Description

TECHNICAL AREA OF DISCLOSURE

[0001] The present disclosure relates generally to animal feeding apparatus and devices. In particular, the present disclosure relates to an automatic feeding device for feeding animals, especially in animal care. The device according to the invention allows settings to be made for automatic feeding at unpredictable, irregular times, thereby promoting species-appropriate feeding behavior while simultaneously ensuring safe and efficient feed dispensing. BACKGROUND

[0002] In managed animal care, common feeding practices involve the owner / keeper manually placing food during one or more scheduled feeding breaks. During the feeding break, an enclosure or open area is typically cleared of animals, allowing keepers to place food without risk of injury or disturbance. However, this method of feeding has several disadvantages, including the significant effort required for personnel, a degree of boredom in the animals due to the feeding routine, and the disruption of natural animal behaviors such as hunting, stalking, and patrolling.

[0003] As a result, food is now provided at predictable times and locations, which does not encourage the natural foraging instincts of animals, especially carnivorous ones. Such predictable feeding can lead to a reduction in physical activity, mental stimulation, and overall well-being. In the wild, carnivorous animals in particular exhibit complex behaviors related to hunting and foraging that are crucial to their physical and mental health. The lack of these physical activities in managed care settings can lead to problems such as obesity, stress, and other behavioral issues in the animals.

[0004] Existing approaches offer time-controlled pet feeders that do not adequately address the unique challenges of feeding large animals, especially carnivorous species. These include the need for flexible scheduling, the ability to safely dispense fresh meat, and the need to simulate the natural hunting behavior of carnivores.

[0005] Therefore, there is a need to address the above-mentioned technical drawbacks of existing technologies for an automatic feeder that not only feeds animals but also encourages their natural instincts in a controlled environment. SUMMARY

[0006] The present disclosure aims to provide a device for automatic animal feeding, in particular for predators. One objective of the present disclosure is to provide a technical solution that overcomes the problems encountered in the prior art and provides an improved automatic animal feeder for feeding animals at irregular, random times, thereby promoting species-appropriate feeding behavior of the animals, including hunting, stalking, and patrolling. The objective of the present disclosure is achieved by the solutions provided in the appended independent claims. Advantageous implementations of the present disclosure are further defined in the dependent claims.

[0007] In one aspect, the present disclosure provides an automatic feeding device for animals in animal care facilities such as, but not limited to, zoos and animal parks. The automatic feeding device includes a housing containing a feed chamber containing feed and a control chamber with a mechanical user interface and an electromechanical unit. The mechanical user interface includes one or more control elements configured to allow an animal keeper to set a feeding parameter for feeding feed at any time after a feeding pause.The electromechanical unit includes a control unit configured to receive an input signal from the mechanical user interface corresponding to the feeding parameter set by the animal keeper and to determine a feeding time based on the input signal to provide the feed at a specified feeding time. The specified feeding time is unpredictable for the animals and varies for each feeding event, thereby encouraging species-typical feeding behaviors, including hunting, stalking, and patrolling.

[0008] In some embodiments, the housing further comprises a feed door operatively coupled to the control unit. The feed door is configured to be operable between an open position and a closed position. The control unit is configured to operate the feed door from a closed position to an open position based on the determined random time to release the feed from the feed chamber to the animals.

[0009] In some embodiments, the one or more control elements comprise a control knob configured to be rotated to adjust at least one of a plurality of feeding parameters to program irregular feeding times after the feeding break, thus ensuring unpredictable feeding schedules for the animals. The feeding parameter corresponds to a feeding time.

[0010] Optionally, the control knob—in the version with a manual dial—is surrounded by a time indicator dial containing the multiple feeding parameters assigned to a specific time. An indicator arrow in the control knob points to at least one of the multiple feeding parameters when the control knob is rotated.

[0011] In another embodiment, the control unit optionally includes a digital display with a numeric display. In this embodiment with a digital display, a time countdown until the feed flap opens is displayed using variable numbers / parameters. The countdown reacts immediately to the actuation of the control button.

[0012] Optionally, the control unit includes a random time generator configured to determine a random time for feeding feed to the animals when the indicator arrow in the control knob does not point to any of the feeding parameters.

[0013] Optionally, the control element(s) comprises at least one buzzer, at least one first indicator, at least one second indicator, at least one third indicator, at least one down button, at least one up button, and directional arrows. The buzzer is configured to indicate when the animal keeper has completed an action corresponding to an operation of the automatic feeding device. The first indicator is configured to warn of an error condition related to the operation of the automatic feeding device. The second indicator is configured to indicate that the automatic feeding device is functioning correctly. The down button is configured to allow the feed door to be opened manually when the down button is pressed. The up button is configured to allow the feed door to be closed manually when the at least one up button is pressed.The directional arrows are configured to indicate the function of the buttons that control the feed flap.

[0014] In some embodiments, the feed chamber includes a linear actuator coupled to the feed door and configured to operate the feed door between a closed and an open position.

[0015] In some embodiments, the linear actuator is a pushrod mechanism. For example, the feed chamber may include a first pushrod mounting plate configured to mount the pushrod to the housing. The feed door may include a second pushrod mounting plate configured to mount the pushrod to the feed door.

[0016] Optionally, the electromechanical unit further comprises a housing configured to house the electronic hardware, wiring, and mechanical units, including the control unit, electrical cables, a power supply, a Universal Serial Bus (USB) port for receiving software updates, and a drive unit.

[0017] Optionally, the drive unit is connected to the push rod and configured to operate the push rod in response to a control signal from the control unit to move the feed gate between the closed and open positions. The control signal represents an operating state of the feed gate, including an open or closed state.

[0018] In some embodiments, the housing includes a dividing device configured to separate the feed chamber from the control chamber.

[0019] In some embodiments, the housing includes a maintenance cover located on top of the housing and configured to allow access to the control elements of the control chamber upon opening of the maintenance cover.

[0020] Optionally, the feed flap is attached to both sides of the housing. The feed flap can be attached to the housing using axles with cotter pins and washers.

[0021] In some embodiments, the housing includes a rear cover. The rear cover includes first holes for wall mounting the automatic feeding device, second holes for cable routing, and ventilation openings.

[0022] Each automatic feeding device includes a mechanical user interface, an electromechanical unit and a feed flap.

[0023] The automatic feeding devices of the present disclosure are advantageous because feed is delivered to the animals at irregular, random times in the animal care environments / facilities—outside of the actual, obvious feeding breaks for the animals—thus encouraging species-typical feeding behaviors such as chasing, stalking, and patrolling. Feeding at irregular times reduces feeding anticipation, which helps minimize anxiety and stress in the animals. The unpredictable feeding schedule improves cognitive engagement, promotes mental stimulation, and reduces boredom. Furthermore, placing the automatic feeding device in unpredictable locations also improves the animals' species-typical feeding behaviors.The automatic feeding device can be easily adjusted to set different feeding times, allowing it to be adapted to the specific needs of different animal species. The automatic feeding device is suitable for both indoor and outdoor environments.

[0026] The embodiments described herein, as well as the various features and advantageous details thereof, are explained in more detail with reference to the non-limiting embodiments illustrated in the accompanying drawings and detailed in the following description. Descriptions of known components and processing techniques have been omitted so as not to unnecessarily obscure the embodiments described herein. The examples used herein are provided merely to facilitate an understanding of the ways in which the embodiments described herein may be practiced and to enable those skilled in the art to practice the embodiments described herein. Accordingly, the examples should not be considered limiting the scope of the embodiments described herein.

[0027] As previously mentioned, there is still a need to address the aforementioned problems in animal feeding. The present disclosure offers a technical solution that overcomes the problems of the prior art and provides an automatic feeding device for feeding animals at irregular, random times, thereby encouraging species-appropriate behaviors such as hunting, stalking, and patrolling. Feeding at unpredictable intervals reduces food anticipation in animals, which helps minimize anxiety and stress in the animals. The variability of feeding times promotes mental engagement, improves cognitive stimulation, and reduces boredom. Furthermore, placing the automatic feeding device in unpredictable locations further supports natural behavior.The feeding time can be easily adjusted to create different feeding schedules, allowing it to be adapted to the specific needs of different animal species. The feeding device according to the invention is suitable for both indoor and outdoor use.

[0028] Fig. 1 shows an exemplary front view of an automatic feeding device 100 according to the present disclosure. The automatic feeding device 100 is designed to be positioned at one or more locations within animal care environments / facilities to automatically provide food at random times following a feeding pause. It should be noted that animal care environments / facilities encompass various environments where animals are kept and cared for, including domestic households, animal shelters, zoos, animal parks, rehabilitation centers, and wildlife sanctuaries, to name a few. Random time refers to intervals or moments that are unpredictable and do not follow a consistent or fixed schedule.In the context of the automatic feeding device 100, random times refer to the different periods during which food is delivered to the animals, ensuring that feeding events occur at irregular intervals. This unpredictability helps to simulate natural feeding conditions, thereby promoting species-typical behaviors and reducing the animals' ability to predict when they will be fed. The feeding break refers to a time window used by animal caregivers to deliver food to the animal enclosure and the optionally installed automatic feeders. During this time, the animals / predators are in their cages and not in the enclosure or open areas. This refers to the break during which the enclosure—free of animals—is restocked with food. Typically, after the feeding break, the animals easily find the food on the floor or in various containers.To prevent this effect of food discovery being too predictable and too easy, the automatic feeders located in the enclosure can be filled during feeding breaks. These will then only release the food after the delay interval set by the animal keeper has elapsed, or in a random manner.

[0029] The automatic feeding device 100 includes a housing 102 designed to house all elements of the automatic feeding device 100. In some embodiments, the housing 102 is comprised of multiple panels. The plurality of panels may include a front panel, a left side panel, a right side panel, a back panel, a bottom panel, and a top panel. All of the panels together form a durable, enclosed structure for the automatic feeding device 100, protecting all elements of the automatic feeding device 100 and ensuring reliable operation in both indoor and outdoor environments.It should be noted that the housing of the automatic feeding device 100 is typically constructed of durable and animal-safe materials designed to withstand regular use and environmental exposure, and is moisture-resistant, rust-proof, pest-resistant, and resistant to microorganisms. The housing 102 is divided into a feed chamber and a control chamber. The feed chamber is configured to store feed for animals. The control chamber includes a mechanical user interface and an electromechanical unit (in . Fig. 1 (not shown). The mechanical user interface is designed to allow an animal keeper to set a feeding parameter. The feeding parameter refers to specific settings and values ​​that determine how and when food should be delivered to the animals. The electromechanical unit includes a control unit configured to determine the feeding time after the feeding break based on the feeding parameter set by the animal keeper. The control unit determines the feeding time and enables a varied feeding experience that supports mental stimulation and reduces stress in the animals.

[0030] The housing 102 further includes a feed door 104 designed to close a feed opening through which feed is filled and dispensed and the feed chamber can be cleaned. In one case, the feed opening may be provided in the front panel of the housing 102, preferably at the lower end of the front panel. It should be noted that the feed opening may also be located in the middle or at the upper end of the front panel to accommodate different feeding mechanisms or accessibility needs. Furthermore, the feed opening may also be located in other panels of the housing 102. The feed door 104 is designed to be operable between an open position and a closed position. It should be noted that in the open position of the feed door 104, food is dispensed for feeding the animals.In the closed position of the feed flap 104, the food in the feed chamber is contained. The control unit is designed to move the feed flap 104 from the closed position to the open position at the specified feeding time.

[0031] The feed flap 104 is connected to the housing 102 via axles 105a, 105b with locking pins 109a, 109b, and washers 107a, 107b. The axles 105a, 105b allow the feed flap 104 to pivot between open and closed positions, while the washers 107a, 107b facilitate movement by reducing friction between the moving parts. The locking pins 109a, 109b are used to lock the axles 105a, 105b in place, preventing the axles 105a, 105b from slipping out of position during operation. In one case, a first axle 105a is used to mount the feed flap 104 to the left side panel of the housing 102. A first washer 107a and a first locking pin 109a are used to reduce friction and lock the first axle 105a in place.In another case, a second axle 105b is used to mount the feed flap 104 to the right side panel of the housing 102. A second washer 107b and a second locking pin 109b are used to reduce friction and lock the second axle 105b in place. Note that an alternative configuration allows the first axle 105a, the first washer 107a, and the first locking pin 109a to be used on the right side panel. Likewise, the alternative configuration allows the second axle 105b, the second washer 107b, and the second locking pin 109b to be used on the left side panel.

[0032] The housing 102 further includes a maintenance cover 108 covering an opening at the top of the housing 102. When the maintenance cover 108 is opened, the maintenance cover 108 provides access to one or more elements of the mechanical user interface, thereby enabling operation of the automatic feeding apparatus 100, such as filling with feed, dispensing food, and cleaning the automatic feeding apparatus 100.

[0033] Now we turn to the Fig. 2 and Fig. 3. The Fig. 2 and Fig. 3 show exemplary sectional views of the automatic feeding apparatus 100 from Fig. 1, in which the feed door 104 of the automatic feeding apparatus 100 is in the closed position 104a and the open position 104b according to the present disclosure. The housing 102 of the automatic feeding apparatus 100 is divided into the feed chamber 103a and the control chamber 103b using a partition / divider 116. The partition 116 not only provides structural support for the housing 102 but also minimizes the risk of contamination between the feed chamber 103a and the components of the control chamber 103b. Each unit, compartment, or chamber of the automatic feeding apparatus 100 can be accessed without disturbing the others, facilitating routine checks and maintenance of the feed chamber 103a and the control chamber 103b as needed. The feed chamber 103a is configured to receive and store food for animals.The control chamber includes the mechanical user interface 110 and the electromechanical unit 111.

[0034] The mechanical user interface 110 includes one or more controls. The controls are provided on a control panel. The mechanical user interface 110 is configured to allow the animal keeper to set the feeding parameters for automatically feeding food at random times after a feeding break. The controls include at least one control knob, at least one buzzer, one or more indicators, one or more buttons, and directional arrows. The control knob is configured to be rotated to set at least one of a plurality of feeding parameters to program irregular feeding times after the feeding break, thereby ensuring unpredictable feeding schedules for the animals. It should be noted that the feeding parameter is set randomly by the animal keeper.The control knob is configured to generate an input signal after the animal keeper sets the feeding parameter. The input signal corresponds to the feeding parameter set by the animal keeper. The feeding parameter corresponds to the feeding time. In some embodiments, the feeding parameter includes the duration of each feeding session, the frequency of feedings throughout the day, and the volume of feed to be dispensed per session. The control knob allows the animal keeper to manually adjust various feeding parameters by rotating the control knob to specific positions. As the control knob is rotated, it cycles through various detent positions or stops, each representing a different setting for parameters such as feeding times, duration, or feed quantity. The rotation can also be continuous, with a marked scale around the control knob indicating values ​​or intervals.Once the desired parameter is selected, the animal keeper can leave the control knob in that position, which saves the input. The control knob can also have a push function, where pressing the control knob confirms the selection or activates a specific mode. Such simple and intuitive operation allows for easy programming of irregular feeding schedules, ensuring different feeding times and amounts for the animals. It should be noted that instead of the control knob, sliders for precise adjustments, push buttons for selecting predefined feeding programs, or digital touch panels for fine-tuning the feeding settings can also be used. In addition to setting the feeding parameter, the mechanical user interface 110 also plays a crucial role in providing operational control and feedback to the animal keeper.The mechanical user interface 110 allows manual intervention to open or close the feed door 104, adjust other settings, and start or pause feeding cycles. One or more displays can indicate the status of the automatic feeder 100, such as error messages, operating status, and low feed levels. The buzzer can provide audible feedback when actions are completed or when the animal keeper's attention is required.

[0035] The electromechanical unit 111 includes a housing 112 configured to house one or more electronic hardware components, wires, and mechanical components. The housing 112 includes the control unit, electrical cables 122, a power supply 126, a USB port 124 for software updates, and a drive unit. The control unit is configured to receive the input signal from the control button and determine the feeding time based on the input signal for feeding the feed at the specified random time. In one embodiment, the control unit includes algorithms that utilize randomization techniques to ensure that feeding times vary and the animals do not develop a routine.In another embodiment, the control unit includes a random time generator configured to generate unpredictable feeding times, ensuring that the feeding schedule is not fixed and varies over time. It considers factors such as maximum and minimum feeding intervals to create randomness in the feeding schedule. In one example, the control unit may receive the input signal indicating that the animal keeper has set the feeding parameter, which includes a minimum interval of 2 hours and a maximum interval of 6 hours between feedings. Based on the input, the algorithms within the control unit would use the random time generator to calculate the next feeding time.Suppose the last feeding occurred at 10:00 AM; the random time generator could produce an output suggesting that the next feeding would occur at 12:45 PM, resulting in an interval of 2 hours and 45 minutes. The following feeding could then be scheduled for 4:15 PM, introducing a gap of 3 hours and 30 minutes. Such an approach not only ensures that feeding times remain varied and unpredictable, but also that the animals receive their food at intervals that mimic more natural foraging behavior, thereby reducing the likelihood that they will anticipate feeding times. It should also be noted that the random time generation varies for each feeding event, thus keeping the feeding time unpredictable for the animal. The feeding event refers to each instance in which food is dispensed to the animal.Each feeding event is characterized by its unique timing, feed quantity, and duration, all of which can be independently adjusted via the control unit. This variability ensures that no two feeding events are identical, helping to prevent animals from developing fixed feeding routines or expectations, thus promoting more natural foraging behavior and improving their overall well-being.

[0036] Furthermore, the electrical cables 122 in the electromechanical unit 111 connect the various components for efficient power and data transmission. For example, the control knob, buzzer, displays, buttons, and USB port 124 are connected to the control unit via the electrical cables 122. The power supply 126 ensures the unit's reliable operation by providing the required voltage and current via the electrical cables 122. Additionally, the USB port 124 is available to receive software updates, allowing the automatic feeding device 100 to be improved or debugged as needed. The drive unit, which is responsible for actuating the feeding mechanisms, is also housed in the housing.

[0037] The feed chamber 103a further comprises a push rod mechanism 118 that is operatively connected to the control unit. In particular, the push rod 118 is electrically connected to the drive unit on one side. The drive unit is connected to the control unit. On another side, the push rod 118 is connected to the feed door 104. After the random time for feeding has been determined, the control unit operates the drive unit at the set random time to actuate the push rod 118. The push rod 118 is configured to move the feed door 104 from the closed position 104a to the open position 104b to release the feed to the animals. As in the example in Fig. As can be seen, the feed flap 104 is in the closed position 104a when the feed is not released. In the closed position 104a, the animals have no access to the feed until the specified random time is reached. As in the example in Fig. As can be seen, the feed flap 104 is in the open position 104b when the feed is to be released at random times. In the open position, the animals have access to the feed in the feed chamber 103a. As shown in Fig. As shown, the chuck door 104 is secured to the housing 102 using the axles 105a, 105b, the cotter pins 109a, 109b, and the washers 107a, 107b. This allows the chuck door 104 to move smoothly with less friction between the closed position 104a and the open position 104b.

[0038] The chuck chamber 103a includes a first push rod mounting plate 120a configured to mount the push rod 118 to the housing 102. In one case, the first mounting plate 120a is secured to the partition wall 116. The push rod 118 is mounted to the first mounting plate 120a using a third axle 105c, a third washer, and a third cotter pin (not shown). The chuck door 104 includes a second push rod mounting plate 120b configured to mount the push rod 118 to the chuck door 104. The push rod 118 is mounted to the second mounting plate 120b also using the third axle 105c, a third washer, and a third cotter pin (not shown).

[0039] The housing 102 further includes drip edges 106 at the points where the feed flap 104 meets the housing 102 to manage and drain away any excess moisture or food residue that may occur during the feeding process. The drip edges 106 direct liquids away from the interface between the feed flap 104 and the housing 102 and prevent the accumulation of residues that could lead to corrosion or malfunction of the mechanical components. The drip edges 106 serve to drain and keep out, for example, rainwater, external moisture, saliva, cleaning agents, or other liquids that could soften, dilute, or otherwise damage the feed contained in the feeder when the flap is closed.

[0040] Regarding the Fig. 1-3 shows the Fig. 4 shows an exemplary rear view of the automatic feeding apparatus 100 according to the present disclosure. The rear view of the automatic feeding apparatus 100 shows the rear panel 102a. The rear panel 102a includes first holes 128 for wall mounting the automatic feeding apparatus 100 to ensure secure and stable installation in various areas of the animal care environment. The rear panel 102a further includes second holes 130 for cable routing, which allow for organized management of the electrical cables and connections, thus preventing tangling or damage. The rear panel 102a further includes ventilation openings 132 designed to promote airflow and heat dissipation and prevent overheating of the internal components during extended use.The ventilation openings 132 ensure that the electromechanical module 111 remains within safe operating temperatures, thereby extending the service life of the automatic feeding apparatus 100.

[0041] Regarding the Fig. 1-4 show the Fig. 5 and Fig. 6 illustrate exemplary views of the one or more control elements 110a-110h of the mechanical user interface 110 of the automatic feeding apparatus 100 according to the present disclosure. The one or more control elements 110a-110h include the control knob 110a, the one or more buttons 110b-110c, the one or more indicators 110d-110e, the directional arrows 110f-110g, and the buzzer 110h. The one or more control elements 110a-110h may be aligned on the control panel. The control knob 110a functions by allowing the animal caregiver to manually adjust various feeding parameters by rotating the control knob 110a to specific positions. As the control knob 110a is rotated, the control knob 110a cycles through various detents or stops, each of which represents a different setting for parameters such as feeding times, durations, or feed amounts.The rotation can also be continuous, with a marked scale around the control knob indicating the available values ​​or intervals. Once the desired parameter is selected, the zookeeper can leave the control knob 110a in that position, thereby saving the input. The control knob can also have a push function, where pressing the control knob 110a confirms the selection or activates a specific mode. As shown in . Fig. 6, the control knob 110a is surrounded by a time indicator dial that includes the plurality of feeding parameters according to time. An indicator arrow in the control knob 110a points to at least one feeding parameter from the plurality of feeding parameters by rotating the control knob 110a. In an exemplary embodiment, the time indicator dial includes a setting between 0-10 hours, where a setting between 0-1 indicates that the opening countdown is approximately 1 minute. Likewise, a setting between 1-10 indicates that the opening countdown is in hours. The tolerance may be + / - half an hour. In another exemplary embodiment, the control unit 136 determines that the feed flap 104 should be opened after 2 hours from a trigger point when the animal keeper rotates the control knob 110a to point to a setting of 2.In another exemplary embodiment, the predetermined time may be adjusted by rotating the control knob 110a before the specified feeding time has elapsed.

[0042] Optionally, the control unit 136 includes a random time generator 140 configured to determine a random time for feeding the animals when the indicator arrow in the control knob 110a is not pointing to any of the feeding parameters. In a case where the control knob 110a is set to the rightmost setting of 10.5 on the time indicator dial, the random generator is activated, ensuring that the release time after the starting point is completely unpredictable within a time window of 1 to a maximum of 3 hours.

[0043] The one or more buttons 110b-110c include a down button 110b and an up button 110c. The down button 110f is configured to enable manual opening of the feed door 104 upon pressing the down button 110f. The up button 110g is configured to enable manual closing of the feed door 104 upon pressing the up button 110g. The one or more indicators 110d-110e include a first indicator 110d and a second indicator 110e. The first indicator 110d is configured to indicate a fault condition associated with the operation of the automatic feeder 100. In one case, the first indicator 110d may be a red LED. The second indicator 110e is configured to indicate that the automatic feeder 100 is functioning correctly. In one case, the second indicator 110e may be a green LED.It should be noted that other visual indicators may also be used. The directional arrows 110f-110g include a down arrow 110f and an up arrow 110g. The down arrow 110f indicates the function of the down button 110b for controlling the feed flap. The up arrow 110g indicates the function of the up button 110g for controlling the feed flap. The buzzer 110h is configured to indicate when the animal keeper has completed an action associated with the operation of the automatic feeding device 100.

[0044] After removing the maintenance cover 108, the maintenance cover 108 provides access to the one or more controls 110a-110h of the mechanical user interface 110. As shown in Example in Fig. 5, the one or more control elements 110a-110h are visible and accessible after removal of the maintenance cover 108. Fig. 6 shows a top view of the one or more controls 110a-110h of the mechanical user interface 110. In some embodiments, the top plate of the housing 102 includes a hole covered by the service cover 108. Upon removal of the service cover 108, the one or more controls 110a-110h of the mechanical user interface 110 are accessible through the holes. The service cover 108 is attached to the housing 102 with a plurality of screws 134. It should be noted that the service cover 108 can also be secured to the housing 102 via other mechanisms, including quick-release fasteners, snap-in connections, a hinge mechanism, magnetic closures, and gasket seals. The service cover 108 is made of the same material as the panels of the housing 102, or a similar material.

[0045] The Fig. 7a-7d are exemplary perspective views of an automatic feeding apparatus 100 according to the present disclosure. To avoid repetition, the individual components of the automatic feeding apparatus 100 and their functions are not explained here, which are described in the Fig. are described. Fig. Figure 7a shows a perspective view of the automatic feeding apparatus 100 with the feed flap 104 completely closed. Fig. 7b-7c show a perspective view of the automatic feeding apparatus 100 with the feed flap 104 partially open after the feed flap 104 has been activated by the control unit 136. Fig. Figure 7d shows a perspective view of the automatic feeding apparatus 100 with the feed door 104 fully open and dispensing feed to the animal. In some embodiments, the automatic feeding apparatus 100 is Fig. described, operated according to the following instructions described here. In the initial state, the feed flap 104 is open and emptied. In step 1, the feed flap 104 is cleaned with warm water and a little dish soap, after which the feed flap 104 is dried with a dry towel. In step 2, the maintenance cover 108 is removed using a tool provided together with the automatic feeding device 100. The screws 134 are never loosened during normal operation; they only serve to fasten the permanently installed, outer maintenance hatch ring, which in turn contains a large thread into which the actual maintenance hatch cover is screwed in and out. The maintenance cover 108 therefore consists of two main components: i) the outer ring and ii) the large, round screw cover equipped with a screw thread and sealing ring.In step 3, the downward arrow 110f is used to move the feed door 104 to a desired position, after which the feed is filled into the feed chamber 103a of the automatic feeding device 100. In step 4, after filling, the control knob 110a is used to set a desired opening countdown between 1 and 10 hours. In step 5, the upward arrow 110g is used to raise and close the feed door 104. Note that one of the directional arrows 110f–110g must be pressed until the green LED 110d begins to illuminate. Only when the green LED illuminates does the countdown begin. In step 6, if the set period is to be changed, the time is readjusted on the control knob 110a. The selected countdown then changes immediately. In step 7, the maintenance cover 108 is put on and the numerous screws 134 are tightened clockwise using the tool provided.It is important to ensure that the maintenance cover 108 closes securely to prevent moisture from penetrating the housing 102. In step 8, the feed door 104 is opened after the selected countdown has elapsed, and feed is delivered to the animals. The ramp created when the feed door is opened allows the feed contained in the feed door to exit to the outside.

[0046] With reference to the Fig. shows the Fig. 8 is an exemplary block diagram of the electromechanical unit 111 of the automatic feeding apparatus 100 according to the present disclosure. The electromechanical unit 111 includes the control unit 136, the drive unit 138, the electrical cables, the power supply, and the Universal Serial Bus (USB) port for receiving software updates (not shown). Fig.shown). The control unit 136 is a central processing unit of the automatic feeding apparatus 100, responsible for managing all operations based on user inputs and programmed feeding parameters. The control unit 136 receives signals from the mechanical user interface 110, such as inputs from the control knob 110a to determine the feeding time or from the buttons 110b-110c to open or close the feed flap 104. In addition, the control unit 136 uses algorithms or the random time generator to ensure that the feeding schedule is varied, thereby preventing the animals from anticipating feeding times. In addition, the control unit 136 communicates with other components such as indicators, the buzzer 110h, and the drive unit 138 to ensure that all actions are coordinated and executed as intended.

[0047] The control unit 136 includes a microprocessor (not shown) that executes programmed instructions that control a feeding schedule, randomization of feeding times, and overall coordination of the system's components. The microprocessor processes input signals received from the control knob 110a and other user interface elements, interprets the settings, and generates output signals to control components such as the drive unit 138, the indicators 110d-110e, and the buzzer 110h. The microprocessor also executes the algorithms that determine the random feeding times to ensure the unpredictable feeding schedule and prevent the animals from forming fixed routines. In addition, the microprocessor in the control unit 136 manages the synchronization of all activities, such as:monitoring the status of the feed flap and providing real-time feedback to the livestock owner through indicators 110d-110e or alerts. The microprocessor may also include troubleshooting features that allow it to detect and respond to faults or irregularities, thereby improving the reliability of the automatic feeding apparatus 100. The microprocessor's software can be updated via the USB port 124 included in the automatic feeding apparatus 100 to add new functions or enhance existing ones, further enhancing the performance and adaptability of the automatic feeding apparatus 100.

[0048] The drive unit 138 is a motorized component responsible for initiating the physical movement of parts such as the push rod 118 and the feed flap 104. The drive unit 138 receives control signals from the control unit 136 and uses power to operate the mechanical components involved in dispensing feed to the animals. Upon receiving the control signal from the control unit 136 at the predetermined random feeding time, the drive unit 138 operates the push rod 118, which moves the feed flap 104 from the closed position 104a to the open position 104b, releasing feed into a feeding area. The operation of the drive unit is critical for ensuring smooth and precise control of the mechanical elements, guaranteeing reliable feeding at the desired intervals.The combination of the control unit 136 and the drive unit 138 enables automated and controlled feeding, which increases the comfort for the animal owner while maintaining a flexible feeding routine for the animals.

[0049] The automatic feeding apparatus 100 of the present disclosure prevents animals from establishing fixed routines by providing food at unpredictable times after the feeding break, thereby encouraging natural feeding behavior and reducing anxiety. The random time is unpredictable for the animals. The user-friendly mechanical interface 110 enables simple interaction and facilitates the input of feeding parameters as well as control over the operation of the feeder flap without requiring extensive technical knowledge. The automation of the feeding process minimizes the need for constant monitoring and manual intervention, which is particularly beneficial for caregivers caring for multiple animals.

[0050] Furthermore, placing the automatic feeding device 100 in unpredictable, different locations offers several advantages that enhance the overall feeding experience for animals and their caregivers. Such an approach allows for the stimulation of natural foraging behavior, as animals must search for their food, which promotes physical activity and mental engagement. Furthermore, the variety of locations helps prevent boredom and encourages exploration, contributing to improved mental health and well-being for the animals. For caregivers, the ability to position the feeding device 100 in different areas facilitates better management of feeding practices and allows them to adapt feeding arrangements based on specific animal needs, social dynamics, and spatial constraints within the care environment.Furthermore, this flexibility can help minimize competition for food between animals by distributing feeding opportunities across different zones, resulting in a more harmonious environment. The unpredictability of food placement also reduces the likelihood of animals developing fixed routines that can lead to behavioral problems such as anxiety or food guarding.
