  • DETAILED DESCRIPTION
  • [0010]
    FIG. 1 shows a heated shoe 100, according to an exemplary embodiment of the disclosure. The heated shoe 100 can automatically generate electric energy through electromagnetic induction and converts the electric energy into heat.
  • [0011]
    Also referring to FIG. 2, the heated shoe 100 includes a main body 20, an insole 30, a protection layer 40, a heat conducting layer 50, a sole 60, and a heat generating module 70. The insole 30, the protection layer 40 and the heat conducting layer 50 are located between the main body 20 and the sole 60 in turn.
  • [0012]
    The insole 30 is located within the main body 20 and can be made from heat insulation material and soft magnetic material, having warm and healthy benefits. The protection layer 40 is located at one side of and adjacent to the insole 30 and can be made from insulation material. The protection layer 40 is capable of preventing the electric energy from the heat generating module 70 from transmission to users.
  • [0013]
    The sole 60 is located at one side of the main body 20 and can be made of elastic material, therefore, the sole 60 is capable of elastically deforming and automatically restoring its initial shape after elastic deformation. The sole 60 defines a receiving space 62 substantially at the heel of the heated shoe 100, the receiving space 62 is capable of receiving the heat generating module 70.
  • [0014]
    The heat generating module 70 is capable of generating induced current by electromagnetic induction and includes a power generating unit 71, a rectifying circuit 73, a first switch 74, a power storage unit 75, a heat generating unit 76, and a second switch 77. The power generating unit 71 includes a magnet 712 and a coil 714.
  • [0015]
    In this exemplary embodiment, the magnet 712 can be a substantially cylindrical or rectangular shaped permanent magnet, and is located at the upper wall of the receiving space 62. The coil 714 can be made of copper and is a substantially cylindrical or rectangular shaped inductive coil corresponding to the magnet 712. The coil 714 is located at the bottom wall of the receiving space 62 and is aligned with the magnet 712. Thus, when the sole 60 is elastically deformed or is restored its elastic deformation, the sole 60 drives the magnet 712 to reciprocate in the coil 714. Thus, the coil 714 cuts magnetic field lines of the magnet 712 to generate induced current therein according to the principle of electromagnetic induction.
  • [0016]
    The rectifying circuit 73 is in electronic communication with the coil 714 of the power generating unit 71, and substantially includes transformers, rectifiers, filters, rectifier diodes, and other electronic components. The rectifying circuit 73 is capable of receiving and converting the induced current from the coil 714 into corresponding direct current (DC).
  • [0017]
    The first switch 74 can be a single pole double throw (SPDT) switch, and includes a common end 742, a first fixed contact 744, and a second fixed contact 745. The common end 742 is in electronic communication with the rectifying circuit 73, and the first fixed contact 744 and the second fixed contact 745 are electrically connected to the power storage unit 75 and the heat generating unit 76, respectively.
  • [0018]
    The power storage unit 75 can be a storage battery and is capable of storing electric energy and providing electric energy for the heat generating unit 76. In this exemplary embodiment, when the common end 742 of the first switch 74 is switched on to electrically connect the first fixed contact 744, the power storage unit 75 receives and stores the electric energy from the rectifying circuit 73.
  • [0019]
    The heat generating unit 76 can be a heater strip made from aludirome, nickel aluminium alloy or other alloy materials. The heat generating unit 76 is located in the heat conducting layer 50, arranged as grid-like arrangement. Thus, when the common end 742 of the first switch 74 is switched on to electrically connect the second fixed contact 745, the heat generating unit 76 electrically connects the rectifying circuit 73 and rectifies the electric energy from the rectifying circuit 73 into heat provided for the heated shoe 100.
  • [0020]
    The second switch 77 can be a single pole single throw (SPST) switch and is electrically connected between the power storage unit 75 and the heat generating unit 76. In this exemplary embodiment, when the second switch 77 is turned on, the power storage unit 75 selectively and electrically connects to the heat generating unit 76 to provide electric energy for the heat generating unit 76 which can generate heat at any time.
  • [0021]
    Further referring to FIGS. 1 and 2, in use, the users press and force the sole 60 in the course of walking or exercise, making the sole 60 elastically deform and restore elastic deformation, so the magnet 712 moves back and forth alternately in the coil 714. Thus, the closed coil 714 continues to cut the magnetic field lines of the magnet 712 to generate induced current within the coil 714. The rectifying circuit 73 processes, and rectifies the induced current from the coil 714 into corresponding stable DC. When the common end 742 of the first switch 74 is switched on to electrically connect the second fixed contact 745, the heat generating unit 76 electrically connects the rectifying circuit 73 and converts the electric energy from the rectifying circuit 73 into heat, provided for the heated shoe 100. When the common end 742 of the first switch 74 is switched on to electrically connect the first fixed contact 744, the power storage unit 75 electrically connects the rectifying circuit 73, receiving and storing the electric energy from the rectifying circuit 73.
  • [0022]
    In this exemplary embodiment, when the users are not moving, the second switch 77 can be selectively switched on, the heat generating unit 76 then is electrically connected to the power storage unit 75, and converts the electric energy stored in the power storage unit 75 into unrestricted heat for the heated shoe 100.
  • [0023]
    The heat generating module 70 further includes an interface 78, which includes hardware and associated circuitry and is implemented to link one device with another. In this exemplary embodiment, the interface 78 is electrically connected to the power storage unit 75, so the power storage unit 75 can electrically connect to an electronic device (not shown), such as a mobile phone, to power the electronic device.
  • [0024]
    Moreover, the sole 60 further includes at least one spring 64 received within the receiving space 62. The opposite ends of each spring 64 are fixed at the upper wall and the bottom wall of the receiving space 62 respectively. Thus, the springs 64 and the sole 60 elastically deform and restore elastic deformation to force the magnet 712 to reciprocate in the coil 714, so the closed coil 714 cuts the magnetic field lines of the magnet 712 to generate induced current therein.
  • [0025]
    Additionally, the sole 60 further includes an iron plate 66. The iron plate 66 is located on and adjacent to the magnet 712, and is capable of maintaining and enhancing the magnetism of the magnet 712.
  • [0026]
    In summary, in the heated shoe 100 of the exemplary embodiment of this disclosure, if the users presses the sole 60, the power generating unit 71 generates induced current based on electromagnetic induction. The induced current is rectified and processed, and then is transmitted to the heat generating unit 76, and the heat generating unit 76 converts electric energy into heat provided for the heated shoe 100, which can meet the requirements of the users. In addition, the electric energy from the power generating unit 71 can be stored within the power storage unit 75, as to provide the electric energy for the heat generating unit 76. Thus, the heated shoe 100 can generate unrestricted heat.
