[0058] According to this embodiment, a pet feeder that realizes the nutritional ratio of food has two different storage compartments inside, one is the storage compartment for pet food, and the other is the storage compartment for health food. The two storage compartments do not interfere with each other, and each has an independent food delivery system. It can meet the feeding needs of the user and store staple food and a variety of health foods in the device at the same time. While the device automatically feeds the pet staple food, it can also automatically feed the pet health food pre-stored in the device, solving the need for more automated healthy pet feeding, completely freeing up hands, and truly achieving both automatic feeding and ensuring balanced nutrition for pets.

[0059] Optionally, in one embodiment, the refill bin 30 is located between the main body 10 and the primary grain bin 20. The refill bin 30 is an annular structure and is adaptively mounted within the cavity structure via a support frame located above the bottom of the cavity structure or a support member configured on the inner sidewall of the cavity structure. The lower end of the primary grain bin 20 extends through the hollow portion of the refill bin 30 into the cavity structure of the main body 10. This structural design makes the overall structure of the pet feeder that achieves nutritionally balanced food compact and takes up little space. The provision of an annular step and the extension of the lower end of the primary grain bin through the refill bin 30 into the cavity of the main body 10 enhance stability and prevent tipping.

[0060] Optionally, in one embodiment, the main granary 20 includes a main granary body 21, a top cover 22 and a cylinder 23.

[0061] The main grain bin body 21 is a barrel-shaped structure with an open top. The top cover 22 is provided on the top of the main grain bin body 21.
