[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water nozzle oscillating device for jetting a jet water flow, and more particularly to a water nozzle oscillating device for jetting a jet water flow laterally in a pool facility or a bathhouse.

[0002]

2. Description of the Related Art In recent years, as a part of leisure facilities, there have been provided bathing facilities such as large pools and baths, in which various pools and bathtub facilities are arranged in a part of the bathing facilities. One of the facilities in the facility is to jet a jet of water in a horizontal direction toward a bather's body.

[0003]

In the conventional equipment for jetting a jet water stream in the horizontal direction, the position where the jet water stream hits is fixed because the water nozzle is fixed. For this reason, there was an inconvenience that the bather had to change his or her posture when trying to apply the jet stream to the whole body. The present invention has been made in view of such a point, and an object of the present invention is to provide a water nozzle device that allows a bather to bathe in a jet water flow without changing his / her posture.

[0004]

The tip of the rotating shaft that is linked with a swing drive mechanism that swings and swings to an air actuator such as a reciprocating rotary air motor or air cylinder via a one-way clutch via a one-way clutch, and the speed reduction mechanism is derived from the one-way clutch. And a combination of a rotating disk having an engaging groove for engaging the pin of the pin gear formed on the peripheral surface, or a combination of a worm gear and a wheel gear. A combination of an eccentric pin protruding at an eccentric position in the side plate portion and a long slot formed in the water nozzle in parallel with the water ejection axis in a state where the eccentric pin is engaged, or a cam and a spring. And a combination is characterized by being configured so as to intermittently swinging the swing water nozzle in reciprocating rotation or reciprocation of the air actuator.

[0005]

According to the present invention, a water nozzle for jetting a jet stream is supported on a base so as to be swingable in two dimensions, and a swing drive mechanism for swinging and swinging the water nozzle is reduced by a one-way mechanism. A pin gear, which is linked to a reciprocating air actuator via a clutch and has a reduction mechanism fixed to the tip of a rotating shaft derived from a one-way clutch, and an engaging groove for engaging the pin of the pin gear on the peripheral surface. An eccentric pin composed of a combination of a formed rotating disk or a combination of a worm gear and a wheel gear and having an oscillating drive mechanism protruding at an eccentric position on a side plate portion of the rotating disk, and an eccentric pin When the water nozzle is intermittently swung by the reciprocating operation of the air actuator, the water nozzle is composed of a combination of a long slot formed parallel to the water ejection axis or a combination of a cam and a spring. Since the structure so as to swing, ejection direction from the water nozzle is changed with time, it is possible to blow a jet water flow throughout the body.

An engaging groove (1) formed at a constant pitch on the peripheral surface of the rotating disc (12).
7). The power transmission mechanism (10) is shown in FIG.
As shown in the figure, the input shaft (20) of the one-way clutch (19) is connected to the output shaft (18) of the air motor (3) via the flexible coupling (21), and the output shaft ( The pin gear (16) is fixed to the tip of (22). As shown in FIGS. 4 and 5, the one-way clutch (19) fixes the rotor (23) having an engaging recess on the peripheral surface to the input shaft (20) and engages with the casing (24). The dowel (25) is pivotally supported in a swingable manner, and the engaging claw (25) is elastically urged by a spring (33) in a direction of engaging with the rotor (23), whereby the rotor (23) is moved to the casing ( 24) is configured to be driven in one direction (clockwise in the figure), and is formed by fixing the output shaft (22) to the casing (24).

Reference numeral 26 in FIG. 1 denotes a jet water jet nozzle.
This is a water supply channel to (2), and the operation of a water pump (27) disposed in the water supply channel (26) is controlled by a command from the control device (28). Reference numeral (29) in FIG. 1 denotes a working air supply / discharge system for the air motor (3). The working air supply / discharge system (29) includes a pair of air ports provided in the air pump (30) and the air motor (3). The air motor (3) is rotated by connecting the (31) and (31) via an electromagnetic four-way valve (32) and switching the electromagnetic four-way valve (32) by a command from the control device (28). It is configured as follows.

In the jet water jet device configured as described above, when the bather presses the start switch, the water pump (27) is operated, the jet water is discharged from the jet water jet nozzle (2), and the start of startup is started. The discharge pressure increases after a few seconds.
On the other hand, the air pump (30) also starts operating based on the operation of the start switch, and the electromagnetic four-way valve (32) is set at a predetermined interval (for example, 1 (1.5 seconds) to start switching of valve opening and closing.

When the electromagnetic four-way valve (32) is switched, the air motor (3) repeats forward and reverse rotation. The forward / reverse rotation at a constant interval is intermittently rotated by the action of the one-way clutch (19), and the intermittent rotation causes the swinging drive mechanism (8) to rotate through the pin gear (16) and the rotating disk (12). The jet water jet nozzle (2) is stepped up and down by pitching intermittently by pitch.
Therefore, the jet water discharged from the jet water jet nozzle (2) moves in a certain angle range. In this case, the horizontal position of the jet water jet nozzle (2) is set as the standby position.

At this position, the jet water jet nozzle (2) is stopped, and by operating the start switch again, it is programmed in the control device to continue the original swing from the stop position for the remaining time. . In this case, after the discharge is stopped, the jet water jet nozzle (2) returns to the horizontal position.

In the above embodiment, the speed reduction mechanism (9) is formed by the pin gear (16) and the rotating disk (12) having the engagement groove (17) formed on the peripheral surface. When the jet water jet nozzle (2) in the standby position attempts to oscillate naturally due to the reaction force due to the moment of the water flow or the weight of the nozzle, the oscillating power is applied to the swing drive mechanism (8) and the deceleration mechanism (9). In order to prevent transmission to the power transmission mechanism (5) via this, if this reduction mechanism (9) is configured by a normal gear transmission mechanism, the reverse driving force is smoothly transmitted to the one-way clutch (19), The nozzle body (6) will operate independently of the control command.
