Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a suction force adjusting device for a vacuum cleaner.

Conventional technology With the spread of carpet cleaners, conventional vacuum cleaners have been using electric rotating brushes to scrape up and suck in dust, since ordinary floor suction devices cannot suck up the dust deep inside the bristles. Some use a type floor suction device.

When using this suction tool, if you operate the suction power adjustment ring to lower the suction power, the hair that has been raised up will not be sucked into the main body and will often get clogged in the middle of the hose, etc. Up to now, as shown in FIG. 5, a suction force adjustment ring 101 has been provided independently, and the power cord 102 has been fixed at several locations with cord fasteners 103. Problems to be Solved by the Invention However, since the suction force adjustment ring 101 is provided independently in the above-mentioned device, it may be operated incorrectly and the hose etc. may become clogged with hair debris as described above. Further, when a normal suction tool is used instead of an electric floor suction tool, it takes time and effort to attach and detach the cords 102 by the number of cord stops 103, and furthermore, the cord stops 103 may be lost.

The present invention solves these conventional problems, and prevents the suction force from being adjusted when an electric floor suction device is in use, thereby preventing clogging of hoses, etc., and making it easier to retain the cord. It is something.

Means for Solving the Problems In order to solve these conventional problems, the present invention provides an electric floor suction device having a power cord, an extension pipe connected to the electric floor suction device, It is equipped with a hose that connects to this extension pipe, a vacuum cleaner body that has a built-in electric blower and connects the hose, and an electric power cord that connects the power cord along the extension pipe to an electrical connection provided at the end of the hose. In a vacuum cleaner, there is a cord stopper that holds the power cord of the electric floor suction tool in place along the suction pipe provided at the end of the hose, and a cord retainer that is arranged near the cord stopper. and a suction force adjustment ring that is rotatably fitted into the suction pipe and opens and closes a suction force adjustment hole provided in the suction pipe, and the suction force adjustment ring adjusts the suction force. When the adjustment hole is fully closed, the cord holding portion of the suction force adjustment ring faces the cord stopper.

Therefore, when using an electric floor suction device, the power cord held in the cord stopper may prevent the suction force adjustment ring from rotating and the suction force adjustment hole may be opened inadvertently. prevent.

Furthermore, since the suction force adjustment ring has a cord holding function, the number of cord stops can be reduced accordingly, making it easier to attach and detach the cord. EXAMPLE An example 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.

An electric floor suction port 6 is connected to the tip of the extension pipe 5.
The power for the electric floor suction device 6 is taken from the outlet 7 provided in the vacuum cleaner body 1, and the power cord 8 is held by the bent tube 9 section of the floor suction device 6 and the suction force adjustment ring 10. , connect the plug 11 to the plug receiving part 12 of the hose 3,
It is covered with a cord guide plate 13 to prevent the plug 11 from coming off easily. 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 14. Therefore, by connecting the plug 14 to the outlet 7, electricity can be supplied to the floor suction device 6. Can be supplied. The suction force adjustment ring 10 is made of elastic synthetic resin, etc., and is adapted to fit on the outer periphery of the suction pipe 4. When inserted from the tip of the suction pipe 4, the inner diameter expands due to elasticity and the protrusion 1
5 fits into the hole 16 of the intake pipe 4, and the suction force adjustment ring 1
At 0, the only movement in the front and back direction is rotation, so it will not come off easily unless you try to move it intentionally. A substantially U-shaped groove 17 is formed in a part of the outer periphery of the suction force adjustment ring 10,
By press-fitting the power cord 8, it is held by its own elasticity and the mutual elasticity of the adjustment ring 10. The cord guide plate 13 is arranged to be rotatable about a shaft portion 18 provided on the plug receiving portion 12, and serves to guide the plug 11 portion of the power cord 8 along the lower side of the suction pipe 4. As shown in FIG.
When the letter-shaped groove 17 and the cord guide part of the cord guide plate 13 are aligned, the hole 16 for adjusting the suction force is fully closed, and the suction force can be adjusted while the electric floor suction device 6 is in use. When the ring 10 is about to rotate, the end of the cord guide plate 13 is nearby and keeps the power cord 8 in the fixed position, so the elasticity of the power cord 8 returns the adjustment ring 10 to its original position and adjusts it. The opening 16 is always sealed to prevent the hose or the like from becoming clogged with dirt due to a decrease in suction power. Furthermore, since the cord guide plate 13 and the adjustment ring 10 are close to each other, the cord guide plate 13 has the effect of preventing the power supply cord 8 from separating from the adjustment ring 10. As shown in FIGS. 4 and 5, if the power cord 8 is integrally formed with a ring 19 with little variation in dimensions, the power cord 8 can be held more reliably even if the outer diameter of the power cord 8 varies widely. In addition, when you do not use the electric floor suction tool 6 and want to operate the adjustment ring 10, the groove 17
The suction force can be easily adjusted by holding and rotating the operating part 20 formed on the outside. Effects of the Invention As described above, according to the present invention, it is possible to prevent dust clogging caused by adjusting the suction force while using an electric floor suction device, and it is also possible to easily attach and detach the power cord. It has great industrial value as it is easy to manufacture.
