Without further limitation, the use of the phrase "including a. -. said." does not exclude the presence of other elements of interest in a circuit or device comprising the element (e.g., steps in a method or elements in a device, such as a part of a processor, part of a program or software, etc.).
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.
Fig. 1A is a schematic diagram of a control circuit according to an embodiment of the present disclosure, and as shown in fig. 1A, the control circuit includes: the device comprises a power supply module 10, a current sampling module 11, a boosting module 12, a load 13 and a controller 14; the input end of the boosting module 12 is connected with the power supply module 10, the output end of the boosting module 12 is connected with the load 13, the current sampling module 11 is used for collecting the current value between the power supply module 10 and the boosting module 12, and the control end of the current sampling module 11 is connected with the controller 14; the controller 14 is configured to drive the boosting module 12 to start working after receiving the sterilization function instruction; the controller 14 is configured to obtain a sampled current value of the current sampling module 11, and disconnect the boost module 12 from the power supply module 10 when the sampled current value is determined to be greater than a preset current value.
In the embodiment of the application, the control circuit is applied to the sterilization equipment, and the sterilization equipment is used for executing corresponding sterilization operation after receiving the sterilization function instruction; here, the sterilization operation refers to an autoclaving operation; here, the high voltage means a high voltage, for example, 10000V, 20000V, or the like.
For example, the sterilization function instruction may be an instruction to turn on the sterilization function; the instruction may be sent to the sterilization apparatus by the user through a remote controller, or may be sent in other manners, which is not limited in this application.
In the embodiment of the application, after a controller in a control circuit receives an instruction sent by a user for starting a sterilization function, the controller drives a boosting module to start working; here, the controller may be a Microcontroller Unit (MCU), or other control devices for implementing circuit control functions.
For example, the boosting module may represent a power supply module that boosts a supply voltage of the power supply module to a set high voltage; the input end of the boosting module is connected with the power supply module, namely, the power supply module can provide input voltage for the boosting module; thus, after the boosting module starts to work, the power supply voltage of the power supply module can be boosted to the set high voltage.
For example, the output end of the boost module is connected to the load, so that after the boost module boosts the supply voltage of the power supply module to a set high voltage, the set high voltage can be used as the supply voltage of the load for driving the load to work.
Here, the power supply voltage of the power supply module and the setting of the high voltage may be set according to actual conditions, which is not limited in the embodiment of the present application. For example, the power supply voltage of the power supply module may be 12V, and the set high voltage may be 10000V.
In the embodiment of the application, in the working process of the boosting module, the current acquisition module acquires a current value between the power supply module and the boosting module and sends a sampled current value obtained by sampling to the controller; here, the current collecting module may collect the current value in real time, or may collect the current value at set time intervals.
Illustratively, after acquiring a sampling current value sent by a current acquisition module, a controller compares the sampling current value with a preset current value to obtain a comparison result; if the sampling current value is determined to be larger than the preset current value through the comparison result, the fact that a discharging phenomenon exists between the boosting module and the load is indicated; at this time, the connection between the boosting module and the power supply module is cut off, so that the discharge phenomenon can be eliminated, and the safety of the control circuit can be ensured.
On the contrary, if the sampling current value is determined to be smaller than or equal to the preset current value through the comparison result, the boosting module and the load are in a normal working state; namely, no discharging phenomenon exists between the boosting module and the load; at this time, the above-described cutting operation need not be performed.
Illustratively, the preset current value is a current value preset in the controller in advance, and is used for representing whether the working state between the boosting module and the load is abnormal or not; here, the value of the preset current value may be set according to an actual situation, and this is not limited in the embodiment of the present application.
Exemplarily, the controller is further configured to determine whether the sampled current value is zero or not before determining that the sampled current value is greater than the preset current value, so as to obtain a determination result; if the controller determines that the sampling current value is zero according to the judgment result, the controller reports abnormal information of the disconnection state between the boosting module and the load to the terminal equipment of the user; here, the terminal device may be a user's mobile phone, a personal computer, or the like.
In the embodiment of the application, after the controller acquires the sampling current value sent by the current acquisition module, firstly, whether the sampling current value is zero or not is judged, if the sampling current value is zero, it is indicated that the current control circuit is likely to have abnormality, and at the moment, the controller reports abnormal information of a disconnected state between the boost module and the load to a terminal device of a user for reminding the user of maintaining the circuit; otherwise, if the sampled current value is not zero, it is continuously determined whether the sampled current value is greater than the preset current value, and the specific implementation manner is described in the above embodiments and will not be described herein again.
Here, the manner of reminding the abnormal information by the terminal device is not limited, and for example, the abnormal information may be notified by a voice method or a text display method.
For example, after the terminal device of the user receives the above-mentioned abnormal information, it indicates that there is a high possibility of abnormality in the current control circuit, at this time, the user may perform inspection and maintenance on the current control circuit according to the abnormal information, and may continue to send a corresponding sterilization function instruction to the controller in the sterilization device when it is determined that there is no abnormality in the current control circuit after the inspection and maintenance.
It can be seen that in the embodiment of the application, when the sampling current value of the current sampling module is determined to be zero through the controller in the sterilization equipment, the user can be timely reminded to maintain the sterilization equipment by sending abnormal information to the user, and the occurrence probability of potential safety hazards is reduced to a certain extent.

Exemplarily, after the MCU receives the sterilization function command, the voltage boosting module is driven to start to operate, and then the power supply voltage of the power supply module is boosted to a set high voltage.
Step 22: and judging whether the sampling current value is zero or not.
Illustratively, in the working process of the boosting module, the current collection module collects a sampling current value between the power supply module and the boosting module and sends the collected sampling current value to the controller, and at the moment, the controller judges whether the sampling current value is zero or not. If zero, go to step 20; otherwise, if not, step 23 is executed.
