Abstract: This application discloses a shower assembly and a two-in-one coffee machine, including a main structure, a shower head, and a needle assembly. The shower head is mounted on the main structure in a manner that can move relative to the main structure, and the shower head has a first position away from the main structure and a second position close to the main structure. When the shower head is located at the first position, water from a water inlet channel flows out through shower holes. When the shower head is located at the second position, a water outlet channel is in sealed communication with the water inlet channel, a needle outlet is located below the shower head, and water in the water inlet channel flows out through the needle outlet. The shower assembly in the present disclosure can form two spraying paths by switching the position of the shower head.

Abstract: A one-click data processing method for digitalized aerial image includes acquiring all aerial images captured by an unmanned aerial vehicle (UAV) in an aerial-photographed area and performing filtering sequentially on each aerial image, constructing a high-precision calibration test-field, determining a distortion correction parameter of a to-be-calibrated camera outfitted to the UAV based on the high-precision calibration test-field, and performing lens distortion correction on each filtered aerial image based on the distortion correction parameter, performing aerial triangulation, obtaining exterior orientation elements of each aerial image based on an aerial triangulation result, determining an orthophoto corresponding to each aerial image based on the exterior orientation elements, and stitching, using an image stitching algorithm, orthophotos corresponding to respective aerial images together into an orthophoto of the aerial-photographed area.

Abstract: A method for pattern recognition of a partial discharge defect type includes, by resolving the degree of correlation between respective electrical characteristics during operating, synchronously obtaining criticality indexes of the electrical characteristics based on the resolved degree, synchronously obtaining numerical lines of individual electrical characteristics based on the continuous, non-interrupted characteristic of operating of the electrical loads under test, and calibrating the numerical partial discharge defect index obtained using the ISODATA method based on the numerical probability.

Abstract: Provided is a device for processing an antistress cone of a main insulation layer of a cable. The device includes a support, a clamping unit, a cutting unit and an infeed unit. The clamping unit is mounted on the support and configured to clamp a cable. The cutting unit is slidably disposed on the support, capable of cutting the cable in the radial direction of the cable, and capable of performing feeding in the radial direction of the cable to adjust the cutting depth. The infeed unit is connected to and capable of driving the cutting unit and configured to drive the cutting unit to slide in the axial direction of the cable so that the cutting unit performs feeding and cutting in the axial direction of the cable.

Abstract: The present disclosure relates to the technical field of cable processing, and discloses a method for processing a reaction force cone of a cable main insulating layer. The method includes: two ends of a cable are clamped through a clamping device, and the cable is enabled to pass through a cutting device; a cutting depth of the cutting device in a radial direction and a cutting position of the cutting device in an axial direction are adjusted; the cutting device is started, and the cable is cut by the cutting device to form the reaction force cone.

Abstract: The application discloses a coffee maker cover and a capsule coffee maker.
