Description

Technical Field

[0001] This invention relates to the field of cooling cup technology, and specifically to a portable cooling cup. Background Technology

[0002] Currently, portable cooling cups on the market that use semiconductor cooling chips to achieve cooling, heat preservation, and refrigeration functions have some shortcomings in their core structural design. These products generally use a screw-in method, where the cooling block and cooling chamber are fixed from the bottom of the lid upwards. This assembly method causes unnecessary trouble in actual production. During assembly, the operator must first place the cooling block and cooling chamber close to their corresponding positions on the inside of the lid, and then manually or with the aid of tools insert the screws into the screw holes on the components from the bottom of the lid. Because the cooling blocks are mostly made of thin metal, they are easily misaligned by the force of the screws being tightened, making it difficult to accurately align the screw holes. This often requires repeated adjustments to the component positions, significantly increasing assembly time and operational difficulty. Especially in mass production scenarios, this directly reduces the overall efficiency of the production line.

[0003] Moreover, this upward-fixed structure lacks stability. The direction of force on the screws is opposite to the direction of the turning force when the lid is opened and closed during daily use. Frequent opening and closing of the lid over a long period of time can cause the screws to gradually loosen, leading to gaps between the cooling block and the cooling chamber. This not only hinders the efficient transfer of cold energy generated by the thermoelectric cooler, weakening the cooling and insulation effects, but may also cause component displacement, further exacerbating structural instability. Subsequent disassembly and reassembly during maintenance also become cumbersome due to the same assembly logic, causing inconvenience in both production and use. Utility Model Content
