As a simple configuration, the distance X, that is, the distance between the infrared sensor and the head, may be used as the distance between the discharge port 5 and the head without subtracting the distance Y from the distance X.

  FIG. 6 is a block diagram schematically showing an electrical configuration of the scalp care device 1 of the present embodiment. As shown in FIG. 6, the control board 24 built in the handle portion 23 has a motor 17 of the blowing means 15, a heating means 21, and a high voltage generating section 11 of the metal fine particle forming means 2 correspondingly controlled. A control unit, that is, an air amount control unit 20, a heat amount control unit 22, and a discharge control unit 25 are provided. A power supply unit 8 is connected to the control board 24, and the power supply unit 8 supplies power to each of the control units 20, 22, and 25. These control units 20, 22, 25 are controlled by controlling the supply power based on the signals S1, S2 input from the switch 7 and distance detection means 19 provided in the handle unit 23, that is, It is configured to optimally control the amount of air blown by the blower 15, the amount of heat applied by the heating means 21, and the voltage applied to the electrode 12 by the high voltage generator 11.

  FIG. 7 is a flowchart schematically showing the operation of the scalp care device 1 of the present embodiment. When the user turns on the switch 7 (S1), a signal S1 is output from the switch 7, and the signal S1 is input to the air amount control unit 20, the heat amount control unit 22, and the discharge control unit 25, and each control unit 20, 22, and 25 start supplying power to the respective controlled objects (S 2).

  Next, the distance detecting means 19 detects the distance between the discharge port 5 and the head (S3), compares the detected distance with a preset threshold value (S4), and the detected distance is larger than the threshold value. In this case, the air amount control unit 20 increases the amount of air blown by the blowing unit 15, and the heat amount control unit 22 increases the amount of heat applied by the heating unit 21 (S5). Here, as shown in FIG. 8, the amount of air blown by the blowing means 15 is determined as a minimum amount of air flow and a maximum amount of air blown, and is sent as the detection distance increases between the minimum and maximum air flow rates. The air volume is controlled to be large. As shown in FIG. 9, the amount of heat applied by the heating means 21 has a minimum heating amount and a maximum heating amount. When the detection distance increases between the minimum and maximum heating amounts, the heating amount increases stepwise. To be controlled. In FIG. 9, the heating amount is changed in one step, but may be changed in a plurality of steps. In S4, when the threshold value and the detection distance are equal, the air amount control unit 20 and the heat amount control unit 22 maintain the current control (S6).

That is, when the detection distance is smaller than the predetermined threshold, the amount of heat applied from the heating means 21 can be reduced to reduce damage to the scalp and hair by hot air, and the fine particle generator 9 is heated by hot air. Can be prevented from deteriorating. Further, since the amount of air blown by the blowing means 15 is reduced, energy saving can be achieved. On the contrary, when the detection distance is larger than the predetermined threshold, the amount of air blown by the blowing means 15 increases, so that the metal fine particles can be reliably supplied to the scalp together with the air, and the hair is scraped off by the blowing. Therefore, the metal fine particles can be stably supplied to the scalp.

  Next, a fourth embodiment will be described based on FIG. In addition, about the structure similar to the scalp care apparatus 1 of 3rd Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

FIG. 12 is a flowchart schematically showing the operation of the scalp care device 1 of the present embodiment.
When the user turns on the switch 7 (S11), it is determined whether or not the discharge control unit 25 receives the signal S3 from the contact switch 26, that is, whether or not the contact switch 26 detects contact. (S12). If contact is detected, the discharge controller 25 supplies power to the high voltage controller 11 and applies a voltage to the electrode 12 to form a discharge to generate metal particles (S13). On the other hand, if no contact is detected, the process proceeds to S14.

  If the state of the switch 7 is detected in S14 and the switch is OFF, the series of processing is terminated. If the switch is ON, the processing returns to S12 and the above processing is repeated.
