     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0020]    The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed descriptions with reference to the attached drawings. 
         [0021]    Refer to  FIGS. 1 to 5  respectively for a schematic diagram of a portable water purifying bottle according to an embodiment of the present invention; an exploded view of a portable water purifying bottle according to an embodiment of the present invention; a cross section view of a portable water purifying bottle according to an embodiment of the present invention; a cross section view of a portable water purifying bottle having its plastic cup sleeve retracted according to an embodiment of the present invention; and another exploded view of a portable water purifying bottle according to an embodiment of the present invention. 
         [0022]    As shown in  FIGS. 1 to 5 , the present invention provides a portable water purifying bottle, that includes: an upper cover  100 , a filter core component  200 , and a plastic cup sleeve  300 . The upper cover  100  is provided with a water output port  110 . The filter core component  200  is disposed inside the upper cover  100 , and is located below the water output port  110 ; while the plastic cup sleeve  300  is sleeved into a lower portion of the upper cover  100 . In the present invention, water is stored in the plastic cup sleeve  300 . When a user desires to drink water, the portable water purifying bottle is put upside down, then squeeze the plastic cup sleeve  300 , such that water flows through and is filtered by the filter core component  200  to flow out from the water output port. By squeezing the plastic cup sleeve  300 , the water pressure in the portable water purifying bottle is raised, to expedite water output. 
         [0023]    In an embodiment of the present invention, the filter core component  200  includes: an upper end cover  210 , rotatably connected to a lower portion of the water output port  110 ; a lower end cover  220 ; a filter core outer shell  230 , disposed between the upper end cover  210  and the lower end cover  220 ; and a filter core  240 , disposed inside the filter core outer shell  230 . 
         [0024]    In an embodiment of the present invention, the portable bottle further includes: a water passage hole  211 , disposed on the upper end cover  210 , to connect to the water output port  110  and an inner chamber of the filter core  240 ; and a plurality of water input mesh holes  231 , disposed around a surrounding wall of the filter core outer shell  230 . The filter core  240  is of a barrel shape, water flows through the water input mesh holes  231  on the filter core outer shell  230  into the inner chamber of the filter core outer shell  230 , to reach the perimeter of the filter core  240 . Then, water is filtered through the filter core  240  and it enters into its inner chamber. The filtering material of the filter core  240  is certified by NSF (National Sanitation Foundation), and it can not only filter out bacterial, virus, and other contaminants, but it may also provide good taste, in achieving excellent filtering effect. Moreover, the filter core  240  can be replaced readily, so that user may select different filter cores  240  depending on the quality of water, to ensure safe drinking. 
         [0025]    In an embodiment of the present invention, the upper cover  100  includes a fixing sleeve  120 , rotatably connected to a lower end of the upper cover  100 , while the plastic cup sleeve  300  is sleeved around the lower portion of the fixing sleeve  120 . When adding water, all it has to do is to rotate and take off the fixing sleeve  120 , then pour water into the plastic cup sleeve  300 . 
         [0026]    In an embodiment of the present invention, inside an opening of the plastic cup sleeve  300  is provided with a protrusion ring  310  protruding inward; on an outer surrounding portion at a lower end of the fixing sleeve  120  is provided with a ring shape slot  121  acting in cooperation with the protrusion ring  310 ; and around the fixing sleeve  120  is disposed a decoration ring  400  pressing tightly against the opening of the plastic cup sleeve  300 , so that when rotating the decoration ring  400 . the fixing sleeve  120  is rotated synchronously. 
         [0027]    In an embodiment of the present invention, the portable water purifying bottle further includes: a bottle cover  500 , fastened onto the water output port  110 , to act in rotatable cooperation with the water output port  110 ; a decoration cover  600 , fastened onto the bottle cover  500 , so that when rotating the decoration cover  600 , the bottle cover  500  is rotated synchronously; a pull ring  700 , disposed above the bottle cover  500 , and penetrating out through a hole in a center of the decoration cover  600 ; and a block plate  710 , connected and fixed to a lower end of the pull ring  700 , to fasten to a lower side of the decoration cover  600 . The pull ring  700  is made of silicone, it can be put on a bag, or sleeved around the finger, for carrying it conveniently. 
         [0028]    In an embodiment of the present invention, in order to ensure overall tight seal of the portable water purifying bottle, in the upper cover  100  is provided with a first washer  130  pressing against the upper end surface of the fixing sleeve  120 ; on the top portion of the bottle cover  500  is provided with a second washer  510  pressing against the upper end surface of the water output port  110 . The upper end cover  210  and the protrusion mouth portion acting in rotation cooperation with the water output port, are sleeved around with tight seal rings respectively. 
         [0029]    In an embodiment of the present invention, the outer surfaces of the decoration cover  600 , the upper cover  100 , and the decoration ring  400  are processed by the slip resistance paint, to increase their friction, for the convenient handling by the hand, and in conformity with the design of ergonomics. The plastic cup sleeve  300  is made of semi-transparent silicone. That is a kind of high strength silicone, solid and endurable, so that the plastic cup sleeve  300  can be retracted into the portable water purifying bottle to facilitate easy carrying. 
         [0030]    The portable water purifying bottle of the present invention can be implemented through the following steps: in a water filling step, rotate the decoration ring  400 , to remove the decoration ring  400 , the fixing sleeve  120 , and the plastic cup sleeve  300  at the same time, next, pour in water into the plastic cup sleeve  300 , and then put the decoration ring  400 , the fixing sleeve  120 , and the plastic cup sleeve  300  onto the upper cover  100  at the same time; in a water drinking step, rotate the decoration cover  600 , to remove the decoration cover  600 , the bottle cover  500 , and the pull ring  700  at the same time, then, squeeze the plastic cup sleeve  300 , so that water is made to flow out from the water output port for drinking; and when the portable water purifying bottle is empty, or little water remains therein, the plastic cup sleeve  300  can be retracted to be stored in the fixing sleeve  120 .
