## Background
FIELD OF INVENTION
The present invention relates to skin treatment, and more particularly to a skin treatment apparatus which is capable of performing micro-dermabrasion to a user's skin, so as to allow the user's skin to regenerate for cosmetic purpose.
DESCRIPTION OF RELATED ARTS
A conventional skin treatment system, such as a skin treatment system for performing dermabrasion skin treatment, usually comprises a skin treatment apparatus, a fluid reservoir connected to the skin treatment apparatus, a vacuum reservoir also connected to the skin treatment apparatus, and a vacuum source connected to the vacuum reservoir for vacuuming the skin surface during the course of the treatment. The connections between the skin treatment apparatus, the vacuum reservoir, and the fluid reservoir are accomplished by a plurality of tubes which are responsible for transmitting fluid and air so as to form a vacuum loop within the skin treatment system.
The skin treatment apparatus usually comprises a handle body and a skin treatment head formed at a front end portion of the handle body, wherein a user is able to manually hold the handle body and contact the skin treatment head with a predetermined skin area for performing abrasive or any other skin treatment. Very often, the tubes connecting the skin treatment apparatus with the vacuum reservoir and/or the fluid reservoir are attached on the skin treatment apparatus at a position in the vicinity of the skin treatment head.
This brings a problem when a user is manually holding the skin treatment apparatus for performing a skin treatment procedure because the tubes attached on the skin treatment head are likely to hinder a free movement thereof and the user is unable to freely move the skin treatment head on a predetermined skin. When the skin treatment apparatus moves over an extended distance on the skin, the tubes may entangle with each other and this adversely affect the supply of fluids and the formation of the vacuum condition within the skin treatment system.
Moreover, conventional skin treatment system usually does not have accurate and visible indications as to the pressure level developed within the skin treatment system when it is operated to perform a skin treatment procedure. Thus, it is hard for a user or operator of the conventional skin treatment system to manually observe a pressure developed within the vacuum loop and make a corresponding adjustment.
SUMMARY OF THE PRESENT INVENTION
The invention is advantageous in that it provides a skin treatment apparatus in which the fluid inlets are formed at a distance from the handle body so that when a user is performing a skin treatment procedure, the treatment head is not interfered by the fluid inlets and the tubes attaching thereto.
Another advantage of the invention is to provide a skin treatment apparatus in which a user is able to manually hold the handle body for freely performing skin treatment without entangling the tubes transmitting fluids to and from the skin treatment apparatus.
Another advantage of the invention is to provide a skin treatment apparatus in which is capable of performing dermabrasion skin treatment in an optimal manner in the sense that the abrasion can be stably performed at a very low rotational speed by a treatment head.
Another advantage of the invention is to provide a skin treatment system comprising the skin treatment apparatus in which a user is able to monitor and adjust a pressure developed within the skin treatment system so as to optimize and fully control the skin treatment procedure.
Another advantage of the invention is to provide a skin treatment apparatus comprising a treatment head which is capable of defining a vacuum treatment chamber for effectively circulating a predetermined amount of skin treatment fluid so as to maximize an efficiency and effectiveness of the corresponding skin treatment procedure.
Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.
According to the present invention, the foregoing and other objects and advantages are attained by providing a skin treatment apparatus, comprising:
a handle body having a front end portion, a rear end portion, and a receiving cavity formed between the front end portion and the rear end portion;
a driving unit received in the receiving cavity of the handle body;

a treatment cap detachably attached on the supporting member to form a treatment cavity between the supporting member and the treatment cap, wherein the treatment cap has a through cap opening formed thereon;
a treatment shaft rotatably connected to the driving unit and extended from the driving unit into the treatment cavity;
an abrasion head integrally formed at a free end of the treatment shaft in such a manner that when the treatment shaft is driven to rotate, the abrasion head is also driven to rotate with respect to the handle body, wherein a length of the treatment shaft and the abrasion head is slightly shorter than a length of the treatment cap so as to form a treatment gap defined between the abrasion head and the cap opening; and
an inlet arrangement, which comprises a fluid inlet and a vacuum inlet formed at the supporting member of the treatment head unit for providing a predetermined amount of skin treatment fluid in the treatment cavity, wherein the inlet arrangement is arranged to generate a vacuum effect in the treatment cavity so that the skin treatment fluid is capable of being effectively and efficiently delivered to and sucked out of the treatment cavity while the abrasion head operates to treat user's skin.
