DETAILED DESCRIPTION OF THE INVENTION

The detailed description and technical details of the present invention will be explained below with reference to accompanying drawings. However, the accompanying figures are only for reference and explanation, but not to limit the scope of the present invention.

Please refer to FIGS. 1 and 2, which show the heatable wear device according to the first embodiment of the present invention. The heatable wear device 10 mainly comprises a wear body 1, at least one heating module 2, and a circuit board 3.

The wear body 1 may be a glove, a sock, a vest, or a scarf; that is, an article worn on a person. The details are given below. The wear body 1 has a lining 11. In the current embodiment, the wear body 1 is a glove 12 which comprises five finger portions 121 and a wrist portion 122.

The lining 11 is formed on the inner surfaces of the respective finger portions 121.

In the current embodiment, the number of the heating modules 2 is five, but not limited to this. The five heating modules 2 are installed inside the wear body 1. In particular, each of the five heating modules 2 is installed inside the respective finger portions 121.

Each heating module 2 comprises an explosion-proof battery 21, a heating layer 22, and a 25 covering layer 23 with a high specific heat. The heating layer 22 is electrically connected to the

2018200246 12 Jan 2018 explosion-proof battery 21 and is disposed corresponding to the explosion-proof battery 21 and is attached to the lining 11. The covering layer 23 with a high specific heat is clamped between the explosion-proof battery 21 and the heating layer 22. The covering layer 23 with the high specific comprises a first surface 231 and a second surface 232 opposite to the first surface 231. The first 5 surface 231 is attached to the explosion-proof battery 21 and the second surface 232 is attached to the heating layer 22.

Besides, the explosion-proof battery 21 is a Solid State Battery (SSB) in which SSB, the flexible printed circuit, is used as the battery substrate and the packaging material, together with the SSB as the chemical system. In this way, the SSB has an extreme thickness ranging from 0.32 10 mm to 0.36 mm and can be bent with a radius of curvature ranging from 15 mm to 17 mm. When an SSB is bent, it remains the same electric properties as a flat (unbent) SSB and does not form wrinkles. Also, the SSB still has high safety even when it suffers the physical impact of bending, hammering, or cutting, undergoes the harsh temperature test, such as the oven test at 200 °C for 10 minutes, the hot plate test at 250 °C, or the high-temperature test of the flame gun at 700 15 °C-1000 °C, or other destructive testing of electrical properties. Consequently, the accident of fire, explosion, burning, and leakage can be avoided.

Moreover, the heating layer 22 is woven from meal wires made of, not limited to, iron, steel, or copper, or formed by the polyimide film heating pad or by the PTC (positive temperature coefficient) ceramic heating element. The covering layer 23 with the high specific heat is made of 20 ceramic yarn or nylon yam. The specific heat of the ceramic yam is about 840 J/(Kg^-K) and the specific heat of the nylon yam is about 1700 J/(Kg'K) such that when the ceramic yam and the nylon yam are heated to a high temperature, they will emit radiation heat.

The circuit board 3 is installed inside the wear body 1 and is electrically connected to the explosion-proof battery 21. The controller 31 is installed on the circuit board 3; the controller 31 25 controls electrical conduction and electrical insulation between the explosion-proof battery 21

2018200246 12 Jan 2018 and the heating layer 22 through the circuit board 3. In the current embodiment, the circuit board is installed inside the wrist portion 122.

The heatable wear device 10 of the present invention further comprises a USB connector 4 which is installed on the circuit board 3; the USB connector 4 has a USB female connector 41 5 and an extension cord 42. A terminal end of the extension cord 42 is connected to the USB female connector 41. The USB connector 4 is connected to an external charging connector 100 such that the external power supply can charge the explosion-proof battery 21.

The assembly of the heatable wear device 10 of the present invention is described below.

The heating module 2 is installed inside the wear body 1. The heating layer 22 is electrically 10 connected to the explosion-proof battery 21 and is disposed corresponding to the explosion-proof battery 21. The covering layer 23 with a high specific heat is clamped between the explosion-proof battery 21 and the heating layer 22. The covering layer 23 with the high specific comprises the first surface 23land the second surface 232 opposite to the first surface 231. The first surface 231 is attached to the explosion-proof battery 21 and the second surface 232 is 15 attached to the heating layer 22. The circuit board 3 is installed inside the wear body 1 and is electrically connected to the explosion-proof battery 21.

The operation of the heatable wear device 10 of the present invention used the following features. The explosion-proof battery 21 can be assembled closer to the heat layer 22; the covering layer 23 with a high specific heat of the explosion-proof battery 21 can be used as a heat 20 reservoir to absorb the heat radiated from the filament. Therefore, the heatable wear device 10 has the advantages of a compact assembly space, simpler assembly steps, reduced power consumption, energy saving, and concentrated heat sources.

In addition, as soon as the circuit is actuated, the explosion-proof battery 21 conducts electricity to the metal heating layer 22 such that the heating layer 22 heats the lining 11 directly 25 and heats the covering layer 23 with a high specific heat at the same time.

2018200246 12 Jan 2018

Then, when the circuit has been actuated for a while, the covering layer 23 with a high specific heat is heated to a high temperature and emits the radiation heat which heats the lining 11 again. As a result, the temperature of the lining 11 increases further.

Finally, when the temperature of the lining 11 increases again, the controller 31 controls the electrical insulation between the explosion-proof battery 21 and the heating layer 22 through the circuit board 3 to stop the heating of the heating layer 22. At this moment, the radiation heat stored in the covering layer 23 with a high specific heat is used to maintain the existing temperature to increase the operation time of the explosion-proof battery 21 under the same capacity and to reduce the volume of energy storage such that the heatable wear device 10 of the 10 present invention can achieve the effects of reduced power consumption and energy saving.
