       FIGS.  11  to  13    are inner structure diagram of the eleventh implementation mode of a kind of sleeping pillow complying with the spinal medical theories in the present invention. With reference to  FIG.  11   - FIG.  13   , the sleeping pillow includes the pillow case and fillers filled in the pillow case. The pillow case includes upper layer cloth  11 , lower layer cloth  12 , vertical cloth  13 , bottom layer cloth  14  and vertical partition cloth  15 . Preferably, fillers are any or several of PE hoses, buckwheat hulls, cassia seeds and silkworm excrement. Of course, other normal materials can also be used. 
     The upper layer cloth  11  is sewed with the lower layer cloth  12 , and the vertical cloth  13  is sewed on both sides of the upper layer cloth  11  and the lower layer cloth  12 . The side of partition cloth  15  is respectively sewed with the upper layer cloth  11 , vertical cloth  13  and lower layer cloth  12 , which separate the space enclosed by upper layer cloth  11  and lower layer cloth  12  into independent head bearing area  16  and neck bearing area  17 . 
     The head bearing area  16  has the face-up sleeping head bearing area  16   a  dented in the middle and the side sleeping head bearing area  16   b  whose both sides are higher; neck bearing area  17  has the face-up sleeping neck bearing area  17   a  set in the middles and the side sleeping neck bearing area  17   b  set on both sides of the face-up sleeping neck bearing area  17   a . The height of the side sleeping neck bearing area  17   b  is no lower than the face-up sleeping neck bearing area  17   a . When the sleeping pillow of the present invention is normally used, the height of the side sleeping neck bearing area  17   b  must be higher than the face-up sleeping neck bearing area  17   a , with two ways for adjusting the heights of the two: one is by the effect of height restriction of the pillow case, that is, the pillow case has a lower sewing height than that of face-up sleeping neck bearing area  17   a ; the other is that you can sew the face-up sleeping neck bearing area  17   a  and the side sleeping neck bearing area  17   b  at the same height, but the saturation of fillers of the two is different. If the way of adjusting height of fillers is used, the heights of different subsections of the pillow case in neck bearing area  17  may be the same. Isolated and independent head bearing area  16  and neck bearing area  17  can effectively avoid movement of fillers between the two in the pillow case to ensure the stability of pillow shape. 
     What is specially described is that the vertical cloth  13  in this embodiment can be made of single layer cloth, and can be made of multilayer cloth with inside cloth. If it is multilayer cloth, then the inside cloth must be sewed with the vertical partition cloth  15 , so there will be no sewing threads in the outer layer of the vertical cloth  13 , which ensures the overall beauty of the pillow and the effect on forming and shaping of vertical cloth  13  done by sewing threads. 
     The head bearing area  16  is used for supporting the head while a person is sleeping. It is provided with several pieces of connecting cloth connecting the upper layer cloth  11  and lower layer cloth  12 . The head bearing area  16  forms the face-up sleeping head bearing area  16   a  and the side sleeping head bearing area  16   b  with the effect of pulling force of the connecting cloth. In this implementation mode, connecting cloth includes horizontal connecting cloth  16   c  and vertical connecting cloth  16   d . Of course, horizontal connecting cloth  16   c  and vertical connecting cloth  16   d  do not have to satisfy the absolute vertical relationships. Only making the upper layer cloth  11  form proper height dent will do. 
     The connecting cloth of the head bearing area  16  is designed using half open subsection so that inner fillers can move in the supporting area of the face-up sleeping and the side sleeping. This adaptable movement can not only make a person feel comfortable, but also have some massage effect on the scalp. 
     The neck bearing area  17  is used to support the neck while a person is sleeping. It has at least two pieces of vertical subsection cloth  17   c  that is totally separated or partly separated. The neck bearing area  17  forms the face-up sleeping neck bearing area  17   d  and the side sleeping neck bearing area  17   e  with the pulling force of the vertical subsection cloth  17   c , in which the face-up sleeping neck bearing area  17   a  corresponds with the face-up sleeping head bearing area  16   a  and the side sleeping neck. 
     The supporting area  17   b  corresponds with the side sleeping head bearing area  16   b . If a totally separated structure is used for the vertical subsection cloth  17   c , then fillers in different neck bearing areas cannot move in the neighboring neck bearing areas so as to ensure the shape of the pillow; if the partly separated structure is used for the vertical subsection cloth  17   c , then fillers in different neck bearing areas cannot move towards each other. This adaptable movement has helped improve the comfort of the sleeping pillow to some extent. 
     In order that human head and neck fit the sleeping pillow, the height of the dent center of the face-up sleeping head bearing area  16   a  in the present invention must be lower than that of face-up sleeping neck bearing area  17   a , while the height of the side sleeping head bearing area  17   a  must be lower than that of the side sleeping neck bearing area  17   b . Therefore, whether human body is in face-up sleeping or side sleeping state, the present invention can perform adjustment so that the sleeping pillow making body pressure balanced will make human body feel naturally comfortable. 
     The bottom layer cloth  14  is sewed below the lower layer cloth  12 , and is sewed with the vertical cloth  13 . The interlayer between the bottom layer cloth  14  and lower layer cloth  12  is used to place height adjusting cushion (not shown in Figure). The height adjusting cushion can make the sleeping pillow suitable to persons with different shoulders to avoid stiff neck or harm to cervical vertebra due to too high or too low a sleeping pillow. 
     The lower layer cloth  12  is provided the first opening  12   a  with zippers at the location of the head bearing area  16   a . The first opening  12   a  is used to place fillers towards the head bearing area  16 . The neck bearing area  17  is provided with the second opening  12   b  with zippers. The second opening  12   b  is used to place fillers for the neck bearing area  17 . The bottom layer cloth  14  is provided with the third opening  14   a  with zippers.
