Cyclone separator of vacuum cleaner

Abstract

The invention discloses a cyclone separator, which comprises the following parts: cylinder, tangent inlet on upper end of cylinder, cylinder roof in connection with rack, short outlet pipe in connection with rack bottom hole in the center of cylinder, concial cylinder in the inner wall of cylinder with lower position than short pipe, dust collecting cavity between concial cylinder bottom and bottom lid, wherein the bottom of concial cylinder possesses baffle bag, whose peripherial wall connects outer wall of concial cylinder through connecting bar; one ring-shaped gap is formed between inner wall of separating bag and outer wall of concial cylinder; the separator is paralleled by multiple individual separators; multiple housing separators are set around separator in the inner wall of dust cup; each short outlet pipe of separator connects rack bottom hole; the separator inlet is set on the bottom lid of separator, which is between ring-shaped lid and cylinder on the lateral side of separator.

Description

technical field [0001] The invention relates to an accessory of a vacuum cleaner, in particular to a cyclone separator installed in a dust cup of the vacuum cleaner. Background technique [0002] The separator is a key component of the dust cup of the vacuum cleaner. Its performance is directly related to the use effect and service life of the vacuum cleaner. In order to achieve a better dust separation effect, various forms of separators matching the dust cup of the vacuum cleaner have come out one after another. The dust cup with the existing separator generally has a disadvantage, that is, when the vacuum cleaner restarts after working intermittently, it will often produce the phenomenon of fine dust sucking back, so that the fine dust will suck back and adhere to the filter. It will increase the motor load and affect the dust collection effect. In order to overcome the above defects, people often use the method of increasing the height between the bottom of the separator...

Problems solved by technology

The dust cup with the existing separator generally has a disadvantage, that is, when the vacuum cleaner restarts after working intermittently, it will often produce the phenomenon of fine dust sucking back, so that the fine dust will suck back and adhere to the filter. It will increase the motor load and affect the dust collection effect. In order to overcome the above defects, people often use the method of increasing the height between the bottom of the separator and the dust cup dust collection chamber to prevent fine dust from sucking back and increase the dust collection chamber capacity. The dust cups of all kinds of separators are relatively high, which increases the volume and manufacturing cost of the vacuum cleaner

The application number of my design application is "20061055619.5", "a cyclone-type secondary separation dust cup" and the application number is "200720105518.7", "two-section three-time cyclone separation dust cup of vacuum cleaner", all of which are used at the lower end of the conical simplified body of the separator The method of connecting an isolating ring, there is an annular gap between the inner wall of the isolating ring and the outer wall of the lower end of the conical cylinder, and the separated fine dust is affected by the cyclone airflow, and falls along the inner wall of the isolating ring through the annular gap between the two into the dust collector. At the bottom of the cavity, although this technical solution can effectively avoid the phenomenon of fine dust sucking back, but because the bottom of the isolation ring of the above two patent applications is closed by the bottom cover, it limits the volume of the dust collection cavity for accumulating fine dust. To increase its capacity, the bottom plate must be moved down, and at the same time, the lower end of the isolation ring must also be moved down at the same time, increasing the height of the isolation ring, so that the fine dust entering the isolation ring is not easy to discharge
