I. Brief description
In today's society where cars are popular, traveling by car has become part of people's daily work and life. When driving out in cold weather, most people still want to have hot water and beverages, and a car heated mug can provide such convenience.

II. Characteristics
Since the road conditions of automobile driving are unpredictable, there will be a certain risk factor for in-vehicle heating until the water boils. So this car heating cup is heated for bottled mineral water and canned drinks (not including carbonated drinks). This is to ensure that people can drink hot beverages under the premise of driving safety.

III. Design objectives
Easy access to hot canned/bottled water and beverages in the car.

IV. Design Principles
When the canned beverage is put into the heated cup, the sensor automatically recognizes the water temperature and performs the heating/warming process, keeping the water temperature between 30℃ and 55℃. When heating is complete, a buzzer will remind the user that heating is complete, and the LED light will also indicate the heat preservation. It also has the ability to recognize the short circuit or broken circuit of the sensor, which improves the safety factor of the product.
