  Hereinafter, the details of the static electricity removing apparatus for human body wearing according to the present invention will be described with reference to the accompanying drawings.

  The static eliminator for human body according to the present invention has a means for mounting on the human body or a portable configuration, and removes static electricity from the human body by positive ions and negative ions generated from the ion generating element. The ion generating element has a configuration that is a fine electrode ion generating element having a discharge electrode having fine protrusions of 0.05 mm or more and 1 mm or less, an induction electrode, and a dielectric sandwiched between them. .

  As shown in FIGS. 1 and 2, the static electricity removing device 1 for mounting on a human body according to the present invention mainly includes a main body 2 and mounting means 3.

  The main body 2 includes an ion generating element 4 that generates positive ions and / or negative ions, a power source 5, and a battery 6. Reference numeral 7 denotes a protective resistance for protecting the human body (preferably a resistance of 1 MΩ).

  As shown in FIG. 3, the principle of static electricity removal is to connect the ground wire of the static electricity removing apparatus 1 for wearing the human body to the human body through a high (protective) resistance, and thereby the ion current Ii released into the atmosphere. Since an equivalent current flows through the human body Ih, static electricity is removed.

  The mounting means 3 has a wristband configuration in this embodiment, and can be mounted by winding the wristband portion 31 around an arm (wrist).

  The wristband portion 31 is formed from a material such as a synthetic resin, a natural material, a mixture thereof, or a leather, and in the case of a non-conductive material, a conductive material may be contained. In addition, it is preferable to have a buckle portion, a stopper portion, a hook portion, etc. for convenience during attachment / detachment. Furthermore, it is preferable that the size and the like can be adjusted according to the part to be worn by the wearer (the wrist in the present embodiment), or that the material and configuration can be expanded and contracted.

  For the ion generating element 4, a linear metal having a plurality of fine protrusions (0.05 mm or more and 1 mm or less) on the discharge electrode is most effective, and various ceramics, glass, 0.05 mm or more and 1 mm or less in thickness are used as the dielectric. A form in which a ground electrode is placed so as to surround the discharge electrode using a dielectric such as mica and the dielectric (layer) can generate the highest concentration of ions. When the protrusion is less than 0.05 mm, the distance is almost the same as the film thickness of the dielectric (layer), so the protrusion does not work effectively and discharge occurs over a wide range of the entire linear metal electrode. As a result, ozone concentration rises and is not practical. When the thickness exceeds 1 mm, the electric field concentrates at the tip as in the case of using a needle-like electrode.

  The discharge electrode used in the present invention may be linear, curved, corrugated, sawtooth, pulse wave, or the like as long as it is disposed on a plane in one direction.

  The ion generating element 4 includes a positive electrode generating fine electrode ion generating element and a negative ion generating micro electrode ion generating element in which a ground electrode serving as a counter electrode and a counter electrode is sandwiched between thin dielectric films (layers). Ion generating element, effective arrangement of the ion generating element, a power source for applying a waveform-controlled voltage to the discharge electrode, and also for efficiently transporting the generated positive and negative ions to the charged object as the object The best static neutralization characteristics are shown when it is composed of the airflow generator.

  Such an ion generating element 4 applies various voltages with controlled waveforms to the discharge electrodes. The voltage and frequency are set to appropriate values in order to generate substantially the same amount of positive and negative ions. In order to suppress the generation of ozone harmful to the human body, it is most effective to periodically apply positive and negatively biased pulse voltages of 10 microseconds or less, and in this case, per ion generating element. By installing positive and negative electrodes, positive and negative ions can be generated.

  The ion generating element 4 is a fine electrode ion generating element having a discharge electrode having fine protrusions, an induction electrode, and a thin dielectric film sandwiched between them, as shown in FIG. The positive electrode generating fine electrode ion generating element 41a having a pulse waveform in which the voltage applied to the positive electrode is positively biased, and the negative ion generating element having a pulse waveform in which the voltage applied to the discharge electrode is negatively biased. The fine electrode ion generating element 41b is configured as one set, and the ion generating element 4 including the positive ion generating fine electrode ion generating element 41a and the negative ion generating fine electrode ion generating element 41b as one set is provided. Arranged. Even one (one set) shows the effect, but by disposing a plurality (multiple sets), it is possible to further improve the static elimination performance. As for the arrangement of the electrodes at this time, positive or negative ions may be generated by applying an AC voltage or a high frequency voltage to the two-wire type ion generating element shown in detail in FIG. Alternatively, negative monopolar ions may be generated alternately. An arrangement that can provide a good charge removal effect can apply positive and negative pulse voltages to the three-line type ion generating element shown in FIG. 6 to generate positive and negative ions at high concentrations.

  FIG. 5 shows the structure of the two-wire type ion generating element 4. The voltage is applied to the discharge electrode 40 via the lead wire 42. A ground electrode 43 is arranged around the discharge electrode 40 so as to surround the thin dielectric (layer) 45. The interval between the discharge electrode 40 and the ground electrode 43 is made as small as possible within a range where stable discharge can be obtained. This concentrates the electric field at the tip and increases the efficiency of ion generation even at a low voltage. Since the dielectric 45 has high insulation, there is no safety problem even if the discharge electrode 40 overlaps the ground electrode 43 via the dielectric 45. The ground electrode 43 is preferably grounded via the lead wire 44, but the absolute value of the potential difference is important for the generation of ions, and this is not limited as long as the potential difference between the two electrodes is maintained. In the present invention, as shown in FIG. 4, as the power source 5, a positive pulse high voltage generating power source 51a is connected to the positive electrode generating fine electrode ion generating element 41a to generate the negative electrode generating fine electrode ions. A negative pulse high voltage generating power source 51b is connected to the element 41b.

  FIG. 6 shows the structure of a three-wire type ion generating element. Positive and negative pulse voltages are applied to the discharge electrodes 40a and 40b. Similar to the two-wire type, the ground electrode 43 is disposed so as to surround the thin dielectric 45. For example, when an AC voltage is applied to a two-wire type element, the positive and negative ionization voltages are different, so that a bias of the center voltage is required for controlling the ion balance. Since positive and negative ions can be generated in the element and the respective ion concentrations can be controlled independently by the respective voltages, the controllability of the ion balance is improved.

  As the high-voltage power supply 5, it is preferable to use a laminated piezoelectric transformer because it contributes to downsizing. In order to save power, measures such as monitoring the increase in ion current value (charging → ion current increase) and reducing the output voltage when there is no static electricity, or widening the oscillation interval to thin out the output oscillation Can also be taken.

  The battery 6 is preferably a rechargeable battery using a secondary battery such as a lithium ion battery. In the case of the rechargeable type, a cradle-type charger can be used, and an airflow generation means such as a propeller fan can be attached to the charger so as to function as a positive / negative ion generator during charging.

  As described above, the static electricity charged on the human body can be removed by using the static eliminator 1 for wearing on the human body according to the present invention.

  The static eliminator 1 for human wear of the present invention takes the following aspects within the scope of the present invention.

Such configurations include clips, hooks, planar fasteners, buttons, and the like.

  The mounting means 3 may be fixed to the main body 2 or may be detachably attached. When it is possible to attach and detach, the mounting means 3 can be removed from the main body 2 and the static eliminating device 1 can be in the state of only the main body 2, so that the mounting means does not become an obstacle during use other than mounting. Furthermore, it can be configured to be exchangeable with the mounting means 3 having another configuration. For example, the mounting position can be changed from an arm to a leg by exchanging from a wristband type to a legband type. According to this aspect, it is effective when, for example, it is desired to change the mounting position depending on the work content during work.

  Moreover, it is not limited to being mounted on the human body by the mounting means 3, but can be carried by a portable configuration such as a key holder, a mobile phone strap, a ballpoint pen, and accessories (case, spare battery, etc.) of a mobile terminal. When it is set as the portable structure, it is preferable that the static electricity removal apparatus 1 for human body mounting | wearing is a structure operated with a hand.

  The dielectric is not limited to inorganic materials such as various ceramics, glass and mica, but may be organic materials such as polyimide. Since the dielectric is composed of a dielectric film (layer) such as ceramics, glass, or mica, ion generation efficiency is increased.

  A contact for grounding with a grounded lead wire can also be provided so as to be able to cope with work in an environment sensitive to electrostatic disturbance. The lead wire is preferably provided with a protective resistance for protecting the human body (preferably a resistance of 1 MΩ). In addition, a line for supplying charging power to the lead wire can be mixed.

  In order to know the current charge level of the human body, that is, to determine whether there is a danger potential when performing a work sensitive to static electricity, a display means for residual potential can be provided. The residual potential is preferably displayed or warned by a light source such as an LED or a buzzer sound. As a result, it is possible to reduce the electrostatic breakdown by grasping the charging state before performing work and waiting for the start of the work until the completion of static elimination or stopping the work depending on the charging state.

  The static eliminator for wearing of the human body of the present invention not only removes static electricity during work sensitive to static electricity but also charges the human body positively by operating it so as to release a large amount of negative ions. It can also be used for hay fever countermeasures that repel the potential of pollen, which is often charged, to reduce the approach of pollen. In particular, since it is not a technique for applying voltage to the human body, there is no variation due to the constitution of the wearer, and since it is not a technique for capturing and adsorbing powder, there is no problem with hygiene.

  In addition, if the static eliminator for wearing on the human body is attached to a part close to the eye and nose, such as the face, head, neck, and chest, the eye nose is the most important part for preventing the adhesion of powder and particles such as pollen. Can prevent the adhesion of powders and granules in the plant, so it is extremely effective as a countermeasure against allergic symptoms such as hay fever, bronchial asthma and cancer.

  When using for the prevention of hay fever by preventing the adhesion of powder / particles, in order to know whether the current polarity of the human body is positive, that is, whether the adhesion of powder / particles can be prevented In order to ascertain this, a polar display means can be provided. The polar state is preferably displayed or warned by a light source such as an LED or a buzzer sound. Accordingly, it is possible to grasp the polarity state before going out, and when the human body has a negative polarity, it is possible to further prevent the adhesion of powder and granules by waiting for going out until the body becomes positive.

  The static eliminator for mounting on the human body of the present invention is not only mounted on or carried by the human body, but is also mounted on other animals such as animals and plants such as pets and foliage plants, cars and car seats / seat belts, etc. Removal can also be performed. In the case of these modes, the mounting means 3 naturally takes a configuration corresponding to the mounted object. When attaching to articles that come into contact with the human body such as car seats, seat belts, chairs, desks, work tables, etc., it is sufficient that the main body 2 can be placed or fixed so that it does not fall off. Adhesive means such as double-sided tape and sticking means such as a surface fastener may be mentioned, and they may simply be placed on the top surface of the article, or may be mounted in a recess, groove or pocket formed or added to the article.
