Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suction tool for an electric vacuum cleaner having an air intake hole with flocked hair.

[0002]

[Prior Art]

 Conventionally, a suction tool of this type of vacuum cleaner has a structure as shown in FIG. The configuration will be described below with reference to the drawings. As shown in the figure, a brush portion 3 is planted on the air intake portion 2 arranged in front of the suction tool body 1, and a connection pipe 5 is connected to the connection concave and convex portion 4 on the rear side. One end of the connection pipe 5 is tapered, and the other end is formed with an uneven portion 6 for connection with the suction tool body 1. The joint surface of the suction tool body 1 and the connection pipe 5 is rotatably connected by a concave-convex fitting at a joint surface inclined at about 45 degrees.

[0003]

[Problems to be solved by the device]

 However, in the above conventional configuration, when the connection pipe 5 of the suction tool is connected to the tip pipe or the extension tube to clean the lighting fixture or the upper surface of the high place, the suction tool main body 1 is rotated by 180 degrees to brush the brush part. It is possible to change the direction of 3 by 90 degrees, but since it is facing up even though it is desired to be facing down, it was necessary to rotate the connecting pipe 5 180 degrees, which was a problem in terms of usability.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a suction tool having good operability, which can be easily performed by changing the insertion position of the gap nozzle when changing the direction of the brush portion. To do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has two rectangular connecting holes, which are orthogonal to each other, integrally provided at the rear of the suction tool body, and a pair of protrusions is provided on the inner surface of the connecting hole to form a gap nozzle. Is provided with a recess corresponding to the protrusion.

[0006]

[Action]

 In the above-mentioned configuration, when changing the direction of the brush portion, when the gap nozzle is inserted into the connection hole of the suction tool body, the protrusion fits into the concave portion, so that the mounting position of the gap nozzle can be changed.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in the drawing, a brush portion 13 is planted on the suction part 12 provided in front of the suction tool body 11, and two rectangular connecting holes 14a and 14b which are orthogonal to each other are integrally formed on the rear side of the suction tool body 11. It is provided in. A pair of protrusions 15a and 15b are provided on the inner surfaces of the connection holes 14a and 14b. The clearance nozzle 16 is provided with a recess 17 corresponding to the protrusions 15a and 15b.

As shown in FIG. 2, when the suction tool body 11 is attached to the tip of the gap nozzle 16, the protrusions 15 a and 15 b are fitted into the recess 17 of the gap nozzle 16. The direction of the brush portion 13 can be changed by changing the insertion position of the gap nozzle 16.

[0009]

[Effect of the device]

 As is apparent from the above-described embodiment, the suction device of the vacuum cleaner according to the present invention is provided with two rectangular connecting holes which are orthogonal to each other at the rear of the main body of the suction device, and has a pair of protrusions on the inner surface of the connecting hole. The gap nozzle is provided with a concave portion corresponding to the projection portion.With this configuration, when changing the direction of the brush portion, it is possible to easily by changing the insertion position of the gap nozzle, It is easy to use and its practical value is remarkable.
