DETAILED DESCRIPTION
[0034] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0036] It should also be noted that when an element is referred to as being “fixed on” or “disposed on” another element, the element may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.
[0037] See also Figures 1 to 9 An embodiment of the present invention provides a neck hanging fan 10, which is used to be worn around the neck of a user to blow air toward the neck or head of the user to create a cooling effect for the user.
[0038] The neck-hanging fan 10 includes a wearing bracket 12, a temperature control component 14 and a fan component 16. The wearing bracket 12 forms a wearing space 18. The neck-hanging fan 10 can be worn on the neck through the wearing space 18. The temperature control component 14 and the fan component 16 are respectively arranged inside the wearing bracket 12. The temperature control component 14 can cool, and the fan component 16 drives the outside air into the wearing bracket 12 and flows through the temperature control component 14. After the temperature control component 14 cools the passing air, the fan component 16 drives the airflow to blow toward the user, forming the effect of blowing cold air, reducing the influence of the external ambient temperature on the cooling effect of the neck-hanging fan 10, and improving the cooling effect of the neck-hanging fan 10.
[0039] The wearing bracket 12 is preferably made of a material with a certain degree of flexibility, such as silicone, to ensure wearing comfort. At the same time, the wearing bracket 12 can produce a certain degree of deformation to adjust the size of the wearing space 18, so that the neck-hanging fan 10 can better adapt to different users.
[0040] The wearing bracket 12 includes a neck hanging portion 20 and handle portions 22 connected to both ends of the neck hanging portion 20. The two handle portions 22 and the neck hanging portion 20 together enclose a wearing space 18. The temperature control component 14 is located in the neck hanging portion 20, and the fan component 16 is located in the neck hanging portion 20 and / or the handle portions 22. During use, the user can grasp the handle portions 22 with both hands and then wear the neck hanging fan 10 around the neck. After the neck hanging fan 10 is worn around the neck, the neck hanging portion 20 is located on the back of the neck, and the two handle portions 22 are located on opposite sides of the neck.
[0041] It is understandable that the neck portion 20 and the two handle portions 22 can be integrally formed or assembled separately.
[0042] The temperature control assembly 14 includes a refrigeration element 24 and a heat conducting element 26 and a heat dissipating element 28 respectively connected to the opposite sides of the refrigeration element 24. Specifically, the heat conducting element 26 is located on the side of the refrigeration element 24 close to the wearing space 18, and the heat dissipating element 28 is located on the side of the refrigeration element 24 away from the wearing space 18. When the refrigeration element 24 is working, the side close to the wearing space 18 serves as a cooling end and generates cold energy, and the side away from the wearing space 18 serves as a heat generating end and generates heat. The cold energy generated by the refrigeration element 24 can be transferred to the heat conducting element 26 to reduce the temperature of the heat conducting element 26, and the generated heat is transferred to the heat dissipating element 28 to reduce the overall temperature of the refrigeration element 24, while the overall temperature of the heat dissipating element 28 increases. The contact area between the heat dissipating element 28 and the air is large, and the heat dissipation effect is better. The refrigeration element 24 uses the heat dissipating element 28 to assist in heat dissipation, and promptly transfers the heat generated on the side of the refrigeration element 24 away from the wearing space 18 to ensure the heat dissipation effect of the refrigeration element 24.
[0043] In the present application, the cooling element 24 is a semiconductor cooling sheet, which is in sheet shape as a whole. The heat conducting element 26 and the heat dissipating element 28 are respectively attached and fixed to opposite sides of the semiconductor cooling sheet.
[0044] The wearing bracket 12 is provided with a blowing duct 30, a blowing duct inlet 32 and a blowing duct outlet 34 connected to the blowing duct 30, a heat dissipation duct 36, and a heat dissipation duct inlet 38 and a heat dissipation duct outlet 40 connected to the heat dissipation duct 36. The temperature conducting component 26 is located in the blowing duct 30, the heat dissipation component 28 is located in the heat dissipation duct 36, and the fan assembly 16 includes a blowing fan located in the blowing duct 30 and a heat dissipation fan 42 located in the heat dissipation duct 36. When the hair dryer is working, it can draw the outside air into the hair dryer duct 30 through the hair dryer duct inlet 32, and drive the air flow in the hair dryer duct 30 to flow in the direction of the hair dryer duct outlet 34. During the flow in the hair dryer duct 30, the air flow will pass through the temperature conducting member 26 and exchange heat with the temperature conducting member 26. Since the temperature of the temperature conducting member 26 is relatively low, the temperature of the air flow will decrease after the heat exchange with the temperature conducting member 26. The cooled air flow will then be blown toward the user from the hair dryer duct outlet 34 to form the effect of blowing cold air, thereby reducing the influence of the external ambient temperature on the cooling effect of the neck hanging fan 10 and improving the cooling effect of the neck hanging fan 10 on the user. When the heat dissipation fan 42 is working, it can draw the outside air through the heat dissipation member 26 The hot air duct inlet 38 draws air into the heat dissipation duct 36 and drives the air flow in the heat dissipation duct 36 toward the heat dissipation duct outlet 40. The air flow passes through the heat dissipation element 28 and exchanges heat with the heat dissipation element 28 during the flow in the heat dissipation duct 36. Since the temperature of the heat dissipation element 28 is relatively high, the air flow can take away the heat on the heat dissipation element 28 when passing through the heat dissipation element 28, and then be discharged from the heat dissipation duct outlet 40. After the heat on the heat dissipation element 28 is taken away by the air flow, the temperature is reduced, so that the heat generated on the side of the cooling element 24 away from the wearing space 18 can be quickly transferred to the heat dissipation element 28, ensuring the cooling effect of the cooling element 24, so as to ensure the effect of the temperature conducting element 26 in cooling the passing air flow.
[0045] The specific positions of the blowing duct inlet 32 and the blowing duct outlet 34 are not limited, and the two can be located on the same side of the wearing bracket 12, or on different sides of the wearing bracket 12. For example, the blowing duct inlet 32 can be set on the side of the wearing bracket 12 close to or away from the wearing space 18, or on the side of the wearing bracket 12 in its height direction. The blowing duct outlet 34 can be set on the side of the wearing bracket 12 close to the wearing bracket 12, or on the side of the wearing bracket 12 in its height direction, as long as it can blow towards the user.
[0046] In this application, the height direction of the wearing bracket 12 refers to the height direction when the wearing bracket 12 is worn on the human body. Specifically, the wearing bracket 12 is an open ring structure, and the height direction of the wearing bracket 12 is also the axial direction of the wearing space 18.
[0047] Preferably, the heat dissipation duct inlet 38 and the heat dissipation duct outlet 40 are both arranged on the side of the wearing bracket 12 away from the wearing space 18 to prevent the hot air after heat exchange with the heat dissipation element 28 from blowing towards the user.
[0048] The blowing duct 30 and the heat dissipation duct 36 are respectively located on opposite sides of the refrigeration component 24 at the temperature control component 14, that is, the blowing duct 30 is located on the side of the refrigeration component 24 close to the wearing space 18 in the area of the temperature control component 14, and the heat dissipation duct 36 is located on the side of the refrigeration component 24 away from the wearing space 18 in the area of the temperature control component 14. The blowing duct 30 and the heat dissipation duct 36 are separated by the refrigeration component 24 at the temperature control component 14, reducing the risk of mutual interference between the cold air in the blowing duct 30 and the hot air in the heat dissipation duct 36, thereby reducing the influence of the hot air in the heat dissipation duct 36 on the cold air cooling the user.
[0049] Specifically, a mounting bracket 44 is provided inside the neck halter 20. The mounting bracket 44 is annular, and the cooling element 24 is fixedly mounted on the inner side of the mounting bracket 44, thereby indirectly fixing it to the wearing bracket 12. The mounting bracket 44 surrounds the outer periphery of the cooling element 24, and can also, to a certain extent, separate the heat dissipation duct 36 from the blowing duct 30, further reducing the risk of interference between cold air and hot air.
[0050] In one embodiment, the blowing duct 30 includes a first duct 46 and a second duct 48. The blowing fans include a first blowing fan 50 located in the first duct 46 and a second blowing fan 52 located in the second duct 48. The thermal conductive member 26 is partially located in the first duct 46 and partially located in the second duct 48. The first blowing fan 50 can drive airflow in the first duct 46, and the second blowing fan 52 can drive airflow in the second duct 48. This helps increase the airflow inlet and outlet of the neck-hanging fan 10. In addition, the airflow can pass through the thermal conductive member 26 to reduce the temperature when flowing in the first duct 46 and the second duct 48.
[0051] It can be understood that the first air duct 46 and the second air duct 48 may have independent outlets and inlets respectively, or may have the same outlet or inlet.
[0052] In this embodiment, the blowing duct inlet 32 includes a first inlet 54 and a second inlet 56, and the blowing duct outlet 34 includes a first outlet 58 and a second outlet 60. The first inlet 54 and the first outlet 58 are respectively connected to the two ends of the first air duct 46, and the second inlet 56 and the second outlet 60 are respectively connected to the two ends of the second air duct 48. The first blowing fan 50 is located between the first inlet 54 and the first outlet 58, and the second blowing fan 52 is located between the second inlet 56 and the second outlet 60. When the first blowing fan 50 is working, the outside air enters the first air duct 46 through the first inlet 54 and flows in the first air duct 46 toward the first outlet 58. During the flow, the outside air will pass through the part of the heat conducting component 26 located in the first air duct 46, and be discharged from the first outlet 58 and blown toward the user after the temperature is reduced. When the second blowing fan 52 is working, the outside air enters the second air duct 48 through the second inlet 56 and flows in the second air duct 48 toward the second outlet 60. During the flow, the outside air will pass through the part of the heat conducting component 26 located in the second air duct 48, and be discharged from the second outlet 60 and blown toward the user, so that the neck hanging fan 10 can take in air from different inlets and blow cold air to the user from different outlets, thereby increasing the air intake of the neck hanging fan 10 and at the same time increasing the coverage area of the cold air on the human body, that is, increasing the contact area between the cold air and the human body, thereby enhancing the cooling effect of the neck hanging fan 10.
[0053] The first blowing fan 50 and the second blowing fan 52 are respectively located on opposite sides of the heat conducting member 26, that is, the heat conducting member 26 is located between the first blowing fan 50 and the second blowing fan 52. The direction in which the airflow driven by the first blowing fan 50 passes through the heat conducting member 26 is opposite to the direction in which the airflow driven by the second blowing fan 52 passes through the heat conducting member 26. By installing the first blowing fan 50 and the second blowing fan 52 on opposite sides of the heat conducting member 26 and driving the air through the heat conducting member 26 in opposite directions by the first blowing fan 50 and the second blowing fan 52, while ensuring that the airflow driven by the first blowing fan 50 and the second blowing fan 52 can both pass through the heat conducting member 26, the layout of the first blowing fan 50 and the second blowing fan 52 is made more reasonable, thereby improving the compactness of the internal structure of the neck halter fan 10 and preventing the problem of excessive size of a local portion of the neck halter 20 caused by arranging the first blowing fan 50 and the second blowing fan 52 on the same side of the heat conducting member 26.
[0054] Specifically, the first inlet 54 and the second inlet 56, as well as the first outlet 58 and the second outlet 60 are respectively located on opposite sides of the thermal conductor 26, the inlets of the first air duct 46 and the second air duct 48 are respectively located on opposite sides of the thermal conductor 26, and the outlets of the first air duct 46 and the second air duct 48 are also respectively located on opposite sides of the thermal conductor 26, thereby increasing the distance between the first inlet 54 and the second inlet 56 and the first outlet 58 and the second outlet 60, thereby preventing the distance between the two inlets from being too small, causing the air to interfere with each other when passing through and affecting the air intake volume, and also preventing the distance between the two outlets from being too small, causing the cold air coverage area to overlap and affecting the cooling effect.
[0055] Preferably, the heat conducting member 26 is located between the first blowing fan 50 and the second blowing fan 52, and the heat conducting member 26 is located in the middle of the neck hanging portion 20, and the first blowing fan 50 and the second blowing fan 52 are respectively arranged at the two ends of the neck hanging portion 20 close to the handle portion 22, so as to avoid the first blowing fan 50, the second blowing fan 52 and the heat conducting member 26 being too concentrated in the neck hanging portion 20, which is convenient for disassembly and assembly operations, and can also facilitate the design to form the first air duct 46 and the second air duct 48.
[0056] The first air duct 46 and the second air duct 48 are staggered at the temperature conducting member 26 along the height direction of the wearing bracket 12. Since the direction of airflow through the temperature conducting member 26 in the first air duct 46 is opposite to the direction of airflow through the temperature conducting member 26 in the second air duct 48, the first air duct 46 and the second air duct 48 are staggered at the height direction of the wearing bracket 12. This can reduce the impact of airflow in the first air duct 46 and airflow in the second air duct 48 at the temperature conducting member 26, thereby reducing the air output of the neck hanging fan 10.
[0057] In one embodiment, the first inlet 54 and the second inlet 56 are respectively arranged on the side of the neck hanging portion 20 close to the wearing space 18, the first inlet 54 is located on the side of the temperature conducting member 26 away from the first blowing fan 50, and the second inlet 56 is located on the side of the temperature conducting member 26 away from the second blowing fan 52, that is, the first blowing fan 50, the second inlet 56, the temperature conducting member 26, the first inlet 54 and the second blowing fan 52 are arranged at intervals along the circumference of the wearing bracket 12, the second inlet 56 is located between the first blowing fan 50 and the temperature conducting member 26, and the first inlet 54 is located between the second blowing fan 52 and the temperature conducting member 26, that is, the first inlet 54 and the second blowing fan 52 are located on the same side of the temperature conducting member 26, and the second inlet 56 and the first blowing fan 50 are located on the same side of the temperature conducting member 26. When the first blowing fan 50 is working, the outside air enters the first air duct 46 through the first inlet 54, moves from one side of the heat conducting member 26 to the other opposite side, and then blows out from the first outlet 58 after passing through the first blowing fan 50. When the second blowing fan 52 is working, the outside air enters the second air duct 48 through the second inlet 56, moves from one side of the heat conducting member 26 to the other opposite side, and then blows out from the second outlet 60 after passing through the second blowing fan 52, so that the airflow driven by the first blowing fan 50 and the second blowing fan 52 can be fully It is in contact with the heat conducting member 26, thereby enhancing the heat exchange effect between the airflow and the heat conducting member 26, and ensuring the cooling effect of the neck hanging fan 10. In addition, the first blowing fan 50 is located on the side of the heat conducting member 26 close to the first outlet 58, and the second blowing fan 52 is located on the side of the heat conducting member 26 close to the second outlet 60, which reduces the distance between the first blowing fan 50 and the first outlet 58 and the second blowing fan 52 and the second outlet 60, so that the cold air has stronger power when blowing out from the first outlet 58 and the second outlet 60, ensuring that the cold air can reach the user after being blown out.
[0058] Preferably, the first inlet 54 and the second inlet 56 are staggered in the height direction of the wearing bracket 12, so that the two air flows entering the first air duct 46 and the second air duct 48 are staggered with each other when entering, which is conducive to reducing the difficulty of setting the first air duct 46 and the second air duct 48.
[0059] Specifically, the first outlet 58 is located on the side of the first blowing fan 50 away from the heat conducting member 26, and the second outlet 60 is located on the side of the second blowing fan 52 away from the heat conducting member 26, and the first outlet 58 and the second outlet 60 are respectively located on one side of the two handle parts 22 in the height direction of the wearing bracket 12.
[0060] In this embodiment, a first air guide portion 62 and a second air guide portion 64 are provided within the collar portion 20. The first air guide portion 62 and the second air guide portion 64 are located on opposite sides of the thermal conductive member 26. The first air guide portion 62 extends from the first inlet 54 toward the thermal conductive member 26, and the second air guide portion 64 extends from the second inlet 56 toward the thermal conductive member 26. After passing through the first inlet 54, the outside air contacts the first air guide portion 62 and, under the guidance of the first air guide portion 62, moves toward the thermal conductive member 26, ultimately moving from one side of the thermal conductive member 26 to the other opposite side. Similarly, after passing through the second inlet 56, the outside air contacts the second air guide portion 64 and, under the guidance of the second air guide portion 64, moves toward the thermal conductive member 26, ultimately moving from one side of the thermal conductive member 26 to the other opposite side. This serves to guide airflow into the first air duct 46 and the second air duct 48, thereby increasing the air intake volume.
[0061] Specifically, one end of the first air guide portion 62 is connected to the neck hanging portion 20 and the connection portion is located on the side of the first inlet 54 away from the thermal conductor 26, and the other end extends obliquely toward the side of the thermal conductor 26, and the first inlet 54 is located between the thermal conductor 26 and the first air guide portion 62; one end of the second air guide portion 64 is connected to the neck hanging portion 20 and the connection portion is located on the side of the second inlet 56 away from the thermal conductor 26, and the other end extends obliquely toward the other opposite side of the thermal conductor 26, and the second inlet 56 is located between the thermal conductor 26 and the second air guide portion 64, and the first guide portion 62 and the second guide portion 64 are staggered in the height direction of the wearing bracket 12.
[0062] A first avoidance portion 66 is provided on one side of the thermal conductive member 26, corresponding to the first air guide portion 62. The first air guide portion 62 is inserted into the first avoidance portion 66. A second avoidance portion 68 is provided on the other, opposite side of the thermal conductive member 26, corresponding to the second air guide portion 64. The second air guide portion 64 is inserted into the second avoidance portion 68. Both the first avoidance portion 66 and the second avoidance portion 68 are notch-shaped and are staggered in the height direction of the wearing bracket 12. After passing through the first inlet 54, outside air enters the notch-shaped first avoidance portion 66 under the guidance of the first air guide portion 62 and then flows along the first air duct 46. Outside air passes through the second inlet 56 and enters the notch-shaped second avoidance portion 68 under the guidance of the second air guide portion 64 and then flows along the second air duct 48. This reduces the diffusion of airflow to the surrounding areas after passing through the first and second inlets 54 and 56, thereby increasing the air volume entering the first and second air ducts 46 and 48.
[0063] Specifically, the outer contour of the heat conducting member 26 is formed to be roughly rectangular, and the first avoidance portion 66 and the second avoidance portion 68 are notches provided at two corners of the rectangle on a diagonal line, thereby forming a staggered effect.
[0064] In another embodiment, the first outlet 58 and the second outlet 60 are respectively arranged on the side of the neck hanging part 20 close to the wearing space 18, the first outlet 58 is located on the side of the temperature conducting member 26 away from the first blowing fan 50, and the second outlet 60 is located on the side of the temperature conducting member 26 away from the second blowing fan 52, that is, the first blowing fan 50, the second outlet 60, the temperature conducting member 26, the first outlet 58 and the second blowing fan 52 are arranged at intervals along the circumference of the wearing bracket 12, the second outlet 60 is located between the first blowing fan 50 and the temperature conducting member 26, and the first outlet 58 is located between the second blowing fan 52 and the temperature conducting member 26, that is, the first outlet 58 and the second blowing fan 52 are located on the same side of the temperature conducting member 26, and the second outlet 60 and the first blowing fan 50 are located on the same side of the temperature conducting member 26. When the first blowing fan 50 and the second blowing fan 52 are working, they can both move the airflow from one side of the heat conducting member 26 to the other side, so that the airflow can fully contact the heat conducting member 26 to enhance the heat exchange effect between the airflow and the heat conducting member 26. Moreover, the first blowing fan 50 is located on the side of the heat conducting member 26 away from the first outlet 58, and the second blowing fan 52 is located on the side of the heat conducting member 26 away from the second outlet 60, which reduces the distance between the first blowing fan 50 and the first inlet 54 and the second blowing fan 52 and the second inlet 56, so that the first blowing fan 50 and the second blowing fan 52 can form a greater suction force at the first inlet 54 and the second inlet 56 to increase the air intake.
[0065] Preferably, the first outlet 58 and the second outlet 60 are staggered in the height direction of the wearing bracket 12, so that the airflows blown out from the first outlet 58 and the second outlet 60 are staggered in the height direction to contact the user's skin at different heights, so as to increase the coverage area of the cold air on the human body.
[0066] Specifically, the first inlet 54 and the second inlet 56 are both located on the side of the neck hanging portion 20 away from the wearing space 18, and the first inlet 54 and the second inlet 56 are arranged at intervals along the circumference of the wearing bracket 12. The first inlet 54 is close to the first blowing fan 50, and the second outlet 60 is close to the second blowing fan 52.
[0067] In this embodiment, a first air guide portion 62 and a second air guide portion 64 are provided within the neck portion 20. The first air guide portion 62 and the second air guide portion 64 are located on opposite sides of the heat conducting member 26. The first air guide portion 62 extends from the first outlet 58 toward the heat conducting member 26, and the second air guide portion 64 extends from the second outlet 60 toward the heat conducting member 26. When the airflow within the first air duct 46 moves from the side of the heat conducting member 26 away from the first outlet 58 to the first air guide portion 62, the first air guide portion 62 can guide the airflow toward the first outlet 58. When the airflow within the second air duct 48 moves from the side of the heat conducting member 26 away from the second outlet 60 to the second air guide portion 64, the second air guide portion 64 can guide the airflow toward the second outlet 60, thereby guiding the airflow to be blown outward from the first outlet 58 and the second outlet 60 to increase the airflow volume.
[0068] Specifically, one end of the first air guide portion 62 is connected to the neck hanging portion 20 and the connection portion is located on the side of the first outlet 58 away from the thermal conductor 26, and the other end extends obliquely toward the side of the thermal conductor 26, and the first outlet 58 is located between the thermal conductor 26 and the first air guide portion 62; one end of the second air guide portion 64 is connected to the neck hanging portion 20 and the connection portion is located on the side of the second outlet 60 away from the thermal conductor 26, and the other end extends obliquely toward the other opposite side of the thermal conductor 26, and the second outlet 60 is located between the second air guide portion 64 and the thermal conductor 26, and the first guide portion 62 and the second guide portion 64 are staggered in the height direction of the wearing bracket 12.
[0069] A first avoidance portion 66 is provided on one side of the heat conducting member 26, corresponding to the first air guide portion 62. The first air guide portion 62 is inserted into the first avoidance portion 66. A second avoidance portion 68 is provided on the other opposite side of the heat conducting member 26, corresponding to the second air guide portion 64. The second air guide portion 64 is inserted into the second avoidance portion 68. The first avoidance portion 66 and the second avoidance portion 68 are both notch-shaped, and the first avoidance portion 66 and the second avoidance portion 68 are staggered in the height direction of the wearing bracket 12. The airflow in the first air duct 46, guided by the first air guide portion 62, first enters the notch-shaped first avoidance portion 66 before being blown out from the first outlet 58. The airflow in the second air duct 48, guided by the second air guide portion 64, first enters the notch-shaped second avoidance portion 68 before being blown out from the second outlet 60. This reduces the diffusion of the airflow from the first outlet 58 and the second outlet 60, thereby increasing the airflow volume of the first air duct 46 and the second air duct 48.
[0070] Specifically, the outer contour of the heat conducting member 26 is formed to be roughly rectangular, and the first avoidance portion 66 and the second avoidance portion 68 are notches provided at two corners of the rectangle on a diagonal line, thereby forming a staggered effect.
[0071] In one embodiment, the heat sink 28 is located between the heat dissipation duct inlet 38 and the heat dissipation duct outlet 40, so that the airflow passing through the heat sink 28 as it moves from the heat dissipation duct inlet 38 toward the heat dissipation duct outlet 40 will exchange heat with the heat sink 28. The heat dissipation fan 42 is located between the heat sink 28 and the heat dissipation duct outlet 40. The heat dissipation duct inlet 38 is located on the side of the heat sink 28 away from the heat dissipation fan 42. This reduces the distance between the heat dissipation fan 42 and the heat dissipation duct outlet 40, allowing the airflow to be discharged from the heat dissipation duct outlet 40 with greater power, thereby increasing the airflow volume.
[0072] Specifically, there are two heat dissipation air duct outlets 40 , and the two heat dissipation air duct outlets 40 are arranged at intervals along the circumference of the wearing bracket 12 .
[0073] In another embodiment, the heat sink 28 is located between the heat duct inlet 38 and the heat duct outlet 40, so that the airflow passing through the heat sink 28 as it moves from the heat duct inlet 38 toward the heat duct outlet 40 will exchange heat with the heat sink 28. The heat sink fan 42 is located between the heat duct inlet 38 and the heat sink 28, and the heat duct outlet 40 is located on the side of the heat sink 28 away from the heat sink fan 42. This reduces the distance between the heat sink fan 42 and the heat duct inlet 38, allowing the heat sink fan 42 to generate greater suction at the heat duct inlet 38 when in operation, thereby increasing the amount of air entering.
[0074] Preferably, the neck hanging portion 20 protrudes along the height direction of the wearing bracket 12 to form a mounting portion 69, and the heat dissipation fan 42 is installed in the mounting portion 69. By making the neck hanging portion 22 protrude to form the mounting portion 69, the overall volume of the neck hanging portion 20 is increased, thereby increasing the internal space of the neck hanging portion 20, so that the temperature control component 14, the fan component 16, the blowing air duct 30, the heat dissipation air duct 36, etc. can be arranged on the neck hanging portion 20. In addition, the mounting portion 69 protrudes along the height direction of the wearing bracket 12 to avoid increasing the overall thickness of the wearing bracket 12.
[0075] Specifically, the mounting portion 69 protrudes downward from the middle of the neck hanging portion 20, the heat dissipation fan 42 is located on one side of the temperature adjustment component 14 along the height direction of the wearing bracket 12, and the first blowing fan 50 and the second blowing fan 52 are located on opposite sides of the temperature adjustment component 14 along the circumference of the wearing bracket 12, that is, the first blowing fan 50, the second blowing fan 52 and the heat dissipation fan 42 are respectively located on different sides of the temperature adjustment component 14.

Specifically, the thermal conductive plate 70 is fixed to the side of the refrigeration element 24 close to the wearing space 18, and the thermal conductive fins 72 are located on the side of the thermal conductive plate 70 close to the wearing space 18. The cold energy generated by the refrigeration element 24 on the side close to the wearing space 18 can be transferred to the thermal conductive plate 70, and then transferred to the plurality of thermal conductive fins 72 by the thermal conductive plate 70, so as to increase the contact area between the thermal conductive element 26 and the airflow and enhance the heat exchange effect.
[0077] Multiple thermal conductive fins 72 are arranged at intervals to form a cold air flow channel 73 between two adjacent thermal conductive fins 72. The extension direction of the cold air flow channel 73 is the same as the extension direction of the blowing air duct 30, so that the air flow in the cold air flow channel 73 is smoother, thereby increasing the air output and reducing noise.
[0078] The heat sink 28 includes a heat sink 74 connected to the refrigeration element 24 and a plurality of heat sink fins 76 located on the side of the heat sink 74 away from the refrigeration element 24. Specifically, the heat sink 74 is fixed to the side of the refrigeration element 24 away from the wearing space 18, and the plurality of heat sink fins 76 are located on the side of the heat sink 74 away from the wearing space 18. The heat generated on the side of the refrigeration element 24 away from the wearing space 18 can be transferred to the heat sink 74, and then transferred from the heat sink 74 to the plurality of heat sink fins 76, so as to increase the contact area between the heat sink 28 and the airflow and enhance the heat exchange effect.
[0079] Multiple heat dissipation fins 76 are arranged at intervals to form a heat dissipation channel 78 between two adjacent heat dissipation fins 76. The extension direction of the heat dissipation channel 78 is the same as the extension direction of the blowing duct 30, so that the air flow flows more smoothly in the heat dissipation channel 78, thereby enhancing the heat dissipation effect of the heat dissipation element 28.
