Abstract: The present utility model relates to the field of manufacture of sanitary wares, and provides a toilet. The toilet includes a seat body with a sewage accommodating bowl, and a cistern. The inside of the cistern is provided with a fill valve, a first ring flushing pipeline, a first water inlet end of the first ring flushing pipeline is selectively in fluid communication with the fill valve, a first water outlet end of the first ring flushing pipeline is in fluid communication with a ring flushing port opening, and the first ring flushing pipeline includes a first jet flow increasing structure; a second bottom flushing pipeline, a second water inlet end of the second bottom flushing pipeline is selectively in fluid communication with the fill valve, and the second bottom flushing pipeline includes a second jet flow increasing structure; and a pipeline switching mechanism, being able to automatically switch the fluid communication between the first ring flushing pipeline and the fill valve or between the second bottom flushing pipeline and the fill valve in response to a water level in the cistern. By using such toilet, the sewage accommodating bowl can be more cleanly and thoroughly flushed with the same water consumption, or a low-profile cistern design can be realized under the same water pressure requirement.

Abstract: The present utility model relates to a toilet. The toilet comprises: a seat body having a sewage accommodating bowl; a ring flushing pipeline, the ring flushing pipeline being used for performing ring flushing on the sewage accommodating bowl; a bottom flushing pipeline, the bottom flushing pipeline being used for performing bottom flushing on the sewage accommodating bowl; and a flush valve, the flush valve being capable of being in fluid communication with at least one of the ring flushing pipeline and the bottom flushing pipeline, such that water for flushing flows to the sewage accommodating bowl via the flush valve. A first power supply apparatus is arranged in the seat body, and the first power supply apparatus is configured to supply power to the flush valve. By “sinking” the power supply apparatus which supplies power to the flush valve to the seat body of the toilet, the flexibility of supplying power to the flush valve and the flexibility of the arrangement of the power supply apparatus are achieved, thereby avoiding problems such as a layout difficulty or an electrical safety issue caused by concentrating electronic devices on a toilet lid or other positions.

Abstract: The present utility model provides a magnetic suspension drain, comprising a first connecting member and a second connecting member that are connected with each other and adapted to respective connection to a drain opening of a drain device and a drain pipe. The magnetic suspension drain further comprises a magnetic suspension inner core arranged in the first connecting member, and the magnetic suspension inner core comprises a rotary floating rod and a rotary sealing cover. The rotary floating rod is provided with a first magnet, and a repulsive second magnet is provided inside the first connecting member. The magnetic suspension inner core is configured as follows: in a sealed state, the rotary floating rod drives the rotary sealing cover to maintain sealing with a drain end of the first connecting member under the action of a repulsive force of the first magnet and the second magnet; and in a draining state, the rotary sealing cover is disengaged from the sealing with the drain end of the first connecting member under the action of water pressure and rotates along with the water flow to promote drainage. The present utility model provides a magnetic suspension inner core that utilizes magnetism to realize automatic sealing and drainage, and rotates along with the water flow during drainage to promote drainage through the rotary floating rod and the rotary sealing cover that are integrated into one whole piece.
