It is a schematic sectional drawing which follows the VI-VI line of a schematic plan view (A) and FIG. 2 (A) which shows the structure of the bottom plate of the case of an ion generator. It is a functional block diagram of an ion generator, and is a figure showing electrical connection of each functional element. It is a side view of the cleaning tool which concerns on this invention. It is the top view and some cross-sectional side view of a cleaning tool. It is an operation | movement figure at the time of cleaning of the cleaning tool. It is a front view of the conventional keyboard cleaning tool.

  Here, the structure of an ion generator to which the present invention is applied will be described.

  FIG. 1 is a perspective view showing ion generating elements 10a and 10b constituting an ion generating device. The ion generating elements 10a and 10b are composed of a discharge electrode 2 located at the center, an induction electrode 1 having a predetermined distance from the discharge electrode 2, and a support substrate 3. The ion generator 30 has two ion generating elements 10a and 10b, each for generating positive ions and negative ions by corona discharge or the like.

  As an example, the induction electrode 1 is made of a metal plate and has a plurality of circular electrode through holes 1 a provided in the flat plate portion corresponding to the number of discharge electrodes 2. Ions are generated by corona discharge at the end face of the electrode through hole 1 a in the discharge electrode 2 and the induction electrode 1. The electrode through hole 1a is an opening for discharging ions from the ion generating elements 10a and 10b to the outside. The flat plate portion of the induction electrode 1 is made of a perforated sheet metal. As an example, the size of the electrode through hole 1a is preferably 10 to 15 mm in diameter. In this case, since the outer diameter of the brush portion is 10 to 15 mm in diameter, the outer diameter of the brush portion is used to insert the brush portion into the electrode through hole 1a. It is formed smaller than 1a. Moreover, the induction electrode 1 has the bending part 1b which bent a part of metal plate to the substantially right angle with respect to the flat plate part in both ends as an example. The support substrate 3 has a through hole (not shown) for inserting the discharge electrode 2 and a substrate through hole 3b for inserting the insertion portion of the bent portion 1b.

  In this example, the discharge electrode 2 has a diameter of 0.5 mm and a length of 3 mm. The discharge electrode 2 has a needle-like tip. The acicular discharge electrode 2 is supported by the support substrate 3 in a state of being inserted or press-fitted into a through hole (not shown) of the support substrate 3.

  The discharge electrode 2 of the ion generating element 10a for generating positive ions serves as a positive discharge electrode, and constitutes a positive ion generating part (positive electrode pair) together with the induction electrode 1 of the ion generating element 10a. Further, the discharge electrode 2 of the ion generation element 10b for generating negative ions is a negative discharge electrode, and constitutes a negative ion generation part (negative electrode pair) together with the induction electrode 1 of the ion generation element 10b.

  A common induction electrode 1 is provided for a plurality of discharge electrodes 2 for generating positive or negative ions of the same polarity.

  Next, the configuration of the ion generator will be described.

  The plan view of FIG. 2 (a) and the sectional view of FIG. 2 (b) will be described. FIG. 2 (b) is a schematic sectional view taken along the line VI-VI of FIG. As shown in FIG. 2, an ion emission hole 21 d is formed in the outer case 21 of the ion generator 30. The ion emission hole 21d is disposed immediately above the electrode through hole 1a of the induction electrode 1. Thereby, the discharge electrode 2 can be seen from the outside of the ion generator 30 through the hole 21d for ion emission and the electrode through hole 1a.

  Here, an example of an ion generator will be described. The ion generator is an electrical device that is equipped with an ion generator and discharges ions released from the electrode through holes 1a of the ion generating elements 10a and 10b into a room by blowing air from a blower. In the ion generator, the air in the room is sucked into the ion generator through the air filter by the operation of the blower, and the ions generated by the ion generator 30 are included in the air and released into the room. The opening of the mesh of the net used for the air filter on the windward side of the blower is about 50 to 400 μm, and fine dust and substances in the air whose size is smaller than the opening size cannot be removed, and pass through the electrode. It enters from the through hole 1a and accumulates in the peripheral portion of the electrode, the support substrate 3 and the like.

  When the ion generator is operated, fine dust and substances that have passed through the air filter are adsorbed and deposited on the discharge electrode 2 due to static electricity when passing through the ion generating elements 10a and 10b to become foreign matters. By adhering to the discharge electrode 2, the generation of ions is reduced or stopped. Therefore, in order to stably release ions for a long period of time, it is particularly necessary to remove foreign matters that have adhered to or deposited on the discharge electrode 2.

  As shown in FIG. 2B, dust or the like entering the ion generating elements 10a and 10b from the electrode through hole 1a needs to be removed by putting a brush through the electrode through hole 1a. Can be removed by inhaling with a cleaning tool. Alternatively, dust or the like on the support substrate 3 can be removed by blowing it away with a cleaning tool.

  Next, the state of electrical connection of each functional element will be described.

  FIG. 3 is an example of a functional block diagram showing electrical connection of the ion generator 30. The ion generator 30 includes an exterior case 21, ion generation elements 10 a and 10 b, a high voltage transformer 11, high voltage circuits 12 a and 12 b, a power input connector 22, and a power circuit 23. Note that a part of the power input connector 22 is disposed in the outer case 21, and the other part is exposed to the outside of the outer case 21, so that a power source can be connected to the connector from the outside.

  The power input connector 22 is a part that receives supply of input power, and is electrically connected to the power circuit 23. The power supply circuit 23 is electrically connected to the primary side of the high voltage transformer 11. The high-voltage transformer 11 boosts the voltage input to the primary side and outputs it to the secondary side. One side of the secondary side of the high-voltage transformer 11 is electrically connected to the induction electrode 1 of the ion generating elements 10a and 10b. The other secondary side of the high-voltage transformer 11 is electrically connected to the positive discharge electrode 2 of the ion generating element 10a for generating positive ions through the positive high voltage circuit 12a, and through the negative high voltage circuit 12b. It is electrically connected to the negative discharge electrode 2 of the negative ion generating element 10b.

  The positive high voltage circuit 12 a applies a positive high voltage to the induction electrode 1 to the positive discharge electrode 2, and the negative high voltage circuit 12 b applies to the induction electrode 1 to the negative discharge electrode 2. Thus, a high negative voltage is applied. Thereby, positive and negative bipolar ions can be generated.

  Hereinafter, embodiments of the cleaning tool of the present invention will be described with reference to the drawings.

The bristles 110a are arranged in a ring shape. A plurality of brush bristles 110a are arranged and planted around the opening of the through hole 125a on the end surface of the base portion 122a. The outer diameter of the through-hole 125a is approximately 3 mm, but may be changed as appropriate depending on the inner diameter of the brush portion.

  The material of the brush hairs 110a and 110b is preferably nylon, and the hair diameter is preferably 0.2 mm. The brush bristles 110a of the brush part 111 are formed of thick brush bristles and a flexible material. The brush bristles 110b of the brush part 112 are thinner than those of the brush part 111, and are formed of a flexible material. The outer diameters of the brush part 111 and the brush part 112 are preferably 9.5 mm or less so as to enter from the opening of the electrode through hole 1a in FIG. The inner diameter of the brush portion 111 needs to be larger than the outer diameter of the through hole 125a, and is preferably 5 mm or more. The length from the surface of the base part 122b to the tip of the brush bristle 110b of the brush part 111 and the brush part 112 is 10 mm or more so as to reach the corner of the support substrate 3 from the opening of the outer case 21.

The brush portion 112 attached to the other end of the main body 101 has the same configuration and shape as the brush portion 111 attached to the one end, but has a shape without the through-hole 125a. When the central portion is strongly pressed, air is ejected from the brush portion 111 through the through hole 125a of the head portion 124a, so that dust and foreign matters attached to the device can be blown off and removed.

  In addition, the thickness of the brushes attached to both ends of the main body 101 is formed with a bundle of thick bristles, and the other is formed with a bundle of bristles that are thinner than the other, so that dust and foreign matter adhered to the device Depending on the conditions to be removed, it can be used properly according to the conditions of removal, such as the degree, size, degree of finishing and degree of adhesion.

6A is a diagram showing a state before electrode cleaning, FIG. 6B is a diagram showing that the electrode is being cleaned, and FIG. 6C is a diagram showing a state in which the center portion of the main body 101 is pushed and foreign matter is blown away and removed. FIG. 6D is a diagram showing a state in which foreign matter is sucked into and removed from the inside of the main body 101.
Next, a state where foreign matters such as dust on the electrode are removed will be described with reference to FIG.

  As shown in FIG. 6 (a), dust or the like adheres to the outside of the discharge electrode 2, high-voltage electricity leaks, the discharge state deteriorates, and the discharge voltage waveform and the discharge current waveform change from the original design. End up. Further, when a hair spray or the like is used in the vicinity of the ion generator, foreign substances such as silicon contained in the hair spray or the like adhere to the discharge electrode 2 and an insulating film is formed, resulting in a poor discharge state. Since the voltage applied to the discharge electrode 2 is determined by the circuit, when the voltage waveform or current waveform changes, the initial discharge energy is not supplied, and as a result, the initial number of ions cannot be obtained. If the fouling is significant, there is a risk that no discharge will occur.

  In this case, as shown in FIG. 6 (b), the longitudinal direction of the brush bristles 110b of the brush part 111 and the longitudinal direction of the discharge electrode 2 are made substantially parallel to each other and rubbed in the left-right direction X or the up-down direction Y. Foreign matter such as dust attached to the discharge electrode 2 is rubbed and falls onto the support substrate 3. Thereafter, when the bottom surface of the support substrate 3 has an opening through which foreign matter accumulated can be discharged, the central portion of the main body 101 is pushed in as shown in FIG. Is ejected to the tip of the brush portion, and the foreign matter is blown away and removed. On the contrary, as shown in FIG. 6 (d), when the tip of the brush portion is attached to the bottom surface and the central portion of the main body 101 is pushed in, after the pressing force at the central portion of the main body 101 is removed, the central portion is elastically restored to the original. Attempting to return to the shape, air is sucked into the main body 101 from the through hole 125a, and at the same time, foreign matter is sucked and removed. The foreign matter that has entered the main body 101 from the through hole 125a pushes the central portion of the main body 101, blows the air inside the main body 101 from the through hole 125a to the tip of the brush portion, and blows the foreign matter into a trash box or the like. throw away. Alternatively, the support at either end of the main body 101 is pulled out from the main body 101 and the foreign matter accumulated inside is discarded into a trash can or the like.

  In the embodiment, the main body 101 is a resin material having soft elasticity, but the material may be rubber having elasticity or the like.

  In this embodiment, the main body 101 is formed in a circular arc shape at both ends and the central portion, but may be a straight line. In the embodiment, the cross section in the longitudinal direction of the main body 101 is circular, but may be rectangular or polygonal.

  Note that the support body 120 may be used as the support body 121 so that only the through hole 125a is closed with a conical tip like a toothpick. In this case, by closing the through hole of one of the brush portions of the main body 101 so that the structure of the brush portion is different, the brush portion 112 can also blow off and suck in foreign matter in the same manner as the brush portion 111. This makes it possible to perform various cleaning operations and efficiently perform cleaning.

  In addition, you may decide to replace | exchange the support body which planted the brush part, and to change and use the arrangement | sequence of a bristle, the diameter of a bristle, length, quantity, a softness | flexibility, etc. according to a use application.

  In the present embodiment, an ion generator has been described as an example of an electric device. However, the present invention is not limited to this, and an air purifier or an air conditioner ( Air conditioners), refrigeration equipment, vacuum cleaners, humidifiers, dehumidifiers, and the like, and any electrical equipment that has an ion generator for sending ions in an air stream.
