Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary electric razor, and relates to the treatment of beard debris.

Conventionally, rotary electric razors aimed at making it easier to dispose of beard debris include:
A sweeper is attached to the motor output shaft within the hair receptacle formed between the inner blade and the motor, and the sweeper is rotated together with the inner blade by the motor to store hair debris in a pocket adjacent to the hair receptacle. What has been done is known. However, in such rotary electric razors, the sweeper is connected to the motor output shaft, and rotates together with the inner blade at a high speed of, for example, around 5000 r.Pm, which agitates the beard debris stored in the beard holder. However, there was a drawback that the beard debris would scatter from the outer cutter to the outside, increasing the amount of beard debris scattered during use.

The present invention was made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a rotary electric razor that collects beard debris in a pocket and facilitates disposal of beard debris while suppressing an increase in the amount of flying debris. shall be.

The present invention will be explained below based on the embodiments shown in FIGS. 1 and 2. 1 is an outer cutter made of a thin metal plate. Reference numeral 2 denotes an inner cutter that rotates in sliding contact with the inner surface of the outer cutter 1, and is provided with an inner cutter blade 2a. 3
is a motor which rotates an inner cutter 2 attached to a motor output shaft 3a and causes the outer cutter 1 to shave the beard.
Reference numeral 4 denotes a hair receiving part which is disposed between the inner cutter 2 and the motor 3 and where hair debris falls first, and the motor output shaft 3a passes through the center. Reference numeral 5 designates a pocket carved into the body 6 adjacent to the beard receiving part 4 for storing beard debris that has fallen into the beard receiving part, and has a beard receiving opening 5a which is an opening to the beard receiving part and an opening to the outside. It has a certain beard discharge port 5b. Reference numeral 7 denotes a shutter installed in the beard discharge port 5b, which closes the beard discharge port 5b to store the beard waste in the pocket 5, and opens the beard discharge port 5b to discharge the beard waste to the outside. 8 is a sweeper for moving beard debris to the beard receiving port 5a, and has three arms 8a extending radially around the motor output shaft 3a so as to be in almost sliding contact with the inner surface of the beard receiver 4; It is loosely fitted into the body and can be rotated. Note that the number of arms 8a is not limited to three, but may be one or more. Further, the sweeper does not need to rotate integrally with the motor output shaft, and it goes without saying that other parts may be interposed between the sweeper and the motor output shaft.

Now, when shaving, the inner cutter 2 attached to the motor output shaft 3a rotates and the outer cutter 1 shaves the beard.
Due to the viscous motive force caused by the rotation of the inner cutter blade 2a or the blowing effect of the inner cutter blade 2a, an air vortex is generated in the lower hair receiving portion of the inner cutter 2 in the direction of rotation of the inner cutter shown as arrow B in FIG. Then, the sweeper 8 loosely fitted to the motor output shaft 3a rotates at a low speed mainly due to the viscous force of the air caused by this vortex flow. Therefore, the beard debris accumulated in the beard receiving part 4 is removed by the sweeper 8.
The arm 8a moves the beard to the beard accommodating opening 5a and accommodates it in the pocket 5 while suppressing an increase in the amount of scattering due to stirring. Then, the beard debris stored in the pocket 5 is discharged from the beard discharge port by opening the shutter 7.

As described above, according to the present invention, since the sweeper rotates at a low speed, the beard debris can be stored in the pocket while suppressing an increase in the amount of beard debris scattered during use due to agitation, making it easier to dispose of the beard debris. can.
