[0002] At present, bladeless fans with air purification function have been increasingly used, but bladeless fans with more functions (air purification + fan) will inevitably lead to a larger overall volume, so that a floor-standing whole machine structure is usually adopted.

[0003] However, neither air purifiers nor fans are commonly used appliances every day. When not in use, the large volume of multifunctional bladeless fans (large floor-standing complete machine, the floor area of ​​the complete machine is close to 0.4 square meters) will take up extra indoor space, which is a great loss for the effective internal space of the room. Especially for users of small apartments, they will not choose multifunctional bladeless fans that occupy too much space and are difficult to store, which also restricts the promotion of bladeless fans with air purification functions, making it difficult for small-sized users to enjoy the convenience of multifunctional bladeless fans, and compressing the use scenarios of bladeless fans.

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

[0050] Continue to refer Figures 1 to 3 The 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, and the filter 12 is arranged upstream of the fan 13. The filter 12 is a cylindrical air filter, and the outside air enters the base 1 from the air inlet 11, passes through the filter 12 radially, and is sucked into the fan 13. The desktop component 2 is a disc body, and the upper surface 22 of the desktop component 2 is a coffee table or dining table for placing objects. The inner hollow of the disc body is formed from the bottom center, and a diversion duct 24 is formed to divert and guide the air flow to the upper surroundings. The outer peripheral wall 26 of the disc body is provided with a plurality of horizontal air outlets 25. The lower end of the diversion duct 24 is connected to the vertical air outlet 14 of the fan 13, and the upper ends of the diversion duct 24 are respectively connected to the horizontal air outlets 25. The air flow is guided along the diversion duct 24 to diffuse in the surroundings along the horizontal direction away from the central axis of the base 1, so that the air flow can diffuse in the surroundings from the higher and wider air outlets, thereby strengthening the purification function of the air purifier. The structure based on the coffee table or desktop greatly enhances the delivery capacity of the purified air. 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 connected to a part of the vertical air outlet 14, and 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, and 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 area of ​​the cross section of the horizontal sub-air duct 242, thereby achieving the effect of collecting wind and accelerating the speed of the air flow. The horizontal air outlets 25 are each located at the top of the peripheral wall 26 to increase the position of the air outlet, avoid forming an air short circuit with the air inlet 11 of the base 1, and enhance the effect of air purification. The button 21 is arranged on the surface of the peripheral wall 26, and the button 21 is connected to the fan 13 through a cable. For the user, although the horizontal air outlet 25 in the utility model is directly visible, the positive benefit brought is that the performance of the fan and the air purification performance are greatly enhanced. 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.

[0051] 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, greatly reducing the usage restrictions of large bladeless fans with air purifiers, improving the integration of furniture and home appliances, optimizing indoor space, and speeding up the purification of indoor air.
