[Industrial applications]

 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 bristles at its tip.

[0002]

[Prior art]

 Conventionally, as a suction attachment of this kind, there is, for example, one disclosed in Japanese Utility Model Publication No. 4-27488.

That is, in the conventional suction attachment, dust bristles for sweeping out dust or dirt are directly implanted at 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, it can be used for electric devices such as screen doors, sash rails, televisions, wood carving, etc. It is possible to suck dust and dirt from the suction pipe while sweeping out the dust and dirt that has accumulated in figurines and other complicated locations.

[0005]

[Problems to be solved by the device]

 However, if the dust and dirt collected in the place where the bristles of the suction attachment are intricately swept as described above, a large amount of electrostatic dust adheres to the bristles and the dust cannot be removed from the bristles.

Furthermore, 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 addition, there is a case where the brush bristles are caught on the body to be cleaned and come off from the main body and disappear.

Since the original function of sweeping out the dust and the dust is significantly deteriorated in the deteriorated brush bristles to which the dust is attached or damaged as described above, the person who cleans it, that is, the general user, needs to attach the suction attachment Despite the fact that the main body can be used without any damage, we have to purchase a new suction attachment simply because the brush hairs have become unusable.

In view of the above points, it is an object of the present invention to provide an improved suction attachment so that the deteriorated bristle can be easily replaced when the original function as the bristle is deteriorated. Is.

[0009]

[Means for solving the problem]

 The present invention has been made to solve such a problem, and a means for solving the problem is a suction attachment used for an electric vacuum cleaner having a plurality of suction pipes 2. The insertion tool 4 in which the brush hairs 3 are planted is detachably attached to the tip of a part of the suction tubes 2 among the plurality of suction tubes 2.

Furthermore, it is possible to provide a detachment preventing means for preventing the inadvertent detachment of the insertion tool 4 from the suction pipe 2.

As the detachment prevention means, for example, a large diameter portion 4a is formed at the lower end of the insertion tool 4, and the large diameter part 4a is inserted in the suction pipe 2 while the large diameter portion 4a is formed. There is a means of externally fitting a partially cut-out ring-shaped stopper 5 to the insertion portion of the insertion tool 4 so as to be locked to the portion 4a.

[0012]

[Action]

 The suction attachment of the electric vacuum cleaner configured as described above can suck dust and dirt from the suction pipe 2 while sweeping a complicated place with brush bristles. Then, if the brush bristles 3 deteriorate during repeated use, the brush bristles 3 become temporarily unusable, but the insertion tool 4 in which the brush bristles 3 are implanted is detachably attached to the main body 1. Therefore, the suction attachment can be used again only by replacing the insertion tool 4.

Further, since the suction attachment is provided with the separation preventing means, it is possible to prevent the suction pipe 2 of the insertion tool 4 from being accidentally separated.

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

【Example】

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

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

Furthermore, at the tip of a part of the suction pipes 2 of the plurality of suction pipes 2, brush bristles 3 are planted at the upper end and the lower end is detachably attached to the through hole 2a. A plug 4 having a large-diameter portion 4a larger than the inner diameter of the suction pipe 2 is inserted. A stopper 5 having a partially cut-away ring shape 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 on the insertion tool 4 in this manner, the large-diameter portion 4a larger than the inner diameter of the suction pipe 2 is attached to the inner surface of the suction pipe 2 as shown in FIG. Since the contact is made so as to spread out, it is possible to prevent the inadvertent removal of the insertion tool 4.

Furthermore, 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, it is possible to completely prevent unintentional departure.

When using the suction attachment having the above structure, the joint portion 1a of the attachment body 1 is attached to the end of the hose of the electric vacuum cleaner, and the dust is discharged from the through hole 2a of the suction pipe 2. Inhale and use it.

In this case, dust is adhered to or damaged by the brush hairs 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 tube 2, the insertion tool 4 is pulled out from the suction tube 2, and the insertion tool 4 in which new brush bristles 3 are implanted is inserted into the suction tube 2. And attach the stopper 5. By replacing the attachment 4 with a new one in this way, 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 portion of the insertion tool 4 is not necessarily provided at the lower end portion of the insertion tool 4 as shown in FIG. It doesn't have to be provided in one place. For example, a substantially spear shape as shown in FIG. 3 (a), a substantially saw shape as shown in FIG. 3 (b), or one provided at two or more places as shown in FIG. 3 (c), etc. Good.

Further, in the above-mentioned embodiment, as the detachment preventing means of the insertion tool 4, a means for forming the large diameter portion 4a on the insertion tool 4 and externally fitting the stopper 5 to the suction pipe 2 is adopted. The disengagement prevention means is not limited to this. For example, as shown in FIG. A means may be used in which the convex portion 4b is bored and the convex portion 4b is fitted into the hole 2b. In short, the detachment prevention means may be any means that can completely prevent the inadvertent detachment of the insertion tool 4 which is the original purpose and does not cause any 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 detachment preventing means is not provided, the detachment preventing means in the present invention is used. Is not an essential requirement of.

[0025]

[Effect of device]

 As described above, in the suction attachment according to the present invention, since the insertion tool in which the brush bristles are implanted is freely attachable to and detachable from the attachment body, when the brush bristles are deteriorated due to dust or damage. The deteriorated bristles can be replaced together with the insertion tool. Therefore, according to the present invention, the suction attachment can be reused only by replacing the deteriorated brush bristles with new brush bristles, so that 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 and insertion position of the insertion tool can be arbitrarily selected.

Further, since the insertion preventing member is fitted into the main body and is not accidentally removed during use, the insertion device having the brush bristles is known. It can be completely prevented from disappearing.
