Title: Air gun with filter for moisture removal
Inventor: PARK JONG SIK
IPC: B05B12/00
Filed: 2021-03-19
Abstract: The present invention relates to an air gun equipped with a filter for removing moisture. More specifically, the present invention is to solve a problem in which compressed air injected into an air gun and an air hose which connects the compressor and the nipple of the air gun blowing compressed air through the nipple to the outside through the jetting hole by operating the opening and closing hole is not used for a long time or is liquefied according to the environment and sprayed like water through the nozzle. The compressed air provided in the air gun's internal supply pipe is not sprayed from the air gun's supply pipe to the nozzle, and the remaining compressed air passes through the inner inclined hole of the filter. When the compressed air containing moisture introduced from the air hose through the nipple is sprayed through the spray hole by the operation of the operating lever, moisture is removed while the compressed air passes through the inclined hole of the filter, and at the same time, the dispersion of moisture is facilitated through a net so that, when an operator uses the air gun, the compressed air containing moisture prepared inside the air hose and air gun passes through the inclined hole of the filter to remove moisture. It is possible to facilitate the dispersion of the moisture contained in the compressed air through the net to further remove the moisture in the filter.
