Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular provides an aroma control method for an air conditioner. Background Art

[0002] As people's living standards improve, air conditioners are becoming increasingly common in their daily lives and work. People's requirements for air conditioners and the air quality of indoor spaces are also increasing. Currently, an aromatherapy device is typically installed on the indoor unit of an air conditioner. The aromatherapy device contains a fragrance material that can emit fragrance. When air flows through the aromatherapy device, the fragrance emitted by the fragrance material is carried into the indoor space. This not only adjusts the temperature of the indoor space through the air conditioner, but also improves the air quality of the indoor space. For example, the aromatherapy device can be installed on the filter of the indoor unit of the air conditioner. When air enters the indoor unit through the filter, the fragrance emitted by the fragrance material is carried into the air duct of the indoor unit of the air conditioner. After the air conditioner adjusts the temperature, the fragrance enters the indoor space, thereby achieving the purpose of adjusting the temperature and air quality of the indoor space.

[0003] However, the fragrance of these aromatherapy devices relies primarily on the contact between the aromatherapy material and the air, which then carries it into the room. The rate at which the fragrance is released depends on factors such as the volatilization rate of the aromatherapy material, the air velocity, and the contact area and duration between the air and the aromatherapy material. These factors are generally uncontrollable. As a result, in different application scenarios, the fragrance in the room often fails to reach a reasonable concentration, resulting in a fragrance that is either too strong or too weak, failing to meet user needs and leading to a poor user experience.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem in the prior art that the fragrance emission speed of the fragrance diffuser is uncontrollable, resulting in the fragrance in the indoor space being too strong or too weak.

[0009] In the preferred technical solution of the above-mentioned aromatherapy control method, the step of "controlling the operating parameters of the aromatherapy device based on the second comparison result" further includes: if the area is greater than the second preset area, controlling the atomizer to operate at a second atomization rate, and controlling the fan to operate at a second speed; wherein, the second atomization rate is less than or equal to the first atomization rate, and the second speed is less than or equal to the first speed.

[0010] In the preferred technical solution of the above-mentioned aromatherapy control method, the step of "controlling the operating parameters of the aromatherapy device based on the second comparison result" further includes: if the area is less than or equal to the second preset area, controlling the atomizer to operate at a third atomization rate, and controlling the fan to operate at a third speed; wherein the third atomization rate is less than or equal to the second atomization rate, and the third speed is less than or equal to the second speed.

[0011] In the preferred technical solution of the above aroma control method, the aroma control method further comprises: the atomization rate of the atomizer increases as the current flowing through the atomizer increases.

[0012] In the preferred technical solution of the above-mentioned aromatherapy control method, the aromatherapy control method further includes: after controlling the atomizer to start running, obtaining the running time of the atomizer; comparing the running time with a first preset time; if the running time is greater than or equal to the first preset time, controlling the atomizer to stop running; after controlling the atomizer to stop running, obtaining the first stop time of the atomizer stopping running; comparing the first stop time with a second preset time; if the first stop time is greater than or equal to the second preset time, controlling the atomizer to start running.

[0013] In the preferred technical solution of the above-mentioned aromatherapy control method, the aromatherapy control method further includes: after controlling the atomizer to start running, obtaining the running time of the atomizer; comparing the running time with a first preset time; if the running time is greater than or equal to the first preset time, controlling the atomizer to stop running; after controlling the atomizer to stop running, obtaining the first stop time of the atomizer stopping running; comparing the first stop time with a second preset time; if the first stop time is greater than or equal to the second preset time, controlling the atomizer to start running.

[0014] In a preferred technical solution of the above aroma control method, the aroma control method further comprises: controlling the atomizer to start running after controlling the atomizer to stop running for a fourth preset time period.

[0015] In a preferred technical solution of the above aroma control method, the aroma control method further comprises: after controlling the atomizer to stop running, controlling the fan to continue running for a fifth preset time period and then stop running.

[0016] In the technical solution of the present invention, an air conditioner includes a casing having an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. The air conditioner is equipped with an aromatherapy device, which is arranged in the air duct. The aromatherapy device includes a shell, an atomizer and a fan arranged in the shell. The shell is provided with an air outlet. The atomizer is configured to atomize the aromatherapy liquid reaching the atomizer into droplets, and the fan is configured to blow the droplets of aromatherapy liquid atomized by the atomizer out of the shell through the air outlet. In this way, the wind blown out by the fan can better and more fully blow out the droplets of aromatherapy liquid in the shell, so that the droplets of aromatherapy liquid atomized by the atomizer can be blown into the air duct and then enter the indoor space together with the air flowing through the air duct, thereby better improving the fragrance concentration in the indoor space, better meeting the needs of users, and enhancing the user experience.

[0017] The aromatherapy control method of the present invention includes obtaining the area of ​​the space where the air conditioner is located, comparing this area with a first preset area, and controlling the operating parameters of the aromatherapy device based on the first comparison result. The operating parameters of the aromatherapy device include at least one of the atomization rate of the atomizer and the speed of the fan. By controlling the operating parameters of the aromatherapy device based on the area of ​​the space where the air conditioner is located, the speed of fragrance dissemination from the aromatherapy liquid in the aromatherapy device can be better controlled, thereby better controlling the fragrance concentration in the indoor space, ensuring a more appropriate fragrance in the indoor space and improving the user experience.

[0018] If the area is larger than the first preset area, it means that the current indoor space is large and a larger amount of aromatherapy liquid is required to achieve a more suitable fragrance concentration in the indoor space. At this time, the atomizer is controlled to run at a larger first atomization rate and the fan is controlled to run at a higher first speed. In this way, the atomizer can atomize more aromatherapy liquid and the fan can blow out more wind. The wind can quickly blow the droplet-shaped aromatherapy liquid produced by the atomizer out of the housing and into the air duct, and then into the indoor space, so that the indoor space can reach a suitable fragrance concentration more quickly, thereby improving the user experience.

[0019] If the area is less than or equal to the first preset area, the area is further compared with the second preset area. If the area is greater than the second preset area, that is, the area is less than or equal to the first preset area and greater than the second preset area, it means that the area of ​​the current indoor space is a bit large, but not very large. A certain amount of aromatherapy liquid can make the indoor space reach a more suitable fragrance concentration. At this time, the atomizer is controlled to run at a slightly smaller second atomization rate, and the fan is controlled to run at a slightly lower second speed. In this way, the atomizer can atomize an appropriate amount of aromatherapy liquid, and the fan can blow out an appropriate amount of wind. These winds can blow the appropriate amount of droplet-shaped aromatherapy liquid produced by the atomizer out of the shell, into the air duct, and then into the indoor space, so that the indoor space can reach a suitable fragrance concentration at a faster speed, thereby improving the user experience.

[0020] If the area is less than or equal to the second preset area, it means that the area of ​​the current indoor space is small, and a smaller amount of aromatherapy liquid can make the indoor space reach a more suitable fragrance concentration. At this time, the atomizer is controlled to run at a smaller third atomization rate, and the fan is controlled to run at a lower third speed. In this way, the atomizer can only atomize less aromatherapy liquid, and the fan can blow out less wind. However, since the amount of droplets of aromatherapy liquid atomized by the atomizer is small, the wind blown by the fan is sufficient to blow the droplets of aromatherapy liquid atomized by the atomizer out of the shell, into the air duct, and then into the indoor space, so that the indoor space can reach a suitable fragrance concentration at a faster speed, thereby improving the user experience.

[0021] Furthermore, after the atomizer is controlled to start running, the running time of the atomizer is obtained, and the running time is compared with the first preset time. If the running time is greater than or equal to the first preset time, it means that the current running time of the atomizer is relatively long, and there is already a lot of droplet-shaped aromatherapy liquid atomized by the atomizer in the shell. In order to avoid an excessive amount of droplet-shaped aromatherapy liquid in the shell and re-condense into liquid aromatherapy liquid in the shell, at this time, the atomizer is controlled to stop running and no longer atomizes the aromatherapy liquid through the atomizer. After controlling the atomizer to stop running, obtain the first stop time of the atomizer stopping running, compare the first stop time with the second preset time, if the first stop time is greater than or equal to the second preset time, it means that the atomizer has stopped running for a period of time, and as time goes by, the droplet-shaped fragrance liquid in the shell has basically been discharged from the shell into the air duct and brought into the indoor space. At this time, the atomizer is controlled to start running, and the fragrance liquid is atomized by the atomizer. The newly generated droplet-shaped fragrance liquid will continue to be discharged to the outside of the shell, and then enter the indoor space with the air in the air duct, thereby increasing the fragrance concentration of the indoor space, so that the fragrance of the indoor space reaches a more suitable concentration as soon as possible, and improves the user experience. Through the above control method, the droplet-shaped fragrance liquid produced by the atomizer can be fully discharged from the shell, the utilization rate of the fragrance liquid can be improved, the fragrance of the indoor space can be better controlled at a more suitable concentration, and the user experience can be improved.

[0022] Furthermore, the cumulative running time of the atomizer from the first startup to the current time is obtained, and it is determined whether the cumulative running time is greater than or equal to the third preset time. If the cumulative running time is greater than or equal to the third preset time, it means that the cumulative running time of the atomizer is relatively long, and the fragrance in the indoor space has reached a more suitable concentration. If it continues to run, it may cause the fragrance in the indoor space to be too strong. At this time, the atomizer is controlled to stop running, and the fragrance liquid is no longer atomized through the atomizer. If the cumulative running time is less than the third preset time, it means that the cumulative running time of the atomizer is not long enough, and the fragrance in the indoor space has not reached a suitable concentration. At this time, the atomizer is controlled to continue running, and the fragrance liquid is continued to be atomized through the atomizer, so that the indoor space can reach a suitable fragrance concentration as soon as possible, thereby improving the user experience. Through the above control method, the fragrance in the indoor space can be better controlled at a more suitable concentration, thereby improving the user experience.

[0023] After the atomizer is controlled to stop running for the fourth preset time, the atomizer has stopped running for a while. As time goes by, the fragrance concentration in the indoor space gradually fades. At this time, the atomizer is controlled to start running, and the fragrance liquid is atomized by the atomizer. The droplet-shaped fragrance liquid enters the indoor space with the air in the air duct, thereby improving the fragrance concentration in the indoor space, so that the fragrance in the indoor space is controlled at a more appropriate concentration, and improving the user experience.

[0024] Furthermore, after the atomizer is controlled to stop running, the atomizer no longer atomizes the fragrance liquid, but some droplets of the fragrance liquid will still remain in the shell. At this time, the fan is controlled to continue running for the fifth preset time and then stop running. The wind blown by the fan blows out the droplets of the fragrance liquid remaining in the shell, thereby avoiding waste of the fragrance liquid and improving the utilization rate of the fragrance liquid.

[0040] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Although this embodiment uses a cabinet air conditioner as an example, it is also applicable to other types of air conditioners, such as ceiling-mounted air conditioners and wall-mounted air conditioners.

[0041] It should be noted that, in the description of the present invention, the terms "upper", "lower", "left", "right", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are merely for the convenience of description and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", "fourth" and "fifth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, it should be noted that, in the description of the present application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0042] Currently, the fragrance of aromatherapy devices primarily relies on the contact between the aromatherapy material and the air, which then carries it into the indoor space. The rate at which the fragrance is released is related to the volatilization rate of the aromatherapy material, the air velocity, the contact area and duration between the air and the aromatherapy material, and other factors. However, these factors are generally uncontrollable, which can easily lead to the fragrance in the indoor space being too strong or too weak, resulting in a poor user experience. Therefore, the aromatherapy control method of the present invention controls the operating parameters of the aromatherapy device based on the size of the space where the air conditioner is located, thereby controlling the fragrance concentration in the indoor space to a more appropriate concentration range and improving the user experience.

[0043] In the present invention, the cabinet air conditioner includes a casing, which has an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. The cabinet air conditioner is equipped with an aromatherapy device, which is arranged in the air duct. The aromatherapy device includes a shell, an atomizer and a fan arranged in the shell. The shell is provided with an air outlet. The atomizer is configured to atomize the aromatherapy liquid reaching the atomizer into droplets, and the fan is configured to blow the droplets of aromatherapy liquid atomized by the atomizer out of the shell through the air outlet. In this way, the wind blown out by the fan can better and more fully blow out the droplets of aromatherapy liquid in the shell, so that the droplets of aromatherapy liquid atomized by the atomizer can be blown into the air duct, and then enter the indoor space together with the air flowing through the air duct, thereby better improving the fragrance concentration in the indoor space, better meeting the needs of users, and enhancing the user experience.

[0044] It should be noted that the atomizer can be, but is not limited to, a microporous atomizer, a ceramic atomizer, etc. In this application, the atomizer utilizes high-frequency oscillation of ions and high-frequency resonance of the atomizer to break up the molecular structure of the aromatherapy liquid and generate droplets.

[0045] It should be noted that the fan may be, but is not limited to, an axial flow fan, a centrifugal fan, etc.

[0046] Since the floor height of the indoor space is usually relatively fixed, even if there is a difference, it will not be too big. Therefore, when controlling the aroma concentration, the fragrance concentration of the indoor space can be controlled by considering the size of the plane area of ​​the indoor space.

[0047] In the present invention, the cabinet air conditioner is provided with a detection device, through which the area of ​​the indoor space where the cabinet air conditioner is located can be detected.

[0048] Currently, the plane shape of indoor spaces is typically rectangular or square. For example, consider an ultrasonic detection device. A cabinet air conditioner is placed in a corner of the room, backed against a wall. The ultrasonic device is mounted on the front side of the cabinet air conditioner. During detection, the ultrasonic device is controlled to emit ultrasonic waves along the wall opposite the cabinet air conditioner and along the wall opposite the cabinet air conditioner. A timer begins as the ultrasonic wave is emitted. The ultrasonic wave propagates through the air, reflects off an obstacle, and then returns. The ultrasonic receiver stops the timer when it receives the reflected wave. The propagation speed of ultrasonic waves in air is approximately 340 m / s. Based on the time t recorded by the timer, the distance (s) from the ultrasonic emission point to the obstacle can be calculated: s = 340t / 2. This allows the distance between the front side of the cabinet air conditioner and the wall opposite it, as well as the dimensions of the wall opposite the cabinet air conditioner, thereby determining the dimensions of the two perpendicular walls of the room. Multiplying these two dimensions together determines the area of ​​the room.

[0049] It should be noted that the above-mentioned detection device can also be, but is not limited to, a radar sensor, a laser sensor, an infrared detector, etc.

[0050] To achieve all the functions of the aromatherapy control method described below, the cabinet air conditioner in the present invention further includes a control unit, which is connected to the detection device, the atomizer, and the fan, respectively, and is capable of controlling the atomization rate of the aromatherapy component and the speed of the fan based on the size of the acquired area. It should be noted that this control unit can physically be a control chip inherent to the cabinet air conditioner, a controller specifically designed to execute the aromatherapy control method of this application, or a functional module or unit of a general controller.

[0051] Refer to the following Figures 1 to 4 To illustrate possible implementations of the aroma control method for an air conditioner of the present invention.

[0052] like Figure 1As shown, in one possible embodiment, the aroma control method of the present invention includes:

[0053] S100: Obtaining the area of ​​the space where the cabinet air conditioner is located;

[0054] S101: Compare the area with a first preset area;

[0055] S102: Based on the first comparison result, controlling the atomization rate of the atomizer and the rotation speed of the fan.

[0056] In S100, the area of ​​the space where the cabinet air conditioner is located is obtained by the above-mentioned detection device.

[0057] In S101, based on the area obtained in S100, the area is compared with a first preset area. For example, the area obtained in S100 is 24m 2 , the first preset area is 30m 2 .

[0058] In S102, based on the first comparison result in S101, the atomization rate of the atomizer and the speed of the fan are controlled. By controlling the atomization rate of the atomizer and the speed of the fan, the amount of droplet-shaped aromatherapy liquid delivered into the air duct is controlled, thereby controlling the concentration of the fragrance in the indoor space.

[0059] Through the above control method, the atomization rate of the atomizer and the speed of the fan are controlled according to the size of the area of ​​the space where the cabinet air conditioner is located, so that the fragrance distribution speed of the fragrance liquid of the aromatherapy device can be better controlled, and the concentration of the fragrance in the indoor space can be better controlled, so that the fragrance in the indoor space is more suitable and the user experience is improved.

[0060] It should be noted that, based on the first comparison result between the area of ​​the space where the cabinet air conditioner is located and the first preset area, it is also possible to control only the atomization rate of the atomizer or the speed of the fan. When only the atomization rate of the atomizer is controlled, in this case, the fan can run at a relatively fixed speed. However, such a control method may have the problem that when the atomization rate of the atomizer is large, the fan speed is too low and the mist droplet-shaped fragrance liquid in the shell cannot be blown out in time, resulting in low utilization rate of the fragrance liquid. When only the speed of the fan is controlled, in this case, the atomizer can run at a relatively fixed atomization rate. However, such a control method may have the problem that when the area of ​​the indoor space is large, the atomization rate of the fragrance liquid is too low, resulting in the fragrance of the indoor space being too light, or when the area of ​​the indoor space is small, the atomization rate of the fragrance liquid is too high, resulting in the fragrance of the indoor space being too strong.

[0061] like Figure 2 As shown, in a preferred embodiment, the aroma control method of the present invention includes:

[0062] S200: Obtaining the area of ​​the space where the cabinet air conditioner is located;

[0063] S201: Determine whether the area is greater than a first preset area. If so, execute S202; if not, execute S203;

[0064] S202: Controlling the atomizer to operate at a first atomization rate and controlling the fan to operate at a first speed;

[0065] S203: further determining whether the area is greater than a second preset area, if so, executing S204; if not, executing S205;

[0066] S204: Controlling the atomizing element to operate at a second atomizing rate and controlling the fan to operate at a second speed;

[0067] S205: Control the atomizing element to operate at a third atomizing rate, and control the fan to operate at a third speed.

[0068] In S200 , similar to S100 , the area of ​​the space where the cabinet air conditioner is located is obtained by the above-mentioned detection device.

[0069] In S201, based on the area obtained in S200, it is determined whether the area is greater than a first preset area. If the area is greater than the first preset area, for example, the area is 35m 2 , the first preset area is 30m 2 . This indicates that the area of ​​the current indoor space is large, and a larger amount of aromatherapy liquid is required to enable the indoor space to reach a more suitable fragrance concentration. At this time, the atomizer is controlled to run at a larger first atomization rate, and the fan is controlled to run at a higher first speed, that is, S202 is executed. For example, the first atomization rate is 0.03ml / min, and the first speed is 860rpm. In this way, the atomizer can atomize more aromatherapy liquid, and the fan can blow out more wind. These winds can quickly blow the droplet-shaped aromatherapy liquid produced by the atomizer out of the shell, into the air duct, and then into the indoor space, so that the indoor space can reach a suitable fragrance concentration more quickly, thereby improving the user experience.

[0070] If the area is less than or equal to the first preset area, it is further determined whether the area is greater than the second preset area. If the area is greater than the second preset area, that is, the area is less than or equal to the first preset area and greater than the second preset area. For example, the area is 24m 2 , the first preset area is 30m 2 , the second preset area is 15m 2. This indicates that the area of ​​the current indoor space is a bit large, but not very large. A certain amount of aromatherapy liquid can make the indoor space reach a more appropriate fragrance concentration. At this time, the atomizer is controlled to run a slightly smaller second atomization rate, and the fan is controlled to run a slightly lower second speed, that is, S204 is executed. Among them, the second atomization rate is less than or equal to the first atomization rate, and the second speed is less than or equal to the first speed. For example, the second atomization rate is 0.02ml / min, and the first speed is 660rpm. In this way, the atomizer can atomize an appropriate amount of aromatherapy liquid, and the fan can blow out an appropriate amount of wind. These winds can blow the appropriate amount of droplet-shaped aromatherapy liquid produced by the atomizer out of the shell, into the air duct, and then into the indoor space, so that the indoor space can reach an appropriate fragrance concentration at a faster speed, thereby improving the user experience.

[0071] If the area is less than or equal to the second preset area, for example, the area is 12m 2 , the second preset area is 15m 2 . This indicates that the area of ​​the current indoor space is relatively small, and a smaller amount of aromatherapy liquid can make the indoor space reach a more suitable fragrance concentration. At this time, the atomizer is controlled to run at a smaller third atomization rate, and the fan is controlled to run at a lower third speed, that is, S205 is executed. Among them, the third atomization rate is less than or equal to the second atomization rate, and the third speed is less than or equal to the second speed. For example, the third atomization rate is 0.01ml / min, and the first speed is 540rpm. In this way, the atomizer can only atomize less aromatherapy liquid, and the fan can blow out less wind. However, since the amount of droplet-shaped aromatherapy liquid atomized by the atomizer is small, the wind blown by the fan is sufficient to blow the droplet-shaped aromatherapy liquid atomized by the atomizer out of the shell, into the air duct, and then into the indoor space, so that the indoor space can reach a suitable fragrance concentration at a faster speed, thereby improving the user experience.

[0072] Through the above control method, the amount of aromatherapy liquid entering the indoor space is controlled according to the actual area of ​​the indoor space, so that the fragrance concentration of the indoor space can be controlled more accurately and the user experience is improved.

[0073] It should be noted that when the area is less than or equal to the first preset area, it is also possible to not further determine whether the area is greater than the second preset area, but directly control the atomizer to operate at a smaller second atomization rate or third atomization rate, and control the fan to operate at a smaller second speed or third speed. However, these control methods may have the problem of the atomizer atomization rate being too high or the fan speed being too high when the actual area of ​​the indoor space is small, or the atomizer atomization rate being too low or the fan speed being too low when the actual area of ​​the indoor space is large, resulting in the fragrance in the indoor space being too strong or too weak.

[0074] It should be noted that when the area is less than or equal to the second preset area, the atomizer can also be controlled to run at the second atomization rate and the fan can be controlled to run at the second speed. However, this control method may cause the atomizer to have a high atomization rate when the area is too small, resulting in the fragrance in the indoor space being too strong.

[0075] In one possible embodiment, the atomization rate of the atomizer increases as the current flowing through the atomizer increases. In other words, as the current flowing through the atomizer increases, the atomization rate of the atomizer increases accordingly. In this way, the atomization rate of the atomizer can be controlled simply by controlling the magnitude of the current flowing through the atomizer, which is simple and convenient.

[0076] It should be noted that the atomization rate of the atomizer can also be controlled by other means, for example, controlling the voltage of the power supply to the atomizer, etc. Without departing from the principles of the present application, those skilled in the art can flexibly select a specific method for controlling the atomization rate of the atomizer according to the specific application scenario, as long as the atomization rate of the atomizer can be accurately controlled.

[0077] like Figure 3 As shown, in one possible embodiment, the aroma control method of the present invention includes:

[0078] S300: After the atomizer is started, the operating time of the atomizer is obtained;

[0079] S301: Determine whether the running time is greater than or equal to a first preset time. If so, execute S303; if not, execute S302;

[0080] S302: Control the atomizing element to continue operating;

[0081] S303: Control the atomizing element to stop running;

[0082] S304: After the atomizer is controlled to stop operating, obtaining a first stop time duration of the atomizer;

[0083] S305: Determine whether the first stop duration is greater than or equal to the second preset duration. If so, execute S306; if not, execute S307;

[0084] S306: Control the atomizing element to start operation;

[0085] S307: Control the atomizing element to continue to stop running.

[0086] In S300 , after the atomizer is controlled to start operation, that is, after S202 , S204 , and S205 , the operation time of the atomizer is obtained.

[0087] In S301, based on the running time obtained in S300, it is determined whether the running time is greater than or equal to a first preset time. If the running time is greater than or equal to the first preset time, for example, the running time is 12 seconds and the first preset time is 10 seconds, it means that the current operation time of the atomizer has been relatively long, and a large amount of droplet-shaped aromatherapy liquid atomized by the atomizer has been stored in the shell. In order to prevent the excessive amount of droplet-shaped aromatherapy liquid in the shell from re-condensing into liquid aromatherapy liquid fluid in the shell, the atomizer is controlled to stop running, that is, S303 is executed, and no more droplet-shaped aromatherapy liquid is atomized by the atomizer.

[0088] If the running time is less than the first preset time, for example, if the running time is 5 seconds and the first preset time is 10 seconds, it means that the current operation time of the atomizer is still relatively short and the fragrance in the room has not yet reached the appropriate concentration. In this case, the atomizer is controlled to continue operating, that is, executing S302. The atomizer continues to atomize the fragrance liquid so that the room can reach the appropriate fragrance concentration as soon as possible, thereby improving the user experience.

[0089] In S304 , after the atomizer is controlled to stop operating, that is, after S303 is executed, a first stop time duration of the atomizer stopping operating is obtained.

[0090] In S305, based on the first stop duration obtained in S304, it is determined whether the first stop duration is greater than or equal to the second preset duration. If the first stop duration is greater than or equal to the second preset duration, for example, the first stop duration is 3 minutes and 15 seconds, and the second preset duration is 3 minutes. This indicates that the atomizer has stopped running for a period of time. As time goes by, the mist droplet-shaped fragrance liquid in the shell has basically been discharged from the shell into the air duct and brought into the indoor space. At this time, the atomizer is controlled to start running, that is, S306 is executed. The fragrance liquid continues to be atomized by the atomizer, and the newly generated mist droplet-shaped fragrance liquid will continue to be discharged to the outside of the shell, and then enter the indoor space with the air in the air duct, thereby increasing the fragrance concentration in the indoor space, so that the fragrance in the indoor space reaches a more suitable concentration as soon as possible, and improving the user experience.

[0091] If the first stop time is shorter than the second preset time, for example, the first stop time is 2 minutes and the second preset time is 3 minutes, it means that the atomizer has not been in operation for a long time and some droplets of aromatherapy liquid generated by atomization of the atomizer have not yet been discharged from the housing. In this case, the atomizer is controlled to continue to stop operation, i.e., S307 is executed, and no more droplets of aromatherapy liquid are generated by atomization of the atomizer.

[0092] Through the above control method, the operation of the atomizer is controlled in an alternating manner of starting and stopping, so that the droplet-shaped fragrance liquid produced by the atomizer can be fully discharged from the shell, preventing the droplet-shaped fragrance liquid from re-condensing into fragrance liquid fluid in the shell, thereby improving the utilization rate of the fragrance liquid, better controlling the fragrance of the indoor space at a more appropriate concentration, and improving the user experience.

[0093] It should be noted that the atomizer can also be operated in other ways. For example, after the atomizer is controlled to start operating, it is controlled to remain in operation until the cabinet air conditioner stops operating. However, this control method may cause the atomizer to remain in operation for too long, resulting in a large amount of mist droplets of fragrance liquid being retained in the housing. The excessive mist droplets of fragrance liquid will re-condense into fragrance liquid fluid, resulting in low utilization rate of the fragrance liquid.

[0094] like Figure 4 As shown, in one possible embodiment, the aroma control method of the present invention includes:

[0095] S400: Obtaining the cumulative running time of the atomizer from the first startup to the current time;

[0096] S401: Determine whether the accumulated running time is greater than or equal to a third preset time. If so, execute S403; if not, execute S402;

[0097] S402: Control the atomizing element to continue operating;

[0098] S403: Control the atomizing element to stop running;

[0099] S404: After the atomizer is controlled to stop operating, a second stop time duration of the atomizer stopping operating is obtained;

[0100] S405: Determine whether the second stop duration is greater than or equal to the fourth preset duration. If so, execute S406; if not, execute S407;

[0101] S406: Control the atomizing element to start operation;

[0102] S407: Control the atomizing element to continue to stop running.

[0103] In S400 , the timing starts from the time when the atomizer is first started to the current time, and the timing stops to obtain the cumulative running time of the atomizer from the first start to the current time.

[0104] In S401, based on the accumulated running time obtained in S400, it is determined whether the accumulated running time is greater than or equal to a third preset time. If the accumulated running time is greater than or equal to the third preset time, for example, the accumulated running time is 1 hour and 20 minutes, and the third preset time is 1 hour, it means that the atomizer has been running for a long time since the first startup, and the atomizer has atomized a large amount of fragrance liquid and sent it into the indoor space. The fragrance concentration in the indoor space is already in a more appropriate concentration range. At this time, the atomizer is controlled to stop running, that is, S403 is executed, and the fragrance liquid is no longer atomized by the atomizer to prevent the fragrance in the indoor space from being too strong.

[0105] If the accumulated operating time is less than the third preset time, for example, the accumulated operating time is 45 minutes and the third preset time is 1 hour, it means that the atomizer has not been running for a long time since the first startup operation, the amount of fragrance liquid delivered to the indoor space is still relatively small, and the fragrance concentration in the indoor space is still relatively weak. In this case, the atomizer is controlled to continue operating, that is, S402 is executed to continue atomizing the fragrance liquid through the atomizer and delivering it to the indoor space, thereby increasing the fragrance concentration in the indoor space.

[0106] In S404 , after the atomizer stops operating, that is, after S403 , a second stop time duration of the atomizer stopping operating is obtained.

[0107] In S405, based on the second stop time obtained in S404, it is determined whether the second stop time is greater than or equal to the fourth preset time. If the second stop time is greater than or equal to the fourth preset time, for example, the second stop time is 3 hours and the fourth preset time is 2 hours. This indicates that the atomizer has stopped running for some time. As time goes by, the fragrance concentration in the indoor space gradually fades. At this time, the atomizer is controlled to start running, that is, S406 is executed. The aromatherapy liquid is atomized by the atomizer, and the droplet-shaped aromatherapy liquid enters the indoor space along with the air in the air duct, thereby increasing the fragrance concentration in the indoor space, so that the fragrance in the indoor space reaches a more suitable concentration as soon as possible, and improves the user experience.

[0108] If the second stop time is less than the fourth preset time, for example, the second stop time is 1 hour and 30 minutes and the fourth preset time is 2 hours, it means that the atomizer has not been stopped for a long time and the fragrance concentration in the room is still within a relatively suitable range. If the atomizer is restarted, the fragrance in the room may be too strong. In this case, the atomizer is controlled to continue to stop, that is, S407 is executed, and the fragrance liquid is no longer atomized by the atomizer.

[0109] Through the above control method, the start-up or stop of the atomizer is controlled according to the accumulated running time of the atomizer and the second stop time of the atomizer, so that the fragrance in the indoor space can be better controlled at a more appropriate concentration, thereby improving the user experience.

[0110] It should be noted that the operating state of the atomizer can be controlled not according to the cumulative operating time of the atomizer. For example, after the atomizer is controlled to start running, it can be controlled to keep running until the cabinet air conditioner stops running. However, this control method may cause the atomizer to keep running for too long, and the amount of atomized fragrance liquid is too much, resulting in too high a fragrance concentration in the indoor space. Obviously, after the atomizer is controlled to stop running, the atomizer can also be stopped, that is, after executing S403, S404 to S407 can also be omitted. However, this control method may cause the fragrance concentration in the indoor space to gradually fade over time.

[0111] In one possible embodiment, after the atomizer is controlled to stop operating, that is, after executing S303, S307, S403, and S407, the atomizer no longer atomizes the fragrance liquid, but some droplets of fragrance liquid still remain in the housing. In this case, the fan is controlled to continue operating for a fifth preset time period, for example, 3 minutes, and then stop. The air blown by the fan blows out the droplets of fragrance liquid remaining in the housing, thereby avoiding waste of the fragrance liquid and improving the utilization rate of the fragrance liquid.

[0112] It should be noted that the specific examples of the first atomization rate, the second atomization rate, the third atomization rate, the first rotational speed, the second rotational speed, the third rotational speed, the operating time, the cumulative operating time, the first stop time, the second stop time, the first preset time, the second preset time, the third preset time, the fourth preset time, and the fifth preset time are merely exemplary descriptions and are not restrictive. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific values ​​of each atomization rate, each rotational speed, the operating time, the cumulative operating time, each stop time, and each preset time according to the specific application scenario, as long as the fragrance concentration in the indoor space can be controlled within a relatively suitable range.

[0113] In summary, in the preferred technical solution of the present invention, by controlling the atomization rate and fan speed of the atomizer according to the size of the area of ​​the space where the air conditioner is located, the rate of fragrance release of the fragrance liquid of the aromatherapy device can be better controlled, the concentration of the fragrance in the indoor space can be better controlled, the fragrance in the indoor space can be more suitable, and the user experience can be improved. By increasing the atomization rate of the atomizer as the current flowing through the atomizer increases, the atomization rate of the atomizer can be more conveniently controlled. By controlling the operation of the atomizer in an alternating manner of starting and stopping the operation, the droplet-shaped fragrance liquid produced by the atomizer can be better discharged from the housing, the utilization rate of the fragrance liquid can be improved, the fragrance in the indoor space can be better controlled to a more suitable concentration, and the user experience can be improved. By controlling the operating state of the atomizer according to the cumulative operating time of the atomizer and the second stop time after the atomizer stops operating, the fragrance in the indoor space can be better controlled to a more suitable concentration, and the user experience can be improved. After the atomizing element is controlled to stop running, the fan is controlled to continue running for the fifth preset time period and then stop running, so that the mist droplet-shaped aromatherapy liquid in the shell can be fully blown out, thereby improving the utilization rate of the aromatherapy liquid.

[0114] Although the various steps in the above embodiment are described in the above-mentioned order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of this application.

[0115] Refer to the following Figures 5 to 12 To illustrate possible implementations of the aromatherapy device of the present invention.

[0116] like Figures 5 to 10 As shown and in accordance with Figure 9 In the illustrated configuration, a cabinet air conditioner (not shown) includes a housing having an air inlet and an air outlet, with an air duct formed between the inlet and the outlet. This allows air from the indoor space to enter the housing through the air inlet, be processed, and then return to the indoor space through the air duct and the air outlet, thereby regulating the indoor air conditions. The cabinet air conditioner is equipped with an aromatherapy device, which is positioned within the air duct. The aromatherapy device is then carried into the indoor space by the air flowing through the air duct, thereby improving the indoor fragrance.

[0117] The aromatherapy device includes a first shell 1, a liquid storage container 3, and aromatherapy liquid disposed in the liquid storage container 3. The first shell 1 includes a first base plate 12 and a first cover 11 that is inverted on the first base plate 12. A first mounting post 112 is disposed in the first cover 11, and a first mounting hole (not shown) is disposed on the first mounting post 112. A second mounting hole (not shown) is disposed on the first base plate 12. Fasteners (such as screws, bolts, etc.) pass through the second mounting hole and are connected to the first mounting hole. In this way, the first base plate 12 is disposed on the first cover 11, forming the first shell 1. An air inlet 121 and an air outlet 111 are disposed on the first shell 1. The air inlet 121 is roughly rectangular and disposed on the first base plate 12. The air outlet 111 is roughly circular and disposed on the side of the first cover 11 away from the first base plate 12 (i.e., Figure 9 ). The liquid storage container 3 is disposed in the first housing 1. The aromatherapy device also includes an atomizer assembly 2, which is disposed within the first housing 1. The atomizer assembly 2 includes a liquid suction element 21, a first control module 23, and an atomizer 22. The liquid suction element 21 is a generally elongated structure, with its lower end extending into the aromatherapy liquid, and its upper end connected to the atomizer 22. The liquid suction element 21 is configured to draw the aromatherapy liquid in the liquid storage container 3 into the atomizer 22. The atomizer 22 is configured to atomize the aromatherapy liquid that reaches the atomizer 22 into droplets. The first control module 23 is configured to control the atomization rate of the atomizer 22. Through the above-mentioned setting, the air flowing through the air duct enters the first shell 1 through the air inlet 121, and brings the droplet-shaped aromatherapy liquid dispersed throughout the first shell 1 to the outside of the aromatherapy device. At the same time, the atomization rate of the atomizer 22 is controlled by the first control module 23, so as to control the amount of aromatherapy liquid carried out to the outside of the aromatherapy device by the air, thereby controlling the amount of aromatherapy liquid entering the indoor space, and controlling the fragrance concentration in the indoor space to a more appropriate concentration range, so as to better meet the needs of users and enhance the user experience.

[0118] It should be noted that the shapes of the air inlet 121 and the air outlet 111 described above are merely exemplary. The air inlet 121 and the air outlet 111 can obviously be configured in other possible shapes, such as square, oval, or irregular. The shapes of the air inlet 121 and the air outlet 111 can be the same or different. Without departing from the principles of the present application, those skilled in the art can flexibly select the shapes of the air inlet 121 and the air outlet 111 according to the specific application scenario, as long as it does not affect the inflow and outflow of air.

[0119] It should be noted that the liquid suction component 21 can be, but is not limited to, a cotton swab, a fiber stick, a rattan stick, or the like, which can suck the aroma liquid from the liquid storage container 3 to the atomizer 22. The atomizer 22 can be, but is not limited to, a microporous atomizer sheet, a ceramic atomizer sheet, etc., which utilizes high-frequency oscillation of ions and high-frequency resonance of the atomizer sheet to break up the molecular structure of the aroma liquid and generate droplets. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific setting form of the liquid suction component 21 and the atomizer 22 according to the specific application scenario, as long as the aroma liquid can be attracted to the atomizer 22 through the liquid suction component 21 and the aroma liquid can be atomized into droplets through the atomizer 22.

[0120] It is understandable that the atomization efficiency of the atomizer 22 can be controlled by controlling the current flowing through the atomizer 22. For example, the current flowing through the atomizer 22 can be controlled by providing a current-controlled device such as a power field effect transistor, an NPN, a PNP transistor, or a silicon controlled rectifier (SCR) on the electrical wire connecting the atomizer 22 to the power supply. Obviously, the atomization efficiency of the atomizer 22 can also be controlled by controlling the voltage of the power supply for the atomizer 22. Without departing from the principles of the present application, those skilled in the art can flexibly select a specific method for controlling the atomization rate of the atomizer according to the specific application scenario, as long as the atomization rate of the atomizer can be accurately controlled.

[0121] like Figures 8 to 10 As shown and in accordance with Figure 9 In the illustrated orientation, the first housing 1 has a first chamber 13 and a second chamber 14 that are interconnected. The air inlet 121 is connected to the first chamber 13, and the air outlet 111 is connected to the second chamber 14. The atomizer 22 is disposed within the second chamber 14. Thus, external air enters the first chamber 13 through the air inlet 121, and then enters the second chamber 14, filling the second chamber 14. The aromatherapy liquid in the second chamber 14, which has been materialized into mist droplets by the atomizer, is then blown out of the air outlet 111. This allows the mist-shaped aromatherapy liquid in the second chamber 14 to be fully transported to the exterior of the aromatherapy device, improving the fragrance of the indoor space and increasing the utilization rate of the aromatherapy liquid. Obviously, the first housing 1 may also have only one chamber, or a greater number of chambers, such as three, four, or the like.

[0122] like Figures 8 to 10 As shown and in accordance with Figure 9In the illustrated configuration, the first control module 23 is the first computer board. Two positioning posts (not shown) are provided within the first chamber 13, each with a positioning hole (not shown). The first computer board is provided with two screw holes (not shown), located at opposite corners of the first computer board. Fasteners (such as bolts or screws) pass through the screw holes and connect with the positioning holes, thereby threading the first computer board into the first chamber 13. Obviously, the number of positioning posts and screw holes can also vary, for example, one, three, or four.

[0123] It should be noted that the first computer board can also be arranged in the first chamber 13 by bonding, clamping, etc. Obviously, the first control module 23 can also be set as a first circuit board, a first PCB board, or a first PC board, etc. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific form of the first control module 23 and its arrangement in the first housing 1 according to the specific application scenario, as long as the atomization rate of the atomizer can be controlled by the first control module 23.

[0124] like Figures 8 to 10 As shown and in accordance with Figure 9 In the orientation shown, a first partition 15 is provided within the first housing 1. The first partition 15 is arranged horizontally, thereby dividing the first housing 1 into a first chamber 13 located above and a second chamber 14 located below. A first through-hole 151 is provided on the first partition 15, and the first through-hole 151 is located near the left side of the first partition 15. The first chamber 13 is connected to the second chamber 14 through the first through-hole 151. The air inlet 121 is provided on the first bottom plate 12 of the first housing 1, near the right side of the first bottom plate 12, and the air outlet 111 is provided on the top plate of the first housing 1, near the right side of the top plate. In this way, the air entering the first chamber 13 through the air inlet 121 on the right side needs to flow through most areas of the first chamber 13, then enter the second chamber 14 through the first through hole 151 on the left side, and then flow through most areas of the second chamber 14, and then be discharged from the air outlet 111. In this way, through the buffering of the first chamber 13 and the second chamber 14, the air flow rate can be reduced and the air can fill the second chamber 14 as much as possible. The air located in various parts of the second chamber 14 can better carry the droplet-shaped aromatherapy liquid distributed in various parts of the second chamber 14 out of the first housing 1, so that the amount of aromatherapy liquid discharged from the aromatherapy device can be equivalent to the amount of aromatherapy liquid atomized by the atomizer 22, thereby improving the utilization efficiency of the aromatherapy liquid.

[0125] It should be noted that the air inlet 121 can also be located on the first bottom plate 12, near its left side. Obviously, the air outlet 111 can also be located at an upper side of the first housing 1, and the air inlet 121 can also be located at a lower side of the first housing 1. Those skilled in the art can flexibly select the specific locations of the air inlet 121 and the air outlet 111 based on the specific application scenario, as long as the air inlet 121 can be connected to the first chamber 13 and the air outlet 111 can be connected to the second chamber 14.

[0126] It should be noted that the first partition 15 can also be distributed along the vertical direction or in a direction having an angle with the vertical direction. Obviously, the first partition 15 may not be provided in the first shell 1, but two independent first chambers 13 and second chambers 14 are formed in the first shell 1, and then a connecting pipe is provided between the first chamber 13 and the second chamber 14, so that the first chamber 13 and the second chamber 14 are connected to each other through the connecting pipe. Without departing from the scope of the present application, those skilled in the art can flexibly select the formation method of the first chamber 13 and the second chamber 14 in the first shell 1 according to the specific application scenario, as long as the first chamber 13 and the second chamber 14 that are connected to each other can be formed in the first shell 1.

[0127] like Figures 8 to 10 As shown and in accordance with Figure 9 In the illustrated orientation, the underside of the first partition 15 is provided with a first flange 152, which extends downward from the first partition 15 and is arranged circumferentially around the first through-hole 151. This creates a barrier around the first through-hole 151, lengthening the air flow path within the first chamber 13 and prolonging its residence time there. This allows the air to fill the first chamber 13 as much as possible before entering the second chamber 14. This slows the air flow rate and prolongs its residence time within the second chamber 14, allowing it to fill the second chamber 14. This allows the droplets of aromatherapy liquid distributed throughout the second chamber 14 to be more efficiently removed from the first housing 1, improving the utilization efficiency of the aromatherapy liquid. Obviously, the underside of the first partition 15 does not need to be provided with the first flange 152.

[0128] like Figures 8 to 10 As shown and in accordance with Figure 9 In the orientation shown, a second partition 16 is provided in the second chamber 14. The second partition 16 is provided on the first partition 15, substantially along Figure 9The second partition plate 16 extends perpendicularly to the paper surface, and the second chamber 14 is divided into a first sub-chamber 141 on the left and a second sub-chamber 142 on the right, which are connected to each other. The first sub-chamber 141 is connected to the first chamber 13 through a first through-hole 151, and the air outlet 111 is connected to the second sub-chamber 142. The second partition plate 16 is also provided with a cylindrical structure 24 with an open right end. The left end of the cylindrical structure 24 is screwed to the right side of the second partition plate 16, near the central area. The atomizer 22 is provided at the bottom of the cylindrical structure 24, and the cylindrical wall of the cylindrical structure 24 extends in the left and right directions. In this way, the droplets of fragrance liquid atomized by the atomizer 22 are collected as much as possible within the cylindrical structure 24, then dispersed and moved rightward along the axial direction of the cylindrical structure 24. The air outlet 111 is located on the right side of the top plate of the first housing 1, that is, on the right side of the cylindrical structure 24. This effectively guides the droplets of fragrance liquid to the air outlet 111, facilitating their discharge. The air in the first chamber 13 then enters the first sub-chamber 141 through the first through-hole 151, filling the first sub-chamber 141 before entering the second sub-chamber 142 where the atomizer 22 resides. This further slows the air flow rate and allows the air to better fill the second sub-chamber 142. Since the droplets of fragrance liquid are primarily located within the second sub-chamber 142, near the air outlet 111, the air can effectively carry the droplets of fragrance liquid out of the first housing 1, further improving the utilization efficiency of the fragrance liquid. Obviously, the second partition plate 16 may not be provided in the second chamber 14. Obviously, the atomizing element 22 may also be provided on the right side of the second partition plate 16 by bonding, clamping or the like.

[0129] like Figure 9 and Figure 10 As shown and in accordance with Figure 9 In the illustrated orientation, the second partition 16 includes a mounting plate 161 and sub-plates 162 located on either side of the mounting plate 161. The height of the mounting plate 161 is approximately the same as the height of the second chamber 14, meaning that the upper end of the mounting plate 161 abuts the inner wall of the first housing 1. The atomizer 22 is mounted on the mounting plate 161. The height of the two sub-plates 162 is slightly lower than the height of the second chamber 14, meaning that a gap exists between the upper ends of the two sub-plates 162 and the inner wall of the first housing 1. The first sub-cavity 141 and the second sub-cavity 142 are connected to each other through this gap. This allows air entering the first sub-cavity 141 to pass through this gap and enter the second sub-cavity 142 in a direction nearly parallel to the inner wall of the first housing 1. This allows air to flow through more areas within the second sub-cavity 142, thereby better carrying the droplet-shaped aromatherapy liquid deposited in various locations within the second sub-cavity 142 out of the first housing 1.

[0130] It should be noted that the height of the mounting plate 161 and the two sub-plates 162 can also be lower than the height of the second chamber 14, that is, there is a gap between the upper ends of the mounting plate 161 and the two sub-plates 162 and the inner wall of the first housing 1. Obviously, the upper ends of the mounting plate 161 and the two sub-plates 162 can also abut the inner wall of the first housing 1. In this case, the first sub-cavity 141 and the second sub-cavity 142 can be connected by providing a plurality of holes of various shapes such as circular holes, rectangular holes, and irregular holes on the two sub-plates 162. The air in the first sub-cavity 141 can enter the second sub-cavity 142 through these holes of various shapes such as circular holes, rectangular holes, and irregular holes. Of course, the second partition 16 can also be an integrally arranged plate-like structure, and the atomizer 22 is arranged in the central area of ​​the plate-like structure. In this case, the first sub-cavity 141 and the second sub-cavity 142 can be connected by a gap between at least a portion of the upper end of the second partition 16 and the inner wall of the first housing 1, or by a circular hole, a rectangular hole, a special-shaped hole, or other possible holes arranged in an area of ​​the second partition 16 where the atomizer 22 is not arranged. Without departing from the scope of the present application, those skilled in the art can flexibly select the specific arrangement of the second partition 16 according to the specific application scenario, as long as the installation of the atomizer 22 and the mutual communication of the first sub-cavity 141 and the second sub-cavity 142 can be achieved.

[0131] It should be noted that the height of the second sub-cavity 142, the height of the mounting plate 161, and the height of the sub-plate 162 are based on the Figure 9 The dimensions of the second sub-cavity 142, the mounting plate 161, and the sub-plate 162 along the vertical direction are shown in FIG.

[0132] like Figures 9 to 11 As shown and in accordance with Figure 9 In the illustrated orientation, the first housing 1 has a second flange 17 extending inwardly at a position corresponding to the air outlet 111. This second flange 17 extends downward from the inner wall of the first housing 1 and is arranged circumferentially around the air outlet 111. This creates a barrier around the air outlet 111, further extending the air's residence time within the second sub-cavity 142. This barrier can better remove droplets of aromatherapy liquid deposited within the second chamber 14 from the first housing 1, improving its utilization efficiency. Obviously, the second flange 17 can be omitted from the inner side of the first housing 1. Obviously, the first housing 1 can also be omitted from the second flange 17.

[0133] like Figures 5 to 12As shown, the aromatherapy device also includes an air supply assembly 4, which includes a second housing 41 and a fan 42 disposed within the second housing 41. The second housing 41 includes a second base plate 412 and a second cover 411 that is inverted onto the second base plate 412. A second mounting post 4115 is disposed within the second cover 411, and a third mounting hole (not shown) is disposed on the second mounting post 4115. The second base plate 412 is provided with a fourth mounting hole (not shown). Fasteners (such as screws, bolts, etc.) pass through the fourth mounting hole and connect with the third mounting hole, thereby attaching the second base plate 412 to the second cover 411, forming the second housing 41. The side of the second cover 411 adjacent to the first housing 1 is recessed inward to form a recessed area 4111, and the first housing 1 is seated in this recessed area 4111. When installed, at least a portion of the first housing 1 is located within the recessed area 4111, thereby detachably attaching the first housing 1 and the second housing 41. The second housing 411 is provided with a second through-hole 4112. This second through-hole 4112 is roughly rectangular, and its shape and dimensions are roughly the same as those of the air inlet 121. When the first housing 1 and the second housing 41 are assembled, the second through-hole 4112 aligns with the air inlet 121, allowing the second housing 41 to communicate with the first housing 1 through the second through-hole 4112 and the air inlet 121. A fan 42 is positioned within the second housing 41 near the second through-hole 4112. This fan 42 is configured to blow the droplet-shaped aromatherapy liquid within the second chamber 14 out of the first housing 1. To ensure the smooth operation of the fan 42, the second base plate 412 is provided with ventilation holes 4121 at locations corresponding to the fan 42. This allows air outside the aromatherapy device to enter the second housing 41 through the ventilation holes 4121 and be blown out by the fan 42. Thus, when the fan 42 is operating, the air blown by the fan 42 directly enters the first chamber 13 through the second through-hole 4112 and the air inlet 121, then enters the second chamber 14 through the first through-hole 151, and blows the droplet-shaped aromatherapy liquid in the second chamber 14 out of the air outlet 111 to the outside of the first housing 1. Because the air blown by the fan 42 provides more air to the first housing 1 and accelerates the air flow within the first housing 1, the droplet-shaped aromatherapy liquid in the second chamber 14 can be better blown out, controlling the fragrance concentration in the indoor space within a more appropriate concentration range, and improving the user experience. Obviously, the fan 42 can also be positioned elsewhere within the second housing 41. Those skilled in the art can flexibly select the specific location of the fan 42 within the second housing 41 based on the specific application scenario, as long as the air blown by the fan 42 can blow the droplet-shaped aromatherapy liquid in the first housing 1 out of the first housing 1.

[0134] It should be noted that the shape and size of the second through hole 4112 and the air inlet 121 may also be different. Of course, only a portion of the second through hole 4112 may be aligned with the air inlet 121. Obviously, the second through hole 4112 may not be aligned with the air inlet 121, and the second through hole 4112 and the air inlet 121 may be connected to each other through a connecting pipe, thereby achieving mutual communication between the first housing 1 and the second housing 41. Those skilled in the art can flexibly select the shape and size of the second through hole 4112 according to the specific application scenario, as long as the air blown by the fan 42 can enter the first chamber 13 through the second through hole 4112 and the air inlet 121.

[0135] It should be noted that the fan 42 can be, but is not limited to, an axial flow fan, a centrifugal fan, or the like.

[0136] It is understandable that the first housing 1 and the second housing 41 can also be detachably connected by plugging, snapping, screwing, etc.

[0137] It should be noted that the aromatherapy device may also be provided without the fan 42, and may simply allow natural wind from outside to enter the first chamber 13 through the air inlet 121, thereby blowing the droplet-shaped aromatherapy liquid in the second chamber 14 out of the air outlet 111. However, in this case, the amount of air that can enter the first chamber 13 through the air inlet 121 is limited, and generally only a portion of the aromatherapy liquid in the second chamber 14 can be carried out.

[0138] It should be noted that, in order to realize all functions of the aroma control method of the present invention, the housing in the present invention includes a first housing 1 and a second housing 41 .

[0139] like Figures 7 to 12 As shown and in accordance with Figure 9In the orientation shown, the aromatherapy device also includes a second control module 43, which is a second computer board. The second computer board can be set in the second shell 41 by screwing, clamping, bonding, etc. A fourth through hole 4113 is provided on the recessed area 4111 of the second shell 41, and a fifth through hole 122 is provided on the first bottom plate 12 of the first shell 1. The aromatherapy device also includes an electrical connector 5, the lower end of the contact of the electrical connector 5 is electrically connected to the second control module 43, and the upper end of the contact passes through the fourth through hole 4113 and the fifth through hole 122 and is electrically connected to the first control module 23, thereby achieving an electrical connection between the second control module 43 and the first control module 23. The second control module 43 is configured to control the rotation speed of the fan 42 and transmit the control signal to the first control module 23 through the electrical connector 5, and then control the atomization rate of the atomizer 22 through the first control module 23. In this way, the second control module 43 can control the rotation speed of the fan 42 and the atomization rate of the atomizer 22, and can more accurately control the amount of aromatherapy liquid entering the indoor space, thereby better controlling the fragrance concentration in the indoor space within a more appropriate concentration range, thereby improving the user experience.

[0140] It should be noted that the second control module 43 can also be configured as a second circuit board, a second PCB board, or a second PC board, etc. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific form of the second control module 43 according to the specific application scenario, as long as the second control module 43 can control the rotation speed of the fan 42 and the atomization rate of the atomizer.

[0141] It should be noted that the electrical connector 5 may be, but is not limited to, a docking contact, a socket contact, etc. Without departing from the principles of the present application, those skilled in the art may flexibly select the specific configuration of the point connector according to the specific application scenario, as long as the electrical connection between the first control module 23 and the second control module 43 can be achieved through the electrical connector 5.

[0142] It should be noted that in order to realize all the functions of the aroma control method of the present invention, when the control unit is a controller specifically used to execute the aroma control method of the present application or a functional module or functional unit of a general controller, the control unit is the above-mentioned first control module 23 and / or second control module 43.

[0143] like Figures 8 to 11 As shown and in accordance with Figure 9In the orientation shown, a mounting seat 153 is provided on the lower side of the first partition 15. The mounting seat 153 is generally a cylindrical structure, and a first threaded section 1531 is provided on the inner wall of the cylindrical structure. The liquid storage container 3 is generally a cylindrical structure with an open top, and a second threaded section 31 is provided on the outer wall near the top. The first threaded section 1531 is matched with the second threaded section 31 to place the liquid storage container 3 on the mounting seat 153, and thus the liquid storage container 3 is placed on the first partition 15. When assembled, the lower end of the liquid absorbing member 21 is inserted into the liquid storage container 3 and immersed in the aromatherapy liquid. The upper end of the liquid absorbing member 21 passes through the first partition 15 and is connected to the atomizing member 22 located above the first partition 15. In this way, the aromatherapy liquid can be sucked into the atomizing member 22 through the liquid absorbing member 21. Obviously, the first partition 15 may be provided with a first perforation allowing the upper portion of the liquid storage container 3 to pass through, the top of the liquid storage container 3 is provided with a cover, the cover is provided with a second perforation allowing the liquid absorbing member 21 to pass through, the lower end of the liquid absorbing member 21 is inserted into the liquid storage container 3 through the second perforation and immersed in the aromatherapy liquid, and the upper end of the liquid absorbing member 21 is connected to the atomizer 22 located above the liquid storage container 3.

[0144] like Figure 5 、 Figure 7 、 Figures 9 to 12 As shown and in accordance with Figure 9 In the illustrated orientation, the first base plate 12 is provided with a third through-hole 18, the size and shape of which are roughly the same as those of the lower portion of the liquid storage container 3. The recessed area 4111 of the second housing 411 is recessed inward to form a receiving area 4114. This receiving area 4114 is generally cylindrical, with a cross-sectional dimension slightly larger than the radial dimension of the liquid storage container 3. When the first and second housings 1 and 41 are assembled, the upper end of the liquid storage container 3 is connected to the mounting seat 153, and the lower end passes through the third through-hole 18 and is positioned within the receiving area 4114. This arrangement ensures that the liquid storage container 3 is securely mounted within the first and second housings 1 and 41. To replace the liquid storage container 3 or add or replace the fragrance liquid, the first and second housings 1 and 41 are separated, and the liquid storage container 3 is unscrewed from the mounting seat 153, allowing for convenient replacement of the liquid storage container 3 or addition or replacement of the fragrance liquid.

[0145] It should be noted that the third through hole 18 may not be provided on the lower part of the first shell 1, and the accommodating position 4114 may not be provided on the second shell 41. The liquid storage container 3 does not pass through the first shell 1 but is only provided inside the first shell 1. In this case, the height of the first shell 1 must be high enough to completely accommodate the liquid storage container 3.

[0146] To sum up, in the preferred technical solution of the present invention, by providing the air inlet 121 and the air outlet 111 on the first shell 1, by extending at least the end of the liquid suction component away from the atomizer into the fragrance liquid, the atomizer and the liquid suction component are connected, and the atomizer can atomize the fragrance liquid into droplets, and the atomization rate of the atomizer 22 is controlled by the first control module 23, the amount of fragrance liquid carried out into the indoor space by the air can be controlled, thereby controlling the fragrance concentration in the indoor space within a more appropriate concentration range, better meeting the needs of users and improving user experience. By providing a first chamber 13 and a second chamber 14 that are interconnected within the first housing 1, dividing the first housing 1 into the interconnected first chamber 13 and the second chamber 14 by a first partition 15, dividing the second chamber 14 into a first sub-chamber 141 and a second sub-chamber 142 that are interconnected by a second partition 16, and providing a first flange 152 and a second flange 17, after air enters the first chamber 13 through the air inlet 121, it passes through the first sub-chamber 141 and the second sub-chamber 142 in sequence before being discharged from the air outlet 111. This can extend the flow path of air within the first housing 1 and the residence time of air within the first housing 1, thereby better filling the second sub-chamber 142 and better bringing the droplet-shaped aromatherapy liquid distributed throughout the second chamber 14 out of the first housing 1, so that the amount of aromatherapy liquid discharged from the aromatherapy device is equivalent to the amount of aromatherapy liquid atomized by the atomizer 22, thereby improving the utilization efficiency of the aromatherapy liquid. By detachably connecting the first housing 1 and the second housing 41 and communicating with each other, and by providing the fan 42 and the second control module 43, the droplet-shaped aromatherapy liquid in the second chamber 14 can be blown out faster and better, and the amount of aromatherapy liquid entering the indoor space can be more accurately controlled, thereby better controlling the fragrance concentration in the indoor space and improving the user experience.

[0147] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.
