The washing machine is an indispensable household appliance in daily life. Taking a drum washing machine as an example, an inner drum filled with clothes is driven to rotate by a motor, washing water is driven to circularly flow by a pump in the process, and the clothes are continuously stirred by circulating water, so that the clothes are cleaned. In the washing process, the clothes rub against each other, and thread scraps such as cotton fibers and the like inevitably fall off in water, and if the filtering is not carried out, the thread scraps can adhere to the surfaces of the clothes, so that the secondary pollution of the clothes is caused.

The existing washing machine, no matter in impeller type or drum type, can be provided with a filter screen for intercepting and filtering thread scraps in the water circulation process. For the pulsator washing machine, a pocket type filter screen is generally disposed on a sidewall of the drum to filter the lint when the circulating water enters the drum. In the drum washing machine, a filter net is usually disposed outside the inner drum to filter lint in the circulating water.

The existing filter screen has the problem that the filter screen is easy to block while playing a role in intercepting thread scraps, so that the filter effect is influenced, and great troubles are brought to users.
