Description
Technical Field
[0001] The utility model relates to the technical field of electric heating shawls, in particular to an electric heating shawl with good heat preservation effect. Background Art
[0002] An electric shawl is a heating tool that is worn on the shoulders and is similar to an electric blanket. Because it is easy to use, comfortable, and available anytime and anywhere, it is suitable for a wide range of people, including the elderly, children, office workers, and outdoor sports enthusiasts. When reading, watching TV, working in winter, traveling, or engaging in outdoor activities, you can use an electric shawl to keep warm and improve your quality of life.
[0003] The current electric heating shawl is worn on the shoulders of the human body. When the human body moves, a gap will appear between the shawl and the human body, and the flow of air in the gap will cause heat dissipation. In addition, the part of the electric heating shawl itself that contacts the air will also cause more heat dissipation due to heat conduction, resulting in the electric heating shawl not having good thermal insulation performance. Therefore, we propose an electric heating shawl with good thermal insulation effect. Utility Model Content
[0004] The utility model aims to provide an electric heating shawl with good heat preservation effect. The utility model has the function of avoiding a large gap between the human body and the electric heating shawl when the human body is moving, and also limiting the flow of air in the gap, so as to avoid the flowing air taking away heat, and reducing the heat dissipation of the part of the electric heating shawl itself that is in contact with the air, so that the electric heating shawl has the advantage of good heat preservation performance, and solves the problem that when the current electric heating shawl is used on the shoulders of the human body, a gap will appear between the shawl and the human body when the human body is moving, and the flow of air in the gap will cause heat dissipation, and the part of the electric heating shawl itself that is in contact with the air will also cause more heat dissipation due to heat conduction, so that the electric heating shawl does not have good heat preservation performance.

[0009] Preferably, a storage bag is provided on the front surface of the first extended shoulder strap below the USB plug.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] The utility model achieves the effect of avoiding a large gap between the human body and the electric heating shawl when the human body is moving by arranging the electric heating shawl main body, the extended shoulder part, the plush layer, the electric heating wire and the thermal radiation reflecting layer, and also limits the flow of air in the gap, thereby preventing the flowing air from taking away heat, and reducing the dissipation of heat in the part of the electric heating shawl itself that contacts the air, so that the electric heating shawl has a good thermal insulation effect. The extended shoulder strap is draped over the shoulder in use, and the plush layer contacts the human body. The electric heating wire generates heat after being energized, and under the action of the thermal radiation insulation reflecting film, the heat is reflected toward the human body, and plays a role in heat insulation, reducing the heat dissipation of the part of the electric heating shawl main body that contacts the air. At the same time, when the user is moving, due to the presence of the plush layer, the flow of air in the gap between the human body and the electric heating shawl main body is limited, thereby reducing the dissipation of heat, so that the electric heating shawl main body has a good thermal insulation effect.
[0012] The utility model achieves the effect of enabling the electric heating shawl main body and the extended shoulder strap to better contact with the human body and avoiding the occurrence of a movable gap between the two by arranging the first elastic band, the second elastic band, the Velcro thorn surface, the Velcro fleece surface, the locking positioner and the locking fastener, thereby further improving the heat preservation performance of the electric heating shawl main body; the two second elastic bands are connected by the locking positioner and the locking fastener, and the second elastic band and the first elastic band are connected by the Velcro thorn surface and the Velcro fleece surface, so that the electric heating shawl main body and the extended shoulder strap can be better attached to the human body.
[0013] The utility model provides a power supply, a connecting line, a mains plug and a USB plug, so that the heating wire can be powered by the mains or by a mobile power source such as a power bank, thereby improving the applicability and convenience of use. When the heating wire is powered by a mobile power source such as a power bank, the USB plug can be directly connected to the power bank, and when the heating wire is powered by the mains, the mains plug is inserted into the mains socket, and the mains is used to power the heating wire after power conversion.
