Cyclic preheating coffee pot and working method thereof

A cyclic preheating coffee pot, comprising a main body, a brewing cavity, a water supply apparatus, a heating apparatus, a water inlet pipe and a water outlet pipe mounted on the main body respectively, the cyclic preheating coffee pot further comprising a control apparatus, a driving apparatus and a flow dividing structure mounted on the main body, wherein the water supply apparatus is communicated with the heating apparatus via the water inlet pipe, the water supply apparatus is configured to supply water to the heating apparatus via the water inlet pipe, a first end of the water outlet pipe is communicated with the heating apparatus and a second end of the water outlet pipe is communicated with the flow dividing structure;

• the flow dividing structure comprises a first branch and a second branch, the water outlet pipe is communicated with the water supply apparatus via the first branch, such that the water supply apparatus, the water inlet pipe, the heating apparatus, the water outlet pipe and the first branch are communicated in sequence and a cyclic pipeline can be formed;
• the cyclic pipeline is provided with a one-way valve apparatus to define a direction of a water flow, or the cyclic pipeline is provided with a water pump to define the direction of the water flow;
• the heating apparatus is configured for preheating or heating water flowing into the heating apparatus, the second branch is provided with a water outlet switch, and the water outlet switch is used for opening or closing the second branch, such that when the water outlet switch is turned on, the water outlet pipe is communicated with the brewing cavity via the second branch, and when the water outlet switch is turned off, the water outlet pipe is not communicated with the brewing cavity, and the control apparatus is electrically connected to the driving apparatus, and the control apparatus is configured to control the driving apparatus, such that the driving apparatus drives the water outlet switch to be turned on, and therefore, water flows through the second branch from the water outlet pipe and enters the brewing cavity.
