Disclosed is a nozzle assembly for a sprayer, when a power of a sprayer is turned OFF, capable of not only minimizing an amount of liquid chemical remaining in a flow path at an inner side of a nozzle but also preventing backflow of the liquid chemical. The a nozzle assembly for a sprayer includes a nozzle assembly body molded in a ‘+’ shape; a nozzle assembled and installed in each of the plurality of nozzle assembly holes; a plurality of insert pieces fitting from an outside to an inside of four directions of a slide hole formed in a ‘+’ shape and forming a flow path for guiding a fluid flowing; and an end cap fixed and coupled to an outside in four directions of the slide hole in a state.

The present disclosure relates to an anti-splash water outlet structure. A water path core is provided in a water outlet body, a first water path is formed in the water path core, and a second water path is formed between the outer sidewalls of the water path core and the inner sidewalls of the water outlet body. The water outlet of the second water path surrounds the the water outlet of the first water path, and the water curtain flowing out of the second water path surrounds the water outlet of the first water path. The technical scheme of the present disclosure can avoid the splash of the water column while ensuring the water output of the kitchen faucet and the shower. It has the advantages of simple structure, low cost and good anti-splash effect.

The present disclosure provides a method for the surface modification of microstructured components having a polar surface, in particular for high-pressure applications. According to the method, a microstructured component is contacted, in particular treated, with a modification reagent, wherein the surface properties of the component are modified by chemical and/or physical interaction of the component surface and of the modification reagent.

Apparatus and methods for providing a desired volumetric conditioned airflow rate and for reducing noise level, airflow recirculation and airflow separation are disclosed. An example apparatus includes a nozzle housing having a pair of opposing sidewalls and a front and back wall that define an airflow passage. The airflow passage has a centerline extending between the inlet and the outlet and has a plurality of cross-sections taken perpendicular to the centerline that collectively define a smooth contour along a length of the airflow passage. The cross-sections each have a thickness between the front and back wall that is greater at side edges than at the centerline. The thickness of the cross-sections decreases along a length of at least a first portion of the nozzle housing. A width of each of the cross-sections between the sidewalls increases along the length of at least the first portion of the nozzle housing.

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.

An injection nozzle for a spray device for drawing in a fluid suction medium by a fluid propellant which is under excess pressure and for spraying an admixture of the suction medium and the propellant. The injection nozzle has a nozzle housing, an injection chamber arranged in the nozzle housing, a jet nozzle which opens in the injection chamber for producing a propellant jet which is introduced into the injection chamber, and a fluid suction opening for the fluid suction medium. The fluid suction opening opens in an annular channel which has a flow connection to the injection chamber.

A spray applicator (1) for spraying a fluid onto a web (W) of material has a first group of spray nozzles (10A) arranged along a first axis (FA) and a second group of spray nozzles (11A) arranged along a second axis (SA). The first (FA) and second (SA) spray nozzle axes are arranged on the same side of a plane in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray ozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).

The present disclosure relates to a soot blower including: a lance tube which includes one end that reciprocally moves in one direction on a surface of an inlet port of a flow path of the tubular heat exchanger; a drive unit which is connected to the lance tube and reciprocally moves and rotates the lance tube in the one direction; a first nozzle which is connected to the one end of the lance tube and discharges steam to the inlet port; and a second nozzle which is disposed adjacent to the first nozzle and connected to the one end of the lance tube and discharges solid particles to the inlet port, and the present disclosure relates to a method of cleaning a tubular heat exchanger by using the soot blower.

A toilet assembly includes a toilet body and a nozzle system. The toilet body defines a toilet bowl and a rim area disposed along an upper edge of the toilet bowl. The rim area includes a flange defining an opening. The nozzle system includes a nozzle having a first end configured to be fluidly coupled to a water supply conduit and a second end fluidly coupled to the rim area. The second end defines an outlet formed at a compound angle. The connector assembly detachably couples the nozzle to the flange such that the nozzle extends through the opening.
