Description

Industrial vacuum cleaner having automatic filter structure

The present invention relates to an industrial vacuum cleaner having an automatic filter structure, and more particularly, to a drum type vacuum cleaner, which improves a mounting structure of a filter installed inside to filter fine dust, thereby lowering the drum on which the filter is mounted. The present invention relates to an industrial vacuum cleaner having an automatic filter structure for easily coupling and fixing and releasing collection tanks for collecting fine dust as well as easily mounting dust motors.

In general, the drum type vacuum cleaner includes a head 100 for sucking air and a drum body 200 for sucking and filtering fine dust including air.

The head 100 is provided with a cover 101, the cover 101 is provided in the housing 120 is provided with a blowing fan p for forcibly sucking air as a rotational drive of the motor portion in the cover 101 While being fixedly installed, the air outlet 121 is installed at one side of the housing 120 so as to discharge only pure air to the outside.

In the drum body 200, a collection bag for collecting garbage having a volume and specific gravity is installed at a lower portion of the drum body 200, and a filter 140 for filtering fine dust is installed at an upper portion thereof.

The collection bag is connected to the air suction port 121 side provided in the drum body 200, the suction pipe including the suction hose, the suction plate is connected from the air suction port 121 is installed to suck the fine dust containing garbage Since the description of the suction hose, the suction pipe and the suction plate is generally described below, the description of the reference numerals and the detailed description thereof will be omitted.

The filter 140 provided in the drum main body 200 is formed in a generally cylindrical shape, recessed recessed cylindrical portion with a predetermined width in a vertical direction on the bottom surface for the purpose of widening the filtration area of fine dust ( 141 is formed.

In addition, the upper end of the filter 140 is attached to the flange portion 142 for fixing over the upper portion of the drum body 200, the flange portion 142 is the head 100 located on the upper portion of the drum body 200 It is installed from the bottom of the edge of the side housing 120, the structure is fixed together with the cover 101 is closed is installed in the drum body 200 inside.

In general, the upper frame 150 is guided to match the inner diameter of the filter 140 and the outer shape of the recess cylindrical portion 141 in order to secure the maximum filtration area of the filter due to the strong air suction generated during vacuum cleaning. In addition, the upper frame 150 supports the filter in such a manner that the fixing string T passes through the filter 140.

In addition, a lower frame 160 supporting the recessed inner side of the recess cylindrical portion 141 including the bottom of the filter is positioned from the outside of the bottom of the filter 140 and the above-described upper frame 150, as described above. As such, the lower frame 160 and the filter 140 are configured to support the filter 140 as a fixing strap T.

A support ring 161 is integrally provided on the bottom of the lower frame 160, one end of the operation lever 170 is installed through the support ring 161, and the other end of the operation lever 170 is a drum body. Protruding to the outside of the 200 is configured to shake the lower frame 160 up and down.

The conventional vacuum cleaner configured as described above collects bulky general garbage in the collection bag as an air forced suction action of the blower fan (p), and at the same time, fine dust or the like passing through the collection bag is disposed on the filter ( Only pure air is filtered through 140, and the pure air is reduced to the outside through the air outlet 121 at the housing 120 in which the blowing fan p is installed.

The fine dust is collected in the drum body 200, and after a certain period of use of the vacuum cleaner to treat the fine dust filtered as a filter with the waste treatment in the collection bag.

On the other hand, in the above operation, the fine dust is attached to the outside of the filter 140 a considerable amount, depending on the degree of adhesion of the fine dust is not performed properly.

Accordingly, when the operation lever 170 is grasped by a hand and shakes up and down at the outside of the drum body 200, the lower frame 160 associated with the operation lever shakes up and down to move the attached movement to the outside of the filter. Fine dust and the like could be shaken off.

However, the movement of the lower frame 160 is limited to the upper and lower height relative to the upper frame 150, which has a disadvantage in that the fine dust is not easily shaken because the distance is relatively short.

As the fine dust is not easily shaken as described above, the filtration area of the fine dust is narrowed from the filter, as well as the filtration rate is very low, and there is a problem that causes an overload to the driven blower fan (p). This can degrade overall performance and ultimately cause vacuum cleaner failure.
