[0058] The specific implementation of the utility model includes:

[0059] Continue to refer Figures 1 to 5 The base 1 of the fan of the utility model is provided with a filter 12 and a fan 13 for generating a vertically rising air flow, a partial outer shell of the base is provided with a plurality of air inlets 11, the filter 12 is arranged upstream of the fan 13, and an annular sliding flange 15 is provided around the vertical air outlet 14 of the fan 13. The desktop component 2 includes a desktop body 20 and an air distribution guide 24. The vertical air inlet 27 at the lower end of the air distribution guide 24 is connected to the vertical air outlet 14 of the fan 13. A plurality of horizontal air outlets 26 are arranged in a circular manner on the upper part of the air distribution guide 24. A plurality of sub-air ducts 25 are formed inside the air distribution guide 24. The sub-air ducts 25 are connected to parts of the vertical air outlet 14 and the corresponding horizontal air outlets 26 respectively. The air flow is guided along the air distribution guide 24 to diffuse around in a horizontal direction away from the central axis of the base 1. An annular sliding groove 28 is arranged around the vertical air inlet 27. The annular sliding flange 15 is embedded in the annular sliding groove 28 and slides in an annular manner, driving the desktop component 2 to rotate to change the direction of the horizontal air outlet 26. The filter 12 is a cylindrical air filter. The outside air enters the base 1 from the air inlet 11, passes through the filter 12 radially, and is sucked in by the fan 13, but this is not limited to this. The upper surface 22 of the desktop component 2 is a coffee table for placing objects. The base 1 is a cylindrical base, and the desktop body 20 is a disc-shaped desktop, but not limited thereto. The diameter of the desktop body 20 is larger than the diameter of the air distribution guide 24, and the diameter of the upper part of the air distribution guide 24 is larger than the diameter of the base 1, thereby shielding the horizontal air outlet 26 of the air distribution guide 24, so that the user will not see the horizontal air outlet 26 when using it, and the air purifier can be hidden in the furniture structure, thereby improving the integration of furniture and home appliances and optimizing the indoor space utilization.

[0060] The fan of the utility model can change the direction of the horizontal air outlet 26 by the horizontal rotation of the desktop component 2 based on the base 1, so as to achieve air purification in all directions in the room. The vertical air outlet 14 of the base 1 is provided with a plurality of air dividing walls 16 along the radial direction, and the air dividing walls 16 divide the vertical air outlet 14 into a plurality of sub-air outlets 18, and each sub-air outlet 18 is connected to the corresponding sub-air duct 25 in the air dividing guide 24. The air dividing walls 16 intersect at the rotation axis of the fan 13, and the first contact 17 and the second contact 29 are both located at the rotation axis of the fan 13. The lower surface 23 of the desktop body 20 is connected to the top of the air dividing guide 24, and the desktop body 20 rotates synchronously with the air dividing guide 24.

[0061] However, two technical difficulties may occur during the rotation of the desktop component 2 relative to the base 1: conventional cables may be cut, making it impossible for the buttons set on the desktop component 2 to control the fan 13 in the base 1. In addition, during the rotation, the air flow easily passes through the gap between the annular sliding flange 15 and the annular sliding groove 28, causing the speed of the air flow to decrease. A button 21 is provided on the side of the desktop body 20 of the utility model, and a first contact 17 is provided in the center of the bottom surface of the button 21, and the button 21 is electrically connected to the first contact 17 through a cable. The base 1 is provided with a second contact 29, and the first contact 17 contacts with the second contact 29 to form an electrical connection, and the second contact 29 is connected to the fan 13 through a cable, so that during the rotation of the desktop component 2 by 360° based on the base 1, the button 21 can always ensure the electrical connection relationship with the fan 13, but it is not limited to this. Moreover, the surface of the annular sliding flange 15 and the surface of the annular sliding groove 28 are respectively provided with rubber sealing layers, and the rubber sealing layer of the annular sliding flange 15 and the rubber sealing layer of the annular sliding groove 28 fit together to form two annular sealing rings for docking and sealing, so that during the process of the desktop component 2 rotating 1360° based on the base, no air will leak from the gap between the annular sliding flange 15 and the annular sliding groove 28, thereby ensuring the air volume of the fan.

[0062] Since the overall shape of the utility model can be a coffee table, there is no need to store the fan or air purifier when it is not in use, and there is no need to occupy extra indoor space for the multifunctional bladeless fan.

[0063] In summary, the purpose of the utility model is to provide a fan that can have the functions of an air purifier, a fan and a desktop within a limited overall volume, and can flexibly adjust the wind direction of the air outlet, providing multiple functions without sacrificing the interior space of the house, thereby expanding the use scenarios of bladeless fans.

[0064] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. 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.
