Description

TECHNICAL FIELD

[0001] The present application relates to a head bath device for a massage or the like of a head, and a shampoo basin provided with the head bath device. BACKGROUND

[0002] In the past, a shampoo basin for washing the hair of a subject has been provided in a hairdressing salon or the like. The subject places the head in the shampoo basin and is operated from the side or the top of the head by an operator. The operation in the shampoo basin is, for example, shampooing, head massage, or the like, and takes several tens of minutes to about one hour depending on the operation. In the case of a long operation, if the neck of the subject directly contacts the edge of the shampoo basin, the subject sometimes feels pain in the neck. Therefore, for example, a shampoo basin mounting type pillow (hereinafter, referred to as "the invention of the known document 1") described in the following Patent Document 1 is mounted to the edge of the shampoo basin, and a cushioning effect is achieved to avoid the neck of the subject directly contacting the edge of the shampoo basin.

[0003] On the other hand, the operator undertakes many services in addition to the operation, such as cleaning, maintenance of tools, answering the phone, and confirmation of a reservation, for example. However, if the operator is restrained by the operation for a long time, the operator cannot perform other services during this period. Therefore, an operation that is comfortable for the subject and does not hinder the operator from performing other services is required. As such an operation, for example, continuously pouring hot water on the head of the subject, and continuously immersing the head in the hot water (hereinafter, referred to as "head bath") can be considered.

[0020] The head bathing device of the present application is characterized in that the water flow portion has a configured portion in which the neck portion is configured, by being cut toward the lower side of the water flow portion.

[0021] To achieve the above object, the hair washing basin of the present application is characterized by having the above head bathing device.

[0022] Effects of the Invention

[0023] The head bathing device of the present application has a bottom portion configured at a position higher than the bottom surface of the hair washing basin operated by the operator, and a peripheral side portion connected to the peripheral edge of the bottom portion and extending toward the upper side, the peripheral side portion having a neck edge portion, which is a portion opposite to the neck portion placement portion in which the neck of the operator is placed at the side edge of the hair washing basin, and the head bathing device accumulates hot water for soaking the head of the operator. That is, in the hair washing basin, hot water is accumulated in the head bathing device. Since the neck edge portion of the head bathing device is opposite to the neck portion placement portion of the hair washing basin, if the operator places the neck in the neck portion placement portion, the head is soaked in the hot water. During this period, the operator can relax by soaking the head in the hot water, and in addition, the hair is soaked in the hot water together with the head, so that dirt of the hair falls off. On the other hand, even if the operator performs other business, the operation continues. Therefore, an operation comfortable for the operator and not obstructive even if the operator performs other business can be performed. In addition, since the bottom portion is configured at a position higher than the bottom surface of the hair washing basin, a small amount of hot water is sufficient compared to the case where hot water is directly accumulated in the hair washing basin.

[0024] The head bathing device of the present application can soak the back of the head of the operator when the water is full. That is, the back of the head of the operator is soaked in the hot water, and the operator is relaxed. Therefore, an operation comfortable for the operator and not obstructive even if the operator performs other business can be performed.

[0025] In the head bathing device of the present application, the neck edge portion is opposite to the neck of the operator without contacting the neck of the operator. With this structure, hot water can flow between the neck portion placement portion and the neck. The operator can relax by the hot water continuously flowing behind the neck. In addition, by continuously flowing the hot water, the operation continues, so that an operation comfortable for the operator and not obstructive even if the operator performs other business can be performed.

[0026] The head bathing device of the present application has a foot portion abutting against the bottom surface. Therefore, it can be stably disposed in the hair washing basin.

[0027] The head bathing device of the present application has a foot portion hanging at the side edge. Therefore, it can be stably disposed in the hair washing basin.

[0028] The head bathing device of the present application has a foot portion that fits into a drain of a shampoo basin. Therefore, it can be stably set in the shampoo basin.

[0029] In the head bathing device of the present application, the neck rim portion has an opposite portion that opposes the neck of the operator and water flow portions that are cut out from the opposite portion on both sides thereof toward the lower side. With this structure, when hot water is accumulated and the water level rises, the hot water flows from the water flow portions on both sides of the opposite portion before the water level reaches the opposite portion. That is, the hot water continuously flows behind the neck of the operator. Therefore, the operator can be relaxed.

[0030] The head bathing device of the present application has a tub main portion that has a bottom portion and a peripheral portion, and a gap is formed by cutting out a portion opposite the neck rest portion; and a neck rim portion that is attached to and detached from the gap, the neck rim portion having an opposite portion that opposes the neck of the operator, water flow portions that are cut out from the opposite portion on both sides thereof toward the lower side, and guide portions that are formed on both sides of the water flow portions and extend upward, and the front end portions thereof project toward each other. With this structure, various shapes and sizes of the neck rim portion can be used according to the type of operation and the size of the operator. In addition, the hot water flows from the guide portions to the front end portions due to the momentum of the flow, and at the front end portions, the flow is continued toward the back of the neck of the operator. Therefore, the operator can be relaxed.

[0031] The head bathing device of the present application has groove portions that are cut out from the water flow portions on both sides thereof toward the bottom portion shallower than the water flow portions. Therefore, even in the case where the size of the operator is large and the water flow portions are blocked by the back of the neck, and the flow of the hot water from the water flow portions is hindered, the hot water can be made to flow to the back of the neck of the operator with a large size by making the hot water flow from the groove portions.

[0032] In the head bathing device of the present application, the water flow portions have configured portions in which the neck rest portion is disposed by being cut out from the water flow portions toward the lower side. That is, even in the case where the shampoo basin is provided with the neck rest portion, by disposing the neck rest portion in the configured portions, the neck rest portion does not interfere with the water flow portions. The hot water flows from the neck rest portion, and continuously flows behind the neck of the operator. Therefore, the operator can be relaxed.

[0033] The shampoo basin of the present application has the head bathing device. Therefore, the same effects as the above-described head bathing device are exerted. BRIEF DESCRIPTION OF DRAWINGS

[0078] The following is a description of the shampoo basin and head bath device according to embodiments of the present invention. The shampoo basin is equipped with a scalp massage device, a head bath device, and other operating devices for operation. Figure 1 and Figure 2 The appearance of shampoo basin 1 is shown. Figure 3 The image shows the scalp massage device 10 installed in the shampoo basin 1. Figure 4 The image shows the scalp massage device 10 and the head bath device 25 installed in the shampoo basin 1. Furthermore, in... Figure 1 In this case, the depth direction of the shampoo basin 1 is set as up and down, the top of the head of the person being operated 50 when the head is placed in the shampoo basin 1 is set as the back, the neck side which is the opposite side is set as the front, and the horizontal width direction is set as the side (left side, right side).

[0079] like Figure 1 and Figure 2 As shown, the shampoo basin 1 is used to allow the person being treated 50 to place their head in a supine position on a barber chair or similar work surface (not shown) to receive treatment (see reference). Figure 32 Operations include, for example, shampooing, scalp massage, hair dyeing, perming, and eye makeup. The shampoo basin 1 is, for example, a roughly hemispherical basin consisting of a bottom surface 2 and a side surface 3. A cylindrical drain outlet 4 is formed on the bottom surface 2, and a spray nozzle 5 for supplying hot water and a hot water stop valve 6 are provided on the inner side 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 support 7, serving as a neck support for the neck of the person being operated on, is installed thereon. The neck support 7 consists of a first support portion 8 connected to the side surface 3 and a hemispherical second support portion 9 positioned rearward of the first support portion 8. The second support portion 9 consists of a pair of left and right sides. The neck of the person being operated on is supported on the first support portion 8, and the back of the neck, the hairline, the neck, and the hairline (hereinafter referred to as "back of the neck") of the person being operated on are supported on the second support portion 9.

[0080] like Figure 3 and Figure 4As shown, the shampoo basin 1 is equipped with a scalp massage device 10 and a head bath device 25, depending on the type of operation. Here, the scalp massage device 10 and the head bath device 25 are described based on the accompanying drawings. Figure 5 to Figure 10 The appearance of the scalp massage device 10 is shown. Figure 11 to Figure 15 The appearance of the scalp massage device 10 installed in the shampoo basin 1 is shown. Figure 16 to Figure 25 The appearance of the head bath device 25 is shown. Figure 26 to Figure 31 The appearance and cross-section of the head bath device 25 installed in the shampoo basin 1 are shown.

[0081] like Figure 5 to Figure 10 As shown, the scalp massage device 10 includes a connecting portion 11 for connecting a nozzle 5, a flow path portion 13 connected to the connecting portion 11, a water outlet portion 18 connected to the flow path portion 13, and a mounting portion 20 connected to the flow path portion 13 and mounted on the shampoo basin 1. The connecting portion 11 is a cylindrical shape extending vertically, with an opening 12 at the top and a lower portion connected to the flow path portion 13. The opening 12 has a mounting and fixing mechanism (not shown) for fixing the nozzle 5. The mounting and fixing mechanism may include, for example, a structure that uses a rope or strap to bind the nozzle 5, a head bath device 25 that acts as a counterweight for pressing the nozzle 5 from above, a threaded structure in which the opening 12 and the nozzle 5 are threaded together, a mechanical fit, and the selection of a material for generating friction between the opening 12 and the nozzle 5 by making the opening 12 rubber or similar materials.

[0082] 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 a first front end portion 15, which is the front end of the first flow path section 14. The inner side of each flow path section 14, 16 is hollow, and a flow path is formed therein. The first flow path section 14 is composed of a pair of left and right sections centered on the connected section 11. The first flow path section 14 extends from the connected section 11 to the left and right and bends or folds forward, with the first front end portion 15 facing upward. The first front end portion 15 has a hinge portion 23 and a shaft support portion 24. The hinge portion 23 allows the second flow path section 16 to rotate and also allows the second flow path section 16 to move back and forth, connecting the second flow path section 16 via the hinge portion 23. The hinge portion 23 has a limiting portion (not shown) for defining the movable area of ​​the second flow path section 16. The shaft support portion 24 is a groove formed at the rear of each first front end portion 15, used when mounting the head immersion device 25 (see reference). Figure 31 ).

[0083] The second flow path section 16 extends upward from the first front end section 15 on the left and right sides and bends or folds laterally, connecting at the second front end section 17, which serves as the front end. The second front end section 17 is connected to a water outlet section 18 at its lower part. The water outlet 19 of the water outlet section 18 faces downwards from where the shampoo basin 1 is located. The mounting and dismounting section 20 has a first mounting and dismounting section 21 that abuts against the bottom surface 2 of the shampoo basin 1 and a second mounting and dismounting section 22 that connects to the drain outlet 4 of the shampoo basin 1. The first mounting and dismounting section 21 protrudes downward from the first front end section 15, and its length is adjusted by a threaded structure or the like. The second mounting and dismounting section 22 is plate-shaped and protrudes downward from the first flow path section 14 directly below the connected section 11. The second mounting and dismounting section 22 may be made of, for example, rubber or silicone.

[0084] like Figure 11 to Figure 15 As shown, the scalp massage device 10 is installed in the shampoo basin 1. Specifically, the second detachable part 22 of the scalp massage device 10 is inserted into the drain outlet 4 of the shampoo basin 1, and the side of the second detachable part 22 contacts the inner surface of the drain outlet 4, thereby engaging the second detachable part 22 with the drain outlet 4 (see reference). Figure 30 and Figure 31 The drain outlet 4 is cylindrical, while the second mounting / unmounting part 22 is plate-shaped, thus creating a gap between the second mounting / unmounting part 22 and the drain outlet 4. Hot water drains through this gap from the drain outlet 4. The first mounting / unmounting part 21 abuts against the bottom surface 2 of the shampoo basin 1, supporting each flow path part 14, 16. Therefore, each flow path part 14, 16 is supported at three points by each mounting / unmounting part 21, 22. Furthermore, during use, the nozzle 5 of the shampoo basin 1 is connected to the connected part 11 (see reference). Figure 30 ).

[0085] like Figure 15 As shown, the second flow path 16 changes angle relative to the first flow path 14 via the hinge 23. That is, the second flow path 16 tilts rearward. The hinge 23 has a limiting portion, thus limiting the movable area and preventing changes in angle beyond a predetermined range. For the predetermined angle, when the orientation of the second flow path 16 is set to zero degrees (vertical), for example, it is 25 to 35 degrees rearward, preferably around 30 degrees, and 5 to 15 degrees forward, preferably around 10 degrees. If the movable area is too large, when the scalp massage device 10 is installed in the shampoo basin 1, it may sometimes come into contact with the side 3 of the shampoo basin 1, hindering the installation operation.

[0086] The second flow path section 16 can move in the front-to-back direction via the hinge section 23. That is, the position of the shaft itself changes when the second flow path section 16 rotates.

[0087] like Figure 16 to Figure 25 As shown, the head bath device 25 is, for example, a barrel-shaped device that is slightly narrowed into a funnel, similar to a washbasin, and has a barrel body 26 and a flow-rectifying part 40 as a neck edge. Here,Figure 16 to Figure 20 This shows the state before the rectifier 40 is installed on the barrel body 26. Figure 21 to Figure 25 The diagram shows the state in which the rectifier 40, as a head bath device 25, is installed on the barrel body 26. The barrel body 26 has a bottom 27 and a peripheral side portion 28 connected to the periphery of the bottom 27 and extending upward. The bottom 27 is formed with a different height, and a portion of the peripheral side portion 28 is cut out. By forming the bottom 27 with a different height, a recessed space 29 is formed on the outer side of the inner side of the bottom 27. That is, a bottom side portion 30 extending upward is connected to the inner side of the bottom 27, and a stepped bottom 31 is connected to the inner side of the bottom side portion 30. A plurality of feet 32 ​​for self-standing are formed on the lower surface of the bottom 27. Furthermore, the number, shape, length, position, etc., of the feet 32 ​​are arbitrary. A drain hole 33 is formed approximately in the center of the bottom 27. A plug 34 is attached to and detached from the drain hole 33 (see reference). Figure 30 ).

[0088] A neck edge gap 48 is formed by cutting a notch near the front side of the peripheral side portion 28, opposite to the neck support member 7. The rectifier part 40 is installed or removed through this neck edge gap 48. A shaft protrusion 36 is formed on the outer surface of the peripheral side portion 28, excluding the neck edge gap 48. The shaft protrusion 36 consists of a pair of left and right protrusions laterally at a position closer to the front side than the bottom side portion 30. A pair of grooves 38 are formed near the upper edge of the outer edge portion 35, near the neck edge gap 48, which is near the front side. A plurality of small holes 39 are formed near the neck edge gap 48 in the outer edge portion 35, following the shape of the neck edge gap 48.

[0089] The rectifier 40 is a thin sheet made of materials such as rubber, silicone, or polyurethane. It is fixed to the peripheral side portion 28 of the main body portion 26 by a fixing member 47, serving as a neck rim portion. The fixing member 47 is shaped along the neck rim gap 48, clamping the rectifier 40 between the fixing member 47 and the peripheral side portion 28 and fixing it by screws or the like. The rectifier 40 has a peripheral main body portion 41 fixed to the peripheral side portion 28, a corresponding portion 42 connected to the upper part of the peripheral main body portion 41, a water flow portion 43 formed by cutting open the left and right sides of the corresponding portion 42, and guide portions 45 formed on the left and right sides of the water flow portion 43. The corresponding portion 42 protrudes upward from the center of the upper end of the peripheral main body portion 41. The left and right sides of the corresponding portion 42 are cut downward toward the peripheral main body portion 41, so that the water flow portion 43 is formed at a position lower than the corresponding portion 42. The water flow section 43 is further cut downward toward the peripheral main body section 41 to form the placement section 44. The placement section 44 is fitted with the second placement section 9 of the neck support member 7 (see reference). Figure 26The guide portion 45 extends upward from the upper end of the peripheral main body portion 41, and the guide front portion 46, which serves as the front end portion, extends in a direction of approaching each other. In relation to the flow rectifying portion 40, the groove portion 38 is positioned along the circumference of the outer edge portion 35 at a position further outward than the disposed portion 44 (water flow portion 43) and the guide front portion 46. Furthermore, it is cut shallower than the water flow portion 43 from the outer edge portion 35 toward the bottom 27.

[0090] like Figure 26 to Figure 31 As shown, the head bath device 25 is installed on a shampoo basin 1 on which a scalp massage device 10 is installed. The connecting part 11 of the scalp massage device 10 is connected to the nozzle 5 of the shampoo basin 1, and the stepped bottom 31 of the head bath device 25 rests on the nozzle 5. That is, the head bath device 25 serves as the mounting and dismounting mechanism for the scalp massage device 10. In addition, the mounting and dismounting mechanism can also be implemented by using it in conjunction with a rope or strap. The axle protrusion 36 of the head bath device 25 is engaged with the shaft support part 24 of the scalp massage device 10. On the other hand, the flow straightening part 40 of the head bath device 25 is installed on the second mounting part 9 of the neck support member 7. That is, the second mounting part 9 is embedded in the disposed part 44 of the flow straightening part 40, the disposed part 44 is closed, and the second mounting part 9 replaces the water flow part 43. The opposing parts 42 of the flow straightening part 40 are embedded between the second mounting parts 9. The guide part 45 is embedded along the outer periphery of the second mounting part 9. The rectifier 40 is opposite to the first mounting part 8 of the neck support 7. The bottom 27 of the head bath device 25 is positioned above the bottom surface 2 of the shampoo basin 1, and a plug 34 is installed in the drain hole 33 of the bottom 27.

[0091] As described above, a scalp massage device 10 and a head bath device 25 are constructed.

[0092] The effects of this embodiment will now be explained together with its functions. Figure 32 to Figure 34 The operation based on this embodiment is shown.

[0093] like Figure 32 to Figure 34 As shown, the person being operated on, 50, lies supine with their head placed in the shampoo basin 1. At this time, the neck of the person being operated on, 50, rests on the first resting part 8 of the neck resting member 7. Furthermore, the back of the neck and other parts of the person being operated on, rest on the second resting part 9. The hair of the person being operated on, 50, is wetted with hot water from the spray nozzle 5 before operation. By pre-wetting the hair, the hot water is prevented from bouncing back onto the hair during operation. If the operation is performed with dry hair, the hot water sprayed from the scalp massage device 10 may sometimes hit the hair and bounce back, splashing onto the face and clothes of the person being operated on, 50.

[0094] With the head of the user 50 placed on the shampoo basin 1, the scalp massage device 10 is installed in the shampoo basin 1. The second flow path 16 of the scalp massage device 10 is installed in a backward tilted position. By tilting the second flow path 16 backward, the scalp massage device 10 is installed in the shampoo basin 1 so that the water outlet 18 is not facing the face of the user 50. If the scalp massage device 10 is installed in the shampoo basin 1 with the second flow path 16 in a vertical position, hot water remaining in the water outlet 18 may sometimes splash onto the face and clothes of the user 50 during other operations.

[0095] The nozzle 5 is connected to the connecting part 11 of the scalp massage device 10. If the mounting and detaching mechanism is, for example, a strap, the nozzle 5 is attached to the connecting part 11. The head bath device 25 is positioned below the back of the head, mounted on the scalp massage device 10, and placed on top of the nozzle 5. By mounting the head bath device 25 to the scalp massage device 10, a mounting and detaching mechanism that can be used in conjunction with a strap or the like is achieved. Furthermore, when the head bath device 25 is positioned below the back of the head, if the user 50 has long hair, the user 50's head is lifted, and all the hair is tucked inside the head bath device 25.

[0096] With the shampoo basin 1 containing the head of the person being operated on (50) equipped with the scalp massage device 10 and the head bath device 25, the second flow path 16 of the scalp massage device 10 remains tilted backward, thus it is positioned on the top of the head of the person being operated on (50) and does not face the scalp or hairline. On the other hand, the opposing part 42 of the head bath device 25 faces the back of the neck of the person being operated on (50). At this time, the opposing part 42 does not contact the back of the neck, leaving a slight gap between the back of the neck and the opposing part 42. Furthermore, the placement of the neck, back of the neck, etc., on each of the mounting parts 7 and 8 varies slightly depending on the body size of the person being operated on (50).

[0097] When the stop valve 6 of the shampoo basin 1 is operated to supply hot water, hot water is sprayed out from the nozzle 5. Since the nozzle 5 is connected to the connection part 11 of the scalp massage device 10, hot water is sprayed out from the connection part 11 through the first flow path 14 and the second flow path 16 and then sprayed out from the outlet 19 of the outlet part 18. The sprayed hot water does not splash onto the head of the user 50 but accumulates in the head bath device 25. As the water level gradually rises from the bottom 27 of the head bath device 25, the back of the head is moderately immersed in the hot water. When the water level reaches the second placement part 9 of the neck support 7, the hot water meanders left and right along the second placement part 9 (see reference). Figure 33 The water flow (51) overflows from the left and right sides of the second mounting section 9 towards the outside of the head bath device 25 (see reference). Figure 34(Water flow 52). At this time, the hot water will not flow beyond the opposite part 42. Since the back of the neck of the person being operated on is placed on the second placement part 9, the hot water flows along the second placement part 9 and over the back of the neck. The back of the neck is not immersed in still water, but is placed in continuously flowing hot water, so the person being operated on will not be insensitive at the back of the neck, and can feel the water flow and relax.

[0098] Due to the momentum of the hot water flow, the hot water also flows from the second mounting part 9 to the guide part 45, and from the front end 46 of the guide towards the rear neck, etc. (see reference) Figure 33 (Water flow 53). Hot water flows appropriately towards the back of the neck, etc., thus enabling the person being treated to relax 50.

[0099] When the water level reaches the second mounting section 9, the water will be full. When the water is full, the back of the head of the person being operated on 50 is immersed in hot water, thus allowing the person being operated on 50 to relax. In addition, the hair is immersed in hot water along with the head, thereby removing dirt from the hair.

[0100] After the back of the head is moderately immersed in hot water, or after the hot water overflows from the left and right sides of the second mounting section 9 towards the outside of the head bath device 25, adjust the angle of the second flow path section 16 so that it is positioned where the hot water sprayed from the outlet 19 reaches the scalp and hairline. The hot water reaches the scalp and hairline, flowing along the hair towards the top of the head (see reference). Figure 34 (Water flow 54). After the person 50 immerses the back of their head in hot water, or after placing the back of their neck in hot water, the scalp and hairline are moderately stimulated by the hot water from the outlet 19, so that they can appropriately feel the water flow in the back of their neck. If the hot water from the outlet 19 accumulates in the head bath device 25 while pouring onto the scalp and hairline, the scalp and hairline are stimulated before the back of the neck is placed in hot water, and sometimes the sensation in the back of the neck of the person 50 becomes weaker.

[0101] During operation, the person being operated on, 50, has their head immersed in hot water as described above, with the hot water flowing over the back of their neck, allowing them to relax. Furthermore, the operation continues even if the operator is engaged in other activities. Therefore, it allows for an operation that is comfortable for the person being operated on, 50, and does not interfere with the operator's other activities. Moreover, even when the operator is operating the device, since the scalp massage device 10 functions as a shower, the operator does not need to hold the showerhead 5 and can operate it with both hands.

[0102] Additionally, the bottom 27 of the head bath device 25 is positioned at a height higher than the bottom surface 2 of the shampoo basin 1 (see reference). Figure 34 Therefore, a small amount of hot water is sufficient compared to the case of directly accumulating hot water in the shampoo basin 1.

[0103] In this embodiment, the second mounting portion 9 of the neck support 7 is embedded in the disposed portion 44 of the rectifier portion 40 in the head bath device 25 (see reference). Figure 26 That is, even when the shampoo basin 1 is equipped with the neck support 7, the second support 9 will not interfere with the rectifier 40 by placing the second support 9 on the configured part 44.

[0104] When the operation is finished, operate the stop valve 6 to shut off the hot water. The second flow path 16 tilts backward and is positioned so as not to be opposite the head of the person being operated on 50. Therefore, even if hot water remaining in the flow path 13 drips from the outlet 19, it can prevent hot water from reaching the head.

[0105] In this embodiment, a drain hole 33 is formed at the bottom 27 of the head bath device 25, and a plug 34 is installed thereon (see reference). Figure 30 Therefore, by pulling out the plug 34, water can be drained from the drain hole 33.

[0106] The head bath device 25 is detached from the scalp massage device 10. The nozzle 5 is detached from the scalp massage device 10. The user's wet hair is moistened using a towel or other fibrous component.

[0107] In this embodiment, the rectifier 40 of the head bath device 25 is mounted and dismounted via the fixing member 47 (see reference). Figure 16 to Figure 25 Therefore, the rectifier 40 of various shapes can be installed and removed depending on the type of operation and the size of the operator 50. In addition, the rectifier 40 is a thin plate made of rubber, silicone, polyurethane, etc., so it is easy to deform and easy to replace.

[0108] In this embodiment, a pair of grooves 38 are formed on the upper edge of the outer edge 35 of the head bath device 25 and near the neck edge gap 48 on the near front side (see reference). Figure 22 The groove 38 is positioned circumferentially along the outer edge 35, further outward than the placement part 44 (water flow part 43) and the guide front part 46. Furthermore, the groove 38 has a shallower cut from the outer edge 35 towards the bottom 27 than the water flow part 43. If the person being operated on 50 is large and the opposing part 42 of the head bath device 25 contacts the back of the person's neck, the second placement part 9 may be blocked by the back of the neck, hindering the flow of hot water. In this case, hot water flows from the groove 38, which is shallower than the water flow part 43, thereby allowing hot water to reach the back of the neck of the larger person being operated on 50.

[0109] Furthermore, in other embodiments of the present invention, the head bath device 25 does not have a placement portion 44, but has a water flow portion 43 (see reference). Figure 21 and Figure 22In this case, the water level gradually rises from the bottom 27 of the head bath device 25, and when it reaches the water flow section 43, it overflows from the water flow section 43, which is lower than the opposing section 42, and flows towards the outside of the head bath device 25. At this time, since the opposing section 42 is formed to be higher than the water flow section 43, the hot water will not flow beyond the opposing section 42. The water flow section 43 is opposite to the back of the neck of the person being operated on, so the hot water flows over the back of the neck of the person being operated on. In this case, the second mounting section 9 may or may not be present.

[0110] The effects of the scalp massage device 10 used in this embodiment will now be explained.

[0111] The second flow path 16 of the scalp massage device 10 extends upward from the first front end 15 of the first flow path 14 and bends or folds laterally (see reference). Figure 7 Through this structure, the second flow path 16 will not interfere with the head of the operated object 50.

[0112] The first front end 15 of the scalp massage device 10 has a hinge portion 23, and the second flow path portion 16 changes angle relative to the first flow path portion 14 via the hinge portion 23 (see reference). Figure 15 This structure allows for a change in the position of the water outlet 18, enabling adjustment of the location where hot water sprayed from the outlet 19 reaches the scalp. Furthermore, it facilitates the installation of the shampoo basin 1.

[0113] Furthermore, the hinge portion 23 has a limiting portion for defining the movable area of ​​the second flow path portion 16. This structure limits the movable area of ​​the second flow path portion 16, preventing changes beyond a predetermined angle. Therefore, for example, hot water will not splash onto the face of the person being operated on 50.

[0114] The second flow path section 16 can move in the front-to-back direction via the hinge section 23. Therefore, the second flow path section 16 is appropriately configured according to the position of the hairline of the person being operated on 50.

[0115] The following describes a modified version of the scalp massage device 10 based on the accompanying drawings. Figure 35 to Figure 37 A modified example of a scalp massage device 110 is shown. Figure 35 and Figure 36 The appearance of the scalp massage device 110 is shown. Figure 37 The enlarged view shows a cross-section of the scalp massage device 110 with its second attachment / removal part 122 inserted into the drain outlet 4 of the shampoo basin 1. Furthermore, the following description will primarily focus on structures different from the scalp massage device 10; structures identical to the scalp massage device 10 will be labeled with the same reference numerals and will be omitted from the description.

[0116] like Figure 35 and Figure 36As shown, the second mounting / unmounting portion 122 of the scalp massage device 110 has a pair of flange portions 155 protruding from the lower portion of the near-frontal and inner sides toward the near-frontal and inner sides. The flange portions 155 are generally semi-circular when viewed from above. When viewed from the side, the flange portions 155 have a flat upper surface portion 156 as the upper surface and an inclined lower surface portion 157 as the lower surface. The flat upper surface portion 156 is a flat semi-circular plate, and the inclined lower surface portion 157 gradually slopes downwards from the outer front end toward the second mounting / unmounting portion 122.

[0117] like Figure 37 As shown, when the second loading / unloading part 122 is inserted into the drain outlet 4 of the shampoo basin 1, the flange 155 is positioned deeper than the upper end of the opening of the drain outlet 4 and spaced apart from the inner surface of the drain outlet 4. Hot water discharged from the drain outlet 4 passes through a mesh hair collector (not shown) installed in the drain outlet 4. At this time, the hot water flows from the flat upper surface part 156 down the inclined lower surface part 157 towards the bottom of the drain outlet 4. That is, the flowing hot water collides with the hair collector, which sometimes produces an unpleasant sound for the user 50. In this case, by draining the hot water through the flange 155, the position where the hot water begins 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 basin 1. Therefore, the distance from the position where the hot water begins to fall to the collision with the hair collector is also shortened. Therefore, compared with the case where the hot water falls from the bottom surface 2 without the flange 155, a noise reduction effect can be achieved, and the user 50 will not feel an unpleasant sound and can relax.

[0118] Furthermore, in other embodiments of the invention, only the head bath device is installed in the shampoo basin. In this case, the feet of the head bath device are elongated and stand upright on the bottom of the shampoo basin. Additionally, instead of a scalp massage device, a platform is provided on the shampoo basin, and the head bath device is placed on this platform. Even without a scalp massage device, as long as it is a head bath, the operator can operate it with both hands, even when the operator is performing the operation, which is therefore preferable.

[0119] In other embodiments, the feet are hook-shaped and are designed to hang on the side edge of the shampoo basin.

[0120] In other embodiments, the foot is shaped to fit into the drain outlet of the shampoo basin, for example, it has the same structure as the second detachable part of a scalp massage device.

[0121] Other implementations do not have feet.

[0122] In other embodiments, the opposing part makes slight contact with the back of the neck or other parts of the person being operated on.

[0123] Other embodiments do not have a water flow section.

[0124] In other embodiments, instead of a rectifier portion, a neck edge portion with the same shape as the rectifier portion is formed in the main body of the barrel.

[0125] Other embodiments do not have a groove.

[0126] In other embodiments, the plug is integrated with the rectifier. That is, the lower end of the rectifier extends to the drain hole, and a plug is formed at the lower end.

[0127] In other embodiments, the second flow path of the scalp massage device is only on one side (left or right).

[0128] In other embodiments, the second detachable part of the scalp massage device is generally cylindrical in shape, and a portion thereof has cuts, recesses, depressions, grooves, etc., that create a gap between it and the drain outlet. This gap serves as a drainage path.

[0129] In other embodiments, hot water is supplied directly to the head bath device from a showerhead or other water supply appliance. That is, the hot water does not pass through the scalp massage device.

[0130] In other embodiments, no neck support is installed; instead, a neck support portion with the same shape as the neck support is formed on the side of the shampoo basin, which is equivalent to the neck support.

[0131] The water outlet section 18 will now be described based on the accompanying drawings. Figure 38 to Figure 44 The water outlet section 18 is shown. Figure 38 to Figure 40 The appearance of the water outlet 18 is shown. Figure 41 to Figure 44 The cross-section of the water outlet 18 is shown.

[0132] Here, the water outlet 18 is a component constituting the scalp massage device 10, 110, which has the following structure.

[0133] It has a connected part 11 that is installed on the shampoo basin 1 and connected to the nozzle 5, a flow path part 13 that is connected to the connected part 11 and extends upward, and a water outlet part 18 that is connected to the front end of the flow path part 13. The water outlet 19 formed on the lower surface of the water outlet part 18 is U-shaped, imitating the hairline of the hair on the forehead of the user 50. Hot water from the nozzle 5 reaches the water outlet part 18 through the flow path part 13 and is sprayed out from the water outlet 19.

[0134] The hot water sprayed from the outlet 19 continuously along the U-shape of the outlet 19 until it reaches the forehead of the person being operated on 50.

[0135] The flow path within the water outlet section 18 forms interconnected tiers.

[0136] The pathways connecting different social strata are staggered on the upper and lower sides.

[0137] If detailed explanation is required, such as Figure 38 to 40 As shown, the water outlet 18 is a three-dimensional object that appears elliptical or oblong when viewed from above or below. It has a flow path connection 200 at the top and a water outlet 19 on its lower surface. The flow path connection 200 consists of a pair and is connected to the second front end 17 of the flow path 13 (see reference). Figure 5 The water outlet 19 is a U-shaped structure modeled after the hairline on the forehead of the person being operated on 50, forming a continuous U-shaped line facing to the side. Alternatively, the flow path connection can be a single unit. Another option is that the water outlet can consist of multiple holes arranged in a U-shape.

[0138] like Figure 41 As shown, the water outlet 18 has an internal flow path, in which three interconnected tiers are formed. In detail, the flow path is formed 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 tiered flow path 202 connected to the lower end of the main flow path 201 and extending to the left and right. The downstream side of the tiered flow path 202 communicates with the water outlet 19. The tiered flow path 202 has two dividing plates formed on its inner side, and the three tiers are formed by the first dividing plate 203 and the second dividing plate 204. Furthermore, the number of tiers can be two or more. The number of dividing plates depends on the number of tiers.

[0139] The flow stages include: an upper flow path 205 connected to the main flow path 201; a middle flow path 206 connected to the downstream side of the upper flow path 205; a lower flow path 207 connected to the downstream side of the middle flow path 206; an outlet connecting path 208 connecting the lower flow path 207 to the outlet 19; an upper-middle connecting path 209 formed by a first dividing plate 203 between the upper flow path 205 and the middle flow path 206; and a middle-lower connecting path 210 formed by a second dividing plate 204 between the middle flow path 206 and the lower flow path 207. The connecting paths 209 and 210 of each flow stage are staggered on the upper and lower sides. That is, the first dividing plate 203 faces rearward (in...). Figure 41 The middle section extends outwards (to the right), thus forming the upper middle connecting path 209 and the rear part of the upper layer flow path 205 and the rear part of the middle layer flow path 206 (in the middle layer flow path 206). Figure 41 (Middle to right) connected, on the other hand, the second dividing piece 204 faces forward (in) Figure 41 It extends outwards (to the left) to form, thereby connecting the lower and middle connecting path 210 with the front part of the middle layer flow path 206 and the front part of the lower layer flow path 207 (in Figure 41 (Middle to left) connection. Therefore, the upper middle connection path 209 and the middle lower connection path 210 are staggered. The flow path curves back and forth within the hierarchical flow path section 202.

[0140] The widths of the connecting paths 209 and 210 between different levels narrow as they descend to the next level. For a more detailed explanation... Figure 43 The front and rear widths of the middle and lower connecting path 210 shown are formed as... Figure 42 The front and rear widths of the upper-middle connecting path 209 shown are narrow. Figure 44 The front and rear widths of the outlet connecting path 208 shown are as follows: Figure 40 The front and rear width of the outlet 19 shown is narrower than the front and rear width of the middle and lower connecting passage 210. For example... Figure 43 As shown, in the lower middle connecting path 210, the front-to-back width of the left and right side portions 212 is wider than the front-to-back width of the central portion 211.

[0141] As described above, the water outlet section 18 is constructed. The effects of the water outlet section 18 will now be explained along with its function.

[0142] Hot water supplied to the scalp massage devices 10 and 110 flows through the main flow path 201 and the tiered flow path 202 in the water outlet section 18, and is then sprayed out from the water outlet 19. In the tiered flow path 202, the hot water meanders through the upper flow path 205, the upper-middle connecting path 209, the middle flow path 206, the middle-lower connecting path 210, the lower flow path 207, and the water outlet connecting path 208, and is then sprayed out from the water outlet 19 in a U-shape. The hot water sprayed from the water outlet 19 flows continuously along the U-shape of the water outlet 19 from the water outlet 19 until it reaches the forehead of the person being massaged, like a water wall. In other words, the continuous hot water flowing along the U-shape of the water outlet 19 is like a curtain or a glass surface. In particular, in the middle and lower connecting passage 210, the front and back widths of the left and right side portions 212 are wider than the front and back widths of the central portion 211. Therefore, the flow rate of hot water in the left and right side portions 212 is greater than that in the central portion 211, forming an uninterrupted and continuous U-shape.

[0143] Hot water is poured onto the scalp and hairline of the person being treated, flowing down the hair towards the top of the head (see reference). Figure 34 The hot water from the outlet 19 moderately stimulates the scalp and hairline of the person being operated on (54). Furthermore, the operation continues even if the operator is engaged in other activities. Therefore, an operation that is comfortable for the person being operated on (50) and does not interfere with other activities is possible. In particular, the hot water flows continuously in a U-shape without interruption, so the person being operated on (50) does not feel any discomfort. However, if the hot water is interrupted or sprays from multiple nozzles like a shower, the person being operated on (50) can feel the interruption of hot water flowing onto their scalp and hairline, which may sometimes cause discomfort and distracting thoughts that hinder relaxation.

[0144] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments. Moreover, various design changes can be made to the present invention without departing from the scope of the claims.
