Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric shaver having a built-in storage battery, and more particularly to a waterproof electric shaver.

[0002]

2. Description of the Related Art A storage battery has a risk of generating hydrogen gas when it is charged. For this reason, an electric razor having a storage battery, which has a sealed body for waterproofing, is generated internally. Without a structure that can discharge hydrogen gas, there is a danger of hydrogen gas exploding when an electric spark is generated inside.

For this reason, a gas vent for releasing the hydrogen gas to the outside is required. Conventionally, the gas vent is provided near the connection with the charger at the lower end of the main body. It was

[0004]

However, since hydrogen gas is lighter than air, the generated hydrogen gas accumulates in the upper part of the main body, and is sufficiently discharged from the degassing part provided in the lower part of the main body. Can not do it. The present invention has been made in view of the above points, and an object of the present invention is to provide an electric shaver capable of reliably discharging hydrogen gas.

[0005]

According to the present invention, a switch handle is arranged on the front surface of a main body containing a storage battery,
It is a waterproof electric razor with a trimmer on the back and a connecting part to the charger at the lower end, and a gas vent hole is formed in the wall surface of the trimmer mounting upper part on the back side of the main body. It has features.

According to the present invention, since the gas vent hole is provided in the upper portion of the main body, hydrogen gas, which is lighter than air, can be discharged accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. In the figure, reference numeral 1 is a main body, and an outer blade 30 is arranged at an upper end thereof via an outer blade frame 11 and a lower end of the main body 1. A bottom cover 12 is attached to the main body 1, and a switch handle 2 is provided on the front surface of the main body 1, and a trimmer handle 4 having a trimmer blade 40 on the upper end is provided on the back surface so as to be vertically movable. In the figure, reference numeral 13 denotes a waterproof packing arranged at a joint portion between the main body 1 and the bottom cover 12, and the packing 13 integrally formed with the bottom cover 12 sticks out to the outer periphery of the main body 1 to prevent slippage. It also comes to function.

The switch handle 2 has a concave spherical surface at its lower portion and a finger hook 20 having a lock handle 21 arranged at the center thereof. Lock handle 21
When the switch handle 2 is moved upward in the state where the switch is pushed in and the lock is released, the switch cam 22 switches the contact. Inside the main body 1, a motor 5 and a pair of batteries 6,
6, a pair of driver elements 51, 52, etc. that receive the rotational output of the motor 5 via the eccentric shaft member 50 and convert it into reciprocating motion.
6 are attached to each of the driving elements 51, 5
The outer blade 3 is provided at a portion of the body 2 which projects above the main body 1.
Inner blades 53, 53 that are in sliding contact with the inner surface of 0 are attached.

The storage battery 6 has terminal pins 6 from both ends thereof.
A rubber packing 66 is attached to the lower end side (anode side) of the battery 1 and 61, and a metal and straight shaft 25 is provided between the pair of storage batteries 6 and 6. Are arranged so that they can move up and down. A shaft 25 whose lower end projects to the outside through the seal plate 14 and the bottom cover 12 has a lever 26 made of a molded product attached to the upper end thereof. When the electric razor is connected to a charger, the switch handle 2 It constitutes a plug switch lever that shuts off the switch that is opened and closed by.

The terminal pin 61 of one of the storage batteries 6 and the shaft 2
The lower surface of the bottom cover 12 from which the protrusion 5 projects is a connecting portion with the charger and is provided with an engaging portion 19 for engaging with the charger. The connecting portion is waterproofed and sealed by the sealing plate 14 formed integrally with the bottom cover 12. In this electric shaver, as shown in FIG. 1, a gas vent hole 55 is provided in the upper wall of the main body 1 on the rear side to which the trimmer handle 4 is attached, and the gas vent hole 55 allows water to pass through. A filter 56 that does not pass through is welded. Hydrogen gas, which is generated from the storage battery 6 during charging of the storage battery 6 and moves upward because it is lighter than air, is discharged to the outside through the gas vent hole 55. The fact that the internal space of the main body 1 is narrower at the upper side than at the lower side also makes this discharge smooth.

Reference numeral 80 in FIG. 4 denotes a mounting spring 8 on the main body 1 side.
The hinge plate 81, which is press-fitted and connected to the shaft 4, is rotatably supported and attached to the outer blade frame 11. Reference numeral 85 in the drawing denotes a detachable button which is engaged with the outer blade frame 11 by being biased by the spring 86.

[0012]

As described above, in the present invention, since the gas vent hole is located in the upper portion of the main body, hydrogen gas, which is lighter than air, can be discharged accurately, and an explosion caused by ignition of hydrogen gas can occur. There is no fear.
