This invention relates to the field of centrifugal fan technology, and particularly to a high-pressure centrifugal fan with backward-curved blades. The fan includes a volute, an impeller, and a collector. Both the impeller and the collector are housed within the volute, and the collector is fixedly connected to the volute. The impeller includes a front plate and a rear plate. Multiple blades are arranged in an array around the rear plate. An air intake is located in the center of the front plate. The blades are of a single-plate straight structure, each blade including a leading edge, a trailing edge, a first side connecting the first end of the leading edge and the first end of the trailing edge, and a second side connecting the second end of the leading edge and the second end of the trailing edge. The first side is the side closest to the air intake, and the second side is the side furthest from the air intake. The leading edge includes an arc segment near the air intake and a straight segment away from the air intake. The trailing edge is a straight segment. Both the straight leading edge and the trailing edge are parallel to the impeller hub, and the second side is perpendicular to the impeller hub. This high-pressure centrifugal fan has a larger flow rate and higher pressure.

The application relates to the field of automobile technology, in particular to a self-cleaning method and device of an automobile air conditioner, wherein the method comprises the following steps: after entering an air conditioner self-cleaning mode based on an air conditioner self-cleaning instruction, controlling the automobile air conditioner to enter a frosting mode and continuously operate for a first preset duration; after continuously operating for the first preset duration, controlling the automobile air conditioner to enter a defrosting mode and continuously operate for a second preset duration; after continuously operating for the second preset duration, controlling the automobile air conditioner to enter a ventilation mode and continuously operate for a third preset duration; and until receiving an end instruction in the automobile air conditioner or operating for the third preset duration, exiting the air conditioner self-cleaning mode. According to the application, the self-cleaning of the automobile air conditioner can be realized according to the user instruction based on the frosting, defrosting and ventilation modes of the automobile air conditioner, so that the cost of air conditioner cleaning is reduced, the equipment safety of the air conditioner is guaranteed, the self-cleaning efficiency of the automobile air conditioner is improved, and the application is more simple, practical and convenient.

The application provides a motion control method of a fan, which comprises the following steps: obtaining a preset motion stage of the fan and an operation parameter of the fan in the preset motion stage; and controlling the fan to perform acceleration motion, uniform motion and / or deceleration motion according to a preset jerk parameter and other parameters in the operation parameter in the preset motion stage. The application controls the stage duration of the stage in which the absolute value of the jerk parameter of the fan in the motion stage is a non-maximum value to be infinitely close to 0 by obtaining each motion stage in the preset motion stage of the fan and the jerk parameter in the operation parameter of the fan, and controls the fan to perform acceleration motion, uniform motion and / or deceleration motion in the preset motion stage in combination with other parameters, so that the fan moves at a maximum absolute value of the jerk in the entire motion stage, the centrifugal force of the fan is approximately kept at a maximum value, and the self-cleaning efficiency of the fan and the use experience of a user are improved.

This utility model discloses a self-cleaning dust collector, relating to the field of dust collector technology. In use, the housing is placed on top of the hopper, with the lower cavity communicating with the hopper. A negative pressure device is connected to the negative pressure interface. During operation, a negative pressure environment is created inside the housing, causing dust in the hopper to enter the lower cavity under pressure differential. The airflow passes through the filter cartridges, where dust is trapped on the surface. When excessive dust adheres to the surface of the filter cartridges, compressed gas is sprayed into the inner side of the filter cartridges via the main pulse pipe and auxiliary pulse pipe. The high-pressure air from the inside of the filter cartridges blows the dust adhering to the surface into a pre-set dust collection hopper below. Meanwhile, high-pressure air from the outside of the filter cartridges is blown obliquely towards the outer surface, removing firmly adhered impurities from the filter cartridge surface, thus improving self-cleaning efficiency and achieving the purpose of dust collection.

The invention relates to the technical field of intelligent household appliances, and discloses a cleaning base and a self-moving robot, the self-moving robot is matched with the cleaning base for use, the self-moving robot comprises a driving wheel and a collision plate, the cleaning base comprises a base and a charging seat, a cleaning area is arranged on the base, and the charging seat is arranged on the cleaning area. The collision plate is arranged on the base and used for allowing the driving wheels to execute a cleaning task, the charging base is arranged on the base and used for being in butt joint with the self-moving robot to execute a charging task, and the collision plate is kept in an open state in the charging task process and kept in a closed state in the cleaning task process. The collision plate is kept in the closed state in the cleaning task process, so that the robot can smoothly advance to abut against the cleaning base, and the driving wheels are automatically cleaned through autorotation of the driving wheels in the cleaning area.
