Specifically, the springless duct motor includes a rotor assembly, a stator assembly, a duct, and an impeller. The stator assembly, duct, and impeller are all mounted on the rotor assembly. The rotor assembly includes a rotor shaft and bearings. The bearings are connected to the rotor shaft. The duct has bearing mounting holes, and the bearings are located inside the bearing mounting holes. No springs are installed inside the bearing mounting holes. The bearings are sleeved on the rotor shaft and bonded to the rotor shaft. The bearings are divided into a first bearing and a second bearing, which are respectively glued to both ends of the bearing mounting cavity.

[0003] It should be noted that the aforementioned springless fan motor still has the following drawbacks, specifically:

[0004] Defect 1: The air duct has a regular cylindrical structure, and the space on the side of the air duct near the impeller is small, which makes it impossible to deliver a large volume of air.

[0005] Defect 2: Reducing the overall weight by simply eliminating the spring structure does not result in a significant weight reduction effect. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of high-speed duct motor to address the shortcomings of existing technologies. This new high-speed duct motor has a novel structural design, significant lightweight effect, and can achieve large air volume delivery.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0008] A novel high-speed air duct motor includes a main air duct, a stator assembly, a rotor assembly, and an impeller. The main air duct includes an outer cylinder arranged coaxially and an inner cylinder located inside the outer cylinder. An air duct is formed between the outer cylinder and the inner cylinder. A guide plate located in the air duct connects the outer cylinder and the inner cylinder. The outer cylinder, the inner cylinder, and the guide plate are an integral structure.

[0009] The inner cylinder has a stator fastening cavity and a shaft hole located at the lower end of the stator fastening cavity. The stator assembly is fastened in the stator fastening cavity of the inner cylinder. The rotor assembly is provided with a rotating shaft that passes through the shaft hole of the inner cylinder downwards. The rotating shaft is rotatably installed in the shaft hole by two ball bearings arranged at intervals.

[0010] The impeller is fastened to the lower end of the shaft and is located at the lower end of the air duct;

[0011] The main air duct is made of rigid plastic, and the outer cylinder, inner cylinder, and air guide plate are injection molded into a single structure.

[0012] The lower end of the air duct is flared, and the radial width of the flared part at the lower end of the air duct gradually decreases from bottom to top.

[0013] The outer contour of the lower end of the inner cylinder is conical.

[0014] The outer contour shape of the lower end of the inner cylinder is irregular.

[0015] The two ball bearings are respectively riveted to the shaft hole, with one ball bearing riveted to the upper end of the shaft hole and the other ball bearing riveted to the lower end of the shaft hole.

[0016] The upper and lower ends of the shaft hole are respectively inlaid with copper sleeves, and each ball bearing is riveted to the inner side of the corresponding copper sleeve.

[0017] The outer ring of each ball bearing is injection molded into an integral structure with the inner cylinder.

[0018] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0019] 1. The main air duct 1 is integrally injection molded from engineering plastic. Compared with the traditional alloy material air duct, the main air duct of this rigid plastic structure has the advantage of being lightweight. Compared with the existing technology, the lightweight effect of the new high-speed air duct motor of this utility model is more obvious.

[0020] 2. The lower end of the air duct is flared, and the impeller is located in the flared part of the air duct. This structural design can achieve large air volume delivery.

[0021] 3. Therefore, the new high-speed air duct motor of this utility model has the advantages of novel structural design, significant lightweight effect and ability to deliver large air volume. Attached Figure Description

[0030] The present invention will now be described in conjunction with specific embodiments.

[0031] Example 1, as Figures 1 to 3 As shown, a novel high-speed air duct motor includes a main air duct 1, a stator assembly 2, a rotor assembly 3, and an impeller 4. The main air duct 1 includes an outer cylinder 11 arranged coaxially and an inner cylinder 12 located inside the outer cylinder 11. An air duct 13 is formed between the outer cylinder 11 and the inner cylinder 12. A guide plate 14 located inside the air duct 13 connects the outer cylinder 11 and the inner cylinder 12. The outer cylinder 11, the inner cylinder, and the guide plate 14 are an integral structure.

[0032] Among them, such as Figures 2 to 5 As shown, the inner cylinder 12 has a stator fastening cavity 121 and a shaft hole 122 located at the lower end of the stator fastening cavity 121. The stator assembly 2 is fastened in the stator fastening cavity 121 of the inner cylinder 12. The rotor assembly 3 is provided with a rotating shaft 31 that passes downward through the shaft hole 122 of the inner cylinder 12. The rotating shaft 31 is rotatably installed in the shaft hole 122 by two ball bearings 5 ​​arranged at intervals.

[0033] Furthermore, such as Figures 2 to 5 As shown, the impeller 4 is fastened to the lower end of the rotating shaft 31 and the impeller 4 is located at the lower end of the air duct 13.

[0034] Furthermore, the main air duct 1 is made of rigid plastic, and the outer cylinder 11, inner cylinder 12, and air guide plate 14 are injection molded into an integral structure; it should be explained that the main air duct 1 of this embodiment can be injection molded from high-performance engineering plastics such as PEEK or PPS.

[0035] In addition, such as Figure 2 and Figure 3As shown, the lower end of the air duct 13 is flared, and the radial width of the flared portion 131 at the lower end of the air duct 13 gradually decreases from bottom to top; as Figure 2 and Figure 3 As shown, the upper end of the air duct 13 is a regular cylinder. It should be explained that the flared part 131 of the air duct 13 can be determined by the shape of the lower end of the inner cylinder 12. Specifically, the outer contour shape of the lower end of the inner cylinder 12 is conical, or the outer contour shape of the lower end of the inner cylinder 12 is irregular.

[0036] It should be emphasized that the main air duct 1 of this embodiment can be integrally injection molded from engineering plastic. Compared with traditional alloy material air ducts, the main air duct 1 of this rigid plastic structure has the advantage of being lightweight. Compared with the prior art, the lightweight effect of the new high-speed air duct motor of this embodiment is more obvious.

[0037] It should be further emphasized that, for the new high-speed air duct motor of this embodiment, the lower end of its air duct 13 is flared, and the impeller 4 is located at the flared part 131 of the air duct 13. This structural design can achieve large air volume delivery.

[0038] In summary, the novel high-speed air duct motor of this embodiment has the advantages of novel structural design, significant lightweight effect, and ability to deliver large air volume through the above structural design.

[0039] Example 2, as Figures 2 to 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the two ball bearings 5 ​​are respectively riveted in the shaft hole 122, one ball bearing 5 is riveted to the upper end of the shaft hole 122, and the other ball bearing 5 is riveted to the lower end of the shaft hole 122.

[0040] Compared to the existing bearing adhesive fixing method, the ball bearing 5 installation method in this embodiment 2 has the advantages of better assembly method and stability and reliability.

[0041] Example 3, as Figure 4 As shown, the difference between this embodiment three and embodiment two is that: the upper end and lower end of the shaft hole 122 are respectively inlaid with copper sleeves 6, and each ball bearing 5 is respectively riveted to the inner side of the corresponding copper sleeve 6.

[0042] Example 4, as Figure 5 As shown, the difference between this embodiment four and embodiment one is that the outer ring of each ball bearing 5 and the inner cylinder 12 are injection molded into an integral structure.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
