[0050] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0051] Please refer to Figures 1 and 2. Figure 1 shows a three-dimensional structural diagram of the neck-hanging air conditioner provided in this embodiment of the present invention, and Figure 2 shows a cross-sectional structural diagram of the neck-hanging air conditioner provided in this embodiment of the present invention. As shown in Figures 1 and 2, the neck-hanging air conditioner includes a housing 100, which includes a neck-hanging part 103 and two handle parts respectively connected to both ends of the neck-hanging part 103. The neck-hanging part 103 and the two handle parts together form a wearing space 10. The housing 100 includes an inner housing 110 facing the wearing space 10 and an outer housing 120 facing away from the wearing space 10. The housing 100 contains a first fan assembly 220 and a temperature regulating assembly 300. In this embodiment of the present invention, the two handle parts are configured as a first handle part 101 and a second handle part 102, which are formed by fastening the inner housing 110 and the outer housing 120.

[0052] In one specific embodiment of this utility model, the housing 100 of the neck-hanging air conditioner is U-shaped, wherein the neck-hanging part 103 can be configured as a flexible neck-hanging part. This utility model embodiment does not impose specific limitations on the shape and structure of the neck-hanging part 103.

[0053] In one alternative embodiment, the first fan assembly 220 and the temperature control assembly 300 are disposed in the neckband 103; in another alternative embodiment, the first fan assembly 220 and the temperature control assembly 300 are respectively housed in each handle portion. In this embodiment of the present invention, the first handle portion 101 and the second handle portion 102 are symmetrically arranged.

[0054] Please refer to Figure 3, which shows an enlarged structural diagram of point A in Figure 2. A first air duct 140 is provided inside the housing 100, and a first air inlet 160 communicating with the first air duct 140 is provided on the housing 100. The temperature regulating component 300 includes a temperature regulating end. A temperature-conducting plate 130 is provided on the first side of the inner housing 110 facing the wearing space 10, and the temperature-conducting plate 130 is thermally connected to the temperature regulating end. The first fan assembly 220 is configured to drive airflow into the housing from the first air inlet 160, and after flowing through the temperature regulating end, flows to the temperature-conducting plate 130. The temperature regulating end is used for cooling or heating. In one specific embodiment of this invention, the temperature regulating end is used for cooling, and the temperature-conducting plate 130 is used for cold compresses.

[0055] This embodiment of the utility model provides a temperature-conducting plate 130 on the first side of the inner shell 110. The temperature-conducting plate 130 is thermally connected to the temperature-regulating end, thereby regulating the temperature of the temperature-conducting plate 310. On the other hand, the first fan assembly 220 is also configured to drive airflow into the first air inlet 160, and after flowing through the temperature-regulating end, it flows to the temperature-conducting plate 130. After the airflow flows through the temperature-regulating end, it forms cold air or hot air. The cold air or hot air flows to the temperature-conducting plate, further improving the temperature regulation effect of the temperature-conducting plate 130. Thus, when the temperature-conducting plate 130 is in contact with human skin, it provides a better cold or hot compress effect.

[0056] In one alternative embodiment, the temperature-conducting plate 130 is located on the handle portion. Specifically, the first handle portion 101 and the second handle portion 102 are respectively provided with temperature-conducting plates near the neck hanging portion 103, that is, the temperature-conducting plate 130 is disposed on the first side near the bending part of the U-shaped shell. In a specific embodiment of this utility model, the temperature-conducting plate 130 can be made of materials with good thermal conductivity such as metal or ceramic, and the inner shell 110 and the outer shell 120 can be made of plastic materials.

[0057] In one optional embodiment, a first air outlet 170 communicating with the first air duct 140 is provided on the first side surface, and the first air outlet 170 is located between the temperature-conducting plate 130 and the end of the handle portion away from the neck hanging portion 103; in another optional embodiment, the first air outlet 170 is provided at one end of the temperature-conducting plate 130 away from the neck hanging portion 103; in yet another optional embodiment, the area on the first side surface between the end of the inner housing 110 and the temperature-conducting plate 130, and the area on the temperature-conducting plate 130 near the end of the inner housing 110, are both provided with first air outlets 170 communicating with the first air duct 140. The first fan assembly 220 is configured to drive airflow into the first air inlet 170, flow through the temperature-regulating end, and then out through the first air outlet 170.

[0058] This embodiment of the invention provides a heat-conducting plate 130 and a first air outlet 170 on the first side of the inner shell 110. With the first air outlet 170 located on the inner shell 110, the heat-conducting plate 130 is relatively short and positioned close to the neck support 103. This allows the heat-conducting plate 130 to fit snugly against the necks of people with different neck sizes, preventing it from detaching when the shell 100 is opened. This ensures that the cooling capacity of the heat-conducting plate 130 is fully utilized, resulting in high surface utilization. The first air outlet 170 is located between the heat-conducting plate 130 and the end of the handle furthest from the neck support 103, providing cooling airflow when the shell 100 is opened, thus meeting the needs of people with different neck sizes. When the first air outlet 170 is located on the temperature-conducting plate 130, the neck air conditioner provided by this utility model can adapt to people with different neck circumferences. For example, when people with small neck circumferences wear it, the temperature-conducting plate 130 can fit against the neck, and the first air outlet 170 is in contact with the skin. At this time, the temperature-conducting plate 130 can achieve contact cooling. When people with large neck circumferences wear it, the shell 100 is stretched open, and the area of ​​the temperature-conducting plate 130 near the neck circumference 103 fits against the neck, while the area of ​​the temperature-conducting plate 130 away from the neck circumference 103 is not in contact with the neck. The first air outlet 170 located on the temperature-conducting plate 130 away from the neck circumference 103 can use the cooling energy of the temperature-conducting plate 130 itself to blow air and cool the neck, thereby improving the utilization rate of the surface of the temperature-conducting plate 130.

[0059] In this embodiment of the utility model, the first handle portion 101 and the second handle portion 102 are symmetrically arranged. Taking the first handle portion 101 as an example, as shown in FIG3, the neck-hanging air conditioner also includes a partition 210 disposed in the first handle portion 101. The partition 210 and the inner shell 110 form a first air duct 140, and the partition 210 and the outer shell 120 form a second air duct 150. The first fan assembly 220 is configured to supply air to the first air duct 140 and the second air duct 150 respectively. The outer shell 120 is provided with a second air outlet communicating with the second air duct 150. The temperature control assembly 30 is also included. The temperature regulating end of the temperature regulating component 300 is located in the first air duct 140, and the heat dissipation end of the temperature regulating component 300 is located in the second air duct 150. The temperature regulating end of the temperature regulating component 300 is used for cooling, and the heat dissipation end is used for heat dissipation. Specifically, the first fan assembly 220 supplies air to the first air duct 140. The air in the first air duct 140 passes through the heat dissipation end of the temperature regulating component 300, carries away the heat from the heat dissipation end of the temperature regulating component 300, and discharges hot air from the first air outlet 170. The first fan assembly 220 supplies air to the second air duct 150. The air in the second air duct 150 passes through the temperature regulating end of the temperature regulating component 300. After being cooled by the temperature regulating end of the temperature regulating component 300, cold air is discharged from the first air outlet 170. In this embodiment of the utility model, the housing is divided into a first air duct 140 and a second air duct 150 by a separator 210. Cold air is delivered through the first air duct 140 and hot air is delivered through the second air duct 150, which can reduce the loss of cold air in the first air duct 140 and improve the heat dissipation and cooling effect.

[0060] The first air outlet 170 includes multiple air holes, which are inclined at a preset angle to the airflow direction in the first air duct 140. Specifically, the multiple air holes are inclined towards the direction from which the airflow blows in the first air duct 140, so that the air in the first air duct 140 can be better discharged from the first air outlet 170, thereby increasing the cold air flow at the first air outlet 170 and better completing the cooling. The preset angle can be set by those skilled in the art according to the actual situation, and this utility model embodiment does not limit it.

[0061] In one optional embodiment, the first side has a first opening 111 communicating with the first air duct 140. The first opening 111 is disposed opposite to the temperature regulating end of the temperature regulating component 300. The temperature-conducting sheet 130 is disposed at the first opening 111 and closes the first opening. Specifically, the temperature-conducting sheet 130 has a limiting structure around its periphery, such as a protruding step structure along the edge of the temperature-conducting sheet 130, for forming a snap-fit ​​engagement with the surface of the inner shell 110 facing away from the wearing space 10 when the temperature-conducting sheet 130 is installed at the first opening 111. In another optional embodiment, the temperature-conducting sheet 130 can be integrally formed with the inner shell 110.

[0062] When the first air outlet 170 is provided at the end of the temperature-conducting plate 130 away from the neck part 103, the area of ​​the temperature-conducting plate 130 near the neck part 103 is in contact with the temperature-regulating end of the temperature-regulating component 300 to conduct the cooling capacity of the temperature-regulating component 300 to the outside. In an optional manner, the temperature-conducting plate 130 is completely in contact with the temperature-regulating end of the temperature-regulating component 300 to make full use of the cooling capacity of the temperature-regulating end.

[0063] In this embodiment of the utility model, the inner shell 110 includes two second sides that bend toward the partition 210 on the first side. The partition 210, the first side, and the two second sides surround to form the first air duct 140. At least one of the second sides is provided with a third air outlet 190 that communicates with the first air duct 140. Preferably, the third air outlet 190 is arranged along the length direction of the inner shell 110.

[0064] Please refer to Figures 4 and 5. Figure 4 shows an exploded view of the first handle portion provided in this embodiment of the present invention, and Figure 5 shows an exploded view of the first handle portion provided in this embodiment of the present invention from another angle. In one optional embodiment, as shown in Figure 4, the surface of the temperature-conducting sheet 130 facing away from the wearing space 10 is provided with a first air guide 131, which is used to guide the air from the first air duct 140 to the third air outlet 190. In another optional embodiment, as shown in Figure 5, the surface of the separator 210 facing the inner shell 110 is provided with a second air guide 211, which is used to guide the air from the first air duct 140 to the third air outlet 190. In yet another optional embodiment, the surface of the temperature-conducting sheet 130 facing away from the wearing space 10 is provided with a first air guide 131, and the surface of the separator 210 facing the inner shell 110 is provided with a second air guide 211. Specifically, the first air guide 131 protrudes from the surface of the temperature-conducting sheet 130 facing away from the wearing space 10, and the first air guide 131 is bent towards the third air outlet 190 to form an arc-shaped air guide plate; the second air guide 211 protrudes from the surface of the separator 210 facing the inner shell 110, and the second air guide 211 is bent towards the third air outlet 190 to form an arc-shaped air guide plate. This embodiment of the invention, through the arrangement of the first air guide 131 and the second air guide 211, can increase the flow of cold air at the third air outlet 190, thereby enabling better cooling.

[0065] In a specific implementation of this utility model embodiment, referring to Figure 4, a first mounting portion 112 for mounting a first fan assembly 220 is provided on the side of the inner shell 110 facing away from the wearing space 10. The first fan assembly 220 is a double-layer centrifugal fan, including a first sub-fan 221 and a second sub-fan 222 disposed opposite to each other. The first air inlet 160 includes a first sub-air inlet 161 disposed on the inner shell 110 and a second sub-air inlet 162 disposed on the outer shell 120. The first sub-fan 221 is configured to drive airflow from the first sub-air inlet 161 into the first air duct 140, and the second sub-fan 222 is configured to drive airflow from the second sub-air inlet 162 into the second air duct 150. Specifically, a partition 113 flush with the separator 210 is provided at the air outlet of the first mounting portion 112. The first sub-fan 221 and the second sub-fan 222 are respectively disposed on both sides of the partition 113 for sending air into the first air duct 140 and the second air duct 150, respectively.

[0066] The neck-mounted air conditioner also includes a second fan assembly 230. The outer casing 120 is provided with a second air inlet 175 that communicates with the second air duct 150. The second fan assembly 230 is used to deliver air from the second air inlet 175 to the second air duct 150. Specifically, the upper side of the separator 210 facing the outer casing 120 is provided with a second mounting part 212 for mounting the second fan assembly 230. The air outlet of the second mounting part 212 communicates with the second air duct 150, and the second air inlet 175 is arranged opposite to the second mounting part 212.

[0067] In one alternative embodiment, the first fan assembly 220 is disposed in the first handle portion 101 near the neck hanger 103, and the second fan assembly 230 is disposed in the end of the first handle portion 101 away from the neck hanger 103; in another alternative embodiment, the second fan assembly 230 is disposed in the first handle portion 101 near the neck hanger 103, and the first fan assembly 220 is disposed in the end of the first handle portion 101 away from the neck hanger 103. Specifically, the inner housing 110 is provided with a first mounting portion 112 near the neck hanger 103, and the separator 210 is provided with a second mounting portion 212 near the end of the inner housing 110. This embodiment of the utility model, by placing the first fan assembly 220 and the second fan assembly 230 on opposite sides inside the handle, can ensure the channel length of the first air duct 140 and the second air duct 150. As a result, the air in the first air duct 140 and the second air duct 150 can carry away more cold and heat, so as to obtain better cooling and heat dissipation effects. In addition, the air is blown and cooled in the second air duct 150 by the oppositely arranged first fan assembly 220 and the second fan assembly 230, so that the second air duct 150 responsible for by the first fan assembly 220 and the second fan assembly 230 is shorter and the heat dissipation effect is better.

[0068] In one specific implementation of this utility model, the temperature regulating component 300 includes a heat dissipation component 320 and a cooling component 310 connected by thermal conduction. The heat dissipation end includes the heat dissipation component 320, which is installed on the side of the separator 210 facing the outer shell 120. The temperature regulating end includes the cooling component 310, which is installed on the side of the separator 210 facing the inner shell 110.

[0069] The heat sink 320 includes a first heat sink 321 and a second heat sink 322 arranged adjacent to each other. The outer casing 120 has a second air outlet 180 at an adjacent position between the first heat sink 321 and the second heat sink 322. The first fan assembly 220 is used to supply air to the first heat sink 321, and the second fan assembly 230 is used to supply air to the second heat sink 322. Specifically, the air supplied by the first fan assembly 220 passes through the first heat sink 321, carrying away the heat of the first heat sink 321, and the hot air is discharged from the second air outlet 180. The air supplied by the second fan assembly 230 passes through the second heat sink 322, carrying away the heat of the second heat sink 322. In a specific implementation of this utility model, both the first heat sink 321 and the second heat sink 322 are provided with multiple fins, and an airflow channel is formed between adjacent fins. When the air from the second air duct 150 passes through the airflow channel, it exchanges heat with the fins, carrying away the heat from the fins.

[0070] This embodiment of the utility model, by placing the second air outlet adjacent to the first radiator 321 and the second radiator 322, can better discharge hot air from the second air outlet at the airflow collision point in the first air duct, thereby improving heat dissipation efficiency.

[0071] In one alternative embodiment, the neck-mounted air conditioner further includes a first temperature-conducting plate 323 and a second temperature-conducting plate 324; the first radiator 321 and the second radiator 322 are respectively thermally connected to the cooling component 310 through the first temperature-conducting plate 323 and the second temperature-conducting plate 324. Specifically, the first radiator 321 is installed on the side of the separator 210 facing the outer casing 120 through the first temperature-conducting plate 323, and the second radiator 322 is installed on the side of the separator 210 facing the outer casing 120 through the second temperature-conducting plate 324.

[0072] Specifically, a third air guide 3231 is provided on the first temperature-conducting plate 323 near the second air outlet 180. Specifically, the first temperature-conducting plate 323 is bent towards the second air outlet 180 to form the third air guide 3231, which is used to guide the hot air passing through the first radiator 321 to the second air outlet 180. A fourth air guide 3241 is provided on the second temperature-conducting plate 324 near the second air outlet 180. Specifically, the second temperature-conducting plate 324 is bent towards the second air outlet 180 to form the fourth air guide 3241, which is used to guide the hot air passing through the second radiator 322 to the second air outlet 180.

[0073] The present invention, through the arrangement of the third air guide 3231 and the fourth air guide 3241, can better discharge hot air from the second air outlet 180.

[0074] In one specific implementation of this utility model, the refrigeration assembly 310 includes a cooler 311, a cooler 312, and a third temperature-conducting plate 313. Specifically, the separator 210 is provided with a second opening 213 for installing the cooler 311. The heat dissipation end of the cooler 311 is thermally connected to the first radiator 321 and the second radiator 322 through the first temperature-conducting plate 323 and the second temperature-conducting plate 324, respectively. The cooling end of the cooler 311 is thermally connected to the cooler 312 through the third temperature-conducting plate 313.

[0075] The cooler 311 can be configured as a semiconductor cooler, which includes a first sub-cooler 3111 and a second sub-cooler 3112. The first sub-cooler 3111 is thermally connected to the first heat sink 321 through a first temperature-conducting plate 323, and the second sub-cooler 3112 is thermally connected to the second heat sink 322 through a second temperature-conducting plate 324.

[0076] In this embodiment of the utility model, the cooler 312 is disposed in the first air duct 140. The cooler 312 is provided with multiple fins, and an airflow channel is formed between two adjacent fins. When the air in the first air duct 140 passes through the airflow channel, it exchanges heat with the fins. That is, the cooler 312 cools and lowers the air passing through the airflow channel by the cooling capacity of the cooling end of the cooler 311, thereby discharging the cold air from the first air outlet 170 and the third air outlet 190.

[0077] In this embodiment of the utility model, the neck air conditioner further includes a battery assembly 240 disposed in the housing 100 for supplying power to the first fan assembly 220, the second fan assembly 230 and the temperature control assembly 300. Preferably, the battery assembly 240 is disposed near the end of the housing 100.

[0078] The housing 100 also includes a circuit board 250 electrically connected to the battery assembly 240, used to control the operation of the first fan assembly 220, the second fan assembly 230 and the temperature control assembly 300.

[0079] The housing 100 is also provided with a charging interface that is electrically connected to the battery assembly 240 for charging the battery assembly 240.

[0080] Please refer to Figure 6. This application embodiment provides a neck air conditioner 1, which can be worn by users around their necks to cool and lower their temperature, freeing up the user's hands and achieving the effect of blowing air and cooling down anytime and anywhere without holding it.

[0081] Please refer to Figures 6 and 7 simultaneously. In this embodiment, the neck-mounted air conditioner 1 may include a housing 100, a cooler 311, and a first fan assembly 220. The housing 100 defines a wearing space 10 for a user to wear, and an installation space 104 is provided inside the housing 100. The housing 100 has a cold air outlet 1432 communicating with the installation space 104. The housing 100 may include an outer shell 120 and a temperature-conducting shell 14. The temperature-conducting shell 14 is connected to the side of the outer shell 120 facing the wearing space 10, and has an air intake 1412. The cooler 311 is disposed within the installation space 104, and the cold side of the cooler 311 is thermally connected to the temperature-conducting shell 14. The first fan assembly 220 is disposed within the installation space 104, with its air inlet side communicating with the air intake 1412 and its air outlet side communicating with the cold air outlet 1432. The term "thermal conduction connection" can be understood as the connection between the two being reflected in thermal conduction. As long as heat transfer is achieved between the two, the "thermal conduction connection" provided in the embodiments of this specification can be considered to have been achieved. Specifically, it can be a contact connection or a non-contact connection. For example, heat transfer can be achieved through direct contact between the surfaces of the two, or through non-contact (space separation) heat transfer via thermal radiation, or through indirect contact (with a reconstructed heat transfer component between the two).

[0082] In use, the cold surface of the cooler 311 transfers cold energy to the temperature-conducting shell 14. Part of the cold energy is conducted to the surrounding air via the temperature-conducting shell 14. The first fan assembly 220 draws the cold air around the temperature-conducting shell 14 into the installation space 104 from the air intake 1412 and blows it out through the cold air outlet 1432, directing it towards the wearer's skin for cooling. The neck-mounted air conditioner 1 of this embodiment uses the temperature-conducting shell 14 to transfer cold energy, improving the efficiency of cold energy transfer. Furthermore, the temperature-conducting shell 14 is positioned on one side of the wearing space 10, achieving a cooling effect close to the wearer's skin. Combined with the cold air supply from the cold air outlet 1432, the cooling effect is greatly enhanced. The air intake 1412 on the temperature-conducting shell 14 collects the cold energy lost in the environment, preventing the cold air from spreading outwards. This relatively efficient utilization of the cold energy on the temperature-conducting shell 14 further improves cooling efficiency and the user experience.

[0083] In this application, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0084] When using the neck-mounted air conditioner 1, the user's neck is located within the wearing space 10. Specifically, the wearing space 10 has an opening on one side to facilitate wearing, and the overall shape of the shell 100 roughly conforms to the curvature of the user's neck, so as to wrap around the user's neck and cool the user's body surface. In this embodiment, the outer shell 120 is curved so that the two ends of the outer shell 120 are spaced apart relative to each other. This specification does not limit the specific shape of the heat-conducting shell 14. The heat-conducting shell 14 can conform to the shape of the outer shell 120 and cover the entire side of the outer shell 120 facing the wearing space 10 (as shown in Figure 7). The two ends of the heat-conducting shell 14 are respectively connected to the two ends of the outer shell 120. The heat-conducting shell 14 defines the wearing space 10, and the thermal conductivity of the heat-conducting shell 14 is higher than that of the outer shell 120.

[0085] Referring to Figures 6 and 8, in some embodiments, the heat-conducting shell 14 may only cover the sides of the outer shell 120 near the back of the user's neck and the sides of the neck, so that the part of the shell 100 in contact with the user can efficiently transfer cold energy, improving cooling efficiency while reducing costs. Specifically, the shell 100 may also include connecting shells 16, with two connecting shells 16 connected to the outer shell 120 and located at both ends of the heat-conducting shell 14, with the two connecting shells 16 spaced apart from each other. The two connecting shells 16 are connected to both ends of the heat-conducting shell 14 and are smoothly connected to the heat-conducting shell 14. The aforementioned "connection" can be understood as the surfaces of the two smoothly transitioning to each other at the adjacent point, such as the connection gap being less than a specified value, or the two being located on the same plane, or the two defining continuous curved surfaces, etc.; or it can be understood as the two jointly forming a specific appearance contour, such as jointly forming a stepped structure, a bend structure, a curved surface structure, etc. In this embodiment, the surface of the connecting shell 16 facing away from the outer shell 120 and the surface of the temperature-conducting shell 14 facing away from the outer shell 120 smoothly transition to each other at the adjacent point, and the two together form a curved structure. The connecting shell 16 and the temperature-conducting shell 14 together define the wearing space 10.

[0086] The temperature-conducting shell 14 protrudes towards the wearing space 10 from the side opposite to the outer shell 120, thus defining the installation space 104 together with the outer shell 120. The temperature-conducting shell 14 has a contact surface 1401 facing the wearing space 10 and a connecting surface 1403 connected to the outer shell 120. Two connecting surfaces 1403 are provided, each located on one side of the contact surface 1401 and connected to one side of the outer shell 120. The two connecting surfaces 1403 are spaced apart from each other and intersect with the contact surface 1401. If the housing 100 also includes the aforementioned connecting shell 16, the connecting shell 16 also protrudes towards the wearing space 10 from the side opposite to the outer shell 120. The outer shell 120, the temperature-conducting shell 14, and the connecting shell 16 together define the installation space 104. The thermal conductivity of the heat-conducting shell 14 is higher than that of the outer shell 120 and also higher than that of the connecting shell 16. For example, the heat-conducting shell 14 can be made of a metal or ceramic material with good thermal conductivity, or it can be made of silicone filled with thermally conductive material to improve the skin-friendly feel of the neck-mounted air conditioner 1. The connecting shell 14 and the outer shell 14 can be made of materials such as plastic or rubber. In some embodiments, the outer shell 120 and the connecting shell 16 can be made of the same material.

[0087] In this embodiment, the temperature-conducting shell 14 is also bent to fit the shape of the outer shell 120. The temperature-conducting shell 14 may include an air inlet 141 and two air outlets 143, which are respectively connected to the two ends of the air inlet 141 and are arranged relatively apart. A cold air outlet 1432 is disposed on the air outlet 143, and an air intake 1412 is disposed on the side of the air inlet 141 facing the wearing space 10. When the user wears the neck air conditioner 1, the air inlet 141 is opposite to the back of the user's neck, and the two air outlets 143 are located on both sides of the user's neck. Specifically, in this embodiment, the air intake 1412 is disposed on the contact surface 1401 of the air inlet 141. When the neck air conditioner 1 is turned on, the first fan assembly 220 draws air through the air intake 1412, and the air flows between the contact surface 1401 and the wearer's body surface, which has a certain cooling effect on the back of the user's neck. A cold air outlet 1432 is located on the connecting surface 1403 of the air outlet 143. When the user wears the device, the cold air outlet 1432 is located on the connecting surface 1403 on the upper side of the neck-mounted air conditioner 1. The connecting surface 1403 is inclined toward the wearing space 10 so that the air blown from the cold air outlet 1432 can blow toward the user's body surface, such as the head and neck area.

[0088] Please refer to Figure 7 again. Two cold air outlets 1432 can be provided, each located on one of the two air outlets 143. This specification does not limit the shape of the cold air outlets 1432; they can be round or square. In this embodiment, the cold air outlets 1432 are strip-shaped vents extending along the arc of the thermally conductive shell 14, so that the range of cold air blowing out is relatively large. To reduce the possibility of foreign objects entering the housing 100 under the suction force of the first fan assembly 220 when it starts, the air intake 1412 can include multiple small-diameter round holes, arranged at approximately even intervals. In actual production, the arrangement and specific shape of the air intake 1412 can be designed according to the contour of the air inlet side of the first fan assembly 220.

[0089] In some embodiments, the cold air outlet 1432 may also be provided on the outer shell 120 or the connecting shell 16; or, the outer shell 120 and the temperature-conducting shell 14 may both be provided with cold air outlets 1432, and the connecting shell 16 and the temperature-conducting shell 14 may both be provided with cold air outlets 1432; in other embodiments, the cold air outlet 1432 may also be a gap between the outer shell 120 and the temperature-conducting shell 14.

[0090] In this embodiment, the cooler 311 is disposed on the temperature-conducting shell 14 and is used to output cooling capacity. The cooler 311 is connected to the inner wall corresponding to the contact surface 1401 of the air inlet 141, and is closer to the wearing space 10, resulting in a relatively better cooling effect. The cooler 311 can be a semiconductor cooler, which utilizes the thermoelectric effect for cooling. The heat absorption and release phenomena generated when current passes through different conductors achieve the cooling effect. The cooler 311 has a hot surface and a cold surface, where the hot surface is understood as the side of the cooler 311 that releases heat, and the cold surface is understood as the side of the cooler 311 that absorbs heat. The cold surface of the cooler 311 is in contact with the temperature-conducting shell 14. When the neck air conditioner 1 is turned on, the cold surface of the cooler 311 absorbs heat, thereby reducing the temperature around the neck air conditioner 1 and making the wearer feel cool. The cooler 311 and the temperature-conducting shell 14 are close to the wearer's skin, which can not only effectively reduce the local temperature, but also transmit the cooling sensation to the whole body through blood circulation.

[0091] Please refer to Figures 7 and 9 simultaneously. The first fan assembly 220 is disposed within the installation space 104 and located between the air inlet 141 and the outer casing 120. The first fan assembly 220 is located at the end of the cooler 311, and the air inlet side of the first fan assembly 220 is connected to the air intake 1412. The first fan assembly 220 can be a centrifugal first fan assembly, with the airflow direction of the centrifugal first fan assembly being the axial direction and the airflow direction of the first fan assembly 220 being the radial direction. In this embodiment, the neck-mounted air conditioner 1 also includes an air guide shell 70 disposed within the installation space 104. The air guide shell 70 has a communicating air inlet channel 701 and an air guide channel 703. The first fan assembly 220 is disposed within the air inlet channel 701, and the air intake 1412 and the cold air outlet 1432 are connected sequentially through the air inlet channel 701 and the air guide channel 703. The air guide shell 70 forms an air duct between the air intake 1412 and the cold air outlet 1432, which gathers the air blown out by the first fan assembly 220 and guides it to the cold air outlet 1432, thereby improving the cooling efficiency.

[0092] In this embodiment, the air guide shell 70 may include a volute 72, a volute tongue 74, and an air guide plate 76. The volute 72 surrounds to form an air inlet channel 701 and has a third opening 721. The volute tongue 74 is connected to the volute 72 and located at the third opening 721. One end of the air guide plate 76 is connected to the third opening 721 of the volute 72, and the other end extends to the cold air outlet 1432 of the temperature guide shell 14. The air guide plate 76 and the volute 72 are spaced apart to form an air guide channel 703. The first fan assembly 220 is a turbine first fan assembly, and the first fan assembly 220 discharges air radially. The first fan assembly 220 is disposed in the air inlet channel 701, and the volute 72 surrounds the outer periphery of the first fan assembly 220. The surrounding volute structure further improves the effect of collecting and guiding airflow.

[0093] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0094] The volute 72 and volute tongue 74 can both be disposed in the air inlet 141, and the air guide plate 76 can be disposed in the air outlet 143. One end of the volute tongue 74 is connected to one side of the third opening 721 of the volute 72, and the other end is connected to the inner wall of the heat-conducting shell 14 on the side where the cold air outlet 1432 is located. One end of the air guide plate 76 is connected to the other side of the third opening 721 of the volute 72, so that the third opening 721 is located between the volute tongue 74 and the air guide plate 76. The air guide plate 76 is inclined, so that the end away from the volute 72 extends to the side wall where the cold air outlet 1432 is located, so that the cold air outlet 1432 is located between the end of the volute tongue 74 away from the volute 72 and the end of the air guide plate 76 away from the volute 72. The air guide shell 70, the outer shell 120, and the heat-conducting shell 14 together define the air inlet channel 701 and the air guide channel 703. When the first fan assembly 220 is started, the air is blown out from the side of the first fan assembly 220, collected and gathered by the volute 72, and enters the air guide channel 703 through the third opening 721, and is then blown out from the cold air outlet 1432, which improves the air outlet efficiency and thus improves the cooling efficiency.

[0095] To further improve cooling efficiency, in this embodiment, the neck-mounted air conditioner 1 also includes cooling fins 80, which are disposed within the air duct 703. The cooling fins 80 are connected between the outer casing 120 and the air outlet 143, and are thermally connected to the air outlet 143. Since the cooling fins 80 are in contact with the temperature-conducting shell 14, they transfer the cooling energy transferred from the cooler 311 through the temperature-conducting shell 14. The cooling fins 80 further cool the air within the air duct 703, thereby relatively improving cooling efficiency, and also increasing the contact area between the temperature-conducting shell 14 and the cold air, thus improving cooling efficiency.

[0096] Multiple cooling fins 80 are provided, each extending along the direction of the air guide channel 703. These fins are spaced apart within the channel, forming a flow channel 801 between adjacent fins. One end of the flow channel 801 is connected to the cold air outlet 1432. The multiple cooling fins 80 further improve the cooling effect. One end of each fin is located at the third opening 721, and the other end is located at the cold air outlet 1432. The fins are arranged approximately along the width of the air guide channel 703. The multiple flow channels 801 divert and guide the cold air, and adjacent fins 80 cool the air within their respective flow channels 801, further improving cooling efficiency. In actual production, the number of cooling fins 80 can be adjusted according to the length of the cold air outlet 1432.

[0097] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0098] In this embodiment, two first fan assemblies 220 and two air guide shells 70 are provided. The two air guide shells 70 are respectively disposed at both ends of the cooler 311, and the two first fan assemblies 220 are respectively disposed in the air inlet channels 701 of the two air guide shells 70. Correspondingly, two air intakes 1412 are also provided. The two air intakes 1412 are arranged at intervals in the air inlet 141 and are corresponding one-to-one with the first fan assemblies 220. The air intakes 1412 are connected to the air inlet side of the corresponding first fan assembly 220. The two first fan assemblies 220 and the two air guide shells 70 make the airflow from both sides of the neck air conditioner 1 larger and more uniform, further improving the user experience.

[0099] The cooling fins 80 can also be provided in two sets. Each set of cooling fins 80 includes multiple cooling fins 80. The two sets of cooling fins 80 are arranged one-to-one with the two air guide shells 70. Each set of cooling fins 80 is located in the air guide channel 703 of the corresponding air guide shell 70.

[0100] In this embodiment, the neck-mounted air conditioner 1 may further include a heat dissipation component 320, which is disposed within the installation space 104 and is thermally connected to the hot surface of the cooler 311. The heat dissipation component 320 is used to dissipate heat from the hot surface of the cooler 311, thereby improving cooling efficiency.

[0101] Please refer to Figures 7, 9, and 10 simultaneously. The heat sink 320 has a heat dissipation channel 92 and is positioned between the two first fan assemblies 220. To save space and increase heat dissipation efficiency, both ends of the heat sink 320 can have arc-shaped recesses that contact the heat sink 320, adapting to the shape of the volute 72. The volute 72 is partially embedded in the arc-shaped recesses at the ends of the heat sink 320. The volute 72 has a fourth opening 723, which, along with the third opening 721, is located on both sides of the volute 72. The outer casing 120 also has a fourth opening 180, which is connected to the fourth opening 180 via the heat dissipation channel 92. Part of the air blown out by the first fan assembly 220 enters the air guide channel 703 through the third opening 721 and exits from the cold air outlet 1432, while the other part enters the heat dissipation channel 92 through the fourth opening 723 and exits from the fourth opening 180, thus improving the heat dissipation efficiency of the heat sink 320.

[0102] In this embodiment, two heat dissipation channels 92 can be provided, with each channel corresponding to one of the two air guide shells 70. Each heat dissipation channel 92 has a first end 921 and a second end 923. The first end 921 is connected to the air inlet channel 701 of the corresponding air guide shell 70, while the second end 923 is closed. Air blown from the two first fan assemblies 220 through their respective fourth openings 723 passes through the corresponding heat dissipation channels 92 and exits through the fourth opening 180, further improving the heat dissipation efficiency of the heat sink 320.

[0103] The heat dissipation channel 92 extends approximately along the length of the air inlet 141, and the two heat dissipation channels 92 are arranged side by side along the width of the air inlet 141. For ease of description, the two heat dissipation channels 92 can be designated as a first heat dissipation channel and a second heat dissipation channel, arranged side by side. The first end 921 of the first heat dissipation channel and the second end 923 of the second heat dissipation channel are located at the same end of the heat sink 320, and the second end 923 of the first heat dissipation channel and the first end 921 of the second heat dissipation channel are also located at the same end of the heat sink 320. The fourth opening 180 is located at the corresponding position of the outer shell 120 and the heat sink 320. The first end 921 of the heat dissipation channel 92 connects to the corresponding air inlet channel 701, and the second end 923 is closed. The heat dissipation channel 92 changes the airflow direction of the fourth opening 723, allowing heat to be discharged through the side of the outer shell 120 away from the wearing space 10, improving heat dissipation efficiency while preventing hot air from blowing towards the wearer, thus improving the user experience.

[0104] The fourth opening 180 may include multiple small-diameter circular holes, which are arranged at approximately uniform intervals. There may be two sets of fourth openings 180, with each set corresponding to the second end 923 of one of the two heat dissipation channels 92.

[0105] Please refer to Figures 10 and 11 simultaneously. In this embodiment, the heat dissipation channel 92 may include multiple sub-channels 925 arranged in parallel. The bottom wall of each sub-channel 925 is provided with a guide arc surface 9252, which causes the depth of the heat dissipation channel 92 to decrease from the first end 921 to the second end 923. Multiple fins may be provided within the heat dissipation channel 92, and these fins are spaced apart along the width direction of the air inlet 141, dividing the heat dissipation channel 92 into multiple sub-channels 925. The multiple sub-channels 925 increase the contact area between the airflow and the heat sink 320, improving the heat dissipation effect. The guide arc surface 9252 guides the airflow within the heat dissipation channel 92, preventing turbulent airflow and improving heat dissipation stability.

[0106] When the neck-mounted air conditioner 1 provided in this embodiment is in use, the cold surface of the cooler 311 transfers cold energy to the temperature-conducting shell 14. Part of the cold energy is conducted to the surrounding air through the temperature-conducting shell 14. The first fan assembly 220 draws the cold air around the temperature-conducting shell 14 into the installation space 104 from the air intake 1412 and blows it out through the cold air outlet 1432, directing it towards the wearer's skin to cool and lower the temperature. The neck-mounted air conditioner 1 in this embodiment uses the temperature-conducting shell 14 to transfer cold energy, improving the efficiency of cold energy transfer. Furthermore, the temperature-conducting shell 14 is positioned on one side of the wearing space 10, achieving a cooling effect close to the wearer's skin. Combined with the cold air supply from the cold air outlet 1432, the cooling effect is greatly improved. The air intake 1412 on the temperature-conducting shell 14 collects the cold energy lost in the environment, preventing the cold air from spreading outwards. This relatively efficient utilization of the cold energy on the temperature-conducting shell 14 further improves cooling efficiency and the user experience.

[0107] Please refer to Figures 12 to 20. An embodiment of this utility model provides a neck-mounted air conditioner 1, which is worn around the user's neck for use, so as to blow airflow toward the user's neck or head to create a cooling effect.

[0108] The neck-mounted air conditioner 1 includes a housing 100, a temperature regulating component 300, and a fan component 17. The housing 100 forms a wearing space 10, through which the neck-mounted air conditioner 1 can be worn around the neck. The temperature regulating component 300 and the fan component 17 are respectively disposed inside the housing 100. The temperature regulating component 300 can cool, while the fan component 17 drives outside air into the housing 100 and through the temperature regulating component 300. After the temperature regulating component 300 cools the passing air, the fan component 17 drives the airflow to blow towards the user, creating a cooling effect, reducing the impact of the outside ambient temperature on the cooling effect of the neck-mounted air conditioner 1, and improving the cooling effect of the neck-mounted air conditioner 1.

[0109] The housing 100 is preferably made of a flexible material such as silicone to ensure wearing comfort and allow the housing 100 to deform to a certain extent to adjust the size of the wearing space 10, so that the neck air conditioner 1 can better adapt to different users.

[0110] The housing 100 includes a neckband 103 and handles 22 connected to both ends of the neckband 103. The two handles 22 and the neckband 103 together form a wearing space 10. The temperature control component 300 is located inside the neckband 103, and the fan component 17 is located inside the neckband 103 and / or the handles 22. During use, the user can grasp the handles 22 with both hands and then wear the neckband air conditioner 1 around the neck. After the neckband air conditioner 1 is worn around the neck, the neckband 103 is located on the back of the neck, and the two handles 22 are located on opposite sides of the neck.

[0111] Understandably, the neckband 103 and the two handles 22 can be integrally formed or assembled separately.

[0112] The temperature control component 300 includes a cooler 311 and a cooler conductor 312 and a heat sink 320 respectively connected to opposite sides of the cooler 311. Specifically, the cooler conductor 312 is located on the side of the cooler 311 closer to the wearing space 10, and the heat sink 320 is located on the side of the cooler 311 away from the wearing space 10. When the cooler 311 is working, its side closer to the wearing space 10 serves as the cooling end and generates cold energy, while its side away from the wearing space 10 serves as the heat generating end and generates heat. The cold energy generated by the cooler 311 can be transferred to the cooler conductor 312, causing the temperature of the cooler conductor 312 to decrease. The generated heat is then transferred to the heat sink 320, causing the overall temperature of the cooler 311 to decrease, while the overall temperature of the heat sink 320 to increase. The heat sink 320 has a large contact area with the air, resulting in better heat dissipation. The cooler 311 uses the heat sink 320 to assist in heat dissipation, promptly transferring the heat generated on the side of the cooler 311 away from the wearing space 10, thus ensuring the heat dissipation effect of the cooler 311.

[0113] In this application, the cooler 311 is a semiconductor cooler, which is generally plate-shaped, and the cooler 312 and the heat sink 320 are respectively attached and fixed to the opposite sides of the semiconductor cooler.

[0114] The housing 100 is provided with a first sub-air duct 140, a first air inlet 160 and a first air outlet 170 communicating with the first sub-air duct 140, a second sub-air duct 150, and a second air inlet 175 and a second air outlet 180 communicating with the second sub-air duct 150. The cooler 312 is located in the first sub-air duct 140, the heat sink 320 is located in the second sub-air duct 150, and the fan assembly 17 includes a blower located in the first sub-air duct 140 and a second fan assembly 230 located in the second sub-air duct 150. When the blower is working, it draws outside air into the first sub-duct 140 through the first air inlet 160 and drives the airflow to flow towards the first air outlet 170 within the first sub-duct 140. During its flow within the first sub-duct 140, the airflow passes through the cooler 312 and exchanges heat with it. Because the cooler 312 has a lower temperature, the airflow cools down after heat exchange. The cooled airflow then blows towards the user from the first air outlet 170, creating a cooling effect and reducing the impact of the ambient temperature on the cooling effect of the neck air conditioner 1, thus improving the cooling effect of the neck air conditioner 1 on the user. When the second fan assembly 230 is working, it draws outside air through the second air inlet... The airflow is drawn into the second sub-air duct 150 through the inlet 175 and directed towards the second outlet 180 within the second sub-air duct 150. During its flow within the second sub-air duct 150, the airflow passes through the heat sink 320 and exchanges heat with it. Since the heat sink 320 is at a high temperature, the airflow can carry away the heat from the heat sink 320 as it passes through it, and then exits from the second outlet 180. After the heat on the heat sink 320 is carried away by the airflow, its temperature decreases, allowing the heat generated by the cooler 311 on the side away from the wearing space 10 to be quickly transferred to the heat sink 320, ensuring the cooling effect of the cooler 311 and ensuring the cooling effect of the cooler 312 on the passing airflow.

[0115] The specific locations of the first air inlet 160 and the first air outlet 170 are not limited, and they can be located on the same side of the housing 100 or on different sides of the housing 100. For example, the first air inlet 160 can be located on the side of the housing 100 that is close to or far from the wearing space 10, or it can be located on the side of the housing 100 in its height direction. The first air outlet 170 can be located on the side of the housing 100 that is close to the housing 100, or it can be located on the side of the housing 100 in its height direction, as long as it can blow air towards the user.

[0116] In this application, the height direction of the housing 100 refers to the height direction when the housing 100 is worn on the human body. Specifically, the housing 100 has a non-closed annular structure, and the height direction of the housing 100 is also the axial direction of the wearing space 10.

[0117] Preferably, the second air inlet 175 and the second air outlet 180 are both located on the side of the housing 100 away from the wearing space 10, to prevent hot air after heat exchange with the heat sink 320 from blowing towards the user.

[0118] The first sub-air duct 140 and the second sub-air duct 150 are located on opposite sides of the cooler 311 at the temperature control component 300. That is, the first sub-air duct 140 is located on the side of the cooler 311 closer to the wearing space 10 in the area of ​​the temperature control component 300, and the second sub-air duct 150 is located on the side of the cooler 311 away from the wearing space 10 in the area of ​​the temperature control component 300. The first sub-air duct 140 and the second sub-air duct 150 are separated by the cooler 311 at the temperature control component 300, which reduces the risk of mutual interference between the cold air in the first sub-air duct 140 and the hot air in the second sub-air duct 150, thereby reducing the impact of the hot air in the second sub-air duct 150 on the cooling effect of the cold air on the user.

[0119] Specifically, the neck hanger 103 is provided with a mounting bracket 44, which is ring-shaped. The cooler 311 is fixedly installed on the inner side of the mounting bracket 44, thereby indirectly fixing it to the housing 100. The mounting bracket 44 surrounds the outer periphery of the cooler 311, which can also, to a certain extent, separate the second sub-air duct 150 and the first sub-air duct 140, further reducing the risk of mutual interference between cold and hot air.

[0120] In one embodiment, the first sub-duct 140 includes a first sub-duct 46 and a second sub-duct 48. The blower includes a first blower 50 located in the first sub-duct 46 and a second blower 52 located in the second sub-duct 48. The cooler 312 is partially located in the first sub-duct 46 and partially located in the second sub-duct 48. The first blower 50 can drive airflow within the first sub-duct 46, and the second blower 52 can drive airflow within the second sub-duct 48. This increases the air intake and exhaust volume of the neck-mounted air conditioner 1. Furthermore, the airflow passes through the cooler 312 to reduce temperature when flowing within both the first and second sub-ducts 46 and 48.

[0121] Understandably, the first sub-duct 46 and the second sub-duct 48 can have separate outlets and inlets, or they can have the same outlet or inlet.

[0122] In this embodiment, the first air inlet 160 includes a first inlet 54 and a second inlet 56, and the first air outlet 170 includes a first outlet 58 and a second outlet 60. The first inlet 54 and the first outlet 58 are respectively connected to both ends of the first sub-air duct 46, and the second inlet 56 and the second outlet 60 are respectively connected to both ends of the second sub-air duct 48. The first blower 50 is located between the first inlet 54 and the first outlet 58, and the second blower 52 is located between the second inlet 56 and the second outlet 60. When the first blower 50 is working, outside air enters the first sub-duct 46 through the first inlet 54 and flows towards the first outlet 58 within the first sub-duct 46. During this flow, it passes through the portion of the cooler 312 located within the first sub-duct 46, where its temperature is lowered, before being discharged from the first outlet 58 and blown towards the user. When the second blower 52 is working, outside air enters the second sub-duct 48 through the second inlet 56 and flows towards the second outlet 60 within the second sub-duct 48. During this flow, it passes through the portion of the cooler 312 located within the second sub-duct 48, where its temperature is lowered, before being discharged from the second outlet 60 and blown towards the user. This allows the neck air conditioner 1 to draw in air from different inlets and blow cool air towards the user from different outlets, increasing the air intake volume of the neck air conditioner 1 and simultaneously increasing the coverage area of ​​the cool air on the human body, i.e., increasing the contact area between the cool air and the human body, thereby enhancing the cooling effect of the neck air conditioner 1.

[0123] The first blower 50 and the second blower 52 are located on opposite sides of the cooler 312, that is, the cooler 312 is located between the first blower 50 and the second blower 52. The direction in which the airflow driven by the first blower 50 passes through the cooler 312 is opposite to the direction in which the airflow driven by the second blower 52 passes through the cooler 312. By installing the first blower 50 and the second blower 52 on opposite sides of the cooler 312 and making the air driven by the first blower 50 and the second blower 52 pass through the cooler 312 in opposite directions, the layout of the first blower 50 and the second blower 52 is more reasonable, improving the compactness of the internal structure of the neck-mounted air conditioner 1, and preventing the problem of excessively large local dimensions of the neck-mounted part 103 caused by placing the first blower 50 and the second blower 52 on the same side of the cooler 312.

[0124] Specifically, the first inlet 54 and the second inlet 56, as well as the first outlet 58 and the second outlet 60, are located on opposite sides of the cooler 312. The inlets of the first sub-duct 46 and the second sub-duct 48 are located on opposite sides of the cooler 312, and the outlets of the first sub-duct 46 and the second sub-duct 48 are also located on opposite sides of the cooler 312. This increases the distance between the first inlet 54 and the second inlet 56, as well as between the first outlet 58 and the second outlet 60. This prevents the distance between the two inlets from being too small, which would cause the air to interfere with each other and affect the air intake. At the same time, it also avoids the distance between the two outlets from being too small, which would cause the cold air coverage area to overlap and affect the cooling effect.

[0125] Preferably, the cooler 312 is located between the first blower 50 and the second blower 52, and the cooler 312 is located in the middle of the neck hanger 103. The first blower 50 and the second blower 52 are respectively located at both ends of the neck hanger 103 near the handle 22, so as to avoid the first blower 50, the second blower 52 and the cooler 312 being too concentrated in the neck hanger 103, which facilitates disassembly and assembly, and also facilitates the design of the first sub-air duct 46 and the second sub-air duct 48.

[0126] The first sub-air duct 46 and the second sub-air duct 48 are offset along the height direction of the housing 100 at the cooler duct 312. Since the direction of airflow through the cooler duct 312 in the first sub-air duct 46 is opposite to the direction of airflow through the cooler duct 312 in the second sub-air duct 48, the first sub-air duct 46 and the second sub-air duct 48 are offset along the height direction of the housing 100. This reduces the mutual impact of airflow in the first sub-air duct 46 and the second sub-air duct 48 at the cooler duct 312, thereby reducing the air volume output of the neck air conditioner 1.

[0127] In one embodiment, the first inlet 54 and the second inlet 56 are respectively located on the side of the neckband 103 near the wearing space 10. The first inlet 54 is located on the side of the cooler 312 away from the first blower 50, and the second inlet 56 is located on the side of the cooler 312 away from the second blower 52. That is, the first blower 50, the second inlet 56, the cooler 312, the first inlet 54, and the second blower 52 are arranged at intervals along the circumference of the housing 100. The second inlet 56 is located between the first blower 50 and the cooler 312, and the first inlet 54 is located between the second blower 52 and the cooler 312. In other words, the first inlet 54 and the second blower 52 are located on the same side of the cooler 312, and the second inlet 56 is located on the same side of the cooler 312 as the first blower 50. When the first blower 50 is working, outside air enters the first sub-duct 46 through the first inlet 54, moves from one side of the cooler 312 to the opposite side, and then exits from the first outlet 58 after passing through the first blower 50. When the second blower 52 is working, outside air enters the second sub-duct 48 through the second inlet 56, moves from one side of the cooler 312 to the opposite side, and then exits from the second outlet 60 after passing through the second blower 52, so that the airflow driven by the first blower 50 and the second blower 52 can both fill the airway. The airflow is in contact with the cooler 312, enhancing the heat exchange between the airflow and the cooler 312 and ensuring the cooling effect of the neck air conditioner 1. Moreover, the first blower 50 is located on the side of the cooler 312 near the first outlet 58, and the second blower 52 is located on the side of the cooler 312 near the second outlet 60. This reduces the distance between the first blower 50 and the first outlet 58 and the second blower 52 and the second outlet 60, so that the cold air blown out from the first outlet 58 and the second outlet 60 has stronger power, ensuring that the cold air can reach the user after it is blown out.

[0128] Preferably, the first inlet 54 and the second inlet 56 are staggered in the height direction of the housing 100, so that the two airflows entering the first sub-air duct 46 and the second sub-air duct 48 are staggered when they enter, which helps to reduce the difficulty of setting up the first sub-air duct 46 and the second sub-air duct 48.

[0129] Specifically, the first outlet 58 is located on the side of the first blower 50 away from the cooler 312, the second outlet 60 is located on the side of the second blower 52 away from the cooler 312, and the first outlet 58 and the second outlet 60 are respectively located on one side of the two handle portions 22 in the height direction of the housing 100.

[0130] In this embodiment, the neckpiece 103 is provided with a first guide section 62 and a second guide section 64. The first guide section 62 and the second guide section 64 are located on opposite sides of the cooler 312. The first guide section 62 extends from the first inlet 54 toward the cooler 312, and the second guide section 64 extends from the second inlet 56 toward the cooler 312. After passing through the first inlet 54, the outside air comes into contact with the first guide section 62 and moves toward the cooler 312 under the guidance of the first guide section 62, eventually moving from one side of the cooler 312 to the other opposite side. Similarly, after passing through the second inlet 56, the outside air comes into contact with the second guide section 64 and moves toward the cooler 312 under the guidance of the second guide section 64, eventually moving from one side of the cooler 312 to the other opposite side. This serves to guide the airflow into the first sub-duct 46 and the second sub-duct 48 to increase the air intake volume.

[0131] Specifically, one end of the first flow guide 62 is connected to the neck hanger 103 and the connection point is located on the side of the first inlet 54 away from the cooler 312, while the other end extends obliquely toward the side of the cooler 312. The first inlet 54 is located between the cooler 312 and the first flow guide 62. One end of the second flow guide 64 is connected to the neck hanger 103 and the connection point is located on the side of the second inlet 56 away from the cooler 312, while the other end extends obliquely toward the opposite side of the cooler 312. The second inlet 56 is located between the cooler 312 and the second flow guide 64. The first flow guide 62 and the second flow guide 64 are offset in the height direction of the housing 100.

[0132] A first clearance portion 66 is provided on one side of the cooler 312 corresponding to the first flow guide portion 62, and the first flow guide portion 62 is inserted into the first clearance portion 66. On the other opposite side of the cooler 312, a second clearance portion 68 is provided corresponding to the second flow guide portion 64, and the second flow guide portion 64 is inserted into the second clearance portion 68. Both the first clearance portion 66 and the second clearance portion 68 are notched, and are offset in the height direction of the housing 100. Outside air enters the notched first clearance portion 66 under the guidance of the first flow guide portion 62 after passing through the first inlet 54, and then flows along the first sub-air duct 46. Outside air enters the notched second clearance portion 68 under the guidance of the second flow guide portion 64 after passing through the second inlet 56, and then flows along the second sub-air duct 48. This reduces the diffusion of airflow to the surroundings after passing through the first inlet 54 and the second inlet 56, thereby increasing the air intake of the first sub-air duct 46 and the second sub-air duct 48.

[0133] Specifically, the outer contour of the cooler 312 is roughly rectangular, and the first clearance portion 66 and the second clearance portion 68 are notches located at the two corners of the rectangle on a diagonal line, thereby creating a misalignment effect.

[0134] In another embodiment, the first outlet 58 and the second outlet 60 are respectively located on the side of the neckband 103 near the wearing space 10. The first outlet 58 is located on the side of the cooler 312 away from the first blower 50, and the second outlet 60 is located on the side of the cooler 312 away from the second blower 52. That is, the first blower 50, the second outlet 60, the cooler 312, the first outlet 58, and the second blower 52 are arranged at intervals along the circumference of the housing 100. The second outlet 60 is located between the first blower 50 and the cooler 312, and the first outlet 58 is located between the second blower 52 and the cooler 312. In other words, the first outlet 58 and the second blower 52 are located on the same side of the cooler 312, and the second outlet 60 and the first blower 50 are located on the same side of the cooler 312. When the first blower 50 and the second blower 52 are working, they can both move the airflow from one side of the cooler 312 to the other side, so that the airflow can fully contact the cooler 312 to enhance the heat exchange effect between the airflow and the cooler 312. Moreover, the first blower 50 is located on the side of the cooler 312 away from the first outlet 58, and the second blower 52 is located on the side of the cooler 312 away from the second outlet 60, which reduces the distance between the first blower 50 and the first inlet 54 and the second blower 52 and the second inlet 56. This allows the first blower 50 and the second blower 52 to form a greater suction force at the first inlet 54 and the second inlet 56 to increase the air intake volume.

[0135] Preferably, the first outlet 58 and the second outlet 60 are offset in the height direction of the housing 100, so that the airflows blown from the first outlet 58 and the second outlet 60 are offset from each other in the height direction, so as to contact the user's skin at different heights, thereby increasing the coverage area of ​​the cold air on the human body.

[0136] Specifically, the first inlet 54 and the second inlet 56 are both located on the side of the neckband 103 away from the wearing space 10. The first inlet 54 and the second inlet 56 are arranged at intervals along the circumference of the housing 100. The first inlet 54 is close to the first blower 50, and the second outlet 60 is close to the second blower 52.

[0137] In this embodiment, the neckpiece 103 is provided with a first guide section 62 and a second guide section 64. The first guide section 62 and the second guide section 64 are located on opposite sides of the cooler 312. The first guide section 62 extends from the first outlet 58 toward the cooler 312, and the second guide section 64 extends from the second outlet 60 toward the cooler 312. When the airflow in the first sub-duct 46 moves from the side of the cooler 312 away from the first outlet 58 to the first guide section 62, the first guide section 62 can guide the airflow toward the first outlet 58. When the airflow in the second sub-duct 48 moves from the side of the cooler 312 away from the second outlet 60 to the second guide section 64, the second guide section 64 can guide the airflow toward the second outlet 60, thereby guiding the airflow to blow outward from the first outlet 58 and the second outlet 60 to increase the airflow volume.

[0138] Specifically, one end of the first guide section 62 is connected to the neck section 103 and the connection point is located on the side of the first outlet 58 away from the cooler 312, and the other end extends obliquely toward the side of the cooler 312. The first outlet 58 is located between the cooler 312 and the first guide section 62. One end of the second guide section 64 is connected to the neck section 103 and the connection point is located on the side of the second outlet 60 away from the cooler 312, and the other end extends obliquely toward the opposite side of the cooler 312. The second outlet 60 is located between the second guide section 64 and the cooler 312. The first guide section 62 and the second guide section 64 are offset in the height direction of the housing 100.

[0139] A first clearance portion 66 is provided on one side of the cooler 312 corresponding to the first flow guide portion 62, and the first flow guide portion 62 is inserted into the first clearance portion 66. On the other opposite side of the cooler 312, a second clearance portion 68 is provided corresponding to the second flow guide portion 64, and the second flow guide portion 64 is inserted into the second clearance portion 68. Both the first clearance portion 66 and the second clearance portion 68 are notched, and the first clearance portion 66 and the second clearance portion 68 are offset in the height direction of the housing 100. The airflow in the first sub-air duct 46 is guided by the first flow guide portion 62 and first enters the notched first clearance portion 66, and then is blown out from the first outlet 58. The airflow in the second sub-air duct 48 is guided by the second flow guide portion 64 and first enters the notched second clearance portion 68, and then is blown out from the second outlet 60. This reduces the diffusion of airflow to the surroundings when it is blown out from the first outlet 58 and the second outlet 60, thereby increasing the airflow volume of the first sub-air duct 46 and the second sub-air duct 48.

[0140] Specifically, the outer contour of the cooler 312 is roughly rectangular, and the first clearance portion 66 and the second clearance portion 68 are notches located at the two corners of the rectangle on a diagonal line, thereby creating a misalignment effect.

[0141] In one embodiment, the heat sink 320 is located between the second air inlet 175 and the second air outlet 180, so that when the airflow moves from the second air inlet 175 to the second air outlet 180, it passes through the heat sink 320, thereby exchanging heat with the heat sink 320. The second fan assembly 230 is located between the heat sink 320 and the second air outlet 180. The second air inlet 175 is located on the side of the heat sink 320 away from the second fan assembly 230, which reduces the distance between the second fan assembly 230 and the second air outlet 180, giving the airflow greater force when it is discharged from the second air outlet 180, thereby increasing the air volume.

[0142] Specifically, there are two second air outlets 180, which are spaced apart circumferentially along the housing 100.

[0143] In another embodiment, the heat sink 320 is located between the second air inlet 175 and the second air outlet 180, so that when the airflow moves from the second air inlet 175 to the second air outlet 180, it passes through the heat sink 320, thereby exchanging heat with the heat sink 320. The second fan assembly 230 is located between the second air inlet 175 and the heat sink 320, and the second air outlet 180 is located on the side of the heat sink 320 away from the second fan assembly 230, which reduces the distance between the second fan assembly 230 and the second air inlet 175, so that the second fan assembly 230 can form a greater suction force at the second air inlet 175 when it is working, thereby increasing the air intake volume.

[0144] Preferably, the neck hanger 103 protrudes along the height direction of the housing 100 to form a protrusion 69, and the second fan assembly 230 is installed in the protrusion 69. By making the neck hanger 22 protrude to form the protrusion 69, the overall volume of the neck hanger 103 is increased, thereby increasing the internal space of the neck hanger 103, so that the temperature control assembly 300, the fan assembly 17, and the first sub-air duct 140 and the second sub-air duct 150 can be installed on the neck hanger 103. Moreover, the protrusion 69 protrudes along the height direction of the housing 100, which can avoid increasing the overall thickness of the housing 100.

[0145] Specifically, the protrusion 69 protrudes downward from the middle of the neck hanger 103, the second fan assembly 230 is located on one side of the temperature control assembly 300 along the height direction of the housing 100, and the first blower 50 and the second blower 52 are located on opposite sides of the temperature control assembly 300 along the circumference of the housing 100, that is, the first blower 50, the second blower 52 and the second fan assembly 230 are respectively located on different sides of the temperature control assembly 300.

[0146] In one embodiment, the cooler 312 includes a temperature-conducting plate 71 connected to the cooler 311 and a plurality of temperature-conducting fins 75 located on the side of the temperature-conducting plate 71 away from the cooler 311. Specifically, the temperature-conducting plate 71 is attached and fixed to the side of the cooler 311 near the wearing space 10, and the temperature-conducting fins 75 are located on the side of the temperature-conducting plate 71 near the wearing space 10. The cooling energy generated by the side of the cooler 311 near the wearing space 10 can be transferred to the temperature-conducting plate 71, and then transferred by the temperature-conducting plate 71 to the plurality of temperature-conducting fins 75, so as to increase the contact area between the cooler 312 and the airflow and enhance the heat exchange effect.

[0147] Multiple heat-conducting fins 75 are arranged at intervals to form a cold air flow channel 73 between two adjacent heat-conducting fins 75. The extension direction of the cold air flow channel 73 is the same as the extension direction of the first sub-air channel 140, so that the airflow is smoother when it flows in the cold air flow channel 73, thereby increasing the air volume and reducing noise.

[0148] The heat sink 320 includes a heat sink 77 connected to the cooler 311 and a plurality of heat sink fins 78 located on the side of the heat sink 77 away from the cooler 311. Specifically, the heat sink 77 is attached and fixed to the side of the cooler 311 away from the wearing space 10, and the plurality of heat sink fins 78 are located on the side of the heat sink 77 away from the wearing space 10. The heat generated on the side of the cooler 311 away from the wearing space 10 can be transferred to the heat sink 77, and then transferred by the heat sink 77 to the plurality of heat sink fins 78, so as to increase the contact area between the heat sink 320 and the airflow and enhance the heat exchange effect.

[0149] Multiple heat dissipation fins 78 are arranged at intervals to form a heat dissipation channel 79 between two adjacent heat dissipation fins 78. The extension direction of the heat dissipation channel 79 is the same as the extension direction of the first sub-air duct 140, so that the airflow is smoother when it flows in the heat dissipation channel 79, thereby enhancing the heat dissipation effect of the heat sink 320.

[0150] This utility model discloses a neck-hanging air conditioner, which includes a housing 100. Referring to Figure 1, in some embodiments, the housing 100 includes a neck-hanging part 103 and two handle parts 22 respectively connected to both ends of the neck-hanging part 103. The neck-hanging part 103 and the two handle parts 22 together form a wearing space 10, allowing the housing 100 to be hung around the neck during use. The neck-hanging air conditioner also includes a temperature regulating component 300 and a heat insulation component 30 disposed in the housing 100. Referring to Figure 2, the temperature regulating component 300 and the heat insulation component 30 are disposed, for example, in the neck-hanging part 103. In some embodiments, the temperature regulating component 300 and the heat insulation component 30 may also be disposed on one or both of the two handle parts 22. Alternatively, in some embodiments, a cooling fan is disposed inside the two handle parts 22 to blow airflow for auxiliary cooling.

[0151] Referring to Figures 3 and 4, the temperature control assembly 300 includes a cooler 311, a heat sink 320, and a temperature-conducting shell 14. The cooler 311 has a first temperature-regulating end and a second temperature-regulating end opposite each other along a first direction. The heat sink 320 is disposed on one side of the first temperature-regulating end of the cooler 311 and is thermally connected to the first temperature-regulating end. The temperature-conducting shell 14 is disposed on one side of the second temperature-regulating end of the cooler 311 and is thermally connected to the second temperature-regulating end. The heat sink 320 and the temperature-conducting shell 14 are limited and clamped to the cooler 311 by a heat insulation member 30. The heat insulation member 30 has a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is limited and connected to the temperature-conducting shell 14, and the second connecting portion 32 is limited and connected to the heat sink 320.

[0152] Specifically, the cooler 311 can be a semiconductor cooler. The first temperature-regulating end and the second temperature-regulating end are the cold end and the hot end of the cooler 311, respectively. Taking the main function of a neck air conditioner as cooling as an example, the first temperature-regulating end is the hot end and the second temperature-regulating end is the cold end. Referring to Figure 4, the heat sink 320 is, for example, a finned heat sink, including a heat sink 77 and multiple heat sink fins 78 disposed on the heat sink 77. The heat sink 320 is, for example, made entirely of metal. In some embodiments, a cooling fan is also provided on the housing 100, which can blow airflow onto the heat sink 320. When the cooler 311 is working, the heat generated at the first temperature-regulating end is guided through the heat sink 77 to the heat sink fins 78, and the airflow blown by the cooling fan blows the heat out through the gaps between the heat sink fins 78. The temperature-conducting shell 14 then conducts the cold energy generated by the cooler to the user's skin at the second temperature-regulating end to achieve cooling. The temperature-conducting shell 14 is, for example, a thin metal sheet with good thermal conductivity, such as aluminum or aluminum alloy. Thermal conduction connection refers to connecting two objects together through thermal conduction. The heat sink 320 and the thermally conductive shell 14 can be directly connected to the cooler 311, or they can be connected to the cooler 311 through other thermally conductive media.

[0153] The heat insulation component 30 is made of a plastic material with good heat insulation properties, such as ABS plastic or PP plastic. The first connecting part 31 and the second connecting part 32 are located in two different areas on the heat insulation component 30, respectively connecting the heat sink 320 and the temperature conducting shell 14, thus separating the heat sink 320 and the temperature conducting shell 14 and preventing them from conducting heat to each other. This avoids the heat sink 320 conducting heat to the temperature conducting shell 14, which would affect the cooling effect. Furthermore, the heat sink 320 and the temperature conducting shell 14 are clamped to the cooler 311 by the heat insulation component 30, ensuring that both the heat sink 320 and the temperature conducting shell 14 maintain a tight connection with the cooler 311, preventing the heat sink 320 and the temperature conducting shell 14 from moving away from the temperature conducting shell 14, ensuring good heat conduction connection, and ensuring the efficiency of heat and cold removal.

[0154] In some embodiments, referring to FIG3, the neck-mounted air conditioner further includes a fastener 40, which connects the first connecting portion 31 and the temperature-conducting shell 14 respectively. Specifically, referring to FIG6, the first connecting portion 31 is provided with a through hole 314, one end of the fastener 40 passes through the through hole 314 and connects to the temperature-conducting shell 14, and the other end is limited to the side of the first connecting portion 31 away from the temperature-conducting shell 14. The fastener 40 is, for example, a screw, and the temperature-conducting shell 14 is, for example, provided with a first stud 232, which has an internal thread, so that the fastener 40 can be fastened to the first stud 232 and the heat insulation element 30 is fixed to the temperature-conducting shell 14. The method of fixing with fastener 40 can be adapted to the existing structure and assembly method of the temperature-conducting shell 14.

[0155] In some embodiments, referring to FIG4, the first connecting portion 31 is located on the side of the heat sink 320 away from the cooler 311, and the second connecting portion 32 extends from the first connecting portion 31 towards the heat sink 320 and presses against the heat sink 320. For example, a blank edge is reserved on the heat sink plate 77 of the heat sink 320 as a pressing portion without heat sink fins, so that the second connecting portion 32 can be pressed against the pressing portion to prevent the heat sink 320 from moving away from the cooler 311. The second connecting portion 32 limits the heat sink 320 by pressing, eliminating the need for additional screws and making production and assembly more convenient. Of course, in some embodiments, screws can also be used to fix the heat sink 320 through the second connecting portion 32, as long as the screws and fasteners 40 are spaced apart.

[0156] In some embodiments, the housing 100 (neckband 103) includes a first housing 114 and a second housing 115 facing each other in a first direction. The first housing 114 and the second housing 115 together enclose a mounting cavity 116. Alternatively, the mounting cavity 116 can be formed on one side of the first housing 114. The heat sink 320 and the cooler 311 are disposed within the mounting cavity 116. The first housing 114 is provided with a fifth opening 1111. A temperature-conducting shell 14 is disposed outside the mounting cavity 116 and partially exposed within the fifth opening 1111. The temperature-conducting shell 14 is thermally connected to the second temperature-regulating end of the cooler 311 through the fifth opening 1111. The aforementioned cooling fan is also disposed within the mounting cavity 116, for example. The first housing 114 is the housing on the neckband 103 facing the wearing space 10, while the second housing 115 faces away from the wearing space 10. The second housing 115 is also provided with an air inlet and an air outlet, for example, to allow the cooling fan to draw in airflow and to discharge the cooling airflow from the mounting cavity 116. In some embodiments, a limiting post 1113 is provided on the first housing 114 (see Figure 6). The limiting post 1113 is a hollow post. The first stud 232 on the temperature-conducting shell 14 can be inserted into the limiting post 1113 so that the temperature-conducting shell 14 can be fixed from the inside of the mounting cavity 116 by fastener 40. The limiting post 1113 can play a guiding and limiting role in the assembly process of the temperature-conducting shell 14.

[0157] In some embodiments, the cooler 311 is disposed within the fifth opening 1111, which allows the space for the cooler 311 to be utilized by the thickness of the first housing 114, thereby reducing the overall thickness of the neckpiece 103.

[0158] In some embodiments, referring to FIG4, a contact portion 231 is provided on the side of the temperature-conducting shell 14 facing the first shell 114. The contact portion 231 protrudes towards the cooler 311, and the temperature-conducting shell 14 is thermally connected to the second temperature-regulating end through the contact portion 231. Since the side of the temperature-conducting shell 14 facing the wearing space 10 needs to contact the neck skin, the overall shape of the temperature-conducting shell 14 usually needs to be adapted to the curve of the neck and made into a curved structure. By providing a protruding contact portion 231 on the side facing the first shell 114, a plane can be formed on the contact portion 231, which can make better contact between the temperature-conducting shell 14 and the plane of the cooler 311, ensuring better temperature conduction effect.

[0159] In some embodiments, the fifth opening 1111 is located in the middle of the first housing 114, and the contact portion 231 is located in the middle of the heat-conducting housing 14, which can conduct heat from the middle to the periphery evenly, resulting in a more uniform cooling effect.

[0160] In some embodiments, a blocking member 1112 is further provided on the housing 100, and the blocking member 1112 is adjacent to the heat insulation member 30. The blocking member 1112 is connected to the first housing 114, for example, and can be in the form of a sheet, block, or column. If the fastener 40 becomes slightly loose during use, causing the heat insulation member 30 to rotate, the blocking member 1112 next to the heat insulation member 30 can prevent the heat insulation member 30 from rotating and affecting the fixing effect.

[0161] In some embodiments, the heat insulation member 30 is provided with blocking members 1112 on both opposite sides to prevent rotation in multiple directions. Alternatively, in some embodiments, referring to Figures 5 to 7, one of the blocking member 1112 and the heat insulation member 30 is provided with a slot 33, and the other of the blocking member 1112 and the heat insulation member 30 is provided with a snap-fit ​​member, which snaps into the slot 33. In this case, only one blocking member 1112 is provided for each heat insulation member 30 to prevent rotation of the heat insulation member 30 in multiple directions. Of course, multiple blocking members 1112 can also be provided. Referring to Figures 6 and 7, Figure 6 shows the state where the heat insulation member 30 and the blocking member 1112 are separated, and Figure 7 shows the state where the heat insulation member 30 and the blocking member 1112 are snapped together. Specifically, in Figure 6, the heat insulation member 30 is provided with a slot 33, and the blocking member 1112 is a sheet-like snap-fit ​​member. After assembly, the blocking member 1112 snaps into the slot 33 to prevent the heat insulation member 30 from rotating. In some embodiments, the blocking member 1112 can be correspondingly disposed on the limiting post 1113, for example, it can be integrally formed with the limiting post 1113, which facilitates manufacturing and assembly.

[0162] In some embodiments, as shown in FIG4, heat insulation members 30 are provided on both opposite sides of the heat sink 320 along a second direction, which is perpendicular to the first direction. Providing heat insulation members 30 on opposite sides of the heat sink 320 ensures better fixation and more uniform stress distribution. One or more heat insulation members 30 can be provided on each side of the heat sink 320. Different heat insulation members 30 can be symmetrically or asymmetrically arranged; this embodiment is not limited by this. The structures of different heat insulation members 30 can be the same or different. For example, one heat insulation member 30 can use screws or similar means to fix the heat sink 320 and the temperature-conducting shell 14 at both its first connecting portion 31 and second connecting portion 32, while another heat insulation member 30 uses screws to fix the temperature-conducting shell 14 at its first connecting portion 31 and a press-fit method to fix the heat sink 320 at its second connecting portion 32.
