Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] As shown Figures 1-6 in the figure, the pet feeder in this embodiment includes a box body 1. Inside the box body 1, a first cylinder 2, a second cylinder 3, and a third cylinder 4 are coaxially arranged from inside to outside in sequence. Both ends of the first cylinder 2 are fixedly connected to the front and rear inner walls of the box body 1. The second cylinder 3 is sleeved on the first cylinder 2. A plurality of support plates 5 are connected between the outer wall of the second cylinder 3 and the inner wall of the first cylinder 2. The plurality of support plates 5 are arranged in a ring in sequence. There is a notch 6 on the second cylinder 3 between adjacent support plates 5. A grain outlet 7 is recessed on the first cylinder 2 to cooperate with the notch 6. The feed inlet 7 is arranged at the top of the first cylinder 2. The second cylinder 3 between adjacent support plates 5 can at least cover the grain outlet 7. A guide plate 8 is arranged inside the first cylinder 2. An opening 9 is arranged on the box body 1 to cooperate with the guide plate 8. A ring gear 10 is protruded on the outer wall of the third cylinder 4. A driving gear 11 is meshed with the ring gear 10. A motor 12 for driving the driving gear 11 to rotate is arranged inside the box body 1.

[0028] Furthermore, a pair of annular plates 13 are symmetrically arranged in the front and rear between the second cylinder 3 and the third cylinder 4. The inner and outer walls of the annular plates 13 are respectively fixedly connected to the outer wall of the second cylinder 3 and the inner wall of the third cylinder 4. The annular plates 13 are fixedly connected to the support plates 5. Feed inlets 14 are symmetrically arranged on a pair of annular plates 13 between adjacent support plates 5. The feed inlets 14 are arranged in a dislocation manner with respect to the notch 6.

[0029] In this technical solution, through the structural cooperation, the grain is automatically fed out through the notch, the discharge port, the guide plate, and the opening. When feeding is not required, the inner wall of the second cylinder covers the feed inlet, thereby closing the feed port and preventing insects, dust, etc. from entering the box body, ensuring the quality of the grain, and being beneficial to subsequent feeding.

[0030] As shown Figures 1-8 in the figure, in an embodiment, a box cover 15 is detachably connected to the box body 1.

[0031] Further, the rear side wall of the lid 15 is rotatably connected to the box body 1 through a rotating shaft 16. A pair of switch mechanisms 17 are provided on the front side of the lid 15. The switch mechanism 17 includes a pressing plate 1701, a moving plate 1702, a pair of rotating plates 1703, a baffle 1704 and a spring 1705. The baffle 1704 is fixed to the bottom surface of the lid 15. The pressing plate 1701 and the moving plate 1702 are respectively arranged on both sides of the baffle 1704. One end of the pressing plate 1701 facing the baffle 1704 is rotatably connected to the bottom surface of the lid 15 through a horizontal shaft 1706. A pair of rotating plates 1703 are symmetrically arranged on both sides of the horizontal shaft 1706. The rotating plate 1703 is fixedly sleeved on a vertical shaft 1707. The moving plate 1702 is provided with a long groove 1708 for the bottom end of the vertical shaft 1707 to be inserted. The long groove 1708 is perpendicular to the horizontal shaft 1706. The top end of the vertical shaft 1707 is rotatably connected to the bottom surface of the lid 15. The moving plate 1702 is provided with a pair of abutting blocks 1709. The pair of abutting blocks 1709 respectively abut against the end faces of the pair of rotating plates 1703 facing away from each other and away from the moving block 1702. A pair of vertical blocks 1710 are fixed to the bottom surface of the rotating plate 1703. The pair of vertical blocks 1710 respectively abut against the end faces of the pair of rotating plates 1703 facing each other and away from the moving block 1702. Both ends of the spring 1705 are fixedly connected to the end faces of the baffle 1704 and the moving plate 1702 facing each other. A clamping groove 101 is provided on the inner wall of the box body 1 corresponding to the position of the moving plate 1702. One end of the moving plate 1702 facing the clamping groove 101 extends into the clamping groove 101. A pressing hole 1501 for cooperating with the rotating plate 1703 is recessed on the lid 15.

[0032] Further, a groove 1711 is provided on the end face of the moving plate 1702 facing the baffle 1704. A limiting rod 1712 extending into the groove 1711 is fixed to the baffle 1704. The spring 1705 is sleeved on the limiting rod 1712.

[0033] Further, both the spring 1705 and the limiting rod 1712 are perpendicular to the horizontal shaft 1706.

[0034] In this technical solution, by pressing the rotating plate to drive the cooperation of each structure to move the moving plate out of the clamping groove, the separation of the lid and the box body is realized. On the contrary, the spring force makes the moving block snap into the clamping groove, realizing the quick opening and closing of the lid and the box body, which is convenient for discharging grain.

[0035] See Figure 1 、 Figure 7 As shown, in an embodiment, a frame body 18 is detachably connected to the bottom surface of the lid 15. A desiccant 19 is provided in the frame body 18.

[0036] In this technical solution, the quality of the grain is ensured by using the desiccant.

[0037] See Figure 2 As shown, in an embodiment, an infrared pair tube 20 is provided on the inner wall of the opening 9.

[0038] In this technical solution, the number of times of discharging grain and the situation of grain leakage can be monitored.

[0039] See Figure 2 As shown, in one embodiment, a transparent window 21 is provided on the outer wall of the box body 1.

[0040] In this technical solution, it is possible to see how much grain is left in the grain bucket from the outside, which is convenient for observing grain replenishment.

[0041] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
