[0031] Reference Figures 1 to 5 The utility model provides a hanging fan with filter function aims at providing more clean, healthy air environment for user, hanging fan includes three big core parts of casing 100, motor assembly 200 and filter assembly 300, and the three are connected through accurate structure, and the air supply and filter function of hanging fan are realized jointly.

[0032] Casing 100 is the main structure of hanging fan, not only bears motor assembly 200 and filter assembly 300, but also undertakes the important responsibility of protecting internal devices.Hoisting piece 110 is arranged at the upper end of casing 100, and hoisting piece 110 makes hanging fan can be conveniently installed at the position such as ceiling or mosquito net top, which is not only beautiful but also practical.Hoisting piece 110 is usually made of high-strength, corrosion-resistant material to ensure the stability and safety of hanging fan.

[0033] Motor assembly 200 is the power source of hanging fan, is connected at the lower end of casing 100, and wind is generated by driving the rotation of multiple fan blades 210.The selection of motor assembly 200 not only satisfies the power requirement of hanging fan, but also has the characteristics such as high efficiency, low noise and long service life.For example, motor assembly 200 can adopt advanced direct-current brushless motor technology, has the advantages such as high energy efficiency, stable operation and low noise.Motor assembly 200 can also be equipped with intelligent control system, and user can adjust speed parameters through remote controller or mobile phone APP.Casing 100 can be provided with light emitting components, and hanging fan has lighting function, and user can control the opening of light through remote controller or mobile phone APP.Fan blade 210 is one of the key components of hanging fan, and the selection of its shape, quantity and material directly affects the air volume and air pressure of hanging fan.The shape of fan blade 210 is optimized and designed, can reduce noise and energy consumption while ensuring air volume.

[0034] Filter assembly 300 is the innovation point of hanging fan, and filter assembly 300 is connected on casing 100 and has filter screen 310 above fan blade 210. Figure 2As shown, the projection of the filter screen 310 in the vertical direction can completely cover the rotation range of the fan blade 210, meaning that most of the air flow in the rotation range of the fan blade 210 first passes through the filter screen 310, thereby filtering out dust and particulate matters in the air. The filter screen 310 can adopt a multi-layer structure, including a primary filter screen 310, a medium filter screen 310 and a high-efficiency filter screen 310, etc., which can effectively filter out harmful substances such as dust and particulate matters in the air, thereby improving the cleanliness of the air. At the same time, the filter screen 310 also has the characteristics of being easy to disassemble and clean, and the user can regularly replace or clean the filter screen 310 as needed to obtain good filtering effect.

[0035] The ceiling fan with filtering function has the advantages of compact structure, reasonable design, efficient air filtering function in limited space, effective filtering of harmful substances such as dust and particulate matters in the air, and improved cleanliness and quality of the air. This innovative design not only provides a healthier and more comfortable use environment for users, but also reflects the pursuit of modern life quality. With the increasing attention to air quality and the continuous improvement of environmental protection awareness, the ceiling fan will undoubtedly become an ideal choice for future home life.

[0036] In some embodiments of the utility model, the outer diameter of the filter screen 310 is greater than or equal to the radius of rotation of the fan blade 210, and when the fan blade 210 rotates, the generated air flow can fully pass through the filter screen 310, thereby effectively filtering out dust, particulate matters and other impurities in the air.

[0037] Further, the filtering assembly 300 further comprises a bracket 320 connected to the housing 100, and the bracket 320 serves as a support structure for the filter screen 310. The bracket 320 is designed to be strong and durable, and can withstand the weight of the filter screen 310 and the air flow impact force generated when the fan blade 210 rotates. A plurality of connecting rods 321 are arranged on the bracket 320 in a circumferential direction, which ensures the stable installation and balanced stress of the filter screen 310. Moreover, the area of the connecting rod 321 is small, thereby minimizing the air flow resistance. The filter screen 310 is placed on the connecting rod 321, and through the support of the connecting rod 321, the filter screen 310 can maintain a stable position and is not easy to shake or fall off.

[0038] In order to further enhance the stability of the filter screen 310 and prevent it from falling off, an outer ring plate 322 is further arranged on the outer periphery of the plurality of connecting rods 321. The outer ring plate 322 is tightly connected with the connecting rod 321, forming a closed or semi-closed ring structure. The ring structure can effectively limit the position of the filter screen 310 and prevent it from being displaced or deformed under the action of air flow. At the same time, the design of the outer ring plate 322 also increases the overall aesthetics of the filtering assembly 300, making it more consistent with other parts of the ceiling fan.

[0039] In some embodiments of the utility model, the shell 100 adopts detachable design, including two parts of upper half shell 101 and lower half shell 102, not only convenient for the assembly and maintenance of ceiling fan, but also make the user more convenient and fast when replacing parts or cleaning. Upper half shell 101 and lower half shell 102 are connected through fastener or buckle, or other reliable connection mode, ensure the stability of shell 100.

[0040] Referring to Figure 3 In the shell 100, an installation cavity is formed for accommodating the electric control board 120 and battery assembly 130 of ceiling fan.

[0041] Referring to Figure 4 And Figure 5 In order to further improve the stability and reliability of operation button 103, upper half shell 101 is further connected with a button piece 140, and the button piece 140 as the carrier of operation button 103 is designed reasonably, so that the user can press the button easily and accurately. Operation button 103 is arranged on the surface of button piece 140, which is convenient for the user to operate. Upper half shell 101 is provided with through hole, so that button piece 140 passes through, so that the user can directly contact operation button 103 from the outside.

[0042] Further, in order to meet the connection requirement between button piece 140 and upper half shell 101, button piece 140 is provided with two supporting arms 141, and mounting ring 142 is arranged at the end of supporting arm 141. The mounting ring 142 is sleeved on the support column 104 of the inner wall of upper half shell 101, and the reliable connection between button piece 140 and upper half shell 101 is realized through the cooperation of mounting ring 142 and support column 104, and the button piece 140 can move in a small range by using supporting arm 141, which is convenient for the user to press operation button 103. Two supporting arms 141 can effectively prevent button piece 140 from loosening or falling off during use.

[0043] It can be understood that the mounting ring 142 and the support column 104 can adopt an interference fit. The interference fit is a commonly used connection method, which realizes close and firm connection by generating a certain interference between the fitting surfaces. In some embodiments, the mounting ring 142 is provided with a notch so as to be easily sleeved on the support column 104. When the mounting ring 142 is sleeved in place, due to the interference fit between the mounting ring 142 and the support column 104, the mounting ring 142 will closely fit on the support column 104 and is not easy to loosen or fall off, which not only improves the stability of the button piece 140, but also makes the overall structure of the ceiling fan more compact and reliable.
