1 is a view showing a nozzle assembly 100 according to an embodiment of the present invention.

Referring to FIG. 1 , in the nozzle assembly 100 , a first fluid F1 and a second fluid F2 are each independently introduced, and a first fluid F1 and a second fluid F2 are introduced at the outlet 115 . It can be sprayed more finely while mixing.

The nozzle assembly 100 may be mounted on the external pipe P as shown in the drawing, and may spray the fluid flowing in from the pipe P. However, the present invention is not limited thereto, and the nozzle assembly 100 may be manufactured integrally with the pipe P.

In one embodiment, the first fluid F1 may be a liquid, and the second fluid F2 may be a gas. In the nozzle assembly 100 , the second fluid F2 forms a vortex to more finely atomize the sprayed first fluid F1 .

In the nozzle assembly 100 , the second fluid F2 forms a vortex to more finely atomize the sprayed first fluid F1 . In another embodiment, the first fluid F1 may be a gas, and the second fluid F2 may be a liquid.

The first fluid F1 and the second fluid F2 may be set in various ways depending on the use of the nozzle assembly 100 . For example, if the nozzle assembly 100 is used to finely spray water, the first fluid F1 may be set to water, and the second fluid F2 may be set to air. As another example, if the nozzle assembly 100 is used to supply a drug to a plant such as a plastic house, the first fluid F1 may be set as a drug, and the second fluid F2 may be set as air.

The second pressure of the second fluid F2 flowing into the nozzle assembly 100 may be set to be greater than the first pressure of the first fluid F1 . The high-pressure second fluid F2 may finely split the first fluid F1 so that the first fluid F1 may be finely sprayed. Also, when the second fluid F2 is injected from the nozzle assembly 100 , the first fluid F1 may flow due to a pressure difference. That is, since the outlet 115 of the nozzle assembly 100 is set to a relatively low pressure when the second fluid F2 is injected, the first fluid F1 may move to the outlet 115 due to a pressure difference.

The nozzle assembly 100 may include a base body 110 , an inserter 120 , and a sealing ring 130 . Also, in an alternative embodiment, the nozzle assembly 100 may include a filter 140 .

A first fluid F1 may flow into the first supply line L1 , and a second fluid F2 may flow into the second supply line L2 .

One end of the body 111 may be connected to the pipe P, and the nozzle end 112 may extend to the other end. The inside of the body 111 may have a main space 111A. The body 111 and the pipe P may be assembled in various shapes. In one embodiment, the body 111 and the pipe (P) may be connected by screw coupling.

A supply end 113 is connected to the main space 111A, and the second fluid F2 may be introduced into the supply end 113 . The main space 111A is partitioned by the flange 123, the first fluid F1 flows into the inserter 120 at the rear with respect to the flange 123, and the first fluid F1 flows into the inserter 120 at the rear with respect to the flange 123. The second fluid F2 flows in, and the second fluid F2 may move along the outside of the inserter 120 to the nozzle end 112 and the outlet 115 .

The nozzle end 112 is connected to the body 111 , and the head portion 121 of the inserter 120 may be disposed therein. The inner surface 112A of the nozzle end 112 is in contact with the surface of the head portion 121 . The head 121 may have an outlet 115 disposed at an end thereof. The inner surface 112A of the nozzle end 112 and the surface of the head portion 121 are in close contact, so that the second fluid F2 cannot pass, but the guide groove 120G disposed on the surface of the head portion 121 Accordingly, the second fluid F2 may move.

The supply end 113 may extend to one side of the base body 110 and may be connected to the second supply line L2 . One end of the supply end 113 is connected to the second supply line L2 , and the other end of the supply end 113 is connected to the main space 111A. The second fluid F2 may be supplied into the base body 110 through the supply end 113 .

The protrusion 114 may be disposed at the end of the nozzle end 112 . The protrusion 114 may be disposed outside the outlet 115 . When cleaning the nozzle assembly 100 , the user closes the tip of the nozzle end 112 , and presses the user's finger after placing it on the protrusion 114 . Then, the second opening 110H of the nozzle end 112 is completely blocked, and the second fluid F2 may be introduced into the inserter 120 . This will be described in detail below.

The outlet 115 may be disposed at one end of the base body 110 , and the first fluid F1 and the second fluid F2 may be discharged. The outlet 115 is disposed inside the nozzle end 112 , and may be located at the end of the nozzle end 112 . The outlet 115 has a second opening 110H, and the first fluid F1 and the second fluid F2 may be discharged through the second opening 110H.

In one embodiment, the outlet 115 may have a predetermined internal space. The end of the inserter 120 is connected to the outlet 115, and the first fluid F1 and the second fluid F2 discharged from the inserter 120 pass through the outlet 115 to the nozzle assembly 100. It can be sprayed to the outside of

In an embodiment, the outlet 115 may have a first space 115A and a second space 115B. The first space 115A may be connected to the first opening 120H of the inserter 120 , and the second space 115B may be connected to the second opening 110H of the base body 110 .

The first space 115A may be formed to be larger than the second space 115B. The first space 115A provides a predetermined space to the high-pressure second fluid F2 transformed into a vortex to guide the first fluid F1 to move forward, and to further fine-tune the first fluid F1. It can be crushed finely. Since the second space 115B has a smaller volume than the first space 115A, the injected first fluid F1 may be more strongly injected.

In detail, the first width t1 of the first space 115A in the radial direction may be smaller than the second width t2 of the second space 115B. The first opening 120H of the inserter 120 may have a third width t3 , and the third width t3 may be formed to be smaller than the first width t1 and the second width t2 . . The first fluid F1 discharged from the first opening 120H passes through the first space 115A and the second space 115B, and at this time, the first fluid F1 is further caused by the second fluid F2. can be finely ground.

Since the outlet 115 provides a space for receiving the first fluid F1 and the second fluid F2 , the second fluid F2 is introduced into the inserter 120 when the nozzle assembly 100 is cleaned. can do it When cleaning the nozzle assembly 100, when the user closes the end of the nozzle end 112, the second opening 110H of the nozzle end 112 is completely blocked, 2 The fluid F2 may be introduced into the first opening 120H to be introduced into the inserter 120 .

FIG. 2 is a perspective view illustrating the inserter 120 of FIG. 1 , FIG. 3 is a front view of the inserter 120 of FIG. 2 , and FIG. 4 is a plan view of the inserter 120 of FIG. 2 .

1 to 4 , the inserter 120 is inserted into the base body 110 and may have a guide groove 120G disposed on the surface.

The inserter 120 provides a path through which the first fluid F1 and the second fluid F2 respectively move. The first fluid F1 may flow into the inserter 120 , and the second fluid F2 may move along the outer surface of the inserter 120 . The inserter 120 provides a path through which the first fluid F1 moves, and guides the second fluid F2 to turn, so that a vortex may be formed in the second fluid F2 .

In the inserter 120 , the head part 121 , the shaft 122 , and the flange 123 may be disposed in the direction of the first axis AX1 . In addition, a first internal space 121S is disposed inside the head part 121 , a second internal space 122S is disposed inside the shaft 122 , and a third internal space is disposed inside the flange 123 . 123S is disposed, and the first internal space 121S, the second internal space 122S, and the third internal space 123S may be connected to each other in the direction of the first axis AX1.

The head part 121 is inserted into the nozzle end 112 . The surface of the head part 121 is in close contact with the inner surface 112A of the nozzle end 112 , and a movement path of the second fluid F2 may be set by the guide groove 120G.

A guide groove 120G may be disposed on the surface of the head part 121 . A plurality of guide grooves 120G may be provided, and may be disposed to be spaced apart from each other along the inclined surface of the head part 121 . The plurality of guide grooves 120G may be disposed to be spaced apart from each other at equal intervals from the center of the head part 121 .

In one embodiment, as shown in the drawing, the inserter 120 may have three guide grooves 120G disposed on the surface of the head part 121 .

In another embodiment, although not shown in the drawings, the inserter may have two or four or more guide grooves disposed in the head portion.

As another embodiment, although not shown in the drawings, in the inserter, one guide groove may be disposed on the surface of the head portion, and one guide groove may have a spiral shape along the head portion.

Each of the guide grooves 120G may have extension lines shifted from each other. A plurality of guide grooves 120G are disposed on the inclined surface of the head portion 121, and are disposed to be tilted at a preset inclination θ. The extension line of the guide groove 120G does not face the first axis AX1 and extends in the tangential direction of the end of the head part 121 . Since the second fluid F2 moving each guide groove 120G is discharged in a tangential direction from the end of the head part 121 , the flow of the second fluid F2 may have a swirl or vortex.

In detail, the guide groove 120G extends in the i-direction, and the extension line does not intersect the first axis AX1. In addition, the extension lines of each guide groove 120G are disposed so as not to intersect the first axis AX1. Since the guide groove 120G extends to the outside of the first opening 120H, the first fluid F1 is discharged from the first opening 120H and at the same time collides with the swirl of the second fluid F2.

Since the guide groove 120G is disposed not to be parallel to the first shaft AX1, the second fluid F2 discharged from the guide groove 120G may have a turning force. When the second fluid F2 moves in the i-direction, it has a second flow velocity in the tangential direction of the first opening 120H together with the first flow velocity in the first axis AX1 direction. The second fluid F2 moves forward by the first flow rate, and a turning force is generated in the second fluid F2 by the second flow rate.

In one embodiment, the guide groove 120G may have an inlet end 120G-1 through which the second fluid F2 is introduced, and an outlet end 120G-2 through which the second fluid F2 is discharged. The inlet end 120G-1 is disposed under the head part 121 , and the outlet end 120G-2 is disposed in front of the head part 121 and disposed outside the first opening 120H.

For example, in the guide groove 120G, the cross-sectional area of the inlet end 120G-1 may be greater than the cross-sectional area of the outlet end 120G-2. Since the cross-sectional area of the outlet end 120G-2 is larger than the cross-sectional area of the inlet end 120G-1, the discharge rate of the second fluid F2 may increase more than the inflow rate. The second fluid F2 discharged from the guide groove 120G may be discharged with a strong pressure and may have a strong turning force.

For example, the guide groove 120G may have a reduced cross-sectional area from the inlet end 120G-1 to the outlet end 120G-2. Since the cross-sectional area is linearly reduced from the inlet end 120G-1 to the outlet end 120G-2, the flow rate may increase while the second fluid F2 moves along the guide groove 120G. The second fluid F2 discharged from the guide groove 120G may be discharged with a strong pressure and may have a strong turning force.

The shaft 122 is connected to the head part 121 , and the first fluid F1 may pass therein. Although the drawing shows that the shaft 122 has a substantially cylindrical shape, it is not limited thereto and may have various shapes such as a polygonal column.

The diameter of the shaft 122 is smaller than the diameter of the flange 123 , and is formed smaller than the diameter of the lower end of the head part 121 . A space into which the second fluid F2 can be introduced is formed on the outside of the shaft 122, and the space communicates with the guide groove 120G of the head part 121 so that the second fluid F2 enters the guide groove ( 120G).

The flange 123 is connected to the shaft 122 and may extend in a radial direction. The flange 123 may extend to the inner surface of the body 111 to partition the main space 111A of the body 111 . Since the flange 123 partitions the front and the rear of the main space 111A, it is possible to prevent the first fluid F1 and the second fluid F2 from being mixed in the body 111 .

5 : is a figure which shows the modified example of the inserter 120A.

Referring to FIG. 5 , the inserter 120A includes a head portion 121 , a shaft 122 , and a flange 123 , and the outlet end 120G- of the guide groove 120GA disposed in the head portion 121 . The cross-sectional area of 2A) can be set small.

The guide groove 120GA has an inlet end 120G-1A and an outlet end 120G-2A, but the size of the cross-sectional area at the outlet end 120G-2A is the size of the cross-sectional area at the inlet end 120G-1A. It can be set smaller.

In one embodiment, compared with the cross-sectional area of the first opening 120H, the cross-sectional area of the first opening 120H is greater than the cross-sectional area of one outlet end 120G-2A, and the cross-sectional area of the plurality of outlet ends 120G-2A It may be set smaller than the total.

Since one cross-sectional area A1 or A2 or A3 of the outlet end 120G-2A is formed smaller than the cross-sectional area B1 of the first opening 120H, the second fluid discharged from each outlet end 120G-2A ( F2) can have high pressure. The second fluid F2 discharged from the outlet end 120G-2A may be discharged at a high pressure to form a strong swirl, and the first fluid F1 colliding with the second fluid F2 may be finely sprayed.

Since the sum of the cross-sectional areas A1+A2+A3 of the plurality of outlet ends 120G-2A is formed to be larger than the cross-sectional area B1 of the first opening 120H, the second outlet end 120G-2A has a sufficient flow rate. The fluid F2 may be discharged. Since the second fluid F2 discharged from the outlet end 120G-2A is discharged at a sufficient flow rate, the first fluid F1 may be finely sprayed.

6 is a diagram showing another modified example of the inserter.

Referring to FIG. 6 , the inserter 120B may have a spiral guide groove 120GB. The guide groove 120GB is provided in plurality, and may be disposed on the surface of the head part 121 . The guide groove 120GB may have a spiral shape along the surface of the head part 121 .

The guide groove 120GB has an inlet end 120G-1B and an outlet end 120G-2B, and the guide groove 120GB from the inlet end 120G-1B to the outlet end 120G-2B has a spiral. Therefore, the second fluid F2 moving along the guide groove 120GB may have a strong turning force. The second fluid F2 discharged from the outlet end 120G-2B has a strong turning force, the second fluid F2 strongly crushes the first fluid F1, and the first fluid F1 is finely sprayed. can be

Referring back to FIG. 1 , the sealing ring 130 may be disposed inside the base body 110 , at the rear end of the inserter 120 . The sealing ring 130 may seal a gap between the inserter 120 and the base body 110 .

The filter 140 may be disposed between the inserter 120 and the pipe P to filter foreign substances remaining in the first fluid F1 . The filter 140 may remove foreign substances included in the first fluid F1 before the first fluid F1 flows into the inserter 120 .

Since the cross-sectional area of the first opening 120H of the inserter 120 is very small, it may be blocked by the foreign material of the first fluid F1. The filter 140 removes foreign substances remaining in the first fluid F1 so that the first fluid F1 can be sprayed without clogging.

7 is a view showing another modified example of the inserter.

Referring to FIG. 7 , the inserter 120C may include a straight guide groove 120GC. At least one guide groove 120GC may be provided, and may be disposed on the surface of the head unit 121 .

The guide groove 120GC may extend in the direction of the first axis AX1 of the inserter 120C. The guide groove 120GC has an inlet end 120G-1C and an outlet end 120G-2C, and may extend in the direction of the first opening 120H. Since the second fluid ( ) moving along the guide groove ( 120GC ) is discharged to the first opening ( 120H ) of the inserter ( ), the second fluid ( F2 ) may be concentrated in the direction of the first axis ( AX1 ).

In an embodiment, the guide groove 120GC may have a cross-sectional area of the outlet end 120G-2C smaller than a cross-sectional area of the inlet end 120G-1C.

In one embodiment, compared with the cross-sectional area of the first opening 120H, the cross-sectional area of the first opening 120H is greater than the cross-sectional area of one outlet end 120G-2C, and the cross-sectional area of the plurality of outlet ends 120G-2C It may be set smaller than the total.

Since the sum of the cross-sectional areas of the plurality of outlet ends 120G-2C is greater than the cross-sectional area of the first opening 120H, a sufficient flow rate of the second fluid F2 may be discharged to the outlet ends 120G-2C. Since the second fluid F2 discharged from the outlet end 120G-2C is discharged at a sufficient flow rate, the first fluid F1 may be finely sprayed.

FIG. 8 is a diagram illustrating an operation of spraying a fluid from the nozzle assembly 100 of FIG. 1 .

Referring to FIG. 8 , in the nozzle assembly 100 , the second fluid F2 having a turning force may split the first fluid F1 into small pieces, and the first fluid F1 may be finely sprayed.

The first fluid F1 moving along the first supply line L1 passes through the pipe P and flows into the nozzle assembly 100 . The first fluid F1 from which foreign substances are removed by the filter 140 moves in the first axis AX1 direction, passes through the internal space of the inserter 120 , and exits 115 of the base body 110 . move to

The second fluid F2 moving along the second supply line L2 flows into the nozzle assembly 100 through the supply end 113 . The second fluid F2 introduced into the main space 111A of the base body 110 moves along the guide groove 120G and moves to the outlet 115 of the base body 110 . At the outlet of the base body 110 , the first fluid F1 and the second fluid F2 are mixed.

The second fluid F2 moving along the guide groove 120G may have a turning force. The guide grooves 120G are arranged so that the extension lines are shifted from each other, and the guide grooves 120G inject the second fluid F2 from the end of the head part 121 in a tangential direction. The second fluid F2 injected in the tangential direction of the head part 121 acquires a turning force, and the flow of the second fluid F2 is transformed into a vortex.

The first fluid F1 may be finely sprayed by the turning force of the second fluid F2 . When the first fluid F1 and the second fluid F2 are collected at the outlet 115 , the turning force of the second fluid F2 finely pulverizes the first fluid F1 . The strong turning force of the second fluid F2 may break the first fluid F1 into small pieces, and the first fluid F1 may be sprayed very finely.

At the same time, when the first fluid F1 and the second fluid F2 pass through the outlet 115 , the turning force of the second fluid F2 expands the injection area, and the first fluid F1 is injected over a large area. can be Since the second fluid F2 has a turning force extending in the radial direction, the first fluid F1 passing through the second opening 110H can form a large spray area along the flow of the second fluid F2. have.

The first fluid F1 may be finely atomized by the relatively high pressure of the second fluid F2 . The first pressure of the first fluid F1 supplied to the nozzle assembly 100 may be set to be smaller than the second pressure of the second fluid F2 . Since the second pressure is greater than the first pressure, the second fluid F2 may finely atomize the first fluid F1 .

Since the second pressure of the second fluid F2 is greater than the first pressure of the first fluid F1 , when the second fluid F2 is injected, the first fluid F1 is automatically removed from the nozzle assembly 100 . can be sprayed. When the high pressure second fluid F2 is injected, the first fluid F1 may flow into the nozzle assembly 100 due to the pressure difference to perform a function of priming water. That is, even before the pump is driven, the inside of the pump may be filled while the first fluid F1 moves. Thereafter, when the pump is driven in a state in which the first fluid F1 is filled in the inside of the pump, the pump may operate normally.

9 is a diagram illustrating a cleaning operation of the nozzle assembly 100 of FIG. 1 .

Referring to FIG. 9 , when the nozzle assembly 100 closes the outlet, the second fluid F2 may clean the nozzle assembly 100 .

Since the path through which the first fluid F1 or the second fluid F2 moves has a very small cross-section, the nozzle assembly 100 may be easily blocked by foreign substances. The nozzle assembly 100 according to the present invention can clean the inside of the nozzle assembly 100 simply and quickly.

The user may change the movement path of the second fluid F2 by blocking the outlet 115 of the nozzle assembly 100 . The user blocks the sealing member BL at the end of the nozzle assembly 100 so that the first fluid F1 and the second fluid F2 are not discharged to the outside, and move back to the inner space of the inserter 120 . can

The sealing member BL may be set as various components capable of closing the outlet end of the nozzle assembly 100 .

For example, the sealing member BL may be set as a component that blocks the exit end of the nozzle assembly 100 . The sealing member BL may be formed of a material having a surface in contact with the protrusion 114 having a predetermined cushion, and when the sealing member BL applies the protrusion 114, the exit end of the nozzle assembly 100 is closed. can be completely closed.

As another example, the sealing member BL may be set by a user's finger. When the user strongly presses the projection 114 with his finger, the user's finger having a predetermined cushion may completely seal the exit end of the nozzle assembly 100 .

The protrusion 114 may inform the user of a region for closing the outlet end of the nozzle assembly 100 . A user may recognize a portion to be closed of the nozzle assembly 100 through the touch of the protrusion 114 . Also, the protrusion 114 may be strongly in close contact with the sealing member BL having a cushion to completely seal the nozzle assembly 100 .

The inner space of the outlet 115 may provide a space in which the directions of the first fluid F1 and the second fluid F2 are switched. The first fluid F1 and the second fluid F2 colliding with the sealing member BL change their moving directions and move in the reverse direction. In the first space 115A and the second space 115B of the outlet 115 , the moving directions of the first fluid F1 and the second fluid F2 are reversed. In particular, the high-pressure second fluid F2 may be sufficiently diverted in the inner space of the outlet 115 to move in the reverse direction.

While moving in the reverse direction, foreign substances adhering to the first opening 120H or the guide groove 120G may be removed. Since the opening area of the first opening 120H is large, the first fluid F1 and the second fluid F2 flow into the first opening 120H. The first fluid F1 and the second fluid F2 pass through the filter 140 while moving along the inside of the inserter 120 . At this time, foreign substances adhering to the filter 140 can be removed by moving it to the pipe P.

Even during cleaning, the second fluid F2 moves while having a turning force, so that the cleaning effect is increased. In detail, since the second fluid F2 whose direction is changed in the sealing member BL still has a turning force, the second fluid F2 moves the inside of the inserter 120 to finely chop the first fluid F1 . will break Accordingly, the first fluid F1 and the second fluid F2 may effectively clean the nozzle assembly 100 while moving the inner space of the inserter 120 .

The second fluid F2 may clean the nozzle assembly 100 with a strong pressure. In particular, since the second fluid F2 introduced into the inserter 120 has a higher pressure than the first fluid F1 , when the second fluid F2 flows into the inserter 120 , the second fluid F2 The direction of the first fluid F1 is changed along with the fluid F2. When the direction of the high pressure second fluid F2 is changed, the direction of the first fluid F1 is also changed, and the inner space of the nozzle assembly 100 can be effectively cleaned.

When the second fluid F2 is discharged to the nozzle assembly 100 , the first fluid F1 is automatically sucked into the pump 20 . When the high-pressure second fluid F2 is discharged to the nozzle assembly 100 , the first fluid F1 moves to the first filter 41 and the pump 20 due to the pressure difference. That is, the first fluid F1 may flow into the pump 20 to perform the function of a priming water.

When the pump 20 is filled with the first fluid F1 , the pump 20 starts driving. The pump 20 pressurizes the first fluid F1 to a preset pressure, and the pressurized first fluid F1 flows into the nozzle assembly 100 through the second filter 42 .

By adjusting the opening degree of the first valve 51 , the degree of the first fluid F1 injected from the nozzle assembly 100 may be adjusted. In addition, the first fluid F1 recovered through the first valve 51 may recover foreign substances remaining in the second filter 42 to the storage tank 10 .

The first fluid F1 and the second fluid F2 respectively introduced into the nozzle assembly 100 are discharged through the outlet 115 . Since the second fluid F2 has a turning force, the first fluid F1 may be finely pulverized, and the first fluid F1 may be finely sprayed.

<Cleaning Mode>

In the cleaning mode, the injection system 1 may be washed while the first fluid F1 is recovered by changing the movement path of the second fluid F2 .

As the first fluid F1 moves from the storage tank 10 to the nozzle assembly 100 , foreign substances included in the first fluid F1 remain in the filters of the first filter 41 and the second filter 42 . . During cleaning, the second fluid F2 moves in the reverse direction of the first fluid F1 and simultaneously moves the first fluid F1 in the reverse direction. Accordingly, foreign substances remaining in the first filter 41 and/or the second filter 42 may be removed.

The second fluid F2 may recover all of the first fluid F1 remaining in the first supply line L1 . Even after the spraying mode ends, a portion of the first fluid F1 remains in the first supply line L1. During cleaning, the second fluid F2 guides the movement of the first fluid F1 so that the first fluid F1 is returned to the storage tank 10 , and thus the first fluid F1 is connected to the first supply line L1. ) can all be empty. Since the first fluid F1 does not remain in the first supply line L1, it is possible to prevent freezing by the first fluid F1 and to prevent corrosion of the pump 20 by the first fluid F1. can
