Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a desktop fan. Background Technology

[0002] Desktop fans are generally small in size and are designed to be placed on a desktop or other support to cool the user. However, when using a desktop fan, if a user needs to charge their mobile phone or other electronic devices, they usually need to use a power adapter or power bank with a charging cable, which is inconvenient. Utility Model Content

[0003] This utility model provides a desktop fan that improves user convenience.

[0004] A desktop fan, comprising:

[0005] The housing assembly has a cable outlet;

[0006] A fan is disposed on the housing assembly; and

[0007] A telescopic cable module is disposed on the housing assembly and includes a cable that can extend and retract relative to the housing assembly, and a connector connected to one end of the cable. The cable outlet is used for the connector to pass through the housing assembly to the outside of the housing assembly. The cable can be housed in the housing assembly and can be pulled out from the cable outlet to connect to an external electronic device via the connector.

[0008] The above-mentioned desktop fan allows users to extend the retractable cable module from the fan's housing when an external device has a rechargeable battery and requires charging. The connector can then be plugged into a mobile phone or other external electronic device, allowing the fan to power and charge it without the need for an additional charger or power bank, thus improving convenience. Even when the external device doesn't have a rechargeable battery, the retractable cable module can still power it. When powering the device is no longer needed, the cable can be retracted into the housing, maintaining the fan's clean and simple appearance. The cable outlet allows the connector to pass through the housing, ensuring smooth assembly of the retractable cable module and housing.

[0009] A desktop fan, comprising:

[0010] A housing assembly includes a first housing and a second housing connected to the first housing, wherein the first housing and the second housing together form a cable outlet.

[0011] A fan is disposed on the housing assembly; and

[0012] A telescopic cable module is disposed in the housing assembly and includes a cable that can extend and retract relative to the housing assembly, and a connector connected to one end of the cable, the width of the connector being greater than the width of the outlet; the cable can be housed within the housing assembly and can be pulled out from the outlet to connect to an external electronic device via the connector.

[0013] The above-mentioned desktop fan allows users to extend the retractable cable module from the fan's housing when an external device has a rechargeable battery and requires charging. The connector can then be plugged into a mobile phone or other external electronic device, allowing the fan to power and charge it without the need for an additional charger or power bank, thus improving convenience. Even when the external device doesn't have a rechargeable battery, the retractable cable module can still power it. When powering the device is no longer needed, the cable can be retracted into the housing, maintaining the fan's clean appearance. Since the connector is wider than the cable outlet, the first and second housings together form the outlet. During assembly, the cable can be threaded through this outlet between the first and second housings before securing them together, ensuring a smooth assembly. Attached Figure Description

[0035] First Embodiment

[0036] refer to Figure 1 , Figure 2 and Figure 3 The first embodiment of this application discloses a desktop fan 100, which includes a housing assembly 110, a fan 120, and a telescopic cable module 130. The housing assembly 110 is used to support the desktop fan 100 on an external support such as a desktop, and the housing assembly 110 has a cable outlet 110a. The fan 120 is disposed in the housing assembly 110. The fan 120 can be an axial fan. The telescopic cable module 130 is disposed in the housing assembly 110 and includes a cable 131 that can extend and retract relative to the housing assembly 110, and a connector 133 connected to one end of the cable 131. The cable 131 can be housed inside the housing assembly 110 and can be pulled out from the cable outlet 110a to connect to an external electronic device through the connector 133 to supply power to the external electronic device.

[0037] In some embodiments, the desktop fan 100 may further include a power module 140 disposed within the housing assembly 110, the power module 140 being used to power the fan 120. The power module 140 generally includes a rechargeable battery, such as a lithium battery, and with the advancement of battery technology, battery capacity has been continuously increasing, thus steadily improving the battery life of the desktop fan 100.

[0038] The cable 131 can be coiled and stored inside the housing assembly 110 to achieve a concealed effect, keeping the desktop fan 100 in a relatively simple appearance and preventing the cable 131 from causing inconvenience to the user during daily use, such as preventing it from getting tangled with other items during transportation or when not in use. When the user needs to power external electronic devices such as mobile phones, the cable 131 of the retractable cable module 130 can be pulled out from the housing assembly 110 and connected to the external electronic device via the connector 133. The power module 140 of the desktop fan 100 then powers these external electronic devices, such as charging mobile phones, tablets, or game controllers, improving ease of use. When the external electronic device does not have a rechargeable battery, the user can also use the retractable cable module 130 of the desktop fan 100 to power it. When the user no longer needs to power external electronic devices through the desktop fan 100, the cable 131 of the retractable cable module 130 can be stored inside the housing assembly 110, and the desktop fan 100 can still maintain a relatively simple appearance.

[0039] Of course, in some embodiments, the retractable cord module 130 can also connect to other types of external electronic devices via the connector 133 to power the fan 120. For example, it can connect to external electronic devices such as power banks, emergency power supplies, power adapters, or indoor sockets with integrated discharge ports to power the fan 120, improving ease of use. In embodiments where the desktop fan 100 includes a power module 140, the retractable cord module 130 can also connect to external electronic devices such as power banks, emergency power supplies, power adapters, or indoor sockets with integrated discharge ports via the connector 133 to charge the power module 140, thus achieving reverse charging and indirectly or directly powering the fan 120. The power supply circuit of the fan 120 or the reverse charging circuit of the power module 140 are relatively mature existing technologies and will not be described in detail here.

[0040] In some embodiments, the retractable cable module 130 may have a digital display unit located at the connector 133. This display unit may include a display panel, such as an LCD panel or an OLED panel, to display information such as current and voltage during the operation of the cable 131, improving ease of use. The connector 133 is not limited to a Type-C interface, or a Micro-USB interface, or a Lightning interface, or a magnetic charging interface, etc., and will not be described further here.

[0041] Of course, in other embodiments, the power module 140 can be omitted. In an embodiment where the power module 140 is omitted, when the user needs to use the desktop fan 100, they can plug it into an indoor power outlet or connect it to another type of external power source, such as a power bank, using an external power source to power the fan 120. In this embodiment using an external power source, the desktop fan 100 can still be configured to connect to an external electronic device via the connector 133 of the retractable cable module 130 after connecting to an external power source, and power the external electronic device through the retractable cable module 130, thus avoiding the need to use an additional power adapter or power bank with a charging cable to power the external electronic device. This application uses a desktop fan 100 including the power module 140 as an example for explanation. In the embodiment where the power module 140 is omitted, the external power source can be easily converted into voltage and current to power the external electronic device through a transformer circuit and its associated control circuit. These are relatively mature technical solutions, and this application will not elaborate on them further.

[0042] Also refer to Figure 4 and Figure 5 The housing assembly 110 may include a head housing 111 and a bottom housing 113, and a connecting rod 115 connecting the head housing 111 and the bottom housing 113, with the opposite ends of the connecting rod 115 rotatably connected to the head housing 111 and the bottom housing 113 respectively. A fan 120 is disposed on the head housing 111, which has an air outlet 111a and an air inlet 111b. A telescopic cord module 130 is disposed on the bottom housing 113, which has a cord outlet 110a. In embodiments where the desktop fan 100 includes a power module 140, the power module 140 may also be disposed on the bottom housing 113. A first circuit board 150 may also be disposed inside the bottom housing 113, integrating the control circuit and power management unit of the desktop fan 100, with the fan 120, cord 131, and power module 140 electrically connected to the first circuit board 150. The bottom shell 113 or the head shell 111 may also be equipped with buttons for controlling the start and stop of the desktop fan 100. These buttons are not limited to physical buttons; they can also be virtual buttons, such as those implemented using a touchscreen. The bottom shell 113 may also be equipped with a dial or other structure for adjusting the speed of the fan 120. These structures can be configured to correspond to the trigger structures on the circuit board. The first circuit board 150 inside the bottom shell 113 can be electrically connected to the fan 120 inside the head shell 111 via circuit wiring. For example, the connecting rod 115 may be hollow internally, with the circuit wiring passing through the bottom shell 113, through the hollow connecting rod 115, and connecting to the fan 120 inside the head shell 111. This provides better protection for the circuit wiring and reduces the probability of damage caused by accidental pulling.

[0043] In other embodiments, the power module 140 may be disposed on the head housing 111, and the telescopic cable module 130 may also be disposed on the head housing 111. The dial may also be disposed on the head housing 111.

[0044] The head shell 111 has a retracted state and an open state relative to the bottom shell 113, as shown in the reference. Figure 1 In the retracted state, connecting rod 115 is stacked on bottom shell 113, and head shell 111 is stacked on connecting rod 115, with the axis of head shell 111 and the axis of bottom shell 113 basically coinciding; Reference Figure 4 and Figure 5 In the open state, the connecting rod 115 is set at an angle relative to the bottom shell 113, for example, forming an acute angle, and the head shell 111 is also set at an angle relative to the connecting rod 115, for example, forming an acute angle. In some embodiments, the head shell 111 and the bottom shell 113 are approximately cylindrical, with the air inlet 111b and the air outlet 111a correspondingly located at opposite ends of the head shell 111. The axis of the fan 120 can be substantially coincident with the axis of the head shell 111 to obtain a relatively better visual effect. A groove 111c matching the connecting rod 115 can also be provided at the end of the head shell 111 where the air inlet 111b is located, so that the connecting rod 115 can be fitted into the groove 111c in the retracted state, reducing the axial height of the entire desktop fan 100 in the retracted state and obtaining a more compact structure.

[0045] In the open state, the head shell 111 is supported by the connecting rod 115 and is spaced apart from or overlapped with the bottom shell 113. The axis of the head shell 111 can form an angle with the axis of the bottom shell 113 so that the air outlet 111a can face the user. Exemplarily, in some embodiments, when the bottom shell 113 is laid flat on a horizontal surface, the axis of the bottom shell 113 extends in the vertical direction, and the axis of the head shell 111 in the open state can extend in the horizontal direction. In other embodiments, the axis of the head shell 111 in the open state can have other angles relative to the axis of the bottom shell 113. The user only needs to adjust the angle of the connecting rod 115 relative to the bottom shell 113 and the angle of the head shell 111 relative to the connecting rod 115 according to the usage requirements to obtain a suitable air outlet angle. For example, the tilt angle of the head shell 111 relative to the table can be adjusted appropriately according to the user's sitting height, thereby improving the convenience and comfort of use.

[0046] To achieve instant positioning of the connecting rod 115 relative to the bottom shell 113 and the head shell 111 relative to the connecting rod 115 when in the open state, the rotational structures of the connecting rod 115 and the bottom shell 113, and the rotational structures of the head shell 111 and the connecting rod 115, can each have appropriate damping. For example, instant positioning can be achieved through a damping shaft, or by applying a compressive force to the two relatively rotating parts through a torsion spring, so that the two relatively rotating parts have appropriate frictional torque, thereby achieving the effect of instant positioning.

[0047] Furthermore, the bottom shell 113 has a storage groove 113a, which can be approximately spherical. Combined with... Figure 6 When the head shell 111 is in the retracted state, the end containing the air inlet 111b is housed in the storage slot 113a, and the circumferential surface of the head shell 111 is aligned and flush with the circumferential surface of the bottom shell 113. Figure 1 As shown. In the embodiment where the head shell 111 and bottom shell 113 are approximately cylindrical, the outer contour of the end where the air inlet 111b of the head shell 111 is located can be close to a hollowed-out frustum shape. The storage groove 113a is adapted to the outer contour of the end where the air inlet 111b of the head shell 111 is located, so that when the desktop fan 100 is in the folded state, the end where the air inlet 111b of the head shell 111 is located can be embedded in the storage groove 113a, so that the circumferential surface of the head shell 111 and the circumferential surface of the bottom shell 113 are aligned and flush, forming a highly integrated appearance and reducing the overall size of the desktop fan 100, making it convenient for users to store and move. In other words, in this embodiment, the outer diameter of the head shell 111 and the outer diameter of the bottom shell 113 are basically equal, so that the circumferential cylindrical surfaces of the head shell 111 and the bottom shell 113 of the desktop fan 100 in the folded state can be joined and smoothly transitioned, achieving a high degree of overall appearance integrity.

[0048] Further, refer to Figure 2 , Figure 3 and combined Figures 4 to 6 The bottom shell 113 may include a support plate 1131 and a support shell 1133 disposed on the support plate 1131. The support plate 1131 and the support shell 1133 enclose a storage groove 113a and a cavity 113b spaced apart from the storage groove 113a. A telescopic cable module 130 and a power module 140 are disposed in the cavity 113b. A connecting rod 115 is rotatably connected to the support plate 1131. The support shell 1133 is used to be placed on a support surface such as a desktop, and the support shell 1133 has a cable outlet 110a. The desktop fan 100 may also include a driver 160 disposed on the support housing 1133. The driver 160 may be an electric motor. The immovable structure of the electric motor, such as an outer casing, may be fixedly connected to the support housing 1133. The output end of the electric motor is linked with the support plate 1131 so that, when in the open state, the support plate 1131 and the connecting rod 115 drive the head shell 111 and the fan 120 inside to rotate relative to the support housing 1133, thereby adjusting the orientation of the air outlet 111a. In other words, in this embodiment, the driver 160 can realize the rotation of the head shell 111 in space, that is, realize the oscillation effect of the head shell 111 to change the orientation of the air outlet 111a, thereby improving the convenience and comfort of use. Of course, the driver 160 is not necessary and can be omitted. In the embodiment where the driver 160 is omitted, the support plate 1131 and the support housing 1133 may be fixedly connected.

[0049] Continue to refer to Figure 1 and combined Figure 4In some embodiments, the connector 133 has a larger cross-sectional dimension than the cable body 131, forming a stepped structure at the connection point between the cable body 131 and the connector 133. The width of the connector 133 is not greater than the width of the outlet 110a. In other words, the cross-sectional area of ​​the connector 133 is not greater than the cross-sectional area of ​​the outlet 110a, so that during assembly, the connector 133 can pass through the outlet 110a from inside the housing assembly 110, that is, move from the inside of the housing assembly 110 to the outside of the housing assembly 110. This allows the connector 133 to extend outside the housing assembly 110 after the telescopic cable module 130 is assembled into the housing assembly 110, ensuring smooth assembly of the telescopic cable module 130 and the housing assembly 110. It is understandable that the width of the outlet 110a is equal to or slightly larger than the width of the connector 133, or the cross-sectional area of ​​the outlet 110a is equal to or slightly larger than the cross-sectional area of ​​the connector 133, so as to prevent the outlet 110a from being too large and causing great damage to the overall appearance of the housing assembly 110.

[0050] refer to Figure 7 and Figure 8 The telescopic cable module 130 may include a housing 134 disposed within the base shell 113. The housing 134 is fixed in position relative to the power module 140, and the cable 131 is telescopically disposed within the housing 134. The housing 134 may be fixedly connected to the first circuit board 150 or to the base shell 113, thereby achieving relative fixation between the housing 134 and the first circuit board 150. The telescopic cable module 130, including the housing 134, can be manufactured as an independent module and assembled into the base shell 113, thereby improving assembly efficiency and ensuring the reliability of the telescopic cable module 130.

[0051] The telescopic cable module 130 may include a second circuit board 135, a torsion spring 136, and a turntable 137 disposed within a housing 134. The second circuit board 135 is fixedly positioned relative to the housing 134, for example, it is fixedly connected to the housing 134 or the bottom shell 113. The second circuit board 135 is electrically connected to the first circuit board 150, for example, through wire bonding. In other words, in this embodiment, the fan 120 and the power module 140 are electrically connected to the first circuit board 150, the cable 131 is electrically connected to the second circuit board 135, and the second circuit board 135 is electrically connected to the first circuit board 150, thereby achieving the electrical connection between the cable 131 and the first circuit board 150.

[0052] The torsion spring 136 can be helical, with one end fixed relative to the position of the housing 134 and the other end fixed relative to the position of the turntable 137. The turntable 137 and the housing 134 are rotatably connected; for example, one of the turntable 137 and the housing 134 has a rotating shaft, and the other has a shaft hole that mates with the rotating shaft. The wire 131 is wound around the outer periphery of the torsion spring 136. One of the second circuit board 135 and the turntable 137 has a contact pin (not shown), and the other has a ring conductor (not shown). The contact pin contacts the ring conductor and conducts electricity. The wire 131 is electrically connected to the contact pin or the ring conductor on the turntable 137, thereby realizing the electrical connection between the wire 131 and the second circuit board 135. For example, the second circuit board 135 is provided with a contact pin, the turntable 137 is provided with a ring conductor, and the wire 131 is electrically connected to the ring conductor; or the second circuit board 135 is provided with a ring conductor, the turntable 137 is provided with a contact pin, and the wire 131 is electrically connected to the contact pin, thereby achieving an electrical connection between the wire 131 and the second circuit board 135. Of course, the wire 131 can also be directly electrically connected to the second circuit board 135 through methods such as wire bonding.

[0053] The cable 131 can be held in place by the turntable 137. When the user pulls the cable 131, the turntable 137 rotates relative to the housing 134 in one direction, such as clockwise, gradually extending beyond the housing 134. During this process, the contact pin remains in contact with the annular conductor, ensuring the electrical connection between the cable 131 and the second circuit board 135. During this process, the torsion spring 136 accumulates elastic potential energy, causing the turntable 137 to tend to rotate counterclockwise. When the user no longer needs to power external electronic devices via the desktop fan 100, the torsion spring 136 releases its elastic potential energy, causing the cable 131 extending beyond the housing 134 to gradually retract into the housing 134.

[0054] refer to Figure 8 In some embodiments, the telescopic cable module 130 includes a limiting member 138 rotatably connected to the housing 134. The turntable 137 has a stop position 1371 and an unlock position 1373. During the process of the cable 131 being pulled out of the housing 134, when the cable 131 drives the turntable 137 to rotate to the stop position 1371 corresponding to the limiting member 138, the limiting member 138 restricts the rotation of the turntable 137. When the cable 131 continues to be pulled out of the housing 134 and drives the turntable 137 to rotate, the limiting member 138 rotates relative to the housing 134 and moves to the unlock position 1373, so that the cable 131 can be gradually wound into the housing 134. Figure 8 The turntable 137 is shown to have corresponding limiting grooves 137a and guide grooves 137b. The groove wall of the limiting groove 137a can be used as the stop position 1371, and the connection between the groove wall of the guide groove 137b and the groove wall of the limiting groove 137a is the unlock position 1373.

[0055] The sidewall of the guide groove 137b can guide and limit the movement of the end of the limiting member 138, so that during the pulling process of the cable 131, the end of the limiting member 138 continues to move along the guide groove 137b. When the user stops pulling the cable 131 out, the torsion spring 136 drives the turntable 137 to rotate in the opposite direction (e.g., clockwise), and the end of the limiting member 138 is guided by the sidewall of the guide groove 137b into the limiting groove 137a, thereby stopping the cable 131. When the user continues to pull the cable 131 out, the turntable 137 continues to rotate in the original direction (e.g., counterclockwise), and the end of the limiting member 138 exits the limiting groove 137a and enters the guide groove 137b, allowing the cable 131 to continue to be pulled out. It is understood that the above functions can be achieved by designing the depth and width of the guide groove 137b and the limiting groove 137a, which will not be elaborated further in this application.

[0056] When the user pulls the cable 131 out of the cover 134 and drives the turntable 137 to rotate, the end of the limiting member 138 moves along the guide groove 137b to the stop position 1371. At this time, if the user stops pulling the cable 131, under the action of the torsion spring 136, the end of the limiting member 138 abuts against the groove wall of the limiting groove 137a, and the turntable 137 stops rotating, thus achieving the stopping effect of the cable 131. When the user continues to pull the cable 131 out of the cover 134 and drives the turntable 137 to rotate, the limiting member 138 rotates relative to the cover 134 and retracts to the guide groove 137b. It can switch to the guide groove 137b and continue to move along the guide groove 137b, that is, reach the unlock position 1373. The turntable 137 can continue to rotate and make the cable 131 continuously extend out of the cover 134, or the cable 131 can gradually be wound back into the cover 134. The combination of the limit switch 138 and the turntable 137 enables the cable 131 to stop and automatically rewind, improving ease of use. Furthermore, the turntable 137 can be configured with two or more stopping positions 1371 and unlocking positions 1373, with each stopping position 1371 corresponding to one of the unlocking positions 1373, facilitating stopping when the cable 131 extends to different lengths.

[0057] Of course, in other embodiments, the limiting member 138 may have other structural forms. For example, the limiting member 138 is movably fitted to the bottom shell 113 and has a first state and a second state. In the first state, the wire 131 can be pulled out or retracted into the bottom shell 113; in the second state, the limiting member 138 abuts against the wire 131 and restricts the movement of the wire 131 relative to the bottom shell 113.

[0058] For example, the limiting member 138 slides with the bottom shell 113, and the sliding of the limiting member 138 with the bottom shell 113 has appropriate damping to prevent the limiting member 138 from easily retracting. When the user needs to stop the cable 131 while pulling it out, the limiting member 138 is pushed relative to the bottom shell 113 to the position that abuts against the cable 131, i.e., the second state, which can stop the cable 131 in the bottom shell 113; when the user needs to retract the cable 131 into the bottom shell 113, the limiting member 138 is pushed in the opposite direction to the first state. After the limiting member 138 no longer abuts against the cable 131, the cable 131 can be rolled back into the cover 134 under the action of the torsion spring 136 and the turntable 137.

[0059] For example, the limiting member 138 is rotatably engaged with the bottom shell 113. The limiting member 138 may have an eccentric wheel structure and appropriate rotational damping to prevent the limiting member 138 from easily retracting. When the user needs to stop the cable 131 while pulling it out, the limiting member 138 is rotated so that the eccentric wheel of the limiting member 138 presses against the cable 131, thus reaching the second state and stopping the cable 131 in the bottom shell 113. When the user needs to retract the cable 131 into the bottom shell 113, the limiting member 138 is rotated in the opposite direction to the first state. After the eccentric wheel of the limiting member 138 no longer presses against the cable 131, the cable 131 can be rewound into the cover 134 under the action of the torsion spring 136 and the turntable 137.

[0060] Both of the above-described limiting member 138 structures can stop the yarn 131, and combined with the torsion spring 136, they can achieve an automatic winding effect, improving ease of use. In other embodiments, the limiting member 138 can also adopt other structural forms to achieve the stopping effect on the yarn 131.

[0061] It is understandable that the housing 134 of the telescopic cable module 130 is not necessary and can be omitted to simplify the structure of the desktop fan 100 and improve its structural compactness. For example, the telescopic cable module 130 includes a torsion spring 136 and a turntable 137 rotatably connected to the bottom housing 113 or the first circuit board 150. One free end of the torsion spring 136 is connected to the turntable 137, and the other free end of the torsion spring 136 is fixed relative to the position of the first circuit board 150. The cable 131 is wound around the outer periphery of the torsion spring 136 and is directly electrically connected to the first circuit board 150, for example, by soldering or by combining lead wires, or the cable 131 is electrically connected to the first circuit board 150 through a contact pin and a ring conductor. The cable 131 can be held in place by the turntable 137. When the user pulls the cable 131, it causes the turntable 137 to rotate relative to the bottom shell 113 in one direction, such as clockwise, so that it gradually extends out of the bottom shell 113. During this process, the torsion spring 136 accumulates elastic potential energy, causing the turntable 137 to tend to rotate counterclockwise. When the user no longer needs to power external electronic devices through the desktop fan 100, the torsion spring 136 releases its elastic potential energy, causing the cable 131 extending out of the bottom shell 113 to gradually retract into the bottom shell 113.

[0062] In this embodiment, the desktop fan 100 may also include a limiting member 138 that is movably fitted to the bottom shell 113. The limiting member 138 has a first state and a second state. In the first state, the cable 131 can be pulled out or retracted into the bottom shell 113. In the second state, the limiting member 138 abuts against the cable 131 and restricts the movement of the cable 131 relative to the bottom shell 113. The principle and structure of the limiting member 138 in stopping the cable 131, as well as the principle and structure of unlocking the cable 131, can be referred to the foregoing content and will not be repeated here.

[0063] In some embodiments, the connector 133 has a first position and a second position relative to the bottom shell 113. In the first position, the cable 131 is housed within the bottom shell 113, and the connector 133 is at least partially housed within the outlet 110a. Figure 9 As shown. In the second position, the cable 131 and connector 133 extend out of the bottom housing 113 for docking with external electronic devices. In other words, in the first position, connector 133 can partially protrude beyond the outlet 110a to prevent it from extending too far out of the bottom housing 113 and causing inconvenience, while also allowing the user to easily pinch connector 133 with their fingers and pull connector 133 and cable 131 out of the bottom housing 113. Of course, in the first position, connector 133 can also be completely retracted into the outlet 110a.

[0064] Simultaneously combined Figure 10 and Figure 11In this embodiment, the desktop fan 100 may include a pop-out assembly 170 disposed on the bottom shell 113. The pop-out assembly 170 is triggered to pop the connector 133 in a first position out of the bottom shell 113 from the cable outlet 110a. Specifically, the pop-out assembly 170 may include an elastic element 171 disposed within the bottom shell 113 and a slider 172 connected to the elastic element 171. During the process of the connector 133 switching from a second position to a first position, the connector 133 drives the slider 172 to move within the bottom shell 113 and lock in the first position, while the elastic element 171 accumulates elastic potential energy, such as... Figure 11 As shown. Slider 172 is triggered to unlock from the bottom shell 113; elastic element 171 then drives slider 172 to eject the connector 133 from the bottom shell 113, as... Figure 10 As shown.

[0065] Specifically, in some embodiments, the pop-out assembly 170 includes a mounting base 173 connected to the base shell 113, and a pull rod 174 rotatably connected to the mounting base 173 at one end. A slider 172 is slidably engaged with the mounting base 173. One end of an elastic element 171 is connected to the mounting base 173, and the other end is connected to the slider 172. The other end of the pull rod 174 is slidably engaged with the slider 172. During the process of the connector 133 being pressed into the outlet 110a and moving to the first position, the connector 133 drives the slider 172 to move relative to the mounting base 173, so that the pull rod 174 engages with the slider 172 at the first position. When the pull rod 174 engages with the slider 172, the connector 133 is pushed inward along the outlet 110a, and the pull rod 174 can unlock from the slider 172. The elastic element 171 can then push the connector 133 out of the outlet 110a through the slider 172.

[0066] Specifically, the slider 172 may have a groove 175, which includes an entry groove 175a, an engagement groove 175b, and an exit groove 175c. The engagement groove 175b communicates with both the entry groove 175a and the exit groove 175c, and the exit groove 175c communicates with the entry groove 175a. The bottom wall of the entry groove 175a has multiple steps to increase the depth of the entry groove 175a from its entrance to the engagement groove 175b. The depth of the exit groove 175c is less than the depth of the engagement groove 175b, and the bottom wall of the exit groove 175c smoothly transitions to the bottom wall of the engagement groove 175b. The depth of the exit groove 175c is less than the depth of the entrance to the entry groove 175a, thereby preventing the free end of the pull rod 174 from being mistakenly pushed into the exit groove 175c at the entrance of the entry groove 175a. Pushing the connector 133 inward along the outlet 110a, the free end of the pull rod 174 slides into the inlet of the inlet groove 175a and slides along the extension direction of the inlet groove 175a to slide into the engagement groove 175b. The pull rod 174 engages with the slider 172 in the engagement groove 175b, so that the slider 172 is locked to the mounting base 173, and the connector 133 reaches the first position. When the pull rod 174 engages with the slider 172, pushing the connector 133 inward along the outlet 110a, the pull rod 174 slides into the exit groove 175c and slides along the extension direction of the exit groove 175c towards the inlet of the inlet groove 175a. The elastic element 171 pushes the connector 133 out of the outlet 110a through the slider 172.

[0067] In this pop-up component 170, during the process of the cable 131 being stored in the bottom shell 113, the user pushes the connector 133 into the cable outlet 110a. The stepped structure formed by the height difference between the connector 133 and the cable 131 can push the slider 172 to move, thereby causing the free end of the pull rod 174 to move in the slide groove 175 and engage with the engagement groove 175b. When the free end of the pull rod 174 is engaged with the engagement groove 175b, the connector 133 reaches the first position, and the slider 172 is locked inside the bottom shell 113. The user can easily put the desktop fan 100 into a bag or pocket, preventing the connector 133 from hanging directly outside the bottom shell 113 and adversely affecting the convenience of use. With this structural design, when the connector 133 is in the first position, the bottom shell 113 can also protect the connector 133, preventing it from being scratched or damaged due to accidental collisions.

[0068] When the user needs to use connector 133 to power an external electronic device, pushing connector 133 into the outlet 110a causes the step structure formed by the height difference between connector 133 and cable 131 to push slider 172 further into the bottom shell 113. This causes the free end of pull rod 174 to move in the slide groove 175, disengaging from engagement groove 175b and moving to exit groove 175c. Under the restoring force of elastic element 171, slider 172 is driven to reset, pushing connector 133 out of outlet 110a, thus enabling connector 133 to pop out of bottom shell 113. When slider 172 resets to its initial position, connector 133 can be considered to have moved to the second position. At this point, the user can easily pinch connector 133, pull cable 131 out of bottom shell 113, and connect connector 133 to external electronic device to power it.

[0069] refer to Figure 12 and Figure 13 In other embodiments, the slider 172 has an integrally formed body 1721 and a stop 1723. An elastic element 171 is connected to the body 1721. The ejection assembly 170 includes a mounting box 176 fixed relative to the bottom shell 113, and a latch 177 movably disposed in the mounting box 176. During the switching of the connector 133 from the second position to the first position, the connector 133 drives the slider 172 to move within the bottom shell 113 and causes the stop 1723 to pass over the latch 177. At the first position, the latch 177 locks with the stop 1723, thereby positioning the connector 133 in the first position. The latch 177 can be driven to open so that the stop 1723 can be disengaged from the latch 177 by the elastic element 171, and the slider 172 drives the connector 133 to eject from the bottom shell 113. The mounting box 176 may have a spring or other structure inside, or the pawl 177 may be used in conjunction with a torsion spring or other structure to give the pawl 177 a tendency to remain closed, so that the stop portion 1723 of the slider 172 is reliably held within the pawl 177 in the first position. By using an exposed button, pull cord, or other structure, the pawl 177 can be opened, and the elastic element 171 can push the slider 172 back to its original position, thereby using the slider 172 to push the connector 133 out of the bottom shell 113.

[0070] See again Figure 2 , Figure 3 and Figure 4In some embodiments, when the connector 133 is not used, it may be entirely located outside the base shell 113. The desktop fan 100 may include a decorative ring 180, which passes through the cable outlet 110a and is confined within the base shell 113. The decorative ring 180 has a through hole for the cable 131 to pass through, and the width of the through hole is smaller than the width of the connector 133. In other words, the cross-sectional area of ​​the through hole is smaller than the cross-sectional area of ​​the connector 133. The through hole allows the cable 131 to extend and retract freely, but restricts the connector 133 from being retracted into the base shell 113 and appropriately seals the cable outlet 110a to prevent dust or droplets from easily entering the excessively large cable outlet 110a, thereby achieving a certain degree of waterproof and dustproof effect and preventing the excessively large cable outlet 110a from damaging the overall appearance of the base shell 113, thus improving the overall appearance of the base shell 113.

[0071] In this embodiment, the decorative ring 180 can be an open ring. The material of the open ring decorative ring 180 is not limited to hardware (such as stainless steel), silicone or rubber, etc. It can be conveniently fitted around the outer periphery of the wire body 131. During the assembly of the telescopic wire module 130 and the bottom shell 113, the connector 133 passes through the wire outlet 110a from inside the bottom shell 113 to the outside of the bottom shell 113. The decorative ring 180 fitted on the wire body 131 can be moved to the position of the wire outlet 110a and riveted, glued or snapped to the bottom shell 113 at the wire outlet 110a, thereby ensuring the connection stability between the decorative ring 180 and the bottom shell 113. Of course, in other embodiments, the decorative ring 180 can be a circumferentially closed ring structure, and its material can be elastic silicone or rubber, etc. By stretching the decorative ring 180 to deform it, it can also be easily inserted into the connector 133 and fitted onto the wire body 131, thereby limiting the decorative ring 180 to the bottom shell 113 at the outlet 110a.

[0072] Furthermore, the bottom shell 113 may have a recess 110c communicating with the cable outlet 110a, the cable outlet 110a being located at the bottom of the recess 110c, and the cable 131 being bendable to confine the connector 133 within the recess 110c. For example, the desktop fan 100 may include a magnetic member 191, which is connected to the bottom shell 113 and positioned corresponding to the bottom of the recess 110c. The connector 133 has a mating member 193, which magnetically engages with the magnetic member 191 to attach the connector 133 to the bottom of the recess 110c. Furthermore, one surface of the connector 133 in the thickness direction may be fitted to the bottom of the recess 110c; this surface may have a relatively large area, and the depth of the recess 110c need not be too large, to avoid excessively affecting the overall appearance of the bottom shell 113.

[0073] One of the magnetic attractor 191 and the mating part 193 is a magnet, and the other is a magnet or a ferromagnetic metal such as iron, cobalt, nickel, or their alloys. The magnetic attraction between the magnetic attractor 191 and the mating part 193 reliably confines the bent connector 133 of the wire 131 within the recess 110c, preventing the connector 133 from protruding outside the bottom shell 113 and thus avoiding any adverse effects on normal use. Of course, it is understandable that it is easier to implement a ferromagnetic metal component for the connector 133 and a magnet for the bottom shell 113; for example, a ferromagnetic metal component can be used to cover the outer periphery of the connector 133.

[0074] Of course, in some embodiments, the exposed portion of the connector 133 used to interface with external electronic devices, such as a Type-C interface, is made of a ferromagnetic metal, such as stainless steel. In this embodiment, the interface portion of the connector 133 can be reused as the mating part 193 to simplify the structure of the connector 133.

[0075] Of course, there are other ways to confine the connector 133 within the sink 110c than the one described above. For example, the wall of the sink 110c can have a retaining part to directly engage and confine the connector 133 within the sink 110c. In other words, in this embodiment, the side wall of the sink 110c or both sides of the connector 133 can be provided with a compressible retaining structure. During the process of pressing the connector 133 into the sink 110c, the retaining structure deforms, allowing the connector 133 to be engaged within the sink 110c. This method also ensures that the connector 133 is reliably confined within the sink 110c, and that the connector 133 can be easily removed from the sink 110c when needed, allowing the line 131 to be pulled out from the bottom shell 113.

[0076] When using the desktop fan 100, if the external device has a rechargeable battery and the user needs to charge it, the cable 131 of the retractable cable module 130 can be pulled out from the shell assembly 110 of the desktop fan 100, and the connector 133 can be connected to the external electronic device such as a mobile phone. The desktop fan 100 can then power and charge the external electronic device, eliminating the need for an additional power adapter or power bank and charging cable, thus improving convenience. When the external electronic device does not have a rechargeable battery, the user can still power it using the retractable cable module 130 of the desktop fan 100. When the user no longer needs to power the external electronic device through the desktop fan 100, the cable 131 of the retractable cable module 130 can be stored inside the shell assembly 110, allowing the desktop fan 100 to maintain a relatively simple appearance. Since the outlet 110a is used for the connector 133 to pass through from inside the shell assembly 110 to outside the shell assembly 110, during the assembly of the telescopic cable module 130 and the shell assembly 110, the connector 133 can pass through from inside the shell assembly 110, thereby ensuring the smooth assembly of the telescopic cable module 130 and the shell assembly 110.

[0077] Second Embodiment

[0078] refer to Figure 14 and Figure 15 In the second embodiment of this application, the desktop fan 200 includes a housing assembly 210, a fan 220, and a telescopic cable module 230. The housing assembly 210 is used to support the desktop fan 200 on an external support such as a desktop, and the housing assembly 210 has a cable outlet 210a. The fan 220 is disposed in the housing assembly 210. The fan 220 can be an axial fan. The telescopic cable module 230 is disposed in the housing assembly 210 and includes a cable 231 that can extend and retract relative to the housing assembly 210, and a connector 233 connected to one end of the cable 231. The cable 231 can be housed inside the housing assembly 210 and can be pulled out from the cable outlet 210a to connect to an external electronic device through the connector 233 to supply power to the external electronic device.

[0079] In the second embodiment, the desktop fan 200 may also include a power module 240 disposed within the housing assembly 210, which powers the fan 220. The power module 240 may also include a rechargeable battery, such as a lithium battery. The cable 231 can be wound and stored within the housing assembly 210 to achieve a concealed cable effect, keeping the desktop fan 200 in a relatively simple appearance and avoiding inconvenience caused by the cable 231 during normal use. When the user needs to power external electronic devices such as mobile phones, the cable 231 can be pulled out from the housing assembly 210 and connected to the external electronic device via the connector 233. The power module 240 of the desktop fan 200 then powers these external electronic devices, such as charging mobile phones, tablets, or game controllers, improving ease of use. When the external electronic device does not have a rechargeable battery, the user can also use the retractable cable module 230 of the desktop fan 200 to power the external electronic device. When the user no longer needs to power external electronic devices through the desktop fan 200, the cable 231 can be stored inside the housing component 210, and the desktop fan 200 can still maintain a relatively simple appearance.

[0080] In the second embodiment, the telescopic cable module 230 may also have a digital display to improve ease of use.

[0081] Of course, in the second embodiment, the retractable cord module 230 can also connect to other types of external electronic devices via the connector 233 to power the fan 220. For example, it can connect to external electronic devices such as power banks, emergency power supplies, power adapters, or indoor sockets with integrated discharge ports to power the fan 220, improving ease of use. In the embodiment where the desktop fan 200 includes a power module 240, the retractable cord module 230 can also connect to external electronic devices such as power banks, emergency power supplies, power adapters, or indoor sockets with integrated discharge ports via the connector 233 to charge the power module 240, i.e., to achieve reverse charging function, and indirectly or directly power the fan 120. The power supply circuit of the fan 220 or the reverse charging circuit of the power module 240 are relatively mature existing technologies, and will not be described in detail here.

[0082] Of course, in the second embodiment, the power module 240 can be omitted. In the embodiment where the power module 240 is omitted, when the user needs to use the desktop fan 200, an external power supply can be connected to power the fan 220. In this embodiment using an external power supply, the desktop fan 200 can still be configured to connect to an external electronic device via the connector 233 of the retractable cable module 230 after connecting to an external power supply, and power the external electronic device via the retractable cable module 230. The implementation method can be referred to the first embodiment, and will not be repeated here. The second embodiment is still described using the desktop fan 200 including the power module 240 as an example.

[0083] In the second embodiment, the shell assembly 210 may also include a head shell 211 and a bottom shell 213. The head shell 211 and the bottom shell 213 can be hinged to the opposite ends of the connecting rod 215 one-to-one, as shown in the first embodiment. The fan 220 is disposed in the head shell 211, and the head shell 211 has an air outlet 211a and an air inlet 211b. The telescopic cord module 230 is disposed in the bottom shell 213, and the bottom shell 213 has a cord outlet 210a. In the embodiment where the desktop fan 200 includes a power module 240, the power module 240 may also be disposed in the bottom shell 213. A first circuit board 250 may also be disposed inside the bottom shell 213. The first circuit board 250 integrates the control circuit of the desktop fan 200 and the power management unit, etc. The fan 220, the cord 231 and the power module 240 are electrically connected to the first circuit board 250 respectively. The bottom shell 213 may also be equipped with buttons for controlling the start and stop of the desktop fan 200, a dial for adjusting the speed of the fan 220, etc., which will not be described in detail here.

[0084] The first circuit board 250 inside the bottom shell 213 can also be electrically connected to the fan 220 inside the head shell 211 through a circuit connection. For example, the circuit connection can pass through the bottom shell 213, pass through the hollow connecting rod 215, and connect to the fan 220 inside the head shell 211, thereby providing better protection for the circuit connection and reducing the probability of the circuit connection being accidentally pulled and damaged.

[0085] In other embodiments, the power module 240 may be disposed on the head housing 211, and the telescopic cable module 230 may also be disposed on the head housing 211. Buttons and dials may also be disposed on the head housing 211.

[0086] Similar to the first embodiment, the head shell 211 has a retracted state and an open state relative to the bottom shell 213. In the retracted state, the connecting rod 215 is stacked on the bottom shell 213, and the head shell 211 is stacked on the connecting rod 215. The axis of the head shell 211 and the axis of the bottom shell 213 are substantially coincident. Figure 14 As shown; when in the open state, the connecting rod 215 is set at an angle relative to the bottom shell 213, and the head shell 211 is set at an angle relative to the connecting rod 215. The desktop fan 200 in the open state can be referred to the first embodiment.

[0087] Furthermore, in some embodiments, the head shell 211 and the bottom shell 213 are approximately cylindrical, with the air inlet 211b and the air outlet 211a correspondingly located at opposite ends of the head shell 211. The axis of the fan 220 can be substantially coincident with the axis of the head shell 211 to achieve a relatively better visual effect.

[0088] In the open state, the head shell 211 is supported by the connecting rod 215 and is spaced apart from or overlapped with the bottom shell 213. The axis of the head shell 211 can form an angle with the axis of the bottom shell 213 so that the air outlet 211a can face the user. Exemplarily, in some embodiments, when the bottom shell 213 is laid flat on a horizontal surface, the axis of the bottom shell 213 extends vertically, and the axis of the head shell 211 in the open state can extend horizontally, or be tilted upward or downward relative to the horizontal surface. The user can also adjust the angle of the connecting rod 215 relative to the bottom shell 213 and the angle of the head shell 211 relative to the connecting rod 215 according to usage needs, for example, adjusting the tilt angle of the head shell 211 relative to the table according to the sitting height, thereby improving the convenience and comfort of use.

[0089] To achieve instant positioning of the connecting rod 215 relative to the bottom shell 213 and the head shell 211 relative to the connecting rod 215 when in the open state, the rotational structure of the connecting rod 215 and the bottom shell 213, and the rotational structure of the head shell 211 and the connecting rod 215 can each have appropriate damping, for example, instant positioning can be achieved through a damping shaft, which will not be elaborated here.

[0090] Furthermore, the bottom shell 213 may have a storage groove 213a. When the head shell 211 is folded up, the end where the air inlet 211b is located is stored in the storage groove 213a. The circumferential surface of the head shell 211 is aligned with and flush with the circumferential surface of the bottom shell 213, forming a more integrated appearance and reducing the overall size of the desktop fan 200, making it convenient for storage and transportation. The matching structure of the head shell 211 and the storage groove 213a can be referred to the first embodiment, and will not be described again here.

[0091] Of course, in the second embodiment, the bottom shell 213 may include a support plate 2131 and a support shell 2133 disposed on the support plate 2131. The support plate 2131 and the support shell 2133 form a storage groove 213a and a cavity 213b spaced apart from the storage groove 213a. The telescopic cable module 230 and the power module 240 are disposed in the cavity 213b, and the connecting rod 215 is rotatably connected to the support plate 2131. The support shell 2133 is used to be placed on a support surface such as a desktop, and the support shell 2133 has a cable outlet 210a. The desktop fan 200 may also include a driver 260, such as an electric motor, disposed on the support shell 2133. The output end of the electric motor is linked with the support plate 2131 so that when in the open state, the head shell 211 and the fan 220 are rotated relative to the support shell 2133 through the support plate 2131 and the connecting rod 215 to adjust the orientation of the air outlet 211a. The matching structure can be referred to the first embodiment, and will not be described again here. Of course, driver 260 is not required and can be left as a default.

[0092] The difference from the first embodiment is that the support shell 2133 may include a first shell 21331 and a second shell 21333 connected to the first shell 21331. The first shell 21331 and the second shell 21333 enclose each other to form an outlet 210a. The width of the connector 233 is greater than the width of the outlet 210a. Alternatively, the first shell 21331 and the second shell 21333 have a parting surface, and the two are assembled and enclosed to form the outlet 210a. The width of the outlet 210a can be smaller than the width of the connector 233. For example, the cross-sectional area of ​​the outlet 210a is smaller than the cross-sectional area of ​​the connector 233. The cross-sectional area of ​​the outlet 210a can be comparable to the cross-sectional area of ​​the cable 231, so that the cable 231 can extend and retract into the bottom shell 213. In other words, in this embodiment, the width of the outlet 210a is not required to be greater than or equal to the width of the connector 233. The outlet 210a can be set relatively small to reduce the damage to the overall appearance of the housing assembly 210, while reducing the probability of dust and droplets entering the housing assembly 210 from the outlet 210a. In this embodiment, the first housing 21331 and the second housing 21333 can be assembled by mating, such as by snapping, locking, or bonding, or by connecting with threaded fasteners such as screws to enclose and form the outlet 210a. During the assembly of the telescopic cable module 230 and the housing assembly 210, it is only necessary to pass the cable 231 through the outlet 210a and assemble the first housing 21331 and the second housing 21333 by mating, thereby ensuring the smooth assembly of the telescopic cable module 230 and the housing assembly 210 and improving the assembly efficiency.

[0093] refer to Figure 15 In some embodiments, the first housing 21331 has a first notch Q1, and the second housing 21333 has a second notch Q2. The first notch Q1 and the second notch Q2 are joined to form an outlet 210a. In this embodiment, the first notch Q1 and the second notch Q2 can be arranged in a mirror-symmetric manner about the parting surface to achieve a more harmonious appearance in the housing assembly 210. In other embodiments, the length of the first notch Q1, or the distance between its end and the parting surface, can be greater than the length of the second notch Q2. The second notch Q2 can even be omitted, meaning that the second housing 21333 can form the outlet 210a simply by joining the straight edge of the second housing 21331 with the first notch Q1 at the parting surface, thus facilitating the smooth assembly of the telescopic cable module 230 in the housing assembly 210.

[0094] The desktop fan 200 described above allows users to extend the retractable cable module 230 (231) from the housing 210 of the desktop fan 200 when the external device has a rechargeable battery and the user needs to charge it. The connector 233 can then be connected to the external electronic device, such as a mobile phone, via the desktop fan 200. This eliminates the need for an additional power adapter or power bank and charging cable, improving convenience. Even when the external electronic device does not have a rechargeable battery, the user can still power it using the retractable cable module 230. When the user no longer needs to power the external electronic device via the desktop fan 200, the cable 231 of the retractable cable module 230 can be stored back inside the housing 210, maintaining a clean and simple appearance for the desktop fan 200. Since the width of the connector 233 is greater than the width of the outlet 210a, the first housing 21331 and the second housing together form the outlet 210a. During the assembly of the telescopic cable module 230 and the housing assembly 210, the cable 231 can be inserted through the outlet 210a between the first housing 21331 and the second housing 21333. Then, the first housing 21331 and the second housing 21333 are assembled and fixed, which ensures the smooth assembly of the telescopic cable module 230 and the housing assembly 210.

[0095] Of course, in the second embodiment, the first housing 21331 and the second housing 21333 can also be enclosed to form a recess 210c communicating with the cable outlet 210a. The cable outlet 210a is located at the bottom of the recess 210c, and the cable 231 can be bent so that the connector 233 is confined in the recess 210c. For example, the desktop fan 200 may include a magnetic member 271, which is connected to the housing assembly 210 and is disposed corresponding to the bottom of the recess 210c. The connector 233 has a mating member 273, which is used to magnetically engage with the magnetic member 271 to attract the connector 233 to the bottom of the recess 210c. Furthermore, one surface of the connector 233 in the thickness direction can be attached to the bottom of the recess 210c. This surface has a relatively large area, and the depth of the recess 210c does not need to be too large, so as to avoid having too much impact on the overall appearance of the housing assembly 210.

[0096] One of the magnetic attractor 271 and the mating part 273 is a magnet, and the other is a magnet or a ferromagnetic metal such as iron, cobalt, nickel, or their alloys. The magnetic attraction between the magnetic attractor 271 and the mating part 273 reliably confines the bent connector 233 within the recess 210c, preventing it from dangling outside the housing assembly 210 and negatively impacting normal use. It is understood that it is easier to implement a ferromagnetic metal connector 233 and a magnet in the housing assembly 210; for example, a ferromagnetic metal can be used to cover the outer periphery of the connector 233. In some embodiments, the exposed portion of the connector 233 used for interfacing with external electronic devices, such as a Type-C interface, is made of a ferromagnetic metal, such as stainless steel. In this embodiment, the interface portion of the connector 233 can be reused as the mating part to simplify the structure of the connector 233.

[0097] Of course, there are other ways to limit the connector 233 to the sink 210c. For example, the wall of the sink 210c may have a retaining part, which can be used to directly lock the connector 233 into the sink 210c. The structure and function of the sink 210c can be referred to the first embodiment, and will not be repeated here.

[0098] For details on other structures of the desktop fan 200, such as the retractable cord module 230, please refer to the first embodiment of this application. In other words, the retractable cord module 230 of the first embodiment can be applied to the second embodiment, and the description of the retractable cord module 230 in the first embodiment can be directly used in the second embodiment, and will not be repeated here.

[0099] Third Embodiment

[0100] refer to Figure 16 and Figure 17 In the third embodiment of this application, the shell assembly 310 of the desktop fan 300 may further include a suspension member 390 movably disposed on the bottom shell 313. For example, a receiving groove 313a is provided on the side of the bottom shell 313 opposite to the head shell 311, or on the side of the bottom shell 313 for placement on the support surface. The suspension member 390 is rotatably connected to the bottom shell 313 and can be received in the receiving groove 313a or flipped out of the receiving groove 313a. When the suspension member 390 is received in the receiving groove 313a, such as Figure 16 As shown, the suspension member 390 does not protrude from the side of the bottom shell 313 opposite to the head shell 311, so as to ensure that the bottom shell 313 can be stably supported on the support surface; after the suspension member 390 flips out of the receiving groove 313a, as Figure 17 As shown, the desktop fan 300 can be suspended to external hooks, ropes, or other locations via the hook structure of the hanging component 390, making it convenient to store the desktop fan 300 or expand the usage scenarios of the desktop fan 300 in the open state, thus improving the ease of use.

[0101] In some embodiments, the bottom shell 313 may also have a hanging groove 313b communicating with the receiving groove 313a. The hanging groove 313b has an inwardly recessed structure and is used to hang it on a wall or other support. Hooks or nails for hanging can be provided at these positions to reliably hang the desktop fan 300 at these positions, which facilitates the storage of the desktop fan 300 or expands the usage scenarios of the desktop fan 300 in the open state and improves the convenience of use.

[0102] For details of other structures of the desktop fan 300 in the third embodiment, such as the telescopic cable module, head shell 311, and bottom shell 313, please refer to the first embodiment of this application. In other words, other structures of the telescopic cable module 130, head shell 111, and bottom shell 113 in the first embodiment can be applied to the third embodiment, and will not be described again here.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
