In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1, 2 and 3, in some embodiments, the present application provides a heating assembly 10 that may be used to mount to a surface or interior of a heater blanket 20. Wherein, heating element 10 includes fixed layer 12 and zone of heating 11, and fixed layer 12 is located to zone of heating 11. The heating layer 11 includes a plurality of heating regions 111 and hollow regions 112, and one hollow region 112 is disposed between any two adjacent heating regions 111. Among them, the fixing layer 12 may be a tarpaulin, which has excellent insulating property and heat resistance. The heating layer 11 may be a graphene film prepared by using graphene, conductive carbon black, a polymer binder, and the like as raw materials, and performing pulping, coating, drying, and cutting. As a novel nano material, graphene has excellent electrical conductivity, thermal conductivity and mechanical properties, has feasibility of being applied to the heating blanket 20, and can promote upgrading and upgrading of the existing heating blanket 20 industry.

Above-mentioned heating element 10 because heating element 10's zone of heating 11 carries out the fretwork design for all there is a fretwork region 112 between per two zones of heating 111, and the produced heat of zone of heating 111 alright with spreading to fretwork region 112, thereby makes thermal conduction more even, has avoided the heat of zone of heating 11 central part too to concentrate and lead to the high temperature, and then prevents that the user from being scalded in the use. It can also be considered that, under the condition that the effective heating area of the heating layer 11 is not changed, the arrangement of the hollow area 112 makes the heating area 111 of the heating layer 11 more dispersed, and can cover a larger area, i.e. the diffusion area of heat is enlarged, the heating efficiency is improved, and the uniformity of heat transfer is ensured.

It is understood that the structure of the hollow-out region 112 may be a complete gap structure, i.e., one hollow-out region 112 separates two heating regions 111; the structure of the hollow area 112 can also be regarded as a pattern generated by hollowing in a certain area of the heating layer 11, such as a hollowed pattern or a plurality of evenly distributed small holes, that is, the heating areas 111 can be connected to each other, which aims to effectively diffuse heat generated by the heating area 111 of the heating layer 11 to the hollow area 112 to achieve uniform heat transfer.

Specifically, as shown in fig. 1, in some embodiments, heating layer 11 made of graphene film includes a plurality of heating regions 111 having a rectangular shape. The plurality of heating regions 111 are disposed in parallel along the length extending direction D1 of the heating regions, and the plurality of heating regions 111 are disposed at intervals along the width extending direction D2 to form the hollow region 112, i.e. in such an embodiment, the hollow region 112 can be regarded as a gap between two heating regions 111. More specifically, in some embodiments, the distance between any two adjacent heating regions 111 is equal, that is, the width of each hollow-out region 112 is equal.

Referring to fig. 1, in some embodiments, the heating assembly 10 further includes a conductive sheet 13 disposed on the fixing layer 12, the conductive sheet 13 may be a PI copper foil, and includes a substantially U-shaped positive electrode 131 and a substantially U-shaped negative electrode 132, and the heating layer 11 is electrically connected to an external power source through the conductive sheet 13.

In some embodiments, the heating assembly 10 further includes an adhesive layer, which may be a TPU hot melt adhesive film, and the fixing layer 12 is fixed to the heating layer 11 through the adhesive layer.

Furthermore, as shown in fig. 3 and 4, the present application also relates to a heating blanket 20, which comprises a body 21 of the heating blanket 20 and the heating assembly 10 of any of the above embodiments, wherein the heating assembly 10 is disposed in the body 21 of the heating blanket 20. Because the heating layer 11 of the heating assembly 10 inside the heating blanket 20 is designed to be hollowed, a hollowed area 112 is arranged between every two heating areas 111, and the heat generated by the heating areas 111 can be diffused to the hollowed area 112, so that the heat conduction is more uniform, the phenomenon that the temperature is too high due to too concentrated heat of the central part of the heating layer 11 is avoided, and the user is prevented from being scalded in the using process. It can also be considered that, under the condition that the effective heating area of the heating layer 11 is not changed, the arrangement of the hollow area 112 makes the heating area 111 of the heating layer 11 more dispersed, and can cover a larger area, i.e. the diffusion area of heat is enlarged, the heating efficiency is improved, and the uniformity of heat transfer is ensured.

Specifically, as shown in fig. 2, in some embodiments, the heating blanket 20 may be a single heating blanket 20, i.e., one heating blanket 20 for use by only a single person. The heating assembly 10 of the heating blanket 20 of such an embodiment includes a first heating assembly 101, a second heating assembly 102, and a third heating assembly 103, and the first heating assembly 101, the second heating assembly 102, and the third heating assembly 103 are arranged at intervals in a "three" shape along the length direction of the body 21 of the heating blanket 20. When the user covers the single heating blanket 20 on the back of the human body, the first heating component 101, the second heating component 102 and the third heating component 103 can heat the neck, the waist and the legs of the human body in sequence, so that the design is more humanized, and the user has better hot compress experience.

As shown in fig. 3, in some embodiments, the heater blanket 20 may also be a double heater blanket 20, i.e., one heater blanket 20 may be used by two individuals at a time. The body 21 of the heating blanket 20 of this embodiment is substantially rectangular, the heating elements 10 therein further include a fourth heating element 104, a fifth heating element 105 and a sixth heating element 106, the fourth heating element 104, the fifth heating element 105 and the sixth heating element 106 are arranged in an axisymmetric manner with the first heating element 101, the second heating element 102 and the third heating element 103 by taking a central axis of the body 21 of the heating blanket 20 as a symmetry axis, and the fourth heating element 104, the fifth heating element 105 and the sixth heating element 106 can also be used for corresponding to the neck, the leg and the waist of the human body. Such a configuration may be desirable for use by two persons at the same time, and may be considered a double blanket 20.

Further, as shown in fig. 2 and 3, a wire harness 22 electrically connected to the conductive sheet 13 of the heating assembly 10 is disposed inside the heating blanket 20, and the wire harness 22 is concentrated on the edge of the heating blanket 20. Such a structural arrangement may prevent a user from directly lying on the wire harness 22, reducing the feeling of foreign matter, and improving comfort when the user lies on the heater blanket 20 during actual use.
