[0026] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0027] Example 1: Figures 1 to 6 As shown, this embodiment provides a vacuum fish food feeder, comprising an outer shell assembly 1, a grain storage bin 2, a movable bin 3, a movable bracket 4 and an eccentric wheel driving mechanism 5, wherein the grain storage bin 2 is arranged at the top of the outer shell assembly 1, and a grain outlet 21 is arranged at the bottom of the grain storage bin 2, the movable bin 3 is movably arranged in the outer shell assembly 1, below the grain storage bin 2, the movable bin 3 has a grain storage cavity 31 on the front side and a blocking portion 32 on the rear side, an opening 310 is provided at the bottom of the grain storage cavity 31, and a flap 6 for opening or closing the opening is provided at the opening 310, the eccentric wheel driving mechanism 5 and the movable bracket 4 are both arranged in the outer shell assembly 1, the eccentric wheel driving mechanism 5 is connected to the movable bin 3 through the movable bracket 4, and the eccentric wheel driving mechanism 5 drives the movable bin 3 to move through the movable bracket 4 so that the grain storage cavity 31 is opposite to the grain outlet 21 or the blocking portion 32 closes the grain outlet 21.

[0028] This embodiment provides a vacuum fish feeder with a simple structure and more reliable performance. Specifically, the eccentric wheel drive mechanism 5, the movable bracket 4, and the movable chamber 3 cooperate to drive the movable chamber 3. The cooperation between the various components is stable and reliable, and the failure rate is low.

[0029] At the same time, when the movable bin 3 is in the closed position, the grain outlet 21 is arranged opposite to the grain storage cavity 31, and the flap 6 is pressed tightly. At this time, the opening 310 is in a closed state, and the fish food in the grain storage bin 2 can flow into the grain storage cavity 31 through the grain outlet 21 and be stored in the grain storage cavity 31.

[0030] When the movable chamber 3 is in the open position, the blocking portion 32 is positioned opposite the grain outlet 21, closing the grain outlet 21 to prevent the fish food in the grain storage chamber 2 from leaking out. Simultaneously, the flap 6 rotates downward to open the opening 310, allowing the fish food in the grain storage chamber 31 to be dropped into the fish tank through the opening 310, thus completing the feeding of the fish food. During the entire feeding process, the vacuum state in the grain storage chamber 2 is maintained, preventing air from entering the grain storage chamber and causing the fish food to become damp or deteriorate.

[0031] In this embodiment, the eccentric wheel driving mechanism 5 includes a motor 51 and an eccentric wheel 52, wherein the eccentric wheel 52 is arranged on the rotating shaft of the motor 51, and the movable bracket 4 includes an eccentric connecting part 41, a limiting part 42 and a connecting rod part 43, wherein the eccentric connecting part 41 is connected to the eccentric wheel 52, and the limiting part 42 is connected to the outer shell assembly 1 for limiting the movable bracket 4 to only perform linear reciprocating movement, and the connecting rod part 43 is connected to the movable warehouse 3. It has a simple structure and a reasonable and ingenious design. By realizing the linear reciprocating movement of the movable bracket 4, the movable warehouse 3 is driven to reciprocate between the open position and the closed position, ensuring that the movement of the movable warehouse 3 is stable and reliable.

[0032] Furthermore, the limiting portion 42 includes a strip-shaped limiting hole 420 extending along the linear reciprocating direction of the movable bracket 4. A limiting column 11 is provided on the outer shell assembly 1, and the limiting column 11 is inserted into the strip-shaped limiting hole 420. It has a simple structure and a reasonable design, thereby limiting the movable bracket 4 to only perform linear reciprocating movement, allowing the movable bin 3 to reciprocate between the open position and the closed position, thereby avoiding the situation where the movable bin 3 is offset and causes the fish feed to leak out.

[0033] Furthermore, the flap 6 is rotatably connected to the rear side of the opening 310, and a spring 7 is provided at the connection between the flap 6 and the movable bin 3. The spring 7 enables the flap 6 to maintain the state of opening the opening 310 when the movable bin 3 is in the open position, thereby avoiding the situation where fish food accumulates in the food storage cavity 31 and cannot be discharged due to the inability to open the flap 6, thereby ensuring the smooth discharge of food from the movable bin 3.

[0034] Preferably, a food guide structure 71 extending toward the interior of the food storage cavity 31 is provided on the spring 7. During the rotation of the spring 7, the food guide structure 71 can be moved back and forth in the food storage cavity 31 to move the fish food in the food storage cavity 31, thereby preventing the flake fish food from bridging and causing the opening 310 to be blocked or stuck, thereby ensuring smooth food discharge.

[0035] In this embodiment, the food guide structure 71 is a needle-shaped structure. Of course, the food guide structure 71 can adopt other structures as long as it can stir the fish food in the food storage chamber 31 to prevent the opening 310 from being blocked or stuck due to the formation of fish food flakes.

[0036] In this embodiment, a through hole 12 is provided on the outer shell component 1 to allow the movable bin to pass through, a connecting member 8 is provided at the front end of the connecting rod portion 43, the movable bin 3 is fixedly connected to the inner side of the connecting member 8, and a sealing member 91 is provided on the inner side surface of the connecting member 8. The sealing member 91 seals the through hole 12 when the movable bin 3 is in the closed position. After the feeding of the fish food is completed, the external air can be prevented from entering the grain storage bin 2 through the through hole 12, and a relative vacuum state can be maintained in the grain storage bin 2 to prevent air from entering the grain storage bin and causing the fish food to become damp and deteriorate.

[0037] Furthermore, a silicone member 92 is provided in front of the grain outlet 21 and inside the grain storage bin 2. When the movable bin 3 moves from the closed position to the open position, the lower end of the silicone member 92 can contact the rear side of the grain storage cavity 31 and the movable bin 3. The upper surface of the silicone member 92 is provided as an arc-shaped grain guide surface 920, thereby ensuring that the fish food in the grain storage bin 2 can smoothly enter the movable bin 3. More importantly, hard contact between the front side of the grain outlet 21 and the inner wall of the grain storage bin 2 and the rear side of the grain storage cavity 31 and the movable bin 3 can be avoided. When fish food is stuck between the two, it is easy to get stuck, making it impossible for the movable bin 3 to continue opening or return to its original position.

[0038] Furthermore, a control module 13, a travel switch 14, a vacuum pump 15 and a power module 16 are provided on the housing assembly 1, and the control module 13 is electrically connected to the travel switch 14, the vacuum pump 15 and the power module 16 respectively, wherein the travel switch 14 cooperates with the movable bracket 4, thereby ensuring the accuracy of each stroke of the movable bracket 4, for example, the movable bracket 4 can be correctly reset, and the vacuum pump 15 is used to vacuum the grain storage bin 2, thereby forming a vacuum state in the grain storage bin 2, and vacuum storage of fish food can better preserve the fish food and reduce or avoid the occurrence of fish food deterioration.

[0039] In this embodiment, a clamping assembly 17 is provided at the bottom of the housing assembly 1. The clamping assembly 17 includes a clamping plate 171 and a screw 172. A first mounting plate 101 and a second mounting plate 102 are spaced apart at the bottom of the housing assembly 1. The clamping plate 171 is provided between the first mounting plate 101 and the second mounting plate 102. One end of the screw 172 passes through the first mounting plate 101 and is connected to the clamping plate 171. The structure is simple, thereby realizing the installation and fixation of the fish feeder, and the installation reliability is higher, thereby preventing the fish feeder from falling.

[0040] Furthermore, a guide column 173 is provided on the clamping plate 171, and a guide hole 1010 is provided on the first mounting plate 101. The guide column 173 can be movably inserted into the guide hole 1010. Its structure is simple, thereby ensuring the moving direction of the clamping plate 171 and ensuring that the clamping plate 171 remains relatively horizontal, thereby allowing the clamping plate 171 to better contact the fish tank glass, thereby improving the reliability of the fish feeder installation.

[0041] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
