[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 The steam pipe 2 and the thermal storage generator 3 are both provided with a ventilation and heating mechanism 10, which includes a supporting breathable mesh plate 101. The lower horizontal part of the steam pipe 2 is fixedly connected to a delivery pipe 102, and the inner wall of the delivery pipe 102 is rotatably connected to a T-shaped tube 103. The outer side of the vertical part of the T-shaped tube 103 is fixedly sleeved with a gear 104. A servo motor 105 is fixedly installed on the inner bottom of the thermal storage generator 3. A limiting ring groove 107 is provided on the inner wall of the thermal storage generator 3.

[0024] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 A plurality of nozzles are fixedly connected to the upper side of the horizontal portion of the T-tube 103.

When the T-tube 103 rotates, it can drive the limiting ball 108 to rotate along the inner wall of the limiting ring groove 107, and limit the rotation of the T-tube 103, so that the T-tube 103 is in a stable rotation state.
