The present invention relates to an acidic component generator configured to discharge electricity to generate an acidic component.
As a prior art, for example, JP2010-196959A discloses a device configured to discharge electricity to generate an acidic component such as nitrate ion or nitrogen oxide.
In order to discharge electricity to generate a large quantity of acidic component, it could be thought to increase an voltage applied to an electrode, but there is a concern that an arc discharge would occur in this case. If such arc discharge occurs, it is difficult to generate the large quantity of acidic component as a result of wasted energy consumption. Additionally, there are problems of uncontrollable electric discharge and generation of sounds.
The present invention has been achieved in view of the above circumstances, and an object thereof is to provide an acidic component generator which enables generating a large quantity of acidic component while suppressing occurrence of an arc discharge.
An acidic component generator of the present invention comprises a discharge electrode and a voltage supply. The voltage supply is configured to apply a high frequency voltage to the discharge electrode to discharge electricity, thereby generating an acidic component.
Another acidic component generator of the present invention comprises a discharge electrode, a counter electrode facing the discharge electrode, and a voltage supply. The voltage supply is configured to apply a high frequency voltage to the counter electrode to discharge electricity, thereby generating an acidic component.
In addition, the voltage supply is preferably configured to apply the high frequency voltage having a frequency in a range of 50 kHz to 250 kHz.
In addition, the voltage supply is preferably configured to apply the high frequency alternating-current voltage.
In accordance with the present invention, it is possible to generate a large quantity of acidic component while suppressing occurrence of an arc discharge.
Embodiments of the present invention will be described with reference to accompanying drawings.
An acidic component generator of a first embodiment as shown in
The discharge electrode 1 is made of metal, but a shape thereof is not especially limited. As an example, it may be an electrode like a straight piece of which a head “T” is sharpened like a cone.
The counter electrode 2 is shaped like a ring, and is provided at a position opposed to the head of the discharge electrode 1 with the counter electrode 2 grounded. Moreover, the counter electrode 2 is configured to generate a potential difference between the counter electrode 2 and the discharge electrode 1. That is, the voltage applied from the voltage supply 3 is to be discharged toward an outside of the counter electrode 2.
The voltage supply 3, for example, is formed of an electronic oscillator or the like which includes a piezoelectric element. The voltage supply 3 is connected to the discharge electrode 1.
The voltage applied from the voltage supply 3 to the discharge electrode 1 is a high frequency voltage having a frequency in a range of 50 kHz to 250 kHz. When a frequency of the above voltage is less than 50 kHz, there is a possibility that an acidic component is not effectively generated, because the accumulate of an air ion, which is generated in the air, such as a nitrogen ion and an oxygen ion is reduced between electrodes which are the head T of the discharge electrode 1 and the counter electrode 2. Also when the frequency is more than 250 kHz, there is a possibility that an arc discharge tends to occur owing to change in state of electric discharge. Although the voltage is an alternating-current voltage where a center value thereof locates at 0 V as shown in
The voltage supply 3 is configured to apply the high frequency voltage to the discharge electrode 1 to discharge electricity, and therefore it is possible to generate the acidic component such like nitrate ion or nitrogen oxide of nitrogen dioxide or the like. The acidic component such like nitrogen dioxide or nitrate ion is, for example, to be supplied to hair, skin, head skin or the like. It is known that when the healthy hair, skin, head skin or the like has an alkalinity, resistance thereof against microorganism such like bacteria and fungus becomes weaker. By supplying the generated acidic component onto hair, skin, head skin or the like, it is possible that hair, skin, head skin or the like becomes to have mild acidity.
In the present embodiment, in order to discharge electricity, the high frequency voltage is applied to the discharge electrode 1, and therefore it is possible to suppress the transition of the discharge to an arc discharge. That is, as shown in
Even when the voltage applied to the discharge electrode 1 is a negative voltage at all times as show in
Even when the applied voltage is higher than the discharging start voltage “A” as shown in
Also in the present embodiment, since the voltage supply 3 is configured to apply the high frequency voltage having the frequency in the range of 50 kHz to 250 kHz, it is possible to generate the large quantity of acidic component and also to reduce a cost and size for the voltage supply 3.
In addition, the counter electrode 2 of the present embodiment is provided to enhance electric field strength between the counter electrode 2 and the discharge electrode 1 to generate the large quantity of acidic component, and may be omitted.
A second embodiment is now explained. In the following embodiment, like kind elements are assigned the same reference numerals as depicted in the first embodiment, and redundant explanation is omitted.
In an acidic component generator according to the present embodiment shown in
In the present embodiment, it is possible to suppress an arc discharge and to generate a large quantity of acidic component like the first embodiment.
Additionally, in each of the embodiments described above, a voltage applied from a voltage supply 3 to a discharge electrode 1 or a counter electrode 2 may be a high frequency voltage having a frequency out of a range of 50 kHz to 250 kHz.
