[0043] Working principle: First, by installing the cover body 1 inside the washing machine through the limit block 7, when there are fewer clothes to be washed, the electric telescopic column 202 drives the limit plate 203 to move inside the fixed frame 201, so that the limit plate 203 drives the sealing plate 9 to move on the surface of the fixed pipe 8, so that the rear side of the sealing plate 9 is in close contact with the surface of the first water outlet pipe 13, so that the sealing plate 9 can seal the surface of the first water outlet pipe 13, so that the air pressure inside the fixed pipe 8 is sealed, and then the washing water passes through the inside of the water inlet tank 4, and the filter 3 filters the washing water, so that the filter 3 filters out the debris inside the washing water, and prevents the debris from entering the inside of the water inlet pipe 15. Blocked, and then the cleaning water enters the interior of the fixed pipe 8 through the water inlet pipe 15, and the pressure pump 10 pressurizes the interior of the fixed pipe 8 through the connecting pipe 12, so that the water pressure inside the fixed pipe 8 remains stable, and the cleaning water enters the interior of the second water spray port 5 through the second water outlet pipe 14, and can be sprayed out from the second water spray port 5, thereby achieving a good cleaning effect on the clothes, and solving the problem that the position height of the water spray port on the surface of the return cover plate of most existing washing machines is unchanged, but the number of clothes washed each time is the same. When the number of clothes washed is small, the height difference between the water sprayed from the water spray port and the clothes is large, which will affect the impact force of the water circulation on the clothes, and cannot achieve a good cleaning effect on the clothes.
