Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention rotates a rotating plan using a driving wheel that rolls in contact with a floor surface, and this rotating brush removes dust from the floor surface onto a main body case. This item is related to necessary cleaning items that can be stored in a dust case.

[Prior art]

In this type of conventional device, it is sometimes necessary to remove the rotating brush in order to remove dust attached to the rotating brush, but the mechanism for attaching and detaching the brush is complicated.

[Summary of the invention]

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional brush, and the rotating shaft of the rotating brush is removably fitted into and supported in the groove of a fixed knob slidably attached to the main body case. Another object of the present invention is to provide a floor cleaning tool that can simplify the attachment and detachment mechanism of a rotating brush.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 6, 1 is a main body case, which is divided into an upper case 2 and a lower case 3, which are integrated with a buffer 4 sandwiched therebetween. 6 is a dust case detachably attached to the rear side of the main case 1, and includes an upper case 7 and a lower case 8.
A connecting ring 9 is attached to a coupling 10 which is vertically rotatably clamped between an upper case 7 and a lower case 8 and which is rotatably fitted. IILIi
A comb blade provided on the front surface of the lower case 8 comes into contact with a rotating brush 12 provided in the suction port 13 at the bottom of the main case 12. Reference numeral 14 denotes a holding plate with shafts 15 attached to both ends, and system driving wheels 13 are rotatably fitted into the shafts 7 and 15, respectively. The holding plate 14 is provided with concave portions 16 and sloped portions 17 continuous with the concave portions 17 at a plurality of locations, and a convex rig 19 is provided opposite to these, and the holding plate 14 and the lower coos 3
A spring 40 is provided between the holding plate 14 and a button so that the holding plate 14 can be moved up and down by moving the switching knob 18 integrated with the convex lip 19 left and right. Dynamic It! 13
are in contact with the driven wheels 20 provided at both ends of the rotating brush 12, and the driven wJ wheels 2o are rotated in a direction away from the direction of rotation of the driving wheel 130. Numerals 21 and 22 are flexible sealing tongues attached after hjJ of the suction port 23 on the bottom surface of the lower case 3, and the rear sealing tongue 21 is longer than the front. A knob 24 is provided on the upper case 2 and is used to attach and detach the main case 1 and the dust case 6. The coupling 1° is approximately T-shaped, and when air is taken in from the intake ports 25 on both sides, the wind flows collide in the center, creating a vortex and increasing noise. By providing a rectifying wall 26 at a portion where air flows in, it is possible to reduce noise. Two are recesses formed in the bottom of the lower case 3, and the fixing knob 27 of the rotating brush 12 is attached to the idlip 2 of the lower case 3 so that it can slide in the recess 29.

The rotating shaft of the rotating brush 12 is fitted into the bait 31. 3
Reference numeral 2 denotes a brush attached to the bottom surface of the lower case 3 on the front side so as to be able to swing only to the rear side, and 33 denotes rear wheels attached on the left and right sides.

In the above configuration, when the main body case 3 is moved, the lower case 3
Hara installed in! The h4ff13 rotates in contact with the floor surface, and the rotating brush 12'? : Rotate in the opposite direction to the direction of movement of the main body case 1 to force M dust, etc. on the floor into the dust case 6.

Also, when removing the rotary brush 12 from the shaft 1, the fixed knob 27 is connected to the locking piece 30? : Guide lip 2 integrated with lower case 3 through
8, the rotating shaft 12a of the rotating brush 12 can be attached to and detached from the U#31. Also, for soft garbage such as cotton garbage, use the rotating brush 12.
There is a risk that the soft dirt that has adhered to the rotating brush 12 will be removed from the lower case 8 of the dust case 6. It can be removed with a knife 11. Also, depending on the type of floor surface, the interference scene between the rotating brush 12 and the floor surface changes, so depending on the type of floor surface, it may not be possible to clean efficiently. The rig 19 is engaged with the four parts 16 of the holding & 14, the holding plate 14 is pushed up by the spring 40, the position of the driving wheel 13, that is, the amount of protrusion from the lower case 3 is changed, and the rotating brush 1 is
2 can be an abrupt contact dimension. Also, when the brush 32, which is swingably attached to the front side of the lower case 3, is attached to the rotary plastic plate 12, the dust on the floor is caught and moved when it is pulled toward the front of the main case 1. It can be inserted by the rotating bluff 12 by the next movement of the main body case 1. Furthermore, the connection pipe f9 can be connected to a vacuum cleaner and used like a normal vacuum cleaner. The degree of vacuum in the area can be increased, dust can be moved smoothly, and dust inside the tube can be collected.

〔Effect of the invention〕

As described above, in the present invention, the rotating shaft of the rotating brush is removably fitted and supported in the groove of the fixed knob that is slidably attached to the main body case.9. The rotating brush can be attached and detached by sliding the fixed knob, and the mechanism for attaching and detaching the rotating brush can be made simple.

Therefore, the thread waste etc. entangled in the rotating brush can be easily removed by removing the rotating plan from the main body by sliding the fixed knob.
