[0017] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0019] In the following description, the expression "some embodiments" is involved, which describes a subset of all possible embodiments. It should be noted that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

[0020] In the following description, the terms "first, second, and third" are merely used to distinguish similar objects and do not represent a specific order or quantity limitation for the objects. It can be understood that "first, second, and third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0021] See also Figures 1 to 3 , is a schematic diagram of the structure of an atomization device provided in an embodiment of the present application. The atomization device includes: a fan 10, including an air outlet 11; an air duct assembly 30, including a main air duct 31 connected to the air outlet 11, a first air duct 32 and a second air duct 33 connected to the main air duct 31, the first air duct 32 is connected to the atomization element 20 for generating mist, and the second air duct 33 is connected to the atomization chamber 520 for gathering mist; an air duct switching assembly 40, including a switch element 41, and the switch element 41 includes a closed state for closing the second air duct 33 and an open state for opening the second air duct 33.

[0022] Among them, the fan 10, the air duct assembly 30 and the air duct switching assembly 40 together form an air outlet module in the atomizing device. The air duct assembly 30 is designed to include a first air duct 32 for communicating with the atomizing channel 21 in the atomizing element 20 in the atomizing device, and a second air duct 33 for communicating with the atomizing chamber 520 for gathering mist in the atomizing device. The air duct switching assembly 40 is used to switch the opening or closing state of the second air duct 33 to control the air volume generated by the fan 10 to flow to different target positions through the first air duct 32 and the second air duct 33, respectively, so as to obtain the desired spray effect.

[0023] It should be noted that the first air duct 32 is connected to the atomizing channel 21 in the atomizing element 20, and the second air duct 33 is connected to the atomizing chamber 520 for gathering mist, which means that when the air outlet module is assembled in the atomizing device, the positions of the first air duct 32 and the second air duct 33 are set so that the air volume flowing out through the first air duct 32 can enter the atomizing channel 21 in the atomizing element 20 accordingly, and the air volume flowing out through the second air duct 33 can enter the atomizing chamber 520 accordingly.

[0024] The atomizer 20 refers to a component that can atomize water or essential oil to produce mist, such as a heating atomizer that atomizes water or essential oil to produce mist by heating, or an ultrasonic oscillator that atomizes water or essential oil to produce mist by high-frequency vibration.

[0025] The atomizing chamber 520 is usually formed in the atomizing device, and is usually set as a transparent chamber. The outlet of the atomizing channel 21 of the atomizing element 20 faces the atomizing chamber 520, and the atomizing channel 21 is connected to the atomizing chamber 520, so that the atomizing chamber 520 can gather the mist generated by the atomizing element 20. The mist can flow in the transparent atomizing chamber 520 or stay for a preset period of time to form the expected landscape effect.

[0026] In the air duct assembly 30, one end of the main air duct 31 is connected to the air outlet 11 of the fan 10, and the other end of the main air duct 31 is respectively connected to the first air duct 32 and the second air duct 33. When the air duct assembly 30 is arranged in the atomizing device, the end of the first air duct 32 away from the main air duct 31 is connected to the atomizing channel 21 of the atomizing element 20, and the end of the second air duct 33 away from the main air duct 31 is connected to the atomizing chamber 520. In the air duct switching assembly 40, the switch 41 can be a manually or automatically controlled switch, as long as it can realize the switching control of closing or opening the second air duct 33.

[0027] In the above embodiment, the air duct assembly 30 includes a first air duct 32 for communicating with the atomizing channel 21 of the atomizing element 20, and a second air duct 33 for communicating with the atomizing chamber 520 for gathering mist. The second air duct 33 is closed or opened by the switch element 41. When the second air duct 33 is in the closed state, the airflow generated by the fan 10 flows into the main air duct 31 from the air outlet 11, and then blows into the atomizing chamber 520 through the first air duct 32 and the atomizing channel 21 in the atomizing element 20, and gradually gathers in the atomizing chamber 520. When the second air duct 33 is in the open state, the airflow generated by the fan 10 flows from the air outlet 11 to the main air duct 31. After the air flows into the main air duct 31 through the air outlet 11, it is blown toward the atomizing chamber 520 through the second air duct 33. The airflow blown out of the second air duct 33 forms airflow disturbance in the atomizing chamber 520 to produce a landscape effect, and accelerates the mist gathered in the atomizing chamber 520 to form a spray and disperse outward. In this way, by only setting a fan 10 in the atomizing device, combined with the settings of the air duct component 30 and the air duct switching component 40, the atomizing device forms at least two working modes, and the airflow of the fan 10 is used to produce a better visual effect, improve the fragrance diffusion performance, and has low cost, can reduce power consumption, and has a stronger endurance.

[0028] In some embodiments, in the air duct switching assembly 40, the switch element 41 is set as an automatically controlled switch, and the opening or closing of the second air duct 33 in the air duct assembly 30 is controlled by the controller automatically, and the switching control of different working modes of the atomizing device is realized accordingly. The air duct switching assembly 40 also includes a controller, and the switch element 41 includes a driving element 42 controlled by the controller and a movable valve 43 connected to the driving element 42; the movable valve 43 includes a shielding portion 432; the driving element 42 controls the movement of the movable valve 43, and when the movable valve 43 moves to align the shielding portion 432 with the second air duct 33, that is, the shielding portion 432 covers the outlet of the second air duct 33, the shielding portion 432 cuts off the connection between the second air duct 33 and the atomizing chamber 520, the switch element 41 is in a closed state, and when the movable valve 43 moves to expose the second air duct 33, the switch element 41 is in an open state. Among them, the switch member 41 utilizes the movable valve 43 to move horizontally under the action of the driving member 42, so that the blocking portion 432 of the movable valve 43 can block the second air duct 33, thereby realizing the switching of the second air duct 33 to be opened or closed. The movable valve 43 has a short travel distance for switching the second air duct 33 to be opened or closed, so that the required occupied space is small. The movable valve 43 moves horizontally to align the blocking portion 432 with the second air duct 33, or staggered to expose the second air duct 33, which is easy to achieve precise switching control.

[0029] Optionally, an air guide hole 431 may be further provided on the movable valve 43. When the movable valve 43 moves to align the air guide hole 431 with the second air duct 33, the switch member 41 is in an open state. By providing the air guide hole 431 on the movable valve 43, the position of the air guide hole 431 may be set as a precise target position for controlling the opening of the second air duct 33, which is conducive to achieving more precise control of the movable valve 43.

[0030] It should be noted that the switch member 41 of the air duct switching assembly 40 includes multiple implementation forms. In one example, the driving member 42 includes a motor, a gear is provided at the output end of the motor, and a rack portion meshing with the gear is provided at one end of the movable valve 43 connected to the driving member 42. The driving member 42 and the movable valve 43 adopt a gear and rack matching form, and the number of rotations of the output shaft of the motor can be used to control the moving distance of the movable valve 43, so that more precise control can be achieved.

[0031] In another example, see Figure 4 and Figure 5 The driving member 42 includes a solenoid valve 421. The controller controls the movement of the valve core of the solenoid valve 421, driving the movable valve 43 to move and be in an open state or a closed state. The telescopic movement of the valve core of the solenoid valve 421 directly drives the movable valve 43 to move. The telescopic movement distance of the valve core can be set to control the movement distance of the movable valve 43 accordingly, so that the air guide hole 431 of the movable valve 43 is aligned with the second air duct 33, or the shielding part 432 is aligned with the second air duct 33, so as to realize the switching of the second air duct 33 to be opened or closed. Optionally, the driving member 42 may also include a transmission member connected between the valve core and the movable valve 43 and an elastic reset member 423 provided on the transmission member. When the solenoid valve 421 loses power, the elastic reset member 423 drives the movable valve 43 to move and reset from the current open state or closed state to achieve the effect of saving power.

[0032] It should be noted that different embodiments of the air duct switching assembly 40 can be combined without mutually excluding each other. For example, the elastic reset member 423 can also be applied to the driving member 42 including a motor. By setting a gear at the output end of the motor to engage with the rack portion provided on the movable valve 43, the elastic reset member 423 can be sleeved on the output shaft of the motor, and the motor controls the output shaft to rotate to drive the movable valve 43 to move to an open state or a closed state. At this time, the elastic reset member 423 is deformed. When the motor has no output, the elastic reset member 423 can be used to restore the deformation and drive the movable valve 43 to move and reset from the current open state or closed state. These obvious variant embodiments obtained under the technical teaching of the present application all belong to the protection scope of the present application and will not be elaborated here.

[0033] Optionally, the driving member 42 includes a two-position three-way valve, which includes a first position communicating with the first air duct 32 and a second position communicating with the second air duct 33, and the controller controls the two-position three-way valve to switch between the first position and the second position. The two-position three-way valve includes a first valve port communicating with the main air duct 31, a second valve port connected with the first air duct 32, and a third valve port connected with the second air duct 33, and the two-position three-way valve switches between the first position and the second position. When in the first position, the first valve port is communicated with the second valve port, and the communication between the main air duct 31 and the first air duct 32 is realized accordingly; when in the second position, the first valve port is communicated with the third valve port, and the communication between the main air duct 31 and the second air duct 33 is realized accordingly. During the operation of the atomization device, when the controller controls the two-position three-way valve to the second position, the main air duct 31 is connected to the second channel through the first valve port and the third valve port. At this time, the air volume generated by the fan 10 all flows into the atomization chamber 520, and will not be diverted to the atomization channel 21 of the atomization element 20. The air volume of the fan 10 can be fully used to blow the mist in the atomization chamber 520 out of the cavity, forming a stronger mist discharge effect.

[0034] In some embodiments, please refer to Figures 1 to 3 The second air duct 33 includes an air guide section 331 connected to the main air duct 31 and a mist blowing section 332 connected to the atomizing chamber 520; the movable valve 43 is located between the air guide section 331 and the mist blowing section 332, and when the switch 41 is in the open state, the air guide hole 431 is aligned with the air guide section 331 and the mist blowing section 332. The second air duct 33 is set to be a separated air guide section 331 and a mist blowing section 332, and the movable valve 43 is set between the air guide section 331 and the mist blowing section 332. When the movable valve 43 moves to the shielding portion 432 to align with the second air duct 33, the air guide section 331 and the mist blowing section 332 are separated. On the contrary, when the movable valve 43 moves to the air guide hole 431 to align with the second air duct 33, the air guide section 331 and the mist blowing section 332 are connected. The air guide section 331 has an air guide section outlet 3310, and the mist blowing section 332 has a mist blowing section inlet 3320. The air guide section outlet 3310 and the mist blowing section inlet 3320 are arranged opposite to each other, and the air guide hole 431 is arranged corresponding to the air guide section outlet 3310 and the mist blowing section inlet 3320. Optionally, the shape and size of the air guide hole 431 are the same as the shape and size of the air guide section outlet 3310 of the air guide section 331 facing the mist blowing section 332, and the shape and size of the mist blowing section inlet 3320 of the mist blowing section 332 facing the air guide section 331. When the switch member 41 is in the open state of opening the second air duct 33, the air guide hole 431 is directly opposite to the air guide section outlet 3310 and the mist blowing section inlet 3320, and the size of the air guide hole 431 is the same as the size of the air guide section outlet 3310 and the mist blowing section inlet 3320, which can avoid air leakage and ensure uniform air volume in the second air duct 33.

[0035] In some embodiments, the atomizing device further comprises a housing 50, the housing 50 comprises a base 51 and an upper cover 52; the atomizing element 20 is detachably mounted on the base 51 or the upper cover 52; an atomizing chamber 520 is provided in the upper cover 52, the atomizing element 20 is provided with a mist outlet connected to the atomizing channel, the mist outlet is connected to the atomizing chamber 520, and the fan 10, the air duct assembly 30 and the air duct switching assembly 40 are installed in the base 51. In this embodiment, the atomizing device adopts a heating atomizer as the atomizing element 20, and the specific example of the heating atomizer can be but is not limited to an essential oil fragrance bomb with liquid storage cotton and heating wire inside, and the housing 50 of the atomizing device is composed of a base 51 and an upper cover 52, which is convenient for assembly. The atomizing chamber 520 is formed in the upper cover 52, and the upper cover 52 can be made of a transparent or translucent material to facilitate the formation of a smoke landscape effect visible from the outside of the atomizing device in the atomizing chamber 520. Secondly, the fan 10, the air duct assembly 30 and the air duct switching assembly 40 are stored in the base 51, and the atomization chamber 520 is formed in the upper cover 52. The first air duct 32 and the second air duct 33 extend upward from the base 51 to the location of the atomization chamber 520. After the airflow blown out of the air outlet 11 of the fan 10 flows into the main air duct 31, it is blown toward the atomization channel 21 of the atomization element 20 by the first air duct 32, so that the mist generated by the atomization element 20 flows toward and fills the atomization chamber 520. When the second air duct 33 is opened, it is blown toward the atomization chamber 520 by the second air duct 33, generating disturbance in the atomization chamber 520 to form a better smoke landscape effect, and accelerate the mist to be blown out from the spray port, thereby improving the fragrance dispersion performance.

[0036] Optionally, the housing 50 also includes a support portion 53 that is received in a receiving cavity formed by the base 51 and the upper cover 52 and is located between the base 51 and the upper cover 52, and the atomizing cavity 520 is formed by the support portion 53 and the upper cover 52. Among them, the support portion 53 is provided with a guide member 531 that protrudes into the atomizing cavity 520, and the first air duct 32 is also composed of two separate sections, and the section that communicates with the atomizing channel 21 in the atomizing element 20 is the guide section 321, which is formed in the guide member 531, and in the second air duct 33, the blowing mist section 332 for communicating with the atomizing cavity 520 is also formed in the guide member 531, and is arranged in parallel with the guide section 321. Optionally, the lower surface of the support portion 53 is also provided with an auxiliary fixture 534 in which the fan 10, the air duct assembly 30 and the air duct switching assembly 40 are installed and fixed in the base 51. In an optional example, the auxiliary fixing member 534 includes a plurality of fixing columns.

[0037] On the other hand, please refer to Figure 6 , and also provides a method for controlling an atomizing device, which is applied to the atomizing device provided in the embodiment of the present application. The method for controlling an atomizing device includes: S102, controlling the switch element of the air duct switching assembly to be in a closed state, controlling the atomizing element to be turned on, and controlling the fan to operate in a first mode to blow the smoke generated by the atomizing element into the atomizing chamber; S103, after a first preset time, controlling the switch to be in an on state, and controlling the fan to operate in a second mode for a second preset time; Wherein, the operating voltage of the second mode is greater than the operating voltage of the first mode.

[0038] In the atomizing device, the fan, switch, atomizing element, etc. are all controlled by a controller. A computer program for implementing the atomizing device control method can be loaded into the controller, and the controller executes the corresponding atomizing device control method by running the computer program.

[0039] The controller controls the switch element to be in a closed state or an open state to control the second air duct to be closed or opened accordingly. In this embodiment, before controlling the atomizer to be turned on, the controller first controls the switch element to be switched to a closed state or to maintain the current closed state, then controls the atomizer to be turned on, and controls the fan to be turned on and to work in the first mode. Taking the atomizer as an example, after the atomizer is turned on, the heating element in the heating atomizer starts the heating wire to heat up to start generating smoke, and then starts the fan. The airflow generated by the fan working in the first mode blows the smoke into the atomizer chamber.

[0040] After the fan works in the first mode for a first preset time, such as 5 seconds, the controller controls the switch to switch to the on state to open the second air duct accordingly, and controls the fan to work in the second mode for a second preset time, such as 13 seconds. The airflow generated by the fan working in the second mode disturbs the smoke in the atomization chamber to form a smoke landscape effect, and blows the smoke in the atomization chamber out from the spray port of the atomization device.

[0041] The airflow generated by the fan in the second mode is greater than the airflow generated by the fan in the first mode. The first mode is a small air volume mode, and the second mode is a large air volume mode. The fan generates more airflow in the second mode to be diverted into the second air duct to enhance the fragrance diffusion performance of the atomization device.

[0042] In the above embodiment, the air duct assembly includes a first air duct connected to the atomization channel of the atomizer, and a second air duct connected to the atomization chamber for gathering mist. When the atomizer is working, the controller controls the switch to close or open the second air duct, so that the atomizer can work in different working modes accordingly. The different working modes of the atomizer correspond to different specific working sequences of the switch, atomizer and fan. On the one hand, the start-up time of the fan can be minimized, and the energy consumption of the fan can be reduced while meeting the smoke landscape effect and the mist dispersion performance. On the other hand, the setting of a fan can meet the needs of the atomizer to produce better visual effects and improve the fragrance dispersion performance. The cost is low, the power consumption can be reduced, and the endurance of the atomizer is stronger.

[0043] In some embodiments, the atomization device includes a fan drive circuit, and the fan drive circuit includes a voltage regulating circuit and an auxiliary starting circuit connected between the voltage regulating circuit and the power supply end of the fan; in step S102, controlling the fan to work in the first mode includes: After the atomizer is turned on for the third preset time, a voltage regulation control signal is sent to the voltage regulation circuit, and then a start-up instruction is sent to the fan. The auxiliary starting circuit is turned on after the voltage regulation circuit outputs the working voltage of the first mode, so that the voltage regulation circuit outputs the working voltage of the first mode to the power supply end.

[0044] Among them, before controlling the fan to turn on, the controller first controls the switch component to switch to the closed state or maintain the current closed state, and then controls the atomizer to turn on the third preset time, such as 1.5 seconds, and then controls the fan to turn on and work in the first mode, so that the atomizer can produce fragrant mist before starting the fan, thereby minimizing the energy consumption of the fan.

[0045] See also Figure 7, the voltage regulating circuit may include a voltage regulating chip U4. An exemplary implementation of the controller controlling the fan to work in the first mode may be that the controller may send a first voltage regulating control signal to the voltage regulating chip U4, such as sending the first voltage regulating control signal to the enable terminal FAN Boost of the voltage regulating chip U4, and the voltage regulating chip U4 steps down the working voltage of the second mode, such as the 5V input voltage, to the working voltage of the first mode, such as 3.3V, and outputs it to the power supply terminal of the fan FAN1 through the output terminal SW. The auxiliary starting circuit 13 is connected between the output terminal SW of the voltage regulating chip U4 and the power supply terminal of the fan FAN1, and includes a field effect transistor Q4. The drain D of the field effect transistor Q4 is connected to the electrical node between the output terminal SW of the voltage regulating chip U4 and the power supply terminal of the fan FAN1, the source S is connected to the electrode ground, and the gate G is connected to the fan control terminal. After the controller sends a first voltage regulating control signal to the voltage regulating chip U4, it sends a start-up instruction to the fan control terminal. After the voltage regulating chip U4 steps down the input voltage to the first mode working voltage of the fan FAN1, the field effect transistor Q4 is turned on, that is, the auxiliary starting circuit 13 is turned on, and the fan FAN1 quickly obtains the first mode working voltage and turns on, and works in the first mode.

[0046] An exemplary implementation method of the controller controlling the fan FAN1 to operate in the second mode may be that the controller sends a second voltage regulation control signal to the feedback terminal FB of the voltage regulating chip U4, and the voltage regulating chip U4 boosts the working voltage of the first mode, such as 3.3V input voltage, to the working voltage of the second mode, such as 5V, and outputs it to the power supply end of the fan FAN1 through the output terminal SW. At this time, the auxiliary starting circuit 13 is disconnected, and the voltage regulating chip U4 directly outputs the working voltage of the second mode to the power supply end of the fan FAN1, and the fan FAN1 operates in the second mode.

[0047] In the above embodiment, in the atomization device, by setting up the voltage regulating circuit and the auxiliary starting circuit, the fan can operate at different operating voltages to generate different air volumes in different time periods, so that the fan can meet the atomization device's requirements for producing smoke landscape effects and fragrance dispersion performance, and the fan can minimize energy consumption and improve the endurance of the atomization device.

[0048] In some embodiments, in step S102, before controlling the atomizing element to start, the method further includes: The fan is controlled to operate in the first mode for a fourth preset time period.

[0049] Optionally, in a spray action, before the controller controls the heating wire of the atomizer to start working, it first controls the fan to work in the first mode for a fourth preset time, such as 2S, which helps to exhaust the smoke in the atomizer before starting the current spray action.

[0050] In other embodiments, the step executed in response to a spray operation instruction is a spray action, and in a spray action or in the last spray action of a plurality of consecutive spray actions, after controlling the fan to operate in the second mode for a second preset time, the method further includes: The fan is controlled to operate in the first mode for a fifth preset time period.

[0051] It should be noted that when the atomizer is in use, the control steps executed by the atomizer after receiving a spray operation instruction can be set as one spray action. In this embodiment, steps S102 and S103 refer to the steps included in one spray action of the atomizer.

[0052] Before the atomizer ends the current spraying operation, the atomizer controls the fan to work in the first mode for the fifth preset time, such as 3.5S, which helps to exhaust the smoke in the atomizer and prevent smoke condensation from blocking the spray channel of the atomizer. Among them, ending the current spraying operation may correspond to the completion of a spraying action, or before the completion of multiple consecutive spraying actions executed by the spray device based on multiple consecutive spraying operation instructions. After the fan works in the second mode for the second preset time, the fan is controlled to work in the first mode for demisting. The change in air volume is conducive to improving the demisting effect.

[0053] In other embodiments, before the atomizing device ends the current spraying operation, controlling the fan to clear the mist may also be controlling the fan to pause and then restart for a certain period of time. The steps executed in response to a spraying operation instruction are one spraying action. In one spraying action or in the last spraying action of multiple consecutive spraying actions, the fan is controlled to work in the second mode for a second preset period of time, and further includes: The fan is controlled to pause, and then the fan is controlled to operate in the first mode or the second mode for a fifth preset time period.

[0054] The pause time of the fan can be different according to the actual use. Before the atomization device ends the current spraying work, it first controls the fan to pause, and then controls the fan to work in the first mode, or still in the second mode for the fifth preset time to perform mist removal. The change of air volume is beneficial to improve the mist removal effect. Since the first mode and the second mode of the fan are controlled by different voltages, controlling the fan to pause and then restart can avoid the problem of unstable operation of the fan caused by continuous voltage regulation operation.

[0055] In some embodiments, see Figure 8 , the atomization device control method further includes: S101, after the atomizing device is turned on and before the spraying action is performed, the ambient temperature is obtained, and according to the temperature range to which the ambient temperature belongs, the fan is controlled to perform a corresponding preheating action.

[0056] Among them, after the atomization device is turned on, before a spraying action is performed, the controller also includes obtaining the ambient temperature, and according to the temperature range to which the current ambient temperature belongs, correspondingly controlling the fan to perform a corresponding preheating action.

[0057] In this embodiment, the temperature range includes three temperature ranges: less than 0°C, 0°C-15°C, and greater than 15°C. When the ambient temperature is less than 0°C, the corresponding preheating action performed by the fan includes: controlling the fan to turn on and work for the first preset time. When the ambient temperature is 0°C-15°C, the corresponding preheating action performed by the fan includes: controlling the fan to turn on and work for the second preset time; the first preset time is greater than the second preset time. When the ambient temperature is greater than 15°C, the corresponding preheating action performed by the fan is that the fan does not need to be turned on in advance.

[0058] During the preheating process, the fan usually operates in the second mode so as to obtain a better preheating effect in a shorter time.

[0059] The atomization device and the atomization device control method provided in the embodiments of the present application have at least the following characteristics: First, only a single fan is arranged in the atomizing device, and by using the air duct assembly and the air duct switching assembly arranged corresponding to the air outlet of the fan, the airflow generated by the fan in different periods can flow to the atomizing chamber through the atomizing channel of the atomizing element through the first air duct, or directly flow to the atomizing chamber through the second air duct, so that the atomizing device forms two working modes of fog gathering and spraying, producing better visual effects, improving the fragrance dispersion performance, and having low cost, reduced power consumption, and stronger endurance.

[0060] Secondly, the fan can be turned on at different working voltages in different periods. The fan has a small air volume mode and a large air volume mode. The fan of the atomizing device can work in a small air volume mode or a large air volume mode accordingly in different working modes. On the basis of reducing costs and power consumption by setting only a single fan in the atomizing device, it can have better visual effects and improved fragrance diffusion performance.

[0061] Third, in the atomization device, the controller controls the switch components in the fan, atomization component, and air duct switching assembly to form different specific working sequences, which can minimize the fan start-up time and reduce the fan energy consumption while meeting the smoke landscape effect and fog dispersion performance of the atomization device.

[0062] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
