Knapsack type dust collector

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.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a backpack type vacuum cleaner which can be carried on the shoulder and used to deal with dust in a narrow space or used in hospitals and laboratories with special cleanliness requirements. Background technique [0002] With the development of scientific and technological transportation and the improvement of people's living standards, the current means of transportation have also been upgraded. Airplanes, EMUs, and high-speed railways have been widely used as means of transportation for people to travel. These high-speed and convenient means of transportation are coming one after another. The cleaning and sanitation work must also keep up with, and must be able to meet the needs of high speed and fast pace, but the existing vacuum cleaners are mostly vertical, horizontal, portable, walking, portable, and some have small power and some are bulky. Large, some are inconvenient to move and carry,...

[0002] With the development of scientific and technological transportation and the improvement of people's living standards, the current means of transportation have also been upgraded. Airplanes, EMUs, and high-speed railways have been widely used as means of transportation for people to travel. These high-speed and convenient means of transportation are coming one after another. The cleaning and sanitation work must also keep up with, and must be able to meet the needs of high speed and fast pace, but the existing vacuum cleaners are mostly vertical, horizontal, portable, walking, portable, and some have small power and some are bulky. Large, some are inconvenient to move and carry, and some are not suitable for working in narrow spaces and places with special cleanliness requirements such as hospitals, which have great limitations

[0003] Patent No. 200830221781.2 "Backpack Vacuum Cleaner", although it also provides a backpack vacuum cleaner, it can only be seen from the outline drawing that the back panel of this vacuum cleaner is inserted into the brackets connected to the two sides of the vacuum cleaner body, which is not only large in size, but also Moreover, the back panel is uncomfortable to use, and it is also impossible to observe the accumulation of dust inside the vacuum cleaner.
