Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a pet feeder. Background Technology

[0002] With the rapid development of smart pet devices, pet feeders are gradually evolving from basic feeding functions towards intelligence and interactivity. Modern users not only focus on the accuracy and reliability of feeding, but also expect to remotely monitor their pets' activity status through real-time monitoring and multi-angle observation.

[0003] While some pet feeders on the market are equipped with cameras, most use a single fixed-focus lens or a fixed dual-camera module, resulting in limited field of view and an inability to dynamically adjust the angle. For example, in traditional dual-camera feeders, the cameras are usually rigidly fixed, leading to overlapping coverage areas or blind spots between the main and secondary cameras. This makes it difficult to flexibly adjust the shooting angle according to the pet's activity height or environmental layout, resulting in blind spots or incomplete capture of key behaviors. Therefore, there is an urgent need to design a pet feeder that supports multi-view collaborative coverage, flexible adjustment, and strong structural stability. Utility Model Content

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0044] This utility model embodiment provides a pet feeder 1000, such as Figure 1 - Figure 6 As shown, the pet feeder 1000 includes a main body 10 and a camera assembly 20. The camera assembly 20 includes a main camera module 21 and a secondary camera module 22, both of which are mounted on the same side of the main body 10, with the secondary camera module 22 located beside the main camera module 21. The secondary camera module 22 is rotatably connected to the main body 10 via a rotating structure 30. The rotating structure 30 includes a retaining member 31 and a limiting member 32. The retaining member 31 is located on one of the secondary camera module 22 and the main body 10, and the limiting member 32 is located on the other of the secondary camera module 22 and the main body 10. The limiting member 32 has several grooves 3211 on the side facing the retaining member 31. By rotating the secondary camera module 22, the retaining member 31 can engage with any of the grooves 3211 to adjust the shooting angle of the secondary camera module 22. This application solves the problem that existing dual-camera feeders cannot adjust the shooting angle and have poor flexibility. The pet feeder 1000 not only has a larger shooting range, but also allows users to flexibly adjust the shooting angle according to monitoring or privacy needs, thus balancing flexibility and privacy security.

[0045] Specifically, firstly, the main camera module 21 is fixedly positioned to cover the surrounding environment of the subject 10 to observe the pet's daily activities, while the secondary camera module 22 is rotatably connected to the subject 10 using the rotating structure 30. Users can adjust the shooting angle of the secondary camera module 22 according to their own needs to supplement the shooting perspective of the main camera module 21. The shooting field of view of the main camera module 21 and the secondary camera module 22 complement each other to better monitor the pet and meet the user's shooting needs for specific scenarios (such as feeding monitoring and observation of climbing from high places). This pet feeder 1000 has better flexibility and stronger scene adaptability.

[0046] Secondly, by utilizing the multiple grooves 3211 of the retaining member 31 and the limiting member 32 to cooperate, multi-angle adjustment can be achieved while ensuring the stability of the viewing angle of the sub-camera module 22 after adjustment, avoiding the sub-camera module 22 from shifting, and its rotational connection has better stability and reliability.

[0047] It is worth mentioning that by implementing the above solution, users can actively steer the secondary camera module 22 towards the blind spot of the main camera module 21 or the area where pets frequently move, such as adjusting it upwards to capture the high-altitude behavior of cats and birds. This solves the problem of the rigid fixed dual-camera perspective of traditional pet feeders 1000, improves adaptability to different pet habits and home environments, and makes the monitoring function of the pet feeder 1000 more targeted and practical. Furthermore, when users are at home, they can adjust the shooting direction of the secondary camera module 22 to a location away from their living area, such as pointing the secondary camera module 22 towards a wall, so that the secondary camera module 22 actively avoids shooting in their living environment, effectively reducing the risk of privacy leaks.

[0048] Reference Figure 4 - Figure 8 In one embodiment, the front end face of the main body 10 is provided with an opening 11; a limiting member 32 is installed in the opening 11 and together with the main body 10 defines a rotating groove 40; the pet feeder 1000 also includes a mounting base 33, which is disposed at the opening 11. The secondary camera module 22 is disposed on the mounting base 33 with its camera end 221 exposed outside the main body 10. The mounting base 33 is provided with a rotating shaft 331, which is rotatably connected to the rotating groove 40, so that the mounting base 33 can rotate relative to the main body 10. With this configuration, the mounting base 33 can, on the one hand, install and fix the secondary camera module 22, and on the other hand, the user can apply pressure to the mounting base 33 to make it swing at the opening 11, so as to adjust the pitch angle or horizontal yaw angle of the secondary camera module 22. In addition, the mounting base 33 is rotatably connected to the rotating groove 40 through the rotating shaft 331, so that the rotational stability of the mounting base 33 is better when it rotates relative to the main body 10.

[0049] Specifically, the mounting base 33 is provided with a receiving groove 332, the groove opening of the receiving groove 332 is arranged opposite to the opening 11, the sub-camera module 22 is installed in the receiving groove 332, the bottom of the receiving groove is provided with a through hole, and the camera end 221 of the sub-camera module 22 passes through the through opening 151 and is exposed to the outside.

[0050] It is worth mentioning that by implementing the above embodiments, it is easier for users to adjust the angle of the secondary camera module 22. In order to better understand the above technical effects, the following is a description of the specific operation method. For example, users can directly press the mounting base 33 on both sides of its rotation path to make the mounting base 33 swing relative to the opening 11, thereby adjusting the shooting angle of the secondary camera module 22. The adjustment process is more convenient and efficient, greatly improving the user experience.

[0051] In one embodiment, the retaining member 31 is a tooth 311 disposed on the peripheral wall of the rotating shaft 331, and a plurality of tooth grooves 3211 are disposed around the tooth 311. The end of the tooth 311 away from the rotating shaft 331 is inserted into the tooth groove 3211, and the tooth 311 has a gradually narrowing tendency in the direction away from the rotating shaft 331, and the tooth groove 3211 has a gradually expanding tendency in the direction away from its bottom. With this design, the connection stability of the tooth 311 and the groove 3211 is better. Furthermore, since the end of the tooth 311 that engages with the groove 3211 is tapered, when the tooth 311 disengages from the current groove 3211, the tapered end will preferentially contact the widening groove of the adjacent groove 3211, avoiding hard collisions at the edges, thereby reducing friction and making the rotation adjustment smoother. In addition, the increased root width of the tooth 311 connected to the shaft 331 results in better structural strength, which can disperse torsional stress concentration, effectively prevent the root of the tooth 311 from breaking, and improve the overall structural reliability.

[0052] Specifically, the paddle 311 includes two first inclined surfaces arranged opposite to each other in its rotation direction. The distance between the two first inclined surfaces gradually shortens in the direction away from the rotating shaft 331. In this way, when the paddle 311 engages with any tooth groove 3211, the two first inclined surfaces can play a guiding role, thereby reducing the resistance of the paddle 311 when it is inserted into the tooth groove 3211, making the engagement of the paddle 311 with the tooth groove 3211 smoother.

[0053] Similarly, the arrangement of the tooth groove 3211 and the tooth 311 is consistent, and will not be repeated here.

[0054] Reference Figure 5 - Figure 7 In one embodiment, the limiting member 32 is detachably connected to the main body 10. The main body 10 is provided with a socket 12 adjacent to the opening 11. The side of the socket 12 facing away from the opening 11 is provided with a first slot 121. The limiting member 32 is also provided with an insert block 322. The side of the insert block 322 facing the socket 12 is provided with a second slot 3221. The insert block 322 is inserted into the socket 12 so that the first slot 121 and the second slot 3221 together form a rotating groove 40. This arrangement makes it easier to assemble and maintain the mounting base 33 and improves assembly efficiency.

[0055] To better understand the above technical effects, the following is a specific operational method. Since the limiting member 32 is detachably connected to the main body 10, the rotating shaft 331 can be first placed in the first slot 121, which covers one side of the rotating shaft 331. Then, the limiting member 32 is installed on the main body 10, and the insert 322 is inserted into the socket 12. At this time, the other side of the rotating shaft 331 is automatically placed in the second slot 3221. The first slot 121 and the first slot 122 cooperate to form a closed rotating groove 40, achieving the purpose of limiting the installation of the rotating shaft 331. Compared with the embodiment of inserting the rotating shaft 331 into the rotating hole, the entire installation process does not require precise alignment, which is more convenient and efficient. It is easier for assembly personnel to install, and the mounting base 33 can be safely separated by disassembling the limiting member 32, making maintenance more convenient.

[0056] Specifically, the socket 12 is symmetrically provided with positioning steps 122 on both sides, the first slot 121 is located between the two positioning steps 122, the plug 322 is provided with two locking posts 3222, the second slot 3221 is located between the two locking posts 3222, and the two locking posts 3222 are respectively locked at the two positioning steps 122 so as to realize the plug 322 being inserted into the socket 12.

[0057] Preferably, the rotating shaft 331 is cylindrical, the bottom of the first slot 121 has a first arc surface, and the bottom of the second slot 3221 has a second arc surface. The shapes of the first arc surface and the second arc surface are adapted to the rotating shaft 331. The rotating shaft 331 is clamped between the first arc surface and the second arc surface, so that the rotating shaft 331 can rotate more smoothly.

[0058] Reference Figure 9 and Figure 10 In one embodiment, two rotating shafts 331 are provided, symmetrically arranged on both sides of the mounting base 33. Two inserts 322 and two sockets 12 are also provided, forming two rotating grooves 40. The two rotating shafts 331 are rotatably connected to the two rotating grooves 40 respectively. With this arrangement, both sides of the mounting base 33 are connected to the corresponding rotating grooves 40 via rotating shafts 331, resulting in a more balanced force distribution on the mounting base 33 and further improving the stability of its rotation.

[0059] In one embodiment, each rotating shaft 331 is provided with a retaining member 31, and the limiting member 32 is provided with two sets of toothed grooves 3211 321. Each set of toothed grooves 3211 includes a plurality of toothed grooves 3211, and each set of toothed grooves 3211 corresponds one-to-one with each retaining member 31. With this configuration, after the mounting base 33 is adjusted to its relative position with respect to the opening 11, each side of the mounting base 33 has a retaining member 31 that engages with the corresponding toothed groove 3211. After adjustment, the mounting base 33 can stably maintain its relative position, improving the stability of the connection of the mounting base 33 and preventing accidental displacement of the mounting base 33.

[0060] There are many ways to connect and detach the main body 10 and the limiting member 32, such as magnetic connection, snap-fit ​​connection, and threaded connection, etc., which are not limited here. For example, in this application, the main body 10 has a plurality of connecting posts 13 arranged around the opening 11. The pet feeder 1000 also includes a plurality of screws, each screw passing through the limiting member 32 and threadedly connected to a connecting post 13. Thus, the limiting member 32 is installed onto the main body 10 by the tightening force of the screws, and the limiting member 32 can be detached from the main body 10 by loosening the screws.

[0061] For example, in this application, there are two connecting posts 13 and two screws. The two connecting posts 13 are located on both sides of the opening 11, and the two screws are threaded through the limiting member 32 and connected to one connecting post 13.

[0062] Reference Figure 9In one embodiment, the limiting member 32 is provided with a limiting groove 323, and a plurality of toothed grooves 3211 are disposed at the bottom of the limiting groove 323. The retaining member 31 passes through the limiting groove 323 to engage with any toothed groove 3211 at the bottom of the limiting groove 323. With this configuration, the limiting groove 323 can limit the maximum rotation range of the retaining member 31 and avoid interference between the retaining member 31 and other components, thereby improving the reliability of the rotation of the mounting base 33.

[0063] Reference Figure 3 , Figure 4 as well as Figure 11 In one embodiment, the main body 10 includes a base 14, a food storage bin 15, and a panel 16. The food storage bin 15 is mounted on the top of the base 14, and the front end face of the base 14 is provided with a mounting groove 141. The camera component 20 and the rotating structure 30 are both disposed on the panel 16, and the panel 16 covers the mounting groove 141. With this arrangement, the panel 16 can be separated from the base 14 during installation to install the camera component 20 and the rotating structure 30 without having to be inside the base 14, thus providing a larger operating and installation space and making installation more convenient. In addition, the panel 16 can also serve a decorative function for the base 14, enhancing the aesthetics of the pet feeder 1000.

[0064] There are many ways to detachably connect the panel 16 to the mounting groove 141. For example, it can be connected by magnetic attraction or snap-fit, etc., and the connection method is not limited here. For example, in this application, the mounting groove 141 is provided with a snap-fit ​​groove on the groove wall, and the panel 16 is provided with a snap-fit ​​block on the edge. When the panel 16 is placed on the mounting groove 141, the snap-fit ​​block is snapped into the snap-fit ​​groove.

[0065] It is worth mentioning that by implementing the above embodiments, the pet feeder can also replace different types of functional panels 16 according to different functions, giving users more diverse choices.

[0066] In one embodiment, the pet feeder 1000 further includes a main control board and a control component. The control component is mounted on the panel 16, with a portion of the control component exposed outside the panel. The main control board is mounted on the panel and located in a mounting slot, and is electrically connected to the control component and the camera component. Thus, the control component facilitates user operation of the pet feeder 1000.

[0067] Specifically, the control components include a display screen (not shown in the figure), a microphone (not shown in the figure), and several buttons 80; the display screen, microphone, buttons, and camera component 20 are all electrically connected to the main control board. The display screen can display information, the microphone is used to play sound, and the buttons 80 are designed to facilitate user control of the pet feeder 1000, thereby achieving better human-computer interaction.

[0068] Preferably, the panel 16 has a food outlet 161 communicating with the food storage bin 15, and the camera component 20 is located above the food outlet 161. The pet feeder 1000 also includes a feeding bowl 50, which is located at the bottom of the base 14 to receive the food discharged from the food outlet 161. This arrangement makes the overall structure more compact and ensures the relative position of the secondary camera module 22 and the food outlet 161, so that when the secondary camera module 22 takes a top-down shot, it can definitely cover the food discharge trajectory and the feeding bowl 50.

[0069] Reference Figure 11 In one embodiment, the grain storage bin 15 is detachably mounted on the base 14 to facilitate the user to remove the grain storage bin 15 for cleaning.

[0070] In one embodiment, the food storage bin 15 has an opening 151 at its bottom, and the base 14 has a receiving groove 142 on the side facing the food storage bin 15. The pet feeder also includes an electric dispensing mechanism 60, which includes a receiving component 61 and a rotary drive component 62. The receiving component 61 is rotatably connected to the receiving groove 142, and the receiving component 61 has several receiving ports in its rotation direction. The receiving ports are used to receive food from the food storage bin 15, and the bottom of the receiving groove 142 has a channel. 1421, channel 1421 is connected to the food outlet 161; channel 1421 is offset from the opening 151, and rotary drive 62 is connected to receiving component 61. Rotary drive 62 can drive the receiving component 61 to rotate, so that several receiving ports align with the opening 151 at the bottom of the food storage bin 15, so that each receiving port receives the food discharged from the opening 151, and drives each full receiving port to move to align with channel 1421, so that the food outlet 161 discharges the food. In this way, the receiving ports can control the amount of food, realize quantitative food dispensing, and multiple receiving ports receive food in advance. Each time food is dispensed, only the receiving component 61 needs to rotate a small angle to complete the food dispensing, making the food dispensing speed of this pet feeder 1000 more efficient. Specifically, rotary drive 62 is a motor.
