Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a portable clip-on fan. Background Technology

[0002] In daily life and outdoor activities, the demand for personal cooling devices is increasing, especially in hot summers or high-temperature environments. Portable fans are favored because they can provide instant cooling. Although traditional handheld fans can meet certain cooling needs, they require users to hold them continuously during use, which is extremely inconvenient in some scenarios such as outdoor sports and work operations, and restricts the user's freedom of movement.

[0003] To address this issue, various clip-on fan designs have gradually emerged on the market. These fans are typically fixed to locations such as parasol poles, strollers, and desk edges using clip structures, enabling hands-free use and greatly improving convenience and flexibility. However, existing clip-on fans still have some design shortcomings. Assembly is complex; some clip-on fans have complex installation structures that require screws or pins for fixing, which not only increases production costs but also makes it inconvenient for users to assemble or disassemble themselves, especially in scenarios requiring frequent disassembly and reassembly. The complex assembly process is particularly prominent in these scenarios. The clamping is unstable; some clip-on fans have poorly designed clamping structures that cause them to slip easily when clamping cylindrical objects such as parasol poles, affecting their performance. Furthermore, some clip-on fans have overly simplistic designs, only suitable for clamping objects of specific sizes, and cannot broadly adapt to the needs of different usage scenarios.

[0004] Therefore, a portable clip-on fan is needed to improve the above problems. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a portable clip-on fan, which aims to address the problems of complex assembly and unstable clamping in existing clip-on fans.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable clip-on fan includes a mounting base, a clamping seat disposed at the bottom of the mounting base, a mounting frame fixedly connected to the top of the mounting base, and a fan rotatably connected inside the mounting frame. A connecting structure is provided between the mounting base and the clamping seat, through which the clamping seat can rotate relative to the mounting base. A torsion spring is also installed between the mounting base and the clamping seat. A silicone pad is fixedly adhered to one end of each of the mounting base and the clamping seat on opposite sides.

[0008] The connection structure includes two lower outer connecting blocks fixedly connected to the top of the clamping seat, two lower inner connecting blocks fixedly connected to the top of the clamping seat and located between the two lower outer connecting blocks, and two upper connecting blocks fixedly connected to the bottom of the mounting seat. The lower outer connecting blocks and the adjacent lower inner connecting blocks form a mounting cavity. When the mounting seat and the clamping seat are assembled, the two upper connecting blocks are aligned and inserted into the two mounting cavities. The lower inner connecting blocks are provided with mounting holes, and the inner side of the upper connecting blocks is fixedly connected with a rotating protrusion inserted into the mounting hole.

[0009] Preferably, the lower inner connecting block has a first guide slope at its top end near the lower outer connecting block, and the bottom end of the rotating protrusion has a second guide slope that slides in cooperation with the first guide slope.

[0010] Preferably, a reinforcing rib is fixedly connected between the side of the lower inner connecting block away from the lower outer connecting block and the clamping seat.

[0011] Preferably, a limiting block is fixedly connected to the top two sides of the clamping seat, and a limiting groove is provided at the bottom of the mounting seat corresponding to the limiting block to accommodate the limiting block. The top of the limiting block is arc-shaped, and the limiting groove is adapted to the shape of the limiting block.

[0012] Preferably, a torsion spring positioning block is fixedly connected to the top of the clamping seat, and the torsion spring is positioned on the outside of the torsion spring positioning block.

[0013] Preferably, the bottom of the mounting base and the top of the clamping base are provided with corresponding arc-shaped clamping openings.

[0014] Preferably, the outer surface of the silicone pad has a plurality of anti-slip protrusions at the arc-shaped clamping opening, and the outer surface of the silicone pad has anti-slip grooves evenly formed on both sides of the anti-slip protrusions.

[0015] Preferably, the bottom of the mounting base has an angled opening at the end away from the silicone pad.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through its connection structure, allows for easy assembly of the mounting base and clamping base. The upper connecting block of the mounting base is aligned and inserted into the mounting cavity formed between the lower outer connecting block and the lower inner connecting block. The rotating protrusion slides against the lower inner connecting block via a second guide slope and a first guide slope, providing guidance for the assembly. This allows the rotating protrusion to be inserted into the mounting hole, completing the assembly of the mounting base and clamping base. The assembly operation is simple and convenient, reducing the need for traditional screw and pin fixing.

[0018] 2. This utility model can be used to clamp onto the shaft of a parasol or similar cylindrical object by means of an arc-shaped clamping opening, so that when using a parasol in summer, there is no need to hold a fan, which improves the convenience of use. The silicone pad can protect the clamped object on the one hand, and increase the friction to improve the clamping stability on the other hand. Furthermore, the anti-slip protrusions and anti-slip grooves can help to stabilize the clamping. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-4This embodiment provides a portable clip-on fan, including a mounting base 1, a clamping seat 4 disposed at the bottom of the mounting base 1, a mounting bracket 2 fixedly connected to the top of the mounting base 1, and a fan 3 rotatably connected inside the mounting bracket 2. The mounting base 1 houses a battery and a control motherboard. The outer side of the mounting base 1 has a switch for controlling the fan 3 to turn on, off, and adjust its speed, as well as a charging interface for charging the battery. This is prior art and will not be described in detail here. A connecting structure is provided between the mounting base 1 and the clamping seat 4, allowing the clamping seat 4 to rotate relative to the mounting base 1. A torsion spring 5 is also installed between the mounting base 1 and the clamping base 4. A silicone pad 12 is fixedly glued to one end of the mounting base 1 and the clamping base 4 on opposite sides. The bottom end of the mounting base 1 away from the silicone pad 12 has a bevel 101. When the portable clip fan is in use, by pressing the end of the mounting base 1 with the bevel 101 toward the clamping base 4, the clamping opening of the mounting base 1 and the clamping base 4, i.e. the end with the silicone pad 12, is opened. After clamping onto an object, the pressed mounting base 1 and the clamping base 4 are released, and the clamping ends of the mounting base 1 and the clamping base 4 are closed under the action of the torsion spring 5. The operation is convenient.

[0026] In this embodiment, the inclination angle between the bevel 101 and the bottom surface of the mounting base 1 is 25°-35°. When the clamping openings of the mounting base 1 and the clamping base 4 are open, the maximum angle is when the bevel 101 of the mounting base 1 is close to the clamping base 4. This is used to limit the maximum opening angle of the clamping openings of the mounting base 1 and the clamping base 4, so as to avoid the opening angle being too large, which would cause the connection between the mounting base 1 and the clamping base 4 to crack.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the connecting structure includes two lower outer connecting blocks 8 fixedly connected to the top of the clamping base 4, two lower inner connecting blocks 9 fixedly connected to the top of the clamping base 4 and located between the two lower outer connecting blocks 8, and two upper connecting blocks 7 fixedly connected to the bottom of the mounting base 1. A mounting cavity is formed between the lower outer connecting blocks 8 and the adjacent lower inner connecting blocks 9. When the mounting base 1 and the clamping base 4 are assembled, the two upper connecting blocks 7 are aligned and inserted into the two mounting cavities. Mounting holes 902 are provided on the lower inner connecting blocks 9, and insertion sockets are fixedly connected to the inner side of the upper connecting blocks 7. During assembly, the rotating protrusion 701 inside the mounting hole 902 is inserted into the mounting cavity formed between the lower outer connecting block 8 and the lower inner connecting block 9 by aligning the upper connecting block 7 of the mounting base 1 with the mounting cavity formed between the lower outer connecting block 8 and the lower inner connecting block 9, and the mounting protrusion 701 is inserted into the mounting hole 902 by rotating it, thus completing the assembly of the mounting base 1 and the clamping base 4. Furthermore, when pressing the mounting base 1 and the clamping base 4, the rotating protrusion 701 rotates within the mounting hole 902, thus achieving a rotatable connection between the mounting base 1 and the clamping base 4. The assembly operation is simple and convenient, reducing the need for traditional screw fixing and pin fixing.

[0028] In this embodiment, as Figure 3and Figure 4 As shown, the lower inner connecting block 9 has a first guide slope 901 at its top end near the lower outer connecting block 8, and the bottom end of the rotating protrusion 701 has a second guide slope that slides in cooperation with the first guide slope 901. When the mounting base 1 and the clamping base 4 are assembled, the rotating protrusion 701 and the lower inner connecting block 9 slide in cooperation with the second guide slope and the first guide slope 901, which provides guidance for the assembly of the two and improves the ease of assembly.

[0029] In this embodiment, as Figure 4 As shown, a reinforcing rib 903 is fixedly connected between the side of the lower inner connecting block 9 away from the lower outer connecting block 8 and the clamping seat 4. The structural strength of the lower inner connecting block 9 is improved by the reinforcing rib 903.

[0030] In this embodiment, as Figure 2 As shown, limit blocks 10 are fixedly connected to the top two sides of the clamping seat 4. The bottom of the mounting seat 1 is provided with a limit groove to accommodate the limit blocks 10. The top of the limit blocks 10 is arc-shaped. The limit groove is adapted to the shape of the limit blocks 10. With the limit blocks 10 and the limit groove, when the mounting seat 1 and the clamping seat 4 rotate through the connecting structure, the limit blocks 10 rotate synchronously in the limit groove. This can provide stable support for the side of the connection between the clamping seat 4 and the mounting seat 1, reduce the stress received at the connection structure, and improve the service life.

[0031] In this embodiment, as Figure 2 As shown, a torsion spring positioning block 6 is fixedly connected to the top of the clamping base 4. The torsion spring 5 is positioned on the outside of the torsion spring positioning block 6. The torsion spring positioning block 6 is used to limit the position of the torsion spring 5 and prevent the position of the torsion spring 5 from shifting, which would affect the performance.

[0032] In this embodiment, as Figure 2 As shown, the bottom of the mounting base 1 and the top of the clamping base 4 are provided with corresponding arc-shaped clamping openings 11. The arc-shaped clamping openings 11 can be used to clamp onto the umbrella pole of a parasol or similar cylindrical objects, so that when using a parasol in summer, there is no need to hold the fan, improving the convenience of use. The outer surface of the silicone pad 12 is provided with several anti-slip protrusions 1202 at the arc-shaped clamping openings 11. The outer surface of the silicone pad 12 is provided with anti-slip grooves 1201 evenly distributed on both sides of the anti-slip protrusions 1202. The silicone pad 12 can provide protection for the clamped object and increase friction to improve the clamping stability. The anti-slip protrusions 1202 can improve the clamping stability on the umbrella pole of a parasol and similar cylindrical objects, and the anti-slip grooves 1201 can improve the clamping stability between the silicone pad 12 and the clamped object.

[0033] In this embodiment, the rotating protrusion 701, the upper connecting block 7 and the mounting base 1 are integrally injection molded, and the lower outer connecting block 8, the lower inner connecting block 9, the reinforcing rib 903, the limiting block 10, the torsion spring positioning block 6 and the clamping base 4 are integrally injection molded.

[0034] In this embodiment, the overall width of the upper connecting block 7 and the rotating protrusion 701 is 3.59 mm, the distance between the lower outer connecting block 8 and the lower inner connecting block 9 is 2.71 mm, the inclination angle of the second guide slope at the bottom of the rotating protrusion 701 is 156.2°, the height of the mounting hole 902 is 8 mm, the height of the reinforcing rib 903 is 6.7 mm, and the contact length between the mounting surface of the top of the rotating protrusion 701 and the mounting hole 902 is 1.5 mm. The upper connecting block 7 with a width of 3.59 mm and the rotating protrusion 701 are connected. 01 Insert into the 2.71 mounting cavity. Under the condition of easy insertion and without deforming the support bone, guided by the second guide slope of 156.2°, assemble the upper connecting block 7, the rotating protrusion 701, the lower outer connecting block 8, and the lower inner connecting block 9. By the height difference between the reinforcing rib 903 and the mounting hole 902, the reverse insertion force and the elasticity of the support bone are achieved. Under the action of the 1.5mm mounting platform surface tension, it can be ensured that the assembly is good and the support bone will not be stretched open and deformed. It also prevents the mounting platform from springing open under the action of the torsion spring.

[0035] The anti-slip protrusions 1202 have a diameter of 1.5mm, a height of 0.56mm, and a spacing of 2.8mm between adjacent protrusions. Under the force of the silicone with a hardness of 45 degrees, they effectively clamp the umbrella shaft. The 0.56mm height compression and 2.8mm spacing have been repeatedly verified, and this height and spacing dimension provides a more powerful clamping effect on the umbrella shaft. The size and height of these protrusions on the silicone pad enhance the aesthetics of the clip fan. The protrusions effectively prevent slippage when clamping the umbrella shaft. This type of dotted protrusion structure provides better individual gripping of the umbrella shaft and friction between each protrusion than conventional linear anti-slip pads, resulting in a more stable clamping effect than conventional EVA surfaces and linear anti-slip structures.

[0036] Working principle: During assembly, the torsion spring 5 is positioned outside the torsion spring positioning block 6 to determine its installation position. Then, the upper connecting block 7 of the mounting base 1 is inserted into the mounting cavity formed between the lower outer connecting block 8 and the lower inner connecting block 9. The rotating protrusion 701 slides with the lower inner connecting block 9 through the cooperation of the second guide slope and the first guide slope 901, providing guidance for their assembly. This allows the rotating protrusion 701 to be inserted into the mounting hole 902, completing the assembly of the mounting base 1 and the clamping base 4. When using this portable clip fan, pressing the end of the mounting base 1 with the bevel 101 toward the clamping base 4 will engage the mounting base 1. The clamping port of the clamping seat 4, which has a silicone pad 12, is open. After clamping onto an object, the pressing of the mounting seat 1 and the clamping seat 4 is released. The assembly operation is simple and convenient, reducing the need for traditional screw fixing and pin fixing. Under the action of the torsion spring 5, the clamping ends of the mounting seat 1 and the clamping seat 4 are closed. The arc-shaped clamping port 11 can be used to clamp onto the umbrella pole of a parasol or similar cylindrical objects, so that when using a parasol in summer, there is no need to hold a fan, improving the convenience of use. The silicone pad 12 can provide protection for the clamped object and increase friction to improve the clamping stability.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
