Description

  The present invention is a device for caring for the scalp, which arranges many flexible protrusions like a brush and moves each protrusion individually to simultaneously scrub the scalp and scrape dirt around the hair root. .

Conventionally, there were devices that only rub the scalp and dedicated devices that only scrape dirt, but there were no devices that could simultaneously perform these operations.
This is because the operation of rubbing and the operation of scraping dirt are considered to be unrelated to each other.
In addition, the conventional device that only massages (Patent Document 1) changes the interval between the brush tips by moving the central part of the base part to which the brush is attached, and the movement is simple and the massage effect is low. .
However, according to the study of the present inventor, to remove the dirt on the pores, it is much easier to rub the scalp, that is, while massaged, than to perform only the scraping operation without massage. It turned out to be easy. It is presumed that this is because when the blood flow of the scalp is promoted by massage and the skin temperature rises, the subcutaneous tissue of the pores is activated, and dirt that sinks into the pores tends to come out.

Hereinafter, an embodiment of a scalp care device according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a scalp care device, which has an egg shape as shown in FIG. 1 and has a bottom surface of a hollow gear case 1a covered with a plate-shaped presser plate 4. The gear case 1a is large enough to fit in the palm, and the operation button 2 and the display lamp 3 are provided on the upper surface.
A rechargeable battery E, a motor M, gears 12 and 13 and the like are accommodated in the gear case 1a (FIGS. 7 and 8).
As shown in FIGS. 5 and 6, a swivel rod (stagnation rod) 14 that stands up at a predetermined angle is fixed to the lower end side of the low-speed shaft 27 of the large-diameter gear 12. Further, a swiveling rod (scraping rod) 15 standing at a predetermined angle is fixed to the lower end side of the high speed shaft 28 of the small diameter gear 13. The number of teeth is about 1.5 to 2 times greater for the large gear 12 than for the small gear 13.
A large-diameter gear 12a for receiving power is fixed to the low-speed shaft 27 of the large-diameter gear 12 with the swivel rod 14 standing at a predetermined angle, and the gear 12b is fixed to the shaft extending from the center of the upper surface.
The gear 12b and the motor M are connected by gears 20 to 24, and the rotation of the motor M is reduced to about 1/70 to 1/80 and transmitted to the low speed shaft 27.

Reference numeral 25 denotes a brush plate, which is a waterproof plate having the same size as the inner periphery of the presser plate 4 and is made of a flexible material such as silicon rubber. On the side surface of the brush plate 25, a plurality of convex strips 26 having a semicircular cross-section around the side surface are provided. (Fig. 9)
Further, the brush plate 25 has a plurality of squeezing columnar brushes 5 (two in a row in the figure) at the center of the bottom surface. Further, a plurality of scraping columnar brushes 6 are provided on the outer periphery of the squeezing columnar brush 5. Further, a plurality of fixed brushes 7 are implanted at predetermined positions on the bottom surface of the brush plate 25.
The massaging columnar brush 5 is thicker than the scraping columnar brush 6. Further, hollow portions 8 and 9 for inserting swivel rods 14 and 15 are respectively provided at the bottoms of the columnar brush 5 for rubbing and the columnar brush 6 for scraping. Further, a hemispherical stagnation portion 10 is attached to the tip of the stagnation columnar brush 5. A plurality of conical small protrusions 11 are attached to the tip of the columnar brush 6 for scraping.
The fixed brush 7 has a conical shape with a rounded tip, and its base is thinner than the columnar brush 6 for scraping.
Then, the massaging rod 14 is inserted through the hollow portion 8. At this time, a gap is formed between the tip of the stagnation rod 14 and the innermost part of the hollow portion 8.
Further, the scraping rod 15 is inserted into the hollow portion 9. At this time, no gap is generated between the scraping rod 15 and the innermost portion of the hollow portion 9.
The angle deviated from the high speed shaft 28 and the low speed shaft 27 (the one-dot chain line in FIG. 6) is larger than that of the scraping rod 14. Therefore, the swinging width of the columnar brush 5 for stagnation connected to the squeezing rod 14 is larger than the swinging width of the columnar brush 6 for scraping connected to the swivel rod 15.
Further, the rubbing rods 14 and the scraping rods 15 are arranged so as to be non-parallel to each other. In particular, it is preferable that the stagnation rod 14 inclines adjacent ones in opposite directions.
Further, a pair of fixing protrusions 18 are fixedly provided at the center of the bottom surface of the brush plate 25.
The fixing protrusion 18 is shorter than the brushes 5 to 7 and rounds the tip.
The holding plate 4 is provided with holes 19 in portions corresponding to the brushes 5 to 7 and the fixing protrusions 18 (see FIG. 9).

The scalp care device 1 waterproofs the joint portion between the gear case 1a and the presser plate 4 by a known means such as O-ring.
Further, when the brush plate 25 is fitted to the presser plate 4, the convex band 26 comes into contact with the wall surface of the presser plate 4 to close the gap between the two and waterproof.

  Further, a load sensor (not shown) is connected to the columnar brush 5 for scraping and the columnar brush 6 for scraping, and the columnar brush 5 for scraping and the columnar brush 6 for scraping regardless of whether the power is on. When the rotation speed of the motor is below a predetermined value, a control means (not shown) for performing control to stop the motor M is provided.

  In the scalp care device 1 configured as described above, when the operation button 2 is pressed to turn on the power, the display lamp 3 is lit and the swiveling rods 14 and 15 are rotated. Along with this, the columnar brush 5 for stagnation and the columnar brush 6 for scraping draw a circle while their tips repeat contact and separation. Since the large-diameter gear 12 has about 1.5 to 2 times as many teeth as the small-diameter gear 13, the stagnation columnar brush 5 draws a large ring and rotates slowly. The scraping columnar brush 6 draws a small ring and rotates quickly.

The scalp care apparatus 1 moves the brushes 5 to 7 so as to slowly come out by lightly pressing the brushes 5 to 7 on the scalp in the same manner as normal brushing.
The massaging columnar brush 5 massages the scalp so that it is slowly massaged. At this time, the scalp is not damaged by the hemispherical stagnation portion 10 at the tip of the columnar brush 5 for stagnation. Further, the gap between the columnar brush 5 for stagnation and the hollow portion 8 causes the columnar brush to be easily bent at the portion of the gap, so that there is no possibility of damaging the scalp even if it rotates in a large circle. Furthermore, the columnar brush 6 for scraping massages while scrubbing the scalp. These massages improve blood circulation in the head and dirt on the pores comes up near the surface. The small conical protrusion 11 at the tip of the scraping columnar brush 6 scrapes off the dirt that has been raised near the surface.
Further, the scalp care device 1 may be used after lathering shampoo with hair like the shampoo.
In addition to the above effects, a scrubbing effect is added, and the scalp becomes cleaner.

When the stubborn columnar brush 5 and the scraping columnar brush 6 are strongly pressed against the scalp, when the hair is caught, the rotation of the motor M is stopped by the control means, and the stubborn columnar brush 5 and Since the scraped columnar brush 6 is stationary, the scalp and hair are prevented from being damaged. In addition, it is possible to prevent accidents such as missing gears and swiveling rods due to the load being applied only to a part of the columnar brush 5 for rubbing or the columnar brush 6 for scraping.
Further, the fixing protrusion 18 can prevent an unexpected finger from being caught.

As shown in FIG. 11, the scalp care device 1 can also attach a sponge plate 16 to the presser plate 4.
The sponge plate 16 has a rectangular shape, and has a through hole 17 at a position corresponding to the fixing protrusion 18 and the stagnation columnar brush 5. Further, the thickness h of the sponge plate 16 is smaller than the height H of the massaging columnar brush 5 (h <H). Therefore, when the fixing projection 18 and the columnar brush 5 for stagnation are inserted into the through-hole 17 and the sponge plate 16 is attached to the scalp care device 1, the tip of the columnar brush 5 for stagnation is from the sponge plate 16. Protruding.
When using, after applying a suitable amount of shampoo and hot water to the sponge plate 16, press the operation button 2 to turn on the power, and when the foaming bubbling columnar brush 5 causes foaming, push the brush part lightly onto the scalp. Move it so that it hits slowly.
After use, the sponge plate 16 is removed, and the scalp care device 1 and the sponge plate 16 are cleaned.

In the above embodiment, the length of the columnar brush 5 for rubbing, the columnar brush 6 for scraping, the fixed brush 7 and the fixing protrusion 18 is not particularly determined, but the central portion is short and the peripheral portion is longer. When placed, it matches the shape of the head and is easy to use.
Further, the stagnation columnar brush 5, the scraping columnar brush 6 and the fixed brush 7 may be arranged in any way, but the stagnation columnar brush 5 is implanted in the center as in the above embodiment. When the columnar brush 6 and the fixed brush 7 for scraping are arranged around the periphery, there is an advantage that the sponge plate 16 is easily fixed and the sponge plate 16 is easily foamed.
Moreover, in the said embodiment, the hemispherical stagnation part 10 is attached to the front-end | tip of the columnar brush 5 for stagnation, and the conical small protrusion 11 is attached to the front-end | tip of the columnar brush 6 for scraping. However, the present invention is not limited to this. However, if the tip has this shape, it is possible to efficiently massage the scalp and scrape dirt.
In the above embodiment, the fixed brush 7 is planted. However, if a large number of columnar brushes 5 for scraping and columnar brushes 6 for scraping are planted, the fixed brush 7 is unnecessary. However, when the fixed brush 7 is implanted, the rotating brushes 5 and 6 are not adjacent to each other like the fixing protrusion 18, and an accident in which a finger is pinched between the rotating brushes 5 and 6 can be prevented.
Moreover, in the said embodiment, although it has the press plate 4, this invention is not restricted to this, The press plate 4 may be abbreviate | omitted and the bottom part of the gear case 1a may be plugged up with the brush plate 25. However, when the presser plate 4 is provided, the waterproof performance is improved.
Moreover, in the said embodiment, although the space | gap is provided between the stagnation rod 14 and the hollow part 8 of the columnar brush 5 for stagnation, this invention is not limited to this, The hemispherical stagnation part 10 and columnar shape are not limited to this. When the brush 5 is soft, there may be no gap. However, by providing the gap, it can be formed of the same material as the columnar brush 6 for scraping, and the molding becomes easy.
