Description

[Detailed explanation of the idea] The present invention relates to an electric moxibustion device.

Generally, when symptoms such as stiff shoulders or neuralgia occur, the treatment is usually to use a moxibustion device to warm the affected area and improve blood circulation.

In this case, when a moxibustion device heated to around 60°C to 80°C is applied to the affected area of the skin, the heat from the high temperature becomes unbearable within a few seconds, and the person instinctively removes the moxibustion device from the affected area.

However, some people can withstand use for several minutes at temperatures of around 45°C to 55°C, and in this case, if the moxibustion device is brought into continuous contact with the skin, human skin may suffer from low-temperature burns at temperatures of 45°C to 55°C. Burns may be noticed later.

The present invention aims to eliminate the above-mentioned drawbacks and provide an electric moxibustion device that does not cause low-temperature burns even when the moxibustion device is continuously used in contact with the affected skin.

Next, the electric moxibustion device of the present invention will be explained with reference to the drawings.

In the figure, reference numeral 1 denotes a case body of an electric moxibustion device formed in a substantially cylindrical shape, and a pipe-shaped guide 2 having a smaller diameter than the case body and extending in the longitudinal direction projects from one end thereof.

The inside of the guide 2 is hollow, and a substantially spherical bulging head 3 is provided at the tip, and a recessed chamber 4 is formed inside the head 3.

The recessed chamber 4 is integrally connected to the cavity within the kite 2, and a heating head 5 for warming the affected area is slidably provided within the recessed chamber 4.

The heating head section 5 includes an electrode plate 7 attached to the tip of a thermally conductive electrode rod 6 made of, for example, aluminum, a ceramistor 8 which is a heating element that transmits heat to the electrode plate 7, and the electrode plate. 7 and an insulating cloth 9 covering the outer surface of the ceramistor 8.

Reference numeral 10 denotes an insulating pipe attached to the electrode rod 6, and the ceramister 8 is attached around the tip of the insulating pipe.

Reference numeral 11 denotes an electrode pipe attached to the insulating pipe 10, and its tip is electrically contacted with the lower part of the ceramistor 8.

The other end portions of the electrode rod 6, the insulating pipe 10, etc. are coupled to a bimetal 13 that is engaged and locked in a recess of a protrusion 12 provided in the electromoxibustion device case body 11.

Reference numeral 14 denotes a microswitch, and this microswitch is provided with a switch opening/closing member 15 that opens and closes the switch in response to the bending of the bimetal 13.

In the illustrated case, the microswitch 14 is in a state where the current flowing through the microswitch is on when the switch opening/closing response member 15 is in a position away from the main body of the microswitch 14, that is, in the position shown by the solid line.
Further, when the microswitch 14 is in a pressed position due to the bending action of the bimetal 13 (indicated by a broken line), the current is turned off.

Reference numeral 16 denotes a power supply lead wire, one lead wire 17 is electrically connected to the end of the electrode rod 6 through a fuse 18 by, for example, soldering, and the other lead wire 19 is connected through a microstrip 14. , are electrically connected to the electrode pipe 9 in the same manner as described above.

Reference numeral 20 indicates a power switch, and 21 indicates a power switch.

Next, the operation of the electric moxibustion device of the present invention will be explained.

When the power switch 21 is turned on, the current flows through the lead wire 17 →
The flow flows from the fuse 18 → electrode rod 6 → electrode plate 7 → ceramister 8 → electrode pipe 11 → lead wire 19 → micro switch 14, and the heating head 5 that is brought into contact with the affected area does not get burned due to the heat generation action of the ceramister 8. It is heated to a constant temperature of, for example, 45°C to 55°C.

When the head 5 applied to the affected area is heated for a predetermined time and reaches a predetermined temperature, the heat of the heating head 5 is transferred to the bimetal 13 via the electrode rod 6 made of a thermally conductive material such as aluminum. be done.

When the bimetal 13 is heated and reaches a predetermined temperature, it curves toward the microswitch as shown by the broken line in the figure.

As a result, the electrode rod 6 in contact with the bimetal 13 and the heating head 5 provided at the tip of the insulating pipe 10 are drawn into the bottom of the concave chamber 4 in the head 3 and separated from the affected area. Prevent low temperature burns.

As the bimetal 13 bends, the switch opening/closing response member 15 provided on the microswitch 14 is pressed toward the main body of the microswitch 14 as shown by the dotted line in the figure, and at this time the microswitch 14 is turned off. state.

Therefore, the heating head section 5 is no longer heated, and the temperature of the bimetal 13 decreases.

When the temperature drops to a predetermined temperature, the bimetal 13 bends and restores its original state as shown by the solid line in the figure.

The electrode rod 6, insulating pipe 11, etc. connected to the bimetal 13 are pushed upward as the bimetal 13 is restored, and the heating head 5 provided at the tip slides from the bottom of the concave chamber 4. then touch the affected area again.

When the bimetal 13 is restored, the switch opening/closing response member 15 moves away from the microswitch 140 main body side as shown by the solid line in the figure due to the action of, for example, a return spring provided inside the microswitch 14 and returns to its original position. to return to.

Since the microswitch 14 is configured so that a current flows when the microswitch 14 is in this state, the heating head 5 that is in contact with the affected area is heated again.

FIG. 2 shows another embodiment of the electric moxibustion device according to the present invention.

In the figure, 31 is the case body of the electric moxibustion device, and 32 is a substantially single-shaped bushing button, which is slidably arranged in a recessed chamber 33 formed in the case body of the electric moxibustion device. A button portion 32' extending in the longitudinal direction projects from a through hole formed in the case body 31 of the electromoxibustion device.

Reference numeral 34 denotes a compression spring, which is disposed in the recessed chamber 33 inside the electromoxibustion device case main body 31 so as to surround the button portion 32'.

Reference numeral 35 denotes an electrode rod made of a bimetallic material, and 36 an electrode rod made of a thermally conductive material such as aluminum. It can slide together with the guide 37 in a recessed chamber 38 formed therein.

Reference numeral 39 denotes a tension spring whose one end is attached to the guide 36 and the other end is attached to the end wall of the recessed chamber 38 of the electromoxibustion device case body 31.

However, the above-mentioned bimetal 35 is different from the button 32.
A compression spring 34 and a guide 37 are sandwiched between the end 32a of the button 32 and the end of the electrode rod 36, and are provided on the bush button 32.
By the action of a tension spring 390 attached to the electromoxibustion device case body 31, the electromoxibustion device is held in pressure contact within the recessed chamber 40 formed within the electromoxibustion device case body 31.

Reference numeral 41 denotes a heating head section, which is comprised of a ceramistor 32, which is a heating element, attached to the tip of an electrode rod 36, and an electrode plate 33, which absorbs the heat of the ceramistor and heats it.

44 is a microswitch, and this microswitch is provided with a switch opening/closing response member 45. When the response member 45 is located away from the microswitch main body 44 (as shown by the solid line), the microswitch is in an off state. Become.

Further, when the responsive member 45 is pressed toward the microswitch main body 44 (as shown by the broken line) due to the operation of the protrusion 37' having a tapered slope provided on the guide 37, the microswitch is turned on. It is configured.

46 is a power supply lead wire, one lead wire 47 is electrically connected to the electrode plate 33 by, for example, soldering, and the other IJ-power wire 48 is connected to the electrode rod 36 via the microswitch 44 as described above. They are electrically connected in a similar manner.

49 indicates a rubber bushing. Next, the operation of another embodiment of the electric moxibustion device according to the present invention will be explained.

First, when the button 32' of the bush button 32 is pressed by hand, the heating head section 41 is pushed out from the electric moxibustion device case body 31 and comes into contact with the affected area.

In this case, when button 32' is pressed, the bimetal 3
5 is curved as shown by the broken line in the figure, and the electrode rod 3
6 is slid in the X direction.

At this time, the switch opening/closing response member 4 of the micro switch 44
5 is pressed against the protrusion 37' of the guide 37 provided integrally with the electrode rod 36, and the microswitch 44 is pressed.
is pushed out to the main body side.

As a result, the microswitch 44 is turned on, and the current flows from the lead wire 48 to the microswitch 24 to the lead wire 4.
8→electrode rod 36→ceramister 32→electrode plate 33→lead wire 47, heating head 41 in contact with the affected area
is heated to a predetermined temperature by the heat generating action of the ceramistor 32.

When the heating head 41 in contact with the affected area is heated to a predetermined temperature that does not cause burns, for example 45°C to 55°C, the heat of the heating head 41 is transferred through the thermally conductive electrode rod 36. The signal is transmitted to the bimetal 35.

When the bimetal 35 is heated and reaches a predetermined temperature, the bimetal 35 curves and returns to its original state as shown by the solid line in the figure, and the bushing button 32 also returns to its original state.

Therefore, by the action of the tension spring 39 attached to the guide 37, the heating-rad part 41 slides in the Y direction, is drawn into the electromoxibustion device case body 31, and is housed, and is removed from the affected skin. During heating, the rad portion 41 is separated.

Thus, the switch opening/closing response member 45 provided in the microswitch 44 is built into the main body of the microswitch 44.

For example, due to the action of a return spring or the like, the force of the microswitch main body is separated, the current is turned off, and heating of the heating head portion 41 is no longer performed.

As mentioned above, the electric moxibustion device of the present invention takes advantage of the fact that human skin is prone to low-temperature burns at temperatures between 45°C and 55°C, but does not cause burns within a certain range. By mechanically separating the heating head from the affected area using a bimetal when it reaches a predetermined temperature, it has the effect of preventing low-temperature burns on the affected area.
