Description

[Detailed description of the invention] The present invention relates to an improved structure of a floor suction tool that uses a rotating brush body to scrape out and suck out dirt hidden deep inside carpets, etc. The purpose of this is to prevent the rotary brush body from getting caught in the end of the body and causing malfunction of the rotating brush body.

Conventionally, this type of floor suction tool has a flange portion 23 provided at the end of the rotating brush body 6, as shown in FIG.
Furthermore, a structure is adopted in which a cover 25 is provided to cover this flange portion. However, in such a structure, there must be a gap between the flange part 23 and the cover 25, and if thread waste gets into the gap, the flange part 23 and the cover 25
A lock occurs between. Further, fine dust enters the space between the bearing metal portion 7 and the cover 25 and accumulates therein, resulting in the disadvantage that the rotation of the rotating brush body 6 becomes heavy and becomes locked.

The present invention provides a floor suction device in which a rotary brush body that is rotationally driven by an electric motor or a turbine is disposed at the front suction port of the suction device body, in which a rotary brush body is provided at both ends of the rotary brush body outwardly in the axial direction. By integrally forming a conical inclined surface that expands in the direction and a large diameter flange continuous to the inclined surface, it is possible to prevent thread waste from being caught in the bearing metal part and the resulting rotational failure of the rotating brush body. This is what I did.

The present invention will be described below with reference to embodiments shown in the drawings.

Reference numeral 1 denotes a main body case with an open bottom surface, and inside the case there is a horizontally elongated suction chamber 3 at the front, a belt storage chamber 4 at the side, and an electric motor storage chamber 5 adjacent to the belt storage chamber. It is sectioned. Reference numeral 6 denotes a rotary brush body rotatably disposed in the horizontally elongated suction chamber 3 via bearing metal parts 7, 7, and a brush 8 and a batter 9 are formed in a spiral shape. Reference numeral 10 denotes a motor disposed in the motor storage chamber 5, and a rotating shaft 11 of the motor and a rotating shaft 12 of the rotating brush body 6 equipped with a pulley (not shown) both protrude into the belt storage chamber 4, and both are connected to the belt 13. are connected by A connecting pipe (not shown) provided at the center of the horizontally elongated suction chamber 3 and the rear part of the main body case 1 is connected by a flexible passage 14. Reference numerals 15 and 15 denote a pair of moving wheels, which are attached to the rear part of the main body case 1 via an axle 16. Reference numerals 17 and 17 denote a pair of rollers disposed at the rear of the suction chamber 3, and the rollers are pivotally supported by a support shaft 19 attached by a mounting plate 18, and the degree of protrusion is adjusted by rotation of the support shaft 19. be done. A curved portion 20 is formed in the middle of the support shaft 19, and by rotating this curved portion with a rotating cam member 21, the height of the rollers 17, 17 is adjusted and arranged in the suction chamber 3. The distance between the rotating brush body 6 and the floor surface of the carpet is adjusted.

At both ends of the rotating brush body 6, there are conical inclined surfaces 22, 22 that expand outward in the axial direction.
and a large diameter flange portion 23, 2 continuous to the inclined surface.
3 are integrally formed.

In addition, the lower opening of the main body case 1 has a horizontally elongated suction chamber 3.
A bottom plate (not shown) having an opening 24 through which the rotating brush body 6, rollers 17, 17, and moving wheels 15, 15 face is provided.

In the above configuration, when the electric motor 10 is driven to rotate the rotary brush body 6 and thread waste is wrapped between the flange portion 23 and the batter 9, thread waste etc. Since the yarn slides toward the batter 9 side, a gap is created between the flange portion 23 and the thread waste, making it difficult for the yarn waste to get over the flange portion 23.

Further, since the flange portion 23 has a large diameter, it becomes even more difficult for thread waste to pass over the flange portion 23. Further, the bearing metal portion 7 is open, so that fine dust does not accumulate thereon.

Since the floor suction tool according to the present invention is constructed as described above, it is possible to prevent thread waste and the like from being entangled in the bearing metal portion of the rotating brush body and the resulting malfunction of the rotating brush body.
