Abstract: A temperature detecting structure for electronic thermometer includes a thermometer shell having a tubular front extension end, two conductors arranged in parallel in the shell, a solid temperature tip fixedly fastened to the thermometer shell to close its tubular front extension end, and a chip connected to the conductors and fixedly mounted inside the solid temperature tip to directly receive heat from the solid temperature tip.

Abstract: An improved ear thermometer head includes a waveguide, a thermometer and a waveguide protective cover. The outer detecting end face of the waveguide protective cover is integrally formed and seamlessly connected to a transparent piece so that the outer detecting end face of the waveguide protective cover is in an enclosed and seamless state to shield an exposed clearance between the interior of the waveguide protective cover and the waveguide, thereby preventing entry of pollutants, such as water and dust. The outer detecting end face is substantially transparent, and is hardened and polished to effectively permit accurate light penetration. If there is water on the outer detecting end face or if it is dirty, it can be wiped clean, sterilized or washed. As such, the cleanliness and hygiene of the outer detecting end face of the waveguide protective cover is ensured, and besides, use of an additional cap to cover the waveguide protective cover is eliminated.
