Description

  The present invention relates to an electrostatic atomizer that generates nanometer-sized charged fine particle water by an electrostatic atomization phenomenon.

  Conventionally, by applying a high voltage to the discharge electrode to which water is supplied and discharging it, the voltage is applied to the water held by the discharge electrode and atomized by the electrostatic atomization phenomenon to charge nanometer size. In the electrostatic atomizer that generates fine particle water (nano-size mist), the generated charged fine particle water is strongly acidic fine particles. For example, if this is applied to the hair, it can give gloss or firmness. The charged fine particle water also has other effects such as a deodorizing effect. Therefore, the electrostatic atomizer can obtain various effects by being mounted on various devices such as a hairdressing device such as a hair dryer and a hair setter, and an air purifier (see, for example, Patent Documents 1 and 2). ).

By the way, as a method of supplying water to the discharge electrode of the electrostatic atomizer, for example, there is a method in which the water stored in the tank is sent to the discharge electrode by a supply tube such as a capillary tube that causes a capillary phenomenon. If the discharge electrode is positioned at a higher position than that, there is a problem that water is not satisfactorily supplied to the discharge electrode due to the influence of gravity.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  1 to 9 show an embodiment of the present invention. This example is a hair setter 10 equipped with an electrostatic atomizer 1. As shown in FIGS. 1 to 6, the hair setter 10 has a grip portion 11 that a user's hand grips at one end portion (base end portion) in the longitudinal direction and the other end portion (tip end portion) in the longitudinal direction. It has a hair styling part 12 that heats the user's hair and sets the hair. The hair setter 10 housing is pivotally supported by the gripping portion 11 so that the hair shaping portion 12 can freely come in and out so that the hair introduced from the direction perpendicular to the longitudinal direction of the hair setter 10 can be held by the hair shaping portion 12 at the tip. 2 blocks (main block 13 and presser block 14). Specifically, a flat plate-like heating plate 15 provided with a heater is disposed on each of the sandwiching surfaces 13a and 14a of the main body block 13 and the presser block 14 facing each other in the hairstyling unit 12. The main block 13 includes the electrostatic atomizer 1 and an operation switch 16 for operating the heater of the heating plate 15 and the operation of the electrostatic atomizer 1. Specifically, the electrostatic atomizer 1 is disposed between the gripping part 11 and the hairstyling part 12 in the main block 13 so as not to obstruct the hand holding the gripping part 11, and the operation switch 16 is a hand holding the gripping part 11. Is arranged in the gripping part 11 so that it can be operated satisfactorily.

  Here, as shown in FIG. 1, the electrostatic atomizer 1 includes a needle-like discharge electrode 3 that applies a voltage to supplied water, and a ring-like counter electrode 4 that is positioned opposite to the discharge electrode 3. A high voltage applying unit 5 that applies a high voltage between the discharge electrode 3 and the counter electrode 4, a tank 2 that stores water W, and a supply pipe 6 that supplies the stored water W in the tank 2 to the discharge electrode 3. It is comprised and comprises. In this example, the discharge electrode 3, the counter electrode 4, and the high voltage application unit 5 are integrated by a cover body 7 to prevent an electric shock to form an atomizing unit 8, and the main block 13 is seen in plan view. The electrostatic atomizer 1 is formed by one tank 2 disposed on the longitudinal axis of the two tanks and two atomizing units 8 disposed at equal intervals on the left and right sides of the axis. In addition, the said left-right direction shall say the direction orthogonal to the longitudinal direction of the hair setter 10 in the clamping surfaces 13a and 14a of the state mutually match | combined.

  The mechanism of generation of nanometer-sized charged fine particle mist (electrostatic atomization phenomenon) by the electrostatic atomizer 1 is supplied to the tip of the discharge electrode 3 by a voltage applied between the discharge electrode 3 and the counter electrode 4. The charged water is charged, the Coulomb force acts on the charged liquid, and the liquid level of the water supplied to the tip of the discharge electrode 3 rises locally in a cone shape with a sharp tip (Taylor cone). Nanometers that have radicals by concentrating charges at the tip of this Taylor cone and increasing the density, and repeating atomization and scattering (Rayleigh splitting) of the liquid due to the repulsive force of the increased charges. A size of charged fine particle mist (negative ion mist) is generated.

  A discharge port 17 provided in the main block 13 is arranged in the distal direction of the discharge electrode 3 in the atomization unit 8 housed in the main block 13. The discharge port 17 is inclined in the direction of the longitudinal direction of the hair setter 10 at the side periphery of the hair setting unit 12 (specifically, the tip is inclined in the direction away from the axis of the hair setter 10 and slightly toward the presser block 14). The charged fine particle mist scattered in the opening direction from the discharge port 17 can be efficiently applied to and attached to the hair held by the hair styling part 12.

  As shown in FIG. 8, the tank 2 has a flat rectangular tank case 20, and the water supply port 22 at the other end of the insertion tube portion 21 with one end inserted into the tank case 20 is connected to the tank case 20. It is made to project at one end of the. The tank case 20 is formed by joining a pair of halved cases 20 a and 20 b together, and the insertion tube portion 21 has a large number of water passage holes 23, and the insertion tube portion 21 has water absorption. A possible felt (not shown) is disposed, and one end of the insertion tube portion 21 is inserted into the tank case 20 through a water supply port 24 provided in the tank case 20 and is detachable from the tank case 20 by a bayonet structure. Has been. That is, when water is supplied to the tank 2, the water supply port 24 that appears when the insertion pipe portion 21 is removed from the tank case 20 is directed upward, and water is poured into the water supply port 24 from the outside. (See FIG. 17D). For convenience, the surface of the tank 2 that faces the bottom surface 18a of the tank storage portion 18 when the tank 2 is stored in a tank storage portion 18 to be described later is referred to as a bottom surface 2a, and the surface opposite to the bottom surface 2a is referred to as a top surface 2b. However, the bottom cylinder 2a of the tank 2 is formed with a through-cylinder portion 25 communicating with the inside and outside of the tank 2 so as to be drawn toward the top surface 2b. An air permeable film 26 that cannot pass water is attached to the projecting end of the cylinder passage portion 25 (the end portion on the top surface 2b side of the tank 2) to close the cylinder passage portion 25.

  The tank 2 is detachably accommodated in a tank accommodating portion 18 provided in the main block 13 as shown in FIG. The tank storage portion 18 is formed in a concave shape on the outer surface of the main block 13 opposite to the sandwiching surfaces 13 a and 14 a, and the tank storage portion 18 can be opened and closed by a lid 19. The lid 19 is attached to the tank storage portion 18 by engaging a locking portion 19 a provided on the back side with a locked portion 18 b provided inside the tank storage portion 18. The bottom surface 18a of the tank storage portion 18 is provided with a pair of locking hooks 18c to which locking protrusions 27 provided on the left and right side surfaces of the tank 2 are locked when the tank 2 is stored in the tank storage portion 18. It has been. Further, the tank connecting portion 9 is provided on the bottom surface 18 a of the tank storing portion 18 to which the water supply port 22 of the tank 2 is connected and attached when the tank 2 is stored in the tank storing portion 18. The other end of the supply pipe 6 whose one end is connected to the discharge electrode 3 of each atomizing unit 8 is connected to the tank connecting portion 9. The supply pipe 6 is constituted by, for example, a resin capillary (capillary that can cause capillary action).

  The hair setter 10 is used in such a posture that the holding surfaces 13a and 14a of the hairstyling part 12 are in a substantially vertical plane as shown in FIG. 7A (the horizontal direction of the housing faces the substantially vertical direction). In this case, at least one of the atomizing units 8 is positioned above the tank 2, and the stored water W in the tank 2 is sent to the discharge electrode 3 through the supply tube 6 by capillary action. If the prior art is adopted, water will not be satisfactorily supplied to the discharge electrode 3 due to the influence of gravity, but in this example, the stored water W in the tank 2 is forced to the discharge electrode 3. A water supply means for supplying and stably supplying the stored water W in the tank 2 to the discharge electrode 3 is employed, which will be described in detail below.

  That is, the water supply means is means for bringing the water W in the tank 2 to the discharge electrode 3 through the supply pipe 6 by the internal pressure of the tank 2 raised by heating and expanding the air A in the tank 2. is there. In this example, as the heating means for heating the air A in the tank 2, the heater of the heating plate 15, which is a heat generating part originally provided in the hair setter 10, is used, and the structure can be simplified by using the members as well. It has been. The operation of this water supply means requires the air A in the tank 2, but there is a storage means for storing a certain amount of water and air A in the tank 2 when the tank 2 is replenished with water. The air A is secured in the tank 2 to avoid malfunction of the water supply means. The storage means of this example is configured such that the tank case 20 is formed of, for example, a transparent or translucent material so that the water surface line of the internal water storage W can be visually confirmed from the outside. It is configured by adding a water replenishment mark (not shown) indicating the position of the line, that is, by replenishing water so that the user visually matches the water replenishment mark when refilling the tank 2. A fixed amount of water and air A are accumulated in the tank 2.

  In this way, a water supply means is adopted that brings the stored water W in the tank 2 to the discharge electrode 3 through the supply pipe 6 by the internal pressure of the tank 2 raised by heating and expanding the air A in the tank 2. As a result, even if the atomization unit 8 is positioned above the tank 2 due to the usage posture of the hair setter 10 on which the electrostatic atomizer 1 is mounted, the water storage W in the tank 2 is forcibly forced. It is possible to supply the discharge electrode 3 to stably supply the stored water W in the tank 2 to the discharge electrode 3 so that the electrostatic atomizer 1 and thus the hair setter 10 equipped with the electrostatic atomizer 1 can be secured. Has been.

  Here, when the operation of the electrostatic atomizer 1 is stopped by the operation switch 16 after the air A in the tank 2 is heated and expanded (that is, the use of the hair setter 10 is finished), the dotted line graph of FIG. As described above, the heating of the air A stops and the air A contracts, and the tank 2 is in a negative pressure state equal to or lower than the atmospheric pressure. When the inside of the tank 2 is in a negative pressure state and the air permeable membrane 26 is not covered with the water storage W in the tank 2, the outside air is introduced into the tank 2 through the air permeable membrane 26. Accordingly, the negative pressure state in the tank 2 is relaxed as shown by the solid line graph in FIG. 9, thereby preventing damage to the tank 2 due to the negative pressure. Usually, the hair setter 10 after use assumes a state in which the presser block 14 is placed on the bathroom vanity 40 with the main block 13 overlapping the presser block 14 as shown in FIG. 7B. In this case, since the tank 2 is in a posture in which the bottom surface 2a is positioned downward and the top surface 2b is positioned upward, the air permeable film 26 provided at the protruding end of the cylinder passing portion 25 is a tank in which air A is accumulated. It is assumed that the air permeable membrane 26 is kept in contact with the air A in the tank 2 so that the outside air is easily drawn into the tank 2.

  In addition, when the air A in the tank 2 is heated and expands and the internal pressure increases to the external pressure or more, a part of the air A in the tank 2 may escape to the outside through the air permeable membrane 26. When passing through the air permeable membrane 26, a certain osmotic pressure is required, and the air permeable membrane 26 becomes a so-called ventilation resistance when passing through the vent hole, and when the electrostatic atomizer 1 is used (that is, a hair setter). 10), the posture of the hair setter 10, and hence the tank 2 changes rapidly, and the air permeable membrane 26 does not keep in contact with the air A in the tank 2 (the state where it is covered by the water storage W in the tank 2). Therefore, when the internal pressure is increased, the internal pressure in the tank 2 is not drastically reduced by the air A flowing through the air permeable membrane 26.

  Hereinafter, other examples of the embodiment will be listed. In these drawings, the same parts as those in the previous example are denoted by the same reference numerals, description thereof is omitted, and different parts are described.

  In another example of the embodiment of FIG. 10, the arrangement of the air permeable membrane 26 is different from the previous example. The used hair setter 10 is normally placed on the vanity 40 in such a posture that the bottom surface 2a of the tank 2 is located below and the top surface 2b is located above as shown in FIG. 7 (b). Although assumed, as shown in FIG. 7C, the main body block 13 and the presser block 14 may be placed on the bathroom vanity 40 with the side surfaces thereof facing downward. In the latter case, the tank 2 has a posture in which the top surface 2b and the bottom surface 2a are inclined close to a vertical surface (the posture in which the horizontal direction of the top surface 2b and the bottom surface 2a is close to the vertical direction), In the case of the tank 2 of the previous example, the water storage W in the tank 2 covers the air permeable film 26 disposed at the left and right center part of the top surface 2b of the tank 2 as shown in FIG. Therefore, there may be a state in which the negative pressure in the tank 2 cannot be relieved because no outside air is introduced. In the example of FIG. 10, even in the latter state (FIG. 7C), at least a part of the air permeable membrane 26 is located in the air A layer in the tank 2 and is moved from the air permeable membrane 26 into the tank 2. The arrangement of the air permeable membrane 26 is devised so as to make it possible to relieve the negative pressure state in the tank 2 by introducing outside air.

  Specifically, in the example of FIG. 10A, the through-cylinder portions 25 including the air permeable membrane 26 are formed at both ends in the left-right direction of the tank 2. In this example, the two through-cylinder portions 25 having the air permeable membranes 26 are arranged in parallel so as to be positioned at both ends in the left-right direction of the two tanks 2, but the number is not limited to two and a plurality of them are provided. But you can. In the example of FIG. 10B, the through-cylinder part 25 is formed so as to have a long hole cross section that is long in the left-right direction, and the air-permeable membrane 26 is attached to the through-cylinder part 25 and closed. . In any example, the air permeable membrane 26 is disposed at both ends in the left and right direction of the tank 2 (at least a portion deviated from the left and right central portion in the left and right direction). However, at least a part of the air permeable membrane 26 can be left with a portion that is not covered with the water storage W in the tank 2 (that is, a portion through which the air A can pass). Thus, the negative pressure state in the tank 2 can be relaxed.

  Another example of the embodiment shown in FIGS. 11 to 13 is an example in which the water supply means is provided with an overheat preventing means for preventing overheating of the air A in the tank 2. The overheat preventing means in the example of FIG. 11 includes a heat insulating material 30 between the tank housing portion 18 housing the tank 2 of the main block 13 and the heater of the heating plate 15 of the heat generating portion that heats the air A in the tank 2. It is comprised by arrange | positioning. The overheat preventing means in the example of FIG. 12 is configured by providing an uneven shape on the bottom surface 2 a of the tank 2. Specifically, in this example, the protruding ribs 31 that are long on the left and right are arranged in parallel in the direction orthogonal to the left and right direction. According to this, the contact area of the tank 2 to the bottom surface 18a of the tank housing part 18 that receives heat from the heat generating part can be changed, and the amount of heat conducted to the tank 2 can be adjusted. Further, the overheat preventing means in the example of FIG. 13 is configured by providing heat radiation fins 32 on the top surface 2 b of the tank case 20 of the tank 2. Any of the overheat prevention means can adjust the temperature of the air A in the tank 2 to be heated so as not to become extremely high, and the tank 2 is excessively expanded due to excessive expansion of the air A in the tank 2 that has been abnormally heated. The risk of damage can be avoided. The electrostatic atomizing device 1 is provided by a heat generating part (not provided for the purpose of heating the air A in the tank 2 of the electrostatic atomizing device 1) originally provided in the device on which the electrostatic atomizing device 1 is mounted. In the case where the air A in the tank 2 is heated, the heating part may have a high output that is not suitable for heating the air A in the tank 2. It is valid.

  Another example of the embodiment shown in FIGS. 14 and 15 is an example in which the tank 2 is provided with a pressure relief valve 33 for preventing the internal pressure from increasing beyond a predetermined level. The pressure relief valve 33 of this example is provided in the top surface 2b portion of the tank 2 where the air A layer is easily formed. According to this, as shown in the graph of FIG. 15, when the pressure relief valve 33 does not exist in the tank 2, the tank 2 internal pressure may increase excessively when the air A in the tank 2 is heated (dotted line graph). In the case where the pressure relief valve 33 exists in the tank 2, when the air A in the tank 2 is heated and the internal pressure of the tank 2 falls to a predetermined pressure, the pressure relief valve 33 opens to set the internal pressure of the tank 2 to a predetermined level. (See the solid line graph). Thus, since the pressure relief valve 33 can prevent an excessive increase in the internal pressure of the tank 2, it is possible to stably supply the stored water W in the tank 2 to the discharge electrode 3 and prevent damage to the tank 2.

  In another example of the embodiment of FIG. 16, the water supply means includes a tank heating unit 34 that heats the air A in the tank 2 exclusively, and the air in the tank 2 heated by the tank heating unit 34 is provided. It is an example provided with the temperature adjustment means which adjusts the temperature of A. In this example, the tank heating section 34 is constituted by a plate heater, and the tank heating section 34 is attached to the bottom surface 2a of the tank 2, that is, the tank heating section 34 is built in the tank 2. However, the tank heating unit 34 is not limited thereto, and may be provided separately from the tank 2, for example, on the bottom surface 18 a of the tank storage unit 18. As the temperature adjusting means, for example, a temperature sensor for measuring the temperature in the tank heating unit 34 or the tank 2 is provided, and the output control of the tank heating unit 34 can be performed based on the detected value of the temperature sensor. As the water supply means, it is conceivable that the air A in the tank 2 is heated by a heat generating part originally provided in various devices on which the electrostatic atomizer 1 is mounted. Compared to this, the water supply means is as described above. By providing the tank heating section 34 for heating the air A in the tank 2 exclusively, the air A in the tank 2 can be efficiently heated, and the tank 2 heated by the tank heating section 34 can be heated. Temperature adjusting means for adjusting the temperature of the air A in the tank 2, the temperature of the air A in the tank 2, and thus the internal pressure due to the expansion of the air A in the tank 2 can be adjusted as appropriate. A temperature management and internal pressure management of A can be stably performed. Therefore, the stable supply of the stored water W in the tank 2 to the discharge electrode 3 can be effectively achieved. More specifically, the water supply means provided with the tank heating unit 34 is also connected to the discharge electrode 3 of the stored water W in the tank 2 in various devices that do not have a heat generating unit capable of heating the air A in the tank 2. There is also an advantage that it is possible to mount the electrostatic atomizer 1 that enables stable supply of the above.

  Another example of the embodiment of FIG. 17 is another example of the storage means described above. The storage means of this example is configured by forming a void-like air reservoir 35 projecting outwardly on one side end of the tank case 20 on the side where the water supply port 24 is provided. In the case of this example, a pair of air reservoirs 35 are provided adjacent to the left and right sides of the water supply port 24. As shown in FIG. 17D, the water supply port 24 that appears when the insertion tube portion 21 is removed from the tank case 20 faces upward, and water is supplied from the outside by pouring water into the water supply port 24 from the outside. When this is done, the air reservoir 35 is in a closed space projecting upward from the side wall which is the upper surface of the tank case 20, so that the water A replenished in the tank case 20 and the air A remains, That is, a certain amount of air A can be left in the tank 2 automatically when water is supplied to the tank 2. The precedent storage means is configured by adding a replenishment mark on the outer surface of the tank 2, and replenishing the water so that the surface of the water replenished in the tank 2 is visually aligned with the replenishment mark. However, the storage means of this example can automatically leave a certain amount of air A in the tank 2 when the tank 2 is replenished with water. This has the advantage that it can be replenished with good workability.

  In the above embodiment, the electrostatic atomizer 1 provided with the counter electrode 4 is described. However, the counter electrode 4 is not always necessary, and it is only necessary to apply a high voltage to the discharge electrode 3 with respect to the ground potential. It is also preferable to employ the electrostatic atomization apparatus 1 in which the electrostatic atomization is performed and the counter electrode 4 does not exist. Moreover, in the said embodiment, although the hair setter 10 was illustrated as an apparatus carrying the electrostatic atomizer 1, the said apparatus is not restricted to this, Barber equipments, such as a hair dryer, and air-conditioning equipment may be sufficient, especially a hair setter. If the electrostatic atomizer 1 of the above embodiment is employed in a barber device such as a hair dryer that may have a state where the atomizing electrode is positioned above the tank 2 in the usage pattern as in the case of the tank 10, the tank By effectively supplying the storage water W in the discharge electrode 3 to the discharge electrode 3, the water supply means that enables stable supply of the storage water W in the tank 2 to the discharge electrode 3 can be effectively exhibited. It is. Further, in the above embodiment, the tank 2 is individually provided with, for example, the overheat prevention means, the pressure relief valve 33, etc., but for convenience of explanation, for example, the overheat prevention means and the pressure relief valve 33 are listed. Needless to say, it is also possible to obtain the effect by combining these other techniques (configurations) such as providing the tank 2 at the same time.
