Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and more particularly to a fan dust cover structure and electronic device. Background Technology

[0002] Electronic devices generate significant heat during computation and processing. Overheating of internal components not only affects the operational efficiency of these devices but can also lead to damage. Therefore, it is necessary to incorporate air inlets into electronic devices, using fans to draw in cool air to cool the internal components.

[0003] In existing technologies, the "dust trapping" structure of the fan flow channel and fan blades, the arc design of the fan blades, and the gaps between the blades cause particles to accumulate due to "electrostatic adsorption," resulting in the long-term accumulation of flocculent / blocky dust. This leads to the fan blades becoming stuck and the airflow being significantly reduced.

[0004] Its drawback is that the electrostatic adsorption of particles on the fan blades forms flocculent / clump-like dust, which affects the fan's cooling effect.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this application is to provide a fan dust cover structure and electronic device to solve the problem that existing fan blades are affected by the formation of flocculent / blocky dust due to electrostatic adsorption of particles, which affects the cooling effect of the fan.

[0007] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution: On one hand, this application provides a fan dust cover structure, including: Shell section; Rotatably connected to the connecting shaft on the housing portion; A fan blade portion sleeved on the connecting shaft, the fan blade portion being in communication with the connecting shaft; The connecting shaft has a friction plate at one end facing the housing portion, and the friction plate is in communication with the housing portion.

[0008] In some embodiments, a drive portion is sleeved on the outer wall of the connecting shaft, and the fan blade portion is sleeved on the outer wall of the drive portion.

[0009] In some embodiments, the drive unit is a motor, and the fan blades are sleeved on the rotor of the motor.

[0010] In some embodiments, the housing portion includes an outer shell and a copper tube, the copper tube being sleeved on the connecting shaft and the connecting shaft being rotatable relative to the copper tube; the copper tube passes through the stator of the motor, and the outer shell is sleeved on the outer wall of the copper tube.

[0011] In some embodiments, the copper tube is axially bent along one end of the connecting shaft and extends circumferentially to form a concave structure, and the friction pad is mounted on the inner bottom wall of the copper tube.

[0012] In some embodiments, a bearing is fitted on the outer wall of the connecting shaft, and the outer wall of the bearing abuts against the inner wall of the copper tube.

[0013] In some embodiments, a positioning ring is fitted onto the outer end of the bearing, and the positioning ring abuts against the inner wall of the copper tube.

[0014] In another aspect, this application provides an electronic device including the aforementioned fan dust cover structure.

[0015] Compared with the prior art, the beneficial effects achieved by this application are as follows: This invention connects the fan blade to the connecting shaft, with the connecting shaft contacting the friction plate and the friction plate communicating with the housing. This allows the charge on the fan blade to be transmitted along the direction from the connecting shaft and friction plate to the housing, thus preventing the accumulation of particles on the fan blade due to electrostatic adsorption, which would lead to the formation of flocculent / lumpy dust over time. This, in turn, improves the stability of the equipment during use and extends its service life. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1:

[0020] This embodiment describes a fan dust cover structure, including: Casing part 1; Rotate the connecting shaft 2 connected to the housing part 1; The fan blade 3 is sleeved on the connecting shaft 2, and the fan blade 3 is in communication with the connecting shaft 2; Among them, the end of the connecting shaft 2 facing the housing part 1 is in contact with the friction plate 4, and the friction plate 4 is in communication with the housing part 1.

[0021] according to Figure 1 Those skilled in the art can configure the housing portion 1 and the connecting shaft 2 to be interconnected, and the connecting shaft 2 can rotate relative to the housing portion 1. In one embodiment, the connecting shaft 2 can be configured to be connected at the middle position of the housing portion 1.

[0022] A fan blade portion 3 is fitted onto the connecting shaft 2, so that the fan blade portion 3 can rotate during the rotation of the connecting shaft 2. Furthermore, a friction plate is in contact with the end of the connecting shaft 2 facing the housing portion 1.

[0023] In the above structure, the fan blade 3 can be connected to the connecting shaft 2 at the same time, and the connecting shaft 2 can also be connected when it contacts the friction plate 4. The friction plate 4 is connected to the housing 1, so that the charge on the fan blade 3 can be transferred to the housing 1.

[0024] Through the aforementioned conductive structure, static electricity on the fan blade 3 can be removed, thereby effectively preventing particles from accumulating and forming flocculent / lumpy dust due to "static adsorption," which in turn improves the stability of the equipment during use and extends its service life.

[0025] In some embodiments, the outer wall of the connecting shaft 2 is fitted with a driving part 5, and the fan blade part 3 is fitted on the outer wall of the driving part 5.

[0026] In this embodiment, the drive unit 5 can drive the connecting shaft 2 and the fan blade 3 to rotate. Specifically, as not shown in the figure, the connecting shaft 2 can be installed through the drive unit 5, and the drive unit 5 drives the connecting shaft 2 to rotate, which in turn causes the fan blade 3 to rotate.

[0027] In the above structure, the charge on the fan blade 3 can be transferred to the outer wall of the drive unit 5, and then transferred from the drive unit 5 along the direction of the connecting shaft 2, the friction plate 4 and the housing 1, so that the fan blade 3 will not generate flocculent / lumpy dust due to static electricity.

[0028] Preferably, the drive unit 5 is a motor, and the fan blade 3 is sleeved on the rotor 51 of the motor. That is, in the structure driven by a motor, the fan blade 3 is fixedly sleeved on the rotor 51. The motor rotor 51 is sleeved on the connecting shaft 2, so that the charge on the fan blade 3 can be transferred to the connecting shaft 2 through the rotor 51.

[0029] With the above settings, the process of transferring charge on the fan blade 3 can be realized in the motor-driven structure, thereby avoiding the generation of flocculent / clump-like dust on the fan blade 3 due to static electricity.

[0030] In some embodiments, the housing portion 1 includes an outer shell 11 and a copper tube 12, the copper tube 12 being sleeved on the connecting shaft 2 and the connecting shaft 2 being rotatable relative to the copper tube 12; the copper tube 12 is inserted into the stator 52 of the motor, and the outer shell 11 is sleeved on the outer wall of the copper tube 12.

[0031] The copper tube 12 is rotatably connected to one end of the connecting shaft 2, and the outer shell 11 is fitted on the outer wall of the copper tube 12. The friction plate 4 is in communication with the outer shell 11.

[0032] The above structure makes the structure between the fan blade 3 and the connecting shaft 2 more stable, so that the charge on the fan blade 3 can be stably discharged during the rotation of the fan blade 3.

[0033] With the above structure, the generation of flocculent / clump-like dust due to static electricity during the rotation of the fan blades 3 can be avoided.

[0034] Preferably, the copper tube 12 is axially bent along one end of the connecting shaft 2 and extends circumferentially to form a concave structure, and the friction plate 4 is installed on the inner bottom wall of the copper tube 12.

[0035] The connecting shaft 2 is inserted into the concave copper tube 12, the friction plate 4 is installed on the inner bottom wall of the copper tube 12, the connecting shaft 2 contacts and conducts with the friction plate 4, the friction plate contacts and conducts with the copper tube 12, and the copper tube 12 contacts and conducts with the outer shell.

[0036] The above structure not only makes the connection structure of the connecting shaft 2 more stable, but also significantly improves the stability of the relative position of the friction plate 4, making the charge transfer process more stable.

[0037] More preferably, a bearing 6 is fitted onto the outer wall of the connecting shaft 2, and the outer wall of the bearing 6 abuts against the inner wall of the copper tube 12. By installing the bearing 6 between the connecting shaft 2 and the copper tube 12, the copper tube 12 can remain stationary, while the connecting shaft 6 rotates stably under the action of the motor.

[0038] It is understandable that the stable rotation of the connecting shaft 6 allows the friction plate 4 to maintain stable contact with the connecting shaft 6, thereby making the charge conduction process more stable.

[0039] Those skilled in the art can fit a positioning ring 7 on the outer end of the bearing 6, with the positioning ring 7 abutting against the inner wall of the copper tube 12. The positioning ring 7 can fix the relative position of the bearing 6, thereby preventing the bearing 6 from loosening during rotation, which in turn improves the stability of the connection between the friction plate 4 and the connecting shaft 2, prevents the fan blade 3 from generating flocculent / lumpy dust due to static electricity, and significantly improves the service life of the fan blade 3. Example 2:

[0040] This embodiment provides an electronic device including the aforementioned fan dust cover structure, which can effectively prevent the fan blades of the cooling fan in the electronic device from generating flocculent / lumpy dust due to static electricity, and significantly improve the service life of the electronic device.
