Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to a fan with a rotating shaft. Background Technology

[0002] Existing bladeless fans mainly use vertical shaft fans, with the fan located at the bottom of the unit. An interactive screen can be set on the front of the fan casing for user operation. They mainly emit airflow by bending the nozzle, but due to inherent structural defects, the bending of the airflow by the nozzle results in a relatively large loss of wind power.

[0003] One improved solution involves using a horizontal fan to generate airflow. This airflow is then split and emitted through nozzles at the front of the fan. In this structure, the direction of the airflow generated by the horizontal fan is essentially the same as the emission direction, resulting in minimal wind power loss. However, because the horizontal fan is positioned relatively far back, the buttons or interactive screen on the fan's casing are too far away, making operation inconvenient (when used as a table fan, users sometimes have to stand up and stretch their arms over the nozzles to press the buttons on the fan casing), significantly degrading the user experience.

[0004] However, if the button is located on the rotatable nozzle at the front of the fan, although the distance is greatly shortened and the user can reach the button, the button will also rotate along with the fan because the nozzle needs to rotate to emit airflow in different directions. This will also cause the user to have to look for the button when operating the fan, reducing the interaction efficiency and user experience.

[0005] Therefore, this invention provides a fan with a rotating shaft. Utility Model Content

Figure 7 This is a top cross-sectional view of the fan with a rotating shaft according to this utility model. Figures 1 to 7 As shown, the fan with a rotating shaft of this utility model includes: a lifting base, a fan unit 2, an interactive screen 32, and a nozzle unit. The lifting base includes a base and a lifting rod 1. The fan unit 2 is connected to the upper end of the lifting rod 1. The fan unit 2 includes an air inlet 22, an air outlet 23, and a fan 21 that generates airflow. An air outlet shroud 24 is provided on the air outlet side of the fan 21.

The nozzle section is rotatably fitted onto a rotating shaft 25 between the fan section 2 and the interactive screen 32. The nozzle section includes a three-way air distribution seat 3, a first diffuser 4, and a second diffuser 5, each with an air outlet. The three-way air distribution seat 3 has a through hole 33 coaxial with the main airflow receiving pipe. The second end of the rotating shaft 25 passes through the main airflow of the three-way air distribution seat 3 and the through hole 33 to connect to the interactive screen 32. In this invention, the interactive screen 32 is connected to the fan via the rotating shaft 25 and does not rotate with the nozzle section. Furthermore, the interactive screen 32 controls the fan via a data cable, ensuring that the rotation of the interactive screen 32 is not affected regardless of the angle to which the nozzle section rotates. This shortens the operating distance for the user when using the fan and is unaffected by the rotation of the nozzle, thereby improving the interaction efficiency and user experience between the user and the fan.

The through hole 33 is rotatably sleeved on the rotating shaft 25. The first end of the rotating shaft 25 is integrally formed with the air outlet cover 24, but this is not a limitation.

[0060] In a preferred embodiment, the air distribution wall 31 includes an air distribution tip and guide slopes located on both sides. Air flowing through the guide slopes of the air distribution tip is guided to the first diffuser 4 and the second diffuser 5 to be emitted outward, but is not limited thereto.

[0061] In a preferred embodiment, the interactive screen 32 is located on the side of the housing of the three-way air distribution seat 3 away from the air distribution wall 31, but this is not a limitation.

[0062] In a preferred embodiment, the air outlet 23 is connected to the main pipe of the three-way air distribution seat 3, and an air inlet mesh is provided at the bottom of the second end of the fan section 2. External air reaches the air inlet 22 of the fan section 2 through the air inlet mesh.

[0065] The housing of the second diffuser 5 is provided with a second slit nozzle 51. The extension direction of the second slit nozzle 51 is parallel to the second rotation axis, but not limited thereto.

[0066] In a preferred embodiment, a first heating element is provided on both sides of the first slit nozzle 41, and a second heating element is provided on both sides of the second slit nozzle 51, but this is not a limitation.

[0067] In a preferred embodiment, the fan unit 2 is rotatably connected to the upper end of the lifting rod 1, but this is not a limitation.

[0068] In a preferred embodiment, the first rotation axis is perpendicular to the second rotation axis, and the rotation axis of the fan 21 is perpendicular to the lifting rod 1, but this is not a limitation.

[0069] The specific embodiments of this utility model are as follows:

[0070] refer to Figures 1 to 7As shown, the lifting base of the fan with a rotating shaft of this utility model includes a base and a lifting rod 1. A fan unit 2 is connected to the upper end of the lifting rod 1. The fan unit 2 includes an air inlet 22, an air outlet 23, and a fan 21 that generates airflow. An air outlet shroud 24 is provided on the air outlet side of the fan 21. The side of the air outlet shroud 24 facing away from the air inlet 22 is connected to the first end of a hollow rotating shaft 25. An interactive screen 32 is connected to the second end of the rotating shaft 25. A data cable 26 connecting the fan 21 and the interactive screen 32 is provided inside the rotating shaft 25. The nozzle is rotatably fitted onto a rotating shaft 25 between the fan unit 2 and the interactive screen 32. The nozzle includes a three-way air distribution seat 3, a first diffuser 4, and a second diffuser 5, each with an air outlet. The three-way air distribution seat 3 has a through hole 33 coaxial with the main airflow receiving pipe. The second end of the rotating shaft 25 passes through the main pipe of the three-way air distribution seat 3 and the through hole 33 to connect to the interactive screen 32, allowing the nozzle to rotate based on the rotating shaft 25 (in this embodiment, the rotating shaft 25 is a horizontal axis and coaxial with the rotation axis of the motor). Furthermore, since the main pipe of the three-way air distribution seat 3 is coaxial with the through hole 33, the rotating shaft 25 will not be torn during the rotation of the three-way air distribution seat 3 based on the fan unit 2.

[0071] The main pipe of the three-way air distribution seat 3 is rotatably connected to the air outlet 23 of the fan section 2 along the first rotation axis. The first diffuser 4 and the second diffuser 5 are rotatably connected to the two branch pipes of the three-way air distribution seat 3 along the second rotation axis. An air distribution wall 31 is provided inside the three-way air distribution seat 3. The air distribution wall 31 has a through hole 33 coaxial with the first rotation axis in the center. The through hole 33 is rotatably sleeved on the rotating shaft 25. The first end of the rotating shaft 25 is integrally formed with the air outlet cover 24. The air distribution wall 31 includes an air distribution tip and guide slopes on both sides. Air flows through the guide slopes of the air distribution tip and is guided to the first diffuser 4 and the second diffuser 5 to be emitted outward. The interactive screen 32 is located on the side of the outer shell of the three-way air distribution seat 3 away from the air distribution wall 31. The air outlet 23 is connected to the main pipe of the three-way air distributor 3. An air inlet mesh is provided at the bottom of the second end of the fan unit 2. External air reaches the air inlet 22 of the fan unit 2 through the air inlet mesh. The three-way air distributor 3 is rotatably engaged with the air outlet 23 of the fan unit 2. In this invention, the main pipe of the three-way air distributor 3 is rotatably engaged with the annular groove on the outer periphery of the air outlet 23 of the fan unit 2 via a claw along the first rotation axis. Simultaneously, the three-way air distributor 3 is also limited by a hollow rotating shaft 25 integrally formed with the air outlet cover 24 of the fan 21. The simultaneous use of these two connection structures greatly strengthens the limiting strength between the three-way air distributor 3 and the fan unit 2, ensuring the coaxiality of the nozzle and the fan unit, and effectively reducing the wobbling of the nozzle.

[0072] In this embodiment, the first diffuser 4 and the second diffuser 5 are symmetrically positioned based on the three-way air distribution seat 3. The housing of the first diffuser 4 is provided with a first slit nozzle 41, the extension direction of which is parallel to the second rotation axis. The housing of the second diffuser 5 is provided with a second slit nozzle 51, the extension direction of which is parallel to the second rotation axis. First heating elements are provided on both sides of the first slit nozzle 41, and second heating elements are provided on both sides of the second slit nozzle 51. The fan unit 2 is horizontally rotatably connected to the upper end of the lifting rod 1. The first rotation axis is perpendicular to the second rotation axis, and the rotation axis of the fan 21 is perpendicular to the lifting rod 1. In this invention, the data cable 26 is shielded and protected by the rotating shaft 25 to prevent it from being directly blown by the high-speed airflow. The second end is electrically connected to the interactive screen 32, allowing the user to directly control the working status of the fan 21 by operating the interactive screen 32. This provides an interactive experience with the front interactive screen, significantly shortens the operating distance when using the fan, and is not affected by the rotation of the nozzle components, thereby improving the interaction efficiency and user experience between the user and the fan.

[0073] In summary, the purpose of this utility model is to provide a fan with a rotating shaft, which can place the fan control buttons at the front end of the fan, thereby shortening the operating distance for the user when using the fan and being unaffected by the rotation of the nozzle, thus improving interaction efficiency and user experience.

[0074] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
