Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method and a control device for a fan, and a computer-readable storage medium. Background Art

[0002] At present, the comfortable wind mode of fans such as circulating fans cannot meet the user's need to use the comfortable wind mode to intelligently adjust the fan gear changes to provide the most comfortable wind experience under different user body conditions. Since the user's body surface temperature varies in different states, as the comfortable wind mode is activated to supply air, the user's body surface temperature gradually decreases as the comfortable wind supply time increases. The continuous wind blowing from the fan in the comfortable wind gear may cause the user to feel uncomfortable, so it cannot meet the wind feeling needs of users with different body characteristics. Summary of the invention

[0003] In view of this, the present invention provides a method for controlling a fan to solve the technical problem in the prior art that the fan cannot be intelligently adjusted according to the user's status information and the environment in which it is located.

[0004] In a first aspect, the present invention provides a method for controlling a fan, wherein the fan is provided with an infrared thermal imaging detector, and the control method comprises: receiving a user's request to start the fan; obtaining the user's body surface temperature information T, the distance information between the fan and the user, and the ambient temperature information of the user; based on the body surface temperature information T, the distance information, and the ambient temperature information, controlling the fan to start and operate according to a preset gear.

[0005] Beneficial effect: The fan control method of the present invention realizes the different needs of users for air supply modes in multiple states and multiple environmental states, and through intelligent adjustment and control of the fan, it can accurately match the actual needs of users, thereby improving the user experience and meeting the user's personalized needs.

[0006] Specifically, the circulation fan is equipped with an infrared thermal imaging detector to detect the ambient temperature, air supply distance, and changes in the user's body temperature in real time, and intelligently adjust the comfortable air supply level to ensure that the user can experience the most comfortable wind feeling in real time;

[0007] The fan has 5 comfortable wind speed settings, which are divided into low speed, medium speed and high speed according to the speed. Gears 1 and 2 are defined as low speed; gear 3 is defined as medium speed; gears 4 and 5 are defined as high speed. Under the experimental environment of 25℃ and the air supply distance of 2m from people, the most comfortable wind speed of the current model is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is equipped with an infrared thermal imaging detector, which scans the fan's air supply area at the same time, obtains and detects the ambient temperature, air supply distance and human body temperature, and intelligently determines and adjusts the execution of the comfortable wind supply gear, truly meeting the user's wind sensation needs at different body temperature states.

[0008] In an optional embodiment, based on the body surface temperature information T, distance information and ambient temperature information, controlling the fan to start and operate at a preset gear specifically includes: based on the body surface temperature information T in the range of 36.5°C to 37.5°C, determining that the user is in a normal state, and controlling the fan to operate at a medium speed gear; based on the body surface temperature information T>37.5°C, determining that the user is in a state after strenuous exercise, and controlling the fan to increase the medium speed gear by 1 gear, and operate at the first increased gear.

[0009] Beneficial effects: The rise in body temperature after exercise can be determined by the following embodiments: the rise in body temperature after exercise is usually systemic, but may be more obvious in certain parts (such as the face and limbs); the user's thermal imaging image may show a uniform temperature rise throughout the body or in specific parts; the specific value of the body temperature after exercise can be used to compare with a preset threshold to determine whether the user is in a state of body temperature rise after exercise; the user's movements can also be recognized by the camera, such as high-intensity activities such as running and brisk walking, to determine whether the user is in a state of exercise, thereby inferring that he needs to dissipate heat quickly.

[0010] In an optional implementation, the control method further includes: monitoring body surface temperature information T in real time;

[0011] Based on the body surface temperature information T decreasing by less than 0.3°C and the body surface temperature information T>37.5°C, the fan is controlled to increase by one gear on the basis of the first increase gear, until the highest gear.

[0012] Beneficial effect: By controlling the fan to increase one gear on the basis of the first increase gear, until the highest gear, the purpose of quickly dissipating heat for the user can be achieved, thereby controlling the user's body temperature within a comfortable temperature range and improving the user's experience.

[0013] In an optional embodiment, the control method further includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by ≥0.3°C and the body surface temperature information T>37.5°C, controlling the fan to maintain operation at the first increase gear.

[0014] Beneficial effect: By controlling the fan to maintain the first increase gear, the purpose of stable heat dissipation for the user can be achieved, thereby controlling the user's body temperature within a comfortable temperature range, reducing the physical discomfort caused by the rapid drop in the user's body temperature, for example, reducing the user's cold caused by the rapid drop in the user's body temperature, and improving the user's experience.

[0015] In an optional embodiment, the control method also includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by less than 0.3°C, and the body surface temperature information T is in the range of 36.5°C to 37.5°C, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at a medium speed gear.

[0016] Beneficial effect: When the body surface temperature information T is in the range of 36.5℃~37.5℃, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at the medium speed gear, which blows more comfortable wind to the user.

[0017] In an optional embodiment, the control method also includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by ≥0.3°C, and the body surface temperature information T is in the range of 36.5°C to 37.5°C, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at a medium speed gear.

[0018] Beneficial effect: When the body surface temperature information T is in the range of 36.5℃~37.5℃, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at the medium speed gear, which blows more comfortable wind to the user.

[0019] In an optional implementation, the control method further includes: real-time monitoring of body surface temperature information T; and controlling the fan to stop working if the body surface temperature information T drops by ≥0.3°C and the body surface temperature information T is lower than 36.5°C.

[0020] Beneficial effect: If the body surface temperature information T is lower than 36.5°C, it means that the user does not need to cool down at this time. By controlling the fan to stop working, the user's body temperature can be further reduced, which can reduce the user's physical discomfort.

[0021] In an optional embodiment, the control method further includes: controlling the fan to operate at a low speed if the fan has not detected a user for a first consecutive preset time; controlling the fan to stop if the fan has not detected a user for a second consecutive preset time, wherein the second preset time is greater than the first preset time.

[0022] Beneficial effect: When the infrared imaging detector detects no human body for 5 consecutive minutes, the current comfort wind gear is directly reduced to low speed gear 1, and it is determined that the user has left the air supply area at this time. In order to save energy, the comfort wind low speed gear 1 is intelligently executed;

[0023] When the infrared imaging detector is set to continuously detect time > Y min and there is no user in the air supply area, the gear will immediately shut down and stop working. It will continuously detect that there is no user in the air supply area for Y min. The user can set the Y min time setting on the fan App.

[0024] In an optional implementation, the control method further includes: recalculating the second preset time based on detecting body surface temperature information T for a third preset time in a row after the fan fails to detect the user.

[0025] Beneficial effect: When the infrared imaging detector continuously detects that there is no user in the air supply area, if the user's body temperature is detected for 10 consecutive seconds, the Y min automatic shutdown time for continuous detection without user will be reset.

[0026] In an optional embodiment, the ambient temperature information defaults to 25°C, and the control method further includes: for every 5°C increase in the ambient temperature information, the fan increases by 1 gear on the current gear; for every 5°C decrease in the ambient temperature information, the fan decreases by 1 gear on the current gear.

[0027] Beneficial effects: The fan is used in an ambient temperature range of (3°C, 40°C). The current model is operated in an experimental environment of 25°C. The most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is installed with an infrared thermal imaging detector to monitor changes in the user's body temperature in real time, and intelligently adjust the comfortable wind supply gear. The comfortable wind gear is compensated and adjusted by detecting the ambient temperature, ensuring that the user can feel the most comfortable wind experience under different body conditions.

[0028] In an optional implementation, the distance information defaults to 2m, and the control method further includes: for every 1m increase in the distance information, the fan increases by 1 gear on the current gear; for every 1m decrease in the distance information, the fan decreases by 1 gear on the current gear.

[0029] Beneficial effect: The fan uses an air supply distance range (0m, 3m), and the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is installed with an infrared thermal imaging detector to monitor the distance information in real time and intelligently adjust the comfortable wind supply gear. The comfortable wind gear is compensated and adjusted by detecting the air supply distance to ensure that the distance information can feel the most comfortable wind experience under different conditions.

[0030] In a second aspect, the present invention also provides a fan control device, including: a receiving module for receiving a user's request to start the fan; an acquisition module for acquiring the user's body surface temperature information, the distance information between the fan and the user, and the user's ambient temperature information; a control module for controlling the fan to start and work according to a preset gear based on the body surface temperature information T, the distance information, and the ambient temperature information.

[0031] In a third aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the fan control method of the first aspect of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Combine the following Figures 1 to 3 , describing embodiments of the present invention.

[0041] like Figure 1 and Figure 2As shown, according to an embodiment of the present invention, on the one hand, the present invention provides a method for controlling a fan, the fan is provided with an infrared thermal imaging detector, and the control method includes: receiving a user's request to start the fan; obtaining the user's body surface temperature information T, the distance information between the fan and the user, and the user's ambient temperature information; based on the body surface temperature information T, the distance information, and the ambient temperature information, controlling the fan to start and work according to a preset gear.

[0042] In the above embodiments, the fan control method of the embodiment of the present application realizes the user's different needs for air supply modes in multiple states and multiple environmental states, and through intelligent adjustment and control of the fan, it can accurately match the user's actual needs, thereby improving the user's usage experience and meeting the user's personalized needs.

[0043] Specifically, the circulation fan is equipped with an infrared thermal imaging detector to detect the ambient temperature, air supply distance, and changes in the user's body temperature in real time, and intelligently adjust the comfortable air supply level to ensure that the user can experience the most comfortable wind feeling in real time;

[0044] The fan has 5 comfortable wind speed settings, which are divided into low speed, medium speed and high speed according to the speed. Gears 1 and 2 are defined as low speed; gear 3 is defined as medium speed; gears 4 and 5 are defined as high speed. Under the experimental environment of 25℃ and the air supply distance of 2m from people, the most comfortable wind speed of the current model is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is equipped with an infrared thermal imaging detector, which scans the fan's air supply area at the same time, obtains and detects the ambient temperature, air supply distance and human body temperature, and intelligently determines and adjusts the execution of the comfortable wind supply gear, truly meeting the user's wind sensation needs at different body temperature states.

[0045] Furthermore, the human body sensing sensor can detect whether there is someone in the room. When someone enters the room, the fan can automatically adjust the air supply direction and wind speed according to the pre-set mode; the human body thermal imaging sensor and camera can detect the user's status, and the fan can automatically increase the air supply wind intensity and optimize the air supply direction to achieve better temperature control effect.

[0046] Assuming that the fan has three air supply modes, after the fan is started, the fan system first detects whether the user has enabled the comfort wind function, and executes at the default speed or gear before the detection is completed. On the contrary, if the comfort wind function is enabled, the system will monitor and obtain the user's current status in real time to dynamically adjust the air supply mode to ensure that the user is always in the most suitable air supply environment.

[0047] The fan provided by the embodiment of the present invention can intelligently switch the air supply mode by judging the user's status: data collection: when the fan is started for the first time, the thermal imaging sensor and the camera will perform a comprehensive scan to obtain the initial state of the room. Regular detection: the system can be set to perform a detection at regular intervals (for example, every 5 minutes) to update the user's body temperature and activity status. When the user's activity changes: when the system detects that the user changes from a stationary state to a moving state, or from a moving state to a stationary state, a detection will be performed immediately.

[0048] like Figure 1 to Figure 2 As shown, in an optional embodiment, based on the body surface temperature information T, distance information and ambient temperature information, controlling the fan to start and operate at a preset gear specifically includes: based on the body surface temperature information T in the range of 36.5°C to 37.5°C, determining that the user is in a normal state, and controlling the fan to operate at a medium speed gear; based on the body surface temperature information T>37.5°C, determining that the user is in a state after strenuous exercise, and controlling the fan to increase one gear on the basis of the medium speed gear, and operate at the first increased gear.

[0049] In this embodiment, a user's body surface temperature map is generated through thermal imaging sensor data, and an image showing the user's body surface temperature distribution is generated, so that you can intuitively see which parts have higher temperatures. If the user's body surface temperature exceeds a certain threshold (for example, 36°C), it is considered that the user may need to dissipate heat quickly. In addition, it is necessary to distinguish whether the rise in human body temperature is caused by illness or exercise. The distinction can be made through methods such as the speed and duration of temperature rise, the time point of temperature measurement, temperature distribution, and thermal imaging technology, so that the fan can accurately meet user needs.

[0050] Specifically, the user's body temperature will usually rise gradually after the start of exercise, and will gradually return to normal within a few minutes to half an hour after the exercise. As for the temperature rise caused by the user's illness, the temperature rise is usually slow and lasts for a long time, which may last for several hours or even days.

[0051] In addition, the body temperature of the user rises after exercise. The body temperature is usually higher when measured immediately after the user exercises, but it will gradually decrease over time. The body temperature of the user rises due to illness. The user's body temperature may be higher at multiple times of the day and change little, so as to determine whether the user's body temperature rise is caused by exercise or illness.

[0052] like Figure 1 to Figure 2 As shown, in some embodiments, the control method also includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by less than 0.3°C and the body surface temperature information T>37.5°C, the fan is controlled to increase by 1 gear on the basis of the first increase gear, until the highest gear.

[0053] In the above embodiment, by controlling the fan to increase one gear on the basis of the first increase gear, until the highest gear, the purpose of quickly dissipating heat for the user can be achieved, thereby controlling the user's body temperature within a comfortable temperature range and improving the user's experience.

[0054] like Figure 1 to Figure 2 As shown, in some embodiments, the control method further includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by ≥0.3°C and the body surface temperature information T>37.5°C, controlling the fan to maintain operation at the first increase gear.

[0055] In the above embodiment, by controlling the fan to maintain the first increase gear, the purpose of stable heat dissipation for the user can be achieved, thereby controlling the user's body temperature within a comfortable temperature range, reducing the physical discomfort caused by the rapid drop in the user's body temperature, for example, reducing the user's cold caused by the rapid drop in the user's body temperature, and improving the user's experience.

[0056] like Figure 1 to Figure 2 As shown, in some embodiments, the control method also includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by less than 0.3°C, and the body surface temperature information T is in the range of 36.5°C to 37.5°C, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at a medium speed gear.

[0057] In the above embodiment, when the body surface temperature information T is in the range of 36.5°C to 37.5°C, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at the medium speed gear, which blows more comfortable wind to the user.

[0058] like Figure 1 to Figure 2 As shown, in some embodiments, the control method also includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by ≥0.3°C, and the body surface temperature information T is in the range of 36.5°C to 37.5°C, the fan is controlled to reduce one gear on the basis of the first increase gear and operate at a medium speed gear.

[0059] In the above embodiment, when the body surface temperature information T is in the range of 36.5℃~37.5℃, the fan is controlled to reduce one gear on the basis of the first increase gear and work at the medium speed gear, which blows more comfortable wind to the user. This intelligent air supply mode can not only be dynamically adjusted according to the actual needs of the user, but also provide a more personalized comfort experience without affecting other activities of the user.

[0060] like Figure 1 to Figure 2As shown, in some embodiments, the control method further includes: real-time monitoring of body surface temperature information T; based on the body surface temperature information T decreasing by ≥0.3°C and the body surface temperature information T being lower than 36.5°C, controlling the fan to stop working.

[0061] In this embodiment, the body surface temperature information T is lower than 36.5° C., indicating that the user does not need to cool down at this time. By controlling the fan to stop working, the user's body temperature can be further reduced to reduce the user's physical discomfort.

[0062] like Figure 1 to Figure 2 As shown, in some embodiments, the control method also includes: based on the fan not detecting a user for a first consecutive preset time, controlling the fan to operate at a low speed; based on the fan not detecting a user for a second consecutive preset time, controlling the fan to stop, wherein the second preset time is greater than the first preset time.

[0063] In this embodiment, when the infrared imaging detector detects that there is no human body for 5 consecutive minutes, the current comfortable wind gear is directly reduced to low speed gear 1, and it is determined that the user has left the air supply area at this time. In order to save energy, the comfortable wind low speed gear 1 is intelligently executed;

[0064] When the infrared imaging detector is set to continuously detect time > Y min and there is no user in the air supply area, the gear will immediately shut down and stop working. It will continuously detect that there is no user in the air supply area for Y min. The user can set the Y min time setting on the fan App.

[0065] like Figure 1 to Figure 2 As shown, in an optional implementation, the control method further includes: recalculating the second preset time based on detecting body surface temperature information T for a third preset time continuously after the fan fails to detect the user.

[0066] In this embodiment, when the infrared imaging detector continuously detects that there is no user in the air supply area, if the user's body temperature is detected for 10 consecutive seconds, the Y min automatic shutdown time for continuous detection of no user is reset.

[0067] like Figure 1 to Figure 2 As shown, in an optional embodiment, the ambient temperature information defaults to 25°C, and the control method further includes: for every 5°C increase in the ambient temperature information, the fan increases by 1 gear on the current gear; for every 5°C decrease in the ambient temperature information, the fan decreases by 1 gear on the current gear.

[0068] In this embodiment, the fan operates in an ambient temperature range of (3°C, 40°C). The current model is in an experimental environment of 25°C, and the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is installed with an infrared thermal imaging detector to monitor changes in the user's body temperature in real time, and intelligently adjust the comfortable wind supply gear. The comfortable wind gear is compensated and adjusted by detecting the ambient temperature, ensuring that the user's body can feel the most comfortable wind experience under different body conditions.

[0069] like Figure 1 to Figure 2 As shown, in an optional implementation, the distance information defaults to 2m, and the control method further includes: for every 1m increase in the distance information, the fan increases by 1 gear on the current gear; for every 1m decrease in the distance information, the fan decreases by 1 gear on the current gear.

[0070] In this embodiment, the fan uses an air supply distance range (0m, 3m), and the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is installed with an infrared thermal imaging detector to monitor the distance information in real time and intelligently adjust the comfortable wind supply gear. The comfortable wind gear is compensated and adjusted by detecting the air supply distance to ensure that the distance information can feel the most comfortable wind experience under different conditions.

[0071] Specifically, under the experimental environment of 25℃ and the air supply distance of 2m from the person, the most comfortable wind speed of the current model is set to the default gear, that is, the fan initial gear is medium speed gear 3, then the fan is equipped with an infrared thermal imaging detector to monitor the user's body temperature changes in real time, and intelligently adjust the comfortable wind supply gear. By detecting the air supply distance and the ambient temperature range, the comfortable wind gear is compensated and adjusted to ensure that the user can feel the most comfortable wind experience under different body conditions;

[0072] The circulation fan is equipped with an infrared thermal imaging detector to detect the ambient temperature, air supply distance, and changes in the user's body temperature in real time, and intelligently adjust the comfortable air supply level to ensure that the user can experience the most comfortable wind in real time;

[0073] The fan has 5 comfortable wind speed settings, which are divided into low speed, medium speed and high speed according to the speed. Gears 1 and 2 are defined as low speed; gear 3 is defined as medium speed; gears 4 and 5 are defined as high speed. Under the experimental environment of 25℃ and the air supply distance of 2m from people, the most comfortable wind speed of the current model is set to the default gear, that is, the fan's initial gear is medium speed gear 3. The fan is equipped with an infrared thermal imaging detector, which scans the fan's air supply area at the same time, obtains and detects the ambient temperature, air supply distance and human body temperature, and intelligently determines and adjusts the execution of the comfortable wind supply gear, truly meeting the user's wind sensation needs at different body temperature states.

[0074] The normal body temperature of a user is 36.5℃~37.5℃. Infrared imaging can detect the user's body temperature in three conditions:

[0075] Condition 1: When the infrared imaging detector detects that the user's body temperature is between 36.5℃ and 37.5℃, it is determined that the user's body is in a normal state; at this time, the comfort wind gear is in the medium speed gear 3, providing the user with the most comfortable wind feeling experience;

[0076] Condition 2: After strenuous exercise, when infrared imaging detects that the user's body temperature T>37.5℃, it is determined that the user's body is in a state of strenuous exercise; the initial comfort wind gear is 3 gears, and 1 gear is increased, and the 4 gear is operated. The infrared imaging detector continuously detects the user's body temperature and obtains the user's body temperature every 5 minutes. When it is detected that the user's body temperature drops by <0.3℃ compared with the last detected temperature, it is determined that the user's temperature has not dropped significantly; when it is detected that the temperature drops by ≥0.3℃ compared with the last detected temperature, it is determined that the user's temperature has dropped significantly;

[0077] When it is detected that the user's body temperature drops by less than 0.3℃, the body temperature does not drop significantly and T>37.5℃, the gear will be raised by one gear, and the cycle will continue until the highest gear is reached;

[0078] When it is detected that the user's body temperature drops by ≥0.3℃, and the body temperature drops significantly but is still T>37.5℃, the gear will maintain the 4th gear;

[0079] When it is detected that the user's body temperature drops by less than 0.3℃, and the body temperature does not drop significantly to the range of 36.5℃ to 37.5℃, the gear is reduced by 1 gear to the medium speed gear 3;

[0080] When the user's body temperature drops by ≥0.3℃ and drops to the range of 36.5℃~37.5℃, the gear will be immediately lowered by 1 gear and the medium speed 3 gear will be executed;

[0081] When the user's body temperature drops by ≥0.3℃ and the temperature is lower than 36.5℃, the fan gear stops immediately;

[0082] Condition 3: The infrared imaging detector detects the user's body temperature every 5 minutes. If no user's body condition is detected for 5 consecutive minutes, the comfortable wind level is intelligently matched:

[0083] (1) When the infrared imaging detector detects that there is no human body for 5 consecutive minutes, the current comfort wind speed is directly reduced to low speed gear 1, and it is determined that the user has left the air supply area. In order to save energy, the comfort wind low speed gear 1 is intelligently executed;

[0084] (2) When the infrared imaging detector continuously detects that there is no user in the air supply area for more than Y min, the fan will immediately shut down and stop working. The fan will continuously detect that there is no user in the air supply area for Y min. The user can set the Y min time setting on the fan app.

[0085] (3) When the infrared imaging detector continuously detects that there is no user in the air supply area, if the user's body temperature is detected for 10 consecutive seconds, the Y min automatic shutdown time for continuous detection of no user will be reset;

[0086] The fan operating environment temperature range is (3°C, 40°C). For the current model, under the experimental environment of 25°C and the air supply distance to people of 2m, the most comfortable wind speed is set to the default gear, that is, the fan initial gear is medium speed gear 3. For every increase / decrease of 5°C, the current gear is increased / decreased by 1 gear.

[0087] The fan uses an air supply distance range of (0m, 3m). For the current model, under the experimental environment of 25°C and an air supply distance of 2m from a person, the most comfortable wind speed is set to the default gear, that is, the fan's initial gear is medium speed gear 3. For every increase / decrease of 1m in the air supply distance, the current gear is increased / decreased by 1 gear.

[0088] In addition, the order of the steps in the above embodiments is only a preferred embodiment of the present application. Without conflicting with the inventive concept of the present application, the order of the steps can be freely changed, and such adjustment falls within the protection scope of the embodiments of the present application.
