[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation.

Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0033] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0034] The present application provides a fan to solve the problem in the related art that the pitch assembly of the fan is directly exposed to the outside, which may cause collisions and affect the overall appearance of the fan.

[0035] See also Figures 1 to 3 A fan includes a frame 100, a pitch assembly 200, and a shield assembly 300. An air supply assembly 110 is provided on the frame 100. The pitch assembly 200 is disposed between the frame 100 and the air supply assembly 110. The pitch assembly 200 includes a fixed element 210 and a movable element 220. The fixed element 210 is disposed on the frame 100, and the movable element 220 is disposed on the air supply assembly 110. The fixed element 210 and the movable element 220 can be relatively fixed. The shield assembly 300 is disposed on the air supply assembly 110, and the shield assembly 300 can shield the pitch assembly 200.

[0036] Specifically, when using the fan of this embodiment, power is supplied to the air supply assembly 110, and the air supply assembly 110 can then supply air normally for the user's use. When the pitch angle between the air supply assembly 110 and the frame 100 needs to be changed, the relative fixation between the fixed element 210 and the movable element 220 is released, that is, the relative fixation between the air supply assembly 110 and the frame 100 is released. At this time, the air supply assembly 110 can be rotated at will. After rotating to the appropriate angle, the fixed element 210 and the movable element 220 are re-fixed relative to each other, that is, the air supply assembly 110 and the frame 100 are relatively fixed, and the pitch angle adjustment between the air supply assembly 110 and the frame 100 is completed.

[0037] The shield assembly 300 completely obscures the pitch assembly 200, rendering it invisible. This prevents the exposed pitch structure or wiring from being directly visible, enhancing the overall aesthetics of the fan. The shield assembly 300, positioned externally to the pitch assembly 200, also protects it. Even if the pitch assembly 200 collides with an external object during transport, the shield assembly 300 prevents damage, extending the lifespan of the fan and improving its reliability and stability.

[0038] In some embodiments, for example, Figures 2 to 4 As shown, the fixed element 210 includes a rotating shaft bracket, which includes a connecting rod 212 and a support bracket 211. The support bracket 211 is disposed at one end of the connecting rod 212. The connecting rod 212 is disposed on the frame 100, and the movable element 220 is disposed on the support bracket 211. The support bracket 211 is fixed to the frame 100 via the connecting rod 212, and the movable element 220 is disposed on the support bracket 211, making the structure of this embodiment more reasonable and reliable.

[0039] In some embodiments, for example, Figure 3 、 Figure 4 As shown, the movable element 220 includes an air supply bracket, which is arranged on the air supply assembly 110. The air supply bracket can be rotatably mounted on the support bracket 211, and the air supply bracket rotates in the vertical direction. By cooperating with the support bracket 211, the air supply assembly 110 can achieve a wider range of blowing direction adjustment, and the adjustment is convenient. Specifically, in this embodiment, the support bracket 211 is rotatably arranged on the connecting rod 212, and the air supply bracket can rotate in the vertical direction relative to the support bracket 211. In this way, the air supply range of the air supply assembly 110 is ensured to be wide, making this embodiment more practical and improving the practicality and structural rationality of this embodiment.

[0040] In some embodiments, for example, Figures 3 to 5 As shown, the fixed element 210 further includes a sliding plate 213, which is mounted on the support bracket 211. The sliding plate 213 has a plurality of limiting slots 214 evenly distributed along its circumference. When the pitch angle of the air supply assembly 110 is adjusted via the pitch assembly 200, the position of the movable element 220 is limited by the sliding plate 213. The plurality of limiting slots 214 evenly distributed on the sliding plate 213 allow the movable element 220 to have multiple positions when rotating. In other words, multiple different pitch angles are set between the movable element 220 and the fixed element 210, so that the air supply assembly 110 can be rotated to different angles in the vertical direction.

[0041] In one embodiment, for example, a horizontal rotation component is also provided on the frame to drive the air supply component to rotate in the horizontal direction, and cooperate with the pitch component to make the air supply range and air supply angle of the air supply component in this embodiment more flexible, thereby improving the practicality of this embodiment.

[0042] In some embodiments, for example, Figure 3 、 Figure 4 As shown, a straight groove is provided on the air supply bracket, and a positioning bead 221 can be slidably provided in the straight groove. The positioning bead 221 can extend into the straight groove and be snapped into the limiting groove 214. When the air supply assembly 110 is rotated, the movable element 220 and the fixed element 210 rotate relative to each other, that is, the air supply bracket and the support bracket 211 rotate relative to each other. When the pitch angle needs to be changed, the positioning bead 221 on the air supply bracket is retracted into the straight groove, and the air supply bracket and the sliding plate 213 are released from relative fixation, that is, the air supply bracket and the support bracket 211 are released from relative fixation, and the air supply assembly 110 can rotate freely. After rotating to the appropriate angle, the positioning bead 221 is controlled to extend from the straight groove and snapped into the corresponding limiting groove 214, so that the air supply bracket and the sliding plate 213 are relatively fixed, that is, the movable element 220 and the fixed element 210 are relatively fixed, and the air supply assembly 110 can be maintained in the current position.

[0043] It is understood that this embodiment does not restrict the structure of the positioning bead 221, as long as the positioning bead 221 can move synchronously with the air supply bracket and be engaged within the limiting groove 214. For example, in this embodiment, the positioning bead 221 includes a straight rod and an end cap, wherein the straight rod extends into the straight groove. The straight rod and the straight groove cooperate to enable the positioning bead 221 to move with the movement of the air supply bracket. The end cap can extend into the limiting groove 214 or retract into the straight groove to achieve relative fixation or separation between the air supply bracket and the sliding plate 213.

[0044] In some embodiments, for example, Figures 3 to 5 As shown, the positioning bead 221 is provided with a guide surface. When the positioning bead 221 abuts the limiting groove 214, the guide surface abuts the edge of the limiting groove 214. An elastic element 222 is provided between the straight groove and the positioning bead 221. The elastic element 222 can push the positioning bead 221 toward the sliding plate 213. Specifically, in this embodiment, when changing the pitch angle of the air supply assembly 110, the air supply bracket can be directly rotated. Because one end of the positioning bead 221 is provided in the straight groove, and the other end extends out of the straight groove and abuts the limiting groove 214. Since the guide surface of the positioning bead 221 abuts the edge of the limiting groove 214, when the air supply bracket rotates, it will drive the positioning bead 221 to rotate together. At this time, under the action of the guide surface, the positioning bead 221 squeezes the elastic element 222 and slides out of the limiting groove 214, rotating with the air supply bracket. After rotating to close the next limit slot 214, the elastic element 222 is released, pushing the positioning bead 221 in the direction away from the straight slot, so that the end of the positioning bead 221 is re-adhesive to the limit slot 214, that is, one end of the straight slot remains in the straight slot, and the other end extends out of the straight slot again and abuts against the next limit slot 214. The air supply bracket and the sliding plate 213 are relatively fixed, that is, the movable element 220 and the fixed element 210 are relatively fixed, and the pitch angle adjustment of the air supply assembly 110 is completed.

[0045] After the adjustment is completed, if the pitch angle is still not appropriate, continue to rotate the air supply assembly 110 and repeat the above process until it is rotated to the appropriate angle.

[0046] It is understood that in this embodiment, the specific structure of the elastic element 222 is not limited, as long as it can push the positioning bead 221 toward the sliding plate 213. For example, in this embodiment, the elastic element 222 is configured as a spring. When the positioning bead 221 escapes from the limiting groove 214, it compresses the spring, accumulating force in the spring. When the position of the positioning bead 221 corresponds to the position of the limiting groove 214, the spring is released, pushing the positioning bead 221 toward the limiting groove 214.

[0047] In some embodiments, for example, Figure 3 、 Figure 4 As shown, a stopper is provided on the side of the sliding plate 213 facing the support bracket 211, and the stopper is engaged with the support bracket 211. Multiple stoppers are symmetrically arranged along the connection between the sliding plate 213 and the support bracket 211. The multiple stoppers provided on the sliding plate 213 and engaged with the support bracket 211 ensure that the sliding plate 213 does not rotate relative to the support bracket 211 during pitch angle adjustment in this embodiment, making the adjustment process more stable.

[0048] In this embodiment, a plurality of grooves are formed on the support bracket 211 , and a plurality of stoppers provided on the sliding plate 213 extend into the grooves in sequence, thereby ensuring that the sliding plate 213 and the support bracket 211 do not rotate relative to each other.

[0049] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the shield assembly 300 includes a shell, which is arranged at the center of the air supply assembly 110, and the shield assembly 300 is sleeved on the outside of the pitch assembly 200 to shield the pitch assembly 200. The pitch assembly 200 is shielded and protected by the shell. During the production and processing process, the shell can be set to any suitable shape according to actual needs, or sprayed with paint or graffiti of any shape to ensure the overall appearance of the fan is beautiful. In addition, the shell can also be set to any material as needed to protect the pitch assembly 200, so that when the pitch assembly 200 accidentally collides with the outside world, the shell will bear the force to prevent the pitch assembly 200 from being damaged.

[0050] In some embodiments, for example, Figure 1 、 Figure 2 As shown, a through hole is formed on the housing in the direction toward the frame 100, and a fixing element 210 is disposed in the through hole. The fixing element 210 is fixedly connected to the frame 100. When the pitch angle between the air supply assembly 110 and the frame 100 changes, the housing will also move with the displacement of the air supply assembly 110. Space is reserved on the housing to ensure that when the housing and the frame 100 undergo relative displacement, the housing will not interfere with the fixing element 210, thereby ensuring that the pitch angle of this embodiment can be adjusted normally and that this embodiment can be used normally.

[0051] It is understood that the shape and size of the through hole can be arbitrarily set to any appropriate size according to actual needs, as long as the housing does not affect the normal adjustment of the pitch angle. In addition, the through hole is located below the housing, that is, no matter what shape and size the through hole is opened, it will not affect the overall aesthetics of this embodiment.

[0052] In some embodiments, for example, Figure 1 、 Figure 2As shown, a vent is provided on the end of the shell away from the air supply assembly 110, and a grille 310 is provided in the vent. The air supply assembly 110 includes fan blades. When the air supply assembly 110 is blowing, the air on one side of the fan blade is usually sent to the other side by the rotation of the fan blades to form an airflow. Providing a vent on the shell can ensure that the shell does not affect the normal operation of the fan blades, and ensure the overall performance of the air supply assembly 110 of this embodiment. Furthermore, the vent is provided on the end of the shell away from the air supply assembly 110. When the air is blowing normally in this embodiment, the external gas will flow into the shell from the vent and flow out from the position of the shell close to the air supply assembly 110. The gas passing through can ventilate and dissipate heat to each component in the shell, so that the present embodiment can work for a long time.

[0053] A grille 310 is provided at the vent to filter the airflow entering the housing from the vent, and to block insects, floating debris, etc. in the air, to prevent them from entering the housing and affecting the normal operation of various components inside the housing.

[0054] In some embodiments, for example, a connecting rod extends from a through hole and is fixedly connected to the frame. The area of ​​the through hole is larger than the cross-sectional area of ​​the connecting rod. This ensures that when the housing swings with the pitch assembly, the connecting rod does not affect the swing of the through hole, thereby affecting the normal operation of this embodiment, thereby improving the structural rationality of this embodiment.

[0055] In some embodiments, the air supply assembly 110 includes a cover and fan blades. The frame 100 is further provided with a power assembly that drives the fan blades to rotate and supply air to the user. The cover covers the fan blades to protect them from external influences and also protects the user from contact with the fan blades and injury.

[0056] The shell is arranged on the outside of the air supply bracket and can cover the pitch assembly 200. The shell is also arranged on the cover body, and the shell is fixedly connected to the cover body. In this way, the shell, the cover body, and the pitch assembly 200 are all fixedly connected, which improves the structural integrity of this embodiment, makes the structural strength of this embodiment higher, and extends the service life of this embodiment.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
