[0027] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0028] Embodiment 1: Figures 1 to 6As shown, the present embodiment provides a vacuum fish feeder, comprising an outer shell component 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 on the top of the outer shell component 1, the bottom of the grain storage bin 2 is funnel-shaped and a grain outlet 21 is arranged at the bottom thereof, a sealing cover is arranged on the top of the grain storage bin, the movable bin 3 can be movably arranged in the outer shell component 1 and 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. 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.

[0029] This embodiment provides a vacuum fish feeder with a simple structure and more reliable performance. Specifically, the movable bin 3 can be driven by the cooperation of the eccentric wheel driving mechanism 5, the movable bracket 4 and the movable bin 3, and the cooperation between the various components is stable and reliable, and the failure rate is low.

[0030] 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 chamber 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 chamber 31 through the grain outlet 21 and be stored in the grain storage chamber 31.

[0031] When the movable bin 3 is in the open position, the blocking part 32 is arranged opposite to the grain outlet 21, and the blocking part 32 closes the grain outlet 21 to prevent the fish food in the grain storage bin 2 from leaking out. At the same time, the flap 6 rotates downward to open the opening 310, and the fish food in the grain storage cavity 31 is put into the fish tank through the opening 310, thereby completing the feeding of the fish food. During the entire feeding process, the vacuum state in the grain storage bin 2 can be maintained to prevent air from entering the grain storage bin and causing the fish food to be damp and deteriorate.

[0032] 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, thereby ensuring the stable and reliable movement of the movable warehouse 3.

[0033] Furthermore, the limiting portion 42 includes a strip limiting hole 420 extending along the linear reciprocating direction of the movable bracket 4, and a limiting column 11 is arranged on the outer shell assembly 1, and the limiting column 11 is inserted into the strip 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 preventing the movable bin 3 from deviating and causing fish food to leak out.

[0034] 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, so that the flap 6 can maintain the opening 310 in the open position of the movable bin 3 through the spring 7, thereby avoiding the situation that fish food is accumulated 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.

[0035] Preferably, a grain guiding structure 71 extending toward the interior of the grain storage cavity 31 is provided on the spring 7. During the rotation of the spring 7, the grain guiding structure 71 can be moved back and forth in the grain storage cavity 31 to move the fish grain in the grain storage cavity 31, thereby preventing the flake fish grain from bridging and causing the opening 310 to be blocked or stuck, thereby ensuring smooth grain discharge.

[0036] In this embodiment, the food guide structure 71 adopts 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 cavity 31 to avoid the situation where the opening 310 is blocked or stuck due to the bridging of the flakes of fish food.

[0037] 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 fish food is completed, 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.

[0038] Furthermore, a silicone member 92 is provided in the front side of the grain outlet 21 and in 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, and 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, the hard contact between the front side of the grain outlet 21, the inner wall of the grain storage bin 2, the rear side of the grain storage cavity 31 and the movable bin 3 can be avoided. When the fish food is stuck between the two, it is easy to get stuck, causing the movable bin 3 to be unable to continue to open or return.

[0039] 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.

[0040] A power supply compartment is arranged on the housing component, the power supply module is arranged in the power supply compartment, and a detachable compartment cover is arranged on the top of the power supply compartment.

[0041] In this embodiment, a clamping assembly 17 is arranged at the bottom of the housing assembly 1, and 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, and the clamping plate 171 is arranged 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. Anti-slip grooves are arranged on the clamping surface of 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.

[0042] 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. The 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 with the fish tank glass, thereby improving the reliability of the installation of the fish feeder.

[0043] The above 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 creative concept of the present invention, which all belong to the protection scope of the present invention.
