A an analytical toilet comprising a bowl for receiving excreta comprising a platform for receiving feces; a urine drain; a feces outlet from the bowl; and a urine outlet from the bowl; wherein the platform and drain are separated by a raised hump; at least one first load cell for detecting the weight of the bowl; at least one fecal sensor for detecting at least one property of the feces; and at least one urine sensor for detecting at least one property of the urine is disclosed.

An excrement determination method includes: acquiring sensing data detected by a first gas sensor; acquiring image data captured by a camera; making a first determination of determining whether a gas concentration indicated by the sensing data is higher than a first reference concentration; making a second determination of executing image processing onto the image data and determining whether the image data contains an image about defecation; making a third determination of determining, based on a determination result of the first determination and a determination result of the second determination, that at least one of the defecation and flatulating occurred; and outputting a determination result of the third determination.

An output device includes: an acquisition part that acquires a first image covering excrement captured by a camera to photograph an inside of a bowl of a toilet; a dividing part that divides the acquired first image into a plurality of divisional areas; a calculation part that calculates an area representative value including a representative value of each of the color components of each of the divisional areas; and an output part that outputs the calculated area representative value.

A leak and/or overflow detection system for an aircraft may comprise a first sensor configured to be disposed in a toilet bowl, a second sensor configured to be disposed in a waste tank, a first acoustic emission sensor and a second acoustic emission sensor configured to be disposed upstream and downstream of a valve, or any combination of the first sensor, the second sensor, and the acoustic emission sensors. A controller may receive various data from the sensors and determine whether a leak and/or an overflow condition is occurring or about to occur.

A smart toilet (100) includes an information acquisition device (110) and a control device (120). The information acquisition device (110) is configured to acquire feature information of the smart toilet (100) in a working state, the feature information at least including voiceprint information and odor information, or voiceprint information, or odor information of a human body using the smart toilet (100). The control device (120) includes an identity recognition component (121) configured to recognize, according to the feature information, the identity of the human body using the smart toilet (100). An electric appliance system including the smart toilet (100) is further included.

A management system includes: a detection device including a main body that has a shape installable to a discharge port, electrodes that are provided in the main body and are detectors detecting a liquid, and a communication device that functions as a transmitter transmitting information regarding a detection result obtained by the detector; and an estimation device including a receiver that receives the information transmitted from the transmitter, and an estimator that estimates a discharge state of the liquid from the discharge port based on the information received by the receiver.

Provided is a mobile toilet that can be used well.

A mobile toilet includes a trailer, a toilet bowl disposed in a cargo box of the trailer, a drain tank disposed in the cargo box and storing sewage discharged from the toilet bowl, a drain passage communicating between the toilet bowl and the drain tank, and a second conveyance device provided in the middle of the drain passage. The toilet bowl has a drain trap communicating with an upstream end of the drain passage, and the drain passage passes a position higher than a sealing water level of the drain trap, and has a spout space provided in a position higher than the sealing water level of the drain trap.

A flush assembly for a plumbing fixture, the assembly comprising a sprayer body, wherein the sprayer body comprises a bottom wall, a front wall, and a rear wall, the sprayer body is configured to be in fluid communication with a water source, and the sprayer body bottom wall comprises a first outlet through which flush water is delivered during a flush cycle. The first outlet may comprise a slot shape and/or an arc slot shape. The flush assembly provides a large flush profile.

The present invention provides a device for collecting liquid and a smart toilet comprising the same. The device comprises a fixing support, a swinging mechanism, a suction tube assembly and a pump body mechanism; the suction tube assembly (9) comprises a slide rail component and a retractable suction tube component disposed therein, one end of the slide rail component is connected to the swinging mechanism; the suction tube component comprises a suction tube internally provided with a cavity and an opening disposed above the cavity, and a first conduit disposed in the suction tube one end of the first conduit is inserted in the cavity, the other end of the first conduit is connected to the pump body mechanism. The fixing support is fixedly connected to the toilet body; the suction tube component swings towards the center of the toilet under the effect of the swinging mechanism, the suction tube component is used for receiving the urine. The device further comprises a liquid-level sensing mechanism for monitoring the amount of the urine in the cavity in real time and controlling the start and stop of the pump body mechanism according to the amount of the urine. The device takes the urine sucked in the air as a sample for health analysis, avoiding the problem of cross-contamination caused by sucking the urine from the inside surface of the toilet.

An analytical toilet comprising a bowl adapted to receive excreta; one or more conduits for transporting a sample from the bowl; one or more fluid sources in fluid connection with the one or more conduits; and one or more microfluidic chips, comprising at least one fluid inlet; at least one fluid outlet; and a sensor configured to detect at least one property of an excreta sample is disclosed.
