     DETAILED DESCRIPTION OF THE INVENTION 
       [0026]    A vacuum suction apparatus is provided by the present invention. Referring to  FIG. 1  to  FIG. 4 , a total of five embodiment structures are applied only for illustrating the present invention, with no intension to limit the scope of the invention. Each embodiment is illustrated as following. 
         [0027]    Referring to  FIG. 1  to  FIG. 4 , where a first embodiment of the present invention is shown, the embodiment comprises a cup body  1 , a joining member  2 , an adjust member  3 , a rubber sleeve  4 , and a seal assembly  5 . 
         [0028]    Therein, the cup body  1  is hollowed with two penetrable ends and provided with a first opening  11 . A neck portion  10  is disposed on the cup body  1  and provided with a penetrable second opening  12 . Two ends of the cup body  1  are penetrable with the first opening  11  and the second opening  12  provided thereon, respectively, while the first opening  11  is combined with the joining member  2 . 
         [0029]    The cup body  1  of the embodiment has a seat  13  on one end of the second opening  12 , wherein the seat  13  comprises an inner ring  130  integrally formed of the cup body  1 , with a sleeve ring  131  disposed within the inner ring  130  and an outer cover  132  combined to the inner ring  130 . The outer cover  132  covers the inner ring  130  and is coupled therewith. One stretch sleeve  14  is disposed on one end of the cup body  1  adjacent to the second opening  12 . 
         [0030]    The joining member  2  is screwed to the neck portion  10 , thereby sealing the first opening  11 . When the joining member  2  seals the first opening  11 , air is prevented from flowing in or out from the first opening  11 . In the embodiment, one stretch portion  21  extends outward from the joining member  2  to form a block portion  211 . The stretch portion  21  is allowed to be screwed to the adjust member  3 . An air permeable gap is defined between the adjust member  3  and the stretch portion  21 . Two longitudinal air channels  210  are provided to the stretch portion  21 , such that the air channels  210  facilitate the air flow between the adjust member  3  and the cup body  1 . In case the adjust member  3  is tightly screwed by the stretch portion  21 , the bottom of the adjust member  3  resist against the upper part of the block portion  211 . Also, the adjust member  3  is allowed to be unscrewed and loosened in order to adjust the gap between the bottom of the adjust member  3  and the block portion  211 . 
         [0031]    The rubber sleeve  4  is hollowed and inserted into the cup body  1 . In the embodiment, the rubber sleeve  4  is disposed in the cup body  1  and provided with an input end  41  having a tapering bore diameter. The bore diameter of the input end tapers against the hollowed part of the rubber sleeve  4  for simulating a female vaginal orifice, such that the male genital organ of the user is allowed to enter from the input end  41 . The rubber sleeve  4 , which is hollowed and inserted into the cup body  1 , is provided with a partition membrane at one end adjacent to the first opening  11 , wherein the partition membrane  40  is integrally form on the rubber sleeve  4 . Therein, water is allowed to pass the partition membrane  40 , such that the partition membrane  40  is able to prevent the semen from spilling out of the rubber sleeve  4 . 
         [0032]    A bottom part  42  is disposed at the input end  41  of the rubber sleeve  4  and confined between the ring sleeve  131  and the outer cover  132 . The ring sleeve  131  is provided with at least one sleeve inner diameter, capable of adjusting the inner bore diameter of the input end  41 . The ring sleeve  131  is able to temporarily prevent the blood of a male genital organ A from flowing back, thereby maintaining the erection duration of the male genital organ A. Also, by mounting around the root part of the male genital organ A with at least one sleeve inner diameter, different tightness demands of the user are met. 
         [0033]    The seal assembly  5 , which in the embodiment extends from the inner side of the stretch portion  21 , comprises a stop member  50 , a membrane seat  51 , a membrane  52 , a jacket  53 , and a jacket membrane  54 . 
         [0034]    Therein, the stop member  50  is provided with an upper partition  501 , the upper partition  501  has an upper concave  502  and an upper air bore  503 . 
         [0035]    The membrane seat  51 , in the embodiment, is an integral component of the stretch portion  21  and made of a rigid material, wherein the membrane seat  51  has a lower partition  510  disposed underneath the upper partition  501 . The lower partition  510  is provided with a lower concave  511  and a lower air bore  512 . A membrane chamber  513  is disposed between the lower concave  511  and the upper concave  502 . The lower air bore  512 , in the embodiment, is smaller than the upper air bore  503 . 
         [0036]    The membrane  52  is disposed in the membrane chamber  513 . The top surface and the bottom surface of the membrane  52  are provided with plural convex dots, respectively, and also provided with a slit  520 , such that air is allowed to enter or be locked from either side thereof. When the adjust member  3  rotates, bottom surface of the stop member  50  thus arises or lowers correspondingly. The membrane  52  is able to arise freely. The membrane member  52  is made of a flexible material, and plural convex dots are disposed on the top surface and the bottom surface thereof, respectively, wherein the lower convex dots  522  are smaller and lower than the upper convex dots  523 . When the membrane  52  is placed in the membrane seat  51 , the smaller lower convex dots  522  of the membrane  52  defines a gap against the membrane seat  51  and is thereby presented in a floating-like status. When the adjust member  3  rotates, the bottom surface of the stop member  50  thus arises or lowers correspondingly, thereby optionally adjusting the inflow or out flow of air inside the cup body  1 . 
         [0037]    The membrane  52  of the present invention defines a gap by use of the convex dots thereon resisting against the stop member  50 , such that when the adjust member  3  is adjusted to cause the stop member  50  to arise and lower, the membrane  52  correspondingly arises and lowers. As a result, the present invention is able to accurately control the inflow and outflow of the air, thereby altering the intensity of the negative pressure in the cup body  1 . 
         [0038]    The jacket membrane  54  is disposed on the bottom part of the jacket  53 , wherein the jacket  53  is made of a flexible structure, so as to mount around the bottom of the membrane seat  51  and be placed with the joining member  2 . The jacket membrane  54  is provided with a slit  540 , such that the jacket membrane  54  keeps the clearance of the membrane chamber  513 , and at the same time allows the air in the cup body  1  to pass through the slit  540  of the jacket membrane  54 . 
         [0039]    During the operation of the vacuum suction apparatus of the embodiment provided by the present invention, male user holds the cup body  1  to mounts the cup body  1  around the male genital organ A, so as to operate the present invention in a manner of reciprocating thereon. Air in the cup body  1  passes from the first opening  11  through the jacket membrane  54  of the seal assembly  5 , and then through the lower air bore  512  into the membrane chamber  513 . The air pushes the membrane  52  into the upper concave  502 , causing the membrane  52  to deform upward, thereby opening the slit  520  and enabling the air to pass the upper air bore  503  through the slit  520 . The air in the cup body  1  also forms a resistance to the male genital organ A, while the air outflows from the middle of the joining member  2  and the neck portion  10 . On the other hand, when the male genital organ A is withdrawn toward the input end  42 , the air reversely flows back through the abovementioned structures into the cup body  1 . When the air passes the membrane  52 , the membrane  52  is pulled downward into the lower concave  511 , causing the membrane  52  to deform downward, thereby opening the slit  520  and enabling the air to pass through the lower air bore  512  and the jacket membrane  54  into the cup body  1 . 
         [0040]    Thus, advantages of the present invention are obvious. The rotation of the adjust member  3  accurately adjust the gap between the adjust member  3  and the membrane seat  51  (as known as the stretch portion  21 ). With the membrane  52  allowing the air to pass through the slit  520 , together with the difference between the upper convex dots  523  and the lower convex dots  522  of the membrane  52 , the membrane  52  is thereby allowed to arise and lower for controlling the mutual airflow, such that when the male genital organ A is withdrawn in the cup body  1 , the negative pressure therein produced an attraction to facilitate the erection of the male genital organ A. Furthermore, the negative pressure produced during the male genital organ A withdrawn and the resistance produced during the male genital organ A inserted to the cup body  1  simulates the reciprocation of the male genital organ A in a tight vagina. Therefore, the user is allowed to experience a virtual sexual intercourse. 
         [0041]    In addition, during the user reciprocating the cup body  1 , with the stretchable characteristic of the stretch sleeve  14 , traveling distance of the male genital organ A in the cup body  1  is prolonged. Thus, the stretch sleeve  14  is applied to compress the air, so as to produce a negative pressure during the male genital organ A being withdrawn and inserted, thereby aiding the male genital organ A of the user capable of slightly erecting to be gradually sucked into the cup body  1  for carrying out the reciprocation. 
         [0042]    Particular embodiments of the invention have been described in detail for purposes of illustration, so that various modifications and enhancements may be made without departing from the spirit and scope of the invention. 
         [0043]    With the detailed explanation, skilled people in the field of the present invention are able to accomplish the present invention. Such contents meet the requirements of Patent Act, so that the present patent application is filed.
