Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an insertion hose to be inserted into an insertion opening provided in a cleaner body, and particularly, an electrode provided on the hose is connected to a power terminal of the body. Regarding things.

<Prior Art> In some vacuum cleaners, a suction hose having a built-in electric motor is connected to a plug hose connected to a cleaner body.
This is to facilitate the cleaning of the carpet by driving a rotating brush provided at the suction port using an electric motor.
Further, there is a system in which a pressure sensor is provided at the suction port or the insertion hose, and the suction port is controlled to prevent the blower motor of the main body from rotating at high speed because the suction port sticks to the floor surface and air is not sucked.
There is also a device in which a dust sensor is provided at the suction port or the insertion hose so as to judge whether or not there is no dust, and this is displayed on the display part of the insertion hose.

Since all of these are driven by the supply of power, this power is supplied from the cleaner body to the insertion hose.

For this reason, a power supply terminal is provided on the cleaner body, electrodes are inserted and connected to the power supply terminal at the connection part of the insertion hose to the cleaner body, and the insertion hose is connected to the cleaner body by inserting it. Power is supplied to the hose.

<Problems to be Solved by the Invention> In the above-mentioned conventional technique, the power supply terminal of the cleaner body is always exposed to the outside air, and humid air or dust adheres thereto. These dusts and moisture are removed to some extent by the friction between the electrode and the power supply terminal when the insertion hose 2 is repeatedly inserted and removed from the main body 1, but only once this oxide is formed on the power supply terminal 5. In this case, the oxide film was not sufficiently broken, which caused poor contact.

<Means for Solving the Problems> In order to solve the above problems, the present invention has a main body pipe at one end that is inserted into a mounting hole provided in the cleaner body, and when the main body pipe is inserted into the mounting hole. In the plug-in hose of the electric vacuum cleaner which is mounted by inserting an electrode connected to a power supply terminal provided in the vicinity of the mounting hole into the main body pipe, and inserting the main body pipe into the mounting hole, the electrode A cleaning material having a hygroscopic property for wiping off dust and moisture of the power supply terminal is provided at the tip of the.

<Operation> The cleaning material provided at the tip of the electrode slides on the power supply terminal when the insertion hose is attached and detached, and the connection surface of the power supply terminal is cleaned. This prevents moisture and dust from adhering to the connection surface of the power supply terminal and suppresses the formation of an oxide film on the terminal surface.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a plug hose 2 showing an embodiment of the present invention.
It is a perspective view of. 2 is a front view of the suction port 3 as seen from the body 1 side, FIG. 3 is a sectional view taken along the line AA of FIG. 2, and FIG. 4 is a perspective view of the suction port 3 as seen from the body side, FIG. FIG. 4 is a front view of the electric vacuum cleaner.

As shown in the figure, an electrode 4 for connecting the plug-in hose 2 to a power source on the main body 1 side is attached to an electrode mounting plate 7 together with a cleaning material 6 for cleaning a power source terminal 5 of the main body 1. For example, the cleaning material 6 is made of a soft material such as felt. The electrode mounting plate 7 is provided on the insertion hose 2. As shown in FIG. 1, the insertion hose 2 has a body pipe 9 inserted into a mounting hole 13 of the body 1 attached to the tip of a flexible hose body 8 to cover the hose body 8 and the body pipe 9. Hose cover 10
Mounted on The electrode mounting plate 7 is attached so as to project from the hose cover 10. Also plug hose 2
A hose fixing clamp 11 for fixing the air conditioner to the suction port 3 is swingably provided, and a hose cover 10 is provided with a swing button 12 of the clamp 11.

A circular suction port 3 is formed on the front surface of the main body 1 as shown in FIG. 5, and a mounting hole 13 having a diameter smaller than that of the suction port 3 is formed in the central inner portion so that the insertion hose 2 can be inserted. Power terminal 5
As shown in FIG. 4, is attached to the suction port 3 so as to be detachable from the insertion port 15 of the mounting box 14, and the removal preventing piece 16 of the power supply terminal 5 is formed so as to project from the insertion port 15. As shown in FIG. 3, the power supply terminal 5 is arranged on the back side of the stepped portion 18 so as to correspond to the power supply terminal hole 17, and has elasticity by bending a metal plate into a J-shape. The mounting box 14 is a rectangular box body that is integrally projectingly provided on the back side of the stepped portion 18 of the suction port 3 toward the inside of the main body and has one end opened. This opening is the insertion port 15. The withdrawal prevention piece 16 is for preventing the insertion hose 2 from being pulled out in the insertion direction, and an end portion of one side wall of the mounting box 14 is projected inward of the insertion port 15.
The flat portion of the power supply terminal 5 abuts on the pull-out prevention piece 16. Fifth
As shown in the drawing, a pair of power supply terminal holes 17 for the hand switch of the insertion hose 2 are arranged in parallel, and a pair of power brush power supply terminal holes 19 are arranged in parallel on the opposite side. The mounting portion of the power brush power terminal is similar to the mounting portion of the hand switch power terminal 5.

In the above configuration, when the plug-in hose 2 is connected to the main body 1, the power supply terminal 5 has a cleaning effect of the cleaning material 6 attached to the tip of the electrode mounting plate 7, so that dust or moisture adhering to the surface thereof is removed. After being removed, the electrode 4 attached in series to the cleaning material 6 comes into contact and is electrically connected. At this time, the hose fixing clamp 11 swings and fits with the clamp fitting portion 20 of the main body 1, and the insertion hose 2 is fixed to the suction port 3.

When removing the plug-in hose 2 from the main body 1, a swing button
By pressing 12, the hose fixing clamp 11 and the clamp fitting portion 20 are disengaged, and when the insertion hose 2 is removed, the electrical connection between the electrode 4 and the power supply terminal 5 is broken, and then the power supply terminal 5 Are cleaned by the cleaning material 6. The present invention can be applied to the power terminal for the power brush, and the electrode 4
The cleaning material 6 may be at the rear end of the electrode 4 as long as it is in series.

<Effect> As described above, according to the present invention, since the cleaning material is slidably connected to the power supply terminal when the plug-in hose is attached and detached, it is possible to wipe off moisture and dust adhering to the power supply terminal, and to clean the electrode and the power supply terminal. It is possible to eliminate the poor connection with.

Also, since the moisture is wiped off with a cleaning material to prevent an oxide film from being formed on the connection surface of the power supply terminal due to the moisture, it is possible to prevent the corrosion of the power supply terminal.
Moreover, since it is not necessary to scrape off the oxide film, it is possible to prevent abrasion of the connection surface of the power supply terminal.
