Description

Technical Field

[0001] This application relates to the technical field of aromatherapy, and in particular, to an atomizing device and an atomizing device control method. Background Art

[0002] An aromatherapy device can decompose liquid aromatherapy essential oil into cold mist and disperse it into the surrounding air, making the air full of fragrance, improving air quality, and also being able to achieve a refreshing effect on people through the aroma. With the development of society, more and more people use aromatherapy devices as decorative items for interior design, and put forward higher requirements for the visual effects that aromatherapy devices can produce.

[0003] Currently, known aromatherapy devices usually set two fans. One fan is used to achieve the smoke landscape effect to enhance the visual effects that the aromatherapy device can produce, while the other fan is used to disperse the fragrance. However, such an aromatherapy device has a high cost, and the power consumption of the two fans when they are turned on increases, resulting in a short battery life of the aromatherapy device. Summary of the Invention

[0004] To solve the existing technical problems, this application provides an atomizing device and an atomizing device control method with good smoke landscape effect, strong fragrance dispersing ability, low cost, and longer battery life.

[0005] In a first aspect, an atomizing device is provided, including:

[0006] A fan, including an air outlet;

[0007] An air duct assembly, including a main air duct connected to the air outlet, a first air duct and a second air duct connected to the main air duct. The first air duct is communicated with an atomizing member for generating mist, and the second air duct is communicated with an atomizing chamber for aggregating mist;

[0008] An air duct switching assembly, including a switching member, and the switching member includes a closed state for closing the second air duct and an open state for opening the second air duct.

[0009] In a second aspect, an atomizing device control method is further provided, which is applied to the atomizing device described in the embodiments of this application, including:

[0010] Controlling the switching member of the air duct switching assembly to be in the closed state, controlling the atomizing member to be turned on, and controlling the fan to work in a first mode to blow the smoke generated by the atomizing member into the atomizing chamber;

[0011] After a first preset time period, controlling the switching member to be in the open state and controlling the fan to work in a second mode for a second preset time period;

[0012] Wherein, the working voltage of the second mode is greater than the working voltage of the first mode.

[0013] The atomizing device provided in the above embodiment includes a fan, a duct assembly and a duct switching assembly disposed corresponding to the air outlet of the fan. The duct assembly includes a first duct communicating with an atomizing member for generating mist and a second duct communicating with an atomizing chamber for aggregating mist. The second duct is closed or opened by a switching member. When the second duct is in a closed state, the air flow generated by the fan blows from the air outlet through the first duct and the atomizing channel in the atomizing member into the atomizing chamber and gradually aggregates therein. When the second duct is in an open state, the air flow generated by the fan blows from the air outlet through the second duct into the atomizing chamber, so that the air flow blown out from the second duct can form an air flow disturbance in the atomizing chamber to generate a landscape effect and accelerate the dispersion of the aggregated mist in the atomizing chamber to the outside of the atomizing chamber. Thus, only by one fan, combined with the arrangement of the duct assembly and the duct switching assembly, the atomizing device can form at least two working modes, produce a better visual effect, improve the fragrance dispersion performance, have a low cost, reduce the power consumption and have a stronger battery life.

[0014] In the above embodiment, the atomizing device control method and the corresponding atomizing device embodiment belong to the same concept, so they have the same technical effects as the atomizing device embodiment and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solution of the present invention will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the drawings. The described embodiments should not be regarded as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0025] In the following description, the expression "some embodiments" 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 they can be combined with each other without conflict.

[0026] In the following description, the terms "first", "second", and "third" only distinguish similar objects and do not represent specific sorting or quantity limitations for the objects. It can be understood that "first", "second", and "third" can be interchanged in a specific order or sequence when permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0027] Please refer to Figures 1 to 3 , which is a schematic structural diagram of an atomization device provided by an embodiment of the present application. The atomization device includes: a blower 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 communicating with an atomizing member 20 for generating mist, and the second air duct 33 communicating with an atomization chamber 520 for aggregating mist; an air duct switching assembly 40, including a switching member 41, the switching member 41 including a closed state for closing the second air duct 33 and an open state for opening the second air duct 33.

[0028] Among them, the blower 10, the air duct assembly 30 and the air duct switching assembly 40 together form an air outlet module in the atomization device. The design of the air duct assembly 30 includes a first air duct 32 respectively used for communicating with an atomization channel 21 in the atomizing member 20 of the atomization device, and a second air duct 33 communicating with an atomization chamber 520 in the atomization device for aggregating mist. The switching control of the opening or closing state of the second air duct 33 is performed by using the air duct switching assembly 40, so as to control the air volume generated by the blower 10 to flow to different target positions through the first air duct 32 and the second air duct 33 respectively, thereby obtaining the required spraying effect.

[0029] It should be noted that the first air duct 32 is in communication with the atomization channel 21 in the atomization member 20, and the second air duct 33 is in communication with the atomization chamber 520 for aggregating the mist, which means that when the air outlet module is installed in the atomization device, the positions of the first air duct 32 and the second air duct 33 are set such that the air volume flowing out through the first air duct 32 can correspondingly enter the atomization channel 21 in the atomization member 20, and the air volume flowing out through the second air duct 33 can correspondingly enter the atomization chamber 520.

[0030] The atomization member 20 refers to a component that can atomize water or essential oil to generate mist. For example, it can be a heating atomizer that atomizes water or essential oil by heating to generate mist, or an ultrasonic oscillator that atomizes water or essential oil by high-frequency vibration to generate mist, etc.

[0031] The atomization chamber 520 is usually formed in the atomization device and is usually set as a transparent chamber. The outlet of the atomization channel 21 of the atomization member 20 faces into the atomization chamber 520, and the atomization channel 21 is in communication with the atomization chamber 520, which can allow the atomization chamber 520 to aggregate the mist generated by the atomization member 20. The mist can flow or stay in the transparent atomization chamber 520 for a preset duration to form an expected landscape effect.

[0032] 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 installed in the atomization device, the end of the first air duct 32 away from the main air duct 31 is in communication with the atomization channel 21 of the atomization member 20, and the end of the second air duct 33 away from the main air duct 31 is in communication with the atomization chamber 520. In the air duct switching assembly 40, the switching member 41 can be a manually or automatically controlled switch, as long as it can achieve the switching control of closing or opening the second air duct 33.

[0033] 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 41. When the second air duct 33 is in the closed state, the air flow generated by the fan 10 flows from the air outlet 11 into the main air duct 31, 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 air flow 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 an 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, reduced power consumption, and stronger endurance.

[0034] In some embodiments, in the air duct switching assembly 40, the switch member 41 is configured as an automatically controlled switch, which is automatically controlled by the controller to realize the control of opening or closing the second air duct 33 in the air duct assembly 30, and correspondingly realize the switching control of different working modes of the atomizing device. The air duct switching assembly 40 also includes a controller, and the switch member 41 includes a driving member 42 controlled by the controller and a movable valve 43 connected to the driving member 42; the movable valve 43 includes a shielding portion 432; the driving member 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 member 41 is in a closed state, and when the movable valve 43 moves to expose the second air duct 33, the switch member 41 is in an open state. Among them, the switch component 41 uses the movable valve 43 to move horizontally under the action of the driving component 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 stroke distance for switching the second air duct 33 to be opened or closed, so that the space required 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 makes it easy to achieve precise switching control.

[0035] Optionally, a wind guiding hole 431 may also be provided on the movable valve 43. When the movable valve 43 moves to align the wind guiding hole 431 with the second air duct 33, the switch member 41 is in an open state. By providing the wind guiding hole 431 on the movable valve 43, the position where the wind guiding hole 431 is located can be set as the precise target position for controlling the opening of the second air duct 33, which is beneficial to achieving more precise control of the movable valve 43.

[0036] It should be noted that the switch member 41 of the air duct switching assembly 40 includes various 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 are in the form of a gear and rack cooperation, and the rotation number of the output shaft of the motor can be used to control the moving distance of the movable valve 43, so as to achieve more precise control.

[0037] In another example, please refer to 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 to drive the movable valve 43 to move to 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, and the telescopic movement distance of the valve core can be set to correspondingly control the moving distance of the movable valve 43, so that the wind guiding hole 431 of the movable valve 43 is aligned with the second air duct 33, or the shielding portion 432 is aligned with the second air duct 33, realizing the switching of the opening or closing of the second air duct 33. Optionally, the driving member 42 may further 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 power saving.

[0038] It should be noted that different embodiments of the air duct switching assembly 40 can be combined without mutual exclusion. For example, the elastic reset member 423 can also be applied to the embodiment where the driving member 42 includes a motor, and a gear is provided at the output end of the motor to mesh 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. The motor controls the rotation of the output shaft 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, and 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 fall within the protection scope of the present application and will not be elaborated here.

[0039] Optionally, the driving member 42 includes a two-position three-way valve. The two-position three-way valve includes a first position communicating with the first air duct 32 and a second position communicating with the second air duct 33. 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 to the first air duct 32, and a third valve port connected to the second air duct 33. The two-position three-way valve switches between the first position and the second position. When in the first position, the first valve port communicates with the second valve port, correspondingly realizing the communication between the main air duct 31 and the first air duct 32; when in the second position, the first valve port communicates with the third valve port, correspondingly realizing the communication between the main air duct 31 and the second air duct 33. During the operation of the atomizing device, when the controller controls the two-position three-way valve to be in the second position, the main air duct 31 communicates with the second channel through the first valve port and the third valve port. At this time, all the air volume generated by the blower 10 flows into the atomizing chamber 520 and will not be diverted to the atomizing channel 21 of the atomizing member 20. The air volume of the blower 10 can be fully used to blow the mist in the atomizing chamber 520 out of the chamber, forming a stronger mist output effect.

[0040] In some embodiments, please continue to refer to Figures 1 to 3 , the second air duct 33 includes a wind guiding 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 wind guiding section 331 and the mist blowing section 332. When the switch member 41 is in the open state, the air guiding hole 431 is aligned with the wind guiding section 331 and the mist blowing section 332. The second air duct 33 is set as a separated wind guiding section 331 and mist blowing section 332, and the movable valve 43 is arranged between the wind guiding section 331 and the mist blowing section 332. When the movable valve 43 moves to align the blocking portion 432 with the second air duct 33, the wind guiding section 331 and the mist blowing section 332 are separated. On the contrary, when the movable valve 43 moves to align the air guiding hole 431 with the second air duct 33, the wind guiding section 331 and the mist blowing section 332 are communicated. The wind guiding section 331 has a wind guiding section outlet 3310, and the mist blowing section 332 has a mist blowing section inlet 3320. The wind guiding section outlet 3310 and the mist blowing section inlet 3320 are oppositely arranged, and the air guiding hole 431 is correspondingly arranged with the wind guiding section outlet 3310 and the mist blowing section inlet 3320. Optionally, the shape and size of the air guiding hole 431 are the same as those of the wind guiding section outlet 3310 of the wind guiding section 331 facing the mist blowing section 332 and the mist blowing section inlet 3320 of the mist blowing section 332 facing the wind guiding section 331. When the switch member 41 is in the open state to open the second air duct 33, the air guiding hole 431 is directly opposite to the wind guiding section outlet 3310 and the mist blowing section inlet 3320, and the size of the air guiding hole 431 is the same as that of the wind guiding 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.

[0041] In some embodiments, the atomizing device further includes a housing 50, which includes a base 51 and an upper cover 52; the atomizing member 20 is detachably mounted on the base 51 or the upper cover 52; an atomizing chamber 520 is provided in the upper cover 52, and the atomizing member 20 is provided with a mist outlet communicating with the atomizing channel, and the mist outlet communicates with 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 uses a heating atomizer as the atomizing member 20. Specific examples of the heating atomizer may include, but are not limited to, an essential oil cartridge with a liquid storage cotton and a heating wire inside. 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 semi-transparent material to facilitate the formation of a smoke landscape effect visible from the outside of the atomizing device inside the atomizing chamber 520. Secondly, the fan 10, the air duct assembly 30 and the air duct switching assembly 40 are housed in the base 51, and the atomizing 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 position where the atomizing chamber 520 is located. After the air flow blown out from the air outlet 11 of the fan 10 flows into the main air duct 31, it is blown to the atomizing channel 21 of the atomizing member 20 by the first air duct 32, prompting the mist generated by the atomizing member 20 to flow toward and fill the atomizing chamber 520. When the second air duct 33 is opened, it is blown into the atomizing chamber 520 by the second air duct 33, generating a disturbance in the atomizing chamber 520 to form a better smoke landscape effect, and accelerating the blowing of the mist from the spray port to improve the fragrance diffusion performance.

[0042] Optionally, the housing 50 further includes a support portion 53 housed in the accommodation cavity formed by the base 51 and the upper cover 52 and located between the base 51 and the upper cover 52, and the atomizing chamber 520 is formed by enclosing the support portion 53 and the upper cover 52. Among them, a guiding member 531 protruding into the atomizing chamber 520 is provided on the support portion 53. The first air duct 32 also consists of two separated sections, and the section communicating with the atomizing channel 21 in the atomizing member 20 is a guiding section 321, which is formed in the guiding member 531. In the second air duct 33, the mist-blowing section 332 for communicating with the atomizing chamber 520 is also formed in the guiding member 531 and is arranged in parallel with the guiding section 321. Optionally, auxiliary fixing members 534 for fixing the fan 10, the air duct assembly 30 and the air duct switching assembly 40 to the base 51 are further provided on the lower surface of the support portion 53. In an optional example, the auxiliary fixing members 534 include a plurality of fixing columns.

[0043] On the other hand, in the embodiments of the present application, please refer to Figure 6 , and a method for controlling an atomizing device is further provided, which is applied to the atomizing device provided in the embodiments of the present application. The method for controlling an atomizing device includes:

[0044] S102. Control the switch of the air duct switching component to be in the closed state, control the atomizing component to be turned on, control the fan to operate in the first mode, and blow the smoke generated by the atomizing component into the atomizing chamber;

[0045] S103. After the first preset duration, control the switch to be in the open state, and control the fan to operate in the second mode for a second preset duration;

[0046] Wherein, the operating voltage of the second mode is greater than that of the first mode.

[0047] In the atomizing device, components such as the fan, switch, and atomizing component are all controlled by the 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.

[0048] The controller controls the switch to be in the closed state or the open state to correspondingly control the second air duct to be closed or opened. In this embodiment, before controlling the atomizing component to be turned on, the controller first controls the switch to switch to the closed state or maintain the current closed state, then controls the atomizing component to be turned on, and controls the fan to be turned on and operate in the first mode. Taking the atomizing component as a heating atomizer as an example, after the atomizing component is turned on, the heating element in the heating atomizer starts to heat the heating wire to generate smoke, and then the fan is started. The airflow generated by the fan operating in the first mode blows the smoke into the atomizing chamber.

[0049] After the fan operates in the first mode for the first preset duration, such as 5 seconds, the controller then controls the switch to switch to the open state to correspondingly open the second air duct, and controls the fan to operate in the second mode for the second preset duration, such as 13 seconds. The airflow generated by the fan operating in the second mode disturbs the smoke in the atomizing chamber to form a smoke landscape effect, and blows the smoke in the atomizing chamber out of the spray port of the atomizing device.

[0050] The airflow generated by the fan operating in the second mode is greater than the airflow generated by the fan operating in the first mode. The first mode is a small air volume mode, and the second mode is a large air volume mode. By using the fan to generate more airflow in the second mode to be diverted into the second air duct, the fragrance dispersing performance of the atomizing device is enhanced.

[0051] In the above embodiments, the air duct assembly includes a first air duct connected to the atomization channel of the atomization member and a second air duct connected to the atomization chamber for aggregating mist. During the operation of the atomization device, the controller controls the switch member to close or open the second air duct, so that the atomization device can work in different working modes accordingly. Different working modes of the atomization device respectively correspond to specific working timings of the switch member, the atomization member, and the fan. On the one hand, it is possible to minimize the fan startup time and meet the smoke landscape effect and fog dispersion performance on the premise of reducing the fan energy consumption. On the other hand, with the setting of one fan, it can meet the requirement of the atomization device to produce a better visual effect and improve the fragrance dispersion performance, with low cost, reduced power consumption, and stronger battery life of the atomization device.

[0052] In some embodiments, the atomization device includes a fan drive circuit, and the fan drive circuit includes a voltage regulation circuit and an auxiliary startup circuit connected between the voltage regulation circuit and the power supply terminal of the fan; in step S102, controlling the fan to work in the first mode includes:

[0053] After the atomization member is turned on for a third preset duration, a voltage regulation control signal is sent to the voltage regulation circuit, and then an on-work instruction is sent to the fan. The auxiliary startup circuit conducts 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 terminal.

[0054] Among them, before controlling the fan to turn on, the controller first controls the switch member to switch to the closed state or maintain the current closed state, then controls the atomization member to turn on for a third preset duration, such as 1.5 seconds, and then controls the fan to turn on and work in the first mode, which can make the atomization member produce fragrant mist before starting the fan to work, minimizing the fan energy consumption to the greatest extent.

[0055] Please refer to Figure 7, the voltage regulating circuit may include a voltage regulating chip U4. An exemplary implementation of the controller controlling the fan to operate in the first mode may be that the controller can send a first voltage regulating control signal to the voltage regulating chip U4, such as sending a first voltage regulating control signal to the enable terminal FAN Boost of the voltage regulating chip U4. The voltage regulating chip U4 steps down the operating voltage of the second mode, such as a 5V input voltage, to the operating 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 startup 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 then sends an enable work instruction to the fan control terminal. After the voltage regulating chip U4 steps down the input voltage to the operating voltage of the first mode of the fan FAN1, the field effect transistor Q4 conducts, that is, the auxiliary startup circuit 13 conducts, and the fan FAN1 quickly obtains the operating voltage of the first mode and starts, and operates in the first mode.

[0056] An exemplary implementation of the controller controlling the fan FAN1 to operate in the second mode may be that the controller sends a second voltage regulating control signal to the feedback terminal FB of the voltage regulating chip U4. The voltage regulating chip U4 boosts the operating voltage of the first mode, such as a 3.3V input voltage, to the operating voltage of the second mode, such as 5V, and outputs it to the power supply terminal of the fan FAN1 through the output terminal SW. At this time, the auxiliary startup circuit 13 is disconnected, and the voltage regulating chip U4 directly outputs the operating voltage of the second mode to the power supply terminal of the fan FAN1, and the fan FAN1 operates in the second mode.

[0057] In the above embodiment, in the atomizing device, through the setting of the voltage regulating circuit and the auxiliary startup circuit, the fan can operate at different operating voltages to generate different amounts of air volume at different time periods, that is, the fan can meet the requirements of the atomizing device for generating a smoke landscape effect and fragrance dispersion performance, and at the same time, the fan can minimize energy consumption and improve the battery life of the atomizing device.

[0058] In some embodiments, in step S102, before controlling the atomizing member to turn on, it further includes:

[0059] Controlling the fan to operate in the first mode for a fourth preset duration.

[0060] Optionally, in a spraying action, before the controller controls the heating wire of the atomizing member to start working, it first controls the fan to operate in the first mode for a fourth preset duration, such as 2S, which helps to exhaust the smoke in the atomizing member before starting the current spraying action.

[0061] In some other embodiments, taking the steps corresponding to execute in response to a spray operation instruction as one spray action, during one spray action or during the last spray action of consecutive multiple spray actions, after controlling the blower to work in the second mode for a second preset duration, it further includes:

[0062] Controlling the blower to work in the first mode for a fifth preset duration.

[0063] It should be noted that when the atomizing device is in use, it can be set that the control steps executed by the atomizing device based on receiving a spray operation instruction are one spray action. In this embodiment, steps S102 and S103 refer to the steps included in one spray action of the atomizing device.

[0064] Before the atomizing device ends the current spray operation, controlling the blower to work in the first mode for a fifth preset duration, such as 3.5S, helps to exhaust the smoke in the atomizing member completely and avoid the spray channel of the atomizing member being blocked by smoke condensation. Among them, ending the current spray operation can correspondingly refer to the completion of one spray action, or before the completion of consecutive multiple spray actions executed by the spray device based on consecutive multiple spray operation instructions. After the blower works in the second mode for the second preset duration, then controlling the blower to work in the first mode for defogging, the change in air volume is beneficial to improving the defogging effect.

[0065] In some other embodiments, before the atomizing device ends the current spray operation, controlling the blower to defog can also be to control the blower to pause and then turn on for a certain duration. Taking the steps corresponding to execute in response to a spray operation instruction as one spray action, during one spray action or during the last spray action of consecutive multiple spray actions, after controlling the blower to work in the second mode for a second preset duration, it further includes:

[0066] Controlling the blower to pause, and then controlling the blower to work in the first mode or the second mode for a fifth preset duration.

[0067] The pause duration of the blower can be different according to the actual usage situation. Before the atomizing device ends the current spray operation, first controlling the blower to pause, and then controlling the blower to work in the first mode or still in the second mode for a fifth preset duration for defogging, the change in air volume is beneficial to improving the defogging effect. Since the first mode and the second mode of the blower are controlled by different voltages, therefore, controlling the blower to pause and then start can avoid the problem that the continuous voltage regulation operation causes the blower to work unstably.

[0068] In some embodiments, please refer to Figure 8 , the atomizing device control method further includes:

[0069] S101. After the atomization device is turned on and before the spraying action is performed, obtain the ambient temperature, and accordingly control the fan to perform the corresponding preheating action according to the temperature range to which the ambient temperature belongs.

[0070] Among them, after the atomization device is turned on and before a spraying action is performed, the controller further includes obtaining the ambient temperature, and accordingly controlling the fan to perform the corresponding preheating action according to the temperature range to which the current ambient temperature belongs.

[0071] In this embodiment, the temperature ranges include 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 preheating action corresponding to the fan includes: controlling the fan to turn on and work for a first preset duration. When the ambient temperature is 0°C - 15°C, the preheating action corresponding to the fan includes: controlling the fan to turn on and work for a second preset duration; the first preset duration is greater than the second preset duration. When the ambient temperature is greater than 15°C, the preheating action corresponding to the fan is that the fan does not need to be turned on in advance.

[0072] Among them, during the process of the fan performing the preheating action, it usually works in the second mode to obtain a better preheating effect in a shorter time.

[0073] The atomization device and the atomization device control method provided by the embodiments of the present application at least have the following characteristics:

[0074] First, only a single fan is provided in the atomization device. By using the air duct assembly and the air duct switching assembly correspondingly arranged at the air outlet of the fan, the air flow generated by the fan during different periods can flow through the first air duct through the atomization channel of the atomization part to the atomization chamber, or directly flow to the atomization chamber through the second air duct, so that the atomization device forms two working modes of fog gathering and spraying, producing a better visual effect, improving the fragrance diffusion performance, with low cost, reduced power consumption, and stronger battery life.

[0075] Second, it is set that the fan can be turned on with different working voltages during different periods. The fan has a small air volume mode and a large air volume mode. The atomization device can work in the small air volume mode or the large air volume mode correspondingly in different working modes. On the basis of taking into account that only a single fan is provided in the atomization device to reduce costs and power consumption, it can meet the requirements of better visual effects and improved fragrance diffusion performance.

[0076] Third, in the atomization device, the controller controls the switching components in the fan, the atomization part, and the air duct switching assembly to form different specific working timings, which can minimize the fan startup time and meet the smoke landscape effect and fog diffusion performance of the atomization device on the premise of reducing the fan energy consumption.

[0077] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
