A dispensing system comprises a first electronic sensor and a controller. The first electronic sensor may be configured to detect a first change from a first amount of a fluid product in a dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir. The controller may be coupled to the first electronic sensor and configured to receive a first signal from the first electronic sensor indicative of the first change. The dispensing system reservoir may be disposed in the dispensing system. A method for determining a remaining service interval for a dispensing system reservoir is also provided.

A system and method is provided for monitoring hygiene compliance.

A lavatory system includes a basin having a water collecting area having a back wall, a bottom wall, and a front wall. The back wall of the water collecting area is proximate the wall on which the lavatory system is mounted. Further, an opening may extend through the front wall. The lavatory system also includes a hand dryer having a blower located below the water collecting area and a first plenum having an input and an output. The input is connected to the blower to receive a first air flow from the blower, and the output is aligned with the opening in the front wall of the water collecting area to deliver the first air flow from the front wall over the water collecting area.

A liquid soap filling device is provided. The liquid soap filling device includes a body member having an upper portion and lower portion. The upper portion includes an inner volume accessible through an opening in a top surface of the upper portion. The inner volume receives a measured amount of liquid soap through the opening. The lower portion includes a frustoconical shaped inner volume and a valve system, wherein the valve system controls the dispensing of the liquid soap from within the inner volume of the upper portion through the frustoconical shaped inner volume of the lower portion and through a fill port of the lower portion and into an under-counter dispenser container.

A faucet structure and method for assembling same is disclosed. The structure includes an outer tube, flow guiding part and cap. The outer tube is provided with an assembling gap. The flow guiding part is provided within the outer tube, and with half shells. The first half shell is provided with supplying manifold passage(s) corresponded to the assembling gap, and a first assembling ramp facing the second half shell. The second half shell is provided with a second assembling ramp facing the first half shell and inclined oppositely to the first assembling ramp, and a first threaded connection portion facing one end opening of outer tube. The cap is in correspondence with the end opening, and provided with a second threaded connection portion corresponded to the first threaded connection portion. These threaded connection portions are engaged by threaded connection, while those half shells are pressed against a tube wall.

A counter mount fluid dispenser has a spout having an opening for dispensing a fluid. The connection shaft extends downwardly from the spout. A swivel base is mounted to the connection shaft. The swivel base swivels relative to the connection shaft. The swivel base includes a mounting shaft having a mounting shaft nut that is configured with the spout to engage a countertop by clamping force. The mounting shaft nut has a mounting shaft nut lower extension. A mounting shaft nut external thread is formed on an external surface of the mounting shaft nut lower extension. A mounting shaft nut retainer is threaded to the mounting shaft nut lower extension.

A base including a bottom plate is configured for mounting to a surface, and a top plate. One or more dispensing bottles including flanged bottoms. The base top plate has one or more openings for the one or more dispensing bottles. The flanged bottoms have a diameter greater than the one or more openings of the base top plate, and the one or more openings has a releasable portion and a non-releasable portion. The releasable portion accommodates the one or more flanged bottoms to slide between the base bottom plate and the base top plate. A locking mechanism has a holding pin and a tumbler. The tumbler is accessible external to the base plate by a key to lock the one or more dispensing bottles into the base plate by rotating the tumbler to hold the releasable portion.

An exemplary tabletop foam sanitizer dispenser includes a reservoir for containing liquid sanitizer. The bottle has a base for sitting on a surface. The base has a base diameter. The bottle has a top and a neck located proximate the top having an opening. The opening has an inner neck diameter. The base diameter is at least 3 times the inner neck diameter. A pump assembly is also included. The pump assembly has a cylindrical housing. The cylindrical housing having an outer housing diameter. The outer housing diameter is less than the inner neck diameter. The cylindrical housing is inserted into the bottle through the neck opening. A pump is located in the cylindrical housing. The pump includes a liquid inlet, an air inlet, a liquid outlet and an air outlet. A pump is motor located in the cylindrical housing. A battery is also located in the cylindrical housing. A nozzle housing is located above the cylindrical housing. A liquid and air mixing chamber located in the outlet nozzle housing. The liquid and air mixing chamber is in fluid communication with the liquid outlet and the air outlet. An outlet nozzle is in fluid communication with the mixing chamber and is located in a lower portion of the nozzle housing. The table top dispenser further includes a sensor for detecting a hand of a user positioned below the nozzle.

A fluid dispenser, such as a skincare product dispenser, comprises a dispenser housing configured to hold a reservoir of fluid for dispensing and a drive assembly for interacting with the reservoir and causing dispensing of the fluid. A fluid detection sensor is positioned within the dispenser housing proximate the reservoir and configured to detect a capacitance level therein. A controller is configured to determine, based on data from the fluid detection sensor, a change in the fluid level across a dispense. The controller is also configured to determine, based on the determined change, that the fluid level in the reservoir reaches a threshold level and cause an action, such as providing an alert, sending information to a remote server, or modifying an operating parameter.
