Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rechargeable vacuum cleaner.

BACKGROUND TECHNOLOGY Conventionally, this type of rechargeable electric vacuum cleaner has a configuration as shown in FIG.
The other end had a handle 22, and an electric blower on/off switch 23 and a charging terminal 24 were provided on the handle 22.

Problems to be Solved by the Invention However, in such a rechargeable vacuum cleaner, the electric blower on/off switch 23 can be closed in a charging state in which a charger is connected to the charging terminal. For this reason, charging occurs while the electric blower is operated, which causes adverse effects such as damage to the charger coil.

The present invention solves these conventional problems by making it impossible to close the electric blower on/off switch while charging, and making it impossible to connect the charger 3 to the charging terminal when the electric blower is operating. This provides a rechargeable vacuum cleaner.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems includes a main body that includes an electric blower and a battery as a power source, and a dust box section that includes a built-in dust collection filter. A see-saw switch for opening and closing the power supply and a charging terminal are arranged at predetermined intervals in the longitudinal direction of a part of the main body, and these switches and charging terminal are covered, and only the part facing the switch and charging terminal is left open. A switching valve is provided on the outer wall, which is slidable back and forth, and has an opening that selectively matches the opposing opening between the switch and the charging terminal on the outer wall, and furthermore, the switching valve There is a protrusion protruding from the top that turns off the seesaw switch when the charging terminal is slid open.

Effect The effect of this technical means is as follows.
In other words, by providing a sliding switch and charging terminal switching valve, it is impossible to connect a charger to the charging terminal when the electric blower is operating, and the electric blower on/off switch cannot be closed while charging. It is. This results in
It is possible to prevent the electric blower from operating in a charging state, and it is possible to prevent adverse effects such as damage to the coil of the charger.

Example Examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a rechargeable vacuum cleaner body, which has a handle part 2, a dust box part 3 is removably connected to one end, and a suction port 4 is formed at one end. There is. The rechargeable vacuum cleaner body 1 includes an electric blower 5, a battery 6 that serves as its power source, a switch 7 that opens and closes a circuit between the electric blower 5 and the battery 6, and a switch 7 that connects the battery 6 via a charger 8. It has a built-in charging terminal 9 for charging. Further, 14 is a dust collection filter provided in the dust box section 3.

Further, a sliding switch charging terminal switching valve 11 is provided between the switch 7 and the charging terminal 9 and an outer wall 10 that covers them, and an opening 12 is provided in the center thereof. The outer wall 10 is also open above the charging terminal 9.

In the above configuration, when charging, by sliding the knob 13 of the sliding switch charging terminal switching valve 11 in the direction b, the opening 12 is located above the charging terminal 9, and the charger 8 can be connected. It becomes possible. At the same time, the protrusion 13 of the switching valve 11 touches the switch 7, turning it on.
It works to convert the state to the OFF state.
On the other hand, when operating the electric blower 5, by sliding the switching valve 11 in the direction a, the protrusion 13 touches the switch, converting the OFF state to the ON state, and the upper part of the charging terminal 9 is blocked. .

In other words, the switch 7 is opened and closed by the reaction of the switching valve 11, and the upper part of the charging terminal 3 is opened and opened.

This prevents the electric blower from operating while charging, and eliminates adverse effects such as damage to the coil of the charger 8.

Effects of the invention As described above, according to the invention, it is possible to connect a charger to the charging terminal at the same time as operating the electric blower and collecting dust, thereby preventing charging. This can eliminate adverse effects such as damage to the coil.
