It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This application provides a handheld fan that, by setting the connecting arm into a first part and a second part that are independently set, the first part connecting the fan housing and the handheld housing, and the second part connecting the first part to form a communicating space connecting the handheld housing and the fan housing, allows wires to be threaded through the communicating space to connect the electrical connection parts inside the fan housing and the electrical connection parts inside the handheld housing. Correspondingly, by removing the second part from the first part, the wiring can be exposed for inspection and maintenance, thereby facilitating the maintenance of the wiring.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please see Figure 1 and Figure 2 This application provides a handheld fan 1000, which includes a fan housing 100, a handheld housing 200, and a connecting arm 300.

[0037] The fan housing 100 provides mounting space for the fan blades, drive module and other components, while the handheld housing 200 is used for user gripping and provides mounting space for the battery, circuit board and other components.

[0038] Both the fan housing 100 and the handheld housing 200 can have various shapes, including standard cylindrical, elliptical cylindrical, prismatic, cuboid, and other shapes. Furthermore, both the fan housing 100 and the handheld housing 200 can be formed in various ways. They can be single, complete components formed by machining, molding, 3D printing, or other processing methods. They can also be assembled from multiple components, which can be fixed together by fastening, bonding, ultrasonic welding, or other methods. Other methods can also be used to form both the fan housing 100 and the handheld housing 200; specific limitations are not specified here.

[0039] The connecting arm 300 is used to connect the handheld housing 200 and the fan housing 100 together and to support the fan housing 100. The connecting arm 300 includes a first part 310 and a second part 320 that are independently arranged. The first part 310 connects the fan housing 100 and the handheld housing 200 and is integrally formed with the handheld housing 200. The second part 320 is connected to the first part 310 and forms a communicating space 301 that connects the handheld housing 200 and the fan housing 100.

[0040] Furthermore, the connecting arm 300 is located between the plane of the front and the plane of the back of the handheld housing 200, so that the connecting arm 300 does not extend beyond the front and back of the handheld housing 200, which is beneficial for the compact design of the handheld fan 1000. In addition, in other embodiments, the connecting arm 300 may also be positioned beyond the front or back of the handheld housing 200.

[0041] It should be noted that both the first part 310 and the second part 320 can be configured to include one shell, or both can include multiple shells. The number of shells included in the first part 310 and the number of shells included in the second part 320 can be the same or different. For example, both the first part 310 and the second part 320 may include one shell, or the first part 310 may include two shells and the second part 320 may include one shell, with the three shells connected to form the aforementioned connected space 301. In this embodiment and the accompanying drawings, the first part 310 and the second part 320 are described with each of them including one shell.

[0042] There are many ways to integrate the first part 310 and the handheld housing 200. They can be formed by injection molding, rotational molding, or other integrated molding methods such as 3D printing. No specific limitations are made here.

[0043] In this embodiment, the first part 310 is integrally formed with the handheld housing 200, which enhances the structural strength of the first part 310. In other embodiments, the first part 310 may also be partially integrally formed with the handheld housing 200.

[0044] Furthermore, in this embodiment, the fan housing 100 and the handheld housing 200 are connected by a connecting arm 300. This configuration simplifies the structure of the handheld fan 1000 by enabling the connection between the fan housing 100 and the handheld housing 200 with a single connecting arm 300. In other embodiments, the fan housing 100 and the handheld housing 200 can also be connected by multiple connecting arms 300. For example, the fan housing 100 and the handheld housing 200 can be connected by two connecting arms 300, with the first ends of the two connecting arms 300 located on the left and right sides of the handheld housing 200, and the second ends of the two connecting arms 300 located on the left and right sides of the fan housing 100, respectively. Of course, in other embodiments, multiple fan housings 100 can also be connected by a single connecting arm 300.

[0045] When connecting the electrical connection parts inside the fan housing 100 and the handheld housing 200 with a wire, first connect one end of the wire to the electrical connection part inside the fan housing 100, then pass the other end of the wire through the corresponding position of the first part 310 and extend it into the handheld housing 200 to connect with the electrical connection part inside the handheld housing 200. Finally, connect the second part 320 to the first part 310 so that the wire is located in the connecting space 301 formed by the two, thus completing the connection between the electrical connection parts inside the fan housing 100 and the handheld housing 200. When it is necessary to repair the circuit, the second part 320 can be removed from the first part 310 to expose the circuit for repair. After the repair is completed, the second part 320 can be reinstalled, thus making the repair of the circuit convenient.

[0046] There are many possible connection positions and methods between the first part 310 and the handheld housing 200, and between the first part 310 and the fan housing 100. Please refer to [link / reference needed]. Figure 1 and Figure 2 In one embodiment of this application, one end of the first part 310 is fixedly connected to the upper part of the handheld housing 200, and the other end of the first part 310 is rotatably connected to the circumferential side of the fan housing 100. This rotatable connection is a damped rotatable connection. This arrangement allows the first part 310 to be connected to the handheld housing 200 at a position where the handheld housing 200 is close to the fan housing 100, thereby shortening the length of the connecting arm 300. It also allows the fan housing 100 to be rotated relative to the connecting arm 300, thereby adjusting the airflow direction of the fan housing 100.

[0047] Specifically, the connection point between the first part 310 and the handheld housing 200 is located at the connection between the upper end face and the side face of the handheld housing 200. That is, one part of the connection point between the first part 310 and the handheld housing 200 is located at the edge of the upper end face of the handheld housing 200, and the other part of the connection point between the first part 310 and the handheld housing 200 is located at the edge of the side face of the handheld housing 200. This arrangement can increase the connection strength between the first part 310 and the handheld housing 200, and also enable the first part 310 to have support from both the upper end face and the side face of the handheld housing 200, which is beneficial for supporting the fan housing 100 through the connecting arm 300.

[0048] In other embodiments, the connection position between the first part 310 and the handheld housing 200 may also be located at the upper side of the handheld housing 200 or at the middle of the side of the handheld housing 200; the connection position between the first part 310 and the fan housing 100 may also be located at the top or bottom of the fan housing 100 in the circumferential direction; the connection method between the first part 310 and the fan housing 100 may also be an integral connection, that is, the first part 310 and the fan housing 100 are integrally formed; the connection method between the first part 310 and the fan housing 100 may also be a fixed connection or a detachable connection as described below.

[0049] There are many ways to form the aforementioned connected space 301; please refer to [link / reference]. Figures 2 to 5 In one embodiment of this application, the first part 310 and the fan housing 100 surround a chamber 311 with one side open, and the second part 320 covers the open end of the chamber 311 to form a communicating space 301. This arrangement can form a completely closed communicating space 301 and also makes the formation of the communicating space 301 convenient.

[0050] Specifically, please refer to Figures 2 to 4 The bottom wall of the chamber 311 is provided with a first communication port 312 that communicates with the corresponding position of the handheld housing 200, and the handheld housing 200 is provided with a second communication port 313 that communicates with the bottom wall of the chamber 311, so that the first communication port 312, the communication space 301 and the second communication port 313 form a passage for wires to pass through.

[0051] In this embodiment, the open end of the chamber 311 is located on the side of the first part 310 facing away from the fan housing 100. This ensures that the open end of the chamber 311 is not obstructed by other components, facilitating both the removal of the second part 320 from the first part 310 and the maintenance of the wiring within the chamber 311. Furthermore, in other embodiments, the open end of the chamber 311 may also be located on the side of the first part 310 facing the fan housing 100, or it may be located on the side of the first part 310 near the front or back of the handheld housing 200.

[0052] In other embodiments, a chamber 311 with an open side can be recessed directly on the first part 310, and the second part 320 can cover the open end of the chamber 311 to form a communicating space 301. Alternatively, the first part 310 can have a first chamber 311 recessed, and the second part 320 can have a second chamber 311 recessed. After the first part 310 and the second part 320 are connected, the first chamber 311 and the second chamber 311 form a communicating space 301.

[0053] To enhance the connection strength between the connecting arm 300 and the handheld housing 200, please refer to... Figure 4In one embodiment of this application, the bottom wall of the chamber 311 includes a first bottom wall 314 and a second bottom wall 315 connected at an angle. The first bottom wall 314 is located on the first part 310, and the second bottom wall 315 is located on the handheld housing 200. The first bottom wall 314 and the second bottom wall 315 are connected by a reinforcing rib 316.

[0054] Specifically, there are two reinforcing ribs 316 arranged in parallel. Each reinforcing rib 316 extends along the extension direction of the first part 310, and the connection port is located between the two reinforcing ribs 316 on the side near the second bottom wall 315. This can further enhance the connection strength between the connecting arm 300 and the handheld housing 200.

[0055] Furthermore, the reinforcing rib 316 is connected to the first part 310 in the second part 320 and abuts against the inner side of the second part 320, so that the reinforcing rib 316 can also support the second part 320, thereby enhancing the structural strength of the second part 320.

[0056] In this embodiment, both the first bottom wall 314 and the second bottom wall 315 are curved surfaces. This increases the connection area between the reinforcing rib 316 and the first bottom wall 314 and the second bottom wall 315, thereby enhancing the connection strength between the connecting arm 300 and the handheld housing 200. In other embodiments, both the first bottom wall 314 and the second bottom wall 315 can be flat surfaces, or one of the first bottom wall 314 and the second bottom wall 315 can be curved and the other flat.

[0057] To ensure stable support of the fan housing 100 via the connecting arm 300, please refer to... Figure 1 In one embodiment of this application, the connecting arm 300 includes a first segment 300a and a second segment 300b connected to each other. The first segment 300a is vertically arranged in the vertical direction, and the second segment 300b is inclined in the vertical direction. The end of the first segment 300a away from the second segment 300b is connected to the fan housing 100, and the end of the second segment 300b away from the first segment 300a is connected to the handheld housing 200. Specifically, the first segment 300a is formed by combining a portion of the first part 310 and the second part 320, and the second segment 300b is formed by combining the other part of the first part 310 and the second part 320.

[0058] Specifically, the first segment 300a and the second segment 300b are connected at an obtuse angle. The angle between the first segment 300a and the second segment 300b can be any other value, such as 100 degrees, 101 degrees, 102 degrees, 103 degrees, 104 degrees, 105 degrees, 106 degrees, 107 degrees, 108 degrees, 109 degrees, or 110 degrees. No specific limit is imposed here.

[0059] Through the above technical solution, by setting the first segment 300a and the second segment 300b, the connection between the first segment 300a and the second segment 300b and the connection between the second segment 300b and the handheld housing 200 are formed as two support positions. The fan housing 100 is supported by the two support positions, and thus the fan housing 100 can be stably supported by the connecting arm 300.

[0060] Furthermore, the width of the second segment 300b gradually narrows from the end closest to the handheld housing 200 to the end furthest from the handheld housing 200. This design makes the vertical cross-section of the second segment 300b approximately triangular, thereby enhancing the support strength of the second segment 300b for the first segment 300a, that is, enhancing the support strength of the connection between the second segment 300b and the first segment 300a for the fan housing 100.

[0061] There are many ways to connect the first part 310 and the second part 320 mentioned above; please refer to [link / reference]. Figure 1 In one embodiment of this application, the first part 310 and the second part 320 are fixedly connected. Specifically, the fixed connection is made in a way that can be released with the help of tools, and there are many ways to make the fixed connection. It can be adhesive bonding, in which case the adhesive joint between the second part 320 and the first part 310 can be heated by other tools such as a hot air gun or a high-temperature hair dryer to release the adhesive between the two, so that the second part 320 can be removed from the first part 310. It can also be ultrasonic welding, in which case the joint between the second part 320 and the first part 310 can be heated by other tools such as a hot air gun or a high-temperature hair dryer to loosen the joint, so that the second part 320 can be removed from the first part 310.

[0062] In another embodiment of this application, the first part 310 and the second part 320 are detachably connected. The detachable connection can be one or more of the following detachable connection methods: snap-fit ​​connection, snap-on connection, threaded connection, magnetic connection, tenon and mortise connection, etc.

[0063] When the first part 310 and the second part 320 are connected by a snap-fit, please refer to Figures 2 to 5 In one embodiment of this application, the first part 310 is provided with a first snap-fit ​​structure 317, and the second part 320 is provided with a second snap-fit ​​structure 321 that cooperates with the first snap-fit ​​structure 317.

[0064] There are many types of the first snap-fit ​​structure 317 and the second snap-fit ​​structure 321 described above. Please refer to [link / reference]. Figure 4 and Figure 5In one embodiment of this application, the first snap-fit ​​structure 317 includes two snap-fit ​​positions 3171. One snap-fit ​​position 3171 is located on the side of the first part 310 away from the handheld housing 200, and the other snap-fit ​​position 3171 is located on the handheld housing 200. The second snap-fit ​​structure 321 includes two snap-fits 3211. The two snap-fits 3211 are respectively located on both sides of the extension direction of the second part 320. Each snap-fit ​​position 3171 cooperates with the corresponding snap-fit ​​3211. This arrangement enables the two sides of the extension direction of the first part 310 to be snapped into the two sides of the extension direction of the second part 320, thereby making the snap-fit ​​between the first part 310 and the second part 320 stable.

[0065] Specifically, please refer to Figure 4 and Figure 5 The first part 310 has one buckle 3171, and the handheld housing 200 has two buckles 3171 arranged in parallel. Correspondingly, the buckle 3211 is set to three, and each buckle 3211 cooperates with the corresponding buckle 3171, which can enhance the connection strength between the first part 310 and the second part 320.

[0066] To further enhance the connection strength between the first part 310 and the second part 320, please refer to Figure 4 and Figure 5 The first snap-fit ​​structure 317 further includes a snap-fit ​​member 3172, which is disposed in the first part 310 and forms an insertion groove 3173 between it and the inner surface of the first part 310. The second snap-fit ​​structure 321 further includes an insertion member 3212 disposed on the second part 320, which cooperates with the insertion groove 3173.

[0067] Specifically, please refer to Figure 4 and Figure 5 Two snap-fit ​​pieces 3172 are provided, each extending along the extension direction of the first part 310. The two snap-fit ​​pieces 3172 form two insertion slots 3173 between the two inner walls of the first part 310 in the width direction. Two insertion pieces 3212 are provided, and the two insertion pieces 3212 are inserted into the two insertion slots 3173. This allows the two sides of the first part 310 in the width direction to be fixed to the two sides of the second part 320 in the width direction, thereby improving the snap-fit ​​stability of the first part 310 and the second part 320.

[0068] To further enhance the connection strength between the first part 310 and the second part 320, please refer to Figure 4 and Figure 5 The first snap-fit ​​structure 317 further includes a fastening member 3174 disposed between the two ends of the first part 310 in the extending direction, and the second snap-fit ​​structure 321 includes a snap fastening member 3213 disposed in the second housing, and the snap fastening member 3213 cooperates with the fastening member 3174.

[0069] Specifically, please refer to Figures 5 to 7 The fastener 3174 is provided on the bottom wall of the chamber 311. The fastener 3174 and the bottom wall of the chamber 311 form a first groove 31741. The side of the fastener 3174 facing away from the bottom wall of the chamber 311 is provided with a second groove 31742. The bottom wall of the second groove 31742 is through, so that the second groove 31742 and the first groove 31741 are connected. The latching member 3213 is fastened to the side wall of the second groove 31742 and the inner wall of the first groove 31741. This makes it convenient for the latching member 3213 and the fastener 3174 to cooperate.

[0070] Example 2:

[0071] This application provides a handheld fan 1000, which includes a fan housing 100, a handheld housing 200, and a connecting arm 300. The connecting arm 300 includes a first part 310 and a second part 320 that are independently disposed therefrom. The first part 310 connects the fan housing 100 and the handheld housing 200 and is integrally formed with the fan housing 100. The second part 320 is connected to the first part 310 and forms a communicating space 301 that connects the handheld housing 200 and the fan housing 100.

[0072] The difference from Embodiment 1 is that in Embodiment 2, the first part 310 is integrally formed with the fan housing 100. With this configuration, it is only necessary to remove the second part 320 from the first part 310 to expose the wiring for inspection and maintenance. This achieves the same effect as in Embodiment 1 where the first part 310 is integrally formed with the handheld housing 200. Further details will not be elaborated here.

[0073] Example 3:

The connecting arm 300 includes a first part 310 and a second part 320 that are independently arranged. The first part 310 connects the fan housing 100 and the handheld housing 200, and the first part 310, the fan housing 100, and the handheld housing 200 are integrally formed. The second part 320 is connected to the first part 310 and forms a communicating space 301 that connects the handheld housing 200 and the fan housing 100.

[0075] The difference from Embodiment 1 is that in Embodiment 3, the first part 310, the fan housing 100, and the handheld housing 200 are integrally formed. With this configuration, it is only necessary to remove the second part 320 from the first part 310 to expose the wiring for inspection and repair, thereby achieving the same effect as the integral formation of the first part 310 and the handheld housing 200 in Embodiment 1. Further details will not be elaborated here.
