The present disclosure discloses a self-cleaning water outlet device, which comprises: a body, a deposit removal needle plate disposed in the body, a water outlet cover comprising a plurality of water outlet holes, and a rotatable member driven about an axial direction of the rotatable member by flowing water. An axial direction of the deposit removal needle plate and an axial direction of the water outlet cover are coaxial, and the deposit removal needle plate has a plurality of needles. The deposit removal needle plate is swingably connected with the rotatable member. When water flows into the water outlet device, the water flow drives the rotatable member to rotate, and the rotatable member drives each of the plurality of needles to swing about the axial direction of the deposit removal needle plate in a corresponding one of the plurality of water outlet holes.

A precision cleaning device for cleaning and clearing a glue-dispensing needle includes a base, a supporting unit disposed on the base, a moving unit movably connected to the supporting unit, a clearing needle connected to the moving unit and facing the supporting unit, and an adjusting unit connected to the moving unit. The adjusting unit adjusts a movement of the moving unit to drive the clearing needle to move towards the glue-dispensing needle on the supporting unit, allowing the clearing needle to pass through the glue-dispensing needle to completely clean and clear the glue-dispensing needle. The cleaning device also prolongs the service life of the glue-dispensing needle.

The present disclosure discloses a self-cleaning device and a water outlet device. The self-cleaning device comprises a liquid flow chamber, one or more ejector pins, and an elastic deformation body. The self-cleaning device is configured to remove scale in one or more liquid outlet holes of the self-cleaning device automatically.

Systems and methods for inspecting and cleaning a nozzle of a dispenser are disclosed. The systems may include a platform supporting a cleaning substrate. The cleaning substrate may have a plurality of hook structures configured to remove a material from the nozzle. The systems may also include a camera configured to capture an image of the nozzle and a controller configured to control the system. The methods may include providing a cleaning substrate having a plurality of hook structures, and moving at least one of the nozzle and the cleaning substrate relative to the other to remove a material from the nozzle. The methods may also include capturing an image of the nozzle after dispensing with a camera, processing the image to generate a value, utilizing the value to determine if the nozzle should be cleaned, and if the determination is that the nozzle should be cleaned, cleaning the nozzle.

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.

Provided is a cleaning device, comprising a wiper, a first clamping plate, a second clamping plate, a first elastic clamp and a second elastic clamp. The first clamping plate comprises a first plate body, a first bent portion and a first end portion. The first bent portion extends between the first plate body and the first end portion in a bent manner. The second clamping plate comprises a second plate body, a second bent portion and a second end portion. The second bent portion extends between the second plate body and the second end portion in a bent manner. The wiper is positioned between the first clamping plate and the second clamping plate. The cleaning device is moved relative to the nozzle to wipe the nozzle for cleaning. The wiper will not generate pollution and basically causes no wear to the nozzle.
