Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different modes and should not be construed as being limited to the description of the embodiments described below.

FIG. 1 shows a schematic configuration of a shower apparatus 1 according to the present invention. The shower apparatus 1 includes a shower head 10 that will be described in detail below, a water supply unit 20 that is connected to a water supply to supply running water to the shower head 10, one is connected to the water supply unit 20, and the other is connected to the shower head 10. The configuration includes a valve 30 and an operation unit 40 that operates on the water supply valve 30 and the like and operates the flow rate and temperature of running water.

Next, an embodiment according to the shower head 10 of the present invention will be described in detail with reference to FIGS. 2 is a perspective view of the shower head 10 according to the present embodiment, FIG. 3 is a front view and a side view of the shower head 10 according to the present embodiment, and FIG. 4 is an AA shown in FIG. It is sectional drawing of the shower head 10 obtained by a line.

First, the overall configuration of the shower head 10 according to the present embodiment will be described with reference to FIG. The shower head 10 includes a base portion 100, a nozzle portion 200, and the like. The base portion 100 is connected to the nozzle portion 200 at one end 100A, and is connected to the shower hose 400 at the other end 100B. Further, as shown in FIG. 4, a water passage 300 is formed inside the base portion 100 and the nozzle portion 200. The shower hose 400 is connected to the water supply valve 30 described above.

As shown in FIGS. 2 and 3, the base 100 is formed such that the diameter on the one end 100 </ b> A side is smaller than the diameter on the other end 100 </ b> B side. Here, the diameter on the one end 100A side is preferably 1 cm to 2 cm. By setting it as such a diameter, the shower head 100 can be inserted in a narrow area | region like an intraoral area, maintaining appropriate durability, and sufficient cleaning function can be ensured.

In the present embodiment, the base portion 100 includes a body portion 120 to which a user's hand is attached, and an elongated extended neck portion 130 that is connected to the body portion 120 and extends along the length direction. Here, it is preferable that the extended neck portion 130 is formed thinner than the trunk portion 120. By providing such an extended neck portion 130, the nozzle portion 200 can be easily arranged even in a narrow region.

Moreover, the extended neck part 130 may be provided so that expansion-contraction is possible along a length direction. Thereby, the position of the nozzle part 200 can be adjusted appropriately according to the cleaning location, and the burden on the user's cleaning work can be reduced.

However, the base 100 is not configured to connect the body 120 and the extended neck 130 which are separate members, but may be a form in which all are integrally formed. At this time, the shape of the base 100 may be such that the diameter gradually increases from the one end 100A side toward the other end 100B side, but is not limited thereto.

The nozzle part 200 is a member for injecting water flowing through the water passage 300 and has a water sprinkling part 220 having a plurality of water sprinkling holes 210. The nozzle part 200 is connected to the one end 100A (or the extended neck part 130) of the base part 100 as described above.

Although the shower head 10 is configured as described above, the diameter of the one end side 100A of the base 100 is extremely thin (that is, the diameter of the water passage 300 at the location is also extremely thin). The flow rate of water sprayed from the portion 200 changes greatly. Therefore, a large pressure is applied to the location where water is injected. Therefore, it is preferable that the base unit 100 includes means for controlling the flow rate of water ejected from the nozzle unit 200 (hereinafter, “flow rate control unit”). As the flow rate control means, for example, forms shown in FIGS. 5 and 6 are conceivable.

FIG. 5 shows details of the flow control means using the valve 140. As shown in FIG. 5 (a), the valve 140 is connected to the valve base 141 installed substantially perpendicular to the water passage 300, the knob 142 for controlling the flow rate, and the knob 142, And a shaft 143 inserted into the valve base 141. By rotating the knob 142, the shaft 143 in the valve base 141 moves along the width direction to adjust the flow rate.

Moreover, as another form of the valve 140, as shown in FIG.5 (b), it connects with the cover part 144 arrange | positioned in the water flow path 300, the knob | pick part 142, both the cover part 144, and the knob | pick part 142. A configuration including the shaft portion 145 is also conceivable.

In this case, in the initial state, the lid 144 is substantially perpendicular to the water passage 300. Therefore, the flow path of the water flow path 300 is blocked. On the other hand, when the knob portion 142 is rotated, the shaft portion 145 and the lid portion 144 to be connected rotate, and the flow path of the water passage 300 that has been blocked by the lid portion 144 is gradually opened. Thereby, the flow rate can be adjusted.

Further, another flow control means will be described with reference to FIG. FIG. 6 is a vertical sectional view of the shower head 10 showing the inside of the base 100. Here, an elastic body having a predetermined elastic coefficient such as rubber or resin is used as the material for the inner wall 150 of the base portion 100 as the other flow rate control means described above. When the flow rate passing through the water passage 300 is increased, the pressure applied from the running water to the inner wall 150 also increases. At this time, the material of the inner wall 150 is an elastic body, so that the width of the water passage 300 can be expanded using the pressure applied to the inner wall 150.

Thereby, the flow path cross-sectional area S in the water flow path 300 increases, and it becomes possible to change the speed of the flowing water ejected from the nozzle part 200 gently. Thereby, when the flow rate of the water flowing through the water passage 300 is changed, it is possible to prevent a situation in which high pressure water is jetted onto the human body or the like. The expansion of the width of the water passage 300 is continued until the pressure applied to the inner wall 150 due to the increase in the flow rate and the urging force from the elastic body are balanced.

The shower head according to the present invention is suitable for cleaning a narrow region such as the above-described oral cavity, and can be localized in the watering range because the overall size is reduced. For this reason, for example, when cleaning dirt caused by food adhering to clothes, it is possible to reduce the work load without impairing the cleaning function.
