[0021] The utility model provides a kind of pet feeder grain outlet rotary body sealing structure, to make the purpose, technical scheme and effect of the utility model more clearly, the following is further detailed to the utility model.It should be understood that the specific embodiments described herein are only to explain the utility model, and are not used to limit the utility model.

[0022] Please refer to Figures 1 to 5 The utility model provides a kind of pet feeder grain outlet rotary body sealing structure.The accompanying drawings are only used to explain the structure principle, not proportional to actual product.The accompanying drawings only draw the structure related to the invention point of the present application, and the conventional structure is not specifically drawn in this paper.The "first", "second" and other expressions described in this paper are only different naming for similar structures to facilitate exposition, not to limit the present application.As prior art (for example: the patent with the authorization announcement No.CN219679472 U) has disclosed the structure of entire pet feeder, the structure of entire pet feeder is not specifically drawn in the present application.

[0023] A kind of pet feeder grain outlet rotary body sealing structure, including shell 1 and the rotary body 2 being arranged in shell, grain outlet 101 is provided on shell, at least one recess 201 is provided on the lateral wall of rotary body;The outer edge of the upper surface of rotary body is provided with first protruding part 221;The side and bottom of each recess are provided with second protruding part 222;The lateral wall of rotary body is further provided with third protruding part 223, and the shape of the third protruding part is adapted to the shape of grain outlet.The above-mentioned first protruding part, second protruding part and third protruding part are respectively contacted with shell, and play the role of sealing, since only each protruding part is contacted with shell, so that rotary body can rotate normally during rotation.

[0024] It can be understood that the width of the above-mentioned second protruding part and third protruding part in the circumferential direction is greater than the width of the grain outlet, to ensure that the inner wall of the shell is contacted by the second protruding part or the third protruding part when the grain outlet is in the open or closed state (so that the second protruding part or the third protruding part will not be partially exposed from the grain outlet), thereby ensuring normal sealing.

[0025] In practical application, rotary body can have two movement directions of forward rotation and reverse rotation, therefore, at least two recesses can be provided on the lateral wall of rotary body, and the two recesses are of the same specification;The third protruding part is located between the two recesses.Forward rotation or reverse rotation can make one recess align with the grain outlet to realize grain outlet, and each recess is provided with a second protruding part to ensure that pet food will not enter the gap between the lateral wall (or bottom) of the recess and the shell.When two recesses are provided, the third protruding part 223 actually includes two end arc structures (as shown in Figure 4 ), instead of a continuous arc.

[0026] Preferably, the first, second and third protrusions have equal outward protruding sizes (i.e. equal outward protruding heights). This arrangement allows the first, second and third protrusions to be in contact with the inner wall of the shell at all positions, avoiding the situation that some positions of the protrusions are not in contact with the inner wall of the shell due to size difference.

[0027] Preferably, the first, second and third protrusions have equal thicknesses. This arrangement allows the frictional forces between the first, second and third protrusions and the inner wall of the shell to be substantially equal, ensuring smooth rotation of the rotating body.

[0028] Further, as shown in Figure 5 the rotating body 2 comprises a skeleton 21 and a covering member 22, and the first, second and third protrusions are arranged on the covering member. The skeleton is made of engineering plastic, ensuring sufficient hardness and mechanical strength, while the covering member has certain elasticity, allowing it to be in close contact with the inner wall of the shell and thus ensuring good sealing performance.

[0029] Preferably, the first, second and third protrusions and the covering member are integrally formed. This arrangement facilitates the manufacturing of the first, second and third protrusions.

[0030] Preferably, the first, second and third protrusions and the covering member are made of silicone or rubber. In actual applications, the first, second and third protrusions and the covering member can be integrally formed through a mold, improving production efficiency.

[0031] It can be understood that, for those skilled in the art, equivalent replacements or changes can be made according to the technical scheme and the inventive concept of the present application, and all such changes or replacements shall fall within the protection scope of the present application.
