Abstract
Description
Technical Field
[0001] This utility model relates to the field of pet feeding equipment technology, and in particular to a pet feeder. Background Technology
[0002] As people's living standards improve, pet ownership has become a common lifestyle. In the field of pet feeders, especially for pets such as birds, most existing feeders adopt a gravity-feed structure, storing food in the upper food storage bin, and the food slides down to the lower food dish for the pet to eat by its own gravity.
[0003] However, these types of feeders have significant drawbacks. During feeding, pets produce food scraps, husks, and other residues, which mix with newly spilled food and accumulate in the dish. If not cleaned promptly, this mixture of food and scraps easily becomes damp, moldy, and spoils, affecting the pet's appetite and potentially harming its health. Therefore, frequent manual cleaning by pet owners is extremely inconvenient. Furthermore, these simple feeders typically lack remote control and timed / quantity settings, easily leading to food shortages when owners are away or neglect their pets.
[0004] To address these issues, some feeders with automatic cleaning functions have emerged. For example, some solutions use a movable pusher plate above the feeding dish to push leftover food into a collection box before feeding. However, this side-cleaning method suffers from incomplete cleaning, especially leaving residue in the corners of the dish. Furthermore, the pusher plate's mechanical structure is relatively complex, and food may get stuck during the pushing process, affecting the equipment's operational reliability. Utility Model Content

The food dispensing mechanism is located below the food dish and can connect or disconnect the food dish from the waste shell bin. In use, the pet feeder first connects the food dish and the waste shell bin via the food dispensing mechanism, allowing residual food or waste shells in the food dish to be discharged into the waste shell bin under gravity. Then, the food dish is disconnected from the waste shell bin, and the food conveying tray transports food flowing out of the storage bin to the food dish, thus allowing for refilling of the food dish. This device automatically and thoroughly empties waste shells and residue from the food dish before each addition of new food, fundamentally avoiding the problems of moisture and mold caused by the accumulation of mixed old and new food. This ensures the food is fresh and hygienic, guaranteeing that pets can always eat fresh, clean food, which is beneficial to their health. Compared to existing technologies that use side-cleaning methods such as push plates, this application uses a food discharge mechanism located under the food dish to empty the dish by gravity. This results in faster cleaning, no blind spots, and a more thorough cleaning. Furthermore, the simpler mechanical structure reduces the risk of malfunctions due to food blockage, improving the equipment's operational reliability, cleaning efficiency, and cleanliness.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0029] This embodiment provides a pet feeder, such as Figures 1-6 As shown, it includes a grain storage bin 1, a feeding tray 3, a waste shell bin 2, a grain transport tray 6, and a grain discharge mechanism 9.
[0030] The food storage bin 1, used to store pet food awaiting feeding, is injection molded from food-grade high-strength engineering plastics (such as acrylonitrile-butadiene-styrene copolymer) to ensure structural stability and food safety. The top of the food storage bin 1 is equipped with a removable food bin cover 11, which fits tightly with the opening edge of the food storage bin 1, effectively preventing external contaminants from entering and facilitating user refilling of food.
[0031] The grain conveying tray 6 is located below the grain storage bin 1 and is used to transport the grain flowing out of the grain storage bin 1 to the food tray 3. The grain conveying tray 6 is used to receive the grain that slips down due to gravity. Each time it rotates at a specific angle, it can carry and move a fixed amount of grain.
[0032] The food dish 3 is located below the food tray 6. It receives fresh food and serves as a feeding container for the pet. To ensure hygiene and ease of cleaning, the food dish 3 is preferably made of 304 stainless steel through a single stamping process. Its smooth surface prevents residue buildup and bacterial growth. The waste shell bin 2 is located below the food dish 3, and the food discharge mechanism 9 is located below the food dish 3, allowing the food dish 3 to connect to or separate from the waste shell bin 2.
[0033] In this embodiment of the pet feeder, the food tray 3 and the waste shell bin 2 are first connected by the food discharge mechanism 9, so that the food or waste shells left in the food tray 3 are discharged into the waste shell bin 2 under the action of gravity. Then the food tray 3 and the waste shell bin 2 are separated, and the food flowing out of the food storage bin 1 is transported to the food tray 3 by the food transport tray 6, thereby realizing the refilling of the food tray 3.
[0034] This pet feeder automatically and thoroughly empties waste shells and residue from the food dish before each addition of new food, fundamentally avoiding the problems of moisture and mold caused by the accumulation of mixed old and new food. This ensures the food is fresh and hygienic, guaranteeing that pets can always eat fresh, clean food, which is beneficial to their health. Compared to the side-cleaning methods such as push plates used in existing technologies, this application uses a food discharge mechanism located under the food dish to empty the dish by gravity. This results in faster cleaning, no blind spots, more thorough cleaning, and a simpler mechanical structure, reducing the risk of malfunctions due to food blockage, improving the reliability of the equipment, and enhancing cleaning efficiency and cleanliness.
[0035] As a preferred embodiment, such as Figure 2 As shown, a grain outlet 12 is provided on one side of the bottom of the grain storage silo 1, and a grain conveying silo 7 is provided below the grain storage silo 1. A grain discharge outlet 71 is provided on the bottom plate of the grain conveying silo 7 on the side opposite to the grain outlet 12. The grain conveying tray 6 is rotatably disposed in the grain conveying silo 7 and can open or close the grain outlet 12. When the grain outlet 12 is open, the grain conveying tray 6 rotates to push the flowing grain to the grain discharge outlet 71. One side of the feeding tray 3 extends to the lower side of the grain discharge outlet 71. Preferably, the grain conveying tray 6 includes two grain conveying blades 64, which are arranged opposite each other on both sides of its central axis, and the center lines of the two grain conveying blades 64 are on the same straight line passing through the central axis. When one grain conveying blade 64 is correspondingly blocked on the lower side of the grain outlet 12, the other grain conveying blade 64 is closed on the upper side of the grain discharge outlet 71.
[0036] Preferably, a positioning sensor 105 is provided on the lower side of the grain conveying pan 6. The positioning sensor is electrically connected to the control unit. The positioning sensor 105 can sense the rotation position of the grain conveying blade 64 of the grain conveying pan 6 in order to control the relative position of the grain conveying blade 64 with the grain outlet 12 and the grain discharge outlet 71.
[0037] In this embodiment, the grain conveying tray 6 can open or close the grain outlet 12 and the grain discharge outlet 71 by rotating the grain conveying bin 7. When the grain conveying tray 6 rotates to the position where the first conveying blade 64 opens the grain outlet 12, the grain in the grain storage bin 1 flows down through the grain outlet 12 into the grain conveying bin 7 under the action of gravity. The rotation of the grain conveying tray 6 drives the second conveying blade 64 to push the grain down to the grain discharge outlet 71, and transports the grain to the food tray 3 through the grain discharge outlet 71, thereby completing the process of transferring grain from the grain storage bin 1 to the food tray 3.
[0038] In a preferred embodiment, a grain discharge port 82 is provided at the bottom of the feeding tray 3, and a switch cover 42 is hinged to the grain discharge port 82. The grain discharge mechanism 9 can extend to the underside of the switch cover 42 and close the grain discharge port 82, or retract to the side of the switch cover to open the grain discharge port 82. The switch cover 42 is in the open state when it is not supported by the grain discharge mechanism 9. The grain discharge port 82 is closed by default under the support of the grain discharge mechanism 9 to ensure that the feeding tray 3 can normally hold grain, and its opening and closing are controlled by the grain discharge mechanism 9.
[0039] Preferably, the feeding dish 3 is cone-shaped, and the discharge port 82 is located at the bottom of the feeding dish 3 to facilitate emptying the leftover food in the feeding dish 3.
[0040] As a preferred embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, the grain discharge mechanism 9 includes a cam 91, a first elastic element 92, and a push-out lever 93. The first elastic element 92 can be a spring. The first end 931 of the push-out lever 93 can extend to the lower side of the switch cover, and the second end 932 abuts against the housing 5 through the first elastic element 92. The middle section of the push-out lever 93 is rotatably connected in the housing 5. The upper corner of the first end 931 of the push-out lever 93 is arc-shaped. The first end 931 of the push-out lever 93 is located near the side of the switch cover 42 with a hinge shaft, so that when the first end 931 of the push-out lever 93 extends, it can push the switch cover 42 to rotate and close the grain discharge port 82. The cam 91 can push the second end 932 of the push-out lever 93 and compress the first elastic element 92 to retract the first end 931 of the push-out lever 93 to the side of the switch cover.
[0041] When the cam 91 rotates to press the second end 932 of the push-out lever 93, the first elastic element 92 is compressed by force, and the first end 931 of the push-out lever 93 retracts to the side of the switch cover. At this time, the switch cover naturally opens the grain discharge port 82. When the cam 91 rotates to separate from the second end 932 of the push-out lever 93, the second end 932 of the push-out lever 93 moves into the machine compartment under the thrust of the first elastic element 92, and the first end 931 of the push-out lever 93 extends out to push the lower side of the switch cover, so that the switch cover closes the grain discharge port 82.
[0042] In a preferred embodiment, a lower grain silo 8 with an upward-facing opening is provided on the lower side of the feeding tray 3, and the grain discharge port 82 of the feeding tray 3 is correspondingly located at the opening of the lower grain silo 8. The bottom surface of the lower grain silo 8 is an inclined surface 81 sloping downwards towards the waste husk silo 2, and the grain discharge port 82 is provided at the bottom end of the inclined surface 81. The grain discharge port 82 is correspondingly located on the upper side of the waste husk silo 2. The first end 931 of the push-out lever 93 extends from the side wall of the lower grain silo 8 into the lower grain silo 8 to close the grain discharge port 82. The lower grain silo 8 can receive the grain and waste husks flowing out of the feeding tray 3 and transport them to the waste husk silo 2 under the action of gravity via the inclined surface 81. The upper opening structure of the waste husk silo 2 also facilitates disassembly and cleaning.
[0043] The waste husk compartment 2 is specifically a drawer-type structure. This compartment 2 has a large capacity and is used to collect all waste discharged from the feed outlet 82, including food scraps, grain husks, and a small amount of uneaten grain. When the feed outlet 82 is opened, all contents in the feed tray 3 will fall directly into the waste husk compartment 2 below under gravity. The waste husk compartment 2 is designed to be pulled out from the side or front of the feeder body, greatly facilitating regular centralized cleaning by the user. The drawer of the waste husk compartment 2 can be secured inside the outer casing with fasteners 21 to prevent the drawer from sliding out.
[0044] In a preferred embodiment, a dirt-proof cover 4 is provided on the upper side of the feeding dish 3. The dirt-proof cover 4 covers the upper side of the feeding dish 3, and a feeding opening 41 is provided on the side of the dirt-proof cover 4 away from the food storage bin 1. The dirt-proof cover 4 covers the feeding dish 3, leaving only the feeding opening 41 for the pet to peek into the food. Its function is twofold: firstly, to prevent external debris such as dust and hair from contaminating the food; secondly, to effectively prevent food or its husks from splashing out of the feeding dish when the pet is pecking at or shaking it, thereby keeping the surrounding environment clean.
[0045] In a preferred embodiment, the pet feeder of this example further includes a drive motor 10, which may have a reduction gear. A food storage bin 1 is positioned directly above a waste shell bin 2, and an intermediate bin 51 is formed between the food storage bin 1 and the waste shell bin 2, the intermediate bin 51 being disposed within the outer casing 5. A food tray 3 is disposed on one side of the intermediate bin 51 to facilitate pet feeding. The drive motor 10 is disposed within the intermediate bin 51. A cam 91 is coaxially arranged with the food conveying tray 6 and connected to the output shaft 101 of the drive motor 10. Alternatively, the cam 91 and the food conveying tray 6 may be driven by different motors.
[0046] The pet feeder in this embodiment makes full use of vertical space and uses the gravity of the food to transport it between different compartments. It has a compact structure and occupies little space.
[0047] As a preferred embodiment, such as Figure 2As shown, a connecting hole 61 is provided in the middle of the grain conveying tray 6. A connecting post 62 and a second elastic element 63 are provided in the connecting hole 61. The output shaft 101 of the drive motor 10 extends into the connecting hole 61. One end of the second elastic element 63 is connected to the connecting post 62 and the other end is connected to the output shaft 101 of the drive motor 10. The second elastic element 63 is a spring or other elastic element. The drive motor 10 can drive the grain conveying tray 6 and the cam 91 to rotate synchronously. When the cam 91 presses against the second end 932 of the push-out lever 93 and the switch cover opens the grain discharge port 82, one grain conveying blade 64 of the grain conveying tray 6 is correspondingly blocked on the lower side of the grain discharge port 12, and the other grain conveying blade 64 is closed on the upper side of the grain discharge port 71. Preferably, the grain discharge port 12 is fan-shaped, and a lower baffle 13 is provided on the lower side of the grain discharge port 12. The lower baffle 13 blocks both sides of the grain discharge port 12 and guides the flow of grain.
[0048] In this embodiment, the grain conveying tray 6 is vertically floatingly connected to the output shaft 101 of the drive motor 10 via the second elastic element 63, allowing the grain conveying blades 64 of the grain conveying tray 6 to rotate below the grain outlet 12 and abut against the lower baffles 13 on both sides of the grain outlet 12, thereby closing the grain outlet 12. Preferably, the grain conveying blades 64 of the grain conveying tray 6 have an arc-shaped structure on both sides to facilitate the rotation of the grain conveying blades 64 to the lower side of the lower baffles 13.
[0049] In a preferred embodiment, the output shaft 101 of the drive motor 10 extends through the bottom surface of the grain storage silo 1 and into the silo 1. A connecting cover 102 and multiple stirring rods 103 are provided in the grain storage silo 1. The stirring rods 103 are connected around the connecting cover 102, which is connected to the output shaft 101 of the drive motor 10. Preferably, a conical slope 14 is provided at the bottom of the grain storage silo 1 to gather grain towards the bottom of the silo 1. The multiple stirring rods 103 rest against the bottom surface of the grain storage silo 1 and are located within the area surrounded by the conical slope 14. The drive motor 10 can drive the multiple stirring rods 103 to rotate synchronously in the grain storage silo 1, pushing the grain in the grain storage silo 1 towards the grain outlet 12.
[0050] In a preferred embodiment, the pet feeder of this example also includes a control unit, with infrared photodiodes 15 arranged on both sides of the food storage compartment 1. The control unit includes a circuit board 104, which is disposed in the housing 5. A pair of infrared photodiodes for detecting the remaining food level is arranged on the lower side wall of the food storage compartment 1. Each infrared photodiode includes an infrared transmitter and an infrared receiver, which are mounted opposite each other on both sides of the inner wall of the food storage compartment 1. During normal operation, the transmitter emits an infrared beam. When the food level in the food storage compartment 1 is higher than the mounting position of the infrared photodiode, the light path is blocked; when the food level drops below this position, the light path is restored, and the receiver can receive the signal. The control unit is electrically connected to the infrared photodiodes 15 and the drive motor 10. Accordingly, the control unit can determine whether the remaining food level is lower than a preset warning threshold by monitoring the signal status changes of the receiver. The control unit includes a wireless communication module, which sends a low-food reminder signal to the user terminal.
[0051] Additionally, a weight sensor can be installed inside the feeding dish 3, located below the feeding dish 3 and above the waste shell compartment 2. This arrangement allows the weight sensor to measure the total weight of the feeding dish 3 and all its contents in real time and transmit this weight data to the control unit in the form of an electrical signal.
[0052] All the automated functions of this smart feeder are coordinated and executed by a built-in control unit. This control unit is typically a printed circuit board integrating a microcontroller, motor drive chip, power management unit, and sensor interface circuitry. In addition, the control unit also integrates a wireless module, such as a module supporting wireless communication protocols, enabling it to connect to a home wireless network. Through this wireless module, the feeder can communicate bidirectionally with an application on the user's smart device, allowing the user to remotely set feeding plans, manually trigger feeding or cleaning, and receive status notifications such as low food alerts and cleaning completion.
[0053] This automatic pet feeder, based on the time, frequency, and amount set by the user via a mobile app, first removes leftover food shells from food bowl 3 into the shell collection bin 2, then refills the food bowl with fresh food via an internal food conveyor. This ensures that the food in the bowl is, in most cases, fresh, which is beneficial to the pet's health. Furthermore, the centralized collection of shells in the shell collection bin prevents spillage and messy cleaning. This prevents pets from missing meals due to being away from home or forgetting to eat, and saves users the hassle of frequently cleaning food bowls and refilling food.
[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
