Description
Technical Field
The invention relates to the technical field of dust collectors, in particular to a high-efficiency dust collecting head and a dust collector.
Background
Along with people's standard of living is better and better, the dust catcher becomes the family and cleans the indispensable burnisher of health time, alleviates people's intensity of cleaning, and labour saving and time saving also needs to use the dust catcher to clean factory building, machine equipment etc. usually in the workshop of mill. At present, the types of dust collectors are various, and the dust collectors can be divided into vertical type, horizontal type and portable type according to structures. The dust collector mainly comprises three parts of dust generation, dust collection and dust filtration, and generally comprises a series excitation commutator motor, a centrifugal fan, a dust filter (bag) and dust collection accessories. The working principle of the dust collector is that a wind impeller is arranged on a rotating shaft of an exhaust fan, after the wind impeller is electrified, the wind impeller is driven to rotate by the wind impeller at the rotating speed of 500 circles per second, high suction and pressure are generated in a sealed shell, air is discharged at high speed under the action of the suction and the pressure, air in a dust collection part at the front end of the fan continuously supplements air in the fan, instantaneous vacuum is generated inside the dust collector, negative pressure difference is formed between the air and the external atmospheric pressure, and air containing dust is sucked under the action of the pressure difference. The dust and dirt in the suction nozzle are sucked into the dust suction part along with the air and are leaked through the leakage device to be collected in the dust cylinder.
Generally, in order to improve the cleaning effect of the vacuum cleaner, some cleaning devices are arranged on the suction nozzle, for example, the utility model with the publication number of CN211270487U discloses a household vertical vacuum cleaner, the absorption device of the vacuum cleaner comprises a base, bayonets on two sides of the bottom surface of the base are connected with brushes, and the brushes can further play a role in cleaning and disturbing dust in the cleaning process. For example, the utility model with publication number CN210277052U discloses a household vacuum cleaner, the bottom of the vacuum cleaner head of which is fixedly provided with a floor mopping device to improve the cleaning ability. However, the above-mentioned vacuum cleaner has the following disadvantages:
1. in the cleaning process of the dust collector, the dust at the part to be cleaned is adsorbed by moving the dust collection head of the dust collector 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 at the part to be cleaned (such as a floor) so as to improve the cleaning capability; however, some of the dust or dirt adhered to the object to be cleaned, which has a strong viscosity, is difficult to be sucked into the cleaner, and thus a good cleaning effect cannot be achieved.
2. In some wooden floor of assembling or ceramic tile, or in the machine equipment, the gap between plank and the plank, the gap between ceramic tile and the gap between ceramic tile, the gap between the machine equipment component, the dust of very easy storage, adopt current dust catcher, it is difficult to carry out the disturbance with the dust in the gap, do not reach a fine cleaning performance.
Disclosure of Invention
The invention aims to overcome the problems and provide a high-efficiency dust collection head, which can not only clean garbage or dust which has strong viscosity and is attached to an object to be cleaned, but also suck the dust in gaps on the object to be cleaned into a dust collector, thereby greatly improving the cleaning effect.

Example 4
Referring to fig. 16, the other structure of this embodiment is the same as that of embodiment 1, except that 2 of the 4 sets of rotary cleaning devices are disposed in parallel to each other on one side of the suction cup, the other 2 sets are disposed in parallel to each other on the other side of the suction cup, and the axes of the roller type brushes of the rotary cleaning devices on both sides are disposed perpendicular to each other.
Example 5
The other structure in this embodiment is the same as that in embodiment 1, except that the number of the gas nozzles 2-1 may be 3 or more than 3, and the gas nozzles 2-1 may be distributed around the chuck 1 or in other shapes, such as "i" shape or grid shape.
Example 6
The other structure in this embodiment is the same as that in embodiment 1, except that the power source of the cleaning driving mechanism in this embodiment may be an independent continuous positive pressure gas supplier, and the impeller 3-3 can be continuously rotated by blowing continuous positive pressure gas into the cylinder 3-2, so as to drive the brush 3-1 to rotate.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
