  The steam generating unit 31 constituting the mist generating device is provided on the front side of the facial beauty body 12 and generates steam (warm mist). The steam generator 31 is provided with PTC (Positive Temperature Coefficient) heaters 35 and 36 on the front side and the rear side that generate heat based on the supply of drive current and have a self-control function of the heat generation. The water supplied into the boiler chamber 37 inside the PTC heaters 35 and 36 is boiled through the steam to generate steam. Incidentally, a part of the water supply pipe 19 extending from the water supply tank 18 is disposed in contact with the outer surface of the front PTC heater 35, and is warmed before flowing into the boiler chamber 37. Steam is generated efficiently within the system. The water supply line 19 is connected to a drain outlet 38a of the facial device 10 via a drain pipe 38 (see FIG. 6), and is a water stop valve on the drain pipe 38 controlled by the operation of a drain switch.

Therefore, the steam generated in the boiler chamber 37 is separated from the branch portion 42 and guided to the steam nozzles 21a and 21b through the first guide pipe 41a and the second guide pipe 41b. Since the pressure in the boiler chamber 37 and the steam guide pipe 41 is high, steam is discharged from the discharge holes of the steam nozzles 21a and 21b with a certain degree of momentum.

A part of the water supply conduit 51 is arranged to meander in the plane direction of the heat radiating surface (vertical surface) 36a of the rear PTC heater 36 and abut against the heat radiating surface 36a. Sterilization of water for cold mist in the water supply pipe 51 is also performed by heating the PTC heater 36 on the side. A filter 52 is mounted in the pipe at a position immediately before the mist nozzle 22 in the water supply pipe 51 to remove dust from the passing water.

  Also, as the mist generating unit 32, a pneumatic feeding path 53 is provided in the facial body 12 and air is fed into the pneumatic feeding path 53 by the operation of a pump 54 using an electric motor as a drive source. Is called. This pumped air is supplied toward the discharge hole of the mist nozzle 22, and a venturi effect is produced by joining the water in the water supply pipe 51 before the discharge hole, and the water in the water supply pipe 51 is sucked out together with the pumped air. As a result, cold mist is generated and discharged.

  The negative ion production | generation part 33 is provided in the nozzle part 13 as shown in FIG.2 and FIG.4, generates a corona discharge, and produces | generates a negative ion. The ion generation unit 33 is configured such that a unitized negative ion discharge unit 61 is accommodated and held in an accommodation recess 23 a formed in the ion nozzle 23 of the nozzle unit 13. In the ion discharge portion 61, the needle electrode 63 is supported with respect to the electrode holder 62 having a predetermined shape so as to be accommodated and held in the accommodation recess 23a, and on the axis of the needle electrode 63 on the distal end side of the needle electrode 63. An annular counter electrode 64 is supported and configured so that the annular center is located. The needle electrode 63 and the counter electrode 64 are each connected to a control circuit board 71 in the vicinity of the upper surface of the facial body 12 through a lead wire 65 connected thereto and led out from the electrode holder 62.

  Incidentally, in this ion generation part 33 (ion discharge part 61), the space X2 around the needle electrode 63 is only opened to the outside, and the space X2 around the needle electrode 63 and the space X1 in the facial body 12 are partitioned. It has been. This is because, when a member using a silicon material (for example, a part of the water supply conduit 51) provided in the space X1 in the face body 12 is heated by a heat source such as the PTC heaters 35 and 36, the space X1 This is because if silicon floats and the floating silicon adheres to the needle electrode 63, corona discharge is hindered and the amount of negative ions generated is reduced, and adhesion of the floating silicon to the needle electrode 63 is prevented in advance. Yes.

  The control circuit board 71 is supplied with power from the outside by a power cord 70 (see FIG. 1), and based on the control of the control circuit 72 composed of various circuit components mounted on the board 71, the steam generation unit 31, Operation power is supplied to each of the mist generation unit 32 and the ion generation unit 33. As shown in FIG. 5, the control circuit 72 switches between the operable state and the stopped state of the facial device 10 based on the on / off operation of the power switch 25, and the operation control switch 26 and the course selection switch in the operable state. Based on the setting of various use courses by 27 combination operations, the operation of the steam generating unit 31 (PTC heaters 35, 36, the steam discharge unit 43, etc.) and the mist generating unit 32 (pump 54, etc.) is controlled. In addition, the ion generation unit 33 (ion discharge unit 61) is operated together with the operations of the previous generation units 31 and 32. Therefore, the beauty effect by a negative ion and steam (warm mist) and the beauty effect by a negative ion and mist (cold mist) can be acquired.

  When a high voltage is applied to the needle electrode 63 during negative ion generation, a corona discharge is generated around the tip of the needle electrode 63 due to a potential difference with the counter electrode 64, and negative ions are generated. The generated negative ions are attracted to the counter electrode 64 having a potential lower than that of the needle electrode 63 and are discharged to the outside from the ion nozzle 23.
