Description

[Detailed Description of the Invention] This invention relates to an ultrashort wave therapy device that performs 7i'l therapy by transmitting ultrashort waves to the human body, and more specifically, when a conductor is not connected, the oscillation operation automatically stops when +S<Super'), related to G-wave therapy equipment.

An ultrashort wave treatment device that uses ultrashort waves to treat the human body,
It is currently widely used because ultra-710 wave therapy can be performed in the home at home. FIG. 1 is a block diagram showing the configuration of a conventional ultrashort wave treatment device.

] or 2 turns, (! Wave opening) = 1 coil (called a coil in both hands) 8, J3 and a cover 9 that covers the coil 8, and the code 7a, 7b. The output terminals 10a and 10b of the ultra-high frequency generating circuit 3 are connected to each other.In this case, the oscillation frequency of the ultra-high frequency generating circuit 3 is adjusted according to the state in which the conductor 6 is connected. Synchronization is maintained.

By the way, when the conductors 6 are not connected to the output terminals 10a and 10b, the zero load impedance of the very high frequency generating circuit 3 is approximately infinite, and the oscillation frequency is out of tune. When the power switch 5 is turned on in such a state, in the above-mentioned conventional ultrashort wave treatment device J3, an abnormal vibration occurs due to out of synchronization, and the surrounding (shallow type) This has caused problems such as negative effects such as noise.Furthermore, when the VHF generator circuit 3 is activated in an out-of-tuning state, the loss of the circuit's output stage 1 to the transistors increases. In a treatment device, assuming the case (a) above, the radiator and mounting space for the transistor in the output stage 1 must be set large enough to allow for a large margin, making it difficult to miniaturize the device. There were drawbacks.

In view of the circumstances stated above, the present invention provides a 0-wave treatment device that can prevent the occurrence of paranormal vibrations, and can also reduce the size of the device. The present invention is characterized by being equipped with a protection circuit that detects whether or not a conductor is connected to the output terminal of the circuit and prohibits the operation of the single wave generation circuit when the conductor is not connected.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows the first embodiment of the present invention (j.1 configuration).

It is complete. d5 and capacitor C2 are smoothing capacitors.

Next, the operation of the protection circuit 15 will be explained.

i) When the conductor 6 is connected to the output terminals 10a and 10b.

In this case, when the power switch 5 is turned on, a current flows through the path of resistor R2→R3→[output terminal 10a→coil 8→output terminal 101), and the base potential of transistor Q2 decreases. As a result, base current flows through transistors 1 to Q2, turning transistor Q2 off. When the transistor Q2 turns on, the one-wavelength transistor Q1 turns on, and as a result, current is supplied from the transistor Q1 to the very high frequency generating circuit 3 via the resistor R1, and the very high frequency generating circuit 3 starts operating. Therefore, ultrashort waves are supplied from the output terminals 10a and 10b to the conductor 6,
In response to this, ultrashort waves are radiated from the coil 8. In this case, a high resistance is used for the resistor 1 and 4 so as not to affect the operation of the microwave generating circuit 3, and the value of the capacitor C3 is set to a value that bypasses the microwave component.

ii) When the 49 child 6 is not connected to the output terminals 10a, 10b.

In this case, even if the power switch 5 is turned on, the resistor R2,
Since no current flows through Ra and Ra, the transistor Q2
always remains in the off state, and as a result, the 1-transistor Q+'b:4 maintains the off state.

Therefore, the ultrahigh-frequency generating circuit 3 maintains a non-operating state since no current is supplied thereto, and no parasitic vibration is generated.

In addition, as mentioned above, 7. : If the conductor 6 is removed from the state i), the state ii) described above will occur, and the very high frequency generating circuit 3 will immediately stop operating.

FIG. 3 is a circuit diagram of a modified example of this embodiment.

This modification is an example in which a coil 8, a heater (not shown), and a temperature regulator 12 such as a thermistor that feeds back heater depletion are provided inside the cover 9- of the conductor 6'. In this case, both ends of the sensor 12 are connected to the terminals 14a and 14b via cords 13a and 13b, respectively, and the conductor 6- is connected to the four conductors on the right side. ing. Mata, code 7a, 7b, 1

011, 14a, and 141+ at the same time.

Therefore, when the conductor 6' is connected to the prong terminals 10a, 10b and the terminals 14a, i4b, the resistor R2-
Since the current flows along the path R3-→R4→Ren 1 to 12, this corresponds to the case 1) of the above-described embodiment, and the very high frequency generating circuit 3 is in the operating state. On the other hand, when the conductor 6' is not connected, this corresponds to the above-mentioned case, and the very high frequency generating circuit 3 does not operate. However, resistive elements provided within the conductor for other purposes may also be utilized in the practice of the present invention.

d3, the same effect can be obtained even if a simple jumper wire (similar to m wire) is used in place of the sensor 12 in this modification.
can be done.

FIG. 4 is a circuit diagram showing the configuration of a second embodiment of the present invention, and parts corresponding to those in FIG. 2 are given the same reference numerals.

In this second embodiment, the conductor 6 is the output terminal 10a.

If the power switch 5 is turned on without being connected to the power source 10b, the operation of the very high frequency generation circuit 3 is prohibited and the alarm sound is emitted. , 21, resistance R+o・Ru・
Condenser 4IC4J3 and piezoelectric optical sound body 22k, lfi
, constitutes the alarm circuit 23.

The operation of this embodiment will be explained below.

a) When the conductor 6 is connected to the output terminals 10a and 10t+.

In this case, when the power switch 5 is turned on, a current flows through the path C, which is the output terminal 10b of the resistor (dog 2 → R3 → R4 → output terminal 10a → coil 8-), and the transistor Q3
turns on. As a result, transistor Q3 → resistor RI2
Current flows through the path, raising the base potential of transistor Q4 and turning transistors Q4 and Q5 off. 1. When transistor Q4 turns off, diode D+ becomes forward biased, and resistor R+s → die A.
A current flows through the path from - node D1 to resistor R13, and the base potential of transistor Q2 decreases. As a result, base current flows through transistors 1 to Q2, turning them off, and at the same time transistor Q+ turns on.

In response to this, power is supplied to the very high frequency generating circuit 3 via the resistor R1, and the circuit starts operating. On the other hand, when the transistor Q5 is turned off, no current flows through the resistor R14, and one input terminal of the Nant gate 20 becomes II L
It becomes I+ level. As a result, the output terminals of the Nandogoos 1-20 are fixed at the 'li-i' level, and furthermore, the output terminals of the Nandogoos 1-21 are fixed at the level of li L II. Since the voltage applied to the piezoelectric sounding body 22 does not change,
stomach. Na J3, Nandogoo 1-20.21, resistance R+o,
Rn and capacitor C4 constitute a two-oscillation circuit as shown in FIG.

b) When the conductor 6 is not connected to the output terminals 10a and 10b.

In this case, when the -r7Ui source switch 5 is turned on, no current flows through the resistors Rz, R:+, and R4. Therefore, in the case of a) above, the transistor Q3 is turned off and the transistor Q4 is turned off. , Q5 turns on.

Then, when transistor Q4 turns on, diode 01 becomes reverse biased, the base potential of transistor Q2 rises, and transistors Q2 and Ql turn off. Therefore, the very short wave generating circuit 3 is not supplied with power and becomes inactive. On the other hand, when the transistor Q5 is turned on, one input terminal of the Nandogs 1 to 20 is "'"
l-1” level, Nandogu-1~20.21,
An oscillation circuit consisting of resistors R1G, Ro, and capacitor C4 operates, and piezoelectric sounding body 22 makes a sound. Therefore, the user can know from the sound that the conductor 6 has come off. In this embodiment, the sounding body 22 is used as the alarm means in J3, but instead of this, an optical alarm means that lights up a light emitting diode or the like may be used.

As explained above, according to the present invention, it is possible to detect whether or not a conductor is connected to the output terminal of a very high frequency generation circuit,
Since it is equipped with a protection circuit that prohibits the operation of the ultrahigh frequency generation circuit when the conductor is not connected, parasitic vibration will not occur even if the device is powered on with an Ω source with no conductor connected. : There is no need to worry about any negative impact on surrounding equipment. Further, since the loss of the output stage transistor of the very high frequency generation circuit does not increase, the heat sink of the output stage transistor can be small, and the advantage that the device can be miniaturized is increased. In addition, if the conductor is not connected properly, an alarm can be issued to alert the user, which is more convenient.
