As shown in the drawings, the reset mechanism 18 is preferably a torsion spring, and includes an elastic body 181 and a handle 182, when the elastic body is in a natural state, the handle 182 defines a receiving portion that is in snap fit with the positioning mechanism 17, when the operating lever drives the upper connecting portion to rotate around the pivot axis a2, under the limiting effect of the protrusion 1422a of the lower connecting portion, the handle 182 is opened towards the rotating direction, and the elastic body 181 is elastically twisted, which makes the upper connecting portion rotate around the pivot axis a2 in a rebounding manner. The elastic body 181 has a large stiffness coefficient so that the upper connection portion can rotate no more than 180 degrees.

Fig. 20 is a schematic view of cleaning of a steam cleaning device according to an embodiment of the present invention in a short side direction (indicated by an arrow) of the first (1322) or second cleaning surface (1322'). As shown in fig. 20, the cleaning head is applied with force in the short side direction of the first or second cleaning surface by the operating lever to clean the surface to be cleaned, and the angle between the axis of the operating lever and the axis a1 can be changed while cleaning by the pivoting axis a1 between the lower connecting head and the cleaning head, which can be adapted to the heights of different users, so it can achieve easy cleaning without stooping to operate the steam mop. Meanwhile, due to the existence of the first stop surface, the included angle between the axis of the operating rod and the axis A1 along the short-side cleaning direction is not less than 90 degrees, which avoids the situation that the force applied to the operating rod can not advance the cleaning head.

Fig. 21 is a schematic view of the cleaning of the steam cleaning device according to an embodiment of the present invention along the long side direction (shown by an arrow) of the first (1322) or second cleaning surface (1322'). As shown in fig. 21, the cleaning head is applied with force along the long side direction of the first or second cleaning surface by the operating lever to clean the surface to be cleaned, and the angle between the axis of the operating lever and the axis A2 can be changed while cleaning by the pivoting axis A2 between the upper connecting head and the cleaning head, which can be adapted to the heights of different users, so it can achieve easy cleaning without stooping to operate the steam mop. Meanwhile, due to the existence of the third and fourth stop surfaces, the included angle between the axis of the operating rod and the axis A2 along the long-edge cleaning direction is not more than 180 degrees, so that the situation that the force applied to the operating rod cannot advance the cleaning head is avoided.

In summary, it is readily understood by those skilled in the art that the advantageous modes described above can be freely combined and superimposed without conflict.

The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
