Problems solved by technology

[0020] However, in the prior art described above, since a current flows between the two electrodes and a discharge occurs in the air existing between the two electrodes, negative ions are also generated near the electrodes to which 0V or a positive voltage is applied. The negative ions do not disappear, resulting in the generation of a large amount of ozone or nitrogen oxides
[0021] In addition, due to the current flowing between the two electrodes, if the electrodes are touched by mistake, there will be a problem of electric shock
[0022] In addition, since the resistance of the air changes due to temperature and the discharge is unstable, it is difficult to obtain negative ions stably.

Embodiment approach 1

[0084] refer to figure 1 , The negative ion generator 10 of Embodiment 1 has a case 1 , needle electrodes 2 , a counter electrode 3 , an insulator 4 , a support member 5 , a power supply circuit 6 , and wiring 7 , 8 .

[0085] The insulator 4 , the support member 5 and the power circuit 6 are fixed on the bottom surface 1A of the box body 1 . The case 1 has an opening 11 . The needle electrode 2 is made of tungsten with a diameter of 0.5 mm to 1.0 mm. In addition, the needle electrode 2 has a pointed tip 2A, and the tip 2A is fixed to the support member 5 so as to face the opening 11 of the case 1 . Also, the needle electrodes 2 are not covered with an insulator. In addition, the needle electrode 2 is not limited to tungsten, and may be any electrical conductor having a high density and a high heat-resistant temperature.

[0086] The counter electrode 3 is covered with an insulator 4 and arranged at a predetermined distance from the needle electrode 2 . The insulator 4 c...

Embodiment approach 2

[0150] refer to Figure 9 , negative ion generator 10A of Embodiment 2 is a device in which insulator 9 is added and insulator 4 is removed in negative ion generator 10 , and the others are the same as negative ion generator 10 .

[0151] The insulator 9 covers the body part 2C except the front end part 2A and the rear end part 2B of the needle electrode 2 . The body portion 2C of the needle electrode 2 is covered with the insulator 9 to constitute the negative electrode 20 . The negative electrode 20 is fixed to the support member 5 by penetrating the support member 5 with the body portion 2C and the insulator 9 . Rear end 2B of needle electrode 2 is connected to wiring 7 .

[0152] In the negative ion generator 10A, the counter electrode 3 is not covered but the body part 2C of the needle electrode 2 is covered with the insulator 9 . That is, by covering a part of the needle-shaped electrode 2 with the insulator 9 , no current flows between the needle-shaped electrode 2 a...

Embodiment approach 3

[0168] Referring to FIG. 16 , negative ion generator 10B of Embodiment 3 is a device in which insulator 9 is added to negative ion generator 10 , and is the same as negative ion generator 10 in other respects.

[0169] The needle electrode 2 and the insulator 9 constitute a negative electrode 20 . Therefore, the specific material of the insulator 9 , the method of fixing the supporting member 5 to the negative electrode 20 and the method of connecting the negative electrode 20 and the wiring 7 are the same as those described in the second embodiment.

[0170] In negative ion generator 10B, needle electrode 2 and counter electrode 3 are covered with insulators 4 and 9, respectively. Therefore, the counter electrode 3 and the insulator 4 can be arranged at any position in the case 1 as described in the first embodiment.

[0171] In the negative ion generator 10B in which the needle-shaped electrode 2 and the counter electrode 3 are covered by insulators 4 and 9, a negative volt...

Abstract

A negative ion generator comprising a needle electrode, a counter electrode, an insulator, a supporting member, a power supply circuit, and wiring. The counter electrode is covered by the insulator. The needle electrode is secured to the supporting member. The wiring is connected with the needle electrode and the wiring is connected with the counter electrode. The power supply circuit applies a negative voltage of -5 kV to -9 kV to the needle electrode through the wiring and applies the ground voltage (0V) to the counter electrode through the wiring.

Description

technical field [0001] The present invention relates to an ion generating device for generating negative ions or positive ions. Background technique [0002] Recently, interest in health devices has been increasing. As one of such health devices, there is a negative ion generator. The negative ion generating device applies voltage between two electrodes to generate negative ions in the air. [0003] Figure 32 Shown is the main part of existing negative ion generator. The existing negative ion generating device has a discharge needle 60 and a counter electrode 70 . The counter electrode 70 has a ring shape and is arranged in front of the front end 60A of the discharge needle 60 . The discharge needle does not cover the insulator, and the front end 60A is sharp. [0004] In addition, a negative voltage of about several thousand volts is applied to the discharge needle 60 through the wiring 61 . In addition, 0 V or a positive voltage is applied to the counter electrode 7...
