Writing pen with a liquid crystal screen displaying the tested alcohol concentration value
First Claim
1. A writing pen with a liquid crystal screen displaying the tested alcohol concentration value, including:
- a lower barrel;
an upper barrel, which is engaged with one end of the lower barrel; and
a sensor device, which is engaged with the other end of the upper barrel and has a housing and a circuit board;
a gas convection slot and a panel opening are located on the housing, whereas the circuit board is installed inside the housing;
a sensor and a liquid crystal screen that fits in the panel opening are installed on and electrically connected to the circuit board;
when the sensor device is in the standby mode, the user breathes against the gas convection slot, and through the sensor, the level of the alcohol concentration in the user'"'"'s exhaled breath can be received to a processing unit to be converted into a precise value so that the sensor device can display the precise value on the liquid crystal screen;
hence, the purpose of testing the precise value of the alcohol concentration in the user'"'"'s breath has been achieved.

Abstract
The invention relates to a writing pen with a liquid crystal screen displaying the tested alcohol concentration value, and its architecture includes a lower barrel, an upper barrel, and a sensor device. The sensor device has a circuit board, wherein a sensor, a liquid crystal screen, and a processing unit are installed on and electrically connected to the circuit board. The circuit board receives the alcohol content in the user'"'"'s exhaled breath and converts it so that a precise value can be displayed on the liquid crystal screen. Hence, a writing pen that can be readily carried and has a liquid crystal screen displaying the tested alcohol concentration value is completed.
