Title: Electronic device including fluid detecting device

Description:
CLAIM OF PRIORITY 
     This application claims priority under 35 U.S.C. §119(a) to Korean Application Serial No. 10-2015-0026690, which was filed in the Korean Intellectual Property Office on Feb. 25, 2015, the entire contents of which are hereby incorporated by reference. 
     TECHNICAL FIELD 
     The present disclosure generally relates to an electronic device and, in particular, to an electronic device that is configured to determine a condition of the electronic device including, for example, whether the electronic device has been polluted or waterlogged. 
     BACKGROUND 
     An electronic device refers to a device that conducts a specific function according to a program equipped therein, such as, for example, a digital organizer, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image/sound device, a desktop/laptop computer, or a navigation system for a vehicle, including home appliances. The above-mentioned electronic devices may output stored information, for example, as a sound or an image. As the integration degree of the electronic devices have increased and ultrahigh speed and large capacity communication has been popularized, various functions have been recently equipped in a single mobile communication terminal. The electronic devices may perform a variety of function including in addition to a communication function. For example, the electronic devices may also perform such function as: an entertainment function (e.g., a game), a multimedia function (e.g., music/video image reproduction), a communication and security function for mobile banking, a schedule management function and an electronic wallet function. 
     As various functions have been integrated into a single electronic device, the electronic device may be used to assist in many daily activities. Such devices are convenient because they can be carried on ones person and enable many activities to be performed, as the single electronic device performs many and varied functions typically performed by standalone devices, such as a mobile communication terminal, provides a communication function, such as voice call or message, a digital organizer function, such as schedule management, a multimedia function, such as enjoying music/video images, and an office function that enables preparation of a memo or a document, a user may. 
     SUMMARY 
     As using an electronic device while carrying the electronic device becomes the norm, the operating environment of the electronic device may be frequently changed. For example, the operating environment of the electronic device may be variously changed according to an indoor or outdoor environment or the weather at the time when the user engages in an activity. With respect to pollution or damage of the electronic device that is caused due to such environmental changes, determining a reason for the pollution or damage may enable the repair or the like of the polluted or damaged electronic device to be further facilitated. In order to determine whether the electronic device is simply polluted by moisture or whether the electronic device is waterlogged, for example, a fluid detecting device, which uses a material to be discolored by moisture, may be used. 
     As the size and weight of electronic devices are gradually reduced, arranging such a fluid detecting device may have difficulties. For example, in the case of an electronic device formed in a unibody structure, when such a fluid detecting device is arranged on the exterior of the electronic device, the external appearance of the electronic device may be degraded. In addition, when such a fluid detecting device is arranged within the electronic device, it may be difficult to observe the fluid detecting device unless the electronic device is disassembled. For example, since the electronic device formed in a unibody structure is difficult to disassemble not only by the user, but also by a repair/maintenance service provider, there may be difficulty in determining the reason for pollution or damage even if such a fluid detecting device is provided. 
     Therefore, various embodiments of the present disclosure provide an electronic device including a fluid detecting device that is useful for easily determining the reason for the pollution or damage of the electronic device. 
     In addition, various embodiments of the present disclosure provide an electronic device including a fluid detecting device that enables visual observation even if the electronic device is not disassembled. 
     Further, an electronic device may include a fluid detecting device that enables easy visual observation without affecting the external appearance of the electronic device even if the electronic device is formed in a unibody structure. 
     According to various embodiments of the present disclosure, an electronic device may include: a housing that forms an interior space therein; at least one electronic component that is included within the housing; an opening that penetrates the housing in a first direction and reaches the interior space; and a fluid detecting device that is positioned within the housing, is mounted adjacent to the opening, and detects the contact of a fluid. 
     The fluid detecting device may include: a first member that includes a material or a circuit on a surface thereof, which reacts due to its contact with the fluid; and a second member that encloses a portion of the first member to hinder the fluid from coming into contact with the material or the circuit when the fluid flows in the first direction while allowing the fluid to come into contact with the material or the circuit when the fluid flows in at least one direction, which is different from the first direction. 
     According to various embodiments, the electronic device allows the fluid detecting device to be visually observed from the outside of the housing while the fluid detecting device is provided within the housing. Therefore, the electronic device can be implemented to have an aesthetically pleasing exterior appearance even though the fluid detecting device is installed in the unibody structure. In addition, since it is possible to visually observe whether the electronic device is polluted or damaged through the fluid detecting device from the outside of the electronic device even if the electronic device is not disassembled, the fluid detecting device may be useful for the repair/maintenance of the electronic device. In addition, by setting a foreign matter infiltration route, or the like, using the shape of the second member, or the like, in configuring the fluid detecting device, the fluid detecting device may be used to determine the reason for the pollution or damage.

     DETAILED DESCRIPTION 
     Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements. In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B. 
     The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure. 
     It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them. 
     The expression “configured to” as used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device. 
     In the present disclosure, the terms are used to describe specific embodiments, and are not intended to limit the present disclosure. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. In the description, it should be understood that the terms “include” or “have” indicate existence of a feature, a number, a step, an operation, a structural element, parts, or a combination thereof, and do not previously exclude the existences or probability of addition of one or more another features, numeral, steps, operations, structural elements, parts, or combinations thereof. 
     Unless defined differently, all terms used herein, which include technical terminologies or scientific terminologies, have the same meaning as that understood by a person skilled in the art to which the present disclosure belongs. Such terms as those defined in a generally used dictionary are to be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present specification. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure. 
     In the present disclosure, an electronic device may be a random device, and the electronic device may be called a terminal, a portable terminal, a mobile terminal, a communication terminal, a portable communication terminal, a portable mobile terminal, a display device or the like. 
     For example, the electronic device may be a smartphone, a portable phone, a game player, a TV, a display unit, a heads-up display unit for a vehicle, a notebook computer, a laptop computer, a tablet Personal Computer (PC), a Personal Media Player (PMP), a Personal Digital Assistants (PDA), and the like. The electronic device may be implemented as a portable communication terminal, which has a wireless communication function and is portable. Further, the electronic device may be a flexible device or a flexible display device. 
     The electronic device may communicate with an external electronic device, such as a server or the like, or perform an operation through an interworking with the external electronic device. For example, the electronic device may transmit an image photographed by a camera and/or position information detected by a sensor unit to the server through a network. The network may be a mobile or cellular communication network, a Local Area Network (LAN), a Wireless Local Area Network (WLAN), a Wide Area Network (WAN), Internet, a Small Area Network (SAN) or the like, but is not limited thereto. 
       FIG. 1  is an exploded perspective view illustrating an electronic device  100 , according to one of various embodiments of the present disclosure.  FIG. 2  is a perspective view illustrating a portion of the electronic device  100 , according to one of various embodiments of the present disclosure, in an enlarged scale. 
     Referring to  FIGS. 1 and 2 , according to one of various embodiments of the present disclosure, the electronic device  100  is formed in a unibody structure (e.g., a type formed to have a single housing  101  of which the front side is opened). A display device  102  may be mounted on or within the open front side of the housing  101 . 
     The housing  101  may be provided with a circuit board  111 , on which various circuit devices (e.g., electronic components E, such as an application processor, a communication module, and an internal memory), and various connection devices  113 ,  143 , and  145  that provide means for connecting the electronic device  100  to another electronic device or an additional device. The connection devices  113 ,  143 , and  145  may include, for example, a connector  143  to connect a charger or other electronic devices, a jack  145  to connect an ear phone or a microphone, and a socket in which a storage medium, a Subscriber Identification Module (SIM) card, or the like is mounted. The connection devices  113 ,  143 , and  145  as described above may be mounted on the circuit board  111  or an auxiliary circuit board  141  provided separately from the circuit board  111 . The arrangement of the connection devices  113 ,  143 , and  145  may be properly adjusted in consideration of the positions of the other electronic components E arranged within the housing  101 . The housing  101  may include openings  115 ,  147 , and  149  so as to expose connection routes to the connection devices  113 ,  143 , and  145 . In the following detailed description, the connection devices may be denoted by reference “ 113 ” only. 
     The display device  102  may be configured by stacking display elements to output a screen, and a window member to transmit the screen therethrough while protecting the display elements. According to various embodiments, the display device  102  may include a touch panel to provide a touch screen function so that the display device  102  may also be used as, for example, an input device. The display device  102  may close the front side of the housing  101  so as to complete the exterior of the electronic device  100  so that most of the region of the front side of the housing  101  may be used as a screen display region  121 . The display device  102  may include, around the periphery of the screen display region  121 , a speaker hole  123  to output a sound, a transmission window  127  for various sensors (e.g., a proximity sensor or a illuminance sensor), and a keypad  125  to be operated in a mechanical or touch manner. 
     The housing  101  may form an internal space to accommodate the circuit board  111  or the like, as well as a fluid detecting device  103  to indicate pollution or damage of the electronic device  100  therein. The configuration of the fluid detecting device  103  will be described in more detail with reference to, for example,  FIG. 3 . 
       FIG. 3  is an exploded perspective for describing a fluid detecting device  103  of the electronic device  100 , according to one of various embodiments of the present disclosure.  FIG. 4  is an exploded perspective view illustrating the fluid detecting device  103  of the electronic device  100 , according to one of various embodiments of the present disclosure.  FIG. 5  is a partially cross-sectional view illustrating a configuration of the electronic device  100 , according to one of various embodiments of the present disclosure. 
     In describing the construction of the fluid detecting device  103  illustrated in  FIGS. 3 to 5 , reference will be made to the above-described construction of the electronic device  100 . 
     The fluid detecting device  103  may be positioned within the housing  101  adjacent to any one of the openings  115 ,  147 , and  149  or each of two or more of the openings  115 ,  147 , and  149  to be exposed to the outside. For example, the fluid detecting device  103  may be mounted on the inner wall of the housing  101  or on the inner wall of any of the openings  115 ,  147 , and  149  to be visually identified from the outside of the housing  101 . A mounting recess  117  may be formed on the inner wall of the housing  101  (or the inner wall of the opening  115 ) for mounting the fluid detecting device  103  within the housing  101 . The depth of the mounting recess  117  may be formed to correspond to the thickness of the fluid detecting device  103 . In a specific embodiment of the present disclosure, the fluid detecting device  103  may be positioned adjacent to the connection device  113  (e.g., a socket for a storage medium or the like). The fluid detecting device  103  may be degenerated by foreign matter that flows into the housing  101  from the outside so as to allow a user or a service provider to recognize pollution, damage, or the like inside the electronic device  100 . The foreign matter may flow into the housing  101  not only through the openings corresponding to the above-described connection devices, but also through openings for the input/output of a sound at the time of a voice call (e.g., the above-mentioned speaker hole  123 ), a sound output hole provided separately from the above-mentioned speaker hole  123 , a coupling boundary portion between various outwardly exposed components, or the like. The fluid detecting device  103  may be positioned in consideration of such foreign matter inflow routes. 
     The fluid detecting device  103  may include a first member  131  and a second member  132 . The second member  132  may include a first guide member  133  attached to the housing  101 , and a second guide member  135  attached to the first guide member  133 . 
     The first member  131  may be degenerated by foreign matter that has flowed into the housing  101  from the outside (e.g., a fluid, such as moisture or water). For example, the first member  131  may include a material that reacts due to its contact with the fluid (e.g., a paper, a non-woven cloth, or a fabric that is printed or coated with a water-soluble dye) and may be decolored by the fluid (e.g., moisture or water). According to various embodiments, the first member  131  may include, on its surface, a circuit that reacts due to its contact with a fluid. The circuit, which is included in the first member  131  and reacts due to its contact with the fluid, may be electrically connected with one of the electronic components E that is accommodated within the housing  101  (e.g., an application processor). 
     According to various embodiments, in the case where the first member  131  includes a material that reacts due to its contact with a fluid, the first member  131  may be coated with a water-soluble fixing liquid (e.g., alumina liquid, acryl liquid, or urethane liquid). As a result, the first member  131  may be degenerated (e.g., decolored) when moisture or water infiltrates into the electronic device  100 . The degree by which the first member  131  is degenerated may correspond to the degree by which a malfunction of the electronic device would occur such that minor infiltrations may cause minimal or no degeneration of the first member  131 . 
     The second member  132  may accommodate the first member  131 , and may provide a route that allows the foreign matter (e.g., moisture or water) infiltrating into the house  101 , to reach the space that accommodates the first member  131 , in a predetermined direction. For example, it is possible to limit the route that allows the foreign matter infiltrating into the housing  101  from the outside, to reach the first member  131  within the housing  101 . 
     The first guide member  133  may be manufactured by processing a film, which is formed of a synthetic resin (e.g., a polycarbonate material) and may have a thickness of scores to hundreds of micrometers (μm). The first guide member  133  may have a “C” shape. However, the present disclosure is not necessarily limited thereto, and the shape or the like of the first guide member  133  will be described in more detail with reference to, for example,  FIG. 6 . The first guide member  133  may be arranged to partially enclose the circumference of the first member  131 . For example, the first guide member  133  may provide an accommodation portion  139  that accommodates the first member  131 . The first guide member  133  may be attached such that one surface thereof faces the inner wall of the housing  101  (e.g., the recess  117  of the mounting recess). 
     An adhesive or a double-sided tape  137  may attach the guide member  133  to the mounting recess  117 . According to various embodiments, for the first guide member  133 , a portion of the second member may be formed by the housing  101  itself by processing the inner wall of the housing  101 . For example, a portion of the second member  132  may be formed by processing the inner wall of the housing  101  (e.g., the mounting recess  117 ) to correspond to the shape of the first guide member  133 . 
     The second guide member  135  may be attached to the other surface of the first guide member  133 . For example, the accommodation portion  139  may be closed by the second guide member  135  on the other surface of the first guide member  133 . The first member  131  may be disposed between the inner wall of the housing  101  (e.g., the bottom surface of the mounting recess  117 ) and the second guide member  135  by being attached to the second guide member  135  and accommodated into the accommodation portion  139 . The second guide member  135  may include a single-sided tape. When the second guide member  135  includes a single-sided tape, after the second guide member  135  is attached to the first guide member  133 , the tape may facilitate attaching the first member  131  thereto. Opposite surfaces of the first member  131  may be enclosed by the inner wall of the housing  101  and the second guide member  135 , respectively, and most of the circumference thereof may be enclosed by the first guide member  133 . A portion of the accommodation portion  139  may be communicated with the outside of the first guide member  133  so as to allow the foreign matter, which infiltrates into the housing  101  from the outside, to flow into the accommodation portion  139 . In addition, the second guide member  135  may be made of a transparent material so that the first member  131  may be easily visually identified even at the outside of the housing  101  through the opening  115 . 
     According to the arrangement and shape of the second member  132  as described above, a route, which allows foreign matter (e.g., a fluid, such as moisture or water) to infiltrate into the housing  101  from the outside to the first member  131 , may be limited thereto so that the foreign matter is inhibited from entering areas outside of the route. The fluid detecting device  103  may be arranged adjacent to the upper end of the housing of the electronic device  100 . For example, the connection device  113  for a storage medium or the like is arranged in the upper end portion within the housing  101 , and the fluid detecting device  103  may be arranged on the inner wall of the housing  101  (or the inner wall of the opening  115 ) between the connection device  113  and the outer surface (e.g., the upper end surface) of the housing  101 . Accordingly, the fluid detecting device  103  may be visually exposed to the outside through an opening (e.g., the opening  115  formed in the upper end surface of the housing  101 ) formed to correspond to the connection device  113 . 
     The above-mentioned fluid detecting device  103  (e.g., the second member) may limit the route that allows the foreign matter to infiltrate into the first member  131 . For example, referring to  FIG. 5 , the foreign matter infiltrating from the opening  115  to a position where the first member  131  is positioned, is blocked by the first guide member  133  or the second guide member  135  so that the foreign matter may not or is inhibited from reaching the first member  131 . For example, even if a small amount of water infiltrates through the opening  115  while the user performs a voice call, the water may not reach the first member  131  by being blocked by the first guide member  133  and the second guide member  135 , and the first member  131  may not be degenerated. Whereas, when the amount of water, which infiltrates through the opening  115  or other various routes (e.g., the above-mentioned speaker hole  123  or the like), increases (e.g., by being waterlogged), for example, when water is collected in a space, for example, between the fluid detecting device  103  and the circuit board  111 , the water may infiltrate into the accommodation portion  139 . For example, when the water infiltrates into the electronic device  100  over a predetermined amount, the degeneration of the first member  131  may be caused, and based on this, a user or a service provider may foresee or sense the pollution of the electronic device  100  or the damage caused thereby. 
     The above-described embodiments have exemplified a configuration in which the fluid detecting device  103  is arranged adjacent to a socket for a storage medium or openings  147  and  149 . However, the fluid detecting device  103  may be arranged to correspond to the other types of connection devices described above, such as, for example, the connector  143  and the jack  145 ). In addition, while a specific embodiment of the present disclosure has exemplified a configuration in which one fluid detecting device  103  is disposed within the housing  101 , a plurality of fluid detecting devices may be arranged at different positions such as, for example adjacent to the speaker hole  123  or the like. 
       FIGS. 6 to 10  are views illustrating various configurations of the fluid detecting device  103  of the electronic device, according to one of various embodiments of the present disclosure, respectively. 
     The fluid detecting device  103  may variously set the foreign infiltration routes according to the configuration (e.g., shape) of, for example, the first guide member  133 . In the following description made with reference to  FIGS. 6 to 10 , descriptions will be made with reference to a configuration in which the opening  115  of the housing  101  reaches the interior space of the housing  101  from the upper side of the fluid detecting device  103  through the housing  101  along a first direction as illustrated in  FIGS. 6 to 10 , by way of an example. 
     The fluid detecting device  103  illustrated in  FIGS. 6 and 7  is exemplified to have a configuration that is the same as or similar to the above-mentioned fluid detecting device. In the fluid detecting device  103 , a foreign matter infiltration route may be formed in a direction parallel to and opposite to the opening  115 , for example, in a reverse direction to the first direction. For example, the accommodation portion  139  may communicate with the outside of the first guide member  133  to the lower side of the fluid detecting device  103 . Here, the description, “parallel to the opening  115 ,” may mean that the foreign matter infiltration route is parallel to the direction where the opening  115  and the fluid detecting device  103  are arranged. 
     According to various embodiments, as illustrated in  FIG. 7 , the fluid detecting device  103  may further include an infiltration route  141  that is formed in a direction inclined to the opening  115  (which is shown in  FIG. 5 ). The infiltration route  141  formed in the direction inclined to the opening  115  may extend to be spaced away from the opening  115  in a direction away from the first member  131 . In the fluid detecting device  103 , the foreign matter, which may infiltrate in a direction perpendicular to the opening  115  or toward the first member  131  from the opening  115 , may be blocked. For example, the first guide member  133  may block foreign matter, which may infiltrate in the direction perpendicular to the opening  115  or toward the first member  131  from the opening  115 . In addition, the foreign matter, which infiltrates in the inclined direction from a point adjacent to the opening  115  toward the first member  131 , may also be blocked by the first guide member  133 . 
     The foreign matter infiltration routes of the fluid detecting device  103 , which are illustrated in  FIGS. 6 and 7 , respectively, may be implemented to have different widths. Even if the first members  131  are made of the same dye and in the same size, the amounts of water, which are required for degenerating the first members  131 , respectively, may be different from each other. For example, in the case where the fluid detecting device with a narrower foreign matter infiltration route (e.g., the fluid detecting device illustrated in  FIG. 7 ) is installed in the electronic device  100 , the first member  131  may be degenerated only when a larger amount of foreign matter than that of the foreign matter, which infiltrates into the fluid detecting device illustrated in  FIG. 6 , infiltrates into the inside of the housing  101 . For example, the fluid detecting device  103  illustrated in  FIG. 6  may be decolored even in a case where the electronic device is partially exposed to highly humid weather or rainy weather. In the case where the electronic device is completely submerged under water (waterlogged), the fluid detecting device illustrated in  FIG. 7  may be degenerated in a state where the electronic device. When both the fluid detecting devices  103  illustrated in  FIGS. 6 and 7  are provided in the electronic device  100 , it is possible to determine whether the pollution or damage of the electronic device  100  is caused by simple moisture or water infiltration or whether the pollution or damage of the electronic device  100  is caused by waterlogging. For example, when only the fluid detecting device illustrated in  FIG. 6  was decolored in the electronic device in which both the fluid detecting devices  103  illustrated in  FIGS. 6 and 7  are provided, it can be determined that the pollution was caused by simple moisture or water infiltration. On the other hand, when the fluid detecting device illustrated in  FIG. 7  was also decolored, it can be determined that the electronic device  100 , in which both the fluid detecting devices  103  are provided, was completely submerged under water. 
     Referring to  FIG. 8 , the accommodation portion  139  may communicate with the outside of the first guide member  133  in a direction that is orthogonal to the opening  115  (e.g., a second direction substantially orthogonal to the first direction). For example, the fluid detecting device  103  illustrated in  FIG. 8  may provide a foreign matter infiltration route along a direction perpendicular to the opening  115  may block foreign matter, which infiltrates in a direction parallel to or inclined to the opening  115 . 
     Referring to  FIGS. 9 and 10 , according to various embodiments, the fluid detecting device  103  may include a plurality of first members  131 . 
     A first guide member  133  of the fluid detecting devices  103  may provide a plurality of accommodation portions  139  that are spaced apart from each other. The first members  131  may be arranged in the accommodation portions  139 , respectively, and the accommodation portions  139  may provide foreign matter infiltration routes that are independent from each other. For example, the plurality of accommodation portions  139  and first members  131  may be arranged symmetrical to each other on the first member  101 . Similar to the embodiments described above, the fluid detecting device  103  may limit the routes that allow fluid or other matter, which has infiltrated from the outside, to reach the first members  131 . For example, depending on the directions where the accommodation portions  139  are communicated with the outside of the first guide member  133 , the fluid detecting device  103  may guide the foreign matter infiltration route to a direction that is parallel to or perpendicular to the opening  115 . 
       FIGS. 9 and 10  exemplify a configuration in which the first members  131  or the like are symmetrically arranged. According to various embodiments, the plurality of accommodation portions  139  may have asymmetric shapes in relation to each other on the first guide member  133 . For example, the left accommodation portion may have a foreign matter infiltration route that is formed to be smaller than that of the right accommodation portion. Accordingly, in the case of the accommodation portions  139  having asymmetric shapes in relation to each other, the degree of pollution of the electronic device  100  (e.g., whether the electronic device  100  suffered from moisture or water infiltration or waterlogging) may be determined depending on whether the first members  131  are degenerated. In addition, in the case where the accommodation portions  139  have symmetric shapes, it may be possible to determine from which direction the electronic device  100  suffered from waterlogging and how much the electronic device  100  suffered from the waterlogging when it is observed that any one of the first members  131  is discolored. 
     As described above, when a plurality of first members  131  are arranged in one fluid detecting device  103 , the pollution process, the pollution degree, or the like of the electronic device  100  may be determined according to the positions of the first members  131  or the shapes of the accommodation portions  139  (e.g., the direction communicated to the outside of the first guide member  133 ). For example, when the electronic device including the fluid detecting device  103  illustrated in  FIG. 10  suffers from the moisture or water infiltration from the left side, only the left first member may be decolored. In addition, even if all the first members  131  are degenerated, the first member, which was first subjected to the moisture infiltration or the water infiltration, is more degenerated so that the water infiltration direction, the pollution degree, or the like of the electronic device may be foreseen. 
     In describing various embodiments of the present disclosure, although the routes, which allow foreign matter to infiltrate into the accommodation portion  139 , have been described with reference to a configuration in which the route is formed in the reverse direction to the first direction (e.g., the embodiments illustrated in  FIGS. 6, 7, and 9 ) and a configuration in which the route is formed in a direction substantially perpendicular to the first direction (e.g., the embodiments illustrated in  FIGS. 8 and 10 ), respectively, by way of examples, the present disclosure is not necessarily limited thereto. For example, the routes, which allow the foreign matter to infiltrate into the accommodation portion  139 , may have a configuration in which the route is formed in the reverse direction to the first direction and in which the route is formed in the direction substantially perpendicular to the first direction. 
     Like this, according to the various embodiments of the present disclosure, since the electronic device  100  includes the fluid detecting devices  103  that may be observed from the outside (the outside of the housing  100 ) even if the electronic device  100  is not disassembled, the pollution or damage of the electronic device  100  may be easily identified. In addition, according to various embodiments of the present disclosure, the fluid detecting devices  103  of the electronic device  100  may be arranged inside the previously provided openings  115 ,  147 , and  149  (e.g., openings formed to correspond to connection devices) to be easily visually identified while suppressing the degradation of the external appearance of the electronic device  100 . 
       FIG. 11  is a perspective view illustrating a portion of an electronic device, according to another one of various embodiments of the present disclosure, in an enlarged scale.  FIG. 12  is an exploded perspective view for describing a fluid detecting device  203  of an electronic device, according to another one of various embodiments of the present disclosure. 
     The electronic device according to the present embodiment is different from the preceding embodiments in a configuration in which a fluid detecting device  203  is installed. Thus, it is noted that the components that can be easily understood through the preceding embodiments will be denoted by the same reference numerals or omitted and the detailed descriptions thereof may also be omitted. In addition, although not illustrated in  FIG. 11  or the like, the components and reference numerals thereof of the electronic devices described in the preceding embodiments may be cited in the detailed description of the present embodiment. 
     Referring to  FIGS. 11 and 12 , according to another one of various embodiments of the present disclosure, the fluid detecting device  203  of the electronic device  100  may be installed on a connection device  113 . For example, the second member, to which the first member  131  is attached, may be bonded and fixed to the connection device  113 . The housing  101  may further include a second opening  215  that may expose the fluid detecting device  203  to the outside, i.e., to the exterior of the housing  101 . The second opening  215  may be arranged adjacent to the opening  115  formed to correspond to the connection device  113 . The connection device  113  may further include a fixing member  213  (e.g., a hook) to fix the fluid detecting device  203 . 
     In general, the electronic devices may include separate components that are configured to be attachable to/detachable from the electronic devices through the above-described openings, for example, cover members. Among the cover members, a cover C to normally close the opening  115  may be included. The cover C may be directly engaged with the opening  115 , and the user may separate the cover C from the opening  115  as needed. In addition, components that may be attached to or detached from the electronic devices (e.g., the cover members) may include a tray T that is mounted in the opening  115  to be at least partially inserted into the opening, and further, into, for example, the connection device  113 . The tray T may be mounted in the connection device  113  in a push-pull manner. The tray T as described above may include a recess R formed on one surface thereof. In the recess R, an external storage medium (e.g., a package including an integrated circuit) may be accommodated. 
     The connection device of the tray structure may facilitate the insertion and extraction of the storage medium while minimizing the exposure to the outside. The connection device of the tray structure may be provided with a lever or a link, or a hole to operate the lever or the link for the extraction operation, and the second opening  215  may be used as such a hole. 
     The connection device  113  may be arranged adjacent to the opening  115 , and the housing  101  may further include the second opening  215  that is formed parallel to the opening  115 . As described above, the second opening  215  may be used as a hole for providing the binding means or for operating the lever or the like. The connection device  113  may include, for example, a hook as a fixing member  213  for mounting the fluid detecting device  203 . The fixing member  213  extends at a side of the connection device  113 , and may have a “U” shape in the portion where it is bonded to the fluid detecting device  203 . Meanwhile, in the case where the connection device  113  is manufactured in the tray structure, the fixing member  213  may be used as a lever to extract the storage medium mounted in the connection device  113 . For example, the fixing member  213  may be disposed adjacent to the second opening  215 . The fluid detecting device  203  may be fixed to the connection device  113  through the fixing member  213  to face the second opening  215  or may be positioned in close contact with the inner wall of the housing  101  around the second opening  215 . 
       FIG. 13  is a perspective view illustrating a fluid detecting device  203  of an electronic device, according to another one of various embodiments of the present disclosure. 
     Referring to  FIG. 13 , the fluid detecting device  203  may include a second member and a first member  131  that is attached to the inner surface of the second member (e.g., the inner surface of a mounting portion to be described later). 
     The second member may include a protrusion  231  and a mounting portion  233  formed around the protrusion  231 . The mounting portion  233  may be formed to at least partially enclose the outer peripheral surface of the protrusion  231  with a gap being interposed therebetween. The protrusion  231  may be at least partially enclosed by the fixing member  213 . For example, the gap between the protrusion  231  and the mounting portion  233  may form a binding recess  235  so that a portion of the connection device  113  (e.g., a portion of the fixing member  213 ) may be engaged in the binding recess  235 . The first member  131  may be attached to the inner wall of the binding recess  235  (e.g., the inner surface of the mounting portion  233 ). The second member may be made of a transparent material (e.g., a synthetic resin, such as polycarbonate or acryl). Accordingly, even if the first member  131  is attached to the inner surface of the mounting portion  233 , a user or a service provider may observe whether the first member  131  is decolored from the outside of the fluid detecting device  203 . 
     A structure for installing the fluid detecting device  203  will be described with reference to  FIGS. 14 to 17 . 
       FIG. 14  is a view for describing a mounted state of a fluid detecting device  203  of an electronic device, according to another one of various embodiments of the present disclosure.  FIG. 15  is a view illustrating the fluid detecting device  203  of an electronic device, according to another one of various embodiments of the present disclosure, which is viewed from the outside of the housing  101  of the electronic device.  FIG. 16  is a view for describing a state in which the fluid detecting device  203  of an electronic device, according to another one of various embodiments of the present disclosure, is arranged within the housing  101  of the electronic device.  FIG. 17  is a sectional view taken along line A-A in  FIG. 16   
     As illustrated in  FIGS. 14 to 17 , the fluid detecting device  203  may be mounted on and fixed to the connection device  113  (e.g., the fixing member  213 ). As described above, the fixing member  213  may be used as a lever for extracting a storage medium or the like from the connection device of the tray structure, and may be arranged adjacent to the second opening  215 . For example, the connection device  113  may be arranged adjacent to the opening  115 , and the fixing member  213  may be arranged adjacent to the second opening  215 . The fluid detecting device  203  may be mounted on the fixing member  213  to visually expose the first member  131  through the second opening  215 . However, when a cover member (not illustrated) is mounted on the opening  115 , the opening  115  and the second opening  215  may be closed and the first member  131  may also be concealed. 
     In fixing and mounting the fluid detecting device  203  on the fixing member  213 , the fixing member  213  may be arranged such that it enclosing at least a portion of the protrusion  231 . The mounting portion  233  may be arranged to enclose at least a portion of the fixing member  213 . The fixing member  213  may be configured in a “U” shape, and the binding recess  235  may have corresponding shape to that of the fixing member  213 . In addition, by coupling the fixing member  213  to the binding recess  235 , the movement of the fluid detecting device  203  in relation to the fixing member  213  may be restricted. For example, the movement of the fluid detecting device  203  in a horizontal direction (X) or in a vertical direction (Y) in relation to the fixing member  213  may be restricted. Accordingly, the fluid detecting device  203  may be maintained in the state where the fluid detecting device  203  is aligned with the second opening  215 , and the first member  131  may also be exposed to the outside of the housing  101  through the second opening  215 . 
     The second member may guide or restrict an infiltration route of foreign matter to the first member  131 . For example, the foreign matter infiltrating through the second opening  215  is blocked by the second member so that the foreign matter cannot reach the first member  131 . Referring to  FIG. 14 , foreign matter may infiltrate toward the first member  131  from the left side of the second member in the horizontal direction (X), and the foreign matter infiltrating from the right side is blocked by the second member so that the foreign matter cannot reach the first member  131 . 
     As described above with reference to the embodiments, the route that allows foreign matter to reach the first member  131  described above is not limited to the exemplary embodiments and may be variously changed depending on the configuration (shape) of the second member. For example, in the structure illustrated in  FIG. 16 , it will be appreciated that a route, which allows the foreign matter to infiltrate into the first member  131 , may be formed in the case where foreign matter infiltrates through an opening (e.g., the above-described opening  115 ) formed to correspond to the connection device  113 . However, the route, which allows the foreign matter to infiltrate into the first member  131 , may be blocked by the opening, which is formed to correspond to the connection device  113  depending on the shape of the second member. 
       FIGS. 18 to 21  are views illustrating various configurations of the fluid detecting device  203  of the electronic device, according to another one of various embodiments of the present disclosure. 
     As illustrated in  FIGS. 18 to 21 , the fluid detecting device  203 , for example, the second member may be variously changed. 
     For example, as illustrated in  FIG. 19 , the second member may further include an accommodation recess  235   a  to which the first member  131  is attached. The first member  131  may not protrude above the binding recess  235   a  by being accommodated in the accommodation recess  235   a.  For example, it is possible to prevent the fixing member  213  from being interfered with the first member  131  in the process of mounting the fluid detecting device  203  on the fixing member  213 . 
     Referring to  FIGS. 20 and 21 , the fluid detecting device  203  may further include an optical member arranged to correspond to the first member  131  (e.g., a convex lens  235   b  or a polarizing plate  235   c ). The optical members  235   b  and  235   c  may be arranged integrally on the outer surface of the mounting portion  233  or may be separately assembled to the outer surface of the mounting portion  233 . In a practical electronic device, when the opening (e.g., the second opening  215 ) aligned to the first member  131  is formed to be considerably small, it is possible to more easily identify whether the first member  131  is discolored by providing the above-mentioned optical members  235   b  and  235   c.

For example, although the specific embodiments of the present disclosure have exemplified the configuration of the second member in which the accommodation recess  235   a  or each of the optical members  235   b  and  235   c  is formed, the present disclosure is not limited thereto. Also for example, the second member having the accommodation recess  235   a  formed therein may also include the optical member, such as the convex lens  235   b  or the polarizing plate  235   c.
