However, the existing cleaning device is not easy to access to the ship building workshop or the corresponding block of the workshop, and in the case of the block installation of power supply, the cleaning quality and the work efficiency are deteriorated because the cleaning is performed using a broom and a dustpan. .

Therefore, the present field requires the development of a small vacuum cleaner using air that is easy to use outside and inside the block, and the same situation requires the development of a small dust collector using air in a closed area where it is difficult to install the dust collector.

For example, there is an urgent need for dry and wet cleaners that can collect welding sludge, fly-by-flours, residual water (remaining water), and fine dusts associated with painting operations. Are unable to meet the above working and cleaning conditions.

As a prior art of the present invention, a compressed air-operated dust vacuum recovery device is disclosed as a patent document, but a purging function for carrying out filter cleaning by itself is inconvenient to access and use the block by a large-sized moving trolley. It is absent, there is a disadvantage that can not be used to select the cleaning function and purging function according to the working conditions.

In addition, the air ejector of the patent literature generates only the suction force for dust collection, so that the collected foreign matter (such as iron powder or scrap metal) penetrates the filter and is immediately discharged to the outside through the air ejector, which damages the worker. It has a disadvantage that a safety accident can occur.

In addition, the apparatus of the patent document is generating excessive noise by the air exiting the air ejector, in particular, when using a plurality of air ejectors to improve the operation efficiency, excessive noise is generated as a vibration noise to the user Has the disadvantage of providing excessive discomfort due to.
