[0050] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.

[0051] Example 1

[0052] refer to Figures 1 to 13 A neck-hanging fan includes a neck-hanging body 1. A cylindrical first air guide cavity 2 protrudes from the lower end of the neck-hanging body 1. The first air guide cavity 2 includes a first air inlet 22 disposed at the lower end of the neck-hanging body 1 and a first air outlet 23 disposed opposite to the first air inlet 22. The neck-hanging body 1 includes an inner end 11 that contacts the neck of the user. The first air outlet 23 faces the inner end 11. A first fan assembly 3 is located within the first air guide cavity 2 and is used to drive airflow from the first air inlet 22 through the first air outlet 23 to the inner end 11. With this structure, because the first air guide cavity 2 is cylindrical, the neck-hanging fan forms a vertically blowing direct-flow fan. The first fan assembly 3 can drive airflow from the first air inlet 22 through the first air outlet 23 to the inner end 11, greatly improving the blowing efficiency. Users can more directly feel the cool airflow blowing directly onto their neck when using the neck-hanging fan, improving the overall performance of the fan. Furthermore, since the first air guide cavity 2 is a straight cylindrical cavity that is integrally formed and protrudes from the neck hanger body 1, this design enhances the overall aesthetics and design of the product, and helps to improve the wearing comfort of the neck hanger fan, thereby improving the overall quality of the product and the user experience.

[0053] In this embodiment, the neck fan has a recessed first air guide 12, which extends from the first air outlet 23 to the inner end portion 11. The first fan assembly 3 drives airflow to exit from the first air outlet 23 and blow it along the first air guide 12 toward the inner end portion 11. Furthermore, the inner end portion 11 is connected to a flexible first neck support portion 111, and a first air inlet gap 121 is formed between the first neck support portion 111 and the inner end portion 11. The first fan assembly 3 drives airflow to exit from the first air outlet 23 and blow it along the first air guide 12 toward the first air inlet gap 121. The first neck support portion 111 can be a silicone neck support portion, a plastic neck support portion, a rubber neck support portion, etc. With the above structure, when the airflow is blown out from the first air outlet 23, under the guidance of the concave first air guide 12, the airflow will blow along the first air guide 12 toward the inner end 11. And due to the first air inlet gap 121, the airflow can be blocked in the gap, so that when the user wears the neck fan, he / she can feel the airflow at the inner end 11 more strongly, which enhances the heat dissipation effect. In addition, the flexible neck support provides the user with a more comfortable support effect, improving the user experience.

[0054] In this embodiment, the width of the first air guide path gradually decreases towards the inner end of the first air outlet; the width of the first air guide path ranges from 1 to 5 cm; the length of the first air guide path ranges from 8 to 16 cm; and the depth of the first air guide path ranges from 0 to 3 cm.

[0055] In this embodiment, the neck hanger body 1 is a U-shaped neck hanger body 1. The neck hanger body 1 includes a first fan part 101, a second fan part 102, and a connector 103. The first fan part 101 and the second fan part 102 are detachably connected by the connector 103. The connector is a flexible connector 103. Specifically, the connector 103 can be a silicone connector, a plastic connector, a rubber connector, etc.

[0056] In this embodiment, the first fan portion 101 includes a first outer shell 1011 and a first inner shell 1012. A first air guide 12 is disposed in the first inner shell 1012, and the first inner shell 1012 and the first outer shell 1011 are detachably connected by a snap-fit. This allows the user to easily open and install the first fan portion 101, facilitating user maintenance.

[0057] In this embodiment, the diameter of the first air inlet 22 is in the range of 30mm-60mm, and the diameter of the first air outlet 23 is in the range of 30mm-60mm. This appropriate diameter range helps to achieve a balanced airflow, allowing the fan to provide sufficient airflow to maintain a high cooling effect. It also contributes to a more rational overall structure, making it easier to carry and use.

[0058] In this embodiment, the lower end of the neck fan is further provided with a cylindrical second air guide cavity 4. The second air guide cavity 4 includes a second air inlet 42 disposed at the lower end of the neck body 1 and a second air outlet 43 disposed opposite to the second air inlet 42. The second air outlet 43 is disposed towards the inner end 11. A second fan assembly 5 is disposed inside the second air guide cavity 4. The second fan assembly 5 is used to drive airflow from the second air inlet 42 through the second air outlet 43 to the inner end 11. With the above structure, since the second air guide cavity 4 is cylindrical, the neck fan forms a vertically blowing direct-blowing fan, which allows the second fan assembly 5 to drive airflow from the second air inlet 42 through the second air outlet 43 to the inner end 11, greatly improving the blowing efficiency. Users can more directly feel the cool wind when using the neck fan, improving the overall performance of the fan. Furthermore, since the second air guide cavity 4 is a straight cylindrical cavity that is integrally formed and protrudes from the neck hanger body 1, this design enhances the overall aesthetics and design of the product, and helps to improve the wearing comfort of the neck hanger fan, thereby improving the overall quality of the product and the user experience.

[0059] In this embodiment, the neck fan has a recessed second air guide 13, which extends from the second air outlet 43 to the inner end portion 11. The second fan assembly 5 drives airflow to exit from the second air outlet 43 and blow it along the second air guide 13 toward the inner end portion 11. Furthermore, the inner end portion 11 is connected to a flexible second neck support 112, and a second air inlet gap 131 is formed between the second neck support 112 and the inner end portion 11. The second fan assembly 5 drives airflow to exit from the second air outlet 43 and blow it along the second air guide 13 toward the second air inlet gap 131. The second neck support 112 can be a silicone neck support, a plastic neck support, a rubber neck support, etc. With the above structure, when the airflow is blown out from the second air outlet 43, under the guidance of the concave second air guide 13, the airflow will blow along the second air guide 13 to the inner end 11. And due to the second air inlet gap 131, the airflow can be blocked in the gap, so that when the user wears the neck fan, he / she can feel the airflow at the inner end 11 more strongly, which enhances the heat dissipation effect. In addition, the flexible neck support provides the user with a more comfortable support effect, improving the user experience.

[0060] In this embodiment, the second fan portion 102 includes a second outer shell 1021 and a second inner shell 1022. The second air guide 13 is disposed in the second inner shell 1022, and the second inner shell 1022 and the second outer shell 1021 are detachably connected by a snap-fit. This allows the user to easily open and install the second fan portion 102, facilitating user maintenance.

The outer diameter of the first hook portion 1412 is larger than the outer diameter of the first post body 1411 to prevent the first fixing post 141 from disengaging from the first fixing hole 142. The second fixing post 143 includes a second post body 1431 and a second hook portion 1432 connected to the end of the second post body 1431 away from the flexible connecting portion 103a. The outer diameter of the second hook portion 1432 is larger than the outer diameter of the second post body 1432 to prevent the second fixing post 143 from disengaging from the second fixing hole 144.

[0076] In one embodiment, the first fixing hole 142 includes a first portion 1421 corresponding to the first column 1411 and a second portion 1422 corresponding to the first hook 1412, wherein the diameter of the second portion 1422 is larger than the diameter of the first portion 1421; the second fixing hole 144 includes a third portion 1441 corresponding to the second column 1431 and a fourth portion 1442 corresponding to the second hook 1432, wherein the diameter of the fourth portion 1442 is larger than the diameter of the third portion 1441.

[0077] In one embodiment, the connector 103 may also be provided with at least one neck support (such as a first neck support 111 and a second neck support 112). The at least one neck support is connected to the inner side of the flexible connector 103a that is close to the human neck. The at least one neck support is used to form at least one air inlet gap with the first fan portion 101 or the second fan portion 102, so that the air from the first fan portion 101 or the second fan portion 102 can enter the air inlet gap (such as 121, 131), thereby avoiding the situation where the human neck is in direct contact with the first fan portion 101 or the second fan portion 102, resulting in the air not being able to be provided to the surface of the neck skin.

[0078] As previously shown, in this embodiment, the at least one neck support includes a first neck support 111 and a second neck support 112. The first neck support 111 is disposed adjacent to the first fan portion 101 and is used to form a first air inlet gap 121 between itself and the first fan portion 101. The second neck support 112 is disposed adjacent to the second fan portion 102 and is used to form a second air inlet gap 131 between itself and the second fan portion 102.

[0079] In one embodiment, the surfaces of the first neck support portion 111 and the second neck support portion 112 away from the flexible connection portion 103a also have a plurality of protrusions 103b. The plurality of protrusions 103b are used to create a gap between the at least one neck support portion and the skin of the human neck, and also to prevent the human neck from directly contacting the first fan portion 101 or the second fan portion 102, which would prevent air from being delivered to the surface of the neck skin.

[0080] It can be seen that the surfaces of the first neck support 111 and the second neck support 112 away from the flexible connecting part 103a are arc-shaped surfaces, and the size of the plurality of protrusions 103b can gradually decrease from the middle to both ends along the vertical direction D4 perpendicular to the extension direction D1, thereby achieving a more comfortable wearing effect.

[0081] In this embodiment, the flexible connecting part 103a, the first neck support part 111 and the second neck support part 112 are all made of flexible materials. If they are all made of the same flexible material (such as flexible silicone material) and are integrally molded, a more comfortable wearing effect can be achieved.

[0082] Further, the flexible connection portion 103a includes a main body portion 103d, a first extension portion 103e, and a second extension portion 103f. The main body portion 103d has at least one mounting hole 1031. The first extension portion 103e and the second extension portion 103f are respectively connected to the two ends of the main body portion 103d, and the first extension portion 103e and the second extension portion 103f protrude from the main body portion 103d along the extension direction D1. The first extension portion 103e and the second extension portion 103f are respectively used to cover the inner surface of the first connection end 1013 and the inner surface of the second connection end 1023 that are close to the neck of the human body. The first fixing structure and the second fixing structure are respectively disposed in the first extension 103e and the second extension 103f, so that the first fixing structure and the second fixing structure are close to the inner side of the human neck, and the first anti-detachment structure and the second anti-detachment structure are located on the outer side away from the human neck. The inner and outer cooperation can make the connector 103 reliably connect the first fan part 101 and the second fan part 102, and prevent the connection from easily detaching.

[0083] In this embodiment, the first air guide cavity 2 is located inside the first fan portion 101, and the first fan portion 101 is also provided with a first mounting cavity 1014, and the first power supply component 8 is located inside the first mounting cavity 1014; the second air guide cavity 4 is located inside the second fan portion 102, and the second fan portion 102 is also provided with a second mounting cavity 1024, and the second power supply component 9 is located inside the second mounting cavity 1024.

[0084] In this embodiment, the first fan section 101 is further provided with a first push-button switch 1015, a first charging interface 1016, and a first indicator light module 1017.

The first button switch 1015 and the first indicator light module 1017 are electrically connected to the first main control module 814. The first indicator light module 1017 is used to indicate whether the neck fan is on or off.

[0088] In this embodiment, the neck fan also includes a second charging control module 921, a second battery protection module 922, a second charging indicator module 923, a second main control module 924, and a second boost module 925, all electrically connected to the second circuit board 92.

The second charging indicator module 923 is used to display the charging status. The second battery protection module 922 is electrically connected to the second charging control module 921 and the second battery 91 to protect the second battery 91.

[0090] The second main control module 924, the second boost module 925, and the second motor 52 are all electrically connected to the second battery 91. The second button switch 1025 and the second indicator module 1027 are electrically connected to the second main control module 924. The second indicator module 1027 is used to indicate whether the neck fan is on or off.

[0091] In this embodiment, the first fan section 101 is provided with a first conductive terminal 1018, and the second fan section 102 is provided with a second conductive terminal 1019. The first conductive terminal 1018 and the second conductive terminal 1019 are connected. The first push-button switch 1015 is electrically connected to the first main control module 814 and the second main control module 924 respectively. The second push-button switch 1025 is electrically connected to the first main control module 814 and the second main control module 924 respectively. The first push-button switch 1015 or the second push-button switch 1025 is used to send a third fan working signal.

[0092] The first main control module 814 is used to receive the working signal of the third fan and drive the first boost module 815 to receive and increase the output voltage of the first battery 81 so as to drive the first motor 32 to work.

[0093] The second main control module 924 is used to receive the working signal of the third fan and drive the second boost module 925 to receive and increase the output voltage of the second battery 91 to drive the second motor 52 to work.

[0094] In this embodiment, the first fan part 101 and the second fan part 102 can be regarded as two independent fans electrically connected to form a neck fan, wherein the circuit diagrams of the various circuit modules contained in the two independent fans are the same.

[0095] With the above structure, the first fan part 101 and the second fan part 102 are combined to form a complete U-shaped neck fan. At this time, the first conductive end 1018 and the second conductive end 1019 are connected. Regardless of whether the user presses the first button switch 1015 or the second button switch 1025, a third fan working signal can be emitted. When the first main control module 814 receives the third fan working signal, it drives the first boost module 815 to receive and increase the output voltage of the first battery 81, thereby driving the first motor 32 to work.

The first main control module 814 can also adjust the speed of the first motor 32 by controlling the output voltage of the first boost module 815.

[0103] In this embodiment, the second fan section 102 includes a second charging control module 921, a second battery protection module 922, a second charging indicator module 923, a second main control module 924, and a second boost module 925, which are electrically connected to the second circuit board 92.

[0107] Example 3

[0108] refer to Figures 17 to 20 The neck-hanging body 1 includes an inner end 11 that contacts the neck of the human body, and a first receiving cavity 15 is provided inwardly on the side of the lower end of the neck-hanging body 1 near the inner end.

[0109] The first fan assembly 3 includes a cylindrical first fan housing 31, which is detachably connected to the neckband body 1 and located in the first receiving cavity 15. The first fan housing 31 has a third air inlet 311 and a third air outlet 313. The first fan assembly 3 is used to drive airflow from the third air inlet 311 through the third air outlet 313 to the inner end 11.

[0110] With the above structure, since the first fan housing 31 is cylindrical, the neck fan forms a vertically blowing direct-blowing fan. The first fan assembly 3 can drive airflow from the third air inlet and through the third air outlet to the inner end 11, greatly improving the blowing efficiency. When using the neck fan, the user can more directly feel the cool air blowing directly onto the neck, improving the overall performance of the fan. Furthermore, since the first fan housing and the neck hanger body can be disassembled and assembled, they can be processed and assembled separately during the production process, improving production efficiency, reducing production costs, and also facilitating storage and transportation, thus improving the product's portability.

[0111] In this embodiment, the neckband body 1 has several connecting slots 151 on its inner side near the first receiving cavity 15, and the outer wall of the first fan housing 31 has several connecting buckles 315 that match and engage with the connecting slots 151. The first fan housing 31 and the neckband body 1 are detachably connected by the buckles. Specifically, the connecting slots 151 are symmetrically distributed on the inner side of the neckband body 1, with six sets of connecting slots 151, and two connecting slots 151 in each set; the connecting buckles 315 are symmetrically distributed on the outer wall of the first fan housing 31, with six sets of connecting buckles 315, and two connecting buckles 315 in each set. With the above structure, the user can manually install or remove the first fan housing from the neckband body. The six sets of buckle engagement structure ensure the firmness of the splicing and prevent the first fan housing from detaching during wear and use, thus improving the safety and convenience of the neckband fan.

[0112] In this embodiment, the neckband body 1 is detachably connected to the outer side away from the first receiving cavity 15 with a first outer cover 16.

The first mesh 3111 can prevent hair or debris from being sucked into the first fan housing, avoiding damage to the fan assembly and reducing the airflow force. The first concentrating ring 3131 can concentrate the airflow directed towards the neck, improving the airflow performance.

[0114] In this embodiment, a first conductive through hole 152 is provided on the inner side of the neckband body near the first receiving cavity 15.

After the wire of the first fan assembly 3 is connected, the first fan housing is spliced ​​with the neck body through the connection buckle 315 and the connection slot 151, and finally a direct-blowing neck fan that is conductive to the neck body and easy to install is obtained.

[0116] In this embodiment, a second receiving cavity 17 is recessed inward on the side of the lower end of the neck hanger body opposite to the first receiving cavity 15; it also includes a second fan assembly 5, which includes a cylindrical second fan housing. The second fan housing is detachably connected to the neck hanger body and located within the second receiving cavity 17. The second fan housing has a fourth air inlet 511 and a fourth air outlet 513. The second fan assembly 5 is used to drive airflow from the fourth air inlet 511 through the fourth air outlet 513 to the inner end. Through the above structure, similarly, since the second fan housing 51 is cylindrical, the neck hanger fan forms a vertically blowing direct-blowing fan. The second fan assembly can drive airflow from the fourth air inlet 511 through the fourth air outlet 511 to the inner end 11, greatly improving the blowing efficiency. When using the neck hanger fan, the user can more directly feel the cool wind blowing directly to the neck, improving the overall performance of the fan. Furthermore, since the second fan housing 51 and the neck hanger body 1 can be disassembled and assembled, they can be processed and assembled separately during the production process, which improves production efficiency, reduces production costs, and facilitates storage and transportation, thus improving the portability of the product.

[0117] In this embodiment, the neck hanger body has a plurality of connecting slots 151 on its inner side near the second receiving cavity 17, and the outer wall of the second fan housing 51 has a plurality of connecting buckles 315 that match and engage with the connecting slots 151.

[0120] In this embodiment, a second conductive through hole 171 is provided on the inner side of the neck hanger body near the second receiving cavity 17. The second conductive through hole 171 is used for the wires of the second fan assembly 5 to pass through and to communicate with the second power supply assembly 9.

[0121] With the above structure, after assembling the first fan housing 31, the second fan housing 51 is installed in the same way. First, the second outer cover 18 is opened, and then the wires of the second fan assembly 5 are passed through the second conductive through hole 171 and connected to the second power supply assembly 9 in the second mounting cavity 1024. Then, the second outer cover 18 is closed. After the wires of the second fan assembly 5 are connected, the second fan housing 51 is spliced ​​to the neck hanger body 1 by the snap-fit ​​of the connecting buckle 315 and the connecting slot 151, and finally a direct-blowing neck hanger fan that is conductive to the neck hanger body 1 and easy to install is obtained.
