The present invention relates to a shower head that can be used for massage in addition to the shower function.

As a shower head of this kind, there is one described in Patent Document 1. The shower head of Patent Document 1 rotates a rotating fin by the pressure of water supply at the time of watering, and converts the rotational force of the rotating fin into vibration so that a massage function by vibration can be obtained.

Japanese Unexamined Patent Publication No. 2018-75070

Therefore, the shower head of Patent Document 1 requires various movable parts such as a rotating fin and a conversion mechanism for converting the rotation of the rotating fin into vibration, which complicates the configuration and may cause a failure.

Further, since the massage action depends on the vibration based on the water supply pressure, if the vibration-applied portion is strongly pressed against the body surface portion, the vibration may be blocked and the massage may become impossible.
The present invention is to provide a shower head that has an effective massage function but can simplify the configuration.

In order to achieve the above object, the shower head of the present invention is characterized in that a rotating body for massage, which is rotated about an axis, is provided on the outer surface.
In the shower head configured as described above, a complicated movable mechanism becomes unnecessary, and the configuration can be simplified. When using the shower head, the rotating body is applied to the surface of the body to press the surface of the body, or the rotating body is rotated and moved on the surface of the body, so that the rotating body presses the surface of the body. It is possible to massage the body or massage it like kneading, and an effective massage effect can be obtained.

As described above, according to the present invention, since the rotating body for massage is supported on the outer surface of the shower head by a shaft, the configuration can be simplified even though an effective massage effect can be obtained. effective.

Hereinafter, the first embodiment of the shower head embodying the present invention will be described with reference to the drawings of FIGS. 1 to 7.

As shown in FIGS. 1 and 2, the shower head 11 of the present embodiment has a cylindrical handle 12 and a head body 13 detachably attached to the tip of the handle 12. A water supply hose 14 is connected to the base end of the handle 12, and the handle 12 constitutes a water supply channel from the water supply hose 14.

As shown in FIGS. 2 and 3, the inner peripheral surface of the tip of the handle 12 has a diameter-expanded portion 15 and a pair of open portions 16 that communicate with the diameter-expanded portion 15 and are located at intervals of 180 degrees. , A spiral groove 17 extending from the open portion 16 is formed. A small diameter portion 19 protruding through the step 18 is formed at the base end of the head main body 13, and protrusions 20 located at intervals of 180 degrees are formed on the outer periphery of the small diameter portion 19. Then, when the protrusion 20 enters the spiral groove 17 from the open portion 16, the head body 13 is rotated and attached to the tip of the handle 12. Further, the protrusion 20 is pulled out from the spiral groove 17 via the opening portion 16, so that the head body 13 is rotated and removed from the handle 12. In this case, the shape of the spiral groove 17 and the protrusion 20 so that the head body 13 can be attached and detached by rotating the head body 13 with respect to the handle 12 at a rotation angle of less than one rotation (about 90 degrees in the embodiment). Etc. are set. A seal ring 21 for maintaining watertightness between the small diameter portion 19 and the enlarged diameter portion 15 is fitted on the outer periphery of the small diameter portion 19.

As shown in FIGS. 1, 4 and 5, a face plate 31 is attached to the front surface of the upper end portion of the head body 13, and the face plate 31 is provided with a plurality of sprinkler holes 32. A synthetic resin material is provided on the inner surface of the face plate 31, and a protruding portion 40 formed in the synthetic resin material is located in a small hole of the face plate 31, and a sprinkling hole 32 is formed in the protruding portion 40. .. Then, tap water from the water supply hose 14 passes through the handle 12 and the head main body 13 and is sprinkled as shower water from the sprinkler hole 32. The face plate 31 is rotated around a center thereof within a predetermined angle (for example, 45 degrees) with a rotational resistance, and the sprinkling pressure of shower water is adjusted according to the rotational operation. In this embodiment, the left side in FIG. 5 is the front part of the shower head 11, and the upper side in the figure is the upper part. Further, the left side in FIG. 4 is the left side of the shower head 11.

As shown in FIGS. 2, 5 and 6, boss portions 33 are integrally formed on the outer peripheral portion of the front surface of the face plate 31 at substantially equal angular intervals. A spherical rotating body 35 for massage is rotatably supported on the boss portion 33 via a shaft 34. Although not shown, the rotating body 35 is configured so as not to be detached from the face plate 31 and the rotating body 35 so as not to be detached from the shaft 34. As shown in FIG. 4, the rotating body 35 is located on the outer peripheral portion of the face plate 31, and is located on each vertex (corner) of a substantially square shape. As shown in FIGS. 1 and 4, the sprinkler holes 32 are arranged at positions between the rotating bodies 35 so that the shower water avoids the rotating body 35 and hits the shower user more.

As shown in FIGS. 4 to 6, the shaft 34 of the rotating body 35 is installed on the axis β that directs the radial direction diagonally outward with the center α of the face plate 31 as the center. That is, in the side view shown in FIG. 5, the angle θ1 of the axis β of each pair of upper and lower axes 34 located on the left and right sides of the face plate 31 is inclined with respect to the center line γ orthogonal to the front surface of the face plate 31 at the center α. ing. Further, in the top view and the bottom view shown in FIG. 6, the angle θ2 of the axis β of each pair of left and right axes 34 located above and below the face plate 31 is inclined with respect to the center line γ. In the present embodiment, the tilt angle θ1 in the side view and the tilt angle θ2 in the top view and the bottom view with respect to the center line γ are 27 degrees, respectively. Therefore, the pair of upper and lower rotating bodies 35 are rotated around the shaft 34 arranged at the upper and lower opening angles of 54 degrees, and the pair of left and right rotating bodies 35 are centered on the shaft 34 arranged at the left and right opening angles of 54 degrees. Is rotated to. For the inclination angles θ1 and θ2, values within the range of 15 to 45 degrees are selected. Therefore, a value within the range of 30 to 90 degrees is selected for the opening angle. In this case, the tilt angle θ1 and the tilt angle θ2 may be different.

Next, the operation of the shower head 11 configured as described above will be described.
When the water supply cock (not shown) in the water supply path of tap water is opened, the shower is sprinkled from the sprinkler hole 32, and the shower bath becomes possible.

In this case, if the rotating body 35 is applied to the skin of the body surface portion 50 and the rotating body 35 is pressed against the body surface portion 50 with an appropriate force, the rotating body 35 massages the body surface portion 50 by finger pressure. be able to. Further, by applying the rotating body 35 to the body surface portion 50 and moving the shower head 11 on the skin of the body surface portion 50, the rotating body 35 presses the body surface portion 50 and at the same time massages the body surface portion 50 by rubbing and loosening. be able to. In this case, the moving direction of the shower head 11 is orthogonal to the side of the square in which the rotating body 35 is arranged so that the rotating body 35 is smoothly rotated. That is, in the present embodiment, the inclination angles θ1 and θ2 are formed on the shaft 34 of the rotating body 35. Therefore, when the shower head 11 is moved in one direction, the body surface portion 50 is pressed by the pair of rotating bodies 35 on the front side in the moving direction. Further, as shown in FIG. 7, the body surface portion 50 between the rotating bodies 35 is picked up by the rotating body 35 on the rear side in the moving direction.

As described above, the shower head 11 of the embodiment presses the user's body surface 50 or picks it up and kneads it to provide an effective massage while taking a shower or without taking a shower. It can be carried out.

Therefore, in this embodiment, there are the following effects.
(1) The body surface 50 can be massaged by the rotating body 35 while taking a shower without bringing a dedicated massage tool into the bathroom. Therefore, an effective massage effect can be obtained by promoting blood circulation by the water pressure of the shower water, pressing by the rotating body 35, and picking up. In particular, if massage is performed by the rotating body 35 while taking a hot shower, a high massage effect accompanied by blood circulation promotion can be obtained. Further, since the massage can be performed in the bathtub, a similarly high massage effect can be obtained while soaking in the hot water in the bathtub.

(2) Since the moisturized skin can be massaged by the rotating body 35 while taking a shower or soaking in the hot water in the bathtub, even if the user has dry skin or sensitive skin. , You can do a comfortable massage.

(3) If the rotating body 35 is strongly pressed against the body surface 50, acupressure massage becomes possible. Further, if the rotating body 35 is moved, pressing and picking up can be performed at the same time. The strength and weakness can be determined according to the wishes of the user, and unlike the above-mentioned Patent Document 1, there is no problem that massage becomes impossible by pressing strongly.

(4) Since the axis 34 of the rotating body 35 in the front-rear direction in the moving direction of the shower head 11 is tilted in the opposite direction, the shower head 11 is moved in one direction as described above, so that the shower head 11 is moved. In the front and back of the moving direction, the body surface portion 50 is continuously pressed and massaged so as to be picked up. Further, by moving the shower head 11 in the opposite direction, the body surface portion 50 is similarly continuously pressed and massaged so as to be picked up. Therefore, a high massage effect can be obtained only by moving the shower head 11.

(5) Since the massage is performed by the rotating rotating body 35, unlike the case of massaging by the non-rotating protrusions, the scratching feeling felt by the user on the body surface 50 is almost eliminated, and the feeling of use is excellent. ..

(6) By the pressure of the shower water and the expansion of the pores by the rotating body 35, the dirt to the depth of the pores can be washed away.
(7) If the rotating body 35 is brought into contact with the skin of the body surface portion 50 and a shower bath is taken, the distance between the sprinkler hole 32 and the skin can be kept substantially constant. Therefore, an even shower pressure can be applied to the entire body surface portion 50, and an equivalent massage effect can be given to the whole body.

(8) By massaging the body surface 50 with the rotating body 35 while switching between the hot shower state and the cold shower state, the metabolism of the body surface 50 by promoting blood circulation and the stimulation to the autonomic nerves are promoted. .. Therefore, an effective cosmetological effect and a refreshing feeling can be obtained.

(9) The four rotating bodies 35 are located on the vertices of a quadrangle (almost a square in the embodiment), and the axis 34 of the rotating bodies 35 is extended in an inclined radial direction in which the tip side is widened. It is located on an almost extension of the diagonal line of the quadrangle. Therefore, regardless of whether the shower head 11 is moved up, down, left, or right, simultaneous massage of pressing and picking up can be performed, which is convenient.

(10) Since the rotating body 35 for massage is only supported by the face plate 31 by the shaft 34, the number of parts can be reduced and the configuration can be simplified. Further, since the number of parts is small, the shower head 11 can be easily assembled and the number of failures can be reduced.

(11) Since the sprinkler hole 32 is arranged so as to avoid the position of the rotating body 35, unnecessary discharge of shower water can be suppressed.
(12) Since the head body 13 can be replaced by attaching / detaching the head body 13 of the shower head 11 to / from the handle 12, for example, a head body 13 having a rotating body 35 and a head body having no rotating body 35 If you prepare, you can replace it as needed. In this case, if the head body 13 is turned about 90 degrees with respect to the handle 12, the head body 13 can be attached to and detached from the handle 12. Therefore, unlike the case where the head main body 13 is rotated a plurality of times to be attached and detached, even if the head main body 13 is wet with water or soapy water and is in a slippery state, the attachment and detachment becomes easy. Further, if the head body 13 is removed from the handle 12, the head body 13 can be used as a massage tool even outside the bathroom.

(13) Since the pressure of the shower water is adjusted by rotating the face plate 31, the rotating body 35 is in contact with the body surface portion 50 and is centered on the center α of the face plate 31. By turning the handle 12, the pressure of the shower water can be easily adjusted with one hand.

(Second Embodiment)
Next, the second embodiment of the present invention will be described with reference to FIG.
In the second embodiment, the pair of rotating bodies 35 are provided only on the upper side of the face plate 31, and the lower rotating body 35 is omitted. Further, a plurality of protrusions 36 are formed on the outer peripheral surface of the rotating body 35.

Therefore, in the second embodiment, there are the following effects.
(14) The number of rotating bodies 35 is reduced, and the configuration is further simplified. Further, since the protrusion 36 of the rotating body 35 locally hits the body surface portion 50, a higher massage effect can be obtained.

(Third Embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. 9 and 10.
In the third embodiment, the cassa portion 37 is formed so as to protrude from the upper end portion of the face plate 31. The Cassa portion 37 has a concave portion 38 at the center and convex portions 39 located on both sides of the concave portion 38.

Therefore, it is possible to rub the outer corners of the eyes on the side of the convex portion 39. Further, the concave portion 38 can rub a protruding portion such as a jaw. Therefore, in the third embodiment, there are the following effects.

(15) By rubbing the outer corners of the eyes and the chin with the Cassa portion 37, the circulation of blood and lymph in and around those sites can be improved, and an effective cosmetic effect can be expected.
(Fourth Embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG.

In the fourth embodiment, the upper and lower rotating bodies 35 are tilted so as to face the same direction (upward in FIG. 11). This tilt angle is equal to the tilt angles θ1 and θ2. The left and right rotating bodies 35 are inclined as shown in FIG. 6 of the first embodiment.

Therefore, in the fourth embodiment, there are the following effects.
(16) When the shower head 11 is moved in the vertical direction, the upper and lower rotating bodies 35 simultaneously press or pick up the body surface portion 50, so that only one massage of pressing or picking up can be selected.

(Fifth Embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIG.
