Problems solved by technology

Among them, the cyclone separation vacuum cleaner mainly uses the principle of centrifugal separation to strengthen the separation effect of dust (dust) and has been widely cited. However, the current cyclone separation vacuum cleaner, due to the attenuation of the airflow process, Often cannot fully achieve the effect of centrifugal separation, which will easily lead to poor actual dust separation effect

Abstract

The invention discloses an inwardly double inlet-type multistage separation type dust collector. The dust collector comprises a housing, a dust cup and a dust collection motor. The dust cup comprisesa cup body, a cup cover and a bottom cover. A first air inlet and a first air outlet are arranged in the dust cup. The inside of the cup body is equipped with a filter cylinder and a second-stage separator. The second-stage separator separates the cup cover from the cup body. The second-stage separator comprises multiple cyclone separation cones. Lower end openings of the cyclone separation conesare less than the opening diameter of the upper end. The side wall of each cyclone separation cone is equipped with two tangential air supply pipes located in the interior of the cup cover. The lowerend of each cyclone separation cone communicates with the interior of the filter cylinder. The upper end of each cyclone separation cone communicates with the interior of the cup cover. The housing isequipped with a primary suction opening and a main discharge opening. The inwardly double inlet-type multistage separation type dust collector has the following beneficial effects: air flows can be dispersed in order to increase relative flow speed of each dispersion air flow; additionally, by increasing relative air inlet amount, centrifugal separation effect is enhanced; the final separation effect of dust is improved; and the dust collection capability is strong.

Description

technical field [0001] The invention belongs to the technical field of vacuum cleaners, in particular to an inner double-inlet multi-stage separation vacuum cleaner. Background technique [0002] The vacuum cleaner is a common electrical appliance. The working principle of the vacuum cleaner is: use the vacuum motor to generate negative air pressure in the sealed casing to absorb dust. There are many types of vacuum cleaners, which can be divided into vertical, horizontal and portable according to the structure, and can be divided into cyclone separation type, dust bag separation type, electrostatic precipitator type, etc. according to the separation method. Among them, the cyclone separation vacuum cleaner mainly uses the principle of centrifugal separation to strengthen the separation effect of dust (dust) and has been widely cited. However, the current cyclone separation vacuum cleaner, due to the attenuation of the airflow process, Often the effect of centrifugal separa...
