Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating cleaning body for a vacuum cleaner, and in particular, it is capable of storing cotton-like materials such as lint and cotton waste on the floor in a dust room without becoming entangled. The present invention also relates to a rotating cleaning body for a vacuum cleaner with improved dust collection performance.

Conventionally, in the rotating cleaning body of a vacuum cleaner, a generally cylindrical rotating brush with a large number of brush bristles arranged radially around an axis is common.
), by rotating the Mukuro rotating brush, the dust on the floor can be flipped up and stored directly in the dust room, or when used in conjunction with the air intake, it can be transported to a designated trash storage box.
j) This is the general form of a vacuum cleaner, but in such a rotating cleaning body, the tips of the brush bristles tend to pick up lint, hair, cotton waste, etc., making it difficult to store them in the dust room.
There is a drawback that P wrapped around the rotating brush gets tangled, which causes the brush bristles to fall over and deteriorates the storage performance of the vacuum cleaner. This prevents lint, hair, cotton waste, etc. from getting entangled, but the effect is not satisfactory, and this has been a long-standing problem with vacuum cleaners of this type. .

For this reason, this product eliminates the drawbacks of the conventional products as described above and prevents lint, hair, cotton waste, etc. on the floor surface from becoming entangled during cleaning, thereby allowing smooth cleaning. has been proposed by the same applicant. For example, there is Patent Application No. 216,589 filed on December 10, 1988 entitled "Rotating Cleaning Body in Vacuum Cleaner". Figures 1 to 3 show the rotary cleaning body of this vacuum cleaner, and the main body case 1 is a rectangular body with an open bottom surface consisting of a top plate and a circumferential side plate, and a handle for operating the machine is attached. (not shown).

The rotating cleaning body 3 is attached to both side plates 1a of the main body case 1, with driven wheels 2 fixed to both ends of its rotating shaft 4.

It is rotatably mounted at the center position in the front-rear direction of 1b.

Before and after the driven wheel 20, drive rollers 7.8 are rotatably attached to the main body case 1 so that their rolling force can be rationally transmitted to the driven wheel 2. Drive roller 7.8
When the rotary cleaning body 3 touches the floor surface, the outer peripheral portion of the rotary cleaning body 3 is also set at the most suitable position for sweeping up. Dust rooms 9 are provided at the front and rear positions of the rotary cleaning body 3 to store the dirt Z that has been swept up, and are opened to allow the dust to be removed when disposing of the trash (see Fig. (not shown).

As shown in FIG. 3, the rotary cleaning body 3 has a plurality of blades 1G fixed to one side thereof in the axial direction on the outer peripheral surface of the rotary shaft 4 so as to spread radially. Each blade 10 is made of a flexible elastic plate such as a rubber plate, a synthetic resin plate, or a metal splash plate, and is designed to flex sufficiently when it comes into contact with the floor 9. Further, the number of blades 10 may be arbitrary.

In the above configuration, when the main body case l is first placed on the floor, the lower surface of the drive roller 7.8 protruding from the lower opening comes into contact with the floor. In this case, rotating brush 3
Since the blade 10 in contact with the floor is bent,
The contact of said drive roller 7.8 with the floor surface is not hindered. Then, by sliding the main body case 1 on the floor in the front and back direction using a handle (not shown), the drive row 27
, 8 roll on the floor surface, and this drive roller 7.8
The rotary cleaning body 3 also rotates via the driven wheel 2 which is in pressure contact with the rotary cleaning body 3. As a result of this turn 1, the blade 10 of the blade 10, which had been bent due to contact with the floor surface, comes out of contact with the floor surface, so when it comes off, the elasticity that had accumulated inside it at the time of deflection removes dust etc. on the floor surface. It flips up and stores them in the dust room.

However, in the rotary cleaning body of this vacuum cleaner, the blade 10 needs to have appropriate elasticity to sweep up dust etc. on the floor, so it is necessary to use a thin and flexible material made of hard material. Since the blade 10 is made of an elastic plate, the blade 10 raised on the convex part 11 of the floor will not rotate when facing an uneven surface, as shown in Fig. 4 f1) to (c). There is a tendency for the shaft 4 to curve over the entire width I along the axial direction, which prevents contact between the recess 12 and the blade 10, and there is a possibility that the dust accumulated in the recess 12 cannot be swept away. Particularly, when dealing with a surface such as a carpet, which has numerous irregularities, it may be difficult to follow the irregularities on the floor surface and bring the tip of the blade 10 into sufficient contact with the floor surface.

The present invention eliminates the drawbacks of the conventional methods as described above, and eliminates lint, hair, cotton waste, etc. even when cleaning not only flat floors but also uneven floors. To provide a rotating cleaning body for a vacuum cleaner, which does not become entangled with objects, improves the ability to collect fine dust, and performs smooth cleaning.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The rotary cleaning body for a vacuum cleaner according to the present invention will be described in detail below based on embodiments shown in the drawings.

5 to 11 show the rotary cleaning body in the vacuum cleaner according to the present invention, and the only difference from FIGS. 1 and 2 is the rotary cleaning body 33, and other common parts. are indicated by the same reference numerals, and the explanation of the structure etc. will be omitted as it would be redundant.

As shown in FIG. 7 0)←), the rotary cleaning body 33 consists of a blade 101 and a rotating shaft 34, and the blade 101 has a large number of bristles 100, which are core materials, arranged adjacently in the same direction and bonded to each other. Alternatively, it is formed into a film shape by means such as welding. For the bridge 100, a flexible elastic material such as rubber, synthetic resin, or metal spring may be used.

The plurality of blades 101 formed in this manner are fixed onto the outer circumferential surface of the rotating shaft a4 in a direction in which each of the blades 100 becomes radial from the rotating shaft 34.

The number of blades 1010 may be arbitrary.

In the above configuration, when the main body case le is located on the floor surface, the drive row 2 protrudes from the lower opening of the main body case le.
The lower surfaces of 7 and 8 come into contact with the floor surface. In this case, the rotating cleaning body 3
Since the blade 101 in contact with the floor surface of roller 7.3 is bent, the contact of said roller 7.8 with the floor surface is not hindered. Then, by sliding the main body case 1 on the floor in the front and back direction using a handle (not shown), the drive roller 7
．． 8 rolls on the floor surface, and this drive roller 7.8
The rotary cleaning body 33 also rotates via the driven wheel 2 which is in pressure contact with the rotary cleaning body 33. Due to the rotation of this rotating cleaning body 33, the blade 10
The blade 101, which was bent when it came into contact with the floor, comes out of contact with the floor, so when it comes off, the elasticity that had accumulated inside it when it was deflected will kick up the dirt on the floor and throw it all away. It is stored in the dust room.

In this case, the bristles 100 are not independent and are made into a fill A-shaped blade 101 by means such as adhesion or welding, so that lint, hair, cotton waste, etc. are caught between the bristles 100. You can clean these items without them getting tangled.

In addition, if the floor surface is uneven, each blade 101 may be constructed in the form of a υ film by bonding or welding a plurality of bristles 100, as shown in FIG. 80) to (c). Therefore, the elasticity of the blade 101 in the radial direction is ensured, but the interlocking ability of the rotating shaft 34 in the axial direction is limited, so the blade 101 is
Even if the tip of the tip rises onto the convex portion 11, only the very vicinity tends to follow suit, but there is no tendency to curve over the entire width l. Therefore, as shown in FIG. B, f, the contact between the recessed portion 12 and the blade 101 is sufficiently ensured, and the fine dust accumulated in the four portions 12 can be swept away.

FIG. 9 shows another embodiment of the rotary cleaning body 102, in which the surface of the bristles 100 is coated with a very thin soft film 103 of plastic, glue, rubber, etc. possibly blade 1
Even if 01 is formed, the same effect as described above can be obtained.

Further, in the rotary cleaning body 104 shown in FIG. 10, a blade 101i is formed by providing a space between adjacent bristles ioo and coating with a very thin coating 103 of soft plastic or rubber. , and further a rotary cleaning body 105 shown in FIG.
The blade 101 is constructed by integrally forming the bristle 100 and the connecting plate portion 106 by integrally molding plastic, rubber, or the like. In such rotary cleaning bodies 104, 105, the bristles 1
oo Since it is possible to provide more independence between each other, the interlocking ability of the blade 101 in the axial direction of the rotating shaft 34 is more restricted, so that the blade 101 can ride on the convex gate on the floor. In this case, the tendency of the rotating shaft 34 to curve in the axial direction can be further eliminated, and the contact between the blade 101 and the floor surface can be made more sufficient.

In addition, in the said Example, the case where it was used for a manual vacuum cleaner was demonstrated, but it is needless to say that it may be used for a vacuum cleaner without being limited to this.

With the above-described configuration, the present invention prevents lint, hair, cotton waste, and other flocculent materials from getting entangled when cleaning not only a flat floor surface but also an uneven floor surface -F. This has the excellent effect of not only being able to reliably prevent such problems, but also improving the ability to collect fine dust and ensuring smooth cleaning work at all times.
