Abstract

The invention provides a safe water drinking device with a movable electric heating water cup, comprising a water drinking device shell, a water nozzle, a movable electric heating water cup and a control circuit board; the water drinking device is provided with a table plate which is used for receiving the electric heating water cup and a socket specially used for the electric heating water cup; the electric heating water cup is provided with a power plug and an electric heating pipe or an electric heating wire; the control circuit board is provided with a load detection circuit and a relay CJ; the N wire and L wire of the power are electrically connected with the socket specially used for the electric heating water cup respectively by two pairs of normal-open contacts of the relay CJ; the load detection circuit is electrically connected with the socket specially used for the electric heating water cup respectively by two pairs of normal-close contacts of the relay CJ; when being started, the load resistance Rf is detected firstly; only when the load resistance Rf meets the requirement, the heating by electrifying or water pump starting can be carried out, thus improving the usage safety of the water drinking device.

Description

[0001] Technical field [0002] The invention relates to household appliances, in particular to a safety drinking fountain with a movable electric water cup. Background technique [0003] For drinking fountains with mobile electric hot water cups, there is a platen for placing electric hot water cups on the drinking fountains, and a water outlet faucet is arranged above the electric hot water cups. , The corresponding position on the drinking fountain is provided with a special socket for the electric hot water cup. When using, first put the electric water cup on the platen, and at the same time insert the plug on the electric water cup into the special socket, then turn on the tap to add an appropriate amount of water to the electric water cup, and then start the heating function to heat the water in the electric water cup. When the temperature of the water in the cup rises to the set temperature, the thermostat takes off and disconnects the heating power supply. [0004] ...
