STRUCTURE OF AN ELECTRONIC THERMOMETER

Abstract

A structure of an electronic thermometer which mainly includes a body portion, a temperature sensing head and a core. The core includes a temperature display screen, a printed circuit board provided with an electrical contact, and a conductor fixing rod arranged adjacent to the core. The conductor fixing rod is a flexible member on which is mounted a conductor against the electrical contact. The conductor fixing rod has an end fixed mounted on the core and another end of the conductor is free. A pushbutton switch is mounted on a rear end of the body portion. The pushbutton switch is arranged against a longitudinal end of the conductor fixing rod and can get in touch with and can be depressed to exert force on the conductor fixing rod in a direction along a length of the body portion or in an acute angle with respect to the length of the body portion.

Claims

1. A structure of an electronic thermometer comprising: a body portion in which is mounted a core, said core including a temperature display screen, a printed circuit board provided with an electrical contact, and a conductor fixing rod arranged adjacent to said core, said conductor fixing rod being a flexible member on which is mounted a conductor against said electrical contact;a temperature sensing head positioned at a front end of said body portion;wherein said conductor fixing rod has an end fixed mounted on said core, another end of said conductor is free, an on/off switch is mounted on a rear end of said body portion, said on/off switch is arranged against a longitudinal end of said conductor fixing rod and can get in touch with and can be depressed to exert force on said conductor fixing rod in a direction along a length of said body portion or in an acute angle with respect to said length of said body portion.

2. The structure of an electronic thermometer as claimed in claim 1, wherein adjacent ends of said pushbutton switch and said conductor fixing rod are provided with slanted surfaces which provide planar contact when getting in touch with each other.

3. The structure of an electronic thermometer as claimed in claim 1, wherein one of adjacent ends of said pushbutton switch and said conductor fixing rod has a slanted surface or curved surface, and said adjacent ends provide line contact when getting in touch with each other.

4. The structure of an electronic thermometer as claimed in claim 1, wherein one of the adjacent ends of said pushbutton switch and said conductor fixing rod has a slanted surface or curved surface, and said adjacent ends provide point contact when getting in touch with each other.

5. The structure of an electronic thermometer as claimed in claim 1, 2, 3 or 4, wherein said rear end of said body portion is provided with a cap which is detachably from an intermediate portion of said body portion, and said pushbutton switch is mounted on said cap along a longitudinal axis of said cap or along an axis biasing from said longitudinal axis.

6. The structure of an electronic thermometer as claimed in claim 5, wherein said pushbutton switch is a flexible key.

7. The structure of an electronic thermometer as claimed in claim 1, 2, 3 or 4, wherein said rear end of said body portion is integrally formed with an intermediate portion of said body portion.

8. The structure of an electronic thermometer as claimed in claim 7, wherein said pushbutton switch is a rigid member having a pin extending through a hole of a partition in said body portion to be located against said conductor fixing rod and to be able to get in touch with said conductor fixing rod, and a reset member is provided between said pin and said partition.

9. The structure of an electronic thermometer as claimed in claim 8, wherein a spring is fitted between said pushbutton and the partition for returning said pushbutton to an original position when said pushbutton is released.

10. The structure of an electronic thermometer as claimed in claim 1, wherein said temperature sensing head and said body portion are integrally formed and said temperature sensing head is flexible in property.
