With reference to fig. 1-1 to 1-3, an embodiment of the present disclosure provides a sterilizer, which includes a liquid storage chamber 11, a depressurization chamber 12, a first pipeline 13, a second pipeline 14, a heating device 15, a pressurizing device 16, and a liquid pump 17. The disinfection liquid is stored in the liquid storage cavity 11. The pressure reduction cavity 12 is connected with the liquid storage cavity 11. One end of the first pipeline 13 is positioned below the liquid level of the liquid storage cavity 11, and the other end is positioned in the pressure reduction 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 the room through the pressure reduction cavity 12, and the pressure reduction cavity 12 is connected with the first pipeline 13. The heating device 15 is disposed in the pressure reducing chamber 12 (e.g., at the periphery of the pressure reducing chamber 12) and is used for heating the pressure reducing chamber 12 to vaporize the disinfecting liquid in the first pipeline 13. The pressurizing device 16 is connected with the liquid storage cavity 11, and the connection position is located above the liquid level, so that air is pumped into the liquid storage cavity 11 to drive the vaporized disinfectant to enter a 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 storage container 18 for disinfectant, and the liquid pump is used for pumping the disinfectant in the storage container 18 to the liquid storage cavity 11.
Optionally, the disinfection machine further comprises a first level sensor, a second level sensor and a concentration sensor. The first level sensor is disposed in the storage container 18 for detecting a level of the disinfectant in the storage container 18. The second liquid level sensor is arranged in the liquid storage cavity 11 and used for detecting the liquid level height of the disinfectant in the liquid storage cavity 11. The concentration sensor can be arranged in a room or a disinfection machine and used for detecting the concentration of the disinfection liquid in the room.
When the sterilizer is in operation, the liquid pump 17 pumps the sterilizing liquid from the storage container 18 to the storage chamber 11. The pressurizing device 16 pumps air into the reservoir chamber 11, and the pressure in the reservoir chamber 11 is higher than the pressure of the air in the room. Under the action of the air pressure, the air in the liquid storage cavity 11 flows to the room through the second pipeline 14, and high-speed air flow is formed. Because the first pipeline 13 and the second pipeline 14 are connected in the pressure reduction cavity 12, the first pipeline 13 in the pressure reduction cavity 12 forms negative pressure due to high-speed airflow, so that the disinfectant is driven to flow into the first pipeline 13 in the pressure reduction cavity 12 from the liquid storage cavity 11. Due to the low pressure of the first pipe 13 in the pressure reducing chamber 12, the boiling point of the sterilizing fluid is low. The temperature of the pressure reduction cavity 12 is increased by controlling the heating device 15, so that the disinfectant is vaporized. The vaporized disinfecting liquid is driven by the high-speed airflow of the second pipeline 14, and the brownian motion speed is increased, and the disinfecting liquid is diffused to the room through the second pipeline 14. The temperature of the disinfecting liquid is adjusted by the heating device 15, and the vaporization rate of the disinfecting liquid is changed. The flow rate of the sterilizing liquid is adjusted by the pressurizing device 16, so that the vaporization rate of the sterilizing liquid is changed.
The heating device 15 is a device for changing the heating temperature by adjusting the power, and may be, for example, an electric heating tube, a heating wire, a heating element, or the like. Since the object to be heated is a hydrogen peroxide disinfectant, the heating temperature is generally maintained at 90 to 150 ℃. The pressurizing device 16 is a device that changes the amount of air compressed per unit time by adjusting power, and may be, for example, an air pump such as an air pump or an inflator.
Referring to fig. 2, an embodiment of the present disclosure provides a method for controlling a sterilizing machine, including:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
And S250, controlling the power of the heating device by the disinfection machine according to the target vaporization rate and the current vaporization rate.
By adopting the method for controlling the disinfection machine provided by the embodiment of the disclosure, the liquid storage cavity is arranged inside the disinfection machine and is used for temporarily storing the hydrogen peroxide disinfectant extracted from the outside. The pressurizing device squeezes air into the liquid storage cavity, and compresses the air in the liquid storage cavity, so that high-speed airflow is formed in the second pipeline. The high-speed airflow enables the first pipeline in the pressure reduction cavity to form negative pressure, so that the hydrogen peroxide disinfectant is driven to flow into the first pipeline in the pressure reduction cavity from the liquid storage cavity. Because the boiling point of the hydrogen peroxide is low under the condition of low pressure, the temperature of the pressure reduction cavity is increased by controlling the heating device, and the vaporization of the hydrogen peroxide is realized. And obtaining the target vaporization rate and the current vaporization rate of the hydrogen peroxide disinfectant. And controlling the power of the heating device according to the current vaporization rate by taking the target vaporization rate as a control standard, and adjusting the temperature of the hydrogen peroxide disinfectant to change the vaporization rate of the disinfectant. The temperature of the hydrogen peroxide disinfectant is adjusted by controlling the power of the heating device, so that the vaporization rate is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
Referring to fig. 3, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
s231, the disinfection machine obtains the set room volume.
And S232, the disinfection machine obtains the set disinfection time.
And S233, the disinfection machine determines the target vaporization rate of the disinfection solution according to the set room volume and the set disinfection time.
And S241, detecting the current liquid level height of the disinfectant by the disinfector.
And S242, the disinfection machine obtains the initial liquid level height of the disinfection liquid.
And S243, determining the current consumption volume of the disinfectant by the disinfection machine according to the current liquid level height and the initial liquid level height.
And S244, detecting the current running time of the sterilizing machine.
And S245, determining the current vaporization rate of the disinfectant by the disinfection machine according to the current consumption volume and the current running time.
And S250, controlling the power of the heating device by the disinfection machine according to the target vaporization rate and the current vaporization rate.
With the method for controlling a disinfection machine provided by the embodiments of the present disclosure, a target vaporization rate of a disinfection liquid is determined according to a set room volume and a set disinfection time to determine a vaporization rate required when disinfection is completed at the set disinfection time. And determining the current consumption volume of the disinfectant according to the current liquid level height and the initial liquid level height so as to determine the actually consumed disinfectant after the operation of the disinfecting machine. The current vaporization rate is determined based on the consumed sterilizing fluid and the current operating time to obtain an actual vaporization rate of the sterilizing fluid during the current operating time. The accuracy of controlling the vaporization rate of the hydrogen peroxide disinfectant is improved by accurately obtaining the target vaporization rate and the current vaporization rate as the basis of controlling the power of the heating device.
Alternatively, the determination of the target vaporization rate of the disinfecting liquid by the disinfecting machine in step S233 according to the set room volume and the set disinfecting time includes: the disinfection machine determines the target consumption of the disinfection solution according to the set room volume and the target concentration. The sterilizer determines a ratio of the target consumption to the set sterilization time as a target vaporization rate of the sterilizing fluid. Wherein, the target concentration is the content (which can be expressed by percentage or density) of the expected disinfection solution in the room when the disinfection is finished, and the target concentration is fixedly stored in the disinfection machine in advance. Thus, the total amount of disinfectant to be consumed can be determined based on the set room volume and the target concentration. The ratio of the total amount to the set disinfection time is used as a target vaporization rate for reference, and the expected hydrogen peroxide consumption in unit time can be accurately calculated, so that the accuracy of controlling the vaporization rate of the hydrogen peroxide disinfectant 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 target concentration to be 60mg/m 3 . Then, the target consumption amount is 60mg and the target vaporization rate is 6 mg/min. The above numerical values are merely illustrative principles, and the actual numerical values need to be adjusted according to the requirements of precision, target concentration and the like.
Optionally, the step S243 determining the current consumption volume of the disinfecting liquid according to the current liquid level height and the initial liquid level height by the disinfecting machine includes: the sterilizer determines a difference in height between the initial liquid level height and the current liquid level height. And the current consumption volume of the disinfection machine is determined according to the height difference. In this way, since the shape of the storage container is a regular shape, the volume of the disinfectant solution to be reduced can be calculated by using a formula corresponding to the shape according to the height difference of the liquid level. By accurately calculating the actual consumption volume of the disinfectant, the current vaporization rate is determined more accurately, and the accuracy of controlling the vaporization rate of the hydrogen peroxide disinfectant is improved.
Optionally, the disinfection machine in step S245 determines a current vaporization rate of the disinfection liquid according to the current consumption volume and the current operation time, and determines a ratio of the current consumption volume to the current operation time as the current vaporization rate of the disinfection liquid for the disinfection machine. Therefore, the ratio of the volume consumed by the hydrogen peroxide to the current running time is used as the current vaporization rate, and the amount of the hydrogen peroxide actually consumed in unit time can be accurately calculated, so that the accuracy of controlling the vaporization rate of the hydrogen peroxide disinfectant is improved.
For example, for the calculation of the current vaporization rate, a hydrogen peroxide disinfectant solution having a concentration of 8% (density of about 1.03g/ml) was used, and 0.1ml of hydrogen peroxide disinfectant solution was consumed for one minute. Then, the current vaporization rate is 8.24 mg/min. The above numerical values are merely illustrative of the principle, and the actual numerical values need to be adjusted according to the accuracy, concentration, and the like.
Referring to fig. 4, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
S251, in case that the target vaporization rate is greater than the current vaporization rate, the sterilizing machine increases the current power of the heating device to be the target power, and performs the step S260.
S256, in case that the target vaporization rate is equal to the current vaporization rate, the sterilizing machine determines the current power of the heating means as the target power, and performs step S260.
And S261, in the case that the target vaporization rate is smaller than the current vaporization rate, the sterilizing machine reduces the current power of the heating device to be used as the target power.
S260, the sterilizing machine controls the heating device to operate at the target power, and returns to step S230.
With the method for controlling a disinfection machine provided by the embodiments of the present disclosure, when the target vaporization rate is greater than the current vaporization rate, the current vaporization rate is slow, so that the concentration of the disinfection liquid in the room is lower than expected. The current vaporization rate is increased by increasing the current power of the heating device to raise the temperature of the disinfecting liquid so as to enable the concentration of the disinfecting liquid to reach the requirement. When the target vaporization rate is equal to the current vaporization rate, the current vaporization rate reaches the target, which results in a desired concentration of the sterilant fluid in the room. By keeping the power of the heating device unchanged, the current vaporization rate is stabilized, so that the concentration of the disinfectant can meet the requirement. When the target vaporization rate is less than the current vaporization rate, the current vaporization rate is fast, which may cause the concentration of the sterilant fluid in the room to be higher than expected. The current vaporization rate is reduced by reducing the current power of the heating device to lower the temperature of the disinfectant so as to enable the concentration of the disinfectant to reach the requirement. The current vaporization rate of the disinfectant is changed by adjusting the power of the heating device, so that the vaporization rate is adjusted.
Referring to fig. 5, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
S252, in case that the target vaporization rate is greater than the current vaporization rate, the sterilizing machine determines the sum of the current power and the set power of the heating means as the target power, and performs step S260.
And S262, under the condition that the target vaporization rate is less than the current vaporization rate, determining the difference between the current power and the set power of the heating device as the target power by the disinfection machine.
S260, the sterilizing machine controls the heating device to operate at the target power, and returns to step S230.
With the method for controlling a sterilization machine provided by the embodiment of the present disclosure, when adjusting the power of the heating device, the current power is gradually adjusted each time with the set power as the adjustment amount. Because the sizes of the liquid storage cavity, the heating device, the first pipeline, the second pipeline and the like can be designed differently under different requirements, even if the heating device runs under the same power, the vaporization rates of the heating disinfectant are different. By gradually adjusting the current power with a fixed and unchangeable set power (such as 5W, 10W and the like), the current vaporization rate changes slowly, so that the target vaporization rate cannot be reached due to overshoot, and the accuracy of controlling the vaporization rate of the hydrogen peroxide disinfectant is improved.
Referring to fig. 6, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
And S253, under the condition that the target vaporization rate is greater than the current vaporization rate, the disinfection machine determines the rate difference value between the target vaporization rate and the current vaporization rate.
And S254, determining the adjusting power corresponding to the speed difference value according to the speed difference value by the disinfection machine.
S255, the sterilizing machine determines the sum of the current power and the adjusted power of the heating device as a target power, and performs step S260.
And S263, in case that the target vaporization rate is less than the current vaporization rate, the sterilizer determines a rate difference between the current vaporization rate and the target vaporization rate.
And S264, determining the adjusting power corresponding to the speed difference value by the disinfection machine according to the speed difference value.
And S265, determining the difference between the current power and the adjusted power of the heating device as the target power by the disinfection machine.
S260, the sterilizing machine controls the heating device to operate at the target power, and returns to step S230.
Wherein the larger the rate difference, the larger the adjustment power.
By adopting the method for controlling the sterilizing machine provided by the embodiment of the disclosure, when the power of the heating device is adjusted, the corresponding adjustment power is determined in a table look-up manner according to the difference (or the opposite number) between the target vaporization rate and the current vaporization rate. And under the condition of large speed difference, selecting large adjusting power to accelerate the current vaporization speed adjustment speed and save the adjustment time. In the case of small rate differences, a small adjustment power is selected to slow the speed of the current vaporization rate adjustment to prevent overshoot. The current power is adjusted according to different speed difference values, so that the speed adjustment is accelerated, and the overshoot is prevented at the same time, thereby improving the accuracy of the vaporization rate control of the hydrogen peroxide disinfectant.
Because the sizes of the liquid storage cavity, the heating device, the first pipeline, the second pipeline and the like can be designed differently under different requirements, the corresponding relation between the adjustment power and the speed difference value can be obtained through calculation or experiments according to the actual size. For example, when the rate difference is less than 10% of the target vaporization rate, the adjusted power is 10W. When the rate difference is greater than or equal to 10% and less than 30% of the target vaporization rate, the adjusted power is 30W. When the difference in rate is greater than or equal to 30% of the target vaporization rate, the adjusted power is 50W.
Referring to fig. 7, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
s210, the disinfection machine receives the set room volume and the set disinfection time input by the user.
S211, the disinfection machine determines the target liquid level height according to the set room volume and the set disinfection time.
S212, the disinfection machine detects the initial liquid level height of the disinfection liquid in the storage container.
S213, under the condition that the initial liquid level height is less than the target liquid level height, the disinfection machine reminds the user to replenish the disinfectant, and the step S212 is returned.
And S214, controlling the liquid pump of the liquid pump to operate at the first initial power by the disinfector under the condition that the initial liquid level height is greater than or equal to the target liquid level height.
S215, the sterilizing machine controls the pressurizing device to operate at the second initial power.
S216, the sterilizing machine controls the heating device to operate at a third initial power.
And S220, detecting the current concentration of the disinfectant in the room by the disinfector.
And S221, stopping the operation of the sterilizing machine under the condition that the current concentration is greater than or equal to the target concentration, and finishing the sterilization.
And S230, under the condition that the current concentration is less than the target concentration, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
And S250, controlling the power of the heating device by the disinfection machine according to the target vaporization rate and the current vaporization rate, and returning to the step S220.
By adopting the method for controlling the disinfection machine provided by the embodiment of the disclosure, initialization is carried out after power-on, and the set room volume and the set disinfection time input by a user are received to determine the target vaporization rate. Before the operation of the disinfection machine is started, the initial liquid level height of the disinfection liquid in the storage container is detected through the first liquid level sensor so as to determine the total amount of the disinfection liquid. When the initial liquid level is lower than the target liquid level, the total amount of the disinfectant is insufficient and needs to be supplemented. The user is reminded to supplement the disinfectant in time so as to enable the concentration of the hydrogen peroxide in the room to meet the requirement when the set disinfection time is reached. And when the device is initialized, the liquid pump, the pressurizing device and the heating device are controlled to operate at respective initial powers, and the device is ready for disinfection. The concentration of the disinfectant in the room is detected by a concentration sensor. When the current concentration is greater than or equal to the target concentration, the concentration of the disinfectant in the room exceeds or meets the requirement, the disinfectant is continuously vaporized to cause the concentration of the disinfectant to be too high to corrode articles, and the operation of the disinfection machine is stopped. The disinfection liquid is reminded when the disinfection liquid is insufficient in the initialization process, and the operation is stopped when the current concentration is too high, so that the vaporization of the disinfection liquid meets the requirement.
Referring to fig. 8, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
And S250, controlling the power of the heating device by the disinfection machine according to the target vaporization rate and the current vaporization rate.
And S270, controlling the power of the pressurizing device by the sterilizing machine according to the target vaporization rate and the current vaporization rate.
By adopting the method for controlling the disinfection machine provided by the embodiment of the disclosure, the power of the pressurizing device can change the pressure in the liquid storage cavity, so that the vaporization rate of the disinfection liquid is influenced. If only the heating device is adjusted without adjusting the power of the heating device, 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 speed in the second pipeline. The current vaporization rate is adjusted by matching the pressurizing device with the heating device, the decomposition efficiency of the disinfectant is improved, and the limitation 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 vaporization rate is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
Optionally, the sterilization machine in step S270 controls the power of the pressurizing means according to the target vaporization rate and the current vaporization rate, including: the sterilizer determines a rate difference between the current vaporization rate and the target vaporization rate. And the sterilizing machine determines the pressurizing power of the pressurizing device through proportional-integral-derivative operation according to the speed difference. The sterilizer controls the pressurizing device to operate at a pressurizing power. In this way, by determining the pressurizing power of the pressurizing device by the proportional-integral-derivative operation with the rate difference as the form of the deviation, it is possible to achieve a reduction in the overshoot while quickly adjusting the current vaporization rate. The power of the pressurizing device is adjusted to adjust the flowing speed of the hydrogen peroxide disinfectant, so that the vaporization rate is adjusted in the process of vaporizing the hydrogen peroxide disinfectant.
Referring to fig. 9, another method for controlling a sterilizer according to an embodiment of the present disclosure includes:
and S230, the disinfection machine obtains the target vaporization rate of the disinfection solution.
And S240, the disinfection machine obtains the current vaporization rate of the disinfection liquid.
And S250, controlling the power of the heating device by the disinfection machine according to the target vaporization rate and the current vaporization rate.
S280, the sterilizer detects the temporary storage liquid level height of the disinfectant in the liquid storage cavity.
And S290, controlling the power of the liquid pump by the disinfection machine according to the temporary storage liquid level height.
By adopting the method for controlling the disinfection machine provided by the embodiment of the disclosure, the content of the disinfection liquid in the liquid storage cavity can be changed due to the change of the vaporization rate in the operation process of the liquid pump. The temporary storage liquid level height of the disinfectant in the liquid storage cavity is detected through the second liquid level sensor. The power of the liquid pump is adjusted according to the height of the temporary storage liquid level, so that too much or too little disinfectant in the liquid storage cavity is prevented, and the vaporization rate of the disinfectant is prevented from being influenced.
Optionally, the method for controlling the power of the liquid pump according to the temporary liquid level in the disinfection machine in step S290 includes: and under the condition that the temporary storage liquid level height is less than the first set height, the power of the liquid pump is increased by the disinfection machine. And under the condition that the temporary storage liquid level height is greater than the second set height, the disinfection machine reduces the power of the liquid pump. And under the condition that the temporary storage liquid level height is greater than or equal to the first set height and less than or equal to the second set height, the power of the liquid pump is kept unchanged by the disinfection machine. The first set height is larger than the vertical distance between one end of the liquid storage cavity and the joint of the liquid pump and the liquid storage cavity, the second set height is smaller than the vertical distance between the joint of the pressurizing device and the liquid storage cavity and the joint of the liquid pump and the liquid storage cavity, and the first set height is smaller than the second set height. Like this, when the liquid level height of keeping in was less than first when setting for the height, the height of the antiseptic solution in the stock solution chamber probably was less than the bottom of first pipeline, leads to the unable antiseptic solution of absorbing of first pipeline. The power of the liquid pump is increased to supplement the disinfectant, so that the vaporization rate is prevented from being influenced by the shortage of the disinfectant. When the height of the temporary storage liquid level is larger than the second set height, the height of the disinfectant in the liquid storage cavity is possibly higher than a connecting port of the pressurizing device and the liquid storage cavity, and the disinfectant flows into the pressurizing device or the second pipeline, so that air flow cannot be realized. The power of the liquid pump is reduced to reduce the disinfectant, so that the vaporization rate is prevented from being influenced by too much disinfectant. When the height of the temporary storage liquid level is greater than or equal to the first set height and less than or equal to the second set height, the vaporization rate is not influenced by the moderate height of the disinfectant, and the power of the liquid pump is kept unchanged. The power of the liquid pump is adjusted under different conditions, so that the vaporization rate of the disinfectant is prevented from being influenced.
