Flow dividing structure used for recovering cold water

The invention discloses a flow dividing structure used for recovering cold water. The flow dividing structure comprises an outer sleeve; a flow dividing cavity, a backflow cavity and a hot water cavity are arranged in the outer sleeve; the backflow cavity is communicated with the flow dividing cavity through a first port; the hot water cavity is communicated with the flow dividing cavity through a second port; a piston barrel is arranged in the flow dividing cavity; a certain gap exists between the outer wall of the piston barrel and the inner wall of the outer sleeve; a first through hole, a second through hole and a third through hole are formed in the barrel wall of the piston barrel; a temperature sensing actuator and a first elastic part are arranged in the piston barrel; the temperature sensing actuator is provided with a disk seal; the inner wall of the outer sleeve is provided with an elastic element; at least 1ML of water can be contained in the cavity located at the left side of the piston barrel in the outer sleeve. According to the flow dividing structure disclosed by the invention, accurate cold water and hot water flow dividing can be realized through sliding fit between the piston barrel and the outer sleeve, and meanwhile, the outlet water temperature of hot water can also be regulated as needed; the flow dividing structure has the advantages that judgment is accurate, the backflow efficiency is high, the operation is stable, and the service life is long.
