Fluid dispensers dispense fluids using a wide range of methods. Some fluid dispensers may be manually actuated by a user physically contacting a mechanism (e.g., a lever), while others may be automatically actuated (e.g., using a motor) when a user's hand is sensed by a sensor. For an automatically actuated fluid dispenser, a user may initiate the fluid dispensing operation, only to move their hand away from the fluid dispenser after the fluid dispenser decided to dispense the fluid. This may result in the dispensed fluid being dripped onto a drip tray or the floor. Additionally, at the conclusion of a dispensing cycle, the tail end of the fluid stream may unintentionally drip onto the drip tray or the floor. These drips may be unsightly, require additional maintenance, and potentially result in a slippery surface. As a result, it is desirable to prevent this fluid from being dripped onto the drip tray or the floor.
Additionally, it would be beneficial to draw a user closer to the fluid dispenser, while avoiding background noise (such as movement beyond a predetermined distance). While several fluid dispensers have been made and used, it is believed that no one prior to the inventors has made or used the invention described in the appended claims.

I. Exemplary Fluid Dispensers and Methods of Operation
A. First Exemplary Fluid Dispenser
Body (12) includes a front panel (38) and a receptacle (40). Front panel (38) is pivotable relative to receptacle (40), via hinges (42), between a closed configuration (shown schematically in
Pump (18) is configured to receive fluid from fluid source (14). While pump (18) is shown as a peristaltic pump in
As shown in

As shown in
Third button (86) may be actuated to place fluid dispenser (10) in a sleep mode; and may be actuated a second time to resume dispensing. Sleep mode may allow for cleaning or other maintenance of fluid dispenser (10). The sleep mode may allow for display (30) to continue displaying message(s); but prevent the fluid from being dispensed. This may be beneficial when a maintenance person or other user is interacting with fluid dispenser (10) and does not desire to have fluid dispensed. Fluid dispenser (10) may empty all of the residual fluid from tubing back into fluid cartridge (62) upon initiation of sleep mode. In some versions, an internal counter (not shown) may be automatically reset; while in other versions, third button (86) may be actuated and held for a predetermined time to reset the internal counter of fluid dispenser (10). The internal counter may be used to determine a volume of usable fluid remaining in fluid cartridge (62). Upon priming of fluid dispenser (10), optical sensor (60) may be used to position the leading edge of the fluid so that fluid dispenser (10) is ready for the first dispensing. For example, the leading edge of fluid may be placed adjacent to optical sensor (60), or the leading edge of the fluid may be located within nozzle assembly (24), so that the fluid is ready to be dispensed. Instructions for use may be displayed to the maintenance person or other user, such as on a decal on an inner surface of front panel (38) or otherwise.
Controller (32) is in communication with pump (18), near field laser range finder (26), far field laser range finder (28), and optical sensor (60). Controller (32) may additionally provide remote monitoring of service intervals as described below with reference to
Near and far field laser range finders (26, 28) are shown in
Far field laser range finder (28) is configured to sense a presence of a user at a distance that is greater than the distance sensed by near field laser range finder (26). Far field laser range finder (28) senses a user passing by and attracts them to use fluid dispenser (10), as will be described in greater detail below with reference to
B. Second Exemplary Fluid Dispenser
A second exemplary fluid dispenser (110) is schematically shown in
Body (112) is configured to be mounted on a stand (188). Body (112) may include a cap (not shown). Stand (188) includes an upper enclosure (190) and a base (192). As shown, body (112) of fluid dispenser (110) may include at least one coupling feature, shown as tightening members (178). Tightening members (178) may tighten, pinch, and align body (112) of fluid dispenser (110) with upper enclosure (190). Upper enclosure (190) of stand (188) includes at least one coupling feature, shown as rigid members (194). Rigid members (194) are configured to couple with tightening members (178) to align body (112) with stand (188).
C. Second Exemplary Nozzle Assembly
Nozzle (214) includes opposing proximal and distal ends (232, 234). Nozzle connector (216) fluidly couples proximal end (232) with tubing (22). Fluid is dispensed to nozzle (214) from tubing (22). Nozzle (214) is shown as a metal tube that eliminates crevices to reduce the effect of dried fluid forming around and within distal end (234). Distal end (234) of nozzle (214) may include a sharp tip (236) that is configured to reduce the effect of dried fluid forming around and within second end (234). Over time, without sharp tip (236), dried solution may otherwise reduce the inner diameter of nozzle (214) and affect the ability of the fluid to be dispensed therethrough. For example, a partially clogged distal end (234) may reduce the usable inner diameter of nozzle assembly (24), which may cause the fluid to be dispensed at a variety of angles. Dispensing the fluid at a variety of angles may cause the fluid to not be dispensed in the expected location or quantity. For example, this may prevent the fluid from being entirely captured by the hand(s) of the user. Providing sharp tip (236), or otherwise configuring nozzle (214) to avoiding the formation of dried fluid, may thus provide consistent, predictable dispensation of fluid over repeated uses of fluid dispenser (10).
D. First Exemplary Method of Use
A method (310) of operating a fluid dispenser (10) is described with reference to
Conversely, in response to sensing the presence of the object, at step (314), method (310) includes determining that the object remains within the predetermined distance (being captured by near field laser range finder (26)) for a first predetermined amount of time using controller (32). This may increase the likelihood that the object initially sensed desires the fluid from fluid dispenser (10). In some versions, the predetermined time may be about 100 milliseconds; however, this time may vary. Particularly, hand placement under arm (44) is sensed using near field laser range finder (26).
In response to determining the object remains within the predetermined distance for the first predetermined amount of time, at step (316), method (310) includes activating pump (18) of fluid dispenser (10) for a second predetermined amount of time or for a predetermined number of rotations. This predetermined number of rotations may be a predetermined number of rotations of pump (18), which may in turn provide dispensation of a predetermined volume of fluid based on the number of rotations. In some versions, the predetermined number of rotations may be about 10 rotations; however, this number of rotations may vary. Dispensing may be achieved by operating pump (18) (e.g., a calibrated peristaltic pump) using stepper motor (20). Stepper motor (20) moves in a forward direction (clockwise or counterclockwise) for a predetermined number of degrees to dispense the fluid.
At step (318), method (310) includes controller (32) determining if the object remains within the predetermined distance of the near field laser range finder (26) until the completion of the predetermined amount of time or a predetermined number of rotations. At step (320), if the object remains within the predetermined distance of the near field laser range finder (26) for the entire predetermined amount of time or the predetermined number of rotations, the full volume is fluid is dispensed. However, at step (322), if the object does not remain within the predetermined distance of near field laser range finder (26) for the entire predetermined amount of time or the predetermined number of rotations, the dispensing terminates prior to the predetermined amount of time or a predetermined number of rotations. As a result, only a partial portion of the full volume is fluid is dispensed.
At step (324), method (310) includes reversing operation of pump (18) for a second predetermined number of rotations to reduce fluid from being dispensed. In some versions, the second predetermined number of rotations may be about 3 rotations; however, this number of rotations may vary. Reversing operation of pump (18) may be performed using stepper motor (20) as instructed by controller (32). After dispensing is complete or terminated prematurely, stepper motor (20) switches to a reverse direction (the other of clockwise or counterclockwise) for a predetermined number of degrees to reduce or altogether eliminate unintended drips between uses. The reverse direction is opposite to the forward direction. This reversing of stepper motor (20) effectively pulls at least some of the fluid back into fluid dispenser (10) that may otherwise unintentionally drip out of nozzle assembly (24) onto drip tray (46) or the floor. Particularly, if the user's hand moves away from fluid dispenser (10) before the dispensing cycle completes, then pump (18) immediately reverses to prevent unintended drips. This utilizes the fast action of pump (18) (shown as a peristaltic pump) and stepper motor (20), based on the sensing from near field laser range finder (26).
After reversing operation of pump (18), at step (326), method (310) includes delaying for a second predetermined amount of time. In some versions, the second predetermined amount of time may be about 500 milliseconds; however, this time may vary. In some versions, if fluid dispenser (10) is not utilized for a predetermined amount of time (e.g., 9 hours), controller (32) may reverse operation of pump (18) using stepper motor (20) to retract the fluid to a position before (i.e., upstream) of the rollers (52) of pump (18). This may prevent evaporation and drying of the fluid in tubing (22). Upon activation of pump (18), at step (316), the fluid may be moved to nozzle assembly (24) for subsequent dispensing.
E. Second Exemplary Method of Use
A method (410) of operating a fluid dispenser (10) that includes far field laser range finder (28) and display (30) is described with reference to
At step (414), method (410) includes activating display (30) on fluid dispenser (10) for a predetermined amount of time, to attract the user to the display (30). In some versions, the predetermined time may be about 5 seconds. To attract the user, display (30) may show a drip display on a linear red, green, and blue (RGB) screen. Alternatively, display (30) may show any other suitable text and/or graphics to try to attract the user to interact with fluid dispenser (10). In the event that the user moves closer to fluid dispenser, at step (416), method (410) includes sensing the hand of the user located within a second predetermined distance from near field laser range finder (26). The first predetermined distance is greater than the second predetermined distance.
In response to sensing the hand of the user located within the second predetermined distance from near field laser range finder (26), at step (418), method (410) includes activating dispensing message on display (30) while dispensing fluid from nozzle assembly (24) of fluid dispenser (10). After completing step (418), at step (422), method (410) includes reversing operation of pump (18) for a second predetermined number of rotations to reduce fluid from being dispensed, similar to step (324). At step (424), method (410) includes initiating a predetermined delay.
Conversely, in response to not sensing the hand of the user located within the second predetermined distance from near field laser range finder (26) at step (416), method (410) includes activating a non-dispensing message on display (30) at step (420). For example, this non-dispensing message may include a yellow triple flash on display (30). After step (420) of activating the non-dispensing message, method (410) may initiate the predetermined delay at step (424). In some versions, the predetermined delay at step (424) may be about 3 seconds, after which a user may reactivate fluid dispenser (10) as described above in step (412) using far field laser range finder (28).
F. Third Exemplary Method of Use
An exemplary method (510) of calibrating fluid dispenser (10) is shown and described with reference to
At step (512), upon startup of fluid dispenser (10), controller (32) may instruct stepper motor (20) to operate pump (18) in reverse to evacuate fluid from tubing (22). This clears any residual fluid from tubing (22). In some versions, tubing (22) may be optically transmissive so that optical sensor (60) may obtain an unobstructed view of fluid (554) through tubing (22). In other versions (e.g., where tubing (22) is not optically transmissive), an optically transmissive tubing segment (not shown) may be interposed between terminal ends of tubing (22) and thereby be in fluid communication with tubing (22), with optical sensor (60) being positioned at this optically transmissive tubing segment, so that optical sensor (60) may obtain an unobstructed view of fluid (554). At step (514), controller (32) may instruct optical sensor (60) to adjust the gain on optical sensor (60) to a point just prior to reaching detection. In other words, increasing the gain on optical sensor (60) may increase the sensitivity of optical sensor (60). This may minimize, or altogether negate, effects caused by variations in the optical transmissivity of tubing (22) due to manufacturing variability, aging, etc.
At step (516), controller (32) may instruct stepper motor (20) to operate pump (18) in the forward direction until fluid (554) is detected by optical sensor (60). This movement of fluid (554) is shown in
At step (522), controller (32) may instruct stepper motor (20) to operate pump (18) in the forward direction the predetermined amount as determined in step (516) and stored in step (518). This is shown in
G. Exemplary System
Wireless module (616) may be in communication with a network (618). Network (618) may include a wired network or a wireless network (e.g., a WiFi network). Network (618) may communicate with at least one device (shown as first and second devices (620a, 620b)). For example, a maintenance person or other user may add fluid dispensers (10) onto network (618) using an application (622) (
