Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] see figure 1 and figure 2 , a cyclone-separated dust cup, comprising a cylindrical cup body 1 and a matching dust cup cover (not shown) arranged above the cup body 1, a filter 2 is arranged between the cup body 1 and the dust cup cover, The side wall of the cup body 1 is provided with a primary air inlet 11 for tangential air intake, and the dust cup cover is provided with an air outlet. A cup bottom cover 5 is arranged below the cup body 1 .
[0018] The dust cup of the present invention is a two-stage separation type, wherein the dust cup 1 is provided with a cylindrical cyclone separator 31, which forms a primary separator located upstream with the side wall of the dust cup 1, and the inside of the bottom cover 5 of the cup forms a The primary dust storage chamber 32. A dust collection barrel 4 is arranged below the cyclone sepa...

The invention discloses a cyclone separation type dust cup which comprises a cup body and a cyclone separation system arranged in the cup body, wherein the side wall of the cup body is provided with a tangential primary air inlet; the cyclone separation system comprises an upstream primary separator, a downstream secondary separator and an airflow channel formed between the two separators; the primary separator comprises a cylindrical cyclone separation body and a primary dust storage cavity positioned below the cyclone separation body; the secondary separator comprises multiple inverted conical cyclone separation cores positioned in the upper part of the cyclone separation body and a secondary dust storage cavity positioned below the cyclone separation cores; the upper ends of the cyclone separation cores are provided with secondary air inlets communicated with the airflow channel; the upper parts of the cyclone separation cores are internally provided with spiral pipes which are used for changing the directions of airflow entering from the secondary air inlets to be tangential with the side walls of the cyclone separation cores. By virtue of the spiral pipes arranged at the corresponding parts of the secondary air inlets, the directions of the airflow entering the spiral pipes are compulsively changed so as to be tangential with the side walls of the cyclone separation cores all the time, and the air and dust separation effect is improved.
Description
technical field [0001] The invention relates to a dust cup of a vacuum cleaner, in particular to a cyclone-separated dust cup. Background technique [0002] The dust cup used for filtering is the main part of the vacuum cleaner. In order to better separate impurities such as dust from the air, most existing vacuum cleaners use a cyclone dust cup for secondary separation. The air containing impurities enters the first-stage separator along the tangential direction, and makes a rotary motion from top to bottom. During the rotary process, large particles and heavier impurities collide with the first stage due to their greater density than air and greater centrifugal force. The inner wall of the separator loses its inertia and falls into the dust collecting chamber below to be separated from the air. The finer impurities and air enter the second-stage separator, and the fine dust collides with the inner wall of the second-stage separator and loses inertia and falls into the dus...
