Problems solved by technology

However, because this technology places a separator in the limited inner cavity of the dust cup, the separation effect is not ideal.
Furthermore, the first separation of the dust cup and the second separation are in the same cavity, and it is inevitable that a small amount of unseparated air directly enters the air inlet of the second separation with the air flow, causing the workload of the second separation Increase

Embodiment Construction

[0019] figure 1 , figure 2 , image 3 , Figure 4 It is a vacuum cleaner dust cup for secondary separation in the present invention. The dust cup of the vacuum cleaner includes a dust cup housing 2 , an air inlet 3 and an air outlet 1 . The separator placed in the housing 2. The separator includes a cylindrical body 9 standing upright on the bottom cover 12, the outer wall of the cylindrical body is provided with an isolation cover 7, and the inner wall is connected with a conical tube 8 with both ends opened and constricted downwards. A tangential air inlet 4 is arranged on the circumferential wall at the upper end of the tube, and the air inlet is formed by a plurality of helical blades arranged uniformly in a helical rotation. The top of the spiral blade is connected with the top of the housing. An annular cover 6 is arranged on the periphery of the spiral blade, and an annular gap is formed between the annular cover and the upper straight pipe, thereby forming an an...

Abstract

A dust cup unit with multiple separations for cyclone cleaner is composed of shell, air inlet, air outlet, and parallel two separators, which consists of a barrel body vertical to bottom cover, an isolating cover connected to external surface of said barrel body, a conic body with two open ends connected to internal surface of said barrel, a straight tube connected to upper part of said conic body and with a tangent air inlet formed by multiple spiral blades, and an air outlet tube with two air inlet branch tubes arranged in the center of said two separators. The separations of coarse dust and fine dust are performed respectively in two spaces.

Description

technical field [0001] The invention relates to a vacuum cleaner accessory, in particular to a vacuum cleaner dust cup device for separating dust and air of a centrifugal vacuum cleaner. Background technique [0002] The dust cup of the vacuum cleaner is a key component of the vacuum cleaner. The quality and performance of the dust cup are directly related to the quality and life of the vacuum cleaner. With the continuous innovation of vacuum cleaner manufacturing technology, various dust cups for secondary and tertiary efficient separation of air and dust have come out one after another. The application number applied by me is "200610052582.3", "A Secondary Cyclone Separation Dust Cup for Vacuum Cleaner" is a dust cup product with better separation effect. The air is separated again, which greatly reduces the accumulation of fine dust brought out by the air outlet with the airflow on the filter at the inlet of the electric fan. Compared with the dust cup that only separate...
