Fig. 11 is a schematic view 1 illustrating a movement state of the stem in the first embodiment.

As shown in fig. 11, when the sealing ring 48 is controlled to be at the blocking position, the upper end of the hook 57 is located at the point M of the second limiting portion, and at this time, the sealing ring 48 is located in the annular groove 33, the water flow between the first passage 25 and the second passage 30 is blocked, and the water in the bucket 11 cannot be directly discharged into the sewer pipe 90 through the second passage 30.

When the snap cap 45 is snapped, the sealing ring 48 and the valve core rod 53 move downward, and at this time, the upper end of the hook 57 enters the upper end (i.e., point H) of the fourth slide way 61d from the point M of the second limit portion along the third slide way 61 c. Once the snap cap 45 is released, the valve core rod 53 moves upward under the elastic force of the return spring 56, and the upper end of the hook 57 enters the lower end of the first slide way 61a (i.e., the point L of the first limit portion) along the fourth slide way 61 d.

Fig. 12 is a schematic view 2 showing the movement state of the stem of the first embodiment.

As shown in fig. 12, when the upper end of the hook 57 is located at the point L of the first position-limiting portion, the sealing ring 48 is lifted from the position of the ring groove 33 to the first passage 25, so that the water in the bucket 11 can be drained from the first passage 25 into the sewer pipe through the second passage 30, that is, the sealing ring 48 is controlled to be at the conducting position.

Next, when the snap cap 45 is snapped again, the sealing ring 48 and the valve core rod 53 move downward, and during the downward movement, the sealing ring 48 abuts against the inner side surface of the second channel wall, so that the edge portion of the sealing ring 48 contracts, and at the same time, the upper end of the hook 57 enters the upper end (i.e., point H') of the second slide channel 61b along the first slide channel 61a from the point L of the first limit portion. Once the snap cap 45 is released, the valve core rod 53 moves upward under the elastic force of the return spring 56, and the upper end of the hook 57 enters the lower end of the third slide way 61c along the second slide way 61b (i.e. the point M of the second limit portion), at this time, the sealing ring 48 enters the annular groove 33 and is unfolded, i.e. the sealing ring 48 is controlled to the blocking position again, so that the water flow between the first passage 25 and the second passage 30 is blocked.

When the bucket device 10 needs to store water, the water bucket 11 can store water only by controlling the sealing ring 48 at the cut-off position to prevent the water in the bucket 11 from directly flowing out from the first channel 25 and the second channel 30.

In addition, the bucket device 10 also has an anti-overflow function when storing water, specifically as follows:

according to the principle of communicating vessels, the water in the water bucket 11 is equal to the water in the third channel 35 in height, the water level in the third channel 35 rises along with the increase of the stored water in the water bucket 11, when the water level rises to the position of the overflow inlet 37, the water directly enters the second channel 30 through the overflow pipe 43 and is finally discharged out of the sewer pipe 90, and therefore the water is prevented from overflowing the water bucket 11.

Effect of the first embodiment

According to the drainer and the drainer in accordance with the embodiment, the drainer is installed on the sidewall of the bucket and corresponds to the water outlet of the bucket, so that the drainer does not occupy the space below the bucket. Further, since the drainer has a bouncing spool member, wherein the bouncing spool member includes: the bouncing control piece which passes through the first channel part and is arranged at the second channel part can be installed in a picking and placing mode through the valve rod, therefore, when water flow in the water bucket needs to be cut off or conducted, a user only needs to press the valve rod without contacting water in the water bucket, and in addition, when the drainer is blocked, the user only needs to take out the bouncing valve core component, and the drainer can be dredged.

In addition, since the drainer further comprises the third channel part provided with the overflow inlet and the bypass type overflow preventing channel part in the first embodiment, when the water level in the third channel exceeds the overflow inlet, the water flow can directly flow into the sewer pipe through the overflow preventing channel part, so that the overflow of the water from the water bucket is prevented.

In addition, in the first embodiment, the edge part is arranged on the outer side of the bucket, the channel hole is formed in the edge part, and the valve rod penetrates through the channel hole, the third channel part and the first channel part and is installed in the second channel part, so that a user can conveniently cut off or conduct water flow in the bucket by using the valve rod.

In addition, in the first embodiment, the bouncing spool member further comprises a snap cap arranged at the upper end of the valve rod, and the snap cap is provided with a threaded rod and a matched locking nut, so that a user can adjust the height of the snap cap relative to the valve rod by adjusting the position of the locking nut on the threaded rod.
