Description

Technical Field

[0001] The present invention relates to the technical field of pet supplies, and particularly to an automatic pet feeder. Background Art

[0002] With the acceleration of the modern life rhythm, more and more families choose to raise pets to accompany their lives. However, raising pets itself requires a lot of time and energy, and in multi-pet families, this burden is significantly increased. How to ensure that each pet can obtain food on time and in a fixed amount has become a major challenge for pet owners. At present, some owners still adopt the traditional manual feeding method, which is not only time-consuming and laborious, but also difficult to ensure the accuracy and regularity of feeding. Other owners choose automatic feeders on the market, but these products are mainly designed for single-pet families and do not fully consider the special needs of multi-pet families. For example, these automatic feeders usually only have a single feeding port and cannot meet the feeding needs of different pets at the same time. Therefore, it is particularly important to develop an automatic feeder suitable for multi-pet families. Summary of the Invention

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Please refer to Figure 1-12 As shown, the present invention provides a pet automatic feeder, which includes a grain storage box 10, a control box 20, and a feeding box 30 arranged in sequence from top to bottom; wherein, the grain storage box 10 is provided with a grain outlet 11 for communicating with the control box 20, the control box 20 is provided with at least two grain outlets 21 for communicating with the feeding box 30, the feeding box 30 is provided with at least two food trays 31, and the food trays 31 and the grain outlets 21 correspond one by one;

[0040] A grain pushing structure and a grain distributing structure are arranged in the control box 20; wherein, the grain pushing structure includes a grain pusher and a motor 23, the grain pusher includes a central shaft body 221 and at least two push rods 222, the push rods 222 are fixedly connected to the central shaft body 221 in a radial manner, the central shaft body 221 is connected to the motor 23 and the grain pusher can rotate around the motor 23; the grain distributing structure includes a grain distributing plate 24, a connecting part, and a driving device, the connecting part is located at the bottom of the grain distributing plate 24 and the grain distributing plate 24 can be driven to rotate by the driving device through the connecting part; the push rods 222 are located in the grain distributing plate 24, the central shaft body 221 penetrates through the grain distributing plate 24, and a grain distributing opening 241 is arranged at the bottom of the grain distributing plate 24;

[0041] When the grain dispensing opening 241 is not connected to the grain dispensing opening 21 to be discharged, the grain dispensing plate 24 is driven to rotate by the driving device so as to connect the grain dispensing opening 241 with the grain dispensing opening 21 to be discharged; while the grain dispensing plate 24 rotates, the grain pusher rotates around the motor 23 so that the top of the grain dispensing opening 241 is always blocked by a push rod 222;

[0042] When the food dispensing port 241 is connected to the food dispensing port 21 to be dispensed, the rotating food pusher pushes the pet food dropped from the lower food port 11 out of the food dispensing port 241 and reaches the food tray 31 through the food dispensing port 21 to be dispensed.

[0043] Specifically, the grain storage box 10, the control box 20 and the feeding box 30 are three components of the automatic pet feeder. The grain storage box 10 is used to store pet food, the control box 20 is equipped with various controllers and drive modules, and the feeding box 30 provides a feeding environment for the pet. In order to keep the overall structure of the product clean and hygienic, the grain storage box 10, the feeding box 30 and the parts of the control box 20 that come into contact with the pet food are designed to be easy to disassemble and clean.

[0044] Specifically, since the control box 20 is provided with at least two grain outlets 21, when feeding different pets, it is necessary to rotate the grain distribution plate 24 to transfer the grain distribution port 241 to different grain outlets 21, so as to deliver the pet food to the respective food trays 31 to meet the feeding needs of different pets. During the rotation of the grain distribution plate 24, in order to prevent the pet food from accidentally falling, the grain distribution port 241 should remain blocked by the push rod 222. When the automatic pet feeder is not working, the grain distribution port 241 should also be avoided as much as possible from being below the lower grain port 11. At the same time, the grain distribution port 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 grain outlet 21 adopts a downwardly inclined slope design, so that gravity can be used to make the pet food slide down to the food tray 31 more smoothly, which is convenient for the pet to eat.

[0045] Compared with the prior art, the pet automatic feeder proposed in this embodiment is provided with at least two grain outlets 21, and each grain outlet 21 corresponds to a food tray 31, so as to ensure that different pets can obtain pet food respectively, thereby meeting the feeding needs of multi-pet families. The rotation of the pusher can push the pet food dropped from the lower grain outlet 11 out to the grain outlet 21 through the grain distribution port 241, and the rotation of the grain distribution plate 24 can accurately dock the grain distribution port 241 with the grain outlet 21 to be discharged, so as to ensure that the pet food can be accurately delivered to the designated food tray 31 every time when feeding. At the same time, the blocking of the push rod 222 of the pusher on the grain distribution port 241 can ensure that the grain outlet channel is always blocked when the grain distribution port 241 is not connected to the grain outlet 21 to be discharged, preventing the pet food from accidentally falling into the food tray 31 and insects from flying into the pet food, thereby improving the safety and hygiene of the feeding process.

[0046] In some embodiments of the present application, the control box 20 is provided with three grain outlets 21, and the feeding box 30 is provided with three food trays 31;

[0047] The feeding box 30 further includes a base 32, and the surface of the base 32 is provided with a groove 321 matching the food tray 31, and the food tray 31 is detachably connected to the base 32 through the groove 321.

[0048] Specifically, please refer to Figure 3 As shown, the feeding box 30 is provided with three pet feeding positions, that is, three food trays 31 are provided. The food tray 31 is used to collect the pet food dropped from the grain outlet 21 and can be easily removed from the base 32 for cleaning.

[0049] In some embodiments of the present application, the groove 321 is provided with a gravity sensor, and a camera is provided on one side of the food tray 31.

[0050] Specifically, installing the gravity sensor in the groove 321 and at the bottom of the food tray 31 can real-time monitor the pet's food intake and help the owner better master the pet's diet. In addition, the feeding box 30 can also be equipped with a visual recognition system, such as installing a camera, so as to identify and record the pet's diet. By adding a camera in the front of the pet automatic feeder, the eating habits of different pets can be counted and analyzed through software to better meet the needs of automatic feeding. The combination of these functions will provide a more intelligent management solution for the feeding of multiple pets.

[0051] In some embodiments of the present application, the driving device is a motor 251, the connecting part is a transmission gear 252, the transmission gear 252 is located at the center position of the bottom of the grain distribution plate 24 and is sleeved outside the central shaft body 221, and the grain distribution plate 24 is driven to rotate by the meshing movement of the output shaft gear 2511 of the motor 251 and the transmission gear 252.

[0052] Specifically, please refer to Figure 4 and Figure 5 As shown, inside the control box 20, there are installed a motor mounting plate 254, a grain pusher (including a central shaft body 221 and a push rod 222), a motor 23, a connector 255, a motor 251 (equipped with an output shaft end gear 2511), a transmission gear 252, a main bearing, a grain distribution bearing, and a grain distribution plate 24. The motor 23 is installed on the motor mounting plate 254. The central shaft body 221 is installed on the motor mounting plate 254 through the main bearing. The motor 23 is installed directly below the main bearing. The motor 23 drives the push rod 222 of the grain pusher and the blade 122 of the stirrer in the grain storage box 10 to rotate through the central shaft body 221. The motor 251 controls the rotation of the transmission gear 252 through the output shaft end gear 2511, thereby driving the rotation of the grain distribution plate 24. When the grain distribution plate 24 rotates, the position of the grain distribution port 241 can be changed, and the pet food is guided into the food tray 31 corresponding to the designated grain outlet 21.

[0053] In some embodiments of the present application, the driving device is a ratchet pawl 261, and the connecting portion is a ratchet wheel 262. The ratchet wheel 262 is located at the central position of the bottom of the grain distribution plate 24 and is sleeved outside the central shaft body 221. When the motor 23 drives the grain pusher to rotate forward, the ratchet pawl 261 is embedded between the teeth of the ratchet wheel 262 and pushes the grain distribution plate 24 to rotate. When the motor 23 drives the grain pusher to rotate in reverse, the ratchet pawl 261 slides over the tooth back of the ratchet wheel 262, and the grain distribution plate 24 does not rotate.

[0054] Specifically, please refer to Figure 6 As shown, the ratchet wheel 262 is installed at the central position of the bottom of the grain distribution plate 24, and one side of the bottom of the grain distribution plate 24 is installed with the ratchet pawl 261 through screws. When the motor 23 rotates forward, the ratchet pawl 261 is embedded between the teeth of the ratchet wheel 262, pushing the grain distribution plate 24 to rotate. At this time, the stirrer and the grain pusher rotate together. When the motor 23 rotates in reverse, the ratchet wheel 262 rotates together with the central shaft body 221, and the ratchet pawl 261 slides over the tooth back of the ratchet wheel 262, and the grain distribution plate 24 does not rotate.

[0055] In some embodiments of the present application, the grain pusher includes four push rods 222. The height of the push rod 222 gradually increases outward from the central shaft body 221. The surface of the grain pusher facing the grain distribution plate 24 is provided with a graphite gasket.

[0056] Specifically, the structure of the push rod 222 is similar to a hill-shaped structure. The grain pusher is installed inside the grain distribution plate 24 and can be driven by the motor 23 to rotate inside the grain distribution plate 24. A graphite gasket or a similar smooth material flat gasket is provided on the surface in contact with the grain distribution plate 24 below the grain pusher to reduce the friction between the grain pusher and the grain distribution plate 24 and improve the movement smoothness and reliability of the grain pusher. The central shaft body 221 of the grain pusher can be connected and pressed with other components in various ways such as nuts, buckles, spring pins, etc., and it is ensured that the grain pusher can be easily disassembled.

[0057] In some embodiments of the present application, the control box 20 further includes a brush 27, and the brush 27 is located between the grain storage box 10 and the grain pusher and contacts the grain pusher.

[0058] Specifically, please refer to Figure 7 and Figure 8 As shown, a motor mounting plate 254 is installed in the middle 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. The motor 23 is installed directly below the main bearing. The outer circle of the main bearing is installed on the motor mounting plate 254, and the central circle is installed on the central shaft body 221. One end of the central shaft body 221 is installed on the motor 23 and is driven by the motor 23. A grain distribution bearing is also installed on the central shaft body 221. The grain distribution bearing is located above the main bearing. The central circle of the grain distribution bearing is installed on the central shaft body 221, and the outer circle is installed on the connector 255. A motor 251 is installed beside the motor 23. The motor 251 is installed below the motor mounting plate 254. The output shaft end gear 2511 of the 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 motor 23. There is a convex groove above the connector 255. A channel 253 that can be engaged with the convex groove is provided below the grain distribution plate 24. Below the grain distribution plate 24 is the transmission gear 252. The transmission gear 252 meshes with the output shaft end gear 2511 of the motor 251 and is controlled by the motor 251 to rotate.

[0059] In some embodiments of the present application, the grain storage box 10 further includes a stirrer. The stirrer includes a central column body 121 and at least two blades 122. The blades 122 are fixedly connected to the central column body 121 in a radial manner. The central column body 121 is fixedly connected above the central shaft body 221 and the two are concentrically arranged. The stirrer can rotate around the motor 23.

[0060] Specifically, please refer to Figures 9 to 12As shown in the figure, a stirrer is installed at the bottom of the grain storage box 10. The stirrer is installed on the central shaft body 221 and fixed by nuts, and can rotate together with the central shaft body 221. The lower grain outlet 11 is located below the blades 122 of the stirrer. When the stirrer rotates, it can drive the pet food in the grain storage box 10 to fall from the lower grain outlet 11 to the grain distribution plate 24. At the same time, the pusher rotates to push the fallen pet food out from the grain distribution port 241 to the grain outlet 21, and then reaches the food tray 31 above the feeding box 30, so as to facilitate the pet to eat. The control box 20 is provided with a brush 27 above the pusher, and the brush 27 is installed below the grain storage box 10. When the pet food gets stuck when falling onto the pusher, the brush 27 can easily sweep the pet food down. The control box 20 can also be provided with two brushes 27, and the two brushes 27 are distributed in a V shape. Such a distribution can ensure that the brush 27 better covers the entire surface of the pusher. Then, no matter where the pet food falls, it can effectively clean the jamming, improve the fluidity of the pet food and the smoothness of the pet's eating.

[0061] In some embodiments of the present application, the stirrer includes three arc-shaped blades 122.

[0062] Specifically, the grain storage box 10 is installed above the control box 20 and connected by simple means such as buckles or threads. The stirrer and the pusher are driven by the motor 23 together. The design of the blade 122 is not limited to the structure of three arcs, and different shapes and numbers can also be selected according to actual needs, such as four, five or other polygonal structures, so as to better adapt to different types of pets and feeding needs.

[0063] In some embodiments of the present application, the grain storage box 10 further includes a partition 13. An arc structure 131 is provided at the bottom of the partition 13. The arc structure 131 is concentric with the central column body 121 and the arc structure 131 is separated from the blade 122. A slot 14 is provided on the inner wall of the grain storage box 10, and the partition 13 can be inserted into or withdrawn from the slot 14.

[0064] Specifically, the grain storage box 10 can be provided with one or more partitions 13. Users can insert or withdraw several partitions 13 according to actual needs, so as to put in various types of pet food and facilitate the mixed feeding of pets.

[0065] In some embodiments of the present application, a hollow structure 15 for placing a desiccant is further provided at the top of the grain storage box 10.

[0066] Specifically, the hollow structure 15 can be provided on the cover body above the grain storage box 10 to form a receiving cavity with the hollow structure 15. Placing a desiccant inside the receiving cavity can effectively absorb moisture, keep the pet food in the grain storage box 10 dry and fresh, and ensure that the pet can obtain a better taste and nutrition when eating.

[0067] The pet automatic feeder provided in this embodiment is a timing and quantitative automatic feeder suitable for multi-pet families, which can bring a more convenient and intelligent feeding experience to multi-pet families and is an innovative and practical pet product. To meet the feeding needs of multi-pet families, this pet automatic feeder is designed with three feeding ports (i.e., having three food trays 31), and 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 families. To meet the long-term feeding needs of multi-pet families, the storage box 10 of this pet automatic feeder is designed with a large-capacity storage bin, effectively avoiding the trouble of frequently replenishing pet food. At the same time, the storage box 10 is designed with a sealed structure, effectively preventing pet food from getting damp and deteriorating. Each component of this pet automatic feeder is designed to be easily disassembled and cleaned, facilitating users' daily maintenance and cleaning to ensure the dietary hygiene of pets.

[0068] The following details three common usage methods of this pet automatic feeder, including:

[0069] Before starting the pet automatic feeder, users can place pet food in the storage box 10 and set the feeding function.

[0070] Usage method 1: When the set feeding time arrives and there is no need to switch the grain outlet 21, the pet automatic feeder will start automatically, the motor 23 will start working, driving the stirrer and the grain pusher to rotate together. The pet food will fall from the grain outlet 11 to the grain distribution plate 24, and the rotating grain pusher in the grain distribution plate 24 will push the pet food out from the grain distribution port 241 to the grain outlet 21, and finally send the pet food to the food tray 31 above the feeding box 30 for the pet to eat conveniently.

[0071] Usage method 2: When the set feeding time arrives and it is necessary to switch the grain outlet 21, the motor 251 will start working, driving the grain distribution plate 24 to rotate to change the position of the grain distribution port 241, so as to communicate with different grain outlets 21. At the same time, the motor 23 will work together, driving the stirrer and the grain pusher to rotate synchronously to ensure that the grain pusher always covers above the grain distribution port 241 to prevent pet food from falling or insects from entering.

[0072] It should be noted that when the steps of usage method 2 are completed, the grain distribution port 241 reaches the specified position and communicates with a specific grain outlet 21. At this time, it is necessary to execute the steps of usage method 1 again to send the pet food to the specific food tray 31 above the feeding box 30.

[0073] Usage Mode 3: The user can set the amount of food received by each food tray 31 by modifying the program, specifically by allowing the user to set the number of portions of pet food that fall into the food tray 31. When the motor 23 starts, it will drive the agitator and the pusher to rotate together. The pet food that first falls from the food outlet 21 is recorded as 1 portion, and the pet food that falls again after the motor 23 continues to run is recorded as 2 portions, and so on. The user can set different amounts of food received for the three food trays 31, that is, the number of portions of pet food that fall, to meet the dietary needs of different pets.

[0074] For a single-pet family, only one food tray 31 needs to be set to receive one portion of pet food, and the other food trays 31 do not receive food. At this time, the pet automatic feeder only needs to repeat the steps of Usage Mode 1 to achieve automatic feeding for a single pet.

[0075] For a multi-pet family, such as a family with three pets, the corresponding positions of the three food trays 31 can be defined as No. 1, No. 2, and No. 3. Due to the different eating habits of pets, the three food trays 31 are respectively set to receive 1 portion of pet food, 2 portions of pet food, and 3 portions of pet food. Then, first, the pet automatic feeder executes the steps of Usage Mode 2 once, converts the food distribution port 241 to the position connected to the food outlet 21 corresponding to the No. 1 food tray, and then executes the steps of Usage Mode 1 once; then, the pet automatic feeder executes the steps of Usage Mode 2 once, converts the food distribution port 241 to the position connected to the food outlet 21 corresponding to the No. 2 food tray, and then executes the steps of Usage Mode 1 twice; finally, the pet automatic feeder executes the steps of Usage Mode 2 once, converts the food distribution port 241 to the position connected to the food outlet 21 corresponding to the No. 3 food tray, and then executes the steps of Usage Mode 1 three times. In this way, the purpose of the three food trays 31 receiving 1 portion, 2 portions, and 3 portions of pet food respectively can be achieved. Subsequently, the pet automatic feeder only needs to repeat the above steps to achieve automatic feeding for multi-pets.

[0076] The pet automatic feeder provided in this embodiment is optimized and designed for the special needs of multi-pet families, and has the advantages of three feeding ports, intelligent control, a large-capacity storage granary, easy cleaning, and pet recognition. This product has broad application prospects in the market. It can not only meet the feeding needs of multi-pet families, but also improve the quality of life of pet owners and reduce their daily burden. At the same time, with the continuous development of the pet economy, the market demand for this product will also continue to grow.
