The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0035] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the fan clamping device in this embodiment; Figure 2This is a schematic diagram of the first exploded structure of the fan clamping device of this embodiment.

[0036] like Figure 1 and Figure 2 As shown, a clamping fan comprises: a first shell 1, on which an air outlet 11 is provided; a second shell 2, on which an air inlet 21 is provided; a flexible connecting sleeve 3, which connects the first shell 1 and the second shell 2, and the flexible connecting sleeve 3 is communicated with the first shell 1 and the second shell 2 respectively; a fan assembly 4, which is arranged in the first shell 1 and / or the second shell 2; the first shell 1 and the second shell 2 are bent through the flexible connecting sleeve 3 to form a first clamping structure 31.

[0037] In this embodiment, the air outlet 11 is provided at one end of the first housing 1 facing away from the flexible connection sleeve 3. However, the location of the air outlet 11 is not limited thereto, and in some embodiments, the air outlet 11 can be provided on the side of the first housing 1 adjacent to the flexible connection sleeve 3, depending on the specific application scenario.

[0038] The air inlet 21 is provided at one end of the second housing 2 facing away from the flexible connection sleeve 3. However, the location of the air inlet 21 is not limited thereto. Depending on the specific application scenario, in some embodiments, the air inlet 21 can be provided on the side of the second housing 2 adjacent to the flexible connection sleeve 3.

[0039] In some embodiments, the air outlet 11 is provided at one end of the first housing 1 facing away from the flexible connection sleeve 3, and the air inlet 21 is provided at one end of the second housing 2 facing away from the flexible connection sleeve 3. In this case, the air inlet 21 and the air outlet 11 are located on the same side of the clamping fan. When in use, it is only necessary to ensure that there is no shielding on the side where the air outlet 11 and the air inlet 21 are provided, and the fan can be placed in more forms and use scenarios, thereby improving the convenience of use.

[0040] The main bodies of the first shell 1 and the second shell 2 are both constructed as cuboids, and the cross-sectional areas of the first shell 1 and the second shell 2 and one end of the flexible connection sleeve 3 gradually decrease. However, the shapes of the first shell 1 and the second shell 2 are not limited thereto. According to different specific application scenarios, in some embodiments, the shapes of the first shell 1 and the second shell 2 can be configured as (not limited to): columnar, prism-shaped, spherical, cube-shaped, hemispherical, etc.

[0041] In this embodiment, the flexible connecting sleeve 3 can be: an elastic rubber sleeve or a flexible rubber product, or a composite sleeve with a rubber outer skin and a flexible metal tube inside.

[0042] The setting of the flexible connection sleeve 3 can make the distance between the first shell 1 and the second shell 2 adjustable, so as to facilitate the clamping and placement of the first shell 1 and the second shell 2. The U-shaped or C-shaped structure of the flexible connection sleeve 3 can make the clamped fan hang on the user's neck or belt. At the same time, with the split structure of the first shell 1 and the second shell 2, the clamped fan has better connection stability in wearable application scenarios.

[0043] The fan assembly 4 in this embodiment includes: fan blades 42 and a fan motor 41. The fan blades 42 and the fan motor 41 are integrated in a spatial structure reuse manner. Specifically, the fan blades 42 are mounted on the magnetic ring of the fan motor 41. However, the structure of the fan blades 42 and the fan motor 41 is not limited. In some embodiments, the fan blades 42 and the fan motor 41 can be a split structure, that is, the fan blades 42 and the fan motor 41 are connected only by a rotating shaft.

[0044] In some embodiments, the fan assembly 4 further includes: a fan housing 43, in which the fan blades 42 and the fan motor 41 are both disposed. The fan housing 43 encapsulates the fan blades 42 and the fan motor 41 into a standardized accessory.

[0045] In this embodiment, the fan blades 42 are radial fans. However, the structure of the fan blades 42 is not limited thereto. Depending on the specific application scenario, in some embodiments, the fan blades 42 can also be (not limited to) axial flow or mixed flow fans.

[0046] In this embodiment, the fan assembly 4 is disposed in the first housing 1. However, the location of the fan assembly 4 is not limited thereto, and depending on the specific application scenario, in some embodiments, the fan assembly 4 is disposed in the second housing 2, or the fan assembly 4 is disposed in both the first housing 1 and the second housing 2.

[0047] In the above embodiment, the housing of the fan is constructed into a first housing 1 and a second housing 2, and the air outlet 11 and the air inlet 21 are respectively arranged on the first housing 1 and the second housing 2, and the first housing 1 and the second housing 2 are connected by a flexible connecting sleeve 3, so that the first housing 1, the second housing 2 and the flexible connecting sleeve 3 form a first clamping structure 31. The clamping structure composed of the first housing 1, the second housing 2 and the flexible connecting sleeve 3, because the first housing 1 and the second housing 2 are distributed on both sides, makes the weight distribution of the left and right sides of the clamping fan relatively balanced, so that when clamping and fixing, it is not easy to tip over, the blowing direction is relatively fixed, and the blowing effect is good. At the same time, since the air outlet 11 and the air inlet 21 are respectively arranged on the first housing 1 and the second housing 2, this split structure breaks the traditional form of the relative arrangement of the air outlet 11 and the air inlet 21 of the traditional fan, so that the clamping fan can break through the use restriction that the front and rear of the air outlet 11 and the air inlet 21 of the traditional fan are kept unobstructed, the use restriction of the fan is less, and the application scene is wider.

[0048] The clamping fan further includes: a second clamping structure 32 , which is arranged on the surface of the first shell 1 or the second shell 2 , and an opening direction of the second clamping structure 32 is opposite to an opening direction of the first clamping structure 31 .

[0049] The second clamping structure 32 can be a fixedly arranged clamping plate 321. However, the second clamping structure 32 is not limited thereto, and according to different specific application scenarios, in some embodiments, the second clamping structure 32 can be a clamp with a spring.

[0050] Since the opening directions of the first clamping structure 31 and the second clamping structure 32 are opposite, the clamping fan can be clamped in two forms. First, the clamping fan is clamped by the first clamping structure 31; second, the clamping fan is clamped by the second clamping structure 32. The two clamping methods have opposite openings, and in different clamping forms, the directions of the air outlet 11 and the air inlet 21 are opposite. The two clamping structures can meet the needs of different use environments of the clamping fan, expanding the application scenarios of the clamping fan.

[0051] In some embodiments, the second clamping structure 32 includes: a clamping plate 321, one end of the clamping plate 321 is connected to the surface of the first housing 1, the other end of the clamping plate 321 is suspended, and there is a gap between the suspended end of the clamping plate 321 and the surface of the first housing 1. The gap between the suspended end of the clamping plate 321 and the surface of the first housing 1 makes it more convenient for users to clamp and fix the clamped fan and the supported object.

[0052] In some embodiments, one end of the clamping plate 321 is connected to the surface of the first shell 1 , and the other end of the clamping plate 321 is suspended or a bent portion (not marked) of the clamping plate 321 near the other end abuts against the surface of the first shell 1 .

[0053] See also Figure 3 , Figure 3 It is a cross-sectional schematic diagram of clamping a fan in this embodiment.

[0054] like Figure 3 As shown, in some embodiments, the fan assembly 4 includes: a fan housing 43, a fan motor 41 and a fan blade 42, the fan housing 43 is disposed in the first housing 1, the fan motor 41 and the fan blade 42 are disposed in the fan housing 43, the fan motor 41 is connected to the fan housing 43, and the fan blade 42 is connected to the fan motor 41. The fan assembly 4 provided with the fan housing 43 can become a modular accessory, which facilitates the assembly of the fan assembly 4 into the first housing 1.

[0055] In some embodiments, the fan housing 43 can be manufactured and molded integrally with the first housing 1 , that is, the first housing 1 and the fan housing 43 are integrated into one.

[0056] In some embodiments, an air outlet window 435 and a first air inlet window 433 and / or a second air inlet window 434 are provided on the fan housing 43, the air outlet window 435 is connected to the air outlet 11, and the opening direction of the first air inlet window 433 and / or the second air inlet window 434 is perpendicular to the opening direction of the air outlet 11.

[0057] In this embodiment, the fan blades 42 are radial blades, which can vertically reverse the airflow flowing into the fan housing 43 through the first air inlet window 433 and / or the second air inlet window 434, so that the opening direction of the first air inlet window 433 and / or the second air inlet window 434 is perpendicular to the opening direction of the air outlet 11.

[0058] See also Figure 4 and Figure 5 , Figure 4 is an exploded schematic diagram of the first housing and the fan assembly of this embodiment; Figure 5 Schematic diagram of the exploded view of the fan housing of this embodiment.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments, an air inlet window is provided on the fan housing 43 , and the air inlet window is provided on the side wall of the fan housing 43 .

[0060] In some embodiments, the fan housing 43 is provided with two air inlet windows, namely a first air inlet window 433 and a second air inlet window 434. The first air inlet window 433 and the second air inlet window 434 are respectively arranged on the side wall of the fan housing, and the first air inlet window 433 and the second air inlet window 434 are arranged opposite to each other. The arrangement of the double air inlet windows can increase the air intake in the fan housing 43 and improve the air outlet efficiency of the fan assembly 4.

[0061] In this embodiment, the air outlet window 435 and the air outlet 11 are connected to each other. However, the relative positional relationship between the air outlet window 435 and the air outlet 11 is not limited thereto. In some embodiments, the air outlet window 435 and the air outlet 11 are flush with each other. It should be noted that the air outlet window 435 and the air outlet 11 being flush with each other is a special positional relationship in which the air outlet window 435 and the air outlet 11 are connected to each other.

[0062] The first air inlet window 433 and / or the second air inlet window 434 are perpendicular to the direction of the air outlet 11, so that the airflow in the first shell 1 can vertically enter the fan shell 43. Combined with the use of radial fan blades, the air outlet efficiency of the fan assembly 4 can be improved.

[0063] In some embodiments, an air inlet gap 13 is provided between the side of the fan housing 43 on which the first air inlet window 433 and / or the second air inlet window 434 is opened and the inner surface of the first housing 1, so that the first air inlet window 433 and / or the second air inlet window 434 are connected to the air inlet port 21.

[0064] In the fan housing 43, an air inlet gap 13 is provided between the side of the first air inlet window 433 and the inner mark of the corresponding first housing 1. The air inlet gap 13 enables the first air inlet window 433 to be connected with the flexible connecting sleeve 3, and then connected with the air inlet 21 through the flexible connecting sleeve 3.

[0065] An air inlet gap 13 is provided between the side of the second air inlet window 434 and the inner mark of the corresponding first shell 1 , and the air inlet gap 13 enables the second air inlet window 434 to be connected to the flexible connecting sleeve 3 , and then to be connected to the air inlet 21 through the flexible connecting sleeve 3 .

[0066] When the first air inlet window 433 and the second air inlet window 434 are provided at the same time, an air inlet gap 13 is left between the first air inlet window 433 and the second air inlet window 434 and the inner mark of the first shell 1 corresponding thereto, and the two air inlet gaps 13 are connected to the air inlet 21 through the flexible connecting sleeve 3 respectively.

[0067] The setting of the air inlet gap 13 can not only enable the first air inlet window 433 and / or the second air inlet window 434 to be connected to the air inlet 21, but also facilitate the flow of air. At the same time, since the space of the air inlet gap 13 is smaller than the space of the first shell 1, the airflow entering the air inlet gap 13 is equivalent to air compression, which increases the initial velocity of the airflow when entering the fan blades 42. The initial velocity of the airflow at the air inlet position is high, which can increase the energy of the airflow flowing out of the air outlet 11 after the fan blades 42 are reversed. Therefore, this structure can increase the air outlet efficiency of the fan assembly 4, increase the airflow movement speed, and make the blowing effect of the fan assembly 4 better.

[0068] In some embodiments, the clamping fan further includes: an air guide member 5, which has an air outlet window 435 as a gap, is arranged around the fan blades 42, and a partial structure of the air guide member 5 is connected to or overlaps with a partial inner surface of the fan housing 43.

[0069] The air guide member 5 is arranged around the fan blades 42, and can guide the airflow generated when the fan blades 42 rotate. The surrounding arrangement can prevent the airflow from colliding with the protruding position or the recessed position inside the fan housing 43 when the fan blades 42 rotate, thereby reducing the air outlet efficiency of the fan blades 42. This structure can improve the air outlet efficiency of the fan assembly 4. Part of the structure of the air guide member 5 is connected to or overlaps with part of the inner surface of the fan housing 43, making full use of the space in the first housing 1, so that the setting space of the air guide member 5 is wider, and the overlapping positions can also provide support for the air guide member 5, avoiding the air guide member 5 from being arranged without support, causing the air guide member 5 to be easily damaged by external force, or avoiding resonance with the vibration generated by the rotation of the fan blades 42, thereby increasing the vibration amplitude and noise of the fan assembly 4.

[0070] See also Figure 6 , Figure 6 This is a schematic diagram of the first exploded structure of the fan clamping device of this embodiment.

[0071] like Figure 6 As shown, in some embodiments, a storage bin 6 is provided between the first shell 1 and the second shell 2, a connecting slot 12 is provided at one end of the first shell 1 connected to the storage bin 6, the storage bin 6 is connected to the edge of the connecting slot 12, the fan shell 43 is connected to the storage bin 6, and a connecting pillar 63 is also provided between the fan shell 43 and the storage bin 6, so that there is an air inlet gap 13 between the side of the first air inlet window 433 and / or the second air inlet window 434 and the inner surface of the first shell 1.

[0072] The connecting slot 12 opened in the first shell 1 is connected to the storage bin 6 via the edge of the connecting slot 12, so that part of the structure of the storage bin 6 can be extended into the connecting slot 12. Through this clever use of space, the volume of the storage bin 6 leaking out can be reduced, making the overall structure of the clamping fan more simple and compact.

[0073] The fan housing 43 is fixed on the storage bin 6 . Since the storage bin 6 is detachable, the fan housing 43 is fixed on one side of the storage bin 6 to facilitate assembly and disassembly of the fan housing 43 .

[0074] A connecting pillar 63 is also provided between the fan housing 43 and the storage bin 6. The function of the connecting pillar 63 is to provide support between the fan housing 43 and the storage bin 6 to prevent the fan housing 43 and the storage bin 6 from being tightly attached, thereby causing the air inlet gap 13 between the fan housing 43 and the storage bin 6 to be closed.

[0075] Since a connecting slot 12 is provided on one side of the fan housing 43 connected to the storage bin 6 , the side of the storage bin 6 facing the fan housing 43 becomes the inner surface of the first housing 1 , so that an air inlet gap 13 needs to be set between the fan and the storage bin 6 .

[0076] The fan housing 43 is fixed on the storage bin 6, so the side of the fan assembly 4 opposite to the storage bin 6 can be suspended in the air, and a second air inlet window 434 is provided on the suspended side. The suspended structure also provides an air inlet gap 13 between the second air inlet window 434 and the inner surface of the first housing 1.

[0077] The connecting pillar 63 is protruded on the surface of the storage bin 6, and a screw hole (not marked) is opened on the connecting pillar 63. The fan housing 43 is opened with a connecting hole (not marked) at the corresponding position of the connecting pillar 63. The fan housing 43 and the storage bin 6 are connected by screws inserted into the connecting hole and the screw hole.

[0078] In some embodiments, the connection pillars 63 are protrudingly disposed on the surface of the fan housing 43 .

[0079] The connection method between the fan housing 43 and the storage bin 6 is not limited to screw connection. Depending on the specific application scenario, in some embodiments, the connection method between the fan housing 43 and the storage bin 6 is (not limited to): snap-on, welding, gluing, etc.

[0080] The fan housing 43 includes: an upper housing 431 and a lower housing 432, and the air guide member 5 includes: a first air guide component 51 and a second air guide component 52. The first air guide component 51 is arranged in the upper housing 431, and the second air guide component 52 is arranged in the lower housing 432. The first air guide component 51 and the second air guide component 52 are arranged opposite to each other and are assembled with each other.

[0081] The fan housing 43 is manufactured by splitting and splicing, which greatly reduces the manufacturing difficulty of the fan housing 43. The air guide 5 is formed by splicing the first air guide component 51 and the second air guide component 52, which can reduce the difficulty of preparing the air guide 5, and the splicing structure can make the air guide 5 more sealed and have a better air guiding effect.

[0082] The clamping fan further includes: a clamping and fastening mechanism 7 , which is arranged on the storage bin 6 and the second shell 2 , and is used to enhance the clamping force of the first clamping structure 31 .

[0083] The clamping and fastening mechanism 7 can be arranged on the storage compartment 6 and the second shell 2 (not limited to): a magnetic structure, a snap structure, a lock structure, a screw connection structure or Velcro, etc.

[0084] The setting of the clamping and fastening mechanism 7 can increase the clamping strength of the first clamping structure 31, so that the clamping fan is clamped more stably when the first clamping structure 31 is used for clamping, and the air outlet of the clamping fan is more stable and the blowing effect is better.

[0085] The clamping and fastening mechanism 7 includes: a first magnetic attraction component 71 and a second magnetic attraction component 72 . The first magnetic attraction component 71 is arranged on the storage compartment 6 , and the second magnetic attraction component 72 is arranged on the second shell 2 .

[0086] Since the magnetic connection is the most convenient for disassembly and connection, magnetic attraction is selected as the clamping and fastening mechanism 7, which makes it convenient for users to clamp, use and store the clamping fan, improves the stability of the clamping connection and improves the convenience of using the clamping fan.

[0087] The first magnetic attraction component 71 is composed of four magnetic blocks made of magnets or magnetic metals. The second magnetic attraction component 72 is also composed of four magnetic blocks made of magnets or magnetic metals. The four magnetic blocks of the second magnetic attraction component 72 are arranged on the side surface of the second shell 2 facing the storage compartment 6, and the corresponding four magnetic blocks of the first magnetic attraction component 71 are arranged on the surface of the storage compartment 6 facing the second shell 2. The external magnetic blocks maximize the magnetic connection, improve the stability of the magnetic connection, and reduce the risk of the clamped fan falling.

[0088] The number of magnetic blocks constituting the first magnetic component 71 or the second magnetic component 72 is not limited to four. Depending on the specific application scenario, in some embodiments, the number of magnetic blocks constituting the first magnetic component 71 or the second magnetic component 72 can be (not limited to) 1, 2, 3, 5, 6 or more.

[0089] In some embodiments, the second magnetic attraction component 72 is disposed on the inner surface of the side wall of the second housing 2 facing the storage bin 6. The first magnetic attraction component 71 is disposed on the inner surface of the side wall of the storage bin 6 facing the second housing 2. This built-in structure can reduce the damage to the magnetic attraction block during use and extend its service life.

[0090] In some embodiments, the first air guide component 51 is arranged between the fan component 4 and the air outlet window 435 and bulges inward to form a first air guide tongue 511. The second air guide component 52 bulges at a position corresponding to the first air guide tongue 511 to form a second air guide tongue 521. Both sides of the first air guide tongue 511 and the second air guide tongue 521 are recessed inward to form an inner arc surface. The first air guide tongue 511 and the second air guide tongue are arranged on the side pointed by the rotation direction D of the fan blades 42, and the cross-sectional area of ​​the first air guide tongue 511 and the second air guide tongue 521 gradually decreases along the direction of their bulge.

[0091] Since the fan blades 42 are radial blades, during the rotation of the fan blades 42, the airflow blown out from the fan blades 42 has a tendency to tilt along the direction of rotation of the fan blades 42, that is, the movement direction of the blown airflow can be decomposed into: a composite movement along the direction of the air outlet 11 and perpendicular to the direction of the air outlet 11. Therefore, the airflow blown out by the fan blades 42 will be concentrated toward the side pointed by the direction of rotation of the fan blades 42. The first air guide tongue 511 and the second air guide tongue 521 are arranged at this position, so that the tilted airflow can flow out of the air outlet 11 along the direction of the first air guide tongue 511 and the second air guide tongue 521 under the action of the wall attachment effect, thereby improving the directionality of the airflow blown out by the clamping fan. At the same time, since both sides of the first air guide tongue 511 and the second air guide tongue 521 are recessed inward to form an inner arc surface, the inner arc surface close to the fan blade 42 can make the angle between the airflow blowing out of the fan and the first air guide tongue 511 and the second air guide tongue 521 obtuse, increase the collision angle between the airflow and the first air guide tongue 511 and the second air guide tongue 521, reduce the energy loss caused by the collision, and improve the air outlet efficiency of the clamping fan. The other side opposite to the fan blade 42 is also constructed as an inner arc surface, which can guide the outlet direction of the airflow toward the wind direction of the air outlet 11, so that the direction of the airflow blowing out of the air outlet 11 is more concentrated, and the airflow in the dispersed direction is less, so that the effective blowing efficiency of the clamping fan is higher.

[0092] The cross-sectional areas of the first air guide tongue 511 and the second air guide tongue 521 along the direction in which they are raised gradually decrease. Since the amount of air flowing out through the first air guide tongue 511 and the second air guide tongue 521 gradually decreases along the opposite direction of the direction in which the first air guide tongue 511 and the second air guide tongue 521 are raised, the cross-sectional areas of the first air guide tongue 511 and the second air guide tongue 521 along the direction in which they are raised gradually decrease, and conversely, the cross-sectional areas along the opposite direction in which they are raised gradually increase, so that the area occupied by the first air guide tongue 511 and the second air guide tongue 521 becomes larger and larger, and the airflow flowing therethrough is gradually pressurized, thereby ensuring that the airflow at each position of the air outlet 11 and the energy of the blown airflow remain uniform.

[0093] In some embodiments, a wire passing port 522 is provided on the second air guide component 52, and a sealing plate 512 is formed at a position corresponding to the wire passing port 522 and plugged into the wire passing port 522 on the first air guide component 51. Since the fan motor 41 needs to be powered by an external wire, or controlled by the battery 61 and the PCB circuit board 62 of the storage compartment 6, it is necessary to provide a wiring groove on the first air guide component 51 or the second air guide component 52 that is arranged around. By plugging the wiring groove with the sealing plate 512, the air leakage problem of the air guide 5 caused by the large area of ​​the wiring groove can be avoided, thereby maximizing the air guiding efficiency of the air guide 5.

[0094] In some embodiments, an air guide grille 436 is provided at the position of the air outlet window 435, and the fan blades 42 in the fan assembly 4 are radial blades. The cross-sectional area of ​​the air guide grille 436 in the air outlet direction gradually increases along the direction of rotation of the fan blades 42. In this embodiment, when the fan assembly 4 is provided with a fan housing 43, the air guide grille 436 is embedded in the fan housing 43. When the fan assembly 4 is not provided with a fan housing 43, the air guide grille 436 is embedded in the first housing 1.

[0095] Since the fan blades 42 in the fan assembly 4 are radial blades, the airflow needs to be reversed and then blown out during its rotation, that is, the movement direction of the blown airflow can be decomposed into: a composite movement along the direction of the air outlet 11 and perpendicular to the direction of the air outlet 11. This blowing method makes the airflow extend more in the direction of rotation of the fan blades 42, and its movement speed perpendicular to the direction of the air outlet 11 is faster, and it has greater lateral movement energy; on the contrary, the more the airflow extends in the opposite direction of the rotation of the fan blades 42, the greater the energy of the airflow moving in the direction of the air outlet 11, and the smaller the movement energy perpendicular to the direction of the air outlet 11. When the movement energy in the vertical direction is greater, a larger space is required to constrain the airflow so that it moves toward the direction of the air outlet 11, and therefore, it gradually increases along the direction of rotation of the fan blades 42. This structure of the air guide grille 436 improves the ability of the clamping fan to directional air supply, so that the effective blowing capacity of the clamping fan is improved.
