A showerhead includes a flow device and a flow distribution member. The flow device is configured to produce a substantially laminar fluid stream. The flow distribution member is coupled to the flow device and is spaced apart from the flow device. The flow distribution member is configured to receive the substantially laminar fluid stream from the flow device and to produce a distributed fluid flow.

The disclosure relates to a nozzle for a device for the dermo-cosmetic treatment of dark skin spots by cyto-selective cryotherapy comprising a spray jet supplied by a tank of pressurised liquified cryogenic gas. The nozzle comprises an upper ring for connecting to a shell, extended by a central body of which the side wall which narrows downwards has longitudinal openings and delimits a gas expansion chamber communicating with a frustoconical dispersal conduit arranged inside an end piece to be applied to the skin and opening to the outside through a discharge port.

A micro-bubble spray head and a washing apparatus. The micro-bubble spray head includes an integrated spray tube and a micro-bubble bubbler fixed on the outlet end of the integrated spray tube; a throttling passage portion is formed in the integrated spray tube; a plurality of throttling passages parallel to each other and having a uniform cross section are formed in the throttling passage portion along a water stream direction, so that a plurality of water streams can be formed in the plurality of throttling passages parallel to each other and having the uniform cross section and are sprayed out from the outlets of the plurality of throttling passages parallel to each other and having the uniform cross section in an expansion manner, so as to form negative pressure near the outlets; a plurality of air inlets serving as air inlet passages are further provided on the integrated spray tube.

The present invention discloses a light-emitting water outlet structure, and relates to the technical field of bathroom accessories. The light-emitting water outlet structure provided by the present invention can stabilize the water flow, so that the water outflow is mild and stable; the emitted light is totally reflected in the water flow, so that the emitted light flows with the water flow, thus the length of the propagation path of the light in the water flow is increased, and a better visual effect is achieved.

A fluid cleaning device includes a spheroid-shaped member defining an internal void. The spheroid-shaped member further includes a wall defining a plurality of apertures and at least partially surrounding the internal void and an inlet orifice that receives a cleaning fluid under pressure. A tubular nozzle projects from the inlet orifice and into the internal void to mitigate fluctuation of one of the internal pressure and flow velocity of the cleaning fluid within the spheroid-shaped member.

A method and apparatus for generating a wave in a body of water may include altering a flow of water as it is urged through an inlet, contoured passage, and outlet. For example, a primary flow of water may be altered so that one or more secondary flows are created at angles to the direction of primary flow.

A fine particle sprayer including a nozzle for dispersing a liquid disinfectant into a spray plume of droplets and a means for directing pressurized air below the spray plume to increase droplet transfer efficiency, and above and around the spray plume to prevent errant droplets from drifting toward an operator. A sprayer system includes a sprayer, a housing, and a blower that may be removably attached to the sprayer for generating an air stream below the droplets to improve droplet transfer efficiency.

The invention relates to a dispenser 20 for the spray delivery of a preparation 18. The dispenser comprises: a reservoir 22 suitable for containing the preparation 18, a mechanical pump 24, a load chamber 26, a nozzle 28 having a delivery axis, and a delivery cone 30 having an axis. The mechanical pump is able, whenever operated: to take a predetermined amount of preparation from the reservoir, to supply said amount of preparation to the load chamber upstream of the nozzle, and to create a delivery pressure in the load chamber. The nozzle is able to deliver said amount of preparation in the form of an aerosol spray 180. The dispenser according to the invention is characterized in that the delivery cone comprises, in the proximity of the nozzle, at least one through-hole 320 suitable for putting the inside of the delivery cone into communication with the surrounding environment.

A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.

A device for controlling the shape of discharged liquid comprises a liquid inlet end and a liquid outlet end. A passage allowing liquid to flow therein is disposed between the liquid inlet end and the liquid outlet end. The liquid outlet end comprises a liquid outlet in a rotationally symmetric shape. The liquid inlet end comprises a liquid inlet formed in one end of the passage. A liquid outlet channel is disposed between the liquid outlet and the other end of the passage and communicated with the passage. Cross-sections of different positions of the liquid outlet channel in a liquid outlet direction are of a rotationally symmetric shape corresponding to the shape of the liquid outlet. Through the liquid outlet in a rotationally symmetric shape and the corresponding liquid outlet channel, a discharged liquid column has a special shape under the acting force of liquid molecules in air.
