The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0094] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0095] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0097] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a highly secure clip-on fan 1000.

[0098] Reference Figures 1 to 7 As shown, the high anti-detachment clip fan 1000 provided according to the embodiment of the present utility model includes a fan head 10, a connecting arm 20, a clip base 30, and a switch lock component 40 for controlling the opening / closing of the clip base 30;

[0099] The fan head 10, the connecting arm 20, and the clamp base 30 are connected in sequence from top to bottom; the switch lock component 40 is provided on the clamp base 30.

[0100] Based on the above, it is clear that this application is mainly used as a high-anti-detachment clip fan 1000 in specific implementation.

[0101] Specifically, when applying this application, install it at the desired location. First, control the opening of the clip base 30 using the provided switch lock component 40. Then, clamp and fix the clip base 30 to a stroller frame, bicycle frame, or tent top support pole, etc. Afterward, control the clip base 30 to remain in a clamped closed state using the switch lock component 40, so that it is stably clamped and fixed at the desired installation location. In this way, this application can be used easily.

[0102] Clearly, the main difference between this application and traditional clip fans lies in the addition of a switch-lock component 40. This alters the traditional clip base 30 structure, which can be easily pried open by hand. The switch-lock component 40 controls the opening and closing of the clip base 30. After clamping and fixing the clip base 30 to a stroller frame, bicycle frame, or tent top support pole, the switch-lock component 40 keeps the clip base 30 in a closed, clamped state, ensuring stable clamping at the desired installation position. As long as the switch-lock component 40 remains stationary, the clip base 30 will not easily open, providing excellent fixation and preventing slippage. This ensures a secure installation, especially when installed on stroller frames, bicycle frames, or tent top support poles, preventing it from easily falling and injuring the user, thus enhancing safety.

[0103] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0104] Furthermore, in specific implementation, in accordance with... Figure 3 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the clamp base 30 includes an upper clamping claw 301, a lower clamping claw 302, and a lever assembly 303;

[0105] The left end of the upper gripper 301 and the left end of the lower gripper 302 are connected through the lever assembly 303; the switch lock member 40 is connected to the lever assembly 303 to control the lever assembly 303 to drive the right end of the upper gripper 301 and the right end of the lower gripper 302 to open in opposite directions or close in opposite directions.

[0106] Therefore, it can be clearly stated that, compared with the clip base 30 used in traditional clip fans, the clip base 30 described in this application does not use a torsion spring structure to drive the upper clamp 301 and the lower clamp 302 to open in opposite directions or close in opposite directions. Instead, it uses the lever principle, and sets the lever assembly 303 to form a lever transmission mechanism to drive the right end of the upper clamp 301 and the right end of the lower clamp 302 to open in opposite directions or close in opposite directions.

[0107] The advantages of this design are as follows: Firstly, the lever principle itself is very easy to operate. When the lever assembly 303 drives the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions or close in opposite directions, the operation is very effortless and can greatly reduce the operator's physical strength. Secondly, as long as the switch lock component 40 is not moved, it will not control the lever assembly 303 to drive the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions or close in opposite directions, so that the right end of the upper jaw 301 and the right end of the lower jaw 302 can be well maintained in the opposite open state or the opposite closed state, making the upper jaw 301 and the lower jaw 302 of this application stable in use.

[0108] Preferably, in this technical solution, the comparison continues. Figure 3 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the switch lock component 40 includes a switch screw 401 and a handle 402 threadedly connected to the left half of the switch screw 401; the lever assembly 303 includes a connecting cover 3031, an upper connecting rod 3032, a lower connecting rod 3033 and a transmission lever 3034.

[0109] The upper jaw 301 has an upper connecting ear 3011 at the left end, and an upper rotating hole 3012 that penetrates its front and rear end faces is opened on the upper part of the upper connecting ear 3011. The upper sleeve hole 3013 that penetrates its front and rear end faces is opened on the lower part of the upper connecting ear 3011.

[0110] Furthermore, the lower jaw 302 has a lower connecting ear 3021 at the left end, and a lower rotating hole 3022 penetrating its front and rear end faces is opened at the lower part of the lower connecting ear 3021, and a lower sleeve hole 3023 penetrating its front and rear end faces is opened at the upper part of the lower connecting ear 3021.

[0111] Based on this, the connecting cover 3031 of this application has a through hole 30311 with an inner diameter larger than the outer diameter of the switch screw 401 and smaller than the outer diameter of the handle 402 in the middle of the left end face, and the right end is formed as a cover opening, which covers the upper connecting ear 3011 and the lower connecting ear 3021; ​​the upper connecting rod 3032 passes through the upper rotating hole 3012, and its front and rear ends are respectively fixed to the upper front part and the upper rear part of the connecting cover 3031, so that the left end of the upper jaw 301 is rotatably connected to the upper part of the connecting cover 3031; the lower connecting rod 3033 passes through the lower rotating hole 3022, and its front and rear ends are respectively fixed to the lower front part and the lower rear part of the connecting cover 3031, so that the left end of the lower jaw 302 is rotatably connected to the lower part of the connecting cover 3031.

[0112] Based on this, the transmission lever 3034 described in this application is inserted into the upper sleeve hole 3013 and the lower sleeve hole 3023 in the front-back direction; the right end of the switch screw 401 passes through the through hole 30311 and is connected to the transmission lever 3034. At this time, the right end face of the handle 402 will abut against the middle of the left end face of the connecting cover 3031 and cover the through hole 30311.

[0113] Therefore, it can be clearly understood that the working principle of the switch lock component 40 described in this application is roughly as follows:

[0114] On the one hand, when the handle 402 is turned to the left, the left part of the switch screw 401 located between the right end face of the handle 402 and the left end face of the connecting cover 3031 will be exposed. At this time, the switch screw 401 can be pushed to the right so that the right end face of the handle 402 is back against the left end face of the connecting cover 3031. In this process, the switch screw 401 can drive the transmission lever 3034 to move to the right, so as to simultaneously drive the lower part of the upper connecting ear 3011 and the upper part of the lower connecting ear 3021 to move to the right. In this way, the right end of the upper jaw 301 and the right end of the lower jaw 302 can be driven to open in opposite directions in the vertical direction.

[0115] On the other hand, when the handle 402 is turned to the right, the switch screw 401 can be pulled to the left, thereby driving the transmission lever 3034 to move to the left, and simultaneously driving the lower part of the upper connecting ear 3011 and the upper part of the lower connecting ear 3021 to move to the left. In this way, the right end of the upper jaw 301 and the right end of the lower jaw 302 can be driven to close in the vertical direction.

[0116] Obviously, for the application of this application, the operation of turning the switch screw 401 to open the right end of the upper jaw 301 and the right end of the lower jaw 302 in opposite directions or close them in opposite directions is very simple, making the operation of this application truly labor-saving.

[0117] Furthermore, as long as the handle 402 is not turned, the switch screw 401 will not move left or right, thus preventing the transmission lever 3034 from moving left or right. Consequently, the right ends of the upper jaw 301 and the lower jaw 302 can be stably and securely maintained in a back-to-back open state or a front-to-back closed state in the vertical direction. In this way, when the upper jaw 301 and the lower jaw 302 are clamped and fixed in the required installation position, they are not easy to loosen or fall off. This makes the application have good anti-loosening performance in actual use, making it safe and reliable.

[0118] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0119] Furthermore, preferably, in this technical solution, it is still in comparison with... Figure 3 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the lever assembly 303 further includes a counter-spring 3035 that is in a compressed state when the right end of the upper jaw 301 and the right end of the lower jaw 302 are closed towards each other;

[0120] The anti-top spring 3035 is sleeved outside the right half of the switch screw 401 and is limited between the left inner wall of the connecting cover 3031 and the transmission lever 3034.

[0121] Thus, when the handle 402 is turned to the left, the reverse force of the counter-rotating spring 3035 drives the switch screw 401 to move automatically to the right along the through hole 30311. This process eliminates the need for the user to push it to the right by hand. When the switch screw 401 moves to the right automatically, it can drive the transmission lever 3034 to move to the right, thereby synchronously driving the lower part of the upper connecting ear 3011 and the upper part of the lower connecting ear 3021 to move to the right. This process can drive the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions in the vertical direction.

[0122] Therefore, by setting the anti-top spring 3035, this application can be made more time-saving and labor-saving in actual operation.

[0123] Of course, in another embodiment, the anti-top spring 3035 can also be replaced with a torsion spring in which both the first torque end and the second torque end are in a compressed state when the right end of the upper jaw 301 and the right end of the lower jaw 302 are closed towards each other. The torsion spring is sleeved on the outside of the transmission lever 3034, so that its first torque end abuts against the bottom wall of the upper connecting rod 3032 to the upper left, and its second torque end abuts against the upper wall of the lower connecting rod 3033 to the lower left.

[0124] Thus, when the handle 402 is turned to the left, the opposing forces of the first and second torsion ends of the torsion spring can drive the switch screw 401 to move automatically to the right along the through hole 30311. This process also eliminates the need for the user to push it to the right by hand. When the switch screw 401 moves automatically to the right, the switch screw 401 can drive the transmission lever 3034 to move to the right, so as to synchronously drive the lower part of the upper connecting ear 3011 and the upper part of the lower connecting ear 3021 to move to the right. This process can also drive the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions in the vertical direction.

[0125] Therefore, in specific implementations of this application, the lever assembly 303 further includes the anti-top spring 3035, which is in a compressed state when the right end of the upper jaw 301 and the right end of the lower jaw 302 are closed towards each other, or the lever assembly 303 further includes the torsion spring, in which both the first torque end and the second torque end are compressed when the right end of the upper jaw 301 and the right end of the lower jaw 302 are closed towards each other. Fixing it in the position described above makes this application more time-saving and labor-saving to use, and also makes the connection between the upper jaw 301 and the lower jaw 302 more stable and less prone to shaking, and makes the clamping stability more stable and less prone to shaking when clamping the object to be clamped.

[0126] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0127] Furthermore, in specific implementation, in accordance with Figure 1 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the lower bottom surface of the upper jaw 301 is arched upward to form a serrated upper clamping portion 3014, the upper end surface of the lower jaw 302 is recessed downward to form a serrated lower clamping portion 3024, and the lower bottom surface of the lower jaw 302 is flat to form a horizontal lifting portion 3025.

[0128] Therefore, it can be clearly stated that:

[0129] On the one hand, when the lower bottom surface of the upper jaw 301 arches upward to form a serrated upper clamping part 3014, and the upper end surface of the lower jaw 302 is recessed downward to form a serrated lower clamping part 3024, the present application can be better clamped and fixed to the outside of the rod-shaped object, making the clamping stability better and less prone to shaking and rotation.

[0130] On the other hand, when the lower bottom surface of the lower gripper 302 is flat to form a horizontal lifting part 3025, the present application can be placed directly on a flat surface such as a table during actual use, making the present application more flexible to use and thus more adaptable.

[0131] In general, the overall structure of this application is very compact, resulting in a small lower gripper 302 and a small area for the horizontal support portion 3025 formed by its lower bottom surface. In this case, as a preferred embodiment, this application extends the lower gripper 302 outward to form an extension portion 3026. For details, please refer to the accompanying drawings of this application specification. Figure 1 and Figure 3 As shown, this increases the area of ​​the bottom surface of the lower gripper 302, making the application more stable when placed directly on a flat surface such as a desktop.

[0132] Furthermore, in this technical solution, we continue to compare... Figure 1 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the grip 402 has a hanging part 4021 for hanging items.

[0133] In this way, after the application is fixed to the required installation position, the hanging part 4021 can be used to hang items that need to be temporarily hung. For example, if the application is fixed to the frame of a stroller, the hanging part 4021 can be used to hang baby bottles, etc., so that the application can be used as a dual-purpose unit. It can be used not only as a clip fan, but also as a clip hook, making its functions more comprehensive and its practicality stronger.

[0134] In a preferred embodiment, the grip 402 is formed into a horizontal T-shaped structure, so that the middle part can constitute the hanging part 4021.

[0135] Furthermore, through the above-mentioned optimized design, the overall effect of this application is even better.

[0136] Secondly, in specific implementation, refer to Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the upper connecting ear 3011 and the lower connecting ear 3021 are each provided with two pieces from front to back;

[0137] The right end of the switch screw 401 is connected to the middle of the transmission lever 3034 and is limited between the two upper connecting ears 3011 and also between the two lower connecting ears 3021.

[0138] Therefore, by setting multiple upper connecting ears 3011 and multiple lower connecting ears 3021, the connection between the upper clamping claw 301 and the lower clamping claw 302 and the connecting cover 3031 is more stable, and the position of the switch screw 401 is more concentrated, making the overall structure of this application more stable.

[0139] Meanwhile, in this technical solution, compared with Figure 3 , Figure 5 and Figure 7 As shown, according to one embodiment of the present invention, the fan head 10 includes a mesh shell 101, a drive motor 102, and an impeller 103;

[0140] The drive motor 102 is fixedly mounted in the mesh housing 101 facing forward, and the impeller 103 is rotatably mounted on the front shaft of the drive motor 102.

[0141] Based on this, according to one embodiment of the present invention, the fan head 10 further includes a control box 104, a main controller 105, and a rechargeable battery 106;

[0142] The mesh shell 101 has a mounting port 1011 at the rear center, and the control box 104 is detachably snapped into the mounting port 1011, with a through opening on its front end face; the main controller 105, the rechargeable battery 106 and the drive motor 102 are all installed in the control box 104, and the rechargeable battery 106 and the drive motor 102 are both connected to the main controller 105, with the front end shaft of the drive motor 102 extending out from the through opening.

[0143] Therefore, it can be clearly stated that the control box 104 described in this application is independently detachable, so as to facilitate the disassembly of the main controller 105, rechargeable battery 106, drive motor 102 and impeller 103 and other structural components for disassembly, maintenance or replacement. This process does not require disassembling the mesh shell 101.

[0144] Furthermore, in specific implementation, in accordance with Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the top of the connecting arm 20 is provided with a U-shaped connector 50, and the left and right sides of the mesh shell 101 are provided with damping shafts 1012 adapted to rotate and connect with the two upper ends of the U-shaped connector 50.

[0145] Therefore, when the U-shaped connector 50 is provided on the top of the connecting arm 20 and the mesh shell 101 is provided with damping shafts 1012 on the left and right sides respectively, which are adapted to be rotatably connected to the two upper ends of the U-shaped connector 50, the connection position can have rotational damping, so that the fan head 10 can be rotated 360 degrees in the front and back direction to the required angle and fixed at the corresponding angle for blowing air, making the fan head 10 very flexible to use.

[0146] Furthermore, in specific implementation, in accordance with Figure 2 and Figure 7 As shown, according to one embodiment of the present invention, the rear end face of the control box 104 is provided with a charging interface 107, a power switch 108 and a power indicator light 109.

[0147] The charging interface 107 is connected to the rechargeable battery 106 via a charging protection circuit 110 connected to the main controller 105; a battery power detection circuit 111 is connected between the rechargeable battery 106 and the main controller 105; the power switch 108 and the power indicator light 109 are both connected to the main controller 105.

[0148] Therefore, by setting the charging interface 107 to be connected to an external power source, the rechargeable battery 106 can be charged intermittently, so that the application can be used uninterruptedly. By operating the power switch 108, the fan head 10 of the application can be turned on and off. By setting the battery power detection circuit 111 and the power indicator light 109, the power indicator light 109 can be used to display the power of the rechargeable battery 106, so that the user can check the power of the rechargeable battery 106 in real time, so that when the power is low, it can be detected in time and charged in time, making the reliability of the application better.

[0149] It should be added that, in specific implementation, comparison should be made with... Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the connecting arm 20 includes an upper connecting arm 201, a middle connecting arm 202 and a lower connecting arm 203;

[0150] The upper connecting arm 201 has a U-shaped connector 50 at its upper end and a slot 2011 at its lower end, with a groove 2012 on the inner wall of the slot 2011. The upper end of the middle connecting arm 202 is adapted to be inserted into the slot 2011, and an elastic buckle 2021 that can be elastically locked into the groove 2012 is provided on its upper outer wall. The lower end of the middle connecting arm 202 is rotatably connected to the upper end of the lower connecting arm 203. The lower end of the lower connecting arm 203 is connected to the clamp base 30.

[0151] Therefore, it can be clearly stated that:

[0152] On the one hand, when the elastic buckle 2021 is disengaged from the slot 2012, the middle connecting arm 202 and the upper connecting arm 201 can be separated. At this time, the upper connecting arm 201 can serve as a handle, allowing the user to hold the upper connecting arm 201 to lift and use the fan head 10 described in this application. This process does not require disassembling the clip base 30.

[0153] On the other hand, when the middle connecting arm 202 is rotated circumferentially, the upper connecting arm 201 and the fan head 10 fixed on its top can be rotated circumferentially to adjust the blowing direction of the fan head 10.

[0154] Therefore, it can be understood that the fan head 10 described in this application can be fixed to the required installation position by the clip base 30 for use. The fan head 10 described in this application can be rotated 360 degrees in the front-back direction to the required angle and fixed at the corresponding angle for blowing air. The fan head 10 described in this application can be disassembled and taken out independently for independent use. The fan head 10 described in this application can also be rotated circumferentially to adjust its blowing direction.

[0155] Therefore, overall, this makes the fan head 10 described in this application very flexible in use.

[0156] It is further necessary to add that, in specific implementation, we should continue to refer to... Figure 3 and Figure 5 As shown, according to one embodiment of the present utility model, the upper end of the lower connecting arm 203 has a downward-facing rotating groove 2031, and a rotating protrusion 2032 is provided on the inner wall of the rotating groove 2031;

[0157] The lower end of the connecting arm 202 is adapted to be inserted into the rotating groove 2031, and a ring of rotating teeth 2022 adapted to mesh with the rotating protrusion 2032 is provided on the outer wall of its lower end.

[0158] Thus, the rotating protrusion 2032 can form rotational damping, so that when the rotating tooth 2022 rotates around it, the rotational position can be adjusted. That is, when the middle connecting arm 202 rotates circumferentially, the rotating tooth 2022 can be rotated to engage with the rotating protrusion 2032 at a local required position, so as to drive the upper connecting arm 201 and the fan head 10 fixed on its top to rotate circumferentially to the required position, so as to adjust the blowing direction of the fan head 10.

[0159] Other embodiments, etc., will not be described here.

[0160] In summary, the high-anti-detachment clip fan 1000 provided in this application, in practical implementation, mainly involves adding the switch-lock component 40 to the traditional clip fan and changing the traditional clip base 30 structure that can be easily pried open by hand. The switch-lock component 40 controls the opening / closing of the clip base 30. After the clip base 30 is clamped and fixed to a stroller frame, bicycle frame, or tent top support pole, the switch-lock component 40 controls the clip base 30 to remain in a clamped closed state, thus stably clamping and fixing it in the desired installation position. At this time, as long as the switch-lock component 40 is not moved, the clip base 30 will not easily open, resulting in good fixation and anti-detachment performance. This makes the application securely installed, especially when installed on a stroller frame, bicycle frame, or tent top support pole, it is not easy to loosen and fall, thus preventing injury to the user and ensuring the safety of the application.

[0161] Furthermore, compared to the clip base 30 used in traditional clip fans, the clip base 30 described in this application does not use a torsion spring structure to drive the upper clamp 301 and the lower clamp 302 to open in opposite directions or close in opposite directions. Instead, it uses the lever principle, and sets the lever assembly 303 to form a lever transmission mechanism to drive the right end of the upper clamp 301 and the right end of the lower clamp 302 to open in opposite directions or close in opposite directions. On the one hand, the lever principle itself is very labor-saving to operate. When the lever assembly 303 drives the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions or close in opposite directions, the operation is very labor-saving and can greatly reduce the physical strength of the operator. On the other hand, as long as the switch lock component 40 is not moved, it will not control the lever assembly 303 to drive the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions or close in opposite directions, so that the right end of the upper jaw 301 and the right end of the lower jaw 302 can be well maintained in the opposite open state or the opposite closed state, making the upper jaw 301 and the lower jaw 302 of this application stable in use.

[0162] Furthermore, in the application of this application, the opening or closing of the right ends of the upper jaw 301 and the lower jaw 302 is achieved by turning the switch screw 401. This operation is very simple and effortless. As long as the handle 402 is not turned, the switch screw 401 will not move left or right, thus preventing the transmission lever 3034 from moving left or right. This ensures that the right ends of the upper jaw 301 and the lower jaw 302 are stably and securely maintained in an open or closed state in the vertical direction. Consequently, when the upper jaw 301 and the lower jaw 302 are clamped and fixed in the desired installation position, they are not easily loosened or fallen off. This makes the application highly resistant to slippage and ensures safety and reliability during actual use.

[0163] Furthermore, when the handle 402 is turned counterclockwise, the reverse force of the counter-rotating spring 3035 drives the switch screw 401 to move automatically to the right along the through hole 30311. This process eliminates the need for the user to push it to the right manually. When the switch screw 401 moves automatically to the right, it can drive the transmission lever 3034 to move to the right, thereby synchronously driving the lower part of the upper connecting ear 3011 and the upper part of the lower connecting ear 3021 to move to the right. This process enables the right end of the upper jaw 301 and the right end of the lower jaw 302 to open in opposite directions in the vertical direction. Therefore, by setting the counter-rotating spring 3035, this application can be more time-saving and labor-saving in actual operation.

[0164] Furthermore, by arching upwards on the lower bottom surface of the upper jaw 301 to form a serrated upper clamping portion 3014, and by recessing downwards on the upper end surface of the lower jaw 302 to form a serrated lower clamping portion 3024, this application can be better clamped and fixed to the rod-shaped object, resulting in better clamping stability and less wobbling or rotation. When the lower bottom surface of the lower jaw 302 is flat, forming a horizontal supporting portion 3025, this application can be directly placed on a flat surface such as a table during actual use, making it more flexible and adaptable to different applications.

[0165] Furthermore, after this application is fixed to the required installation position, the hanging part 4021 can be used to hang items that need to be temporarily hung. For example, if this application is fixed to the frame of a stroller, the hanging part 4021 can be used to hang baby bottles, etc., so that this application can be used as a dual-purpose unit. It can be used not only as a clip fan, but also as a clip hook, making its functions more comprehensive and its practicality stronger.

[0166] Meanwhile, the fan head 10 described in this application can be fixed to the desired installation position by the clamp base 30. The fan head 10 can rotate 360 ​​degrees in the front-to-back direction to the desired angle and be fixed at the corresponding angle for blowing air. The fan head 10 can be independently disassembled and used independently. The fan head 10 can also rotate circumferentially to adjust its blowing direction. Therefore, overall, the fan head 10 described in this application is indeed very flexible in use.

[0167] Furthermore, the high anti-detachment clip fan 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
