Dispensing head (1) intended to be fitted on a container that contains at least one product to be dispensed, this dispensing head comprising: a body (3), an engaging part (10), in particular a core (10), that defines with the body (3), at rest, a dispensing orifice (12) having an annular section.

A dishwasher includes a tub defining a washing space, a sump disposed below the tub and configured to store washing water received from the tub, a pump configured to supply the washing water from the sump to the washing space, and a spray arm configured to discharge the washing water from the pump into the washing space. A channel defined inside the spray arm is configured to spray the washing water or the washing water including microbubbles into the washing space.

Disclosed is a concealed flow regulator, which comprises a housing portion and a diversion device, the housing portion is disposed with a mutation cavity and a suction passage, the diversion device is used to divide the water flowing, the divided water enters the mutation cavity and negative pressure generates; the external revolution surface of the housing portion is disposed with external thread, the housing portion is threaded to the water supplying opening via the external thread; the suction passage has an internal port faced to the mutation cavity and an external port at the external revolution surface, the air flowing clearance is connected to the external port, so that air can enter the mutation cavity through the air flowing clearance, the external port and the internal port. It has advantages: the flow regulator can be assembled in the water supplying opening and be concealed.

A spray system for dust control on a shearer machine that operates laterally with respect to a mining floor surface is provided where the spray system is provided with a set of first ranging arm sprays mounted on a first ranging arm and wherein said first ranging arm is located on a first end of a shearer machine chassis. A set of second ranging arm sprays is optionally provided and is mounted on the upper side of the first ranging arm and resides approximate to and in operational relationship to the set of first ranging arm sprays. Furthermore, a plurality of chassis spray sets may also be optionally provided and are located on a mining side of said shearer machine chassis and reside in a non-linear format. Moreover, a set of shearer-clearer venturi arm sprays may also optionally be provided and is mounted on a shearer-clearer venturi arm that resides as an angular extension of the set of first shearer-clearer arm sprays.

A system is proposed for cleaning and sterilization wherein a carrier fluid is provided through a spray head having a mixing chamber, the flow of carrier fluid converted to a spray by the spray head. In the mixing chamber, ozone and ozone reaction products are mixed with the flow of carrier fluid to obtain a higher mixture of ozone and ozone reaction products in the carrier fluid immediately before the carrier fluid and ozone and ozone reaction products are dispensed as a spray.

Various methods and apparatuses may be used to spray sloped surfaces, such as by using a nozzle (1). The method of the invention for spraying a fluid on turf having sloped surfaces may include spraying the fluid using a flat fan spray angle between 110 and 130 degrees and an inclination angle between 4.5 and 9.0 degrees. In some implementations, spraying the fluid may include spraying the fluid using a flat fan spray angle of approximately 120 or 127 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 4.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 6.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 9.0 degrees. In some implementations, the inclination angle may include a backward facing angle. In some implementations, the orifice of the nozzle (1) is formed by the interaction of a bent vee slot cut (10) though a hemispherically terminated hole creating a truncated elliptical orifice hole.

A sanitary fixture is provided having an upstream end and a downstream end, the sanitary fixture includes a mounting housing having a thread which is matingly engagable with a thread provided on a water outlet of a sanitary outlet fitting. The mounting housing has a downstream housing end side with flow-through holes. At least one insertion part can be inserted into the mounting housing as far as an insertion stop. The fixture includes an aerated jet regulator which is configured such that a circumferential wall of the mounting housing includes at least one aeration duct at least in a subregion of at least a double-walled configuration. The at least one aeration duct, which is arranged towards the downstream housing end side, opens out in at least one aeration opening leading into a housing interior of the mounting housing.

A shower head assembly with air holes may include a connector, a mixing unit, an adapter unit and a shower head. Since the diameter of the through hole is larger than the first connecting hole, the air holes can be covered to prevent the air holes from being exposed outside of the shower head assembly. Thus, it not only improves the appearance of the shower head, but also prevents the air holes from blocking by dust or other stuff. Also, with the design of the connector, the mixing unit combining the adapter unit, the shower head assembly of the present invention can apply in both the fixed shower head and the handheld shower head to improve the application of the shower head assembly.

In this shower apparatus, a part of an internal space thereof closer to the outer circumference thereof than an aeration unit is defined as a plurality of small spaces, and all of the small spaces have a uniform channel resistance.

In this shower apparatus, a part of an internal space thereof closer to the outer circumference thereof than an aeration unit is defined as a plurality of small spaces, and all of the small spaces have a uniform channel resistance, and all of the small spaces have a uniform ratio between a channel cross-sectional area at an inlet portion of each of the small spaces and a total opening area of nozzle holes that communicate the small space with an external space such that backflow water CF that returns from the respective small spaces consistently has a uniform flow rate at any point in time among the streams of the backflow water CF.
