On the other hand, the connecting cord 3 is the first connector 31 that is electrically connected to the concave connector 14 of the electric device body 1.
And a second connector electrically connected to the convex connector 25 of the charger 2.
Connector 32 and a cord portion of a predetermined length for conducting these
It is composed of 33 and.

The first connector 31 is electrically connected to a first casing 34 formed in a generally rectangular shape so as to be fitted in the concave portion 15 and a plug portion 16 provided inside the first casing 34. And a hole 36 into which the plug lever 18 is loosely inserted. The second connector 32 is
It is composed of a second casing 37 formed in a concave shape so as to be fitted to the convex portion 26, and a plug portion 38 electrically connected to the plug receiving portion 27 provided inside the second casing 37. .

Next, the charging method of this embodiment will be described. In this embodiment, there are two cases of charging the electric device body 1 with the charger 2, a case where the connection cord 3 is not used and a case where the connection cord 3 is used.

First, when the connection cord 3 is not used, as shown in FIG.
The concave connector 14 is connected to the convex connector 25 as shown in FIG. At this time, the plug portion 16 is connected to the plug receiving portion 27, and the switch portion is closed because the plug lever 18 is pushed up by the push-up rib 28.

Therefore, even if the switch handle 13 is operated, power cannot be supplied from the portion to be charged to the drive portion, the DC power DC is supplied from the charging portion 24 to the portion to be charged, and the portion to be charged is charged. To go. When the charging unit 24 outputs the DC power supply DC and a certain period of time elapses, the supply of the DC power supply DC to the charged unit is stopped, and the charging of the charged unit is completed.

Next, when the connection cord 3 is used, the first connector 31 is connected to the concave connector 14 as shown in FIG. 3, and the second connector 32 is connected to the convex connector 25 as shown in FIG. Connect to. At this time, the plug section 16 is the plug receiving section.
It will be in the state of being connected to 35 and the switch part will be the plug lever
Since 18 is loosely inserted in the hole 36, it is in an open state.

Therefore, when the switch handle 13 is operated, power can be supplied from the charged portion or the charging portion 24 to the driving portion. That is, when the switch handle 13 is in the OFF state, the charging unit 24 supplies the DC power supply DC to the charging target portion for a certain period of time to charge the charging target portion. When the switch handle 13 is in the ON state, the charging unit 24 supplies the DC power supply DC to the drive unit, and the drive unit is driven. The DC power supply DC supplied to the part to be charged and the drive part is
The size is approximately constant.

As described above, according to the present embodiment, when the electric equipment body 1 is detached from the charger 2 and the connection cord 3, the driven portion of the electric equipment body 1 can be driven by the charged portion.
In addition, when the electric device body 1 and the charger 2 are electrically connected with the connection cord 3, there is a risk of electric shock, etc., with a sufficient distance between the electric device body 1 and the charger 2. Since the charged portion 24 can charge the portion to be charged and the driving portion can be driven with almost no battery, as a result, it can be used as a waterproof type in addition to being used as a non-waterproof type.

Further, in this embodiment, when the electric equipment body 1 is directly connected to the charger 2, the switch portion is closed and the driving portion cannot be driven, and the electric equipment body 1 and the charger 2 are not driven.
When and are connected with the connection cord 3, as well as the electrical equipment
When 1 is disconnected from the charger 2 and the connection cord 3, the switch part is opened and the drive part can be driven, and the electric device main body 1 can be moved appropriately independently of the charger 2. It is easy to use.

Further, in this embodiment, since the plug switch 17 operates together by connecting and disconnecting the concave connector 14 and the convex connector 25, the plug switch 17 can be reliably operated.

In addition, this embodiment is based on the existing electric equipment main body 1
This can be easily realized by using the charger 2 and the charger 2 and adding the connection cord 3.

In this embodiment, the electric device body 1 is a reciprocating electric razor, but other devices may be used.

[0034]

The rechargeable electric device according to claim 1 has a sufficient distance between the electric device main body and the charger when the connection cord is provided between the electric device main body and the charger. In addition, since the charging part can charge the charged part or drive the driving part with almost no danger of electric shock, as a result, it can be used not only as a non-waterproof type but also as a waterproof type. be able to. Further, when the main body of the electric device is detached from the charger and the connection cord, the drive part of the main body of the electric device can be driven by the part to be charged.

In addition to the effect of claim 1, the rechargeable electric device according to claim 2 cannot drive the drive unit when the electric device main body is directly connected to the charger, so that the electric device main body and the charger are separated from each other. When a connection cord is provided between them and when the main body of the electric device is detached from the charger and the connection cord, the drive unit can be driven and the main body of the electric device can be moved independently from the charger, which is convenient. You can get better.

According to the rechargeable electric device of the third aspect, in addition to the effect of the second aspect, the switching means can be operated more reliably.
