The present invention generally relates to a system and method for automatically dispensing living food to caged pets. More specifically, the present invention may be used to provide a convenient apparatus for habitation and dispensing of crickets to cricket-eating reptile.
By way of introduction, reptiles of all sizes are kept as pets. Common species of pet reptiles include turtles, frogs, snakes, and a wide array of lizards, such as bearded dragons, crested geckos, leopard geckos, iguanas, and chameleons. Ordinarily, the reptiles live their daily lives in an open or closed aquarium or terrarium, preferring a controlled habitat with water, food, and a heat source. Living food, most commonly crickets, is an integral part of the diet of most reptile species that are commonly kept as pets.
Live insect containers as well as conveying device have been developed. One example is U.S. Pat. No. 6,758,162 entitled “Reptile Feeder.” The '162 patent describes a method of feeding insects by providing a feeding apparatus consisting of a structure having a chamber in which the insects can move about, a cover that provides access to the chamber for introducing insects and powder supplements to the chamber, and a small port and manually removable port plug for enabling the insects to exit the chamber to the terrarium when the plug is removed.
An improved insect storage and dispensing device was disclosed in U.S. Pat. No. 6,877,269 entitled “Insect Container.” The '269 patent discloses an insect container that provides for holding, transporting, and singularly extracting individual crickets. The insect container includes hollow carrying tubes where insects reside until manually removed from the device to feed reptiles kept in separate terrarium.
U.S. Pat. No. 7,174,847 is entitled “Insect Habitat and Feeder.” This patent teaches an insect habitat and feeder, comprising of a tower compartment connected to a separate dusting compartment with apertures on both compartments that may be aligned by rotating the two compartments to form a passage for insects. The insects can move from the tower compartment to the dusting compartment which coats the insects with a nutritional dust. The insects are then allowed to move from dusting compartment through a feeder tube into a pet animal's habitat for consumption.
One or more of the embodiments of the present invention provide a system and a method for automatically dispensing living food to a caged pet. More specifically, the present invention may be used to provide a convenient apparatus for habitation and dispensing of living food, such as crickets, to a caged pet, such as cricket-eating reptiles. The system includes a top lid with air holes for air circulation, a rotatable carousel with cavities and nutrient compartments for storage and sustenance of living food, a main compartment casing the rotatable carousel having a food release hole, a base unit for seating the main compartment, a rotary mechanism to turn the rotatable carousel relative to the base unit, and a control unit to control the function of a timer that transmits signals indicating food release times. At food release times, the control unit is configured to deliver signals indicating execution to release living food to the motor to actuate a dispensing mechanism in response to timer settings preset by a user. Upon receiving a signal indicative of execution to release living food, the rotary mechanism rotates the rotatable carousel and consequently displaces stored living food in the main compartment circularly such that the living food may gravitationally drop through the food release hole to an external environment for the caged pet to consume. Alternative embodiments include additional features, such as a control panel comprising of a user interface for setting the timer according to a desired feeding schedule, a communication unit or connection to a communications network for remote control, a solar panel cells for additional power supply, and a video recording system for tracking pet activities.
The base unit 110 holds controls and mechanisms that allow for rotation of the rotatable carousel 150 and for performance of other functions of the automatic living food dispenser 100. The base unit 110 houses the battery compartment 111, the control unit 112, and the motor 115. The control unit 112 is electrically connected to the battery compartment 111 and the motor 115. The drive shaft 116 is mechanically attached to the motor 115. The base lid 120 is fitted over the base unit 110, enclosing the battery compartment 111, the control unit 112, and the motor 115. The switch 113 supported by the switch base 114 is affixed to the side of the base unit 110 and electrically connected to the control unit 112. The control unit 112 includes a microprocessor (not shown) that is preferably a single circuit card which is capable of controlling the various functions of the automatic living food dispenser. The control unit 112 also includes a timer (not shown) that controls time-sensitive functions and a memory (not shown) that stores various instructions input. The drive shaft 116 extends upwardly through a hole in the base lid 120 and a hole in the main compartment 140. The drive wheel 130 is mechanically linked to the drive shaft 116. The main compartment 140 is mounted on top of the base lid 120 and fixed by a turn and lock mechanism. The rotatable carousel 150 is placed inside the main compartment 140, such that a drive gear 158 facing the exterior on the bottom of the rotatable carousel as shown in
In operation, living food is placed inside the main compartment 150 housing the rotatable carousel 150 by lifting the top lid 160 off from the main compartment 140 or by removing the loading cover 161 to expose the loading hole 164 as shown in
In operation, a user sets the timer according to a desired feeding schedule using the switch 113. The desired feeding schedule is stored in the memory in the control unit 112. At a predetermined time, a release signal, an electrical communication signal representative of execution to release living food, from the timer is received at the microprocessor in the control unit 112. The microprocessor transmits the digital representation of the release signal to the motor 115. When the digital representation of the release signal is received by the motor 115, the motor 115 rotates the drive shaft 116 according to a designated speed. The drive shaft 116 is mechanically engaged with the drive wheel 130, which is mechanically engaged with the drive gear 158 that is affixed to the bottom of the rotatable carousel 150. In this way, the rotatable carousel 150 is rotated by the motor 115 and the drive shaft 116.
In one embodiment, programming of the automatic living food dispenser system 100 may operate through hardware, firmware, software, or some combination thereof.
In operation, the motor 115 rotates the rotatable carousel 150. When one of the cavities 151 of the rotatable carousel 150 holding living food aligns with the food release hole 144, living food in the cavity 151 may gravitationally drop to external environment and thus may become available to a pet to consume. The base unit 110 and the base lid 120 is cylindrically shaped with an inverted wedge mouth 118 that flares in a direction toward the circumference. The inverted wedge mouth 118 is greater in angular degree than one of the cavities 151 for the living food to be dropped from the cavity 151 freely.
In operation, living food is dropped into each cavity 151 by removing the loading cover 161 and exposing a loading hole 164 as shown in
Alternatively, the loading cover 161 may be made of a rubber that is biased in a closed position, but flexible enough to allow a user to open and insert or check the living food without having to completely move the top lid 160. In addition, one or more of the cavities 151 may be made of or have a darken surface. The darken surface has been shown to increase live food survivability by keeping the live food in a sense that it is night, decreasing their activity and metabolism.
In operation, living food compartmentalized by the rotatable carousel 150 is housed in the main compartment 140. The textured inner surface 153 maximizes surface area for habitation of the living food awaiting to be pushed out by a rotational force by providing more than one textured side for the living food to position itself without slipping or falling. The nutrient ledge 154 circularly outlines a nutrient compartment 155, as shown in
In operation, the control unit 112 is programmed, in part, to control power to the motor 115 that drives the drive shaft 116 affixed to the drive wheel 130. The drive wheel 130, fitted together with the drive gear 158 of the rotatable carousel 150, pivots, turning the rotatable carousel 150 housed in the main compartment 140. The control unit 112 may further control and monitor one or more position sensors (not shown) used to determine a position of the rotatable carousel 150 relative to the food release hole 144. The sensors may be optical sensors or photo-couplers.
Here, the dispensing mechanism is actuated according to a timer (not shown) set by the switch 113. In one embodiment, the switch 113 has four modes: an OFF mode, a 12 hour mode, a 24 hour mode, and a LOADING mode. The timer in the control unit 112 is programmed to read a position of the switch 113 and provide a release signal indicative of a food release time at the food release time when the switch 114 is set to the 12 hour or the 24 hour mode. The desired feeding schedule indicated by 12 hour or 24 hour mode is stored in the memory in the control unit 112. For example, if the switch 113 is set to the 12 hour mode, the desired feeding schedule of 12 hour frequency is stored in the memory in the control unit 112. The timer in the control unit 112 is further programmed to provide a release signal indicative of food release time in 12 hour intervals to the microprocessor in the control unit 112. Upon receiving the release signal, the microprocessor in control unit 112 transmits the release signal to the motor 115, which then runs and rotates the drive shaft 116 that is mechanically attached to the motor 115 in a release direction until a predetermined angular rotation has been reached. The predetermined angular rotation is equivalent to angular distance of one cavity 151, and is stored in the memory in the control unit 112. Thus, the motor 115 runs until next one of cavities 151 of the rotatable carousel 150 is aligned with the food release hole 144, as in
The control unit 112 is further programmed to read a position of the switch 113 and provide a loading signal indicative of a loading mode when the switch 113 is set to the loading mode. A loading angular rotation is continuously stored and updated in the memory in the control unit 112 when the switch 113 is set to the loading mode until the switch 113 is no longer set to the loading mode. Upon receiving the loading signal, the control unit 112 triggers the motor 115 to run and rotate the drive shaft 116 that is mechanically attached to the motor 115 in a loading direction, which is a direction opposite to release direction. For example, if the release direction is programmed to be clockwise, then the loading direction is counter-clockwise. The motor 115 runs in a direction opposite to release direction until the control unit 112 reads that the switch 113 is no longer set to the loading mode. When the switch 113 is no longer set to the loading mode, an offset angular distance is calculated from the predetermined angular rotation and the loading angular rotation stored in the memory in the control unit 112. The motor 115 runs until the offset angular distance is zero and, consequently, the next one of cavities 151 of the rotatable carousel 150 is aligned with the food release hole 144.
The control unit 112 may include other features such as a low battery light to direct the user to change the batteries.
Alternatively, the dispensing mechanism may be actuated according to a time set by the user or the manufacturer using a control panel, as further discussed in
It is preferable that the motor 115 is a step motor. The control unit 112 may be programmed to control the motor without a position sensor. For example, the control unit 112 may be programmed to initiate the motor 115 until a predetermined angular distance has been reached. Here, the angular distance is 45 degrees for an automatic living food dispenser with 8 cavities.
In operation, the rotatable carousel 150 is movable relative to the main compartment 140 that is fixed to the base lid 120 fitted over the base unit 110 in a direction to effect movement of the cavities 151 in a succession where the bottom opening of each cavities 151 registers with the food release hole 144 of the main compartment 140. The living food stored in the main compartment 140 and compartmentalized by the rotatable carousel 150 empties from the main compartment 140 through the food release hole 144 into the external environment. A user places a nutrient (not shown) for living food in each nutrient compartment 115 by opening the top lid 160 to access the main compartment 140. For example, a nutrient may be nutrient cube made of food, vitamins, and water formulated to be easily digested by crickets. The number of cubes placed inside the nutrient compartment will vary depending on how many cavities 151 are filled with crickets. The nutrient compartment 155 holds nutrient for living food, and the nutrient ledge 154 ensures that the nutrient stays inside the main compartment 140 when the corresponding cavity 151 registers with the food release hole 144 of the main compartment 140. The textured inner surface allows living food to utilize larger surface area while being stored in the main compartment 140, having more than one textured wall for the living food to position itself without slipping or falling
In the automatic living food dispenser 1600, the switch 1603 and the control panel 1604 are in electrical connection with the control unit 1605. The switch 1603 and the control panel 1604 are also in electrical connection with the user interface 1615, which is in electrical connection with the control unit 1605. The battery 1601 and the solar panel cells 1602 are in electrical connection with the control unit 1605. The video recording system 1616 is in electrical connection with the control unit 1605. The motion sensor 1617 is in electrical connection with the control unit 1605. The motor 1610, the drive shaft 1611, the drive wheel 1612, the drive gear 1613, and the rotatable carousel 1614 are in electrical connection with the control unit 1605. The telecommunications network 1618 is in wireless connection with the control unit 1605. The external device 1619 is in wireless connection with the telecommunications network 1618.
In operation, the battery 1601 and the solar panel cells 1602 provide power to the control unit 1605. A user sets a desired feeding time using the switch 1603 and the control panel 1604. The control panel 1604 allows the user to manually program the automatic living food dispenser according to the feeding schedule for the pet. The user interface 1615 may display a programmable LCD clock or list selections on an LCD display or touch screen. The input data indicative of the feeding schedule from the switch 1603, the control panel 1604, and the user interface 1615 is transmitted to the control unit 1605 and stored in the memory 1608. The input data indicative of the feeding schedule actuates the timer 1606. According to the feeding schedule, the timer 1606 sends a release signal indicative of a food release time at the food release time to the microprocessor 1607. The microprocessor 1607 transmits the release signal to the motor 1610, which then runs and rotates the drive shaft 1611. The drive shaft is mechanically attached to the drive wheel 1612, which is mechanically attached to the drive gear 1613 on the rotatable carousel 1614. Consequently, the motor 1610 turns the rotatable carousel 1614 concentrically. The wireless transceiver 1609 of the control unit 1605 transmits an output data indicative of a status of the automatic living food dispenser and the like to the telecommunications network 1618 through a wireless connection. The wireless transceiver 1609 also receives an input data, originating from the external device 1619, indicative of a desired execution for the automatic living food dispenser and the like from the telecommunications network 1618 through a wireless connection. The motion sensor 1617 transmits a motion data indicative of a position of the rotatable carousel 1614 to the control unit 1605. The video recording system 1616 transmits an input data representing a video file to the control unit 1605. The control unit 1605 stores the data representing the video file in the memory 1608.
The automatic living food dispenser 100 may be made of molded plastic or other suitable material. Using a translucent plastic allows living food placed inside the cavities 151 to be viewed from the outside.
Conventional insect feeding systems are typically manually operated. Conventional pet feeding systems are inappropriate for living food, such as crickets, that need its own air circulation and nutrients within a storage apparatus. These systems are inflexible to the needs of caged pet owners as they have a need to feed their pets, such as reptiles, on an automated basis. The need typically arises when the owner is absent and is unable to feed a pet at appropriate times.
As explained by Cunningham in U.S. Pat. No. 5,630,374, “Feeding crickets to one's pet reptile is an often messy and wasteful task. The crickets are generally packaged and brought from the store in plastic bags or cups. The pet owner will keep them in a lidded container, opening the container periodically to feed his pet. Each time, he must attempt to pour the correct number of crickets into the reptile's aquarium or other habitat as “excess” crickets are otherwise wasted due to their inability to seek food. Crickets often jump out of the container and escape into the house despite the owner's most careful efforts in doling out a meal. This forces customers to restrict their purchases to a two or three-day supply requiring frequent trips to the pet store.”
The present embodiment provides a device that minimizes the need for the pouring of crickets that provides an opportunity for their entropic escape because a plurality of crickets enough to nourish a pet for a longer duration can be loaded into the automatic living food dispenser at once using a loading hole or a top lid. The present embodiment also lessens the need to touch and handle the crickets once they are loaded into the device because the crickets are provided with air through an air hole and nutrients in a nutrient compartment to live inside the device and the device is set to automatically dispense crickets at a predetermined time and interval. In addition, the present embodiment provides the ability to control with consistency the number of crickets fed to the cricket-eating pet because a rotational carousel of the automatic living food dispenser compartmentalizes the crickets so that the dispensed living food is rationed and released at a predetermined feeding time at an interval.
While particular elements, embodiments, and applications of the present invention have been shown and described, it is understood that the invention is not limited thereto because modifications may be made by those skilled in the art, particularly in light of the foregoing teaching. It is therefore contemplated by the appended claims to cover such modifications and incorporate those features which come within the spirit and scope of the invention.
The present invention claims priority to U.S. Provisional Application Ser. No. 62/864,074 filed Jun. 20, 2019.
