This invention discloses a continuous mouse-trapping device, belonging to the field of animal trapping technology. The device includes a first housing, a lifting box, a sealing plate assembly, a lifting assembly, a pusher assembly, an active space, a second housing, and a controller. The first housing contains a lifting space with inlets at both ends. The lifting box is slidably disposed within the lifting space and has an internal cavity extending through both ends, having a first position communicating with the inlets and a second position where both ends are closed. The sealing plate assembly is located at the inlets to close them after a mouse enters the internal cavity. The lifting assembly drives the lifting box to move up and down. The pusher assembly is located on the lifting box to push the mouse out of the internal cavity. The active space is adjacent to the lifting space; when the lifting box is in the second position, the internal cavity communicates with the active space. The second housing is located above the first housing and contains a flip-up assembly and a collection cavity. This invention enables automated continuous mouse trapping, improving the success rate of mouse trapping.
