Description

Technical Field

[0001] This utility model relates to the field of feeder technology, specifically a moisture-proof feeder structure. Background Technology

[0002] Pet feeders are primarily used for storing and dispensing pet food. Through their internal controller, pet food is automatically dispensed in measured amounts and timed intervals, collecting in a container below the feeder's outlet. This is more efficient and convenient than manually scooping food from a bag and transferring it into the container. However, this design requires high moisture-proof performance within the internal pet food storage compartment. Existing feeders cannot guarantee complete isolation between the storage compartment outlet and the outside environment when not in use, resulting in poor moisture-proof performance. Utility Model Content

[0003] The purpose of this utility model is to provide a moisture-proof design for a feeder's grain channel structure so as to solve the problem that existing feeders cannot guarantee the isolation of the storage compartment outlet from the outside world when not in use, resulting in poor moisture-proof performance.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a moisture-proof feeder structure, comprising:

[0006] A baffle is rotatably disposed between the two supports, and a discharge chamber is formed between the discharge bin, the supports and the baffle. A material distribution impeller is rotatably disposed inside the discharge bin.

[0007] The discharge channel connects the opening and the feeder outlet. It has a stepped structure. The support extends to the inner side of the first vertical surface, and the discharge channel is provided with a second vertical surface. The first vertical surface and the second vertical surface meet to form a U-shaped stepped surface. The inner sides of the left and right ends and the inner side of the bottom end of the baffle are spliced ​​on the U-shaped stepped surface to block and seal the discharge chamber.

[0008] As a further description of the above technical solution:

[0009] The baffles are assembled between the brackets, and the top of the brackets has an installation groove. The rotating shaft on the side of the baffles is inserted into and rotatably connected to the installation groove.

[0010] As a further description of the above technical solution:

[0011] A torsion spring is also provided between the rotating shaft and the mounting groove.

[0012] As a further description of the above technical solution:

[0013] The U-shaped stepped surface is magnetically connected to the baffle.

[0014] As a further description of the above technical solution:

[0015] The discharge hopper has a recess that slopes downward from the inside out and extends laterally outward below the opening, and the bottom surface of the recess is located above the bottom surface of the vertically placed baffle.

[0016] As a further description of the above technical solution:

[0017] The discharge channel is provided with an inclined surface.

[0018] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0028] Please see Figure 1-3 This utility model provides a technical solution: a moisture-proof feeder structure, comprising:

[0029] The discharge bin 1 is located inside the feeder, with an opening on one side and supports 2 on both sides of the opening. The top of the discharge bin 1 and the supports 2 are sealed and connected to the grain storage bin.

[0030] A baffle 3 is rotatably mounted between the two supports 2. A discharge chamber 4 is formed between the discharge bin 1, the supports 2, and the baffle 3. A distributing impeller is rotatably mounted inside the discharge bin 1. The distributing impeller is driven to rotate by a motor at the bottom of the discharge bin 1, pushing the food inside to the opening and pushing the baffle 3 open to discharge the food. The top of the baffle 3 is attached to the bottom surface of the grain storage bin. The grain storage bin, together with the distributing impeller, supplies grain to the discharge bin 1.

[0031] The discharge channel 5 connects the opening and the feeder's outlet 6. It has a stepped structure. A first vertical surface 71 extends from the inner side of the support 2, and a second vertical surface 72 is provided on the discharge channel 5. The first vertical surface 71 and the second vertical surface 72 connect to form a U-shaped stepped surface 7. The inner sides of the left and right ends and the inner side of the bottom end of the baffle 3 fit onto the U-shaped stepped surface 7, sealing the discharge chamber 4. The discharge channel 5 has a segmented structure. The U-shaped stepped surface 7 ensures that the baffle 3 seals the discharge chamber 4 when the feeder is not in use. The channel gradually narrows from the outside to the inside, becoming wider at the outer side of the U-shaped stepped surface 7, making it easier to fit the baffle 3, thus isolating the discharge chamber 4 from the outside and achieving a moisture-proof function.

[0032] The baffle 3 is assembled between the brackets 2. The bracket 2 has an installation groove 8 on its top. The rotating shaft on the side of the baffle 3 is inserted into and rotatably connected to the installation groove 8.

[0033] A torsion spring is also provided between the rotating shaft and the mounting groove 8; the U-shaped stepped surface 7 is magnetically connected to the baffle 3, and magnets and magnetic materials are respectively arranged on the two. The magnets can be installed on the U-shaped stepped surface 7 or the baffle 3 according to the usage requirements, while the magnetic materials are arranged on another component. This forms an elastic pre-tightening force that rotates the bottom of the baffle 3 inward and a magnetic attraction between the U-shaped stepped surface 7 and the baffle 3, ensuring the sealing and moisture-proof effect.

[0034] The discharge bin 1 has a recess 9 that slopes downward from the inside out and extends laterally outward below the opening, and the bottom surface of the recess 9 is located above the bottom surface of the vertically placed baffle 3.

[0035] The feed outlet 5 is provided with an inclined surface 10. The stepped structure formed by the two together, through the design of the slope and the vertical surface, ensures that the food is tilted and guided at the notch 9, so that it has a certain initial velocity in the horizontal direction to be discharged from the feeder.

[0036] The working principle of the feeder moisture-proof design and feed channel structure in this embodiment includes: by driving the distributing impeller to rotate, it first touches and pushes the baffle 3 outward, and then pushes the food in the discharge chamber 1 to the notch 9. The food is discharged from the discharge chamber 4 through the gap between the notch 9, the baffle 3 and the feed channel 5, and flows obliquely along the feed channel 5, exiting the feeder from the outlet 6 and collecting in the food container. As the distributing impeller continues to rotate, it disengages from the baffle 3, which allows the baffle 3 to automatically reset under its own weight, torsion spring force and magnetic attraction, sealing and fitting onto the U-shaped stepped surface 7, thus isolating the discharge chamber 4 from the outside.

[0037] In summary, due to the adoption of the above technical solutions, the moisture-proof feeder structure of this embodiment has the following advantages compared with the prior art:

[0038] This utility model's feed channel structure, through a stepped discharge channel design, combined with a distributing impeller and a tilting baffle, allows for switching between open discharge and sealed storage states, achieving moisture-proof functionality. The discharge channel is segmented, with a U-shaped stepped surface ensuring the baffle seals the discharge chamber when the feeder is not in use. The channel gradually narrows from the outside to the inside, becoming wider at the outer edge of the U-shaped stepped surface. This structural design, combined with torsion springs and magnetic connections, makes it easier for the discharge channel to fit the baffle, ensuring the discharge chamber is isolated from the outside environment and providing stable sealing and moisture-proof effects. The concave and inclined surface design ensures efficient food discharge.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
