Low-power EVC mouse breeding cage box

Abstract

The invention relates to a negative pressure type EVC mouse breeding cage box, in particular to a low-power EVC mouse breeding cage box. The low-power EVC mouse breeding cage box comprises a box body, a box cover as well as a water and food iron frame placed in the box body; an air inlet and an air outlet are formed on the two opposite side walls of the box body respectively to form a one-way air flow structure in the cage box; the air outlet and the air inlet are not at the same plane height; the air inlet is lower than the air outlet, and the box cover is integrally sealed at the upper part of the side wall of the box body. A filter is respectively mounted on the air outlet and the air inlet. According to the invention, the air inlet and the air outlet are formed on the two opposite side walls of the box body respectively to form the one-way air flow structure in the cage box; the ambient air in the negative pressure type EVC mouse breeding cage box is sucked through a fresh air entering port (air inlet) and is exhausted through the air outlet in the one-way air flow structure manner; since the air inlet and the air outlet are vertically staggered in position, air in the box body flows upwards generally; compared with the prior art, the structure has the advantages that air is exchanged with fresh air thoroughly, so that a better living environment is supplied for mice; and meanwhile, due to the adoption of the fitting method of the filters, not only is the replacement convenient, but also the air filtration effect enables the air quality in the box body to be ensured.

Description

technical field [0001] The invention relates to a negative pressure type EVC mouse breeding cage, in particular to a low-power EVC mouse breeding cage. Background technique [0002] Animal experiments are a necessary means of obtaining scientific data in life sciences. With the continuous development of science and technology and the further deepening of scientific research, the requirements for animal experiment techniques and conditions for animal experiments are getting higher and higher. Raising cages for experimental animals is an important equipment to ensure the feeding, breeding and experiments of specific animals. Raising cages for experimental animals are suitable for the cultivation, reproduction and protection of experimental mice and other animals, especially for raising immunodeficiency experimental mice and cultivating experimental genetic research experimental mice. It is an economical and convenient feeding equipment. Provide high standards of low NH for ex...

AI Technical Summary

Problems solved by technology

[0004] At present, the cages on the market generally have an opening on the top of the lid for ventilation. For example, an air inlet pipe and an exhaust pipe are respectively installed on both sides of the cage lid. The pressure air sent by the fan is sent to the cage by the air supply pipe, and then discharged from the exhaust pipe. At that time, in this configuration, because the mouse feces and the like were located in the lower part, sometimes, the air had not completely reached the bottom before it was discharged from the exhaust pipe. The trachea is discharged, so there is often fresh air in the cage that is not fully utilized, and the residual ratio of ammonia and carbon dioxide gas is relatively large, so that the animals in the cage cannot have a good living environment
