A dust collection system for portable sanding or grinding equipment employs a cyclone separator mounted directly on the tool or machine, with a dust outlet duct at the narrow lower end of the cyclone, and a cartridge air filter mounted on the top of the cyclone. The filter returns the air flow from the machine to the ambient air in the vicinity of the tool. The dust is concentrated in the cyclone, and a small volume air flow then moves the dust through an elongated flexible hose or duct to a remote dust collection station. An air pump at the remote dust collection station provides sufficient air flow to draw the small volume of air plus entrained dust from the tool-mounted cyclonic separator. A cyclonic separator at the remote station separates this dust from the air flow and deposits it in a collection tank or drum.

A blade assembly of an autonomous cleaning device. The blade assembly includes a blade having a first part fixed to the main body and a second part extended from the first part toward a floor and a support member having at least a portion disposed adjacent to the second part of the blade to restrict movement of the second part of the blade to within a predetermined range.

It is provided in the present invention with a pervasive dedusting device for a vacuum cleaner, which includes a tank with a wind inlet and a wind outlet. A filter barrel is mounted inside the tank while a cyclone barrel is mounted inside the filter barrel. The cyclone barrel is configured to be a conical barrel with a smaller upper end and a larger lower end and a cyclone wind inlet is disposed on it. The wind inlet on the tank and the cyclone wind inlet on the cyclone barrel are separated by the filter barrel and located in two chambers respectively. A wind outlet tube is located in the upper end of the cyclone barrel and communicates with the wind outlet. The pervasive dedusting device has low air flow pressure loss, improved dust suction effect, fine dust filtering function, decreased operation noise, and it can effectively prevents secondary pollution and filter out fine dust completely.

The invention discloses a vacuum sweeper sucker structure with the automatic avoiding function. The vacuum sweeper sucker structure with the automatic avoiding function comprises a main sucker and two auxiliary suckers. The two auxiliary suckers are rotationally installed on the two sides of the main sucker respectively. The main sucker and the auxiliary suckers are all of a shell structure with an opening in the lower end. The top of the main sucker and the tops of the auxiliary suckers are all provided with dust suction pipes communicated with the interior of a shell. A rotating element is clamped to the top of the end, close to the main sucker, of each auxiliary sucker. The rotating elements are rotationally installed on the main sucker. Two driving mechanisms corresponding to the rotating elements one to one are symmetrically arranged on the top of the main sucker. The driving ends of the driving mechanisms are connected with the corresponding rotating elements. Elastic resetting devices are arranged on the auxiliary suckers. One end of each elastic resetting device is fixed to the corresponding auxiliary sucker, and the other end of each elastic resetting device is connected with the corresponding rotating element. The vacuum sweeper sucker structure with the automatic avoiding function is simple in structure, convenient to use and large in dust suction range, automatic avoiding can be performed after the vacuum sweeper sucker structure collides with a barrier, it is avoided that the suckers are damaged by external force, the structure is flexible, and practicability is high.
