Description

TECHNICAL FIELD The present invention relates to a water gun. More specifically, the present invention relates to a water gun that presses or releases a main body made of a hollow elastic body to operate a valve body provided in a small-diameter bottomed cylindrical portion extending in the hollow elastic body to inject water from an injection hole. .

Problems to be Solved by Conventional Techniques and Inventions A conventional water gun has a mechanism for sucking and ejecting water from a tank by the reciprocating motion of a piston incorporated in a case, so that a large load is required for the reciprocating motion of the piston. However, there are problems in that infants and the like are difficult to handle, and the case and the like are often made of hard plastic, which makes them easily broken.

The present invention solves the above-mentioned conventional problems, is easy to operate for infants, school children, etc., is easy to handle, and is excellent in safety, and the pipe end connected to the injection hole is arranged near the valve body. Accordingly, it is an object of the present invention to provide a relatively inexpensive and convenient water gun that can effectively inject a small amount of water in the system into the system and can continuously inject water.

Means for Solving the Problems The present invention will be described with reference to the drawings.

The water gun 1 of the present invention comprises a hollow elastic body 2 having a toy-shaped main body, and a liquid injection hole 21 is provided at one end of the hollow elastic body 2.
Is provided at the other end, and a bottomed cylindrical portion 3 having a valve hole 31 on the bottom surface and having a diameter smaller than that of the hollow elastic body 2 is extended, and a valve body 4 for closing the valve hole 31 is arranged inside the bottom surface. The pipe 5 is provided between the injection hole 21 and the valve body 4 and is connected to the injection hole 21, and the other end is connected to the injection hole 21. The hollow elastic body 2 is formed so as to project into the bottomed cylindrical portion 3 and is located in the vicinity of the valve body 4.
It is a requirement that the valve body 4 is actuated by pressing or releasing the pressure to close or open the valve hole 31 so that the liquid can be sucked and ejected.

In the above description, the hollow elastic body 2 is formed of soft plastic, rubber or the like, and must have endurance to withstand repeated pressing operations and restoration from the pressed state to the original state. The appearance can be various toy shapes to enhance toy characteristics.

One end of the pipe 5 is connected to the injection hole 21 and is made to be present in the hollow portion of the hollow elastic body 2, and the other end of the pipe 5 is connected to the valve body 4.
Since the liquid is stored in the vicinity, it is possible to effectively jet the liquid even if the amount of the liquid stored in the tip portion of the bottomed tubular portion 3 is small.

When the hollow elastic body 2 presses the valve body 4, the internal pressure rises so that the valve hole 3
It is sufficient that the structure is in close contact with No. 1 and is capable of jetting, and on the other hand, the above-mentioned intimate state is released by releasing the pressing and the liquid can be sucked in, which satisfies the repeated operation. Specifically, it is an integrally molded soft plastic body having a locking projection having a flat plate portion and a brim portion 41 protruding from the central portion of the flat plate portion, and is attached to the locking hole 32 on the bottom surface of the bottomed tubular portion 3. Structure (Fig. 2 ~
(See FIG. 4), the flat plate-shaped soft plastic is arranged on the upper surface of the bottom surface, and the projection 3 is formed by projecting the upper part from the bottomed cylindrical portion 3 side wall.
3, the structure in which a slight upward movement is held (see FIG. 5), and the spherical valve body 4 is also held in a state in which the upward movement is restricted (Sixth Embodiment) (See the figure) and the like.

The process of recovering the liquid from the deformed state to the original state by releasing the pressing of the hollow elastic body 2 with the tip of the bottomed tubular portion 3 (the valve hole 31 portion) being submerged in water Then, a negative pressure is generated in the hollow elastic body 2 to reduce the pressure in the system, and the valve body 4 that closes the valve hole 31 is moved or deformed upward to release the close contact with the valve hole 31 and liquid. Inhale. When the liquid is injected, the pressure in the system is increased by the compression by pressing the hollow elastic body 2, the pressure is applied to the liquid stored in the system, and the valve body 4 is actuated in the opposite manner to that at the time of suction and the valve hole is formed. 31 is closed and liquid is ejected from the ejection hole 21. In the system in which the pipe 5 is connected to the injection hole 21 and the end of the pipe 5 is located near the valve body 4 arranged in the bottomed tubular portion 3,
When the hollow elastic body 2 is pressed, the valve hole 31 is closed by the valve body 4, and the air flows into the pipe 5, and accordingly, the air is ejected from the ejection hole 21 to the outside. And
By the operation of the valve body 4 similar to the above by releasing the pressing of the hollow elastic body 2, the inside of the system is depressurized and the liquid is sucked.
Since the end of the pipe 5 is located in the vicinity of the tip of the bottomed tubular portion 3, even a small amount of liquid stored in the bottomed tubular portion 3 can be effectively ejected.

Example (see FIGS. 1 to 4) The hollow elastic body 2 is made of soft vinyl chloride resin, is a molded body in the shape of a penguin having a hole in the bottom thereof, and has vinyl chloride from the inside to the wings of the penguin. An ABS resin nozzle member to which a resin pipe 5 is connected is mounted to form a main body. The bottomed tubular portion 3 is constructed as follows, and after the valve body 4 is attached to the bottom surface, the end portion is inserted into the bottom hole of the main body to assemble the water gun 1.

The bottom surface of the bottomed tubular portion 3 is formed by injection molding of ABS resin, and a locking hole 32 is provided in the central portion, and four valve holes 31 are arranged around the locking hole 32. The valve body 4 is a soft vinyl chloride material integrally provided with a locking projection having a flat plate portion and a flange portion 41 having a diameter larger than that of the locking hole 32 in the central portion thereof. (The collar portion is inserted in a deformed state), and the collar portion 41 is projected and locked to the bottom surface. The bottomed tubular portion 3 is assembled by contacting and joining semi-cylindrical members. In this process, the plate-shaped bottom surface having the valve element 4 is attached by being sandwiched by the semi-cylindrical member.

Effect of the Invention Since the water gun of the present invention utilizes the elastic restoring force of the hollow elastic body, which is the main body, it can be operated easily with a weak force without fail compared to the conventional water gun of the type that reciprocates the piston, and the appearance Can be shaped into a toy figure or other shape according to the purpose. Also, because the end of the pipe leading to the injection hole is located near the valve body of the small-diameter bottomed cylinder, even a small amount of water in the reservoir can be injected into the system. In the state of being put in, by continuously pressing and releasing the side portion of the hollow elastic body, continuous injection is possible,
It is suitable for infants, school children, etc. as a water gun that can surely perform continuous injection with a simple operation.
