Suction nozzle structure for vacuum cleaner

Abstract

The present invention provides a floor nozzle structure of dust cleaner. Its structure comprises a suction inlet placed on the undersurface of floor nozzle and used for sucking refuse and a suction channel which is connected with suction inlet for guiding the refuse to suction inlet and is recessed to a certain depth, the plane projection of the described suction channel is characterized by setting at least more than two suction channels whose suction direction is tangential to the suction inlet. Besides, said invention also provides two other floor nozzle structures, their common feature lies in that these floor nozzle structures can greatly raise the suction force for sucking air so as to raise the performance of dust cleaner.

Description

Technical field [0001] The present invention relates to a suction nozzle structure of a vacuum cleaner, and particularly relates to a suction nozzle structure of a vacuum cleaner that improves the shape and position of the suction channel and the suction port to improve the performance of the vacuum cleaner. Background technique [0002] Generally, vacuum cleaners such as figure 1 As shown, it includes: a fuselage with a suction fan that generates suction force 1, an inhalation hose connected to the front of the fuselage 1 and sending out foreign objects sucked from the bottom surface 2, connected to the other end of the suction hose 2 with The user can select the handle 3 of the selection key of the cleaning mode, the extension tube 4 connected to the other end of the handle 3, and the suction nozzle 5 connected to the end of the extension tube 4 to suck foreign matter on the surface to be cleaned. [0003] Nozzle 5 as figure 2 As shown, a suction port 5a is provided in the ce...

Problems solved by technology

[0007] However, in the existing suction nozzle structure, the suction channels 5b and 5b that constitute the absorption area are in a linear structure, which not only makes the entire absorption area too small, but also the air flow of the suction channels 5b and 5b on both sides is generated at the suction port 5a. conflict with each other, resulting in loss of flow

[0008] Moreover, only a strong vacuum phenomenon is generated around the suction port 5a and the suction passage 5b, 5b, while other parts cannot be closely attached to the surface to be cleaned, thus reducing the cleanability

There is no structure in the cleaning surface to attract particles such as fine sand, thus reducing the cleaning efficiency
