Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to an electric shaver with sharp edges, and particularly to a drainage mechanism of the shaving section in a flush type electric razor.

(b) Prior Art In recent years, electric shavers that can be washed with water have been on the market in response to consumer demands. Many of them have, for example, a cylindrical main body case that houses the motor and battery, which has a waterproof structure, and a finishing blade attachment or a cutting blade attachment that is removably engaged with the upper part of the case. There is no equipment that allows both attachments to be attached at the same time and operated separately, and that also allows both attachments to be washed with water at the same time, making the hassle of replacing attachments unbearable.

(c) Purpose of the invention The present invention was made in view of the problems of the conventional technology as described above, and it is possible to perform both finishing shave and shaving with a single machine, and it also has a finish shaving blade and a shaving blade. It is an object of the present invention to provide an electric shaver with serrated blades that can be cleaned at once and efficiently.

(d) Structure of the invention A metal outer cutter frame with a dome-shaped outer cutter attached to the upper part of a synthetic resin cylindrical main body case and a cutter blade storage part in which a cutter blade is arranged so as to be able to appear and retract freely are arranged vertically. The sharpening blade storage section is divided into a shaving blade storage section and a shaving blade storage chamber, and the shaving blade storage section is formed on one side of the shaving blade storage section. An outer blade drainage port communicating with the slope-shaped guide path and a sharpening blade drainage port communicating with the sharpening blade storage chamber are formed to remove shavings from the shaving waste reservoir and the sharpening blade storage. can be efficiently discharged.

(e) Example 1 is a cylindrical main body case made of synthetic resin,
A motor storage part 2 is formed in the upper part of the motor storage part 2 to store a motor 3, and a battery (not shown) is removably stored in line with the motor 3 through an opening (not shown) provided in the bottom part. is the main body case 1
It is closed with a bottom cover 4 that is screwed and fixed to the bottom.

A ring-shaped switch actuator 5 is provided rotatably around the outer periphery of the motor housing 2.
It has a knob 6 on its outer circumferential surface, and a sloped projection 7 and a joint projection 8 are provided on its inner circumferential surface, facing each other. A circular hole 9 is formed on one side flat surface of the motor storage section 2, into which a waterproof elastic packing 10 is fitted, and the switch operating body 5 is fitted onto the outer periphery of the motor storage section 2 with its sloped projection 7 adjacent to a hard ball 11 pressed into approximately the center of the outer surface of the elastic packing 10.

Reference numeral 12 denotes a lead plate attached to a fixed base 13 made of synthetic resin, which is engaged and fixed to the inner circumferential wall of the main body case 2 via the fixed base 13 and arranged in the vertical direction, and is formed on the upper part thereof. movable contact piece 14
is in constant contact with the inner surface of the elastic packing 10. Further, reference numeral 15 denotes a fixed contact piece, which is fixed to the side surface of the motor 3 opposite to the movable contact piece 14, and the lower end of the fixed contact piece 15 is soldered to a terminal (not shown) on the bottom of the motor 3. Fixed. The lower end of the lead plate 12 is connected to a cathode contact plate (not shown) that is in constant contact with the cathode of the battery through a cathode connection ring (not shown) fitted to the inner peripheral surface of the bottom of the main body case 1. It is connected.

Reference numeral 16 denotes a motor cover that covers the motor housing 2 and prevents the switch actuating body 5 from coming off upward;
It is fixed with screws via 7 and 17. Reference numeral 18 denotes a sharpening blade storage section, in which a sharpening blade 19 is provided so as to be freely protrusive via an operating lever 20 on the side. Drain ports 21 and 22 are formed which are opened and closed by movement. A metal outer cutter frame 23 has a net-shaped outer cutter 24 attached to its upper part, and is screwed into the upper part of the edge cutting blade storage section 19. A cam 26 is attached to the drive shaft 25 of the motor 3.
A cap 27 having a lower part is fitted,
Further, a waterproof rubber 28 is attached to the upper surface of the motor 3.

FIG. 3 is a front view of the edge blade storage section 18. The razor blade storage section 18 is divided into an upper razor shavings storage section 29 and a shaving blade storage chamber 30 (see Fig. 4b), and is gradually inclined downward toward the shaving shavings storage section 29. slope-shaped guideway 31 (Fig. 4a)
) is formed, and the outer end of the guide path 31 communicates with the outer blade drainage port 21. Further, the sharpening blade drain port 22 is located below, separated from the outer cutter drain port 21, and communicates with the sharpening blade storage chamber 30. Reference numeral 32 designates a through hole for inserting a cap 27 fitted to the drive shaft 25 of the motor 3, and an inner cutter (not shown) fitted to the cap 27 is inserted above the shaving dust reservoir 29. To position.

When washing with water, the operation lever 20 is moved to open both the drain ports 21 and 22, the outer cutter 24 and the edge cutting blade 19 are thrown into the water, and the switch operating body 5 is rotated to make the movable When the contact piece 14 is brought into contact with the fixed contact piece 15 and the motor 3 is driven to rotate the inner cutter, a water flow is generated in the shaving debris reservoir 29 due to the rotation of the inner cutter, and the water flow is The fallen shavings are smoothly discharged from the outer cutter discharge port 21 through the inclined guide path 31, and the shavings in the sharpening blade storage chamber 30 are also carried by the flow to the sharpening blade. It is discharged outward from the discharge port 22.

(f) Effects of the invention As explained above, the present invention allows the outer cutter frame, in which the outer cutter is attached to the upper part of the cylindrical main body case, and the cutter blade storage part, in which the cutter blade is disposed so as to be freely retractable, to be vertically connected. The sharpening blade storage section is divided into a shaving blade storage section and a shaving blade storage chamber, and the shaving blade storage section is formed on one side of the shaving blade storage section. Since the outer cutter drain port communicates with the slope-shaped guide path and the cutter blade drain port communicates with the cutter blade storage chamber, there is no need to replace the outer cutter and the cutter blade. It is very convenient as it eliminates the need for
Shaving debris can be discharged separately from the outer blade part and the razor blade part, and even if the drain port is small, it can be expected to be discharged without becoming clogged.
