Abstract

The utility model discloses a heating cushion which comprises a multifilament carbon fiber heating element and a pair of thin-sheet plates, wherein filaments in the carbon fiber heating element are mutually parallel and extends in substance under the condition that the filaments are not wrung, and the heating element is fixed a suitable position between the thin-sheet plates; the thin-sheet plates are mutually bonded together. The heating cushion in the utility model can be made into a low-voltage heating product according to different application.

Description

Heating pad and the product of this heating pad is installed

Technical field

The utility model relates to a kind of heating pad, more particularly, relates to a kind of flexible heating pad with soft multi-filament carbon fiber heater element or smooth carbon film heating element, and the utility model also relates to a kind of product that this heating pad is installed.

Background technology

Electric blanket, the heating pad that is used for the elderly, the embedded electric heating device that is used for automotive seat and similar device have all used hard metallic conductor.Such as, electric blanket has copper conductor, and these copper conductors quilts are twisted together mutually, and are covered by in plastics or the gas-insulated overcoat.When couching on this electric blanket, people can feel the discomfort that is produced by conductor, though conductor be a thin plate and may be that a liner also is so because conductor has certain thickness and hard.

Electric heating pad for less also can run into identical situation, such as the heating pad that can carry out physical treatment to arthritis patient or the elderly.

Creator in the utility model relies on it to be engaged in the experience and the practice of associated row for many years for this reason, and through concentrating on studies and developing, creates a kind of heating pad that can obviously improve the use sense of discomfort that metallic conductor produced finally.

Summary of the invention

The purpose of this utility model is to provide a kind of heating pad, and this heating pad has soft flexible heater element, effectively improves existing heating pad because of adopting the sense of discomfort that metallic conductor produced.

Heating pad in the utility model comprises:

A multi-filament carbon fiber heater element, the filament in this carbon fiber heating element are extension in parallel to each other basically under the condition that twisting does not take place, and

The fine sheet that a pair of mutual bonding is got up, described heater element is fixed between them fine sheet by this.

Described heater element is circuitous crooked form and distributes.

Each end of described heater element is attached on the lead by a crimping plate.

The laying that on each side of this heating pad, all has a softness.

Be coated with a skin on the laying of described softness.

Described heater element is substituted by a smooth carbon film.

Heating pad in the utility model utilizes flexible heater element, and effectively improve existing heating pad because of adopting the sense of discomfort that metallic conductor produced, and can be made into the multiple heating product of low-voltage according to different application, as the heating pad in the utility model is fixed on clothes inside, is located in blanket centre or other fabric by the method for making, can both form various heating products.

Embodiment

The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, the heating pad 10 in the utility model comprises a pair of plastic tab laminated together 11, and a multi-filament carbon fiber heater element 12, and this multi-filament carbon fiber heater element 12 is fixed between two plastic tabs 11.Heater element 12 is circuitous curve form, and is fixed with a pair of through one in the plain conductor 14 of insulation on its respective end.Each root lead 14 all is connected on the respective end of heater element 12 by a metal crimp fishplate bar 13.It is compound that heater element 12 in the utility model can carry out winding displacement by a whole Shu Yuansi, thereby can effectively control the surface area of heating pad, and make heating power more even.

As shown in Figure 2, the manufacture method of heating pad is in the utility model:

At first heater element 12 is positioned on the anchor clamps, these anchor clamps comprise a pair of arm 15, and each arm 15 all has the crooked lug plate 16 of row's linear array.Wherein continuous heater element 12 extends between arm 15 back and forth around lug plate 16.

Then be to make the side of each plastic tab 11, bondd mutually, keep thus being in spaced relationship between the corresponding parallel portion near parallel lines part on the heater element 12.The crooked end of described heater element 12 disassembles from the lug plate 16 of anchor clamps arm 15 subsequently.Before or after this step, utilize metal crimp fishplate bar or crimping post 13 that lead 14 is crimped on the respective end of heater element 12.

The remainder of last plastic tab 11 is pressed against together subsequently mutually, surrounds the end of crooked end, crimping metalwork 13 and two leads of heater element 12 thus.Because lead 14 is through insulation processing, so final heating pad is also insulated fully.

Filament in the carbon fiber heating element 12 that the utility model adopted is similar to hair, and is perhaps more meticulous, but the gross thickness of heater element can be 1 millimeter.When plastic tab 11 is pressed against a time-out mutually, heater element 12 can be compressed and is crushed slightly along with fibre bundle.Should be appreciated that, the extension that is parallel to each other of described fiber, and can twisting not take place as the copper conductor in the stranded conductor, so just can make and scatter, a not too outstanding element and a more comfortable heating pad is provided thus when plastic tab is compressed against a time-out fiber strand rope.

In the ambroin thin slice 11 one or all can be on a side gluing in advance.Also can execute caloric value and make described two plastic tabs fuse together, simultaneously heater element 12 between them, thereby guarantee the safety and the heat dissipation characteristics of whole heating pad, avoid the short circuit that causes because of heating wire is overlapping.

The liner of one deck softness can be set on each side of described heating pad, and the another one skin can be set on described liner.

In addition, need should be appreciated that those conspicuous for the skilled artisan in the art changes and replacement can not be considered to exceed protection range of the present utility model.Also have, do not breaking away under the condition of the present utility model, can obtain other purposes of described heating pad.For example, can produce the clothing that wherein is formed with described heating pad, as shown in Figure 3, heating pad in the utility model is fixed on clothes inside by the mode of making, make clothes when wearing, have heating function, in addition, heating pad in the utility model also can be made in inside such as blanket, cushions, make things convenient for our usefulness of warming oneself, and the product that the heating pad in the utility model is installed has good flexibility in use, can effectively improve the discomfort of present heating pad because of using metallic conductor to produce.Also have, heating pad can use a kind of smooth silk ribbon shape carbon film to replace the non-twisting carbon fiber heating of multifilament element in the utility model, also has, and can adopt any other conventional configurations, replaces heater element such as spiral form and is arranged to circuitous curve form.
