Description

Technical Field

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

[0002] Currently, traditional desktop fans on the market output airflow through large fan blades connected to the motor output shaft, causing the coaxial guide grid to rotate and thus spread the airflow in different directions. However, this structure is usually large and occupies a lot of desktop space.

[0003] While bladeless fans effectively reduce size, their airflow direction is typically unidirectional. The only way to change the airflow direction is by rotating the base, resulting in limited impact on room airflow and hindering effective air circulation. Furthermore, the longer internal ductwork of bladeless fans, especially with bends or rotations, can compromise airtightness, leading to a decrease in overall airflow.

[0004] Therefore, this invention provides a fan with a rotating diffuser. Utility Model Content

[0119] This invention also provides a third type of fan with a rotating diffuser. Based on the second type of fan with a rotating diffuser, each of the branch pipes on both sides of the three-way air distribution seat 3 is provided with a second damping sealing rotating assembly (equivalent to the "second damping sealing assembly" in the first type of fan with a rotating diffuser). The first end of the diffuser is rotatably inserted into the second damping sealing rotating assembly along the second rotation axis. The second damping sealing rotating assembly provides rotational damping to the outer wall of the first end of the diffuser and forms an airtight seal. The second damping sealing rotating assembly includes at least a second sealing pipe with a second arc-shaped rack 381. The second arc-shaped rack 381 is driven by a second motor 63 to drive the diffuser to rotate independently based on the three-way air distribution seat 3. The second type of fan with a rotating diffuser of this invention can drive the nozzle part to rotate based on the fan part 2 through the cooperation of the first motor 61 and the first arc-shaped rack 381, and can also drive the diffuser to rotate based on the three-way air distribution seat 3 through the cooperation of the second motor 63 and the second arc-shaped rack 381, thereby achieving automatic rotation in all directions to meet different product requirements.

[0120] The specific embodiments of this utility model are as follows:

[0121] refer to Figures 1 to 8 As shown, this utility model discloses a fan with a rotating diffuser, comprising: a lifting base, a fan section 2, and a nozzle section. The lifting base includes a base and a lifting rod 1. The fan section 2 is connected to the upper end of the lifting rod 1 and includes a fan 21 that generates airflow, an air inlet 22 and an air outlet 23 located at opposite ends of the fan 21, and the air outlet 23 is provided with a first damping sealing kit. The nozzle section includes a three-way air distribution seat 3 and two diffusers. The main pipe of the three-way air distribution seat 3 is rotatably inserted into the first damping sealing kit along a first rotation axis. The first damping sealing kit provides rotational damping to the outer wall of the main pipe and forms an airtight seal. The branch pipes on both sides of the three-way air distribution seat 3 are each provided with a second damping sealing kit. The first end of the diffuser is rotatably inserted into the second damping sealing kit along a second rotation axis. The second damping sealing kit provides rotational damping to the outer wall of the first end of the diffuser and forms an airtight seal. The first diffuser 4 and the second diffuser 5 are symmetrically positioned based on the three-way air distribution seat 3. The three-way air distribution seat 3 has an air distribution wall 31 inside. The air distribution wall 31 includes an air distribution tip and guide slopes on both sides. The air flows through the guide slopes of the air distribution tip and is guided to the first diffuser 4 and the second diffuser 5 respectively.

[0122] The first damping sealing assembly includes a first fixing seat 32, a first sealing ring 33, a first bushing 35, and a first damper 34. The first fixing seat 32 is screwed to the inner wall of the air outlet 23. The first fixing seat 32 includes a first side and a second side formed sequentially along the airflow direction. The first sealing ring 33 is disposed on the first side of the first fixing seat 32, forming an airtight seal with the main pipe to ensure that no airflow leakage occurs during rotation. The first bushing 35 is disposed on the second side of the first fixing seat 32, and the circumference of the first bushing 35 is partially hollowed out to form several first free portions. The first damper 34 is disposed on the first fixing seat 32 and located on the outer periphery of the first bushing 35. The first damper 34 provides a biasing force to the first free portions of the first bushing 35 to form rotational damping of the main pipe of the nozzle section. This ensures that when the nozzle section (three-way air distribution seat 3) rotates relative to the fan section 2, the main pipe of the nozzle section is both circumferentially supported by the first bushing 35 and damped by the bias force provided by the first damper 34 in conjunction with the first free part of the first bushing 35, so that the nozzle section can be stabilized relative to the fan section 2 at any angle.

[0123] The second damping sealing assembly includes: a second fixed seat 36, a second sealing ring 39, a second bushing 38, and a second damper 37. The second fixed seat 36 is screwed to the inner wall of the branch pipe and includes a first side and a second side formed sequentially along the airflow direction. The second sealing ring 39 is disposed on the first side of the second fixed seat 36, forming an airtight seal with the first end of the diffuser to ensure no airflow leakage during rotation. The second bushing 38 is disposed on the second side of the second fixed seat 36, and its circumference is partially hollowed out to form several second free portions. The second damper 37 is disposed on the second fixed seat 36 and located on the outer periphery of the second bushing 38. The second damper 37 provides a biasing force to the second free portions of the second bushing 38 to form rotational damping on the first end of the diffuser. This ensures that when the first end of the diffuser rotates based on the three-way air distribution seat 3, the first end of the diffuser is both circumferentially supported by the second bushing 38 and damped by the bias force provided by the second damper 37 in conjunction with the first free part of the second bushing 38, so that the diffuser can remain stable relative to the three-way air distribution seat 3 at any angle.

[0124] Although the fan with a rotating diffuser in the first embodiment of this utility model allows users to manually rotate the air outlet (e.g., by holding the diffuser and rotating it), the relatively large number of rotating parts makes it prone to overall shaking during rotation, resulting in a poor appearance and affecting the user experience. Furthermore, (compared to traditional fans) it lacks the function of automatically rotating to adjust the airflow direction.

Figure 10This is a top cross-sectional view of a fan with a rotating diffuser, according to a second embodiment of the present invention. Figure 11 This is a perspective view of the fan with a rotating diffuser in the second embodiment of the present invention, with part of the three-way air distribution housing removed.

Figures 9 to 12 As shown, in the second embodiment of the fan with a rotating diffuser, based on the first embodiment of the fan with a rotating diffuser, rotating components are added to the three-way air distribution seat 3, the first diffuser 4, and the second diffuser 5 respectively. The specific structure is as follows: the first fixed seat 32 is provided with a first notch, and the outer periphery of the first bushing 35 is provided with a first arc-shaped rack 351, which protrudes from the first notch; the fan part 2 also includes a first motor 61, which is located on one side of the air outlet 23. The first gear 62 of the first motor 61 meshes with the first arc-shaped rack 351 and is driven by the first motor 61. The transmission nozzle part rotates based on the fan part 2. Furthermore, the second fixed base 36 is provided with a second notch, and the outer periphery of the second bushing 38 is provided with a second arc-shaped rack 381, which protrudes from the second notch; a second motor 63 is provided on each side of the three-way air distribution base 3, and the second gear 64 of the second motor 63 meshes with the second arc-shaped rack 381. With the transmission of the second motor 63, the diffuser rotates based on the three-way air distribution base 3. This allows the user to control the rotation of the three-way air distribution base 3 based on the fan unit 2 via remote control or buttons, driven by the first motor 61, or by the second motor 63, driven by the first diffuser 4 and the second diffuser 5 based on the three-way air distribution base 3. Since the first motor 61 and the second motor 63 are both stepper motors, they can rotate at a uniform low speed, ensuring that the whole machine does not shake during rotation, thereby improving the user experience. In addition, by combining these three rotating structures, the fan with a rotating diffuser in the second embodiment can achieve horizontal and vertical rotational airflow, and different airflow directions can be achieved by rotating the stroke, thus also having the function of automatically rotating and adjusting the airflow direction.

[0125] In summary, the purpose of this utility model is to provide a fan with a rotating diffuser, which can provide multiple damped and airtight rotating connections for the nozzle and fan parts, provide multiple air outlet angles for the fan, and ensure the overall airtightness of the air passage during the rotation of the nozzle part, thereby optimizing the user experience.

[0126] 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.
