Abstract

(57) [Abstract] [Purpose] In a gap nozzle of an electric vacuum cleaner mounted on a tip pipe, the gap nozzle can be inserted to clean even a narrow gap on the wall. A gap nozzle 5 is attached to the attachment portion 2 of the tip pipe 1, and the gap nozzle 5 is formed by using a synthetic resin material having a relatively high elasticity and a softness so that the portion a can be easily curved. . Further, in the intake portion 6, the thickness of the short side portion 7 is made smaller than the thickness of the long side portion 8 so that the intake side 6 can be easily bent easily.
A plurality of projecting ribs 9 are provided on the inner wall of the device along the intake direction so that they abut on the projecting ribs 9 when the portion b is curved. When cleaning the gap where the intake portion 6 is difficult to insert, the portion a of the gap nozzle 5 bends with a weak force,
The intake portion 6 bends to follow the gap for cleaning, and even when cleaning a gap that is slightly narrower than the intake portion 6, the short side portion 7
Is curved and narrowed, and it can be inserted into a narrow gap for cleaning.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gap nozzle of an electric vacuum cleaner mounted on a tip pipe and used.

[0002]

[Prior Art]

 Conventionally, a gap nozzle 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 gap nozzle 3 is attached to the attachment portion 2 of the front end pipe 1. The gap nozzle 3 has an air intake portion 4 having a thin tip for facilitating cleaning of a corner of a room or a gap of a closet. The intake section 4 is provided at the center of the gap nozzle 3. Since the gap nozzle 3 is frequently used, it is made small so that it can be housed in the cleaner body in consideration of usability, and is molded using a thermoplastic resin.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, since the intake portion 4 and the tip pipe 1 are formed thick and the intake portion 4 of the gap nozzle 3 is provided in the central portion, when cleaning the wall or the gap of the tans. In addition, when the gap nozzle 3 was inserted into the gap near the wall, the mounting portion 2 hits the wall, or the grip portion of the tip pipe 1 hits the wall, resulting in difficulty in operation.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a clearance nozzle that is easy to use and can be cleaned by inserting a clearance nozzle even in a narrow clearance near a wall.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a first means for solving the problems, in which the gap nozzle is formed of an elastic synthetic resin material, and the intake portion has a short-side wall thickness and a long-side wall thickness. The inner wall of the long side is made thinner, and a plurality of protruding ribs are provided on the inner wall of the long side along the intake direction. As a second means for solving the problem, another gap nozzle is mounted on the intake section of the tip pipe. In addition, as a third means for solving the problem, an attachment nozzle having a tube-shaped intake introduction portion formed of a synthetic resin material having elasticity is used as a conventional attachment nozzle. It is mounted on the tip of the gap nozzle.

[0006]

[Action]

 In the above structure, the action of the first problem solving means is that when the gap nozzle is inserted into the narrow gap, the gap nozzle bends and the projection ribs abut to secure the air passage, and the second problem. The action of the solution means is that the suction portion of the other gap nozzle is displaced in the outer peripheral direction of the mounting portion of the tip pipe, so that the grip portion of the tip pipe can be cleaned without hitting the wall, and the third problem The action of the solution is that the tube-shaped attachment nozzle can be inserted into the narrow gap to clean it.

[0007]

【Example】

 A first embodiment of the present invention will be described below with reference to FIG. In the present embodiment, the same components as those shown in the above-mentioned conventional example will be described with the same reference numerals. As shown in the figure, a gap nozzle 5 is attached to the mounting portion 2 of the tip pipe 1, and the gap nozzle 5 is formed by using a synthetic resin material having a relatively high elasticity and a softness, and the portion a can be easily curved. I am trying.

As shown in FIG. 1 (b), the intake portion 6 has a wall thickness of the short side portion 7 thinner than that of the long side portion 8 so that the intake portion 6 can be easily bent easily. Is provided with a plurality of protruding ribs 9 along the intake direction so that the protruding ribs 9 come into contact with each other when the portion b is curved.

As described above, according to the gap nozzle 5 of the embodiment, even when cleaning the gap where the intake portion 6 is difficult to insert, the portion a of the gap nozzle 5 bends with a weak force, so that the intake portion 6 does not have a gap. Can be easily cleaned by bending by following. Even when cleaning a gap that is slightly narrower than the air intake part 6, the short side part 7 is curved and the b part becomes narrower, and it is possible to insert into the narrow gap for cleaning, and the a part and the b part of the gap nozzle 5 can be cleaned. Even when curved, the protrusion ribs 9 can secure passages for air and dust.

FIG. 2 shows a second embodiment. In each drawing, the same parts as those in FIG. 1 are designated by the same reference numerals. The difference from the first embodiment is that the suction portion 6 of the gap nozzle 10 is displaced by L in the outer peripheral direction. According to this configuration, when cleaning the gap in the wall surface, the grip portion of the tip pipe 1 does not contact the wall, and the gap in the wall surface can be easily cleaned.

FIG. 3 shows a third embodiment. In the figure, the parts with the same numbers as in FIG. 4 are the same parts. The difference from the conventional example is that the gap nozzle 3 is provided with a tubular attachment nozzle 11. That is, the attachment nozzle 11 is composed of a joint portion 12, an air intake introduction portion 13 and an air intake portion 14, and the joint portion 12 is attached to the tip portion of the conventional gap nozzle 3, and the air intake introduction portion 13 has a length of about 50 to 70 cm. I have to. According to this configuration, when cleaning a narrow gap, the air intake introducing portion 13 can be inserted deep into the gap for sufficient cleaning.

[0012]

[Effect of the device]

 As is clear from the above embodiment, in the gap nozzle of the electric vacuum cleaner of the present invention, the gap nozzle is formed of a synthetic resin material having elasticity, and the intake portion has a wall thickness of the short side smaller than that of the long side. In addition to making it thinner, the inner wall of the long side is provided with multiple protruding ribs along the intake direction.With this configuration, it is possible to insert a gap nozzle even in a narrow gap near the wall for cleaning. It is easy to use and its practical value is remarkable.
