Description

[Detailed explanation of the invention] This invention relates to an electric shaver, and saves energy by charging it with a rechargeable battery that drives the drive unit and a solar battery, and even when the charging capacity is low, the charging circuit can be used. The object of the present invention is to provide an electric shaver that can be used immediately after cutting using a dry battery as a driving source.

This idea forms a storage chamber for storing rechargeable batteries and a storage chamber for storing dry batteries in the main body case, and normally the rechargeable battery is charged by a solar battery attached to the outside of the main body case, and the driving force is generated by this rechargeable battery. When the charging capacity is low, the dry cell battery can be stored in the other storage chamber to obtain driving power, and at this time, the outer circumferential surface of the dry cell battery stored in the storage chamber can be used to switch off the charging switch. The charging circuit between the solar cell and the rechargeable battery is automatically cut off by bending the contact piece.

An embodiment of this invention will be described based on the drawings. Reference numeral 1 denotes a main body case with an outer cutter case 2 attached to one end, a solar cell 3 is attached to the outer surface of the main body case 1, and a motor 4, which is a drive unit for driving the inner cutter, is housed inside. At the same time, a storage chamber 6 for storing the rechargeable battery 5 and a storage chamber 8 for storing the dry battery 7 are formed while being separated by a partition wall 9. In addition, the PC board 1 provided in the storage chamber 6
0 is provided with a charging switch 13 consisting of a fixed contact 11 and a contact piece 12 that is connected to the fixed contact 11 by its own elasticity. This charging switch 13 is connected to a charging circuit 14 between the solar cell 3 and the rechargeable battery 5, as shown in FIG. Further, the rechargeable battery 5 is connected to the motor 4 via a power switch 15 provided on the outer surface of the main body case 1. Further, a connection terminal 1 with a spring is provided on the lid 16 provided at the lower part of the storage chamber 8.
7 is attached to the motor 4, and a connection terminal 18 is provided at the bottom of the motor 4. These connection terminals 1
7 and 18 are connected to both poles of the motor 4. Furthermore, a portion of the contact piece 12 is curved so as to protrude into the storage chamber 8 from an opening 19 formed in the partition wall 9.

In such a configuration, normally the dry battery 7 is not placed in the storage chamber 8 and the contact piece 12 is
is elastically connected to the fixed contact 11, and the solar cell 3
The solar energy is converted into solar energy to charge the rechargeable battery 5, and the rechargeable battery 5 drives the motor 4 to perform shaving. This makes it possible to save energy.

If you need to shave even if the charging capacity is low, remove the lid 10 and insert it into the storage compartment 8.
Insert battery 7 into. At this time, as shown in FIG. 3, the contact piece 12 is pushed by the outer periphery of the dry battery 7 and separated from the fixed contact 11, and the charging circuit 14 is automatically cut off. Then, by closing the lid 16, the dry battery 7 is connected to the connection terminals 17, 18 and the power switch 15.
It is connected to the motor 4 via.

Since this device is configured as described above, the driving force is normally obtained from a rechargeable battery, but this rechargeable battery can be charged with solar energy to save energy, and even when the charging capacity is low. It can be powered by a dry cell battery, and when the dry cell battery is stored in the storage chamber of the main body case, the charging circuit can be automatically cut off by pressing the contact piece of the charging switch with the outer periphery of the dry cell battery. It has the following effects.
