A nozzle member (14) of a personal care device (10) comprising: a nozzle head (16) positioned at an end of the nozzle member; and an orifice (40) formed in a surface (30) of the nozzle head, wherein the orifice comprises at least one liquid jet orifice (42) configured to allow the liquid and/or air to exit the nozzle head in the form of a jet, and at least one liquid sheet orifice (40a-d) configured to allow the liquid and/or air to exit the nozzle head in the form of a sheet.

The present application discloses a water spraying pipe and a cleaning apparatus. The water spaying pipe includes a pipe body having a water inlet end and defining a water spraying hole in a pipe wall thereof; and a water spraying groove defined in the water spraying pipe at a position corresponding to the water spraying hole. The water spraying hole is in communication with the water spraying groove, and a diameter of the water spraying hole is greater than a width of the water spraying groove. The present application effectively improves the cleaning efficiency of the water spraying pipe.

An air nozzle includes a main body having a compressed air passageway to allow a compressed air to flow therethrough and a compensation air passageway in communication with the compressed air passageway. An external air is sucked into the compressed air passageway through the compensation air passageway and ejected together with the compressed air when the compressed air flows through the compressed air passageway.

The present disclosure is intended to provide a discharge apparatus and an industrial robot, discharge apparatus having a relatively simple configuration capable of removing a remainder of a discharge material remaining in a discharge nozzle and a feeding channel, enabling cost reduction, and having a structure which is easy to clean and with which a function of preventing drips can be imparted. The discharge apparatus includes: a nozzle head having a plurality of feeding channels for feeding a discharge material, and a removal channel communicating with the feeding channels and usable for removing a remainder of the discharge material remaining in the feeding channel; a plurality of discharge nozzles configured to be attached to the nozzle head such that each of the plurality of discharge nozzles is connected to an associated one of the plurality of feeding channels; a delivery tube configured to deliver the discharge material selectively to one of the plurality of feeding channels so that the discharge material is discharged from the discharge nozzle; and a suction tube connectable to the removal channel and usable for sucking the remainder of the discharge material remaining in the feeding channel and the discharge nozzle through the removal channel.

An elongated pool return for achieving high flow rates at low velocities is herein disclosed. The pool return generally includes an elongated main body and a slot box. In use, the pool return is mounted within a side wall of a pool such that a distal end of the slot box is exposed from the side wall, and fluid is permitted to flow into and through the main body, through the elongated slit, and through the slot opening, and into an opening of the pool. Because the pool return is elongated, large amounts of water can be displaced at low velocities.

An adjustable nozzle having a nozzle body having an inlet section with an inlet opening, an outlet section with an outlet opening, and a fluid flow path extending from the inlet opening to the outlet opening; a spray restrictor segment located in the outlet section; and an actuator that displaces the spray restrictor segment toward and away from a center of the fluid flow path, thereby varying a pattern of fluid flowing from the fluid flow path through the outlet opening.

A spray cap for a spray container includes a tubular wall for connection to the spring container, a cap plate in which a plurality of spray slits is formed and a valve to admit air into the space defined by the wall but which prevents the outflow of liquid from the space to the exterior. The cap plate includes a support plate of polymeric material in which an aperture is formed. An insert of more resilient polymeric material is retained in the aperture and forms a liquid-tight seal with the support plate. The spray slits are formed in the insert. The support plate and the insert define a liquid flow path between the space and the spray slits and include respective opposed annular sealing areas which are situated upstream of the spray slits and are biased into contact with one another by the resilience of the insert. When the spray cap is inverted and an increased pressure is produced in the space the pressure acts on the insert and the insert is thereby caused to deform such that the sealing areas move out of sealing contact and liquid can flow to the spray slits.

An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly (28) that includes a nozzle having a nozzle head (108). The nozzle assembly (28) also includes a baffle plate (101) including a cutout (144) that extends through the baffle plate (101), where the baffle plate (101) is received by the nozzle head (108) such that the nozzle head (108) and the baffle plate (101) define a cavity. The nozzle assembly (28) further includes a cover plate (102) attached to the nozzle head (108) such that the cover plate (102) secures the baffle plate (101) within the nozzle head (128), where an outlet passage is defined between the baffle plate (101) and the cover plate (102), the outlet passage being fluidly connected to the cavity through the cutout (144) of the baffle plate (101).

A spray head includes a nozzle, a sealing gasket, a first nut, and a screw. The nozzle includes an inlet portion, an outlet portion extending from an end of the inlet portion along an axial direction, and a first through hole penetrating the inlet portion and the outlet portion along the axial direction. The first through hole defines an opening on a surface of the outlet portion facing away from the inlet portion. The opening is rectangular. The sealing gasket is sleeved on the inlet portion. The first nut is sleeved on the nozzle and receiving the sealing gasket. The screw is located on a side of the sealing gasket facing away from the outlet portion and is engaged with the first nut. A second through hole penetrates the screw communicating with the first through hole. The disclosure also provides a cleaning device having the spray head.

A device is described for protecting a sensor window. The device includes a two-piece nozzle system and is configured for generating a first and a second fluid flow, a first piece of the two-piece nozzle system being fixedly situated with respect to the sensor window, and a second piece of the two-piece nozzle system being configured for assuming different positions with respect to the first piece of the two-piece nozzle system, and the two-piece nozzle system being aligned with respect to the sensor window to direct a predominant portion of the first fluid flow in parallel to the sensor window and to direct a predominant portion of the second fluid flow in the direction onto the sensor window.
