BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention is a back scrub brush. More specifically, the present invention is an electric back scrub brush.
2. Description of the Related Art
Typically bath back scrub brushes are not an electrical appliance and are not convenient enough to use outside the bathroom because they are not portable. And bath back scrub brushes typically have only a circular rotating motion.
The present invention is a portable practical brush that may be utilized anywhere. And it has a one-way rotational motion along the vertical axis of a user's back, so it simulates the scrubbing motion of a person when they clean their back with a back scrub brush.
BRIEF SUMMARY OF THE INVENTIONThe present invention is a back scrub brush. More specifically, the present invention is an electric back scrub brush.
The electric back scrub brush includes a support handle housing having a push button control switch disposed on an outer surface of the support handle housing, a first spur gear coupled to an output end of a motor drive shaft, the first spur gear is operatively connected to a second spur gear which is coupled at a first end of a central drive shaft disposed in a center portion of a neck and a motor energized by a battery disposed within the support handle housing and a second end of a central drive shaft is coupled to a first bevel gear. The electric back scrub brush also includes a brush support housing coupled to the support handle housing, the brush support housing includes the neck and a head and a bristle roll that is protected by a cover member disposed over the head covering the bristle roll.
The electric back scrub brush has a horizontal bristle roll which rotates about an axis perpendicular to the longitudinal axis of the neck of the electric back scrub brush, which runs parallel to the axis of the back of a user when utilized by a user. The electric back scrub brush operates by the battery energized motor and includes two detachable portions. The electric back scrub brush may rotate and move along the axis of the user's back perpendicularly, is a self-operated appliance and is a portable appliance and may be easily transported anywhere.
It is an object of the present invention to provide an electric back scrub brush that has a one-way rotating or rolling motion that simulates a movement of a user scrubbing another user's back.
It is an object of the present invention to provide an electric back scrub brush that is portable and may be utilized outside of a bathroom.
It is an object of the present invention to provide an electric back scrub brush that operates by an internal battery energized motor.
The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawings in which like references denote similar elements, and in which:
Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some of the described aspects. For purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the illustrative embodiments. However, it will be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well-known features are omitted or simplified in order not to obscure the illustrative embodiments.
Various operations will be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention however the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation.
The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment, however, it may. The terms “comprising”, “having” and “including” are synonymous, unless the context dictates otherwise.
The electric back scrub brush 100 includes a support handle housing 110 and a brush support housing 120 with a neck 122 and a head 124. The support handle housing 110 is coupled to the brush support housing 120. More specifically, the brush support housing 120 may be detached from the support handle housing 110. A push button control switch 112 may be disposed on an outer surface 114 of the support handle housing 110.
The head 124 has a plurality of bristles 124a disposed on the head 124 that extend radially and outwardly to form a bristle roll 124b. A second end 170b of the central drive shaft 170 may be coupled to a first bevel gear 180. The first bevel gear 180 may be coupled to a second bevel gear 185 which may be coupled to the second end 125b of the bristle roll shaft 125. There may be a first pulley 190 coupled to the first end 125a of the bristle roll shaft 125, which may be coupled to the second pulley 192 by a belt 194.
The head 124 has a plurality of bristles 124a disposed on the head 124 that extend radially and outwardly to form a bristle roll 124b.
The bristle roll 124b may be protected by a cover member 126 which may be disposed over the head 124 covering the full length of the bristle roll 124b.
The cover member 126 protects the bristle roll 124b of the electric back scrub brush 100 to prevent skin and hair on a user's back (not shown) from being damaged from the bristles 124a during the rotating brushing motion of the electric back scrub brush 100 against a user's back (not shown).
The rotating power of the electric back scrub brush is generated by the battery energized motor disposed in the hollow cavity of the handle. The rotating power of the motor is transferred through the spur gear system from the output end of the motor drive shaft to the central drive shaft of the neck. The electric back scrub brush includes two spur gears. The primary smaller spur gear is attached at the output end of the motor drive shaft. The secondary bigger spur gear is attached at the frontal end of the central drive shaft. The rotating power is provided to the central drive shaft through the bevel gear system causing the bristle roll shaft to rotate. The rotating power of the drive shaft transfers to the bristle roll shaft through the belt and pulley system causing the bristle roll shaft to rotate. The belt and pulley system includes two pulleys of differing diameter disposed separately from each other at the head of the electric back scrub brush. The smaller pulley is attached at the first end of the bristle roll shaft. The bigger pulley is attached at the second end of the bristle roll shaft. Both pulleys are operatively connected by a belt.
The electric back scrub brush is utilized for cleaning the back of a user's body conveniently and effectively by its rolling motion anywhere, not only in the bathroom. Because of the angle or bended feature of the head of the electric back scrub brush, it is also used as a back massage appliance.
While the present invention has been related in terms of the foregoing embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
