    摘要: A fan and a cleaning device are provided. The fan has a housing assembly, a fan cover, a wind wheel, and a first diffuser. The fan cover is mounted on the housing assembly and fits with the housing assembly to form an accommodating cavity. The wind wheel is provided in the accommodating cavity and fits with a side wall of the accommodating cavity to form an air inlet channel. The first diffuser is provided in the accommodating cavity, and has first fan blades and a mounting hub. The mounting hub, the first fan blades and the side wall of the accommodating cavity together provide a first diffusion channel. The air inlet channel is in communication with the first diffusion channel in series.

    摘要: A portable blowing device includes a body and fans arranged in the body. Air channels are arranged in the body and extend in the length direction of the body to allow airflow to pass through. Wind shields are arranged in the air channels, and a periphery of the wind shield is closely connected with a side wall of the air channel so that a sub-air channel is formed between the wind shield and the side wall of the air channel. Air outlets are formed in the side wall for communicating with outside and the sub-air channel, and airflow generated by the fan can enter the sub-air channel and then exits the air outlets. Because of the reduced volume of the sub-air channel, the airflow is concentrated after entering the sub-air channel, and airflow exiting the air outlets is strengthened, so that the cooling effect and the user experience are improved.

    摘要: An electric blower and a cleaning apparatus are provided. The electric blower includes a shell assembly, a wind cover, a rotary impeller and a diffuser. A stator assembly and a rotor assembly are provided inside the shell assembly. The wind cover is connected to the shell assembly. The rotary impeller is located inside the wind cover, and is connected to a rotating shaft of the rotor assembly. The diffuser is arranged at the end of the shell assembly, which faces the wind cover, and is located between the rotary impeller and the shell assembly. An outer wall of the shell assembly is provided with a cylindrical portion. Multiple circumferentially distributed mounting support legs are provided at the end of the cylindrical portion, which faces away from the wind cover. The mounting legs are used to fit with an assembly structure of a cleaning apparatus.

    摘要: A centrifugal blower includes a box, a filter, an impeller, a scroll casing, a bell mouth, a partition wall, and a separation tube. The scroll casing defines an air passage gradually increasing from a nose portion in a circumferential direction. The partition wall divides the air passage into an upper passage and a lower passage. The separation tube includes an air introducing plate to partially cover the impeller and defining an air inlet portion and a tubular portion that extends from the air inlet portion through the impeller. On a virtual plane parallel to a rotational axis of the impeller, an outer edge of the air introducing plate extends and a passage between the filter and the upper passage is divided by the separation tube into a first passage cross-section closer to the nose portion and a second passage cross-section that is smaller than the first passage cross-section.
