Vacuum Dust Collector

Abstract

A vacuum dust collector comprising a housing including a concaved space inside and a control knob on the top; an suction generator placed under the concaved space; a bottom cover, covered at the bottom of the housing, including a dust inlet and at least one sensor; and a dust container, disposed in the concaved space, including a cover, a chamber, a filter, an outlet pipe, an inlet pipe, and a latch. Moreover, the shape of the housing is corresponding to the place where it is located, and the latch is pressed by the filter disposed on the outlet pipe of dust container to allow the cover to be eclipsed on the chamber.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a vacuum cleaner, more particularly to a vacuum dust collector.BACKGROUND OF THE INVENTION[0002]Conventionally, the cleaning procedure requires the user to sweep the debris and dust into a pile and use a collection device such as dustpan to pick up the debris and dust. But dust flies in the air easily when swept, and the user might feel uncomfortable. However, it is not easy for the user to collect all dust and dump into a waste container precisely, results in the poor efficiency and high demanding efforts.[0003]According to U.S. Pat. No. 6,671,924 B1 which is published on Jan. 6, 2004, titled “Vacuum Dustpan” disclosed a vacuum dustpan having a housing with an inlet to the level of the floor surface into which dust and debris can be directed. The vacuum dustpan is equipped with a vacuum motor which transfer the debris to a collection chamber within the housing. However, the poor control over usage results in inconvenience...

AI Technical Summary

Benefits of technology

[0005]The primary objective of the present invention is to provide a vacuum dust collector which has a shape fits or corresponding to the place where it is located. Thus, space usage of the vacuum dust collector can be more efficiency.

[0010]The latch is an L-shape structure with a block at the long edge and an extending portion at the short edge. When the filter is not installed on the outlet pipe, the block is leaned against the inner surface of the chamber to prohibit the cover from being eclipsed on the chamber. Once the filter installed on the outlet pipe, the extending portion is pressed by the filter and the block is departed from the inner surface of the chamber. The block leaves a gap for the cover to be eclipsed on the top of chamber. Thus, the cover can seal the chamber.

[0011]Accordingly, the dust container can not be put in the housing when the cover is not eclipsed on the chamber completely. In other words, the latch is adopted as a secured device to prevent the vacuum dust collector from being used without the filter.

Problems solved by technology

But dust flies in the air easily when swept, and the user might feel uncomfortable.

However, it is not easy for the user to collect all dust and dump into a waste container precisely, results in the poor efficiency and high demanding efforts.

However, the poor control over usage results in inconvenience for the user while cleaning.

Nevertheless it is only required the user press the switch, and the vacuum motor turned on without an auxiliary instrument to assure whether the filter is installed or not, even the vacuum motor may be damaged by dust and dirt.

Moreover, it is hard to arrange space efficiently for the shape of the vacuum dustpan may occupy too much room or not fit perfectly to where it is located.
