Description

  The present invention relates to a mist generator capable of discharging a charged fine particle liquid by electrostatic atomization, and a beauty device including the mist generator.

  Conventionally, a mist generator is used as a device for beauty effects such as moisturizing skin and skin care by releasing steam vaporized by boiling a liquid in a boiler toward the face of the human body. (For example, Patent Document 1).

  In the mist generating device described in Patent Document 1, a discharge electrode and a counter electrode are provided in the middle of a steam flow path for discharging steam generated by a boiler to the outside of the device. And in this mist generator, an arc discharge is caused between both electrodes by applying a high voltage between a discharge electrode and a counter electrode. As a result, fine atomized steam is generated by inducing electrostatic atomization to water condensed on the surface of the discharge electrode.

Next, the electrical configuration of the cosmetic device 10 of the present embodiment will be described with reference to FIG.
As shown in FIG. 3, the beauty machine 10 of the present embodiment controls a discharge circuit 34 and a warm mist heater 26 based on a power supply circuit 39 connected to a power cord 38 and power supply from the power supply circuit 39. And a control board 33 as a control device. The power supply circuit 39 and the warm mist heater 26 (enclosure plate 29) are connected by a first conductive path 51 for supplying power from the power supply circuit 39 to the warm mist heater 26. What is the first conductive path 51? Another second conductive path 52 is also connected. The power supply circuit 39 and the discharge unit 34 are connected by a third conductive path 53 that supplies power from the power supply circuit 39 to the discharge unit 34. A part of the second conductive path 52 is constituted by the conductive wire 32 described above.

  The control board 33 includes a control circuit 40 that executes various arithmetic processes for controlling the discharge unit 34 and the warm mist heater 26, and a filter circuit 41 that is interposed between the control circuit 40 and the power supply circuit 39. Have. The filter circuit 41 is configured by combining a coil, a capacitor, and the like, and is provided in the middle of the second conductive path 52 together with the control circuit 40 so as to be closer to the power supply circuit 39 than the control circuit 40. The filter circuit 41 restricts the noise generated in the control circuit 40 from affecting the peripheral device by being released from the control circuit 40 to the power supply through the power supply circuit 39. The filter circuit 41 also regulates that the noise propagated from the power supply to the power supply circuit 39 through the power cord 38 is affected by the propagation of the noise from the power supply circuit 39 to the control circuit 40. In the present embodiment, the conductive wire 32 is connected to the control circuit 40 of the control board 33 at the end opposite to the connection portion to the surrounding plate 29.

  The control board 33 transmits a control signal from the control circuit 40 to the high voltage generation unit 43 to cause the high voltage generation unit 43 to generate a high voltage for causing arc discharge in the discharge unit 34. The generated high voltage is applied to the discharge needle 36. In addition, the control board 33 adjusts the magnitude of the voltage supplied from the power supply to the PTC element 28 through the power supply circuit 39 by transmitting a control signal from the control circuit 40 to the warm mist heater 26.

Next, the operation of the cosmetic device 10 configured as described above will be described.
In the present embodiment, when an arc discharge is induced from the discharge needle 36 to the counterpart electrode 37 in the discharge unit 34, discharge noise is generated in the discharge unit 34. Then, a part of the discharge noise radiated from the discharge unit 34 is propagated to the enclosure plate 29 or discharged from the discharge unit 34 to the enclosure plate 29 using the warm mist flowing in the warm mist induction unit 35 as a medium. Noise can be propagated. In particular, when the discharge unit 34 and the warm mist heater 26 are arranged close to each other, the discharge noise radiated from the discharge unit 34 is easily propagated to the warm mist heater 26.

  In this regard, in this embodiment, the surrounding plate 29 is connected to the control circuit 40 via the conductive wire 32, and the control circuit 40 is connected to the power supply circuit 39 via the filter circuit 41. Therefore, even if the discharge noise generated in the discharge unit 34 propagates to the surrounding plate 29, such discharge noise propagates to the control circuit 40 through the conductive wire 32 and then propagates from the control circuit 40 to the power supply circuit 39. It is attenuated by the filter circuit 41. Therefore, even if the discharge noise propagates from the discharge unit 34 to the enclosure plate 29, the discharge noise is suppressed from being released to the outside through the power source.

Therefore, the propagation of discharge noise from the warm mist heater 26 to the power source is suppressed. In other words, even if the warm mist heater 26 and the power supply are arranged close to each other, the discharge noise propagated to the warm mist heater 26 is suppressed from being propagated to the power supply. Therefore, it is possible to reduce discharge noise emitted to the outside through the power supply while suppressing an increase in size of the apparatus.

  (2) The filter circuit 41 provided on the control board 33 not only suppresses noise generated in the control circuit 40 from being released to the power supply but also releases noise generated in the warm mist heater 26 to the power supply. It also plays a role of suppressing Therefore, it is not necessary to newly provide a member for suppressing the noise generated in the warm mist heater 26 from being released to the power supply, which can contribute to a reduction in the number of parts.

  (3) In the warm mist heater 26, a surrounding plate 29 arranged so as to surround the PTC element 28 is connected to the control circuit 40 through the conductive wire 32. Therefore, even if discharge noise propagates from the discharge unit 34 to the enclosure plate 29, such discharge noise is attenuated by the filter circuit 41 when propagating to the power supply circuit 39 through the conductive wire 32. Therefore, it can suppress that the discharge noise propagated to the surrounding board 29 is propagated with respect to a power supply.

Therefore, even if discharge noise propagates from the discharge part 34 to the enclosure plate 29, it is avoided that such discharge noise is emitted to the outside through the power source.

  Similarly, the enclosure plate 29 is also connected to the control circuit 40 via the filter circuit 41. Therefore, the discharge noise propagated from the discharge unit 34 to the enclosure plate 29 is attenuated by the filter circuit 41 when propagating from the enclosure plate 29 to the control circuit 40 through the conductive wire 32. Therefore, even if the discharge noise propagates from the discharge unit 34 to the enclosure plate 29, the propagation of such discharge noise to the control circuit 40 is suppressed.
