Abstract
Description
Technical Field
[0001] The utility model belongs to the field of external delivery thermal insulation boxes, and in particular relates to an active heating thermal insulation box. Background Art
[0002] As the pace of modern life continues to accelerate, food delivery services have become an indispensable part of urban life. The booming development of this industry has not only driven the diversification of the catering industry, but also put forward higher requirements for the delivery process, especially the increasing demand for food insulation and quality preservation. Traditional delivery methods often rely on simple packaging, which is difficult to effectively cope with the insulation challenges of long-distance delivery or severe weather conditions, resulting in food cooling, taste degradation and even food safety issues.
[0003] Most of the mainstream delivery insulation boxes on the market currently use passive insulation technology. The principle is to set up multiple layers of insulation materials inside the insulation box, such as polyurethane foam (EPS), expanded polypropylene (EPP) or other high-performance insulation layers, to block the influence of the external environment temperature on the food in the box, so as to achieve the purpose of insulation and freshness. However, this type of insulation box has obvious limitations: delivery personnel need to frequently open the insulation box to take out or put in food, and the heat accumulated in the box will quickly dissipate, resulting in a significant reduction in the insulation effect. Especially in high-frequency delivery scenarios, after each delivery task is completed, the insulation box must re-store heat, which not only increases energy consumption, but also makes it difficult to ensure the temperature stability of subsequent meals. In addition, the performance of the insulation material gradually decays over time, which will also affect the long-term insulation effect, and thus affect the consumer experience.
[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0027] An active heating insulated box includes a box body 10, a support plate 20 is installed inside the box body 10, and through holes 21 are evenly distributed on the support plate 20. The design of the through holes 21 ensures the natural convection of air and heat, and also promotes the uniform distribution of heat energy, which is conducive to maintaining a constant and suitable temperature environment. The support plate 20 divides the cavity inside the box body 10 into a placement cavity located above the box body 10 and a heating cavity located at the bottom 13 of the box body 10. The box body 10 includes a top 11, a side 12 and a bottom 13, and the heating cavity is located at the bottom 13; the heating cavity is used to place a heating pack 30. The heating pack 30 adopts chemical heat release and can spontaneously generate a continuous supply of heat energy without an external power supply. Compared with the prior art, the utility model can implement active and active heat energy replenishment to the cavity inside the box body 10, thereby greatly enhancing the heat insulation and warming performance of the insulated box.
[0028] Furthermore, the top 11 and the side 12, and the side 12 and the bottom 13 are connected and assembled by a second connecting member 14, and the second connecting member 14 is a zipper or a buckle. Using a zipper or a buckle as a connecting medium can effectively isolate the influence of the external environment, greatly enhancing the operability and convenience of the product. Users can easily open and close according to actual needs and quickly access internal items.
[0029] Furthermore, the heating pack 30 is wrapped with a water-absorbing layer 31 made of a material such as a sponge. The design of the water-absorbing layer 31 can ensure that water molecules diffuse quickly and evenly to each active reaction area in the heating pack 30, making the chemical exothermic reaction more sufficient and efficient. It can also effectively control the water penetration rate to avoid the reaction runaway caused by too fast or too slow water penetration, thereby ensuring the chemical reaction proceeds smoothly, improving the safety during use, and reducing the potential risk of thermal runaway.
[0030] refer to Figure 1 and Figure 2 As an embodiment of the utility model, the bottom 13 is covered with hard plastic, and the side surface of the bottom 13 facing the heating chamber is provided with a heat-insulating layer. The upper edge of the support plate 20 is provided with a welt 22 that fits the inner wall of the box body 10, and the welt 22 is equipped with a plurality of first connecting members 23 for fixing the support plate 20 to the box body 10. This design utilizes the bottom 13 to support the heating pack 30, and the design of the bottom 13 being covered with hard plastic not only provides a solid support foundation for the heating chamber, effectively bears the heat and pressure generated by the heating pack 30 during operation, but also enhances the pressure resistance and wear resistance of the entire device, prolongs the service life of the product, and facilitates the replacement of the heating pack 30.
[0031] refer to Figure 3 and Figure 4 As another embodiment of the utility model, a hard tray 40 is placed in the heating chamber at the bottom 13, and the heating pack 30 is placed on the tray 40. The area of the support plate 20 is larger than the tray 40, so that the support plate 20 can be placed on the edge of the tray 40. The edge design of the tray 40 allows the support plate 20 to be easily placed. When checking or replacing the heating pack 30, the user does not need to directly touch the heating pack 30 or the inside of the heating chamber, which increases the safety of the operation. In addition, the user can directly take the support plate 20 and visually check the working status of the heating pack 30 (such as color changes, whether it is completely reacted, etc.), which is conducive to timely understanding of the heating progress, improving the convenience of use and the user's sense of control over the heating process.
