Description

Dust collector

The invention relates to a dust collector used for decoration or woodworking, in particular to a dust collector and dust collector with multiple partitions to retain dust or foreign matter, and has the function of filtering air.

A vacuum cleaner is a type of vacuum cleaner that is configured to use suction to introduce air and filter and collect foreign matter, dust, and fine dust contained in the air. The types of vacuum cleaners can be divided into (i) horizontal (canister type); (ii) vertical (Upright type); (iii) hand type; (iv) cylindrical floor type (cylindrical floor type), etc.

The horizontal vacuum cleaner is a vacuum cleaner most commonly used at home in recent years, and has a structure in which the suction unit and the cleaner body are separated from each other. Generally, horizontal vacuum cleaners are not provided with a rotating brush and are suitable for cleaning floors, because when cleaning, air is only sucked by a suction unit.

On the contrary, an upright vacuum cleaner is a vacuum cleaner having a structure in which a suction unit is integrated and formed in a cleaner body. Generally, a vertical vacuum cleaner can be equipped with a rotating brush. Therefore, unlike a horizontal vacuum cleaner, it has the advantages of being able to clean the dust in the carpet.

However, the conventional vacuum cleaner has the following disadvantages:

First, the structure of the vacuum cleaner as disclosed in Korean Patent Publication No. 10-2003-0081443 (published on October 17, 2003) has a multi-stage cyclone structure, and each cyclone is arranged vertically to cause dust collection The height of the device increases. In addition, the dust collector is designed to have a slim profile to solve the problem of this increase in volume, thus leading to the disadvantage of reducing the volume of the space for collecting actual dust.

In order to solve the aforementioned problems, as disclosed in Korean Patent Publication No. 10-2004-0023417 (published on March 18, 2004), a structure in which a second cyclone is provided in a first cyclone is proposed. However, due to the interference between the guide channels provided in each second cyclone separator, it is difficult to effectively install the second cyclone separator in the first cyclone separator. Even if the second cyclone separator is provided in the first cyclone separator, the number of the second cyclone separator is greatly reduced and the suction force is reduced, resulting in a decrease in cleaning performance.

In addition, various flows including the high-speed rotating flow generated by the suction force of the fan unit are mixed in a dust collector. This complicated flow may hinder the introduction of foreign matter and dust into the first storage area, and may cause the dust collected in the first storage area to rise and flow back upstream.

According to circumstances, such as the structure disclosed in Korean Patent Publication No. 10-2004-0023417 (published on March 18, 2004), in order to avoid foreign matter and foreign matter stored in the first storage area located below the first cyclone The dust is scattered, and a side skirt can also be set in it. Because the part where the side skirts are formed will form a small gap with the housing, foreign matter may get stuck in the gap. When foreign objects are stuck in the gap, other foreign objects and dust cannot flow into the first storage area through the gap.

In addition, when foreign matter and dust collected in the first storage area accumulate, they approach the first cyclone side slowly and efficiently, especially the bulky foreign matter, even when it is collected in the first storage area, there will be no The gathering shape is scattered in the first storage area, causing the dust accumulation part to flow back in the upstream direction.

On the other hand, most of the foreign matter or dust that did not pass through the first cyclone falls and is collected in the first storage area, but in some cases, the foreign matter or dust will be captured or accumulated and fixed to a screen. Filter, which reduces the area of air passing through the screen filter, thereby increasing the load on the fan unit that provides suction and giving the user a visually unclean impression.

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventor of this case wants to solve; yes, the inventor of this case is based on years of experience in the relevant industry, after years of painstaking research, trial improvements, and finally Successfully researched and developed this case and gave birth to the present invention to improve the efficacy.

In view of the above shortcomings, the dust collector of the present invention includes: a first container, a vacuum motor, a first guide unit and a second guide unit, the first container is provided with a first tube body, The vacuum motor is arranged on a cover, the motor is provided with a filter, the first guide unit is arranged on the bottom surface of the cover, and is combined with the second guide unit, the first guide unit and the second guide unit A second container and a third container are detachably combined, and the second guide unit is located in the first guide unit, and the first pipe body sucks in air to make dust and debris in the air Entering the first container, the air sequentially passes through the first guide unit and the second guide unit to form a vortex, causing the finer dust to fall into the second container and the third container, and finally pass through the filter before being discharged by the vacuum motor air.
