In one embodiment, a self-cleaning nozzle comprises a nozzle body, a sleeve surrounding a proximal end of the nozzle body, a pillar disposed within the nozzle body and a spring. The nozzle body may have a hollow cylindrical interior. The nozzle body may include an orifice formed in a distal end of the nozzle body, a shoulder formed on a proximal end of the nozzle body, and a first bearing surface on an outer lateral face of the shoulder. The sleeve may include a second bearing surface on an inner face of the sleeve and a retaining lip formed at a distal end of the sleeve. The retaining lip may define a distal end of an annular space between the sleeve and the nozzle body. The shoulder may define a proximal end of the annular space. The pillar may have a distal tip configured to interface with the orifice, thereby forming a liquid seal. The spring may be captured within the annular space, thereby biasing the distal tip of the pillar into contact with the orifice.

Furthermore, the cleaning device has a cleaning strip guide for feeding the free end of the cleaning strip to the yarn forming element of the air-spinning nozzle for mechanical cleaning.

This disclosure relates to a showerhead including a body, a stationary plate, a spring, and an insert fitting member. The body has an upper body and a lower body. The upper body and the lower body form an accommodation space. A water inlet for supplying water into the accommodation space is provided at the upper body, and a plurality of water outlets for spraying water from the showerhead are provided on the lower body. The stationary plate is located in the accommodation space and movable up and down in the accommodation space along a direction of the water flow. The spring is disposed between the stationary plate and the lower body, for applying a force to the stationary plate away from the lower body. The insert fitting member is fitted to the stationary plate. The position of the insert fitting member corresponds to the plurality of water outlets on the lower body. When the water is supplied, the stationary plate moves to a lower position under the action of water pressure, and the insert fitting member partially closes the water outlet to form a drizzle-type spray; and when the water is turned off, the spring pushes the stationary plate back to the upper position, and the water outlet plug leaves the water outlet.

A shower includes a fixed portion with a water outlet chamber. The fixed portion has a cover portion with a plurality of spouts for connecting to the water outlet chamber, and a movable portion including an operating member and a driving mechanism. The driving mechanism is drivingly connected to the movable portion and drives the movable portion to circulate, the movable portion is movably arranged in the fixed portion and comprises a movable plate and a plurality of protruding portion protruding on the movable plate, the protruding portion is inserted into the spout and there is a gap between the protruding portion and the spout, the operating member is drivingly connected with the movable portion and is driven by the operating member to move at least between the first position and the second position, and the movable portion discharges water differently in the first position and the second position.

An electrostatic spray apparatus includes: a voltage application device; a liquid spraying section including a nozzle for spraying a liquid a charged state by utilizing an electrostatic force generated by the voltage application device; and a coating prevention electrode for generating an electric field between the coating prevention electrode and a portion of the object to be coated on which the liquid is not to be coated. The voltage application device applies a voltage such that, when a potential of the object to be coated is a reference potential, a potential of the liquid spraying section assumes a first potential different from the reference potential, and a potential of the coating prevention electrode assumes a second potential. The second potential is a potential different from the reference potential, and a direction of polarity of the second potential is to the same as a direction of polarity of the first potential.

A shredder comprises one or more nozzle assemblies each including an elastic element configured to work in conjunction with the nozzle and the nozzle housing such that the nozzle is held in the home position when in an unloaded rest condition and as a result of an impact temporarily moves in the direction of the impact position.

One general aspect includes a liquid dispenser with a mount having a mount aperture. A liquid flow path assembly is removably secured to the mount and has an inlet configured to receive liquid, an outlet configured to dispense liquid and a passageway fluidly coupling the inlet to the outlet. A third aperture apart from the inlet and the outlet is fluidly coupled to the passageway and forming a valve guide. The liquid flow path assembly is disposed on the mount to align the third aperture with the mount aperture. An elongated valve has a valve stem guided by the valve guide and extends through the third aperture and the mount aperture. A latch assembly secures the liquid flow path assembly to the mount.

The electrostatic spray device includes a liquid sprayer including a nozzle that spouts a liquid; a voltage applicator that applies a voltage between the liquid sprayer and a heteropolar portion functioning as a pole opposite a pole of the liquid sprayer to generate an electrostatic force for causing the liquid to separate from a distal end of the nozzle in a charging state; and a stabilization electrode that maintains a stable spraying state of the liquid even when a pressure is applied to the liquid to supply the nozzle with the liquid. The stabilization electrode has an electric potential identical to an electric potential of the liquid sprayer, and is disposed near the nozzle such that a jet portion formed at a front of the nozzle by a linear extension of the liquid has a length longer than a length of the jet portion before the stabilization electrode is provided.

An electrostatic spray device including a voltage applicator and an isoelectric line adjustment electrode. The voltage applicator applies a voltage between a liquid sprayer and a heteropolar portion functioning as a pole opposite from a pole of the liquid sprayer to generate an electrostatic force. The isoelectric line adjustment electrode is made from a conductive material and adjusts equipotential curves appearing so as to surround the nozzle. The isoelectric line adjustment electrode obtains the equipotential curves at least partially drawing curvature gentler than curves of equipotential curves appearing near a front side of the nozzle in a state where the isoelectric line adjustment electrode is not disposed. The isoelectric line adjustment electrode is located near an outer periphery at a distal end of the nozzle and has an electric potential identical to an electric potential of the liquid sprayer such that the equipotential curves drawing the gentle curvature are obtained.
