[0002] In biomedical research, mice are a commonly used experimental animal model, widely used in drug screening, disease mechanism exploration, and therapeutic efficacy evaluation. Drug administration is a critical step in these experiments, and its accuracy and consistency directly impact the scientific nature and reliability of experimental results.

[0003] The environment in which mice are kept can easily accumulate contaminants such as food scraps, feces, and urine. These contaminants not only create odors but can also breed pathogens such as bacteria and viruses, posing a threat to the mice's health. Regular cleaning can effectively reduce the accumulation of these contaminants and maintain a clean and hygienic environment. A good environment promotes the growth and development of mice, improving their quality of life and welfare.

[0004] Mice require regular cleaning of their enclosures to keep them clean and dry. When there are too many mice in each group, the necessary dismantling of the enclosures for internal disinfection and cleaning is necessary, significantly increasing the workload for researchers. Manual cleaning can also increase stress on the mice, and the need to move them as needed can further increase stress and lead to stress reactions, which can create additional variables in the data.

[0005] Therefore, there is an urgent need for a quantitative drug feeding device for mouse experiments, which can not only feed the mice quantitatively, but also reduce the labor intensity of researchers, facilitate the cleaning of the mouse breeding environment, thereby reducing the stress of the mice and improving the accuracy of the comparative data.

[0008] The box body has a collecting trough placed at the bottom of the box body, a quantitative feeder is symmetrically installed on the inner wall of the box body, and a glass sealing plate is fixedly connected to the top of the box body;

[0009] It also includes a disinfection mechanism that slides horizontally on the inner wall of the box, including a bottom plate, holes are evenly opened in the middle of the bottom plate, sliding openings are opened on both sides of the bottom plate, an L-plate is slidably connected in the sliding opening, and the top of the L-plate is fixedly connected to the shell, and a disinfection component is arranged in the shell;

[0010] The adsorption mechanism is connected to the bottom end of the L-plate and is movable at the bottom of the base plate. It includes two groups of symmetrically arranged guide boxes, and the middle parts of the two adjacent guide boxes are fixedly connected with inclined plates. The guide boxes and the inclined plates are both inclined toward the middle parts, and the middle parts of the two groups of guide boxes are symmetrically connected with drive components.

[0011] Through the above technical solution, the glass sealing plate on the top is used to achieve a semi-closed state inside, which is convenient for observation and prevents mice from escaping; the quantitative feeder can feed mice quantitatively, put in medicine mixed with food, and record the mice's intake under observation; the disinfection mechanism can wipe and clean the residues and mouse urine remaining in the bottom plate, and with the cooperation of the replacement mechanism, it can automatically push the baffles on both sides to slide open, and use the grooves to quickly disassemble and replace the disinfection cotton, and move at a uniform speed to reduce the pressure on the mice. When performing disinfection operations, the adsorption mechanism at the bottom can simultaneously absorb the disinfected gas and food residues on the bottom plate, and guide them to the collection trough for convenient unified treatment.

[0019] As a further improvement of the above scheme, the driving assembly includes a positioning plate 2, which is fixedly installed in the middle of one side of the box body. A motor is fixedly connected to the positioning plate 2, and a rotating shaft is fixedly connected to the output shaft of the motor. The outer wall of the rotating shaft is threadedly connected to a sliding block 2, and both ends of the sliding block 2 are fixedly connected to circular protrusions.

[0052] It also includes a disinfection mechanism, which slides horizontally on the inner wall of the box body 1, including a bottom plate 3, with holes evenly opened in the middle of the bottom plate 3, and sliding openings opened on both sides of the bottom plate 3. An L-plate 23 is slidably connected in the sliding opening, and the top of the L-plate 23 is fixedly connected to the shell 16, and a disinfection component is arranged in the shell 16.

[0053] The disinfection component includes a slide 17, which is fixedly connected to the middle of the inner wall of the shell 16, and the bottom end and one side of the shell 16 are both open. A limit plate 18 is slidably connected to the slide 17, and a vertical groove 19 is symmetrically provided in the middle of the limit plate 18. Slide rods 20 are vertically slidably connected in the two groups of vertical grooves 19. The bottom ends of the two groups of slide rods 20 are fixedly connected to disinfection cotton 21, and a spring three 22 is elastically connected between the disinfection cotton 21 and the limit plate 18. A groove is provided on the side of the limit plate 18 that is open to the side, and the bottom end of the disinfection cotton 21 slides against the bottom plate 3.

[0054] It also includes a replacement mechanism, which includes connecting ports 5 symmetrically opened at the bottom of both ends of the box body 1, and vertical slots 6 symmetrically opened on the outer walls of both ends of the box body 1, and springs 7 are fixedly connected in the two groups of vertical slots 6, and sliding blocks 8 are fixedly connected at the bottom ends of the two groups of springs 7, and the sliding blocks 8 slide vertically in the vertical slots 6.

[0055] A horizontal cavity 9 is provided on the outside of the sliding block 8, and a slide plate 10 is horizontally slidably connected in the horizontal cavity 9, the outer end of the slide plate 10 is fixedly connected to a side rod 11, the outer end of the side rod 11 is fixedly connected to a positioning plate 12, and a spring 2 13 is elastically connected between the positioning plate 12 and the sliding block 8, and a cross bar 15 is fixedly connected in the middle of the sliding block 8 on the same side, and a baffle 14 is fixedly connected to the bottom of the two groups of positioning plates 12.

[0056] The side cross-sections of the two sets of baffles 14 are inward-facing triangles, with the bottom ends slidingly abutting against the box body 1, and the inner ends of the baffles 14 slidingly abutting against the top of the shell 16, wherein both sides of the top of the shell 16 are inclined.

[0057] The implementation principle of a quantitative drug feeding device for mouse experiments in the embodiment of the present application is as follows:

[0058] When disinfection and cleaning are required, start the motor 45 to drive the rotating shaft 42. By utilizing the threaded connection between the rotating shaft 42 and the sliding block 2 43, the entire sliding block 2 43 and the adsorption mechanism on both sides and the shell 16 can be started to perform horizontal displacement at the bottom plate 3. During the movement of the shell 16, the two sets of springs 3 22 are used to elastically push the disinfection cotton 21 vertically downward and press it against the top of the bottom plate 3. Under the action of the disinfection cotton 21, the bottom plate 3 can be abutted and wiped to remove internal residues and perform disinfection operations.

[0059] As the shell 16 slides to one end, it pushes the shell 16 and the baffle 14 to slide and abut against each other, pushing the top of the baffle 14 to slide with the inner wall of the box body 1, cooperating with the sliding of the slide plate 10 and the horizontal cavity 9 to slide outward, and synchronously drives the baffle 14 to slide outward, and under the sliding of the bevel of the shell 16 and the baffle 14, it drives the baffle 14 to slide outward and upward, so that the shell 16 moves to the outermost end, so that the sliding block 18 slides vertically in the vertical slot 6 for adaptive sliding, and makes the limit plate 18 open on one side of the shell 16, which can be slid and removed by the groove under the horizontal sliding of the slide bar 17 and the limit plate 18, and can be quickly replaced and cleaned. After reinstallation, when cleaning is required, the motor 45 can be driven in reverse, and when cleaning and disinfecting again, due to the lack of driving force of the baffle 14, it can be returned to its original position and closed under the elasticity of the spring 1 7 and the spring 2 13.
