Temperature control heat insulating cup

Abstract

The invention discloses a temperature control heat insulating cup, which comprises a cup body, a cup cover, an electric heating plate, a temperature sensor, a micro-controller, an indicator light and a bottom shell, wherein the electric heating plate is fixed on the cup body bottom surface; the temperature sensor is fixed on a lower end of an inner wall of the cup body; the electric heating plate is parallelly connected to the temperature sensor and then is connected to the micro-controller to form a closed circuit; the micro-controller is a PLC controller; the bottom shell is fixed on a lower portion of the cup body; a USB connecting port is set on a side wall of the bottom shell; and the power source can be connected through a power source lead with one end as a USB head. When the water temperature inside the cup is lower than the preset temperature; the electric heating plate is controlled by the micro-controller to heat; when the water temperature reaches at a boiling point, the electric heating plate is controlled by the micro-controller to stop heating; the heat insulation to hot water is realized by the automatic control, thus satisfying the need of drinking at any time; the USB connecting port is connected to a mobile power source conveniently, thus the USB connecting port is suitable for outdoor use; the use range is expanded; and the temperature control heat insulating cup has simple structure, thus the cup is portable; and the temperature control heat insulating cup is easily popularized and used.

Description

Technical field [0001] The invention relates to a thermal insulation cup, in particular to a temperature control thermal insulation cup, belonging to the field of daily necessities. Background technique [0002] Thermal insulation of hot water is what people need in daily life. Although the boiling water bottle has a long thermal insulation time, it is not convenient to carry. At present, there is a portable thermal insulation cup on the market. It has a double-layer vacuum structure. The cup has a press-type lid with a sealing ring and an ordinary lid on the outside. This double-layer double-lid structure extends the heat preservation time of the water in the cup. However, there are still shortcomings, not only the holding time is limited, when the cup is filled with only part of the water, the holding time is greatly shortened compared to that of the full water. [0003] China invented "a thermal insulation cup for mountain climbing" (CN204467319U) discloses a thermal insulation...

AI Technical Summary

Problems solved by technology

The thermos cup for mountain climbing realizes automatic heating to achieve the purpose of heat preservation, but the solar battery is greatly affected by the weather, and the stable heat preservation effect cannot be achieved in rainy weather and winter. In addition, due to the limited surface area of ​​the cup, the solar panel on the surface of the cup cannot be too large. , so the battery power is small, and it takes a long time to heat up once
