Description

[Technical Field]

[0001] The present invention relates to a water discharge member and a treatment device used for scalp massage and the like. [Background Art]

[0002] Conventionally, hair and beauty facilities such as hair salons are provided with shampoo bowls for washing the hair of a person receiving treatment. The person receiving treatment places their head on the shampoo bowl, and receives treatment from a practitioner from the side or the top side of the person's head. Treatments using a shampoo bowl include, for example, shampooing, scalp massage, and the like, and depending on the treatment, it takes several tens of minutes to about one hour. When a treatment that requires a long time is performed, if the neck of the person receiving treatment directly comes into contact with the edge of the shampoo bowl, the person may feel pain in the neck. Therefore, for example, the shampoo bowl-attached pillow described in Patent Document 1 below (hereinafter referred to as "the invention of known literature 1") is attached to the edge of the shampoo bowl, and functions as a cushion so that the neck of the person receiving treatment does not directly hit the edge of the shampoo bowl.

[0003] On the other hand, in addition to treatment, practitioners have many other tasks, and need to perform, for example, cleaning, tool maintenance, telephone response, confirmation of store visit reservations, and the like. However, if a practitioner is tied up with a long treatment, they cannot perform other tasks during that time. Therefore, there is a demand for a treatment that is comfortable for the person receiving treatment and does not cause any inconvenience even if the practitioner performs other tasks. As such a treatment, for example, continuously pouring hot and cold water over the head of the person receiving treatment or keeping the head immersed in hot and cold water (hereinafter referred to as "head bath") can be considered. [Prior Art Literature] [Patent Literature]

[0004] [Patent Document 1] Registered Utility Model No. 3185374 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] The invention described in prior art document 1 is unclear as to whether it allows for head immersion bathing, whether it is suitable for head immersion bathing, and whether it can achieve a head immersion bathing experience that satisfies the patient. At the very least, it seems impossible to continuously pour water over the patient's head without the patient's assistance. Furthermore, the following issues can be raised regarding the invention in prior art document 1. Because the invention in prior art document 1 is installed between the patient's neck and the rim of the shampoo bowl, the position of the patient's head relative to the bottom of the shampoo bowl is higher compared to when the invention is not used. In this case, even if water is filled into the shampoo bowl, the water will overflow from the rim of the shampoo bowl before the water level reaches the patient's head, and the head will not be immersed in the water. Even if it were possible to raise the water level without overflowing to the patient's head, it would require a large amount of water, making it uneconomical.

[0006] This invention was proposed in view of the above circumstances. Specifically, it aims to provide a water discharge member and treatment device that are comfortable for the patient and allow the practitioner to perform treatments without interfering with other tasks. [Means for solving the problem]

[0007] To achieve the above objective, the water discharge member according to the present invention is a water discharge member installed inside a shampoo bowl on which a person to be treated has a flow channel portion extending upward toward the shampoo bowl and a water discharge portion connected to the tip of the flow channel portion, characterized in that the hot and cold water discharged from the water discharge portion is U-shaped, following the hairline on the forehead of the person to be treated. The water discharge member according to the present invention is characterized in that the hot and cold water discharged from the water discharge section forms a continuous curtain-like stream without interruption from the water outlet. The water discharge member according to the present invention is characterized in that the water discharge portion is connected with a gap between it and the lower part of the tip portion at the end of the extended flow channel portion. The water discharge member according to the present invention is characterized in that the flow path portion is composed of a pair of left and right sections, and by changing the angle of the flow path portion, the position in which the hot and cold water from the water discharge portion hits the hair of the person being treated, rather than being at a position away from the hair. The treatment device according to the present invention is characterized by comprising the above-described water-discharging member and a bucket-shaped member installed inside the shampoo bowl in which the hot water from the water-discharging part collects. Furthermore, a head immersion bathing method can also be realized using a water discharge member and a treatment device. Specifically, the head immersion bathing method is characterized by the following steps: an installation procedure in which a water discharge member with an adjustable water discharge position and a bucket-shaped member capable of accommodating the head of the person being treated are installed inside the shampoo bowl in which the person being treated is being treated; an immersion procedure in which hot water is collected in the bucket-shaped member at a water discharge position away from the head of the person being treated, who is positioned face up in the bucket-shaped member, and the back of the head of the person being treated is immersed in the hot water; a discharge procedure in which the water discharge position away from the head of the person being treated is adjusted to a position where the water is directed at the hair of the person being treated, and the hot water is directed at the hair of the person being treated; and an overflow procedure in which the hot water accumulated in the bucket-shaped member is overflowed from the neck side of the person being treated. With this configuration, the person being treated can relax as their head is immersed in hot water, and dirt is removed from their hair as their hair is immersed in the hot water along with their head. Furthermore, the water flows over the nape of the neck, the hairline, and the sides of the neck (hereinafter referred to as "nape, etc.") of the person receiving treatment. Since the nape, etc. is not submerged in a still surface of water but is exposed to continuously flowing water, the person receiving treatment does not experience discomfort and can relax by feeling the water flow. In addition, after the back of the head is submerged in the water, or after the nape, etc. is exposed to the water, the hair is moderately stimulated by the water from the water outlet, so the person receiving treatment can properly feel the flowing water on the nape, etc. At the same time, the treatment continues even if the practitioner is performing other tasks. Therefore, the treatment is comfortable for the person receiving treatment and can be performed without interfering with the practitioner's other tasks.

[0008] The head immersion bathing method is characterized in that the spout of the water discharge member is U-shaped, conforming to the hairline on the patient's forehead. With this configuration, the water hits the scalp and hairline on the patient's forehead, and the scalp and hairline are moderately stimulated by the water from the spout member, allowing the patient to relax.

[0009] The head immersion bathing method is characterized by including a drainage procedure in which the water overflowing from the bucket-shaped member is drained by flowing it down the inner surface of the shampoo bowl. With this configuration, the water is drained inside the shampoo bowl and does not spill onto the outside of the shampoo bowl or onto the floor.

[0010] The head immersion bathing method is characterized in that, in the water discharge procedure, hot water is applied to the scalp and / or hairline on the forehead of the person receiving treatment, and flows down the hair toward the top of the head. The hot water hits the scalp or hairline, the scalp and hairline, and flows down the hair toward the top of the head. The person receiving treatment can relax as their scalp and hairline are moderately stimulated by the hot water from the water discharge member, feeling the water flow.

[0011] The head immersion method can also be implemented using the following device. Specifically, the head immersion device has a bottom portion positioned above the bottom surface of the shampoo bowl on which the person being treated is receiving treatment, and a circumferential side portion connected to the periphery of the bottom portion and extending upward, wherein the circumferential side portion has a neck edge portion that faces the neck rest portion on the side edge of the shampoo bowl on which the person being treated is resting, and is characterized by holding warm water for immersing the person's head. That is, in the shampoo bowl, warm water is collected in the head immersion device. Because the neck edge portion of the head immersion device faces the neck rest portion of the shampoo bowl, when the person being treated places their neck on the neck rest portion, their head is immersed in the warm water. During this time, the person being treated can relax as their head is immersed in the warm water, and dirt is removed from their hair as it is immersed along with their head. Meanwhile, the treatment continues even if the practitioner is performing other tasks. Therefore, the treatment is comfortable for the person receiving it, and the practitioner can perform other tasks without any interference. Also, because the bottom is positioned higher than the bottom of the shampoo bowl, less water is needed compared to filling the shampoo bowl directly with water.

[0012] The head immersion device is characterized by its ability to immerse the back of the patient's head when filled with water. That is, the back of the patient's head is submerged in the water, allowing the patient to relax. Therefore, it is comfortable for the patient, and the practitioner can perform the treatment without interfering with other tasks.

[0013] The head immersion device is characterized in that the neck edge faces the neck of the person receiving treatment without making contact with it. This configuration allows water to flow between the neck rest and the neck. The person receiving treatment can relax as water flows continuously around the back of their neck. Furthermore, because the treatment continues as the water flows, it is comfortable for the person receiving treatment, and the practitioner can perform other tasks without any interference.

[0014] The head immersion bathing device is characterized by having legs that rest on the bottom surface. Therefore, it can be stably installed in the shampoo bowl.

[0015] The head immersion device is characterized by having legs that hook onto the side edges. Therefore, it can be stably installed in the shampoo bowl.

[0016] The head immersion bathing device is characterized by having legs that fit into the drain of the shampoo bowl. Therefore, it can be stably installed in the shampoo bowl.

[0017] The head immersion device is characterized in that the neck edge has a facing portion that faces the neck of the person being treated, and water flow portions formed on both sides of the facing portion and cut out downward from the facing portion. With this configuration, when water accumulates and the water level rises, the water flows out from the water flow portions on both sides of the facing portion before the water level reaches the facing portion. In other words, the water continues to flow around the back of the person being treated's neck. Therefore, the person being treated can be relaxed.

[0018] The head immersion device has a bottom portion and a circumferential portion, a bucket body portion having a cutout in the part facing the neck rest portion to form a gap, and a neck edge portion that can be attached and detached in the gap, wherein the neck edge portion has a facing portion that faces the neck of the person being treated, water flow portions formed on both sides of the facing portion and cut out downward from the facing portion, and guide portions formed on both sides of the water flow portion that extend upward and protrude in a direction in which their tips move toward each other. With this configuration, various shapes and sizes of neck edges can be used depending on the type of treatment and the physique of the person being treated. In addition, the water flows from the guide portion to the tip portion by the force of the flow, and at the tip portion, it is directed towards the back of the person being treated and continues to flow. Therefore, the person being treated can be relaxed.

[0019] The head immersion device is characterized by having grooves formed on both sides of the water flow section and cut out towards the bottom, being shallower than the water flow section. Therefore, even if the person being treated is large in build and the water flow section is blocked around the back of the neck, preventing the water from flowing out of the water flow section, the water can still flow through the grooves, allowing the water to reach the back of the neck of the large person being treated.

[0020] The head immersion device is characterized in that the water flow section is cut out downwards from the water flow section, and has a mounting section on which the neck rest is positioned. That is, even if the neck rest is attached to the shampoo bowl, the neck rest is positioned in the mounting section, so that the neck rest does not interfere with the water flow section. The water flows from the neck rest and continues to flow around the back of the user's neck. Therefore, the user can be relaxed.

[0021] The shampoo bowl is characterized by having the head immersion device described above. Therefore, it exhibits the same effect as the head immersion device described above. [Effects of the Invention]

[0022] The water discharge member according to the present invention is installed inside a shampoo bowl where a person to be treated receives treatment, and comprises a flow path portion extending upward toward the shampoo bowl, and a water discharge portion connected to a distal end portion of the flow path portion, wherein the hot and cold water discharged from the water discharge portion has a U-shape that follows the hairline on the forehead of the person to be treated. The scalp and hairline of the person to be treated are moderately stimulated by the hot and cold water from the water discharge member, so the person to be treated can feel the water flow and relax. Meanwhile, the treatment continues even when the practitioner performs other tasks. Therefore, comfortable treatment that does not interfere with the practitioner performing other tasks can be provided while being comfortable for the person to be treated. The head soaking method comprises: an installation step of installing a water discharge member with an adjustable water discharge position and a tub-shaped member capable of accommodating the head of the person to be treated inside the shampoo bowl where the person to be treated receives treatment; a soaking step of storing hot and cold water in the tub-shaped member at a water discharge position away from the head of the person to be treated placed on his or her back in the tub-shaped member, and soaking the occipital region of the person to be treated in the hot and cold water; a water discharging step of adjusting the water discharge position away from the head of the person to be treated to a water discharge position that contacts the hair of the person to be treated, and applying the hot and cold water to the hair of the person to be treated; and an overflowing step of causing the hot and cold water stored in the tub-shaped member to overflow from the neck side of the person to be treated.

[0023] In the water discharge member according to the present invention, the hot and cold water discharged from the water discharge portion is in a continuous curtain shape without interruption from the water discharge outlet. With this configuration, the hot and cold water discharged from the water discharge outlet continues without interruption from the water discharge outlet until it contacts the forehead of the person to be treated, and the scalp and hairline of the person to be treated are continuously moderately stimulated by the hot and cold water, so the person to be treated can feel the water flow and relax.

[0024] In the water discharge member according to the present invention, the water discharge portion is connected with a gap to a lower part of the distal end portion where the flow path portion extends.

[0025] In the water discharge member according to the present invention, the flow path portion is configured as a pair of left and right flow path portions, and by changing the angle of the flow path portion, the position of the hot and cold water from the water discharge portion can be adjusted from a position away from the hair of the person to be treated to a position contacting the hair. The treatment device according to the present invention comprises the water-discharging member described above and a bucket-shaped member installed inside the shampoo bowl in which the water from the water-discharging part collects. The occipital part of the person receiving treatment is immersed in the water collected in the bucket-shaped member, allowing the person receiving treatment to relax.

[Modes for carrying out the invention]

[0027] The following is a description of the shampoo bowl and head immersion device used in the head immersion method. The shampoo bowl is fitted with treatment devices used in the treatment, such as a scalp massage device and a head immersion device. Figures 1 and 2 show the external appearance of the shampoo bowl 1. Figure 3 shows the scalp massage device 10 attached to the shampoo bowl 1. Figure 4 shows the scalp massage device 10 and the head immersion device 25 attached to the shampoo bowl 1. In Figure 1, the depth direction of the shampoo bowl 1 is defined as up and down (Up, Down), the side where the head of the person being treated 50 is placed in the shampoo bowl 1 is the back side, the opposite side where the neck is located is the front side, and the width direction is defined as the left side and right side.

[0028] As shown in Figures 1 and 2, the shampoo bowl 1 is for the person receiving treatment 50 to rest their head on while lying supine on a treatment table (not shown), such as a barber chair, and receive treatment (see Figure 32). Treatments include, for example, shampooing, scalp massage, coloring, perming, and eye makeup. The shampoo bowl 1 is a nearly hemispherical bowl composed of a bottom surface 2 and a side surface 3. A cylindrical drain 4 is formed in the bottom surface 2, and a shower head 5 from which hot water is discharged and a shut-off valve 6 for the hot water supply are installed on the inside of the side surface 3. The front side of the side surface 3 is recessed and formed lower than other parts of the side surface 3, and a neck rest 7 is attached as a neck rest for the person receiving treatment. The neck rest 7 is composed of a first resting part 8 that is shaped to be connected to the side surface 3, and a hemispherical second resting part 9 that is positioned behind the first resting part 8. The second resting part 9 is composed of a pair, left and right. The first mounting section 8 is where the neck of the person being treated 50 is placed, and the second mounting section 9 is where the nape of the neck of the person being treated 50 is placed.

[0029] As shown in Figures 3 and 4, the shampoo bowl 1 can be fitted with a scalp massage device 10 or a head immersion device 25 depending on the type of treatment. The scalp massage device 10 and the head immersion device 25 will now be described based on the drawings. Figures 5 to 10 show the external appearance of the scalp massage device 10, and Figures 11 to 15 show the external appearance of the scalp massage device 10 when it is attached to the shampoo bowl 1. Figures 16 to 25 show the external appearance of the head immersion device 25, and Figures 26 to 31 show the external appearance and cross-section of the head immersion device 25 when it is attached to the shampoo bowl 1.

[0030] As shown in Figures 5 to 10, the scalp massage device 10 is a water discharge member with an adjustable water discharge position. The scalp massage device 10 has a connected part 11 to which the shower head 5 is connected, a flow path part 13 connected to the connected part 11, a water discharge part 18 connected to the flow path part 13, and a detachable part 20 connected to the flow path part 13 and attached to the shampoo bowl 1. The connected part 11 is a cylindrical shape extending vertically, with an opening 12 at the top and the lower part connected to the flow path part 13. The opening 12 has a detachable fixing means (not shown) for fixing the shower head 5. The detachable fixing means is, for example, a string or band to tie the shower head 5, a head immersion device 25 as a weight to press down on the shower head 5 from above, a screw structure in which the opening 12 and the shower head 5 are screwed together, mechanical fitting, or the selection of a material to create friction between the opening 12 and the shower head 5, such as making the opening 12 out of rubber.

[0031] The flow path section 13 has a first flow path section 14 connected to the lower part of the connected section 11, and a second flow path section 16 connected to the first tip section 15, which is the tip of the first flow path section 14. Each flow path section 14, 16 is hollow on the inside, and a flow path is formed inside. The first flow path section 14 is composed of a pair, left and right, centered on the connected section 11. The first flow path section 14 extends from the connected section 11 to the left and right, and curves or bends forward, with the first tip section 15 pointing upward. The first tip section 15 has a hinge section 23 and a shaft support section 24. The hinge section 23 rotates the second flow path section 16 and moves it back and forth, and the second flow path section 16 is connected via this hinge section 23. The hinge section 23 has a restricting section (not shown) formed to limit the range of motion of the second flow path section 16. The shaft support portion 24 is a groove formed at the rear of each first tip portion 15, and is used when the head immersion device 25 is attached (see Figure 31).

[0032] The second flow channel section 16 extends upward from the left and right first tip sections 15 and curves or bends laterally, and is connected at the second tip section 17, which is the tip. The second tip section 17 has a water discharge section 18 connected to its lower part. The water outlet 19 of the water discharge section 18 is directed downward towards the shampoo bowl 1. The detachable section 20 has a first detachable section 21 that contacts the bottom surface 2 of the shampoo bowl 1 and a second detachable section 22 that is connected to the drain 4 of the shampoo bowl 1. The first detachable section 21 protrudes downward from the first tip section 15 and its length is adjusted by a screw structure or the like. The second detachable section 22 is plate-shaped and protrudes downward from the first flow channel section 14 directly below the connected section 11. The second detachable section 22 is made of, for example, rubber or silicone.

[0033] As shown in Figures 11 to 15, the scalp massage device 10 is attached to the shampoo bowl 1. Specifically, the second detachable part 22 of the scalp massage device 10 is inserted into the drain 4 of the shampoo bowl 1, and the side surface of the second detachable part 22 contacts the inner surface of the drain 4, causing the second detachable part 22 to fit into the drain 4 (see Figures 30 and 31). Since the drain 4 is cylindrical and the second detachable part 22 is plate-shaped, a gap is created between the second detachable part 22 and the drain 4. Therefore, hot water is drained from the drain 4 through this gap. The first detachable part 21 is placed against the bottom surface 2 of the shampoo bowl 1 and supports the respective flow channels 14 and 16. Therefore, each flow channel 14 and 16 is supported at three points by the respective detachable parts 21 and 22. When in use, the shower head 5 of the shampoo bowl 1 is connected to the connection part 11 (see Figure 30).

[0034] As shown in Figure 15, the second flow channel 16 changes angle with respect to the first flow channel 14 via the hinge portion 23. That is, the second flow channel 16 tilts towards the rear. Because a restricting portion is formed in the hinge portion 23, its range of motion is limited and it is prevented from changing beyond a predetermined angle. The predetermined angle is, for example, 25 to 35 degrees towards the rear, preferably about 30 degrees, and 5 to 15 degrees towards the front, preferably about 10 degrees, when the orientation of the second flow channel 16 is considered to be vertical (zero degrees). If the range of motion is excessively large, the scalp massage device 10 may come into contact with the side surface 3 of the shampoo bowl 1 when it is attached to the shampoo bowl 1, hindering the attachment process.

[0035] The second flow channel 16 is movable in the front-rear direction via the hinge 23. In other words, the position of the axis itself changes when the second flow channel 16 rotates.

[0036] As shown in Figures 16 to 25, the head immersion device 25 is a bucket-shaped member capable of accommodating the head of the person being treated 50. The head immersion device 25 is a bucket-shaped member that is similar to, for example, a washbasin and is slightly narrowed in a funnel shape, and has a bucket body 26 and a flow straightening portion 40 as the neck rim. Here, Figures 16 to 20 show the state before the flow straightening portion 40 is attached to the bucket body 26, and Figures 21 to 25 show the state of the head immersion device 25 with the flow straightening portion 40 attached to the bucket body 26. The bucket body 26 has a bottom portion 27 and a circumferential side portion 28 that is connected to the periphery of the bottom portion 27 and extends upward. The bottom portion 27 is formed in steps, and a part of the circumferential side portion 28 is cut out. Because the bottom portion 27 is formed in steps, a recessed space 29 is formed on the outer side of the back of the bottom portion 27. Specifically, a bottom side portion 30 extending upwards is connected to the rear side of the bottom portion 27, and a stepped bottom portion 31 is connected to the rear side of this bottom side portion 30. Multiple legs 32 for self-support are formed on the underside of the bottom portion 27. The number, shape, length, and position of the legs 32 are arbitrary. A drain hole 33 is formed approximately in the center of the bottom portion 27. A plug 34 (see Figure 30) can be attached to and removed from the drain hole 33.

[0037] Of the circumferential portion 28, the portion on the front side facing the neck rest 7 is notched to form a neck edge gap 48. A flow straightening portion 40 is attached to and detached from this neck edge gap 48. Of the circumferential portion 28, the outer edge portion 35, which is the portion other than the neck edge gap 48, has shaft projections 36 formed on its outer surface. The shaft projections 36 consist of a pair, left and right, and protrude laterally on the front side of the bottom portion 30. On the upper edge of the outer edge portion 35, near the neck edge gap 48 on the front side, a pair of grooves 38 are formed on the left and right. Of the outer edge portion 35, near the neck edge gap 48, a plurality of small holes 39 are formed along the shape of the neck edge gap 48.

[0038] The flow straightening section 40 is, for example, a thin plate made of rubber, silicone, or urethane, and is fastened to the circumferential side portion 28 of the barrel body portion 26 by a fastening member 47, forming the neck edge. The fastening member 47 is shaped to conform to the neck edge gap 48, and fastens the flow straightening section 40 between it and the circumferential side portion 28 using screws or the like. The flow straightening section 40 has a circumferential main body portion 41 fastened to the circumferential side portion 28, an opposing portion 42 connected to the upper part of the circumferential main body portion 41, a water flow portion 43 formed by cutting out both the left and right sides of the opposing portion 42, and guide portions 45 formed on both the left and right sides of the water flow portion 43. The opposing portion 42 protrudes upward from the center of the upper end of the circumferential main body portion 41. Because both the left and right sides of the opposing portion 42 are cut downward toward the circumferential main body portion 41, the water flow portion 43 is formed below the opposing portion 42. The water flow section 43 is further cut downward toward the circumferential main body section 41, forming the mounting section 44. The second mounting section 9 of the neck mounting device 7 is positioned on this mounting section 44 (see Figure 26). The guide section 45 extends upward from the upper end of the circumferential main body section 41, and its tip, the guide tip section 46, protrudes in a direction toward each other. In relation to the flow straightening section 40, the groove section 38 is positioned along the circumferential direction of the outer edge section 35, outside the mounting section 44 (water flow section 43) and the guide tip section 46, and is cut shallower than the water flow section 43 toward the bottom section 27 from the outer edge section 35.

[0039] As shown in Figures 26 to 31, the head immersion device 25 is attached to the shampoo bowl 1 to which the scalp massage device 10 is installed. The connection part 11 of the scalp massage device 10 is connected to the shower head 5 of the shampoo bowl 1, and the stepped bottom part 31 of the head immersion device 25 rests on top of the shower head 5. In other words, the head immersion device 25 serves as the means for attaching and detaching the scalp massage device 10. Note that the means for attaching and detaching may also be realized by using a string or band in combination. The shaft projection 36 of the head immersion device 25 is locked to the shaft support part 24 of the scalp massage device 10. On the other hand, the flow straightening part 40 of the head immersion device 25 is attached to the second mounting part 9 of the neck rest 7. That is, the second mounting part 9 is fitted into the mounting part 44 of the flow straightening part 40, the mounting part 44 is closed, and the second mounting part 9 replaces the water flow part 43. The opposing portion 42 of the rectifier portion 40 is fitted between the second mounting portions 9. The guide portion 45 is fitted along the outer circumference of the second mounting portion 9. The rectifier portion 40 faces the first mounting portion 8 of the neck rest 7. The bottom portion 27 of the head immersion device 25 is positioned above the bottom surface 2 of the shampoo bowl 1, and a plug 34 is attached to the drain hole 33 of the bottom portion 27.

[0040] As described above, the scalp massage device 10 and the head immersion device 25 are configured as described.

[0041] Next, the effects of this embodiment will be explained along with the operation of this embodiment. Figures 32 to 34 show the procedure according to this embodiment. The procedure includes at least the following steps: a seating procedure in which the person to be treated 50 lies down on the treatment table; an installation procedure in which the scalp massage device 10 and the head immersion device 25 are installed inside the shampoo bowl 1; an immersion procedure in which water is filled into the head immersion device 25 and the back of the head of the person to be treated 50 is immersed in the water; a discharge procedure in which the water is directed onto the hair of the person to be treated 50; an overflow procedure in which the water accumulated in the head immersion device 25 is allowed to overflow from the neck side of the person to be treated 50; a drainage procedure in which the water overflowing from the head immersion device 25 is drained by running it down the inner surface of the shampoo bowl 1; a removal procedure in which the scalp massage device 10 and the head immersion device 25 are removed from the shampoo bowl 1; and a drying procedure in which the hair of the person to be treated 50 is dried. In this embodiment, the procedure is in the order of seating, installation, flooding, overflowing, water discharge, drainage, removal, and drying, or in the order of seating, installation, flooding, water discharge, overflowing, drainage, removal, and drying. The drainage procedure may be performed at any time after the flooding, overflowing, or water discharge procedure.

[0042] As shown in Figures 32 to 34, in the seating procedure, the person being treated 50 lies on their back and places their head in the shampoo bowl 1. At this time, the person being treated 50's neck is placed on the first resting part 8 of the neck rest 7. Furthermore, the nape of the person being treated 50's neck is placed on the second resting part 9. The person being treated 50's hair is wet with hot water from the showerhead 5 before the treatment. Wetting the hair beforehand prevents the hot water from splashing off the hair during the treatment. If the treatment were performed with dry hair, the hot water released from the scalp massage device 10 might hit the hair and splash back, potentially splashing onto the person being treated 50's face or clothing.

[0043] In the installation procedure, with the head of the person being treated 50 resting on the shampoo bowl 1, the scalp massage device 10 is attached to the shampoo bowl 1. The second flow channel section 16 of the scalp massage device 10 is attached in a position tilted backward. By tilting the second flow channel section 16 backward, the scalp massage device 10 is attached to the shampoo bowl 1 in a position where the water outlet section 18 does not face the face of the person being treated 50. If the scalp massage device 10 were attached to the shampoo bowl 1 with the second flow channel section 16 in a vertical position, the water remaining in the water outlet section 18 from other treatments may splash onto the face or clothing of the person being treated 50.

[0044] The shower head 5 is connected to the connection part 11 of the scalp massage device 10. If the attachment / detachment means is, for example, a band, the shower head 5 is tied to the connection part 11. The head immersion device 25 is positioned below the back of the head and is attached to the scalp massage device 10 and placed on top of the shower head 5. The attachment of the head immersion device 25 to the scalp massage device 10 provides an attachment / detachment means in combination with a band or the like. When the head immersion device 25 is positioned below the back of the head, if the person being treated 50 has long hair, the person being treated 50's head is lifted and all of their hair is contained inside the head immersion device 25.

[0045] With the scalp massage device 10 and head immersion device 25 attached to the shampoo bowl 1 on which the head of the person being treated 50 is placed, the second flow path section 16 of the scalp massage device 10 remains tilted backward. As a result, the water discharge section 18 is positioned away from the head of the person being treated 50, towards the top of the person being treated 50's head, and does not face the scalp or hairline. On the other hand, the facing section 42 of the head immersion device 25 faces the nape of the neck of the person being treated 50. However, the facing section 42 does not come into contact with the nape of the neck, leaving a small gap between the nape of the neck and the facing section 42. Note that which part of the neck, nape of the neck, etc., is placed on each of the placement sections 7, 8 will vary slightly depending on the physique of the person being treated 50.

[0046] In the immersion procedure, when the shut-off valve 6 of the shampoo bowl 1 is operated and hot water is supplied, the hot water is discharged from the shower head 5. Since the shower head 5 is connected to the connected part 11 of the scalp massage device 10, the hot water is discharged from the connected part 11, through the first flow path 14 and the second flow path 16, and out of the outlet 19 of the discharge part 18. The discharged hot water does not hit the head of the person being treated 50, but accumulates in the head immersion device 25. In the overflow procedure, as the water level gradually rises from the bottom 27 of the head immersion device 25, the back of the head is adequately immersed in the hot water, and when the water level reaches the second mounting part 9 of the neck rest 7, the hot water detours to the left and right along the second mounting part 9 (see water flow 51 in Figure 33), and overflows and flows outside the head immersion device 25 from the left and right of the second mounting part 9 (see water flow 52 in Figure 34). At that time, the hot water does not flow beyond the opposing section 42. Since the nape of the neck of the person being treated 50 is placed on the second resting section 9, the hot water flows along the second resting section 9 and over the nape of the neck. Because the nape of the neck is not submerged in a still water surface but is exposed to continuously flowing hot water, the person being treated 50 does not experience any discomfort in the nape of the neck and can relax by feeling the water flow.

[0047] Depending on the force of the water flow, the water may also flow from the second mounting section 9 to the guide section 45, and then from the guide tip 46 towards the nape of the neck, etc. (see water flow 53 in Figure 33). Because the water is directed appropriately towards the nape of the neck, etc., the person being treated 50 can be relaxed.

[0048] When the water level reaches the second mounting section 9, the unit becomes full. At this point, the back of the head of the person receiving treatment 50 is submerged in the water, which helps to relax the person receiving treatment 50. In addition, as the hair is submerged in the water along with the head, dirt is washed away from the hair.

[0049] After the back of the head has been adequately immersed in the water, or after the water has overflowed and flowed out of the head immersion device 25 from the left and right sides of the second mounting section 9, in the water discharge procedure, the water discharge position, which is away from the head of the person being treated 50, is adjusted to a position where the water will hit the hair of the person being treated 50. That is, the angle of the second flow path section 16 is adjusted so that the second flow path section 16 is positioned so that the water discharged from the water outlet 19 hits the scalp and hairline. The water hits the scalp and hairline and flows down the hair towards the top of the head (see water flow 54 in Figure 34). After the back of the head has been immersed in the water, or after the nape of the neck has been exposed to the water, the person being treated 50's scalp and hairline are adequately stimulated by the water from the water outlet 19, allowing them to properly feel the flow of water on their nape. If the water from the spout 19 is poured into the head immersion device 25 while hitting the scalp and hairline, the scalp and hairline may be stimulated before the nape of the neck is exposed to the water, and the person receiving the treatment 50 may experience a decrease in sensation in the nape of the neck.

[0050] During the treatment, as described above, the person receiving the treatment 50 can relax as their head is submerged in water and water flows over their neck, etc., while the treatment continues even if the practitioner is performing other tasks. Therefore, the treatment is comfortable for the person receiving the treatment 50, and the practitioner can perform other tasks without any problems. Furthermore, even if the practitioner is performing the treatment, the scalp massage device 10 acts as a shower, so the practitioner does not need to hold the shower head 5 and can perform the treatment with both hands.

[0051] Furthermore, since the bottom 27 of the head immersion device 25 is positioned higher than the bottom 2 of the shampoo bowl 1 (see Figure 34), a smaller amount of water is sufficient compared to when water is directly poured into the shampoo bowl 1.

[0052] In the drainage procedure, the water overflowing from the head immersion device 25 flows along the inner surface of the shampoo bowl 1 and is drained from the drain port 4 of the shampoo bowl 1. The water overflowing from the head immersion device 25 does not flow down the nape of the neck, etc., onto the body of the person being treated or outside the shampoo bowl 1, but rather flows along the inner surface of the shampoo bowl 1 and is drained. Therefore, the water does not spill onto the outside of the shampoo bowl 1 or onto the floor.

[0053] In this embodiment, the second mounting portion 9 of the neck rest 7 is fitted into the mounting portion 44 of the flow straightening portion 40 in the head immersion device 25 (see Figure 26). That is, even if the neck rest 7 is attached to the shampoo bowl 1, the second mounting portion 9 is positioned in the mounting portion 44 so that the second mounting portion 9 does not interfere with the flow straightening portion 40.

[0054] Once the treatment is complete, the shut-off valve 6 is operated to stop the water flow. During the removal procedure, the second flow channel section 16 is tilted backward and positioned so as not to face the head of the person receiving treatment 50. Therefore, even if any water remaining in the flow channel section 13 drips from the outlet 19, it is prevented from hitting the head.

[0055] In this embodiment, a drain hole 33 is formed in the bottom 27 of the head immersion device 25 and a plug 34 is attached to it (see Figure 30). By removing the plug 34, the water can be drained from the drain hole 33.

[0056] The head immersion device 25 is removed from the scalp massage device 10. The shower head 5 is removed from the scalp massage device 10. In the drying procedure, the client's wet hair is dried with a fibrous material such as a towel.

[0057] In this embodiment, the flow straightening section 40 of the head immersion device 25 is attached and detached via a retaining member 47 (see Figures 16 to 25), so that flow straightening sections 40 of various shapes can be attached and detached depending on the type of treatment and the physique of the person receiving treatment 50. Furthermore, since the flow straightening section 40 is a thin plate made of rubber, silicone, urethane, etc., it can be easily deformed and replaced.

[0058] In this embodiment, a pair of left and right grooves 38 are formed on the upper edge of the outer edge 35 of the head immersion device 25, near the neck edge gap 48 on the front side (see Figure 22). The grooves 38 are positioned along the circumferential direction of the outer edge 35, outside the placement section 44 (water flow section 43) and the guide tip section 46, and the grooves 38 are cut out shallower than the water flow section 43 from the outer edge 35 towards the bottom 27. If the person being treated 50 is large in stature and the opposing section 42 of the head immersion device 25 comes into contact with the nape of the neck of the person being treated 50, the second placement section 9 will be blocked by the nape of the neck, preventing the water from flowing over the nape of the neck. However, since the water flows from the grooves 38, which are shallower than the water flow section 43, the water can flow over the nape of the neck of the large person being treated 50.

[0059] In other embodiments of the present invention, the head immersion device 25 does not have a placement section 44 and has a water flow section 43 (see Figures 21 and 22). In this case, the water level gradually rises from the bottom 27 of the head immersion device 25 and, upon reaching the water flow section 43, overflows from the water flow section 43, which is lower than the opposing section 42, to the outside of the head immersion device 25. At that time, since the opposing section 42 is formed higher than the water flow section 43, the water does not flow beyond the opposing section 42. Since the water flow section 43 faces the nape of the neck of the person being treated, the water flows over the nape of the neck of the person being treated. In this case, the second placement section 9 may or may not be present.

[0060] Next, the effects of the scalp massage device 10 used in this embodiment will be explained.

[0061] The second flow channel section 16 of the scalp massage device 10 extends upward from the first tip 15 of the first flow channel section 14 and is curved or bent laterally (see Figure 7). This configuration prevents the second flow channel section 16 from interfering with the head of the person receiving treatment 50.

[0062] The first tip 15 of the scalp massage device 10 has a hinge portion 23, and the second flow channel portion 16 changes angle with respect to the first flow channel portion 14 via the hinge portion 23 (see Figure 15). This configuration allows the position of the water discharge portion 18 to change, and the position at which the hot and cold water discharged from the water outlet 19 hits the scalp can be adjusted. In addition, it facilitates the installation process on the shampoo bowl 1.

[0063] Furthermore, the hinge portion 23 has a restricting portion formed therein to limit the range of motion of the second flow channel portion 16. This configuration limits the range of motion of the second flow channel portion 16, preventing it from changing beyond a predetermined angle. Therefore, for example, the hot water will not splash onto the face of the person being treated 50.

[0064] The second flow channel 16 is movable in the front-rear direction via the hinge 23. Therefore, the second flow channel 16 is appropriately positioned according to the position of the hairline of the person being treated 50.

[0065] Next, modified examples of the scalp massage device 10 will be described based on the drawings. Figures 35 to 37 show the modified scalp massage device 110. Figures 35 and 36 show the external appearance of the scalp massage device 110, and Figure 37 shows an enlarged cross-section of the scalp massage device 110 with the second detachable part 122 inserted into the drain 4 of the shampoo bowl 1. In the following, the differences in configuration from the scalp massage device 10 will be mainly described, and the same configuration as the scalp massage device 10 will be used with the same reference numerals and their description will be omitted.

[0066] As shown in Figures 35 and 36, the second attachment / detachment section 122 of the scalp massage device 110 has a pair of flange portions 155 that protrude toward the front and rear from the lower part of the front and rear sides. When viewed from above, the flange portions 155 are approximately semicircular. When viewed from the side, the flange portions 155 have a flat upper surface portion 156 which is the top surface and an inclined lower surface portion 157 which is the bottom surface. The flat upper surface portion 156 is a flat semicircular disc shape, and the inclined lower surface portion 157 is gradually inclined downward from the outer tip toward the second attachment / detachment section 122.

[0067] As shown in Figure 37, when the second detachable part 122 is inserted into the drain 4 of the shampoo bowl 1, the flange part 155 is positioned deeper than the upper end of the opening of the drain 4 and with a gap between it and the inner surface of the drain 4. The hot water drained from the drain 4 passes through a mesh-like hair collector (not shown) installed inside the drain 4. At that time, the hot water flows from the flat upper surface part 156 down the inclined lower surface part 157 to the bottom of the drain 4. That is, the flowing hot water may make an unpleasant noise for the person being treated 50 when it hits the hair catcher, but because the hot water is drained via the flange part 155, the position where the hot water starts to fall is lowered to the lower end of the inclined lower surface part 157, which is lower than the bottom surface 2 of the shampoo bowl 1, so the distance from where the hot water starts to fall to where it hits the hair collector is also shortened. Therefore, compared to the case where there is no flange portion 155 and the hot water starts to fall from the bottom surface 2, a sound-dampening effect is achieved, and the person receiving treatment 50 can relax without feeling any unpleasant noise.

[0068] In other embodiments of the present invention, only the head immersion device is attached to the shampoo bowl. In this case, the legs of the head immersion device are made long and stand independently on the bottom surface of the shampoo bowl. Alternatively, instead of a scalp massage device, a stand is installed in the shampoo bowl, and the head immersion device is placed on this stand. Even without a scalp massage device, a head immersion is preferable because, even if a practitioner is performing the treatment, the practitioner can perform the treatment with both hands. In other embodiments, the legs are hook-shaped and designed to hook onto the side edge of the shampoo bowl. In other embodiments, the legs are shaped to fit into the drain of a shampoo bowl, and have a configuration similar to, for example, the second detachable part of a scalp massage device. Other embodiments do not have legs. In other embodiments, the opposing part makes slight contact with the nape of the neck or other parts of the person being treated. Other embodiments do not have a water flow section. In other embodiments, there is no flow straightening section, and a neck rim portion with the same shape as the flow straightening section is formed on the main body of the barrel as a portion corresponding to the flow straightening section. Other embodiments do not have grooves. In other embodiments, the plug is integrated with the flow straightening section. That is, the lower end of the flow straightening section extends to the drain hole, and the plug is formed at this lower end. In other embodiments, the second flow channel of the scalp massage device is only on one side, either left or right. In other embodiments, the shape of the second attachment / detachment part of the scalp massage device is substantially cylindrical, and a notch, recess, depression, groove, etc., is formed in a part of it, creating a gap between it and the drain opening. This gap serves as a drainage channel. In other embodiments, hot and cold water is supplied directly to the head immersion device from a showerhead or other water supply device. That is, the hot and cold water does not pass through the scalp massage device. In other embodiments, the neck rest is not attached, and a neck rest portion equivalent in shape to the neck rest is formed on the side of the shampoo bowl, serving as a part corresponding to the neck rest. In other embodiments, the seating procedure follows the installation procedure.

[0069] Next, the water outlet section 18 will be described based on the drawings. Figures 38 to 44 show the water outlet section 18. Figures 38 to 40 show the external appearance of the water outlet section 18, and Figures 41 to 44 show a cross-section of the water outlet section 18.

[0070] Here, the water discharge section 18 is a component of the scalp massage device 10, 110, and the scalp massage device 10, 110 has the following configuration. The shower head 5 is connected to a connected part 11 attached to the shampoo bowl 1, a flow path 13 connected to the connected part 11 and extending upward, and a water discharge part 18 connected to the tip of the flow path 13. The water outlet 19 formed on the lower surface of the water discharge part 18 is U-shaped to match the hairline on the forehead of the person being treated 50, and hot water from the shower head 5 passes through the flow path 13 to the water discharge part 18 and is discharged from the water outlet 19. The hot and cold water discharged from the spout 19 flows continuously along the U-shape of the spout 19 until it hits the forehead of the person receiving treatment 50. Within the water outlet section 18, a series of interconnected layers are formed in the flow path. The connecting paths between floors are offset alternately on the upper and lower levels.

[0071] More specifically, as shown in Figures 38 to 40, the water outlet 18 is an elliptical or oblong three-dimensional object when viewed from above or below, with a flow path connection 200 at the top and a water outlet 19 at the bottom. The flow path connection 200 consists of a pair and is connected to the second tip 17 of the flow path 13 (see Figure 5). The water outlet 19 is U-shaped, following the hairline on the forehead of the person being treated 50, and continues in a U-shape linear manner toward the side. Note that the flow path connection may be a single unit. Also, the water outlet may consist of multiple holes arranged in a U-shape.

[0072] As shown in Figure 41, the water outlet 18 has a flow path inside, and the flow path has three layers connected vertically. More specifically, the flow path is realized by a cylindrical main flow path 201 connected to the flow path connection 200 from the inside of the water outlet 19, and a U-shaped layered flow path 202 connected to the lower end of the main flow path 201 and extending to the left and right, with the downstream side of the layered flow path 202 leading to the water outlet 19. The layered flow path 202 has two compartment pieces formed on the inside, and these first compartment piece 203 and second compartment piece 204 form three layers vertically. The number of layers may be two or four or more. The number of compartment pieces is determined according to the number of layers.

[0073] The layers consist of an upper layer channel 205 leading to the main channel section 201, a middle layer channel 206 leading downstream of the upper layer channel 205, a lower layer channel 207 leading downstream of the middle layer channel 206, a discharge outlet connecting passage 208 leading from the downstream side of the lower layer channel 207 to the discharge outlet 19, an upper-middle connecting passage 209 formed by the separation of the upper layer channel 205 and the middle layer channel 206 by a first partition piece 203, and a middle-lower connecting passage 210 formed by the separation of the middle layer channel 206 and the lower layer channel 207 by a second partition piece 204. The connecting passages 209 and 210 between the layers are offset alternately on the upper and lower sides. Specifically, because the first section piece 203 is formed to protrude towards the rear (to the right in Figure 41), the upper-middle connecting passage 209 leads to the rear of the upper layer channel 205 and the rear of the middle layer channel 206 (to the right in Figure 41). On the other hand, because the second section piece 204 is formed to protrude towards the front (to the left in Figure 41), the middle-lower connecting passage 210 leads to the front of the middle layer channel 206 and the front of the lower layer channel 207 (to the left in Figure 41). Therefore, the upper-middle connecting passage 209 and the middle-lower connecting passage 210 are offset from each other in the front-to-back direction. The channels meander in the front-to-back direction within the layered channel section 202.

[0074] The front-to-back width of each connecting passage 209, 210 between layers narrows as you go down to the lower layers. More specifically, the front-to-back width of the middle-to-lower connecting passage 210 shown in Figure 43 is narrower than the front-to-back width of the upper-to-middle connecting passage 209 shown in Figure 42, and the front-to-back width of the outlet connecting passage 208 shown in Figure 44 and the outlet 19 shown in Figure 40 are narrower than the front-to-back width of the middle-to-lower connecting passage 210. As shown in Figure 43, in the middle-to-lower connecting passage 210, the front-to-back width of the left and right lateral sections 212 is wider than the front-to-back width of the central section 211.

[0075] As described above, the water discharge section 18 is configured as described. Next, the effects of the water discharge section 18 will be explained along with its operation.

[0076] The hot and cold water supplied to the scalp massage devices 10 and 110 is discharged from the outlet 19 at the discharge section 18, via the main flow path 201 and the hierarchical flow path 202. In the hierarchical flow path 202, the hot and cold water meanders through the upper layer flow path 205, the upper-middle connecting passage 209, the middle layer flow path 206, the middle-lower connecting passage 210, the lower layer flow path 207, and the outlet connecting passage 208, and is discharged from the outlet 19 in a U-shape. The hot and cold water discharged from the outlet 19 continues uninterrupted along the U-shape of the outlet 19, like a wall of water, until it hits the forehead of the person receiving the treatment. In other words, the hot and cold water that continues uninterrupted along the U-shape of the outlet 19 resembles a curtain or a glass surface. In particular, in the central-lower connecting passage 210, the front-to-back width of the left and right lateral sections 212 is wider than the front-to-back width of the central section 211. As a result, the flow rate of hot and cold water is greater in the left and right lateral sections 212 than in the central section 211, creating a continuous U-shape without interruption.

[0077] The water flows onto the scalp and hairline of the person receiving treatment 50, and then down the hair towards the top of the head (see water flow 54 in Figure 34). The person receiving treatment 50 can relax as their scalp and hairline are moderately stimulated by the water from the spout 19. Meanwhile, the treatment continues even if the practitioner is performing other tasks. Therefore, the treatment is comfortable for the person receiving treatment 50, and the practitioner can perform other tasks without any interference. In particular, because the water flows continuously in a U-shape without interruption, the person receiving treatment 50 does not feel any discomfort. If the water flow were interrupted or released individually from multiple holes like a shower, the person receiving treatment 50 would be able to sense when the water flow is interrupted and hitting their scalp and hairline, which could cause discomfort and distractions that hinder relaxation.

[0078] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. Furthermore, various design modifications can be made to the present invention without departing from the matters described in the claims. [Explanation of Symbols]
