Abstract:
A waterproof valve includes a pivot, a valve comprising a sealing end and a floating end, the pivot is rotatably connected with the valve between the sealing end and the floating end, the sealing end is released to keep the valve open when the floating end is not contact with fluids, the sealing end is driven by the floating end to close the valve when the floating end is contact with fluids, to prevent or reduce the occurrence of short circuits caused by exposure to conductive fluids.

Description:
FIELD 
       [0001]    The subject matter herein generally relates to a waterproof valve and an electronic device using the waterproof valve. 
       BACKGROUND 
       [0002]    To meet specific function needs, some products, such as acoustic components, are needed to set openings to transmit sounds or airflow. At the same time, the openings on such products should be waterproof to ensure electrical safety. Therefore, providing a waterproof structure to prevent or reduce the occurrence of short circuits caused by exposure to conductive fluids would be beneficial.

     DETAILED DESCRIPTION 
       [0008]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. 
         [0009]    Several definitions that apply throughout this disclosure will now be presented. 
         [0010]    The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0011]      FIGS. 1 and 2  illustrate a waterproof valve in accordance with an embodiment. 
         [0012]    The waterproof valve can be adopted in opening  510  of an electronic device  1 , in order to prevent conductive fluids from flowing into electronic device  1 . In at least one embodiment, the electronic device  1  includes a housing  50 , the housing  50  defines a opening  510 , the opening  510  can be an air vent or a sound aperture of the electronic device  1 . 
         [0013]    The waterproof valve can include a pivot  10  and a valve  20 . In at least one embodiment, the pivot  10  can be a spindle, one end of the spindle is fixed on the inner surface of the housing  50 , the valve is rotatably connected with the other end of the spindle. 
         [0014]    One end of the valve  20  serves as a sealing end  201 , the sealing end  201  located on one side of the spindle and used to seal the opening  510  in needs. The other end of the valve  20  serves as a floating end  202 , the floating end  202  located on the other side of the spindle and used to detect fluids coming into the opening  510 . 
         [0015]    As shown in  FIG. 1 , when without fluids contacting the floating end  202 , the sealing end  201  is released under its own gravity to keep the valve open, which means the sealing end  201  is separated with the opening  510 , the electronic device  1  can work normally on this condition. A block bar  30  can be fixed on the housing  50  to limit the dock position of the floating end  202  when floating end  202  is without contact with fluids, to prevent the floating end  202  from swinging. 
         [0016]    As shown in  FIG. 2 , when fluids come to the floating end  202 , the floating end  202  rises under the effect of buoyancy, and the sealing end  201  is driven by the floating end  202  to seal the opening  510 , so as to prevent fluids from coming into the housing  50  by the opening  510 . 
         [0017]    The floating end  202  can be hollow to increase the buoyancy, a hollow floating end  202  could be lighter and more sensitive to fluids. 
         [0018]    The waterproof valve can further include a cushion  40 , the cushion  40  can be fixed with the housing  50  and resist against the outer surface of the valve. When the valve is driven by the floating end  202 , the cushion  40  is squeezed and deformed to retard the rotation of the valve. 
         [0019]    The cushion can be a substantially “O” shaped ring made of elastic materials, such as foam or silicone. 
         [0020]      FIGS. 3 and 4  illustrate a waterproof valve in accordance with another embodiment. 
         [0021]    As shown in  FIGS. 3 and 4 , the valve includes a first valve  210  and a second valve  220  symmetrically set to the first valve  210 . The pivot  10  includes a first pivot  110  corresponding to the first valve  210  and a second pivot  120  corresponding to the second valve  220 . The valve  210  and the second valve  220  are similar as the valve  20  shown in  FIGS. 1 and 2 . The first valve  210  includes a first sealing end  2101  and a first floating end  2102 , the first pivot  110  is rotatably connected with the first valve  210  between the first sealing end  2101  and the second floating end  2102 ; the second valve  220  includes a second sealing end  2201  and a second floating end  2202 . 
         [0022]    As shown in  FIG. 3 , when the first floating end  2102  and the second floating end  2202  are without contact with fluids, the first sealing end  2101  and the second sealing end  2201  are separated with the opening  510 , the electronic device  1  can work normally on this condition. 
         [0023]    As shown in  FIG. 4 , When the first floating end  2102  and the second floating end  2202  are in contact with fluids, the first sealing end  2101  and the second sealing end  2201  are driven by the first floating end  2102  and the second floating end  2202  to close the opening  510  together, so as to prevent fluids from coming into the housing  50  by the opening  510 . 
         [0024]    Each of the first sealing end  2101  and the second sealing end  2201  can define a engagement portion. When the first sealing end  2101  and the second sealing end  2201  are driven by the first floating end  2102  and the second floating end  2202  to close the opening  510 , the engagement portions reach an close contact with each other and seal the opening  510  together. The engagement portions can be a convex  2103  in the front end of the first sealing end  2101 , and a groove in the front end of the second sealing end  2201 . 
         [0025]    The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a mounting system for hard disk drive. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
