Description

Technical Field

[0001] This invention relates to the field of fan equipment technology, and in particular to a modular functional fan device and its control method, control device, and storage medium. Background Technology

[0002] Fans are widely used in homes, offices, and other places. To enrich their functionality, manufacturers have developed fan devices that can be equipped with additional functional modules. Users can choose to add various modules to the front of the fan's air outlet, such as humidification modules, aromatherapy modules, and UV sterilization modules. Taking a humidification module as an example, the humidification module atomizes water and outputs mist. The fan's air outlet outputs airflow, which carries the mist and diffuses it to various areas of the room. However, the range of mist diffusion is related to the airflow speed. Sometimes, users only need to control the fan. A low-speed airflow will cause the mist to accumulate only in the area closest to the fan, resulting in insignificant humidification. If the humidifier is used for an extended period, it may even cause localized dampness. Similarly, for aromatherapy and UV sterilization modules, insufficient airflow will cause the aromatherapy mist to accumulate in localized areas, leading to excessively high concentrations and potentially affecting the user's breathing. Furthermore, the UV sterilization module may produce trace amounts of ozone when exposed to airflow; if the airflow is insufficient, ozone may accumulate in localized areas.

[0003] However, in actual use, users may not easily consider how much airflow needs to be configured after activating the corresponding function module. At the same time, when a function module is installed, it means that a lower airflow setting cannot be used, making it inconvenient to use. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a modular functional fan device and its control method, control device, and storage medium, which are convenient to use and safe and reliable.

[0005] According to a first aspect of the present invention, a modular functional fan device includes: a housing having a cavity, the housing being provided with an air outlet communicating with the cavity; a load module including a fan assembly and a connector assembly, the fan assembly being disposed in the housing and located in the cavity, the fan assembly being able to guide airflow from the air outlet during operation; and a functional module including a base shell, functional components, and a flow restrictor, the base shell having a functional air duct, the base shell being provided with an air inlet and an air outlet respectively communicating with the functional air duct, the base shell being detachably disposed on the housing, and when the base shell is connected to the housing, the air inlet and the air outlet... The functional components and the current limiting device are connected in parallel to form at least a partial parallel unit. The fan assembly is detachably connected in series with the parallel unit through the connector assembly to form at least a partial drive branch. A power modulation module is capable of receiving control commands. The power modulation module modulates a drive current according to the control commands. The output terminal of the power modulation module is connected to the drive branch to output the drive current. The current limiting device is provided with a first current threshold. When the drive current is greater than the first current threshold, the resistance of the current limiting device increases or disconnects. When the drive current is less than the first current threshold, the resistance of the current limiting device is zero.

[0006] The modular fan device according to embodiments of the present invention has at least the following beneficial effects:

[0007] This invention relates to a modular fan device. Functional modules can be mounted on the housing. Parallel units of these functional modules can be connected to the drive circuit via connectors. When the user sets the fan assembly to rotate at a higher speed via control commands, it is understood that the power modulation module needs to output a larger drive current to supply the drive circuit to enable the fan assembly to rotate at a higher speed. At this time, the drive current exceeds a first current threshold, increasing or disconnecting the current-limiting element. In the parallel unit, the drive current passes through the functional components, activating them. These functional components then act on the airflow output from the air outlet. The airflow is then output to the outside. The higher airflow speed can transport the material formed by the functional components to a wider range of indoor areas, improving the effectiveness of the function. When the user sets the fan component to rotate at a lower airflow speed through control commands, the power modulation module needs to output a smaller drive current to supply the drive branch so that the fan component can rotate at a lower airflow speed. At this time, the drive current is less than the first current threshold, and the resistance of the current limiting component is zero, which is equivalent to bypassing the functional component. Thus, the functional component stops operating, and the material formed by the functional component is less likely to deposit in a local area. This design is convenient to use and safe and reliable.

[0008] According to some embodiments of the present invention, there are multiple functional modules, and one of the multiple functional modules can be selectively and detachably disposed in the housing, and the corresponding parallel unit is detachably connected to the fan assembly through the connector assembly; wherein, the functional components of different functional modules are different, and the first current threshold of the current limiting element is the same or different.

[0009] According to some embodiments of the present invention, the functional module is a humidification module, the functional component is an ultrasonic atomizing element, the humidification module further includes a liquid storage container, the liquid storage container has a liquid storage cavity and an atomizing port communicating with the liquid storage cavity, the base shell is also provided with a mixing port communicating with a functional air duct, the mixing port is located between the air inlet and the air outlet, the atomizing port and the mixing port are communicating, and the ultrasonic atomizing element is at least partially located in the liquid storage cavity so as to atomize the liquid in the liquid storage cavity and output it to the functional air duct; or, the functional module is an aromatherapy module, the functional component is a heating element, the aromatherapy module further includes a liquid storage container, the liquid storage container has a liquid storage cavity and an evaporation port communicating with the liquid storage cavity, the base shell is also provided with a mixing port communicating with a functional air duct, the mixing port is located between the air inlet and the air outlet, the evaporation port and the mixing port are communicating, and the heating element is capable of heating the liquid storage cavity.

[0010] According to some embodiments of the present invention, the modular functional fan device further includes an auxiliary resistor, which can be detachably connected in series with the parallel unit via the connector assembly when the parallel unit and the fan assembly are separated.

[0011] According to some embodiments of the present invention, the housing is provided with a plurality of electromagnetic components, and the base shell is provided with a plurality of magnetic blocks. The electromagnetic components include columnar magnets and coils wound around the outer periphery of the magnets. The magnets can attract the magnetic blocks one by one so that the base shell is connected to the housing. The output terminal of the power modulation module is connected to each of the coils through a switch module. The control terminal of the power modulation module is connected to the controlled terminal of the switch module. When the driving current is greater than a second current threshold, the power modulation module controls the switch module to conduct.

[0012] According to a second aspect of the present invention, a control method is applied to a modular fan device disclosed in any of the above embodiments. The modular fan device further includes a base and a steering drive and a detection element, both disposed on the base. A housing is rotatably disposed on the base. The steering drive is connected to the housing to drive the housing to rotate. The detection element is used to receive wireless signals from a remote control or a smartphone to determine the interaction direction based on the wireless signals. A power modulation module is connected to both the detection element and the steering drive. The power modulation module executes the control method. The control method includes: acquiring a control command, the control command including at least one instruction for guiding... The target airflow value for the operation of the fan assembly is used to derive the corresponding target current value. When the target current value is less than the first current threshold and the control command also includes a setting command representing the function required to be implemented by the functional module, the deflection angle is calculated based on the preset control current value and the target current value in the airflow intensity prediction model, wherein the control current value is greater than the first current threshold. The fan assembly enters the oblique airflow mode. In the oblique airflow mode, the housing is rotated by the steering drive component according to the interaction direction and the deflection angle, so that the angle between the air outlet direction and the interaction direction is the deflection angle. The power modulation module outputs the drive current, and the drive current approaches the control current value.

[0013] The control method according to embodiments of the present invention has at least the following beneficial effects:

[0014] The control method of this invention, when the user inputs a small target airflow value and simultaneously sets the function of the required functional module to be activated, calculates the deflection angle based on the target current value corresponding to the target airflow value and the control current value corresponding to the actual airflow value used for control. In the oblique airflow mode, the interaction direction is obtained, which can be considered as the direction of the user relative to the fan device. The housing is rotated so that the angle between the air outlet's airflow direction and the interaction direction is the deflection angle. Then, the fan assembly is controlled to output air with a control current value greater than the first current threshold. At this time, the actual airflow velocity at the air outlet is relatively large, but it does not blow directly on the user. Instead, it blows towards the user from the side. The airflow velocity can meet the user's set target airflow value requirement. The large airflow velocity at the air outlet can also deliver the material formed by the functional component to a wider range of the room. This design is convenient to use and safe and reliable.

[0015] According to some embodiments of the present invention, in the calculation of the deflection angle based on the wind flow intensity prediction model according to the preset control current value and the current target value, the wind flow intensity prediction model is as follows:

[0016] ,

[0017] in, For the target current value, To adjust the current value, This is the deflection angle.

[0018] According to some embodiments of the present invention, the control method further includes: switching between a slanted air guide mode and a direct air blowing mode at a preset time interval, wherein, in the direct air blowing mode, the housing is rotated by a steering drive component to make the air outlet direction and the interaction direction the same, the power modulation module outputs a drive current, and the drive current approaches the target current value.

[0019] According to a third aspect of the present invention, the control device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the control method disclosed in the above embodiments.

[0020] According to a fourth aspect of the present invention, a computer-readable storage medium stores a computer program, characterized in that, when the computer program is executed by a processor, it implements the control method disclosed in the above embodiments.

[0035] like Figures 1 to 5As shown, a modular fan device according to a first aspect embodiment of the present invention includes a housing 120, a load module 130, a functional module 200, and a power modulation module 300. The housing 120 has a cavity 121, and the housing 120 is provided with an air outlet 122 communicating with the cavity 121. The load module 130 includes a fan assembly 131 and a connector assembly. The fan assembly 131 is disposed in the housing 120 and located in the cavity 121. When the fan assembly 131 is running, it can guide airflow to be output from the air outlet 122. The functional module 200 includes a base shell 210, a functional component 220, and a current limiting element 230. The base shell 210 has a functional air duct 211. The base shell 210 is provided with an air inlet 212 and an air outlet 213 respectively communicating with the functional air duct 211. The base shell 210 is detachably provided with When the base shell 210 is placed on the housing 120 and connected to the housing 120, the air inlet 212 and the air outlet 122 are connected. The functional component 220 and the current limiting component 230 are connected in parallel to form at least a partial parallel unit. The fan assembly 131 is detachably connected in series with the parallel unit through the connector assembly to form at least a partial drive branch. The power modulation module 300 can receive control commands. The power modulation module 300 modulates the drive current according to the control commands. The output terminal of the power modulation module 300 is connected to the drive branch to output the drive current. The current limiting component 230 is provided with a first current threshold. When the drive current is greater than the first current threshold, the resistance of the current limiting component 230 increases or disconnects. When the drive current is less than the first current threshold, the resistance of the current limiting component 230 is zero.

[0036] The modular fan device may also include a base 110, which can be placed vertically on the ground or table, or installed on a wall or ceiling. The base 110 is provided with a steering drive component, which may be a rotary motor, a rotary cylinder, etc. The steering drive rod is connected to the housing 120 so as to drive the housing 120 to rotate and change the air outlet direction.

[0037] The power modulation module 300 includes a voltage regulation module 310, a control module 320, and a drive module 330. The voltage regulation module 310 can employ a switching power supply chip and its auxiliary circuitry. The voltage regulation module 310 includes a first rectifier unit, a semiconductor switching transistor, a transformer unit, a second rectifier unit, a voltage detection unit, and a current detection unit 311. Both the first and second rectifier units can employ a full-wave rectifier circuit or a half-wave rectifier circuit composed of diodes. The transformer unit includes mutually coupled primary windings, secondary windings, and a detection winding. The input terminal of the rectifier unit is used to connect with… The power supply is connected, the output terminal of the rectifier unit is connected to the first end of the primary winding, the tail end of the primary winding is connected to the input terminal of the first switching transistor, the output terminal of the switching transistor is grounded, the secondary winding is connected to the input terminal of the second rectifier unit, the voltage detection unit is connected to the detection winding to obtain the output voltage, and the control module 320 may include a processor such as an MCU or CPU and its auxiliary circuits as a control chip for the switching power supply. The control module 320 controls the switching of the first switching transistor according to the output voltage fed back by the voltage detection unit, so that the output terminal of the second rectifier unit outputs a relatively constant drive power supply.

[0038] like Figure 3 As shown, the drive module 330 includes a second switch Q1, and the connector assembly includes a first male connector 132 and a second female connector 133. The output terminal of the second rectifier unit is connected to the first male connector 132, and the input terminal of the second switch Q1 is connected to the second female connector 133. The current detection unit 311 may include resistors R4 and R5. The output terminal of the second switch Q1 is connected to the first end of resistor R4 and the first end of resistor R5, respectively. The tail end of resistor R4 is connected to the control module 320 to provide feedback on the drive current sampled by the current detection unit 311. The tail end of resistor R5 is grounded. The module 200 has a first female connector 240 at the beginning of the parallel unit and a second male connector 250 at the end of the parallel unit. The first male connector 132 and the first female connector 240 can be electrically connected by plugging and unplugging. Similarly, the second male connector 250 and the second female connector 133 can be electrically connected by plugging and unplugging so that the fan assembly 131 can be detachably connected in series with the parallel unit through the connector assembly to form at least part of the drive branch. The control module 320 can output a PWM signal according to the feedback drive current to control the on and off of the second switch to modulate the magnitude of the drive current.

[0039] In some embodiments of the present invention, the current limiting element 230 may be a resettable fuse, a current limiting chip (such as ADM1270, PW1605, PW1558, etc.), a thyristor, etc. Specifically, the parallel unit may also include a diode D4, which is connected in series with the functional component 220. The negative terminal of the diode D4 is connected to the first end of the functional component 220, and the positive terminal of the diode D4 is connected to the current limiting element 230.

[0040] The modular fan device of this invention can have a functional module 200 mounted on the housing 120. The parallel units of the functional module 200 can be connected to the drive branch via connector components. When the user sets the fan assembly 131 to rotate at a higher wind speed via control commands, it is understood that the power modulation module 300 needs to output a larger drive current to supply the drive branch to make the fan assembly 131 rotate at a higher wind speed. At this time, the drive current exceeds the first current threshold, increasing the resistance of the current limiting component 230 or disconnecting it. In the parallel unit, the drive current will pass through the functional component 220, causing the functional component 220 to start. The functional component 220 can then act on the output of the air outlet 122. The airflow is then output to the outside. The higher airflow speed can transport the material formed by the function component 220 to a wider range of indoor areas, improving the function's effectiveness. When the user sets the fan component 131 to rotate at a lower airflow speed via control commands, the power modulation module 300 needs to output a smaller drive current to supply the drive branch so that the fan component 131 rotates at a lower airflow speed. At this time, the drive current is less than the first current threshold, and the resistance of the current limiting component 230 is zero, which is equivalent to bypassing the function component 220. Thus, the function component 220 stops operating, and the material formed by the function component 220 is less likely to deposit in a local area. This design is convenient to use and safe and reliable.

[0041] In some embodiments of the present invention, there are multiple functional modules 200, and one of the multiple functional modules 200 can be selectively and detachably disposed in the housing 120, and the corresponding parallel unit is detachably connected to the fan assembly 131 through the connector assembly; wherein, the functional components 220 of different functional modules 200 are different, and the first current threshold of the current limiting element 230 is the same or different.

[0042] It is understandable that there can be multiple functional modules 200, and the functional components 220 within different functional modules 200 are different to achieve different functions. Since the functional components 220 are different, the required airflow and air speed provided by the fan component 131 are also different. For example, when the functional module 200 is a humidification module, the required airflow and air speed are relatively high, while when the functional module 200 is an aromatherapy module, the required airflow and air speed can be relatively low. Therefore, the first current threshold of the current limiting component 230 in different functional modules 200 can be set differently. When the driving current does not reach the first current threshold of the functional module 200, the current limiting component 230 short-circuits and bypasses the functional component 220, causing the functional component 220 to stop operating. This method is compatible with various functional components 220 and is convenient and simple to use.

[0043] Specifically, such as Figure 1As shown, the functional module 200 can be a humidification module, the functional component 220 is an ultrasonic atomizing element, the humidification module also includes a liquid storage container 260, the liquid storage container 260 has a liquid storage cavity and an atomizing port communicating with the liquid storage cavity, the base shell 210 is also provided with a mixing port communicating with the functional air duct 211, the mixing port is located between the air inlet 212 and the air outlet 213, the atomizing port and the mixing port are connected, and the ultrasonic atomizing element is at least partially located in the liquid storage cavity so as to atomize the liquid in the liquid storage cavity and output it to the functional air duct 211;

[0044] Users can add liquid into the storage chamber. The liquid can be water. The ultrasonic atomizing component can include an ultrasonic atomizing plate and a liquid-guiding rod made of materials such as cotton. The ultrasonic atomizing plate can be positioned near the atomization port. The head end of the liquid-guiding rod contacts the back of the ultrasonic atomizing plate, and the tail end of the liquid-guiding rod extends into the storage chamber. The liquid is conducted to the ultrasonic atomizing plate, which vibrates to atomize the liquid and output it to the functional air duct 211, where it is carried by the airflow to the outside.

[0045] Alternatively, the functional module 200 can be an aromatherapy module, the functional component 220 is a heating element, and the aromatherapy module also includes a liquid storage container 260. The liquid storage container 260 has a liquid storage cavity and an evaporation port communicating with the liquid storage cavity. The base shell 210 is also provided with a mixing port communicating with the functional air duct 211. The mixing port is located between the air inlet 212 and the air outlet 213. The evaporation port and the mixing port are connected. The heating element can heat the liquid storage cavity. The heating element can be a semiconductor heating element or a resistance wire, etc., and can be arranged around the outer peripheral wall of the liquid storage container 260. Aromatherapy essential oils or perfume balms can be added to the liquid storage container 260. It is understood that the heating element only maintains a weak heat to keep the liquid storage container 260 at a reasonable temperature value to improve the evaporation rate of aromatherapy essential oils or perfume balms. The evaporated mist can be output to the functional air duct 211 and carried out to the outside by the airflow.

[0046] The functional module 200 may also include an ultraviolet sterilization module, a mosquito repellent module, etc.

[0047] In some embodiments of the present invention, the modular fan device further includes an auxiliary resistor (not shown in the figure) that can be detachably connected in series with the parallel unit via the connector assembly when the parallel unit and the fan assembly 131 are separated.

[0048] After the user removes the functional module 200 from the housing 120, in order to ensure that the fan device can operate normally, an auxiliary resistor can be connected between the first male connector 132 and the second female connector 133. The first end of the auxiliary resistor is also provided with a first female connector 240, and the tail end of the auxiliary resistor is also provided with a second male connector 250. The auxiliary resistor can be made of conventional resistors or wires. After the auxiliary resistor is connected, the drive branch is turned on, and the fan assembly 131 operates normally.

[0049] In some embodiments of the present invention, such as Figure 1 As shown, the housing 120 is provided with a plurality of electromagnetic components 123, and the base shell 210 is provided with a plurality of magnetic blocks 214. The electromagnetic component 123 includes a columnar magnet and a coil wound around the outer periphery of the magnet. The magnet can attract the magnetic blocks 214 one by one so that the base shell 210 is connected to the housing 120. The output terminal of the power modulation module 300 is connected to each of the coils through the switch module 350. The control terminal of the power modulation module 300 is connected to the controlled terminal of the switch module 350. When the driving current is greater than the second current threshold, the power modulation module 300 controls the switch module 350 to conduct.

[0050] Understandably, multiple electromagnetic components 123 can be arranged around the air outlet 122 on the housing 120. Similarly, magnetic blocks 214 can be arranged around the air inlet 212 on the base housing 210. When installing the functional module 200 on the fan device, the user can bring the base housing 210 close to the housing 120, and the magnets can attract the magnetic blocks 214 one by one, thus achieving simple installation. At lower wind speeds, the vibration of the fan assembly 131 is smaller, the airflow is gentler, and the magnetic force is sufficient, so the functional module 200 is not easy to fall off. If a larger driving current is applied to the fan assembly 131 to output a higher wind speed airflow, in order to ensure the stability of the functional module 200, the power modulation module 300 can output current to the coil. The magnetism generated by the coil is in the same direction as the magnet, which can increase the attraction of the magnetic blocks 214. When the driving current is smaller, there is no need to apply current to the coil, saving energy.

[0051] Specifically, the second current threshold can be set by the manufacturer or the user according to the actual situation. The second current threshold can be equal to the first current threshold or they can be different. The switch module 350 can be a semiconductor switch, relay, etc. The control module 320 is connected to the controlled terminal of the switch module 350 to control the switching module 350 to turn on or off.

[0052] The control method according to the second aspect of the present invention, such as Figure 4 , 5As shown, the modular fan device disclosed in any of the above embodiments further includes a detector 340 disposed on the base 110, a housing 120 rotatably disposed on the base 110, a steering drive connected to the housing 120 to drive the housing 120 to rotate, the detector 340 being used to receive wireless signals from a remote control or smartphone to determine the interaction direction based on the wireless signals, and a power modulation module 300 being connected to the detector 340 and the steering drive respectively, the power modulation module 300 executing the control method, the control method including:

[0053] S410. Obtain control instructions, the control instructions including at least a target airflow value for guiding the operation of the fan assembly 131, and derive the corresponding target current value based on the target airflow value.

[0054] S420. When the target current value is less than the first current threshold and the control command also includes a setting command that represents the function of the functional module 200 to be implemented, the deflection angle is calculated based on the wind flow intensity prediction model according to the preset control current value and the target current value, wherein the control current value is greater than the first current threshold.

[0055] S430, Enter the oblique air guide mode. In the oblique air guide mode, the housing 120 is controlled to rotate by the steering drive component according to the interaction direction and deflection angle, so that the angle between the air outlet 213 and the interaction direction is the deflection angle. The power modulation module 300 outputs the drive current, and the drive current approaches the control current value.

[0056] Understandably, users can send wireless control commands via mobile phone or remote control. The detector 340 can be a wireless receiver chip, radar receiver chip, or ultrasonic receiver chip, etc. The detector 340 can receive control commands and output them to the control module 320. The control module 320 analyzes the direction of the mobile phone or remote control based on the direction of the wireless signal transmission, and thus determines the interaction direction. Generally speaking, the user's mobile phone or remote control is usually placed near the user's location. Therefore, the interaction direction is the user's direction relative to the fan device.

[0057] The control command can set the airflow intensity, which can be a specific value, i.e., the airflow target value, or a strong, medium, weak, etc. The corresponding airflow target value is then obtained based on the level. The airflow target value can be understood as the airflow speed output by the fan assembly 131 in the interaction direction. The driving current is applied to the fan assembly 131. The larger the driving current, the greater the rotation speed of the fan assembly 131, and the greater the corresponding airflow speed. Therefore, the current and airflow speed are related, and the corresponding current target value can be obtained based on the airflow target value.

[0058] The control method of this invention, when the user inputs a small target airflow value and simultaneously sets the function module 200 to be activated, calculates the deflection angle based on the target current value corresponding to the target airflow value and the control current value corresponding to the actual airflow value used for control. In the oblique airflow mode, the interaction direction is obtained, which can be considered as the direction of the user relative to the fan device. The housing 120 is rotated so that the angle between the air outlet 213's airflow direction and the interaction direction is the deflection angle. Then, the fan assembly 131 is controlled to output air with a control current value greater than the first current threshold. At this time, the actual airflow velocity of the air outlet 213 is relatively large, but it does not blow directly on the user. Instead, it blows towards the user from the side. The airflow velocity can meet the user's set target airflow value requirement. The relatively large airflow velocity of the air outlet 213 can also deliver the material formed by the function component 220 to a wider range of the room. This design is convenient to use and safe and reliable.

[0059] Additionally, it is understandable that the regulating current value can be preset by the manufacturer or the user. When the regulating current value is greater than the first current threshold, the driving current approaches the regulating current value applied to the fan assembly 131, and the airflow output by the fan assembly 131 will also be greater than the target airflow value required by the user. However, because the air outlet direction and the interaction direction of the air outlet 213 are tilted relative to each other, such as... Figure 5 As shown, the airflow experienced by the user is an airflow that is inclined to the air outlet 213 in the direction of airflow. The airflow is weakened. Calculated in terms of air volume component, the housing 120 is rotated to a suitable deflection angle so that the airflow component roughly meets the user's needs.

[0060] In some embodiments of the present invention, such as Figure 5 As shown, in the calculation of the deflection angle based on the preset control current value and current target value using the airflow intensity prediction model, the airflow intensity prediction model is as follows:

[0061] ,

[0062] in, For the target current value, To adjust the current value, This is the deflection angle.

[0063] In some embodiments of the present invention, the control method further includes:

[0064] The system switches between oblique airflow mode and direct airflow mode at preset time intervals. In direct airflow mode, the housing is rotated by a steering drive to make the airflow direction of the outlet the same as the interaction direction. The power modulation module outputs drive current, and the drive current approaches the target current value.

[0065] The preset time interval can be set by the manufacturer or the user. In the direct airflow mode, the functional components stop operating because the drive current is reduced to the current target value, but it can still provide the user with direct airflow to meet the user's needs.

[0066] Understandably, when the target current value calculated from the user's initial airflow target value is greater than the first current threshold, the control module does not need to control the housing deflection. It can directly apply a drive current close to the current target value to the fan assembly, the air outlet faces the user to output airflow, and the functional components start running.
