A toilet assembly may comprise a toilet tank to hold flush water, a flush valve assembly positioned in the toilet tank, a toilet deck, a toilet bowl, a trapway in flow communication with the toilet bowl, a container positioned in the toilet tank, and a connecting tube extending from an interior of the container to the trapway. A first gasket positioned between the toilet tank and the toilet deck may form a seal around the flush valve assembly. A second gasket positioned between the toilet tank and the toilet deck may form a seal around the connecting tube. The first gasket may comprise a recess for receiving the flush valve assembly and a protrusion extending into the toilet deck.

The embodiments of this application disclose a control system and a control method of intelligent toilets. The control system includes a toilet body, a communication device which is set on the toilet body to acquire the geographic location information of the toilet body, and transmit the acquired geographic location information to a server which acquires the external environment information of the toilet body based on the geographic location information and generates the adjustment parameters based on the external environment information. The external environment information includes the environment temperature information, the environment humidity information, and the sensory temperature information. The control system also includes a controller which is set on the toilet body to receive the adjustment parameters from the server and control the working temperature of the toilet body based on the adjustment parameters.
