ELECTRONIC THERMOMETER
First Claim
1. An electronic thermometer, comprising:
- an external casing unit including a pivot shaft, a receiving space and an extending portion, wherein the pivot shaft is disposed on the extending portion and outside the receiving space, the external casing unit includes a top cover casing and a bottom cover casing, the receiving space is formed between the top cover casing and the bottom cover casing, and the bottom cover casing has a through hole communicated with the receiving space;
a circuit substrate disposed inside the receiving space;
an electronic switch electrically connected to the circuit substrate, wherein the electronic switch includes a trigger portion disposed inside the through hole and corresponding to the pivot shaft;
a rotating arm unit including a rotation base, a concave groove and a pivot portion, wherein the rotation base is pivotally disposed on the pivot shaft through the pivot portion, and the rotation base is reciprocatedly moved between a first position and a second position relative to the pivot shaft;
a probe unit disposed on the rotating arm unit and electrically connected to the circuit substrate; and
a waterproof unit including a first waterproof element and a second waterproof element for covering the trigger portion of the electronic switch;
wherein when the rotation base is moved from the second position to the first position, the rotation base is separated from the trigger portion of the electronic switch;
wherein when the rotation base is moved from the first position to the second position, the rotation base is abutted against the trigger portion of the electronic switch to turn on the electronic switch;
wherein the first waterproof element is disposed between the top cover casing and the bottom cover casing and around the receiving space for preventing water vapor from entering the receiving space through the external casing unit;
wherein the second waterproof element is disposed inside the through hole of the bottom cover casing for preventing water vapor from entering the receiving space through the through hole.

Abstract
An electronic thermometer includes an external casing unit, a circuit substrate, an electronic switch, a rotating arm unit, a probe unit and a waterproof unit. The external casing unit includes a top cover casing and a bottom cover casing, a receiving space is formed between the top and the bottom cover casings, and the bottom cover casing has a through hole communicated with the receiving space. The waterproof unit includes a first waterproof element and a second waterproof element. The first waterproof element is disposed between the top cover casing and the bottom cover casing and around the receiving space for preventing water vapor from entering the receiving space through the external casing unit, and the second waterproof element is disposed inside the through hole of the bottom cover casing for preventing water vapor from entering the receiving space through the through hole.
