     DESCRIPTION OF EMBODIMENTS 
     Embodiments of the disclosure will be described hereinafter with reference to the accompanying drawings. Note that, in the drawings, the same or equivalent components are denoted by the same reference signs and description thereof will not be repeated. 
     Before describing a discharge device  1  of the disclosure, an electronic apparatus  5  including the discharge device  1  of the disclosure will be described.  FIG.  1    is a perspective view illustrating the electronic apparatus  5  including the discharge device  1  according to an embodiment of the disclosure. 
     The electronic apparatus  5  illustrated in  FIG.  1    includes a blower function and a function of generating a discharge product. In addition to the functions described above, the electronic apparatus  5  may also include a function of changing the physical property of air. The blower function is a function of intaking air around the electronic apparatus  5  into the electronic apparatus  5 , and sending out the in-taken air to the outside of the electronic apparatus  5 . The function of generating a discharge product includes, for example, a function of suppressing the action of bacteria by generating ions or free radicals. The function of changing the physical property of air includes, for example, a function of removing particles in the air. Specifically, the electronic apparatus  5  having the blower function and the function of generating a discharge product into the air is a discharge product generator such as an ion generator or an ozone generator. As a discharge product generator with the function of removing particles contained in the air, the electronic apparatus  5  is an air purifier with a discharge product generating function. The electronic apparatus  5  may include, in addition to an air purifier with a discharge product generating function, a humidifying air purifier with a discharge product generating function, and a humidifying/dehumidifying air purifier with a discharge product generating function. 
     The electronic apparatus  5  includes a main body  51 , a holder  3 , and the discharge device  1 . The discharge device  1  is attached to the holder  3 , and the holder  3  is disposed inside the main body  51 , which has a box shape. 
     Electrical components (not illustrated) for operating the electronic apparatus  5  are housed in the main body  51 . A voltage is applied to the electrical components via a power supply cable (not illustrated) provided outside the main body  51 , and a feeder connector (not illustrated) provided inside the main body  51 . 
     An inlet port  51 A for sucking air present outside the main body  51  is provided in a side surface of the main body  51 . The air taken into the main body  51  from the inlet port  51 A passes through a ventilation passage (not illustrated) provided inside the main body  51 , and is sent out to the outside of the main body  51  from an outlet port  51 B formed in the top surface of the main body  51 . 
     Further, a holder insertion port  51 C that allows the inside and the outside of the main body  51  to communicate is formed in a side surface of the main body  51 . A space inside the main body  51  communicating with the holder insertion port  51 C communicates with the ventilation passage mentioned above. A feeder connector is disposed in this space. 
     A voltage is applied to the discharge device  1  through the feeder connector, so that a discharge product is generated. Examples of the discharge product generated by the discharge device  1  include ions or free radicals. Examples of the ions include a positive ion (for example, H + (H 2 O) m , where m is any integer), a negative ion (for example, O 2− (H 2 O) n , where n is any integer), or a combination of these ions. Examples of the free radicals include a hydroxyl radical (—OH), a hydrogen radical (—H), an oxygen radical (—O), a hydroperoxyl radical (—HO 2 ), hydrogen peroxide (H 2 O 2 ), and ozone (O 3 ). The discharge product has, for example, an effect of suppressing the action of bacteria and suppressing harmful effects of the bacteria on the human body. 
     The discharge device  1  is housed in and held by the holder  3 , thereby being attached to the holder  3 . The discharge device  1  attached to the holder  3  is inserted into the main body  51  through the holder insertion port  51 C. The discharge device  1  inserted into the main body  51  is connected to the feeder connector, and is arranged such that part of the discharge device  1  is exposed on the ventilation passage. The holder  3 , in which the discharge device  1  is arranged as described above, is held in the main body  51 . A voltage is applied to the discharge device  1  connected to the feeder connector. By arranging the discharge device  1  on the ventilation passage, the discharge product is dispersed into the air passing through the ventilation passage. As a result, the discharge product is sent out to the outside of the main body  51  and suppresses the action of bacteria present outside the main body  51 . 
     Referring to  FIG.  2   , the holder  3  to which the discharge device  1  of the disclosure is to be attached will be described below.  FIG.  2    is a cross-sectional view of the holder  3  to which the discharge device  1  according to the embodiment of the disclosure is attached. 
     As illustrated in  FIG.  2   , the holder  3  includes a holder base  31 , a housing portion  32 , a first securing portion  33 , a second securing portion  34 , and a holder handle  35 . Hereinafter, in the description of the holder  3 , the directions illustrated in  FIG.  2    are defined as up-down and left-right directions for convenience. That is, the longitudinal direction of the holder  3  is defined as the left-right direction. The direction orthogonal to the left-right direction is defined as the up-down direction. 
     The holder base  31  is a portion for setting a position of the housing portion  32 , in which the discharge device  1  is housed, with respect to the main body  51 . The housing portion  32  has a box shape. The housing portion  32  is provided at a right end portion of the holder base  31 . By appropriately setting the length of the holder base  31  in the left-right direction, the discharge device  1  housed in the housing portion  32  is partially disposed in the ventilation passage, and the discharge device  1  is connected with the feeder connector. 
     A discharge device housing port  32 P open in the up-down direction is formed in the upper portion of the housing portion  32 . The discharge device housing port  32 P allows the inside and the outside of the housing portion  32  to communicate with each other. The discharge device  1  passes through the discharge device housing port  32 P to move in or out of the housing portion  32 . 
     A bottom surface  32 B is provided inside the housing portion  32 . The interior of the housing portion  32  has a step structure in which a step  32 A is provided. The step  32 A is provided such that the lower side of the housing portion  32  provided with the step  32 A has a small dimension in the left-right direction of a space constituting the housing portion  32  compared to the upper side over the step  32 A. The step  32 A is used for securing and holding the discharge device  1  housed in the housing portion  32 . 
     A connector insertion port  32 E open in the left-right direction is formed in the right end portion of the housing portion  32 . The connector insertion port  32 E allows the inside and the outside of the housing portion  32  to communicate. The connector insertion port  32 E is an opening for guiding the feeder connector with respect to the discharge device  1  housed in the housing portion  32 . 
     The housing portion  32  having the above-described shape includes corners  32 C and  32 F at an edge in contact with the discharge device housing port  32 P and an edge of the step  32 A, respectively. The corners  32 C and  32 F each have a shape subject to chamfering, which is commonly performed in machining. In a case where the discharge device  1  includes similar corners (not illustrated), when the discharge device  1  moves in or out of the housing portion  32 , the corners of the discharge device  1  may catch on the corners  32 C and  32 F of the housing portion  32 . In a case where the corners of the discharge device  1  catch on the corners  32 C and  32 F of the housing portion  32 , the discharge device  1  may be prevented from moving in or out of the housing portion  32  by the corners  32 C and  32 F. 
     The first securing portion  33  protrudes in the left direction from the right upper end portion of the housing portion  32 . The first securing portion  33  catches on the discharge device  1  housed in the housing portion  32  to restrict the discharge device  1  from moving outward beyond the first securing portion  33 , whereby the discharge device  1  is secured in the housing portion  32 . 
     The second securing portion  34  is disposed on a path when the discharge device  1  is moved in or out of the housing portion  32 . The second securing portion  34  is provided to cover, from the outside of the housing portion  32 , a section from the vicinity of the left upper end portion of the housing portion  32  to a portion of the discharge device housing port  32 P. The second securing portion  34  catches on the discharge device  1  housed in the housing portion  32  to restrict the discharge device  1  from rotational movement about the first securing portion  33 , whereby the discharge device  1  is secured in the housing portion  32 . When the discharge device  1  is secured by the second securing portion  34  and the first securing portion  33 , the discharge device  1  is held in the housing portion  32 . 
     The holder handle  35  is connected to the left end portion of the holder base  31 . The holder handle  35  is a portion that allows a user, who is an operator of the electronic apparatus  5  illustrated in  FIG.  1   , to hold the holder  3 . When holding the holder handle  35 , the user can insert the housing portion  32  of the holder  3  into the holder insertion port  51 C illustrated in  FIG.  1    and perform an operation of arranging the housing portion  32  inside the main body  51 . 
     The discharge device  1  according to the embodiment of the disclosure will be described with reference to  FIG.  2    to  FIG.  4   .  FIG.  3    is a perspective view illustrating the discharge device  1  according to the embodiment of the disclosure.  FIG.  4    is a cross-sectional view of the discharge device  1  according to the embodiment of the disclosure. 
     First, the external appearance of the discharge device  1  will be described with reference to  FIGS.  2  and  3   . As illustrated in  FIGS.  2  and  3   , the discharge device  1  includes a housed section  11 , a discharge electrode  14 , and a protector  15 . 
     The housed section  11  is housed in the housing portion  32  such that the discharge electrode  14  is exposed to the outside of the housing portion  32 , and is attached to the housing portion  32  by being held by the housing portion  32 . The housed section  11  holds the discharge electrode  14  configured to generate a discharge product, and electrical circuit components (not illustrated) configured to operate the discharge electrode  14 . The housed section  11  has a box shape. The discharge electrode  14  is provided outside the housed section  11 , and the electrical circuit components are housed therein. 
     The housed section  11  includes a first housed section  12  and a second housed section  13 . The first housed section  12  holds the discharge electrode  14 . The first housed section  12  is held by the step  32 A of the housing portion  32  when housed in the housing portion  32 . The second housed section  13  is provided overlapping the first housed section  12 . The length of the first housed section  12  in the longitudinal direction is greater than the length of the second housed section  13 . The length of the second housed section  13  in the longitudinal direction is preferably smaller than the length, in the longitudinal direction, of a space on the bottom surface  32 B side of the housing portion  32  where the step  32 A is provided by a predetermined length. With this configuration, when the second housed section  13  moves in or out of the housing portion  32 , a space is created between the second housed section  13  and the housing portion  32  in the longitudinal direction of the housing portion  32 . As a result, the second housed section  13  moves in or out of the housing portion  32  while avoiding the step  32 A in the housing portion  32 . 
     The center of the second housed section  13  in the longitudinal direction is preferably closer to one end portion side of the first housed section  12  in the longitudinal direction relative to the center of the first housed section  12  in the longitudinal direction. Further, when the housed section  11  is housed in the housing portion  32 , the second housed section  13  is arranged at a position separate from the step  32 A of the housing portion  32  in the longitudinal direction of the housed section  11 . With this configuration, when the housed section  11  moves in or out of the housing portion  32 , a space is created between the second housed section  13  and the housing portion  32  in the longitudinal direction of the housing portion  32 . As a result, the housed section  11  moves in or out of the housing portion  32  while avoiding the step  32 A of the housing portion  32 . 
     The second housed section  13  is preferably arranged between both end portions of the first housed section  12  in the longitudinal direction, in the longitudinal direction of the first housed section  12 . With this configuration, when the housed section  11  rotates about any position of the first housed section  12  and moves in or out of the housing portion  32 , a space is created between the second housed section  13  and the housing portion  32 . As a result, the housed section  11  moves in or out of the housing portion  32  while avoiding the step  32 A of the housing portion  32  and a surface inside the housing portion  32 . 
     With the first housed section  12  and the second housed section  13  having the above shapes, when the housed section  11  in a tilted orientation with respect to the housing portion  32  is moved in or out of the housing portion  32  while being rotated, the second housed section  13  is housed while avoiding the step  32 A of the housing portion  32 . Thus, the housed section  11  is housed without catching on the step  32 A of the housing portion  32 , that is, easily housed. 
     The first housed section  12  includes a bottom wall  120  and two side walls  121  and  122  opposing each other in the longitudinal direction of the bottom wall  120 . At least one of the two side walls  121  and  122  is connected with the bottom wall  120  via a curved surface  12 A or  12 B. When the first housed section  12  has the above shape and when the corner  32 C of the housing portion  32  comes into contact with the curved surface  12 A or  12 B of the first housed section  12  when the housed section  11  moves in or out of the housing portion  32 , the curved surface  12 A or  12 B of the first housed section  12  guides the corner  32 C of the housing portion  32 . As a result, the first housed section  12  moves in or out of the housing portion  32  without catching on the corner  32 C of the housing portion  32 . 
     Similar to the first housed section  12 , the second housed section  13  includes a bottom wall  130  and two side walls  131  and  132  opposing each other in the longitudinal direction of the bottom wall  130 . When the second housed section  13  is housed in the housing portion  32 , the side wall  131  at one side and the step  32 A of the housing portion  32  oppose each other. In the second housed section  13 , the bottom wall  130  is connected with the side wall  131  at the one side via a curved surface  13 A. 
     In the second housed section  13 , the bottom wall  130  is preferably connected with the side wall  132  at the other side via a curved surface  13 B. 
     The first housed section  12  is provided with a catch portion  12 C formed in a recessed shape for catching the first securing portion  33 . The catch portion  12 C is preferably arranged at a location on a side opposite to the second housed section  13  in the first housed section  12 . With this catch portion  12 C, the housed section  11  may move in or out of the housing portion  32  while the first securing portion  33  is caught on the catch portion  12 C. In this case, the housed section  11  moves in or out of the housing portion  32  by rotating about a contact portion between the catch portion  12 C and the first securing portion  33  toward the bottom surface  32 B of the housing portion  32 . Thus, in a case where the discharge device  1  has to be repeatedly moved in and out of the housing portion  32 , the housed section  11  moves in or out of the housing portion  32  by always passing through the same path. After the housed section  11  is housed in the housing portion  32 , the discharge device  1  is restricted from moving in a direction toward the first securing portion  33  by maintaining a state in which the first securing portion  33  is caught on the catch portion  12 C, whereby the housed section  11  is secured in the housing portion  32 . 
     The discharge electrode  14  is an electrode configured to generate a discharge product, as described above. The discharge electrode  14  is formed of a conductive material such as a metal, carbon fiber, conductive fiber, and conductive resin. The discharge electrode  14  of the present embodiment includes a plurality of linear conductors bundled together to form a brush shape. Note that the shape of the discharge electrode  14  is not limited to a brush shape, and may be any shape such as a rod shape, a needle shape, a linear shape, a fibrous shape, or a plane shape. In the present embodiment, the discharge electrode  14  protrudes from a surface on the side opposite to the surface where the first housed section  12  and the second housed section  13  overlap each other. 
     A plurality of discharge electrodes  14  are preferably disposed along the longitudinal direction of the housed section  11 . When the discharge electrodes  14  are disposed in this manner, it is possible to generate discharge products in amounts corresponding to the number of disposed discharge electrodes  14 , and disperse the generated discharge products into the ventilation passage. In the present embodiment, two discharge electrodes  14  are disposed in the first housed section  12  along the longitudinal direction of the first housed section  12 . 
     The protector  15  surrounds the discharge electrode  14  in a state of maintaining a space around the discharge electrode  14  to protect the discharge electrode  14 . The protector  15  is provided on a surface of the first housed section  12 , from which the discharge electrode  14  protrudes, being spaced from one end portion of the housed section  11  in the longitudinal direction. When the protector  15  has the configuration described above, the second securing portion  34  can be disposed to catch on a portion of the first housed section  12  between an end portion of the first housed section  12  and the protector  15 . The second securing portion  34  caught on the first housed section  12  restricts the rotational movement of the first housed section  12  about the contact portion between the first securing portion  33  and the catch portion  12 C. As a result, the first housed section  12  is secured in the housing portion  32 . Hereinafter, a portion of the first housed section  12  between the end portion of the first housed section  12  and the protector  15  is referred to as a secured portion  12 D. 
     Next, the interior of the discharge device  1  will be described with reference to  FIG.  4   . As illustrated in  FIG.  4   , the discharge device  1  includes a connection portion  21 , a control substrate  22 , a step-up transformer  23 , a capacitor  24 , and a high voltage substrate  25 . 
     The connection portion  21  connects the electrical circuit components including the discharge electrodes  14  to an external power supply via a feeder connector provided inside the main body  51 . The connection portion  21  is connected to the electrical circuit components housed inside the housed section  11 , and part of the connection portion  21  is exposed to the outside of the housed section  11 . The part of the connection portion  21  exposed to the outside of the housed section  11  is connected to the feeder connector. The connection portion  21  is provided at a position in parallel to the catch portion  12 C in the housed section  11 . The connection portion  21  is provided between the curved surface  12 B, connecting the bottom wall  120  and the side wall  122  of the first housed section  12 , and the catch portion  12 C in the first housed section  12 . With the connection portion  21  having the above arrangement, when the housed section  11  rotates and moves in or out of the housing portion  32  while the catch portion  12 C is caught on the first securing portion  33 , the connection portion  21  moves without catching on the bottom surface  32 B or the corners  32 C and  32 F of the housing portion  32 . Thus, the housed section  11  can move in or out of the housing portion  32  with ease. 
     The control substrate  22  has a wide shape and is housed in the first housed section  12 . The control substrate  22  is connected to the connection portion  21 . A voltage is applied to the control substrate  22  from the feeder connector via the connection portion  21 . The step-up transformer  23 , the capacitor  24 , and the electrical components (not illustrated) are mounted on the control substrate  22 . The control substrate  22  is connected to the high voltage substrate  25 . 
     The step-up transformer  23  is a component that boosts a voltage, and has a large depth dimension and large height dimension. The second housed section  13  preferably houses the step-up transformer  23 . With this configuration, the second housed section  13  needs to have a height sufficient for housing the step-up transformer  23 , but the length of the second housed section  13  in the longitudinal direction may be made smaller than the length of the first housed section  12 , as described above. Thus, as described above, the housed section  11  can move in or out of the housing portion  32  without catching on the step  32 A of the housing portion  32 . In the present embodiment, two step-up transformers  23  having differing amplification factors, shapes, and the like are housed in the second housed section  13 . The two step-up transformers  23  are mounted on the control substrate  22  and the high voltage substrate  25 , respectively. The step-up transformer  23  corresponds to an example of a “high voltage generation component” of the disclosure. 
     The capacitor  24  has a function of temporarily storing voltage from the step-up transformer  23 . The capacitor  24  is also a component having a large depth dimension and large height dimension, similar to the step-up transformer  23 . The second housed section  13  preferably houses the capacitor  24 . With this configuration, the length of the second housed section  13  in the longitudinal direction may be made smaller than the length of the first housed section  12 , as described above. Thus, as described above, the housed section  11  can move in or out of the housing portion  32  without catching on the step  32 A of the housing portion  32 . The capacitor  24  corresponds to an example of the “high voltage generation component” of the disclosure. 
     The high voltage substrate  25  plays a role of supplying a desired high voltage obtained by the step-up transformer  23 , the capacitor  24 , and the various electrical components (not illustrated) to the discharge electrode  14 . The high voltage substrate  25  has a wide shape and is housed in the first housed section  12 . 
     Attachment of the discharge device  1  according to the embodiment of the disclosure to the holder  3  will be described with reference to  FIG.  5 A  to  FIG.  5 C .  FIG.  5 A  is a diagram illustrating a preliminary stage of the attachment of the discharge device  1  according to the embodiment of the disclosure to the holder  3 .  FIG.  5 B  is a diagram illustrating a mid-stage of the attachment of the discharge device  1  according to the embodiment of the disclosure to the holder  3 .  FIG.  5 C  is a diagram illustrating a final stage of the attachment of the discharge device  1  according to the embodiment of the disclosure to the holder  3 . 
     The discharge device  1  illustrated in  FIG.  5 A  is housed in the housing portion  32  of the holder  3 , and is then attached to the holder  3  by being secured in the housing portion  32 . In order to make the discharge device  1  be housed in the housing portion  32 , the discharge device  1  is rotated such that the bottom wall  130  of the second housed section  13  faces the bottom surface  32 B of the housing portion  32  while the catch portion  12 C is caught on the first securing portion  33 . 
     When the rotation of the discharge device  1  is advanced, the curved surface  13 B of the second housed section  13  opposes the bottom surface  32 B of the housing portion  32 . The shape of the curved surface  13 B serves to avoid the bottom surface  32 B of the housing portion  32 . Even when the curved surface  13 B comes into contact with the bottom surface  32 B of the housing portion  32 , the curved surface  13 B does not catch on the bottom surface  32 B of the housing portion  32  due to its shape. This makes it possible for the housed section  11  to move in or out of the housing portion  32  with ease. 
     The curved surface  13 A opposes the step  32 A provided inside the housing portion  32 . The shape of the curved surface  13 A serves to avoid the corner  32 F of the step  32 A, or avoid the step  32 A itself. Thus, the housed section  11  moves without catching on the step  32 A of the housing portion  32 . 
     As illustrated in  FIG.  5 B , when the rotation of the discharge device  1  is further advanced, the curved surface  12 A of the first housed section  12  opposes the corner  32 C of the housing portion  32 , which is in contact with the discharge device housing port  32 P. The curved surface  12 A moves without coming into contact with the corner  32 C of the housing portion  32  due to its shape. Even when the curved surface  12 A of the first housed section  12  comes into contact with the corner  32 C of the housing portion  32 , the curved surface  12 A of the first housed section  12  guides the corner  32 C of the housing portion  32 , and thus the first housed section  12  moves without catching on the corner  32 C of the housing portion  32 . 
     When the rotation of the discharge device  1  is further advanced, the discharge device  1  is housed in the housing portion  32 . As described above, the discharge device  1  moves without catching on the corner  32 C of the housing portion  32  in the process of being attached to the housing portion  32 . That is, the discharge device  1  is easily housed in the holder  3 . 
     As illustrated in  FIG.  5 C , the discharge device  1  housed in the housing portion  32  is restricted from moving in a direction beyond the first securing portion  33  by the first securing portion  33 , and only movement in a rotational direction about the first securing portion  33  is allowed. The movement of the discharge device  1  in the rotational direction is restricted by a simple operation of causing the second securing portion  34  to catch on the secured portion  12 D of the first housed section  12 . That is, the discharge device  1  is easily secured by the second securing portion  34 . 
     As described above, the discharge device  1  of the embodiment of the disclosure can be easily housed in the holder  3 , and can also be easily secured in the holder  3 . That is, the discharge device  1  of the embodiment of the disclosure can be easily attached to the holder  3 .
