A filter 12 and a fan 13 for generating a vertical upward air flow are arranged inside the base 1, a partial housing of the base is provided with a plurality of air inlets 11, and the filter 12 is arranged upstream of the fan 13. The lower end of the air collecting pipe 14 is connected to the air outlet of the fan 13, and as the air flow moves in the air collecting pipe 14, the distance between the air flow and the air inlet 11 increases. The desktop component 2 is an inverted cone, and the annular slope 23 of the inverted cone is provided with a plurality of hidden inclined air outlets 26. The interior of the inverted cone is provided with a diversion duct 25 for guiding the air flow. The lower end of the diversion duct 25 is connected to the upper end of the air collecting pipe 14. The diversion duct 25 diverts multiple independent air ducts 24 from the lower end upward. The independent air ducts 24 are respectively connected to the hidden inclined air outlet 26. The air flow is guided along the diversion duct 25 to spread obliquely along the central axis away from the base 1 and to the surrounding areas of the bottom surface of the desktop component 2, so that the air flow can spread from a higher and wider air outlet to the surrounding areas, thereby accelerating the speed of purifying the indoor air. Furthermore, since the hidden inclined air outlet 26 is equivalent to being arranged on the bottom surface of the desktop component 2, the user cannot see the hidden inclined air outlet 26 at all when using it. The fan of the utility model fully displays the structure of the coffee table, and the air purifier is concealed into the furniture structure through the hidden air outlet design, which improves the integration of furniture and home appliances and optimizes the indoor space utilization.

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

[0050] Continue to refer Figures 1 to 3The fan base 1 of the utility model is provided with a filter 12 and a fan 13 for generating a vertical upward air flow. The partial shell of the base 1 is provided with a plurality of air inlets 11, and the filter 12 is arranged upstream of the fan 13. The lower end of the air collecting pipe 14 is connected to the air outlet of the fan 13. As the air flow moves in the air collecting pipe 14, the distance between the air flow and the air inlet 11 increases. The base 1 is a cylindrical base. 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 into the fan 13. The desktop component 2 is an inverted cone, and the annular slope 23 of the inverted cone is provided with a plurality of hidden inclined air outlets 26. The interior of the inverted cone is provided with a diversion duct 25 for guiding the air flow. The lower end of the diversion duct 25 is connected to the upper end of the air collecting pipe 14. The diversion duct 25 diverts multiple independent air ducts 24 from the lower end to the upper side. The independent air ducts 24 are respectively connected to the hidden inclined air outlet 26. Each independent air duct 24 is a pipeline providing an arc-shaped air guide path. As the air flow moves along the air collecting pipe 14, the smaller the cross-sectional area of ​​the air collecting pipe 14 is, the faster and more pressurized the air flow can be achieved. Among them, in order to achieve the concealed effect of the air outlet, the utility model sets the air outlet on the annular slope 23 of the inverted cone, but the direction of this air outlet will be close to the air inlet 11 of the base 1. Therefore, in order to maximize the distance between the hidden inclined air outlet 26 and the air inlet 11 in the height direction, a vertical air collecting pipe 14 is set, so that the air flow can move away from the bottom air inlet 11 as soon as possible after it is generated, and the height difference is widened to avoid the air short circuit caused by the height distance between the hidden inclined air outlet 26 and the air inlet 11 being too small. The hidden inclined air outlet 26 is located at the bottom of the annular slope 23, and the air flow is guided along the diverter duct 25 to spread obliquely along the central axis away from the base 1 and around the bottom surface of the desktop component 2, so that the air flow can spread from the higher and wider air outlet to the surroundings, which speeds up the purification of indoor air. The upper surface 22 of the desktop component 2 is a coffee table for placing objects. Since the hidden inclined air outlet 26 is equivalent to being set on the bottom surface of the desktop component 2, the user cannot see the hidden inclined air outlet 26 at all when using it. The fan of the utility model fully shows the structure of the coffee table. The air purifier is hidden and combined with the furniture structure through the hidden air outlet design, which improves the integration of furniture and home appliances and optimizes the indoor space utilization. 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. The air purifier is concealed into the furniture structure through a hidden air outlet design, thereby improving the integration of furniture and home appliances and optimizing the indoor space utilization.

[0052] 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.
