Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a disinfection and sterilization method, a disinfection and sterilization device, an air conditioner and a readable storage medium. Background Art

[0002] Nowadays, disinfection and sterilization devices are used more and more frequently. Common disinfection and sterilization devices on the market use the photocatalysis of titanium dioxide to achieve the purpose of disinfection and sterilization, generally using ultraviolet lamps to catalyze titanium dioxide.

[0003] To achieve efficient photocatalytic utilization of titanium dioxide, ultraviolet lamps are usually installed in the catalytic module. However, ultraviolet lamps with longer wavelengths produce less ozone, but have little effect on the catalytic module, which is not conducive to the catalytic module stimulating reactive oxygen species. Therefore, to achieve efficient photocatalytic utilization of titanium dioxide, it is preferred to install ultraviolet lamps with shorter wavelengths, such as 185-nanometer ultraviolet lamps, in the catalytic module. Although ultraviolet lamps with this wavelength are beneficial for the catalytic module to stimulate reactive oxygen species, they also emit ozone when in use. When the amount of ozone generated indoors is too high, it will cause harm to indoor residents. When disinfection and sterilization devices are turned on today, ozone is controlled through ventilation, which cannot achieve accurate control of the amount of ozone.

[0004] It should be noted that the above content is only used to assist in understanding the technical problem solved by the present invention, and does not mean that the above content is admitted as prior art. Summary of the Invention

[0005] The main purpose of the present invention is to provide a disinfection and sterilization method, a disinfection and sterilization device, an air conditioner and a readable storage medium, aiming to achieve the purpose of improving the universality of the air conditioner.

[0006] To achieve the above object, the present invention provides a disinfection and sterilization method, which is applied to a disinfection and sterilization device, wherein the disinfection and sterilization device includes a first ultraviolet lamp and a second ultraviolet lamp, wherein the wavelength of light emitted by the first ultraviolet lamp is greater than the wavelength of light emitted by the second ultraviolet lamp, and the disinfection and sterilization method includes the following steps:

[0007] After the disinfection and sterilization device is started, the first ultraviolet lamp is started;

[0008] Obtaining the ozone concentration in the room where the disinfection and sterilization device is located;

[0009] When the ozone concentration is less than or equal to a first preset threshold, the second ultraviolet lamp is started.

[0010] Optionally, after the step of starting the second ultraviolet lamp, the method further includes:

[0011] When the ozone concentration is greater than the first preset threshold, the second ultraviolet lamp is turned off.

[0012] Optionally, while executing the step of turning off the second ultraviolet lamp, the following steps are also executed:

[0013] Start the de-ozonation device.

[0014] Optionally, after the step of obtaining the ozone concentration in the room where the disinfection and sterilization device is located, the method further includes:

[0015] When the ozone concentration is greater than a second preset threshold, the deozonation device is started, wherein the second preset threshold is greater than the first preset threshold.

[0016] Optionally, before the step of starting the first ultraviolet lamp, the disinfection and sterilization method further includes:

[0017] After the disinfection and sterilization device is started, the humidity value in the room where the disinfection and sterilization device is located is obtained;

[0018] When the humidity value is less than a preset humidity threshold, the humidifier is controlled to start humidification.

[0019] Optionally, the step of controlling the humidifier to start humidification includes:

[0020] Obtaining the relative humidity and current temperature value of the room;

[0021] Determine, based on the relative humidity and the current temperature, a target temperature value corresponding to when the humidity value reaches the preset humidity value;

[0022] The refrigeration component is controlled to operate according to the target temperature value.

[0023] Optionally, the step of controlling the refrigeration component to operate according to the target temperature value includes:

[0024] Determining a target operating time according to the current temperature value and the target temperature value;

[0025] After the refrigeration component runs for the target running time, the step of turning on the first ultraviolet lamp is performed.

[0026] The present application also provides a disinfection and sterilization device, which includes a memory, a processor, and a disinfection and sterilization program stored in the memory and executable on the processor. When the disinfection and sterilization program is executed by the processor, the steps of the disinfection and sterilization method described above are implemented.

[0027] The present application also provides an air conditioner, which includes a sterilization device, a memory, a processor, and a sterilization program stored in the memory and runnable on the processor. The sterilization device is connected to the processor, and when the sterilization program is executed by the processor, the steps of the sterilization method described above are implemented.

[0028] In addition, the present application also provides a readable storage medium, which stores a disinfection and sterilization program. When the disinfection and sterilization program is executed by a processor, the various steps of the disinfection and sterilization method described above are implemented.

[0029] The disinfection and sterilization method, disinfection and sterilization device and readable storage medium provided by the present invention are independently controlled by setting a first ultraviolet lamp and a second ultraviolet lamp. After the disinfection and sterilization device is started, the first ultraviolet lamp is first used to act on the catalytic module. If it is detected that the ozone concentration in the room is low, the second ultraviolet lamp is started to improve the photocatalytic efficiency of the catalytic module and improve the disinfection and sterilization effect. Since no ozone is generated when the first ultraviolet lamp is turned on, it can be avoided that the indoor ozone level is too high during the disinfection and sterilization process and affects the health of the user. At the same time, the second ultraviolet lamp is started when the ozone concentration is low. Although the second ultraviolet lamp generates ozone, it does not affect the health of the user because the ozone concentration is at a safe value, and a small amount of ozone is also beneficial to improving the catalytic efficiency of the catalytic module. Therefore, the catalytic control process of this embodiment achieves safer and more effective disinfection and sterilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The common disinfection and sterilization devices on the market use the photocatalysis of titanium dioxide to achieve the purpose of disinfection and sterilization, and generally use ultraviolet lamps to catalyze titanium dioxide.

[0039] Because UV lamps with longer wavelengths produce less ozone, but have less effect on the catalytic module, it is not conducive to the catalytic module stimulating reactive oxygen species, while UV lamps with shorter wavelengths are conducive to the catalytic module stimulating reactive oxygen species. Therefore, in order to achieve efficient utilization of titanium dioxide photocatalytic process, it is preferred to install UV lamps with shorter wavelengths, such as 185-nanometer UV lamps, in the catalytic module. However, 185-nanometer UV lamps also emit ozone when in use. When the amount of ozone generated indoors is too high, it will cause harm to indoor residents. When the disinfection and sterilization device is turned on, ozone is controlled by ventilation, which cannot achieve accurate control of the ozone amount.

[0040] Based on this, an embodiment of the present invention provides a disinfection and sterilization method, by installing two ultraviolet lamps in a catalytic module, one ultraviolet lamp does not produce ozone, or produces less ozone, and the other ultraviolet lamp can help the catalytic module to stimulate active factors. The two ultraviolet lamps are controlled independently, and then the states of the two ultraviolet lamps are controlled separately in combination with the environmental requirements during the disinfection and sterilization process, so as to achieve good disinfection and sterilization effects while ensuring that the ozone concentration in the room is low, thereby achieving safe and efficient disinfection and sterilization effects.

[0041] To better understand the above technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] As an implementation method, the hardware environment architecture involved in the disinfection and sterilization method can be as follows: Figure 1 shown.

[0043] Specifically, the hardware architecture involved in the disinfection and sterilization method may include a device, such as a mobile terminal, or a control terminal for controlling a disinfection and sterilization device or an air conditioner, or a disinfection and sterilization device having a processor.

[0044] As an implementation, the terminal or air conditioner includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. The communication bus 103 is used to connect and communicate with these components. The processor 102 is used to call an application to perform a disinfection operation.

[0045] The memory 102 may be a high-speed RAM memory or a non-volatile memory, such as a disk memory.

[0046] It can be understood that, in one embodiment, the disinfection and sterilization program for implementing the disinfection and sterilization process of the air conditioner is stored in the memory 102 of the terminal or air conditioner. When the processor 101 calls the disinfection and sterilization program from the memory 102, it executes the adjustment process of the following embodiments.

[0047] After the disinfection and sterilization device is started, the first ultraviolet lamp is started;

[0048] Obtaining the ozone concentration in the room where the disinfection and sterilization device is located;

[0049] When the ozone concentration is less than or equal to a first preset threshold, the second ultraviolet lamp is started.

[0050] In another embodiment, the disinfection and sterilization program for implementing the air conditioner can also be stored in a computer-readable storage medium. When the storage medium is applied to a computer, the processor 101 of the computer can call the disinfection and sterilization program from the storage medium to execute the above process.

[0051] Based on the hardware architecture of the above air conditioner, the following embodiments of the present invention are proposed.

[0052] As in the first embodiment:

[0053] Please refer to Figure 2 , the adjustment method proposed in this embodiment includes:

[0054] Step S10, after the disinfection and sterilization device is started, the first ultraviolet lamp is started;

[0055] Step S20, obtaining the ozone concentration in the room where the disinfection and sterilization device is located;

[0056] Step S30, determining whether the ozone concentration is less than or equal to a first preset threshold;

[0057] If yes, step S40 is executed to start the second ultraviolet lamp.

[0058] If not, step S50 is executed to keep the second ultraviolet lamp in the off state.

[0059] The execution terminal in this embodiment is a disinfection and sterilization device or a terminal used to control the disinfection and sterilization of the disinfection and sterilization device. Optionally, the disinfection and sterilization device can be a standalone disinfection and sterilization device or a disinfection and sterilization device installed in an air conditioner. This embodiment uses the disinfection and sterilization device installed in an air conditioner to illustrate the specific implementation process of this application.

[0060] Please refer to Figure 3 The air conditioner includes a catalytic module 10, which is provided with a photocatalyst material, a first ultraviolet lamp 20 and a second ultraviolet lamp 30. The first ultraviolet lamp 20 is a 254-nanometer ultraviolet lamp, and the second ultraviolet lamp 30 is a 185-nanometer ultraviolet lamp. In this way, the wavelength of light emitted by the first ultraviolet lamp 20 is greater than the wavelength of light emitted by the second ultraviolet lamp 30.

[0061] Optionally, the first ultraviolet lamp 20 is connected to a first driving power supply 40, and the second ultraviolet lamp 30 is connected to a second driving power supply 50. The first driving power supply 40 and the second driving power supply 50 are respectively connected to the air conditioner control circuit 60. The control circuit 60 is connected to an ozone sensor 70, which is used to detect the ozone concentration in the room and transmit the detected ozone concentration to the control circuit 60.

[0062] After the air conditioner's disinfection and sterilization device is activated, the first UV lamp 20 is first activated. The first UV lamp 20 acts on the catalytic module 10, causing the catalytic module 10 to excite reactive oxygen species and disinfect the room. The ozone concentration in the room is then monitored in real time or periodically. When the ozone concentration is high (e.g., greater than the first preset threshold), only the first UV lamp 20 is activated. At this time, the first UV lamp 20 is used to excite the catalytic module 10. Since the first UV lamp 20 does not generate ozone, in an environment with high ozone concentration, disinfection and sterilization can proceed normally while preventing further increase in ozone concentration.

[0063] When the ozone concentration is low (such as less than or equal to the first preset threshold), in order to facilitate the catalytic module 10 to excite the active oxygen factor and improve the activation efficiency, the second ultraviolet lamp 30 can be started at this time, and the second ultraviolet lamp 30 is used to act on the catalytic module 10. After the second ultraviolet lamp 30 is started, it can generate a certain amount of ozone. A small amount of ozone makes the excitation efficiency of the catalytic module 10 higher, thereby improving the activation efficiency of the catalytic module 10.

[0064] Alternatively, after the air conditioner's disinfection and sterilization device is activated, the indoor ozone concentration is first detected. If the indoor ozone concentration is detected to be high (e.g., greater than the first preset threshold), only the first ultraviolet lamp 20 is activated, and the second ultraviolet lamp 30 is kept inactive. If the ozone concentration is low (e.g., less than or equal to the first preset threshold), both the first and second ultraviolet lamps 20 and 30 are activated.

[0065] Optionally, the first preset threshold is a safe ozone concentration value, that is, when the indoor ozone concentration is below the first preset threshold, the ozone concentration is harmless to the human body, the indoor environment is relatively safe, and the ozone concentration can be increased by a certain amount without being harmful to the human body, so the second UV lamp can be activated. When the ozone concentration is higher than the first preset threshold, the indoor ozone concentration is high. If ozone continues to be generated at this time, the ozone concentration will easily exceed the safe range. At this time, it is necessary to control the disinfection and sterilization device to stop generating ozone, that is, to stop activating the second UV lamp.

[0066] Optionally, the first preset threshold may be 30 ppb.

[0067] This embodiment organically combines indoor ozone concentration detection with the efficient use of titanium dioxide for photocatalysis. This not only controls indoor ozone within a safe range, but also utilizes ozone-generating UV lamps to provide ozone for more efficient titanium dioxide photocatalysis. This embodiment eliminates the need to consider exceeding indoor ozone concentrations when presetting disinfection times, allowing disinfection to continue for a longer period within a safe range, more effectively meeting disinfection needs.

[0068] The first UV lamp is driven by a first driving power supply, and the second UV lamp is driven by a second driving power supply, thereby independently driving the first UV lamp and the second UV lamp. Thus, during the disinfection process, the first UV lamp or the second UV lamp can be independently activated by controlling the first driving power supply and the second driving power supply respectively.

[0069] Based on this, in this embodiment, by setting the first ultraviolet lamp and the second ultraviolet lamp to be independently controlled, after the disinfection and sterilization device is started, the first ultraviolet lamp is first used to act on the catalytic module. If it is detected that the ozone concentration in the room is low, the second ultraviolet lamp is started to improve the photocatalytic efficiency of the catalytic module and improve the disinfection and sterilization effect. Since no ozone is generated when the first ultraviolet lamp is turned on, it can avoid excessive indoor ozone during the disinfection and sterilization process and affect the health of the user. At the same time, the second ultraviolet lamp is started when the ozone concentration is low. Although the second ultraviolet lamp generates ozone, it does not affect the health of the user because the ozone concentration is at a safe value, and a small amount of ozone is also beneficial to improving the catalytic efficiency of the catalytic module. Therefore, the catalytic control process of this embodiment achieves safer and more effective disinfection and sterilization.

[0070] Second embodiment:

[0071] Based on the above examples, please refer to Figure 4 Optionally, after the disinfection and sterilization device is started, if it is detected that the ozone concentration is greater than the first preset threshold, step S60 may be further performed: determining whether the ozone concentration is greater than a second preset threshold;

[0072] If so, step S70 is executed to start the deozonation device, wherein the second preset threshold is greater than the first preset threshold.

[0073] If not, step S50 is executed to keep the second ultraviolet lamp in the off state.

[0074] Among them, the second preset threshold is the upper limit of the ozone concentration safety range, that is, when the indoor ozone concentration exceeds the second preset threshold, the room is not suitable for people to stay and will have an impact on human health.

[0075] Optionally, the second preset threshold is 50 ppb. When the indoor ozone concentration is higher than 50 ppb, the ozone concentration has exceeded a safe concentration range. In this embodiment, the ozone removal module is activated to help reduce the indoor ozone concentration.

[0076] After detecting that the ozone concentration is greater than the first preset value, this embodiment continues to detect whether the ozone concentration is greater than the second preset threshold. If it is greater, it means that the indoor ozone concentration is high. At this time, the indoor ozone needs to be treated to reduce the indoor ozone concentration.

[0077] The air conditioner in this embodiment is also provided with an ozone removal device (see Figure 3 ), the deozonation device 80 includes an adsorption material and at least one fan. When the fan is started, the adsorption of ozone by the adsorption material can be accelerated, thereby reducing the ozone concentration in the room.

[0078] If the indoor ozone concentration is not high, the second ultraviolet lamp 30 can be kept in the off state, and only the first ultraviolet lamp 20 is used to act on the catalytic module 10 to achieve the purpose of disinfection and sterilization.

[0079] Alternatively, in some embodiments, during the disinfection and sterilization process, when the ozone concentration is greater than the first preset threshold, in order to reduce the indoor ozone concentration to below the first preset threshold, so as to turn on the second ultraviolet lamp to improve the catalytic efficiency of the catalytic module, the deozonizer can be directly started to reduce the indoor temperature to below the first preset threshold.

[0080] The addition of an ozone removal device can also reduce the indoor ozone concentration to a safe range when the indoor ozone exceeds the standard due to the external environment, thereby protecting the safety of indoor occupants.

[0081] Third embodiment:

[0082] This embodiment is based on the first embodiment mentioned above, please refer to Figure 5 Optionally, after step S10, continue to detect the indoor ozone concentration. Step S80, when the ozone concentration is greater than the first preset threshold, turn off the second ultraviolet lamp.

[0083] Since the second UV lamp generates ozone when activated, to prevent the generated ozone from causing the indoor ozone concentration to exceed a safe value, after the second UV lamp is activated to catalyze the catalytic module, the indoor ozone level must be monitored in real time or periodically. If the indoor ozone concentration exceeds the first preset threshold, the second UV lamp is turned off, and only the first UV lamp is used to catalyze the catalytic module.

[0084] Optionally, in some embodiments, while executing step S80, the following steps are also executed:

[0085] Step S90: start the deozonation device.

[0086] Optionally, the air conditioner in this embodiment is also provided with an ozone removal device (see Figure 3 ), the deozonation device includes an adsorption material and at least one fan. When the fan is started, the adsorption of ozone by the adsorption material can be accelerated, thereby reducing the ozone concentration in the room.

[0087] If the second ultraviolet lamp is turned on and produces more ozone, the ozone device can be started to assist in reducing the ozone concentration in the room, so as to ensure that the indoor ozone concentration always remains within the safety threshold.

[0088] Optionally, in some embodiments, when the ozone concentration is greater than the first preset threshold, the deozonizer may be activated first. After the deozonizer is activated, the indoor ozone concentration is continuously detected, and the ozone concentrations detected at different time points are compared to determine the trend of the ozone concentration. If the ozone concentration is decreasing, it indicates that the deozonizer is effective, and the second UV lamp may be kept activated to enable efficient catalysis by the catalytic module. If the ozone concentration is still increasing, it indicates that the deozonizer's ozone removal rate is lower than the ozone increase rate, and ozone production must be stopped and the second UV lamp turned off.

[0089] This embodiment achieves more refined ozone control, which allows ozone to be controlled within a safe range while improving the disinfection and sterilization effect of the catalytic module.

[0090] Fourth embodiment:

[0091] This embodiment is based on all the above embodiments. Optionally, please refer to Figure 6Before step S10, the disinfection and sterilization method further includes:

[0092] Step S100, after the disinfection and sterilization device is started, the humidity value in the room where the disinfection and sterilization device is located is obtained;

[0093] Step S110, determining whether the humidity value is less than a preset humidity threshold;

[0094] When the humidity value is less than the preset humidity threshold, S120 , the humidifier is controlled to start humidification.

[0095] When the humidity value is greater than or equal to the preset humidity threshold, the first ultraviolet lamp is directly controlled to turn on.

[0096] This embodiment is based on the fact that ozone's sterilizing effect is very sensitive to humidity. When the humidity is too low, ozone's sterilizing effect on the air and surfaces will be limited. When the humidity is above a certain value (the preset humidity threshold), the ozone diffused in the air will effectively sterilize the air and surfaces.

[0097] Therefore, in this embodiment, before controlling the first ultraviolet lamp to turn on, the humidity value in the room is first detected. If the humidity value is higher than the preset humidity threshold, the first ultraviolet lamp can be directly controlled to turn on to perform the disinfection operation.

[0098] If the humidity value is lower than the preset humidity threshold, in order to improve the disinfection effect, the refrigeration component is first controlled to reduce the indoor humidity.

[0099] It is understood that the first humidity threshold can be 70% relative humidity, that is, when the indoor humidity is higher than 70%, the ozone diffused in the air will effectively disinfect the air and the surface of objects. Before the disinfection function is activated, the humidity of the air is measured. When the humidity is lower than 70%, the indoor humidity is adjusted by the humidification component to achieve a more disinfecting state.

[0100] Optionally, the humidifier can be an independent humidifier or a refrigeration component of an air conditioner (which increases the relative humidity in the room by cooling and cooling). If the humidifier is an independent humidifier, the humidifier is directly controlled to start humidification. If the humidifier is a refrigeration component of an air conditioner, the refrigeration component is controlled to start a cooling mode.

[0101] Optionally, when the air conditioner is equipped with the disinfection and sterilization device, the refrigeration component can be directly activated for cooling. If the disinfection and sterilization device is an independent device, it can be set to connect with various household appliances based on the Internet of Things. When the indoor humidity is low, a control instruction is sent to the humidifier or air conditioner to trigger the humidifier to start humidification, or the air conditioner to start cooling.

[0102] Optionally, the air conditioner of the execution terminal of this embodiment, that is, the air conditioner includes the disinfection and sterilization device and a refrigeration component. In this embodiment, the method of starting humidification includes starting the refrigeration component to run a cooling mode.

[0103] Optionally, the control of the refrigeration component operating in a refrigeration mode includes:

[0104] Obtaining the relative humidity and current temperature value of the room;

[0105] Determine, based on the relative humidity and the current temperature, a target temperature value corresponding to when the humidity value reaches the preset humidity value;

[0106] The refrigeration component is controlled to operate according to the target temperature value.

[0107] In order to quickly reach the humidity required for disinfection and sterilization in the room, this embodiment directly determines the target temperature value through the current indoor temperature value, relative humidity value and the preset humidity value; the air conditioner operates according to the target temperature value, so that the indoor humidity required for disinfection and sterilization can be quickly reached.

[0108] It will be appreciated that this embodiment calculates the enthalpy-humidity relationship between temperature and humidity. For example, when the indoor temperature is 30 degrees Celsius and the indoor humidity is 40%, based on the relationship between indoor temperature and relative humidity, the indoor relative humidity can be increased to 70% by lowering the indoor temperature to 20 degrees Celsius.

[0109] Optionally, in this embodiment, the first ultraviolet lamp can be started after the humidifier is started for a preset time. After starting the first ultraviolet lamp, the humidifier continues to operate, so that the indoor humidity gradually decreases and the disinfection effect of the disinfection and sterilization device gradually improves.

[0110] Alternatively, in some embodiments, the humidification time can be calculated by the target temperature value and the current temperature value, and after the humidifier starts the humidification time, the first ultraviolet lamp is started to start the disinfection.

[0111] For example, the operating time required for the indoor temperature to reach the target temperature is calculated using the current operating parameters of the refrigeration component, the target temperature value, and the current temperature value. The operating time is the humidification time.

[0112] Alternatively, after adjusting the operating parameters of the refrigeration component based on the target temperature value, the operating time required for the indoor temperature to reach the target temperature value is calculated based on the adjusted operating parameters, the current temperature value and the target temperature value, and the operating time is used as the humidification time.

[0113] In this embodiment, disinfection is started after the humidity reaches a preset humidity value, so that the disinfection and sterilization device can always be in a better environment to perform disinfection work.

[0114] Alternatively, in other embodiments, after starting the humidifier, the first ultraviolet lamp can be started at the same time, and the humidifier continues to run. After the humidifier runs for the target running time and the ozone concentration in the room is lower than the first preset threshold, the second ultraviolet lamp is started. The ozone generated by the second ultraviolet lamp, combined with the indoor environmental humidity, maximizes the disinfection effect of the ozone.

[0115] That is, in this embodiment, before starting the second ultraviolet lamp, the indoor humidity only needs to reach the preset humidity value. The first ultraviolet lamp disinfection and the humidifier humidification are carried out simultaneously, reducing the disinfection waiting time.

[0116] The present application also provides a disinfection and sterilization device, which includes a memory, a processor, and a disinfection and sterilization program stored in the memory and executable on the processor. When the disinfection and sterilization program is executed by the processor, the steps of the disinfection and sterilization method described above are implemented.

[0117] The present application also provides an air conditioner, which includes a sterilization device, a memory, a processor, and a sterilization program stored in the memory and runnable on the processor. The sterilization device is connected to the processor, and when the sterilization program is executed by the processor, the steps of the sterilization method described above are implemented.

[0118] In addition, the present application also provides a readable storage medium, which stores a disinfection and sterilization program. When the disinfection and sterilization program is executed by a processor, the various steps of the disinfection and sterilization method described above are implemented.

[0119] Optionally, an embodiment of the present invention further provides a computer program product, which includes a disinfection and sterilization program code, and when the disinfection and sterilization program code is executed by a processor, various embodiments of the above-mentioned adjustment are implemented.

[0120] It should be noted that the above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
