Each of the one or more rectangular holes 412 may be formed in the pattern change member 410 on the opposite side where the supply hole 411 is formed, as shown in FIG. 5. Therefore, when one of the one or more supply holes 411 is connected to the supply passage 310 by the rotation of the pattern changing member 410, the direct hole 412 formed on the opposite side of the pattern changing member 410 correspondingly It may be connected to the straight path 320. Accordingly, the fire water supplied to the supply flow passage 310 may flow into the direct flow passage 320 through the hollow and direct holes 412 of the supply hole 411 and the pattern change member 410. As illustrated in FIGS. 4A to 4C and 5, four rectangular holes 412 may be formed at the lower end of the pattern change member 410.

However, the position and the number of the formation of the direct hole 412 is not limited to the embodiment shown in FIGS. 4A to 4C and 5, one side of which is connected to the hollow of the pattern changing member 410 and the other side thereof according to the rotational position. Any position and number may be used as long as the position and number can be connected to the direct flow path 320.

One side of each of the one or more atomizing holes 413 is connected to the hollow of the pattern changing member 410 as shown in Figures 4a to 4c and 5 and the other side is sprayed flow path 330 according to the rotation position It can be connected with. Each of the one or more atomizing holes 413 may be formed in the pattern change member 410 on the opposite side where the supply hole 411 is formed, as shown in FIG. 5. Accordingly, when one of the one or more supply holes 411 is connected to the supply flow path 310 by the rotation of the pattern change member 410, the fine spray hole 413 formed on the opposite side of the pattern change member 410 correspondingly. May be connected to the atomization passage 330.

When the fire water passes through the fine spray hole 413 having the micro-orifice 413a formed on the outflow side, the body 300 is divided into water streams as many as the number of the micro-orifices 413a or partially atomized. The fine atomization flow path 330 will flow. In addition, since the cross-sectional area of the fine atomization flow path 330 is larger than the fine orifice 413a, the pressure of the fire fighting water that has passed through the fine orifice 413a is reduced. Accordingly, the cohesive force of the water particles constituting the fire water is lowered, so that the fire water can be more easily atomized. Therefore, the fire water is sprayed into the atomizing flow path 330 and the nozzle body 510 of the nozzle body 500, the atomizing nozzle flow path 512 and the atomizing spray path 512a or the atomizing protection flow path 512b to be described later. In the case of spraying through the atomizing spray nozzle 530 or the atomizing protective nozzle 540 after flowing, the water can be easily sprayed into the atomizing spray even at low pressure.

As shown in FIG. 5, the micro-orifice 412a may be formed on the outlet side of the second to fourth straight holes 412 of the second to fifth straight holes 412. In addition, as shown in the illustrated embodiment, the number of microorifices 412a is the same as the number of microorifices 412a of the third and fourth orthogonal holes 412, and the number of microorifices 412a of the two orthogonal holes 412 is the same number. The number of microorifices 412a of the two orthogonal holes 412 may be relatively smaller than that of the microorifices 412a of the three or four rectangular holes 412. Accordingly, the smallest flow rate and therefore the largest pressure of fire fighting water can flow through the direct hole 412 through the second direct hole 412, and the intermediate through the third and fourth direct holes 412. Fire flow water of degree flow rate and thus medium pressure may flow into the direct flow path 320, and through the five direct holes 412, the largest flow rate and thus the smallest pressure of fire water flows into the direct flow path 320. It can flow. However, the number of the orthogonal holes 412 in which the microorifices 412a are formed on the outflow side of the plurality of the orthogonal holes 412 and the microorifices 412a formed on the outflow side of the direct holes 412 is the present embodiment. Not limited to this, if the flow rate or pressure of the fire water can be adjusted by the orifice 412a directly to the direct, can be formed of any one or more of the direct hole 412 or any number of the direct hole 412. have.

In addition, as shown in the embodiment shown in FIG. 5, the fine orifice 413a may be formed at the outlet side of the first to third spraying holes 413. In addition, as shown in the illustrated embodiment, the number of fine orifices 413a is the same as the number of fine orifices 413a of the fine atomizing holes 413 and the fine orifices 413a of the fine atomizing holes 413 of the same number. The number of fine orifices 413a of the second atomizing holes 413 may be relatively smaller than the number of microorifices 413a of the first and third atomizing holes 413. . Accordingly, the smallest flow rate and thus the largest pressure of fire fighting water can flow through the second spraying hole 413 to the spraying flow path 330, and the first and third spraying holes 413 are opened. Through the medium flow rate and thus the medium pressure fire water can flow to the fine spray flow path (330). However, the number of fine orifices 413a formed on the outflow side of the plurality of fine spray holes 413 is not limited to this embodiment, but the flow rate or pressure of the fire fighting water sprayed by the fine orifices 413a into the fine spray If this can be adjusted, any atomization hole 413 or any number of the one or more atomization holes 413 is possible.

In addition, when the pattern change member 410 is rotated so that the third supply hole 411 is connected to the supply flow path 310 as shown in FIG. 6B with the third injection pattern, the third direct hole 412 is straight. It is connected to the flow path 320 and the third atomization hole 413 is connected to the atomization flow path (330). Therefore, the medium flow rate and thus the fire pressure water of medium pressure flows through the direct flow path 320 and the fine spray path 330.

Although not shown, when the pattern change member 410 is rotated such that the fourth supply hole 411 is connected to the supply flow path 310 in the fourth injection pattern, the fourth direct hole 412 is a direct flow path 320. ) Thus, the medium flow rate and thus the moderate pressure of the fire water flows in the direct flow path 320.

In addition, when the pattern change member 410 is rotated such that the supply hole 411 is connected to the supply flow path 310 by the 5th injection pattern, the 5th straight hole 412 is connected to the direct flow path 320. .
