Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a rechargeable electric shaver equipped with a plug block.

[Background Art] In the conventional rechargeable electric shaver A', as shown in FIG.
, an inner cutter 2 that comes into sliding contact with the inner surface of the outer cutter 1, and a drive element 1.
A vertically elongated motor 3 is connected at its upper end to one left and right end of the driver 10, and a horizontally elongated storage battery 4 is arranged with one left and right end close to and facing the upper end of the motor 3. The circuit block 5 and plug block 6 are housed below the battery 4, but the weight balance of the housed parts is not taken into account, and the motor 3, which is a heavy component, is located far away from the plug block 6. Therefore, the fifth
As shown in the figure, the charging plug blade 1 of the plug block 6 is connected to the commercial power outlet 7 placed on the wall B.
When charging by inserting the power outlet 7, there was a problem in that the power outlet 7 tilted significantly due to the looseness of the power outlet 7, making it impossible to charge efficiently.

[Object of the Invention] The present invention was made to solve the above-mentioned problem, and its purpose is to make it possible to insert the charging blade of the plug block even if the power outlet is rattled. To provide a rechargeable electric shaver that can be charged in a stable state and efficiently.

[Disclosure of the Invention] The rechargeable electric shaver of the present invention includes an outer cutter 1 in which a blade hole is formed, an inner cutter 2 that comes into sliding contact with the inner surface of the outer cutter 1,
It includes a motor 3 that drives the inner blade 2, a storage battery 4 that serves as a power source for the motor 3, a circuit block 5 that steps down the current to the storage battery 4, and a plug block 6 that connects the circuit block 5 and a commercial power source. In the rechargeable electric shaver, the charging plug blade 18 of the plug block 6 arranged at the bottom of the housing 8 as a rectangular box can freely protrude from one side of the housing 8, and connects the motor 3 and the storage battery 4. The motor 3, the storage battery 4, and the circuit block 5 are housed in the housing 8 in the order of weight from the above-mentioned one side of the housing 8, and the switch handle 16 is housed in the housing 8 except for the above-mentioned one side. It is characterized by being disposed on the other surface, and with this configuration, the above object can be achieved. That is, since the charging plug blade 18 of the plug block 6 is made to protrude from the side of the motor 3, which is a heavy component, when the charging plug blade 18 is inserted into the commercial power outlet 7, it can be kept in a stable state due to the weight of the motor 3. Moreover, since the switch handle is arranged on a different surface from the protruding side of the charging plug blade, the charging plug blade can be firmly inserted all the way into the power outlet.

The present invention will be described below based on embodiments shown in the accompanying drawings. The housing 8 is formed by engaging two halves 8a, and inside the housing 8 are a motor 3, a storage battery 4, a circuit block 5, a plug block 6, a chassis 9, a driver 10, a blade attachment/detachment button 11,
A button push-up spring 12 is housed. Further, a switch handle 16, a lamp cover 20, and a seal 21 are attached to the outer surface of the housing 8. An eccentric cam 13 and an eccentric pin 14 are provided on the output side of the motor 3.
It engages with the driver 10. The inner cutter 2 is attached to the drive bush 15 of the drive element 10 via a push-up spring and a dustproof plate 22. The outer blade frame 17 is fixed to the housing 8 by a blade attachment/detachment button 11. The outer cutter 1 having a cutter hole is attached to the outer cutter frame 17 so as to be in contact with the inner cutter. Protective caps 19 are applied to these blade blocks. A plug block 6 is located below the motor 3, which is a heavy component placed on one side of the housing 8.
can freely protrude out of the housing 8 from the motor 3 side. Next to the motor 3, a storage battery 4, which is a medium weight component, and a circuit block 5, which is a light component, are arranged in parallel. The chassis 9 connects the circuit block 5, the motor 3, and the storage battery 4 to form a circuit. Therefore, as shown in FIG. 3, when charging this rechargeable electric shaver A, with the charging plug blade 18 of the plug block 6 inserted into the commercial power outlet 7, the motor 3 and the storage battery 4 are connected from the wall surface B side. , the circuit block 5 is located, the center of gravity of the whole is close to the wall surface B, the switch handle 16 is on the front side of the housing 8, and the charging plug blade 18 is not on the protruding side. The power outlet 7 can be firmly inserted all the way into the power outlet 7, which reduces tilting.

[Effects of the Invention] According to the present invention, in the rechargeable electric shaver, the motor, the storage battery, and the circuit block are arranged in descending order of weight from the one side of the housing from which the charging plug blade of the plug block can freely protrude. The motor, storage battery, and circuit block are housed in the order in the housing, and the switch handle is located on the other side of the housing, so the plug block protruding from one side of the housing can be used for charging. When charging the plug blade by plugging it into a wall power outlet, since the switch handle is not on one side, the plug blade can be firmly inserted all the way into the wall power outlet. Although it is located at the bottom of the housing, the motor, storage battery, and circuit block placed inside the housing are arranged so that the center of gravity is closer to the one side mentioned above, so they are less likely to tilt due to weight and are stable. In addition, the plug block can be charged with a small weight load, so there is no need to worry about its strength, and it can be charged efficiently.
