A direct filter dust collection device

Abstract

The invention discloses a direct filtration type dust collection apparatus which comprises a main machine housing, a dust collection motor and an isolation plate. A filtration bag is arranged in a filtration cavity and comprises a bag frame and a bag body, a dust inlet opening communicated with the inside of the bag body is formed in the bag frame, the bag frame is in clamped connection with a suction opening seat, the dust inlet opening is communicated with a main air inlet, and a plurality of hook rings fixed to the bag body are arranged on the outer side surface of the bag body. Multiple shape-keeping pull ropes for lifting and pulling a dust filtering bag are arranged in the filtration cavity, a connector is arranged at one end of each shape-keeping pull rope, the other end of the shape-keeping pull rope is connected with the main machine housing, the connectors correspond to the hook rings in a one-to-one mode and are connected with the corresponding hook rings, and the lowest point of any shape-keeping pull rope is higher than the lowest point of the dust filtering bag. The direct filtration type dust collection apparatus has the advantages that the structure is reasonable, the dust filtering bag can be protected and kept in shape, the closeup of the dust filtering bag is effectively avoided, the filtering efficiency and a cleaning effect can be ensured, the utilizing efficiency of the dust filtering bag is high, the cost can be reduced, and environmental protection property is good.

Description

technical field [0001] The invention belongs to the technical field of vacuum cleaners, and in particular relates to a direct filter type dust collection device. Background technique [0002] With the development of the times and the improvement of living standards, vacuum cleaners, especially household vacuum cleaners, have been widely used. A vacuum cleaner is an electrical appliance that uses an electric motor (dust collection motor) to generate negative air pressure in a sealed housing to suck in dust or garbage. Dust bag vacuum cleaner is a type of vacuum cleaner. It also uses a dust collection motor to suck air, and uses a filter dust bag to filter, trap garbage, impurities, and dust, and finally discharge the filtered air to the outside world through the dust collection motor. . However, in the current bag-type vacuum cleaner, after the intercepted matter in the filter bag increases and becomes heavier, the filter bag will be in a "elongated" state, resulting in ins...
