VACUUM CLEANER CAPABLE OF IMPROVING SUCTION FUNCTION

摘要

PURPOSE: A vacuum cleaner is provided to remove or purify impurities by properly setting an air spraying speed, a suction speed, an air purifying function, an air spraying angle of the vacuum cleaner. CONSTITUTION: A vacuum cleaner includes a suction part(1) for sucking impurities, an extension pipe(2) for guiding air to be sucked or sprayed, and a shrinking part(3) for guiding impurities towards a dust collecting chamber. A partition member(4) is provided to introduce impurities into the dust collecting chamber while preventing impurities from reversely flowing. The impurities are purified by a filter(5). A blowing fan is provided to suck impurities or to discharge purified air. Purified air is sprayed through a spraying circuit section(7). A spraying section(8) is formed with spraying holes for forming an air curtain or swirl air flow. The blowing fan is operated by a motor.
