Description

Technical Field

[0001] This utility model relates to a thermos cup, and more particularly to a thermos cup with good heat preservation effect. Background Technology

[0002] Thermos flasks, widely used in daily life, primarily function to suppress heat loss through conduction, convection, and radiation, thus maintaining the temperature of the liquid inside. Currently, the most mature and widely used thermos flasks typically employ a vacuum double-layer structure. This involves creating a sealed space between the inner liner and the outer shell, eliminating air through vacuuming to achieve dual isolation from convection and conduction, and coating the inner wall or the inside of the vacuum chamber with a reflective film to reduce radiative heat loss. This design can maintain a high level of heat retention for 6–12 hours or more at room temperature. While the vacuum double-layer structure offers superior performance, its high manufacturing cost, stringent equipment requirements, and complex processes contribute to its high production costs. Therefore, there is an urgent need for a new heat retention structure that eliminates the need for large-scale vacuum equipment, simplifies the manufacturing process, and achieves both high heat retention, a simple structure, and low production costs.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figures 1-3As shown, this utility model discloses a thermos cup with good heat preservation effect, comprising: a cup body 1 and a cup lid 6. A heat-insulating connector 4 is provided between the inner liner 2 and the outer shell 3 of the cup body 1. The heat-insulating connector 4 connects the inner liner 2 and the outer shell 3 through a snap-fit ​​to form a cavity structure. The heat-insulating connector 4 is provided with an inner gasket 43, which is located between the upper end face of the inner liner 2 and the lower end face of the outer shell 3, playing a sealing and buffering role, and further reducing heat conduction between the inner liner 2 and the outer shell 3, thereby improving the overall heat preservation performance. The cavity between the inner liner 2 and the outer shell 3 is filled with aerogel 5 to enhance the heat preservation performance. Aerogel is a nanomaterial with extremely low thermal conductivity, which can effectively block heat conduction and convection. Compared with the traditional vacuum layer structure, aerogel not only has similar or even better heat preservation performance, but can also be achieved without vacuuming and high-precision welding, thereby significantly reducing manufacturing difficulty and cost, and improving the structural reliability and applicability of the product.

[0020] The heat insulation connector 4 is provided with a snap fastener 42 facing downwards, and the outer wall of the inner liner 2 is provided with a snap fastener 21 facing upwards. The snap fastener 21 engages with the snap fastener 42 to achieve the engagement between the heat insulation connector 4 and the inner liner 2.

[0021] The thermal insulation connector 4 is provided with a third snap fastener 41, which faces upwards. The inner wall of the outer shell 3 is provided with a second snap fastener 31, which faces downwards. The second snap fastener 31 and the third snap fastener 41 are engaged. This achieves the engagement between the thermal insulation connector 4 and the outer shell 3.

[0022] The above structural design enables rapid assembly between the inner liner 2 and the outer shell 3, eliminating the need for traditional welding or threaded connections, improving assembly efficiency, and reducing production costs.

[0023] This invention provides a thermos cup that is simple in structure, easy to assemble, and has excellent heat preservation performance by combining the heat insulation connector 4 with the snap-fit ​​structure and the aerogel 5 filling. It solves the problems of existing thermos cups that rely on vacuum structure, have high production costs, and have complex manufacturing processes.

[0024] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
