Description

Technical Field

[0001] The utility model relates to the field of refrigeration equipment, in particular to a fan. Background Art

[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.

[0004] Therefore, the utility model provides a fan. Utility Model Content

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

[0050] Continue to refer Figures 1 to 5In the fan of the utility model, a filter 12 and a fan 14 for generating an air flow in a vertical direction are arranged inside the base 1, a partial outer shell of the base is provided with a plurality of air inlets 11, the filter 12 is arranged upstream of the fan 14, and a circular air outlet of the fan 14 is arranged at the upper end of the base 1. The air guide sleeve 13 is sleeved on the air outlet, and the air guide sleeve 13 includes an inner tube portion 131 and an air distribution outer tube portion 132 which is liftably sleeved on the outer periphery of the inner tube portion 131, and a plurality of vents are distributed around the air distribution outer tube portion 132. The inner tube portion 131 and the air distribution outer tube portion 132 are a retractable double-layer sleeve structure. A plurality of through holes serving as vents are arranged around the air distribution outer tube portion 132. The desktop component 2 is connected to the central area surrounded by the annular air outlet at the upper end of the base 1, and covers the annular air outlet. The lower part of the desktop component 2 is provided with an annular guide slope 20 that guides the airflow emitted from the annular air outlet 15 in the horizontal circumferential direction. A circumferential diffusion air duct is formed between the annular guide slope 20 and the annular air outlet. When the air splitting outer pipe part 132 overlaps with the inner pipe part 131, the fan operates in the air purifier state. When the air splitting outer pipe part 132 rises based on the inner pipe part 131 and supports the annular guide slope 20, the air splitting outer pipe part 132 limits the air outlet area of ​​the circumferential diffusion air duct, and the fan operates in the fan state. The shape of the desktop component 2 is an inverted cone, and the annular air outlet surrounds the bottom surface of the inverted cone. The cone surface of the inverted cone forms an annular guide slope 20. The annular guide slope 20 guides the airflow emitted in the vertical direction through the annular air outlet to diffuse in the surroundings along the horizontal direction away from the central axis of the base 1. The cone surface is an annular concave arc surface, which can guide the vertical air flow to the horizontal direction. The lower edge of the annular concave arc surface is connected to the inner periphery of the annular air outlet, and the upper edge is suspended and extends to the outer periphery of the outer periphery of the annular air outlet. The upper surface 21 of the desktop component 2 is a coffee table or dining table for placing objects. The desktop component 2 is provided with a plurality of buttons 23 around it, and the buttons 23 are electrically connected to the fan 14. Figure 6 When the air distribution outer pipe portion 132 rotates horizontally based on the inner pipe portion 131, the air outlet direction of the vent changes based on the horizontal direction.

[0051] The present invention can change the working state of the fan by pushing up or pulling down the air-dividing outer pipe part 132. When the air-dividing outer pipe part 132 is pushed up and docked with the annular guide slope 20, the air flow emitted from the annular air outlet will be constrained and compressed by the annular guide slope 20 and the vent, so that the air flow must pass through the vent to leave the range of the air-dividing outer pipe part 132 and then continue to be guided by the part of the annular guide slope 20 outside the air-dividing outer pipe part 132. The compressed high-speed air diffuses in all directions based on the horizontal plane. When the air-dividing outer pipe part 132 is pulled down and overlapped with the inner pipe part 131, the air-dividing outer pipe part 132 no longer interferes with the circumferential diffusion air duct, and the outlet area is greatly increased, so that the inlet and outlet air flow speeds of the fan are basically the same, and the fan is operated in the fan state.

[0052] 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 the functions of an air purifier and a fan, providing multiple functions without sacrificing the interior space of a house, thereby expanding the use scenarios of bladeless fans.

[0053] 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.
