Control device for home heated blood promotion / pain treatment device

The present invention relates to a control device of a home heat blood promotion / pain treatment device that simultaneously releases negative ions, heat and far infrared rays to promote blood circulation in the human body and physically treat pain of a patient.

In general, there is a utility model publication No. 92-2395 published in Korean Utility Model Publication No. 1578 as a control device of the conventional electric cushion. The control device disclosed in the Utility Model Publication discloses a slide switch SW ₁ having one end terminal of a plug 1 to which an AC power source AC is input connected to the fixed terminals C and D 'of the temperature controller 2. The fixed terminals B and C 'are connected to the fixed terminal E' where one side of the cathode of the diode DA and the bimetal switch SW ₂ are coupled to each other through the heating element R ₁ , but the diode DA Is connected to the fixed terminal (D) of the slide switch (SW ₁ ) and the other terminal of the bimetal switch (SW ₂ ) is the other terminal of the plug (1) through the temperature fuse (F ₁ ) and the heater wire (H) Is connected to.

Temperature controller (2) is exposed to the outside of the mugwort steaming bag (10) for example electric cushion so that the user can easily control the temperature, the first AC power to the plug (1) to use the mugwort steamer (10) as input AC) a slide switch (SW ₁₎ to the off state means that the slide switch (SW _1), a fixed terminal (a, B) (a ' , B') and the temperature control of the thermostat (2) in a connected state raising a first step of the step, it is connected to the fixed terminals (B, C) (B ' , C') of the slide switch (SW _1).

At this time current is fixed terminals (B, C) of the heat generating elements (R ₁₎ a through the bimetal switch (SW ₂₎ the heat-generating element to be applied in accordance with the jeohangga of heat generating elements (R ₁₎ a (R ₁₎ through heating, the detected temperature of the bimetallic switch (SW ₂₎ is automatically turned off as early as the off-set temperature of the bimetal switch (SW ₂₎ to prevent the overheating of the ssukjjim (10)

The first step of the temperature control step is to set the temperature of the mugwort steamer 10 to a relatively low temperature of about 40 ℃, the off-set temperature of the bimetal switch is set to a relatively high temperature of about 70 ℃.

Therefore, in the first stage of temperature control, since the set temperature of the mugwort steamer 10 is low, the set temperature is reached faster than other stages with the same power, and thus the sensing temperature of the bimetal switch SW ₂ is also set to the off set temperature. In order to reach quickly, select a heating element having the required heating amount.

In this state, when the slide switch SW ₁ is raised to the second stage of temperature control, the slide switch SW ₁ is connected to the fixed terminals C and D (C 'and D') to fix the fixed terminals C and D. Power is supplied to the heating element R ₁ and the bimetal switch SW ₂ through C ′, D ′ and the diode DA so that the power is passed through the diode DA so that the heating amount of the heating element R ₁ is increased. Is reduced to ½ compared to the first stage.

Accordingly, the temperature of the heating element (R ₁ ) detected by the bimetal switch (SW ₂ ) is relatively lower than the first stage, so that the time to reach the off-set temperature of the bimetal switch (SW ₂ ) is delayed, the mugwort steamer (10) ) Is sufficiently reached in the two-stage set temperature, so that the time to reach the set temperature of the mugwort steamer 10 and the time to reach the off set temperature of the bimetal switch SW ₂ by the heating element R ₁ are almost identical.

And finally, to control the temperature in the third step, when the slide switch (SW ₁ ) is connected to the fixed terminals (D, E) (D ', E'), current is applied directly through the bimetal switch (SW ₂ ). Since the current flows to the heater wire H through the temperature fuse F ₁ and no current flows in the heating element R ₁ , the bimetal switch SW ₂ continues to the heater wire H until its off set temperature is reached. By applying a current, the mugwort steaming bag set temperature of the third step is made to coincide with the off set temperature of the bimetal switch SW ₂ .

However, the conventional electric cushion control device configured as described above is not only inconvenient to use because it can not generate heat only in a part of the cushion, and also does not save energy for use, and also can not generate negative ions to treat blood circulation and patient pain. There was no problem.

The present invention has been made in view of the above-mentioned various problems, and an object of the present invention is to promote domestic heat-promoting blood, which can control the release of heat, far-infrared and negative ions in at least a portion of household heat-promoting blood / pain treatment device that heats the human body. / To provide a control device for pain therapy.

Since a current flows through the light emitting diode D20 of the sensor PC1, the light emitting diode D20 of the first optical sensor PC1 emits light. Accordingly, the diaak T20 of the first optical sensor PC1 is operated to trigger the triac 302 of the first switching means 300 to fix the movable contact a1 and the fixed contact of the blocking means 330. And it is applied to the second heating wire 111b through the triac 303 and starts to generate heat.

The control signal inputted to pin 2 of the second transistor array 290 through pin 7 of the controller 270 is amplified and outputs an output control signal from pin 15, thereby providing a second voltage through the current limiting resistor R19. Since a current flows through the light emitting diode D21 of the optical sensor PC2, the light emitting diode D21 of the second optical sensor PC2 emits light. Accordingly, the diaak T21 of the second optical sensor PC2 is operated to trigger the triac 303 of the second switching means 310 so that the movable contact a1 of the blocking means 330 is fixed. In contact with the power source, power is applied to the second heating wire 111b through the CM1 terminal, the movable contact a1 of the blocking means 330, the fixed contact point, and the triac 303, and starts to generate heat.
