[0034] The utility model provides a desktop fan.

[0035] In the embodiment of the present utility model, Figures 1 to 8 As shown, the desktop fan includes a housing 10 , a fan assembly 20 and a support frame 30 .

[0036] Specifically, the housing 10 is provided with an air inlet 12 , an air outlet 11 and an air duct 13 connected between the air inlet 12 and the air outlet 11 ; the fan assembly 20 is rotatably installed in the air duct 13 and is arranged toward the air outlet 11 .

[0037] The support frame 30 has a connecting section 31 and a hanging section. The connecting section 31 is rotatably mounted on the shell 10. The hanging section is connected to the end of the connecting section 31 away from the shell 10. The support frame 30 has a supporting state and a hanging state. In the supporting state, the connecting section 31 and the back of the shell 10 are set at an acute angle. In the hanging state, the support frame 30 is attached to the back of the shell 10, and the hanging section is located at the upper position of the shell 10 to be used as a hanging ring.

[0038] The air inlet 12 and the air outlet 11 are provided on opposite sides of the housing 10, and the air duct 13 is located between the air inlet 12 and the air outlet 11. In this embodiment, the air inlet 12 and the air outlet 11 are both provided with mesh covers.

[0039] In actual use, when the user needs to place the desktop fan on a desktop for use, the support frame 30 can be rotated to the supporting state, so that the housing 10 is supported on the desktop for use through the support frame 30. When the user needs to hang the desktop fan for use, the support frame 30 can be rotated to the hanging state, so that the support frame 30 can be used as a hanging ring, so that the desktop fan can be hung on the wall for use through the support frame 30.

[0040] It is worth noting that the support frame 30 also has a storage state, in which the support frame 30 is attached to the back of the housing 10, and the hanging section is located at the lower part of the housing 10. That is, the user can rotate the support frame 30 to the storage state for storage.

[0041] The technical solution of the present invention is to provide an air outlet 11, an air inlet 12 and an air duct 13 connected between the air outlet 11 and the air inlet 12 on the housing 10, install the fan assembly 20 in the air duct 13 and arrange it toward the air outlet 11, and the support frame 30 has a connecting section 31 and a hanging section that are connected to each other. The connecting section 31 is rotatably connected to the housing 10. The support frame 30 has a supporting state and a hanging state. In the supporting state, the support frame 30 is arranged at an acute angle to the back of the housing 10. In the hanging state, the support frame 30 is attached to the back of the housing 10, and the hanging section is located at the upper part of the housing 10 for use with a hanging ring. In this way, when the user needs to place the desktop fan on the desktop for use, the support frame 30 can be rotated to the supporting position to support the housing 10 on the desktop for use. When the user needs to hang the desktop fan for use, the support frame 30 can be rotated to the hanging state so that the support frame 30 can be used as a hanging ring. In this way, the fan can be hung on a wall or other places for use through the support frame 30. This configuration makes the desktop fan suitable for different scenarios, in other words, effectively expanding the usage scenarios of the desktop fan.

[0042] In some embodiments, the connection position between the connecting section 31 and the housing 10 is located near the upper portion of the housing 10. In the hanging state, the hanging section is exposed from the upper side of the housing 10. The hanging section extends from the upper side of the housing 10, so that when the user needs to hang the desktop fan on the wall for use, the hanging section extending from the upper side of the housing is convenient for the user to see, that is, the desktop fan can be easily hung on the wall for use.

[0043] In some embodiments, a groove 321 is provided on the inner side of the hanging segment. The groove 321 is provided between the two ends of the hanging segment and passes through the opposite sides of the hanging segment.

[0044] Specifically, the groove 321 is located in the middle of the hanging section. In daily life, a desktop fan is usually hung using a hook. When a user needs to hang a desktop fan on a wall for use, they can hook the hook into the corresponding position of the groove 321. This prevents the fan from tilting and helps improve the hanging stability of the desktop fan. Of course, in other embodiments, the hanging section may not be provided with the groove 321.

[0045] In some embodiments, the support frame 30 has two connecting sections 31, which are rotatably connected to opposite sides of the housing 10, and the hanging section is connected between the two connecting sections 31. In other embodiments, the support frame 30 has only one connecting section 31.

[0046] Furthermore, the connecting section 31 is provided with a limiting portion 311, and the ear portion 14 is provided with an assembly hole 141. A limiting structure 60 is disposed within the assembly hole 141. The limiting portion 311 is rotatably mounted within the assembly hole 141, and the limiting portion 311 and the limiting structure 60 cooperate in a limiting manner. Specifically, the limiting portion 311 is located at the end of the connecting section 31 away from the hanging section. Rotating the limiting portion 311 within the assembly hole 141 allows the connecting section 31 to rotate stably while also limiting the support and hanging states of the support frame 30. This arrangement helps improve the support and hanging stability of the desktop fan.

[0047] Furthermore, the limiting portion 311 is provided with a through hole 312, which passes through the inner side surface of the limiting portion 311, and the wall of the through hole 312 is provided with a plurality of slots 313, and the plurality of slots 313 are distributed at intervals along the circumference of the wall of the through hole 312. The limiting structure 60 includes a limiting member 61 and a protrusion 62 protruding from the circumference of the limiting member 61. The slot 313 has two first wall surfaces distributed at intervals along the rotation direction, and the protrusion 62 has two first surfaces distributed at intervals along the rotation direction. When the protrusion 62 is inserted into the slot 313, the two first wall surfaces and the two first surfaces are in one-to-one contact with each other, and the spacing between the two first wall surfaces gradually increases in the direction away from the wall of the through hole 312, and the spacing between the two first surfaces gradually decreases in the direction away from the limiting member 61.

[0048] Specifically, when the user rotates the support frame 30, the surface of the latch 62 and the wall of the slot 313 can act as a guide. Even if the latch 62 does not disengage from the slot 313, the latch 62 can still move toward the slot 313 in the direction of rotation under the force of rotation. In this way, the arrangement of the latch 62 allows the latch 62 to provide a certain amount of damping when the user rotates the support frame 30. In this way, when the user does not apply a certain pulling force or pushing force to the support frame 30, the latch 62 will not disengage from the slot 313, thereby stably restricting the support frame 30 to a supported state or a suspended state. The shape of the slot 313 can be trapezoidal. Similarly, the latch 62 is configured as a trapezoidal structure. When the slot 313 is spherical, the two opposing walls of the spherical slot 313 are the two first walls. Similarly, the latch 62 is also spherical, and the two opposing surfaces of the spherical latch 62 are the two first surfaces.

[0049] In some embodiments, a plurality of latching protrusions 62 are protruded from the sidewall of the limiting member 61 . The plurality of latching protrusions 62 are distributed at intervals along the circumference of the limiting member 61 , and the number of the latching protrusions 62 is less than the number of the latching slots 313 .

[0050] Specifically, there are at least two latching protrusions 62, and the number of latching slots 313 needs to be greater than the number of latching protrusions 62, that is, the number of latching slots 313 is at least three, so that the connecting section 31 can stably rotate in the assembly hole 141. In this way, by engaging multiple latching protrusions 62 with the latching slots 313, the user needs to apply more pulling force or pushing force when rotating the support frame 30. In other words, this can increase the rotational damping of the support frame 30 and can more stably restrict the support frame 30 to a supporting state or a hanging state. Exemplarily, the number of latching protrusions 62 can be two, three, four, etc., and the corresponding number of latching slots 313 is at least one more than the number of latching protrusions 62. Of course, in other embodiments, only one latching protrusion 62 is provided.

[0051] In some embodiments, the desktop fan further includes a power module 50, which is disposed within the housing 10 and electrically connected to the fan assembly 20. The power module 50 is used to provide electrical energy to the fan assembly 20, enabling the desktop fan to operate without an external power source, thereby enhancing the user experience. Optionally, the power module 50 is rechargeable. Of course, in other embodiments, the desktop fan may not be provided with a power module 50.

[0052] In some embodiments, the air outlet 11 is arranged on the front side of the shell 10, and the air inlet 12 is arranged on the rear side of the shell 10. The desktop fan also includes a display screen 40, which is arranged on the front side of the shell 10 and is electrically connected to the power module 50.

[0053] Specifically, the display screen 40 and the air outlet 11 are both provided on the front side of the housing 10, and the display screen 40 is located on the lower side of the air outlet 11. The display screen 40 can be used to display the remaining power of the power module 50, so that the user can clearly know the current power of the power module 50. The display screen 40 can also be used to display the rotation speed of the fan assembly 20. For example, the display screen 40 displays weak, medium, strong, etc. according to the rotation speed of the fan assembly 20, and can also be set to display level one, level two, level three, etc. The specific setting can be made according to the actual situation. Such a setting is conducive to improving the user experience. It is worth noting that the design of the present application is not limited to this. In other embodiments, the desktop fan is provided with an indicator light, and the indicator light is electrically connected to the fan assembly 20. The indicator light flashes to provide prompts to the user.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, within the inventive concept of the present invention, are included in the patent protection scope of the present invention.
