Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water gun used in a facility such as a pool. 2. Description of the Related Art In a conventional water gun, pressurized water is injected from an injection nozzle by operating a lever to open an injection valve, and the lever is returned to an original state to close the injection valve. Accordingly, the configuration is such that the pressurized water is not injected from the injection nozzle. [0003] In the conventional water gun, when a lever is operated to open an injection valve, pressurized water is continuously injected from an injection nozzle. However, simply injecting the pressurized water continuously from the injection nozzle is static and lacks interest, so in order to make the ejection of the pressurized water dynamic, when trying to inject the pressurized water intermittently from the injection nozzle, Since the lever must be operated intermittently to open and close the injection valve,
There was a problem that the operation of the lever was troublesome. [0004] The present invention has been made to solve the above-mentioned disadvantages, and provides a water gun capable of intermittently injecting pressurized water even when an injection valve is kept open. Is what you do. According to the present invention, there is provided a water gun for injecting pressurized water from an injection nozzle by opening an injection valve to provide an enclosure provided with an opening through which pressurized water from the injection nozzle passes. One end portion is a blocking portion, and the other end portion is a weight portion. The blocking portion rotatably supports the central portion and pressurized water flowing from the injection nozzle toward the opening of the enclosure at the blocking portion. By providing an urging member for urging the drainage blades and opening the injection valve, the shut-off portion is pushed by the pressurized water, and the inertia of the weight portion deviates from the path of the pressurized water from the injection nozzle toward the opening. Thereafter, pressurized water flowing from the injection nozzle toward the opening is shut off by the urging force of the urging member and the inertia of the weight portion, and the weight portion and / or the urging member are adjusted.
Thereby, the cutoff time of the pressurized water can be adjusted . According to the present invention, the cut-off portion of the drainage blade is pushed by pressurized water by opening the injection valve.
After deviating from the path of the pressurized water from the injection nozzle toward the opening of the enclosure due to the inertia of the weight portion, the pressurized water flowing from the injection nozzle toward the opening is shut off by the urging force of the urging member and the inertia of the weight portion. Therefore, even if the injection valve is kept open, the injection of the pressurized water is performed intermittently. Adjust the weight and / or biasing member.
The pressurized water cutoff time to the desired time.
Can be adjusted. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an appearance of a water gun according to an embodiment of the present invention, FIG. 2 is a sectional view showing an injection valve portion of the water gun shown in FIG. 1, and FIG. 3 is a sectional view showing a drainage portion of the water gun shown in FIG. 4 (a) and 4 (b) are explanatory views showing the operation of the draining blade. In these figures, A indicates a water supply pipe,
A predetermined pressurized water W is supplied from a pump (not shown) or the like, and functions as a support. B indicates a swivel fitting,
One end is connected to the water supply pipe A. C indicates a water gun,
It is connected to the other end of the swivel fitting B. D indicates a hose, one end of which is connected to a connecting pipe E attached to a water gun C. F indicates a drain pipe, one end of which is connected to the other end of the hose D, for returning drain water from the water gun C to a pool or the like. When the drain pipe is fixed to the water supply pipe A, it functions as a support. The above-mentioned water gun C has an injection valve section 1 and
And a drainer 11. The injection valve section 1 includes a cylindrical barrel casing 2, an injection valve 3 fixedly mounted in the barrel casing 2, and attached to the swivel fitting B by communicating the inflow port 3 i with the barrel. It comprises a grip 4 fixed to the barrel casing 2 and a lever 5 rotatably attached to the barrel casing 2 for opening the injection port 3o of the injection valve 3. Here, the injection valve 3 will be described with reference to FIG. 2. When the lever 5 with which the valve rod 3r is engaged is turned counterclockwise against the urging force of the spring 3s, the valve rod 3r is rotated. By moving the inside of the housing 3h to the right, the valve 3v attached to the valve stem 3r opens the injection port 3o of the housing 3h. Therefore, the pressurized water W flowing from the inflow port 3i flows to the injection port 3o of the housing 3h. When the rotating force for rotating the lever 5 in the counterclockwise direction indicated by the two-dot chain line is released, the valve rod 3r moves leftward in the housing 3h by the urging force of the spring 3s, thereby the valve 3v Closes the injection port 3o,
The pressurized water W stops flowing from the inflow port 3i to the injection port 3o. Reference numeral 3g denotes an O-ring disposed around the valve stem 3r, which keeps the space between the housing 3h and the valve stem 3r watertight. Next, the drainer 11 described above will be described with reference to FIG.
In the description, the drainer 11 is provided with a joint 12 attached to the housing 3h of the injection valve 3 in communication with the injection port 3o, and a through hole 13h attached to the joint 12.
A relay block 13 having one end communicating with the joint 12, an injection nozzle 14 mounted on the relay block 13 so as to communicate with the other end of the through hole 13h, and a drainage blade 15 rotatably mounted on the injection nozzle 14. One end is locked to the spray nozzle 14, the other end is locked to the draining blade 15, and the blocking part 15 c of the draining blade 15 is positioned in front of the injection nozzle 14, that is, from the injection nozzle 14 to the box body 19 described later. And a torsion spring 16 as an urging member for urging the pressurized water W toward the opening 19h. The draining blade 15 has one end serving as a blocking part 15c and the other end serving as a weight 15w, and is rotatably supported at the center. Reference numeral 17 denotes an O-ring, which keeps the space between the joint 12 and the housing 3h or the relay block 13 watertight. Reference numeral 18 denotes an enclosing box for accommodating the draining unit 11, and the box main body 1 having the relay block 13 fixed to the inner surface of the bottom.
9 and a lid 20. And the box body 19
An opening 19h through which the pressurized water W from the injection nozzle 14 passes is provided on one side surface, and a drain port 19o is provided at a position lower than the opening 19h, that is, a drain port 19o is provided at the bottom. Tube E is attached. Reference numeral 21 denotes a cylinder, which is attached to the box main body 19 so as to communicate with the opening 19h. Next, the operation will be described. It is assumed that the pressurized water W is supplied to the water supply pipe A by a pump or the like (not shown). First, when the lever 3 is operated to move the valve 3v and open the injection port 3o, as described above, the pressurized water W is supplied from the inflow port 3i to the injection port 3o. It is injected. However, in front of the injection nozzle 14, FIG.
As shown in (b), since the blocking portion 15c of the draining blade 15 urged by the torsion spring 16 is located, the pressurized water W injected from the injection nozzle 14 is blocked.
It is bounced off at 5c, does not go to the opening 19h, and scatters in the enclosure 18. The pressurized water W scattered into the enclosure 18 in this manner is guided to a predetermined portion, for example, a pool through a drain port 19o via a hose D and a drain pipe F, and is drained. After a lapse of a predetermined time, for example, about 0.5 seconds, the blocking portion 15c is pushed by the pressurized water W against the urging force of the torsion spring 16 and the inertia of the weight portion 15w. 4A, and the inertia of the weight portion 15w causes the blocking portion 15c to come off the path of the pressurized water w from the injection nozzle 14 to the opening 19h as shown in FIG. Therefore, the pressurized water W injected from the injection nozzle 14 is supplied to the opening 19 h and the cylinder 21.
It is injected through the inside. When the urging force of the torsion spring 16 is increased and the urging force of the torsion spring 16 is increased, the water draining blade 15 rotates, for example, as shown in FIG. When the torsion spring 16 rotates, the torsion spring 16 starts to rotate counterclockwise by the urging force. Then, due to the inertia that has started to rotate around the weight portion 15w, as shown in FIG. 4B, the blocking portion 15c is rotated to a position where the pressurized water W from the injection nozzle 14 is blocked, and the blocking portion 15c
, The pressurized water W is no longer injected from the cylinder 21. At this time, when the pressing force of the pressurized water W pressing the blocking portion 15c overcomes the urging force of the torsion spring 16 and the inertia of the weight portion 15w, the rotation of the drainage blade 15 stops and starts to rotate clockwise. . Thereafter, since the same operation is repeated, the pressurized water W is intermittently injected from the cylinder 21. As described above, according to the embodiment of the present invention, the opening 19 from the injection nozzle 14 is formed by the blocking portion 15 c of the drainage blade 15 urged by the torsion spring 16.
h, the pressurized water W is intermittently shut off. Therefore, even if the injection valve 3 is kept open by operating the lever 5, the pressurized water W can be intermittently injected, and the operation can be easily performed. Become. And since the injection nozzle 14 and the draining blade 15 were surrounded by the surrounding box 18, it is possible to prevent the audience from being exposed to the pressurized water W. Further, by adding the draining blade 15, the torsion spring 16 and the surrounding box 18 to the conventional apparatus, the intended purpose can be achieved, so that the configuration for achieving the intended purpose can be reduced in cost. . Further, by adjusting the weight of the weight portion 15w and the urging force of the torsion spring 16, the cutoff time of the pressurized water W can be changed, so that the cutoff time of the pressurized water W can be set to a desired time. The water gun C can be rotated in the vertical direction as shown in FIG. 1 because it is rotatably attached to the water supply pipe A by the swivel joint B. Further, since the drainage in the surrounding box 18 is guided to a predetermined place by the hose D and the drainage pipe F, the area around the water gun C is not flooded, and the operator can be prevented from feeling uncomfortable. In addition, since the enclosure 18 is provided with the lid 20, the drainer 11 can be adjusted and repaired by removing the lid 20. In the above-described embodiment, the case of the enclosure 18 has been described by way of example. However, if it is only necessary to prevent the operator from splashing water, another thing, for example, a parabolic antenna having an opening may be used. The injection valve unit 1 and the draining unit 11 may be shut off. Further, the example in which the urging member is the torsion spring 16 has been described, but another urging member that functions similarly may be used. As described above, according to the present invention, the drainage blade urged by the urging member intermittently blocks pressurized water from the injection nozzle toward the opening of the enclosure. Even if the injection valve is kept open, injection of pressurized water can be performed intermittently, and operation becomes easy. And
Since the enclosure is provided, it is possible to prevent the audience from being exposed to pressurized water, and it is more effective to use the enclosure as an enclosure. Further, by adding a draining blade, a biasing member, and an enclosure to the conventional device, the intended purpose can be achieved, so that the configuration for achieving the intended purpose can be reduced in cost. Further, by adjusting the weight of the weight portion and the urging force of the torsion spring, the cutoff time of the pressurized water can be changed, so that the cutoff time of the pressurized water can be set to a desired time.
