[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] refer to Figure 1 This utility model discloses a clip-on fan 10, which is a small, portable cooling fan. When in use, the clip-on fan 10 can be hung on the user's collar, backpack shoulder strap, or chest pocket to provide cooling. In some embodiments, the clip-on fan 10 can also be clipped to a cuff, belt, or other location to provide cooling, thus expanding its application scenarios.

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The mounting fan 10 may include a fan assembly 11 and a mounting bracket 12. The fan assembly 11 includes a first mounting base 111, a second mounting base 112, a fan assembly 113, and a power module 114. The first mounting base 111 is connected to the second mounting base 112 and has a first air inlet 111a and an air outlet 111b. The air outlet 111b is located on the side of the first mounting base 111. The fan assembly 113 is disposed within the first mounting base 111, and the power module 114 is disposed within the second mounting base 112 and is used to supply power to the fan assembly 113. The mounting bracket 12 is rotatably connected to at least one of the first mounting base 111 and the second mounting base 112, so that the first mounting base 111 can rotate relative to the mounting bracket 12 to adjust the orientation of the air outlet 111b. The mounting bracket 12 is used to hang the mounting fan 10 on an external support. When in use, the user can hang the clip fan 10 on an external support such as a collar or a shoulder bag by using the hanging part 12 of the clip fan 10, and adjust the orientation of the air outlet 111b by rotating the first mounting base 111 relative to the hanging part 12, for example, so that the air outlet 111b faces the neck or face, thus eliminating the need to hold it with your hand continuously as with a handheld fan, improving the convenience of use.

[0028] refer to Figure 4 In some embodiments, the power module 114 may include a battery 1141 and a circuit board 1142. The circuit board 1142 is electrically connected to the battery 1141, and the fan assembly 113 is electrically connected to the circuit board 1142. The battery 1141 may be a lithium battery, capable of providing power to the fan assembly 113. The control circuit of the fan assembly 113 may be integrated on the circuit board 1142 to realize functions such as turning on and off the hanging fan 10.

[0029] refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the first mounting base 111 and the second mounting base 112 are fixedly connected, and an air intake channel 115 extending circumferentially along the fan assembly 11 is formed between the first mounting base 111 and the second mounting base 112, the air intake channel 115 communicating with the first air inlet 111a. In some embodiments, the first end 121 of the holder 12 extends into the air intake channel 115, and the air intake channel 115 surrounds the fan assembly 11 completely. Alternatively, the first end 121 of the holder 12 extends between the first mounting base 111 and the second mounting base 112. In other embodiments, the air intake channel 115 does not necessarily surround the fan assembly 11 completely; for example, the central angle of the air intake channel is 270 degrees to 300 degrees. Figure 2As shown, the first mounting base 111 and the second mounting base 112 can be cylindrical and have approximately the same diameter, so that the fan assembly 11 is cylindrical in shape. The first mounting base 111 and the second mounting base 112 are fixedly connected and have an axial gap between them to form an air intake channel 115. The width of the air intake channel 115 in the axial direction of the fan assembly 11 is not less than the thickness of the hanging member 12, so that the first end 121 of the hanging member 12 can rotate relative to the first mounting base 111 in the air intake channel 115.

[0030] refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the first mounting base 111 forms a protruding mounting portion 111c on the side facing the second mounting base 112, such as... Figure 6 As shown, the mounting portion 111c can be annular in shape. Multiple first air inlets 111a can be provided and extend circumferentially around the mounting portion 111c, spaced apart from it. The mounting portion 111c is detachably connected to the second mounting base 112, for example, by screws. The first end 121 of the hanging member 12 extends into the air intake channel 115 and is rotatably connected to the mounting portion 111c. In other embodiments, the mounting portion 111c can be formed on the side of the second mounting base 112 facing the first mounting base 111. In other words, one of the first mounting base 111 and the second mounting base 112 forms a protruding mounting portion 111c on the side facing the other, to cooperate with the hanging member 12, allowing the hanging member 12 to rotate relative to the first mounting base 111.

[0031] Furthermore, the fan assembly 11 includes a resilient clip 116 disposed in the mounting portion 111c, and the first end 121 of the hanging member 12 has a first through hole 121a, the first through hole 121a being fitted onto the mounting portion 111c, and the inner wall of the first through hole 121a having a plurality of slots 121b. Specifically, as shown... Figure 6 As shown, the mounting portion 111c may have a locking groove 111c1 for accommodating the elastic locking member 116, and a locking opening 111c2 disposed on one side wall of the locking groove 111c1. The elastic locking member 116 may include an elastic member 1161, an abutting portion 1162 abutting against the elastic member 1161, and a first locking tooth 1163 disposed on the abutting portion 1162 on the side opposite to the elastic member 1161. In some embodiments, the elastic member 1161 may be a spring, the elastic locking member 116 is disposed in the locking groove 111c1, one end of the elastic member 1161 abuts against the groove wall of the locking groove 111c1, and the other end abuts against the abutting portion 1162, and the first locking tooth 1163 of the elastic locking member 116 protrudes from the mounting portion 111c through the locking opening 111c2 of the mounting portion 111c.

[0032] In some embodiments, the hanging member 12 includes a hanging member 122 and a retaining ring 123 fixedly connected to the hanging member 122. The portion of the hanging member 122 used to connect to the retaining ring 123, together with the retaining ring 123, forms the first end 121 of the hanging member 12. The hanging member 122 has a mounting hole 1221, and the retaining ring 123 is disposed within the mounting hole 1221 and fixedly connected to the hanging member 122. The retaining ring 123 has a first through hole 121a and a groove 121b. The inner wall of the retaining ring 123 may have multiple second retaining teeth 1231, and a groove 121b is formed between adjacent second retaining teeth 1231. During the rotation of the hanging member 12 relative to the first mounting base 111, the retaining ring 123 rotates relative to the mounting part 11c. The first retaining tooth 1163 is pressed by the retaining ring 123 and extends and retracts relative to the mounting part 11c to slide from one groove 121b into another adjacent groove 121b, thereby locking the retaining ring 123 with the mounting part 11c and preventing the fan assembly 11 from easily rotating relative to the hanging member 12 to maintain the relative position of the air outlet 111b. When the user needs to drive the hanging member 12 to rotate relative to the fan assembly 11 again, he only needs to overcome the resistance of the second retaining teeth 1231 to the elastic retaining member 116. During this process, the first locking tooth 1163 and the second locking tooth 1231 continuously engage alternately, providing a tactile feedback to the user and ensuring reliable positioning of the fan assembly 11 on the mounting bracket 12 to maintain the orientation of the air outlet 111b.

[0033] Of course, in other embodiments, the hanger 122 and the retaining ring 123 can be integrally formed to simplify the structure of the hanger 12.

[0034] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the hanging member 12 may include a second end 124, which spans across the second mounting base 112 and extends to the side of the second mounting base 112 opposite to the first mounting base 111. During use, the user can squeeze a collar or backpack strap between the second end 124 of the hanging member 12 and the second mounting base 112, thereby increasing the gap between the second end 124 of the hanging member 12 and the second mounting base 112. This achieves the opening of the hanging member 12 relative to the second mounting base 112, and the deformation of the bent portion of the hanging member 12 can accumulate elastic potential energy. In other words, when the support with thickness enters the space between the hanger 12 and the second mounting base 112, it can cause the bent part of the hanger 12 to undergo elastic deformation. The restoring force of the elastic deformation causes the second end 124 of the hanger 12 to tend to retract towards the second mounting base 112, thereby reliably clamping the support such as the collar or backpack strap between the hanger 12 and the second mounting base 112, preventing the hanging fan 10 from easily falling off the external support.

[0035] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the first mounting base 111 may include a mounting plate 1111, a cover 1112 connected to the mounting plate 1111, and a decorative cover 1113 connected to the cover 1112. A fan assembly 113 is connected to the mounting plate 1111. The cover 1112 covers the fan assembly 113 and has an air outlet 111b. The mounting plate 1111 is connected to the second mounting base 112 and has a first air inlet 111a. Specifically, as... Figure 4 As shown, the cover 1112 has a receiving cavity 11121, a second engaging protrusion 11122, and a positioning groove 11123. The second engaging protrusion 11122 and the positioning groove 11123 are disposed on the inner wall edge of the receiving cavity 11121. The mounting plate 1111 has a second engaging groove 11111 that mates with the second engaging protrusion 11122, and a positioning protrusion 11112 that protrudes from the second engaging groove 11111. The cover 1112 uses the second engaging protrusion 11122 to match the second engaging groove 11111 of the mounting plate 1111 to limit the mounting plate 1111 within the cover 1112, preventing the mounting plate 1111 from easily detaching from the cover 1112. The positioning groove 11123 of the mounting plate 1111 matches the positioning protrusion 11112 of the cover 1112 to prevent the cover 1112 from rotating relative to the mounting plate 1111.

[0036] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the first mounting base 111 has a second air inlet 1114 on the side opposite to the second mounting base 112. In the axial direction of the fan assembly 113, the decorative cover 1113 is located on the side of the cover body 1112 away from the second mounting base 112. The decorative cover 1113 and the cover body 1112 form the second air inlet 1114. The first air inlet 111a and the second air inlet 1114 are distributed on opposite sides of the fan assembly 113 in the axial direction. Because the first air inlet 111a and the second air inlet 1114 are correspondingly provided on opposite sides of the fan assembly 113 in the axial direction, the clip-on fan 10 can have a larger air intake volume during operation compared to a single air inlet, thereby creating a better positive pressure effect within the receiving cavity 11121, increasing the airflow velocity at the air outlet 111b, and enhancing the heat dissipation effect.

[0037] Continue to refer to Figure 3 , Figure 4 and Figure 5In some embodiments, the fan assembly 11 further includes a circuit board 11a, a light-emitting module 11b, a display module 11c, a light-transmitting element 11d, and a fixing element 11e. The circuit board 11a is connected to the cover 1112. The light-emitting module 11b and the display module 11c are electrically connected to the circuit board 11a and disposed on the side of the circuit board 11a opposite to the second mounting base 112. The circuit board 11a can be electrically connected to the power supply assembly 114, which supplies power to the light-emitting module 11b and the display module 11c. The light-transmitting element 11d may have a frosted surface and cover the light-emitting module 11b, and has a certain degree of light transmittance, for example, a transmittance of 50%-60%. The light-emitting module can be an LED light, thereby providing supplementary lighting for the user when powered on. The decorative cover 1113 covers the display module 11c and has a certain degree of light transmittance, for example, a transmittance of 50%-60%. The display module 11c can be a digital tube for displaying battery power information. The structure in which the positioning groove 11123 of the mounting plate 1111 matches the positioning protrusion 11112 of the cover 1112 can prevent the cover 1112 from rotating relative to the mounting plate 1111, which would cause the connecting cables of the light-emitting module 11b and the display module 11c to be twisted.

[0038] The second air inlet 1114 extends from the side of the light-transmitting element 11d away from the second mounting base 112, through the circuit board 11a and the cover 1112, into the cover 1112. For example... Figure 3 As shown, the cover 1112 has a first mounting groove 11124, a second mounting groove 11125, and a second connecting part 11126 disposed at the bottom of the first mounting groove 11124 on the side opposite to the fan assembly 113. The circuit board 11a is accommodated and confined within the first mounting groove 11124, and the light-transmitting element 11d covers the circuit board 11a and is disposed within the second mounting groove 11125. The fastener 11e may have a third mounting groove 11e1, a protrusion 11e2, and a second connecting hole 11e3 disposed around the third mounting groove 11e1. The display module 11c is accommodated and confined within the third mounting groove 11e1. The second connecting part 11126 abuts against the protrusion 11e2 and matches the second connecting hole 11e3 of the fastener 11e, facilitating the installation of fasteners such as screws through the second connecting part 11126 and the second connecting hole 11e3, reliably confining the circuit board 11a, the light-emitting module 11b, the display module 11c, and the light-transmitting element 11d on the cover 1112. Both the circuit board 11a and the light-transmitting element 11d have through holes 11f, which are constructed as part or all of the second air inlet 1114.

[0039] refer to Figure 2 , Figure 4 and Figure 5In some embodiments, the clip-on fan 10 includes a bracket 13 rotatably connected to the holder 12. The bracket 13 can switch between an open state and a retracted state. In the retracted state, the bracket 13 is attached to the side of the holder 12 opposite to the second mounting base 112. In the open state, the bracket 13 and the holder 12 can form an angle on the side opposite to the second mounting base 112, for example, the angle can be 90 degrees or greater. This allows the user to tilt the clip-on fan 10 onto a flat surface, such as a table, for cooling, or to position the side of the first mounting base 111 containing the light-emitting module 11b towards the user, facilitating supplemental lighting through the light-emitting module 11b. For example, in a dimly lit environment, when a user uses a mobile phone, the fan assembly 11 is tilted and supported on a table by the bracket 13 and the holder 12. The light-emitting module 11b provides supplemental lighting for the user, serving as a background light for the phone to improve eye comfort, while the fan assembly 11 dissipates heat from the back of the phone or the user. Of course, in some implementations, the light-emitting module 11 and the fan assembly 113 are controlled independently. For example, the light-emitting module 11 and the fan assembly 113 can be controlled one-to-one by two physical buttons. When supplementary lighting is not needed, only the fan assembly 113 can be turned on, and when heat dissipation is not needed, only the light-emitting module 11 can be turned on, thereby reducing the energy consumption of the clip fan 10.

[0040] refer to Figure 3 , Figure 4 and Figure 6 In some embodiments, the second mounting base 112 has a wiring hole 112a and a protruding limiting block 112b on the side facing the first mounting base 111. The mounting part 111c has a limiting hole 111c3 that mates with the limiting block 112b, and the limiting hole 111c3 communicates with the wiring hole 112a. Specifically, the second mounting base 112 may include a protective shell 1121 and a shell cover 1122. The wiring hole 112a and the limiting block 112b are disposed on the shell cover 1122, and the shell cover 1122 has a first connecting hole 11221. The mounting part 111c has a first connecting part 111c4 that matches the first connecting hole 11221 of the shell cover 1122. When the cover 1122 is assembled with the first mounting base 111, the first wiring hole 112a and the limiting block 112b of the cover 1122 match the second wiring hole 112a of the first mounting base 111, so that the cover 1122 and the first mounting base 111 can be installed and positioned. The first connecting hole 11221 of the cover 1122 matches the first connecting part 111c4 of the first mounting base 111, and the cover 1122 and the first mounting base 111 can be assembled and fixed by using threaded fasteners such as screws.

[0041] refer to Figure 3 , Figure 4In some embodiments, the edge of the cover 1122 may have multiple spaced-apart first engaging grooves 11222, and the protective shell 1121 has a mounting cavity 11211 with multiple first engaging protrusions 11212 disposed on the inner wall of the mounting cavity 11211 and corresponding one-to-one with the multiple first engaging grooves 11222. When the second mounting base 112 is assembled, the power module 114 can be disposed in the mounting cavity 11211 of the protective shell 1121, and the cover 1122 is engaged with and covers the mounting cavity 11211 by the first engaging grooves 11222 and the first engaging protrusions 11212 of the protective shell 1121, thereby protecting the power module 114.

[0042] refer to Figure 5 In some embodiments, the side of the cover 1112 is provided with a plurality of decorative protrusions 11127 arranged circumferentially along the side of the cover 1112 to enhance the aesthetics of the clamping fan 10. The decorative protrusions 11127 may be in the shape of a square pyramid or other shapes such as a square pyramid or rectangle, as long as they can form an attractive pattern on the surface of the clamping fan 10.

[0043] refer to Figure 3 , Figure 4 , Figure 5 and Figure 8 In some embodiments, the fan assembly 113 includes a drive member 1131 and a fan blade 1132 linked to the drive member 1131. The drive member 1131 is connected to the first mounting base 111. The fan blade 1132 includes an integrally formed blade 11321, a support 11322, and a fixing ring 11323. The support 11322 has a groove 1132a for accommodating the drive member 1131. One end of the blade 11321 is connected to the support 11322, and the other end is connected to the fixing ring 11323, so as to fix both ends of the blade 11321, avoid the blade 11321 from shaking when rotating at high speed, and thus enhance the rotational stability of the fan blade 1132. In the axial direction of the fan blade 1132, a retaining ring 11323 is located at the end of the blade 11321 opposite to the second mounting base 112 and surrounds the support 11322. The retaining ring 11323 is also spaced apart from the support 11322 in the radial direction of the fan blade 1132. The area between the retaining ring 11323 and the support 11322 corresponds to the second air inlet 1114 to ensure smooth airflow into the second air inlet 1114 and reduce airflow resistance. In the radial direction of the fan blade 1132, one side of the blade 11321 is concave, and the opposite side is convex. For example, in... Figure 8In the illustrated embodiment, each blade 11321 extends obliquely in a counterclockwise direction, and each blade 11321 protrudes outward in a counterclockwise direction at one end near the fixing ring 11323, while the opposite side is concave to form an arc-shaped surface. This structure can more effectively guide airflow to the air outlet 111b on the side of the first mounting base 111, obtaining greater airflow under the same rotational speed and improving heat dissipation efficiency. In some embodiments, the drive element 1132 can be a combination of a rotor and a stator to reduce the size of the clamp fan 10.
