The invention relates to an electric blanket.
With the development of society, people have increasingly high requirements for a better quality of life. During cold winters, people commonly adopt electric blankets to maintain warmth when they sleep in places without heating. However, the existing electric blankets generally use metal electric heating wire as the heating material, which requires a relatively higher power supply voltage. The high voltage will cause electric shock in case of leakage, with negative safety performance. Furthermore, the higher voltage requires higher requirements for the power or power supply method.
The invention intends to solve the above problems in the background technology and provide an electric blanket.
To solve the above problems, the invention provides the following technical solution: An electric blanket comprises the electric blanket fabric provided with multiple quilting in interlaced multi-line stitches; the electric blanket fabric is provided with a heating element around the quilting stitches, and the heating element is provided with a coupler for connecting to a controller;
And the heating element consists of a core, an inner conductor, an intermediate layer, an outer conductor, a film layer and an outer jacket from inside to outside.
Preferably, the electric blanket fabric is made of flannel on one side and lambswool on the other.
Preferably, the electric blanket fabric is made of double-sided flannel.
Preferably, the electric blanket fabric is made of double-sided lambswool.
Preferably, the electric blanket fabric is made of double-sided plush.
Preferably, the electric blanket fabric is made of plush on one side and lambswool on the other.
Preferably, the electric blanket fabric is made of PV fleece on one side and lambswool on the other.
Preferably, the electric blanket fabric is made of PV fleece on both sides.
Preferably, the electric blanket fabric is made of back-printed weft-knitted coral fleece on both sides.
Preferably, the core is a polyester thread 1500 D.
Preferably, the inner conductor is made of pure nickel material.
Preferably, the intermediate layer is made of NTC resin.
Preferably, the outer conductor is made of pure copper material.
Preferably, the film layer is made of PET material.
Preferably, the outer jacket is made of PVC compound.
Compared to the prior arts, the invention has the following advantages and beneficial effects: reasonable structural design and excellent heating effects realize a comfortable customer experience of the machine washable blanket, with excellent promotion prospects.
In the description of the disclosure, orientation descriptions if mentioned, for example, orientations or positional relationships as indicated by terms such as ‘center’, ‘vertical’, ‘widthwise’, ‘longitudinal’, ‘width’, ‘thickness’, ‘up’, ‘down’, ‘front’, ‘back’, ‘left’, ‘right’, ‘vertical’, ‘horizontal’, ‘top’, ‘bottom’, ‘inside’, ‘outside’, ‘clockwise’, ‘counterclockwise’, are based on the orientations or positional relationships shown in the drawings, and they are intended for facilitating and simplifying the description of the disclosure only, but not indicating or suggesting that the referred device or element must have such a specific orientation, or be constructed and operated in such a specific orientation, and thus, those orientations or positional relationships shall not be construed as limitations to the disclosure.
In addition, terms such as ‘first’ and ‘second’ are used herein for purposes of description and are not intended to indicate or imply relative importance or significance or to imply the number of indicated technical features. Thus, the feature defined with ‘first’ and ‘second’ may comprise one or more of these features. In the description of the disclosure, ‘a plurality of’ means two or more than two, unless specified otherwise.
It should be noted that unless otherwise specified, if a certain feature is referred to be ‘set’, ‘fixed’, or ‘connected’ to another feature, it can be directly set, fixed, or connected to another feature, or indirectly set, fixed, or connected to another feature. In the description of the embodiments of the invention, if it refers to ‘several’, it means more than one; if it refers to ‘a plurality of’, it means more than two; if it refers to ‘greater than’, ‘less than’, and ‘exceeding’, it should be understood as not including the current number; and if it refers to ‘over’, ‘below’ and ‘within’ should be understood as including the current number. If ‘first’ and ‘second’ are involved, it should be understood as used to distinguish technical features, but cannot be understood to indicate or imply relative importance or implicitly indicate the number of indicated technical features or implicitly indicate the precedence relation of the technical features.
