The temperature sensor 15 is configured to detect the actual temperature of the moxibustion instrument in real time and send the obtained actual temperature to the processor.
The processor is configured to compare the detected actual temperature with a preset target temperature; monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion instrument in real time; and controlling the fan to start or stop based on the comparison of the actual temperature and the preset target temperature and the magnitude relation between the monitored heat dissipation capacity and the monitored heat supply capacity.
The device that this application provided simple structure easily realizes, and because the fan can in time respond to in time according to the actual temperature in the combustion chamber and open/stall, ensures that moxa smoke in time discharges, has avoided adsorbing in the combustion chamber because moxa oil that moxa stick burning produced causes the jamming, does not influence the normal use of moxibustion instrument.
Fig. 2 shows a flowchart of a specific embodiment of a temperature control method based on the moxibustion apparatus provided in the present application, specifically, the temperature control method includes:
step S201: the actual temperature of the moxibustion instrument detected in real time is obtained.
Specifically, the actual temperature of the moxibustion apparatus can be detected by the temperature sensor 15, and the detected actual temperature T1 is sent to the processor for subsequent judgment processing. The actual temperature value may be detected at intervals of a preset time interval, where the preset time interval may be set according to a user requirement (for example, a moxibustion mode), for example, may be detected once every 100ms to 300ms, preferably, but not limited to, 200ms.
Step S202: and comparing the detected actual temperature with a preset target temperature.
After the actual temperature is detected, the actual temperature T1 is compared with a preset target temperature T0. The preset target temperature T0 can be obtained by setting by a user or by default of the system, and the numerical value of the preset target temperature T0 meets the temperature requirements of corresponding acupuncture points or parts of a human body when the moxibustion instrument is used in a certain moxibustion mode. In other words, the preset target temperature T0 may be set to different values for different moxibustion modes. When judging this actual temperature T1 to be greater than or equal to preset target temperature T0, promptly need in time cool down the operation, control fan stall at first in this application embodiment, stop the air inlet, along with the burning of moxa stick, the oxygen content in the combustion chamber will gradually reduce, slows down the burning of moxa stick.
When the actual temperature T1 is determined to be less than the preset target temperature T0, namely, a temperature raising operation is required, in the embodiment of the present application, the fan is controlled to be turned on so as to introduce more oxygen, so that the moxa stick is fully combusted to raise the temperature.
Step S203: and monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion instrument in real time.
Step S204: and controlling the switch of the fan based on the comparison of the actual temperature and the preset target temperature and the magnitude relation between the monitored heat dissipation capacity and the monitored heat supply capacity.
According to the embodiment of the application, the actual temperature of the moxa stick detected in real time is obtained; and comparing the detected actual temperature with a preset target temperature, monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion instrument in real time, and controlling the on and off of the fan based on the comparison between the actual temperature and the preset target temperature and the magnitude relation between the monitored heat dissipation capacity and the monitored heat supply capacity. Therefore, under the condition of detecting the magnitude relation between the actual temperature and the preset target temperature, the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion instrument is further monitored, so that the fan is controlled more accurately, the rapid response to the cooling process is realized, and the adverse effect caused by temperature regulation lag is avoided.
Based on the above embodiment, a flowchart of another specific embodiment of the temperature control method of the moxibustion apparatus provided in the present application is shown in fig. 3. The method specifically comprises the following steps:
step S301: the actual temperature of the moxibustion instrument detected in real time is obtained.
Step S302: and comparing the detected actual temperature with a preset target temperature.
Step S303: and monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion instrument in real time.
Step S304: when the actual temperature is greater than or equal to the preset target temperature, controlling the fan to stop rotating;
step S305: when the heat dissipation capacity and the heat supply capacity are monitored to be equal under the condition that the fan stops rotating, the fan is controlled to be started;
step S306: further, under the condition that the fan is started, when the fact that the heat dissipation capacity is equal to the heat supply capacity and the actual temperature is greater than or equal to the preset target temperature is detected, the fan is controlled to be closed; when the heat dissipation capacity and the heat supply capacity are monitored to be equal and the actual temperature is smaller than the preset target temperature, the fan is kept on;
step S307: and sequentially cycling S304-S306 until the actual temperature reaches the preset target temperature.
In the temperature control process, the embodiment of the application acquires the real temperature T1 in the combustion chamber detected in real time; comparing the detected actual temperature T1 with a preset target temperature T0, and controlling the fan to be turned off when the actual temperature T1 is larger than or equal to the preset target temperature T0, namely, when cooling is needed.
In the case of the fan being turned off, i.e. no more oxygen is supplied, the burning moxa stick continues to burn, consuming the remaining oxygen in the combustion chamber, while the actual temperature T1 is still in an elevated state. With less and less oxygen in the moxa stick, the moxa stick burns to weaken and even has a tendency to extinguish, and the temperature rise can be slowly stopped. When the heat dissipation capacity and the heat supply capacity are monitored to be equal, the fan is controlled to be started, and the air flow pumped by the fan further takes away the heat in the combustion chamber, so that the actual temperature is reduced more quickly. And controlling the fan to stop rotating when the heat dissipation capacity and the heat supply capacity are equal again in the process that the actual temperature continuously drops but is not smaller than the preset target temperature.
Therefore, the invention realizes the rapid response to the temperature reduction process by detecting the actual temperature, and avoids the adverse effect caused by temperature regulation lag.
On the basis of any one of the above embodiments, a flowchart of a specific embodiment of monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion apparatus in real time in the temperature control method of the moxibustion apparatus provided by the present application is shown in fig. 4. The process may specifically include:
step S401: sequentially comparing the actual temperature at the current moment with the actual temperature at the previous moment;
step S402: judging the magnitude relation between the heat dissipation capacity and the heat supply capacity according to the change of the actual temperature at the current moment relative to the actual temperature at the previous moment; and when the absolute value of the difference value of the actual temperature at the current moment relative to the actual temperature at the previous moment is smaller than a preset threshold value, determining that the heat dissipation capacity is equal to the heat supply capacity.
According to the embodiment of the application, the purpose of judging the magnitude relation between the heat dissipation capacity and the heat supply capacity is achieved by monitoring the change of the actual temperature. When the absolute value of the difference between the actual temperature at the present time and the actual temperature at the previous time is smaller than the preset threshold value under the condition that the actual temperature of the moxibustion instrument is monitored at intervals of preset time, it can be determined that the heat dissipation capacity and the heat supply capacity are equal at the moment. The preset threshold may be set by a user, and is not limited herein.
On the basis of any one of the above embodiments, a flowchart of another specific embodiment of monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion apparatus in real time in the temperature control method of the moxibustion apparatus provided by the present application is shown in fig. 5. The process may specifically include:
s511: detecting the actual temperature at preset time intervals delta T, and recording the actual temperature at the current time T1 as T1, wherein the actual temperature after the preset time intervals delta T is T1';
s512: judging whether T1' is less than or equal to T1; if not, go to S513; if yes, go to S514;
s513: assigning the value of T1' to T1, and executing S511; if T1' is less than or equal to T1, determining that the heat dissipation capacity and the heat supply capacity are equal at the time T1; if T1' is greater than T1, returning to S511;
s514: assigning the value of T1' to T1, and executing S511; if T1' is larger than T1, determining that the heat dissipation capacity and the heat supply capacity are equal at the time T1; if T1' is less than or equal to T1, the process returns to S511.
According to the embodiment of the application, the actual temperature is detected at intervals of deltat preset time, for example, the actual temperature at the moment T1 is recorded as T1, the actual temperature at the moment T2 is recorded as T2, and the actual temperature at the moment T3 is recorded as T3; wherein, the intervals between t1 and t2, t2 and t3 are separated by the preset time interval delta t; when the three are judged to meet the relation of T1 < T2 > T3 or T1 > T2 < T3, the heat dissipation capacity and the heat supply capacity are equal at the time T2.
On the basis of any one of the above embodiments, a flowchart of still another specific embodiment of monitoring the magnitude relation between the heat dissipation capacity and the heat supply capacity of the moxibustion apparatus in real time in the temperature control method of the moxibustion apparatus provided by the present application is shown in fig. 6. The process may specifically include:
step S601: sequentially determining the temperature change rate of the actual temperature;
step S602: determining whether the actual temperature at the current moment reaches a temperature maximum inflection point or a temperature minimum inflection point according to the temperature change rate;
for example, the actual temperature at the first time is 48 ℃, the actual temperature at the previous time is 47.8 ℃, and the actual temperature at the next time is 47.9 ℃. It can be seen that the actual temperature rate of change is from +0.2 ℃/200ms to-0.1 ℃/200ms. The temperature change rate is changed from a positive value to a negative value, and it can be determined that the actual temperature at the current time reaches the inflection point of the maximum temperature. In this embodiment, the first time corresponds to the temperature maximum inflection point. Similarly, the temperature change rate is changed from a negative value to a positive value, and the fact that the actual temperature reaches the inflection point of the minimum temperature value at the current moment can be determined.
Step S603: judging the magnitude relation between the heat dissipating capacity and the heat supplying capacity based on the determined temperature maximum inflection point or temperature minimum inflection point; when the actual temperature at the current moment reaches the temperature maximum inflection point or the temperature minimum inflection point, the heat dissipation capacity and the heat supply capacity are determined to be equal.
Through the determination of the temperature maximum inflection point and the temperature minimum inflection point in step S602, when the actual temperature at the current moment reaches the temperature maximum inflection point or the temperature minimum inflection point, it is indicated that the actual temperature is no longer increased or decreased, i.e. the heat dissipation capacity is equal to the heat supply capacity.
