[0040] As shown in Figures 1 to 7 The utility model provides a kind of fan device, including fan assembly 100 and clamping assembly 200.Wherein, fan assembly 100 includes driving member, shell 110 and fan blade 120, fan blade 120 is installed to the output shaft outer wall of driving member, fan blade 120 and driving member are all installed in shell 110, shell 110 is provided with openwork structure 111, airflow generated by the rotation of fan blade 120 around shaft can pass through openwork structure 111;Clamping assembly 200 is installed to shell 110, clamping assembly 200 includes pipe clamp 210, pipe clamp 210 can be elastically deformed, pipe clamp 210 is C-shaped, the section enclosed by pipe clamp 210 is oval, including major axis and minor axis, the clamping direction of pipe clamp 210 is parallel to the straight line where minor axis is located.

[0041] Exemplarily, driving member is fixed in shell 110, the outer wall of the output shaft of driving member is provided with a plurality of fan blades 120, and the openwork structure 111 of the shell 110 forms an air inlet and an air outlet. When the driving member is driven, the fan blades 120 rotate with the output shaft, agitate the air to form an air flow, and the direction of the air flow is consistent with the axial direction of the output shaft. In this way, the blowing function is realized.

[0042] Fan assembly 100 can be fixed on support rod through pipe clamp 210, which enriches its use scene, and does not need plane support, thereby adjusting the distance between fan assembly 100 and user. Further, the inside of pipe clamp 210 is enclosed into pipe space, the axial section of pipe space is oval, including major axis and minor axis, pipe clamp 210 forms an opening on one side in the circumferential direction, and the support rod can be inserted into the pipe space along the radial direction of the support rod from the opening. During the insertion process, the pipe clamp 210 can be elastically deformed and tighten the support rod, and the fixation is completed. The oval pipe space can adapt to support rods with different shaft diameters, as long as R1

[0043] Optionally, the pipe holding clamp 210 comprises a sleeving part 211 and a guiding part 212. The sleeving part 211 is in a C shape, and the side wall forms an opening. The guiding part 212 comprises two flaps, which are arranged in the first direction and connected to the two outer side surfaces of the opening of the sleeving part 211, respectively. The distance between the two flaps gradually increases in the direction away from the sleeving part 211 along the long axis. The straight line where the short axis is located is parallel to the first direction. In this way, the guiding part 212 can make the opening of the sleeving part 211 more easily spread along the side wall profile of the support rod when the sleeving part 211 is sleeved on the support rod, so that the support rod enters the sleeving part 211.

[0044] Optionally, the outer peripheral wall of the pipe holding clamp 210 is provided with a reinforcing rib 213, which extends along the circumference of the pipe holding clamp 210. The reinforcing rib 213 is used to maintain the opening degree of the pipe holding clamp 210, thereby maintaining the connection reliability of the pipe holding clamp 210 and the support rod.

[0045] Optionally, the inner peripheral wall of the pipe holding clamp 210 is provided with an anti-skid structure 214.

[0046] Optionally, the inner peripheral wall of the pipe holding clamp 210 is provided with an anti-skid pad made of rubber. When the pipe holding clamp 210 is sleeved and clamped on the support rod, the anti-skid pad can be elastically deformed to further fill the gap between the sleeving part 211 of the pipe holding clamp 210 and the support rod. In addition, the anti-skid pad has a large friction coefficient, which can limit the movement of the pipe holding clamp 210 relative to the support rod along the axial direction of the support rod, thereby maintaining the relative position of the fan device and the support rod.

[0047] Optionally, the pipe holding clamp 210 is installed on the housing 110 through a magnetic attraction structure. In this way, the pipe holding clamp 210 and the housing 110 are designed in a split type, which makes the fan device applicable to more scenarios. During use, the pipe holding clamp 210 has been assembled with the support rod, but when the fan assembly 100 needs to be maintained or charged, the fan assembly 100 and the pipe holding clamp 210 can be separated directly, which can reduce the disassembly and assembly times between the pipe holding clamp 210 and the support rod, avoid the gradual relaxation of the pipe holding clamp 210 in repeated opening and closing, and realize the simple disassembly and assembly between the fan assembly 100 and the pipe holding clamp 210, which is convenient to operate.

[0048] Further, since the magnetic force structure mainly relies on the magnetic force generated between the magnetic parts, it is relatively simple in structure compared with other mechanical connection structures that need to be limited by the engagement between structures. During use, the fan assembly 100 and the pipe holding clamp 210 only need to be close to each other, without the need for alignment. In addition, when the connection between the two is loose, the magnetic attraction part can be replaced.

[0049] Optionally, the pipe holding clamp 210 is fixed with the shell 110 through the connecting seat 220, the connecting seat 220 is installed with a first magnetic attraction member, the shell 110 is installed with a second magnetic attraction member, and the first magnetic attraction member and the second magnetic attraction member can be attracted to each other.

[0050] Optionally, the pipe holding clamp 210 can rotate relative to the fan assembly 100 around the first axis, and the first axis is perpendicular to the axis direction of the output shaft of the driving member.

[0051] In this way, when the pipe holding clamp 210 is fixed with the support rod, the fan assembly 100 can rotate relative to the pipe holding clamp 210 around the first axis to realize the swing action, thereby completing the adjustment of the blowing angle. When it is necessary to adjust the blowing angle of the fan assembly 100, the pipe holding clamp 210 is rotated relative to the support rod, thereby avoiding the problem that the connection between the pipe holding clamp 210 and the support rod is loose.

[0052] Optionally, the clamping assembly 200 further comprises a connecting seat 220, the connecting seat 220 is detachably installed on the shell 110, and the pipe holding clamp 210 is hinged with the connecting seat 220 around the first axis.

[0053] Optionally, one of the connecting seat 220 and the shell 110 is provided with a limiting protrusion 221, and the other is provided with a limiting slot 112 corresponding to the limiting protrusion 221.

[0054] For example, in this embodiment, the limiting protrusion 221 is arranged on the connecting seat 220, and the limiting slot 112 is arranged on the shell 110. In this way, the insertion of the limiting slot 112 and the limiting protrusion 221 can correct and limit the relative position of the connecting seat 220 and the shell 110.

[0055] Further, the limiting protrusion 221 is in an elliptical shape, and the limiting slot 112 is in a corresponding elliptical shape, so that the insertion of the limiting protrusion 221 and the limiting slot 112 can play a foolproof role.

[0056] Optionally, one of the connecting seat 220 and the pipe holding clamp 210 is provided with a hinged protrusion 222, and the other is provided with a U-shaped slot 215, the hinged protrusion 222 is inserted into the U-shaped slot 215 and connected through a rotating shaft, and the axis of the rotating shaft is parallel to the first axis.

[0057] For example, in this embodiment, the hinged protrusion 222 is arranged on the connecting seat 220, the U-shaped slot 215 is formed in the pipe holding clamp 210, the hinged protrusion 222 is inserted into the U-shaped slot 215 and can rotate around the rotating shaft in the U-shaped slot 215, and the opposite two side walls of the U-shaped slot 215 in the axis direction of the rotating shaft can limit the hinged protrusion 222, thereby keeping the relative stability between the connecting seat 220 and the pipe holding clamp 210.

[0058] Further, the shaft is connected with a damping member, the damping member can keep the fan assembly 100 and the connecting seat 220 in a preset position, and relative rotation is not prone to occurring.

[0059] Optionally, the clamping assembly 200 is located on the side of the driving member away from the fan blade 120 along the axial direction of the output shaft of the driving member.

[0060] In addition, the above are only preferred embodiments of the present application and the technical principles applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the scope of the present application.
