Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and in particular to an automatic pet bowl storage and dispensing device and an automatic feeding device. Background Technology

[0002] In recent years, with the increasing number of pet owners, more and more pet owners are choosing to feed their pets fresh food rather than traditional dry food, out of concern for their pets' health. Fresh food is richer in nutrients and can better meet the nutritional needs of pets.

[0003] To improve the convenience of pet care and ensure regular feeding, many pet owners are starting to choose automatic feeders. Existing automatic feeders can provide food to pets at preset times and in preset amounts, greatly simplifying the daily lives of pet owners.

[0004] However, existing automatic pet feeders typically use reusable bowls made of metal or plastic. Because fresh pet food is inherently sticky and oily, it easily leaves residue on the bowl after the pet has eaten. This residue not only makes cleaning the bowl tedious and complicated, but also allows bacteria to grow, posing a potential threat to the pet's health and increasing the risk of illness. While disposable bowls avoid the problems of cleaning and bacterial growth, they still require manual replacement after each feeding, reducing convenience and contradicting the convenience intended by automatic feeders. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pet bowl storage and automatic feeding device to solve the technical problems in the prior art where reusable pet bowls are prone to bacterial growth leading to poor safety, while disposable pet bowls require manual replacement, resulting in poor convenience.

[0006] To achieve this objective, the present invention adopts the following technical solution: On one hand, the present invention provides an automatic pet food bowl storage device, which includes: The placement mechanism includes a bowl storage section and a bowl separation component; the bowl storage section is used to stack and accommodate multiple bowls, and the bottom of the bowl storage section forms a bowl outlet. The bowl separation component is disposed at the bowl outlet and is used to separate the multiple bowls stacked in the bowl storage section one by one and release them downwards to the placement station. A conveying mechanism is disposed below the placement mechanism. The conveying mechanism is used to receive the released bowl at the placement station and convey the bowl to the feeding station, and to convey the bowl located at the feeding station to the recycling station. The recycling mechanism includes a bowl collection container with a top-opening receiving cavity inside; the recycling station is located above the bowl collection container, and the bowl located at the recycling station can automatically fall into the receiving cavity.

[0007] Preferably, the bowl separation component includes a drive mechanism and a switching wheel. The drive mechanism is used to drive the switching wheel to rotate around its own axis. The side wall of the switching wheel is provided with a spiral guide surface that extends spirally from top to bottom. Among the stacked bowls, the edge of the bottommost bowl rests on the top of the spiral guide surface. When the switching wheel rotates, the bowl resting on the spiral guide surface slides down along the spiral guide surface and eventually detaches.

[0008] Preferably, there are multiple switching wheels, which are arranged at intervals around the outer periphery of the bowl opening, and the driving mechanism can synchronously drive the multiple switching wheels to rotate synchronously around their own axis.

[0009] Preferably, the drive mechanism includes a first drive motor, a drive gear, a driven gear, and a rotating shaft. A rotating shaft is provided at the center of each switching wheel, and the rotating shaft coincides with the axis of the switching wheel. The output end of the first drive motor is coaxially connected to the drive gear, and the drive gear meshes with the driven gear. The driven gear has a transmission groove extending circumferentially. Multiple rotating shafts pass through the transmission grooves, and shaft gears are sleeved on the outer periphery of the rotating shafts. The shaft gears mesh with the inner wall of the transmission grooves.

[0010] Preferably, the conveying mechanism includes a second drive motor and a transmission turntable. The transmission turntable has at least one bowl groove along its circumference for supporting the bowl. The output end of the second drive motor is coaxially disposed on the transmission turntable to drive the transmission turntable to rotate around its own axis, so that the bowl groove can switch between the placement station, the feeding station and the recycling station.

[0011] Preferably, the recycling mechanism further includes a switching component. Multiple collection containers are provided, and the switching component is connected to multiple collection containers. The switching component can drive multiple collection containers to move, so as to selectively move one of the collection containers to the recycling station.

[0012] Preferably, the switching component includes a third drive motor and a recycling turntable. The plurality of collection bowls are detachably connected to the recycling turntable. The output end of the third drive motor is coaxially connected to the recycling turntable. The third drive motor can drive the recycling turntable to rotate around its own axis, thereby moving the plurality of collection bowls along the rotation path of the recycling turntable, so that one of the collection bowls moves to the recycling station.

[0013] Preferably, the automatic pet bowl disposal device also includes a housing, in which the placement mechanism, the conveying mechanism, and the recycling mechanism are all housed.

[0014] Preferably, the housing has a feeding port that communicates with the feeding station, and the bowl located at the feeding station can be exposed to the outside through the feeding port; And / or, the housing has a placement opening that communicates with the storage bowl section, and the bowl can be placed in the storage bowl section through the placement opening.

[0015] On the other hand, the present invention also provides an automatic feeding device, which includes a food storage bin, a feeding control mechanism, and the aforementioned automatic pet bowl dispensing device. The food storage bin is used to store pet food. The feeding control mechanism is connected to the food storage bin, and the food outlet of the feeding control mechanism corresponds to the feeding station of the automatic pet bowl dispensing device. The feeding control mechanism is used to control the pet food to be discharged from the food storage bin and fall into the pet bowl located at the feeding station.

[0016] The beneficial effects of this invention are: The automatic pet food bowl placement and collection device proposed in this invention achieves fully automated processing of the entire process of food bowl supply, transfer, and post-use collection through the coordinated operation of a placement mechanism, a conveying mechanism, and a collection mechanism. Specifically, the bowl storage section of the placement mechanism can pre-stack multiple food bowls, and the bowl separation component separates the stacked bowls one by one at the bowl outlet and releases them downwards to the placement station. This avoids the cumbersome operation of manually changing the food bowls after each feeding, as required by existing technologies, and automates the food bowl supply process. The conveying mechanism located below the placement mechanism can receive the released food bowls at the placement station and transport them to the feeding station for the pet to eat. After the pet has finished eating, the conveying mechanism can transport the food bowls to the collection station. This conveying path design allows the food bowls to complete the flow from a ready-to-use state to a used state and then to a ready-to-be-collected state throughout the entire usage cycle without manual intervention, improving the overall operating efficiency and ease of use of the automatic feeding device. The recycling system uses a bowl collection container to form a top-opening cavity below the recycling station. When used bowls are transported to the recycling station, they automatically fall into the cavity for centralized storage. This not only prevents dirty bowls from accumulating in the feeding area but also facilitates subsequent centralized cleaning.

[0017] In summary, this automatic pet bowl dispensing and recycling device achieves automated feeding, use, and recycling of disposable pet bowls without any human intervention. It retains the hygiene advantages of using a new bowl each time and avoids the health risks to pets caused by bacteria growth from leftover food, while overcoming the drawback of frequent manual bowl replacement. Therefore, this device improves the automation level and user experience of the feeding process while ensuring feeding hygiene and safety. Attached Figure Description

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 See Figures 1 to 13 The automatic pet food bowl disposal device provided in this embodiment of the invention includes a placement mechanism 2, a conveying mechanism 3, and a recycling mechanism 4. The placement mechanism 2 includes a bowl storage section 21 and a bowl separation component 22. The bowl storage section 21 is used to stack and accommodate multiple food bowls 1, with a bowl outlet 211 formed at the bottom. The bowl separation component 22 is disposed at the bowl outlet 211 and is used to separate the multiple food bowls 1 stacked in the bowl storage section 21 one by one and release them downwards to the placement station a. The conveying mechanism 3 is disposed below the placement mechanism 2 and is used to receive the released food bowls 1 at the placement station a, convey the food bowls 1 to the feeding station b, and convey the food bowls 1 located at the feeding station b to the recycling station c. The recycling mechanism 4 includes a bowl collection container 41, with a receiving cavity formed inside the bowl collection container 41 and an open top. The recycling station c is located above the bowl collection container 41, and the food bowls 1 located at the recycling station c can automatically fall into the receiving cavity.

[0025] The automatic pet food bowl disposal device proposed in this invention achieves fully automated processing of the entire process of food bowl 1 supply, transfer, and post-use collection through the coordinated operation of the placement mechanism 2, the conveying mechanism 3, and the recycling mechanism 4. Specifically, the storage bowl section 21 of the placement mechanism 2 can pre-stack and accommodate multiple food bowls 1, and the bowl separation component 22 separates the stacked food bowls 1 one by one at the outlet 211 and releases them downwards to the placement station a, thus avoiding the cumbersome operation problem caused by manually changing the food bowls 1 after each feeding in the prior art, and realizing the automation of the food bowl 1 supply process. The conveying mechanism 3, located below the placement mechanism 2, can receive the released food bowls 1 at the placement station a and convey them to the feeding station b for the pet to eat. After eating, it can convey the food bowls 1 to the recycling station c. This conveying path design allows the food bowls 1 to complete the flow from the standby state to the use state and then to the recycling state without manual intervention throughout the entire use cycle, improving the overall operating efficiency and ease of use of the automatic feeding device. The recycling mechanism 4 forms a top-opening receiving cavity below the recycling station c through the bowl collection container 41. When the used bowl 1 is conveyed to the recycling station c, it can automatically fall into the receiving cavity for centralized storage, which not only avoids the accumulation of dirty bowls 1 in the feeding area, but also provides convenience for subsequent one-time centralized cleaning.

[0026] The working principle and specific structure of the automatic pet food bowl retractor are explained in detail below.

[0027] The food bowl 1 is used to hold pet food, and its shape, size, and material can be customized to meet various usage needs. For example, in terms of shape, the food bowl 1 can adopt common geometric contours such as round, oval, square, or polygonal, or it can be designed with biomimetic or irregular shapes. In terms of material, the food bowl 1 can be made of plastic, pulp, plant fiber, biodegradable polymer materials, or thin metal sheets to meet different cost, environmental protection, and strength requirements. In terms of structure, the food bowl 1 can be a shallow or deep bowl with a single cavity, or it can be a multi-compartment bowl with one or more dividers to accommodate the separate placement of different types of food. In addition, the edge of the food bowl 1 can be equipped with flared edges, flanges, or reinforcing ribs to facilitate stacking, separation, and transfer during automatic opening and closing processes.

[0028] The food bowl 1 can be used in two ways: First, it can be disposable, meaning that the bowl is discarded after each feeding and automatically collected in the collection container 41 by the recycling mechanism 4. Once a certain number of bowls have been collected in the collection container 41, the user can collect them and discard them, thus avoiding food residue and bacterial growth. Second, the food bowl 1 can be used non-disposable, meaning that the bowl is automatically collected by the recycling mechanism 4 after the pet finishes eating. The user can periodically collect the bowls from the collection container 41, clean and disinfect them, and then put them back into the storage bowl section 21 for reuse, thus balancing hygiene and economy.

[0029] In this embodiment, for ease of understanding and explanation, a round, disposable plastic bowl 1 is used as an example. This bowl 1 has a lightweight, thin-walled structure, and its rim has an outwardly folded flange to enhance stacking stability and separation reliability. However, those skilled in the art should understand that the above description of the shape, material, structure, and usage attributes of the bowl 1 is merely illustrative and not intended to limit the invention. Any form of bowl 1 capable of holding pet food and suitable for automatic stacking, separation, conveying, and collection should fall within the protection scope of this invention.

[0030] The placement mechanism 2 includes a storage bowl section 21, which is used to stack and accommodate multiple bowls 1 to continuously supply clean bowls 1 for automatic feeding operations. In this embodiment, the storage bowl section 21 has a cylindrical structure, with side walls and an internal accommodating space enclosed by the side walls. The cross-sectional shape of the internal accommodating space is adapted to the outer contour shape of the bowls 1, so that multiple bowls 1 stacked in a row can be neatly stacked coaxially within the storage bowl section 21.

[0031] The storage bowl section 21 extends vertically, with an inlet at the top for inserting the bowl 1 and an outlet 211 at the bottom for releasing the bowl 1. The outlet 211 is connected to the inlet, and the bowls 1 are stacked from top to bottom within the storage bowl section 21 under gravity. The bottom bowl 1 is located at the outlet 21 and awaits separation and release.

[0032] The bowl separation component 22 is located at the bowl outlet 211 at the bottom of the bowl storage section 21. The bowl separation component 22 includes a drive mechanism 221 and a switching wheel 222 driven by the drive mechanism 221. The switching wheel 222 is used to form a variable support relationship with the edges of the stacked bowls 1. Through its own rotational movement, it gradually guides the bottom bowl 1 from the supported state to the released state, thereby realizing the separation and falling of a single bowl 1.

[0033] In this embodiment, the switching wheel 222 is cylindrical, and a spiral guide surface 2221 extending spirally from top to bottom is provided on the side wall of the switching wheel 222. The spiral guide surface 2221 is a continuous curved surface that slopes downward along the circumference of the switching wheel 222. The uppermost end of the spiral guide surface 2221 is located on the upper part of the side wall of the switching wheel 222, and the lowermost end of the spiral guide surface 2221 extends to the bottom of the side wall of the switching wheel 222 or penetrates to the lower end face. When multiple bowls 1 are stacked in the storage bowl section 21, the edge flange of the bottommost bowl 1 rests on the uppermost end of the spiral guide surface 2221 of the switching wheel 222, and the uppermost area of ​​the spiral guide surface 2221 bears the weight of the bowl 1 and all the bowls 1 above it. When the drive mechanism 221 starts and drives the switching wheel 222 to rotate around its own axis, the spiral guide surface 2221 rotates accordingly. The edge of the bowl 1, which is placed on the spiral guide surface 2221, gradually slides down the spiral guide surface 2221 due to gravity and the continuous forward and downward movement of the spiral guide surface 2221, until it slides to the bottom of the spiral guide surface 2221 and completely detaches from the support of the switching wheel 222. Finally, it falls freely through the bowl outlet 211 to the placement station a. The moment the bowl 1 detaches, the adjacent bowl 1 above it falls immediately, and the edge of the bowl 1 lands on the top of the spiral guide surface 2221, entering the separation state. This cycle repeats, so that multiple bowls 1 can be separated one by one in an orderly manner.

[0034] To ensure that the bowl 1 remains stable and does not tilt or get stuck during the sliding process, the width of the spiral guide surface 2221 is adapted to the overlap width of the edge of the bowl 1. The surface of the spiral guide surface 2221 can be set as a smooth curved surface or have a friction-reducing coating to reduce sliding resistance.

[0035] The spiral angle of the spiral guide surface 2221 can be reasonably set according to the weight of the bowl 1 and the rotation speed of the drive mechanism 221. If the spiral angle is too large, the bowl 1 will slide down too fast and may fall off the correct position. If the spiral angle is too small, the separation efficiency will be reduced. In this embodiment, the spiral angle of the spiral guide surface 2221 is preferably in the range of 5 degrees to 15 degrees.

[0036] To further improve the uniformity and synchronization of support for the edge of the bowl 1, multiple switching wheels 222 are provided, and the multiple switching wheels 222 are arranged at intervals along the outer periphery of the bowl opening 211.

[0037] In this embodiment, the number of switching wheels 222 is preferably six, and each switching wheel 222 is arranged in a circular array with equal angles around the central axis of the bowl opening 211. The structures of each switching wheel 222 are exactly the same, and the starting height and spiral parameters of the spiral guide surface 2221 of each switching wheel 222 are consistent with each other.

[0038] The drive mechanism 221 can synchronously drive multiple switching wheels 222 to rotate around their own axis in the same direction and at the same speed, thereby ensuring that the edge of the bowl 1 obtains a uniform and consistent downward stroke at each support point, and avoiding the bowl 1 from tilting due to the lag or advance of the action of a single switching wheel 222.

[0039] Specifically, the drive mechanism 221 includes a first drive motor 2211, a driving gear 2212, a driven gear 2213, and a rotating shaft 2214 corresponding to each switching wheel 222. Specifically, the first drive motor 2211 serves as a power source, and its output end is coaxially and fixedly connected to the driving gear 2212 to drive the driving gear 2212 to rotate around its own axis. The driving gear 2212 meshes with the driven gear 2213 and transmits power to the driven gear 2213. The driven gear 2213 has a transmission groove 2215 extending circumferentially, which is annular or arc-shaped, and its inner wall has continuously distributed toothed structures. A rotating shaft 2214 is provided at the center of each switching wheel 222. Each rotating shaft 2214 extends vertically. The upper end or outer periphery of the rotating shaft 2214 is fixedly connected to the switching wheel 222, and the lower end of the rotating shaft 2214 passes into the transmission groove 2215 and meshes with the toothed structure on the inner wall of the transmission groove 2215.

[0040] When the first drive motor 2211 starts, the driving gear 2212 drives the driven gear 2213 to rotate. Since multiple rotating shafts 2214 are meshed with the inner wall of the transmission groove 2215, the rotation of the driven gear 2213 simultaneously drives all rotating shafts 2214 to rotate synchronously around their own axes through the transmission groove 2215, thereby driving each switching wheel 222 to rotate smoothly in the same direction and at the same speed. This transmission structure is simple and compact, requiring only a single motor to achieve precise synchronous control of multiple switching wheels 222, avoiding the phase deviation problem that may occur due to the use of multiple independent drive sources, and also reducing manufacturing costs and control complexity.

[0041] As a further refinement of this embodiment, the driven gear 2213 is configured as a large-diameter annular gear rotatable about its own central axis. The transmission groove 2215 of the driven gear 2213 is formed on the end face or near the edge of the driven gear 2213, and the centerline of the transmission groove 2215 coincides with the centerline of the driven gear 2213. A shaft gear 2216, matching the tooth profile of the inner wall of the transmission groove 2215, is sleeved on the outer periphery of the rotating shaft 2214. The shaft gear 2216 protrudes radially along the rotating shaft 2214, enabling stable meshing transmission with the tooth profile of the inner wall of the transmission groove 2215. When the driven gear 2213 rotates, the tooth profile of the inner wall of the transmission groove 2215 pushes the shaft gear 2216 on each rotating shaft 2214, thereby causing the rotating shaft 2214 to rotate.

[0042] It should be noted that, since the transmission groove 2215 extends continuously circumferentially, each rotating shaft 2214 rotates around its own axis while revolving with the driven gear 2213. The axis of the driven gear 2213 is parallel to but does not coincide with the axes of the rotating shafts 2214. This transmission method is essentially a variation of the planetary gear transmission principle. By appropriately setting the tooth ratio between the driving gear 2212 and the driven gear 2213, as well as the ratio of the number of teeth on the inner wall of the transmission groove 2215 to the number of teeth on the shaft gear 2216, the speed and direction of the switching wheel 222 can be precisely adjusted to match the working rhythm required for the separation of the bowl 1.

[0043] In a preferred embodiment, multiple switching wheels 222 are evenly distributed circumferentially around the central axis of the bowl opening 211, and each rotating shaft 2214 is correspondingly spaced along the same circumference. The driven gear 2213 can rotate freely, and its central axis coincides with the central axis of the bowl opening 211. The driving gear 2212 is mounted on the output shaft of the first drive motor 2211 and meshes with the outer edge gear ring of the driven gear 2213. The first drive motor 2211 operates in a stepping or continuous manner according to control commands, driving the driven gear 2213 to rotate through a predetermined angle each time it starts. This angle causes the switching wheel 222 to rotate one revolution or rotate a set angle corresponding to the separation stroke of the bowl 1.

[0044] Understandably, in order to ensure that each shaft 2214 always maintains a good meshing state in the transmission groove 2215, the diameter of the driven gear 2213 and the radial position of the transmission groove 2215 should match the distribution circumference of the shaft 2214 to avoid meshing interference or tooth disengagement.

[0045] As an alternative implementation, the transmission groove 2215 is not limited to being formed on the end face of the driven gear 2213; it can also be formed inside the side wall of the driven gear 2213 or use an independently set annular guide rail in conjunction with a toothed belt to achieve synchronous transmission. Furthermore, the meshing form between the driving gear 2212 and the driven gear 2213 is not limited to spur gears; it can also use helical gears, bevel gears, or worm gears to adapt to different spatial layout requirements. The rotating shaft 2214 corresponding to each switching wheel 222 does not necessarily use a shaft gear 2216 meshing with the transmission groove 2215; it can also use a friction wheel, synchronous pulley, or universal joint, as long as it can achieve synchronous drive of multiple rotating shafts 2214 by the driven gear 2213. Further details are omitted here.

[0046] In addition to the above embodiments, the specific structure of the bowl separating component 22 can also have various variations. For example, the spiral guide surface 2221 of the switching wheel 222 does not need to be a continuous spiral surface; it can also be a segmented stepped surface, providing a downward displacement every certain angle of rotation to achieve the step-by-step falling of the bowl 1. Furthermore, the drive mechanism 221 is not limited to being driven by a motor; it can also be driven by an electromagnet-driven ratchet mechanism, a pneumatic motor, or a hydraulic motor to achieve intermittent rotation of the switching wheel 222. Moreover, the contact form between the switching wheel 222 and the edge of the bowl 1 is not limited to overlapping; it can also be clamped or adsorbed, as long as it can cause the bowl 1 to produce a downward displacement during rotation.

[0047] In addition, to accommodate bowls 1 with different diameters or edge shapes, the mounting position of the switching wheel 222 on the rotating shaft 2214 can be set to adjustable. By adjusting the radial distance between the switching wheel 222 and the center of the bowl opening 211, the spiral guide surface 2221 can always form reliable contact with the edge of the bowl 1.

[0048] Furthermore, to ensure the continuity and reliability of the separation process of bowl 1, the descent stroke of the spiral guide surface 2221 is configured to be greater than the height of a single bowl 1. The descent stroke referred to here is the vertical distance between the uppermost and lowermost ends of the spiral guide surface 2221, which is greater than the height difference between the upper and lower surfaces of the bowl 1 edge or the spacing between adjacent bowls 1 in a stacked state. When the bottommost bowl 1 slides down the spiral guide surface 2221 and finally detaches, the bowl 1 completely loses support and falls freely to the placement station a the instant its edge leaves the switching wheel 222. At this time, because the descent stroke of the spiral guide surface 2221 is greater than the height of a single bowl 1, the next adjacent bowl 1 falls under gravity, and its edge lands precisely at the uppermost end of the spiral guide surface 2221, where it is then supported again by the switching wheel 222 and enters the separation state. This design effectively prevents the edge of the upper bowl 1 from dangling or colliding with the switching wheel 222 due to insufficient descent stroke, ensuring that the next bowl 1 can be accurately and smoothly positioned at the starting support position after each separation action.

[0049] Simultaneously, the rotation control of the switching wheel 222 by the drive mechanism 221 is configured to synchronize with the falling process of the bowl 1. Specifically, when the bottom bowl 1 slides down the spiral guide surface 2221 to the bottom and completely disengages from the switching wheel 222, the switching wheel 222 rotates exactly one revolution around its own axis or rotates to a predetermined angle position, causing the uppermost end of the spiral guide surface 2221 to rotate back to below the outlet 211 of the bowl storage section 21. In other words, at the same moment that the bowl 1 falls and is released, the upper surfaces of the spiral guide surfaces 2221 of all the switching wheels 222 also simultaneously return to the edge of the outlet 211, ready to receive the next bowl 1 falling from above. This synchronization effect can be achieved by reasonably setting the diameter of the switching wheel 222, the spiral helix angle and pitch of the spiral guide surface 2221, and the rotational speed of the drive mechanism 221, or by precisely adjusting the step angle of the drive motor using a controller.

[0050] The conveying mechanism 3 is located below the placement mechanism 2 and is used to receive the bowl 1 released from the bowl opening 211 and transport it sequentially to the feeding station b and the recycling station c.

[0051] In this embodiment, the conveying mechanism 3 includes a second drive motor 31 and a transmission turntable 32 driven to rotate by the second drive motor 31. The transmission turntable 32 has a disc-shaped or ring-shaped structure and can rotate around its own vertical axis.

[0052] The transmission turntable 32 has at least one bowl groove 33 along its circumference for limiting the bowl 1. The outline of the bowl groove 33 matches the overall shape of the bowl 1, so that the bowl 1 can be reliably positioned and kept upright after being placed in it, and is not easy to tip over or slip during the transmission process.

[0053] The output end of the second drive motor 31 is coaxially and fixedly connected to the center of the transmission turntable 32. When the second drive motor 31 starts, its output shaft drives the transmission turntable 32 to rotate around its own axis. The bowl trough 33 rotates synchronously with the transmission turntable 32, thereby switching cyclically between the placement station a, the feeding station b, and the recycling station c.

[0054] Specifically, placement station a is located directly below the bowl outlet 211 of the bowl storage section 21. When the bowl separation component 22 releases and drops a single bowl 1, the bowl 1 falls precisely into the bowl slot 33 located at placement station a. Subsequently, the second drive motor 31 drives the transmission turntable 32 to rotate through a predetermined angle, and the bowl slot 33 carrying the bowl 1 moves to feeding station b. Feeding station b is the area where the pet eats. Feeding station b is usually located at the front of the automatic feeding device or on a side easily accessible to the pet, where the bowl 1 rests for the pet to eat. After the preset feeding time ends or the pet is detected to have left, the second drive motor 31 drives the transmission turntable 32 to rotate again, moving the bowl slot 33 along with the used bowl 1 to recycling station c. Recycling station c corresponds directly above the top opening of the bowl collection container 41. When the bowl slot 33 reaches recycling station c, the bowl 1 loses its support and automatically falls into the receiving cavity of the bowl collection container 41, completing the recycling action. The empty bowl trough 33 can continue to rotate with the transmission turntable 32 back to the placement station a to receive the next bowl 1, thus realizing continuous cycle operation.

[0055] To accommodate different feeding frequencies and the needs of multi-pet ownership scenarios, the number of bowls 33 on the drive turntable 32 can be set to multiple. For example, in this embodiment, three bowls 33 are evenly spaced along the circumference of the drive turntable 32, corresponding to the simultaneous operation of three workstations: placement, feeding, and recycling. When the drive turntable 32 rotates 120 degrees, the three bowls 33 simultaneously switch to the next workstation, thereby realizing parallel processing in an assembly line and improving work efficiency.

[0056] Understandably, the number of bowls 33 is not limited to this. When a longer feeding interval or a larger workstation spacing is required, two, four, or more bowls 33 can be set up, simply by adjusting the rotation angle control strategy of the second drive motor 31 accordingly. The bottom of each bowl 33 can be further provided with a hollow structure or through holes to prevent the bowl 1 from adhering to the bottom surface of the bowl 33 due to water accumulation or foreign objects, ensuring that the bowl 1 can be smoothly detached at the recycling station c.

[0057] To ensure the positioning accuracy of the bowl trough 33 during station switching, a positioning recess corresponding to the position of the bowl trough 33 is provided below the transmission turntable 32. A spring ball or electromagnetic positioning pin is provided in the corresponding positioning recess. When the transmission turntable 32 rotates to the predetermined placement station a, feeding station b, or recycling station c, the spring ball or electromagnetic positioning pin can be engaged in the positioning recess to achieve temporary locking and prevent external interference from causing the bowl 1 to shift.

[0058] In addition, photoelectric sensors or proximity switches can be installed at each workstation to detect whether the bowl trough 33 is in place and whether the bowl 1 is present. The feedback signal is input to the controller to coordinate the timing of the actions of the placement mechanism 2 and the recycling mechanism 4.

[0059] It is understandable that the specific implementation of the conveying mechanism 3 is not limited to the aforementioned turntable structure. For example, in situations where space is limited or linear conveying is required, a linear guide rail combined with a sliding table can be used, with a synchronous belt or lead screw driving the bowl tray to pass through each station sequentially in a straight line. Furthermore, the bowl trough 33 does not necessarily have to be integrally formed with the transmission turntable 32; a detachable tray or bracket can also be used to facilitate cleaning and maintenance and accommodate bowls of different sizes 1.

[0060] The recycling mechanism 4 is located outside or below the conveying mechanism 3 and is used to collect the used bowls 1 that have been conveyed from the feeding station b.

[0061] In this embodiment, the recycling mechanism 4 includes a bowl collection container 41, which has a top-opening receiving cavity inside. The receiving cavity has sufficient volume to store multiple used bowls 1.

[0062] The specific shape of the bowl container 41 can be flexibly set according to the overall layout of the device. For example, it can be set as a cylindrical, square box or bucket-shaped structure with an opening at the top. The opening size of the bowl container 41 is not less than the maximum outer diameter of the bowl 1 to ensure that the bowl 1 can fall in smoothly.

[0063] Furthermore, the bottom of the bowl collection container 41 can be provided with a flat supporting surface or a guide surface that slopes from the edge to the center, so that the bowls 1 that fall in can automatically gather to the center of the bowl collection container 41, thereby making full use of the storage space of the receiving cavity.

[0064] In addition, the bowl collection container 41 can be made of transparent or semi-transparent plastic so that users can observe the accumulation of bowls 1 in the container at any time; graduation lines or overflow warning signs can also be set on the side wall of the container to further improve the convenience of use.

[0065] To accommodate scenarios requiring long-term unattended operation or the collection of large quantities of bowls 1 at once, the recycling mechanism 4 in this embodiment further includes a switching component 42. Multiple bowl collection containers 41 are provided, and the switching component 42 is connected to these containers. The switching component 42 can move multiple bowl collection containers 41, selectively moving one of them to the recycling station c. When a single bowl collection container 41 is full of bowls 1, it does not require immediate emptying by the user. Instead, the switching component 42 moves another empty container 41 to the recycling station c, thereby continuously performing the bowl 1 recycling operation and extending the device's continuous operating time.

[0066] As a preferred and easily implemented embodiment, the switching component 42 includes a third drive motor 421 and a recycling turntable 422. The recycling turntable 422 has a disc-shaped or ring-shaped structure and can rotate freely around its own vertical axis. Multiple collection bowl containers 41 are arranged circumferentially along the recycling turntable 422 and are fixed to the upper surface of the recycling turntable 422 or suspended from the outer edge of the recycling turntable 422 by a detachable connection. The output end of the third drive motor 421 is coaxially fixedly connected to the center of the recycling turntable 422. When the third drive motor 421 is started, its output shaft drives the recycling turntable 422 to rotate around its own axis, thereby causing the multiple collection bowl containers 41 to move circumferentially along the rotation path of the recycling turntable 422. By controlling the rotation angle of the third drive motor 421, any designated collection bowl container 41 can be moved to the recycling station c to receive the used bowls 1 falling from the conveying mechanism 3.

[0067] To achieve a detachable connection between the collection bowl container 41 and the recycling turntable 422, the upper surface of the recycling turntable 422 is provided with positioning grooves or positioning flanges corresponding to the positions of each collection bowl container 41, and the bottom of the collection bowl container 41 is provided with positioning protrusions or slots that match the grooves or flanges. The two can achieve dual positioning in the radial and circumferential directions through simple plug-in cooperation.

[0068] To further enhance connection reliability, the recycling turntable 422 can be equipped with elastic buckles, magnetic elements, or a twist-lock structure. Users can simply press down or rotate slightly to fix the bowl container 41 to the recycling turntable 422, and easily remove it by reversing the operation, facilitating the emptying of the bowl 1 and the washing of the container. In addition, the bowl container 41 itself can also be equipped with a handle or carrying handle structure to facilitate user transfer and emptying.

[0069] It is understandable that the specific implementation of the switching component 42 is not limited to the aforementioned turntable structure. For example, in cases where the spatial layout is arranged in a straight line, a linear guide rail combined with a sliding table can be used to arrange multiple collecting containers 41 in a row, and the sliding table can be driven to move linearly by a lead screw or synchronous belt, thereby achieving linear switching of the containers. Furthermore, the movement of the collecting containers 41 is not limited to horizontal rotation or linear translation; a lifting or swing arm switching structure can also be used, which will not be elaborated upon here.

[0070] The number of collection bowls 41 can be flexibly set according to actual needs, such as two, four or even more, simply by adjusting the size of the recycling turntable 422 and the control logic of the third drive motor 421 accordingly.

[0071] Furthermore, the automatic pet bowl disposal device of the present invention also includes a housing 5, which constitutes the external support frame and protective barrier of the device. The aforementioned placement mechanism 2, conveying mechanism 3, and recycling mechanism 4 are all housed within the internal space of the housing 5. The housing 5 not only integrates the various functional mechanisms into a single integrated product, making it compact and neat in appearance, but also effectively isolates external dust, debris, and accidental contact by pets, ensuring the stable and reliable operation of the internal mechanisms and the safety of use.

[0072] The housing 5 can be made of engineering plastics, metal sheets or composite materials. The overall shape of the housing 5 can be designed according to the layout of the internal mechanism, such as roughly a cuboid, cylinder or irregular polyhedron. It is only necessary to reserve sufficient space for the installation and operation of each mechanism while ensuring the structural strength.

[0073] The bottom of the housing 5 can be equipped with anti-slip pads or height-adjustable feet to adapt to different materials on the placement surface and maintain the device level.

[0074] To facilitate pets' eating at feeding station b, a feeding opening 51 connected to feeding station b is provided on the housing 5. The position of the feeding opening 51 corresponds to the position of the bowl trough 33 when the transmission turntable 32 rotates to feeding station b. The shape and size of the opening of the feeding opening 51 are designed so that the food bowl 1 located at feeding station b can be partially or completely exposed outside the housing 5 through the feeding opening 51, thereby allowing the pet to eat freely.

[0075] The feeding opening 51 can be designed as a rectangle, circle, or arch. The lower edge of the feeding opening 51 is roughly flush with or slightly lower than the rim of the bowl 1 to avoid uncomfortable contact between the pet's jaw and the edge of the shell 5 when eating. A soft protective sleeve, silicone edging, or a removable anti-chewing ring can also be installed around the feeding opening 51 to prevent the pet from being scratched by the edge of the shell 5 during eating, and also to prevent the pet from damaging the device by chewing on the shell 5.

[0076] In addition, a movable dustproof door or transparent soft curtain can be installed at the feeding port 51. When the bowl 1 is not in place, the dustproof door or transparent soft curtain is closed to prevent foreign objects from entering the interior of the housing 5. When the conveying mechanism 3 moves the bowl 1 to the feeding station b, the edge of the bowl 1 can push open the dustproof door or transparent soft curtain to expose it. After the bowl 1 is moved away, it automatically resets and closes, thus achieving the dual effect of dust prevention and aesthetics.

[0077] Meanwhile, to facilitate users in replenishing new bowls 1 to the bowl storage section 21, the housing 5 is also provided with a placement opening 52 that communicates with the bowl storage section 21. The placement opening 52 is located above the bowl opening of the bowl storage section 21, so users do not need to open the entire housing 5 or disassemble any parts; they can simply put stacks of bowls 1 into the bowl storage section 21 through the placement opening 52.

[0078] The placement opening 52 can be configured as an openable and closable structure, such as a flip-top, sliding, or screw-on lid. The lid and housing 5 are connected by hinges, guide rails, or snap-fits, and a sealing strip is provided on the edge of the lid to reduce dust intrusion. The lid can be made of a transparent material, allowing the user to observe the number of remaining bowls 1 in the storage bowl section 21 without opening the lid, so as to replenish them in time.

[0079] The opening size of the placement opening 52 should not be less than the maximum outer diameter of the bowl 1. If necessary, the placement opening 52 can be designed as a funnel-shaped or flared structure to guide the bowl 1 to slide smoothly into the storage bowl 21 without getting stuck.

[0080] In an alternative embodiment, the placement port 52 can also be directly opened on the top or side of the housing 5. The inner side of the placement port 52 is provided with a guide tube that is sealed and connected to the bowl opening of the storage bowl 21, thereby forming a complete bowl repair channel.

[0081] In a preferred embodiment, the housing 5 is provided with both a feeding port 51 and a placement port 52, which correspond to the feeding station b and the bowl 21, respectively. This allows both the pet's feeding and the user's bowl replenishment to be conveniently completed outside the housing 5 without disassembling the device. The feeding port 51 is typically located at the lower front of the housing 5 to accommodate the pet's habitual height when standing or bending over to eat. The placement port 52 is located at the top or upper side of the housing 5 to allow the user to naturally place the bowl 1 while standing.

[0082] It is understandable that, depending on the product positioning and application scenario, the housing 5 may only have a feeding port 51 or only a placement port 52. For example, in a design scheme that emphasizes the convenience of pet operation and adopts the method of refilling the bowl by pulling out the entire storage bowl 21, the placement port 52 can be omitted; conversely, in a design where the feeding station b is set inside the housing 5 and the pet eats by inserting its head, the feeding port 51 can also be omitted, which will not be elaborated here.

[0083] The housing 5 can also be further equipped with wiring channels, wire clips and electrical mounting plates to neatly store the connecting cables of the first drive motor 2211, the second drive motor 31, the third drive motor 421 and various electrical components, so as to avoid the cables from interfering with the motion mechanism.

[0084] Meanwhile, the housing 5 can be equipped with an openable maintenance door or a pull-out tray at the position corresponding to the recycling mechanism 4, so that users can periodically remove the collection container 41 for cleaning.

[0085] The specific types of the first drive motor 2211, the second drive motor 31 and the third drive motor 421 mentioned in this embodiment can be selected according to actual needs such as transmission load, control accuracy and installation space. For example, stepper motors or servo motors can be selected. The specific details of each drive motor and its control principle will not be elaborated in this invention.

[0086] It is understandable that the aforementioned placement station a is located directly below the bowl outlet 211 of the storage bowl section 21 and aligned with the vertical falling path of the bowl 1 released by the bowl separation component 22, to ensure that the bowl 1 released from the bowl outlet 211 can accurately fall into the bowl trough 33 that is currently resting at the placement station a. The feeding station b is located downstream of the placement station a along the movement direction of the conveyor mechanism 3. The feeding station b is internally and externally connected to the feeding port 51 opened on the housing 5 and is directly opposite the food outlet of the feeding control mechanism. When the bowl trough 33 carrying the bowl 1 moves to this position, the bowl 1 is just exposed outside the housing 5 through the feeding port 51 for the pet to eat, and at the same time, the pet food falling from the food outlet can also be accurately put into the bowl 1. The recycling station c is further located downstream of the feeding station b and directly above the top opening of the bowl collection container 41 of the recycling mechanism 4. When the used bowl 1 moves to this point with the bowl trough 33, the bowl 1 automatically detaches from the bowl trough 33 under the action of gravity and falls into the receiving cavity of the bowl collection container 41, completing the recycling operation.

[0087] The automatic pet bowl placement and collection device further includes a control system, which is electrically connected to the first drive motor 2211, the second drive motor 31, the third drive motor 421, and the sensors installed at each workstation, and is used to coordinate and control the timing and operating status of the placement mechanism 2, the conveying mechanism 3, and the collection mechanism 4.

[0088] The control system typically uses a microcontroller or programmable logic controller (PLC) as its core processing unit. It contains pre-installed control programs related to feeding time, workstation switching logic, and fault detection. For ease of operation and status monitoring, a control panel connected to the control unit can be installed on the housing 5. This control panel includes start, pause, and manual reset buttons, and can be configured with status indicator lights or a display screen to visually display the current operating mode, the number of remaining food bowls 1, and whether the collection container 41 is overflowing. Furthermore, the control system can integrate a wireless communication module, connecting to external terminals via infrared remote control, Bluetooth, Wi-Fi, or mobile communication networks. Users can remotely start feeding, check device status, receive replenishment reminders, or receive overflow alarms for the collection container 41 using a smartphone application or web interface, achieving intelligent and unmanned feeding management.

[0089] It should be noted that the button control circuit, remote control signal encoding and decoding, mobile application development, and remote control technology based on various communication protocols mentioned above are all well-known and mature technologies in the fields of automation control and Internet of Things applications. Therefore, this invention will not elaborate on the specific circuit structure of the control system, the detailed process of the control algorithm, and the specific implementation method of the application.

[0090] Example 2 Another specific embodiment of the present invention provides an automatic feeding device that integrates the functions of storing and quantitatively dispensing pet food with the aforementioned automatic pet bowl storage and dispensing device.

[0091] Specifically, the automatic feeding device includes a food storage bin, a feeding control mechanism, and an automatic pet bowl dispensing device provided in Embodiment 1.

[0092] The food storage bin is used to store pet food. The food storage bin can be a transparent or opaque box structure. The top of the food storage bin has an openable cover for easy refilling of food, and the bottom of the food storage bin forms a food outlet that connects to the feeding control mechanism.

[0093] The feeding control mechanism is connected to the food outlet of the food storage bin. The feeding control mechanism contains a metering component and an opening / closing component, used to dispense a fixed amount of pet food from the food storage bin according to a preset feeding plan. The food outlet of the feeding control mechanism corresponds to the feeding station b of the automatic bowl-collecting device provided in Embodiment 1, and the food outlet is located directly above or diagonally above the feeding station b, ensuring that the dispensed food accurately falls into the bowl 1 currently located at the feeding station b.

[0094] In actual operation, the automatic pet bowl placement and collection device first releases a clean bowl 1 into the bowl slot 33 of the conveying mechanism 3 via the placement mechanism 2. The conveying mechanism 3 then moves the bowl 1 to the feeding station b. Once the bowl 1 is in place, the feeding control mechanism opens the food outlet according to the internally set time or a received remote command. Pet food in the food storage bin is discharged under gravity or by a spiral push, falling into the bowl 1 below through the food outlet. The amount of food dispensed can be precisely controlled by adjusting the speed or opening time of the metering wheel in the feeding control mechanism. When the preset feeding amount is reached, the food outlet closes, and the pet can freely eat through the feeding opening 51 on the shell 5. After feeding, the conveying mechanism 3 removes the used bowl 1 from the feeding station b and continues to convey it to the recycling station c, where it is automatically collected by the recycling mechanism 4. At the same time, the placement mechanism 2 releases the next bowl 1, and the conveying mechanism 3 moves the bowl 1 to the feeding station b, preparing for the next meal.

[0095] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
