Description

Technical Field

[0001] The present invention relates to the technical field of fans, and more particularly to a swaying fan. Background Art

[0002] A fan is a device that drives the fan blades to rotate through a motor to push the air to circulate and form wind, and it is a commonly used household appliance for people to cool down in summer;

[0003] Traditional fans include ceiling fans, floor fans, etc. With the popularization of home design, ceilings are often installed during home design to increase beauty. Now traditional ceiling fans are rarely used. The basic structure of a floor fan generally includes: a base, a vertical rod, and a fan head. The fan blades in the fan head rotate to push the air to flow and form wind; and now bladeless fans have emerged on the market. Bladeless fans are highly safe and more beautiful in shape, and are deeply loved by consumers.

[0004] However, most of the air inlet and outlet structures of the existing bladeless fans on the market are in the front-back or up-down modes. When turning is required, air duct guidance needs to be done, and the structure is often complex and the fan load is increased. Moreover, there are various drawbacks when the existing fans blow air at people for a long time, and the experience is not comfortable. There will be headaches and dizziness after blowing air for a long time.

[0005] Finally, the shaping methods of market fan products are gradually solidified and assimilated, which is not conducive to the development of product diversity.

[0006] Therefore, the applicant proposes a fan that simulates manual fanning and can switch the wind direction at a large angle. Summary of the Invention

[0007] In view of this, the present invention provides a swaying fan.

[0008] To achieve the above object, the present invention adopts the following technical scheme: A swaying fan, comprising: a body, inside which a fan component is installed, and the fan component operates to form an air flow;

[0009] At least two groups of swing leaves, installed on the body, and the swing leaves swing independently along parallel axes; after the air flow blows out from the fan component, it can flow along the surfaces of the respective swing leaves in sequence, and the swing leaves swing to fan the air to adjust the blowing angle of the air flow.

[0010] The above-mentioned swaying fan simulates the way of manual fanning. Through the back-and-forth swinging of the swing blades, the back-and-forth change of the air flow direction can promote the air flow in the usage space. At the same time, in a certain space, it is not necessary to directly blow air on people to obtain a cool experience, effectively reducing the disadvantages of long-term blowing; with two swing blades, the swaying fan can achieve a blowing angle greater than 90 degrees or even 360 degrees, which is impossible for traditional fans. At the same time, the swaying fan adjusts the air flow through the internal and external swing blades, which is more direct and simple without increasing the load on the fan. Compared with products that achieve this purpose by adding air ducts, the air volume is larger under the same conditions.

[0011] In a further technical solution, the swing blades include at least one group of internal swing blades and at least one group of external swing blades; the internal swing blades are installed inside the fuselage above the fan assembly, and the internal swing blades are driven to swing inside the fuselage by a first driving device; the external swing blades are installed outside the fuselage, and the external swing blades are driven to swing by a second driving device to adjust the external air outlet angle; through the combined action of multiple groups of swing blades, the adjustable angle of the air outlet can be increased; the internal swing blades are controlled to swing by the first driving device to control the air flow to blow towards the air guiding surface of the external swing blades.

[0012] In a further technical solution, a frame-shaped outer bracket is provided outside the fuselage, and the external swing blades are installed on the outer bracket; an air outlet surface is provided on the outer shell, and the external swing blades are installed on the air outlet surface of the outer shell; the internal swing blades are installed on the air outlet surface or below the air outlet surface, and the angle is adjusted for the first time through the swinging of the internal swing blades; the angle is adjusted for the second time through the swinging of the external swing blades to control the angle of the air flow blown outwards.

[0013] In a preferred technical solution, rotating shafts are provided between both sides of the external swing blades and the outer bracket, and spiral teeth are provided on the surface of one of the rotating shafts; the second driving device includes: a second motor and a long transmission shaft driven by the second motor, and the long transmission shaft cooperates with the rotating shaft with spiral teeth to drive the external swing blades to rotate; in the way of worm and gear engagement, the external swing blades are driven to swing, with a simple structure, and at the same time, the rotation angle and speed of the external swing blades are uniform; the rotating shafts are hidden inside the outer bracket, which can beautify the appearance of the swaying fan.

[0014] In a preferred technical solution, the external swing blades are in a plate-shaped structure, and light-emitting components are provided on the external swing blades; a structure similar to a screen can be made between the external swing blades and the outer bracket. The swaying fan uses the external swing blades as the facade, and its appearance is significantly different from that of other fans, breaking through the constraints of the conventional fan shape; at the same time, pictures can be designed on the surface of the external swing blades to enhance the beauty; and light-emitting components are provided on the external swing blades, and the light-emitting components can be atmosphere lights or illuminating lights. The atmosphere lights can set off the atmosphere, and the illuminating lights can play a lighting role, enabling the swaying fan to be used as a lamp and increasing the performance of the product.

[0015] In the preferred technical solution, the outer bracket includes an inner bracket shell and an outer bracket shell, and a cavity is formed between the two; the second motor is installed inside the fuselage, and the long transmission shaft passes through the air outlet surface and extends into the cavity for storage; the above defines the specific structure of the outer bracket and the specific installation position of the second motor.

[0016] In the preferred technical solution, on the rotating shafts at both ends of the external swing leaf, a positive electric ring is provided on one rotating shaft, and a negative electric ring is provided on the other rotating shaft. Both the positive electric ring and the negative electric ring are connected with energized elastic pieces and are powered on through the energized elastic pieces; the external swing leaf includes a front panel, a back panel, and the light-emitting component arranged between the two; the fuselage is provided with a circuit board and a control panel, and the energized elastic pieces are electrically connected to both the circuit board and the control panel. The operation of the light-emitting component can be controlled through the control panel. At the same time, this power-on structure does not prevent the rotation of the external swing leaf, and the structure is very ingenious; the front panel and the back can be semi-transparent. When the light is not used, the light-emitting component is not exposed outside, and the external swing leaf serves as a decorative screen. When the light-emitting component is used, the light can shine outwards.

[0017] In the preferred technical solution, the internal swing leaf is installed inside the fuselage through an inner bracket. The internal swing leaf is provided with a plurality of blades, and the plurality of blades swing synchronously; the first driving device includes a first motor and a short transmission shaft driven by the first motor. The plurality of blades are connected by connecting rods, and the short transmission shaft drives the plurality of blades to swing synchronously; the space inside the fuselage is small. By means of controlling with a plurality of internal swing leaves, the air adjustment effect is better, and the plurality of swing leaves swing synchronously to switch the wind direction.

The air outlet surface is arranged on the front shell, and the front shell is covered with air outlets to form the air outlet surface; an air inlet is opened on the bottom shell or the side plate; holes for inserting and installing the lower end of the outer bracket are opened on the edge of the front shell; the area of the above air outlet surface is large, and the number of air outlets is large. Coupled with the cooperation of the motor, the air outlet volume is larger.

[0021] In a preferred technical solution, a groove through which the long drive shaft and the short drive shaft pass is provided on the inner bracket. The long drive shaft and the short drive shaft are symmetrically arranged, and a limiting structure for preventing the long drive shaft from shaking is arranged inside the outer bracket, so as to prevent the long drive shaft and the short drive shaft from shaking during use, thereby causing the fuselage to vibrate, reducing the vibration of the fuselage, and thus reducing noise.

[0022] In a preferred technical solution, it further includes: a control panel and a circuit board, which are used to control the operation of the swaying fan.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Oscillating fan, such as Figure 4 As shown, it includes: a fuselage 100, a fan assembly 200 installed inside the fuselage 100, and at least two groups of swing blades. The swing blades swing independently along parallel axes. The fan assembly 200 operates to form airflow. After the airflow is blown out from the fan assembly 200, it can flow along the surface of each swing blade in sequence. There can be multiple groups of swing blades, and each group of swing blades is arranged and distributed, and swings independently. Since they swing along parallel axes, they sweep air while swinging, simulating the effect of artificial fanning.

[0035] The swing blades include: at least one group of internal swing blades 300 and at least one group of external swing blades 400. The internal swing blades 300 are installed inside the fuselage 100 to adjust the internal air outlet angle; and the external swing blades 400 are installed outside the fuselage 100 to adjust the external air outlet angle.

[0036] In the following description, due to the description of angles, for the sake of convenience, Figure 5 The following table shows the benchmark. Figure 5 The inner swing leaf 300 and the outer swing leaf 400 are both arranged vertically, and the vertical angle is set as the reference 0°. Counterclockwise rotation is a negative angle, and clockwise rotation is a positive angle, which further limits the inner swing leaf 300 to rotate counterclockwise to the left to blow air as back air outlet, and the inner swing leaf 300 rotates clockwise to the right to blow air as forward air outlet.

[0037] See also Figures 1 - 3 As shown, it includes: a fuselage 100, a fan assembly 200 installed inside the fuselage 100, an internal swing leaf 300, and an external swing leaf 400 installed outside the fuselage 100.

[0038] The fuselage 100 is provided with an air outlet surface 101, which is covered with air outlets, and the external swing leaf 400 is installed above the air outlet surface 101;

[0039] The internal swing leaf 300 is driven by the first driving device 510 to swing inside the fuselage 100, and the external swing leaf 400 is driven by the second driving device 520 to swing outside the fuselage 100; and in the vertical state (reference 0°), the internal swing leaf 300 and the external swing leaf 400 are parallel.

[0040] The core of the present invention lies in: by means of the internal swing leaf 300 and the external swing leaf 400 to simulate the way of manual fanning to change the air flow direction back and forth. The internal swing leaf 300 swings within the fuselage 100, which can control the air flow to blow out from the front or the back, and first adjust the internal air outlet angle; and then through the swing of the external swing leaf 400, the air outlet angle can be adjusted for the second time (adjust the external air outlet angle). Finally, an air outlet range greater than 90 degrees can be achieved. If the number of layers of the swing leaf is increased, even the adjustment of blowing at a 360-degree corner can be realized.

[0041] The swaying fan controls the operation of the fan assembly 200 through the control system, determining the wind speed and air volume of the air outlet, such as Figure 5 shown. When the product needs to blow air to the left or right, the control system controls the operation of the first driving device 510, and then controls the internal swing leaf 300 to rotate clockwise or counterclockwise within 45 degrees. The control system controls the operation of the second driving device 520, and then controls the external swing leaf 400 to rotate clockwise or counterclockwise within 105 degrees, so as to realize that the product blows air to the left or right first, and controls whether to perform air sweeping and the air sweeping range according to the functional requirements of the product. When air sweeping is required, the external swing leaf 400 can be controlled to swing, and the swinging angle can control the air sweeping range.

[0042] Such as Figure 5 shown, in the figure, the installation direction of the internal swing leaf 300 is perpendicular to the paper surface. The left side of the external swing leaf 400 is the back, and the right side of the external swing leaf 400 is the front; Figure 5 In, the internal swing leaf 300 is vertically arranged. If air blows out at this time, the air flow is generally evenly blown out vertically from the front and the back of the external swing leaf 400; if the internal swing leaf 300 does not move and the external swing leaf 400 rotates counterclockwise by an angle of -45°, the air flow is first vertically blown out through the internal swing leaf 300, then blows to the external swing leaf 400, and flows along the surface of the external swing leaf 400 and is blown out approximately at -45° (backward); if the internal swing leaf 300 does not move and the external swing leaf 400 rotates clockwise by an angle of 45°, the air flow is first vertically blown out through the internal swing leaf 300, then blows to the external swing leaf 400, and flows along the surface of the external swing leaf 400 and is blown out approximately at 45° (forward).

[0043] More specifically, Figures 6 - 8 is a schematic diagram of the swaying fan blowing air to the back of the external swing leaf 400; the internal swing leaf 300 is vertically arranged and remains stationary, blowing air upward, and the external swing leaf 400 rotates counterclockwise by an angle of about -15°. The blowing angle is as Figure 6 shown by the arrow. After the air blown upward blows to the external swing leaf 400, it is blown out along the external swing leaf 400 at an angle of about -15° outward;

[0044] Such as Figure 7As shown by the arrow direction, the external swing leaf 400 continues to rotate counterclockwise by an angle of about -40°. After the wind blowing upward blows onto the external swing leaf 400, it blows out at an angle of about -45° outward along the external swing leaf 400.

[0045] Figure 6 and Figure 7 In, the blowing angles are all inclined towards the upper left. As the external swing leaf 400 rotates counterclockwise, the air outlet angle is adjusted.

[0046] Such as Figure 8 shown, the internal swing leaf 300 rotates counterclockwise by about -30°, and the external swing leaf 400 rotates counterclockwise by about -80°. The air flow blows out from the inside of the fuselage 100 at an angle of -30°, and after blowing onto the external swing leaf 400, it blows out at an angle of about -80° outward along the external swing leaf 400.

[0047] Similarly, it can be known that if it is necessary to blow air onto the front of the external swing leaf 400, the internal swing leaf 300 and the external swing leaf 400 can be controlled to rotate clockwise according to the above principle; as Figure 9 shown, if positive air outlet is required, the external swing leaf 400 is rotated clockwise, then positive air outlet is achieved, Figure 9 in which the rotation angle of the external swing leaf 400 is about 40°, and positive blowing at 40° is performed.

[0048] During the use of the swaying fan, either the external swing leaf 400 or the internal swing leaf 300 can be adjusted to a good angle and then fixed, and the other swings back and forth. It is also possible to choose that the external swing leaf 400 and the internal swing leaf 300 swing simultaneously according to the set degree. In the above Figures 6 - 9 If the internal swing leaf 300 is kept stationary and the external swing leaf 400 swings driven by the second driving device 520, the purpose of sweeping the wind can be achieved, and different air outlet angles can be changed; if the external swing leaf 400 is kept stationary and the internal swing leaf 300 swings driven by the first driving device 510, although the air flow still flows along the surface of the external swing leaf 400 and the air outlet angle remains unchanged, the swing of the internal swing leaf 300 can change the wind resistance and the air volume, simulate natural wind, and make the use more comfortable.

[0049] When the internal swing leaf 300 and the external swing leaf 400 swing simultaneously according to the rule, the wind flow direction can be changed back and forth, and the swaying fan can be controlled to continuously sweep the wind, making the use more comfortable;

[0050] Only several air outlet angles are listed above. Actually, there are many other air outlet angles; it can be known from the above that the wind direction adjustment angle of the swaying fan on the external swing leaf 400 is greater than 90°, and the adjustment range is wide.

[0051] In the above description, most of the air flow blown out from inside the body 100 is blown out in different directions according to different uses as described above. However, a very small part of the air does not flow along the arrow direction but overflows and blows out around the edge of the external swing blade 400. However, it is only a very small part and will not affect the normal use of the swaying fan. At the same time, it also strengthens the air circulation around.

[0052] Next, a specific structural manner of the swaying fan will be further described.

[0053] Body 100:

[0054] It has a housing 110 and a fan assembly 200 installed inside the housing 110;

[0055] The described housing 110 is mainly used for installing the fan assembly 200 and other components. The material and shape of the housing 110 are not limited; the housing 110 has: side plates 111, a bottom shell 112 and a front shell 113. The three enclose an internal cavity, and the front shell 113 is covered with air outlets to form the air outlet surface 101; an air inlet is provided on the bottom shell 112 or the side plates 111; an anti-slip pad is provided at the bottom of the bottom shell 112.

[0056] The fan assembly 200 includes: a motor 210, a motor base 220 and a fan blade 230. The air flow enters the body from the air inlet, and its path is: air inlet --- fan blade ---- internal swing blade ---- air outlet; therefore, the internal swing blade 300 is installed corresponding to the air outlet and is located between the air outlet and the fan blade 230.

[0057] The described motor 210 can be a brushless motor.

[0058] The motor base 220 includes: a bottom plate 221 and a frustum 222. The inside of the frustum 222 forms a space for assembling the motor 210; the fan blade 230 is installed on the frustum 222 and is driven by the motor 210; the bottom plate 221 is installed in cooperation with the housing 110 of the body 100, and an installation position 2211 for the first motor 511 and the second motor 521 is formed on the bottom plate 221. The installation position 2211 is generally sleeve-shaped, and the first motor 511 and the second motor 521 are installed in the installation position 2211, making the product structure more concentrated and eliminating the need to add other structures for installing the first motor 511 and the second motor 521 inside the body 100; between the bottom plate 221 and the bottom shell 112, it can be snap-fitted, screwed, etc.; as Figure 2 shown, a buckle is provided at the bottom of the bottom plate 221 to facilitate subsequent snap connection with the bottom shell 112 of the housing 110.

[0059] In addition, sound-absorbing cotton can be provided inside the base 220. The motor 210 is installed inside the base 220, and the noise generated during the operation of the motor 210 is attenuated by the sound-absorbing cotton.

[0060] The transmission between the internal swing blade 300 and the first driving device 510 can adopt a meshing structure, and the transmission between the external swing blade 400 and the second driving device 520 can also adopt a meshing structure.

[0061] In this embodiment, the internal swing blade 300 is installed inside the fuselage 100, and the air flow is blown out after passing through the internal swing blade 300 - - - air outlet - - - external swing blade 400. In another embodiment, the internal swing blade 300 can also be directly installed at the air outlet.

[0062] The internal swing blade 300 is installed inside the fuselage 100 through the inner bracket 310. The internal swing blade 300 is provided with a plurality of blades 320. Here, three blades 320 are provided, and the three blades 320 are connected by a connecting rod 302 passing through a position 303. The inner bracket 310 is provided with two symmetrical ones, the inner bracket 310 is in a semi-circular shape, the inner wall of the inner bracket 310 is provided with holes for the internal swing blade 300 to be pivotally connected, and the outer wall is provided with grooves for the long transmission shaft 522 and the short transmission shaft 512 to pass through; the inner bracket 310 is fixedly installed inside the fuselage 100.

[0063] Both ends of the internal swing blade 300 are provided with shaft parts 301. The shaft parts 301 are inserted into the holes opened on the inner wall of the inner bracket 310, and the internal swing blade 300 is driven to swing by the first driving device 510; as Figure 2 shown, the internal swing blade 300 is installed close to the front shell 113 of the housing 100.

[0064] The first driving device 510 includes: a first motor 511 and a short transmission shaft 512 driven by the first motor 511. One end of the short transmission shaft 512 is connected to the first motor 511, and the other end is equipped with a turbine; and the three blades 320 are connected by a connecting rod 302. A turbine 5122 is fixedly connected to the shaft part 301 of one of the blades 320. The rotation of the short transmission shaft 512 drives the turbine 5122 to rotate, driving the internal swing 300 to swing synchronously;

[0065] Further, the first motor 511 can be directly connected to the short transmission shaft 512 to drive its rotation, or can drive the short transmission shaft 512 to rotate through a belt transmission structure.

[0066] Optionally, there are other ways to realize the swing of the internal swing blade 300. For example, by combining an eccentric wheel structure with a swing arm to drive the internal swing blade 300 to swing is also possible.

[0067] Further, although the internal swing leaf 300 can rotate clockwise to the 80° position or counterclockwise to the -80° position, in actual applications, the rotation range of the internal swing leaf 300 can be controlled to be between -45° and +45°.

[0068] The external swing leaf 400 is installed outside the fuselage 100 through the outer bracket 120. The outer bracket 120 has a frame-like structure, and the external swing leaf 400 has a plate-like structure. The external swing leaf 400 is rotatably installed on the outer bracket 120, forming a structure similar to a screen, which not only achieves the function of adjusting the wind direction but also enhances the beauty of the product. An opening for inserting and installing the lower end of the outer bracket 120 is provided on the edge of the front shell 113. The outer bracket 120 is inserted and installed in the slot of the side plate 111 through the opening of the front shell 113, and after installation, the outer bracket 120 can be further fixed by screwing.

[0069] As Figure 1 shown, the fuselage 100 is columnar, the outer bracket 120 is located on the diameter of the fuselage 100, and the external swing leaf 400 is also located on the same diameter of the fuselage 100.

[0070] Rotating shafts 410 are provided between both sides of the external swing leaf 400 and the outer bracket 120. The rotating shafts 410 are generally arranged at a position slightly lower than the middle of the external swing leaf 400, and spiral teeth are provided on the surface of one of the rotating shafts 410.

[0071] The second driving device 520 includes: a second motor 521 and a long transmission shaft 522 driven by the second motor 521. The long transmission shaft 522 cooperates with the rotating shaft 410 with spiral teeth to drive the rotating shaft 410 to rotate, thereby causing the external swing leaf 400 to swing forward or backward. The second motor 521 and the long transmission shaft 522 can be directly connected or connected through a belt structure. In this embodiment, the long transmission shaft 522 and the second motor 521 are connected through a belt structure.

[0072] The first motor 511 and the second motor 521 can be stepper motors.

[0073] The outer bracket 120 includes: a bracket inner shell 121 and a bracket outer shell 122, which form a receiving cavity therebetween. The rotating shaft 410 passes through the bracket inner shell 121 and enters the receiving cavity, and the long transmission shaft 522 is stored inside the outer bracket 120 to beautify the product structure.

[0074] The first motor 511 and the second motor 521 are both installed in the installation position 2211 of the bottom plate 221, and the first motor 511 and the second motor 521 are symmetrically distributed.

[0075] Furthermore, one end of the short transmission shaft 512 is connected to the first motor 511, and the other end is snapped into a groove reserved on the inner bracket 310 and connected to the internal swing leaf 300; one end of the short transmission shaft 512 is inserted into a corresponding bearing assembly hole of the bottom plate 221, and the other end passes through the shaft hole of a bearing block mounted on the inner bracket 310, defining that it can rotate around its own axis; one end of the long transmission shaft 522 is connected to the second motor 521, and the other end is connected to the external swing leaf 400, and both ends of the long transmission shaft 522 are respectively assembled into corresponding bearing assembly holes of the outer bracket 120 and the bottom plate 221, defining that it can rotate around its own axis. Since the length of the long transmission shaft 522 is relatively long, in order to prevent possible deformation and shaking during rotation, a limiting structure for preventing the long transmission shaft 522 from shaking can be provided inside the outer bracket 120. This limiting structure can be a card slot, defining that it can rotate within the card slot but cannot deform and shift, reducing the possible vibration.

[0076] The external swing leaf 400 can achieve 360° clockwise and counterclockwise rotation. However, in actual use, such a large rotation angle is not required. The swing angle of the external swing leaf 400 is generally controlled between -105° and +105°.

[0077] In the above structure, since the external swing leaf 400 is similar to the structure of a screen, in the cold season, when the swaying fan is not in use, it can also play a decorative role. Decorative paintings can also be added to the surface of the external swing leaf 400; in order to increase the functions of the swaying fan, in a further embodiment, a light-emitting component 440 is provided on the external swing leaf 400.

[0078] Furthermore, the external swing leaf 400 includes: a panel 420, a back panel 430, and the light-emitting component 440 provided between the two. The panel 420 and the back panel 430 can be made of light-transmitting materials. Then, when the light-emitting component 440 is powered on, light emission can be achieved. Here, the light-emitting component 440 can be set in the form of an ambient light, or a lighting lamp, etc.; here, the light-emitting component 440 can be powered on by setting a storage battery or directly connecting to a circuit board 620 on the fuselage 100.

[0079] Furthermore, as Figure 4 shown, the light-emitting component 440 is a light-emitting panel. After the light-emitting panel is powered on, it can display the set patterns or characters, etc., playing a decorative role;

[0080] Furthermore, the light-emitting component 440 can be a lighting panel, capable of emitting light rays that achieve a lighting effect.

[0081] Furthermore, the light-emitting component 440 is installed inside the external swing leaf 400. Since the external swing leaf 400 can rotate, the power supply of the light-emitting component 440 is adopted in the following way: on the rotating shafts 410 at both ends of the external swing leaf 400, a positive electric ring is arranged on one rotating shaft 410, and a negative electric ring is arranged on the other rotating shaft 410. Both the positive electric ring and the negative electric ring are connected with energizing elastic pieces, and power is connected through the energizing elastic pieces.

[0082] Furthermore, as Figure 5 shown, the swaying fan can realize air outlet in the forward direction (to the left) and the backward direction (to the right). However, if it is necessary to blow air forward or backward, the swaying fan needs to be rotated. Therefore, a rotating base can be added to the bottom of the fuselage 100. The rotating base can drive the entire fuselage 100 to rotate. After the rotating base drives the fuselage 100 to rotate forward by 90°, the air blowing in the front and back directions can be realized. Then, when in use, the air outlet direction can be switched at a large angle in the horizontal direction, and the air outlet direction can also be at a large angle in the vertical direction. Compared with the traditional direction, the air blowing angle is wider and the use effect is better.

[0083] Furthermore, multiple groups of internal swing leaves 300 can be provided for guiding air; or multiple external swing leaves 400 can be provided for guiding air.

[0084] Furthermore, the swaying fan further includes: a control panel 610 and a circuit board 620. The control panel 610 is installed on the front of the swaying fan. The control panel 610 can be controlled by mechanical buttons or touch control; mainly, it can adjust: 1. Adjust the rotation speed of the fan assembly 200, which is to control the air volume;

[0085] 2. Adjust the swing of the internal swing leaf 300, which is to assist in adjusting the air outlet angle;

[0086] 3. Adjust the swing of the external swing leaf 400, which is also to adjust the air outlet angle;

[0087] 4. Control the operation of the light-emitting component 440.

[0088] For the swaying fan, a specific control system can be set. Since the fan can adjust the air flow at a large angle and in a large range, if the rotation of the internal swing leaf and the rotation of the external swing leaf are manually controlled, then after multiple adjustments, problems may occur in the swing of the internal swing leaf and the swing of the external swing leaf. Therefore, it can be set that when the swaying fan is controlled to close, the internal swing leaf and the external swing leaf are reset to 0°; or, after the power is cut off and then restored, the internal swing leaf and the external swing leaf are automatically reset to 0°.

[0089] The following lists an electric control operation mode of the swaying fan:

[0090] As Figure 4As shown, when the fan assembly 200 is working, press the button 1 on the control panel 610. The second driving device 520 drives the external swing leaf 400 to rotate forward by 90 degrees at a selected speed, and the first driving device 510 drives the internal swing leaf 300 to swing back and forth cyclically from 0 degree to 45 degrees to 0 degree forward at a selected speed.

[0091] Press the button 1 on the control panel 610 again. The first driving device 510 drives the internal swing leaf 300 to be fixed at 30 degrees forward at a selected speed and then power off, and the second driving device 520 drives the external swing leaf 400 to swing back and forth cyclically from 85 degrees forward to 95 degrees to 85 degrees at a selected speed.

[0092] Press the button 1 on the control panel 610 again. The second driving device 520 powers off in the current state.

[0093] Press the button 1 on the control panel 610 again. The first driving device 510 and the second driving device 520 control the external swing leaf 400 and the internal swing leaf 300 to reset and then power off, and so on in a cycle.

[0094] In addition to the user controlling the operation of the internal swing leaf and the external swing leaf according to the current usage requirements; the control system can also set multiple fixed operation modes for the customer to choose; the control principle and the operation mode belong to the circuit part of the product, which also includes but is not limited to speed control, lamp tube intensity control, timing adjustment, etc., and will not be elaborated in detail here.

[0095] In addition, a wireless control part is also provided on the circuit board. For example, the circuit board includes a WiFi module, which supports data communication between the mobile phone and the product through WiFi. Through the mobile phone, the product can perform custom electronic function parameter setting, control the operation of the motor and monitor its state, control the operation of the lamp circuit and monitor its state, including timing setting, adjustment of two motor speeds, power intensity of the light-emitting component, definition of button functions, etc.

[0096] In addition, Figure 1 the swaying fan in can be floor-standing or desktop, both of which are used on a flat surface. Optionally, the swaying fan can be made into a wall-mounted type and installed on a vertical plane, and a mounting bracket can be added to the bottom of the fuselage 100 accordingly.
