Description

Dust collection head with scraping function and dust collector

Technical Field

The utility model relates to the technical field of dust collectors, in particular to a dust collection head with a scraping function and a dust collector.

Background

Along with the better living standard of people, the dust collector becomes an indispensable cleaning tool when the family cleans the health, lightens the cleaning intensity of people, and saves time and labor. Currently, dust collectors are various in variety, and can be classified into vertical, horizontal and portable according to structures. The dust collector mainly comprises three parts of dust generation, dust collection and dust filtration, and generally comprises a series excited rectifier motor, a centrifugal fan, a dust filter (bag) and a dust collection accessory. The working principle of the dust collector is that a fan blade wheel is arranged on a rotating shaft of an exhaust fan, after the dust collector is electrified, the exhaust fan can drive the fan blade wheel to rotate at a rotating speed of 500 circles per second, high suction force and high pressure are generated in a sealed shell, air is discharged at high speed under the action of the suction force and the pressure, air in the fan is continuously supplemented by air in a dust collection part at the front end of the fan, so that instantaneous vacuum is generated in the dust collector, a negative pressure difference is formed between the air and the external atmospheric pressure, and the air containing dust is sucked under the action of the negative pressure difference. Dust and dirt of the suction nozzle are sucked into the dust suction part along with air and are leaked through the leakage device, and the dust and dirt are collected in the dust barrel.

In general, in order to improve the cleaning effect of the cleaner, a cleaning device is provided on the suction nozzle, for example, the utility model patent with the publication number CN211270487U discloses a household upright cleaner, the suction device of the cleaner comprises a base, two side bayonet openings on the bottom surface of the base are connected with brushes, and the brushes can further play a role in cleaning and disturbing dust during the cleaning process. For example, patent publication No. CN210277052U discloses a household cleaner having a floor cleaning device fixedly mounted to the bottom of the cleaning head to enhance cleaning ability. However, the above-described vacuum cleaner has the following disadvantages:

1. in the cleaning process of the dust collector, dust on the ground is adsorbed by the dust collection head of the dust collector which moves back and forth, and in the back and forth moving process, the brush or the floor mopping device of the dust collector can disturb and wipe the dust on the floor so as to improve the cleaning capability; however, some of the dust or dirt adhering to the floor, which is strongly adhered to the floor, is difficult to be sucked into the cleaner, and thus a good cleaning effect is not achieved.
