Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a suction port to a portable dust collector.

[0002]

2. Description of the Related Art A conventional portable dust collector will be described with reference to FIGS. Suction port 9 of a conventional portable dust collector
Has a tip portion 9a made of a synthetic resin such as plastics. Using such a portable dust collector, as shown in FIG. 5, when the dust collecting operation is performed while slightly tilting the opening of the suction port 9 and moving the body 1 back and forth, left and right, and obliquely, the tip portion 9a of the suction port 9 is obtained. Is in contact with the floor,
The floor was scratched by rubbing or hitting. Therefore, when collecting dust by moving it back and forth, left and right, and diagonally, the airframe 1 must be carefully moved so as not to damage the floor surface as much as possible.
Further, as shown in FIG. 6, when attaching the suction port 12 which is a separate accessory, when the front end portion 9a of the suction port 9 is made of synthetic resin, the front end portion 9a of the suction port 9 which is the attachment portion of the suction port 12 does not greatly expand. Therefore, suction port 1 with different mounting diameter
2 could not be mounted. That is, as shown in FIG. 7, the suction port 12 having a mounting diameter of A or more could not be mounted on a portable dust collector in which the distal end portion 9a of the suction port 9 is a synthetic resin.

[0003]

In the above portable dust collector, if the front end of the suction port is made of synthetic resin, the floor surface is easily damaged during the dust collection work. The user must carefully move the aircraft so as not to attach it, and as a result, there is a problem that the operability is very poor.

[0004] In addition, a wide variety of suction outlets are provided in the world according to the intended use, such as those sold separately from existing portable dust collectors and portable dust collectors and vacuum cleaners already owned by customers. When the suction port is attached to the suction port by diverting the suction port, if the tip of the suction port is made of a synthetic resin, there is a problem that they cannot be attached. This is because the distal end portion of the suction port, which is the mounting portion of the suction port, does not greatly expand.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable dust collector capable of solving the above-mentioned problems, improving the operability by making the floor surface less likely to be damaged during dust collection work, and attaching various kinds of suction openings. That is.

[0006]

The above object is achieved by forming the tip of the suction port with rubber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable dust collector according to the present embodiment will be described with reference to FIGS. In FIG. 1, a motor 2, a dust collecting fan 3, a switch 4, and the like are provided in a body 1. The dust collecting box 5 has a filter 6 removably housed therein, and has a suction port 9 opened forward at the tip, and is removably mounted on the body 1. Further, the tip portion 9a of the suction port 9 is formed of rubber. As the rubber, it is preferable to use, for example, natural rubber having a rubber hardness HS of about 60 ° ± 5 °. Further, the air sucked together with the dust 11 from the dust collection fan 3 directly connected to the motor 2 passes through the filter 6 from the suction port 9, passes through the dust collection fan 3, and is discharged out of the exhaust port 8. on the other hand,
The dust 11 is filtered and collected by the filter 6. The check valve 10 prevents the collected dust 11 from returning from the opening of the suction port 9 in the reverse direction.

In the portable dust collector constructed as described above, if the tip portion 9a of the suction port 9 is formed of rubber, as shown in FIGS.
Since the tip portion 9a extends along with B, as a result, A
A wide variety of inlets 12 from the size to the B size can be attached. In other words, although it is possible to push in the case of a synthetic resin as in the prior art, the suction port 9 cannot be expanded from dimension A to dimension B, and the size of the end face 12b of the suction port 12 is dimension A or smaller. It cannot be mounted unless the suction port 12 is used. However, as shown in the present embodiment, if it is rubber, it can be pushed in, or the suction port 9 can be expanded from dimension A to dimension B. Accordingly, if the size of the end face 12b of the mouthpiece 12 is the dimension B or smaller, the mouthpiece 12 can be attached.

[0009]

According to the present invention, the suction port is made of rubber, so that a variety of suction ports can be attached without damaging the floor surface during dust collection work, and the portable dust collector with excellent operability can be attached. Can be provided.
