ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a container equipped with temperature warning device, more particularly, it relates to a double-layer container equipped with temperature warning device, wherein a temperature sensor device is used to detect temperature of hot food or hot soup loaded in the double-layer container for protecting people against being scalded when temperature is unbearable high.
2. Description of the Prior Art
As it is nothing rare that a user is scalded occasionally by carelessness when using a conventional single-layer container, a cup for example, loaded with hot liquid, therefore, a double-layer container for avoiding the user's hand touching the hot layer directly is substituted for the single-layer. However, the user may not be scalded again at his hand by a hot container wall, he may be scalded at his lip this time for being misled to mistake that the inside liquid is warm.
For reducing the possibility of the abovesaid unnecessary impairment and for ascertaining the right time to enjoy the food, a temperature display or warning device seems a feasible measure worthy of consideration.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide a double-layer container equipped with temperature sensor device, wherein a temperature sensor device is arranged in bottom end of a double-layer container for detecting temperature of food or soup loaded in the container to protect a user against being scalded.
Another object of this invention is to provide a double-layer container with temperature warning device, wherein different warning lights and corresponding songs are presented to indicate different temperature ranges.
In order to realize abovesaid objects, a double-layer container with temperature warning device of this invention comprises a double-layer container and a temperature sensor device. The temperature sensor device is disposed in a segregated space in the bottom end of the double-layer container and is composed of a microprocessor, a temperature sensor, and a warning device, wherein the warning device further comprises a plurality of LEDs in different colors and a speaker. The temperature sensor is attached onto an outside face at the bottom end of the double-layer container for detecting temperature of food or soup loaded in the container. A detected signal is transmitted from the temperature sensor to the microprocessor for judging to lighten a specified LED and drive the speaker to play a corresponding song for easy discrimination of the temperature range and thereby to protect a user against being scalded.
For more detailed information regarding this invention together with further advantages or features thereof, at least an example of preferred embodiment will be elucidated below with reference to the annexed drawings.
