Description

Shower Head

[0001] The present invention relates to a shower head having a water sprinkling function.

[0002] With the popularization of micro-nano bubble technology, many shower heads that supply mist-like moisture have become known. Under such circumstances, shower heads provided with comb-tooth-shaped nozzles that discharge moisture from the tips thereof have been developed (see, for example, Patent Document 1). It is claimed that this enables effective cleaning of the scalp.

[0003] Japanese Unexamined Patent Publication No. 2007-185461

[0004] However, when comb teeth are provided on a shower head to form a so-called brush shape, a user performs an operation of combing hair with the shower head. In such an operation, merely discharging moisture from the tips of the comb teeth is not effective, because for example, when the tips of the comb teeth are in close contact with the scalp, it becomes difficult for moisture to discharge. In addition, supplying moisture while the shower head is in contact with the scalp raises no small concern about damage to the scalp. Furthermore, since the above operation is provided with a brush shape, a contrivance for facilitating hair combing is also required.

[0005] The present invention has been made in consideration of the above-mentioned prior art, and an object of the present invention is to provide a shower head that can facilitate hair combing even as a shower head, and can further effectively supply discharged moisture to the scalp.

[0006] In order to achieve the above object, the present invention provides a shower head characterized by comprising: a grip portion having at a rear end thereof a mounting portion to be mounted to a shower hose to which shower water is supplied; a head portion formed at a tip of the grip portion; main teeth and sub teeth protruding from a surface of the head portion; a main tooth row in which the plurality of main teeth are arranged in rows to form a comb tooth shape; a sub tooth row in which the plurality of sub teeth are arranged in rows to form a comb tooth shape and which is disposed in parallel with the main tooth row; a discharge hole provided at a tip of the main tooth for discharging the shower water; and a projection formed by extending a tip portion of the main tooth to a position higher than the discharge hole.

[0007] Preferably, the protrusions are formed at opposing positions on the tip surfaces of the main teeth, with the discharge hole in between.

[0008] Preferably, the sub-dentition is formed in two rows, with a gap between it and the main dentition, and in a plan view, the sub-dentition is positioned parallel to the direction in which the gripping portion extends.

[0009] Preferably, the tip of the projection is positioned higher than the tip of the sub-tooth adjacent to the main tooth on which the projection is formed.

[0010] Preferably, the surface of the head portion has a plurality of spray holes formed therein for spraying the shower water.

[0011] Preferably, the main teeth and sub teeth have their surfaces plated.

[0012] According to the present invention, since a discharge hole is provided at the tip of the main tooth, shower water is discharged from here, allowing the shower water to be provided from a position closer to the scalp. At this time, since there is a projection at the tip of the main tooth that is higher than the discharge hole, even if the tip of the main tooth touches the scalp, it is possible to prevent the discharge hole from being blocked by the scalp. Therefore, even if the user presses the tip of the main tooth against the scalp as if combing their hair, the shower water can be efficiently provided to the scalp from the discharge hole.

[0013] Furthermore, since the protrusions are formed on the tip surface of the main teeth, flanking the discharge holes, the hair-combing effect is improved. The presence of multiple protrusions ensures that the discharge holes do not come into close contact with the scalp. The shower water from the discharge holes flows along the shape of the protrusions, improving the flow of the shower water. In addition, because there are multiple protrusions relative to the main teeth, the pressure applied when the brush comes into contact with the scalp is distributed, allowing for gentle hair-combing.

[0014] Furthermore, by having one row of main teeth and two rows of sub-teeth, the number of comb teeth can be minimized, and there is sufficient space between the main and sub-teeth, preventing damage to the hair when combing. In addition, since the sub-teeth are positioned parallel to the direction in which the gripping part extends when viewed from above, both the main and sub-teeth are positioned parallel to the longitudinal direction of the shower head when viewed from above. Due to the shape of the shower head, when a user combs their hair, they move the shower head in a direction perpendicular to the longitudinal direction of the shower head, so by arranging the main and sub-teeth in this way, the entire row can receive the hair.

[0015] Furthermore, because the tip of the protrusion is positioned higher than the tips of the adjacent sub-teeth, the main teeth from which the shower water is discharged always make contact with the scalp first, allowing for efficient delivery of shower water close to the scalp.

[0016] Furthermore, by providing water spray holes, shower water can be supplied to the surface of the hair, allowing shower water to be supplied to both the scalp and hair simultaneously.

[0017] Furthermore, the plating of at least the main and sub teeth reduces friction when in contact with the hair, resulting in smoother combing.

This is a schematic perspective view of the shower head according to the present invention. This is a schematic plan view of the shower head according to the present invention. This is a schematic side view of the shower head according to the present invention. This is a schematic exploded view of the shower head according to the present invention.

[0019] As shown in Figures 1 to 5, the shower head 1 according to the present invention is to be attached to a shower hose to which shower water is supplied. Users can easily use the shower head 1 according to the present invention by replacing the shower head attached to the shower hose installed in their existing home. One end of the shower head 1, the rear end, is provided with a gripping portion 2. An attachment portion 18 for attachment to the shower hose is formed at the rear end of the gripping portion 2. The other end of the shower head 1, the front end, is provided with a head portion 3. Main teeth 4 and sub-teeth 5 are formed protruding from the surface of the head portion 3. Multiple main teeth 4 are arranged at intervals along the direction in which the gripping portion 2 extends in a plan view (see Figure 4). That is, multiple main teeth 4 form a row, giving it a comb-like shape. In the example shown in the figure, multiple main teeth 4 form a row of main teeth 6, and this row of main teeth 6 is provided on the shower head 1.

[0020] Similarly, multiple sub-teeth 5 are arranged in rows with spacing between them, forming a sub-dentition 7. The sub-dentition 7, like the main dentition 6, has a comb-like shape. The sub-dentition 7 is positioned parallel to the main dentition 6. In the example shown in the figure, the sub-dentition 7 is formed in two rows, with spacing between them and flanking the main dentition 6. In a plan view, the sub-dentition 7 is positioned parallel to the main dentition 6 in the direction in which the gripping portion 2 extends.

[0021] Here, each main tooth 4 forming the main tooth row 6 is provided with a discharge hole 8 at its tip. This discharge hole 8 is where the shower water supplied from the shower hose is discharged. Furthermore, there is a portion of the tip of the main tooth 4 that extends to a position even higher than the discharge hole 8, and this is a projection 9. In the example shown in the figure, the projections 9 are formed on opposite sides of the discharge hole 8 on the tip surface of the main tooth 4. That is, there are two projections 9 at the tip of the main tooth 4, and their positions are formed in the front-to-back direction (axial direction in a plan view) of the shower head relative to the discharge hole 8.

[0022] As described above, since a discharge hole 8 is provided at the tip of the main tooth 4, shower water is discharged from here, allowing the shower water to be provided from a position closer to the scalp. At this time, since there is a projection 9 at the tip of the main tooth 4 that is higher than the discharge hole 8, even if the tip of the main tooth 4 touches the scalp, it is possible to prevent the discharge hole 8 from being blocked by the scalp. Therefore, even if the user presses the tip of the main tooth 4 against the scalp as if combing their hair, the shower water can be efficiently provided to the scalp from the discharge hole 8.

[0023] Furthermore, since the protrusions 9 are formed on the tip surfaces of the main teeth 4, flanking the discharge holes 8, the hair-combing effect is improved. Having multiple protrusions 9 (two protrusions 9 for each main tooth 4 in the example shown) reliably prevents the discharge holes 8 from coming into close contact with the scalp. The shower water from the discharge holes 9 flows along the shape of the protrusions 9 (flowing left and right in the example shown), improving the flow of the shower water. In addition, since there are multiple protrusions 9 for each main tooth 4, the pressure applied when in contact with the scalp is distributed, allowing for gentle hair-combing.

[0024] Furthermore, by having one row of main teeth 6 and two rows of sub-teeth 7, the number of comb teeth can be minimized, and there is sufficient space between the main teeth 6 and sub-teeth 7, preventing damage to the hair when combing. In addition, since the sub-teeth 7 are positioned parallel to the direction in which the gripping part 2 extends when viewed from above, both the main teeth 6 and sub-teeth 7 are positioned parallel to the longitudinal direction of the shower head 1 when viewed from above. Due to the shape of the shower head 1, when the user combs their hair, they move the shower head 1 in a direction perpendicular to the longitudinal direction of the shower head 1, and by arranging the main teeth 6 and sub-teeth 7 in this way, the entire row can receive the hair. Therefore, the shower head 1 can be used as if combing hair with a comb.

[0025] The tip of this projection 9 is positioned higher than the tips of the adjacent sub-tooths 5 to the main tooth 4 on which the projection 9 is formed. In other words, in the relationship between adjacent main tooth 4 and sub-tooths 5 in the left-right direction of the showerhead 1 (in the direction perpendicular to the axial direction in a plan view), the projection 9 formed on the main tooth 4 is positioned at the highest point. As a result, the tip of the projection 9 is positioned higher than the tips of the adjacent sub-tooths 5, so that the main tooth 4 from which the shower water is discharged always makes contact with the scalp first, allowing for efficient delivery of shower water close to the scalp.

[0026] Multiple water spray holes 10 for spraying shower water are formed on the surface of the head portion 3 (the side on which the main teeth 4 and sub teeth 5 protrude). By providing such water spray holes 10, shower water can be supplied to the surface of the hair, and shower water can be supplied to the scalp and hair simultaneously.

[0027] Furthermore, the main teeth 4 and sub-teeth 5 have plated surfaces. In this way, the plating of at least the main teeth 4 and sub-teeth 5 reduces friction when they come into contact with the hair, resulting in smoother combing.

[0028] As is clear from Figure 6, the rear end of the gripping part 2 is structured to be connectable to a shower hose, and shower water flows in through the water inlet hole 11 provided in the mounting part 18. The inside of the gripping part 2 is hollow, and the shower water passes directly through the gripping part 2 and flows into the receiving part 12 which is formed continuously with the gripping part 2. Alternatively, a micro-nanobubble device may be housed inside the gripping part 2, and the shower water supplied from the discharge hole 8 and spray hole 10 may be micro-nanobubble water. Above the receiving part 12, a surface part 13 is positioned, which is fixed to the receiving part 12 by screwing it in. Spray holes 10 are formed in this surface part 13. In the central part of the surface part 13 in the left-right direction, a water supply part 14 is placed along the axial direction of the shower head 1 in a plan view. This water supply part 14 is inserted inside the main teeth 4.

[0029] A comb-tooth plate 15 is placed on the surface portion 13. Main teeth 4 and sub-teeth 6 are formed on this comb-tooth plate 15. Protrusions 16 are formed on the water supply portion 14 according to the number of main teeth 4. The protrusions 16 are hollow and have holes at their tips. These holes are positioned to correspond to the discharge holes 8. When each protrusion 16 is housed within the main teeth 4, shower water is supplied from the discharge holes 8. After the surface portion 13, water supply portion 14, and comb-tooth plate 15 are placed on the receiving portion 12, they are screwed together with the fixing annular portion 17 to fix their positions relative to each other.
