Title:
SUCTION DEVICE AND NOZZLE DEVICE
Document Type and Number:
Japanese Patent JP3889732
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a suction device and a nozzle device of which the structure is simple, in which a fluid is automatically sprayed to an object from a nozzle and at the same time the fluid hitting against the object is sucked, when the nozzle is brought close to the object or abutted to the object, when a suction operation is performed for the fluid and in which the fluid is automatically prevented from being sprayed to the outside of the nozzle, when the nozzle is separated from the object.
SOLUTION: The suction device 1 is provided with a fluid nozzle 12 spraying the fluid toward a nozzle opening end in the nozzle 11, and when the opening 13 of the nozzle 11 is opened, the outside air 300 taken into the nozzle 11 from the opening 13 defeats the fluid sprayed from the fluid nozzle 12, enabling the fluid to be sucked together with the outside air 300 without being sprayed to the outside from the opening 13 of the nozzle 11. In the device, further, when the amount of the outside air sucked into the nozzle 11 is reduced by bringing the opening 13 of the nozzle 11 close or abutted to the object, the fluid sprayed from the fluid nozzle 12 defeats the outside air, enabling the fluid to be sprayed to the object and, at the same time enabling the fluid hitting against the object to be sucked.
