Description

A three-dimensional rotating swing air outlet device for preventing electric wire winding and its swing control method Technical Field

[0001] The present invention belongs to the technical field of air outlet equipment, and in particular relates to a three-dimensional rotating swing air outlet equipment for preventing electric wire winding and a shaking control method thereof. Background Art

[0002] A fan is a household appliance that blows air to the outside and accelerates air circulation. In order to increase the air supply area of ​​the fan, existing fans have improved the rotating shaft structure of their electric air outlet components (fan heads), thereby supplying air to more areas and increasing the air supply range.

[0003] For example, the three-dimensional pendulum structure disclosed in Chinese patent application number 201721500103.X arranges the axis lines of the first rotating shaft (which drives the fan blades) and the second rotating shaft (which drives the electric air outlet component) to be coplanar or skewed, and the angle between them is not equal to 0°, 90°, or 180°. This allows the electric air outlet component to rotate around the second rotating shaft. However, this fan can only deliver air to one side, and the electric air outlet component rotates around the second rotating shaft, so its air delivery range is still very small and not three-dimensional.

[0004] For example, the multi-angle rotating oscillating fan disclosed in the Chinese patent application number 202222237447.3 is provided with a first rotating shaft and a second rotating shaft. Under the action of the two sets of rotating shafts, the oscillating fan body can rotate 360 ​​degrees around the central axis of the first rotating shaft, and can also rotate around the central axis of the second rotating shaft, which increases the air supply range of the oscillating fan.

[0005] The battery of the multi-angle rotating oscillating fan is arranged in the first base. In order for the first drive device that drives the fan blades to rotate to obtain power, a wire needs to be arranged. One end of the wire is electrically connected to the battery, and passes through the first base, the first bracket and the second base in sequence, and is finally electrically connected to the first drive device to supply power to the first drive device. However, during use, when the oscillating fan body rotates around the first rotation axis, the first drive device rotates synchronously with the oscillating fan body. At this time, the first drive device rotates relative to the battery, and the wire will be twisted. In order to further increase the air supply range of the oscillating fan, the oscillating fan body is made to rotate around the second rotation axis at the same time, and the wire will be further twisted, which can easily break the wire, damage the insulation layer of the wire, and cause circuit failure and other problems. More seriously, there may even be extremely serious safety problems in use (such as electric shock or fire caused by overheating of the wire).

[0006] The fan body of the above oscillating fan rotates around multiple sets of fixed shafts, thereby increasing the air supply range. In existing fans, the shafts are also set to a rotatable state, thereby increasing the air supply range of the fan.

[0007] For example, Chinese patent application number 87203899.8 provides an omnidirectional oscillating ceiling fan. This ceiling fan utilizes a universal joint mechanism to support the oscillating mechanism (the central axis of the oscillating mechanism is the aforementioned rotating shaft). However, when used as a desktop or floor fan, the oscillating ceiling fan with this structure can only deliver air in one direction, resulting in a limited air delivery range. Furthermore, this technology is only suitable for ceiling fans; if used on desktop or floor fans, mechanical damage may occur.

[0053] A shaking control method for a three-dimensional rotating swing air outlet device for preventing electric wire winding is applied to the three-dimensional rotating swing air outlet device for preventing electric wire winding obtained by any of the above methods.

[0054] cyclically controlling the first motor to drive the turntable to rotate forwardly around its rotation axis by a preset angle and then reversely reset, wherein the preset angle is configured to be between 1° and 360°;

[0055] During the rotation of the turntable, the second motor is continuously controlled to drive the pin to rotate around its rotation axis.

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] One end of the first connecting member and the second connecting member are both connected to the universal joint, forming a transmission structure connecting the electric air outlet component and the pin, and the other ends are respectively connected to the pin and the electric air outlet component. Since the rod body of the pin forms an inclination angle between 1° and 60° relative to the rotating shaft of the second motor, when the pin is driven by the second motor to rotate 360°, the pin drives the second connecting member or the universal joint to rotate synchronously, and then drives the electric air outlet component through the corresponding connecting member to rotate 360° in an infinite loop in the same direction without rotating, or rotating at any angle of 360 degrees. In this way, at every position where the turntable can rotate, the electric air outlet component can rotate to multiple directions on the same side, which makes its air supply more three-dimensional and the air supply range larger. Combined with the rotation of the chassis, the electric air outlet component can supply air to multiple sides, which further increases the air supply range of the electric air outlet component.

[0058] In practice, because power needs to be supplied to the electric air outlet, an electric wire must be connected to the electric air outlet. When the chassis is stationary and the electric air outlet is driven by the swing head assembly to swing, the electric air outlet only delivers air in multiple directions on one side. This prevents the electric air outlet from rotating, preventing the wires from twisting or tangling. This prevents wire breakage or insulation damage, which could lead to circuit failures, or even serious safety issues such as electric shock or fire caused by leakage. This provides a structural foundation for solving the problem of wires being easily damaged by twisting and tangling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0080] In the description of the present invention, it should be understood that the terms "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0081] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood in a broad sense. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0082] Furthermore, those skilled in the art may combine and integrate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0083] The technical solution of the present invention will be further described below with reference to Figures 1-21.

[0084] Example 1

[0085] A three-dimensional, oscillating air outlet device that prevents wire entanglement, as shown in Figure 1, comprises a base 1 placed on an external surface as a support for the three-dimensional, oscillating air outlet device, an oscillating head assembly 2 connected to the base 1, and a motorized air outlet component 3 connected to the oscillating head assembly 2 for delivering air to the user. In practical applications, the air outlet device can function as a cooling or heating fan, depending on the temperature of the delivered air. Depending on the usage scenario, the air outlet device can function as a desktop fan or a floor fan.

[0086] A turntable 13 and a first motor 12 are provided on the base 1, and the first motor 12 is used to drive the turntable 13 to rotate. In this embodiment, specifically, referring to Figure 2, the base 1 includes a bottom cover 11 and the above-mentioned turntable 13 rotatably connected to the bottom cover 11. The first motor 12 is fixedly connected in the base, and can be connected to the bottom cover 11 or to the turntable 13. When the rotating shaft of the first motor 12 rotates, the turntable 13 is driven to rotate through the transmission structure, and the turntable 13 drives the electric air outlet component 3 to rotate through the swing head assembly 2. In this way, the electric air outlet component 3 can supply air to different sides (such as the front, left, right and right sides) in the space.

[0087] The transmission structure mentioned above can be a gear transmission or a crank transmission, which can adopt the existing transmission structure and will not be described in detail here.

[0088] In this embodiment, the electric air outlet component 3 includes fan blades 31, a third motor 32 for driving the fan blades 31, and a wind cover 33 arranged outside the two. This structure is a common structure of the existing electric air outlet component 3 and will not be repeated here.

[0089] Referring to Figures 2-14 , the swing head assembly 2 includes a universal joint 21, a pin 22, a second motor 23, a first connector 24, and a second connector 25. The outer ring 212 of the universal joint is hinged to the first connector 24, which is fixedly connected to one of the base 1 and the electric air outlet component 3. The inner ring 211 of the universal joint is fixedly connected to the other of the base 1 and the electric air outlet component 3 via the second connector 25. The second motor 23 is used to drive the pin 22 to rotate about the rotation axis of the second motor 23. The shaft of the pin 22 forms an inclination angle between 1° and 60° relative to the rotation axis of the second motor 23, thereby forming a horizontal tilt. In actual products, this inclination angle can be adjusted within the above range. The end of the pin 22 away from the second motor 23 connects to the inner ring 211 of the universal joint or the second connector 25, thereby transmitting power.

[0090] As one embodiment, referring to Figures 2-4 , a second motor 23 is fixedly connected to the turntable 13. One end of a first connector 24 is fixedly connected to the turntable 13, and the other end of the first connector 24 is articulated to the outer ring 212 of a universal joint. The inner ring 211 of the universal joint is rotatably connected to the outer ring 212 of the universal joint and is fixedly connected to the electric air outlet component 3 via a second connector 25. The top end of a pin 22 is connected to the inner ring 211 of the universal joint, while the bottom end of the pin 22 is driven to rotate by the second motor 23. When the electric air outlet component 3 is swung by the swing head assembly 2, the pin 22 is driven to rotate by the second motor 23. When driven, the pin 22 revolves around the line L1. This rotation of the pin 22 drives the inner ring 211 of the universal joint, which in turn drives the second connector 25 and the electric air outlet component 3, thereby achieving 360° rotation of the electric air outlet component 3. During the swinging process of the pin 22, if the turntable 13 does not rotate, the air outlet direction is toward multiple directions on one side. Figures 5 to 8 are schematic diagrams of the state in which the electric air outlet component 3 blows air toward the left side as shown in the figure under the action of the swing head assembly 2 when the turntable 13 does not rotate. As shown in the figure, under the action of the swing head assembly 2, the electric air outlet component 3 can rotate and supply air toward the left rear, left upper, left front, and left directions as shown in the figure. If the turntable 13 also rotates during the process in which the swing head assembly 2 drives the electric air outlet component 3 to rotate, the turntable 13 can drive the electric air outlet component 3 to rotate to multiple sides (such as the left side, the back side, the right side, and the front side). For schematic diagrams of the state in which the turntable drives the electric air outlet component to rotate to different sides, see Figures 9 to 12 (in the figure, the shaking head assembly also rotates when the turntable rotates).

[0091] The line L1 is the center line of the universal joint 21 in the vertical direction.

[0092] As another embodiment, referring to Figures 13-14, a second motor 23 is provided on the electric air outlet component 3. One end of a first connecting member 24 is fixedly connected to the electric air outlet component 3. The other end of the first connecting member 24 is hinged to the outer ring 212 of the universal joint. The inner ring 211 of the universal joint is rotatably connected to the outer ring 212 of the universal joint and is fixedly connected to the turntable 13 via a second connecting member 25. The top end of the pin 22 is connected to the rotating shaft of the second motor 23, and the bottom end is fixedly connected to the inner ring 211 of the universal joint. The electric air outlet component, the second motor 23, and the first connecting member 24 are all relatively fixed to form a relatively fixed integral structure. When the electric air outlet component 3 is swung by the swing head assembly 2, the pin 22 is driven by the second motor 23 to rotate. The rotation of the pin 22 causes the above integral structure to rotate relative to the outer ring 212 of the universal joint and the second connecting member 25, thereby achieving 360-degree rotation of the electric air outlet component 3. The above specific settings of the swing head assembly 2 can realize 360° rotation of the electric air outlet component 3. In actual use, the solution of installing the second motor 23 on the turntable 13 has smaller transmission resistance, more stable use, and is more suitable for actual production applications.

[0093] In the above-mentioned three-dimensional rotating air outlet device for preventing electric wire winding in this embodiment, one end of the first connecting member 24 and the second connecting member 25 are both connected to the universal joint 21, and the other ends are respectively connected to the turntable 13 and the electric air outlet component 3, forming a transmission structure connecting the electric air outlet component 3 and the turntable 13. Because the rod of the pin 22 forms an inclination angle between 1° and 60° relative to the rotating shaft of the second motor 23, when the pin 22 is driven by the second motor 23 to rotate 360°, the pin 22 drives the inner ring 211 of the universal joint to rotate synchronously, and then drives the electric air outlet component 3 through the corresponding connecting members to rotate 360° in an infinite loop in the same direction without rotating, or rotating at any angle within 360 degrees. In this way, at each position where the turntable 13 can rotate, the electric air outlet component 3 can rotate to multiple directions on the same side, making the air supply more three-dimensional and expanding the air supply range. Combined with the rotation of the chassis, the electric air outlet component 3 can supply air to multiple sides, further expanding the air supply range of the electric air outlet component 3. Furthermore, in actual use, since power needs to be supplied to the electric air outlet component 3, an electric wire 4 needs to be provided to connect to the electric air outlet portion. When the chassis is not rotating and the electric air outlet component 3 is driven by the swing head assembly 2 to swing, the electric air outlet component 3 only supplies air in multiple directions on one side. In this way, the electric air outlet component 3 does not cause the electric wire 4 to rotate, so that the electric wire 4 does not twist or tangle, avoiding the wire 4 from being broken or the insulation layer damaged, which may cause circuit failure, or even serious safety issues such as leakage, electric shock, overheating and fire. This provides a structural basis for solving the problem of the wire 4 being easily damaged by twisting and entanglement.

[0094] In order to supply power to the electric air outlet component 3, referring to Figures 15 to 18, the three-dimensional rotating air outlet device that prevents electric wire winding has an electric wire 4 for supplying power to the electric air outlet component 3. The routing of the electric wire 4 bypasses the rotation space of the pin 22, so that the pin 22 can rotate smoothly to avoid interference from the electric wire 4, and the electric wire 4 will not be rotated together with the pin 22 and become entangled, torn, twisted and broken, thereby causing circuit failure and safety problems. Since the length of the electric wire 4 required for the electric air outlet component 3 in different orientations is different, the arrangement of the electric wire 4 on the three-dimensional rotating air outlet device that prevents electric wire winding is configured to form a movable margin so that the electric wire 4 has the ability to move with the swing of the electric air outlet component 3. This ensures that the electric wire 4 will not be torn during the swinging process, thereby affecting the electrical connection.

[0095] In this embodiment, a housing 14 is fixed to the top surface of the turntable 13, the swing head assembly 2 is accommodated in the housing 14 and covered by the housing 14, the corresponding connector can extend out of the housing 14 to connect with the electric air outlet component 3, and the wire 4 extends upward from the base 1 and is then connected to the electric air outlet component 3. Specifically, referring to Figure 15, the second connector 25 is a cylindrical structure with both ends through, and a through hole 252 is provided on the inner wall of the housing 14 for the power supply line 4 to pass through. The wire 4 is configured to extend upward from the base 1 along the inner wall of the housing 14, bypass the universal joint 21 and the pin 22, and then pass through the through hole 252 to enter the inner cavity of the second connector 25, thereby supplying power to the electric air outlet component 3. During the wiring process, when the wire 4 is arranged upward along the inner wall of the housing 14, a little more wire 4 can be reserved to keep the wire in a loose state to form the above-mentioned movable margin, ensuring that the electric air outlet component 3 swings and does not tear the wire 4. Of course, it is also possible to leave sufficient length of wire 4 between the inner sidewall of housing 14 and second connector 25 to maintain a loose state, or to leave sufficient length of wire 4 inside second connector 25 to maintain a loose state, ultimately ensuring that wire 4 will not be torn. The above-mentioned provision of housing 14 to cover swing head assembly 2 and to position wire 4 within housing 14 effectively protects wire 4, making it less susceptible to damage, thereby increasing the service life and safety of the power supply circuit and other circuits. It also prevents external objects from affecting the transmission between swing head assembly 2 and electric air outlet component 3, ensuring stable and reliable transmission between the two and reducing transmission resistance. Furthermore, the provision of housing 14 also enhances the aesthetics of the entire device.

[0096] When the wires 4 are arranged to extend upwardly along the inner wall of the housing 14 , the wires 4 can be restricted on the inner wall, thereby preventing the wires 4 from affecting the rotation of the pin 22 .

[0097] As another alternative embodiment, referring to Figures 4 and 16 , the universal joint 21 is a cross universal joint. The outer wall of the universal joint's inner ring 211 is provided with a first rotating shaft 2111, which is hingedly connected to the universal joint's outer ring 212. The outer wall of the universal joint's outer ring 212 is provided with a second rotating shaft 2121, which is hingedly connected to the first connecting member 24. The axis of the first rotating shaft 2111 is perpendicular to the axis of the second rotating shaft 2121. The second connecting member 25, connected to the universal joint's inner ring 211, and the electric air outlet component 3 can rotate both relative to the first rotating shaft 2111 and relative to the second rotating shaft 2121 through the universal joint's inner ring 211. The second rotating shaft 2121 and the second connecting member 25 are both hollow and connected. During wiring, the wire 4 extends upward from the base 1, bypasses the pin 22, passes through the hollow portion of the second rotating shaft 2121, and enters the second connecting member 25, thereby supplying power to the electric air outlet component 3. To ensure that the wires have a certain amount of margin for movement, as in the previous embodiment, when the wires 4 are arranged upward along the inner wall of the housing 14, a little more wire 4 can be reserved to keep the wires in a relaxed state, or to allow the wires 4 to pass through the second rotating shaft 2121 with sufficient length to remain relaxed, or to allow the wires 4 to pass through the second connecting member 25 with sufficient length to remain relaxed, ultimately ensuring that the wires 4 will not be torn off. The second rotating shaft 2121 and the second connecting member 25 are hollow, and the wires 4 extend upward along the inner wall of the housing 14 and then pass through the inner cavities of the two to power the third motor 32, without having to bypass the universal joint 21 and be arranged above the universal joint 21 as in the previous embodiment. This allows the housing 14 to be shortened in height, reducing the size of the housing 14 and the entire air outlet device, making the entire device more compact.

[0098] In order to reduce the rotational resistance of the universal joint and improve the rotation effect of the universal joint, the first rotating shaft 2111 and the outer ring 212 of the universal joint, and the second rotating shaft 2121 and the first connecting member 24 are connected via bearings.

[0099] As a preferred wiring embodiment, referring to Figures 17-18, the universal joint 21 is a spherical universal joint. A spherical cabin 2123 is provided within the outer ring 212 of the universal joint. The inner ring 211 of the universal joint is spherical, and its outer wall is in rolling contact with the inner wall of the spherical cabin 2123. Compared with a cross universal joint, this reduces transmission resistance and improves transmission effect. A through hole 2124 is provided in the side wall of the spherical cabin 2123, and a wire passage 2112 is provided in the inner ring 211 of the universal joint. One end of the wire passage 2112 is aligned with the through hole 2124, and the other end is connected to the second connecting member 25. During wiring, the wire 4 extends upward from the base 1, passes through the through hole 2124 and the wire passage 2112, and enters the second connecting member 25 to supply power to the electric air outlet component 3. A gap exists between the wire passage 2112 and the wire 4 for the wire to move. Similar to the previous two wiring implementations, in order to ensure that the wires 4 have a certain amount of movable margin, when the wires 4 are arranged upward along the inner wall of the housing 14, more wires 4 can be reserved to keep the wires in a relaxed state, or the wires 4 passing through the through-hole 2124 and the threading channel 2112 can be left with sufficient length to keep them in a relaxed state, or the wires 4 in the second connecting member 25 can be left with sufficient length to keep them in a relaxed state.

[0100] In this embodiment, the air outlet device is provided with a transmission member 26, one end of which is connected to the rotating shaft of the second motor 23. One end of the pin 22 is fixedly connected to the tilting member 251, and the other end of the pin 22 slides and nests with the transmission member 26, thereby allowing the pin 22 to move along its shaft. By arranging one end of the pin 22 and the transmission member 26 to slide and nest, the two are in a state of relative movement during the transmission process, which provides a structural basis for solving the winding problem of the ball joint. In addition, the sliding nesting between the pin 22 and the transmission member 26 can also reduce the transmission resistance between the pin 22 and the tilting member 251 and the transmission member 26, thereby improving the smoothness of the transmission, which is explained below.

[0101] During actual use, the inner ring 211 of the universal joint will still rotate slightly under the influence of the pin 22. After prolonged use, one end of the wire passage 2112 of the inner ring 211 of the universal joint may not align with the through hole 2124 of the spherical chamber 2123, and may even become misaligned, causing the wire to be compressed between the inner ring 211 and the outer ring 212, damaging the wire 4. Therefore, in this embodiment, referring to Figure 19, the pin 22 is provided with a positioning member 222 extending from the bottom and having a non-circular cross-section. The positioning member 222 can be ellipsoidal, square, or other non-spherical three-dimensional structure. This embodiment uses the ellipsoidal shape as an example for description. The support structure of the transmission member 26 is provided with an elliptical retaining groove or retaining hole 263 for accommodating the positioning member 222. This embodiment uses a hole structure for description. After assembly, the positioning member 222 and the limiting hole 263 on the transmission member 26 have an assembly gap, and the two cooperate to limit the movement trajectory of the inner ring 211 during rotation, thereby preventing wire pressing. The limiting cooperation between the positioning member 222 and the limiting hole 263 on the transmission member 26 maintains the relative position of the pin 22 and the transmission member 26 within a certain range, so that the relative position of the end of the threading channel 2112 and the through hole 2124 of the quasi-spherical cabin 2123 also remains within a certain range. This avoids the problem of wire pressing caused by the pin 22 driving the inner ring 211 of the universal joint to rotate in one direction due to the lack of relative rotation restriction between the pin 22 and the transmission member 26.

[0102] It should be noted that the positioning member 222 and the limiting hole 263 on the transmission member 26 function only to limit their relative position and do not provide any transmission effect. The transmission structure between the transmission member 26 and the pin 22 will be described below. In addition, because the position of the elliptical hole on the transmission member 26 changes as the transmission member 26 rotates, the positioning member 222 is movable within the limiting hole 263 of the transmission member 26, and the two are not in a relatively fixed state.

[0103] To further prevent the wire 4 from being pressed between the inner ring 211 and the outer ring 212 of the universal joint, the width of the end opening of the wire passage 2112 aligned with the through hole 2124 gradually increases, thereby preventing wire compression during the rotation of the inner ring. To improve the stability and reliability of the wire passing through the wire passage 2112, the end of the wire passage 2112 connected to the second connector 25 is configured to gradually narrow in the direction closer to the connector.

[0104] In the above-mentioned spherical universal joint, referring to Figures 17-18, the spherical cabin body 2123 is configured to include at least a cabin body 21231 and an upper cover 21232. The upper cover 21232 covers the cabin body 21231 and encloses to form a accommodating space for accommodating the inner ring. The spherical cabin body 2123 is configured to be a coverable cabin body 21231 and an upper cover 21232 to form an accommodating space, which reduces the processing difficulty of the outer ring 212 of the universal joint and reduces the processing cost of the outer ring 212.

[0105] To further enhance the assembly stability between the cabin body 21231 and the upper cover 21232, the upper cover 21232 is equipped with an elastic member for applying an elastic force toward the cabin body 21231. The elastic member is preferably a spring, which is arranged vertically to apply downward pressure to the upper cover 21232. Alternatively, the spring can be arranged horizontally to apply pressure to the upper cover 21232 from the side, depending on actual needs.

[0106] 17-18 , the spherical cabin 2123 is relatively fixed to the first connecting member 24 , that is, it is fixed on the first connecting member 24 , or, referring to FIG. 20-21 , the outer wall of the outer ring 212 is provided with a third rotating shaft 2122 , and the third rotating shaft 2122 is hinged to the first connecting member 24 .

[0107] In the above arrangement of the wires 4, the bottom end of the wires 4 is located in the base 1. The wires 4 can draw power from the electrical components in the base, or a power supply device can be directly set in the base.

[0108] Since most of the structures of the electric air outlet component 3 and the swing head assembly 2 are driven by the pin 22, the pin 22 will deform during the actual rotation process, which increases the transmission resistance and causes the transmission process to jam. To this end, the bottom of the second connecting member 25 has an inclined portion 251, and the inclined portion 251 can be detachably connected or integrally formed at the bottom of the second connecting member 25, or the inclined portion 251 can be detachably connected or integrally formed at the bottom of the inner ring 211 of the universal joint, or the inner ring 211 of the universal joint or the second connecting member 25 is an integrally formed structure with the pin 22, and the inclined portion 251 is part of the integrally formed structure. One end of the pin 22 is fixedly connected to the inclined member 251, and the other end is slidably nested with the transmission member 26, thereby allowing the pin 22 to have the ability to move along the direction of its shaft. In the process of the second motor 23 driving the pin 22 to rotate through the transmission member 26, the pin 22 is slightly bent and deformed, and the pin 22 slides upward along the direction of its rod relative to the transmission member 26, thereby effectively alleviating the problem of increased resistance between the pin 22 and the inclined member 251 and the transmission member 26 due to the deformation of the pin 22, and jamming of the transmission process, thereby improving the transmission smoothness and efficiency.

[0109] As an embodiment, referring to FIG2 , the tilting member 251 is configured as a sleeve, and the top end of the pin 22 is embedded in the sleeve and fixed to each other by a locking structure. The locking structure can be a latch, a bolt, a riveted column, or an existing fixed connection method, which can be selected according to actual needs. A hole 261 is provided at one end of the transmission member 26 that is connected to the pin 22. The hole 261 can be slidably sleeved on the bottom end of the pin 22 to form a sliding nest. During the rotation of the transmission member 26, transmission is achieved through the cooperation between the hole 261 and the pin 22. The above configuration of the tilting member 251 as a sleeve and sleeves the pin 22 and fixedly connects the two is beneficial to improving the strength and rigidity of the pin 22 on the basis of achieving the connection between the two, making the pin 22 less likely to be deformed and increasing the service life of the pin 22. At the same time, it also reduces the deformation of the pin 22, making the transmission of the pin 22 smoother. A hole 261 is provided on the transmission member 26 for slidingly nesting with the pin 22, thereby solving the problem of large transmission resistance and jamming caused by deformation of the pin 22 during transmission. The structure is simple and easy to produce and assemble.

[0110] In another embodiment, referring to Figures 15 and 21, the tilting member 251 is also configured as a sleeve, and the top end of the pin 22 is embedded in the sleeve and fixed to each other by a locking structure. The end of the transmission member 26 connected to the pin 22 is provided with a supporting structure to support the bottom of the pin 22. Specifically, a spherical arm 221 is provided at the bottom end of the pin 22, and the above-mentioned positioning member 222 is provided below the spherical arm 221. The supporting structure is configured as a groove 262 (ball bowl groove), and the spherical arm 221 cooperates with the groove 262 to achieve transmission. When the pin 22 drives the electric air outlet component 3 to rotate through the transmission member 26, the pin 22 is deformed, and the pin 22 slides upward along its shaft relative to the transmission member 26, but the spherical arm 221 does not separate from the groove 262 of the transmission member 26, thereby solving the problems of large transmission resistance and transmission jamming, and also ensuring the transmission effect between the pin 22 and the transmission member 26. During the transmission process, the groove 262 and the spherical arm 221 are in rolling contact, and the contact area between the two is smaller than the solution of providing a hole 261 on the transmission member 26, the transmission resistance is smaller, and the transmission is smoother.

[0111] Among them, preferably, the groove 262 of the transmission member 26 is preferably hemispherical, which not only ensures the transmission between the transmission member 26 and the pin 22, but also greatly avoids the bottom end of the pin 22 from falling off the transmission member 26, and also facilitates the assembly between the pin 22 and the transmission member 26.

[0112] The connection between the pin 22 and the inclined member 251 can also be achieved by configuring the top end of the pin 22 as a sleeve, with the inclined member 251 embedded in the sleeve and secured to each other using a locking structure. Furthermore, the connection between the pin 22, the inclined member 251, and the transmission member 26 can also be achieved by sliding one end of the pin 22 into the inclined member 251 and the other end fixedly connected to the transmission member 26, thereby resolving the problems of high transmission resistance and jamming caused by deformation of the pin 22 during transmission.

[0113] In order to make the force applied to the swing head assembly 2 more uniform during the transmission process and improve the transmission effect, the center position of the universal joint 21 is located on the axis of the rotating shaft of the second motor 23, that is, on the line L1. In this way, no matter which working position the electric air outlet component 3 is located, the force it exerts on the swing head assembly 2 is basically the same, thereby improving the transmission efficiency.

[0114] In this embodiment, the rotating shaft of the turntable 13 and the rotating shaft of the second motor 23 are staggered, so that the first motor 12 and the second motor 23 can be staggered, thereby reducing the thickness of the base 1 and making the base 1 thinner.

[0115] Example 2

[0116] This embodiment adopts the three-dimensional rotating and swinging air outlet device for preventing electric wire winding of embodiment 1. On this basis, a shaking control method of the three-dimensional rotating and swinging air outlet device for preventing electric wire winding is provided, comprising:

[0117] Circularly controlling the first motor 12 to drive the turntable 13 to rotate forwardly around its rotation axis by a preset angle and then reversely reset, wherein the preset angle is configured between 1° and 360°;

[0118] During the rotation of the turntable 13 , the second motor 23 is continuously controlled to drive the pin 22 to rotate around its rotation axis.

[0119] The first motor 12 controls the rotation of the turntable 13, thereby driving the swing head assembly 2 and the electric air outlet component 3 to rotate as a whole, and the rotation angle is between 1°-360°. When it rotates 360°, the air outlet device can supply air to the surrounding area of ​​its position, and the air supply range is large. After the turntable 13 rotates 360°, it reverses, which can prevent the wires 4 from being entangled and causing damage to the wires 4, circuit failure, and safety issues in use. In the process of the first motor 12 driving the turntable 13 to rotate, the second motor 23 drives the electric air outlet component 3 to swing through the swing head assembly 2, which further increases the air supply range and makes the air supply more three-dimensional.

[0120] In actual use, the rotation directions of the turntable 13 and the oscillating head assembly 2 can be the same or opposite. Specifically, when the turntable 13 rotates forward, the oscillating head connecting rod rotates forward or reverse; when the turntable 13 rotates reverse, the oscillating head connecting rod rotates forward or reverse. The rotation speeds of the two can also be different or equal. In addition, the preset angle can be set to multiple levels, for example, the first level is 45°, the second level is 90°, the third level is 135°, etc., and the last level is the maximum angle.

[0121] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
