Description

Apparatus for spraying fluid

The present invention relates to a fluid injection device for injecting a fluid, such as water, at various distances and ranges.

Conventionally, in order to suppress dust generated in an outdoor yard, a spraying operation was performed through a spraying device using a spraying gun. Conventional sprinkler can be sprayed in the form of a coarse water, such as a general fire hydrant, or by sprinkling by a spring cooler, localized concentration of the water to be sprayed, the watering efficiency is lowered and thus the sprinkled surroundings can be dirty. there was. That is, the conventional watering device using the watering gun is sprayed by blowing a thick stream of water, so that the water consumption is not only high, but it is not suitable for use in a wide area. In addition, there is a disadvantage that the user has to manually adjust the area to be watered.

In order to solve this problem, a spray sprinkler for spraying water particles in a portable spray form is used. The device is equipped with a large amount of nozzles and sprays a large amount of water particles using the wind power of a fan driven by a motor, and can be used for suppressing a wide range of scattering dust in an outdoor yard. Due to this, in the indoor workplace where dust is generated locally, the influence on the surrounding facilities becomes a problem.

In the case of such a conventional spray sprinkler, since the particles sprayed through a large amount of nozzles are always dispersed while maintaining a constant shape, the sprayed width is not variable. That is, it is difficult to cope with the conventional spray water spraying device in the case where intensive spraying is required in a specific area depending on the circumstances of the use site, and in the case where spraying widely spreads over a large area is required. In addition, the conventional spray sprinkler is difficult to variably control the distance sprayed because the wind and wind pressure of the fan driven by the motor is fixed, the user can adjust the direction in which the water particles are sprayed through the manual operation by the handle drive method It was difficult to control the direction of movement.

In addition, in the conventional spray water spraying apparatus, when the water line supplied to the apparatus is turned off after use of the apparatus, a scale that is a determination of adhesion to the pipe and the nozzle may be formed due to the water remaining in the nozzle unit and the recycled water line. there was. The scale is concentrated at the nozzle of the nozzle when the device is used. Among the scales, the smaller scale than the jet is discharged from the jet along with the water, but the scale larger than the jet is accumulated at the jet of the nozzle due to the water pressure to block part of the jet. This occurred. That is, there was a problem that the nozzle's injection hole could not play its role due to the scale being blocked by repeated use of the device, and to prevent this, periodic nozzle replacement or separate nozzle cleaning was required.

The present invention was created to solve the problems described above, the problem to be solved by the present invention can adjust the spraying distance, the spraying direction and the spraying angle in accordance with the user's judgment to immediately utilize or cope with the situation of the workplace To provide a possible fluid jet.

In addition, another problem to be solved by the present invention is to clean the nozzle and pipe after use of the device to prevent the nozzle hole is blocked due to scale and external influences to prevent the performance of the device is degraded and the life of the nozzle can be extended To provide a device.

In addition, another problem to be solved by the present invention is to provide a fluid spray that can be more efficiently driven by the spraying of the fluid particles to almost all the parts where the wind pressure is applied.

In addition, another problem to be solved by the present invention is to provide a fluid injection device that can be made smoothly without manual operation of the overall direction control of the device.

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

1 is a schematic perspective view of a fluid ejection apparatus according to an embodiment of the present invention, Figure 2 is a schematic exploded perspective view of the fluid ejection apparatus of FIG.

1 and 2, a fluid spray apparatus 100 according to an embodiment of the present invention includes a casing 1, a sliding casing 2, a pipe 3, and a plurality of nozzles 4. .

For reference, the fluid generally refers to water, but is not limited thereto, and liquids or gases in various states in accordance with the definition of a fluid having easy-to-deformation, flowing properties, and undetermined shapes may be used. This may be the case. For example, a fluid may mean water additionally containing a specific component.

In addition, the fluid injection device 100 may further include a fluid line 51, an air line 52, a mixer 53, a left and right rotation mechanism 6, and a vertical rotation mechanism 7. However, the configuration of the fluid line 51, the air line 52, the mixer 53, the left and right rotation mechanism 6, and the up and down rotation mechanism 7 is necessarily included in the fluid injection device 100 at the same time. It may not be selected and may be further included as needed.

First, the structure of the casing 1 and the sliding casing 2 is examined.

3 is a schematic side view showing a driving example of a sliding casing.

The casing 1 is equipped with a fan 12 that applies wind pressure forward. In addition, the casing 1 may be equipped with a motor 13 to drive the fan 12. For example, referring to FIG. 2, the fan 12 and the motor 13 may be mounted in the casing 1, that is, in the wind pressure hole 11 to be described later. The wind formed through the fan 12 may move forward through the wind pressure hole 11 of the casing 1 to secure straightness to act as wind pressure for the front.

However, the wind straightness may vary depending on the length of the casing (1). If the length of the casing 1 is long, the wind is straightened in the direction toward the front can be strong straightness. On the contrary, if the length of the casing 1 is short, the wind spreads out of the casing 1 before the wind is completely trimmed in the direction toward the front, and thus the wind spreadability may be increased. This will be described again with respect to the operation of the fluid injection device 100 while looking at the configuration of the sliding casing (2).

1 and 2, the casing 1 and the sliding casing 2 to be described later may include wind pressure holes 11 and 21 formed in the front and rear directions, respectively. For example, although the wind pressure hole 11 of the casing 1 may be generally formed to be completely through in the front and rear directions, a part or the whole of the rear surface of the casing 1 may be blocked or a structure may be provided in the middle. May be In addition, the wind pressure hole 21 of the sliding casing 2 is also not completely through the structure, the structure may be provided as necessary, such as the front end, the middle, the rear end.

At this time, the fan 12 may act as the wind pressure forward through the wind pressure hole 11 of the casing 1 and the wind pressure hole 21 of the sliding casing 2. That is, the wind pressure holes 11 and 21 may serve as a passage for transmitting the wind pressure of the fan 12, and may not be completely perforated in a limit capable of performing such a role.

Attention is drawn to the fact that the wind pressure reaching the plurality of nozzles 4 by driving the fan 12 disperses the fluid sprayed from the plurality of nozzles 4 depending on the length of the casing 1, FIG. 1. As shown in FIG. 3, the sliding casing 2 serves to variably extend the length of the casing 1. The sliding casing 2 is coupled with the casing 1 to be movable to protrude forward of the casing 1, as shown in FIG. 3 (b), and transmits the wind pressure forward.

For example, the sliding casing 2 may be inserted into the wind pressure hole 11 inside the casing 1 (see FIG. 3A).

That is, when the sliding casing 2 is extended in front of the casing 1 as shown in FIG. 3B, the path through which the wind passes by the fan 12 becomes long, and thus the straightness of the wind becomes stronger. Therefore, when the sliding casing 2 is extended in this way, it is possible to reduce the tendency of particles of fluid sprayed through the plurality of nozzles 4 to be dispersed more than necessary by the wind pressure, thereby increasing the injection distance.

On the contrary, when the sliding casing 2 is inserted into the wind pressure hole 11 of the casing 1 as shown in FIG. 3A, the path through which the wind by the fan 12 passes is shortened. It will spread out and disperse before going straight. Therefore, when the sliding casing 2 is inserted into the casing 1 as described above, the injection distance may be reduced because particles of the fluid sprayed through the plurality of nozzles 4 are diffused by the wind pressure.

In summary, when the sliding casing 2 is extended in front of the casing 1, the straightness of the injection becomes stronger, and when the sliding casing 2 is inserted into the casing 1, the diffusion of the injection becomes stronger. Through this, it is possible to adjust the sprayed distance according to the situation of use site.

Next, the structure of the piping 3 is examined.

The pipe 3 is supplied with the fluid and is provided in the sliding casing 2. That is, the pipe 3 is configured to deliver a fluid supplied to the plurality of nozzles 4 so that the plurality of nozzles 4 can spray the fluid by receiving the fluid. The pipe 3 may be provided in the sliding casing 2 so that the fluid sprayed from the plurality of nozzles 4 may receive the air pressure transmitted from the fan 12.

1 and 2, the pipe 3 may be provided in a form extending along the circumference of the sliding casing 2 at the front end of the sliding casing 2. As such, spraying fluid from a plurality of nozzles inward from the periphery of the front end of the sliding casing 2 may be effective to inject fluid particles forward through the wind pressure passing through the wind pressure holes 11 and 21.

However, the pipe 3 is not always provided in such a form, and may be provided on the inner space around the sliding casing 2 at the front end of the sliding casing 2. In this case, a plurality of nozzles 4 may be arranged in both the circumferential direction and the center direction of the sliding casing 2 from the pipe 3 so that the fluid is sprayed.

For example, the pipe 3 may be provided in the circumferential direction of the sliding casing 2, and a plurality of pipes 3 may be provided inward from the circumference of the sliding casing 2. This is to allow the fluid particles to be evenly sprayed inside the sliding casing 2 so that the fluid particles can receive the wind pressure acting as a whole on the wind pressure holes 11 and 21.

For example, the pipe 3 may include two of the circumferential pipe 33 and the central pipe 34. 1 and 2, the circumferential pipe 33 may be provided along the circumference of the wind pressure hole 21 of the sliding casing 2, and the center pipe 34 may be provided with the wind pressure hole of the sliding casing 2 ( 21 may be provided with a shorter length than the circumferential pipe 33 on the inner side of the circumference.

In this way, the circumferential pipe 33 and the central pipe 34 each provided with the plurality of nozzles 4 are separated and disposed in two places on the circumferential side and the center side of the sliding casing 2, so that the plural nozzles 4 as in the prior art. The fluid particles sprayed from) were sprayed only near the circumference of the sliding casing 2, and the empty space in which there was no fluid particles and only the wind pressure acted on the central side was prevented from being generated. That is, the fluid particles are evenly sprayed around the circumference and the center of the sliding casing 2 through the double pipes 33 and 34, so that the injection of the fluid can be made by utilizing the wind pressure applied by the fan 12 more efficiently. It was made.

In addition, when fluid injection is required for a short distance concentrated part, the supply of fluid to the peripheral pipe 33 on the circumferential side of the sliding casing 2 is blocked and the fluid is supplied only to the central pipe 34 on the center side. The fluid particles sprayed from the plurality of nozzles 4 can be further concentrated in one place.

4 is a schematic enlarged partial view showing a plurality of pipe parts and a link mechanism not shown in FIGS. 1 to 3, and FIG. 5 is a conceptual diagram showing a driving example of a plurality of pipe parts and a link mechanism.

Pipe 3 of the fluid injection device 100 is rotatable so that the direction in which the fluid is sprayed can be changed. For example, for the rotation of the pipe 3, the pipe 3 may include a plurality of pipe parts 31 and a link mechanism 32. 4 and 5, the plurality of piping parts 31 may be divided along the circumference of the sliding casing 2. In addition, the link mechanism 32 may rotate the plurality of piping parts 31 in a predetermined angle in a predetermined direction, respectively.

In the conventional spray sprinkler, the nozzle provided in the pipe is fixed, and it is impossible to adjust the angle or direction in which the fluid is injected. On the other hand, as shown in Figures 4 and 5 in the fluid injection device 100 is configured to enable a predetermined rotation for each of the plurality of pipe parts 31 divided by dividing the pipe (3). Referring to FIG. 5, the plurality of piping parts 31 rotate together with the movement of the link mechanism 32, thereby adjusting the angle or direction of the fluid sprayed through the plurality of nozzles 4.

For example, the link mechanism 32 may push or pull each middle of the plurality of piping parts 31 so that each of the plurality of piping parts 31 may be rotated in the predetermined direction. For example, referring to FIGS. 4 and 5, the link mechanism 32 includes a link 321 and a link 321 respectively connected to the plurality of pipe parts 31 so as to be rotatable about an axis parallel to the axis of rotation. It may include a cylinder 322 to push or pull. As a result, the plurality of pipe parts 31 may move while maintaining the same angle at the same time by the cylinder 332 mounted through the link 321, the cylinder rod 323, and the like for each of the plurality of pipe parts 31. have.

However, the link mechanism 32 mounted on each of the plurality of piping parts 31 rotates all of the plurality of piping parts 31 to the inside of the sliding casing 2 or to the outside of the sliding casing 2 or the like. Although all of the plurality of piping parts 31 can be driven uniformly, the present invention is not limited to this driving method and may be set to individually drive each of the plurality of piping parts 31.

In addition, the cylinder 322 included in the link mechanism 32 may be an air cylinder type, but is not limited thereto. A screw jack or a worm gear type may also be adopted.

Here, the predetermined direction may be a direction in which a line connecting each end of each of the plurality of piping parts 31 is rotated as a rotation axis. For example, referring to FIG. 5, a driving example of the link mechanism 32 for one of the plurality of piping parts 31 is shown in stages, and one of the plurality of piping parts 31 connects a line connecting both ends thereof. When the link mechanism 32 is pushed (FIG. 5 (a)) as the rotary shaft, the link mechanism 32 is rotated clockwise, and when the link mechanism 32 is pulled (FIG. 5 (b)), it is rotated counterclockwise. This driving direction may be the predetermined direction described above.

In addition, within the range of a predetermined angle may mean a range of angles that can be rotated in a predetermined direction within the range that can be pushed or pulled by the link mechanism (32). As the range of this predetermined angle becomes larger, it may be easier to adjust the straightness or the diffusivity of the fluid, but the angle should be set within the operating range of the link mechanism 32. For example, if only the linear motion that the link mechanism 32 pushes and pulls is possible, the linear motion alone may limit the range of angles at which one of the plurality of pipe parts 31 is rotated.

Through the configuration of the plurality of divided pipe parts 31 and the link mechanism 32 attached to each of them, the fluid sprayed by spreading or narrowly concentrating the fluid sprayed from the plurality of nozzles 4 as necessary. The device 100 can be used more variably.

For reference, FIGS. 1 to 3 omit illustrations of the plurality of piping parts 31 and the link mechanism 32. 4 and 5, only the circumferential pipe 33 is shown, and the illustration of the central pipe 34 is omitted. However, it is noted that the embodiments of FIGS. 1 to 3 and the embodiments of FIGS. 4 and 5 are not clearly distinguished. For example, the fluid injection device 100 includes both a circumferential pipe 33 and a center pipe 34, and the circumferential pipe 33 may be divided into a plurality of pipe parts 31, and may include The link mechanism 32 may be connected to the pipe 33. That is, an embodiment in which the embodiments of FIGS. 1 to 3 and the embodiments of FIGS. 4 and 5 are combined is also possible.

Next, the structure of the some nozzle 4 is examined.

The plurality of nozzles 4 are sprayed by receiving the fluid from the pipe 3 and are installed along the pipe 3 so that the air pressure acts on the fluid to be sprayed. The installation of wind pressure on the fluid to be sprayed, for example, when the pipe 3 is provided along the circumference of the sliding casing 2 is suitable between the inward direction of the sliding casing 2 and the front of the sliding casing 2. It may mean that a plurality of nozzles (4) are installed in the pipe (3) so that the fluid can be sprayed in the direction. That is, it is preferable that the plurality of nozzles 4 are installed in the pipe 3 in a position and a direction in which the wind pressure acts most efficiently on the fluid to be sprayed to be sprayed forward.

Next, the structure of the fluid line 51, the air line 52, and the mixer 53 is examined.

The fluid line 51 may supply a fluid to the pipe 3, and the air line 52 may supply air to the pipe 3. In addition, the mixer 53 may serve to mix air and fluid and supply the pipe 3.

Unlike the conventional method in which only the water line is supplied to the pipe connected to the nozzle, the fluid spray device 100 includes the fluid line 51 as well as the air line 52 and mixes the mixture through the mixer 53. By being able to supply to the piping 3, the fine spray which mixed the fluid and air is attained. In addition, due to mixing with the high pressure air, the angle at which the fluid particles sprayed from the plurality of nozzles 4 are dispersed becomes larger, and the air may be sprayed farther than when it is sprayed without mixing.

At this time, the air line 52 and the fluid line 51 may be selectively on / off (on / off). That is, only the fluid line 51 may be turned on so that only fluid is supplied to the pipe 3. On the contrary, the fluid line 51 is turned off and the air line 52 is turned on so that only air is supplied to the pipe 3. You can also

In particular, only the air line 52 may be turned on so that the pipe 3 and the plurality of nozzles 4 may be cleaned. After use of the fluid spray apparatus 100, recycled water containing impurities may remain in the pipe 3 and the plurality of nozzles 4. It can accumulate at the same entrance as to form a scale. In order to suppress the occurrence of such a scale, the fluid line 51 is turned off with respect to the pipe 3 and only the air line 52 is turned on. Then, high-pressure air is blown for a predetermined time to remove a plurality of residues such as recycled water. By discharging all outside the nozzle 4, the piping 3 and the some nozzle 4 can be kept clean. That is, by selectively turning on only the air line 52, the cleaning function of the pipe 3 and the plurality of nozzles 4 may be performed to extend its life.

Next, the structure of the left-right rotating mechanism 6 and the up-down rotating mechanism 7 is examined.

The left and right rotating mechanism 1 can rotate the casing 1 from side to side in the vertical direction. 1 and 2, for this purpose, the left and right rotating mechanism 1 may include a turntable bearing 61 connected directly or indirectly with the casing 1 to rotate the casing 1 to the left and right.

For example, referring to FIGS. 1 and 2, a turntable bearing 61 mounted on the upper portion of the worm gear 62 by mounting the worm gear 62 inside the base 8 and using the motor 63 to drive the worm gear 62. By rotating, the frame 71 connected to the turntable bearing 61 and supporting the casing 1 may be rotated from side to side to allow the casing 1 to be rotated.

Accordingly, the left and right rotation mechanism 1 may further include a configuration of the worm gear 62 and the motor 63 in addition to the turntable bearing 61. In addition, the base 8 may not be a configuration included in the left and right rotation mechanism 1, but may be a configuration that serves as a foundation for supporting the entire fluid spraying device 100 on the bottom surface.

In addition, the up-and-down rotation mechanism 7 can rotate the casing 1 up and down in the lateral direction. 1 and 2, the vertical rotation mechanism 7 is a frame 71 for rotatably fixing the casing 1 about the above-mentioned axis, and the casing 1 about the above-mentioned axis by linear motion. It may comprise a screw jack 72 connected to the casing 1 to lift it up or pull it down.

For example, referring to FIGS. 1 and 2, when the rotation of the motor 74 provided for the up and down rotation is transmitted to the worm gear 73, the linear movement of the screw jack 72 is performed through the worm gear 73. . When the linear movement of the screw jack 72 is transmitted to the casing 1 through a part connected with the casing 1, the casing 1 attached to the frame 71 can move up and down about the axis described above. have.

Accordingly, the vertical rotation mechanism 1 may further include the configuration of the worm gear 73 and the motor 74 in addition to the configuration of the frame 71 and the screw jack 72.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
