Pure suction vacuum cleaner

Abstract

The present invention proposes a pure suction vacuum vehicle, which includes a vehicle frame, a vehicle power transmission system is provided below the vehicle frame, a filter box main body is provided above the vehicle frame, and a suction cup is provided at the lower part of the filter box main body device, the suction cup device includes a dust suction rack, a detachable dust suction pipe and a first-stage filter blowing pipe arranged on the dust suction rack, and a three-stage filter system and a filter back-blowing device are arranged in the main body of the filter box. The end of the main body of the filter box away from the suction cup device is provided with a fan, and the three-stage filter system is sequentially provided with a coarse filter device, a fine filter device and a water mist purification device along the direction of the air intake of the dust suction pipe. It includes a fan arranged on the main body of the filter box and a filter element cleaning air duct arranged in the main body of the filter box. The present invention is equipped with a three-stage filter system and a filter screen blowback device in the filter box, which not only has a simple structure and good dust collection effect, but also is environmentally friendly, energy-saving, time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the field of sanitation vacuum cleaners, in particular to a pure suction vacuum cleaner. Background technique [0002] With the continuous development of the country and the continuous progress of the society, our requirements for the environment far exceed the previous requirements. Large-scale cleaning sites such as urban sanitation, ports, highways, coal mines and cement plants, etc., are time-consuming and labor-intensive if they are cleaned manually. In order to solve the above problems, a sweeper was born. For example, in the northern region, it is cold in winter and water cannot be sprinkled. The dust is flying when the sweeper is working, causing secondary pollution to the atmosphere. When the sweeper is cleaning, the brushes are severely worn, replaced frequently, and the manual workload is large. A series of problems, now the sweeper is gradually being replaced by a pure suction vacuum cleaner. [0003] The design a...
