DETAILED DESCRIPTION

[0034] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The existing fan has two impellers, and when the two air ducts are close to each other, the problem of fluid interference often occurs. In the utility model, at least two impeller assemblies are arranged parallel and spaced in the axial direction and installed on the bracket; the air duct assembly is installed on the bracket to form two isolated air ducts at the two impeller assemblies. Through the air duct assembly, the two air ducts formed by the two impeller assemblies are effectively isolated, which helps to reduce the mutual interference between the air flows.

[0036] Please refer to Figure 1 and Figure 2In one embodiment, a fan module is provided for a bladeless fan lamp. The fan module includes at least two impeller assemblies 100, an air duct assembly 200, a panel 300 and a bracket 400. At least two impeller assemblies 100 are arranged in parallel and spaced apart in the axial direction and are installed on the bracket 400. The air duct assembly 200 is installed on the bracket 400 to form two isolated air ducts at the two impeller assemblies 100, so that the wind flows generated by the two impeller assemblies 100 do not interfere with each other. The panel 300 is installed on the bracket 400, and the panel 300 is provided with an air outlet 310 that matches the air outlet direction of the air duct. The wind flows out through the air outlet 310 on the panel 300 and diffuses to the surroundings.

[0037] In one embodiment, the air duct assembly 200 includes a partition 210 disposed between two impeller assemblies 100, and a top plate 220 connected to the partition 210 and disposed on both sides thereof. Such a design forms a complete air duct structure. The air inlet is disposed between the top plate 220 and the panel 300 as a channel for the airflow to enter. Under the guidance of the top plate 220, the airflow flows along a predetermined path. Two isolated air ducts are formed at the two impeller assemblies 100, and the existence of the partition 210 separates the airflow of the two air ducts to avoid mutual interference. Finally, the airflow diffuses to the surroundings through the air outlet 310, and the partition 210 also has the function of optimizing wind noise and air volume.

[0038] See also Figure 2 In one embodiment, the connecting section of the partition 210 and the top plate 220 is an arc section that matches the outer contour of the impeller assembly 100. This arc-shaped design not only achieves the separation of the air duct and the stability of the structure, but also guides the wind flow downward. Each impeller assembly can work independently in its corresponding air duct, and the isolated air duct design effectively avoids mutual interference of airflows between different impeller assemblies. A fixing hole 221 is provided on the top plate 220, and the fixing hole 221 cooperates with the fixing structure so that the fan module can be fixed on the ceiling.

[0039] In one embodiment, the air duct assembly 200 is formed by splicing a first volute member 230 and a second volute member 240, presenting a unique "V"-shaped structure. The wind flow is effectively guided to a predetermined direction to ensure a stable and smooth flow state in the air duct. The two impeller assemblies 100 are respectively installed inside the first volute member 230 and the second volute member 240. The spliced ​​volute members form a partition 210 and separate two independent air ducts to ensure that the wind flow flows in their respective channels in an orderly manner, thereby avoiding the mutual interference of airflows that may be generated between different air ducts. The unspliced ​​parts naturally extend to both sides to form a top plate 220, which has a sealing effect to prevent external factors from affecting the wind flow in the air duct.

[0040] See also Figure 3 , Figure 4 and Figure 5 In one embodiment, the bracket 400 includes a first fixing plate 410 and a second fixing plate 420 separately arranged at both ends of the impeller assembly 100. Each impeller assembly 100 includes an impeller motor 110 fixedly mounted on the first fixing plate 410, and an impeller 111 rotatably mounted between the first fixing plate 410 and the second fixing plate 420 and driven to rotate by the impeller motor 110. When the impeller motor 110 receives a start signal, it starts to operate. The rotational force of the motor is transmitted to the impeller 111 through the transmission mechanism, driving it to start rotating. The bracket 400 provides a stable support so that the impeller 111 can maintain a stable working state during the rotation process. As the impeller 111 rotates, air is sucked in and pushed by the rotation of the impeller, thereby generating airflow. These airflows pass through the air duct assembly and the air outlet, and the airflow is diffused to the surroundings through the air outlet 310. The stable support of the bracket 400 combined with the operation of the impeller assembly 100 ensures that the fan module can output airflow stably and efficiently to meet the user's use needs.

[0041] In one embodiment, the fan module further includes a flap assembly 500 disposed at the air outlet 310 for adjusting the air outlet direction.

[0042] See also Figure 6 In one embodiment, the swing leaf assembly 500 includes at least one air guide 510 disposed at the air outlet 310, and a swing leaf drive motor 530 installed on the bracket 400 to drive the air guide 510 to rotate. Driven by the swing leaf drive motor 530, the air guide 510 can rotate, thereby changing the opening and closing direction and angle of the air outlet 310.

[0043] Specifically, the air guide member can be made of aluminum profiles, and the shape can be blade-shaped, plate-shaped or other shapes that can effectively guide airflow. Each air guide member 510 is connected to the swing leaf drive motor 530 through a connector. The air guide member 510 can also be equipped with a damping mechanism to ensure a stable damping effect during the rotation process to avoid rotating too fast or too slow.

[0044] Furthermore, the specific implementation process may be: the user sends instructions to the fan module through a remote control, a smart device or a control panel to adjust the working state of the swing leaf assembly 500. The control system receives and interprets these instructions, and then sends corresponding rotation angle and speed instructions to the swing leaf drive motor 530. After receiving the instructions, the motor starts to operate as required, and transmits the rotation torque to the air guide 510 through the transmission mechanism.

[0045] Driven by the motor, the air guide 510 starts to rotate, changing the opening and closing degree and wind direction of the air outlet 310 according to the command requirements. During the rotation process, the position sensor monitors the rotation position and speed of the air guide in real time to ensure precise control. As the air guide rotates, the wind direction and wind flow distribution of the air outlet change, meeting the different wind direction and wind speed adjustment requirements of users.

[0046] In one embodiment, there are multiple air guides 510; the swing leaf assembly 500 also includes a connecting rod 520 connecting the multiple air guides 510; the swing leaf drive motor 530 drives the connecting rod 520 to drive the multiple air guides 510 to rotate synchronously.

[0047] See also Figure 7 The utility model also provides a bladeless fan lamp, including the above-mentioned fan module, and a lamp group 700 installed at the lower side of the fan module, and the lamp group 700 is provided with a lamp group air outlet 710 corresponding to the air outlet 310 of the fan module.

[0048] In one embodiment, a shock-absorbing and buffering component 600 is provided between the lamp assembly 700 and the panel 300 of the fan module. The shock-absorbing and buffering component 600 may be a mute cotton, which is used to buffer the contact between the fan assembly and the lamp assembly 700 and remove abnormal noise.

[0049] Through the design of a fan module and a bladeless fan lamp of the utility model, the utility model sets an air duct assembly and installs the air duct assembly on a bracket to form two isolated air ducts at the two impeller assemblies. Each impeller assembly can work independently in its corresponding air duct. The isolated air duct design effectively avoids mutual interference of airflows between different impeller assemblies.

A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
