A microcontroller is electrically connected to the sensor and may receive and process the ToF measurement using an algorithm to determine a bowl status. The toilet also includes at least one water valve that is disposed between the bowl and the water source, and that is electrically connected to the microcontroller for instructing the at least one water valve to move from a first position to a second position for a duration of time, wherein the duration of time corresponds to the bowl status.

Disclosed in the present utility model is a connecting rod drive mechanism for a water discharge valve, comprising a base, a first stage connecting rod, and a last stage connecting rod, the first stage connecting rod and the last stage connecting rod are movably arranged on the base, a drive part, a turning part, and a transmission part are provided on the last stage connecting rod, the drive part cooperates in transmission with an initiation assembly of the water discharge valve, the transmission part cooperates in transmission with the first stage connecting rod, the turning part forms a relative turning connection with the base, the turning part is located between the drive part and the transmission part, or the transmission part is located between the drive part and the turning part, and the first stage connecting rod is driven so as to impel the last stage connecting rod, causing a drive part of the last stage connecting rod to drive the initiation assembly of the water discharge valve to be opened and discharge water. The connecting rod drive mechanism of the present utility model is able to amplify drive travel, can allow for more flexible positioning of a drive mechanism, and there is relatively low eccentric force during the process of driving, which is beneficial for extending assembly life.

A touchless actuation system for a toilet includes a touchless sensor, a motor assembly, and a processing circuit. The touchless sensor is located within a closed reservoir of the toilet. The processing circuit is configured to receive a signal from the touchless sensor and to detect an object within a detection region based on the signal. The detection region is external to the closed reservoir. The processing circuit is configured to facilitate flushing of the toilet through interaction with the motor assembly when the object is detected.

A touchless siphon valve assembly for a toilet assembly having a toilet tank, the touchless siphon valve assembly comprising a control assembly and a siphon valve assembly, wherein the control assembly comprises a capacitive sensor, a controller, and a power source, and the siphon valve assembly comprises a tubular core, a head coupled to and surrounding an upper end of the tubular core, a spray initiator positioned in the head and extending into the tubular core, and a solenoid valve fluidly coupled to the spray initiator, the capacitive sensor is configured to detect a user gesture, and to indicate detection of the first gesture to the controller to initiate a flush cycle.

The embodiments disclosed herein are directed towards vacuum-assisted toilet systems and methods of using the vacuum-assisted toilet systems. An example vacuum-assisted toilet system includes a toilet bowl defining an outlet and a flush valve fluidly coupled to the outlet. The vacuum-assisted toilet system also includes at least one water source fluidly coupled to the toilet bowl. The water source is configured to supply water to the toilet bowl. The vacuum-assisted toilet system also includes at least one water actuator coupled to the water source. The water actuator is configured to control the amount of water that is supplied by the water source to the toilet bowl. The vacuum-assisted toilet system also includes a controller that is configured to at least partially control the operation of one or more components of the vacuum-assisted toilet system, such as at least one of the flush valve or the water actuator.

According to an embodiment, a toilet device includes a detector configured to detect at least one of a water level inside a flush toilet or an indicator associated with the water level, a clog determiner determining a clog state of the flush toilet based on a detection result of the detector, and a controller determining, based on a determination result of the clog determiner, whether or not to prohibit a flushing water supply to the flush toilet. The controller sets a flush prohibition time at least after the flushing water supply to the flush toilet has ended. A flush operation for flushing the flush toilet not is accepted temporarily in the flush prohibition time. The clog determiner determines the clog state of the flush toilet based on the detection result of the detector within the flush prohibition time or directly after the flush prohibition time.
