Description

TECHNICAL FIELD [0001] The present invention relates to an industrial vacuum cleaner having a high-strength elastic member filtration device,

The present invention relates to an industrial vacuum cleaner provided with a high-strength elastic member filtering device, and more particularly, to a vacuum cleaner for industrial vacuum cleaners having a high-strength elastic member filtering device, To an industrial vacuum cleaner equipped with a high-strength elastic member filtering device having an improved structure.

In general, cleanroom cleaners are vacuum cleaners used in semiconductor manufacturing plants, LCD manufacturing plants, pharmaceutical laboratories, laboratories, clean rooms, intensive care rooms, and clean areas where fine dusts should not occur. Even a small amount of fine dust It refers to a vacuum cleaner used in places where it is bad and can interfere with research for many years.

FIG. 1 is a perspective view of a conventional industrial vacuum cleaner used in a general clean room, and FIG. 2 is a view showing a head structure of a conventional industrial vacuum cleaner used in a clean room. 1, a conventional industrial vacuum cleaner includes a vacuum cleaner body 10 including a head part 11 and a dust collecting tank 12, and includes a suction unit 13 connected to the suction port 13 of the vacuum cleaner body 10, Fine dust including foreign matter and dust in the clean area is sucked together with the air through the filter 14 and then the fine dust is collected by the filter so that only clean clean air filtered through the filter is discharged to the outside. As shown in Fig. 2, the head structure of an industrial vacuum cleaner used in a clean room is composed of a head cover 23 composed of an upper head cover 21 and a lower head cover 22, a motor for generating a suction force, A filter member 25 constituted by a motor member 24 having a structure in which the fan is coupled and a filter member 25 composed of a dual structure of a HEPA filter and an UL wave filter and a filter member 25 disposed on the upper portion of the upper head cover 21, A gasket 26 made of a rubber packing is provided to establish a firm close contact state. Further, a fixing bolt 27 is fastened and fixed to the upper center of the filter member 25 having a double structure of the HEPA filter and the ULPA filter.

That is, in a conventional industrial vacuum cleaner having a cleaner head structure as shown in FIG. 2, a filter member 25 composed of a HEPA filter and an UW filter is attached to an exhaust part where motor wind is blown to filter fine dust. At this time, the strong and hot motor wind (containing fine dust and motor carbon dust) continuously pushes the filter member 25 every time the vacuum cleaner is operated. As the use period elapses, the filter member 25 is closely contacted with the gasket 26 attached to the filter member 25 A fine gap is formed between the lower head cover 22 (motor heat-gasket expansion-contraction repetition of the gasket) to be an object to be supposed (conventional coupling method - rubber packing, bolt filling) Since the filter member 25 used may be discharged a large amount of fine dust before it is frequently inspected and replaced, the function as an industrial vacuum cleaner for use in a clean room in a clean room may be lost and become useless. That is, in an industrial vacuum cleaner used in an existing clean room, the coupling force between the gasket 26 and the filter member 25 weakens with the lapse of the period of use of the vacuum cleaner, and the fine dust is discharged through the fine cracks generated thereby. And strong and windy strong wind generated from the motor member 24 can be transmitted through fine gaps, resulting in a high level of noise. Korean Utility Model Registration No. 20-0445508 discloses a prior art example of a clean room vacuum cleaner.
