[Problem to be solved by the invention]

In the conventional vacuum cleaner shown in FIGS. 18 to 20, the rotation mechanism and the electrical contact mechanism of the hose are combined with the structure and the electrical contact mechanism that are integrally formed on the hose side, resulting in damage. Moreover, when connecting or disconnecting the hose, the user must hold the rotating mechanism and the electrical contact mechanism themselves. @JA - Distortion was likely to occur and there were problems with durability.

In addition, in the conventional vacuum cleaner shown in Figures 21 and 22, the hose rotation mechanism and electrical contact mechanism are both divided into two parts, one on the hose side and the other on the main body side, so the hose can be removed from the main body. If the rotating mechanism and electrical contact mechanism
Since each mechanism is exposed, it is easy to get dirty and easily damaged.

Moreover, since the end of the electrical line on the main body side that is connected to the power source is exposed, there is a risk of electric shock to the user. The conventional vacuum cleaner shown in Figs. 21 and 22 has a problem in that the hose cannot be removed from the main body of the vacuum cleaner except for maintenance and inspection.

This invention was made to solve these problems, and has an electric line between the hose and the vacuum cleaner, the hose is detachable and can be rotated 5 times, and the hose rotation mechanism and electric contact mechanism are The purpose is to obtain a vacuum cleaner with durability.

[Means to solve the problem]

In the vacuum cleaner according to the present invention, a rotary tool is provided on the inside of the upper surface of the main body case, which communicates with the suction port and rotates integrally with the hose when the hose is connected. The operating section of the circuit and the electric motor on the cleaner body case side are electrically connected via the electrical contact mechanism of the rotating tool.

[Effect]

In the vacuum cleaner of this invention, the hose itself is detachable and rotatable, and the rotating mechanism and electrical contact mechanism are provided on the main body side, so the electric line on the main body side is not exposed, so there is no risk of electric shock. The two-rotation mechanism and electrical contact mechanism are hard to get dirty, and are hard to break or distort, so they have excellent durability.
