[0023] Please see Figures 1 to 2 This invention provides an easy-to-install duct fan, comprising: The fan body 10 has at least one air outlet 11. At least one air duct 20 is provided at the end of the air duct 20, the adapter ring 21 is threaded with the air duct 20, the adapter ring 21 is detachably connected to the fan body 10, and the air duct 20 is connected to the air outlet 11.
[0024] The duct 20 is assembled with the fan body 10 through the adapter ring 21, avoiding the problem of difficult assembly due to the flexibility of the duct 20 itself. The adapter ring 21 can be made of rigid materials such as metal and plastic, and rigid materials can be assembled with the fan body 10 in more convenient ways.
[0025] Please see Figure 3 The specific structure of the duct 20 can be designed according to actual needs. For example, in some optional embodiments, the duct 20 includes a flexible tube body 22 and an elastic threaded support frame 23. The flexible tube body 22 forms a ventilation channel, and the threaded support frame 23 is disposed inside the flexible tube body 22 and extends threadedly around the ventilation channel. The flexible tube body 22 achieves threaded engagement with the adapter ring 21 through the threaded support frame 23. The threaded support frame 23 can support the flexible tube body 22 and also achieve threaded engagement between the duct 20 and the adapter ring 21.
[0026] Please see Figure 4 The detachable assembly method of the adapter ring 21 and the fan body 10 can be designed according to actual needs. For example, in some optional embodiments, at least one second elastic sealing ring 12 is provided on the fan body 10. The second elastic sealing ring 12 is arranged around the air outlet 11, and part of the fan body 10 passes through the adapter ring 21. The second elastic sealing ring 12 is located between the inner sides of the fan body 10 and the adapter ring 21. After the adapter ring 21 is fitted onto the outer side of the fan body 10, the second elastic sealing ring 12 achieves an interference fit with the fan body 10. The friction between the second elastic sealing ring 12 and the adapter ring 21 is used to prevent the adapter ring 21 from detaching from the fan body 10. In addition, the second elastic sealing ring 12 can also seal the gap between the adapter ring 21 and the fan body 10, thereby improving the sealing performance between the adapter ring 21 and the fan body 10. Of course, the adapter ring 21 can also be directly snapped into the fan body 10 without the need for the design of the elastic sealing ring, or the adapter ring 21 can be threaded into the fan body 10, or the adapter ring 21 can be snapped into the fan body 10 through a snap-fit structure.
[0027] In some alternative embodiments, at least one positioning ring groove 13 is provided on the outer side of the fan body 10, and the second elastic sealing ring 12 is positioned and engaged with the positioning ring groove 13. The positioning ring groove 13 can position the second elastic sealing ring 12, thereby preventing the second elastic sealing ring 12 from shifting its position.
[0028] The main body 10 of the fan typically has multiple air vents 11, which are air inlets 111 and at least one air outlet 112. There may be only one duct 20, which connects to either the air inlet 111 or one of the air outlets 112. The other air inlets 111 or air outlets 112 can be connected via other suitable pipes, without limiting each air vent 11 to a duct 20. In this embodiment, the easy-to-install duct fan includes multiple ducts 20, which are air inlets 24 and at least one air outlet 25. The air inlet 24 connects to the air inlet 111, and the air outlet 25 connects to the corresponding air outlet 112.
[0029] In some optional embodiments, a wind cavity 14 is formed inside the fan body 10, and the air outlet 112 and the air inlet 111 are both connected to the wind cavity 14. A fan outlet seat 15 is detachably provided on the fan body 10, and at least one second connecting part 151 is formed on the fan outlet seat 15. The air outlet 112 is correspondingly provided on the second connecting part 151. The second connecting part 151 is detachably inserted into the adapter ring 21 of the air outlet pipe 25. In this embodiment, a positioning ring groove 13 is provided on the outer side of the second connecting part 151, and a second elastic sealing ring 12 is arranged around the second connecting part 151.
[0030] Please see Figure 5 In some optional embodiments, the fan body 10 is provided with an installation port 16, and a plurality of first fasteners 161 are provided inside the installation port 16, which are evenly arranged around the installation port 16. The fan outlet seat 15 is provided with an installation part 152, and a plurality of second fasteners 153 are provided on the outer side of the installation part 152. The installation part 152 is assembled with the installation port 16, and the second fasteners 153 are engaged with the first fasteners 161. The air outlet 112 is connected to the air cavity 14 through the installation port 16. In this embodiment, when the installation part 152 extends into the installation port 16, the second fasteners 153 pass between adjacent first fasteners 161. Then the fan outlet seat 15 rotates, causing the second fasteners 153 to be rotated to the side of the first fasteners 161 away from the fan outlet seat 15, thereby restricting the second fasteners 153 from moving out of the installation port 16 by the first fasteners 161. In addition, to improve the positional stability of the first latching member 161 and the second latching member 153, the first latching member 161 is provided with a limiting protrusion 162, and the second latching member 153 is provided with an elastic buckle 154. The elastic buckle 154 engages with the limiting protrusion 162 to restrict the rotation of the mounting part 152 relative to the mounting opening 16. Of course, in this embodiment, the fan outlet seat 15 can also be detachably locked to the fan body 10 by multiple screws.
[0031] Please see Figure 6In some optional embodiments, a fan inlet seat 17 is detachably provided on the fan body 10. At least one third connection 171 is formed on the fan inlet seat 17, and an air inlet 111 is correspondingly disposed on the third connection 171. The third connection 171 is detachably inserted into the adapter ring 21 of the air inlet pipe 24. In this embodiment, a positioning ring groove 13 is provided on the outer side of the third connection 171, and a second elastic sealing ring 12 is arranged around the third connection 171. In this embodiment, the fan inlet seat 17 is detachably locked to the fan body 10 by multiple screws. Of course, the fan inlet seat 17 can also be detachably connected to the fan body 10 using the same installation method as the fan outlet seat 15.
[0032] Please see Figure 7 To facilitate the connection between the air outlet duct 25 and the indoor environment, in some optional embodiments, the easy-to-install duct fan also includes an indoor air inlet seat 30 for assembly with the indoor installation port 16, and the indoor air inlet seat 30 is provided with an air inlet channel 31; both ends of the air outlet duct 25 are respectively provided with adapter rings 21, and both ends of the air outlet duct 25 are detachably connected to the fan body 10 and the indoor air inlet seat 30 through the adapter rings 21, and the air outlet 112 is connected to the air inlet channel 31 through the air outlet duct 25. In this embodiment, the air cavity 14 is provided with a fan wheel 141 connected to the motor. The fan wheel 141 drives the airflow to pass sequentially through the air inlet duct 24, the air inlet 111, the air cavity 14, the air outlet 112, the air outlet duct 25, and the air inlet channel 31, and then the airflow enters the room.
[0033] In some optional embodiments, the indoor air inlet seat 30 is provided with a first connecting portion 32, which is correspondingly inserted into the adapter ring 21 at the end of the air outlet duct 25. A plurality of first elastic sealing rings 33 are sleeved on the outer side of the first connecting portion 32, located between the first connecting portion 32 and the inner side of the adapter ring 21 at the end of the air outlet duct 25. After the adapter ring 21 is sleeved on the outer side of the first connecting portion 32, an interference fit is achieved between it and the first connecting portion 32 through the first elastic sealing rings 33. The friction between the first elastic sealing rings 33 and the adapter ring 21 prevents the adapter ring 21 from detaching from the first connecting portion 32. Furthermore, the first elastic sealing rings 33 can also seal the gap between the adapter ring 21 and the first connecting portion 32, thereby improving the sealing performance between the adapter ring 21 and the first connecting portion 32. Of course, the adapter ring 21 can also be directly snapped into the indoor air inlet seat 30 without the need for the design of the elastic sealing ring, or the adapter ring 21 can be threaded into the indoor air inlet seat 30, or the adapter ring 21 can be snapped into the indoor air inlet seat 30 through a snap-fit structure.
[0034] In this embodiment, a positioning groove 33 for positioning the first elastic sealing ring 33 is provided on the outer side of the first connecting part 32, thereby preventing the first elastic sealing ring 33 from shifting its position.
[0035] In this embodiment, a protective net 34 is provided in the air inlet channel 31 to prevent mosquitoes from passing through.
[0036] Both the fan outlet seat 15 and the fan inlet seat 17 are detachable, facilitating the packaging and transportation of the fan body 10. In this embodiment, the fan body 10, the fan outlet seat 15, the fan inlet seat 17, the air duct 20, the adapter ring 21, and the indoor air inlet seat 30 are all detachable from each other, facilitating packaging and transportation.
[0037] Please see Figure 8 The indoor air inlet seat 30 is installed at the mounting hole in the indoor wall. For ease of installation, multiple spring clips 36 are provided on the side of the indoor air inlet seat 30. After the indoor air inlet seat 30 passes through the mounting hole in the indoor wall, the end of the indoor air inlet seat 30 is engaged with the indoor wall, while the spring clips 36 abut against the side of the wall away from the indoor wall, thereby fixing the indoor air inlet seat 30. The way the spring clips 36 fix the indoor air inlet seat 30 is similar to the way downlights on the market are fixed to the hole by spring clips. The principle and structure are well known to those skilled in the art and will not be described in detail here.
[0038] The length of the duct can be designed according to actual needs, and is not limited to what is shown in the illustration.
