DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the implementation scheme of the present invention, the technical solutions in the implementation scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the implementation scheme of the present invention. Obviously, the described implementation scheme is only a part of the implementation scheme of the present invention, not all of the implementation schemes. Based on the implementation scheme in the implementation scheme of the present invention, all other implementation schemes obtained by those skilled in the art without making creative work are within the scope of protection of the implementation scheme of the present invention.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Please also refer to Figures 1 to 3 The embodiment of the present invention provides an air outlet device 100, which can be a neck hanging fan. When worn, it can be roughly "U" shaped so that the user can wear it around the neck. In other embodiments, the air outlet device 100 can also be other.

[0033] The present invention provides an air outlet device 100, which includes a bracket 11 and an air outlet member 12. The bracket 11 is provided with an air inlet 111 and an air outlet 112. The air outlet member 12 is assembled to the bracket 11 and includes a housing 121, a power member 124, and axial flow blades 122. The power member 124 and the axial flow blades 122 are both assembled to the housing 121. The drive shaft of the power member 124 is connected to the axial flow blades 122, so that the power member 124 can provide the driving force required for the operation of the axial flow blades 122, helping to ensure the rotation of the axial flow blades 122.

[0034] In some embodiments, the housing 121 is provided with an air inlet 1211, an air outlet 1214, and a sound absorption hole 1212. The air inlet 1211 and the air outlet 1214 are opposite to each other and are located at opposite ends of the housing 121. The sound absorption hole 1212 is located on the peripheral side 1213 of the housing 121 and is located between the air inlet 1211 and the air outlet 1214. The air inlet 111 is provided at the end of the bracket 121 and is opposite to the air inlet 1211. The axial flow blades 122 are adapted to guide the generated airflow from the air inlet 1211 to the air outlet 1214 and blow it out through the air outlet 112. The air outlet member 12 can be assembled at the end of the bracket 11 and is opposite to the air inlet 111 at the end of the bracket 11.

[0035] In this way, the airflow in the shell 121 can be discharged to the outside of the shell 121 through the sound-absorbing holes 1212, which helps to reduce the flow resistance of the airflow in the shell 121, helps to balance the air pressure inside and outside the shell 121, helps to reduce the noise generated by the excessive air pressure of the airflow in the shell 121 when the axial flow fan blades 122 are working, helps to reduce the noise generated by the air outlet device 100, and also helps the sound-absorbing holes 1212 to disperse the noise in the shell 121, helps to reduce the decibels of noise, and helps to improve the user experience.

[0036] For example, wind can enter the bracket 11 from the air inlet 111 and enter the shell 121 through the air inlet 1211. Under the action of the axial flow fan blades 122, the wind in the shell 121 is blown out through the air supply port 1214 and finally discharged through the air outlet 112, thereby realizing the air outlet of the air outlet device 100.

[0037] The number of air inlets 111 and air outlets 112 can be multiple, for example, the number of air inlets 111 can be five, ten, fourteen, eighteen, twenty, thirty, or other numbers, and the number of air outlets 112 can be two, three, four, five, six, or other numbers, and can be set according to actual conditions. This helps to increase the area of the air inlets 111 and air outlets 112, and helps to increase the air intake and air output of the air outlet device 100.

[0038] Among them, the shell 121 can be made of metal material such as aluminum alloy, which helps to improve the heat dissipation efficiency of the shell 121, so that the shell 121 can better dissipate heat for the axial flow fan blades 122, and also helps to increase the structural strength of the shell 121, so that the shell 121 can better protect the axial flow fan blades 122.

[0039] In some embodiments, there are multiple sound absorbing holes 1212 , and the multiple sound absorbing holes 1212 are arranged around the circumference of the shell 121 .

[0040] In this way, the airflow in the shell 121 can be better discharged to the outside of the shell 121 through the multiple sound-absorbing holes 1212, which helps to better reduce the flow resistance of the airflow in the shell 121 to better balance the air pressure inside and outside the shell 121, and helps to reduce the noise generated by the excessive air pressure of the airflow in the shell 121 when the axial flow fan blades 122 are working. It also helps the multiple sound-absorbing holes 1212 to better disperse the noise in the shell 121, which helps to better improve the noise reduction effect of the sound-absorbing holes 1212.

[0041] For example, the number of the sound absorbing holes 1212 may be five, ten, fifteen, twenty, twenty-five, thirty or other numbers, which may be set according to actual conditions.

[0042] In some embodiments, the inner diameter of the sound-absorbing hole 1212 is 0.3 mm to 1 mm. This helps ensure that the sound-absorbing hole 1212 has an appropriate inner diameter, helps ensure the noise reduction effect of the sound-absorbing hole 1212, helps prevent the inner diameter of the sound-absorbing hole 1212 from being too large, helps reduce the situation where noise is directly transmitted to the bracket 11 and hits the inner wall 114 of the bracket 11, generating higher noise, and also helps prevent the inner diameter of the sound-absorbing hole 1212 from being too small, resulting in the sound-absorbing hole 1212 failing to reduce noise.

[0043] For example, the inner diameter of the sound absorbing hole 1212 may be 0.3 mm, 0.35 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or other values, and may be set according to actual conditions.

[0044] Please also refer to Figures 4 to 6 In some embodiments, the air outlet member 12 may further include a sound absorbing member 123, which is sleeved around the outer periphery of the housing 121 and covers the sound absorbing holes 1212. In this way, the sound absorbing holes 1212 can reduce the noise within the housing 121, and the sound absorbing member 123 can absorb the sound waves and energy of the noise within the housing 121, thereby further reducing the noise within the housing 121. This helps to further reduce the noise generated by the air outlet device 100 and improve the user experience.

[0045] The sound absorbing member 123 may be sound absorbing foam, which can better absorb the sound waves and energy of the noise in the shell 121 , thereby helping to better reduce the noise of the air outlet device 100 .

[0046] In some embodiments, the power component 124 is partially located outside the housing 121 and on one side of the air inlet 1211 , the power component 124 is opposite to the air inlet 111 , and the axial flow fan blades 122 are located on one side of the air outlet 1214 .

[0047] In this way, air can enter the housing 121 through the air inlet 111 and the air inlet 1211. Under the action of the axial flow fan blades 122, the air in the housing 121 is blown toward the air outlet 112 through the air supply port 1214, and finally discharged through the air outlet 112. The air inlet 111 can not only meet the air intake requirements, but also reduce the sound waves of the noise generated by the power component 124 during operation, thereby reducing the noise generated by the power component 124, helping to reduce the noise generated by the air outlet device 100, and helping to improve the user experience.

[0048] In some embodiments, the power member 124 is spaced apart from the air inlet 111. This helps reduce the possibility of vibrations from the power member 124 being transmitted to the bracket 11 and generating noise, and also helps reduce the possibility of the power member 124 obstructing the air inlet 111, thereby increasing the air inlet space of the bracket 11 and increasing the air inlet volume of the bracket 11, thereby increasing the air inlet volume of the air outlet device 100.

[0049] Please also refer to Figure 3 、 Figure 5 and Figure 6 In some embodiments, the air outlet device 100 may further include a refrigeration component 13, which is assembled on the bracket 11, the power component 124 is spaced apart from the refrigeration component 13, the air supply port 1214 faces the refrigeration component 13, and the air flow generated by the air outlet component 12 is suitable for blowing from the air supply port 1214 to the refrigeration component 13 and then blowing out from the air outlet 112.

[0050] This helps to ensure the cooling operation of the refrigeration component 13, so that the wind flowing from the air outlet part 12 to the refrigeration component 13 can be cooled when passing through the refrigeration component 13, thereby realizing the output of cold air from the air outlet device 100, and also helps to reduce the vibration of the power part 124 during operation that is transmitted to the refrigeration component 13 to generate noise.

[0051] For example, air can enter the bracket 11 through the air inlet 111 and enter the housing 121 through the air inlet 1211. Under the action of the axial flow fan blades 122, the air in the housing 121 flows through the air outlet 1214 to the cooling assembly 13. The cooling of the cooling assembly 13 causes the surface temperature of the cooling assembly 13 to be relatively low. When the air flows through the cooling assembly 13, the cooling assembly 13 can cool the air and send it out through the air outlet 112, thereby achieving the output of cold air from the air outlet device 100.

[0052] In some embodiments, a fixing portion 113 is provided in the bracket 11 , and the fixing portion 113 is located between the refrigeration assembly 13 and the air inlet 111 . The air outlet member 12 is assembled on the fixing portion 113 , and the air outlet member 12 is spaced apart from the inner wall 114 of the bracket 11 .

[0053] This helps to improve the stability of the air outlet member 12 assembled on the bracket 11, helps to reduce the situation where the air outlet member 12 is loosened from the bracket 11, and helps to reduce the situation where the air outlet member 12 shakes and hits the inner wall 114 of the bracket 11 during operation to generate noise.

[0054] In addition, the fixing portion 113 can also locate the connection position between the air outlet member 12 and the bracket 11, which helps to facilitate the assembly of the air outlet member 12 to the bracket 11, thereby helping to improve the efficiency of assembling the air outlet member 12 to the bracket 11.

[0055] For example, the bracket 11 may include two brackets that can be interlocked to achieve a connection. When the air outlet member 12 needs to be assembled to the bracket 11, the air outlet member 12 can be assembled to the fixing portion 113 of one bracket, and the other bracket can be interlocked with the bracket equipped with the air outlet member 12, thereby completing the assembly of the air outlet member 12.

[0056] In some embodiments, a guide portion 115 may also be provided in the bracket 11, and the guide portion 115 is located between the refrigeration component 13 and the fixed portion 113. The guide portion 115 includes a guide body 1151 and a positioning body 1152. The guide body 1151 is connected to the outer periphery of the positioning body 1152 and is tilted toward the refrigeration component 13. The air outlet piece 12 is assembled on the positioning body 1152. The guide body 1151 is arranged around the outer periphery of the air supply port 1214 and is suitable for guiding the airflow of the air supply port 1214 to the refrigeration component 13.

[0057] Furthermore, the air guide portion 115 is provided at the end of the air outlet member 12, near the axial flow blades 122, for guiding the airflow generated by the fan toward the interior of the bracket 11. Furthermore, the fixing portion 113 is provided between the air guide portion 114 and the air inlet 111, in the middle of the air outlet member 12 or near one end of the power member 124, for supporting the air outlet member 12.

[0058] In this way, the guide body 1151 can guide the airflow generated by the air outlet part 12 to the refrigeration component 13 for heat exchange, so that the airflow can flow toward the refrigeration component 13 in a predetermined direction, which helps to reduce the situation where the airflow flows back to the air inlet 111 and disrupts the airflow at the air inlet 111 to generate noise.

[0059] In addition, the positioning body 1152 can double-fix the air outlet piece 12 together with the fixing portion 113, which helps to better improve the stability of the air outlet piece 12 connected to the bracket 11, and helps to better reduce the noise generated by the air outlet piece 12 shaking and hitting the inner wall 114 of the bracket 11 when working.

[0060] Please also refer to Figures 6 to 10In some embodiments, the refrigeration assembly 13 is disposed within the air outlet device 100. The refrigeration assembly 13 further includes a refrigeration body 131, a support frame 11, first fins 132, and second fins 133. The first fins 133 and the second painted surface 133 are used to transfer the temperature of the refrigeration body 131 outward. The refrigeration body 131 includes a cooling surface 1311 and a heat dissipation surface 1312. The support frame 134 is disposed within the bracket 100, dividing the interior of the bracket 100 into a first air duct 137 and a second air duct 17. The refrigeration body 131 is disposed on the support frame, with the cooling surface 1311 facing the first air duct 137 and thermally connected to the first fins 132. The first fins 132 correspond to the air outlet 112. The heat dissipation surface 1312 is thermally connected to the second fin 133 toward the second air duct 138; the first air duct 137 is connected to the air outlet 1211, and the bracket 11 is also provided with a heat dissipation port 120 connected to the second air duct 138. The second fin 133 is suitable for guiding the airflow generated by the air outlet member 12 from the second air duct 200 to the heat dissipation port.

[0061] In this way, the refrigeration assembly 13 can transfer cold air to the first fins 132 via the cooling surface 1311, so that the first fins 132 can have a lower temperature. When air flows through the first fins 132, the first fins 132 can cool the air and send it out through the first air duct 137 through the air outlet 112, thereby achieving the output of cold air from the air outlet device 100. The refrigeration assembly 13 can also transfer heat to the second fins 133 via the heat dissipation surface 1312, thereby achieving heat exchange on both sides of the refrigeration assembly 13. When air flows through the second fins 133, the air can carry away the heat on the second fins 133 and be discharged through the heat dissipation outlet 120 from the second air duct 138, thereby cooling the heat dissipation surface 1312 side of the refrigeration assembly 13. This also helps to lower the temperature on the side of the air outlet member 12, so that the air outlet member 12 can be kept in a suitable temperature environment. The air outlet member 12 does not need a large air volume to ensure the heat dissipation effect at its location, which helps to reduce the speed of the axial flow fan blades 122 and reduce the generation of noise.

[0062] In addition, the airflow on the side of the first fin 132 can be discharged from the air outlet 112 through the first air duct 137, and the airflow on the side of the second fin 133 can be discharged from the heat dissipation port 120 through the second air duct 138. The airflow on both sides of the refrigeration body 131 can be discharged from the corresponding air ducts respectively. The airflow on both sides of the refrigeration body 131 will not interfere with each other, which helps to reduce the generation of noise.

[0063] The number of the first fins 132 and the second fins 133 can be multiple, which helps to increase the heat exchange area of the first fins 132 and the second fins 133 and helps to improve the heat exchange effect of the refrigeration component 13.

[0064] Re-read Figure 1 and Figure 2In some embodiments, when the air outlet device 100 is a neck-hanging fan, the bracket 11 may include a wearing body 116, a first wearing frame 117, and a second wearing frame 118, wherein the first wearing frame 117 and the second wearing frame 118 are respectively connected to the ends of the wearing body 116. The wearing body 116, the first wearing frame 117, and the second wearing frame 118 may be an integrally molded structure to simplify the structure of the bracket 11 and facilitate manufacturing.

[0065] The wearing body 116, the first wearing frame 117, and the second wearing frame 118 can enclose a neck wearing space 119. When the user wears the air outlet device 100, the user's neck is located in the neck wearing space 119, and the air outlet device 100 can supply air to the neck and / or head of the human body.

[0066] In some embodiments, the first wearing frame 117 and the second wearing frame 118 are both equipped with an air outlet 12 and a cooling assembly 13 , and the first wearing frame 117 and the second wearing frame 118 are both provided with an air inlet 111 and an air outlet 112 .

[0067] In this way, the first wearing frame 117 and the second wearing frame 118 can take in air through the corresponding air inlet 111 and output cold air through the corresponding air outlet 112, which helps to meet the blowing needs of users in different positions and also helps to increase the air output of the air outlet device 100.

[0068] For example, when the user wears the air outlet device 100, the first wearing frame 117 can be located on the right side of the user's neck, and the second wearing frame 118 can be located on the left side of the user's neck. The first wearing frame 117 and the second wearing frame 118 can take in air through the corresponding air inlet 111 and output cold air through the corresponding air outlet 112 to blow air to different parts of the user, so as to better meet the user's needs for blowing air and cooling at different parts of the user.

[0069] In summary, the air outlet device 100 provided by the embodiment of the present invention has a bracket 11 with an air inlet 111 and an air outlet 112. The power member 124 and the axial flow blades 122 of the air outlet device 100 are both assembled on the housing 121, and the drive shaft of the power member 124 is connected to the axial flow blades 122. The shell 121 of the air outlet member 12 is provided with an air inlet 1211, an air supply outlet 1214 and a sound absorption hole 1212. The air inlet 1211 is opposite to the air supply outlet 1214 and the air inlet 1211 and the air supply outlet 1214 are respectively located at two opposite ends of the shell 121. The sound absorption hole 1212 is located on the peripheral side 1213 of the shell 121 and the sound absorption hole 1212 is located between the air inlet 1211 and the air supply outlet 1214. The air inlet 111 is opened at the end of the bracket 11 and is opposite to the air inlet 1211. The axial flow fan blade 122 is suitable for guiding the generated airflow from the air inlet 1211 to the air supply outlet 1214 and blowing it out through the air outlet 112. In this way, the airflow in the shell 121 can be discharged to the outside of the shell 121 through the sound-absorbing holes 1212, which helps to reduce the flow resistance of the airflow in the shell 121, helps to balance the air pressure inside and outside the shell 121, helps to reduce the noise generated by the excessive air pressure of the airflow in the shell 121 when the axial flow fan blades 122 are working, helps to reduce the noise generated by the air outlet device 100, and also helps the sound-absorbing holes 1212 to disperse the noise in the shell 121, helps to reduce the decibels of noise, and helps to improve the user experience.
