Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to an electric itch reliever having an extension tube incorporating a lead wire for supplying electricity to an electric suction device.

2. Description of the Related Art Conventionally, vacuum cleaners of this type have had a configuration as shown in FIG. That is, in FIG. 5, a vacuum cleaner main body 1 has an electric blower 2 built-in and a removable collection chamber 3, and two piano wires and two electric wires are installed in the dust collection chamber 3 of the vacuum cleaner main body 1. 8 in a spiral! installed hose 4
One end is detachably connected to the other end of the hose 4, one end of an extension tube 6 in which an electric wire 5 is buried is detachably connected to the other end of the hose 4, and an electric suction tool 7 is detachably attached to the other end of the extension tube 6. The vacuum cleaner main body 1, the hose 4, the extension pipe 6, and the electric suction tool 7 are electrically connected to each other. 8 is a remote switch.

Problems to be Solved by the Invention In the conventional vacuum cleaner as described above, the extension tube 6 is
Because the electric A5 is buried, the length is fixed and cannot be adjusted, and depending on the height of the user's hands, it may be too long or too short, making it difficult to use. Ta.

Furthermore, it is difficult to store a long extension tube in a closet, etc., and as a result, the vacuum cleaner cannot be stored in a narrow space, resulting in poor usability.

The present invention solves the above-mentioned problems, and aims to provide a vacuum cleaner that can freely adjust the length of the extension tube while supplying power to the electric suction tool. It is.

Means for Solving the Problems In order to solve the above-mentioned problems, the vacuum cleaner of the present invention includes a vacuum cleaner main body having an electric feed NAa and a dust collection chamber inside, and one end attached to the vacuum cleaner main body. A connected hose, and an extension pipe that removably connects the other end of the hose and an electric suction device having a garbage suction port, the extension pipe comprising:
A pipe A provided with a power rail for supplying power from the vacuum cleaner body; and a pipe A that is slidably connected to one end of the pipe A in the length direction and is connected to the pipe while being in contact with the power rail. It consists of a sliding terminal and a pipe 8 with an electric wire connected to the terminal.

Operation In the above configuration, the extension tube is fitted into the pipe A provided with the power supply rail for power supply so as to be slidable in the length direction of the pipe A, and is electrically connected by the terminal and the 7HIil. Since the vacuum cleaner is constructed of a pipe B, it can be expanded and contracted freely, and power for driving the electric suction tool, which is supplied from the vacuum cleaner body through an electric wire inside the hose, can be constantly supplied.

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

In FIG. 3, inside the vacuum cleaner body 11, an electric feeder 8 is provided.
A motor room 13 containing the a machine 12 and a dust collection chamber 15 in which a dust collection bag 14 is removably disposed are provided.

Further, the vacuum cleaner main body 11 is provided with dust in the dust collection chamber 15.
One end of a hose 16 is connected to the hose 16, and an extension pipe 17 is attached to the other end of the hose 16. An electric suction device 18 with a built-in device is removably connected thereto.

The extension v117 is wired so as to send electricity supplied from the vacuum cleaner body 11 to the electric suction device 18 from an electric wire (not shown) disposed inside the hose 16. The wiring diagram is as shown in FIG. The extension tube 17 has a structure shown in FIGS. 1 and 2. That is, the extension pipe 17 consists of a pipe A19 and a pipe 320. Two power supply rails 21 parallel to the length direction are arranged on the inner peripheral surface of the pipe A19, and the pipe 320 is connected to one end of the pipe A19. It is fitted inside and slidably connected in the length direction. In addition, the above-mentioned sliding is
It is fixed by a fixing nut 22 screwed onto the outer circumferential surface of the connecting end of the pipe A19 to the pipe 820, and a tightening ring 23 injected into the outer circumferential surface of the pipe 320.
It may be fixed by other methods. A pipe 820 is provided on the outer peripheral surface side of the end of the pipe 820 that fits into the pipe A19.
Two terminals 24 are attached that slide while constantly in contact with the power rail 21 as the terminal slides inside the pipe A19. Each of the terminals 24 has ? ! The f-line 25 is connected to supply power to the electric suction tool 18. As shown in FIG. 2, the electric wire 25 is routed through a hole 26 formed in the lengthwise direction in the pipe wall of the pipe B20.
Any method may be used, such as forming a groove or the like in the longitudinal direction of the tube wall of 0 and embedding it there. Also pipe A
Similarly, as shown in FIG. 2, the power supply rail 21 of No. 19 may have any structure as long as it can come into contact with the terminal 24, such as being partially exposed and buried in the inner peripheral surface in the length direction. .

In the vacuum cleaner described above, the extension pipe 17 interposed between the other end of the hose 16 whose one end is connected to the vacuum cleaner main body 11 and the electric suction tool 18 to connect the two is a pipe. A19 and a pipe 320 that fits inside the pipe A19 so as to vibrate in the length direction, and the pipe A19
Two parallel power supply rails 21 are arranged in the length direction on the inner peripheral surface side of the pipe B20, and the length of the pipe B20 on the inside of the pipe A19 is arranged on the outer peripheral surface side of the fitting end of the pipe B20. A terminal 24 is provided that can slide in contact with the power rail 21 as it slides in the direction, and an electric wire 25 is connected to the terminal 24.
Since the pipe A 19 and the pipe B 20 are connected to each other, the pipe A 19 and the pipe B 20 can be slid in the length direction while maintaining contact with the power supply rail 21 and the terminal 24 as necessary. The length of the extension tube 17 can be freely adjusted while constantly supplying power to the unit, making it extremely easy to use.
It is also easy to store in narrow spaces.

In the vacuum cleaner of the present invention, the extension pipes Pipe A and Pipe B are connected to the power supply rail disposed on Pipe A and pipe B.
The terminals arranged in the pipe A and Pipe 8 are held in contact so as to be able to constantly supply electrical power, and are slidable in the length direction, so the extension pipe is made by sliding the pipe A and pipe 8. Even when it is extended or retracted, the power from the cleaning grip body can be constantly supplied to the electric suction tool, so the user can adjust the extension tube to the desired length and position it for easy cleaning, making it extremely easy to use. Good quality and easy to store in small spaces.
