Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a dust cleaner for an electric vacuum cleaner, which is attached to a front end portion of a suction pipe of the electric vacuum cleaner so that dust can be efficiently absorbed.

[0002]

[Prior art]

 Conventionally, various ideas have been already known for dust collectors that are generally attached to the tip of the suction pipe of an electric vacuum cleaner. In particular, a structure in which a brush is attached to the suction part is known as a structure in which the dust collecting tool is moved to scrape the dust adhering to the surface to be cleaned to suck the dust. There is also a configuration that incorporates a rotating brush in combination with the brush.

[0003]

[Problems to be solved by the device]

 The dust collector with the above-mentioned brush attached in the vicinity of the suction port is attached around the suction port when the dust collector is moved while pressing it against the surface to be cleaned in order to perform dust collection operation. As much as the surface to be cleaned is rubbed by the brush, it plays the role of scratching up the attached dust and moving it to the suction port. However, such a dust collector is effective when the surface is flat, and is not so effective when the surface having irregularities or the surface to be cleaned is a flexible surface such as a screen door. Can not be expected.

Further, in a dust collector of a type in which a brush is arranged around the suction port and a rotating brassiere is arranged inside the suction port, the suction port is inevitably wide, so that the suction area is large, Since the suction pressure decreases, the expected dust absorption effect cannot be obtained. Further, if the dust suction section becomes complicated, there is a problem that if the dust suction section is used for a long period of time, the dust suction operation section becomes dirty and unsanitary.

The present invention is intended to solve such a conventional problem, in which dust is absorbed by a large number of small suction tubes which can be supported even if the surface to be cleaned is not flat, and brushes arranged around the suction tube. It is an object of the present invention to provide a dust collector for an electric vacuum cleaner, which is structured so that the operation can be effectively performed and the portion that mainly sweeps the cleaning surface and exerts the dust collecting function can be removed and cleaned during cleaning depending on the frequency of use. .

[0006]

[Means for Solving the Problems]

 The present invention, which is configured to achieve such an object, is equipped with a dust suction head having a large diameter at one end and a large number of flexible suction tubes, and the other end having a suction head of an electric vacuum cleaner. In a dust collector for an electric vacuum cleaner, which has a suction connection port that can be connected to a pipe and has a hollow interior with an appropriate length, the dust suction head is fitted and fixed to the opening of the dust suction body, and the dust suction head is removed. The ring brush is provided so that its mounting ring portion is fitted around the outer peripheral edge portion of the dust suction main body and is detachably attached to the ring brush so that the brush is planted in the mounting ring portion of the ring brush. It is characterized in that it is longer than the suction tube provided in the.

Further, in the present invention, a plurality of thin flexible tubes are arranged in the array of the plurality of suction tubes in the dust suction head, and the tip of the tubes is made of a fiber having a high electrostatic chargeability. It is preferable to provide a dust brush in order to enhance the dust collection effect.

[0008]

[Action]

 The dust collector of the present invention thus constructed is attached to the tip of the suction pipe of the electric vacuum cleaner by fitting the suction connection port like the conventional dust collector. When the dust suction part is pressed against the surface to be cleaned and moved, dust on the surface to be cleaned is scraped up by the brush of the ring brush by the ring brush arranged on the outer peripheral part, and at the same time, a plurality of dust suction heads are moved. Since the suction tube is made of a flexible material, the tip of the opening bends in an arbitrary direction depending on the degree of pressing force and sucks dust generated by the brush of the ring brush. Therefore, even if the surface to be cleaned is not flat, it can be easily absorbed and cleaned, and since the opening of the suction tube that bends freely with the pressing force is small, at least the suction speed of each suction amount becomes faster. Therefore, the dust scratched by the ring brush is quickly sucked, and even the dust attached to the corners can be sucked. The ring brush that encloses a large number of suction tubes is detachably attached to the outer circumference of the dust suction body, so it can be removed and washed when it becomes dirty, so clean and sanitize the ring brush. be able to.

In addition, if a large number of suction tubes are arranged in the dust suction head and a dust collection brush made of highly electrostatically charged fibers is provided, static electricity generated by the dust collection brush when the surface to be cleaned is rubbed is reduced. The generated dust is sucked up by the suction tube located near the dust collection brush, and the dust absorption effect is enhanced.

【Example】

 Next, a specific example of an embodiment of the dust collector for an electric vacuum cleaner of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a cross section of a specific example of a dust collector of an electric vacuum cleaner according to the present invention, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIG. FIG. 4 is a sectional view showing an enlarged main part of the ring brush and the dust suction head.

In these drawings, the dust collector 1 of the vacuum cleaner according to the present invention is provided with a suction connection port 2 ′ that can be connected to a suction pipe of a vacuum cleaner that is not shown and is generally used at the other end. The dust suction head 5 includes a dust suction main body 2 into which the dust suction head 5 can be fitted and has a hollow inside, and a large number of flexible suction tubes 8 fitted and held in a large diameter portion of the dust suction main body 2, and A ring brush 10 is attached to the outer peripheral edge portion 2 ″ of the dust suction main body 2 so as to surround the dust suction head 5 and to be fitted and mounted.

As shown in FIG. 1, the dust collecting body 2 has an appropriate length from a dust collecting head mounting portion 3 having a large diameter for fitting and holding a dust collecting head 5 described later to a dust collecting rod end of a known vacuum cleaner. It has a hollow structure integrally formed with a fitting connection port 2 ', and is molded of synthetic resin.

The dust suction head 5 has a base 6 having an outer shape that fits into the dust suction head mounting portion 3 of the dust suction body 2, and a large number of protrusions are provided on the front side of the base 6 in an appropriate distribution as shown in FIG. The suction tube 8 is attached to each of the mounting nozzles 7, and the brush 15 is disposed between the many suction tubes 8. The outer peripheral portion of the base 6 has a fitting edge 6'having an appropriate height, and the outer peripheral surface of the fitting edge 6'is fitted and fixed (generally bonded to the dust collecting head mounting portion 3 of the dust collecting body 2). It is fixed with a drug etc.). The mounting nozzles 7 projectingly distributed on the surface of the base 6 are formed with stepped holes 7a so that one end of the suction tube 8 can be fitted therein. The suction tube 8 is a tube formed of a flexible material, for example, soft vinyl chloride resin, preferably a spiral rib 8a is integrally formed on the outer peripheral surface so that the tube is not crushed by negative pressure due to suction. The one used is used. The suction tube 8 has such a length that it can spread in any direction and bend when pressed against the surface to be cleaned.

Then, a flexible tube 15 ′ shorter than the length of the suction tube 8 is attached to at least one location (three locations in this specific example), preferably in the center of the arrangement portion of the many suction tubes 8. A brush 15 in which a brush is planted is provided at the tip of the tube 15 '.

The ring brush 10 is suitable for the mounting ring portion 11 and a mounting ring portion 11 that is detachably mounted by externally fitting a base portion to the outer peripheral edge portion of the dust suction body 2 to which the dust suction head 5 is mounted. And the brushes 12 that are planted at a pitch. The base of the brush 12 is fixed by an adhesive at the planting hole of the mounting ring 11, and the total length of the brush 12 is longer than the upright length of the suction tube 8 during assembly. Further, a step portion 11a is provided inside the mounting ring portion 11, and locking claws 13 are provided at a plurality of locations on the inner side surface thereof, and the locking claws are provided at the engaging portion 3a provided on the outer peripheral surface of the dust suction body 2. The step portion 11a is engaged with and fixed to the shoulder portion of the dust suction main body 2 when being fitted and attached with 13 being engaged and disengageable with respect to the shoulder portion of the dust suction main body 2. The brush 12 is, for example, a nylon monofilament. Of course, animal hair may also be used.

The dust collecting tool 1 of the present invention configured as described above is used by inserting the connecting port 2'of the dust collecting body 2 into the tip of the suction rod of an electric vacuum cleaner (not shown) as in the conventional dust collecting attachment. To be done. When using it, the dust suction head 5 is pressed against the surface to be cleaned and moved according to the state of the other party, as shown in FIG. Then, the brush 12 of the ring brush 10 is arranged around the dust suction head 5 and the inner suction tube 8 surrounded by the brush 12 bends freely, so that the suction tubes 8 are spread in all directions and opened at the tip. The portion faces the surface to be cleaned. Therefore, when the dust suction tool 1 is moved in that state, the brush 12 of the ring brush 10 arranged around the dust suction device causes the dust adhering to the surface to be cleaned to be aspirated, and the dust thus aspirated causes It is sucked into the dust collecting main body 2 through the opening of the tube 8 and collected in a dust collecting chamber (not shown) in the vacuum cleaner.

Since the dust collector 1 of the present invention absorbs dust as described above, the suction ports of the suction tubes 8 of the dust suction head 5 can be individually turned and moved with respect to the surface to be cleaned. For example, even when cleaning a grooved portion or a partially protruding portion, each suction tube 8 can be freely displaced in accordance with the shape of the surface to be cleaned to suck and remove dust. Moreover, when the dust suction tool 1 is moved along the surface to be cleaned, dust adhering to the portion rubbed by the brush 12 of the ring brush 10 is scratched and simultaneously sucked from the opening of each suction tube 8. Moreover, since the suction tubes 8 have a small diameter, the suction speed is fast, and the scratched dust is quickly sucked and removed. Further, the brush 15 located between the large number of suction tubes 8 scrapes off the dust inside the ring brush 10 and is useful for accelerating the dust removal operation.

As described above, the large number of suction tubes 8 are pressed against the surface to be cleaned and bent in four directions. When the pressing force is released, the suction tube 8 is restored to its original straight state by its own restoring force. Therefore, when it is used next time, it can be bent again in any direction to freely absorb dust. Further, since the ring brush 10 has the mounting ring portion 11 which is attachable to and detachable from the dust suction main body 2, the ring brush 10 and the dust suction main body 2 and the dust suction head 5 as a whole can be easily cleaned. It can be carried out. The ring brush 10 has a step portion 11a formed inside the mounting ring portion 11 with respect to an engaging portion 3a provided on the outer peripheral edge portion 2 "of the dust suction main body 2 and engaged with the shoulder portion of the dust suction main body 2. Since it is mounted by the engagement of the locking claws 13, a mounting and holding force is obtained, and it is stable without falling off during dust collection operation.

Further, according to the present invention, the dust collecting brush 16 made of a highly electrostatically-charged fiber (acrylic fiber, nylon fiber, etc.) is disposed in the plurality of suction tubes 8 of the dust suction head 5 described above. It can be provided instead of the brush 15. In this way, if the dust collecting brush 16 equipped with a brush made of highly electrostatically charged fibers is incorporated, dust in the vicinity is attracted to the dust collecting brush 16 by pressing it against the surface to be cleaned and rubbing it. The dust collection effect can be enhanced. Since dust adheres to and remains on the dust collecting brush 16 after cleaning, it is desirable that the dust collecting brush 16 be detachable from the mounting portion so that the dust can be removed separately.

The dust collector 1 of the present invention is not limited to the above-described overall shape, and may have any shape without impairing the gist thereof.
