In this case, the fluid filling unit 191 may receive the fluid from the external fluid storage unit and supply the fluid to the foreign matter storage unit 150. In addition, the fluid filling unit 191 may be provided with a switch to stop or sustain the supply of the fluid in accordance with the external control signal.

The dust collecting system 100 may include a controller 192. In this case, the controller 192 may control the fluid supply unit 191 based on the value measured by the water level measurement sensor 180. In addition, the controller 192 may control the fluid supply unit 141 to supply the fluid to the nozzle unit 143.

On the other hand, looking at the operation of the dust collecting system 100 as described above, in the work space (S), the operator can perform a work that generates foreign substances such as dust, such as painting, grinding work. At this time, the fine particles of the foreign matters are mixed in the gas of the working space (S), may cause environmental pollution when leaked to the outside. Therefore, the dust collection system 100 can be operated to prevent this.

Specifically, when operating the drive unit 130 may suck the gas of the workspace (S) into the suction pipe (110). In this case, the filter unit 120 may first remove foreign substances contained in the gas.

When the foreign matter is first removed from the filter unit 120 as described above, the filter unit 120 may be replaced according to the time elapsed or the amount of the filtered foreign matter. At this time, the dust collecting system 100 is installed in the filter unit 120 or the suction pipe 110, and the like to measure the amount of foreign matter in the filter unit 120 (not shown) and the value measured by the sensor unit It is also possible to further include an alarm unit (not shown) for emitting a signal to the outside on the basis. Specifically, the sensor unit measures the amount of foreign substances by irradiating light or laser to the filter unit 120, or when the filter unit 120 is formed of metal, measuring the resistance of the filter unit 120 to measure the amount of foreign substances. It is also possible. In addition, when the value measured by the sensor unit corresponds to a preset value, the alarm unit may inform the outside of the replacement of the filter unit 120 by sound or image. In this case, the sensor unit is not limited to the above, and may include all devices and structures for measuring the amount of foreign matter filtered by the filter unit 120. However, hereinafter, the description will be made with reference to a case where the sensor unit is not provided for convenience of description.

The gas filtered by the filter unit 120 as described above may move to the outlet O through the suction pipe 110 according to the operation of the driving unit 130. In this case, the fluid injection unit 140 may inject a fluid into the suction pipe 110.

In detail, when the fluid supply unit 141 operates, the fluid may move to the first nozzle unit 144 and the second nozzle unit 145 through the guide unit 142. In this case, the fluid may be a fluid stored in the foreign matter storage unit 150. Thereafter, the first nozzle unit 144 may inject fluid from the outer circumferential surface of the suction pipe 110 toward the center of the suction pipe 110. In addition, the second nozzle unit 145 may inject fluid from the center of the suction pipe 110 toward the outer circumferential surface of the suction pipe 110. While the fluid is injected as described above, the gas may move toward the inner circumferential surface side of the suction pipe 110 along the outer surface of the second nozzle body 145a. In particular, the second nozzle body 145a may collect foreign substances contained in the gas into the space between the second nozzle body 145a and the suction pipe 110 through the movement of the gas.

When the fluid is injected as described above, foreign matter in the gas may collide with the fluid. In this case, the first nozzle unit 144 and the second nozzle unit 145 may form small fluid particles by spraying a fluid. Therefore, the foreign matter may be heavy by colliding with the fluid of the small particles may fall into the foreign matter storage unit 150 through the outlet (O) of the suction pipe 110.

In particular, when the first nozzle unit 144 and the second nozzle unit 145 inject the fluid as described above, the fluid sprayed by the first nozzle unit 144 and the fluid sprayed by the second nozzle unit 145 are mutually different. It can be sprayed in a staggered direction. Specifically, the fluid is injected from the second nozzle unit 145 in the space between the adjacent first nozzle units 144, and the fluid is injected from the first nozzle unit 144 in the space between the adjacent second nozzles 145b. Can spray Therefore, the first nozzle unit 144 and the second nozzle unit 145 may inject the fluid to the areas that do not overlap each other.

During the process, some of the foreign matters may be injected into the foreign matter storage unit 150 through the outlet O together with the gas without colliding with the fluid. In this case, the outlet O may be discharged to the outside of the foreign matter storage unit 150 because it is spaced apart from the fluid surface inside the foreign matter storage unit 150 by a predetermined interval. The shielding unit 160 may completely absorb the foreign substance leaked as described above to adsorb foreign substances or drop the foreign substances to the fluid side of the foreign substance storage unit 150.

The water level detection sensor 180 in which the above operation is performed may detect the level of the fluid in the foreign matter storage unit 150. In particular, when the above operation is continuously repeated, the fluid level inside the foreign matter storage unit 150 may be less than the minimum level by evaporating the fluid inside the foreign matter storage unit 150.

In this case, when the level of the fluid is detected by the first level sensor 181, the controller 192 may determine that the level of the fluid in the foreign matter storage unit 150 is the lowest level. The control unit 192 may operate the fluid filling unit 191 to supply the fluid into the foreign matter storage unit 150. Such supply may be performed until the level of the fluid is detected in the second level sensor 182. In particular, the control unit 192 maintains the fluid level of the foreign matter storage unit 150 at the maximum level by not operating the fluid filling unit 191 when the level of the fluid is detected by the second level sensor 182. The above operation can be repeated again.

Therefore, the dust collecting system 100 can effectively remove the foreign matter generated in the workspace (S). In addition, the dust collecting system 100 may prevent contamination of the surrounding environment due to harmful substances by not leaking foreign substances to the outside.

The dust collecting system 100 may remove most of the foreign matters simply and through the first nozzle unit 144. In addition, the dust collecting system 100 assists the first nozzle unit 144 through the second nozzle unit 145 to prevent the foreign matters from the area that the first nozzle unit 144 does not cover out, thereby increasing dust collection efficiency. You can increase it.
