The flushing-assisting water inlet valve 50 adopts the structure, is ingenious in design and easy to control. Of course, in other embodiments, the configuration of the flush-assist water inlet valve 50 is not so limited.

Further, in this embodiment, the tank inlet valve 60 includes a second valve housing 61 and a second water-stop diaphragm 62, the second water-stop diaphragm 62 correspondingly communicates with the water inlet channel 801 and the water outlet of the tank inlet channel 803, and encloses with the second valve housing 61 to form a second back pressure chamber 601, and the second valve housing 61 is provided with a second pressure relief hole 63 communicating with the second back pressure chamber 601. The water tank inlet valve 60 and the flushing-assisting inlet valve 50 adopt a back pressure cavity type control structure, and are easy to control and simple in structure.

The second pressure release hole 63 is controlled to be opened/closed by the float assembly 70, so that the tank inlet valve 60 can be automatically controlled by the change of the water level, and a delayed opening mode is also provided. When washing promptly, can open earlier and help towards water inlet valve 50, make the water in the inlet channel 801 flow out earlier from helping the bath passageway 802 and spray and wash (the water in the water tank also can realize normal drainage through opening of hydraulic pressure drain valve this moment), treat that the water level in the water tank triggers the motion of keg float subassembly 70 when falling to a take the altitude, and then relieve the shutoff to second pressure release hole 63, the water in the second back pressure chamber 601 is discharged from second pressure release hole 63, thereby open the water mouth of crossing between inlet channel 801 and the water tank inlet passageway 803, the water of inlet channel 801 flows into the water tank through water tank inlet passageway 803, thereby realize the moisturizing. When the water tank is replenished with sufficient water, the water level rises, and the floating barrel assembly 70 is driven to act, so that the floating barrel assembly 70 blocks the second pressure relief hole 63 again, and the entering water flow is stopped.

More specifically, referring to fig. 5 and 6, the float assembly 70 includes a body 71, a water inlet float 72, a small float 73, and a water stop lifting lever 74, the body 71 is fixed to the water inlet main body 80, and is provided with a water storage chamber 711 and a bottom drain hole 712 communicating with the water storage chamber 711, the small float 73 is disposed below the bottom drain hole 712, when the water level is at a high level (for example, when the water tank is full of water), the small float 73 always blocks the bottom drain hole 712 through buoyancy, water in the water storage chamber 711 cannot be discharged, when the water level drops to a level that cannot provide enough buoyancy for the small float 73, the small float 73 opens the bottom drain hole 712, and water in the water storage chamber 711 starts to be discharged.

The water inlet floating barrel 72 is arranged in the water storage cavity 711, the middle position of the water stopping lifting lever 74 is hinged to the water inlet main body 80, the first end of the water stopping lifting lever 74 is connected with the water inlet floating barrel 72, the second end of the water stopping lifting lever is provided with a blocking block 75 and corresponds to the second pressure relief hole 63, the water stopping lifting lever 74 can be driven to swing by the ascending or descending movement of the water inlet floating barrel 72, and then the blocking block 75 is controlled to block or separate from the second pressure relief hole 63. Namely, when the water inlet floating barrel 72 rises, the water stopping lifting lever 74 is driven to swing, so that the blocking block 75 is controlled to block the second pressure relief hole 63, and when the water inlet floating barrel 72 falls, the water stopping lifting lever 74 is driven to swing, so that the blocking block 75 is controlled to be separated from the second pressure relief hole 63.

So set up, when the water in the water tank begins to discharge, the initial stage, even there is the decline in the water level in the water tank, nevertheless as long as can provide sufficient buoyancy for little keg float 73 with shutoff bottom outlet 712, the water level in the water storage chamber 711 just can not change, the position of intaking keg float 72 also can not change, also be the second pressure release hole 63 remains the state of being shutoff throughout, so, can let the water in the inlet channel 801 discharge from helping flush water passageway 802, and the power of dashing is bigger. When the water level drops to a level that cannot provide enough buoyancy for the small floating bucket 73, the small floating bucket 73 opens the bottom drain hole 712, water in the water storage cavity 711 starts to be discharged, the water level becomes low, and the position of the water inlet floating bucket 72 also starts to drop, so that the water stop lifting lever 74 is driven to swing, the blocking block 75 is controlled to be separated from the second pressure relief hole 63, and finally the hydraulic drain valve 60 is opened to realize water supplement.

Specifically, the bucket body 71 may be provided with a penetration hole, the diameter of which is smaller than that of the bottom drain hole 712, and when the water level decreases (rapidly decreases in a short time), the amount of water seeped from the penetration hole by the water in the water storage chamber 711 is small and can be ignored; when water is stored, the water can enter the water storage chamber 711 through the penetration hole, so that the problem that the bottom drainage hole 712 is blocked by the small floating barrel 73 and cannot enter the water storage chamber 711 when the water level rises is solved. Of course, in other embodiments, this is not limiting.

Of course, in other embodiments, the structure of the tank inlet valve 60 is not limited thereto, and the structure for achieving the delayed opening of the tank inlet valve 60 is not limited to the structure of the float assembly 70 described above as long as the delay assembly for allowing the delayed opening of the tank inlet valve 60 can be achieved.

Furthermore, in this embodiment, two air-replenishing holes 81 are formed in the top of the water inlet main body 80, the two air-replenishing holes 81 are respectively communicated with the water tank water inlet channel 803 and the water-flushing assisting channel 802, the water tank water inlet channel 803 and the water-flushing assisting channel 802 are both provided with anti-siphon covers 82 corresponding to the air-replenishing holes 81, when water flows through the water tank water inlet channel 803 or the water-flushing assisting channel 802, the water flow impacts the corresponding anti-siphon covers 82 upwards, so that the anti-siphon covers 82 block the air-replenishing holes 81 to realize circulation; when the water tank inlet channel 803 or the flushing assisting channel 802 cuts off water, the anti-siphon cover 82 falls down to open the air supply hole 81, so that a good anti-siphon effect is achieved.
