[0002] Traditional fans usually include a motor, blades, a base or a fixing frame, a power supply, etc. When the power is turned on, the motor rotates, driving the blades on the motor shaft to rotate. The rotating blades generate airflow, so as the heat is taken away by convection and evaporation, the user feels the cooling effect within the range of the airflow.

[0003] However, due to the limitation of the working principle of the vertical impeller, the core component of a conventional cross-flow fan, the air is discharged in vertical strips, which makes the air outlet width based on the horizontal plane narrow, and it is difficult to obtain a wide air outlet range based on the horizontal plane; if the angle of the air outlet is simply diffused, the air pressure at the air outlet will decrease rapidly, the wind force will be significantly weakened, or a high-speed motor will be required, which increases noise.

[0004] Moreover, the function is single. Since the table fan occupies a large area of ​​the desktop, it forms a dilemma that multiple electrical appliances on the desktop each occupy a large area, and the desktop area that users can use is too small.

[0005] Therefore, the present invention provides a fan. Summary of the invention

[0006] In view of the problems in the prior art, the purpose of the present invention is to provide a fan that overcomes the difficulties of the prior art, can provide wireless charging for mobile phones, and switch control modes based on usage status, thereby saving desktop area for users and expanding usage scenarios.

[0063] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0064] Since fans, especially table fans, are relatively small in size, the buttons of table fans are arranged on a horizontal surface on the outer shell to adapt to the user's habit of vertical pressing. However, in order to set a wireless charging module on the flat horizontal surface of the table fan (usually a wireless charging module is a circle with a diameter of nearly 10 cm, which is a very large area for a table fan), it will conflict with the button area of ​​the fan. In addition, as mobile phones are getting bigger and bigger, the area of ​​the mobile phone is already the same as the bottom cross-sectional area of ​​the fan, which makes the mobile phone cover the button area, making the button area unusable when the mobile phone is magnetically wirelessly charged. In order to solve this technical problem, the present invention provides two modes of wired control and wireless control for automatic switching, thereby avoiding the technical difficulty that when the fan is combined with the wireless charging module, the mobile phone blocks the fan button and the fan cannot be controlled.

[0065] Figure 1 It is a schematic diagram of a first usage state of the fan of the present invention. Figure 2 for Figure 1 Cross-section along the AA direction. Figure 3 It is a side view of the fan of the present invention. Figure 4 This is a schematic diagram of module connection in a first usage state of the fan of the present invention. Figure 5 for Figure 4 A partial enlarged view of the . Figure 6 FIG. 2 is a top view of the upper surface of the lower edge of the fan of the present invention. Figures 1 to 6As shown, the fan of the present invention comprises: a frame-shaped housing 1, two cross-flow fans 11, a control module 43, a wireless module 44 and a power supply module 45. The frame-shaped housing 1 comprises a group of vertical opposite sides 31, an upper side 32 and a lower side 33 forming a hollow frame with a central through hole 10. The frame-shaped housing 1 defines an internal channel, and each of the vertical opposite sides 31 is provided with at least one air inlet 12 and at least one air outlet 13. A first annular magnetic attraction member 15 is provided at least on the upper surface and the lower surface of the lower side 33, respectively, and a button group 41 and a wireless charging coil 42 for charging a mobile phone are stacked in the first annular magnetic attraction member 15 on the upper surface 33A of the lower side 33, and the wireless charging coil 42 releases electromagnetic waves above the upper surface 33A of the lower side 33, so that the mobile phone can be placed on the upper surface 33A of the lower side 33 from the central through hole 10 for wireless charging. The two cross-flow fans 11 are respectively located in the internal channels of the vertical opposite sides 31. At least a second annular magnetic member 21 is provided on the upper surface of the support base 2 to be magnetically attracted to the first annular magnetic member 15. The crossflow fan 11 is placed downstream of the air inlet 12, and the impeller of the crossflow fan 11 rotates to draw air through the air inlet 12 into the internal channel, and at least a portion of the airflow is emitted from the air outlet 13. The power supply module 45 is respectively connected to the wireless charging coil 42, the control module 43 and the crossflow fan 11.

[0066] When in working state, the support base 2 supports the lower edge 33, and the second annular magnetic member 21 of the support base 2 is magnetically attracted to the first annular magnetic member 15 on the lower surface of the lower edge 33. The control module 43 is respectively connected to the wireless module 44 and the button group 41, the button group 41 is located in the annular area of ​​the first annular magnetic member 15, the button group 41 includes a first physical button 411, a second physical button 412, and a third physical button 413 exposed on the upper surface 33A of the lower edge 33, and the wireless charging coil 42 is located below the button group 41. The structure vertically arranges the button group 41 and the wireless charging coil 42 on the plane where the upper surface 33A of the lower edge 33 is located, and the button group 41 and the wireless charging coil 42 share the plane area defined inside the first annular magnetic member 15, and the wireless charging coil 42 can penetrate the button group 41 to charge the mobile phone. The control module 43 switches between a wired control state for receiving control information from the key group 41 or a wireless control state for receiving control information from the mobile phone when the mobile phone is placed on the wireless charging coil 42 for charging.

[0067] Figure 7 This is a schematic diagram of the fan of the present invention being used horizontally. Figure 7As shown, in a preferred example, the vertical opposite side portion 31, the upper side portion 32, and the lower side portion 33 are each provided with a first annular magnetic attraction member 15 on the outer periphery away from the central through hole 10, and the second annular magnetic attraction member 21 of the support seat 2 is magnetically attracted to any first annular magnetic attraction member 15 of the frame-type shell 1. After the second annular magnetic attraction member 21 of the support seat 2 is separated from the magnetic attraction assembly of the lower side portion 33, the second annular magnetic attraction member 21 on the upper surface of the support seat 2 is magnetically aligned with the first annular magnetic attraction member 15 on the outer side of the vertical opposite side portion 31 to achieve a horizontal use state, and the support seat 2 can still support the frame-type shell 1. At this time, the air outlet 13 of the fan extends along the horizontal line, and the air outlet width in the horizontal direction is greatly widened. Therefore, the present invention can change the extension direction of the air outlet 13 of the fan by changing the long side or short side of the support seat 2 and the frame-type shell 1 for magnetic attraction, thereby quickly switching between two different air outlet states, greatly enhancing the use scenario of the fan. In another preferred embodiment, the air outlet 13 is provided with a transverse air guide grille (not shown in the figure) and a longitudinal air guide grille (not shown in the figure), and the fan can be used with a dedicated remote control or a mobile phone remote control, but because the fan can be switched between vertical and horizontal positions, this will cause the actual functions of the transverse air guide grille and the longitudinal air guide grille used to control the wind direction of the air to be replaced. In order to overcome this technical problem, a motion detection sensor is also provided in the frame-type housing 1 of the present invention, which can detect the motion posture of the frame-type housing 1 relative to the horizontal axis. When it is detected that the frame-type housing 1 rotates 90° based on the horizontal axis, the first control signal for controlling the transverse air guide grille and the second control signal for controlling the longitudinal air guide grille can be automatically exchanged, so that the first control signal originally controlling the transverse air guide grille is applied to the longitudinal air guide grille, and the second control signal originally controlling the longitudinal air guide grille is applied to the transverse air guide grille. Therefore, when switching between vertical and horizontal positions, the control signals for the transverse air guide grille and the longitudinal air guide grille can also be switched in time, ensuring that the user's experience is not disturbed by the switching of the fan's use state (vertical use or horizontal use).

[0068] Figure 8 It is a schematic diagram of the second use state of the fan of the present invention. Fig. 9 This is a schematic diagram of module connection in the second use state of the fan of the present invention. Fig.10 The top view of the upper surface of the lower edge of the fan of the present invention is used to charge a mobile phone. Fig.11 The figure is a schematic diagram showing virtual buttons on a mobile phone placed under the fan of the present invention. Figures 8 to 11As shown, when the wireless charging coil 42 detects that the mobile phone 5 is placed thereon for wireless charging (at this time the mobile phone 5 has covered the button group 41, and the button group 41 cannot be used), the wireless module 44 will be triggered to actively communicate with the mobile phone 5. At this time, the control module 43 no longer receives the control information of the button group 41. The control module 43 actively establishes communication with the mobile phone 5, converts from wired control to receiving control information from the mobile phone 5 through wireless communication, and displays a preset interface containing multiple virtual buttons 511, 512, and 513 on the screen of the mobile phone 5, which can be used to control the fan by operating the virtual buttons. In this embodiment, each virtual button corresponds to a physical button, the virtual button 511 corresponds to the first physical button 411, the virtual button 512 corresponds to the second physical button 412, and the virtual button 513 corresponds to the third physical button 413, thereby ensuring that even if the physical buttons are blocked, the fan can be wirelessly controlled through the virtual buttons 511, 512, and 513 on the mobile phone 5.

[0069] Fig.12 It is a schematic diagram of the fan frame housing and the support base of the present invention in a state of being assembled and stored after being disassembled. Fig.13 FIG. 2 is a schematic diagram of the fan of the present invention in a stored state. Fig.12 , 13 As shown, the present invention further combines the magnetic suction component of magnetic wireless charging, and provides a technical effect that after the frame-type shell 1 is separated from the support seat 2, the support seat 2 is inserted into the central through hole 10 of the frame-type shell 1, and the second annular magnetic suction member 21 of the support seat 2 is magnetically limited with the first annular magnetic suction member 15 of the frame-type shell 1, so as to reduce the overall volume and facilitate the transportation of the storage box. When in the storage state, the support seat 2 is inserted into the central through hole 10, and the second annular magnetic suction member 21 of the support seat 2 is magnetically attracted with the first annular magnetic suction member 15 on the upper surface of the lower edge 33. It also realizes the reuse of the first annular magnetic suction member 15 on the upper surface of the lower edge 33. When the fan is working, it can be used for magnetic wireless charging of the mobile phone 5. In the storage state, the second annular magnetic suction member 21 of the support seat 2 can be magnetically attracted to limit the support seat 2 in the central through hole 10 of the frame-type shell 1, providing a storage auxiliary limit function.

[0070] In a preferred example, the lower surface of the upper edge portion 32 and the upper surface of the lower edge portion 33 of the inner circumference of the frame-shaped shell 1 are both provided with a first annular magnetic component 15, and the upper surface and lower surface of the support seat 2 are also provided with a second annular magnetic component 21, so that when in the storage state, the second annular magnetic component 21 on the upper surface of the support seat 2 is magnetically aligned with the first annular magnetic component 15 on the lower surface of the upper edge portion 32 of the inner circumference of the frame-shaped shell 1, and the second annular magnetic component 21 on the lower surface of the support seat 2 is magnetically aligned with the first annular magnetic component 15 on the upper surface 33A of the lower edge portion 33 of the inner circumference of the frame-shaped shell 1, thereby enhancing the magnetic attraction strength between the support seat 2 and the frame-shaped shell 1, and preventing the support seat 2 from slipping out of the central through hole 10 of the frame-shaped shell 1.

[0071] In a preferred example, the frame-type shell 1 includes a front shell and a rear shell connected to each other, the cavity formed by the front and rear shells forms an internal channel, the air inlet 12 is located on the rear shell, and the air outlet 13 is located at least on the front shell, the area of ​​the air inlet 12 is larger than the area of ​​the air outlet 13, and the impellers of the cross-flow fan 11 have the same rotation speed and opposite rotation directions, but are not limited to this.

[0072] In a preferred example, a filter and a heating device are provided in the frame-shaped shell 1, the filter is located downstream of the air inlet 12 and between the air inlet 12 and the cross-flow fan 11, and the heating device is located upstream of the air outlet 13 and between the air outlet 13 and the cross-flow fan 11, but it is not limited to this.

[0073] In a preferred example, the first annular magnetic member 15 and the second annular magnetic member 21 are annular magnets of the same size, but the present invention is not limited thereto.

[0074] In summary, the purpose of the present invention is to provide a fan that can provide wireless charging for a mobile phone, and switch the control mode in combination with the usage status, thereby saving desktop area for users and expanding the usage scenarios. In addition, the present invention solves the problem that the mobile phone blocks the button and cannot control the fan. By switching to wireless control, the influence of mobile phone wireless charging on fan control is avoided.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
