Spraying device

摘要

The present invention relates to a automated spraying device for spraying an enclosure with a liquid cleanser, the device having,—a reservoir (16) for containing the liquid cleanser,—a pump (14) in fluid communication with the reservoir, and—a movable spray head (15) having an outlet orifice through which cleanser from the reservoir can be expelled during operation of the pump if there is such liquid cleanser in the reservoir. Said spraying device also contains an electrical motor drive mechanism (12) for sequentially operating th pump (14) and moving the spray head (15) to modify the direction of the spray there from, such that the spray head is not simultaneously spraying and moving. Furthermore, the spray head is suitable for producing an aerosol whereby the Dv50 of the aerosol is in the range of from 30 to 70 micron.

1. An automated spraying device for spraying an enclosure with a liquid cleanser, the device having,
a reservoir(16) suitable for containing the liquid cleanser, a pump (14) in fluid communication with the reservoir, a rotatable spray head (15) having an outlet orifice through which cleanser from the reservoir can be expelled during operation of the pump (14) if there is such liquid cleanser in the reservoir, wherein the spraying device also contains an electrical motor drive mechanism (12) for sequentially operating the pump (14) and moving the spray head (15) to modify the direction of the spray there from, such that the spray head (15) is not simultaneously spraying and moving, in that the spray head (15) is suitable for producing an aerosol whereby the Dv50 of the aerosol is in the range of from 30 to 70 micron, and wherein sequential spraying and moving operations are repeated five times during a full spray cycle, such that during the full spray cycle, the spray head (15) rotates over an angle of 360 degrees, while delivering a total of five spray shoots.
