One end of the heating pipe 12 is fixedly connected to the connecting pipe 11. The connecting pipe 11 is connected to the L-shaped water outlet pipe 8 through the filtering structure. One end of the L-shaped water outlet pipe 8 passes through the side wall of the water tank 1 and extends into the water tank 1. A plurality of L-shaped water outlet nozzles 14 are fixedly connected to the side wall of the L-shaped water outlet pipe 8. The plurality of L-shaped water outlet nozzles 14 are arranged in a vertical ring array.

[0026] See also Figure 1-3The automatic water replenishment structure includes a control panel 18, which is fixedly connected to the side wall of the water tank 1.

[0029] See also Figure 1-3 The filter box 9 is made of transparent material, which makes it easy to check the amount of impurities in the filter box 9.

[0030] The working principle of the present invention is as follows: the water amount in the water tank 1 can be detected by setting two liquid level sensors 15. When the water amount is lower than the lower liquid level sensor 15, the lower liquid level sensor 15 cannot detect the water level and will send a signal to the control panel 18. The control panel 18 controls the electric valve 16 to open, so that the water source enters the water tank 1 through the water inlet pipe 17.

Then the water flows into the L-shaped water outlet pipe 8, and finally through the L-shaped water outlet nozzles 14 arranged in a plurality of vertical ring arrays, the water in the L-shaped water outlet pipe 8 is sprayed out in a clockwise shape, thereby driving the water in the water tank 1 to surge, so that the water in the water tank 1 and the water after heat exchange are mixed and heated evenly, thereby improving the heating efficiency of the water in the water tank 1.
