Dust collecting apparatus of vacuum cleaner

Abstract

The invention discloses a dust-collection device of vacuum dust collector comprising: a dust-collection barrel for collecting the foreign matters in the air; a upper cover arranged on one side of dust-collection barrel for switching the dust-collection barrel; a filter element assembly which is detachable and filters the foreign matters; a exhaustion tube arranged under the filter element assembly to exhaust the filtered air outside the dust-collection barrel; a air exhaustion part formed on the end of exhaustion tube and depressed to the dust-collection barrel which comprises a air exit hole, a pressure-connected surface and a pressure-collected swing, wherein, the air exit hole is through to the exhaustion tube; the pressure-connected surface is connected to the exhaustion sealing surface of dust-collection barrel and the pressure-connected swing is projected formed on one side of pressure-connected surface. The invention comprises following advantages that the inventive pressure-connected swing can improve the sealing property and the air leak-proof property of exhaustion sealing element of dust-collection barrel, to reduce the loss of suction generated by the motor, and improve the property of vacuum dust collector and meet the demand of users.

Description

Technical field [0001] The present invention relates to a vacuum cleaner, and particularly relates to a dust collecting device of the vacuum cleaner. Background technique [0002] figure 1 It is a schematic diagram of the appearance of an existing vertical vacuum cleaner. [0003] As shown in the figure, the vertical vacuum cleaner includes a nozzle assembly 60; a body 70; and an operating handle 72. The suction nozzle assembly 60 moves back and forth on the ground and sucks in foreign objects such as dust. The body 70 is provided with a suction device for generating suction. The operating handle 72 is arranged on the upper part of the main body 70, and the user can grasp the operating handle for cleaning. [0004] The suction nozzle assembly 60 sucks dust-laden air through a suction port (not shown in the figure) formed on the bottom surface. The outside of the nozzle assembly 60 is composed of upper and lower nozzle upper covers 60" and a lower nozzle cover 60'. The lower par...

Problems solved by technology

That is, although the crimping surface 24 of the exhaust portion 20 and the dust bucket exhaust seal 80 are combined in surface contact, they cannot be effectively sealed, and then air leakage occurs.

Due to the leakage of air, the suction force inside the body 70 will be reduced, and the cleaning ability of the vacuum cleaner will be reduced at the same time
