Description

Technical Field

[0001] This utility model relates to the technical field of laboratory animal husbandry equipment, specifically a feeding device for laboratory rat cages. Background Technology

[0002] In the field of biomedical experiments, experimental mice are used as the core model organism and are usually kept in groups in standardized cages.

[0003] Currently, when raising mice, feeding devices are installed in the cages to provide them with water and food. However, in practical applications, existing feeding devices often cause water droplets to splash when the mice suckle from the water dispensers. This dripping water mixes with the bedding, creating a damp environment. This not only increases the frequency of bedding replacement (typically every 3-5 days, significantly longer than the 7-10 day replacement cycle in dry environments), but also makes the damp bedding prone to bacterial growth, affecting the health of the mice and the accuracy of experimental data. Furthermore, the air filters in existing cages are usually built directly inside the cage, requiring the cage to be fully opened for replacement. This process may disturb the animals and increase the risk of stress. Therefore, there is an urgent need for a new feeding device for laboratory mice to solve these problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-6 The present invention provides a feeding device for a laboratory mouse cage. The present invention includes a cage body and a cover body. A water collection module is provided on the inner bottom wall of the cage body. The water collection module includes a water feeding platform fixedly connected to the inner bottom wall of the cage body. A collection trough for collecting fallen water droplets is opened on the top of the water feeding platform. A leakage hole is opened on the inner bottom wall of the collection trough. A pull-out box extending to the outer wall of the cage body is slidably connected inside the water feeding platform.

[0029] In this embodiment, in actual use, a placement component is fixedly connected to the top of the cover. The placement component is L-shaped, and a mouse drinker is provided on the inner wall of the placement component. The placement component is tilted to stably place the mouse drinker. The drinking nozzle of the mouse drinker 19 extends into the cage 1 and is located above the water feeding platform 3. Absorbent material, such as a sponge or lint-free cloth, can be filled into the pull-out box 6. The pull-out box 6 is used to receive dripping water discharged through the seepage hole. The pull-out box 6 can be cleaned by pulling it out.

[0030] Specifically, refer to Figure 2An air purification module is installed on the top of the cover. The air purification module includes a placement box fixedly connected to the top of the cover. An installation shell is inserted into the inside of the placement box. A filter element is inserted into the inside of the installation shell. The cover is placed on top of the cage. A mesh frame is set between the cover and the cage. An air inlet pipe connected to the placement box is fixedly connected to the back of the cover. An air outlet pipe is fixedly connected to the back of the cover.

[0031] In this embodiment, an air circulation system is installed on the mouse breeding rack in actual use. The air circulation system is a publicly known technology. When the cage 1 is placed on the breeding rack, a connecting pipe adapted to the air inlet pipe 14 and the air outlet pipe 15 is provided on the back of the breeding rack. The connecting pipe is connected to the air circulation system, so that the air inside the cage 1 can circulate. The air passes through the filter element 9 through the air inlet pipe 14. The filter element 9 is preferably made of activated carbon and HEPA composite filter material, so as to ensure the cleanliness of the air inside the cage 1.

[0032] Specifically, refer to Figure 5 The top of the mounting shell is fixedly connected to a mounting cover, the bottom of the mounting cover is fixedly connected to a first magnetic suction component, a slot is opened at the corresponding position on the top of the cover, and a second magnetic suction component that cooperates with the first magnetic suction component is fixedly connected to the inner bottom wall of the slot.

[0033] In this embodiment, in actual use, the placement box 7 has a hollow top structure, and the mounting shell 8 has a hollow bottom structure. Both the placement box 7 and the mounting shell 8 have air circulation holes that communicate with the cage body 1. The cooperation between the first magnetic component and the second magnetic component 13 enables quick assembly and disassembly, and ensures a certain degree of sealing.

[0034] The top of the cover has a feeding port, and a sealing plate is slidably connected inside the feeding port. When the feed is poured into the feeding port 16, the feed accumulates in the groove of the wire mesh frame 10. The sliding track of the sealing plate has anti-slip texture to ensure the sealing of the feed feeding port and prevent the feed from getting damp.

[0035] The cover has a rotatable buckle on its side wall, and the cage has a buckle seat that engages with the buckle on its side wall. The buckle design ensures a stable connection between the cover and the cage.

[0036] Working principle:

[0037] First: When the mice suck water through the mouth of the water bottle, the dripping water droplets first fall into the collection tank of the water feeding platform 3, and then seep through the leakage hole into the pull-out box below. The diameter of the leakage hole is matched with the water-absorbing material to ensure the water flow through while slowing down the flow speed to avoid splashing. The experimenter can pull out the pull-out box to clean up the water, and use the internal water-absorbing material to absorb the residual water droplets to avoid water directly contacting the cage bottom bedding.

[0038] Then: The air circulation system of the breeding rack drives external air into the placement box through the air inlet pipe, and then flows into the filter element through the connecting port on the top of the mounting shell. The air purified by the filter element flows downward to the bottom of the mounting shell and is discharged into the air circulation system of the breeding rack through the air outlet pipe. The mounting shell is removed periodically by magnetic attraction to replace the filter element, or the pull-out box is pulled out to clean the drinking water residue. All operations do not require complete separation of the cage and the cover, which improves the efficiency of the experiment.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
