In this embodiment, the upper surface 21 of the desktop component 2 is a coffee table desktop or a dining table desktop for placing objects, and a plurality of buttons 22 are arranged around the desktop component 2. The utility model integrates an air purifier and a fan within the space volume of a conventional coffee table (the appearance of the utility model can be the shape of a round coffee table), thereby realizing the combination of household appliances and furniture. It has the functions of an air purifier, a fan and a desktop within a limited overall volume, and can greatly adjust the direction of the air flow sprayed from each nozzle. It is flexibly applicable to various positions in the room, provides multiple functions without sacrificing the internal space of the house, and expands the use scenarios of the bladeless fan.

[0046] In a preferred embodiment, the annular air guide 3 includes a plurality of cylindrical nozzle cavities 35, which are distributed on the top surface of the annular cavity 34. The first opening 38 of the nozzle cavity 35 is connected to the annular cavity 34. The central axis of the nozzle cavity 35 is a horizontal axis. The nozzle 31 is rotatably connected to the nozzle cavity 35, so that the nozzle 31 can be pitched and adjusted after rotation to change the emission angle of the air flow, but this is not limited to this.

[0047] In a preferred embodiment, the annular air guide 3 further includes a cover shell 36 , which circumferentially covers the air guide body. The cover shell 36 is provided with a plurality of windows 37 , and the nozzles 32 correspond to the windows 37 , but the present invention is not limited thereto.

[0048] In a preferred embodiment, the first end of the nozzle 31 extends into the second opening 39 of the nozzle cavity 35 to receive the air flow, and arc-shaped clamps 33 are respectively provided on both sides of the first end and cooperate with the inner circumference of the nozzle cavity 35 to guide the nozzle 31 to rotate based on the inner circumference of the nozzle cavity 35, and the second end of the nozzle 31 forms a nozzle 32 extending out of the nozzle cavity 35. With the rotation of the nozzle 31, the nozzle 31 has a launch state extending out of the window 37 and a storage state stored in the housing 36. When in the launch state, the arc-shaped clamp 33 avoids the first opening 38 of the nozzle cavity 35, so that the nozzle cavity 35 is connected with the nozzle 32. When in the storage state, the arc-shaped clamp 33 blocks the first opening 38 of the nozzle cavity 35, so that the nozzle cavity 35 and the nozzle 32 are cut off. The utility model can realize switching between the launching state and the storage state by rotating the angle of the nozzle 31. In the launching state, the nozzle 31 can extend out of the window 37 to launch the air flow in the nozzle cavity 35. In the storage state, the nozzle 31 not only retracts into the window 37, but also can block the first opening 38 of the nozzle cavity 35 through the arc-shaped clamping plate 33, thereby cutting off the nozzle 31 and the annular cavity 34, allowing the air flow to be launched from the nozzles 31 in other launching states, thereby realizing the adjustment of the air flow intensity of different nozzles 31.

[0049] In a preferred embodiment, a plurality of sensors are also included, which are respectively connected to the fan 13. The sensors detect the posture of each nozzle 31 in the nozzle cavity 35 to obtain the working state of the nozzle 31, and as the number of nozzles 31 in the emitting state increases, the rotation speed of the driving fan 13 increases; when the number of nozzles 31 in the storage state increases, the rotation speed of the driving fan 13 decreases, but not limited to this.

[0050] In a preferred embodiment, a damping layer is provided on the surface of the arc-shaped clamping plate 33, and the damping layer is in surface contact with the inner circumference of the nozzle cavity 35, providing rotational damping to the nozzle 31 for rotation with the central axis of the corresponding nozzle cavity 35 as the rotation axis, so as to limit the direction of the air flow emitted by the nozzle 31, but not limited to this.

[0051] In a preferred embodiment, the annular air guide member 3 is connected to the base 1 , and the air outlet of the fan 13 is connected to the annular cavity 34 , but the present invention is not limited thereto.

[0052] The specific implementation of the utility model includes:

[0053] Continue to refer Figures 1 to 4The upper surface 21 of the desktop component 2 of the fan of the utility model is a coffee table desktop for placing things, so that the utility model can be used as a coffee table. The base 1 of the fan is provided with a filter 12 and a fan 13 for generating air flow inside, and the 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 annular air guide 3 is connected to the upper end of the base 1, and the annular air guide 3 includes an air guide body forming an annular cavity 34 and a plurality of nozzles 31 rotating based on a horizontal axis. The annular cavity 34 is arranged downstream of the fan 13 to receive the vertical air flow generated by the fan 13. The nozzles 31 are respectively connected to the outer periphery of the annular cavity 34, and the nozzles 31 guide the direction of the air flow (for example: guide the vertical air flow to an angle close to the horizontal direction) and then emit it to the surroundings. The desktop component 2 is connected to the top surface of the annular air guide 3. A plurality of buttons 22 are arranged around the desktop component 2. The annular air guide 3 includes a plurality of cylindrical nozzle cavities 35 and a cover 36. The nozzle cavities 35 are distributed on the top surface of the annular cavity 34. The first opening 38 of the nozzle cavity 35 is connected to the annular cavity 34. The central axis of the nozzle cavity 35 is a horizontal axis. The nozzle 31 is rotatably connected to the nozzle cavity 35, so that the nozzle 31 can be adjusted in pitch after rotation to change the emission angle of the air flow. The cover 36 circumferentially covers the air guide body. The cover 36 is provided with a plurality of windows 37, and the nozzles 32 correspond to the windows 37 respectively. The annular air guide 3 is connected to the base 1, and the air outlet of the fan 13 is connected to the annular cavity 34. The surface of the arc-shaped clamping plate 33 is provided with a damping layer, which is in surface contact with the inner circumference of the nozzle cavity 35, and provides the nozzle 31 with rotation damping for rotating with the central axis of the corresponding nozzle cavity 35 as the rotation axis, so as to limit the direction of the air flow emitted by the nozzle 31. The first end of the nozzle 31 extends into the second opening 39 of the nozzle cavity 35 to receive the air flow. The arc-shaped clamping plates 33 are respectively arranged on both sides of the first end and cooperate with the inner circumference of the nozzle cavity 35 to guide the nozzle 31 to rotate based on the inner circumference of the nozzle cavity 35. The second end of the nozzle 31 forms a nozzle 32 extending out of the nozzle cavity 35. With the rotation of the nozzle 31, the nozzle 31 has a launch state extending out of the window 37 and a storage state stored in the housing 36. When in the launch state, the arc-shaped clamping plate 33 avoids the first opening 38 of the nozzle cavity 35, so that the nozzle cavity 35 is connected with the nozzle 32. When in the storage state, the arc-shaped clamping plate 33 blocks the first opening 38 of the nozzle cavity 35, so that the nozzle cavity 35 and the nozzle 32 are cut off. In addition, the utility model also includes a plurality of sensors (not shown in the figure), which are respectively connected to the fan 13. The sensors detect the posture of each nozzle 31 in the nozzle cavity 35 to obtain the working state of the nozzle 31. When the fan of the utility model is used as an air purifier, as the number of nozzles 31 in the emitting state increases, the speed of the driving fan 13 increases; when the number of nozzles 31 in the storage state increases, the speed of the driving fan 13 decreases to ensure the air purification effect.The utility model can realize the switching between the emission state and the storage state of each nozzle 31 by rotating the angle of the nozzle 31. When the nozzle 31 is rotated so that the nozzle 31 extends out of the window 37, the fan is in the emission state, and the air flow in the nozzle cavity 35 is emitted around. When the rotating nozzle 31 retracts into the window 37 (the nozzle 31 is completely stored in the cover shell 36, and the appearance of the utility model is exactly the same as a common coffee table), when the fan is in the storage state, the first opening 38 of the nozzle cavity 35 can be completely covered by the arc-shaped card plate 33 (the structural function of the arc-shaped card plate 33 can be reused, which can not only provide rotational damping in the rotation stroke in the storage state, but also act as a pipeline valve in the storage state). At this time, the damping layer on the surface of the arc-shaped card plate 33 can also act as a sealing layer. The fitting trajectory of the damping layer and the edge of the first opening 38 forms a combined structure similar to a sealing ring surrounding the gap between the first opening 38 and the arc-shaped card plate 33, ensuring that the nozzle 31 is cut off from the annular cavity 34, allowing the air flow to be emitted from the nozzles 31 in other emission states, thereby realizing independent adjustment of the working state of each nozzle 31 and adaptive adjustment of the air flow intensity of the remaining nozzles 31.

[0054] When the utility model is used as a coffee table, the coffee table may be placed in the center of the living room, or may be placed against the wall on one side or both sides. Obviously, the air flow does not need to be emitted in the direction of the wall (to avoid wasting the air flow on the side facing the wall). Therefore, by rotating the nozzle 31 on the side facing the wall to the storage state, the annular cavity 34 can be used to distribute the air flow to other nozzles 31 to achieve effective use of the air flow. Since the overall shape of the utility model can be a coffee table, the fan or air purifier does not need to be stored when it is not in use, and there is no need to occupy extra indoor space for the multifunctional bladeless fan.

[0055] 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 greatly adjust the direction of the air flow ejected from each nozzle, so that it can be flexibly applied to various locations in the room, thereby expanding the use scenarios of bladeless fans.

[0056] 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.
