Description

Technical Field

[0001] The present invention relates to the technical field of experimental animal breeding equipment, and particularly to a gas supply device for experimental animal breeding equipment. Background Art

[0002] The gas supply device for experimental animal breeding equipment is an important device for maintaining the living environment of experimental animals. Its main function is to provide fresh and constant air supply to the breeding box or laboratory, ensuring that the air quality meets the standards and requirements of animal experiments. The gas supply device can effectively reduce the stress response of experimental animals and improve the accuracy and repeatability of experimental data. In the fields of scientific research and biomedicine, the health and welfare of experimental animals are crucial. The design and use of the gas supply device not only relate to the living quality of experimental animals but also directly affect the reliability and scientific nature of research results. Therefore, the application of the gas supply device is of great significance for ensuring the success and ethics of experimental animal research.

[0003] After retrieval, the patent with Chinese Patent No. CN220458243U discloses a gas supply device for experimental animal breeding equipment, including a housing. A housing cover is installed at the upper end of the housing. An air inlet hole is opened on the upper surface of the housing cover. An air delivery pipe is detachably installed at the upper end of the air inlet hole. The air delivery pipe is connected to an external air transmission fan. The air delivery pipe is used to convey oxygen into the housing. A pressure detection sensor is installed on one side of the inner wall of the housing. The housing and the housing cover form a sealed structure through a buckle. A pressure alarm is fixedly installed on the outer side surface of one side of the housing. When the pressure detection sensor electrically connected to the pressure alarm detects that the internal pressure of the housing is too low, the pressure alarm will issue an alarm to remind the operator to come forward to check. By setting a transmission fan switch, when the pressure alarm issues an alarm, the operator can turn on the transmission fan switch to make the external-connected air transmission fan work to convey air into the housing to achieve the effect of ensuring the stability of the internal pressure of the housing. Compared with the prior art, the patent with Chinese Patent No. CN220458243U can solve the problem that although some old-fashioned experimental animal breeding gas supply devices can supply sufficient gas volume to a great extent, they may also experience the situation of the gas supply device malfunctioning and short-circuiting, resulting in poor air circulation inside the breeding chamber and the death of experimental animals.

[0004] However, in the actual use process of the above device, the gas supply pipeline lacks filtration of the incoming gas when introducing external air, making it difficult to ensure the safety of the incoming gas. Moreover, the gases discharged by the experimental animals themselves during their life in the housing and the turbid gases generated by feces will accumulate at the bottom of the housing, affecting the health of experimental organisms. Therefore, a gas supply device for experimental animal breeding equipment is proposed. Summary of the Invention
