The present disclosure provides, a cleaner hanger assembly, including a hanger, a charging bottom plate, an accessory frame, a hanger column and a base. The charging bottom plate can be used in cooperation with the hanger, so that a charging operation can be performed while the cleaner is hung on the hanger whether the cleaner is in a hanging state or in a floor-standing state, and the charging bottom plate can also be detached for separate use. The hanger can be connected to the accessory frame to form a wall hanger assembly; or the hanger can be connected to the base by means of the hanger column and the accessory frame is fixed in the middle of the hanger column to form a floor-standing hanger assembly.

Cleaner hanger assembly

The disclosure provides a rechargeable battery pack, applicable to a handheld vacuum cleaner, including: a polymer cell, comprising at least one polymer cell unit; a charger input terminal, electrically connected to the polymer cell, wherein the polymer cell is charged through the charger input terminal; a power interface, electrically connected to the polymer cell, and configured to supply power to the handheld vacuum cleaner when the rechargeable battery pack is connected to the handheld vacuum cleaner; and a protective circuit module (PCM) board. A handheld vacuum cleaner is further provided herein.

A method for providing one or more search suggestion candidates for an input key comprises: (1) acquiring characteristic information of the input key; (2) creating a characteristic DFA (Deterministic Finite Automaton) of the input key based on the characteristic information of the input key; (3) searching the characteristic DFA of the input key in a predetermined database DFA having a plurality of bridge transitions each linking a bridge head state with a bridge tail state, so as to identify a bridge head state that matches the characteristic DFA of the input key, wherein each bridge head state of the predetermined database DFA corresponds to a final state of a characteristic DFA of a target candidate which is created based on characteristic information of the target candidate; and (4) outputting one or more target candidates corresponding to a bridge tail state linked with the identified bridge head state as the search suggestion candidate for the input key.

Method for providing search suggestion candidates for input key and method for creating database DFA

According to one aspect of the present application, a method for data compression comprises: creating a first trie for a first set of strings, the first set of strings comprising a plurality of raw data strings, wherein a trie consists of a plurality of nodes linked through parent-child relation, and wherein each edge of the trie is of at least one character and the edge corresponds to a state transition from a parent node of the edge to a child node of the edge; collecting edges of the first trie longer than a predetermined length and making these edges a first subset of strings of the first trie; segmenting a string in the first subset of strings into two or more fragments when the string satisfies a predetermined condition and collecting all segmented fragments and all un-segmented strings in the first subset of strings as a segmented set of strings; and storing the first set of strings using the first trie and the segmented set of strings so as to compress the raw data strings.
