[0012] Specifically, a water inlet seat is further extended backward from the lower part of the heat exchange shell, and the water inlet seat is connected to the instant heater; the water inlet seat is convenient for connection with an external water source (such as a bucket or a water tank).

[0013] Specifically, the heat exchange tube is in a coiled shape; the coiled heat exchange tube has a longer path, so that the hot water can be fully heat exchanged in the heat exchange tube, which is conducive to cooling the hot water into warm water.
