Description

TECHNICAL FIELD [0001] The present invention relates to a radiating frequency cutoff function of a dental public heating device,

Field of the Invention The present invention relates to a scraper heating apparatus for dental use in a wax processing process for manufacturing a denture or a dental prosthesis in a dental bottle / clinic, and more particularly, The present invention relates to a heating device for a dental carving furnace equipped with a function.

As is well known, in order to use a sculpture tool for dental use, the tip of the sculptural figure is heated by an alcohol lamp or the like.

In the course of the work, the worker firstly heated the wax to a suitable temperature in consideration of the type of wax and the tip size of the piece.

As mentioned above, depending on the senses, the worker who does not have skilled functions is inconvenient to heat and work properly.

Particularly, when the sculptural figure is overheated, the physical properties of the wax may change, and pore work may be impossible or erroneous, and the heating temperature may become non-uniform, and thus it may be heated in a state unsuitable for molding synthetic resin of wax or preparation of wax for dental prosthesis preparation .

In recent years, a heating apparatus using heat or other heat source has been developed. However, it is a matter of course that an appropriate and uniform heating time is required to obtain an appropriate temperature depending on the type of the wax and the shape of the wax, If the synthetic resin of the denture melts and the work is wrong or the wax is machined, if the wax is overheated, the work may be erroneously flowed. If the wax is not heated to the extent necessary for machining, there is a problem that the machining condition is poor and reheating is required from time to time.

In the case of a device in which heating is started when the tip end of the piece is detected by the proximity sensor by the proximity sensor method, if the size of the tip is too large according to the shape of the piece, the detection does not proceed to the proper depth. Or if it is too small, it will not be detected even if it has reached a sufficient depth and it will not be heated, which will cause obstacles to work. If you repeatedly perform dental porcelain work and heating work, The detection and heating are irregularly performed, which results in a disadvantage that a great deal of work is interrupted.

In order to solve the above-mentioned disadvantages, Patent No. 10-1022741, filed by the applicant of the present application, and a sculpture heating apparatus for dental use are available. However, since it is a high frequency induction heating system, There is a problem that a malfunction occurs frequently due to influence or influence of other equipment due to the generated radiation frequency.

The present invention provides a device for heating a sculpture for dental use, comprising: a means for inserting a tip portion of a sculpture and simultaneously having a heating recess for performing a heating operation for a predetermined time in a high-frequency induction manner, And a means for expressing the operation sound of the lighting device during the heating action, and a high frequency heating circuit portion having a high frequency oscillation circuit for heating the tip is formed therein, A tip detection circuit part having a proximity induction frequency oscillation circuit and a control part composed of an electronic relay and a switching diode transistor resistor, in particular, a pedestal detection sensor is installed in the heating port in order to cut off the radiation frequency generated when the heating port is operated to heat the piece, It is seen that it is connected with It is characterized by the invention.

The heating apparatus (1) of the present invention is configured in the form of a heating port (2) having a concave shape in a downwardly inclined direction from the front side.

A seven-segment numeric display device (3) is arranged at an arbitrary position in the vicinity of the heating port (2) so that the setting step can be represented by a number.

A time setting button 4 for setting the heating time and a sensitivity for setting the sensitivity of the tip 101 of the piece 100 entering the heating port 2 are set around the heating port 2 And a setting button (5), and an operation indicator lamp (6) is formed around the heating port (2).

The high frequency heating circuit unit 20, the tip detection circuit unit 30, the power supply and the switch circuit unit 40, the input and sensing unit 30, (50), and a numeric display unit (60).

The high frequency heating circuit unit 20 includes an output control unit 21 for controlling the heating operation in response to a command from the control device 10, a work coil drive circuit 22, a high frequency oscillation circuit 23, a TANK circuit 24 And a work coil 25. As shown in Fig.

The operation display lamp 6 is connected to the output control unit 21 through the heating unit 4 and the heating unit 5, And the buzzer 7 is connected to the output control unit 21 at the same time to generate a buzzer sound when the heating is started and when the heating is completed.

The tip detection circuit section 30 is constituted by the detection coil section 31 and the proximity detection circuit 32 and the proximity induction oscillation circuit 33 and transmits the detection signal to the control section 10 through the small signal amplification section 34 , And operates according to the set detection intensity.

The input and sensing unit 40 is constituted by a heating time setting unit 51 which is operated by the time setting button 4 and which sets the operation time to the control device 10, And a detection sensitivity setting section 52 that controls the proximity sensitivity of the tip detection circuit section 30 while being operated by the detection sensitivity setting section 52. [ The heating time setting unit 51 and the detection sensitivity setting unit 52 are set to 1 to 9 steps and are set to rise by one step each time the time setting button 4 or the sensitivity setting button 5 is pressed do.

The control unit 10 is connected to a temperature detection unit 11 to detect the temperature around the heating port 2. When the detected temperature is excessive, the fan is driven to drive the fan through the fan motor driving circuit unit 12 Respectively.

In the control device 10, a numeral display circuit 61 is arranged in the numeric display section 60 to display the numerical value set through the numeral display device 3.

Particularly, in order to block the radiation frequency generated when the heating port is operated in order to heat the piece, the heating port 2 is provided with a piece detection sensor 25 ', and the electronic relay 200, the switching diode 201, And a control file ratio 203 constituted by a resistor 202, as shown in FIG.

The operation of the present invention having such a configuration will be described in detail in accordance with the method of use.

First, after the power is applied, the time setting button 4 is operated to set the required heating time according to the kind of the wax to be used. Since the melting point is different depending on the type of the wax, To obtain a desired temperature. The set time is input to the controller 10 to control the operation of the output controller 21 and to control the heating operation only for the set heating time.

Sensitivity is set according to the size of the tip 101 of the piece 100 to be used by operating the sensitivity setting button 5. This is because the sensing position is changed according to the size of the tip 101, If the size of the tip 101 is small, it is not sensed even when the tip 101 is fully inserted, and heating is not started. In this case, the sensitivity is increased. It should be given.

The set sensitivity is input to the control device 10 and senses the sensed degree of the intense width portion 34 with a predetermined sensitivity.

In the process of setting the temperature and the sensitivity, a number set by the numeric display device 3 is displayed while the numeric display circuit 61 of the display unit 60 is driven.

When the tip 101 of the piece 100 to be used is inserted into the heating port of the heating apparatus 1, the tip detection circuit unit 30 senses the sensed sensitivity and senses the output of the high frequency heating circuit unit 20 The control unit 21 operates for a predetermined amount of time and the tip is heated while the work coil 25 radiates heat until the heating of the operation indicator lamp 7 and the buzzer 7 is completed .

When the heating is completed, the operation indicator lamp 7 is turned off and the operation sound of the buzzer 7 is stopped. Thus, the operator can easily recognize the completion of the heating operation. When the wax is melted and attached to the tip 101, the wax is buried in the tooth to be treated, the artificial tooth or the denture.

If the temperature of the tip after one use falls below a certain level, the heating operation is repeated again and the wax is again buried in the tip 101 to perform the operation.

When the tip 101 of the sculptural figure 100 entering the heating port 2 is detected during the above operation, the detection signal of the sculptural figure detection sensor 25 'is blocked at the moment the tip 101 of the sculptural figure 100 is detected, The coil 25 is operated to heat the tip of the piece.

When the tip 101 of the piece 100 entering the heating port 2 is heated to an appropriate temperature and taken out from the heating port 2, the tip 101 is operated to operate the work coil 25 of the heating port 2 .

Therefore, it is possible to prevent the drive voltage generated during the work coil drive from affecting the input circuit of the crushing detection sensor 25 'through the work coil and malfunctioning.
