Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermos cup sleeve technology, specifically a self-heating thermos. Background Technology
[0002] Self-heating thermal pads are products that generate heat on their own to provide warmth. They mainly utilize the principle of converting chemical energy into heat energy. When the packaging is torn open, the iron powder in the thermal pad comes into contact with oxygen in the air, and an oxidation reaction occurs. This oxidation-reduction reaction is exothermic, thus generating heat.
[0003] Existing heat insulation patches require users to tear off the outer sealing strip by hand during use, allowing the heating material to come into contact with the outside air and undergo a chemical reaction. However, some sealing strips may have defects after production, making the tearing process cumbersome. Therefore, we have proposed a self-heating heat insulation patch. Utility Model Content
[0004] The purpose of this utility model is to provide a self-heating insulation patch to solve the problem mentioned in the background art that existing insulation patches require users to tear open the outer sealing strip by hand during use, so that the heating material can come into contact with the outside air and undergo a chemical reaction. However, some sealing strips may have certain defects after production, making the tearing process troublesome. To achieve the above objectives, this utility model provides the following technical solution: a self-heating insulation patch, comprising an outer shell, an inner shell movably connected to the inside of the outer shell via a sleeve, two sealing strips movably connected to the side surface of the outer shell, two closed mesh layers fixedly connected to the inside of the outer shell, two heating layers fixedly connected to the inside of the inner shell, and an annular sleeve pad fixedly connected to the top of the outer shell. Each sealing strip has a Velcro closure movably connected to its side surface. The heat is sufficient to maintain the liquid temperature for a considerable period, and it is easy to handle without injuring the hand, thus protecting the user. The temperature gradually rises and heat is transferred to the liquid by tearing off the sealing strip. It is also lightweight and does not add excessive weight. The structure also includes Velcro, allowing the strip to be easily removed.
[0005] In a further preferred embodiment, the two sealing strips are symmetrically distributed on the side surface of the outer shell, and the two sealing mesh layers are symmetrically distributed inside the outer shell. The innermost layer is the heating material, which is wrapped with the material to prevent the material from overflowing. The next innermost layer is the sealing mesh layer, which fixes the heating material to prevent frequent replacement of heating points due to external shaking, thus maintaining continuous heating. The gaps in the next outermost layer can be filled with inert gas to prevent air from entering and to prevent the heating material from prematurely contacting oxygen and losing heat. The outermost layer is the sealing strip, which ensures that no oxygen enters and that the heating material remains stable and does not react. The sealing strip can be transparent or opaque, and text editing such as printing can be done on the sealing strip.
[0006] In a further preferred embodiment, the two sealing mesh layers correspond one-to-one with the two sealing strips. The overall outer shell is made of a high-temperature resistant or temperature-maintaining material. The part of the heating element that contacts the cup body is made of a heat-conducting, high-temperature resistant, and non-flammable material to facilitate heat transfer. The sealing strips provide good sealing after application but will not damage the outer shell when removed, and can be completely removed in one go.
[0007] In a further preferred embodiment, the two heating layers are symmetrically distributed inside the inner shell, and the two heating layers correspond one-to-one with the two sealing mesh layers and the two sealing strips. The overall thickness is designed according to the effect and efficiency of the heating material and the heat preservation time. If the commonly available heating materials are used as a basis, the thickness is 3 to 5 mm.
[0008] In a further preferred embodiment, the two sealing strips are movably connected to the side surface of the outer shell via Velcro. When the sealing strips are torn open and come into contact with air, a chemical reaction occurs, generating heat. This heat can be maintained at 60 to 55°C, but when transferred to the liquid, it can only maintain the liquid temperature at around 45°C.
[0009] More preferably, the heating layer is a heating material suitable for structures such as mineral water and milk tea cups that can conduct heat, such as plastics. It is also suitable as long as the cup contains a heat-conducting liquid and the thickness of the cup does not exceed 2mm. In addition to liquids that can be heated, colloids can also be heated, such as silicone products.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] In this invention, the heat is sufficient to maintain the liquid temperature for a long time without dropping, and it can be handled with one hand without injuring the hand, thus protecting the user. The temperature gradually rises and transfers heat to the liquid as soon as the sealing strip is torn off. At the same time, it is lightweight and does not add too much weight. The structure also has Velcro, which can be used to easily tear off the sealing strip. Attached Figure Description

This material wraps around the heating material to prevent it from spilling out. The next innermost layer is a sealed mesh layer 4, which secures the heating material and prevents frequent changes in the heating point due to external movement, ensuring continuous heating. The gaps in the next outermost layer can be filled with inert gas to prevent air from entering and to prevent the heating material from prematurely contacting oxygen and losing heat. The outermost layer is a sealing strip 3, designed to prevent oxygen from entering and ensure the heating material remains stable and does not react. The strip can be transparent or opaque, and text can be printed on it. The outer shell 1 is made of a high-temperature resistant or temperature-maintaining material. The part of the heating element that contacts the cup is made of a heat-conducting, high-temperature resistant, and non-flammable material to facilitate heat transfer. The sealing strip 3 provides a good seal after application but will not damage the inner shell 2 when removed. It can be completely removed in one go. The overall thickness is designed based on the effect and efficiency of the heating material and the desired heat preservation time. If based on commonly available heating materials, the thickness is 3-5mm.
