Description

Technical Field

[0001] This utility model relates to the field of small rodent pet supplies, and in particular to a hamster nest with upper and lower layers, an integrated sand bath area, and a tool-free disassembly structure. Background Technology

[0002] Domestic hamsters originate from arid or semi-arid grassland-desert regions such as Syria and Mongolia, with an optimal temperature range of 18℃-24℃. Their natural habits include nocturnal activity, solitary burrowing, food hoarding, and sand bathing. They are highly sensitive to light, sound, temperature, and humidity. Typical household hamster cages have limited space, often less than 0.25 m². Simply stacking hiding, feeding, sand bathing, and digging areas restricts the hamster's activity area and leads to cross-contamination. While patent CN209089647U increases aesthetic appeal, it significantly reduces usable space; patent CN215302221U integrates feeding, watering, and hiding areas, but food is easily mixed with stuffing and excrement, and the water bottle takes up space and is prone to leakage.

[0003] Existing enclosed cages provide good insulation in winter but are prone to becoming hot and oxygen-deficient in summer. Adding separate "cooling nests" would further encroach on the space inside the cage. Therefore, achieving adaptability to both winter and summer temperatures, hygienic isolation, three-dimensional movement, and easy disassembly and cleaning within a limited space has become a pressing technical problem to be solved in this field. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a hamster nest that can simultaneously achieve winter warmth, summer ventilation and cooling, clear functional zoning, and easy disassembly, cleaning and maintenance within a limited cage space.

[0005] This utility model of a hamster cage includes a base shell, an upper hemispherical shell, an external spiral ramp, a side sandpit, and a top-mounted food bowl. The base shell is hollow and can be filled with insulating fillers such as wood chips or paper scraps, or it can be entirely buried within the cage's filler layer, with only the upper floor exposed. The upper hemispherical shell and the base shell are manually assembled using opposing slots and pins to form a layered structure. The outer wall of the upper hemispherical shell has scratching strips for the hamster to climb on. The external spiral ramp winds along the outer wall of the base shell and connects to the side platform. The side sandpit is directly fixed to the side wall of the base shell, providing a sand bath and excretion space for the hamster, and can be partially buried within the filler layer along with the base. The top-mounted food bowl is located at the top of the upper hemispherical shell at the end of the ramp, adjacent to the side platform. This utility model does not have a built-in water bottle location; instead, it provides space for an external water dispenser mounted on the cage wall, avoiding the need for internal space and preventing water leakage and contamination.

[0006] The base shell has an arched entrance at the bottom, allowing hamsters to enter the lower hiding area. The outer wall of the upper hemispherical shell is evenly distributed with ventilation windows, which can be star-shaped or crescent-shaped. Insertion slots are evenly distributed on the inner wall of the base shell, and pins are set at the bottom edge of the upper hemispherical shell. The external spiral ramp has a spiral angle between 180 degrees and 300 degrees to meet climbing needs and save internal space.

[0007] The side sand pit is integrally molded or bonded to the base shell. The upper edge of the sand pit is higher than the surface of the lower filling material to prevent sand backflow. The top-mounted feeding trough is detachable for easy cleaning and replenishment of feed.

[0008] Using the above technical solution, a lower cave that keeps the cage warm in winter and an upper resting area that is ventilated in summer are formed within the same volume. The feeding area and the sand bath and excretion area are physically separated. The external spiral ramp and the stepping strips provide a three-dimensional movement route. The plug-in slot-pin structure can be quickly assembled and disassembled without tools. The overall structure is compact and is especially suitable for rat cage applications with limited space.

Detailed Implementation

[0017] The following is combined Figure 1 — Figure 5The present invention will be further illustrated by the embodiments. Those skilled in the art can make various modifications to the embodiments without departing from the spirit and scope of the present invention. The drawings and descriptions are illustrative in nature and not limiting.

[0018] like Figure 1 — Figure 5 As shown, this utility model hamster nest includes a base shell 1, an upper hemispherical shell 2, an external spiral ramp 3, a lateral sandpit 6, and a top-mounted food bowl 12. The base shell 1 is cylindrical with an internal cavity. Two arched entrances 13 are located at the bottom, each 40 mm wide. The internal cavity is filled with wood chips or paper scraps, or it can be entirely embedded in the cage's filling layer, with only the upper floor 4 exposed to form a warm, concealed space for winter hiding. The internal cavity of the base shell 1 is connected to the upper floor 4 via an internal spiral staircase 14. Several insertion slots 5 are arranged circumferentially on the inner wall of the base shell 1.

[0019] The bottom edge of the upper hemispherical shell 2 is equipped with pins 7, which correspond one-to-one with the insertion slots 5. Assembly can be completed by manually pressing and positioning them. Windows 11 are opened on the outer wall of the upper hemispherical shell 2, and corresponding claw strips 8 are provided on the inner wall for hamsters to climb on. The upper floor 4 divides the internal space into upper and lower levels, which are connected by an internal staircase 14.

[0020] The external spiral ramp 3 starts from the bottom of the side wall of the base shell 1, spirals up along the outer wall to the side platform 10, with a spiral angle of about 240 degrees and a ramp width of 30 mm. The surface is textured with anti-slip material. The end of the ramp is flush with the side platform 10. A removable top-mounted food bowl 12 is placed on the top of the upper hemispherical shell, adjacent to the side platform 10, ensuring a clean and elevated feeding area.

[0021] The side sand pit 6 is directly fixed to the base shell 1 as one piece. The upper edge of the sand pit 6 is higher than the surface of the lower filling material to prevent sand particles from flowing out and can be washed and cleaned along with the base as a whole.

[0022] The main components of this embodiment are formed by 3D printing of polyethylene terephthalate (PETG), but other printing materials or manufacturing methods can also be used. The overall dimensions of this invention can be adjusted according to the type of hamster and the specifications of the cage, and are not limited to the values ​​of 200 mm bottom diameter and 160 mm overall height described in the embodiment.

[0023] With the above structure, the lower filling area forms a relatively closed, heat-insulating cave in winter, while the upper ventilation windows and openings provide a cool and resting space in summer; hamsters can achieve three-dimensional climbing through the external spiral ramp 3 and the outer wall scratching strips 8; the feeding area, sand bath and excretion area and rest area are physically separated to reduce cross-contamination; the plug-in slot-pin structure makes the upper and lower shells quick and easy to disassemble, clean and maintain.

[0024] The above description is merely an exemplary embodiment of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the appended claims and their equivalents.
