Specifically, because the middle connection portion 242 penetrates through the first sealing ring 26, and the diameter of the inner sealing portion 243 is greater than that of the middle connection portion 242, when the valve core 24 is at the initial position, the first sealing ring 26 can elastically abut against the inner sealing portion 243, so that the inner sealing portion 243 and the first sealing ring 26 jointly cut off the water inlet cavity 231 and the water outlet cavity 232, and thus the sealing fit between the valve core 24 and the first sealing ring 26 is more direct and reliable, and the structural reliability of the valve core 24 can be improved.

Furthermore, the outer pressing portion 241 is disposed outside the valve housing 23, when a user wants to apply an acting force to the check valve 20, so that the water outlet pipe assembly 100 discharges water, the middle connecting portion 242 and the inner sealing portion 243 below the outer pressing portion 241 can move downward by pressing the outer pressing portion 241 outside the valve housing 23 downward, so that the inner sealing portion 243 is away from the first sealing ring 26, and the water inlet cavity 231 and the water outlet cavity 232 are communicated with each other, which not only makes the structure of the valve core 24 simpler, but also makes the movement of the valve core 24 smoother and more stable, prevents the valve core 24 from being stuck when moving, and thus can further improve the structural reliability of the check valve 20.

In addition, the elastic member 25 is connected between the valve housing 23 and the outer pressing portion 241, and when a user presses the outer pressing portion 241 downwards, the elastic member 25 can be squeezed between the outer pressing portion 241 and the valve housing 23 to deform, so that after the user removes the external force, the elastic member 25 drives the outer pressing portion 241 to move upwards, the valve core 24 is reset, and the reliability of the elastic member 25 can be further improved.

As shown in connection with fig. 3, the middle connection portion 242 may mainly include: a first connection section 2421 and a second connection section 2422, the first connection section 2421 is connected between the outer pressing portion 241 and the second connection section 2422, the second connection section 2422 is further connected to the inner sealing portion 243, the diameter of the second connection section 2422 is smaller than that of the first connection section 2421 and that of the inner sealing portion 243, and the second connection section 2422 penetrates through the first sealing ring 26. Specifically, by connecting the first connection section 2421 between the outer pressing part 241 and the second connection section 2422 and connecting the second connection section 2422 between the first connection section 2421 and the inner sealing part 243, setting the diameter of the second connection section 2422 to be smaller than the diameter of the first connection section 2421 and the diameter of the inner sealing part 243, and penetrating the second connection section 2422 through the first sealing ring 26, the first connection section 2421 can be tightly attached to the upper end of the valve housing 23, so that on the premise of ensuring that the second connection section 2422 smoothly penetrates the first sealing ring 26, water is prevented from leaking from between the first connection section 2421 and the upper end of the valve housing 23, causing water leakage of the fabric cleaning machine 1000, and thus, the structural reliability of the check valve 20 can be further improved.
