Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric shaver in which a dust suction device for sucking shavings is integrally connected to automatically clean shavings and shavings.

[0002]

2. Description of the Related Art Conventionally, an electric shaver that fixes an outer blade (mesh blade) and operates the inner blade at a high speed to cut a beard is usually a few pieces because the cut whiskers are left inside the outer blade. Since the outer blade is removed and cleaned every time, the beard waste adheres to the inner blade and its surroundings and it is troublesome to clean. Also, if the number of times of cleaning is simplified to several times or more, whiskers gradually accumulate around the inner blade, and due to the vibration of the inner blade that moves at high speed, whiskers are scattered from the blade hole of the outer blade to the outside during use. There is also a problem, and in order to remove this, it took time and effort to remove the outer blade attached to the main body and clean it with a special brush, etc., and there were various troublesome problems with the treatment of beard scraps. .

[0003]

The main reason for this is the structure in which the outer blade is curved to cover the inner blade, and the beard scraps cut by the inner blade are left inside. However, whiskers cut by the inner blade that operates at high speed are finely cut dust-like particles, so it is easy to mix this with gas and suck it in. The beard scraps can be easily cleaned by sucking the beard scraps together with the outside air, filtering them with a filter, and collectively disposing them with a dust bag or the like. According to the present invention, a suction port and a duct portion extending from the suction port are provided inside an outer blade of an electric razor to form a gas flow path, and a dust suction device (or a small vacuum cleaner) or the like is attached to the suction port. Suction dust, operate the electric razor and dust suction device arbitrarily by switching the power switch, and immediately remove the beard scraps that have been cut off and filter them with a filter to automatically clean the beard scraps, which was previously troublesome. The purpose is to provide an electric razor that can be done.

[0005]

[Operation] The electric razor configured as described above removes the whiskers cut by the inner blade 2 from the blade hole 4 of the outer blade 1.
Shavings can be easily cleaned by sucking the outside air (arrow) more sucked into the dust suction device 30 from the suction port 3 through the duct portion 5 and filtering the suction dust using the cassette filter 50. This action is based on a method of rotating the turbofan 21 of the dust suction device 30 at a high speed to generate a suction force, sucking whiskers and filtering the dust with a filter for cleaning. Therefore, if the dust suction device 30 is operated while shaving, it is possible to clean the shavings at the same time as the shaving, but immediately after the shaving is finished, the dust suction device 30 is operated to clean the shavings. For example, noise and vibration are small, and if the inner blade 2 is intermittently operated during this period to suck off the whiskers adhering thereto, it works more effectively. Moreover, if an external device having a strong suction force is used as the dust suction device and the suction hose or the like is used and the devices are connected at a distance from each other, a quieter and stronger suction action is achieved.
