Description

[Detailed description of the invention] This invention relates to the structure of a suction force adjustment ring for a vacuum cleaner.
The purpose is to hold the power cord of the electric floor suction device and to facilitate the operation of the ring.

In conventional vacuum cleaners, the suction force is adjusted by drilling a hole in the suction pipe and installing an adjustment ring to adjust the area of this hole in order to adjust the suction force according to the condition of the cleaning surface. There was something.

In addition, floor suction tools commonly used to clean carpet surfaces have difficulty sucking in dust that is deep inside the carpet.
There is a vacuum cleaner that uses a floor suction device with an electric rotating brush, and its power source is taken from an outlet provided in the vacuum cleaner itself.As shown in Figure 4, the power cord 10
1 is a cord stopper 104 on the extension pipe 102 and the suction pipe 103.
The hose 105 was held and wired at several locations and connected to an outlet 106 provided on the hose 105, and the hose 105 was connected to the vacuum cleaner body.

The suction force adjustment ring 107 is attached to the suction pipe 1 for easy operation.
Many of them were installed at the tip of 03.

Conventionally, as shown in FIG.
Since the cord stopper 104 and the cord stopper 104 are separately provided on the suction pipe 103, the number of parts increases, the price increases, and when using a general floor suction device, the power cord 101 may be removed from the suction pipe 103. , cord stop 104
Those that are attached to the power cord 101 are difficult to dispose of and are often lost.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a vacuum cleaner body equipped with an electric blower and a dust collector (not shown), and is movable on wheels 2.

Reference numeral 3 denotes a hose, one end of which is connected to the vacuum cleaner main body 1 and the other end connected to an extension pipe 5 via a suction pipe 4.

Reference numeral 6 denotes an electric floor suction device 6 connected to the tip of the extension tube 5. The power of this electric floor suction device 6 is taken from an outlet 7 provided in the vacuum cleaner body 1, but the power cord is not included. 8 is held by the bent pipe 9 of the floor suction device 6 and the suction force adjustment ring 10, and connects the plug 11 to the plug receiving portion 12 of the hose 3.

A conductive wire is arranged in a spiral shape in the hose 3, and one end is connected to the plug receiving part 12 and the other end is connected to the plug 13. Therefore, by connecting the plug 13 to the outlet 7, electricity is supplied to the floor suction tool 6. can be supplied.

The suction force adjustment ring 10 is made of elastic synthetic resin or the like so as to open and close the hole 15 provided in the suction pipe 4, and is fitted onto the outer periphery of the suction pipe 4. When inserted further, the inner diameter expands due to elasticity and the protrusion 14 fits into the hole 15 of the suction pipe 4.

Therefore, this suction force adjusting ring 10 does not move in the front-rear force direction, but can only rotate freely, so it will not easily slip off unless you intentionally try to remove it.

A protrusion is formed from a part of the outer periphery of the adjustment ring 10,
A U-shaped groove 16 is provided in the protrusion.

The width of the groove 16 is set smaller than the diameter of the power cord 8.

The power cord 8 is removably press-fitted into the groove 16 by utilizing its own elasticity and the elasticity of the adjustment ring 10.

In addition, since the power cord 8 can be held by the adjustment ring 10 itself, it is possible to reduce the cost by eliminating the need for separate parts, and when using a general floor suction device, it is easy to operate because only the power cord 8 needs to be removed. Moreover, there is no need to lose separate parts.

Further, when operating the adjustment ring 10, the suction force can be easily adjusted by holding the operating portion 17 formed on the outside of the substantially U-shaped groove 16 and rotating it.

In addition, if the power cord 8 is integrally formed with a ring 18 having little dimensional variation as shown in FIGS. 2 and 3, the power cord 8 can be held securely even if the outer diameter of the power cord 8 varies widely.

As described above, according to the present invention, the power cord can be held by the suction force adjustment ring, and the structure can be made inexpensive and easy to operate.

Furthermore, since the groove formed in the ring is approximately U-shaped, there is no need to remove the ring each time the power cord is attached or detached, which is very convenient.
