Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and more particularly to an automatic pet feeder. Background Technology

[0002] With the fast pace of modern life, more and more families are choosing to keep pets for companionship. However, pet ownership itself requires a significant investment of time and energy, and this burden is significantly amplified in multi-pet households. Ensuring that each pet receives food on time and in the correct amount has become a major challenge for pet owners. Currently, some owners still use traditional manual feeding methods, which are not only time-consuming and laborious but also difficult to guarantee inaccurate and consistent feeding. Other owners opt for automatic feeders on the market, but these products are primarily designed for single-pet households and fail to fully consider the specific needs of multi-pet families. For example, these automatic feeders typically only have a single feeding port, making it impossible to meet the feeding needs of different pets simultaneously. Therefore, developing an automatic feeder suitable for multi-pet households is particularly important. Summary of the Invention

[0003] In view of this, the present invention proposes an automatic pet feeder, which aims to solve the problem that existing automatic feeders cannot meet the feeding needs of multi-pet households.

[0004] This invention proposes an automatic pet feeder, comprising a food storage box, a control box, and a feeding box arranged sequentially from top to bottom; wherein, the food storage box is configured to connect to the lower food outlet of the control box, the control box is configured to connect to at least two food outlets of the feeding box, and the feeding box is configured to have at least two food trays, with each food tray corresponding to one of the food outlets; The control box contains a grain pushing structure and a grain distributing structure. The grain pushing structure includes a grain pusher and a first motor. The grain pusher includes a central shaft and at least two push rods, which are radially fixed to the central shaft. The central shaft is connected to the first motor, and the grain pusher can rotate around the first motor. The grain distributing structure includes a distributing disc, a connecting part, and a driving device. The connecting part is located at the bottom of the distributing disc, and the distributing disc can be driven to rotate by the driving device through the connecting part. The push rods are located inside the distributing disc, the central shaft passes through the distributing disc, and a distributing port is provided at the bottom of the distributing disc. When the grain distribution port is not connected to the grain outlet to be discharged, the grain distribution plate is driven to rotate by the driving device so that the grain distribution port can be connected to the grain outlet to be discharged; while the grain distribution plate is rotating, the grain pusher rotates around the first motor so that the top of the grain distribution port is always blocked by a push rod. When the food dispensing port is connected to the food outlet to be dispensed, the rotating food pusher will push the pet food that has fallen from the food outlet out of the food dispensing port and through the food outlet to the food bowl.

[0005] In one possible implementation, the control box is provided with three food outlets, and the feeding box is provided with three feeding trays; The feeding box also includes a base, the surface of which has a groove that matches the feeding dish, and the feeding dish is detachably connected to the base through the groove.

[0006] In one possible implementation, a gravity sensor is provided in the groove, and a camera is provided on one side of the food plate.

[0007] In one possible implementation, the driving device is a second motor, the connecting part is a transmission gear, the transmission gear is located at the center of the bottom of the grain distribution plate and is sleeved on the outside of the central shaft, and the grain distribution plate is driven to rotate by the meshing motion of the output shaft end gear of the second motor and the transmission gear.

[0008] In one possible implementation, the driving device is a pawl, and the connecting part is a ratchet. The ratchet is located at the center of the bottom of the grain distribution tray and is sleeved on the outside of the central shaft. When the first motor drives the grain pusher to rotate in the forward direction, the pawl engages between the teeth of the ratchet and pushes the grain distribution tray to rotate. When the first motor drives the grain pusher to rotate in the reverse direction, the pawl slides across the back of the teeth of the ratchet, and the grain distribution tray does not rotate.

[0009] In one possible implementation, the grain pusher includes four push rods, the height of which gradually increases outward from the central shaft. The surface of the grain pusher facing the grain distribution tray is provided with a graphite gasket. The grain storage box also includes a stirrer, which includes a central column and at least two blades. The blades are radially fixedly connected to the central column, which is fixedly connected above the central shaft and the two are concentrically arranged. The stirrer can rotate around the first motor.

[0010] In one possible implementation, the stirrer comprises three arc-shaped blades.

[0011] In one possible implementation, the grain storage box further includes a partition with an arc-shaped structure at its bottom. The arc-shaped structure and the central column are concentrically arranged, and the arc-shaped structure and the blades are separately arranged. The inner wall of the grain storage box is provided with a slot, and the partition can be inserted into or removed from the slot.

[0012] In one possible implementation, the top of the grain storage box is also provided with a perforated structure for placing a desiccant.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: An automatic pet feeder includes a food storage box, a control box, and a feeding box; the food storage box is provided with a food inlet, the control box is provided with at least two food outlets, and the feeding box is provided with at least two food trays; the control box is provided with a food pushing structure and a food dispensing structure; wherein, the food pushing structure includes a food pusher and a first motor, the food pusher includes a central shaft and at least two push rods, and the food pusher can rotate around the first motor; the food dispensing structure includes a food dispensing tray, a connecting part, and a driving device, and the food dispensing tray can be driven to rotate by the driving device through the connecting part; The push rod is located inside the food dispensing tray, and the central shaft passes through the tray. A food dispensing opening is located at the bottom of the tray. When the dispensing opening is not connected to the food outlet, the tray is driven to rotate by the drive device to connect the dispensing opening with the food outlet. Simultaneously, the pusher rotates around the first motor, ensuring that the top of the dispensing opening is always blocked by the push rod. When the dispensing opening connects with the food outlet, the rotating pusher pushes the pet food that has fallen from the lower food outlet out of the dispensing opening and through the food outlet to the food tray. Therefore, this automatic pet feeder has at least two food outlets, each corresponding to a food tray, ensuring that different pets can obtain their own food, thus meeting the feeding needs of multi-pet households. The rotating feed pusher pushes pet food that falls from the bottom of the feed chute through the dispensing chute to the outlet. The rotating feed tray precisely aligns the dispensing chute with the outlet, ensuring that pet food is accurately delivered to the designated feeding dish each time. Simultaneously, the pusher's lever blocks the dispensing chute, ensuring that the feeding channel remains blocked when the dispensing chute and outlet are not aligned. This prevents pet food from accidentally falling into the feeding dish and insects from entering the food container, thus improving the safety and hygiene of the feeding process.

[0019] Please refer to Figure 1-12 As shown, the present invention proposes an automatic pet feeder, comprising a food storage box 10, a control box 20, and a feeding box 30 arranged sequentially from top to bottom; wherein, the food storage box 10 is provided with a food outlet 11 for connecting to the control box 20, the control box 20 is provided with at least two food outlets 21 for connecting to the feeding box 30, and the feeding box 30 is provided with at least two food trays 31, the food trays 31 and the food outlets 21 corresponding one-to-one; The control box 20 is equipped with a grain pushing structure and a grain distributing structure. The grain pushing structure includes a grain pusher and a first motor 23. The grain pusher includes a central shaft 221 and at least two push rods 222. The push rods 222 are radially fixedly connected to the central shaft 221. The central shaft 221 is connected to the first motor 23, and the grain pusher can rotate around the first motor 23. The grain distributing structure includes a grain distributing disc 24, a connecting part, and a driving device. The connecting part is located at the bottom of the grain distributing disc 24, and the grain distributing disc 24 can be driven to rotate by the driving device through the connecting part. The push rods 222 are located inside the grain distributing disc 24, the central shaft 221 passes through the grain distributing disc 24, and a grain distributing port 241 is provided at the bottom of the grain distributing disc 24. When the grain distribution port 241 is not connected to the grain outlet 21 to be discharged, the grain distribution plate 24 is driven to rotate by the driving device so that the grain distribution port 241 is connected to the grain outlet 21 to be discharged; while the grain distribution plate 24 rotates, the grain pusher rotates around the first motor 23 so that the top of the grain distribution port 241 is always blocked by a push rod 222. When the food dispensing port 241 is connected to the food outlet 21, the rotating food pusher will push the pet food that has fallen from the food outlet 11 out of the food dispensing port 241 and through the food outlet 21 to the food bowl 31.

[0020] Specifically, the food storage box 10, control box 20, and feeding box 30 are the three components of the automatic pet feeder. The food storage box 10 is used to store pet food, the control box 20 houses various controllers and drive modules, and the feeding box 30 provides the pet with a feeding environment. To maintain the cleanliness and hygiene of the overall product structure, the parts in contact with pet food in the food storage box 10, feeding box 30, and control box 20 are designed for easy disassembly and cleaning.

[0021] Specifically, since the control box 20 has at least two food outlets 21, when feeding different pets, it is necessary to rotate the food dispensing tray 24 to turn the food dispensing tray 241 to different food outlets 21, so as to deliver pet food to their respective food bowls 31 and meet the feeding needs of different pets. During the rotation of the food dispensing tray 24, to prevent pet food from accidentally falling, the food dispensing tray 241 should remain blocked by the push rod 222. When the automatic pet feeder is not working, the food dispensing tray 241 should also be kept away from being below the food inlet 11. At the same time, the food dispensing tray 241 can still remain blocked by the push rod 222 to further ensure the hygiene and safety of the pet food. It should be noted that the food outlet 21 adopts a downward sloping design to utilize gravity to allow the pet food to slide more smoothly into the food bowl 31, making it easier for the pet to eat.

[0022] Compared with existing technologies, the automatic pet feeder proposed in this embodiment has at least two food outlets 21, each corresponding to a food dish 31, to ensure that different pets can obtain their own pet food, thereby meeting the feeding needs of multi-pet households. The rotation of the feed pusher can push the pet food falling from the lower food outlet 11 through the food distribution outlet 241 to the food outlet 21, while the rotation of the food distribution dish 24 can precisely align the food distribution outlet 241 with the food outlet 21 to be dispensed, ensuring that the pet food is accurately delivered to the designated food dish 31 each time. At the same time, the push rod 222 of the feed pusher blocks the food distribution outlet 241, ensuring that the food dispensing channel is always blocked when the food distribution outlet 241 is not connected to the food outlet 21 to be dispensed, preventing pet food from accidentally falling into the food dish 31 and insects from flying into the pet food, thereby improving the safety and hygiene of the feeding process.

[0023] In some embodiments of this application, the control box 20 is provided with three food outlets 21, and the feeding box 30 is provided with three feeding trays 31; The feeding box 30 also includes a base 32, the surface of which is provided with a groove 321 that matches the feeding dish 31, and the feeding dish 31 is detachably connected to the base 32 through the groove 321.

[0024] For details, please refer to Figure 3As shown, the feeding box 30 has three feeding positions for pets, i.e., three food trays 31. The food trays 31 are used to collect pet food that falls from the food outlet 21 and can be easily removed from the base 32 for cleaning.

[0025] In some embodiments of this application, a gravity sensor is provided in the groove 321, and a camera is provided on one side of the food plate 31.

[0026] Specifically, by installing a gravity sensor in the recess 321 at the bottom of the food dish 31, the pet's food intake can be monitored in real time, helping owners better understand their pet's eating habits. Furthermore, the feeding box 30 can be equipped with a visual recognition system, such as a camera, to identify and record the pet's eating behavior. By adding a camera to the front of the automatic pet feeder, the eating habits of different pets can be statistically analyzed, and software analysis can better meet the needs of automated feeding. The combination of these functions will provide a more intelligent management solution for feeding multiple pets.

[0027] In some embodiments of this application, the driving device is a second motor 251, the connecting part is a transmission gear 252, the transmission gear 252 is located at the center of the bottom of the grain distribution plate 24 and is sleeved on the outside of the central shaft 221, and the grain distribution plate 24 is driven to rotate by the meshing motion of the output shaft end gear 2511 of the second motor 251 and the transmission gear 252.

[0028] For details, please refer to Figure 4 and Figure 5 As shown, the control box 20 contains a motor mounting plate 254, a feed pusher (including a central shaft 221 and a push rod 222), a first motor 23, a connector 255, a second motor 251 (equipped with an output shaft end gear 2511), a transmission gear 252, a main bearing, a feed distribution bearing, and a feed distribution tray 24. The first motor 23 is mounted on the motor mounting plate 254, and the central shaft 221 is mounted on the motor mounting plate 254 via the main bearing. The first motor 23 is mounted directly below the main bearing. The first motor 23 drives the push rod 222 of the feed pusher and the blades 122 of the stirrer in the food storage box 10 to rotate via the central shaft 221. The second motor 251 controls the transmission gear 252 to rotate via the output shaft end gear 2511, thereby driving the feed distribution tray 24 to rotate. Rotation of the feed distribution tray 24 changes the position of the feed outlet 241, allowing pet food to be fed into the designated feed tray 31 corresponding to the designated outlet 21.

[0029] In some embodiments of this application, the driving device is a pawl 261, and the connecting part is a ratchet 262. The ratchet 262 is located at the center of the bottom of the grain distribution disc 24 and is sleeved on the outside of the central shaft 221. When the first motor 23 drives the grain pusher to rotate in the forward direction, the pawl 261 engages between the teeth of the ratchet 262 and pushes the grain distribution disc 24 to rotate. When the first motor 23 drives the grain pusher to rotate in the reverse direction, the pawl 261 slides across the back of the teeth of the ratchet 262, and the grain distribution disc 24 does not rotate.

[0030] For details, please refer to Figure 6 As shown, a ratchet 262 is installed at the center of the bottom of the grain distribution tray 24, and a pawl 261 is installed on one side of the bottom of the grain distribution tray 24 by screws. When the first motor 23 rotates forward, the pawl 261 engages between the teeth of the ratchet 262, pushing the grain distribution tray 24 to rotate. At this time, the agitator and the grain pusher rotate together. When the first motor 23 rotates in reverse, the ratchet 262 rotates with the central shaft 221, and the pawl 261 slides on the back of the teeth of the ratchet 262, so the grain distribution tray 24 does not rotate.

[0031] In some embodiments of this application, the grain pusher includes four push rods 222, the height of which gradually increases outward from the central shaft 221, and the surface of the grain pusher facing the grain distribution plate 24 is provided with a graphite pad.

[0032] Specifically, the push rod 222 has a hill-shaped structure. The grain pusher is installed inside the grain distribution plate 24 and can be driven by the first motor 23 to rotate within the grain distribution plate 24. A graphite gasket or similar smooth material is provided on the surface of the grain pusher that contacts the grain distribution plate 24 to reduce friction between the grain pusher and the grain distribution plate 24, improving the smoothness and reliability of the grain pusher's movement. The central shaft 221 of the grain pusher can be connected and tightened with other components through various methods such as nuts, clips, and spring pins, ensuring that the grain pusher can be easily disassembled.

[0033] For details, please refer to Figure 7 and Figure 8As shown, a motor mounting plate 254 is installed in the central area inside the control box 20. The motor mounting plate 254 is connected to the housing of the control box 20 by screws. A main bearing is installed in the middle of the motor mounting plate 254, and a first motor 23 is installed directly below the main bearing. The outer circle of the main bearing is mounted on the motor mounting plate 254, and the center circle is mounted on the central shaft 221. One end of the central shaft 221 is mounted on the first motor 23 and is driven by the first motor 23. A grain distribution bearing is also installed on the central shaft 221, located above the main bearing. The center circle of the grain distribution bearing is mounted on the central shaft 221, and a connector 255 is installed on its outer circle. A second motor 251 is installed next to the first motor 23, below the motor mounting plate 254. The output shaft gear 2511 of the second motor 251 passes through the motor mounting plate 254 and meshes with the transmission gear 252. The connector 255 is located above the motor mounting plate 254 and is not driven by the first motor 23. The connector 255 has a protrusion on its upper part. Below the grain distribution tray 24 is a groove 253 that can engage with the protrusion. Below the grain distribution tray 24 is a transmission gear 252, which meshes with the output shaft gear 2511 of the second motor 251 and is controlled by the second motor 251 to rotate.

[0034] In some embodiments of this application, the grain storage box 10 further includes a stirrer, which includes a central column 121 and at least two blades 122. The blades 122 are radially fixedly connected to the central column 121. The central column 121 is fixedly connected above the central shaft 221 and the two are concentrically arranged. The stirrer can rotate around the first motor 23.

[0035] For details, please refer to Figures 9 to 12 As shown, a stirrer is installed at the bottom of the food storage box 10. The stirrer is mounted on the central shaft 221 and fixed with a nut, allowing it to rotate with the central shaft 221. The food inlet 11 is located below the stirrer blades 122. When the stirrer rotates, it causes the pet food in the food storage box 10 to fall from the food inlet 11 to the food distribution tray 24. Simultaneously, the food pusher rotates and pushes the fallen pet food from the food distribution tray 241 to the food outlet 21, and then to the food tray 31 above the feeding box 30, making it convenient for the pet to eat. The control box 20 has a brush 27 above the food pusher, which is installed below the food storage box 10. The brush 27 is located between the food storage box 10 and the food pusher and is in contact with the food pusher. When the pet food gets stuck on the food pusher, the brush 27 can easily sweep the pet food off. The control box 20 can also have two brushes 27 arranged in a V-shape. This distribution ensures that the brush 27 better covers the entire surface of the feed pusher, effectively clearing blockages and improving the flow of pet food and the smoothness of feeding, regardless of where the pet food falls.

[0036] In some embodiments of this application, the stirrer includes three arc-shaped blades 122.

[0037] Specifically, the food storage box 10 is mounted above the control box 20 and connected by a simple method such as a snap-fit ​​or thread. The stirrer and the feed pusher are driven together by the first motor 23. The design of the blades 122 is not limited to a three-blade arc structure; different shapes and numbers can be selected according to actual needs, such as four blades, five blades, or other polygonal structures, to better adapt to different types of pets and feeding needs.

[0038] In some embodiments of this application, the grain storage box 10 further includes a partition 13, the bottom of which is provided with an arc-shaped structure 131. The arc-shaped structure 131 and the central column 121 are concentrically arranged and the arc-shaped structure 131 and the blade 122 are separately arranged. The inner wall of the grain storage box 10 is provided with a slot 14, and the partition 13 can be inserted into or removed from the slot 14.

[0039] Specifically, the food storage box 10 can be equipped with one or more dividers 13. Users can insert or remove several dividers 13 according to actual needs to store various types of pet food, making it convenient for pets to eat a variety of foods together.

[0040] In some embodiments of this application, the top of the grain storage box 10 is also provided with a perforated structure 15 for placing a desiccant.

[0041] Specifically, the perforated structure 15 can be set on the lid above the food storage box 10, forming a receiving cavity with the perforated structure 15. Placing a desiccant inside the receiving cavity can effectively absorb moisture, keeping the pet food in the food storage box 10 dry and fresh, ensuring that the pet can obtain better taste and nutrition when eating.

[0042] The automatic pet feeder provided in this embodiment is a timed and quantitative automatic feeder suitable for multi-pet households, bringing a more convenient and intelligent feeding experience. It is an innovative and practical pet product. To meet the feeding needs of multi-pet households, this automatic pet feeder is designed with three feeding ports (i.e., three food trays 31). Users can control the amount of pet food provided by each feeding port through function settings, while also meeting the feeding requirements of single-pet households. To meet the needs of multi-pet households for long-term feeding, the food storage box 10 of this automatic pet feeder is designed with a large-capacity food storage compartment, effectively avoiding the hassle of frequent pet food replenishment. At the same time, the food storage box 10 adopts a sealed design to effectively prevent pet food from getting damp and spoiling. All components of this automatic pet feeder are designed for easy disassembly and cleaning, facilitating daily maintenance and cleaning by users and ensuring the hygiene of the pet's diet.

[0043] The following details three common ways to use this automatic pet feeder: Before starting the automatic pet feeder, users can place pet food in the food storage box 10 and set the feeding function.

[0044] Method 1: When the set feeding time is reached and there is no need to switch the food outlet 21, the automatic pet feeder will start automatically. The first motor 23 will start working, driving the stirrer and the food pusher to rotate together. The pet food will fall through the food outlet 11 into the food distribution tray 24. The food pusher rotating in the food distribution tray 24 will push the pet food from the food distribution outlet 241 to the food outlet 21, and finally deliver the pet food to the food dish 31 above the feeding box 30 for the pet to eat.

[0045] Method 2: When the set feeding time arrives and it is necessary to switch the food outlet 21, the second motor 251 starts working, driving the food distribution tray 24 to rotate and change the position of the food outlet 241, thus connecting it with a different food outlet 21. At the same time, the first motor 23 also works, driving the stirrer and the food pusher to rotate synchronously, ensuring that the food pusher always covers the food outlet 241 to prevent pet food from falling or insects from entering.

[0046] It should be noted that when the steps of method 2 are completed, the food dispensing port 241 will reach the designated position and connect with the specific food outlet 21. At this time, the steps of method 1 need to be performed again to deliver the pet food to the specific food dish 31 above the feeding box 30.

[0047] Method 3: Users can modify the program to set the amount of food received in each food dish 31. Specifically, users can set the number of portions of pet food that fall into the food dish 31. When the first motor 23 starts, it will drive the mixer and the food pusher to rotate together. The first portion of pet food that falls from the food outlet 21 is counted as 1 portion. The next portion of pet food that falls after the first motor 23 continues to run is counted as 2 portions, and so on. Users can set different amounts of food received in each of the three food dishes 31, i.e., the number of portions of pet food that fall, to meet the dietary needs of different pets.

[0048] For single-pet households, only one food dish 31 needs to be set up to accept one serving of pet food, while the other food dishes 31 remain empty. In this case, the automatic pet feeder simply needs to repeat the steps in usage method 1 to automatically feed the single pet.

[0049] For multi-pet households, such as those with three pets, the three food bowls 31 can be designated as No. 1, No. 2, and No. 3. Due to different pets' eating habits, the three food bowls 31 are respectively set to receive 1 portion of pet food, 2 portions, and 3 portions. First, the automatic pet feeder executes step 2 of usage mode once, switching the food dispensing port 241 to the position corresponding to the food outlet 21 of food bowl 1, and then executes step 1 of usage mode once. Next, the automatic pet feeder executes step 2 of usage mode once, switching the food dispensing port 241 to the position corresponding to the food outlet 21 of food bowl 2, and then executes step 1 of usage mode twice. Finally, the automatic pet feeder executes step 2 of usage mode once, switching the food dispensing port 241 to the position corresponding to the food outlet 21 of food bowl 3, and then executes step 1 of usage mode three times. This achieves the purpose of the three food bowls 31 receiving 1, 2, and 3 portions of pet food respectively. The automatic pet feeder only needs to repeat the above steps to automatically feed multiple pets.

[0050] The automatic pet feeder provided in this embodiment is optimized for the specific needs of multi-pet households, featuring three feeding ports, intelligent control, a large-capacity food storage bin, easy cleaning, and pet recognition. This product has broad application prospects in the market, not only meeting the feeding needs of multi-pet households but also improving the quality of life for pet owners and reducing their daily burden.
