lash brush 100 in contact with the eyelash can be shorten. Therefore, when the glutinous mascara attached to the bristles 130 enables to separate instantaneously from the eye lash or contact instantaneously with the eye lash (the two actions are taken place one after another), the time for the bristles 130 in contact with the eyelash will last shortly so as to prevent the mascara attached to the eyelashes from forming into block-shaped or globular solidification. The disturbance for repetitively removing or applying the user's make up can be avoidable.
With reference to
The reciprocating transmission mechanism 140 is coupled to the rotatable shaft 120. In this invention, by means of (1) the driving unit 143 driving the first unit 141 and the rotatable shaft 120 into rotation along the axial line X, (2) the first unit 141 and the second unit 142 driving the rotatable shaft 120 into reciprocal linear motion along the axial line X, and (3) the contacting terminal 142a in contact against each of the spacing members 141c in sequence, the lash brush 100 enables to make the bristles 130 coupled to the rotatable shaft 120 vibrate instantaneously along the axial line X to prevent the time for the mascara in contact against the eyelashes from lasting too long. Therefore, the possibility for forming block-shaped or globular solidified mascara onto the eyelashes can be avoidable.

In this embodiment, by means of (1) the driving unit 143 driving the first unit 141 and the rotatable shaft 120 into rotation along the axial line X, (2) the first unit 141 and the second unit 142 driving the rotatable shaft 120 into reciprocal linear motion along the axial line X and (3) the contacting terminal 142a in contact against each of the spacing members 141c in sequence, the lash brush 100 enables to make the bristles 130 coupled to the rotatable shaft 120 vibrate instantaneously along a direction perpendicular to the axial line X to prevent the time for the mascara in contact against the eyelash from lasting too long. Therefore, the possibility for forming block-shaped or globular solidified mascara onto the eyelashes can be avoidable.
While this invention has been particularly illustrated and described in detail with respect to the preferred embodiments thereof, it will be clearly understood by those skilled in the art that it is not limited to the specific features and describes and various modifications and changes in form and details may be made without departing from the spirit and scope of this invention.
