Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating brush device that is attachable to and detachable from the suction port of a vacuum cleaner as an attachment and is capable of effectively cleaning dust-attached surfaces from which it is difficult to remove dust.

Various accessories have been developed and used for vacuum cleaners depending on the purpose and application, but all of them are designed so that the tip opening of the suction port is brought close enough to the surface to be cleaned, with only a small gap between the two. This is based on the principle that by inhaling air from the air, the flow rate is increased to increase the dust suction effect. Therefore, conventional accessory parts such as various louvers, lattices, Venetian
In the case of dust that has adhered to the crosspieces of blinds, etc.,
Since air flows freely through the gaps between the crosspieces, the dust suction force cannot be sufficiently increased using the above-mentioned principle, and there is almost no dust suction effect. Furthermore, it is extremely difficult to clean the gaps between such crosspieces with a rag or duster.

In order to effectively utilize the vacuum cleaner's dust suction ability even for such special objects, the present invention has developed a vacuum cleaner that can be inserted into the suction pipe tube of the vacuum cleaner or at the tip of the suction port of the hose. The object of the present invention is to provide a rotating brush device with a simple structure for use in.

In order to achieve the above-mentioned object, the rotating brush device according to the present invention is provided with a propeller on a rotating shaft that can be detachably attached to the opening at the tip of the suction port, and the propeller is moved by the suctioned air.
The rotary shaft is rotated at high speed through the suction port, and a brush is provided on the part of the rotary shaft that protrudes from the tip of the suction port, so that the air sucked into the suction port effectively sucks up the dust floating by the brush that rotates with the rotation. It is characterized by being configured as follows.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of the present invention, which has an attachment tube 2 that is detachably attached to a suction tip opening lα of a suction tube l of a vacuum cleaner. Inside this mounting tube 2, bearings 4.4 are mounted on the central axis of the mounting tube 2 by means of an appropriate number of spoke members 8 (two spokes are shown in the diametrical direction in the drawing) at the front and rear ends. The rotating shaft 5 is supported by these bearings 4.about.4 so as to be rotatable but immovable in the axial direction. It is convenient to provide the mounting pipe 2 with a positioning ring 2α when inserted into the suction port la.

According to the features of the present invention, a suction opening portion l is provided on this rotating shaft 5.
A propeller 6 is fixed so as to be located within a, and a brush 7 is provided over a suitable range at the tip of a rotating shaft 5 that extends outward from the suction opening la.

With this structure, when the attachment pipe 2 is attached to the suction opening 1a and the vacuum cleaner is operated, the suction opening 1a
The propeller 6 is driven by the air sucked inside, and the rotary shaft 5 rotates at high speed together with the brush 7.

Therefore, as shown in FIG. 8, if the brush 7 is inserted into the gap of the looper 8, for example, the dust adhering to the looper 8 will be effectively wiped away by the brush 7 rotating at high speed, and the floating dust will be easily sucked in. It is sucked into the mouth la and can exert an excellent dust suction effect.

In the present invention, lengths and shortnesses of different sizes, shapes and properties are used.

By using various kinds of hard and soft replacement plush, in addition to the above-mentioned usage examples, a wide range of applications can be considered, such as between the keys of a typewriter, the groove of a window sash, and the gap between books on a bookshelf.

As mentioned above, the feature of the present invention lies in the fact that the intake airflow is effectively utilized for two functions: the power to rotate the brush and the suction of floating dust, and the two functions are combined.

FIG. 4 shows another embodiment of the present invention, in which the distal ends of a plurality of radial spoke members 9 are bent to form a locking portion 9α for locking to the suction port lα, and the proximal end of the spoke member 9 is bent. An elongated bearing 10 of an appropriate length is fixed at a position that coincides with the central axis of the suction port lα, and the rotating shaft 5 is regulated in the axial direction by a propeller 6 inside the bearing 10, and the rotating shaft 5 is regulated on the outside of the bearing 10. The axial direction is restricted by a collar 11 provided in the axial direction.

The operation and effect are similar to those shown in FIG.
