Patent number: 8302253Abstract: A cyclone separation dust cup, which includes a cup body and a cyclone tube, the cyclone tube being provided with an air inlet, an ash ejection outlet, and an air exhaust outlet; and the ash ejection outlet communicates with a dust storage cavity in the cup body, the air exhaust outlet with an air outlet positioned on the cup body through an air exhaust pipe, and the dust storage cavity with the air exhaust pipe. The dust storage cavity, by communicating with the air exhaust pipe, enables part of the air current entering the cyclone tube to enter the dust storage cavity in the cup body, thus producing suction in the ash ejection outlet of the cyclone tube that can draw the dust into the dust storage cavity. This enables the impurities with a lighter weight (e.g. hair and downy floc), which cannot fall into the dust storage cavity under gravity, to be inhaled into the dust storage cavity successfully, thus greatly improving the separating and filtering effect of this cyclone separation dust cup.Type: GrantFiled: March 31, 2010Date of Patent: November 6, 2012Assignee: Suzhou Kingclean Floorcare Co., Ltd.Inventor: Zugen Ni

Patent number: 7563296Abstract: 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.Type: GrantFiled: April 5, 2006Date of Patent: July 21, 2009Assignee: Suzhou Kingclean Floorcare Co., Ltd.Inventor: Zugen Ni

Patent number: 7225504Abstract: A noise suppressor for use with the vacuum air cleaner includes an enclosed casing. On the casing, there are an air intake end and an air outlet end. Between the air intake end and the air outlet end, there is the noise suppressing chamber. At the air intake end and the air outlet end, there are the air intake area and the air outlet area made up of densely arranged dust-shaped air exhaust microholes. The air intake sectional area and air outlet sectional area, which are defined by the cross-sectional area of the microholes respectively, are smaller than the sectional area of the noise suppressing chamber. A number of noise suppressing structures or arrangements may be used to form the noise suppressor. After being installed at the air exhaust port of the vacuum air cleaner, the noise suppressor can greatly reduce the noise the vacuum air cleaner gives out when in use.Type: GrantFiled: April 10, 2003Date of Patent: June 5, 2007Assignee: Suzhou Kingclean Floorcare Co., Ltd.Inventor: Zugen Ni
