1. Field of the Invention
The present invention relates to a bath massage brush, and more particularly to an electric bath massage brush.
2. Description of the Related Art
Various types of bath massage brush are known in the prior art. One of which is disclosed in U.S. Pat. No. 8,745,807, titled “Scrubbing apparatus and method”. The massage brush is a small tool that fits in the palm of a user's hand, usually about the size of one's hand. It includes both thin and thick bristles made specifically for the scalp of the user. Using the massage brush to knead the scalp provides the same benefits of a massage, but using the brush while shampooing can also can help the hair. It can remove dirt in the hair and on the scalp, and distribute shampoo and conditioner. It can strengthen the roots of the hair and even the hair follicles where hair grows. Just as scalp massage can pull natural moisturizers out of the pores and onto your scalp, it also can draw those natural oils into the hair. This can leave the hair shiny, soft and strong.
SUMMARY OF THE INVENTIONObjectives of the invention are to provide an improved bath massage brush of simple structure, which is inexpensive in manufacture, light in weight, easily handled, fits into the palm of the hand of a user with facility and convenience, safe to use, and functions efficiently, effectively and reliably to massage any desired part of the body.
To achieve the foregoing objectives, the electric bath massage brush includes a hand-sized casing, a vibrating device and a control circuit device. The casing includes a case body and a lid. The case body defines at its front a massage surface and at its rear an opening that is covered by the lid. The case body is integrally formed at the massage surface with a plurality of bristles. Preferably, the bristles are made of a silicon material. The vibrating device is disposed within the casing and includes a motor and an eccentric cam connected to one end of a drive shaft of the motor for vibrating the massage surface upon rotation of the drive shaft. The control circuit device is also disposed within the casing and has a control circuit electrically coupled to the motor of the vibrating device for control the rotation of the drive shaft of the motor.
Preferred embodiments of the invention may have the following additional characteristics, either alone or in combination:
The control circuit device further includes a power supply and a rechargeable power source. The power supply has one end connected to the control circuit, and the other end to be connected to an outer power source. The rechargeable power source is connected to the control circuit for energizing the motor. A warning lamp, such as a light emitting diode (LED), may be mounted on the casing for indicating whether the power supply is shorted. The rechargeable power source includes a charging/discharging circuit and a battery. The charging/discharging circuit has one end connected to the battery, and the other end to the power supply in order to charge the battery. Moreover, the electric bath massage brush further includes a battery docking station. The docking station has a receptacle for receiving the casing of the electric bath massage brush and charging the battery of the same.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

The electric bath massage brush 200 of the second embodiment is substantially identical to that of the first embodiment, except that the electric bath massage brush 200 further includes a battery docking station 4. The docking station 4 has a receptacle 40 for receiving the casing 1 of the electric bath massage brush 200 and for charging the battery 332 of the rechargeable power source 33.
As best seen in
Referring now to
The electric bath massage brush 300 of the third embodiment is substantially identical to that of the first (or second) embodiment, except that a casing 1′ is provided in lieu of the aforementioned casing 1. The casing 1′ includes a case body 16 and a lid 17 coupled together. The case body 16 includes an inner shell 16b coupled with the lid 17 by a screw 18, and an outer shell 16a removably attached to the inner shell 16b, as will be understood later.
Specifically, the lid 17 defines a first annular groove 170 corresponding to an annular lip portion 161 of the outer shell 16a of the case body 16. With the annular lip portion 161 being engaged in the annular groove 170 of the lid 17, the outer shell 16a of the case body 16 may thus be joined to the lid 17 and removed therefrom easily. Preferably, the outer shell 16a together with its bristles 14 is made of a silicon material. Moreover, a second annular groove 167 is formed in between the inner shell 16b of the case body 16 and the lid 17. To add waterproof features, the outer shell 16a of the case body 16 further has an annular rib 162 extending inwardly and being fitted in the second annular groove 167. As such, the inner shell 16a of the case body 16 and the lid 17 together define a chamber 19 therebetween for accommodation of the vibrating device 2 and the control circuit device 3. And, the outer shell 16a of the case body 16 defines thereon said massage surface 140 and is integrally formed at the massage surface 140 with the bristles 14.
As described above, the present invention is directed to an electric bath massage brush of simple structure, and is inexpensive in manufacture, light in weight, easily handled. Moreover, the bath massage brush fits into the palm of the hand of a user with facility and convenience, safe to use, and functions efficiently, effectively and reliably to massage any desired part of the body.
