This allows a portion of the airflow from the air outlet of the fan casing to be blown through the first air guide channel to the corresponding area of ​​the temperature-conducting component, and through the second air guide channel to another area of ​​the corresponding temperature-conducting component, thereby allowing a portion of the airflow from the air outlet of the fan casing to be blown through the first air guide channel to the corresponding area of ​​the temperature-conducting component, and through the second air guide channel to the corresponding area of ​​the temperature-conducting component. The airflow from the vent can be evenly distributed across all areas of the temperature guide, ensuring that the airflow passes through all areas of the temperature guide and that each area of ​​the temperature guide can transfer heat to the airflow. This not only makes the heat transfer efficiency of the temperature guide high, but also makes the cooling or heating of the airflow passing through the temperature guide more uniform.

[0061] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0062] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0063] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0064] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0065] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0066] like Figure 1As shown, the outer casing of the fan 01 may include a volute 011 and a volute tongue 012. The impeller 013 of the fan 01 is located inside the volute 011. The volute 011 is typically composed of a volute plate and two side plates joined together. The volute plate usually extends in a spiral shape. The volute 011 is mainly used to collect the airflow from the impeller 013 and guide it to the outlet of the volute 011. The volute tongue 012 is located at the outlet of the volute 011 and has a tongue-shaped structure. When the airflow flowing out of the volute 011 passes near the volute tongue 012, the volute tongue 012 splits it in two: most of the airflow flows to the outlet of the fan 01, while a small portion of the airflow flows back to the volute 011 through the gap between the volute tongue 012 and the impeller 013. After rotating once inside the volute 011 with the impeller 013, the airflow returns to the volute tongue 012 to participate in a new split.

[0067] In neck-mounted air conditioners, a fan blows air through a temperature-conducting element. After passing through this element, the air is either cooled or heated, delivering cool or warm air to the user to achieve the purpose of heat dissipation or warmth. In related technologies, the fan outlet typically faces the temperature-conducting element. The airflow from the volute casing preferentially exits from the side of the volute casing's outlet that it first passes through, flowing towards the corresponding part of the temperature-conducting element. This results in less airflow flowing towards the part of the temperature-conducting element closer to the volute tongue, causing uneven heat transfer from different parts of the element into the airflow. Consequently, the neck-mounted air conditioner has lower efficiency, resulting in poor heat dissipation or warmth retention.

[0068] In view of this, the present invention provides a neck-mounted air conditioner that enables the fan to blow air more evenly towards the temperature guide element, thereby enabling the heat transferred to the air by each part of the temperature guide element to be more even, providing users with more comfortable cool or hot air, and having a better heat dissipation or heat preservation effect.

[0069] The technical solution of this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0070] This application provides a neck-mounted air conditioner, such as... Figures 2-5As shown, the neck-mounted air conditioner 10 includes a wearing bracket, an air duct 2, a cooling component 3, a temperature guiding component 4, a first fan 5, and an air guide component 6. The wearing bracket includes a housing 11, which has a first air inlet 1a and a first air outlet 1b. The air duct 2, cooling component 3, temperature guiding component 4, first fan 5, and air guide component 6 are all disposed inside the housing 11. The air outlet side of the air duct 2 corresponds to the first air outlet 1b; the temperature-conducting component 4 is disposed inside the air duct 2 and is thermally connected to the cooling component 3; the first fan 5 includes a fan housing and an impeller 53 disposed inside the fan housing, the air inlet of the fan housing corresponds to the first air inlet 1a, the air outlet of the fan housing is connected to the air inlet side of the air duct 2 and corresponds to the temperature-conducting component 4, the fan housing includes a volute 51 and a volute tongue 52, the volute 51 includes a spiral section 511 and an extension section 512, the spiral section 511 is arranged around the impeller 53, one end of the spiral section 511 is connected to the extension section 512, and the other end of the spiral section 511 is connected to the volute tongue 52, the volute tongue 52 and the extension section 512 are along a first direction (e.g. Figure 5 The air outlet of the fan housing is formed between the extension section 512 and the volute tongue 52, with the extension section 512 and the volute tongue 52 respectively positioned relative to each other in the direction of x. The first end 6a of the air guide 6 is located between the extension section 512 and the impeller 53, and the second end 6b of the air guide 6 extends toward the air outlet of the fan housing. The first air guide channel 5a is formed between the air guide 6 and the extension section 512, and the second air guide channel 5b is formed between the air guide 6 and the volute tongue 52. The first air guide channel 5a and the second air guide channel 5b correspond to different areas of the heat-conducting component 4 respectively.

[0071] Therefore, the air duct 2, cooling component 3, temperature conductive component 4, first fan 5, and air guide component 6 are all disposed within the housing 11; the air outlet side of the air duct 2 corresponds to the first air outlet 1b; the temperature conductive component 4 is disposed within the air duct 2 and is thermally connected to the cooling component 3; the first fan 5 includes a fan housing and an impeller 53 disposed within the fan housing, the air inlet of the fan housing corresponds to the first air inlet 1a, and the air outlet of the fan housing is connected to the air inlet side of the air duct 2 and corresponds to the temperature conductive component 4; the fan housing includes a volute 51 and a volute tongue 52, the volute 51 includes a spiral section 511 and an extension section 512, the spiral section 511 is arranged around the impeller 53, one end of the spiral section 511 is connected to the extension section 512, and the spiral section... The other end of 511 is connected to the volute tongue 52. The volute tongue 52 and the extension section 512 are arranged opposite to each other along the first direction. The air outlet of the fan housing is formed between the extension section 512 and the volute tongue 52. It can be cooled or heated by the cooling component 3, so that the heat-conducting component 4 connected to it is cooled or heated. The airflow from the impeller 53 is collected by the volute 51 and blown from the air outlet of the fan housing formed between the extension section 512 and the volute tongue 52 toward the cooled or heated heat-conducting component 4. When the airflow flows through the heat-conducting component 4, it can carry away the heat on the heat-conducting component 4, so that the airflow becomes cool or hot. The air delivered through the first air outlet 1b can be cold air or hot air, so as to dissipate heat or keep warm for the user's neck.

[0072] The first end 6a of the air guide 6 is located between the extension section 512 and the impeller 53, and the second end 6b of the air guide 6 extends towards the air outlet of the fan casing. A first air guide channel 5a is formed between the air guide 6 and the extension section 512, and a second air guide channel 5b is formed between the air guide 6 and the volute tongue 52. The first air guide channel 5a and the second air guide channel 5b correspond to different areas of the temperature-conducting component 4, respectively. This allows part of the airflow flowing out of the air outlet of the fan casing to be blown to the corresponding area of ​​the temperature-conducting component 4 through the first air guide channel 5a, and to the other area of ​​the corresponding temperature-conducting component 4 through the second air guide channel 5b, thereby enabling... The airflow from the outlet of the fan casing can be evenly distributed across the temperature guide 4, allowing the airflow to pass through each area of ​​the temperature guide 4. This ensures that each area of ​​the temperature guide 4 can transfer heat to the airflow, resulting in high heat transfer efficiency of the temperature guide 4 and consistent cooling or heating of the airflow. Consequently, the temperature of the cold or hot air delivered from each area of ​​the first air outlet 1b is more uniform, enabling the neck air conditioner 10 to provide users with more comfortable cold or hot air and thus have better heat dissipation or heat preservation effects.

[0073] The cooling element 3 can be disposed inside the air duct 2, outside the air duct 2, or part of the cooling element 3 can be located inside the air duct 2 while the other part is located outside the air duct 2; no limitation is made here. Furthermore, the cooling element 3 can be a thermoelectric cooler (TEC). Thus, when energized, the opposite sides of the cooling element 3 form a hot surface and a cold surface, respectively. By switching the positive and negative terminals of the voltage connected to the cooling element 3, the cooling element 3 can switch between hot and cold surfaces, allowing the temperature-conducting element 4 to cool or heat up. This, in turn, allows the airflow passing through the temperature-conducting element 4 to cool or heat up, so that cold or hot air is delivered from the first air outlet 1b.

[0074] It should be noted that the above-mentioned heat conduction connection refers to the fact that two objects can directly contact each other to form a heat transfer, or indirectly contact each other to form a heat transfer. For example, they can indirectly contact each other through thermal grease, thermal silicone, or graphite as intermediate thermal conductive media to form a heat transfer.

[0075] The first fan 5 mentioned above can be a centrifugal fan, an axial fan, etc., and is not limited here.

[0076] The spiral section 511 of the volute 51 can extend in the form of a logarithmic spiral or an Archimedean spiral, so that the volute 51 can have a better acceleration effect on the airflow gathered from the impeller 53.

[0077] Optionally, such as Figure 5 As shown, the air guide 6 is an arc-shaped plate, and the convex surface of the arc-shaped plate faces the extension. The arc-shaped plate has adjacent straight edges and arc edges, and the straight edges extend along the axial direction of the first fan 5.

[0078] Therefore, the generatrix of the arc-shaped surface of the air guide 6 can extend along the direction from the first fan 5 to the heat-conducting element 4, reducing the obstruction of the airflow by the air guide 6. This allows the airflow to flow more smoothly through the first air guide channel 5a and the second air guide channel 5b, reducing the noise when the airflow flows through the air outlet of the fan casing. In addition, it can effectively reduce the probability of the airflow being obstructed by the air guide 6 and flowing towards the impeller 53, thus improving the efficiency of the first fan 5.

[0079] It should be explained that the generatrix of the arc-shaped surface of the aforementioned air guide 6 refers to a line that forms the arc-shaped surface of the air guide plate along the trajectory of continuous motion in space.

[0080] The air guide 6 has a generatrix on its arc-shaped surface. The bending direction of the generatrix is ​​approximately the same as the rotation direction of the impeller 53. This allows the air guide 6 to separate the airflow along the flow direction of the airflow coming out of the volute 51, making the air guide 6 less obstructive to the airflow. This makes it less likely for the airflow to form vortices at the air guide plate, thus enabling the air guide 6 to better separate the airflow and further reduce the noise when the airflow flows through the air outlet of the fan casing. In addition, it can further reduce the probability of the airflow being obstructed by the air guide 6 and flowing towards the impeller 53, further improving the efficiency of the first fan 5.

[0081] Optionally, such as Figure 5 As shown, the first end 6a of the air guide 6 is pointed.

[0082] This further reduces the obstruction of airflow by the air guide 6, allowing the air guide 6 to better divide the airflow and further reduce the noise of the airflow when it flows through the air outlet of the fan casing.

[0083] The cross-sectional shape of the first end 6a can be any one of the following: arc, triangle, trapezoid, or a combination of trapezoid and arc. It is not limited here, as long as it can reduce the obstruction of airflow by the air guide 6. The specific shape can be selected according to the actual situation.

[0084] In addition, the ratio of the minimum thickness of the first end 6a to the thickness of the air guide 6 is a, where 0 < a ≤ 0.5.

[0085] Therefore, the thickness of the first end 6a can be relatively thin, so that the first end 6a of the air guide 6 has little obstruction to the airflow. At the same time, the first end 6a can gradually thicken along the flow direction of the air guide 6 until it is consistent with the thickness of the plate of the air guide 6, so that the first end 6a can have good strength, so that the first end 6a of the air guide 6 is not prone to breakage when dividing and guiding the airflow with a high speed.

[0086] It is understandable that the ratio of the minimum thickness of the first end 6a to the thickness of the air guide 6 can be infinitely close to 0, that is, the thickness of the first end 6a can be infinitely close to 0. This allows the first end 6a to be relatively sharp, so as to obstruct the airflow less and divert the airflow better.

[0087] When the ratio of the minimum thickness of the first end 6a to the thickness of the air guide 6 is greater than 0.5, although the first end 6a can have better structural strength, it will result in the first end 6a having a greater obstruction effect on airflow, which will easily lead to greater noise generated by the airflow at this point.

[0088] The ratio of the minimum thickness of the first section to the thickness of the air guide 6 can be 0.1, 0.2, 0.35, 0.5, etc., and is not limited here.

[0089] The volute 51 is mainly used to collect the airflow thrown out from the impeller 53 and guide the airflow to the air outlet of the fan housing. When the airflow reaches the air outlet of the fan housing, it will preferentially flow out through the first air guide channel 5a. In order to make the airflow through the first air guide channel 5a and the second air guide channel 5b approximately the same, in some embodiments, the width of the first air guide channel 5a is smaller than the width of the second air guide channel 5b along the first direction.

[0090] Therefore, a large air volume can be avoided from flowing through the first air guide channel 5a to the temperature guide element 4, so that the air volume flowing through the first air guide channel 5a and the second air guide channel 5b can be roughly the same. This makes the air flowing through the first air guide channel 5a and the second air guide channel 5b more uniform, so that the heat transferred to the air in each area of ​​the temperature guide element 4 can be more even, and the cooling or heating of the airflow flowing through the temperature guide element 4 can be roughly the same. This makes the temperature of the cold or hot air delivered from each area of ​​the first air outlet 1b more consistent, and thus the neck air conditioner 10 can provide users with more comfortable cold or hot air.

[0091] In addition, along the air outlet direction of the fan casing, the distance between the air guide 6 and the extension section 512 gradually increases.

[0092] Therefore, when the airflow passes through the first air guide channel 5a, it can gradually diffuse into a larger area of ​​the temperature guide element 4 along the air outlet direction of the fan casing, effectively improving the efficiency of the airflow to each area of ​​the temperature guide element 4. This allows the airflow to pass through the temperature guide element 4 more quickly and exit from the first air outlet 1b, thus enabling the neck air conditioner 10 to quickly dissipate heat or keep warm for the user after it is turned on.

[0093] In other embodiments, such as Figures 2-6 As shown, the first air outlet 1b includes a first sub-air outlet 11b and a second sub-air outlet 12b. The first sub-air outlet 11b is located on the near-surface surface 111 of the housing, and the second sub-air outlet 12b is located on the far-surface surface 112 of the housing. The air duct 2 includes a first air duct 21 and a second air duct 22. The first air duct 21 connects the air outlet of the fan housing to the first sub-air outlet 11b, and the second air duct 22 connects the air outlet of the fan housing to the second sub-air outlet 12b. The cooling component 3 includes a first mounting surface and a second mounting surface. The first mounting surface is one of the cooling surface and the heating surface, and the second mounting surface is the other of the cooling surface and the heating surface. The temperature guiding component 4 includes a first temperature guiding component 41 and a second temperature guiding component 42. The first temperature guiding component 41 is thermally connected to the first mounting surface, and the second temperature guiding component 42 is thermally connected to the second mounting surface. The first temperature guiding component 41 is located inside the first air duct 21, and the second temperature guiding component 42 is located inside the second air duct 22.

[0094] Therefore, the neck air conditioner 10 can provide both cold and hot air to the user, improving its applicability. Specifically, when the air blown from the first fan 5 cools the first temperature-conducting element 41, it can also dissipate heat from the second temperature-conducting element 42, so that the air delivered from the first sub-air outlet 11b is cold air to dissipate heat from the user's neck, and the air delivered from the second sub-air outlet 12b is hot air to dissipate heat from the heating surface of the cooling element 3. When the air blown from the first fan 5 dissipates heat from the first temperature-conducting element 41, it can also cool the second temperature-conducting element 42, so that the air delivered from the first sub-air outlet 11b is hot air to keep the user's neck warm, and the air delivered from the second sub-air outlet 12b is cold air to cool the cooling surface of the cooling element 3.

[0095] It should be explained that the skin-friendly surface 111 of the shell refers to the side of the shell 11 facing the neck when wearing the neck-mounted air conditioner 10. The skin-friendly surface 112 of the shell refers to the side of the shell 11 facing away from the neck when wearing the neck-mounted air conditioner 10.

[0096] The air duct 2 may include a first air duct wall and a second air duct wall arranged opposite to each other, both of which extend in the direction from the first fan 5 to the temperature guide member 4. A fixing frame may be provided inside the air duct 2, which is connected between the first air duct wall and the second air duct wall to divide the air duct 2 into a first air duct 21 and a second air duct 22. The cooling component 3, the first temperature guide member 41, and the second temperature guide member 42 are all fixed on the fixing frame.

[0097] In addition, the first temperature-conducting element 41 may include a body and multiple temperature-conducting fins disposed on the body. The multiple temperature-conducting fins are used to increase the contact area between the first temperature-conducting element 41 and the airflow in the first air duct 21, effectively improving the rate of heating or cooling of the airflow in the first air duct 21. Furthermore, the temperature-conducting fins extend along the flow direction of the airflow in the first air duct 21, so that the temperature-conducting fins also have the function of guiding airflow.

[0098] The implementation of the second temperature-conducting element 42 is roughly the same as that of the first temperature-conducting element 41. For details, please refer to the above description, which will not be repeated here.

[0099] Optionally, such as Figure 7 and Figure 8As shown, a partition 54 is provided inside the volute 51. The partition 54 has a clearance hole 541, and the hole wall of the clearance hole 541 surrounds the impeller 53. The partition 54 extends into the first air guide channel 5a and the second air guide channel 5b. The partition 54 is used to divide the air outlet of the fan housing into a first air outlet 5c and a second air outlet 5d of the fan housing. The first air outlet 5c of the fan housing is connected to the air inlet side of the first air duct 21 and corresponds to the first temperature guide element 41. The second air outlet 5d of the fan housing is connected to the air inlet side of the second air duct 22 and corresponds to the second temperature guide element 42. The impeller 53 includes a first blade assembly 531 stacked along the axial direction of the first fan 5 and The second fan blade assembly 532, the first fan blade assembly 531 is located on one surface of the partition 54 and corresponds to the first air outlet 5c of the fan housing, the second fan blade assembly 532 is located on the other surface of the partition 54 and corresponds to the second air outlet 5d of the fan housing; the air guide 6 includes a first air guide 61 and a second air guide 62, one side of the first air guide 61 is connected to one surface of the partition 54, the other side of the first air guide 61 away from the partition 54 abuts against the housing 11 or has a preset gap, one side of the second air guide 62 is connected to the other surface of the partition 54, the other side of the second air guide 62 away from the partition 54 abuts against the housing 11 or has a preset gap.

[0100] Therefore, the air generated by the first fan blade assembly 531 can flow to the first air outlet 5c of the fan housing, and at the first air outlet 5c of the fan housing, it can be guided to each area of ​​the first temperature-conducting component 41 through the first air guide 61; the air generated by the second fan blade assembly 532 can flow to the second air outlet 5d of the fan housing, and at the second air outlet 5d of the fan housing, it can be guided to each area of ​​the second temperature-conducting component 42 through the second air guide 62. Thus, the air flowing through the first temperature-conducting component 41 and the second temperature-conducting component 42 can have a large air volume, which not only makes the heat conduction efficiency of the first temperature-conducting component 41 and the second temperature-conducting component 42 high, improving the efficiency of the neck air conditioner 10, but also allows more air to be delivered from the first sub-air outlet 11b and the second sub-air outlet 12b, thereby effectively improving the heat dissipation or heat preservation effect of the neck air conditioner 10.

[0101] The partition 54 can be welded to the volute 51, or the partition 54 and the volute 51 can be integrally formed; there is no limitation on this.

[0102] The first blade assembly 531 and the second blade assembly 532 are stacked along the axial direction of the first fan 5, and the first blade assembly 531 and the second blade assembly 532 may share the same rotating shaft, or each may be connected to a rotating shaft. Additionally, the first blade assembly 531 and the second blade assembly 532 may share a hub, or each may be connected to a hub; this is not limited. In some embodiments, the first blade assembly 531 and the second blade assembly 532 may share a rotating shaft and a hub, so that the axial dimension of the first fan 5 is smaller, which is beneficial for the miniaturization of the neck-mounted air conditioner 10.

[0103] Optionally, the cross-sectional area of ​​the second air outlet 5d of the fan housing is larger than the cross-sectional area of ​​the first air outlet 1b of the fan housing.

[0104] Therefore, the air flowing through the second air outlet 5d of the fan housing has a lower speed, so that the air delivered from the second sub-air outlet 12b has less noise; the air flowing through the first air outlet 5c of the fan housing has a higher speed, so that the air delivered from the first sub-air outlet 11b has a higher wind speed, so that when the user wears the neck air conditioner 10, it can better dissipate heat or keep the neck warm, so that the user feels cooler or warmer.

[0105] The extension section 512 includes a first extension section and a second extension section connected to each other. Both the first and second extension sections are connected to one end of the spiral section 511 of the volute 51. The first extension section is located on one surface of the partition 54, and the second extension section is located on the other surface of the partition 54. The volute tongue 52 includes a first volute tongue and a second volute tongue, both connected to the other end of the spiral section 511. Along a first direction, the first volute tongue is positioned opposite to the first extension section 512, and the second volute tongue is positioned opposite to the second extension section. A first air outlet 5c of the fan housing is formed between the first extension section and the first volute tongue, and a second air outlet 5d of the fan housing is formed between the second extension section and the second volute tongue. Therefore, the size of the first air outlet 5c of the fan housing can be adjusted by the distance between the first volute tongue and the first extension section, and the size of the second air outlet 5d of the fan housing can be adjusted by the distance between the second volute tongue and the second extension section. The structure is simple and easy to implement.

[0106] In some embodiments, such as Figure 9 and Figure 10As shown, the housing 11 includes a wearing section 113 and clamping arm sections 114 connected to both ends of the wearing section 113. The first fan 5, the cooling component 3 and the temperature-conducting component 4 are all disposed in the wearing section 113. The wearing section 113 is provided with a first air inlet 1a near both ends. The wearing section 113 is provided with a first fan 5 near both ends. The cooling component 3 and the temperature-conducting component 4 are located between the two first fans 5. The first air outlet 1b is located between the two first air inlets 1a.

[0107] Therefore, the two first fans 5 can blow air through the temperature guide element 4 respectively, so that the air volume flowing through the temperature guide element 4 can be larger, and the air volume flowing out from the first air outlet 1b can be larger, so that when the user wears the neck air conditioner 10, heat dissipation or heat preservation can be carried out more quickly, so that the user can feel cooler or warmer.

[0108] In particular, along the opposite direction of the two clip arm sections 114, the first air outlet 1b can be located in the middle of the wearing strap, so that when the user wears the neck air conditioner 10, the air delivered from the first air outlet 1b can blow towards the middle of the human neck, so that the air can flow along the human neck towards the shoulder, so that the user can feel cooler or warmer.

[0109] In addition, the two clamping arm sections 114 can be symmetrically arranged about the center line of the wearing section 113, and the two first fans 5 can be symmetrically arranged about the center line of the wearing section 113, so that the weight of the neck-hanging air conditioner 10 on both sides symmetrical about the center line of the wearing section 113 can be more consistent, thereby improving the comfort of the user when wearing the neck-hanging air conditioner 10.

[0110] Optionally, such as Figure 9 and Figure 10 As shown, the first air inlet 1a is disposed on the near-skin surface 1131 of the wearing section, and / or, the first air inlet 1a is disposed on the far-skin surface 1132 of the wearing section; the first air outlet 1b is disposed on the near-skin surface 1131 of the wearing section, or, the first air outlet 1b is disposed on both the near-skin surface 1131 and the far-skin surface 1132 of the wearing section.

[0111] Therefore, the first air inlet 1a and the first air outlet 1b can be set as needed, which facilitates the setting of the first air inlet 1a and the first air outlet 1b.

[0112] The first air inlet 1a can be located on the near-skin surface 1131 of the wearing section, or on the far-skin surface 1132 of the wearing section, or both the near-skin surface 1131 and the far-skin surface 1132 of the wearing section can be provided with the first air inlet 1a. No limitation is made here.

[0113] like Figure 10As shown, the first air inlet 1a includes a first sub-air inlet 11a and a second sub-air inlet 12a. The first sub-air inlet 11a is disposed on the near-skin surface 1131 of the wearing section, and the second sub-air inlet 12a is disposed on the far-skin surface 1132 of the wearing section; and / or, the first air outlet 1b includes a first sub-air outlet 11b and a second sub-air outlet 12b. The first sub-air outlet 11b is disposed on the near-skin surface 1131 of the wearing section, and the second sub-air outlet 12b is disposed on the far-skin surface 1132 of the wearing section.

[0114] Therefore, by setting the first sub-air inlet 11a on the skin-closed surface 1131 of the wearing section and the second sub-air inlet 12a on the skin-distancing surface 1132 of the wearing section, air can be introduced from both sides. The first sub-air inlet 11a can introduce the air between the shell 11 and the neck into the volute 51, allowing the air between the shell 11 and the neck to flow faster, thus accelerating the heat dissipation or heat preservation effect of the neck. The second sub-air inlet 12a can introduce the air from the outside into the volute 51 with less resistance, reducing noise, and allowing sufficient air volume to enter the volute 51, effectively avoiding negative pressure imbalance.

[0115] With the first sub-air outlet 11b located on the skin-closed surface 1131 of the wearing section and the second sub-air outlet 12b located on the skin-distancing surface 1132 of the wearing section, air can be vented from both sides. When blowing cold air onto the neck through the first sub-air outlet 11b to dissipate heat, hot air can also be blown outward through the second sub-air outlet 12b to dissipate heat from the heating surfaces of the second temperature-conducting element 42 and the cooling element 3. Alternatively, when blowing hot air onto the neck through the first sub-air inlet 11a to keep the neck warm, cold air can also be blown outward through the second sub-air outlet 12b to conduct cold air to the cooling surfaces of the second temperature-conducting element 42 and the cooling element 3.

[0116] In addition, the first fan 5 can also introduce cold or hot air between the housing 11 and the neck of the human body into the volute 51 through the first sub-air inlet 11a, so as to reuse the cold or hot air and improve the cooling or heating efficiency of the neck air conditioner 10, so that the user can feel cooler or warmer when wearing the neck air conditioner 10.

[0117] In addition, a grille can be provided on the side of the volute 51 corresponding to the first sub-air inlet 11a to break up the airflow flowing from the first sub-air inlet 11a to the volute 51, so that the airflow through the first sub-air inlet 11a can be divided into multiple small airflows that enter the volute 51, effectively reducing airflow noise.

[0118] Optionally, such as Figure 11As shown, the first air outlet 1b is located on the skin-closed surface 1131 of the wearing section. Multiple protrusions 115 are provided on the skin-closed surface 1131 of the wearing section to form an air passage gap between the skin-closed surface 1131 of the wearing section and the skin when the neck air conditioner 10 is worn.

[0119] Therefore, through multiple protrusions 115, when wearing the neck air conditioner 10, an air passage gap is formed between the skin-friendly surface 1131 of the wearing section and the skin, so that the cold or hot air delivered from the first air outlet 1b can flow along the air passage gap, thereby quickly dissipating heat or keeping warm the neck, so that the user can feel cool or warm quickly when wearing the neck air conditioner 10.

[0120] Among them, multiple protrusions 115 can be arranged in rows on the skin-closed surface 1131 of the wearing section, so that when wearing the neck air conditioner 10, multiple air passage gaps can be formed between the skin-closed surface 1131 of the wearing section and the skin, so that the air can flow through more areas of the skin on the neck along the air passage gaps, thereby allowing the user to feel cool or warm more quickly.

[0121] In addition, the protrusion 115 can be a hemispherical structure or a columnar structure, and there is no limitation here.

[0122] The number of protrusions 115 can be two, three or more, and there is no limitation here.

[0123] Optionally, such as Figure 11 As shown, multiple protrusions 115 are arranged near or around the first air outlet 1b.

[0124] This allows cold or hot air to flow quickly through the air gap from the first air outlet 1b to other areas of the neck, thus enabling the user to feel cool or warm more quickly.

[0125] When multiple protrusions 115 are positioned near the first air outlet 1b, they can be positioned at intervals within the area where the first air outlet 1b is located, or they can be positioned near the first air outlet 1b. No limitation is made here.

[0126] When multiple protrusions 115 are arranged around the first air outlet 1b, they can be arranged at intervals around the first air outlet 1b so that multiple air passage gaps can be formed between the skin surface of the wearing section 113 and the skin.

[0127] For example, the first sub-air outlet 11b may include a plurality of air outlets, which are arranged in rows along the opposite direction of the two clamping arm sections 114. A plurality of protrusions 115 are provided on the side of the inner wall of the wearing section 113 away from the outer wall of the wearing section 113. The plurality of protrusions 115 are arranged in rows along the opposite direction of the two clamping arm sections 114, and a row of protrusions 115 is provided between each two adjacent rows of air outlets, or a row of air outlets is provided between each two adjacent rows of protrusions 115.

[0128] This allows for a more regular arrangement of several air outlets, facilitating the setting of several air outlets; similarly, it allows for a more regular arrangement of several protrusions 115, facilitating the setting of several protrusions 115.

[0129] In addition, multiple protrusions 115 may be arranged close to or around the first air inlet 1a so that the airflow between the skin-proximal surface 1131 of the wearing section and the skin can pass through the air gap more quickly through the first air inlet 1a and then flow into the volute 51.

[0130] Optionally, the side of the protrusion 115 that comes into contact with the skin is a convex spherical surface.

[0131] This allows the protrusion 115 to fit snugly against the skin of the neck, thus enabling comfortable wearing of the neck air conditioner 10.

[0132] In other embodiments, the side of the protrusion 115 that comes into contact with the skin can also be a cylindrical surface or a curved surface of other shapes. This is not limited here, as long as it is comfortable to wear the neck air conditioner 10.

[0133] like Figure 10 and Figure 12 As shown, the clamping arm section 114 has a receiving cavity 1141. The clamping arm section 114 is provided with a second air inlet 1c and a second air outlet 1d that communicate with the receiving cavity 1141. The neck-mounted air conditioner 10 also includes a second fan 7, which is disposed in the receiving cavity 1141.

[0134] Therefore, the neck air conditioner 10 can also introduce airflow from the second air inlet 1c into the accommodating cavity 1141 through the second fan 7, and can blow the airflow towards the second air outlet 1d, so that when wearing the neck air conditioner 10, it can blow air onto the human body part corresponding to the arm clip section 114, such as blowing air onto the head or the shoulder side of the neck, so that the neck air conditioner 10 can dissipate heat from multiple directions and in multiple ways, effectively improving the user's user experience.

[0135] The second air inlet 1c can be located on the near-skin surface 1142 of the clamping arm section, or on the far-skin surface 1143 of the clamping arm section, or it can be located on both the near-skin surface 1142 and the far-skin surface 1143 of the clamping arm section. No limitation is made here.

[0136] The second air outlet 1d can be located on the near-skin surface 1142 of the clamping arm section, or it can be located on both the near-skin surface 1142 and the far-skin surface 1143 of the clamping arm section. No limitation is made here.

[0137] The second fan 7 can be either a centrifugal fan or an axial fan, and there is no limitation on it.

[0138] The accommodating cavity 1141 is also provided with a clamping arm section air duct, which connects the air outlet of the second fan 7 and the second air outlet 1d. Several clamping arm section air guides are provided in the clamping arm section air duct, which extend along the flow direction of the air in the clamping arm section air duct. The several clamping arm section air guides are spaced apart to divide the clamping arm section air duct into multiple sub-air ducts. The air inlets of the multiple sub-air ducts are interconnected, and the air outlets of the multiple sub-air ducts correspond one-to-one with multiple areas of the second air outlet 1d, so that the air flowing out of the clamping arm section air duct can flow to multiple areas of the second air outlet 1d, so that the air outlet of each area of ​​the second air outlet 1d can be roughly the same, that is, the air outlet of the second air outlet 1d can be more uniform, which can provide users with more comfortable air and improve the user experience.

[0139] The number of air guide components in the clamp arm section can be one, two, or more, and there is no limit to this.

[0140] In addition, the neck-mounted air conditioner 10 also includes a battery, which is disposed in the accommodating cavity 1141. The battery is electrically connected to the first fan 5, the second fan 7 and the cooling component 3 respectively, so as to provide energy for the operation of the first fan 5, the second fan 7 and the cooling component 3.

[0141] The support may also include a partition 54 located between the battery and the air duct 2 to separate the partition 54 from the air duct 2.

[0142] Optionally, such as Figure 10 and Figure 12 As shown, the second air inlet 1c is disposed on the near-skin surface 1142 of the arm clip section, and / or the second air inlet 1c is disposed on the far-skin surface 1143 of the arm clip section; a first surface 1144 is connected between the near-skin surface 1142 and the far-skin surface 1143 of the arm clip section, the first surface 1144 being configured to face the head when wearing the neck air conditioner 10, and the second air outlet 1d is disposed on the first surface 1144.

[0143] Therefore, the first surface 1144 is configured to face the head when wearing the neck air conditioner 10, and the second air outlet 1d is disposed on the first surface 1144. Air can be blown towards the head of the human body through the second air outlet 1d, so that the neck air conditioner 10 can dissipate heat to the user from multiple directions and in multiple ways, which can make the cooling effect of the neck air conditioner 10 better and effectively improve the user's user experience.

[0144] The second air inlet 1c can be located on the near-skin surface 1142 of the clamping arm section, allowing the far-skin surface 1143 of the clamping arm section to form a relatively complete outer surface, thus improving the appearance of the clamping arm section 114. Alternatively, the second air inlet 1c can be located on the far-skin surface 1143 of the clamping arm section, allowing sufficient airflow to be introduced, thereby enabling the air delivered from the second air outlet 1d to have a large air volume, which can quickly dissipate heat from the user and improve the heat dissipation effect. Alternatively, the second air inlet 1c can be provided on both the near-skin surface 1142 and the far-skin surface 1143 of the clamping arm section, which can realize dual-sided air intake. This is not limited here, and the specific position of the second air inlet 1c can be set as needed.

[0145] In addition, the clamp arm section 114 also has a second surface opposite to the first surface 1144. The second surface is configured to face the shoulder side of the neck, thereby allowing air to be blown towards the shoulder side of the neck, so that the neck air conditioner 10 can dissipate heat to the user from more directions, thus making the cooling effect of the neck air conditioner 10 better.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
