Dust collector, dust cup device and multi-conic cyclone assembly

Abstract

The invention provides a multi-conic cyclone assembly. The multi-conic cyclone assembly comprises a multi-conic body, a cyclone tube and multiple spoilers; the multi-conic body comprises a conic body of which the section is shaped like a cone and multiple cone-shaped inner cavities formed in the conic body, a dust inlet is formed in the inner wall of one end of each cone-shaped inner cavity, and the other end of each cone-shaped inner cavity is provided with a dust outlet; the cyclone tube comprises an end cover and multiple air outlet pipes, the end cover is installed on the multi-conic body, and each air outlet pipe is arranged at the corresponding dust inlet in a penetrating mode and located in the corresponding cone-shaped inner cavity; the spoilers are installed in the air outlet pipes respectively. When a dust collector works, an air flow enters the multi-conic body through the dust inlets to form a cyclone, dust is pushed by the centrifugal force produced by the cyclone along the cone-shaped inner cavities, the spoilers can play the spoiler role in the air outlet pipes, the cyclone is disordered or disappear, the cyclone is prevented from pushing the dust to the direction of the air outlet pipes, the filtering capacity is improved, and the property of the dust collector is improved. The invention further provides the dust collector and a dust cup device thereof.

Description

technical field [0001] The invention relates to the technical field of dust collection equipment, in particular to a vacuum cleaner, a dust cup device and a multi-cone cyclone assembly thereof. Background technique [0002] The dust cup vacuum cleaner separates an airflow into multiple small airflows through the cyclone technology, and separates the dust from the airflow through centrifugal force, avoiding the clogging of the traditional dust bag, and the unobstructed airflow ensures large and long-lasting suction. In the current technology, there is a cyclone with a baffle. This cyclone adds a structure of a baffle to the ash outlet of the multi-cone. This structure can prevent repeated separation caused by the backflow of accumulated ash to the multi-cone. low separation efficiency. However, this structure also has disadvantages. It can only prevent the accumulated dust from flowing back into the multi-cone, but it cannot guarantee that the dust inhaled from the outside c...
