Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention rotates a rotating brush by a driving wheel that rolls in contact with the floor surface, and the dust on the floor surface is attached to the main body case by this rotating brush. This invention relates to a floor cleaning tool that is placed inside a dust case.

[Prior art]

With this type of conventional device, the contact dimension between the rotating brush and the floor surface cannot be changed, so depending on the type of floor surface, the amount of interference between the rotating brush and the floor surface changes, making it impossible to clean efficiently. Nakatsuta.

[Summary of the invention]

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional art, and includes a switching member that is provided horizontally slidably on the main body case, and has a protrusion that comes into contact with a retaining plate that has a concave portion and an inclined portion at the lower part of the switching member. The driving wheel supported by the retaining plate protrudes downward from the main body case by varying the amount of protrusion downward from the main body case depending on whether the protruding portion abuts a concave part of the retaining plate or another part. By changing the contact dimensions between the rotating brush and the floor surface, the amount of interference between the rotating brush and the floor surface does not change even if the type of floor surface changes, allowing efficient cleaning at all times. The purpose is to provide cleaning tools.

[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 in between. Reference numeral 6 denotes a dust case detachably attached to the rear side of the main case 1, which is also divided into an upper case 7 and a lower case 8, and a coupling ring 10 is attached to the upper case 7 and the lower case 8 so as to be rotatable in the vertical direction. being held in place. Further, one end of the connecting pipe 9 is rotatably fitted into a coupling ring 10, and the other end of the connecting pipe 9 is connected to a vacuum cleaner as required. 11 is a comb blade provided on the front side of the lower case 8, and a rotating brush 12 is attached to the inside of the suction port 23 at the bottom of the main case 1.
We are starting to come into contact with people. Reference numeral 14 denotes a holding plate that rotatably supports the driving wheel 13 via a shaft 15 at both ends.The holding plate 14 is provided in the main body case 1 so as to be movable up and down, and the holding plate 14 has recesses 16 and the like at a plurality of places. A continuous slope portion 17 is provided. Reference numeral 41 denotes a switching member that is horizontally slidable between the upper case 2 and the holding plate 14, and has a switching knob 18 and a holding plate 1 at the bottom.
It has a convex rib 19 that comes into contact with 4. 40 is a spring provided between the holding plate 14 and the lower case 3. Reference numeral 20 indicates driven wheels that are provided at both ends of the rotating brush 12 and come into contact with the driving wheel 13 . 21 and 22 are flexible sealing tongues provided before and after the suction port 23 on the bottom surface of the lower case 3, and the rear sealing tongue 21 is longer than the front sealing tongue 22. 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.
Further, the coupling ring 10 is approximately T as shown in FIG.
When air is taken in from the intake ports 25 on both sides, the airflow collides in the center, creating a vortex and increasing noise.To prevent this, the connecting pipe 9 is
A wind rectifying wall 26 is provided at a portion where air flows out. Reference numeral 29 denotes a recess formed on the bottom surface of the lower case 3. The fixing knob 27 is attached to the guide rib 28 of the lower case 3 via a locking piece 30 so as to be able to slide within this recess 29. 3
A rotating shaft 12a of a rotating brush 12 is removably fitted into the rotating brush 1. 32 is a brush attached to the front side of the bottom of the lower case 3 so as to be in contact with the floor surface and swingable only on the rear side; 33 are follower wheels attached to the left and right sides.

In the above configuration, when the main body case 1 is moved, the driving wheel 13 installed on the lower case 3 rotates in contact with the floor surface, and the rotating brush 12 is moved in the direction of movement of the main body case 1 via the driven wheel 20 in contact with the driving wheel 13. The dust case 6 is rotated in the opposite direction to push the dust on the floor into the dust case 6. Furthermore, when attaching and detaching the rotating brush 12, the rotating shaft 12a of the rotating brush 12 can be attached and detached from the U groove 31 by sliding the fixed knob 27 against the guide rib 28 via the locking piece 30. can. Therefore, the lint etc. entangled with the rotating brush 12 can be removed from the rotating brush 12.
It can be easily removed by removing it. In addition, soft dust such as cotton dust may adhere to the surface or inside of the rotating brush 12, and even if it is once removed, there is a risk that it will adhere to the floor again.
Soft dust attached to the dust case 6 can be removed with a comb blade 11 provided on the lower case 8 of the dust case 6.
Also, when the switching knob 18 of the switching member 41 is slid in the horizontal direction depending on the type of floor surface, the convex rib 19
contacts the recessed part 16, inclined part 19, and other parts of the upper part of the retaining plate 14, and the amount of downward protrusion of the driving wheel 13 from the main body case 1 changes, thereby causing contact between the rotating brush 12 and the floor surface. The dimensions are changed, the amount of interference between them is made appropriate, and efficient cleaning can be performed. Further, although cleaning is performed by moving the main body case 1 back and forth, dust in the corners does not come into contact with the rotating brush 12. In this case, the brush 32 provided on the front side of the lower case 3 is used to catch and move the main case 1 when it is pulled toward you, and the next movement of the main case 1 causes the rotary brush 12 to pick up this dirt. be able to. Further, when a vacuum cleaner is connected to the connecting pipe 9 and used like a normal vacuum cleaner, the rotary brush 1
It is possible to increase the degree of vacuum on the floor surface that comes into contact with the
Dust can be smoothly sucked and moved, and dust inside the jutan can be collected. Also, the rear sealing tongue 21 is replaced with the front sealing tongue 22.
By making it longer, the resistance during operation can be reduced.

〔Effect of the invention〕

As described above, in the present invention, a concave portion and an inclined portion are provided in the upper part of the retaining plate that supports the driving wheel, and a protruding portion that comes into contact with the upper part of the retaining plate is provided in the lower part of the switching member that is slidably provided in the main body case. By sliding the switching member, the amount of protrusion of the driving wheel from the main body case is changed, and the contact dimension between the rotating brush and the floor surface is changed. Even if the type of floor surface changes, the contact between the rotating brush and the floor surface is maintained. This prevents the amount of interference from changing and allows efficient cleaning to be performed at all times.
