[0034] Please refer to Figures 1-3 , Figure 1 It is a first perspective view of the portable fan structure of the present embodiment; Figure 2 It is a second perspective view of the portable fan structure of the present embodiment; Figure 3 It is a partial exploded view of the portable fan of the present embodiment.

[0035] As Figures 1-3 shown, a portable fan, a fan housing 1; a fan assembly, the fan assembly is suspendedly assembled in the fan housing 1; a hand-held part 2, the hand-held part 2 is connected with the fan housing 1; the hand-held part 2 comprises: a front housing 21 and a rear housing 22, the front housing 21 and the rear housing 22 are buckledly connected with each other, the end of the overhanging end of the rear housing 22 extends in the direction of the front housing 21 to form a bearing table 23, and the front housing 21 is connected with the bearing table 23.

[0036] The fan housing 1 in the present embodiment is a cylindrical hollow housing, and the air inlet and the air outlet of the fan housing 1 are oppositely arranged. However, the shape of the fan housing 1 is not limited thereto, and according to different specific application scenarios, in some embodiments, the shape of the fan housing 1 can be (not limited to): oval, spherical or prismatic. In some embodiments, a handle is further assembled on the fan housing 1 for convenient holding. In some embodiments, the portable fan can be used as an independent module, and an expansion interface is arranged on the fan housing 1 for docking a corresponding expansion module.

[0037] In this embodiment, the fan includes an inner shell and an outer shell, and the outer shell is sleeved on the inner shell. However, the structure of the fan shell 1 is not limited to this. Depending on different specific application scenarios, in some embodiments, the structure of the fan shell 1 can be (but not limited to) one of the following: one-piece molding, half-shell splicing, three-shell sleeving, and the like.

[0038] In this embodiment, the material of the fan shell 1 is plastic. The fan shell 1 made of plastic has the advantages of light weight, wear resistance, and corrosion resistance. However, the material of the fan shell 1 is not limited to this. Depending on different specific application scenarios, in some embodiments, the fan shell 1 can be made of metal materials, alloy materials, and the like.

[0039] In this embodiment, the fan shell 1 and the handheld part 2 are manufactured separately. The connection between the fan shell 1 and the handheld part 2 can be one of the following: plug-in connection, clamping connection, screw connection, riveting connection, adhesive connection, welding connection, and the like.

[0040] In some embodiments, the fan shell 1 and the front shell 21 and the rear shell 22 of the handheld part 2 can be prepared by one-piece molding process. Specifically, the fan shell 1 is also spliced by two half shells, one of which is integrally prepared with the front shell 21, and the other of which is integrally prepared with the rear shell 22.

[0041] In this embodiment, the fan motor can be (but not limited to) one of the following: a single-phase motor, a two-phase motor, or a three-phase motor. The fan blades can be axial flow blades or inclined flow blades.

[0042] In this embodiment, two rows of oppositely arranged buckle structures are arranged in the rear shell 22, and two rows of oppositely arranged pawl structures that cooperate with the buckle structures are arranged on the front shell 21. However, the arrangement of the buckle structure and the pawl structure is not limited to this. Depending on different specific application scenarios, in some embodiments, the buckle structure is arranged on the front shell 21, and the pawl structure is arranged on the rear shell 22; or the buckle structure and the pawl structure are alternately arranged on the front shell 21 and the rear shell 22.

[0043] In this embodiment, the bearing table 23 is arranged on the rear shell 22. However, the arrangement of the bearing table 23 is not limited to this. Depending on different specific application scenarios, in some embodiments, the bearing table 23 can be arranged on the front shell 21, in which case the corresponding structures of the front shell 21 and the rear shell 22 are arranged interchangeably.

[0044] In the above embodiment, the end of the rear shell 22 that is suspended extends towards the front shell 21 to form a bearing platform 23, and the front shell 21 is connected to the bearing platform 23. This design enables the battery to be more stably fixed on the bearing platform 23, avoiding the problem of unstable installation caused by exposure of the battery during the traditional half-shell splicing process, making the assembly of the portable fan more convenient and efficient. At the same time, due to the provision of the bearing platform 23, the rear shell 22 can be placed vertically on the desktop, even after the battery is assembled, the rear shell 22 can still be placed vertically on the desktop without falling. The vertically placed rear shell 22 and battery make it more convenient to assemble, hold and take, thereby further improving the assembly efficiency of the portable fan.

[0045] In some embodiments, the handheld part 2 further comprises a battery assembly 4, a first support 3 is provided between the battery assembly 4 and the bearing platform 23, one end of the first support 3 is arranged in the bearing platform 23, and the other end of the first support 3 abuts against the battery assembly 4.

[0046] Please refer to Figure 4 , Figure 4 for the schematic diagram of the rear shell structure of the present embodiment.

[0047] As Figure 4 shown, the upper surface of the bearing platform 23 is recessed to form a storage groove, and one end of the first support 3 is placed in the storage groove. The other end of the first support 3 protrudes above the bearing platform 23 and abuts against the battery assembly 4, so that the assembly of the battery assembly 4 is more compact.

[0048] In the present embodiment, the battery assembly 4 is a power supply assembly composed of one or more rechargeable batteries. However, the composition of the battery assembly 4 is not limited to this, and in some embodiments, the battery assembly 4 can be a disposable battery according to different specific application programs.

[0049] One end of the first support 3 is fixed inside the bearing platform 23, and the other end directly abuts against the battery assembly 4, further enhancing the stability of the battery assembly 4. This design can effectively prevent the battery assembly 4 from tilting or falling off due to external forces during assembly or use, significantly improving the reliability and safety of the product.

[0050] In this embodiment, the first support 3 is a hard plastic, metal or alloy part. However, the material of the first support 3 is not limited thereto, and in some embodiments, the first support 3 can be made of a cushioning material such as (but not limited to) rubber, silicone, fabric or paper. The design of the first support 3 has a certain elasticity or cushioning ability, which can adapt to the position deviation of the battery assembly 4 caused by manufacturing tolerance or assembly error to a certain extent. This design not only improves the fault tolerance of assembly, but also reduces the risk of assembly failure caused by size mismatch.

[0051] Please refer to Figure 5 , Figure 5 for the schematic diagram of the front shell structure of this embodiment.

[0052] As shown in Figure 5 , in some embodiments, the first support 3 is provided with an arc-shaped guide groove 31 at one end corresponding to the rear shell 22, and the rear shell 22 is provided with a rope passing hole 223 at a position corresponding to the arc-shaped guide groove 31.

[0053] The design of the arc-shaped guide groove 31 provides a good guide path for the hanging rope, which can effectively reduce the resistance and friction of the hanging rope during the passing-in process, so that the end of the hanging rope can pass through the two rope passing holes 223 more smoothly. This design significantly improves the assembly efficiency of the hanging rope and reduces the time and effort of manual operation. At the same time, in traditional design, if a rope passing hole 223 with arc-shaped guide function is directly provided on the shell, a complex mold or processing technology is usually required, which not only increases the manufacturing cost, but also may cause the strength of the shell structure to decrease. The present solution cleverly avoids this problem by separately providing the arc-shaped guide groove 31 and the rope passing hole 223 on the first support 3 and the rear shell 22. This separated design not only reduces the processing complexity of the shell, but also improves the manufacturing efficiency and yield.

[0054] Please refer to Figure 6 , Figure 6 for the schematic diagram of the first support structure of this embodiment.

[0055] As shown in Figure 6 , in some embodiments, the first support 3 is provided with a sound collecting cavity 32, and the sound collecting cavity 32 is provided with mutually interlaced isolation fences 33 longitudinally and transversely.

[0056] In this embodiment, the sound collecting cavity 32 on the first support 3 is provided on the side surface facing the battery assembly 4. However, the position of the sound collecting cavity 32 is not limited thereto, and in some embodiments, the sound collecting cavity 32 is provided on the side surface facing the bearing table 23. Alternatively, sound collecting cavities 32 are provided on both sides facing the battery assembly 4 and the bearing table 23.

[0057] The design of the sound absorption cavity 32 can effectively absorb sound wave energy and reduce noise generated by the fan motor and fan blades during operation. After the sound wave enters the sound absorption cavity 32, it is reflected and absorbed multiple times within the cavity, thereby weakening the propagation intensity of the sound wave and ultimately achieving the purpose of noise reduction. The arrangement of the isolation fence 33 further enhances the sound absorption effect of the sound absorption cavity 32. The crisscross fence structure can divide the sound wave into multiple small areas and further weaken the energy of the sound wave through multiple reflections and diffusion, significantly improving the overall noise reduction effect. At the same time, the sound absorption cavity 32 not only absorbs sound wave energy but also effectively alleviates the vibration generated during device operation. When the internal components of the portable fan vibrate, the air molecules in the sound absorption cavity 32 will compress and expand due to the vibration, thereby consuming part of the vibration energy and reducing the vibration amplitude. The arrangement of the isolation fence 33 further enhances the shock absorption capacity of the sound absorption cavity 32. The crisscross structure between the fences can limit the propagation path of the vibration and further consume vibration energy through air resistance and friction, thereby significantly reducing the overall vibration amplitude of the device.

[0058] In some embodiments, in order to fix the first support 3, a plurality of positioning columns 233 are arranged on the bearing table 23, and a plurality of positioning holes 34 adapted to the positioning columns 233 are arranged on the first support 3 at the position of the sound absorption cavity 32. The arrangement of the positioning holes 34 not only makes the first support 3 more stable, but also increases the reflection and diffusion effect of sound waves and vibrations, improving the noise reduction and shock resistance.

[0059] In some embodiments, a first clamping groove 231 is arranged on the bearing table 23, and a clamping arc 211 matched with the first clamping groove 231 is arranged on the inner surface of the front shell 21, and the clamping positions of the first clamping groove 231 and the clamping arc 211 are staggered with the clamping positions of the front shell 21 and the rear shell 22.

[0060] In traditional shell clamping designs, the clamping points are usually concentrated on the same straight line, which is easy to cause stress concentration at the connection position due to external force, thereby increasing the risk of shell separation. However, the present scheme forms a multiple clamping structure by staggering the clamping positions of the first clamping groove 231 and the clamping arc 211 with the conventional clamping positions of the front shell 21 and the rear shell 22. This design makes the shell connection points distributed in different planes, significantly improving the stability of the overall connection. The staggered clamping design makes the external force more evenly distributed at the shell connection, avoiding the connection failure problem caused by excessive local stress. At the same time, when external force acts on the conventional clamping positions of the front shell 21 and the rear shell 22, the staggered first clamping groove 231 and the clamping arc 211 will further lock the connection state through internal stress, making it difficult for the front shell 21 or the rear shell 22 to be lifted. This design makes it difficult for the front shell 21 and the rear shell 22 to separate when stressed, thereby significantly improving the anti-separation ability of the connection.

[0061] In some embodiments, the front shell 21 extends in the direction of the rear shell 22 above the clamping arc 211 to form a second support 212, and the support column 232 is arranged below the second support 212, and the second support 212 is located between the support column 232 and the battery assembly 4.

[0062] In this embodiment, the end section area of the battery assembly 4 is larger than the section area of the first support 3. Therefore, after the battery assembly 4 is in contact with the first support 3, part of the battery assembly 4 is exposed. In order to prevent the exposed battery assembly 4 from being unstable or easily shaken due to lack of support, the second support 212 is arranged on the front shell 21.

[0063] The second support 212 extends from the front shell 21 to the direction of the rear shell 22 and cooperates with the support column 232 to optimize the space layout inside the shell. This design not only saves space, but also makes the overall structure more compact and reasonable.

[0064] In some embodiments, the second support 212 and the first support 3 abut each other. After the second support 212 and the first support 3 abut each other, the first support 3 is effectively limited in the horizontal direction, which can prevent the first support 3 from being laterally displaced or shaken due to external force or vibration. The first support 3 is usually used to fix the battery assembly 4, and its stability directly affects the installation stability of the battery assembly 4. Through the limiting action of the second support 212, the loosening or abnormal function of the battery assembly 4 caused by the shaking of the first support 3 can be effectively avoided. At the same time, the relative positional relationship between the rope passing hole 223 and the arc-shaped guide groove 31 can be kept stable.

[0065] In some embodiments, the upper surface of the first support 3 and the highest point of the second support 212 in the vertical direction are flush with each other. The upper surface of the first support surface and the highest point of the second support surface are flush, which can make the support of the first support 3 and the second support 212 to the battery assembly 4 located on the same horizontal plane, and the support to the battery assembly 4 is more stable.

[0066] In some embodiments, the second support 212 and the support column 232 are both wedge-shaped. The wedge-shaped structure allows the second support 212 to be easily inserted between the battery assembly 4 and the support column 232. The narrow design of the tip reduces the resistance during insertion, making assembly more convenient and fast. The wedge-shaped structure will gradually widen after insertion, thereby forming a stable support between the battery assembly 4 and the support column 232. This design can effectively prevent the battery assembly 4 from shaking or falling off due to external force.

[0067] It should be noted that the shape of the second support 212 is not limited thereto, and according to different specific application scenarios, in some embodiments, the second support 212 can be (but is not limited to) a circular column, a prism, or an elliptical structure.

[0068] Please refer to Figure 7 , Figure 7 The schematic diagram of the fan shell structure of the present embodiment is shown.

[0069] As Figure 7 shown, in some embodiments, the fan shell 1 extends to form a fixing seat 11 facing the handheld part 2, the fixing seat 11 is inserted into the handheld part 2, the fixing seat 11 is respectively provided with a first clamping rib 111 and a second clamping rib 112, the first clamping rib 111 and the second clamping rib 112 are spaced apart along the extension direction of the fixing seat 11, and the handheld part 2 is respectively clamped and connected with the first clamping rib 111 and the second clamping rib 112.

[0070] By providing the first clamping rib 111 and the second clamping rib 112 on the fixing seat 11 and respectively clamping and connecting with the handheld part 2, a double locking structure is formed. This design can effectively prevent the connection from loosening due to single-point clamping failure, and significantly improve the stability and reliability of the connection. The two clamping ribs are spaced apart along the extension direction of the fixing seat 11, so that the force is more evenly distributed. When external force acts on the fan shell 1 or the handheld part 2, the force can be borne by the two clamping points together, avoiding structural failure caused by excessive force on a single point. The double clamping design forms a double support structure between the fixing seat 11 and the handheld part 2. This design can effectively absorb and buffer the energy transmission caused by external force or vibration, reducing the relative movement between the shell and the handheld part 2.

[0071] The first clamping rib 111 in the present embodiment includes two rib bodies respectively on the left and right sides of the fixing seat 11. However, the structure of the first clamping rib 111 is not limited thereto, and in some embodiments, the first clamping rib 111 is a single-sided rib body, and the first clamping rib 111 and the second clamping rib 112 are disposed on the left and right sides of the fixing seat 11. Alternatively, the first clamping rib 111 is a ring structure arranged around the surface of the fixing seat 11.

[0072] The second clamping rib 112 in the present embodiment includes two rib bodies respectively on the left and right sides of the fixing seat 11. However, the structure of the second clamping rib 112 is not limited thereto, and in some embodiments, the second clamping rib 112 is a single-sided rib body, and the second clamping rib 112 and the second clamping rib 112 are disposed on the left and right sides of the fixing seat 11. Alternatively, the second clamping rib 112 is a ring structure arranged around the surface of the fixing seat 11.

[0073] In some embodiments, the hand-held part 2 is provided with a clamping stop 221 above the first clamping ridge 111, and the upper surface of the first clamping ridge 111 abuts the lower surface of the clamping stop 221. The design of the clamping stop 221 can effectively prevent the first clamping ridge 111 from moving upward under force, thereby preventing the connection from failing due to the loosening of the clamping point.

[0074] The hand-held part 2 is provided with a second clamping groove 222 at a position corresponding to the second clamping ridge 112, and the second clamping ridge 112 is arranged in the second clamping groove 222. The mutual abutment of the first clamping ridge 111 and the clamping stop 221 and the cooperation of the second clamping ridge 112 and the second clamping groove 222 form a double locking structure. This design can effectively prevent the connection from loosening due to the failure of a single clamping, significantly improving the stability and reliability of the connection. The different clamping modes of the first clamping ridge 111 and the second clamping ridge 112, as well as the positioning function of the clamping groove, can also limit the second clamping ridge 112 upward and downward. Since the connection mode of the fixing seat 11 and the hand-held part 2 is mainly due to the outward pulling force rather than the inward pushing force, the mutual clamping of the first clamping ridge 111 and the clamping stop 221 enhances the resistance to outward pulling force.

[0075] In some embodiments, the second clamping groove 222 includes a first clamping edge 222a and a second clamping edge 222b, the width of the first clamping edge 222a is smaller than the width of the second clamping edge 222b, and the first clamping edge 222a is located on the side of the second clamping ridge 112 close to the first clamping ridge 111, and the second clamping edge 222b is located on the side of the second clamping ridge 112 away from the first clamping ridge 111. Since the width of the first clamping edge 222a is narrower, it plays a good guiding role during assembly. When the second clamping ridge 112 enters the second clamping groove 222, the narrower first clamping edge 222a can help alignment, ensuring that the second clamping ridge 112 is inserted along the correct path, reducing the occurrence of assembly errors. Assembly personnel or automated equipment can more quickly and accurately insert the second clamping ridge 112 into the second clamping groove 222, thereby simplifying the assembly process and improving production efficiency. The second clamping edge 222b has a wider width, providing the second clamping ridge 112 with a larger contact area and stronger support force, and also enhancing the locking effect of the connection to prevent loosening due to external force.

[0076] It should be noted that any of the embodiments in the present embodiment can be independently implemented, or implemented in combination with one or more other embodiments. When combined, the combination manner should not be limited to the combination manner listed in the present embodiment.
