Description

Suction nozzle of vacuum cleaner with dust container

The present invention relates to a suction nozzle of a vacuum cleaner equipped with a dust container, and more particularly, to a suction nozzle of a vacuum cleaner equipped with a dust container installed in front of a suction port of the vacuum cleaner to filter out fine dust primarily. .

In general, a vacuum cleaner is a vacuum cleaner that sucks dust using suction power generated by a pen installed on a main body, and has become an essential household appliance due to its advantages of ease of use and excellent cleaning efficiency.

For example, the dust introduced by the suction force of the main body is separated from the air in a state of being filtered by the filter and collected separately, wherein the filter has a mesh structure so that the air passes quickly while the dust does not pass and is filtered out. Smaller dusts of 0.3 ~ 0.5㎛ size were caused to be discharged into the indoor air.

Therefore, in the related art Utility Model Publication No. 1998-0015512 (name: installation structure of the vacuum cleaner filter), the first composite filter in which the first filter and the first fine filter are integrally disposed at the rear of the dust collecting pack is provided. The rear part of the motor has a second composite filter in which the second filter and the second fine filter are integrally provided, and a technique for preventing re-emission of fine dust has been disclosed.

Due to this double filter structure, not only the odor generated from the fine dust and foreign matter sucked during vacuum cleaning is removed by the first composite filter, but also the fine dust and odor generated from the motor that are not removed from the first composite filter are removed. Although it is removed by the second composite filter, it is difficult to see that the actual fine dust emission is completely controlled, and in the home equipped with a vacuum cleaner, there is no great effectiveness due to the burden of purchasing a vacuum cleaner again. In addition, when used for general floor cleaning, relatively large particles of foreign matter are excessively trapped in the first composite filter, preventing the air from being transferred, and the second composite filter lowers the air discharge rate to the outside. This is greatly reduced and there is an inconvenience in that the filter must be replaced and washed frequently during cleaning.

On the other hand, in addition to the above-described technology, in order to clean the foreign substances such as dust, mites, etc., the suction nozzles, which have been improved in various forms, are sold and sold on the market. Due to the characteristic of the suction structure, which is forced out through the filter, the air gap of the filter is expanded due to the high discharge pressure, so that invisible fine dust of about 0.3 ~ 0.5㎛ cannot be filtered out and most of it is re-extracted in the air. After use, the degree of indoor air pollution was severe and caused serious adverse effects on the human body (eg, asthma, allergic rhinitis, respiratory diseases).

The present invention has been made to solve the above problems, the cleaning efficiency is improved by simply replacing the suction nozzle of the vacuum cleaner used in the existing, as well as the dust collection is easy, the source of the dust container such as fine dust It is an object of the present invention to provide a suction nozzle of a vacuum cleaner equipped with a dust container, which filters the dust, such as dust, which is sucked into the vacuum cleaner main body, thereby greatly reducing the dust discharge to the outside of the vacuum cleaner main body. .
