生の原因となっていた。In the above prior art, a horizontally long brush chamber opening toward the floor and a turbine chamber having a turbine at the rear are provided, and a suction air passage and a transmission chamber communicating with an extension pipe are provided. The rotating brushes are supported by bearings and housed rotatably, and the rotating brushes and the turbine are connected by a belt in a transmission chamber. For this reason, the suction port itself becomes large, and operability or handling is inconvenient. In addition, when performing maintenance such as removing dust, lint, and hair wrapped around the rotating brush, handling was difficult because the belt hindered removal of the rotating brush. In addition, since the turbine chamber is a suction passage for dust and the like, hair and lint are entangled with the turbine or lint collects between the blades of the turbine, thereby hindering rotation of the turbine and reducing suction performance. . Further, the structure was such that dust and the like easily adhered to the bearing portion. On the other hand, the rotation of the turbine is reduced and transmitted by a power transmission belt stretched between a small pulley provided on the shaft end of the turbine and a large pulley provided on the rotary brush. Therefore, since the turbine rotates at several times the rotation speed of the rotating brush, a speed fluctuation occurs in the flow flowing into the turbine and interferes with the turbine. Is more likely to occur. In particular, when the suction opening is separated from the cleaning surface, the rotating brush is in a no-load state, and the amount of air suction increases, so that the number of rotations of the turbine and the rotating brush increases. There was a problem of giving pleasure. In addition, when cleaning a carpet with long bristle feet, only the turbine is rotating if the rotating brush reduces resistance due to the resistance of the rotating brush, or if it becomes unable to rotate due to suction of large dust. In addition, the pulley and belt jumped, causing noise.

同じ効果が得られる。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the mouthpiece main body 1, showing a state in which an upper case is partially removed. Here, the lower case 2 has a bumper 3 for shock absorption in front and side, and a wheel 5 for movement. A bent joint 4 for putting dust from the suction port 6 on the suction airflow and sending the dust to a cleaner body (not shown) is located at the rear. A rotary brush 7 is arranged in the suction port 6, and both ends are rotatably supported by bearings 9. A turbine 10 is provided inside the bearing 9 and is connected to the rotary brush 7. On the outer periphery of the rotating brush 7, there are a base 16 having a fitting groove which is continuous in a longitudinal direction on a spiral line, and a blade 23 having a soft pliability which fits into the fitting groove. A partition 11 is provided between the rotating brush 7 and the turbine 10,
A turbine chamber 12 is formed. The lower case 2 is provided with a guide passage 14 for guiding the air passing through the turbine 10 to the bent joint 4. The removable brush cover 15 covering the rotating brush 7 and the turbine 10 has a turbine 1
An intake port 13 is opened facing the intake port 0, and a switching lever 8 for attaching and detaching to and from the intake main body 1 is provided. Although the intake port 13 is not shown, the same effect can be obtained even if it is located on the front surface of the lower case 2.

本体へ吸い込まれる。With this configuration, when the vacuum cleaner is operated to perform cleaning, air flows from the intake port 13 to the turbine 10, the guide passage 14, and the bend joint 4, causing the turbine 10 to rotate. The rotating brush 7 rotates in synchronization with the rotating force, and the surface to be cleaned is scraped up by the blades 23 of the rotating brush 7, and smoothly bends along the suction airflow from the suction port behind the rotating brush 7. 4 and is sucked into the cleaner body.

In addition, the rotation force of the turbine 10 can be prevented from being reduced, and the rotation of the rotating brush 7 can be continued to effectively absorb dust and lint adhering to the carpet. In addition, turbine 1
Since the zero intake port 13 is not in contact with the floor surface, it is possible to prevent rotation failure due to dust and lint adhering to the bearing 9 and the like of the rotating brush 7. Moreover, the turbine chamber 1
2 can reduce the gap with the outer periphery of the turbine 10, so that the efficiency of the turbine 10 is improved. Furthermore, turbine 1
Since there is no entry of hair or cotton dust, which is a factor that hinders the zero rotational force, suction performance can be maintained.

Even if the suction port main body 1 is in close contact with the floor surface, a gap through which air flows in is secured, and thus the suction port 6 is provided with a sufficient suction airflow. Therefore, the intake airflow from the intake port 13 of the turbine 10 does not rotate the turbine 7 due to its low speed. Therefore, there is no need to switch the presence or absence of rotation of the turbine 7 according to the cleaning surface, and the inconvenience during cleaning is eliminated.

The cleaning can be performed by removing the rotating brush 7 and the turbine 10. Thus, as in the conventional mouthpiece shown in FIG.
Unlike the case in which the rotary brush 18 is connected to the turbine 19 by the belt 22, no trouble is required to remove the rotating brush 18. Further, since the turbine chamber 20 located behind the rotary brush chamber is eliminated, the size of the suction main body can be reduced.

Compared to the case where the rotation speed of the turbine is greatly reduced, the speed fluctuation of the flow flowing into the turbine is less likely to occur, and the number of turbine blades *
It is possible to reduce the blade rotation noise based on the rotation speed. Even if a blade rotation sound is generated, the frequency is in a low frequency band in frequency, so that it is hard to be heard by human hearing and is solved from discomfort during cleaning. Furthermore, a belt 22 for power transmission
Since the pulley 21 and the pulley 21 are not required, tooth skipping and belt banging noise caused by a timing deviation are eliminated, so that the noise of the suction main body can be reduced.

Since the airflow flowing from the intake port 13 of the turbine 10 and the blade rotation sound and the vortex sound generated by the turbine are absorbed by the sound absorbing material 17, noise can be reduced.

いので吸込性能を維持できる。When the suction body comes into close contact with a carpet with long hairs, there is no gap between the floor and the suction air flow, and the suction airflow tends to be insufficient. Since the suction airflow can be supplemented, even if the suction port is closely attached to a carpet with long hairs, the rotation of the turbine can be prevented from decreasing. Dust can be absorbed effectively. Also,
Since the intake port of the turbine is not in contact with the floor, it is possible to prevent rotation failure due to dust and lint adhering to the bearing portion of the rotating brush. Further, since there is no entry of hair or cotton dust which is a factor that hinders the rotational force of the turbine, suction performance can be maintained.

In addition, since a power transmission belt and pulley are not required, tooth skipping and belt tapping noise caused by timing deviation are eliminated.
