Description

  The present invention relates to a cosmetic device, and more particularly, to a cosmetic device that gives warm or cold thermal stimulation to a user's skin by steam or mist.

  Conventionally, ultrasonic mist is used to generate mist, and this mist is mixed with steam and it is not hot and contains sufficient moisture, or mist and steam are switched to each other independently on the human skin. 2. Description of the Related Art A cosmetic device that is applied is known (for example, Patent Document 1).

  In addition, in order to refine the steam, a cosmetic device having a steam generator that refines steam by applying a voltage between a pair of discharge needles to generate discharge in the steam path is known (for example, (See Patent Document 2).

  However, in the conventional example shown in Patent Document 2, fine steam particles are obtained by discharge. However, dew condensation water tends to adhere to the surface of the discharge needle having a sharp tip, and in this case, the electric field distribution at the tip of the needle is Disturbed and unstable discharge. In particular, when the tip is covered with condensed water, a significant discharge failure occurs, and there is a problem that miniaturization (ionization) of steam becomes difficult.

Therefore, in generating fine steam, preventing condensation on the surface of the discharge needle is an extremely important issue.
Registered Utility Model No. 3054750 JP 2006-26395 A

  The present invention has been invented in view of the above-described conventional problems, and has a simple structure in which a water absorbent is disposed close to a discharge needle, and can prevent disturbance of an electric field distribution due to condensation, thereby increasing discharge efficiency. An object of the present invention is to provide a cosmetic device capable of improving the efficiency of refinement of steam.

In order to solve the above-mentioned problem, the present invention is a cosmetic device provided with a steam generating mechanism 10 that refines steam generated by heating water supplied from the water supply path 24 and discharges the steam from the steam nozzle 1. The discharge portion 74 is disposed close to the outer periphery other than the pair of discharge needles 31 and 31 'exposed to the steam path 26 through which the steam passes and the distal ends of the discharge needles 31 and 31'. It is characterized by comprising a water absorbing body 70 for absorbing water on the surfaces of 31 and 31 '.

With such a configuration, even if dew condensation water adheres to the surfaces of the discharge needles 31 and 31 ′ due to steam, the dew condensation water is disposed by the water absorbing body 70 disposed close to the outer periphery other than the tip portions of the discharge needles 31 and 31 ′. Since water is absorbed, it is possible to prevent the electric field distribution from being disturbed at the tips of the discharge needles 31 and 31 ′, which are the discharge part 74, and to stabilize the discharge. Accordingly, the discharge efficiency is increased and the steam refinement efficiency can be improved.

In addition, it is preferable that the intermediate electrode 68 is disposed between the distal ends of the pair of discharge needles 31 and 31 ′. In this case, the discharge needle 31 (31 ′ that is on the ground side via the intermediate electrode 68). ), The dielectric breakdown voltage required for the discharge is reduced, so that the discharge can be easily generated even when a low voltage is applied to the discharge needle 31 (31 ′).
In addition, it is preferable to provide a plurality of protrusions 72 on the outer surface of the water absorbent 70 disposed close to the discharge needles 31 and 31 ′. The discharge efficiency is further improved due to the stabilization of the current.

  Further, it is preferable that the water absorbent body 70 is made of a nonwoven fabric, and the fluffy fiber material on the outer surface of the nonwoven fabric constitutes a plurality of protrusions 72. In this case, the electric field is generated by using fraying and fluffing of the fiber material. Since the effect of preventing the disturbance of the distribution can be further enhanced, it is possible to reliably increase the efficiency of refinement of the steam at a low cost by using an inexpensive non-woven fabric.

In the present invention, by disposing a water absorbent close to the outer periphery other than the tip of the discharge needle , disturbance of the electric field distribution due to dew condensation can be prevented, thereby stabilizing the discharge, resulting in increased discharge efficiency and refined steam. It is possible to provide a highly efficient cosmetic device.

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

  FIG. 2 shows an external view of the cosmetic device of the present invention. A nozzle cover 12 to which the steam nozzle 1 and the mist nozzle 2 are attached is provided on the top surface 73 of the main body A of the cosmetic device. The nozzle cover 12 can be rotated at a predetermined angle (for example, 25 to 55 °), whereby the directions of the steam nozzle 1 and the mist nozzle 2 integrated with the nozzle cover 12 can be rotated.

  Here, FIG. 3 shows an example of the arrangement of the steam nozzle 1 and the mist nozzle 2. In the example of FIG. 3, the steam nozzle 1 installed on the nozzle cover 12 is disposed on the left side and the mist nozzle 2 is disposed on the right side when viewed from the treatment direction. In FIG. 3, the mist nozzle 2 is configured so that the stream line S1 of the steam ejected from the steam nozzle 1 installed on the nozzle cover 12 and the stream line M1 of the mist ejected from the mist nozzle 2 intersect at an optimum treatment distance P. Or the angle of the steam nozzle 1 can be adjusted. Further, the angle of both the steam nozzle 1 and the mist nozzle 2 is set so that the steam flow line S2 and the mist stream line M2 are obtained as the optimum treatment distance Q by relatively moving the optimum treatment distance P on the center of the main body A. Adjustable. Further, as shown in FIG. 4, the two nozzles 1 and 2 are not installed in one nozzle cover 12, but the steam nozzle 1 and the mist nozzle 2 are respectively provided on the nozzle covers 12 a and 12 b that are independently adjustable in angle. In this case, since the steam discharge angle and the mist ejection angle can be individually adjusted, the usage application is widened.

  On the front part of the top surface 73 of the main body A, the power button 3, the operation control button 4, and the use course selection button 5 are arranged side by side. The power button 3 is a mechanical switch so that the operation of the main body can be surely stopped even when the main body A runs away. The operation control button 4 has functions of starting and stopping the operation of the main body A. The use course selection button 5 is used to select an arbitrary use course described later. Input signals from the buttons 3 to 5 are sent to a control circuit constituted by a microcomputer.

  A concave tank holder 22 opened upward is provided at the rear part of the top surface 73 of the main body A, and the water supply tank 6 is detachably accommodated in the tank holder 22 in the vertical direction. The water supply tank 6 of the present embodiment is for storing a specified amount (for example, 120 ml) of water, and can be popped upward by a push operation with the main body lid 7 opened. The structure is fixed, and the attachment / detachment operation is facilitated.

  The top surface 73 of the main body A can be freely opened and closed by the main body lid 7. The body lid 7 is rotatably attached by a hinge portion 11 provided on the body A, and is kept in an open position when the cosmetic device is used and in a closed position when stored. In the closed posture, the nozzles 1 and 2, the nozzle cover 12, the various buttons 3 to 5, and the water supply tank 6 are respectively covered. A reed switch (not shown) is built in the hinge portion 11 of the main body lid 7. This reed switch detects the posture of the main body lid 7 and is turned on when the main body lid 7 is in the open position so that the operation control button 4 and the use course selection button 5 can be electrically operated. On the other hand, when the main body lid 7 is closed, the main body lid 7 is turned OFF and functions as a safety switch for stopping all operations of the main body A.

  A carrying handle 8 is attached to the outside of the main body A. In this example, both ends of the handle 8 are attached to the both sides of the housing 13 so as to be pivotable in the vertical direction indicated by the arrow d in FIG. Then, as shown in FIG. 2B, the design is such that the main body lid 7 is obstructed and the handle 8 cannot be rotated upward. As a result, when carrying the handle 8, the handle 8 cannot be rotated to the carryable angle unless the body lid 7 is closed. Stopped by the reed switch, safety is improved. The term “safety” as used herein refers to an accidental contact of steam with a human body during carrying or a burn due to contact with bumping due to the inclination of the main body A or the like.

  An inclination detection switch 15 is installed on the bottom surface of the base 14 of the main body A. When the main body A tilts or floats from a fixed position, the tilt detection switch 15 jumps out and turns on, and at this time, it functions as a safety switch that stops all operations of the main body A. This tilt detection switch 15 is effective for ensuring safety when the main body A falls down during use or when the main body A is carried without using the handle 8 and the main body lid 7 is opened. is there.

  A power cord 9 is wired at the bottom of the main body A. For example, the power cord 9 is sandwiched and fixed between a housing 13 and a base 14, and the base 14 is fixed to the housing 13 with screws.

  Further, as shown in FIG. 7, a drain button 16 and a drain port 17 are provided on the back surface of the main body A, and a drain cover 19 that is rotatably attached to the housing 13 with the rotation fulcrum 18 as a fulcrum is provided. It has been. When the drain cover 19 is open (the state shown in FIG. 7A), the drain cover 19 is designed to include the drain button 16 and the drain port 17.

  As shown in FIG. 8, the drain button 16 of this example is slidably hooked to the drain button cover 56. The drain button cover 56 is screwed and fixed to a drain pipe 57 formed integrally with the drain port 17. The drain pipe 57 is connected to the water supply path 24 described above at the branch portion G. A drainage lever 58 is disposed on the back surface of the drainage button 16 so as to be rotatable at a rotation fulcrum 59 and fixed to the drainage pipe 57. The drain pipe 57 encloses a drain packing 60 formed of an elastic member (for example, silicon). The drainage packing 60 is fixed by an E ring 66 attached to the slide bar 61, and the drainage packing 60 is disposed below the E ring 63 attached to the slide bar 61. The drain pipe 57 is fixed to the tank holder 22 with screws, whereby the drain packing 60 is sandwiched between the members 57 and 22 to seal the seal portion 62. A spring 64 is installed in the upper part of the E ring 63 attached to the slide bar 61 by passing the slide bar 61 through the inner periphery, and the E ring 63 is used as a stopper for the spring 64. That is, the outer shape of the spring 64 is designed to be smaller than the outer shape of the E-ring 63. The stopper above the spring 64 is the tank holder 22. The drainage lever 58 is disposed below the E-ring 63 and is designed to contact the drainage button cover 56 before contacting the drainage packing 60 when rotating downward to prevent the drainage packing 60 from being damaged. The drain button 16 and the drain port 17 are arranged so as to protrude outward from the housing 13.

  Here, before draining, the spring 64 pushes down the E-ring 63 downward. As a result, the slide bar 61 is pushed down, and the E-ring 66 and the drainage packing 60 are also pushed down. As a result, the drainage packing 60 seals the seal portion 62. Therefore, although the branch part G is a path | route filled with water, since the seal part 62 is sealed, water does not flow out from the drain outlet 17. FIG. During drainage, the drainage cover 19 is opened and tilted sideways, and the drainage button 16 is pushed. At this time, the drainage lever 58 rotates and lifts the E-ring 63. As a result, the slide bar 61 slides upward, and the E-ring 66 and the drainage packing 60 also move upward to open the seal portion 62. Here, the branch portion G is disposed at a position lower than the water supply tank 6, the steam generation mechanism 10, and the mist generation mechanism 20, and the drain port 17 is disposed at a position lower than the branch portion G. When the drainage cover is opened and the drainage button is pushed, the remaining water in the main body flows down from the branch part G to the drainage port 17 in the direction indicated by the arrow M in FIG. It flows out of the main body along the back surface 19b having a bowl shape.

  Next, the steam generating mechanism 10 and the mist generating mechanism 20 built in the main body A will be described in order.

  First, the steam generation mechanism 10 will be described. As shown in FIG. 5, the steam generation mechanism 10 includes a steam boiler 23 that heats water supplied from the water supply tank 6 to generate steam, and a discharge unit 74 that refines (ionizes) the generated steam. And a steam nozzle 1 that ejects fine steam.

  In this embodiment, a tank holder 22 for detachably attaching the water supply tank 6 is fixed to the housing 13 with screws, and the tank holder 22 and the steam boiler 23 are formed of an elastic member (for example, silicon rubber). Are connected by a water supply path 24. A steam heater 25 is fixed to the steam boiler 23 with a screw, and a steam path 26 is connected and fixed. A bellows-like elastic member 27 (for example, silicon rubber) is connected to the steam path 26, and a nozzle holder 29 connected to the nozzle packing 28 is connected to the bellows-like elastic member 27. The steam nozzle 1 is connected and fixed to the nozzle packing 28. A boiling chamber 30 is provided at a connection portion of the steam boiler 23 with the steam heater 25, and the water volume is designed to be the minimum volume with the highest vaporization efficiency with respect to the power consumption of the steam heater 25. The steam boiler 23 is fixed to the housing 13 with screws.

  The display circuit 33 equipped with a microcomputer is provided with an operation control button 4, a use course selection button 5, and an LED for notifying the operation state of the main body. The heater thermistor 35 fixed with screws is connected to a water temperature thermistor 36 described later. A steam heater 25, a high voltage circuit 32, a display circuit 33, a power button 3, and a power cord 9 are connected to the power circuit 34. Here, the branch part G of the water supply path 24 is branched into three branches and connected to the mist generating mechanism 20 side and the drain port 17 side.

  Further, a discharge portion 74 is provided in the steam path 26. The discharge unit 74 is provided with discharge needles 31 and 31 ′ connected to the high-voltage circuit 32 so as to face the steam path 26, and the steam is refined by high-pressure discharge from the discharge needles 31 and 31 ′. FIG. 1 shows an example of the arrangement structure of the discharge needles 31, 31 '. An electrode holder 67 is connected to the steam path 26 at a counter electrode position, and the electrode holder 67 is formed integrally with the discharge needles 31, 31 ′ (for example, φ0.5 AgPd material). The discharge needles 31, 31 'are connected to the high voltage circuit 32, the discharge needles 31, 31' are on the high voltage side, and the discharge needles 31, 31 'are on the ground side. An intermediate electrode 68 (for example, φ0.7 Pt material) is installed in the middle of the discharge needles 31 and 31 ′ in a direction perpendicular to the discharge needles 31 and 31 ′, and the intermediate electrode 68 is an intermediate electrode holding member 69 (for example, SUS304). Retained. The intermediate electrode holding member 69 is press-fitted and fixed to the steam path 26. The position of the intermediate electrode 68 is set so that the high-pressure discharge by the discharge needles 31, 31 ′ is performed only through the intermediate electrode 68 without passing through the intermediate electrode holding member 69.

  In the operation mode of the steam generating mechanism 10, the water supplied from the water supply tank 6 is supplied to the steam boiler 23 through the water supply path 24 and is stabilized at a constant water level W. When the steam heater 25 is turned on, the water in the boiling chamber 30 is heated and vaporized, and becomes steam from the upper part of the boiling chamber 30 and is ejected from the steam nozzle 1 through the steam path 26. When passing through the steam path 26, the steam is refined (ionized) by receiving a high-pressure discharge by the discharge needles 31, 31 '. In addition, by designing the boiling chamber 30 to have a minimum volume with good vaporization efficiency, a small amount of water can be heated, the steam generation start time is shortened, and the steam generation waiting time of the human body can be shortened. When the water in the boiling chamber 30 decreases and the water level decreases due to the steaming, water supply from the water supply tank 6 is started to try to stabilize at the water level W, and steam is ejected while repeating this. When the water in the water supply tank 6 runs out and the water level in the boiling chamber 30 continues to decrease, the temperature of the steam heater 25 rises. When the set temperature is exceeded, the heater thermistor 35 detects this and turns off the steam heater 25. In other words, it is designed to ensure safety against ignition, smoke, etc. by preventing air blow. Further, when water is supplied excessively using a water tank other than the water supply tank 6, it overflows from the overflow hole 54 of the tank holder 22 and is drained to the drainage path 80 connecting the drainage port 17 and the overflow hole 54. The overflow hole 54 is installed at a position where bumping in the boiling chamber 30 does not jump out of the steam nozzle 1 and is designed so as not to raise the water level in the boiling chamber 30 to a dangerous area.

  Next, the mist generating mechanism 20 will be described. In the mist generating mechanism 20, a water supply path 24 formed of an elastic member connected to the aforementioned branching part G is connected to a heating part 37. A mist heater 38 is fixed to the heating unit 37 with a screw and includes a damper 39. The damper 39 is provided with an inlet 40 on the lower side and an outlet 41 on the upper side, and the space between the two 40 and 41 is divided into, for example, four layers by a plate-like lattice material 42. Here, it is preferable to divide into several layers by the lattice material 42 so that the path length from the inlet 40 to the outlet 41 is the longest. However, if the distance between the lattice members 42 is too small, the path resistance increases, so that the mist The amount decreases, which is not preferable. Even if the distance between the lattice members 42 is kept at an optimum value and the number of layers is increased too much, it takes time to achieve the sterilization conditions (for example, 80 ° C./30 seconds or more) by increasing the water volume of the damper 39. End up. Therefore, after designing the water volume of the damper 39 that can efficiently achieve the sterilization condition with respect to the power consumption of the mist heater 38, the layer is formed while keeping the distance between the lattice members 42 at the optimum value. A water temperature thermistor 36 is installed at the inlet 40 of the damper 39 so that its temperature measuring part is located in the damper 39. Moreover, the area of the inflow port 40 is formed with the minimum area which does not impair the inflow property of water. The outlet 39 of the damper 39 is connected to the liquid supply path 43, and the liquid supply path 43 communicates with the mist nozzle 2 that is hooked to the nozzle holder 29 through the heat radiating member 44 (for example, aluminum fin). The nozzle holder 29 is formed integrally with the nozzle holder 29 described in the steam generation mechanism 10. A gas-liquid exchange chamber 45 is installed between the heat radiating member 44 and the outlet 41. The gas-liquid exchange chamber 45 is preferably cylindrical and has a central axis installed in the horizontal direction. An air delivery path 47 connected to the pump 46 is connected to the mist nozzle 2. Here, the motor 49 (air blowing part) to which the blower fan 48 is attached is installed on the windward side, the heat radiating member 44 is installed on the leeward side, and the air supply path 50 including each is installed. Further, the discharge port 51 for discharging the blast of the blast supply passage 50 is installed coaxially with the mist nozzle 2. A filter 52 is attached to the suction port of the air supply path 50, and the filter 52 is installed on the bottom surface of the base 14. On the other hand, a pressure release port 53 is provided on the upper surface of the heating unit 37 (preferably above the water level W) and connected to the tank holder 22 at a position above the water level W. The mist heater 38, the pump 46, and the motor 49 are connected to the power supply circuit 34 (FIG. 5).

  In the operation mode of the mist generating mechanism 20, when water is supplied to the heating unit 37 by the water supply path 24, the water flows into the damper 39 from the inlet 40 through the path divided by the lattice material 42, and the water level W It stabilizes at. Simultaneously with the start of the main body operation, the mist heater 38 is turned on to heat the water in the heating unit 37 including the damper 39. The water temperature in the damper 39 is detected by the water temperature thermistor 36, and the operation of turning off the mist heater 38 when the temperature becomes higher than a specified temperature (for example, 80 ° C.) and turning it on when the temperature becomes lower is repeated. The water temperature thermistor 36 is preferably installed at a place where the water temperature in the damper 39 is the lowest. In the example of FIG. When the water temperature of the heating unit 37 starts to rise, the water in the heating unit 37 causes convection. However, since the convection of the water in the damper 39 is suppressed to the minimum by the lattice material 42, the water warmed in the damper 39 does not go out of the damper 39, and a stable water temperature rise can be obtained. In addition, for the water convected outside the damper 39 and the water newly supplied from the water supply path 24, the area of the inlet 40 of the damper 39 is minimized, and the water in the damper 39 is difficult to move. It becomes difficult to flow into the damper 39. The specified temperature (for example, 80 ° C.) is set from the sterilization conditions. For example, in the case of Legionella bacteria or the like, the structure of the heating unit 37 of this embodiment takes into account the safety factor, and if the water temperature of 80 ° C. continues for 30 seconds or more, the mortality rate of the bacteria becomes 100%. That is, this is the sterilization condition. If the specified temperature is set high, the required heating time can be shortened, but the water in the heating unit 37 boils, and steam is ejected from the mist nozzle 2 or the hot water in the heating unit 37 flows back to the tank holder 22. This is undesirable because it causes an unsafe phenomenon.

  Moreover, in this cosmetic device, there is no use course only for mist, and the start of driving always generates steam for several minutes (for example, 5 minutes). During this period, sterilization conditions are achieved and the operation shifts to mist operation. Therefore, it is necessary to set the initial steam generation time to a time at which the sterilization conditions can be achieved. When the sterilization conditions are achieved, the pump 46 and the motor 49 can be driven. When the pump 46 is turned on, the air ejected from the pump 46 is ejected from the mist nozzle 2 through the delivery path 47. The mist nozzle 2 designed to generate the Venturi effect sucks hot water in the damper 39 through the liquid supply path 43 and ejects it as mist. Furthermore, dissolved oxygen in the water is generated as bubbles in the damper 39 by heating the water in the damper 39. In addition, bubbles are also mixed when water is sucked up by the mist nozzle 2 due to a step in the inner wall of the liquid supply path 43. The bubbles generated thereby divide the water in the liquid supply path 43. The sucked bubbles enter the gas-liquid exchange chamber 45 filled with water and move upward to be captured and exchanged with water. Therefore, the liquid supply path 43 after passing through the gas-liquid exchange chamber 45 does not contain bubbles. The volume of the gas-liquid exchange chamber 45 is designed to be larger than the generated air. Here, it is preferable to drive at a low speed for several seconds (for example, 1 second) when the pump 46 is ON. As a result, the sucked water suddenly flows into the gas-liquid exchange chamber 45 and the mist operation is not started while leaving the air in the gas-liquid exchange chamber 45. That is, by slowly allowing the sucked-up water to flow into the gas-liquid exchange chamber 45, all of the light air having a low specific gravity can be ejected from the mist nozzle 2 first, and the gas-liquid exchange chamber 45 is filled with water. After low speed driving, shift to normal driving. When the motor 49 is turned on, the blower fan 48 rotates and takes in air outside the main body A through the filter 52. The taken-in air is discharged from the discharge port 51 through the air supply path 50. At this time, the heat radiating member 44 included in the air supply path 50 is air-cooled, and the hot water temperature in the liquid supply path 43 is lowered. Thereby, the mist temperature ejected from the mist nozzle 2 is lowered and the cooling feeling is improved. Further, when the air discharged from the discharge port 51 hits the skin of the human body, the heat of vaporization of moisture by the mist adhering to the skin can be taken away, and the cooling feeling can be further improved. Further, the filter 52 is designed to have an opening efficiency or a mesh roughness so that dust or the like is not mixed into the air supply path 50.

  Next, an operation process from the start to the end of use of the cosmetic device will be described.

  With the main body lid 7 open, the power cord 9 is inserted into a commercial outlet and power is supplied to the beauty device. Thereafter, the power button 3 is pressed to bring the main body A into an operable state. In other words, when the main body lid 7 is opened, the reed switch built in the hinge 11 detects the posture of the main body lid 7 and is turned on, whereby the operation control button 4 and the use course selection button 5 can be operated. Become. Thereafter, the use course selection button 5 is pressed to select a desired course. The use course selection button 5 is set so that the use course is sequentially switched every time the button is pressed. Here, the course of use is the one in which the temperature generated by steam and the time of occurrence of cooling by mist and the number of repetitions are set so that the effect on the skin is optimal. For example, the temperature and temperature are not given to the skin at the same time. It is set so as to be given alternately in order to emphasize skin irritation caused by the difference. It is also possible to give steam and mist at the same time to obtain other effects. When an arbitrary use course is determined, when the operation control button 4 is pressed, the operation of the main body A starts and the selected use course is executed.

  For example, when a course of use in which temperature and cold are alternately selected is selected, only the steam generation mechanism 10 is driven first, and steam is ejected from the steam nozzle 1 after a specified time has elapsed to give warmth to the human skin. . When the specified time further elapses, the steam stops, the pump of the mist generating mechanism 20 is driven, mist is ejected from the mist nozzle 2, and the human skin is cooled. Further, when the specified time elapses, the mist stops and steam is generated again. This operation is automatically completed for the set number of times and time repetition operation. It is designed so that the operation can be ended by pressing the operation control button 4 or the power button 3 during use.

  When the body lid 7 is closed after use, the reed switch is turned off, and all operations of the body A are disabled.

  When draining after the operation is finished, the drain cover 19 is opened and the drain button 16 is pushed to drain the remaining water from the drain port 17. Since the drain button is enclosed by the drain cover when the drain cover 19 is closed, the drain button 16 cannot be pushed unless the drain cover is opened. Therefore, it can be used comfortably and safely. Moreover, when the drainage cover is opened, the back surface 19b of the drainage cover 19 has a bowl shape that can drain the drainage from the drainage port 17 to the outside of the main body A. Therefore, the drainage cover functions as a drainage rail. The streamline direction of the drainage can be stabilized, whereby hot water can be prevented from coming into contact with fingers and the like, and a safe hot water drainage effect can be obtained. Here, in order to prevent a gap from being formed between the drain port 17 and the one end 19a of the drain cover, one end 19a of the drain cover 19 is an overlap portion 21 with the drain port 17, It is possible to prevent drainage leakage from the gap S between the one end 19a of the drainage cover 19 and the drainage port 17, and the safety is further improved.

  Here, in the present invention, as shown in FIG. 1, a fiber (for example, non-woven fabric) is coaxially installed as a water absorbent 70 over the entire circumference of the discharge needles 31 and 31 ', and this water absorbent is provided. An insulator 71 (for example, silicon rubber or Teflon (registered trademark)) is installed so as to enclose the body 70 and the electrode holder 67. Here, the discharge needles 31, 31 ′ protrude from the water absorption body 70 by 0.5 to 1.0 mm to prevent the discharge needles 31, 31 ′ from being completely buried in the water absorption body 70, and the other discharge needles 31, 31. It is preferable that the entire circumference is covered with the water absorbing body 70. The arrows indicate the flow of steam, Y indicates the steam boiler 23 side, and Z indicates the steam nozzle 1 side.

  In the steam path 26 in which steam flows from the steam boiler 23 toward the steam nozzle 1, discharge starts from the discharge needles 31, 31 ′ on the high-pressure side, and the discharge needle 31, which is the ground side via the intermediate electrode 68, Discharge to 31 '. At this time, if condensed water adheres to the tips of the discharge needles 31 and 31 'where the ion generation electric field is concentrated, the ion generation efficiency is extremely hindered. Therefore, the present invention has a structure in which disturbance of the electric field distribution can be prevented by absorbing dew condensation due to steam adhering to the discharge needles 31 and 31 ′ by the water absorbent body 70 made of nonwoven fabric.

  Therefore, in this cosmetic device, even if condensed water adheres to the surfaces of the discharge needles 31 and 31 ′ due to steam, the condensed water is absorbed by the water absorbing body 70 disposed close to the discharge needles 31 and 31 ′. Disturbance of the electric field distribution at the tips of the discharge needles 31 and 31 ′, which are the discharge part 74, can be prevented and the discharge is stabilized. Accordingly, the discharge efficiency is increased and the steam refinement efficiency is improved.

  Further, in this example, the water absorbent 70 is made of a non-woven fabric, and the fluff-like fiber that protrudes from the outer surface of the non-woven fabric is a plurality of protrusions 72. The discharge efficiency is further improved due to the stabilization of the current. In other words, it is possible to further enhance the effect of preventing disturbance of the electric field distribution by using fraying and fluffing of the fiber, and by using an inexpensive non-woven fabric, it is possible to reliably increase the efficiency of refinement of the steam at a low cost. Is.

  Further, in this example, since the structure in which the discharge needles 31 and 31 ′ on the ground side are discharged via the intermediate electrode 68 is adopted, the dielectric breakdown voltage required for the discharge is lowered, so that a low voltage is applied to the discharge needle 31. There is also an advantage that a discharge can be easily generated even when applied. The intermediate electrode 68 can be omitted.
