Problems to be Solved by the Invention However, in the conventional configuration, since the suction port terminals 33 are provided on both sides of the suction port 27, it is difficult to increase the opening width of the suction port 2e at the tip (the suction port l1g). If this is not possible, and the electric suction tool 29 is removed and used, there is a problem that it is disadvantageous for cleaning a wide surface and that it is difficult to aim at the dust that is to be sucked. Ta.

In particular, rechargeable vacuum cleaners have had the problem that as one battery discharges, the suction power becomes weaker, making it impossible to clean corners, in particular.

The first object of the present invention is to solve the above-mentioned problems and to completely improve the cleaning performance by reducing the opening width of the suction port. Second
The purpose of this is to prevent deterioration of the electrical connection due to dirt adhering to the suction terminal.

Means for Solving the Problems The first technical means of the present invention for achieving the above-mentioned first object is to provide a suction port at the upper part of the inner periphery of the opening of the suction port provided at the tip of the main body and on the tip side of the suction port. forms a recess, and a suction port terminal that is electrically connected to the power supply section of the main body is arranged on the surface of this recess that crosses the suction direction, and the electric suction device side has a suction port terminal that is connected to the suction port. In this configuration, a connection terminal is disposed at a position where it is electrically connected to the suction port terminal. Further, the second technical means of the present invention for achieving the second object is that a rotating shielding plate is disposed inside the suction port to surround the suction port terminal when the electric suction tool is removed from the suction port. .

Effect: By using the first technical means described above, the opening width of the suction port can be set to be approximately the same as the outer diameter of the tip of the main body, which makes it possible to effectively clean a wide surface! - Also, it is easy to target the dust that is about to be sucked in, making it possible to reliably clean a corner.

In addition, in the second technical means, when the electric suction device is removed and used, there is a rotating shielding plate that surrounds the suction port terminal, so dust does not adhere to the suction port terminal and there is no connection between the connection terminals of the electric suction device. It is possible to provide a rechargeable vacuum cleaner that is easy to use and highly reliable without any contact failure.

EXAMPLE Hereinafter, an example of the present invention will be explained according to FIGS. 1 to 3. explain. The schematic structure of the rechargeable vacuum cleaner of the present invention will be explained with reference to FIG.

As shown in the figure, the main body 1 includes a built-in secondary battery 8, etc., which is the source of the electric blower 4wL, and a switch 6 for turning the electric blower 4 on and off is disposed above it. Further, a dust collecting section 2 is formed on the windward side of the electric blower, and the dust collecting section 2 is in communication with a suction lower that is open at its tip and projects inward. A filter 8 is freely installed inside the dust collecting section 2, and is detachably attached to the main body 1 with a buckle 91C.

Furthermore, a depressed recess 7a is formed at the upper part of the inner periphery of the opening of the suction lower and on the tip side of the suction port, and a suction port terminal 11 is disposed at the terminal UfJ10 that intersects with the suction direction of this recess 7a. , the electric suction tool 3 is.

As shown in FIG. 2, the suction vibrator 1 has an electric motor 12, a rotating brush 13 etc.

As shown in the figure, when the electric suction tool 3 is removed, the suction port terminal 1
A rotary shielding plate 1e surrounding 1 is provided. This rotation shielding plate 16 rotates around the tip of the suction port, and is always urged by a spring 17 to the state shown in FIG.

With the above configuration, the opening width of the suction lower can be set to be approximately the same as the outer diameter of the tip of the dust collection box, so that a wide surface can be effectively cleaned. In addition, it is easy to target the dust that is about to be sucked in, and it is possible to reliably clean a corner. Furthermore, when the electric suction tool 3 is removed and used, there is a rotating shielding plate 16 that surrounds the suction port terminal 11.
Dust does not adhere to the suction port terminal 11, and there is no poor contact between the connection terminals of the electric suction tool.

Effects of the Invention As described above, according to the present invention, by arranging the suction port terminal in the recess located at the upper part of the inner peripheral surface of the suction port, it is possible to connect to the terminal of an electric suction tool. When the suction tool is not in use, the opening width of the suction port can be widened until it is almost the same as the outer diameter of the tip where the suction port is installed, allowing for effective cleaning of a wide surface and removing the dust that is being sucked in. It becomes easier to aim. In addition, by providing a rotating slow-closing plate that covers the suction port terminal, dust will not adhere to the suction port terminal when the electric suction tool is removed and used, thereby preventing poor contact between the connection terminals and improving reliability. can be improved.
