인덕션방식에 의해 충전재를 가열하는 치과용 충전기Dental charger to heat filling materials by induction method

본 발명은 치과용 충전기에 관한 것으로서, 충전재를 인덕션방식에 의해 가열하도록 구조가 개선된 치과용 충전기에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental charger, and more particularly, to a dental charger having an improved structure to heat a filler by an induction method.

치과에서는 충치를 치료하는 방법으로 치아의 썩은 부위를 천공기구를 이용하여 제거하고, 치수가 손상된 경우는 손상되거나 오염된 치수를 제거한 후 치료 부위인 근관에 충전재(근관충전용 시멘트 또는 씰러)를 채워 넣어 밀폐시킨 상태에서 보철하는 방법을 이용하고 있다. In the dental clinic, tooth decay is removed using a drilling tool. If the pulp is damaged, the damaged or contaminated pulp is removed, and a filling material (cement or sealer for root canal filling) is filled in the root canal. The method of prosthetic use is carried out in a sealed state.

이렇게 근관을 충전할 때는 충전재가 근관에 침투하여 완전히 폐쇄할 수 있도록 보조하는 임시 충전물로서 구타페프카 콘을 이용하게 된다. 구타페프카 콘을 근관벽에 밀착시키기 위한 충전기로 공개실용 2008-0003483호와 공개특허 2008-0080470호에 개시된 치과용 충전기(옵츄레이터)가 사용된다. When filling the root canal, the gutta-pepca cone is used as a temporary filler to assist the filling material to penetrate and completely close the root canal. A dental charger (operator) disclosed in Korean Unexamined Patent Application Publication Nos. 2008-0003483 and JP-A-2008-0080470 is used as a charger for bringing the gutta-peka cone into close contact with the root canal wall.

개시된 바와 같은 종래 치과용 충전기는 충전재를 니들을 이용해 치아로 공급할 때 충전재를 가열하기 위해 열선히터가 사용된다. 즉, 열선히터가 카트리지 외부에 권선되어 카트리지를 히팅함으로써 내부의 충전재를 가열시킨다. Conventional dental chargers, as disclosed, use a heated heater to heat the filler when it is supplied to the tooth with a needle. That is, a hot wire heater is wound outside the cartridge to heat the filler therein by heating the cartridge.

그러나, 이러한 종래 치과용 충전기는 열선히터에서 발생되는 열량 중 외부로 손실되는 열량이 많아 상대적으로 열효율이 떨어지는 단점이 있었다. 또한, 열선히터에 의해 카트리지만 가열되는 것이 아니고 외측에 위치한 외부케이싱도 가열되므로 충전재의 충전시에 환자의 구순에 접촉되어 환자가 화상을 입는 문제가 발생될 수도 있다. However, such a conventional dental charger has a disadvantage in that the thermal efficiency is relatively low in the amount of heat lost to the outside of the heat generated from the heating heater. In addition, not only the cartridge is heated by the hot wire heater, but the outer casing located outside is also heated, so that the patient may be burned by contact with the patient's mouth when the filler is filled.

또한, 종래 치과용 충전기는 열선히터의 열이 전도방식에 의해 카트리지를 가열하기 때문에 목표온도와 열선히터의 온도차가 크게 된다. 따라서, 온도센서의 부착위치에 따라 목표온도와 열선히터 사이의 온도편차가 상이해 실제 카트리지의 목표온도를 제어하기 어려운 문제가 있다. In addition, in the conventional dental charger, since the heat of the heater heater heats the cartridge by the conduction method, the temperature difference between the target temperature and the heater heater becomes large. Therefore, there is a problem that it is difficult to control the target temperature of the actual cartridge because the temperature deviation between the target temperature and the heater heater is different depending on the attachment position of the temperature sensor.

본 발명의 목적은 상술한 문제를 해결하기 위한 것으로, 열손실을 줄여 효율적으로 충전재를 가열할 수 있는 치과용 충전재를 제공하는 것이다. An object of the present invention is to solve the above problems, to provide a dental filler that can efficiently heat the filler by reducing the heat loss.

본 발명의 다른 목적은 충전재가 수용되는 카트리지만 가열하여 환자를 안전하게 시료할 수 있는 치과용 충전재를 제공하는 것이다. It is another object of the present invention to provide a dental filler that can safely sample a patient by heating only the cartridge in which the filler is housed.

또한, 카트리지의 크기와 상관없이 적정열량이 공급되어 일정한 온도로 발열할 수 있는 치과용 충전재를 제공하는 것이다.In addition, an appropriate amount of heat is supplied irrespective of the size of the cartridge to provide a dental filler that can generate heat at a constant temperature.

본 발명의 상기 목적과 여러 가지 장점은 이 기술분야에 숙련된 사람들에 의해 본 발명의 바람직한 실시예로부터 더욱 명확하게 될 것이다.The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention by those skilled in the art.

본 발명의 목적은 치과용 충전기에 의해 달성될 수 있다. 본 발명의 치과용 충전기는, 내부에 배터리가 수용되는 손잡이하우징과, 상기 손잡이하우징의 상부에 마련되는 상부하우징을 갖는 충전기본체와; 상기 상부하우징의 선단에 결합되며 내부에 충전재가 수용되고, 상기 충전재를 외부로 배출시키는 니들부재가 결합되며, 금속소재로 형성된 충전재카트리지와; 상기 충전재카트리지의 외부를 감싸게 상기 충전기본체 내부에 구비되어 상기 충전재카트리지를 유도가열방식으로 가열하는 가열유닛과; 상기 충전재카트리지의 후단부를 가압하여 상기 충전재가 상기 니들부재를 통해 외부로 배출되도록 하는 피스톤유닛과; 상기 피스톤유닛을 구동시켜 상기 충전재를 공급하도록 하는 구동부를 포함하며, 상기 가열유닛은, 상기 충전재카트리지의 외측에 권취되며 고주파 전류를 공급받는 인덕션코일을 포함하며, 상기 인덕션코일에 의해 발생된 와류전류가 상기 충전재카트리지를 유도가열하여 상기 충전재를 가열하는 것을 특징으로 한다. The object of the invention can be achieved by a dental charger. Dental charger of the present invention, the charger body having a handle housing, the battery housing therein, and an upper housing provided on the handle housing; A filler cartridge coupled to the front end of the upper housing and accommodating a filler therein and having a needle member for discharging the filler to the outside and formed of a metal material; A heating unit provided inside the charger body to surround the outside of the filler cartridge to heat the filler cartridge in an induction heating method; A piston unit pressurizing a rear end of the filler cartridge to discharge the filler to the outside through the needle member; And a driving unit for driving the piston unit to supply the filler, wherein the heating unit includes an induction coil wound outside the filler cartridge and supplied with a high frequency current, and the eddy current generated by the induction coil. Induction heating of the filler cartridge is characterized in that for heating the filler.

일 실시예에 따르면, 상기 충전재카트리지와 상기 인덕션코일 사이에는 절연체 또는 비자성 금속체가 구비된다.According to one embodiment, an insulator or a non-magnetic metal body is provided between the filler cartridge and the induction coil.

일 실시예에 따르면, 상기 충전재카트리지는 상기 충전기본체 내부에 착탈가능하게 결합될 수 있다. According to one embodiment, the filler cartridge may be detachably coupled inside the charger body.

일 실시예에 따르면, 상기 인덕션코일은 상기 배터리와 연결되어 전원을 공급받을 수 있다. According to an embodiment, the induction coil may be connected to the battery to receive power.

본 발명에 따른 치과용 충전기는 인덕션히팅 방식에 의해 충전재카트리지를 가열하게 되므로 외부 열손실이 적어 열효율이 증가될 수 있다. 또한, 충전재카트리지만 가열하게 되므로 다른 구성들로 열이 전달되지 않아 환자의 구순에 접촉되더라도 안전하게 사용할 수 있다. The dental charger according to the present invention is to heat the filler cartridge by the induction heating method, so the external heat loss is less, the thermal efficiency can be increased. In addition, only the filler cartridge is heated so that heat is not transferred to other components, so that it can be used safely even if the patient is in contact with the labia.

또한, 충전재카트리지만 가열되고 타 부분들은 히팅되지 않으므로 온도센서에 의한 목표온도 제어가 용이하다. In addition, since only the filler cartridge is heated and the other parts are not heated, it is easy to control the target temperature by the temperature sensor.

또한, 외부 조건에 관계없이 일정하게 열이 발생되므로 충전재를 일정한 온도로 가열할 수 있다. In addition, since the heat is constantly generated regardless of external conditions, the filler can be heated to a constant temperature.

The handle housing 11 accommodates a battery 12 and a circuit board (not shown).

가열유닛(20)은 피스톤유닛(60)의 가압을 통해 니들부재(30)로 공급되는 충전재를 가열하여 연화시킨다. 가열유닛(20)은 인덕션방식에 의해 충전재를 가열한다. 도 4은 가열유닛(20)의 구성을 확대하여 도시한 확대단면도이고, 도 3은 가열유닛(20)의 구성을 도시한 투영사시도이고, 도 5는 가열유닛(20)의 인덕션히팅 방식을 도시한 예시도이다. The heating unit 20 heats and softens the filler supplied to the needle member 30 through the pressure of the piston unit 60. The heating unit 20 heats the filler by the induction method. 4 is an enlarged cross-sectional view showing an enlarged configuration of the heating unit 20, Figure 3 is a perspective perspective view showing the configuration of the heating unit 20, Figure 5 shows an induction heating method of the heating unit 20. This is an example.

가열유닛(20)은 도 3에 확대도시된 바와 같이 상부하우징(13)의 선단에 결합되는 외부케이싱(21)과, 충전재카트리지(50)의 외측을 감싸는 인덕션코일(24)과, 인덕션코일(24)과 충전재카트리지(50) 사이에 배치되는 절연파이프(25)와, 외부케이싱(21) 내측에 형성되는 보호케이싱(23)을 포함한다. As shown in FIG. 3, the heating unit 20 includes an outer casing 21 coupled to the front end of the upper housing 13, an induction coil 24 surrounding the outside of the filler cartridge 50, and an induction coil ( Insulating pipe 25 disposed between the 24 and the filler cartridge 50, and a protective casing 23 formed inside the outer casing (21).

외부케이싱(21)은 상부하우징(13)의 선단에 착탈가능하게 결합된다. 외부케이싱(21)을 상부하우징(13)으로부터 분리한 후 충전재카트리지(50)를 착탈할 수 있다. 보호케이싱(23)은 외부케이싱(21)의 내측에 구비되어 인덕션코일(24)에서 발생된 열이 외부로 전달되는 것을 차단한다. 보호케이싱(23)은 시료중에 환자의 구순과 접촉될 수 있으므로 실리콘과 같은 절연재질로 구비된다.The outer casing 21 is detachably coupled to the tip of the upper housing 13. After removing the outer casing 21 from the upper housing 13, the filler cartridge 50 can be detached. The protective casing 23 is provided inside the outer casing 21 to block heat generated from the induction coil 24 from being transferred to the outside. The protective casing 23 is made of an insulating material such as silicon because the protective casing 23 may be in contact with the patient's mouth in the sample.

또한, 보호케이싱(23)과 인덕션코일(24) 사이에는 절연파이프(25)를 더 설치하여 인덕션코일(24)의 열이 외부로 전달되는 것을 이중으로 차단한다. 절연파이프(25)는 테프론, 유리, 나무, 피크 등으로 구비될 수 있다. 또한, 절연파이프(25)는 자성이 없는 금속재료로 구비될 수도 있다. In addition, an insulating pipe 25 is further provided between the protective casing 23 and the induction coil 24 to double the heat transfer of the induction coil 24 to the outside. The insulation pipe 25 may be provided with Teflon, glass, wood, peak, or the like. In addition, the insulating pipe 25 may be made of a metal material having no magnetic property.

인덕션코일(24)은 가압스위치(73)의 작동에 의해 배터리(12)의 전원을 공급받는다. 인덕션코일(24)은 충전재카트리지(50)의 외주연에 복수회 권취되어 충전재카트리지(50)의 발열면적을 감싼다. 전원의 공급에 따라 도 5에 도시된 바와 같이 인덕션코일(24) 내부로 고주파 전류가 유입된 후 화살표로 표시한 바와 같이 순환하며 이동된다. 이러한 인덕션코일(24) 내부의 전류의 흐름은 충전재카트리지(50) 내부에 전류의 흐름과 반대방향의 자기장을 일으키다.Induction coil 24 is powered by the battery 12 by the operation of the pressure switch (73). The induction coil 24 is wound around the outer periphery of the filler cartridge 50 a plurality of times to cover the heat generating area of the filler cartridge 50. As shown in FIG. 5, a high frequency current flows into the induction coil 24 as shown in FIG. 5, and then circulates and moves as indicated by arrows. The flow of current in the induction coil 24 causes a magnetic field in the opposite direction to the flow of current in the filler cartridge 50.

자기장은 인덕션코일(24)의 주위에서 생성되고, 생성된 자기장의 세기는 충전재카트리지(50)의 표면에서 열로 변환된다. 이에 의해 충전재카트리지(50) 표면이 뜨거워지면서 내부에 수용된 충전재(S)도 가열되며 연화된다.  A magnetic field is generated around the induction coil 24, and the intensity of the generated magnetic field is converted into heat at the surface of the filler cartridge 50. As a result, the surface of the filler cartridge 50 becomes hot, and the filler S accommodated therein is also heated and softened.

이 때, 자기장에 의해 발생되는 열은 인덕션코일(24)의 굵기, 인덕션코일(24)의 권취횟수, 인덕션코일(24)로 공급되는 공급전력 주파수, 충전재카트리지(50)의 재질 등에 의해 영향을 받게 된다. 따라서, 인덕션코일(24)은 배터리(12)로부터 공급되는 일정한 전력에 대해 충전재(S)를 충분히 가열할 수 있는 열량을 제공하기 위해 상술한 영향인자들을 고려하여 형상과 굵기 및 권취회수를 결정하게 된다. At this time, the heat generated by the magnetic field is affected by the thickness of the induction coil 24, the number of windings of the induction coil 24, the power supply frequency supplied to the induction coil 24, the material of the filler cartridge 50, and the like. Will receive. Therefore, the induction coil 24 determines the shape, thickness, and number of windings in consideration of the above-described influence factors in order to provide the amount of heat capable of sufficiently heating the filling material S with respect to a constant power supplied from the battery 12. do.

이러한 인덕션코일(24)의 인덕션히팅 방식에 의해 충전재카트리지(50)를 가열하게 됨으로 인해 충전재카트리지(50)만 가열할 수 있게 된다. 즉, 종래 히팅코일에 의해 충전재카트리지(50)를 가열할 경우 충전재카트리지(50) 뿐만 아니라 외부로도 열이 전달되어 외부케이싱과 보호커버가 가열되어 환자의 구순에 손상을 주던 문제를 해결할 수 있다. Since the filler cartridge 50 is heated by the induction heating method of the induction coil 24, only the filler cartridge 50 can be heated. That is, when the filler cartridge 50 is heated by a conventional heating coil, heat is transferred not only to the filler cartridge 50 but also to the outside so that the outer casing and the protective cover are heated, thereby solving the problem of damaging the patient's mouth. .

또한, 일정한 전력공급에 의해 인덕션코일(24)에 의해 유도되는 자기장의 세기가 일정하므로 일정량의 열량이 발생하게 되므로 외부 조건과 상관없이 항상 충전재가 균일한 온도를 유지할 수 있게 된다. In addition, since the intensity of the magnetic field induced by the induction coil 24 by a constant power supply is constant, a certain amount of heat is generated, so that the filler can always maintain a uniform temperature regardless of external conditions.

또한, 인덕션코일(24) 자체는 거의 발열되지 않고 충전재카트리지(50)만 가열되므로 온도센서에 의한 제어가 용이해 사용자의 온도설정이 편리하다. In addition, since the induction coil 24 itself hardly generates heat, and only the filler cartridge 50 is heated, the induction coil 24 is easily controlled by a temperature sensor, and thus the user's temperature setting is convenient.

니들부재(30)는 충전재카트리지(50)의 선단에 일체로 결합된다. 니들부재(30)는 가열유닛(20)에 의해 가열된 충전재(S)를 환자의 구순으로 공급한다. The needle member 30 is integrally coupled to the tip of the filler cartridge 50. The needle member 30 supplies the filler S heated by the heating unit 20 in the patient's mouth.

충전재카트리지(50)는 가열유닛(20)의 내부에 수용된다. 충전재카트리지(50)는 내부에 충전재가 수용된 상태로 가열유닛(20)의 내부에 결합된다. 이 때, 충전재카트리지(50)의 후단부는 피스톤부재(63)에 접촉되게 배치되고, 작동손잡이(71)의 작동여부에 따라 피스톤부재(63)가 전진하면서 충전재카트리지(50)를 가압한다. The filler cartridge 50 is housed inside the heating unit 20. The filler cartridge 50 is coupled to the inside of the heating unit 20 in a state where the filler is accommodated therein. At this time, the rear end of the filler cartridge 50 is disposed in contact with the piston member 63, the piston member 63 is advanced while pressing the filler cartridge 50 in accordance with the operation of the operation handle 71.

이에 따라 충전재카트리지(50)의 후단부가 점차 선단부측으로 가압되어 이동되어 충전재(S)가 니들부재(30)를 통해 외부로 배출된다. Accordingly, the rear end portion of the filler cartridge 50 is gradually pressed to the front end side, and the filler S is discharged to the outside through the needle member 30.

도 2에 도시된 충전재카트리지(50)는 내부에 수용된 충전재(S)가 거의 모두 배출되어 피스톤부재(63)가 선단부로 완전히 전진이동된 상태이다. 충전재카트리지(50) 내부에 충전재(S)가 모두 소진된 경우에는 도 2의 상태에서 피스톤부재(63)가 뒷쪽으로 후진된 상태로 배치된다. Filler cartridge 50 shown in Figure 2 is a state in which almost all of the filler (S) accommodated therein is discharged and the piston member 63 is completely moved forward to the front end. When all of the filler material S is exhausted inside the filler cartridge 50, the piston member 63 is disposed in a backward state in the state of FIG. 2.

충전재카트리지(50)는 가열유닛(20)의 인덕션코일(24)에 의해 가열될 수 있도록 금속소재로 형성된다. 즉, 인덕션코일(24)이 1차권선으로 작용하여 내부에 흐르는 전류의 흐름에 의해 자기장이 유도될 수 있는 2차권선 역할을 하는 금속소재로 충전재카트리지(50)는 형성된다. 이 때, 충전재카트리지(50)를 형성하는 금속소재의 저항에 의해 발열효율이 상이해지므로 충전재카트리지(50)의 크기와 인덕션코일(24)의 형상 등을 고려하여 적절한 것으로 선택하는 것이 바람직하다. The filler cartridge 50 is formed of a metal material so as to be heated by the induction coil 24 of the heating unit 20. That is, the filler cartridge 50 is formed of a metal material serving as a secondary winding in which the induction coil 24 acts as a primary winding and a magnetic field can be induced by a current flowing therein. At this time, since the heat generation efficiency is different depending on the resistance of the metal material forming the filler cartridge 50, it is preferable to select a suitable one in consideration of the size of the filler cartridge 50 and the shape of the induction coil 24.

회전유닛(40)은 가열유닛(20)의 후단부에 결합되어 가열유닛(20)과 함께 회전된다. 회전유닛(40)은 상부하우징(13) 내부에 회전가능하게 설치되며, 내부는 피스톤부재(63)가 수용되도록 중공형상을 갖는다. 결합부재(27)에 의해 가열유닛(20)과 결합된 상태로 위치가 고정되고, 이 상태에서 전원이 인가되면 구동모터(미도시)의 구동력에 의해 회전된다. The rotary unit 40 is coupled to the rear end of the heating unit 20 is rotated together with the heating unit 20. The rotary unit 40 is rotatably installed in the upper housing 13, and has a hollow shape to accommodate the piston member 63. The position is fixed in the state coupled with the heating unit 20 by the coupling member 27, when the power is applied in this state is rotated by the driving force of the drive motor (not shown).

회전유닛(40)의 회전구동방식은 기 출원된 공개특허 10-2010-0006112호와 동일하므로 자세한 설명은 생략한다. Rotation driving method of the rotation unit 40 is the same as the previously published Patent Application No. 10-2010-0006112, detailed description thereof will be omitted.

피스톤유닛(60)은 작동손잡이(71)의 작동에 의해 충전재카트리지(50)를 가압하여 충전재(S)가 니들부재(30)를 통해 배출되도록 한다. 피스톤유닛(60)은 작동손잡이(71)와 연동되는 연동부(75)에 결합된다. 피스톤유닛(60)은 충전재카트리지(50)를 가압하는 피스톤부재(63)와, 피스톤부재(63)를 탄성적으로 초기위치로 복귀시키는 리턴스프링(65)을 포함한다. 피스톤부재(63)의 후단부에는 수동으로 피스톤부재(63)를 가압하는 수동손잡이(61)가 구비된다. The piston unit 60 pressurizes the filler cartridge 50 by the operation of the operation knob 71 so that the filler S is discharged through the needle member 30. The piston unit 60 is coupled to the linking portion 75 which is interlocked with the operation handle 71. The piston unit 60 includes a piston member 63 for pressing the filler cartridge 50 and a return spring 65 for elastically returning the piston member 63 to an initial position. The rear end of the piston member 63 is provided with a manual handle 61 for manually pressing the piston member 63.

작동부(70)는 피스톤유닛(60)이 충전재카트리지(50)를 가압하도록 한다. 작동부(70)는 작동손잡이(71)와, 가압스위치(73)와, 작동손잡이(71)의 가압을 피스톤유닛(60)의 직선이동으로 전달하는 연동부(75)를 포함한다. The operation unit 70 allows the piston unit 60 to pressurize the filler cartridge 50. The operation unit 70 includes an operation knob 71, a pressure switch 73, and an interlocking unit 75 for transmitting the pressure of the operation knob 71 to the linear movement of the piston unit 60.

작동손잡이(71)는 손잡이하우징(11)에 회동가능하게 결합된다. 작업자가 작동손잡이(71)를 손잡이하우징(11) 측으로 가압하면 피스톤유닛(60)의 피스톤부재(63)가 전진구동하여 충전재카트리지(50)를 가압하게 된다. 작동손잡이(71)와 피스톤부재(63)는 연동부(75)에 의해 연결된다. The operating handle 71 is rotatably coupled to the handle housing 11. When the operator presses the operation handle 71 to the handle housing 11 side, the piston member 63 of the piston unit 60 drives forward to pressurize the filler cartridge 50. The operating handle 71 and the piston member 63 are connected by an interlocking portion 75.

가압스위치(73)는 가열유닛(20)의 온/오프 동작을 제어한다. 가압스위치(73)의 가압여부에 따라 배터리(12)의 전원이 가열유닛(20)의 인덕션코일(24)로 공급된다. The pressure switch 73 controls the on / off operation of the heating unit (20). The power of the battery 12 is supplied to the induction coil 24 of the heating unit 20 depending on whether the pressure switch 73 is pressurized.

이러한 구성을 갖는 본 발명에 따른 치과용 충전기(1)의 작동과정을 도 1 내지 도 5를 참조하여 설명한다. The operation of the dental charger 1 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 5.

작업자는 외부케이싱(21)을 분리한 후 충전재(S)가 충진된 새로운 충전재카트리지(50)를 가열유닛(20) 내부로 삽입한다. 충전재카트리지(50)의 삽입에 의해 피스톤부재(63)는 뒷쪽으로 밀리게 된다. After removing the outer casing 21, the worker inserts a new filler cartridge 50 filled with the filler material S into the heating unit 20. By inserting the filler cartridge 50, the piston member 63 is pushed back.

충전재카트리지(50)를 충전기본체(10) 내부에 결합시킨 후 외부케이싱(21)을 상부하우징(13)에 결합시킨다. 그리고, 가압스위치(73)를 가압하면 배터리(12)의 전원이 인덕션코일(24)로 전달된다. 전원의 공급에 따라 도 5에 도시된 바와 같이 인덕션코일(24) 내부로 전류가 흐르게 되고, 충전재카트리지(50) 내부로 전류 흐름과 반대방향의 자기장이 형성된다. After the filler cartridge 50 is coupled to the inside of the charger body 10, the outer casing 21 is coupled to the upper housing 13. When the pressure switch 73 is pressed, the power of the battery 12 is transmitted to the induction coil 24. As shown in FIG. 5, a current flows into the induction coil 24, and a magnetic field in the opposite direction to the current flow is formed inside the filler cartridge 50.

자기장의 형성에 따라 열이 발생되어 충전재카트리지(50) 내부의 충전재(S)가 가열되며 열화된다. 이 때, 인덕션코일(24)이 감겨있는 충전재카트리지(50)만 가열되므로 외부로 열이 전달되지 않아 열손실이 없고 환자의 구순 등에 외부케이싱(21)이 접촉되더라도 안전할 수 있다. As the magnetic field is formed, heat is generated so that the filler S inside the filler cartridge 50 is heated and deteriorated. At this time, since only the filler cartridge 50 in which the induction coil 24 is wound is heated, no heat is transmitted to the outside, so that there is no heat loss and it may be safe even if the outer casing 21 contacts the patient's mouth.

작업자가 작동손잡이(71)를 가압하면 연동부(75)의 동작에 의해 피스톤부재(63)가 전진하면서 충전재카트리지(50)를 가압하여 내부에 수용된 충전재(S)가 니들부재(30)로 유입된 후 환자의 구순으로 공급된다. When the operator presses the operation handle 71, the piston member 63 advances by the operation of the interlocking portion 75 and presses the filler cartridge 50 so that the filler S contained therein flows into the needle member 30. And then supplied to the patient's labia.

이 때, 충전재(S)는 충전재카트리지(50) 표면에서 인덕션히팅방식에 의해 가열되므로 연화되어 공급된다. 한편, 가열유닛(20)은 회전유닛(40)에 연동하여 회전하게 된다. At this time, since the filler (S) is heated by the induction heating method on the filler cartridge 50 surface is softened and supplied. On the other hand, the heating unit 20 is rotated in conjunction with the rotary unit 40.

이상에서 살펴본 바와 같이 본 발명에 따른 치과용 충전기는 인덕션히팅 방식에 의해 충전재카트리지를 가열하게 되므로 외부 열손실이 적어 열효율이 증가될 수 있다. 또한, 충전재카트리지만 가열하게 되므로 다른 구성들로 열이 전달되지 않아 환자의 구순에 접촉되더라도 안전하게 사용할 수 있다. As described above, since the dental charger according to the present invention heats the filler cartridge by the induction heating method, the thermal efficiency may be increased due to less external heat loss. In addition, only the filler cartridge is heated so that heat is not transferred to other components, so that it can be used safely even if the patient is in contact with the labia.

또한, 외부 조건에 관계없이 일정하게 열이 발생되므로 충전재를 일정한 온도로 가열할 수 있다. In addition, since the heat is constantly generated regardless of external conditions, the filler can be heated to a constant temperature.
