Generally, odor can directly and strongly influence people, for example, many people can release their tension through aromatic odor such as perfumes or essential oils, to improve the sleep quality. 
     Pillow is one of the important bedding and near a nose when sleeping. A conventional pillow with an aroma has an aromatic package disposed inside a pillowcase such as tea leaf package, wooden material package, etc. A softness of the pillow affects a comfort of pillow when a head and a neck pillows on. The aromatic package of the conventional pillow is hard to adjust hardness and with uneven structure so as to influence the comfort of the pillow. 
     The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a pillow, in which the pillow is an aromatic pillow. 
     To achieve the above and other objects, a pillow is provided, including an inner core; a cover, covering the inner core, including a base layer which is integrally formed of one piece by injection molding and an aroma unit which is distributed within the base layer. 
     To achieve the above and other objects, another pillow is provided, including an inner core; a cover, covering the inner core, including a base layer which is integrally formed of one piece by injection molding and an aromatic layer covering the cover. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIGS. 1 to 5  show a pillow according to a preferred embodiment of the present invention. The pillow  1  includes an inner core  10  and a cover  20 . 
     The inner core  10  is a latex inner core, a memory foam inner core or a plastic foam inner core. The cover  20  covers the inner core  10 , and the cover  20  can only cover the partial inner core  10 , for examples, the cover  20  only cover one side of the inner core  10  or encase the inner core  10  completely. In this embodiment, the cover  20  encases the inner core  10  completely. The cover  20  includes a base layer  21  which is integrally formed of one piece by injection molding and an aroma unit  22  which is distributed with the base layer  21 . As shown in  FIG. 4 , the aroma unit  22  is disclosed as dot structures within the base layer  21 . In this embodiment, the base layer  21  is a plastic layer such as an un-foamed plastic layer. Thus, the cover  20  not only can release aroma, but can provide a tight combination of the aroma unit  22  and the base layer  21 . Besides, the pillow  1  does not be influenced a comfort by the cover  20  when being pillowed. In this embodiment, the aroma unit  22  is aromatic liquid such as an essential oil or aromatic powder such as dry natural plant powder and artificial aromatic powder. Besides, the cover  20  can be changed in accordance with the needs of the aroma, for examples, to change the cover  20  with the different aroma. 
     The pillow  1  further includes an aromatic layer (not shown) covering the cover  20 . Wherein, the aromatic layer (not shown) and the aroma unit  22  can be different from each other in aroma, so as to mix different aromas, or to strong the concentration of the aroma by using the same aroma. 
     In embodiment, the cover  20  is a casing, and includes a chamber  24  and an opening  25  communicated with the chamber  24 , the inner core  10  is received within the chamber  24 , the pillow  1  further includes an enclosure structure  40  disposed on the cover  20 , the enclosure structure  40  is openable and closable to selectively open and close the opening  25 , so as to control the open statement of the opening  25 . Preferably, the enclosure structure  40  is a zipper, and also can be a male-female buckle. Wherein, at least one side of the cover  20  has a plurality of venting structures  23  arranged thereon, so as to elevate a breathing activity of the pillow  1 . Moreover, it can improve a diffusion effect of the aroma by pressing the pillow  1  to vent out air through the plurality of venting structures  23 . In this embodiment, each of the venting structures  23  and the cover  20  are integrally formed of one piece. In other embodiment, the venting structures  23  can be disposed on the cover  20  such as a check valve structure. 
     The pillow  1  further includes a pillowcase  50 , the pillowcase  50  covers the cover  20 . In this embodiment, the pillowcase  50  covers the cover  20  and the inner core  10 , the cover  20  is disposed between the pillowcase  50  and the inner core  10 . In this embodiment, the pillowcase  50  is a fabric member, so as to elevate a breathing activity. 
     Please refer to  FIGS. 6 to 7  show another preferred embodiment of the present invention. As compared with the preferred embodiment mentioned above, the cover  60  includes a base layer  61  which is integrally formed of one piece by injection molding and an aromatic layer  62  covering the base layer  61 . Thereby, the cover  60  can release the aroma. In this embodiment, the aromatic layer  62  is integrally formed as a part of a surface layer of the base layer  61  with an aromatic permeating thereinto. Specifically, the base layer  61  is soaked in the aromatic liquid and covered the aromatic layer  62  thereon. Thus, the aromatic layer  62  can cover on the surface of the base layer  61  completely. In other embodiment, the aromatic layer  62  can also be sprayed or coated on the base layer  61 . 
     Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
