Description

Technical Field

[0001] This utility model belongs to the field of feeding technology, and more specifically, relates to an intelligent feeder. Background Technology

[0002] Feeders offer many conveniences for pet feeding, such as allowing pets to be fed at set times and in set quantities when the owner is away, which helps maintain the pet's regular eating habits.

[0003] To reduce the frequency of feeding, some feeders are equipped with food storage bins, allowing for larger batches of food to be stored and fed to pets multiple times. However, due to the overly simple internal structure of these food storage bins, food can easily become trapped at the bottom opening during dispensing, causing blockages and affecting the feeder's dispensing process. Utility Model Content

[0004] In view of this, the present invention provides an intelligent feeder to solve the technical problem of feeders being prone to clogging.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model embodiment provides an intelligent feeder, comprising: a food storage bin with a first opening on its bottom wall; a food dispensing bin disposed below the food storage bin with a second opening at its bottom; and a rotating mechanism, at least partially disposed within the food dispensing bin, for dispensing food from the food storage bin into the food dispensing bin through the first opening and dispensing food from the food dispensing bin out through the second opening; wherein the food storage bin has a conical first sidewall formed inside, the diameter of the top end of the first sidewall being larger than the diameter of the bottom end, and the first sidewall having at least one annular buffer protrusion protruding toward the central axis of the first sidewall.

[0007] In some embodiments, the buffer protrusion has an upper edge and a lower edge connecting the first sidewall, the perimeter of the upper edge being greater than the perimeter of the lower edge.

[0008] In some embodiments, the height of the buffer protrusion exhibits both a gradually increasing and a gradually decreasing trend in the radial direction.

[0009] In some embodiments, multiple buffer protrusions are arranged sequentially in the vertical direction.

[0010] In some embodiments, the grain storage hopper also has a cylindrical second sidewall formed inside, with the bottom end of the second sidewall connected to the top end of the first sidewall.

[0011] In some embodiments, the first sidewall, the second sidewall, and the buffer protrusion are integrally formed.

[0012] In some embodiments, the system further includes: an outlet channel, which is inclined relative to the central axis of the first sidewall, the top end of the outlet channel communicating with the second opening; and a food bowl, which is disposed at the bottom end of the outlet channel.

[0013] In some embodiments, a gravity detection device is provided at the bottom of the food bowl to detect the weight of the food inside the food bowl.

[0014] In some embodiments, the first sidewall is provided with at least one set of infrared detection devices to determine whether there is enough food in the grain storage bin.

[0015] The feeder provided in this embodiment includes a grain storage bin, a grain dispensing bin, and a rotating mechanism. The bottom wall of the grain storage bin has a first opening. The grain dispensing bin is located below the grain storage bin, and its bottom has a second opening. The rotating mechanism is at least partially located inside the grain dispensing bin, allowing food from the grain storage bin to flow into the dispensing bin through the first opening and to flow out of the dispensing bin through the second opening. The grain storage bin has a conical first sidewall, the diameter of the top of the first sidewall being larger than the diameter of the bottom. The first sidewall has at least one annular buffer protrusion protruding towards its central axis. By shaping the first sidewall of the grain storage bin into an inverted cone shape and providing a buffer protrusion, this embodiment reduces the flow rate of food within the grain storage bin during storage, thereby reducing the risk of food clogging the first opening.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0027] This utility model provides an intelligent feeder. The feeder is suitable for various feeding scenarios. For example, it can be used to feed pets, automatically dispensing food to cats, dogs, hamsters, and other pets at set times and in measured quantities, making it convenient for pets to eat when their owners are not home. Alternatively, it can be used to raise poultry such as chickens and ducks, enabling large-scale, automated feed dispensing.

[0028] like Figure 1 and Figure 2 As shown, the feeder includes a food storage bin 1, a food dispensing bin 2, and a rotating mechanism 3. The food storage bin 1 can be used to store pet food, pelleted fish food, and other special pelleted food. A first opening 11 is provided on the bottom wall of the food storage bin 1, and the food dispensing bin 2 is located below the food storage bin 1; thus, food in the food storage bin 1 flows into the food dispensing bin 2 through the first opening 11 under its own weight. The rotating mechanism 3 is at least partially located inside the food dispensing bin 2; a second opening 21 is provided at the bottom of the food dispensing bin 2, and an outlet channel 4 and a food bowl 5 are provided below the second opening 21; thus, food in the food dispensing bin 2 flows out through the second opening 21 under the combined action of its own weight and the rotating mechanism 3.

[0029] like Figure 2 As shown, the interior of the grain storage bin 1 has a conical first sidewall 12. The diameter of the top end of the first sidewall 12 is larger than the diameter of the bottom end, meaning the first sidewall 12 is an inverted cone with the larger end facing up and the smaller end facing down. This inverted cone provides support for the food inside the grain storage bin 1, thereby slowing down the rate at which the food slides down. It can be understood that if the first sidewall 12 were a vertical sidewall, the food inside the grain storage bin 1 could fall freely under gravity, causing the food to flow too quickly and rapidly accumulate at the first opening 11, resulting in a blockage. Therefore, the inverted cone shape of the first sidewall 12 slows down the flow of food, thus reducing the risk of blockage at the first opening 11.

[0030] like Figure 2 As shown, the first sidewall 12 is provided with at least one annular buffer protrusion 13, which protrudes towards the central axis of the first sidewall 12. The central axis of the first sidewall 12 is parallel to the extension direction of the grain dispensing hopper 2. Under normal operating conditions, the central axis of the first sidewall 12 is vertical, indicated by the dashed line a in the figure. During grain storage, the food inside the grain storage hopper 1 flows. Due to the buffer protrusion 13, the flow rate of the food inside the grain storage hopper 1 slows down when it encounters the buffer protrusion 13, and the food flows slowly towards the first opening 11 instead of quickly clogging the first opening 11, thereby reducing the risk of food clogging the first opening 11.

[0031] The feeder provided in this embodiment includes a grain storage bin 1, a grain dispensing bin 2, and a rotating mechanism 3. The bottom wall of the grain storage bin 1 has a first opening 11. The grain dispensing bin 2 is located below the grain storage bin 1, and its bottom has a second opening 21. The rotating mechanism 3 is at least partially located inside the grain dispensing bin 2, allowing food from the grain storage bin 1 to flow into the grain dispensing bin 2 through the first opening 11 and to flow out of the grain dispensing bin 2 through the second opening 21. The grain storage bin 1 has a conical first sidewall 12 inside, with the diameter of the top end of the first sidewall 12 being larger than the diameter of the bottom end. The first sidewall 12 has at least one annular buffer protrusion 13 protruding towards the central axis of the first sidewall 12. This embodiment of the invention reduces the flow speed of food in the grain storage bin 1 during the storage process by setting the first sidewall 12 of the grain storage bin 1 in an inverted cone shape and providing the buffer protrusion 13, thereby reducing the risk of food clogging the first opening 11.

[0032] In some embodiments, as Figure 2 As shown, the buffer protrusion 13 has an upper edge 131 and a lower edge 132 connecting the first sidewall 12. The circumference of the upper edge 131 is greater than the circumference of the lower edge 132. Therefore, in the radial direction, the lower edge 132 protrudes relative to the upper edge 131, which facilitates the flow of food in the grain storage bin 1 from the upper edge 131 to the lower edge 132. It can be understood that if the circumference of the lower edge 132 is greater than the circumference of the upper edge 131, then in the radial direction, the lower edge 132 is concave relative to the upper edge 131. This would prevent food in the grain storage bin 1 from reaching the lower edge 132 from the upper edge 131, creating a gap near the lower edge 132, which is detrimental to the space utilization inside the grain storage bin 1.

[0033] This embodiment of the invention allows for full utilization of the internal space of the grain storage bin 1 by controlling the perimeter of the upper edge 131 and lower edge 132 of the buffer protrusion 13.

[0034] In some embodiments, as Figure 2 As shown, the height of the buffer protrusion 13 exhibits both a gradually increasing and a gradually decreasing trend in the radial direction. The height of the buffer protrusion 13 is represented by H in the figure; there are multiple radial directions, which can be understood as directions perpendicular to the central axis a, and are exemplarily represented by the dashed line b in the figure.

[0035] This embodiment of the utility model sets the radial structure of the buffer protrusion 13 to gradually increase and gradually decrease, making the buffer protrusion 13 an irregular shape. As a result, the speed at which the food in the grain storage bin 1 flows through the buffer protrusion 13 is different, which is conducive to the food flowing into the first opening 11 of the grain storage bin 1 in an alternating manner, thereby helping to reduce the risk of the first opening 11 being blocked.

[0036] In some embodiments, multiple buffer protrusions 13 are sequentially arranged in the vertical direction. Figure 2 The example shown uses only one buffer protrusion 13. The vertical direction can be understood as the up-down direction of the feeder in normal use, which is parallel to the central axis a of the first side wall 12.

[0037] This embodiment of the utility model, by setting multiple buffer protrusions 13, can increase the number of buffering times of the food in the grain storage tank 1, thereby further reducing the flow rate of the food when it is discharged, that is, further reducing the risk of the first opening 11 being blocked.

[0038] In some embodiments, as Figure 2 As shown, the interior of the grain storage bin 1 also has a cylindrical second sidewall 14, the bottom of which connects to the top of the first sidewall 12. In other words, the internal space of the grain storage bin 1 includes a cylindrical space at the top and a conical space at the bottom. It can be understood that the cylindrical storage space can store more food than the conical storage space.

[0039] This embodiment of the invention increases the storage capacity of the grain storage bin 1 by adding a cylindrical storage space, which is conducive to storing more food.

[0040] In some embodiments, as Figure 2 As shown, the first sidewall 12, the second sidewall 14, and the buffer protrusion 13 are integrally formed, and the surface of the buffer protrusion 13 smoothly transitions to the first sidewall 12 and / or the second sidewall 14. In this way, the risk of food getting stuck on the surfaces of the first sidewall 12, the second sidewall 14, and the buffer protrusion 13 can be reduced.

[0041] In some embodiments, as Figure 2 and Figure 3 As shown, an outlet channel 4 and a feeding bowl 5 are provided below the second opening 21. Specifically, the outlet channel 4 is inclined relative to the central axis a of the first side wall 12. The top of the outlet channel 4 is connected to the second opening 21, and the feeding bowl 5 is provided at the bottom of the outlet channel 4 so that the food in the food container 2 can flow out of the second opening 21 under its own weight and slide into the feeding bowl 5 along the outlet channel 4.

[0042] like Figure 2 and Figure 4As shown, the feeder also includes a rotating mechanism 3. The rotating mechanism 3 includes a first impeller 31 disposed within the grain distribution bin 2, which divides the internal space of the grain distribution bin 2 into multiple sub-spaces 22. The multiple sub-spaces 22 can be understood as having a number greater than or equal to two. Furthermore, the multiple sub-spaces 22 are arranged around the axis of the first impeller 31. During the rotation of the first impeller 31, each sub-space 22 alternately connects to the first opening 11 and alternately connects to the second opening 21; wherein, the "sub-space 22 connected to the first opening 11" and the "sub-space 22 connected to the second opening 21" are two different sub-spaces 22; that is, a sub-space 22 cannot simultaneously connect to both the first opening 11 and the second opening 21. Thus, during the rotation of the first impeller 31, food in the grain storage bin 1 flows sequentially from the first opening 11 into each sub-space 22, and food in each sub-space 22 flows sequentially out from the second opening 21, thereby achieving continuous feeding.

[0043] To stop the feeder from dispensing food, simply stop the rotation of the rotating mechanism 3. It can be understood that if the rotating mechanism 3 stops rotating, the subspace 22 connected to the first opening 11 will be filled with food, while the subspace 22 connected to the second opening 21 will be emptied, thus stopping the feeding process.

[0044] This embodiment of the invention incorporates a rotatable first impeller 31 within the food distribution bin 2. Two adjacent impellers of the first impeller 31 form sub-spaces 22. As the impellers rotate, food from the food storage bin 1 flows sequentially into each sub-space 22 through the first opening 11, and food from each sub-space 22 flows sequentially out through the second opening 21, thus achieving feeding. In other words, the first impeller 31 not only divides the internal space of the food distribution bin 2 but also extends the movement path of the food within it, reducing the risk of food blockage. Compared to other feeders that use valves to open and close to control feeding, this invention achieves feeding and stopping by having multiple sub-spaces 22 flow sequentially through the first and second openings 11 and 21, reducing the risk of food blockage in the food distribution bin 2. Furthermore, the multiple sub-spaces 22 allow for convenient control of the amount of food fed each time, facilitating a balanced diet for pets or other animals.

[0045] In some embodiments, as Figure 2 and Figure 4 As shown, the rotating mechanism 3 also includes a motor 32 and a limit switch 33. The motor 32 is located on the outside of the grain dispensing bin 2 to drive the first impeller 31 to rotate; the limit switch 33 is located near the motor 32 to detect the number of rotations of the output shaft of the motor 32.

[0046] The limit switch 33 can be exemplarily composed of a contact system, a spring, etc. The working principle of the limit switch 33 is as follows: when a component fixedly connected to the rotating shaft of the first impeller 31 presses against the spring of the limit switch 33, the internal circuit of the contact system is closed; when the moving component moves away, the contact system resets under the action of the spring, and the internal circuit of the contact system is opened; thus, the circuit is controlled by mechanical collision. Correspondingly, the number of collisions of the limit switch 33 equals the number of circuit openings and closings, thereby detecting the number of rotations of the output shaft of the motor 32, further detecting the number of rotations of the first impeller 31, and thus determining the number of subspaces 22 connected to the second opening 21 during the rotation of the first impeller 31. In this way, the amount of food fed can be determined.

[0047] This embodiment of the invention uses a limit switch 33 to facilitate control over the number of rotations of the subspace 22 within the food distribution bin 2, thereby facilitating control over the amount of food fed.

[0048] In some embodiments, as Figure 2 and Figure 4 As shown, the rotating mechanism 3 also includes a reduction gearbox 34. Connected to the output shaft of the motor 32, the outer wall of the reduction gearbox 34 is provided with a plurality of contact protrusions 35 in the circumferential direction for the limit switch 33 to contact; wherein, in the extension direction of the output shaft of the motor 32, the projection of each contact protrusion 35 overlaps with the projection of each subspace 22, that is, the number and position of the contact protrusions 35 correspond to the number and position of the subspaces 22 respectively.

[0049] The following explanation uses a scenario where there are four subspaces 22, arranged sequentially around axis a: the first subspace 22, the second subspace 22, the third subspace 22, and the fourth subspace 22. When the touch protrusion 35 touches the limit switch 33, the first subspace 22 connects to the first opening 11, and the third subspace 22 connects to the second opening 21. The first subspace 22 gradually fills up, and the third subspace 22 gradually empties, thus allowing feeding. If the motor 32 stops driving, the first subspace 22 remains connected to the first opening 11, and the third subspace 22 remains empty, thus ceasing feeding. Therefore, the position of the subspace 22 relative to the first opening 11 and the second opening 21 can be easily determined, facilitating the switching between feeding and non-feeding states.

[0050] This embodiment of the utility model, through the corresponding setting of the touch protrusion 35 and the subspace 22, makes it easy to know the position information of the subspace 22, which is beneficial to the opening and closing of the grain distribution bin 2.

[0051] In some embodiments, as Figure 2 and Figure 4As shown, the first impeller 31 includes a first shaft 311 and a plurality of first blades 312. The first shaft 311 is fixedly connected to the output shaft of the motor 32 or the gearbox 34; the plurality of first blades 312 are arranged around the outer wall of the first shaft 311; wherein, two adjacent first blades 312 and the inner wall of the grain distribution bin 2 form a subspace 22. Thus, the first blades 312 and the subspace 22 rotate under the drive of the motor 32.

[0052] Specifically, the first blade 312 is evenly arranged around the first wheel shaft 311, and the extension direction of the surface of the first blade 312 is parallel or approximately parallel to the axial direction of the first wheel shaft 311. In the normal use state of the feeder, the first blade 312 is vertically set.

[0053] This embodiment of the invention uses a motor 32 to drive the rotation of the first blade 312 and the sub-space 22, thereby achieving uniform division of the internal space of the grain distribution bin 2, so that the size of each sub-space 22 is consistent, so as to control the fraction and total amount of food flowing out.

[0054] In some embodiments, as Figure 3 and Figure 4 As shown, the first blade 312 is spaced apart from the top wall of the grain distribution bin 2. A combing plate 23 is provided on the top wall of the grain distribution bin 2, and the height of the combing plate 23 is less than or equal to the distance between the blades. One combing plate 23 may be provided around the first wheel shaft 311, or multiple combing plates may be provided.

[0055] During the rotation of the first impeller 31, if the height of the food in a subspace 22 is higher than the height of the first blade 312, the combing plate 23 will push the food that is higher than the height of the first blade 312 into other subspaces 22. This makes the height of the food in each subspace 22 equal to that of the first blade 312, so that the amount of food in each subspace 22 is consistent, which is conducive to controlling the amount of food flowing out.

[0056] Furthermore, due to the arrangement of the combing plate 23, there is a gap between the food in each sub-space 22 and the top wall of the grain distribution bin 2, which facilitates the rotation of the first blade 312 and reduces the risk of food getting stuck between the first impeller 31 and the grain distribution bin 2.

[0057] In some embodiments, as Figure 3 and Figure 4 As shown, at least one of the first blade 312 and the carding plate 23 is made of soft rubber, including at least three cases: first, only the first blade 312 is made of soft rubber; second, only the carding plate 23 is made of soft rubber; third, both the first blade 312 and the carding plate 23 are made of soft rubber. The soft rubber can be, exemplarily, thermoplastic polyurethane rubber (TPU).

[0058] This embodiment of the invention uses at least one of the first blade 312 and the combing plate 23 as soft rubber, so that the first blade 312 and / or the combing plate 23 deforms when squeezed by food, thereby reducing the risk of food getting stuck in the first blade 312 and / or the combing plate 23.

[0059] In some embodiments, as Figure 2 and Figure 3 As shown, the food storage bin 1 and the food distribution bin 2 can be made of hard plastic, such as a synthetic material of polylactic acid and copolyester, which makes the food storage bin 1 and the food distribution bin 2 biodegradable, will not pollute the environment, and is beneficial to the health of pets.

[0060] In some embodiments, as Figure 2 and Figure 4 As shown, the rotating mechanism 3 also includes a second impeller 36. The second impeller 36 is disposed at the bottom of the grain storage tank 1 and is fixedly connected to the first wheel shaft 311; wherein, in the radial direction of the second impeller 36, the second impeller 36 extends to the first opening 11.

[0061] In this embodiment of the invention, the second impeller 36 is configured to rotate along with the first impeller 31, thereby agitating the food at the bottom of the grain storage bin 1. This prevents the food at the bottom of the grain storage bin 1 from getting stuck at the first opening 11, reducing the risk of blockage inside the feeder.

[0062] In some embodiments, as Figure 5 As shown, at least one set of infrared detection devices 7 is provided on the side wall of the grain storage tank 1. The infrared emitters of each set of infrared detection devices 7 are opposite each other, that is, one infrared detection device 7 is used to transmit signals and the other infrared detection device 7 is used to receive signals.

[0063] Under normal use, if the height of the food in the grain storage bin 1 is higher than the height of the infrared detection device 7, the infrared detection device 7 will not receive an infrared signal, indicating that there is enough food in the grain storage bin 1. If the height of the food in the grain storage bin 1 is lower than the height of the infrared detection device 7, the infrared detection device 7 will not receive an infrared signal, indicating that there is too little food in the grain storage bin 1.

[0064] This embodiment of the invention uses an infrared detection device 7 to detect whether there is enough food in the grain storage bin 1. If there is too little food in the grain storage bin 1, the user can be prompted to add food.

[0065] In some embodiments, as Figure 2As shown, a gravity detection device 6 is installed at the bottom of the food bowl 5 to detect the weight of the food inside. The gravity sensor can be composed of a spring, a damper, and a sensor chip. When the spring is subjected to the gravity of the food bowl 5 and the food inside, the spring and damper limit and attenuate the displacement, while the sensor chip converts the displacement into an electrical signal output. This allows the user to determine the amount of food in the food bowl 5 and decide whether to add more food.

[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
