Description

  The present invention relates to a shower head, and more particularly to a scalp washing shower head suitable for scalp washing in addition to normal washing.

  In recent years, attention has been focused on hair care and hair growth, but scalp care can be broadly divided into 1) hair care and 2) scalp care. Traditionally, hair care was the main focus, and shampoos, rinses, hair restorers, etc. were used to moisturize the hair and prevent split ends. Recently, however, there is a growing interest in scalp care due to the need for radical hair care. That is, excess sebum and dirt on the scalp, or coloring agents, shampoos, and rinses may not supply enough oxygen, causing hair loss, dandruff, and itching, and it is impossible to keep the hair strong. The need to keep clean on a daily basis has been recognized.

  Therefore, there is an interest in methods for washing hair in the shower during bathing. Usually, the hair is foamed with shampoo and washed with shower water, but this method is effective for washing the hair, but it is difficult to remove the sebum and dirt from the pores of the scalp by being blocked by wet hair and water film. Scratching with a nail or brush may hurt the scalp. That is, the scalp is not sufficiently cared for.

  Several shower devices for cleaning the scalp have been proposed. One of them is, for example, a scalp scrubber with a built-in pump or the like installed in a bathroom, and the pressure of tap water is increased by the pump to create a water discharge flow (see Patent Document 1). In other words, the scalp is washed by striking the scalp with a strong water discharge, and although a certain effect is expected, an electric device is installed in the bathroom, and the device is set and rewashed after washing the hair. There are problems such as being troublesome, taking a long time to charge, and not having an appliance in the bathroom.

There has also been proposed a shower head provided with a large number of brush-like projections, each of which has a hollow inside to project a trickle of water from the tip of the projection (see Patent Document 2). By washing hair with brush-like protrusions directly in contact with the scalp, the scalp is intended to be washed without being obstructed by wet hair or water film. However, even if such a brush comes into contact with the scalp, the scalp is naturally covered with water (film) during hair washing, so to remove the sebum and dirt from the pores against it, the water pressure of the water discharge should be increased. Must be high. However, in general, a shower head in a bathroom is for washing not only the hair but also the body. If the water pressure is high, the usability becomes uncomfortable or uncomfortable, and it is not practically possible.
Patent Publication 2003-210238 JP-A-11-225827

  Accordingly, an object of the present invention is to increase the water pressure when washing the scalp without using a special device such as an electric pump, and to bring the water flow ejected from the brush-like protrusions directly into contact with the scalp. It is possible to provide a shower head that can be effectively used, and can be easily switched to a normal water pressure when the body is washed, and used as usual.

  In order to solve the above-mentioned object, according to an embodiment of the scalp washing shower of the present invention, the scalp has a plurality of brush-like nozzles that have pores therein and eject water, and the nozzle and the water discharge are directly applied to the scalp. In the shower head that contacts the scalp and cleans the scalp, the shower head further includes a shower head housing having a male screw portion on the outer periphery of the water discharge side, a brush portion that integrally holds the plurality of brush-like nozzles, and an inner side. An annular holder that is a female screw part that is screwed with the male screw part, and when cleaning the scalp, the brush part is inserted between the male screw part and the annular holder, and the male screw part and the annular holder The brush portion is fixed to the shower head by screwing a female screw portion.

  Furthermore, a screen having pores for discharging a normal water pressure and a normal amount of water as a shower is provided. During normal cleaning, the screen is inserted between the male screw portion and the annular holder, and the male screw portion and the annular holder are inserted. The screen is fixed to the shower head by screwing with a female screw portion.

  In addition, it is preferable that the number and diameter of the pores of the brush portion be smaller and smaller than the number and diameter of the pores of the screen to discharge high-pressure water.

  As described above, the scalp can be effectively washed with high-pressure shower water without requiring a special device using an electric pump as a power source. In addition, the body can be washed as usual by easily switching to normal shower water.

  1a and 1b show the appearance of the scalp washing shower head 1, FIG. 1a shows a front view thereof, and FIG. 1b shows a side view thereof. 2 is an exploded view of the shower head 1, FIG. 2a is an exploded view of the shower head 1 during scalp cleaning, and FIG. 2b is an exploded view of the shower head 1 during normal cleaning.

  The shower head 1 basically includes a shower head upper housing 2 and a shower head middle housing 3, and one end of the upper housing 2 and the middle housing 3 are screwed and connected via a packing 8. The housing 3 is connected to the shower hose via the packing 9. The inside of the middle housing 3 is hollow, and a cartridge 10 containing a component that removes, for example, the chlorine content of tap water and protects the hair is inserted therein.

  The brush part 4 includes a plurality of brush-like nozzles 41 and a brush holding part 42. Each brush-like nozzle 41 is formed of a flexible material such as silicon rubber, and is integrally fixed to the brush holding portion 42 via a common base (not shown). Each brush-like nozzle 41 (and the brush holding portion 42) is provided with a narrow hole (not shown) penetrating the inside thereof, through which shower water is passed, and shower water is discharged from the tip.

  The other end of the shower head upper housing 2, that is, the outer peripheral portion on the water discharge side is a male screw portion 21. Here, at the time of scalp washing, the brush portion 4 is fitted into the male screw portion 21, and from above, the brush holder 4 is engaged with the male screw portion 21 by screwing the annular holder 7 whose inside is screwed with the male screw portion 21. Is fixed to the upper casing 2 of the shower head (FIG. 2a).

  On the other hand, at the time of normal cleaning, the normal water discharge screen 5 is fitted into the male screw portion 21 via the packing 6, and the annular holder 7 is screwed onto the male screw portion 21 from above to fix the water discharge screen 5 to the shower head 1. (FIG. 2b).

  That is, the shower water passes from the shower hose through the cartridge 10 in the middle casing 3 of the shower head, passes through the upper casing 2, and is discharged from the brush section 4 during scalp cleaning and from the normal screen 5 during normal cleaning.

  Here, the number and diameter of the pores of the brush portion 4 are smaller and smaller than the screen 5 during normal cleaning. In other words, when the scalp is cleaned by attaching the brush portion 4, water having a stronger water pressure is discharged from the tip of the brush-like nozzle 41 than in normal cleaning.

  That is, the brush-like nozzle 41 is directly brought into contact with the scalp and washed with shower water with a strong water pressure, thereby effectively removing sebum and dirt from the pores of the scalp without being blocked by wet hair or water film. Can do.

  On the other hand, during normal cleaning, shower water may be discharged while the brush unit 4 is attached, but the discharge water of the brush unit 4 is high pressure, and is not convenient for normal cleaning, resulting in discomfort. Cheap. If the water pressure is reduced by reducing the amount of water, the user feels unsatisfactory. At the time of normal cleaning there, the holder 7 is reversely rotated to remove the brush portion 4, and instead the normal screen 5 is attached, and the holder 7 is screwed with the male screw portion 21 to fix the screen 5.

  That is, at the time of normal cleaning, the user can take a shower through the normal screen 5 with the normal water pressure and water volume, and the user does not feel uncomfortable or unsatisfactory.

  As described above, with the shower head 1 of the present invention, the scalp can be effectively cleaned by directly attaching the high pressure water ejected from the brush-like nozzle 21 to the scalp by attaching the brush part 4 during scalp cleaning. In addition, during normal cleaning, the screen 5 can be attached and a shower can be used at a normal water pressure and amount. Further, since the brush portion 4 and the screen 5 can be easily attached and detached, the scalp cleaning and the normal cleaning can be performed appropriately and quickly.

  Furthermore, the shower water is passed through the cartridge 10 in the middle housing 3 to remove chlorine, and by applying a component that protects the hair, comprehensive care of the scalp and hair becomes possible.

  The external appearance of the scalp washing shower head of the Example of this invention is shown, FIG. 1a is the front view.   It is the side view.   FIG. 2A is an exploded view of the scalp washing shower head according to the embodiment of the present invention, and FIG.   It is an exploded view at the time of attaching the screen 5 and carrying out normal cleaning.
