Dust collector with simple structure, reliability, durability and high cost performance

Abstract

The invention relates to a dust collector with simple structure, reliability, durability and high cost performance. Along with the constant development of a motor technology, on the premise of same air amount and vacuum degree, the volume of a motor of the dust collector is diminished increasingly, and the weight of the motor is lightened increasingly, thereby providing development space for the dust collector. The dust collector with a new structure provided in the invention not only can be used as a push-rod type dust collector for cleaning floors, roofs and walls and removing an engine body, but also can be used as a handheld dust collector for cleaning sofas, the surfaces of electric appliances, corners and the like. The dust collector has fewer parts, is simple in structure, and simple and convenient to operate, has small volume and low cost, meets basic requirements of large air flow and dust capacity, and being capable of adapting to various universal accessories of a common dust collector, is characterized by being low in noise, and has obvious market advantage.

Description

Technical field: [0001] The present invention relates to household and commercial vacuum cleaners, especially combined small upright vacuum cleaners. Background technique: [0002] The vacuum cleaner uses a vacuum fan as the power source, which can generate a certain degree of vacuum and air volume. By connecting with various specially designed floor brushes, brushes, and suction ports, it can effectively remove various dust in the home environment. Vacuum cleaners have been around for nearly 100 years. In Europe, America and other countries, vacuum cleaners are a special cleaning tool for removing dust and are indispensable in family life. The annual market sales of vacuum cleaners exceed 130 million units. [0003] The mainstream form of existing vacuum cleaners is horizontal vacuum cleaners (see attached figure 1 ), including a fan that can generate vacuum, connected to the ground brush through hoses, long connecting pipes and other components. However, this form of vac...

AI Technical Summary

Problems solved by technology

However, this form of vacuum cleaner has two obvious defects: one is that there are too many parts, the operation is cumbersome and locks, and a large storage space is required; the other is that the operation is hindered by furniture, and it is inconvenient to drag during use

There is an obvious defect in this combined vacuum cleaner—limited by the space of the body, the dust capacity is small. When cleaning the ground, the dust on the ground will quickly block the air duct, resulting in a rapid drop in suction.

Therefore, this combined vacuum cleaner has insufficient ground cleaning function, and cannot compete with mainstream horizontal vacuum cleaners or vertical vacuum cleaners. In actual use, it can only be used as a supplement to mainstream vacuum cleaners.
