Abstract: A downrod assembly includes: an electric motor, an adapter subassembly and a downrod. The adapter subassembly is connected to an electric motor shaft of the electric motor; and the downrod is connected to the adapter subassembly and is capable of rotating with respect to the electric motor by means of the adapter subassembly. The downrod is able to be folded by rotating with respect to the electric motor during transportation, thereby reducing the overall packaging volume of a ceiling fan.

Abstract: A ceiling fan blade mounting structure includes a blade holding base and a fastening assembly. The blade holding base includes a plurality of connection members spaced apart from each other. The fastening assembly includes a wedging member, a rotating block, and a fastening member. The wedging member is fastened with one of the plurality of connection members. A first end of the rotating block is rotatably connected to the wedging member. A first end of the fastening member is rotatably connected to a second end of the rotating block. The fastening member is configured to rotate about the rotating block to cause a second end of the fastening member to be fastened with another one of the plurality of connection members.

Abstract: A ceiling fan assembly (100) including a downrod (10); a ceiling fan (20) connected to a lower end of the downrod (10); a connector base (30) mounted to the downrod (10) and located above the ceiling fan (20); and a receiver (40) having an internal mounting groove (40a) penetrating the receiver (40) in an up-and-down direction, the receiver (40) being located at the periphery of a central axis of the downrod (10) and detachably connected to the connector base (30).

Abstract: A ceiling fan blade structure and a ceiling fan. The ceiling fan blade structure includes: at least one fan blade provided with a first inserting portion; and a mounting plate provided with a second inserting portion, and being able to be detachably connected with the fan blade through a fit between the first inserting portion and the second inserting portion. The installation of the fan blade is changed, and the connecting members used in the existing mounting method of fan blades are removed. The fan blade is provided with the first inserting portion, the mounting plate is provided with the second inserting portion, and through corresponding insertion between the first inserting portion and the second inserting portion, the fan blade may be mounted to the mounting plate rapidly. Moreover, in a mounting process of the fan blade, a mounting operation can be completed without assistance of auxiliary tools.

Abstract: Disclosed are a Chinese website classification method and system based on characteristic analysis of a website homepage. The method specifically comprises the following steps: S1, crawling website content; S2, labeling a website type; S3, extracting website information; S4, calculating a weight and representing the weight in the form of a characteristic vector; and S5, classifying the website by comparing the characteristic vector. By utilizing the above Chinese website classification method and system, the noise interference can be alleviated to the greatest extent by only extracting a title and meta-information of the website; by means of pre-processing and characteristic vector expression, the characteristics of the website are accurately expressed with the vector, so that the accuracy of classification is increased; and since only the title and meta-information of the website need to be processed, the quantity of data to be processed is small, and the processing speed is high.
