When the washing begins, the valve can be opened, and after the squeezing part 2 discharges the air in the flexible washing barrel 1 in the squeezing process, the valve is closed, so that the squeezing washing effect is improved. And because the top of the squeezing part 2 is lower than the center of the flexible washing tub 1, in the squeezing process of the squeezing part 2 to the flexible washing tub 1, the washings at the lower part in the flexible washing tub 1 are forced to move to the upper part in the flexible washing tub 1, in the process of releasing the squeezing of the squeezing part 2 to the flexible washing tub 1, the washings moving to the upper part tumble and fall to the lower part in the flexible washing tub 1 again, and in the falling process, the shape of the flexible washing tub 1 is changed to the state when the washings are not squeezed by the squeezing part 2 at first.

In the whole washing process, the extrusion part 2 of the washing equipment realizes washing by extruding the flexible washing barrel 1, the acting force is transmitted to the washings in the flexible washing barrel 1 through the flexible washing barrel 1, the extrusion part 2 is not in direct contact with the washings, and the flexible washing barrel 1 is made of flexible rubber or flexible silica gel materials, so that the washings are not damaged rigidly in the washing process, and the washings are less worn.

The utility model is also provided with an elastic action part 4, which can effectively avoid the over-tight extrusion of the washings in the extrusion washing process. The utility model is also provided with a pressure sensor, and the extrusion pressure degree of the extrusion part 2 to the flexible washing barrel 1 can be conveniently adjusted by detecting the extrusion force of the extrusion part 2 to the washing.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments.
