Abstract
Aspects of the disclosure are directed to methods and/or apparatuses involving an apparatus having a channel, an actuator, a mechanical stop, and a dial having nozzles and a gear. The dial is operable to rotate for selectively aligning each of the respective nozzles with the channel. The gear has a plurality of cogs and recessed regions between adjacent ones of the cogs, and is configured with the mechanical stop to prevent movement of the actuator when the dial is positioned such that none of the nozzles are aligned with the channel.
Claims20
An apparatus comprising:
- a liquid supply channel;
- a rotatable dial having a plurality of nozzles arranged about a surface of the rotatable dial in a common plane therewith and separated from one another by a portion of the rotatable dial, the rotatable dial being configured to selectively align each of the respective nozzles with the channel for receiving and spraying propelled liquid received via the channel in a common direction perpendicular to the common plane and the surface of the rotatable dial;
- an actuator configured and arranged to release the propelled liquid into the channel by actuating a valve;
- and
- a locking mechanism including a gear coupled to rotate with the rotatable dial, the gear having cogs and recessed regions between the cogs, and configured with the rotatable dial to:
- in response to the rotatable dial being positioned with the nozzles out of alignment with the channel, prevent actuation of the valve and block delivery of the propelled liquid to the channel by preventing movement of the actuator;
- and
- in response to the rotatable dial being positioned with one of the nozzles aligned with the channel, facilitate movement of the actuator for actuating the valve and delivering the propelled liquid to the one of the nozzles via the channel.
