AI Technical Summary

Technical Problem

In the limited space of hamster cages, existing hamster nests are difficult to keep warm in winter, ventilate in summer, have clear functional zoning, and be easy to disassemble and clean, resulting in limited activity areas for hamsters and cross-contamination.

Method used

A hamster nest with two layers was designed, including a base shell, an upper hemispherical shell, an external spiral ramp, a side sandpit, and a top food bowl. It adopts a slot-pin structure to achieve quick assembly and disassembly, forming a lower cave that is warm in winter and an upper resting area that is ventilated in summer. The feeding area is physically separated from the sand bath and excretion area to avoid the water bottle taking up internal space.

Benefits of technology

It achieves both winter warmth and summer ventilation within the same volume, provides a three-dimensional movement path, ensures hygienic isolation, reduces cross-contamination, and has a compact structure that facilitates disassembly, cleaning, and maintenance.

Abstract

The utility model discloses a vertically-layered season-adaptive detachable hamster nest. The vertically-layered season-adaptive detachable hamster nest comprises a base shell, an upper-layer hemispherical shell, an upper-layer floor, an internal stair, an external spiral ramp, a side platform, a lateral sandpit and a top dinner basin. The base shell is of a cavity structure, an arch-shaped inlet and outlet is formed in the lower portion, and wood chips or paper scraps can be selectively filled. The upper-layer hemispherical shell is connected with the base shell, and the inner space is divided into an upper layer and a lower layer by the bottom upper-layer floor; the inner staircase is communicated with the lower-layer latent area and the upper-layer floor The external spiral ramp spirals to the side platform along the outer wall of the base shell; a lateral sand pit fixed on the side wall of the base shell is used for sand bath and discharge; and the top dinner basin is arranged at the top of the upper-layer hemispherical shell. The outer wall of the upper-layer hemispherical shell is provided with a ventilation window, and the outer wall treading and grabbing strips are used for the hamster to climb. Warm keeping, ventilation and multifunctional partitioning are achieved in the limited size, and the mouse cage can be detached and washed without tools and is suitable for the mouse cage environment with the limited space.
