Title: Separable auxiliary device of milk absorber

Description:
FIELD OF THE INVENTION  
      The present invention relates to milk absorbers, and particular to a separable auxiliary device of a milk absorber, in that the auxiliary device is separable from the milk absorber for storage and carry and the suction force is adjustable so that the user will feel easy.  
     BACKGROUND OF THE INVENTION  
      Currently, milk absorber is used to suck milk from a woman breast so as to collect milk for feeding child. In the prior art, the milk absorber has a cover which is combined with a container. The cover has a cup one end of which covers the breast of a woman. Another end of the cup is connected to an outlet of the milk absorber for exhausting air. The outlet is connected with an air bag. When the cup covers the breast, the air bag is compressed so as to generate a suction force to suck the milk from the breast. The sucking milk will flow into the container. This milk absorber causes the woman to press the air bag using by hand, but the operation needs a great force and a longer time is necessary. The air bag is directly connected to the milk absorber and is inseparable. Thereby, it cannot be carried easily.

      In use, the milk absorbing unit  1  covers a breast of a woman. Then the suction unit  3  is actuated for sucking milk from the breast. In the sucking process, if the breast feels uneasy, the adjusting unit  2  is used to adjust the suction force or an adjusting button  301  on the suction unit  3  is used to adjust the suction force so that the user may feel easy. Thereby, the milk absorbing unit can be used to breasts of various sizes.  
      The above mentioned milk absorbing unit  1  has a cover  11 . The cover  11  is combined with a container  12  for collecting milk. The cover  11  includes a cup  13  which can cover the breast of a woman.  
      The adjusting unit  2  is arranged on the cover  11 . The adjusting unit  2  has a casing  21 . A tube  211  is in the casing  21 . One end of the tube  211  has an inlet  212 . Another end thereof has an outlet  213  which is connected to the transmission tube  33 . An interior of the casing  21  has a receiving space  214  which is communicated to the tube  211 . An interior of the receiving space  214  is arranged with an elastic element  22  which is selectable from one of a spring, a reed and a rubber. The elastic element  22  has a plug  23 . A drain-proof element  24  made of rubber is arranged on the plug  23 . A cap  25  is arranged on the drain-proof element  24 . A combining portion  251  is arranged on the cap  25 , which is communicated to the receiving space  214 . The cap  25  is formed with an adjusting hole  252  and an operation hole  253  which are communicated to the receiving space  214  and external space. A rod portion  261  is arranged into the operation hole  253 . A key  26  is arranged on the rod portion  261 .  
      An internal of the suction unit  3  has an air chamber  31 . One end of the air chamber  31  is formed with at least one inlet  32  which is connected the transmission tube  33  and another end thereof has a first channel  34  which is communicated to the air chamber  31 . A lateral side of the first channel has an outlet  341 . One end of the first channel  34  is connected to a second channel  35 . The first channel  34  is not communicated to the second channel  35 . The second channel has an inlet  351  and an exhausting hole  352 . At least one rod body  36  is connected at an outer side of the air chamber  31  at one end thereof. In this embodiment, two bodies  36  are illustrated. An air bag chamber  37  made of rubber is installed at a predetermined position of the rod body  36 . The air bag chamber  37  is connected between the outlet  341  of the first channel  34  and the inlet  212  of the second channel  35 . Another end of each rod body  36  has a driven element  38  made of magnet. A driving element  39  is installed in the suction unit  3  at a position corresponding to the driven element  38 . The driving element  39  is formed by a silicon steel sheet  391  and a coil  392  for generating magnetic field to drive the driven element  38  to further drive the rod body  36  to move. Thus, the air bag chamber  37  is compressed between the outlet  341  of the first channel  34  and the inlet  212  of the second channel  35 . Thus, air can flow into the inlet  32  of the air chamber  31  for sucking milk. Furthermore, the suction unit  3  has an adjusting button  301  for adjusting the current of the internal circuit of the suction unit  3  so as to adjust the sucking force of the suction unit  3 . Thereby, women of various sizes of breasts can use the present invention and the breast milk can be sucked at a short time period.  
      With reference to  FIGS. 1, 3  and  4 , the operation of the present invention is illustrated. In use, one end of the transmission tube  33  is connected to the outlet  213  of the adjusting unit  2  and another end of the transmission tube  33  is connected to the inlet  32  of the suction unit  3 . Then the cup  13  of the milk absorbing unit  1  covers the breast of a woman. When the suction unit  3  is actuated, the milk flows into the container  12  of the milk absorbing unit  1  and air flows into the inlet  212  of the tube  211  of the adjusting unit  2 . Then air flow through the transmission tube  33  to the interior of the suction unit  3 .  
      If in the sucking process, the woman feels uneasy due to a too large sucking force. The woman can press the key  26  of the adjusting unit  2  so that the rod portion  261  pushes away the plug  23 . External air flows into the receiving space  214  of the adjusting hole  252  of the cap  25  so as to reduce the sucking force between the breast and the cup  13 . Thereby, in the sucking process, the women will not feel uneasy.  
      If the breast is too large or too small, or the milk is too much, the adjusting button  301  of the suction unit  3  can be rotated for adjusting the sucking force of the suction unit  3 . Thereby, the milk can be sucked out in a short time period.  
      Moreover, when the milk absorbing unit  1  is not used, the transmission tube  33  is separated from the adjusting unit  2  and the suction unit  3  for storage and transfer.  
      Furthermore, a plurality of inlets  32  can be formed on the suction unit  3  so that the separable auxiliary device for a milk absorber is used to suck milk from two breasts at the same time. Or two milk absorbing units  1  are connected together to be used for two women.  
      The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
