[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0048] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0049] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0050] like Figures 1 to 25 As shown, the present application provides a circulation fan, which includes a body 10 and a base 20, wherein a support assembly 30 is provided on the base 20, and the body 10 is mounted on an end of the support assembly 30 away from the base 20. In this embodiment, the body 10 includes fan blades 11, a front shell 12, a rear shell 13, and a fan motor 14 for driving the fan blades 11 to rotate. The front shell 12 and the rear shell 13 are connected to form an accommodating space. The fan blades 11 are arranged in the accommodating space, which not only protects the fan blades 11 and prevents the fan blades 11 from causing harm to the user when the fan blades 11 rotate, but also ensures that the fan motor 14 can drive the fan blades 11 to rotate and supply air to the room or people, thereby achieving the effect of dispelling hot air or lowering the room temperature.

[0051] In an optional embodiment, a fixing structure is provided at the end of the base 20 facing away from the support assembly 30. The fixing structure includes a suction cup assembly for securing the circulation fan to a placement surface. The placement surface can be a smooth, flat surface such as floor tiles. The suction cup assembly can be made of a plastic material with a certain degree of rigidity and flexibility, such as silicone rubber, PVC, nitrile rubber, polyurethane, or a vinyl-containing polymer. Utilizing the above technical solution, the base 20 of the circulation fan can be secured to the placement surface via the suction cup assembly.

[0052] Specifically, the suction cup assembly includes a suction cup 21 with a hollow conical cavity and an exhaust valve 22 provided on the suction cup. After the suction cup 21 rests on the placement surface, the suction cup 21 is pressed toward the base 20 through the support assembly 30, so that the air in the hollow conical cavity of the suction cup 21 is discharged through the exhaust valve 22; releasing the support assembly 30 allows the suction cup 21 to automatically reset. During the process of self-resetting, the suction cup 21 generates negative pressure in the hollow conical cavity of the suction cup 21, so that the suction cup 21 can be adsorbed on the placement surface, ensuring that the circulation fan can be firmly placed on the placement surface.

[0053] It should be noted that the suction cup 21 can also be pressed on the placement surface by the gravity of the circulation fan itself, and other methods can also be used to extract the gas in the hollow conical cavity through the exhaust valve 22, so that the hollow conical cavity of the suction cup 21 generates negative pressure during the process of the suction cup 21 self-resetting, thereby ensuring that the circulation fan can be firmly placed on the placement surface; at the same time, the placement surface can also include a rough surface of an object, which is not limited in this application.

[0054] In an optional embodiment, a suction cup air cavity 211 and a suction cup flow channel 212 connected to the suction cup air cavity are provided on the suction cup 21, wherein the exhaust valve 22 is provided on the suction cup flow channel 212, so that the gas in the hollow conical cavity of the suction cup 21 can pass through the suction cup air cavity 211 and then be discharged to the outside of the suction cup 21 through the suction cup flow channel 212. The exhaust valve 22 is used to discharge the gas in the suction cup flow channel 212 while preventing external gas from entering the suction cup flow channel 212.

[0055] Specifically, the base 20 is provided with a base cavity 23 and an exhaust hole 231. The suction cup 21 is mounted on the base cavity 23, and the suction cup flow channel 212 is connected to the exhaust hole 231. In this embodiment, the suction cup 21 and the base cavity 23 are both rectangular in shape, and the exhaust hole 231 is provided on the side wall of the base cavity 23. After the suction cup 21 is mounted on the base cavity 23, the suction cup flow channel 212 can be fixed to the exhaust hole 231, or the suction cup flow channel 212 can pass through the exhaust hole 231 and be flush with the outer side surface of the exhaust hole 231.

[0056] In an optional embodiment, the exhaust valve 22 may include an elastic member (not shown in the figure) and a baffle (not shown in the figure), and the elastic member is used to abut the baffle against the side of the suction cup flow channel 212 facing the suction cup air cavity 211.

[0057] Specifically, an exhaust valve mounting portion (not shown in the figure) is provided on the suction cup flow channel 212, and the diameter of the exhaust valve mounting portion is larger than the diameter of the suction cup flow channel 212, wherein the exhaust valve mounting portion is tapered on the side facing the suction cup air cavity 211, the flow blocking member can be a steel ball, etc., and the elastic member can be a spring, etc.; the spring is used to abut the flow blocking member against the tapered part of the exhaust valve mounting portion, so that the flow blocking member on the exhaust valve mounting portion can be pushed open when the suction cup air cavity 211 is exhausted, thereby allowing the gas to be discharged through the suction cup flow channel 212, and after the gas in the suction cup air cavity 211 is exhausted, the flow blocking member is reset under the elastic force of the elastic member, isolating the suction cup flow channel 212 from the outside.

[0058] In an optional embodiment, the exhaust valve 22 may include a valve body (not shown in the figure) and a valve (not shown in the figure) installed on the valve body, wherein the valve is provided with a fan (not shown in the figure) that can be opened in one direction so that the gas in the suction cup air cavity 211 can be discharged through the valve.

[0059] Specifically, the number of fan members can be one or two. When the gas in the suction cup air cavity 211 is discharged through the suction cup flow channel 212, the fan member automatically opens. After the gas in the suction cup flow channel 212 is completely discharged, the fan member automatically closes. The fan member is closed by the elastic force of the elastic member, and opened by gas pressure. Other driving mechanisms can also be used, and this application is not limited thereto.

[0060] In an optional embodiment, the exhaust valve 22 may include a rubber plug arranged on the suction cup flow channel 212, which is used to isolate the suction cup air cavity 211 from the external air circulation. When the gas in the suction cup air cavity 211 is discharged through the suction cup flow channel 212, the rubber plug is opened to connect the suction cup flow channel 212 with the outside; after the gas in the suction cup flow channel 212 is discharged, the rubber plug is installed on the suction cup flow channel 212 to prevent external air from entering the suction cup air cavity 211.

[0061] In an optional embodiment, the suction cup 21 includes a suction cup body and a soft rubber ring (not shown in the figure) arranged on the suction cup body, wherein a connecting column (not shown in the figure) protruding outward is provided in the center of the side of the suction cup body facing away from the soft rubber ring, and the connecting column is connected to the base 20.

[0062] Specifically, a circle of soft rubber grooves (not shown in the figure) is provided around the suction cup body. The soft rubber ring is bonded in the soft rubber groove by glue or other means so that the soft rubber ring can fill the soft rubber groove and partially extend out of the soft rubber groove. When the suction cup body is pressed onto the surface of an object, especially a rough surface of an object, the soft rubber ring can be deformed, so that the suction cup is tightly attached to the surface of the object, avoiding air residue between the suction cup and the surface of the object and affecting the vacuum degree of the suction cup.

[0063] In an optional embodiment, the suction cup body is provided with a circle of internal deformation grooves recessed into the suction cup body along the inner edge of the soft rubber ring, so that the suction cup body forms a boss toward the connecting column, ensuring that the suction cup body has stronger deformation ability.

[0064] In an optional embodiment, a drive mechanism 40 is mounted on the support assembly 30, and the body 10 is mounted on the support assembly 30 via the drive mechanism 40. The drive mechanism 40 includes a first rotating assembly 41 and a second rotating assembly 42 rotatably mounted on the first rotating assembly 41. In this embodiment, the first rotating assembly 41 has a first turning direction, and the second rotating assembly 42 has a second turning direction. The first turning direction and the second turning direction are perpendicular to each other, so as to meet the air supply angle requirements of the circulation fan for the user.

[0065] Among them, if the first turning direction is the lateral rotation direction of the circulation fan, the second turning direction is the longitudinal rotation direction of the circulation fan; if the first turning direction is the longitudinal rotation direction of the circulation fan, the second turning direction is the lateral rotation direction of the circulation fan, and this application does not limit it.

[0066] Specifically, the first rotating assembly 41 includes a first movable frame 411 and a first fixed frame 412, with the first fixed frame 412 being rotatably connected to the first movable frame 411. The second rotating assembly 42 includes a second fixed frame 421 and a second movable frame 422, with the second fixed frame 421 being rotatably connected to the second movable frame 422. In this embodiment, the fan motor 14 is mounted on the second fixed frame 421, which is rotatably mounted on the first movable frame 411. The second movable frame 422 is rotatably mounted on the first fixed frame 412, and the first fixed frame 412 is fixed to the support assembly 30. After adopting the above technical solution, when the circulation fan is working, the upper and lower angles of the body 10 can be adjusted through the relative relationship between the second fixed frame 421 and the second movable frame 422 and the first movable frame 411 and the first fixed frame 412; the left and right angles of the body 10 can be adjusted through the relative relationship between the second fixed frame 421 and the first movable frame 411 and the second movable frame 422 and the first fixed frame 412, so that the air supply angle of the circulation fan can be adjusted at multiple angles, with a reasonable structure and strong functions.

[0067] In an optional embodiment, the first movable frame 411 and the first fixed frame 412 are both L-shaped structures, wherein the horizontal end of the first movable frame 411 is rotatably connected to the horizontal end of the first fixed frame 412 to form a U-shape, and the second fixed frame 421 can be rotatably installed on the vertical end of the first movable frame 411, and the second movable frame 422 can be rotatably installed on the vertical ends of the first fixed frame 412 respectively. Not only is the structural design reasonable, but it also makes the overall circulation fan more compact. Through the different rotation directions of the first rotating component 41 and the second rotating component 42, the air supply angle of the circulation fan can be adjusted according to the needs of the user, meeting the user's demand for the air supply angle of the circulation fan.

[0068] It should be noted that the U-shaped opening direction can be toward the top of the circulation fan, and the U-shaped opening direction can also be toward the side of the circulation fan, without application or limitation.

[0069] Specifically, the first movable frame 411 and the first fixed frame 412 can be formed by a bending process, which can not only effectively control the manufacturing cost of the first movable frame 411 and the first fixed frame 412, but also ensure the hardness of the first movable frame 411 and the first fixed frame 412, thereby improving the service life of the first rotating assembly 41.

[0070] It should be noted that the first movable frame 411 and the first fixed frame 412 can also have other curved structures, such as an arc-shaped structure, wherein one end of the first movable frame 411 is rotatably connected to one end of the first fixed frame 412, and the two ends of the body 10 are respectively connected to the other ends of the first movable frame 411 and the first fixed frame 412. It should be noted that the first movable frame 411 and the first fixed frame 412 can also have other curved structures, such as an arc-shaped structure, wherein one end of the first movable frame 411 is rotatably connected to one end of the first fixed frame 412, and the two ends of the body 10 are respectively connected to the other ends of the first movable frame 411 and the first fixed frame 412. In an optional embodiment, the second fixed frame 421 includes a first mounting surface 4212, a second mounting surface 4213, and a third mounting surface 4211. The first mounting surface 4212 is rotatably connected to the first movable frame 411, the second mounting surface 4213 is rotatably connected to the second movable frame 422, and the third mounting surface 4211 is used to mount the body 10, resulting in a simple structure and a reasonable design.

[0071] Specifically, the first mounting surface 4212 and the second mounting surface 4213 are respectively arranged on the two adjacent sides of the third mounting surface 4211, and the second movable frame 422 is an L-shaped structure. The horizontal end of the second movable frame 422 is rotatably connected to the second mounting surface 4213, and the vertical end of the second movable frame 422 is rotatably connected to the first fixed frame 412, so that the body 10 on the third mounting surface 4211 can be rotated left and right through the relationship between the second mounting surface 4213 and the second movable frame 422 and the relationship between the first movable frame 411 and the first fixed frame 412, and the body 10 can be rotated up and down through the relationship between the first mounting surface 4212 and the first movable frame 411 and the relationship between the second movable frame 422 and the first fixed frame 412, thereby ensuring that the user can adjust the air supply angle of the circulation fan as needed, thereby meeting the user's demand for the air supply angle of the circulation fan.

[0072] It should be noted that the second movable frame 422 may also be other curved structures, such as an arc-shaped structure, which is not limited in this application.

[0073] After adopting the above technical solution, since the two adjacent sides of the third mounting surface 4211 are bent to form the first mounting surface 4212 and the second mounting surface 4213, it can be ensured that the second fixed frame 421 has sufficient strength to support the weight of the body 10; at the same time, the second movable frame 422 can also be formed by a bending process, which not only reduces the manufacturing cost of the second rotating assembly 42, but also makes the structural design relatively reasonable and practical.

[0074] In an optional embodiment, the first rotating assembly 41 further includes a first bearing 416 , which is disposed between the first movable frame 411 and the first fixed frame 412 , so that the first movable frame 411 can be rotatably mounted on the first fixed frame 412 .

[0075] Specifically, the first bearing member 416 is a bearing seat. The first fixing frame 412 is provided with a bearing seat fixing portion (not shown) and a first fixing frame fixing portion (not shown). The first fixing frame fixing portion is disposed outside the bearing seat fixing portion. In this embodiment, the first bearing member 416 is mounted to the bearing seat fixing portion via screws, and the first fixing frame 412 is fixed to the support assembly 30 via the first fixing frame fixing portion, resulting in a simple structure and a reasonable design.

[0076] In an optional embodiment, a fixed frame bearing 417 is provided on the vertical end of the first movable frame 411, and a movable frame bearing 426 is provided on the vertical end of the second movable frame 421. The second fixed frame 421 is connected to the first movable frame 411 through the fixed frame bearing 417, and the second movable frame 422 is connected to the first fixed frame 412 through the movable frame bearing 426. This not only has a simple structure, but also ensures smooth rotation between the second fixed frame 421 and the first movable frame 411 and between the second movable frame 422 and the first fixed frame 412.

[0077] In an optional embodiment, the first rotating assembly 41 further includes a first driving member 413 , wherein the first driving member 413 is mounted on the first movable frame 411 and is configured to drive the second rotating assembly 42 to rotate relative to the first movable frame 411 .

[0078] It should be noted that the first driving member 413 can be installed on the vertical end of the first movable frame 411, and the first driving member 413 can also be installed on the horizontal end of the first movable frame 411. The first driving member 413 can be directly connected to the second rotating component 42, and the first driving member 413 can also be connected to the second rotating component 42 through other transmission components. This application is not limited to this. Its main purpose is to drive the second rotating component 42 to rotate relative to the first movable frame 411 so as to realize the up and down rotation of the body 10, ensuring that the user can adjust the air supply angle of the circulation fan as needed.

[0079] In an optional embodiment, the first rotating assembly 41 further includes a first transmission member 414, which includes a first driving wheel 4142 and a first driven wheel 4143, wherein the first driven wheel 4143 is in driving connection with the first driving wheel 4142. In this embodiment, the first driving member 413 includes a first motor, the first driving wheel 4142 is mounted on the output shaft of the first motor, and the first driven wheel 4143 is mounted on the second rotating assembly 42. This not only allows the first driving member 413 to control the up and down rotation of the body 10, but also allows long-distance transmission, so that the first driving member 413 can be installed at any position on the first movable frame 411, that is, a reasonable design is made according to the structure of the circulating fan to ensure the compactness of the circulating fan.

[0080] In an optional embodiment, the first transmission member 414 includes a first rack 4141 , and the first driving wheel 4142 is transmission-connected to the first driven wheel 4143 via the first rack 4141 .

[0081] Specifically, both ends of the first rack 4141 are provided with teeth, namely a first tooth portion 4141a and a second tooth portion 4141b. The first driving wheel 4142 is provided with a driving wheel tooth portion 4142a. The driving wheel tooth portion 4142a meshes with the first tooth portion 4141a, and the second tooth portion 4141b meshes with the first driven wheel 4143. When the first driving member 413 is in operation, the first driving member 413 can drive the first driving wheel 4142 to rotate and move the first rack through the meshing connection between the driving wheel tooth portion 4142a and the first tooth portion 4141a. The first rack drives the first driven wheel 4143 to rotate through the meshing connection between the second tooth portion 4141b and the first driven wheel 4143, thereby enabling the second rotating assembly 42 to rotate relative to the first rotating assembly 41.

[0082] In an optional embodiment, the orientation of the first tooth portion 4141a is perpendicular to the orientation of the second tooth portion 4141b, for example, the first tooth portion 4141a is oriented toward the right side of the circulation fan, and the second tooth portion 4141b is oriented toward the upper end of the circulation fan. In this embodiment, the first rack has a two-degree bend structure, with the first tooth portion 4141a and the second tooth portion 4141b respectively disposed at opposite ends of the first rack, so that the first driving member 413 can drive the second rotating assembly 42 to rotate over a long distance, while simultaneously converting the horizontal rotation direction of the first driving wheel 4142 into the vertical rotation direction of the first driven wheel 4143.

[0083] In an optional embodiment, the first rotating assembly 41 further includes a guide seat 415 disposed on the first movable frame 411 , a sliding member 41411 is provided on the first rack, and the first rack 4141 is slidably mounted on the guide seat 415 via a guide rail 41411 .

[0085] In an alternative embodiment, the guide seat 415 may be integrally formed with the first movable frame 411, or the guide seat 415 may be separately formed from the first movable frame 411. In this embodiment, the guide seat 415 may be separately formed from the first movable frame 411, the first movable frame 411 is provided with a fixed frame mounting groove 4111, the first driving member 413 is mounted in the fixed frame mounting groove 4111, and the guide seat 415 is then mounted on the upper end of the first driving member 413.

[0086] Specifically, the guide base 415 is provided with an open driver mounting slot (not shown), into which the first driver 413 is mounted. In this embodiment, the first rack 4141 is mounted on the outer side of the upper end surface of the driver mounting slot. The outer side of the lower end surface of the driver mounting slot is provided with a guide base rotating shaft. The guide base 415 is rotatably mounted on the first bearing 416 via the guide base rotating shaft.

[0095] In an optional embodiment, the rod structure further includes a sleeve (not shown in the figure), and the second rod moves linearly on the circulation fan through the sleeve.

[0096] Specifically, the second rod is arranged between the first rod and the third rod, and the sliding direction of the second rod is perpendicular to the sliding direction of the first rod, so that the first rod can drive the third rod to slide or swing through the second rod, thereby driving the body 10 to swing.

[0097] In an optional embodiment, the third rod is rotatably mounted on the circulation fan through a rotating fulcrum at one end close to the body 10. When the second rod slides in the slide groove on the third rod, the third rod rotates around the rotating fulcrum, thereby driving the body 10 on the third rod to swing.

[0101] Specifically, the second rotating assembly 42 further includes a support base 425 disposed on the second movable frame 422, and the support base 425 is mounted on the upper end of the second driving member 423. In this embodiment, the second driving member 423 is a driving motor, and the shape and size of the driving member fixing groove 4221 are adapted to the shape and size of the second driving member 423. After the second driving member 423 is fixed in the driving member fixing groove 4221, the support base 425 is mounted on the upper end of the second driving member 423, so that the fixing flange of the second driving member 423 is clamped between the support base 425 and the second movable frame 422, thereby improving the stability of the fixing of the second driving member 423.

[0102] The support base 425 is provided with a shaft portion 4251 , and the second fixed frame 421 is rotatably mounted on the shaft portion 4251 via the second transmission member 424 , so that the second driving member 423 can drive the second fixed frame 421 to rotate relative to the second movable frame 422 via the second transmission member 424 .

[0106] In an optional embodiment, the first driven wheel 4143 has a driven gear mounting shaft, and the first driven wheel 4143 is connected to the fixed frame bearing 417 through the driven gear mounting shaft to ensure smooth rotation between the first driven wheel 4143 and the first movable frame 411.

[0107] In an optional embodiment, the front housing 12 includes an air duct 122 and a front mesh cover 121, wherein the front mesh cover 121 is disposed at the front end of the air duct 122. In this embodiment, the distance from the center of the fan blade 11 to the front mesh cover 121 is at least 15 mm to 35 mm to ensure that the air duct 122 has an optimal air guiding effect. It is understood that if the length of the air duct is too short, it will not serve the purpose of guiding air, and if the length of the air duct is too long, it will increase the weight of the front housing 12, waste materials, and increase manufacturing costs.

[0108] After adopting the above technical solution, since the application limits the length of the air guide tube 122, it can not only ensure the wind guiding function of the air guide tube 122, but also enable the wind of the circulating fan to be gathered in the process of blowing from the center of the fan blade 11 to the front mesh cover 121, reducing the blowing area, and the wind speed is also accelerated, thereby increasing the air supply distance of the circulating fan, and then it can be blown to the user more evenly through the front mesh cover 121, which is more comfortable.

[0109] In an optional embodiment, the distance between the air guide tube 122 and the center of the fan blade 11 and the front mesh cover 121 is 35 mm. Since there is a certain error in the molding process of the air guide tube 122, the distance between the air guide tube 122 and the center of the fan blade 11 and the front mesh cover 121 can be any value between 30-40 mm to ensure that the air guide tube 122 has the best air guiding effect.

[0110] In an optional embodiment, the radial gap between the air guide tube 122 and the fan blades 11 is 2-10 mm to avoid interference between the air guide tube 122 and the fan blades 11, while ensuring that the wind generated by the fan blades 11 can flow from the radial gap between the air guide tube 122 and the fan blades 11 along the guide direction of the air guide tube 122 to the front mesh cover 121.

[0114] In an optional embodiment, the front mesh cover 121 includes a mesh cover outer ring and a mesh cover inner ring, wherein the mesh cover inner ring is arranged on the inner side of the mesh cover outer ring, and the mesh cover outer ring has a first air outlet mesh plate 1212. The first air outlet mesh plate 1212 can allow the wind blown out by the circulation fan to diffuse to all sides, and the mesh cover inner ring is used to eliminate the noise generated when the circulation fan is working.

[0115] Specifically, the inner circle of the mesh cover has a second air outlet mesh plate 1213, and the rotation angle of the second air outlet mesh plate 1213 is opposite to the rotation angle of the first air outlet mesh plate 1212, which can play a role in noise reduction.

[0116] In an optional embodiment, the inner ring of the mesh cover includes an outer ring and a center disk 1214, wherein the center disk is located inside the outer ring, and the second air outlet mesh plate 1213 is connected between the outer ring and the center disk 1214.

The diameter of the inner ring is 10 to 30 mm, thereby reducing the noise of the circulation fan by 1.3 dB.

[0117] In an optional embodiment, a solid structure is provided at the center of the inner ring of the mesh cover, and the outer diameter of the solid structure is equal to (0.02-0.3) times the outer diameter of the inner ring of the mesh cover.

[0118] In an optional embodiment, a cross-shaped structure is provided on the inner side of the inner circle of the mesh cover.

[0119] In an optional embodiment, a second air outlet mesh plate composed of grille plates is provided on the inner ring of the mesh cover, and the number of the grille plates is less than the number of grille bars on the first air outlet mesh plate.

[0120] In an optional embodiment, the width of the grid plate is smaller than the width of the grid bars.

[0121] In an optional embodiment, the rotation direction of the grid plate is opposite to the rotation direction of the grid bars.

[0122] In an optional embodiment, the first air outlet mesh plate 1212 is twisted counterclockwise on the outer ring of the mesh cover, and the inner ring of the mesh cover is a solid structure or a concentric circle structure, so as to better eliminate the noise generated when the circulation fan is working.

[0123] In an optional embodiment, the front mesh cover 121 includes a solid mesh inner ring and a mesh outer ring with a first air outlet mesh plate, wherein the mesh inner ring is located inside the mesh outer ring, mainly for reducing the noise generated when the circulation fan is in operation.

[0124] In an optional embodiment, the inner ring of the mesh cover and the outer ring of the mesh cover can be integrally formed to better control the manufacturing cost of the front mesh cover 121.

[0125] In an optional embodiment, the front mesh cover 121 is detachably connected to the air duct 122. Specifically, the outer edge 1211 has a flange protruding toward the rear housing 13. The air duct 122 includes an outer shell 1221, an inner shell 1222, and reinforcing ribs 1223. The reinforcing ribs 1223 are disposed between the outer shell 1221 and the inner shell 1222.

[0126] In this embodiment, there are multiple reinforcing ribs 1223, and the multiple reinforcing ribs 1223 are arranged in a circular array between the outer shell 1221 and the inner shell 1222. This not only ensures the strength of the air guide tube 122, but also reduces the manufacturing cost of the air guide tube 122 and saves a large amount of manufacturing materials. In addition, it is convenient to form a cavity between the outer shell 1221 and the inner shell 1222 to install other electronic components of the circulation fan, making the structure of the circulation fan more compact and the design more reasonable.

[0127] In an optional embodiment, the length of the inner shell 1222 extending toward the front mesh cover 121 is smaller than the length of the outer shell 1221 extending toward the front mesh cover 121, so that the flange is just snapped onto the reinforcing rib 1223, thereby improving the stability of the connection between the front mesh cover 121 and the air guide tube 122.

[0128] In an optional embodiment, the rear shell 13 includes a rear mesh cover 132, and a rear shell storage cavity 131 is provided on the rear mesh cover 132, wherein the driving mechanism 40 is stored in the rear shell storage cavity 131 to prevent the driving mechanism 40 from affecting the appearance of the circulation fan. At the same time, the driving mechanism 40 can also be protected. When working in circulation, the gas can enter the accommodating space from the rear mesh cover 132 and then be discharged through the front mesh cover 121 along the air guide tube 122, reducing the impact of the rear shell 13 on the air duct formed by the air guide tube 122 when the body 10 rotates, making the air suction smoother and the air volume more sufficient.

[0129] After adopting the above technical solution, since the air guide tube 122 surrounds the outside of the fan blade 11, the air guide tube 122 can be used to gather the wind and increase the wind force, so that the gas can be discharged from the rear mesh cover 132 along the air guide tube 122 and the front mesh cover 121, bringing better heat dissipation effect to the user.

[0130] In an optional embodiment, the support assembly 30 includes a support column, a storage shell 31 with an opening 311 is provided on the support column, and the driving mechanism 40 is installed in the storage shell 31 .

[0131] Specifically, the storage shell 31 is cylindrical, and the shape of the rear shell storage cavity 131 is adapted to the shape of the storage shell 31, so that the rear shell 13 can be rotatably mounted on the storage shell 31 through the rear shell storage cavity 131. In this embodiment, the opening 311 of the storage shell 31 is set at the upper part of the storage shell 31 and faces the rear shell 13. The first fixed frame 412, the first movable frame 411, the second fixed frame 421 and the second movable frame 422 are sequentially installed in the storage shell 31 from the opening 311 of the storage shell 31. Then, the fan motor 14 and the bottom of the rear shell storage cavity 131 are fixed to the second fixed frame 421, so that the entire drive mechanism 40 can be installed in the cavity formed by the rear shell storage cavity 131 and the storage shell 31. When the circulation fan is working, the drive mechanism 40 can drive the rear shell storage cavity 131 to rotate relative to the storage shell 31. The structure is simple and the design is reasonable.

[0132] In an optional embodiment, the first fixed frame 412 is installed in the storage shell 31 through the first fixed frame fixing portion, and the first movable frame 411, the second fixed frame 421 and the second movable frame 422 are rotatably connected to the first fixed frame 412 in sequence.

[0133] In an optional embodiment, the rear shell storage cavity 131 is a groove formed by the rear shell 13 being recessed into the accommodating space. The width of the rear shell storage cavity 131 is greater than the overall width of the driving mechanism 40 , so that the entire driving mechanism 40 can be accommodated in the rear shell storage cavity 131 .

[0134] In an optional embodiment, a rear shell shaft hole 1313 is provided on the rear shell 13, and the output end of the fan motor 14 passes through the rear shell shaft hole 1313 and is connected to the fan blade 11, so that the fan motor 14 can drive the fan blade 11 to rotate relative to the rear shell 13, bringing better heat dissipation effect to the user.

[0135] In an optional embodiment, the rear shell 13 is provided with a fan blade avoidance groove 1312 on the side facing away from the rear shell storage cavity 131, and the fan blade 11 is provided with a fan blade shaft 1121. The fan blade shaft 1121 is connected to the output shaft of the fan motor 14 at the position of the fan blade avoidance groove 1312, which can effectively provide sufficient installation space for the fan blade 11 and avoid the problem of collision between the fan blade 11 and the rear shell 13.

[0136] In an optional embodiment, the rear shell 13 is provided with a rear shell fixing portion 1311 at the position of the rear shell receiving cavity 131 , wherein the rear shell 13 is fixed to the driving mechanism 40 via the rear shell fixing portion 1311 .

[0137] Specifically, the second fixing frame 421 is provided with a fixing frame mounting portion and a fixing frame through-hole 4211a. The fan motor 14 passes through the fixing frame through-hole 4211a and the rear shell shaft hole 1313 in sequence and is connected to the fan blade shaft 1121. The second fixing frame 421 is fixed to the rear shell fixing portion 1311 through the fixing frame mounting portion.

[0138] In an optional embodiment, the fan blade 11 includes a fan blade fixing shaft 112 set at the center of the fan blade 11 and a blade assembly 111 located outside the fan blade fixing shaft 112, wherein the fan blade rotating shaft 1121 is set at the center of the fan blade fixing shaft 112. In this embodiment, the blade assembly 111 includes a first blade 1111, a second blade 1112 and a third blade 1113, the first blade 1111 and the second blade 1112 twist in the same direction, and the third blade 1113 is connected between the middle parts of the first blade 1111 and the second blade 1112. This can not only change the pressure distribution on the first blade 1111 and / or the second blade 1112 when the blade assembly 111 rotates, but also make the area with larger pressure difference more widely distributed, thereby avoiding the gas on the first blade 1111 and / or the second blade 1112 from easily generating vortexes or separation phenomena, thereby effectively improving the kinetic energy of the gas, and having the advantages of concentrating the airflow, increasing the flow rate and reducing noise.

[0139] In an optional embodiment, the number of blade assemblies 111 is at least three groups, and the three groups of blade assemblies 111 are evenly spaced on the outside of the fan blade fixing shaft 112 with the fan blade fixing shaft 112 as the center, which can effectively increase the output air volume of the circulating fan and the distance of the airflow entering the indoor or environmental space, while also ensuring the stability of the rotation of the fan blades 11 and reducing noise.

[0140] In an optional embodiment, the first blade 1111 includes a first section 11111 and a second section 11112, wherein the first section 11111 is connected to the fan blade fixing shaft 112, the second section 11112 is connected to the first section 11111, and the third blade 1113 is arranged between the first section 11111 and the second section 11112, so that the blade assembly 111 has the function of guiding the airflow and reducing the resistance of the airflow output, thereby increasing the airflow flow rate, and then extending the airflow output distance, thereby improving the regulation effect of the indoor airflow circulation temperature.

[0141] In an optional embodiment, the width of the first section 11111 is different from the width of the second section 11112 and the width of the second blade 1112. When the fan motor 14 drives the blade assembly 111 to rotate, the width of the first section 11111 and the second section 11112 and the second blade 1112 can generate air volumes of different sizes and blowing at different angles. These air volumes of different sizes and different angles all act on the air guide 122 and are discharged from the front mesh cover 121 along the air guide 122 and blown to the surrounding areas of the room, thereby reducing the indoor temperature.

[0142] In an optional embodiment, the first section 11111 is inclined to the fan blade fixing axis 112 and forms a first angle, and the second blade 11112 is inclined to the fan blade fixing axis 112 and forms a second angle. The first angle is different from the second angle, which can effectively change the flow direction of the airflow, so that the airflow is discharged from the front mesh cover 121 in turn and blows to all sides of the room.

[0143] In an optional embodiment, the second section 11112 and the third blade 1113 are arranged at an angle to form a third angle. The third angle is different from the first angle and the second angle, which once again effectively changes the flow direction of the airflow so that the airflow is discharged from the front mesh cover 121 in turn and blows to all sides of the room.

[0144] In an optional embodiment, the third blade 1113 is concentrically arranged with the fan blade fixing shaft 112, which not only reduces the resistance encountered by the blade assembly 111 during operation, but also enhances the strength of the first blade 1111 and the second blade 1112, thereby increasing the service life of the first blade 1111 and the second blade 1112.

[0145] In an optional embodiment, the third blade 1113 has a triangular structure, wherein the first blade 1111 is connected to one side of the third blade 1113, and the second blade 1112 is connected to the other side of the third blade 1113. The design can be based on the stress conditions of the first blade 1111 and the second blade 1112. The blade assembly 111 can generate a large amount of air while ensuring the service life of the blade assembly 111. The structure is simple and the design is reasonable.

[0146] In an optional embodiment, the circulation fan is provided with a sensor and an MCU control chip arranged on the circuit board 50 , wherein the sensor is electrically connected to the MCU control chip for controlling the direction of the driving mechanism 40 and the power supply of the fan motor 14 .

[0148] It should be noted that the sensor can be an infrared sensor or a camera, etc. Its main purpose is to enable the fan motor 14, the first drive member 413 and the second drive member 423 to be adjusted after the sensor signal is fed back to the MCU control chip, so as to control the rotation speed of the fan motor 14 and the direction of the drive mechanism 40, etc.

[0149] After adopting the above technical solution, since this application uses an infrared sensor to sense whether a person is present, and then transmits the signal obtained by the infrared sensor to the MCU control chip to control the switch and speed of the circulation fan, it is not only more humane but also saves energy.

[0150] In an optional embodiment, the sensor may also be a temperature sensor, and the signal of the temperature sensor may be DS18B20, so that the circulation fan can control the fan speed according to the current room temperature to save energy.

[0151] In an optional embodiment, the sensor can also be a sound sensor, so that the circulation fan can judge the surrounding movement based on the sound, and then control the switch of the circulation fan to save energy.

[0152] In an optional embodiment, the sensor mounting cavity 33 is arranged below the storage shell 31, wherein a window is provided on one side of the sensor mounting cavity 33, and the other side of the sensor mounting cavity is an open end, so that the sensor can be installed in the sensor mounting cavity through the open end, and then the sensor transmits a signal to the outside of the sensor mounting cavity through the window to obtain a detection signal.

[0153] In an optional embodiment, the support assembly 30 further includes a first cover plate 32, which covers the open end, not only encapsulating the sensor in the sensor installation cavity to protect the sensor, but also does not affect the aesthetics of the circulation fan.

[0154] In an optional embodiment, the first cover plate 32 is in a concave shape, and its two protruding ends are fixed in the sensor installation cavity by screws.

[0155] In addition, the sensor can also be installed above the rear shell storage cavity 131. Specifically, a sensor mounting portion 1314 is provided at the upper end of the rear shell storage cavity 131, wherein the sensor is detachably mounted on the sensor mounting portion 1314. This not only ensures the sensor's detection range, but also allows the heat generated by the sensor during operation to be dissipated to the outside through the airflow generated by the body 10. Therefore, the peripheral side of the sensor mounting portion is designed with a hole structure, which is simple and reasonable.

[0156] In an optional embodiment, a display screen 60 is also provided on the circulation fan, which is electrically connected to the MCU control chip and is used to display the current room temperature, the speed of the fan motor 14 and the working mode of the circulation fan, etc., so that people can see it at a glance.

This application is not limited thereto.

[0158] In an optional embodiment, the display screen is arranged at 30-70 mm from the lower end of the front shell.

[0159] In an optional embodiment, the display screen 60 can be set on the end surface of the first cover plate 32 and designed as an integral part with the first cover plate 32, and then the first cover plate 32 is covered on the open end of the sensor installation cavity 33. The design is simple but reasonable.

[0160] Specifically, a display screen fixing portion is provided at the bottom of the sensor installation cavity 33 , and the first cover plate 32 is fixed to the display screen fixing portion by fasteners.

[0165] In an optional embodiment, the circulation fan is also provided with a wireless communication module, which may be USR-215b, so that the mobile phone can send a signal to the MCU control chip through the wireless communication module to adjust the working mode of the circulation fan, or receive a signal through the wireless communication receiving module to display the working status of the circulation fan on the operating interface of the mobile phone or other electronic device.

[0166] After adopting the above technical solution, since the circulation fan of the present application is provided with a sensor and a display screen 60, the sensor can be used to determine whether there is a person within a certain range of the circulation fan, and the signal collected by the sensor is transmitted to the MCU control chip, thereby controlling the operating status of the circulation fan. Among them, the display screen 60 allows the user to more intuitively understand the operating status of the circulation fan.

[0167] In addition, the circulation fan of the present application can easily realize the left and right swing and up and down swing of the circulation fan through the first rotating component 41 that rotates left and right and the second rotating component 42 that rotates up and down.
