Moreover, it is preferable that the said control part cancels | releases the said alerting | reporting by the said display part in response to the detection output that the cover part was mounted | worn to the main-body part.

In the present invention, the drive part of the main body part does not operate when the cover part is removed, and the drive part stops even if the cover part comes off during scalp massage. Can be high. In addition, it is possible to recognize whether or not the cover portion is attached by the drive control control portion, although the power supply to the drive portion is cut off when the cover portion is removed.

  An example of the embodiment of the present invention will be described based on the illustrated example. This scalp care device is composed of a main body 1 and a rectangular bottom surface of the main body 1 as shown in FIGS. It consists of the cover part 2 attached detachably.

  As shown in FIGS. 1 and 2, the main body 1 includes a motor 3 and a reduction gear train 16 and a secondary battery (not shown) as a power source. These are mounted on a frame 15. It is stored in the main body part 1 in the state of being. The bottom of the main body 1 is watertightly closed by a bottom plate 18, and four drive shafts project downward through the bottom plate 18, and an eccentric pin 17 is attached to each drive shaft. In the figure, reference numeral 35 denotes a charging connector.

  A head portion 11 larger than the neck portion 10 is provided on the upper portion of the main body portion 1 through a neck portion 10. The head portion 11 includes a mode switching switch 13, a light emitting diode, and a light guide. Three display portions 14a, 14b, and 14c are provided.

  As shown in FIG. 3, the cover portion 2 connected to the bottom portion of the main body portion 1 is a cover 21 made of a soft resin that is thin and flexible on the lower outer surface and outer peripheral surface of the substrate 20 made of hard resin. A plurality of treatment elements 4 for scalp massage are integrally formed on the cover 21 (four in the illustrated example).

  As shown in FIG. 4, each treatment element 4 in the illustrated example is composed of four protrusions, and is integrally provided with a cylindrical portion 23 on the back side (main body 1 side). Furthermore, the inner side of each cylindrical portion 23 has a mortar shape and is provided with an engagement hole for engaging the eccentric pin 17 at the center.

  A four-step slit 28 is formed on the side surface of the guide column 27 provided in the center on the back side of the substrate 20, and any one of the four-step grooves formed on the outer peripheral surface of the cylindrical portion 23 is formed. The other end of the metal guide plate 26 with one end connected is slidably inserted into the slit 28. Note that the four guide plates 26 connected to each cylindrical portion 23 are connected to different step grooves of each cylindrical portion 23 and inserted into slits 28 of different steps. For this reason, when the surgical element 4 including the cylindrical portion 23 performs the movement described later, the guide plates 26 also move simultaneously, but the guide plates 26 do not interfere with each other in the guide column 27.

  The cover portion 2 is detachably connected to the main body portion 1 by engaging hooks 33 provided at the respective centers of the four outer sides of the substrate 4 with the main body portion 1. At this time, the shape of the bottom surface of the main body portion 1 and the planar shape of the cover portion 2 are squares with four corners rounded, and therefore the attachment of the cover portion 2 to the main body portion 1 has no directivity. Yes.

  And when attaching the cover part 2 to the main-body part 1, the four eccentric pins 17 in the main-body part 1 are guided by the mortar-shaped inner surface of the cylindrical part 23, and engage with the treatment element 4, and the eccentric pin 17 carries out eccentric rotation. When performing, each surgical element 4 moves with the eccentric pin 17 in different directions and phases as shown in FIG. In addition, since each treatment element 4 in the cover 21 made of a soft resin has a bellows-like periphery, different movements of each treatment element 4 are smoothly performed. Further, although the protrusions and the cylindrical portion 23 constituting the surgical element 4 are integrally provided on the cover 21 made of a soft resin, the protrusions and the cylindrical portion 23 are formed thick so that they have elasticity necessary for scalp massage. It has become what.

  When using this scalp care device, the neck portion 10 of the main body portion 1 is sandwiched between the index finger and the middle finger so as to wrap the main body portion 1 and the switch 13 is operated. By depressing the switch 13, the motor 3 is sequentially switched between an off state, a low-speed rotation state, and a high-speed rotation state. In the low-speed rotation state, the display unit 14b is turned on as shown in FIG. The display unit 14a is turned on in the high speed rotation state, and the display units 14a, 14b, and 14c are turned off in the off state. The display unit 14c is for displaying charging.

  When the motor 3 rotates, each eccentric pin 17 rotates eccentrically as described above, and each treatment element 4 in the cover portion 2 is driven by the eccentric pin 17 to perform the above-described movement. For this reason, if the treatment element 4 is brought into contact with the scalp, the scalp is massaged by a plurality of treatment elements 4 that approach or separate from each other.

  In this scalp care device, the motor 3 does not rotate even when the switch 13 is operated in a state where the cover portion 2 is not attached to the main body portion 1, and the cover is removed from the main body portion 1 while the motor 3 is rotating. When the part 2 is removed, the motor 3 is stopped immediately, and the reason why the motor 3 does not rotate is that the cover part 2 is not attached to show that FIG. As shown in b), the display unit 14b is caused to blink. However, this blinking is extinguished when a predetermined time (for example, 4 minutes) elapses or when the cover portion 2 is attached. Further, the operation of the switch 13 cancels blinking and turns off the light. Furthermore, even if the cover unit 2 is mounted while the display unit 14b is blinking, the motor 3 is not immediately rotated, but the motor 3 is kept off.

  Here, as shown in FIG. 6, a switching element T for driving the motor 3 and the motor 3 are used as a blocking unit that blocks power supply to the motor 3 depending on whether or not the cover unit 2 is attached to the main body 1. A contact portion SW provided in the middle of the connecting power supply line is opened and closed with a pin 31 shown in FIGS. That is, a power line connecting the switching element T and the motor 3 is formed with a lead plate, a normally open contact portion SW is provided in the middle of the lead plate, and the pin provided on the body portion 1 is provided on the cover portion 2. An interlocking protrusion 25 that presses 31 is provided. Note that a total of four interlocking protrusions 25 are provided in order to eliminate the direction of attachment of the cover 2 to the main body 1.

  When the cover portion 2 is mounted on the main body portion 1, the pin 31 pushed against the spring bias by the projection 25 of the cover portion 2 closes the contact portion SW. However, since the contact SW is open when the cover 21 is removed, no power is supplied to the motor 3, and the motor 3 does not rotate.

  Using the contact part SW for opening and closing the power supply line leading to the motor 3 does not require a switch arrangement space as compared with the case where the attachment / non-attachment of the cover part 2 is detected by a tact switch or the like. The rotation stop control is not required, and there is no possibility of malfunction due to noise or the like, so that the motor can be stopped reliably, and the reliability and safety can be improved. PW in FIG. 6 is a power unit using the secondary battery as a power source.

  However, when the cover part 2 is removed, the power supply to the motor 3 is cut off by the contact part SW from the point of detecting that the cover part 2 is removed and blinking the display part 14b. For example, the control unit C recognizes whether or not the cover unit 2 is mounted by directly receiving the opening / closing signal of the contact unit SW by the control unit C for driving control of the motor 3 and the display unit 14 (14a, 14b, 14c). It means you can't.

  For this reason, the detection of the mounting state of the cover part 2 is performed as follows. That is, as the drive control of the motor 3, one that inputs a pulsed voltage to the motor 3, one that inputs a wavy sine wave, one that inputs a DC power supply voltage whose voltage value changes can be used. Even when the cover portion 2 is not attached, power supply in a range where the motor 3 does not rotate is performed by duty control, and further, the power supply state to the motor 3 is monitored to the main body portion 1 of the cover portion 2. Detecting the wearing.

  As an example, FIG. 8 shows an example in which a pulse voltage is input to the motor 3 by PWM duty control. When the cover unit 2 is attached and normal motor driving is performed, PWM duty control of 30 to 90% is performed to make the motor voltage constant as shown in FIG. When the motor 3 is not mounted, duty control is performed in a range where the motor 3 does not rotate. For example, as shown in FIG. 8B, PWM (pulse wave) is generated (approximately 12% duty) for a fixed time (50 ms) every fixed cycle (300 ms).

  Then, the control unit C checks whether the PWM (pulse wave) is applied to the motor 3 through the peak hold circuit PH shown in FIG. 6 so that the contact unit SW is closed or opened (the cover unit). 2 is attached). Whether or not the cover unit 2 has been attached from the state in which the cover unit 2 is removed is determined when the control unit C detects the cover detection signal three times continuously as shown in FIG. 8 (c). It is determined that it is attached.

  Even if the control unit C detects that the cover unit 2 is attached after the motor unit 3 is stopped after the cover unit is removed while the motor 3 is being driven, as described above, Without immediately restarting the power supply, the motor 3 is kept off until the switch 13 is operated. This is because if the motor 3 is driven while the cover part 2 is being mounted, the eccentric pin 17 rotates eccentrically to drive the treatment element 4 on the cover part 2 side, making it difficult to mount the cover part 2. This is because the safety is improved by suppressing inadvertent movements.

  In the said Example, although the drive part of the main-body part 1 was shown by what eccentrically rotates the eccentric pin 17 with the motor 3, it is not limited to what performs such a movement, For example, it showed by the said gazette A thing may be used. Obviously, the configuration of the treatment element 4 is not limited to the illustrated example.

  In addition, although a display using a light emitting diode is shown here as the display unit 14, a liquid crystal display or the like may be used, or a display that emits a warning sound such as a buzzer may be used.
