Description

[Technical Field]

[0001] The present invention relates to a shower head with a water spray function. [Background technology]

[0002] With the spread of micro-nano bubble technology, many showerheads have become known for supplying mist-like moisture. Among these, showerheads equipped with comb-shaped nozzles that spray moisture from the tips have been developed (see, for example, Patent Document 1). This is said to effectively cleanse the scalp. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-185461 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a shower head is equipped with comb teeth to create a so-called brush shape, users use the shower head in a motion similar to combing their hair. Simply discharging water from the tips of the comb teeth during this motion is ineffective because, for example, if the tips of the comb teeth are in close contact with the scalp, the water will not come out easily. Furthermore, supplying water while the comb teeth are in contact with the scalp can cause some damage to the scalp. Furthermore, since a brush-shaped shower head provides the above-mentioned action, it is necessary to devise a way to make combing hair easier.

[0005] The present invention has been made in consideration of the above-mentioned conventional technology, and aims to provide a shower head that can easily comb hair and can effectively deliver the moisture ejected to the scalp. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a showerhead comprising: a handle having an attachment portion at its rear end to be attached to a shower hose through which shower water is supplied; a head portion formed at the tip of the handle; main teeth and sub-teeth protruding from the surface of the head portion; a main tooth row in which the main teeth are arranged in multiple rows to form a comb-like shape; a sub-teeth row in which the sub-teeth are arranged in multiple rows to form a comb-like shape and are arranged parallel to the main tooth row; outlet holes formed at the tips of the main teeth through which the shower water is discharged; and a protrusion formed by the tip portions of the main teeth extending to a position higher than the outlet holes.

[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-tooth rows are formed in two rows on either side of the main tooth row with a gap between them, and when viewed in a plane, the sub-tooth rows are arranged in a position parallel to the direction in which the gripping portion extends.

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

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

[0011] Preferably, the surfaces of the main teeth and sub-teeth are plated. [Effects of the Invention]

[0012] According to the present invention, because the outlet holes are provided at the tips of the main teeth, shower water is discharged from these holes, allowing shower water to be provided from a position closer to the scalp. In this case, because the tips of the main teeth have protrusions located higher than the outlet holes, even if the tips of the main teeth hit the scalp, the outlet holes are prevented from being blocked by the scalp. Therefore, even if the user presses the tips of the main teeth against the scalp as when combing their hair, shower water can be efficiently provided to the scalp from the outlet holes.

[0013] In addition, the protrusions are formed on the tip surfaces of the main teeth at opposing positions across the discharge hole, improving the effectiveness of combing hair. The presence of multiple protrusions reliably prevents the discharge hole from coming into close contact with the scalp. The shower water flows from the discharge hole along the shape of the protrusions, improving the flow of shower water. In addition, because there are multiple protrusions on each main tooth, the pressure applied to the scalp is dispersed, allowing for gentle combing of hair.

[0014] Furthermore, by having one row of main teeth and two rows of sub-tooth, the number of comb teeth can be kept to a minimum, and there is sufficient space between the main and sub-tooth rows to prevent damage to hair when combing. Furthermore, because the sub-tooth rows are arranged parallel to the direction in which the grip extends in a plan view of the showerhead, both the main and sub-tooth rows are arranged parallel to the longitudinal direction of the showerhead in a plan view. Due to the shape of the showerhead, users move the showerhead in a direction perpendicular to the longitudinal direction of the showerhead when combing their hair, so arranging the main and sub-tooth rows in this way creates a structure in which the entire row catches hair.

[0015] Furthermore, since the tip of the protrusion is positioned higher than the tip of the adjacent sub-tooth, the main tooth from which the shower water is ejected always comes into contact with the scalp first, allowing shower water to be efficiently provided close to the scalp.

[0016] Furthermore, by providing water spray holes, shower water can also be supplied to the surface of the hair, so that shower water can be supplied to the scalp and hair at the same time.

[0017] Furthermore, at least the main teeth and sub-teeth are plated, which reduces friction when they come into contact with hair, making it easier to comb. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] As shown in FIGS. 1 to 5, the showerhead 1 of the present invention is intended to be attached to a shower hose from which shower water is supplied. Users can easily use the showerhead 1 of the present invention by replacing the showerhead attached to a shower hose already installed in their existing home. The showerhead 1 is equipped with a handle 2 at its rear end. A mounting part 18 for attaching to a shower hose is formed at the rear end of the handle 2. The showerhead 1 is equipped with a head part 3 at its other end (front end). Main teeth 4 and sub-teeth 5 protrude from the surface of the head part 3. The main teeth 4 are spaced apart along the extension of the handle 2 in a plan view (see FIG. 4). The main teeth 4 are arranged in a row, forming a comb-like shape. In the illustrated example, the main teeth 4 are arranged in a single row 6, and the showerhead 1 has one main tooth row 6.

[0020] Similarly, multiple sub-tooths 5 are arranged in rows at intervals to form a sub-tooth row 7. The sub-tooth row 7 is also comb-shaped like the main tooth row 6. The sub-tooth row 7 is arranged parallel to the main tooth row 6. In the example shown in the figure, the sub-tooth row 7 is formed in two rows on either side of the main tooth row 6 at intervals. In plan view, the sub-tooth row 7 is arranged parallel to the main tooth row 6 in the extension direction of the gripping portion 2.

[0021] Each main tooth 4 constituting the main tooth row 6 has an outlet hole 8 at its tip. This outlet hole 8 is where the shower water supplied from the shower hose is discharged. The tip of the main tooth 4 has a portion that extends higher than the outlet hole 8, and this portion serves as a protrusion 9. In the example shown in the figure, the protrusions 9 are formed at opposing positions on the tip surface of the main tooth 4, sandwiching the outlet hole 8 therebetween. In other words, two protrusions 9 are provided at the tip of the main tooth 4, and are positioned in the front-to-rear direction of the showerhead (axial direction in plan view) relative to the outlet hole 8.

[0022] As described above, because the outlet holes 8 are provided at the tips of the main teeth 4, shower water is discharged from these holes, allowing shower water to be provided from a position closer to the scalp. At this time, because the protrusions 9 are located at the tips of the main teeth 4 at a position higher than the outlet holes 8, the scalp will not be blocked by the outlet holes 8 even if the tips of the main teeth 4 come into contact with the scalp. Therefore, even if the user presses the tips of the main teeth 4 against the scalp as when combing their hair, shower water can be efficiently provided to the scalp from the outlet holes 8.

[0023] In addition, the protrusions 9 are formed on the tip surfaces of the main teeth 4 at opposing positions across the discharge hole 8, improving the effectiveness of combing hair. The presence of multiple protrusions 9 (two protrusions 9 per main tooth 4 in the illustrated example) reliably prevents the discharge hole 8 from coming into close contact with the scalp. The shower water flows from the discharge hole 9 along the shape of the protrusions 9 (in the illustrated example, it flows left and right), improving the flow of shower water. In addition, because there are multiple protrusions 9 per main tooth 4, the pressure when it comes into contact with the scalp is dispersed, allowing you to comb your hair while being gentle on the scalp.

[0024] Furthermore, by providing one row of main teeth 6 and two rows of sub-tooth 7, the number of comb teeth can be kept to a minimum, and there is sufficient space between the main teeth 6 and the sub-tooth 7, preventing damage to hair when combing. Furthermore, because the sub-tooth 7 is arranged parallel to the direction in which the handle 2 extends in a plan view of the showerhead 1, both the main teeth 6 and the sub-tooth 7 are arranged parallel to the longitudinal direction of the showerhead 1 in a plan view. Due to the shape of the showerhead 1, when combing hair, the user moves the showerhead 1 in a direction perpendicular to the longitudinal direction of the showerhead 1. Therefore, arranging the main teeth 6 and the sub-tooth 7 in this way creates a structure in which the entire row catches hair. This allows the showerhead 1 to be used in the same way as combing hair.

[0025] The tip of this protrusion 9 is located higher than the tip of the sub-tooth 5 adjacent to the main tooth 4 on which the protrusion 9 is formed. In other words, in terms of the relationship between the main tooth 4 and the sub-tooth 5 adjacent to each other in the left-right direction of the showerhead 1 (the direction perpendicular to the axial direction in a plan view), the protrusion 9 formed on the main tooth 4 is located at the highest position. As a result, the tip of the protrusion 9 is located higher than the tip of the adjacent sub-tooth 5, so the main tooth 4 from which shower water is ejected always comes into contact with the scalp first, allowing shower water to be provided efficiently close to the scalp.

[0026] A plurality of spray holes 10 for spraying shower water are formed on the surface of the head portion 3 (the surface from which the main teeth 4 and sub-teeth 5 protrude). By providing these spray holes 10, shower water can be sprayed onto the surface of the hair as well, and shower water can be simultaneously delivered to the scalp and hair.

[0027] Furthermore, the surfaces of the main teeth 4 and the sub-teeth 5 are plated. By plating at least the main teeth 4 and the sub-teeth 5 in this way, friction when they come into contact with hair is reduced, making it easier to comb.

[0028] As is clear from FIG. 6 , the rear end of the handle 2 is designed to be connectable to a shower hose, and shower water flows in through the water inlet 11 provided in the mounting portion 18. The handle 2 is hollow, and the shower water passes directly through the handle 2 and flows into the receiving portion 12, which is formed continuously with the handle 2. A micro-nano bubble device may be housed in the handle 2, and the shower water supplied from the discharge holes 8 and spray holes 10 may be used as micro-nano bubble water. A surface portion 13 is located above the receiving portion 12 and is fixed to the receiving portion 12 by screws. Spray holes 10 are formed in the surface portion 13. A water delivery portion 14 is placed in the center of the surface portion 13 in the left-right direction, along the axial direction of the showerhead 1 in a plan view. The water delivery portion 14 is inserted into the main tines 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 feed portion 14 in accordance with 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. Shower water is supplied from the discharge holes 8 by fitting the protrusions 16 into the main teeth 4. After the surface portion 13, water feed portion 14, and comb tooth plate 15 are placed on the receiving portion 12, they are screwed together with the fixing ring portion 17 to fix their relative positions.
