Referring to fig. 1-1 to 1-3, an embodiment of the present disclosure provides a sterilizer including a liquid storage chamber 11, a depressurization chamber 12, a first pipe 13, a second pipe 14, a heating device 15, a pressurizing device 16, and a liquid pump 17. The liquid storage cavity 11 stores disinfectant. The depressurization chamber 12 is connected with the liquid storage chamber 11. One end of the first pipeline 13 is positioned below the liquid level of the liquid storage cavity 11, and the other end of the first pipeline is positioned in the depressurization cavity 12. One end of the second pipeline 14 is positioned above the liquid level of the liquid storage cavity 11, the other end of the second pipeline is communicated with a room through the depressurization cavity 12, and the depressurization cavity 12 is connected with the first pipeline 13. The heating device 15 is disposed in the pressure reducing chamber 12 (for example, a periphery of the pressure reducing chamber 12) and is used for heating the pressure reducing chamber 12 to vaporize the disinfectant in the first pipeline 13. The pressurizing device 16 is connected with the liquid storage cavity 11, and the connecting part is positioned above the liquid level and is used for driving air into the liquid storage cavity 11 to drive vaporized disinfectant to enter the room through the second pipeline 14. One end of the liquid pump 17 is connected with the liquid storage cavity 11, and the other end is connected with an external disinfectant storage container 18, and is used for pumping the disinfectant in the storage container 18 to the liquid storage cavity 11.
Optionally, the sterilizer further comprises a first liquid level sensor, a second liquid level sensor, and a concentration sensor. The first liquid level sensor is disposed in the storage container 18 and is used for detecting the liquid level of the disinfectant in the storage container 18. The second liquid level sensor is arranged in the liquid storage cavity 11 and is used for detecting the liquid level height of the disinfectant in the liquid storage cavity 11. The concentration sensor can be arranged between rooms or in a sterilizer and is used for detecting the concentration of the disinfectant in the rooms.
In operation of the sterilizer, the liquid pump 17 pumps sterilizing liquid from the storage container 18 to the liquid storage chamber 11. The pressurizing means 16 pumps air into the liquid storage chamber 11, the pressure in the liquid storage chamber 11 being higher than the pressure of the air in the room. Under the action of air pressure, air in the liquid storage cavity 11 flows into the room through the second pipeline 14 to form high-speed air flow. Because the first pipeline 13 and the second pipeline 14 are connected in the pressure reducing cavity 12, the high-speed air flow can enable the first pipeline 13 in the pressure reducing cavity 12 to form negative pressure, so that disinfectant is driven to flow into the first pipeline 13 in the pressure reducing cavity 12 from the liquid storage cavity 11. Due to the low pressure in the first line 13 in the pressure reducing chamber 12, the boiling point of the sterilizing liquid is low. The temperature of the depressurization chamber 12 is increased by controlling the heating device 15 to vaporize the sterilizing liquid. The vaporized sterilizing fluid is driven by the high-speed air flow of the second pipe 14, and the Brownian motion speed is increased and is diffused into the room through the second pipe 14. The temperature of the sterilizing liquid is adjusted by the heating device 15 to change the vaporization rate of the sterilizing liquid. The flow rate of the sterilizing fluid is adjusted by the pressurizing means 16 to change the vaporization rate of the sterilizing fluid.
The heating device 15 is a device for changing a heating temperature by adjusting power, and may be, for example, an electrothermal tube, an electrothermal wire, a heating element, or the like. Because the object to be heated is hydrogen peroxide disinfectant, the heating temperature is generally maintained at 90-150 ℃. The pressurizing device 16 is a device for changing the air compression amount per unit time by adjusting the power, and may be, for example, an air pump such as an inflation pump or an inflator pump.
In connection with the sterilizer illustrated in fig. 1-1 through 1-3, embodiments of the present disclosure provide a method for controlling a sterilizer. As shown in fig. 2, the method includes:
s230, the sterilizer detects the current concentration of the disinfectant.
S240, the sterilizer obtains the target concentration of the disinfectant.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration.
By adopting the method for controlling the sterilizer provided by the embodiment of the disclosure, the sterilizer is internally provided with the liquid storage cavity for temporarily storing the hydrogen peroxide disinfectant extracted from the outside. The pressurizing device drives air into the liquid storage cavity to compress the air in the liquid storage cavity, so that high-speed air flow is formed in the second pipeline. The high-speed air flow enables the first pipeline in the pressure reducing cavity to form negative pressure, so that the hydrogen peroxide disinfectant is driven to flow into the first pipeline in the pressure reducing cavity from the liquid storage cavity. Due to the fact that the boiling point of hydrogen peroxide is low under the condition of low pressure, the temperature of the depressurization cavity is increased by controlling the heating device, and vaporization of the hydrogen peroxide is achieved. The current concentration of the hydrogen peroxide sterilizing liquid in the room is detected by a concentration sensor, and the target concentration of the hydrogen peroxide sterilizing liquid is obtained. The target concentration is used as a control standard, the power of the heating device is controlled according to the current concentration, and the vaporization rate of the hydrogen peroxide disinfectant is adjusted so as to change the current concentration. The vaporization rate of the disinfectant is adjusted by controlling the power of the heating device, so that the concentration of the disinfectant is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
As shown in connection with fig. 3, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s230, the sterilizer detects the current concentration of the disinfectant.
S241, the sterilizer obtains the target vaporization rate of the disinfectant.
S242, detecting the current running time by the sterilizer.
S243, the sterilizer determines the target concentration of the sterilizing liquid according to the target vaporization rate and the current running time.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration.
By adopting the method for controlling the sterilizer provided by the embodiment of the disclosure, the target vaporization rate of the hydrogen peroxide sterilizing liquid is determined according to the needs of a user. The current run time is detected and the concentration at which the disinfectant in the room is expected to reach is determined. The target concentration of the disinfectant under the current running time is determined and is used as a control standard, and the power of the heating device is adjusted according to the current concentration to enable the current concentration to reach the target concentration, so that the adjustment of the concentration of the disinfectant is realized.
Optionally, the sterilizer in step S241 obtains a target vaporization rate of the sterilizing fluid, including: the sterilizer obtains a set room volume. The sterilizer obtains a set sterilization time. The sterilizer determines a target vaporization rate of the sterilizing fluid according to the set room volume and the set sterilization time. Thus, a target vaporization rate of the sterilizing fluid is determined based on the set room volume and the set sterilization time to determine a desired vaporization rate at the completion of sterilization at the set sterilization time. And determining the target concentration through the accurately obtained target vaporization rate, and taking the target concentration as a basis for controlling the power of the heating device so as to improve the accuracy of adjusting the concentration of the disinfectant.
Optionally, the sterilizer determines a target vaporization rate of the sterilizing fluid according to a set room volume and a set sterilization time, including: the sterilizer determines the final consumption of the sterilizing fluid according to the volume and the final concentration of the set room. The sterilizer determines a ratio of the final consumption to the set sterilization time as a target vaporization rate of the sterilizing liquid. Wherein the final concentration is the content (which can be expressed as a percentage or a density) of the sterilizing liquid expected in the room when the sterilization is completed, and the sterilizing liquid is fixedly stored in the sterilizer in advance. Thus, the total amount of disinfectant to be consumed can be determined based on the set room volume and the final concentration. The ratio of the total amount to the set disinfection time is used as a target vaporization rate for reference, and the expected consumed hydrogen peroxide amount in unit time can be accurately calculated, so that the accuracy of the concentration adjustment of the disinfection solution is improved.
For example, for calculation of the target vaporization rate, the room volume is set to 1m 3 Setting the disinfection time to be 10min and the final concentration to be 60mg/m 3 . Then the final consumption was 60mg and the target vaporization rate was 6mg/min. The above values are merely illustrative of the principles and actual values need to be adjusted according to the accuracy and final concentration requirements.
Optionally, the sterilizing machine in step S243 determines the target concentration of the sterilizing liquid according to the target vaporization rate and the current operation time, including: the sterilizer determines the product of the target vaporization rate and the current run time as a target consumption of sterilizing fluid. The sterilizer determines a quotient of the target consumption and the set room volume as a target concentration of the sterilizing liquid. Thus, the expected concentration of the disinfectant in the room can be accurately calculated according to the target vaporization rate, the current running time and the set room volume, so that the power of the heating device is controlled, and the adjustment of the concentration of the disinfectant is realized.
For example, the target vaporization rate is 6mg/min, the current running time is 2min, and the room volume is set to 1m 3 . Then, the target concentration is 12mg/m 3 。
Optionally, the sterilizer in step S250 controls the power of the heating device according to the current concentration and the target concentration, including: in the case that the current concentration is not equal to the target concentration, the sterilizer controls the power of the heating device according to the concentration difference between the current concentration and the target concentration. In case the current concentration is equal to the target concentration, the sterilizer controls the power of the heating device according to the vaporization rate of the sterilizing liquid. In this way, when the current concentration is not equal to the target concentration, the power of the heating device is controlled with priority being given to the current concentration reaching the target concentration. At this time, the current vaporization rate and the target vaporization rate are not equal, thereby changing the current concentration. In the case where the current concentration is equal to the target concentration, the current vaporization rate is brought to the target vaporization rate, thereby maintaining the current concentration at the target concentration. The current concentration is stabilized at the target concentration by preferentially adjusting the concentration to reach equilibrium and secondarily adjusting the vaporization rate to reach equilibrium at the concentration equilibrium.
As shown in connection with fig. 4, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s230, the sterilizer detects the current concentration of the disinfectant.
S240, the sterilizer obtains the target concentration of the disinfectant.
S251, in the case where the current density is not equal to the target density, the sterilizer determines a density difference between the current density and the target density.
S252, the sterilizer determines the adjusting power corresponding to the concentration difference according to the concentration difference.
S253, the sterilizer determines the sum of the current power and the adjustment power of the heating device as the first target power.
S254, the sterilizer controls the heating apparatus to operate at the first target power, and returns to step S230.
S255, in the case that the current concentration is equal to the target concentration, the sterilizer obtains the current vaporization rate of the sterilizing liquid.
S256, the sterilizer controls the power of the heating device according to the current vaporization rate and the target vaporization rate, and returns to the step S230.
By adopting the method for controlling the sterilizer provided by the embodiment of the disclosure, under the condition that the current concentration is not equal to the target concentration, the first target power of the heating device takes the concentration difference value as the control basis, so that the current concentration reaches the target concentration. And under the condition that the current concentration is equal to the target concentration, the second target power of the heating device is controlled by taking the current vaporization rate and the target vaporization rate as the basis, so that the current vaporization rate reaches the target vaporization rate. The current concentration is stabilized at the target concentration by preferentially adjusting the concentration to reach equilibrium and secondarily adjusting the vaporization rate to reach equilibrium at the concentration equilibrium.
The current density being equal to the target density means equal within an allowable error range, and not exactly equal.
Because the sizes of the liquid storage cavity, the heating device, the first pipeline, the second pipeline and the like are designed differently under different demands, the corresponding relation between the adjustment power and the concentration difference can be obtained through calculation or experiment according to the actual size. For example, in the case where the detection interval time (interval time between adjacent two controls) is 1min, when the concentration difference is greater than 0 and less than 10% of the target concentration, the power is adjusted to-10W. When the concentration difference is greater than or equal to 10% and less than 30% of the target concentration, the power is adjusted to-30W. When the concentration difference is greater than or equal to 30% of the target concentration, the power is adjusted to-50W. When the concentration difference is less than 0 and greater than-10% of the target concentration, the power is adjusted to 10W. When the concentration difference is less than or equal to-10% of the target concentration and greater than-30% of the target concentration, the power is adjusted to 30W. When the concentration difference is less than or equal to-30% of the target concentration, the power is adjusted to 50W. The above values are merely illustrative, and the actual values need to be adjusted according to the detection interval time, the model of the heating device, and the like.
Optionally, the sterilizer in step S255 obtains a current vaporization rate of the sterilizing fluid, including: the sterilizer obtains the volume difference of the sterilizing liquid in the liquid storage cavity. The sterilizer obtains a current consumed volume of sterilizing fluid in the storage vessel. The sterilizer determines a current vaporization rate of the sterilizing liquid according to the volume difference and the current consumed volume. In this way, during the vaporization of the hydrogen peroxide disinfectant, the disinfectant in the liquid storage cavity is consumed on one hand and is replenished by the liquid pump on the other hand. There is a volume difference between consumption of sterilizing fluid and imbalance in replenishment. The volume of disinfectant replenished to the reservoir is determined by the current volume consumed in the reservoir (reservoir replenishment). The difference between the consumption and replenishment of the sterilizing fluid is determined by the difference in volume of the sterilizing fluid in the fluid reservoir. The current vaporization rate of the disinfectant can be determined according to the volume difference and the current consumption volume, so that the accuracy of the vaporization rate control of the hydrogen peroxide disinfectant is improved.
Optionally, the sterilizer obtains a volume difference of the sterilizing fluid in the fluid storage chamber, including: the sterilizer obtains the current volume of sterilizing fluid in the fluid storage chamber. The sterilizer obtains the previous volume of sterilizing liquid in the liquid storage cavity. The sterilizer determines the difference between the current volume and the previous volume as a volume difference. Therefore, the shape of the liquid storage cavity is a regular shape, and the current volume of the disinfectant can be calculated according to the liquid level height detected by the second liquid level sensor. And the consumption of the disinfectant in the liquid storage cavity and the supplementing difference are determined by calculating the volume difference, so that the current vaporization rate of the disinfectant is determined, and the accuracy of rate control is improved.
Optionally, the sterilizer obtains a current consumption volume of sterilizing fluid in the storage vessel, comprising: the sterilizer obtains a current level of sterilizing fluid in the storage vessel. The sterilizer obtains a previous level of sterilizing fluid in the storage container. The sterilizer determines a height difference between the current liquid level and the previous liquid level. The sterilizer determines the current consumption volume according to the height difference. Thus, since the shape of the storage container is a regular shape, the volume of the sterilizing liquid can be calculated by using the formula corresponding to the shape according to the height difference of the liquid level. The volume of the disinfectant is accurately calculated, the current vaporization rate is more accurately determined, and the accuracy of hydrogen peroxide disinfectant vaporization rate control is improved.
Optionally, the sterilizer in step S256 controls the power of the heating device according to the current vaporization rate and the target vaporization rate, including: the sterilizer determines a rate differential between the current vaporization rate and the target vaporization rate. The sterilizer determines a second target power of the heating apparatus based on the rate difference. The sterilizer controls the heating apparatus to operate at a second target power. In this way, when the current concentration is equal to the target concentration, the second target power of the heating device is controlled by the speed difference value, so that the current vaporization rate reaches the target vaporization rate. The power of the heating device is controlled by taking the speed difference value as the control basis, so that the accuracy of controlling the vaporization speed of the hydrogen peroxide disinfectant is improved.
Optionally, the sterilizer determines the second target power of the heating device according to the rate difference, and determines the second target power of the heating device according to the rate difference through proportional-integral-derivative operation. Thus, by determining the second target power of the heating device by proportional-integral-derivative operation in the form of a difference in rate, it is possible to achieve rapid adjustment of the current vaporization rate while reducing the overshoot. The power of the heating device is adjusted to adjust the flowing speed of the hydrogen peroxide disinfectant so as to realize the adjustment of the vaporization rate to reach balance in the process of vaporizing the hydrogen peroxide disinfectant.
As shown in connection with fig. 5, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s230, the sterilizer detects the current concentration of the disinfectant.
S240, the sterilizer obtains the target concentration of the disinfectant.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration.
S260, the sterilizer controls the power of the pressurizing device according to the current concentration and the target concentration.
By adopting the method for controlling the sterilizing machine provided by the embodiment of the disclosure, the pressure in the liquid storage cavity can be changed due to the power of the pressurizing device, so that the vaporization rate of the sterilizing liquid is influenced. If the heating device is only adjusted, but the power of the pressurizing device is not adjusted, when the heating temperature of the heating device reaches a certain value, the current vaporization rate will not change due to the limitation of the gas flow rate in the second pipeline. The pressurizing device and the heating device are matched to adjust the current vaporization rate, so that the decomposition efficiency of the disinfectant is improved, and the limit of air pressure on the current vaporization rate is eliminated. The power of the pressurizing device is adjusted to adjust the flowing speed of the hydrogen peroxide disinfectant, so that the concentration of the disinfectant is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
Optionally, the sterilizer in step S260 controls the power of the pressurizing device according to the current concentration and the target concentration, including: in the case where the current concentration is not equal to the target concentration, the sterilizer determines a third target power of the pressurizing device through a proportional-integral-derivative operation according to the concentration difference. In the case where the current concentration is equal to the target concentration, the sterilizer determines a third target power of the pressurizing means through a proportional-integral-derivative operation according to the rate difference. The sterilizer controls the pressurizing device to operate at a third target power. In this way, by determining the third target power of the pressurizing means by means of a proportional-integral-derivative operation in the form of a concentration difference or a rate difference as a deviation in different cases, it is possible to achieve a rapid adjustment of the current vaporization rate while reducing the overshoot. The power of the pressurizing device is adjusted to adjust the flowing speed of the hydrogen peroxide disinfectant, so that the concentration of the disinfectant is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
As shown in connection with fig. 6, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s230, the sterilizer detects the current concentration of the disinfectant.
S240, the sterilizer obtains the target concentration of the disinfectant.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration.
S270, the sterilizer obtains the current vaporization rate of the sterilizing fluid.
S280, the sterilizer obtains the rated vaporization rate of the disinfectant.
S290, when the duration time that the current vaporization rate is larger than the rated vaporization rate reaches the set time, the sterilizer sends out an alarm prompt.
With the method for controlling a sterilizer provided by the embodiment of the present disclosure, a rated vaporization rate (maximum vaporization rate multiplied by a safety factor, for example, 0.9) is determined according to the model of the sterilizer. In the process of adjusting the vaporization rate, the current vaporization rate is always larger than the rated vaporization rate in the set time, which indicates that the current concentration can not always reach the target concentration due to the condition that air circulation exists in the room. If the operation is continued under the condition, not only the waste of the disinfectant and the loss of the sterilizer are caused, but also the service life of devices in the sterilizer is reduced when the sterilizer is operated under the power higher than the rated vaporization rate. The alarm reminding is sent out when the air in the room circulates, so that a user is informed that the air in the room needs to be sealed, and the disinfection effect of the disinfection machine and the service life of the disinfection machine are improved.
The set time refers to a preset time value, and may be, for example, 3min, 5min or 7min.
As shown in connection with fig. 7, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s200, the sterilizer receives the set room volume input by the user.
S280, the sterilizer obtains the rated vaporization rate of the disinfectant.
S201, the sterilizer determines the minimum sterilization time according to the set room volume and the rated vaporization rate.
S202, the sterilizer obtains the minimum vaporization rate of the disinfectant.
S203, the sterilizer determines the maximum sterilization time according to the set room volume and the minimum vaporization rate.
S204, the sterilizer receives the set sterilization time input by the user.
S205, when the set disinfection time is smaller than the minimum disinfection time or larger than the maximum disinfection time, the disinfection machine sends out an error prompt, and returns to the step S204.
S230, detecting the current concentration of the disinfectant by the sterilizer under the condition that the set disinfection time is greater than or equal to the minimum disinfection time and less than or equal to the maximum disinfection time.
S240, the sterilizer obtains the target concentration of the disinfectant.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration.
With the method for controlling the sterilizer provided by the embodiment of the present disclosure, the sterilizer has a minimum vaporization rate (without considering shutdown) and a rated vaporization rate in the process of vaporizing the hydrogen peroxide sterilizing liquid. For example, the heating temperature is 90 to 150 ℃ when the heating device is vaporizing. The vaporization rate corresponding to 90 ℃ is the minimum vaporization rate, the vaporization rate corresponding to 150 ℃ is the maximum vaporization rate, and the product of the maximum vaporization rate and the safety factor is determined as the rated vaporization rate. Within the set room volume, there is a maximum disinfection time and a minimum disinfection time corresponding to the minimum vaporization rate and the nominal vaporization rate. When the set disinfection time input by the user is smaller than the minimum disinfection time, the disinfection machine cannot complete disinfection within the time, and an error prompt is sent out to inform the user that the set disinfection time needs to be increased. When the set disinfection time input by the user is greater than the maximum disinfection time, the disinfection opportunity finishes disinfection in advance, so that the loss and the idle time of the disinfection machine are increased, and an error prompt is sent to inform the user that the set disinfection time needs to be reduced. When the input of the set disinfection time does not meet the requirement, the user is reminded to realize the disinfection in the room.
As shown in connection with fig. 8, an embodiment of the present disclosure provides another method for controlling a sterilizer, comprising:
s200, the sterilizer receives the set room volume input by the user.
S204, the sterilizer receives the set sterilization time input by the user.
S210, the sterilizer determines the target liquid level height according to the set room volume and the set sterilization time.
S211, detecting the initial liquid level of the disinfectant in the storage container by the sterilizer.
S212, under the condition that the initial liquid level is smaller than the target liquid level, the sterilizer reminds a user to supplement the sterilizing liquid, and returns to the step S211.
S220, controlling the liquid pump to operate at the first initial power by the sterilizer under the condition that the initial liquid level height is greater than or equal to the target liquid level height.
S221, the sterilizer controls the pressurizing device to operate at a second initial power.
S222, controlling the heating device to operate at a third initial power by the sterilizer.
S242, detecting the current running time by the sterilizer.
S230, in the case that the current running time is smaller than the set disinfection time, the disinfection machine detects the current concentration of the disinfection solution and executes step S240.
S231, stopping the operation of the sterilizer when the current operation time is greater than or equal to the set sterilization time, and ending the sterilization.
S240, the sterilizer obtains the target concentration of the disinfectant.
S250, the sterilizer controls the power of the heating device according to the current concentration and the target concentration, and returns to the step S242.
By adopting the method for controlling the sterilizer provided by the embodiment of the disclosure, the sterilizer is initialized after being electrified, and the set room volume and the set sterilization time input by a user are received. Before the sterilizer starts to operate, the initial liquid level of the sterilizing liquid in the storage container is detected by the first liquid level sensor to determine the total amount of the sterilizing liquid. When the initial liquid level is smaller than the target liquid level, the total amount of the disinfectant is insufficient and needs to be supplemented. The user is reminded to timely supplement the sterilizing liquid, so that the concentration of hydrogen peroxide in the room reaches the requirement when the set sterilizing time is reached. During initialization, the liquid pump, the pressurizing device and the heating device are controlled to operate at the respective initial powers, so that disinfection preparation is performed. In case the current running time is less than or equal to the set disinfection time, the disinfection is not completed yet and needs to be continued. If the current operation time is longer than the set disinfection time, the disinfection is completed, and the continuous vaporization of the disinfection solution can cause the concentration of the disinfection solution to be too high to corrode articles, so that the disinfection machine stops operating. The disinfection solution is stopped when the running time reaches the set disinfection time by reminding when the disinfection solution is insufficient in the initialization process, so that the vaporization of the disinfection solution reaches the requirement.
