Beverage machine

A beverage machine, comprising:

• a main body having a main body water inlet;
• a water tank detachably connected to the main body, wherein the water tank has a water inlet and a water outlet, and the water outlet is in communication with the main body water inlet;
• wherein the water inlet is configured to be selectively set to any one of a closed state, a first state, or a second state;
• when the water inlet is in the closed state, a water source of the main body comes from the water tank;
• when the water inlet is in the first state, the water inlet is in communication with a first water supply pipeline, and the water source of the main body comes from a water distribution network connected to the first water supply pipeline;
• when the water inlet is in the second state, the water inlet is in communication with a second water supply pipeline, and the water source of the main body comes from a barreled water source connected to the second water supply pipeline;
• wherein an on-off valve is provided on the first water supply pipeline, and the on-off valve is configured to control connection or disconnection of a water passage from the water distribution network to the water inlet;
• a first water pump is provided on the second water supply pipeline, and the first water pump is configured to drive water flow from the barreled water source to the water inlet;
• a first liquid level sensor configured to detect a liquid level height in the water tank;
• and
• a controller, wherein the controller is communicatively connected to the first liquid level sensor;
• as the liquid level height is lower than a first liquid level height:
• when the water inlet is in the first state, the controller controls the on-off valve to open to replenish water to the water tank through the first water supply pipeline;
• when the water inlet is in the second state, the controller controls the first water pump to open to replenish water to the water tank through the second water supply pipeline;
• when the water inlet is in the closed state, the controller generates a signal for reminding a user to replenish water to the water tank.
