The utility model realizes the combination of household appliances and furniture by integrating the air purifier and the fan into the space volume of a conventional coffee table (the appearance of the utility model can be a round coffee table shape). In addition, since coffee table furniture is usually placed against a wall or a corner, there are multiple dead corners for air outlet. The air outlet needs to avoid the direction of these walls to improve the effectiveness of the fan or air purification, and flexibly switch multiple independent air outlet directions to adapt to different placement positions in the room, thereby enhancing the use effect of the fan.

[0042] In a preferred embodiment, the second through hole is located at the center of the upper surface of the first air duct 24 , and the first through hole is located between the second through hole and the edge of the upper surface of the first air duct 24 , but not limited thereto.

Of course, in a variation, the number of air guide covers, air outlets, and sleeve structures can be further increased to form a multi-layer concentric circle sleeve structure, thereby providing more independent air outlets, but the present invention is not limited thereto.

[0045] In a preferred embodiment, the combination of the outer sleeve 28 and the inner sleeve 27 jointly separates the air flow generated by the fan 13 to obtain a first sub-air flow and a second sub-air flow, the first sub-air flow enters the first air guide cover 24, and the second sub-air flow enters the second air guide cover 29, but is not limited to this.

[0046] In a preferred embodiment, the first air outlet 26 and the second air outlet 25 can each independently rotate 360° with the rotation axis of the fan 13 as the rotation center, but the present invention is not limited thereto.

[0047] In a preferred embodiment, the lower surface 23 of the desktop body 20 is connected to the upper surface of the first air outlet 26, and a gap is formed between the lower surface 23 of the desktop body 20 and the upper surface of the second air outlet 25, but this is not limited thereto.

[0048] In a preferred embodiment, the lower surface 23 of the desktop body 20 is connected to the upper surface of the second air outlet 25, and a gap is formed between the lower surface 23 of the desktop body 20 and the upper surface of the first air outlet 26, but this is not limited thereto.

[0049] The specific implementation of the utility model includes:

[0050] Continue to refer Figures 1 to 4 The base 1 of the fan of the utility model is provided with a filter 12 and a fan 13 for generating air flow inside, and a partial shell of the base is provided with a plurality of air inlets 11, and the filter 12 is arranged upstream of the fan 13. The desktop component 2 includes a desktop body 20, a first air guide cover 24 and a second air guide cover 29. The lower end of the first air guide cover 24 is rotatably connected to the air outlet of the fan 13, and the upper end of the first air guide cover 24 is provided with a first through hole and a second through hole, and the first through hole is connected to a first air outlet 26, and the air flow entering the first air guide cover 24 is emitted by the first air outlet 26, and the lower end of the second air guide cover 29 is rotatably connected to the second through hole, and the upper part of the second air guide cover 29 is provided with a second air outlet 25, and the air flow entering the second air guide cover 29 is emitted by the second air outlet 25. The desktop body 20 is a round plate, and a button 21 is provided on the side wall surface of the round plate, and the button 21 is connected to the fan 13. The upper surface 22 of the desktop component 2 is a coffee table top for placing items. The utility model realizes the combination of household appliances and furniture by integrating the air purifier and the fan into the space volume of a conventional coffee table (the appearance of the utility model can be a round coffee table shape). In addition, since coffee table furniture is usually placed against a wall or a corner, there are multiple dead corners for air outlet. The air outlet needs to avoid the direction of these walls to improve the effectiveness of the fan or air purification, and flexibly switch multiple independent air outlet directions to adapt to different placement positions in the room, thereby enhancing the use effect of the fan.

[0051] In this embodiment, the second through hole is located at the center of the upper surface of the first air duct 24 , the first through hole is located between the second through hole and the edge of the upper surface of the first air duct 24 , and the center of the second through hole passes through the rotation axis of the fan 13 . The first air guide cover 24 also includes an outer sleeve 28 with an inner shoulder, and the outer sleeve 28 surrounds the second through hole. The second air guide cover 29 also includes an inner sleeve 27, which is rotatably inserted into the outer sleeve 28 and supported by the inner shoulder of the outer sleeve 28. The combination of the outer sleeve 28 and the inner sleeve 27 jointly separates the air flow generated by the fan 13 to obtain a first sub-air flow and a second sub-air flow. The first sub-air flow enters the first air guide cover 24, and the second sub-air flow enters the second air guide cover 29. The first air outlet 26 and the second air outlet 25 each independently rotate 360° with the rotation axis of the fan 13 as the rotation center. The present invention can obtain multiple sub-air flows by using the air flow generated by the fan 13 as the wall of the wind chamber based on the annular nested sleeves, and each sub-air flow is emitted to its respective target direction through the air outlet that can be independently horizontally rotated based on the base 1. The lower surface 23 of the desktop body 20 is connected to the upper surface of the first air outlet 26, and a gap is formed between the lower surface 23 of the desktop body 20 and the upper surface of the second air outlet 25; or, the lower surface 23 of the desktop body 20 is connected to the upper surface of the second air outlet 25, and a gap is formed between the lower surface 23 of the desktop body 20 and the upper surface of the first air outlet 26.

[0052] refer to Figure 3 When the first air outlet 26 and the second air outlet 25 of the present invention are separated from each other, the fan can emit the purified air flow to the wide indoor space in the largest range. However, since the present invention is in the form of a coffee table, when the coffee table is placed against a corner, there may be a problem such as Figure 3 The second air outlet 25 in the fan blows air toward the wall, which obviously reduces the effect of the fan and the effective delivery of the purified air flow.

[0053] refer to Figure 3 and 4 At this time, the second air outlet 25 facing the wall can be rotated so that the second air outlet 25 is no longer facing the wall, thereby achieving effective air volume emitted by the fan and effective delivery of the purified air flow, so that the delivery of the air flow of the fan in the utility model is no longer restricted by the placement position. In addition, 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 additional indoor space for the multifunctional bladeless fan.

[0054] 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 switch between multiple independent air outlet directions to adapt to different placement positions in the room, thereby enhancing the use effect of the fan.

[0055] 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.
