Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reciprocating electric oven, and relates to the size of the outer shell of the main body case.

Prior art A conventional reciprocating electric shaver has an outer shell made of a rectangular main body case made of synthetic resin, and a vibrating table with a vertically installed vibrating rod for reciprocating the inner blade in the horizontal direction. The motor is installed so that the axial direction of the drive shaft is directly fired with respect to the driving direction (=, one side or both sides of the motor (two sides) Rechargeable batteries or dry batteries are installed.

However, with this arrangement, the IT main body case is formed to be elongated, giving the user a false impression that the reciprocating electric shaver is large, heavy, and difficult to handle.

Therefore, there is a growing demand for an excellent reciprocating electric shaver that is portable and functional (like a makeup compact that two people carry together).

Purpose of the Invention The present invention has been made in view of the problems of the prior art as described above (2).The main body case is approximately round in plan and is shaped to fit comfortably into the palm of an adult's palm, thus eliminating wasted space. It is an object of the present invention to provide a reciprocating electric shaver in which various constituent members can be arranged without leaving any loose parts or wobbling.

Structure of the Invention A vibrating table having a vertically installed vibrating rod for reciprocating the inner cutter body is provided inside a synthetic resin main body case having a substantially round shape in plan view, and the axis of the drive shaft is set relative to the reciprocating direction of the vibrating table. C'-1 A reciprocating electric shaver with a plurality of batteries arranged between the vibrating table and the motor. This is a reciprocating electric shaver in which the outer shell of the main body case is limited to a diameter of 85 seconds or less.

Example: An example of a reciprocating electric shaver incorporating drive members such as two reciprocating outer blades and reciprocating inner blades (see the drawing (details along C

Further, the lower surface of the vibration table Q4 is brought into contact with a metal movement support plate (42) C attached to the lip (10a) of the main body case (1), and the motor is driven. The vibration table (24) is reciprocated in the horizontal direction (bi-stable) with the help of the sliding auxiliary plate (421). The vibration table Q40 is provided with a circular hole (41), which is a hole for inserting a jig such as a screwdriver when fixing the motor holding plate (11) to the motor (2) on the upper surface C2.

Main body case (1) interior side C; installed motor M

6) constitutes the main switch (BY).

The switch piece 1161 is operated by protruding through the opening 0 mark provided on the other side of the main body case (1), and is always pushed outward by the elasticity C2 of the switch piece ae. The switch actuator weight is elastically biased, and the switch actuator rod can be pushed inward from the outer blade of the main body case (11), and the switch actuator body can be pushed inward from the outer blade of the main body case (11). The sliding position (: Therefore, it protrudes from the opening 08 or is recessed inward. That is, the inward direction of the fan-shaped body (4) (: indicates the two recesses A that hold the switch actuating body cover in the production position. A protrusion (40) is formed between (4a) and B (41)) for inwardly recessing the writing switch actuating member.Therefore, the force of the fan-shaped body (4) is similar to the shaving portion!! 31
The head of the switch actuating body tll protrudes from the aperture a8 while covering the switch operating body tll. When the fan-shaped body (41) is slid to expose the shaving part!! 31, the head of the switch actuating body O9 enters the recess A (4a), and is further slid.

The outer blade frame (7) can be removed for the first time from the top of the main case (see 7!12).

Wi] While the fan-shaped body (4) covers the barbed part, the cutting and raising sui7te actuating body I11 covers the body case (1).
The main switch (SW) is turned ON/L even with a slight pressure (12), and the inner blade body (Dan) is driven. The main body case (11) is provided with a locking member (5) that can be slid freely along the surface of the main body case (11). The actuating body (11 is C2 shaped so that it does not dent inward) and the locking member (4) is designed to prevent the lock from working unnecessarily. The case il + the dowel mark on the inner surface constitute an articulation mechanism.

Effects of the Invention As described above, the present invention provides a vibrating table in which a vibrating rod is vertically installed inside a main body case having a substantially round planar shape, and causes the axial direction of the drive shaft to be fired directly with respect to the reciprocating direction of the vibrating table. In a reciprocating electric shaver, in which a motor is provided and several batteries are arranged in a compartment defined by the vibrating table and the motor, the outer shell of the shearing main body case has a diameter of 85 mm. Within the following circumference range (- By limiting the circumference, it is possible to construct a round electric shaver that is the same size as the palm of an adult's hand (2). In addition, the shaving part formed on the round main case can be oriented at any angle to the hand depending on the grip of the main case, and can be easily used in various places and deep places. (It has great practical effects, such as being able to shave twice.

In addition, in the circumference of 85 mm in diameter, it is parallel to the motor (= the minimum dimension set as a size that allows two batteries to be installed side by side.
