[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction attachment attached to the end of a hose of an electric vacuum cleaner, and more particularly to a suction attachment having a plurality of suction pipes and brush bristles at its tip.

[0002]

2. Description of the Related Art Conventionally, as a suction attachment of this type, for example, there is one disclosed in Japanese Utility Model Publication No. 4-27488.

That is, in the conventional suction attachment, dust bristles for sweeping out dust are directly attached to the tips of a plurality of suction pipes.

If the suction attachment is attached to the end of the hose of the electric vacuum cleaner and is used while sweeping like a broom with the brush bristles, the screen door, sash rail,
It is possible to suck dust from the suction pipe while sweeping out dust and dirt accumulated in electric devices such as televisions, figurines such as wood carvings, and other complicated places having complicated shapes.

[0005]

[Problems to be Solved by the Invention] However, when dust or dirt collected in a complicated place with the brush bristles of the suction attachment is swept out as described above, a large number of electrostatically charged dusts adhere to the brush bristles. Dust cannot be removed from the bristles.

Further, since the brush bristles are swept along a complicated place having a complicated shape, the straight brush bristles are bent or broken to be damaged. In some cases, the bristles of the brush are caught on the body to be cleaned and come off from the main body and disappear.

[0007] Since the original function of sweeping out dust and dirt is remarkably deteriorated in the deteriorated brush bristles to which dust adheres or is damaged as described above, a person who cleans the hair, that is, a general user, does not use the suction attachment main body. Despite the fact that it can be used without any damage, the bristles are simply disabled and a new suction attachment has to be purchased.

In view of the above points, it is an object of the present invention to provide an improved suction attachment for easily replacing the deteriorated brush bristles when the original function of the bristles is deteriorated. Is.

[0009]

The present invention has been made to solve such a problem, and the means for solving the problem is used in an electric vacuum cleaner having a plurality of suction pipes 2. In the suction attachment, the brush bristles 3 are attached to the tips of some of the plurality of suction pipes 2.
That is, the insertion tool 4 in which is implanted is detachably attached.

Further, the insertion tool 4 from the suction tube 2
It is also possible to provide a detachment prevention means for preventing the inadvertent detachment.

As the separation preventing means, for example, a large diameter portion 4a is formed at the lower end portion of the insertion tool 4, and
A partially cut-out ring-shaped stopper 5 is externally fitted to the insertion portion of the insertion tool 4 so that the insertion tool 4 is inserted into the suction pipe 2 and is locked to the large-diameter portion 4a. There is a means to wear it.

[0012]

The suction attachment of the electric vacuum cleaner configured as described above can suck dust or dirt from the suction tube 2 while sweeping the complicated place with the brush bristles. When the brush bristles 3 deteriorate during repeated use, the brush bristles 3 are temporarily unusable, but the insertion tool 4 in which the brush bristles 3 are planted is detachably attached to the main body 1. Therefore, the suction attachment can be reused only by replacing the insertion tool 4.

Further, since the suction attachment is provided with the disengagement prevention means, it is possible to prevent the careless disengagement of the suction pipe 2 of the insertion tool 4.

Further, as the separation preventing means, a means for forming a large diameter portion 4a at the lower end portion of the insertion tool 4 and externally fitting a stopper 5 so as to be locked by the large diameter portion 4a. According to the above, the large-diameter portion 4a is in close contact with the suction pipe 2 so as to push and spread the inner surface of the suction pipe 2, and the stopper 5 is externally fitted so that the insertion tool 4 is in close contact with the inner surface of the suction pipe 2. In addition, since the large-diameter portion 4a of the insertion tool 4 is locked, accidental disengagement can be more completely prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an attachment body of a synthetic resin suction attachment having a cylindrical joint portion 1a at one end for attaching to a hose of an electric vacuum cleaner. A plurality of substantially straight cylindrical suction pipes 2 having through holes 2a for sucking dust are fixed to the other end.

Further, brush bristles 3 are planted at the upper end portion of the suction pipes 2, which are some of the plurality of suction pipes 2, and the through holes 2a are detachably attached to the lower end portion of the suction pipes 2. The insertion tool 4 in which a large-diameter portion 4a larger than the inner diameter of the suction tube 2 is formed is inserted. Further, a stopper 5 having a partially cut-away cross section is externally fitted to the outer peripheral surface of the suction pipe 2 into which the insertion tool 4 is fitted so that the large diameter portion 4a is locked.

Since the large-diameter portion 4a is formed in the insertion tool 4 as described above, the suction pipe 2 is formed as shown in FIG.
The large-diameter portion 4a, which is larger than the inner diameter of the above-mentioned, adheres so as to push and spread the inner surface of the suction pipe 2, so that the accidental detachment of the insertion tool 4 can be prevented.

Further, since the stopper 5 is externally fitted, the plug 4 is brought into close contact with the inner surface of the suction pipe 2, and the large diameter portion 4a of the plug 4 is locked. Therefore, careless separation can be more completely prevented.

When the suction attachment having the above structure is used, the joint portion 1a of the attachment body 1 is attached to the end of the hose of the electric vacuum cleaner, and the suction pipe 2 is attached.
The dust or the like is sucked from the through hole 2a of the device for use.

In this case, dust is adhered to or damaged by the brush bristles 3 during repeated use of the suction attachment, resulting in defective sweeping of dust. In such a state, the stopper 5 is removed from the suction pipe 2, the insertion tool 4 is pulled out from the suction pipe 2, and the new brush bristles 3
The insertion tool 4 in which is implanted is inserted into the suction pipe 2 and the stopper 5 is attached. By replacing with the new insertion tool 4 as described above, the suction attachment can be used as it is without being replaced.

In the above embodiment, the large diameter portion 4a larger than the inner diameter of the suction pipe 2 provided at the lower end of the insertion tool 4 is used.
Does not necessarily have to be provided at one location on the lower end of the insertion tool 4 as shown in FIG. For example, in FIG.
It may be a substantially spear-shaped one as shown in (a), a substantially saw-shaped one as shown in (b) of the figure, or one provided at two or more places as shown in (c) of the figure.

Further, in the above-mentioned embodiment, the means for preventing the detachment of the insertion tool 4 is such that the large diameter portion 4a is formed in the insertion tool 4 and the stopper 5 is externally fitted to the suction pipe 2. ,
The disengagement prevention means is not limited to this, and for example, as shown in FIG. 4, a protrusion 4b is provided at the other end of the insertion tool 4, and a hole 2b into which the protrusion 4b can be fitted is formed in the suction pipe 2. It may be a means which is provided and the convex portion 4b is fitted into the hole 2b. In short, the disengagement prevention means may be any means that can completely prevent accidental disengagement of the insertion tool 4 which is the original purpose and does not cause an obstacle when the insertion tool 4 is replaced.

However, since the suction attachment of the present invention can be used and the deteriorated brush bristles 3 can be replaced even if the separation preventing means is not provided,
The detachment prevention means is not an essential requirement of the present invention.

[0025]

As described above, in the suction attachment according to the present invention, since the insertion device having the brush bristles attached thereto is detachable from the attachment body, dust may be attached to or damaged by the bristles. If deteriorated, the deteriorated brush bristles can be replaced together with the insertion tool. Therefore, according to the present invention, since the suction attachment can be reused by simply replacing the deteriorated brush bristles with new brush bristles, the life of the suction attachment can be extended.

Further, since the insertion tool is inserted into the suction pipe for sucking dust and dirt, the user has an advantage that the number of insertion tools and the insertion position can be arbitrarily selected.

Further, since the detachment prevention means is provided, the inserter fitted to the main body does not come off accidentally during use, so that the inserter with the brush bristles is known without knowing. It can be completely prevented from disappearing.
