본 발명은 일상생활에서 신체청정을 위해 사용되는 초음파 면도기에 관한 것이다.The present invention relates to an ultrasonic shaver used for body cleansing in everyday life.

종래의 경우, 신체청정용구에 해당하는 면도기의 형태는 케이스 내에 밧데리와 회전모터가 장착되고, 해당 회전모터의 회전축에는 회전칼날을 부설하여, 스위치 작동에 따라 회전칼날이 회전되면서 신체의 털을 깎는 형태의 면도기가 소개되어 있으나, 이의 사용에 있어서, 세밀하게 털을 깎으려는 사용자의 선택에 의해, 압박을 가하면서 피부에 대해 회전칼날이 더욱 근접되게 하는 경우가 허다하였다. 이럴 경우, 피부손상의 우려가 있었고, 특히, 가압력에 의해 고정칼날의 형태변경 및 회전칼날과의 마찰력이 상대적으로 증대되어 칼날의 마모는 물론 마찰부하에 의해 깨끗한 면도상태를 얻기에는 어려운 문제점이 있었다.In the conventional case, a shaver corresponding to a body cleaning device has a battery and a rotating motor mounted in a case, and a rotating blade is attached to a rotating shaft of the rotating motor to cut hair while the rotating blade is rotated according to a switch operation. Although shavers of the type have been introduced, their use has often led to the rotational blades being closer to the skin while applying pressure by the user's choice to finely shave. In this case, there was a risk of skin damage, and in particular, the change of the fixed blade shape and the frictional force with the rotary blade are relatively increased by the pressing force, which makes it difficult to obtain a clean shaving state due to the wear of the blade and the frictional load. .

이에 본 발명은 상술한 바와같은 종래의 제반문제점을 충분히 감안하여 안출된 것으로, 초음파의 발진으로 모터를 구동하고, 모터의 회전축에 연결된 칼날에 초음파 진동을 가하므로써, 더욱 세밀하고 매끄러운 면도상태를 유도하는 초음파 면도기를 제공함에 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above-described general problems, and induces a finer and smoother shaving state by driving the motor by oscillation of ultrasonic waves and applying ultrasonic vibration to the blade connected to the rotating shaft of the motor. The purpose is to provide an ultrasonic razor.

이하, 첨부된 도면을 참조하여 본 발명의 목적을 달성하기 위한 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the technical configuration for achieving the object of the present invention.

도면 제1도는 본고안의 분해사시도에 관한 것으로, 회전칼날(2)과 회전축(3)을 고정볼트(2a)를 매개로하여 회전축(3) 상부의 체결홈(3a)에 조합하고, 진동판(4a)과, 세라믹판(4b)으로 구성된 진동수단(4)을 회전축(3)과 모터축(5a)에 체결수단(6)을 매개로 회전축(3) 하부의 체결홈(3b)과 모터축의 체결홈(5B)을 결합함과, 초음파모터 (5)에 초음파를 발진시키도록된 초음파 구동부(T)를 접속 연결하여 구성된 것으로, 미설명부호 B는 밧데리, V는 진동자, L1∼L6는 코일, C1∼C5는 콘덴서, R1∼R3는 저항인 것이다.1 is an exploded perspective view of the present invention, by combining the rotary blade (2) and the rotary shaft (3) in the fastening groove (3a) of the upper rotary shaft (3a) via the fixing bolt (2a), the diaphragm (4a) And a fastening groove 3b in the lower part of the rotary shaft 3 and the motor shaft by means of the fastening means 6 on the rotary shaft 3 and the motor shaft 5a by the vibration means 4 composed of the ceramic plate 4b. Combining the groove (5B), and connected to the ultrasonic drive unit (T) for oscillating the ultrasonic wave to the ultrasonic motor (5), reference numeral B is a battery, V is a vibrator, L 1 ~ L 6 is The coils, C 1 to C 5 are capacitors, and R 1 to R 3 are resistors.

이와같이 구성된 본 발명의 일실시예를 들어 작용효과를 설명하면 다음과 같다.Referring to the effect of the embodiment of the present invention configured as described above are as follows.

도면 제2도에서 보는 바와같이, 동작스위치(7)를 작동케되면 밧데리(B)의 전원공급이 초음파 구동부(T)에 인가되고, 초음파 구동부(T)에서 초음파를 발진시켜 초음파모터(5)가 구동하게 된다. 여기에서, 초음파모터(5)의 구동은 다음과 같이 이루어진다. 도면 제3도에서 보는 바와같이, 밧데리(B)의 전원이 인가되면 발진부(A)에 의해 주파수가 발진되고, 드라이브부(C)에 전달된 신호(초음파)에 의해 초음파모터(5)가 구동되는데, 여기에서, 주파수 자동추미 방식을 선택하여 부하의 변동에 따라 귀환부(B)에 의해 주파수가 자동추미되고, 이렇게 함으로써 초음파모터(5)는 구동하게 된다.As shown in FIG. 2, when the operation switch 7 is operated, the power supply of the battery B is applied to the ultrasonic driver T, and the ultrasonic driver T oscillates ultrasonic waves so that the ultrasonic motor 5 is operated. Will be driven. Here, the driving of the ultrasonic motor 5 is performed as follows. As shown in FIG. 3, when the power of the battery B is applied, the frequency is oscillated by the oscillation unit A, and the ultrasonic motor 5 is driven by the signal (ultrasound) transmitted to the drive unit C. Here, by selecting the frequency automatic tracking method, the frequency is automatically tracked by the feedback unit B in accordance with the change of the load, thereby driving the ultrasonic motor 5.

그와동시에, 초음파모터축(5a)에 체결수단(6)을 매개로 연결된 진동수단(4)및 회전축(3)과 고정볼트(2a)에 의해 회전축(3)에 연결된 회전칼날(2)이 회전하게 된다. 이때, 초음파 구동부(T)의 발진은, 편심되어 조합한 진동수단(4)에 진동신호를 인가하므로써, 회전칼날(2)의 회전과 아울러 미세한 진동으로(즉, 좌, 우 반복적인 이동이 떨림)구동되므로, 피부의 털을 깊숙히 깎아내는 역할을 하게 된다. 한편, 도면 제3도는 본 발명의 초음파모터 구동의 회로계통도에 관한 것으로, 이를 간략하게 설명하면 다음과 같다.At the same time, the vibrating means 4 connected to the ultrasonic motor shaft 5a via the fastening means 6 and the rotary blade 2 connected to the rotating shaft 3 by the rotating shaft 3 and the fixing bolt 2a are Will rotate. At this time, the oscillation of the ultrasonic drive unit T, by applying a vibration signal to the vibrating means (4) combined eccentrically, the rotation of the rotary blade (2) as well as fine vibration (that is, the left and right repeated movement shakes As it is driven, it acts to cut deep into the hair of the skin. On the other hand, Figure 3 relates to the circuit diagram of the ultrasonic motor drive of the present invention, briefly described as follows.

초음파 진동을 주기위한 초음파 구동부(T) 즉, 발진회로는 전원부, 발진부(A), 귀환부(D), 드라이브부(C)로 구성되어 있으며, 발진부(A)는 L, C발진회로 구성된다. 그 동작은 도면 제4도에서 보는 바와같이 트랜지스터(Q1, Q2)의 콜렉터 전압을 변압기(L4, L5)를 통해, 이상반전시켜 트랜지스터 베이스에 정궤환시킴으로써 발진되는 구조를 갖는다. 발진주파수는 L2, C1과 L3, C2로 결정되며 L4, C5는 귀환을 위한 코일이다. L2에 흐르는 전류가 램프형으로 증가하기 시작하여 시간이 흐름에 따라, 전류증가율을 감소하며 전류의 포화점에 가까와지면 트랜지스터 Q1의 컬렉터 전위 Vc(Q1)가 상승하고, 상승한 전위는 콘덴서 C1을 충전시키고, 트랜지스터 Q2의 베이스 전류가 증가하여 Q2는 온(ON)상태가 된다.The ultrasonic drive unit T for oscillating the ultrasonic wave, that is, the oscillation circuit is composed of a power supply unit, an oscillation unit A, a feedback unit D, and a drive unit C, and the oscillation unit A is composed of L and C oscillation circuits. . The operation has a structure that oscillates by positively inverting the collector voltages of the transistors Q 1 and Q 2 through the transformers L 4 and L 5 as shown in FIG. The oscillation frequency is determined by L 2 , C 1 and L 3 , C 2 , and L 4 and C 5 are coils for feedback. As the current flowing in L 2 starts to increase in a ramp type, and as time passes, the rate of current increase decreases and approaches the saturation point of the current. As a result, the collector potential Vc (Q 1 ) of the transistor Q 1 rises, and the rise of the potential The C 1 is charged, and the base current of the transistor Q 2 increases so that Q 2 is turned on.

여기서 반대로 동작하면 트랜지스터 Q1이 온되고 이렇게 반복 동작하여 발진이 일어나게 된다. 발진된 출력은 변압기(T1)를 통해 증폭되어, 초음파모터(5) 측에 진동을 가함으로써 전기적신호를 기계적인 진동에너지로 변환하게 된다. 이러한 진동에너지를 진동수단(4)에 전달하여 결국에는 회전칼날(2)이 진동되게 하는 것이다.Here, if the operation is reversed, the transistor Q 1 is turned on and the oscillation occurs by repeating the above operation. The oscillated output is amplified by the transformer T 1 to convert the electrical signal into mechanical vibration energy by applying vibration to the ultrasonic motor 5 side. This vibration energy is transmitted to the vibration means (4) to eventually cause the rotary blade (2) to vibrate.

이상에서 본 바와같이 회전칼날(2)에 미세한 진동으로 보다 빠른시간에 깨끗한 면도를 할 수가 있어 종래의 불편함을 배제토록 한 것이다.As seen above, it is possible to clean the shave in a faster time with a fine vibration to the rotary blade (2) to eliminate the inconvenience of the conventional.
