Abstract

The invention discloses a knapsack type dust collector. A knapsack device is formed by fixing a waist belt and shoulder belts on a backing plate through tying belts; the backing plate is an integral formed by fastening an rabbet on the backing plate and a groove on the upper end of a large cylinder; a dust collecting device is formed by the matching of a paper filter bag and an advanced filter fixed on a motor cavity, wherein the paper filter bag is connected with an air inlet pipe and placed into a bag dust filter; and a strap joint is an integral formed by fixing a transparent cover connected with the air inlet pipe and a cover connected with a warped switch. The knapsack type dust collector has a filtering ratio up to 99.90 percent, and is particularly suitable for hospital, laboratories and other places special cleaning requirements. The invention can be conveniently put on the shoulders, is labor-saving and convenient, is more convenient for long-time operation, is particularly suitable for working in narrow spaces on planes, high-speed railway locomotives, deluxe coaches and other transportation vehicles, and reduces labor intensity. Moreover, dust can be observed directly through the transparent cover, which is convenient for real-time processing and avoids secondary pollution, and the strap joint is connected with the dust collecting pipe and a dust collecting head through a connection pipe capable of rotating omnidirectionally, thereby avoiding pipe-winding phenomenon.
