Abstract: An electric mini push cart provided includes a cart frame, an operation platform, a bucket, and a hydraulic power device. The operation platform arranged on the rear side. The bucket is configured to load objects and located on one side of the operation platform. The hydraulic power device drives the bucket to turn over, the hydraulic power device is installed on the cart frame and located below the bucket, the hydraulic power device includes a piston rod connected to the first end. When the hydraulic power device is working, the piston rod is stretched or retracted to push or pull back the first end, so that the bucket turns around the second end, and moves away from the operation platform or falls back towards the operation platform.

Abstract: Provided are a cleaning machine, a cleaning device, an information display method thereof, and a storage medium. A display is additionally arranged on a main body of the cleaning machine to display working state information of at least one component on the cleaning machine, thereby visually displaying a working state of the cleaning machine. A user may know about a working state of a component on the cleaning machine visually, which contributes to improving user experiences.

Abstract: The present invention discloses a data storage space processing method and processing system, and a data storage server. The data storage space processing method includes: dividing a disk and memory resource into tablets; dividing memory space of a tablet into different logical objects; and dividing, according to a fixed size, disk space of the tablet into multiple data blocks that are of a same size. According to the data storage space processing system and method provided in embodiments of the present invention, a disk and memory resource on a storage server is divided into independent tablets, and the tablets are used as basic service resource allocating and managing units, which can implement multiplexing of a single-node resource on multiple services. Besides, by using hybrid indexing and associated write combining and block recycling technologies, random write IOPS of a system is improved, and index memory space can also be significantly saved.
