Patent document

Patent document 1: japanese laid-open patent publication No. 2015-27331

However, the push button provided in the conventional showerhead device as disclosed in patent document 1 is configured such that a biasing member such as a spring is incorporated in the button cover and the pushed button is returned to the original position by its elastic force. When assembling the shower head device, first, the temporary water shut-off mechanism unit including the valve body and the push button are integrally assembled in advance, and the body housings divided around the push button are combined with each other, which results in a complicated manufacturing method requiring much effort. Therefore, as a conventional showerhead device, a structure that allows a water temporarily stopping mechanism to be easily assembled to a main body case is desired, and there is room for improvement in this point.

In addition, the push button provided in the conventional shower device as shown in patent document 1 is configured such that a biasing member such as a spring is incorporated in the button cover, and the pushed button is returned to the original position by the elastic force of the biasing member. In this case, the spring to be biased is not stably pushed in, and there is room for improvement in operability.

In addition, there are problems as follows: when the push button is at the push-in position, the push button cover is shaken under the state of not keeping the push button cover; alternatively, when the shower head is set in such a posture that the push button is pressed downward, only the button cover is moved.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a shower head device in which a water temporarily stopping mechanism can be easily assembled to a main body case.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a shower head device capable of improving operability while stabilizing a pushing operation of a push button.

Technical solution for solving technical problem

In order to solve the above problems and achieve the object, the present invention adopts the following aspects.

(1) One aspect of the present invention provides a shower head device including: a main body housing having a water spray part and a handle part connected to the water spray part; a temporary water stop mechanism unit which is integrally provided with a valve body for opening and closing a flow path and is configured to be capable of temporarily stopping a fluid flowing through the flow path; the handle portion of the main body case has a housing portion capable of housing the temporary water shut-off mechanism unit, and a handle opening portion into which the temporary water shut-off mechanism unit is insertable is formed at an end portion on the opposite side of the water spray portion in the longitudinal direction of the handle portion.

According to the showerhead device of the present aspect, the temporary water shut-off mechanism unit can be inserted into the handle portion of the main body case from the handle opening portion, and can be connected so as to communicate with the flow path in the water spray portion in the state of being assembled in advance in the main body case. Therefore, in this aspect, the temporary water shut-off mechanism unit can be easily assembled only by the work of inserting the temporary water shut-off mechanism unit into the handle portion of the main body case, and the assemblability can be improved.

In this aspect, an integrally molded member having a housing portion capable of housing the temporary water shut-off mechanism unit can be used as the handle portion. Therefore, the present embodiment has the following advantages: for example, troublesome assembly work in the case of combining and joining the components divided into two halves is not required.

(2) The shower head device according to the above (1) may be configured as follows: the temporary water shut-off mechanism unit is provided with a locking mechanism that can be locked to a water spray plate unit having a water spray plate housed in the water spray portion.

In this case, when the shower head device is assembled, the connection can be easily made in the body case in which the connection state is difficult to see by engaging the catch mechanism of the temporary water shutoff mechanism unit inserted into the handle portion with the water spray plate unit housed in the water spray part of the body case.

(3) The shower head device according to the above (1) may be configured as follows: a push button for moving the valve body to open and close is fittable to the temporary water shut-off mechanism unit, and the push button is fittable from the outside of a button opening formed in the handle portion.

In this case, the push button can be provided in an assembled manner to the temporary water shutoff mechanism unit. Therefore, by providing an opening in the handle portion at the mounting position of the push button with respect to the temporary water shut-off mechanism unit, after the temporary water shut-off mechanism unit is housed in the handle portion, only the push button can be mounted on the temporary water shut-off mechanism unit through the button opening formed in the handle portion. Therefore, the temporary water shut-off mechanism unit can be easily assembled without dividing the handle portion.

(4) In the showerhead device according to the above (1), the structure may be such that: the main body case holds a sprinkler plate having a sprinkler hole, a water passage communicating with the sprinkler hole is formed inside, the flow passage opened and closed by the valve body is housed in the main body case and is provided so as to be capable of communicating with the water passage, the main body case is provided with a push button that moves the valve body so as to open and close the flow passage or so as to switch the flow passage, and the push button is locked at a push position by a locked portion provided at the main body case and can be held at the push position.

In this case, when the push button is pushed to the push-in position by the pushing operation at the time of water discharge, the push button can be locked to the locked portion on the main body case side. For example, by positioning the valve element from the water stop position to the water discharge position, water can be supplied to the water spray plate and sprayed from the water spray hole. Therefore, the push button can be maintained in the pushed position. Further, even if the water spray hole is in a downward posture, the push button can be prevented from being thrown downward or from shaking, the push operation is stable, and the operability can be improved.

(5) The shower head device according to the above (4), wherein: the main body case is provided with a button holding piece that can move in a button movement direction of the push button, and the button holding piece is provided with an elastic piece portion that is locked to the locked portion.

In this case, when the push button is pushed to the push-in position by the pushing operation during water discharge, the button holding piece provided in the main body case and moving in conjunction with the movement of the valve body also moves to the push-in side in the button moving direction. Thus, the elastic piece portion of the button holding piece is retained by the retained portion, and the button holding piece and the push button are maintained in the pressed position. Thus, even if the sprinkling surface is in a downward posture, the push button can be prevented from being thrown downward or from shaking.

In the shower device of this aspect, when water is stopped, the elastic piece portion of the button holding piece is elastically deformed by moving the button holding piece to the return side in the button moving direction, and the valve body can be set to the water stop position by releasing the engagement with the engaged portion.

(6) The shower head device according to the above (5) may be configured as follows: the valve body is urged in either one of valve moving directions, a first inclined surface inclined with respect to the valve moving direction is formed at a first end portion of the one side of the valve body, a second inclined surface abutting against the first inclined surface is formed at the button holding piece, and the button holding piece is moved in the button moving direction by pressing the second inclined surface against the one side of the valve moving direction with the first inclined surface in a state where the valve body is urged.

In this case, the first inclined surface of the valve body abuts against the second inclined surface of the button holding piece. Therefore, by the operation of pushing the push button, the first inclined surface and the second inclined surface slide in the respective surface directions, and the valve body can be efficiently and easily moved in the valve moving direction different from the button moving direction via the button holding piece moving in the button moving direction.

Effects of the invention

According to the showerhead device of each aspect of the present invention, the water temporarily stopping mechanism can be easily assembled to the main body case.

In addition, according to the shower apparatus of the respective aspects of the present invention, the pushing operation of the push button can be stabilized, and the operability can be improved.

Thereby, the push button 53 is assembled to the main body case 4.

The push button 53 has a cylindrical shape, and is disposed at a position close to the head main body 41 of the grip portion 42. The push button 53 is provided so that a user can perform a pushing operation in a direction (button moving direction C2) intersecting (here, orthogonal) with respect to the valve moving direction C1. By pressing the push button 53, the valve body 52 built in the grip case 51 is moved in the valve moving direction C1 to open and close the valve, and the water discharge position V1 shown in fig. 6 and the water stop position V2 shown in fig. 5 of the valve body 52 can be switched.

Next, the assembly procedure of the shower head device 1 will be specifically described.

First, the sprinkler plate unit 20 is assembled (see fig. 11). As shown in fig. 2, 4 and 11, the sprinkler plate unit 20 is assembled by integrating the sprinkler member 2 and the water passage member 3 with the fixing screws 50 in a state where the decorative plate 22 and the weight ring 21 are fitted. Next, the integrated sprinkler 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 side (see fig. 12). At this time, the elastic locking piece 265 provided on the outer peripheral portion of the upper sprinkler plate 2A is elastically deformed to be locked to the concave portion 41c formed on the inner peripheral edge portion 41b of the head main body 41, whereby the sprinkler plate unit 20 is fitted to the head main body 41.

Next, as shown in fig. 5 and 6, the valve body 52, the valve support cylinder 54, the valve tip pressing portion 56, and the button holding piece 57 are incorporated into the grip case 51 and integrated therewith. Thereby, the integrated temporary water shutoff mechanism unit 5 is assembled. Then, as shown in fig. 2, 4, and 12, the temporary water shutoff mechanism unit 5 is inserted into the handle portion 42 of the main body case 4 from the handle opening portion 4a, and the temporary water shutoff mechanism unit 5 is coupled to the engaged portion 381 of the fluid introduction path 38 of the upper water passage portion 3A shown in fig. 9, which is a state of being assembled in the main body case 4. Specifically, the engaging mechanism S protruding toward the sprinkler plate unit 20 in the temporary water shutoff mechanism unit 5 is engaged with the engaged portion 381 formed on the outer peripheral surface of the fluid introduction path 38 of the upper water passage portion 3A shown in fig. 3 and 4. In this way, the temporary water shut-off mechanism unit 5 is simply assembled by merely inserting it into the handle portion 42 of the main body case 4.

After the assembly of the temporary water shut-off mechanism unit 5 is completed, as shown in fig. 13, the button portion 53A, the press-fitting member 53B, and the button cover 53C of the press button 53 are attached from the outside of the main body case 4. Specifically, the push-in member 53B in which the button portion 53A and the button cover 53C are incorporated is inserted from the outside to the inside of the button opening 43 formed in the grip portion 42, and as shown in fig. 5 to 8, the first locking claw 531 of the push-in member 53B is locked to the second locking claw 571 of the button holding piece 57 by the locking mechanism. In this way, the push button 53 is assembled to the temporary water shut-off mechanism unit 5 and the main body case 4, and the shower head device 1 as shown in fig. 1 is assembled.

In the shower head device 1 configured as described above, when the push button 53 is pushed to the push-in position F1 by the pushing operation during water discharge, as shown in fig. 6, the button holding piece 57 fixed to the push button 53 also moves in the push-in direction in the button moving direction C2. Thereby, the elastic piece portion 572 of the button holding piece 57 moves from the locking release position P2 shown in fig. 10B to the locking position P1 shown in fig. 10A. That is, the elastic deformation of the engagement release position P2 of the elastic piece portion 572 returns to its original shape. Then, 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 shower head device 1 is oriented with the front surface side (the shower surface 24 shown in fig. 4) facing downward, the locking convex portion 572a is placed on the button holding step portion 513a from above. Therefore, the following does not occur: the elastic piece portion 572 of the button holding piece 57 elastically deforms by the own weight of the push button 53 so as to go over the button holding stepped portion 513 a. Therefore, the state where the button holding piece 57 and the push button 53 are held at the push-in position F1 is maintained. As a result, with this configuration, even when the water application surface 24 is in the downward posture, the push button 53 can be prevented from being thrown downward or rattling, the pushing operation is stable, and the operability can be improved.

By pressing the push button 53 to the push position F1 in this way, the valve body 52 can be moved in the valve moving direction C1 in a direction away from the push button 53 side against the biasing force of the coil spring 55. Thus, by positioning the valve body 52 from the water stop position V2 shown in fig. 5 to the water discharge position V1 shown in fig. 6, water can be supplied to the water spray unit 20 and sprayed from the water spray hole 24 a.

When water is stopped in the shower head device 1, the button holding piece 57 is moved in the direction of returning to the initial position in the button moving direction C2 by the pressing force of the valve body 52 by the elastic force of the coil spring 55. At this time, as shown in fig. 10B, the elastic piece portion 572 of the button holding piece 57 is pressed inward in the left-right direction by the lower inner surface 513c of the lower wall 513B of the front end side case 51A and is elastically deformed. Thus, the locking convex portion 572a of the button holding piece 57 goes over the button holding step portion 513a of the support wall 513 to become the locking release position P2, and moves together with the push button 53 to the push release position F2 shown in fig. 5. When the push button 53 is in the push release position F2, the valve body 52 moves toward the push button 53 in the valve moving direction C1 by the biasing force of the coil spring 55, closes the valve at the water stop position V2 shown in fig. 5, stops the supply of water to the sprinkler unit 20, and is in the water stop state.

Next, the operation of the shower head device 1 of the present embodiment will be described.

In the present embodiment, as shown in fig. 11 to 13, the temporary water shutoff mechanism unit 5 can be inserted into the handle portion 42 of the main body case 4 from the handle opening 4a, and connected so as to communicate with the flow passage (annular water passage 3C) of the sprinkler plate unit 20 in the head main body portion 41 previously assembled in the main body case 4. Therefore, in the present embodiment, the assembly can be easily performed only by the operation of inserting the water temporarily stopping mechanism unit 5 into the handle portion 42 of the main body case 4, and the assemblability can be improved.

In the present embodiment, an integrally molded tubular member having a housing portion capable of housing the temporary water shut-off mechanism unit 5 can be used as the handle portion 42. Therefore, in the present embodiment, for example, a troublesome assembly work such as a case of combining and joining the components divided into two halves is not required.

In the present embodiment, when the showerhead device 1 is assembled, the snap mechanism S of the temporary water shut-off mechanism unit 5 inserted into the handle portion 42 is engaged with the fluid introduction passage 38 of the upper water passage portion 3A of the water spray plate unit 20 housed in the head main body portion 41 of the main body case 4. With this configuration, the sprinkler plate unit 20 and the temporary water shut-off mechanism unit 5 can be easily connected in the main body case 4 in which the connected state is hardly visible.

In the present embodiment, the push button 53 can be provided so as to be attached to the temporary water shutoff mechanism unit 5. Therefore, by providing the button opening 43 in the handle portion 42 at the mounting position of the push button with respect to the temporary water shut-off mechanism unit 5, after the temporary water shut-off mechanism unit 5 is housed in the handle portion 42, only the push button 53 can be attached to the temporary water shut-off mechanism unit 5 through the button opening 43 formed in the handle portion 42. Therefore, the assembly can be easily performed without dividing the grip portion 42.

As described above, according to the showerhead device 1 of the present embodiment, the temporary water shut-off mechanism unit 5 can be easily assembled to the main body case 4.

In the present embodiment, the first inclined surface 56a of the valve body 52 abuts against the second inclined surface 57a of the button holding piece 57. Therefore, by sliding on both the

inclined surfaces

56a and 57a by the operation of pressing the push button 53, the valve body 52 can be efficiently and easily moved in the valve moving direction C1 different from the push button moving direction C2 via the push button holding piece 57 moving in the push button moving direction C2.

As described above, according to the showerhead device 1 of the present embodiment, the pushing operation of the push button 53 can be stabilized, and the operability can be improved.

The embodiments of the showerhead device according to the present invention have been described above, but the present invention is not limited to the above embodiments and can be modified as appropriate within a range not departing from the gist thereof.

For example, in the present embodiment, the push button 53 can be provided so as to be fitted from the outside of the button opening 43 formed in the grip portion 42, but the assembly structure of the push button 53 is not limited to this. The showerhead device may be configured to be inserted from the handle opening 4a of the main body case 4 and accommodated in the handle portion 42 even in a state where the push button 53 is previously incorporated in the temporary water shutoff mechanism unit 5.

In the present embodiment, the following configuration is adopted: the push button holding piece 57 is provided to move in the push button moving direction C2 in accordance with the operation of pushing the push button 53 and to move the valve body 52 in the valve moving direction C1, but the present invention is not limited to the configuration in which the push button holding piece 57 is provided, and other mechanisms may be employed. The shower head device may be configured such 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 fixed to the main body case 4 (temporary water shut-off mechanism unit 5) in a push-button operable manner at the time of insertion.

In the present embodiment, the water temporarily stopping mechanism unit 5 and the water passage member 3 are connected by the snap mechanism, but a fixing method other than the snap mechanism may be adopted. The showerhead device may be configured so that the flow paths can be connected to the water passage member 3 in a state in which the flow paths communicate with each other when the temporary water shutoff mechanism unit 5 is inserted into the handle portion 42 of the main body case 4 and stored at a predetermined position.

The configuration of the sprinkler plate unit 20 is not limited to the present embodiment, and may be changed as appropriate. For example, in the present embodiment, the water passage is formed in a doughnut shape, and the water passage member 3 and the water sprinkling member 2 are fixed to each other by the fixing screw 50 at the center portion.

In addition, the weight ring 21 or the decorative plate 22 may be omitted.

In the present embodiment, the engaged portion provided on the main body case 4 side and engaged with the push position F1 of the push button 53 is a button holding step portion 513a formed on the support wall 513 of the grip case 51 (the front end side case 51A), but is not limited to this portion. The shower head device may be provided with the engaged portion on the main body case 4 side, or may be provided in another portion of the grip case 51. In addition, the shower head device may have the following structure: the engaged portion is provided directly on the main body case 4 (the handle portion 42) instead of the grip case 51.

The valve body provided in the temporary water shut-off mechanism unit is a valve body that can move to open and close the flow path in the present embodiment, but may be a valve body that can move to switch the flow path.

Further, the components of the above embodiments may be replaced with well-known components as appropriate without departing from the scope of the present invention.
