Pressurized air-filter container for mounting on a laser engraver

Abstract

A pressurized air-filter container for mounting on a laser engraver, the structure includes a body container, an electric fan and at least a lens stand disposed within the body container for that a lens can be mounted thereon. An air inlet and air outlet is each located on lateral sides of the body container. An electric fan mounted on top of the air outlet draws air into the body container and, subsequently exhales air out through its other end to prevent exterior dust particles from accumulating on the lens surface.

1 . A pressurized air-filter container for mounting on a laser engraver, comprising: 
 a body container, having at least one lens stand disposed therewithin for mounting a lens, and having an air inlet and air outlet each located on lateral sides thereof; and    an electric fan, mounted around the air inlet, wherein air is drawn into the body container, and subsequently exhales out through the air outlet to prevent exterior dust particles from entering the body container and being accumulated on the lens.    
   
   
       2 . The pressurized air-filter container as claimed in  claim 1 , wherein the fan further includes a filter material used to filter the drawn-in air.  
   
   
       3 . The pressurized air-filter container as claimed in  claim 2 , wherein the filter material may be an air-filter cloth or air-filter body  
   
   
       4 . The pressurized air-filter container as claimed in  claim 1 , wherein the body container is in the form of an L, and the air inlet is located at a lateral side of lower portion of the body container, while the air outlet is located on the top of the body container.
