         [0093]    At least a portion of the slider  140  may be exposed outward from the holder  110  such that the user can manipulate the slider  140 . The slider  140  may be moved by a user&#39;s manipulation, whereby the extent of opening of the first discharge ports and the second discharge ports may be adjusted. 
         [0094]    The holder  110  includes a first holder member  120  and a second holder member  130 . The scent member installation space  111 , in which the scent member  5  is mounted, may be formed between the first holder member  120  and the second holder member  130 . 
         [0095]    The scent member installation space  111  may be formed in the first holder member  120  or the second holder member  130 . In this example, the scent member installation space  111  may be formed in the second holder member  130 . A slider installation space  113 , in which the slider  140  is mounted, may be formed in the first holder member  120 . 
         [0096]    The discharge ports  124  may be formed in the first holder member  120  or the second holder member  130 . In this implementation, the discharge ports  124  are formed in the first holder member  120 . 
         [0097]    The first holder member  120  includes a first housing  121 , in which the slider installation space  113  is formed. 
         [0098]    The second holder member  130  includes a second housing  131 , in which the scent member installation space  111  is formed. 
         [0099]    The scent member  5  and the slider  140  are arranged opposite to each other. 
         [0100]    The discharge ports  124  and a slit  125  are formed in the first housing  121 . 
         [0101]    The slit  125  extends in a longitudinal direction of the first holder member  120  to guide the movement of the slider  140 . 
         [0102]    The slit  125  may be formed separately from the discharge ports  124 . In this implementation, the slit  125  may be connected to one of the discharge ports  124 , i.e. a discharge port  124   a.    
         [0103]    In this implementation, the discharge port  124   a  connected to the slit  125  is used as a manipulation part installation hole, in which the slider  140  is mounted. The manipulation part installation hole may be formed separately from the discharge port  124   a.    
         [0104]    The discharge port  124   a  is formed so as to be wider than the slit  125 . 
         [0105]    The first holder member  120  and the second holder member  130  may be separably coupled to each other. Furthermore, the first holder member  120  and the second holder member  130  may be connected to each other such that the first holder member  120  and the second holder member  130  can be rotated relative to each other. 
         [0106]    To this end, one selected from between the first holder member  120  and the second holder member  130  may include a pivot  127 , which is used as a rotational shaft about which the other selected from between the first holder member  120  and the second holder member  130  can be rotated, and the other selected from between the first holder member  120  and the second holder member  130  may include a hinge coupling unit  132 , which is rotatably coupled to the pivot  127 . 
         [0107]    The hinge coupling unit  132  may be separably coupled to the pivot  127 . The hinge coupling unit  132  extends so as to correspond to the pivot  127 . 
         [0108]    The hinge coupling unit  132  may be provided with a recess  132   a  (see  FIG. 6 ), through which the pivot  127  is inserted. The hinge coupling unit  132  may be formed from an elastic material (e.g. a synthetic resin) such that the circumference of the recess  132   a  is elastically deformed to some extent when the pivot  127  is inserted into the recess  132   a . The first holder member  120 , the second holder member  130 , and/or the slider  140  may be made of a synthetic resin by injection molding. 
         [0109]    The pivot  127  may be forcibly inserted into the hinge coupling unit  132 . When the pivot  127  is inserted into the hinge coupling unit  132 , the hinge coupling unit  132  is elastically deformed such that the pivot  127  can be inserted into the hinge coupling unit  132 . When the pivot  127  is separated from the hinge coupling unit  132 , the hinge coupling unit  132  may also be elastically deformed. 
         [0110]    The slider  140  includes a plate  141  disposed in the holder  110  such that the plate  141  can move along the holder  110 . A manipulation part  142  may be formed at the plate  141 , the manipulation part  142  being exposed outward from the holder  110 . The manipulation part  142  may be manipulated by a user, and is configured to move along the slit  125 . The opening adjustment ports  144  may be formed in the plate  141 , the opening adjustment ports  144  being configured to overlap the discharge ports  124  so as to expose the scent member  5 . 
         [0111]    The plate  141  may be disposed in the holder  110  to change the area that covers the discharge ports  124  based on the position of the slider  140 . 
         [0112]    The manipulation part  142  is the exposed portion of the slider  140 , and is exposed outward from the holder  110 . The manipulation part  142  constitutes a portion of the slider  140 . In this implementation, the manipulation part  142  protrudes from the plate  141 . In a case where the holder is configured to have a structure in which a portion of the plate  141  is exposed outward, the exposed portion of the plate  141 , which is exposed outward from the holder, may be used as the manipulation part. 
         [0113]    The extent of opening the discharge ports  124  may be adjusted based on the area covered by the plate  141 . One side part of the plate  141  is configured to adjust the extent of opening of the first discharge ports  124 , and the other side part of the plate  141  is configured to adjust the extent of opening of the second discharge ports  124 , on the basis of the manipulation part  142 . 
         [0114]    The slit  125 , which extends in a direction in which the manipulation part  142  moves, may be formed in the holder  110 . In this case, the manipulation part  142  may move along the slit  125 . The slit  125  may extend from one of the discharge ports  124 , i.e. the discharge port  124   a . The discharge port  124   a , which is connected to the slit  125 , is sufficiently large to allow the manipulation part  142  to pass therethrough. 
         [0115]    The manipulation part  142  may be inserted into the discharge port  124   a  from the inside of the discharge port  124   a  such that the manipulation part  142  protrudes outward from the first holder member  120 . 
         [0116]    The slit  125  is formed so as to be narrower than each of the discharge ports  124 . The slit  125  extends in a direction in which the slider  140  moves. The manipulation part  142  is connected to the plate  141  via a connection part that is narrow enough to pass through the slit  125 . 
         [0117]    The amount of scent discharged from the scent diffuser  100  may be set based on the extent of opening of the discharge ports  124 . The extent of opening of the discharge ports  124  corresponds to the position of the manipulation part  142 . 
         [0118]    The plate  141  is configured to move to adjust the area of the discharge ports  124  that is covered. Referring to  FIGS. 10 to 17 , it can be seen that the extent of opening of the discharge ports  124  can be adjusted through several stages based on the position of the manipulation part  142 . 
         [0119]    In the slider  140 , the manipulation part  142  may be located at the middle of the opening adjustment ports  144 . The opening adjustment ports  144  disposed at the upper side of the manipulation part  142  and the opening adjustment ports  144  disposed at the lower side of the manipulation part  142  may be arranged symmetrically. 
         [0120]    The slit  125  may be located in the middle of the holder  110 . The manipulation part  142  is configured to move along the slit  125 , which is located in the middle of the holder  110 . The user may intuitively check the position of the manipulation part  142 . 
         [0121]    A plurality of opening adjustment ports  144  is provided. The opening adjustment ports  144  simultaneously overlap the discharge ports  124  constituting the first line L 1  or the discharge ports  124  constituting the second line L 2 . 
         [0122]    For example, the opening adjustment ports  144  may simultaneously adjust the extent of opening of the discharge ports  124  constituting the first line L 1 . The scent member  5  may be exposed from the discharge ports  124  through the opening adjustment ports  144 . 
         [0123]    In this implementation, one opening adjustment port  144  overlaps one discharge port  124 . 
         [0124]    The opening adjustment ports  144  and the manipulation part  142  are arranged in a line. 
         [0125]    The opening adjustment ports  144  move the same distance as the manipulation part  142 . 
         [0126]    In the above arrangement, it is possible for the user to intuitively check the extent of opening of the discharge ports  124 . The extent of opening of the discharge ports  124  is adjusted based on the position of the manipulation part  142 . 
         [0127]    When the manipulation part  142  is completely aligned with the discharge ports  124 , the discharge ports  124  are completely open. On the other hand, when the manipulation part  142  completely deviates from the discharge ports  124 , the discharge ports  124  are completely closed. 
         [0128]    The slider  140  may be provided with at least one interference protrusion  143 . 
         [0129]    The holder  110  may be provided with one or more positioning protrusions  126   a  to  126   f , which are located in a path along which the interference protrusion  143  moves and which interfere with the interference protrusion  143  when the slider  140  is moved. 
         [0130]    The number of positioning protrusions  126   a  to  126   f  may be greater than the number of interference protrusions  143 . When the user moves the manipulation part  142 , the user may perceive the sensation of the interference protrusions  143  moving over the positioning protrusions  126   a  to  126   f.    
         [0131]    Since the positions of the positioning protrusions  126   a  to  126   f  are set so as to correspond to the extent of opening of the discharge ports  124 , the user may manipulate the slider  140  such that the slider  140  can be appropriately positioned based on a predetermined extent of opening of the discharge ports  124 . 
         [0132]    The holder  110  may be provided with at least one movement restriction protrusion  128   a  and  128   b  for limiting a movable range of the slider  140 . The slider  140  may be disposed between the movement restriction protrusion  128   a  and  128   b.    
         [0133]    The movement of the slider  140  in one direction may be restricted by the first movement restriction protrusion  128   a , and the movement of the slider  140  in the other direction is restricted by the second movement restriction protrusion  128   b.    
         [0134]    The discharge ports  124  may be completely closed (see  FIG. 10 or 11 ) at a position at which the slider  140  cannot move any further due to the first movement restriction protrusion  128   a . The discharge ports  124  may be completely open (see  FIG. 16 or 17 ) at a position at which the slider  140  cannot move any further due to the second movement restriction protrusion  128   b.    
         [0135]    The movement restriction protrusions  128   a  and  128   b  are formed in a direction crossing the movement path of the slider  140 . In this implementation, each of the movement restriction protrusions  128   a  and  128   b  may be formed to have a rib shape. 
         [0136]    Referring to  FIG. 8 , the interference protrusions  143  may be provided at opposite sides of the manipulation part  142 . In the first housing  121 , positioning protrusions  126   a  to  126   f  for restricting the position of one interference protrusion  143  may be disposed at one side of the slit  125  such that the positioning protrusions  126   a  to  126   f  are arranged in a line. 
         [0137]    In the first housing  121 , positioning protrusions  126   a  to  126   f  for restricting the position of the other interference protrusion  143  may be disposed at the other side of the slit  125 , such that the positioning protrusions  126   a  to  126   f  are arranged in a line. The positioning protrusions  126   a  to  126   f  for restricting the position of one interference protrusion  143  and the positioning protrusions  126   a  to  126   f  for restricting the position of the other interference protrusion  143  may be disposed symmetrically. 
         [0138]    Referring to  FIGS. 10 to 17 , the scent diffuser  100  may be configured such that the discharge ports  124  can be adjusted to have four extents of opening, for example, fully open, ⅓ open, ⅔ open, and fully closed. The six positioning protrusions  126   a  to  126   f  may be arranged along the movement path of the interference protrusions  143  in a line. 
         [0139]    Referring to  FIG. 10 or 11 , the first positioning protrusion  126   a  is configured to interfere with the interference protrusion  143  when the slider  140  is moved from the left to the right. After the interference protrusion  143  moves over the first positioning protrusion  126   a , the slider  140  comes into contact with the first positioning protrusion  126   a , with the result that the slider  140  does not move any further. 
         [0140]    Referring to  FIG. 12 or 13 , the second positioning protrusion  126   b  and the third positioning protrusion  126   c  are provided so as to set the position of the slider  140  at which the discharge ports  124  are ⅓ open. 
         [0141]    In a state in which the discharge ports  124  are ⅓ open, the interference protrusion  143  is located between the second positioning protrusion  126   b  and the third positioning protrusion  126   c  (hereinafter, referred to as a ⅓ open position). 
         [0142]    Referring to  FIG. 14 or 15 , the fourth positioning protrusion  126   d  and the fifth positioning protrusion  126   e  are provided so as to correspond to the position of the slider  140  at which the discharge ports  124  are ⅔ open. 
         [0143]    In a state in which the discharge ports  124  are ⅔ open, the interference protrusion  143  is located between the fourth positioning protrusion  126   d  and the fifth positioning protrusion  126   e  (hereinafter, referred to as a ⅔ open position). 
         [0144]    Referring to  FIG. 16 or 17 , when the slider  140  is moved from the position at which the discharge ports  124  are ⅔ open, the interference protrusion  143  moves over the six positioning protrusion  126   f . At this time, the slider  140  comes into contact with the second movement restriction protrusion  128   b , with the result that the slider  140  does not move any further. 
         [0145]    As described above, the positioning protrusions  126   a  to  126   f  may enable the user to recognize the positions of the slider  140  that correspond to the extent of opening of the discharge ports  124  based on the sensation of manipulation during the manipulation of the slider  140 , and may prevent the movement of the slider  140  after the interference protrusions  143  are located at the predetermined positions (e.g. the ⅓ open position and the ⅔ open position). 
         [0146]    According to implementations, the positioning protrusions may be configured differently. For example, a larger number of positioning protrusions may be provided in order to adjust the extent of opening of the discharge ports  124  through a larger number of stages. 
         [0147]    In another implementation, one selected from between the slider  140  and the holder  110  may include an interference protrusion, and the other selected from between the slider  140  and the holder  110  may include positioning insertion parts, into which the interference protrusion is inserted when the slider  140  is located at predetermined positions. In this case, the positioning insertion parts may be provided at positions corresponding to the extent of opening of the discharge ports  124  and the interference protrusion may be inserted into the positioning insertion parts during the movement of the slider  140 . 
         [0148]    It will be apparent that, although implementations have been described above with reference to the accompanying drawings, the disclosure is not limited to the above-described implementations, and therefore various modifications and variations can be made by those skilled in the art without departing from the scope of the appended claims. Thus, modifications and variations should not be understood independently of the technical spirit or prospect of the disclosure. The above implementations are therefore to be construed in all aspects as illustrative and not restrictive.
