The two suction cup assemblies 40 are arranged relative to each other, and two adjacent legs 30 can be detachably installed on one of the suction cup assemblies 40, and the other two legs 30 can be detachably installed on the other suction cup assembly 40.

[0044] Specifically, the pet feeder of the present application includes an upper shell assembly 10, which has a grain storage bin 11 formed therein for storing pet food. The upper shell assembly 10 is mounted above the lower shell assembly 20, which has a square three-dimensional structure. Four legs 30 are mounted at the lower end of the lower shell assembly 20, and the four legs 30 are mounted at the four corners of the lower shell assembly 20 to support the lower shell assembly 20 and the upper shell assembly 10. There are two suction cup assemblies 40, and the two suction cup assemblies 40 are spaced below the four legs 30. Each suction cup assembly 40 includes two suction cups 41, and the two suction cup assemblies 40 include a total of four suction cups 41. The four suction cups 41 are all used to adhere to the ground, so that the suction cup assembly 40 is fixed to the ground. Two adjacent legs 30 of the four legs 30 can be detachably mounted on one of the suction cup assemblies 40, and the other two legs 30 can be detachably mounted on the other suction cup assembly 40. The present application comprises four legs 30 detachably mounted on two suction cup assemblies 40, allowing for assembly and disassembly of the four legs 30 and the suction cup assemblies 40. When in use, the four suction cups 41 secure the legs 30 to the ground, preventing larger pets from knocking over and disrupting the device's operation. The four suction cups 41 securely hold the four legs 30, along with the pet feeder, to the ground. However, due to the presence of four suction cups 41 and the simultaneous attachment of the four legs 30 to the ground, removing the suction cups 41 can be difficult. With the four legs 30 detachably attached to the suction cup assemblies 40, when the pet feeder needs to be relocated, the four legs 30 can be removed from the suction cup assemblies 40 first. Without the constraints of the four legs 30 and the upper and lower housing assemblies 10 and 20, the suction cups 41 beneath the suction cup assemblies 40 can be easily removed. The present application can be stably fixed on the ground to prevent large pets from knocking over it, and the suction cup 41 can be easily removed and placed in a different position when changing location or for other reasons.

The toggle block 4413 on the first rack plate portion 4412 extends from the toggle rail opening 4221, allowing the user to toggle the toggle block 4413 from the outside. During use, the user toggles the toggle block 4413 to move the first rack plate portion 4412, and the transmission gear member 45 engages with the first rack plate portion 4412, causing the transmission gear member 45 to rotate and drive the second rack plate to move within the slide rail groove 421, allowing the first plug plate 441 and the second plug plate 442 to move relative to the first mounting cavity 43 on both sides. It should be noted that a through hole can be provided on the first installation cavity 43 for the first plug-in plate 441 and the second plug-in plate 442 to pass through, and a bayonet 34 is provided at the position corresponding to the through hole at the lower end of the support frame 30. The first plug-in plate 441 and the second plug-in plate 442 are inserted into the bayonet 34 in the horizontal direction so that the support frame 30 cannot be pulled out of the first installation cavity 43.

[0052] In an optional embodiment, the first plug plate 441 also includes a third plug portion 4414, the second plug plate 442 also includes a fourth plug portion 4423, the main body shell 42 has two exposed openings 424 corresponding to the third plug portion 4414 and the fourth plug portion 4423, the grain bowl 50 includes two pin portions 51, the two pin portions 51 are respectively inserted into the two exposed openings 424, and the third plug portion 4414 and the fourth plug portion 4423 are inserted into the pin portions 51.

The sliding buckle assembly 33 can switch between two states: engaging with the latching groove 211 and disengaging from the latching groove 211, thereby allowing the support leg 30 to be removed from the positioning recess 21. The support leg 30 is provided to increase the height difference between the lower shell and the food bowl. Therefore, the length of the support leg 30 cannot be too short. If the support leg 30 is not removable, the height of the entire pet feeder packaging box must include the sum of the distances between the upper shell assembly 10, the lower shell assembly 20, and the upper end of the support leg 30 and the ground. This results in a larger packaging box for the pet feeder, significantly increasing the cost of the packaging box. The larger packaging box also increases the shipping cost of the pet feeder. The support bracket 30 of the present application can be removed from the lower shell. After the support bracket 30 is removed, the four support brackets 30 can be placed in the grain storage bin 11 in the upper shell assembly 10, so that the volume of the packaging box can be greatly reduced, thereby greatly reducing the cost of the packaging box and the transportation cost.

The rotating disk assembly 26 includes a rotating disk 261 and a plurality of grain pushing pieces 262. The rotating disk 261 includes a first circular plate portion 2611 and a first convex wall ring portion 2612. The first convex wall ring portion 2612 is disposed in the middle of the first circular plate portion 2611 and abuts against the bottom wall of the second groove cavity 221. The plurality of grain pushing pieces 262 are fixed to the first convex wall ring portion 2612 so that the grain pushing pieces 262 and the rotating disk 261 move synchronously. The fixed plate assembly 27 is disposed above the rotating disk 261 and includes a fixed disk 271 and a plurality of grain-blocking pieces 272. The fixed disk 271 includes a second circular plate portion 2711 and a second convex wall ring portion 2712. The diameter of the second circular plate portion 2711 is larger than the diameter of the second groove cavity 221. The upper end of the second groove cavity 221 has a positioning groove 2212 adapted for the second convex wall ring portion 2712, and the second circular plate portion 2711 is placed in the positioning groove 2212. The plurality of grain-blocking pieces 272 are fixed to the second convex wall ring portion 2712. The grain-diverting piece 28 is disposed above the second circular plate portion 2711 and is in transmission connection with the motor 24.

[0061] In this embodiment, the bottom plate 14 is a trumpet-shaped structure with a circular opening 141 at its lower end. The diameter of the circular opening 141 is smaller than that of the second circular plate portion 2711. The lower end of the bottom plate 14 abuts against the second circular plate portion 2711, thereby blocking the circular opening 141. The space above the bottom plate 14 constitutes the grain storage bin 11. The second circular plate portion 2711 has a first grain outlet 2713, the first circular plate portion 2611 has a second grain outlet 2613, and the bottom wall of the second recessed cavity 221 has a grain outlet 2211. The pet food in the grain storage bin 11 is moved by the grain moving piece 28 to fall from the first grain leakage port 2713 on the second circular plate portion 2711 to the first circular plate portion 2611. The rotating disk 261 rotates, so that the grain blocking piece 272 on the fixed disk 271 rotates relative to the rotating disk 261. Therefore, the grain blocking piece 272 on the fixed disk 271 can move the pet food above the first circular plate portion 2611 to leak from the second grain leakage port 2613 to the bottom wall of the second groove cavity 221. The rotation of the grain moving piece 28 on the rotating disk 261 can move the pet food on the bottom wall of the second groove cavity 221 out of the grain outlet 2211 into the grain bowl below for the pet to eat. In order to facilitate the smooth drop of pet food from the food outlet 2211 into the food bowl 50, a food guide 60 is provided on the two support legs 30. The food guide 40 has a food guide chute portion 61, and the food guide chute portion 61 connects the food outlet 2211 and the food bowl 50. The bottom plate 14 in this embodiment is directly placed on the second circular plate portion 2711, so the upper shell assembly 10 and the lower shell assembly 20 are detachable and can also be easily removed for cleaning. A buckle portion 142 is provided on the bottom plate 14, and the lower shell assembly 20 also includes a slide block 201 and a toggle block 202. The slide block 201 is slidably provided on the lower shell assembly 21 to lock the buckle portion 142. The toggle block 202 is installed on the slide and exposed to the outside for the user to toggle from the outside. When in use, the user pushes the toggle block 202 from the outside to drive the slide block 201 to slide, so as to fix the upper shell assembly and the lower shell assembly; when disassembling the upper shell assembly and the lower shell assembly, slide the toggle block 202 to slide the slide block 201 out of the buckle portion 142 to separate the upper shell assembly and the lower shell assembly.

[0062] In an optional embodiment, the storage bucket 13 is a blow-molded part, and the bottom plate 14 is an injection-molded part. Due to the large size of the storage bucket 13, if the storage bucket 13 is made by injection molding, the cost is very high. Although the cost is low if a blow-molded part is used, the dimensional accuracy of the blow-molded part is low and cannot meet the accuracy requirements for assembly with the lower shell assembly. The present application adopts an injection-molded bottom plate 14 provided below the storage bucket 13, and the injection-molded bottom plate 14 can meet the assembly requirements. Therefore, the present application adopts a blow-molded storage bucket 13 and then adapts an injection-molded bottom plate 14, which can meet the assembly requirements and greatly reduce costs.

[0063] In this embodiment, the lower end of the storage bucket 13 is tapered, and the upper end of the bottom plate 14 snaps into the tapered portion to install the bottom plate 14 and storage bucket 13 together. The tapered portion at the lower end of the storage bucket 13 is smaller than the upper end of the bottom plate 14. The bottom plate 14 and storage bucket 13 have a certain degree of flexibility and can both be appropriately deformed. During installation, the upper end of the bottom plate 14 can be inserted into the storage bucket 13 through the tapered portion at the lower end of the storage bucket 13, and then the upper end of the bottom plate 14 can be fully snapped into place through the opening above the storage bucket 13. Of course, in some embodiments, the opening at the upper end of the storage bucket 13 can be set larger than the upper end of the bottom plate 14, and the bottom plate 14 can be directly pressed into place from the upper end of the storage bucket 13.

[0064] The above description is merely a specific embodiment 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.
