Figures 1 to 6As shown, the fan of the utility model comprises: a base 1, an air distribution guide 2 and a desktop air door cap 3. A filter 12 and a fan 13 for generating a vertical upward air flow are arranged inside the base 1, 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 air distribution guide 2 is a disc body, and the interior of the air distribution guide 2 is hollow to form a diversion air duct 24 for diverting and guiding the air flow from the bottom center to the upper periphery, and the outer peripheral wall of the disc body is provided with a plurality of horizontal air outlets 25, and the lower end 26 of the diversion air duct 24 is connected to the vertical air outlet 14 of the fan 13, and the upper end of the diversion air duct 24 is connected to the horizontal air outlet 25 respectively. The desktop damper cap 3 includes a disc desktop 31 and a cylindrical side wall 33 connected to the lower edge of the disc desktop 31. The cylindrical side wall 33 is provided with a plurality of vents 32 in the circumference. The disc desktop 31 can rotatably cover the upper surface of the wind distribution guide 2. The cylindrical side wall 33 covers the outer circumference of the wind distribution guide 2. As the disc desktop 31 rotates, the horizontal air outlet 25 blows outward only when it is from the vent 32. The utility model can block the blowing state of the fan by rotating the desktop damper cap 3. Therefore, it is no longer necessary to set any buttons on the outside of the desktop damper cap 3 used as a desktop. This also makes the fan of the utility model more similar to the appearance structure of a traditional desktop or coffee table, and can be placed and used as furniture, which greatly enhances the integration of furniture and home appliances and optimizes the indoor space.

The guiding wind direction of the horizontal sub-air duct 242 is parallel to the horizontal plane, but is not limited to this.

[0054] In a preferred embodiment, in the horizontal sub-air duct 242, the closer to the horizontal air outlet 25, the smaller the cross-sectional area of ​​the horizontal sub-air duct 242 is, but not limited thereto.

[0055] In a preferred embodiment, the filter 12 is a cylindrical air filter, and the outside air enters the base 1 from the air inlet 11, radially passes through the filter 12, and is sucked into the fan 13, but the present invention is not limited thereto.

[0056] In a preferred embodiment, the horizontal air outlets 25 are each located at the top of the outer peripheral wall, and the height of the horizontal air outlets 25 is greater than the height of the vertical air outlets 14, but not limited thereto.

[0057] In a preferred embodiment, the base 1 is a cylindrical base, but not limited thereto.

[0058] In a preferred embodiment, the upper surface 22 of the air distribution guide 2 is a tabletop of a dining table or a coffee table for placing objects, but is not limited thereto.

[0059] The specific implementation of the utility model includes:

[0060] Continue to refer Figures 1 to 3The base 1 of the fan of the utility model is provided with a filter 12 and a fan 13 for generating a vertical upward air flow. A partial shell of the base is provided with a plurality of air inlets 11. The filter 12 is arranged upstream of the fan 13. The wind dividing guide 2 is a disc body. The inside of the wind dividing guide 2 is hollow to form a diversion air duct 24 for diverting and guiding the air flow from the bottom center to the upper periphery. The outer peripheral wall of the disc body is provided with a plurality of horizontal air outlets 25. The lower end 26 of the diversion air duct 24 is connected to the vertical air outlet 14 of the fan 13, and the upper end of the diversion air duct 24 is connected to the horizontal air outlet 25 respectively. The desktop damper cap 3 includes a disc desktop 31 and a cylindrical side wall 33 connected to the lower edge of the disc desktop 31. The cylindrical side wall 33 is provided with a plurality of vents 32 in the circumference. The disc desktop 31 can rotatably cover the upper surface of the air distribution guide 2. The cylindrical side wall 33 covers the outer circumference of the air distribution guide 2. As the disc desktop 31 rotates, air is blown outward only when the horizontal air outlet 25 is from the vent 32. The base 1 is a cylindrical base, and the upper surface 22 of the air distribution guide 2 is a coffee table desktop for placing objects. As the disc desktop 31 rotates based on the air distribution guide 2, when the vent 32 is connected to the horizontal air outlet 25, an air outlet duct for blowing air outward is formed together. Alternatively, when the cylindrical side wall 33 blocks the horizontal air outlet 25, the air outlet duct is blocked. The inner wall of the cylindrical side wall 33 is provided with a first electronic contact 34, and the outer periphery of the wind distribution guide 2 is provided with a second electronic contact 27 connected to the fan 13. When the vent 32 is connected to the horizontal air outlet 25, the first electronic contact 34 contacts the second electronic contact 27, causing the fan 13 to rotate. When the vent 32 is blocked by the rotating cylindrical side wall 33, the first electronic contact 34 separates from the second electronic contact 27, and the fan 13 stops rotating. The utility model can detect the rotation state of the disc tabletop 31 according to the electrical connection state of the first electronic contact 34 and the second electronic contact 27. When the first electronic contact 34 is detected to be in contact with the second electronic contact 27, it means that the vent 32 is connected to the horizontal air outlet 25 to form an outlet duct for blowing air outward. At this time, the fan 13 works to blow out purified air or high-speed air flow, which can be used as an air purifier or a fan. The air flow is guided along the diversion duct 24 to the horizontal direction away from the central axis of the base 1 and then diffuses from the outlet duct to the surroundings. When the first electronic contact 34 is detected to be separated from the second electronic contact 27, the vent 32 is blocked by the rotating cylindrical side wall 33, and the fan 13 stops rotating, and it is completely used as a coffee table.

[0061] In addition, the diversion air duct 24 includes a plurality of guiding sub-air ducts 241 and a horizontal sub-air duct 242. The guiding sub-air duct 241 is an arc-shaped air duct. The first end of each arc-shaped air duct is arranged at the center of the lower surface 21 of the air diversion guide 2 and is connected to a part of the vertical air outlet 14. The second end of the arc-shaped air duct is connected to the first end of the horizontal sub-air duct 242. The second end of the horizontal sub-air duct 242 is a horizontal air outlet 25. The guiding wind direction of the horizontal sub-air duct 242 is parallel to the horizontal plane. In the horizontal sub-air duct 242, the closer to the horizontal air outlet 25, the smaller the cross-sectional area of ​​the horizontal sub-air duct 242 is, so as to enhance the strength of the air flow of the air outlet. 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. The horizontal air outlets 25 are each located at the top of the outer peripheral wall, and the height of the horizontal air outlet 25 is greater than the height of the vertical air outlet 14. For users, although the horizontal air outlet 25 in the utility model can be blocked and no external buttons are required, the overall shape of the utility model can be a coffee table, so 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.

[0062] 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. The overall structure is the same as a traditional dining table or coffee table, which greatly improves the integration of furniture and home appliances, optimizes the indoor space, and speeds up the purification of indoor air.
