[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 3 The air duct structure 100 according to the embodiment of the present invention is described, comprising: a housing 10, a mounting bracket 20, an air duct body 30 and a partition. The housing 10 has a first direction A and a second direction B.

[0029] Specifically, if Figure 1-Figure 3 As shown, the mounting bracket 20 is connected to the shell 10, and the mounting bracket 20 and the shell 10 define an air outlet 21; the air duct main body 30 is arranged between the shell 10 and the mounting bracket 20, and the air duct main body 30 is formed with an air duct outlet 31, and the air duct outlet 31 is connected to the air outlet 21; the partition is arranged between the mounting bracket 20 and the shell 10 to limit the air outlet direction of the air outlet 21.

[0030] Combination Figure 1 and Figure 2The mounting bracket 20 is disposed in the housing 10 along the first direction A of the housing 10, the air duct body 30 is disposed between the housing 10 and the mounting bracket 20 along the first direction A of the housing 10, the air duct body 30 is formed with an air duct extending along the second direction B of the housing 10, and the upper end of the air duct along the second direction B is formed with an air duct outlet 31 suitable for communicating with the air outlet 21. The mounting bracket 20 and the housing 10 also define an air inlet 24, and the outside air enters the housing 10 through the air inlet 24 and then flows into the air duct, and then flows through the air duct outlet 31 and flows out of the housing 10 through the air outlet 21, so that the air circulates in the housing 10.

[0031] According to the air duct structure 100 of the embodiment of the utility model, the air duct structure 100 is applied to the beauty instrument, and the mounting bracket 20 and the housing 10 define an air outlet 21 to facilitate the circulation of air in the housing 10. The air circulates in the air duct body 30 and flows out through the air outlet 21 to achieve the heat dissipation effect on the internal components of the beauty instrument. The setting of the partition can separate the air inlet side and the air outlet side between the mounting structure and the housing 10, prevent the air with a lower temperature from interfering with the air with a higher temperature after heat exchange, and improve the heat exchange efficiency of the heat exchange airflow in the air duct structure 100.

[0032] According to some embodiments of the present invention, Figure 2 As shown, the housing 10 and the mounting bracket 20 define an air inlet 24 and an air outlet 21 , and a partition is provided between the air inlet side of the air inlet 24 and the air outlet side of the air outlet 21 .

[0033] A certain space is defined between the housing 10 and the mounting bracket 20. A partition is provided between the mounting bracket 20 and the housing 10 to divide the space between the mounting bracket 20 and the housing 10 into two spaces spaced apart along the second direction B of the housing 10, wherein the space located below the partition along the second direction B of the housing 10 is the air inlet side, and the space located above the partition along the second direction B of the housing 10 is the air outlet side. The air inlet 24 is connected to the air duct, and the outside air enters the housing 10 through the air inlet 24 and flows through the air inlet side and then into the air duct, and then flows through the air duct outlet 31 and flows out of the housing 10 through the air outlet 21, thereby realizing the circulation of air in the housing 10.

[0034] Therefore, the setting of the partition can separate the space between the mounting bracket 20 and the shell 10 into an air outlet side for air outlet and an air inlet side for air inlet, so that the air inlet path and the air outflow path in the shell 10 do not interfere with each other, and the air flow path can be limited, thereby improving the working efficiency of the air duct structure 100.

[0035] According to some embodiments of the present invention, Figure 2As shown, the air outlet 21 includes: a first outlet 22 and a second outlet 23. The first outlet 22 is formed on the mounting bracket 20 and is opposite to the air duct outlet 31. The shell 10 and the mounting bracket 20 define the second outlet 23, and the second outlet 23 extends along the circumference of the shell 10.

[0036] The first outlet 22 is arranged through the mounting bracket 20 along the first direction A of the housing 10. The first outlet 22 is opposite to the air duct outlet 31 on one side along the first direction A of the housing 10, and is opposite to the housing 10 on the other side along the first direction A of the housing 10. A second outlet 23 is defined between the outer peripheral edge of the housing 10 and the outer peripheral edge of the mounting bracket 20. The second outlet 23 extends along the circumference of the housing 10 and the mounting bracket 20, and the second outlet 23 is arranged at the upper half of the housing 10 along the second direction B. The second outlet 23 is connected to the first outlet 22 through the air outlet side, and the air flowing out of the air duct outlet 31 passes through the first outlet 22, the air outlet side and the second outlet 23 in sequence, and flows to the outside from the second outlet 23.

[0037] Therefore, the setting of the first outlet 22 and the second outlet 23 presets a flow path for the air, which is convenient for the circulation of air in the air duct structure 100. The second outlet 23 extends along the circumference of the shell 10 to form a hidden air outlet 21, which can optimize the spatial layout inside the air duct structure 100, improve the space utilization rate inside the air duct structure 100, reduce the space occupied by the second outlet 23 on the shell 10, and make the appearance of the air duct structure 100 more neat and beautiful.

[0038] According to some embodiments of the present invention, Figure 2 As shown, the shell 10 includes: a first shell 11 and a second shell 12, the air duct main body 30 is arranged in the first shell 11, the mounting bracket 20 is arranged on the side of the air duct main body 30 away from the first shell 11, and the mounting bracket 20 is connected to the first shell 11; the second shell 12 is arranged on the side of the mounting bracket 20 away from the first shell 11, and a partition is arranged between the second shell 12 and the mounting bracket 20; the air duct main body 30 is formed with an air duct inlet 32, and the mounting bracket 20 and the second shell 12 define an air inlet 24, and the air inlet 24 is opposite to the air duct inlet 32.

[0039] The air duct body 30 and the mounting bracket 20 are arranged between the first shell 11 and the second shell 12. Along the first direction A of the shell 10, the air duct body 30 is arranged between the first shell 11 and the mounting bracket 20, the mounting bracket 20 is arranged between the air duct body 30 and the second shell 12, and the partition is arranged between the mounting bracket 20 and the second shell 12. The air duct defined by the air duct body 30 is formed with an air duct inlet 32 ​​at the lower end along the second direction B of the shell 10. The air inlet 24 includes: a first inlet 25 and a second inlet 26. The first inlet 25 is arranged through the mounting bracket 20 along the first direction A of the shell 10, and the first inlet 25 is opposite to the air duct inlet 32. The shell 10 and the mounting bracket 20 define the second inlet 26, which extends along the circumference of the shell 10, and the second inlet 26 is defined between the outer peripheral edge of the shell 10 and the outer peripheral edge of the mounting bracket 20, and the second inlet 26 is arranged at the lower half of the shell 10 along the second direction B. The first inlet 25 and the second inlet 26 are connected through the air inlet side, and the outside air flows into the shell 10 from the second inlet 26, passes through the air inlet side, the first inlet 25 and the air duct inlet 32 ​​in sequence, and then passes through the air duct outlet 31, the first outlet 22, the air outlet side and the second outlet 23, and flows to the outside from the second outlet 23.

[0040] Other components of the beauty instrument are arranged between the air duct body 30 and the first housing 11. When the beauty instrument is working, these components will emit a certain amount of heat, causing the temperature of the beauty instrument to rise. A fan 33 is arranged at the air duct inlet 32. When the fan 33 rotates, the outside air can enter the housing 10 through the second inlet 26 of the housing 10, and the outside air can circulate in the air duct structure 100, so as to achieve the heat dissipation effect on other components inside the beauty instrument.

[0041] Therefore, the setting of the first inlet 25 and the second inlet 26 presets a flow path for the air. The first inlet 25 and the air duct inlet 32 ​​are relatively convenient for the air entering the shell 10 to flow directly into the air duct main body 30. The first inlet 25 extends along the circumference of the shell 10 to form a hidden air inlet 24, which can optimize the spatial layout inside the air duct structure 100, reduce the space occupied by the first outlet 22 on the shell 10, and make the appearance of the air duct structure 100 more neat and beautiful.

[0042] According to some embodiments of the present invention, Figure 3As shown, the air guide assembly 40 is also included: the air guide assembly 40 is arranged at the air outlet 21; the air guide assembly 40 includes: a guide rib, the guide rib is arranged on the side surface of the mounting bracket 20 away from the air duct body 30; the guide rib is formed by a part of the side surface of the mounting bracket 20 away from the air duct body 30 protruding along the first direction A of the shell 10 toward the side of the second shell 12. Alternatively, the guide rib is arranged on the side surface of the shell 10 facing the air outlet 21; the guide is formed by a part of the side surface of the second shell 12 adjacent to the mounting bracket 20 protruding along the first direction A of the shell 10 toward the side close to the mounting bracket 20. Alternatively, the guide rib is arranged on both the side surface of the mounting bracket 20 away from the air duct body 30 and the side surface of the shell 10 facing the air outlet 21. Wherein, the guide rib extends toward the edge of the mounting bracket 20.

[0043] Therefore, the guide ribs are provided to limit the air outlet direction. The guide ribs are provided on the air outlet side, and extend toward the edge of the mounting bracket 20, that is, toward the second outlet 23. The air flowing out of the first outlet 22 can pass through the guide ribs on the air outlet side and then flow to the outside of the air duct structure 100 through the second outlet 23, thereby guiding the flow direction of the air and making the air circulation efficiency inside the air duct structure 100 higher.

[0044] According to some embodiments of the present invention, Figure 3 As shown, the air guide assembly 40 is rotatably connected to the mounting bracket 20, and the air guide assembly 40 is disposed on a side of the mounting bracket 20 away from the air duct body 30 along the first direction A of the housing 10, and the air guide assembly 40 is rotatable relative to the mounting bracket 20. Alternatively, the air guide assembly 40 is rotatably connected to the housing 10. The air guide assembly 40 is disposed on a side of the second housing 12 adjacent to the mounting bracket 20 along the first direction A of the housing 10, and the air guide assembly 40 is rotatable relative to the housing 10. The air guide assembly 40 is between the second housing 12 and the mounting bracket 20, and the air guide assembly 40 is suitable for being opposite to the first outlet 22.

[0045] Thus, the air flowing out from the first outlet 22 flows through the air guide assembly 40, and the air guide assembly 40 is connected to the mounting bracket 20 or the shell 10 to change the flow direction of the air blown out from the second outlet 23. The air guide assembly 40 rotates clockwise and counterclockwise within a certain angle range, thereby changing the flow direction of the air blown out from the first outlet 22 after passing through the air guide assembly 40.

[0046] According to some embodiments of the present invention, Figure 3 As shown, the air guide assembly 40 includes: a fixed member 41 and a plurality of swing members 42, the fixed member 41 is connected to the mounting bracket 20 or the housing 10; the plurality of swing members 42 are arranged at intervals along the length direction of the fixed member 41, and the plurality of swing members 42 are rotatably connected to the fixed member 41.

[0047] The two ends of the fixed member 41 along the length direction are fixedly connected to the mounting bracket 20 or the housing 10, and a plurality of swinging members 42 are arranged at intervals along the length direction of the fixed member 41. The swinging members 42 are rotatable relative to the fixed member 41, and the swinging members 42 can rotate counterclockwise or clockwise at a certain angle relative to the fixed member 41. The same end of the plurality of swinging members 42 is rotatably connected to a connecting member 43. When the plurality of swinging members 42 rotate, the connecting member 43 can also be driven to generate a certain displacement relative to the fixed member 41, and the connecting member 43 can rotate counterclockwise or clockwise at a certain angle relative to the plurality of swinging members 42. The arrangement of the connecting member 43 can ensure that the rotation angles of the plurality of swinging members 42 relative to the fixed member 41 are the same, and ensure the synchronization of the rotation of the plurality of swinging members 42.

[0048] Therefore, the fixing member 41 is connected to the mounting bracket 20 or the shell 10 to facilitate the fixed installation of the swinging member 42. The multiple swinging members 42 are arranged at intervals. The air blown out from the first outlet 22 flows through the air guide assembly 40 from the multiple intervals defined by the multiple swinging members 42. The multiple swinging members 42 are rotatably connected to the fixing member 41. By adjusting the rotation angle of the multiple swinging members 42, the air flow direction can be changed to enhance the user experience.

[0049] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cross-sectional area of ​​the second outlet 23 gradually increases in a direction away from the center of the housing 10 .

[0050] The surface of the second shell 12 opposite to the second outlet 23 extends obliquely in a direction away from the center of the shell 10, and the surface of the second shell 12 extends obliquely in a direction away from the center of the shell 10, and the surface of the second shell 12 extends obliquely in a direction away from the center of the shell 10, and the surface of the mounting bracket 20 extends obliquely in a direction away from the center of the shell 10, and the surface of the mounting bracket 20 extends obliquely in a direction away from the center of the shell 10, and the surface of the mounting bracket 20 extends obliquely in a direction away from the center of the shell 10, and the surfaces of the second shell 12 and the mounting bracket 20 extend obliquely in a direction away from each other. That is, along the direction away from the center of the shell 10, the distance between the edge of the second shell 12 and the edge of the first mounting bracket 20 gradually increases.

[0051] Thus, the second outlet 23 is defined at the edge of the second shell 12 and the edge of the mounting bracket 20, and the cross-sectional area of ​​the second outlet 23 gradually increases in the direction away from the center of the shell 10, which can increase the speed of air flowing out of the air duct structure 100 from the second outlet 23, thereby improving the circulation efficiency of air inside the air duct structure 100. Similarly, the second inlet 26 is also defined at the edge of the second shell 12 and the edge of the mounting bracket 20, and the cross-sectional area of ​​the second inlet 26 gradually increases in the direction away from the center of the shell 10, thereby improving the air intake speed of air entering the air duct structure 100 from the second inlet 26, thereby improving the circulation efficiency of air inside the air duct structure 100.

[0052] According to some embodiments of the present invention, Figure 1 As shown, the housing 10 includes: a handheld portion, and an air outlet 21 is arranged at one end of the housing 10 away from the handheld portion. The handheld portion is arranged at the lower half of the housing 10 along the second direction B, the air outlet 21 is arranged at the upper end of the housing 10 along the second direction B, and the air inlet is arranged at the lower end of the housing 10 along the second direction B. Therefore, the air duct assembly is applied to the beauty instrument, the handheld portion is convenient for the user to hold the beauty instrument, and the air outlet 21 is arranged at one end of the housing 10 away from the handheld portion, which can prevent the user's hand from blocking the air outlet 21 when using the beauty instrument, so as to ensure the air outlet efficiency of the air duct assembly, and also prevent the hot air from being discharged to the user's hand, so as to improve the user's experience and the safety of the air duct assembly.

[0053] The beauty instrument according to the second embodiment of the utility model includes the air duct structure 100 according to the first embodiment of the utility model.

[0054] According to the beauty instrument of the embodiment of the utility model, by using the air duct structure 100 described in the above embodiment, the air duct structure 100 can extract the heat generated by the beauty instrument when it is working, and inhale the outside air through the air inlet 24. The airflow flows in the air duct structure 100, and the heat exchange of the beauty instrument can be completed. The setting of the air duct structure 100 can increase the flow speed of the heat exchange air in the air duct assembly, increase the flow rate of the air in the air duct structure 100, and then improve the heat dissipation effect of the air duct structure 100 on the beauty instrument, enhance the working efficiency of the beauty instrument, and improve the user's experience comfort when using the beauty instrument.
