Description

[Detailed Description of the Invention] The present invention relates to a floor suction tool having a main body that has a built-in rotating brush that can be raised and lowered, and is aimed at improving dust suction performance.

In conventional floor suction devices of this type, the entire suction device can be tilted up and down at the connection port, so the suction device is always constant (parallel) to the dust collection surface.
The suction performance is stable, but on the other hand, because it can be raised and raised freely, there is no pressing effect on the dust collection surface, and the entire suction tool is constantly floating and vibrating on the dust collection surface while cleaning. Therefore, the dust absorption performance was not very good.

The present invention is intended to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings. In the figure, 1 is the main body of the floor suction tool, which is combined with a cover 2 to form a box. A bumper 3 is held between the main body 1 and the cover 2. Reference numeral 4 denotes a connecting pipe, which is rotatably attached to a bearing portion 7 of a rotary pipe 6 by a retaining ring 5. The internal space surrounded by the main body 1 and the cover 2 is divided into an intake chamber 9 and an impeller chamber 10 by a partition plate 8 formed on the cover 2 and the main body 1.
Large and small suction ports 11 and 12 are provided between the suction chamber 9 and the impeller chamber 10.
The airflow passing through the impeller chamber 10 flows into the rotary pipe 6 , while the airflow passing through the small inlet 12 is configured to impinge on a turbine 13 arranged within the impeller chamber 10 . There is. The rotational force of the turbine 13 is transmitted to a gear 15 via a turbine shaft 14, and then to a gear 18 fixed to a rotating brush 17 by a belt 16. rotating brush 1
7 is held by the main body 1 via a bearing 19 and is rotatable. The rotary pipe 6 is rotatably held between the main body 1 and the cover 2, and is rotatably held by shaft portions 20 and 21 formed at the center of rotation of the rotary pipe 6. 22 is a switching lever, and by operating the switching lever 22, a blocking plate 23 formed on the switching lever 22 closes the suction port 11 and opens the suction port 12, and also opens the suction port 11 and closes the suction port. 12 can be closed. In addition, the switching lever 22 is always provided with a tension spring 2.
4 is applied, and when the switching lever 22 is operated in the right direction as shown in FIG.
It is fixed by climbing over the mountain part 27 of. At this time, the suction port 11 is closed by the blocking plate 23, and the suction port 12 is opened by the ventilation hole 28 formed in the blocking plate 23. A floor brush 29 is fixed in a groove 30 of the main body 1. A roller 31 is rotatably held at the rear of the main body 1, and a roller 32 is rotatably held at the front of the main body 1. A bearing pipe 33 rotatably holds the turbine shaft 14, and is held between the main body 1 and the cover 2. 34 is a spring whose one end is hooked to the shaft 21 of the rotary pipe 6, and the other end is fixed to a rib 35 formed on the main body 1, as shown in FIG.

In the above configuration, when suction is applied from the connecting pipe 4, airflow enters from the dust suction port 36, and the suction port 1
2 is opened by the switching lever 22, the air collides with the turbine 13 through the suction port 12 and flows toward the connecting pipe 4. At this time, the turbine 13 rotates due to the force of collision of the airflow, and the turbine shaft 1
The gear 15 rotates via the belt 16 and the gear 18, and the rotary brush 17 rotates in conjunction with the belt 16 and the gear 18. This rotation makes it easier to clean carpets, etc. In addition, the switching lever 22 allows the suction port 11
When it is open, the airflow coming in from the dust suction port 36 flows through the suction port 11, the turbine chamber 10, and the connecting pipe 4.

Next, when cleaning, place the main body 1 on the cleaning surface and slide it on the cleaning surface, the rotating pipe 6 rotates, and the main body 1 is always kept in a horizontal state with respect to the cleaning surface, and the spring 34 , for the rotating pipe 6,
The suction port 11 of the suction tool is in the direction of being pressed into contact with the cleaning surface, and is always in close contact with the cleaning surface, the brushing effect of the rotating brush 17 is reliably applied to the cleaning surface, the dust suction performance is improved, and the suction tool itself is always Since it is kept horizontally, stable dust suction performance can be obtained.

In this way, since the suction port of the floor suction tool of the present invention is always urged in the direction of being in pressure contact with the surface to be collected, stable and high dust suction performance can be obtained, which is highly effective.

In the embodiment, a coiled spring is used to bias the suction tool, but it goes without saying that a leaf spring or other elastic body may be used.
