When the 253 is connected, the switching protrusion 157 is formed in the second charging terminal body 251 to penetrate. Here, the switching protrusion 157 and the through groove 257 also serves to guide the coupling of the first charging terminal body 151 and the second charging terminal body 251.

The connection of the filling device of the vacuum cleaner according to the present invention configured as described above will be described with reference to the accompanying drawings.

As shown in FIG. 5, when the vacuum cleaner body 200 is seated on the seating portion 115 of the charging station 100, the first charging terminal body 151 is inserted into the second charging terminal body 251. The first terminal 153 and the second terminal 253 are in contact with each other. As a result, a commercial external power source connected to the first terminal 153 is connected to the second terminal 253.

In this case, the switching protrusion 157 protruding from the first charging terminal body 151 is inserted into the through hole 257 of the second charging terminal body 251. Accordingly, the front end portion of the switching protrusion 157 penetrates the through groove 257 so that the push button 310 of the control switch 300 is pressed. As the push button 310 is pressed in this way, the first conductive wire 320 and the second conductive wire 330 are electrically connected in the intermittent switch 300, and the charge applied to the second terminal 253 is applied to the rechargeable battery. The rechargeable battery is charged.

On the contrary, when the vacuum cleaner main body 200 is separated from the charging station 100, the first conducting wire 320 is released as the pressing force released by the switching protrusion 157 applied to the push button 310 by the switching protrusion 157. ) And the second conductor 330 are disconnected. It is preferable that the push button 310 is elastically biased in the direction of the second charging terminal body 251 by a predetermined elastic body (not shown) so that the push button 310 is smoothly returned to the original position. As such, when the connection between the first conductive wire 320 and the second conductive wire 330 is broken, not only does it suppress the natural discharge through the second terminal 253 exposed to the air, but also a vacuum. It is possible to suppress the occurrence of a safety accident due to contact between the user and the second terminal 253 during cleaning using the cleaner body.

According to the present invention configured as described above, it is not necessary to use a separate fastening member to mount the first charging terminal unit in the charging station. Accordingly, the manufacturing process can be simplified and the manufacturing cost can be reduced.

And it is provided with a charging intermittent means for controlling the connection between the second terminal and the rechargeable battery by detecting the connection between the first charging terminal portion and the second charging terminal portion. Accordingly, the inconvenience of having to charge the rechargeable battery frequently can be eliminated by suppressing the discharge of the charge of the rechargeable battery through the second terminal exposed to the air.

In addition, since the first and second terminals are prevented from being contacted with each other by the charge interrupting means, there is an effect of suppressing occurrence of a safety accident.

As described above, the present invention has been illustrated and described with respect to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
