Abstract

PURPOSE:To obtain the vibration condition corresponding to thickness and taste of a moustache, and also, to easily clean moustache refuse by making a vibration frequency by a vibration generating device variable, and also, providing an opening part for deading flowing water to a razor edge side on a fitting base of the razor edge. CONSTITUTION:By varying a resistance value of a variable resistor V connected in series to a motor 50 by operating a control 37, the number of revolution of the motor 50, and a vibration frequency of vibration by an eccentric weight 51 installed in its output shaft are varied. In the case the vibration frequency is varied, the amplitude is also varied, therefore, the vibration condition of the razor edge 4 can be set to that which corresponds to thickness and choice of a moustache. Also, since an opening part 12 for allowing the installation surface of the razor edge 4 and other surface in an edge fitting base 11 to communicate with each other is provided, flowing water is allowed to flow to the installation surface side of the razor edge 4 from one end side of the opening part 12, and moustache refuse clogged in the razor edge 4 can be washed and allowed to flow easily by the flowing water.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a vibrating razor that exhibits a beard cutting action by vibrating a razor blade.

[Conventional technology]

The most common means of shaving is a so-called safety razor; if you have a thick beard, you will have to use a lot of force when pressing it against the skin, and for this reason you will have to use a safety razor for a long time. There is a risk of cutting your skin. Electric shavers are generally equipped with an outer cutter and an inner cutter that slides against the inner surface of the outer cutter.
There are also vibrating razors, which vibrate the head to which razor blades are attached, similar to those used in safety razors. This type of razor disclosed in Japanese Patent Application Laid-Open No. 63-220898 has a razor blade attached to one end of a cylindrical main body housing, and an eccentric weight attached to the output shaft of a motor to generate vibration. The device is built into the main housing.

[Problem to be solved by the invention]

However, in the device disclosed in the above publication, since the frequency of the vibration generated by the vibration generator is always constant,
Some users were unable to select driving conditions according to the thickness of their beard or their preferences, and were not satisfied with the sharpness, smoothness, skin contact, speed, etc. In addition, when shaving, razor blades accumulate and become clogged, and the method described in item 1 generates vibrations while the razor blade is submerged in water. Although you can shake the beard shavings off the razor blade, it's not enough and you have to patiently wash it off with running water. The present invention has been made in view of these points, and its purpose is to provide a vibrating type that not only can obtain vibration conditions according to the thickness of the beard and preferences, but also allows easy cleaning of beard debris. There is a razor on offer.

[Means to solve the problem]

Therefore, the present invention provides a vibrating razor that has a built-in vibration generator to apply vibrations to the razor blade. It is characterized by an opening that leads to the side. [Function] According to the present invention, since the frequency of the vibration generated by the vibration generator is variable, the vibration conditions of the razor blade can be set to the desired state, and the beard shavings stuck in the razor blade can be removed. By setting the above-mentioned vibration condition to a resonant state, it is possible not only to easily shake it off, but also to easily wash it away with running water due to the presence of the opening. [Embodiment] The present invention will be described in detail below based on the illustrated embodiment.This vibrating razor has a razor blade 4 that can be detachably attached.
the head section 1 that can be clipped, the clip section 3 that is held during use, the vibration damping member 2 that is between the head section 1 and the clip section 3 and connects them, and the inside of the head section 1. The vibration generator 5 is configured to include a vibration generator 5 arranged at the The head part 1 has a mounting base 11 on the upper end side on which the razor blade 4 is detachably mounted.
The eccentric weight 51 is attached to the output shaft of 0. The grip part 3 includes a cylindrical housing 31 and a bottomed cylindrical battery cover 3 connected to the lower end of the housing 31.
A switch handle 33 is attached to the front surface of the housing 31, and a knob 37 is disposed at the center of a cover 35 attached to the rear side of the housing 31. A terminal base 34 is disposed inside the housing 31, and the switch handle 33 is attached to this terminal base 34.
A contact portion S is driven by a switch lever 36 that rotates as the slider is operated, and a variable resistor V whose resistance value is changed by the knob 37 is provided. The vibration damping member 2 connecting the head part 1 and the grip part 3 is a hollow pipe-shaped member made of rubber, elastomer, etc. The terminal base 34 in the grip part 3 and the head part 1 are provided with a mounting part to which the upper end is fitted and connected.
A lead wire is connected to the motor 5 and passed through the interior, and a small diameter portion 21 is exposed to the outside between the two mounting portions. Now, by operating the switch handle 33, the motor 50
When energized, the motor 50 rotates the eccentric weight 51 to generate vibrations. And the talent 3
By operating 7, the resistance value of the variable resistor ■ connected in series with the motor 50 is changed.
0 rotation speed, that is, the frequency of vibration caused by the eccentric weight 51 attached to the output shaft of the motor 50, can be changed, and when the frequency is changed, the amplitude also changes. , the vibration conditions of the razor blade 4 can be adjusted according to the thickness of the beard and preference. Assuming that the amplitude is constant, as shown in FIG. 3(b), generally speaking, as the frequency increases, the satisfaction with sharpness, smoothness, etc. increases. Furthermore, when the frequency is changed and it matches the resonant frequency, the amplitude becomes considerably large as shown in FIG. 6(a). If the razor blade 4 is immersed in water in this state, the beard debris stuck on the razor blade 4 can be easily shaken off. Furthermore, as shown in FIG. 2(a), this vibrating razor is provided with an opening 12 that communicates the mounting surface of the razor blade 4 with other surfaces of the blade mount 11, so that running water can be easily removed. By allowing the water to flow from one end of the opening 12 to the mounting surface of the razor blade 4, it is possible to easily wash away beard debris clogging the razor blade 4 with running water.

【Effect of the invention】

As described above, in the present invention, since the frequency of the vibrations generated by the vibration generator is variable, the vibration conditions of the razor blade can be changed depending on the thickness of the beard and preference. By utilizing the resonance conditions, it is possible to easily shake off beard shavings stuck in the razor blade, and furthermore, by using the resonance condition, it is possible to easily shake off beard shavings that are stuck in the razor blade. Washing can also be easily performed due to the presence of the opening.
