Embodiment Construction
[0029] A vacuum cleaner equipped with a dust collection system according to a preferred embodiment of the present invention is shown in Figure 1-9, the reference number is 100. The vacuum cleaner 100 includes a vacuum cleaner housing 120 pivotally connected to a nozzle or vacuum cleaner base 110 . The base 110 is generally formed with a bottom nozzle opening (not shown) facing the floor surface. One or more rotating agitators (not shown) may be located in an agitator chamber (not shown) that communicates with the bottom suction nozzle opening. The agitator rotates to loosen the dust on the floor surface, and then the dust is removed by suction of the suction nozzle 110 . A dust collection system 130 is disposed within the housing 120 to separate and collect dust from the dust laden air flow from the suction nozzle 110 . The dust-laden air stream is driven by a suction motor 116 ( figure 2 ), the suction motor can be arranged in the base 110 or the housing 120.

A dust collection system of a vacuum cleaner includes a dust cup formed by a cylindrical side wall, and a disc-shaped member divides the dust cup into an upper part and a lower part. The dirty air flows from the upper part to the lower part through the gap between the outer periphery of the disc-shaped member and the side wall of the dust cup through the disc-shaped member. The disk member is supported on a centrally located delivery conduit having perforated walls above and below the disk member. The perforated walls allow airflow to flow into the delivery duct for further filtration or to exhaust the dust cup. The perforated wall above the disc allows airflow to fill the lower portion of the dust cup with large dust particles, and the perforated wall below the disc continues to flow through the dust cup as it becomes more and more restricted, improving durability. In various embodiments of the present invention, the air flow is directed through a delivery duct to a fine dust filter in a compartment at the bottom or top of the dust cup, or to a filter bag at the upper end of the dust cup. Or the fine dust filter can also be arranged in a separate container above or below the dust cup.
Description
technical field [0001] Generally, the present invention relates to ground maintenance implements. In particular, the present invention relates to dust collection systems for floor maintenance appliances such as vacuum cleaners. More particularly, the present invention relates to a dust collection device that is disposed within a dust collection container to prevent large dust particles from completely clogging the dust collection container, thereby allowing the ground maintainer to have a better performance between emptying operations of the dust collection container. Long-term maintenance performance. Background technique [0002] Upright vacuum cleaners are well known in the art. Such vacuum cleaners typically include a vacuum cleaner housing that is pivotally mounted to the base of the vacuum cleaner. The base is formed with nozzle orifices and may include an agitator mounted on top of it to loosen dirt and debris from the ground. A motor may be mounted on the base or...
