Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description includes: treatment board 10, extensible member 20, actuator 30.
Interval electricity cut-off type temperature control device for specific electromagnetic spectrum treatment instrument as shown in Figure 1, including micro-control unit,
Voltage sampling circuit, the switching circuit for being controlled by micro-control unit, the alarm unit for being controlled by micro-control unit and setting are being controlled
The safeguard structure for treating 10 side wall of plate, when switching circuit is opened, the input power of therapeutic equipment supplies the heating device for the treatment of board 10
Electricity；Due to treatment board 10 heating method can for electromagnetic heating, infrared heating and resistance heating etc., this implementation
Heating device in example can be electromagnetic heater, infrared heater and/or heater strip etc., since electromagnetic heating, infrared ray add
Heat and resistance heating have been more mature technologies, therefore are no longer illustrated to its principle.
The 8951 of MCS-51 series, switching circuit, above-mentioned voltage sampling circuit packet can be used in above-mentioned micro-control unit
The divider resistance and sampling resistor of series connection are included, divider resistance one end is electrically connected with city, and the other end is connect with sampling resistor,
There is voltage sample point, voltage sample point and sampling resistor are not connect with divider resistance between divider resistance and sampling resistor
One end is connected to detection control unit, and detection control unit is configured to be formed into a loop voltage sampling circuit and carry out voltage to adopt
Sample, or be configured to keep voltage sampling circuit breaking, so that detection control unit adopts voltage when needing to carry out voltage sample
Sample circuit forming circuit, specifically, for example makes the one end of sampling resistor not connecting with divider resistance be connected to low level GND
On, so that the voltage sampling circuit between alternating current and low level GND be made to constitute circuit, there is electric current to flow through divider resistance and adopt at this time
Sample resistance, then passes through the voltage of measurement voltage sample point, and is according to the value relatable between divider resistance and sampling resistor
It can get line voltage, realize voltage sample.And when not needing to carry out voltage sample, detection control unit keeps voltage sample electric
Road open circuit, specifically, for example, make sampling resistor one end connect with divider resistance and low level disconnect, thus alternating current with
Voltage sampling circuit open circuit between low level GND, does not have electric current at this time and flows through divider resistance and sampling resistor, thus also not
Electric energy can be consumed；Above-mentioned switching circuit uses transistor switching circuit, and heating device is connected across triode as load
Between collector and power supply, and occupy on the circuit of triode principal current, input voltage control triode switch unlatching with close
Conjunction movement, when triode is in open state, load current is just blocked, conversely, electric current is just when triode is in closed state
It can circulate.Specifically, when Vin is low-voltage, since base stage does not have an electric current, collector also no current causes to connect
The load of collector terminal is connected to also without electric current, and is equivalent to switching circuit unlatching, triode is that victory makees in cut-off region at this time.Together
Reason, due to there is base current flowing, makes collector flow through bigger amplification electric current, therefore load when Vin is high voltage
Circuit is just switched on, and is equivalent to switching circuit closure.Transistor switching circuit is as common switching circuit, in the present embodiment
It repeats no more.
Voltage sampling circuit samples the input supply voltage of therapeutic equipment, and the sampled voltage signal electricity that will be sampled
Micro-control unit is given in pressure；Micro-control unit is after receiving sampled voltage signal voltage, by the sampled voltage signal voltage
It is compared with reference voltage signal voltage preset in micro-control unit, is greater than reference voltage in the sampled voltage signal voltage
When signal voltage, micro-control unit controls switching circuit intermittence is opened, and is less than or is waited in the sampled voltage signal voltage
When reference voltage signal voltage, micro-control unit controls switching circuit duration is opened；Micro-control unit is opened in control
Control alarm unit issues alarm signal when powered-down road intermittence is opened.
In use, the input power of therapeutic equipment accesses alternating current, when switching circuit is in the open state, input power
It is powered to the heating device for the treatment of board 10, heating device operates normally, and excitation therapy plate 10 issues oscillator signal, therapeutic equipment
It works normally；
Input power input voltage be greater than preset reference voltage when, as reference voltage be 231V (220V+5%) and
When input voltage is 242V (220V+10%), the sampled voltage signal voltage that voltage sampling circuit samples can namely be greater than
Preset reference voltage signal voltage in micro-control unit, at this time, micro-control unit controls switching circuit intermittence are opened, such as
Micro-control unit controls switching circuit is opened with the frequency of 4:1, i.e., switching circuit opens 1S after disconnecting 4s, is then disconnected
4S is so recycled, meanwhile, the buzzer that micro-control unit controls are used as alarm unit sends alarm signal and warns；
In the 1S time that switching circuit is opened, input power is powered to the heating device for the treatment of board 10, heating device fever；It is switching
In the 4S time that circuit disconnects, input power also just stops the power supply to heating device, and heating device also just no longer generates heat at this time；
And in the heating device athermic time, due to distributing for heating device heat, the temperature of heating device can namely be fallen
Come, and the power of heating device is zero in this process, in the time of heating device fever, the temperature of heating device
Rising again, the power of heating device restarts to increase, then, and during heating device intermittent fever, heating
When the temperature of device is also at the process of a circulation of " cooling-heating-cooling ", the temperature of heating device is allowed for always
It floats up and down within the scope of one, to avoid temperature excessively high the case where scalding, also avoids the feelings that heating device is burnt out
Condition；
And during above-mentioned, it is contemplated that user is possible to inadvertently contact treatment board 10 when in use, therefore,
Side wall also in treatment board 10 is provided with safeguard structure, as shown in Figures 2 and 3, treatment board 10 when the temperature is excessively high, protection
The actuator 30 of structure, that is, air bag meeting expanded by heating, so that the side wall along treatment board 10 is upheld in the horizontal direction, band
Dynamic extensible member 20 is fixed on the end motion on air bag, but due to one end of extensible member 20 be fixed on it is motionless on 10 side wall for the treatment of board
, therefore extensible member 20 stretches under the driving of air bag, blocks automatically to treatment board 10, also avoids user with treatment
The direct contact of plate 10, reduces the risk of scald, and the rubber slab of wrinkle can be used in extensible member 20 therein.
