| 摘要 | An aerosol spray device of a type capable of holding an aerosol can in position for periodic operation in response to contact with a motor-driven camming means which contacts the upwardly disposed spray nozzle thereon to activate a valve disposed therebeneath. A unitary molded casing element forms a battery chamber which is externally accessible through an opening in a rearwardly disposed wall, the battery chamber shielding batteries disposed therein from any stray vapors within the casing element. The casing element forms track means slidably supporting an adjustably located chassis which mounts the timing means, as well as the motor-driven camming means. By shifting the chassis relative to the casing element, the period of time during a given operational cycle in which the nozzle is contacted and moved to spraying position is varied, thereby varying the amount of spray dispensed. The timing means includes a capacitor which is charged by the motor while it is coasting to a stop at the completion of a cycle, the condensor being discharged at the beginning of the next timing cycle to conserve battery power. | ||||||
| 权利要求 | 1. In a device for periodically operating an aerosol dispenser can, including a timing circuit, and motor-driven camming means positioned to repeatedly contact a spray nozzle to operate a valve associated therewith, the improvement comprising: a casing element including first and second angularly disposed outer walls, track means carried by said casing element having a principal axis parallel to one of said walls, said casing element defining an enclosure, a chassis element slideably carried by said track means for adjustable movement relative to the other of said walls, said motor-driven camming means being carried by said chassis, said camming means including at least one lobe having a substantially arcuate path of motion, movement of said chassis serving to translationally shift said arcuate path to vary the length of that portion of the path during which said spray nozzle is contacted; means on said chassis projecting outwardly of said casing element to permit manual adjustment outwardly of said enclosure of the position of said chassis element relative to said casing element without opening the latter, said last mentioned means including a projection on said chassis, and a lever pivotally connected to said projection and a fixed point on said casing element. |
