the cleaning module is configured in the body and includes a cleaning pipeline and a valve body, wherein the cleaning pipeline is connected to a cleaning liquid source and the inlet end, the valve body is connected to the cleaning pipeline, the control unit is connected to the valve body. ## Claims ### Claim 1 A beverage cooling device, comprising: a body, a first cooling tank, configured in the body and filled with a first coolant, wherein the first cooling tank is configured with a first temperature sensor; a second cooling tank, configured in the body and filled with a second coolant, wherein a temperature of the second coolant is lower than that of the first coolant, the second cooling tank is configured with a second temperature sensor; a cooling pipeline, including: a first pipeline, configured in the first cooling tank and connected to an inlet end; and a second pipeline, configured in the second cooling tank and connected to the first pipeline and an outlet end; a cleaning module, configured in the body and including: a cleaning pipeline, connected to a cleaning liquid source and the inlet end; and a valve body, connected to the cleaning pipeline; and a control unit, connected or electrically connected to the valve body; wherein each the first cooling tank and the second cooling tank is respectively configured with an intake valve and a drain valve, and the first temperature sensor, the second temperature sensor, each intake valve and each drain valve are electrically connected to the control unit; wherein when the first temperature sensor detects that the temperature of the first coolant is higher than a first temperature threshold, the control unit opens the intake valve and the drain valve of the first cooling tank, so that the temperature of the first coolant is lower than or equal to the first temperature threshold; wherein when the second temperature sensor detects that the temperature of the second coolant is higher than a second temperature threshold, the control unit opens the intake valve and the drain valve of the second cooling tank, so that the temperature of the second coolant is lower than or equal to the second temperature threshold. ### Claim 2 (depends on 1) The beverage cooling device according to claim 1, wherein the second pipeline is coiled, the inlet end is suitable to inject a beverage, and a temperature of the beverage is higher than that of the second coolant. ### Claim 3 (depends on 2) The beverage cooling device according to claim 2, wherein the first pipeline is coiled, the number of turns of the second pipeline is greater than the number of turns of the first pipeline, and the temperature of the beverage is higher than that of the first coolant. ### Claim 4 (depends on 1) The beverage cooling device according to claim 1, further comprising a second coolant source tank, the second coolant source is configured within the second coolant source tank, the second coolant source tank is configured with a heat exchanger and a pump, the exchanger and the pump are electrically connected to the control unit, and the intake valve and the drain valve of the second cooling tank are connected to the second coolant source tank. ### Claim 5 (depends on 1) The beverage cooling device according to claim 1, further comprising a beverage storage tank, the beverage storage tank is configured within the second cooling tank, and the beverage storage tank is connected between the first pipeline and the second pipeline or between the second pipeline and the outlet end. ### Claim 6 (depends on 1) The beverage cooling device according to claim 1, further comprising an ice making tank, the ice making tank is configured with an auxiliary chilling unit thereon, and the first pipeline or the second pipeline is connected to the ice making tank. ### Claim 7 (depends on 1) The beverage cooling device according to claim 1, further comprising a compressor and a chilling unit, the compressor is electrically connected to the control unit, the first cooling tank and the second cooling tank are communicated to each other, and the chilling unit is connected between the compressor and the second cooling tank. ### Claim 8 (depends on 7) The beverage cooling device according to claim 7, further comprising a heat dissipation unit, the heat dissipation unit is connected to the compressor and electrically connected to the control unit. ### Claim 9 (depends on 1) The beverage cooling device according to claim 1, wherein tank walls of the first cooling tank and the second cooling tank are made of heat insulating materials.
