The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0041] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the portable fan in this embodiment; Figure 2 This is an exploded structural diagram of the fan housing 1 in this embodiment.

[0042] like Figure 1 and Figure 2 As shown, a portable fan includes: a fan housing 1; a fan assembly 2, the fan assembly 2 being disposed inside the fan housing 1, and the fan housing 1 having a fan inlet 15 and a fan outlet 16 communicating with the fan assembly 2; the fan housing 1 includes: a first housing 11 and a second housing 12, the first housing 11 being fitted onto the second housing 12.

[0043] In the embodiment, the fan housing 1 comprises a first housing 11 and a second housing 12, and the first housing 11 is sleeved on the second housing 12. The connection between the first housing 11 and the second housing 12 is not limited to interference fit, screw connection, adhesive connection or buckle connection, etc.

[0044] The sleeving mode of the first housing 11 and the second housing 12 is full wrapping or partial wrapping. When the first housing 11 fully wraps the second housing 12, the fan air inlet 15 and the fan air outlet 16 are formed on the first housing 11 and the second housing 12. When the first housing 11 partially wraps the second housing 12, the fan air inlet 15 is formed on the first housing 11 and the second housing 12, and the fan air outlet 16 is formed on the exposed position of the second housing 12 which is not wrapped.

[0045] In some embodiments, the fan housing 1 comprises a first housing 11, a second housing 12 and a third housing 13, wherein the first housing 11 is sleeved on the second housing 12, and the third housing 13 is inserted into the second housing 12. The fan assembly 2 is connected with the third housing 13, and each air inlet penetrates through the first housing 11 and the second housing 12. The fan air inlet 15 is arranged on the first housing 11 and the second housing 12, and the fan air outlet 16 is formed on the third housing 13.

[0046] The fan assembly 2 comprises a fan motor and fan blades. The motor assembly is a three-phase high-speed motor, but the motor assembly is not limited to this. According to different specific application scenarios, in some embodiments, the motor assembly can be (but is not limited to) a single-phase motor or a two-phase motor.

[0047] The fan blades are axial flow blades. In the process of air inlet and air outlet, the axial flow blades do not need to turn the airflow, so there is no need to set a guide structure inside the portable fan, which simplifies the structure inside the portable fan and improves the blowing efficiency of the portable fan.

[0048] In the above embodiment, the fan housing 1 is provided as a first housing 11 and a second housing 12, and the first housing 11 is sleeved on the second housing 12. This connection structure forms a double-layer structure at the sleeving position of the first housing 11 and the second housing 12. The second housing 12 is wrapped by the first housing 11, so that the connection area between the first housing 11 and the second housing 12 is larger and the connection relationship is more stable. At the same time, the double-layer housing structure has stronger anti-falling and protection performance, and can better protect the internal functional devices.

[0049] In some embodiments, the first shell 11 is made of transparent or translucent material. The material of the first shell 11 includes, but is not limited to, polystyrene, polymethyl methacrylate, polycarbonate, polyethylene terephthalate, transparent nylon, AS (acrylonitrile-styrene copolymer) and other plastic transparent materials, tempered glass, quartz, artificial optical crystal, sapphire.

[0050] The first shell 11 is made of transparent or translucent material, which makes the overall appearance of the fan shell 1 transparent, greatly improving the aesthetics of the portable fan.

[0051] The first shell 11 is sleeved on the second shell 12 in a sleeving manner that the first shell 11 is completely sleeved on the second shell 12. However, the sleeving manner of the first shell 11 and the second shell 12 is not limited to this. According to different specific application scenarios, in some embodiments, the first shell 11 can be partially sleeved on the second shell 12 or the first shell 11 is partially hollowed out and completely or partially sleeved on the second shell 12.

[0052] Please refer to Figure 3 , Figure 3 The figure is a structural schematic diagram of the first shell of the embodiment.

[0053] In some embodiments, the inner surface of the first shell 11 and / or the outer surface of the second shell 12 is provided with identification information.

[0054] The identification information includes specific fonts or patterns with a marking effect, such as trademarks, logos, product names, and pictures, gradient layers, decals and other structures with a decorative effect.

[0055] The identification information is provided on the inner surface of the first shell 11, the outer surface of the second shell 12, or the inner surface of the first shell 11 and the outer surface of the second shell 12 by processes such as electroplating, spraying, pasting, painting and the like.

[0056] The identification information is provided on the inner surface of the first shell 11, the outer surface of the second shell 12, or the inner surface of the first shell 11 and the outer surface of the second shell 12. Since the relative positions of the first shell 11 and the second shell 12 do not change, the first shell 11 can protect the identification information from being damaged or worn by external forces during daily use, so that the identification information can be maintained for a long time. At the same time, the first shell 11 is made of transparent or translucent material, so that the user can observe the identification information through the first shell 11, further improving the aesthetics of the portable fan.

[0057] In some embodiments, the first shell 11 or the second shell 12 is provided with a light strip. The light strip is electrically connected with the battery in the portable fan through the second shell 12. The light strip can make the portable fan have the function of lighting. At the same time, the light strip can make the identification information more beautiful and improve the aesthetic degree of the portable fan after emitting light in the night environment.

[0058] In some embodiments, the fan shell 1 further comprises a third shell 13 which is inserted into the second shell 12.

[0059] The connection mode of the third shell 13 and the second shell 12 is not limited to one or a combination of the following connection modes: interference fit, snap connection, screw connection, and adhesive connection.

[0060] The third shell 13 is provided to assemble the functional devices of the portable fan, including but not limited to switches, fan assemblies 2, battery assemblies 3, PCB circuit boards, etc. The third shell 13 is provided to pre-assemble the functional devices in the third shell 13, and then assemble the third shell 13 and the second shell 12. This avoids directly assembling the functional devices in the second shell 12 and reduces the assembly difficulty.

[0061] The third shell 13 can also support the second shell 12 and the first shell 11, so that the fan shell 1 has stronger extrusion resistance and drop resistance. The three-shell assembly structure not only improves the physical resistance of the fan shell 1, but also has the function of improving the aesthetic appearance.

[0062] In some embodiments, the inner surface of the second shell 12 is provided with a first buckle 121, and the outer surface of the third shell 13 is provided with a second buckle 138 which cooperates with the first buckle 121.

[0063] Please refer to Figure 4 and Figure 5 ; Figure 4 for the second shell structure diagram of the present embodiment; Figure 5 for the second shell cross-sectional view of the present embodiment.

[0064] As Figure 4 and Figure 5As shown, the second shell 12 and the third shell 13 are connected by a snap-fit manner, and the first snap-fit part 121 is arranged on the inner surface of the second shell 12, and the second snap-fit part 138 is arranged on the outer surface of the third shell 13. The inner snap-fit connection manner makes the outer surface of the second shell 12 smooth, and the visual aesthetic feeling is improved. When the snap-fit is released, the second shell 12 needs to be deformed to make the first snap-fit part 121 and the second snap-fit part 138 mutually disengage, and the second shell 12 is supported by the third shell 13, so that the deformation is difficult. Therefore, the snap-fit connection manner makes the connection of the second shell 12 and the third shell 13 more compact and firm.

[0065] In some embodiments, the first shell 11 is provided with a first opening 111 at the bottom surface, and the first opening 111 is provided with a bottom cover plate 14, the bottom cover plate 14 is connected with the second shell 12, and the bottom cover plate 14 is in abutment with the first shell 11.

[0066] The connection manner between the second shell 12 and the bottom cover plate 14 is not limited to: snap-fit connection, screw connection, adhesive connection, rivet connection, etc.

[0067] The bottom cover plate 14 is in abutment with the first shell 11, so that the bottom cover plate 14 can provide abutment force for the sleeving of the first shell 11 and the second shell 12, and avoid mutual disengagement between the first shell 11 and the second shell 12. By fixing the first shell 11 through the bottom cover plate 14, connection marks can be avoided on the first shell 11, so that the overall appearance of the portable fan is improved.

[0068] In some embodiments, the first shell 11 covers the corresponding position of the first snap-fit part 121 to limit the deformation space of the first snap-fit part 121.

[0069] The first shell 11 is sleeved on the second shell 12, and the first shell 11 covers the corresponding position of the first snap-fit part 121, and the covering of the first shell 11 can limit the deformation space of the first snap-fit part 121, avoid the disengagement of the first snap-fit part 121 under external force, and make the portable fan more firm and resistant to falling.

[0070] In some embodiments, the bottom cover plate 14 is provided with a third snap-fit part 141, the second shell 12 is provided with a card hole 127 matched with the third snap-fit part 141, and the third snap-fit part 141 is snap-fit connected with the card hole 127 and / or the shell edge 123 of the second shell 12.

[0071] The third fastener 141 is arranged on the bottom cover plate 14, and a card hole 127 matched with the third fastener 141 is arranged on the second shell 12. The third fastener 141 is inserted into the card hole 127 to be connected with the second shell 12. In some embodiments, the second shell 12 is limited by space, and it is inconvenient to arrange the card hole 127. In this case, the third fastener 141 is directly connected with the shell edge 123 of the second shell 12 or the recessed groove of the shell edge 123.

[0072] In some embodiments, the space of the second shell 12 is large at some positions, and the card hole 127 is arranged at these positions. The space of the second shell 12 is insufficient at some positions, and the card hole 127 is not arranged at these positions. Correspondingly, some third fasteners 141 are inserted into the card hole 127 to be connected with the second shell 12, and some third fasteners 141 are directly connected with the shell edge 123 of the second shell 12 or the recessed groove of the shell edge 123. This connection mode makes full use of the space structure of the second shell 12. The card hole 127 can limit the third fastener 141 inserted therein, and the relative rotation between the bottom cover plate 14 and the second shell 12 is avoided. The structure of the fan shell 1 is more compact and stable.

[0073] The third fastener 141 is connected with the second shell 12 by buckling, which facilitates the assembly of the bottom cover plate 14 and improves the assembly efficiency.

[0074] In some embodiments, the second opening 124 is arranged on the second shell 12, the second opening 124 and the first opening 111 are communicated, and the opening area of the second opening 124 is smaller than that of the first opening 111. The area of the first opening 111 is larger than that of the second opening 124, so that the first shell 11 and the second shell 12 are misaligned at the bottom surface. The structure misaligned by the second shell 12 is the shell edge 123 connected with the third fastener 141. The misalignment relationship formed by the area relationship between the first opening 111 and the second opening 124 can not only make the bottom cover plate 14 and the second shell 12 connected by buckling, but also make the bottom cover plate 14 and the first shell 11 naturally connected by abutting. The hierarchical relationship of the space structure is fully utilized, and the purpose of fixing the first shell 11 and the second shell 12 is achieved. The design is ingenious.

[0075] In some embodiments, the first fastener 121 is a plurality of clamping claws 122, and a triangular stable structure is formed between any clamping claw 122 and its two adjacent clamping claws 122. The second fastener 138 is a plurality of clamping grooves 138a, and a triangular stable structure is formed between any clamping groove 138a and its two adjacent clamping grooves 138a.

[0076] The first clamping member 121 includes three clamping claws 122. However, the number of clamping claws 122 of the first clamping member 121 is not limited to three, and in some embodiments, the number of clamping claws 122 can be (but is not limited to) four, five, six, or more, depending on the specific application scenario.

[0077] The second clamping member 138 includes three clamping slots 138a. However, the number of clamping slots 138a of the second clamping member 138 is not limited to three, and in some embodiments, the number of clamping slots 138a can be (but is not limited to) four, five, six, or more, depending on the specific application scenario.

[0078] The clamping claws 122 of the first clamping member 121 and the clamping slots 138a of the second clamping member 138 that is paired with it both form a triangular stable structure, enabling the clamping connection of the first shell 11 and the second shell 12. The stability of the triangular structure improves the connection strength of the first shell 11 and the second shell 12. Not only can it resist the pulling force along the vertical direction of the fan shell 1, but also can resist the impact of the horizontal force in the horizontal direction of the fan shell 1, making the connection of the first shell 11 and the second shell 12 more stable.

[0079] In some embodiments, first and second edge slots 125 and 126 are respectively formed on the two opposite sides of the first and second shells 11 and 12, and at least part of the structure of the third shell 13 is inserted into the first and second edge slots 125 and 126.

[0080] First and second edge slots 125 and 126 are respectively formed on the two opposite sides of the first and second shells 11 and 12, and at least part of the structure of the third shell 13 is inserted into the first and second edge slots 125 and 126. This structure increases the contact area between the first, second, and third shells 11, 12, and 13, making the connection between the third shell 13 and the second shell 12 more stable.

[0081] In some embodiments, a first assembly compartment 133 is provided in the third shell 13, and the fan assembly 2 is arranged in the first assembly compartment 133.

[0082] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic view of the third shell of the present embodiment; Figure 7 is a schematic view of the second perspective structure of the third shell of the present embodiment.

[0083] As Figure 6 and Figure 7As shown, the first assembly bin 133 is arranged in the third shell 13, so that the fan assembly 2 can be independently arranged in the first assembly bin 133. Compared with the conventional motor assembly mode, the independent assembly bin assembly is more stable. At the same time, the first assembly bin 133 is arranged in the third shell 13, which facilitates the assembly of the fan assembly 2.

[0084] In some embodiments, two opposite sides of the third shell 13 extend towards the first shell 11 or the second shell 12 to form a first insertion edge 131 and a second insertion edge 132, which are respectively inserted into the first side slot 125 and the second side slot 126.

[0085] The arrangement of the first insertion edge 131 and the second insertion edge 132 can improve the stability of the connection of the fan shell 1, and the insertion matching can be quickly assembled, thereby improving the assembly efficiency of the fan shell 1. By extending the side inward to form the insertion edge, the connection between the shells can be realized without increasing additional space, thereby improving the compactness of the fan shell 1.

[0086] In some embodiments, the fan assembly 2 is inserted into the first assembly bin 133, and a buffer sleeve 21 is arranged between the fan assembly 2 and the first assembly bin 133.

[0087] The buffer sleeve 21 in the embodiment is made of silica gel material. However, the material of the buffer sleeve 21 is not limited thereto. According to different specific application scenarios, in some embodiments, the buffer sleeve 21 can be made of (not limited to): paper products, cotton and hemp products, and hollow air cushions.

[0088] The arrangement of the buffer sleeve 21 between the fan assembly 2 and the first assembly bin 133 can increase the firmness and stability of the assembly of the fan assembly 2. At the same time, the arrangement of the buffer sleeve 21 can buffer and filter the mechanical vibration generated by the fan assembly 2 during operation, reduce the vibration amplitude, and also reduce the working noise of the fan assembly 2.

[0089] In some embodiments, the first insertion edge 131 and the second insertion edge 132 are provided with an insertion slot 137 at the contact position with the first side slot 125 and the second side slot 126, and the insertion slot 137 is arranged on the first side slot 125 and the second side slot 126.

[0090] Insertion slots 137 are provided on the first insertion edge 131 and the second insertion edge 132, so that when the first insertion edge 131 is connected to the first side groove 125, the insertion slot 137 is inserted into the first side groove 125; when the second insertion edge 132 is connected to the second side groove 126, the insertion slot 137 is inserted into the second side groove 126. This connection method can provide support between the first insertion edge 131 and the second insertion edge 132 and the first housing 11 and the second housing 12, avoiding deformation of the first insertion edge 131 and the second insertion edge 132 into the fan housing 1 when subjected to external forces, making the structure of the fan housing 1 more stable and enhancing its drop resistance.

[0091] In some embodiments, a second assembly compartment 134 is provided on one side of the first assembly compartment 133, and an assembly groove 135 is provided on the side of the first assembly compartment 133 facing the second assembly compartment 134, and a wire is passed through the assembly groove 135.

[0092] The second assembly compartment 134 is used to assemble the battery assembly 3. However, the function of the second assembly compartment 134 is not limited to this. Depending on the specific application scenario, in some embodiments, the second assembly compartment 134 is also used to install other functional components of the portable fan, such as (but not limited to): control buttons, PCB circuit boards, mounting brackets, etc.

[0093] The first assembly compartment 133 has an assembly slot 135 on the side facing the second assembly compartment 134. The assembly slot 135 allows the first assembly compartment 133 to have a certain deformation space, facilitating the assembly of the fan assembly 2. The existence of this deformation space increases the tolerance of the first assembly compartment 133 to dimensional errors of the fan assembly 2, further improving assembly efficiency. Simultaneously, the assembly slot 135 can also be reused, serving as a wire channel, allowing the fan assembly 2 and battery assembly 3 to be connected via wires, fully utilizing the space within the fan housing 1 and simplifying the wiring layout.

[0094] In some embodiments, a button slot 136 is provided on the first insertion edge 131, and a side wall air inlet 151 is provided on the second insertion edge 132.

[0095] To facilitate carrying and holding, the first housing 11 and second housing 12 of the portable fan in this embodiment are constructed in a flat shape with a relatively large length and height but a small width. With this housing structure, assembling control buttons inside the first housing 11 and second housing 12 is quite difficult. The button slot 136 is formed on the extended first insertion edge 131, facilitating the assembly of the control buttons. A side wall air inlet 151 is formed on the second insertion edge 132, and the side wall air inlet 151 is located on the third housing 13, without damaging the first housing 11 and second housing 12, thus ensuring the integrity and aesthetics of the first housing 11 and second housing 12.

[0096] In some embodiments, the length of the first insertion edge 131 and the second insertion edge 132 is greater than the length of the first assembly bin 133.

[0097] The length of the first insertion edge 131 and the second insertion edge 132 is greater than the length of the first assembly bin 133, which makes full use of the dislocation space formed by the long and short structure, so that the fan assembly 2, the control button and other components attached to the second insertion edge 132 can be assembled without affecting each other, improving the assembly efficiency.

[0098] In some embodiments, the fan shell 1 is connected with a clamping structure 4, the clamping structure 4 is arranged outside the first shell 11, and the clamping structure 4 is connected with the third shell 13. The clamping structure 4 is specifically a deformation clamp or a spring clamp.
