The second pontoon 6 here also moves in the axial direction of the receiving chamber 41. It should be noted that, since the linkage rod 62 is disposed through the second chamber 45, a certain gap exists between the bottom surface of the second chamber 45 and the linkage rod 62, and when water is drained, water in the second chamber 45 is drained through the gap.

The limiting mechanism comprises a first rotating part 8, the first rotating part 8 comprises a first rotating shaft part 81, a first supporting leg part 82 and a second supporting leg part 83, the first rotating shaft part 81 is used for being connected with two side walls of the accommodating cavity 41 and is arranged in a rotating mode relative to the accommodating cavity 41, the first rotating shaft part 81 is specifically located above the isolating plate 43 and is arranged in parallel with the isolating plate 43, and a groove matched with the first rotating shaft part 81 can be formed in the accommodating cavity 41. First leg 82 is the setting of U style of calligraphy, and one end is connected with first pivot portion 81, and the other end is the setting of spliced pole 821, and spliced pole 821 card is gone into to U type breach 511 for first leg 82 and the linkage of first flotation pontoon 5, spliced pole 821 are cylindrical setting.

The second leg portion 83 is provided with two connecting legs 831 and a second rotating member 9, one end of each of the two connecting legs 831 is connected to the first rotating shaft portion 81, and the other end of each of the two connecting legs 831 is connected to the second rotating member 9, so that the second rotating member 9 is rotatably disposed relative to the two connecting legs 831. Further, in order to limit the rotation effect of the second rotating component 9, the two connecting feet 831 are provided with limiting protrusions 832, and the limiting protrusions 832 limit the second rotating component 9 from rotating excessively, so as to achieve the position limiting effect of the second rotating component 9.

The second rotating member 9 is provided with a linking portion 91, a locking portion 92 and a gravity portion 93, the linking portion 91 is used for being connected with the two connecting pins 831 to form a relative rotation effect, the locking portion 92 is arranged in parallel with the first rotating shaft portion 81, the locking portion 92 is used for being matched with the hook portion 61 to achieve the locking effect, here, it should be noted that the downward surface of the locking portion 92 is an inclined surface, and the locking portion 92 is located in the axial vertical direction of the hook portion 61. The gravity portion 93 and the locking portion 92 are also disposed in parallel, and the weight of the gravity portion 93 is greater than the weight of the second rotating member 9 at any other position, and the gravity portion 93 is located at an end away from the second leg portion 83. Here, the gravity portion 93 is disposed toward the first float 5, and the limiting protrusion 832 is also located toward the first float 5 to limit the downward tilting of the gravity portion 93. In the normal state, the second rotating member 9 is always kept in a state of abutting against the limit projection 832 due to the arrangement of the gravity portion 93 and the limit projection 832.

With the arrangement of the first rotating member 8, in the first state, the locking portion 92 is not engaged with the hook portion 61, and only in the second state, because the first float 5 rises, the force in the axial direction is converted into the radial rotating force of the first rotating member 8, so that the locking portion 92 rotates, the hook portion 61 exceeds the height of the locking portion 92, and due to the gravity effect of the gravity portion 93, the locking portion 92 is rapidly returned to the initial position, and at this time, the locking portion 92 is engaged with the hook portion 61, thereby achieving the locking effect.

Further, still include relief valve 10, relief valve 10 is connected with first pipe 11, adopts the setting of relief valve 10, prevents that internal pressure is too big, influences the effect of washing by water, through control relief valve 10, carries out the pressure regulating and sets up. Its concrete structure is equipped with second spring 101 and end cap 102 in the relief valve 10, and under normal condition, end cap 102 seals being connected of relief valve and first pipe 11, and is too big when the inside pressure of first pipe 11, can promote end cap 102 motion, and partial pressure can discharge through relief valve 10, and at this moment, second spring 101 compresses. When the air pressure returns to the normal state, the second spring 101 is reset, so that the plug 102 performs the connection of the closed pressure relief valve 10 and the first conduit 11.

In the first state, i.e. when there is no water in the water tank or there is no water in the water tank, the first float 5 and the second float 6 are fixed in the corresponding chambers and do not operate, and the locking portion 92 and the hook portion 61 are not locked in cooperation. At this time, the shielding member 64 on the first water tank 63 shields the nozzle 111, so that the nozzle 111 is isolated from the second pipe 12, and the venturi ejector 1 does not operate.

When water is initially supplied to the water tank, the water inlet valve 32 is opened, and external water is introduced into the water tank through the water inlet pipe 31 and the first guide pipe 11, and the water is retained in the water tank because the nozzle 111 is shielded by the shield member 64. As the water level gradually rises, when the water level exceeds the first water inlet 441, water enters the first chamber 44, the first buoy 5 moves upwards along the axial direction of the inner wall of the first chamber 44, water enters the second chamber 45 from the bottom surface of the second chamber 45, and the second buoy 6 also moves upwards. It is to be noted here that the floating speed of the first float 5 exceeds the floating speed of the second float 6, thereby ensuring that the lock portion 92 is always located above the catch portion 61. The water continuously enters the two chambers, and when the water level exceeds the second water inlet 451, the water in the second chamber 45 can enter the first chamber 44 through the separation plate 43, so that the whole water level is equal.

When the water in the water tank is nearly full, the first rotating member 8 moves upward along with the first buoy 5, the first rotating member 8 rotates, and the second rotating member 9 does not rotate due to the action of the gravity part 93. The second float 6 moves axially upward to push open the locking part 92 on the second rotating member 9, so that the hook part 61 exceeds the locking part 92, and at this time, due to the action of the gravity part 93, the second rotating member 9 is quickly reset, and the locking part 92 is locked and matched with the hook part 61. It should be noted here that, along with the axial upward movement of the second float 6, the first water tank 63 also moves axially upward, and when the second float 6 and the first float 5 are locked, the third float 2 also reaches the preset value, so that the water inlet valve 32 stops working, the shielding piece 64 on the first water tank 63 moves, the shielding effect on the nozzle 111 is removed, and at this time, the drainage button is pressed, and the venturi ejector 1 works, so that the drainage effect can be realized.

When the water is drained, the water level in the water tank rapidly drops, the float bowls in the two chambers drop along with the water level, the locking part 92 and the clamping hook part 61 are unlocked and matched in the process that the first float bowl 5 drops, and meanwhile, the first water tank 63 moves downwards to drive the shielding piece 64 to shield the nozzle 111 again. When the water level of the water tank drops, the third buoy 2 drives the water inlet valve 32 to work, the water adding operation is started, and the water storage operation is restarted when the shielding piece 64 shields the nozzle 111 again because the water discharging speed is higher than the water inlet speed.
