Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Application No. 63 / 325,480, filed on March 30, 2022, and is incorporated herein by reference in its entirety for all purposes. Technical Field

[0003] The present teachings relate to devices and methods for operating an automatic liquid dispensing device. The automatic liquid dispensing device may be useful in providing clean drinking water to animals. Clean drinking water may be achieved through different modes: filling with clean water, circulating water, emptying stale water, refilling with clean water, or a combination thereof. The modes may be achieved by using a rotating carousel and a valve assembly. Background Art

[0004] Livestock often prefer running water, freshly poured water, and filtered water to still water sitting in a bowl. This preference can be attributed to the fact that moving water is cooler and more oxygenated, and therefore tastes better; filtered water tastes fresher; the sound of running water attracts the animal's attention; or even that the animal's eyesight does not allow them to see standing water well, so they rely on their other senses. To address these needs, there are many automatic drinking fountains suitable for use by pets. Conventional pet drinking fountains face disadvantages associated with their water circulation systems, filtration systems, and refilling processes.

[0005] A challenge associated with conventional drinking fountains for livestock is the use of pumps and pipes. The pump can typically be a centrifugal pump. This pump relies on an impeller assembly to apply centrifugal force to discharge water and generate a negative pressure for introducing water. Often after tap water or well water has been used for a period of time, these drinking fountains including pumps and associated pipes have accumulation of mineral and biofilm deposits on surfaces including the inside and outside of the pump and the inside and outside of the piping, where water may contact. Users (e.g., pet owners) typically find that it is cumbersome and time-consuming to disassemble the drinking fountain and pump and rinse to remove sediment. Even more challenging is that in some drinking fountain assemblies, the pump and piping cannot be accessed for cleaning. Over time, without maintaining components, the water provided by the drinking fountain may become uninteresting to animals due to the accumulation of sediment affecting the taste of the water, and the drinking fountain may even become inoperative.

[0006] Another challenge associated with this water dispenser is the refilling process or lack of the refilling process. Generally, automatic water dispensers provide a fixed volume of circulation, or they can have a reservoir tank that automatically adds water as the water level drops. In the case of a fixed volume water dispenser, as the water evaporates and is consumed, there is less water to dilute the pollutants and the minerals and biofilm deposits collected over time. In the case of a reservoir that automatically adds water to keep the volume of the circulating water constant, the incremental clean water volume added is relatively small compared to the volume of the circulation, so the density of the pollutants increases over time. In addition, many water dispensers in these water dispensers are not provided with components that easily discharge the water of the previous circulation. Therefore, even when the owner refills the water dispenser, fresh water is combined with old, used water. Summary of the invention

[0007] The present teachings relate to a liquid dispensing device comprising: a) a serving bowl configured to retain liquid for consumption by an animal; b) a fresh tank configured to store fresh liquid therein; c) a used tank configured to store used liquid therein, wherein used liquid is liquid that has been made available for consumption by an animal; and d) a turntable having one or more circulation barrels and one or more emptying barrels, wherein the turntable is configured to rotate about its rotation axis in a first direction and in a second direction opposite to the first direction.

[0008] The present teachings relate to a liquid dispensing, circulation and emptying device comprising: a) a portion bowl which is perforated, removable and configured to allow liquid to pass therethrough and which is configured to retain liquid for consumption by an animal; b) one or more filters which are in fluid communication with the portion bowl; c) a reservoir which is configured to retain liquid and to connect water from the portion bowl to a turntable; d) a fresh tank which is configured to store fresh liquid therein; e) a used tank which is configured to store used liquid therein, wherein used liquid is liquid that has been made available for consumption by an animal; and f) a turntable having one or more circulation barrels and one or more emptying barrels, wherein the turntable is configured to rotate about its rotation axis in a first direction and in a second direction opposite to the first direction.

[0009] The present teachings may also relate to one or more methods of using the device. The device may be used in a filling mode, a circulation mode, an emptying mode, etc. or a combination thereof.

[0010] The device of this teaching can avoid the disadvantages associated with the pump and tube of the typical drinking fountain by completely avoiding the use of the pump and tube. The device of this teaching can provide a device composed of parts that are easily accessible and disassembled and can then be easily cleaned to clean the sediment from it. The device of this teaching can provide water circulation through a filtration system to capture debris and sediment so that the sediment does not accumulate on the surface of the device. The device of this teaching can include a fresh tank, a reservoir, or both that store water for later distribution to the serving bowl. The fresh tank can allow the owner to refill the fresh tank after a few days. The teaching can include a used tank. The used tank can allow liquids such as old or previously circulated liquids to be automatically emptied from the reservoir before being consumed or evaporated, allowing fresh liquid and / or circulating liquid to be refilled into the serving bowl and / or reservoir.

Typically, the turntable may function like a water wheel to transfer liquid from one area of ​​the device to one or more other areas of the device. The turntable may rotate to receive and / or distribute fresh liquid, receive and / or distribute used liquid, or both. Fresh water may be distributed from the tank via one or more actuator assemblies, valve assemblies, or both. The one or more actuator assemblies may be engaged by the rotation of the turntable in one or more directions. The direction of rotation of the turntable may be determined by the mode in which the device is operated.

[0053] The device may include one or more turntables. One or more turntables may play a role in transferring liquid within the device, function as a water wheel, or both. One or more turntables may transfer water from one or more tanks to one or more serving bowls, from one or more tanks to one or more spouts, from a reservoir to a spout funnel, from a reservoir to a channel, from a reservoir to a tank, etc., or any combination thereof. One or more turntables may have any shape that allows it to rotate, collect and distribute liquids, semi-solids and / or solids. One or more turntables may have a substantially and / or partially annular, cylindrical, spherical, oval, hemispherical, cubic, conical, pyramidal, etc., three-dimensional shapes, or any combination thereof. For example, the turntable may have a shape similar to a cross-section of an annular cylinder and / or a spherical ring. The cross-section may be taken perpendicular to the axis of rotation of the turntable. One or more turntables may be a single turntable capable of rotating in one or more (e.g., two) directions. One or more turntables may be two or more turntables capable of rotating in one direction. The turntable can include an outer peripheral wall, an inner peripheral wall, a bottom surface, a track, a track plane, one or more barrels, one or more barrel openings, one or more barrel spouts, one or more tabs, one or more frames, or any combination thereof. The turntable can include one or more barrels integrated therein (e.g., a single-piece turntable), or can include one or more frames (e.g., a multi-piece turntable) to which one or more barrels are attached. The frame can be a single-piece or multi-piece unit. For example, the frame can be molded. As another example, the frame can be composed of a plurality of links. The link can be similar to a chain link that defines a gap for a barrel. The single-piece turntable can be advantageous in providing simplicity of manufacturing, assembly, and disassembly. The multi-piece turntable can be advantageous in providing flexibility in the size (e.g., volume) of the barrel, adapting to different emptying and circulation speeds and volumes.

[0054] One or more turntables may be located above, below, adjacent to and / or spaced from one or more tanks. The turntable may be located below a fresh tank, adjacent to a fresh tank, or both.

One or more turntables may be located at least partially in a position within one or more reservoirs. One or more turntables may be in fluid communication with one or more reservoirs. One or more turntables may be located in a position within one or more turntable chambers. One or more components of the device may have one or more portions in which a turntable chamber is formed. The chamber may be reciprocal with the overall profile of the turntable. The chamber may allow the turntable to be located therein, attached therein while still allowing rotation, or both. One or more turntables may be located around, within and / or adjacent to a channel, a portion of a tank, a cap assembly, a valve assembly, an actuator assembly, a reservoir, the like, or a combination thereof.

[0055] The turntable can define a void. The void can be defined by an inner peripheral wall (e.g., an inner surface). The void can be defined by a track. The void can be defined by a hub. The hub can be a hub that is driven centrally or eccentrically. The track and / or the hub can have an engagement feature. The hub can be engaged with the drive unit indirectly or indirectly. For example, the hub can be a splined hub that cooperates with the drive unit (e.g., with a drive shaft or the like). A channel, a filling extension, a cap assembly, a valve assembly, an actuator assembly, a drive gear, a reservoir, or a combination thereof can be located at a position within the void. The void can be concentric and / or eccentric with the axis of rotation of the turntable.

[0056] The turntable can be located at a position within the device at an angle. The angle can be vertical, parallel, or any angle in between. The turntable can be located at a position at an angle defined by the track, track plane, hub, and / or center axis. The angle can be tilted in a manner between parallel and vertical. Tilt placement can allow for space saving within the device. Space can be saved by having one or more components located within the gap, still allowing enough angle for gravity to help the liquid flow out of the bucket, or both.

[0057] The turntable can rotate in one or more directions. One or more directions may include a first direction, a second direction, or both. One or more directions may be associated with one or more modes of the turntable. One or more modes may include filling, circulation, and / or emptying. When rotating in the first direction, the turntable may serve to fill the reservoir with fresh liquid (e.g., from a fresh tank), recirculate the liquid from the reservoir to the serving bowl, or both. The first direction may be referred to as the filling and / or recirculation direction. When rotating in the second direction, the turntable may serve to dispose of the used liquid from the reservoir to the used tank. The second direction may be referred to as the emptying direction. The first direction, the second direction, or both may be clockwise, counterclockwise, or both. The direction may be the direction when looking down at the device from a top view. For example, the first direction may be counterclockwise, and the second direction may be clockwise. In order to rotate in one or more directions, the turntable may be driven by receiving torque. Torque may be received from one or more gears (e.g., a drive gear). The one or more gears may be part of a drive unit. Torque may be received by any part of the turntable configured to engage with the drive unit. The torque can be received by the track of the turntable.

[0058] The turntable may include or not include a track. The track may serve to receive torque, rotate the turntable around an axis of rotation, cooperate with a drive unit, or a combination thereof. The track may have any suitable configuration for cooperating with and being driven by a drive unit. The track may include or be a gear, a toothed gear, or both. The gear may be a spur gear, a helical gear, an internal gear, or the like, or a combination thereof. For example, the track may be a spur gear with teeth that are evenly spaced and protrude around the periphery. The track may cooperate and / or engage with one or more gears. The one or more gears may be one or more gears of a drive unit. The track may engage with one or more drive gears. For example, the track may engage with a drive gear. The track may engage with the drive gear at or near the top, front, side, rear, bottom, or any combination thereof. The track may be located at a position around at least a portion or all of the outer periphery, inner periphery, or both of the turntable. The track may at least partially or completely surround the periphery (e.g., circumference) of the outer wall, inner wall, or both of the turntable. The track may surround and / or even define the gap of the turntable. The track can be located at a position at one or more edges (e.g., upper, outer, inner) of the peripheral wall of the turntable, being forced toward one or more edges (e.g., upper, outer, inner) of the peripheral wall of the turntable, and / or near one or more edges (e.g., upper, outer, inner) of the peripheral wall of the turntable. The track can be located at a position at the upper surface, the lower surface, partially and / or completely extending between the upper surface and the lower surface, or any combination thereof. The track can be roughly centered between the upper and lower surfaces of the turntable. The track can be forced close to the upper surface and / or the lower surface. The track can be substantially concentric, offset, or both relative to the center, large circle, small circle, or a combination thereof of the turntable. The track can be attached to and / or integrated into the body of the turntable. For example, the track can be integrated with the inner peripheral wall of the turntable. The track can be used to rotate the turntable around the axis of rotation during the filling mode, the circulation mode, and / or the emptying mode. The track can be used to rotate the turntable clockwise, counterclockwise, or both.

[0059] The track can be laid in a plane called the track plane and / or form a plane called the track plane. The track plane can form a certain angle relative to the vertical plane, the horizontal plane or a combination thereof. The track plane can be substantially orthogonal to the axis of rotation. The track plane can be at a certain angle relative to the vertical plane. The track plane can form an angle of about 0 degrees or more, about 10 degrees or more, about 20 degrees or more, about 30 degrees or more, about 40 degrees or more, or even about 45 degrees or more with the vertical plane. The track plane can form an angle of about 90 degrees or less, about 80 degrees or less, about 70 degrees or less, about 60 degrees or less, or even about 55 degrees or less with the vertical plane. For example, the track plane can form an angle of about 45 degrees to about 55 degrees with the vertical plane. The angle with the vertical plane can be an angle facing upward, an angle closest to the fresh tank, or both. The rotation of the track can cause the turntable to rotate around the axis of rotation. The rotation of the track can cause one or more barrels to rotate around the axis of rotation.

[0060] The turntable may include one or more barrels. One or more barrels may serve to collect and / or transfer one or more liquids. One or more barrels may cooperate with one or more spouts to dispose of one or more liquids. One or more barrels may cooperate with one or more openings to collect one or more liquids therein. One or more barrels may be formed as one or more depressions in the turntable. One or more barrels may open from the upper surface, the bottom surface, or both of the turntable. The barrel may or may not be conical. The barrel may have a cross-sectional shape that is substantially circular, oval, elliptical, square, rectangular, trapezoidal, triangular, rhombus, etc., or any combination thereof. For example, the barrel may have a cross-sectional shape that is oval, circular, and / or elliptical on one side (e.g., a curved wall) and more rectangular on the other side (e.g., a straighter wall). The cross section may be a cross section taken substantially perpendicular to the axis of rotation of the turntable, parallel to the plane of the track, or both. One or more barrels may include one or more circulation barrels, emptying barrels, or both. One or more circulation barrels may serve to recirculate the liquid in the device. One or more circulation barrels may serve to collect liquid from a reservoir and transfer it to a spout funnel or spout. One or more circulation barrels can play the role of transferring liquid from the reservoir to the serving bowl. One or more circulation barrels can play the role of transferring liquid that has passed through the filter. One or more emptying barrels can play the role of disposing liquid into the used can. One or more emptying barrels can play the role of collecting liquid from the reservoir and transferring it to the channel. One or more emptying barrels can play the role of transferring liquid from the reservoir to the used can. One or more circulation barrels can be adjacent to and / or spaced apart from one or more other circulation barrels, emptying barrels, or both. The one or more circulation barrels and emptying barrels can be configured in an alternating manner, a repeating pattern, and / or a similar manner. For example, the circulation barrel can be adjacent to the emptying barrel and repeat this pattern around the turntable. The alternating pattern can allow a substantially constant flow of circulating liquid and / or used liquid to be collected by the barrel and / or distributed via a spout. As another example, the circulation barrel can be adjacent to the circulation barrel that may be adjacent to the emptying barrel and repeat the pattern around the turntable. Having more circulation barrels can allow faster circulation and distribution of circulating liquid. As another example, the circulation barrel may be adjacent to the emptying barrel that may then be adjacent to another emptying barrel, and the pattern is repeated around the turntable. Having more emptying barrels can allow the used liquid to be emptied faster before filling the cleaning liquid. The circulation barrel may be adjacent to the emptying barrel. The circulation barrel and the emptying barrel may have a partition wall located in a position between the two. The one or more barrels may include a plurality of barrels. A plurality of barrels may be configured in a circular (e.g., radial) manner in the turntable. A plurality of barrels may include 2 or more barrels, 4 or more barrels, 6 or more barrels, or even 8 or more barrels. A plurality of barrels may include 30 or less barrels, 20 or less barrels, 18 or less barrels, 16 or less barrels, or even 14 or less barrels.As an example, the plurality of buckets may include 10 to 16 buckets.

[0061] One or more barrels may include one or more openings (e.g., barrel openings). The one or more openings may allow liquid to flow into the one or more barrels. The one or more openings may be located at the leading edge and / or corner of the barrel. The leading edge and / or corner may be the edge and / or corner of the barrel that is first contacted when the turntable rotates. The one or more openings may be formed adjacent to the partition wall of the barrel. The one or more openings may be mirrored with one or more other openings about the partition wall. The one or more barrels may be adjacent to the outer periphery (e.g., peripheral wall, outer surface) of the turntable and / or be forced toward the outer periphery (e.g., peripheral wall, outer surface) of the turntable. The one or more openings may be formed on the bottom surface, the upper surface, or both of the turntable. The one or more openings may be formed on the bottom surface. The bottom surface may be in contact with and / or immersed in the liquid. The bottom surface may be partially immersed in the liquid in the reservoir when rotating through the reservoir.

[0062] One or more circulation barrels can rotate into and / or through the reservoir. If liquid is in the reservoir, the liquid can enter the circulation barrel through the barrel opening. The liquid can pass through the barrel opening and enter the circulation barrel. When the turntable rotates in a first direction, the liquid can flow into the circulation barrel through the opening. When the turntable continues to rotate (e.g., in the first direction), the liquid can flow from the circulation barrel to the circulation spout.

[0063] One or more emptying barrels can be rotated into the reservoir and / or rotated through the reservoir. If the liquid is in the reservoir, the liquid can enter the emptying barrel through the barrel opening. The liquid can enter the emptying barrel through the barrel opening. When the turntable rotates in the second direction, the liquid can flow into the emptying barrel through the barrel opening. The liquid can be directed to the spout via one or more guide walls. One or more guide walls in the spout can play a role in guiding the liquid away from the barrel opening, flowing to the spout, allowing a sufficient volume of liquid to accumulate, and then having enough volume to distribute via gravity (e.g., overcoming friction). One or more guide walls can extend from the middle area of ​​the barrel toward the end of the spout. One or more guide walls can be formed as ribs. The liquid received in one or more barrels via one or more barrel openings can be discharged from the barrel via one or more spouts.

[0064] The turntable may include one or more spouts (e.g., barrel spouts). The one or more barrel spouts may serve to expel liquid from the turntable, transfer liquid from the turntable to one or more other components of the device, or both. The one or more barrel spouts may serve to expel liquid toward another spout, toward a passage, toward a serving bowl, toward one or more cans, or any combination thereof. The one or more spouts may guide liquid away from the barrel and out of the barrel. The one or more spouts may be at the inner periphery, outer periphery, within a boundary, or a combination thereof of the turntable. The one or more spouts may be forced at the inner periphery of the turntable and / or located at the inner periphery of the turntable. The one or more barrel spouts may be located approximately opposite to the one or more barrel openings. The one or more spouts may protrude away from the turntable, toward another portion of the turntable, or both. The one or more spouts may protrude away from the inner peripheral wall of the turntable, toward the center of the turntable, toward the bottom surface of the turntable, toward the upper surface of the turntable, toward the outer peripheral wall, toward the inner peripheral wall, or the like, or any combination thereof. When the barrel rotates to a position above the passage, the one or more spouts may protrude toward the passage. When the barrel is rotated to a position above the spout funnel or other spouts, one or more spouts may protrude toward the spout or spout funnel. One or more spouts may be located adjacent to and / or share a wall with the partition wall. The partition wall may form one of the surfaces of the spout. One or more spouts may include one or more circulation spouts, one or more used liquid spouts, or both. One or more circulation spouts may protrude from one or more circulation barrels, be in fluid communication with one or more circulation barrels, and / or be a part of one or more circulation barrels. One or more used liquid spouts may protrude from one or more emptying barrels, be in fluid communication with one or more emptying barrels, and / or be a part of one or more emptying barrels. One or more spouts may be rotated by a reservoir, on the spout funnel, on a channel, etc., or any combination thereof. One or more circulation spouts may rotate on the spout funnel. When rotated to a position above the spout funnel, any liquid in the barrel (e.g., circulation barrel) may flow into the spout funnel away from the pipe opening, through the barrel, and toward the circulation spout. This rotation may be the first direction of the turntable. When rotated to a position over the channel, any liquid in the bucket (e.g., an empty bucket) can flow from the bucket opening, through the bucket and into the channel toward the spent liquid spout. This rotation can be a second direction of the turntable.

[0065] The turntable may include one or more tabs. The one or more tabs may function to cooperate with one or more actuator assemblies. The one or more tabs may have any shape suitable for engaging and / or bypassing one or more parts of the actuator assembly. The one or more tabs may be configured as one or more protrusions from the surface of the turntable. The one or more tabs may protrude from the bottom surface, upper surface, inner periphery, outer periphery, or any combination thereof of the turntable. The one or more tabs may have a shape suitable for engaging and / or bypassing a yoke of the actuator assembly. The one or more tabs may have a shape suitable for engaging and / or bypassing one or more tangs of the actuator assembly. The one or more tabs may have one or more actuation surfaces, bypass ramps, or both. The one or more actuation surfaces may be one or more surfaces of the actuating actuator assembly. Actuation may mean contacting a portion of a yoke such as a tang, causing the yoke to rotate, or both. The one or more actuation surfaces may protrude at an angle so that the actuation surface may be substantially parallel and / or flush with the inwardly facing flat surface of the tang when in contact with the tang, facing the tang, or both. One or more bypass ramps can be one or more surfaces that bypass the actuator assembly. Bypass can mean avoiding engagement of the yoke, avoiding causing the yoke to rotate, or both. Bypass can mean remaining in contact with the actuator assembly or avoiding contact with the actuator assembly. One or more bypass ramps can be inclined (e.g., ramped). The inclined surface can allow the bypass ramp to contact a portion of the actuator assembly and prevent any subsequent movement when in contact. The tabs can cooperate with one or more force-applying devices to allow subsequent movement to be prevented. One or more tabs can include one or more open tabs, closed tabs, or both. One or more open tabs can cooperate with the actuator assembly to open the valve assembly. One or more closed tabs can cooperate with the actuator assembly to close the valve assembly. The turntable can include one open tab and one closed tab, multiple open tabs and one closed tab, one open tab and multiple closed tabs, or even multiple open tabs and multiple closed tabs. Multiple open and / or closed tabs can be spaced evenly and / or unevenly around the turntable.

[0066] The device may include one or more actuator assemblies. The actuator assembly may prevent and / or allow liquid to flow from one or more tanks into the reservoir. The actuator assembly may cooperate with the turntable or may not cooperate with the turntable to open and / or close the valve assembly. The actuator assembly may raise or lower one or more components, rotate one or more components, or both. The actuator assembly may directly or indirectly cause the valve assembly to be raised or lowered. By raising the valve assembly, the actuator assembly can release the seal of the fresh tank. By lowering the valve assembly, the actuator assembly can seal the fresh tank. The actuator assembly may be located near one or more turntables and / or adjacent to one or more turntables.

[0124] Modes of operation of the liquid dispensing device

[0125] A liquid dispensing device according to the present teachings may be capable of operating in one or more modes. The device may be particularly useful for being able to operate in multiple modes to allow refilling of serving bowls with fresh liquid, allowing circulation of liquid already in serving bowls, and / or providing drainage of liquid already consumed by animals. The device may have a filling mode, a circulation mode, an emptying mode, or a combination thereof. One or more modes may operate simultaneously. For example, the filling mode and the circulation mode may operate simultaneously or be combined into one. As another example, the circulation mode and the emptying mode may operate simultaneously or be combined into one. As yet another example, the filling mode and the emptying mode may operate simultaneously or be combined into one. One or more modes may be determined by the operating direction of the drive unit, the direction of rotation of the turntable, the position of the actuator assembly, the position of the valve assembly, or any combination thereof.

[0126] The one or more modes may include a fill mode. The fill mode may function to transfer fresh liquid from a fresh tank to a reservoir, a turntable, a serving bowl, or any combination thereof.

[0127] The filling mode can be activated by one or more drive units. One or more sensing devices can cause one or more drive units to be activated. Torque can be transmitted to one or more gears. The drive shaft can transmit torque from the motor to one or more gears. One or more drive units can transmit torque to the turntable. One or more gears can engage with the turntable. For example, the drive gear can engage with the track of the turntable. Rotation of the drive gear in a first direction can transmit torque to the turntable. The turntable can rotate in the first direction. Rotation of the turntable can cause one or more actuator assemblies, valve assemblies, or both to be actuated into an open position.

[0128] Rotation of the rotating disk in a first direction can move the actuator assembly into an open position. As the rotating disk rotates, one or more tabs of the rotating disk can contact one or more tangs of the actuator assembly. The actuating surface of the open tab can contact the lower tang. The actuating surface can contact the flat surface, the inward surface, or both of the yoke. Upon contact, one or more tabs can transfer torque to the actuator assembly. The yoke can rotate to an open position upon receiving torque. The torque can be transferred to a rotatable mount, a disk, or both. The torque can be transferred from the yoke to the rotatable mount and then to the disk. The disk can cooperate with the valve assembly to convert rotary motion into linear motion. The rotation of the disk can drive the pusher upward. The pusher rotating upward can cause the valve assembly to open.

[0129] The valve assembly moved into the open position can cause liquid to be dispensed from one or more tanks (i.e., the fresh tank). The valve assembly may include a sealing extension. The sealing extension may receive an axial force from a pusher of the actuator assembly. The axial force may be in a direction that causes the seal to disengage from the opening of the tank. The axial force may be in a direction toward the tank. For example, the upward movement of the pusher causes the sealing extension to move upward. The sealing extension may transfer the axial force to the seal. The seal may then move away from the opening of the fresh tank and create a gap. The liquid may flow through the opening from the gap. The liquid may then flow into the reservoir. The liquid may be referred to as fresh liquid (e.g., liquid dispensed from the fresh tank into the reservoir).

[0130] As liquid flows into the reservoir, the liquid can then flow through the discharge channel, flow to the serving bowl, or both. Liquid can flow from the fresh tank until the liquid in the reservoir reaches a certain liquid level. The certain liquid level can be when the liquid is at or near the height of the seal, the opening of the fresh tank, or both. The valve assembly can remain in the open position when the turntable rotates, the turntable stops rotating (i.e., the static position), or both. This can allow fresh liquid to flow from the fresh tank with the help of gravity as the liquid is consumed, evaporated, or both, without rotating the turntable, further actuating the actuator assembly, or both.

[0131] In addition to gravity filling or separately from gravity filling, fresh liquid can be collected by the turntable as the turntable continues to rotate in the first direction. As the turntable rotates, one or more barrel openings can pass through fresh liquid. The one or more barrel openings can pass through fresh liquid contained in the reservoir. When the barrel opening passes through fresh liquid, fresh liquid can enter a corresponding barrel (e.g., a circulation barrel) through the one or more barrel openings. As the turntable continues to rotate, fresh liquid can stay in the barrel until the turntable reaches the spout funnel. When the turntable rotates so that the barrel containing fresh liquid is located above the spout funnel, the fresh liquid can move toward the spout of the barrel. The spout can be a circulation spout. Then, fresh liquid can be distributed from the circulation spout into the spout funnel. Fresh liquid can be transferred from the spout funnel to the spout and then distributed into the serving bowl.

[0132] The flow of fresh liquid to the serving bowl may be stopped when the liquid is flush with the valve assembly, the turntable stops rotating, or both.

[0133] The one or more modes may include a circulation mode. The circulation mode may function to circulate liquid already in the reservoir and / or serving bowl, pass liquid through a filter, provide moving liquid to attract animals to the device, or any combination thereof.

[0134] The cyclic mode can be activated by one or more drive units. One or more sensing devices can cause one or more drive units to be activated. Torque can be transmitted to one or more gears. A drive shaft can transmit torque from a motor to one or more gears. One or more drive units can transmit torque to a turntable. One or more gears can engage with the turntable. For example, a drive gear can engage with a track of the turntable. Rotation of the drive gear in a first direction, a second direction, or both can transmit torque to the turntable. The turntable can rotate in a first direction, a second direction, or both.

[0135] When the turntable rotates in the first direction or the second direction, the used liquid can be collected by the turntable. The used liquid can also be a filtered liquid. The used liquid can be a liquid that was once in the serving bowl, passed through one or more filters and then flowed into the reservoir. When the turntable rotates, one or more barrel openings can pass through the used liquid. The one or more barrel openings can pass through the used liquid contained in the reservoir. When the barrel opening passes through the used liquid, the used liquid can enter the corresponding barrel (e.g., a circulation barrel) through the one or more barrel openings. When the turntable continues to rotate, the used liquid can stay in the barrel until the turntable reaches the spout funnel. When the turntable rotates so that the barrel containing the used liquid is located above the spout funnel, the used liquid can move toward the spout of the barrel. The spout can be a circulation spout. Then, the used liquid can be distributed from the circulation spout to the spout funnel. The used liquid can be transferred from the spout funnel to the spout and then distributed to the serving bowl.

[0136] The recirculation mode may be done simultaneously with the filling mode. For example, fresh liquid may be dispensed into a reservoir that also has used liquid therein. The recirculation mode may be done separately from the filling mode. The recirculation mode may be performed when the fresh tank is emptied but liquid is still present in the device's serving bowl, reservoir, or both.

[0137] The one or more modes may include an emptying mode. The emptying mode may function to transfer liquid from a serving bowl, a reservoir, a turntable, or a combination thereof to a used can. The emptying mode may function to dispose of liquid that has been consumed at least once.

[0138] The emptying mode may be initiated by one or more drive units. Torque may be transmitted to one or more gears. The drive shaft may transmit torque from the motor to the one or more gears. The one or more drive units may transmit torque to the turntable. The one or more gears may engage with the turntable. For example, the drive gear may engage with a track of the turntable. Rotation of the drive gear in a second direction may transmit torque to the turntable. The turntable may rotate in the second direction.

[0139] When the turntable rotates in the second direction, the turntable can pass through the used liquid in the reservoir. The used liquid can be a liquid that has been consumed by an animal, has been circulated previously, or both. The used liquid can be collected by the turntable for distribution to the used tank. When the turntable rotates, one or more barrel openings can pass through the used liquid. The one or more barrel openings can pass through the used liquid contained in the reservoir. When the barrel opening passes through the used liquid, the used liquid can enter the corresponding barrel (e.g., emptying the barrel) through the one or more barrel openings. When the turntable continues to rotate, the used liquid can stay in the barrel until the turntable reaches the channel. When the turntable rotates so that the barrel containing the used liquid is located in a position above the channel, the used liquid can move toward the spout of the barrel. The spout can be a used liquid spout. Then, the used liquid can be distributed into the channel from the used liquid spout. The used liquid can be transferred from the channel to the channel outlet. Then, the used liquid can be distributed to the used liquid tank from the channel outlet.

[0140] Rotation of the rotating disk in the second direction can move the actuator assembly into the closed position. When the rotating disk rotates, one or more tabs of the rotating disk can contact one or more tangs of the actuator assembly. The actuating surface of the closing tab can contact the upper tang. The actuating surface can contact the flat surface, the inward surface, or both of the yoke. When in contact, one or more tabs can transfer torque to the actuator assembly. The yoke can rotate to the closed position when receiving the torque. The torque can be transferred to the rotatable mount, the disk, or both. The torque can be transferred from the yoke to the rotatable mount and then to the disk. The disk can cooperate with the valve assembly to convert the rotary motion into linear motion. The rotation of the disk can drive the pusher downward. The downward rotation of the pusher may cause the valve assembly to close.

[0141] The valve assembly moved into the closed position can cause liquid to no longer be dispensed from one or more tanks (i.e., the fresh tank). The valve assembly can include a sealing extension. The sealing extension can receive an axial force from a pusher of the actuator assembly. The axial force can be in a direction that causes the seal to be located within the opening of the fresh tank. The axial force can be in a direction away from the fresh tank. For example, downward movement of the pusher causes the sealing extension to move downward. The sealing extension can transfer the axial force to the seal. The seal can then move toward the opening of the fresh tank and seal the gap. Liquid can stop flowing from the gap through the opening.

[0142] The turntable may rotate in the second direction and then in the first direction. This may cause the device to first enter an emptying mode to empty the used liquid into the used tank and then move to a filling and / or recirculation mode to refill the reservoir and / or serving bowl with fresh liquid, recirculate the liquid, or both.

[0143] The rotation may stop after a period of rotation in the first direction. This may cause the device to remain in a filling mode, stop a recirculation mode, or both. This may allow fresh liquid to continue to be dispensed from a fresh tank as liquid is consumed, evaporated, etc.

[0144] The turntable may rotate in the second direction, in the first direction, and then rotate back in the second direction. This may cause the device to first enter an emptying mode to empty the used liquid into the used tank, then move to a filling and / or recirculating mode to refill the reservoir and / or serving bowl with fresh liquid and / or recycled liquid, and then seal the fresh tank with the valve assembly in the closed position.

[0145] Fill, cycle, and drain algorithms

[0146] The devices and methods of the present teachings may rely on one or more algorithms to start and / or stop one or more operating modes, understand the animal's consumption trends, or both. The one or more algorithms may be stored in one or more memory storage devices, executed by one or more processing devices, or both. The one or more computing devices, memory storage devices, processing devices, or a combination thereof may be located within the device and / or remote from the device. The one or more algorithms may rely on input from one or more sensing devices, historical operation of the device, or both. The one or more algorithms may determine the amount of liquid consumed. Consumption may be determined based on determining the amount of liquid consumed, lost, evaporated, emptied, filled, etc., or any combination thereof.

[0147] Evaporation may be determined based on one or more environmental sensors and / or environmental inputs (e.g., a smartphone weather app). Evaporation may be determined based on relative (ambient) humidity, ambient temperature, or both. Losses may be calculated by determining a change in water level over a period of time. The water level may be determined via one or more level sensors. Emptying may be calculated via one or more level sensors located within the used tank, an input measuring the used liquid in the used tank, or both. Consumption may be determined based on evaporation, losses, emptying, etc.

[0148] For example, in order to determine the amount of liquid that has evaporated relative to consumption, the device can be weighed to determine the baseline weight, the total weight, and the in-use weight. The weight can be determined automatically by one or more mass sensors and one or more processors. The baseline weight can be the weight of the device completely emptied of any liquid. The total weight can be the weight of the device when the fresh tank is completely filled with liquid and then in position on the device. The total weight can also mean that when the fresh tank is completely filled, the used tank is empty. Once the device is in use (i.e., with consumed liquid), the ambient temperature and relative humidity can be used to determine the evaporation rate. The ambient temperature and relative humidity can be determined by one or more sensing devices. Once the device is in use, the loss rate can also be determined. The loss rate can be determined by the change in the liquid level over time. By comparing the evaporation rate with the loss rate, the consumption rate and the consumption amount can then be determined. Compared with knowing only the loss amount and / or rate, knowing the consumption amount and / or rate can give the animal owner a deeper understanding of the animal's drinking trends, provide a more accurate prediction of when the device needs to be refilled, or both.

The handle 60 is hollow so as to form a channel. Within the handle 60 is a translation rod 301. When the release button 67 (not shown) on the handle 60 is pressed, the translation rod 301 is driven downward. As the translation rod 301 translates downward, the translation rod 301 causes the rotation of the valve link 302. The valve link 302 rotates about the link pin 303. The rotation of the valve link 302 causes the stop valve 304 to move upward. The upward movement of the stop valve 304 causes the discharge opening 84 (not shown) to open so that liquid can be discharged through the discharge opening 84. Once the release button 67 (not shown) is released, the spring 305 may apply force to the valve link 302 to cause the stop valve 304 to move downward. The application of force also causes the valve link 302 to translate the translation rod 301 upward.

[0175] Assignment Examples

[0176] Example A: Actuator assembly and turntable

[0177] refer to Figures 24 to 35 Exemplary teaching.

[0178] The actuation surface 127 of the opening tab 109a is configured to contact the flat side of the flat side of the lower tang 210. When the turntable 100 rotates in the first direction D1, the contact occurs. The contact between the contact surface 127 of the opening tab 109a and the lower tang 210 actuates the actuator assembly 200. The contact between the contact surface 127 of the opening tab 109a and the lower tang 210 transfers torque from the turntable 100 to the yoke 202. Upon receiving the torque, the yoke 202 rotates in the same direction as the turntable 100. The rotation of the yoke 202 causes the same rotation of the rotatable mount 204. The rotation from the rotatable mount 204 causes the torque to be transferred to the disk 214 and rotate it. The rotation of the disk 214 also causes the rotation of the ramp surface 216. The ramp surface 216 rotates to a position that causes the pusher 218 to be raised. When the pusher 218 is raised, the valve assembly 56 opens. When the valve assembly 56 is opened, liquid is dispensed from the fresh tank 50 into the reservoir 24 .

[0179] The bypass ramp 128 of the closing tab 109b is configured to contact the rounded side of the upper tang 208 when rotated in the first direction D1. The contact between the bypass ramp 128 and the rounded side of the upper tang 208 causes the yoke 202 to pivot about the pin 206. The yoke 202 rotates, causing the tangs 208 and 210 to rotate upward, and the yoke 202 compresses the spring 220. The rotation of the upper tang 208 allows the opening tab 109a to bypass the yoke 202. After the closing tang 109b bypasses the yoke 202, the spring 220 forces the yoke 202 to return to a rest position.

[0180] The actuation surface 127 of the closing tab 109b is configured to contact the flat side of the upper tang 208. The contact occurs when the turntable 100 rotates in the opposite direction. The opposite direction is the second direction D2 and is opposite to the first direction D1. The contact between the contact surface 127 of the closing tab 109b and the upper tang 208 actuates the actuator assembly 200. The contact between the contact surface 127 of the closing tab 109b and the upper tang 208 transfers torque from the turntable 100 to the yoke 202. Upon receiving the torque from the turntable, the yoke 202 rotates in the same direction. The rotation of the yoke 202 by the closing tab 109b is in the opposite direction to that by the opening tab 109a. The rotation of the yoke 202 causes the same rotation of the rotatable mount 204. The rotation from the rotatable mount 204 is transferred to the disk 214 and causes it to rotate. The rotation of the disk 214 also causes the ramped surface 216 and the non-ramp surface 217 to rotate. The ramped surface 216 and the non-ramp surface 217 rotate to a position that lowers the pusher 218. When the pusher 218 is lowered, the valve assembly 56 is closed. When the valve assembly 56 (not shown) is closed, liquid from the fresh tank 50 is prevented from being dispensed, and the liquid from the fresh tank 50 is sealed in the fresh tank by the valve assembly 56.

[0181] The bypass ramp 128 of the opening tab 109a is configured to contact the rounded side of the lower tang 210 when rotated in the second direction D2. The contact between the bypass ramp 128 and the rounded side of the lower tang 210 causes the yoke 202 to pivot about the pin 206. The yoke 202 rotates, causing the tangs 208 and 210 to rotate upward, and the yoke 202 compresses the spring 220. The rotation of the lower tang 210 allows the opening tab 109a to bypass the yoke 202. After the opening tab 109a bypasses the yoke 202, the spring 220 applies force to the yoke 202 to return to the rest position.

[0182] Example B: Actuator Assembly

[0183] refer to Fig.14 and Figures 23 to Fig.35 Exemplary teaching.

[0184] Figure 23 to Fig. 27The actuator assembly 200 and the valve assembly 56 are illustrated in an open position OP. In the open position, the rotatable mount 204 rotates in the open direction OP. The rotation of the rotatable mount is stopped by the stopper 226. The rotation of the rotatable mount 204 drives the disk 214. The rotation of the disk 214 moves the ramp surface 216 and the non-ramp surface 217. The ramp surface 217 rotates toward the extension 220. The non-ramp surface 217 rotates away from the extension 220. When the ramp surface 216 rotates toward the extension 220, the extension 220 rises to the highest part of the ramp surface 216. The rise of the extension 220 causes the pusher 218 to be pushed upward. The pusher 218 is pushed upward causing the actuator assembly 200 to be in the open position OP. The rise of the pusher 218 drives the valve assembly 56 to the open position OP.

[0185] To be moved to the closed position (not shown), the rotatable mount 204 is rotated in the closing direction CD. The closing direction CD is opposite to the opening direction OD. The rotatable mount 204 is prevented from over-rotating by the stopper 226. The rotation of the rotatable mount 204 drives the disk 214. The rotation of the disk 214 moves the ramp surface 216 and the non-ramp surface 217. The ramp surface 216 rotates away from the extension 220. The non-ramp surface 217 rotates toward the extension 220. When the non-ramp surface 217 rotates toward the extension 220, the extension 220 is lowered to the non-ramp surface 217. This lowering causes the pusher 218 to lower and rest on the non-ramp surface 217 and the actuator assembly 200 is in the closed position. The lowering of the pusher 218 then drives the valve assembly 56 (not shown) to the closed position.

[0186] The rotation of the actuator assembly 200 is caused by the turntable 100. The turntable includes a tab 109 (such as Figure 32 to Figure 35 10). During rotation of the turntable 100, the contact surface 127 of the tab 109 contacts and pushes the corresponding tangs 208, 210 until the contact is broken and / or the rotatable mount 204 contacts one or more stops 226. The one or more stops 226 prevent further rotation of the rotatable mount 204. The torque acting on the tangs 208, 210 via the tab 109 causes the rotatable mount to rotate. The rotation of the rotatable mount 204 drives the disk 214.

[0187] When the actuator assembly 200 is rotated to the closed position, the pusher 218 moves to the lowered position. In the lowered position, the pusher 218 seats on the non-ramp surface 217 of the disk 214. The pusher 218 in the lowered position allows the valve assembly 56 to be fully seated within the fill opening 55 of the fill extension 54. To be fully seated, the seal 57 rests on the valve seat 125 and has an interference fit with the fill opening 55. By being fully seated in the fill opening 55, the valve assembly 56 seals the fresh tank 50 so that liquid is retained within the fresh tank 50 and is prevented from entering the reservoir 24.

[0188] When the actuator assembly 200 is rotated to the open position OP, the pusher 218 moves to the raised position. In the raised position, the pusher 218 sits on the ramp surface 216 of the disk 214. The pusher 218 in the raised position drives the valve assembly 56 through the fill opening 55 and further into the fresh tank 50. A gap is created between the seal 57 and the valve seat 125. The gap allows the liquid in the fresh tank 50 to drain into the reservoir 24.

[0189] Unless otherwise stated, any numerical value described herein includes all values ​​that increase progressively with one unit from the lower limit to the upper limit, provided that there is an interval of at least 2 units between any lower limit and any upper limit. For example, if the value of the amount, characteristic or process variable (such as temperature, pressure, time, etc.) of the expression component is, for example, 1 to 90, preferably 20 to 80, more preferably 30 to 70, then the mid-range value (for example, 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc.) is intended to be within the teaching of this specification.
