Description

[Detailed description of the invention] This invention relates to a suction tool for a vacuum cleaner, and its purpose is to effectively remove lint, cotton waste, and other debris entangled in carpets, etc. The aim is to provide a suction device that can.

Conventionally, the suction device of a vacuum cleaner has been designed with a lint trap installed across the entire width of the suction passage at the bottom of the suction device in order to suck up lint and cotton waste entangled in carpets, etc. Ta.

However, since the lint remover scrapes the carpet to remove lint from the carpet, there was a drawback that the suction tool was extremely difficult to operate.

As a solution to eliminate this drawback, it has been considered to provide a lint catcher only at the front of the suction passage.
Although the operation was certainly easier, there was a drawback that the lint removal performance deteriorated.

The present invention eliminates the above-mentioned drawbacks of the prior art and provides a suction tool for a vacuum cleaner that is easy to operate and has good performance.Examples of the invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a suction device body, to which a suction joint 2 is attached so as to be able to move up and down, and a rotary vibrator 3 is rotatably attached to this suction joint 2 using a retaining ring 4. .

5 is a connecting pipe formed so that the suction passage is smooth.

A carpet sled 6 has an opening 7 in the center and suction passages 8 on the left and right sides of the opening 7.

A brush 9 is provided parallel to the rear of the suction passage 8 and is fixed to the carpet sled 6.

Reference numeral 10 denotes a front rotating roller, which, together with the rear rotating roller 11, prevents the lower surface of the carpet sled 6 from coming into contact with the floor surface, etc. when cleaning the floor surface, etc., and maintains a constant distance between the floor surface, etc. and the lower surface of the carpet sled 6. The spacing is maintained.

A bumper 1 is installed around the suction tool body 1 to prevent damage to furniture, etc. even if the suction tool collides with furniture during cleaning.
2 is provided.

A lint catcher 1 is installed before and after the opening 7 in the center of the suction passage 8.
3 is provided, and this width is as shown in Figure 3.
L between the starting points of the curve 14 leading from the suction passage 8 to the opening 7
It is set to be shorter than L1 and longer than L2 between the end points.

Further, the hair of the lint catcher 13 is bent toward the opening 7 side.

With the above configuration, when cleaning, the rotary pipe 3 is connected to the cleaner body via an extension pipe, a hose, etc., and the suction tool is operated on the surface to be cleaned to suck in dirt.

When the suction tool is pushed forward, the lint catcher 13 located at the rear of the suction passage 8 sweeps the surface of the carpet, which has loose piles, towards the suction passage 8, removing lint and lint on the surface of the carpet.
I'm going to pick up the cotton waste.

When the suction tool is pulled backwards, the lint catcher 13 at the front of the suction passage 8 picks up lint and cotton waste, and at the same time, the thread taken by the lint catcher 13 at the back of the suction passage 8 is removed. Remove lint and lint from rubbing against the carpet 13
Because the hair is in the direction of removal, it remains on the carpet surface, and the suction passage 8 passes over it.

Lint and cotton lint on the surface of a carpet are usually touched by people and get entangled in the pile of the carpet, making them difficult to remove. It simply adheres to the surface and is sucked in by the suction force of the suction tool.

In the unlikely event that lint or cotton waste is not sucked in by the suction force alone and remains on the carpet surface, it will be picked up by the lint catcher 13 at the front of the suction passage 8, and will not remain on the carpet surface.

The lint remover 13 needs to sweep the surface of the carpet with its pile, and the lint remover 1 loses its grip on the carpet's pile.
If the hair texture in step 3 is reversed, it will not be effective, and if it is too strong, it will actually scratch the surface of the carpet and damage it.

According to experiments, the pile length of the lint remover 13 is 1.5 to 2.5 mm for cut pile of nylon yarn, and 5 to 2.5 mm.
35 denier had the best performance.

If it's longer or thinner than this, the hair will be weak and won't be able to do its best, and if it's too short, it won't be able to remove the lint and cotton waste that's stuck to the inside of the carpet.
If it is too thick, if strong force is applied, it will get stuck in the carpet, making it difficult to operate and damaging the carpet.

When the lint catcher 13 is elastically supported, the bristles may be long or thick because if a strong force is applied or if the bristles are held, they will escape due to their elasticity.

In addition, since the lint remover 13 clears the surface of the carpet as described above, the resistance during operation becomes large, and the suction passage 8
If the length is the same as that of , it will be too heavy to move, and if it is too short, the amount of width that can be removed in one operation will be small, so if you want to clean a large area, you will have to operate the suction tool many times.

In addition, the suction of lint is carried out once by the lint catcher 13, which then adheres to the surface of the carpet and is sucked up using the suction force. Sometimes it remains as is.

Of course, since the lint catcher 13 is located before and after the suction passage 8, the remaining lint will be picked up by the lint catcher 13 again, but at both ends where the suction force is weak, it will not be sucked in for a long time and will continue between the lint catchers 13. It will come and go.

According to the present invention, lint, cotton (
It is possible to obtain a suction device with good performance and ease of operation, and its practical value is extremely large.
