The present invention relates to a dusting device, and more particularly to a dusting device capable of being quickly detachably assembled to a cleaning machine and operating with lower power consumption.
The prerequisite step of floor dusting is to sweep the floor. The ways to sweep as known is performed with a sweep or a rag by humans. However, both ways as mentioned above are time-consuming and laborious. Although a vacuum cleaner can be used to suck up dust and dirt, it is still needed to be controlled manually for its moving.
To increase the efficiency of the prerequisite cleaning step, automatic cleaning machines which collect dust by suction were developed. These machines are configured to suck in dust from the bottom while moving, or are equipped with a bristled tool for brushing the floor being vacuum-cleaned. A traditional automatic cleaning machine typically operates on a built-in motor, which drives a rotary element into rotation. The rotary element is provided with plural bundles of bristles, generally made of nylon. Once the rotary element starts rotating, the bristles in contact with the floor sweep clean the floor. However, the bristles do not work effectively, especially for dirt or splotches on the floor. Furthermore, each rotary element is pivotally connected to a motor provided inside the cleaning machine, and is driven by the motor to rotate. In other words, if the cleaning machine is configured with two rotary elements, two motors are required to separately drive the two rotary elements. As a result, the more motors are equipped, the more costs of assembling and manufacturing are increased, and the more power of the cleaning machine is consumed. Moreover, too many motors will also raise the risk of malfunction. On the other hand, traditional cleaning machine is moved with two wheels configured on left and right sides of the bottom of the cleaning machine, and the two rotary elements are configured in front of the two wheels. It is noted that the cleaning machine is not moving in a fixed direction that is to say, moving backwards and forwards, or left to right is all possible to take place. However, the wheels on rotation are likely to leave dirt from itself on the floor when the cleaning machine is moving. Therefore, the cleaning machine cannot efficiently clean the dirt left by the wheels through only the rotary elements configured in front of the wheels.
Accordingly, an object of the present invention is to provide a dusting device being capable of operating with lower power consumption for the purpose of energy saving.
Another object of the present invention is to provide a dusting device having a structure capable of being quickly easily assembled to or detached form a bottom of cleaning machine for conveniently replacement of dusting components, and being widely applicable to most cleaning machines without changing internal configuration of the cleaning machine.
To achieve the above-mentioned objects, the dusting device of the present invention is capable of detachably assembled to a bottom of the cleaning machine, and comprises at least a first rotary disc comprising abase board, a linking portion formed on the base board, and a connecting portion disposed on the linking portion, the linking portion having a first groove formed thereon, one end of the connecting portion being pivotally connected to the bottom of the cleaning machine and driven to rotate by a motor installed in the cleaning machine; at least a second rotary disc comprising a base board, a linking portion formed on the base board, and a connecting portion disposed on the linking portion, the linking portion having a second groove formed thereon, one end of the connecting portion being pivotally connected to the bottom of the cleaning machine. Dusting elements are respectively attached to the base boards of the at least a first rotary disc and a second rotary disc, and are in contact with a surface to be cleaned. At least a driving rope unit is movably disposed on the first and second grooves and is driven to rotate in conjunction with rotation of the first rotary disc so as to further drive the second rotary disc to rotate simultaneously, whereby enabling the dusting elements to rotate to dust and clean the surface to be cleaned.
In one aspect of the present invention, the dusting device further comprises at least an idler pulley comprising a shaft rod and a pulley body formed on one end of the shaft rod, the pulley body including a first guiding slot and a second guiding slot, the shaft rod pivotally connected to the bottom of the cleaning machine and located between the first and second rotary discs, the driving rope unit comprising a first driving rope and a second driving rope, the first driving rope movably disposed on the first groove and the first guiding slot, and the second driving rope movably disposed on the second groove and the second guiding slot, wherein when the first rotary disc rotates, the idler pulley is driven by the first driving rope to rotate and further drives the second rotary disc to rotate with the second driving rope, so as to enable the dusting elements to rotate to dust and clean the surface to be cleaned.
In another aspect of the present invention, the at least an idler pulley and the first and second rotary discs cooperatively form a set of the dusting device, and the cleaning machine is configured with two sets of the dusting devices peripherally arranged on the bottom of the cleaning machine.
The dusting device of the present invention utilizes the cooperation of the idler pulley, the first rotary disc, the second rotary disc, the first driving rope, and the second driving rope to effectively reduce power consumption, enable quickly and easily assembly and highly compatibility, whereby successfully overcoming drawbacks that traditional cleaning devices are relatively inconvenient to be assembled, detached, replaced, and requires much higher power consumption.

Particularly, the driving rope unit 4 comprises a first driving rope 41 and a second driving rope 42, and both of the first and second driving ropes 41 and 42 have a ring shape. The first and second rotary discs 3 and 5 are respectively linked to the idler pulley 2 through the first and second driving ropes 41 and 42. Specifically, the first driving rope 41 is movably disposed on the first groove 321 and the first guiding slot 211, and is capable of moving on the first groove 321 in conjunction with rotation of the first rotary disc 3 so as to drive the idler pulley 2 to rotate simultaneously, wherein the first driving rope 41 rotates around and on the first groove 321 and the first guiding slot 211. The second driving rope 42 is movably disposed on the second groove 521 and the second guiding slot 212, and is capable of moving on the second guiding slot 212 in conjunction with rotation of the idler pulley 2 so as to drive the second rotary disc 5 to rotate and to allow the second driving rope 42 to rotate around and on the second groove 521 and the second guiding slot 212. The middle rim 213 is configured to prevent the first and second driving ropes 41 and 42 from interfering with each other.
In the preferred embodiment, the first and second guiding slots 211 and 212, and the first and second grooves 321 and 521 respectively have a same radial width so that the first and second rotary discs 3 and 5 rotate at a same speed, whereby providing an evenly cleaning effect on the surface to be cleaned. Furthermore, the idler pulley 2 has a bottom surface which is located at a position lower than or equal to bottom surfaces of the base boards 31 and 51 of the first and second rotary discs 3 and 5, so as to allow the dusting elements 6 to completely contact the surface to be cleaned. Particularly, the first and second driving ropes 41 and 42 are made of flexible material, for example, such as rubber, so as to be tightly attached to the first and second grooves 321 and 521, and the first and second guiding slots 211 and 212.
The dusting device 1 of the present invention is use, actuate the cleaning machine 7 to enable the motor 73 to drive one of the first rotary discs 3 to rotate in a clockwise direction (or anticlockwise direction); meanwhile, the idler pulley 2 is driven by the first driving rope 41 to rotate in the same direction as the first rotary disc 3 and further drives the second rotary disc 5 to rotate in the same direction through the second driving rope 42 (as shown in
