(20) Preferably, a side of the shell (1) of the temperature measurement probe is, as in FIG. 5, provided with an injector pin (11) for switching between ear temperature measurement and non-contact temperature measurement. The injector pin (11) is connected with the temperature measurement control unit circuit in the main body shell and its upper end interacts with inner wall of the non-contact temperature measurement component (3): When the non-contact temperature measurement component (3) fits over the shell (1) of the temperature measurement probe, the injector pin (11) will be pressed down by the non-contact temperature measurement component (3) and the temperature measurement control unit will detect it and switch to non-contact temperature measurement; after the non-contact temperature measurement component (3) is removed from the shell (1) of the temperature measurement probe, the injector pin (11) will bounce up and the temperature measurement control unit will switch to ear temperature measurement.

(23) FIG. 12 to FIG. 14 are exploded view, operating principle diagram and circuit diagram of the product involved in the embodiment of the present invention. The technical solution of the present invention is not limited to the product outline shape in FIG. 12. The temperature measurement control unit and the display unit in the technical solution are currently universal.
