[0022] Please see Figures 1 to 4 The present invention relates to a combined handheld fan 100, comprising a mobile charging device 1 and a handheld fan 2, wherein the handheld fan 2 and the mobile charging device 1 are separable from each other.

One side of the handheld fan 2 is close to one side of the mobile charging device 1 so that the charging interface 21 and the first power supply interface 11 are connected and conductive, thereby allowing the mobile charging device 1 to supply power to the handheld fan 2.

[0023] Please see again Figure 2 and Figure 3 The mobile charging device 1 also has a charging interface 12 on its other side, allowing an external power source to charge the mobile charging device 1. In this embodiment, the charging interface 12 is located on the rear end face of the mobile charging device 1. By providing the charging interface 12, the mobile charging device 1 can be charged independently after being detached from the handheld fan 2, thus improving ease of use. More specifically, the mobile charging device 1 also has several second power supply interfaces 14, located on the outer side between the front and rear ends of the mobile charging device 1; the second power supply interfaces 14 are USB, Type-C, etc. By providing the second power supply interfaces 14, the mobile charging device 1 can also supply power to other electrical devices, reducing battery anxiety and further improving ease of use.

[0024] Please see again Figure 4 The handheld fan 2 may or may not have a built-in battery. The handheld fan 2 includes a fan section 22 and a handle section 23, with the fan section 22 pivotally connected to the handle section 23, allowing the fan section 22 to bend relative to the handle section 23. This makes the airflow angle of the fan section 22 adjustable, effectively improving ease of use.

[0025] Please refer to 2 to Figure 6The first power supply interface 11 is one of a positive and negative magnetic male connector and a positive and negative magnetic female connector, and the charging interface 21 is the other of a positive and negative magnetic male connector and a positive and negative magnetic female connector; the positive and negative magnetic male connector and the positive and negative magnetic female connector cooperate and connect with each other through magnetic attraction. The magnetic connection between the positive and negative magnetic male connector and the positive and negative magnetic female connector allows the user to easily assemble or detach the mobile charging device 1 and the handheld fan 2, and also allows the handheld fan 2 to be stably connected to the mobile charging device 1 during use, providing support for the handheld fan 2, thus greatly improving the convenience of use. In this embodiment, the first power supply interface 11 is a positive and negative magnetic male connector, and the charging interface 21 is a positive and negative magnetic female connector. Specifically, the positive and negative magnetic charging male connector includes a first insulating body 111, a first conductive shell 112, a first conductive core 113, a first magnet 114, and a first connecting terminal 115. The first conductive core 113 is disposed at the center of the first insulating body 111, with one end penetrating through the front end of the first insulating body 111. The first conductive shell 112 wraps around the outer periphery and sides of the first insulating body 111 and is spaced apart from the first conductive core 113. The first magnet 114 is fixedly disposed on the front end surface of the first conductive shell 112 and makes conductive contact with the first conductive shell 112. The first connecting terminal 115 is fixedly disposed at the rear end of the first insulating body 111 and is electrically connected to the first conductive core 113. The first conductive core 113 and the first conductive shell 112 serve as the positive and negative poles of the positive and negative magnetic charging male connector, respectively. The first conductive core 113 and the first conductive shell 112 are electrically connected to the positive and negative poles of the battery in the mobile charging device, respectively. The positive and negative magnetic chuck includes a second insulating body 211, a second conductive outer shell 212, a second conductive core 213, and a second magnet 214. The second conductive core 213 is fixed to the center of the second insulating body 211, with both ends protruding from the ends of the second insulating body 211. The second conductive outer shell 212 wraps around the outer peripheral surface and sides of the second insulating body 211 and is spaced apart from the second conductive core 213. The second magnet 214 is fixedly disposed on the front end surface of the second conductive outer shell 212 and is in conductive contact with it. The second conductive core 213 and the second conductive outer shell 212 serve as the positive and negative poles of the positive and negative magnetic chuck, respectively. The second conductive core 213 and the second conductive outer shell 212 are respectively electrically connected to the positive and negative terminals of the handheld fan. The front end of the first magnet 114 has the opposite polarity to the front end of the second magnet 214.When the positive and negative magnetic male connectors are connected to the positive magnetic female connector, the first magnet 114 and the second magnet 214 attract each other and conduct electricity, and the first conductive core 113 and the second conductive core 213 cooperate and conduct electricity together. The front end surface of the conductive core has a recess. The front end surface of the conductive core has a protrusion; the recess and the protrusion cooperate and make electrical contact.

[0026] For example Figure 6 As shown, specifically, the first conductive core 113 is retractably disposed within the first insulating body 111. The positive and negative magnetic male and female connectors further include an elastic element 116, which is disposed between the first conductive core 113 and the first connecting terminal 115 and located inside the first insulating body, so that the first conductive core 113 slides out of the front end of the first insulating body 111. The elastic element 116 is electrically connected to both the first conductive core 113 and the first connecting terminal 115. The elastic element 116 is a compression spring and is made of conductive material. By providing the elastic element 116, a buffer can be generated when the first conductive core 113 and the second conductive core 213 come into contact, thereby both maintaining contact between the two and protecting the first conductive core 113 and the second conductive core 213, making the connection between the positive and negative magnetic male and female connectors more stable.

[0027] In some embodiments, the first magnet 114 may not be disposed on the positive and negative magnetic male and female bases. Specifically, the handheld fan 2 has a first magnet on the side facing the mobile charging device 1. The mobile charging device 1 has a second magnet on the side facing the handheld fan 2. The first magnet and the second magnet attract each other, which also allows the handheld fan 2 to be connected to the mobile charging device 1. By utilizing the mutual attraction between the first magnet and the second magnet, the user can easily combine or disassemble the mobile charging device 1 and the handheld fan 2, greatly improving the convenience of use.

[0028] Compared with existing technologies, this utility model separates the handheld fan 2 and the mobile charging device 1. A first power supply interface 11 is provided on one side of the mobile charging device 1, and a charging interface 21 is provided on one side of the handheld fan 2. The charging interface 21 and the first power supply interface 11 are connected and conductive, allowing the mobile charging device 1 to be combined with the handheld fan 2 and supply power to it. This detachable combination makes connection very simple. It achieves both the portability of the traditional handheld fan 2 and the replaceability of the mobile charging device 1. Users only need two mobile charging devices 1: one connected to the handheld fan 2 and the other for charging, alternating between them. This solves the problem of short battery life in traditional handheld fans 2, greatly improving usability. Furthermore, by incorporating a high beam 13 and a soft light 15 into the mobile charging device 1, it functions as a flashlight and a desk lamp, increasing the functionality of the combined handheld fan 100 and further enhancing its ease of use.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
