JPH11113815A - Variable suction port - Google Patents

Abstract

PROBLEM TO BE SOLVED: To smoothly clean without troubling in detaching or exchanging a T-shaped suction port and a tapered suction port, which are in demand most out of the suction ports of a cleaner, according to the using states. SOLUTION: This suction port is provided with a slide pipe 2 in the outside of a suction pipe 1 and a side face presser part 3 in the tip end of the slide pipe 2. A rotary shaft 5 is provided in a suction port 4, enlarged suction ports 6 which set the rotary shaft 5 to the axis are provided in both sides of the suction port 4, and the enlarged suction ports 6 in both sides are connected to each other by a spring 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable suction port which can be cleaned without replacing the suction port of a vacuum cleaner.

[0002]

2. Description of the Related Art Heretofore, dust has been sucked up in a wide place by a T-shaped suction port, and dust has been sucked in a corner or a narrow place by replacing the suction port with a tapered suction port.

[0003]

This has the following disadvantages. (B) When sucking up dust at the feet of the desk or at the corner near the wall, the dust could not be absorbed unless the suction port was changed. (B) In some cases, the narrow suction port was lost or lost.

[0004]

A slide pipe (2) is provided outside the suction pipe (1), and a side holding portion (3) is provided at the tip of the slide pipe (2). Then, a rotary shaft (5) is provided in the suction port (4), and an enlarged suction port (6) around the rotary shaft (5) is provided on both sides of the suction port (4). In addition, the enlarged suction ports on both sides (6)
With a spring (7). The present invention is a variable suction port configured as described above.

[0005]

[Function] Hold the suction pipe (1) with one hand, and push forward with the other hand so that the slide pipe (2) protrudes. Then, the side holding part (3) takes a shape like pecking the enlarged suction port (6), and the enlarged suction ports (6) on both sides are pushed forward with the rotation axis (5) as an axis, and are pushed forward.
It will be in a shape that fits together. Then, it changes to a thin suction port, and dust can be sucked in from the tip suction port (8).

[0006]

Embodiments of the present invention will be described below. (A) A cylindrical slide pipe (2), which is one size larger, is provided outside the suction pipe (1), and the slide pipe (2) is provided.
A stopper contact portion (11) having a thicker edge is provided at an upper portion of the device, and a side surface pressing portion (3) for supporting a side surface from both sides is provided at a lower portion. (B) A rotary shaft (5) is provided at the suction port (4), and enlarged suction ports (6) are provided on both sides of the suction port (4) so as to bend only downward with the rotation shaft (5) as an axis. (C) A spring mounting portion (12) is provided in each of the enlarged suction ports (6) on both sides, and the two are connected so as to be pulled horizontally by a spring (7). The present invention has the above structure, and when using this,
Hold the suction pipe (1) with one hand, hold the slide pipe (2) with the other hand, and push forward so that the slide pipe (2) protrudes. Then, the projection of the tapered suction port stopper (9) comes into contact with the stopper contact part (11) and is fixed. At the same time, the side holding part (3) has a shape pecking the enlarged suction port (6), and the enlarged suction ports (6) on both sides are pushed forward with the rotation axis (5) as an axis, and the two are joined together. It looks like a shape. Then, it changes to a thin suction port, and you can suck dust from the tip suction port (8). Also,
When the slide pipe (2) is lifted up and fixed with the T-shaped suction port stopper (10), the enlarged suction port (6), which has been fitted by the force of the spring (7), springs up and sucks in dust as a T-shaped suction port. can.

[0007]

According to the present invention, when sucking up dust or dirt near a wall, in a narrow place, or at the feet of a desk, cleaning can be performed without removing or replacing the suction port. In addition, cleaning can be performed efficiently and quickly.
