Referring to FIGS. 7 and 8 together, in this embodiment, a water gun capable of continuous spraying includes a main body member, a hole opening/closing member, a handle member, and a handle locking member.

The main body member has a water flow path through which the water flows so that the water can be injected to the outside after being introduced into the body member.

In detail, the body member includes a body part 211, a water flow path, a nozzle part, a body-side protrusion 218, a hole opening/closing side insertion hole, a hole opening/closing side assembly, and a flow accelerator 260. include

The body part 211 forms an outer frame of the body member.

The water flow path is formed to have a predetermined length in the vertical direction inside the main body part 211 and has an inlet hole through which the water flows in from the outside, and a predetermined angle with the inlet hole, and the main body part 211 It includes an accommodating hole 215 in which the water to be sprayed to the outside is accommodated, and a connection hole connecting the inflow hole and the accommodating hole 215.

The nozzle part is coupled to the distal end of the accommodating hole 215 and has a plurality of nozzle holes through which the water is sprayed.

The body-side protrusion 218 protrudes toward the nozzle part by a predetermined length from a surface facing the nozzle part among the inner surfaces of the accommodation hole 215, and communicates with the accommodation hole 215 and the connection hole therein. A protrusion-side through hole 219 is formed.

The protrusion-side through-hole 219 is formed through the body-side protrusion 218 along the longitudinal direction.

In this embodiment, a branch hole 227, a spaced branch hole 226, and a flow guide protrusion 225 are formed in the body-side protrusion 218.

The branch hole 227 communicates with the protrusion-side through-hole 219 so that some of the water flowing in the protrusion-side through-hole 219 can be discharged to the outside of the body-side protrusion 218. The inner circumferential surface and the outer circumferential surface of the body-side projection 218 are passed through.

A plurality of branch holes 227 are formed at a predetermined angle along the circumferential direction of the body-side protrusion 218 .

In addition, each of the branch holes 227 gradually increases from the inner surface of the receiving hole 215 facing the nozzle part toward the outer circumferential surface of the body-side protrusion 218 from the protrusion-side through hole 219. It is formed at an angle so as to be farther away.

Then, the water discharged from each of the branch holes 227 gradually spreads toward the nozzle part.

The separation branch hole 226 communicates with the protrusion-side through-hole 219 so that another part of the water flowing in the protrusion-side through-hole 219 can be discharged to the outside of the body-side protrusion 218. While passing through the inner and outer circumferential surfaces of the body-side protrusion 218, it is formed at a portion that is spaced apart from the branch hole 227 and is relatively close to the distal end of the body-side protrusion 218.

The spaced branch holes 226 are formed in parallel with the branch holes 227, and a plurality of them are formed spaced apart from each other at a predetermined angle along the circumferential direction of the body-side protrusion 218.

In this embodiment, the diameter of the branch hole 227 is formed relatively smaller than the diameter of the protrusion-side through hole 219, and the diameter of the spaced branch hole 226 corresponds to the diameter of the branch hole 227. relatively small compared to

The flow guide protrusion 225 protrudes to a predetermined length from a portion of the outer circumferential surface of the body-side protrusion 218 where the separation branch hole 226 is formed, and the water discharged from the separation branch hole 226 is the protrusion It guides the water to flow in the opposite direction to the direction in which the water flows in the side through-hole 219 .

The flow guide protrusion 225 is formed in an annular shape along the outer circumferential surface of the body-side protrusion 218, and is formed in a pointed shape toward the outside, and its inner surface is formed as it moves away from the body-side protrusion 218. It is formed in a curved shape bent in a direction away from the distal end of the body-side protrusion 218 (a direction approaching the hole opening/closing side insertion hole).

Then, the water discharged from the spaced branch hole 226 flows in a direction opposite to the flow direction of the water flowing from the protrusion-side through hole 219 .

The hole opening/closing side insertion hole communicates with the inflow hole and the connection hole, and is recessed to a predetermined depth so that the hole opening/closing member is inserted.

The hole opening/closing side coupling body is coupled to the inside of the hole opening/closing side insertion hole.

The flow acceleration unit 260 pushes the water accommodated in the accommodation hole 215 so that the water accommodated in the accommodation hole 215 can be sprayed at a relatively high speed when sprayed through the nozzle unit, thereby pushing the water accommodated in the accommodation hole 215. to accelerate the flow of the water contained in (215).

In detail, the flow acceleration unit 260 includes a flow acceleration body 261, a water collector 262, a flow acceleration side communication hole 263, and a flow acceleration side elastic body 264.

The flow accelerating body 261 is formed in a shape surrounding the outer circumferential surface of the body-side projection 218 and is movable along the length direction of the body-side projection 218. will be connected to

The water collecting body 262 extends a predetermined length from the distal end of the flow accelerating body 261 toward the distal end of the body-side protrusion 218, and its inner surface is formed to face the flow guide protrusion 225. .

The inner surface of the water collector 262 is concave with a predetermined curvature to collect the water flowing along the inner surface of the flow guide protrusion 225 after being discharged from the spaced branch hole 226. do.

The flow accelerating side communication hole 263 penetrates the inner and outer circumferential surfaces of the flow accelerating body 261, and is formed in plurality along the outer circumferential surface of the flow accelerating body 261 at a predetermined angle.

The flow accelerating side communication hole 263 is formed parallel to the branch hole 227 and the same number as the branch hole 227 .

The flow accelerating elastic body 264 is disposed between the inner surface of the flow accelerating body 261 and the receiving hole 215 facing the nozzle part so that the flow accelerating body 261 is the main body side stone. To provide elastic force to the flow accelerating body 261 so as to move in the longitudinal direction of the body 218, a compression spring or the like may be suggested as an example.

When an external force is transmitted to the hole opening/closing member through the handle member and the hole opening/closing member moves backward in the direction opposite to the direction in which the water flows, the spaced branch hole 226 moves through the protrusion-side through hole 219 It is formed with a relatively small diameter, and as the branch hole 227 is blocked by the flow accelerating body 261, most of the water introduced into the inlet hole is the hole opening/closing side insertion hole, the connection hole, After flowing through the protrusion-side through hole 219, it is accommodated in the receiving hole 215.

Then, after a predetermined amount of water is accommodated in the accommodating hole 215, some of the water flowing in the protrusion-side through hole 219 is discharged through the separation branch hole 226, and then the flow guide protrusion Guided by 225, it is collected on the inner surface of the water collecting body 262 and pushes the flow accelerating body 261 so that the flow accelerating body 261 moves away from the distal end of the main body side protrusion 218. direction, and by the movement of the flow accelerating body 261, the flow accelerating side communication hole 263 and the branch hole 227 communicate with each other, and the water flows inside the protrusion side through hole 219. Another part is discharged through the flow acceleration-side communication hole 263, and accordingly, the water flowing along the projection-side through-hole 219 and the water discharged through the flow acceleration-side communication hole 263 By pushing the water accommodated in the accommodating hole 215 together, the water accommodated in the accommodating hole 215 can be sprayed from the nozzle unit at high speed.

When the external force transmitted to the hole opening/closing member through the handle member is removed, the restoring force accumulated in the flow accelerating elastic body 264 is restored and the flow accelerating body 261 returns to its original position, thereby opening the branch hole 227. is blocked again by the flow accelerating body 261.

Since the body-side protrusion 218 and the flow accelerator 260 are formed as described above, even if no external force is applied to accelerate the flow of the flow passage or the nozzle portion, the receiving hole 215 ) The flow of the water accommodated in is relatively accelerated so that high-speed injection of the water can be achieved.
