Abstract

An improved structure of a clinical thermometer in which a dielectric (such as air or heat conductive, hard or soft foam with a low conductivity coefficient) is packed into the metal tip section of its measuring extremity such that the inductive component and the inductor wire disposed in the metal tip section are in a helical arrangement and entirely attached to the inner wall of the metal tip section, allowing inducted temperature to attain heat equilibrium as well as swift heat conduction, thereby enabling the clinical thermometer to immediately indicate the precise temperature. The clinical thermometer body is of one-piece molded construction and, furthermore, a pliable section having exceptional dustproof and waterproof properties is sleeved over the depressible flat element of its on-off switch. Slanted surfaces of mutual contact and conjoinment are disposed at an appropriate area of the measuring extremity and a rotation structure consisting of a flange mount and insertion holes at the contact and conjoinment surfaces enable the rotation of the measuring extremity and its rotating to an appropriate angle. As such, when the user employs the clinical thermometer to measure temperature, the movable structure of the measuring extremity enables ergonomic and comfortable grasping and manual retention.

Dependent claims

A structure of a clinical thermometer comprised of a clinical thermometer body, a measuring extremity conjoined to said body, a metal tip section sleeved onto said measuring extremity having an inductive component and inductor wire disposed inside, and a rear cover situated on the end of said body, wherein said inductive component and said inductor wire disposed in said metal tip section are entirely attached to the inner wall of said metal tip section such that inducted temperature attains heat equilibrium and heat conduction, enabling the clinical thermometer to immediately indicate the temperature, wherein said measuring extremity has a rotation structure consisting of an anterior portion and a base portion, each formed with a slanted surface of mutual contact and conjoinment, and wherein a flange mount having a lock rib is disposed on the slanted surface of said anterior portion and a lock sleeve having a projecting engagement edge is situated inside said base portion;

a stepped section is formed on said base portion that provides for the fitting on of a hollow metal sleeve such that said metal sleeve is contained within said lock sleeve;
and said metal sleeve has a slanted surface, with a large insertion hole merged to a small insertion hole formed in said slanted surface;
when said structure is assembled, said slanted surfaces of said anterior portion and said base portion are brought together and said flange mount is slipped into said large insertion hole which also enables its sliding into said small insertion hole such that said anterior portion and said base portion are in a conjoined arrangement capable of rotation;
the front end of said lock sleeve engagement edge is against said anterior portion slanted surface and, furthermore, extended into the smaller diameter root section of said flange mount to prevent the separation of said anterior portion from said base portion during rotation.
