Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electric shaver equipped with a comb blade unit for edge shaving in addition to a razor blade unit.

[Conventional technology]

This type of electric razor has a structure in which a shaving case in which a comb blade unit for shaving is housed so as to be able to swing in and out is slidably attached to the main body case, so that the shaving case doubles as a switch operation knob. There is something like that. That is, the edge shaving case is slidably attached to the side surface of the main body case in three vertical positions: a lowermost non-use position, an intermediate position one step above it, and an upper use position. Then, when the edge shaving case is in the non-use position, the connection between the motor and the power source is cut off and the switch is turned off, and when the edge shaving case is in the intermediate position and the use position, the power source and the motor are connected and the switch is turned on. shall be. Further, as the edge shaving case moves from the intermediate position to the use position, the comb blade unit is swung to protrude from the edge shaving case, and when the edge shaving case is in the intermediate position and the non-use position, the comb blade unit is moved to the edge shaving case. It is assumed that it is stored inside. In other words, the edge shaving case is in the non-use position (switch off position).
When the razor blade unit is pushed up one step to the intermediate position, the inner blade of the razor blade unit is driven to enable its use, and when the edge shaving case is pushed up to the cutting position, the movable comb blade of the comb blade unit is driven. It is designed to enable its use.

[Problem to be solved by the invention]

The problem is that when the comb blade unit of the above-mentioned electric razor is protruded, the motor is always energized and the movable comb blades of the comb blade unit are driven. It is not possible to clean the hair that has adhered to the blade unit, and at most the hair can only be shaken off from the comb blade unit in an idle state, and the blade tip of the comb blade unit 7 becomes increasingly dirty. As a result, rusting was accelerated, and the sharpness was likely to deteriorate early.

The present invention provides an electric shaver as described above (in which the edge shaving case in which the comb blade unit is retractably stored doubles as a switch operation knob), by improving the mechanism for moving the comb blade unit in and out. , the purpose is to make the comb blade unit protrude when the motor is not driven so that it can be safely cleaned with a bristle brush, etc.
Furthermore, it is an object of the present invention to improve the ease of assembling the comb blade unit and the like to the edge shaving case.

Claims (1)

[Claims] (1) At the top of the main body case 1, an outer cutter 16 and an outer cutter 16 are provided.
It is equipped with an inner cutter 14 that is inscribed in the inner cutter 14 and driven by the motor 2 via an inner cutter drive mechanism, and on the side of the main body case 1, there is a lowermost non-use position, and an intermediate position one step higher than the inner cutter 14. A comb blade unit 61 consisting of a fixed comb blade 63 and a movable comb blade 64 is attached to the comb blade unit 61 in the comb blade case 4, which can be slid up and down over the upper usage position. It is pivotally connected to be able to swing in and out from an opening 60 formed in the case 4, and the relative vertical displacement between the main body case 1 and the wrinkle shaving case 4 is used to create a connection between the main body case 1 and the wrinkle shaving case 4. When the edge shaving case 4 is moved from the intermediate position to the use position, the comb blade unit 61 is protruded from the opening 60 and swung, and when the edge shaving case 4 is in the intermediate position and the non-use position, the comb blade unit 61 is opened. A comb blade unit retraction mechanism is provided to be stored in the comb blade unit 60, and a mechanism is provided between the motor 2 and the shaving case 4 to disconnect the motor 2 from the power source when the shaving case 4 is in a non-use position. A switch plate 44 for motor control is provided to connect the power source and the motor 2 when the edge shaving case 4 is in the intermediate position and the use position, and a switch plate 44 for controlling the motor is provided between the inner blade drive mechanism and the comb blade unit 61. The engagement between the movable comb blades 64 of the comb blade unit 61 and the inner blade drive mechanism is released when the case 4 is in the non-use position and the intermediate position, and the comb is in the protruding position only when the case 4 is in the use position. In an electric shaver that is provided with a comb blade drive mechanism that engages and interlocks the movable comb blades 64 of the blade unit 61 and the inner blade drive mechanism, the comb blade unit ejection/retraction mechanism is configured to move the comb blades inside the edge shaving case 4. It is provided with an urging spring 82 that swings and urges the blade unit 61 to the retracted position, and when the edge shaving case 4 is in the non-use position or the intermediate position, the comb blade unit 61 is in a free state, and the edge shaving case 4 is in the intermediate position. When moving the comb blade unit 61 from the biasing spring 82 to the use position,
The edge shaving case 4 has a comb blade unit drive chamber 6 closed by a cover plate 68 above the back side of the edge shaving case 4.
7 is formed in communication with the opening 60, and the comb blade unit 61, the comb blade drive mechanism, the comb blade unit egress/retraction mechanism, and the biasing spring 82 are housed in the drive chamber 67, and the edge shaving case The lower part 87 of the comb blade unit drive chamber 67 on the back side of the main body case 1 is formed into a flat plate shape.
