Description

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

  In recent years, as coloring has become widespread and the number of mature people who are concerned about hair has increased, attention and hair growth have attracted attention. Hair care can be broadly divided into 1) hair care and 2) scalp care. Conventionally, hair care has been the main focus. It was preventing. Recently, however, fundamental hair care has been demanded, and interest in scalp care has increased. 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 a strong interest in the method of washing hair in the shower. 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.

  Therefore, several shower devices for washing 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 powerful water discharge flow, 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.

In addition, there has 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 the hair by bringing the brush-like protrusions directly into contact with the scalp, the scalp is intended to be washed without being obstructed by wet hair or a water film. However, even if such a brush is brought 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 this, Must be quite expensive. 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.

  Further, when washing the hair, it is desirable to remove the chlorine content of the tap water through the shower head and add a component that protects the hair because the chlorine of the tap water damages the hair. It is well known and commercialized to remove chlorine from the showerhead and add a hair protection component, but from the viewpoint of hair care and hair growth, the scalp must be washed together with the scalp. Care is important.

  Therefore, the object of the present invention is to effectively clean the scalp using the high water pressure of the water supply without using a special device such as an electric pump, and easily switch the high pressure water to the normal water pressure. It is possible to provide a shower head that can also wash the body as usual. Another object of the present invention is to provide a shower head capable of comprehensively caring for hair by removing chlorine contained in tap water along with scalp washing and adding a hair protecting component.

  In order to solve the above problem, in an embodiment of the present invention, there are a plurality of brush-like nozzles that have pores inside and discharge water, and the nozzle and water discharge directly contact the scalp to remove the scalp. In the shower head to be cleaned, the shower head is further fixed to the shower head, a fixing portion having a female screw portion on the water channel side, a male screw portion screwed and connected to the female screw portion, and having a hollow inside and a water channel, A switching fixing part having a plurality of branch holes for branching the water flow, a water flow switching plate facing the water flow branch hole and switching the water flow from the branch hole, and a plurality of discharge holes for discharging shower water to the outside And a switching movable part. The water flow switching plate has a normal water discharge hole for discharging water for a normal shower and a high-pressure water discharge hole for scalp washing, and the switching movable portion is further rotatably fixed to the switching fixing portion. A holding portion and a switching lever that is integrally formed with the switching movable portion and that can rotate the entire switching movable portion with respect to the switching fixing portion. The shower head further includes a brush portion including a plurality of brush-like nozzles having internal pores and a brush holding portion for holding the nozzle. Each brush-like nozzle has a nozzle base portion as a common base, and the brush head The holding part and the brush-like nozzle are fixed integrally, and an opening hole through which shower water during normal shower is passed is provided in the peripheral part of the brush holding part. Then, during normal shower, shower water is discharged from the normal water discharge hole of the switching movable portion with a normal amount of water and water pressure through the fixed portion and the switching fixing portion, and when the scalp is washed, the switching lever is rotated. Thus, the switching movable portion is rotated, the water flow from the branch hole is switched to close the normal water discharge hole, and shower water is discharged at a high pressure only from the high pressure water discharge hole for scalp washing.

  In the above scalp shower head, it is preferable that a water pressure increasing tool for increasing the discharge water pressure is further provided in the switching movable portion.

  Furthermore, the scalp and the hair can be comprehensively cared for by removing the chlorine contained in the tap water in the shower head middle housing and inserting a cartridge to which the hair protecting component is added.

  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. Furthermore, the body can be washed as usual by switching to normal water pressure shower water by the water flow switching mechanism. In addition, the scalp can be cleaned and the chlorine content in tap water can be removed, and the hair protection component can be added to comprehensively care for the hair.

  FIG. 1 shows the appearance of a scalp washing shower head 1 according to an embodiment of the present invention, FIG. 1a shows a front view thereof, and FIG. 1b shows a side view thereof. The shower head 1 includes a shower head upper housing 2, a shower head middle housing 3, and a shower head lower housing 4. A brush unit 20 (not shown) is detachably attached to the upper housing 2, the shower head middle housing 3 and the lower housing 4 are screwed together, and the lower housing 4 is screwed with a shower hose (not shown). To do.

  FIG. 2 shows a sectional view of the shower head 1 in a state where the brush portion 20 is attached to the upper housing 2. Shower water is discharged from the shower head lower casing 4 through the middle casing 3, the upper casing 2, and the brush section 20 as indicated by arrows in the figure.

  3A and 3B show a detailed sectional view of the structure inside the shower head upper housing 2 and the brush portion 20. The brush unit 20 includes a brush holding unit 21 and a plurality of brush-like nozzles 22 held by the holding unit 21. Each brush-like nozzle 22 has a nozzle base 23 as a common base, and is integrally formed of a flexible material such as silicon rubber. A plurality of nozzle through holes 24 (not shown) penetrating the respective brush-like nozzles 22 are provided in the central part of the brush-holding part 21, and the brush-like nozzles 22 are passed through the holes 24, and the brush holding part 21. By fixing the back surface and the nozzle base 23 with an adhesive or the like, the brush holding part 21 and the brush-like nozzle 22 are fixed together. An opening hole 25 through which shower water during normal shower (described later) passes is formed in the peripheral portion of the brush holding portion 21.

  Each brush-like nozzle 22 (and its base portion 23) has pores inside and allows shower water to pass therethrough, and discharges the shower water from the nozzle tip.

  The brush holding portion 21 has a hook portion 26 on the outer peripheral portion thereof, and the brush portion 20 is inserted into the fitting portion 11 provided around the shower head upper casing 2 and rotated to rotate the brush portion 20 to the upper portion of the shower head. It can be attached to the housing 2 and can be easily removed by rotating in the opposite direction.

  The structure in the shower head upper housing 2 is roughly divided into a fixed portion 12, a switching fixing portion 13, and a switching movable portion 14. The fixing portion 12 is fixed through a screw hole (not shown) formed integrally with the housing 12 in the upper housing 2 and has a female screw portion 121 on the water channel side. The switching fixing portion 13 is screwed and coupled to the female screw portion 121 of the fixing portion 12, and has a male screw portion 131 having a hollow inside and serving as a water channel, and branch holes 132a and 132b for branching the water flow. The switching movable part 14 has a water flow switching plate 141 that faces the water flow branch holes 132a and 132b and switches the water flow from the branch holes 132, and a plurality of discharge holes 142a and 142b that discharge shower water to the outside. The water flow switching plate 141 has a normal water discharge hole 141a for normal shower water discharge and a high-pressure water discharge hole 141b (see FIG. 3B) for scalp washing. The switching movable unit 14 is further formed integrally with a holding unit 143 that is rotatably fixed to the switching fixing unit 13 and the switching movable unit 14, and a switching lever that can rotate the entire switching movable unit 14 relative to the switching fixing unit 13. 144.

  Here, during a normal shower, as shown in FIG. 3 a, the water flow passes through the water flow branch hole 132 a from the male screw portion 131 of the switching fixing portion 13 and passes through the normal water discharge hole 141 a of the water flow switching plate 141 of the switching movable portion 14. It passes through and is discharged from both the water discharge hole 142a and the water discharge hole 142b behind the brush-like nozzle 22.

  When cleaning the scalp, when the switching lever 144 of the switching movable part 14 is rotated, the entire switching movable part 14 is rotated and the switching plate 141 is also rotated. As shown in FIG. The normal water discharge hole 141a facing the 132a is closed. Instead, the water flow branch hole 132b and the high-pressure water discharge hole 141b are opened, and the shower water passes only through the water discharge hole 142b behind the brush-like nozzle 22 and the tip of the nozzle 22 It is discharged from.

  That is, since the shower water passes through only the water discharge hole 142b behind the brush-like nozzle 22 and is discharged, the water pressure becomes higher than the normal shower discharged from both the water discharge hole 142a and the water discharge hole 142b, and the scalp is effective. Can be cleaned automatically.

  That is, it is possible to easily switch between normal shower water and scalp washing shower water simply by rotating the switching lever 144, and normal shower and scalp washing can be performed without a sense of incongruity.

  As yet another embodiment, as shown in FIG. 4, for example, a rotating piece 60 is provided as a water pressure increasing / maintaining tool in order to further increase the pressure of the water flow in the switching movable portion 14. The rotary piece 60 is normally used for saving water, and even if the flow rate is reduced, the rotary piece 60 has an effect of giving momentum to the water and not giving the user a sense of decrease in volume during use. The rotary piece 60 includes, for example, a main body 61 having six narrow water channels therein and, for example, three blades 62 that freely rotate when the water flow of the water channels hits.

  Here, when tap water is passed, the high-pressure water flow that has been squeezed and passed through the water channel in the main body 61 hits the blades 62 one after another, and the blades 62 continuously rotate at a high speed. That is, each high-pressure flow in the plurality of narrow water channels is converted into the rotational force of the blades 62, and thrust is applied to the water. In this case, the water flow receiving the thrust does not increase because the amount of water decreases, but it has been experimentally found that the water pressure increases by about 20% when compared with the same amount of water.

  That is, when the scalp is washed, the amount of water discharge is reduced because the water channel is limited to the water discharge hole 142b. Become.

  By separating the shower head middle housing 3 and the lower housing 4, a cartridge (not shown) for removing chlorine contained in tap water and adding a hair protecting component can be inserted into the interior space. By discharging shower water through the scalp and hair, you can care comprehensively.

  An appearance of a scalp washing shower head according to an embodiment of the present invention is shown, and FIG.   It is the side view.   It is sectional drawing which shows each part of the scalp washing shower head of the Example of this invention.   FIG. 3A is a detailed cross-sectional view of the upper housing 2 of the scalp washing shower head according to the embodiment of the present invention. FIG.   The operation of each part and the flow of water during scalp washing are shown.   Another embodiment is shown with a rotating piece that maintains and increases the momentum of the water.
