It should be noted that the reinforcing rib net 1 may be a base net, a plastic net or a fiber net for producing a carpet, and provides a mounting base for the heating element 5, the first fabric layer 2 and the second fabric layer 3, thereby ensuring the tensile strength of the flexible heating component.
It should be noted that the flexible heating component is a general name of structures such as a household electric blanket and an electric heating pad, and this embodiment is specifically in the field of household electric blankets, but is not limited to the field of household electric blankets.
Can enough provide the installation basis for heating element 5, first precoat 2 and second precoat 3 through setting up strengthening rib net 1, can improve holistic tensile strength again, when first precoat 2 and second precoat 3 chose for use softer longitude and latitude high elasticity or ultra-thin plush, can be with the effect of whole tensile effect on strengthening rib net 1 to make flexible heat-generating component whole still can satisfy the relevant requirement of mechanical strength in national standard GB 4706.8.
Can utilize strengthening rib net 1 to undertake the requirement of the tensile strength of electric blanket through above-mentioned design to can play the effect of support and buffering, reduce the electric blanket tensile deformation that leads to because of external force, the first surface fabric layer 2 that corresponds and the optional various surface fabrics of second surface fabric layer 3 in addition, the surface fabric undertakes the comfortable, pleasing to the eye attribute of bedding, satisfies user's comfort level requirement, has widened the optional scope of first surface fabric layer 2 and the 3 surface fabrics of second surface fabric layer.
Generally, the embodiment of the utility model provides a novel flexible heat-generating component, its scope that can enlarge the precoat and choose for use can enough guarantee user's comfort level, can satisfy the relevant requirement of mechanical strength in the national standard GB4706.8 again.
Specifically, in this embodiment, the heating element 5 is fixed between the second fabric layer 3 and the reinforcing mesh 1.
Further, in order to ensure that the heating element 5 can be stably installed between the second fabric layer 3 and the reinforcing rib net 1, and the situation that two parts of the heating element 5 are contacted with each other due to the displacement of the heating element 5 does not occur in use, in the embodiment, a hot melt adhesive layer 4 is specially added, and the hot melt adhesive layer 4 is arranged between the heating element 5 and the second fabric layer 3; so that the first facing material layer 2 and the second facing material layer 3 are adhesively fixed on both sides of the reinforcing bar net 1, and the heating element 5 is adhesively fixed between the second facing material layer 3 and the reinforcing bar net 1.
Can be through setting up hot melt adhesive layer 4 in second precoat 3 one side to can make heating element 5 directly glue in second precoat 3, and can also utilize hot melt adhesive layer 4, make strengthening rib net 1 and first precoat 2 all bond each other with second precoat 3, thereby make heating element 5 bonding be fixed in between strengthening rib net 1 and second precoat 3.
Through the design, the traditional wiring mode that the heating element can move in the channel can be changed into the bonding and fixing mode, so that the heating element 5 is ensured to be fixed between the reinforcing rib net 1 and the second fabric layer 3, the heating element 5 is ensured not to have a moving space, and the problem of heat accumulation caused by mutual contact of two parts of the heating element 5 due to the displacement of the heating element 5 is effectively prevented; and can utilize hot melt adhesive layer 4 also to adhere strengthening rib net 1 in second precoat 3 to the hole of hot melt adhesive infiltration strengthening rib net 1 bonds first precoat 2 in strengthening rib net 1, thereby has guaranteed the holistic reliability of flexible heat-generating component.
Specifically, in this embodiment, the hot melt adhesive layer 4 is in a fiber mesh shape and is sprayed on one side of the second fabric layer 3. Not only ensures that the hot melt layer can stably bond the heating element 5, but also ensures that the thickness of the hot melt adhesive layer 4 does not influence the whole softness and comfort.
It should be noted that the fiber net shape means that when the hot melt adhesive is sprayed out by a spray head, the fiber net shape is formed on the surface of the second fabric layer 3; the method is different from the traditional method of rolling and coating viscose or spraying in a bead shape to completely cover the bearing surface material layer (the viscose can permeate into the bearing surface material layer in the method, the comfort and the air permeability of the flexible heating part are influenced, the glue consumption is large, and the bonding effect is low).
In the embodiment, the hot melt adhesive is a moisture curing reactive polyurethane hot melt adhesive, and needs to be heated (at a heating temperature of 150-200 ℃) before being sprayed on the second fabric layer 3, so that the hot melt adhesive can be melted and sprayed on the second fabric layer 3, and meanwhile, based on the characteristics of the hot melt adhesive material, the hot melt adhesive can be guaranteed not to be heated and melted again in the use process after the flexible heating component is manufactured; thereby ensuring the reliability of the flexible heating component and prolonging the service life of the flexible heating component.
Further, in order to ensure that the reinforcing mesh 1 is matched with the first fabric layer 2 and the second fabric layer 3 in size, in this embodiment, the area of the reinforcing mesh 1 is the same as the area of the first fabric layer 2 and the second fabric layer 3.
It should be noted that, first precoat 2 and second precoat 3 are made through the size of different beds among the traditional domestic electric blanket, and multiple size is in order to adapt to different consumers' needs, and under this prerequisite, the surface of first precoat 2 and second precoat 3 is the rectangle more, and reinforcing bar net 1 adopts the rectangle with first precoat 2 and second precoat 3 matching this moment.
In this embodiment, heating element 5 is double-deck spiral line that generates heat, and double-deck spiral line arranges according to predetermineeing the route, forms the layer that generates heat with first precoat 2 and the matching of second precoat 3, and the area on the layer that generates heat is less than the area of first precoat 2 or second precoat 3.
It should be noted that the heating wire distributes according to the snakelike among the domestic electric blanket of tradition, encloses synthetic heating wire layer, and the length on heating wire layer is slightly less than the length of first precoat 2 this moment, and the width on heating wire layer is slightly less than the width of first precoat 2, and this is the conventional design in domestic electric blanket field, does not do here and describe repeatedly.
In addition, when the heating cushion is applied to the field of heating cushions and the like, the arrangement route of the heating lines can also adopt various patterns such as circles, but the corresponding circle area of the heating lines is smaller than that of the first fabric layer 2 or the second fabric layer 3.
To sum up, the utility model discloses its scope that can enlarge the precoat and choose for use can enough guarantee user's comfort level, can satisfy the relevant requirement of mechanical strength in the national standard GB4706.8 again.
