〔Example〕

The structure of one embodiment of the rotating brush of the present invention will be explained with reference to FIGS. 1 to 5.

Reference numeral 1 denotes a rotating brush body, which is formed into an elongated cylindrical shape. The rotating brush main body 1 is molded into two parts with a plane passing through its central axis, that is, the rotational axis a, as a dividing plane 2. That is, this rotating brush main body 1 consists of a pair of semi-cylindrical main body members 3 joined at the dividing surface 2.

Further, on the outer peripheral surface of the rotating brush body 1, brush bristles 4 are provided protrudingly located on an extension of one diameter when viewed from the direction of the rotation axis a. Each of these brush bristles 4 is made up of a plurality of bristles 5 arranged in a row in the direction of the rotation axis a. Further, on the outer peripheral surface of the rotating brush main body 1, heater portions 6 having a chevron-shaped cross section and extending in the direction of the rotational axis a are formed protrudingly located on an extension of a diameter perpendicular to the diameter. The dividing surface 2 passes through an intermediate position between the brush bristle portion 4 and the beater portion 6 in the rotational direction.

Further, a pair of concave type 1 moving body storage portions 7 arranged in the direction of the rotation axis a are formed on each divided surface 2 of the pair of main body members 3 constituting the rotating brush main body 1. . These sliding body housing parts 7 are formed as a deep weight body housing part 8 on one side from the rotation axis a, and a shallow cutter integral housing part 9 on the other side, and this cutter integral housing part 9 is divided into two parts. It has reached the fractional shares of side 2. Then, when both main body members 3 are joined, their opposing sliding body storage parts 7 are joined, and a pair of M moving body storage parts are aligned in the rotation @a force direction with respect to the center of the rotating brush main body 1. 7 has a point-symmetrical shape. That is, the pair of weight body housing section 8 and cutter integrated housing section 9 are located on opposite sides of the rotation axis a.

Further, semi-cylindrical groove-shaped bearing portions 10 extending in the direction of the rotation axis a are formed at both ends of the divided surfaces 2 of both main body members 3 in the direction of the rotation axis a. And both main body members 3
When the bearing parts 10 are joined together, the opposing bearing parts 10 are joined to form a cylindrical hole.

Reference numeral 11 designates a pair of sliding bodies, each including a rod-shaped weight body 12;
It consists of a plate-shaped cutter unit 13 that is detachably attached to the weight body 12. That is, a substantially cylindrical holding groove 14 is formed in the weight body 12 facing the negative side thereof, and one edge of the cutter body 13 is bent into a substantially circular side surface for fitting. It is formed in the part 15,
This fitting part 15 is inserted into the holding groove 14 of the weight body 12, and the fifth
As shown in the figure, the cutter unit 13 is attached to the weight body 12 by being freely fitted from the end face thereof. Further, the edge of the integrated cutter 13 opposite to the fitting portion 15 is formed into a sharp cutting edge 16 . The thirteen moving bodies 11 are housed in the sliding body storage section 7 of the rotating brush main body 1 so as to be slidable within a predetermined range in a direction orthogonal to the rotation axis a. , the cutting edge 16ffllJ of the cutter unit 13 protrudes and retracts from the outer peripheral surface of the rotating brush body 1. Further, a pair of springs 17 are held between the weight body 12 and one surface of the weight body storage portion 8, and the sliding body 11 is always urged in the projecting direction by the springs 17.

Reference numeral 21 denotes a cap body, which includes a cylindrical part 22 whose inner diameter is approximately equal to the outer diameter of the rotating brush body 1, and this cylindrical part 2.
Formed on one end surface of 2! A disk-shaped end plate 2 with a larger diameter than
3, and an insertion hole 24 is provided in the center of this end plate 23.
are formed in appropriate quantities. Further, the outer peripheral surface of one cap body 21 is formed into a gear-shaped boob portion 25 . These cap bodies 21 are removably fitted and fixed to both ends of the rotary brush main body 1 to which both the main body members 3 are joined.

Reference numeral 26 denotes a pair of cylindrical rod-shaped shafts, the negative side of which is inserted into the rotating brush body 1 through the insertion hole 24 of the cap body 21.
The other side of the shaft 26 is positioned on the rotation axis a and protrudes from the cap body 21 in this state.

In order to assemble this rotating brush, first, place a pair of sliding bodies 11 in each sliding body storage section 7 of one main body member 3.
, the weight body 12 is placed in the weight body storage section 8, and
The cutter unit 13 is fitted into the cutter unit housing part 9 while being positioned therein. At the same time, a spring 17 is inserted between the weight body 12 and one surface of the weight body storage portion 8. Next, the other main body member 3 is joined to this main body member 3 with the dividing surfaces 2 of both members abutting and protruding. Next, a pair of cap bodies 21 are fitted and fixed to both ends of the joined main body members 3, that is, the rotating brush main body 1, respectively. Then, both main body members 3 are held in a joined state. At the same time, a pair of shafts 2G are inserted and fixed into each bearing portion 10 of the rotary brush body 1 through the insertion holes 24 of both cap bodies 21, respectively.

Further, the rotating brush can be disassembled by the reverse procedure to the above.

Next, the operation of this embodiment will be explained.

This rotating brush is used in the suction port of a vacuum cleaner, and is rotationally driven by an electric motor or a turbine rotated by suction airflow. That is, with this rotating brush facing the suction port, both shafts 26 are supported by 11%b on bearings provided inside the suction port body, and, for example, a bobbin fixed to the rotating shaft of an electric motor and the rotating brush A belt is passed around the boob portion 25 of the brush, and the rotation of an electric motor or the like is transmitted to the rotating brush.

During cleaning, as the rotary brush main body 1 rotates, the beater part 6 provided on its outer circumferential surface presses against the surface to be cleaned, such as a carpet, while the brush body 1 also provided on the outer circumferential surface presses against the surface to be cleaned, such as a carpet. The bristles 4 scrape out dust from the surface to be cleaned.

When the rotating brush body 1 is rotating in this way,
As shown in FIG. 4, within the rotating brush body 1, the weight body 12 of the sliding body 11 is deviated with respect to the rotation @a, so that the weight body 12 is affected by the centrifugal force accompanying the rotation. , it moves in a direction away from the rotation axis a against the biasing force of the spring 17. Then, the cutter unit 13 attached to the m-weight body 12 moves to the original position, and the entire cutter unit 13 is immersed into the rotating brush body 1. therefore,
The plate-shaped cutter unit 13 does not get in the way during cleaning, and its cutting edge 16 does not damage carpets or the like. Of course, the advantage of the weight body 12 is that the centrifugal force applied to the weight body 12 as it rotates is strong enough to overcome the biasing force of the spring 17 and move the weight body 12. is necessary.

Moreover, as mentioned above, in the rotating brush main body 1, 1
Two speech bodies 11 are arranged side by side in the direction of the rotation axis a, and each IF!
By making the moving body 11 protrude in a direction symmetrical about the rotation axis a, the distribution of mm in the rotating brush body 1, especially the position of the weight body 13 having a considerable lff1, becomes more symmetrical about the rotation axis a. Since they are close to each other, the balance during rotation is good, and the rotational force of the rotating brush body 1 is not impaired.

On the other hand, when the rotating brush main body 1 is stopped, the third
As shown in the figure, due to the (=I force) of the spring 11, the sliding body 1
The cutting edge 16 side of the integrated cutter 13 protrudes from the outer peripheral surface of the rotating brush body 1 by a predetermined amount. As a result, lint or hair wrapped around the outer peripheral surface of the rotating brush main body 1 during cleaning is suppressed by the cutter unit 13 and separated from the outer peripheral surface, and in some cases, the cutter unit 1
3 with sharp cutting edges 16. If lint or the like is cut off, the lint or the like can be removed by simply wiping the outer circumferential surface of the rotating brush body 1 lightly without touching it directly with your hands, that is, without getting your hands dirty. In addition, even if the lint is not cut, the lint and the like are separated outward from the outer circumferential surface of the rotating brush body 1, making it easier to pick up the lint and the like directly, compared to the case where grooves are provided on the circumferential surface of the rotating brush body 1. Alternatively, operations such as inserting scissors or the like between the lint and the outer peripheral surface to cut the lint can be performed more easily, and the lint can be removed without any effort.

Furthermore, since the rotating brush main body 1 can be kept in a clean state at all times in this way, a decrease in its rotational force is also prevented.

In addition, since the lint and the like wrapped around the rotating brush body 1 hangs on the beater part 6, the sliding body 11
must protrude outward. Of course, in order to remove lint etc. more easily, the sliding body 11
The larger the amount of protrusion, the better. For example, it is more effective if the sliding body 11 protrudes to a position farther from the rotation axis a than the tip edge of the beater portion 6. Furthermore, if lint or the like gets caught on the heater part 6 and the brush bristle part 4, the lint or the like will be closest to the outer peripheral surface of the rotating brush body 1 at an intermediate position in the direction of rotation between the two. If the sliding body 11 is made to protrude and move back and forth at an intermediate position between the beater part 6 and the brush bristle part 4 as in the embodiment, lint and the like can be more easily removed.

In addition, since the sliding body 11 is composed of a weight body 12 and a cutter unit 13 that are detachably connected, the cutter unit 13
When the cutting edge 16 of the rotary brush is worn out, the rotary brush can be disassembled, the sliding body 11 can be taken out, and only the cutter body 13 can be replaced with a new cutter body 13.

Furthermore, the rotating brush body 1 is divided into two parts, with the plane containing the rotation @a as the dividing plane 2! 61. due to main body member 3. P! Since the moving body 11 is provided, molding and assembly are facilitated.

Moreover, since the sliding body housing section 7 is located inside the rotating brush main body 1, there is no need to make the size of the sliding body large. Compared to a structure provided on the outer peripheral side of the main body 1, the strength of the rotating brush main body 1 is reduced less.

〔Effect of the invention〕

According to the present invention, the sliding body provided in the rotating brush main body so as to be slidable in a direction substantially orthogonal to the rotational axis of the rotating brush body sinks into the rotating brush main body when rotating, and rotates when not rotating. Since it has a structure that protrudes outward from the outer circumferential surface of the brush body, lint and hair that wrap around the outer circumferential surface of the rotating brush body as it rotates during cleaning can be removed by 1'! Since the moving object separates the lint from the outer circumferential surface of the rotating brush body, these lint can be easily removed, and the rotating brush body can be kept clean at all times, reducing the decrease in rotational force. Moreover, since there is no need to provide a large outward-opening groove in the rotary brush body as in the conventional case, there is no reduction in its strength.
