An object of the utility model is to provide a simple structure feeds back stable intermediate frequency therapeutic instrument output electrode board temperature sampling circuit.
Description
Technical field
The utility model relates to a kind of temperature sampling circuit, and more specifically, it relates to the output electrode plate temperature sample circuit of a kind of mid-frequency treatment device.
Background technology
Mid-frequency treatment device, because electronic circuit can be relied on to form the similar effect of Chinese medicine acupuncture and massage, will be widely used in following domestic medicine. Owing to medium and low frequency therapeutic equipment many employings two electrode plate acts on human body, battery lead plate is provided with heating input interface, the temperature of battery lead plate and the pattern of vibrations when prescription Waveform Input interface provides work. For making that acupuncture or massage reach effect more true to nature, often heating electrode plates is implemented temperature control comparatively accurately, and wants the strict set temperature upper limit, to prevent user's skin burn. The control of temperature is except needing comparatively reliable and stable heating circuit, and temperature feedback circuit also will be very important.
Therefore there is a structure simple, and feed back stable temperature feedback circuit and the control of the temperature on mid-frequency treatment device battery lead plate just can be made more accurate, it may also be useful to get up more comfortable.
Practical novel content
For the deficiency that prior art exists, the purpose of this utility model is the mid-frequency treatment device output electrode plate temperature sample circuit providing a kind of structure simple feedback stable.
For achieving the above object, the utility model provides following technical scheme: the output electrode plate temperature sample circuit of a kind of mid-frequency treatment device, comprise battery lead plate and micro-chip, described battery lead plate inside is provided with thermistor, it is connected with detecting unit between described battery lead plate and micro-chip, the change in resistance of described detecting unit detection thermistor, produces temperature signal and inputs to micro-chip.
The utility model is set to further: described detecting unit comprises power supply, division module, current limliting module and Voltage stabilizing module, described temperature signal is through division module dividing potential drop, again through current limliting module to Voltage stabilizing module, described temperature signal transfers to micro-chip after Voltage stabilizing module.
The utility model is set to further: by Voltage stabilizing module ground connection between described current limliting module and micro-chip.
The utility model is set to further: described Voltage stabilizing module comprises a Zener diode and a filter capacitor, and described Zener diode and filter capacitor are in parallel.
By adopting technique scheme, the thermistor arranged in the inside of battery lead plate can according to the size of the different change self-resistances of temperature, thus produce a signal changed according to temperature variation, further by detecting unit by this Signal transmissions to micro-chip, then carry out the concrete control to temperature.Power supply can be carried out dividing potential drop by division module, and the electric current signal of gained enters Voltage stabilizing module again after current limliting module current limliting, and Voltage stabilizing module here is mainly played the effect of voltage stabilizing by a Zener diode. Signal through voltage stabilizing carries out filtering by the electric capacity with Zener diode parallel connection again, the last AD pin that just stable signal is inputed to micro-chip, such micro-chip control device just can differentiate the temperature of battery lead plate according to different signals, the height of further its temperature of adjustment, whole circuit structure is simple, and stable output signal.
Accompanying drawing explanation
Fig. 1 is the schematic circuit of the output electrode plate temperature sample circuit embodiment of the utility model mid-frequency treatment device.
Embodiment
With reference to Fig. 1, the output electrode plate temperature sample circuit embodiment of the utility model mid-frequency treatment device is described further.
The output electrode plate temperature sample circuit of a kind of mid-frequency treatment device as shown in Figure 1, comprises battery lead plate and micro-chip. Here battery lead plate is provided with battery lead plate heating input interface, prescription Waveform Input interface, power supply interface, ground interface and detecting unit interface. Battery lead plate heating input interface provides the electric energy required for battery lead plate heating, and prescription Waveform Input interface can adjust the vibrations mode of battery lead plate according to different input waveforms. In the present embodiment, battery lead plate inside is provided with thermistor, and is connected with detecting unit between battery lead plate and micro-chip. The change in resistance of detecting unit detection thermistor here, produces temperature signal and inputs to micro-chip. Including power supply, division module, current limliting module and Voltage stabilizing module in detecting unit, temperature signal is through division module dividing potential drop, then through current limliting module to Voltage stabilizing module, then temperature signal transfers to micro-chip after Voltage stabilizing module. In the present embodiment, division module is resistance R33, and its resistance is set to 5.1K Ω, and current limliting module is resistance R10, and its resistance is set to 10K Ω. Resistance R33 and R10 all adopts the paster resistance of 0805 encapsulation, it is possible to better save volume. And Voltage stabilizing module in the present embodiment comprises a Zener diode Z4 and filter capacitor C6, Zener diode Z4 and filter capacitor C6 is in parallel here. This is just by more stable for the signal that finally inputs to Chip Microcomputer A/D interface, precisely, is convenient to micro-chip and sends signal and temperature controlled accurately.
Specifically operationally, along with the change of battery lead plate temperature, the thermistor resistance of its inside changes thereupon, the power supply of its resistance and the right+5V of resistance R33 carries out dividing potential drop, and gained volts DS (when this voltage is higher than 3.3V, is stabilized in 3.3V through resistance R10 current limliting and Z4 voltage stabilizing, when lower than 3.3V, then normal voltage exports) after, then carry out filtering through electric capacity C4, finally input to the AD pin of micro-chip.
The above is preferred implementation of the present utility model, under not departing from the prerequisite of the utility model principle to those skilled in the art, it is also possible to make some modification and improvement, and these also should be considered as practical novel protection domain.
