[0024] The excess heat generated by the combustion of the boiler body 6 enters the interior of the waste heat tank 23 through the through hole 24. At the same time, water is injected from one end of the heat pipe 26 and discharged from the other end through the heat pipe 26. The water flow inside the heat pipe 26 transfers the heat inside the waste heat tank 23 to the water flow through the heat pipe 26.

[0025] The filter assembly 3 includes a forward and reverse screw rod 31, a knob 32 is fixedly installed on the outer surface of one end of the forward and reverse screw rod 31, a Z-shaped rod 33 is threadedly connected to the outer surface of the forward and reverse screw rod 31, a mounting bracket 34 is fixedly installed on the outer surface of one side of the Z-shaped rod 33, a filter screen 35 is fixedly installed on one side of the mounting bracket 34, a filter tube 36 is slidably installed on the outer wall of the filter screen 35, the forward and reverse screw rod 31 is rotatably connected to the inner wall of one side of the base 21, the Z-shaped rod 33 slides on the outer wall of the groove 22, the inner surface of the filter screen 35 is attached to the side of the filter tube 36, the filter tube 36 is fixedly installed on the upper outer surface of the heat-insulating shell 1, and the upper outer surface of the filter tube 36 is attached to the lower outer surface of the waste heat box 23 and is located directly below the through hole 24;

[0026] By turning the knob 32, the forward and reverse screw rods 31 rotate, and the rotation of the forward and reverse screw rods 31 drives the two Z-shaped rods 33 threadedly connected on their outer surfaces to move relative to each other, thereby driving the filter screen 35 fixedly mounted on one side of the mounting frame 34 to slide on the inner wall of the filter tube 36.

[0027] The heat conducting pipe 26 is provided with a water inlet end and a drainage end, and the outer wall of the water inlet end and the outer wall of the drainage end both pass through the upper inner wall of the waste heat box 23 .

When the filter screen 35 needs to be replaced or cleaned, the knob 32 is turned to drive the forward and reverse screw rods 31 to rotate. The rotation of the forward and reverse screw rods 31 drives the two Z-shaped rods 33 threadedly connected on its outer surface to move to both sides, thereby driving the filter screen 35 fixed on one side of the mounting frame 34 to slide out of the inner wall of the filter tube 36, and then the filter screen 35 can be replaced or cleaned.
