BAG FILTER FOR VACUUM CLEANER WITH CLOSURE DEVICE AND VACUUM CLEANER TO POST SPECIFIED FILTER Russian patent published in 2010 - IPC A47L9/14 

FIELD: personal use articles.

SUBSTANCE: bag filter is designed for a vacuum cleaner. Bag filter includes an inlet hole, a retention plate located outside the bag filter near the inlet with the possibility of acceding to the vacuum cleaner restraint to fix the bag filter, and the closing device, which is located near the inlet of the bag filter and is designed so that before installing the bag filter in the vacuum cleaner, it takes the first position, and after the bag filter installing inside the vacuum cleaner it can be transmitted into the second position. Inlet of the bag filter is closed when the shut-off device is in the first position and open when the closure device is in the second position. The closing device in the second position comprises two trapezoidal or rectangular covering surfaces, which, starting from the inlet of the bag filter, in a wedge-shaped mode converge to each other forming a connecting edge opposite the inlet of bag filter, or parallelepiped shape, which includes the first side surface surrounding the inlet hole of the bag filter connected to the inner side of the said filter and having an inlet, and at least one more side surface, adjacent to the first side surface and having an outlet. The vacuum cleaner for placing the specified bag filter comprises a body with a restraint placed in it, designed to connect to the holding plate of the bag filter, and placed in the said body so that the bag filter closing device for a vacuum cleaner when connected to the retention plate to the restraint takes the second position. The vacuum cleaner has a holding device for a holding plate of the bag filter, which includes the closing device placed inside a bag filter in the area of its inlet and made in such a way that when a shut-off device is in the first position the inlet is closed, and when the shut-off device is in the second position when the shut-off device has a parallelepiped shape, the inlet is open, and the opening device made in such a way that when the shut-off device is in the first position it may take the first position, and in transition of the opening device to the second position the said opening device can communicate with the closing device and transmit it to the second position.

EFFECT: ensuring simplicity and reliability of the closing device.
