Description

Water injection device

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for spraying water, and more particularly, to a water spray apparatus capable of using water for a longer time and increasing a spray range to thereby increase the range of use.

In general, if you want to use water, connect it to the water supply unit or water storage tank through a hose, and connect the nozzle unit to the end of this hose.

In order to clean the indoor floor of the building or to suppress the fire, a nozzle is connected to the hose. The efficiency of water usage depends on the structure of the nozzle connected to the hose.

Especially, the fire-fighting nozzle connected to the end of the fire hose requires direct function because the water spray distance should be secured in the case of suppressing a long distance fire such as a high-rise building. In case of a short-distance fire, There are various requirements such as the ability to radiate fire water.

Also, in the case of a water injection device for cleaning the floor of a building, the efficiency of removing foreign substances attached to the floor depends on the injection pressure, and thus the structure of the water injection device is required to be improved.

However, the water injecting apparatuses proposed so far have not been satisfactorily effective in spraying water to a long distance because the structure in which water is directly applied is a structure that depends on the water pressure.

Korean Patent Publication No. 10-0262197 "Radiant firefighting window" can not increase the injection pressure because water is injected through a single passage.

In addition, there is no disclosure of a means for reducing the use of water so that water can be used for a longer period of time in comparison to the same amount.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the water injection device according to the embodiment of the present invention includes a body cap 2 connected to a water tank or a water supply source through a hose or the like.

The body cap 2 has a cylindrical shape and a thread is formed on the inner side thereof, so that the body cap 2 can be connected to the hose side through a screw connection.

A flow shutoff valve (4) is provided at the other end of the body cap (2) to block or allow the flow of water.

The flow shut-off valve 4 may be a ball valve type commonly used in the field of fluid machinery, a butterfly valve type, or any valve.

The flow shutoff valve 4 is provided with a handle 5 so that the user can manually block or allow the flow of water.

A nozzle body 8 is connected to the other end of the flow shutoff valve 4 through a socket 6.

 The nozzle body 8 is a cylindrical member whose interior is empty, and a nozzle tip portion 10 is provided at an outlet side portion.

As can be understood from FIGS. 2 and 3, the nozzle tip portion 10 is formed with threads on the outer surface thereof, so that the cover member 12 can be coupled to the outside.

The nozzle body 8 has a small diameter portion 14 formed to have a small outer diameter as compared with other portions of the nozzle body 8. The nozzle body 8 and the small diameter portion 14 are integrally formed, .

The small diameter portion (14) forms at least two or more holes (16) communicating with the inner passage.

The nozzle tip portion 10 is formed on the outlet side of the small diameter portion 14, and the nozzle tip portion 10 forms a large diameter portion 17 having an outer diameter larger than that of the small diameter portion.

The large diameter portion 17 has a size such that it is in close contact with the inner surface of the cover member 12 so that a space is formed between the outer surface of the small diameter portion 14 and the inner surface of the cover member 12 do.

Therefore, water flowing into the hole 16 formed in the small-diameter portion 14 flows into this space.

The nozzle tip 10 has an inclined portion 18 connected to the small diameter portion 14 and a plurality of inclined holes 20 are formed in the inclined portion 18.

Six of the inclined holes 20 are formed in the present embodiment, and these inclined holes penetrate the large diameter portion 17.

As shown in FIG. 4, these inclined holes 20 are inclined toward the center C of the nozzle tip portion 10 from the outside, and a main hole 22 is bored in the center C, 8 to pass through.

The holes 20 are not pierced in the circumferential direction at the same position but are pierced at different elevations.

Preferably, the holes 20 form a height in a zigzag form.

In addition, the nozzle tip portion 10 has a groove portion 24 formed inside the inclined portion 18, and an inner inclined portion 26 parallel to the inclined portion 18 is formed around the groove portion 24 have.

A hole 28 is formed in the cover member 12 so that the position of the hole 28 is pierced on the side of the water stream injected from the nozzle tip portion 10. The hole 28 is for sucking air into the cover member 12 when water is sprayed.

5 and 6 show another embodiment of the present invention in which a spinning nozzle 30 is attached to the injection device.

The spinning nozzle 30 includes a cylindrical body 31 having an empty interior and a plurality of spinning holes 32 formed at an outlet side of the spinning nozzle 30.

The body 31 is also provided with a flow shutoff valve 34 which is the same as or similar to the flow shutoff valve 4. The flow shutoff valve (34) is also provided with a handle (35) for operating opening and closing.

The spinning nozzle 30 used in the present invention may have a structure similar to or similar to that of a spinning nozzle generally used, and thus a detailed description thereof will be omitted.

Assuming that the body cap 2 is connected to a water supply source or a hose first, water is injected into the body cap 2 to form a pressure therein State.

In this state, when the user turns the handle 5 to the use position, the water forming the pressure in the body cap enters the nozzle body 8 while passing through the flow shutoff valve 4. [

The water, which is moved to the nozzle body 8 through the nozzle tip 10, is sprayed in a straight-line state. The water stream injected in the direct-acting state generates a rotational force in the water stream as follows.

The water introduced into the nozzle body 8 is discharged through the holes 16 in the nozzle body 8 while the water flowing into the nozzle body 8 is sprayed in a straight- (Not shown).

The cover member 12 is provided on the outer side of the nozzle body 8 so that the water that has flowed out of the nozzle body 8 through the hole 16 flows through the cover member 12 and the nozzle body 8 The water pressure is formed in the space between the outer surface of the small-diameter portion 14 of the first valve body 11 and the second valve body 14.

The water forming the water pressure in the space is injected into the hole 20 formed in the inclined portion 18 of the nozzle tip portion 10 formed on the outlet side of the nozzle body 8,

4, the water injected from the holes 20 is inclined toward the center C because the water is injected into the inclined portion 18 at a predetermined inclination angle, .

When the water injected from the holes 20 is injected in an inclined state, the water collides with the outer surface of the water stream passing through the main hole 22.

Moreover, since the holes 20 have different heights, water streaks are generated at different positions on the outer surface of the water stream injected into the main hole 22. [

That is, since the holes 20 are inclined at an angle of inclination and vary in height, the position at which the water stream injected from the hole 20 collides with the water stream injected from the main hole 22 varies in height .

As a result, a plurality of water streams whose height is varied in the lateral direction of the water stream injected in the water streaming state through the main hole 22 are collided with each other, so that a rotational force is applied to the water stream in the water stream state in the circumferential direction , So that the water stream exiting through the main hole 22 has a rotational force in the circumferential direction and is injected in a straight-ahead state.

The water jetted in the direction of directivity is sprayed along the inner passage of the cover member 12 provided on the outer side of the nozzle body 8. At this time, air is blown through the hole 28 opened in the cover member 12 ≪ / RTI >

The air introduced into the holes 28 is located between the small water streams of the water to be sprayed and is trapped between the water streams during the rotation of the water. If the air is trapped between the water streams, the size of the water stream that is actually sprayed is increased although it is a small form, but the water stream is light because the air is included.

As such, the water injection device according to the present invention can reduce the weight of the water stream while applying rotational force to the water stream in the direction of the circumference in the circumferential direction, so that it can be easily used in the fire fighting of a long distance.

In addition, since the water stream can be made large while making the air layer on the spraying water stream, the water stream rotates, so that the water can be sprayed with a strong water pressure during the fire suppression, so the fire suppression effect becomes better.

In addition, when the water injection device is used for floor cleaning in a building floor, it is possible to separate foreign matters from the floor surface by water as well as spray water during floor cleaning, thereby improving cleaning efficiency.

When the user manipulates the handle 5 to the closing position, the injection of the sprayed water stops.

In the meantime, when the water needs to be sprayed in the radial state as shown in FIGS. 5 and 6, the present invention can spray water in a generally radial state by operating the handle 34 provided in the spinning means to the open position .

Therefore, in the present invention, it is possible to spray in the direct water state or in the waterproof state, and both direct water and waterproof can be sprayed at the same time.
