Description
- 1. Field of the Invention
- The present invention relates to a dusting device and, more particularly, to a rotary type dusting device which is rotatable to perform sweeping as well as dusting.
- 2. Related Art
- 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 and clean the floor. However, the bristles do not work effectively, especially for dirt or splotches on the floor. An improved rotary element, therefore, includes plural strips of cloth in position of bristles. When rotated, the rotary element drives the strips of cloth to provide an enhanced cleaning effect. Since the strips of cloth are fixed to the rotary element, the entire rotary element must be detached in order to wash the strips. Moreover, the rotary element itself must not come into contact with water while the strips are washed, and this makes it difficult to wash the strips. In addition, the strips are likely to fall off when rotated and, if happening, will hinder the floor cleaning process. Also, the strips alone cannot be replaced after they have been used for a while; the rotary element must be replaced together with the strips, which incurs a considerable cost. Moreover, a traditional automatic cleaning machine is equipped with wheels at a bottom thereof for moving, and the rotary element is generally configured in front of the wheels. However, the cleaning machine is not moving in a fixed direction, and the wheels are likely to leave dirt from itself on the floor when the cleaning machine is moving. Therefore, the rotary element configured in front of the wheels cannot efficiently clean the dirt left by the wheels.
- Accordingly, an object of the present invention is to provide a rotary type dusting device that is detachably assembled to an automatic cleaning machine, and is capable of simultaneously providing sweeping and dust-absorbing effect, so as to achieve twice the result with half the effort into dusting work.
- Another object of the present invention is to provide a rotary type dusting device which is equipped with dusting components being easily and quickly detachable in order to provide low cost and high efficiency dusting work.
- To achieve the above-mentioned objects, the rotary type dusting device of the present invention comprises a connecting base pivotably connected to a bottom of the automatic cleaning machine so that the connecting base is capable of being driven to rotate by the automatic cleaning machine, the connecting base comprising a plurality of interference portions spaced apart from each other. A rotary disc is detachably connected to a bottom of the connecting base, the rotary disc being coaxial to the connecting base and being rotatable in conjunction with the connecting base, the rotary disc comprising a plurality of positioning portions spaced apart from each other for correspondingly engaging the plurality of interference portions. An affixing element has an upper surface fixed onto a bottom of the rotary disc, and an affixing portion at a bottom of the affixing element. A dusting element comprises a first layer and a second layer, the first layer attached to the affixing portion so that the dusting element is rotatable in conjunction with the rotary disc to enable the second layer to dust a surface to be cleaned.
- In one aspect of the present invention, the connecting base further comprises a plurality of mounting portions arranged around the connecting base, each said mounting portion mounting a bundle of bristles, the bundle of bristles extending out of a periphery of the dusting element for contact with the surface to be cleaned so as to carry out sweeping.
- In another aspect of the present invention, the rotary disc further comprises a plurality of restraining portions, each said restraining portion configured between any two adjacent of the bundles of bristles near a periphery of the rotary disc and corresponding to the positioning portion in position for restraining transverse displacement of each said bundle of bristles, so as to prevent the bundles of bristles from being deformed by rotation of the connecting base.
- The rotary type dusting element of the present invention firstly utilizes the rotation of the bundles of bristles to sweep the surface to be cleaned and bring the dust to be sucked into the automatic cleaning machine, and then utilizes the rotation of the dusting element to clean and remove remaining dust from the surface to be cleaned, whereby providing dual-effect dusting work. Furthermore, the plurality of restraining portions are capable of preventing the bundles of bristles from being deformed by rotation of the connecting base, and the dusting element is easily and quickly to be attached to or detached from the rotary disc, whereby lowering a cost of assembly and overcoming drawbacks of conventional vacuum cleaners that are inconvenient to replace cleaning elements and providing only one effect of cleaning.

In this embodiment, the connectingbase 2 has a round shape and comprises a plurality ofinterference portions 21 and mountingportions 22 arranged around the connectingbase 2. Theinterference portions 21 are arranged around a bottom of the connectingbase 2 and are evenly spaced apart from each other. Two opposite sides of each of theinterference portions 21 respectively adjoin onemounting portion 22. In other words, each of theinterference portions 21 is configured between any two ofadjacent mounting portions 22, and is recessed from the periphery of the connectingbase 2 to form an oblique curved face (not labeled). Each of the plurality of mountingportions 22 is configured to mount a bundle ofbristles 23 being made of, but not limited to, flexible fiber strips. In particular, each bundle ofbristles 23 tilts downward and extends out of a periphery of thedusting element 5 in order to contact a surface to be cleaned (as shown inFIGS. 5 and 6 ). - The
rotary disc 3 has a round shape where an upper surface thereof is larger than the bottom of the connectingbase 2. Therotary disc 3 is detachably connected to the bottom of the connectingbase 2 in a manner of screwing, adhering or fastening. Therotary disc 3 is coaxial to the center of theconnecting base 2 and is rotatable in conjunction with theconnecting base 2. Therotary disc 3 comprises a plurality of positioningportions 31 spaced apart from each other, eachpositioning portion 31 protruding upward from the upper surface of therotary disc 3 and forms an oblique guidingface 311 for correspondingly engaging therecessed interference portion 21, so as to position therotary disc 3 onto the connectingbase 2. In other words, thepositioning portion 31 is located in between two mountingportions 22 after being engaged with the interference portion 21 (as shown inFIG. 2 ). Additionally, therotary disc 3 further comprises a plurality of restrainingportions 32 evenly spaced apart from each other around therotary disc 3. Each of therestraining portions 32 is configured to fit between any two adjacent bundles ofbristles 23 near a periphery of therotary disc 3 so as to strengthen the structural strength of therotary disc 3 at peripheral portions. Therestraining portions 32 are disposed corresponding to thepositioning portions 31 such that the positioningportions 31 as a whole are surrounded by therestraining portions 32. Furthermore, each of therestraining portions 32 protrudes upward from the upper surface of therotary disc 3 and has a thickness that is equal to or larger than a thickness of the bundle ofbristles 23. In this manner, the restrainingportions 32 are capable of restraining transverse displacement of each bundle ofbristles 23, so as to prevent the bundles ofbristles 23 from being deformed by rotation of the connectingbase 2. - The affixing
element 4 has an upper surface fixed onto a bottom of therotary disc 3, and an affixingportion 41 at a bottom of the affixingelement 4, the affixingportion 41 having a hook-and-loop structure (i.e., Velcro). The dustingelement 5 comprises afirst layer 51 and asecond layer 52. Thefirst layer 51 has a hook-and-loop structure for being attached to the affixingportion 41 so that the bottom of therotary disc 3 is entirely covered by the dustingelement 5. Thesecond layer 52 and thefirst layer 51 are made of non-woven fabric. The dustingelement 5 has multiple curved portions 53 (as shown inFIGS. 1 and 8 ) which are continuously curved and connected to form the periphery of the dustingelement 5. When the dustingelement 5 rotates, thecurved portions 53 being concave are capable of retaining dust and bringing the dust to be sucked in the automatic cleaning machine so as to improve efficiency of dusting. - It is noted that the periphery of the
rotary disc 3 is not over the dustingelement 5 in relation to position so as to avoid therotary disc 3 contacting the surface to be cleaned, and thus affecting the dusting work. In the preferred embodiment as shown inFIG. 4 , the number of the rotary type dusting device is 4, and the rotarytype dusting devices 1 are peripherally arranged around the bottom of theautomatic cleaning machine 6. More specific, the rotarytype dusting devices 1 are disposed in front of and behind the twowheels 61 at the bottom of theautomatic cleaning machine 6. In practice, dust and dirt are very likely to be attached to the twowheels 61 along the moving of theautomatic cleaning machine 6, and are therefore left on the surface to be cleaned. As a result, the arrangement of the four rotarytype dusting devices 1 are capable of cleaning the dust and dirt left by thewheels 61. - In use of the rotary
type dusting device 1, turn on theautomatic cleaning machine 6 to drive the connectingbase 2 to rotate. At the same time, the bundles of thebristles 23, therotary disc 3, and the dustingelement 5 simultaneously rotate on the same axis. Along with the moving of theautomatic cleaning machine 6, thesecond layer 52 of the dustingelement 5 is in contact with the surface to be cleaned to carry out dusting, while the bundles ofbristles 23 sweep the dust on the surface to be cleaned and bring the dust to be sucked into theautomatic cleaning machine 6. In this manner, the rotation of the bundles ofbristles 23 and the dustingelement 5 in combination successfully improves the efficiency of dusting and sweeping of theautomatic cleaning machine 6. Furthermore, once the dustingelement 5 is needed to be replaced, it can be quickly and easily to be detached by means of the hook-and-loop structure, whereby efficiently lowering a cost of assembly. - Referring to
FIG. 7 showing another embodiment of the present invention, the dustingelement 5 in this embodiment is shaped as a bag and is capable of being mounted around therotary disc 3 through an elastic opening. In this manner, the bag-like dusting element 5 is also capable of being detached and assembled quickly and easily, and does not affect the operation of the bundles ofbristles 23. Referring toFIG. 8 showing another embodiment of the present invention, a rear of the bottom of theautomatic cleaning machine 6 is further equipped with a cleaningcloth 62 for wiping or mopping the surface to be cleaned. - Accordingly, the rotary
type dusting element 1 of the present invention firstly utilizes the rotation of the bundles ofbristles 23 to sweep the surface to be cleaned and bring the dust to be sucked into theautomatic cleaning machine 6, and then utilizes the rotation of the dustingelement 5 to clean and remove remaining dust, dirt or splotches from the surface to be cleaned, whereby providing dual-effect dusting work. Furthermore, the plurality of restrainingportions 32 are capable of preventing the bundles ofbristles 23 from being deformed by rotation of the connectingbase 2, and the dustingelement 5 is easily and quickly to be attached to or detached from therotary disc 3, whereby lowering a cost of assembly and overcoming drawbacks of conventional vacuum cleaners that are inconvenient to replace cleaning elements and not capable of providing dual-effect cleaning. - It is understood that the invention may be embodied in other forms within the scope of the claims.
