Abstract
Description
Technical Field
[0001] The present application relates to a fan, and in particular to an antistatic fan wheel and a fan having the fan wheel. Background Art
[0002] As modern electronic devices develop towards high performance and high speed, the heat energy generated by each electronic device during operation also increases accordingly, which reduces the reliability of electronic components or shortens their service life. Therefore, many electronic devices are equipped with fans to cool down and dissipate heat from electronic components.
[0003] However, the above-mentioned fans are mostly made of plastic materials, which are easy to generate or even accumulate static electricity due to frictional contact. Once the fan accumulates a large amount of static electricity during processing and use, the construction workers or terminal users are prone to static electricity pain when touching the fan, and the fan may absorb hair or dust, etc., which has long been criticized.
[0004] Therefore, how to overcome the above-mentioned deficiencies of the prior art is a major issue that the inventors of this application are eager to solve. Utility Model Content
[0005] The purpose of the present application is to provide an antistatic impeller and a fan having the impeller, wherein the impeller is molded by mixing plastic material and antistatic material into a plastic antistatic composite material to have an antistatic effect.
[0006] In order to achieve the above-mentioned objectives, the present application provides an antistatic impeller, comprising: a hub having a circumferential surface; and a plurality of blades, all connected to the circumferential surface, and the hub and the plurality of blades are injection molded with a plastic antistatic composite material, the plastic antistatic composite material containing 70 to 90wt% of a plastic material and 10 to 30wt% of an antistatic material mixed with each other.
[0007] The present application further provides a fan with an antistatic fan wheel, comprising: a fan frame having an inner space; and an antistatic fan wheel as described above, the antistatic fan wheel being rotatably disposed on the fan frame corresponding to the inner space.
[0008] Compared with the prior art, the present application has the following effects: since the fan wheel is injection molded by mixing 70 to 90wt% of plastic material and 10 to 30wt% of antistatic material into a plastic antistatic composite material, the fan wheel has an antistatic effect, so that the manufacturer or the terminal user will not have the problem of static electricity pain when touching the fan wheel, and the fan wheel is not easy to absorb dirt such as hair or dust.

[0019] The detailed description and technical contents of the present application are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and explanation and are not intended to limit the present application.
[0020] like Figures 1 to 4 As shown, the present application provides an antistatic impeller and a fan having the impeller. The fan having the antistatic impeller (hereinafter referred to as the fan) comprises a fan frame 1 and an antistatic impeller 2. The fan frame 1 has an inner frame space 11. The antistatic impeller 2 is rotatably disposed in the fan frame 1 corresponding to the inner frame space 11.
[0021] like Figures 1 to 3 As shown, the antistatic impeller 2 of the present application comprises a hub 21 and a plurality of blades 22. The hub 21 has a circumferential surface 2111, one end of each blade 22 is connected to the circumferential surface 2111, and the hub 21 and all the blades 22 are injection molded with a plastic antistatic composite material A. The plastic antistatic composite material A comprises 70 to 90 wt% of a plastic material and 10 to 30 wt% of an antistatic material mixed with each other.
[0022] Thereby, the antistatic fan wheel 2 of the present application has a special antistatic effect, so that the manufacturer or the terminal user will not have the problem of static electricity pain when touching the antistatic fan wheel 2, and the antistatic fan wheel 2 itself is not easy to absorb dirt such as hair and dust.
[0023] It should be noted that the above-mentioned plastic material includes at least one of nylon, ABS resin and PBT resin; the above-mentioned antistatic material includes at least one of nano polymer antistatic agent, glass fiber, long carbon fiber, short carbon fiber and carbon nanotube.
[0024] Furthermore, the antistatic material mentioned above can be GYC-AT-50 sold on the market. GYC-AT-50 is a nano-polymer antistatic agent, which is mainly used in engineering plastics such as nylon, ABS resin, PBT resin and other alloy materials. GYC-AT-50 has excellent antistatic effect and is not affected by ambient temperature and humidity. It still maintains the antistatic effect after washing with water or wiping with a wet cloth. As a water-resistant and long-lasting antistatic agent, GYC-AT-50 can be made into antistatic masterbatch and applied to various blow molding, extrusion, and extrusion products, with a wide range of applications.
[0025] In addition, the plastic antistatic composite material A can also be PBT polymer long-term antistatic material, PBT plus glass fiber long-term antistatic material, PBT fireproof long-term antistatic material, PBT carbon black antistatic material, PBT carbon nanotube antistatic material or PBT carbon fiber antistatic material sold in the market. The above-mentioned PBT resin is used as the base material, and antistatic materials such as long carbon fiber or short carbon fiber are added, thereby having the advantages of antistatic, high strength, good mechanical durability, good heat resistance, good weather resistance, good dimensional stability, good processability, and black and bright surface.
[0026] Furthermore, when the weight proportion of the plastic material is greater than 90%, the weight proportion of the plastic antistatic composite material A will be less than 10%, and the antistatic effect will be weakened at this time; and when the weight proportion of the plastic material is less than 70%, the weight proportion of the plastic antistatic composite material A will increase to 30%, which will cause the manufacturing cost of the antistatic impeller 2 to be too high, so using 70-90wt% of plastic mixed with 10-30wt% of plastic antistatic composite material A is more in line with the manufacturing cost and antistatic effect of the antistatic impeller 2.
[0027] It should be noted that the antistatic impeller 2 further includes a spindle 23, one end of which is connected to the hub 21. The hub 21 has a circumference 211 and a cover plate 212, the circumference 211 surrounds and is connected to the periphery of the cover plate 212, and the circumference 211 has the aforementioned circumferential surface 2111, and the cover plate 212 has an inner end surface 2121, and one end of the spindle 23 is uprightly connected to the inner end surface 2121.
[0028] In addition, a rotor 4 is disposed in the hub 21 of the antistatic impeller 2 . The rotor 4 surrounds the aforementioned spindle 23 , and the rotor 4 can rotate along with the hub 21 .
[0029] like Figure 3 and Figure 4As shown, the fan of the present application has an antistatic fan wheel, that is, it is equipped with such an antistatic fan wheel 2 with antistatic effect. Therefore, the fan of the present application can also have an antistatic effect because of the antistatic fan wheel 2, and further, the manufacturer or the terminal user will not have the problem of static electricity pain when touching the antistatic fan wheel 2, and the antistatic fan wheel 2 itself is not easy to absorb dirt such as hair and dust.
[0030] It should be noted that the fan frame 1 has an upright bearing seat 12 in the aforementioned frame space 11, and a stator 3 is arranged around the outer periphery of the bearing seat 12. The anti-static fan wheel 2 is rotatably connected to the bearing seat 12 by the other end of its axis 23, so that the rotor 4 surrounds the stator 3, and the anti-static fan wheel 2 rotates relative to the fan frame 1 accordingly.
[0031] In summary, the antistatic impeller of the present application and the fan having the impeller can achieve the expected purpose and effect and solve the deficiencies of the prior art.
[0032] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
