An apparatus for manufacturing a display apparatus includes a deposition source, a nozzle head, a substrate fixer, and a deposition preventer. The deposition source is outside the chamber and vaporizes or sublimates a deposition material. The nozzle head is in the chamber, is connected to the at least one deposition source, and simultaneously sprays the deposition material onto an entire surface of a display substrate. The substrate fixer is connected to the chamber and moves linearly, with the display apparatus is mounted on the substrate fixer. The deposition preventer is in the chamber surrounding an edge portion of the nozzle head and an edge portion of the substrate fixer. The deposition preventer is heated during a deposition process.

A nozzle includes an inlet end having one or more inlet apertures and an outlet end having one or more outlet apertures. The nozzle includes a body member that extends between the inlet end and the outlet end. In some embodiments, the nozzle includes a central member that extends centrally through the body member. The nozzle includes an end member fixedly coupled with the central member at the outlet end. The nozzle includes a slidable member translatably coupled with the central member. The slidable member is configured to direct fluid that flows through the body member outwards towards an inner surface of the body member and translation of the slidable member adjusts a K-factor of the nozzle.

The present disclosure provides a self-traction wire coating robot and a wire routing and wire hanging method, wherein the robot includes a mounting plate, a material pushing module, a winding traction module, a coating module, a walking module and a power supply and control module, wherein the coating module and the walking module are rotatable in the extension direction of the non-overhead bare wires, when hanging wires, the coating module and the walking module are first rotated and swung to the side of the robot, an unmanned device is then used to hang a traction belt on the overhead bare wires, the winding traction module tightens the traction belt to hang the robot under the overhead bare wires, and then the coating module and the walking module are controlled to rotate and recover to the top of the robot and hang the robot on the overhead bare wire.

A water ejecting apparatus includes a case and a water ejection unit connected to one side of the case. The water ejection unit includes a fixed cover, a lifting cover, a lifting motor, a water ejection nozzle, a touch bar, a detection sensor, and a controller. The fixed cover is connected to the case. The lifting cover is movably received in the fixed cover and coupled to the lifting motor. The water ejection nozzle is installed at a lower end of the lifting cover and configured to eject water. The touch bar is at least partially received in the lifting cover and moves when in contact with a container placed below the water ejection nozzle. The detection sensor detects movement of the touch bar. The controller changes operation of the lifting motor when the detection sensor detects movement of the touch bar.

A spray washing component for a smart toilet cover and an assembly method thereof are provided. The spray washing component includes a base, a nozzle, and a first motor. A sliding track is disposed on the base. The nozzle has a rack cooperating with the first motor. The first motor drives the nozzle to slide along the base. The first motor is installed at an end away from a jet of the nozzle and drives the nozzle to be displaced through a transmission structure. The transmission structure includes a driving gear, a dual transmission gear, and a conveyor belt. The driving gear is in anti-rotation cooperation with an output shaft of the first motor. The dual transmission gear respectively meshes with the conveyor belt and the rack on the nozzle. The spray washing component and the assembly method solve the large space occupation and insufficient aesthetics of the existing toilet.

A pitch-yaw actuation system includes a pitch frame, a yaw frame, a pitch actuator, a yaw actuator, and a universal joint assembly. The pitch frame is pivotably coupled to a device frame via a pitch hinge. The yaw frame is pivotably coupled to the pitch frame via a yaw hinge. The pitch actuator pivots the pitch frame about a pitch axis. The yaw actuator pivots the yaw frame about a yaw axis oriented orthogonal to the pitch axis. The universal joint assembly couples the yaw actuator to the yaw frame, and includes a universal joint slidably coupled to a linear guide mechanism. The guide mechanism axis is oriented at an angle that allows the universal joint to move in a manner accommodating misalignment of the yaw actuator with the yaw frame during pivoting of at least one of the pitch frame and the yaw frame.
