Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the structure of a rotating brush installed in a suction tool of a vacuum cleaner.

0002

[Conventional technology]

Generally, in vacuum cleaners, the suction device is equipped with a rotating brush, and this rotating brush is The air turbine or electric motor built into the suction port rotates the carpet. There are well-known products that make cleaning easier.

0003 The structure of a general suction tool will be explained using FIG. 4. In Figure 4, 1 is the suction This suction tool main body 1 is formed with a suction port 2 that opens to the floor side. A rotating brush 3 is rotatably supported so as to be exposed to this suction port 2. Ru. A pulley portion 4 is provided integrally with the rotating brush 3 on one end side of the rotating brush 3. The rotational force is transmitted to the rotating brush 3 by the belt 5 connected to the pulley part 4. is being reached. 6 is a magnet electric built in this suction tool body 1 The belt 5 is connected to the output shaft 6 of the motor 6. The rotating brush 3 is rotated by this.

0004 As the rotating brush 3, for example, as shown in FIG. For example, as shown in Figure 6, there is a type with a thin plate made of rubber or other material. Two types are known: one with Ipu and one with Ipu. First, brush bristles as shown in Figure 5 To explain the structure of the rotating brush 3A, which has a 3A, a groove 9 is formed in a spiral shape on the outer periphery of a rotor 8A made of a resin material. Brush bristles 10 whose tips protrude from the groove 9 are planted at appropriate intervals in the groove 9. be. The brush bristles 10 are flexible and can be rotated to clean the carpet. It penetrates into the hair and scrapes out dust, lint, hair, etc. from inside. Ma Regarding the structure of the rotating brush 3B of the type provided with a thin plate made of material such as rubber, etc. To explain, this rotating brush 3B is made of soft vinyl chloride, for example, on the outer periphery of the rotor 8B. A flexible thin plate 11 made of a material such as a ball is provided in a spiral shape. . This thin plate 11 also penetrates into the carpet hair like the above-mentioned brush bristles. It has the effect of scraping out dust, lint, hair, etc.

[0005] By the way, when cleaning is performed with the rotary brush 3A in which the brush bristles 10 described above are implanted, the floor Lint and hair on the surface tend to get entangled with the rotating brush 3A. This is shown in Figure 7. , the scraped lint and hair get deep into the roots of the brush bristles 10, causing the rotating brush to Even with the rotational force of 3A, the lint and hair cannot be blown away and become tangled. It is something. The more densely the brush bristles are planted, the more this entanglement occurs. child If lint or hair gets entangled as shown in the figure, the brushing force of the brush bristles 10 will deteriorate, so do not use it properly. It is necessary to remove the tangled lint and hair, but the work is very time-consuming. It is often left as it is because it is troublesome and it gets your hands dirty.

[0006] On the other hand, the rotary brush 3B provided with the thin plate 11 is free from lint and hair as described above. There is no room for lint or hair to get tangled. However, this thin plate 1 Even if 1 is flexible, it collides with the floor with a certain amount of force, so the floor itself is flexible. This is not a problem when cleaning carpets that have a tendency to dry. When cleaning the floor surface, there is a risk of damaging the floor surface due to the collision of the thin plate 11. Ta. Recently, the number of spaces between boards has increased, and cleaning between these boards has become more difficult. Rotating brushes are required to have the function of ``sweeping'' or ``polishing.''

[0007]

[Problem that the idea aims to solve]

As mentioned above, rotating brushes with bristles are gentle on the floor, but There is a problem with debris and hair getting tangled. On the other hand, a rotating brush provided with a flexible thin plate 11 There is no problem with lint or hair getting tangled, but there is a problem with damaging the floor surface.

[0008] In view of the above points, the present invention was developed using a rotating brush that produces less lint and hair and does not damage the floor surface. It provides the following information:

[0009]

[Means to solve the problem]

A predetermined length protrudes from the rotor on the outer periphery of the rotor, which is rotatably installed on the suction tool. For products with brush bristles, a flexible thin plate shorter than the length of the brush bristles is attached to the brush. Place between the rashi bristles.

0010

[Effect]

The brush bristles come into contact with the floor surface to scrape and sweep the floor surface. At this time The length of the flexible thin plate that protrudes from the brush bristles is shorter than the brush bristles, so it does not touch the floor surface. do not have. When cleaning with this rotating brush, lint and hair get wrapped around the brush bristles. However, since there is a flexible thin plate between the brush bristles, lint and hair are removed from the brush bristles. Don't go deep inside.

【Example】

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

0012 Figure 1 is a sectional view of a rotating brush according to an embodiment of the present invention, Figure 2 is an enlarged view of its main parts, and Figure 3 is a rotating brush. It is a perspective view of a rolling brush. In FIGS. 1 to 3, 12 is a rotating brush. This rotating brush 12 is provided with a predetermined length on the outer periphery of a rotor 13 that is rotatably provided. Brush bristles 14 protruding from the rotor 13 are installed, and the length of the bristles 14 is shorter than that of the brush bristles 14. A flexible thin plate 15 is provided between the brush bristles 14. The rotor 13 is made of resin. It is made of a material, and a shaft portion 16 is integrally provided at both ends. 4 is the pulley part be. The brush bristles 14 are spirally arranged in two rows around the outer periphery of the rotor 13. The brush bristles 14 are arranged symmetrically with respect to the axis of the rotor 13. the above The flexible thin plate 15 is arranged so as to be hidden between the brush bristles 14 as shown in FIGS. 1 and 2. The protruding length thereof is formed to be slightly shorter than the brush bristles 14. This soft The flexible thin plate 15 is made of a resin material such as soft vinyl chloride, and is made of a resin material such as soft vinyl chloride. It is adapted to be flexibly bent together with the lash bristles 14. In addition, this flexible thin plate 15 The protrusion length is determined by the rotation of the rotary brush 12 so that the brush bristles 14 and the flexible thin plate 15 reach the floor. The flexible thin plate 15 is shaped to such a length that it does not touch the floor surface when it is curved in contact with the floor surface. will be accomplished.

[0013] In the case of the rotating brush 12 mentioned above, cleaning will remove lint and hair 1 as shown in FIG. Even if the threads 7 get entangled with the rotating brush 12, the flexible thin plate 15 will remove the lint and hair 17. Because it is between the bristles 14, it does not penetrate deep into the brush bristles 14, and the brush bristles 14 It wraps around the tip of the. If this is the case, short lint, hair 17 is thrown away by the rotation of the rotating brush 12 and sucked into the vacuum cleaner. parable long Even if thread waste or hair 17 gets wrapped around it, it can be easily removed. Sunawa However, in the case of a conventional brush in which only the bristles 14 are implanted, thread waste and hair 17 get wrapped around the brush. It goes deep into the brush bristles 14 and is wound so that it touches the outer periphery of the rotor 13. It is extremely difficult to remove as it sticks to the surface. However, as in the embodiment of the present invention, the brush bristles A flexible thin plate 15 is interposed between the brush bristles 14 and lint and hair 17 are trapped deep inside the brush bristles 14. It does not get in and can be easily removed because it is located near the tip of the brush bristles 14. It is.

[0014] On the other hand, if this rotating brush 12 is used for cleaning, the densely arranged brush bristles 14 will clean the floor. Sweep and polish the surface to pick up dust, lint, and hair from the floor and suck it up. Make it easy to read. In this case, the flexible thin plate 15 is shaped slightly shorter than the brush bristles 14. Because of this, the gentle brush bristles 14 come into contact with the floor surface even between the boards. The floor surface can be protected by this.

[0015]

【effect】

As described above, according to the present invention, the area between the boards is improved by the sweeping and polishing effect of the brush bristles. It can be cleaned without damaging the floor surface. Also, the softness between the brush bristles The soft thin plate prevents lint and hair from penetrating deep into the brush bristles. , lint, and hair are less likely to get caught, and even if they do get caught, they can be easily removed.
