Description:

TECHNICAL FIELD

This present invention relates to cleaning tools and, more particularly to a cleaning raker for dedusting.

BACKGROUND

At present, the cleaning raker in the market has a hand shank, movable pulleys, a brush and a dedusting driver. The hand shank is able to push and move the raker with the movable pulleys. The dedusting driver controls the brush to drive the brush to clean dusts. When cleaning dusts with the brush, the users just need to switch on the driver, then push and move the cleaning holder, the raker holder will move the brush and clean the dusts.

However, some problems restrict the use of the cleaning raker. For example, when a surface to be cleaned is a wool carpet, some dusts with static charge are easily adsorbed to the bottom of the carpet. Accordingly, it is difficult to completely clean these dusts with static charge due to interference of a wool layer on the surface of the carpet. This becomes a limitation to the clean function of the cleaning raker. Further, when cleaning a large bulk of dusts, as the brush is too soft, therefore, it is hard to clean the large bulk of dusts. Generally, such a large bulk of dusts is picked into a dustbin by hand, thus it brings inconvenience and low efficiency to cleaning operation.

Therefore, there is a need for a cleaning raker which can effectively improve cleaning efficiency.

SUMMARY

In accordance with an embodiment of the present invention, a cleaning raker is provided, which comprises a raker holder, a cleaning brush disposed on the raker holder, a dedusting driver for driving the brush and a vibration device provided at a bottom of the raker holder. The vibration device comprises a vibrating plate and a vibrating driver for driving the vibrating plate. The vibrating plate is connected to the vibrating driver.

Since the raker holder is provided with the vibrating device, dusts with static charge around the raker holder are stirred along with vibration of the vibrating plate under the drive of the vibrating driver. These dusts then are cleaned with the brush easily, thus the cleaning efficiency is significantly increased. As cleaning some large bulk of dusts, under the function of the vibrating plate, the vibration easily breaks down these large bulks of dusts, thereby preventing collecting such the large bulk of dusts by hand. This facilitates the clean of dusts and reduces the cleaning workload of the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Objects, advantages and embodiments of the present invention will be explained below in detail with reference to the accompanying drawings. However, it is to be appreciated that the following description of the embodiment(s) is merely exemplary in nature and is no way intended to limit the invention, its application, or uses.

Referring to FIG. 1, FIG. 2 and FIG. 3, a cleaning raker in accordance with a first embodiment of the present invention is shown. The cleaning raker includes a raker holder 1, a cleaning brush 11 disposed on the raker holder 1 and a dedusting driver 12 for driving the brush 11. A vibration device 2 is provided at a bottom of the raker holder 1. The vibration device 2 includes a vibrating plate 21 and a vibrating driver 22 for driving the vibrating plate 21. The vibrating plate 21 is connected to the vibrating driver 22.

Specifically, an operating hand shaft 13 is disposed on the bottom of the raker holder 1. Movable pulleys 14 are disposed on the bottom of the raker holder 1 at one end of the hand shaft 13. In use, the user holds the hand shaft 13 by hand to control rotation of the movable pulleys 14 and thereby move the raker holder 1.

The brush 11 is located at an opposite side of the raker holder 1 relative to the movable pulleys 14. The opposite side is a front end, which is generally close to a ground region to be clean during cleaning. As shown in FIG. 2, the dedusting driver 12 includes a dedusting motor 121, a first gear 122 and a second gear 123. The first gear 122 is connected to the dedusting motor 121. The second gear 123 is disposed on the brush 11 and is connected to a transmission portion of the first gear 122. In this structure, the dedusting driver 12 drives the brush 11 to clean the dusts on ground.

As shown in FIG. 3, a bracket 15 is provided on the bottom of the raker holder 1. The bracket 15 forms a gap 16 for receiving the vibrating device 2 therein such that the vibrating plate 21 can closely face toward the ground.

Referring to FIG. 3 through FIG. 5, in the illustrated embodiment, the vibrating driver 22 is a drive motor 221. An eccentric wheel 222 is provided on a power output shaft of the drive motor 221. The eccentric wheel 222 is connected to the vibrating plate 21. As a power of vibration, the drive motor 221 drives the eccentric wheel 222 to turn. When turning, the eccentric wheel 222 periodically touches and presses against the vibrating plate 21, thereby achieving a periodical vibration of the vibrating plate 21.

Referring to FIG. 6 and FIG. 7, another cleaning raker in accordance with a second embodiment of the present invention is shown. The cleaning raker in this embodiment has another vibrating driver different from the vibrating driver in the first embodiment. In this embodiment, the vibrating driver 22 is an electromagnetic valve vibrator 223. The electromagnetic valve vibrator 223 includes an electromagnetic oscillator plate 224 and an electromagnetic coil 225. The electromagnetic coil 225 is disposed in the electromagnetic oscillator plate 224. The electromagnetic oscillator plate 224 is connected to the vibrating plate 21. In this embodiment, the electromagnetic oscillator plate 224 is a C-shaped plate with an open at one side thereof. The electromagnetic coil 225 is disposed in the C-shaped electromagnetic oscillator plate 224 vertically. After the electromagnetic coil 225 is switched on, the electromagnetic oscillator plate 224 generates periodical vibration which is transferred to the vibrating plate 21, thereby driving the vibrating plate 21 to vibrate.

Referring to FIG. 8 and FIG. 9, still another cleaning raker in accordance with a third embodiment of the present invention is shown. The cleaning raker in this embodiment has still another vibrating driver different from the vibrating driver in the above embodiments. In this embodiment, the vibrating driver 22 is an ultrasonic generator 226. As the ultrasonic generator 226 generates ultrasonic wave, the ultrasonic wave is transferred to the dusts through the vibrating plate 21, accordingly achieving a good vibrating cleaning effect.

In the above-mentioned embodiments, the vibrating plate 21 is connected to the raker holder 1, for example, through a suspension device 17. The suspension device 17 is configured to buffer the impact as the vibrating plate 21 is vibrating. In some embodiments, the suspension device 17 can be selected from the group consisting of: silica, spring, cylinder, and hydraulic cylinder and other similar buffering structure.

In these embodiments, since the raker holder 1 is provided with the vibrating device 2, dusts with static charge around the raker holder 1 are stirred along with vibration of the vibrating plate 21 under the drive of the vibrating driver 22. These dusts are raised up and then cleaned with the brush 11 easily, thus the cleaning efficiency is significantly increased. As cleaning some large bulk of dusts, under the function of the vibrating plate 21, the vibration easily breaks down these large bulks of dusts, thereby preventing collecting such large bulk of dusts by hand. This facilitates the clean of dusts and reduces the cleaning workload of the operator.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
