Spray device and fan

A spray device, comprising:

• an inner shell (100), wherein the inner shell (100) is provided with a hollow water storage chamber (110), a first spray through hole (111) communicating with the water storage chamber (110) is provided on one side of the inner shell (100), a water injection hole (112) is provided on the other side of the inner shell (100), the water injection hole (112) connects the water storage chamber (110) with a water injection guide member (800), and the water injection guide member (800) is configured to inject water into the water storage chamber (110);
• an atomization assembly, wherein the atomization assembly is embedded in the first spray through hole (111) and is configured to atomize liquid in the water storage chamber (110) and spray the liquid out of the water storage chamber (110);
• a recirculation assembly (300), comprising a recirculation port (301) provided at the bottom of the inner shell (100) and a water return channel (302) for connecting the recirculation port (301) with the water storage chamber (110);
• an outer shell (400), wherein the outer shell (400) is sleeved on an outer side of the inner shell (100), the outer shell (400) is provided with a second spray through hole (410) communicating with two opposite sides of the outer shell and facing the atomization assembly, a water collection tank (411) is provided at the bottom of the outer shell (400), and the recirculation port (301) is located in the water collection tank (411);
• a sensing assembly, wherein the sensing assembly is provided in the water storage chamber (110) and is closer to a top wall of the water storage cavity than the atomizing assembly;
• and
• a control assembly, wherein the control assembly is connected to a signal of the sensing assembly and is configured to control the water injection guide member (800) to inject the water into the water storage chamber (110) and control the water injection guide member (800) to stop injecting the water into the water storage chamber (110) based on the signal of the sensing assembly.
