The user connects the shaft joint 201 to the external body, the steam enters the steam head assembly 300 through the steam silicone tube 600, and the steam presses the steel balls 314 on both sides. On the upper side, the weight of the steel ball 314 and the compression force of the steel ball spring 315 Cooperating to offset the steam pressure, so that the upper side of the steel ball 314 sinks to seal the air outlet of the steam nozzle, which serves to seal the upper flow channel. At this time, the steam leakage of the upper flow channel is zero or negligible; at the same time, The pressure of the steel ball on the side of the steel ball and the accumulated pressure of the steam is greater than the compression force of the lower side ball spring, so that the lower side of the steel ball sinks, because the upper and lower faces of the ground brush body 100 are not connected to each other, when the steam is from the lower side of the pipe After the branch outlet is ejected, it will only enter the lower flow path of the ground brush body 100 from the square hole 121. In addition, the outside of the ground brush main body 100 may be covered with a rag (not shown), and the steam infiltrated rag contacts the ground.

When the reverse side of the ground brush is used, the body, the rotating shaft front bracket 203, the rotating shaft rear bracket 204, and the rotating shaft joint 201 are kept stationary, and the ground brush body 100 is rotated around the rotating shaft portion 205 in the Y-axis direction, so that the other side of the ground brush faces upward. By comparing the weight of the steel ball, the ball spring force and the steam pressure, the steam flows to the other side and flows into the upper flow path.

While using steam cleaning, a solution can be used, which can be water or even a detergent as needed. The solution enters the adapter 402 through the solution silicone tube 700. When the water pressure is greater than the compressive force of the shut-off valve spring 405, the solution is pressed to open the shut-off valve plug 404, and is sprayed from the solution nozzle 420 to the ground through the solution nozzle holder 401 to dissolve the stain, and then Use steam to clean up the stains.
