Description

  The present invention relates to a shower head.

  In recent years, using a wall functioning as a magnetic body as a bathroom wall and adding a magnet to the shower head, magnetic adsorption between the bathroom wall and the shower head can be used to allow the user to arbitrarily connect the bathroom wall. A technique has been proposed that enables a shower head to be freely fixed at a position (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 57-85069

  The shower head fixed to the mounting surface of the bathroom wall by magnetic adsorption is used in an environment where water droplets adhere to it, and a large water pressure acts during shower water discharge, so the mounting state on the mounting surface tends to be unstable. Tend. As a method for stabilizing the fixed state with respect to the mounting surface, it is conceivable to increase the magnetic attractive force generated between the mounting surface and the shower head. However, if the magnetic attraction force is increased, a large force is required at the time of removal, and the convenience is lowered.

  The present invention has been made in view of such circumstances, and an object thereof is to achieve both the stabilization of the fixed state of the shower head with respect to the mounting surface and the reduction of the force required for the operation of removing the shower head from the mounting surface. There is.

  A shower head that solves the above problem is a shower head that includes a suction portion that magnetically attracts a predetermined mounting surface, and the first suction portion and the second suction portion that are provided at positions separated from each other as the suction portion. A grip portion that is not magnetically attracted to the attachment surface is provided between the first suction portion and the second suction portion, and the attachment surface and the grip portion in a state of being attached to the attachment surface. A space is provided in the middle or the grip portion for gripping the grip portion by turning a finger around.

  According to the above configuration, since the first attracting part and the second attracting part are provided at positions separated from each other and provided with a plurality of attracting parts, it is easy to ensure a high magnetic attracting force. For this reason, the fixing state of the shower head with respect to the attachment surface is stabilized even when attached to a wet attachment surface, or when the water pressure at the time of shower water discharge is acting, and it is possible to suppress positional deviation and detachment.

  When removing the shower head from the mounting surface, hold the grip portion provided between the first suction portion and the second suction portion, and suction from either the first suction portion or the second suction portion in order. By separating the portion from the mounting surface, the shower head can be removed with a relatively small force with respect to the magnetic adsorption force of the first adsorption unit and the second adsorption unit. In particular, since the grip portion has a shape that can be gripped firmly by turning the finger around, the operation of attaching the shower head to the attachment surface and the operation of removing the shower head from the attachment surface are easy to perform.

In the shower head, it is preferable that the magnetic adsorption force of the first adsorption unit and the magnetic adsorption force of the second adsorption unit are different.
According to the said structure, when removing a shower head from an attachment surface, a shower head can be easily removed by performing operation which makes it separate from an attachment surface in an order from an adsorption | suction part with a small magnetic attraction force.

  In the shower head, at least one of an end portion of the first suction portion opposite to the second suction portion and an end portion of the second suction portion opposite to the first suction portion is provided with the mounting surface. It is preferable that a corner portion that creates a gap between the mounting surface and the mounting surface is provided.

  According to the above configuration, when the shower head is removed from the mounting surface, the operation of tilting the shower head can be easily performed by using the corner portion of the end portion of the first suction portion or the second suction portion as a fulcrum. it can.

In the shower head, the grip portion is formed so as to protrude from the attachment surface side in a state of being attached to the attachment surface.
According to the above configuration, the grip portion can be easily grasped even in a groping state in which the position of the shower head attached to the attachment surface cannot be firmly seen, such as when washing off foam attached to the hair during washing. be able to. In addition, it is possible to prevent the fingertip from hitting the mounting surface when gripping the grip portion.

In the shower head, it is preferable that both the first suction portion and the second suction portion are provided in a portion below the center of the shower face in the vertical direction.
A relatively heavy member tends to be disposed around the shower face in the shower head. Therefore, by providing the first suction part and the second suction part in the part below the center of the shower face as in the above configuration, the center of gravity of the shower head can be easily positioned in the vicinity of the grip part. By positioning the center of gravity of the shower head in the vicinity of the grip portion, an operation for attaching the shower head to the attachment surface and an operation for removing the shower head from the attachment surface are facilitated.

  As shown in FIG. 3, both the first suction portion 20 and the second suction portion 30 are provided in a portion below the center line L of the shower face 12 in the vertical direction. As a result, the center of gravity of the shower head 10 is positioned in the vicinity of the grip portion 14.

  Further, as the second magnet 32, a magnet having a smaller magnetic force than the first magnet 22 is employed. Thus, the second attracting unit 30 is adjusted to have a smaller magnetic attracting force than the first attracting unit 20. In addition, as the 1st magnet 22 and the 2nd magnet 32, permanent magnets, such as an alloy magnet, a ferrite magnet, and a rare earth magnet, can be used.

As shown in FIGS. 1-3, the connection part 18 connected with the water supply hose is attached to the lower part of the housing 11. As shown in FIG.

Next, the operation of this embodiment will be described.
As shown in FIG. 4, the shower head 10 is used by being installed in a bathroom or the like having a wall 40 that functions as a magnetic body. Examples of the wall portion 40 that functions as a magnetic body include a wall panel including a steel plate and a wall panel made of enamel.

  The shower head 10 is configured such that the first suction portion 20 and the second suction portion 30 provided on the back side of the housing 11 are brought into contact with the mounting surface 41 at an arbitrary position on the mounting surface 41 of the wall portion 40. It is attached to the attachment surface 41 based on the magnetic adsorption force generated between the adsorption portion 20 and the second adsorption portion 30 and the attachment surface 41. Specifically, the suction surface 20a of the first suction portion 20 and the suction surface 30a of the second suction portion 30 and the mounting surface 41 are fixed to the mounting surface 41 in a state where the surfaces contact each other.

  At this time, the shower head 10 is adsorbed to the mounting surface 41 at the first adsorbing portion 20 and the second adsorbing portion 30 which are two spaced apart from each other in the vertical direction (longitudinal direction of the shower head 10). Therefore, compared with the structure which concentrated and provided the part attracted | attached to the attachment surface 41, the high magnetic attraction force is obtained.

  On the other hand, when removing the shower head 10 from the mounting surface 41, hold the grip 14 and tilt the shower head 10 upward or downward as shown by the arrow A or arrow B to 2 The adsorption | suction part 30 is spaced apart from the attachment surface 41 in order from one side. And the other side of the 1st adsorption | suction part 20 and the 2nd adsorption | suction part 30 is spaced apart from the attachment surface 41 by pulling the shower head 10 of the inclined state to the front side.

There are corners 33 to be generated. Therefore, the shower head 10 can be easily tilted downward (arrow B side in FIG. 4) by using the corner portion 33 as a fulcrum. Note that the corner 33 of the second attracting unit 30 is configured by the second magnet 32.

  Moreover, in the shower head 10 of this embodiment, the 2nd adsorption | suction part 30 is adjusted so that the magnetic attraction force may become smaller than the 1st adsorption | suction part 20. FIG. Therefore, if the shower head 10 is tilted upward (arrow A side in FIG. 4) and the second suction portion 30 having a small magnetic attraction force is first separated from the mounting surface 41, the shower head 10 can be obtained with a smaller force. Can be removed.

It can be carried out.

  In particular, in the above embodiment, as shown in FIG. 3, a portion of the housing 11 located above the first suction portion 20 and a portion located below the second suction portion 30 are bent to the front side. The gap S1 formed between the mounting surface 41 and the mounting surface 41 is configured to be large. By ensuring the large gap S1, the operation of tilting the shower head 10 with the corner portions 23 and 33 as fulcrums can be performed more easily.

(4) The gripping part 14 is formed so as to protrude from the mounting surface 41 side to the front side in a state of being attached to the mounting surface 41.
According to the above configuration, even when the position of the shower head 10 attached to the attachment surface 41 is not clearly visible, as in the case of washing away bubbles or the like attached to the hair at the time of washing the hair, 14 can be held. Further, it is possible to prevent the fingertip from hitting the mounting surface 41 when gripping the grip portion 14.
