Infrared touch device and profile

An infrared touch device comprising an infrared board for emitting and receiving infrared light, a light filtering portion, a panel, and an outer frame, the outer frame comprising a side frame portion, a front frame portion connected to a front end of the side frame portion, and a rear frame portion connected to a rear end of the side frame portion,

• wherein
• the side frame portion comprises a panel accommodating groove for accommodating an edge of the panel, a rear side face of the front frame portion forms a first side wall of the panel accommodating groove, an end face of a free end of the front frame portion is defined as a first inclined surface, and an obtuse angle is formed between the first inclined surface and the first side wall, and
• the first inclined surface forms a first reflecting surface, or a first reflecting layer is provided on the first inclined surface, an outer surface of the first reflecting layer forms a first reflecting surface, and at least part of the infrared light emitted by the infrared board passes through the light filtering portion and the panel in sequence, and is reflected by the first reflecting surface to propagate on a front side of the panel in a direction parallel to a front side face of the panel.
