As shown in fig. 6 to 8, the buoyancy control assembly 40 further includes a water sealing rod 44, a first water leakage hole 422 is provided at the lower portion of the switching cup 42, one end of the water sealing rod 44 is in linkage fit with the full-row starting switch of the water tank 10 through a connecting rod 60, and the other end is in opening and closing fit with the first water leakage hole 422. Wherein the sealing rod 44 and the float 41 are rotatably hinged in the switching cup 42 by a latch, or the sealing rod 44 may be rotatably attached to a drain valve or other fixing member in the water tank. Preferably, the water sealing rod 44 is disposed at the bottom of the water storage cavity 421.
In this embodiment, specifically, in the first buoyancy state, the water sealing rod 44 closes the first water leakage hole 422, the float 41 in the switching cup 42 is in a floating state and closes the ventilation channel 22, when the half-drain starting switch controls the drain valve 50 to open the drain port 11, the water in the first water cavity 20 is maintained, and the water in the second water cavity 30 is released from the drain port 11, so as to realize half-drain; in the second buoyancy state, the water sealing rod 44 is driven by a full-row starting switch to open the first water leakage hole 422, the float 41 in the switching cup 42 falls down and opens the ventilation channel 22, and when the full-row starting switch controls the water draining valve 50 to open the water draining port 11, water in the first water cavity 20 and the second water cavity 30 is released from the water draining port 11, so that full water draining is realized.
In addition, this embodiment still has the function of holding back breath when half drainage, and its realization mode can adopt:
1. when the water sealing rod 44 closes the first water leakage hole 422, the water sealing rod 44 does not form a seal with the first water leakage hole 422, and water in the switching cup 42 can leak from the first water leakage hole 422 by a small amount; thus, when the water tank 10 is half-discharged, the water in the switching cup 42 can slowly leak out through the first water leakage hole 422, so that the float 41 can also fall down, and the air passage 22 is opened by the float 41, so that the first water cavity 20 is not suffocated when the water tank 10 is re-filled.
2. When the water sealing rod 44 closes the first water leakage hole 422, the water sealing rod 44 and the first water leakage hole 422 form sealing fit; the switching cup 42 is further provided with a second water leakage hole 423, and when the water sealing rod 44 closes the first water leakage hole 422, water in the switching cup 42 can leak from the second water leakage hole 423 by a small amount; thus, when the water tank 10 is half-discharged, the water in the switching cup 42 can be slowly leaked through the second water leakage hole 423, so that the float 41 can also fall, and the air passage 22 is opened by the float 41, so that the first water cavity 20 is not suffocated when the water tank 10 is re-charged.
3. A combination of the embodiments 1 and 2 may be adopted, that is, the sealing rod 44 does not form a seal with the first water leakage hole 422, and the switching cup 42 is further provided with the second water leakage hole 423, which can also achieve the anti-holding effect during semi-drainage. Preferably, the second water leakage hole 423 is smaller than the first water leakage hole 422.
It can be appreciated that, in the present invention, since the air passage 22 is opened by the float 41 when the water is completely discharged, the first water chamber 20 is not suffocated when the water tank 10 is re-filled after the water is completely discharged.
The working process of the double-exhaust control mechanism of this embodiment is briefly described as follows:
as shown in fig. 6, when the water tank 10 is full of water, the buoyancy control module 40 is in the state of fig. 4, the water storage chamber 421 of the switching cup 42 is immersed in water, one end of the water sealing rod 44 seals the large water leakage hole 422, the buoyancy chamber 411 of the float 41 is immersed in water to be in the floating state as shown in the drawing, and the other end of the lifting rod 43 of the float 41 is in the pressing state, so that the sealing gasket 431 on the lifting rod 43 is tightly attached to the upper end surface of the ventilation channel 22, and the upper end of the ventilation channel 22 is in the sealing state.
As shown in fig. 7, when the half-drain starting switch is started, the drain outlet 11 is opened, the buoyancy control assembly 40 is still in the state shown in fig. 4, the ventilation channel 22 at the upper part of the first water cavity 20 is in a closed state, so that when the drain outlet 11 is opened, the water in the second cavity 30 descends and is discharged, and the first cavity 20 is in a closed state, the water cannot be discharged under the action of atmospheric pressure, so that the water in the first cavity 20 is kept in the first cavity 20, and half-drain is realized.
As shown in fig. 8, when the full-row starting switch is started, the water outlet 11 is opened, the buoyancy control assembly 40 is in the state shown in fig. 5, one end of the water sealing rod 44 is lifted up under the driving of the full-row starting switch, the other end is separated from the large water leakage hole 422, water in the switching cup 42 rapidly flows away from the water storage cavity 421, the buoyancy cavity 411 is exposed out of the water surface, the float 41 swings downwards under the action of gravity, the sealing gasket 431 at the other end of the lifting rod 43 connected with the float 41 is separated from the ventilation channel 22, and the upper end and the lower end of the ventilation channel 22 are communicated, so that the upper ventilation channel 22 of the first water cavity 20 is in the opened state, and the water in the first water cavity 20 and the second water cavity 30 is simultaneously discharged in a descending manner, thereby realizing full-row drainage.
Second embodiment (when semi-draining, the first water leakage hole is opened by the water sealing rod, and the ventilation channel is closed by the lifting rod)
As shown in fig. 9 to 10, the main difference between the present embodiment and the first embodiment is that: in this embodiment, when the buoyancy control assembly 40 is in the first buoyancy state, the float bowl is in a 41-falling state and closes the ventilation channel 22, and correspondingly, when the buoyancy control assembly 40 is in the second buoyancy state, the float bowl is in a 41-floating state and opens the ventilation channel 22.
