(Prior Art) Although it is not publicly known, as shown in FIG. 6 and FIG. In the case of a vacuum cleaner suction port body in which an annular brush body 4 surrounding the periphery of the vacuum cleaner is provided so as to be movable up and down,
Conventionally, a structure has been adopted in which the pivot point 5 of the rotating brush 3 and the pivot point 6 of the brush body 4 are arranged on the same vertical axis.

(Problem to be solved by the invention) However, in the above conventional structure, an extension pipe (not shown) is connected to the suction port main body 7, and the suction port main body 7 is moved back and forth by holding this extension pipe in hand to move the suction port main body 7 forward and backward. When cleaning the surface 8, when the suction port body 7 is on the front side, the position of the hand holding the extension tube is high, and the angle α between the suction port body 7 and the floor surface 8 is large, as shown in Fig. 6. Therefore, the force F・sinα acting on the floor surface 8 based on the force F pushing the extension tube increases, the bristles 9 of the brush body 4 bend, the suction port body 7 sinks, and therefore the rotating brush 3 The contact area of the brush bristles 2 with the floor surface 8 also expands and the load increases, causing the rotating brush 3 to
If the rotation of the suction port slows down or stops, and if the suction port main body 7 is advanced from the front side to the front, the position of the hand holding the extension tube will be lowered.
As shown in FIG. 7, as the angle β between the suction port body 7 and the floor surface 8 becomes smaller, the force F sin β acting on the floor surface 8 also becomes smaller, and therefore the elastic force of the bristles 9 of the brush body 4 decreases. As a result, the suction port main body 7 rises, and the contact area between the bristles 2 of the rotating brush 3 and the floor surface 8 becomes smaller or no longer in contact with each other, and the rotating brush 3 becomes almost idle.

Therefore, there was a drawback that the floor surface 8 could not be cleaned sufficiently and evenly.

The present invention attempts to eliminate the above-mentioned drawbacks.
To provide a suction port body for a vacuum cleaner in which a rotary brush rotates under any usage conditions and a surface to be cleaned such as a floor can be sufficiently and evenly cleaned.

(Function) With the suction port body of the vacuum cleaner of the present invention, during cleaning,
For example, by holding an extension pipe connected to a connecting pipe at the rear of the suction port main body, the suction port main body is moved back and forth while the brush body is grounded on a surface to be cleaned, such as a floor surface. At that time, when the suction port body is further back, the angle that the suction port body makes with the brush body and the floor surface is large, so the force acting on the floor surface based on the force pushing the extension pipe becomes large. The bristles of the brush body bend and the suction port body sinks, but since the pivot point of the brush body is located in front of the pivot point of the rotating brush, the suction port body is at the rear of the brush body. Since the rotary brush rotates in the lifting direction and moves upward, the bristles of the rotary brush do not contact the floor surface more than necessary, and the rotary brush rotates appropriately. On the other hand, when the suction port body is further forward, the angle that the suction port body makes with the brush body and floor surface is small, so the force acting on the floor surface is small, and conversely, the suction port body floats up. However, since the suction port body rotates in the direction of sinking in the rear part with respect to the brush body, and the rotating brush moves downward, the bristles of this rotating brush still come into proper contact with the floor surface.

A suction port 12 is formed on the lower surface of the suction port main body 11, and a rotary pipe 1, which is a connecting pipe, is provided on the rear side.
3 is attached so that the air sucked by the vacuum cleaner escapes from the suction port 12 into the rotary tube 13.

An annular peripheral wall 31 is provided around the suction port 12, and an annular brush body 32 surrounding the suction port 12 is provided so as to be movable up and down. This brush body 32 has brush bristles 34 implanted in an annular brush frame 33 surrounding the peripheral wall 31 so as to extend over the entire circumference and protrude downward.
The left and right sides of the suction port body 11 are rotatably supported on the left and right sides of the peripheral wall 31, which are both sides in the direction of movement of the suction port body 11, and are configured to move up and down using this as a rotation fulcrum 35. The pivot point 35 of the brush body 32 is located forward of the pivot point 21 of the rotating brush 16.

The suction port body 11 is connected to a vacuum cleaner via an extension tube or a hose (not shown) connected to the rotary tube 13 for cleaning.

The suction air from the vacuum cleaner enters through the suction port 12 and rotates the fan 14, so the rotating brush 16 rotates together with this to scrape up dirt on the floor, and the suction air sucks it up.

The above operation is carried out by holding the extension tube in the hand and pushing or pulling it from the front to the front while grounding the brush body 32 on the surface to be cleaned, for example, the floor surface.

At that time, when the suction port main body 11 is on the near side, that is, further back, the hand holding the extension tube is in a high position, and the suction port main body 11 and the brush body 3 are
2 and the floor surface, the force F・sinα acting on the floor surface based on the force F pushing the extension tube becomes large, and the bristles 34 of the brush body 32 bend, causing the suction port body 11 to bend. However, the rotational fulcrum 35 of the brush body 32 is located in front of the rotational fulcrum 21 of the rotating brush 16, and the rear part of the brush body 32 rotates about the rotational fulcrum 35 so as to rise upward. Rotating brush 16 together with suction port body 11
Since the rotating brush 16 also moves upward, the bristles 23 of the rotating brush 16 do not come into contact with the floor more than necessary and rotate appropriately.

Furthermore, when the suction port main body 11 is advanced forward from the near side, the position of the hand holding the extension tube is lowered, so that the relationship between the suction port main body 11, the brush body 32, and the floor surface is lowered, as shown in FIG. As the angle β becomes smaller, the force F·sin β acting on the floor surface also becomes smaller, and therefore, the suction port main body 11 is lifted up by the elastic force of the bristles 34 of the brush body 32. However, in this case, the suction port body 11 is rotated at its rotational fulcrum 35 with respect to the brush body 32.
Since the rear part rotates around , and the rotating brush 16 also moves downward, the bristles 23 of the rotating brush 16 properly contact the floor surface.

Therefore, no matter where the suction port main body 11 is located, the rotating brush 16 always comes into contact with the floor surface properly and evenly, so it may stop rotating if the load is too large, or it may idle if the load is too small. I don't get into a situation. As a result, dust collection by the rotating brush 16 can be ensured, and the surface to be cleaned, such as the floor, can be cleaned sufficiently, evenly, and easily.
