A capsule includes an upper body portion and a lower body portion that is coupled to the upper body portion. The lower body portion includes a lower wall that defines a lower opening. The lower body portion and the upper body portion together define an internal cavity. At least one of the upper body portion or the lower body portion includes a plurality of grooves spaced at intervals along a circumferential direction with respect to a central axis of the capsule. The plurality of grooves extends at an angle in a partially axial direction and a partially circumferential direction.

The present invention relates to a system for dissolving at least one detergent tablet or detergent granulate in water and thereby creating a detergent liquid, said system comprising a chamber (103) for dissolving said tablets or granulate, wherein said chamber comprises an opening (105) for receiving said detergent tablet and said water and a detergent liquid outlet (135, 137). The chamber further comprises an inner colander (125) for positioning said at least one tablet or detergent granulate. Thereby, a very efficient dissolving process can be performed, and a uniform detergent liquid is obtained. By positioning the tablets or granulate inside the colander, it is ensured that all sides of the tablet are in contact with the liquid in the chamber.

A valvular conduit, preferably a Tesla valvular conduit, in which a plug member is coaxially received within a bore in a sleeve member and in which passageways are defined between the plug member and the sleeve member within interior walls configured to permit mixing of fluid flowing through the passageways in at least one direction, preferably, the relatively free passage of fluid through the passageways upstream but increased the resistance to downstream flow of the fluid through each passageway.

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

A chemistry dispensing assembly for a laundry appliance includes a reservoir that dispenses a laundry chemistry to a treatment chamber. A mixing channel is positioned below the reservoir that receives the laundry chemistry dispensed from the reservoir. A fluid assembly delivers a fluid carrier through a flow path that includes the mixing channel. The mixing channel is defined between an underside of the reservoir and an upper surface of the mixing channel.

An apparatus for generating a powerful oxidative hydrogen peroxide foam and chemically stable application process comprises separate supply lines for respectively conveying liquid hydrogen peroxide and liquid foaming agent from separate storage receptacles, a mixer for mixing the liquid hydrogen peroxide and foaming agent once combined together, an air supply line for aerating the foamable liquid hydrogen peroxide mixture, and a foam generating device for mechanically agitating the aerated foamable liquid hydrogen peroxide mixture to form the hydrogen peroxide foam for subsequent discharge to a substrate. There is also disclosed a related method for generating the hydrogen peroxide foam.

A washing powder feeding device includes a frame, a water pipe, a powder feeding mechanism and a vortex tube body respectively assembled on the frame. The vortex tube body is defined with a first cylindrical cavity, an intermediate truncated cone cavity and a second cylindrical cavity from top to bottom, the first cylindrical cavity has a larger diameter than the second cylindrical cavity, a water inlet is formed on a side wall of the vortex tube body and communicated with and tangent to the first cylindrical cavity, the water pipe is communicated with the water inlet, and the powder feeding mechanism is configured to feed washing powder into the first cylindrical cavity. The device can effectively prevent the dissolved washing powder from adhering onto the pipeline to cause clogging of the pipeline, thereby ensuring the washing reliability.

By positioning the tablets or granulate inside the colander, it is ensured that all sides of the tablet are in contact with the liquid in the chamber.

An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

An exemplary foam-at-a-distance soap or sanitizer dispenser includes a housing, a container for holding a foamable liquid, and a pump in fluid communication with the container. The pump has a pump chamber air inlet, a pump chamber air inlet valve, a pump chamber air outlet, a pump chamber air outlet valve, a pump chamber liquid inlet, a liquid chamber liquid inlet valve, a pump chamber liquid outlet, and a pump chamber liquid outlet valve. The exemplary dispenser further includes an air conduit extending from the pump chamber air outlet to a remote mixing chamber and a liquid conduit extending from the pump chamber liquid outlet to the remote mixing chamber. The remote mixing chamber is located at a distance from the pump chamber air outlet valve and the pump chamber liquid outlet valve and that distance is greater than about 3 inches. A one-way liquid check valve is located proximate the mixing chamber, one or more mix media located downstream of the mixing chamber and an outlet nozzle located proximate the mixing chamber.
