Description

外置式吸尘器除尘装置  External vacuum cleaner dust removal device
技术领域 Technical field
本发明涉及一种外置式吸尘器除尘装置。  The invention relates to an external vacuum cleaner dust removing device.
背景技术 Background technique
传统的吸尘器中安装有过滤装置, 目的是将吸入的脏空气进行过滤, 把灰 尘颗粒留在集尘装置中, 因此, 此类吸尘器在使用一段时间以后, 用户应将过 滤装置进行清理或更换, 否则, 过滤装置的滤孔被细灰尘堵塞后, 会增大真空 电机的阻力, 严重者甚至会烧坏电机, 不仅给用户带来了麻烦, 而且也会影响 吸尘器的性能和寿命。  A conventional vacuum cleaner is equipped with a filtering device for filtering the inhaled dirty air to leave dust particles in the dust collecting device. Therefore, after using the vacuum cleaner for a period of time, the user should clean or replace the filtering device. Otherwise, the filter hole of the filter device is blocked by fine dust, which will increase the resistance of the vacuum motor. In severe cases, the motor will be burnt out, which not only causes trouble to the user, but also affects the performance and life of the vacuum cleaner.
近年来, 厂商根据旋风分离的原理, 用旋风除尘装置来替代过滤装置, 取 得了较好的除尘效果, 因此而广泛地应用到吸尘器上。 该旋风除尘装置于尘杯 内设置一个上端大、 下端小的锥形筒体, 锥形筒体的上端纵向设置一出风管, 锥形筒体的下端开口以便于灰尘落入尘杯底部, 进风管于锥形筒体上部侧壁并 沿切线方向进入, 使带有灰尘的气流在锥形筒体内产生旋风, 灰尘颗粒在离心 力的作用下沿锥形筒体侧壁下落到集尘盒底部, 除尘后的气流向上经出风管排 出。  In recent years, according to the principle of cyclone separation, the manufacturer uses a cyclone dust removal device instead of the filter device to obtain a better dust removal effect, and thus is widely applied to a vacuum cleaner. The cyclone dust removing device is provided with a conical cylinder with a large upper end and a small lower end in the dust cup. The upper end of the conical cylinder body is longitudinally disposed with an air outlet tube, and the lower end of the conical cylinder body is open to facilitate dust falling into the bottom of the dust cup. The air inlet pipe enters the upper side wall of the cone cylinder and enters in a tangential direction, so that the dusty airflow generates a cyclone in the cone cylinder, and the dust particles fall along the side wall of the cone cylinder to the dust box under the action of centrifugal force. At the bottom, the airflow after dust removal is discharged upward through the air duct.
但是, 旋风除尘装置也存在着体积较大的缺点, 特别是风流量要求较大的 大型吸尘器上使用的旋风除尘装置体积就更大, 不仅增加了成本, 而且用户使 用也比较麻烦。  However, the cyclone dust removing device also has a large volume defect, and in particular, the cyclone dust removing device used on a large vacuum cleaner having a large wind flow demand is larger in volume, which not only increases the cost, but also is cumbersome for the user to use.
