The one-way valve 5 is selected according to actual conditions, and the one-way valve 5 can be fixed in a clamping or bonding mode, or can be made of materials such as plastics or rubber; the filter screen 7 can be fixed by adopting an integral vulcanization or bonding mode.

In this embodiment, the impeller 2 rotates to drive the collection cylinder 3 to rotate, water in the cleaning barrel 1 enters the collection cavity 4 from the one-way valve 5 under the action of centrifugal force, then flows out from the water outlet 6, and passes through the filter screen 7 when flowing out, and after the water flows through the filter screen 7, the thread scraps in the water are left on the filter screen 7, and cannot be brought back into the cleaning barrel 1. When the impeller 2 rotates normally, water in the cleaning barrel 1 enters the collecting cavity 4 downwards and then flows out of the water outlet 6 under the influence of centrifugal force, but when the impeller 2 stops rotating suddenly, the water in the collecting cavity 4 can flow back into the cleaning barrel 1 from bottom to top, and in order to avoid bringing the thread scraps in the collecting cavity 4 back into the cleaning barrel 1, a one-way valve 5 is arranged, so that the water in the collecting cavity 4 cannot flow back into the cleaning barrel 1 from bottom to top; the check valve 5 can also enable water flow in the cleaning barrel 1 to orderly flow into the collecting cavity 4, so that the water in the collecting cavity 4 is prevented from being disturbed by the water flow in the cleaning barrel 1 to form turbulence, and the filtering effect is further affected.

After the clothes are washed, under the impact of water flow, the rotating shaft 10 rotates to the outer side of the collecting cavity 4, and drives the one-way valve 5 to restore to the state before rotation.

In the scheme, the check valve uses two approximately semicircular plates as the check valve 5 to control water in the cleaning barrel 1 to flow into and out of the collecting cavity 4, compared with other modes, the structure of the scheme is simplest, the control is easy, and the later disassembly and maintenance are convenient; although a clearance needs to be left between the two straight sides 8 for the two one-way valves 5 to rotate normally, the clearance can be controlled to be relatively narrow, so that the water flow into and out of the collecting cavity 4 is hardly affected; the size of the water inlet gap can be adjusted according to actual conditions, so long as water flow can smoothly enter the cleaning cavity 4.

Further, as shown in fig. 3-4, in this embodiment, in order to avoid that after the pulsator 2 suddenly stops rotating, the water in the collecting cavity 4 pushes the curved edge 9 to rotate towards the outer side of the collecting cavity 4, which affects the collection of lint and the normal cleaning of clothes, the lint collecting device further includes: an upper limit element 11 is arranged on the collecting cylinder 3 and is positioned above the straight edge 8 and/or the curved edge 9, and is used for preventing water in the collecting cavity 4 from flowing back into the cleaning barrel 1 through the collecting cylinder 3 after the curved edge 9 rotates to the outer side of the collecting cylinder 3.
