[0038] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0039] like Figures 1 to 14 As shown, the present application provides a circulation fan, which includes a base 10, a driving mechanism 20 and a fan body 30, wherein the base 10 includes a seat plate 12 and a support rod 11 arranged on the seat plate 12, the driving mechanism 20 includes a telescopic rod 21 and a support frame 22 arranged above the telescopic rod 21, the fan body 30 is connected to the support frame 22 away from the telescopic rod 21, and the telescopic rod 21 is sleeved in the support rod 11 for adjusting the longitudinal height of the fan body 30 so that the fan body 30 can stay at a preset height according to user needs.

[0040] In this embodiment, the driving mechanism 20 also includes a transverse motor 24, which is installed on the telescopic rod 21. Its output end is transmission-connected to the support frame 22 for driving the fan body 30 on the support frame 22 to swing left and right. The structure is simple but practical.

[0041] Specifically, the support rod 11 is provided with a support rod through-hole (not shown in the figure), the shape and size of the support rod through-hole are adapted to the shape and size of the telescopic rod 21, so that the telescopic rod 21 can be just placed in the support rod through-hole and fixed by the adjustment device on the outside of the support rod 11.

[0042] In an optional embodiment, the telescopic rod 21 includes a telescopic rod body and a transverse motor fixing portion 241 provided at an upper end of the telescopic rod body, and the transverse motor 24 is mounted on the transverse motor fixing portion 241 .

[0043] Specifically, the transverse motor fixing part 241 includes a locking shell 2411 and a fixed shell 2412. The telescopic rod body is located at one end outside the support rod 11 and is provided with a telescopic rod fixed end 211. The locking shell 2411 is locked on the telescopic rod fixed end 211 by screws, and then the fixed shell 2412 is installed on the locking shell 2411. The fixed shell 2412 is used to fix the transverse motor 24.

[0044] In an optional embodiment, a motor fixing groove (not shown in the figure) is provided on the transverse motor fixing portion 241, wherein the shape and size of the motor fixing groove are adapted to the shape and size of the transverse motor 24, so that the transverse motor 24 can be installed in the motor fixing groove, which not only facilitates the installation of the transverse motor 24, but also makes the structure of the telescopic rod 21 appear more compact and the design more reasonable.

[0045] In an optional embodiment, the telescopic rod 21 also includes a transverse motor cover 244 and a first bearing 242, wherein the output end of the transverse motor 24 is fixed to the transverse motor cover 244 through the first bearing 242, and the support frame 22 is arranged on the outside of the transverse motor cover 244, which can not only improve the transmission stability of the transverse motor 24, but also reduce the noise generated by the transverse motor 24 during operation.

[0046] Specifically, the transverse motor housing 244 includes a housing body 2441 and a housing cover 2442. The housing cover 2442 is mounted on the housing body 2441, and the housing body 2441 is mounted in the fixed housing 2412. A first bearing mounting portion (not shown) is provided on the housing body 2441, and the first bearing 242 is fixed to the first bearing mounting portion. The output end of the transverse motor 24 passes through the first bearing 242 and the housing cover 2442 in sequence before being connected to the support frame 22. This not only increases the longitudinal transmission distance of the transverse motor 24, but also ensures the stability of the transmission of the transverse motor 24 and prevents the output of noise during the transmission of the transverse motor 24.

[0047] In an optional embodiment, the drive mechanism 20 further includes an adapter 243, which is fixed to the outer ring of the first bearing 242. The inner ring of the first bearing 242 is mounted on the first bearing mounting portion. In this embodiment, one end of the adapter 243 is connected to the support frame 22, and the other end of the adapter 243 is connected to the transverse motor 24.

[0048] Specifically, the cover body 2441 can be processed into a solid structure to ensure the strength of the cover body 2441 at the first bearing mounting position. The two ends of the adapter 243 are respectively provided with a torque transmission hole and a torque output shaft, wherein the torque transmission hole is used to connect with the output shaft of the horizontal motor 24, and the torque output shaft is connected to the support frame 22 to drive the fan body 30 on the support frame 22 to swing left and right.

[0049] After adopting the above technical solution, since the telescopic rod body, locking shell 2411, fixed shell 2412, cover body 2441 and cover cover 2442 are all designed to be split, and then the telescopic rod body, locking shell 2411, fixed shell 2412, cover body 2441 and cover cover 2442 are assembled together, this not only facilitates the molding design of the telescopic rod body, locking shell 2411, fixed shell 2412, cover body 2441 and cover cover 2442, but also allows different materials to be selected for the telescopic rod body, locking shell 2411, fixed shell 2412, cover body 2441 and cover cover 2442 according to the strength and hardness requirements of the parts where the telescopic rod body, locking shell 2411, fixed shell 2412, cover body 2441 and cover cover 2442 are used, thereby saving manufacturing costs.

[0050] In an optional embodiment, the support frame 22 is in a U-shaped structure, one end of which is connected to the adapter 243 and the other end of which is connected to the fan body 30 .

[0051] Specifically, the distance between the two ends of the support frame 22 is greater than the diameter of the fan body 30, so that the fan body 30 can be installed in the recess of the support frame 22. This not only facilitates the installation and disassembly of the fan body 30, but also ensures the strength of the support frame 22, that is, the entire fan body 30 can be accommodated in the recess of the support frame 22, and the center of the rear shell of the fan body 30 is connected to one end of the support frame 22, and the lower end of the fan body 30 can be fitted on the side of the other end of the support frame 22.

[0052] In an optional embodiment, a longitudinal motor 24 is provided between the support frame 22 and the fan body 30, wherein the longitudinal motor 24 is fixed on the support frame 22, and the output end of the longitudinal motor 24 is transmission-connected to the fan body 30 so that the fan body 30 can swing up and down on the support frame 22.

[0053] Specifically, a mounting frame 23 is provided between the support frame 22 and the fan body 30, wherein the mounting frame 23 is fixed at the other end of the support frame 22, the fan body 30 is rotatably connected to the mounting frame 23, and the longitudinal motor 24 is installed in the mounting frame 23 and drives the fan body 30 to swing in the longitudinal direction through the gear rack.

[0054] After adopting the above technical solution, since the longitudinal motor 24 is installed on the mounting frame 23 and is connected to the fan body 30 through a gear rack, not only is the structure simple, but a long-distance transmission connection can also be achieved, so that the longitudinal motor 24 can drive the fan body 30 to swing in the longitudinal direction through the gear rack, thereby realizing the adjustment of the circulating fan air supply angle, thereby meeting the user's requirements for the circulating fan air supply angle.

[0055] In an optional embodiment, the mounting bracket 23 includes a first mounting bracket 231 and a second mounting bracket 232, wherein the longitudinal motor 24 is fixed to the second mounting bracket 231, the fan body 30 is rotatably connected to the second mounting bracket 232, the second mounting bracket 232 is fixedly connected to the first mounting bracket 231, and the first mounting bracket 231 is installed in the fan body 30. When the longitudinal motor 24 is in operation, the longitudinal motor 24 drives the fan body 30 to rotate relative to the second mounting bracket 231 via the gear rack, thereby allowing the fan body 30 to rotate relative to the mounting bracket 23, so that the user can adjust the air supply angle of the circulation fan.

[0056] Specifically, the second mounting bracket 232 has a U-shaped structure and can be formed in one step through a bending process. This not only ensures the strength of the second mounting bracket 232 but also reduces the manufacturing cost of the second mounting bracket 232. In this embodiment, the ends of the second mounting bracket 232 slightly protrude outward so that the fan body 30 can be mounted therebetween.

[0057] In an optional embodiment, fan body rotating shafts are provided on both sides of the second mounting bracket 232 so that the fan body 30 can be rotatably mounted on the fan body rotating shafts.

[0058] In an optional embodiment, the driving mechanism 20 further includes a transmission assembly 26 composed of a gear rack. The longitudinal motor 24 drives the fan body 30 to swing relative to the mounting bracket 23 through the transmission assembly 26 to meet the user's requirements for the air supply angle of the circulation fan.

[0059] Specifically, the transmission assembly 26 includes a transmission rack 263, a driving wheel 261 installed on the longitudinal motor 24, and a driven wheel 262 installed on the fan body 30, wherein the driving wheel 261 and the driven wheel 262 are both connected to the transmission rack 263, and the driving wheel 261 and the driven wheel 262 are respectively arranged at opposite ends of the transmission rack 263. This is not only conducive to the reasonable design of the internal space of the mounting frame 23, and facilitates the installation of the longitudinal motor 24 and the fan body 30 in a mounting frame 23 with a relatively small space, but also ensures the transmission stability of the transmission assembly 26.

[0060] In an optional embodiment, a rack guide portion is provided on the first mounting frame 231, and the transmission rack 263 can be movably mounted on the rack guide portion to limit the moving direction of the transmission rack 263, so that the longitudinal motor 24 can drive the transmission rack 263 to move through the driven wheel 262, and then drive the driven wheel 262 to rotate through the transmission rack 263, so that the driven wheel 262 can drive the fan body 30 to rotate.

[0061] In an optional embodiment, the rack guide portion is a guide rail 2311 arranged on the first mounting frame 231, wherein a guide rail groove (not shown in the figure) is provided on the transmission rack 263 so that the transmission rack 263 can be movably engaged in the guide rail 2311 through the guide rail groove.

[0062] Specifically, the guide rail 2311 has a T-shaped structure, and the shape of the guide rail groove is adapted to the shape of the guide rail 2311, thereby facilitating the installation of the guide rail 2311 and preventing the guide rail 2311 from being separated from the guide rail groove, especially when the guide rail 2311 is installed on the vertical end face of the first mounting frame 231.

[0063] In an optional embodiment, a torque hole (not shown in the figure) is provided on the driven wheel 262, and a receiving groove 311 with a height greater than the first mounting bracket 231 is provided on the fan body 30. Torque shafts 312 are provided on both sides of the receiving groove 311. After the first mounting bracket 231 is installed in the receiving groove 311, the driven wheel 262 is sleeved in the torque shaft 312 through the torque hole, so that when the longitudinal motor 24 is working, it can drive the driven wheel 262 through the transmission rack 263 to drive the torque shaft 312 to rotate, so that the user can adjust the air supply angle of the circulation fan.

[0064] Specifically, the torque shaft 312 may include a first torque shaft and a second torque shaft. The shape and structure of the first torque shaft may be the same as or different from the shape and structure of the second torque shaft. In this embodiment, the shape and structure of the first torque shaft may be different from the shape and structure of the second torque shaft. The outer side of the first torque shaft may have a stepped or square structure, for example, so that the driven pulley 262 can transmit torque from the driven pulley 262 to the first torque shaft through the torque hole. The second torque shaft is cylindrical, solely to enhance support for the fan body 30 and ensure rotational stability of the fan body 30.

[0065] In an optional embodiment, the first mounting frame 231 has a first open end facing the support frame 22, wherein the support frame 22 is provided with a support frame cover 221, and the support frame cover 221 is movably mounted in the first open end.

[0066] Specifically, the shape and size of the support frame cover 221 are adapted to the shape and size of the first open end. Since the height of the accommodating groove 311 is greater than the height of the first mounting frame 231, when the first mounting frame 231 is installed in the accommodating groove 311, when the longitudinal motor 24 is working, the support frame cover 221 and the first mounting frame 231 can move in the accommodating groove 311, so that the fan body 30 can rotate relative to the first mounting frame 231.

[0067] In an optional embodiment, the support frame cover 221 is movably mounted in the first open end via an elastic member to ensure the relative position between the support frame cover 221 and the receiving groove 311 .

[0068] In an optional embodiment, a first snap-fitting portion (not shown in the figure) is provided on the first open end, and a second snap-fitting portion 2211 is provided on the support frame cover, wherein the first snap-fitting portion is snap-fitted to the second snap-fitting portion 2211 so that the support frame cover 221 can move along the first snap-fitting portion through the second snap-fitting portion 2211.

[0069] In an optional embodiment, a mounting frame cover 233 is further provided on the mounting frame 23, wherein a cover groove 2212 is provided on the support frame cover 221, and the mounting frame cover 233 can be movably installed in the cover groove 2212, one end of the elastic member 223 abuts against the support frame cover 221, and the other end of the elastic member 223 abuts against the mounting frame cover 233 to ensure that the mounting frame 23 always remains sealed from the outside, while allowing the support frame cover 221 to move relative to the mounting frame cover 233 through the cover groove 2212.

[0070] Specifically, a first guide rail portion 2331 is provided on the mounting frame cover 233, and a first guide groove portion is provided in the cover groove 2212. The first guide rail portion 2331 is cooperatively connected with the first guide groove portion so that the mounting frame cover 233 can move along the first guide groove portion through the first guide rail portion 2331. At the same time, the mounting frame cover 233 can always maintain a closed state under the elastic force of the elastic member 223.

[0071] In an optional embodiment, the second snap-fitting portion 2211 is arranged at the lower end of the cover groove 221 to ensure that the mounting frame cover 233 can be reasonably designed, that is, the cover groove 221 on the support frame cover 221 is used to accommodate the mounting frame cover 233, and the second snap-fitting portion 2211 at its lower end is used for guiding.

[0072] In an optional embodiment, a positioning platform (not shown in the figure) is provided at one end of the second mounting frame 232 facing away from the U-shaped slot, and a positioning slot is provided on the first mounting frame 231. The position of the positioning platform corresponds to the position of the positioning slot, so that the second mounting frame 232 can be installed on the first mounting frame 231 through the matching connection between the positioning platform and the positioning slot, thereby playing a positioning role.

[0073] Specifically, there are two positioning platforms, and the two positioning platforms are symmetrically arranged on the second mounting frame 232 with the central axis of the bottom end of the second mounting frame 232. In this embodiment, the second mounting frame 232 is also provided with a plurality of fixing screw holes, and the plurality of fixing screw holes are arranged between the two positioning platforms. After the second mounting frame 232 is installed on the first mounting frame 231 through the cooperation of the positioning platform and the positioning groove, the screws are passed through the plurality of fixing screw holes and are fastened to the first mounting frame 231.

[0074] In an optional embodiment, the fan body 30 includes a front shell 32, a rear shell 31, fan blades 33 and a fan motor 34 for driving the fan blades 31 to rotate, wherein the front shell 32 is joined to the rear shell 32 and forms an accommodating space, the fan blades 33 are arranged in the accommodating space, and the fan motor 34 is fixed on the rear shell 31.

[0075] Specifically, a motor mounting platform 313 is protruding from the bottom end of the accommodating groove 311, wherein the fan motor 34 is mounted on the motor mounting platform 313, and the output end of the fan motor 34 passes through the motor mounting platform 313 and is connected to the fan blade 33. This not only reduces the need to add a bracket to the circulation fan for fixing the fan motor 34, but also ensures the hardness of the accommodating groove 311 in fixing the fan motor 34.

[0076] In an optional embodiment, the first torque shaft and the second torque shaft are arranged on both sides near the motor mounting platform 313 to ensure that the fan body rotating shaft on both sides of the second mounting frame 232 can bear the gravity of the entire fan body 30 through the first torque shaft and the second torque shaft, and drive the fan body 30 to swing up and down.

[0077] In an optional embodiment, the first mounting frame 231 is provided with a second open end at one end facing the fan motor 34, and the position of the second open end corresponds to the position of the fan motor 34, so that the fan motor can be arranged in the second open end, that is, after the fan motor 34 is installed on the motor mounting platform 313, its rear end passes through the second open end and is located in the first mounting frame 231, so that the structure of the fan body 30 appears more compact.

[0078] In an optional embodiment, the inner side of the support frame 22 is provided with a support frame through groove 222 running through both ends, which is used to arrange the cables of the fan body 34 and the longitudinal motor 24, so as to avoid the cables of the circulation fan being exposed outside the circulation fan and affecting the aesthetics of the circulation fan, and is also beneficial to the cable arrangement of the circulation fan.

[0079] Specifically, the support frame 22 includes a first shell and a second shell, wherein the first shell and the second shell are interlocked to form the above-mentioned support frame through groove, which not only facilitates the manufacturing and forming of the support frame 22, but also facilitates the assembly of the support frame 22, thereby reducing the processing cost of the support frame 22.
