[0002] At present, rats or mice are often used for pharmaceutical experiments in biochemical laboratories. Rats or mice need to go through the process of raising young rats first. During this process, the breeding box is the main space for the survival and development of young rats.

[0003] At present, mice will emit a large amount of unpleasant odors through physiological activities such as defecation and excretion. The traditional ventilation device directly discharges the waste gas to the outside, which is likely to reduce the working comfort of the breeder. In addition, the bedding and feed of mice are very likely to generate dust and block the pipeline, resulting in poor air circulation, excessive generation of harmful substances such as ammonia and hydrogen sulfide, and extremely likely to cause animal death and disease. Only pipeline cleaning can be carried out, but this is difficult to clean, and it is also easy to cause damage, as well as dust accumulation and microbial growth. Therefore, there is an urgent need for an air filtration device for a mouse cage to solve the above problems. Content of the Utility Model

Specific Embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In the embodiment, given by Figures 1-5 There is provided an air filtration device for a mouse cage. The present utility model includes a cabinet body 1 and a mouse cage 14. The back of the cabinet body 1 is fixedly connected with a primary filter box 2. The back of the primary filter box 2 is fixedly connected with a discharge pipe 3. One end of the discharge pipe 3 away from the primary filter box 2 is fixedly connected with a conveying fan 4. The air outlet end of the conveying fan 4 is fixedly connected with an air filter 5. It should be noted that the filtration level of the air filter 5 is F9, which can filter particles with a size of 0.3 - 1 micron to intercept bacteria-carrying particles. The air filter 5 is a conventional known device, so no excessive principle description will be given in the text.

[0029] Specifically, referring to Figure 5, a filter rack 6 is inserted inside the primary filter box 2. A filter net 7 is fixedly connected inside the filter rack 6. A sealing cover 8 is fixedly connected to the top of the filter rack 6. A sliding rod 9 is fixedly connected to the top of the primary filter box 2. A pressing piece 10 is slidably connected to the outside of the sliding rod 9. A fixing block is fixedly connected to the top of the sliding rod 9. A supporting spring 11 is fixedly connected to the bottom of the fixing block. One end of the supporting spring 11 away from the fixing block abuts against the pressing piece 10, and the bottom of the pressing piece 10 abuts against the top of the sealing cover 8.

[0030] In this embodiment, during actual use, the filter net 7 filters particles larger than 0.8 microns. The elastic potential energy of the supporting spring 11 is used to squeeze the pressing piece 10, so that the pressing piece 10 can tightly press the sealing cover 8 to prevent the sealing cover 8 from loosening. By rotating the pressing piece 10 to cancel the abutting state between the pressing piece 10 and the sealing cover 8, the filter rack 6 can be conveniently pulled out for cleaning or replacement, thereby maintaining air circulation.

[0031] Specifically, referring to Figure 3 , a partition is arranged inside the cabinet body 1. The partition divides the space inside the cabinet body 1 into six storage chambers. A sliding seat 12 is fixedly connected to the inner wall of the storage chamber. A sliding block 13 is fixedly connected to the side wall of the mouse cage 14. The sliding block 13 is slidably connected above the sliding seat 12. A first observation window 15 is arranged on the front of the mouse cage 14. A first air port 16 is opened on the front of the mouse cage 14. A taking cover 17 is rotatably connected to the top of the mouse cage 14. A protection plate 20 is rotatably connected to the front of the cabinet body 1. A second observation window 21 is arranged on the front of the protection plate 20. A second air port 22 is opened on the front of the protection plate 20. A handle 23 is fixedly connected to the front of the protection plate 20.

[0032] In this embodiment, during actual use, by arranging the partition, each space is independent, avoiding droplet infection between mice. By arranging the first air port 16, it is convenient for air circulation. By arranging the first observation window 15 and the second observation window 21, it is convenient for experimental personnel to observe the condition of the mice. The second air port 22 arranged on the protection plate 20 intersects with the position of the first air port 16, further blocking the droplets and reducing the possibility of droplet transmission infection.

[0033] It should be noted that a retaining net 18 is arranged at the bottom of the mouse cage 14, and a collection box 19 is arranged on the inner bottom wall of the storage chamber. By arranging the retaining net 18, the excrement of the mice drops into the collection box 19, which can separate the mice from the excrement, reduce the possibility of the mice getting sick, and at the same time facilitate regular cleaning of the excrement.

[0034] Working principle:

[0035] By sliding the slider 13 on the mouse cage 14 above the slide base 12, then closing the protective plate 20, and starting the delivery fan 4 to convey the waste gas discharged by the mouse into the air filter 5. The waste gas first passes through the filter net 7 on the filter rack 6, and the larger impurities in the waste gas are initially filtered by the filter net 7. Then, the air filter 5 efficiently processes the waste gas. When it is necessary to clean the filter net 7, by rotating the abutting piece 10, the abutting state between the abutting piece 10 and the sealing cover 8 is cancelled, so that the filter rack 6 can be conveniently pulled out for cleaning or replacement, thereby maintaining normal air circulation.
