Embodiments for Carrying Out the Invention

[0010] Hereinafter, an example of a shower head device according to an embodiment of the present invention will be described with reference to the drawings.

[0011] The shower head device 1 of the present embodiment shown in FIGS. 1 and 2 is a hand shower that is connected to a water supply hose 6 (FIG. 1) extended from a water supply source (not shown) and sprays a fluid such as hot water or water from the surface side.

[0012] As shown in FIG. 3, the showerhead device 1 includes a water spraying member 2 having water spraying holes 24a on its surface for spraying fluid, a water passage member 3 having a water passage (annular water passage 3C) communicating with the water spraying holes 24a inside and supplying the fluid from the upstream side to the water spraying member 2, a main body case 4 housing the water spraying member 2 and the water passage member 3, and a primary water stop mechanism unit 5 (see FIG. 2) housed in the main body case 4. In the showerhead device 1, when the water supply to the water spraying member 2 of the fluid is primarily stopped, it is configured such that by operating a push button 53 (described later) provided on the main body case 4, it is possible to switch from water supply to primary water stop.

[0013] The water spraying member 2 and the water passage member 3 are formed in a substantially disk shape by members such as metal and plastic. The water spraying member 2 has an upper water spraying plate 2A and a lower water spraying plate 2B. The water passage member 3 has an upper water passage 3A and a lower water passage 3B. The upper water passage 3A, the lower water passage 3B, the upper water spraying plate 2A, and the lower water spraying plate 2B are arranged in that order from above (the back surface) to below (the front surface). The water spraying member 2 has an accent ring 21 and a decorative plate 22 at the central portion in a plan view seen from the back surface. The upper water spraying plate 2A and the lower water spraying plate 2B are welded in a state of sandwiching the accent ring 21 and the decorative plate 22.

[0014] Here, in the following description, the upper water passage 3A, the lower water passage 3B, the upper water spraying plate 2A, the lower water spraying plate 2B, the accent ring 21, and the decorative plate 22 are arranged on a common axis, and this common axis is referred to as the water spraying axis O. Along the direction of the water spraying axis O, on the surface side where the fluid is discharged, which is the surface side or the lower side, on one surface where the water spraying holes 24a of the lower water spraying plate 2B open, and the other surface side is referred to as the back surface side or the upper side. Also, in a plan view seen from the direction of the water spraying axis O, the direction orthogonal to the water spraying axis O is referred to as the radial direction, and the direction of orbiting around the water spraying axis O is referred to as the circumferential direction.

[0015] As shown in Fig. 3, the lower water-dispensing plate 2B is formed in a circular shape in plan view, has a first opening 23 at the center, and is provided with a water-dispensing surface 24 in which a plurality of water-dispensing holes 24a penetrating in the plate thickness direction are formed. The plurality of water-dispensing holes 24a are evenly arranged along the circumferential direction of the lower water-dispensing plate 2B. The showerhead device 1 discharges fluid in a shower shape from the plurality of water-dispensing holes 24a. The first opening 23 is formed in a substantially rectangular shape with smoothly curved corners. The water-dispensing surface 24 is formed in a convex curved surface that is convex downward from the outer peripheral portion toward the central first opening 23.

[0016] On the back surface of the water-dispensing surface 24, a cylindrical rib 25 that protrudes from the periphery of the first opening 23 toward the back surface side is provided. Inside the cylindrical rib 25, an accent ring 21 and a decorative plate 22 are inserted and accommodated from the back surface side. The accent ring 21 is accommodated inside the first opening 23 of the lower water-dispensing plate 2B and the cylindrical rib 25 from above (the back surface side) with the decorative plate 22 attached.

[0017] The decorative plate 22 has a decorative plate 221 having a flat decorative surface 221a on the lower surface. The decorative plate 221 is formed to be equivalent to the inner peripheral shape of the accent ring 21 and is provided so as to be fitted to the inner peripheral surface of the accent ring 21.

[0018] The decorative plate 22 is mounted on the first opening 23 of the lower water-dispensing plate 2B via the accent ring 21, and the decorative surface 221a is disposed at a position deeper than the surface 24b of the water-dispensing surface 24.

[0019] As shown in Fig. 3, the upper water-dispensing plate 2A has a circular second opening 260 that fits externally onto the cylindrical rib 25 of the lower water-dispensing plate 2B at the center, and is integrally provided by welding over the entire circumference to an outer peripheral wall 2b that protrudes upward inside the radial direction near the outer peripheral edge portion 2a of the lower water-dispensing plate 2B. The upper water-dispensing plate 2A includes a disk portion 261, a screw locking cylinder 263 provided via a connecting piece 262 at the central portion inside the second opening 260 formed at the center of the disk portion 261, and a plurality (here, three) of first flow holes 264 that penetrate the disk portion 261 in the plate thickness direction.

[0020] The disk portion 261 forms an air layer 26A between its upper surface and the downward water passage portion 3B, and an air inlet 26B is formed between its outer peripheral edge and the water passage member 3. The air layer 26A communicates with the space inside the head main body portion 41 of the main body case 4 through the air inlet 26B.

[0021] Also, a water spraying chamber 24A is formed between the upper water spraying plate 2A and the lower water spraying plate 2B. A plurality of first flow holes 264 are provided at predetermined intervals in the circumferential direction, are arranged with a predetermined gap directly below the second flow holes 34 of the downward water passage portion 3B to be described later, and are arranged at coaxial positions. The first flow holes 264 have a throttle shape in which the flow path cross-sectional area is reduced as it goes downward. That is, the first flow holes 264 mix the water sent out from the second flow holes 34 with the air in the air layer 26A of the air intake surface 261a and allow it to pass toward the surface side of the disk portion 261 (the water spraying surface 24 of the lower water spraying plate 2B). In this way, the upper water spraying plate 2A has an ejector function of mixing air into the fluid through the air layer 26A and supplying it to the water spraying chamber inside the lower water spraying plate 2B through the first flow holes 264. Then, the air-containing fluid (water) supplied to the water spraying chamber is sprayed from a large number of water spraying holes 24a.

[0022] The downward water passage portion 3B is arranged at a distance from the back surface side of the disk portion 261 of the upper water spraying plate 2A and is fixed by a fixing screw 50 from above the upper water spraying plate 2A. The downward water passage portion 3B includes a ring-shaped first annular water passage 31, a screw insertion cylinder 33 arranged at the center of the first annular water passage 31 through which the fixing screw can be inserted, and a plurality (here, three) of second flow holes 34 penetrating in the plate thickness direction.

[0023] The upward water passage portion 3A is integrally fixed by welding the outer peripheral edges together on the back surface side of the upward water passage portion 3A, and a donut-shaped annular water passage 3C is formed inside. The upward water passage portion 3A includes a ring-shaped second annular water passage 37 having a fourth opening 36 formed at the center, and a fluid introduction path 38 communicating with the second annular water passage 37 from the side.

[0024] As shown in FIGS. 1 and 2, the main body case 4 includes a head main body portion 41 (water spraying portion) formed with a bowl-shaped portion 41a capable of accommodating a water spraying member 2 and a water passing member 3 on the surface side, a handle portion 42 integrally provided at one end in the longitudinal direction of the head main body portion 41, and a button opening 43 that opens on the surface side of the handle portion 42 and in which a push button 53 to be described later is disposed. Such a main body case 4 is formed of plastic or the like.

[0025] The outer peripheral portion of the lower water spraying plate 2B of the water spraying member 2 is fitted to the inner peripheral edge portion 41b of the head main body portion 41. Thereby, the water spraying member 2 is mounted inside the head main body portion 41. That is, the back surface side and the outer peripheral surface of the water spraying member 2 are covered by the head main body portion 41.

[0026] The handle portion 42 has a cylindrical shape with a flat cross section in which the vertical direction is shorter than the width direction, and has a shape that is easy to grasp and support with one hand. A flow path is formed inside the handle portion 42 along the longitudinal direction of the handle portion 42. The handle portion 42 is provided so as to be able to accommodate a primary water stop mechanism unit 5 inserted from an opening on the base end side opposite to the head main body portion 41 side. The tip of the primary water stop mechanism unit 5 accommodated in the handle portion 42 is connected in a state of communicating with the annular flow path 3C of the upper water passing portion 3A.

[0027] As shown in FIG. 4, the primary water stop mechanism unit 5 is accommodated inside the handle portion 42 of the main body case 4. The primary water stop mechanism unit 5 includes an elongated cylindrical grip case 51 along the shape of the handle portion 42, a valve body 52 that is accommodated in the grip case 51 and opens and closes a flow path that can communicate with the annular flow path 3C of the water passing member 3, and a push button 53 that moves the valve body 52 so as to be able to open and close the flow path.

[0028] As shown in FIGS. 4 to 6, the grip case 51 is longitudinally divided into a distal end side case 51A and a proximal end side case 51B. At the proximal end of the proximal end side case 51B, a male thread 51a for connecting to the water supply hose 6 (see FIG. 1) is formed. As shown in FIG. 4, a handle opening 4a into which the primary water stop mechanism unit 5 can be inserted is formed at the proximal end of the main body case 4 (the end opposite to the water spraying member 2) (see FIGS. 1 and 2).

[0029] As shown in FIGS. 1 and 4, on both sides of the valve body 52 in the distal end side case 51A, a case internal flow path 511 is formed to take in the fluid supplied via the water supply hose 6 into the annular water flow path 3C of the water flow member 3 housed in the main body case 4. The case internal flow path 511 extends along the longitudinal direction of the distal end side case 51A, and the upstream side is connected to a circulation opening 541 (described later) formed in a valve support cylinder 54 described later. This case internal flow path 511 is partitioned by a partition wall from the valve body housing portion 512 side where the valve body 52 is housed.

[0030] As shown in FIGS. 5 and 6, a valve support cylinder 54 that supports the valve body 52 so as to be movable in the valve movement direction C1 at the central portion of the cross section is incorporated in the distal end side case 51A. At the proximal end side of the valve support cylinder 54, a valve seat 54a is provided on which the valve portion 52a of the valve body 52 seats when it moves from the water discharging position V1 where the valve is opened as shown in FIG. 6 to the water stop position V2 where the valve is closed as shown in FIG. 5. A circulation opening 541 connected to the case internal flow path is formed in the valve support cylinder 54. That is, the fluid that has passed through the valve portion 52a flows through the circulation opening 541 and the case internal flow path 511, and is supplied to the annular water flow path 3C of the water flow member 3.

[0031] The valve body 52 is configured to be movable in the valve movement direction C1 of the handle portion 42. A coil spring 55 that biases the valve body 52 toward the water stop position V2 where the valve seat 54a is closed is provided on the valve body 52. One end of the coil spring 55 in the biasing direction is locked to the proximal end portion of the valve body 52, and the other end is locked inside the grip case 51 (proximal end side case 51B), and the valve portion 52a is biased in the direction of seating on the valve seat 54a.

[0032] The valve body 52 is biased toward one end side in the valve movement direction C1 (here, the push button 53 side, the left side in the drawing sheets of FIGS. 5 and 6), and a valve tip pressing portion 56 having a first inclined surface 56a inclined with respect to the valve movement direction C1 is provided at one end.

[0033] As shown in FIGS. 5 to 8, the tip side case 51A is provided with a button holding piece 57 movable in the button movement direction C2 of the push button 53. The button holding piece 57 is provided with a holding main body portion 570 having a second inclined surface 57a that contacts the first inclined surface 56a of the valve tip pressing portion 56. The button holding piece 57, in a state where the valve body 52 is biased, presses the second inclined surface 57a toward one end side (push button 53 side) in the valve movement direction C1 with the first inclined surface 56a, so that the second inclined surface 57a moves along the first inclined surface 56a in the pushing direction of the button movement direction C2.

[0034] The button holding piece 57 is provided with a second locking claw 571 that is locked to a first locking claw 531 of a snap fit mechanism provided on the push button 53.

[0035] Also, as shown in FIG. 9, the tip side case 51A is provided with a pair of support walls 513, 513 for accommodating the button holding piece 57 at the tip side of the valve body 52 (see FIG. 6). The pair of support walls 513 are arranged to face each other with the wall surface direction facing the button movement direction C2 of the push button 53 on both the left and right sides sandwiching the button holding piece 57. Each support wall 513 has an upper wall 513A and a lower wall 513B, and a button holding step portion 513a (locked portion) is formed between the upper wall 513A and the lower wall 513B. The support wall 513 is formed in a stepped shape such that the lower inner surface 513c of the lower wall 513B protrudes inward (button holding piece 57 side) from the upper inner surface 513b of the upper wall 513A. The elastic piece portion 572 of the button holding piece 57 described later can be locked to the button holding step portion 513a.

[0036] Further, on the button holding piece 57, elastic piece portions 572 are provided on both side portions (left and right sides orthogonal to the vertical direction when viewed from the longitudinal direction of the grip case 51), which are engaged with the upper surfaces of button holding step portions 513a formed on a pair of support walls 513, 513 of the tip side case 51A. The elastic piece portions 572 have base end portions 572b connected to the holding main body portion 570 and extending downward. At the free ends of the elastic piece portions 572, locking convex portions 572a protruding toward the support wall 513 side are formed.

[0037] The elastic piece portions 572 are provided so as to be elastically deformable with the base end portions 572b as the bases. As the button holding piece 57 moves in the button moving direction C2, the locking convex portions 572a are configured to take positions between a locking position P1 shown in FIG. 10(a) where they are locked to the button holding step portions 513a of the support walls 513 and a locking release position P2 where the elastic piece portions 572 are elastically deformed and the locking convex portions 572a are disengaged from the button holding step portions 513a and abut against the lower inner surface 513c of the lower wall 513B.

[0038] As shown in FIG. 4, the push button 53 is provided so as to be attachable from the outside to a button opening 43 (see FIG. 4) formed in the handle portion 42 and is locked to the button holding piece 57 by a snap fit mechanism.

[0039] As shown in FIGS. 7 and 8, the push button 53 includes a button portion 53A, a pushing member 53B, and a button cover 53C that covers the periphery of the button portion 53A and the pushing member 53B. The pushing member 53B is provided so as to be movable in the button moving direction C2 within the button opening 43. The pushing member 53B is provided with a plurality of protruding portions 530 extending in the button moving direction C2, and the above-described first locking claws 531 are formed at the protruding tips of these protruding portions 530. As described above, the first locking claws 531 can be locked to the second locking claws 571 of the button holding piece 57. The push button 53 is assembled to the main body case 4 by engaging the first locking claws 531 of the pushing member 53B with the second locking claws 571 of the button holding piece 57 by a snap fit mechanism in which the push button 53 is inserted from the outside to the inside of the button opening 43 formed in the handle portion 42.

[0040] The push button 53 has a cylindrical shape and is disposed at a position near the head main body 41 of the handle portion 42. It is provided such that a user can press it in a direction (button movement direction C2) that intersects (here, is orthogonal to) the valve movement direction C1. By pressing the push button 53, the valve body 52 built into the grip case 51 moves in the valve movement direction C1 to open and close the valve, and an operation can be performed to switch between the water discharge position V1 shown in FIG. 6 of the valve body 52 and the water stop position V2 shown in FIG. 5.

[0041] Next, the assembly procedure of the shower head device 1 will be specifically described. First, as shown in FIGS. 2, 4, and 11, a water diffusing plate unit 20 (see FIG. 11) in which the decorative plate 22 and the accent ring 21 are incorporated and the water diffusing member 2 and the water passage member 3 are integrated using the fixing screw 50 is assembled. Next, the integrated water diffusing plate unit 20 is detachably fitted to the inside (bowl-shaped portion 41a) of the head main body 41 of the main body case 4 from the front surface side (see FIG. 12). At this time, the elastic locking piece 265 provided on the outer peripheral portion of the upper water diffusing plate 2A is elastically deformed and locked to the recess 41c formed in the inner peripheral edge portion 41b of the head main body 41, so that the water diffusing plate unit 20 is fitted to the head main body 41.

[0042] Next, as shown in FIGS. 5 and 6, a primary water stop mechanism unit 5 in which the valve body 52, the valve support cylinder 54, the valve tip pressing portion 56, and the button holding piece 57 are incorporated and integrated in the grip case 51 is assembled. Then, as shown in FIGS. 2, 4, and 12, the primary water stop mechanism unit 5 is inserted into the handle portion 42 of the main body case 4 from the handle opening 4a and connected to the locked portion 381 of the fluid introduction path 38 of the upper water passage portion 3A shown in FIG. 9 that has been previously assembled in the main body case 4. Specifically, the snap fit mechanism S protruding toward the water diffusing plate unit 20 side in the primary water stop mechanism unit 5 is locked to the locked portion 381 formed on the outer peripheral surface of the fluid introduction path 38 of the upper water passage portion 3A shown in FIGS. 3 and 4. In this way, the primary water stop mechanism unit 5 can be easily assembled only by inserting it into the handle portion 42 of the main body case 4.

[0043] After the assembly of the primary water stop mechanism unit 5 is completed, as shown in FIG. 13, the button portion 53A, the pushing member 53B, and the button cover 53C of the push button 53 are attached from the outside of the main body case 4. Specifically, the pushing member 53B incorporating the button portion 53A and the button cover 53C is inserted from the outside to the inside of the button opening 43 formed in the handle portion 42, and the first locking claw 531 of the pushing member 53B is locked to the second locking claw 571 of the button holding piece 57 by a snap fit mechanism as shown in FIGS. 5 to 8. Thereby, the push button 53 is assembled to the primary water stop mechanism unit 5 and the main body case 4, and the assembly of the shower head device 1 as shown in FIG. 1 is completed.

[0044] In the shower head device 1 configured as described above, when discharging water, as shown in FIG. 6, when the push button 53 is pressed to the pushing position F1 by a pressing operation, the button holding piece 57 fixed to the push button 53 also moves to the pushing side in the button moving direction C2. As a result, the elastic piece portion 572 of the button holding piece 57 moves from the unlocking position P2 shown in FIG. 10(b) to the locking position P1 shown in FIG. 10(a). That is, the elastic deformation of the elastic piece portion 572 due to the unlocking position P2 is restored, and the locking convex portion 572a is locked to the button holding step portion 513a of the support wall 513 at the locking position P1. That is, when the surface side of the shower head device 1 (the water scattering surface 24 shown in FIG. 4) is in a downward-facing posture, the locking convex portion 572a is placed on the button holding step portion 513a from above, so that the elastic piece portion 572 of the button holding piece 57 does not elastically deform so as to overcome the button holding step portion 513a due to the weight of the push button 53. Therefore, since the button holding piece 57 and the push button 53 are maintained in the held state at the pushing position F1, it is possible to prevent the push button 53 from protruding downward or rattling even when the water scattering surface 24 is in a downward-facing posture, and the pushing operation is stabilized and the operability can be improved.

[0045] By pressing the push button 53 into the pressed position F1 in this way, the valve body 52 is moved in the valve movement direction C1 against the biasing force of the coil spring 55 in a direction away from the push button 53 side, and the valve body 52 is positioned from the water stop position V2 shown in FIG. 5 to the water discharge position V1 shown in FIG. 6, so that water can be supplied to the water sprinkling plate unit 20 and sprinkled from the water sprinkling holes 24a.

[0046] Also, when stopping the water in the shower head device 1, the button holding piece 57 moves in the button movement direction C2 to the return side by the pressing force of the valve body 52 due to the biasing force of the coil spring 55, and as shown in FIG. 10(b), the elastic piece portion 572 of the button holding piece 57 is pushed inward in the left-right direction by the lower inner surface 513c of the lower wall 513B of the tip-side case 51A and elastically deformed. As a result, the button holding piece 57 reaches the unlocking position P2 where the locking convex portion 572a gets over the button holding step portion 513a of the support wall 513, and moves to the push release position F2 shown in FIG. 5 together with the push button 53. When the push button 53 is at the push release position F2 in this way, the valve body 52 moves in the valve movement direction C1 toward the push button 53 side by the biasing force of the coil spring 55, closes the valve at the water stop position V2 shown in FIG. 5, and the water supply to the water sprinkling plate unit 20 is stopped and the water stop state is achieved.

[0047] Next, the operation of the shower head device 1 according to the present embodiment will be described. In the present embodiment, as shown in FIGS. 11 to 13, the primary water stop mechanism unit 5 is inserted into the handle portion 42 of the main body case 4 from the handle opening 4a, and can be connected in the main body case 4 so as to communicate with the flow path (annular water passage 3C) of the water sprinkling plate unit 20 in the head main body portion 41 that has been assembled in advance. Therefore, in the present embodiment, it can be easily assembled only by the operation of inserting the primary water stop mechanism unit 5 into the handle portion 42 of the main body case 4, and the assemblability can be improved.

[0048] Moreover, in the present embodiment, since a cylindrical member integrally formed with a housing portion capable of housing the primary water stop mechanism unit 5 can be used as the handle portion 42, there is an advantage that laborious assembly such as combining and joining parts that are split in half is not required.

[0049] Further, in the present embodiment, when assembling the shower head device 1, by locking the snap fit mechanism S of the primary water stop mechanism unit 5 inserted into the handle portion 42 to the fluid introduction path 38 of the upper water passage portion 3A in the water dispersion plate unit 20 accommodated in the head main body portion 41 of the main body case 4, the connection can be easily made inside the main body case 4 where the connection state is difficult to visually observe.

[0050] Also, in the present embodiment, since the push button 53 is provided so as to be attachable to the primary water stop mechanism unit 5, by providing the button opening 43 in advance at the mounting position of the push button in the handle portion 42 with respect to the primary water stop mechanism unit 5, after the primary water stop mechanism unit 5 is accommodated in the handle portion 42, only the push button 53 can be attached to the primary water stop mechanism unit 5 from the button opening 43 formed in the handle portion 42. Therefore, it is not necessary to divide the handle portion 42, and the assembly can be easily performed.

[0051] Thus, according to the shower head device 1 of the present embodiment, the primary water stop mechanism unit 5 can be easily assembled to the main body case 4.

[0052] As described above, the embodiment of the shower head device according to the present invention has been described, but the present invention is not limited to the above embodiment and can be appropriately changed without departing from the gist thereof.

[0053] For example, in the present embodiment, the push button 53 is provided so as to be attachable from the outside of the button opening 43 formed in the handle portion 42, but the assembly structure of the push button 53 is not limited to this. In short, even if the push button 53 is pre - incorporated in the primary water stop mechanism unit 5, any configuration that can be inserted and accommodated into the handle portion 42 from the handle opening 4a of the main body case 4 is acceptable.

[0054] In addition, in the present embodiment, a button holding piece 57 is provided that moves in the button movement direction C2 along with the operation of the push button 53 and moves the valve body 52 in the valve movement direction C1. However, the configuration is not limited to providing such a button holding piece 57, and other mechanisms can also be adopted. The key point is that the push button 53 can be inserted from the outside to the inside of the button opening 43 of the main body case 4 and is fixed so as to be operable with respect to the main body case 4 (primary water stop mechanism unit 5) when inserted.

[0055] In addition, in the present embodiment, the primary water stop mechanism unit 5 and the water passage member 3 are configured to be connected by a snap fit mechanism. However, it is also possible to adopt fixing means other than the snap fit mechanism. The key point is that when the primary water stop mechanism unit 5 is inserted into the handle portion 42 of the main body case 4 and housed in a predetermined position, a connection structure that can connect the fluid passages of the two to communicate with each other with respect to the water passage member 3 is sufficient.

[0056] In addition, each configuration of the sprinkler plate unit 20 is not limited to the present embodiment and can be changed as appropriate. For example, in the present embodiment, the water passage is in a donut shape, and the water passage member 3 and the sprinkler member 2 are fixed with a fixing screw 50 at the central portion. However, the present invention is not limited to this. It is also possible to omit the accent ring 21 and the decorative plate 22.

[0057] The shower head device of the present disclosure includes a sprinkling part, a main body case having a handle part connected to the sprinkling part, and a valve body that integrally opens and closes a flow path, and a primary water stop mechanism unit that enables primary stopping of the fluid flowing through the flow path. The handle part of the main body case has a housing part capable of housing the primary water stop mechanism unit, and a handle opening through which the primary water stop mechanism unit can be inserted is formed at an end opposite to the sprinkling part.

[0058] According to the shower head device of the present disclosure, the primary water stop mechanism unit can be inserted from the handle opening into the inside of the handle portion of the main body case and connected so as to communicate with the flow path in the water spraying portion that is previously assembled in the main body case. Therefore, in the present invention, it can be easily assembled only by inserting the primary water stop mechanism unit into the handle portion of the main body case, and the assemblability can be improved. Moreover, in the present invention, since a cylindrical member integrally formed with a housing portion capable of housing the primary water stop mechanism unit can be used as the handle portion, there is an advantage that laborious assembly such as combining and joining divided parts is not required.

[0059] The shower head device of the present disclosure may be characterized in that the primary water stop mechanism unit is provided with a snap fit mechanism that can be locked to a water spraying plate unit having a water spraying plate housed in the water spraying portion.

[0060] In this case, at the time of assembling the shower head device, by locking the snap fit mechanism of the primary water stop mechanism unit inserted into the handle portion to the water spraying plate unit housed in the water spraying portion of the main body case, the connection can be easily made inside the main body case where the connection state is difficult to visually observe.

[0061] The shower head device of the present disclosure may be characterized in that the primary water stop mechanism unit is provided with a push button for opening and closing the valve body in a mountable manner, and the push button is provided so as to be mountable from the outside of a button opening formed in the handle portion.

[0062] In this case, since the push button is provided in the primary water stop mechanism unit so as to be mountable, by providing an opening in advance at the mounting position of the push button in the handle portion with respect to the primary water stop mechanism unit, after housing the primary water stop mechanism unit in the handle portion, only the push button can be attached to the primary water stop mechanism unit from the button opening formed in the handle portion. Therefore, it is not necessary to divide the handle portion, and the assembly can be easily performed.

[0063] In addition, within the scope not departing from the gist of the present invention, it is possible as appropriate to replace the components in the above-described embodiments with well-known components.
