Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a floor nozzle for a vacuum cleaner used in general households.

BACKGROUND OF THE INVENTION Conventionally, this type of seed bed nozzle has generally had a configuration as shown in Japanese Patent Publication No. 59-52548. The configuration will be explained below with reference to the drawings.

In FIG. 4, a joint 1 communicating with the suction side of the vacuum cleaner is connected to a nozzle body 3 consisting of an upper nozzle member 2a and a lower nozzle member 2b. Reference numeral 4 designates a brush holder that holds the brush body 6 and moves it up and down, and 6 designates a suction port that sucks in dust on the carpet or floor surface by suction force.

Problems to be Solved by the Invention In such a conventional floor nozzle of a vacuum cleaner, when cleaning the floor, the brush body 5 is made to protrude downward to sweep over the floor without damaging the floor. It has a sweeping action, and when cleaning the carpet, the brush body 6 is stored inside,
I try not to dig into the carpet hair. However, with this product, when cleaning a carpet, fibrous dust such as lint on the same carpet is removed by the suction force and the brush body 5.
Only slight scraping of the dust could not sufficiently capture the dust, and therefore a lot of dust remained on the carpet, resulting in insufficient performance. Furthermore, there is a problem in that the thread waste caught on the brush body 5 remains attached to the brush body 5 without being sucked up, resulting in a very unsanitary situation.

The present invention solves these problems and provides a floor nozzle for a vacuum cleaner that can reliably capture dust such as lint.

Means to Solve the Problems In order to solve the above problems, the present invention aims to provide a suction port at the bottom of the floor nozzle body, which is provided with a joint for connection to the vacuum cleaner side, and a dust collector located separately from the suction port. The suction port and the dust collecting part are connected to the joint, and the dust collecting part has a raised brush on its circumferential surface, and the dust collecting part has a raised brush on its circumferential surface, and the dust collecting part has a raised brush on its circumferential surface. This rotor is provided with a rotor that rotates reversely in conjunction with the rotor, and a scraping plate that scrapes off dust such as thread waste captured by the brush of the rotor in conjunction with the reverse rotation of the rotor.

Function The present invention is provided with a dust collecting section as described above, and this dust collecting section is provided with a rotor having a brushed brush on its circumference and a scraping plate for scraping off dust attached to the brushed brush. During cleaning, lint and the like are captured by this raised brush, and further separated from the same brush by a scraping plate and sucked.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 11 denotes a floor nozzle body constructed by connecting an upper nozzle member 12 and a lower nozzle member 13 via a bumper 14, and the rear central part thereof is formed circularly to form a joint 16. It is rotatably arranged in the cylindrical portion 18.

17 is a roller disposed below the joint 16. Further, the lower nozzle member 13 of the floor nozzle body 11 has a dust suction section 20 consisting of a suction port 18 and a suction groove 19 extending left and right from the suction port and having an open outer end.
A slit-shaped opening 21 is formed parallel to o and located before and after it.

A pair of brush bodies 22 and a brush adjusting body 23 for vertically moving the brush bodies 22 are provided within the floor nozzle body 11.

The brush body 22 has a structure in which brushes 25 are installed in a bundle on a brush holder 24, and guide holes 2e formed at both ends of each brush holder 24 are fitted into posts 27 protruding from the upper nozzle member 12. It is held so that it can move up and down.

As the brush 25 moves up and down, the slit-shaped opening 2
1 and protrudes below the floor nozzle main body 11.

28 is a lever of the brush adjustment body 23, which is a lever of the brush adjustment body 23;
It faces outward from the window hole 29.

Further, a dust collecting section 30 is provided behind the suction port 18 and is spaced apart from the suction port 18 . Inside this dust collecting part 3Q, there is a rotor 31 that can rotate freely and a scraping plate 32 that can freely move back and forth.
A raised brush 33 and a raised brush 34 are installed in corresponding parts of the rotor 31 and the scraping plate 32.

Here, the raised brush 33 of one rotor 31 is set in an inclined shape so that its tip is located diagonally backward, and the raised brush 34 of the other scraping plate 32 is set in an inclined shape so that its toe is located diagonally upward. Further, the rotor 31 is provided with a protrusion 36 for preventing rotation, and the scraping plate 32 is provided with a spring (not shown) for biasing it toward the rotor 31.

The suction port 18 and the joint 16 communicate with each other through a ventilation path 36 formed by the upper nozzle member 12 and a partition wall 37. Further, a shielding plate 38 is provided from the rear of the brush adjustment body 23 and slides on the partition wall 37, and the partition wall 37 and the shielding plate 38 are provided with an opening 39 and an opening 4o, respectively. Then, only when the lever 28 is slid toward the centermost side of the floor nozzle body, the opening 39 and the opening 4o match, and the auxiliary passage 41 that communicates the dust collecting section 3o and the ventilation passage 3e is set. I have to. To explain the operation in the above configuration, the protrusion of the brush 26 of the brush body 22 is adjusted according to the condition of the surface to be cleaned. For example, when the surface to be cleaned is a carpet, it is in the retracted state, When it is desired to obtain a strong suction force on the surface to be cleaned, such as, the suction force is set to a medium level, and when a weak suction force is desired to be obtained, the force is set to the maximum force.

Such adjustment of the protrusion of the brush 25 is performed by sliding the brush adjustment body 23 left and right via the lever 28 and moving the brush body 22 up and down along its cam groove (not shown). be.

Dust from the floor or tatami surface flows into the floor nozzle main body 11 via the suction port 18 and the suction groove 19 extending left and right from the suction port 18, and then flows from the joint 15 to the vacuum cleaner.

By the way, when cleaning the carpet, use lever 2.
8 to the centermost side (that is, the brush 25 is raised to the top).

At this time, the opening 4 of the shielding plate 38 in the brush adjustment body 23
o and the opening 39 of the partition wall 37 are aligned to form an auxiliary passage 41 that communicates the dust collecting section 30 and the ventilation passage 36. Therefore, fiber dust such as thread waste captured by the dust collecting section 30 is vigorously sucked into the ventilation path 36.

Next, the situation in which thread waste is captured in the dust collecting section 30 will be explained.

When pulling back the floor nozzle body 11, the rotor 3
1, the protrusion 36 wraps around the carpet and rotates forward, and the raised brush 33 is exposed on the carpet surface as shown in FIG. being captured. Then the floor nozzle body 1
1 is pushed forward, the rotor 31 rotates backward via the protrusion 36, and the raised brush 33 enters inside.
It faces the raised brush 34 of the scraping plate 32. Furthermore, when the floor nozzle main body 11 is retreated, the rotor 31 rotates forward again via the protrusion 36, and at this time, the lint from the nap brush 33 is scraped off by the nap brush 34. However, the nap brush 33 exposed on the carpet surface There is no lint left behind, and the dust can be collected in a fresh state.Furthermore, the lint adhering to the raised brush 34 is forcefully sucked into the ventilation passage 36 by the suction force, and a lot of dust is left in the dust collecting part 3o. It doesn't get stuck. In addition, when the airflow flows from the dust collection part 3o, the suction port 1
8, the amount of dust flowing is reduced, but the amount of leakage from the dust collection section 3o is not necessary to the extent that it affects the dust collection performance, and by providing the dust collection section 30, the thread waste collection performance is improved as a whole. It becomes very easy to use.

In addition, in the above embodiment, as a specific means for reversing and rotating the rotor, a protrusion was provided from the surface thereof, but in addition to this, the roller 17 and the rotor may be linked via a transmission means such as a belt. In short, as long as the rotor rotates in reverse in conjunction with the forward and backward movement of the floor nozzle body, there is no restriction on the means used.

As described in detail of the invention, the floor nozzle of the vacuum cleaner of the present invention has a dust collecting section separated from the suction port, and this dust collecting section has a reversible rotor equipped with a brushed brush and a brushed brush. Since a dust scraping plate is installed from the brush, not only normal dust but also lint etc. can be properly sucked in when cleaning the carpet.This ensures high surface dust collection performance, and its structure is designed to remove dust. It can be constructed simply by providing a collection section.
