  The blower fan 3 generates an air flow that flows through the air passage by blowing out air sucked from the opening 3a from the opening 3b. The opening 3 a is provided on a surface perpendicular to the thickness direction (Z direction) of the blower fan 3. The opening 3b is provided on a surface facing the air outlet 40 of the blower fan 3, and discharges air into a space between the substrate 11 and the inner surface of the upper case 1a. The blower fan 3 is disposed between the surface 11a of the substrate 11 and the surface facing the surface 11a of the case 1 in the Z direction.

  The blower fan 3 includes, for example, a centrifugal fan or a propeller fan. The blower fan 3 operates using power from an external power source connected to the battery 7 or the external terminal 9. By the operation of the blower fan 3, external air is introduced into the case 1 from the suction port 30, passes through the air passage, and is then discharged to the outside through the air outlet 40. The blower fan 3 has a larger air volume as the supplied power is larger.

The ion generator 100 may be configured to be able to communicate with an external device via the external terminal 9.

  FIG. 3 is a perspective view showing details of the ion generating element 20 shown in FIG. Referring to FIGS. 2 and 3, ion generation element 20 includes a substrate 11, an ion generation control unit 10 and an ion generation unit 15 disposed on surface 11 a of substrate 11. A part of the ion generating element 20 is covered with an insulating case described later.

  The ion generation control unit 10 is for controlling discharge in the ion generation unit 15 and includes, for example, a pulse generation circuit, a capacitor, an FET (Field Effect Transistor), and the like. The ion generation control unit 10 is connected between the battery 7 and the ion generation unit 15. The ion generation control unit 10 boosts the voltage of the battery 7 to 10 to 20 V and outputs it to the ion generation unit 15. Further, the ion generation control unit 10 generates a pulse signal for controlling discharge of the ion generation unit 15 and outputs the pulse signal to the ion generation unit 15.

  The ion generator 15 includes a high voltage generator 6, a positive rectifier 5a, a negative rectifier 5b, a positive ion discharge unit 4a, and a negative ion discharge unit 4b.

  The high voltage generation unit 6 generates a positive and negative high voltage of 2 to 10 kV based on the signal input from the ion generation control unit 10. The high voltage generator 6 includes a transformer, for example. The high voltage generator 6 has, for example, a rectangular parallelepiped shape. The high voltage generator 6 is disposed so as to protrude from the surface 11 a of the substrate 11. The high voltage generator 6 is arranged so that the longitudinal direction of the high voltage generator 6 is parallel to the direction in which the air from the blower fan 3 (FIG. 2) flows. The high voltage generation unit 6 is disposed at the approximate center between the positive ion discharge unit 4a and the negative ion discharge unit 4b. By disposing the high voltage generator 6 in this way, it is possible to make it difficult to block the air flow. Therefore, an air flow can be effectively generated by the blower fan 3.

  The positive rectifying element 5a is connected between the high voltage generator 6 and the positive ion discharge unit 4a, and only the positive high voltage among the positive and negative high voltages generated by the high voltage generator 6 is a positive ion discharge unit. Pass to 4a. The negative side rectifying element 5b is connected between the high voltage generator 6 and the negative ion discharge unit 4b, and only the negative high voltage among the positive and negative high voltages generated by the high voltage generator 6 is a negative ion discharge unit. Pass to 4b. The positive rectifying element 5a and the negative rectifying element 5b are configured to include, for example, a diode. The positive side rectifying element 5a and the negative side rectifying element 5b have, for example, a cylindrical shape and are configured to be energized in the longitudinal direction thereof. The positive rectifying element 5a and the negative rectifying element 5b are arranged so that the energization direction is parallel to the Y direction. The positive side rectifying element 5 a and the negative side rectifying element 5 b are arranged in a state of being embedded in the thickness direction of the substrate 11 from the surface 11 a of the substrate 11.

  The positive ion discharge part 4a and the negative ion discharge part 4b are parts for generating ions by discharge, and have a needle shape with a sharp tip. The positive ion discharge part 4a and the negative ion discharge part 4b are metals having high heat resistance and high corrosion resistance, and are made of, for example, Inconel. One end (tip) of the needle shape of the positive ion discharge part 4a is exposed to the air, and the other end of the positive ion discharge part 4a is connected to the positive side rectifying element 5a. One end (tip) of the needle shape of the negative ion discharge part 4b is exposed to the air, and the other end of the negative ion discharge part 4b is connected to the negative rectifying element 5b. The negative ion discharge part 4b is provided away from the positive ion discharge part 4a in the Y direction.

The principle that ions are generated in the positive ion discharge part 4a and the negative ion discharge part 4b will be described. The positive ion discharge unit 4a is supplied with a DC pulse voltage having a positive voltage. The negative ion discharge unit 4b is supplied with a DC pulse voltage having a negative voltage. The corona discharge generated between the positive ion discharge part 4a and a ground electrode (not shown) positively ionizes the air near the positive ion discharge part 4a. Positive ions generated by ionization combine with moisture in the air to form cluster ions having a positive charge mainly including H ⁺ (H ₂ O) m (m is an arbitrary natural number). To do. Corona discharge generated between the negative ion discharge portion 4b and a ground electrode (not shown) causes the air near the negative ion discharge portion 4b to be negatively ionized. Negative ions generated by ionization combine with moisture in the air, and are negatively charged clusters composed mainly of O ₂ ⁻ (H ₂ O) n (n is zero or any natural number). Ions are formed. Note that the amount (concentration) of ions generated is adjusted by the voltage applied to the positive ion discharge part 4a and the negative ion discharge part 4b and the pulse period. The discharge unit may be configured to generate only negative ions.

  The board | substrate 11 is provided between the ventilation fan 3 (FIG. 2) and the blower outlet 40 (FIG. 2), and an air path is formed along the surface 11a of the board | substrate 11. FIG. By providing the ion generation control unit 10 and the ion generation unit 15 on one substrate, the number of substrates can be reduced and the cost can be reduced. A configuration in which the ion generation unit 15 is provided on the substrate 11 and the ion generation control unit 10 is provided on another substrate may be employed. The substrate 11 is preferably provided with at least a positive ion discharge part 4a and a negative ion discharge part 4b. The substrate 11 is more preferably provided with an ion generator 15. Thus, by providing a component to which a high voltage is applied on the substrate 11, it is possible to prevent an increase in power consumption due to unintended discharge and damage to surrounding objects.

  An insulating case 90 that covers a part of the ion generating element 20 will be described with reference to FIGS. FIG. 4 is a perspective view of an example of the insulating case 90 that covers a part of the ion generating element. FIG. 5 is a perspective view of the ion generating element to which the insulating case 90 is attached. FIG. 6 is a perspective view of the ion generating element to which the insulating case 90 is attached as viewed from the back side.

  As shown in FIG. 5, the insulating case 90 is provided so as to cover a portion to which the high voltage of the ion generating element 20 is applied, particularly the ion generating portion 15. The insulating case 90 is formed with notches 91a and 91b, a central portion 92, side wall portions 93a and 93b, flat plate portions 94a and 94b, and a side peripheral portion 95. The insulating case 90 is formed using a material having high insulation strength such as epoxy.

  The notches 91 a and 91 b are formed so that the tips of the positive ion discharge part 4 a and the negative ion discharge part 4 b are exposed to the outside of the insulating case 90. The central portion 92 is formed so as to cover the high voltage generating portion 6. The side wall portions 93a and 93b form walls in the Z direction on both sides of the central portion 92 in the Y direction. The flat plate portion 94 a is formed along the substrate 11 between the side wall portion 93 a and the central portion 92. The flat plate portion 94 b is formed along the substrate 11 between the side wall portion 93 b and the central portion 92. The side peripheral portion 95 forms a wall in the Z direction at the peripheral portion of the insulating case 90.

  After the ion generating element 20 is attached as shown in FIG. 6, the space surrounded by the side peripheral portion 95 of the insulating case 90 is filled with a material having high insulation strength. In this manner, the portion excluding the tip of the positive ion discharge part 4a and the negative ion discharge part 4b from the ion generation part 15 is covered with the material having high insulation strength. By providing the insulating case 90 in this way, it is possible to prevent unintended discharge in a portion to which a high voltage is applied.

  Further, the insulating case 90 has a function of rectifying the air flowing along the substrate 11. Specifically, the air blown out from the opening 3b of the blower fan 3 is caused by the insulating case 90 to flow between the first air flow (arrow AR1 in FIG. 5) between the central portion 92 and the side wall portion 93a, the central portion 92, and It is divided into a second air flow (arrow AR2 in FIG. 5) flowing between the side wall portions 93b. The first air flow conveys positive ions generated in the positive ion discharge part 4a to the outside through the air outlet 40. The second air flow conveys negative ions generated in the negative ion discharge part 4b to the outside through the air outlet 40.

  7 is a cross-sectional view taken along line AA in FIG. The flow of air in the ion generator 100 will be described with reference to FIG.

  When the ion generator 100 is activated by the operation of the switch 8 by the user, the blower fan 3 is activated. External air is sucked into the case 1 from the suction port 30 by the operation of the blower fan 3. The air sucked into the case 1 passes between the blower fan 3 and the battery 7 and is introduced into the blower fan 3 (arrow B). The air introduced into the blower fan 3 is discharged from the surface facing the blower outlet 40 of the blower fan 3 into the space between the surface 11a of the substrate 11 and the surface 1f of the upper case 1a (arrow C). The air discharged from the blower fan 3 flows along the surface 11 a of the substrate 11 and is divided into a first air flow and a second air flow by the high voltage generator 6. Thus, an air passage is formed between the surface 11 a of the substrate 11 and the surface 1 f facing the surface 11 a of the case 1. The first air flow conveys positive ions generated in the positive ion discharge part 4a to the outside through the air outlet 40. The second air flow conveys negative ions generated in the negative ion discharge part 4b to the outside through the air outlet 40.

  FIG. 8 is a diagram illustrating an example of a usage state of the ion generator illustrated in FIG. 1. Referring to FIG. 8, ion generator 100 further includes a clip 70. The ion generator 100 is mounted inside a pocket 85 provided in the garment 80 by a clip 70. By mounting the ion generating apparatus 100 in the pocket 85 in this way, the user can carry and use the ion generating apparatus 100. The ion generator 100 may employ a configuration that does not include the clip 70. The clip 70 may be configured to be detachable from the ion generator 100.

  In this case, since a space is secured near the side surface where the suction port 30 of the ion generator 100 is formed, the suction port 30 is not easily blocked by the clothing 80 and the pocket 85. For this reason, it is suppressed that the capability to inhale air from the suction inlet 30 falls.

  As described above, in the first embodiment, in one case 1, the substrate 11 having the surface 11 a provided with the ion generator 15 and the air sucked from the suction port 30 are directed toward the blower outlet 40. A blower fan 3 for blowing air is accommodated. And the ventilation fan 3 is arrange | positioned so that the air from the ventilation fan 3 may flow along the surface 11a of the board | substrate 11 in the case 1. FIG. For this reason, one surface of the substrate 11 can be used as an air passage for transporting ions to the outside. Therefore, according to this Embodiment 1, size reduction of the ion generator 100 can be achieved.

  Since the space between the surface 11a of the substrate 11 and the surface 1f of the case 1 is used as an air passage, it is not necessary to separately provide a member for forming the air passage.

  Since the blower fan 3 is disposed in a region where the air passage is formed in the thickness direction of the ion generator 100, the ion generator 100 can be thinned.

  Since the high voltage generator 6 is disposed so as to protrude from the surface 11a, it is possible to suppress an increase in the size of the ion generator 100 due to the height of the high voltage generator 6.

  The high voltage generator 6 is arranged so as to separate the air flow from the blower fan 3 to the outlet 40 into the first air flow and the second air flow. While suppressing the increase, the flow velocity of the air flowing through the air passage can be increased. Furthermore, since positive ions and negative ions are released to the outside from another path, it is possible to suppress the binding of positive ions and negative ions in case 1. Therefore, it is possible to increase the amount of ions emitted from the ion generator 100.

  Since the positive side rectifying element 5a and the negative side rectifying element 5b are arranged in a state embedded in the thickness direction of the substrate 11 from the surface 11a, the air from the blower fan 3 by the positive side rectifying element 5a and the negative side rectifying element 5b. It can suppress that the flow of is obstructed.

  Since the suction port 30 is formed in the side surface 1c of the case 1, it is possible to prevent a reduction in the ability to suck air into the case 1 when the ion generator 100 is carried. Therefore, the convenience when the user wears the ion generator 100 can be enhanced.

FIG. 10 is a perspective view of the ion generating element shown in FIG. Referring to FIGS. 9 and 10, ion generating element 20 a is arranged such that positive-side rectifying element 5 a and negative-side rectifying element 5 b have an angle with respect to the Y direction. With such an arrangement, the ion generating element 20a can reduce the width dimension W of the ion generating element 20a as compared with the case where the energization direction is arranged parallel to the Y direction.

  As described above, in the modification of the first embodiment, the width dimension W of the ion generating element 20a can be reduced, and the ion generating apparatus 100 can be further downsized.

  In addition, the positive ion discharge part 4a is arrange | positioned in the blower outlet 40 side in a X direction rather than the connection location of the positive ion discharge part 4a and the positive side rectifier 5a, and the negative ion discharge part 4b is the negative ion discharge part 4b. You may arrange | position at the blower outlet 40 side in a X direction rather than the connection location with the negative side rectifier 5b.

  FIG. 11 is a perspective view of an ion generator according to Embodiment 2 of the present invention. Referring to FIG. 11, ion generating device 100 a is formed with a suction port 30 a instead of suction port 30. The suction port 30a is formed in the main surface 1e of the ion generator 100a.

  The air sucked from the suction port 30 a is introduced into the blower fan 3 from the suction port 30 a side of the blower fan 3.

  As described above, in the second embodiment, it is not necessary to secure a space for introducing air between the battery 7 and the blower fan 3. Therefore, since the distance between the battery 7 and the blower fan 3 can be shortened, the thickness can be further reduced.

  In the above embodiment, the ion generator that generates ions combined with moisture in the air has been described as an example of the charged particle generator according to the present invention. However, the charged particles generated in the present invention are, for example, electrostatic It also includes charged fine particle water containing radical components generated by the atomizer.
