Electric-heating apparatus and touch device therein

An electric-heating apparatus, comprising:

• a body;
• a heating device disposed in the body;
• and
• a touch device, disposed in the body, is configured to control the operating status of the heating device, wherein the touch device comprises:
• a substrate having a top surface and comprising a first connecting member disposed on the top surface of the substrate;
• a plurality of light-emitting elements disposed on the top surface of the substrate;
• a light-shielding member disposed on the top surface of the substrate, wherein the light-shielding member has a plurality of first openings, and the light-emitting elements are correspondingly located in the first openings, wherein the light-shielding member is located between the first connecting member and the light-emitting element, and the first connecting member and the light-emitting element are separated by the light-shielding member, thereby the first connecting member is completely blocked from the light-emitting element by the light-shielding member, wherein the light-shielding member further has a hole, the hole and the first opening penetrate on the same plane, and a central axis of the hole is parallel to a central axis of the first opening and perpendicular to said same plane, and the first connecting member is located in the hole;
• a sensing board, disposed on the light-shielding member, and electrically connected to the substrate via the first connecting member, wherein the sensing board has a plurality of second openings, and the first openings and the second openings correspondingly overlap;
• and
• a light-passing board, disposed on the sensing board, is configured to cover the first openings and the second openings.
