Description

Technical Field

[0001] The utility model relates to a vacuum cleaner structure with a rotation switching function of air suction and air blowing, belonging to the technical field of vacuum cleaner products. Background Art

[0002] A vacuum cleaner is a commonly used cleaning device that can be used at home as well as in offices and production environments to absorb dust and small debris in indoor environments. Currently, the main function of vacuum cleaners on the market is to absorb dust and have an air suction function. They cannot meet the use requirements when blowing or air is needed. For example, the air blowing function is used to blow away some debris, such as dust in the gaps of keyboards, and clean by blowing out clean air. A small number of vacuum cleaners with a blowing function have a more complicated structure, high cost and price, and some do not blow out clean air. The air blown out is dirty when it passes through the vacuum cleaner HEPA and cannot be used to clean the external environment.

[0003] Patent No. 922409021 discloses a multifunctional blowing and suction vacuum cleaner, which is provided with a blowing device 18, an inner dust suction pipe 11 is sleeved in the dust suction pipe 8, and the blowing port 14 of the blowing device 18 is connected to the inner dust suction pipe 11 through a conduit so that a strong airflow is blown out from the dust blowing nozzle 17 in the dust suction head 10 to blow up dust and debris, and then the dust and debris are sucked into the dust storage chamber 12 from the channel between the dust suction pipe 8 and the inner dust suction pipe 11 by negative pressure, and the air filtered by the filter screen 5 enters the blowing chamber 13 to form an air circulation loop. The vacuum cleaner is suitable for a variety of occasions, has a high degree of cleanliness, and does not produce secondary dust pollution. The dust storage chamber 12 can be used as a blowing device after being removed. However, when the vacuum cleaner uses the blowing function, the dust storage chamber 12 needs to be removed, and the suction and blowing functions cannot be quickly adjusted and switched, which is inconvenient to use.
