BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small vacuum cleaner, and more particularly, to a small vacuum cleaner which can be easily and conveniently cleaned of a cleaned area which is easy to carry and grip and which is relatively difficult to clean.

The vacuum cleaner includes an electric vacuum cleaner that incorporates a suction motor and sucks dust outside by collecting suction of dust with the suction power generated during its operation, and rotates the rotary brush installed at the suction port area by a wheel for rolling clouds. It is distinguished by a mechanical powerless cleaner that sweeps away.

Among such vacuum cleaners, electric vacuum cleaners perform cleaning of relatively large areas to be cleaned, mainly in homes or buildings. Thus, a dust bag replaceable in the dust collecting chamber is mounted, and a suction motor for sucking outside dust-containing air into the dust collecting chamber is provided. The dust collected in the dust bag can be simply discarded by periodically changing the dust bag.

By the way, since such an electric vacuum cleaner has a comparatively large capacity, there exists a problem that a user cannot carry easily and can clean easily. Therefore, among electric vacuum cleaners, a relatively small so-called handy vacuum cleaner is proposed. Such a handy vacuum cleaner is inconvenient to use because it requires a power source for its driving. In addition, although there is a rechargeable handy vacuum cleaner, there is a problem that can be used only for a predetermined time charged, the suction power is lowered as time passes and it can not be used for a relatively long time.

On the other hand, the mechanical non-powered vacuum cleaner has a relatively small size is easy to carry and grip, and also has the advantage that no power source for driving the device is required. 1 is a schematic side view of such a conventional mechanical powerless cleaner, and FIG. 2 is a cross sectional view of FIG. As can be seen from these figures, the conventional mechanical non-powered vacuum cleaner 1 includes a normal cleaning main body 3 having a dust inlet on its bottom face, a trap part 5 for receiving dust from the dust inlet 4, and The dust treatment part 21 is installed in the cleaning main body 3 and sweeps outside dust into the dust collecting part 5 through the dust inlet 4.

The cleaning main body 3 is opened from the rear surface of the dust inlet 4 to the back surface as a whole. The opening and closing pivot part 5 is coupled to this opening. The dust collecting part 5 has a normal dust collecting container 6 which forms the bottom face of the cleaning main body 3 and engaging ribs 7 extending upward from both sides of the dust collecting container 6, respectively. These coupling ribs 7 are formed with mutually opposing rotating holes. On the other hand, in the upper region of the side wall of the opening of the cleaning body 3, a rotation shaft is formed so as to protrude from each other and rotatably received in the rotation hole of the coupling rib 7, respectively.

The wheels 11a, 11b, 12a, 12b are coupled to the front and rear regions on both sides of the cleaning body 3, respectively. Among these, the drive gear 13 is provided coaxially in the center area | region with the one side wheel 12a of a rear area | region. This drive gear 13 provides a rotational force to the driven gear 15 of the dust processing part 21 mentioned later, and rotates the brush 25. As shown in FIG.

On the other hand, the dust treatment unit 21 is provided in the cleaning step (3), respectively, the double bent crankshaft 23, which is rotatably installed along the direction of the dust inlet (4), both horizontal stepped portions of the crankshaft (23) A pair of brushes 25 and a power transmission unit for transmitting the rotational force of the rear wheels 12a and 12b to the crankshaft 23 to rotate the crankshaft 23. The power transmission unit includes a drive gear 13 of the rear wheel 12a, wherein the driven gear 15 is coupled to one end region of the crankshaft 23, and the drive gear 13 and the driven gear. It consists of the clutch gear 14 interposed between the fourteen.

The pair of brushes 25 provided on both horizontal step portions of the crankshaft 23 are alternately exposed outwardly to the dust inlet 4 at the time of rotation of the crankshaft 23. Thus, it comes into contact with the dust on the cleaning surface of the region to be cleaned corresponding to the dust inlet 4.

By such a configuration, the conventional mechanical non-powered vacuum cleaner 1 pushes the user with a predetermined pressure in a state where the wheels 11a, 11b, 12a, 12b of the cleaning main body 3 are seated on the bottom surface of the area to be cleaned. The wheels 11a, 11b, 12a, and 12b move forward through the clouds. At this time, when the wheels 11a, 11b, 12a, 12b rotate, the rotational force is transmitted to the clutch gear 14 through the drive gear 13, and then to the driven gear 15. Thus, the crankshaft 23 rotates in response to the rotational speeds of the wheels 11a, 11b, 12a, and 12b. Then, the brush 25 coupled to the crankshaft 23 alternately contacts the bottom surface of the tungsten region through the dust inlet 4, and sweeps the dust on the bottom surface into the dust container 6.

On the other hand, the dust collected in the dust collecting container 6 can be easily processed by opening the back surface of the cleaning base body 3 by the user rotating the dust collecting part 5.

By the way, in the conventional mechanical non-powered vacuum cleaner 1, dust is cleaned while the cleaning base 3 moves the bottom surface of the area to be cleaned, and the brush 25 is moved in the direction in which the cleaning base 3 is moved. Since it is installed in the transverse direction and in contact with the bottom surface alternately, an area in which cleaning is not performed at regular intervals along the traveling direction occurs. Therefore, the cleaning state is poor, and in particular, it is difficult because the cleaning main body 3 must be reciprocated repeatedly for complete cleaning.

Accordingly, it is an object of the present invention to easily and conveniently clean the area to be cleaned, which is easy to carry and grip and relatively difficult to clean in view of such a conventional problem, and at this time, it is possible to perform good cleaning with a relatively small force. It is to provide a small vacuum cleaner that can.

It is another object of the present invention to provide a vacuum cleaner detachably coupled with a small vacuum cleaner that can be easily cleaned by separating the small vacuum cleaner when a narrow or difficult cleaning area is encountered while cleaning in a home or building. It is.

Here, the power transmission means, the drive gear coupled to the drive shaft; A driven gear coupled to the driven rotating shaft; A flywheel interposed between the drive gear and the driven gear; A first clutch gear for transmitting a rotational force of the drive gear to the flywheel; And a second clutch gear for transmitting the rotational force of the flywheel to the driven gear can be configured simply.

At this time, it further comprises an insert gear which is coaxially inserted into the flywheel and engaged with the first clutch gear; The second clutch gear is rotatably coupled to an extension shaft extending axially from the rotation shaft of the insert gear; Preferably, the electric belt is installed between the second clutch gear and the driven gear.

On the other hand, according to another field of the present invention, the above object, in the vacuum cleaner detachable small vacuum cleaner, forming a dust collecting chamber having a suction port, the device body having a receiving groove for receiving the small vacuum cleaner detachably on the outer surface ; Means for holding and holding said small vacuum cleaner in said receiving groove; And it is achieved by a vacuum cleaner, characterized in that it comprises an expansion tube coupled to the suction port of the device body and the end is in contact with the region to be cleaned.

The wheels 38 are provided on both sides of the dust trap 37, whereby the rolling can be moved forward and backward. The dust inlet 35 is formed at the bottom of the rotary brush receiving portion 33. This dust inlet 35 extends in the transverse direction to the moving direction of the cleaning main body 31. In the rotary brush receiving portion 33, a cylindrical rotary brush 51 is rotatably provided on the opening face of the dust inlet 35. The rotary brush 51 has a cylindrical rotary body 53 and a pair of rotary shafts 55 which protrude outwards along the longitudinal direction of the rotary body 53, respectively. A brush portion 57 is formed on the circumferential surface of the rotating body 53. Rotating holes 36 are formed on both side walls of the rotary brush receiving portion 33 to rotatably receive the rotary shaft 55 of the rotary brush 51. In the rotary brush 51 rotatably housed in the rotary brush receiving portion 33, the brush portion 57 is exposed through the dust inlet 35.

The dust trap 37 has an inclined surface 38 which forms a predetermined acute angle with respect to the bottom face at the opening edge which forms the dust suction opening 35. The inclined surface 38 allows dust present in the area to be cleaned to be easily wiped by the dust collecting part 37 while the rotary brush 51 rotates, while dust sweeping out of the dust collecting part 37 is outward. Prevent deviations.

The back 43 of the dust collecting part 37 is formed to be able to rotate up and down. The rear surface 43 is formed integrally with the dust trap portion 37, and consists of only the upper longitudinal edge portion 40 is blocked. And the engaging hook 41 protrudes in the lower center edge part of the back surface 43, and the hook groove 42 is formed in the bottom face of the trap part 37 correspondingly.

Meanwhile, the power transmission unit 61 includes a drive gear 63 coupled to the rotation shaft 39 of the wheel 38, a driven gear 65 formed on the rotation shaft 36 of the rotation brush 51, and a drive gear. The unit body 71 converts the driving force of the 63 into the rotational force of the driven gear 65. The drive gear 63 is coaxially coupled to the rotational shaft 39 of the wheel 38. On the other hand, the driven gear 65 can be formed integrally simply at the time of injection molding the rotating body (53) of the rotary brush (65).

The unit body 71 includes a flywheel 73 interposed between the drive gear 63 and the driven gear 65, a first clutch gear 75 for transmitting the rotational force of the drive gear 63 to the flywheel 73, and The second clutch gear 77 transmits the rotational force of the flywheel 73 to the driven gear 65. The unit body 71 is accommodated in the unit bracket 81 which is coupled to the upper surface of the dust collecting portion 37. The unit bracket 81 includes a gear accommodation portion 83 for accommodating the drive gear 63 and the first clutch gear 75 engaged with the drive gear 63 and a flywheel accommodation portion for accommodating the flywheel 73 ( 85) is formed. The flywheel 73 is arranged to maintain a predetermined distance from the drive gear 63 in the upper region of the flywheel accommodation portion 85.

The flywheel 73 has an insert gear 79 coaxially formed in the center region. The insert gear 79 meshes with the first clutch gear 75. In addition, the rotation shaft 69 for coaxially coupling the flywheel 79 and the insert gear 79 extends in one direction. On the other hand, both sides of the wall of the unit bracket 81 is formed with a bearing hole, one end of the rotation shaft 69 of the flywheel 79 is rotatably housed in the one bearing hole. The other end of the rotation shaft 69 of the flywheel 79 extends outwardly through the other bearing hole of the unit bracket 81.

 The second clutch gear 77 is coupled to the rotation shaft 69 of the extended flywheel 79. The second clutch gear 77 is opposed to the driven gear 65 of the rotary brush 51, and an electric belt 67 is coupled between the second clutch gear 77 and the driven gear 65. .

With this configuration, the small vacuum cleaner 30 is advanced by rolling movement of the wheel 38 when the user pushes the wheel of the cleaning main body 30 to a predetermined pressure while the wheel of the cleaning body 30 is seated on the bottom surface of the cleaning area. . When the wheel 38 rotates, the rotational force is transmitted to the first clutch gear 75 through the drive gear 63 and then to the flywheel 73. At this time, the fly wheel 73 serves to maintain the driving force transmitted from the wheel 38 for a predetermined time without sudden interruption.

On the other hand, the driving force transmitted to the flywheel 73 is transmitted to the driven gear 65 via the electric belt 67 via the second clutch gear 77. Then, the rotary brush 51 rotates in response to the rotational speed of the wheels 38. Then, the brush portion 57 of the rotary brush 51 contacts the bottom surface of the region to be cleaned through the dust inlet 35, and sweeps the dust on the bottom surface into the dust collecting portion 37. At this time, while the cleaning main body 31 moves, the brush portion 57 of the rotary brush 51 continuously contacts the bottom surface of the area to be cleaned, whereby a good cleaning state can be achieved. The rotary brush 51 may be rotated by moving the cleaning main body 31 in the reverse direction to perform cleaning of the area to be cleaned.
