Description

Temperature spoon

A temperature-sensitive spoon, especially a spoon that is suitable for use in tableware to detect food temperature and project light.

With the progress of society, the quality of life is increasingly demanding. In terms of diet, the temperature of food greatly affects the taste and appetite of eating. When the food is at high temperature, it can be visually observed whether there is thick vapor on the surface of the food, but gradually with the temperature. If it is lowered, it will cause a great error when it is observed by the eyes. If the temperature is still high, it will cause accidents such as lip burns caused by eating by the consumers. Especially for the elderly, young people or people with disabilities, these problems are more likely to occur. When it is too cold to eat, in addition to poor taste, it is also easy to hurt the stomach.

However, traditional tableware (such as: cutlery, chopsticks or spoons, etc.) only provides the function of picking and dropping food, does not have temperature sensing and reminding function, and the safety of use is considered.

The main purpose of this creation is to provide a method for detecting the temperature of the food and projecting the light at a preset temperature value, thereby quickly and accurately knowing the temperature of the food, having a reminding function, and improving practicality and safety.

The secondary purpose of this creation is to vary the temperature of the food being detected, It will project different color light sources to add practicality.

In order to achieve the above object, the temperature sensing spoon of the present invention comprises a body and a control module disposed in the body, the body has a handle, a cover and a spoon, the cover is connected to the upper end of the handle, and the spoon is connected to the lower end of the handle. The control module comprises a light-emitting module and a temperature-sensing component connected to each other. The light-emitting module is composed of a circuit substrate, a light-emitting diode and a battery, so that the light-emitting module is located at the handle of the body, and the temperature sensing component extends to the body. Below the handle and near the spoon, the temperature sensing element detects the temperature of the food to transmit the temperature sensing signal to the light emitting module, and the light emitting diode of the light emitting module emits a light source to project light from the handle of the body . In addition, the user can identify the color of the light source in the handle of the spoon, and can quickly and accurately know the temperature of the food, and has the instantness and the reminding effect, and is more practical and safe.
