[0002] Microplastic fibers are plastic particles with a diameter of less than 5 mm and are also a major carrier of pollution. As an emerging environmental pollutant, microplastic fibers have attracted increasing attention worldwide. Microplastics are small in size, which means a higher specific surface area (specific surface area refers to the surface area per unit mass of porous solid materials). The larger the specific surface area, the greater the ability to adsorb pollutants. Microplastic fibers are also a factor in water pollution. The increase in microplastic fibers in water sources comes in part from wastewater discharged from household appliances.

The filter assembly 120 is arranged in the accommodating cavity of the shell 110, and is used to collect microplastic fibers in the water entering from the water inlet. The filtering accuracy of the filter assembly 120 is 50μm, so microplastic fibers larger than 50μm in the drainage filter device can be filtered.

[0026] The filter assembly 120 includes a handle 121, a filter body 123, a filter screen 124 and a filter element support 125. The first sealing ring 122 and the second sealing ring 126 are respectively provided on the outer circumference of both ends of the filter body 123, and the filter body 123 is sealed and connected to both ends of the housing 110 through the first sealing ring 122 and the second sealing ring 126. The first sealing ring 122 seals the gap between the handle 121 and the filter body 123 to prevent water from flowing to the outside of the washing machine; the second sealing ring 126 is provided with a circumferential groove on the inner side, and the groove edge of the second sealing ring 126 abuts against one end of the filter element support 125 away from the first sealing ring 122 to prevent the filter element support 125 from falling from the open end of the filter body 123.

[0027] A detachable filter screen 124 is provided in the filter body 123, and the filter screen 124 is sleeved on the outer surface of the filter element bracket 125. The filter screen 124 is sleeved on the outer surface of the filter element bracket 125, and the filter screen 124 is placed in the cavity of the filter body 123. An internal thread is provided on the inner wall near the open end of the housing 110, and the filter assembly 120 is threadedly fixed to the housing 110.

[0028] The filter body 123 is provided with a handle 121 at one end away from the second sealing ring 126. A bayonet is provided at intervals at the position where the filter body 123 contacts the handle 121. The handle 121 is provided with a corresponding buckle, and the buckle is fixedly engaged with the bayonet. Preferably, four bayonet are evenly spaced at one end of the filter body 123 in the circumferential direction, and four corresponding buckles are also provided.

[0029] The steps for assembly are as follows:

[0030] The first step is to fix the first sealing ring 122 on the outer circumference of one end of the filter body 123;

[0031] Step 2: Fix the handle 121 to one end of the filter body 123 by snapping;

[0032] Step 3: Put the filter screen 124 on the outer surface of the filter element bracket 125, and then put the whole into the cavity of the filter body 123;

[0033] Step 4: a second sealing ring 126 is arranged on the outer circumference of one end of the filter body 123 away from the first sealing ring 122;

[0034] Step 5: Fix the assembled filter assembly 120 in the housing 110 by means of threads.

[0035] It should be noted that the utility model also protects a washing machine containing the drainage filter device for the washing machine, the washing machine includes a washing machine body, specifically, the washing machine body is provided with the drainage filter device for the washing machine, the drainage filter device is arranged on the upper front surface of the washing machine body and is located downstream of the drainage pump in the washing machine body. A handle 121 of the filter assembly 120 is exposed on the outer surface of the washing machine body, so that the user can clean or replace the drainage filter device through the handle 121.

[0036] like Figure 3 As shown, the water inlet is arranged at one axial end of the housing 110, and the water outlet is arranged on the radial side of the housing 110.
