<p>The present invention relates to a valve structure of an air supply for a mouse breeding cage. In the valve structure of an air supply for a mouse breeding cage, the valve comprises a nozzle (200) combined to an air supply duct (300), and a cage inner valve (110) detached/attached to the nozzle (200) and formed in a hole on the wall of the cage (100). The nozzle (200) comprises a nozzle fixation unit (210) and a nozzle movement unit (220) moving forward and backward within the nozzle fixation unit (210), wherein the nozzle fixation unit (210) is connected to the air supply duct and consists of a housing (213) having a hole therein, the nozzle movement unit (220) has a cylindrical external shape, a nozzle hole therein, which becomes an air passage, and a coil spring (230) mounted between the nozzle fixation unit (210) and the nozzle movement unit (220). The present invention relates to a valve structure of an air supply for a mouse breeding cage, and has remarkable effects of simple and accurate operation of the valve of an air supply mounted in a mouse breeding case, no malfunction, and a secured air-tight function.</p> |
