The toilet water tank mainly includes a tank body and a water inlet valve assembly and a flush valve assembly installed in the tank body. External tap water is input into the tank body through the water inlet valve assembly. After reaching a predetermined liquid level, the water inlet valve assembly automatically closes. When flushing, open the flush valve assembly to quickly drain water. The existing intelligent toilet flushing control method usually draws water through a pump, and then realizes the vortex flushing and direct flushing of the toilet through a water circuit switching device. If you apply for No. 2023117327626 discloses a water path switching device for an intelligent toilet, which includes a cavity and a float, wherein the cavity is provided with a water inlet, an upper water outlet and a lower water outlet, the float can be movably arranged between the water inlet, the upper water outlet and the lower water outlet, and when the float is located at the lower water outlet, a constant flow channel is provided between the float and the lower water outlet; when used, the flushing time is controlled by controlling the working time of the pump, thereby controlling the amount of water for flushing.

[0003] When the above-mentioned smart toilet is working, the pump is started by the sensor, the pump supplies water to the water inlet, and the water supply time of the pump body is controlled to make the upper water outlet and the lower water outlet connected at the same time, and then the lower water outlet is flushed again, and finally the upper water outlet and the lower water outlet are connected again for water sealing treatment; during the whole process, the pump body needs to work in three stages, and the three-stage work is more power-consuming, and there will be noise when the pump body is started, and the flushing sound is loud. At the same time, if the upper water outlet and the lower water outlet discharge water to seal at the same time, it will cause more water consumption for water seal, resulting in Waste of water resources; or first connect the upper water outlet with the lower water outlet at the same time, then seal the upper water outlet and fall back, start the pump again to make the upper water outlet and the lower water outlet discharge water at the same time for water sealing. During the whole process, although the pump adopts two-stage operation, it is more power-saving and has less noise, but during the flushing process, vortex flushing and direct flushing are carried out at the same time. The impact force of the vortex flushing and the impact force of the direct flushing will partially buffer each other, making the flushing pressure smaller, the flushing is not clean, and the problem of large water consumption for water sealing still occurs.

Specifically, a supplementary water outlet pipe 221 is convexly provided on the outer side wall of the water outlet pipe 22, and a supplementary water outlet channel connected to the water outlet pipe body and leading to the outside of the supplementary water outlet pipe 221 is provided on the supplementary water outlet pipe 221, and the open mouth of the supplementary water outlet channel is the above-mentioned shunt outlet, and the supplementary water outlet pipe 221 is located above the buoy 23, and a supplementary water inlet pipe 431 is convexly provided on the bottom surface of the straight-wash water outlet pipe 43, and a supplementary water inlet pipe 431 is provided on the supplementary water inlet pipe 431. A supplementary water outlet channel connected to the straight-wash water outlet pipe and leading to the outside of the supplementary water inlet pipe 431 is opened, and the open mouth of the supplementary water inlet channel is the above-mentioned shunt inlet, and the above-mentioned The connecting pipe connects the outlet pipe body and the flushing outlet pipe together, and a backflow prevention block for blocking the lower end of the side opening is convexly provided on the side convex block within the lower end range of the side opening 200; when in use, after the flushing water outlet and vortex flushing are performed, water re-enters the box body, and the water level in the box body 1 rises synchronously with the water level in the outlet pipe 22. When the water level in the outlet pipe 22 rises to the diversion outlet, water overflows from the outlet pipe 22 into the connecting pipe and enters the flushing outlet pipe 43 from the diversion inlet. The water in the flushing outlet pipe 43 then flows out through the flushing pipeline, and the ceramic water cover is water-sealed; furthermore, the setting of the backflow prevention block ensures that when water enters the flushing outlet pipe 43 from the connecting pipe and the supplementary water inlet pipe 431, it will not flow into the valve seat 41, and can directly flow out from the flushing outlet pipe 43 to water-seale the ceramic water cover.

[0031] The utility model is a smart toilet water tank. When it is used, water enters the box body 1 through the water inlet valve assembly 2, and the float box 45 gradually floats along the water inlet pipe body 44. When the water in the box body 1 reaches the high water level, the float box 45 drives the valve stem 462 to move upward at the same time, and the front end of the lower inclined rod 52 is driven upward accordingly, and the lower end of the upper inclined rod 51 is driven to move forward, and the valve plate 461 flips downward, and the valve plate 461 blocks the second water outlet. The pump body 3 is started by induction. After the pump body 3 is started for several seconds, the water in the box body 1 enters from the water inlet pipe body 44, and the water enters the vortex outlet pipe 42, and then rushes to the surface of the ceramic toilet from the vortex flushing pipeline at high speed and forms a vortex shape, thereby realizing vortex flushing of the toilet; during the vortex flushing process, the water level in the box body 1 drops, the float box 45 drops accordingly, and the valve stem 462 drives the lower tilt rod 52 to move downward, and the valve plate 461 flips upward, and the valve plate blocks the first water outlet. At this time, the pump body 3 is started again for several seconds, and the remaining water in the box body 1 enters the direct flushing water outlet pipe 43 and flushes out from the direct flushing pipeline, thereby realizing the direct flushing of the toilet and the flushing is completed; the water level in the box body 1 drops to a low level, and the water inlet valve assembly restarts to inlet water. The water level in the box body 1 gradually rises, and the water in the box body 1 will also flow into the water outlet pipe 22. The water in the water outlet pipe 22 will rise synchronously with the water level of the box body 1. When the water level in the water outlet pipe 22 reaches the diversion outlet, the water in the water outlet pipe 22 will flow out from the diversion outlet, and then through the connecting pipe to the diversion inlet of the direct flushing water outlet pipe 43, so that water flows out of the direct flushing water outlet pipe 43 again for water sealing treatment. Compared with the prior art, the invention adopts a two-stage water outlet with vortex flushing and direct flushing separately. The first stage of flushing is vortex flushing of the inner surface of the toilet, and the second stage of flushing is direct flushing. The vortex flushing and the direct flushing are independently performed without affecting each other, so that the pressure during flushing is relatively high and the flushing is relatively clean; moreover, after the flushing is completed, the water overflowing in the water outlet pipe 22 is transported to the direct flushing water outlet pipe through the connecting pipe to seal the ceramic water cover, and there is no need to start the pump body for water sealing again. The water sealing process is more energy-saving and the pump body generates noise for a shorter time; at the same time, by using a connecting pipe for water sealing, a large amount of water will not be flushed out at the same time as the water sealing, less water is lost during the water sealing process, and the water consumption is less, thereby saving water resources.

[0032] The product form of the utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the utility model.
