Description

Technical Field

[0001] The utility model relates to the technical field of experimental animal breeding, in particular to a mouse breeding cage which is convenient for replacing feed. Background Art

[0002] SPF mice, or Specific Pathogen Free mice, refer to experimental mice that do not carry major potential infections or conditional pathogens and pathogens that interfere with scientific experiments, except for pathogens that should be excluded from clean animals. The breeding and management of SPF mice need to follow strict operating procedures and regulations to ensure their health status and the reliability of experimental results. This includes the control of the breeding environment (such as temperature, humidity, light, etc.), the nutrition and hygiene of the feed, regular microbial monitoring, and professional training of breeding staff.

[0003] The feed for SPF mice should be sterile and highly nutritious to meet their growth, development and reproduction needs. The feed should be changed regularly, with a 3-4 day supply each time to prevent the feed from spoiling. At the same time, supplementary foods such as cooked eggs and sterilized sunflower seeds can be added according to the breed and nutritional needs of the mice.

[0004] The EVC type mouse cage system (EVC) is a successor to the IVC mouse cage system. It can deliver clean air to each independent animal room through HVAC (building ventilation purification system), and use the pressure in the animal room to deliver clean air with relative temperature and humidity to each ventilation cage. At the same time, the siphon principle is used to discharge the exhaust gas in the cage naturally through the exhaust duct without power (or use the room exhaust system to discharge), forming an air flow process.

[0005] The feed in the mouse breeding cage of the existing EVC system is generally placed in a sealed cage. The breeding cage needs to be opened each time the feed is changed. After the change, the pressure inside the cage needs to be readjusted by the fan to maintain a negative pressure environment inside the cage, which increases the workload of the experimenters and reduces the work efficiency.

[0006] Currently, no effective solution has been proposed for the problem that the negative pressure in the existing EVC mouse breeding box needs to be readjusted when changing feed in the related art. Utility Model Content

[0218] (I) Usage status

[0219] When there is no need to replace the feed, the opening element 33 is sealed and connected to the base element 31 , and at this time, the cleaning element 71 is located on the top of the first isolation element 41 .

[0220] (ii) Change of feed

[0221] When the feed needs to be replaced, the third rotating element 61 is pressed downward and rotated to make the cleaning element 71 rotate along the central axis of the base element 31;

[0222] When the cleaning element 71 rotates to the second cavity, the first isolation element 41 and the second isolation element 51 are ensured to abut against each other. At this time, a first cavity is formed between the second isolation element 51, the first isolation element 41 and the base element 31. The first cavity is a sealed cavity.

[0223] Open the opening element 33, pour new feed into the first cavity, and then close the opening element 33;

[0224] Press down again and rotate the third rotating element 61, at this time the old feed on the second grid element 22 enters the interior of the cleaning element 71, and the new feed on the first isolation element 41 slides down onto the second grid element 22 under the push of the second isolation element 51;

[0225] When the cleaning element 71 is located below the opening element 33, ensure that the first isolation element 41 and the second isolation element 51 are against each other, open the opening element 33 and take out the cleaning element 71, and after cleaning the old feed, put the cleaning element 71 back into the base element 31 to complete the feed replacement.

[0226] The advantage of the utility model lies in that, by arranging a first isolation unit and a rotatable second isolation unit at the bottom of the base unit, two independent sealed cavities are formed inside the base unit. When changing the feed, the box body can be kept in a sealed state, thereby ensuring the negative pressure environment inside the box body, saving the step of changing the feed, and solving the problem of the existing EVC mouse breeding box needing to readjust the negative pressure in the box when changing the feed.

[0227] Example 2

[0228] This embodiment is a supplementary embodiment of Embodiment 1.

[0229] like Fig.10As shown, the first isolation unit 40 further includes a third limiting element 43. The third limiting element 43 is disposed at the rotational connection position between the first isolation unit 40 and the second isolation unit 50, and is limitedly connected to the second isolation unit 50, for limiting the rotation angle of the second isolation unit 50 when the base unit 30 is opened.

[0230] Specifically, the third limiting element 43 is disposed on a side of the first rotating element 42 .

[0231] In some embodiments, the third limiting element 43 and the first rotating element 42 are integrally formed.

[0244] In some embodiments, there are a plurality of fourth limiting elements 56. The plurality of fourth limiting elements 56 are evenly distributed around the center of the rotating drum.

[0245] The size of the fourth limiting element 56 matches the size of the second rotating element 52. Generally, the axial size (such as height) of the fourth limiting element 56 is smaller than the axial size (such as height) of the rotating cylinder, and the radius of the fourth limiting element 56 is smaller than the inner diameter of the rotating cylinder.

[0246] The size of the fourth limiting element 56 matches the size of the third limiting element 43. Generally, the radial size of the fourth limiting element 56 is not less than the radial size of the third limiting element 43.

[0247] In some of the embodiments, the fourth limiting element 56 is a limiting groove.

[0248] The advantage of this embodiment is that by setting a third limiting element on the side of the first isolation unit and a fourth limiting element inside the second isolation unit, the second isolation unit will not rotate easily when cleaning the cleaning unit, thereby avoiding the situation where the negative pressure environment in the box is destroyed due to accidental touching of the second isolation unit.

For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
