[0020] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of a portable fan according to an embodiment of this application. Figure 2 This is a schematic diagram of the air outlet 100 according to an embodiment of this application. Figure 3 This is a schematic diagram of the charging unit 200 according to an embodiment of this application. The portable fan includes a detachably connected air outlet 100 and a charging unit 200. The air outlet 100 includes a first connecting component 11, and the charging unit 200 includes a second connecting component 21. When the second connecting component 21 is connected to the first connecting component 11, the air outlet 100 and the charging unit 200 are connected, and when the second connecting component 21 is separated from the first connecting component 11, the air outlet 100 and the charging unit 200 are separated.

[0021] The air outlet 100 also includes a housing 13 and a first terminal 12, and the charging unit 200 also includes a second terminal 22. The first terminal 12 is disposed on the housing 13, and the second terminal 22 is disposed on the first surface 23 of the charging unit 200. The first surface 23 is adapted to the outer peripheral surface of the housing 13. The adaptation is manifested in that the curvature of the first surface 23 and the outer peripheral surface of the housing 13 are approximately the same, so as to achieve surface-to-surface mating. When the first connecting assembly 11 and the second connecting assembly 21 are connected, the first surface 23 is adapted to the outer peripheral surface of the housing 13. For example, the first surface 23 is tightly fitted to the outer peripheral surface of the housing 13, or there is a small gap between the first surface 23 and the outer peripheral surface of the housing 13, and the first terminal 12 and the second terminal 22 are electrically connected to enable the charging unit 100 to charge the air outlet 100.

[0022] It is understood that the first terminal 12 is disposed on the housing 13, including but not limited to the first terminal 12 protruding from the housing 13, and the second terminal 22 is disposed on the first surface 23 of the charging part 200, including but not limited to the second terminal 22 protruding from the first surface 23. Alternatively, one of the first terminal 12 or the second terminal 22 may protrude from the surface while the other is recessed from the surface, as long as the first terminal and the second terminal 22 can be electrically connected.

[0023] The portable fan in the above embodiments has diverse usage scenarios. When the user separates the charging unit 200 and the air outlet 100, the user can use the air outlet 100 alone. For example, the user can hold the air outlet 100 while putting the charging unit 200 in a pocket or handbag, saving the user's hand strength. Alternatively, the user can clip the air outlet 100 to clothing or pants to blow air onto the waist or other areas, while putting the charging unit 200 in a pocket or handbag, completely freeing the user's hands, suitable for high-altitude work. When the user connects the charging unit 200 and the air outlet 100, the user can also use the entire unit, such as holding the entire unit or clipping it to clothing or pants to blow air onto the waist or other areas. Although this requires more effort, it allows for direct use while saving disassembly time. Furthermore, in this embodiment, the charging unit 200 and the air outlet 100 are connected by a surface-to-surface fit, saving space and creating an aesthetically pleasing design.

[0024] In some embodiments of this application, the outer peripheral surface of the housing 13 is circular, and the first surface 23 is a concave arc surface, with the curvature of the first surface 23 being the same as that of the outer peripheral surface of the housing 13. The housing 13 is a hollow cylinder, and the two end faces of the housing 13 are interconnected. The circular outer peripheral surface of the housing 13 and the concave arc surface of the first surface 23 allow the charging part 200 to fit snugly against the air outlet 100, and the fact that the curvature of the first surface 23 is the same as that of the outer peripheral surface of the housing 13 further allows the charging part 200 to fit snugly against the air outlet 100, achieving a space-saving and aesthetically pleasing effect. Simultaneously, the concave arc surface of the first surface 23 provides sufficient space to accommodate the second connecting component 21 and the second terminal 22, further achieving the space-saving effect. Furthermore, the concave arc surface design of the first surface 23, with its enveloping shape, protects the second terminal 22 and reduces weathering of the second terminal 22.

[0025] Furthermore, along the direction from the charging section 200 toward the air outlet 100, the projection of the first surface 23 onto the housing 13 does not extend beyond the housing 13. For example... Figure 4As shown, the direction of the charging unit 200 toward the air outlet 100 is indicated by the arrow, which is horizontal. Along the arrow, the projection of the first surface 23 onto the housing 13 does not extend beyond the housing 13. The portable fan housing 13 also includes a clip assembly 14, which is disposed on the housing 13 but not on the outer peripheral surface of the housing 13 corresponding to the first surface 23. The projection of the first surface 23 onto the housing 13 can fall onto the clip assembly 14, or the entire projection of the first surface 23 onto the housing 13 but not onto the clip assembly 14. In general, the projection of the first surface 23 onto the housing 13 does not extend beyond the housing 13. This design allows the first surface 23 to fit snugly against the outer peripheral surface of the housing 13. This snug fit design saves space and is aesthetically pleasing. At the same time, because the first surface 23 fits snugly against the outer peripheral surface, it can protect the first terminal 12 and the second terminal 22, reducing the weathering of the first terminal 12 and the second terminal 22.

[0026] The air outlet 100 may or may not be equipped with a clip assembly 14. When the clip assembly 14 is provided, it is used to clamp the air outlet 100 onto trousers or clothing, or other locations. However, if there is a space on the trousers or clothing, or other locations, to accommodate the air outlet 100, and the air outlet 100 can be secured without the clip assembly 14, then the clip assembly 14 may not be required.

[0027] In some embodiments of this application, the first connecting component 11 is disposed on the housing 13, and / or the first connecting component 11 is disposed inside the air outlet 100, while the second connecting component 21 is disposed on the first surface 23, and / or the second connecting component 21 is disposed inside the charging part 200.

[0028] The first connecting component 11 can be one or more. When there is only one, the first connecting component 11 is disposed on the housing 13 or inside the air outlet 100. When there are multiple components, some of the first connecting components 11 are disposed on the housing 13, and others are disposed inside the air outlet 100. The first connecting component 11 is disposed on the outer peripheral surface corresponding to the first surface 23, and / or inside the air outlet 100 corresponding to the first surface 23. Similarly, the second connecting component 21 can also be one or more. When there is only one, the second connecting component 21 is disposed on the first surface or inside the charging part 200. When there are multiple components, some of the second connecting components 21 are disposed on the first surface, and others are disposed inside the charging part 200. With this scheme, the placement of the first connecting component 11 and the second connecting component 21 can be diversified, making the connection between the air outlet 100 and the charging part 200 more secure and easier to disassemble.

[0029] Please see Figure 5 The first connecting component 11 includes a first magnetic member 111, which is disposed inside the air outlet 100 and is close to or in close contact with the outer peripheral surface. The second connecting component 21 includes a second magnetic member 211, which is disposed inside the charging section 200 and is close to or in close contact with the first surface 23. With this design, the first magnetic member 111 and the second magnetic member 211 can be detachably connected to the charging section 100 and the air outlet 200 through magnetic attraction. The fact that the first magnetic member 111 is close to or in close contact with the outer peripheral surface, while the second magnetic member 211 is close to or in close contact with the first surface 23, makes the magnetic attraction of the first magnetic member 111 and the second magnetic member 211 stronger.

[0030] See Figure 2 , Figure 3 and Figure 5 The first connecting component 11 further includes a first snap-fit ​​portion 112, and the second connecting component 21 further includes a second snap-fit ​​portion 212. The first snap-fit ​​portion 112 is disposed on the outer peripheral surface, and the second snap-fit ​​portion 212 is disposed on the first surface 23. When the first snap-fit ​​portion 112 and the second snap-fit ​​portion 212 approach each other, the first magnetic suction member 111 and the second magnetic suction member 211 move from being misaligned to being mated, so that the first snap-fit ​​portion 112 and the second snap-fit ​​portion 212 engage.

[0031] When the first latching portion 112 and the second latching portion 212 approach each other, under the magnetic attraction of the first magnetic member 111 and the second magnetic member 211, the first latching portion 112 and the second latching portion 212 achieve initial engagement, for example, the second latching portion 212 extends into the first latching portion 112. When the first magnetic member 111 and the second magnetic member 211 move from mutual misalignment to mutual docking, the first latching portion 112 and the second latching portion 212 achieve final engagement, for example, through a claw and a bayonet connection. It can be understood that the mutual misalignment of the first magnetic member 111 and the second magnetic member 211 specifically means that the projected portion of the first magnetic member 111 overlaps with that of the second magnetic member 211, while the mutual docking of the first magnetic member 111 and the second magnetic member 211 specifically means that the first magnetic member 111 and the second magnetic member 211 achieve magnetic attraction. When the first latching part 112 and the second latching part 212 are engaged, the first terminal 12 and the second terminal 22 are electrically connected to enable the charging part 200 to charge the air supply part 200.

[0032] The first latching part 112 is a latch, and the second latching part 212 is a claw. The latch is not limited to a through hole or other shape that penetrates the housing 13. The claw includes a plug-in end 214 and a connecting end 213. One end of the connecting end 213 is connected to the charging part 100, and the other end of the connecting end 213 is connected to the plug-in end 214. The cross-sectional area of ​​the plug-in end 214 is larger than the cross-sectional area of ​​the connecting end 213, and the cross-sectional area of ​​the plug-in end 214 is smaller than the cross-sectional area of ​​the latch. When the first magnetic suction member 111 and the second magnetic suction member 211 move from being misaligned to being aligned, the plug-in end 214 can extend into the latch and can latch onto the latch.

[0033] It should be noted that the latch is located on the air outlet 100, while the claw is located on the charging part 200. The latch design makes the outer peripheral surface of the air outlet 100 flat. When the air outlet 100 and the charging part 200 are separated, the appearance of the air outlet 100 will not appear abnormal due to the protrusion. The claw is located on the first surface 23 of the charging part 200. Since the first surface is concave, the claw is enclosed in the first surface 23, and the appearance of the charging part 200 also looks good.

[0034] In some embodiments of this application, the portable fan further includes a first mounting bracket 15 and a second mounting bracket 24. The first mounting bracket 15 is mounted on the outer peripheral surface, and the second mounting bracket 24 is mounted on the first surface 23. A first connecting component 11 and a first terminal 12 are disposed on the first mounting bracket 15, and a second connecting component 21 and a second terminal 22 are disposed on the second mounting bracket 24. A first mounting groove 131 is formed on the outer peripheral surface of the housing 13, and the first mounting bracket 15 is disposed at the first mounting groove 131. The curvature of the first mounting bracket 15 is the same as the curvature of the housing 13. A first mounting groove 231 is formed on the first surface 23, and the second mounting bracket 24 is disposed at the first mounting groove 231. The curvature of the second mounting bracket 24 is the same as the curvature of the first surface 23.

[0035] In some embodiments of this application, please refer to Figure 2 and Figure 3 The air outlet 100 also includes a first plug-in part 16, and the charging part 200 also includes a second plug-in part 26. When the air outlet 100 and the charging part 200 are disassembled and assembled, the air outlet 100 and the charging part 200 are connected to the first plug-in part 16 and the second plug-in part 26 through an external plug-in wire, so that the charging part 200 can charge the air outlet 100.

[0036] Please see Figure 6The air outlet 100 also includes a hollow structure bracket 17 and an end cap 10. The bracket 17 is disposed inside the housing 13 and is disposed adjacent to the housing 13. The distance between the bracket 17 and the housing 13 is 2mm-5mm. The end cap 10 is connected to the housing 13, for example, connected to the end side of the housing 13. The bracket 17 includes an end portion 173, which has a groove 1735. The groove 1735 is recessed inward from the end portion 173 near the end cap 10. The first plug-in portion 16 includes a first power terminal 161 and a first plug-in interface 162. The first power terminal 161 is disposed in the groove 1735, while the first plug-in interface 162 is disposed on the end cap 10. The first power terminal 161 and the first plug-in interface 162 are disposed opposite to each other. Specifically, the first power terminal 161 extends into the first plug-in interface 162, or the first power terminal 161 does not extend into the first plug-in interface 162, but the first power terminal 161 and the first plug-in interface 162 are disposed adjacent to each other.

[0037] Please see Figure 5 and Figure 6 An air inlet 18 is provided on the outer peripheral surface of the housing 13. The air inlet 18 is located on the side of the outer peripheral surface of the housing 13 near the end cover 10. There are multiple air inlets 18, which are arranged around the outer peripheral surface of the housing 13. An air outlet 19 is also provided on the side of the air outlet 100 away from the end cover 10. Air enters the interior of the housing from the air inlet 18 and is blown out from the air outlet 19.

[0038] The bracket 17 includes a first bracket 171 and a second bracket 172. The first bracket 171 houses a fan assembly 176, which includes a fan 1761, a motor 1762, and a pressurizing component 1763. The motor 1762 is connected to the fan 1761 to drive the fan 1761 to rotate, and the pressurizing component 1763 is used to pressurize the air generated by the fan 1761. The end 173 is disposed on the second bracket 172. The second bracket 172 also includes a plurality of adjacent ribs 1721, and the number of ribs 1721 can be up to 6. The adjacent ribs 1721 form an air inlet area, which is disposed opposite to the air inlet 18. The end 173 is provided with a mixing section 174, which protrudes into the housing 13 from the end face of the end 173, and the end face of the mixing section 174 near the end cover 10 is recessed to form a groove 1735.

[0039] Please see Figure 7Air flows in from the air inlet 18, passes through the air intake area, and enters the housing 13. Some of the air is blown towards the mixing section 174. At this time, this part of the air generates mixing on the outer periphery of the mixing section 174, which enhances the air force. At the same time, the air can also generate mixing in the air intake area formed between adjacent ribs 1721 (the mixing in the air intake area is not shown in the figure). The generation of two mixings can further enhance the air force. After mixing, the air passes through the fan assembly 176 and is blown out of the air outlet 19. However, some of the air does not blow out of the mixing section 174, but blows into the second bracket 172. After rotating in the second bracket 172, this part of the air passes through the fan assembly 176 and is blown out of the air outlet 19.

[0040] In some embodiments of this application, the mixing section 174 is a cylinder. The shape of the cylinder is designed to allow the wind to form a rotating airflow. The outer circumferential surface of the cylinder is a smooth outer circumferential surface to avoid other obstacles affecting the generation of mixing and further increase the wind force.

[0041] In some embodiments of this application, along the axial direction of the support 17, the length of the mixing portion 174 is less than the length of the rib 1721, and the axial direction of the support 17 is... Figure 7 The arrow points in the direction from the end cover 10 towards the air outlet 19. Air flows in from the air inlet 18, passes through the air intake area, and enters the housing 13. Part of the air is blown towards the mixing section 174, while another part is blown into the second bracket 172. This portion of air blowing into the second bracket 172 rotates within it before being blown out of the air outlet 19 via the fan assembly 176. The air blowing towards the mixing section 174 is mixed on its outer periphery before being blown out of the air outlet 19 via the fan assembly 176. This design first generates a relatively weak airflow within the second bracket 172 and outputs it quickly, then distributes the mixed airflow after it is generated in the mixing section 174, thus increasing the airflow force and allowing the user to quickly feel the air. The length of the mixing section 174 is 1 / 3 to 1 / 2 of the length of the rib 1721, ensuring both strong airflow and a quick airflow experience for the user.

[0042] In some embodiments of this application, please refer to Figure 6 and Figure 8The mixing section 174 has a hollow structure. This hollow structure is manifested in two ways: either the end face of the mixing section 174 near the end cap 10 is recessed to form a groove 1735, or the opposite two end faces of the mixing section 174 are closed structures, while the middle of the mixing section 174 is hollowed out. A first opening 1741 is provided on the side wall of the mixing section 174, penetrating the side wall of the mixing section 174. The first opening 1741 and the hollow structure of the mixing section 174 are interconnected. There can be one or more first openings 1741, and the shape of the first opening 1741 can be square or circular, etc. This design allows for heat dissipation of the first electrical terminal 161 within the groove 1735, and also allows air to enter the groove 1735 through the first opening 1741, generating mixed flow before being output through the first opening 1741, further increasing the airflow.

[0043] The bottom wall of the mixing section 174 is also provided with a second port 1742. The first port 1741 and the second port 1742 are connected to each other. Air enters the groove 1735 through the first port 1741, generates mixing, and then exits through the first port 1741 or through the second port 1742.

[0044] The hollow structure of the mixing section 174 contains a circuit board 1743 and a first power terminal 161 connected to the circuit board 1743. The first power terminal 161 is further away from the bracket 17 than the circuit board 1743. Both the circuit board 1743 and the first power terminal 161 are at a predetermined distance from the inner wall of the mixing section 174. The air enters the groove 1735 through the first opening 1741. The predetermined distance can help generate mixing and further increase the air force.

[0045] In some embodiments of this application, see further reference. Figure 6 and Figure 8 The end portion 173 includes an outer ring portion 1731. Along the radial direction of the end portion 173, a hollow area 1732 is formed between the outer ring portion 1731 and the mixing portion 174. The outer ring portion 1731 and the mixing portion 174 are connected by two reinforcing ribs 1733, which are arranged opposite each other. This design allows wind energy to generate mixing in the hollow area 1732, further increasing wind power. (See reference...) Figure 9 The width of the hollow area 1732 in the radial direction is D1, and the diameter of the outer ring 1731 in the radial direction is D2. The width D1 is 1 / 5 to 1 / 3 of the diameter D2.

[0046] In some embodiments of this application, the air outlet 100 is further provided with a first filter element 20, which is disposed on the end cover 10. Specifically, the first filter element 20 is disposed on the end face of the end cover 10 near the bracket 17. The first filter element 20 is provided with a plurality of small holes (not shown in the figure). The diameter of the small holes is smaller than the diameter of the air inlet 18. The end cover 10 and the housing 13 are designed to be detachable. When the end cover 10 is removed from the housing 13, the dust on the first filter element 20 can be cleaned. When the end cover 10 is fixed on the housing 13, the first filter element 20 is disposed opposite to the air inlet 18, and the first filter element 20 filters the air coming in from the air inlet 18. The first filter element 20 is fixed or detachably connected to the end cap 10. The first filter element 20 can be clamped onto the end cap 10 by interference fit. When a little force is applied, the first filter element 20 can be removed from the end cap 10. The first filter element 20 can be cleaned separately. When the first filter element 20 is fixed to the end cap 10, the first filter element 20 can be cleaned by holding the end cap 10.

[0047] In some embodiments of this application, the second support 172 includes a plurality of adjacent ribs 1721, and the adjacent ribs 1721 form an air inlet area. The first filter element 20 is disposed between the second support 172 and the housing 13. With this scheme, after the air enters the air outlet 100 from the air inlet 18, it is filtered by the first filter element 20 and then immediately enters the interior of the air outlet 100 through the air inlet area, reducing the damage of the air.

[0048] In some embodiments of this application, there are multiple air inlets 18, which surround the rear side of the outer peripheral surface of the housing 13. The first filter element 20 is a hollow cylinder with an arc that is approximately the same as the arc of the housing 13. The first filter element 20 surrounds the second bracket 172, and the arc of the first filter element 20 is also approximately the same as the arc of the second bracket 172. The distance between the first filter element 20 and the housing 13 is 2mm-5mm, while the distance between the first filter element 20 and the second bracket 172 is 3mm-6mm. The distance between the first filter element 20 and the second bracket 172 is always greater than the distance between the first filter element 20 and the housing 13.

[0049] In some embodiments of this application, the end cap 10 includes a first part 102 and a second part 103, which are disposed on the end face of the end cap 10 near the housing 13. The first part 102 and the second part 103 have a predetermined interval, and the first filter element 20 is snapped into the predetermined interval. The first filter element 20 can be snapped into the predetermined interval by a fixing method or by an interference fit. The predetermined interval is less than or equal to the thickness of the first filter element 20, so that the first filter element 20 can be removed from the end cap 10 with slight force.

[0050] In some embodiments of this application, the outer peripheral surface of the first part 102 is provided with a first engaging portion 1021, which is a protrusion extending outward from the outer peripheral surface of the first part 102. The housing 13 is provided with a second engaging portion 132, which is a groove on the housing 13. The first engaging portion 1021 and the second engaging portion 132 are engaged and connected to achieve the connection between the end cap 10 and the housing 13. It can be understood that the first engaging portion 1021 can also be an opening recessed inward from the outer peripheral surface of the first part 102, and the second engaging portion 132 can be a protrusion on the housing 13, which can also achieve the engagement and connection between the first engaging portion 1021 and the second engaging portion 132 to achieve the connection between the end cap 10 and the housing 13.

[0051] Furthermore, the first part 102 is a ring-shaped body. However, the first part 102 may not be a continuous ring-shaped body, or it may be a ring-shaped body with breaks. Setting the first part 102 as a ring-shaped body makes it easy to set the first snap-fit ​​part 1021 in the first part 102. The second part 103 is a protrusion. The curvature of the protrusion is the same as the curvature of the ring-shaped body, so that the first filter element 20 can be snapped between the first part 102 and the second part 103. At the same time, the protrusion has a small volume, which can save space and save costs.

[0052] In some embodiments of this application, please refer to Figure 6 and Figure 10 The end cap 10 is also provided with a second filter element 101. The second filter element 101 can be fixedly installed with the end cap 10 or detached. The second filter element 101 has several small holes (not shown in the figure). The diameter of the small holes on the second filter element 101 is approximately the same as the diameter of the small holes on the first filter element 20. The second filter element 101 can allow air to enter through the end cap 10 and can also filter the air. The second filter element 101 is arranged perpendicularly to the first filter element 20. The first filter element 20 can both filter the air from the air inlet 18 and reduce obstruction of the air entering through the second filter element 101.

[0053] The air inlet 18 allows air to enter from the rear side of the housing 13, and the second filter 101 allows air to enter from the rear end face of the housing 13. The mixing section 174 is arranged opposite to the air inlet 18. The air blows from the air inlet 18 to the side wall of the mixing section 174, and the air passing through the second filter 101 is parallel to the side wall of the mixing section 174, further increasing the mixing effect.

[0054] In some embodiments of this application, the end cap 10 and the end 173 of the bracket 17 are detachably connected. A first connecting portion 1791 is provided on the reinforcing rib 1733, and the first connecting portion 1791 can be a first threaded hole. A second connecting portion 104 is provided on the end cap 10, and a reinforcing rib 105 is also provided on the end cap 10. The second connecting portion 104 is provided on the reinforcing rib 105, and the second connecting portion 104 can be a second threaded hole. The first connecting portion 1791 and the second connecting portion 104 are connected by a connector 106, which can be a screw. The screw passes through the first threaded hole and the second threaded hole respectively to fix the end cap 10 to the end 173. The connector 106 can also be detached from the first connecting portion 1791 and the second connecting portion 104 to allow the end cap 10 and the end 173 to be disassembled.

[0055] In some embodiments of this application, at least one electronic control element is provided on the housing 13, such as a first terminal 12 and a switch button 133. The switch button 133 is used to turn the air outlet 100 on and off. The bracket 17 is provided with at least one first receiving portion 175, which is disposed opposite to the electronic control element. When the electronic control element has a switch button 133, the bracket 17 is provided with a first receiving portion 175 disposed opposite to the switch button 133. When the electronic control element has a first terminal 12, the bracket 17 is provided with a first receiving portion 175 disposed opposite to the first terminal 12. Alternatively, when there are other electronic control elements, the bracket 17 is provided with other first receiving portions 175 disposed opposite to other electronic control elements. The shape of the first receiving portion 175 can be square or other shapes, which can be set according to the shape of the electronic control element. The first receiving portion 175 can be an opening or a groove. The first receiving portion 175 accommodates a wire (not shown in the figure), which is electrically connected to the electronic control element. This solution adopts a high-density integrated wiring design, rationally plans the circuit routing path, effectively reduces the internal space occupation, and makes the overall structure of the air outlet more compact and lightweight.

[0056] Please refer to Figure 8 and Figure 11The bracket 17 is provided with a second receiving portion 177, which can be square or other shapes. The second receiving portion 177 can be an opening or a recess. The second receiving portion 177 accommodates wiring (not shown) or a control board 1771. The wiring board 1743 is electrically connected to the control board 1771. The wiring of the first receiving portion 175 is also electrically connected to the control board 1771. The control board 1771 is provided with processing sensors and other signal modules. The control board 1771 is used to coordinate the operation of the fan assembly 176, the switch button 133, and the first terminal 12, etc. The control board 1771 can be accommodated in the second receiving portion 177, or it can be accommodated between the bracket 17 and the housing 13. Alternatively, part of the control board 1771 can be accommodated in the second receiving portion 177, and another part can be accommodated between the bracket 17 and the housing 13.

[0057] The bracket 17 is also provided with a wire channel 178. The wire channel 178 is rectangular or other shapes. The wire channel 178 connects the first receiving part 175 and the second receiving part 177. The wires on the first receiving part 175 are connected to the control board 1771 through the wire channel 178. The wire channel 178 is a groove or opening on the bracket 17. It is better to set the wire channel 178 as a groove because the wires will not enter the bracket through the groove.

[0058] The clip assembly 14 on the air outlet 100 includes a clip 141 and a support base 142. The clip 141 is connected to the upper surface of the support base 142. The end of the support base 142 facing the housing 13 has a first opening (not shown in the figure), and the part of the housing 13 corresponding to the support base 142 has a second opening (not shown in the figure). The first opening and the second opening are mated together so that the support base 142 is connected to the housing 13. The size of the first opening is smaller than that of the second opening, so that the first opening can engage with the second opening. The support base 142 accommodates a wiring or control board 1771. The control board 1771 can be fully accommodated on the support base 142, or partially accommodated on the support base 142, with the other part accommodated on the second accommodating part 177. The wiring can be fully accommodated on the support base 142, or partially accommodated on the support base 142, with the other part accommodated on the second accommodating part 177.

[0059] The first bracket 171 houses the fan assembly 176, and the outer peripheral surface of the housing 13 corresponding to the second bracket 172 is provided with an air inlet 18. The adjacent ribs 1721 on the second bracket 172 constitute the air inlet area. The first receiving part is provided on the first bracket, and the first receiving part 175 is provided on the first bracket 171.

[0060] The outer surface of the second bracket 172 is connected to the inner surface of the first bracket 171, that is, the outer surface of the end of the second bracket 172 near the first bracket 171 is connected to the inner surface of the end of the first bracket 171 near the second bracket 172. The first receiving part 175 passes through the end of the first bracket 171 near the second bracket 172. That is, the first receiving part 175 has an opening 1751. When air enters through the air inlet 18, part of the air enters the circuit through the end of the first bracket 171, that is, part of the air enters the circuit through the opening 1751. The circuit acts as sound-absorbing cotton to absorb the air entering through the opening 1751, thereby achieving the effect of sound absorption.

[0061] Along the radial direction of the air outlet 100, the first mounting groove 131 and the first receiving portion 175 at least partially overlap. The projection of the first mounting groove 131 onto the first receiving portion 175 can completely fall onto the first receiving portion 175. This allows the first receiving portion 175 to have an opening 1751, and the first mounting groove 131 does not correspond to the second bracket 172, thus not affecting air intake. The projection of the first mounting groove 131 onto the first receiving portion 175 can partially fall onto the first receiving portion 175, with at least half of the projection of the first mounting groove 131 falling onto the first receiving portion 175.

[0062] The housing 13 is provided with an air inlet 18 corresponding to the second bracket 172. The first filter element 20 is disposed between the second bracket 172 and the housing 13. The first filter element 20 is used to filter the air coming in through the air inlet 18. The filtered air passes through the first filter element 20 and then through the ribs 1721 on the second bracket 172 before entering the interior of the bracket 17. The first mounting bracket 15 on the housing is provided with an electronic control element. A circuit is provided between the first mounting bracket 15 and the bracket 17. The first mounting bracket 15 has an end 151 adjacent to the first filter element 20. There is a predetermined distance between the end 151 and the first filter element 20. The predetermined distance is approximately 1mm-3mm. The air can enter the circuit through the predetermined distance. The circuit acts as a sound-absorbing cotton to absorb the sound of the air and achieve the effect of sound absorption.

[0063] The fan assembly 176 includes a cylinder 1764 and a silencer 1765. The cylinder 1764 has openings at both ends and a hollowed-out middle section, with the openings at both ends communicating with each other. The silencer 1765 is mounted on the outer surface of the cylinder 1764. The silencer 1765 also has openings at both ends and a hollowed-out middle section, with the openings at both ends communicating with each other. The diameter of the silencer 1765 is larger than the diameter of the cylinder 1764, and the silencer 1765 is fitted onto the outer surface of the cylinder 1764. The first receiving portion 175 is open, meaning it passes through the bracket 17. The wiring is arranged between the silencer 1765 and the first mounting bracket 15, meaning the wiring passes through the first receiving portion 175. This design allows the wiring to be positioned on the outer periphery of the silencer 1765, while the wiring acts as sound-absorbing material, resulting in a two-layer sound-absorbing structure that effectively reduces noise.

[0064] Similarly, the second receiving portion 177 is also an opening, meaning that the second receiving portion 177 passes through the bracket 17, and the wiring is arranged between the silencing component 1765 and the support base 142, that is, the wiring passes through the second receiving portion 17. With this design, the wiring is located on the outer periphery of the silencing component 1765, and the wiring acts as the sound-absorbing cotton, resulting in better sound absorption from the two-layer sound-absorbing structure.
