Description

[Detailed description of the invention] [Industrial application field] This invention relates to an electric shaver.

[Conventional technology]

Conventionally, a switch handle that can be slid vertically is disposed on the front side near the head of the housing, and a trimmer handle that has a finger-rest projection that can be operated in the same direction as the up and down operation direction of the switch handle is attached to the housing. There was an electric razor installed on the back side (for example, Utility Model No. 56-9374).

[The problem that the idea attempts to solve]

However, with this electric shaver, when operating the trimmer handle with the thumb, the index finger of the hand that grips the housing is positioned on the switch handle, so there is a problem that the switch handle may be accidentally operated incorrectly.

In addition, there was a device in which a switch stand was protruded from the surface of the housing, and the switch handle was slid onto the surface of the switch stand (Japanese Patent Application Laid-Open No. 1983-1999).
No. 29480), but because the protrusion of the switch stand is small,
It was difficult to stop my fingers from sliding around the edge of the switch stand.

Therefore, an object of this invention is to provide an electric shaver that can prevent erroneous operation of the switch handle when operating the trimmer handle, and also allows easy operation of the trimmer handle.

[Means to solve the problem]

In the electric shaver of this invention, a finger stopper is provided in the housing near the head side of the switch handle at a position below the finger rest protrusions, and this finger rest stopper is lower than the sliding surface of the switch handle. It is characterized in that it protrudes and is formed to cover the upper edge of the sliding surface.

[Effect]

According to the configuration of this invention, when the switch handle is operated, the main blade of the electric shaver is operated, and when the trimmer handle is operated, the trimmer is operated.

In this case, since the finger-holding protrusion of the trimmer handle is located above the finger-holding stopper, when operating the trimmer handle with the thumb, the index finger or the like rests comfortably on the stopper, making it easy to operate the trimmer handle. In addition, the finger stopper protrudes beyond the sliding surface of the switch handle and is formed to cover the upper edge of the sliding surface, so even if your fingers go over the finger stopper when operating the trimmer handle. It is difficult to accidentally operate the switch handle.

A switch spring 33a is formed at the other end of the conductor 32 that is electrically connected to the anode terminal pin 31 of the storage battery 8. When the switch handle 26 is operated, the switch spring 33a and the contact lug 37 come into contact, and the motor circuit 38 (the first 9) is closed and the motor 7 is driven. The switch spring 33a and the contact lug 37 constitute a switch contact portion of the switch portion 5.

The anode terminal pin 31 of the storage battery 8 also serves as the anode terminal of the charging circuit 39, and the cathode terminal of the charging circuit 39 consists of a cathode terminal pin 40a at one end of a conductive plug lever 40. Plug lever 40

1 and the cathode terminal pin 40a. The cathode terminal pin 40a is provided on the plug lever 40, and when connected to the charging adapter 42, the plug lever 40 is pushed up by the engagement protrusion 44a inside the output terminal 44. When the plug lever 40 is pushed up, the contact surface 40d contacts the plug lever contact spring 36b of the cathode terminal 36,
At the same time, the insulating protruding piece 40 of the plug lever 40
c is inserted between the contact spring 33a and the contact lug 37, resulting in a switch-off state and preventing switch-on during charging.

When the charging adapter 42 is removed, the plug lever 40 is pushed down by the lever return spring 41 provided on the plug lever 40, and the insulating protruding piece 40c is also pushed down by the plug lever contact spring 3 of the cathode terminal 36.
6b and the contact surface 40d, and the contact spring 33a and the contact lug 37 are also released. Therefore, even if the anode terminal pin 31 and the cathode terminal pin 40a are immersed in water, soap, etc. for washing or the like and become conductive, no backflow of current will occur from the battery 8. Furthermore, the conventional diode for preventing battery backflow is therefore unnecessary.

When using the outer cutter 2 and inner cutter 6 as the main cutters,
Defeat trimmer block 3. When using the trimmer block 3, the trimmer handle 4 is projected. As a result, the trimmer drive rod 3c engages with the driver 9. This makes it possible to use the switch cover 27 provided on the front side of the housing 1. At this time, as shown in FIG. Therefore, even if a force (R direction) opposite to the operating direction (Q direction) of the trimmer handle 4 is applied to the switch part 5, the index finger will not slip against the finger stopper 29 and the switch handle will not slip. There is no need to turn off the switch by lowering 26. Moreover, since the finger-rest protrusion 4a of the trimmer handle 4 is located above the finger-rest stopper 29, when operating the trimmer handle 4 with the thumb, the index finger, etc. can easily rest on the stopper, making it easier to operate the trimmer handle 4. easy.
When knocking down the trimmer block 3, operate the trimmer handle 4 in the opposite direction of the arrow Q.
Adjacent protruding portion 1a adjacent to outer cutter frame 13 of
You can receive it at Therefore, the trimmer handle 4 is stable and easy to operate.

Moreover, since the adjacent protruding portion 1a is made to protrude in the direction of inclination of the outer cutter frame, a large storage space for the driver 9 and the like in the outer cutter frame 13 can be secured. Moreover, since the finger rest stopper 29 and the adjacent protruding portion 1a protrude, the portion 1b having the recess into which the finger can be inserted is relatively thin. Since this tapered portion is near the head of the housing 1, it is located at the position of the index finger of the hand that grips the housing 1 when performing a shaving operation. Therefore, it is easy to grip and perform shaving operations. Therefore, a finger receiving function can be obtained when the trimmer handle 4 is operated to insert or remove the trimmer, and because of the adjacent protruding portion 1a that performs the finger receiving function, there is no storage space for the driving member in the outer cutter frame 13. It is possible to increase the size of the shaver and improve the ease of grip during shaving operations.

Degassing of the storage battery 8 is performed as follows.
Gas generated within the storage battery 8 is discharged from a gas vent hole 8b provided in the anode portion 8a and collected in a gas reservoir portion 8c formed inside the battery packing 35. This gas enters into the anode terminal pin 31 through a gap 8d formed between the flange portion 31a of the anode terminal pin 31 and the anode portion 8a of the storage battery 8, and is discharged to the outside of the housing 1. In this way, gas is directly discharged from the storage battery 8 to the outside of the housing 1, so unlike the conventional case where a connecting part is provided in the discharge path, gas leaks midway and fills the housing 1. disappears. Therefore, there is no problem of explosion due to ignition, and it is safe. Moreover, it can be made smaller than the conventional one in which a connecting portion is provided in the gas exhaust path.

[Effect of idea]
