  The insertion hole 23a includes a guide groove 23c that guides the first terminal 27b and the second terminal 27c of the second connection connector 27 when the second connection connector 27 is inserted. Then, the positive terminal and the negative terminal (not shown) electrically connected to the secondary battery are exposed from the induction groove 23c.

  Next, the flow for assembling the ion generator 21 of the present embodiment will be described. First, the ion generation module 24 of the first embodiment is wound to obtain the ion generation module 24.

  Next, the winding portion 24 a of the ion generation module 24 is inserted into the housing 25, and the protruding portion 24 b of the ion generation module 24 is protruded from the opening of the housing 25. At this time, the air flow path 10 in the ion generation module 24 extends in the axial direction of the housing 25.

  Next, the protrusion 24b of the ion generation module 24 is inserted into the notch 26d of the main body 26a of the first connection connector 26, and the protrusion 24b is inserted into one of the first terminals 26b of the first connection connector 26. It is sandwiched between the end portion and one terminal of the second terminal 26c. As a result, the connection part 5a of the first electrode 5 of the ion generation module 24 is electrically connected to one end of the second terminal 26c, and the connection part 8a of the second electrode 8 of the ion generation module 24.

  Next, the first connection connector 26 is inserted into the main body 27 a of the second connection connector 27, and the other end of the first terminal 26 b of the first connection connector 26 is connected to the second connection connector 27. The second terminal 26 c of the first connection connector 26 is electrically connected to the second terminal 27 c of the second connection connector 27. Thereby, the ion generation module assembly 22 can be obtained.

  Next, the second connection connector 27 in the ion generation module assembly 22 is inserted into the insertion hole 23 a of the housing 23 b in the power supply device 23. At this time, the first terminal 27b and the second terminal 27c of the second connection connector 27 are respectively guided by the guide groove 23c of the insertion hole 23a, and the first terminal 27b of the second connection connector 27 is the power supply device.

Thereby, it can suppress that the 2nd connection connector 27 comes off from the power supply device 23, and can connect the ion generating module assembly 22 to the power supply device 23 reliably.

  In such an ion generator 21, the power supply device 23 side of the ion generation module assembly 22 is disposed in a higher temperature environment due to the heat generated by the power supply device 23 than the other side. Since the air flow path 10 of the present embodiment extends in the axial direction of the housing 25, the air actively flows from the other side to the power supply device 23 side in the air flow path 10. Flows (ie, convection occurs). As a result, more ions can be generated as compared with the case where the ion generation module 1 of the first embodiment is used.

  Moreover, since the ion generator 21 of the present embodiment has a simple configuration of the ion generator module assembly 22 and the power supply device 23, it can be carried and the usage environment can be further expanded.

The length of the protrusion 24b of the generation module 24 is set. That is, the protruding portion 24 b includes a deformable portion 24 c that enables the winding portion 24 a of the ion generation module 24 to swing with respect to the power supply device 23. Then, a portion of the housing 25 that covers the deformable portion 24c of the ion generation module 24 (in this embodiment, the end of the housing 25 on the power supply device 23 side) allows deformation of the deformable portion 24c. It is said. The deformation | transformation permission part 25d is comprised with a universal tube, for example. With such a configuration, the winding unit 24 a of the ion generation module 24 and the housing 25 can be swung with respect to the power supply device 23.

In short, it is only necessary that the first electrodes 43 and the second electrodes 44 are alternately arranged so that discharge occurs.

<Embodiment 5>
The ion generation module of the present embodiment is configured to generate creeping discharge. FIG. 17 is a partially enlarged perspective view showing the ion generation module of the present embodiment.

  In the ion generation module 51 of the present embodiment, as shown in FIG. 17, the first electrode 53 is formed on one main surface of the flexible substrate 52, and the second electrode is formed on the other main surface of the flexible substrate 52. In this configuration, the electrode 54 is formed. With such a configuration, creeping discharge is generated between the first electrode 53 and the second electrode 54, and ions can be generated. Moreover, since the ion generation module 51 of the present embodiment is also made of a flexible printed board, the use environment can be expanded.

  As with the ion generation module 41 of the fourth embodiment, the ion generation module of the present embodiment can also be used in a wound form.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described configuration, and modifications can be made without departing from the technical idea of the present invention. It is also possible to combine the above embodiments.

  For example, in the above embodiment, DC power is supplied to the first electrode and the second electrode, but AC power may be supplied.
