[0036] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. For example, although the following embodiments are introduced in combination with a desktop fan, the fan provided by the present application is also applicable to other products which need to solve the problem of poor flexibility in up-down adjustment of the outlet angle.

[0037] It should be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "arranged", "connected" should be understood in a broad sense, for example, can be fixedly connected, or detachably connected, or integrally connected. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0038] ​The existing desktop electric fan outflow opening angle up and down adjustment flexibility problem pointed out based on the background technology. The utility model provides a fan, it is through setting up arc guide rail on the fan head and setting up connecting component on the base, to effectively solve the problem of desktop electric fan outflow opening angle up and down adjustment flexibility.

[0039] As Figures 1 to 3 The utility model provides a fan, fan includes base 1 and fan head 3. Wherein, base 1 is provided with connecting component 2, fan head 3 includes casing 31 and fan blade 32 installed in casing 31, casing 31 is provided with arc guide rail, and connecting component 2 is connected with arc guide rail, to install fan head 3 on base 1, and, arc guide rail extends vertically, and connecting component 2 can move along the length direction of arc guide rail, to adjust the included angle between fan head 3 and horizontal plane.

[0040] The base 1 in the utility model is the support part of the fan, the connecting component 2 is installed on the base 1, and the connecting component 2 is the key component for connecting the fan head 3 with the base 1;The fan head 3 includes a casing 31 and a fan blade 32 installed inside the casing 31. The casing 31 not only protects the fan blade 32, but also bears the function of adjusting the angle of the fan.

[0041] The casing 31 in the utility model is provided with an arc guide rail, which allows the fan head 3 to be adjusted relative to the base 1, and the connecting component 2 is connected with the arc guide rail. This connection method is not only stable, but also allows the connecting component 2 to move freely along the length direction of the arc guide rail. This mobility directly translates into the adjustment of the included angle of the fan head 3 relative to the horizontal plane, thereby achieving the change of the inclination angle of the fan head 3.

[0042] By moving the position of the connecting component 2 on the arc guide rail, the user can easily adjust the included angle between the fan head 3 and the horizontal plane. This design meets the different needs of different users for wind direction, improves the practicability and comfort of the fan. In addition, although the fan head 3 can adjust the angle, due to the close cooperation between the connecting component 2 and the arc guide rail, the entire fan remains stable during the adjustment process and does not affect the safety of use due to the change of angle.

[0043] Preferably, as Figure 2 The back of the casing 31 is provided with an arc-shaped handle 33 in the vertical direction, and the arc guide rail is arranged on the arc-shaped handle 33.

[0044] An arc-shaped handle 33 is arranged on the back of the shell 31 in the vertical direction. The arc-shaped handle 33 provides a comfortable gripping point for the user to carry and move the fan. In addition, an arc-shaped guide rail is arranged on the arc-shaped handle 33, so that when the user adjusts the angle of the fan head 3, the user can hold the handle and move along the guide rail, which can more easily and accurately control the movement trajectory of the fan, thereby adjusting the angle and position of the fan head 3.

[0045] Preferably, as shown in the drawings, the arc-shaped guide rail is a strip-shaped opening 311 formed on the shell 31, and the connecting member 2 comprises a connecting part 21 and an abutting part 22, the first end of the connecting part 21 is connected with the base 1, the second end of the connecting part 21 passes through the strip-shaped opening 311 and is connected with the abutting part 22, and the abutting part 22 is located inside the shell 31 and abuts against the inner wall of the shell 31. Figures 2 to 5

[0046] The arc-shaped guide rail of the utility model is designed as a strip-shaped opening 311 formed on the shell 31, which not only simplifies the manufacturing process, but also enables the connecting member 2 to move smoothly along the opening (i.e. the arc-shaped guide rail). Exemplarily, the length of the strip-shaped opening 311 determines the angle range of the fan head 3 that can be adjusted, thereby meeting the diversified needs of different users for wind direction and wind speed.

[0047] The connecting member 2 is composed of the connecting part 21 and the abutting part 22, and the two parts together realize the stable connection and angle adjustment function between the fan head 3 and the base 1. Specifically, the connecting part 21 is the main part of the connecting member 2, and the first end thereof is connected with the base 1. This connection mode ensures that the fan head 3 can still maintain stable connection with the base 1 when adjusting the angle. The second end of the connecting part 21 passes through the strip-shaped opening 311 on the shell 31 and is connected with the abutting part 22. The abutting part 22 is located inside the shell 31 and abuts against the inner wall of the shell 31. This design not only enhances the connection strength between the connecting member 2 and the shell 31, but also prevents the fan head 3 from shaking or falling off when adjusting the angle. At the same time, the shape and size of the abutting part 22 can be customized according to the shape of the inner wall of the shell 31 to ensure the best fit and stability.

[0048] When the user needs to adjust the angle of the fan head 3, the fan head 3 can be lifted or pressed, so that the connecting member 2 slides on the arc-shaped guide rail (i.e. the strip-shaped opening 311), which changes the included angle between the fan head 3 and the horizontal plane, thereby meeting the different needs of the user for wind direction and wind speed.

[0049] Preferably, the connecting part 21 is inserted and fixed with the base 1.

[0050] ​Exemplarily, the base 1 is provided with a receiving structure matched with the connecting part 21, when the connecting part 21 is inserted into the base 1, the connecting part 21 and the receiving structure are matched with each other to ensure that they are tightly connected and not easy to loosen. The plug-in fixed mode makes the assembly process of the fan more convenient. The operator only needs to insert the connecting part 21 into the receiving structure of the base 1, and the connection can be completed. This greatly reduces the assembly difficulty and improves the production efficiency.

[0051] In addition, the connecting part 21 and the base 1 can also be fixed by bolts, buckles and the like, and the fixing mode of the connecting part 21 and the base 1 is not limited in the utility model.

[0052] Preferably, the connecting part 21 is a columnar structure, and the abutting part 22 is a block structure.

[0053] The connecting part 21 is designed as a columnar structure, which provides good structural strength and stability. The columnar structure can effectively resist bending and torsional forces, ensuring that the connecting member 2 remains stable during movement. In addition, the columnar structure of the connecting part 21 also allows it to easily pass through the strip-shaped opening 311 on the cover shell 31. Since the diameter of the columnar structure is relatively small, it can move smoothly within the opening without being hindered too much.

[0054] The abutting part 22 is designed as a block structure, which can provide a larger contact area, thereby increasing the friction and stability between the inner wall of the cover shell 31. The block structure of the abutting part 22 can better resist shaking and falling during movement, ensuring that the fan head 3 remains at the desired angle.

[0055] It should be noted that the abutting part 22 of the block structure can be made of different materials as needed to increase its softness, wear resistance or shock absorbing performance. For example, rubber, silicone or other elastic materials can be used to manufacture the abutting part 22 to reduce friction and noise between the inner wall of the cover shell 31. The specific material of the abutting part 22 is not limited in the utility model.

[0056] Preferably, as shown in Figures 2 to 5 The base 1 is also provided with a limiting member 11, the limiting member 11 is arranged in the strip-shaped opening 311, the limiting member 11 is located between the connecting part 21 and the top end of the strip-shaped opening 311, the cover shell 31 is provided with a limiting structure 312, and the limiting member 11 can abut against the limiting structure 312 to limit the limit angle of the fan head 3.

[0057] The utility model discloses a limiting member 11 is additionally arranged on the base 1, and the limiting member 11 passes the strip-shaped opening 311 on the cover 31 and is located between the connecting portion 21 and the top of strip-shaped opening 311.The main role of limiting member 11 is to prevent the fan head 3 from exceeding the predetermined limit angle of elevation when adjusting the angle upward, thereby avoiding the structural damage or security risks possibly caused by the angle being too large.

[0058] In order to cooperate with limiting member 11, the cover 31 of the utility model is provided with a limiting structure 312.In the process of adjusting the angle of fan head 3, the connecting member 2 will move along the strip-shaped opening 311.When the fan head 3 approaches the predetermined limit angle of elevation, the limiting member 11 will abut against the limiting structure 312 on the cover 31.This abutment not only limits the further upward of fan head 3, but also provides intuitive feedback to the user through physical contact, indicating that the fan head 3 has reached the maximum angle of adjustment.And it also prevents structural damage caused by misoperation through physical limitation.

[0059] Preferably, the limiting structure 312 is the inner wall of the top of strip-shaped opening 311.

[0060] The utility model designs the limiting structure 312 as the inner wall of the top of strip-shaped opening 311, so that when the fan head 3 adjusts the angle upward, the limiting member 11 on the connecting member 2 will directly contact the inner wall of the top of strip-shaped opening 311.This design utilizes the structural features of the cover 31 itself, without the need for additional components, thereby reducing manufacturing costs and simplifying the assembly process.

[0061] In the process of adjusting the angle of fan head 3, the connecting member 2 will move along the strip-shaped opening 311.When the fan head 3 approaches the predetermined limit angle of elevation, the limiting member 11 will gradually approach the inner wall of the top of strip-shaped opening 311.Once the limit angle of elevation is reached, the limiting member 11 will be in close contact with the inner wall, thereby preventing the further upward of fan head 3.This physical contact not only provides intuitive feedback that the fan head 3 has reached the maximum angle of adjustment, but also ensures the stability of the fan during the adjustment process through friction or structural limitation.

[0062] Exemplarily, the limiting member 11 in the utility model can be a bolt, which passes through the base 1 and extends into the strip-shaped opening 311, the head of the bolt serves as the limiting part, and the rod of the bolt cooperates with the threaded hole on the base 1.In addition, the limiting member 11 can also be a protrusion, which will gradually approach the inner wall of the top of strip-shaped opening 311 when the fan head 3 adjusts the angle upward, and once the predetermined limit angle of elevation is reached, the slider will be in contact with the inner wall of the top of strip-shaped opening 311, thereby preventing the further upward of fan head 3.

[0063] Of course, in other embodiments, the limiting member 11 can also be a buckle, a limiting pin or the like structure, and the specific type of the limiting member 11 is not limited in the utility model.

[0064] Preferably, as shown in the drawings, the base 1 is provided with a hanging hole 15, and the fan can be fixed through the hanging hole 15. Figure 2

[0065] The hanging hole 15 can allow the user to hang the fan on the wall, ceiling or other plane through a hanging rope, hook or other fixing device. This design not only saves the ground space, but also provides a more flexible and personalized installation method for the user. For example, the user can hang the fan in the corner of the room, above the bedside or working area, to adjust the air supply direction and angle as needed, thereby improving the practicability and user experience of the fan.

[0066] Preferably, as shown in the drawings, Figure 5 and Figure 6 The base 1 includes a bottom shell 12, a rotating disc 13 and a driving assembly 14 installed in the bottom shell 12. The rotating disc 13 is installed on the top of the bottom shell 12 and can rotate relative to the bottom shell 12. The connecting member 2 is arranged on the rotating disc 13. The output end of the driving assembly 14 is connected with the rotating disc 13. The driving assembly 14 can drive the rotating disc 13 to rotate to drive the fan head 3 to rotate.

[0067] The rotating disc 13 is installed on the top of the bottom shell 12 and can rotate relative to the bottom shell 12. This design allows the fan head 3 to rotate in the horizontal plane, thereby expanding the air supply range and improving the practicability of the fan. The connecting member 2 is arranged on the rotating disc 13, which makes the fan head 3 not only be able to adjust the up-down angle relative to the base 1, but also be able to rotate with the rotating disc 13 to realize left-right swing, further increasing the flexibility and diversity of air supply. The driving assembly 14 is installed in the bottom shell 12, and the output end thereof is connected with the rotating disc 13. By controlling the start and stop of the driving assembly 14, the user can easily realize the rotation function of the fan head 3.

[0068] Preferably, as shown in the drawings, Figure 6 The driving assembly 14 includes a driving motor 141 and a gear 142 arranged on the rotating output end of the driving motor 141. An arc-shaped gear rack 131 is arranged on the rotating disc 13 and is in gear connection with the gear 142. The driving motor 141 can drive the gear 142 to rotate to drive the rotating disc 13 to rotate.

[0069] ​The driving assembly 14 mainly comprises a driving motor 141 and a gear 142 arranged at the rotating output end of the driving motor 141. Thus, the rotation of the motor is utilized to realize the rotation of the rotating disc 13 through the transmission of the gear 142. The rotating disc 13 is provided with an arc-shaped gear rack 131 which is in gear connection with the gear 142. This design allows the gear 142 to maintain stable contact with the arc-shaped gear rack 131 during rotation, thereby ensuring the smooth rotation of the rotating disc 13. The design of the arc-shaped gear rack 131 allows the rotating disc 13 to rotate continuously and smoothly within a certain range without jamming or jumping. Thus, the practicability and stability of the fan are improved, and a more smooth and comfortable user experience is provided.

[0070] When the user needs to drive the fan head 3 to rotate, the driving motor 141 is started. After receiving the starting signal, the driving motor 141 starts to rotate its output shaft, thereby driving the gear 142 to rotate. When the gear 142 rotates, its teeth are in mesh with the teeth of the arc-shaped gear rack 131, thereby driving the rotating disc 13 to rotate. The design of the arc-shaped gear rack 131 allows the rotating disc 13 to rotate continuously and smoothly within a certain range. Since the connecting member 2 is arranged on the rotating disc 13, when the rotating disc 13 rotates, the connecting member 2 and the fan head 3 will also rotate. In this way, the user can adjust the rotation angle and air supply direction of the fan head 3 as needed to obtain a more comfortable user experience.

[0071] Preferably, the edge of the rotating disc 13 is provided with a guide groove (not shown in the figure), and the bottom shell 12 is provided with a guide block (not shown in the figure) which is in cooperation with the guide groove. The guide block is slidingly arranged in the guide groove to limit the shaking of the rotating disc 13.

[0072] When the rotating disc 13 rotates under the action of the driving assembly 14, the guide block will slide in the guide groove. This sliding cooperation not only ensures the stability of the rotating disc 13 during rotation, but also effectively limits the shaking or deviation of the rotating disc 13. In addition, the cooperation of the guide groove and the guide block increases the connection stability between the rotating disc 13 and the bottom shell 12. Even when rotating at high speed or being subjected to external force, the rotating disc 13 can maintain a stable rotation track without obvious shaking or jumping. Thus, the practicability and durability of the fan are improved, and a more stable and smooth user experience is provided.
