When the fluid flows through the water outlet 10, the flow switch assembly 21 feeds back the flow condition to the control box. The switch base 212 of the flow switch assembly 21 moves toward the direction (Q direction in FIG. 4 ) close to the magnetic switch 211 with the thrust of the fluid. The box sends a heating start signal, and the control box drives the heating core 12 to work normally. The temperature control probe 131 can feed back the water temperature to the control box. When the temperature control probe 131 at the water inlet 13 detects that the fluid temperature reaches or exceeds the set threshold (for example, 45 degrees Celsius), the temperature control probe 131 sends a signal to the control box to stop heating. signal, the control box drives the heating core 12 not to work. The fluid in the pipeline 1 finally flows into the heating pool through the water outlet 10 .

The present application also provides a heated water pool, including the heater described in any one of the above.
