Description

Technical Field

[0001] The present invention relates to the technical field of pet supplies, and in particular to an automatic pet feeding device. Background Art

[0002] Currently, pet feeders on the market mainly rotate a plate to open a food storage bin, thereby allowing pet food to flow out of the bin to achieve the purpose of feeding.

[0003] For example, the utility model patent with publication number CN214853533U, entitled "A New Automatic Feeder", see Figure 1 and Figure 2 This patent includes a pair of rotating plates driven by a controller. During the rotation of the rotating plates 6, one of the rotating plates 6 squeezes the return spring 11, opening the lower feeding port 7, and the pet food in the food storage box 2 flows out through the lower feeding port 7. When the rotating plate 6 reaches the side of the lower feeding port 7 close to the sliding groove 8, the return spring 11 pushes the blocking plate 9 to close the lower feeding port 7. However, in this technology, the opening and closing of the lower feeding port 7 requires the rotation of the blocking plate 9 in the lower feeding port 7. When the pet food flows out of the lower feeding port 7, the lower feeding port 7 is filled with pet food, and the blocking plate 9 needs to overcome the resistance of the pet food and close the entire lower feeding port 7. When the weight and size of the pet food are large, there is a phenomenon that the food is stuck and cannot be completely closed.

[0004] See Figure 3 In another utility model patent with publication number CN204796445U and titled "A feed hopper for an intelligent pet feeder", a feed hopper bottom plate 13 is provided at the bottom of the feed hopper 1, and a feed outlet 10 is provided on the feed hopper bottom plate 13. The lower end of the rotating shaft 2 passes through the feed outlet baffle 12, and the upper end of the rotating shaft 2 passes through the feed hopper bottom plate 13 and is connected to the rotating cover 7. Upper paddles 4 are provided on the left and right sides of the rotating cover 7. When the upper paddles rotate, the pet food in the feed hopper 1 is pushed out of the feed outlet 10. In this technical solution, when the upper paddles rotate, the pet food in the feed hopper 1 is pushed out of the feed outlet 10. When the shaft 2 and the rotary cover 7 rotate, they rotate together in the silo 1, but it is still impossible to ensure that the discharge port 10 is fully filled and the pet food in the silo 1 is not stuck between the edge of the discharge port 10 and the upper paddle 4, and it is impossible to achieve complete anti-blocking. At the same time, the discharge port 10 is always open, and the pet food will continue to flow out of the silo 1 until there is no pet food in the silo 1. In this case, it is impossible to achieve quantitative feeding, and it is also impossible to ensure that the pet food in the silo 1 will not be contaminated by water vapor and bacteria from outside the discharge port 10, resulting in mold, etc., which affects the safety of the pets.

[0005] See Figure 4In another invention patent with publication number CN106376478A and titled "A Pet Feeder and Pet Feeding System", a first discharge port is provided at the lower end of the storage barrel, and the second motor first pushes the pet food from the first discharge port into the feeding wheel, and then the feeding wheel outputs the entered pet food from the second discharge port on the feeding wheel to the guide trough until it enters the feeding bowl. In this patent, it is first necessary to set up multiple motors and an intermediate component feeding wheel. The pet food first enters the feeding wheel and is then pushed to the external feeding bowl. The structure of the present invention is complex and the cost is high. Furthermore, when the pet food enters the feeding wheel, the rotating paddle driven by the second motor may also cause food jams. In addition, the patent of this invention does not disclose the closed structure from the feeding bowl to the guide trough, feeding wheel and storage barrel, and cannot guarantee that the external environment will not contaminate the pet food in the storage barrel and affect the health of the pet. Summary of the Invention

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0047] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0048] Please refer to Figure 4-Figure 8 As shown, the present invention discloses an automatic pet feeding device, which includes a grain storage bin 10, a grain pushing component 20 and a grain pushing bin 30, wherein the grain pushing component 20 is slidably arranged between the grain storage bin 10 and the grain pushing bin 30 to open and close the grain storage bin 10, and push the pet food that flows into the grain pushing bin 30 when the grain storage bin 10 is opened out of the grain pushing bin 30, and then close the grain storage bin 10 and the grain pushing bin 30 again after pushing out.

[0049] Specifically, the lower portion of the grain storage bin 10 is provided with a grain leakage port 11 , and the pet food stored in the grain storage bin 10 flows into the grain pushing bin 30 through the grain leakage port 11 .

[0050] The grain pushing bin 30 is disposed below the grain storage bin 10 and includes a grain outlet 31 . The grain pushing bin 10 is in communication with the grain outlet 11 . In this embodiment, a portion of the grain pushing member 20 extends into the grain pushing bin 30 . The grain pushing member 20 disposed within the grain pushing bin 30 is used to push the pet food into the grain pushing bin 30 .

[0051] See Figure 6 and Figure 7 The grain outlet 31 includes a first opening 311 arranged horizontally and a second opening 312 arranged vertically, and the first opening 311 and the second opening 312 are in a “┓” shape.

[0052] In this embodiment, the grain outlet 31 is set to be in a "┓" shape. On the one hand, it can ensure that the grain in the grain pushing bin 30 flows out quickly and at the maximum flow rate to prevent the grain pushing bin 30 from being blocked; on the other hand, the grain outlet 31 can cooperate with the grain pushing component 20 to achieve complete closure.

[0053] Specifically, the grain pushing member 20 includes a flat plate portion 21 and a pushing plate portion 22, wherein the flat plate portion 21 includes a front end 211 and a rear end 212, and the front end 211 is closer to the grain outlet 31. One end of the pushing plate portion 22 is connected to the flat plate portion 21, and extends from the flat plate portion 21 into the grain pushing bin 30. The length of the pushing plate portion 22 is adapted to the depth of the grain pushing bin 30, that is, the bottom of the pushing plate portion 22 is against the grain pushing bin 30, and the length of the pushing plate portion 22 is also consistent with the height of the grain outlet 31. In particular, the connection position between the pushing plate portion 22 and the flat plate portion 21 is located near the middle of the flat plate portion 21, and the pushing plate portion 22 and the flat plate portion 21 together form a T-shaped structure; wherein, the grain pushing member 20 is slidably connected between the grain storage bin 10 and the grain pushing bin 30, and the sliding direction is the same as or opposite to the direction of pet food outflow from the grain pushing bin 30.

[0054] The edge of the first opening 311 is flush with the flat plate portion 21 , and the second opening 312 is connected to the first opening 311 . The length of the first opening 311 is the same as that of the front end 211 , and the height of the second opening 312 is the same as that of the push plate portion 22 .

[0055] When the grain pusher 20 moves away from the grain outlet 31, the flat plate 21 approaches the front end of the grain outlet 31, connecting the grain storage bin 10 and the grain pusher 30. The grain outlet 11 opens, and the grain outlet 31 also opens vertically and horizontally. When the grain pusher 20 connects the grain storage bin 10 and the grain pusher 30, the pet food in the grain storage bin 10 can fall from the grain outlet 11 into the grain pusher 30 under the action of its own gravity.

[0056] When the grain pushing member 20 moves away from the grain outlet 31 , the front end 211 opens the first opening 311 , and the pushing plate 22 opens the second opening 312 simultaneously. As the movement continues, the front end 211 gradually closes the grain leakage outlet 11 .

[0057] Specifically, as the food pusher 20 moves toward the grain outlet 31, the flat plate 21 approaches the front end of the grain outlet 31, closing the grain storage bin 10 and the grain pusher 30. This seals the grain outlet 11, and the grain outlet 31 gradually closes vertically and horizontally. Simultaneously, the pet food within the grain pusher 30 flows out of the grain outlet 31 under the action of the moving pusher plate 22, effectively pushing the pet food.

[0058] That is to say, when the food pushing component 20 moves to the farthest end on one side of the food outlet 31, the front end 211 of the flat plate portion 21 close to the food outlet 31 is located at the first opening 311, closing the first opening 311, and the rear end 212 of the flat plate portion 21 away from the food outlet 31 closes the food leakage port 11, and the pushing plate portion 22 also closes the second opening 312 after pushing all the pet food in the food storage bin 10 out of the food outlet 31.

[0059] The state at this time is that the grain leakage port 11 of the grain storage bin 10 and the first opening 311 of the grain outlet 31 are simultaneously closed by the flat plate portion 21 of the grain pushing member 20, and the second opening 312 of the grain outlet 31 is closed by the pushing plate portion 22 used to push the grain, thereby realizing double closure of the grain leakage port 11 and the grain outlet 31, as well as full closure of the grain outlet 31 in the horizontal and vertical directions.

[0060] In this embodiment, the grain pushing component 20 is arranged between the grain storage bin 10 and the grain pushing bin 30 in a sliding manner. In this way, the size requirements of the grain pushing component 20 are relatively low. For example, grain pushing components 20 of different lengths can be installed. It is only necessary to control the moving stroke of the grain pushing component 20 to achieve the purpose of opening and closing the grain leakage port and the grain discharge port, which is more applicable.

[0061] In this embodiment, the structural design is ingenious. The grain outlet 31 is fully closed in both directions by pushing the push plate portion 22 and the flat plate portion 21 of the pet food in the grain pushing bin 30, and the grain leakage port 11 of the grain storage bin 10 is sealed by the flat plate portion 21 at the same time. Compared with the traditional method of sealing only the grain storage bin 10, this double-sealing method can effectively prevent external insects and ants from entering the grain pushing bin 30 and the grain storage bin 10 from the grain outlet 31 and contaminating the pet food, thereby ensuring that the pet food is kept for a long time and is not damp. In addition, the present application can control the actual conduction size of the grain leakage port 11 by controlling the stroke of the grain pushing member 20, so as to facilitate the entry of pet food of different sizes from the grain leakage port 11 into the grain pushing bin 30, and further control the conduction time to achieve the purpose of quantitative delivery.

[0062] In an embodiment of the present invention, the push plate portion 22 also plays a supporting role during the movement of the food pushing member 20, and is used to support the pet food located above the push plate portion 22 to prevent the flat plate portion 21 from deforming and affecting the pushing effect.

[0063] Furthermore, the food outlet 31 of the present invention adopts a two-dimensional opening method of vertical and horizontal, which can ensure the outflow of pet food to the maximum extent and at the maximum flow rate, and there is no problem of blockage caused by excessive pushing speed.

[0064] In this embodiment, the first opening 311 is coplanar with the flat plate portion 21, that is, the height setting of the first opening 311 can just ensure that the front end of the flat plate portion 21 close to the grain outlet 31 is completely against the upper end surface of the first opening 311 when it moves to the farthest end on one side of the grain outlet 31, thereby ensuring the sealing effect.

[0065] When adding pet food to the automatic pet feeding device of the present invention, the food pusher 20 moves to the farthest end near the food outlet 31, completely sealing the food outlet 11 and the food outlet 31. After the pet food is added to the food storage bin 10, the food pusher 20 moves away from the food outlet 31, gradually opening the food outlet 11 and the food outlet 31, allowing the pet food to flow from the food storage bin 10 to the food outlet 31. When the amount of pet food added reaches a predetermined amount, the food pusher 20 moves toward the food outlet 31. During this movement, the flat plate 21 gradually seals the food outlet 11, while the pusher 22 simultaneously pushes the remaining pet food in the food pushing bin 30 out of the food outlet 31. As the grain pushing member 20 moves, the grain leakage port 11 is completely closed. After the pushing plate portion 22 completely pushes out the pet food in the grain pushing bin 30, the pushing plate portion 22 has moved to the second opening 312 of the grain outlet 31, thereby closing the second opening 312, and the front end of the flat plate portion 21 close to the grain outlet 31 is also located in the first opening 311, abutting against the upper end surface of the first opening 311. That is to say, after the grain pushing member 20 pushes out all the pet food in the grain pushing bin 30, it also closes the grain outlet 31 from two directions.

[0066] When the pet food is put in next time, the food pushing member 20 moves away from the food outlet 31 again to complete the putting in, and the above actions are repeated.

[0067] In an optional embodiment of the present invention, the automatic feeding device for pets further includes a buffer sheet 40, which is disposed on the side of the grain leakage port 11 close to the grain outlet 31. The buffer sheet 40 is disposed vertically and is in the shape of an elongated strip. The grain leakage port 11 further includes a third opening 111 and a fourth opening 112 that are connected to each other. The fourth opening 112 is disposed above the third opening 111 and is connected to the grain pushing bin 30. The cross-section of the grain leakage port 11 is L-shaped. The third opening 111 is parallel to the plane where the flat plate portion 21 is located. The buffer sheet 40 is installed at the fourth opening 112. A groove portion 12 is disposed near the fourth opening 112 of the grain storage bin 10. One end of the buffer sheet 40 is inserted into the groove portion 12 to block the fourth opening 112.

[0068] In this embodiment, when the food leakage port 11 and the food outlet 31 are opened, the pet food in the food storage bin 10 flows out from the food leakage port 11 and the food outlet 31. A portion of the pet food that flows out contacts the buffer sheet 40 during the flow. The buffer sheet 40 acts as a barrier to prevent the pet food from flowing directly out of the food leakage port 11 through the food outlet 31 at a larger angle and direction, thereby causing the pet food flowing out of the food outlet 31 to spread out into a larger space and be difficult to gather, and cannot be effectively contained in the feeding container.

[0069] Furthermore, the buffer sheet 40 includes an inserting portion 41 and an extending portion 42 connected to each other. The thickness of the inserting portion 41 is greater than that of the extending portion 42 , and the inserting portion 41 is fixed in the groove portion 12 .

[0070] In this embodiment, the bottom end of the extended portion 42 in the buffer sheet 40 is aligned with the edge height of the vertical portion 112 in the grain leakage opening 11. On the one hand, this can push the flowing pet food during the movement of the grain pushing member 20, preventing the pet food from flowing out of the gap between the grain pushing member 20 and the buffer sheet 40. At the same time, the edge of the fourth opening 112 seals the grain leakage opening 11, ensuring the smooth movement of the grain pushing member 20 without obstructing it. On the other hand, the arrangement is inserted, rather than being separately arranged outside the grain leakage opening 11 toward the grain pushing member 20, so that the size of the entire grain storage bin 10 can be kept smaller without increasing the height of the grain storage bin 20.

[0071] In this embodiment, the long strip of buffer sheet 40 serves to block some pet food from flowing directly out of the food leakage port 11 and the food outlet 31. At the same time, a thicker insert portion is fixed in the groove to ensure the fixing strength of the buffer sheet 40 and improve the impact resistance of the buffer sheet 40 from the flowing pet food.

[0072] In another embodiment of the present invention, a grain stirring piece 90 is provided in the grain storage bin 10. When the grain stirring piece 90 rotates, the pet food stored in the grain storage bin 10 flows out through the grain leakage port as it is stirred.

[0073] In this embodiment, the pet food flows out of the food outlet 11 faster under the action of the food stirring piece 90. At this time, the blocking effect of the buffer piece 40 is more obvious, which can ensure that the pet food flowing out of the food outlet 31 is relatively concentrated. The thicker insert is fixed in the groove, which further ensures the fixing strength of the buffer piece and can adapt to the faster flow of pet food.

[0074] In some preferred embodiments, the buffer sheet 40 is made of a soft material. The buffer sheet 40 made of a soft material can play a buffering role when the pet food flows from the food outlet 11, and can more effectively prevent the pet food from flowing directly out of the food outlet 31 in a large area, and can withstand greater impact from the pet food.

[0075] The buffer sheet made of soft material in the present invention has another more important beneficial effect, that is, it can prevent the grain pushing member 20 and the buffer sheet 40 from being blocked when the grain pushing member 20 moves toward the grain outlet 31 .

[0076] Specifically, one state is that in the process of the food pushing member 20 moving toward the food outlet 31, as the distance between the tip position of the flat plate portion 21 in the food pushing member 20 and the buffer plate 40 gradually decreases as it approaches the food outlet 31, the pet food flowing out from the extended portion 42 of the buffer plate 40 and the tip position of the flat plate portion 21 hits the extended portion 42. Under the action of its own elasticity, the extended portion 42 pushes the impacted part of the pet food to move slightly in the opposite direction of the pet food flow, that is, toward the grain storage bin 10. At this time, the pet food moving toward the inside of the grain storage bin 10 and the pet food flowing out of the grain storage bin 10 interact with each other, which is conducive to making the pet food flowing out of the food leakage port 11 in a loose state, thereby preventing blockage; at the same time, the part of the pet food acted upon by the buffer plate 40 will be bounced to the upper surface of the flat plate portion 21, that is, inside the grain storage bin 10. These pet foods that are difficult to directly pass through the buffer plate 40 will not gather in a smaller space, thereby avoiding the occurrence of food jams.

[0077] Another most important state is that when the food pushing member 20 moves toward the food outlet 31, as the distance between the tip position of the flat plate portion 21 in the food pushing member 20 and the buffer plate 40 gradually decreases when it approaches the food outlet 31, some larger pet food is stuck in the area between the tip position and the buffer plate 40. When the food pushing member 20 continues to move, the buffer plate 40 produces elastic deformation toward the side of the food outlet 31. At this time, the buffer plate 40 acts on the larger pet food, bounces the larger pet food away, and ensures that the food pushing member 20 can move further to prevent blockage.

[0078] In a preferred embodiment of the present invention, the end of the food pusher 20 facing the food outlet 31 is further provided with an inclined surface A facing the food pusher hopper 30. When larger pet food is stuck between the buffer sheet 40 and the tip of the food pusher 20 near the food outlet 31, the buffer sheet 40 can push the pet food along the inclined surface into the food pusher hopper 30.

[0079] See Figure 9 In an optional embodiment, a guide groove B is provided on the side wall of the grain pushing bin 30, and the width of the guide groove B is adapted to the width of the flat plate portion 21, and the flat plate portion 21 is placed in the guide groove B. The grain pushing bin 30 is provided at one end of the bottom wall of the guide groove B, and the grain outlet 31 is provided at one end of the grain pushing bin 30. In an optional embodiment, a flat plate member 50 is further provided on the grain pushing member 20, and the flat plate member 50 is mounted on the bottom wall of the lower shell 52, and the lower surface of the flat plate member 50 abuts against the grain pushing member 20, and the upper side surface of the flat plate member 50 abuts against the bottom of the horizontal opening of the grain leakage port 11. With this structure, the grain pushing member 20 is limited in the vertical direction, so that the grain pushing member 20 moves horizontally in the guide groove B.

[0080] In an optional embodiment, the automatic pet feeding device of the present application further includes a grain bowl 60, and the grain bowl 60 is disposed below the grain outlet 31, so that pet food can fall from the grain outlet 31 into the grain bowl 60 for consumption by the pet. In the present application, the distance between the grain bowl and the grain outlet is large, thereby avoiding the occurrence of undesirable situations such as grain blockage.

[0081] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
