The IVC device usually has environmental control functions such as temperature, humidity and light. It is necessary to set appropriate environmental parameters according to the physiological needs of mice. At the same time, it has a ventilation system to keep the air in the mouse breeding environment fresh and reduce pollutants in the air.
[0003] In the prior art, a large amount of food is stored in a feeding device used for raising mice. While the mice are eating the food, the feeding device will replenish the food in time to ensure that the mice get adequate nutrition.
[0004] However, when this feeding device is in use, mice have the characteristic of hoarding food, so they will hoard a lot of food. The hoarded food is placed in the cage, and the food is exposed to the air for a long time and will be contaminated, which will not only cause waste, but also be eaten by hamsters and cause disease.

[0031] Embodiment 1
[0032] This embodiment proposes a fully enclosed mouse feeding device, such as Figure 1 and Figure 2 As shown, it includes an IVC cage grid frame 1, a fully enclosed cage 2 with a closed cover is arranged in the grid opening of the IVC cage grid frame 1, and a feeding assembly 3 is arranged inside the fully enclosed cage 2. Figure 3 As shown, the feeding assembly 3 includes a food bin 31 and a feeding assembly. The feeding assembly is arranged inside the food bin 31 , and the food bin 31 is fixedly installed inside the fully enclosed mouse cage 2 .
[0033] like Figure 3 and 5 As shown, a locking assembly 6 is provided on the side of the fully enclosed mouse cage 2, and the locking assembly 6 includes a delay switch 61, an electric push rod 63, a stopper 64 and a pressure plate 65. The bottom of the pressure plate 65 is rotatably connected to the food bin 31, and a feeding assembly is provided at the bottom of the pressure plate 65. The mouse presses on the pressure plate 65 to make it rotate, and the pressure plate 65 presses down the feeding assembly to add one day's food to the mouse.
[0034] like Figure 5 As shown, a stop block 64 is fixedly installed at the end of the electric push rod 63, and the stop block 64 is located directly below the pressure plate 65. A support plate 62 is fixedly installed at the end of the electric push rod 63, and the bottom of the support plate 62 is fixedly connected to the food bin 31. The delay switch 61 is fixedly installed on the food bin 31 and is located below the pressure plate 65. The delay switch 61 is electrically connected to the electric push rod 63 through a controller: the stop block 64 adopts a triangular block structure, and an angle is formed between the pressure plate 65 and the food bin 31, and the angle is the same as the inclined angle of the triangular block. The food bin 31 is fixedly installed inside the fully enclosed squirrel cage 2.
[0035] like Figure 5As shown, the pressing plate 65 rotates to press down the feeding component and at the same time presses down the delay switch 61. The delay switch 61 extends the electric push rod 63 through the controller, and the stop block 64 lifts the pressing plate 65 to restore it to its initial state. At this time, the pressing plate 65 is separated from the delay switch 61. Due to the function of the delay switch 61 itself, the delay effect is achieved, and the electric push rod 63 shrinks afterwards. During this twenty-four hours, even if the mouse presses down the pressing plate 65 multiple times, since the stop block 64 is located below the pressing plate 65, the pressing plate 65 cannot rotate, that is, the mouse cannot press the pressing plate 65 multiple times within twenty-four hours, that is, food is only added once within twenty-four hours.
[0036] The food bin 31 adopts an L-shaped structure. A notch 5 is provided at the horizontal surface of the food bin 31 . The notch 5 is communicated with the interior of the food bin 31 . A magnetic cover is provided on the top of the food bin 31 to place food.
[0037] In this embodiment, the mouse presses the pressure plate 65 so that the feeding assembly adds food to the mouse. The pressure plate 65 presses down the feeding assembly and at the same time presses down the delay switch 61. The electric push rod 63 extends to make the block 64 press under the pressure plate 65, so that the pressure plate 65 cannot rotate. After twenty-four hours, the electric push rod 63 is reset, and the pressure plate 65 can press the feeding assembly again, so that food can only be added once in twenty-four hours, avoiding the mouse hoarding food and causing food to be contaminated and wasted, and preventing the mouse from eating contaminated food.
[0038] Embodiment 2
[0039] Based on the first embodiment, this embodiment proposes a fully enclosed mouse feeding device, such as Figure 3 and Figure 4 As shown, the feeding assembly includes a rotating shaft 33, a spiral piece 34, a rack plate 35, a first inclined block 36 and a second inclined block 37. Both ends of the rotating shaft 33 are rotatably connected to the food bin 31. The spiral piece 34 is fixedly installed in the middle of the rotating shaft 33. The bottom end of the spiral piece 34 is connected to the rack plate 35 through gear meshing. The end of the rack plate 35 is fixedly connected to the first inclined block 36. The top surface of the first inclined block 36 adopts an inclined surface structure. The second inclined block 37 contacts the top surface of the first inclined block 36.
[0040] By pressing the second inclined block 37 downward through the pressing plate 65, the first inclined block 36 moves and drives the rack plate 35, so that the shaft 33 rotates, and the food in the food bin 31 is driven downward through the spiral piece 34 on the shaft 33, and the food flows from the food bin 31 to the gap 5 for the mice to eat.
[0041] like Figure 4 As shown, a guide plate 4 is fixedly installed inside the food bin 31 and below the orifice plate 32. The guide plate 4 is tilted, and the rotating shaft 33 passes through the guide plate 4. The guide plate 4 is used to guide the food.
[0042] A perforated plate 32 is fixedly installed inside the food bin 31, and the diameter of the spiral sheet 34 is the same as the diameter of the perforated plate 32. The spiral sheet 34 closes the perforated plate 32 to prevent the food in the food bin 31 from falling directly from the perforated plate 32.
[0043] like Figure 5 As shown, the second inclined block 37 is located directly below the stepping plate 65, and extension plates are fixedly installed on both sides of the second inclined block 37, and a spring telescopic rod 38 is elastically connected between the extension plate and the food bin 31. The spring telescopic rod 38 is used to reset the second inclined block 37, that is, reset the stepping plate 65, and at the same time, the spring telescopic rod 38 weighs the weight of the mouse. The heavier the mouse is, the longer the distance that the stepping plate 65 presses the second inclined block 37 to move, the longer the distance that the first inclined block 36 and the rack plate 35 move, and the more turns the shaft 33 rotates.
[0044] The top of the rotating shaft 33 is connected to the connection point of the food bin 31 through a support block, and the top of the support block adopts an inclined structure to prevent food residues on the support block.
[0045] In this embodiment, the mouse presses the pressure plate 65, which presses down the second inclined block 37 and compresses the spring telescopic rod 38. The heavier the mouse, the longer the spring telescopic rod 38 is compressed, so that the more times the shaft 33 rotates, the greater the amount of food released by the spiral piece 34, thereby achieving the goal of controlling the amount of food added by using the weight of the mouse to avoid the problem of insufficient or excessive food.
[0046] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
