Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electric razor capable of discharging hair debris from a part of the sweep outlet of the circumference of a hair tray when cleaning the dust, for opening and closing the sweep opening. This is an improvement to the position setting of the operation knob of.

[Conventional technology]

As an electric shaver of this kind, for example, as shown in FIG. 16, a slide type operation knob 99 for opening and closing a sweep outlet 46 opened at a part of the circumference of the hair tray 19 on the upper part of the main body case 1 is provided on the main body case 1. There is a device provided on the front surface below the bristle tray 19 side by side with the switch operation knob 98 (Japanese Patent Laid-Open No. 142842/1982).

In addition, as shown in FIG. 17, an operating knob 99 for opening and closing the sweep outlet 46 of the bristle tray 19 is provided in a projecting shape at a position corresponding to the outer periphery of the bristle tray 19 on the upper part of the main body case 1. (Japanese Utility Model Publication No. 59-108573).

[Problems to be solved by the device]

There is a possibility that the position of the operation knob 99 may be erroneously checked,
Especially, when the operation knob 99 is arranged close to the switch operation knob 98, there is a great tendency to confuse the position for confirmation. Such misrecognition of the position of the operation knob 99 may cause shaving while the sweep outlet 46 is open, and in such a case, lint is discharged from the sweep outlet 46,
There is a disadvantage in that the operation knob 99 is hurriedly returned to the closed position.

Further, as shown in FIG. 17, when the operation knob 99 is always protruding from the position corresponding to the outer periphery of the hair receiving tray 19, when the razor is carried in a bag or the like, the operation knob 99 is easily touched by other objects, It was confirmed that the sweep outlet 46 was opened unexpectedly and lint was generated.

The present invention solves the above problems of the conventional product all at once and makes it easy to confirm the switching position of the knob, especially the opening position by devising the position setting of the operating knob for opening and closing the outlet. The purpose is to prevent accidental opening of the outlet.

[Means for Solving the Problems]

In order to achieve the above object, in the electric shaver of the present invention, as shown in FIGS. 1 and 2, in order to make it easy to confirm the position of the operating knob 50 for opening and closing the outlet, the grip portion 5 of the main body case 1 is provided.

Shutter ring 47 is provided, and one of the shutter ring 47 and the bristle tray 19 is rotated relative to the other, so that the sweep outlet 48 is provided.
It is premised that the electric shaver is configured such that the hair debris in the hair tray 19 is discharged from the sweep outlets 46 and 48 in a state where the 46 match each other.

Then, the shutter ring 47 or the hair tray 1
An operation knob 50 for rotating 9 is extended from the shutter ring 47 or the bristle tray 19 in the radial direction.

In the non-cleaning state in which the sweep outlet 46 of the bristle tray 19 is closed by the shutter ring 47, the operation knob 50 is positioned in an overlapping manner on the one surface 5a of the grip portion 5 of the main body case 1, and the sweep outlet 46 is provided. -In a cleaning state in which 48 are matched with each other, they are slidably moved from above the one surface 5a to the outside of the one surface 5a and protrude.

Further, a bulging portion 94 surrounding the switch operating knob 50 is provided on the one surface 5a of the grip portion 5 of the main body case 1, and the operating knob 50 has a shutter ring 47 closing the sweep outlet 46 of the bristle tray 19. Operation knob 50 in the non-cleaning state
The operation knob 50 is wholly or partially overlapped on the one surface 5a and coincides with the position of the bulging portion 94, and the operating knob 50 is wholly or partly in the position of the bulging portion 94 in a cleaning state in which the sweep outlets 46 and 48 are coincident. It is designed so that it slides out in the direction away from and sticks out.

[Action]

In the non-cleaning state in which the outlet 46 of the hair tray 19 is closed,
That is, when not in use or when using a shave, the entire operation knob 50 is the one surface 5 of the grip portion 5 a of the main body case 1.
Since the operation knob 50 is positioned in an overlapping manner on the surface a, it is possible to reduce the contact of the operation knob 50 with other objects as much as possible and prevent the accidental opening of the sweep outlet 46.

Further, in the cleaning state in which the sweep outlet 46 of the bristle tray 19 is opened, the whole or part of the operation knob 50 protrudes from the one surface 5a or the bulging portion 94 and is designed in relation to the one surface 5a or the bulging portion 94. As a result, it is possible to avoid forgetting to close the operation knob 50 by prompting the operator to return the operation knob 50 to the original closed position after cleaning.
