Referring to FIGS. 5 and 6, the residual liquid discharge passage 4 includes a first passage 41 communicating with at least one residual water hole 21111, and a second passage 42 having one end communicating with the first passage 41 and the other end communicating with the outer cylinder of the washing machine. The mass 5 is slidably disposed in the first passage 41.

In this embodiment, the mass 5 is gap-fitted with the first passage 41, and the mass 5 is cylindrical or spherical. In this embodiment, the mass 5 is spherical. One end of the first passage 41 near the second passage 42 is a circular hole adapted to the mass 5, and the first passage 41 and the second passage 42 form a stepped residual liquid discharge hole. Optionally, the maximum width of the residual liquid discharge hole in the second passage 42 is smaller than the maximum width of the residual liquid discharge hole of the first passage 41, and the diameter of the mass 5 is smaller than the residual liquid discharge hole in the second passage 42. The maximum width is such that the weight 5 cannot pass through the residual liquid discharge hole of the second passage 42 and is always placed in the residual liquid discharge hole of the first passage 41. One end of the first passage 41 connecting the residual water hole 21111 forms a support surface 411 with the outer wall of the detergent box body 21, so that the mass 5 can only have residual liquid of the first passage 41 between the support surface 411 and the second passage 42. The discharge hole reciprocates and slides.

During the working vibration of the washing machine, the mass 5 reciprocates in the Z direction along the Z in the first passage 41 as the vibration of the washing machine moves, and the liquid remaining in the drop box 211 passes through the mass 5 through the reciprocating movement of the mass 5 The gap between the first passages 41 is forced into the second passage 42 and enters the outer cylinder of the washing machine.

One end of the second passage 42 connected to the first passage 41 is provided with a tapered groove 421 adapted to the mass 5, and the first passage 41 and the second passage are disposed when the mass 5 is placed in the tapered groove 421. The disconnection of 42 prevents the liquid in the outer cylinder of the washing machine from entering the first passage 41 through the second passage 42 and flowing back into the drop box 211; and at the same time, the detergent can be prevented from leaking when the washing machine is not activated or the vibration is extremely small.

Optionally, an end of the first passage 41 adjacent to the detergent receiving space 2 is provided with a first one-way valve (not shown), and the spring 6 is disposed between the one-way valve and the mass 5 In the first passage 41, a second one-way valve (not shown) is also disposed at an end of the second passage 42 away from the first passage 41. By providing the two check valves, the liquid can only be along In the figure, Z flows in the direction indicated by the arrow and cannot be reflowed.

As shown in Fig. 5, when the washing machine is not vibrating, the mass 5 is placed in the tapered groove 421 due to the gravity action of the mass 5 itself and the gravity of the residual liquid in the first passage 41. When the washing machine starts to work and generates vibration, when the mass 5 vibrates in the opposite direction of the direction indicated by the Z arrow, the pressure in the first passage 41 is increased due to the action of the first one-way valve in the first passage 41, The action of the second one-way valve in the second passage 42 causes the pressure in the second passage 42 to decrease, so that the residual liquid in the first passage 41 is forced through the gap between the mass 5 and the first passage 41. The second passage 42 enters the outer cylinder of the washing machine to improve the drainage effect.

When the mass 5 vibrates in the direction indicated by the Z arrow, the residual liquid enters the first passage 41 due to the action of the first one-way valve, and the second passage 42 communicates with the outer cylinder of the washing machine, and the residual gravity of the liquid itself and the vibration of the washing machine Under the force generated, the residual liquid will enter the second passage 42 through the gap between the mass 5 and the first passage 41 and enter the outer cylinder of the washing machine.
