Abstract
A suction device and a nozzle device that have a simple structure and where, when suction work is performed with a nozzle that is close to or in contact with an object, a fluid is automatically jetted from a nozzle toward the object and the fluid that struck the object can be absorbed. Further, when the nozzle is moved away from the object, jetting the fluid toward the outside of the nozzle is automatically stopped. In a suction device (1), a fluid nozzle (12) for jetting a liquid toward a nozzle opening end is provided in a nozzle (11). When an opening (13) of the nozzle (11) is opened, outside air (300) sucked from the opening (13) into the nozzle (11) overcomes the fluid jetted from the fluid nozzle (12), making it possible that the fluid is sucked together with the outside air (300) without the fluid jetted from the opening (13). When an amount of outside air sucked into the nozzle (11) is reduced by bringing the opening (13) close to or into contact with the object, a fluid jetted from the fluid nozzle (12) overcomes the outside air and is jetted to the object, making it possible that the fluid struck the object is sucked.

At first, connect the nozzle 11 of spray nozzle device 10, connect the fluid tip 12 of spray nozzle device 10, spray nozzle device 10 so is installed on suction device body 100 at the front end of fluid supply line 102 at the front end of the attraction flexible pipe 101 of suction device body 100.
Then, in primary tank 120, accommodate the water 200 of scheduled volume after, operation control panel 170 drives fan motor 141.In addition, in embodiment one, utilize to attract control device 142 that the attraction vacuum of fan motor 141 is made as about 19kPa.By driving this fan motor 141, extraneous air 300 is inhaled into from the opening 13 that is arranged on the nozzle 11 that attracts flexible pipe 101 front ends.At this moment, the extraneous air amount that sucks from the opening 13 of nozzle 11 is approximately 1.0m
3/ minute.By sucking this extraneous air 300, the air in the primary tank 120 is directed in the separator 143.At this, in separator 143,, can utilize the principle of cyclone separator to be separated into gas (air) and liquid (water 200), thereby water 200 can not be inhaled in the fan motor 141 even be mixed with water 200 in the described air yet.The extraneous air (air) that is aspirated by fan motor 141 passes through passage 130 and through fan motor 141, is discharged to the outside from predetermined exhaust outlet.
In addition, meanwhile, operation control panel 170 drives pump 132.Draw the water 200 that is housed in the filter 121 by the driving of this pump 132, and be incubated under preferred temperature by heater 160, the water of this insulation (warm water) 200 is supplied to fluid tip 12 by fluid supply line 102.In addition, in embodiment one, utilize pressure control device 133 that the hydraulic pressure of pump 132 is made as roughly 0.3MPa.At this moment, the flow of the water 200 that sprays from the jet 17 of fluid tip 12 is roughly 50 liters/hour.
Under the state that the opening 13 of this nozzle 11 opens wide (with reference to Fig. 3), under the state that to be it leave from wall 150, be drawn into the extraneous air 300 in the nozzle 11 and the water 200 that sprays from fluid tip 12 is collided from the opening 13 of nozzle 11 between the opening 13 of the jet 17 of fluid tip 12 and nozzle 11, extraneous air 300 is better than the water 200 that sprays from fluid tip 12, thereby water 200 can not be ejected into the outside from the opening 13 of nozzle 11, water 200 and extraneous air 300 are inhaled into together, and are recovered in the primary tank 120.Therefore, can be not as prior art for block the preceding of water 200 so that cutoff plate etc. for example is set, to spray nozzle device 10 additional complicated structures, but can utilize the extraneous air 300 of suction to block advancing of water 200, make the water 200 that sprays from fluid tip 12 can not be ejected into the outside from the opening 13 of nozzle 11.Therefore, can simplify the formation of nozzle, reduce fault rate, can also make with low cost simultaneously.
Then, under the state of the pump hydraulic pressure of the attraction vacuum of keeping fan motor 141 and pump 132, the opening 13 that makes nozzle 11 near or be connected to wall 150 (with reference to Fig. 4), thereby the extraneous air amount in the nozzle 11 of being drawn into was lacked when opening wide than the opening 13 of nozzle 11.At this moment, the extraneous air amount that is drawn in the nozzle 11 is approximately 0.05m
3/ minute.At this, even if opening 13 is close on the wall 150, extraneous air 300 also can import in the nozzle 11 from aperture 16, so spray nozzle device 10 can move swimmingly, can reclaim sewage swimmingly.Because the extraneous air amounts that are drawn in this nozzle 11 reduce, the water 200 that sprays from fluid tip 12 is better than the extraneous air 300 in the inlet nozzle 11, thereby sprays to wall 150.And the water 200 that is ejected on the wall 150 is inhaled into, is recovered in the primary tank 120 by attracting flexible pipe 101 with extraneous air 300.
In addition, when being attached with dirt etc. on the wall 150, this dirt be injected into that water 200 on the wall 150 washes out and water 200 and extraneous air 300 together by attracting flexible pipe 101 to be inhaled into, to be recovered in the primary tank 120.Therefore, the water 200 that is ejected on the wall 150 can not trickle or drip, and dirt can be aspirated simple and reliablely, be removed in the operator's that gets wet clothes, bed clothes or floor etc.
