Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water outlet equipped with an operating tool for changing the water outlet state on the outer peripheral portion.

[Conventional technology]

Generally, a water outlet is composed of a base end portion connected to a water outlet pipe and a tip end portion provided with an operating tool, and the base end portion is rotatable and adjustable around an axis along the water outlet direction with respect to the water outlet pipe. , But the distal end is fixed to the proximal end by screwing. Therefore, conventionally, when the direction of the operating tool is to be changed, the tip end and the base end are pivotally adjusted with respect to the water outlet pipe.

[Problems to be solved by the device]

In the above-mentioned water outlet, in order to be able to adjust the rotation with respect to the hot water pipe while maintaining a beautiful appearance, the cross-sectional shape of the connection portion of the water outlet pipe and the connection portion of the water outlet base end should be the same. It is necessary to form a circle having a diameter, and there is a drawback that the cross-sectional shape of the connecting portion of the water outlet pipe or the connecting portion of the water outlet base end portion cannot be polygonal or elliptical.

In other words, if the cross section of the water outlet pipe or the water outlet is changed to a flat elliptical shape, etc., the connection between the water outlet pipe connection and the water outlet base end when the water outlet is rotated is adjusted. There was a shape mismatch between the parts, and the appearance could not be kept beautiful.

The present invention was devised with this situation in mind, and the purpose thereof is to adopt various transverse cross-sectional shapes for the water outlet pipe and the water outlet tool while allowing the orientation of the operating tool to be changed. It is to provide possible flooding equipment.

[Means for Solving the Problems]

In order to achieve the above object, in a water outlet according to the present invention, a distal end portion including an operating tool is attached to a base end portion connected to a water outlet pipe so as to be rotatable and adjustable around an axis along the water outlet direction. The feature is that there is.

[Action]

That is, the direction of the operating portion can be changed by adjusting the rotation of the distal end portion with respect to the base end portion about the axis along the water discharge direction.

[Effect of device]

As a result, it is not necessary to make the connection point between the water pipe and the water outlet base end rotatable so that the cross section shape of the water pipe and the water outlet base end can be maintained while maintaining a beautiful appearance. The cross-sectional shape can now be changed to any shape.

An O-ring (18) that is in close contact with the through hole (14) is externally fitted to the circumferential groove of the vertical axis (16), and the O-ring (18) protruding from the through hole (14) to the mounting portion (13) The middle part of the operating tool (17) is fixed to the lower end. Also,
A downward valve mounting cylinder (20) is integrally formed on the free end side of the valve lever (15), and a spring (2
A spherical valve body (22) is urged downward by 1).

As shown in FIGS. 4 and 5, the partition wall (10) is formed with a shower valve port (23) and a rectification valve port (24) having a smaller diameter than the valve body (22) side by side. Rubber valve seats (25) are attached to these valve openings (23) and (24).

Either one of the left and right sides of the operating tool (17) is projected from the outer periphery of the shower cylinder (7), and when the protruding side of the operating tool (17) is pushed, the valve lever (1
5) swings around the vertical axis (16) in the upper chamber (11), and the valve body (22) is fitted into either the shower valve opening (23) or the rectification valve opening (24), The person who has done so is blocked.

A shower nozzle plate (26) is screwed to the lower end of the shower cylinder (7) so as to sandwich the ring packing (27). The shower nozzle surface (26a) of the shower nozzle plate (26) is formed in a spherical shape with a bulged center,
Further, the area is widened by inclining with respect to the vertical direction, that is, the longitudinal direction of the water outlet, and a large number of small holes (28) are formed on substantially the entire surface.
Is formed along the longitudinal direction of the water discharge tool.

A tubular portion (29) communicating with the rectifying valve port (24) is integrally formed below the valve lever (15).
The upper end opening (31) of the water diversion elbow (30) is fitted and fixed to the lower part of 9). In addition, the lower end opening (3
