In the electric blanket, a heating element is arranged on a base cloth, a power cord is connected, and the sewn heating element and the base cloth are sewn by a mask.
Disclosure of Invention
In view of the above problems, the present invention provides a comfortable electric blanket, which has a soft and comfortable surface, generates heat uniformly, and has good overall comfort.
The technical scheme adopted by the invention for realizing the technical purpose is as follows: the comfortable electric blanket comprises a heat-resistant layer, a heating layer and a heat-insulating layer; the heat-resistant layer, the heating layer and the heat insulating layer are fixedly connected in sequence from top to bottom; the heating layer is a plane sealing bag, a high-temperature-resistant water absorption film is sealed in the heating layer, electric heating wires are uniformly distributed on the water absorption film, a water body is sealed in the heating layer, and the water body is uniformly adsorbed by the water absorption film at normal temperature and does not flow in the heating layer; the electric heating wire is electrically connected to an external power line through a temperature control switch arranged in the heating layer, the temperature control switch is kept disconnected when the temperature in the heating layer exceeds 110 ℃, and otherwise, the temperature control switch is kept connected; when the temperature in the heating layer is 110 ℃, the temperature of the upper surface of the heat resistant layer is 35-50 ℃.
Preferably, the heat-resistant layer comprises a memory sponge layer, the internal pores of the memory sponge layer form diffusion barrier to high temperature, the larger the thickness of the sponge layer is, the better the heat-resistant performance is, heat can be accumulated in the pore structure for a longer time and can be uniformly and slowly released to the upper surface, and heat energy can be effectively saved; according to the specific type or variety of the memory sponge, the proper thickness is selected, so that the requirement that the temperature of the upper surface of the heat-resistant layer is 35-50 ℃ when the temperature in the heating layer is 110 ℃ can be met. Further, the heat-resistant layer further comprises a plastic plate arranged on the lower surface of the memory sponge layer, so that the heating layer is compressed downwards integrally after being pressed by a human body in an expansion state, uneven depression of each part is avoided, and comfort is further improved.
The invention has the beneficial effects that: when the comfortable electric blanket is not heated, a small amount of water in the heating layer is adsorbed in the water absorption film, the water absorption film basically does not occupy the volume, so that the heating layer is kept to be thin, and the electric blanket is convenient to store; when the electric heating blanket is used for heating, the electric heating wire on the water absorption film directly heats a small amount of water uniformly distributed in the water absorption film, so that the water can be quickly vaporized, the heating layer is upwards expanded, the electric heating wire is far away from a human body, and the whole electric heating blanket is uniform and soft; after the high temperature in the heating layer passes through the heat-resistant layer, the low temperature suitable for the human body is formed, so that the human body is warm and comfortable.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1-3, the comfort electric blanket comprises a heat-resistant layer 1, a heating layer 2, and an insulating layer 3; the heat-resistant layer 1, the heating layer 2 and the heat-insulating layer 3 are fixedly connected from top to bottom in sequence; the heating layer 2 is a plane sealing bag, a layer of high-temperature-resistant water absorption film 22 is sealed in the heating layer 2, electric heating wires 21 are uniformly distributed on the water absorption film 22, a water body is sealed in the heating layer 2, and the water body is uniformly adsorbed by the water absorption film 22 at normal temperature and does not flow in the heating layer; the heating wire 21 is electrically connected to an external power line (not shown) through a temperature control switch 23 arranged inside the heating layer 2, and the temperature control switch 23 is kept off when the temperature inside the heating layer 2 exceeds 110 ℃, or kept on otherwise; when the temperature in the heating layer 2 is 110 ℃, the temperature of the upper surface of the heat resistant layer 1 is 35-50 ℃.
After the comfortable electric blanket is electrified, the electric heating wire 21 rapidly heats a small amount of water uniformly distributed in the water absorption film 22, so that the water is rapidly evaporated and fills the whole heating layer 2, the heating layer 2 is expanded into an elastic air bag, the water vapor in a high-temperature state uniformly transfers heat to the heat-resistant layer 1, and after the heat is resistant by the heat-resistant layer 1, a lower temperature suitable for a human body is formed, so that the human body is warm and comfortable.
In addition, when the internal temperature of the heating layer 2 reaches 110 ℃, the temperature control switch 23 is automatically switched off, and the heating wire 21 is switched off to stop heating, so that the danger caused by overhigh temperature of the heating layer 2 is prevented. The high-temperature-resistant water absorption film 22 has the function of relatively uniformly distributing a small amount of water in the heating layer 2 and the heating wire 21, and avoiding local dry burning in the process of heating water by the heating wire 21. This achieves rapid heating and evaporation of a small amount of water over a wide range of the heating wires 21 distributed over a large area (even in the case of a curved electric blanket).
In the comfortable electric blanket, the heat-resistant layer 1 comprises the memory sponge layer, the internal pores of the memory sponge layer form diffusion barrier to high temperature, the larger the thickness of the sponge layer is, the better the heat-resistant performance is, heat can be accumulated in the pore structure for a longer time and can be uniformly and slowly released to the upper surface, and the heat energy can be effectively saved; according to the specific type or variety of the memory sponge, the appropriate thickness is selected, so that the requirement that the temperature of the upper surface of the heat-resistant layer 1 is 35-50 ℃ when the temperature in the heating layer 2 is 110 ℃ can be met. The heat-resistant layer 1 can also comprise a plastic plate arranged on the lower surface of the memory sponge layer, so that the heating layer is compressed downwards integrally after being pressed by a human body in an expansion state, and uneven depression of each part is avoided; the heating layer 2 can be made of elastic materials, the heating layer 2 is expanded by water vapor generated by the heating wire 21 in the heating process, so that the whole electric blanket is rich in elasticity, the comfort of the electric blanket can be improved by using the elastic materials, the safety of the electric blanket can be improved, and the excessive expansion and breakage of the heating layer 2 caused by excessive water vapor generation are avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
