Technical Field

[0001] The invention relates to the technical field of bathroom equipment, and in particular to a multi-stage flushing water tankless toilet and a flushing method thereof. Background Art

[0002] Existing toilets generally have water tanks with water storage functions, and adopt a flushing mode of flushing down with water stored in the water tank. The rear of this traditional toilet requires a larger and higher installation space; most existing manufacturers use one-piece molding and split molding methods to achieve the flushing function of the toilet. This method takes up a large space and is a major obstacle to the increasingly popular smart toilets. It cannot meet the placement of functional components inside the smart toilet cover; the smart toilet cover usually requires a cleaning part, a heating part, an electronic control part and a filtering function. If tap water is used directly to inlet water, the flushing function of the toilet cannot be guaranteed.

[0004] The tankless smart toilet as described above adopts a tankless siphon flushing method, which solves the problem that traditional toilets require a larger and higher installation space. Flushing from top to bottom will not flow back. However, when flushing the above toilet, it is only a water flushing process, and it may not be able to be thoroughly flushed.
